Accountability in community colleges, like all institutions of higher education, is a movement that has grown over the past several years. Consequently, colleges are generating a great deal of assessment data, both locally developed and nationally benchmarked. One national survey is the Community College Survey of Student Engagement (CCSSE). CCSSE is an appropriate focus for this study because many community colleges are concerned about the lack of comparative data that would enable them to make more comprehensive evaluations of their programs. This is a case study of a college in Wyoming and its use of the CCSSE data after the college received the results of the survey. A Wyoming college is the focus because it performed adequately on the CCSSE measures and was not currently under any economic pressures that may have affected colleges in other parts of the country during the time frame of the study. / text

The wireless medium is lossy due to many reasons, such as signal attenuation, multi-path propagation, and collisions. Wireless losses degrade network throughput, reliability, and latency. The goal of this dissertation is to combat wireless losses by developing effective techniques and protocols across different network layers. First, a novel opportunistic routing protocol is developed to overcome wireless losses at the network layer. Opportunistic routing protocols exploit receiver diversity to route traffic in the face of loss. A distinctive feature of the protocol is the performance derived from its optimization can be achieved in real IEEE 802.11 networks. At its heart lies a simple yet realistic model of the network that captures wireless interference, losses, traffic, and MAC-induced dependencies. Then a model-driven optimization algorithm is designed to accurately optimize the end-to-end performance, and techniques are developed to map the resulting optimization solutions to practical routing configurations. Its effectiveness is demonstrated using simulation and testbed experiments. Second, an efficient retransmission scheme (ER) is developed at the link layer for wireless networks. Instead of retransmitting lost packets in their original forms, ER codes packets lost at different destinations and uses a single retransmission to potentially recover multiple packet losses. A simple and practical protocol is developed to realize the idea, and it is evaluated using simulation and testbed experiments to demonstrate its effectiveness. Third, detailed measurement traces are collected to understand wireless losses in dynamic and mobile environments. Existing wireless drivers are modified to enable the logging and analysis of network activity under varying end-host configurations. The results indicate that mobile clients can suffer from consecutive packet losses, or burst errors. The burst errors are then analyzed in more detail to gain further insights into the problem. With these insights, recommendations for future research directions to mitigate loss in mobile environments are presented. / text

This qualitative field study investigated cross-site knowledge sharing in a small sample of multinational corporations in three different MNC business contexts (global, multidomestic, transnational). The results disclose heterogeneous "worlds" of MNC knowledge sharing, ultimately raising the question as to whether the whole concept of MNC knowledge sharing covers a sufficiently unitary phenomenon to be meaningful. We derive a non-exhaustive typology of MNC knowledge-sharing practices: self-organizing knowledge sharing, technocratic knowledge sharing, and best practice knowledge sharing. Despite its limitations, this typology helps to elucidate a number of issues, including the latent conflict between two disparate theories of MNC knowledge sharing, namely "sender-receiver" and "social learning" theories (Noorderhaven & Harzing, 2009). More generally, we develop the term "knowledge contextualization" to highlight the way that firm-specific organizational features pre-define which knowledge is considered to be of special relevance for intra-organizational sharing.

Bakgrund Ordet kundägt används av både ömsesidiga och kooperativa bolag men vad är ett kundägt bolag för något och vad gör ett kundägt bolag speciellt? I förhållande till sina marknadsandelar är kundägda bolag understuderade vilket motiverar en explorativ studie för att öka kunskapen kring den här typen av bolag. Syfte Genom att göra en explorativ kvalitativ fallstudie i ett kundägt företag vill vi driva fram akademiska undersökningsområden för att främja den företagsekonomiska forskningen i området. Metod Studien gjordes genom en explorativ kvalitativ fallstudie på Länsförsäkringar Östgöta på grund av att det är ett framgångsrikt kundägt bolag. Fyra personer från ledningsgruppen på Länsförsäkringar Östgöta och en person från dotterbolaget Länsförsäkringar AB intervjuades. Parallellt så inhämtades information även från deltagande observationer och dokument för att förstärka empirin som genererades vid intervjutillfällena. Slutsats Studien bidrar med att visa att kundägda bolag fortfarande spelar en viktig roll på marknaden och visar på ett antal områden som bör studeras närmare. En av de främsta punkterna är den lokala aspekten som verkar samverka med det kundägda för att skapa en organisation med hög trovärdighet bland kunderna. Hur konceptet med ett kundägt lokalt bolag påverkas av digitaliseringen är en annan punkt som bör väcka ett intresse bland forskarna att studera vidare. / Background The word customer-owned is used by both mutuals and cooperatives but what is a customer-owned company and what makes it special? Customer-owned companies are in relation to their market shares less studied which motivates an explorative study to increase the knowledge about this type of companies. Aim We want to develop academic research areas to advance the theory in the field of business by doing an explorative qualitative case-study in a customer-owned company. Methodology The study was made by an explorative qualitative case-study on Länsförsäkringar Östgöta as it is a successful customer-owned company. Four people from the Länsförsäkringar Östgöta management team and one person from the subsidiary Länsförsäkringar AB was interviewed. Data was gathered parallel to the interviews by participatory observations and documents to enhance the empiricism. Conclusion The study contributes by showing that customer-owned companies still plays an important role in the market and the study also shows areas were future research should be conducted. One of the main conclusions is that it seems like the local aspect have synergies with the customer-owned to create a company that have a high level of trustworthiness. How the concept with a local and customer-owned company will fare in a more digitalized world is another area that should have a high interest among researchers.

Many of the recent armed conflicts have taken place in cities of the Developing World. In the resulting emergency situations, water supply and sanitation are among the most essential services to restore. They form part of the urban services available to the city dwellers that are commonly managed by local water sector institutions. This is, in principle, acknowledged by aid agencies but partnerships between them and water sector institutions do not always happen because of concerns such as: independence vis-a-vis the local government; possible corruption arid inefficiency problems; and political obstacles. Moreover, agencies prefer short-term structural rehabilitation to long-term institutional development, for which they do not always feel sufficiently qualified and experienced. This study tackles the problem by determining how these partnerships influence the performance of aid operations, in particular in terms of efficiency I effectiveness in the case of emergency response and of sustainability and coverage in the case of rehabilitation. It is based on a number of case studies selected in: Kabul (Afghanistan); Jaffna (Sri Lanka); Monrovia (Liberia); Beni (Democratic Republic of Congo); Port-au Prince and Port-de-Paix (Haiti), and Grozny (Chechnya in the Russian Federation). For emergency operations, findings show that partnerships tend to take place when the type or level of technology involved and/or security conditions do not allow the aid agency to work independently from water utilities. Partnerships do not necessarily influence efficiency I effectiveness in the short term but are beneficial because they prepare for rehabilitation. In terms of rehabilitation, findings suggest that current practice maintains a separation between large-scale rehabilitation projects and community-based projects focusing on specific neighbourhoods. This has a detrimental effect on sustainability and fails to address the needs of the most vulnerable populations. The study recommends a more coordinated approach that involves a reform of funding patterns, in order to reconcile sustainability and universal service.

The purpose of this project is to describe one teacher's non-traditional approach to teaching Mathematics A in municipal adult education. A case study has been carried out over the course of one semester of teaching, involving classroom observations, formal and informal interviews with the teacher and students, surveys and the collection of teaching materials. Each of the aspects of the teaching approach are described and discussed including “book lessons,” “practical lessons,” examinations and group work. The teacher's and students' comments on the teaching approach are recorded along with my comments. The following two questions are also addressed: What is required of the teacher for the implementation of a non-traditional way of working with Mathematics in adult education? and What is the significance of groups in a non-traditional mathematics environment? The non-traditional teaching approach described in this project was able to be linked to a social-constructivist approach to viewing mathematics teaching and learning. With the help of this project, it can be seen that non-traditional approaches to teaching Mathematics can be implemented in the classroom, even in municipal adult education classrooms.

This doctoral thesis consists of a thesis for a Licentiate degree (Kristoffersson, 2002. Föräldrainflytande i grundskolan. En studie av nio lokala styrelser med föräldramajoritet i grundskolan. [Parents involvement in compulsory school. A study of nine local boards with parents in majority in compulsory school]) and two articles (Kristoffersson, 2005. Parental involvement: Parents´ new role in Swedish schools; and Kristoffersson, 2007. The paradox of parental influence in Danish schools. A Swedish perspective). In this thesis my interest is particularly governance, management, communication and partnership. The research aimed comprehensively to describe the school boards and discuss the education policy behind the implementation of the boards. An additional aim were to see whose interests favoured in local school boards. I also wanted to study how comparative research in this case can be relevant to Swedish studies of local school boards. I used the frame factor theory, which aids the exploration of the correspondence relations between factors that affect local school boards. Governance and partnership are key concepts applied to the analysis of data. Critical analysis and discussions of these boards from a hermeneutic sign are included, which meant that I tried to understand the boards in their context. I used a case study method. Data were gathered through interviews, observations and analysis of documents (e.g., school board minutes). The results signify that different interests are not adequately balanced on the boards. Communication between the board and the parents not on the board was not satisfactory in many cases and such parents felt excluded from the board’s activity. The principal’s collaboration with the board’s chairperson was an important influence on the board. Evaluation, support and feedback of the board’s activity from the local school authority in the municipality were often neglected. The implementation of the boards related to the transferred welfare policy to more market-oriented political governance. The political governing of the school changed, and was influenced by neo-liberal trends where partnership had become the new prestige word. Parents are today seen as individual consumers in a market, whereas as board members they should make decisions that include all parents. Instead of increased parental influence in the schools, the effect of boards could be increased differences between pupils and between parents. This arose because parents are not a homogenous group. Social, cultural and economic conditions have an influence on parents’ activities. The state implementation of local school boards in Sweden and in many countries is, therefore, complex. This can be seen through the weak interest in the creation of boards, which also can be linked to the top-down character of the reform. This study is an example where global, national and local factors interact.

Within the field of microfinance, there has been an ongoing debate about whether microfinance institutions should be commercialized. One side argues that a business that very much can earn profits at the same time as it helps the poor, is not justified to receive charity, but should be run with the risks and benefits of any other profit-seeking business. The other side argues that the outreach to the ones who most need microfinance, is severely hampered if firms are profit-seeking; arguing that they only target the individuals who allow them to make profits.   This study is a case study based on India, one of the world’s largest nations, and home to millions of people living below the poverty line[1]. Microfinance is widespread in India, and with one of the researchers speaking Hindi, India became our choice of case study. A grounded theory methodology is applied in order for us to learn as much as possible about the context of microfinance in India. Within the context, we look for the mission and the impact of the various institutions. Analysis is done through the constant comparison method; with comparisons within and between different organizations. Each organization is individually analyzed to find recurring themes, always being open to the emergence of new themes. Then, the organizations are compared with others of the same legal form, and finally with all other forms of organizations.   Several different kinds of institutions are identified, working directly or indirectly with providing small loans to low-income individuals. These institutions include banks, local area banks, section 25 companies, NGOs, and cooperative societies. Each one of the institutions has, by law, different areas of restriction and the study finds that the missions of the various organizations can be linked to their legal form; the mission indicating which form they currently operate under or which legal form they are striving to achieve. The major difference between the various legal forms is their methods of accumulating finances, and how they manage their revenue. Although banks actually earn profits, they have not yet been fully commercialized, as they are restricted from attracting mainstream international capital.   The conclusions indicate that in India, microfinance has not reached the point where it has been fully commercialized, but rather the passion for their work and visions of the founders very much guide the work of the various organizations. This can be seen in the missions that guide the organizations and the services provided to fulfill the mission. Commercialization is however, far from a non-issue. If legislation regarding IPOs is changed, the level of commercialization and competitive scene for microfinance in India could change dramatically. [1] Can be measured in different ways, but used here symbolically, indicating a very low amount; discussed in more detail in the paper.

China’s status as the world’s top destination for foreign direct investment and the largest trading nation is likely to attract more international firms seeking market entrance, and increase the speed of expansion by those already present in the market. Its progress in reaching this point has been accompanied by significant changes in laws and regulations. This study sets out to understand the events of foreign market entry to emerging markets experiencing recurring changes in laws and regulations, and asks the research question: How may institutional change in the host market influence the market entry behaviour of the firm over time? Based on retrospective longitudinal case studies of DeLaval, Elekta and Höganäs from 1980 to 2010, the findings show that institutional change taking place in the host market plays a signal role that enables firms to recognise the availability and accessibility of market opportunity. Firms also make market commitment accordingly to capture the market opportunity recognised. Additionally, institutional change comes in different forms (transitional change and turbulent change), and plays out differently in various industries and at various points in time. They also have varying influences on market opportunity in terms of the source through which it is recognised (structural opportunity and relational opportunity), and the direction in which market commitment is made (commitment toward the host market, relationships, and organisational integration). Furthermore, depending on the point in time, the relations among institutional change, market opportunity, and market commitment may change. While a consistent level of institutional change encourages firms to recognise structural opportunity, the escalation of institutional change over time seems to influence firms to form stronger relationship commitment with local actors and leads to stronger recognition of relational opportunity. This study’s findings imply that recurring institutional changes in emerging markets have an overarching impact on foreign market entry of the firm, and needs to be understood from a long-term perspective. Foreign firms that have acquired experience in emerging markets over time face less of a threat from ongoing institutional changes. Actively engaging in the host market and remaining alert to information from various sources will enable firms to recognise market opportunity in emerging markets.

The objective with this research was to establish the correlation between problem solving and the teaching and learning of mathematics in grade 4. The results of the Third International Mathematics and Science Study (TIMSS) showed that South Africa is behind other countries in terms of the teaching and learning of mathematics, especially with regard to problem solving. Because problem solving is an integral part of the teaching and learning of mathematics, a literature study was conducted (1) to investigate the learning of school mathematics and (2) to describe the manner in which problem solving can take place in the classroom. The learning of school mathematics was studied by focusing on different approaches to the learning of mathematics. The constructionist approach to learning was identified as the appropriate approach towards learning, which correlates with outcomes-based education (OBE) and with the approach currently taught in South African schools. Factors which contribute towards the meaningful learning of school mathematics, namely mathematical knowledge and skills, meta-cognition, learning strategies and tasks and assignments in mathematics, have been discussed. The role of problem solving in the learning of mathematics was studied by means of a possible problem-solving model which may be developed together with the learners. The teaching of problem solving was investigated by referring to the planning of a problem-based lesson and attention was paid to the learning content of the lesson and the planning of the teaching-learning activities. Together with the learners a problem-solving model was developed for the teaching of problem solving. The implementation of the teaching of problem solving was described with reference to the use of big-group presentations as well as problem solving in small groups. Attention was also paid to problem solving, and the use of different assessment techniques was discussed. The empirical investigation was done by means of a case study, and the focus was firstly on the influence of problem solving on the learning of mathematics, and secondly on the manner in which problem solving may be taught. Information was collected during the qualitative investigation by using a questionnaire which was completed by the learners, as well as an interview and observation schedule. The class work, homework and group work books of the learners were studied and transcribed. Video recordings were made of the learners' participation in the big group, small groups and written work, and the transcribed information was used to make deductions about the teaching of problem solving to the learners. From the empirical investigation it became clear that there is a correlation between problem solving and the teaching and learning of mathematics. Problem solving may be taught to learners by means of a problem-solving model, although this does not necessarily result in successful problem solving by all learners. While learners are solving problems, they are also learning mathematical concepts and acquiring and applying mathematical skills. / Thesis (M.Ed.)--North-West University, Potchefstroom Campus, 2005.
