对信息源的正向跟随倾向对决策效果的影响*

采用实验研究的方法,检验了二元选择情形下高准确率信息源(准确率x >50%)和低准确率信息源(准确率为1?x)对决策者预测效果的影响。尽管从逻辑上二者从准确率层面具有完全相等的信息价值,然而研究结果显示,决策者更倾向于采用正向跟随而非逆向跟随的方式处理来自信息源的信息。这导致低准确信息源的价值未能得以充分利用。学习和信息源的规范性对该信息处理倾向起到调节作用。     

Work strain and the post-discharge adjustment of patients following a heart attack

Abstract

The role of work characteristics in determining return to work after an acute coronary event was examined. One hundred and forty nine patients were enrolled. One year post-discharge, 74 had returned to work. Work characteristics (decision latitude, and opportunity for social interaction at work), together with age, depression, and medical prognosis, correctly classified work status in 78% of cases. At 12 months post-discharge, patients who had not returned to work recorded significantly poorer levels of adjustment compared to those who had returned to work. A better quality of life is associated with a lower level of depression pre-hospitalization, ownership of a larger home, being male, and having a more positive work environment. The findings suggest that the pre-illness work environment of the patient is a factor influencing return to work, which needs to be considered in rehabilitation programmes.     

Lifestyle effects of group health education for patients with coronary heart disease

Abstract

In the present study, effects of a health education (INFO) and a PsychoEducational Prevention (INFO + PEP) Programme were Investigated in three hospitals. These programmes were offered to groups of coronary heart disease (CHD) patients and their partners alter discharge from hospital. The INFO was offered to 127 CHD patients in addition to FIT (i.e. standard medical care and physical training). The PEP was offered to 90 Patients in, addition to the INFO and FIT. A control group of 122 patients received only FIT. The INFO and the PEP consisted of four weekly two-hour group sessions each. In addition, the PEP was followed by seven telephone follow-up contacts.

On average, patients improved their lifestyles during the first three months. Between three and twelve months an extra improvement was found for eating habits, whereas there was a relapse for smoking and a sedentary lifestyle. In the short term, angina pectoris and a longer period of heart complaints were parallelled with a decrease in the risk of maintaining unhealthy eating habits, whereas in the long term a longer period of heart complaints a younger age and unemployment predicted a lower risk of maintaining unhealthy eating habits In the short term living with a partner and in the long term female gender were predictive of continued smoking behaviour In the short term, older age, a first CABG and a specific hospital setting decreased the risk of a continued sedentary lifestyle.

The FIT + INFO + PEP had a favourable short-term effect on eating habits. For smoking and a sedentary lifestyle, however, there were negative effects. In the short term patients in the FIT +INFO and those in the FIT +INFO+PEP had significantly more problems in quitting a sedentary lifestyle than those in the FIT intervention in the long term, patients in the FIT + INFO had significantly more problems in stopping smoking compared to these in the FIT.     

Effect of cooling rate on size-dependent atomic ordering of CoPt nanoparticles

We report on the effect of cooling rate on the size-dependent atomic ordering of CoPt nanoparticles using aberration corrected high-resolution transmission electron microscopy. It was found that cooling rate plays a crucial role in promoting atomic ordering during the cooling process after annealing. Nanoparticles of ≈3?nm in diameter show the A1-disordered phase after annealing at 873?K for 1?h followed by rapid cooling (110?K/min), while the L1₀-ordered phase is obtained when the cooling rate is slow (1.5?K/min). The disordered phase is also obtained by rapid cooling after annealing at 973?K for 1?h. These results unambiguously indicate that the order–disorder transformation temperature is reduced to a temperature at least lower than 873?K for CoPt nanoparticles smaller than 3?nm in diameter. The slow cooling process promotes the atomic ordering, which resulted in an enhancement of magnetic coercivity as high as 2200?Oe. This study demonstrates that hard magnetic properties of the CoPt nanoparticles can be improved by controlling the cooling rate after heat treatments.     

Rethinking ‘Don't Blame the Victim’

SUMMARY

The psychology of victims and the dynamics of victimhood have been largely ignored by scholars and clinicians. While in past years the tendency has been to blame victims, more recently the tide has turned. It is now politically incorrect to explore the role of victims in violent systems, as exploring the psychology of victims has become synonymous with blaming the victim. While shying away from blame, this article will explore the familial and cultural origins of victimhood, victims' characteristics, their relationships with the perpetrators, and it will offer a victim typology. As we move from btame to a more complex understanding of violent systems, the perpetuation of these systems in our culture, and the role victims play in these systems, we provide ourselves with better tools to predict and prevent further victimization.     

Diagnosing depression in patients with physical diseases using the beck depression inventory (BDI)

Abstract

Four-hundred-and-forty-three patients with a physical illness (355 with coronary heart disease and 88 with chronic pain), 150 unemployed persons and 623 subjects from the normal population in Jämtland, Sweden were tested using the BDI (Beck Depression Inventory). The aim of the study was to investigate whether scores on both the physical and non-physical components of the BDI differed between the patients and the other groups, or whether only the physical component was significantly higher in the patient group, and in such a case whether this could be interpreted as symptomatic of physical disease and not of depression. A cutoff score of ≥ 10 to determine mild depression and two different alternative physical and non-physical components were used. Forty-three percent of the patients with coronary heart disease and 50% of patients with chronic pain were categorized as being at least mildly depressed. Factor analyses indicated that a physical component comprising five items was the most meaningful and could best discriminate the physical symptoms. The patients' scores were significantly higher than those of the other two groups on the physical component but only higher than the normal population sample on the nun-physical component. This supports the idea that the items for physical symptoms in the BDI might be confounding when determining depression in patients with physical diseases. The non-physical component seems to be the best indicator of depression and is recommended as a complement to the total BDI scale when determining the degree of depression in patients suffering from a physical disease.     

Characteristics of Male Batterers in Treatment

Abstract

This article presents information on the characteristics of a clinical population of male perpetrators of intimate partner violence (IPV) court-ordered for batterers' treatment, and how these characteristics co-varied with treatment attrition. The average demographic profile of male batterers in a midwestern treatment program that met present-day treatment guidelines was similar to that found in other studies. In addition, relationship length and status, alcohol/drug use, self-reports of past treatment and mental health issues, and self-report of witnessing or experiencing violence within the home during childhood was also similar. Batterers' self-reports of their own violent behavior were found to vary by data collection technique, with face-to-face interviews eliciting greater admission of violent behavior than paper-and-pencil questionnaires. However, the only predictors of successful treatment outcome were living arrangement at the time of treatment and racial category. Implications of these findings are discussed, and “local effects” program evaluation approaches are suggested.     

Compassionate reappraisal and emotion suppression as alternatives to offense-focused rumination: Implications for forgiveness and psychophysiological well-being

This within subjects experiment (28 females, 26 males) examined three responses to a past interpersonal offender. We contrasted offense-focused rumination with two subsequent, counterbalanced coping strategies: compassionate reappraisal and emotion suppression. Compassionate reappraisal emphasized the offender's human qualities and need for positive change. Emotion suppression inhibited the experience and expression of negative offense-related emotions. Offense rumination was associated with negative emotion, faster heartbeats (i.e., shortened electrocardiogram R-R intervals), and lower heart rate variability (HRV; i.e., the high-frequency component of the R-R power spectrum). By contrast, both compassionate reappraisal and emotion suppression decreased negative emotion in ratings and linguistic analyses, calmed eye muscle tension (orbicularis oculi EMG, electromyography), and maintained HRV at baseline levels. Suppression inhibited negative emotion expression at the brow (corrugator EMG) and slowed cardiac R-R intervals, but without forgiveness effects. Only compassionate reappraisal significantly increased positive emotions, smiling (zygomatic EMG), and social language along with forgiveness.     

Compassion-focused reappraisal,benefit-focused reappraisal,and rumination after an interpersonal offense: Emotion-regulation implications for subjective emotion,linguistic responses,and physiology

This repeated measures psychophysiology experiment studied three responses to a past interpersonal offense (38 females and 33 males). We compared rumination with two offense reappraisal strategies. Compassion-focused reappraisal emphasized the offender's humanity, and interpreted the transgression as evidence of the offender's need for positive transformation. Benefit-focused reappraisal emphasized insights gained or strengths shown in facing the offense. Supporting the manipulations, compassion-focused reappraisal stimulated the most empathy and forgiveness, whereas benefit-focused reappraisal prompted the most benefit language and gratitude. Both reappraisals decreased aroused, negative emotion, and related facial muscle tension at the brow (corrugator). Both reappraisals increased happiness and positive emotion in ratings and linguistic analyses. Compassion stimulated the greatest social language, calmed tension under the eye (orbicularis oculi), and slowed heart beats (R–R intervals). A focus on benefits prompted the greatest joy, stimulated smiling (zygomatic) activity, and buffered the parasympathetic nervous system against rumination's adverse effects on heart rate variability (HRV).
