简析《史记》中的社会饮食结构 ——以关中地区为中心

《史记》作为百科全书,对从传说中的黄帝到汉武帝中期长达三千多年的社会事象作了全景描绘,涉及各个阶层、各种人物的生活衣食住行的方方面面。作为生活头等的“食”在这部巨著中也是无处不在,对饮食（主要是“食”的方面）活动、礼仪、方式、对象和器具等都作了记载,涵盖了物质层面、制度层面、行为层面和精神文化层面。从《史记》记载来看,总体上可以说,我国古代逐渐形成以谷物为主食,肉类、蔬菜瓜果为副食的饮食方式。     

基于累积前景理论的多资产投资组合优化与实证研究

基于CPT视角的多风险资产投资组合模型,探讨投资者面对不同投资风险时的心理变化以及心理变化对其投资策略的影响。通过选取不同超额收益率及波动率水平的股票,测试投资策略对于风险态度指标的敏感度。研究表明,投资者面对不同风险具有明显地心理变化,并且其心理变化对投资策略具有显著的影响。具体表现在几个方面：投资者面对不确定收益时,表现出风险厌恶,面对不确定损失时,表现出风险偏好;投资者将无风险资产的投资收益作为心理参考点,所做的投资决策与相对于此参考点的相对财富水平的变化有关,而不是与传统理论中的绝对财富变化量相关。     

债券增信对企业创新的影响研究

债券增信能帮助企业以更好的条件发行债券,因而对企业的创新能力产生影响。通过对2007-2015年上市债券的研究发现：债券增信能够显著提升企业创新能力,但不同的增信方式（第三方保证、抵押和质押）其影响存在差异,其中,以采用抵押担保的增信方式效果为最佳;并且,债券增信对企业创新的提升效果在融资约束企业更为明显,从另一侧面证明了融资约束对企业创新的负面影响。     

明代宫廷书画收藏考略

明代宫廷的书画收藏十分丰富,嘉靖以后虽多有散出,但仍具有一定规模,直至明清鼎革之际宫廷所藏书画才散佚殆尽。明代宫廷所藏书画主要包括接收前代遗存、查抄籍没书画以及帝后臣工新创作书画几个部分。宫廷所藏书画主要由宦官机构司礼监负责保管,存放于质慎库中;另有部分历代帝王、君臣画像由印绶监保管,存放于古今通集库中。明代中叶以后,宫廷收藏书画通过充抵官员俸禄、偷窃等方式大量流散出宫,但同时也存在一定的补充和回流。明清易代之际,宫中所藏书画散佚殆尽,这为明末清初私人收藏家群体的崛起提供了机遇。     

全球替代性食物体系综述

在世界各地,农业食品领域的工业化造成了日益严重的环境、经济和社会问题,如环境污染、 大量碳排放、食品安全危机、小农边缘化和小农生计的难以维系。 为了应对这些问题,多个国家的不同 群体建立了多种多样的替代性食物体系,如社区支持农业、农夫市集、共同购买、社区菜园等。 替代性食 物体系自 2009 年进入中国至今已有十年,获得了较大发展。 然而,国内研究较少关注国际替代性食物 体系产生的背景及理念。 文章从替代食物体系的产生和发展、主要特征、国内外差异以及学术界的批判 等几个方面进行概述,全面介绍相关的关键问题和概念,为推动国内替代性食物体系研究的发展助力。     

Increasing implicit and explicit attitudes toward an organic food brand by referencing to oneself

In the last decades, theoretical and empirical work has been devoted to implicit attitudes toward a large range of food items. Despite the increasing development of green labels in the food market, to our knowledge no study has investigated implicit attitudes toward organic food nor has tried to change them. Capitalizing on the important role of the self in consumer or pro-environmental behavior, we aim to change or form implicit and explicit attitudes toward organic food brands using the self. Moreover, we investigate the possibility of changing hypothetical shopping behavior, brand identification, and attitude change persistence. Targeting two fictitious brands of organic food in two studies, we use the Self-Referencing (SR) task, an evaluative learning paradigm that relies on both the use of the self as a positive source of evaluation and the common action to classify the self and a target. We assess its effects on implicit attitudes, using one of the most common indirect measure (Implicit Association Test), as well as on explicit attitudes. We show that the SR manipulation results in more positive implicit attitudes, explicit attitudes, and to more frequent hypothetical choice of products for the eco-brand paired with the self compared to the other eco-brand. SR manipulation also results in higher level of brand identification. Moreover, changes in implicit attitude mediate changes in explicit attitude, identification, and hypothetical choice. Finally, we provide evidence for the persistence of the effect: Participants liked and identified more with the brand originally paired with the self even after removing the pairing with the self. The discussion is organized around the importance of taking into account implicit attitudes toward organic food brands and the usefulness of the self in changing or forming these attitudes.     

Assisting the High Administrative Court in Restricting Too Broad a Concept of Academic Judgment

I have received substantial monetary compensation and a formal apology from my first doctoral school, and a Ph.D. from another university. This essay describes my personal view on discussing the boundaries of academic judgment and research supervision with the ombudsman agency for higher education, and at the High Administrative Court of England and Wales. The Court’s judicial doctrine addresses substantial research accountability matters. It clarifies that although the Court and ombudsman agency must not interfere with academic judgment, not everything done by an academic can be considered as academic judgment. A Ph.D. supervisor can seriously fail to perform his/her duties.     

RESEARCHING RELATIONSHIPS FROM AN ATTACHMENT PERSPECTIVE: THE USE OF BEHAVIOURAL,INTERVIEW, SELF‐REPORT AND PROJECTIVE MEASURES

Having demonstrated its credentials as one of the more elegant and robust conceptualisations of human relationships, attachment theory has considerable relevance to social work. Attachment‐based research has flourished over the past few years and it now includes an impressive array of studies across the lifespan. This article considers four different measures used in attachment‐based research, although more discussion is devoted to interview and projective measures because they specifically embrace a psychodynamic approach in their design and analytic focus. The aim of the article is to provide a brief overview of each measure and to offer some illustrative examples using practice‐related material.     

R&D cooperation in collaborative consumption of research equipment: An ERGM approach

High-tech research infrastructure is essential for state-of-the-art research, but requires many resources. Relatively weak actors, such as SMEs, cannot secure enough of those. Applying the concept of collaborative consumption via digital platforms, we examine the cooperative behavior of Korean SMEs that share research equipment to overcome their lack of resources. Also, we analyze configurations of a collaborative consumption network using the Exponential Random Graph Model. Network structural factor analysis shows sufficient effects of network positive feedback through cooperative consumption with a variety of popular providers and attributes analysis shows that SMEs frequently engage in collaborative consumption with their counterparts in the same region. This new cooperative model can achieve a virtuous cycle of policies, as it increases the efficiency of research infrastructure, preventing the unnecessary building of new research equipment and enabling relocation of underutilized infrastructure and online reservation of equipment.     

Mixed integer (0–1) fractional programming for decision support in paper production industry

This paper presents an effective and efficient method for solving a special class of mixed integer fractional programming (FP) problems. We take a classical reformulation approach for continuous FP as a starting point and extend it for solving a more general class of mixed integer (0–1) fractional programming problems.To stress the practical relevance of the research we focus on a real-life application in paper production industry. The constantly advancing physical knowledge of large scale pulp and paper production did have a substantial impact on an existing DSS in which mixed integer (0–1) fractional programming is introduced. We show that the motivation to solve a real-life fractional programming problem can provide the basis for a new approach in a new context that has an added value of its own, even outside the given application area. We describe the main characteristics of the DSS, the necessity to develop a non-iterative solution procedure and demonstrate both the effectiveness and efficiency of the proposed approach from practical data sets.
