我国企业信息化建设中的三类角色

本文着重阐述了我国企业信息化建设中的三类角色，它们分别是企业、管理咨询公司和信息化产品开发商。企业信息化是企业、管理咨询公司、信息化产品开发商三方参与，并且互相影响、互相制约、互相促进的全员工程，缺少了三类角色中的任何一方，企业信息化的项目就无法顺利的进行下去。如何处理三者之间的关系，更显得尤为重要。

基于DMSP/OLS数据的中国碳排放时空模拟与分异格局

精准模拟和精细尺度获取碳排放的时空动态信息，对于合理制定差别化的区域碳减排政策具有重要意义.利用DMSP/OLS夜间灯光数据在完成年内和跨年数据的校正、像元去饱和、异常值剔除的基础上，提取了城市建成区范围，并以中国大陆为研究对象，根据夜间灯光数据和碳排放统计数据之间的定量关联，构建面板数据模型模拟了2000~2013年中国的碳排放量；采用Theil-Sen Median趋势分析方法与Mann-Kendall检验，探讨了14年间中国碳排放量的时空变化趋势及空间分布特征.结果表明：系统校正后的DMSP/OLS夜间灯光影像构建面板模型模拟的碳排放量拟合精度较高，2002，2007和2012年多尺度回归检验的决定系数R²值分别为0.893，0.955和0.951.2000~2013年中国碳排放时空演化差异显著，稳慢增长型和迅猛增长型分别占碳排放区域总面积的77.6%和19.4%，稳慢增长型面域宽广，迅猛增长型主要位于都市区及都市连绵区.受城市规模及城市化发育程度的影响，迅猛增长型空间结构呈"空心型"与"中心型"空间指向性分异.研究提出，促进经济增长方式和发展模式的实质性转变、因地制宜差别化的减排措施与省区联动策略的实施是"精准减排"目标实现的重要途径.

Using a pattern‐oriented approach to study leaders: Implications for burnout and perceived role demand

Using a pattern‐oriented approach, we identified clusters of leaders who shared theoretically meaningful combinations of transformational, contingent reward, management by exception active, management by exception passive, and laissez‐faire leadership styles. Drawing upon conservation of resources theory, we examined whether leaders who shared a similar pattern of leadership styles differed from leaders who belonged to other profile groups, with respect to felt burnout and perceived role demands. Hypotheses were tested using a time‐lagged field study involving 183 leaders. Using latent profile analyses, we found four theoretically interpretable patterns. Leaders who belonged to the comprehensive cluster (elevated scores on the transformational, contingent reward, and the passive styles; 14.2%) experienced the highest levels of burnout and role demands, whereas those who were disengaged (low scores on all styles; 33.3%) reported the lowest levels. Leaders who exhibited a passive behavioral pattern (elevated scores on management by exception active, management by exception passive, and laissez‐faire relative to the other styles; 27.3%) experienced more burnout and role demands than did leaders who exhibited an optimal pattern (elevated scores on transformational and contingent reward styles relative to the passive styles; 25.1%). The theoretical and practical implications of a pattern‐oriented approach to leadership research were discussed. Copyright © 2017 John Wiley & Sons, Ltd.     

Spatial Pattern Analysis of Regional Water Use Profile Based on the Gini Coefficient and Location Quotient

Water resources have become a barrier hampering socioeconomic development. Changes in the spatial distribution of water use profile have direct impacts to regional water use efficiency. However, the related research is inadequate, and a more suitable way to analyze regional water use profile is necessary. The Gini coefficient and location quotient, two reliable methods commonly used in discussing the spatial distribution of elements, were introduced and calculated. Taking Gansu Province as the study area, the concentration effect of industrial water use was the strongest, followed by domestic, environmental, and agricultural water use. However, a balanced distribution of agricultural water use failed to be coordinated with the production conditions, the center of Gansu’s grain production should be established to enhance the scale effect of agricultural production. The industrial agglomeration effect remained weak, and each region’s dominant industries need to be developed vigorously. Gansu’s domestic water use was consistent with its population distribution, but it is necessary to reduce the water use gap between urban and rural areas. With a growing awareness of environmental protection, environmental water use exhibited a more balanced distribution. Overall, the methods are simple and have good applicability, and the results can provide a reference in water use optimization.     

碳排放约束下的农业生产效率及其空间格局——基于河南省65个村庄的调查

基于村庄尺度探索碳排放约束下的农业生产效率,对于差别化的低碳农业生产模式的选择具有一定的理论和实践意义。基于河南省65个村庄的调查数据,对不同样点的农业碳排放进行了核算,并采用Super-SBM模型分析了碳排放约束下的农业生产效率的差异。结果表明：河南省农业碳排放强度呈现“南北高,中间低”的空间分布格局,这主要受种植结构、农业生产条件、人类各项投入等因素的影响;碳排放约束下的河南省农业生产效率具有较大的空间差异,根据农业生产效率和碳排放强度的关系,可将样点村庄分为低碳高效村、高碳低效村、高碳高效村和低碳低效村四种类型。其中高碳低效村和低碳低效村的比例较大。建议未来应加强农业规模化经营、减少能源和物资投入、完善农业基础设施、推广节水节能新技术,在提高农业生产效率的同时推动农业低碳发展。
