认同和践行社会主义核心价值体系的路径探讨

就当前社会主义核心价值体系建设实际而言,各地通过有效载体传播、灌输、渗透,使核心价值体系逐步内化为人民群众的价值追求,使核心价值体系在社会民众中发挥了重要的引领作用。另一方面,社会大众认同与践行核心价值体系仍然存在诸多问题。我们要认真贯彻落实党的十八大精神,积极拓展认同和践行社会主义核心价值体系的有效路径,特别强调党政干部带好头、宣传教育要做到“三贴近”、利益格局调整的合理及时。     

On the Erasure of race in control culture discourse: a case study of Trayvon Martin’s role in the Black Lives Matter movement

ABSTRACT

In this paper, we analyze an emergent cultural clash between: (a) how media outlets and other control culture institutions have portrayed events related to Black Lives Matter, and (b) the complex reality of Black Lives Matter movements as they have developed through embodied, intersectional, and always socially situated forms of direct collective action. In focusing specifically on American mainstream media coverage of the killing of Trayvon Martin, we argue that, given the history of white supremacy in America, such journalistic accounts generally fail to provide an adequate socio-historical context for emergent social movements in the vein of Black Lives Matter. In framing such movements, at worst, as anti-American terrorist organizations, though more regularly as social constellations of misplaced anger, American control culture institutions have consistently reinforced a certain set of logical contradictions found across broader discussions about race throughout the history of America. Finally, drawing on the theory of play proposed by Gregory Bateson, we outline how a form of subverting mainstream journalistic framing techniques is enacted and embodied creativity through the communally oriented tactics successfully deployed by social movements like Black Lives Matter.     

Who decides the position for birth? A follow-up study of a randomised controlled trial

BackgroundPhysical benefits are suggested for women and their babies when women adopt an upright position of their choice at birth. Available care options during labour influence women's impressions of what intrapartum care is. This indicates that choice of birth positions may be determined more by midwives than by women's preferences.QuestionThe aims of this study were to investigate factors associated with adherence to allocated birth position and also to investigate factors associated with decision-making for birth position.MethodAn invitation to answer an on-line questionnaire was mailed.FindingsDespite being randomised, women who gave birth on the seat were statistically significantly more likely to report that they participated in decision-making and that they took the opportunity to choose their preferred birth position. They also reported statistically significantly more often than non-adherers that they felt powerful, protected and self-confident.ConclusionsMidwives should be conscious of the potential impact that birth positions have on women's birth experiences and on maternal outcomes. Midwives should encourage women's autonomy by giving unbiased information about the birth seat. An upright birth position may lead to greater childbirth satisfaction. Women's experience of and preferences for birth positions are consistent with current evidence for best practice.     

地方性工科院校高层次人才引进的若干思考

地方性工科院校高层次人才引进相对困难,特别是人才规划目标缺乏特色、人才评价机制尚不合理、人才队伍建设比较模糊等。这些内在问题的存在,是这类高校高层次人才引进面临的主要矛盾。通过围绕学校顶层设计制订科学合理的人才规划目标,建立以创新和质量为导向的考核评价及服务体系,转变人才引进外延式的扩张到内涵式的发展道路,将高层次人才引进工作和学校的总体发展战略结合起来,使其在促进高校又好又快发展中发挥引领和带动作用。     

The Prevalence of Problem Gambling Among U.S. Adolescents and Young Adults: Results from a National Survey

A random telephone survey was conducted with a representative sample of 2,274 U.S. residents aged 14–21. The prevalence of problem gambling, as measured by the SOGS-RA, was 2.1%. Sixty-eight percent (68%) of the respondents had gambled in the past year, and 11% had gambled more often than twice per week. Males had much higher gambling involvement than females, and gambling involvement increased among older respondents. Blacks were less likely than average to have gambled in the past year, but if they gambled, they were more likely to do so frequently. Low SES respondents were less likely to have gambled in the past year, but if they gambled, they were more likely to be problem gamblers. Life transitions that are associated with assuming adult roles (employment, living independently of parents, non-student status) are also associated with greater gambling involvement. The rates of problem and pathological gambling were lower than those in an adult survey conducted earlier, when measured with the same questionnaire.     

Scheduling to minimize stringer utilization for continuous annealing operations

In this paper we present a mathematical program and heuristic algorithms to schedule coils for the production operations in a copper (or steel) coil manufacturing industry. The processing facility uses continuous operations for processing (e.g., galvanizing and annealing) while the handling unit is a discrete coil. The ends of coils are “stitched” or welded together to enable continuous processing, and the joint is later sheared off to obtain the processed coils. Processing constraints impose restrictions on the compatibility between a pair of coils that are overcome by introducing a dummy coil called stringer, which is very expensive to a mill. This paper deals with modeling the sequencing/scheduling problem of coils on parallel non-identical machines to minimize stringer utilization. Both computational and practical experiences show the efficiency and effectiveness of the solution approaches. Implementing these methods in an actual coil annealing facility resulted in 65% reduction in stringer utilization.     

两阶段DEA前沿面投影问题研究——兼对我国上市银行运营绩效进行评价

DEA方法,即数据包络分析方法,是一种用于评价决策单元(Decision Making Units,DMUs)相对有效性的实证方法。近年来DEA方法已经广泛的应用于各行各业的绩效评价中,并发展出两阶段DEA方法。两阶段DEA方法相对于传统DEA方法的优势在于,它不但可以提供被评价对象的总体效率值,还可以分别生成每一阶段的效率值。但正是由于中间要素的存在,按照传统的DEA方法来调整两阶段DEA投入、产出要素的优化过程已不能成功投影在有效前沿面上。本文基于两阶段DEA方法,通过加入"虚拟中间要素"在两阶段DEA中嵌入一个"虚拟阶段",这样不但完善了两阶段DEA的逻辑结构,而且成功的将被评价单元投影到有效前沿面。最后本文应用以上方法对我国上市银行的运营绩效进行了实证分析。实证结果令我们意外的是,国有商业银行运营绩效优于股份制银行。

The Role of Revenue‐Focused Managerial Performance Measures in Supply Chain Coordination

Many firms employ revenue‐focused managerial performance measures (RF‐MPMs) that cause managers to worry more about revenues than about costs. Although this can seemingly misalign the interests of a manager, we show that the use of such measures can help supply chain partners to overcome hold‐up issues with respect to capacity and promotion investments. We develop a game theoretic model in which two supply chain partners engage in repeated interactions in which the supplier invests in capacity and the buyer invests in demand promotion. Following the realization of demand in each period, the two firms negotiate over the output quantity and wholesale price. The novelty of our model is that we allow the owners of each firm to delegate decision‐making power and negotiating responsibility to a free‐agent manager. We characterize the conditions under which the owners of both firms employ RF‐MPMs in equilibrium and benefit from doing so. For a special case of our model, we show that for the owners of the buyer, an RF‐MPM is equivalent to a price only relational contract, and that it complements a price and quantity relational contract as a mechanism for mitigating hold‐up issues.     

Newsvendor Pricing Problem in a Two‐Sided Market

We study the pricing problem of a “platform” intermediary to jointly determine the selling price of the platforms (hardware) sold to consumers and the royalty charged to content developers for content (software), when the demands for content and for platforms are interdependent. Our model elucidates the impact of supply chain replenishment costs and demand uncertainty on the strategic issues of platform pricing in a two‐sided market.
