长江经济带绿色金融与产业绿色发展耦合协调研究

在梳理绿色金融与产业绿色发展的耦合机理的基础上,构建耦合协调度模型,利用长江经济带九省二市2012—2017年数据,分析长江经济带各省市绿色金融与产业绿色发展耦合协调关系。研究发现：第一,长江经济带绿色金融促进产业绿色发展,产业绿色发展反哺绿色金融成效显著,二者已达到良性共振耦合,耦合协调度不断提高,发展阶段经历了勉强协调、初级协调、中级阶段到良好协调,并向着优质协调靠拢;第二,上游地区产业绿色发展已形成了区域内合作机制,产业绿色发展迅速,绿色金融与产业绿色发展耦合协调度自2012年以来上升最快;第三,九省二市绿色金融与产业绿色发展的基础和侧重点不同,二者耦合协调度呈现一定差异,但都达到了良好协调阶段。针对长江经济带绿色金融和产业绿色发展二者耦合协调度现状,提出了相应的对策建议。

Costs of promoting cancer screening: Evidence from CDC’s Colorectal Cancer Control Program (CRCCP)

The Colorectal Cancer Control Program (CRCCP) provided funding to 29 grantees to increase colorectal cancer screening. We describe the screening promotion costs of CRCCP grantees to evaluate the extent to which the program model resulted in the use of funding to support interventions recommended by the Guide to Community Preventive Services (Community Guide). We analyzed expenditures for screening promotion for the first three years of the CRCCP to assess cost per promotion strategy, and estimated the cost per person screened at the state level based on various projected increases in screening rates. All grantees engaged in small media activities and more than 90% used either client reminders, provider assessment and feedback, or patient navigation. Based on all expenditures, projected cost per eligible person screened for a 1%, 5%, and 10% increase in state-level screening proportions are $172, $34, and $17, respectively. CRCCP grantees expended the majority of their funding on Community Guide recommended screening promotion strategies but about a third was spent on other interventions. Based on this finding, future CRC programs should be provided with targeted education and information on evidence-based strategies, rather than broad based recommendations, to ensure that program funds are expended mainly on evidence-based interventions.     

An integrated model based on statistical process control and maintenance for two-stage dependent processes

The close relationship between quality and maintenance of manufacturing systems has contributed to the development of integrated models which use the concept of statistical process control (SPC) and maintenance. This article demonstrates the integration of the Shewhart individual-residual (Z_X ? Z_e) joint control chart and maintenance for two-stage dependent processes by jointly optimizing their policies to minimize the expected total costs associated with quality, maintenance and inspection. To evaluate the effectiveness of the proposed model, two stand-alone models—a maintenance model and an SPC model—are proposed. Then a numerical example is given to illustrate the application of the proposed integrated model. The results show that the integrated model outperforms the two stand-alone models with regard to the expected cost per unit time. Finally, a sensitivity analysis is conducted to develop insights into time parameters and cost parameters that influence the integration efforts.     

Testing hypotheses for the growth curve model when the data are incomplete

Kleinbaum (1973) developed a generalized growth curve model for analyzing incomplete longitudinal data. In this paper the small sample properties of several related test statistics are investigated via Monte Carlo techniques. The covariance matrix is estimated by each of three non-iterative methods. The null and non-null distributions of these test statistics are examined.

The impact of internal communication on strategic and economic effects in Serbian companies

This paper presents the research results in relation to examining and defining dependences and the impact of internal communication on certain strategic and economic business effects. Serbian companies were the focus of this research. The data were collected by polling 100 managers from 100 companies. Afterwards, multivariate regression and correlation was carried out in the aim of the final determination of requested dependences. This research confirmed a strong positive relation between internal communication and strategic and economic business effects.
