An impossibility result pertaining to the aggregation of individual judgements is thought by many to have significant implications for political theory, social epistemology and metaphysics. When members of a group hold a rational set of judgments on some interconnected questions, the theorem shows, it isn’t always (logically) possible for them to aggregate their judgements into a collective one in conformity with seemingly very plausible constraints. I reject one of the constraints which engender the dilemma. The analogy with the lottery paradox, I argue, shows that rational belief needn’t be consistent. So the alleged implications of the dilemma are dispelled.  相似文献

The current study examines 16 Latina/o fifth grade children's desires for a decision-making structure within a youth participatory action research (yPAR) program. When given the choices of consensus, majority rule, authoritarian rule, delegation, and random choice models, children chose random choice. Procedural, distributive and emotional justice were heavily weighted in their reasoning around fairness and decision making. Many thought random choice offered the best alternative because it flattened power hierarchies so that each child would, at some point, have the power to make a decision. Additionally, children argued that the neutrality of random choice allowed them to sidestep interpersonal tensions. Implications include how social identities inform definitions of fairness and how yPAR programs should work with youth around how they will make decisions.  相似文献

Anger is an intense and adaptive approach emotion that undergoes significant development during the toddler years. We assessed the expression of anger and the strategies toddlers use to regulate it in relation to maternal behavior and mental representations. Seventy-four toddlers were observed in three anger-eliciting paradigms: toy removal (TR), still-face (SF), and delayed gratification (DG). Anger expression and three clusters of regulatory behaviors were micro-coded: putative regulatory behaviors, attention manipulation, and play behaviors. Maternal relational style was coded for sensitivity and intrusiveness, and mental representations of the mother-child relationship were assessed for joy and anger. Children expressed the most anger during the TR, less during the SF, and minimally during the DG. Use of putative regulatory behaviors was highest during the SF, whereas during the TR children employed newly acquired skills, such as focused attention and substitutive play, in the service of anger regulation. Anger expression and regulation were differentially related to the negative and positive components in the mother's behavior and representations, and maternal intrusiveness moderated the relations between angry representations and the degree of child anger during the SF. Results are consistent with dynamic models of emotions and accord with perspectives that emphasize the role of sensitive parenting in facilitating emotion regulation.  相似文献

Erich Fromm (1900?C1980) was a co-founder of the Frankfurt Psychoanalytic Institute and the William Alanson White Institute in New York and finally he founded a training institute of his own in Mexico. However, he never intended to create a therapeutic school of his own. Furthermore, he published hardly anything about the so-called psychoanalytic techniques. All the more informative is the report of Ruth Lesser about her supervisions with Fromm. She describes how Fromm reacted to the presented cases, what kind of a role repression, resistance, transference and countertransference play in the therapeutic relationship and how strongly interested he was in the socially shaped unconscious intentions of the patient. The straightforwardness of the intervention style of Fromm is impressively described both in his empathy and in his confrontation with the unconscious reality. In the last part of the article Fromm??s understanding of the psychoanalytic situation is reflected and the characteristics of his psychoanalytic treatment method are outlined.  相似文献

We examined the associations between parental educational/occupational levels and cognitive performance in Spanish adolescents. Cognitive performance was measured by a validated Scholar Aptitudes test in 2,162 participants. Parental educational and occupational levels were positively associated with all specific cognitive abilities and the overall score (p<001 to .04). The odds ratios of having a high cognitive performance (top quartile) in adolescents with high parental educational level were 1.6 to 1.7 times higher than for those with a low parental educational level. Similarly, the odds ratios were 1.9 to 2.4 times higher for adolescents with high parental occupational level. These findings suggest an association between parental educational/occupational levels and cognitive performance in Spanish adolescents and support the parents' role in the creation of a stimulating intellectual environment.  相似文献

Objective

The goal of the present study was to examine distributed attentional functions in long-term but currently abstinent methamphetamine (MA) abusers using a task that measures attentional alertness, orienting, and conflict resolution.

Methods

Thirty currently abstinent MA abusers (1 month-5 years) and 22 healthy non-substance using adults were administered a multimodal version of the Attentional Network Task (ANT-I). In this task subjects identified the direction of a centrally presented arrow using a key press. Analyses examined the interaction between alerting tones, location cueing and congruency between the target arrows and flanking distractor stimuli.

Results

All participants were faster when an auditory tone preceded the trial onset (p < 0.001), on trials in which a valid cue preceded the location of the target arrow (p < 0.001), and on congruent trials (i.e., when all display arrows faced in the same direction) (p < 0.001). Of primary interest was the finding that MA abusers were more influenced by the conflict between the peripheral arrows and the central target arrow (p = 0.009). There were also correlations between length of drug sobriety and executive function as well as between drug-induced psychiatric symptoms and alertness.

Conclusions

These results suggest that chronic MA abusers display cognitive deficits that may reflect a specific vulnerability to distraction on a task of executive function. These findings are consistent with other studies that have reported deficits in anterior attentional systems and top-down cognitive control.  相似文献

With the completion of the Human Genome Project and the development of high throughput technologies, such as next-generation sequencing, the use of multiplex genetic testing, in which multiple genes are sequenced simultaneously to test for one or more conditions, is growing rapidly. Reflecting underlying heterogeneity where a broad range of genes confer risks for one or more cancers, the development of genetic cancer panels to assess these risks represents just one example of how multiplex testing is being applied clinically. There are a number of issues and challenges to consider when conducting genetic testing for cancer risk assessment, and these issues become exceedingly more complex when moving from the traditional single-gene approach to panel testing. Here, we address the practical considerations for clinical use of panel testing for breast, ovarian, and colon cancers, including the benefits, limitations and challenges, genetic counseling issues, and management guidelines.  相似文献

There is a large gulf between what psychiatric services should (or could) provide and what they do in practice. This article sought to determine practice differences between the differing professions working in adult mental health services in terms of their family focused work. Three hundred and seven adult mental health professionals completed a cross‐sectional survey of family focused practices in adult mental health services. Findings highlight that social workers engaged in more family focused practice compared to psychiatric nurses, who performed consistently the lowest on direct family care, compared to both social workers and psychologists. Clear skill, knowledge, and confidence differences are indicated between the professions. The article concludes by offering direction for future profession education and training in family focused practices.  相似文献
