Beginning with last year’s centennial of the passage of the Third Home Rule Bill, Ireland commenced an extraordinary “Decade of Commemorations,” during which the entire island will recall the anniversaries of crucial historic events: the Dublin Lock-out, the Easter Rising, the “Ulster Sacrifice” of the Somme, Partition, and the Irish Civil War, to name a few. The high-profile public history that will be crafted to mark these events is likely to set the received narrative of the events for another century—and, in turn, will enter the interdisciplinary intellectual project of Irish Studies itself. With the special assistance of Dr. Mike Cronin, New Hibernia Review gathered four scholars (two historians, a literary scholar, and a social anthropologist) to discuss the implications, opportunities, and perils of the Decade of Commemorations. They conducted their discussion by e-mail over the summer of 2013.

The generation of ultrarelativistic positron beams with short duration (τe+≃30 fs), small divergence (θe+≃3 mrad), and high density (n e+≃1014-1015 cm-3) from a fully optical setup is reported. The detected positron beam propagates with a high-density electron beam and γ rays of similar spectral shape and peak energy, thus closely resembling the structure of an astrophysical leptonic jet. It is envisaged that this experimental evidence, besides the intrinsic relevance to laser-driven particle acceleration, may open the pathway for the small-scale study of astrophysical leptonic jets in the laboratory.

Concern for NGO accountability has been intensified in recent years, following the growth in the size of NGOs and their power to influence global politics and curb the excesses of globalization. Questions have been raised about where the sector embraces the same standards of accountability that it demands from government and business. The objective of this paper is to examine one aspect of NGO accountability, its discharge through annual reporting. Using Habermas’ (1984; 1987) theory of communicative action, and specifically its validity claims, the research investigates whether NGOs use their annual reporting process to account to the host societies in which they operate or steer stakeholder actions toward their own self-interests. The results of the study indicate that efforts by organizations to account are characterized by communicative action through the provision of truthful disclosures, generally appropriate to the discharge of accountability and in a manner intended to improve their understandability. At the same time, however, some organizations exhibit strategically oriented behaviors in which the disclosure content is guided by the opportunity to present organizations in a particular light and there appears a lack of rhetor authenticity. The latter findings cast doubt on the ethical inspiration of NGOs and the values they demand from business communities, and questions arise as to why such practices exist and what lessons can be learnt from them.

University classroom talk is a collaborative struggle to make meaning. Taking the perspectival nature of interaction as central, this paper presents an investigation of the genre of spoken academic discourse and in particular the types of activities which are orientated to the goal of collaborative ideas or tasks, such as seminars, tutorials, workshops. The purpose of the investigation was to identify examples of dialogicality through an examination of stance-taking. The data used in this study is a spoken corpus of academic English created from recordings of a range of subject discipline classrooms at a UK university. A frequency-based approach to recurrent word sequences (lexical bundles) was used to identify signals of epistemic and attitudinal stance and to initiate an exploration of the features of elaboration. Findings of quantitative and qualitative analyses reveal some similarities and differences between this study and those of US based classroom contexts in relation to the use and frequency of lexical bundles. Findings also highlight the process that elaboration plays in grounding perspectives and negotiating alignment of interactants. Elaboration seems to afford the space for the enactment of student stance in relation to the tutor embodiment of discipline knowledge.

This is a dataset of recordings and transcriptions of spoken English collected from a range of university classrooms. UNITALK is a modest-sized untagged synchronic specialized full-text corpus of spoken academic discourse collected from fifteen university classrooms. UNITALK was designed to study the genre of small group teaching contexts across academic divisions and subject disciplines and specifically designed to study those teaching events whose goal is to work on collaborative ideas or tasks. The corpus is over 100,000 words and can be used to investigate academic language use and small group university teaching and learning contexts.

Advocates of semi-structured interview techniques have often argued that rapport may be built, and power inequalities between interviewer and respondent counteracted, by strategic self-disclosure on the part of the interviewer. Strategies that use self-disclosure to construct similarity between interviewer and respondent rely on the presumption that the respondent will in fact interpret the interviewer's behaviour in this way. In this article we examine the role of interviewer self-disclosure using data drawn from three projects involving interviews with young people. We consider how an interviewer's attempts to ‘do similarity’ may be interpreted variously as displays of similarity or, ironically, as indicators of difference by the participant, and map the implications that this may have for subsequent interview dialogue. A particular object of concern relates to the ways in which self-disclosing acts may function in the negotiation of category entitlement within interview interactions.

Objective: The present study aimed to examine the role of health in consumers’ food purchasing decisions through investigating the nature of people’s discourse regarding health while conducting their food shopping.
Design: The study employed the think-aloud technique as part of an accompanied shop. All mentions of health and terms relating to health were identified from the data set. Inductive thematic analysis was conducted to examine how health was talked about in relation to people’s food choice decisions.
Setting: Supermarkets in Dublin, Republic of Ireland and Belfast, Northern Ireland.
Subjects Participants: (n 50) were aged over 18 years and represented the main household shopper.
Results: Responsibility for others and the perceived need to illicit strict control to avoid ‘unhealthy’ food selections played a dominant role in how health was talked about during the accompanied shop. Consequently healthy shopping was viewed as difficult and effort was required to make the healthy choice, with shoppers relating to product-based inferences to support their decisions.
Conclusions: This qualitative exploration has provided evidence of a number of factors influencing the consideration of health during consumers’ food shopping. These results highlight opportunities for stakeholders such as public health bodies and the food industry to explore further ways to help enable consumers make healthy food choices.

In contemporary political theory, perfectionists believe that the state should promote substantive conceptions of the good through its legislation. Supporters of neutrality, instead, claim that the state should refrain from doing so. In this article I analyse perfectionism in relation to Jürgen Habermas’ theory of discourse and deliberative politics (1996) and critique Habermas’ distinction between ‘ethical’ and ‘moral’ discourses (1984, 1990). By relating Habermas’ theory to George Sher’s account of perfectionism (1997), I argue that we can establish the meta-ethical grounds for a model of deliberation encompassing ethical matters (that is, questions concerning the good life) not confined to the limits of specific communities. I conclude by arguing that ethical deliberation is not only feasible but also desirable. Given the fact of ethical pluralism, and in order to show respect towards their fellow citizens, political perfectionists ought to be ready to show how their ethical claims (which they want to see translated into state policy) relate to deeper meta-ethical human goals on which we can ideally find a consensus through deliberation.

An ultra-relativistic electron beam passing through a thick, high-Z solid target triggers an electromagnetic cascade, whereby a large number of high energy photons and electron-positron pairs are produced. By exploiting this physical process, we present here the first experimental evidence of the generation of ultra-short, highly collimated and ultra-relativistic positron beams following the interaction of a laser-wake field accelerated electron beam with high-Z solid targets. Clear evidence has also been obtained of the generation of GeV electron-positron jets with variable composition depending on the solid target material and thickness. The percentage of positrons in the overall leptonic beam has been observed to vary from a few per cent up to almost fifty per cent, implying a quasi-neutral electron-positron beam. We anticipate that these beams will be of direct relevance to the laboratory study of astrophysical leptonic jets and their interaction with the interstellar medium.
