Ethical dilemmas in teaching and nursing: the Israeli case

This article explores a cross‐occupational approach for dealing with ethical dilemmas by comparing teaching and nursing. Findings indicate more shared patterns of ethical dilemmas (such as caring for needs for others versus following formal codes) than dilemmas specific to teaching (e.g., advancing universal values versus advancing knowledge) or nursing (e.g., patient modesty versus hospital policy). The large number of shared dilemmas suggests that results can be applied to a curriculum devoted to ethical dilemmas in high schools and universities in order to better prepare students to handle them. Formal discussions of these dilemmas can help define the roles of these occupations, thereby improving their status.     

Bidirectional delta files

A bidirectional delta file is a novel concept, introduced in this paper, for a two way delta file. Previous work focuses on single way differential compression called forwards and backwards delta files. Here we suggest to efficiently combine them into a single file so that the combined file is smaller than the combination of the two individual ones. Given the bidirectional delta file of two files S and T and the original file S, one can decode it in order to produce T. The same bidirectional delta file is used together with the file T in order to reconstruct S. This paper presents two main strategies for producing an efficient bidirectional delta file in terms of the memory storage it requires; a quadratic time, optimal, dynamic programming algorithm, and a linear time, greedy algorithm. Although the dynamic programming algorithm often produces better results than the greedy algorithm, it is impractical for large files, and it is only used for theoretical comparisons. Experiments between the implemented algorithms and the traditional way of using both forwards and backwards delta files are presented, comparing their processing time and their compression performance. These experiments show memory storage savings of about 25% using this bidirectional delta approach as compared to the compressed delta file constructed using the traditional way, while preserving approximately the same processing time for decoding.     

Undergraduate engineering—a comparative study of first year performance in single gender campuses

The Jerusalem College of Technology is an institution for higher education in Israel, where the majority of the students study towards an undergraduate degree in Engineering (Electronics, Applied Optics, Computers, etc.). The studies are held on three different campuses, one campus for men and two for women. We describe the organization of the Foundation Year (i.e. the basic first year courses), and discuss the similarities and differences between the male and female populations, with respect to their learning skills and performances.     

ICT-aided engineering courses: a multi-campus course management

Jerusalem College of Technology (JCT) is a multi-campus institution with identical syllabi for courses in every campus. Moreover, learning at JCT requires at the same time synchronous and asynchronous learning and teaching. For some introductory courses in Mathematics for Engineering students, websites have been built and now upgraded in order to fit the requirements due to multiple campuses. The original triple function model ‘homepage-tutorial-mailing list’ had to be modified in various directions, in order to fit the students' needs and the central role of the course coordinator. We discuss here the structure and management of the websites and the contribution of these supplementary materials towards teaching efficiency and towards students' better learning skills.     

How do class,status, ethnicity,and religiosity shape cultural omnivorousness in Israel?

In this article we study the determinants of cultural participation in Israel with an emphasis on the Weberian distinction between class and status. The class measure is based on occupational groupings, and status is operationalized as a rank of occupations based on social distance. We expect that class will be less important than status in shaping cultural participation patterns. In addition, due to the importance of ethnicity and religiosity in Israeli society, we expect that these factors will be significant in shaping cultural participation. Data are based on two telephone surveys conducted in 2006 and 2007 of a random sample of the Jewish population in Israel. We find that, contrary to our expectation, class is more influential than status. We also find that ethnicity and religiosity are important factors that shape cultural participation patterns. We discuss possible explanations to the finding regarding class and status, with special attention to the role cultural policy plays in mediating the economic effect on consumer behavior. We also call for more attention to ethnicity and religiosity in studies of cultural stratification.

Organizational and institutional influences on creativity in scientific research

This paper explores institutional and organizational influences on creativity in scientific research. Using a method for identifying creative scientific research accomplishments in two fields of science (nanotechnology and human genetics) in Europe and the US, the paper summarizes results derived from twenty case studies of highly creative research accomplishments, focusing on contextual patterns at the group, organizational, and institutional levels. We find that creative accomplishments are associated with small group size, organizational contexts with sufficient access to a complementary variety of technical skills, stable research sponsorship, timely access to extramural skills and resources, and facilitating leadership. A potential institutional threat to creative science is the increase in competitive research council funding at the expense of flexible institutional sponsorship. Implications for research management and research policy are considered.
