The job involvement modulating role in the relationship between stress and job satisfaction

This paper analyzes the modulator role of job involvement in the relationship between stress and job satisfaction, using the OSI (Occupational Stress Indicator) model. For this purpose, we analyzed: six sources of stress, the OSI job satisfaction results, and a job involvement scale. The sample consisted of 779 professional soldiers from the Spanish Army. The results show that when the levels of the two dimensions job involvement (psychological identification and job-related feelings of duty-obligation are high, stress due to achievements and career development and social relationships will have no influence on job satisfaction. However, we found higher job satisfaction, even when stress is high, in those situations where psychological identification is low and job-related feelings of duty-obligation are high.     

‘How Can I Feel for Others When I Myself Am Beaten?’ The Impact of the Armed Conflict on Women in Israel

This research presents an initial documentation of Israeli women’s sense of insecurity during the Second Intifada (2001–2005). Drawing on feminist security theory and the intersectional approach to gender, we hypothesized that women’s familiar tendency to develop high levels of stress following political violence would be related to previous sexual and domestic victimization, to economic distress and ethnic discrimination among minority women, and to the cultural role of care workers among women of all socio-economic backgrounds. A sample of 552 women self-completed a cluster of questionnaires addressing a broad array of topics, and results confirmed most of the research hypotheses. The discussion highlights the multiple articulations of gender, militarism, and security and their possible implications for policies of conflict resolution.     

Cholinergic activity in the insular cortex is necessary for acquisition and consolidation of contextual memory

Experiences with a high emotional content (aversive) tend to be stored as long-term memories; however, there are also contextual recollections, which form a significant part of our memories. Different research has shown that the insular cortex (IC) plays an important role during aversive memory formation, yet its role during incidental/non-aversive learning like pre-exposure contextual memory formation has received little attention. The objective of this research was to establish the role of cholinergic activity in the IC through its muscarinic receptors during the formation of inhibitory avoidance (IA) memory, as well as during pre-exposure contextual memory, using a paradigm such as latent inhibition (LI). Rats with bilateral cannulae directed into the IC were trained in the LI paradigm of IA or IA task alone. The muscarinic antagonist receptor scopolamine was infused bilaterally into the IC 5 min before the pre-exposure into the dark chamber of the IA cage, one day before the conventional IA training or during the IA training day. During the IA test, the entrance latency into the dark chamber of the IA cage was measured as an index of contextual memory. The results showed that scopolamine infused before and after IA training disrupts inhibitory avoidance memory. Also, it showed that the pre-exposed saline-infused animals (LI) had a lower entrance latency compared to the group not pre-exposed (IA). However, the group that received scopolamine into the IC before, but not after, the pre-exposure to the dark chamber, presented a similar latency to the IA group, showing a blockade of the latent inhibition of the IA. These results suggest that cholinergic activity in the insular cortex is necessary during the acquisition and consolidation of avoidance memory, but appears necessary only during the acquisition of pre-exposure non-aversive contextual memory.     

Electrical stimulation of the pedunculopontine tegmental nucleus in freely moving awake rats: time- and site-specific effects on two-way active avoidance conditioning

The pedunculopontine tegmental nucleus (PPTg) is involved in the regulation of thalamocortical transmission and of several functions related to ventral and dorsal striatal circuits. Stimulation of the PPTg in anesthetized animals increases cortical arousal, cortical acetylcholine release, bursting activity of mesopontine dopaminergic cells, and striatal dopamine release. It was hypothetized that PPTg stimulation could improve learning by enhancing cortical arousal and optimizing the activity of striatal circuits. We tested whether electrical stimulation (ES) of the PPTg, applied to freely-moving awake rats previously implanted with a chronic electrode, would improve the acquisition and/or the retention of two-way active avoidance conditioning, and whether this effect would depend on the specific PPTg region stimulated (anterior vs posterior) and on the time of ES: just before (pre-training) or after (post-training) each of three training sessions. The treatment consisted of 20 min of ES (0.2 ms pulses at 100 Hz; current intensity: 40-80 microA). The results showed that (1) this stimulation did not induce either any signs of distress nor abnormal behaviors, apart from some motor stereotyped behaviors that disappeared when current intensity was lowered; (2) pre-training ES applied to the anterior PPTg improved the acquisition of two-way active avoidance, (3) no learning improvement was found after either post-training ES of the anterior PPTg, or pre- and post-training ES of the posterior PPTg. The results give support to a role of PPTg in learning-related processes, and point to the existence of functional PPTg regions.     

Thinking Without Words: An Overview for Animal Ethics

In Thinking without Words I develop a philosophical framework for treating some animals and human infants as genuine thinkers. This paper outlines the aspects of this account that are most relevant to those working in animal ethics. There is a range of different levels of cognitive sophistication in different animal species, in addition to limits to the types of thought available to non-linguistic creatures, and it may be important for animal ethicists to take this into account in exploring issues of moral significance and the obligations that we might or might not have to non-human animals. I am grateful for comments on an earlier version from Robert Francescotti and Clare Palmer.

Weight as an Embodiment of Importance

ABSTRACT— Four studies show that the abstract concept of importance is grounded in bodily experiences of weight. Participants provided judgments of importance while they held either a heavy or a light clipboard. Holding a heavy clipboard increased judgments of monetary value (Study 1) and made participants consider fair decision-making procedures to be more important (Study 2). It also caused more elaborate thinking, as indicated by higher consistency between related judgments (Study 3) and by greater polarization of agreement ratings for strong versus weak arguments (Study 4). In line with an embodied perspective on cognition, these findings suggest that, much as weight makes people invest more physical effort in dealing with concrete objects, it also makes people invest more cognitive effort in dealing with abstract issues.     

Relativizing utterance-truth?

In recent years, some people have held that a radical relativist position is defensible in some philosophically interesting cases, including future contingents, predicates of personal taste, evaluative predicates in general, epistemic modals, and knowledge attributions. The position is frequently characterized as denying that utterance-truth is absolute. I argue that this characterization is inappropriate, as it requires a metaphysical substantive contention with which moderate views as such need not be committed. Before this, I also offer a more basic, admittedly less exciting alternative characterization of the position, in terms of departing from the Kaplan–Lewis–Stalnaker two-dimensional framework.     

FUNCTIONAL ANALYSIS AND TREATMENT OF SELF‐INJURY IN A CAPTIVE OLIVE BABOON

Self‐injurious behavior (SIB), such as self‐biting and head banging, has been reported to occur in approximately 10% of captive, individually housed nonhuman primates. Accounts of the etiology of SIB in primates range from ecological to physiological. However, to date, no research has examined the possible influence of social consequences delivered by handlers and keepers in the maintenance of SIB in this population. The current study investigated the effects of social contact as a potentially reinforcing consequence for the SIB displayed by an olive baboon (Papio hamadryas anubis). Results indicated that the behavior was maintained by attention from humans. As treatment, reinforcement was arranged for an appropriate alternative response, resulting in increases in the appropriate alternative behavior and decreases in SIB.
