In debates about rationalizing action explanation causalists assume that the psychological states that explain an intentional action have both causal and rational features. I scrutinize the presuppositions of those who seek and offer rationalizing action explanations. This scrutiny shows, I argue, that where rational features play an explanatory role in these contexts, causal features play only a presuppositional role. But causal features would have to play an explanatory role if rationalizing action explanation were a species of causal explanation. Consequently, it is not a species of causal explanation. 相似文献

Transcranial direct current stimulation (tDCS) over the primary motor cortex (M1) can boost motor performance in Parkinson’s disease (PD) when it is applied at rest. However, the potential supplementary therapeutic effect of the concurrent application of tDCS during the training of motor tasks is largely unknown. The present study examined the effects of tDCS on upper limb motor blocks during a freezing-provoking writing task (the funnel task) requiring up- and down-stroke movements at alternating amplitudes. Ten PD patients and 10 age-matched controls underwent two sessions of writing combined with 20 min of anodal or sham tDCS on the left M1 in a randomized cross-over design. The primary outcome was the number of upper limb freezing episodes during five trials of the funnel task on a touch-sensitive tablet. PD patients showed a significant reduction in freezing episodes during tDCS compared to sham. No effects of tDCS were found for the amplitude, variability and speed of the strokes outside the freezing episodes. However, patients who reported freezing episodes in daily life (N = 6) showed a beneficial effect of tDCS on stroke characteristics. These results indicate a subgroup-dependent variability in response to non-invasive brain stimulation applied during the performance of motor tasks in PD. This warrants future studies to examine tDCS as an adjuvant tool for training programs aimed to reduce motor deficits related to freezing. 相似文献

基于推荐系统中协同过滤推荐的思想, 提出两种可以利用已有答题者数据的CAT选题策略:直接基于答题者推荐(DEBR)和间接基于答题者推荐(IEBR)。通过两个模拟研究, 在不同题库和不同长度的测验中, 比较了两种推荐选题策略与两种传统选题策略(FMI和BAS)在测量精度和对题目曝光率控制上的表现, 以及影响推荐选题策略表现的因素。结果发现:两种推荐选题策略对题目曝光率的控制优于两种传统选题策略, 测量精度不亚于BAS方法, 其中DEBR侧重选题精度, IEBR对题目曝光率控制最好。已有答题者数据的特点和质量是影响推荐选题策略表现的主要因素。 相似文献

The aim of this study is to investigate the effectiveness of student counseling in Denmark and to compare the symptomatic distress among student counseling clients with that of Danish outpatients. The pre-intervention level of self-reported symptomatic distress among 1256 students closely paralleled that of psychiatric outpatients. Participants in the intervention study were the 739 student clients with two or more counseling sessions. For the 530 (71.7%) participants with both pre- and post-measurements, the mean pre–post Cohen’s d effect size (ES) was .76 on the Global Severity Index of the Symptom Check List-90-Revised. An intention-to-treat analysis of all 739 clients resulted in an ES of .59. The number of recovered clients according to the Jacobson and Truax criteria was 295 (68.8%) of the 429 (80.9%) clients above the clinical cut-off at pre-intervention, while 66 (12.5%) of the 530 clients reliably deteriorated. The mean number of sessions was 5.0. Individual counseling, number of sessions, and ending counseling in agreement predicted better outcome. In line with results from other countries, this study may indicate that in Denmark student counseling is an effective intervention for a highly needy clientele, even though a high proportion of clients deteriorated (12.5%) or dropped out (31.7%). 相似文献

Transgender and gender diverse (TGD) populations, including those that do not identify with gender binary constructs (man or woman) are increasingly presenting for treatment of posttrauma sequelae. Providers who offer services for trauma survivors including posttraumatic stress disorder (PTSD) treatment should be knowledgeable about evidence-based care and have some cultural familiarity with TGD experiences. Indeed, the Minority Stress Model suggests that the combination of distal and proximal minority stressors can combine to produce increased mental health symptoms as compared with cisgender peers, though this model has yet to be fully tested. Clients often present with a complicated picture of experiences, which include a variety of minority stressors, microaggressions, discrimination, and traumatic events that can all be related to their identity. However, conceptualizations of trauma treatment in the context of extensive minority stress are lacking. This paper summarizes the existing literature and offers guidance to mental health providers who are well positioned to address stigma, discrimination, violence, and related symptoms that arise from micro-, mezzo- and macro-level spheres of TGD individuals’ experience. 相似文献

The platonic dialogue, Symposium, is approached here through client work. This rich and complex text is not rushed through as if the point of a conversation must be its swift and clear termination, rather than how potentially fruitful, generative and transformative it is or may come to be when we reflect or engage in further conversation. This paper suggests that Symposium presents us with two ways of thinking about relating to another, and ends with some remarks about this platonic dialogue and psychotherapy that could, of course, be followed by more conversation. 相似文献

This paper presents the Modified Grey Wolf Optimization (MGWO) algorithm which helps with the identification of the symptoms of Parkinson’s disease at a premature stage. Parkinson disease is kind of a movement malady, which if not cured timely can prove to be fatal.Thus it becomes significant to identify Parkinson’s disease at its premature phase so proper medications can provide longevity to patient by controlling the symptoms. In this work, a new model named Modified Grey Wolf Optimization (MGWO) has been proposed grounded on the traditional Grey Wolf Optimizer (GWO), which acts as a search strategy for feature selection. GWO is a meta-heuristic algorithm which is enthused by hunt down behavior of wolves. Random forest, k-nearest neighbor classifier and decision tree espy on selected features. The proposed model is evaluated using various types of datasets of voice, handwriting (spiral and meander) and speech. The put forward algorithm helps in the prediction of Parkinson disease with an estimated accuracy of 94.83%, detection rate of 98.28%, false alarm rate of 16.03% and further aid the individuals to receive a functional treatment at an early stage. The proposed bio-inspired algorithm is stable enough to find out the optimal subset of features. At last the results derived from the evaluation of proposed algorithm on datasets are compared with the results of Optimized Cuttlefish Algorithm (OCFA). The experimental results depict that the proposed algorithm helps in maximizing the accurateness and minimizing the number of features selected. 相似文献

Even though we are on the precipice of a “bad Anthropocene,” humankind should not colonize Mars. Mars is often depicted as our “Planet B”—an evacuation plan for Earth. But in this time of ecological crisis, theologian Sallie McFague suggests that we think of the Earth as God’s body and take our obligation to care for our common home seriously. Likewise, in contrast to calls for colonization, I contend that two American historical anecdotes—the safety valve theory and the Yellowstone—illustrate why humanity should think less about becoming Martians and instead find meaning and purpose in remaining Earthlings. 相似文献
