Understanding the social processes that support innovations in new biotechnologies presents an interesting challenge. Evidence from the Australian bioindustry reveals how the development and integration of new biotechnologies is a dynamic social process. Our findings highlight how new technology acceptance and integration rested on the micro‐politics of sense‐making and relational networking. 相似文献

Technology education is a new school subject in comparison with other subjects within the Swedish compulsory school system. Research in technology education shows that technology teachers lack experience of and support for assessment in comparison with the long-term experiences that other teachers use in their subjects. This becomes especially apparent when technology teachers assess students’ knowledge in and about technological systems. This study thematically analysed the assessment views of eleven technology teachers in a Swedish context. Through the use of in-depth semi-structured qualitative interviews, their elaborated thoughts on assessing knowledge about technological systems within the technology subject (for ages 13–16) were analysed. The aim was to describe the teachers’ assessment views in terms of types of knowledge, and essential knowledge in relation to a progression from basic to advanced understanding of technological systems. The results showed three main themes that the interviewed teachers said they consider when performing their assessment of technological systems; understanding (a) a system’s structure, (b) its relations outside the system boundary and (c) its historical context and technological change. Each theme included several underlying items that the teachers said they use in a progressive manner when they assess their students’ basic, intermediate and advanced level of understanding technological systems. In conclusion, the results suggest that the analysed themes can provide a basis for further discussion about defining a progression for assessing students’ understanding about technological systems. However, the findings also need to be examined critically as the interviewed teachers’ views on required assessment levels showed an imbalance; few students were said to reach beyond the basic level, but at the same time most assessment items lay on the intermediate and advanced levels. 相似文献

Self-efficacy influences students’ activities, effort and persistence, and it can help predict their motivation and academic performance. This study attempts to investigate the relationship between self-efficacy, preferred learning methods, and academic performance under different learning methods in a unique hospitality course setting. The results indicate that hospitality management students prefer a “learn by doing” approach instead of computer-based learning and lecturing. This study concludes that self-efficacy affects the academic performance in both lecturing and practical learning in hospitality education. However, students’ preference in terms of learning methods does not influence their academic performance. Emphasizing “learn by doing” in the hospitality higher education curriculum is recommended in addition to recruiting faculty members with extensive industry experience. Conversely, it is recommended that faculty find the means to increase students’ self-efficacy when adopting different teaching approaches. 相似文献

This paper shows how international capital flows originate boom‐bust and sunspot episodes in a neoclassical growth model of a small, open economy. A limit is imposed on how much the economy can borrow from foreign creditors and it is made endogenous by assuming that the debt‐to‐GDP ratio is procyclical. The steady state is locally indeterminate when the credit multiplier is larger than some threshold level, whereas saddle‐point stability prevails when the credit multiplier is low enough. As a consequence, high levels of the credit multiplier lead to both booms followed by busts and sunspot‐driven volatility near the steady state, while, in contrast, low levels ensure monotonic convergence. Compared with saddle‐path equilibria, boom‐bust and sunspot equilibria are associated with both lower welfare and debt overhang, that is, a crowding‐out effect of credit: when the economy is highly leveraged, it uses savings to cut down foreign debt, at the expense of both human and physical investment. Numerical examples show that indeterminacy arises for debt‐to‐GDP ratios that fall within the range of available estimates. Finally, the effects of shocks to the world interest rate on output and consumption are amplified and persistent in the debt overhang regime. 相似文献

Recent literature suggests that a proactive exchange rate policy in accordance with price incentives (i.e. undervaluation) can foster manufactured exports and growth. This paper is built on these recent developments and investigates, using a sample of 52 developing countries, whether such a proactive exchange rate policy is adopted. The results show that during the period 1991–2005 a number of countries has used undervaluation to foster the price competitiveness of manufactured exports. 相似文献

We view a game abstractly as a semiparametric mixture distribution and study the semiparametric efficiency bound of this model. Our results suggest that a key issue for inference is the number of equilibria compared to the number of outcomes. If the number of equilibria is sufficiently large compared to the number of outcomes, root‐n consistent estimation of the model will not be possible. We also provide a simple estimator in the case when the efficiency bound is strictly above zero. 相似文献

In the contract-theoretic literature, there is a vital debate about whether contracts can mitigate the hold-up problem, in particular when renegotiation cannot be prevented. Ultimately, this question has to be answered empirically. As a first step, we have conducted a laboratory experiment with 960 participants. We consider investments that directly benefit the non-investing party. While according to standard theory, contracting would be useless if renegotiation cannot be ruled out, we find that option contracts significantly improve investment incentives compared to a no-contract treatment. This finding might be attributed to Hart and Moore?s (2008) recent idea that contracts can serve as reference points. 相似文献

Corporate codes of conduct are a practical corporate social responsibility (CSR) instrument commonly used to govern employee
behavior and establish a socially responsible organizational culture. The effectiveness of these codes has been widely discussed
on theoretical grounds and empirically tested in numerous previous reports that directly compare companies with and without
codes of conduct. Empirical research has yielded inconsistent results that may be explained by multiple ancillary factors,
including the quality of code content and implementation, which are excluded from analyses based solely on the presence or
absence of codes. This study investigated the importance of code content in determining code effectiveness by examining the
relationship between code of conduct quality and ethical performance. Companies maintaining high quality codes of conduct
were significantly more represented among top CSR ranking systems for corporate citizenship, sustainability, ethical behavior,
and public perception. Further, a significant relationship was observed between code quality and CSR performance, across a
full range of ethical rankings. These findings suggest code quality may play a crucial role in the effectiveness of codes
of conduct and their ability to transform organizational cultures. Future research efforts should transcend traditional comparisons
based on the presence or absence of ethical codes and begin to examine the essential factors leading to the effective establishment
of CSR policies and sustainable business practices in corporate culture. 相似文献

In this paper, we examine the strategic use of debt in franchise organizations. We focus on both the franchisee's and the franchisor's capital structures. The primary goal of this study is to examine whether franchisors impose limits on franchisees’ debt levels to be able to increase their own leverage. We find that the franchisor's leverage is significantly related to the maximum leverage allowed for the franchisee. As the franchisor sets an upper limit on the franchisee's debt ratio, the franchisor can raise more debt and therefore seizes tax benefits, since interest payments are tax deductible. We find that this effect is stronger in chains with larger fractions of franchised outlets. 相似文献
