This essay builds on the growing, but underdeveloped, role of communication in work based on Social Identity Theory (SIT) as it relates to identity and identification in the organization. Five existing areas of connection between communication and SIT in organizational identification research are documented and assessed. These include salience of dual/multiple identifications, computer-mediated communication and virtual work related to identification, relationally focused work identities, organizational-level identities, and disidentification and related forms.  相似文献

Abstract

In the fall of 2017, the Clark Library at the University of Portland undertook an investigation of ethics in academic libraries to understand ethical practices in the library’s day-to-day work. The self-study was a year-long, library-wide project with directed activities within small groups, individually assigned readings and responses, and discussions at all-staff meetings. The project culminated in three specific deliverables: an annotated bibliography focused on ethical issues by functional area, a Clark Library Statement of Ethics, and a Statement of Ethical Information Use for inclusion in University syllabi.  相似文献

This study examined the skill involvements of three positional groups across a junior representative rugby league season. Data were collected from 45 rugby league players (mean ± SD; age = 16.5 ± 1.0 years) currently participating in the Harold Matthews and SG Ball Cup. Players were subdivided into hit-up forwards, adjustables and outside backs. The frequency (n · min?1) of offensive, defensive and overall involvements was coded for each group using a notation system and a practical coach skill analysis tool. Multivariate analysis of variance (MANOVA) revealed a significant effect of playing position on skill involvements (F = 9.06; P < 0.001; ES = 0.41). Hit-up forwards performed a significantly greater frequency of offensive (0.31 ± 0.10), defensive (0.42 ± 0.15) and overall involvements (0.74 ± 0.19) when compared to adjustables (0.20 ± 0.08, 0.28 ± 0.08 and 0.52 ± 0.15, respectively) and outside backs (0.20 ± 0.12, 0.11 ± 0.07 and ± 0.31 ± 0.17, respectively). Further, adjustables performed a significantly greater number of defensive (0.28 ± 0.08) and overall involvements (0.52 ± 0.15) when compared to outside backs (0.11 ± 0.07 and 0.31 ± 0.17, respectively). The findings of this study suggest that it is important to consider a junior player’s positional group when analysing their skill involvements. Information gained from this study could assist in the design of specific training methodologies for junior rugby league players in high-level talent development programmes.  相似文献

The purpose of this article was to examine the validity of self-reported pedometer steps/day. Forty-seven participants were provided a New Lifestyles NL-2000 (NL-2000; Lees Summit, MO, USA) pedometer and a physical activity (PA) diary for 3 weeks, but not informed of the data-storing capabilities. For weeks 2 and 3, each participant was given a step goal of 3,000 steps/day above week 1 average. A 2 × 3 repeated measures analysis of variance (ANOVA) was used to examine differences between reported steps/day. Bland–Altman plots assessed the mean bias and limits of agreement between reporting methods. Mean self-reported and NL-2000 steps/day were 9,264 ± 3,555 and 8,971 ± 3,590 steps/day (n = 26, p > .05). Mean biases were 216 ± 1,753 (week 1), –506 ± 1,355 (week 2), and –590 ± 1,360 (week 3) steps/day. Negative mean bias values indicate higher self-reported steps/day. Mean steps/day were similar between recording methods, but large differences were observed among individuals, suggesting self-reported steps/day may be valid for PA research at the population level, but not the individual level.  相似文献

The use of colour in the metallographic examination of ancient metals is useful both for research and teaching purposes. Application of different optical methods of examination include: polarized light, with or without a first-order red compensator, and differential interference contrast microscopy (DIC). The use of DIC can be combined with the other techniques mentioned in the text for the examination of etched or unetched metal surfaces, which are best observed microscopically using a metallograph. Colour techniques are now used routinely in industrial metallography, and are available for a variety of metals and alloys. Colour tint etching can be used to enhance grain structure or different phases present in the metallic artefact which may not be visible in conventional etched samples, or which lack optical contrast. Many more applications of these techniques in the examination of ancient metals will be published in the literature as they become better known and second-hand equipment with DIC lenses enter the market at a price suitable for conservation laboratories to purchase them.  相似文献

Despite the ‘practice’ turn in the broader management literature, very little work in educational administration has engaged in a theoretical discussion about what constitutes leadership practice. Theoretically informed by the French sociologist Pierre Bourdieu, this paper contributes to the long-established critical tradition in the educational administration literature, to argue that: (i) ‘leadership’ is a label of the managerialist project of the state; (ii) leadership should be thought of as a disruptive practice; and (iii) Bourdieusian theory can enable this thinking, but not as it is frequently mobilised in the educational administration literature. The alternative put forth in this paper is not merely replacing one external narrative (managerialism) with another (Bourdieusian), but rather advancing a theoretical position on what is leadership that paves a way forward for a research programme.  相似文献

Unlike many other high-stakes exams which test students only at the end of a course, the English A levels use a modular format where students are allowed to resit past units within the course. Since the introduction of resits for A levels in 2000, the A level results have been improving significantly and resits are seen as the main reason for the big increases. Using the findings of research based on the accounts of students and teaching staff, this article examines some of the less obvious effects of resits on student learning than that reflected by exam results in terms of students’ approach to learning. It concludes that allowing unlimited resits in high-stakes exams could produce some undesirable consequences for student learning and could be unfair and unfit for the purposes of the exam.  相似文献

Six hundred fifty‐one students (ages 11–18) completed a questionnaire that asked if they were taking stimulant medication for ADHD. Those who responded positively were then asked to answer a section of the questionnaire that asked them about their experiences and attitudes related to their treatment with the medication. If they responded that they were not diagnosed with ADHD and not receiving treatment with stimulant medication, they answered a section of the questionnaire that inquired about their perceptions of students who did take medication. Fifty students completed the taking‐medication portion of the questionnaire. Although the students reported that the medication helped them somewhat in the areas of behavior, social ability with friends, parents, and teachers, and attention, they reported that the medication did not help them in the area of academic achievement. The majority of the students reported some side effects from their medication. Thirty‐four percent of students taking ADHD medication reported being approached to sell or trade their medication, and 53% of students not taking ADHD medication reported that some students taking ADHD medication gave away or sold their medication. © 2001 John Wiley & Sons, Inc.  相似文献
