Conceptions of ethical competence in relation to action readiness in Education for Sustainable Development

This paper explores notions of ethical competence in relation to Education for Sustainable Development (ESD). It carves out a conceptual field for future empirical research, by coupling the promotion of action readiness as an empirical concept with a theoretical understanding of ethical competence. The concept of competence displays interpretative pluralism as a concrete attribute of an individual or task and an unattainable ideal beyond the specific. With interpretive care, ethical competence, with its origin in values education, is suggested as a foundation of action readiness as ESD competence. In educational practice, action readiness is assumed to be fostered through real-world learning opportunities.     

Do elderly couples have a better prospective memory than other elderly people when they collaborate?

A naturalistic study investigated how memory tasks affected group productivity for two individuals working in three kinds of group constellations: old married couples, old non‐friend pairs, and nominal groups of two individuals working on their own. The retrospective memory task was to recall episodic information given on a visit to a university campus. The prospective memory task was to remind the participants of actions to be performed during the visit. The prospective memory tasks were event‐based or time‐based. The delay or retention interval was also manipulated. In addition, an interview on how the elderly handled remembering during daily life was included. The results suggest that: (1) dyads suffered from collaboration relative to the predicted potential, replicating earlier research; old married couples did not reduce the same productivity loss as clearly as friends did in former studies; the couples who claimed that they used a transactive memory system, however, achieved the same productivity as the nominal pairs (i.e. the predicted potential; (2) the task effects produced unexpected results, some of which could be accounted for by the naturalistic setting used.

The social value of risk-taking

In this study, the following hypothesis concerning the social value of risk-taking is advanced: young men who wish to assert themselves and to gain prestige tend to take greater risks in public when together with other young men than do young men who do not have these wishes, whereas there is no such difference in risk-taking in private. This hypothesis is empirically tested and is supported.     

Plato on Necessity and Disorder

In the Timaeus, Plato makes a distinction between reason and necessity. This distinction is often accounted for as a distinction between two types of causation： purpose oriented causation and mechanistic causation. While reason is associated with the soul and taken to bring about its effects with the good and the beautiful as the end, necessity is understood in terms of a set of natural laws pertaining to material things. In this paper I shall suggest that there are reasons to reconsider the latter part of this account and argue for a non-mechanistic understanding of necessity. I will first outline how the notion of necessity is introduced in the dialogue. Next I will show how a mechanistic account of necessity fails to capture Plato＇s purpose of treating it as a causal factor; and, finally, I will argue that this purpose is better understood as an attempt, on Plato＇s part, to account for the causal origin of disorder and irrationality, an origin articulated in terms of a pre-cosmic situation and the notoriously difficult notion of the third kind.     

Differentiating Type A behaviour and hyperactivity using observed motivation during a reaction time task

In light of the previously found overlap between Type A behaviour as measured by the Matthews Youth Test for Health (MYTH) and hyperactivity scales, the overall aim of this study was to clarify the standing of MYTH‐defined Type A behaviour relative to hyperactivity and Attention‐Deficit/Hyperactivity Disorder (ADHD), using observed task motivation and performance on a choice reaction‐time task, the Complex Reaction Time (CRT) measure. This study included 21 boys exhibiting Type A behaviour, 22 ADHD boys, 20 non‐clinically hyperactive boys, and 20 non‐hyperactive boys, between the ages of 6 and 13 years. It was proposed that a differentiation of constructs would be possible using observed task motivation if the MYTH were a discriminantly valid measure of Type A behaviour. Results showed that the MYTH‐defined Type A group differed from the clinically diagnosed ADHD group, although it was markedly similar to the non‐clinical hyperactive group, displaying comparable CRT performance and low level of task motivation. Type A behaviour correlated to CRT performance and task motivation in a way which was conceptually more indicative of hyperactivity than of Type A behaviour, which questions the validity of the MYTH as a measure of the Type A construct. The MYTH Impatience subscale was found to be particularly impure with regard to hyperactivity. Copyright © 2003 John Wiley & Sons, Ltd.     

Fatigue Impact Scale: Its validation in patients with chronic obstructive pulmonary disease

The aim of this study was to investigate the reliability and validity of the Fatigue Impact Scale (FIS) among patients with chronic obstructive pulmonary disease (COPD) and shorten the questionnaire. The empirically developed FIS, which comprised three subscales (cognitive, physical and psychosocial), was tested originally on Pipers' theoretical framework of subjective manifestations of fatigue, including behavioural, physical, emotional and cognitive expressions. The data analysed here consisted of responses from 296 patients with COPD who reported fatigue. The dimensionality of the FIS was examined using confirmatory factor analysis. A reduction of 15 items from the original FIS was made based on theory, modification indices and factor loadings. The results indicate that a nested-factor model with one general behavioural factor and three specific factors, physical, emotional and cognitive, shows acceptable fit. A modified version of 25 items, FIS-25 was developed. The original FIS and the FIS-25 were able to discriminate between patients with differing duration of fatigue. Test - retest correlations ranged from .70 to .85 for items and .94 for the total scale. Due to modification, the FIS-25 needs to be validated on a new group of patients with COPD.     

Compensating strategies in collaborative remembering in very old couples

This study investigates collaborative memory performance in very old married couples working in two types of participant constellations, and with two types of memory tasks, i.e. working as couples, or as individuals in episodic or semantic memory tasks. Sixty-two old married couples were a priori classified as high or low on two dimensions suggested to be important for successful collaboration, i.e. responsibility (how division of responsibility was organized) and agreement (how they mutually agreed on each other's view). The episodic memory task was immediate recall of short stories. The semantic memory tasks were to answer questions about names, places, and concepts. The results suggested that: (1) groups outperformed a single individual, but (2) groups in general suffered from collaboration relative to the predicted potential in episodic tasks only, thus replicating earlier results. Nevertheless, (3) the couples scoring high on division of responsibility achieved the same productivity as nominal pairs (i.e. the predicted potential); (4) the couples scoring high on the agreement dimension showed that they were not as affected by collaboration, but then performed less well in "absolute" performance. Finally, the results were discussed in terms of optimal compensation strategies, especially for elderly couples.     

Cognition and the Planning Process: An Investigation of Stability of Effects and Decision Makers' Insights

According to Hartman, White, and Crino (1986), planning situations differ in environmental volatility, system adaptation, and the nature of planning requirements, different combinations of which can generate 12 distinct planning situations and 8 information processing aids to be used as planning tools. Each information processing aid has been prescribed to be more appropriate for use in some planning situations than in others (Hartman et al.). In the first part of this study, we tested the hypothesis that a planner in a specific situation would prefer to use the information processing aid(s) prescribed for that situation. We developed 12 different cases and used 456 student subjects. Results indicated that preference did not correspond closely to the Hartman et al. theory but that some other form of implicit theory may be operating. The second part of the research replicated the first part and also examined how 57 subjects viewed their planning problems and weighed the factors involved. Part 2 was also designed to determine the nature of any implicit theory the subjects may have used. Results suggest that the pattern of preferences, although not corresponding to available theory, represents a stable phenomenon.
