Social Exclusion, Social Isolation and the Distribution of Income

Social exclusion can be distinguished from social isolation, defining social isolation as the phenomenon of non-participation (of an individual or group) in a society's mainstream institutions, while reserving 'social exclusion' for the subset of cases in which social isolation occurs for reasonsthat are beyond the control of those subject to it. The familiar form of social exclusion affects those who are unable to participate in the institutions patronised by the majority. There is also, however, exclusion of the majority by a minority who are in a position to opt out of the mainstream institutions: the epitome of this is the 'gated community'. Social exclusion is a violation of the demands of social justice in two ways: it conflicts with equality of opportunity and is associated with an inability to participate effectively in politics. An alternative account of what is wrong with social exclusion is that it undermines social solidarity. Voluntary social isolation has the same effect, but is less likely to have such adverse consequences. The relation between social exclusion and the distribution of income is not the same in all societies. However, for a society such as that of Britain, it seems plausible that to avoid the social exclusion of a minority it is necessary for nobody to have less than half the median income, and that to avoid the social exclusion of the majority it is necessary for only a few to have more than three times the median income.Social exclusion, income distribution

Poncelet's Theorem, Paraorthogonal Polynomials and the Numerical Range of Compressed Multiplication Operators

There has been considerable recent literature connecting Poncelet's theorem to ellipses, Blaschke products and numerical ranges, summarized, for example, in the recent book [11]. We show how those results can be understood using ideas from the theory of orthogonal polynomials on the unit circle (OPUC) and, in turn, can provide new insights to the theory of OPUC.Comment: 46 pages, 4 figures; minor revisions from v1; accepted for publication in Adv.

Pay, Performance, and Participation

Our chapter identifies key dimensions on which organizations make employee compensation decisions and examines the emerging research evidence on the consequences of such decisions for attitudes, behaviors, and organization performance. We provide some general suggestions that may prove helpful in future research. First, there is increased recognition that pay decisions take place in the context of implicit or explicit contracts between employees and specific organizations. As a result, we encourage researchers to continue to give greater attention to the role of organization differences in compensation. Second, because pay is multidimensional, attention should not be restricted to organization differences in pay level. Organization differences in benefits, structure, and means of recognizing individual employees contributions also warrant attention. As an example of how the focus can be expanded, we provide new empirical evidence on organization differences in the market sensitivity of pay structures. Third, we note that the success of pay programs depends not only on decisions about pay per se, but also the process used in making communicating, and administering such decisions. More broadly, the influence of contextual factors, such as the nature of other employee relations practices (e.g., staffmg, development, employment security), needs to be considered to a greater extent in compensation research. In addition to these broad suggestions, we provide specific ideas on future research directions throughout the chapter

Surveying the Scene: how Representatives’ Views Informed a New Era in Irish Workplace Dispute Resolution

The Workplace Relations Act 2015 introduced a major overhaul of workplace dispute resolution bodies in Ireland, streamlining a complicated system for resolving workplace disputes comprising multiple fora into a two-tier structure. The article describes and analyses the results of two surveys undertaken by the author of the views of employment law and industrial relations practitioners and other representatives in Ireland before the reforms in 2011 and after the reforms in 2016. This article describes the purpose, methodology and considers the results of both surveys. The 2011 survey informed the agenda for reforming the Irish workplace dispute resolution system in 2015. The 2016 survey informed the new workplace dispute resolution bodies where improvements could be made. The impact of these surveys will be considered in the context of recent developments in the operation of the new system

Using Sparse Semantic Embeddings Learned from Multimodal Text and Image Data to Model Human Conceptual Knowledge

Distributional models provide a convenient way to model semantics using dense embedding spaces derived from unsupervised learning algorithms. However, the dimensions of dense embedding spaces are not designed to resemble human semantic knowledge. Moreover, embeddings are often built from a single source of information (typically text data), even though neurocognitive research suggests that semantics is deeply linked to both language and perception. In this paper, we combine multimodal information from both text and image-based representations derived from state-of-the-art distributional models to produce sparse, interpretable vectors using Joint Non-Negative Sparse Embedding. Through in-depth analyses comparing these sparse models to human-derived behavioural and neuroimaging data, we demonstrate their ability to predict interpretable linguistic descriptions of human ground-truth semantic knowledge.Comment: Proceedings of the 22nd Conference on Computational Natural Language Learning (CoNLL 2018), pages 260-270.
