OBJECTIVES: This study had two primary objectives: First, to examine the nature and co-occurrence of various forms of child maltreatment (sexual, physical, emotional, and witnessing violence) reported by Latina college students, and second, to explore coexisting maltreatment types and acculturation status as possible contributors to long-term adjustment difficulties. METHOD: Participants were 112 Latina undergraduate students categorized by the number of childhood maltreatment types experienced (0, 1, or 2 or more) and acculturation level (1 to 5). The possible effects of co-occurring forms of maltreatment, in conjunction with acculturation status, were investigated with respect to participants' reported trauma symptomatology. Data were collected using self-report measures. RESULTS: Nearly three out of 10 participants (29%) experienced more than one type of child maltreatment and, as expected, these individuals reported greater trauma symptomatology than those reporting either a single type of maltreatment or no maltreatment at all. Those who reported multiple types also endured more severe maltreatment than did respondents who experienced a single type. Acculturation level was neither directly related to trauma symptoms nor did it moderate the lasting correlates of maltreatment among victims. Interestingly, those who experienced a single form of maltreatment reported no more trauma symptoms than did participants who reported no maltreatment history at all. CONCLUSION: This investigation documents a large degree of overlap among various forms of self-reported childhood maltreatment within a Latina college population. The results underscore the need to consider multiple forms of maltreatment, as well as severity, when making inferences regarding potential effects on later functioning.  相似文献   

Redesigning chat forum for critical thinking in a problem-based learning environment     

Akcell Chii-Chung Chiang  Isaac Pak-Wah Fung 《The Internet and Higher Education》2004,7(4):311-328

Support is needed to promote problem-based learning (PBL) and to enhance critical thinking skills in discussion-based Internet forums. By advancing the capabilities of chat room and forum software, problem-based discussions for learning can be supported further in online learning environments. In this paper, the authors report on MALESAbrain, an intelligent learning tool. The model is built on the notions of threshold and knowledge weight from the discipline of machine learning. The model encourages learners to judge or critically evaluate the solutions posted by others before exploring further knowledge content. The system then sums up the judgment scores as its knowledge weight to pass the thresholds setup for ranking/arranging the learning issues. This constraint design, therefore, becomes a mechanism for critical thinking in a problem-based learning activity. MALESAbrain as a model helps transform the forum and chat room into rich learning discussion environments.  相似文献

Geography teaching in the twenty-first century     

Antoine Bailly 《Prospects》1995,25(4):783-790

Conclusion At a time when transnational communities are being created which extend beyond the confines of regions and natio-States, geographers are questioning the very foundations of their discipline and their function in society. Not only do they no longer avoid acknowledging their role in the transmission of spatial, regional and national identity, but they no longer act solely within the framework of the nation-State. The juxtaposition of local and world considerations prompts them to embark upon new inquiries tending towards the teaching of a conceptual and topical geography which can mobilize pupils and teachers alike according to broad social, temporal and spatial principles. Human beings, frail creatures of the earth, have only one real tool adapted to the vastness of the spaces with which we have to grapple: the mind (Ratzel, 1988). Born in 1944. Professor of geography at the University of Geneva, having taught in Canada and France. He holds a doctorate from the Sorbonne and has studied geography and regional sciences in France and the United States of America. He has been chief examiner at the International Baccalaureat Office. He is now President of the Western Regional Science Association and the Swiss Association of University Lecturers. His recent publications, as author or editor, include:Encyclopédie de géographie [Encyclopedia of geography] (2nd ed., 1995),Introduction à la géographie humaine [Introduction to human geography] (5th ed., 1995) andLes concepts de la géographie [Geographical concepts] (3rd ed., 1995).

Private and Public Schooling in Ghana: A Census and Comparative Survey     

James Tooley  Pauline Dixon  Isaac Amuah 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》2007,53(4):389-415

A census and survey of schools in the district of Ga, Ghana, explored the nature and extent of private education, and compared inputs to public and private schooling. Three quarters of all schools found were private, with almost as many unregistered private as government schools. Several important differences between registered and unregistered private schools were noted, including age, fee levels charged, teacher salaries and class size. A range of inputs, such as teacher activity, availability of desks, chairs, libraries, toilets and drinking water, were used to compare inputs to government, unregistered and registered private schools. Some conclusions are explored about the potential role for the private sector in helping meet “education for all” targets.  相似文献   

A scale-based approach to interdisciplinary research and expertise in sports     

Jorge Ibáñez-Gijón  Martinus Buekers  Antoine Morice  Guillaume Rao  Nicolas Mascret  Jérome Laurin 《Journal of sports sciences》2017,35(3):290-301

After more than 20 years since the introduction of ecological and dynamical approaches in sports research, their promising opportunity for interdisciplinary research has not been fulfilled yet. The complexity of the research process and the theoretical and empirical difficulties associated with an integrated ecological-dynamical approach have been the major factors hindering the generalisation of interdisciplinary projects in sports sciences. To facilitate this generalisation, we integrate the major concepts from the ecological and dynamical approaches to study behaviour as a multi-scale process. Our integration gravitates around the distinction between functional (ecological) and execution (organic) scales, and their reciprocal intra- and inter-scale constraints. We propose an (epistemological) scale-based definition of constraints that accounts for the concept of synergies as emergent coordinative structures. To illustrate how we can operationalise the notion of multi-scale synergies we use an interdisciplinary model of locomotor pointing. To conclude, we show the value of this approach for interdisciplinary research in sport sciences, as we discuss two examples of task-specific dimensionality reduction techniques in the context of an ongoing project that aims to unveil the determinants of expertise in basketball free throw shooting. These techniques provide relevant empirical evidence to help bootstrap the challenging modelling efforts required in sport sciences.  相似文献

Comparison of two methodological approaches for the mechanical analysis of single-joint isoinertial movement using a customised isokinetic dynamometer*     

Mathieu Plautard  Gaël Guilhem  Vincent Fohanno  Antoine Nordez  Christophe Cornu 《Sports biomechanics / International Society of Biomechanics in Sports》2018,17(3):287-302

Compared to isokinetic and isometric tests, isoinertial movements have been poorly used to assess single-joint performance. Two calculation procedures were developed to estimate mechanical performance during single-joint isoinertial movements performed on a customised isokinetic dynamometer. The results were also compared to appreciate the effects of measurement systems and calculation procedures. Five participants performed maximal knee extensions at four levels of resistance (30, 50, 70 and 90% of the one-repetition maximum, 1-RM). Joint angular velocity and torque were assessed from customised isokinetic dynamometer measures (method A) and from weight stack kinematic (method B). Bland–Altman plots and mean percent differences (M_diff) were used to assess the level of agreement for mean and peak angular velocity and torque. A Passing–Bablok regression was performed to compare the angular velocity-angle and torque-angle relationships computed from the two analysis methods. The results showed a high level of agreement for all mechanical parameters (M_diff < 6% for all parameters). No statistically significant differences were observed between methods A and B in terms of angular velocity-angle and torque-angle relationships except at 30% of 1-RM for the torque-angle relationship. Both methodologies provide comparable values of angular velocity and torque, offering alternative approaches to assess neuromuscular function from single-joint isoinertial movements.  相似文献
