The research investigates the Centro Velico Caprera (CVC), a sailing school located in the Mediterrean Sea, whose purpose is to replicate the lifestyle of a ship on land. This ambition creates an isolated environment in which the frequenters are completely immersed and the life is heavily controlled through different spatial and temporal means. The people who attend the school and become part of its community refer to its characteristics and to the collective essence they experience as 'the Spirit of Caprera'. Using an ethnographic approach and in particular participant observation as a primary source of data, and formal semi-structured interviews, the research investigated the internal dynamics of the school and the nature of the 'spirit' by looking at the setting from the insiders' point of view. The investigation aspired to gain a better understanding of the setting as a sailing community and of the relationships that are created that appear to make this environment unique. The research used sociological concepts as 'benchmarks', such as total institution, status and roles, routine and rituals, subculture and power, to guide the data collection and the analysis. Moreover, it made use of key thinkers such as Goffman and Foucault. The analysis has revealed that in the Centro Velico Caprera the 'spirit' can be considered as the consequence and result of more specific dynamics. In particular, the school's organisational and institutional structure, the time management, the role and functioning of authority and finally the rules and norms that derive from the idea of being part of a unique crew. The research engaged also in the analysis of social class and gender discrimination that characterise the school. The study of this school contributes to the study of sport and in particular sailing, which has often been ignored, by adding a new perspective and analysis to its study. The main contributions surround the comparison with other similar sailing subcultures and realities, such as ocean cruising, the development of the concept of the sport panopticon related to authority and its functioning, the notion of spirit, its meaning and significance, and the particular structure of the institution with its consequence for the frequenters. Moreover, the study also aimed to contribute to the narrower debates surrounding the 'benchmark' concepts, their use and their understanding in social theory and for sport studies.

The aim of this study was to identify how Information and Communication Technology (ICT) affects business processes and service delivery within hotels and how ICT interacts with strategic issues confronting hotel managers. The areas of exploration were: 1) the business context of ICT; 2) the main role of ICT in day to day business; 3) ICT's impact on service delivery to hotel guests; and 4) the role of ICT in the future.As the study was exploring the General Managers' (GMs) perceptions, interviewing was selected as the most appropriate data gathering method. The sample covered a range of Auckland hotels which differed according to location, size and quality. Semi-structured interviews were used to facilitate the comparison of data between interviewees. Common themes and concepts were identified which were compared to the demographic characteristics of the hotels as well as previous research detailed in the literature.The contextual issues identified were staff availability and retention, competition (particularly price wars resulting from discounting), and location and infrastructure issues. Only half the GMs interviewed identified benefits from ICT in the day to day operation of their business. All of them described challenges or disadvantages posed by ICT. The impact on service delivery to guests was viewed more positively but there were still misgivings about the potential barriers which ICT created. There was a strong view that staff were of overwhelming importance to service delivery. Finally, envisioning the future, ICT was perceived as having the ability to make a strong contribution to business development but this ability would be constrained by staffing problems. Analyses of the findings suggest that ICT has a dual role of gathering management data and providing guest services, and GMs appear unaware of how this dual role contributes to the challenges posed by ICT. Similarly, there was limited awareness of the interaction between human agents in a business, the organisational structures, and ICT.The business implications of these findings suggest that GMs would benefit from being aware of the roles of ICT and addressing the needs of staff for a clearer understanding of how their role, and the ICT that supports it, fits into their broader operation of the business.This study is the one of first to examine the impact of ICT in New Zealand hotels, and, in particular, how this interacts with the broader social issues, and offers insights into the areas of potential conflict and ways to manage the impacts of ICT in hotels.

Recent years have seen a surge in the popularity of XML, a markup language for representing semi-structured data. Some of this popularity can be attributed to the success that the semi-structured data model has had in environments where the relational data model has been insufficiently expressive. Concomitant with XMLs growing popularity, the world of database research has seen the rebirth of interest in tree-structured, hierarchical database systems. This thesis analyzes several problems that arise when constructing XML data management systems, particularly in the case where such systems must handle dynamic content. In the first chapter, we consider the problem of incremental schema validation, which arises in almost any XML database system. We build upon previous work by finding several classes of schemas for which very efficient algorithms exist. We also develop an algorithm that works for any schema, and prove that it is optimal. In the second chapter, we turn to the problem of improving query evaluation times on extremely large database systems. In particular, we boost the performance of the structural and twig joins, fundamental XML query evaluation techniques, through the use of an adaptive index. This index tunes itself to the query workload, providing a 20-80% boost in speed for these join operators. The adaptive nature of the index also allows updates to the database to be easily tracked. While accurate selectivity estimation is a critical problem in any database system due to its importance in choosing optimal query plans, there has been very little work on selectivity estimation in the presence of updates. We ask whether it is possible to design a structure for selectivity in XML databases that is updateable, and can return results with theoretically sound error guarantees. Through a combination of lower and upper bounds, we give strong evidence suggesting that this is unlikely in practice. Motivated by these results, we then develop a heuristic selectivity estimation structure for XML databases. This structure is the first such synopsis that can handle all aspects of core XPath, and is also updateable. Our experimental results demonstrate the efficacy of the approach.

<p>The number of domains and tasks where information extraction tools can be used needs to be increased. One way to reach this goal is to construct user-driven information extraction systems where novice users are able to adapt them to new domains and tasks. To accomplish this goal, the systems need to become more intelligent and able to learn to extract information without need of expert skills or time-consuming work from the user.</p><p>The type of information extraction system that is in focus for this thesis is semistructural information extraction. The term semi-structural refers to documents that not only contain natural language text but also additional structural information. The typical application is information extraction from World Wide Web hypertext documents. By making effective use of not only the link structure but also the structural information within each such document, user-driven extraction systems with high performance can be built.</p><p>The extraction process contains several steps where different types of techniques are used. Examples of such types of techniques are those that take advantage of structural, pure syntactic, linguistic, and semantic information. The first step that is in focus for this thesis is the navigation step that takes advantage of the structural information. It is only one part of a complete extraction system, but it is an important part. The use of reinforcement learning algorithms for the navigation step can make the adaptation of the system to new tasks and domains more user-driven. The advantage of using reinforcement learning techniques is that the extraction agent can efficiently learn from its own experience without need for intensive user interactions.</p><p>An agent-oriented system was designed to evaluate the approach suggested in this thesis. Initial experiments showed that the training of the navigation step and the approach of the system was promising. However, additional components need to be included in the system before it becomes a fully-fledged user-driven system.</p> / Report code: LiU-Tek-Lic-2002:73.

In the 21st century, the mobility of world population has posed greater challenges to healthcare practitioners, since they are facing an increasingly diverse patient population from all over the world. At the same time, patients also find it difficult to access and utilize quality health care services in a culturally diverse context. This study examines the role of culture in Chinese international students’ health-seeking behaviours in Canada. The study explores any barriers/perceived barriers that Chinese international students may confront when accessing health care which can prevent them from obtaining quality health care services in Canada. To this end, an intercultural health communication model was employed as a theoretical framework, and semi-structured interviews were used as a data collection tool. While contributing to existing literature on health communication and culture, this study also hopes to contribute to providing Canadian universities and institutions important information regarding Chinese international students’ access to and utilization of health care services with the hope of enhancing the quality of ethnic health care and promoting better health outcomes.

Recent research has proposed a new stage in human development, termed emerging adulthood by Jeffrey Arnett, which is characterized by a prolonged journey to adult roles and responsibilities. This thesis explores the experience of Chinese emerging adults, university students aged 20-25 years using Erikson’s and Levinson’s developmental theories as a theoretical framework. These authors proposed that three major developmental tasks are necessary for the transition to adulthood: separating from family of origin, forming an adult identity and finding the place for the self in the larger society. Qualitative interviews were conducted virtually with 12 Chinese university students to understand their perceptions and lived experience. Qualitative thematic analysis was used to analyze the interview transcripts. The results suggest Chinese emerging adults (a) have a low level of separation from parents; (b) have not formed a clear sense of identity and have not achieved a self-definition in adulthood; and (c) have not made initial commitments to love and work. It is speculated that the Chinese sociocultural context may further postpone its young adults’ independence and autonomy, and this prolonged transition to adulthood is both positive and problematic to Chinese young adults. This study lends support to Arnett’s emerging adulthood theory through its exploration of emerging adulthood in China, where, to date, little research has been done on this subject. It provides rich descriptions of the experience of Chinese emerging adults’ lives and enhances understandings of the role of culture in influencing the emerging adulthood period.

Government of Canada communications professionals work in an increasingly challenging environment, characterized by an intrusive 24/7 media cycle, a frenetic pace of evolving communication technologies, layered accountability requirements, political tension, and waning public trust. Scholars call on professional communicators to help rebuild public trust, which is intrinsic to a healthy democratic government. The Three-dimensional Model for Transparency in Government Communication developed by Fairbanks, Plowman and Rawlins (2007) serves as the theoretical framework for investigating the Government of Canada’s approach to transparent citizen-focused communications from the perspective of communications professionals. The model’s adaptability to the Government of Canada context is tested through 23 qualitative semi-structured interviews with Government of Canada senior communications advisors, managers and executives. The data is analysed using constant comparative thematic analysis. The findings demonstrate that Government of Canada communicators strongly value transparency. Furthermore, the key components of the transparency model – communications practices, organizational support and provision of resources – encapsulate the factors that influence the practice of transparent citizen-focused communications by the Government of Canada. The study concludes by offering recommendations for future research and practical applications.

Uppsatsen handlar om hur fyra judiska personer upplever antisemitism i Sverige. De har svarat på frågor som rör två teman, antisemitism och Israelkritik/antisionism. Informanterna har inte personligen utsatts för antisemitism i stor utsträckning, däremot upplever de att antisemitismen finns mer utbrett på andra platser i Sverige. Israelkritik upplever de enbart som antisemitism när den är obalanserad och när media anklagar judar kollektivt för vad som sker i Israel/Palestina. Sionism ser de dock ingen anledning till att kritisera eftersom den handlar om ett judisk självbestämmande. Ett par av informanterna anser att sionism är så starkt förknippat med judisk tradition att antisionism per automatik blir judefientlig. / The essay is about how four Jewish people experience anti-Semitism in Sweden. They answered questions related to two themes, anti-Semitism and Israel Criticism / anti-Zionism. The informants have not personally been subjected to anti-Semitism widely, but they feel that anti-Semitism is more prevalent in other parts of Sweden. Criticism of Israel is experienced as anti-Semitism when it is unbalanced and when the media blames Jews collectively for what is happening in Israel / Palestine. They see no reason to criticize Zionism because it is about a Jewish self-determination. A couple of respondents believe that Zionism is so strongly associated with Jewish tradition that anti-Zionism automatically becomes hostile towards Jews.
