This article examines ethics of consultants from the perspective of counter‐rational organizational theory. First, a set of four ethical questions, derived from Kohlberg, are presented. Second, a real consulting scenario is described, and the author's intervention is outlined. Finally, the implications of the case to consulting practice are discussed.  相似文献

The influence of 2 weeks of low-volume high-intensity interval training on health outcomes in adolescent boys

Abstract

The present study aimed to establish whether 2 weeks of high-intensity interval training would have a beneficial effect on aerobic fitness, fat oxidation, blood pressure and body mass index (BMI) in healthy adolescent boys. Ten adolescent boys (15.1 ± 0.3 years, 1.3 ± 0.2 years post-estimated peak height velocity) completed six sessions of Wingate-style high-intensity interval training over a 2-week period. The first session consisted of four sprints with training progressed to seven sprints in the final session. High-intensity interval training had a beneficial effect on maximal O₂ uptake (mean change, ±90% confidence intervals: 0.19 L · min^?1, ±0.19, respectively), on the O₂ uptake at the gas exchange threshold (0.09 L · min^?1, ±0.13) and on the O₂ cost of sub-maximal exercise (–0.04 L · min^?1, ±0.04). A beneficial effect on the contribution of lipid (0.06 g · min^?1, ±0.06) and carbohydrate (–0.23 g · min^?1, ±0.14) oxidation was observed during sub-maximal exercise, but not for the maximal rate of fat oxidation (0.04 g · min^?1, ±0.08). Systolic blood pressure (1 mmHg, ±4) and BMI (0.1 kg · m², ±0.1) were not altered following training. These data demonstrate that meaningful changes in health outcomes are possible in healthy adolescent boys after just six sessions of high-intensity interval training over a 2-week period.  相似文献   

Frozen pendulum?     

Bernard Barker 《Journal of educational administration and history》2012,44(1):65-88

This article examines the New Labour legacy in education, reviews the arguments of The Pendulum Swings in the light of contributions to this themed issue, examines early Coalition policymaking, and recommends four principles that should guide the search for a new approach to school improvement. Recent initiatives are found to be a parody of school reform, as previously understood, more likely to provoke a crisis than to sustain the last government's drive for improved effectiveness. The pendulum is poised to swing as current policies unravel.  相似文献   

A Model of Factors Contributing to STEM Learning and Career Orientation     

Gwen Nugent  Bradley Barker  Greg Welch  Neal Grandgenett  ChaoRong Wu  Carl Nelson 《International Journal of Science Education》2013,35(7):1067-1088

The purpose of this research was to develop and test a model of factors contributing to science, technology, engineering, and mathematics (STEM) learning and career orientation, examining the complex paths and relationships among social, motivational, and instructional factors underlying these outcomes for middle school youth. Social cognitive career theory provided the foundation for the research because of its emphasis on explaining mechanisms which influence both career orientations and academic performance. Key constructs investigated were youth STEM interest, self-efficacy, and career outcome expectancy (consequences of particular actions). The study also investigated the effects of prior knowledge, use of problem-solving learning strategies, and the support and influence of informal educators, family members, and peers. A structural equation model was developed, and structural equation modeling procedures were used to test proposed relationships between these constructs. Results showed that educators, peers, and family-influenced youth STEM interest, which in turn predicted their STEM self-efficacy and career outcome expectancy. STEM career orientation was fostered by youth-expected outcomes for such careers. Results suggest that students’ pathways to STEM careers and learning can be largely explained by these constructs, and underscore the importance of youth STEM interest.  相似文献   

A sociocultural analysis of mandated curriculum change: the implementation of a new senior physics curriculum in New Zealand schools     

Teresa Fernandez  Garth Ritchie  Miles Barker 《课程研究杂志》2013,45(2):187-213

We analyse the implementation of a new New Zealand physics curriculum from a socio‐cultural perspective. We explore the development of the curriculum document and examine the obstacles to its implementation. Change was compromised by the lack of any intersubjective linkage between teachers and the curriculum designers. The teachers’ own community of practice was most influential in how implementation occurred.

Curriculum change processes and discourses must be made transparent so that teachers can have a framework for ‘dereification’ of a curriculum document into their classroom practices. Without planning for teachers’ participation in the negotiation of curriculum meanings, curriculum developers themselves become marginalized, and the cultural objects they have developed will be adopted in unanticipated ways.  相似文献

THE PERSONALITY PROFILES OF CIVIL ENGINEERING STUDENTS     

Dennis Barker 《Assessment & Evaluation in Higher Education》1988,13(3):183-194

The importance of determining the personality profile of the civil engineering profession is stressed. Personality profiles for civil engineering students have been determined and compared with those of other subject areas. The personality factors were also compared with the examination performance in order to determine the extent to which penonality factors are significant in the civil engineering degree course. It was not possible to separate the top students from the bottom students in the examination on the basis of personality; a similar set of personality factors were important for both groups.  相似文献   

MUMEDALA—An approach to multi-media authoring     

Philip G Barker 《British journal of educational technology : journal of the Council for Educational Technology》1984,15(1):4-13

The MUMEDALA (MUlti-MEDia Authoring LAnguage) system is an authoring facility that is designed to enable the creation and control of a sophisticated interactive learning environment. Such an environment might contain a variety of channels that enable (1) the presentation of instructional material, and (2) the capture of student response and monitoring data. The latter provides the means of achieving highly individualized instructional schema based upon the use of a range of teaching media. This paper presents an overview of the MUMEDALA system, its design features and the progress being made towards its realization.  相似文献   

ASPIRATIONS AND YOUNG PEOPLE’S CONSTRUCTIONS OF THEIR FUTURES: INVESTIGATING SOCIAL MOBILITY AND SOCIAL REPRODUCTION     

Kate Hoskins  Bernard Barker 《British Journal of Educational Studies》2017,65(1):45-67

The United Kingdom’s Coalition government has introduced an education policy that is focused on increasing the opportunities to promote and advance social mobility for all children within state education. Raising young people’s aspirations through school-based initiatives is a prominent theme within recent policy texts, which are focused on improving educational outcomes and thus advancing social mobility. This article draws on qualitative data from paired interviews with 32 students in two academies to first investigate if our participants’ aspirations indicate a desire for intragenerational social mobility and second, to explore our participants’ perceptions of the influences of their family background on their aspirations for the future. Analysis of our data highlights the mismatch between our participants’ aspirations for the future and the government’s constructions of what they should aspire to, as articulated in policy texts. By investigating aspirations, as part of a wider project to understand social mobility qualitatively, our data shows the important role of family in shaping our participants’ varied and diverse aspirations that are frequently at variance with government policy.  相似文献
