Thesis (MPhil)--Stellenbosch University, 2004. / ENGLISH ABSTRACT: The Ministry of Information of Eritrea is basically aimed at providing the society with news, information, education and entertainment. In addition to its service presentation through radio, TV and printed press the Ministry of Information has taken the initiative to present its services in the digital way by publishing a website known as shabait.com. But as the technique is new to the country as well as to the organization, it is to be expected that there will be inaccuracies in the way the website was designed. Hence, evaluating and redesigning shabait.com with the goal of making it informative, attractive and easy to use will be very beneficial to the organization as well as to users of the website. This recently launched website is not very attractive and not successfully directed to its users. Therefore, the main aim of this study is to assess and find the best way of presenting information digitally to the Eritrean society, as well as to anyone interested in finding out about Eritrea through the State owned media website. This study was firstly approached by gathering previously written relevant information from books, journals, and the Internet. In addition to that interviews with concerned people in Eritrea were held to understand the aim, difficulties and challenges of the website. Subsequently the website was assessed according to the evaluation criteria developed, based on the literature review. The evaluation of the website assumed three different approaches of qualitative as well as quantitative types. A usability test with both quantitative and qualitative questions was done through a questionnaire, which was analyzed statistically. A competitive analysis, of qualitative type with two international websites was also made. In order to create a good quality website, it is essential to have clearly specified goals, policies and strategies, and adequate advanced human as well as technological resources, so that it will be easy to overcome the common challenges such as competition, diversity of users, budget constraints, and inadequacy of policy instruments. The findings of the evaluation of shabait.com indicate that the website is not attractive, is user unfriendly, of low content quality as well as with low download speed and, more importantly, was not advertised well. Therefore, shabait.com is not fit to be considered as a sole first hand information provider website for the Eritrean society as well as for anybody who is concerned about Eritrea. At the end of the study recommendations of how the website can be modified to be successful are listed. / AFRIKAANSE OPSOMMING: Die doelwit van die Ministerie van Inligting van Eritrea is om nuus, inligting, opvoeding en vermaak aan die gemeenskap te verskaf. Bykomend tot die radio, TV en die gedrukte media, het die Ministerie van Inligting nou ook besluit om 'n digitale diens te lewer deur middel van 'n webwerf bekend as shabait.com. Aangesien die betrokke tegnieke vir die land sowel as vir die organisasie iets nuuts is, kan daar verwag word dat die ontwerp van die webwerf onakkuraathede sal toon. Dus moet shabait.com evalueer en verbeter word om dit sodoende aantreklik en gebruikersvriendelik te maak; dit sal tot die voordeel strek van die organisasie so wel as die gebruikers. Hierdie jong webwerf is tans nie baie aantreklik of maklik om te gebruik nie. Dus is die doelwit van hierdie studie om die beste wyses te vind om die gemeenskap van Eritrea, sowel as ander belangstellendes, deur middel van 'n webwerf wat deur die staat beheer word, digitaal van inligting te bedien. Relevante geskrewe inligting is bekom deur middel van boeke, joernale en die Internet. Daar is ook onderhoude gevoer met mense betrokke by shabait.com om sodoende die doelwitte, probleme en uitdagings van die webwerf beter te verstaan. Daarna is die webwerf evalueer volgens ontwikkelde kriteria gebaseer op die literatuuroorsig. Vir die evaluasie is drie benaderings gebruik, beide kwalitatief en kwantitatief. 'n Bruikbaarheidstoets is deur middel van 'n vraelys gedoen met kwalitatiewe sowel as kwantitatiewe vrae en die antwoorde is statisties ontleed. Twee internasionale webwerwe is ook ontleed sodat hulle gehalte met dié van shabait.com vergelyk kon word. Om 'n webwerf van goeie gehalte te ontwerp, is dit noodsaaklik om duidelik omskrewe doelwitte, beleide en stategië, asook genoegsaam opgeleide mense en gevorderde tegnologiese hulpbronne te hê sodat die uitdagings soos kompetisie, verskeidenheid van gebruikers, begrotingsbeperkings en swak beleidsinstrumente oorkom kan word. Die bevindinge van die evaluasie van shabait.com toon dat die webwerf onaantreklik en gebruikersonvriendelik is, die inhoud is van swak gehalte, die aflaai spoed is laag en en die werf is nie goed adverteer nie. Daarom is die werf nie geskik om beskou te word as die enigste eerstehandse inligtingsverskaffer webwerf vir die gemeenskap van Eritrea sowel as ander belangstellendes nie. Aan die einde van die studie is daar aanbevelings vir die verbetering van die webwerf.

O modelo descreve esquematicamente cinco etapas de um processo iterativo: análise, conceito, desenvolvimento, protótipo e teste. Para dar suporte ao modelo, foram desenvolvidas oito diretrizes que versam sobre os requisitos e a configuração das técnicas de adaptação. Uma amostra composta por designers aplicou o modelo e diretrizes para o PDIWA durante o desenvolvimento da interface para o web site adaptativo #Diferente todo mundo é# (projeto de pesquisa apoiado pelo CNPq - Edital no 61/2005). Observou-se que o modelo e as diretrizes para o PDIWA propostos nessa tese cumprem o seu papel, pois designers que desconheciam a área de Sistemas Adaptativos foram capazes de desenvolver a interface para uma web adaptativa. This thesis regards the proposal of a model and guidelines for design process of adaptive web interface (PDIWA), they were development to guide and to assist the web interface designer during the design process. The model describes schematically a iterative process with five stages: analysis, concept, development, prototype and test. Eight guidelines about the configuration and requirements of adaptation techniques were established to give support to model. Designers that composed a sample applied the model and guidelines during the development of interface for #Everybody is Different# adaptive web site (research project supported by CNPq - proclamation no 61/2005). The designers that don#t known the Adaptive Systems area, they were capable to develop the interface for adaptive web; thus, it was observed that model and guidelines for PDIWA fulfilled its function.

In addition to discussing the theory and development of existing preservation approaches to cultural landscapes and industrial heritage sites, the study identifies characteristics and values aimed at expanding the framework of historic industrial landscape preservation practice. Using case studies of western hard-rock mining landscapes as the primary examples, the study argues that management strategies based on traditional preservation practices are insufficient for interpreting the complexity of these historic places, and that historic industrial landscape preservation is best served by attending to the range of values and processes associated with the historic landscape and its protection. / Committee in Charge: Robert Z.

Por menor e menos planejado que tenha sido,terá existido um responsável por oferecer caminhos de acesso à informação apresentada. Essa preocupação norteia todo o processo de criação do site e, ao final,estará diluida, permanecendo transparente aos olhos do visitante. Este trabalho pretende pesquisar e refletir sobre como a utilização consciente dos recursos disponíveis, a estruturação da informação e a clara organização do conteúdo, os mecanismos de navegação lógicos e concisos e uma interface transparente e intuitiva facilitam a utilizaçãode um Web site por parte do usuário. Como meio de verificação da aplicabilidade dos conceitos investigados,foi concebido e realizado um Web site corporativo, na forma de estudo de caso, representando a parte prática deste trabalho / Abstract: In the World Wide Web context, each published Web site has an inherent preocupation with the way in which it will be manipulated by the user. Independent of the Web site size and project, there was someone responsible to offer ways for accessing the information presented. This preocupation guides ali the process of a Web site design and at the end it will be dissolved, be coming invisible to the user. This work intends to research and to consider about how the conscient utilization of the available resources, the information structure and clear content organization, the logicand concise navigation systems and the use of a transparent and intuitive interface can result in a better use of the Web site by the user. In order to verify the aplicability of the investigated concepts, a corporative Web site was developed bya practical project based in a case study / Mestrado / Mestre em Multimeios

Dadas as discursividades impulsionadas pela inserção das tecnologias de informação e comunicação (TICs), em particular a Internet, pretendemos observar o funcionamento discursivo do buscador Google, considerando algumas das ferramentas oferecidas por este buscador. Isso posto, realizaremos busca em torno dos significantes Dilma Rousseff e Marina Silva, flagrando o jogo de atualização da memória discursiva sobre esses nomes, sobretudo no período que corresponde a campanha eleitoral de 2010. Para tanto, mobilizaremos os pressupostos conceituais da Análise do Discurso de matriz francesa, sobretudo a partir dos trabalhos de Michel Pêcheux, para interpretar os modos de produção, constituição e circulação do discurso com essa materialidade peculiar, que é o suporte eletrônico. Consideramos que tal materialidade se erige segundo condições de produção que vocifera e dá a ver o caráter rizomático do funcionamento da língua. / Given the discourses driven by the insertion of information and communication technologies (ICTs), especially the Internet, we intend to observe the discursive functioning of the Google search engine, considering some of the tools offered by this search engine. That said, we will carry out search about the significants \"Dilma Rousseff\" and \"Marina Silva\", catching the game of memory discursive about these names, especially in the period corresponding to 2010 election campaign. For this purpose, will mobilize the conceptual assumptions of discourse analysis of the French headquarters, especially since the work of Michel Pecheux, to interpret the modes of production, creation and circulation of discourse peculiar to this materiality, which is the electronic media. We believe that such materiality is elevated under conditions of production that rages to do and gives the character of the rhizomatic functioning of the language.

Binding sites for prolactin have been identified and characterized in a plasma membrane enriched fraction isolated from livers of mature female rats. By chemical and enzymatic analysis the membrane preparation was shown to have slight contamination with nuclei and endoplasmic reticulum, while mitochondria were not detected. Sidedness analysis indicated that the membrane preparation was largely composed of inside-out vesicles. ¹²⁵I-oPRL prepared by the lactoperoxidase method had a specific activity of 40-60 μCi/μg. Competition studies using iodoprolactin indicated that iodination of the hormone did not affect its affinity for the receptor as compared to the native hormone. Binding of ¹²⁵I-oPRL was inhibited by prolactin from various species including ovine, bovine and rat prolactin while bGH, pACTH and AVP had no effect on binding. The binding of 125 I-oPRL was activated by both bivalent and monovalent cations - bivalent cations exerting a greater effect than monovalent cations. In the presence of 10 mM CaCl₂, binding of ¹²⁵I-oPRL was equal to the binding in the presence of the physiological concentration of NaCI. The association of ¹²⁵I-oPRL with the membrane was a time and temperature dependent process, being maximal at 37°. The dissociation of ¹²⁵I-oPRL was time and temperature dependent only with 150 mM NaCl at 37° while at all other temperatures and in the presence of 10 mM CaCl₂ dissociation was not.observed. The binding of ¹²⁵I-oPRL was strongly influenced by pH with an optimum observed at pH 6.5. Receptor activity was destroyed by pronase and phospholipase C, while neuraminidase increased binding. Treatment of the membranes by RNase and DNase did not effect the binding. Binding of ¹²⁵I-oPRL was inhibited by p-chloromercuribenzoic acid, dithiothreitol, and by brief exposure to high temperatures. Scatchard analysis of the binding of ¹²⁵I-oPRL to receptors indicates that prolactin has a high affinity for its receptor / Medicine, Faculty of / Biochemistry and Molecular Biology, Department of / Graduate

This paper structurally estimates a dynamic model of usage behavior and network effects in a social network site using data from MySpace.com. We view a social network as a stock of capital that yields a flow of utilities over time by creating social interactions between the owner and her friends. When one decides to use a social network site, it may have two distinct network effects: (1) one can manage an existing base of friends through social networking and thus prevent depreciation of capital stock (maintenance effect), and (2) one may acquire new friends through social networking, which results in creation of new capital stock (investment effect). Thus, we model social networking as a dynamic process, in which one's current action to use a social network site can influence the evolution of her social network. We found that realtime chat and messaging, features of MySpace.com, positively affect one's usage decision and hence achieve the intended goal of generating site traffic. However, different demographic groups may have idiosyncratic preferences for these features. Based on parameter estimates, we performed counterfactual simulations with the goal of providing managers with ways to enhance firm performance. / text
