South Africa faces a shortfall in its provision of housing for low income households. This study explores the potential to use public private partnerships (PPP) to address these supply problems. A review of the housing market and an examination of the opportunities and challenges presented by PPP are presented, including a review of the international experience in the provision of social housing. Interviews with key stakeholders are undertaken to evaluate the appropriateness of PPP in the South African social housing sector. PPP are believed to have the potential increase the supply of social housing, provided there is continuing support from the state. However, none of the key stakeholders were keen to use the “traditional” PPP process, suggesting a need for innovative partnership models more appropriate for the sector.

Dagens företag vill ge anställda möjlighet att jobba hemifrån eller på resande fot. En vanlig lösning för att möjliggöra detta är virtual private network (VPN). VPN ger en användare tillgång till interna resurser på företaget från ett externt nät, exempelvis via Internet. Detta gör att användare kan komma åt de interna resurserna på ett säkert sätt. Vilken VPN-teknik är då att föredra för att få en så snabb, säker och pålitlig anslutning som möjligt? Detta examensarbete tar upp olika VPN-tekniker. Vi beskriver vanliga VPN-protokoll som L2TP, IPSec och PPTP. Hur användare autentiseras på ett säkert och smidigt sätt samt metoder att göra sin VPN-anslutning säker. Vi redovisar också den lösning vi har implementerat hos Confidence, för vilka arbetet utfördes. Problemen med att använda de produkter som redan fanns på företaget beskrivs. Förslag på lösningar ges för att lösa dessa problem i framtida arbeten. / Companies of today want to give their employees the opportunity to work from home or while they travel. A common solution to accomplish this is to implement a VPN over top of the existing network. Using VPN gives the employees access to the company’s local area network from outside, via the internet. The VPN provides a secure channel for these employees to connect to the local services attached to the company’s network that they need to reach. Which VPN technology is most suitable to deliver a secure, fast, and reliable connection to theses employees? In this thesis examines we are taking a closer look at different VPN solutions. We describe different VPN-protocols like L2TP, IPSec and PPTP. How to authenticate users in a secure and flexible way and also methods used to make the VPN-connection secure. Lastly we will show the solution we have implemented at the company Confidence, for whom we made the solution. The difficulties in using existing products with the company’s infrastructure are described. Suggestions are offered for future work to address these problems.

Kuwait is planning for huge infrastructure and development projects through long term strategies and visions from 2007 until 2035 to overcome the needs for the welfare housing and to move the country to be the region’s top commercial and financial hub. These goals wouldn’t be achieved without having a strong partner (private sector) to drive the economy by participating in construction mega projects. Public-private partnership (PPP) is the framework which engages both parties to successfully achieve long term plans to deliver what the country and citizens need. To attract the private sector to participate and provide the services needed with the expected high qualities and techniques, the public sector needs to improve the environment to facilitate PPP implementation. This research investigates the existence of critical success factors of PPP project in construction sector of Kuwait: Effective procurement, Project implementability, Available financial market, Government guarantee and Favorable economic conditions and give recommendations to focus on improving them to achieve successful PPP projects.

Education in South Africa is a key concern because the South African education system is underperforming compared to many other developing countries despite the large capital investment made by the South African government and its private sector. South African children are routinely underachieving and rate not only among the worst in the world, but often among the worst in the Southern African region and in Africa as a whole. Therefore, the aim of this study was to explore whether Public-Private Partnership (PPP) is a suitable model for improving the quality of education in South African rural communities.The objective of the study was answered in a two-phase approach. The first phase developed an understanding of the challenges that prevents the delivery of quality education in South African rural communities with experts in education. The second phase determined the suitability of PPP to improve the quality of education in South African rural communities and the critical success factors for implementing PPP in education from interviews with PPP practitioners.The findings of the study revealed that PPP is a suitable model to improve the quality of education in South African communities and a PPP framework was proposed by the researcher that indicates the benefits of implementing PPP, the critical success factors of PPP and the barriers of PPP in education. The study also highlighted conditions that must be met to achieve quality education in South African rural communities through PPPs.The research concludes by making recommendations to both the government and the public sector in light of the findings of this research. Limitations for the study were highlighted and other variables to be researched that are important to further understanding of PPP as a model to improve the quality of education in South African rural communities were suggested. / Dissertation (MBA)--University of Pretoria, 2012. / Gordon Institute of Business Science (GIBS) / unrestricted

Strengthening health care systems in government meant cost containment and improved equity. Escalating costs and poorly constructed strategies are weakening the efficiency and effectiveness of service delivery in health care. This has a negative impact on value creation and internal processes as critical elements such as human capital, information and organisational capital are not aligned with strategies and roll-out plans for HIV/Aids interventions. This research study therefore questioned the extent to which these strategies have impacted on the roll-out plans for HIV/Aids interventions, and investigated if the utilisation of public-private partnerships (PPP) resulted in applying fiscal reponsible mechanisms in health care reforms (effectively, efficiently, economically and equitably (4Es)). Trends in the new public management (NPM) movement inspired a shift towards business-like reforms and saw PPP as a mechanism that improved efficiency and effectiveness in service delivery as it offered the promise to strengthen the capacity of government policy. The study aimed to put forward value-creating strategies and develop a best practice model that strengthened government’s policy capacity by providing efficient, effective, economical and quitable service in health care and thereby improving strategies that impact on the roll-out plans for HIV/Aids. This comparative study comprised four international case studies (developed and developing countries) which presented benchmarks against which the performance of the national case study was measured. A better understanding of the influence which different ideologies had on the architecture of international and global governance structures was gained as it highlighted and compared the key issues that influenced strategies for HIV/Aids intervention between the developed and developing countries. Results of the study indicated that there are conflicting views between government departments in how to achieve value-for-money outcomes and their application of risk allocation. The conflicting views widened the gap between public and private governance structures and relations. The focus of the PPP definition as applied in the national context of health care is not percieved as being health-specific or effective as it excludes some forms of interactions occurring in the health sector. PPP goals emphasised efficiency, affordability and value-for-money approaches, while health care goals emphasised the interest of the “patient” and public health. / Thesis (PhD (Public Affairs))--University of Pretoria, 2007. / School of Public Management and Administration (SPMA) / unrestricted

Local public agencies turn to public-private partnerships (PPPs) to allow greater participation by private firms in delivering public services. In the last 25 years, private organizations had been reluctant to form PPPs with local government agencies because of the complex procurement processes and the bureaucratic business environment. Guided by the decision theory and complex adaptive systems theory, the purpose of this multiple case study was to identify what information leaders within third-party administrators (TPAs) need regarding the contracting process in the formation of PPPs. The data collection process consisted of face-to-face interviews with 4 executive leaders of 3 Wisconsin state licensed TPAs and examination of contracts and plan service agreements (PSAs) between TPAs and local government agencies. Dada was analyzed using the Yin 5-step data analysis method and cross-case analysis. The results indicated that TPA leaders must understand collaborative leadership, key players, roles and responsibilities, and specialized services in the formation of a PPP; change and transfer of controlling interest, and understanding the strengths and weakness of contract provisions are complex business systems that influence the decision to form a PPP; ERISA and compliance with applicable federal and state laws are critical contract stipulations to consider in the formation of PPPs; that market assessment, health care reform, and transparency between private and public partners are critical in the formation of PPPs. The implications for social change include new insights for PPP leaders that may enhance the effectiveness of social services and save taxpayers' money.

Cette thèse se penche sur les contributions de la formation enseignante partiellement à distance et à l’aide du mobile, comment celles-ci évoluent et quels facteurs l’influencent. Les deux premiers chapitres discutent le contexte de recherche de cette thèse. Ils montrent le lien étroit entre l'évolution des politiques éducatives, les stratégies de recrutement des enseignants et la nécessité d'une formation à la fois réaliste et qualitative des enseignants. Après un rappel de la croissance exceptionnelle du secteur des infrastructures mobiles, la revue de littérature expose les résultats de recherches récentes de l’utilisation du mobile pour la formation des maitres à distance. Le contexte de la recherche montre qu'il y a un manque de recherche sur les contributions à moyen terme de la formation assistée par mobile et que cela est étroitement lié à l'approche ‘court-termiste’ des projets pilotes. C’est pour cela que quatre études (chapitres 5 à 7) cherchent à analyser les contributions dans une perspective à la fois multidimensionnelle et longitudinale. La première étude (chapitre 5) analyse d'un point de vue exploratoire les contributions rapportées et observées de la formation IFADEM chez les anciens participants. Il révèle entre autres que les contributions de soutien sont principalement reposent sur le mobile et sont intégrées dans la sphère professionnelle et privée. Ces usages durables sont motivés par une motivation intrinsèque et perdurent grâce à une forte expérience d'appropriation collective qui a servi de « coup d'envoi» aux nouvelles pratiques. Compte tenu de la domination des usages mobiles, la deuxième étude (chapitre 6) se concentre sur les communications mobiles. Elle confirme la pérennité des communications téléphoniques malgré la fin des stimuli organisationnels ou financiers externes, et montre également comment ces communications durables par téléphone reflètent l'appropriation permanente du mobile pour le travail et le privé. Ce chapitre permet en outre d'identifier les facteurs clés qui permettent ce processus d'appropriation en premier lieu. En plus de cette identification de ce que l'on peut appeler des « facteurs de risque et de réussite» pour des contributions mobiles de formation continue des enseignants, elle révèle également l'importance de la communication continue entre pairs parmi les anciens participants. Par la suite, la troisième étude (chapitre 7) analyse les structures et les processus de ces connexions mobiles prises en charge. Comme l'ont indiqué les répondants interrogés pour la première étude, la présence d'un réseau d'enseignants collaboratif stable pourrait être confirmée. Son analyse permet de qualifier les liens entre les anciens participants, qui sont à la fois de nature instrumentale et expressive. Les motivations multiples pour faire partie de ce réseau contribuent à sa durabilité et à son autonomie plus de deux ans après la fin de la formation, durabilité qui est renforcées par la présence de leaders qui assurent la circulation de l'information interne et externe. Globalement, il fournit une perspective supplémentaire sur l'importance et les résultats d'un processus d'appropriation collective. Enfin, la quatrième étude (chapitre 8) change de perspective, abordant la question des contributions à moyen terme et des facteurs pertinents pour la durabilité à travers l'organisation des parties prenantes, à savoir ceux qui financent, organisent, conçoivent et évaluent la formation mobile des enseignants. Cette étude indique non seulement que les acteurs se perçoivent comme faisant partie d'un système soumis à une pression politique considérable et exigent que leurs activités soient fortement limitées, ce qui conduit à une perspective à court terme sur les facteurs de succès. / This dissertation analyzes the contributions of mobile supported teacher training, how these evolve and which factors take influence on this evolution. The first two chapters expose the close link between the evolution of education policies, teacher recruitment strategies and the need for a both realistic and qualitative teacher training. After a recall of the exceptional growth of mobile infrastructure sector, the use of distance and notably mobile supported teacher training is discussed. The research context shows that there is lack of research on the medium-term contributions of mobile supported teacher training and provides strong indicators that this issue is closely related to the overall short-term approach of pilot projects. Therefore, four studies (chapter 5 to 7) seek to analyze contributions through a both multidimensional and longitudinal perspective. The first study (Chapter 5), analyzes from an exploratory perspective the reported and observed contributions of the IFADEM training among former participants. It reveals amongst others that the sustaining contributions are mostly mobile phone supported and well embedded in the professional and private sphere of former individuals. These sustainable usages are driven by intrinsic motivation, and sustain because of a strong collective appropriation experience that acted as ‘kick off’ phase for new practices. Given the domination of mobile usages, the second study (chapter 6) focuses on mobile communications, one of the reported key contributions of the IFADEM training. It confirms the sustainability of phone communications despite the end of external organizational or financial stimuli, and shows also how phone these sustainable communications reflect the ongoing appropriation of mobile for work and private matters. This chapter allows further to identify those key factors that allow for this appropriation process to happen in the first place. Besides this identification of what can be called ‘risk and success factors’ for sustainable mobile teacher training contributions, it reveals also the importance of ongoing peer to peer communication among former participants. Subsequently, the third study (Chapter 7) analyzes structures and processes of these mobile supported connections. As indicated by respondents interviewed for the first study, the presence of a stable, collaborative teacher network could be confirmed. Its analysis allows qualifying the ties among former participants, which are both of instrumental and expressive nature. Multiple motivations to be part of this network contribute to its sustainability and autonomy over two years after the end of the training, strengthened by the presence of leaders who ensure internal and external information flow. Overall, it provides an additional perspective on the importance and outcomes of a collective appropriation process. Finally, the fourth study (Chapter 8) shifts perspectives, approaching the question of medium-term contributions and pertaining factors for sustainability through the lens of organizing stakeholders, i.e. those who fund, organize, design and evaluate mobile teacher training. This study indicates not only that actors perceive themselves as part of a system with considerable political pressure and demands that constraint significantly their activities, leading to a short term perspective on success factors.It reveals also that projects partners are considered simultaneously as goal and obstacle. Their descriptions indicate an often difficult and sometimes patronizing relationship, which occupy a central place in projects preoccupations’. Actors depict also pilot projects as organizational and political instrument. The collision of a normative discourse of high moral value with a technical and organization oriented discourse is one of the striking results of this study.
