O intuito deste estudo foi o de realizar uma pesquisa qualiquantitativa, documental e exploratória sobre a produção científica nacional no tema \"pescado: alimento para consumo humano\" compreendendo o período entre 2002 e 2012. Os trabalhos foram classificados em duas grandes áreas: Saúde Pública, e Processamento do Pescado. Objetivou-se identificar a participação das regiões brasileiras; o pescado mais estudado; as entidades que mais pesquisam sobre o tema (públicas ou privadas); os aspectos em que a pesquisa sobre o tema contribui para o desenvolvimento do setor, e os principais avanços identificados nesse período de estudo. O estudo concluiu que houve um aumento do número de trabalhos produzidos no tema \"pescado: alimento para consumo humano\", entre 2002 a 2012; as pesquisas desenvolvidas vem contribuindo com um grande número de trabalhos voltados à Saúde Pública, sendo que estes apresentaram principalmente pesquisas de análises microbiológicas e físico-químicas; as instituições públicas foram as que mais apresentaram pesquisas dentro do período estudado; a região que mais realizou estudos foi a Sudeste; o pescado mais estudado foi origem marinha e a espécie de pescado mais encontrada nos estudos foi a tilápia (Oreochromis niloticus); o maior número de trabalhos foi apresentado no Congresso de Higienistas de Alimentos, seguido pelo SIMCOPE e base Capes, respectivamente. Os trabalhos, no geral, foram muito semelhantes e voltados à Saúde Pública, porém o SIMCOPE demonstrou maior número de trabalhos referentes ao Processamento do Pescado. A criação do Ministério da Pesca e Aquicultura gerou um aumento de investimento, por parte do governo no setor, incentivando a produção de peixes de cativeiro, como a tilápia. / The purpose of this study was to create a qualitative, quantitative, documentary and exploratory research on scientific productions with the theme \" fish : food for human consumption.\" published between 2002 and 2012 These studies were classified into two areas: Public Health, and Fish Processing. This study aimed to identify the participation of Brazilian regions; the most studied fish; entities with more research on the topic (public or private); aspects in which research on the subject contributes to the sector development, and major advances. The study concluded that the studies on this theme are increasing ; most of the of research were related to public health , and these studies had mainly microbiological and physico- chemical analysis; public institutions were the most productive researching on this theme within the study period; the region that most studies were conducted was the Southeast; the most studied fish and seafood species of fish was tilapia (Oreochromis niloticus); the largest number of papers were presented at the Congress of Food Hygienists, followed by Capes SIMCOPE and base, respectively. The work, in general, were very similar and focused on public health, but SIMCOPE demonstrated a greater number of jobs related to fish processing. The creation of the Ministry of Fisheries and Aquaculture has generated increased investment by the government in the sector, encouraging the production of captive fish, such as tilapia.

Para compreender as ações que conduziram os incidentes e como eles podem ser mitigados, pesquisadores devem identificar e medir os fatores que influenciam os atacantes e também as vítimas. A quantificação de segurança é, em particular, importante na construção de métricas relevantes para apoiar as decisões que devem ser tomadas para a proteção de sistemas e redes. O objetivo deste trabalho foi propor soluções para auxiliar o desenvolvimento de modelos de quantificação de segurança aplicados em ambientes reais. Três diferentes abordagens foram usadas para a investigação do problema: identificação de limitações nos métodos existentes na literatura, investigação de fatores que influenciam a segurança de uma organização e a criação e aplicação de um questionário para investigar o uso de métricas na prática. Os estudos foram conduzidos usando dados fornecidos pela University of Maryland e pelo Centro de Atendimento a Incidentes de Segurança (CAIS) vinculado a Rede Nacional de Pesquisa (RNP). Os resultados mostraram que as organizações podem se beneficiar de análises mais rigorosas e eficientes a partir do uso de métricas de segurança e que a continuidade das pesquisas nessa área está intimamente ligada ao desenvolvimento de estudos em sistemas reais / Abstract: With the increase in the number and diversity of attacks, a critical concern for organizations is to keep their network secure. To understand the actions that lead to successful attacks and also how they can be mitigated, researchers should identify and measure the factors that influence both attackers and victims. Quantifying security is particularly important to construct relevant metrics that support the decisions that need to be made to protect systems and networks. In this work, we aimed at proposing solutions to support the development of security quantification models applied in real environments. Three different approaches were used to investigate the problem: identifying issues on existing methods, evaluating metrics using empirical analysis and conducting a survey to investigate metrics in practice. Studies were conducted using data provided by the University of Maryland and also by the Security Incident Response Team (CAIS) from the National Education and Research Network (RNP). Our results showed that organizations could better manage security by employing security metrics and also that future directions in this field are related to the development of studies on real systems / Doutorado / Telecomunicações e Telemática / Doutor em Engenharia Elétrica

Undesirable leadership behaviours such as workplace bullying, destructive or toxic leadership are reportedly on the increase with negative effects on both the well-being of employees and the organisation (Salin, 2003). Since there is limited empirical evidence regarding the relationship between destructive leadership and psychological distress, the purpose of this study was to determine whether such a relationship exists among employees in South African organisations. Furthermore, the study intended to investigate whether gender has a moderating effect on this relationship. Destructive leadership behaviour is defined as the systematic and repeated behaviour by a leader, supervisor or manager that violates the legitimate interest of the organisation by undermining and/or sabotaging the organisation's goals, tasks, resources, and effectiveness and/or the motivation, well-being or job satisfaction of his/her subordinates (Einarsen, Aasland & Skogstad, 2007). With a sample (n = 200) of South African employees, the study adopted a correlational design and used the Destructive Leadership Behaviour Scale developed by Aasland, Skogstad and Einarsen (2008) as well as the Hopkins Symptoms Checklist-45 developed by Derogatis, Lipman, Richels, Uhlenhuth and Covi (1974) to assess the relationship between destructive leadership behaviour and psychological distress as well as the moderating effect of gender. The results indicated that two of the six hypotheses were accepted. H2, there is a relationship between overall destructive leadership and psychological distress, has been accepted. Furthermore H5, there is a significant correlation between the participants’ overall destructive leadership scores and overall psychological distress, was also accepted. Finally H6, gender has a moderating effect on the relationship between participants overall destructive leadership scores and overall psychological distress scores, was rejected. / Dissertation (MCom)--University of Pretoria, 2014. / gm2014 / Human Resource Management / unrestricted

This project is part of a larger study of the Serithi project in which semi-structured interviews were conducted with three hundred and seventeen HIV positive women from disadvantaged locations of Tshwane. In this study, the focus is on women’s experiences of an HIV positive diagnosis and the stigma associated with HIV and their level of disclosure. An analysis was made to whom they disclose, why they choose to disclose and the reaction of the people disclosed to, as well as reasons some people decided not to disclose. Theoretically, the Social Psychology approach was used to provide a theoretical framework as it attempts to understand the relationship between individuals, groups, and behaviour, invariably understanding the relationship between HIV related stigma experienced and the levels of disclosure of the women. As the aim of this study is to gain a deeper understanding of the experiences of HIV related stigma and disclosure encountered by South African HIV positive women, a combination of qualitative and quantitative measures was used. It was established from the research results that upon diagnosis, most women experience negative emotions and thoughts including shock, fear of death, sadness, anger, self-blame and denial. These reactions, however, over time seem to fluctuate and positive reactions such as acceptance of the HIV positive diagnosis and positive thinking come to the fore. Of the three hundred and seventeen respondents used in this study, only one hundred and ninety three women (61%) disclosed their HIV status to at least one person, being either partners (44%), family members (16%), parents (12%), friends (11%), in-laws (1,5%), and or people at work of which less than one percent of the women disclosed to, while 124 (39%) of the women did not disclose to anyone with the exception of the research assistants involved in this study. The issue of disclosure was analysed, and the most people disclosed to were partners, family members and parents. The women stated that it was easy for them to disclose to these people because they knew that they would not be judged and ridiculed. Instead, they felt assured that they would receive unconditional acceptance and support upon disclosure. Reasons for not disclosing included the fear of discrimination, rejection and blame, lack of trust and a supportive relationship. HIV related stigma was assessed through three different types of stigma, namely; 1) Experienced personal stigma (expectations of stigmatised individuals of how others will react to their condition), 2) Perceived community stigma (how the respondents think most people in the community feel and react towards HIV) and 3) Enacted stigma (the actual experiences of discriminatory acts due to their HIV positive status). From these assessments, it was established that respondents perceive community stigma to be the most prevalent and more negative than felt or personal stigma and enacted stigma, which was the least negative. Correlations between the various measures of stigma and disclosure showed that the women’s decision to disclose their HIV status is not only related to their stigma scores. Levels of personal stigma only played a role in disclosure to family members and friends and not in disclosure to partners. Perceived community stigma, which was high, did not have an impact on the level of disclosure. Therefore, the decision to disclose one’s HIV status is not totally influenced or dependent on HIV related stigma because other variables such as the quality of relationships also play a role. This raises the opportunity for further research as to what other aspects may have an impact on the issue of disclosure of one’s HIV positive status. / Dissertation (MA (Clinical Psychology))--University of Pretoria, 2007. / Psychology / unrestricted

The role and responsibility of the CEO of an organisation is an extensively researched field. This research project investigates the drivers of CEO turnover and the factors affecting the resultant post turnover corporate performance. An event study methodology, based on share price data from the JSE (Johannesburg Stock Exchange) was used to evaluate relative corporate performance. A pre event window of 250 trading days was used to establish corporate performance prior to the CEO turnover event, and a post event window of 500 trading days was used to evaluate the performance of the newly installed CEO. A sample of 143 CEO turnover events was examined, gathered during the period 1 April 2007 to 31 May 2012. 58% of the corporations undergoing CEO turnover were under performing their peers for one year prior to the turnover event, indicating that poor corporate performance was a major driver of CEO turnover. However, on further analysis, dissecting the data by corporation size yielded differing results, with 75% of small corporations undergoing CEO turnover in the ambit of under-performance, whereas in respect of large corporations, most CEO turnover was conducted in the circumstance of out-performance. Overall, CEO turnover yielded a statistically relevant improvement of 13.6% in post event corporate performance. However, if a corporation was significantly underperforming its peers prior to the turnover event, the new CEO was likely to improve corporate results by 96%, whereas, if a new CEO took over a significantly out-performing corporation, the post turnover corporate performance would reduce by 66%. A statistically relevant linear equation was formulated, predicting the level of post event corporate performance in relation to the pre event corporate performance. The variables of CEO tenure, CEO age, internal versus external CEO placements, and company size were also investigated, yielding interesting observations. / Dissertation (MBA)--University of Pretoria, 2014. / zkgibs2015 / Gordon Institute of Business Science (GIBS) / MBA / Unrestricted

Employees are important endorsers and gatekeepers to authentic conversations brands want to have with their consumers. This research focuses on predictors of employee endorsement. The purpose of the study was to investigate how internal marketing, internal engagement and perceived external prestige influence employees’ propensity to engage in positive word-of-mouth conversations about their company’s brands to their families, friends and close networks. Although the concept of word-ofmouth has received a lot of attention from researchers and practitioners alike, few studies have focused on the perspective of the initiator of word-of-mouth conversations, especially if the sender is employed by the brand being endorsed. From the literature reviewed an endorsement model was developed testing relationships between the constructs of (independent) internal marketing, internal engagement prestige and (moderating) perceived external prestige with (dependent) employee endorsement. A quantitative study was conducted through an email-based survey for which data from 156 employees from a South African bank was used to test hypotheses. A moderated regression was applied to establish the model fit to the data collected. The results of the model confirm that internal marketing and internal engagement are important predictors of employee endorsement. Although an organisation’s external prestige is theoretically important to employees, data reveals that the variable does not have a significant bearing on the relationships between internal marketing and internal engagement with employee endorsement. These findings are relevant for businesses seeking to leverage their employee potential not only in strengthening their branded services when servicing customers also growing their client base with an engaged customer base emanating from authentic trust relationships. / Dissertation(MBA)--University of Pretoria, 2014. / zkgibs2015 / Gordon Institute of Business Science (GIBS) / MBA / Unrestricted

Orientation: The level of CEO compensation and its relationship with organisational performance has generated considerable interest worldwide. In light of compromised mining productivity as a result of the recent labour unrest in South African, some commentators have questioned the justification of certain CEO compensation in the country’s mining industry. Research purpose: The primary purpose of this study was to describe the relationship between CEO compensation and organisation performance in the South African mining industry. Motivation for the study: A deeper understanding of the relationship would enhance knowledge when developing optimal CEO reward systems to ensure sustainability of the mining industry within the South African context. Research design, approach and method: The research was a quantitative, archival study involving 30 mining companies over a five year period. The statistical analysis techniques used in the study included analysis of normality variance and multivariate regression. Main findings/results: The main finding of the research was that there was a moderate to strong relationship between CEO compensation and organisational performance in the South African mining industry. However, operating expenses have progressively increased, putting performance under pressure. Furthermore, it was also found that company size plays an influential role in CEO compensation levels. Practical/managerial implications: While the CEO compensation appears to be generally aligned with the organisational performance, the findings suggest that boards of directors should focus on structuring reward systems more optimally to mitigate managerial rent seeking in large companies and unsustainability in smaller companies. Contribution/value-add: This study has contributed to the body of existing knowledge on executive pay for performance in the context of the South African mining industry. In addition, the study has demonstrated that the other non-performance related measures need to be considered in executive compensation design. / Dissertation (MBA)--University of Pretoria, 2014. / lmgibs2015 / Gordon Institute of Business Science (GIBS) / MBA / Unrestricted

Web 2.0 combines various electronic mediums, websites, blogs and applications across a wide range of devices and provides opportunity to communicate bespoke change messages to employees. The purpose of this study is to establish whether the use of Web 2.0 has an impact on employees’ resistance to change during the change communication process and whether employees show a preference for a communication medium in the context of organisational change. The failure of most change efforts are often ascribed to insufficient communication, but employee perspectives on the preferred communication medium and whether Web 2.0 communication impacts on employee’s resistance to change has been largely overlooked in academic literature. A descriptive research design approach was followed. Inferential statistics was used to apply parametric and non- parametric tests to analyse the data. A self-administered electronic survey was sent to 1337 employees across four sectors that have been affected by any type of organisational change between January 2012 and June 2014 in South Africa. The response rate was 19.8% (266 responses). The paper finds that there is a preference towards face-to face communication and that participation increases willingness to accept the change. There were no differences found in the manner in which females and males responded to the questions on willingness to accept the change. This research enables communication and change management professionals to assess the suitability of WEB 2.0 mediums during various stages of organisational change. The Blended Media Communication (BMC) Model to Reduce Resistance to Change is proposed based on the findings of the study. The research will add to the theory concerning an employee perspective on Web 2.0 change communication. / Dissertation (MBA)--University of Pretoria, 2014. / lmgibs2015 / Gordon Institute of Business Science (GIBS) / MBA / Unrestricted

The major theme of this research is the manner in which luxury good companies enter an emerging market economy, such as South Africa. The study thoroughly analyses how the emerging middle class of the country perceive luxury brands in term of being either status-giving or conspicuous. The study used a scale to measure luxury brands’ status and conspicuousness by analysing well-established international luxury brands that have a large footprint in South Africa as a reference point. The dimensions of luxury brand perception were measured when the scale between status and conspicuousness was utilised. This study employed a Factor Analysis as well as Perceptual Mapping in order to determine the relationship between conspicuous- and status consumption in the South African emerging market. The data was collected from 120 consumers who were owners of luxury products, but were deemed to be part of the upper middle class. Status and conspicuousness were revealed as two separate but related constructs, yet the South African emerging consumer does not discern between these two aspects. Strategic marketing implications for marketing managers were identified and discussed within the five brands that were selected, and their relevant product categories. / Dissertation (MBA)--University of Pretoria, 2014. / bmgibs2015 / Gordon Institute of Business Science (GIBS) / Unrestricted
