The purpose of this paper is to analyze the literature on Gender and Executives with the purpose of identifying lines on which future research could be directed in order to eradicate gender differences in the decision-making bodies of companies. A bibliometric study has been carried out on the Web of Science collection which, after a series of filters, has given rise to a sample of 144 articles from 1992 to 2018. The units of analysis used were keywords and bibliographic references. With this information bibliometric maps have been created applying the methodology of co-word and co-cite, clustering and visualization techniques. The results suggest that this is an emerging scientific area not yet sufficiently developed, hinting at new research related to topics such as career, gender diversity and performance, gender and leadership, organizational behavior and mobility, gender and ethics. The emergence of the concept of \"glass cliff\" has been detected in the literature analysed as a sign of the risk posed to women by the access to leadership positions.

In this study, spatial distribution and temporal trends of precipitation and its extreme over Nigeria from 1979 – 2013 were analysed using climate indices; in order to assess climate extreme in the country. Daily precipitation data used in this study was obtained from Nigeria Meteorological Agency (NIMET), Lagos. Climate indices developed by the Expert Team on Climate Change Detection and Indices (ETCCDI) for assessing extreme precipitation were adopted in this study. The Sen’s slope estimator and Mann-kendall trend test were employed in data analysis. Results revealed that precipitation and its extremes varied spatially across Nigeria from one geographical location to another. Significant negative trends were observed in most of the precipitation indices for the period under study. Furthermore, significant downward trends were observed in the CWD, while the CDD showed significant upward trends in all the regions. These are indication that the country is trending towards a warmer and drier climate. These could be attributed to global warming-induced climate change, which altered rainfall patterns. The findings of this study explained the extreme events experienced in Nigeria that are generally assumed by many as normal recurrent events. The yearly and decadal changes in precipitation and its extremes as well as for the last 35 years (1979 - 2013) were determined. The changes in precipitation and its extremes observed in this study have severe implications on water resources.

This research aims to determine the pattern of application of the doctrine, worship or rituals (dhikr) are vertical and zakah horizontally as well as its impact on sustainable community economic empowerment as well to improve people\'s living a viable, self-sufficient in the competitive sector of the primary sectors of public life. The method used in this research is qualitative with a phenomenological approach. Researchers plunge spaciousness and objects investigators interviewed. The results of this study point to and that the level of spiritual leadership, doctrine, and remembrance of the Congregation has an impact on its acceptance and utilization as well as gaining sympathy from the local Muslim community which can affect branding, income, entrepreneurship and encourage charismatic traits for this tarekah

In this paper, the morphology and chemical composition of oxide films on the melt surface two commercial purity AlSi7Mg0.3 alloys were investigated by the scanning electron microscopy and EDS analyses. It had been found that morphology and chemical composition of oxide films was different from those in commercial purity aluminium melt due to the effects of alloying elements on the oxidation process and the formation mechanism of the oxidation products. From the thermodynamically view, the preferential oxidation of alloying elements in Al alloys is due to Gibbs Free Energy of Formation for each element. The elements such as Ca, Mg and Sr which have more stable oxide than Al, because of non-protective nature of their oxide films, may increase the oxidation of Al-melts.

The level of knowledge of general service workers of a university in the district of Cartagena de indias was determined about the occupational hazards to which they are exposed daily during their workday. From their perception and observation of the evaluators. A descriptive cross-sectional study was conducted in a population made up of workers in the general services area. A questionnaire was applied that collected information in several dimensions: Socio-demographic data, Labor aspects, academic training and satisfaction with the area where he works. It is evident that both genders are male and female, working in the corporation, being the most numerous vigilantes and neat. The control for the prevention of occupational accidents is based on the participation of general service workers, through knowledge of the risks to which they are exposed, responsibility and personal commitment.

Changes in land cover are evidence of physiological earth processes. The recent study was analyzed the dynamic increase in water area of Rawal lake by using high-resolution Sentinel-2A images for the last four years (2016-2019). High-resolution images (10-meter spatial resolution) provide the easiest way to detect change. Image differencing technique was used to map pixel by pixel change in reflectance values. The land cover change was assessed by using the Iso-cluster algorithm in the Geographic information system (GIS). The results indicated there was increase in the water area from 485 hectares to 556.5 hectares (14 %) due to ecological and hydrological processes. These changes have negative and positive impacts on the ecology of reservoirs and people’s life too. Hence, there is need for proper management, time to time analysis and care of natural reservoirs.
