Natural Selection and Design: Comments on Michael Ruse's New Book

Is the adaptive complexity of living organisms the result of evolutionary processes alone? or does it give evidence of intentional design? Michael Ruse appears to argue that we can have it either way. As a scientist I find the argument from design unnecessary. Yet it has great appeal to humans, whose behavior is largely intentional and who look for patterns in events and for the intentions that may have produced them.     

Messages about sex in the workplace: A content analysis of primetime television

Because television has the potential to shape cultural beliefs about both sexual norms and appropriate workplace behavior, it seems important to examine TV’s portrayal of “sexual etiquette” in the workplace. In a content analysis of two episodes of every primetime comedy aired on all broadcast and cable networks during fall 2000, we coded every sexual remark and behavior made in a workplace scene. Across all networks, 85 percent of programs and one in four workplace interactions contained some type of sexual content. Overall, a viewer is likely to hear eleven sexual remarks and see two to three sexual behaviors in a workplace setting per hour; this jumps to twenty-three remarks and nine behaviors on cable networks. Sexual remarks were mostly explicit, made in an office setting, by White men, and were rarely (1.4%) about sexual harassment or discrimination. Although sexual content in the workplace was generally less common on broadcast than cable networks, a broadcast network (Fox) actually had the highest overall rate, with sexual content in 38 percent of workplace scenes. Given that research suggests that TV teaches youth about sexuality and cultivates sexual attitudes and beliefs consistent with televised portrayals, it is alarming that youth may learn from television that sex in the workplace is not only commonplace, but also to be tolerated and enjoyed.     

Identity,Perceived Religious Discrimination,and Psychological Well‐Being in Muslim Immigrant Women

The study investigated perceived religious discrimination and three facets of Muslim identity (psychological, behavioural, and visible) as predictors of psychological well‐being (life satisfaction and psychological symptoms) of 153 Muslim women in New Zealand. The results indicated that although visibility (wearing hijab) was associated with greater perceived discrimination, it predicted positive psychological outcomes. Analysis further revealed that the psychological (pride, belongingness, and centrality) and behavioural (engaging in Islamic practices) facets of Muslim identity moderated the relationship between perceived religious discrimination and well‐being. A strong psychological affiliation with Islam exacerbated the negative relationship between perceived religious discrimination and well‐being. Conversely, engaging in Islamic practices buffered the negative impact of discrimination. The research highlights the complexity of Muslim identity in diasporic women.     

Age and Trust as Moderators in the Relation between Procedural Justice and Turnover: A Large‐Scale Longitudinal Study

The current study investigated the moderating roles of age and trust in the relation of procedural justice with turnover. It was expected that the relation between procedural justice and turnover was weaker for older workers and those with high prior trust in their leader. Older workers are better at regulating their emotions, and focus more on positive aspects of their relationships with others, and therefore react less intensely to unfair treatment. Moreover, people with high trust are more likely to attribute unfair treatment to circumstances instead of deliberate intention than people with low trust. Finally, we expected a three‐way interaction between age, trust, and procedural justice in relation to turnover, where older workers with high trust would have less strong reactions than younger workers and older workers with low trust. Results from a three‐wave longitudinal survey among 1,597 Dutch employees indeed revealed significant interactions between trust and procedural justice in relation to turnover. Furthermore, the three‐way interaction was significant, with negative relations for younger workers, but a non‐significant relation was found for older workers with low trust. Contrary to expectations, negative relations were found between procedural justice and turnover for older workers with high trust.     

Planning and Problem solving Using the Five disc Tower of London Task

This paper investigates the planning and problem-solving abilities of normal adult subjects using a complex version of Shallice's (1982, 1988) Tower of London (TOL) task. Subjects were required to plan a fluent solution to a range of 5-disc TOL puzzles and then execute their formulated plans as fast as possible. The number of errors and the times taken to prepare the most efficient solutions increased monotonically with the number of chunks of subgoal moves. A subgoal move is a move that is essential for the solution of the puzzle, but which does not place a disc into its goal position. A subgoal chunk is a consecutive series of subgoal moves that all transfer discs to and from the same pegs. Furthermore, preparation time was found to be sensitive to a manipulation that increased the number of competing alternative choices, at critical steps in move selection. When subjects planned their action sequences 'on-line', analyses of individual moves and individual move latencies suggested that planning TOL solutions was limited by the difficulty in evaluating and selecting one action (or one subgoal chunk) from the set of competing potential actions at each step in the course of problem solving.
