Institutional caregiving can have adverse effects on children, yet little is known about the caregivers of institutionalized young children. We surveyed staff in three Ukrainian Baby Homes about their attitudes toward the nature of their work and the needs of the young children in their care. Seventy‐one caregivers completed anonymous, semistructured surveys. Popular reasons for working in Baby Homes included benefits and convenient work shifts, morality, and affection for children. Caregivers reported both favorable aspects of the work (enjoyment of children, professional satisfaction) and work difficulties (conflicts, lack of cooperation, little administrative support). In addition, they noted deficiencies in care: high caregiver–child ratio, frequent care disruptions, and lack of stimulation. Direct caregivers (in‐room “nannies,” educators, and nurses) and other providers (e.g., clinic nurses, physicians, therapists) differed in university‐degree attainment, professional motivation, enjoyment of children, professional satisfaction, and perceptions of self as substitute mother. A number of potential “windows for change” were identified, including recognition of deficiencies in institutional care and possibilities for improvement. Implications for interventions are discussed, including the need to consider lack of staff support, high emotional stress, internal conflicts, beliefs and attitudes about institutionalized children and their biological parents, and differences in staff educational achievement. 相似文献

The present study tested the role of right-wing authoritarianism (RWA), terrorist threat, and sociopolitical 'climate' as predictors of support for governmental anti-terrorism policies and actions. Two dimensions of analysis were defined: the presence versus absence of al-Qaeda attacks, and adherence to surveillance versus anti-surveillance mainstream politics. In order to study the influence of these two contextual dimensions on the expression of attitudes, we selected four European countries that fall into these two dimensions--Poland, Belgium, Spain, and the UK. Results from our study provide support for the contention that attitudes towards restrictions of civil rights are related to RWA independently of the cultural context. Moreover, in the UK sample, we found that the threat of terrorism increases acceptance of limitations of civil liberties, but only among people who hold authoritarian beliefs. However, in Spain, the other country that experienced terrorist attacks, this moderation effect was not found which is interpreted in terms of differences in the sociopolitical climate in both countries. As predicted, we did not find such moderation effect in countries in which threat is relatively low (Poland and Belgium). The results are discussed with reference to the conceptual framework based on the importance of fear experiences, security-focused policies, as well as the specific cultural context in the study of reaction to terrorist threat. 相似文献

Effort discounting refers to the decrease in the subjective value of a reward as the effort required to obtain the reward increases. The main aims of this study were to ascertain whether the amount of the reward affects the steepness of the effort discounting process for hypothetical monetary rewards, to identify whether this steepness depends on the type of effort that is required, and to determine whether the steepness of different types of effort covary at the individual level. Two types of effort were studied under hypothetical choice situations: physical effort and cognitive effort. Both physical and cognitive effort discounting were well described by the hyperbolic model. Large rewards were discounted less steeply than small rewards for both types of effort. This finding agrees with the results of prior studies which have found that larger rewards have greater motivational power. In addition, the steepness of physical effort discounting was positively correlated with the steepness of cognitive effort discounting, which suggests that the effort discounting process is a trait‐like characteristic within an individual. 相似文献

The present study examines the congruence of individuals' minimum preferred amounts of voice with the prospect theory value function across nine countries. Accounting for previously ignored minimum preferred amounts of voice and actual voice amounts integral to testing the steepness of gain and loss functions explicated in prospect theory, we use curve fitting to show that ratings of procedural justice fit prospect theory's value function specifically. Further, we investigate the form of this function across nine countries that range in power distance. Results suggest that the form of the value function is congruent with prospect theory, showing an S‐shaped curve that is steeper in the loss than in the gain domain. Further, this pattern is similar across countries. Theoretical and practical implications of these results for both decision making and organizational justice are discussed.

Theories of ethical leadership provide important insights about the effect of leader’s ethics on the relationship between leaders and followers. However, there is an increasing demand for addressing key constructs that enhance the capacity to explain theoretical aspects of ethical leadership. The purpose of this study is to expand the theoretical framework of ethical leadership based on Korean traditional leadership by focusing on personal cultivation, morality, and social responsibility. Using a framework of intrapersonal process as leadership and core value and competence as components of leadership, this study examines the ethical aspects of Korean traditional leadership and provides the implications to further develop the theory of ethical leadership. It is found that ethical integrity ensued from sugi (self-cultivation) is an essential precondition to develop leadership, and the core value of ethical leadership includes Zhixin-Chijing (cultivation of the mind and internal piety) and the competence consists of both Ipzhi (setting a solid self-vision/establishing goal) and Silsim (practical mind, grasp changes in reality with a sound mind) in Korean traditional leadership that contributes to expanding the theoretical understanding of ethical leadership. Implications for future research in the area of ethical leadership are discussed. 相似文献

Recent research suggests that the content of iconic memory (IM) and fragile visual short-term memory could be associated with a similar level of conscious accessibility as working memory (WM). The results of our studies, in which we used a subjective visibility scale in a partial-report change detection paradigm, indicate that it is possible to distinguish separate stages of memory based on both discriminative accuracy and conscious accessibility. The highest scores were associated with IM and the lowest with WM, while somewhere in the middle there was fragile memory. Based on classical assumptions, WM accessibility should be greater than the other two types of memory; however, our study showed that this might not always be the case. We discuss the potential sources of this outcome, of which one may be the task construction, as we only tested items that were directly in the focus of attention. 相似文献

We use the results of a large online experiment on word knowledge in Dutch to investigate variables influencing vocabulary size in a large population and to examine the effect of word prevalence—the percentage of a population knowing a word—as a measure of word occurrence. Nearly 300,000 participants were presented with about 70 word stimuli (selected from a list of 53,000 words) in an adapted lexical decision task. We identify age, education, and multilingualism as the most important factors influencing vocabulary size. The results suggest that the accumulation of vocabulary throughout life and in multiple languages mirrors the logarithmic growth of number of types with number of tokens observed in text corpora (Herdan's law). Moreover, the vocabulary that multilinguals acquire in related languages seems to increase their first language (L1) vocabulary size and outweighs the loss caused by decreased exposure to L1. In addition, we show that corpus word frequency and prevalence are complementary measures of word occurrence covering a broad range of language experiences. Prevalence is shown to be the strongest independent predictor of word processing times in the Dutch Lexicon Project, making it an important variable for psycholinguistic research. 相似文献

The present study was designed to examine whether age, gender, and depression level may moderate the effect of exposure to suicide news on the suicidality of college students in Taiwan. A representative sample of 3,222 college students were recruited from Southern Taiwan with a total of 2,602 useable surveys returned. Results showed that only depression level reached a significant moderating effect and further examination showed that the exposure to suicide news significantly predicted suicidality solely in the severely depressed group. 相似文献
