Against the background of an adaptation of Cognitive Load Theory to learner-controlled settings we investigated the impact of learner characteristics on information utilization strategies, cognitive load, and learning outcomes in a hypermedia environment. Based on the data of 79 students, five clusters of students were identified according to their learner characteristics by means of a cluster analysis. Further analyses showed that learners with more favorable characteristics (i.e., higher prior knowledge, more complex epistemological beliefs, more positive attitudes towards mathematics, better cognitive and metacognitive strategy use) tended to show a more adaptive example utilization behavior, reported less cognitive load, and solved more problems correctly than learners with less favorable characteristics.  相似文献

Value-based argumentation for designing and auditing security measures     

Brigitte Burgemeestre  Joris Hulstijn  Yao-Hua Tan 《Ethics and Information Technology》2013,15(3):153-171

Designing security measures often involves trade-offs between various types of objectives. Multiple stakeholders may have conflicting demands and may have different ideas on how to resolve the resulting design conflicts. This paper reports on an application of value-sensitive design. Based on argumentation theory and social values, the paper develops a structured approach for discussing design conflicts, called value-based argumentation. The application domain examined in the paper is concerned with physical safety and security issues that arise in cross-border shipments. We first identify the kinds of dialogues that take place in this domain, in particular, audit dialogues to determine whether security measures comply with regulations. Based on argumentation theory we develop a formal language and a diagramming approach intended to facilitate parties in identifying, discussing and reaching agreement about security risks and corresponding mitigation measures. Trade-offs can be dealt with by making underlying values explicit. Using a stylized example, the approach was successfully taught to practitioners working with EU customs regulations. Practitioners generally found the approach helpful, in particular to bring out implicit underlying motivations. We conclude by discussing how our approach can be generalized to other kinds of dialogues involving design conflicts.  相似文献

Institutional abuse of children in the Austrian Catholic Church: Types of abuse and impact on adult survivors’ current mental health

The aim of this study was to explore the nature and dimensions of institutional child abuse (IA) by the Austrian Catholic Church and to investigate the current mental health of adult survivors. Data were collected in two steps. First, documents of 448 adult survivors of IA (M = 55.1 years, 75.7% men) who had disclosed their abuse history to a victim protection commission were collected. Different types of abuse, perpetrator characteristics, and family related risk factors were investigated. Second, a sample of 185 adult survivors completed the Posttraumatic Stress Disorder Checklist (PCL-C) and the Brief Symptom Inventory (BSI). Participants reported an enormous diversity of acts of violent physical, sexual, and emotional abuse that had occurred in their childhood. The majority of adult survivors (83.3%) experienced emotional abuse. Rates of sexual (68.8%) and physical abuse (68.3%) were almost equally high. The prevalence of PTSD was 48.6% and 84.9% showed clinically relevant symptoms in at least one 1 of 10 symptom dimensions (9 BSI subscales and PTSD). No specific pre-IA influence was found to influence the development of PTSD in later life (e.g. poverty, domestic violence). However, survivors with PTSD reported a significantly higher total number of family related risk factors (d = 0.33). We conclude that childhood IA includes a wide spectrum of violent acts, and has a massive negative impact on the current mental health of adult survivors. We address the long-term effects of these traumatic experiences in addition to trauma re-activation in adulthood as both bear great challenges for professionals working with survivors.  相似文献   

Long-term endurance training increases serum cathepsin S and decreases IL-6 and hsCRP levels     

Michael Sponder  Ioana-Alexandra Campean  Michael Emich  Monika Fritzer-Szekeres  Brigitte Litschauer  Jutta Bergler-Klein 《Journal of sports sciences》2017,35(21):2129-2134

Cathepsin S (CS) was shown to play a key role in cancer progression, atherosclerosis, heart valve disease, insulin resistance and diabetes mellitus. The present prospective study aimed to investigate the influence of sports on CS, interleukin-6 (Il-6) and high-sensitivity C-reactive protein (hsCRP) levels.

Ninety-eight of 109 participants completed the study. Ergometries were performed at baseline and after 8 months to evaluate/quantify the performance gain. Blood samples were taken at baseline and every 2 months. CS was measured by ELISA (enzyme-linked immunosorbent assay). Compared to the control group (mean performance gain ?3.41 ± 4.62%) we observed a significant physical-activity-induced increase of CS levels (3.45–3.73 ng · ml^?1; P = 0.027) and a significant decrease of Il-6 (2.43–1.91 pg · ml^?1; P = 0.031) and hsCRP-levels (0.11–0.09 mg · dl^?1; P = 0.001) in the intervention group (mean performance gain: 12.13 ± 6.32%). Furthermore, the tendency of the progression was significant for CS and Il-6 (P = 0.002/0.033).

We could show a significant sports-induced decrease of the classic inflammation parameters hsCRP/Il-6, probably expressing a downregulation of permanently prevalent inflammation processes. Simultaneously CS levels increased significantly. Our results show that increasing CS amounts are not simply to equal with an enhanced inflammation status and might even have beneficial effects on inflammation and angiogenesis.  相似文献   

The socialization of German university teachers: Some observations on role acquisition in an academic context and the consequent institutional effects     

Brigitte Eckstein 《Higher Education》1977,6(2):135-138

Recent trends in universities in the German Federal Republic are reviewed with special reference to the norms, values and attitudes of university teachers. Despite democratising influences the head of department is still a powerful figure. Recruits to the university teaching profession tend to conform to traditional values and ideas about the university. This has implications for the importance given to teaching. It is suggested that change may be brought about by helping academic staff to understand more fully the practical implications of the maintenance of traditional positions and also by exploiting opportunities which appear in the course of organising workshops devoted to the improvement of teaching in higher education.This is an abbreviated version prepared by the Coordinating Editor, of a longer article, available from the author, dealing with the topic at greater length. We are grateful for permission to include this study in the special issue on academics - Coordinating Editor.  相似文献   

When to say when: Using big data to support mobile communications     

Terry Cottrell  Brigitte Bell 《College & Undergraduate Libraries》2016,23(3):315-322

As a result of the current mobile phenomenon, many libraries have rushed to provide mobile-compatible services in order to remain relevant in today's quickly evolving information services market. Beginning in 2010, the Laverne and Dorothy Brown Library at the University of St. Francis (USF) launched a data tracking initiative via Google Analytics to determine the extent that mobile-specific library resources were being utilized by students for access to library materials and services. Data analysis has shown that weighing an emphasis toward future development of mobile library resources should be balanced against development costs under a pragmatic anticipation of the longevity and sustainability of any mobile resource.  相似文献
