The Nature and Disvalue of Injury

This paper explicates a conception of injury as right-violation, which allows us to distinguish between setbacks to interests that should, and should not, be the concern of theories of justice. It begins by introducing a hybrid theory of rights, grounded in (a) the mobilisation of our moral equality to (b) protect our most important interests, and shows how violations of rights are the concern of justice, while setbacks where one of the twin grounds of rights is defeated are not. It then looks more closely at the substantive moral components of injury, namely harm—damage to one’s interests—and wrong—disrespect for one’s moral equality. It argues that, on the hybrid conception of rights, harm and wrong are individually necessary and jointly sufficient components of injury, and the disvalue of neither is reducible to the other—in particular, it is a mistake to construe the disrespect identified by wrong as another damaged interest. Finally, it distinguishes between the public and private dimensions of harm and wrong, and makes some preliminary suggestions as to whether the remedy for these different dimensions should lie in criminal, distributive, or corrective justice.     

Patterns of Thinking in Militant Extremism

ABSTRACT— Recurrent features of the thinking pattern (or mind-set) of violent militant extremists are delineated, discussed, and related to previous research and theory. We examined extremist groups from a diverse range of continents, cultures, and political and religious orientations. We compared statements by (and, to some degree, statements about) these groups and formulated 16 themes common to the militant-extremist mind-set. Among these themes are perceptions of a crisis involving violations of posited sacred values, along with justifications for the use of violence to remediate such problems. There are indications that such themes are not infrequent in the general population. For example, research participants failed to strongly disassociate themselves from the sentiments and framings found in the fanatical items, which undercuts the notion that militant-extremist thinking represents bizarre ideation. Militant-extremist thinking appears to represent a major, aggressive form of fanaticism affected by both dispositional and situational factors. Key themes in this thinking pattern might fit together to construct a potentially compelling narrative, which may be a key part of the ideological appeal of salient militant-extremist groups.     

Perceptual learning on inspection time and motion perception

Perceptual learning on simple perceptual tasks is interpreted as plasticity of neuronal populations in the sensory cortex (M. Fahle & T. Poggio, 2002). The authors examined individual differences on perceptual learning for 2 tasks-inspection time (IT) and a motion direction discrimination task that was instantiated as random dot kinematograms. The authors' main questions were whether individual differences in perceptual learning were consistent across the 2 tasks and whether perceptual learning correlated with cognitive abilities test scores. In all, 56 young adults completed 16 threshold estimations on 1 of 2 orthogonal versions of each task. Then, the authors made 2 further threshold estimations for the untrained, orthogonal version. Participants also completed a battery of 6 cognitive abilities tests that measured fluid ability (Gf) and perceptual speed (Gs). Perceptual learning was demonstrated for both tasks, but the degree of learning across tasks was not characteristic of the individual. Learning on IT correlated with Gs (r = .35), but learning on the motion direction discrimination task was unrelated to cognitive ability. Correlations of IT with cognitive measures were stable over the training period. IT was correlated with both the motion direction discrimination task (r = -.39) and an unmasked line length judgment task (r = -.31). The authors concluded that perceptual learning on IT correlates with cognitive abilities test scores, that correlations of IT with cognitive abilities test scores are stable as task performance improves with practice, and that the IT task is psychologically complex.     

Well-being in parents of children with cancer: The impact of parental personality,coping, and the child's quality of life

The aim of the study was to investigate the impact of parental personality, coping, and the child's quality of life on the well-being of parents of children treated for cancer. The study included 99 parents (63 mothers and 36 fathers), 41 parents during child's intensive treatment, 23 parents whose child completed intensive treatment, and 25 parents of children who completed treatment at least five years ago. The results of multivariate study have confirmed the predictive role of parental personality (especially Neuroticism); emotion-focused coping styles, and the child's quality of life (especially physical functioning) on parental well-being. About 60% of the variance in parental well-being can be attributed to the predictors. Assessing parental personality functioning and coping styles can help us identify those parents who are less emotionally stable, more prone to emotionally focused coping styles, and most likely to experience poorer well-being. Improved assessment may contribute to the development of further psychological interventions.     

Religious support and psychological well-being: gender differences among religious Jewish Israelis

The moderating effect of gender on the relation between religious support and well-being was examined using 334 religious Jewish men and women in Israel. Specifically, social support, religious support (Religious Leader Support (RLS), Religious Community Support (RCS), and G-d Support (GS)), anxiety, and life satisfaction were assessed. All support measures were significantly associated with less anxiety and more life satisfaction. Hierarchical multiple regression analyses indicated that all three types of religious support were uniquely related to life satisfaction. For GS and RCS, this unique effect was also found regarding anxiety. As hypothesised, gender moderated the relations between religious support and well-being regarding both RLS and RCS. The relation with life satisfaction was stronger for women in comparison to men, and the reverse was true regarding anxiety. Surprisingly, no moderation by gender was found regarding GS. Findings are discussed regarding the importance of assessing gender in future religious support research.     

Teaching arbitrary matching via sample stimulus-control shaping to young children and mentally retarded individuals: a methodological note.

Two experiments demonstrated the efficacy of sample stimulus-control shaping programs for teaching arbitrary matching to 4 subjects who did not acquire the performances via standard methods (i.e., differential reinforcement and, in two cases, comparison intensity fading). All 4 had previously demonstrated identity matching with two-dimensional forms. Identity matching performances were then transformed into arbitrary matching by gradually changing the sample stimuli until they no longer resembled the comparison stimuli. Where applicable, these methods may have advantages over others that have been used after the failure of standard techniques.     

Stress, Glucocorticoids, and Damage to the Nervous System: The Current State of Confusion

An extensive literature demonstrates that glucocorticoids (GCs), the adrenal steroids secreted during stress, can have a broad range of deleterious effects in the brain. The actions occur predominately, but not exclusively, in the hippocampus, a structure rich in corticosteroid receptors and particularly sensitive to GCs. The first half of this review considers three types of GC effects: a) GC-induced atrophy, in which a few weeks' exposure to high GC concentrations or to stress causes reversible atrophy of dendritic processes in the hippocampus; b) GC neurotoxicity where, over the course of months, GC exposure kills hippocampal neurons; c) GC neuroendangerment, in which elevated GC concentrations at the time of a neurological insult such as a stroke or seizure impairs the ability of neurons to survive the insult. The second half considers the rather confusing literature as to the possible mechanisms underlying these deleterious GC actions. Five broad themes are discerned: a) that GCs induce a metabolic vulnerability in neurons due to inhibition of glucose uptake; b) that GCs exacerbate various steps in a damaging cascade of glutamate excess, calcium mobilization and oxygen radical generation. In a review a number of years ago, I concluded that these two components accounted for the deleterious GC effects. Specifically, the energetic vulnerability induced by GCs left neurons metabolically compromised, and less able to carry out the costly task of containing glutamate, calcium and oxygen radicals. More recent work has shown this conclusion to be simplistic, and GC actions are shown to probably involve at least three additional components: c) that GCs impair a variety of neuronal defenses against neurologic insults; d) that GCs disrupt the mobilization of neurotrophins; e) that GCs have a variety of electrophysiological effects which can damage neurons. The relevance of each of those mechanisms to GC-induced atrophy, neurotoxicity and neuroendangerment is considered, as are the likely interactions among them.
