Dynamic structural equation modeling (DSEM) is a novel, intensive longitudinal data (ILD) analysis framework. DSEM models intraindividual changes over time on Level 1 and allows the parameters of these processes to vary across individuals on Level 2 using random effects. DSEM merges time series, structural equation, multilevel, and time-varying effects models. Despite the well-known properties of these analysis areas by themselves, it is unclear how their sample size requirements and recommendations transfer to the DSEM framework. This article presents the results of a simulation study that examines the estimation quality of univariate 2-level autoregressive models of order 1, AR(1), using Bayesian analysis in Mplus Version 8. Three features are varied in the simulations: complexity of the model, number of subjects, and number of time points per subject. Samples with many subjects and few time points are shown to perform substantially better than samples with few subjects and many time points. 相似文献

In this paper the current national legislations, the quality assurance approaches and the activities of impact analysis of three quality assurance agencies from Romania, Spain and Germany are described from a strategic perspective. The analysis shows that the general methodologies (comprising, for example, self-evaluation reports, peer reviews, on-site visits, assessment reports, follow-up measures) and main subjects of quality assurance in higher education (such as study programmes and institutional structures and processes) are very similar in the sample cases. However, up to now, impact evaluation of quality assurance has not been implemented systematically in the sample agencies (as in many others). This is the more relevant since the European standards of quality assurance in higher education oblige quality assurance agencies to analyse their general findings and observe the effects of their activities. Against that background, it is argued that methodologically sound impact analyses of quality assurance interventions in higher education institutions should be seen as an integral part of the agencies’ own quality assurance because it would make their work more transparent and easier to improve systematically. The paper identifies some professionalisation needs required for impact evaluation competences: staff and peers who are qualified by methodological knowledge but also by ‘soft’ skills such as project and conflict management. 相似文献

The context of higher education across the world currently presents evidence of university failures. These failures are evident in areas such as governance, financial and risk management, conduct of senior leaders and quality assurance issues surrounding international education. Having this in mind, the present paper argues the need to add a new definition (to what is already known) of quality. The conceptual approach proposed by the authors takes into account ethics and morals as key virtues of the higher education sector. The literature shows that it is still difficult to find agreement on a single definition of the concept. University leaders and quality assurance professionals define quality in many different ways. However, despite the ethical challenges in the current higher education landscape, little has been discussed on the connection between quality, ethics and moral values. Therefore, the authors provide the unexplored relationship between these concepts. 相似文献

OBJECTIVE: This report describes a method for linking separate confidential data sets that contain personal identifying information while preserving required anonymity. METHODS: Research data were linked with child abuse and neglect (CAN) report data by an independent "safe" analyst using an identical set of unique identifier codes assigned to each case in both data sets after all personal identifiers had been removed. RESULTS: The research team never learned CAN report status of individuals, the state agency never saw the research data, and the desired analyses were completed using the merged data set. CONCLUSIONS: The method was successfully used to merge data from separate sources without divulging confidential information. 相似文献

在终身学习领域,成人学习质量保障一直是各国政策中的行动焦点。21世纪以来,欧盟先后出台了有关成人学习质量保障的政策,诸多国家明确了质量保障体系的实施目标、运行流程,制定了较为细化的评估指标体系。其中,设计理念的相关性、体系设计的科学性、运行进程的透明性以及评估主体的多元性推动了欧盟各国成人学习质量保障体系朝正确的方向发展。然而,目前欧盟各国缺乏综合性的质量保障体系、成人学习特殊元素难以彰显、成人学习专业工作者的持续专业发展困境以及缺乏监测信息数据等,桎梏了成人学习质量保障体系的＂更上一层楼＂。基于欧盟国家的实践,无疑拓宽了我国成人学习质量保障体系发展的视野。在整体框架设计原则上,要遵循综合性与特殊性相结合的原则;在操作哲学上,要从＂技术＂转向＂文化＂;在关键元素上,要关注成人学习工作者的专业化;在反馈控制上,要实现质量信息的资源共享。 相似文献

Statistical tools found in the service quality assessment literature—the T2 statistic combined with factor analysis—can enhance the feedback instructors receive from student ratings. T2 examines variability across multiple sets of ratings to isolate individual respondents with aberrant response patterns (i.e., outliers). Analyzing student responses that are outside the “normal” range of responses can identify aspects of the course that cause pockets of students to be dissatisfied. This fresh insight into sources of student dissatisfaction is particularly valuable for instructors willing to make tactical classroom changes that accommodate individual students rather than the traditional approach of using student ratings to develop systemwide changes in course delivery. A case study is presented to demonstrate how the recommended procedure minimizes data overload, allows for valid schoolwide and longitudinal comparisons of correlated survey responses, and helps instructors identify priority areas for instructional improvement. 相似文献

This paper describes how Singapore attempts to balance the need for quality assurance and the need for educational diversity
and innovation. The Singapore experience shows that this is a delicate balance. On the one hand, to promote diversity and
innovation, the government attempts to decentralise its power to the schools. On the other hand, for quality assurance, the
government sets up quality structures that reassert the centrality of government control. This paper examines the implications
of such a strategy and the challenges that schools face in navigating a new paradigm of diversity and innovation while satisfying
the requirements of quality assurance. 相似文献

Recently a new clustering algorithm called ＇affinity propagation＇ （AP） has been proposed, which efficiently clustered sparsely related data by passing messages between data points. However, we want to cluster large scale data where the similarities are not sparse in many cases. This paper presents two variants of AP for grouping large scale data with a dense similarity matrix. The local approach is partition affinity propagation （PAP） and the global method is landmark affinity propagation （LAP）. PAP passes messages in the subsets of data first and then merges them as the number of initial step of iterations; it can effectively reduce the number of iterations of clustering. LAP passes messages between the landmark data points first and then clusters non-landmark data points; it is a large global approximation method to speed up clustering. Experiments are conducted on many datasets, such as random data points, manifold subspaces, images of faces and Chinese calligraphy, and the results demonstrate that the two approaches are feasible and practicable. 相似文献

Studies of student re-enrolment patterns in higher education constitute, along with traditional studies of persistence and dropout, a key element for improving the quality of higher education institutions. However, these studies tend to be limited as they are centred on a single institution, due to the lack of national-scale data sets for monitoring students between different institutions. Using a longitudinal population-based data set provided by the Catalan University Assurance Agency (AQU), which includes information records on 21,473 undergraduate students, this paper aims to develop and test an exploratory model of student re-enrolment, specifically in the Catalan public university system. We are not only interested in student re-enrolment, but also in whether they do so during the first year after dropout or in the same area of knowledge. Results from logistic regression analysis revealed that although most students return to the university system in the first year after dropout, many of these change to a different area of knowledge, which is clear evidence of dysfunctional and inefficient guidance systems and university entrance. Findings provide a more accurate and complete picture of student re-enrolment behaviour and suggest the need to develop targeted policies to improve the efficiency and effectiveness of our university systems. 相似文献

The emergence and development of quality assurance schemes in European countries over the last 15–20 years has inspired many national case studies of the systems and procedures adopted. The methods, contexts, and procedures associated with this policy change are diverse. But although individual countries have set about changing policy in different ways there appear to be some common developmental patterns within the Europe of the Bologna Process. How can these developments be conceptualised? In a first step this paper advances a typology based on the quality assurance literature. In a second step, the paper applies the typology to quality assurance developments in three countries. The third part of the paper discusses the strengths and weaknesses of the modelling approach in the light of the empirical evidence and a political science analysis of policy change. The paper concludes with a discussion on future directions for the comparative study of policy change within the European Higher Education Area on the basis of this conceptualisation of developments in quality assurance policy. 相似文献

There has been a tendency in the literature to see changes in quality assurance as part of a process of increased state control. This article suggests a more nuanced approach that also takes account of the different trajectories of the pre‐ and post‐1992 sectors. It finds that whilst there have been increases in both state oversight and market coordination since 1992, mutuality (self‐regulation) remains the dominant mode of control of quality assurance in the United Kingdom. However the present government's higher education reforms, coming on top of a series of market‐based policies for structure, funding and governance going back at least to 1980, as well as a growing emphasis on students' rights as consumers through the courts, may change the picture. 相似文献

Intellectual disability (ID) is associated with a range of risk factors that make children more vulnerable to adverse developmental outcomes, including mental health problems. Nevertheless, some children with ID do much better than others, presumably because of the presence of protective factors that increase their resilience. The current study compared resiliency profiles of children with ID (n = 115; mean age, 11.9 years) and their typically developing peers (n = 106; mean age, 11.8 years) using the Resiliency Scales for Children and Adolescents and the Healthy Kids Resilience Assessment. In many respects, children with ID and their typically developing peers reported similar levels of the protective factors that are associated with resilience. However, the children with ID reported higher levels of emotional sensitivity and lower tolerance, as well as fewer future goals. Compared with typically developing children, those with ID reported more support at school and less support within their communities. These findings have important implications for interventions that aim to promote positive developmental outcomes and to prevent the adverse sequelae that have been associated with low intelligence. 相似文献
