System dynamics was founded in 1956 by Professor Jay W. Forrester from the Sloan School of Management, Massachusetts Institute of Technology. Forrester mentioned the¡uLevel equation is also known as a first-order differential equation in the branch of mathematics¡K¡K¡v in the book of Principles of Systems. Hence fundamentally system dynamics is a dynamic model in the mathematical model itself, which can also be expressed as a differential equation model. Since the 17th century, differential equation has evolved to become a powerful tool for analyzing the natural processes, and it has developed several research and observation methods, such as the resolution analysis, qualitative analysis and numerical analysis. System dynamics can be applied to solve those kind of problems about high-order, nonlinear, time delay and causal feedback, and these problems are difficult to transform into mathematical models. However, researchers have already addressed many modeling approaches using the basis of system dynamics. In this study, a new transformation method is studied using system dynamics model and transforms it into differential equation model with the aid of mathematical software, applying qualitative analysis and numerical analysis to observe and analyze the differential equation model in order to understand the structure and behavior of the system dynamics model.

<p>ADHD är en vanligt förekommande neuropsykiatrisk störning bland barn, vilka uppvisar beteende som överaktivitet, uppmärksamhetsstörning och impulsivitet. För föräldrarna kan detta innebära svårigheter att hantera barnens beteende och sätta begränsningar. Syftet med studien var att belysa föräldrars upplevelse från sitt dagliga liv med barn med ADHD problematik. Metoden som använts var en litteraturstudie som analyserades med kvalitativ innehållsanalys och baseras på sju vetenskapliga artiklar som motsvarade syftet för studien. I resultatet framkom: Föräldrarnas uppfostringsförsök, Föräldrarnas relation, Ett minskat kontaktnät, Behov av stöd och hjälp, Hopp och förtvivlan samt Kulturkrock och rollförväntningar. Det förekom i resultatet att föräldrarna hade ett svårthanterbart liv som berodde på barnets problematik. Många föräldrar hade svårighet att acceptera barnets diagnos, vilket gav upphov till blandade känslor som sorg, frustration, ångest, lidande men även välbefinnande. Barnets överaktivitet och impulsivitet hade en stor inverkan på föräldrarnas liv. Föräldrarna lärde sig olika tillvägagångssätt för att hantera barnets beteende. Resultatet visade också att föräldrarna upplevde en stor förändring av sitt sociala liv vilket innebar ett minskat kontaktnät för föräldrarna. Att ha barn med ADHD var påfrestande och föräldrarna upplevde sig jämt missförstådda och hjälplösa, men trots det accepterade de flesta föräldrar sin situation och gjorde det bästa av det.</p>

Social networking has become integrated into every aspect of business that one can imagine and universities must take advantage of the phenomenon to build personal relationships with young alumni in an effort to build a lifetime of loyalty. This study addresses some issues that should be considered to build loyalty in young alumni, from the moment of their first arrival, rather than waiting until after they graduate to cultivate them. This study examines how alumni relations officers can help build relationships through social networks, and in-school interventions that will help creating lifetime loyalty among young alumni. Young alumni, who are more familiar with technology than older generations of alumni are a prime target audience that should be considered to study efficient and effective way for universities to get their messages out. Through an interactive qualitative analysis study, this research addresses the factors that keep alumni from wanting to hear about and be vested in their alma mater before they graduate and how they will communicate with the university after graduation. This study explores the broad question, Why do some students use alumni social media and some do not? To answer the question, the researcher explores the phenomenon of The Undergraduate Experience and Using Social Media. Using Interactive Qualitative Analysis (IQA), this study identifies the elements that make up The Undergraduate Experience and The Using Social Media Experience. The study goes further by identifying how these elements relate in a system of influence. The study concludes with practical solutions for the engagement of alumni. / text

One key goal of Physics Education Research is providing research-based instructional techniques and tools to help assess the complex learning goals associated with a mature understanding of physics. Characterizing faculty expectations is important to produce a comprehensive understanding of knowledge students should acquire before and during a quantum mechanics course (QMC). Semi-structured interviews have been conducted with faculty members and students entering a QMC in the Physics Program at a Large Public Research University (LPRU) in the Southeast. The interviews examine perspectives of different evaluation techniques, ideal preparation, course content, and expected conceptual models of students. A post-course survey was offered to the students that took the QMC in the Fall of 2012 and to those who completed the course in the past three years. The survey addressed similar questions on evaluation, course content, and preparation. Using Classical Content Analysis and Key-Words-In-Context coding methods, contradictions and similarities within and between faculty and student populations are presented. These results are presented in an effort to highlight predictors for success in the QMC, identify “common-core” perceptions, and strengthen course evaluation. In all data, findings suggest that student perceptions shift towards those of faculty over the course of the QMC. Evaluation data indicate that on average the faculty members, like students, are open to a varied array of evaluation techniques, if it is within the goals of the course and does not interfere with other faculty responsibilities. In perceptions of preparation and course content, faculty have a uniform perspective of what should be prerequisite, and the student survey data strongly recommend that the second semester of Linear Algebra offered at the LPRU will help with the mathematical complexities of the QMC. Through triangulation of qualitative and quantitative results contradictions of preparation and content are exhibited through multiple media for the use course content such as the Hamiltonian.

The primary purpose of this study was to develop a two-tier multiple choice diagnostic instrument to assess Singapore Grade 10 students' (15 to 17 years old) understanding and alternative conceptions of qualitative analysis. Additional and related purposes were to determine whether more advanced chemistry students, for example, junior college (Grade 11 and 12) students, undergraduates and graduate trainee-teachers have a better understanding of basic qualitative analysis than secondary students, and to develop appropriate teaching strategies and materials on qualitative analysis based on the findings of this study and a review of the literature on practical work.The results from the administration of the diagnostic instrument showed that Singapore Grade 10 students had many alternative conceptions related to qualitative analysis, and these were grouped under the headings of 'Displacement', 'Redox', 'Dissolution', 'Addition of acid' and 'Heating'. The cross-age study showed that the more advanced chemistry students generally had a better understanding of basic qualitative analysis but had similar alternative conceptions as the Grade 10 students. However, the alternative conceptions identified were consistently held by only a small number of students across all contexts examined in the diagnostic instrument, suggesting that a number of students either had more than one conception for a particular concept or no conceptions at all. The results from the trial of the qualitative analysis teaching package indicated that the teaching package was feasible. Teachers involved in the trial found it structured and comprehensive, and the students who experienced the teaching package performed better on the diagnostic instrument than a comparison group.The study recommends that better ways of conducting qualitative analysis practical work are required, and using the teaching ++ / package may be a step in this direction. The study also raises questions about the value of teaching qualitative analysis in secondary schools when important reactions involved in qualitative analysis are omitted from the syllabus, and when there is little incentive and time in the school curriculum for learners to understand what they are doing in qualitative analysis.

Mona Wilhelmsson Göstas, School of Health and Medical Sciences, Örebro University, SE-701 82 Örebro, Sweden, mona.vilhelmsson gostas@orebroll.se Attachment styles are relevant to psychotherapy since they highlight the way a person handles interpersonal and emotional stress. This thesis aimed to examine how psychotherapy patients in the public mental health care system report attachment styles related to interpersonal problems and diagnosis before and after psychotherapy and to examine problems and changes and psychotherapy contract and process from patients’ experiences of cognitive behavioural oriented therapy (CBT) and psychodynamic oriented psychotherapy (PDT). The studies are based on data from patients admitted to psychotherapy within the public psychiatric services in Örebro County Council. Studies I and IV were quantitative and used self-reports to examine attachment styles and interpersonal problems before and after psychotherapy. Studies II and III were qualitative interview studies examining patients experiences of problems, changes and psychotherapy process. The patients were diagnosed with mood disorders, anxiety disorders, adjustment disorders and personality disorders and reported insecure avoidant and anxious attachment styles that correlated positively with interpersonal problems when they started therapy. Psychotherapy with CBT or PDT enabled them to turn attachment styles into more secure ones and decrease interpersonal problems Patients aged between 26 and 39, patients who attended 11-25 sessions and patients diagnosed with a personality disorder reported greater changes in secure related attachment than others. Patients described their problems as emotions that could not be regulated, as cognitive disabilities and as problematic behaviours that implied a self-centredness. During the course of psychotherapy, the patients gained abilities to handle their problems. The perceived self-centeredness changed which increased their participation in their life-context. Similarities across the therapy orientations showed that the creation of a new context was essential to pay full attention to the patient’s problems, and that the working method and cooperation with the psychotherapist made up a whole. To make the therapy effective, it is important to build up confidence in cooperation and secure base functions like offering predictability and shaping interventions according to the needs of the patient and their ability to use them.

Introduction Maternal mental health during pregnancy and its effects on offspring outcomes have received increased attention as a public health concern. Recent policies have highlighted the need for better universal perinatal services and to routinely incorporate attention to mental health into antenatal care. This thesis aimed to examine and evaluate current research into the effects of maternal antenatal depression on child psychological, development and developmental psychopathology. A research study was carried out with the aim of understanding the subjective experiences of women with antenatal depression during pregnancy and their transition to motherhood. Method Quantitative studies, exploring the relationship between antenatal depression and early child development were reviewed systematically. The empirical study employed Interpretative Phenomenological Analysis to investigate the experience of antenatal depression in pregnant women. Semi-structured interviews were conducted with six participants who were pregnant and recruited from a perinatal mental health service. Results The small number of papers considered suitable for this review highlights the lack of good quality research in this field. Twelve studies met inclusion criteria for the systematic review, demonstrating mixed results regarding whether antenatal depression effects early child development. Studies were predominantly of poor methodological quality, with inconsistent results and limited by the use of differing antenatal depression and infant development outcomes, making cross study comparisons difficult and weakening any conclusions that could be drawn. In the empirical study one super-ordinate theme, ‘The Lost Self’, and four main themes emerged. Conclusions Findings were inconsistent and of poor quality, and so we cannot say for sure whether antenatal depression itself is associated with adverse outcomes for young children. Further rigorous research on antenatal depression and adverse early child outcomes is needed in order to try and disentangle the effects of both antenatal and postnatal depression on each other and on child development. The findings from the empirical study contribute to an increased understanding of the experiences and challenges faced by women experiencing depression during pregnancy. The study highlights the need for improved awareness of depression during pregnancy to improve understanding of this disorder during the antenatal period.

Few policies carry more controversy than voter photo identification requirements. First passed in 2003, these laws require voters to present government-issued ID’s, such as a driver’s license, state identification card, military ID, or qualifying student ID. This paper examines the discursive politics in Wisconsin’s photo ID, seeking to understand how state policymakers justified the law against accusations of voter suppression. Put broadly, this paper seeks to understand the intersection of politics and policy, exploring how irrational policies are formed, implemented, and evaluated.
