Managing Masculinities: The Metrosexual Moment     

Helene Shugart 《传播与批判/文化研究》2013,10(3):280-300

In this essay, I explore the historical moment of metrosexuality in popular culture that, I argue, rather than simply a fad, constituted a logical premise vital to assuaging the “crisis” in masculinity engendered by the phenomenon of commercial masculinity. I trace the ways in which the fleeting trend of metrosexuality was articulated rhetorically in US popular culture in such a way as to rationalise commercial masculinity in targeted, explicit ways. I argue that metrosexuality served a crucial rhetorical function for the reconciliation of commercial masculinity with normative masculinity by organising homosociality in strategic ways. Accordingly, I suggest that apparently transient popular cultural trends might best be understood in terms of their location in—and strategic rhetorical function for—broader cultural discourses.  相似文献   

Reinventing Privilege: The New (Gay) Man in Contemporary Popular Media     

Helene A. Shugart 《Critical Studies in Media Communication》2013,30(1):67-91

In recent years, the gay man/heterosexual woman couple configuration has become a genre unto itself in mediated popular culture, resulting in unprecedented mainstream visibility for gay men. Major mainstream films, such as My Best Friend's Wedding, Object of My Affection, and The Next Best Thing, showcase this combination as their centerpiece, as does the highly rated prime-time network situation comedy, Will & Grace. In this essay, I assess this particular performance of gay identity in order to discern what qualities render it – as presented in this configuration – not only acceptable but popular, given the heteronormative sensibilities that characterize the mainstream audience to which it is directed. I argue that, in these texts, homosexuality is not only recoded and normalized in these representations as consistent with privileged male heterosexuality but is articulated as extending heterosexual male privilege. In so doing, blatant sexism is reinvented and legitimized, and gay male identity simultaneously is defined by and renormalizes heteronormativity.  相似文献   

Congruence of student teachers' pedagogical images and actual classroom practices     

Lena Fung  Lina P.Y. Chow 《Educational research; a review for teachers and all concerned with progress in education》2013,55(3):313-321

An understanding of student teachers' pedagogical images plays an important role in helping teacher educators plan learning experiences. The purposes of this study were to obtain a profile of pedagogical images of a group of student teachers, and to assess whether there is congruence between their pedagogical images and classroom practices. Applying the conception of teaching model proposed by Pratt, Chan developed a questionnaire to evaluate teachers' views about teaching, which was modified here and administered to 59 first-year student teachers before and after their teaching practicum in physical education for secondary schools. Results indicated that the student teachers possess a Nurturing image, whereas in actual classroom practices, their approach was a mix between the Apprenticeship and the Transmission approaches. In other words, whereas student teachers conceive themselves as having a more child-centred approach to teaching, in reality, their practices constituted more a teacher-centred approach. The investigators considered that this type of information would be helpful for teacher educators when planning learning experiences.  相似文献   

A Comparative Study of Primary and Secondary School Students' Images of Scientists     

Yvonne Y. H. Fung 《Research in Science & Technological Education》2013,31(2):199-213

The Draw-A-Scientist Test was administered to 675 Hong Kong Chinese students to explore their images of scientists. The main purposes were to discover any differences across grade levels and between male and female students, and to see if the results were comparable to those found in studies in other parts of the world. As in the findings of earlier research, there was evidence that students developed a more stereotypic image of a scientist with age and that the scientists drawn were predominantly male. It was also noted that some students, though a small percentage, included special captions and comments to express their views of the scientist. While the DAST is a feasible and simple method, future studies should supplement it with interviews for deeper understanding of students' constructs.  相似文献   

Teachers' views on and use of printed materials in a distance learning teacher education course     

Yvonne Y. H. Fung 《Open Learning》2013,28(2):175-183

Despite the heavy emphasis on online learning in recent years, print is still an important medium for course delivery in distance education. Distance educators have argued that, with the incorporation of appropriate access structures, distance learning materials can be self‐instructional and interactive. This study aims to explore the extent to which students on a distance teacher education course considered that the print materials had achieved the course objectives, and how they made use of the in‐text access structures. The results indicate that, although teachers on the course agreed that the materials were able to achieve the course objectives, the extent to which they made use of the access devices varied considerably.  相似文献   

Face-to-Face Tutorials in a Distance Learning System: Meeting student needs   总被引：2，自引：2，他引：0  

Yvonne Fung  Ronnie Carr 《Open Learning》2013,28(1):35-46

Many distance learning programmes include an element of face-to-face tuition. This paper reports on a research project concerned with various issues related to face-to-face tutorials in the Open University of Hong Kong's distance education system, including students' expectations of the benefits they will gain; their reasons for attending; the approaches they prefer; and their overall satisfaction with what tutors actually provide. Some comparisons are drawn between students in the university's different schools-and the overall findings are compared with those reported for distance learners in the West, in an effort to assess the impact of cultural context on student attitudes to tutorials. The research found that the Hong Kong students' attendance at tutorials was very high compared to that found in other similar studies, possibly reflecting Hong Kong's geographical compactness, but also possibly reflecting a preference for face-to-face meetings; that the students looked for specific guidance and support from tutors within a largely directive framework; that even where the format of the tutorial departed from the students' expectations, the students did not necessarily give the tutorial a low evaluation, provided that it was a fruitful experience; and that the cultural context within which a distance education system operates affects students' expectations and learning styles.  相似文献   

Conceptions of learning and quality of university life among deaf,hard of hearing,and hearing university students     

Sanyin Cheng  Kuen Fung Sin 《International Journal of Inclusive Education》2013,17(12):1333-1344

ABSTRACT

This study explores how conceptions of learning relate to quality of university life among deaf or hard-of-hearing (DHH) and hearing university students in mainland China. The Conceptions of Learning Inventory III and the Quality of University Life Measure were administered to 200 DHH and 240 hearing students. Results showed that deep-level conceptions of learning (learning as duty) significantly and positively predicted quality of university life among DHH and hearing students, while surface-level conceptions of learning (learning as gaining information) significantly negatively predicted quality of university life among DHH students. The significance, limitations, and implications of the present research for university administrators, teachers, and students are discussed.  相似文献   

Public apprehension of emerging infectious diseases: are changes afoot?     

Joffe H 《Public understanding of science (Bristol, England)》2011,20(4):446-460

Using social representations theory this paper casts light on the pattern of content that characterises the public response to emerging and re-emerging infectious diseases (EID). The pattern is: distancing the disease from the self/ one's in-groups; blame of particular entities for the disease's origin and/or spread; and stigmatisation of those who have contracted it and/or who are represented as having intensified its spread. This pattern is not unique to EID but extends to many risks, making EID fruitful events for understanding public apprehension of potential dangers. This process may be driven by worry, fear and anxiety since when levels of these are low, as has arguably been the case with the 2009/10 "Swine Flu" pandemic, the pattern transforms. The distancing-blame-stigma pattern may also be transformed by growing reflexivity, a feature of late modern societies, as well as material features of the epidemic and "EID fatigue".  相似文献   

Microfluidic device for generating a stepwise concentration gradient on a microwell slide for cell analysis     

Emilie Weibull  Shunsuke Matsui  Manabu Sakai  Helene Andersson Svahn  Toshiro Ohashi 《Biomicrofluidics》2013,7(6)

Understanding biomolecular gradients and their role in biological processes is essential for fully comprehending the underlying mechanisms of cells in living tissue. Conventional in vitro gradient-generating methods are unpredictable and difficult to characterize, owing to temporal and spatial fluctuations. The field of microfluidics enables complex user-defined gradients to be generated based on a detailed understanding of fluidic behavior at the μm-scale. By using microfluidic gradients created by flow, it is possible to develop rapid and dynamic stepwise concentration gradients. However, cells exposed to stepwise gradients can be perturbed by signals from neighboring cells exposed to another concentration. Hence, there is a need for a device that generates a stepwise gradient at discrete and isolated locations. Here, we present a microfluidic device for generating a stepwise concentration gradient, which utilizes a microwell slide''s pre-defined compartmentalized structure to physically separate different reagent concentrations. The gradient was generated due to flow resistance in the microchannel configuration of the device, which was designed using hydraulic analogy and theoretically verified by computational fluidic dynamics simulations. The device had two reagent channels and two dilutant channels, leading to eight chambers, each containing 4 microwells. A dose-dependency assay was performed using bovine aortic endothelial cells treated with saponin. High reproducibility between experiments was confirmed by evaluating the number of living cells in a live-dead assay. Our device generates a fully mixed fluid profile using a simple microchannel configuration and could be used in various gradient studies, e.g., screening for cytostatics or antibiotics.  相似文献
