- Description: The effect of the inclusion of sexual behaviour, particularly three sexual orientation classes, on the transmission dynamics of HPV and cervical cancer incidence was investigated. A comprehensive literature review of mathematical models of HPV transmission and the natural history of cervical cancer was concluded. A mathematical model using ordinary differential equations was developed, which incorporated the three sexual orientation classes, and a sexual mixing algorithm for modelling the transmission dynamics. Reproduction numbers, determined through a simplified version of the developed model, indicated that the bisexual population could form a bridge between the heterosexual and homosexual population. The level of interaction is determined by the selection preferences of a bisexual individual to form a partnership with an individual of the same or opposite sex. The model was simulated, with parameters based on a South African population and HPV type 16/18, to investigate the effects of HIV status, sexual orientation and various vaccination strategies on HPV transmission and cervical cancer incidence. The results indicated that HIV status is a significant factor when determining cervical cancer incidence. The results regarding vaccination strategies agreed with results from the literature review with a two sex before sexual debut and catch up program the most effective, noting that with increased vaccination coverage of females the marginal impact on cervical cancer incidence of this approach diminished.

- Description: Pre-print , This article represents the next in a series of five-year overviews of children’s rights in the courts in South Africa. Using the Convention on the Rights of the Child and the African Charter on the Welfare of Children as a point of departure, the study suggests that it is in the public sphere that children’s rights have had their most impact in the period under review. The article highlights eight areas of distinction in this five-year period: these include judicial approval of resource mobilisation for the fulfilment of children’s rights, emphasis on the quality of and standards in education; the development of innovative remedies to deal with unreasonable state measures affecting children, and an increasing focus on the right to dignity of the child. The authors conclude that the scope of the cases cited points to the growing insertion of children’s rights considerations in increasingly diverse areas of legal interaction. Furthermore, the authors posit that the CRC and ACRWC – together with non-binding sources of international law – have substantively informed and enriched the jurisprudence of South African courts.

- Description: Mentoring is a powerful developmental tool that can be utilised in organisations to enable learnerships to learn various skills – hard and soft – that will enable them to become more equipped for the workplace. The hard skills refer to technical competencies, e.g. computer literacy, and soft skills refer to competencies such as interpersonal skills, communication skills, work etiquette, etc. Mentoring is no quick fix to filling all the gaps within a learnership, but it can add significant value to have a formal mentoring strategy within organisations to transfer much needed skills and competencies. The literature on mentoring provides many examples of possible strategies, and in this research project, the competencies of both mentor and mentee were highlighted, together with the advantages, disadvantages, myths and challenges in formal mentoring strategies. The process of developing a mentoring strategy is not complex, but requires support and involvement from various stakeholders to ensure the sustained success of a mentoring strategy. The different models of mentoring strategies in the literature review provided a framework for the researcher to develop a mentoring strategy that was tested through the completion of questionnaires sent to organisations that employ learnerships. The research study rated the responses of the respondents on the suggested model and various steps to be followed in the process. The research study concluded with a formal mentoring strategy or model that can be used within organisations that employ learnerships.

- Description: Although there are several Software Development kits and Application Programming Interfaces for client-side location-based services development, they mostly involve the creation of self-referencing location-based services. Self-referencing location-based services include services such as geocoding, reverse geocoding, route management and navigation which focus on satisfying the location-based requirements of a single mobile device. There is a lack of open-source Software Development Kits for the development of client-side location-based services that are cross-referencing. Cross-referencing location-based services are designed for the sharing of location information amongst different entities on a given network. This project was undertaken to assemble, through incremental prototyping, a client-side Java Micro Edition location-based services Software Development Kit and a Mobicents location server to aid mobile network operators and developers alike in the quick creation of the transport and privacy protection of cross-referencing location-based applications on Session Initiation Protocol bearer networks. The privacy of the location information is protected using geolocation policies. Developers do not need to have an understanding of Session Initiation Protocol event signaling specifications or of the XML Configuration Access Protocol to use the tools that we put together. The developed tools are later consolidated using two sample applications, the friend-finder and child-tracker services. Developer guidelines are also provided, to aid in using the provided tools.

- Description: Since the beginning of the millennium there has been a drive by organisations to achieve more with fewer resources. This has been heightened further by the global financial recession which has both direct and indirect effects on South Africa. Employee engagement has now become a critical business issue as the economic landscape becomes increasingly turbulent and organisations need coherent strategies to maintain their competitive advantages. Employee engagement is a business management concept that is particularly relevant to organisations that leverage off human capital and involves the maximising of individual commitment to and satisfaction with work. When the current healthcare environment is taken into consideration, with its dire shortage of medical doctors, a human resources scheme that has employee engagement at its heart must be considered an imperative by medical organisations. Upon embarking on the research into the topic it became evident that there was a scarcity of investigations into employee engagement as it applied to physicians. The purpose of this treatise, then, is to examine the key drivers of employee engagement in emergency medicine doctors and develop an engagement model that can be used by organisations to enhance this positive psychological state for their good, the good of the medical doctor and, in due course, for their patients. In order to achieve this goal a thorough literature review was performed which drew on both academic and practitioner sources of information into the concepts of employee, knowledge worker and physician engagement. This led to the development of a hypothesised model which was tested using rigorous measures incorporating questionnaire-style, quantitative data collection and statistical analysis. The results of the research show that communication; work-life; company alignment; growth and development; recognition and reward; management support; autonomy; and mission and purpose are all closely associated with the construct of employee engagement. Work-life and company alignment, in particular, were shown to have direct positive associations with the concept and are postulated to be key areas for emergency medical organisations to focus their attentions in the quest for engaged and motivated doctors. Ultimately, employee engagement is shown to be valuable, measurable and actionable. The devised model for employee engagement in emergency medical doctors can be utilised in the harnessing of physicians hearts and minds to the work that they love doing and the organisations that they love doing it for. This is a win-win result for all of the important stakeholders of healthcare in South Africa.

- Description: New innovative products are being designed while the user interface of existing products is constantly being revamped to give them a new look. All this is an effort to bring a satisfactory interacting experience for the user. However, in most cases users do not feel that they experience that benefit. The introduction of a new product, or the enhancement of the functionality and user interface of an existing product, often faces criticism and brings resistance to the acceptance and usage of the product by the users. Therefore, the change in user interface or introduction of new products does not only affect the business processes but also the lifestyles of the users, as well as their overall user experience. One of the most important components for the success of any product is a positive user experience. User experience refers to the subjective feeling of the user that results from their interaction or intention to interact with a product in order to perform a specific task in a specific environment. When the user interface and functionality of a product match the expectations of the users and make the users effective and efficient, feel safe and attain some level of self-worth from using or possessing the product, their interaction with the product becomes more satisfactory. User experience practitioners are in agreement that a change to the user interface influences the user experience of the people when interacting with the product; hence it affects change in the user experience of the people. A vast body of literature exists on the methods for evaluating user experience as well as on the principles that are aimed at guiding the design of products for a positive user experience. However, there is a lack of a means to manage this change in user experience that results from the changes in the features of the user interface or the product functionalities. This inadequacy opens up the potential for integrating change management principles in order to manage user experience. However, existing change management principles do not address the user experience aspects when managing change. Following the above premise, this study focused on the development of a model for managing user experience: the User Experience Management Model (UXM2). The UXM2 infers its components from the disciplines of user experience and change management. Its uniqueness is seated in its people-centred approach that aims to effect a free-will change in the individuals towards a long-term positive user experience. The proposed model further aims to promote the voluntary acceptance of a product, which is contrary to the mandatory change that is guided by the policies of the organization, as discussed in the study. The UXM2 was developed from a thorough argumentation of literature on user experience and change management. The components that were required for development of the model were identified from literature, and were evaluated for their relevance by means of academic publications in subject domain international conferences. The academic publications underwent double-blind peer review with subject domain experts. The model was evaluated for its relevance and potential applicability through interviews and discussions with subject domain experts. The subject domain experts consist of user experience practitioners and academic professionals in the domain of HCI. The subject domain experts also evaluated the model by means of an evaluation tool comprising of a Likert scale rating of the proposed components and related activities for managing user experience. The target users of the UXM2 are user experience practitioners and product developers who aim to promote a sustainable long-term positive user experience for the people interacting with their products. The UXM2 is aimed at being used for the design of products that are meant for institutional use, personal use, mandatory use and optional use. It is believed that adoption of the UXM2 will promote acceptance of the product by users, with an associated sustainable positive long-term user experience.

- Description: University sustainability is a field of research that has been gaining increased interest in recent years. The reduction of environmental impact has become a strategic objective of universities globally. Universities have been prompted to take necessary action to ensure that their environmental impact is at a minimum. The environmental component of sustainability deals with the current conservation of the earth’s natural resources so that future generations can also have access to them. Human beings, due to their increasing needs, are accountable for the exploitation of natural resources. They are regarded as the main contributors to imbalances in the natural systems. Environmental concerns such as global warming, deforestations, disposal of wastes, and ozone reduction are the outcomes of the damage caused by humans on the environment. The aim of environmental education is to acquire remediation of the environment by making individuals aware of the environment and by educating them about how to live a more sustainable lifestyle. Environmental awareness is perceived as knowledge of the factors that affect the environment and having sensitivity towards the environment. Higher Education Institutions (HEIs) bear the responsibility of educating individuals about environmental issues since they provide education to future leaders in society who may have an influence on future conditions in the environment. Social media are capable of delivering information to a large spectrum of audiences at a low cost. The Pew Internet American Life Project reported that the number of adults who utilise social media has increased by 57 percent from 2005 to 2011. Several environmental activist organisations utilise social media to carry out environmental awareness campaigns. In this study two environmental awareness campaigns which were powered by social media were conducted to improve environmental awareness of individuals in a higher education environment. A Social media Model for ENvironmental Awareness (SMENA) was developed to facilitate the environmental awareness campaigns. The SMENA includes a website, social media as well as theoretical guidelines for creating environmental awareness campaigns, and for using social media for environmental awareness campaigns. A case study at the Nelson Mandela Metropolitan University (NMMU) was used to empirically evaluate SMENA. Students at the Department of Computer Sciences of NMMU were exposed to information about environmental issues through social media with the intention of improving their environmental knowledge and awareness. The SMENA website usability was rated positively and students enjoyed the blogs and information distributed by means of social media. The results of the study intervention were positive and showed that social media can be used to improve the environmental knowledge of students. This study provides a valuable contribution to both the field of environmental education and social media usage and acceptance. The guidelines and requirements for using social media to improve environmental awareness provided in this study can be used to assist educators and university management with addressing the problems of reducing environmental impact.

- Description: The main purpose of this research was to evaluate the processes for IQMS implementation in the selected Eastern Cape schools so as to determine the model that can be postulated for improving the IQMS implementation in the South African schools. While mainly deriving from the fact that so far, empirical research reveals that the process for IQMS implementation has been marred with a significant number of challenges. The study star begins with the formulation of a thought-process in its overriding hypothesis. The hypothesis is that the application of a five constructs’ IQMS Implementation Model in Figure 1.1 would signficantly influence the successful IQMS implementation in South African schools. The five constructs that are outlined in the IQMS Implementation Model in Figure 1.1 include: (1) Considering the Notion of “Quality” and Whole School Evaluation, (2) Performance Management and Developmental Appraisals, (3) Considering Key Success Factors for IQMS Implementation, (4) the Use of Appropriate Implementation Processes, Systems and Methods, and (5) Constant Monitoring, and Evaluations and Applications of the Improvement Actions. Despite the fact that the integrated quality management theories strongly support this hypothesis, the study, in line with these five constructs which were also aligned with the five research questions and hypotheses that guided this research applies exploratory factor analysis. This has been done in order to further define the structure of the IQMS Implementation Model in Figure 1.1 prior to applying confirmatory factor analysis in order to determine whether the IQMS Implementation Model in Figure 1.1 would perfectly reproduce the 53 observed sample data which was used in the study. The results confirmed the overriding hypothesis in the IQMS Implementation Model in Figure 1.1 which is that effectiveness of the IQMS implementation processes in the South African schools can be significantly influenced by the application of the five constructs. These include: Considering the Notion of “Quality” and Whole School Evaluation, Performance Management and Developmental Appraisals, Considering Key Success Factors for IQMS Implementation, the Use of the Appropriate Implementation Processes, Systems and Methods, and Undertaking Constant Monitoring, Evaluations and Improvement Action. In effect, it was recommended that the Eastern Cape Department of Education must adopt the IQMS implementation Model in Figure 1.1 in order to effectively implement its integrated quality management systems. Despite examining the limitations of the study, the recommendations chapter also discussed the area for further research in which it was suggested that the area for further research would be: Evaluating the impact of appropriate standards’ setting on the successful IQMS implementation in the schools in the Eastern Cape schools.

- Description: Judith Butler’s theory of performativity provides gender theorists with a rich theoretical language for thinking about gender. Despite this, Butlerian theory is difficult to apply, as Butler does not provide guidance on actual analysis of language use in context. In order to address this limitation, we suggest carefully supplementing performativity with the notion of performance in a manner that allows for the inclusion of relational specificities and the mechanisms through which gender, and gender trouble, occur. To do this, we turn to current developments within discursive psychology and narrative theory. We extend the narrative-discursive method proposed by Taylor and colleagues, infusing it with Butlerian theory in order to fashion a dual analytical lens, which we call the performativity-performance approach. We provide a brief example of how the proposed analytical process may be implemented.

- Description: This study focuses on the perception of teachers who have depressed adolescent learners in their classrooms as well as explores how teachers cope with teaching depressed adolescent learners in their classrooms. For the purpose of this study, a qualitative research method was employed. Data was collected in the form of twelve semi-structured interviews with teachers in order to ascertain their perceptions on including and accommodating depressed adolescent learners in their classrooms. The data was analysed for emerging themes and sub-themes according to Tesch‟s eightstep data analysis process. This study highlights the characteristics, symptoms and causes of depression in adolescents and the effect it has on learners within our educational system. The results of the study indicate that the inclusion of depressed adolescents in the classroom can be problematic for teachers since they feel that they are not suitably trained to deal with these learners in a teaching and learning environment. The participating teachers indicated that they are not able to identify and support depressed adolescent learners in their classrooms effectively. The participating teachers feel that they require further training on how to refer these depressed adolescent learners and their parents for further intervention and support. Based on the findings of this study, the researcher constructed guiding principles in order to address the issues raised by the participating teachers. In the light of the guiding principles, recommendations were made towards teachers, parents, schools, health professionals, the Department of Education, the Department of Health and further research in order to accommodate depressed adolescent learners in South African schools effectively.

- Description: Rural development can be supported by information and knowledge which are key strategic resources for socio economic development. ICTs enable the facilitation and communication of information between remotely dispersed individuals or groups and more developed regions. While it has become common place that ICTs possess capabilities to potentially support rural development, the concept of ICT for development (ICT4D) is still fraught with challenges and barriers, which impede the success and sustainability of ICT4D projects. It is therefore essential to evaluate rural ICT projects, as such an analysis may aid in revealing information related to the need, effectiveness, impact, and sustainability of these projects. This research seeks to further the implementation and exploration of the Rural ICT Comprehensive Evaluation Framework (RICT-CEF), through the application of the Process Assessment domain in a real life rural ICT project environment. The RICT-CEF framework consisting of 7 evaluation domains has the primary objective of evaluating rural ICT projects from their inception stages to post implementation. A process assessment seeks to determine whether or not a rural ICT project is operating to implement its intended functions in the intended way specified in the projects plan. Such an assessment is invaluable to a comprehensive evaluation. Evaluation questions for a process assessment are centred around critical themes of project performance. Critical themes are aspects of a programme or projects implementation which must be enacted in order to achieve desired project outcomes. This research study is aimed at identifying critical themes of process assessment relevant to rural ICT4D projects. To identify critical themes, assessment approaches on social programme process assessments, evaluation of information systems in use, and rural ICT4D project evaluation case studies are comparatively analysed. Fourteen assessment approaches from these three categories are selected based on criteria. To analyse selected assessment approaches, a template is created based on the research questions, foundational literature on process assessment and identified challenges applicable to process assessments of rural ICT4D projects. Comparing and contrasting critical themes from these assessment approaches highlight critical themes essential to assess in the iterative implementation phase of rural ICT projects. Accentuated critical themes include, service utilization, organizational function and external project factors. These themes, along with suggested guiding principles from literature for conducting process assessments enable the creation of a framework for conducting process assessments of rural ICT projects. The framework is labelled "the Rural ICT Project Process Assessment Framework (RICTP-PAF)". The application of the RICTP-PAF in a real life rural ICT project through a design science case study provides lessons learned (suitability and shortcomings) from applying the framework. This essentially demonstrates the sensitivity of the RICTP-PAF to rural contexts in which it is implemented in. For instance, the implemented prototype of the RICTP-PAF reveals that the framework places a great deal of emphasis on rural beneficiary perspectives. A practice which has been lacking in such evaluation exercises. Furthermore, the guiding principles elucidated, bring to mind best practices to deal with issues such as stakeholder conflict, unreliable data elicitation and unethical assessment practices. The RICTP-PAF represents a fundamental tool for process assessments of rural ICT projects, and may be adopted and customized to various rural ICT project contexts in developing countries.

- Description: The current study is a psychobiography. The subject was chosen through purposive sampling based on the researcher’s personal interest and the remarkable impact this woman had within her society. Ellen Kuzwayo also meets the requirements of a psychobiography in that she is historically well known, inspirational, and her life has been completed. The study applies a qualitative research method in the form of a psychobiography, which aimed to describe Ellen Kuzwayo`s life accordingto Daniel Levinson`s Life Structure Theory of Adult Development. Levinson`s theory divides the lifespan into four developmental eras, each with its own biopsychosocial character. Each era in turn is divided into shorter periods of development. Levinson`s theory was chosenbecause it is specifically relevant to the development of women. The findings of the study indicate that Kuzwayo’s life was consistent with the pattern of development which Levinson (1996) identified. Kuzwayo was relatively successful in resolving the life tasks and transitional periods proposed by Levinson. This research study has given a positive demonstration of the value of development theory to investigate a particular human life. Furthermore, it emphasized the uniqueness of individuals in coping with the challenges of life. As a result it has opened up the possibility of perceiving people and their actions in a different way. Consequently, recommendations are offered in order to extend psychobiographical research on the life of Ellen Kuzwayo.

- Description: Martin Luther King Junior was an advocate of non-violent social change strategies; he was a pastor, an author, the first president of the southern Christian leadership conference, a speaker, a Nobel Prize winner, and a leader. Martin Luther King junior was transformed by his deep family roots in the African American Baptist church. His formative experiences in his hometown of Atlanta were his theological studies, his varied models of religious and political leadership and his extensive network of contacts in the peace and social justice movements of his time. Although only 39 at the time of his death, Martin Luther King juniors’ life was remarkable for the ways it reflected and inspired so many of the twentieth century’s major intellectual, cultural and political developments. The primary aim of this study was to explore and describe the psychological development across the lifespan of Martin Luther King junior, by applying Alfred Adler’s theory of individual psychology. Martin Luther King junior’s life was explored in this study through systematic collection, analysis and interpretation of the historic data on his life, which highlighted seven significant historical periods: (a) Childhood and adolescence (1929 – 1944), (b)The inevitable (1944 – 1948), (c) The Purpose in his Destiny (1948 – 1951), (d) Family and mission (1952 – 1959), (e) Movement against segregation (1960 – 1963), (f) History is made (1963 – 1967), and (g) Unfinished business (1968). Adler’s framework was used to recognize, convert and reconstruct his life into a coherent narrative of his psychological development throughout his life. Alexander’s guidelines for extracting salient data was utilised to ensure accurate description of Martin Luther King junior’s life. A conceptual framework that is the Adlerian Matrix was included in the study as guide in presenting the research discussion and findings in an illuminating and integrative manner. The research discussion and findings suggested that Adler’s theoretical framework considers the biopsychosocial, cultural and historic influences in Martin Luther King junior’s personality development. In taking the context into consideration, Adler’s individual psychology identified King junior with a social useful lifestyle because of his high social interest which influenced his striving for superiority. This lifestyle guided his fictional goal which was selfless and aimed at contributing to the wellbeing of others. The private logic about himself, others and the world, which is developed in early childhood, was a positive navigator for the development of his personality and lifestyle. Thus according to the Adlerian theory, King junior could positively balance the resolution of the life tasks of occupation, social and love & marriage. The study of King junior’s personality development has provided an affirmative demonstration of the value of Adler’s psychological theory to understand the process of personality development in an individual life. It has highlighted the value of studying an individual life taking his context, including early experiences, family environment and every action, into consideration to understand the uniqueness of responding to life tasks and his perceptions. Recommendations were made for future research undertakings using psychobiographical research design and methodology to reveal, illuminate and reconstruct the lives of historic personalities

- Description: The proposed study is of a psychobiographical nature and employs a qualitative research approach. The individual that forms the subject of this study is William Wilberforce. A social activist most of his life, Wilberforce is best known for his voice and works behind the abolition of the slave trade in 1807 and the abolition of slavery in 1833. His ambitious nature, social eloquence and verbal intellect resulted in him being elected as a member of parliament in the House of Commons in England during the period 1780 to 1825. Transformed by the Christian faith in 1885, Wilberforce came to the realization he had received a calling from God to speak up for those who could not with a specific task set out before him which was to abolish slavery. It was the purpose of the present research to explore and describe Wilberforce’s psychological development across his life-span according to Carl Rogers’ (1961) personality theory of optimal development. Salient aspects of Wilberforce’s life were related and compared to components of the theory so as to explore and describe the degree of optimal development that Wilberforce reached at different points in his life and whether he could be described as a fully functioning person. According to Rogers’ theory William Wilberforce was chosen as the research subject for his historical contribution to mankind by his devotion to the moral enhancement of his country.

- Description: 1. This study outlines the development of a qualitative risk assessment method and its application as a screening tool for determining the risk of establishment and spread of the invasive Nile tilapia, Oreochromis niloticus (Linnaeus, 1758), within the central sub-catchment of the Limpopo River basin in northern South Africa. 2. The assessment used known physiological tolerance limits of O. niloticus in relation to minimum water temperature, presence or absence of dams, seasonality of river flows, and the presence of indigenous fish species of concern to identify river systems that would be suitable for O. niloticus establishment. 3. River sections along the Limpopo main river channel and the immediate reaches of its associated tributaries east of the Limpopo/Lephalala river confluence along the Botswana–South Africa–Zimbabwe border were identified as being highly vulnerable to O. niloticus invasion. Rivers in the upper Bushveld catchment (Upper Limpopo, Mogalakwena, Lephalala, Mokolo, Matlabas and Crocodile rivers) were categorized as of medium ecological risk, while headwater streams were considered to be of low ecological risk. The decrease in vulnerability between lowveld and highveld river sections was mainly a function of low water temperatures (8–12˚C) associated with increasing altitude. 4. Oreochromis niloticus is already established in the lower catchment of the Limpopo River basin where indigenous congenerics are at an extinction risk through hybridization and competition exclusion. Oreochromis niloticus, therefore, poses an ecologically unacceptable risk to river systems in the upper catchment where it is yet to establish. The current risk assessment model provides a useful preliminary framework for the identification of river systems that are vulnerable to an O. niloticus invasion where conservation measures should be directed and implemented to prevent its introduction and spread within the Limpopo river system.

- Description: This research study describes an evaluation of social work field instruction offered by universities in the Eastern Cape, South Africa. Qualitative data was collected from agency field instructors, university fieldwork coordinators and social work students. This study’s findings indicated that field instruction needs a good foundation of experiential learning that is facilitated by report writing, journal writing and agency and university supervision. Findings also indicated a need for the screening, selection and training of agency field instructors. There was also an indication that universities should develop selection procedures to ensure that the best possible students are accepted into the Bachelor of Social Work (BSW) programme. All findings indicated that field instruction programmes are most effective when there is a strong university agency partnership. The study concludes by making recommendations for future development of standards relating to field instruction programmes in the Eastern Cape and South Africa. Key words: Social work, evaluative research, field instruction, experiential learning, reflection, agency field instructor, university supervisor, university fieldwork coordinator, social work student, social work education, social work training.

- Description: This mini-dissertation, aims to review tribal armed conflict resolution in selected Counties in Lakes State, South Sudan. The objectives of the study were to find out the consequences of the tribal armed conflicts on governance and service delivery and strategies to mitigate peace and tribal armed conflict resolution in order to enable development in the selected counties of Lakes state. Quantitative and qualitative data was collected from a sample of three hundred and ten (310) respondents who included the County Commissioners, Judges and Magistrates, Law enforcement officers, local government officers and traditional leaders through questionnaires and interviews. The study sought to review the effects of tribal armed conflicts on service delivery in the selected communities. It further examined conflict resolutions mechanisms and strategies that have been used by various actors and stakeholder to ameliorate tribal armed conflict in Lakes State, South Sudan. The results of the study showed that ethnicity in conflicts in South Sudan has played a significant role and has posed many challenges to scholars, political leaders, appointed public officials and communities alike. Some of the challenges include; tribalism, ethnic conflicts, and struggle over scarce resources. This has often led to rampant underdevelopment, under-representation in governance; unemployment and poverty, among administrative perils and dysfunctions that have subsequently been major drivers of tribal armed conflicts. Many youth who are unemployed are often involved in cattle raiding, hence revenge attacks often lead to frequent tribal armed conflicts. The study recommends that effective and sustainable peace building can be achieved through empowerment of the communities and use of traditional strategies in tribal armed conflict resolution in Lakes State. This is because external players often attempt to engage in peace building activities without seeking sustainable solutions at the grassroots level. Very often conflict resolution has been the preserve of NGOs and diplomats, who have no intimate acquaintance with local contexts. The study suggests that provision of services to the people through sustainable development of the rural areas and through the creation of alternative forms of livelihood, such as jobs, has to engage with and include the youth in economic development, so that tribal armed conflicts are ameliorated.

- Description: publisher version , A set of eight-membered benzannelated heterocycles containing two heteroatoms (O,O, NR,NR and O,NR where R=protecting group) was synthesized by ring-closing metathesis from the corresponding ortho-bis-allyl precursors. In this manner, 7-methoxy-2,5-dihydro-1,6-benzodioxocine, 1,2,5,6-tetrahydro-1,6-benzodiazocines, 5,6-dihydro-2H-1,6-benzoxazocines and 5,6,9,10-tetrahydropyrido[2,3-b][1,4]diazocine were synthesized. A number of these compounds were then treated with the catalyst [RuClH(CO)(PPh3)3] to facilitate isomerization of the alkene into conjugation with the heteroatoms in the eight-membered ring. Quite surprisingly, an equal ratio of regioisomers was obtained, even if the heteroatoms were different.
