Future orientation of institutionalized and noninstitutionalized delinquents and nondelinquents

The present study is an analysis of the relationship between delinquency, institutionalization and future orientation, based on a social-learning theoretical framework. Two hundred and forty male adolescents (institutionalized and noninstitutionalized delinquents and nondelinquents) answered open and structured questions concerning their anticipations and evaluations of the future. The data were analysed by analyses of variance and t-tests and partly confirm the hypotheses: Delinquents structure their future in a less differentiated, less extended, and more internal way than nondelinquents. This was especially true for the institutionalized delinquents. However, delinquents structured their fears concerning their personal development more extensively than nondelinquents. Future orientation varied according to the length of institutionalization in different domains of life. These results do not support the dominant assumption of the literature that delinquents have an unrealistic future orientation. Rather, it is shown here that institutionalized delinquents anticipate rather negative future events which they expect to occur shortly after the time of their release. However, the present results have to be cautiously interpreted on account of the special selection of the sample and the rather short duration of institutionalization. Also, the method of a differentiated measurement of future orientation used here is hardly practiced in the literature though such a conceptualization as a multidimensional construct seems to be theoretically fruitful.     

Poisson signal-detection theory: Link between threshold models and the Gaussian assumption

The Gaussian model of signal detection cannot fit asymmetric data as long as the variances of the distributions are kept equal. It is therefore common practice to assume unequal variances in order to fit these data. But this assumption leads to the well-known crossover problem. The present paper provides new arguments for the abandonment of the Gaussian model with unequal variances. In its stead, this paper reevaluates multiple-parallel-threshold models. In particular, the Poisson model turns out to be very useful: it can handle data with any degree of asymmetry, giving a reasonable interpretation of the two parameters of the receiver-operating characteristic. The three-state-threshold model (Krantz, 1969) is given a new interpretation in light of the Poisson model. The slope of Poisson double-probability plots turns out to be much closer to unity than is predicted by the Gaussian approximation.     

Prophylactic psychiatry

The great contributions of Gantt to the problems of prophylactic psychiatry are pointed out. The author reviews his experiences with a 30-year follow-up of a population of 1800 persons. Over the 30 years, there appeared to be a 50% increase of neuroses, which raises great problems for mental health services. The Berlevåg population was offered optimal psychiatric services. Behavior therapy of neuroses and drug treatment of depression may possibly have lowered the prevalence of mental disorders. Psychophysiologic tests were used in the project. It is hoped that such tests may be utilized for early detection and treatment of mental disorders.     

Differential effects of person in the dog and in the human

People have marked effects on dog’s heart rate, with great individual variations for different persons. Apparently people to which the dog is attached have the greatest effect upon heart rate. Replications of the animal experiments using the psychotherapist and two other people revealed no effects upon the heart rate of a schizophrenic human. In the human the effects of people are probably best demonstrated in connection with verbal communication.     

JUST WAR THEORIES RECONSIDERED: Problems with Prima Facie Duties and the Need for a Political Ethic

This essay challenges a “meta‐theory” in just war analysis that purports to bridge the divide between just war and pacifism. According to the meta‐theory, just war and pacifism share a common presumption against killing that can be overridden only under conditions stipulated by the just war criteria. Proponents of this meta‐theory purport that their interpretation leads to ecumenical consensus between “just warriors” and pacifists, and makes the just war theory more effective in reducing recourse to war. Engagement with the new meta‐theory reveals, however, that these purported advantages are illusory, made possible only by ignoring fundamental questions about the nature and function of political authority that are crucial to all moral reflection on the problem of war.     

Naturalistic Partial Sleep Deprivation Leads to Greater Next-Day Anxiety: The Moderating Role of Baseline Anxiety and Depression

The detrimental effects of insufficient sleep on emotional functioning have been well established. Total sleep deprivation usually leads to increased anxiety and depressive symptoms the following day. However, no study has yet examined the relationships between unmanipulated partial sleep deprivation and next-day symptoms of anxiety and depression in everyday life, which this study sought to characterize. Participants (N = 94) completed daily diary surveys twice per day for 2 weeks without instructions to alter their sleep in any way. Nights of spontaneous, naturally occurring partial sleep deprivation were followed by increased levels of self-reported symptoms of anxious arousal the next day, but were unrelated to next-day symptoms of anhedonic depression or general distress. The relationship between partial sleep deprivation and next-day anxious arousal was found to be moderated by both baseline depressive symptoms and anxiety such that individuals reporting higher levels of depression or anxiety at baseline showed relatively greater increases in symptoms of anxiety following partial sleep deprivation. These results suggest that partial sleep deprivation occurring in everyday life can lead to higher next-day levels of anxious arousal, a relationship that is particularly deleterious for individuals with higher overall levels of anxiety or depressive symptoms.
