Thie examines the continuing role that the landed class enjoyed in Northern Ireland in contrast to the experience of their fellow landlords in the rest of Ireland following Partition. It argues that the senses of tradition and continuity which the unionist population in particular attributed to the old landed elite gave them an important role in bolstering the newly created state of Northern Ireland. In turn this allowed them to continue acting as a social elite long after the economic and political foundations of their ascendancy had been removed.

Global development has, in recent years, been shaped by the rise of transnational capital. This has implications for the quality and effectiveness of those national laws, regulations and policies in place to monitor transnational capital, ensure that multi national organisations assume responsibility and hold them accountable should they fail to do so. In balancing these objectives, contrasting issues come to the fore, such as the fear of capital flight; an issue especially profound in small open economies where the balance may tip in the favour of retaining, as opposed to regulating, foreign capital.
This paper can be considered in three parts. First, the paper addresses the shift in global leadership from national governments to multinational corporations (with particular reference to the rise of the Transnational Capitalist Class). This shift will incorporate the connotations of the Third Way. In considering this ideology, it will propose the Third Way as a transition phase to a stage when government is more the “third wheel” than an equal partner in governance structures. Second, the implications of the changing nature of governance on the capacity of nation states to develop effective laws, regulations and policies is discussed which leads on to the third aspect of the paper which identifies the challenges for governments, business and society in reimagining the governance structure pertaining to law, regulation and policy and the need to reconsider existing structures in light of global shifts in power structures.
A new leadership structure, both within the national and international governance system has far reaching implications. Boundary constraints no longer an issue, the potential for equality and global democracy is huge. Instead, a post recessionary world faces new governance challenges in the shape of; legitimacy; accountability and responsibility. Capitalism has invaded government and the primary challenge will be in avoiding the same issues that have dogged our financial markets for the last number of years. The challenge then to laws, regulations and public policy is huge, especially considering that the governments regulating are smaller than those dictating agenda on a global level

We present results for a suite of 14 three-dimensional, high-resolution hydrodynamical simulations of delayed-detonation models of Type Ia supernova (SN Ia) explosions. This model suite comprises the first set of three-dimensional SN Ia simulations with detailed isotopic yield information. As such, it may serve as a data base for Chandrasekhar-mass delayed-detonation model nucleosynthetic yields and for deriving synthetic observables such as spectra and light curves. We employ aphysically motivated, stochastic model based on turbulent velocity fluctuations and fuel density to calculate in situ the deflagration-to-detonation transition probabilities. To obtain different strengths of the deflagration phase and thereby different degrees of pre-expansion, we have chosen a sequence of initial models with 1, 3, 5, 10, 20, 40, 100, 150, 200, 300 and 1600 (two different realizations) ignition kernels in a hydrostatic white dwarf with a central density of 2.9 × 10 g cm, as well as one high central density (5.5 × 10 g cm) and one low central density (1.0 × 10 g cm) rendition of the 100 ignition kernel configuration. For each simulation, we determined detailed nucleosynthetic yields by postprocessing10 tracer particles with a 384 nuclide reaction network. All delayed-detonation models result in explosions unbinding thewhite dwarf, producing a range of 56Ni masses from 0.32 to 1.11M. As a general trend, the models predict that the stableneutron-rich iron-group isotopes are not found at the lowest velocities, but rather at intermediate velocities (~3000×10 000 km s) in a shell surrounding a Ni-rich core. The models further predict relatively low-velocity oxygen and carbon, with typical minimum velocities around 4000 and 10 000 km s, respectively. © 2012 The Authors.

Psychoanalysis has been widely used to develop our understanding of power in organizations. In this paper, I draw on a case study of a non-profit organization in the field of international development, in order to explore in depth how people engage with powerful discourses at play in this context. I use an ethnographic approach to do so, and find Lacan's ideas on identification and affect to be useful in the analysis of the case. I show how, at first glance, people appeared to readily alter their activities and goals in response to the wishes of an important donor. However, moving deeper to examine identifications on the part of people themselves reveals complex forms of recognition that were inscribed by affective relations. I discuss the implications of these findings for the study of organizations, including the contribution of the concept of affect for studies of identification and subjection in organizations, and the value of ethnographic research approaches that draw upon Lacan's work on recognition.

This article proposes that a complementary relationship exists between the formalised nature of digital loyalty card data, and the informal nature of small business market orientation. A longitudinal, case-based research approach analysed this relationship in small firms given access to Tesco Clubcard data. The findings reveal a new-found structure and precision in small firm marketing planning from data exposure; this complemented rather than conflicted with an intuitive feel for markets. In addition, small firm owners were encouraged to include employees in marketing planning.

Cameron’s flagship policy of the ‘Big Society’ rests on a society/government dichotomy, diagnosing a ‘broken society’ caused by ‘big government’ having assumed the role communities once played. The remedy is greater social responsibility and the ‘Big Society’. This article argues that the dichotomy is
deceptive. We aim to show that the Big Society is big government, as it employs techniques for managing the conduct of individuals and communities such that the mentality of government, far from being removed or reduced, is bettered and made more efficient. To illustrate this, we explore two major initiatives: the National Citizen Service and the Community Resilience programme. These
projects demonstrate how practices of informing and guiding the conduct of individuals both produce agents and normalise certain values, resulting in the population being better known and controlled. Thus, far from lessening government and empowering people, the Big Society extends governmentality
throughout the social body.

A large-scale randomised-controlled trial of reading tutoring in 80 schools in Scotland used the Paired Reading (PR) technique. On long-term evaluation, cross-age PR was significantly better than regular teaching, but same-age was not. On short-term evaluation, PR pupils did significantly better than control pupils in both years, and cross-age and same-age were similarly effective. Low socio-economic pupils, lower reading ability pupils, girls and reading with maths tutoring groups did significantly better. Implementation was good in parts, but some important aspects of technique were rare. Reading gains were significantly greater for those with mistakes about every 2 minutes and those who stopped reading to talk every 5 to 7 minutes. Significant gains in self-esteem were seen in same-age and cross-age groups, and for tutees and tutors, but not for controls. The relationship of achievement gain to quality of technique and socio-emotional gains is discussed, with implications for practice. Copyright © 2011 UKLA.
