In case of special engineering projects of important relevance it is interesting to pay attention to several possible risks; some of them are in the field of morality or ethics. Due to the social importance of these risks, additional considerations or even additional warranties are justified.  相似文献

High-quality arguments have strong and lasting persuasive effects, suggesting that people can distinguish high- from low-quality arguments. However, we know little of what norms people employ to make that distinction. Some studies have shown that, in evaluating arguments from consequences, people are more sensitive to differences with respect to the desirability of these consequences than to differences in the likelihood that these consequences will occur. This raises the question of whether people lack the criteria to distinguish high-quality from low-quality arguments in support of such claims. In an experiment, 196 participants without any training in argument theory rated their acceptance of 30 claims about the likelihood that a certain outcome would result from a certain action. These claims were supported by an argument from authority, or from cause to effect, or from example. Arguments were systematically manipulated to violate nine specific criteria. For seven out of the nine criteria violation decreased acceptance of the claim supported. These findings show that people can use argument type specific criteria to distinguish high- from low-quality arguments.  相似文献

Abstract

Burnout syndrome has been described by different authors as a reaction to work stress. Hence both the role stress components–role ambiguity and role conflict–appear in the literature as burnout antecedent variables. The correlation between these variables is positive. On the other hand, the work social support (from supervisors and colleagues) is a variable with influence on both role stress and burnout, so the people who perceive higher work social support feel lower role stress and lower burnout than the people who perceive lower social support. In this study we present the results of a correlational study of role ambiguity, role conflict, burnout levels (tested with Maslach Burnout Inventory), and the work social support effects on the relations. The sample are 102 nursing professionals, 24 per cent males and 76 per cent females. The results present a positive correlation between both role ambiguity and role conflict, and the emotional exhaustion scale and depersonalization scale, and a negative correlation between both role conflict and role ambiguity, and reduced personal accomplishment and work social support influence on the relations.  相似文献

Hidden economy working can provide income and cushion the financial hardship during unemployment; can it also substitute for some latent functions of regular employment? According to Jahoda's theory, the latent functions include the time structure, regular shared experience, information about personal identity, a link with the collective purpose, and enforced regular activity. This article explores whether the undeclared working reduces the degree of deprivation of these functions during unemployment and, consequently, improves the psychological health of a person. The data were collected from a sample of unemployed persons (N = 1138) registered with the Croatian Employment Bureau. A series of questions about their day-to-day activities were used to estimate the amount of undeclared working, an ad hoc developed scale to assess the extent of their latent deprivation, and the SF-36 Health Survey to measure their psychological health. The ANCOVA revealed that the participants who were often engaged in the hidden economy working exhibited reduced latent deprivation and improved psychological health compared to those who were sometimes engaged. Hierarchical regression analysis indicated that their better psychological health was partially mediated through reduced latent deprivation. However, the unemployed who were never engaged in undeclared working exhibited a relatively high psychological health as well.  相似文献

This study focuses on how converts and their close acquaintances perceive changes in personality characteristics after religious conversion and possible demographic influences of these perceptions. Sixty Slovakian respondents self-defined as having experienced conversions rated themselves twice on measures of Big Five personality traits, self-esteem, and meaningfulness in life. The first rating provided retrospective information concerning pre-conversion conditions and the second rating obtained data reflecting the convert's present self-understanding. In addition, every convert was rated on the same characteristics by someone who knew the person well during both pre- and post-conversion times. The convert and the rater both provided demographic information (age, education, religiosity, relationship to conversions and converts etc.). Analyses showed that the converts perceived several personality changes: neuroticism decreased while self-esteem, agreeableness, conscientiousness, and extraversion increased. They also reported a large increase in meaningfulness. Perceived changes were in part related to education level and age for converts, and to religiosity in both converts and close persons, suggesting a retrospective bias.  相似文献

ABSTRACT

Mild Cognitive Impairment (MCI) is characterized by episodic memory deficits, while aspects of working memory may also be implicated, but studies into this latter domain are scarce and results are inconclusive. Using a computerized search paradigm, this study compares 25 young adults, 25 typically aging older adults and 15 amnestic MCI patients as to their working-memory capacities for object-location information and potential differential effects of memory load and additional context cues. An age-related deficit in visuospatial working-memory maintenance was found that became more pronounced with increasing task demands. The MCI group additionally showed reduced maintenance of bound information, i.e., object-location associations, again especially at elevated memory load. No effects of contextual cueing were found. The current findings indicate that working memory should be considered when screening patients for suspected MCI and monitoring its progression.  相似文献

Evolutionary arms races between humans and parasites resulted in a set of behavioral adaptations that serve as parasite-avoidance mechanisms. We investigated associations among reported health of the respondent, antiparasite behavior, and sensitivity to disgust and fear of disease-relevant and irrelevant animals. Ninety-seven participants (15–19 years old) rated their fear and disgust at 25 colorful pictures of disease-relevant and disease-irrelevant invertebrates. Consistent with previous work, we found that participants reported greater fear and disgust of disease-relevant invertebrates relative to disease-irrelevant invertebrates. Better perceived health correlated with lower fear of disease-relevant invertebrates. Sensitivity to disgust correlated with reported antiparasite behaviors. Contrary to expectations, we found a positive correlation between antiparasite behavior and reported health, which suggests that antiparasite behavior influences perceived health (but not vice versa), and we found that males perform more antiparasite behaviors than females. These results support the idea that disgust and fear of disease-relevant objects are adaptive emotions that prevent contact with contagious objects, especially in individuals with low perceived health.  相似文献

The purpose of this study was to examine the role of situational and dispositional factors in contributing to competitive task involvement and performance in young tennis players. One hundred fifty-one adolescent tennis players and their coaches participated in the study. Participants responded to instruments measuring pre-game dispositional goal orientations and perceptions of the motivational climate and post-game task involvement in the competition by assessing concentration, loss of self-consciousness, and autotelic experience, perceptions of coach-initiated motivational climate in competition, and self-evaluation of game performance. In addition, coaches evaluated the players’ performance. Results showed that task involvement was predicted by players’ perceptions of a coach-initiated learning motivational climate in competition. Loss of self-consciousness was predicted by the players’ perceptions of a coach-initiated performance climate in competition. Finally, coaches’ and players’ assessment of performance were predicted by autotelic experience, concentration, and by perception of coach-initiated learning and performance orientation in competition.  相似文献

One approach to hypnosis suggests that for hypnotic experience to occur frontal lobe activity must be attenuated. For example, cold control theory posits that a lack of awareness of intentions is responsible for the experience of involuntariness and/or the subjective reality of hypnotic suggestions. The mid-dorso-lateral prefrontal cortex and the ACC are candidate regions for such awareness. Alcohol impairs frontal lobe executive function. This study examined whether alcohol affects hypnotisability. We administered 0.8 mg/kg of alcohol or a placebo to 32 medium susceptible participants. They were subsequently hypnotised and given hypnotic suggestions. All participants believed they had received some alcohol. Participants in the alcohol condition were more susceptible to hypnotic suggestions than participants in the placebo condition. Impaired frontal lobe activity facilitates hypnotic responding, which supports theories postulating that attenuation of executive function facilitates hypnotic response, and contradicts theories postulating that hypnotic response involves enhanced inhibitory, attentional or other executive function.  相似文献
