Safe and Unsafe Sexual Intentions and Behavior: The Effects of Norms and Attitudes1

A study of 85 heterosexual men, 85 heterosexual women, and 82 homosexual men was undertaken to examine the variables that influence intentions to engage in different sexual practices and actual sexual behavior. On the basis of Fishbein and Ajzen's (1975) theory of reasoned action, it was predicted that the strength of intentions would be related to whether behavior was in accord with intentions. Consistent with expectations, the strength of intention to engage in six different sexual practices (e. g., vaginal intercourse, anal intercourse, oral sex) and the three strategies that modify the risk of HIV transmission (sex with an exclusive partner, sex wearing a condom, and looking for a new partner) predicted actual behavior. Second, it was proposed that attitudes toward one's sexual practices and norms would be related to intentions to engage in safe sex. To reflect differential levels in the safety of behavioral intentions, five safety intention groups were formed: (a) nonpenetrative sex, (b) penetrative sex in an exclusive relationship with a condom, (c) penetrative sex in an exclusive relationship without a condom, (d) penetrative sex in a nonexclusive relationship with a condom, and (e) penetrative sex in a nonexclusive relationship without a condom. Norms, rather than attitudes, distinguished the five safety intention groups. the groups intending to engage in safe sex (nonpenetrative sex or penetrative sex with a condom) perceived lower levels of social approval for their sexual practices than the noncondom groups. Additional analyses showed that past behavior had a stabilizing effect on the intention-behavior relationship, but only for the nonpenetrative and noncondom safety intention groups.

Children's Developing Understanding of Place Value: Semiotic Aspects

This article is devoted to two interrelated semiotic aspects of the placevalue system: multiplicity of value and composition of values. Both aspects involve the basic characteristic of the placevalue system-the differentiation between face value and complete value. We explored whether a system that is intermediate between the written place-value system (multiplicity of value) and the base-10 manipulatives (no multiplicity of value) helps children understand the place-value system. The intermediate system that we designed, called FVCV (for face value and complete value), has a pseudomultiplicity of value. We report and discuss evidence that instruction and practice in the FVCV system helped children (a) to differentiate between the face value and the complete value of the digits in a multidigit place-value number representation and (b) to grasp that the complete values of the digits in a multidigit placevalue number representation add up to the total value.     

Exploring the Public Understanding of Basic Genetic Concepts

It is predicted that the rapid acquisition of new genetic knowledge and related applications during the next decade will have significant implications for virtually all members of society. Currently, most people get exposed to information about genes and genetics only through stories publicized in the media. We sought to understand how individuals in the general population used and understood the concepts of “genetics” and “genes.” During in-depth one-on-one telephone interviews with adults in the United States, we asked questions exploring their basic understanding of these terms, as well as their belief as to the location of genes in the human body. A wide range of responses was received. Despite conversational familiarity with genetic terminology, many noted frustration or were hesitant when trying to answer these questions. In addition, some responses reflected a lack of understanding about basic genetic science that may have significant implications for broader public education measures in genetic literacy, genetic counseling, public health practices, and even routine health care.     

Safety in Occupational Driving: Development of a Driver Behavior Scale for the Workplace Context

International statistics indicate that occupational, or work‐related driving, crashes are the most common cause of workplace injury, death, and absence from work. The majority of research examining unsafe driver behavior in the workplace has relied on general road safety questionnaires. However, past research has failed to consider the organisational context in the use of these questionnaires, and thus, there is ambiguity in the dimensions constituting occupational driving. Using a theoretical model developed by Hockey (1993, 1997 ), this article proposes and validates a new scale of occupational driver behavior. This scale incorporates four dimensions of driver behavior that are influenced by demanding workplace conditions: speeding, rule violation, inattention, and driving while tired. Following a content validation process, three samples of occupational drivers in Australia were used to assess the scale. Data from the first sample (n= 145) were used to reduce the number of scale items and provide an assessment of the factorial validity of the scale. Data from the second sample (n= 645) were then used to confirm the factor structure and psychometric properties of the scale including reliability and construct validity. Finally, data from the third sample (n= 248) were used to establish criterion validity. The results indicated that the scale is a reliable and valid measure of occupational driver behavior.     

Making Their Own Connections: Students' Understanding of Multiple Models in Basic Electricity

In this study we explore the educational impact of teaching high school students several models of the same phenomenon. In particular, we create different sets of models of static electricity (each set containing 1 model of particles and 1 model of aggregates of particles) that are connected in specific ways and measure the effects of these links on further learning of circuit behavior. Four groups were run through a 2-week curriculum on direct current electricity. One group received "coordinated" models that are connected together by their mechanisms and representations. Another group received "noncoordinated" models that do not connect via mechanisms and representations. The other two groups served as control groups for the Coordinated and Noncoordinated conditions. Contrary to the hypothesis that Coordinated models would be easier to learn and apply, posttest results show that students in the Noncoordinated condition outperformed those in their control group; meanwhile, the Coordinated group did not outperform its control group on these tests. An analysis of process data gathered while students were working through the curriculum suggests that students in the Noncoordinated group were actively combining the different models presented in that treatment condition. We conjecture that the effort of trying to achieve coherence among models may have led to a better understanding as measured by the posttests.     

Scientific Progress,Understanding, and Knowledge: Reply to Park

Dellsén (2016) has recently argued for an understanding-based account of scientific progress, the noetic account, according to which science (or a particular scientific discipline) makes cognitive progress precisely when it increases our understanding of some aspect of the world. I contrast this account with Bird’s (2007, 2015); epistemic account, according to which such progress is made precisely when our knowledge of the world is increased or accumulated. In a recent paper, Park (2017) criticizes various aspects of my account and his arguments in favor of the noetic account as against Bird’s epistemic account. This paper responds to Park’s objections. An important upshot of the paper is that we should distinguish between episodes that constitute and promote scientific progress, and evaluate account of scientific progress in terms of how they classify different episodes with respect to these categories.     

A Comparison of the SVIB Basic Interest Scales with the Regular Occupational Scales

The purpose of this study was to determine whether the recently developed Basic Scales for the SVIB would provide more generalizable and psychologically meaningful information than the regular SVIB Occupational Scales. Four groups of students were used, two entering contrasting four-year curricula (Science, N-282, vs Non-Science, N = 142) and two entering contrasting two-year curricula (Art, N = 45 vs Technical, N = 62). Basic and regular SVIB scale means were calculated for each group. Those scales with large (approximately one-half a standard deviation or more) and statistically significant differences were identified for both the four-year and the two-year group comparisons.

Prediction of Behaviour vs. Prediction of Behaviour Change: The Role of Motivational Moderators in the Theory of Planned Behaviour

Research has identified moderating variables of the cognition–behaviour relationship in the Theory of Planned Behaviour (TPB). These include intention certainty, affective–cognitive congruence of attitudes, attitudinal ambivalence, and past behaviour. It has not yet been systematically tested if these moderators apply in similar ways to the prediction of behaviour and behaviour change (when past behaviour is controlled). A sample of 1,418 university students completed measures of the direct predictors of the TPB (perceived behavioural control; PBC and intention), intention certainty, affective–cognitive congruence of attitudes, attitudinal ambivalence, and the Godin Leisure Time Physical Exercise Questionnaire at the beginning of the academic year and two months later. Data were analysed using moderated hierarchical linear regressions. Without controlling for baseline behaviour, intention certainty and affective–cognitive congruence moderated both the intention–behaviour and PBC–behaviour relationships and showed additional main effects. Attitudinal ambivalence did not contribute to the prediction. When past behaviour was controlled, the main effects were attenuated and only the intention certainty* PBC interaction remained significant. Predictors of behaviour do not necessarily predict behaviour change. The TPB-related moderators studied here weakly contributed to the prediction of behaviour change. Proposals for increasing the predictive power of TPB for behaviour change are discussed.     

Religion in the Treaty of Lisbon: Aspects and Evaluation

Religion is now firmly present in the Treaty of Lisbon. This article analyses whether the presence of religion in this Treaty is a reflection of the religious component of European identity and the successful campaign of the Christian churches. I compare the initial objectives of the churches with the results achieved and pay attention to the identity-related debates which took place when the provision for religion was elaborated and discussed. Although one cannot claim that the churches fully achieved their initial goals, it should be taken into account that they acted in a situation of strong secular resistance. Therefore, the text of the Treaty of Lisbon reflects the struggle between religious and secular actors; however, generally speaking, it provided better opportunities for the churches to exercise their influence on the supra-national European level and confirmed the strong presence of the religious component in European identity.

Personality and Work Behaviour: Exploring the Linkages

Une étude du rapport personnalité et conduites de travail requiert la prudence dans la considération des liaisons critiques dans les modèles théoriques et dans les plans de recherche utilisés et la personnalité et les construits de critère proposés en théorie et en recherche. La valeur de la considération de ces liaisons est illustrée par des exemples de la littérature en pointe sur la personnalité et les conduites de travail.
The more productive study of the relationship of personality to work behaviour requires thoughtful consideration of critical linkages in the theoretical models and research designs used, and the personality and criterion constructs incorporated in theory and research. The value of considering these linkages is illustrated by examples from the emerging literature on personality and work behaviour.     

Happiness in Behaviour Genetics: Findings and Implications

A number of behaviour genetic studies have shown variation in happiness to be influenced by genes, and indicated that long-term happiness is predominantly caused by genes. To policy makers and individuals, as well as the psychological and psychiatric enterprise, evidence for considerable and stable genetic contributions suggests that societal changes, therapeutic interventions, and public prevention may produce mainly transitory or minor effects. This is not true. The present paper aims to summarise the recent behaviour genetic findings on happiness and happiness-related constructs and to discuss their theoretical and practical implications. Specifically, five major implications relevant to public health work, are outlined and broadly discussed: (1) high heritability does not limit chances for raising happiness, (2) genes generate stability, (3) environments generate change, (4) environmental influences operate on an individual-by-individual basis, and (5) control for genetic endowments is necessary for correct measures of environmental effects.     

Suicide in the Subway: Psychodynamic Aspects*

ABSTRACT: Fifty-one cases of suicide attempts in the subway have been investigated to examine the question of whether the method used has psychodynamic significance or is merely adventitious. We found that no single characteristic distinguished subway suicide from all other suicide modalities, although as a group the subway cases had a higher proportion of psychotic and previously suicidal patients than other series quoted in the literature. However, there were important differences between subway suicide cases seeking a “traumatic” death (jumping in front of a train; lying across the track awaiting destruction) and those seeking a “nontraumatic” death (electrocution on the live “third rail”). The traumatic group had histories of exposure to violence, other traumatic suicide attempts, hostile or destructive delusions, and many “destroy” words on psychological test protocols. The smaller nontraumatic group had no such history of exposure to violence; their previous suicide attempts were nontraumatic; delusions, when present, were not menacing; and the psychological tests showed more “escape” words than “destroy” words.     

Challenges in the Evaluation of Nanoscale Research: Ethical Aspects

The purpose of the present paper is: (1) to outline a conceptual framework useful for the analysis of ethical issues raised by goal-directed activities, (2) to apply this framework to nanoscale research, (3) identify some of the main challenges in the evaluation of such research, and (4) exemplify what is needed for a positive answer to the question “How can nanoscale research improve the quality of life?” A basic idea of the paper is that nanoscale research can improve the conditions and quality of life of large groups in society, provided that: (a) this research is directed at certain generally accepted goals, (b) at least some of the opportunities are exploited for the good of mankind, (c) the key obstacles on the road are eliminated, reduced or circumvented, and (d) this is done in ethically acceptable ways.
