We discuss in this paper the scope of abduction in Economics. The literature on this type of inference shows that it can be interpreted in different ways, according to the role and nature of its outcome. We present a formal model that allows to capture these various meanings in different economic contexts. 相似文献

This longitudinal study was conducted among 102 women with non-metastasic breast cancer to identify the time evolution and prevalence of distress at specific times through diagnosis and treatment of disease: preliminary diagnosis, surgery, definitive diagnosis and chemotherapy. Additionally, the study aimed to examine the role of demographic, medical and psychosocial factors on distress. The results indicated that prevalence of distress was higher at initial diagnosis (25%) than the following time points (approximately 17%). The differences inter-individuals in the levels of distress were observed over the four assessments. No relation between distress and demographic and medical factors was found. However, psychosocial aspects were significant risk factors. Patterns of emotional suppression and specific coping responses like helplessness/hopelessness, anxious preoccupation, cognitive avoidance and fatalism were positively related to distress, whereas fighting spirit and perceived social support showed a protective role. Moreover, helplessness/hopelessness and anxious preoccupation jointly predicted 75% of cases and 98% non-cases of distress. Finally, a mediational model between emotional suppression and distress through helplessness/hopelessness was tested. Results support the necessity of routine distress screening all through the illness. Implications of data for psychosocial interventions with breast cancer patients are highlighted. 相似文献

The acceptance of migrant populations and the definition of an “appropriate” migrant are controversial issues in many countries. The present research focuses on the ideological determinants of how newcomers are evaluated by a host population in a Western country with a strongly rooted meritocratic ideology. We carried out two studies to examine how the expression of meritocratic beliefs by a male potential migrant affects the way he is evaluated by the host population. We measured the host population's perception of the potential migrant's ability to integrate into society, his tendency to adopt the host country's culture, and the general desirability of his world vision for all newcomers. We also noted the host population's judgments of the target's agency and communality. The results showed that a potential newcomer who expresses a strong (vs. weak) belief in a just world (Study 1) or an internal (vs. external) locus of control (Study 2) is evaluated more favorably by the host population. In addition, judgments of the target's integration capacity were only mediated by his perceived agency. We discuss these results in the light of work on the meritocratic ideology and intercultural relations. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

We assessed whether certain life events contributed to the communication about cancer risk within families who have undergone BRCA1/2 testing. We also explored what type of resources participants would have valued to help in supporting family communication about genetic information. Two hundred and forty-six individuals (218 women, 28 men) who received a BRCA1/2 genetic test result 3 to 10 years earlier (mean of 6.4 years) participated in a telephone interview. Participants were asked about the occurrence of a number of life events (cancer diagnosis, death, uptake of prophylactic surgery, and providing care to a family member with cancer) in their family since their BRCA1/2 test result disclosure and, for each occurrence, whether it fostered family communication about cancer risk. A total of 182 participants (74 %) reported that they or one of their relatives received a cancer diagnosis, 176 (72 %) reported that someone died in their family, and 73 (30 %) stated that they or one of their relatives undertook a prophylactic surgery. During this period, 109 participants (44 %) also provided care for a family member who had cancer. Among participants who reported these life events, family communication was fostered by these events in proportions varying from 50 % (death) to 69 % (cancer diagnosis). Our results indicate that life events may contribute to family communication about cancer risk. Further research is needed to determine whether these events provide a “window of opportunity” to reach family members, address their needs and concerns about cancer, update family cancer history, and introduce genetic counseling and risk assessment. 相似文献

Enhanced pitch perception and memory have been cited as evidence of a local processing bias in autism spectrum disorders (ASD). This bias is argued to account for enhanced perceptual functioning (Mottron &; Burack, 2001; Mottron, Dawson, Soulières, Hubert, &; Burack, 2006) and central coherence theories of ASD (Frith, 1989; Happé &; Frith, 2006). A local processing bias confers a different cognitive style to individuals with ASD (Happé, 1999), which accounts in part for their good visuospatial and visuoconstructive skills. Here, we present analogues in the auditory domain, audiotemporal or audioconstructive processing, which we assess using a novel experimental task: a musical puzzle. This task evaluates the ability of individuals with ASD to process temporal sequences of musical events as well as various elements of musical structure and thus indexes their ability to employ a global processing style. Musical structures created and replicated by children and adolescents with ASD (10–19 years old) and typically developing children and adolescents (7–17 years old) were found to be similar in global coherence. Presenting a musical template for reference increased accuracy equally for both groups, with performance associated to performance IQ and short-term auditory memory. The overall pattern of performance was similar for both groups; some puzzles were easier than others and this was the case for both groups. Task performance was further found to be correlated with the ability to perceive musical emotions, more so for typically developing participants. Findings are discussed in light of the empathizing-systemizing theory of ASD (Baron-Cohen, 2009) and the importance of describing the strengths of individuals with ASD (Happé, 1999; Heaton, 2009). 相似文献

The purpose of this study was to investigate the moderating effect of having vs. not having a and quality of life. In-person interviews were conducted with 55 male and 64 female inmates from the Topas Penitentiary (Spain). Higher levels of social loneliness and lower levels of sexual satisfaction were associated with lower levels of quality of life. In addition, the interaction between sexual satisfaction and romantic partner status was significant. Higher levels of sexual satisfaction were associated with higher levels of quality of life only for the group without a partner. These findings support a "bad is stronger than good" principle and indicate the detrimental aspects that can be associated with not having a satisfactory sexual life while incarcerated. 相似文献

This study analyzes the prevalence and characteristics of childhood and adolescence sexual abuse suffered by a sample of university students, as well as the variables associated with the nature of abuse. Participants anonymously completed the Questionnaire on Child Sexual Abuse, in order to obtain information about experience of sexual abuse. Of a total of 2,375 students, 289 (12.2%) declared having suffered sexual abuse before the age of 18. The invasiveness, continuity, and severity of abuse was related to the location where the abuse took place (the more severe cases were committed in the homes of the victim and perpetrator) and to the circumstances of abuse (relationships with partners/at a party or while caring for a child predicted more severe abuse). The age of the victim (preschool) and an intrafamilial relationship between victim and perpetrator were also related to more invasive, continuous, and severe sexual abuse. The knowledge of characteristics of perpetrator and victim and the context in which sexual abuse occurs can help to better comprehend the nature and correlates of sexual abuse. The results of the present study may contribute to the design of programs for the prevention of sexual abuse to minors. 相似文献

Computational models of cognitive aging propose that age-related decrements in cognitive performance, including short-term memory (STM), result from less distinct stimulus representations. When applied to visual STM, these models predict higher discriminal dispersion (L. L. Thurstone, 1927, Psychophysical analysis, The American Journal of Psychology, 38, 368-389.) in older adults than in younger adults. To test this prediction, we used a change-detection paradigm for visuospatial locations, with different levels of cognitive load (one, three, or five items) and retention interval (100 or 1,000 ms). Adult age differences were not reliable at Load 1, but were substantial at Loads 3 and 5. Effects of retention time did not differ across age groups, suggesting that age-related differences originated mainly from early processing stages. Applying a mixture model to the data revealed age-related increases in discriminal dispersion and decreases in asymptotic discrimination performance (indexing STM capacity). We concluded that age-related declines in discriminal dispersion, in addition to increasing capacity limitations, impair visual STM performance with advancing adult age.

Recent investigations of early psychological understanding have revealed three key findings. First, young infants attribute goals and dispositions to any entity they perceive as an agent, whether human or non-human. Second, when interpreting an agent's actions in a scene, young infants take into account the agent's representation of the scene, even if this representation is less complete than their own. Third, at least by the second year of life, infants recognize that agents can hold false beliefs about a scene. Together, these findings support a system-based, mentalistic account of early psychological reasoning. 相似文献
