The single biggest challenge facing municipalities today is a shortage of funds and labor for upgrading and expanding aging infrastructure. This continued lack of funding impairs the municipalities ability to maintain desired levels of service. Over the last decade, many Canadian municipalities have faced pressures of increasing complexity in infrastructure asset management decision-making which can be partly attributed to cost escalation, increasing service demand and interdependencies between networks. The goal of this research is to develop the framework for Asset Levels of Service (ALOS)-based decision support systems for municipal infrastructure network investment. The proposed framework is based on the fact that ALOS should be one of the main criteria for municipal infrastructure maintenance, repair and rehabilitation (MR&R). Since ALOS is based on qualitative and quantitative parameters, the use of ALOS in municipal infrastructure MR&R decisions will result in improved funding allocation. Secondary parameters used for municipal infrastructure investment decision making in the proposed framework are the physical deterioration of assets, future growth and the impact on the dependent infrastructure network. The proposed framework focuses on funding allocation for the MR&R of municipal networks. The framework is applicable to municipal infrastructure networks, excluding the other assets such as buildings, parks, etc. Application of the proposed framework is demonstrated by its implementation in the case of urban roads. Implementation is carried out in four phases. Phase I involves the quantification of ALOS for urban roads. Quantification of ALOS for urban roads has various challenges such as multiple users and interdependencies of levels of services between various users. An Analytical Hierarchy Process (AHP) has been used to quantify ALOS. Phase II involves the determination of a multiattribute utility function for investment decision. Calculated multiattribute utility of investment decision is used in the multiobjective optimization model in Phase III. In Phase IV, the proposed methodology is incorporated into a computer application called OPTIsys (OPTImum Infrastructure SYStems). OPTIsys will facilitate MR&R decision making based on fully integrated considerations of ALOS, future demand and network interdependencies. Stakeholders benefiting from OPTIsys include the general public, asset-managers, infrastructure departments and municipal councils. OPTIsys will enable infrastructure departments to maintain the operational capability of the network in compliance with the targeted levels of service. Overall, municipalities will be able to reduce the infrastructure deficit while maximizing economic returns. / Construction Engineering and Management

Worldwide, changes in the family have become more evident. Many of the traditional roles that families used to play are now performed by other institutions, such as schools, churches, a variety of welfare agencies and non-governmental organizations. Families in South Africa are no exception, as many South African families are faced with challenges that have a negative impact on their ability to sustain themselves and their members. The previous Minister of Social Development, Doctor Zola Skweyiya, rightly acknowledged that, in order to address the needs of vulnerable groups in our communities effectively, we need a particular focus on the role of the family, both as a developmental and as a supporting institution. In responding to these challenges, the Department of Social Development developed a new Manual on Family Preservation Services (Department of Social Development, 2008b), with the aim of training social service professionals to deliver family preservation services. In order for the programme envisaged by the developers of the Manual to be implemented efficiently, the Norms and Standards Policy on Developmental Social Welfare Services (Department of Social Development, 2007a:52-57) mandates the roll-out of the training and education by all provinces. Thus all social service professionals are mandated to implement family preservation services as stipulated by the Norms and Standards Policy on Developmental Social Welfare Services (Department of Social Development, 2007a) and the Draft National Family Policy (Department of Social Development, 2008a). In her role as one of the trainers on family preservation services who was also responsible for monitoring and evaluating these services in the provinces, the researcher observed the inadequacy and inconsistency of the concept of family preservation services in reporting among social service professionals despite the training and capacity-building carried out by the Department of Social Development. The researcher therefore investigated, first, whether the formulation of the Manual on Family Preservation Services lacks clarity relating to the theoretical framework and operational definition of key concepts which are supposed to assist social service professionals in rendering effective family preservation services. Second, she interviewed 20 social workers regarding their experiences on the formulation and implementation of the Manual. This is a small sample in terms of representing social workers in the country. In total, 37 social workers were originally interviewed, but, because it transpired that they had never attended any training on the Manual for Family Preservation Services, their data were excluded from the empirical study, even though they are implementing these services. The researcher was therefore interested in analysing the formulation of the Manual on Family Preservation Services and also analysed the experiences of social workers regarding the formulation and implementation of the Manual, with the aim of identifying gaps and improving service delivery to families. The researcher reviewed prior literature on systems theory, which is fundamental in addressing family dynamics, the family life cycle and its stages. She also considered literature on family preservation services on four levels of service delivery, the stages of the policy cycle and the overview of the Draft National Family Policy, as well as the Manual of Family Preservation Services. In this study, the researcher adopted an explanatory design, which is a form of mixed methods research. The overall purpose of an explanatory design is to gather qualitative data that help to explain or build upon initial quantitative results from the first phase of the study. In order to collect quantitative data, the researcher used a checklist for a content analysis of the formulation of the Manual on Family Preservation Services. She then conducted semi-structured interviews to collect qualitative data about social workers’ experiences regarding the formulation and implementation of the Manual on Family Preservation Services in eight provinces. The researcher did a pilot test of the semi-structured interview schedule, which helped her to refine two questions that were understood differently by the two social workers who participated in the pilot test. After latent coding, the quantitative data were analysed manually, while the qualitative data were coded according to Creswell’s model for qualitative data analysis. The quantitative empirical results revealed some limitations in the formulation of the Manual on Family Preservation Services. Such limitations include an unclear definition of the concept of family preservation services, the omission of objectives from the Manual, confusion with regard to the theoretical frameworks applied, a lack of clarity on the role of volunteers, the process of providing training and capacity-building to social service professionals, monitoring and evaluation plan. These findings were confirmed by the social workers who were interviewed. They exposed the confusion that exists on the definition of family preservation services, the objectives, the theoretical frameworks, the role of volunteers, high case-loads, which they linked to a shortage of social workers and the fact that resources, training and capacity-building on family preservation services are not prioritized. It was therefore recommended that the issues highlighted above be addressed and be included in a revised Manual, and that relevant material also be provided to social service professionals who need to implement family preservation services. / Thesis (DPhil)--University of Pretoria, 2009. / tm2015 / Social Work and Criminology / DPhil / Unrestricted

Within the design of any building, there is a requirement for designers to understand the intended purposes of the building and the elements that influence performance. These elements can be as tangible as providing a lecture hall within a university or relatively intangible such as the environmental temperatures of the rooms. The elements involved are generally recognised within the design industry and a combined force of engineers, architects, and specialist advisors work together to ensure all of the elements are in place for each new design. However, one element affecting performance that has not yet been comprehensively covered (at least for many building types) is that relating to occupant movement and the influence this has on experience and hence performance. For example, the number of times people have to negotiate cross-flow environments in a train station before becoming agitated is unknown. Also, the average distance people will walk through a shopping centre before becoming tired and ending the activity is unknown. Even so, they will both be impacted upon by the design and they will both reflect back on the performance of the design. Before starting this research, it was realised by the research engineer that there was only a limited understanding and application of people flow analyses within industry and, where it existed, it was solely related to transport terminals, pedestrian walkways/crossings, sports stadia arrivals/egress, and evacuation analyses.

Effective and satisfactory security service is critical to private security officers (PSOs) working in the private, state-owned and public sectors as it plays a pivotal role in improving organisational productivity and helps to promote good working relationships. When PSOs project poor attitudes, clients are seriously affected by such negative behaviour and the level of service rendered will eventually deteriorate. This study sought to understand and explore the factors that contributed to unsatisfactory services rendered by PSOs at GPW in Tshwane. The researcher utilised a nonexperimental quantitative research approach and a self-administered questionnaire survey was used to collect data. Data collected was analysed and interpreted using quantitative methods and procedures. The findings emanating from the research revealed that the levels of service rendered by PSOs at GPW in Tshwane was ineffective and unsatisfactory and various factors contributed to ineffective service delivery. Several recommendations are proposed to improve the level of service rendered by PSOs. / Criminology and Security Science / M. Tech. (Security Management)
