A growing problem of cyanobacteria in reservoirs around the world as a result of artificial eutrophication processes, generating a particular concern, because some species produce cyanotoxins, which can cause adverse effects on human health. The present work aims to characterize the spatial and temporal dynamics of phytoplankton, assessing their potential as ecological indicator of water quality in reservoirs semiarid region. The samples of water were collected monthly between 2009 and 2011, at three points along the dam Armando Ribeiro Gon?alves / RN. In each sample were measured physico - chemical analysis of water and biological components. We conducted a scientific dissemination activity, with distribution and reading primer on eutrophication, informative talk about water quality, questionnaires and performing a play in a public school in the city of Itaj? / RN. The reservoir was considered eutrophic in three points, taking into account the values of chlorophyll -a and phosphorus, adopted to characterize eutrophic environments of semi-arid areas. High density of cyanobacteria, with a maximum value of 2.227.862 c?l.ml- 1 and minimum of 43.456 c?l.ml- 1 was recorded in lentic and semil?ntico points throughout the study, exceeding the levels of drinking water (20.000 c?l.ml- 1) established in 2.914/2011 Ordinance of the Ministry of Health of Brazil. All samples contained microcystin, and 44 % had values superiores1μg L- 1. The thermal pattern of the water column showed micro stratifications with differences of less than 1 ? C from five feet deep. The distribution pattern was the type profile clinogrado with oxygen deficit in the bottom of the reservoir. Oxiclina from 10 meters depth was observed during the rainy season (May-June) in the two years of study. The phytoplankton community was represented by 10 functional groups: S1, M, H1, Lo, P, F, Sn, P, W2 and R. The assessment of the ecological status of the system by the index Q showed poor water quality. The results of the study show that the vertical variations were less pronounced than the seasonal variations of cyanobacteria and phytoplankton community in general in the reservoir. The presence of cyanotoxins confirms the need for the monitoring of water quality and measures to reduce eutrophication in water supply reservoirs semiarid RN and demonstrates the challenge for water managers and health authorities to ensure water quality and consequently minimize risks to human health. Compared to the lecture, the primer was considered more efficient in sensitizing the participants, featuring a dynamic practice, differentiated learning, create opportunities for students to rethink attitudes of respect and care for the environment, and shall have the opportunity to learn the subject content from your reality and living environment. The knowledge generated from the activity of scientific were seen as essential for raising awareness of some of the region`s environmental problems , such as eutrophication / O conhecimento da comunidade fitoplanct?nica, como parte integrante e din?mica dos processos de eutrofiza??o, fornece informa??es imprescind?veis para gest?o e manejo adequados. ? crescente o problema das cianobact?rias em reservat?rios em todo o mundo como conseq??ncia dos processos de eutrofiza??o artificial, gerando uma preocupa??o especial, pelo fato de algumas esp?cies produzirem cianotoxinas, que podem provocar efeitos adversos na sa?de humana. O presente trabalho objetiva caracterizar a din?mica espacial e temporal do fitopl?ncton, avaliando seu potencial como indicador ecol?gico da qualidade de ?gua de a?udes em regi?o semi?rida. As coletas da ?gua foram realizadas mensalmente entre 2009 e 2011, em tr?s pontos ao longo da Barragem Armando Ribeiro Gon?alves/ RN. Em cada amostragem foram medidas vari?veis f?sico-qu?micas da ?gua e analisados os componentes biol?gicos. Foi realizada uma atividade de divulga??o cient?fica, com distribui??o e leitura de cartilha sobre eutrofiza??o, palestra informativa sobre qualidade de ?gua, aplica??o de question?rios e realiza??o de pe?a teatral em uma escola p?blica do munic?pio de Itaj?/RN. O reservat?rio foi considerado eutr?fico nos tr?s pontos, levando-se em considera??o os valores de clorofila-a e f?sforo, adotados para caracterizar ambientes eutr?ficos de zonas semi-?ridas. Elevada densidade de cianobact?rias, com valor m?ximo de 2.227.862 c?l.ml-1 e m?nimo de 43.456 c?l.ml-1 foi registrada nos pontos l?ntico e semil?ntico durante todo o estudo, ultrapassando os n?veis de ?gua pot?vel (20.000 c?l.ml-1) estabelecidos na Portaria 2.914/2011 do Minist?rio da Sa?de do Brasil. Todas as amostras analisadas continham microcistina,e 44% delas apresentaram valores superiores1μg L-1. O padr?o t?rmico da coluna da ?gua apresentou microestratifica??es com diferen?as inferiores de 1?C a partir de cinco metros de profundidade. O padr?o de distribui??o foi do tipo perfil clinogrado com d?ficit de oxig?nio no fundo do reservat?rio. Oxiclina a partir dos 10 metros de profundidade foi observada no per?odo de chuva (maio a junho) nos dois anos de estudos. A comunidade fitoplanct?nica foi representada por 10 grupos funcionais: S1, M, H1, Lo, P, F, Sn, J, W2 e R. A avalia??o do estado ecol?gico do sistema pelo ?ndice Q demonstrou m? qualidade da ?gua. Os resultados do estudo mostram que as varia??es verticais foram menos pronunciadas do que as varia??es sazonais das popula??es de cianobact?rias e da comunidade fitoplanct?nica no geral no reservat?rio. A presen?a de cianotoxinas confirma a necessidade do monitoramento da qualidade da ?gua e tomada de medidas para minimizar a eutrofiza??o em reservat?rios de abastecimento de ?gua do semi?rido potiguar e demonstra o desafio para gestores de recursos h?dricos e autoridades de sa?de para garantir qualidade de ?gua e, consequentemente, minimizar riscos a sa?de humana. Em compara??o com a palestra, a cartilha foi considerada mais eficiente no sentido de sensibilizar os participantes, caracterizando uma pr?tica din?mica e diferenciada de aprendizagem, por oportunizar aos alunos repensarem as atitudes de respeito e cuidado com o meio ambiente, contando ainda com a oportunidade de aprender os conte?dos disciplinares a partir de sua realidade e viv?ncia ambiental. Os conhecimentos gerados a partir da atividade de divulga??o cient?fica foram entendidos como essenciais para a sensibiliza??o da popula??o para alguns dos problemas ambientais da regi?o, como a eutrofiza??o

Science dissemination has unquestioned role on intermediate science and society and it is a wide subject of research in education, considering that the construction of knowledge flows in different spaces, and, consequently, produces and disseminates representations. It presents as a motivator for reflection and as a necessary tool to prevent that knowledge do not become synonymous with domination and power. Thereby, the Astronomy assumes a remarkable role as a trigger of scientific dissemination process, due to its interdisciplinary character. From this viewpoint and the theoretical and methodological framework of the Theory of Social Representations (TRS), grounded by Serge Moscovici, this research, qualitative in nature, seek to answer: What are the social representations about scientific dissemination of Brazilian researchers that act in the field of astronomy? The work was based on Longhini, Gomide and Fernandes (2013) research, which delineate the Brazilian scientific community involved in Astronomy, identifying two groups of researchers with different training paths: one with postgraduate in education and related fields, and other with postgraduate in Physics or Astronomy. Thus, this study had the subquestion: Does the researchers of these groups have different conceptions about the practices of science dissemination? A sample was composed of six subjects, three of each formative course, who participated in semi-structured interviews analyzed following the steps outlined by Spink (2012). The results show that the science dissemination is part of the researches schedule s, with a positive image relative to promote scientific knowledge to population and similar on practical approach between the two groups. Point to two social representations of science dissemination: one for society in general, moved by passion, anchored in values and beliefs, in satisfaction of seeing the results that their actions bring to people's lives; and the other to their pairs. Regarding the first, the core of this work, emerge gaps that hinder the practice of science dissemination, such as lack of professionalism and difficulty of using language accessible to the lay public; the lack of appreciation, so far, of the area and the bureaucracy required in the execution of projects, which come from institutions and sponsoring agencies, and the negative representation about the media, in general, are added to the list of obstacles, inferring that science dissemination is a paradigm in construction. Other considerations are that astronomy is not part of basic education systematic way or the media in general and, not infrequently, in these areas, this science presents with misconceptions. And there is an intersection between science education and science dissemination, wherein the researcher must approach to the elementary school teachers and the population. There is an indication of expanding non-formal spaces of education and the creation of a specific policy for Astronomy. In short, the found representations ponder some of the concerns currently present in society and that are echoed in the theoretical framework of this study, demonstrating that, in Brazil, despite advances, in general, science dissemination, science education, and, specifically, Astronomy Education, are in a social fragility context. / A divulgação científica tem função inconteste na intermediação entre ciência e sociedade e é um campo fértil de investigação na educação, considerando que a construção do conhecimento flui em diferentes espaços, e, consequentemente, produz e dissemina representações. Apresenta-se como terreno motivador à reflexão e como ferramenta necessária para impedir que o conhecimento não seja sinônimo de dominação e poder. Nesse prisma, a Astronomia assume papel relevante como desencadeadora do processo de divulgação científica, devido ao seu caráter interdisciplinar. Sob esse olhar e à luz do referencial teórico-metodológico da Teoria das Representações Sociais (TRS), fundamentada por Serge Moscovici, esta pesquisa, de natureza qualitativa, buscou responder: Quais as representações sociais sobre divulgação científica de pesquisadores brasileiros que atuam no campo da Astronomia? O trabalho teve como base a pesquisa de Longhini, Gomide e Fernandes (2013), que mapearem a comunidade científica brasileira envolvida com a Astronomia, identificando dois grupos de pesquisadores com diferentes trajetórias formativas: um com pós-graduação em Educação e áreas afins e outro com pós-graduação em Física ou Astronomia. Assim, este estudo teve como subquestão: Os pesquisadores desses grupos têm concepções diferenciadas sobre as práticas da divulgação científica? Foi composta uma amostra de seis sujeitos, sendo três de cada trajetória formativa, que participaram de entrevistas semiestruturadas analisadas conforme os passos sugeridos por Spink (2012). Os resultados mostram que a divulgação científica faz parte da agenda dos pesquisadores, com uma representação positiva em relação a divulgar conhecimento científico à população e similar na abordagem prática entre os dois grupos. Apontam para duas representações sociais da divulgação científica: uma para sociedade em geral, movida pela paixão, ancorada em valores e crenças, na satisfação de ver os resultados que suas ações trazem à vida das pessoas; e outra para os seus pares. No que tange à primeira, âmago deste trabalho, emergem lacunas que obstaculizam a prática da divulgação científica, como a falta de profissionalização e a dificuldade de utilizar linguagem acessível ao público leigo; a falta, até então, de valorização da área e a burocracia exigida na execução de projetos, advinda das instituições e agências de fomento, e a representação negativa sobre a mídia, em geral, somam-se à lista dos obstáculos, inferindo-se que a divulgação científica é um paradigma em construção. Outras considerações são que a Astronomia não faz parte de forma sistemática do ensino básico e nem da mídia em geral e, não raro, nesses âmbitos, essa ciência apresenta-se com erros conceituais. E que existe uma intersecção entre a educação científica e a divulgação científica, sendo que o pesquisador deve se aproximar dos professores do ensino básico e da população. Há a indicação de se expandir espaços não formais de educação e da criação de uma política específica para a Astronomia. Em suma, as representações ora encontradas ponderam algumas das preocupações presentes atualmente na sociedade e que encontram eco no corpo teórico deste trabalho, demonstrando que, no Brasil, apesar dos avanços, de modo em geral, a divulgação científica, a educação em ciências e, especificamente, a Educação em Astronomia, encontram-se num contexto de fragilidade social. / Doutor em Educação

O desenvolvimento de um mÃtodo de avaliaÃÃo do nÃvel de implantaÃÃo do Planejamento e Controle da ProduÃÃo â PCP e sua disseminaÃÃo, a partir de uma visÃo do corpo funcional de uma empresa, foram o objetivo deste trabalho. Tal ponderaÃÃo busca identificar, atravÃs de um Ãngulo diferenciado, pontos fortes e pontos frÃgeis da gestÃo de empreendimentos de forma a focar as aÃÃes corretivas maximizando resultados. Para isso, foi desenvolvido e aplicado um questionÃrio de pesquisa, utilizando como base a listagem de 15 boas prÃticas, aprimoradas por RECK (2010) a partir de BERNARDES (2001). O questionÃrio supracitado possui 58 questÃes divididas entre avaliaÃÃo Ex-Ante, Planejamento e Controle da ProduÃÃo e avaliaÃÃo Ex-Post. Sua aplicaÃÃo foi realizada com profissionais das Ãreas de planejamento e controle, fiscalizaÃÃo e operaÃÃo das obras implantadas. Dada à importÃncia estratÃgica que obras de infraestrutura possuem tanto para o crescimento da economia, como para o bem estar da populaÃÃo, foi escolhida uma empresa deste ramo da engenharia para aplicaÃÃo da pesquisa, mas especificamente uma companhia de saneamento bÃsico. O mÃtodo de pesquisa aplicado foi o levantamento, utilizando como ferramenta a entrevista com tipologia de carÃter qualiquantitativo, em que os processos de planejamento foram analisados e criticados. Ao final deste, foram apontadas aÃÃes para adaptaÃÃo e melhoria dos procedimentos a partir da pesquisa qualitativa, indicando Ãreas passÃveis de aprofundamento do estudo. O estudo quantitativo apontou 4,6 como a mÃdia geral alcanÃada pela empresa estudada, o que caracteriza que a companhia possui um nÃvel mediano de prÃticas de PCP, jà o estudo qualitativo apontou o controle como ferramenta mais desenvolvida e o planejamento como sendo a menos evoluÃda. / The aim of the present work is the development of an evaluation method of the level of implantation of Planning and Controlling of Production â PCP and its dissemination, under the view of a functional body of a company. This statement aims at identifying, in a different perspective, strong and weak points of the management of enterprises focusing on the corrective actions maximizing the results. In order to do that, a survey was developed and applied, using for basis the list of 15 good practices, refined by Reck (2010) from Bernardes (2001). The survey mentioned above is made of 58 questions divided in evaluation Ex-Ante, Planning and Controlling of Production and evaluation Ex-Post. It was applied to professionals in the field of planning and controlling, inspection and operation of the works deployed. Due the strategic importance that infrastructure works have either to the growing of economy as to the well being of the population, an engineering company of the mentioned field was chosen to apply the survey, more specifically a basic sanitation company. The methodology used was the survey data, using as tool a quanti-qualitative interview, in which planning processes were analyzed and criticized. In the end, actions to adapt and improve the procedures were pointed from the results of the qualitative research, indicating new fields that are likely to be deeply studied. The quantitative study pointed 4,6 as the overall average reached by the company studied. It means that the company has an average level of practices of PCP. In the qualitative study, the research showed the control as the most developed tool and planning as the least evolved.

O empreendedorismo social surge como uma nova forma de empreender, preocupado acima da geração de valor econômico, com o potencial de acréscimo de valor social incutido em determinado setor da sociedade. As micro e pequenas empresas vêm sendo objeto de estudo da contabilidade ao longo do tempo, porém os negócios sociais não parecem estar recebendo atenção devida tendo em vista serem um tipo inovador de negócio, que se preocupa com a transformação de uma sociedade que cada vez mais se questiona sobre os impactos ambientais e de desigualdade social causados pelo sistema econômico vigente. Neste sentido, o presente estudo teve por objetivo analisar o estado atual de interação entre a contabilidade e empreendedores sociais e, para além disso, indagar de quais formas um uso mais qualitativo da contabilidade pode assegurar o êxito deste tipo de negócios. O trabalho coletou seus dados por meio de entrevistas semiestruturadas com empreendedores sociais e profissionais de contabilidade que prestam serviços a esses empreendedores. Como resultado da análise das entrevistas, pôde-se vislumbrar um cenário de distanciamento entre a contabilidade e os negócios sociais. Porém já existem profissionais atentos a essa nova vertente de negócio, profissionais contábeis que enxergam um papel de destaque desse tipo de empreendimento por seu caráter de transformação social. Pretende-se com a pesquisa, além de outras coisas, agregar visibilidade aos negócios sociais, despertar maior interesse pelo tema nas pesquisas em contabilidade e conscientizar os empreendedores sobre os benefícios que o uso de uma contabilidade de qualidade pode trazer para seus negócios / Social entrepreneurship emerges as a new way of undertaking, preoccupied not only with the generation of economic value, but also with the potential for added social value instilled in a sector of society. Micro and small enterprises have been an increasingly research subject in accounting over time, but social businesses do not seem to be receiving proper attention due to being an innovative type of business, one that concerns itself with the transformation of a society that increasingly ponders on the environmental impacts and social inequality caused by the current economic system. In this sense, the present study aimed to analyze the current state of interaction between accounting and social entrepreneurs and, in addition, to question in which ways can a more qualitative use of accounting ensure the success of this type of business. This work collected its data through semi-structured interviews with social entrepreneurs and accounting professionals who provide services to these entrepreneurs. Through the analysis of the interviews, we could notice a scenario in which there is still some distance between accounting and social businesses. However, there are already some professionals paying attention to this new kind of business, accounting professionals who see a prominent role in this type of enterprise for its character of social transformation. The aim of the research is to add visibility to social affairs, to raise awareness of the topic in accounting research, and to make entrepreneurs aware of the benefits that the use of quality accounting can bring to their business

Nutrigenômica representa disciplina cientifica recente que surgiu na era do pós-genoma humano, sendo seu foco de estudo a interação gene - nutriente. Profissionais com educação universitária que atuam na área da alimentação e nutrição e da saúde relatam ter dificuldades no entendimento dos princípios dessa disciplina. Recursos digitais como animações representam ferramentas interessantes para o processo de ensino-aprendizagem da nutrigenômica. Dessa forma o objetivo do presente trabalho foi o de desenvolver material educativo digital intitulado \"Fundamentos da Nutrigenômica\", baseado nas animações \"Modulação da expressão gênica por nutrientes e compostos bioativos dos alimentos\" e \"Nutrigenômica e redução do risco de câncer\", para divulgação científica da nutrigenômica para profissionais da área da alimentação e nutrição e da saúde. Para desenvolver o material educativo digital, utilizou-se esquema que se divide nas seguintes etapas: análise e planejamento; modelagem; implementação; avaliação e manutenção.

Mais de 80% dos participantes concordaram fortemente ou concordaram com as seguintes afirmações: \"O material educativo digital é de fácil manuseio\"; \"A utilização desse tipo de recurso tem vantagens sobre textos\"; \"O material educativo digital trouxe conhecimentos novos sobre Nutrigenômica\"; \"Os conceitos estão expostos de forma clara\"; \"Meus conhecimentos anteriores foram suficientes para aprender com o material educativo digital\"; \"Os textos estão redigidos com clareza\"; \"As animações auxiliam a compreender os fenômenos exibidos\"; \"Aprendi bastante sobre os fundamentos da nutrigenômica com o material educativo digital\". Conclui-se que o material educativo digital \"Fundamentos da nutrigenômica\" representa ferramenta útil para divulgação científica da nutrigenômica junto a profissionais da área da alimentação e nutrição e da saúde. / Nutrigenomics represents recent scientific discipline that has emerged in the post-human genome era, with focus on gene - nutrient interaction. Professionals with university education working in the field of food and nutrition and health report having difficulties in understanding the principles of this discipline. Digital resources such as animations represent interesting tools for the teaching and learning of nutrigenomics. Thus the objective of this study was to develop digital learning material entitled \"Fundamentals of Nutrigenomics\", based on the animations \"Modulation of gene expression by nutrients and bioactive food compounds\" and \"Nutrigenomics and risk reduction of cancer,\" for scientific dissemination of nutrigenomics for professionals in the food and nutrition and health areas. To develop the digital learning material, we used the scheme that is comprised by the following steps: analysis and planning, modeling, implementation, evaluation and maintenance. The animations were produced with the PowerPoint 2007 and EM Video Converter softwares. We evaluated the digital educational materials through a questionnaire provided to 20 professionals (nutritionists, pharmacists, food engineers, biologists, chemist, dentist and zootechnist) registered or not in Graduate Programs from University of Sao Paulo in the areas of food and nutrition and health. Over 80% of participants strongly agreed or agreed with the following statements: \"The digital educational material is easy to handle\", \"The use of this resource type presents advantages over text\", \"The digital learning material brought new knowledge on Nutrigenomics\" , \"The concepts are clearly exposed\", \"My previous knowledge was sufficient to learn from the digital learning material\", \"The texts are written with clarity\", \"The animations help to understand the exhibited phenomena\", \"I learned a lot about nutrigenomics fundamentals with the digital learning materials\". We conclude that the digital learning material \"Fundamentals of Nutrigenomics\" represents a useful tool for scientific dissemination of nutrigenomics for professionals in the field of food and nutrition and health.

The intrinsic characteristics of the Framework for Strategic Sustainable Development (FSSD) make it useful in moving society towards sustainability. However, most of the change agents who work with the FSSD report that it is not diffused widely enough to have a systemic impact on society. The purpose of the study is to enable those who wish to foster such diffusion to be more effective in their efforts by giving them information they need to strategically plan those efforts. An ‘important factors for diffusion’ lens is constructed from Diffusion of Innovations theory and social marketing concepts, and verified with case studies of the diffusion of Biomimicry 3.8, GRI and Cradle to Cradle. 152 current barriers and enablers to broader diffusion of the FSSD are identified from interviews with 27 practitioners and a survey of 58 additional practitioners. These are scored against the lens to determine the current diffusibility of the FSSD, then distilled and influence flows between them mapped, to identify seven leverage points for broader diffusion. Interrelations between these leverage points, as well as other emergent themes, are discussed, conclusions are drawn, and further research suggested. / <p>irena.efrem@gmail.com; sijme@sijme.com; scott@notutopia.com</p>

Résumé confidentiel / Résumé confidentiel

A university’s alumnus grouping is one of its most valuable assets in terms of its potential financial, strategic and social contribution towards the credibility and longevity of the institution. The goodwill and support of a primary stakeholder grouping such as the alumni is crucial to the aspirations of a Higher Education institution wanting to prosper in a fast-changing and highly competitive market. Alumni members have the capacity to assist in strategically positioning a tertiary institution as a market leader in the South African Higher Education Sector (SAHES) by means of representation on the institutional council and their involvement in networking, lifelong learning, career services, mentoring, fundraising and community development activities. In light of the restructuring and transformation that this sector has undergone since 1994, building and maintaining valuable relationships with alumni stakeholders of tertiary institutions in South Africa has become a new and more difficult challenge. The integrated network approach of relationship management could give an institution the opportunity to create a win-win situation for all stakeholders involved. Information technology has had a significant impact on the power structure and relationship between organisations and their publics, stakeholders and the media. It has become extremely difficult for organisations to define and segment these audiences as, for example, Internet audiences are widely spread across geographical, cultural, and economic boundaries. This makes the packaging and dissemination of information a much more challenging task, as information needs to be generic enough to be commonly understood, but should also be personalised in such a way that it still addresses the different audience segmentations effectively. However, the identification and profiling of target audiences is critical for successful information dissemination, as this knowledge will guide the information managers within organisations in compiling relevant (to the target audiences) content and packaging the information in a way that is most suitable to the needs and resources of the targeted group. At the core of developing an alumni network is a secure database with an interactive Web-based platform allowing the alumni management teams and members to disseminate and share relevant information freely. According to a research project (the first phase of a longitudinal study) about disseminating information to UJ alumni, 98,2% of the respondents indicated that they wanted to have contact with the UJ Alumni Relations Office (Barnard, Rensleigh & Niemann, 2005). The majority of respondents, 86,7%, indicated that they preferred to receive the information via electronic mail or from the website. The research findings indicated that the UJ alumni stakeholder group is part of a privileged section of the South African population in the global and national digital divide. Thus, the alumni management of UJ had the opportunity to explore and use the information-sharing options offered by online and digital technologies. This research project forms the second phase of the ongoing research project in an attempt to discard the “one-size-fits-all” notion with regard to information sharing with the alumni stakeholders of tertiary institutions in South Africa. The aim of this research project is to determine the extent to which an online community portal could manage the information needs of alumni stakeholders in the SAHES, using the alumni of the University of Johannesburg as a case study. Establishing an online (virtual) community Web portal for UJ alumni will support a customised approach in terms of information content, dissemination, context and commerce. An online community environment will offer alumni opportunities to re-establish contact with peers and nurture relationships with one another through frequent social interaction (chat). Such a facility would allow and encourage conversations that are of value to all stakeholders, as these communities can exist beyond the boundaries of location and time. They foster not only the potential to promote business-to-business (B2B) and business-to-consumer (B2C), but also consumer-to-consumer (C2C) interaction and could even exploit the possibilities of human-resource placements. The research consisted of an extensive literature review followed by a quantitative empirical survey and a qualitative discussion forum. The purpose of the literature review was to establish a theoretical framework in order to lay a solid foundation from which the empirical research was conducted. The different components of the research problem were discussed as well as possible variables that could influence the research problem. The restructuring of the South African Higher Education Sector was investigated, with specific focus on the University of Johannesburg and its alumni stakeholder group, taking an in-depth look into the value that an alumni stakeholder group holds for an institution. The management of alumni information needs was discussed, using Web-technology as focal point. Online community portals were defined, emphasising the benefits that this information tool could have for Higher Education alumni. As part of the quantitative study, an empirical survey was conducted in April 2006 among the alumni of the University of Johannesburg to determine their information needs concerning an online community portal, and the content required of such an online community model. A total number of 10 380 questionnaires was distributed to graduates of the University of Johannesburg at the Autumn Graduation ceremonies. The questionnaire consisted of four sections, namely Section A: Biographical Information, Section B: Online Activities, Section C: Alumni Information Services and Section D: Alumni Community Needs. In total, 1 703 questionnaires were completed and returned by these graduates to the UJ Alumni Relations Office. In addition, a qualitative discussion forum was conducted among 35 alumni management representatives from fourteen SAHES institutions during August 2006. The representatives indicated how information was disseminated electronically to alumni target audiences and their opinions towards alumni online community portals were tested. The research results indicated that an online community portal, could manage, to a great extent, the information needs of alumni in the South African Higher Education Sector (UJ alumni case study). Consequently, a prototype was proposed for an online community portal for SAHES alumni that would have a significant impact on the information and communication methods used to build alumni networks, for the benefit of both the alumni stakeholders and the Higher Education institutions in South Africa. Although the alumni of the University of Johannesburg served as a case study for this research project, the proposed prototype could be tailored to the needs of other alumni organisations throughout the South African Higher Education Sector. In terms of inter-institutional collaboration, this research project offers an opportunity to liaise and share information with other alumni organisations of the SAHES. This could result in successfully identifying a best practice model for managing the information needs of alumni stakeholder groups of tertiary institutions in developing countries, which is significantly different from the philanthropic approach to these stakeholder groups in first world countries. As a result, the employment sector of Higher Education institutions in South Africa could gain from the research outcomes, as the proposed prototype will offer an ICT and Web-based solution which could be applied for the mutual benefit of the relevant stakeholder groups and the institutions. / Prof. Chris Rensleigh

The Finnish police have power and influence as they are gate keepers of the criminal justice system. Governmental crime reduction policies rely on the actions of the police and in 2020 the Finnish police made a TikTok video to warn adolescences about dangers of sexting. My thesis uses Lerner’s Just world hypothesis and Bacchi’s What’s the problem represented to be as a theoretical framework, and multimodal critical discourse analysis (MCDA) to identify how the victim is represented in the TikTok video. The analysis on the content of the TikTok video is representing the victim as culpable for the crime against him/her. When the analysis is applied to the theoretical framework, it can be argued that the instructive TikTok video bears pressing social and institutional problems and extends people’s responsibility for avoiding crime and therefore fails achieving a balanced policy between crime prevention and criminal justice response.
