教育地理学若干问题的思考

教育地理学作为一门新兴学科,自20世纪50年代以来国外学者就进行了研究。20世纪90年代,教育地理学在我国也受到一些学者重视。随着《教育地理学》一书的出版,教育地理学作为一门学科在我国确立起来,学者在教育地理学的研究对象、学科性质和学科体系等方面进行了研究,但随后研究势头减弱,学科发展缓慢,存在研究对象尚不明确,学科性质争论不下,学科体系尚未形成,研究团队薄弱等诸多问题。与此同时,国外的教育地理研究已经发生了教育地理研究的“空间转向”,并获得了较丰富的理论成果,值得借鉴。我国的教育地理学研究需要在理论研究、实践研究、方法论研究、科研团队建设和人才培养方面做出更进一步的努力。

CEOs’ temporal focus,firm strategic change,and performance: Insights from a paradox perspective

Recent research indicates that CEOs’ temporal focus (the degree to which individuals attend to the past, present, and future) is a critical predictor for strategic outcomes. Building on paradox theory and the attention-based view, we examine the implications of CEOs’ past and future focus for strategic change. Results from polynomial regression analysis reveal that CEOs who cognitively embrace both the past and the future at the same time engage more in strategic change. In addition, our results reveal that the positive strategic change−firm performance relationship is enhanced when CEOs’ past focus is high, whereas CEOs’ future focus mitigates the translation of strategic change into firm performance (when their past focus is low at the same time). In addition, supplemental analyses indicate that the impact of CEOs’ temporal focus turns out differently in stable and dynamic environments. Our study thus extends the literature on both individual’s temporal focus and strategic change.     

The wisdom and madness of crowds: How information networks and board cognition help or hinder firm performance across the business cycle

We know little of why a minority of firms pursue counter-cyclical strategies and consequently outperform competitors during recessions. Based on the theory of institutional isomorphism, we hypothesize that these firms avoid the mimetic and normative pressures that promote strategic convergence during uncertainty. We demonstrate these effects at the board-level in a sample of 1,615 U.S. firms. Mimetic processes are evident, with firms' connectedness in board interlock networks attenuating profitability and decreasing firm value during recessions—a reversal of the positive effects during expansions. Normative pressures arise from homogeneity in directors’ educational and professional experience, with greater consequences for long-term performance. Overall, recessionary performance is improved when firms occupy relatively isolated positions in informational networks and appoint directors from a range of backgrounds.     

The effects of pre-IPO corporate activity on newly-public firms' growth

We investigate firms' pre-IPO corporate activity. We find that firms involved in extraordinary – i.e., beyond momentum – amounts of acquisitions, JVs, and alliances in the year leading up to their IPOs (1) are more likely to engage in post-IPO corporate activity; and (2) enter into their first post-IPO transaction twice as fast as other firms. Our results indicate that signaling via extraordinary corporate activity can have a significant effect on entrepreneurial firms’ growth. The implications are discussed.     

The impact of internal communication on strategic and economic effects in Serbian companies

This paper presents the research results in relation to examining and defining dependences and the impact of internal communication on certain strategic and economic business effects. Serbian companies were the focus of this research. The data were collected by polling 100 managers from 100 companies. Afterwards, multivariate regression and correlation was carried out in the aim of the final determination of requested dependences. This research confirmed a strong positive relation between internal communication and strategic and economic business effects.     

Price-setting newsvendor with strategic consumers

We consider a newsvendor who sells a single product over a single season with the objective of determining both the selling price and stock quantity to maximize the expected profit. The customers are strategic and we consider two demand cases: additive and multiplicative. For each case, we derive the newsvendor׳s optimal decisions and demonstrate that neglecting the price-sensitivity of demand leads the newsvendor to make sub-optimal decisions. Moreover, we show that under certain conditions, strategic consumer behavior may positively affect the newsvendor׳s optimal expected profit in the additive demand case.

A Business Model Innovation Typology

An effective business model is the core enabler of any company's performance. Business model innovation is not only becoming more and more important due to increasing and globalizing competition, but also an enormous challenge, both theoretically and practically. Although many managers are eager to consider more disruptive changes to their business model, they often do not know how to articulate their existing or desired business model and, even less so, understand the possibilities for innovating it. One of the steps toward developing more theoretical insight and practical guidelines is the identification of types and the development of a typology of business model innovations. Ten retrospective case studies of business model innovations undertaken by two industrial companies provide the empirical basis for this article. We analyzed the characteristics of these innovations as well as their success rates. The findings suggest that there are indeed various business model innovation types, each with its own characteristics and challenges.
