Event-causal libertarians maintain that an agent’s freely bringing about a choice is reducible to states and events involving him bringing about the choice. Agent-causal libertarians demur, arguing that free will requires that the agent be irreducibly causally involved. Derk Pereboom and Meghan Griffith have defended agent-causal libertarianism on this score, arguing that since on event-causal libertarianism an agent’s contribution to his choice is exhausted by the causal role of states and events involving him, and since these states and events leave it open which decision he will make, he does not settle which decision occurs, and thus “disappears.” My aim is to explain why this argument fails. In particular, I demonstrate that event-causal libertarians can dismantle the argument by enriching the reductive base in their analysis of free will to include a state that plays the functional role of the self-determining agent and with which the agent is identified.  相似文献

Current understandings of racism and race talk within discourse analytic traditions have largely focused on the discursive construction and perpetuation of dominance, prejudice, and racism within majority and privileged groups. Although minorities are often the objects of these studies, these research traditions have not extensively studied the language of race talk in minority groups. This article aims to integrate ‘bottom‐up’ approaches of minority and marginalized groups' discourses to discursive psychological and critical discourse analysis theory and research on race talk. The paper begins with a short review of the current discourse analytic frameworks utilized in the analysis of race talk. Next, the paper outlines several ‘bottom‐up’ research examples and concludes by offering several important insights. It is argued that the absence of minority discourses runs the danger of reproducing and reinforcing the very things discourse analysis aims to uncover and problematize. The main conclusion of this paper is that the insights from the ‘bottom‐up’ point to the necessity of broader theorizing around the discursive construction of race talk.  相似文献

Systematic observational studies of the chaplain's role and function in the secular health‐care setting are few. With an episode‐based diary recorded on handheld digital tablets, palliative care chaplains at a large urban hospital with a diverse patient population recorded details of patient visits in near‐real time. Cluster analysis revealed groups of activities we called \"doing\" and \"being,\" and conversation topics of \"practical matters\" and \"ultimate concerns”; chaplains were most satisfied with visits that involved all of these. Chaplains offer patients and families a space to express significant concerns; however, visits with spiritual or religious activities or topics were relatively rare. Broad quality of life concerns are central to the evolving professional role of chaplains in the secular setting of the modern hospital.  相似文献

ABSTRACT

Knowledge of cross-informant rating concordance is critical for the assessment of child and adolescent problems in clinical and research settings. We explored parent-youth rating concordance for hair pulling variables, functional impairment, and anxiety symptoms in a sample of child and adolescent hair pullers (n = 133) satisfying conservative diagnostic criteria for trichotillomania (TTM). Whole group analyses reveal significant parent-youth agreement on all study variables. Split group analyses, however, reveal superior parent-youth concordance for the adolescent (15–17 years old) versus younger (10–12 years old) hair pullers for awareness of hair pulling and anxiety scale scores. These results highlight the need for both parent and youth ratings when assessing younger children with TTM.  相似文献

Abstract

This article integrates an ecological approach and design-based research in computer science education research by following the simultaneous development of a computer programming environment and curriculum for elementary school age children over 2-1/2 years. We studied the alignment of the affordances provided by the programming environment and curriculum with the effectivities of students in 4th through 6th grade (9-12 years old). We used the computer science concept of initializing as a tracer idea and both qualitative and quantitative data to identify mismatches between the affordances provided by our programming environment and the learners’ effectivities. These included requisite mathematical skills, confusion between resetting and setting up, and incorrectly assuming that features of the programming environment conveyed information. We then describe how we addressed the mismatches by removing or adding functionality to the programming environment, adding signifiers, adapting the curriculum to include scaffolding related to the effectivities, or removing activities.  相似文献

In the present study, we examined the psychometric properties of the Skin Picking Impact Scale (SPIS; Keuthen, Deckersbach, Wilhelm et al., 2001), a 10 item self‐report questionnaire designed to assess the psychosocial impact of skin picking disorder (SPD). Participants were 650 individuals who met criteria for SPD in an online survey. Exploratory and confirmatory factor analyses demonstrated a unitary factor structure with high internal consistency (α = 0.94). Consequently, we constructed an abbreviated 4‐item version that retained good internal consistency (α = 0.87) and a robust factor structure. Both the short and the full versions demonstrated discriminant and convergent/concurrent validity. In conclusion, the findings indicate that both versions are psychometrically sound measures of SPD related psychosocial impact; however, some potential limitations of the full scale are discussed.  相似文献

Adolescent decision‐making has been described as impulsive and suboptimal in the presence of incentives. In this study we examined the neural substrates of adolescent decision‐making using a perceptual discrimination task for which small and large rewards were associated with correctly detecting the direction of motion of a cloud of moving dots. Adults showed a reward bias of faster reaction times on trials for which the direction of motion was associated with a large reward. Adolescents, in contrast, were slower to make decisions on trials associated with large rewards. This behavioral pattern in adolescents was paralleled by greater recruitment of fronto‐parietal regions important in representing the accumulation of evidence sufficient for selecting one choice over its alternative and the certainty of that choice. The findings suggest that when large incentives are dependent on performance, adolescents may require more evidence to accumulate prior to responding, to be certain to maximize their gains. Adults, in contrast, appear to be quicker in evaluating the evidence for a decision when primed by rewards. Overall these findings suggest that rather than reacting hastily, adolescents can be incentivized to take more time to make decisions when large rewards are at stake.

Violence in military families remains a vexing problem. Since the advent of the Global War on Terror, there is inconsistent evidence that the prevalence of family violence is increasing, particularly during and after military deployments. However, child neglect appears to increase significantly during military deployments. The military has developed family advocacy programs designed to keep families safe and intervene to reduce the deleterious effects of exposure to family violence. This is one of the first studies to examine the quality with which a family advocacy program is implemented and the degree to which families engage with the program. To conduct this study, the case files of 226 families who came in contact with the Army Family Advocacy Program (FAP) and whose cases were closed in 2013 were reviewed and coded across several implementation and service outcomes. These included involvement of qualified staff, whether or not appropriate victim and offender assessments were completed, degree of inter-agency communication, and appropriateness of referrals, among others. Soldier and family member participation in FAP and other Army-sponsored programs designed to reduce violence was also assessed. Generally speaking, the Army Family Advocacy Program was implemented with high quality, established processes and procedures for handling cases were largely followed, and FAP staff responded rapidly and thoroughly to reported abuse. However, family engagement with Army services and supports was low. Developing robust approaches to engaging families in family programming must be a high priority going forward.  相似文献

Recall decreases across a series of subspan immediate-recall trials but rebounds if the semantic category of the words is changed, an example of release from proactive interference (RPI). The size of the rebound depends on the semantic categories used and ranges from 0% to 95%. We used a corpus of novels to create vectors representing the meaning of about 40,000 words using the BEAGLE algorithm. The distance between categories and spread within categories jointly predicted the size of the RPI. We used a holographic model for recall equipped with a lexicon of BEAGLE vectors representing the meaning of words. The model captured RPI using a hologram as an interface to bridge information from episodic and semantic memory; it is the first account of RPI to capture release at the level of individual words in categorized lists.  相似文献

Physical activity has been shown to benefit cancer survivors' physical functioning, emotional well-being, and symptoms. Physical activity may be of particular benefit to survivors of endometrial cancer because they are more likely to be obese and sedentary than the general population, as these are risk factors for the disease, and thus experience a number of related co-morbid health problems. However, there is little research systematically studying mechanisms of physical activity adherence in cancer survivor populations. This paper describes the design of the Steps to Health study, which applies a Social Cognitive Theory-based model of endometrial cancer survivors' adoption and maintenance of exercise in the context of an intervention to increase walking or other moderate intensity cardiovascular activity. In Steps to Health we will test the influence of self-efficacy and outcome expectations on adherence to exercise recommendations, as well as studying the determinants of self-efficacy. Endometrial cancer survivors who are at least 6 months post-treatment are provided with an intervention involving print materials and telephone counseling, and complete assessments of fitness, activity, self-efficacy and outcome expectations, and determinants of self-efficacy every two months for a six month period. In addition to testing an innovative model, the Steps to Health study employs multiple assessment methods, including ecological momentary assessment, implicit tests of cognitive variables, and ambulatory monitoring of physical activity. The study results can be used to develop more effective interventions for increasing physical activity in sedentary cancer survivors by taking into account the full complement of sources of self-efficacy information and outcome expectations.  相似文献
