What does it all mean? We've reviewed five studies involving almost 2,000 people compared on a total of 43 scales. We've studied matched pairs and controlled for level of managerial achievement. And after all is said and done, we have detected a total of two overall differences between male and female managers. One of these, involving managerial work motivation, favors females: Their work motivation profiles are more “achieving” than those of their male counter-parts. The other difference, pertaining to interpersonal competence, favors the male managers: They are more open and candid with their colleagues than are females. Add to these the more titillating than significant anomalies of differing back-up style preferences and we are left with one conclusion: Women, in general, do not differ from men, in general, in the ways in which they administer the management process.Managers themselves and their subordinates concur. It seems that the disproportionately low numbers of women in management can no longer be explained away by the contention that women practice a different brand of management from that practiced by men. Whereas this may amount to good news in some quarters, we ought not be prematurely elated by discovering that women manage just the way men do. Carolyn Sherif has pointedly called attention to the fact that all is not necessarily well in today's male-oriented management activities.We of course view management in its more global aspects: The important issue to us is how an individual manages in relation to achievement criteria. Individual achievement and organizational health ultimately depend on the way management is practiced. And we now see that the way management is practiced is not related to the sex of the manager — the issue is generic rather than gender-bound.  相似文献

Using a sample of workers and managers employed by a hotel located in Southeastern People’s Republic of China, we investigated the relationship between various human resource management practices and the perceived organizational support (POS) experienced by the employees. We then investigated the effects of POS on employee satisfaction. Our data suggest that hiring practices, training, and compensation practices predict POS. These results are consistent with previous research. We also found that POS influences worker satisfaction and acts as a mediator between select HR practices and satisfaction. This study contributes to the literature by replicating Western-based findings with a Chinese sample and illustrating that the attitudes of Chinese employees can be influenced through the use of HR practices.  相似文献

The paper investigates whether business cycle variables and behavioural biases can explain the profitability of momentum trading in three major European markets. Unlike previous studies, the paper nests both risk-based and behavioural-based variables in a two-stage model specification in an attempt to explain momentum profits. The findings show that, although momentum profitability in European markets is unexplained by conditional asset pricing models, it is attributable to asset mispricing that systematically varies with global business conditions. In addition, behavioural variables do not appear to matter much. Thus risk factors, which are undetected thus far and are largely attributable to the business cycle, could explain the momentum payoffs in European stock markets.  相似文献

Although biodiesel is considered a safe substance for the environment, its production can be dangerous because it involves flammable and toxic substances, such as methanol. In addition to the risks associated with fire and explosions, methanol also implies a risk to the health of workers who are constantly inhaling this product, even in low concentrations. Despite all the associated risks, most Brazilian industries produce biodiesel from methanol. Aiming to find an alternative to make the production process of biodiesel safer, several research studies were carried out in which the advantages and disadvantages of methanol substitution for ethanol were raised. From there, it was found that the biggest advantage is actually making the production process safer. However, it has been found that this proposal is still not feasible because the production of biodiesel by an ethyl route raises the cost of production considerably. In view of the foregoing, it was concluded that the alternative presented is only feasible through measures that compensate for the increase in costs, such as fiscal incentives.  相似文献

This paper integrates the theory of demand for publicly provided goods in a democracy with the theory of bureaucratic supply in order to develop a model of benefit share and tax share discrimination by a monopoly bureau. The demand side of the political market is based on a utility maximizing model of voter behavior with voters' demands aggregated through a majority voting process. The supply side of the political market is based on a budget maximizing model of bureaucratic behavior. The bureau is assumed to possess monopoly power as a result of either its control over benefit shares or tax shares and, hence, implicit tax prices or its control over budget proposals placed on the agenda. Different degrees of discrimination are examined and in each case the equilibrium of the model yields a total budget for the bureau as well as distributions of benefit shares or tax shares across voters.  相似文献

Conditional probability distributions seem to have a bad reputation when it comes to rigorous treatment of conditioning. Technical arguments are published as manipulations of Radon–Nikodym derivatives, although we all secretly perform heuristic calculations using elementary definitions of conditional probabilities. In print, measurability and averaging properties substitute for intuitive ideas about random variables behaving like constants given particular conditioning information.
One way to engage in rigorous, guilt-free manipulation of conditional distributions is to treat them as disintegrating measures—families of probability measures concentrating on the level sets of a conditioning statistic. In this paper we present a little theory and a range of examples—from EM algorithms and the Neyman factorization, through Bayes theory and marginalization paradoxes—to suggest that disintegrations have both intuitive appeal and the rigor needed for many problems in mathematical statistics.  相似文献

This paper examines the effect of financial inclusion on women's empowerment. We contribute to the growing interest in financial inclusion effectiveness literature by conducting an empirical analysis of 42 African countries to examine the role of financial inclusion in empowering women. We also examine and compare the effectiveness of the three dimensions of financial inclusion viz. usage, access, and quality, and the first most influential indicators, based on their PCA score, of these dimensions. Our findings suggest that financial inclusion has a significantly positive effect on women's empowerment-measured by females' human development index. Examining the relative importance of financial inclusion dimensions, we find access to financial services has a higher effect on women's empowerment. These results are robust to alternative measures of women's empowerment and financial inclusion, and alternative estimation procedures. We also find that the effect of financial inclusion on women's empowerment is higher in low and lower-middle-income countries compared with upper-middle-income countries in the region. This study provides evidence of one of the channels through which financial inclusion contributes to reducing gender inequality, and thereby enhancing economic development.  相似文献

Pressure continues to build on the operations management function to facilitate system and firm level benefits. In the online marketplace, one area of growing interest is that of product returns. Though commonly viewed as a cost center from an operations perspective, operations’ actions have the potential to strongly influence future customer buying behavior in several ways. Using an archival database of actual purchase and returns history provided by a moderately sized online retailer, this study examines the relationship between a customer's experience of product returns, and subsequent shopping behavior. Employing transaction cost, consumer risk, and procedural justice theories, we demonstrate that the returns management process, rather than being regarded as an afterthought to the production and deployment of goods, can significantly and positively influence repurchase behavior. Additionally, we provide evidence that certain customers should be considered for prioritization in the returns process. We suggest ways through which operations managers can take care in discharging their responsibilities in this area – to make returns processing more than simply a “necessary cost of doing business” rather, using it to their advantage in engendering repeat and increased purchase behavior.  相似文献

We extend the Tobit (censored) linear equation system procedure to utility‐theoretic demand functions, along with a mapping mechanism to impose the adding‐up restriction implied by consumer utility maximization theory—a theoretical restriction very often ignored in previous empirical studies with censored demand systems. In this context, the Bayesian Markov Chain Monte Carlo (MCMC) procedure is applied to the censored linear approximate almost ideal demand system (LAIDS) for 12 food products, using data from the Turkish Household Expenditure Survey. All own‐price elasticities are negative and expenditure elasticities positive. Uncompensated own‐price elasticities for rural households are generally much higher than those for their urban peers, though demand for most food products are own‐price elastic for both types of households. The differential patterns in demand elasticities between urban and rural households become even more evident (almost twice) as relatively more expensive foodstuffs are consumed, showing that accessibilities to alternative products have made rural Turkish households more cognizant toward price changes in foods. Household characteristics play a key role in food expenditures, notably so in urban areas, and regional and seasonal differences are also present.  相似文献
