Effects of the social dominance orientation on environmental attitudes of Chilean university students / Efectos de la orientación a la dominancia social sobre las actitudes ambientales de universitarios chilenos

By adopting a multidimensional approach to environmental attitudes (apathy, anthropocentrism, connectedness and emotional affinity with nature), this study explores the relationships between these dimensions, social dominance orientation (SDO) and political orientation. Two hundred and sixty-two Chilean university students filled out an ad hoc online questionnaire. Two confirmatory factorial analyses showed the four typologies of environmental attitudes and the two factors for SDO, which are labelled group dominance and opposition to equality. Through hierarchical regressions, group dominance showed higher explanatory power of environmental attitudes than political orientation. Furthermore, using the bootstrap procedure we showed that group dominance mediated between political orientation and attitudes of apathy, anthropocentrism and connectedness, while opposition to equality mediated between apathy and emotional affinity. We conclude that SDO is an important variable for measuring political ideology while also providing new nuances when analysing the relationships with environmental attitudes.     

The Importance of “Empty Gestures” in Recovery: Being Human Together

What do clients/patients want or value from their encounters with healthcare providers? Based on ethnographic research conducted with individuals suffering from drug addiction and mental health issues, this article argues that clients/patients treasure “everyday” or “human” interaction with medical staff. Everydayness is accomplished through three generic social processes: **co‐silence, inclusion in back‐stage activity, and physical dramatizations of authenticity. These processes and other ordinary interactional strategies for “being human together” should be seen as vital tools for recovery.     

P2P 网络借贷研究进展及中国问题研究展望

P2P ( 个人对个人) 网络借贷是指通过网络借贷平台，在全球范围内实现个人与个人或小微企业间的小额信用借贷交易． P2P 网络借贷作为全新的互联网金融服务受到商业界的高度关注，而且发展成为学术研究的国际前沿领域． 对 P2P 网络借贷相关研究文献进行了综述，具体从影响借贷交易的信息因素、羊群效应以及社交网络等 3 个方面分析了该领域研究的现状和发展脉络． 因为中国已超越美国成为全球最大的 P2P 网络借贷交易市场，所以结合中国的具体情境和问题，提出了未来研究工作的展望．     

劳动力转移对城乡居民收入差距的非线性影响研究

借鉴已有相关研究成果,将劳动力转移、农业技术水平与城乡居民收入差距联系起来思考,可以具体地考察劳动力转移对城乡居民收入差距的影响.文章以农业技术水平作为门槛变量,选取2009—2019年中国31个省份的面板数据,利用泰尔指数测定城乡收入差距,以劳动力转移作为核心解释变量构建面板门槛模型,实证得出劳动力转移对城乡居民收入差距的非线性影响.研究发现:劳动力转移可以缩小城乡居民收入差距,且该影响具有单一门槛效应.在农业技术水平较低时,劳动力转移对城乡居民收入差距收敛效应较小;当农业技术水平越过门槛值达到较高水平后,劳动力转移对缩小城乡居民收入差距的效果几乎增加了一倍.此后,通过替换解释变量泰尔指数为城乡人均可支配收入比、替换核心解释变量农业技术水平为农业生产效率重新建立面板门槛模型,发现上述结论仍然成立,其检验结果具有较强的稳健性.文章将农业技术进步、劳动力转移、城乡居民收入差距这三个重要变量纳入同一模型框架中,在加深劳动力流动影响城乡居民收入差距这一视角的研究的同时,对缩小城乡居民收入差距政策的制定提供了重要的参考意义.     

空间相互作用与城市经济增长--来自长三角的证据

基于以往研究对空间相互作用方向性考虑不足的事实，文章以长三角133个县市为例，构建了融合新经济地理学与中心地理论的理论框架，将表征空间需求关联的总体市场潜能细分为来自同层级、高等级、低等级三个方向，利用空间计量模型估计了总体及不同方向的空间相互作用对长三角地区人均GDP增长与人口增长的效应。结果显示：在控制空间依赖导致的间接溢出效应等因素后，并未发现存在要素价格绝对调整或要素数量绝对调整的证据，总体市场潜能的提高同时促进了城市人均GDP增长与人口增长；就不同方向的空间相互作用而言，大城市的自身发展有利于中等城市的人均GDP增长，大城市之间、大城市对下级城市、小城市对上级城市形成了人口增长的良性互动格局，而中等城市之间以及中等城市对大城市的人口增长则表现为回流效应。     

Methodological considerations in the use of name generators and interpreters

With data from the Clergy Health Initiative Longitudinal Survey, we look for interviewer effects, differences between web and telephone delivery, and panel conditioning bias in an “important matters” name generator and interpreter, replicated from the U.S. General Social Survey. We find evidence of phone interviewers systematically influencing the number of confidants named, we observe that respondents assigned to the web survey reported a larger number of confidants, and we uncover strong support for panel conditioning. We discuss the possible mechanisms behind these observations and conclude with a brief discussion of the implications of our findings for similar studies.     

Follow the leader! The peer effect in aid supply decisions

This study assesses the existence of imitative behaviour among donors in terms of their aid supply. The urgency in addressing this subject is motivated by an increasing degree of aid volatility and unpredictability which may be linked to this imitative behaviour. Our results highlight that while any connection among donor peers is a potential channel for the transmission of aid volatility, the extent of such volatility decreases significantly in the presence of established imitative behaviour. This result suggests that the promotion of donor imitative behaviour would contribute to containing the current and growing trend of volatility in aid supply.     

Reputation spillover effects from grant‐providing institutions

There is a broad academic discussion about the impact of funding grants from a foundation or a government department on individual support intentions toward the nonprofit organization receiving the grant. However, the role of the grant provider's reputation has frequently been overlooked. In this study, we experimentally tested whether there is a reputation spillover effect of a grant‐providing organization. Based on a real‐life example, we asked citizens to rate their willingness to donate to a nonprofit organization, and we experimentally manipulated the available information on funding sources. We test this for both a government department and a foundation as a grant provider. Our results suggest that not the act of receiving a grant, but the citizens' awareness about the funding organization—at least in the case of a foundation—has an impact on support intentions. In contrast, for a prominent government department as a grant provider, we did not find support for a reputation spillover effect.     

农业机械化服务对粮食生产成本效率的影响——来自中国小麦主产区的经验证据

运用超越对数SFA模型测算1994—2016年中国15个小麦主产地区成本效率，继而构建空间杜宾计量模型考察农业机械化服务对小麦生产成本效率的直接影响与空间溢出效应。结果表明：中国小麦生产成本效率仍存在17.3%的损失；农业机械化服务对小麦成本效率具有正向显著的直接效应和空间溢出效应，即本区域农机化水平对其他区域小麦成本效率有显著的正向影响；从空间维度来看，农业机械化的空间溢出效应主要表现在经度相近地区之间，纬度相近地区之间并不显著；从时间维度看，2004年前后农业机械化的空间溢出效应具有明显差异，2004年之后空间溢出效应更加明显。据此提出农机补贴向农机服务组织倾斜，建设和推广农机信息平台以及作物种植沿经度布局的政策建议。     

技术创新与企业就业效应--基于微观企业调查数据的实证分析

利用2012年世界银行关于中国工业企业的调查数据，从流程创新、产品创新和企业研发三个维度分析了短期内技术创新对就业增长的影响。结果显示，流程创新与就业增长显著负相关；产品创新与就业增长显著负相关；企业研发与就业增长负相关，但较前两者显著性较弱。进一步研究发现，与东部沿海地区相比，中西部地区技术创新的就业替代效应更为明显。鉴于上述研究结果，对现有技术创新方式和政策提出相应的对策建议。
