Um aspecto fundamental da aceitação pública da energia nuclear é a crença de que os rejeitos radioativos podem ser gerenciados de maneira segura, no intuito de proteger os seres humanos dos possíveis efeitos prejudiciais, tanto nas gerações atuais como nas futuras. Neste sentido, é essencial compreender como as pessoas percebem o risco associado com rejeitos radioativos e quais são os principais fatores que conduzem suas atitudes em relação à eliminação destes. Uma das maneiras para alcançar esse entendimento é através de pesquisas de opinião. Neste estudo, foi proposto um questionário focado na questão da aceitabilidade da energia nuclear e sua associação com a gestão de rejeitos radioativos, cobrindo os seguintes aspectos: atitudes em relação à energia nuclear e aos rejeitos radioativos, credibilidade das instituições e setores responsáveis pela segurança nuclear, identificação dos benefícios percebidos; percepção do risco de determinadas tecnologias e atividades, percepção do risco real, compreensão das reações emocionais e princípio da precaução. Resultados obtidos a partir de uma aplicação piloto do questionário são apresentados e discutidos neste trabalho. / One of the key features for public acceptance of nuclear energy is the belief that radioactive waste can be managed safely, in order to protect human beings from its possible harmful effects in present and future generations. In this sense, it is essential to understand how people perceive the risk associated with radioactive waste and which the main factors driving their attitudes toward its disposal are. One of the ways to achieve this understanding is through opinion polls. In this study, a questionnaire focused on the nuclear energy aceitability issue and its association with radioactive waste management was proposed, covering the following aspects: attitudes towards radioactive waste and nuclear power, credibility on institutions and sectors responsible by the nuclear safety, identification of perceived benefits, risk perception of specific technologies and activities, perception of real risk, emotional reaction comprehension and precautionary principle. Results obtained from a pilot questionnaire application are presented and discussed in this paper.

The Internet represents a unique opportunity for people to interact with each other across time and space, and online communities have existed long before the Internet's solidification in everyday living. There are two inherent challenges that online communities continue to contend with: motivating participation and organizing information. An online community's success or failure rests on the content generated by its users. Specifically, users need to continually participate by contributing new content and organizing existing content for others to be attracted and retained. I propose both participation and organization can be enhanced if users have an explicit awareness of the implicit social network which results from their online interactions. My approach makes this normally ``hidden" social network visible and shows users that these intangible relations have an impact on satisfying their information needs and vice versa. That is, users can more readily situate their information needs within social processes, understanding that the value of information they receive and give is influenced and has influence on the mostly incidental relations they have formed with others. First, I describe how to model a social network within an online discussion forum and visualize the subsequent relationships in a way that motivates participation. Second, I show that social networks can also be modeled to generate recommendations of information items and that, through an interactive visualization, users can make direct adjustments to the model in order to improve their personal recommendations. I conclude that these modeling and visualization techniques are beneficial to online communities as their social capital is enhanced by "weaving" users more tightly together.

This research attempts to find out the possible reasons which affect to the polling supports of pan-blue and pan-green¡¦s presidential candidates by first-order autoregressive model since May 20th 2000 to March 22nd 2008. We explore the effect of these factors and how the factors to affect the degree of both candidates¡¦ supports. We try to explain the fluctuating of both sides¡¦ degree. To exploring the change of the polling supports and degree, this research collects many significant events during the said period. We view the degree of each category¡¦s effect by sorting out government¡¦s policy, economy, ideologies of independence and unification, the personal issues of candidates, parties¡¦ issue and others to explain the reasons of polling supports¡¦ change in addition I add the effect of media organ, candidates nominating or not, the difference of each election, and the time effect. From the results of this research, the effect of media positions for polling outcomes is not significant, but the candidates nominating or not and the difference of each election affect to pan-blue¡¦s supports and both sides¡¦ degree. Besides, the issue of ideologies of independence and unification influences to pan-blue and pan-green¡¦s candidates, but the candidates personal issues affects the change of the both sides¡¦ degree. When the events of government policy and ideologies of independence and unification are happened more nearly at the polling time, the effect to the change of the polling supports will be greater.

The result of this bachelor thesis is a comparison between three different network devices on how many resources that is used on them when utilizing SNMPv1 and SNMPv2c polls and traps. The devices tested are an old Cisco router, a modern Juniper gateway and a Linux server. The experiments conducted prove that SNMP does not utilize the network devices resources to a point that it becomes an issue for the performance. These tests are done to ensure that SNMP do not use up to many resources on the infrastructure which would decrease the functionality and performance of the network. This study shows whether or not SNMP monitoring is a problem for the enterprise network / Resultatet utav detta kandidatexamensarbete är en jämförelse mellan tre olika nätverksenheter och hur mycket prestanda som utnyttjas när SNMPv1 och SNMPv2c poll och trap används på enheterna. Enheterna som testerna utförs på är en gammal Cisco router, en modern Juniper gateway och en Linux server. Testerna visar att SNMP inte använder såpass mycket utav enheternas resurser att det påverkar prestandan på dessa enheter. Dessa tester görs för att försäkra oss om att SNMP inte tar upp så mycket prestanda på näverksenheterna att funktionaliteten och prestandan minskar. Detta kandidatexamensarbete visar huruvida SNMP övervakning är ett problem för nätverksenheter eller inte.

A new phenomenon on the Internet is the online audience response. Mentimeter is a web-based tool where you can create online polls. The users can then cast a vote and the result is shown in real time. We want to test the information visualization in Mentimeter and we base our hypothesis, that a better graph design is possible, on the work of Edward Tufte and Stephen Few. Edward Tufte is an emeritus at Yale University, where he held courses in statistical evidence and information design and has created theories about how visual information should be designed. Stephen Few is a known information designer and he has based a lot of his theories on the work of Tufte. We compare Tufte and Fews design principles against the Mentimeter tool with user testing. We can see that Tufte and Fews theories still stand strong when it comes to the comparisment with Mentimeter and that a redesign of their graphs could raise the quality and the user experience of the tool. But Mentimeter is also a tool that functions the way it is supposed to.

This thesis approaches the theoretical concepts of public opinion, its history and origins of public opinion research in the Czechoslovak Republic and abroad. It describes the circumstances of the creation, operation and termination of the Czechoslovak Institute for Public Opinion Research, which was established under the leadership of Josef Kopta and came under the I. Department of the Ministry of Information. More particularly provides a detailed view of The Veřejné mínění Journal, which was published between 1946 and 1948 and the publisher was the institute. Among the personalities associated with the institute and the magazine belonged Čeněk Adamec, Bohuš Pospíšil and Milan A. Tesař. The journal represented a Europe-wide unique. No other institution published a similar format of the journal, which conceived as the major topic of public opinion. It was a professional and popularization journal, which was addressed to experts and the general public. Individual subsections describe the specific content of the journal, which, inter alia, consist of professional articles of various kinds, reports on domestic and foreign researches, comments from readers and other sections. Special attention is given to information related to the field of media.

Abstract in English, Afrikaans and IsiXhosa. / This study investigates the first national poll tax levied on African men in the Union of South Africa. Known as the “general tax”, it was enacted in terms of the Natives Taxation and Development Act of 1925, and was imposed irrespective of a man’s income or impecuniousness. The historical background to the Act is outlined, and debates and disputes leading up to its promulgation are considered. The difficulties underlying the application, interpretation, and enforcement of the Act, are also examined. Court case judgments involving men who denied their inclusion under the Act’s central, racial definition of “native”, are explored. The case of one individual whose descendants were brought to Natal as “liberated slaves”, is discussed in some detail. The Act’s definition of “native” affected not only individual men, but also a number of black groups whose racial and tax status was in some doubt. Responses to a Native Affairs Department directive, explicitly excluding “Hottentots, Bushmen and Korannas” from the ambit of the Act, are accordingly investigated. Problems surrounding the Griquas, whose tax status was initially ignored in legislation and in official circulars, are investigated. The taxation of farm labourers, among the lowest paid workers in the country, is also examined. Queries and complaints from magistrates, white farmers and from African men are recorded. The interpretation of the Secretary of Native Affairs on the relevant provisions of the Act and his responses to queries and objections relating to the taxation of those workers, are also investigated. / Esi sifundo siphanda irhafu yokuqala yesizwe eyayibizwa kumadoda ama-Afrika kweMdibaniso woMzantsi Afrika. Le rhafu kwakusithiwa yi“rhafu jikelele”, kwaye yayisekwe ngokomthetho owaziwa ngokuba yiNatives Taxation and Development Act wonyaka we-1925, kwaye yayifunwa kuwo onke amadoda nokuba ahlupheke kangakanani na. Imbali yalo Mthetho inikiwe, kwaye kuphononongwe neengxoxo neengxabano ezakhokelela ekuphunyezweni kwawo. Kuqwalaselwe kwakhona ubunzima obavela xa kwakucelelwa ukuphunyezwa kwawo, indlela yokuwutolika nokuwunyanzelisa. Kukwaphononongwe nezigwebo zeenkundla zamatyala ezimalunga namadoda awayesala ukubandakanywa nenkcazelo yalo Mthetho, eyayicalula ngokwebala, neyayisithi “iinzalelwane”. Kuxoxwe banzi ngetyala losapho lwenye indoda olwaziswa eNatala kusithiwa “ngamakhoboka akhululweyo”. Kuphandiwe ngendlela ababeziva ngayo abantu xa kwaphuma isinyanzeliso seSebe Lemicimbi Yeenzalelwane, esithi “Amaqhakancu, AbaThwa namaKoranna” awafakwa wona kulo Mthetho. Inkcazelo yoMthetho ethi “iinzalelwane” yayingachaphazeli nje amadoda kuphela, yayichaphazela namanye amaqela abantu abantsundu ababengaqondakali ncam ukuba baloluphi na uhlanga, kwaye sisithini isimo sabo serhafu. Ziphononongiwe neengxaki ezazingqonge amaGriqua, wona ayenesimo serhafu esingahoywanga, engananzwanga nangokuseMthethweni nakwiimbalelwano zoburhulumente. Okunye okuphandiweyo kukubizwa irhafu kwabasebenzi basezifama, bona babengabona bahlawulwa kancinci. Zishicilelwe nezikhalazo nemibuzo evela kwiimantyi, amafama amhlophe namadoda ama-Afrika. Ziphononongiwe iindlela zokutolikwa kwezilungiselelo zoMthetho, zitolikwa nguNobhala wemicimbi Yeenzalelwane nendlela lo Nobhala awayephendula ngayo imibuzo nezikhalazo ezazibhekiselele kwabo basebenzi. / Hierdie studie ondersoek die eerste nasionale hoofbelasting wat op Afrika-mans in die Unie van Suid-Afrika gehef is. Hierdie sogenaamde “algemene belasting” is ingevolge die Naturelle Belasting en Ontwikkeling Wet van 1925 voorgeskryf, en is gehef ongeag ’n man se inkomste of onvermoëndheid. Die historiese agtergrond tot die Wet word uiteengesit, en debatte en dispute wat tot die uitvaardiging daarvan gelei het, word oorweeg. Die probleme verbonde aan die toepassing, uitleg en afdwinging van die Wet word ook ondersoek. Hofbeslissings rakende mans wat hul insluiting onder die Wet se sentrale, rasse-definisie van ‘“naturel” ontken het, word bestudeer. Die saak van een individu wie se afstammelinge as “bevryde slawe” na Natal gebring is, word in besonderhede bespreek. Die Wet se definisie van “naturel” het nie net individuele mans beïnvloed nie, maar ook ’n aantal swart groepe oor wie se rasse- en belastingstatus onsekerheid bestaan het. Reaksies op ’n aanwysing van die Departement Naturellesake, wat uitdruklik “Hottentotte, Boesmans en Korannas” van die toepassingsbestek van die Wet uitsluit, word dienooreenkomstig ondersoek. Probleme met betrekking tot die Griekwas, wie se belastingstatus aanvanklik in wetgewing en amptelike omsendbriewe geïgnoreer is, word verken. Die belastingbetaling deur plaasarbeiders, wat onder die laags besoldigde werkers in die land was, word ook bekyk. Navrae en klagtes van landdroste, wit boere en Afrika-mans word vermeld. Die uitleg van die tersaaklike bepalings van die Wet deur die Sekretaris van Naturellesake en sy reaksies op navrae oor en besware teen die belastingpligtigheid van daardie werkers word ook ondersoek. / College of Accounting Sciences / M.
