The psychometric properties of the Icelandic version of the World Health Organization five wellbeing index (WHO‐5) were evaluated using two samples, a randomly selected sample (N = 3,896) from the Icelandic National Registry and a convenience sample of primary care patients (N = 126). The factor structure of the scale was tested with confirmatory factor analysis (CFA). The correlation between the WHO‐5 and other measures of depression and anxiety were calculated to assess the scale's convergent and divergent validity. The discriminant validity of the WHO‐5 was explored with a receiver operating analysis compared to the Mini International Neuropsychiatric Interview. The CFA indicated that the factor structure of the WHO‐5 was one‐dimensional and factorial invariant between groups. The internal reliability of the WHO‐5 was adequate and the convergent, divergent and discriminant validity of the WHO‐5 was supported. It is concluded that the psychometric properties of the Icelandic version of the WHO‐5 are satisfactory.  相似文献

Decision makers intending to avoid risk in a decision situation can choose a less risky alternative (passive risk avoidance) or intervene actively in an alternative applying a risk‐defusing action (active risk avoidance). In Experiment 1 (64 participants), we compared active and passive risk defusing in two framing conditions. In the negative frame, in the uncertain alternative, a change to the worse was possible; in the positive frame, a change to an improvement was possible. Each participant decided in both framing conditions. As expected, active risk avoidance behavior for preventing a negative outcome (i.e., in the negative frame) was more likely than for promoting a positive one (i.e., in the positive frame). If decision makers did not or could not actively defuse the risk, they chose in correspondence to the classical pattern: risk avoidance in the positive frame and risk seeking in the negative one. We replicated the latter result in a second experiment (32 participants). The classical framing pattern in passive risk avoidance in both experiments is remarkable, because participants were not presented or did not search for exact probabilities.

In this study, we use quantitative and qualitative data to analyze how historical events shaped skilled emigration and integration of two Eastern European groups into the USA. Some of these migrants lost all interest in their country of origin and seek to fully assimilate to the new society. Others developed a new type of identity, as global citizens rather than of a particular country. They are willing to learn and understand the new society, but at the same time, they keep in touch with the home country. These two fundamental avenues of skilled migrant integration are related to individual characteristics as well as structural forces, and may highlight potential subsequent moves, addressing the global circulation of skilled international migrants.  相似文献

While anti-Semitism had been manifested in Europe since the Middle Ages, the emergence of the Nazi regime raised that phenomenon to a new level. Some publications supported by Nazi Germany tried to effect public opinion in Turkey regarding “scientific” anti-Semitism. The authors of this study support the view that this ideology has not been able to achieve broad support from the Turkish nation or its government. Nevertheless, anti-Semitism did reach Turkey through foreign publications. The specific anti-Semitic events that occurred in the Thrace Region of Turkey in 1934 and the anti-Semitic Milli ?nk?lap (National Revolution), which had a pivotal role in those events, were inspired by Nazi Germany. Nevertheless, Germany does not seem to have played an active role during the events. This article will examine the issues of the openly anti-Semitic Milli ?nk?lap, published from 1 May 1934 to 1 July 1934 and try to compare the influence of Julius Streicher's infamous Der Stürmer on the ideology and content of Milli ?nk?lap.  相似文献

Altered states of consciousness (ASC), especially hallucinatory ones, are philosophically and scientifically interesting modes of operation of the mind–brain complex. However, classical definitions of ASC seem to capture only a few common characteristics of traditionally regarded phenomena, thus lacking exact classification criteria for assessing altered and baseline states. The current situation leads to a priority problem between phenomena-based definitions and definition-based phenomena selection. In order to solve the problem, this paper introduces a self-mapping procedure that is based on a three-part analysis on certain aspects of hallucinatory altered consciousness. Starting with commonalities found in current definitions of ASC, issues with self-evaluation, sources of data, and baseline comparison are analyzed first. Next, the concept of alterations is examined with respect to temporal dynamics, change mechanisms, and mental subsystems. Finally, hallucinatory phenomena are discussed regarding various definitions, the relationship between “external” and “internal,” and the “trueness” issue of hallucinations. Conclusive to the analysis above, a technically based working definition of ASC and a stepwise operationalization procedure are also proposed.  相似文献

The ability of animals to delay gratification is crucial for complex goal-directed action. It may help them in making effective decisions when facing a choice. We tested the ability of nine long-tailed macaques (Macaca fascicularis) to delay gratification in several experiments. In exchange tasks, subjects had to keep a small piece of cookie before returning it to an experimenter in order to get a larger food amount. Results showed that animals could wait between 10 s and 10 min depending on individual and sizes of reward. In another experiment, subjects could immediately give back the initial piece of cookie then wait for the return. Their performances more than doubled, demonstrating the role of consumption inhibition in postponing gratification. Such achievements underscore delays of gratification which until now were not thought possible in monkeys. Finally, subjects were presented with an accumulation of food pieces added at short intervals until they seized them. They mostly waited between 30 s and 1 min, which points at the consistency of our data, compared to those of other studies. Our results indicate that long-tailed macaques anticipated the duration of delays. We may account for their remarkable performances by their achievements in the social context.  相似文献

Our aim was to investigate the functional underpinnings of autobiographical memory (AM) impairment in multiple sclerosis (MS) patients. To that end, 18 patients and 18 controls underwent the autobiographical interview (AI). Subsequently, the 36 participants underwent a functional magnetic resonance imaging (fMRI) session designed to assess the construction and elaboration of AMs. A categorical control task was also presented. Patients were trained in the fMRI procedure to optimise the procedural aspects accompanying the task itself. Although the patients obtained significantly poorer AI scores (p < .001), their performance on the easier AM fMRI task was efficiently carried out, allowing relevant comparisons with healthy controls. Relatively to healthy controls, the patients showed increased and bilateral cerebral activations (p < .005) during the construction and elaboration phases. The prefrontal, temporal and posterior cerebral region activations were located within the core network sustaining AM, with the bilateral prefrontal region being centrally involved. The parametric neural responses to the difficulty of access and amount of details of memories were also significantly different for the two groups, with the right hippocampal region showing a particularly increased recruitment (p < .005). The findings suggested the presence of functional cerebral changes during AM performance and supported the presence of AM retrieval deficit in MS patients.  相似文献

It has been assumed that overweight individuals show weak inhibitory control capacity leading to a failure to resist external cues for palatable food and that this deficit underlies the recently reported empirical association between obesity and attention deficit/hyperactivity disorder (ADHD). In childhood and adolescence, empirical research on this issue is scarce. Here, the hypothesis is tested that high body weight is associated with weak inhibitory control performance and that this association is moderated by age.

The sample included 177 overweight and obese children and adolescents (BMI: M = 29.2, SD = 4.33; BMI-SDS: M = 2.45, SD = 0.43) between 8 and 15 years. Inhibitory control was assessed by a Go/No-Go task and an Interference Task. A principal component analysis yielded two components: impulsivity (fast but invalid responses) and inattention (highly variable reaction times).

While controlling for age, gender, and maternal education level, we found that more obese children/adolescents showed more inattention. As indicated by a significant interaction effect, exclusively at younger ages, high impulsivity was associated with high body weight.

The results thus confirm a link between low inhibitory control capacity and high body weight and might point to a developmental period with heightened significance of impulsivity for weight gain.  相似文献

The purpose of the present study was to examine the effects of 12-week exercise interventions on physical self-perceptions of male university students. The study also aimed to investigate the relationships between the changes in physical self-perceptions and the changes in some physiological measures after 12-week exercise programs. Forty-eight male university students aged from 19 to 25 years were enrolled in this study. Participants were randomly and equally assigned to swimming, running, cycling and control conditions. The Physical Self-Perception Profile was administered to all participants before and after 12-week exercise programs. Additionally, strength, maximal oxygen uptake (VO(2max)) and body compositions were assessed before and after interventions. Participants in the exercise groups attended swimming, running or cycling sessions for 40 min per day, 3 days per week with 60-70% of their heart rate reserves, while those in the control group did not attend any regular physical activity. The results of 4 × 2 × 5 MANOVA with the dimensions of physical self-perceptions as within-subject factor revealed that all groups including the control group revealed better physical-self-perceptions from pre- to post-test. Results of 4 × 2 × 3 MANOVA with physiological measures as within-subject factor revealed that VO(2max) values of participants in the swimming group improved more than the other groups. On the other hand, no significant differences were observed in strength scores and body fat levels among groups. Furthermore, no significant associations were obtained between the changes in physical self-perception dimensions and the physiological measures.  相似文献
