Since Teece's seminal paper explaining who were the gainers from technological innovation, increased globalization and the information and communication technology revolution have brought new ways for firms to organize and appropriate from innovation. A new more open model of innovation suggests that firms can benefit from sources of innovation that stem from outside the firm. The central theme of this paper is how firms try to unlock communities as complementary assets. These communities exist outside firm boundaries beyond ownership or hierarchical control. Because of practices developed by communities to protect their work, firms need to assign individuals to work in these communities in order to gain access to developments and, to an extent, influence the direction of the community. Using network analysis we show that some software firms sponsor individuals to act strategically within a free and open source software (FOSS) community. Firm sponsored individuals interact with more individuals than interact with them, and also they seek to interact with central individuals in the community. However, we can see differences in how individuals interact, depending on whether their affiliation is with a dedicated FOSS firm or an incumbent in the software industry. Apparently, some firm managers believe they need ‘a man on the inside’ to be able to gain access to communities.  相似文献

This paper analyzes organizations’ attempts to entice external contributors to submit suggestions for future organizational action. While earlier work has elaborated on the advantages of leveraging the knowledge of external contributors, our findings show that organizational attempts to attract such involvement are likely to wither and die. We develop arguments about what increases the likelihood of getting suggestions from externals in the future, namely through (1) proactive attention (submitting internally developed suggestions to externals to stimulate debate) and (2) reactive attention (paying attention to suggestions from externals to signal they are being listened to), particularly when those suggestions are submitted by newcomers. Findings from an analysis of about 24,000 initiatives by organizations to involve external contributors suggest these actions are crucial for receiving suggestions from external contributors. Our results are contingent upon the stage of the initiative because organizations’ actions exert more influence in initiatives that lack a history of prior suggestions. Our work has implications for scholars of open innovation because it highlights the importance of considering failures as well successes: focusing exclusively on initiatives that reach a certain stage can lead to partial or erroneous conclusions about why some organizations engage external contributors while others fail.  相似文献

Banana is an important crop grown in Oman and there is a dearth of information on its genetic diversity to assist in crop breeding and improvement programs.This study employed amplified fragment length polymorphism(AFLP) to investigate the genetic variation in local banana cultivars from the southern region of Oman.Using 12 primer combinations,a total of 1094 bands were scored,of which 1012 were polymorphic.Eighty-two unique markers were identified,which revealed the distinct separation of the seven cultiva...  相似文献

Recently, in the wake of the Bologna Declaration and similar international initiatives, there has been a rapid increase in the number of university courses and programmes taught through the medium of English. Surveys have consistently shown the Nordic countries to be at the forefront of this trend towards English-medium instruction (EMI). In this paper, we discuss the introduction of EMI in four Nordic countries (Denmark, Finland, Norway and Sweden). We present the educational setting and the EMI debate in each of these countries and summarize relevant research findings. We then make some tentative suggestions for the introduction of EMI in higher education in other countries. In particular, we are interested in university language policies and their relevance for the day-to-day work of faculty. We problematize one-size-fits-all university language policies, suggesting that in order for policies to be seen as relevant they need to be flexible enough to take into account disciplinary differences. In this respect, we make some specific suggestions about the content of university language policies and EMI course syllabuses. Here we recommend that university language policies should encourage the discussion of disciplinary literacy goals and require course syllabuses to detail disciplinary-specific language-learning outcomes.  相似文献

Abstract

Two hundred high school and college students were paired to compete in two game abstracts to determine the effect of “game strategy” on winning two-person, zero-sum, finite strategy games involving a motor skill and to determine the effect of play experience on rational decision making. Subjects competed in eight series of ten plays for a total of 8,000 plays, under the following conditions: play vs. play, play-skill vs. play-skill, strategy-skill vs. play-skill, strategy vs. play, play-skill vs. strategy-skill, play vs. strategy, strategy vs. strategy, and strategy-skill vs. strategy-skill. Results indicate that “game strategy” contributes significantly to the winning of two-person, zero-sum, finite strategy games involving a motor skill and that rational decision making improves through experience. Within the limitations of this study it was concluded that play experience contributes to rational decision making in simple strategy games while “game strategy” is beneficial to winning complex strategy games.  相似文献

The aim of this article is to contribute to the discussion on how examinations can be designed to enhance students’ learning and increase throughput in terms of the number of students who sit, and pass, the course examination. The context of the study is a basic level political science course on power analysis, which initially suffered from low throughput. The contribution of the article is to demonstrate that no other changes to the course than the introduction of an element of meta-reflection in the take-home examination – a so-called ‘reflection exercise’ – helped increase throughput by 70–80%. The aggregated performance of the students was thus significantly enhanced after they were explicitly encouraged to meta-reflect on problems posed in the take-home examination, and on different strategies for tackling these problems. The introduction of another meta-reflection exercise in the mandatory seminars did not further increase throughput, but made a qualitative difference in terms of the positive feedback that students received on their work.  相似文献

Many universities have developed large-scale interdisciplinary research centers to address societal challenges and to attract the attention of private philanthropists and federal agencies. However, prior studies have mostly shown that interdisciplinary centers relate to a narrow band of outcomes such as publishing and grants. Therefore, we shift attention to include outcomes that have been the centers mandate to influence ? namely outreach to the media and private industry, as well as broader research endeavors and securing external funding. Using data covering Stanford University between 1993 and 2014, we study if being weakly and strongly affiliated with interdisciplinary centers in one year relates to and increases (1) knowledge production (publications, grants and inventions), (2) instruction (numbers of students taught, PhDs and postdocs advised), (3) intellectual prominence (media mentions, awards won and centrality within the larger collaboration network), and (4) the acquisition of various sources of funding in the next year. Our results indicate that interdisciplinary centers select productive faculty and increase their activity on a broad range of outcomes further, and in ways greater than departments and traditional interdisciplinary memberships, such as courtesy and joint appointments.  相似文献

ABSTRACT

This study aimed to investigate the impact of mental fatigue on soccer-specific decision-making. Twelve well-trained male soccer players performed a soccer-specific decision-making task on two occasions, separated by at least 72 h. The decision-making task was preceded in a randomised order by 30 min of the Stroop task (mental fatigue) or 30 min of reading from magazines (control). Subjective ratings of mental fatigue were measured before and after treatment, and mental effort (referring to treatment) and motivation (referring to the decision-making task) were measured after treatment. Performance on the soccer-specific decision-making task was assessed using response accuracy and time. Visual search behaviour was also assessed throughout the decision-making task. Subjective ratings of mental fatigue and effort were almost certainly higher following the Stroop task compared to the magazines. Motivation for the upcoming decision-making task was possibly higher following the Stroop task. Decision-making accuracy was very likely lower and response time likely higher in the mental fatigue condition. Mental fatigue had unclear effects on most visual search behaviour variables. The results suggest that mental fatigue impairs accuracy and speed of soccer-specific decision-making. These impairments are not likely related to changes in visual search behaviour.  相似文献
