Viene considerato il problema della determinazione della «politica ottima» di un'impresa che deve ammortizzare un prestito diviso in obbligazioni, noti i tassi di interesse del prestito, la redditività del capitale disponibile e prefissati vincoli sul numero massimo di obbligazioni da rimborsare nei singoli anni. Il problema viene risolto coi metodi della programmazione lineare. 相似文献

This paper empirically evaluates the uncertainty of forecasts. It does so using the 1001 series of the M-Competition. The study indicates that although, in model fitting the percentage of observations outside the confidence intervals is close to that postulated theoretically, this is not true for forecasting. In the latter case the percentage of observations outside the confidence intervals is much higher than that postulated theoretically. This is so for the great majority of series, forecasting horizonts, and methods. In addition to evaluating the extent of uncertainty, we provide tables to help users to construct more realistic confidence intervals for their forecasts. 相似文献

Ethics in accounting and ethical education have seen an increase in interest in the last decade. However, despite the renewed interest some important shortcomings persist. Generally, rules, principles, values and virtues are presented in a fragmented fashion. In addition, only a few authors consider the role of the accountants character in presenting relevant and truthful information in financial reporting and the importance of practical reasoning in accounting. This article holds that rules, values and virtues are interconnected. This provides a sound approach to ethics in accounting, in which character and practical reasoning are crucial. Consequently, ethical education in accounting has to simultaneously include the knowledge of proper rules and principles and their correct application; values (understood as moral goods) and virtues, whose acquisition, in the view of the author, should be encouraged. 相似文献

ABSTRACT The authors examine the use of mobile money in the context of cross-border remittances in West Africa. Relying on mixed methods and a multi-sited empirical strategy they look at both the sending and receiving conditions of mobile money transfers. By looking at money as socially embedded and the role of migrants in the production of a transnational space, their results highlight that uptake and usage of mobile money for remittances are shaped by a transnational living pattern. At the same time, mobile money also contributes to strengthening and reshaping this pattern. By showing that conversion of virtual money to cash may be performed by brokers that live far away from the end recipient, the paper highlights an important gap between spatial distribution of mobile money infrastructure and the social mediation that supports e-money flows. Cash-based transactions, in turn, are shown to play a key role in the social mediation dynamic. 相似文献

ABSTRACTFor media planners to combine multiple media across platforms to maximize synergy is a critical challenge within integrated marketing communication. For this study, in-depth interviews were conducted with experienced media specialists in leading agencies to explore how they integrate different out-of-home advertising media platforms in IMC strategies. The feedback of these experts was then used to propose a model of strategies to enhance synergy within out-of-home advertising campaigns. This model is a first of its kind for planning out-of-home advertising media across platforms and bridges a gap in the existing literature on media synergy and out-of-home advertising media strategy. 相似文献

Trade secret theft is a problem that almost all organizations face. The greatest threat is employee mobility and potential unethical post‐employment behavior. This study investigates the role of individual personality traits in judgments about trade secret misappropriation. Our hypotheses were tested in three studies addressing three different situational contexts: current employees, employees about to be laid off, and students who had quit their job. Relationships were estimated with robust regression. The results show that some personality traits predict judgment about another person's trade secret misappropriation, and that the situational context in which individuals formulate their ethical judgment moderates the impact of personality traits on ethical judgment. 相似文献

ABSTRACT Antoine Hennion is a Professor of Sociology at the Centre de Sociologie de l’Innovation (Mines-Paris Tech, PSL/CNRS). He has been researching taste and cultural practices through a pragmatic lens for three decades. He has developed an original and impactful theoretical framework bridging the Actor-Network Theory to Cultural Studies. More precisely, he reconceptualized the notions of mediation and attachment. Antoine Hennion has explored various empirical settings, including music, wine, and sports. More recently, he has contributed to a large research project on migration. His books and academic articles have had an impact on Sociology, and are getting greater attention in consumer research. 相似文献
