Sit–stand workstations offer a potential strategy to reduce prolonged occupational sitting. This controlled intervention study examined the effects of an environmental intervention on occupational sedentary time, musculoskeletal comfort and work ability, and the usability of sit–stand workstations in office work via a self-reported questionnaire. The intervention group (n?=?24) used sit–stand workstations during the 6-month intervention period, and the control group (n?=?21) used traditional sitting workstations. The results showed that working at sit–stand workstations can reduce sitting time significantly compared to control workstations (?6.7% vs. 5.0%, p?=?.019), which is reallocated mostly to standing (r?=??0.719, p?p?=?.028), as well as work ability (p?=?.022). The majority of intervention subjects rated sit–stand workstation adjustability as good (83.3%), and 75.0% were satisfied with the workstation. About 41.7% of the intervention participants, who were exclusively female, used the sit–stand function on a daily basis. While the environmental change alone was effective, it is likely that promoting the daily use of sit–stand workstations with counselling would lead to even more substantial positive effects.  相似文献   

Reassessing the People's Choice: Revisiting a Classic and Excavating Lessons for Research About Media and Voting     

Stephen Lacy  Michael Stamm 《Mass Communication and Society》2016,19(2):105-126

This article reassesses The People's Choice by Paul Lazarsfeld, Bernard Berelson, and Hazel Gaudet, one of the foundations of communication and voting behavior research. As with most classics, which are often cited but seldom read, we believe this book has much to teach contemporary social scientists. We return to the original context of the research and use voting data from the period with three broad goals: (a) to find ideas and lessons from this work that generally have been overlooked, (b) to suggest new ways of applying these ideas, and (c) to encourage scholars to engage more with this seminal work to understand ideas that are often overlooked when a complex piece of research is reduced to a brief discussion or passing citation.  相似文献   

Walter Lippmann’s Ghost: An Interview With Michael Schudson     

Michael Schudson 《Mass Communication and Society》2016,19(3):221-229

An esteemed scholar conducts an enlightening examination of the enduring issues of the press as a democratic institution, the professionalization of the journalist, journalism schools, liberalism, and science. This imagined one-on-one conversation with Walter Lippmann is lightly humorous yet offers important insights on the accountability of the government by the press in days gone by and on the accountability of the press to the public in our digital age.  相似文献

Academic socialization,parental educational expectations,and academic self‐efficacy among Latino adolescents     

Fernanda L. Cross  Aixa D. Marchand  Michael Medina  Andrea Villafuerte  Deborah Rivas‐Drake 《Psychology in the schools》2019,56(4):483-496

This study examined the direct association between parental educational expectations and adolescents’ academic self‐efficacy, as well as the moderating influence of parental academic socialization messages. Participants were 148 Latino parent–adolescent dyads with the majority of Mexican origin (80.4%). Most of the parent participants were mothers (85.8%). Adolescents were 13 (46%) or 14 (54%) years of age, and 53% identified as female. Adolescents reported their academic self‐efficacy and perceptions of their parents’ educational expectations; parents reported on their academic socialization messages of shame/pressure and effort regarding academics. The results suggest that, after accounting for parents’ level of education and immigrant status, parental educational expectations were positively associated with adolescent academic self‐efficacy. This association was stronger among adolescents whose parents reported transmitting fewer messages of shame/pressure and academic effort. These results point to the importance of nuances in the content and type of academic socialization messages within Latino families.  相似文献   

Modelling quality     

Michael Christie  Hetty Grunefeld  Gerda Thibautt 《European Journal of Engineering Education》2001,26(4):441-450

This article argues that the increase in the number of teaching and learning centres in universities of technology in recent years is bound up with concerns about the quality of university education. Universities that have set up such centres have been motivated to do so for two main reasons. They are keen to improve the image and the capacity of their teaching faculty. They also hope to attract students at a time when many school leavers prefer immediate, well-paid employment to four or more years of study. There has been outside pressure as well. Governments have demanded that tertiary institutions become more accountable. Governments are insisting that taxpayers get value for their money, especially in the area of teaching and learning. The question asked in this article is whether or not teaching and learning centres should be modelling quality issues as well as teaching and learning issues. Our conclusion is that the centres should be proactive in this matter, providing their institution with both theoretical and practical models of quality management and assurance.  相似文献   

The development of the ability to recognize the meaning of iconic signs     

Tolar TD  Lederberg AR  Gokhale S  Tomasello M 《Journal of deaf studies and deaf education》2008,13(2):225-240

Early developmental psychologists viewed iconic representation as cognitively less complex than other forms of symbolic thought. It is therefore surprising that iconic signs are not acquired more easily than arbitrary signs by young language learners. One explanation is that children younger than 3 years have difficulty interpreting iconicity. The current study assessed hearing children's ability to interpret the meaning of iconic signs. Sixty-six 2.5- to 5-year-olds who had no previous exposure to signs were required to match iconic signs to pictures of referents. Whereas few of the 2.5-year-olds recognized the meaning of the iconic signs consistently, more than half of the 3.0-year-olds and most of 3.5-year-olds performed above chance. Thus, the ability to recognize the meaning of iconic signs gradually develops during the preschool years. Implications of these findings for sign language development, receptive signed vocabulary tests, and the development of the ability to interpret iconic symbols are discussed.  相似文献   

Student drug use in Bermuda     

Michael West 《European Journal of Psychology of Education - EJPE》1987,2(4):327-336

Student drug use has been investigated in many countries and a standard method of conducting such surveys is described here. Using an adapted World Health Organization questionnaire patterns of drug use were investigated among the population of secondary school students in Bermuda (N=3,930). The prevalence of use of alcohol and eight illicit drugs is described and related to students’ attitudes, life-styles and demographic characteristics. Factors such as age, sex, race, parental use of alcohol, leisure time activities, allowances and beliefs about drugs all emerge (as they have in other studies) as strongly related to drug use. It is concluded that though these cross cultural similarities exist, there are important sub-cultural differences in drug use patterns which reflect social dynamics and characteristics within communities. It is suggested that a focus on sub-cultural differences may be particularly valuable in future research.  相似文献
