BackgroundStochastic resonance stimulation (SRS) transmits subsensory electrical Gaussian white noise into the body to enhance sensorimotor function. This therapy has improved static single leg balance in subjects with functional ankle instability. However, the effect of this stimulation on dynamic single leg balance is not known. Improvements in dynamic single leg balance with SRS may have implications for enhancing functional rehabilitation for ankle instability. Thus, the purpose of this study was to determine the effects of SRS on dynamic single leg balance in subjects with functional ankle instability.MethodsThis study was an experimental research design and data were collected in a sports medicine research laboratory. Twelve subjects with functional ankle instability (69 ± 15 kg; 173 ± 10 cm; 21 ± 2 years) reported a history of ankle sprains and instability at the ankle with physical activity. A single leg jump-landing test was used to assess dynamic balance. Subjects were required to jump between 50% and 55% of the maximal vertical jump height, land on a single leg atop a force plate, and stabilize as quickly as possible. Jump-landing tests were performed with and without SRS. Three trials were performed for each treatment condition (SRS and control). A randomized block design was used to determine test order. Anterior/posterior and medial/lateral time-to-stabilization were computed to assess dynamic balance. Lesser time indicated better stability. One-tailed paired samples t tests were used for analysis (α ≤ 0.05).ResultsSRS improved anterior/posterior time-to-stabilization (stochastic resonance = 1.32 ± 0.31 s, control = 1.74 ± 0.80 s, p = 0.03), but did not enhance medial/lateral time-to-stabilization (stochastic resonance = 1.95 ± 0.40 s, control = 1.92 ± 0.48 s, p = 0.07).ConclusionClinicians might use SRS to facilitate balance improvements with sagittal plane dynamic single leg balance exercises that patients may not be able to perform otherwise. 相似文献

Mobile messaging systems, particularly those that incorporate social networking capabilities, affect how individuals socially interact and how they exchange information. This paper reports the impact of a mobile-device-based social networking service that enables users to form groups and send both text and photos to co-members. Survey and system usage data from 19 participants over 16 months were analyzed using information ground theory, which focuses on how people share everyday information in informal social settings. This study was novel in applying the theory to an online environment. In addition to how the mobile system functions as an information ground, the results highlight the types and usefulness of information shared, the role of information shared in everyday life, and how the system fits into participants' communication and social “ecosystem.” Usage analyses describe message sending frequency and system participation levels in relation to other factors, such as length of time in the system. Findings are discussed in the context of the information ground framework's seven propositions, to which we propose adding an emergent concept: “information capital,” i.e., an individual's capacity to access information based on his/her information grounds extent, and degrees of social capital and information literacy. 相似文献

Inborn errors of metabolism (IEM) include a broad spectrum of defects of various gene products that affect intermediary metabolism in the body. Studying the molecular and biochemical mechanisms of those inherited disorder, systematically summarizing the disease phenotype and natural history, providing diagnostic rationale and methodology and treatment strategy comprise the context of human biochemical genetics. This session focused on: (1) manifestations of representative metabolic disorders; (2) the emergent technology and application of newborn screening of metabolic disorders using tandem mass spectrometry; (3) principles of managing IEM; (4) the concept of carrier testing aiming prevention. Early detection of patients with IEM allows early intervention and more options for treatment. 相似文献

The double-deficit hypothesis of dyslexia posits that reading deficits are more severe in individuals with weaknesses in phonological awareness and rapid naming than in individuals with deficits in only one of these reading composite skills. In this study, the hypothesis was tested in an adult sample as a model of reading achievement. Participants were parents of children referred for evaluation of reading difficulties. Approximately half of all participants reported difficulty learning to read in childhood and a small subset demonstrated ongoing weaknesses in reading. Structural equation modeling results suggest that the double-deficit hypothesis is an accurate model for understanding adult reading achievement. Better reading achievement was associated with better phonological awareness and faster rapid automatized naming in adults. Posthoc analyses indicated that individuals with double deficits had significantly lower reading achievement than individuals with single deficits or no deficits. 相似文献

In a variety of fields, particularly human service occupations, the management of emotion is a precondition of employee and client well being. Based on qualitative data from participant observation and interviews, this study examines how firefighters are socialized to manage feelings and emotional displays. It concludes that firefighters recognized a need to manage their own emotions and those of their clients in order to deliver adequate service. Veteran firefighters facilitated the use of emotion labor techniques among newcomers by considering the emotion management knowledge and capabilities of job candidates during employee selection processes, providing habituated emotional events, and reinforcing customer service expectations. Newcomers actively participated in their own socialization to local emotion expectations through observational information seeking, retrospective surveillance, and performance of a normative newcomer role demeanor. The article concludes by offering practical and theoretical implications. 相似文献

Abstract ‘Internationalisation’ became a key theme in the 1990s both in higher education policy debates and in higher education research. Starting off from a heterogeneous set of phenomena, internationalisation does not merely mean varying border‐crossing activities on the rise anymore, but rather substantial changes: first, from a predominantly ‘vertical’ pattern of cooperation and mobility towards the dominance of international relationships on equal terms; second, from casuistic action towards systematic policies of internationalisation; third, from disconnection of specific international activities on the one hand and on the other internationalisation of the core activities towards an integrated internationalisation of higher education. Though higher education policy remains predominantly shaped on a national level and tends to underscore specific traditions and conditions of individual countries, the responsibility of individual institutions of higher education in Europe for their own future grows in the process internationalisation which is accompanied, among others, by growing pressure for diversity and increasing popularity of managenalism as well as by a policy of the European Commission which seems to favour de‐nationalisation of higher education. 相似文献

This article details a narrative inquiry journey between a novice pretenured professor and an experienced tenured professor from 2005 to 2009 to illustrate collaborative mentorship. The authors examine the importance of storied inquiry in studying mentoring and describe how their narrative journey as collaborators informed their relationship and respective understandings of the tenure process. Data were collected from written narratives, correspondence, and conversations within a mentorship program. Three dimensions of narrative inquiry are used to explore the themes of writing as nurturing the mentoring relationship and the assimilation into the academy: fear and anxiety along the tenureship path, building community and a collaborative mentorship, and balance between life and academia. 相似文献

During the past decade, there has been more than an adequate amount of research addressing issues regarding social studies methods courses. However, the apparent void is that there is no clear understanding of what pedagogical content knowledge or understanding of pedagogical approaches teacher candidates bring with them to social studies methods courses or what they expect from their time in social studies methods courses. The purpose of this study is to determine the mentality of the typical social studies methods course student, as he or she enters a social studies methods course. Employing analytic induction (Bogdan & Biklen, 2007; Erikson, 1986; Patton, 2002) and content analysis (Patton, 2002) to analyze and interpret the data, 9 categories for what the students know and 8 for what the students wanted to know were constructed. 相似文献

Currently, there are no Hebrew (L2) reading assessments that have been tested to obtain evidence for reliability and validity on which to base decisions about Hebrew instruction. The authors developed a Hebrew benchmark assessment tool for first grade students modeled after Dynamic Indicators of Basic Early Literacy Skills, a standardized test of accuracy and fluency used to identify at-risk students and to monitor student progress. Results of pilot data collection (N=53) provide evidence for strong alternate form reliability for this measure, as well as evidence for content, face and criterion-related validity. Future directions for research and development are discussed. 相似文献
