- Description: The researcher wish to shed light on the health of the victims’ family members, who had in common, the traumatic experience of having one or more of their family members brutally murdered by a serial killers, and that they numbered fourteen people, who were residents in Wards 23 and 24. Nine of the fourteen victims were females and five were males, young and old. Some victims worked at Mzamba Wild Coast Cassino Hotel, one of those workers originally came from Kwa Zulu Natal at Umzimkhulu local municipality. Serial killers either attacked the victims in their homes, whilst they were fast asleep, many of the atrocities were witnessed by their children, or they were attacked in an open field when they were dropped-off from their place of work at midnight. The serial killers, used tools like hammers, to knock victims on the heads, thereby rendering them unconscious; bush knives were then used for the removal of certain body parts. Most victims were residents of Ward 24 which is nearer Mzamba Wild Coast Cassino Hotel. Many of the victims’ bodies showed evidence of head injuries, mutilation of body parts or ‘genital mutilation’, it is alleged that private parts were used for muti purposes. There was evidence that females had been raped. Post trauma was an experience that left many in the villages of Mbizana marked by fear and anxiety. When a serial murder occurred it demanded the attention of all South Africans for several reasons, especially because it dramatically threatens and profoundly challenges our sense of safety, in particular our sense of personal safety. The serial killing as a phenomenon, challenges the larger society throughout the country, it is an emotive subject. The study is concern with prolonged soul suffering without healing, a pastoral counselling services was rendered to victims’ family members with recommendation of reconciliation and forgiveness as therapeutic measures. The study concludes by calling upon the Church as congregation to include to her programmes the topic of serial killing. The study makes recommendations to the Church to empower, make awareness, teach, and offer counselling to the congregation, that denominations must approach theological institutions for an introduction of modules that cover the concept of serial killing.

- Description: Nurses are confronted with numerous work-related stressors that can result in burnout. This can contribute to absenteeism and high turn-over rates in the nursing profession. A review of the literature indicated that psycho-educational interventions to increase resilience could be an effective way of addressing this problem. The study aimed to develop a positive clinical-psychology approach to increasing resilience in State employed nurses. The study used a mixed-method approach to determine the current psychological functioning of a sample of 87 nurses. Quantitative data on personality traits, character strengths and levels of resilience were obtained, using the NEO PI-R, VIA – IS, and Resilience Scale. Qualitative data on the coping responses of nurses were obtained through the thematic analysis of focus groups. These data were integrated to create a positive clinical psychology conceptualisation of resilience and to develop therapeutic guidelines for a group psycho-educational intervention. The results of the study indicated a struggling psychological profile. This was defined as the ability to deal with work-related stressors – but with the potential risk of developing symptoms of burnout. The moderate levels of resilience were attributed to elevated character strengths in the sample. The distribution of personality traits indicated that the nurses in the sample were at risk of developing burnout; and this prevented them from flourishing. These data were synthesised to create therapeutic guidelines for developing resilience aimed: (1) increasing emotional stability and invulnerability; (2) increasing agreeableness; and (3) increasing conscientiousness. These guidelines were based on the personality traits that were deemed to negatively impact the resilience of the nurses. These personality traits were correlated with several character strengths that displayed strong relationships with resilience. This indicated that resilience could be developed through the cultivation of the following character strengths: perspective; perseverance; fairness; forgiveness; leadership; love; zest; hope; curiosity; and appreciation of beauty and excellence. These character strengths were identified to facilitate the positive adaptation of the personality traits identified in the therapeutic guidelines. A group psycho-educational intervention was developed, using the positive clinical psychology conceptualisation of resilience. The literature was reviewed to identify techniques to cultivate the ten character strengths specified in the therapeutic guidelines. These techniques were adapted to create experiential learning processes for the intervention. This psycho-educational programme can be applied as a secondary and tertiary intervention. It can be used to increase resilience to prevent burnout among nurses. It can also be used to psychologically empower nurses that have existing symptoms of burnout.

- Description: Food security is of major importance due to the increasing world population with 8.9 billion people expected by 2050 (Cohen, 2003). Diuraphis noxia (RWA), have caused aggravating, massive losses to wheat farmers in many areas of the world. If unchecked, RWA are able to destroy plants resulting in major economic impacts (Botha, 2013). Due to ineffective use of other control methods, the Small Grains Institute in Bethlehem, South Africa, have therefore developed resistant cultivars to the known RWA subtypes over the past decades through intensive breeding programmes (Tolmay et al., 2006). Climate change has however become a major factor threatening food security especially with the observed increase in CO2 from less than 300 ppm in pre-industrial period to the current 385 ppm and is predicted to reach 550 ppm by 2050 (IPCC, 2007; Meehl et al., 2007). Elevated CO2 concentration may affect individual species of a community hence the need to understand the wheat-aphid interactions. In this study, population growth rates and virulence of RWA SA1 at ambient (385 ppm) and elevated (450 ppm) CO2 concentration were evaluated on two wheat cultivars: Tugela Dn (resistant) and Scheepers (susceptible). Fluorescence microscopy techniques using aniline blue were used to investigate feeding related damage caused by RWA SA1 through an examination of callose deposition at the two CO2 concentration. A two-dimensional gel electrophoresis method was developed in order to determine the effect of RWA SA1 on the wheat cultivars proteome at the two CO2 concentration. Differentially expressed proteins that were up or down regulated more than two fold were identified using PDQuestTM Basic 2D Gel analysis software. Populations of RWA SA1 increased significantly on the two wheat cultivars at both CO2 concentration. Although the population growth rate for RWA SA1 on both cultivars was generally exponential at all treatments, growth at elevated CO2 concentration was noticeably faster with populations increasing 3 fold in 14 days as compared to the 2 times at ambient CO2 concentration. Hence, both cultivars provided a better quality host for RWA SA1 at 450 ppm than 385 ppm. There was no significant difference between RWA SA1 population on Tugela Dn and on Scheepers at elevated CO2 concentration on day 14 after infestation which means there was a change in the resistance mechanism in Tugela Dn at this condition. Approximately 70% of the total leaf showed chlorosis by 21 days of aphid infestation for both cultivars although the susceptible cultivar was more vulnerable. There was low callose deposition in the controls (uninfested plants) but heavy callose in infested plants due to aphid feeding. A proteomics approach was used as a pilot study to investigate whether it would be possible to identify the changes in the resistance mechanism during aphid infestation under elevated CO2 levels. The major changes in the proteome of the control group (uninfested Tugela Dn at ambient versus elevated CO2 concentration) occurred in the early events (day 1-7) in the molecular weight range of approximately 25 kDa to 55 kDa are mainly within the basic to neutral pH range. This was suggested to be a result of mechanisms to adjust to the CO2 concentration. Elevated CO2 results in instant higher photosynthetic rates and C:N ratios as well as changes in expression levels of SA-dependant defense genes (Lindroth 1995; Hughes and Bazzaz, 2001; Sun et al., 2013). Because most of these changes are directly regulated by proteins, it is expected that the most differential protein expression will occur immediately after the atmospheric changes (early events) as was shown in the study. Infested plants under elevated and ambient conditions showed that the stress conditions gave rise to differentially regulated proteins within the wheat proteome. Most changes occurred elevated CO2 levels. It can be suggested that the changes were a result of differentially regulated plant defence proteins which fall in this range (25 kDa - 80 kDa) such as peroxidases, chitinases and β-1.3-glucanases as well as protein kinases, heat-shock proteins and photosynthetic proteins. These results indicate that there has been changes in the resistance due to elevated CO2 because of the evident changes in the proteome. If so, then the results will be similar to those documented by Louw (2007) where up-regulation was due to putative storage proteins, proteins involved in photosynthesis, heat shock proteins and defense proteins. Of course, the pI value and molecular mass of the proteins and the identification of the proteins in these spots, must be determined in future work to specifically identify whether these suggestions are authentic. However, Louw (2007) also reports that the susceptible Betta wheat cultivar, displayed a defence response similar to the HR although it was unable to up-regulate specific defensive proteins against RWA infestation but proteins for broad resistance. Although the changes in the proteins in infested Tugela Dn under elevated CO2 concentration were not accurately identified, the defense mechanism is similar to that portrayed by the susceptible Betta wheat cultivar which shows that the resistance mechanism had been overcome. Because this was a pilot study and preliminary results were obtained due to limited funding and time constraints, suggestions were made on how to further develop the method to obtain statistically significant results.

- Description: In view of the important role that small businesses play in the economic development of most economies in the world, including South Africa (Adeniran & Johnston, 2012:4088; Kongolo, 2010:2290), as well as the survival challenges that they face, the purpose of this study was to propose a framework for effective mentoring. This framework can be used to develop the business management skills of black small business owner–managers which will eventually increase the survival of small businesses in South Africa. As such, the primary objective of this study was to gain an understanding of the conditions required for effective mentoring of black-owned small businesses by empirically identifying the factors that influence effective mentoring of these businesses. If mentoring programmes for black-owned small businesses can be effective, the high failure rate of these businesses could be reduced, which may influence the South African economy positively. This study sought to review previous findings and theories on mentoring and small business development, and then contextualise these to black-owned small businesses. A comprehensive literature review revealed potential factors which could influence the effectiveness of mentoring of black-owned small businesses. Four categories of these factors were identified, namely relational-based, non-relational based, cultural and demographical factors. These factors guided the collection of primary data in this study.

- Description: Utilising the Grounded Theory Research Method, this study identified a range of open, axial and selective codes, through a literature review, which resulted in the formulation of a proposed theory of how war economies are formed and maintained. Based on the theoretical proposition of the proposed theory, a policy framework for dismantling such war economies was also developed and presented. The proposed theory of war economies essentially argues that war economies are formed in post-colonial sub-Saharan Africa because of the existence of an artificial state. The existence of an artificial state is ascribed to the emerging legacies of colonial state formation processes, which created failed state entities which are unable to produce public goods for all its citizens because of its inability to maintain a monopoly of violence whilst maintain full administrative control over its territory. This inability results in an increase in the vulnerability of state and non-state actors. In response to these vulnerabilities, both state and non-state actors established a range of parallel political, economic and military structures. These structures in turn made use of both network and resource capacities to create an environment where politics are economised and conflict is commercialised, in order to mitigate the impacts of state failure and the inability to produce public goods. The result of the creation of an environment where politics are economised and conflict is commercialised, is the creation of incentives, structures and processes to ensure that conflict and associated conditions of instability are sustained in order to ensure primitive accumulation of wealth and resources. Based on the core theoretical proposition of the proposed theory, the study also presents a broad policy framework for dismantling war economies. In broad terms the framework proposes an integrated state-building process, based on a range of policy mechanisms aimed at maintaining a monopoly over violence, increasing administrative control, dismantling conflict networks and ensuring effective and efficient resource management.

- Description: Publisher version , The extent of microplastic pollution (< 5 mm) in the southern hemisphere, particularly southern Africa, is largely unknown. This study aimed to evaluate microplastic pollution along the south-eastern coastline of South Africa, looking at whether bays are characterised by higher microplastic densities than open stretches of coastline in both beach sediment and surf-zone water. Microplastic (mean ± standard error) densities in the beach sediment ranged between 688.9 ± 348.2 and 3308 ± 1449 particles·m− 2, while those in the water column varied between 257.9 ± 53.36 and 1215 ± 276.7 particles·m− 3. With few exceptions there were no significant spatial patterns in either the sediment or water column microplastic densities; with little differences in density between bays and the open coast (P > 0.05). These data indicate that the presence of microplastics were not associated with proximity to land-based sources or population density, but rather is governed by water circulation.

If South African macro and social policy explicitly aims to be ‘inclusive’, it is important to know how the average [median] South African income level changed over the first fifteen years of democracy. Common summary measures of economic progress such as GDP per capita may mask the standard of living experienced by the majority of the population in any particular period. Tracking the progress in the middle strata of South Africa’s income distribution provides a fresh perspective on the nature of economic progress in the country. This is against a worrying backdrop of rising income inequality post-1994 (Van der Berg and Louw, 2004; Hoogeveen and Özler, 2006; Leibbrandt et al, 2010). The paper is structured as follows. Section 2 motivates for the importance of focussing on the actual middle of the income distribution and highlights the emphasis on reducing income inequality within South African macroeconomic and social policy. Issues of comparability in the data and the choice of definition for the middle are discussed in section 3. Section 4 presents descriptive statistics relating to changes in incomes, and ends with a brief analysis of non-income measures of progress. The final section summarises the main findings and concludes.

- Description: To begin a review of the purpose(s) of ESD research, we must first ask the basic question of the purpose of research generally. Definitions of research normally centre on it comprising sys-tematic investigation which contributes to knowledge or under-standing of phenomena or a problem. A distinction is common-ly drawn between pure or basic research which focuses on understanding phenomena and issues, and applied research where the primary emphasis is on research which contributes to the solution of problems or some systemic improvement ra-ther than knowledge for its own sake. Some commentators see action research as a third category as it is predicated on the researcher being part of the research process which itself is committed to personal or social change. ESD research as an area of interest is perhaps unusual because it accommodates and crosses these categories. It also engages in philosophic research regarding cultural, worldview and ethical dimensions of sustainability education – critically important dimensions of ESD research, but not within the scope of this chapter. Re-search on – say – the relative effect of different pedagogies, or how a learning environ-ment affects learning, may be thought of as basic research, but at another level, ESD research is often purposeful beyond the accumulation of understanding about educational processes.

- Description: The purpose of this thesis is the construction of a test bench for the assessment of the NVH behaviour of a newly manufactured VW Polo 5. This will be done in collaboration with Volkswagen South Africa. Firstly, in order to gain a better understanding of the requirements such a test bench has to fulfill, the VW Polo, the guidelines prescribed by VW as well as the actual testing procedure implemented by VW Uitenhage will be analysed. Thereafter, the main section of the thesis will deal with the construction of the test bench. As agreed upon with Volkswagen Uitenhage, a test bench will be built during the course of the studies. This test bench will allow stimulation in low frequency as well as high frequency ranges and in addition to that, a second version of the test bench with optimised costing will be derived from the first one. The second model will only allow stimulation in high frequency ranges. During the thesis, a version of the test bench, the RTB-HC, has been developed which enables the stimulation of the high and low frequencies. In addition, a cost optimized version was developed. This version will be referred as RTB-LC. This version allows only a high frequency excitation.

- Description: The creation and proliferation of PHP-based Remote Access Trojans (or web shells) used in both the compromise and post exploitation of web platforms has fuelled research into automated methods of dissecting and analysing these shells. Current malware tools disguise themselves by making use of obfuscation techniques designed to frustrate any efforts to dissect or reverse engineer the code. Advanced code engineering can even cause malware to behave differently if it detects that it is not running on the system for which it was originally targeted. To combat these defensive techniques, this paper presents a sandbox-based environment that aims to accurately mimic a vulnerable host and is capable of semi-automatic semantic dissection and syntactic deobfuscation of PHP code.

- Description: The male-dominated nature of the construction and engineering industries is a well-known phenomenon. This research provides insight into the skills required by female managers in order to manage successfully in these industries dominated by males. The primary purpose of this research is to identify the skills profile of female managers in the construction and engineering industry of Nelson Mandela Bay (NMB). Even though the number of female managers in senior management positions is increasing, South Africa still has a long way to go before men and women are considered equal with regard to the roles that they play and the positions that they occupy in the work-place (Mail & Guardian Online, 2012: 1). Therefore, the aim of this study is to identify the skills needed by female managers in the construction and engineering industry of NMB. This study attempts to provide answers to the following research questions: What are the management skills a manager should have? What is the skills profile of female managers in the construction and engineering sector of NMB? Is there a skills gap in the current literature? The literature overview was conducted on roles, functions and skills of managers as well as female managers in male-dominated industries from journals and books published between 2000 and 2014. Topics researched included the roles and functions of managers, generic management skills and industry-specific management skills, females as managers and leaders, barriers to managerial success for females, and the nature of the construction and engineering industries. Chapter four discusses the research design and methodology used in this study. The quantitative research approach was used in order to solve the main problem of this study. A non-probability sampling method was used for this study. Purposive sampling and snowball sampling methods were used. These methods seemed most appropriate given the small sample size, the fact that self-completion questionnaires were used to gather data from female managers, and the fact that the researcher investigated only the skills exhibited data. The Master Builders’ Association was contacted in order to identify respondents in construction. Respondents in engineering were identified using snowball sampling, which forms part of non-probability sampling. A questionnaire was developed based on the management skills identified in the literature study conducted. Primary data was collected through e-mail distribution of a cover letter requesting the respondent to complete the attached questionnaire. The data was then loaded on an Excel data base for further use and analysis. Once primary data had been collected, it was analysed using appropriate statistical methods. Descriptive statistics were used to analyse the data to determine the skills’ profile of female managers in the construction and engineering industry of NMB, as reflected in the collected data. These results were then used to identify areas for further research. The analysis revealed that the majority of the sample was between the ages of 29 and 38 years old and employed in the construction industry. The sample mainly consisted of top level managers with a Masters as their highest educational qualification (41 per cent). The majority of the respondents agreed that conceptual, technical, political, analytic, administrative, and diagnostic skills are required to effectively manage an organisation. Based on the findings, the majority of the respondents strongly agreed that leadership, planning, organising, conflict management, and project management skills are industry-specific management skills required to manage effectively in the construction and engineering industry. The majority of respondents indicated that they had learned these skills through workplace training and experience. The majority of the respondents agree that female managers excel in certain managerial skills and even believe that female managers possess different skills to those of male managers. The results of this study are expected to create awareness of the current state of the construction and engineering industry in NMB. The information will enable employers as well as FET institutions to create interventions and equip females with the necessary skills to become engineering and construction professionals.

A sociological analysis of biodiversity management in Nigeria

- Description: The central thesis of this study addresses biodiversity challenges from a social relations perspective. This is viewed from the standpoint of enhancing sustainable bioresource-use systems from a behaviour change departure. The study reviewed the activities of organisations in Nigeria which focus on bioresource management. The review focused on how the organisations view, conceive and implement activities which aim to address biodiversity loss emphasising how these aspects inform the concept of programme design, planning and implementation. The strategies were weighed against theories and techniques in behaviour change. The study argues that it should be recognised that the challenges of biodiversity loss have a strong relationship with how a society is socially constructed, and that addressing the challenges will require a systematic approach aimed at social construction, using efficient techniques to ensure behaviour change. The objective of the study was to acquire insight on how programmes which aim at addressing biodiversity loss in Nigeria approached behaviour change towards sustainable bioresource-use practise. The study captured these insights in a set of themes which provided an improved analysis on the dynamics of behaviour change and biodiversity management in Nigeria as well as extrapolated these findings to articulate new ideas on how to address the challenges of biodiversity loss in Nigeria. Through analysing basic suppositions and exposing contradictions, social science disciplines examine the credibility of arguments and key concepts that commonly remain unquestioned. Based on this premise, critical assumptions on biodiversity management were challenged by the study. Furthermore, the study articulated questions which have been raised in recent years from a variety of social science perspectives on biodiversity management concerns. The study postulated the need for biodiversity management to be approached from a social-construct perspective in rethinking the discourse on unsustainable bioresource-use patterns. The thesis derives from an eco-sociology framework rooted in human interaction analysis, which is connected with approaches in the social science of functionalism and behaviourism. The concepts and ideas discussed in the thesis lay out the main dimensions relevant to the discourse on behaviour change-biodiversity management. The study’s conceptual and theoretical underpinning discussed biodiversity management concerns from a global context and narrowed the discussion down to country specific contexts. Within these contexts, the study discussed issues of policies, legal systems, political and social systems, practices and programme activities, as part of management concerns. The study compiled relevant views on conservation and protection practises which were in line with internationally accepted norms and practises on biodiversity management. It highlights the challenges of current practises which emphasise strengthening of legal frameworks, policies and practises, and which criminalise actions that contravene ideally-construed conservation precepts as best models of addressing biodiversity loss. It further discussed the emphasis placed on protected-area systems as the main model of biodiversity conservation and argued on the need to rethink the approach within the Nigerian context. The study articulates the role of sociology in ecological discourse and argues that although the knowledge gained by physical and biological sciences are essential in addressing ecological challenges, however, they are not sufficient to understand the driving forces underlying ecological challenges and the phenomenon fundamental to understanding trends and patterns of human factors in biodiversity loss. The study was explored within the methodological framework of phenomenology as the underpinning paradigm using a qualitative approach for analysis. The layouts of the thesis ensure that the research moves from theoretical and conceptual reflections to the actualities of lived realities and situated practices embedded in biodiversity management in Nigeria. The conceptual inclination for the theoretical base for the study analysis was postulated, which articulate the study’s scientific and empirical contributions. The survey method reflects exploratory analytical inquiry which supported the study’s methodological considerations. This was based on the specific data chosen for review, which was informed by the selected organisation’s application of social-construct concepts. Considered from a national perspective, the study assumed that issues of biodiversity management concerns were not to be separated from everyday social realities and the larger social challenges. In view of this consideration, the study analysis looked at historical, political and socio-economic backdrops in Nigeria, which reflected on bioresource-use practises. These are relevant to understand the dynamics and interplay of culture and values in bioresource-use patterns. The study builds on diverse arrays of global frameworks to integrate the major findings of the study. These were compared with related and different dimensions as well as existing theories of human-bioresource interactions. The first aspect of the empirical analysis explored conceptual dimensions which raised questions concerning perceptions of reality and social values that were linked to the strategies of social-constructs expressed through policies, plans and practices. The study’s fundamental empirical dimension explored the forms in which programmes and social institutions were relevant in ensuring behaviour change towards sustainable bioresource-use practise. The analytical sequences observed trends which support facilitation of social change through behaviour change. Another aspect of the empirical analysis focused on revealing the processional dynamics of programme activities to achieve set objectives. This was analysed from the methodical perspective of how the processes were monitored and measured in order to achieve anticipated outcomes. The study summarised the findings and the outcomes by outlining the themes which emerged from the research. The study analysis argued that the ideals of social interventions cannot be different from a society’s inherent and attributed meanings to realities, as well as how they engage with their everyday realities.

The first aspect of the empirical analysis explored conceptual dimensions which raised questions concerning perceptions of reality and social values that were linked to the strategies of social-constructs expressed through policies, plans and practices. The study’s fundamental empirical dimension explored the forms in which programmes and social institutions were relevant in ensuring behaviour change towards sustainable bioresource-use practise. The analytical sequences observed trends which support facilitation of social change through behaviour change. Another aspect of the empirical analysis focused on revealing the processional dynamics of programme activities to achieve set objectives. This was analysed from the methodical perspective of how the processes were monitored and measured in order to achieve anticipated outcomes. The study summarised the findings and the outcomes by outlining the themes which emerged from the research. The study analysis argued that the ideals of social interventions cannot be different from a society’s inherent and attributed meanings to realities, as well as how they engage with their everyday realities.

A sociological analysis of the production, marketing and distribution of contemporary popular music by Zambian musicians
- Authors: Kazadi, Kanyabu Solomon
- Date: 2015
- Subjects: Popular music -- Zambia , Musicians -- Zambia , Sound recording industry -- Zambia , Popular music -- Production and direction -- Zambia , Popular music -- Marketing , Intellectual property -- Zambia , Copyright -- Royalties -- Zambia

- Description: The purpose of this research was to gather information about the production, marketing and distribution of Zambian contemporary music by Zambian musicians. Very little information has been documented about the development of the Zambian music industry, particularly from the perspective of those within the industry. As a result this study attempted to add to this knowledge. To achieve this Pierre Bourdieu’s theoretical concepts of ‘fields’ and ‘habitus’ were used to gain an understanding of what affects the creation of art forms such as music as well as the structures and underlying processes within the music industry. The concept of ‘fields’ usefully framed an explanation of the struggles and connections within the various fields in the industry and a view of the Zambian music industry in relation to the international industry. To gather the data necessary for this research a qualitative approach was utilised involving semistructured in-depth questionnaires from twenty-three interviewees. These interviewees were selected from various sectors of the music industry in an attempt to gain a holistic perspective of the industry in the 21st century. There were four subgroups: the artists (singers, rappers and instrumentalists), managers, radio DJs, and a miscellaneous group made up of the remaining participants, a Sounds Arcade manager, a music journalist, the National Arts Council Chairperson, a Zambia Music Copyright Protection Society (ZAMCOPS) administrator, and the then President of the Zambia Association of Musicians (ZAM). With the limited exposure to formal musical, instrumental and production training, musicians, instrumentalists, managers and studio production personnel interviewed had had to learn their craft on-the-job. This limited knowledge appears to add to the hindrance of the development of careers and the industry, particularly in terms of how to register and distribute music correctly to earn royalties and protect their intellectual property against piracy. From an institutional level piracy is being addressed more forcefully with the introduction of holograms and the tightening of policies and structures to do with the music industry.

- Description: In 1854 Cayley proposed an interesting sequence 1,1,3,13,75,541,... in connection with analytical forms called trees. Since then there has been various combinatorial interpretations of the sequence. The sequence has been interpreted as the number of preferential arrangements of members of a set with n elements. Alternatively the sequence has been interpreted as the number of ordered partitions; the outcomes in races in which ties are allowed or geometrically the number of vertices, edges and faces of simplicial objects. An interesting application of the sequence is found in combination locks. The idea of a preferential arrangement has been extended to a wider combinatorial object called barred preferential arrangement with multiple bars. In this thesis we study barred preferential arrangements combinatorially with application to resistance of certain electrical circuits. In the process we derive some results on cyclic properties of the last digit of the number of barred preferential arrangements. An algorithm in python has been developed to find the number of barred preferential arrangements.

- Description: The study focussed on the effectiveness of control measures for dealing with absenteeism of educators with specific reference to selected schools at Libode District in the Province of the Eastern Cape. It identified the policy framework including rules and regulations relating to the absenteeism of educators. It assessed the effectiveness of control measures which are currently at the disposal of the selected schools and it also investigated the challenges faced by school principals in addressing the challenge of absenteeism of educators in the selected schools. A qualitative research methodology was used in undertaking the study. Purposive sampling was used to select the schools and participants for the study. Participants were comprised of school principals and Education Development Officers. Data was collected through structured and semi-structured interviews. Literature study showed that the management of educator absenteeism is an important aspect of Human Resource Management in schools. Furthermore, the study found that control measures for dealing with absenteeism are not properly applied in many schools and there is no consistency in the manner in which they are utilised by school principals. The study also found that school principals are struggling to manage absenteeism to the extent that some of them are not sure how to deal with educators who abuse leave. The study recommends that school principals should be empowered on leave management through various forms of training which include workshops.

- Description: According to Greenberg (2011) stress is an inevitable fact of organizational life today, and has an effect on both the employer and employee. The main aim of this study was on finding out the effect of job stress on job satisfaction and employee turnover in the Eastern Cape Provincial Legislature department. This study was conducted employing logical positivism as the philosophical paradigm; and this logical positivism derives from only two sources of knowledge which are logical reasoning and empirical experience. The researcher employed a non-experimental exploratory quantitative approach, employing the questionnaire as a data collection instrument. A sample size of 238 participants was used to collect data. Data analysis was done using the Pearson correlation coefficient and multi regressions. Job stress was found to have substantial influence to increase turnover intentions and to decrease job satisfaction. In addition, job stress and job satisfaction combine to have a collective influence on turnover intentions. The study recommends managers to implement motivational strategies to enhance job satisfaction and retain employees as long as possible.
