基于多时相HJ卫星的渭干河-库车河绿洲主要农作物种植信息提取

在3S技术的支持下全面、快速、客观地监测农作物种植信息,对于正确的把握该区域的农业结构和布局,进行作物种植空间格局的调整和优化有着十分重要的意义.本文以渭干河-库车河洲绿洲为研究区,根据农作物的物候规律和季相节律的差异性特点,选取2012年的3景不同时相的HJ卫星CCD遥感数据,ENVI下基于CART算法的决策树规则自动提取主要农作物覆盖信息,然后以野外GPS调查点为依据,对决策树方法预分类结果进行修正,成功提取了研究区的玉米、棉花和小麦的种植面积,总体精度达到了91.73％.结果表明HJ卫星CCD影像可以很好地应用于农作物提取,而且CART算法的分类精度较高,能较好地反映作物的分布状况,可为该地区主要作物种植结构调整提供一定的依据.     

International Export Orientation and Firm’s Performance: Evidence from Enterprise Survey Data of India

This study aims at analyzing the performance of firms by international export orientation vis-à-vis domestic orientation, based on World Enterprise Survey Data of 9,281 firms of India. Simple statistical techniques such as chi-squared test, ANOVA, and regression model have been used to analyze the data with the help of SPSS version 20.0. Chi-square statistics indicate that there is significant difference in enterprise characteristics by business orientationdomestic versus export-oriented businesses. Result of the ANOVA indicates a significant difference in business performance between export versus domestic orientation of firms in terms of sales and employment growth rates. Export-oriented enterprises perceive comparatively fewer obstacles than domestic enterprises. Regression analysis indicates that enterprise characteristics, performance indicators, and business obstacles have influence on export orientation of the firms. This study provides insights on differences in firms’ performance across business orientations and factors affecting the internationalization of business. This study can be helpful in designing policies for promoting export-oriented enterprises in a focused manner.     

Higher Ethical Objective (Maqasid al-Shari’ah) Augmented Framework for Islamic Banks: Assessing Ethical Performance and Exploring Its Determinants

This study utilises higher objectives postulated in Islamic moral economy or the maqasid al-Shari’ah theoretical framework’s novel approach in evaluating the ethical, social, environmental and financial performance of Islamic banks. Maqasid al-Shari’ah is interpreted as achieving social good as a consequence in addition to well-being and, hence, it goes beyond traditional (voluntary) social responsibility. This study also explores the major determinants that affect maqasid performance as expressed through disclosure analysis. By expanding the traditional maqasid al-Shari’ah,, we develop a comprehensive evaluation framework in the form of a maqasid index, which is subjected to a rigorous disclosure analysis. Furthermore, in identifying the main determinants of the maqasid disclosure performance, panel data analysis is used by including several key variables alongside political and socio-economic environment, ownership structures, and corporate and Shari’ah governance-related factors. The sample includes 33 full-fledged Islamic banks from 12 countries for the period of 2008–2016. The findings show that although during the nine-year period the disclosure of maqasid performance of the sampled Islamic banks has improved, this is still short of ‘best practices’. Through panel data analysis, this study finds that the Muslim population indicator, CEO duality, Shari’ah governance, and leverage variables positively impact the disclosure of maqasid performance. However, the effect of GDP, financial development and human development index of the country, its political and civil rights, institutional ownership, and a higher share of independent directors have an overall negative impact on the maqasid performance. The findings reported in this study identify complex and multi-faceted relations between external market realities, corporate and Shari’ah governance mechanisms, and maqasid performance.

     

Resource Accounting and Executive Agencies

Executive agencies have had several years' experience of the introduction and development of accruals based accounting systems. Senior agency managers therefore provide an authoritative source of information on the problems that could follow from introducing it more widely across government. A survey of senior managers revealed that, despite major improvements in accounting information systems, agencies still face difficulties in implementing accruals accounting. Government departments also seem unlikely to accept easily the switch from cash accounting to accruals accounting without extensive training. The effort and resources required for this should not be underestimated.     

Intercompany mobbing: the effects of company growth

Exploring the concept of mobbing, we have conducted a study of small and middle sized enterprises (commonly referred to as SMSE). In this study we observed corporate policies of repression and intimidation while taking into consideration the aim of these policies and their possible consequences. The ultimate purpose of this work is to shed light onto forthcoming academic studies of the same topic. Our focus has been the effects of the various presses, forms of harassment and market entry prevention carried out by companies that dominate the market against those companies entering the market and those already competing in the market. To determine these effects on 150 companies that conduct business in Turkey, we created a survey consisting of 15 categories. The results have been depicted with charts and graphs. The conclusion of the investigation has found that many of the attitudes which comprise of mobbing acts can be seen in the mutual behavior of the companies that work in the Turkish labor market. Although there are a number of reasons for the prevalence of the mobbing culture in Turkish business, it’s our belief that the Turkish labor market codes of conduct and regulations influence the perpetuation of ruthless behaviors between different companies.

Work–family conflicts and job attitudes of single women: a developing country perspective

This study addresses work–family conflicts and job attitudes of white-collar single women and the ensuing work-related attitudes in a developing country context. After an overview of gender roles in Arab society, several hypotheses were advanced and tested. Although married females reported higher family–work conflicts than single females, the latter group faced a host of strains, which are presented and analyzed. Despite being educated, single females were underpaid and their upward mobility seemed to be significantly hampered. They reported lower job satisfactions and had high intentions to leave their organization. Implications for further research and practice are discussed.
