The legal basis for the Danish committee on scientific dishonesty

The author, a High Court Judge, has chaired the Danish Committee on Scientific Dishonesty (DCSD) since its establishment in 1992. The Committee has worked in the health sector, but from 1999 the scope has been broadened to cover all fields of science. The article describes how the work is organised and the experiences gained. It is stressed, that the difficulty in connection with scientific dishonesty is, first and foremost, to organise a system suitable for investigating cases effectively, professionally, and with proper respect to the fundamental legal rights of the parties involved. The Committee has also spent much effort in determining what can be termed scientific dishonesty and what falls outside this category but which may, nevertheless, be characterised as breaching of good scientific practice. It is emphasised that these rules are not arbitrarily established by the Committee, but formulated in accordance with norms general accepted by opinion leaders in the scientific community. An carlier version of this paper was presented at a symposium, Scientific Misconduct. An International Perspective, organised by The Medical University of Warsaw, 16 November, 1998. The article is based on more comprehensive articles by the same author in DCSD’s Annual Reports for 1993 and 1995.     

The emotional costs of parents' conditional regard: a self-determination theory analysis

Parents' use of conditional regard as a socializing practice was hypothesized to predict their children's introjected internalization (indexed by a sense of internal compulsion), resentment toward parents, and ill-being. In Study 1, involving three generations, mothers' reports of their parents' having used conditional regard to promote academic achievement predicted (a) the mothers' poor well-being and controlling parenting attitudes, and (b) their college-aged daughters' viewing them as having used conditional regard, thus showing both negative affective consequences from and intergenerational transmission of conditional regard. Study 2 expanded on the first by using four domains, including both genders, and examining mediating processes. College students' perceptions of their mothers' and fathers' having used conditional regard in four domains (emotion control, prosocial, academic, sport) were found to relate to introjected internalization, behavioral enactment, fluctuations in self-esteem, perceived parental disapproval, and resentment of parents. Introjection mediated the link from conditional regard to behavioral enactment. The results suggest that use of conditional regard as a socializing practice can promote enactment of the desired behaviors but does so with significant affective costs.     

Analysis of the decision-making process leading to appendectomy: a grounded theory study

The aim was to develop a theoretical understanding of the decision-making process leading to appendectomy. A qualitative interview study was performed in the grounded theory tradition using the constant comparative method to analyze data. The study setting was one county hospital and two local hospitals in Sweden, where 11 surgeons and 15 surgical nurses were interviewed. A model was developed which suggests that surgeons' decision making regarding appendectomy is formed by the interplay between their medical assessment of the patient's condition and a set of contextual characteristics. The latter consist of three interacting factors: (1) organizational conditions, (2) the professional actors' individual characteristics and interaction, and (3) the personal characteristics of the patient and his or her family or relatives. In case the outcome of medical assessment is ambiguous, the risk evaluation and final decision will be influenced by an interaction of the contextual characteristics. It was concluded that, compared to existing, rational models of decision making, the model presented identified potentially important contextual characteristics and an outline on when they come into play.     

The cognitive substrate of subjective probability

The prominent cognitive theories of probability judgment were primarily developed to explain cognitive biases rather than to account for the cognitive processes in probability judgment. In this article the authors compare 3 major theories of the processes and representations in probability judgment: the representativeness heuristic, implemented as prototype similarity, relative likelihood, or evidential support accumulation (ESAM; D. J. Koehler, C. M. White, & R. Grondin, 2003); cue-based relative frequency; and exemplar memory, implemented by probabilities from exemplars (PROBEX; P. Juslin & M. Persson, 2002). Three experiments with different task structures consistently demonstrate that exemplar memory is the best account of the data whereas the results are inconsistent with extant formulations of the representativeness heuristic and cue-based relative frequency.     

Using artificial life to teach evolutionary biology

This paper presents a pilot study on the use of artificial life software in an educational setting. Two groups of high school students received a standard lesson in evolutionary biology followed by a software session. The experimental group used the suite of artificial life software presented in this paper; the control group used a commercial multimedia hypertext. At the end of the software session both groups were asked to fill in a simple multiple-choice questionnaire testing the students knowledge of various aspects of evolutionary biology. The results show that the group using the artificial life software performed significantly better than the control group. We argue that the experimental group may learn more effectively because the artificial life makes it possible for students to perform experiments, a possibility not available to the control group.

Effects of the presence of others on food intake: a normative interpretation

The authors review the effect of the presence of others on food intake. In social facilitation studies, people tend to eat more in groups than when alone. In modeling studies, the presence of others may facilitate or inhibit intake, depending on how much these other people eat. Studies of impression management demonstrate that people tend to eat less in the presence of others than when alone. The authors attempt to reconcile these divergent literatures by reference to a model of inhibitory norms that govern eating. In the presence of palatable food, and in the absence of clear signals of satiety, people look outward to cues from the environment to determine when to stop eating. Socially derived inhibitory norms can account for either increased or decreased intake in the presence of others, depending on how much the others eat and the extent to which one is eager to impress them.     

Psychometric analysis of the Revised Memory and Behavior Problems Checklist: factor structure of occurrence and reaction ratings

A modified version of the Revised Memory and Behavior Problems Checklist (RMBPC; L. Teri et al., 1992) was administered across 6 different sites to 1,229 family caregivers of community-dwelling adults with dementia. The total sample was divided randomly into 2 subsamples. Principal components analyses on occurrence responses and reaction ratings from the first subsample resulted in a 3-factor solution that closely resembled the originally proposed dimensions (memory-related problems, disruptive behaviors, and depression). Confirmatory factor analyses on data from the second subsample indicated adequate fit for the 3-factor model. Correlations with other caregiver and care-recipient measures supported the convergent and discriminant validity of the RMBPC measures. In addition, female caregivers and White caregivers reported more problems, on average, than male caregivers and African American caregivers, respectively.     

The Revised Memory and Behavior Problems Checklist--Nursing Home: instrument development and measurement of burden among certified nursing assistants

Confirmatory factor analysis of the Revised Memory and Behavior Problems Checklist--Nursing Home (RMBPC) replicated the factor structure of the community-based RMBPC (L. Teri et al., 1992). The reliability of the total score was high as indexed by estimates of internal consistency (alpha = .95), test-retest reliability (r = .86), and interrater reliability between 2 interviewers (r = .88). Notably, the interrater reliability between 2 independent certified nursing assistants (CNAs) regarding residents' behavior problem frequency was more modest (r = .46), possibly reflecting the degree to which resident behaviors capture individual CNA's attention. This may have implications for the interpretation of data from the Minimum Data Set. CNAs reported moderately severe burden associated with behavior problems in 47% of residents under their care.
