Abstract

In this paper, I present evidence for framing climate change education around social justice. More specifically, I provide empirical support for framing climate change education around intragenerational climate justice, and argue that this frame can influence youth in industrialized, wealthy nations to become mobilized, climate-engaged individuals. To do so, I apply critical qualitative analysis to narratives from American youth who participated in a global climate change education program in Bangladesh. My findings include the importance of contextualizing climate justice, framing climate change around humans, implicating ourselves in the problem and recognizing our own obligations in mitigation, seeing climate change as real and tangible, being in a place impacted by climate change, feeling solidarity with those impacted, and recognizing social injustice and power disparities within climate change impacts. Based on these findings, I recommend an approach that provides context, nuance, and personal connection to an otherwise abstract global problem.  相似文献

Athletes and their support team utilise technology to measure and evaluate technique and athletic performance. Existing techniques for motion and propulsion measurement and analysis include a combination of indirect methods (high-speed video) and direct methods (force plates and pressure systems). These methods are predominantly limited to controlled laboratory environments (in a small area relative to the competition environment), require expert advice and support, and can take significant time to evaluate the data. Consequently, the more advanced measurement techniques are considered to be restricted to specific coaching sessions, or periods in the year leading up to competition, when the time and expertise of further support staff are available. The more widely used, and simple, devices for monitoring ‘performance’ during running include stopwatches, GPS tracking and accelerometer-based systems to count strides. These provide useful information on running duration, distance and velocity but lack detailed information on many key aspects of running technique. In order to begin the process of development of more innovative technologies for routine use by athletes and coaches, a study was required to improve the understanding of athletes’ and coaches’ perception of their requirements from measurement technology. This study outlines a systematic approach to elicit and evaluate their perceptions, and presents the findings from interviews and a questionnaire. The qualitative data are presented as a hierarchical graphical plot (structured relationship model) showing six general dimensions (technique, footwear and surface, environment, performance, injury and cardiovascular) and shows the development of these general dimensions from the interviewee quotations. The questionnaire quantitative data enhances the study by further ranking characteristics that arise from the interviews. A contrast is shown between short and longer distance runner groups, as might be expected. The current technology available to elite runners is briefly reviewed in relation to the 22 characteristics identified as important to measure. The conclusions highlight the need for newer technologies to measure aspects of running style and performance in a portable and integrated manner, with suggestions as to size and weight likely to be acceptable to users for emerging devices.  相似文献

In this study, we examined the impact of a male opponent's pre-match body language and clothing (general vs. sports-specific) on how his performances were judged by an observer. Forty male tennis players viewed videos of a male target tennis player warming up and then observed playing footage of the target. Each participant viewed the target player warming up displaying one of four combinations of body language and clothing (positive body language/tennis-specific clothing; positive body language/general sportswear; negative body language/tennis-specific clothing; negative body language/general sportswear). Participants rated the performance of the tennis player and gave their perceptions of the likely outcome of a tennis match with the target player. Analyses of variance indicated that clothing and body language had an interactive effect on both outcome expectations and ratings of performance. The findings support the contention that the initial impressions athletes form of their opponents can influence the way in which they judge the performances of opponents and their perceived likelihood of success against the same opponents.  相似文献

This randomised controlled trial investigated changes in eccentric hamstring strength, 10m sprint speed, and change-of-direction (COD) performance immediately post Nordic hamstring curl (NHC) intervention and following a 3-week detraining period.

Fourteen male team sports athletes were randomised to a do-as-usual control group (CG; = 7) or to a NHC intervention group (NHC; = 7). Isokinetic dynamometry at 180°/s evaluated eccentric hamstring strength immediately post-intervention as the primary outcome measure. Secondary outcomes included 10 m sprint time and COD. Each outcome was measured, pre, immediately post-intervention and following a 3-week detraining period.

Immediately post-intervention significant group differences were observed in the NHC group for eccentric hamstring strength (31.81 Nm?1 vs. 6.44 Nm?1, P = 0.001), COD (?0.12 s vs. 0.20 s; P = 0.003) and sprint (- 0.06 s vs. 0.05 s; P = 0.024) performance. Performance improvements were maintained following a detraining period for COD (?0.11 s vs. 0.20 s; P = 0.014) and sprint (?0.05 s vs. 0.03 s, P = 0.031) but not eccentric hamstring strength (15.67 Nm?1 vs. 6.44 Nm?1, P = 0.145) These findings have important implications for training programmes designed to reduce hamstring injury incidence, whilst enhancing physical qualities critical to sport.  相似文献

ABSTRACT

Ankle injuries are highly prevalent in ballet, with strength highlighted as a primary risk factor. To profile ankle strength, fourteen female ballet dancers (age: 19.29 ± 1.59 years) completed an isokinetic testing protocol comprising concentric eversion (CONEV) and inversion (CONINV), and, eccentric inversion (ECCINV) trials at four angular velocities (30° · s?1, 60° · s?1, 90° · s?1, 120° · s?1) for both the dominant and non-dominant limb. In addition to Peak Torque (PT) and the corresponding Dynamic Control Ratios (DCRs), angle-specific derivatives of strength (AST) and Functional Range (FR) were calculated. There was no evidence of any significant bilateral strength asymmetry (p = 0.90) across all metrics, and no significant interactions with limb and contraction mode or velocity. A significant main effect for contraction mode (p = 0.001) highlighted greater ECCINV strength – which was maintained with increasing isokinetic velocity – in contrast to reductions in CONEV and CONINV strength. Specifically, dancers are ECCINV dominant at angular velocities greater than 60° · s?1, which is likely to be characteristic of most functional tasks. The lack of bilateral asymmetry may be attributed to dance training interventions that facilitate bilateral development, but ipsilateral mode and velocity-specific asymmetries have implications for injury risk and the training needs of female ballet dancers.  相似文献

The Permanent Subcommittee on Investigations of the U.S. Senate began a series of hearings in 1990 that uncovered an alarming pattern of waste, fraud, and abuse in the Title IV federal student aid programs. To create a stronger and more coordinated evaluation of institutions desiring to participate in these programs, Congress enacted the new Program Integrity Triad, which significantly increases the gatekeep‐ing functions of each member of the triad and establishes a specific set of responsibilities for accrediting agencies, the states, and the Secretary of Education. Under this program, states are directed to set up agencies known as State Postsecondary Review Entities (SPRE) to assist the U.S. Department of Education in reviewing institutions of higher education referred by the Secretary to determine continued participation in federal financial aid programs. The diverse ways in which students use community colleges will make it difficult, at best, to apply the quantifiable standards for withdrawal, graduation, and placement rates established by the SPRE program. The result could have serious implications for community colleges and their continued participation in Title IV federal student aid programs.  相似文献

There have been a number of articles recently advocating the use of nontraditional mediums to teach criminological theory. Many of these articles have advocated using music and/or music lyrics to illustrate and enliven the various theories taught in introductory theory courses. Despite the growing attention paid to teaching criminological theory, few, if any, discuss how to help students understand the more fundamental ontological question—what is “theory.” This article proposes an alternative pedagogical approach that draws upon students’ understanding of musical genres analogically to explain: (1) the historical development of the various theoretical approaches, (2) the historical, cultural and theoretical antecedents of the various approaches, and (3) how to identify the theoretical orientation(s) and influences in an unfamiliar text. Ultimately, this approach is intended to counter the overly compartmentalized and linear understanding of theory unintentionally brought on by the dynamics of teaching schedules, generic “theory” textbooks, computerized presentation software and testing methods.  相似文献

The primary objective of this study was to conduct a normative assessment of the research productivity and scholarly impact of tenured and tenure‐track faculty in school psychology programs accredited by the American Psychological Association (APA). Using the PsycINFO database, productivity and impact were examined for the field as a whole and by faculty rank and gender between 2005 and 2009. Results of our study reflected considerable variability in scholarly impact and productivity. For example, on average, school psychology faculty published slightly more than one refereed journal article per year, with productivity rates ranging from zero to eight articles per year. Similar variability in results was observed for scholarly impact. Results of this study also revealed no significant differences in productivity and impact by scholarly rank. Significant differences were observed for gender, however, with higher productivity and impact for men than women. A secondary objective of this study was to rank the most productive and impactful faculty by total authorship credit, number of publications, and number of citations, and to examine the relationships among these different rankings. Implications and limitations are discussed.  相似文献
