This paper asks whether persistence can be a matter of convention. It argues that in a rather unexciting de dicto sense persistence
is indeed a matter of convention, but it rejects the notion that persistence can be a matter of convention in a more substantial
de re sense. However, scenarios can be imagined that appear to involve conventional persistence of the latter kind. Since
there are strong reasons for thinking that such conventionality is impossible, it is desirable that our metaphysical-cum-semantic
theories of persistence be able to account for such scenarios in terms of conventions of the first kind. Later parts of the
article therefore investigate whether three of the currently most influential metaphysical-cum-semantic theories of persistence—the
endurance theory, the stage theory, and the perdurance theory—can do this. Fortunately, for them, it turns out that all can,
though some philosophers have disputed this. However, when we ask how they account for a typical case of “conventional persistence”
some problematic features of the theories—having to do with reference, persistence conditions, how they relate, and the epistemology
of persistence—are revealed. 相似文献

Elective cosmetic surgeries are increasing in the American population with reasons linked to body image disturbance and body dysmorphic disorder (BDD). Little research exists documenting the continuum of body image disturbance and its relationship to seeking surgery. The present research examined data from 544 participants, 55 of whom were diagnosable with BDD. Using assessments for body image disturbance, problematic coping strategies, and BDD symptomatology, results provided evidence for a continuum of body image distress. Logistic regression analysis supported the hypothesis that increased levels of body image disturbance and one type of problematic coping strategy (Appearance Fixing) predicted consideration of cosmetic surgery. Of participants diagnosable with BDD, those who considered cosmetic surgery showed more severe body image disturbance and problematic coping than those who did not consider surgery. These results have implications for pre-surgical assessment as well as psychological interventions rather than invasive medical interventions. 相似文献

Cancer patients in young adulthood are affected by the cancer diagnosis in a period of life where future parenthood or fulfilling of a potential wish to have children plays an important role. To perform fertility preserving treatment, patients should be fully informed before any treatment is carried out. The following review broaches the issue of whether and how fertility concerns are discussed in the medical consultation. Therefore, relevant papers were identified by a database search between the years 2000 and 2010. A total of 21 studies were included which focussed on physician-patient communication from the point of view of the patients or healthcare professionals. Oncologists do not routinely speak to patients about fertility issues. Both oncologists and patients expressed communication difficulties. An improvement of the medical interview concerning family planning could be achieved by provision of guidelines, training for healthcare professionals, cooperation between oncologists and reproductive medicine and the provision of educational patient material. 相似文献

This research investigated the link between ethical leadership and performance using data from the People’s Republic of China. Consistent with social exchange, social learning, and social identity theories, we examined leader–member exchange (LMX), self-efficacy, and organizational identification as mediators of the ethical leadership to performance relationship. Results from 72 supervisors and 201 immediate direct reports revealed that ethical leadership was positively and significantly related to employee performance as rated by their immediate supervisors and that this relationship was fully mediated by LMX, self-efficacy, and organizational identification, controlling for procedural fairness. We discuss implications of our findings for theory and practice. 相似文献

Reaction time (RT) and event-related potential (ERP) measures were used to examine the relationships between psychopathic
symptoms and three major attention networks (alerting, orienting, and executive attention) among a community sample of youth.
Antisocial Process Screening Device (APSD; Frick and Hare 2001) total and subscale scores were negatively correlated with ERP measures of attentional alerting, indicating that youth with
psychopathic symptoms had difficulty using warning cues to prepare for upcoming targets. APSD total scores were not related
to performance on measures of orienting or executive attention, although weaker executive attention was found among youth
with higher scores on the Impulsivity subscale. These findings support attention-based models of psychopathy and provide evidence
of specific deficits in attentional alerting among youth with psychopathic traits. Deficiencies in attentional alerting may
be related to noradrenergic functioning and may have cascading effects on higher order cognitive and affective processing. 相似文献

In addition to cognitive disability, fragile X syndrome (FXS) is associated with behavioral problems that are often functionally limiting. There are few controlled trials to guide treatment; however, available information does suggest that medications can be quite helpful for a number of categories of behavioral disturbance in FXS. Specifically, stimulants appear to be quite useful for management of distractibility, hyperactivity, and impulsive behavior; antidepressants help with anxiety, obsessive-compulsive behaviors and mood dysregulation; and antipsychotics can reduce aggression. These medications are supportive and help minimize dysfunctional behaviors and maximize functioning. As more is learned about the neural functions of FMRP, medications in the future will be expected to target specific synaptic mechanisms dysregulated in FXS brain and thus ameliorate the cognitive deficit with resultant behavioral improvements. This article summarizes knowledge about effectiveness and approaches to management of currently available psychopharmacology for behavior in FXS and discusses early leads to future treatments for cognition. 相似文献

In this study we examined the relationship between menarche and interest in infants among adolescent girls, and the effects of early environment, particularly of father absence from home, on both variables. Eighty-three girls ranging in age from between 11 and 14 years served as study participants. Interest in infants was assessed through their preferences for photos and silhouettes of animal and human faces of infants versus adults. Information on menarche and the early family environment was obtained with questionnaires and interviews. Variation in menarcheal status or timing of menarche was associated with some differences in interest in infants. There was little or no evidence, however, that suggested a direct causal relationship between these variables. Instead, both menarche and interest in infants were independently associated with early father absence from home such that father-absent girls exhibited earlier menarche and greater attraction to infant visual stimuli than father-present girls. Our results are consistent with the hypothesis that father absence is associated with a developmental trajectory characterized by earlier readiness for reproduction and parenting. 相似文献
