This review presents a conceptual framework and supporting evidence that links impaired motor control after sport-related concussion (SRC) to increased risk for musculoskeletal injury. Multiple studies have found that athletes who are post-SRC have higher risk for musculoskeletal injury compared to their counterparts. A small body of research suggests that impairments in motor control are associated with musculoskeletal injury risk. Motor control involves the perception and processing of sensory information and subsequent coordination of motor output within the central nervous system to perform a motor task. Motor control is inclusive of motor planning and motor learning. If sensory information is not accurately perceived or there is interference with sensory information processing and cognition, motor function will be altered, and an athlete may become vulnerable to injury during sport participation. Athletes with SRC show neuroanatomic and neurophysiological changes relevant to motor control even after meeting return to sport criteria, including a normal neurological examination, resolution of symptoms, and return to baseline function on traditional concussion testing. In conjunction, altered motor function is demonstrated after SRC in muscle activation and force production, movement patterns, balance/postural stability, and motor task performance, especially performance of a motor task paired with a cognitive task (i.e., dual-task condition). The clinical implications of this conceptual framework include a need to intentionally address motor control impairments after SRC to mitigate musculoskeletal injury risk and to monitor motor control as the athlete progresses through the return to sport continuum. 相似文献

Education Preparation Programs (EPPs) are increasingly pressured to demonstrate alignment between program supports and candidates’ outcomes. Using mixed methods, we studied the Early Field Immersion School (EFIS), an effort to improve candidates’ early field experiences. Participants included 171 candidates enrolled in a graduate certificate program and 11 university-based faculty. EFIS candidates spent increased time in early field experiences, yet EFIS was not associated with candidates’ performance at program exit. Although we found that while candidates and faculty alike valued EFIS supports, participation was negatively associated with perceptions of preparedness. We discuss these discrepancies and offer suggestions for ongoing research. 相似文献

Building upon prior research documenting differential effects of psychological maltreatment, physical, and sexual abuse on youth mental health outcomes (Spinazzola et al., 2014), the present study sought to clarify the relative predictive contributions of type of maltreatment compared to salient exposure characteristics. The sample included 5058 clinic-referred youth from the Core Dataset (CDS) of the National Child Traumatic Stress Network (NCTSN) with lifetime histories of exposure to one or more of three specific types of maltreatment: psychological maltreatment (PM), physical abuse (PA), and sexual abuse (SA). First, we examined variations in salient trauma characteristics (age of onset, duration of exposure, number of co-occurring trauma types, and perpetrator type and number) by maltreatment group. Second, we examined whether type of maltreatment remained associated with mental health measures after adjusting for demographic variables and trauma characteristics. Profiles for youth with PM were more severe than youth who experienced either PA or SA only. Co-occurring PM and PA was associated with the most severe trauma exposure profile and with severity of PTSD symptoms, even after adjusting for demographic and trauma characteristics. Youth exposed to SA only had a distinct trauma profile and greater PTSD symptom severity after adjusting for demographic and trauma characteristic variables. Study findings hold important implications for trauma screening, assessment, and intervention, as well as for traumatic stress research methods that extend beyond abuse-specific or cumulative-risk approaches. 相似文献

Although video clubs have been used to support (student) teachers' learning through reflection upon practice, less attention has been paid to their potential use for supporting changes in participants' practice over a period of time. Prior work has also largely treated (student) teachers as an undifferentiated whole that benefits in similar ways from video clubs. In this study, we problematize this assumption by drawing on three cases of student teachers to exemplify three different learning paths while participating in a video club during field placement. Reflecting on these findings, we discuss implications for differentiating the video-club approach to address different student teachers. 相似文献

The association between child maltreatment (CM) and educational outcomes have been well documented. However, there is a paucity of research that explores the association between different types of maltreatment and other school problems that may affect the educational outcomes of maltreated children. This study examined the association between different types of CM and school changes, concentration problems, and special educational needs. Gender differences were also examined. Structured interviews were conducted with 2,980 participants. Significant associations emerged between CM, in particular, multiple maltreatment experiences and school problems. Males had higher concentration difficulties and special educational needs. More research attention is needed into optimal learning environments and interventions that support maltreated children more effectively. 相似文献

ABSTRACT Many museums are housed in historic buildings, sometimes the building itself is part of the museum collection. Creating a stable environment by providing a nearly constant temperature and relative humidity at correct levels decreases the risk of object degradation. Maintaining this steady indoor environment, however, increases energy consumption and risks to the historic building. Museum display cases offer a solution to the mitigation of risks to which valuable objects may be subjected by providing an extra layer of protection to indoor climate fluctuations. The Anne Frank House is a historic house museum located in Amsterdam. The museum has undergone several renovations in the last years to deal with an increase in the number of visitors to over 1.2 million a year. The original diaries and other documents of Anne Frank are permanently on display in the Anne Frank House. With the recent refurbishment the possibility arose to design a new state-of-the-art display case. This study presents the results of the experimental research related to the design, performed in-situ. The temperature and relative humidity in the new exhibition space and inside the new display cases were monitored to gain insight into the hygrothermal behavior of these controlled environments. A complementary numerical study was performed to investigate effects of dynamic climate control of the exhibition gallery and climate conditions in the display case under various circumstances. Four main conclusions are presented in this paper. The investigated display case design is able to provide a stable relative humidity environment by means of silica gel, while using an active box-in-box climate control system to create stable temperature conditions. The inner case temperature depends on the temperature supplied by the display case air handling unit. Protocols must be in place in case of malfunction or failure of the climate control system of the display case. The air handling unit of the case needs to be shut off to create a passive environment for the objects on display until necessary actions are taken. Exhibition gallery set points can be less stringent when susceptible museum objects are on display in the display case. The environments are separated and provide an opportunity for energy saving set point strategies. The last conclusion drawn is that the numerical study provides valuable insight into imposing dynamic control of set points for temperature and relative humidity in the exhibition gallery and the effect on the display case environment. 相似文献

ABSTRACTThis study operationalized Weick’s [(1988). Enacted sensemaking in crisis situations. Journal of Management Studies 25(4), 305–317 and (1993). The collapse of sensemaking in organizations: The Mann Gulch disaster. Administrative Science Quarterly, 38, 628–652] theory of enacted sensemaking to examine the communication processes associated with the Flint Water Crisis of 2014–2015. A content analysis of 389 emails and attachments from a total population of N?=?37,376 pages of publicly released e-mails and documents pertaining to Flint’s water issues, identified examples of failed sensemaking by government officials. These failures hastened and intensified a growing crisis of lead contamination and an outbreak of Legionnaires disease associated with Flint’s municipal water system. Analysis of email messages suggests that strong commitments by top leaders and limited capacity were important factors as were efforts to create and maintain consensus among officials. The Flint Water Crisis offers an important application of sensemaking theory and its utility for both organizational and risk communication scholars and for practical application. The authors emphasize the importance of questioning previous assumptions and commitments, insuring that communication practitioners are involved in decisions, and avoiding over reliance on image repair as a strategic response. 相似文献

AbstractThis study examined a project that delivered social work services to homeless individuals. A mixed-methods case study was conducted using quantitative and qualitative data from 93 library employees and the project’s Homelessness Prevention Outreach Worker (HPOW). There was an increase in the number of clients accessing community supports during the project, and the HPOW was integral to the provision of support and resources to homeless individuals. Staff training was associated with significantly greater knowledge, comfort, and skills in working with homeless individuals. These findings can inform the delivery and implementation of similar programs for homeless individuals. 相似文献
