The development of hierarchical factor solutions

Although simple structure has proved to be a valuable principle for rotation of axes in factor analysis, an oblique factor solution often tends to confound the resulting interpretation. A model is presented here which transforms the oblique factor solution so as to preserve simple structure and, in addition, to provide orthogonal reference axes. Furthermore, this model makes explicit the hierarchical ordering of factors above the first-order domain.Grateful acknowledgment is given to Dr. Lloyd G.

Sensitization and aversive conditioning: Effects on the startle reflex and electrodermal responding

Animal data suggest that shock sensitization as well as aversive learning potentiates the acoustic startle reflex. The present experiment tested, whether this shock sensitization also occurs in human subjects and whether it precedes aversive conditioning. Sixty subjects viewed—prior to conditioning—a series of slides of different emotional contents including the to be conditioned stimuli (CSs). Afterwards, the experimenter attached the shock electrodes and initiated shock exposure. Then, subjects were randomly assigned to view a series of two slides, each for eight acquisition trials in which one slide was followed by a shock. Subsequently, extinction trials (12 for each slide) were administered. During preconditioning, acquisition, and extinction, startle probes occurred unpredictably during and between slide viewing. Preconditioning data replicated previous results by Lang and his associates, showing that the startle response magnitude is directly related to the affective valence induced by the slides. Shock exposure strongly facilitated the startle reflex magnitude. This shock sensitization was absent for the skin conductance response. Course of learning also varied for both response systems. The data suggest that startle reflex potentiation indexes the acquisition of an avoidance disposition, which is preceded by a general sensitization of the protective reflexes. Skin conductance learning follows arousal changes and is modulated by cognitive processes.

Iraq and Afghanistan Veterans’ Experiences Living with their Parents after Separation from the Military

When military service members separate from the military, many return to their families of origin, living with their parents for a period of several weeks to years. While research with veterans and their spouses has documented the particular strain of this reintegration period on veterans and their partners, little research to date has examined veterans’ experiences living with their parents. The present study sought to fill this research gap by investigating veterans’ experiences living with their parents using qualitative, in-depth interviews with Iraq and Afghanistan veterans in California. Overall, veterans appreciated the instrumental and emotional support their parents provided when they separated. However, in some cases, living with parents also produced conflict and strain. In situations where adult veteran children had difficulty with the transition to civilian life or returned with mental health problems, parents were often the first to identify these problems and to support their children in accessing appropriate care. We analyze these findings in light of family systems theory, identifying ways in which adult veteran children continue a process of differentiation while living with their parents and maintaining emotional connectedness. We suggest ways that clinicians can better support veterans and their parents through the reintegration period and recommend that programming for military families explicitly include parents of service members in addition to conjugal families.     

Social support from fellow group members triggers additional effort in groups

This research demonstrates social support from fellow group members as unique trigger of additional effort and performance in groups. Support‐induced effort gains are shown both compared with groups without social support and individual work. Study 1 examined existing beliefs about motivating group work among employees with professional group work experience (n = 130). The results revealed social support as one of the most frequently reported sources of group‐induced effort gains. Study 2 explored self‐reported effort intentions in group training scenarios among athletes (n = 94). Finally, Study 3 examined performance as a manifest indicator of effort in an experimental persistence task among students (n = 88). The results of Study 2 and Study 3 showed significant gains due to social support in both self‐reported effort and manifest performance, respectively. Together, the results demonstrate that receiving social support from fellow group members leads to higher effort in groups at the level of existing beliefs about motivating group work, at the level of effort intentions, and at the level of manifest performance behavior. The observed findings cannot be explained by established sources of motivation gains in groups such as social comparison or social indispensability. Copyright © 2014 John Wiley & Sons, Ltd.     

Facing an incompetent leader: The effects of a nonexpert leader on subordinates' perception and behaviour

We investigated the effects of a leader's task-incompetence on how subordinates perceive and interact with their leader. In Study 1, 80 participants in a subordinate role interacted via e-mail and in Study 2, 80 participants interacted face-to-face with either a competent or an incompetent leader on a problem-solving task. Participants' dominance behaviour, how much they resisted the leader's influence, their perception of the leader, and their task involvement were assessed. As predicted, subordinates perceived the leader's incompetence as a lack of power and compensated for it by taking on a more powerful position themselves (i.e., more dominance behaviour, more resistance to the leader's influencing attempts). In sum, having a task-incompetent leader affects not only the subordinates' perception of the leader but also how the subordinate interacts with the leader.     

BONE MARROW TRANSPLANTATION IN A PATIENT WHO EXPERIENCED TORTURE IN A PRISONER OF WAR CAMP: NARCISSISM AND SURVIVAL

Post-traumatic stress disorder has been described as a syndrome from which an individual may suffer as a result of extraordinary trauma. Torture of prisoners of war in Serbian camps during the war in Croatia is just such a stressful situation that requires mobilization of all defense mechanisms of an individual. The authors present a case study of a former prisoner of war who acquired acute myelogenous leukemia several months after release and was treated with bone marrow transplantation. On release the patient was medically examined, like all prisoners of war, and the findings did not suggest any disease. Because of the situation, the patient was in psychotherapeutic observation and treatment after his illness was diagnosed and throughout the transplantation treatment.     

Global problems,globalization, and predictability

The term globalization is questioned in its validity and applicability to structures other than verbal. Globalization is a historical term which changes its meaning with time and culture. It is not only that its content changes but the validity of a globalization concept changes with the historical perspective. Morever, solution of global problems depends heavily on the correct analysis of the problem. Without such an analysis there is no possibility to find even an approximate solution. Hence, predictability is impossible. There is no trend which is sufficiently long to make any reliable prediction for global problems other than the most simple ones.
