Studiens syfte var att få en fördjupad förståelse för hur högkänsliga personer upplever att personlighetsdraget påverkar olika relationer och sociala situationer i dagens sociala samhälle. Data samlades in genom semistrukturerade intervjuer med nio personer som definierar sig som högkänsliga. Informanternas svar analyserades sedan i en tematisk analys för att få fram en överblick över deras upplevelser. Resultatet indikerar att personlighetsdraget påverkar relationerna med andra på många olika sätt, bland annat genom högkänsligas förmåga att läsa av andra, deras djupa bearbetning och deras behov av att undvika överstimulering. Det framkom även att högkänsligas egenskaper inte alltid accepteras eller förstås av omgivningen. / The aim of this study was to get an immersed understanding of how highly sensitive people experience that the personality trait affects various relationships and social situations in today’s social society. Data were collected through semi structured interviews with nine people defining themselves as HSP. The answers from the informants were thereafter analyzed using thematic content analysis to get an overview of their experiences. The result indicates that the personality trait affects the relationships with others in various ways, for example by the ability of the highly sensitive to understand others, their deep processing and their need to avoid overstimulation. It also emerged that the characteristics of the highly sensitive people were not always accepted or understood by the surroundings.

Modern database systems have to process huge amounts of data and should provide results with low latency at the same time. To achieve this, data is nowadays typically hold completely in main memory, to benefit of its high bandwidth and low access latency that could never be reached with disks. Current in-memory databases are usually columnstores that exchange columns or vectors between operators and suffer from a high tuple reconstruction overhead. In this paper, we present the indexed table-at-a-time processing model that makes indexes the first-class citizen of the database system. The processing model comprises the concepts of intermediate indexed tables and cooperative operators, which make indexes the common data exchange format between plan operators. To keep the intermediate index materialization costs low, we employ optimized prefix trees that offer a balanced read/write performance. The indexed tableat-a-time processing model allows the efficient construction of composed operators like the multi-way-select-join-group. Such operators speed up the processing of complex OLAP queries so that our approach outperforms state-of-the-art in-memory databases.

AIM The objective of this study is to determine factors that may contribute to hospital admissions in a cohort of medically insured South African patients in the era of HAART. METHODS This was a retrospective cohort of all HIV-positive adult and paediatric patients enrolled on a medical aid disease management programme in South Africa over a period of three years. Patient-specific demographic and clinical information were obtained from the medical aid records. Survival analysis was used to analyse time to first admission looking at admissions occurring after enrolment to the programme, during the study period of between 01 January 2006 and 31 December 2008. Only the right censored cases were included in the analyses. Descriptive analyses were conducted on the key prognostic factors. Variables that were significant in the univariate were considered in the multivariate Cox proportional hazards model. RESULTS A total of 8440 patients were included in the analysis. Half of these patients had at least one admission during the observation periods with 43.28% having had 2 or more admissions. The average admission rate was 2 admissions per patient over the 36 month observation period. Young children, adolescents and the very old (> 60 years) were significantly more likely to be admitted than the middle age groups, HR = 1.30 [95%CI 1.21 -1.40] p<0.01, 1.24 [95%CI 1.10 – 1.41] and 1.13 [95% CI 1.10 – 1.27] p<0.01 respectively. Low CD4 cell counts of < 200 cells/ µL were significantly associated with a higher likelihood of hospitalizations with hazard ratios even greater for CD4 cell counts of less than 100 cells/ µL, HR= 1.34 [95%CI 1.29 – 1.39], p<0.01. Cases were more likely to be admitted by a clinical haematologist or gynaecologist than by other specialist categories.HR =1.58 [95%CI 1.29 –1.94] and 1.17[95%CI 1.08 – 1.27] respectively with p<0.01. CONCLUSION Factors that are associated with hospital admissions in this private sector, medically insured population are a younger and older age, low CD4 cell counts and admission by a clinical haematologist and gynaecologist. These results suggest that disease management strategies should be intensified for the younger and older age groups. All HIV-positive patients should be closely monitored for CD4 deterioration so that treatment is initiated timeously. Routine haematological investigations should be recommended for all HIV-positive patients in order to pick up and treat haematological conditions before they result in a hospital admission. Evidence based guidelines, outlining the place of caesarian section deliveries in the HIV population, should be developed for use by gynaecologists specifically in the private sector.

Peridotites occuring in orogenic massifs provide important insights into geochemical processes of the Earth's upper mantle by providing direct evidence of mantle evolution throughout Earth history. It has been previously demostrated (e.g. Medaris et al., 1990, 2005) that the uppermost tectonic unit of the Bohemian Massif - the Gföhl Nappe hosts a variety of peridotites that originated from different sources, including subcontinental lithosphere, suboceanic asthenosphere, and possible ultramafic layered intrusive complex. The Czech peridotites of the Gföhl Nappe has been divided into three groups, defined by Medaris et al. (1999), according to their chemical compositions, identity and relations of the aluminous phases, ortopyroxen compositions and estimated P-T conditions. According to Medaris et al. (2005) "Type I" peridotites - represented by Mohelno and Biskoupky bodies - equilibrated in low P-T regime (recording the highest equilibration temperatures - up to 1335 ⁰C at 29 kbar - among the Gföhl peridotites) consist of spinel peridotite with garnet appearing only at its margins. Peridotites are enclosed in granulites that have been extensively recrystallized mostly at amphibolite-facies conditions. Many studies have been done on this locality and a wide range of mineralogy and P-T histories has...

This thesis entitled "Impact of Collective Action in Controlling Migratory Flows: Understanding Migratory Flows within the European Union" analyses the various factors which impact upon migration decision-making and remigration potential among Slovak migrants who entered the Czech Republic after the country acceded to the European Union. The thesis utilizes a meta- theoretical approach which provides wide latitude for the inclusion of theoretical approaches which transcend disciplinary boundaries. Through a discussion of various policy approaches the work demonstrates that attempts to limit flows via legislative changes or the implementation of European Union directives has had little impact on aggregate flows in the specific case of the Czech Republic. Data from a survey conducted by the author is analysed and discussed from various perspectives in the form of a descriptive case study. The case study determines that employment, personal choice and family reunification are significant rationales for mobility related decision making and that long term settlement among this particular group is likely to occur.

The aim of this dissertation is to contribute to a better understanding of highly skilled (re-)migrants as labour force in multinational enterprises (MNEs) and their role in cross-border knowledge transfers. To achieve this goal, an actor-centred research perspective will be adopted, which allows for a detailed examination of both individual employees and strategies of MNEs. The basic conceptual understanding of this work is based on the relational economic-geographical approach (Bathelt and Glückler 2002), on the basis of which research strands and theories of economic geography, international business studies and migration studies were intertwined. The empirical study is based on the example of highly skilled (re-)migrants of Turkish origin who work for German companies in Turkey. The study focuses on (re-)migrants of Turkish origin who have obtained a university degree in Germany. The study follows a qualitative research design based on 95 semi-structured interviews. The interviews were conducted with highly skilled (re-)migrants as well as with company internal and external experts. In addition to the semi-structured interviews, a netnographic collection of data from an online group for (re-)migrants of Turkish origin is conducted. The findings of this thesis show that highly skilled (re-)migrants of Turkish origin who have obtained a university degree in Germany are not to be regarded as a homogeneous group but rather have diverse educational and career paths. In addition to their high level of education, they have excellent language skills (mostly Turkish, German and English). They are also mostly familiar with the cultural and institutional contexts in Germany and Turkey, which, according to Hess (2004), is referred to as dual societal embeddedness. Highly skilled (re-)migrants of Turkish origin are important transnational experts for German companies in Turkey. They are particularly in demand if the companies 1) have a strong orientation towards German-speaking markets and/or 2) are dependent on close cooperation with German company locations. In these companies, highly skilled (re-)migrants of Turkish origin are strategically deployed in central areas of the company, where they often work at interfaces due to their transnational abilities, which require close contact with local employees and employees of German company locations. The empirical results also show that highly skilled (re-)migrants of Turkish origin make a significant contribution to the cross-border knowledge transfers in German companies in Turkey. Highly skilled (re-)migrants of Turkish origin are primarily involved in intra-organisational knowledge transfer with employees of German company locations. Due to their dual societal embeddedness and their profound language skills, highly skilled (re-)migrants are able to bridge the institutional distance between German and Turkish company locations. This is particularly important for the transfer of implicit knowledge, which is based on know-how and experience and is therefore difficult to transfer between different cultural and institutional contexts. In concrete terms, highly skilled (re-)migrants of Turkish origin facilitate cross-border knowledge transfers through three main activities: building knowledge networks, mediating frictions, transmitting knowledge. The results of a case study also show that highly skilled (re-)migrants can play a decisive role in the offshoring of knowledge intensive business services within global production networks Thereby, highly skilled (re-)migrants help to mitigate resistance and facilitate the dis- and re-embedding of knowledge within the offshoring process. Overall, this thesis contributes to the geographical (re-)migration research, to research on the geography of knowledge in MNEs, and to global production network research.

The purpose of this study was to explore and describe the determinant factors affecting adherence to antiretroviral therapy among HIV infected patients in Addis Ababa, Ethiopia. A cross-sectional study design was used and data were collected by interviewing 290 study participants from two health facilities using structured questionnaire. The research finding revealed 80.0% of the study participants had optimal combined adherence to dose, schedule and dietary instructions in the past three days. And, the non adherence rate was 20.0%. In multivariate analysis only WHO clinical stage, change of ARV medication, knowledge about HIV disease and ART, and use of reminders were found to be independently associated with adherence to antiretroviral therapy. The most common reasons for missing HIV medications in the past one month were forgetfulness (35.1%), being busy with other things (17.5%), and running out of pills (10.5%). Adherence improving interventions should be emphasized to address multi-faceted problems. This study recommends setting of convenient appointment schedule, disclosure of one's HIV status, maintaining confidentiality of patient-related information, enhancing patient-provider relationship, use of reminders including SMS text messages, and engagement of PLHIV in adherence improving interventions through peer support, and providing regular health education to the PLHIV to improve adherence of patients to ART / Health Studies / M.A. (Public Health)

As the presence of digital game-based learning increases in United States classrooms, understanding their impact on achievement is critical. Digital games for learning offer many potential benefits, including reducing the number of students trapped in a remediation cycle, a contributor to college dropout. Despite the recognized potential of game-based learning, few researchers have explored the relationships between specific patterns of behaviors and types of digital game-based learning environments. The underlying theory for this study was patterns of gamer behaviors may predict in-game behaviors. Archival, third-party data regarding The Lost Function - Episode 1: Sum of the Forgotten Minds by Advanced Training & Learning Technology, LLC was used in this study. Using 4 case groups at the high school and college levels (n=114), self-reported levels of the 3 patterns of gamer behaviors, gender, and age-band were analyzed using multiple regression to determine relationships to time-on-task in a game-based highly interactive virtual environment, designed for mathematics remediation. While the results were inconclusive, this study supported the existing literature regarding gender differences and the lack of mutual exclusivity in behavior typing. Recommendations include additional research in how the statements used in the 3-factor model may be adjusted to allow for a broader population of game players. The social change implication is that further understanding of the relationship between learner traits and digital learning environment may assist educators that employ digital game-based learning a way to better align learners to the most appropriate digital learning environment, thereby increases their chances at success.

I investigated why math capable students are not entering science, technology, engineering, and math (STEM) careers. To research the problem, I explored how highly effective elementary math teachers (HEMT) create student interest in mathematics using the self- efficacy (SE) theory and information and communication technology (ICT). The purpose of the study was to discover if teacher training and instructional strategies can influence student interest in mathematics to improve STEM career entry. The theoretical framework adopted for this study was the SE theory, and the 4-phase model of interest development was the conceptual framework. Participants in this multi-case qualitative study included 5 HEMT who work in a southern ICT-based urban school. The data gathered were individual teacher observations, interviews, and discussions about student artifacts, which were then analyzed for themes and patterns using NVivo software. The results indicated that the teacher participants use vertical curriculum experiences to improve student SE in 4th and 5th-grade students to fill-in curriculum gaps. Also, problem-solving math equations based on real-world simulations are used to stimulate and sustain a perceived student interest in mathematics. Additionally, ICT was used to augment math lessons and to personalize learning. Society will benefit from this information when educational stakeholders implement instructional strategies that improve student interest through the use of real life scenarios. Real-world math applications can influence elementary student interest in taking higher levels of math education that lead to STEM careers.

Since changes to the reading/language arts State Subject Area Test (SSAT) in late 2010, elementary education teacher candidates at a teacher training college in the Southern United States have experienced declining scores resulting in test failure and delaying student teaching and graduation. The purpose of this case study was to identify factors that students and faculty perceived as most beneficial in preparing students to pass the SSAT. Constructivism served as the conceptual framework for this study addressing the effects of collaboration, hands-on learning, and application of knowledge. Purposeful sampling was used to recruit 6 elementary education students who had taken the SSAT and 4 full-time reading and language arts faculty members who participated in semistructured interviews. Analysis of coded data indicated themes of preference for experiential learning, intensive strategy instruction, and a review of tested content. Based on study findings, a 3-day professional development training was created to provide students a review of tested subject matter through embedded strategy instruction and opportunities for hands-on application of learning. Implications for positive social change include preparing students to pass the SSAT in fewer attempts so they can graduate on schedule and begin their careers. Local communities may benefit from the addition of highly qualified teachers ready to enter elementary classrooms across the state during a critical teacher shortage.
