Buffers or Boosters? The Role of HRM Practices in Older Workers' Experience of Stereotype Threat

Building on the social identity approach and the HRM literature, this two-wave cross-sectional study examined the effects of negative age-based metastereotypes on the age-based stereotype threat experience of older workers and on organizational disidentification. The moderator role of HRM practices in the relationship between negative age-based metastereotypes and age-based stereotype threat was also investigated. Older workers survey results (n = 469) from 14 manufacturing companies indicated that negative age-based metastereotypes correlate positively with stereotype threat. Moderation results showed that age-awareness HRM practices (training for older workers) reinforced age-based stereotype threat, whereas general HRM practices (recognition and respect) impaired it. The article suggests that the combination of age-based metastereotypes with a stereotype threat framework contributes to further understand older workers' beliefs and attitudes. It also indicates that to be effective, HRM practices should emphasize positive social identities older workers share with their colleagues, rather than giving older workers special treatment that may, after all, reinforce stigmatization.     

Paul Tillich's Realistic Stance Toward the Vital Trends of Nature

Many scientists have argued forcefully for the pointlessness of nature, something that challenges any doctrine of Creation. However, apparent design and comprehensibility are also to be found in nature; it is ambivalent. This trait is nowhere more evident than in the natural inclinations that lead to concupiscence and the "seven deadly sins" in human beings. These inclinations are dealt with as pertaining to the "pre-fallen" condition of nature and human beings. As a framework to make sense of the goodness of creation in this context, Paul Tillich's notion of the "vital trends of nature" is called to the fore. Being at the intersection of a philosophy of religion and a philosophy of nature, this notion hints at the goodness of Creation in fragment and anticipation.     

Changing Drug Users’ Risk Environments: Peer Health Advocates as Multi-level Community Change Agents

Peer delivered, social oriented HIV prevention intervention designs are increasingly popular for addressing broader contexts of health risk beyond a focus on individual factors. Such interventions have the potential to affect multiple social levels of risk and change, including at the individual, network, and community levels, and reflect social ecological principles of interaction across social levels over time. The iterative and feedback dynamic generated by this multi-level effect increases the likelihood for sustained health improvement initiated by those trained to deliver the peer intervention. The Risk Avoidance Partnership (RAP), conducted with heroin and cocaine/crack users in Hartford, Connecticut, exemplified this intervention design and illustrated the multi-level effect on drug users’ risk and harm reduction at the individual level, the social network level, and the larger community level. Implications of the RAP program for designing effective prevention programs and for analyzing long-term change to reduce HIV transmission among high-risk groups are discussed from this ecological and multi-level intervention perspective.     

Means to an end: Neotropical parrots manage to pull strings to meet their goals

Although parrots share with corvids and primates many of the traits believed to be associated with advanced cognitive processing, knowledge of parrot cognition is still limited to a few species, none of which are Neotropical. Here we examine the ability of three Neotropical parrot species (Blue-Fronted Amazons, Hyacinth and Lear’s macaws) to spontaneously solve a novel physical problem: the string-pulling test. The ability to pull up a string to obtain out-of-reach food has been often considered a cognitively complex task, as it requires the use of a sequence of actions never previously assembled, along with the ability to continuously monitor string, food and certain body movements. We presented subjects with pulling tasks where we varied the spatial relationship between the strings, the presence of a reward and the physical contact between the string and reward to determine whether (1) string-pulling is goal-oriented in these parrots, (2) whether the string is recognized as a means to obtain the reward and (3) whether subjects can visually determine the continuity between the string and the reward, selecting only those strings for which no physical gaps between string and reward were present. Our results show that some individuals of all species were able to use the string as a means to reach a specific goal, in this case, the retrieval of the food treat. Also, subjects from both macaw species were able to visually determine the presence of physical continuity between the string and reward, making their choices consistently with the recognition that no gaps should be present between the string and the reward. Our findings highlight the potential of this taxonomic group for the understanding of the underpinnings of cognition in evolutionarily distant groups such as birds and primates.     

Kicking the (barking) dog effect: the moderating role of target attributes on triggered displaced aggression

Sometimes aggression is displaced onto a target who is not totally innocent but emits a mildly irritating behavior called a triggering event. In three experiments, the authors examine stable personal attributes of targets that can impact such triggered displaced aggression (TDA). Lower levels of TDA were directed to targets whose attitudes were similar as compared to dissimilar to those of the actor (Experiment 1) and to targets who were ingroup as compared to out-group members (Experiment 2). Conceptually replicating the findings of Experiments 1 and 2, the manipulated valence of the target (viz., liked, neutral, and disliked) functioned in a similar manner, with positive valence serving a buffering function against a triggering action that followed an initial provocation (Experiment 3). The results from all three experiments are consistent with cognitive neoassociationist theory.     

Neural and cognitive plasticity: from maps to minds

Some species and individuals are able to learn cognitive skills more flexibly than others. Learning experiences and cortical function are known to contribute to such differences, but the specific factors that determine an organism's intellectual capacities remain unclear. Here, an integrative framework is presented suggesting that variability in cognitive plasticity reflects neural constraints on the precision and extent of an organism's stimulus representations. Specifically, it is hypothesized that cognitive plasticity depends on the number and diversity of cortical modules that an organism has available as well as the brain's capacity to flexibly reconfigure and customize networks of these modules. The author relates this framework to past proposals on the neural mechanisms of intelligence, including (a) the relationship between brain size and intellectual capacity; (b) the role of prefrontal cortex in cognitive control and the maintenance of stimulus representations; and (c) the impact of neural plasticity and efficiency on the acquisition and performance of cognitive skills. The proposed framework provides a unified account of variability in cognitive plasticity as a function of species, age, and individual, and it makes specific predictions about how manipulations of cortical structure and function will impact intellectual capacity.     

Personalization and differentiation as moderators of triggered displaced aggression towards out‐group targets

Two studies examined the reduction of triggered displaced aggression (TDA) via bottom‐up processing modes of de‐categorization. Participants were provoked by the experimenter and then interacted with an ostensible out‐group member who either did or did not provide a second (triggering) provocation. Study 1 compared TDA toward a triggering out‐group member who had previously been either differentiated from the out‐group, made the focus of self‐other comparison, or was in a no‐information control condition. As predicted, both differentiation and self‐other comparison reduced aggression relative to the control condition. Study 2 examined the effect of negative self‐disclosure from the out‐group target, and contrasted its effects with both self‐other comparison with a negative other, and a no‐information control condition. As predicted, triggered participants in the negative self‐disclosure condition aggressed less than those triggered in the negative self‐other comparison or no‐information control conditions. The liking induced by self‐disclosure mediated its aggression‐reducing effect. Copyright © 2006 John Wiley & Sons, Ltd.     

Differential evaluation of residential care programmes for minors

In this study, the results achieved by residential care programs for minors were evaluated. Two measurements were taken, nine months apart, from a total of 175 minors using a monthly observation scale of goals from an Individualised Educational Project. It was found that, in the majority of the dimensions analysed, there were improvements, although they were not the same for all the minors or of the same magnitude. The differential analyses show that variables such as reason for admission and duration of stay modify the results obtained. There was no significant relationship with age or sex. These results are discussed in the light of existing literature.
