Bibliometric mapping of computer and information ethics

This paper presents the first bibliometric mapping analysis of the field of computer and information ethics (C&IE). It provides a map of the relations between 400 key terms in the field. This term map can be used to get an overview of concepts and topics in the field and to identify relations between information and communication technology concepts on the one hand and ethical concepts on the other hand. To produce the term map, a data set of over thousand articles published in leading journals and conference proceedings in the C&IE field was constructed. With the help of various computer algorithms, key terms were identified in the titles and abstracts of the articles and co-occurrence frequencies of these key terms were calculated. Based on the co-occurrence frequencies, the term map was constructed. This was done using a computer program called VOSviewer. The term map provides a visual representation of the C&IE field and, more specifically, of the organization of the field around three main concepts, namely privacy, ethics, and the Internet.

Constructing the academic category of teacher educator in universities’ recruitment processes in Aotearoa,New Zealand

An examination of recruitment materials and interviews with personnel involved in the employment of teacher educators to positions in university-based New Zealand initial teacher education (ITE) courses reveals three constructions of teacher educator as academic worker: the professional expert, the dually qualified, and the traditional academic. However, this study’s analysis shows how these constructions allow universities to pursue a bifurcated approach for the employment of teacher educators, an approach that maintains binaries within teacher education and hinders development in the field. Furthermore, as the spectre of a major cultural shift in the provision of New Zealand ITE arises, the extent to which the professional expert and traditional academic constructions of teacher educator might serve the scope of work required of postgraduate ITE going forth is questioned.     

Highbrows in University Education

Is it still possible to combine two programmes of study in higher education, and if so, what are the characteristics of these double‐students and what kind of obstacles do they face? In the Netherlands, about 10 percent of students in university education take two studies at the same time.

Different theoretical approaches offer hypotheses to explain the choice of students for a second study, compared to students who pursue the regular one‐study programme. Human capital as well as financial (socio‐economic) capital theory provides some insights in this choice process. Education programme‐related factors, as well as motivational and (social and academic) integration (Tinto, 1987 Tinto V 1987 Leaving College: Rethinking the Causes and Cures of Student Attrition Chicago The University of Chicago Press  [Google Scholar]) factors, will possibly be important determinants for pursuing one or two study programmes in higher education.     

Initial-link duration and acquisition of preference in concurrent chains

Initial-link response allocation in concurrent chains becomes less extreme as the absolute duration of the initial links increases (Fantino, 1969). The present study asked whether initial-link duration affected how quickly response allocation reached asymptote (i.e., acquisition of preference). Six pigeons were trained on a concurrent-chains procedure in which the terminal links were fixed-interval (FI) 8 sec FI 16 sec or FI 16 sec FI 8 sec and were reversed every 20 sessions. Across conditions, all possible combinations of transitions between variable-interval (VI) 8-sec (short) and VI 24-sec (long) initial-link schedules were studied. Overall, the rate of acquisition was faster when the durations of the initial links preceding the reversal were short rather than long, and when the durations of the initial links following the reversal were long rather than short. By contrast, initial-link duration had no effect on acquisition or asymptotic measures of temporal control of terminal-link responding. These results support the core principle of delay-reduction theory (Fantino, 1969) that the impact of a conditioned reinforcer varies directly with initial-link duration, but also suggest that temporal learning during the terminal links proceeds independently of initial-link duration. nt]mis|These data were presented at the annual meeting of the Association for Behavior Analysis, Boston, May 2004.     

Peer assessment in university teaching: evaluating seven course designs

Peer assessment is understood to be an arrangement with students assessing the quality of their fellow students’ writings and giving feedback to each other. This multiple‐case study of seven designs of peer assessment focuses on the contribution of peer assessment to the acquisition of undergraduates’ writing skills. Its aim is to arrive at an optimal design of peer assessment. Factors included in this study are: the quality of peer assessment activities, the interaction between students in oral peer feedback, students’ learning outcomes, and their evaluation of peer assessment. Most students took assessing the work of their fellow students seriously, and included the peer feedback in the revision of their work. In most conversations, students provided feedback in an evaluative manner. In others, the interaction was more exploratory. For peer assessment, we recommend a combination of written and oral peer feedback.
