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

Characteristics of early adopters of end-user online searching in the health professions 总被引:1,自引:0,他引:1
J G Marshall 《Bulletin of the Medical Library Association》1989,77(1):48-55
This paper examines end-user, online searching using data from a questionnaire mailed to 150 Canadian health professionals in practice settings. The response rate was 83% (n = 124). The data provide a demographic profile of early adopters of end-user searching in the health care community. Positive correlations with the user's level of implementation of end-user searching were found for the following variables: amount of time spent in research activities, amount of system training received, and use of Medical Subject Headings (MeSH). There was a negative association between the amount of time spent in patient care and implementation level. General practitioners and family physicians had lower implementation levels than physicians in other specialties. Successful implementers were more likely to be computer literate and to place a high value on formal information sources such as books, journals, and libraries. Health professionals using so-called "user-friendly" or menu-based software had lower levels of personal commitment to using online databases, as measured by a combination of continuance of use, willingness to pay personally, type of recommendations made to colleagues, and hardware ownership. 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
