Human generated environmental problems are significant issues of global concern. Despite this, varying attitudes towards environments continue to exist across the globe, impacting on environmental decision-making and action at local, national and international levels. This paper probes some of the similarities and differences in environmental attitudes amongst pre-service teachers in Australia, Republic of Maldives and Indonesia. Data were collected using an established environmental attitude questionnaire and individual interviews. The three communities exhibited a similar range of environmental attitudes using the established questionnaire but significant differences emerged when the interview data were analysed phenomenographically. These differences reflect diversity within and across cultural groups that cannot be satisfactorily explained by the theory underpinning the established questionnaire. Consequently, a revised conceptual framework is proposed.  相似文献

We present an overview of previous research results on the molecular phylogenetic analyses in Agaricales and its higher ranks (Agaricomycetes/Agaricomycotina/Basidiomycota) along with the most recent treatments of taxonomic systems in these taxa. Establishing phylogenetic hypotheses using DNA sequences, from which an understanding of the natural evolutionary relationships amongst clades may be derived, requires a robust dataset. It has been recognized that single-gene phylogenies may not truly represent organismal phylogenies, but the concordant phylogenetic genealogies from multiple-gene datasets can resolve this problem. The genes commonly used in mushroom phylogenetic research are summarized.  相似文献

Social networking sites are considered a valuable resource to maintain existing friendships even over considerable distances. The present study emphasizes tie strength as a crucial determinant for the use of interactive and passive features among 302 active Facebook users and friends of different relational closeness (close friends vs. casual friends vs. acquaintances) as well as a moderator for the impact of physical distance. As expected, tie strength affected direct interaction linearly, whereas social surveillance followed a quadratic trend. Furthermore, moderation analyses revealed less frequent direct interaction between close friends and stronger surveillance of casual friends’ profiles as physical distance increases. These results indicate different functions in relationship maintenance for both behaviors as direct interaction aims at nurturing current relationships, while surveillance serves as a catalyst for promising future communications. As a consequence, physical distance influences direct interaction adversely due to emerging constraints but also contains informational value encouraging information-seeking behaviors.  相似文献

Tracing one's family genealogy is a complex process that requires situating a family's narratives within a historical context. This article reviews the use of critical family history research in an undergraduate Asian American studies course to examine not only the diversity and experiences of Asian Americans but also the unspoken narratives that lead to the creation of a single story. We are told single stories that often neglect the sociocultural factors—the historical reality—of our past. Our family histories are constructed historically and are embedded in social, political, and economic processes and relationships. This article argues that we need to complicate what we know about our past and examine policies and cultural practices that lead to a racialized system of power and privilege, racialized policies, and racialized oppression and progression.  相似文献

The month of February 2015 marked the fiftieth anniversary of the foundation of the Sports Council. Despite its central role in sports governance in Britain, the advisory Council of 1965 and its successor bodies have received little attention from historians. This article assesses the early history of the Sports Council, using primary material such as National Archive papers and memoirs by practitioners to focus attention particularly on the period of Margaret Thatcher’s premiership in the 1980s. The pre-1979 Council commanded widespread respect, and the article explores how and why it became beleaguered thereafter, attributing this to a combination of ideological distrust as ‘Thatcherism’ gained in strength, shortcomings on the part of the Council itself and parochial in-fighting among leading sports bodies. By the mid-1980s the Council was under scrutiny as never before, some in the political and sporting world questioning whether it had a viable future. Although it survived to fight another day, the confidence and momentum of earlier years became a thing of the past and the way was opened up for a major overhaul of sports administration to be carried out in the 1990s.  相似文献

In recent years, web sites where individual consumers can rate and review goods and services have mushroomed all over the Internet. Restaurants are particularly affected by online reviewing. If the impact of online consumer reviews (OCRs) on the demand side of markets is now well understood and measured, few studies examine the reception of this new evaluation method by those who are assessed. Based on interviews with French restaurant managers, our research shows that OCRs systems reconfigure relations of accountability in the restaurant industry. We use the notion of reactivity to describe the mechanisms through which the new evaluation system transforms the activity of restaurants. We also examine the affects surrounding the reception of ratings and reviews by restaurant managers and the moral criteria that accompany their discourses on online reviews. Many restaurants consider online reviews as a brutal and hypocritical mode of judgment. The judgment produced by online ratings and reviews is not easily borne by restaurant managers, because it challenges the conventions of quality they had previously internalized as legitimate, that is, those produced by professional experts. We interpret this ambivalent reception as the unfinished movement of transforming a performative reputation device into a legitimate evaluation institution.  相似文献

Limb dominance theory suggests that females tend to be more one-leg dominant and exhibit greater kinematic and kinetic leg asymmetries than their male counterparts, contributing to the increased risk of anterior cruciate ligament injury among female athletes. Thus, the purpose of this study was to examine the influences of sex and limb dominance on lower extremity joint mechanics during unilateral land-and-cut manoeuvres. Twenty-one women and 21 men completed land-and-cut manoeuvres on their dominant limb as well as their nondominant limb. Three-dimensional kinematics and kinetics were calculated bilaterally for the entire stance phase of the manoeuvre. Women performed land-and-cut manoeuvres with altered hip motions and loads as well as greater knee abduction at touchdown compared to men. Dominant limb land-and-cut manoeuvres where characterised by decreased hip flexion at touchdown as well as decreased hip flexion and adduction range of motion compared to nondominant land-and-cuts regardless of sex. The observed sex differences are consistent with previous research regarding mechanisms underlying the sex disparity in anterior cruciate ligament injury rates. However, observed differences regarding limb dominances appear somewhat arbitrary and did not suggest that the dominant or nondominant limb would be at increased risk of anterior cruciate ligament injury.  相似文献

Purpose: Scholarship is essential for the growth and development of the physical education field. Over time, scholarship expectations have changed, forcing faculty members to alter time spent for research, teaching, and service. Social-cognitive career theory (SCCT) presents a model for understanding performance and persistence in an occupational environment. The interconnected aspects of SCCT have different emphasis related to self-efficacy, outcome expectations, or personal goals pursuit. This study explored physical education teacher education (PETE) faculty members’ continuing engagement in scholarly activity through SCCT. Method: Data collection included interviews with 9 senior PETE faculty members who met the criteria for “productive scholars over time.” Curriculum vitae were collected to verify productivity. Results: Data analysis revealed guidepost themes that included collaborating, finding balance, defining a research process, and maintaining a strong work ethic. Roadblocks encountered included other obligations and lack of support for research. Conclusions: Participants demonstrated strong self-efficacy; held high, positive expectations for success; and set very specific, clear, and deliberate goals. Participant behavior was moderated by their personal attributes (capacity to build relationships, set goals, and maintain interest and passion) and was tempered by the environments in which they worked. Fostering similar behaviors has the potential to guide future and current PETE faculty members in creating supportive and encouraging atmospheres for sustained productivity. The lack of literature relating to this topic warrants the need for more research exploring the influential factors and benefits gained from sustained scholarly productivity over time for PETE faculty members.  相似文献

Prior research indicates that providing participants with positive augmented feedback tends to enhance motor learning and performance, whereas the opposite occurs with negative feedback. However, the majority of studies were conducted with untrained participants performing unfamiliar motor tasks and so it remains unclear if elite athletes completing familiar tasks respond in a similar fashion. Thus, this study investigated the effects of three different versions of false-performance feedback on punching force (N), pacing (force over time) and ratings of perceived exertion (RPE) in 15 elite amateur male boxers. Athletes completed a simulated boxing bout consisting of three rounds with 84 maximal effort punches delivered to a punching integrator on four separate days. Day one was a familiarisation session in which no feedback was provided. In the following three days athletes randomly received false-positive, false-negative and false-neutral feedback on their punching performance between each round. No statistical or meaningful differences were observed in punching forces, pacing or RPE between conditions (> 0.05; ≤ 2%). These null results could stem from the elite status of the athletes involved, the focus on performance rather than learning, or they may indicate that false feedback has a less potent effect on performance than previously thought.  相似文献
