This paper will problematise the notion of distributed cognition in courses across cultural learning borders, by presenting a narrative case study of six learners’ journeys to online learning. I will argue that although distributed cognition is a widely acceptable theory in e‐learning, it is based on an assumption that the ‘distribution’ of cognition is reciprocal between toolmakers, texts and users, when perhaps, in certain instances, it excludes the life (and learning) world of local learners in the global, borderless environment. In these instances the cognition that is assumed to be distributed is, in contrast, ‘contained’ in the narrative‐in‐action that is familiar to the learners, whose situated knowledge is embedded and embodied in a non‐global discourse ( Henning et al., 2000 ).  相似文献

Irrigation expansion is critical to increase crop yields and mitigate effects from climate change in Sub‐Saharan Africa, but the low profitability has led to little irrigation investments in the region so far. Using an integrated modeling framework, we simultaneously evaluate the returns to irrigation arising from both economic and biophysical impact channels to understand what determines the profitability of irrigation in Malawi. Our results confirm that the returns to irrigation cannot cover the costs in Malawi. While labor‐intensive irrigation expansion leads to unfavorable structural change in the short‐run, the profitability hinges on low irrigated yields that fall far from expectations due to insufficient input use and crop management techniques. On the other hand, we find that the nonmonetary benefits of irrigation regarding higher food security, lower poverty, and reduced vulnerability to climate change make investments in irrigation worthwhile to improve the livelihoods of smallholders.  相似文献

The value that many superpaid CEO superstars supposedly created has largely disappeared, and the likelihood that it will be recovered anytime soon seems remote. On top of that, a good number of top executives treated their companies like ATMs, awarding themselves millions of dollars in corporate perks. It's hard to dispute the idea that executives were corrupted by the sums of money dangled in front of them. What's wrong with executive compensation, and what can we do about it? HBR and the University of Delaware's Center for Corporate Governance convened a round-table of compensation experts last October on the university's campus in Newark, Delaware. The 12 panelists, from CEOs to investors, from the professionals who advise them to a chief justice who rules on their disputes, provided an extraordinary diversity of viewpoints. The panelist began by debating ways to align the interests of the senior executives with the long-term interests of the company-weighing the relative benefits of stock options versus stock grants, for instance. But the discussion expanded to cover broader questions of corporate governance and company values. "The main reason compensation increases every year is that most boards want their CEO to be in the top half of the CEO peer group," said Ed Woolard,Jr., a former CEO of DuPont. And compensation lawyer Joe Bachelder pointed out the danger of structuring pay in such a way that it dampens risk taking among executives. It was a lively and wide-ranging discussion of one business's most pressing issues.  相似文献

This study examines whether the choice of amortization life for purchased goodwill is predictive of the firm's post-acquisition earnings levels, given that shorter lives could lead to a dilution in earnings. Our findings support this interpretation. Further, consistent with Andrade (2001), we demonstrate a link between post-acquisition earnings changes and stock performance. These results suggest that the amortization life chosen is a reliable predictor of the success of the acquisition both in terms of earnings changes and future stock performance. These findings are relevant since the information concerning the life chosen was eliminated by the adoption of SFAS No. 142.  相似文献

We present a broad-based, consumer-centric view of innovation—referred to as “perceived firm innovativeness” (PFI). PFI is conceptualized as the consumer's perception of an enduring firm capability that results in novel, creative, and impactful ideas and solutions. We develop and validate a PFI scale and show that PFI impacts consumer loyalty via two processing routes: a functional-cognitive route and an affective-experiential route. Our results indicate that a firm needs to consider consumer perceptions of the firm as a whole, and not just new products and technologies, and take into account a functional-cognitive perspective as well as consumer emotions and experiences.  相似文献

The authors have studied the effect of tool-making on man's evolution. They argue that growth is not exponential, but hyperbolic, and that a positive feedback exists linking technological development to population. Exploring the nature of this mechanism in order to improve the predictive capability of global models is the goal of the article.  相似文献
