Generating and remembering passwords

A survey evaluating the generation and use of passwords revealed that students have 8.18 password uses. With 4.45 different passwords to cover these functions, the average password has 1.84 applications. Two thirds of passwords are designed around one's personal characteristics, with most of the remainder relating to relatives, friends or lovers. Proper names and birthdays are the primary information used in constructing passwords, accounting for about half of all password constructions. Almost all respondents reuse passwords, and about two thirds of password uses are duplications. Passwords have been forgotten by a third of respondents, and over half keep a written record of them. We found empirical confirmation of some ‘bad password practices’ discussed in the literature, and provide suggestions for password construction and use. Copyright © 2004 John Wiley & Sons, Ltd.     

Bridging the gap on Facebook: assessing intergroup contact and its effects for intergroup relations

In line with Allport's contact hypothesis, previous research showed that direct intergroup contact can reduce prejudices. However, establishing face-to-face contact is not always feasible. We postulate that Facebook-groups are a setting where direct and observed intergroup contact can develop, reducing prejudices and increasing mutual acceptance. Analyzing the comments of nine Facebook-groups with the destructive and constructive conflict scale, our results indicated that the expression of prejudices decreased and that of mutual acceptance increased over time, both for in- and outgroup members of the Facebook-groups. Only the expression of less prejudices, but not that of more mutual acceptance was predicted by intergroup contact. The influence of group-based motivations on the engagement in intergroup contact is discussed, and the overall findings are integrated in Steele and Brown's process model of media practices.     

Making sense of social research: how useful is the Hawthorne Effect?

‘The Hawthorne Effect’ is a phrase frequently employed in textbooks and other academic discourse. It appears to have been coined over 50 years ago and alludes to the outcome of research undertaken two decades earlier. This paper seeks to elucidate how the term ‘Hawthorne Effect’ has come to be used. A variety of texts will be presented to demonstrate the many different and often contradictory meanings ascribed to the term. A consideration of Guerin's review of research in social facilitation suggests the complexity of issues that seem to be involved in the use of the term ‘Hawthorne Effect’ is such that greater precision is required. Ultimately, we conclude, the term has no useful role in the discussion of research findings. Copyright © 2006 John Wiley & Sons, Ltd.     

Stress and smoking in adolescence: a test of directional hypotheses.

The authors conducted a comparative test of the hypotheses that (a) stress is an etiological factor for smoking and (b) cigarette smoking causes increases in stress (A. C. Parrott, 1999). Participants were a sample of 1,364 adolescents, initially surveyed at mean age 12.4 years and followed at 3 yearly intervals. Measures of negative affect, negative life events, and cigarette smoking were obtained at all 4 assessments. Latent growth modeling showed negative affect was related to increase in smoking over time; there was no path from initial smoking to change in negative affect. Comparable results were found for negative life events, with no evidence for reverse causation. Results are discussed with respect to theoretical models of nicotine effects and implications for prevention.     

CHILD LABOUR: AN UNDERDEVELOPED TOPIC IN PSYCHOLOGY

Certain issues concerning child labour are raised: Why do psychologists do so little research on children working, despite the fact that it is widespread? Does work harm the child's development or deprive the child of necessary opportunities for play? How should research on child labour be conducted?     

Health Beliefs and Intentions: Predictors of Return Compliance in a Tuberculosis Detection Drive1

A prospective design was employed to study the ability of various factors to predict return compliance in a tuberculosis detection drive. Five hundred fiftythree participants in the drive were asked to complete a questionnaire tapping their views of TB (based on the Health Belief Model) and their intentions to return for the recommended skin test reading. Behavioral intention was found to be an important predictor of return rates, and the inclusion of the HBM variables aided in the classification noncompliers. Practical and theoretical implications of these findings are discussed.     

Relationships between locus of control,health value,and preventive health behaviors among women

This study examines the relationships between locus of control expectancies, rated health value, and reported participation in preventive health behaviors among a healthy sample of undergraduate women. The prediction that participation in preventive health behaviors would be a joint function of an internal health-related locus of control belief and holding health in high value was not supported. Instead, individuals who valued their health reported participating in a greater number of health-enhancing behaviors compared to those who valued their health less. Respondents' scores on a health value scale in combination with their rated health status proved to be better predictors of health behaviors than their locus of control beliefs. Limitations of locus of control research with young, healthy individuals are discussed and further investigation into the utility and validity of health value scales is recommended.     

Epistemic Entitlement and Luck

The aim of this paper is to defend a novel characterization of epistemic luck. Helping myself to the notions of epistemic entitlement and adequate explanation, I propose that a true belief suffers from epistemic luck iff an adequate explanation of the fact that the belief acquired is true must appeal to propositions to which the subject herself is not epistemically entitled (in a sense to be made clear below). The burden of the argument is to show that there is a plausible construal of the notions of epistemic entitlement and adequate explanation on which the resulting characterization of epistemic luck, though admittedly programmatic, has several important virtues. It avoids difficulties which plague modal accounts of epistemic luck; it can explain the conflicting temptations one can feel in certain alleged cases of epistemic luck; it offers a novel account of the value of knowledge, without committing itself to any particular analysis of knowledge; and it illuminates the significance for epistemology of the phenomenon of epistemic luck itself.     

Temperament and adolescent substance use: an epigenetic approach to risk and protection

We outline an epigenetic approach to understanding the relation between simple dispositional characteristics and complex problem behaviors, with a focus on adolescent substance use. Epigenetic theory predicts that effects of temperament are mediated through self-control and risk-taking tendency, isomorphic attributes that are based in temperament but represent developmental elaborations of these characteristics. We describe how the research program has confirmed predictions from epigenetic theory, addressed additional questions embodied in the theory, and clarified the multiple pathways from temperament characteristics to life stress, social relationships, and motives for substance use. In a final section, we discuss implications for the study of problem behavior and psychopathology.
