This thesis consists of an introductory summary and three studies focusing language, interaction, and learning in multilingual schools. The overall aim of the thesis is to contribute to the understanding of student learning in diverse schools. The first study of the thesis examines the field of cooperative learning with the aim of summarizing, in an overview, research that addresses small group activities in heterogeneous classrooms. The overview indicates that this research is dominated by input-output studies. Process-oriented studies of student interaction constitute a smaller part of research within this field. The two subsequent studies were carried out in three multilingual middle school classes in Sweden. The second study concentrates mainly on the second language learners of these classes with the aim of describing language and learning conditions in actual classrooms. A main finding of the study is that second language students fell behind their monolingual Swedish speaking peers in social studies and in other subjects across the curriculum. The study also shows that students form separate groups of Swedes and immigrants inside as well as outside the classroom. The third study investigates small group activities in the above mentioned classes. The aim of the study is to gain insight into students’ joint problem-solving processes and thereby provide a broader understanding of learning as socially and interactionally constituted. The data consists of video recordings of small group conversations from which language-related episodes were identified, transcribed and studied applying conversation analysis methods. The findings show that the students are able to scaffold each other effectively in co-constructing linguistic knowledge through social interaction. At the same time, negotiations of power and status are included in their problem-solving processes.

隨著世界地球村的概念發展，各國家族群間的文化也漸趨多元，而多元文化主義的興起，主要就是為解決一國之內多元族群間的文化差異造成的問題。近年在英國、挪威、法國發生了幾起相關的社會事件；在瑞士也出現過禁蓋伊斯蘭教宣禮塔的新聞；而法國、比利時則有禁戴伊斯蘭面紗的法案。因此多元文化主義的實行方向在歐洲又重新引起軒然大波，歐洲各國也紛紛開始檢視國內多元文化主義政策及未來發展。 本研究探討比利時政府在面對境內不同語區的文化迥異時，如何推動多元文化主義政策。研究中介紹比利時多元文化主義政策之各基礎面向、分析雙語族群間的歧異點，並藉由禁戴伊斯蘭面紗法案來探討比利時對待國內少數族群的態度。以上述層面來總結比利時多元文化主義發展及挑戰，希冀本研究提供臺灣在面對本土、新移民等文化融合時可做為參考、借鏡。 / With the development of the concept of “global village” , the cultures within the nation have become diverse, and the rise of “multiculturalism” is to solve the problem of cultural differences in the multi-ethnic states. In recent years, the social events in the United Kingdom, Norway, and in Switzerland, there is the ban of the mosque minaret; also in France, Belgium there is the ban of “burka”. Since the implementation of multiculturalism again caused an uproar in Europe, european countries have also begun to review the policy of multiculturalism and its future development. This study examines how Belgian government promotes the policy of multiculturalism when facing the cultural differences between the two linguistic areas. It introduces Belgium’s policies of multiculturalism and the discrepancy points among the bilingual populations, and examines how Belgium confronts domestic minorities through the burka ban act. By summarizing the developments and challenges from the above mentioned, hope this study can provide a reference for Taiwan in the face of cultural integration.

This study examines the experiences of nine hijabi and non-hijabi Muslim girls from diverse backgrounds with curriculum/schooling in public secondary schools in Ontario. The study uses individual interviews and a focus group discussion to delve into how Muslim girls understand their educational experiences. The participants were independent, thoughtful, and conscientious students who were evolving as individuals through their curriculum/schooling experiences. School was a forum where they questioned themselves, discovered their interests, and made sense of their multiple identities. The differences between a participant’s home and school life varied, and each girl had a unique manner in dealing with the various ideological and practical conflicts. As Muslim girls, they were confronted with certain challenges in school; however, this did not detract from the overall positive aspects of their public schooling experiences. My participants felt respected and validated as individuals in their schools and optimistic regarding their futures as Muslim Canadian females.

The purpose of this multicase study was to describe and explain the perceptions of three Spanish-English culturally and linguistically diverse (CLD) high achievers on their biliteracy journeys to become educators in the United States (U.S.), by answering: What elements constitute the perspectives of three L1-Spanish/L2-English CLD high achievers on the relevance of their biliteracy experience in order to become educators in the U.S.?; What factors do these three L1-Spanish/L2-English CLD high achievers perceive as key to describe their biliteracy experience?; What relevance, if any, do these three L1-Spanish/L2-English CLD high achievers perceive their biliteracy experience had for them to become educators in the U.S.?; From the perspectives of these three L1-Spanish/L2-English CLD high-achiever educators, what impact, if any, did digital technologies have on their biliteracy experience? With a critical-pedagogy approach to multicase-study (Stake, 2006) inquiry, I used online methods to collect data on three high-achieving (GPA > 3.01) L1-Spanish graduates initially identified as limited-English-proficient by the American school system. For data collection, I used a participant-selection questionnaire, individual and group semi-structured interviews via Skype, e-journals for biliteracy autobiographies, artifact e-portfolios, my reflective e-journal, and one face-to-face unstructured interview with one participant only. Concurrently, I engaged in on-going data analysis to build meaning inductively and guide further data collection, analysis, and interpretation, until saturation, in an application of the dialectical method into research (Ollman, 2008). I included the email communications with the participants and their member checks. Two external auditors reviewed all data-collection and analytic procedures. I analyzed each case individually followed by the cross-case analysis. The findings indicated the importance of family and L1-community support, host-culture insiders as mentors, access to information, empowerment by means of conscientization, and the participants' advocacy of others by becoming educators. In this way, the study identified how the participants escaped the statistics of doom, which helps understand how to better serve growing L2-English student populations. The study closed with a discussion from the viewpoint of reviewed literature and critical pedagogy, my interpretation of the findings, and suggestions for future praxis in education and research.

A large number of English language learners (ELLs) in secondary school are long-term ELLs who have attended public schools in the United States for at least seven years, having received English language support services, yet have not acquired English proficiency (Capps, Fix, Murray, Ost, Passel, & Herwantoro., 2005). Formal or informal programs and educational services to address the particular needs of long-term ELLs are scant to non-exist (Zehr, 2010). In spite of the growing presence of long-term ELLs in secondary schools, little research has been conducted about their academic challenges. Due to the scarcity of research, effective practices for long-term ELLs in secondary school are very limited (Ruix-de-Velasco & Fix, 2000). Research is needed to better understand risk factors associated with dropping out, retention, and the high incidence of disproportionate representation of long-term ELLs in special education programs. Equally absent from available literature are the voices of students themselves. This study aims to expand the existing database about long-term ELLs' academic challenges from the perspective of students themselves about their language and academic learning experiences. A qualitative, naturalistic inquiry (NI) approach was utilized to explore the perceptions of long-term ELLs about their learning experiences in the context of their school history, including program placements, special education referral, and academic outcomes. Thirteen long-term ELLs at a high school in metropolitan area of Texas were participated in this study. Data were generated from semi-structured, in-depth interviews and various documents, including students' cumulative folders, language proficiency assessment records, and the state assessment data, and analyzed using a grounded theory approach. The findings of the study indicate that participants experienced multiple layers of lack of opportunity to learn as they moved through the educational process. Participants perceived themselves as English-proficient, motivated learners who were successful in spite of challenges they had experienced, which they attributed mainly to their limited development of academic language proficiency in English. The study also revealed a gap between participants' postsecondary aspirations and the reality of their academic underachievement, which raises questions about the adequacy of general educational programs for this population and appropriate identifications of ELLs with disabilities. / text

Waste, that is any matter whether gaseous, liquid or solid or any combination thereof, originating from any residential, commercial or industrial area identified as undesirable or superfluous by-product, emission, residue or remainder of any process or activity tends to be a hazard to the environment. Waste is generated in all processes which transform materials from one state, form or medium to another. The management of waste in the Sedibeng District Municipality is a very complex problem. There are many reasons for this and these include: the diverse and voluminous waste stream; progressive accumulation of waste in the environment; large numbers of unpermitted waste disposal sites; the severe shortage of hazardous waste disposal sites and shortage of personnel in local municipalities qualified to implement existing legislation. The accumulation of waste in the district not only poses a serious and growing threat to health and quality of life, but also causes infrastructural damage such as the blocking of storm water drains and sewer by litter which ultimately leads to costly road and pavement destruction and increase in maintenance costs. The objective of the study was to investigate waste management activities in the Sedibeng District Municipality and to explore best practices as strategies for recommendations. The Sedibeng District Municipality comprises three local municipalities namely the Emfuleni, Lesedi and Midvaal Local Municipalities. Due to the fact that the Municipality forms part of the industrial hub of the Gauteng Province, there has been an excessive influx of the people into the district and, as a result, more houses had to be built and more normal urban services such as electricity, sanitation, water and waste, had to be provided. The study intended to investigate different waste management strategies that are employed by the three local municipalities that could help reduce the impacts and volumes of waste that are generated by residents before such waste could pollute the environment. A further objective was to explore possible waste reduction mechanisms such as recycling that can help reduce waste volumes before they reach the disposal site. Arising from the problem statement on waste management for this study, it is important that the locus of this study be directed towards the solution of the problem on waste management activities in the Sedibeng District Municipality The following hypothesis was accordingly formulated: Waste management strategies and practices as currently practised in the Sedibeng District Municipality are obsolete, outdated and inadequate to attain a cleaner environment and as a result, there is a need to explore the development of more cost effective strategies in waste management. Comparative study of the different strategies that are employed in the three local municipalities as well as the challenges they face when providing the required service, were made. Similar study was applied to the achievements that are recorded as findings of the study. The challenges and success stories highlighted in the study were found through the use of questionnaires that were distributed to respondents in the three local municipalities. Questionnaires for the study were compiled for both councilors and municipal officials. The research instruments for the study included questionnaires, interviews and consultations with members of the community. Further technique was participant observation, the researcher being responsible for the provision of refuse removal services to the Evaton and Sebokeng communities. Amongst others, it was found that: discrepancies existed in the waste management processes and these include the following: • There was a serious problem of personnel shortage in municipalities as a result of financial constraints that led to nonreplacement of personnel who went on retirement, resigned or died; • Existing equipment do not compliment the growing population figures as well as the sizes of the municipality and as a result, residents opted to dump waste at their backyards as an alternative procedure for disposal of waste from their homes, and • Problems attributed to illegal dumping increase each day and their resolution will be a function of implementation of compliance with legislation. • Community awareness of refuse collection schedule is at minimum, a situation which leads to illegal dumping of waste, and • Tariff on refuse removal is deemed to be prohibitive to African residential areas. The study ends with recommendations for management action on waste, and for further research. / Thesis (Ph.D. (Public Management and Administration))--North-West University, Vaal Triangle Campus, 2010.

The thesis approaches the issue of IS support for service work, understood as distributed knowledge work taking place as a negotiation between diverse interests. It is based on an ethnographically inspired, longitudinal case study of certification auditing according to a formal generic standard. A handful of certification auditors are followed closely, periodically and comprehensively over three years. Observations are combined with interviews of subjects and colleagues, added by exploration of other material. The practices of company ‘W’ is placed within a larger historical and institutional context. Research literature and theory is explored in four chapters from Social studies of science (STS), Computer supported cooperative work (CSCW), Information systems (IS), Information infrastructures (II) and Management literature. The aim is to identify basic characteristics of service work, its opportunities and challenges, from both the company’s and workers’ perspective. Main topics are Decision Making as negotiated sensemaking, contextual rationality and judgement; Sharing of understanding and meaning as ongoing practiced articulation work aiming for trust and an equifinal level of accord that will ‘find and allow common action’; Perseverance in a capable role that will allow calibration of distributed knowledge is vital for auditors. Common Information Spaces (CIS) is used as a framework to explore the heterogeneous circumstances of identity work in work practices; Predictability in production is sought through various strategies of standardization. Approaches to avoid and counter the inherent side-effects of standardization are described. The empirical results of the research project are presented and analysed in four chapters that look at the issue of i) being an accomplished service worker and ii) practicing service work. Both issues are addressed from a local, individual perspective, and from an organizational perspective in terms of the continuation of quality production. The thesis closes with a Conclusion of organized and standardized service work as displaying Practical drift, in response to the research question RQ0. How is IS supported distributed service work negotiated?, followed by implications for IS research and practice. The empirical case displays the role of information systems (IS) support in distributed service work - as part of a larger assembly of standardization measures, a broad-spectrum approach, displaying practical drift in its effect. The service work of certification auditing is characterized by ongoing negotiation of partly contradictory interests. It is heterogeneously standardized through material, rational/immaterial and social/organizational measures, many in place long before the advent of advanced IS. Traditionally, there are release mechanisms that, on the auditors’ discretion, alleviate the inappropriate effects of standardization. With new harmonising efforts the scope of this personal latitude needs to change, but when first implemented the IS along with new procedures start off as too tight. However, over time adaptations are made, making the overall process self regulatory with feedback mechanisms. On the whole, the thesis aims to contribute to the literature on information infrastructures, on knowledge work in general, and CSCW by drawing on insights from this specific collaborative work in controversial settings. The case provides practical insights for resilient systemizing of knowledge based global service work practices.

Doctor of Public Health / For many years the major cause of infant mortality in NSW has been the result of Sudden Infant Death Syndrome (SIDS). Statistics show the area defined as 'Western Sydney' is no exception, and in 2002, a report prepared by the Epidemiology, Indicators, Evaluation and Research Unit (EIRE) in Western Sydney presented data indicating SIDS rates in the area were higher than the state average. In particular, two Local Government Areas (LGAs) had clusters of SIDS deaths. Previous Australian research identified a higher risk of SIDS and other causes of infant mortality in Aboriginal and Torres Strait Islander populations. The areas of Western Sydney where SIDS rates were higher than expected were home to Aboriginal, Torres Strait Islander and Pacific Island residents. The number of SIDS deaths in Aboriginal infants did not explain the higher than expected rate of SIDS in the areas under investigation. Studies undertaken in New Zealand and the Pacific Islands have identified higher than expected risk of SIDS in Maori and Pacific Island communities in those countries, although this has never been studied in Pacific Island residents living in Australia. The reasons for these communities exhibiting a higher than normal SIDS rate is not completely understood, but can be partially explained by behavioural practices which are known to impact adversely on the risk of SIDS. This study sought to investigate the level of knowledge concerning the prevention of sudden and unexpected death in infants (SUDI) in three key groups of infant caregivers: general practitioners, nurses and parents living or working in the area geographically defined by Sydney West Area Health Service (WSAHS). In addition, the study sought to identify any variation in knowledge of SIDS reduction strategies in the three groups under study, and to investigate factors influencing knowledge and practice in these participants. The study findings were then used as a basis on which to develop strategies and recommendations to enhance the delivery of safe sleeping messages through the health care system. Using a combination of qualitative and quantitative methods, this cross-sectional study highlights a number of issues around infant care practices and the major influences on new parents living in a multicultural community. Results of the study showed there is a large variation in knowledge around safe sleeping practices (including SIDS reduction strategies) in all the groups studied. Although educational campaigns are conducted regularly, many general practitioners and parents are confused about the key SIDS reduction messages and still place infants in sleeping positions considered unsafe. While nurses and midwives were aware of the SIDS reduction strategies, they still occasionally used infant sleeping positions considered unsafe. General practitioners born overseas in a country where English is not the first language were less likely to be familiar with safe sleeping messages, including SIDS reduction strategies. Families from a Culturally and Linguistically Diverse (CALD) background were less likely to have seen SIDS information in their own language than families who spoke English, and as a result were more likely to use traditional methods of infant care, including co-sleeping with siblings and parents and side or tummy sleeping. CALD parents were more likely to rely on herbal remedies and friends and family for assistance, than English speaking parents who accessed health professionals as the first point of call when infants were unwell. The study identified a relatively recent practice, which until reported in this study, has not been documented in the literature. The practice of draping infant prams with blankets originated from the Cancer Council of Australia guidelines which recommend covering a pram with a light muslin wrap to protect infants’ skin from the sun. It appears parents have misinterpreted this message and are covering infant prams with blankets to encourage sleep, even when sun exposure is not an issue. Research suggests that poor air quality around the head of an infant may affect an infant’s arousal response. While no research has been conducted on the air quality around an infants head when covered by a heavy blanket in a pram, it is possible based on research into air quality around infants, that that this practice may increase the risk of sudden and unexpected death in an infant. In conclusion, this study found that multiple changes to the SIDS reduction messages since the initial ‘Reduce the Risks’ Campaign have led to confusion about ways of preventing SIDS in GPs, nurses and parents in Western Sydney. The study makes seven recommendations aimed at improving knowledge of safe sleeping practices in these groups, and optimizing health outcomes for infants using a collaborative approach to service delivery and future initiatives.
