Preference intensity representation: strategic overstating in large elections

If voters vote strategically, is it useful to offer them the possibility of expressing nuanced opinions, or would they always overstate the intensity of their preferences? For additive voting rules, say that a ballot is extremal if it is neither abstention-like nor can be expressed as a mixture of the available ballots. We give a sufficient condition for strategic equivalence: if two rules share the same set of extremal ballots (up to an homothetic transformation), they are strategically equivalent in large elections. This condition is also necessary for the strategic equivalence of positional rules. These results do not hold for small electorates.     

The Global Alliance for Public Relations and Communication Management: Origins,influences, issues and prospects

This paper chronicles the formation and development of the Global Alliance for Public Relations and Communication Management (GA) up to 2002. It sets the GA's genesis within the context of other internationalisation initiatives undertaken by the wider public relations practitioner community and draws links between the formation of the GA and the emerging phenomenon of globalisation. The paper's intent is to describe the formation of the GA from a historical perspective, to understand the forces that led to its creation and to appreciate the different drivers and motivation of founding members. These factors provide a springboard to consider some of the issues that currently challenge GA, some of which were inherent in the governance model it chose at its inception.     

Gender and Supportive Co‐Worker Relations in the Medical Profession

Women's growing numerical representation in the professions has not necessarily translated into women being truly integrated in these occupations. Questionnaire data are used to examine whether female physicians are socially integrated in the male‐dominated profession of medicine in terms of the support they receive from their medical colleagues compared to male physicians. The literature on tokenism and homophily suggests that women in male‐dominated professions receive less support than their male colleagues, whereas the social support literature predicts that women typically receive more emotional support than men but less informational and instrumental support. The results of this study shed light on the complex and multi‐layered ways in which gender is relevant to our understanding of the extent to which co‐workers provide empathy, information and assistance to one another.     

Left Behind by Parents in China: Internal Migration and Adolescents’ Well-Being

This study investigates how growing up as a left-behind child due to parents’ labor migration in China is associated with adolescents’ cognitive and socioemotional development, based on data from the China Family Panel Studies. We find that adolescents do worst when both parents are absent in all developmental indicators we examined: short-term and long-term word recall tests, numeracy test, self-concept, and self-expectation of educational attainment. However, the differences between left-behind children and those in rural two-parent families are not statistically significant. Left-behind adolescents do have significantly lower well-being than those in urban two-parent families. These differences can largely be accounted for by father's education, family spending on the adolescent's education, quality of parenting, and the social support available to an adolescent. The gap in Chinese adolescents' development is, thus, not so much related directly to how many parents one grows up with as it is to whether one grows up in a rural or urban environment.     

Processes Employed by Social Work Practitioners in Child Welfare for Exchanging and Using Knowledge

Organisations in the health and social services sector expend a considerable amount of energy promoting the implementation of better practices and research data use in their establishments. In the field of social work, several studies suggest that social work practitioners do not make great use of scientific knowledge and tend to favour knowledge acquired from their colleagues or through their own occupational experience. However, interactions between types of knowledge are rarely analyzed in explanations proposed by the scientific literature. Based on research conducted with social work practitioners in child welfare, this article discusses the different ways that they acquire knowledge.     

100 key research questions for the post‐2015 development agenda

The Sustainable Development Goals (SDGs) herald a new phase for international development. This article presents the results of a consultative exercise to collaboratively identify 100 research questions of critical importance for the post‐2015 international development agenda. The final shortlist is grouped into nine thematic areas and was selected by 21 representatives of international and non‐governmental organisations and consultancies, and 14 academics with diverse disciplinary expertise from an initial pool of 704 questions submitted by 110 organisations based in 34 countries. The shortlist includes questions addressing long‐standing problems, new challenges and broader issues related to development policies, practices and institutions. Collectively, these questions are relevant for future development‐related research priorities of governmental and non‐governmental organisations worldwide and could act as focal points for transdisciplinary research collaborations.     

西方理性主义时代的解释学——在语法和批判之间

早在理性时代和启蒙时代(17、18世纪),西方解释学的哲学化进程就迈出了重要的一步,而不是等到施莱尔马赫出现以后。理性主义时代的解释学集中体现在丹豪尔的普遍解释学、克拉登尼乌斯的教育解释学、迈耶尔的符号解释学以及宗教的系统内的虔信派的情感和应用的解释学。它们都从不同的角度突出了解释学的普遍性,具有深刻的时代特点。     

Projection‐Based Statistical Inference in Linear Structural Models with Possibly Weak Instruments

It is well known that standard asymptotic theory is not applicable or is very unreliable in models with identification problems or weak instruments. One possible way out consists of using a variant of the Anderson–Rubin ((1949), AR) procedure. The latter allows one to build exact tests and confidence sets only for the full vector of the coefficients of the endogenous explanatory variables in a structural equation, but not for individual coefficients. This problem may in principle be overcome by using projection methods (Dufour (1997), Dufour and Jasiak (2001)). At first sight, however, this technique requires the application of costly numerical algorithms. In this paper, we give a general necessary and sufficient condition that allows one to check whether an AR‐type confidence set is bounded. Furthermore, we provide an analytic solution to the problem of building projection‐based confidence sets from AR‐type confidence sets. The latter involves the geometric properties of “quadrics” and can be viewed as an extension of usual confidence intervals and ellipsoids. Only least squares techniques are needed to build the confidence intervals.     

Polarization: Concepts,Measurement, Estimation

We develop the measurement theory of polarization for the case in which income distributions can be described using density functions. The main theorem uniquely characterizes a class of polarization measures that fits into what we call the “identity‐alienation” framework, and simultanously satisfies a set of axioms. Second, we provide sample estimators of population polarization indices that can be used to compare polarization across time or entities. Distribution‐free statistical inference results are also used in order to ensure that the orderings of polarization across entities are not simply due to sampling noise. An illustration of the use of these tools using data from 21 countries shows that polarization and inequality orderings can often differ in practice.
