This study examined the perceptual attunement of relatively skilled individuals to the physical properties of striking implements in the sport of cricket. We also sought to assess whether utilizing bats with different physical properties would influence performance of a specific striking action: the front foot straight drive. Eleven skilled male cricketers (mean age = 16.6 ± 0.3 years) from an elite school cricket development program consented to participate in the study. While blindfolded, participants wielded six bats exhibiting different mass and moment of inertia (MOI) characteristics and were asked to identify the three bats they preferred the most for hitting a ball to a maximum distance by performing a front foot straight drive (a common shot in cricket). Next, participants actually attempted to hit balls projected from a ball machine using each of the six bat configurations to enable kinematic analysis of front foot straight drive performance with each implement. Results revealed that, on first choice, the two bats with the smallest mass and MOI values (1 and 2) were most preferred by almost two thirds (63.7 %) of the participants. Kinematic analysis of movement patterns revealed that bat velocity, step length, and bat–ball contact position measures significantly differed between bats. Data revealed how skilled youth cricketers were attuned to the different bat characteristics and harnessed movement system degeneracy to perform this complex interceptive action. 相似文献

Investigation of the amnesic disorder Korsakoff Syndrome (KS) has been vital in elucidating the critical brain regions involved in learning and memory. Although the thalamus and mammillary bodies are the primary sites of neuropathology in KS, functional deactivation of the hippocampus and certain cortical regions also contributes to the chronic cognitive dysfunction reported in KS. The rodent pyrithiamine-induced thiamine deficiency (PTD) model has been used to study the extent of hippocampal and cortical neuroadaptations in KS. In the PTD model, the hippocampus, frontal and retrosplenial cortical regions display loss of cholinergic innervation, decreases in behaviorally stimulated acetylcholine release and reductions in neurotrophins. While PTD treatment results in significant impairment in measures of spatial learning and memory, other cognitive processes are left intact and may be recruited to improve cognitive outcome. In addition, behavioral recovery can be stimulated in the PTD model by increasing acetylcholine levels in the medial septum, hippocampus and frontal cortex, but not in the retrosplenial cortex. These data indicate that although the hippocampus and frontal cortex are involved in the pathogenesis of KS, these regions retain neuroplasticity and may be critical targets for improving cognitive outcome in KS. 相似文献

While acknowledging a certain affinity between his own thought and the Vedanta concept of a world-soul or universal spirit, Josiah Royce nevertheless locates this concept primarily in what he terms the Second Conception of Being—Mysticism. In his early magnum opus, The World and the Individual (1990. New York, NY: Macmillan), Royce utilizes aspects of the Upanishads in order to flesh out his picture of the mystical understanding of and relationship to being. My primary concern in the present investigation is to introduce some nuance into Royce’s conception of Indian thought, which may then serve to suggest similar possibilities for nuance for Royce’s conception of the Absolute. I will attempt to do in two primary ways: first, I will consider Royce’s use of Indian thought via the Upanishads in explicating his second historical conception of Being. I will then turn briefly to Emerson’s poem ‘Brahma’ and the Bhagavad Gita to see if a certain reversal that occurs in both places problematizes Royce’s depiction of the universal spirit in Indian thought as well as opens up new possibilities for Royce’s own Absolute. 相似文献

In this study we examine two assumptions that underlie the hypothesis that the outcomes of children with emotional disturbances are negatively affected by the loss of access to mental health services during their transitions to adulthood. The first is that children access mental health services during the pre-transition years, and the second is that these services are effective in reducing poor outcomes. We tested these assumptions using children who lost Medicaid enrollment between their 18th and 20th birthdays in Florida’s Medicaid program using arrests as the outcome. All children with an emotional disturbance received at least one outpatient service. However, while the mean days of service per month were 3, more than half the children received less than one day of service. Fifty-six percent of children received some psychotherapeutic medication treatment. Children with ADHD had the highest number of days of medication per month in both univariate and multivariate analysis. In multivariate analysis, children with disruptive behavior disorders had significantly more days per month of outpatient services than children with any other diagnoses except anxiety disorders. Medication days but not outpatient service days were negatively associated with arrests. Post hoc analysis suggested that children with ADHD who had high medication days had significantly fewer arrests than children with disruptive behavior disorders. This was not the case for children with ADHD and low medication days. Children with ADHD and high medication use may be most at risk of increases in arrests after Medicaid disenrollment as many will lose access to a service that was associated with fewer arrests. Findings suggest the need for reform of the children’s mental health system. 相似文献

This study analyzed the promotion of sexual health and sexual responsibility in Women’s Health and Men’s Health magazines as characterized by the Surgeon General’s Call to Action along with sexual health objectives targeted by Healthy People 2020 and sexual healthy behavior outcomes established by the Centers for Disease Control and Prevention. This study also identified the most frequently addressed sexual health topics included in Women’s Health and Men’s Health. Two coders conducted a content analysis of a total of 599 articles from 64 issues (32 Women’s Health and 32 Men’s Health) published between January 2009 and November 2012. More than half of all articles addressing sexual health were found to promote sexual health (57 %). Promotion of sexual responsibility was rare with variables such as ensuring that pregnancy occurs only when desired, recognition and tolerance for diversity, limiting the number of sexual partners, and using birth control consistently each mentioned in <3 % of articles in this study sample. Among topics coded, improving sex life (29 %), what men like (19 %), and what women like (18 %) were the most common in Women’s Health while What women like (46 %), improving sex life (27 %), and other men’s sexual health (16 %) were the most frequent topics in Men’s Health. Among the least common topics mentioned were homosexuality (0.16 %) and HIV/AIDS (0.33 %). No articles addressed rape or dating violence. 相似文献

The United Nations (UN) Universal Declaration of Human Rights engenders important state commitments to respect, fulfill, and protect a broad range of socio-economic rights. In 2010, a milestone was reached when the UN General Assembly recognized the human right to safe and clean drinking water and sanitation. However, water plays an important role in realizing other human rights such as the right to food and livelihoods, and in realizing the Convention on the Elimination of All Forms of Discrimination against Women. These broader water-related rights have been recognized but have not yet been operationalized. This paper unravels these broader water-related rights in a more holistic interpretation of existing international human rights law. By focusing on an emerging approach to water services provision—known as ‘domestic-plus’ services—the paper argues how this approach operationalizes a comprehensive range of socio-economic rights in rural and peri-urban areas. Domestic-plus services provide water for domestic and productive uses around homesteads, which challenges the widespread practice in the public sector of planning and designing water infrastructure for a single-use. Evidence is presented to show that people in rural communities are already using their water supplies planned for domestic uses to support a wide range of productive activities. Domestic-plus services recognize and plan for these multiple-uses, while respecting the priority for clean and safe drinking water. The paper concludes that domestic-plus services operationalize the obligation to progressively fulfill a comprehensive range of indivisible socio-economic rights in rural and peri-urban areas. 相似文献
