Knowing is an enacted, communicated process that is difficult to observe, let alone manage, in organizations. Communities of practice (CoPs) offer a productive solution for improving knowledge and knowledge management, but the communicative processes that enact CoPs have not been explored, leaving CoPs as an organizational black box. This research extends CoP theory as a means to determine the presence of a CoP and distinguish between various CoPs, and as a practical means to evaluate the communicative processes of organizational knowledge. CoPs enact the communicative nature of knowing through the elements of mutual engagement, negotiation of a joint enterprise, and shared repertoire. Specifically, two groups of volunteers are examined through a combination of participation, observation, and interviews in order to explore CoP theory as a dynamic system for examining and evaluating organizational knowledge.  相似文献

Trade in cultural products has traditionally been constrained by a combination of law and technology. In Europe, digital sellers based in a given EU country are not always able to distribute across borders. In January 2016, US-based Netflix announced an expansion to 243 countries, accomplishing cross-border distribution through business strategy. Changes in law or technology that facilitate cross-national cultural trade have traditionally drawn the concern of observers worried about the cultural heritage—and products—of small markets. The expansion raises questions about what Netflix is doing. Is it a cultural hegemon, distributing US fare into 243 countries? Or it is a facilitator of free trade, making the products of even small countries more available outside their home markets (relative to traditional distribution)? And how does the curated model—which limits the number of movies the platform wants to distribute—affect Netflix’s function? To shed light on these questions, we develop a new measure of the global availability of a repertoire, the value-weighted geographic reach. Using this measure we find, first, that Netflix makes many of the works from a wide variety of countries available in many other countries. Second, we find that theatrical distribution strongly advantages US-origin fare. Third, the pattern of origin repertoire available through Netflix also favors the USA, although less overwhelmingly. Moreover, many countries are relatively advantaged by their Netflix availability patterns. Finally, we discuss some issues related to the Netflix platform, including horizontal competition with other platforms, vertical struggles with content providers (and its backward integration into production), and we speculate on possible challenges for regulators.  相似文献

Each year millions of children are enrolled in center-based childcare. Childcare employees are tasked with handling over half the children’s weekly meals. Proper food handling practices are crucial in mitigating this high-risk population’s risk of foodborne illness. The purpose of this study was to identify childcare food handling employees’ (n?=?278) perceived barriers and motivators to follow recommended food safety practices. Six important barriers and 14 key motivators to following recommended food safety practices were identified. Important barriers pertained to time restraints, workloads, and lack of understanding of the importance of following proper food safety practices. Key motivators were focused on children’s safety, available supplies, communication, and food safety training/information. Employee and facility characteristics were shown to influence perceived importance of barriers and motivators to following food safety practices. Childcare directors should review scheduling and job duties of employees as the majority of identified barriers focused on “work pace” and “time restraints.” Directors should also attempt to increase food safety communication through practical situational training, written food safety policies, and use of food safety signage to increase understanding of the importance of proper food safety practices. Ensuring proper supplies are available is necessary.  相似文献

This autoethnographic self-study describes my interpretations of multicultural awareness, with special attention to multilingual awareness (MLA), based on my interactions with 52 students in the context of two literacy courses over a period of one year. An autoethnographic self-study provided an avenue to harness my reflections on practice and to study the ways in which my practice reflected awareness of my role as an educator. Findings from my teaching videos, written responses to students, and student evaluations suggested that my communication patterns with students reflected certain elements of multicultural awareness, as displayed by my attention to individual predispositions, cultural practices and personal stereotypes. The findings also appeared to indicate that multicultural and MLA interacted to reflect facilitation and symbiosis. Facilitation seemed apparent in my awareness of differences among students’ cultures and my own as I monitored my linguistic processing. Symbiosis appeared to emanate from the recognition of how my response to individual predispositions facilitated my application of conversational strategies based on feedback. This, in turn, heightened my attention to stereotypical attitudes and behaviors. Implications for multicultural teacher education include the benefits of using autoethnographic self-study to scrutinize educators’ awareness in practice as they determine the impact of this awareness on their instructional roles in multicultural teacher education. By extension, the study suggests that autoethnographic self-study research can provide additional lenses through which to interrogate monolithic perceptions of diversity in multicultural teacher education.  相似文献

Introductory biology courses form a cornerstone of undergraduate instruction. However, the predominantly used lecture approach fails to produce higher-order biology learning. Research shows that active learning strategies can increase student learning, yet few biology instructors use all identified active learning strategies. In this paper, we present a framework to design biology instruction that incorporates all active learning strategies. We review active learning research in undergraduate biology courses, present a framework for organizing active learning strategies, and provide clear implications and future research for designing instruction in introductory undergraduate biology courses.  相似文献

Cross-cultural immersion experiences have been considered to be an effective way to prepare American pre-service teachers for culturally responsive pedagogical practices. The literature review shows few studies have investigated pre-service teachers' cross-cultural experiences in non-English speaking countries, specifically Asian countries. This qualitative study examined ten American elementary pre-service teachers' teaching and learning experiences in China. Five themes emerged from the data analysis: understanding and respecting Chinese culture; developing empathetic dispositions towards non-English speaking students; exchanging teaching strategies and resources; reflecting on professional and personal growth; and initiating a proactive stance as culturally responsive change agents. Additionally, the study revealed that having two separate Chinese field placements may have differing pre-service teachers' teaching and learning experiences. Varying types of opportunities to study abroad are on the rise. Recommendations are provided for the type of cultural immersion experience that encourages neophyte educators to not only learn about others, but also learn from and with others.  相似文献

The study tested phonemic awareness in the two languages of Russian (L1)–Hebrew (L2) sequential bilingual children (N = 20) using phoneme deletion tasks where the phoneme to be deleted occurred word initial, word final, as a singleton, or part of a cluster, in long and short words and stressed and unstressed syllables. The experiments were designed to test the effect of four linguistic factors on children’s phoneme deletion: phoneme position (initial, final), linguistic context (singleton, cluster), word length and stress. The results indicated that word length and stress confirmed previous findings in other languages demonstrating the universal validity of these factors. However, phoneme position and linguistic context gave rise to novel findings in the languages studied and provided evidence for language-specific effects on phonemic awareness reflecting onset-rime versus body-coda syllable structure differences. The results are discussed within the framework of universal versus language-specific constraints on phonemic awareness performance in different languages.  相似文献

Abstract

Australian football is an indigenous game codified in 1859. In Melbourne, the code’s birthplace, the game remained officially committed to the amateur ideal for over a half-century. Illegal player payments nonetheless became increasingly commonplace. Moreover, periodically rumours swirled of champion footballers taking bribes to ‘play dead’. By the early 1900s, the code’s leading competition, the Victorian Football League (VFL), was derided with the ‘shamateurism’ label. Following a sensational match-fixing investigation that resulted in two players receiving five-year bans, in 1911 the VFL expunged its rule prohibiting player payments. Was the timing merely coincidental or was the League’s historic switch to professionalism a deliberate countermeasure to redirect press attention, renew public confidence, and restore the game’s integrity? By consulting the League’s official records and contemporary press articles, this work examines the overlooked yet discernible linkages between rising match-fixing allegations and the VFL’s decision to eschew amateurism and embrace professionalism. It argues that Australian football offers an instructive historical perspective of a sporting body tackling mounting concerns over corruption, taking back the ascendency by amending its rules to better govern over dishonest players and duplicitous club officials, thereby growing its popularity and restoring public perception of its integrity in the process.  相似文献

Abstract

In spite of the increased acceptance of artificial turf in football, few studies have investigated if matches are altered by the type of surface used and no research has compared physiological responses to football activity on artificial and natural surfaces. In the present study, participants performed a football match simulation on high-quality artificial and natural surfaces. Neither mean heart rate (171 ± 9 beats · min?1 vs. 171 ± 9 beats · min?1; P > 0.05) nor blood lactate (4.8 ± 1.6 mM vs. 5.3 ± 1.8 mM; P > 0.05) differed between the artificial and natural surface, respectively. Measures of sprint, jumping and agility performance declined through the match simulation but surface type did not affect the decrease in performance. For example, the fatigue index of repeated sprints did not differ (P > 0.05) between the artificial, (6.9 ± 2.1%) and natural surface (7.4 ± 2.4%). The ability to turn after sprinting was affected by surface type but this difference was dependent on the type of turn. Although there were small differences in the ability to perform certain movements between artificial and natural surfaces, the results suggest that fatigue and physiological responses to football activity do not differ markedly between surface-type using the high-quality pitches of the present study.  相似文献
