Rethinking Sikh Nationalism in the Twenty-First Century

This article seeks to draw attention to some of the core issues which beset the study of Sikh nationalism as a coherent phenomenon in an increasingly globalized and socially fragmented world. First, it highlights the importance of revisiting the debate about the community's religious boundaries, arguing that in contrast to the new conventional wisdom informed by poststructuralism, Sikh identity has exhibited a remarkable degree of continuity from the establishment of the Khalsa in comparison with other South Asian religio-political communities. The second key issue highlighted is the role of the Sikh diaspora in the development of Sikh nationalism and statehood. It critically examines the extent to which diaspora may be regarded as an instrument of ‘long-distance’ nationalism. Third, it argues that the existing literature on Sikh nationalism is remarkably community-centric and needs to engage with theories of nationalism. Finally, while acknowledging the cleavages which fragment the Sikh nation, it concludes that Sikh nationalism has been remarkably cohesive.     

Impairment of executive functions in boys with attention deficit/hyperactivity disorder.

The main aim of the present study is to compare the efficiency of executive control processes in 24 boys with attention deficit/hyperactivity disorder (ADHD) and 58 normal controls of similar age (between 8 and 11 years). Three reaction time (RT) paradigms were utilized: a dual task that requires coordination of two tasks responses, a shift task that makes it necessary to disengage attention from one task and engage into another one, and a stimulus-response spatial compatibility task that requires participants to inhibit a prepotent response. Another purpose of the study is to examine whether Barkley's (1997) executive dysfunction or Sergeant et al.'s (1999) resource allocation/arousal model best account for the behavioral deficits associated with ADHD. Examination of raw RT data showed significantly poorer performance in ADHD children with respect to age-matched controls on both the higher-level cognitive functions of executive control and on lower-level abilities (e.g., speed of processing) of all tasks of this study. However, using proportional transformations of raw RT data, we could demonstrate that, in addition to differences in processing speed, also executive control processes were significantly impaired in children with ADHD.     

A simple neural network model of the hippocampus suggesting its pathfinding role in episodic memory retrieval

The goal of this work is to extend the theoretical understanding of the relationship between hippocampal spatial and memory functions to the level of neurophysiological mechanisms underlying spatial navigation and episodic memory retrieval. The proposed unifying theory describes both phenomena within a unique framework, as based on one and the same pathfinding function of the hippocampus. We propose a mechanism of reconstruction of the context of experience involving a search for a nearly shortest path in the space of remembered contexts. To analyze this concept in detail, we define a simple connectionist model consistent with available rodent and human neurophysiological data. Numerical study of the model begins with the spatial domain as a simple analogy for more complex phenomena. It is demonstrated how a nearly shortest path is quickly found in a familiar environment. We prove numerically that associative learning during sharp waves can account for the necessary properties of hippocampal place cells. Computational study of the model is extended to other cognitive paradigms, with the main focus on episodic memory retrieval. We show that the ability to find a correct path may be vital for successful retrieval. The model robustly exhibits the pathfinding capacity within a wide range of several factors, including its memory load (up to 30,000 abstract contexts), the number of episodes that become associated with potential target contexts, and the level of dynamical noise. We offer several testable critical predictions in both spatial and memory domains to validate the theory. Our results suggest that (1) the pathfinding function of the hippocampus, in addition to its associative and memory indexing functions, may be vital for retrieval of certain episodic memories, and (2) the hippocampal spatial navigation function could be a precursor of its memory function.     

Reorientation by geometric and landmark information in environments of different size

It has been found that disoriented children could use geometric information in combination with landmark information to reorient themselves in large but not in small experimental spaces. We tested domestic chicks in the same task and found that they were able to conjoin geometric and nongeometric (landmark) information to reorient themselves in both the large and the small space used. Moreover, chicks reoriented immediately when displaced from a large to a small experimental space and vice versa, suggesting that they used the relative metrics of the environment. However, when tested with a transformation (affine transformation) that alters the geometric relations between the target and the shape of the environment, chicks tended to make more errors based on geometric information when tested in the small than in the large space. These findings suggest that the reliance of the use of geometric information on the spatial scale of the environment is not restricted to the human species.     

Comparison of group climate in an eating disorders partial hospital group and a psychiatric partial hospital group

Women in an eating disorders partial hospital program and a psychiatric partial hospital program were compared on a self-report measure of group climate following a psychodynamic-interpersonal therapy group. Those with eating disorders experienced their groups as more engaged and as more avoiding than those in the psychiatric partial hospital group. Therapists may be able to use initial heightened engagement in eating disorder groups to counteract the tendency to avoid content.     

Organizational identification as a trigger for personal well-being: Associations with happiness and stress through job outcomes

Recent literature highlights that well-being, happiness, as well as personal stress, has become important for guiding public policy in areas that might involve suboptimal behaviour. Positive life outcomes can extend from one field of life (family, work, sport, children, hobbies, etc.) to another, multiplying success, performance, and health. In the present study, we aimed to verify whether the positive relation between organizational identification and employees' experiences then extends also into a positive association with more general well-being that is unrelated to the work context. For this purpose, we considered two proxies of organizational well-being: job satisfaction (on the positive side) and turnover intention (on the negative side) as well as the distal associations with happiness. The study involved 305 workers who completed a questionnaire made up of five scales: organization identification, job satisfaction, turnover intention, happiness, and personal stress. We found that organizational identification is positively related to employees' job satisfaction and negatively related to their intention to leave. Afterwards, job satisfaction and turnover intention were related to personal stress and happiness, suggesting a positive effect of organizational identification above and beyond the work context.     

Psychophysiological correlates of organizational change and threat of unemployment among police inspectors

The study examined psychosocial work-conditions and physiological reactions among thirty-six police inspectors (median age 45 years, 81% males) who participated in a reorganization. At this time, subjects were threatened by unemployment and had to reapply for their positions in a new police district. Data were collected during the reorganization and at three years follow-up, by means of questionnaires (Stress Profile) and blood samples. The blood samples were used to determine serum levels of gammaglutamyltransferase (GGT), glucose, lipids, prolactin, testosterone and cortisol. The results show a positive association betweenworry about employment and symptoms ofburnout during the reorganization. Mean scores for the Stress Profile sub-scalesworry about employment (p<.01) andwork-load (p<.05) decreased between measurements but an impairment inrelationships with management was noticed (p<.05). No significant changes were observed in terms of self-rated health complaints. Significant decreases in total cholesterol (p<.0001), LDL-cholesterol (p<.0001), LDL/HDL-ratio (p<.01), prolactin (p<.0001), as well as increases in testosterone (p<.01) and cortisol (p<.001) were observed for the whole sample. Glucose decreased with marginal significance (<.07). Controlling for age and gender, multivariate regression analyses showed that subjects who reported deteriorations insatisfaction with work manifested the most modest decreases in prolactin (p<.05). Also, the decrease in glucose was larger for subjects who experienced impairments in,satisfaction with work (p<.05), information (p<.05), task-oriented leadership, (p<.05), andrespect and dignity (p<.05). Subjects who perceived deteriorations in theethical and moral standards of the organization increased their cortisol level to a lower degree than their counterparts (p<.05). Favorable changes in employment status and psychosocial work environment seem to be related to improved physiological functioning.     

Rigid and non-rigid kinetic depth effect with rotating discrete helices

Summary To examine the conditions in which human observers fail to recover the rigid structure of a three-dimensional object in motion we used simulations of discrete helices with various pitches undergoing either pure rotation in depth (rigid stimuli) or rotation plus stretching (non-rigid stimuli). Subjects had either to rate stimuli on a rigidity scale (Experiments 1 and 2) or to judge the amount of rotation of the helices (Experiments 3 and 4). We found that perceived rigidity depended on the pitch of the helix rather than on objective non-rigidity. Furthermore, we found that helices with a large pitch/radius ratio were perceived as highly non-rigid and that their rotation was underestimated. Experiment 5 showed that the detection of a pair of dots rigidly related (located on. the helix) against a background of randomly moving dots is easier at small phases in which the change of orientation across frames is also small. We suggest that this is because at small phases the grouping of dots in virtual lines does occur and that this may be an important factor in the perceived nonrigidity of the helices.This research was supported by MPI 60% (1987, 1988) and CNR (1986), 1987, 1988) grants to Clara Casco and Sergio Roncato and Grant CNR 90.01603.PS93 to Giorgio Ganis.     

Change in Attachment Dimensions and Reflective Functioning Following Emotionally Focused Group Therapy for Binge Eating Disorder

The current study examines change in attachment variables from pre- to six months post-emotionally focused group therapy (EFGT) for binge eating disorder (BED). A clinical sample of 118 women and men with BED attended 20 sessions of EFGT and completed the Adult Attachment Interview pre- and six months post-treatment. There was a significant increase in secure attachment style classification, significant increases in Coherence of Mind and Reflective Functioning scores, and significant decreases in both unresolved/disorganized attachment style classification and scale scores from pre- to six months post-treatment. Interventions specific to EFGT, common therapeutic factors and group process interventions may have contributed to changes in these attachment variables. The current study demonstrated that EFGT is a promising treatment for facilitating change in attachment in women and men with BED.
