Eight Dialectic Benchmarks Discussed By Two Artificial Localist Disputors

Dispute types can roughly be divided in two classes. One class in whichthe notion of justification is fundamental, and one in which thenotion of opposition is fundamental. Further, for every singledispute type there exist various types of protocols to conduct such adispute. Some protocols permit local search (a process in which oneis allowed to justify claims partially, with the possibility to extendjustifications on request later), while other protocols rely on globalsearch (a process in which only entire arguments count as justifications).This paper integrates the two above-mentioned types of dispute withthe use of a protocol that permits local search. The locality aspect isrelatively new to computer scientists, while the detailed computationalelaboration of the approach is relatively new to philosophical logicians.The proposed protocol is demonstrated with the help of eight benchmarks.These benchmarks are centered around the problem that co-concludingarguments sometimes accrue, and sometimes do not.     

Thinking styles, self-esteem, and socio-economic status

The present study aimed at examining the nature of thinking styles. Six hundred and ninety-four students (ages ranging from 17–45) from the University of Hong Kong participated in the study. The participants responded to the Thinking Styles Inventory and the Self-Esteem Inventory (Adult Form) and provided a range of socio-economic status (SES) indicators. It was found that when age was controlled, thinking styles and self-esteem overlap. Furthermore, regardless of age, those students who reported using thinking styles that are creativity-generating and more complex, and those who reported higher self-esteem tend to be students from higher SES families. Discussion was made in relation to these findings' practical implications for teachers.     

Cultural Mistrust,Ethnic Identity,Racial Identity,and Self‐Esteem Among Ethnically Diverse Black University Students

Cultural mistrust, ethnic identity, racial identity, and self‐esteem were examined among African (n = 26), African American (n = 110), and West Indian/Caribbean (n = 24) university students. African American students' scores were statistically different from those of African and West Indian/Caribbean students on cultural mistrust, racial identity, and ethnic identity measures. There were no statistically significant differences on self‐esteem among the 3 groups. Results did indicate that cultural mistrust, ethnic identity, and racial identity accounted for 37% of the variance in self‐esteem for African American students. Implications for practice and future research directions are discussed.

The Role of Situational Interviews in Fostering Positive Reactions to Selection Decisions

We investigated the effect of interview format and employment equity program strength on perceptions of fairness. We used job seekers and vignettes to test the hypotheses. The participants reported lukewarm support for employment equity programs. The use of a situational interview in the selection process of an organisation that had adopted an employment equity program contributed to higher perceptions of fairness vis‐à‐vis the use of an unstructured interview. The results also showed that the inclusion of a situational interview in the selection process mitigated negative reactions to the selection decision when a strong employment equity program was in place as well as when a female visible minority was hired. Nous avons évalué l'impact sur la perception de justice du style d'entretien et de la rigueur d'une charte d'équité relative à l'emploi. On a fait appel à des demandeurs d'emploi et utilisé un test de jugement situationnel pour éprouver les hypothèses. Les répondants se sont montrés peu enthousiastes en ce qui concerne les chartes d'équité relatives à l'emploi. Le choix d'un entretien structuré dans le processus de sélection d'une organisation qui avait adopté une charte d'équité relative à l'emploi a amélioré la perception de justice portant sur un entretien ordinaire. Il apparaît aussi que la présence d'un entretien structuré dans le processus de sélection atténuait les réactions négatives consécutives au résultat de la sélection quand existait une sérieuse charte d'équité relative à l'emploi et quand était embauchée une minorité féminine non négligeable.     

Brightness indention: A novel compression mechanism in the luminance-brightness mapping

In a previous study, Schouten and Blommaert (1995) explicitly showed that brightness constancy implies a substantial compression in the luminance-brightness mapping. Here it is argued that additional compression mechanisms are required for scenes with large luminance ranges. To trace these, a series of experiments was conducted which involved expansion of the luminance range. We used a simple spatial configuration consisting of a disk on a contourless homogeneous surround (Ganzfeld). The contrast between the disk and Ganzfeld acted as the independent variable, while the size of the disk was parametrically varied. Sequential dichoptical brightness matches with a reference were carried out for both the disk and the surround. The results reveal a compression mechanism which we termbrightness indention. This indention, which has not previously been reported in the literature, only occurs if the Ganzfeld is less luminous than the disk, and it takes the form of a brightness decrease of the immediate surroundings of the disk.     

A model of a psychological service for adults in a formal educational setting

This article describes the development and operation of a psychological service addressing the needs of adults in a formal educational setting. The structure and content of the service differs significantly from that historically available to children or adolescents in Irish schools. The major elements in the service - induction course, workshops, personal growth groups, and individual counselling - are detailed. The present research builds on an earlier investigation by the same authors into the needs of adults in full-time education at Pearse College, Dublin.
