To date, there have been a number of studies that have examined how policies move from one jurisdiction to another. However, few of these studies have examined the micro-interactive effects of actors. This is necessary to understand how actors shape outcomes over time. The aim of this paper is to engage with this micro-level literature through an empirical study of policy transfer in the field of architectural norms in hospital construction in post-Soviet states. To do this, we generate several theoretical assumptions to link the transfer literature to wider debates in the governance framework. The goal is to discover how the power of actors interacts in the policymaking processes to influence outcomes over time and in light of learning. What we hope to do is bring the interactive and dynamic effects that occur between agents attempting to shape the transfer process back into the transfer picture. The aim is to show that power flows and that these flows alter the shape and outcome of the transfer process.

When online retailers allow third-party sellers to place certain products on their platforms, these sellers become not only collaborators but also competitors. The purpose of this study is to compare the differences in price discounts between Third-Party Marketplace (3PM) sellers and Fulfilled by Walmart (FBW) sellers on Walmart.com over time. The results, based on data collected in the form of the daily prices of 54,162 products offered by Walmart during the holiday season, show that the average discount for 3PM sellers is significantly lower than that for FBW sellers. In addition, across product categories, FBW sellers had significantly higher average discounts than 3PM sellers in the electronics, housewares, and toys categories. Furthermore, the level of discount began to increase in early November and peaked around Christmas. Our findings may help retailers manage their dealings with these third-party sellers while also helping consumers to optimize their purchasing decisions.

One must, after reading the above two quotes, make up one’s own mind as to the composition of tacit knowledge, for it seems Cavusgil et al., (2003) are certainly not discussing the same tacit knowledge as von Krogh et al. (2000). The tacit knowledge studied herein is more akin to that discussed by the latter set of authors, that is to say a form of knowledge that is passed through what Nonaka and colleagues have labelled socialisation in intimate person to person settings. In time the organisation builds up a stock of such soft knowledge, which is lost when staff leave and not replaced again either until further skilled staff arrive, or the ones remaining acquire it through experience over time. Whilst earlier work in this empirical study examined the phenomenon of tacit knowledge in depth (including a multitude of definitions as revealed in Appendix A), what was ultimately settled upon for the empirical research in this study was that of articulable implicit managerial IT knowledge.

AbstractThe New Legal Realist approach to international law builds from a jurisprudential tradition that asks how actors use and apply law in order to understand how law obtains meaning, is practised, and changes over time. The article addresses the jurisprudential roots of the New Legal Realism, its core attributes, and six important components in the current transnational context. In the pragmatist tradition, the New Legal Realism is both empirical and problem-centred, attending to both context and legal normativity. What is new is the rise of transnational activity that gives rise to an enlarged scope of transnational problem-solving through international law in radically new ways across areas of law, and the growth of empirical study of these phenomena. The article concludes by addressing the potential risks of the New Legal Realist approach in terms of scientism and relativism, and it responds to them.

We propose a procedure to forecast earning of listed companies. It is a modification of method developed for forecasting series with stable seasonal patterns. The new method is motivated by the observations that seasonal patterns, which may be evolving over time and remain relative stability, arise in finance market. The method can be applied to forecast individual observations as well as the end-of-season totals. Empirical study will be conducted with data from finance market to evaluate the performance of the proposed method. The new method is proved more effective than traditional time series models.

Stack Overflow has become a fundamental element of developer toolset. Such influence increase has been accompanied by an effort from Stack Overflow community to keep the quality of its content. One of the problems which jeopardizes that quality is the continuous growth of duplicated questions. To solve this problem, prior works focused on automatically detecting duplicated questions. Two important solutions are DupPredictor and Dupe. Despite reporting significant results, both works do not provide their implementations publicly available, hindering subsequent works in scientific literature which rely on them. We executed an empirical study as a reproduction of DupPredictor and Dupe. Our results, not robust when attempted with different set of tools and data sets, show that the barriers to reproduce these approaches are high. Furthermore, when applied to more recent data, we observe a performance decay of our both reproductions in terms of recall-rate over time, as the number of questions increases. Our findings suggest that the subsequent works concerning detection of duplicated questions in Question and Answer communities require more investigation to assert their findings.

Repeated exposure to aesthetic design results in consumers experiencing satiation because of sensory satiety. In other words, being consistently exposed to aesthetic stimuli activates consumers’ sensory satiety, defined as the drop in sensory pleasure, and the resulting reduction of their value of aesthetic products ultimately leads to switching intentions. That is, sensory satiety reduces functional and emotional benefits. Furthermore, consumers are unlikely to recall every item they have consumed, and are instead likely to focus on a particular option. Thus, this study predicts that consumers can recover from satiation over time. This research proposes that both satiation and accustomedness negatively affect functional benefit. As an empirical study, the research uses a multiple regression model for two purposes: The first is to test the impact of sensory satiety on perceived benefits, and the second is to observe the change in sensory satiety over time. We find that satiation and accustomedness, as sub-dimensional scales of sensory satiety, reduce perceived benefits. The results showed that it is clear that only satiation reduced functional benefits, whereas both satiation and accustomedness reduced emotional benefits. In addition, our study confirms the change in sensory satiety over time. Consumers who have been continuously exposed to, and used, aesthetic products become accustomed to them and feel satiated. Based on these results, this study will be useful for the sustainability of the product life cycle.

This review of 45 documents demonstrates the massive evidence gap in gender relations in Afghanistan agriculture. Women face greater constraints than men in generating an income from agriculture, especially if single, but how this has changed over time and many other assumptions require empirical study. Furthermore, how to empower women economically in a patriarchal society is unclear, but the literature suggests that masculinity studies may present some answers. The review highlights the methodological challenges associated with conducting gender sensitive research in Afghanistan and the way misunderstood gender relations create further development challenges. Many questions remain about the role of agriculture in Afghanistan livelihoods and how this shapes, and is shaped by, gender relationships. Moreover, what an agenda for women’s empowerment should look like in Afghanistan’s rural farming communities remains unclear from the review. Empowering women in Afghan’s agriculture sector requires considerable experimentation, more data and contextually relevant, carefully designed programs. The review is relevant to development practitioners, researchers and agricultural scientists working in Afghanistan.
