Cellular System Components

Introduction to GSM Networks Figure 1. 1 is a schematic overview of the main components in a GSM network. The various interface labels are the formal names given to these interfaces. More details about these interfaces are found in GSM TS 03. 02 [26]. The GSM network consists mainly of the following functional parts: †¢ MSC – the mobile service switching centre (MSC) is the core switching entity in the network. The MSC is connected to the radio access network (RAN); the RAN is formed by the BSCs and BTSs within the Public Land Mobile Network (PLMN).Users of the GSM network are registered with an MSC; all calls to and from the user are controlled by the MSC. A GSM network has one or more MSCs, geographically distributed. †¢ VLR – the visitor location register (VLR) contains subscriber data for subscribers registered in an MSC. Every MSC contains a VLR. Although MSC and VLR are individually addressable, they are always contained in one integrated node. †¢ G MSC – the gateway MSC (GMSC) is the switching entity that controls mobile terminating calls.When a call is established towards a GSM subscriber, a GMSC contacts the HLR of that subscriber, to obtain the address of the MSC where that subscriber is currently registered. That MSC address is used to route the call to that subscriber. †¢ HLR – the home location register (HLR) is the database that contains a subscription record for each subscriber of the network. A GSM subscriber is normally associated with one particular HLR. The HLR is responsible for the sending of subscription data to the VLR (during registration) or GMSC (during mobile terminating call handling). CN – the core network (CN) consists of, amongst other things, MSC(s), GMSC(s) and HLR(s). These entities are the main components for call handling and subscriber management. Other main entities in the CN are the equipment identi? cation register (EIR) and authentication centre (AUC). CAMEL has no in teraction with the EIR and AUC; hence EIR and AUC are not further discussed. †¢ BSS – the base station system (BSS) is composed of one or more base station controllers (BSC) and one or more base transceiver stations (BTS). The BTS contains one or more transceivers (TRX).The TRX is responsible for radio signal transmission and reception. BTS and BSC are connected through the Abis interface. The BSS is connected to the MSC through the A interface. †¢ MS – the mobile station (MS) is the GSM handset. The structure of the MS will be described in more detail in a next section. A GSM network is a public land mobile network (PLMN). Other types of PLMN are the time division multiple access (TDMA) network or code division multiple access (CDMA) network. GSM uses the following sub-division of the PLMN: CAMEL: Intelligent Networks for the GSM, GPRS and UMTS Network ? 006 John Wiley & Sons, Ltd Rogier Noldus 2 CAMEL: Intelligent Networks for the GSM, GPRS and UMTS Network To HLR from other PLMN D HLR D C Core network To/from other network MSC ISUP E MSC A BSC Abis BTS Um Um A ISUP GMSC ISUP BSC Abis BTS Um Um Base station system Air interface MS MS MS MS Figure 1. 1 GSM network architecture †¢ Home PLMN (HPLMN) – the HPLMN is the GSM network that a GSM user is a subscriber of. That implies that GSM user’s subscription data resides in the HLR in that PLMN. The HLR may transfer the subscription data to a VLR (during registration in a PLMN) or a GMSC (during mobile terminating call handling).The HPLMN may also contain various service nodes, such as a short message service centre (SMSC), service control point (SCP), etc. †¢ Visited PLMN (VPLMN) – the VPLMN is the GSM network where a subscriber is currently registered. The subscriber may be registered in her HPLMN or in another PLMN. In the latter case, the subscriber is outbound roaming (from HPLMN’s perspective) and inbound roaming (from VPLMN’s perspective) . When the subscriber is currently registered in her HPLMN, then the HPLMN is at the same time VPLMN. 1 †¢ Interrogating PLMN (IPLMN) – the IPLMN is the PLMN containing the GMSC that handles mobile terminating (MT) calls.MT calls are always handled by a GMSC in the PLMN, regardless of the origin of the call. For most operators, MT call handling is done by a GMSC in the HPLMN; in that case, the HPLMN is at the same time IPLMN. This implies that calls destined for a GSM subscriber are always routed to the HPLMN of that GSM subscriber. Once the call has arrived in the HPLMN, the HPLMN acts as IPLMN. MT call handling will be described in more detail in subsequent sections. When basic optimal routing (BOR) is applied, the IPLMN is not the same PLMN as the HPLMN.The user of a GSM network is referred to as the served subscriber ; the MSC that is serving that subscriber is known as the serving MSC. Examples are: †¢ mobile originated call – the MSC that is handling th e call is the serving MSC for this call; the calling subscriber is the served subscriber; †¢ mobile terminated call – the GMSC that is handling the call is the serving GMSC for this call; the called subscriber is the served subscriber. 1 The CAMEL service requirement, GSM TS 02. 78 [12] uses this strict de? nition. The term VPLMN is, however, commonly used to denote any network other than the HPLMN.Introduction to GSM Networks 3 1. 1 Signalling in GSM The various entities in the GSM network are connected to one another through signalling networks. Signalling is used for example, for subscriber mobility, subscriber registration, call establishment, etc. The connections to the various entities are known as ‘reference points’. Examples include: †¢ †¢ †¢ †¢ A interface – the connection between MSC and BSC; Abis interface – the connection between BSC and BTS; D interface – the connection between MSC and HLR; Um interface à ¢â‚¬â€œ the radio connection between MS and BTS. Various signalling protocols are used over the reference points.Some of these protocols for GSM are the following: †¢ mobile application part (MAP) – MAP is used for call control, subscriber registration, short message service, etc. ; MAP is used over many of the GSM network interfaces; †¢ base station system application part (BSSAP) – BSSAP is used over the A interface; †¢ direct transfer application part (DTAP) – DTAP is used between MS and MSC; DTAP is carried over the Abis and the A interface. DTAP is speci? ed in GSM TS 04. 08 [49]; †¢ ISDN user part (ISUP) – ISUP is the protocol for establishing and releasing circuit switched calls.ISUP is also used in landline Integrated Services Digital Network (ISDN). A circuit is the data channel that is established between two users in the network. Within ISDN, the data channel is generally a 64 kbit/s channel. The circuit is used for the tran sfer of the encoded speech or other data. ISUP is speci? ed in ITU-T Q. 763 [137]. When it comes to call establishment, GSM makes a distinction between signalling and payload. Signalling refers to the exchange of information for call set up; payload refers to the data that is transferred within a call, i. e. voice, video, fax etc.For a mobile terminated GSM call, the signalling consists of exchange of MAP messages between GMSC, HLR and visited MSC (VMSC). The payload is transferred by the ISUP connection between GMSC and VMSC. It is a continual aim to optimize the payload transfer through the network, as payload transfer has a direct cost aspect associated with it. Some network services are designed to optimize the payload transfer. One example is optimal routing. 1. 2 GSM Mobility Roaming with GSM is made possible through the separation of switching capability and subscription data.A GSM subscriber has her subscription data, including CAMEL data, permanently registered in the HLR i n her HPLMN. The GSM operator is responsible for provisioning this data in the HLR. The MSC and GMSC in a PLMN, on the other hand, are not speci? c for one subscriber group. The switching capability of the MSC in a PLMN may be used by that PLMN’s own subscribers, but also by inbound roaming subscribers; see Figure 1. 2. In Figure 1. 2, the GSM user who is a subscriber of PLMN-A roams to PLMN-B. The HLR in PLMN-A transfers the user’s subscription data to the MSC in PLMN-B.The subscriber’s subscription data remains in the MSC/VLR as long as she is served by a BSS that is connected to that MSC. Even when the user switches her MS off and then on again, the subscription data remains in the MSC. After an extended period of the MS being switched off, the subscription data will be purged from the MSC. When the subscriber switches her MS on again, the subscriber has to re-register with the MSC, which entails the MSC asking the HLR in the HPLMN to re-send the subscription data for that subscriber. 4 CAMEL: Intelligent Networks for the GSM, GPRS and UMTS NetworkTransfer of subscription data to MSC/VLR HLR PLMN-A MSC MS Subscriber roams to other PLMN PLMN-B MSC Figure 1. 2 Transfer of GSM subscription data for a roaming subscriber When the subscriber moves from one MSC service area (MSC-1) to another MSC service area (MSC-2), the HLR will instruct MSC-1 to purge the subscription data of this subscriber and will send the subscription data to MSC-2. 1. 3 Mobile Station The MS, i. e. the GSM handset, is logically built up from the following components: †¢ mobile equipment (ME) – this is the GSM terminal, excluding the SIM card; †¢ subscriber identi? ation module (SIM) – this is the chip embedded in the SIM card that identi? es a subscriber of a GSM network; the SIM is embedded in the SIM card. When the SIM card is inserted in the ME, the subscriber may register with a GSM network. The ME is now effectively personalized for this GS M subscriber; see Figure 1. 3. The characteristics of the SIM are speci? ed in GSM TS 11. 11. The SIM card contains information such as IMSI, advice of charge parameters, operator-speci? c emergency number, etc. For the UMTS network an enhanced SIM is speci? ed, the universal subscriber identity module (USIM); refer 3GPP TS 31. 02. 1. 4 Identi? ers in the GSM Network GSM uses several identi? ers for the routing of calls, identifying subscribers (e. g. for charging), locating the HLR, identifying equipment, etc. Some of these identi? ers play an important role for CAMEL. 1. 4. 1 International Mobile Subscriber Identity The international mobile subscriber identity (IMSI) is embedded on the SIM card and is used to identify a subscriber. The IMSI is also contained in the subscription data in the HLR. The IMSI is used for identifying a subscriber for various processes in the GSM network. Some of these are: KPN SIM + ME = MSFigure 1. 3 Components of the mobile station Introduction to GSM Networks 5 3 digits MCC Maximum 15 digits 2 or 3 digits MNC MSIN Figure 1. 4 Structure of the IMSI †¢ location update – when attaching to a network, the MS reports the IMSI to the MSC, which uses the IMSI to derive the global title (GT) of the HLR associated with the subscriber; †¢ terminating call – when the GSM network handles a call to a GSM subscriber, the HLR uses the IMSI to identify the subscriber in the MSC/VLR, to start a process for delivering the call to that subscriber in that MSC/VLR. †¢ roaming charging – a VPLMN uses the IMSI o send billing records to the HPLMN of a subscriber. Figure 1. 4 shows the format of the IMSI. †¢ mobile country code (MCC) – the MCC identi? es the country for mobile networks. The MCC is not used for call establishment. The usage of MCC is de? ned in ITU-T E. 212 [129]. The MCC values are allocated and published by the ITU-T. †¢ mobile network code (MNC) – the MNC identi? es the mobile network within a mobile country (as identi? ed by MCC). MCC and MNC together identify a PLMN. Refer to ITU-T E. 212 [129] for MNC usage. The MNC may be two or three digits in length. Common practice is that, within a country (as identi? d by MCC), all MNCs are either two or three digits. †¢ mobile subscriber identi? cation number (MSIN) – the MSIN is the subscriber identi? er within a PLMN. The IMSI is reported to the SCP during CAMEL service invocation. The IMSI may be needed, for example, when identifying a country; countries in North America have equal country code (country code = 1), but different MCC (e. g. Canada = 303; Mexico = 334). 1. 4. 2 Mobile Station Integrated Services Digital Network Number (MSISDN Number) The MSISDN is used to identify the subscriber when, among other things, establishing a call to that subscriber or sending an SMS to that subscriber.Hence, the MSISDN is used for routing purposes. Figure 1. 5 shows the structure of the MSISDN. †¢ co untry code (CC) – the CC identi? es the country or group of countries of the subscriber; †¢ national destination code (NDC) – each PLMN in a country has one or more NDCs allocated to it; the NDC may be used to route a call to the appropriate network; †¢ subscriber number (SN) – the SN identi? es the subscriber within the number plan of a PLMN. CC NDC SN 1, 2 or 3 digits Maximum 15 digits Figure 1. 5 Structure of the MSISDN 6 CAMEL: Intelligent Networks for the GSM, GPRS and UMTS Network IMEITAC 6 digits FAC 2 digits FAC 2 digits SNR 6 digits SNR 6 digits spare 1 digit IMEISV TAC 6 digits SV 2 digits Figure 1. 6 Structure of IMEI and IMEISV The MSISDN is not stored on the subscriber’s SIM card and is normally not available in the MS. 2 The MSISDN is provisioned in the HLR, as part of the subscriber’s pro? le, and is sent to MSC during registration. The MSISDN is also reported to SCP when a CAMEL service is invoked. One subscriber may have multiple MSISDNs. These MSISDNs are provisioned in the HLR. At any one moment, only a single MSISDN is available in the MSC/VLR for the subscriber. . 4. 3 International Mobile Equipment Identi? er The international mobile equipment identi? er (IMEI) is used to identify the ME [or user equipment (UE) in UMTS network]. Each ME has a unique IMEI. The IMEI is hard-coded in the ME and cannot be modi? ed. Figure 1. 6 shows the structure of the IMEI. The IMEI is not used for routing or subscriber identi? cation. Refer to GSM TS 03. 03 [27] for the type approval code (TAC), ? nal assembly code (FAC) and serial number (SNR). The software version (SV) may be included in the IMEI (‘IMEISV’) to indicate the version of software embedded in the ME.The IMEI is always encoded as an eight-octet string. As from CAMEL Phase 4, the IMEI(SV) may be reported to the SCP. 1. 4. 4 Mobile Station Roaming Number The mobile station roaming number (MSRN) is used in the GSM network for routing a cal l to a MS. The need for the MSRN stems from the fact that the MSISDN identi? es a subscriber, but not the current location of that subscriber in a telecommunications network. The MSRN is allocated to a subscriber during MT call handling and is released when the call to that subscriber is established. Each MSC in a PLMN has a (limited) range of MSRNs allocated to it.An MSRN may be allocated to any subscriber registered in that MSC. The MSRN has the form of an E. 164 number and can be used by the GMSC for establishing a call to a GSM subscriber. An MSRN is part of a GSM operator’s number plan. The MSRN indicates the GSM network a subscriber is registered in, but not the GSM network the subscriber belongs to. Figure 1. 7 shows how the MSRN is used for call routing. The MSRN is not meant for call initiation. GSM operators may con? gure their MSC such that subscribers cannot dial numbers that fall within the MSRN range of that operator. 1. 5 Basic ServicesAll activities that may b e done in the GSM network, such as establishing a voice call, establishing a data call, sending a short message, etc. , are classi? ed as basic services. In order for a subscriber to use a GSM basic service, she must have a subscription to that service. 3 The handling of a basic 2 GSM subscribers may program their MSISDN into the phone; this has, however, no signi? cance for the network. 3 Exceptions are Tele Service 12 (emergency call establishment) and Tele Service 23 (Cell Broadcast). Subscribers do not need a subscription to these Tele Services to use them.Introduction to GSM Networks 7 return MSRN request MSRN HLR VMSC MSRN GMSC incoming call MSISDN Figure 1. 7 Usage of MSRN during call establishment to a GSM subscriber service is fully standardized. Hence, a subscriber may use a basic service in any GSM network she roams to, provided that that basic service is supported in that network. The HLR will send a list of subscribed basic services to the MSC/VLR, during registration. When a GSM subscriber initiates a call, the MS supplies the serving MSC with a set of parameters describing the circuitswitched connection that is requested.These parameters are the bearer capability (BC), low-layer compatibility (LLC) and high-layer compatibility (HLC), as will be described below. The MSC uses the BC, LLC and HLC to derive the basic service for this call. The rules for deriving the basic service from LLC, HLC and BC are speci? ed in GSM TS 09. 07 [55]. The MSC then checks whether the subscriber has a subscription to the requested basic service, i. e. whether the subscription data in the VLR contains that basic service. If the service is not subscribed to, then the MSC disallows the call. The basic service is not transported over ISUP.When a CAMEL service is invoked, the MSC reports the requested basic service to the SCP. The SCP may use the indication of the requested basic service for call service processing. Examples include: †¢ video calls may be charged at a higher rate than speech calls; †¢ for data calls and fax calls, the CAMEL service shall not play any announcements or tones. Basic services are divided into two groups: tele services and bearer services. 1. 5. 1 Tele Services Table 1. 1 provides an overview of the available tele services (TS); see also GSM TS 02. 03 [3]. 1. 5. 2 Bearer Services Table 1. provides an overview of the available bearer services (BS). The two bearer service groups are sub-divided into a variety of bearer services with different characteristics. Refer to GSM TS 02. 02 [2]. 1. 5. 3 Circuit Bearer Description Bearer capability, low-layer compatibility and high-layer compatibility are descriptors of a circuitswitched (CS) connection. When a GSM subscriber initiates a call, the BC, LLC and HLC are transported from MS to MSC over DTAP. The MSC includes the parameters in the ISUP signal to the destination. These parameters are also reported to the SCP during CAMEL service invocation.That enables a CAMEL service to adapt the service logic processing to the type of call. Figure 1. 8 shows the relation between LLC, HLC and BC on the DTAP and the corresponding parameters on ISUP. 8 CAMEL: Intelligent Networks for the GSM, GPRS and UMTS Network Table 1. 1 Tele service 11 12 Tele services Description Telephony Emergency calls Comment This TS represents the normal speech call The emergency call uses the characteristics of telephony (TS11), but may be established without subscription and bypasses various checks in the MS and in the MSC This TS relates to receiving an SMS.This TS is not sent to the MSC/VLR.

May be used for synchronous services from 1. 2 to 64 kbit/s.This BS may be used, amongst other things, for multimedia services such as video telephony. 4 DTAP (GSM TS 04. 08) Low layer compatibility High layer compatibility Bearer capability MSC ISUP (ITU-T Q. 763) Access transport [low layer compatibility] User teleservice information User service information Figure 1. 8 Transfer of LLC, HLC and BC through DTAP and ISUP †¢ Low-layer compatib ility – the LLC is transported transparently between the calling entity and called entity; it may be used by the respective entities to adapt codecs for interworking purposes.LLC describes mainly characteristics related to the data transfer. 4 3GPP Rel-7 may include a dedicated bearer service for video telephony. Introduction to GSM Networks 9 †¢ High-layer compatibility – the HLC is also transported transparently between the calling entity and called entity; it is used to describe the requested service, such as telephony, Fax, video telephony, etc. †¢ Bearer capability – the BC describes the characteristics of the 64 kbit/s circuit requested for the call. 1. 6 Supplementary ServicesSupplementary services (SS) in GSM are a means of enriching the user experience. An SS may, for example, forward a call in the case of no reply from the called party, bar certain outgoing or incoming calls, show the number of the calling party to the called party, etc. In o rder to use an SS, a GSM user needs a subscription to that SS. The subscription to supplementary services is contained in the HLR and is sent to the MSC/VLR during registration. The supplementary services are fully standardized.A GSM subscriber can therefore use her supplementary services in any GSM network, provided that the network supports these supplementary services, and have the same user experience. Table 1. 3 SS group Line identi? cation GSM supplementary services Supplementary services Calling line identi? cation presentation (CLIP) Calling line identi? cation restriction (CLIR) Connected line presentation (COLP) Connected line restriction (COLR) Calling name presentation (CNAP) Call forwarding – unconditional (CFU) Call forwarding – busy (CFB) Call forwarding – no reply (CFNRY) Call forwarding – not reachable (CFNRC) Call de? ction (CD) Explicit call transfer (ECT) Call waiting (CW) Call hold (CH) Call completion to busy subscriber (CCBS) Multi- call (MC) Multi-party call (MPTY) Closed user group (CUG) Advice of charge – information (AOCI)Advice of charge – charge (AOCC) User-to-user signalling – service 1 (UUS1) User-to-user signalling – service 2 (UUS2) User-to-user signalling – service 3 (UUS3) Barring of all outgoing calls (BAOC) Barring of outgoing international calls (BOIC) Barring of outgoing international calls except to the home country (BOIC-exHc) Barring of all ncoming calls (BAIC) Barring of all incoming calls when roaming (BICROAM) enhanced multi-level precedence and pre-emption (eMLPP) GSM TS 02. 81 [13] Name identi? cation Call forwarding 02. 96 [24] 02. 82 [14], Call offering Call completion 02. 72 [11] 02. 91 [22] 02. 83 [15], 02. 93 [23], 22. 135 [69]a 02. 84 [16] 02. 85 [17] 02. 86 [18] 02. 87 [19] Multi-party Community of interest Charging Additional information transfer Call barring 02. 88 [20] Call priority 2. 67 [10] a For the multi-call service, there is no GSM TS a vailable, but only a 3GPP TS (22. 135). 10 CAMEL: Intelligent Networks for the GSM, GPRS and UMTS Network Supplementary services may be provisioned for an individual basic service or for a group of basic services, e. g. a subscriber may have barring of all outgoing calls for all tele services and all bearer services, except SMS (tele service group 20). Such a subscriber is barred from establishing utgoing calls (except emergency calls), but may still send short messages.Some supplementary services may be activated or deactivated by the user. Examples include call forwarding and call barring. An operator may decide to bar certain subscribers or subscriber groups from modifying their supplementary services. Table 1. 3 shows the Supplementary Services. They are combined in service groups. Subscriptions are per individual Supplementary Service. The right-most column indicates the GSM technical speci? ations (TS) that specify the service requirement for the respective Supplementary Servi ce(s). The chapters on CAMEL Phases 1–4 describe the interaction between CAMEL and the various supplementary services. Not all GSM networks support all supplementary services. Many of the supplementary services in GSM have equivalent supplementary services in ISDN. The ISDN supplementary services are described in ITU-T recommendations. GSM TS 02. 03 [3] describes how the supplementary services may be activated, deactivated and invoked.

All Saints – Retail Environment

My Favourite Retail Environment: All Saints Before you enter the shop, All Saints have set their tone. Headless mannequins hang on chains, enclosed by dark grey walls; the window display at the front of the shop is bleak yet the simple nature portrays the beauty of the garments. The surrounding windows are tinted, therefore you can see out but not in; this gives the shop an exclusive feeling, contributing to the individual style of the clothes and the high price tags.The building is the main feature of All Saints which sets it apart from other high street shops; it’s a converted bank, however it’s been renovated to look and feel like a church, this view is gained from entry as you step through the huge wooden doors. The ceilings are high, the arches, pillars and cornices are incredible, the tiled floor is amazing, and the centre of the store has a beautiful round ceiling mural with a balcony surrounding and a trio of gold, goblet type ornaments.The shop is very gothic i n style and having every wall painted a dark grey colour contributes the styling of the clothes and the mood the shop puts you in; it’s like a fantasy world where the Victorian era meets modern Soho or downtown New York. Lighting in the store consists of spotlights on the ceiling pointing down at each fixture or display of clothing; this provides great contrast to the blandness of the colours and also highlights the garments beauty.The spotlights also contribute to the exclusive, almost celebrity feeling as they transform the store into a kind of set, depicting a story, as would be done in a movie. There is a hanging cruciform, created from very bright, stark naked bulbs. This creates a very artistic and creative view and a rock ‘n’ roll feel within the store, allowing the consumer to really understand the innovative and conceptual brand they are purchasing from.The theme of crosses is continued throughout the store and also features on the giant iron crest outsi de the store. The fixtures on the wall are created to be in the shape of a cross and the ends of each arm have a small cross logo. The fixtures are like scaffolding and the display cabinets are giant old wooden tables or big heavy draws and cupboards with huge locks and chains. The displays are incredible with huge butcher style hooks, warehouse style chains and metal, old head neck dummies ripping at the seams and skull candles.The store has depressive modern music playing in a relaxed manner, contributing to the contemporary feel and making the shopping experience more pleasant. There is no ‘perfumed’ smell to the store; yet it has a kind of musk which smells like old vs new. All Saints’ staff is incredibly attentive and great at selling in a non-pushy manner. Overall the store is very open plan; the distressed feel and glamour meets grunge cool is inspiring and that is what makes ‘All Saints’ my favourite retail environment.

Single Parenthood: Literature Review

Single Parenthood: Literature Review2 This paper will look at the different research that has already been conducted on single parenthood. Possible research topics could be how single-parent families differ in their structure or financially, in contrast to households with two parents. Articles may also discuss the impact of single parent households on children, in terms of psychological impact, academic results, social and financial standings using statistics found in their research. By looking at articles done through American and Canadian research, it can be determined what research is missing, what the articles lack and possible suggestions to improve the substance of the materials listed. Economic Viewpoint In each article , different points were made about the financial hardships that children from single-parent households may experience and how it was much more likely they would experience them in comparison to children raised in a household with two parents. Lisa Calderwood, from London University’s Institute of Education, says, â€Å"Living apart from natural fathers can be associated with poverty and negative outcomes for children. †(Calderwood, 2010). Though not all single-parents are mothers, but Tim Casey, a senior staff attorney at Legal Momentum,( the U. S. ’ oldest organization advocating on behalf of the legal rights of women and girls. )â€Å"Employment isn’t keeping U. S. ingle parents — more than 80 percent of whom are single mothers — out of poverty. † (Casey, 2012). Here it states that not only are the majority of single parents single mothers, but that the income provided to these mothers is generally still not enough to keep them above the poverty line even though, â€Å"single mothers in the U. S. are employed more hours and yet have much higher poverty rates than their peers in other high-income countries. †(Casey, 2012). Single Parenthood: Literature Review 3 Paul Amato, a Professor of Sociology and Demography at The Pennsylvania State University, makes a good point saying due to lack of funds, â€Å"It is difficult for poor single parents to afford the books, home computers, and private lessons that make it easier for their children to succeed in school. †(Amato, 2005). This is a direct linkage with the academic success of children from single-parent families, which will be discussed later in the essay. Amato makes several good points, also saying, â€Å"they cannot afford clothes, shoes, cell phones, and other consumer goods that give their children status among their peers. (2005) Again this is in direct correlation with self-esteem issues that are more common in children raised by single parents. â€Å"Consistent with these observations, many studies have shown that economic resources explain some of the differences in well-being between children with single parents and those with continuously married parents. †(Amato, 2005). Amato makes the observation that many differences between children raised in single-parent households versus children raised with both parents can be explained by the financial difference brought on by a single income. An article stating that â€Å"Children raised by single mothers are twice as likely to misbehave as those born into traditional two-parent families† , (Paton, 2010), also says that â€Å"studies have found children raised by lone mothers are likely to have less economic security†(Calderwood, 2010)which the article implies influences the behaviour of the child raised in said type of household here: â€Å"parental qualifications and household income had a major effect on children’s behaviour at a young age, which could have â€Å"damaging long-term consequences. After looking at the findings from the different sources, it can be said that it is a fact that single-parent households are worse off financially than households with both parents. This is not only for the parents taking care of their children, but for the academic and social development of the children as stated by Amato (2005). Single Parenthood: Literature Review4 Academic Viewpoint Academically, the studies provide information which states that children from single-parent families do worse academically than those raised by both parents. They are twice as likely to drop out of high school, 2. 5 times as likely to become teen mothers, and 1. 4 times as likely to be idle. † (McLanahan , 2001). Here, Sara McLanahan states that studies have shown that children raised by single parents are more likely to drop out of high school, more likely to become teen parents and more likely to be out of school and without a job. As mentioned earlier by Paul Amato (2005), children raised by single parents cannot afford many things that could greatly benefit them in school such as â€Å"books, home computers, and private lessons. † (Amato, 2005). Paul Amato also states â€Å"In a meta-analysis of sixty-three studies of non-resident fathers and their children, Joan Gilbreth and I found that children had higher academic achievement when non-resident fathers were closely involved in their lives. † (Gilbreth & Amato, 2005). In her article, Sara McLanahan says that family disruption is not the same in all families and risk of failure in school varies among different American nationalities: â€Å"Family disruption increases the risk of school failure by 24 percentage points among Hispanics, 17 percentage points among whites, and 13 percentage points among blacks. (McLanahan, 2001). This is a pattern that is also consistent when it comes to dropping out. â€Å"Behavioural problems were less likely among children living in families with higher levels of parental qualifications. † (Calderwood, 2010) Here, Lisa Calderwood discusses behavioural problems among children raised in single-parent families, especially when it c omes to academics and found that these types of issues were more frequent in children raised by a lone parent. Single Parenthood: Literature Review5 In a chart from the National Study of Adolescent Health (1995), statistics can still show how there is a visible difference in the patterns of children raised by a lone parent, versus children raised by two. Nineteen percent of children raised by two parents had repeated a grade, compared to 30 percent of those raised by a single parent had repeated a grade, (1995). The chart shows this, as well as other categories such as, violence, delinquency, suspended, attended therapy, had smoked in the past month, attempted suicide and had thoughts of suicide. In each of the categories, the percentage of children who had done these things from a single parent household, was consistently higher than the percentages of those raised by both parents. (National Study of Adolescent Health , 1995). Emotional Nina Parry-Langdon , the author of a report done by the Department for Health and The Scottish Government, finds that â€Å"Children from broken homes are almost five times more likely to develop emotional problems than those living with both parents. †(Parry-Langdon, 2008). She specifies further to say that, â€Å"Children and young people in households of ‘reconstituted' families, particularly where there were step-children, were more likely to develop conduct disorder as were those in families which had two parents at Time 1 and one parent at Time 2. † (2008). It is important to realize that not all children that are raised by single parents, have never been raised by two parents. Here Nina points out that distress in children raised in blended families, is similar to that of children who have been through a parent’s divorce. After interviewing 5,364 children aged between five and 16 in 2004 and again last year, the researchers found that 3 per cent had developed problems over that time. †(Parry-Langdon, 2008). Again, this article makes a point to mention how quickly being Single Parenthood: Literature Review6 raised in a single-parent family can take its toll, in this case, in as little as three years’ time before con duction their second round of interviewing. From Paul Amato’s article, he states that â€Å"Interviews with children reveal that losing contact with fathers is one of the most painful outcomes of divorce. † (Amato, 2005). This shows that children are obviously impacted by the loss of contact, which can be compared to grief. Also in his article, Amato says that children from single-parent households have more exposure to stress, through many circumstances such as dealing with the financial burden, the inter-parental conflicts and in many cases having to move homes after the separation of parents. (2005) Tying in directly with stress Amato reveals, â€Å"[a study] based on a large sample of twins, found that growing up in a single-parent family predicted depression in adulthood even with genetic resemblance controlled statistically. †(Amato, 2005). This can partly be credited due to the high exposure to stress, stated above. He concludes by saying, â€Å"evidence strongly suggests that growing up without two biological parents in the home increases children's risk of a variety of cognitive, emotional, and social problems. † (Amato, 2005). In conclusion, after viewing these articles, there is much evidence to support the thesis that children from single parent households suffer in comparison to households in which both parents reside with their children. Further topics that should be considered are geographical patterns, as it seemed most of the research was focused at the United States. Another suggestion for the articles would be to gather more personal information from children of single-parent households, rather than cold statistics. The statistics make it easy to dismiss the reason behind the negative results, as opposed to hearing from children who are being raised by single parents to hear how they feel and why they feel they are suffering in certain aspects. Single Parenthood: Literature Review8 The articles did a good job at looking at the different categories including, financial, academic, and emotional issues that stem from single parenting. Out of the articles, Paul Amato (2005) and Sara McLanahan ( 2001). Research available from reputable sources on the topic of single parenthood is limited and its importance as an issue in North American society is diminished as ‘normal’, despite its serious impact shown in said articles.

Retirement Age Assignment Example | Topics and Well Written Essays - 1250 words

Retirement Age - Assignment Example Raising the retirement age to 65 is not favorable especially I this current situation of the economy where job opportunities are scarce. This denies the young energetic generations the opportunities to enter the job market earlier enough. Older people should retire and pave way for youths. Moreover, employment currently dictates that anybody eligible to retire should go ahead and do so. Currently, the economy dictates the age at which one wishes to retire; this is because the economy does not match the savings of workers. People are pessimistic about their little savings that cannot sustain them after the retirement of 65. Workers, therefore, should be allowed to stay working in order to meet their demands pertaining their social security. Employers too determine the age retirement of employees, especially in the private sector. This comes in situations whereby a worker can decide to seek earlier retirement basing on the working conditions and. In this case, the employer should allow the employee to do so and therefore this call for employers to consider the employee’s increments. A person should, therefore, be allowed to express his or her rights but many at times employers take advantage of such situations to lay off these workers and they even deny workers their returns. Basing on this argument retirement age should not be enforced rather people should be allowed to enjoy. People should not be forced to retire at age 65 since, under the employment law, there is no exact age of employing professionals.

Audience analysis memo Research Paper Example | Topics and Well Written Essays - 750 words

Audience analysis memo - Research Paper Example As such, the website has to be keen to address the needs of even those with no prior knowledge on human health services. This target audience encompasses adults from all cultural, professional and educational backgrounds, regardless of their gender. On the other hand, Wikipedia seems to target scholars, professionals and researchers. It is more in-depth in content and would only appeal to adults with adequate background education on lung cancer, seeking intensive understanding of lung cancer. These could be scholars or professionals in healthcare science, irrespective of their gender or cultural background. In the same way, the websites target different secondary audiences. HHS seems to secondarily appeal to researchers and scholars seeking to get a general overview and introduction to the concept of lung cancer. It gives a guide on the information available to the public on the subject. Wikipedia secondarily targets people from other professions other than healthcare seeking to have general knowledge on the subject. Such persons should have some advanced education to make sense of the information shared. i. Graphical representation: HHS uses warm pictures of fruits and happy people to appeal to the general public. It is perhaps postulated that exhibiting happiness would be more attractive. For Wikipedia, the objective of educating its scholarly audience makes it use real images of lungs which would appeal more to its audience seeking to understand the action of cancer on lungs. The use of charts also provides researchers with a clear understanding of useful statistics on lung cancer. ii. Formality of styles: With HHS targeting a lesser educated audience seeking for basic information on lung cancer, the informal style works effectively. The informality not only involves use of bullet points but also use of simpler phrases in place of technical terminologies. For example,

Reasons that Relationships Fail Essay Example | Topics and Well Written Essays - 750 words

Reasons that Relationships Fail - Essay Example Any union that does not propagate trust as its core value is definitely standing on a shaky foundation. A successful and happy relationship should be predicated on trust, otherwise the union will be punctuated by countless second-guessing, incessant arguing, and an overall unhealthy vibe. Distrust is fueled by insecurity and immaturity, hence one should be hesitant in plunging into a committed relationship if there are any warning signs at all during the dating process. Have you ever seen one of those Catch-22 couples who keep on pining about a "lack of communication" Its always either one talks too much or one's opinions are constantly ignored. Ironically, these are the types of couples who do a lot of "talking", and yet there is no real communication. Given the intricacies of relationships, this is a skill that is acquired over time through trial and error. In a utopian world, the level of communication should increase the longer the relationship lasts. Unfortunately, this is easier said than done, and there are relationships where couples just "tune out" after a certain number of years. It is said that familiarity breeds contempt, and when contempt is present complacency is not far behind. When a relationship reaches a point where there is no longer any dynamism and most days lean toward the mundane, this is a key indicator that the relationship is headed downhill and is oftentimes a direct result of poor communication between the two parties. T he relationship would be dying a slow death, and the tough part is that most couples would never really realize the quagmire that they are in until it is way too late. Capping off the holy trinity of relationship must-haves is the need for understanding. As much of an acquired skill as an intrinsic personality trait, no relationship would possess any long term viability if there is no semblance of this integral trait. As it is inevitable that there would be the obligatory speed bumps along the way, recognizing the need for understanding shows that a couple is willing to rise above the petty niceties and is more focused on the long term. While not necessarily the easiest thing in the world to do, it is a concept that needs to be exercised with significant regularity in order to avoid failure. To conclude, it is glaringly apparent that a lack of trust ,communication, and understanding in a relationship are tantamount to a virtual death sentence, as these are two integral components in the dynamic that need to work in full synergy to be effective. Trust issues, while hinging on other factors such as fidelity and experience, can still be negated if a couple could communicate properly. Likewise, well-meaning efforts to communicate will mostly be misconstrued and taken aversely if there is no existing framework of trust, which in turn fuels the level of understanding in the relationship. This is easier said than done though, and would take considerable initiative and force of will to effectively implement. There is also this other intangible that may work in case all else fails though- its that something called "love". It's always a handy thing to have, specially in a relationship

Management Structure Essay Example | Topics and Well Written Essays - 2500 words

Management Structure - Essay Example Within any organization, the structure and management approaches needs to change in accordance with global changes and requirements and despite several changes, since the World War, companies have failed to meet the demands of the changing world economy. According to Bartlett and Ghoshal (1995) companies seem to have become fossilized and unable to adapt to slower growth so there is much instability in the market. Cost reduction programs tend to provide only short term relief, to the markets and companies so different business and organizational strategies are required to focus on long term gains and benefits to bring about growth and organizational stability. Successful companies like GE, ABB and Toyota seem to have rejected the principles of multi divisional enterprising according to Bartlett and Ghoshal and these companies employ an emerging management model which is not a new organizational structure but brings out a set of management processes and new roles and tasks for managers at different levels. Within any organization, the changes in the managerial structure are based on the core processes of entrepreneurial or encouraging initiatives, integrative and leveraging competence, renewal as in managing, rationalization and revi talization and a new management approach (Bartlett and Ghoshal, 1995). ... l typology of multinational companies or MNCs tend to show a global, multidomestic and transnational aspects of interdependence and local responsiveness. The relationship between local and global corporate social responsibility with international organizational strategy shows that the strategic logic of Bartlett and Ghoshal could be applied to the realm of corporate social responsibility and multinational firms tend to respond to pressures for integration and responsiveness (Husted and Allen, 2006). Multinational firms tend to replicate the product market organizational strategy in the management of corporate social responsibility and these alternative approaches are also followed by MNEs. Institutional pressures, strategic analysis of social issues and stakeholders tend to guide decision making in CSR. Management of multinational enterprises is thus largely dependent on the strategies in management and corporate social responsibility, the analysis of social issues, the human resourc e management approach, and shows the implications of marketing management and public policy. Harzing (2000) used data from 166 subsidiaries of 37 MNCs in 9 countries and show how the MNCs tend to differ in aspects of interdependence and local responsiveness. International management assumes the existence of different types of MNCs that are polycentric, ethnocentric, geocentric, global as well as transnational. Multinational organizations are complex and manageable with a number of related characteristics and a typology for MNCs could help in explaining the functioning of such companies. The lack of conceptual integration and empirical corroboration in international business and management could be corrected with the reinforcing characteristics of MNCs. MNCs that bring about a balance

Legal theory- law is, by its nature, a moral enterprise discuss Essay

Legal theory- law is, by its nature, a moral enterprise discuss - Essay Example The value system their codes represent, although enforced by the elite or recognised by the mainstream, are all quite frequently untruthful.2 We thus admire individuals who, for the sake of morality, have endangered their lives in defiance. Inopportunely, a good deal of what they declare in their own justification is difficult to believe. The idea of Aquinas of higher law can function as a point of comparison. He argued that the process of promulgation is fundamental to law, that a law not disseminated by a source is impossible.3 This means that a higher law has a source, which is its promulgator. This particular promulgator cannot be simply a mortal—not if the law under consideration is better and greater than all codes transmitted by humans.4 God is the promulgator, the law He disseminates perpetual. The natural law, which takes part in the timeless law, is a thing that can be understood by mortals naturally.5Therefore, law is naturally moral. When laws bestow guardianship of minor children to the parent who shows the most potential to further the wellbeing and security of the child, extradite those accused of moral turpitude, they obviously oblige judges to resolve cases morally throughout their legal decision makings.6 Similarly, when constitutions oblige judges to re-examine laws to discern whether they give the procedure that is due individuals, respect the rights of citizens to free speech, freedom from unjustified searches and arrests, freedom to exercise any religion, and others, they oblige judges to make legal decisions founded on moral codes.7 Likewise, once the common law raises tort accountability on whether a person behaved rationally, or once law defends what would otherwise be unlawful behaviour by symmetry of evils justification, judges should resolve cases morally in order to reach legal resolutions.8 Such clear integration of morality by the evident law raises issues for some

Madonna's Voyage to the iWorld Term Paper Example | Topics and Well Written Essays - 3500 words

Madonna's Voyage to the iWorld - Term Paper Example Music and technology have always gone hand-in-hand. As far as 1877, when the voice was first recorded with the inventions of the phonograph and graphophone, the music industry has already been assisted and improved by what innovation has to offer. Given that Madonna’s rise to stardom happened in the 80s, this is also where this paper will begin to trace the chronology of the technological development in the music industry and how Madonna figured out in all of them. By the end of the 1970s, music sales drop and various record companies start campaigns within the industry to restrain or even eliminate home taping. However, in 1979, cassette popularity skyrocketed with the launch of the Sony Walkman. This introduction corresponds to the upgrading of the sound quality of the cassette. Instantly, the cassette tape became the sole format that can be used in your home, carried in your pocket and played in your vehicle. The Recording Industry Association of America, which is the lobby ing and trade organization of the record industry, constantly fought for taxes placed on blank tapes up until the 1980s. Eventually, legislators gave the music labels a part of the sale of each blank tape. In 1978, Sony and Philips revealed their proposal to collaborate and produce an identical format for the Compact Disc. Record labels then revealed, in 1982, a global standard that guarantees that all kinds of CDs will work on every CD player there is. During the same year, â€Å"52nd Street† by Billy Joel was made public in Japan, which is the first ever CD to be launched in the world. Come 1988, the CD exceeded the LP in terms of sales percentage. The 80s was considered the most important period in the history of the recorded audio industry, primarily because of the launch of the Compact Disc. Within three years of the arrival of the compact disc in the industry, one million CD players have already been sold in the electronics market. In comparison, it took more than a dec ade for the manufacturers of colored television to sell one million TVs. Shortly after the introduction of the CD, the Digital Audio Tape (DAT) was launched. Unfortunately, it was met with abrupt opposition from music publishers and composers since they feared the possibility of the piracy, especially because of the almost perfect duplication capability and excellent sound quality of the DAT. From the kick-off, RIAA contends for a tool to be positioned inside the recorder in order to prevent duplication. Even after this tool, which is known as the "serial copy management system†, was placed on all DAT recorders sent to the United States, composers and music publishers continued claiming for fees on every DAT tape or machine sold as a compensation in case of home taping. This dispute led to the lack of support of the format from the record industry. Seeing that the DAT format is not feasible, record labels decided not to produce or market pre-recorded DATs. Since there is no pr e-recorded tape, no one will buy a recorder. Ultimately, since there are no sales for recorders, a market for pre-recorded tape is non-existent. In 1990, the mishmash of the Internet and digital audio started an explosive phenomenon – the creation of the Moving Pictures Experts Group-1 Layer-3 or simply MP3. This is a compressed audio file with a small size but still the same sound quality. This format makes file transfer way easier. Madonna knew well how she can make use of these new technological developments in the music industry to the fullest. The internet also made her popularity easier to enhance and spread out. However, along with advantages are disadvantages brought about by the same technological innovations. A proof of pop superstar Madonna’s awareness of how technology can advance her career is her fight to gain tight and control over a domain name that clearly alludes to her name and makes use of her popularity. The said domain, madonna.com, is actually a pornographic website that is obviously riding with her name’

Does Religion Cause War Essay Example | Topics and Well Written Essays - 500 words

Does Religion Cause War - Essay Example Beliefs are the key word of the definition. When an individual or group has a set of religious beliefs, these beliefs are their life. Religious beliefs are the main component reflecting decisions that one may make. This means that religious beliefs do not cause war but may influence decisions made after a war has already begun. This can raise argument but truth has shown that most war has begun as a result of territory and possessions and not solely because of religion. Religion regarding beliefs has been an issue of war since creation. Every individual practices some form of religion like Christianity, Judaism, or Atheism. Each form of religion is similar in the sense that the belief is a religion and a way of life. Each religion is also quite different. Many like those in the Christian religion are persecuted for their religious beliefs and cannot be caught acting in a Christian manner. The persecution creates a war in the life of the Christian. They must choose between honoring th eir beliefs and being persecuted. The United States, according to a poll by ABC news consist of 83% Christians. This may be because Christianity is so well tolerated in America and Christians can freely practice Christianity. In other areas of the world Christianity is not accepted and has been known to cause war. This war is more so between the Christian and Muslim communities.

Responsibilities of parenthood Essay Example | Topics and Well Written Essays - 750 words

Responsibilities of parenthood - Essay Example And all of the above values and etiquettes are well inculcated by kids during common meal times. Thus, importance of having meal (and more preferably "dinner" because of its end of the day aura) together as a whole family is quite beneficial for children in terms of nutritional richness of food provided and the family conversation at the dining table. As cited from Rocketts article [1]: "Family dinner has been identified as a foundation of healthful food choices, possibly because of the higher quality of food served and the family conversations at the dinner table about healthful eating."[1] Family dinner has been from historical point of view important for that "special" interaction between its members that makes the bond between them stronger and everlasting in times of distress or threat. From the children's point of view, family dinners are important to understand the family values as well as other family members. meals together send the message that citizenship in a family entails certain standards beyond individual whims. This is where a family builds its identity and culture. Legends are passed down, jokes rendered, eventually the wider world examined through the lens of a family's values. In addition, younger kids pick up vocabulary and a sense of how conversation is structured [4]. The meal time ritual is important for both its social a... There are other benefits of taking the last meal of the day together, as explained; family dinner has opposite effect on weight gaining ability of adolescent children [1]. The direct relation is still under research (as of when the article was written), but taking a meal with family ensures a healthy and appropriate amount of meal goes inside children and adequate eating habits are formed from childhood itself. However, all is not said and done regarding family issues. There are many variables involved in the working of homes and families & every individual has to mould him/herself according to the circumstances prevalent at home. Double-income parents who have evening meetings that take them away from the table, workaholic spouses who don't come home at all, ringing telephone and last-but not the least- those ghastly memories of how children particularly when they are very small, behave when theyre at the table [3]. Historical aspect of family dinner [4] Back in the really olden days, dinner was seldom a ceremonial event for U.S. families. Only the very wealthy had a separate dining room. For most, meals were informal, a kind of rolling refueling; often only the men sat down. Not until the mid--19th century did the day acquire its middle-class rhythms and rituals; a proper dining room became a Victorian aspiration. When children were 8 or 9, they were allowed to join the adults at the table for instruction in proper etiquette. By the turn of the century, restaurants had appeared to cater to clerical workers, and in time, eating out became a recreational sport. [4]. Family dinner can be a respite from the hectic lives of family members to gather for a meal; it can improve the diet of the

Shay`s Rebellion Essay Example for Free

Shay`s Rebellion Essay The 1787 rebellion was led by Daniel shay. He was not much literate, but he portrayed charismatic character. The â€Å"who`s who† of the day had been labeled a rebel, traitor, and coward. However, those allegations were nothing but distant from the truth. He was a devoted nationalist, and a decent military officer supporting America’s devolution. He had devoted over five years of his life in service of America`s government. In addition, besides devoting his life to a patriotic course, he owned little property under his name and was also an accused person in a lawsuit. He mobilized oppressed citizens, both poor farmers and middle class town folks, who disagreed with the government’s actions during the time. He was able to consolidate a militia of over 2000 men. The militia was armed and willing to burn down Boston. According to miller (71), Jefferson heard of the rebellion while, in France but felt that it would not last long. He though that a little rebellion was okay. The political situation was a mess with a weak government that had limited resources and bottomless depts. As a result, they installed large tax levies on American citizens. The uprising divided America`s population into two with conservatives opting to keep of the war. Its events motivated great political progress. Political Events of the period preceding the rebellion depicted a need for big political changes. Voters expressed distaste in government`s actions by developing preference for new leaders. In 1787, Governor Bowdoin lost elections to John Hancock, whom he had defeated in all previous contentions. The people were determined to get rid of every element of oppressive governance. Sherriff Greenleaf was on the state`s side. He held official capacity in Lancaster and employed all possible resources, with the sole objective of monitoring how people related to the rebellion and stopping growth of the militia group. The rebellion created a situation where General Lincoln rejoined America`s political scene. His contributions were in support of America`s government. Shay`s rebellion against political tyranny,  attracted attention from Alexander Hamilton, George Washington, and James Madison who thought that America needed to setup a new government system. Soon, they would start pursuing the agenda of d elivering a federal government system to the American people. Social America experienced a recession beginning in 1784. The government could not survive without extensive external funding let alone subsidizing public projects. They found that salvation could be achieved by demanding a tax increase. According to smith (6), the taxation levels were not ethical. The government tried to exploit farmers and casual laborers, however; their efforts did not make much difference as such persons initially made less money than tax demands. Therefore; the taxman made demands but did not receive equitable monies. Consequently, persons who failed to comply lost property and others were prosecuted in court. Government also owed to soldier. A currency circulation mess, where circulation did not match national wealth was not corrected by government. This led to further escalation of the already unpleasant situation. Crops did very well; farmers brought much harvest from the farms but attracted low market prices. Most farmers did not meet their tax obligations and soon lost rights to continue farming on their land. The labor industry was also in a chaotic situation. Few jobs were available for grab. What`s more, wages attached to such were not enough to get by on. Technology was not advanced and manufacturing did not take place. According to Humphrey and Richard (2), merchants and the government alike oppressed farmers. The rebellion was successful in inspiring a revision of tax rates. Soon, America`s taxman reviewed tax downwards. Cultural Shay`s rebellion was not supported by the conservative clergy. Racisms increased the disparity between the rich and struggling population. Majority of the rich folks were white while many African Americans were defined by poverty. Christianity was popular though it’s disputable that Christian virtues were followed to the letter, because; it appears that injustice consumed the social, economic, and political scene. Racial segregation created a window for crucifixion of the black community. Conservative clergy believed in superiority of white community, and openly displayed that  African Americans occupy an inferior position relative to whites. Therefore, conservative clergy supported and felt that the system was just in its actions. They did not identify with the rebellion`s cry for change. In conclusion, the rebellion was an eruption after a period of constant economic, political, and cultural oppression. America`s population was divided along social status boundaries, living merchants and professionals on the side of government and farmers and laborers on the resistance side. The militia lost the battle but worn the war. They lost to the state but political figure lenient to Shay`s rebellion ideals assumed office and reduced the economic burden. Tax rates were revised. The period also inspired political revolution and resulted in a new government system. Works cited Humphrey, Thomas J., and Leonard L. Richards. Journal of American History 90.2 (2003): 625.

Processes of Polyadenylation

Processes of Polyadenylation DNA once transcribed into mRNA it is transported to the cytoplasm. All mRNA’s including specific unspliced mRNA precursors contain the poly A tail with histon mRNA as an exception. But once they are transported to the cytoplasm there exist a poly (A) tail shift that is brought about by the degradation by RNases and rebuilding by cytoplasmic poly (A) polymerase. Discovery: James Darnell and his coworkers carried out various experiments to study and understand the process of polyadenylation. To begin with, they concentrated on the isolation of the poly (A) tail from the newly synthesized mRNA of the HeLa cell line using two subtypes of the enzyme RNase. The enzymes were; 1. RNase A which function as nucleases that cut after the pyrimidine nucleotides C and G and 2. RNase T1 which cuts after G nucleotides. Both these enzymes together helped in selection of pure runs of A’s. They then carried out centrifugation to separate the nucleus and cytoplasm to separate them according to their sizes and exposed them to the scintillation counter. The results obtained showed that both peaks of the nucleus and cytoplasm electrophoresed even slower than the 4S-tRNA and 5S-rRNA markers used (size markers). It also confirms the little difference in size that exist between the nuclear and cytoplasmic mRNA poly (A)’s. Position confirmation: To confirm the 3-prime position of the poly (A) tail they subjected mRNA to an enzyme RNase. On complete digestion it yielded one molecule of adenosine and about 200 molecules of AMP. This result also aided in concluding the size of the poly (A) tail to be about 200 nucleotides long but recent advances and studies have confirmed the size of the poly (A) tail to be about 250nt long. Activity of poly (A) polymerase: Furthermore it had to confirmed that the poly A tail hadn’t come from DNA transcription as the DNA doesn’t contain long runs of T’s. Therefore being a post transcription modification it stresses on the activity of the poly (A) polymerase that adds AMP residues one at a time to the mRNA synthesized during the transcription process. This can be confirmed with the use of actinomycin D that inhibits DNA-directed transcription but doesn’t inhibit polyadenylation. Role of the poly (A) tail: 1. Protects mRNA from degradation – Michel Revel and his colleagues studied the same by injecting globin mRNA with and without poly A tail into Xenopus oocyes and measured the rate of its synthesis at various intervals. They found a little difference at first but after 6 hours only the mRNA without the poly (A) tail couldn’t support translation. The simplest explanation they gave regarding the same was that the mRNA with the poly (A) tail had a longer shelf life therefore its protective in nature. 2. Stimulates translation of the attached mRNA- Poly (A)-binding protein (PAB 1) in eukaryotes boost the efficiency of the mRNA translation. This is confirmed by the invitro experiment that contained a capped and poladenylated mRNA excess poly (A) tails. When comparing with the control that lacked the excess poly (A) tails lower rates of translation was observed. This suggested that the free poly (A) tails competed with the poly (A) tails on the mRNA. Another control confirmed that in the absence of the mRNA the transciption rates were very low as it can’t bind to PAB1 efficiently. David Munroe and Allan Jacobson studied the effect of both capping and polyadenylation on the transcription of two synthetic mRNA’s(rabbit ÃŽ ² globin gene-RBG and vesicular stomatitis virus N gene –VSN.N under the influence of phage SP6 promoter) in rabbits reticulocytes. a) Polysome profi les. Munroe and Jacobson mixed  32P-labeled poly(A)1 (blue) and 3H-labeled poly(A)2 (red) mRNA with a  rabbit reticulocyte extract, then separated polysomes from monosomes by sucrose gradient ultracentrifugation. The arrow  denotes the monosome peak; fractions to the left of this peak are  polysomes, and one can see the disome, trisome, and even higher  polysome peaks. The poly(A)1 mRNA is clearly better at associating  mRNA stability and translatability. The Basic Mechanism: Polyadenylation is assumed to occur either at the 3à ¡Ã‚ ¿Ã‚ ½-end of the primary transcript synthesized or at the polyadenylation site upsteam to the last coding site of the transcript. But polyadenylation begins even before the transcripts is synthesized as it involves a pre-transcriptional step of clipping of mRNA and then adding poly(A) tail to the newly exposed 3à ¡Ã‚ ¿Ã‚ ½-end. Thus the RNA polymerase can still be functioning as somewhere upstream the polyadenylation apparatus has already located a signal which can cut the mRNA upstream and polyadenylate it. Nevins and Darnell eliminated the first hypothesis by creating hybrids of radioactive RNA made in cells late in infection to DNA fragments of the major late region. If transcription halted at the first few genes after the first polyadenylation sites then much more transcripts would bind to the 5à ¡Ã‚ ¿Ã‚ ½-end rather than the 3à ¡Ã‚ ¿Ã‚ ½-end of the major late region. But it was seen that the RNA hybridized equally to both the ends confirming that once the transcription of the late gene has begun it runs all the way as there is only one transcription terminator at the end of the gene. Thus this region can be called as a transcription unit due to its ability to be transcribed as a whole though it contains multiple genes. They also went on to confirm the clipping of the mRNA pre translation. Erhard Hofer and James Darnell isolated labeled globin encoding RNA that was induced by dimethyl sulphoxide-DMSO and hybridized it to the ÃŽ ²-globin gene and regions downstream to the gene. They observed hybridization to fragments within the ÃŽ ²-globin gene and upto 500 bp downstream to the polyadenylation site. Thus confirming that transcription terminated about 500 bp beyond the polyadenylation site in both cellular and viral transcripts. Hofer and Darnell isolated nuclei from DMSO-stimulated Friend  erythroleukemia cells and incubated them with [32P]UTP to label  run-on RNA—mostly globin pre-mRNA. Then they hybridized this  labeled RNA to DNA fragments A–F, whose locations and sizes are  given in the diagram at top. The molarities of RNA hybridization to  each fragment are given beneath each, with their standard deviations  (s.d.). In the physical map at top, the exons are in red and the introns  are in yellow. Polyadenylation signals: The polyadenylation signals depends on the kind of cell that is being transcribed. The signaling process of plants and animals also differ. At the DNA level in mammalian cells the 20 bp- ‘AATAAA’ sequence was discovered as the polyadenylation sequence by various molecular biologist in 1981. And at the RNA level, in mammalian and plants cells the ‘AAUAAA’ sequence about 20-nt upstream of their poly (A) is considered as the polyadenylation sequence. Another common variant ‘AUUAAA’ is also 80% efficient as ‘AAUAAA’. The other variants are less efficient and less common. Molly Fitzgerald and Thomas Shenk studied the importance of the RNA polyadenylation site. They created a recombinant SV40 virus with duplicate polyadenylation sequence 240 bp apart and carried out an S1 assay. They then carried out an S1 assay of the 3à ¡Ã‚ ¿Ã‚ ½-end which showed two signals 240 bp apart confirming the activity of both the sites. They then deleted one of the two polyadenylation sites one at a time and carried out the S1 assay again. The inserted polyadenylation site beyond the pre-mRNA couldn’t function if the site within the pre-mRNA was absent. Several other scientist studied this phenomenon and discovered another sequence present immediately downstream to the polyadenylation recognition site that affects polyadenylation. But the difficulty in further discovery of details regarding the same was difficult as this wasn’t a conserved sequence among invertebrates. This region was usually found to be a GU- or U- rich region 20 bp downstream to the polyadenylation recognition site. Anna Gil and Nicholas Proudfoot studied this hypothesis in detail and observed the following results: Added an extra copy of the whole polyadenylation signal upstream and carried out an S1 assay. This cloned DNA showed 90% efficiency. Deleted the 35-bp fragment containing the GU- and U- rich region. Polyadenylation process was hampered which explains its importance. Reconstructed clones containing either a GU- rich or a U- rich region. These clones showed however only 30% efficiency. Clones GU- and U- rich regions by an excess of 5-bp sequence between them. These clones showed only 30% efficiency confiming the importance of the spacing between them. Based on all these manipulations they concluded that for an efficient polyadenylation signal; (a)A polyadenylation recognition motif ‘AAUAAA’ followed by (b)A 23-25-bp GU-rich motif downstream immediately followed by (c) A U- rich motif. POLY (A) POLYMERASE: The poly (A) polymerase (PAP) was discovered by James Manley in 1991. He cloned their genome and discovered two different cDNA’s that had variable 3à ¡Ã‚ ¿Ã‚ ½ends due to two alternative splicing methods giving rise to two different PAP’s (PAP-à Ã¢â‚¬  , PAP-à Ã‚  [the most important], four additional PAP). They differ in the amino acids sequences present at their carboxy termini but the PAB-à Ã‚  consists of consensus sequences that overlap with the known functional sequences of proteins. The genome consists of :1. RNA-binding domain (RBD), 2. Polymerase module (PM), 3. Two nuclear localization signals (NLS-1 and NLS-2), 4. Serine/Threonine-rich regions S/T. Polyadenylation at the amino terminal. The mRNA is polyadenylated before leaving the cytoplasm as well as after entering the cytoplasm. However these two adenylations could be distinguished by Sheiness and Darnell due to their slight difference in size. They confirmed the same by carrying out various assays against the isolated mRNA that was grown in labeled RNA for 48 hours. The nuclear RNA, cytoplasmic RNA, and 5sRNA marker showed peaks as seen in the figure alongside. The major peaks thus obtained are 210 ±20nt and 190 ±20nt for the nuclear and cytoplasmic poly (A) tail respectively. About 50nt RNA’s are present in this broad peak. Maurice Sussman, in 1970 gave the ‘ticketing’ hypothesis which encompasses the theory of each RNA having a ticket to gain entry to the ribosome and further ticket punching everytime it got translated. Thus after a particular limit, it can’t longer undergo protein synthesis which another reason for the shortening of the poly (A) tail. Thus the 3à ¡Ã‚ ¿Ã‚ ½-end shortening of the poly(A) tail clearly depends on the some other factor other than translation or the ticket like some post-transcriptional modification. It has been observed that the poly(A) tail has not only been shortened in the cytoplasm but it also turns over. This inverted poly(A) tail is susceptible to RNase degradation and elongation by the cytoplasmic poly(A) polymerase simultaneously. This continues till the mRNA looses all or almost all of the nuclear poly(A) tail. This happens when its almost time for the demise of the mRNA. Cytoplasmic polyadenylation This process is best studied in Xenopus oocytes. Administration of progesterone to their oocytes cause stimulation of the deadenylation of maternal mRNA’or maternal message. Polyadenylation the actual process: The process involves the recognition of that conserved polyadenylation motif, RNA cleavage and polyadenylation. Pre mRNA cleavage: The proteins responsible for this cleavage are: Shrenk and his colleagues carried out various experiments confirming the importance of these cleavage factors. Cleavage polyadenylation specificity factor (CPSF)- Its one of the most important factors. Its subunit CPSF-73is related to ELAC that cleaves pre-tRNA’s to generate their 3à ¡Ã‚ ¿Ã‚ ½-end. They are known as ÃŽ ²-lactamase superfamily of Zn (as they contain 2 Zn ions at their active site necessary for RNase activity) dependent hydrolases. Cleavage stimulating factor (CSF) – Its one of the most important ones. It bindings to the GU- rich region, together and stably. Cleavage factors (CF à Ã¢â‚¬   and CF à Ã‚ )- The poly (A) polymerase- This immediate coupling is so strong that no cleaved unpolyadenylated RNA’s can be found. The RNA polymerase à Ã‚ (containing the carboxy terminal domain-CTD and its phosphorylation status). Yukata Hirose and James Manley expressed CTD as a fusion protein with glutathionine-s transferase. They then purified the protein by glutathionine affinity chromatography and the phosphorylated and non-phosphorylated forms were exposed to the cleavage assay with adenovirus L3 pre-mRNA. The results obtained confirmed that (a) the activity of CTD is independent of transcription and (b) After incubating the phosphorylated and non-phosphorylated forms of the enzyme along with all the other cleavage factors showed that the phosphorylated forms five times batter cleavage. This can be explained as the phosphorylated form of CTD is present in the polymerase à Ã‚  that carries out transcription. Polyadenylation initiation: Once the pre-mRNA is cleaved using the factors described above its polyadenylation process takes place in two phases. The first initiations phase consists of the slow addition of the first 10 A’s. This phase depends on the ‘AAUAAA’ signal. The second phase is independent of the initial ‘AAUAAA’ signal but it depends on the existing 10 A’s added to the pre-mRNA. This phase involves rapid addition of about 200 or more A’s along the length, thus called elongation. The initiation signal that carries out polyadenylation is none other than the cleavage signal which attracts the cleavage enzyme that specifically recognizes the AAUAAA motif and cuts the RNA 20 nucleotide downstream. This thaught was discarded because as the cleavage enzyme prior to polyadenylation has already cut the downstream GU-rich and U-rich sequence. Thus it’s this 8 nucleotide GU/U-rich sequence post the AAUAAA motif that brings about this adenylation. Marvin Wickens and his colleagues used two parameters (a) a poly (A) polymerase and (b) a specificity factor CPSF that binds to the pre mRNA. Both these factors work well when substrates are in high concentration but the assay carried out was using low substrate concentrations. The figure alongside explains their experiments, Lane 1- shows no polyadenylation by poly (A) polymerase by itself in low concentrations of substrates, Lane 2- shows no polyadenylation as the CPSF alone can’t detect the AAUAAA motif, Lane 3- shows polyadenylation with both factors together and Lane 4- shows that both factors can’t polyadenylate a substrate with an aberrant signal like AAUAAA. But however this dependency is temporary i.e. after the addition of the first 10 nucleotides it enters the elongation phase that’s independent of these two factors. ELONGATION OF POLY (A) TAIL: While studying the fact that the initiation is independent of the CPSF factor, another interesting fact came to be known that a purified poly (A) polymerase could carry out elongation very poorly on its own. Whale further explored this by designing experiments which consisted of purification of the poly (A) polymerase and its polyadenylation capability comparison in various conditions. Purification of the poly (A) polymerase using PAGE gave two fractions – a major 49-kD polypeptide (PAB-à Ã¢â‚¬  ) as well as a minor 70kD polypeptide (PAB-à Ã‚ ). This latter band however was found to have a variable nature and was even absent in some preparations. Whale’s experiments further showed high activity of this 49-kD polypeptide coinciding with high activity of the poly (A) polymerase using a nitrocellulose filter binding assay. He also tested this fraction’s capability of polyadenylation in the presence of the CPSF and poly (A) polymerase and found the same results. He therefore named this fraction as poly (A) binding proteinà Ã‚  (PAB- à Ã‚ ). Thus he confirmed that PAB-à Ã‚  acts like CPSF but binds to poly (A) polymerase instead of the AAUAAA motif on the RNA. Its activity is high only in the elongation phase but is found absent in the initiation phase. He carried out another experiment to find the interdependence of these two factors with their interdependence on the polyadenylation process using the poly (A) polymerase. When either CPSF or PAB-à Ã‚  was added to a solution that contained mRNA and poly (A) polymerase, the polyadenylation process was found to be active. But it showed higher polyadenylation capabilities in presence of both the factors. Thus this whole process can be summarized by the proposed figure below:-

Martin Luther King’s Letter from Birmingham Jail Essay -- Martin Luthe

Martin Luther King’s â€Å"Letter from Birmingham Jail† is an excellent example of an effective argument; it was written in response to an editorial addressing the issue of Negro demonstrations and segregation in Alabama at the time. He writes in a way that makes his argument approachable; he is not attacking his opposition, which consists of eight Alabama clergymen who wrote the editorial. This is illustrated in his opening sentence: â€Å"My dear Fellow Clergymen† (464). King was an activist for civil rights during this time, and came to Alabama to help out his fellow brothers that were facing opposition. He was concerned with the monologue rather than dialogue that was going on during this time in Alabama; where each side would talk about the problem but never get together to negotiate and seek a solution. The clergymen’s editorial along with the unjust circumstances for Negroes at the time in Alabama was King’s driving force in writing this letter from his jail cell, and created an outline of a strong argument for many years to come. I have found through engaging in arguments with friends and in classes that a personal point comes across more clearly when you just present your point of view without condemning the other party. People are more likely to listen to a personal opinion or an opposing view of argument when there is no tension. Also, to the audience the argument becomes more credible when one is not attacking the opposing side. King knows that he is speaking to not only the white clergymen, but to the white moderates on a much larger scale. King addresses these moderates, saying that they are often times the most dangerous of his opposition, for at least the extremists know where they stand. He states: I have r... ... was diminished years ago? We read this because it is commonly said that â€Å"If we do not learn from history, then we are doomed to repeat it.† The racial issues are still not solved today; sexism and prejudices are evident in today’s society. King’s argument includes underlying truths that can be learned by all. Here is a man who was bold for his cause at a time that he could have, and was, killed for his beliefs; he stood up for what he thought was right, even if it was not popular at the time. Overall, King’s argument is still relevant to society and to times today, even if it is not exactly dealing with the same issues on the same level.

Ageism and the Media Essay -- Argumentative Persuasive Topics

Ageism and the Media    Women over forty are constantly being either ignored or belittled in the media. There are countless women in their twenties and early thirties all over television and the movies. In magazines, the models tend to be much younger. Many are under twenty. Model Roxanne Daner is only 17, but her career will be over by the time she's 20. "I'm afraid to get old. I already feel old. I like to tell people that I'm 17, because 17 sounds young and they think that there is so much ahead for you. But 18, it's like there is not that much more - there's really only two more years." (Changing Face of Beauty: Illusions). According to the U.S. Census Bureau, 42% of Americans are fourty and older. In 1999, the Screen Actors Guild reported that only 1 in three roles went to performers over fourty. However, women over fourty fared worse than men of the same age. While 37% of male roles in television and film went to men fourty-years-old and over, only 24% went to women of the same age. 34% of male lead roles went to older men while only 21% went to older female leads. These depictions of older females are far from accurate when compared to the population. Now that's not to say that there's nothing out there - surly there are some additions to the re-runs of the Golden Girls - "the Bridges of Madison County," even older sex symbols like Sean Connery. But nothing commensurate with the size, wealth, and media dedication of the older population. (Starr) Of the top ten network television shows (excluding reality shows and game shows) for March 5-11, 2001; all ten portrayed men over forty while only seven portrayed women over forty. There were twenty-five males and seven females over forty.

Security Monitoring

Security Monitoring Amy Smart CMGT/442 University of Phoenix Online Instructor: James Summerlin April 15,2013 Security Monitoring In this paper we will be discussing security monitoring techniques that can and should be used within an organization to help put together an solid action plan when there is an risk identified. For any business or organization to ensure that they are conducting quality business to their customers as well as achieving their business goals should consider risk management as an huge part of their organization. Security Monitoring ProcessThe organization IT department and e- commerce applications are the ones that conduct security monitoring and measuring. Security monitoring is very important, because it is the process of preventing attacks and responding to threats that could happen in the future. An organizations can prevent small risk from turning into a bigger and more expensive problem by taking preventative steps. The IT department should be monitoring the system at all times and it must be implemented both externally and internally. However the first step each organization should take when starting the monitoring system is to first discuss what a potential risk is.For an organization to truly have an secure system they must determine an list of risk. Businesses and organizations can use security monitoring to ensure both integrity and confidentiality for sensitive information. As well as holding IT administrators responsible for keeping their organizations sensitive and financial assets safe and secure from unwanted eyes. Internal IT and Secure Monitoring Processes The security monitoring activities that should be conducted in an organization with both internal IT payroll, human resources, inventory, general ledger, inventory monitoring.However these internal structures constantly grow and increase revenue and the possible risks are also always growing and increasing. So for an organization to make sure that there information is safe and secure they will have to make sure that they have their network secure. There are an number of tools an business or organization could use to help keep the network secure, but we will only be discussing a few. The first step would be to create an good an strong password. The pros on having an password would be that it helps to protect unwanted users on their computers.However employees could forget the password so the organization would have to decide if that was an problem then they may want to have an only IT members knowing the password. Then we would have to decide which network firewall would work best for their business. The network firewall is very important to have, because it protects the network from unwanted users and can be used from small company networks to large corporate system. Another great tool to use to keep the organization network secure internet filtering software and monitoring tools, which would be used to protect their employers from inappropriate usage from their employees.Lastly vulnerability assessment and penetration testing is an very great tool to use, because any company that does any business online should and needs to perform an regular vulnerability assessment on their network. The next step in keeping all the organization personal and financial information secure would be to set in place an antivirus protection. Antivirus is important to have because it will protect the computer and the information store in it safe from virus that can wreak havoc on your computer and the information store upon it as well.However antivirus cannot do it alone so by also making sure the organization computer are always up-to- date and running properly is another step closer to being fully protected. Some examples of Antivirus software would be Norton, AVG, Shield Deluxe, or Panda Antivirus Pro, and all are very good antivirus software to use to keep their computers safe and secure. Data security is the next step in which an organizati on needs to take to make sure that their whole system is safe and secure from the inside out. Establishing an strong password is the first level of defense to keeping data secure.The next would be to make sure that there is an strong firewall, by having firewalls in place will help to keep the network properly protected from viruses and hackers. Data security is also achieved by having antivirus and anti- malware which is an systems last line of defense if everything else has failed. Having an organizations computer systems up to date and running properly is another great step to keeping their data safe, because if their computer software is not up to date then it won't be able to provide the upmost protection towards their personal data.Performing backups to the external hard drive is the best way to insure that all the data is stored safely. Then lastly is to have their IT department monitor diligently so that they can look for specific information coming out of their network. In conclusion we have discussed the security monitoring activities that should be conducted in an organization with both internal IT payroll, human resources, inventory, general ledger, inventory monitoring. As well as how important each one of these activities are and how they help to monitor and keep their system safe and secure from unwanted eyes.
