Where are the world's organizations headed? What do they see as their primary destination and contribution? What do they commit to deliver and to whom? How rigorous are they in defining their destinations? What label do they use to describe statements of their intended future? To find the answers to these and other questions, we examined 26 of the leading organizations internationally as well as 60 leading organizations in the United States. Based on this sample of world organizations, we found indications that many organizations see some aspect of societal good as basic to their future, while many others regard their own organization's well-being as what is most important. We find no clear favorite for what organizations label their statements of purpose: most use “mission” while some use “vision,” and some use “values” or “philosophy.” Few of the organizations in our sample state their intended destination in measurable performance terms. From these data, we discuss the implications in terms of an increasing emphasis in the literature on organizations having to deliver outputs that contribute to external clients and society. We also note that purpose statements must be accompanied by appropriate actions to achieve those intentions. In addition, we discuss how this move toward socially-responsive organizations is impacting the role of the performance technologist.  相似文献

This study examined to what extent adolescents’ and their friends’ risk behaviors (i.e., delinquency and alcohol use) hinder or promote their academic achievement (grade point average [GPA]), and vice versa. Longitudinal data were used (= 1,219 seventh- to ninth-grade adolescents; Mage = 13.69). Results showed that risk behaviors negatively affected adolescents’ GPA, whereas GPA protected against engaging in risk behaviors. Moreover, adolescents tended to select friends who have similar behaviors and friends’ behaviors became more similar over time (same-behavior selection and influence). Furthermore, although same-behavior effects seemed to dominate, evidence was found for some cross-behavior selection effects and a tendency in seventh grade for cross-behavior influence effects. Concluding, it is important to investigate the interplay between different behaviors with longitudinal social network analysis.  相似文献

Many prominent intelligence tests (e.g., Wechsler Intelligence Scale for Children, Fifth Edition [WISC-V] and Reynolds Intellectual Abilities Scale, Second Edition [RIAS-2]) offer methods for computing subtest- and composite-level difference scores. This study uses data provided in the technical manual of the WISC-V and RIAS-2 to calculate reliability coefficients for difference scores. Subtest-level difference score reliabilities range from 0.59 to 0.99 for the RIAS-2 and from 0.53 to 0.87 for the WISC-V. Composite-level difference score reliabilities generally range from 0.23 to 0.95 for the RIAS-2 and from 0.36 to 0.87 for the WISC-V. Emphasis is placed on comparisons recommended by test publishers and a discussion of minimum requirements for interpretation of differences scores is provided.  相似文献

那是一个充满忧伤的清晨。准备的各种食物的香味通常将标志着某个欢庆的节日或者是亲属的聚会,那时才赶着做这些东西,但这天清晨完全是另一回事。我从床上爬起来,尽最大努力只为面对这一天时,全身强烈地感到一阵未曾有过的寒冷。那是我宁愿很快忘却的一天,但不幸的是,我无法忘却。  相似文献

Using network analysis we investigated faculty hiring at 21 U. S. News top-ranked programs in higher education administration. Our research questions were as follows. Do top programs hire from each other? Are faculty from the “outside” finding positions at top programs? Mixed results hint at implications for the “health” of the hiring network. Closed systems in higher education may produce unintended consequences as graduate programs look to expand into new global markets.  相似文献

This study examined the metabolic cost (METs) of performing object projection skills at three practice trial intervals (6, 12, and 30 seconds). Forty adults (female n = 20) aged 18–30 (M = 23.7 ± 2.9 years) completed three, nine-minute sessions of skill trials performed at 6, 12, and 30 second intervals. Participants performed kicking, throwing and striking trials in a blocked schedule with maximal effort. Average METs during each session were measured using a COSMED K4b2. A three (interval condition) X two (sex) ANOVA was conducted to examine differences in METs across interval conditions and by sex. Results indicated a main effect for interval condition (F(5,114) = 187.02, < .001, η2 = 0.76) with decreased interval times yielding significantly higher METs [30 sec = 3.45, 12 sec = 5.68, 6 sec = 8.21]. A main effect for sex (F(5, 114) = 35.39, < .001, η2 = 0.24) also was found with men demonstrating higher METs across all intervals. At a rate of only two trials/min, participants elicited moderate physical activity, with 12 and 6-second intervals exhibiting vigorous PA. Demonstrating MVPA during the performance of object projection skill performance has potential implications for PA interventions.  相似文献

The efforts to improve the quantitative reasoning (quantitative literacy) skills of college students in the United States have been gaining momentum in recent years. At the same time, the blended learning approach to course delivery has gained in popularity, promising better learning with flexible modalities and pace. This paper presents the results of an exploratory study that compares student learning outcomes and student attitudes over several semesters of blended versus traditional delivery in the upper-division quantitative literacy course at Point Loma Nazarene University.  相似文献

An environmental education (EE) consortium located in the pacific northwest United States coalesced an external evaluation team to research its K-5 EE programming. The purpose of this article is to describe one phase of this program evaluation process including the exploration of adult stakeholder perceptions of EE programming accessed by 4th grade children. The author highlights the goals of the consortium and the context for the program evaluation, and the relevant literature addressing adult perspectives on EE is reviewed. The study framing, method, and qualitative results are reported. Findings suggest that adult stakeholders perceived positive impacts from 4th grade participation in EE, though the programming was viewed as being most beneficial to children coming from economically disadvantaged families. Implications for EE practice and research are discussed.  相似文献
