What can interdisciplinarity offer to policy problems? Understanding the public policy of obesity

In the UK academics are being urged to embrace interdisciplinarity in their research and teaching activities. In the case of public policy, there is a tension between the epistemological formations from the parent discipline of politics and garnering the benefits of interdisciplinarity. Furthermore, interdisciplinarity in public policy cannot and should not ignore cleavages in existing policy pathways. These concerns are discussed in the article by assessing the public policy of obesity in England and Wales.

Expropriation of minority shareholders and payout policy

This paper studies the payout policy of Italian firms controlled by large majority shareholders (controlled firms). The paper reports that a firm’s share of dividends in total payout (dividends plus repurchases) is negatively related to the size of the cash flow stake of the firm’s controlling shareholder and positively associated with the wedge between the controlling shareholder’s control rights and cash flow rights. These findings are consistent with the substitute model of payout. One of the implications of this model is that controlled firms with weak corporate governance set-ups, in which controlling shareholders have strong incentives to expropriate minority shareholders, tend to prefer dividends over repurchases when disgorging cash.

An analysis of costs in institutions of higher education in England

Cost functions are estimated, using random effects and stochastic frontier methods, for English higher education institutions. The article advances on existing literature by employing finer disaggregation by subject, institution type and location, and by introducing consideration of quality effects. Estimates are provided of average incremental costs attached to each output type, and of returns to scale and scope. Implications for the policy of expansion of higher education are discussed.

The French Confederation Generale du Travail and the International Secretariat of National Trade Union Centres (1900-1914):French syndicalist attitudes towards internationalism and the International Labour Movement

This thesis examines relations between the French Confederation Generale du Travail (CGT) and the labour movements of other countries in the years leading up to the First World War. The aim of the study is to examine the CGT's policy of internationalism in practice, both in relations with other labour movements and in its membership of the International Secretariat of National Trade Union Centres (between 1900 and 1914). In particular, the relationship between the French and German labour movements is explored in the light of the events of August 1914. This study shows that the relationship was a reflection of the respective positions of the French and German labour movements in the international movement. It also subjects to close scrutiny the assumption, widely made before 1914, that workers had more in common with each other than with the ruling classes of their own country, by analysing the extent of, and the reasons for internationalism and international cooperation in the labour movement. As a study of the International Secretariat of National Trade Union Centres, an organisation about which very little has previously been written, this thesis complements existing work on the international labour movement prior to 1914. It also provides new insights into the French CGT by concentrating on the fundamental areas of internationalism and opposition to war, and offers fresh contributions to the continuing debate on the international labour movement and its response to the outbreak of war.

The management of diversification in a large industrial company

This work is the result of an action-research-type study of the diversification effort of part of a major U.K. industrial company. Work in contingency theory concerning the impact of environmental factors on organizational design, and the systemic model of viable systems put forward by Stafford Beer form the theoretical basis of the vvork. The two streams of thought are compared and found to offer similar conclusions about the design of effective organizations. These findings are taken as the framework for an analysis both of organization structures for promoting innovation described in the literature, and of those employed by the company for this purpose in recent years. Much attention is given to the use of venture groups, and conclusions are drawn on particular factors which may influence their success or failure. Both theoretical considerations, and the examination of the company' s recent experience suggested that the formation of the policy of diversification, as well as the method of implementation of the police, might affect its outcorre. Attention is therefore focused on the policy-making and planning process, and in particular on possible problems that this process could generate in a multi-division company. The view finally taken of diversification effort is that it should be regarded as a learning system. This view helps to expose some ambiguities in the concepts of success and failure in this area, and demonstrates considerable weaknesses in traditional project evaluation procedures.

The effect of social influence and curfews on civil violence

We investigate the policies of (1) restricting social influence and (2) imposing curfews upon interacting citizens in a community. We compare and contrast their effects on the social order and the emerging levels of civil violence. Influence models have been used in the past in the context of decision making in a variety of application domains. The policy of curfews has been utilised with the aim of curbing social violence but little research has been done on its effectiveness. We develop a multi-agent-based model that is used to simulate a community of citizens and the police force that guards it. We find that restricting social influence does indeed pacify rebellious societies, but has the opposite effect on peaceful ones. On the other hand, our simple model indicates that restricting mobility through curfews has a pacifying effect across all types of society.

Intrapartum tests for group B streptococcus:accuracy and acceptability of screening

Objective: To assess the accuracy and acceptability of polymerase chain reaction (PCR) and optical immunoassay (OIA) tests for the detection of maternal group B streptococcus (GBS) colonisation during labour, comparing their performance with the current UK policy of risk factor-based screening. Design Diagnostic test accuracy study. Setting and population Fourteen hundred women in labour at two large UK maternity units provided vaginal and rectal swabs for testing. Methods The PCR and OIA index tests were compared with the reference standard of selective enriched culture, assessed blind to index tests. Factors influencing neonatal GBS colonisation were assessed using multiple logistic regression, adjusting for antibiotic use. The acceptability of testing to participants was evaluated through a structured questionnaire administered after delivery. Main outcome measures The sensitivity and specificity of PCR, OIA and risk factor-based screening. Results Maternal GBS colonisation was 21% (19-24%) by combined vaginal and rectal swab enriched culture. PCR test of either vaginal or rectal swabs was more sensitive (84% [79-88%] versus 72% [65-77%]) and specific (87% [85-89%] versus 57% [53-60%]) than OIA (P <0.001), and far more sensitive (84 versus 30% [25-35%]) and specific (87 versus 80% [77-82%]) than risk factor-based screening (P <0.001). Maternal antibiotics (odds ratio, 0.22 [0.07-0.62]; P = 0.004) and a positive PCR test (odds ratio, 29.4 [15.8-54.8]; P <0.001) were strongly related to neonatal GBS colonisation, whereas risk factors were not (odds ratio, 1.44 [0.80-2.62]; P = 0.2). Conclusion Intrapartum PCR screening is a more accurate predictor of maternal and neonatal GBS colonisation than is OIA or risk factor-based screening, and is acceptable to women. © RCOG 2010 BJOG An International Journal of Obstetrics and Gynaecology.

Driving licensing renewal policy using neural network-based probabilistic decision support system

This paper investigates neural network-based probabilistic decision support system to assess drivers' knowledge for the objective of developing a renewal policy of driving licences. The probabilistic model correlates drivers' demographic data to their results in a simulated written driving exam (SWDE). The probabilistic decision support system classifies drivers' into two groups of passing and failing a SWDE. Knowledge assessment of drivers within a probabilistic framework allows quantifying and incorporating uncertainty information into the decision-making system. The results obtained in a Jordanian case study indicate that the performance of the probabilistic decision support systems is more reliable than conventional deterministic decision support systems. Implications of the proposed probabilistic decision support systems on the renewing of the driving licences decision and the possibility of including extra assessment methods are discussed.
