Commercially available compression garments or electrical stimulation do not enhance recovery following a sprint competition in elite cross-country skiers

This study investigated whether commercially available compression garments (COMP) exerting a moderate level of pressure and/or neuromuscular electrical stimulation (NMES) accelerate recovery following a cross-country sprint skiing competition compared with a control group (CON) consisting of active recovery only. Twenty-one senior (12 males, 9 females) and 11 junior (6 males, 5 females) Swedish national team skiers performed an outdoor sprint skiing competition involving four sprints lasting ～3–4 min. Before the competition, skiers were matched by sex and skiing level (senior versus junior) and randomly assigned to COMP (n?=?11), NMES (n?=?11) or CON (n?=?10). Creatine kinase (CK), urea, countermovement jump (CMJ) height, and perceived muscle pain were measured before and 8, 20, 44 and 68?h after competition. Neither COMP nor NMES promoted the recovery of blood biomarkers, CMJ or perceived pain post-competition compared with CON (all P?>?.05). When grouping all 32 participants, urea and perceived muscle pain increased from baseline, peaking at 8?h (standardised mean difference (SMD), [95% confidence intervals (CIs)]): 2.8 [2.3, 3.2]) and 44?h (odds ratio [95% CI]: 3.3 [2.1, 5.1]) post-competition, respectively. Additionally, CMJ was lower than baseline 44 and 68?h post-competition in both males and females (P?相似文献   

How responsive is E-Government? Evidence from Australia and New Zealand

Governments around the world are increasingly moving toward online service delivery in what is commonly called e-government. There are high hopes for e-government, particularly that the associated technologies provide the scope to make government services more responsive. This article reports on a 2006 study of one aspect of e-government responsiveness, namely, the basic capacity to answer a simple question posted by email. To this end, federal and state agencies in Australia, and central and local government agencies in New Zealand were emailed (n = 273). Data related to locating contact email addresses and subsequent responses was collected. The key finding was that the Australian agencies consistently did not perform as well as their New Zealand counterparts, bringing into question one component of their higher ranking in international e-government studies and also their potential to deliver on the Australian government policy that e-government means more responsive government.     

Utilizing Science Philosophy Statements to Facilitate K-3 Teacher Candidates’ Development of Inquiry-based Science Practice

This study utilized pre-service teachers’ philosophy statements to connect their beliefs for science teaching with inquiry-based constructivist classroom practice. The major findings of this study suggested that before entering the classroom prospective teachers are strongly aligned with inquiry-based, constructivist-based theories, and describe teaching science as a process approach. However, after entering public classrooms the teacher candidates often abandoned those notions of constructivist, inquiry-based science in favor of a more traditional approach to science instruction. This study addresses a method to engage prospective teachers in designing inquiry-based science pedagogy as well as developing their professional pedagogical confidence.     

Students as co-producers in a multidisciplinary software engineering project: addressing cultural distance and cross-cohort handover

This article reports an undergraduate software engineering project in which, over a period of 2 years, four student teams from different cohorts developed a note-taking app for four academic clients at the students’ own university. We investigated how projects involving internal clients can give students the benefits of engaging in real software development while also giving them experience of a student-staff collaboration that has its own benefits for students, academics, and the university more broadly. As the university involved is a Sino-Foreign university located in China, where most students are Chinese and most teaching staff are not, this ‘student as co-producer’ approach interacts with another feature of the project: cultural distance. Based on analysis of notes, reports, interviews, and focus groups, we recommend that students should be provided with communicative strategies for dealing with academics as clients; universities should develop policies on ownership of student-staff collaborations; and projects should include a formalised handover process. This article can serve as guidance for educators considering a ‘students as co-producers’ approach for software development projects.     

Recovering Predictor–Criterion Relations Using Covariate-Informed Factor Score Estimates

Although it is currently best practice to directly model latent factors whenever feasible, there remain many situations in which this approach is not tractable. Recent advances in covariate-informed factor score estimation can be used to provide manifest scores that are used in second-stage analysis, but these are currently understudied. Here we extend our prior work on factor score recovery to examine the use of factor score estimates as predictors both in the presence and absence of the same covariates that were used in score estimation. Results show that whereas the relation between the factor score estimates and the criterion are typically well recovered, substantial bias and increased variability is evident in the covariate effects themselves. Importantly, using covariate-informed factor score estimates substantially, and often wholly, mitigates these biases. We conclude with implications for future research and recommendations for the use of factor score estimates in practice.     

Expert Perspectives on the Future of Physical Education in Higher Education

Despite physical education teacher education/physical education sport pedagogy’s (PETE/PESP’s) significant strides in the past century, there are concerns about its future. Grounded in participatory research, and through an interview-Delphi method, this study purposefully sampled five male PETE/PESP scholars’ expert critiques of current threats, projections of probable and preferable futures, and recommendations for transformation. Data were analyzed through an interpretive approach. Findings included: (a) limitations in physical education policy, teacher preparation, and status as key threats; (b) more of the same conflicts in the probable future and increased cooperation regarding conflicts in the preferable future; and (c) proactively revising the subdisciplinary framework and doctoral studies as transformative recommendations. We interpret issues critiqued as threatening PETE/PESP’s future, and projections of the probable future, as reflective of neoliberal rationality that has renormalized academic work in de-democratizing ways. We interpret that projections of preferable futures and transformative recommendations call for a re-emphasis on ethical academic attitudes to resist neoliberalization and reclaim democracy.
