This article summarizes main results of studies on forensic psychiatric court reports on 166 men who had been persecuted between 1963 and 1991 for a sexual offence leading to the death of the victim. Comparing perpetrators with a single victim and those with multiple victims we found similar results as in two previous studies with smaller samples: Multiple sexual homicide perpetrators showed more often sexual sadism and other paraphilias, as well as antisocial, schizoid and sadistic personality disorders. Follow-up data from the federal criminal records could be obtained for 139 offenders. Ninety perpetrators had been released after a mean detention of 12.2 years, whereas the 49 offenders who were still in prison or forensic psychiatric hospitals had been detained for a mean period of 20.6 years. The non-released offenders showed more often paraphilias as well as antisocial and sadistic personality disorders than the released perpetrators. Paraphilias and antisocial personality traits are empirically well proven risk factors for criminal recidivism with sexual reoffences. In addition, the non-released sexual homicide perpetrators had higher scores in all applied risk assessment instruments (PCL-R, HCR-20, SVR-20, Static-99). Among the released offenders only 1.1% (n=1) reoffended with a completed homicide and 2.2% (n=2) with attempted homicide. The recidivism rates with sexual and other violent reoffences in this sample of sexual homicide perpetrators were similar to those in a large meta-analysis on recidivism in sexual offenders by Hanson and Morton-Bourgon (4). Since well established risk factors had apparently been “used-up” for the decisions about release or non-release, in the follow-up data about the released offenders only age at the sexual homicide and age at the time of release were found as risk factors for recidivism with any violent (sexual or non-sexual) reoffence, i.e. the younger the offender at the time of the homicide and the younger at the time of release, the more likely is the risk of violent reoffending.  相似文献

ObjectivesThe objectives of this research were a) to explore the applicability of ‘motivational climate’ research to early career athletes under the age of twelve, b) to re-examine the concept of ‘motivational climate’ in the light of recent scientific developments, and c) to concurrently study the influences of coaches, parents and peers on athletic motivation.Design and MethodUsing a qualitative design, 40 participants (7–11 years of age) from various sports were interviewed in focus groups, using a semi-structured format to investigate the roles played by coaches, parents, and peers in influencing athlete motivation. An inductive content analysis was conducted to determine which behaviours among these social agents influenced key motivational outcomes.FindingsThe analysis indicated that young athletes experience a motivational climate which shows consistencies with existing models of motivation; suggesting this population is worthy of further study. The influences of coaches related most strongly to the manner in which they perform their roles of instruction and assessment, whereas parents' influences were most salient in terms of the way they support the child's participation and learning. Both parents and coaches exerted influences through their leadership styles, affective responses and pre-performance behaviours. Peers influenced participants' motivation through competitive behaviours, collaborative behaviours, evaluative communications and through their social relationships.ConclusionsThis study provides an insight into the motivational climate experienced by young athletes and helps to delineate the different roles of social agents in influencing their motivation at this early stage of development.  相似文献

Ecology's reputation as a holistic science is partly due to widespread misconceptions of its nature as well as shortcomings in its methodology. This article argues that the pursuit of empirical laws of ecology can foster the emergence of a more unified and predictive science based on complementary modes of explanation. Numerical analyses of population dynamics have a distinguished pedigree, spatial analyses generate predictive laws of macroecology, and physical analyses are typically pursued by the ecosystem paradigm. The most characteristically ecological laws, however, are found in biotic analyses in the functional trait paradigm. Holistic credentials for ecology may thus be restored on two bases: its accommodating complementary modes of analysis and explanation, and its having some laws within the least reductionistic mode consistent with its subject matter. These claims, grounded in the aspectual theory of Herman Dooyeweerd, lead to some suggestions for enhancing the versatility and usefulness of ecology—and other sciences—by balancing different research paradigms under a holistic vision.  相似文献

Social groups of gorillas were observed in three captive facilities and one African field site. Cases of potential gesture use, totalling 9,540, were filtered by strict criteria for intentionality, giving a corpus of 5,250 instances of intentional gesture use. This indicated a repertoire of 102 gesture types. Most repertoire differences between individuals and sites were explicable as a consequence of environmental affordances and sampling effects: overall gesture frequency was a good predictor of universality of occurrence. Only one gesture was idiosyncratic to a single individual, and was given only to humans. Indications of cultural learning were few, though not absent. Six gestures appeared to be traditions within single social groups, but overall concordance in repertoires was almost as high between as within social groups. No support was found for the ontogenetic ritualization hypothesis as the chief means of acquisition of gestures. Many gestures whose form ruled out such an origin, i.e. gestures derived from species-typical displays, were used as intentionally and almost as flexibly as gestures whose form was consistent with learning by ritualization. When using both classes of gesture, gorillas paid specific attention to the attentional state of their audience. Thus, it would be unwarranted to divide ape gestural repertoires into ‘innate, species-typical, inflexible reactions’ and ‘individually learned, intentional, flexible communication’. We conclude that gorilla gestural communication is based on a species-typical repertoire, like those of most other mammalian species but very much larger. Gorilla gestures are not, however, inflexible signals but are employed for intentional communication to specific individuals.  相似文献

We studied 9,220 children referred to a comprehensive mental health crisis stabilization program to examine the impact of caregiver capacity on crisis worker decisions to refer children for intensive community-based treatment as opposed to inpatient psychiatric hospitalization. Due to the different role of caregivers in the child welfare system, analyses were stratified by state custody status. Among both groups, there was a significant inverse association between child mental health need and referral to intensive community-based treatment. For children not in state custody with low mental health need, there was no difference in the likelihood of referral to intensive community-based treatment across levels of caregiver capacity. However, for children not in state custody with medium and high mental health needs, those whose caregivers were deficient or severely deficient were significantly more likely to be referred for intensive community-based treatment than were those who had capable caregivers. Multivariate analyses demonstrated similar results after controlling for potential confounding variables and confirmed that caregiver capacity contributes significantly to the logistic model’s classification accuracy. Results suggest further investigation of the impact of caregiver capacity on mental health crisis worker referral decisions is needed.  相似文献

The purpose of this investigation was to examine longitudinally gestational age and developmental differences in preterm infants' self-regulatory abilities in response to a painful stressor, as well as associations between behavioral and cardiovascular responses. Participants included 49 healthy premature infants. Behavioral and cardiovascular responses to a heel stick blood draw were compared between infants of 28-31 and 32-34 weeks' gestation age at birth. Both gestational age groups displayed behavioral and cardiovascular indications of stress in response to the blood draw. However, both shortly after birth and several weeks later, infants born at younger gestational ages (28-31 weeks) were more physiologically reactive. Evidence that the behavioral stress responses of 28-31 weeks' gestation age group preterm infants do not reflect their physiological responses suggests that evaluation of preterm infants' experiences and risk require assessments of both physiology and behavior. The greater stress vulnerability of the 28-31 weeks' gestation group relative to the 32-34 weeks' gestation group and the implications of this for subsequent development are discussed.  相似文献

Chronic illnesses are associated with multiple stressors that compromise quality of life (QOL). Implicit in many of these is the concept of illness intrusiveness, the disruption of lifestyles and activities attributable to constraints imposed by chronic disease and its treatment. This study tested the illness intrusiveness theoretical framework in epilepsy and compared the impact of pharmacological and surgical treatments on illness intrusiveness and QOL. Cross-sectional data compared three epilepsy groups (N = 145): (a) 40 patients admitted for presurgical evaluation to an Epilepsy Monitoring Unit; (b) 52 patients treated pharmacologically; and (c) 53 post-surgical patients. Illness intrusiveness differed significantly across epilepsy patients with the differences primarily related to seizure control. Illness intrusiveness varied inversely with seizure control (p < .05). Seizure freedom, whether achieved by surgical or pharmacological treatments, was associated with maximal reduction of illness intrusiveness. Increased illness intrusiveness correlated significantly with decreased QOL and increased depressive symptoms. Perceived control over diverse life domains correlated positively with QOL and psychosocial outcomes. Path analysis supported the validity of the illness intrusiveness theoretical framework in epilepsy. Illness intrusiveness is an important determinant of the psychosocial impact of epilepsy and its treatment. Effective pharmacological or surgical treatment may reduce illness intrusiveness in epilepsy. Findings also offer encouragement that QOL in epilepsy, as in other chronic conditions, may be enhanced by multidisciplinary bio-psychosocial efforts. Health care providers should consider multifaceted interventions to reduce illness intrusiveness and, thereby, improve QOL.  相似文献

Over the course of the first year of life, infants develop from being generalized listeners, capable of discriminating both native and non-native speech contrasts, into specialized listeners whose discrimination patterns closely reflect the phonetic system of the native language(s). Recent work by Maye, Werker and Gerken (2002) has proposed a statistical account for this phenomenon, showing that infants may lose the ability to discriminate some foreign language contrasts on the basis of their sensitivity to the statistical distribution of sounds in the input language. In this paper we examine the process of enhancement in infant speech perception, whereby initially difficult phonetic contrasts become better discriminated when they define two categories that serve a functional role in the native language. In particular, we demonstrate that exposure to a bimodal statistical distribution in 8-month-old infants' phonetic input can lead to increased discrimination of difficult contrasts. In addition, this exposure also facilitates discrimination of an unfamiliar contrast sharing the same phonetic feature as the contrast presented during familiarization, suggesting that infants extract acoustic/phonetic information that is invariant across an abstract featural representation.  相似文献
