In Mexico, there are more and more women running various organizations, including those belonging to the field of education, and universities are no exception. On the other hand, the type of leadership being exercised can promote or hinder the proper performance of the institute and may be a factor of distinction and influence the behavior of those who integrate it; therefore, knowing how it works provides feedback about the processes that determine organizational behavior and the working environment.展开更多

This study aims to give detailed descriptions on characteristic patterns of maternal rank acquisition from infant to juvenile. Focal subjects were 22 young monkeys belonging to three cohorts born in 2002, 2003 and 2005. Data were collected with a total 2130 sessions of 30-minute continuous recording of focal subjects combined with all occurrence-sampling methods. The onset of aggressive behavior varied per cohort and was delayed in cohorts with fewer close-aged associates. More than 60% of dyadic combinations in agonistic interactions between peers were unidirectional throughout the study period. Although some bidirectional interactions could have involved unstable relationships between particular individuals, most of the bidirectional interactions included a few continuous series of alternating one-sided interactions. A linear order could be found among peers from the first appearance of aggressive behavior, and nearly 90% of those dyads were concordant with that of their mother＇s rank order. Young males were responsible for most of the dominance relations that would not be predicted based on their mother＇s rank. These results suggest that infant monkeys may recognize their own social status relative to their opponent＇s before onset of aggressive behavior and adjust themselves into the matrilineal rank system accordingly.展开更多

To achieve the objectives of the study, we collected data from all 15 banks listed on the Amman Stock Exchange for the year ending December 2013. The findings of the study suggest that there is strong compliance with respect to mandatory risk disclosure, as required by IFRS. However, the results generally signal a need for further improvement in the voluntary risk disclosure area, since most of the banks do not provide adequate information that can be of use to stakeholders. We also suggest future avenues of research into the topic to determine progress.展开更多

Using 142 firms listed in the Shenzhen Stock Exchange （SZSE）, which was collected from the Guotaian Research Service Center （GTA-RSC） databases, this study uses two proxies to measure firm performance and three proxies to measure managerial entrenchment. The two proxies for firm performance are Tobins＇ Q and return on assets （ROA）, and the three proxies for managerial entrenchment are entrenchment 1, entrenchment 2, and entrenchment 3. These three entrenchment proxies are derived from the principal component analysis （PCA）. Though previous studies of managerial entrenchment and firm performance variables suffer from endogeneity, with respect to the corporate governance it is unclear as to which variables are endogenous and which are exogenous. This study confirms that the data are linear and no endogeneity issue should be address in this study, but only heteroskedasticity, non-normality for Tobins＇ Q are a problem, therefore, the regression method employed for Tobins＇ Q is the generalised least square （GLS） and the ordinary least square （OLS） between estimators for ROA. The regression result for Tobins＇ Q reveals that managerial entrenchment is negatively impact on firm performance. The results are in contradiction to the stewardship theory for new firms whereas the managerial entrenchment for new firms is positive. Furthermore, only one entrenchment proxy yields a significant coefficient. In conclusion, the negative results of entrenchment proxies were caused by the different institutional structures and legal systems which are the Chinese corporations that are still largely owned and controlled by a state and hence the centralised state controlled was responsible for all managerial actions.展开更多

Seabirds need to both reach profitable areas, which can be located far from the colony, and return to the colony regularly. In this context, flexibility in movement behavior may be crucial for breeding success. During chick-rearing, Procellariformes species can alternate short trips lasting 1-4 days for chick provisioning with longer trips for self-provisioning in what has been called a dual-foraging strategy. We analyzed foraging trips from 136 Scopoli＇s shearwaters from three Mediterranean colonies tracked with GPS during 6 chick-rearing seasons to assess whether the adoption of a dual fo- raging strategy depends on the quality of habitat surrounding the colony. We found a marked dual-foraging strategy only in birds from the Linosa colony which was the largest colony in terms of breeding pairs and was characterized by having a lower marine habitat quality. Birds from this colony performed foraging trips that extended up to 369 km from the nest and lasted more than 10 days. In general, the decision to perform long lasting trips was triggered by lower values of primary production and higher offspring weight. Contrary to expectation, the decision to feed far from the colony was not related to the parents＇ weight. At the same time, despite the higher productivity offered by distant areas, the higher proportion of long trips performed by birds breeding in poor areas was not sufficient to maintain the same body mass as the ones breeding in richer areas [Current Zoology 60 （5）： 622-630, 2014].展开更多

It is given by a kinetic/Fokker-Planck-type equation whose coefficients depend on the shear rate of the experiment. In this paper we want to study what happens to the stationary solutions of this model when the shear rate is asymptotically large. In order to do that, we expand the solution of the equation using singular perturbation tools. In the end, we rigorously prove the estimate of Hebraud and Lequeux that the material asymptotically behaves as a Newtonian fluid.展开更多

文摘The H@braud-Lequeux model is a model describing the flow of soft glassy material in a simple shear flow configuration. It is given by a kinetic/Fokker-Planck-type equation whose coefficients depend on the shear rate of the experiment. In this paper we want to study what happens to the stationary solutions of this model when the shear rate is asymptotically large. In order to do that, we expand the solution of the equation using singular perturbation tools. In the end, we rigorously prove the estimate of Hebraud and Lequeux that the material asymptotically behaves as a Newtonian fluid.
