Clinging to dead ideas about teaching and learning limits our practice as professors. The resulting tyranny means we fail to educate our students as effectively as we might. This address challenges faculty to reconsider their understanding and habits in three areas: the preparedness of students, the impact of grading policies on learning motivation, and the role of technology in teaching. The good news is that learned behaviors, sociologically informed reflection, and the application of the research in the scholarship of teaching and learning can liberate us and improve the experiences of teachers and learners alike.  相似文献

Folk‐comedy duo, Flight of the Conchords, have become one of New Zealand's most successful musical exports, having attracted a large international audience through their American‐produced TV series. One of their central comic devices is to stylize well‐known singers and their music. This article focuses on how Flight of the Conchords shift their phonetic style towards that of various target personas, and how they maintain their own voices as comedians in the process. An acoustic analysis compares Flight of the Conchords’ pronunciation of four vowels (kit , dress , trap , and goat) to the pronunciation of the pop singers being stylized. Both Jemaine Clement and Bret McKenzie manipulate their vowel production towards that of the targeted personas. They also maintain some distance from their targeted roles through a range of devices including the use of exaggerated phonetic style. Through their performances, Flight of the Conchords recontextualize and parody a range of popular cultural products, continuing the enregisterment of certain phonetic styles with the voices of well‐known characterological figures.  相似文献

The recent and steady rise in the U.S. obesity index has resulted in a consumer-driven market for more effective treatment interventions for the morbidly obese population. Given the relatively poor outcomes associated with traditional approaches for treating obesity, such as diet programs, behavioral modification, and pharmacotherapy, weight loss surgical procedures represent a safe and effective option for those who meet selection criteria. To provide optimal treatment and consumer education, psychiatric nurses need to be well informed about the psychological and physiological aspects of these surgical procedures. This article clarifies six common misconceptions related to weight loss surgery.  相似文献

Where sociologists find resources, they infer power or status. However, sometimes resources are fleetingly held rather than enduringly controlled, and then status only translates into resources given impetus, or the motivation and momentary capacity to make resource claims. Status then rests on relations of impingement, whereby one actor gains resources and another loses them when the former’s impetus surges. These ideas are developed through an analysis of desk competition for front‐page space at The New York Times (1980–2005), where impetus is operationalized as the total number of newsworthy articles at each desk’s disposal on a given day. Statistical analysis reveals that all desks impinge and are impinged upon, though not equally, but also that a desk’s ability to impinge (efficacy) and susceptibility to impingement (vulnerability) are subject to change through time. This helps explain the most striking change in front‐page composition during this period: the sharp increase in national front‐page articles, and a corresponding decline in foreign front‐page articles, in the early 1990s.  相似文献

This article employs anti-essentialist Marxist analysis to shed light on the diverse economic activities that Filipina contract migrants are engaged in at home and overseas. We point to the limitations of dominant representations of these women as 'heroes' of national development or 'victims' of a global capitalist economy, which tend to foreclose a discussion of multiple class processes engendered by transnational labour migration. In drawing on a fluid theory of class, we investigate how contract domestic workers are involved in multiple class processes that allow them to produce, appropriate and distribute surplus labour in innovative ways. We also discuss the activities of the Asian Migrant Centre, a non-governmental organization working with domestic workers in Hong Kong, whose efforts to inspire the entrepreneurial aspirations of these women reflect the importance of recognizing migrant workers' multiple economic identities. This analysis has implications for how we imagine the agency of contract workers, as well as the performativity of research and advocacy work.  相似文献

Abstract

The study hypothesizes that the greater the satisfaction of a patient's basic motivational needs, the greater the likelihood that the patient will complete the program. Patients were given a self-report questionnaire to assess the strength of their basic motivational needs as they entered the program; and a Likert-type questionnaire concerning satisfaction of needs as they left the program. The results show that those who completed the program experienced greater satisfaction of needs than those who did not complete the program. Analysis of covariance of completion of the program and need satisfaction was significant (p < .01) thus supporting the hypothesis.

“Long-term Oral Contraceptive Use and the Risk of Breast Cancer,” THE CENTERS FOR DISEASE CONTROL CANCER AND STEROID HORMONE STUDY. Using oral contraceptives for long periods or using them when one has other risk factors has been hypothesized to increase the risk of breast cancer. To study these issues, we analyzed data from a multicenter, case-control investigation—the Centers for Disease Control's Cancer and Steroid Hormone Study. All women 20 to 54 years old with a first diagnosis of breast cancer ascertained by eight population-based cancer registries are study subjects; controls are selected at random from the general population of these eight areas. Analysis of the first 689 cases and 1,077 controls studied showed that women who had used oral contraceptives at some time in their lives had a relative risk of 0.9 compared with never-users (95% confidence interval, 0.8 to 1.2). Neither duration of oral contraceptive use nor time since first use altered a user's risk of breast cancer; women whose first use was more than 15 years ago and who used oral contraceptives for 11 years or more had a relative risk of 0.8 (0.5 to 1.4). Oral contraceptive use did not increase the risk of breast cancer among women with benign breast disease or a family history of breast cancer. Oral contraceptive use before a woman's first pregnancy did not increase her risk of breast cancer significantly more than other methods of delaying first pregnancy. This study provides no support to the hypothesis that oral contraceptive use increases a woman's risk of breast cancer. (Journal of the American Medical Association 1983;249:1591–1595.)

“Oral Contraceptive Use and the Risk of Ovarian Cancer,” THE CENTERS FOR DISEASE CONTROL CANCER AND STEROID HORMONE STUDY. Since oral contraceptives have been used by more than 40 million American women, an association between oral contraceptives and ovarian cancer could have a substantial public health impact. The Centers for Disease Control, Atlanta, is studying this relationship as part of a multicenter, case-control study—the Cancer and Steroid Hormone Study. During the first ten months of the study, we enrolled 179 women aged 20 to 54 years who had been ascertained to have newly diagnosed ovarian cancer by eight population-based cancer registries. From the general population of those eight areas, we selected as controls 1,642 women with intact ovaries. Users of oral contraceptives had an age-adjusted risk of ovarian cancer developing of 0.6 relative to those who had never used them (95% confidence interval, 0.4 to 0.9). The risk of ovarian cancer decreased with increasing duration of oral contraceptive use and remained low long after cessation of use. These results were not accounted for by parity, infertility, or other potentially confounding factors. We estimate that more than 1,700 cases of ovarian cancer are averted each year by past and current oral contraceptive use among women in the United States.

Abstract In this paper, we examine the demographic and socioeconomic characteristics of migration streams between metropolitan and nonmetropolitan areas for four different years over the period 1975–1993. During this period, there have been three shifts in the direction of net metro-nonmetro migration. Through nonmetro net in-migration, the “nonmetropolitan turnaround” of the 1970s reversed historical patterns of nonmetro loss of human resources, with gains and increased retention of the young and better-educated. The 1980s, however, again saw net-migration loss, including large shifts from gain to loss, especially among the young and better-educated and for workers in white collar occupations. In the 1990s, the overall pattern is again one of nonmetro net-migration gain or reduced loss, with the greatest increases among those higher status groups which experienced the greatest declines during the 1980s. The latest pattern is due largely to increased population retention, whereas previous research has shown the migration turnaround of the 1970s was due about equally to increasing retention and in-migration.  相似文献
