The incidence and wage effects of overeducation     

Greg J. Duncan  Saul D. Hoffman 《Economics of Education Review》1981,1(1):75-86

Data gathered from a recent national sample of workers on educational requirements and attainments are used to examine the extent and economic effects of overeducation. Nearly 40 percent of the U.S. work force-and about 50 percent of black males-have more education than their jobs require. But we also find that “surplus” education does have economic value. The individual return to an additional year of surplus education was positive and significant for all major demographic groups. The estimated return is, however, only about half the size of the return to an additional year of required education.  相似文献   

The effects of changing pace on metabolism and stroke characteristics during high-speed breaststroke swimming   总被引：1，自引：0，他引：1

Performances often vary between the heats and finals of breaststroke swimming competitions possibly because the swimmers try to conserve their energy, or for other tactical reasons. Additionally, coaches might advise either a 'positive' or 'even' pace race strategy during the final. The effect of such pacing changes on metabolism (blood lactate, heart rate, ventilation), ratings of perceived exertion, stroke kinematics and turning times have not been investigated. Nine male competitive breaststroke swimmers swam three paced (Aquapacer) 200-m trials, 48 h apart and in random order, at 98%, 100% and at an attempted 102% of their maximal 200-m time-trial speed. Responses in metabolic variables were similar between the 98% and 100% trials, but higher post-exercise blood lactate concentrations and respiratory exchange ratios were observed following the 102% trial. As the pace of trials increased, stroke rate was found to increase proportionately with stroke count. However, during the latter stages of the 100% trial, a disproportionate increase in the stroke count was observed, which led to a significant pacing error. This feature was more obvious in the 102% trial, where participants demonstrated 'positive pacing' and reported higher ratings of perceived exertion than for the 98% trial. During the early stages of the trials, turning times were initially shorter the faster the pace of the trial; however, as the trials progressed, this pattern was found to reverse. We conclude that a slight reduction in pace during near maximal breaststroke swimming altered kinematic but not post-exercise metabolic responses, while an increase in pace led to positive pacing and an increase in both kinematic responses and anaerobic metabolism.  相似文献

Cognitive Attributes,Attention, and Self‐Efficacy of Adequate and Inadequate Responders in a Fourth Grade Reading Intervention          下载免费PDF全文

Eunsoo Cho  Garrett J. Roberts  Philip Capin  Greg Roberts  Jeremy Miciak  Sharon Vaughn 《Learning disabilities research & practice》2015,30(4):159-170

We examined cognitive attributes, attention, and self‐efficacy of fourth grade struggling readers who were identified as adequate responders (n = 27), inadequate responders with comprehension only deficits (n = 46), and inadequate responders with comprehension and word reading deficits (n = 52) after receiving a multicomponent reading intervention. We also included typical readers (n = 40). These four groups were compared on measures of nonverbal reasoning, working memory, verbal knowledge, listening comprehension, phonological awareness, and rapid naming as well as on teacher ratings of attention problems and self‐reported self‐efficacy. The two inadequate responder groups demonstrated difficulties primarily with verbal knowledge and listening comprehension compared to typical readers and adequate responders. Phonological awareness and rapid naming differentiated the two inadequate responder groups. In addition, both inadequate responder groups showed more attention problems and low self‐efficacy compared to typical readers.  相似文献   

‘It’s a bit of a generalisation,but …’: participant perspectives on intercultural group assessment in higher education     

Paul Moore  Greg Hampton 《Assessment & Evaluation in Higher Education》2015,40(3):390-406

This paper reports on domestic and international students’ perceptions of the influence of group diversity on communication, learning, task performance and assessment grades. The study’s methodology involved quantitative and qualitative analysis of surveys (N?=?312), focus group interviews of students (n?=?26) and individual staff interviews (N?=?7). More domestic (79%) than international (29%) students stated that they preferred working with students from a similar background. While a proportion of the sample of domestic students stated that intercultural group work raised their awareness of interaction styles in other cultures, others noted that the group experience was negatively affected by issues related to language proficiency and awareness of academic requirements. Qualitative analysis reveals that ‘othering’, a process by which members of an in group (Us) distance themselves from an outgroup (Them), was often used as a basis for these students avoiding intercultural group assessment. Finally, there was a clear pattern overall of higher achieving international and domestic students perceiving that their grades for group assignments were below what they would normally receive for individual assignments, and lower achieving students perceiving that their grades were higher for group assignments.  相似文献

Creative graduate pathways within and beyond the creative industries     

Ruth Bridgstock  Ben Goldsmith  Jess Rodgers  Greg Hearn 《Journal of Education & Work》2015,28(4):333-345

This special issue explores the nuances of graduate creative work, the kinds of value that creative graduates add through work of various types, graduate employability issues for creative graduates, emerging and developing creative career identities and the implications for educators who are tasked with developing a capable creative workforce. Extant literature tends to characterise creative careers as either ‘precarious’ and insecure, or as the engine room of the creative economy. However, in actuality, the creative workforce is far more heterogeneous than either of these positions suggest, and creative careers are far more complex and diverse than previously thought. The task of creative educators is also much more challenging than previously supposed. In this introductory article, we commence by providing a brief overview of the creative labour debates, and the evidence for each position. We present the latest literature in this area that starts to speak to how diverse and complex the landscape of creative work actually is. We then introduce each of the articles in this special issue and indicate how they contribute to a more multi-faceted picture of creative activity, and the lives and career trajectories of graduates from creative degrees.  相似文献

Self-reported ability assessment in rock climbing   总被引：1，自引：1，他引：0  

Draper N  Dickson T  Blackwell G  Fryer S  Priestley S  Winter D  Ellis G 《Journal of sports sciences》2011,29(8):851-858

Level of ability within rock climbing is generally expressed in terms of a "best ascent", rated using various grading systems within the sport. The most common method of obtaining this information is via self-report. The aim of this study was to examine the validity of self-reported climbing grades. Twenty-nine competitive rock climbers (17 males, 12 females) were first asked to report their current (defined as within the last 12 months) best on-sight lead ascent grade (Aus/NZ). The participants then climbed a specifically designed indoor route, under on-sight conditions (one attempt, no route practice or preview), to obtain an assessed grade. The route increased in difficulty, and was such that the distance achieved by the climber corresponded to a particular grade. The mean (±standard deviation) self-reported and assessed grade was 22.6?±?3.4 and 22.0?±?3.0 (Aus/NZ) respectively. Despite slight over- and underestimations in males and females respectively, there was no statistically significant difference between self-reported and assessed on-sight climbing grades. The results of this study suggest that self-reported climbing grades provide a valid and accurate reflection of climbing ability.  相似文献
