张文德 《数字图书馆论坛》2006,(12):77-77

面向服务的体系结构、对等网络和网格技术的发展为数宇图书馆体系结构的研究和应用带来了新的机遇，使其在开放性和柔性方面的拓展成为可能。下一代数字图书馆应当是能为更多用户服务的、自适性更强的服务组织，它是以联邦模式进行资源库的构建和服务的组织。与传统数字图书馆相比，下一代数字图书馆的体系结构将更为分布和动态，从而适应资源库、元数据和服务所呈现出的高度异构性。  相似文献

Recognition of facial emotions among maltreated children with high rates of post-traumatic stress disorder

OBJECTIVE: The purpose of this study is to examine processing of facial emotions in a sample of maltreated children showing high rates of post-traumatic stress disorder (PTSD). Maltreatment during childhood has been associated independently with both atypical processing of emotion and the development of PTSD. However, research has provided little evidence indicating how high rates of PTSD might relate to maltreated children's processing of emotions. METHOD: Participants' reaction time and labeling of emotions were measured using a morphed facial emotion identification task. Participants included a diverse sample of maltreated children with and without PTSD and controls ranging in age from 8 to 15 years. Maltreated children had been removed from their homes and placed in state custody following experiences of maltreatment. Diagnoses of PTSD and other disorders were determined through combination of parent, child, and teacher reports. RESULTS: Maltreated children displayed faster reaction times than controls when labeling emotional facial expressions, and this result was most pronounced for fearful faces. Relative to children who were not maltreated, maltreated children both with and without PTSD showed enhanced response times when identifying fearful faces. There was no group difference in labeling of emotions when identifying different facial emotions. CONCLUSIONS: Maltreated children show heightened ability to identify fearful faces, evidenced by faster reaction times relative to controls. This association between maltreatment and atypical processing of emotion is independent of PTSD diagnosis.  相似文献

Developing identity and agency as an early career academic: lessons from Alice     

Sue Monk  Loraine McKay 《International Journal for Academic Development》2017,22(3):223-230

This paper draws on Lewis Carroll’s character of Alice as a metaphor for interrogating identity construction and agency amongst early career academics, a process which can seem like Alice’s pursuit of the White Rabbit in a strange land. Keeping in mind the effects of neoliberalism on the tertiary sector, we recognise the centrality of personal lives in decision-making about academic careers and the shaping of professional identities. We also foreground how communities of practice not only build agency amongst ECAs but can also be supported by academic developers.  相似文献   

The questionable role of higher education as an occupational screening device     

Abraham E. Haspel 《Higher Education》1978,7(3):279-294

Employers optimally pursue activities which facilitate the coordinating of employee characteristics and the requirements of the job. One allegedly important employee characteristic is the level of education. Employees with higher levels of education are rewarded with higher wages than employees with lower levels. This may occur if higher levels of education make an employee truly more productive or if because of an employer's beliefs only those individuals with higher levels of education are allowed to enter the higher paying positions (occupational screening).The above propositions are testable, depending crucially upon the theoretical model employed for determining occupational choices. We shall compare the implications of two possible occupation choice models: (1) enter the job which offers the highest lifetime income, (2) enter the job which offers the highest level of overall satisfaction. We estimate these two models using the NBER-TH data sample. By distributing our estimated results and the actual distribution of occupations over the education levels of high school, some college and BA we can see if more or less people are expected to enter specific occupations at each education level. Support for screening exists if more people are expected in high status occupations at low education levels than are actually in those occupations.When comparing the estimated results for each model we see different outcomes emerge. The latter indicates that screening does not exist while the former does. We present arguments as to why we feel that the second model is the more correct and appropriate and, consequently, why we feel that education is not an effective screening device.  相似文献   

The necessity of each phase of the learning cycle in teaching high school physics     

John W. Renner  Michael R. Abraham  Howard H. Birnie 《科学教学研究杂志》1988,25(1):39-58

The learning cycle is a method of teaching—it is also a curriculum organization principle and is derived directly from the mental functioning model invented by Piaget. Although Jean Piaget contributed to the formation of the learning cycle (Piaget, 1973), its present structure has to be attributed to Dr. Robert Karplus and the persons who developed the materials of the Science Curriculum Improvement Study (SCIS). It was through the SCIS activities that many of us learned how to develop curricula and teach with the learning cycle. The learning cycle is built upon the premise that three distinct phases are necessary in developing understanding of a concept, that those phases have a definite sequence, and each phase has a definite structure or form. The research done in testing the form variable has already been reported in this journal (Renner, Abraham, & Birnie, 1985). This report explores whether or not each learning-cycle phase is necessary in learning a concept.  相似文献   

A SYSTEMIC,STUDENT-CENTERED STUDY OF UNIVERSITY SERVICE   总被引：1，自引：0，他引：1  

Brenders  David A.  Hope  Peter  Ninnan  Abraham 《Research in higher education》1999,40(6):665-685

This paper discusses the methods and findings ofthe Student Focus Project, a sixmonth study of studentperceptions of service at a large university inBrisbane, Australia. The study paneled 24 focus groups of undergraduate students to assess theirbeliefs about a pretested set of questions concerningpositive and negative aspects of university life,successes and frustrations with university service,attempts to overcome the obstacles of university life,and what students expect from their relationship to theuniversity. Of the themes identified in the StudentFocus study, it was found that malignantbureaucracy and the balkanization ofInformation are systemic factors that negativelyinfluence student perceptions of the quality ofuniversity service. It was also found that studentstrategies for service recovery can contribute to the overall confusion andpoor performance of university services.  相似文献   

Raised serum homocysteine levels in patients of coronary artery disease and the effect of vitamin B12 and folate on its concentration     

R Abraham  M Joseph John  R Calton  J Dhanoa 《Indian journal of clinical biochemistry : IJCB》2006,21(1):95-100

Homocysteine(Hcy) has been implicated as a novel risk factor of Coronary Artery Disease (CAD) among Asian Indians, but many studies done in India failed to reveal any direct correlation. It has also been reported that Folic acid and Vitamin B12 levels inversely affect serum levels of homocysteine. In this study, we looked at the levels of homocysteine among patients with CAD. The effect of Vitamin B12, Folate and other risk factors on homocysteine levels were also evaluated. Mean homocysteine levels in cases (22.81±13.9, n=70) were significantly higher (p=<0.001) than the controls (7.77±7.3, n=70). However no statistically significant correlation could be deduced between homocysteine Vitamin B12, and Folate. Cumulative analysis have indicated an increase in homocysteine levels among patients with CAD with every additional risk factor.  相似文献
