Learning technologies at the service of higher education: global trends and local Israeli opportunities

This paper provides an overview of global trends in e-Learning and opportunities opened by harnessing learning technologies at the service of the Israeli higher education. The introduction of innovative learning technologies is examined in light of an organizational change. A series of substantial issues should be taken into account to successfully manage the change. Among these are: rethinking of academic learning and instruction, redefining the role of the teachers and the students, decoupling the learning materials and the learning process, new approaches to student assessment and program evaluation, and instituting a well thought out organizational plan including a support center. The above-mentioned issues guided the introduction of a recent call for project proposals for the integration of technologies into Israeli higher education. The main principles, criteria and results of this call are described.

Bite Mark Evidence in Crimes Against Persons

Abstract

Bite marks are often found on victims of homicide, sex crimes, and child abuse. Since this type of physical evidence often links victims and assailants, it is essential that bite mark evidence be recognized and properly preserved. The superior courts of several states and United States military courts have accepted this evidence as admissible.

This article is intended to familiarize college and university health workers and security personnel with the appearance of bite marks as they may be found on victims. Further, it describes techniques of photography and related procedures, necessary for the preservation of this essential evidence. Photographs of actual bite marks and diagrams illustrating correct techniques for photography are included. This article is intended to alert college health and security personnel that early recognition and preservation of bite mark evidence is essential to investigative procedures.     

Deaths at the borders database: evidence of deceased migrants’ bodies found along the southern external borders of the European Union

Irregular migrants and asylum seekers have died and continue to die attempting to cross the external borders of the EU without authorisation, seeking to enter the territories of its Member States. Yet, remarkably little is known about these ‘border deaths’. In 2015, the Human Costs of Border Control project published the Deaths at the Borders Database for the Southern EU, an open-source ‘evidence base’ of individualised information about people who have died border deaths between 1990 and 2013, sourced from the death management systems of Spain, Gibraltar, Italy, Malta and Greece. It is the first database on border deaths in the EU to be based on official sources as opposed to the news media. The project involved searching 563 state-run death registry archives and deductively selecting the death certificates of persons who died border deaths. This paper describes, in detail, the making of the Deaths at the Borders Database: from the systematic, multi-sited, quantitative data collection and qualitative case studies, to the construction and final results of the Database itself.     

日常知识与生活世界——知识社会学的现象学传统评析

现象学社会学构成知识社会学的一个重要传统。它关于日常知识的生成机制和建构社会的功能的基本思想,揭示了日常知识同生活世界之间辩证的交互建构关系,以及个体知识同社会共享知识之间的转化机制。现象学社会学关于生活世界的日常知识是一种"现实感"的阐释,既显现知识同主观世界的关联,也没有否定知识的客观性,在知识的客观真实性问题上提出了不同于知识社会学其它学派的主张。它对常识知识的关注及其社会建构论思想,对当代知识社会学的发展均有重大贡献。     

The Internalization of the “Father” Object Among Young Men and Its Relation to Separation–Individuation Patterns, Anxiety and Depression

While the father’s influence on his offspring’s personalities and well-being has historically been neglected, literature on this topic has recently been accumulating. The father’s influence is touches upon numerous practical and ethical implications for social work, psychotherapy, and psychodiagnosis. The present study draws from Mahler’s (Mahler, Separation individuation. The selected papers of Margaret S. Mahler, 1963, 1967, 1974; Mahler et al., The psychological birth of the human infant. Symbiosis and individuation, 1975) theory of the psychological birth of the child and offers a novel focus on the pivotal internal representation of the father. According to this theory, hindered developmental processes lead to depression and anxiety. 130 students took part in the current study, in which the internal father object was examined with regard to separation–individuation processes, and the levels of anxiety and depression were recorded. The study’s results show a significant negative relation between the quality of the paternal object and levels of anxiety and depression. A theoretical model was constructed to illustrate the similarities and discrepancies in the development of depression and anxiety in light of the father object as mediated by the separation–individuation processes that were examined.     

壳聚糖涂膜对芒果采后品质及生理特性的影响

为了探讨壳聚糖涂膜保持芒果采后品质的相关生理机制,以‘台农1号’芒果(Mangifera indica L.‘Tainong No.1’)为材料,研究了1.0％壳聚糖涂膜处理对芒果在常温(28～30℃)贮藏条件下果实品质及生理特性的影响.结果表明,与对照相比,壳聚糖涂膜处理显著降低了果实的失重率和病果率,延缓了果皮颜色的转黄,保持较高的果实硬度;并且,壳聚糖涂膜有效保持了果实品质,能够显著延缓芒果可滴定酸(TA)含量的降低和可溶性固形物(TSS)含量的升高,维持芒果果实较高的Vc含量;同时,壳聚糖涂膜也提高了芒果果实贮藏后期超氧化物歧化酶(SOD)和过氧化物酶(POD)的活性,并抑制MDA含量的积累,降低膜脂过氧化程度,从而延缓了采后芒果的后熟衰老进程.
