This study shows how Guttman errors analysis can be applied to social research. In this work, the method is used in the study of environmental concern. The new instrument usefully chart also ways in which less evident forms of engagements may be recognized. The study uses data from the 2000 World Values Survey and International Social Survey Programme. First, Mokken Scale Analysis is applied to build a cumulative scale of mobilization for the defense of the environment. Second, Guttman errors are analyzed to identify specific patterns of activism. The analysis of the indexes enable the isolation of an often elusive phenomenon not shown by other techniques: the presence of individuals with a pronounced degree of activism but who do not share the attitudes of the majority of environmentalists. These particular patterns might constitute specific ways to relate to the environment. Guttman errors analysis can be fruitfully applied in measurement of attitudes or behavior. In particular, it can shed light on the presence of individual that sociological research should consider, study and label separately.  相似文献

This article studies the interrelation among the volumes of bonds and stocks issued by non-financial firms, and levels of industrial loans outstanding in the United States. These aggregates are co-integrated and characterized by asymmetric volatility. Their co-movements are driven by financial indicators such as the yield spread, size of loan market and market volatility. Bond and stock issuance are positively correlated, and even more so during the expansionary phase of the cycle. Loans outstanding and bond issuance are negatively correlated, and their substitutability increases in periods of economic downturn, highlighting the importance of bond markets to mitigate credit crunches.  相似文献

The present paper investigates the relationship between the involvement of family firms in R&D collaborations aimed at developing green solutions and the value of resulting innovations. To dig into this relationship, the moderating effects of two proximity dimensions (i.e., geographical distance and technological relatedness) are also assessed. Analyses are based on a sample of 156 joint patents classified into the “Alternative energy production” field, as defined by the International Patent Classification Green Inventory and successfully filed at the United States Patent and Trademark Office in the period 1997–2010 by publicly listed companies. According to our conjectures, results reveal a positive relationship between the involvement of family firms and green innovation value. Moreover, our findings show that this relationship is hindered when partners are geographically distant or technologically proximate. Eventually, we contribute to the literature on green innovation by unveiling under which conditions inter‐firm R&D collaborations lead to more valuable innovations.  相似文献

This paper analyses the growth effects of capital formation, exports and FDI as major, drivers of economic development in Eastern Europe. The fundamental innovations are, identified by empirically and theoretically motivated short- and long-run restrictions in, structural cointegrated vector autoregressions. Impulse responses and variance, decompositions reveal quite different growth effects in various Eastern European countries. Generally, a strong reliance on exports goes along with higher GDP, and FDI bears, substantial potential for fostering economic growth. It is shown that the recent worldwide, recession clearly hit Eastern Europe through the export channel, whereas the recovery is, mainly supported by positive demand shocks.  相似文献

Despite significant academic and managerial interest in big data, there is a dearth of research on how big data impacts the long‐term firm performance. Reasons for this gap include a lack of objective indices to measure big data availability and its impact, and the tendency of studies to ignore the costs associated with collecting and analyzing big data, assuming that big data automatically delivers benefits to firms. Focusing on how firms create and capture value from big data about customers, we use the resource‐based view and three dimensions of big data (i.e., volume, variety, and veracity) to understand when the benefits outweigh the costs. Relying on the number of downloads of mobile device applications, we find that volume of big data has a negative effect on firm performance. This result suggests that the “bigness” of big data alone does not ensure value creation for a firm, and could even constitute a “dark side” of big data. Because big data variety—measured as the number of types of information taken per each application—moderates the negative effects of big data volume, simultaneous high values of volume and variety allow firms to create value that positively affects their performance. In addition, high levels of veracity (i.e., a high percentage of employees devoted to big data analysis), are linked to firms benefiting from big data via value capture. These findings shed light on the circumstances in which big data can be beneficial for firms, contributing to a better theoretical understanding of the opportunities and challenges and providing useful indications to managers.  相似文献

La relation entre i'état et le développement social peut entre analysée à partir de trois niveaux interconnectés:
  • 1 Au niveau de la théorie et de la méthodologie. C'est ce que font Lojkine et Pahl.
  • 2 A un niveau général, mais concernant des types théoriquement differenciés d'organisations sociales (c'est à dire, sociétés capitalistes avancées, sociététés socialistes. etc.). C'est le niveau qui concerne cet auteur le plus.
  • 3 Au niveau d'une société donnée, durant une période historique déterminéee. C'est à ce niveau que les autres travaux de Lojkine ont été faits.
La critique faite par Pahl des perspectives marxistes est rejetés comme étant superficielle, par contre il est reconnu que i'?uvre de Poulantzas manque de perspective historique et dialectique. Mais i'analyse marxiste des institutions politiques dépend d'une interprétation correcte de la relation entre structure et superstructure, et ce point est développé par i'auteur. Une critique est faite des théories élitistes et historicistes. La typologie historiciste de Runciman est considérée comme étant inadéquate, car elle ne peut ětre appliquée à la réalité historique, et en dernier lieu, ne peut expliquer pourquoi les relations état-société montrent tant de variations. Les définitions marxistes de i'état sont insuffisantes et ont besoin d'ětre dévéloppées. A propos, les travaux de Lojkine et de Poulantzas sont critiqués comme étant réductivistes et non-dialectiques. La question des origines sociales de la démocratie est introduite afin de développer une perspective analytique satisfaisante qui pourrait prendre en compte les faits historiques des révolutions nationales en Europe de l'Ouest, au Japon et aux Etats-Unis. L'accent est mis sur le role de la classe ouvrière, le concept d'hégémonie, l'exercise du pouvoir hégémonique, et plus précisement quand la classe hégémonique n'est pas dominante. Une bonne analyse marxiste des relations état-société doit pouvoir envisager les tendences et les conditions actuelles de l'accumulation du capital, en conjonction avec les intérěts des groupes monopolistes. Cet essai fini par une brěve discussion des tendences actuelles dans ces domaines.  相似文献
