Forecasting approaches that exploit analogies require the grouping of analogous time series as the first modeling step; however, there has been limited research regarding the suitability of different segmentation approaches. We argue that an appropriate analytical segmentation stage should integrate and trade off different available information sources. In particular, it should consider the actual time series patterns, in addition to the variables that characterize the drivers behind the patterns observed. The simultaneous consideration of both information sources, without prior assumptions regarding the relative importance of each, leads to a multicriteria formulation of the segmentation stage. Here, we demonstrate the impact of such an adjustment to segmentation on the final forecasting accuracy of the cross-sectional multi-state Kalman filter. In particular, we study the relative merits of single and multicriteria segmentation stages for a simulated data set with a range of noise levels. We find that a multicriteria approach consistently achieves a more reliable recovery of the original clusters, and this feeds forward to an improved forecasting accuracy across short forecasting horizons. We then use a US data set on income tax liabilities to verify that this result generalizes to a real-world setting.  相似文献

ABSTRACT

This semi-ethnographic research is an exploration of the creative process from the unique perspective of the circus business. It examines from an interpretivist perspective how circus companies collaborate in the generation and manifestation of ideas, balancing the demands of maintaining a strict physical training regime with devising the circus aesthetic for an expectant audience. The focus of the research is a retired aerial trapeze artist and company director supported by contributions from semi-structured interviews with nine contemporary circus directors and an arts policy officer. Issues were identified from attending three circus network events providing an opportunity to conduct an online questionnaire resulting in thirty-nine responses. Following thematic analysis across all data, key themes emerge identifying networked creativity, productive creativity and intrinsic creativity which correlates to conceptual models of creativity and innovation in organisations. Preliminary findings suggest that networks, skills and intrinsic motivation are integral to creativity within the circus business environment. Whilst this may not be unique to circus, the depth to which it is experienced and its inter-relationality to the form, is readily apparent. This has potential interesting implications for further research within a circus context as well as implications for further exploration of practice in other creative sectors.  相似文献

In the past, corporate sustainability scholars advocated that, for many firms, environmental management could turn into a valuable capability conferring a competitive advantage. However, little attention has been paid to the role of the industry context and its influence on the relationship between environmental management and organizational performance. In this study, we examine the effect on this relationship of three contextual variables: munificence, dynamism and complexity. Drawing on longitudinal data from 336 firms representing 30 industries, we find that munificence enhances the degree to which a firm can leverage its environmental management capabilities to improve environmental performance.

In this article we analyze how privilege is dynamically constructed as well as contested. A positioning analysis of interviews with employees of a multinational organization reveals the construction of a hierarchy of privilege. As this hierarchy is based on English proficiency along with other diversity dimensions, privilege is multifaceted. Furthermore, privilege is also contested. Contesting English-proficiency–related privilege is connected to the speaker's position in the hierarchy of privilege. The analysis shows that both category membership and specific competences and skills cumulate to produce privileging effects, but also the possibilities for contesting privilege. At the same time, although the privilege gained by English proficiency is not invisible and is regularly contested, it is nevertheless silenced by those in advantage.  相似文献

The economic literature focuses mostly on faster ageing of population among developed countries; however, many developing countries experience even more dramatic pace of this process. Mauritius, with the median age of population higher than the world average since 1990s, represents a prominent example of such a case. In this paper, we analyse demographic developments in Mauritius and discuss their macroeconomic implications using an open-economy OLG model with demographic shocks. We project that a decline in the Mauritian interest rate and net foreign assets to GDP resulting from ageing will be accompanied by a temporary increase in GDP, consumption and investment.  相似文献

This article draws on a survey of over 400 employees in two privatised companies. It examines the relationship between the depth of share ownership and social class and prior political orientations, and suggests that employee attitudes are best understood as a function of these standard sociological factors.  相似文献

The repeated play of an asymmetric Battle of the Sexes is analyzed from the perspective of “strategic pattern recognition.” Convergence to equilibrium patterns (in finite histories) and related concepts like breaking-an-equilibrium-pattern are defined and applied to the data. More than half of 202 pairs of subjects are characterized as weakly converging to a fixed equilibrium pattern. The results also show that subjects tend to break their best pattern in cases where their partners' payoffs are relatively low and that convergence initiation does not pay off. While female subjects frequently reject the males' best equilibrium with anonymous matching, behavior gets more cooperative when pairs are introduced to each other before the beginning of the game.  相似文献
