From Negotiations to Accession: Lessons from the 2007 Enlargement

Although overshadowed by the ‘big bang’ enlargement of 2004, the accession of Bulgaria and Romania to the EU in 2007 was more than simply a ‘coda’ enlargement. It had its own distinctive features and provides important insights into how the EU’s handling of enlargement is evolving. It established a number of interesting and potentially significant precedents and provided timely reminders of how important political and public opinion can be for ratification. Examination of the period from negotiating the terms of membership to the actual accession of the two applicants underlines the dynamic and increasingly uncertain nature of the EU enlargement process.

Bridging and Linking in a Divided Society: A Social Capital Case Study from Northern Ireland

This paper reports the results of research into social capital levels in the Central Housing Community Network, part of the community consultation structure of the Northern Ireland Housing Executive. Membership of the forum increased the bonding, bridging and linking social capital of its members and appeared to improve community relations, although that was not its stated purpose. However, the empirical link between social capital and the quality of community relations remains unproven. The research provides an example of the state creating a positive space for interaction with civil society through consultation on service delivery issues. In an international policy environment where ‘mixed’ communities are the ideal, the potential of service-based forums to contribute to community cohesion may have been underestimated.

And We’d Like to Thank…::Romania’s Integration into the European Union, 1989-2007

Conditionality is formally a key determinant of many non-member states’ relations with the EU. It is particularly so for states intent on membership. As the case of Romania shows, the EU’s use of conditionality is far from consistent. Relations can develop and accession take place without the requisite conditions being met. This follows from the use the EU makes of the flexibility evident in its evolving and generally vague definitions of the conditions that need to be met. Hence it was often extraneous factors over which Romania had either limited or no influence that were responsible for key developments in relations. These factors include the geopolitical and strategic interests of the EU and its member states, the actions of the Commission and the agenda-setting and constraining effects of rhetorical commitments and timetables, and the dynamics of the EU’s evolving approach to eastern enlargement.

Continuity and Change in the European Union’s Approach to Enlargement::Turkey and Central and Eastern Europe compared

Existing studies of European Union (EU) enlargement provide few answers to questions concerning continuity and change in the dynamics of the process. This article identifies a number of conditioning factors that have shaped the EU’s approach to eastern enlargement and traces elements of continuity and change in the EU’s handling of Turkey’s membership aspirations. The article focuses on three established factors – member state preferences, supranational activism and EU capacity – and two less prominent factors – public opinion and narrative frame

Predicting Cell Cycle Regulated Genes by Causal Interactions

The fundamental difference between classic and modern biology is that technological innovations allow to generate high-throughput data to get insights into molecular interactions on a genomic scale. These high-throughput data can be used to infer gene networks, e. g., the transcriptional regulatory or signaling network, representing a blue print of the current dynamical state of the cellular system. However, gene networks do not provide direct answers to biological questions, instead, they need to be analyzed to reveal functional information of molecular working mechanisms. In this paper we propose a new approach to analyze the transcriptional regulatory network of yeast to predict cell cycle regulated genes. The novelty of our approach is that, in contrast to all other approaches aiming to predict cell cycle regulated genes, we do not use time series data but base our analysis on the prior information of causal interactions among genes. The major purpose of the present paper is to predict cell cycle regulated genes in S. cerevisiae. Our analysis is based on the transcriptional regulatory network, representing causal interactions between genes, and a list of known periodic genes. No further data are used. Our approach utilizes the causal membership of genes and the hierarchical organization of the transcriptional regulatory network leading to two groups of periodic genes with a well defined direction of information flow. We predict genes as periodic if they appear on unique shortest paths connecting two periodic genes from different hierarchy levels. Our results demonstrate that a classical problem as the prediction of cell cycle regulated genes can be seen in a new light if the concept of a causal membership of a gene is applied consequently. This also shows that there is a wealth of information buried in the transcriptional regulatory network whose unraveling may require more elaborate concepts than it might seem at first.

Is low self-esteem an inevitable consequence of stigma? An example from women with chronic mental health problems

It is often assumed that membership in a stigmatized group has negative consequences for the self-concept. However, this relationship is neither straightforward nor inevitable, and there is evidence suggesting that negative consequences may not necessarily occur (Psychol. Rev. 96(4) (1989) 608). This paper argues that the relationship has not been sufficiently theorized, and that a more detailed analysis is called for in order to understand the relationship between stigma and the self. The paper presents a critical examination of modified labeling theory (Am. Sociol. Rev. 52 (1987) 96), with examples from a study examining perceptions of stigma and their relationship to self-evaluation in women with chronic mental health problems. Open-ended interviews and qualitative analyses were used in preference to global measures of self-esteem. It was found that although the women were aware of society's unfavorable representations of mental illness, and the effects this had on their lives, they did not accept these representations as valid and therefore rejected them as applicable to the self. The participants did not deny their mental health problems, but their acceptance of labels was critical and pragmatic. Labels were rejected when they were perceived as carrying an unrealistic and negative stereotype, or when the women felt that their symptoms did not fit with the diagnostic criteria. The research illustrates the importance of considering people's subjective understandings of stigmatized conditions and societal reactions in order to understand the relation between stigma and the self.

Cost performance of Irish credit unions

There are 424 credit unions in Ireland with assets under their control of €14.3bn and a membership of 2.5m which equates to about 66% of the economically active population, the highest penetration level of any country. That said, the Irish movement sits at a critical development stage, well behind mature markets such as Canada and the US in terms of product provision, technological sophistication, fragmentation of trade bodies and regulatory environment. This study analyses relative cost efficiency or performance of Irish credit unions using the popular frontier approach which measures an entity’s efficiency relative to a frontier of best practice. Parametric techniques are utilised, with variation in inefficiency being attributed to credit union-specific factors. The stochastic cost frontier parameters and the credit-union specific parameters are simultaneously estimated to produce valid statistical inferences. The study finds that the majority of Irish credit unions are not operating at optimal levels. It further highlights the factors which drive efficiency variation across credit unions and they include technological sophistication, ‘sponsor donated’ resources, interest rate differentials and the levels of bad debt written off

Gender Diversity in the FTSE 100: The Business Case Claim Explored

This article examines the debate within corporate governance about the
appointment of female non-executive directors (NEDs). The first part
tracks the diversity story that corporate governance tells about itself from
the Cadbury Report (1992) to the Davies Report (2011). The second sets
out the evidence used to support the argument that female appointments
enhance profits and corporate profile. The third part presents the
authors' empirical analysis of FTSE 100 companies and female non-
executive board membership, and concludes that there is little evidence
that companies with female board membership display different charac-
teristics from those without. Industry sector emerges as a significant
factor in female appointments. The idea that women should be appointed
to boards to increase corporate profitability and profile is not strongly
supported by this analysis.A social justice argument based upon the right
of woman to equal economic participation opportunities provides a much
superior articulation of the need for boardroom diversity.

Credit Unions in Great Britain: Recent Trends and Current Prospects

Against the current backdrop of deteriorating economic and financial conditions we consider recent trends and current prospects for credit unions in Great Britain. We note that although credit unions have experienced solid membership and asset growth there are clouds on the horizon. Bad debts and loan arrears are on the rise and may be linked to recent legislative amendments and the increasing use by Government of credit unions as a mechanism to achieve its financial inclusion goals. Whatever the reason, the deterioration in the loan book needs to be quickly addressed, or it will ultimately result in either more government bailouts or a stream of failing credit unions.

Dynamic evolution of the genetic search region through fuzzy coding

A technique for automatic exploration of the genetic search region through fuzzy coding (Sharma and Irwin, 2003) has been proposed. Fuzzy coding (FC) provides the value of a variable on the basis of the optimum number of selected fuzzy sets and their effectiveness in terms of degree-of-membership. It is an indirect encoding method and has been shown to perform better than other conventional binary, Gray and floating-point encoding methods. However, the static range of the membership functions is a major problem in fuzzy coding, resulting in longer times to arrive at an optimum solution in large or complicated search spaces. This paper proposes a new algorithm, called fuzzy coding with a dynamic range (FCDR), which dynamically allocates the range of the variables to evolve an effective search region, thereby achieving faster convergence. Results are presented for two benchmark optimisation problems, and also for a case study involving neural identification of a highly non-linear pH neutralisation process from experimental data. It is shown that dynamic exploration of the genetic search region is effective for parameter optimisation in problems where the search space is complicated.

Kin discriminators in the eusocial sweat bee Lasioglossum malachurum: the reliability of cuticular and Dufour's gland odours

The ability to discriminate degrees of relatedness may be expected to evolve if it allows unreciprocated altruism to be preferentially directed towards kin (Hamilton in J Theor Biol 7:1-16, 1964). We explored the possibility of kin recognition in the primitively eusocial halictid bee Lasioglossum malachurum by investigating the reliability of worker odour cues that can be perceived by workers to act as indicators of either nest membership or kinship. Cuticular and Dufour's gland compounds varied significantly among colonies of L. malachurum, providing the potential for nestmate discrimination. A significant, though weak, negative correlation between chemical distance and genetic relatedness (r = -0.055, p

Internet banking and Irish credit unions

The purpose of this paper is to examine IT adoption by Irish credit unions. Using probabilistic models, we explore one aspect of IT, that of internet banking technology, and assess the degree to which characteristics specific to the credit union and to its potential membership base influence adoption. Our
analysis suggests that asset size, organisational structure being a member of the Irish League of Credit Unions and the loan to asset ratio are all important credit union specific drivers of internet banking adoption. We also find that characteristics of the area from where the credit union captures its members are important. Factors such as the percentage of the population that is employed, the proportion of the population in the age bracket 35 to 44, the proportion of the population that have access to broadband and the level of familiarity with a local ATM facility are all identified as influencing the probability of adopting internet banking.

Self-esteem and self-efficacy: Associations with alcohol consumption in a sample of adolescents in Northern Ireland

Cross-sectional and longitudinal studies have reported equivocal findings regarding the association between self-esteem, self-efficacy and adolescent alcohol use. Data were collected from a sample of 11-16-year olds in Northern Ireland (n = 4088) over two consecutive academic years measuring global self-esteem, academic, social and emotional self-efficacy and alcohol involvement. Results showed a domain-specific association between alcohol involvement and self-efficacy, with more problematic alcohol use associated with higher social self-efficacy but lower emotional and academic self-efficacy. Additionally, regression analyses revealed that all self-concept measures significantly predicted drinking group membership. The results are discussed in terms of reported drinking behaviour, interventions with adolescent groups and general development.

Stellar rotation in the Hyades and Praesepe: gyrochronology and braking time-scale

We present the results of photometric surveys for stellar rotation in the Hyades and in Praesepe, using data obtained as part of the SuperWASP exoplanetary transit-search programme. We determined accurate rotation periods for more than 120 sources whose cluster membership was confirmed by common proper motion and colour-magnitude fits to the clusters' isochrones. This allowed us to determine the effect of magnetic braking on a wide range of spectral types for expected ages of ˜600 Myr for the Hyades and Praesepe. Both clusters show a tight and nearly linear relation between J-Ks colour and rotation period in the F, G and K spectral range. This confirms that loss of angular momentum was significant enough that stars with strongly different initial rotation rates have converged to the same rotation period for a given mass, by the ages of Hyades and Praesepe. In the case of the Hyades, our colour-period sequence extends well into the M dwarf regime and shows a steep increase in the scatter of the colour-period relation, with identification of numerous rapid rotators from ˜0.5 Msun down to the lowest masses probed by our survey (˜0.25 Msun). This provides crucial constraints on the rotational braking time-scales and further clears the way to use gyrochronology as an accurate age measurement tool for main-sequence stars.

On the parallax of WD 0346+246: a halo white dwarf candidate

We present a parallax measurement for the very cool degenerate WD 0346+246, the serendipitous discovery of which was reported by Hambly et al, We find an absolute parallax of 36 +/- 5 mas, yielding a distance estimate of 28 +/- 4pc. The resulting absolute visual magnitude of the object is M-V = 16.8 +/- 0.3, making it the second-lowest luminosity white dwarf currently known. We use the distance estimate and measured proper motion to show that the object has kinematics consistent with membership of the Galactic halo. WD 0346+246 is therefore by far the coolest and least luminous of only a handful of plausible halo white dwarf candidates. As such, the object has relevance to the ongoing debate concerning the results of microlensing experiments and the nature of any baryonic dark matter component to the Galactic halo residing in stellar remnants.
