The Effect of Tacticity on the Conformational Properties of Poly(1-olefin sulfone)s

The effect of tacticity on the conformational properties of poly(olefin sulfone)s was studied. Tactic polymers, prepared from racemic thiirane monomers using chiral inititators were compared with atactic polymers prepared by free radical co-polymerisation of the 1-olefin with sulfur dioxide. Analysis of the XRD patterns showed that the tactic polymers formed more ordered structures in the bulk with longer layer spacings, consistent with a model in which their side chains meet at the tips in contrast with the atactic polymers whose side chains interdigitate. 13C MAS nmr experiments suggest that as tacticity increases so too does the proportion of C-S bonds in the gauche conformation, however the proportion of S-C bonds in the trans conformation falls, in contrast to a reported molecular mechanics study. Finally, DSC measurements on the polymers with longer side chains showed the presence of two endotherms on heating, illustrating definite liquid crystalline behaviour.

Redundancy and Workplace Occupation: The Case of the Republic of Ireland

Purpose – This paper aims to examine the antecedent influences and merits of workplace occupations as a tactical response to employer redundancy initiatives.

Design/methodology/approach – The data are based on analysis of secondary documentary material reporting on three workplace occupations in the Republic of Ireland during 2009.

Findings – Perceptions of both procedural (e.g. employer unilateral action) and substantive (e.g. pay and entitlements) justice appear pivotal influences. Spillover effects from other known occupations may also be influential. Workplace occupations were found to produce some modest substantive gains, such as enhancing redundancy payments. The tactic of workplace occupation was also found to transform unilateral employer action into scenarios based upon negotiated settlement supported by third-party mediation. However the tactic of workplace occupation in response to redundancy runs the risks of potential judicial injunction and sanction.

Research limitations/implications – Although operationally difficult, future studies should strive to collect primary data workplace occupations as they occur.

Originality/value – The paper identifies conditions conducive to the genesis of workplace occupations and the extent to which the tactic may be of benefit in particular circumstances to workers facing redundancy. It also contextualises the tactic in relation to both collective mobilisation and bargaining theories in employment relations.

'Battling in Brussels': The DUP and the European union

Although the Democratic Unionist Party (DUP) does not conform to the model of Europeanization outlined by Ladrech (2002), there is some evidence of change along the lines identified by De Winter and Gomez-Reino (2002) with reference to other European ethnoregionalist parties. For example, the DUP has certainly adapted its behaviour and policies at both local and European levels with a view to exploiting new political opportunities offered by Europeanization. However, De Winter and Gomez-Reino's argument that participation in European institutions has made formerly-Eurosceptic ethnoregionalist parties 'moderate Eurocritics' does not fully apply to the DUP. The DUP continues to demonstrate a number of Eurosceptic characteristics, including ones grounded in extreme religious interpretations of the purpose and process of European integration. Nevertheless, the party's Eurosceptic outlook does not prevent it from being willing to 'battle in Brussels' (as put in its 2009 manifesto for the European elections) in order to serve domestic (party) interests - a tactic not dissimilar to the DUP's approach to Northern Ireland politics in general.

Inside the tent: Community and government in refugee camps

Refugee camps are increasingly managed through a liberal rationality of government similar to that of many industrialized societies, with security mechanisms being used to optimize the life of particular refugee populations. This governmentality has encompassed programmes introduced by the United Nations High Commissioner for Refugees (UNHCR) and various non-governmental organizations (NGOs) to build and empower communities through the spatial technology of the camp. The present article argues that such attempts to ‘govern through community’ have been too easily dismissed or ignored. It therefore examines how such programmes work to produce, manage and conduct refugees through the use of a highly instrumentalized understanding of community in the spatial and statistical management of displaced people in camps. However, community is always both more and less than what is claimed of it, and therefore undermines attempts to use it as a governing tactic. By shifting to a more ontological understanding of community as unavoidable coexistence, inspired by Jean-Luc Nancy, we can see how the scripting of and government through community in camps is continually exceeded, redirected and resisted. Ethnographies of specific camps in Africa and the Middle East enable us both to see how the necessary sociality of being resists its own instrumentalization and to view the camp as a spatial security technology. Such resistance does not necessarily lead to greater security, but it redirects our attention to how community is used to conduct the behaviour of refugees, while also producing counter-conducts that offer greater agency, meaning and mobility to those displaced in camps.
