个人-组织价值观实现度匹配与绩效关系的实证研究——以科研团队为例

个人-组织价值观匹配成为当今西方组织管理心理学研究的热点领域,主要是因为价值观匹配能很好地预测个人的积极态度和行为结果。以190名科研团队成员为调查对象,分析个人价值观实现度、团队价值观实现度及其匹配与团队绩效的相关关系和作用影响。结果表明:个人、团队价值观实现度及其匹配与绩效有密切关系,且对绩效有显著预测作用。     

考虑服务水平的两级供应链系统信号博弈研究

针对由供应商和制造商构成的两级供应链系统,在不完全信息条件下,建立以服务水平作为传递信号的供应链动态博弈模型,分析供应链信号博弈中分离均衡的实现过程及存在条件,最终给出分离均衡下供应链质量管理的有效对策。研究表明,制造商能够根据获取的服务质量信号,对供应商的潜在行为进行分析,选择最佳的应对策略,降低自身的运营风险,增强供应链合作的稳定性。     

终极控股权、控制层级与经济增加值——基于北京上市公司数据

按照终极控股权和控制层级理论,将北京109家样本公司分为八类。用EVA验证各类公司的价值创造能力,结果得出:样本公司2009年的平均EVA值偏低,均值为0.03%;终极控股股东性质对EVA的影响不显著,控制层级与EVA显著负相关;非政府一级控股公司EVA值最高,其次是政府二级控股公司,他们显著优于政府控股四级控股公司和非政府三级控股公司。     

Association of Inflammatory Biomarker C-Reactive Protein, Lipid Peroxidation and Antioxidant Capacity Marker with HbF Level in Sickle Cell Disease Patients from Chattisgarh

This study was undertaken to determine the association of inflammatory biomarker, oxidative stress and antioxidant capacity marker with fetal haemoglobin (HbF) level among sickle cell trait and sickle cell disease (SCD) patients in Chattisgarh. The study group consisted of 51 SCD (SS) patients with painful episode, 49 SCD (SS) patients with steady state, 50 sickle cell trait (AS) and 50 controls. Malondialdehyde (MDA), CRP, total antioxidant power (FARP), total thiol and HbF levels were quantified. We found a significant positive (p < 0.0001) association between CRP and MDA levels and its inverse association with HbF level in SS patients. We also observed that antioxidant capacity had significantly positively (p < 0.0001) associated with HbF level. The protective effect of HbF was found, because the increase in HbF levels resulted in decrease in lipid peroxidation and inflammation in SCD patients. A decrease in the HbF level and its antioxidant capacity has been associated with the pathogenesis of SCD. These finding may explain the high level of HbF is ameliorating oxidative stress and inflammation in SCD patients.     

Impact of Chronic Lead Exposure on Selected Biological Markers

Lead poisoning remains a major problem in India due to the lack of awareness of its ill effects among the clinical community. Blood lead, δ-aminolevulinic acid dehydratase (δ-ALAD) and zinc protoporphyrin (ZPP) concentrations are widely used as biomarkers for lead toxicity The present study was designed to determine the impact of chronic lead exposure on selected biological markers. A total of 250 subjects, of both sexes, ranging in age from 20 to 70 years, were recruited. On the basis of BLLs, the subjects were categorized into four groups: Group A (BLL: 0–10 μg/dl), Group B (BLL: 10–20 μg/dl). Group C (BLL: 20–30 μg/dl) and Group D (BLL: 30–40 μg/dl) having BLLs of 3.60 ± 2.71 μg/dl, 15.21 ± 2.65 μg/dl, 26.82 ± 2.53 μg/dl and 36.38 ± 2.83 μg/dl, respectively. Significant changes in biological markers due to elevated BLLs were noted. The relation of BLL and biological markers to demographic characteristics such as sex, habits, diet and substances abuse (smoking effect) were also studied in the present investigation. Males, urban population, non-vegetarians, and smokers had higher blood lead levels. δ-ALAD activity was found to be significantly lower with increased BLL (P < 0.001), while the ZPP level was significantly higher with increased BLL (P < 0.001). Further, BLL showed a negative correlation with δ-ALAD (r = −0.425, P < 0.001, N = 250) and a positive correlations with ZPP (r = 0.669, P < 0.001, N = 250). Chronic lead exposure affects the prooxidant-antioxidant equilibrium leading to cellular oxidative stress.

基层政府绩效与受灾群众满意度的关系

选择四川省汶川地震某受灾城镇492名居民作为研究对象,采用路径分析方法研究巨灾应对的应急处置阶段和恢复重建阶段基层政府的绩效与受灾群众满意度之间的关系。结果显示,应急处置阶段的基层政府绩效对受灾群众的累积满意度没有直接影响,而是通过恢复重建阶段间接加以影响;无论是应急处置阶段还是恢复重建阶段,基层政府的能力都是影响受灾群众满意度的关键因素;工作效率对受灾群众的满意度影响不显著。因此,基层政府的治理能力建设是提升受灾群众累积满意度的关键要素,同时灾区建设不应将效率作为基层政府绩效评价的主要指标。     

基于灰色关联投影的陕南县域城镇化水平评价及对策研究

以陕南28个县区为研究对象,通过构建人口、经济、社会生活为一体的县域城镇化发展水平综合评价指标,采用熵权法确定权重,建立了陕南县域城镇化灰色关联投影模型;运用spss17.0和ArcGIS分别进行聚类分析和空间分析,从空间尺度对陕南县域城镇化水平进行综合评价.结果表明：陕南县域城镇化水平普遍较低,发展不均一.针对研究结果,从环境优先,扶持特色城镇,搞好基础设施建设,管理创新等方面提出加快陕南县域城镇化发展的对策,有利于陕南经济的可持续发展.
