The nutrient distribution of the Cochin Backwater was studied at 6 stations throughout the year. The depth profiles of phosphorus (inorganic and organic), nitrogen (nitrate and nitrite) and silicon, showed a marked seasonal rhythm, induced by the local precipitation and land runoff. Changes in other environmental features such as temperature, salinity, dissolved oxygen, pH and alkalinity were small during the premonsoon period when the system remains marine-dominated, and large during the monsoon period when the estuary becomes freshwater-dominated. Seasonal changes in the hydrographical conditions of the adjoining coastal waters of the Arabian Sea which influence the backwater system have been discussed. 相似文献
Traditionally, firms tend to incline toward financial performance and profitability to surge shareholder's wealth. In the modern day, in addition to financial performance, innovative and environmental performance has also become a central effort. However, all firms are not flourished in the achievement of financial, innovative, and environmental performance, particularly small‐ and medium‐sized enterprises (SMEs), which need adequate financial resources due to lack of resources and can search for opportunities to boost their performance. This research examines the role of financial availability in financial, innovative, and environmental performance with a mediating role of opportunity recognition. Empirical evidence is collected through structured questionnaires from 347 SMEs operating in the emerging market Pakistan. Hypotheses are tested in Analysis of a Moment Structure (AMOS) using structural equation modeling. Results indicate that satisfactory financial resources significantly contribute to financial and innovative performance but play an insignificant role in environmental performance as well. In addition, firms with enough financial capital recognize new opportunities significantly via opportunity recognition mediator, where partially mediating the relation between financial availability and financial/innovative performance. However, firms fully mediate the link between financial availability and environmental performance. Our research findings recommend CEOs and top managers to utilize their financial resources in an efficient way to achieve the advantage of the new opportunity recognition, superior financial, innovative, and environmental performance. 相似文献

District Swat is part of the high mountain Hindu-Kush Himalayan region of Pakistan. Documentation and analysis of land use change in this region is challenging due to very disparate accounts of the state of forest resources and limited accessible data. Such analysis is, however, important due to concerns over the degradation of forest land leading to deterioration of the protection of water catchments and exposure of highly erodible soils. Furthermore, the area is identified as hotspot for biodiversity loss. The aim of this paper is to identify geophysical and geographical factors related to land use change and model how these relationships vary across the district. For three selected zones across the elevation gradient of the district, we analyse land use change by studying land use maps for the years 1968, 1990 and 2007. In the high-altitude zone, the forest area decreased by 30.5 %, a third of which was caused by agricultural expansion. In the mid-elevation zone, agriculture expanded by 70.3 % and forests decreased by 49.7 %. In the lower altitudes, agriculture expansion was 129.9 % consuming 31.7 % of the forest area over the forty-year time period. Annual deforestation rates observed were 0.80, 1.28 and 1.86 % in high, mid and low altitudes, respectively. In the high-altitude ecosystems, accessibility (distance to nearest road and city) had no significant role in agriculture expansion; rather land use change appears significantly related to geophysical factors such as slope, aspect and altitude. In the low-elevation zone, accessibility was the factor showing the closest association with agriculture expansion and abandonment. The analysis illustrates that land use change processes vary quite considerably between different altitudinal and vegetation cover zones of the same district and that environmental constraints and stage of economic development provide important contextual information. 相似文献
This research aims to investigate the impact of social networking, family support, social dominance orientation and, access to finance on the entrepreneurial intention among Omani women and to examine the mediating role of entrepreneurial persistence and entrepreneurial passion between growth constraints and the entrepreneurial intention on Omani women. The contribution of women in the development of the economy has received great attention in the past years. Therefore, to motivate women to engage in entrepreneurship, it is necessary to understand the growth impediments that impact their entrepreneurial intentions to achieve sustainable development goal (SDG-5). By using the stratified sampling method, this study collected data from 262 Omani women from nine regions, including Al Batinah North, Al Batinah South, AlBuraimi, Muscat, Ash Sharqiyah South, Ad Dakhiliyah, Dhofar, Ad Dhahirah, and Musandam. The study's findings showed that social networking significantly impacts entrepreneurial intention and entrepreneurial persistence. At the same time, access to finance and family support has an insignificant effect on entrepreneurial persistence, entrepreneurial passion, and entrepreneurial intention. The findings indicate the role of the mediating variables between growth constraints and entrepreneurial intention. Based on findings that offer valuable insight, several recommended strategies are provided for policymakers in general and for the socio-economic development of Omani women, in particular. 相似文献
This article explores the influence of corporate social responsibility (CSR) and three green triggers of environment (awareness, concern, and knowledge) on employee well‐being and green behavior. The study engages the stimulus–organism–response model for testing the association between CSR and well‐being of employees that leads to employee green behavior. Furthermore, social exchange theory has been utilized to describe the association between well‐being and green behavior of employees. Data have been gathered through questionnaire from 509 employees working in guest‐service hotels of Pakistan. Structural equation modeling has been used to test the hypotheses. Findings show that CSR, environmental concern, and knowledge have positive effect on employee well‐being, whereas environmental awareness has positive but insignificant effect on employee well‐being. Furthermore, environmental concern, knowledge, and well‐being have a positive influence on green behavior, whereas CSR and environmental knowledge have a positive but insignificant effect. Moreover, well‐being fully mediates the relationship between CSR and green behavior and between environmental awareness and green behavior of employees. However, a partial mediation was observed between environmental concern and green behavior. The findings also indicate that no mediation was found between environmental knowledge and employee green behavior. The findings suggest that the hotel managers should invest to improve employee's awareness regarding green behavior by conducting environmental training for cultivating environmental knowledge and awareness. Moreover, CSR activities should be performed for attaining competitive edge and maintaining a balance between progress and sustainability of environment. 相似文献
Economic policy uncertainty generally tends to induce a pessimistic view of future market behaviour. Furthermore, instabilities in global oil prices have serious implications for the economies of oil exporters and importers, due to their over-dependence on crude oil for revenue and production activities, respectively, and thereby on stock market indices. Against limited empirical evidence, this study examines the spillover effects from global economic policy uncertainty (GEPU) and oil price volatility to the volatility of the stock market indices of oil exporters and importers in both developed and emerging economies. The results show that the spillover effect from GEPU to oil exporters is relatively smaller than to oil importers, for both developed and emerging countries. Conversely, the volatility spillovers from oil prices to oil exporters are relatively larger than to oil importers, for both developed and emerging countries. Specifically, the volatility spillovers from oil prices to oil exporters (importers) in emerging countries are relatively stronger compared to oil exporters (importers) in developed countries. The findings indicate that the volatility of the stock markets of emerging countries is more sensitive to global factors such as GEPU and oil price volatility, and that oil exporters and importers in emerging economies are more sensitive to oil price volatility than oil exporters and importers in developed economies, which is in line with previous studies.
