2008-2013年云南省区域创新能力分析--《中国区域创新能力报告》解读

受全球金融危机影响及面临中国经济发展的“新常态”,云南省正处于转型升级的关键时期,提升区域创新能力、实现创新驱动至关重要。以《中国区域创新能力报告》为基础,依据各具体评价指标,从排名和指标值两个维度,对2008－2013年云南省区域创新能力进行纵向比较,同时将云南省与丝绸之路经济带其他省份进行横向比较。结果显示：云南省总体上创新能力不仅比较差,而且呈逐年下滑态势。故认为创新主体能力不强、创新要素配置较低、创新环境有待加强等三方面是制约云南区域创新能力较弱的原因。据此,应从政府、产业、企业三个层面寻求突破,以提升云南省的区域创新能力。

On C pk Assessment in the Presence of Tool Wear

Process capability indices are routinely used in manufacturing industries for process monitoring. A basic assumption while using process capability indices is that there are no assignable causes of variation present. However, when variation due to an assignable cause is present and is tolerated, the conventional methods of capability measurement become inaccurate. In this article, we suggest an estimate of C_pk assuming that the process capability changes dynamically. We obtain an exact form of the sampling distribution in the presence of a systematic assignable cause. We discuss the problem of testing whether a given process is capable. The critical values for different sample sizes are obtained based on the sampling distribution. An example involving tool wear problem is presented.     

Developing a variables repetitive group sampling plan based on process capability index C pk with unknown mean and variance

In this paper, variables repetitive group sampling plans are developed based on the process capability index C _pk when the quality characteristic follows a normal distribution with unknown mean and variance. The sampling plan parameters such as the sample size and the acceptance constant are determined to minimize the average sample number. Symmetric and asymmetric cases, in percent defectives due to two specification limits, are dealt with for specified combinations of acceptable quality level and limiting quality level. Tables are provided and examples are given to use proposed plans in practice.     

数字经济发展的碳减排效应研究——基于223个地级市的实证检验

发展数字经济是有效降低城市碳排放强度的重要抓手。利用2016—2020年中国223个地级市面板数据,实证研究了数字经济发展对城市碳减排效应的影响。研究发现:数字经济发展能够降低城市碳排放强度;数字经济发展通过提高能源环境效率和推进产业结构高级化、合理化等渠道降低城市碳排放强度;战略性新兴产业创新能力加强了数字经济发展对碳排放强度的抑制作用。数字经济发展在降低城市碳排放强度的进程中存在双重门槛,只有在数字经济发展超过特定门槛值时,碳减排效应才会显著,且其效应呈现出递减特征。异质性分析表明,数字经济发展能降低非中心城市和非资源型城市碳排放强度,但对降低中心城市和资源型城市碳排放强度的影响不显著。因此,政府应积极抓住大数据、云计算、人工智能等“新基建”的发展机遇,夯实数字经济基础底座,实现城市碳减排。     

Accuracy Analysis of the Percentile Method for Estimating Non Normal Manufacturing Quality

We consider asymmetric kernel estimates based on grouped data. We propose an iterated scheme for constructing such an estimator and apply an iterated smoothed bootstrap approach for bandwidth selection. We compare our approach with competing methods in estimating actuarial loss models using both simulations and data studies. The simulation results show that with this new method, the estimated density from grouped data matches the true density more closely than with competing approaches.     

Learning in and from projects: the learning modes and a learning capability model

Abstract

The notion of ‘project delivery’ is well embedded in and across the management and organizational sciences literature – generating a narrative that reflects and recognizes the instrumental nature of projects and programmes in strategy execution. Project management, as a distinct and well-established body of research enquiry, has increasingly sought to focus our attention on the impacts of complexity, risk and uncertainty in projects; the corollary being a desideratum to strengthen our theoretical understanding of how insight and learning from projects may influence improvements to organizational efficiency. The wider literature suggests that organizational learning remains a challenging proposition, particularly in the context of organizations operating in environments of high complexity. In this paper, we enhance the conversation on organizational learning through a series of case studies, generating evidence of thirteen ‘learning modes’. The paper proposes that mature organizations tend to exhibit a greater number of learning modes and that there is a tendency to capture and socialize knowledge with a greater emphasis on the context of the learning situation rather than the learning artefact in isolation. The empirical evidence gathered in this paper forms the basis of a capability model, characterized by the thirteen modes of learning. The model intimates that learning occurs, and is more effective, when knowledge and information are enacted in practice through the learning modes which form a nucleus of the organizational learning capability. The research concludes with a 'call to action' that emphasizes the strategic importance of learning practices and routines in project oriented-organizations.     

Employee financial wellness programs: Opportunities to promote financial inclusion?

ABSTRACT

Employee financial wellness programs (EFWPs) are a new practice that may promote financial inclusion by making it easier for workers with low- and moderate-incomes (LMI) to access financial services. We examine the strengths and limitations of workplace financial counseling, credit-building services, and small-dollar loans, and describe community collaboration to promote employee financial wellness. Findings suggest that these services are reaching a population that experiences financial exclusion, though evidence is mixed concerning how these services help workers with LMI resolve key financial challenges. Community collaboration focused on employee financial wellness presents opportunities to advocate for higher wages and better benefits.

Dynamic capabilities and high-tech entrepreneurial ventures’ performance in the aftermath of an environmental jolt

This paper contributes to studies on dynamic capabilities (DCs) by showing that a neglected environmental contingency – i.e. the occurrence of a jolt – shapes the DCs–performance relationship. We focus on high-tech entrepreneurial ventures because these are the firms that jolts affect most; in so doing, we also advance the understanding of DCs in the entrepreneurship field. We argue that, in the aftermath of an environmental jolt, the high-tech entrepreneurial ventures that use internationalization and new product development capabilities to modify their resource configuration and regain environmental fit enjoy better performance. Econometric estimates on a sample of 340 Italian high-tech entrepreneurial ventures confronting the consequences of the global economic crisis that began in 2008 confirm that separately using these two DCs has a positive performance effect. This effect is stronger for relatively smaller ventures. Interestingly, despite synergies should arise from the combined use of the two DCs, we do not detect any superadditive effects.
