Full textAbstract:
Spark ignited engines are still important for conventional as well as for hybrid power trains and are thus objective to optimization. Today a lot of functionalities arise from software solutions, which have to be calibrated. Modern engine technologies provide an extensive variability considering their valve train, fuel injection and load control. Thus, calibration efforts are really high and shall be reduced by introduction of virtual methods. In this work a physical 0D combustion model is set up, which can cope with a new generation of spark ignition engines. Therefore, at first cylinder thermodynamics are modeled and validated in the whole engine map with the help of a real-time capable approach. Afterwards an up to date turbulence model is introduced, which is based on a quasi-dimensional k-epsilon-approach and can cope with turbulence production from large scale shearing. A simplified model for ignition delay is implemented which emphasizes the transfer from laminar to turbulent flame propagation after ignition. The modeling is completed with the calculation of overall heat release rates in a 0D entrainment approach with the help of turbulent flame velocities. After validation of all sub-models, the 0D combustion prediction is used in combination with a 1D gas exchange analysis to virtually calibrate the modern engine torque structure and the ECU function for exhaust gas temperature with extensive simulationsModerne Ottomotoren spielen heute sowohl in konventionellen als auch hybriden Fahrzeugantrieben eine große Rolle. Aktuelle Konzepte sind hochvariabel bezüglich Ventilsteuerung, Kraftstoffeinspritzung und Laststeuerung und ihre Optimierungspotentiale erwachsen zumeist aus neuen Softwarefunktionen. Deren Applikation ist zeit- und kostenintensiv und soll durch virtuelle Methoden unterstützt werden. In der vorliegenden Arbeit wird ein physikalisches 0D Verbrennungsmodell für Ottomotoren aufgebaut und bis zur praktischen Anwendung geführt. Dafür wurde zuerst die Thermodynamik echtzeitfähig modelliert und im gesamten Motorenkennfeld abgeglichen. Der Aufbau eines neuen Turbulenzmodells auf Basis der quasidimensionalen k-epsilon-Gleichung ermöglicht anschließend, die veränderlichen Einflüsse globaler Ladungsbewegung auf die Turbulenz abzubilden. Für den Brennverzug wurde ein vereinfachtes Modell abgeleitet, welches den Übergang von laminarer zu turbulenter Flammenausbreitung nach der Zündung in den Vordergrund stellt. Der restliche Brennverlauf wird durch die physikalische Ermittlung der turbulenten Brenngeschwindigkeit in einem 0D Entrainment-Ansatz dargestellt. Nach Validierung aller Teilmodelle erfolgt die virtuelle Bedatung der Momentenstruktur und der Abgastemperaturfunktion für das Motorsteuergerät

Nowadays, the nature of the projects has changed to be unique, uncertain, ambiguous,complex and innovative. It becomes hard to plan in advance the project progress, asdeviations from plans and unpredictable changes occur more frequently. This can bespecifically observed in the software development industry which needs to constantlymeet customers’ rapidly changed requirements. Traditionally, software projects aredeveloped through a plan-driven approach which emphasizes an overall project plan andcontrol process in terms of project management. Recently, this has been challenged byagile approach that focuses on flexibility to quickly meet changing requirements, andthese new agile methods provoked huge interest and got more and more popular andwidely applied especially in IT industry. However, the popularity does not mean theagile methods have advantage over traditional plan-based project management methods.In fact, both methods have own advantages and disadvantages and cannot be fullyreplaced by each other. Therefore, it becomes important and necessary for companymanagement to know how to select a suitable method for the new software developmentproject to get the maximum benefits.The purpose of this study is to describe different project management methods(traditional plan-driven and agile methods) and their various consequences for themanagement of software-development projects. Additionally, a more practical purposeis to suggest on what grounds a choice between methods may be made. Morespecifically, this research aims to provide the possible solution on how to selecttraditional plan-driven or agile project management method for managing a newsoftware development project. The research conducted a qualitative study in a casecompany of IT industry through several semi-structured interviews and questionnaireswith experienced and knowledgeable employees. It started with the analysis andcomparison of traditional and agile project management methods’ characteristics andapplication domains based on two specific examples (PROPS and Scrum) selected fromtraditional and agile project management methods respectively, in order to identify a setof preliminary outstanding characteristics which could be used to help IT company tochoose project management methods for new software development projects. Theempirical data obtained from interviews of case company was investigated to verifythese characteristics based on the literature review, and further adjusted thecharacteristics identification. After going through the whole research process, finallyresearchers identified the most suitable characteristics that were important both intheory and practice to examine on what ground a software development company needsto base the selection of project management methods. These suitable characteristics are:Project Complexity, Communication, Competencies and Requirements, in order to helpselect the best management way for the specific project.

Tookey, Sara Angela. "Help-seeking for potential symptoms of gynaecological cancer amongst obese women : a mixed methods study." Thesis, University of Birmingham, 2016. http://etheses.bham.ac.uk//id/eprint/6771/.
Full textAbstract:
Obesity is associated with an increased risk of developing some gynaecological cancers, and delayed help-seeking. The thesis aims were to identify factors predictive of delayed help-seeking for women seeking help for potential symptoms of gynaecological cancers, particularly looking at the role of obesity on time to help-seeking. Qualitative and exploratory research further investigated health beliefs and help-seeking attitudes of women experiencing gynaecological cancer symptoms and built a framework for understanding women’s complex journeys toward medical help-seeking. Additionally, the research assessed for differences in time to help-seeking and cancer awareness across groups with varying body mass indexes (BMIs) and different ethnic groups. Findings suggested that women have a limited awareness of gynaecological cancers, nevertheless, low awareness of gynaecological cancers was not associated with help-seeking delay. Thesis studies showed that obese women were not more likely to delay help-seeking when compared to non-obese women, and that attendance at preventative screenings was a predictor of delayed help-seeking. In conclusion the thesis provided an understanding of the often-complex transition through the menopause and challenged assumptions in the literature about the association between obesity, help-seeking and preventative screenings. Future research should further explore the complex relationship between BMI and help-seeking for gynaecological cancer symptoms.

Full textAbstract:
This thesis analyses the scope for the “self-help” model of rural development to succeed in its broadly stated aims of enabling rural women to advance their social status and enhance their own and/or their family’s livelihoods. The thesis is organised around two key sites of investigation. The first questions the potential for “self-help” to operate within existing social relations - expressed in access to land, other assets and resources (including credit), and in different forms, conditions, and relations of labour. The second questions its potential to intervene in, and potentially overturn, these relations. These questions are embedded in a wider analysis of the ways in which individual and collective attempts to advance living conditions (or at least defend them from deterioration) are defined by historically (re)produced social relations. Analysis is centred on the South Indian State of Andhra Pradesh, where the “self-help” policy approach, now widely replicated as a model for central and federal interventions, is most established. This is a mixed-methods study. It draws on statistical analysis of large-scale secondary survey data, analysis of primary fieldwork, and of government policy documents and other relevant documentation. The thesis engages directly with the philosophical issues this raises, to develop a foundation for the logically consistent assimilation of statistical and “qualitative” methods into mixed methods research. Fieldwork centred on two villages in southern Chittoor district and relied primarily on repeated in-depth interviews with members of four self help groups and, where applicable, their husbands (30 respondents in total). Local officials and programme staff and bank managers were also interviewed. In addition, multi-level logit regression analysis was conducted with two large-scale, complex secondary data sets; the All India National Survey Sample (round 61; schedule 10; 2004/05) and the Young Lives Project Survey (round two; 2005/2006). An innovative weighting procedure was applied to adjust for the latter’s non-random sampling procedure.The findings demonstrate the tensions invoked by state policy emphasising agential action in the absence of due regard for the structural relations within which actions not only take place, but in which the conditions for their possibility and articulation are generated, institutionalised, and reproduced. This situation is exacerbated by unfolding ecological crisis in the fieldwork village sites, problematising the land-based solutions traditionally advocated by the Indian Left. The thesis concludes that Andhra’s self-help programmes can perform a non-trivial ameliorative role in the short-term, but this is undermined by a wider tendency to reproduce and potentially exacerbate ongoing processes of rural differentiation.

Full textAbstract:
As social media platforms are increasingly becoming more popular and a part of everyday life, Business-to-Business (B2B) marketers from different industries are realizing social media’s potential for achieving marketing purposes. However, scientific literature regarding social media usage in B2B contexts is still filled with gaps in knowledge; especially when compared to literature about social media usage in Business-to-Customer (B2C) contexts. One of these research gaps is the lack of niched information about each effect of using social media. This paper aims at contributing to filling this research gap by presenting an extensive literature review about social media marketing in B2B; followed by an analysis of empirical data gathered from 11 different cases of B2B companies engaged in social media marketing. Moreover, this is to answer the research questions; how are B2B companies using social media to increase brand awareness? Which types of content inspire the most customer engagement? And how can B2B companies amplify their chances of succeeding in increasing brand awareness through social media? This paper will further contribute to this research topic, by identifying further research gaps and present suggestions for future research.

Full textAbstract:
Universities make claims about student learning that graduates don't often achieve and are under pressure to show improvement in teaching and learning in their undergraduate programs. This has been the constant focus of university-level professional development programs, but most teachers are still not using the most effective teaching methods. Individual departments need to find ways to help their instructors overcome three main challenges associated with adopting more effective student-centered teaching methods. No matter what strategy is adopted, instructors need considerable support to 1) change their beliefs about what constitutes effective teaching and learning, 2) learn to effectively implement new strategies, and 3) help their students change their beliefs about teaching and learning. We investigated whether M.S. Geoscience Education graduate students could offer the support instructors need to overcome the challenges listed above. We successfully piloted this approach during 2006 to 2008. Receiving consistent and individualized support from a Geoscience Education graduate student, the instructor changed his beliefs about teaching and learning and learned to effectively implement active learning strategies. His teaching satisfaction and student ratings also increased. Advantages of our approach include 1) the time the graduate student devoted to making course changes, 2) the consistent support the instructor received which allowed him to transfer research supported educational theory into his teaching practice, and 3) the instructor is now a departmental resource that other instructors can go to for guidance. Disadvantages include 1) the graduate student's lack of experience as a teaching consultant and 2) the difficulty of transforming a professor/student relationship into a client/consultant relationship.

Yip, Wai Chi. "Communicating social support in online self-help groups for anxiety and depression : a mixed methods discourse analysis." HKBU Institutional Repository, 2020. https://repository.hkbu.edu.hk/etd_oa/732.
Full textAbstract:
Most studies on online self-help groups for healthcare contexts have explored the content of social support. However, very little research has shed light on the communicative behaviors and language use of participants in online self-help groups for mental illness. This thesis studies the communication of social support in online self-help groups for anxiety and depression (OSGADs) to reveal their characteristics as communities of practice (CofPs) and how the predominant communicative acts of the participants contribute to social support communication. The data of the present study is a self-compiled corpus of 120 threads collected from six selected OSGADs. Mixed methods discourse analysis (MMDA) is used as a research method to conduct three empirical studies (i.e., Chapters 4, 5, and 6), in which both qualitative and quantitative approaches of discourse analysis are utilized, including content analysis, textual analysis, and interaction analysis. Different analytical frameworks are employed in the analyses. The data analysis begins by investigating the main communicative patterns of the interactions (Chapter 5) and then examines two predominant communicative acts (Chapters 5 and 6). Issues closely related to the analysis are also discussed in each of the analytical chapters. Using conversation analysis (Jefferson & Lee, 1992) and Social Support Behavior Code (Coulson, 2005), Chapter 4 reveals the sequential structures and main content of the interactions. The results show that self-disclosure and advice-giving are the most predominant communicative acts in the interactions. This chapter argues that the optimal matching theory (Cutrona & Russell, 1990) is probably inadequate to elucidate that the support proffered by respondents aids the support seekers. Chapter 5 investigates the multiple functions of self-disclosure in personal, textual, and interactional layers. The functions are examined through textual analysis and interaction analysis in tandem with frameworks including cognitive discourse analysis (Tenbrink, 2015) and rhetorical structure theory (Mann & Thompson, 2009). The findings show that self-disclosure enables support providers to distance themselves from problems, release their emotions, and increase reliability/persuasiveness. Self-disclosure facilitates the disclosure of other participants and support recipients may perceive it as advice, mitigation, and normalization. Chapter 6 conceptualizes the politeness of advice messages. Viewing advice as a speech event, textual analysis is conducted to explore the discursive moves and relational strategies (Locher, 2006) in advice messages, and shows that the advice messages contain many emphatic moves and relational strategies, including sharing own experience, empathizing, and assessment. The notions of contextualization (Gumperz, 1987) and relational work (Watts, 2003) are used to argue that empathy is a contextualization cue to make the advice messages appropriate and politic. Based on the three empirical studies, this thesis suggests three main characteristics of OSGADs as CofPs, including an emphasis on supportiveness, participants' performance of multiple identities, and frequent self-disclosure and advice. This thesis argues that self-disclosure is particularly crucial in the social support communication due to its multi-functionality. Self-disclosure is also an act that contextualizes an empathetic interactional context wherein advice is often politic and appropriate. This thesis concludes by discussing implications for interpersonal communication and online support groups in Hong Kong

Full textAbstract:
Overview This volume is separated into three parts: • Part 1: Literature review. A systematic review and meta-analysis of twelve randomised controlled trials that examined the efficacy of psychological treatment for vaginal pain. The aim was to understand whether efficacy of treatment differed for vaginal pain defined as medical or psychiatric in aetiology. Differences and similarities in efficacy were examined on outcomes of pain and sexual function. Effectiveness of psychological treatment was found to be comparable regardless of aetiology, indicating that this distinction may not be helpful for informing treatment decisions. • Part 2: Empirical paper. A mixed methods study evaluated a new computerised programme for six women with vaginismus. Change in pain-related fear, penetration behaviour and pain intensity was quantitatively assessed. Interviews were used to qualitatively explore acceptability and change. Pain-related fear and pain intensity reduced over the course of the programme; successful penetration increased. The programme was experienced as convenient, gradual, and supportive, with moments of frustration at progress. The programme also had a positive influence on self-awareness, confidence, normalisation, and approach behaviours, with exposure attributed as the most difficult but important aspect of change. • Part 3: Critical appraisal. An appraisal of methodology used in the empirical study, discussing the potential biases encountered with research allegiance.

Day, Ruth Isobel. "The value of focusing : a psychological self-help strategy when living with chronic low back pain : a mixed methods study." Thesis, Bournemouth University, 2009. http://eprints.bournemouth.ac.uk/14995/.
Full textAbstract:
Chronic low back pain (CLBP) is a widespread and disabling condition affecting many thousands of people in the UK, causing distress in many areas of their lives. Most people with CLBP do not have access to specialist advice and resort to managing it themselves. The government drive to encourage people to manage their own long-term conditions has led to some work on the use of self-help techniques with CLBP. However little research has been done with CLBP populations who are not seeking specialist advice. This study actively sought people from this population group. Focusing - a self-help technique based on the client-centred psychological approach - was introduced to two people who had long-term CLBP. In addition two people who had been using Focusing in their lives for some time and have long-term CLBP (but have not applied Focusing to that problem) were also recruited. Focusing was taught either face-to-face or by telephone for six weekly hour-long sessions; the experienced Focusers spent an hour each week for six weeks Focusing with their pain. Using a mixed methods approach the four participants were interviewed a number of times, namely before, immediately after and three to six months following the Focusing sessions. They also completed the WHOQOL-PainUK questionnaire, the short-form McGill Pain Questionnaire and a global QOL measure at these three times. During the Focusing sessions they completed the SF-MPQ and the global QOL weekly. Within the concurrent nested design the qualitative aspect formed the theoretical driver for the study; the quantitative element providing a smaller amount of data. This enabled the findings to be framed in a way which makes them accessible to the wide range of healthcare professionals involved in the management of CLBP; an approach described as one of 'utility'. The management of potential incongruencies in using a mixed method approach was a continuous theme throughout the study and a model - the context of stability model - was devised to enable a harmonisation of these in the study design.During the study three of the four participants reported a change in the meaning of their pain, and improvement in the perception of their pain and its impact. After using Focusing with their CLBP participants reported that the pain no longer controlled what they did, they were able to feel more 'themselves' and value themselves and Focusing had given them a supported place to talk about their pain. Focusing appears to have an impact for these people in enabling the acceptance of CLBP and an improvement in overall quality of life was found. The physical, psychological and independence quality of life domains in particular showed sustained improvement. No negative side effects were noted by any of the participants. Further study is needed to demonstrate whether the use of Focusing with CLBP confers longer term benefits and is suitable for a wider range of people.

Objective(s). An increasing demand exists for psychological interventions to increase recovery from depression and anxiety in people with long-term physical health conditions (LTCs). Guided self-help (GSH) may meet this need, however, there is limited evidence of GSH’s appropriateness for people with LTCs. Design. A mixed-methods study using qualitative interviews with people with stroke and Chronic Obstructive Pulmonary Disease (COPD), and a quantitative survey of professionals who support guided self-help, explored opinions about whether self-help is appropriate, and whether suggested adaptations varied across LTCs. Results. Opinions varied about the appropriateness of standard self-help and adaptations required. Illness beliefs may help explain differences between the two LTCs and individual interviewees. The majority of professionals surveyed felt competent supporting people with LTCs, and reported having access to appropriate self-help material. Conclusions. Recommendations for improving the appropriateness of contents of guided self-help for people with LTCs are provided. Supporting professionals need relevant knowledge and skills to integrate information about the LTC into the intervention, and offer flexible, personalised delivery to support participation.

Full textAbstract:
Chinook salmon (Oncorhynchus tshawytscha) are critical to subsistence and commerce in the Yukon River basin, but several recent years of low abundance have forced devastating fishery closures and raised urgent questions about causes of the decline. The Chena River subpopulation in interior Alaska has experienced a decline similar to that of the broader population. To evaluate possible factors affecting Chena River Chinook salmon productivity, I analyzed both population data and the behavior of individual fish during the summer they spend as fry drift feeding in the river. Using a stereo pair of high definition video cameras, I recorded the fine-scale behavior of schools of juvenile Chinook salmon associated with woody debris along the margins of the Chena River. I developed a software program called VidSync that recorded 3-D measurements with sub-millimeter accuracy and provided a streamlined workflow for the measurement of several thousand 3-D points of behavioral data (Chapter 1). Juvenile Chinook salmon spent 91% of their foraging attempts investigating and rejecting debris rather than capturing prey, which affects their energy intake rate and makes foraging attempt rate an unreliable indicator of foraging success (Chapter 2). Even though Chinook salmon were schooling, some were highly territorial within their 3-D school configurations, and many others maintained exclusive space-use behaviors consistent with the population regulatory effects of territoriality observed in other salmonids (Chapter 3). Finally, a twenty-year population time series from the Chena River and neighboring Salcha River contained evidence for negative density dependence and a strong negative effect of sustained high summer stream discharge on productivity (Chapter 4). The observed territoriality may explain the population's density dependence, and the effect of debris on foraging efficiency represents one of many potential mechanisms behind the negative effect of high stream discharge. In combination, these findings contribute to a statistically and mechanistically plausible explanation for the recent decline in Chena River Chinook salmon. If they are, in fact, major causes of the decline (other causes cannot be ruled out), then we can be tentatively hopeful that the population may be experiencing a natural lull in abundance from which a recovery is possible.

Full textAbstract:
The effects of goal interdependence on employees’ performance outcomes have been well documented in the literature. Yet, the relationship between goal interdependence and employees’ proactive behaviors remains largely unexplored. Integrating the theory of cooperation and competition with the employee proactivity literature, this study investigates how cooperative goal interdependence and competitive goal interdependence respectively influence employee knowledge sharing and knowledge hiding, and in turn shape their propensity to seek help from coworkers. It further examines reciprocity beliefs as an individual factor in affecting the indirect effect of goal interdependence on help seeking. Specifically, positive reciprocity belief is hypothesized to moderate the mediating role of knowledge sharing, whereas negative reciprocity belief is expected to moderate the mediating effect of knowledge hiding.
In Study 1, a total of 127 interviews were conducted with full-time employees working in professional service firms across four cities including Hong Kong, Macau, China and Taiwan. Results of structural equation modeling supported the mediating role of knowledge sharing in the relationship between cooperative goal interdependence and employee help seeking.
In Study 2, an experimental study was conducted with 150 full-time students at a university in Macau to replicate the findings in Study 1 and to test the moderation hypotheses. It yielded findings consistent with Study 1 and supportive of the moderating role of negative reciprocity belief in the mediated effect of goal interdependence on help seeking. Specifically, knowledge hiding mediates the relationship between competitive goal interdependence and help seeking, when an individual is high in negative reciprocity belief.
Findings of the two studies provide both theoretical contributions to the literature and practical insights to organizations. Cooperative goal interdependence is a valuable method for managers to promote knowledge sharing, inhibit knowledge hiding, and encourage active help seeking among employees.

Full textAbstract:
The purpose of this study was to determine whether Socratic questioning, an approach that builds critical thinking skills and fosters learning by constructing new knowledge, was an effective tool for improving student perceptions of the writing process. The main research question that was examined in this study was: How can Socratic questioning improve students' perceptions of writing and the writing process? Qualitative research methods were used as a framework for the design of this study as well as purposeful student sampling, triangulation of three data sources, and an extensive coding process. Findings from the study support that Socratic questioning can positively impact students: the first major finding was that student perceptions of the writing process improved, and the second major finding was that student perceptions of their own identities as writers improved as well. After the study, students found that being an effective writer was possible and that evaluation of one's writing was a vital part of becoming a better writer. Most importantly, after participating in this study, students believed themselves to be writers.

Full textAbstract:
Background: UK health policy has sought to encourage alcohol screening and brief intervention (ASBI) delivery in primary care, including via pay-for-performance (P4P) schemes. To measure the impact of such policies, a range of data exist, including General Practitioner (GP) Read codes, which record all clinical activity. However, previous studies have highlighted the difficulties of using Read code data for evaluation purposes, with concerns around the distorting effect of P4P on healthcare recording. Against this background, this research investigated whether Read code data can be used to provide a meaningful measure of ASBI implementation in primary care. Methods: Sequential mixed methods design, comprising: (1) systematic literature review to identify what factors influence the recording of routine clinical data by UK primary care physicians; (2) analysis of ASBI Read code data from 16 GP practices in North East England; (3) 14 GP interviews to explore the barriers and facilitators affecting their ASBI recording. Results: (1) Multiple factors shape primary care physicians’ recording of routine data, including structural influencers (such as the design and resourcing of the coding system), and psychosocial factors (including patient characteristics and physicians’ perspectives on their role as care-givers). (2) 287 Read codes exist to record alcohol- related activity however only a small minority are used regularly, generally relating to the identification of alcohol use disorders. Whilst many unused Read codes are associated with relatively rare alcohol conditions, a significant number relate to duplicate or outmoded terminology. Overall, practices associated with higher recorded rates of key ASBI service indicators were signed up to P4P schemes. (3) GP interviews suggested that across all practices, nurse-administered ASBI components were most likely to be provided and coded consistently, with GP-delivery and recording activity far more ad hoc. Conclusion: Whilst routine data may be a valid indicator of more successfully embedded ASBI activity in UK primary healthcare following the introduction of P4P schemes, measuring the impact on delivery at GP level remains challenging due to the deficiency of the available Read code data across a number of quality dimensions.

In a home environment, there are many tasks that a human may need to accomplish. These activities, which range from picking up a telephone to clearing rooms in the house, all have the common trend of fetching. These tasks can only be completed correctly with the consideration of many things including an understanding of what the human wants, recognition of the correct item from the environment, and manipulation and grasping of the object of interest.
The focus of this work is on addressing one aspect of this problem, decomposing an image scene such that a task-specific object of interest can be identified. In this work, communication between human and robot is represented using a feedback formalism. This involves the back-and-forth transfer of textual information between the human and the robot such that the robot receives all information necessary to recognize the task-specific object of interest. We name this new communication mechanism Interactive Text Response (ITR), which we believe will provide a novel contribution to the field of Human Robot Interaction.
The methodology employed involves capturing a view of the scene that contains an object of interest. Then, the robot makes inquiries based on its current understanding of the scene to disambiguate between objects in the scene. In this work, we discuss development of ITR in human-robot interaction, and understanding of variability, ease of recognition, clutter, and workload needed to develop an interactive robot system.

Full textAbstract:
Mental illness is not only the leading cause of disability among adults, but there is also an emerging public health crisis in childhood mental illness. A majority of parents do not recognize symptoms of psychological disorder in their children, and current policies and programs for mental health service delivery are not sufficiently responsive to the early help-seeking dynamics of families. Using a concurrent mixed methods design, this study explored how parents in the Pikes Peak region of Colorado learned to recognize their child's mental illness. Phenomenological interviews, augmented by poetic inquiry and quantitative measurements, were used to discover factors that inhibited or enhanced five mothers' recognitions. These factors were then evaluated using a frequency distribution analysis and a rank-order correlation. The phenomenon of recognition was, for these mothers, a process of waiting to hear that â??normalâ?? had stopped, wherein they miscategorized symptoms as normal behaviors in a passing developmental phase. Prior experience with mental illness appeared to significantly decrease both the length of time and the level of distress necessary for recognition. Ultimately, recognition did not occur until someone in their social network validated their concerns and provided explicit confirmation, which galvanized them to seek treatment. Governance network collaborations can facilitate positive social change by standardizing guidance on how to differentiate symptoms of a disorder from normal childhood development. Public policies and programs such as universal mental health screening, mental health literacy, and more supportive and responsive school policies can foster dialogue for parental recognition in Colorado and throughout the country.

Full textAbstract:
The main objective of the research was to understand hemp processing at different stages through numerical simulations. Processing of hemp materials involves breaking the hemp into different sizes of particles and separating those particles into fractions of different sizes. Numerical models were developed using the discrete element method (DEM) to simulate hemp processing using a hammermill and separations of different hemp particles using a 3D vibratory screen-type separator. The models were implemented using a commercial DE code, the Particle Flow Code in Three Dimension (PFC3D). In the models, virtual hemp, hemp fibre and core were defined using clusters of PFC3D basic spherical particles which are connected by the PFC3D parallel bonds. The microproperties (e.g. particle stiffness and friction coefficient, and bond stiffness and strength) of these particles were calibrated. For calibrations, virtual tests were performed using PFC3D for hemp stem, fibre, and core. Those virtual tests included direct shear tests of fibre and core particles, tensile tests of fibre, and compression tests of hemp stems. The microproperties of these particles were calibrated through comparing results from the virtual tests with results from laboratory tests or literature data. Those calibrated particle microproperties were used in the PFC3D models developed for simulating the hammermill for hemp processing and the 3D vibratory separator for particle separation. These two machines were constructed using various PFC3D walls and lines, and had the main features and operational conditions as the real machines. The hammermill model was able to predict the power requirement of hammermill and particle dynamic behaviours (kinetic and strain energies) within the hammermill. The separator model was capable of predicting the separation efficiency of the 3D vibratory separator for separations of different hemp particle mixtures. The behaviour of the models reflected the real behaviour observed experimentally. The model results were reasonably good as compared with literature data and the test results. The models developed have the potential to simulate many other dynamic attributes of hemp particles with the machines. This study has laid a solid foundation for future studies of biomaterial-machine interactions using the DEM.

Full textAbstract:
Background: The East Tennessee State University Quillen College of Medicine Library has participated for several years in projects to provide rural clinicians with health information resources.
Objectives: To determine whether a strategy of hand‐held devices with a best‐evidence point‐of‐care disease tool and a drug database paired with access to a medical library for full‐text articles and training to use the tools would be an affordable way to meet the information needs of rural underserved clinicians.
Methods: This study is a mixed‐methods methodology. The first project was evaluated using a randomised controlled trial (RCT) methodology. The second was evaluated qualitatively using interviews and focus groups.
Results: The quantitative findings discovered that clinicians equipped with a hand‐held device with evidence‐based software more frequently found answers to clinical questions, found answers more quickly, were more satisfied with information they found and use expensive resources such as continuing medical education, online databases and textbooks less than the group that did not have access to online technology. Qualitative results supported the quantitative findings. Conclusion: Librarians can implement a three‐pronged strategy of the secondary literature via a hand‐held, the primary literature via Loansome Doc and quality training to meet basic information needs of rural clinicians.

A point cloud derived from scanning the actual Vasa ship is used for an accurate visualisation. Both manual and automatic mesh techniques where utilized in the modelling of the Vasa ship to overcome problems of poor resolution in the point cloud and computing power. A combination of manual and automatic techniques resulted in a 3D model optimized for use within animation software. The method presented in this paper utilized a method that allows the user to keep control over topology. The polygon count is kept to a minimum and one can still remain certain that the measurements and realism from the point cloud is maintained.

Full textAbstract:
Entre 1972 et 1984, des non médecins du Mouvement pour la liberté de l’avortement et de la contraception ont pratiqué des avortements hors de la sphère médicale, dans le même temps que la professionnalisation de l’acte s’accélérait. Au moyen d’une ethnographie historique combinant un large corpus d’entretiens rétrospectifs et d’archives, la thèse s’intéresse à la politisation de l’avortement et éclaire sa constitution en problème de santé publique. Cette étude localisée de groupes MLAC ayant revendiqué une pratique propose une analyse incarnée à la fois de l’instauration du monopole médical sur l’avortement et des résistances à ce processus. Dans le temps de la lutte, médecins comme profanes participent à l’acclimatation et à l’adaptation en France de la méthode par aspiration. Il est remarquable que, des collaborations et conflits découlant de ces interactions, l’autorisation d’accès aux savoirs élaborés en commun ait échu aux seul⋅es détenteurs/rices de titres médicaux.La thèse constitue ensuite en objet d’étude le cas exceptionnel des MLAC qui ont maintenu une pratique profane après le vote de la loi sur l’IVG et renouvelé leur radicalité malgré la phase d’institutionnalisation dans laquelle sont entrés les acquis féministes. En remettant en cause tant la spécialisation des actes corporels que la domination patriarcale des corps féminins, ces « dissidentes » affirment progressivement l’orientation féministe de leur action. Au même moment, l’infusion du self-help en France soutient la réorientation de leur registre de revendication en enrichissant leur armature idéologique. La façon dont elles se l’approprient, alliée à la politisation de l’existence quotidienne des femmes et au développement de nouvelles pratiques de soins – les accouchements notamment –, invitent à considérer les MLAC dissidents comme une mobilisation de santéFrom 1972 to 1984, unskilled members (i.e. without a medical degree) of the Movement for the Liberation of Abortion and Birth Control aborted women outside medical spheres, whereas the practice was getting more and more professional. Thanks to a historical ethnography combining a wide corpus of retrospective interviews and archives, the thesis focuses on the politicization of abortion and highlights its constitution as a matter of public health. This survey of some local committees of the MLAC which claimed this practice puts forward a deep analysis of both the establishment of the medical monopoly of abortion and protests against this process. During the fight, physicians and unskilled practitioners take part in the introduction and adaptation in France of the aspiration method. We can notice that from collaborations and conflicts resulting from these interactions, the authorized access to the technical know-how learnt in common benefited only fully qualified physicians.The thesis then looks into the outstanding subject of the MLACs which maintained the practice outside medical structures after a bill was passed in favour of IVG – i.e voluntary termination of pregnancy – and resumed their radical militancy in spite of the institutionalization step including feminist achievements. By questioning both the specialization of practices on bodies and the patriarchal domination of female bodies, these « dissidents » gradually assert the feminist orientation of their action. At the same time, the spreading of self help in France supports the reorientation of their demands and enriches their ideological basis. The way they appropriate new orientations, plus the politization of women’s daily life and the development of new caring methods – notably deliveries (childbirths) – urge us to consider dissident MLACs as a mobilization for health

Full textAbstract:
Visual localisation and object recognition are key goals of artificial intelligence research that have been traditionally investigated separately. Appearance-based methods can be used to treat both problems from a common perspective. Therefore, the main purpose of this thesis is to explore appearance-based methods in the specific contexts of object recognition and visual localisation from wearable and hand-held devices. Specifically, the contributions of this thesis are as follows: The first topic of study was the object recognition of grocery products acquired with hand-held and wearable cameras, a use case of particular relevance for the blind and partially sighted people. The main contributions around this topic are a) the SHORT dataset, comprising 100 categories and more than 135,000 images between its training and query sets; and b) an open-source pipeline and complete evaluation of popular bag-of-visual-words (BoVW) techniques when tested against SHORT. The SHORT dataset is novel as it introduces a clear distinction between high quality training images and query images taken in the wild. This is an anticipated scenario in which retailers would acquire images for their online shopping brochures and users would submit images of unpredictable quality for recognition. The performance results of the methods tested demonstrate the challenging characteristics of SHORT. The second subject of study was indoor localisation from hand-held and wearable cameras. For this topic, the RSM dataset was constructed, containing more than 90,000 video frames along more than 3 km of indoor journeys. An open-source pipeline and evaluation is also contributed in this area. The methods include a selection of custom-created single-frame and spatio-temporal image description methods. These are tested against baseline appearance-based methods such as SIFT and HOG3D and state-of-the-art SLAM. Results show that appearance-based methods, even in the absence of tracking, can provide enough information to infer location with errors as small as 1.5 m over a 50 m journey. From the methods studied, results suggest that single-frame approaches perform slightly better than spatio-temporal ones. In third place, I have developed a novel biologically inspired model of artificial place cells based on kernel distance metrics of appearance-based methods between query and database images. Localisation performance was also tested against the RSM dataset, achieving errors as low as 1.4 m over a 50 m trajectory and comparing favourably with the state of the art SLAM. Finally, I have prototyped an assistive localisation system using wearable or hand-held visual input and tactile feedback to track the localisation of the user over haptic maps. An evaluation of the quality of the tactile feedback using this approach is also provided.

Magill, Stephen. "Instrumentation Analysis: An Automated Method for Producing Numeric Abstractions of Heap-Manipulating Programs." Research Showcase @ CMU, 2010. http://repository.cmu.edu/dissertations/73.
Full textAbstract:
A number of questions regarding programs involving heap-based data structures can be phrased as questions about numeric properties of those structures. A data structure traversal might terminate if the length of some path is eventually zero or a function to remove n elements from a collection may only be safe if the collection has size at least n.
In this thesis, we develop proof methods for reasoning about the connection between heap-manipulating programs and numeric programs. In addition, we develop an automatic method for producing numeric abstractions of heap-manipulating programs. These numeric abstractions are expressed as simple imperative programs over integer variables and have the feature that if a property holds of the numeric program, then it also holds of the original, heap-manipulating program. This is true for both safety and liveness. The abstraction procedure makes use of a shape analysis based on separation logic and has support for user-defined inductive data structures.
We also discuss a number of applications of this technique. Numeric abstractions, once obtained, can be analyzed with a variety of existing verification tools. Termination provers can be used to reason about termination of the numeric abstraction, and thus termination of the original program. Safety checkers can be used to reason about assertion safety. And bound inference tools can be used to obtain bounds on the values of program variables. With small changes to the program source, bounds analysis also allows the computation of symbolic bounds on memory use and computational complexity.

Full textAbstract:
Teachers’ beliefs have been identified as a barrier to classroom technology integration. School leadership support that reduces or removes integration barriers can assist teachers in the move from traditional teaching beliefs and practices towards successful classroom technology integration. This mixed methods study investigated beliefs of school leaders and teacher participants concerning support factors that affect technology integration from a mid-sized suburban public school system in the southeastern United States. The quantitative phase of this study included 556 school leaders and teachers. The quantitative survey Beliefs about Teaching with Technology (BATT) measured the school leaders and teachers’ beliefs concerning support factors that affect technology integration. A MANOVA was used to identify significant differences between the two groups and to select the extreme cases for the second phase of the study. An extreme case was defined as one in which the school leaders and teachers had a statistically different view of the beliefs about teaching with technology. Significance was found at the p = .001 level in all categories of beliefs investigated. This qualitative phase of the study included participants from three extreme case schools. Interviews with key informants further explored the differences in beliefs between three leaders and nine teachers and identified differing perspectives between their beliefs about factors that support technology integration in their schools. These interviews also provided descriptions of behaviors related to individuals’ beliefs about these factors. The constant comparative model was used for interview analysis. If classroom technology integration is to be successful, leaders and teachers in a school should possess similar beliefs about the availability and nature of the school-based support, resources, professional development, vision, and incentives necessary to encourage change within a school environment. This study identified the existence of differences in such beliefs between these two groups in one school system, a necessary step before conducting further research on the impact these differences in beliefs could have on individuals’ behaviors related to the successful integration of technology into classroom instruction.

Full textAbstract:
The process and outcome of psychoanalytic psychotherapy have been studied for a long time. However, the experiences of patients, particularly in therapies where goals were not met, have not yet been the target of extensive research. Psychoanalytic psychotherapy with young adults might face particular challenges. The overall aim of this thesis was to explore the experiences of young adults in psychoanalytic psychotherapy, with a particular focus on differences between suboptimal therapies and therapies with generally good outcome. The setting was naturalistic, and perspectives of the patient, therapist and observer were combined. Qualitative and quantitative methods were used. Study I explored experiences of psychotherapy process and outcome among seven patients in psychoanalytic psychotherapy, who expressed dissatisfaction. Interviews at termination and 18 months later were analysed using grounded theory and compared to therapist experiences. Patients experienced abandonment with their problems in and after therapy, since therapy according to the patients lacked connections to daily life, as well as flexibility, activity and understanding from the therapist. Therapists presented a different picture of the same therapies, mainly focused on the difficulties of the patients. Study II analysed the experiences of 20 non-improved or deteriorated young adult psychotherapy patients at termination of therapy and 36 months later. Non-improvement and deterioration were calculated based on the reliable change index on self-rating scores. The grounded theory analysis of interviews established spinning one’s wheels as a core category. The relationship to the therapist was described as artificial, although at times helpful. Participants experienced their own activity in life and active components of therapy as helpful, but thought focus in therapy was too much on past experiences. Study III explored the experiences of 17 young adult patients, in psychoanalytic individual or group therapy, overcoming depression. The analysis of interviews from therapy termination and 18 months later indicated that finding an identity and a place in life were perceived as intertwined with symptom relief. Negative experiences included difficulties to change oneself, fear of change, and problems in therapy, such as too little activity on the therapist’s part. The results were discussed in relation to young adulthood, therapeutic alliance, mentalization, and attachment. The conclusion was expressed in a comprehensive process model of suboptimal therapy with young adults, with suggested ways to prevent such a development. The therapist’s meta-communication and correct assessment of the patient’s mentalization capacity from moment to moment are proposed as crucial. Regarding clinical implications, therapists of young adult patients need to establish meta-communication on therapy progress, as even experienced therapists might be unaware of dissatisfaction or deterioration. Meta-communication could be considered part of the treatment itself, as it may foster mentalization and good outcome. Further, the period of young adulthood entails decisions and developing an adult life, and therapists need to make room for this by active interventions.

Det övergripande syftet med föreliggande uppsats har varit att bidra till en djupare förståelse om självhjälp på Internet genom att belysa individens medvetande och interaktion med andra. Studiens forskningsobjekt har utgjorts av sju individers livsberättelser som återfinns på ett diskussionsforum på Internet och har genomförts enligt en narrativ forskningsmetod och hermeneutiskt ansats. Studien är av kvalitativ art och individens handlande och självupplevda verklighet har stått i fokus. Teorin som applicerats i studien är det pragmatiska mikroperspektivet, symbolisk interaktionism, med följande teoretiska utgångspunkter: symboler, bortträngning, identitetsberövande och ömsesidigt stöd. Analysen är tematiserad enligt studiens tre frågeställningar. I det första temat framgår att bortträngning och identitetsberövande utgjorde två centrala teman i livsberättelserna. Det andra temat behandlade betydelsen av grupptillhörighet, där det tydligt framkommer att diskussionsforumet betyder mycket för stärkandet av informanternas personliga identitet. Det tredje temat visade att förändringar i levnadssätt och levnadsvanor har visat sig i både psykiska och fysiska avseenden. Slutligen diskuteras huruvida en kombination av professionell hjälp som exempelvis terapi och diskussionsgruppen som komplement vore ett bra förfarringssätt att nå den känslomässiga separation, som ännu inte uppnåtts efter den rumsliga separationen som många informanter gjort från sina föräldrar.The overall aim of this essay has been to contribute to a deeper understanding of self-help on the Internet by illuminating the individual's awareness and interaction with others. The study's subject of research has been seven individual life stories found on a newsgroup on the Internet and was implemented with a narrative research method and a hermeneutic approach. The study is qualitative in its nature and the individual's behavior and self-perceived reality has been the main focus. The theory that has been applied in the study is the pragmatic micro perspective symbolic interactionism with the following theoretical starting points: symbols, displacement, deprived of identity and mutual aid. The thematic structure of the analysis has been based on the study’s three research questions of which the first theme highlighted displacement and deprived of identity as the two main themes in the life stories. The second theme dealt with the importance of group membership, which clearly showed that the newsgroup means a great deal for strengthening their personal identity. The third theme revealed that the changes in lifestyle and habits have been both psychological and physical. Whether or not the spatial separation many informants made from their parents can measure up to an emotional separation that they have not yet reached were discussed and lastly an implication that a combination of professional help such as therapy and newsgroup as a supplement may be a good method to reach the emotional separation.

Full textAbstract:
Dependency problems for developers are like sneezing for people with pollen allergies during the spring, an everyday problem. This is especially true when working in multi-repositories. The dependency problems that occur do so as a byproduct of enabling developers to work on different components of a project in smaller teams, where everything is version controlled.Nearly all developers use version control systems, such as Git, Mercurial, or Subversion. While version control systems have helped developers for nearly 40 years and are constantly getting updated, there are still functionalities that do not exist. One example of that is having a good way of managing dependencies and allowing developers to download projects without having to handle dependency problems manually. The solutions that version control systems offer to help manage dependencies (e.g., Git’s submodules or Mercurial’s subrepositories), do not enable developers a fail-safe download or build the project if it contains dependency problems.In this study, a case study was conducted at Saab Training and Simulation to explore methods for dependency management as well as discuss and highlight some of the problems that emerge when working with dependencies in multi-repositories.An argument can be made that the functionality of dependency management systems, both package managers and version control systems’ solutions are not up to date on how dependencies are used in the development, during this time.In this paper, a novel approach to dependency management is introduced with the possibility to describe the dependencies dynamically by providing the utility to describes usages of a repository (such as simulation of hardware or the main project). As well as discussing the necessary functionalities that are required to handle such a system.By re-opening the dialog about dependency management as well as describing problems that arise in such environments, the goal is to inspire further research within these areas.

Full textAbstract:
Syftet med studien var att undersöka socialsekreterares erfarenheter av att neka ekonomiskt bistånd. Tre frågeställningar formulerades: Hur påverkas socialsekreterare känslomässigt av att neka ekonomiskt bistånd? Hur upplever socialsekreterarna att klienterna reagerar i samband med ett avslag? Finns det andra faktorer som påverkar socialsekreterarnas erfarenheter av att ge avslag? Fem intervjuer genomfördes med socialsekreterare på fyra olika kommuner i Skåne. Resultatet visade att ett avslagsbeslut inte påverkade socialsekreteraren negativt i någon större utsträckning. Även om majoriteten av informanterna uttryckte att det ibland kunde kännas jobbigt att ge ett avslag fanns det coping- strategier och arbetssätt som underlättade i arbetet med avslag. En känsla av sammanhang (KASAM) kunde identifieras som en underlättande faktor. Klienterna kunde ibland bli arga och inte förstå beslutet men de kunde också bli mer motiverade. Faktorer som ramlag, kollegor och yrkeskunskap spelade stor i arbetet. Att ha en tydligt distans till klienten, tilltro till klientens förmåga att förändra sin situation och att det är individen som har ansvar för sin situation underlättade i arbetet med avslag. Ett avslag kan således betyda mer än bara ett ”nej, du har inte rätt till bistånd.”The aim of this study was to look into social workers experiences on rejecting financial assistance. Three questions were to be answered: In what way are the social workers emotionally affected by rejecting financial assistance? How do the social workers experience the clients reactions when getting a rejection on financial assistance? Are there any other factors affecting the social workers experiences on rejecting financial assistance? Five interviews were conducted with social workers from five different municipalities in Skåne, Sweden. The result showed that rejecting financial assistance did not affect the social workers negatively in a significant manor. Even though the majority of the informants sometimes expressed some level of awkwardness while rejecting finical assistance, there were coping strategies and methods that favored the rejection process. Clients could sometimes become angry, not understanding why the application was rejected but they could also become more motivated. Factors like framework, colleagues and knowledge of the profession played a big part in the daily work. A sense of coherence was also found to be a stress relieving factor. The rejection process was made easier by having a clear emotional distance to the client, a faith in the clients own abilities to change hir situation and also knowing that it is the individual that has full responsibility of hir situation. A rejection can therefore be viewed as something more than just ”no, you’re not entitled the right to receive financial assistance.”

West, Bryan A. "Conceptions of geographic information systems (GIS) held by senior geography students in Queensland." Queensland University of Technology, 2008. http://eprints.qut.edu.au/16682/.
Full textAbstract:
Geographical Information Systems (GIS) represent one of the major contributions to spatial analysis and planning of the new technologies. While teachers and others have viewed its potential contribution to geographical education as considerable, it has not been known with any certainty whether they present a valuable educational tool that aids geographical education. The value of GIS to geographical education is viewed as depending on a geographical education being, in itself, valuable. Within this context, synergetic focus groups are employed to explore the conceptions of GIS held by 109 secondary school students studying Senior Geography in metropolitan and regional Queensland, Australia. A phenomenographic approach is adopted to identify the six qualitatively different ways, or conceptions, in which the participating students experience GIS as: 1. Maps and a source of maps in geography. 2. Mapping in geography: a way to use and create maps. 3. A professional mapping tool: exceeding the needs of senior geography. 4. Frustrating geography: irksome and presenting many challenges to the student-user. 5. Relevant geography: within and beyond the school experience. 6. A better geography: offering a superior curriculum, and broader geographical education, when contrasted to a senior geography that omits its use. The structural and referential elements of each of these conceptions are elucidated within corresponding Categories of Description. The qualitatively different ways in which the conceptions may be experienced are illustrated through an Outcome Space, comprising a metaphoric island landscape. This structural framework reveals that for the Senior Geography students who participated in this investigation, the extent to which GIS may augment the curriculum is influenced by the nature of students' individual understandings of how GIS manages spatial data. This research project is a response to repeated calls in the literature for teachers of geography themselves to become researchers and for a better understanding of GIS within geography education. It reviews the salient literature with respect to geography and geography education generally, and GIS within geographical education specifically. The investigation has confirmed that qualitatively different conceptions of GIS exist amongst students and that these are not consistently aligned with assumptions about its use and benefits as presented by current literature. The findings of the study contribute to knowledge of the potential educational outcomes associated with the use of GIS in geography education and decisions related to current and potential geography curricula. It provides guidance for future curriculum development involving GIS and argues for additional research to inform educators and the spatial sciences industry about the actual and perceived role of GIS within geography education.

Full textAbstract:
Syftet med föreliggande studie var att undersöka hur ryttare upplever Flow, och vidare även hur ryttare upplever samspelet inom ekipaget vid Flow. Studien inkluderade 10 kvinnliga informanter (M = 18.7, SD = 1.48) med tävlingserfarenhet som sträcker sig från ingen alls till internationell nivå (Hoppning= 4, Dressyr = 3, Fälttävlan = 2, Ingen tävling = 1). En semi-strukturerad intervjuguide utvecklades utifrån Csikszentmihalyi's holistiska perspektiv på de nio dimensionerna av Flow (Jackson & Csikszentmihalyi, 1999), och data analyserades kvalitativt genom en innehållsanalys. Resultatet visade både att ryttares upplevelse av Flow stämmer väl överens med andra idrottsutövares upplevelse (Swann, Keegan, Piggott och Crust, 2012), och bekräftar tidigare tolkningar av att ridsporten skiljer sig från de flesta andra idrotter genom att utfallet till stor del är beroende av interaktionen och samarbetet mellan häst och ryttare (Beauchamp & Whinton, 2005). Vidare visar resultatet även att samspelet mellan häst och ryttare är en viktig och oersättlig del i upplevelsen av Flow.Theaim of this study was to investigate how riders perceive Flow, and how ridersperceive the interactions with the horse during Flow. The study included 10female respondents (M = 18.7, SD = 1.48) with competition experience rangingfrom none at all to international level (Jumping = 4, Dressage = 3, Eventing =2, No competition = 1). A semi-structured interview guide was developed basedon Csikszentmihalyi's holistic perspective on the nine dimensions of Flow(Jackson & Csikszentmihalyi, 1999), and data were analyzed throughqualitative content analysis. The results showed both that the riders'experience of Flow correspond well with other athletes experience (Swann etal., 2012) and confirms earlier interpretations of that riding is differentfrom most other sports though the outcome largely depends on the interactionand collaboration between horse and rider (Beauchamp and Whinton, 2005).Furthermore, the results also show that the interaction between horse and rideris an important and irreplaceable part in the experience of Flow.

Full textAbstract:
The present study aimed to explore the culture specificity of student self-regulation and its supporting motivational attitudes. Specifically, it enquired about similarities and differences between Chilean and English 8 to 9 year-old students in terms of their expression of self-regulatory behaviours, the psychological factors underlying these behaviours, and the functionality of these behaviours for task performance. It also compared student adoption of achievement motivational attitudes as well as the functionality of these attitudes for investment of effort and self-regulatory activity between cultures. Finally, the role of classroom cultures for self-regulation was studied. In particular, it examined the effects of classrooms and the quality of teacher talk (teacher-to-student communicative interactions/demands), such as teacher ‘regulatory talk’ and ‘socio-motivational talk’, on student self-regulation. A quantitative approach to the analysis of qualitative data (i.e. videos of student behaviour engaged in 11 to 13 experimental tasks, semi-structured interviews, videoed literacy lessons) was adopted. Eight classrooms situated in different schools from Chile and England were part of the study. In total, 8 teachers and 49 students – one teacher and six to seven students per classroom – took active part in the study. Qualitative data was primarily analysed using observational scales (for student behaviour), thematic analysis (for interview data), as well as socio-cultural discourse analysis (for videoed lessons). Statistical techniques, such as Mann Whitney U test, Factor Analysis, Multinomial logistic regressions, and Multilevel regressions were then applied on numerical transformations of the data. Overall, results suggest that self-regulation and achievement motivational attitudes vary to important extents according to culture. Most interestingly, these varied between cultures not so much in terms of the degree to which children used or adopted them, but rather in terms of their functionality. Some key findings supporting this conclusion were: i) Strong similarities between English and Chilean children’s levels of self-regulatory behaviours; ii) substantial differences across country samples in relation to the psychological factors underlying the expression of specific self-regulatory behaviours; iii) the finding of evaluative actions being self-regulatory in England but not in Chile; iv) a higher variety of self-regulatory behaviours being predictive of task performance in England than in Chile; v) the fact that learned self-regulatory behaviours accounted for effects of effective metacognitive control on task performance in England but not Chile; vi) some important differences in the achievement motivational attitudes expressed by Chilean and English students; and vii) culture-specific functionalities of various achievement motivational attitudes with respect to student effort and self-regulatory behaviours. Moreover, results suggest that some aspects of children’s self-regulation and motivational attitudes develop as tools to adapt to classroom cultures, specifically to the learning interactions/demands socially afforded by teacher talk. Among key findings supporting this conclusion were: i) effects of classrooms on children’s cognitive, social, and motivational self-regulation behavioural strategies, and ii) clear effects of teacher ‘regulatory talk’ (e.g., teacher ‘self-regulatory talk’ predicting more planning and asking for clarifications in students) and ‘socio-motivational talk’ (e.g., teacher ‘talk against self-efficacy’ predicting higher dependency-oriented help-seeking in students) on those behaviours with respect to which classrooms were found to matter. Thus a theory about the culturally adaptive functionality (CAF) of self-regulation and motivational attitudes supporting self-regulation is developed throughout the thesis.

Full textAbstract:
Uppsatsens syfte var att undersöka processen för hur socionomers professionella yrkesidentitet framträder. Hur identiteten utvecklas i förhållande till professionen, utvecklingen från student och i övergången till yrkeslivet. En narrativ intervjustudie har genomförts där fyra socionomer intervjuats, två socionomstudenter och två yrkesverksamma socionomer. Intervjuerna har sammanställts till narrativ. Det teoretiska ramverket som används är socialkonstruktivistiskt perspektiv, det framträdande jaget och begreppet professionell identitet. Tidigare forskning visar att utvecklingen av den professionella identiteten påbörjas innan utbildningen där utvecklingen fortsätter, det viktigaste inslaget anses vara praktiken. Socionomen har ett brett arbetsfält och den professionella identitetens utveckling har en stark påverkan av kollegor och lagar. Resultatet överensstämmer till stor del med tidigare forskning men visar också på en påverkan av samhällets uppfattning om socionomer. Under studierna skapas en förståelse för den professionella identiteten, den verksamhetsförlagda utbildningen ger studenten tillfälle att testa sin professionella identitet. Tidigare yrkeserfarenhet tolkas ha en roll i förståelsen av professionell identitet och skillnad mellan privat och professionell. I början av yrkeslivet görs en tydlig skillnad mellan professionell och privat identitet men med tiden flyter dessa ihop. De professionella understryker en stark påverkan av lagar och egenskaper som inte förenas med den privata identiteten. Socionomers professionella identitet är en oändlig process.The purpose of this study was to examine the process of social workers professional identity emerges and its development from education to profession. Narrative interviews were conducted with four informants, two students and two social workers. Tools for analyzing the narratives and the identities are the term professional identity and narrative perspectives which are represented by the social constructivist perspective and prominent self.Previous research shows that the development of the professional identity can begin before and within the education. In the professional life, development of the professional identity has a strong influence dependent on colleagues and laws. The results are largely in line with previous research but also underline an impact on society's perceptions of social workers. During the studies, an understanding is created of the professional identity that students test in their internship. Previous professional experience is interpreted to have a role in understanding professional identity and the difference between private and professional. At the beginning of career, a clear distinction is made between professional and private identity, but over time, these also merge. The professionals emphasize a strong influence of laws that are not associated with private identity. Social workers professional identity is a never-ending process.

Full textAbstract:
Thesis (PhD)--University of Stellenbosch, 2004.ENGLISH ABSTRACT: This study investigated the impact that use of a microcomputer-based laboratory (MBL), in this case the TRAC PAC and associated software, had on student understanding in relation to common 'alternative learner ideas' and difficulties related to kinematics and kinematic graphs. It was carried out in the South African context, and focussed on subject matter that learners are expected to work with in preparation for the Senior Certificate South African examination. Twenty Grade 12 learners from four different schools participated in the study. Three key questions were investigated: 1. What conceptual difficulties do learners in this context experience in relation to kinematics and kinematic graphs? 2. Does use of the TRAC PAC as a microcomputer-based laboratory contribute to learner understanding of graphs of motion and related concepts? 3. If learning is enhanced using the TRAC PAC, what are some of the 'ways of learning' evident as learners participated in the MBL programme? To answer these questions, the study employed both an empirical quantitative dimension and an ethnographic qualitative dimension. The empirical study involved the use of pre- and post-questionnaires which were administered before and after learners participated in a TRAC PACbased learning programme comprising of six 3-hour learning activities conducted over three days. Overall learner performance on the questionnaires, as well as responses to individual questions, were analysed statistically, as well as through use of an 'item and matrix' analysis technique described by Svec (1999). Chapter 8 of this document reports on this component of the study. The ethnographic component of the study made use of observational data, and transcripts of video and audio recordings of learners as they participated in the learning activities. The data gathered using these techniques was analysed largely through use of a 'verbal analysis' technique described by Chi (1997). Chapter 9 of this document reports on this component of the study. In relation to Research Question 1, the main findings of the study were: • A literature review highlighted common 'alternative learner ideas' identified by other researchers, and these allowed me to group them into four main areas. These are described in Chapter 4 of this report. • The analysis of the questionnaires highlighted 'alternative learner ideas' that the group of learners who participated in this project held. These are described in Chapter 8 of this report. • The analysis of the video and audio transcripts also allowed for the identification of 'alternative learner ideas' held by this group of learners. These are described in Chapter 9 of this report. There was a high degree of commonality between the 'alternative learner ideas' identified through use of these three different sources. Research Question 2 was answered mainly through the empirical study described in Chapter 8 of this report. It was found that the MBL experience generally resulted in an improvement in learner understanding in this area of kinematics and kinematic graphs. More detailed statistical and 'item and matrix' analyses showed that the impact on learner understanding was better in certain areas than in others. The ethnographic study described in Chapter 9 contributed to answeri The degree of learner involvement in learning activities seemed to impact on the effectiveness of the programme. Possible factors impacting on involvement were identified . • 'Alternative learner ideas' were made visible in the context of 'argumentation episodes' and 'discussion and explanation episodes'. Consequently, these formed the contexts in which shifts in understanding were most likely to take place. Key learner behaviours and skills necessary for participation in these episodes are identified, and linked to success and non-success on the programme. Recommendations arrsmg from findings m the study are described m Chapters 8, 9 and 10of this report.
AFRIKAANSE OPSOMMING: Hierdie ondersoek bestudeer gebaseerde laboratorium, III gepaardgaande sagteware, op kinematikagrafieke het. die uitwerking wat 'n hierdie geval die TRAC studente se begrip van mikro-rekenaar PAC en die kinematika en Die ondersoek is III 'n Suid-Afrikaanse konteks uitgevoer en is toegespits op die vakmateriaal wat leerders behoort te beheers ter voorbereiding vir die Suid-Afrikaanse Senior Sertifikaat. Twintig Graad 12' s van vier verskillende skole het aan die ondersoek deelgeneem. Drie sleutelvrae is ondersoek: 1. Watter begripsprobleme ondervind leerders in hierdie verband met betrekking tot kinematika en kinematikagrafieke? 2. Dra die gebruik van die TRAC PAC as 'n mikro-rekenaar gebaseerde laboratorium by tot die leerder se begrip van kinematikagrafieke en verwante begrippe? 3. Indien "leer" deur die gebruik van die TRAC PAC bevorder word, watter "vorme van leer" is waarneembaar as leerders deelneem aan die MBL-program? Beide 'n empiries-kwantitatiewe dimensie en 'n etnografiese kwalitatiewe dimensie is in die navorsing gebruik. Die empiriese ondersoek maak van beide 'n voortoets en 'n na-toets gebruik. Hierdie vrae is aan die leerders voorsien voordat asook nadat hulle aan die TRAC PAC gebaseerde leerprogram deelgeneem het. Die leerprogram het bestaan uit ses leeraktiwiteite, elk drie uur lank, wat oor 'n tydperk van drie dae gedoen is. Die leerders se prestasie/uitslae met betrekking tot die vrae asook hul reaksie op individuele vrae is statisties ontleed, asook met behulp van die 'item en matriks' analitiese tegniek soos deur Svec (1999) beskryf. Hoofstuk 8 van hierdie verslag verwys na hierdie deel van die ondersoek. Die etnografiese komponent van die die ondersoek maak gebruik van waarnemingsdata en transkripsies van band- en video-opnames van leerders verkry tydens hul deelname aan die leeraktiwiteite. Die data so verkry, IS hoofsaaklik geanaliseer deur van die 'n verbale analise-tegniek gebruik te maak soos deur Chi (1999) voorgestel. Hoofstuk 9 van hierdie dokument doen verslag oor hierdie komponent van die ondersoek. Wat Navorsingsvraag 1 betref, IS die hoofbevindings van die studie die volgende: • 'n literatuur-oorsig beklemtoon die algemene alternatiewe leerderopvattings wat deur ander navorsers geidentifiseer is. Dit het my in staat gestelom hulle in 4 hoofareas te groepeer wat ek in hoofstuk 4 van die verslag bespreek. • Die analise van die vraelyste beklemtoon die alternatiewe leerderopvattings van die groep leerders wat aan hierdie proj ek deelgeneem het. Dit word in hoofstuk 8 van hierdie verslag bespreek. • Die analise van die band- en video-opnames het ook bygedra tot die identifikasie van' alternatiewe leerder-idees' wat by hierdie groep leerders voorkom. Dit word in hoofstuk 9 van hierdie verslag bespreek. Daar is 'n groot mate van ooreenkoms ten opsigte van die alternatiewe leerderopvattings wat by hierdie drie verskillende groepe voorkom. Navorsingsvraag 2 is hoofsaaklik beantwoord deur die emprrrese studie wat in hoofstuk 8 van hierdie verslag bespreek word. Daar is bevind dat die MBLondervinding oor die algemeen 'n vebetering in die leerders se begrip ten opsigte van kinematika en kinematikagrafieke tot gevolg gehad het. 'n Meer gedetailleerde statistiese 'item en matriks' -analise het getoon dat die uitwerking op die leerders se begrip in sommige areas beter was as in ander. Die etnografiese studie wat in hoofstuk 9 van hierdie verslag beskryf word, dra by tot die beantwoording van Navorsingsvraag 3. Sleutelbevindings met betrekking tot hierdie vraag sluit onder andere in: • Leerderdeelname aan leeraktiwiteite hou skynbaar verband met die sukses wat hulle in die program behaal. Moontlike faktore wat 'n invloed op deelname kon hê, is geidentifiseer. • Alternatiewe leerderopvattings is In die konteks van 'beredeneringsepisodes ' en 'besprekings- en verduidelikings-episodes' uitgelig. Hierdie "episodes" het die waarskynlikste verband uitgewys waarbinne veranderings van insig/begrip kan plaasvind. Kernleerdergedrag en vaardighede wat noodsaaklik IS vir die deelname aan hierdie episodes is geidentifiseer, en is gekoppel aan 'n leerder se sukses en mislukking tydens deelname aan die program. Aanbevelings wat voortspruit uit die bevindings van die ondersoek word In hoofstukke 8, 9 en 10 van hierdie verslag, bespreek.

Full textAbstract:
Für die Trassierung von Straßenverkehrsanlagen hat sich neben anderen Methoden die Verwendung von Biegelinealen als vorteilhaft erwiesen und vor über 50 Jahren etabliert. Inzwischen hat der Einsatz moderner Entwurfssoftware in den Straßenbauverwaltungen und Planungsbüros das Biegelineal trotz seiner Vorteile aus der Praxis verdrängt. Keines der Entwurfsprogramme legt das strukturmechanische Prinzip des Biegelineals zugrunde, da die Verformungen des zu Trassierungszwecken ausgelegten Biegelineals nicht exakt berechnet werden können.
An diesem Punkt setzt die vorliegende Arbeit an, sie umgeht das Problem auf numerischem Wege unter Anwendung der Finiten Elemente Methode (FEM). So lassen sich über Strukturanalysen die Verformungen einer um seine Hauptträgheitsachsen punktuell ausgelenkten, prismatischen Balkenstruktur mit doppeltsymmetrischem Querschnitt berechnen. Mit der Analyseantwort ergeben sich insbesondere die dreidimensionalen Koordinaten einer Punktfolge, welche die Biegelinie quasiexakt repräsentiert. Die dreidimensionale Biegelinie setzt sich aus einer Achse und einer Gradiente zusammen und ist im Rahmen der Vorplanung geeignet, eine richtliniengerechte Straßenverkehrsanlage zu erzeugen.
Das Untersuchungsergebnis stellt eine neuartige Grundlage für ein dreidimensionales Trassierungsverfahren dar, bei dem ein mathematisch modelliertes Biegelineal im Digitalen Geländemodell (DGM) verformt wird.
