Inducing preschool children's emotional eating:relations with parental feeding practices

Background: Children's emotional eating is related to greater body mass index and a less-healthy diet, but little is known about the early development of this behavior. Objective: This study aimed to examine the relations between preschool children's emotional eating and parental feeding practices by using experimental manipulation of child mood and food intake in a laboratory setting. Design: Twenty-five 3–5-y-old children and their mothers sat together and ate a standard meal to satiety. Mothers completed questionnaires regarding their feeding practices. Children were assigned to a control or negative mood condition, and their consumption of snack foods in the absence of hunger was measured. Results: Children whose mothers often used food to regulate emotions ate more cookies in the absence of hunger than did children whose mothers used this feeding practice infrequently, regardless of condition. Children whose mothers often used food for emotion regulation purposes ate more chocolate in the experimental condition than in the control condition. The pattern was reversed for children of mothers who did not tend to use food for emotion regulation. There were no significant effects of maternal use of restriction, pressure to eat, and use of foods as a reward on children's snack food consumption. Conclusions: Children of mothers who use food for emotion regulation consume more sweet palatable foods in the absence of hunger than do children of mothers who use this feeding practice infrequently. Emotional overeating behavior may occur in the context of negative mood in children whose mothers use food for emotion regulation purposes. This trial was registered at clinicaltrials.gov as NCT01122290.

Bilingualism and educational achievement:a study of young bilinguals in Birmingham schools and colleges

This study aimed firstly to investigate current patterns of language use amongst young bilinguals in Birmingham and secondly to examine the relationship between this language use and educational achievement. The research then focussed on various practices, customs and attitudes which would favour the attrition or survival of minority languages in the British situation. The data necessary to address this question was provided by a sample of three hundred and seventy-four 16-19 year olds, studying in Birmingham schools and colleges during the period 1987-1990 and drawn from the main linguistic minority communities in Birmingham. The research methods chosen were both quantitative and qualitative. The study found evidence of ethnolinguistic vitality amongst many of the linguistic minority communities in Birmingham: a number of practices and a range of attitudes indicate that linguistic diversity may continue and that a stable diglossic situation may develop in some instances, particularly where demographical and religious factors lead to closeness of association. Where language attrition is occurring it is often because of the move from a less prestigious minority language or dialect to a more prestigious minority language in addition to pressures from English. The educational experience of the sample indicates that literacy and formal language study are of key importance if personal bilingualism is to be experienced as an asset; high levels of oral proficiency in the L1 and L2 do not, on their own, necessarily correlate with positive educational benefit. The intervening variable associated with educational achievement appears to be the formal language learning process and literacy. A number of attitudes and practices, including the very close associations maintained with some of the countries of origin of the families, were seen to aid or hinder first language maintenance and second language acquisition.

Guiding schools to improved performance using data envelopment analysis:an illustration with data from a local education authority

The educational process is characterised by multiple outcomes such as the achievement of academic results of various standards and non-academic achievements. This paper shows how data envelopment analysis (DEA) can be used to guide secondary schools to improved performance through role-model identification and target setting in a way which recognises the multi-outcome nature of the education process and reflects the relative desirability of improving individual outcomes. The approach presented in the paper draws from a DEA-based assessment of the schools of a local education authority carried out by the authors. Data from that assessment are used to illustrate the approach presented in the paper. (Key words: Data envelopment analysis, education, target setting.)

The Great Slump of 2008–9 and Ukraine's integration with the European Union

For a number of years following the Orange revolution of 2004, Ukraine aspired to join the European Union. Although full integration was never a short-term prospect, European integration, through the Association Agreement and the Deep and Comprehensive Free Trade Area, offers considerable benefits to Ukraine. However, the country was severely affected by the Great Slump of 2008–9 in the global economy, and this profoundly negative experience has shaped Ukrainian domestic and foreign policy in the subsequent period, putting paid to aspirations to EU membership and influencing the Ukrainian government's decision to seek a closer relationship with Russia immediately following the presidential election of 2010. Nevertheless, closer relations with Russia should not adversely affect Ukraine's efforts at EU integration.

The n-tuple network: coping with sub-optimality

The subject of this thesis is the n-tuple net.work (RAMnet). The major advantage of RAMnets is their speed and the simplicity with which they can be implemented in parallel hardware. On the other hand, this method is not a universal approximator and the training procedure does not involve the minimisation of a cost function. Hence RAMnets are potentially sub-optimal. It is important to understand the source of this sub-optimality and to develop the analytical tools that allow us to quantify the generalisation cost of using this model for any given data. We view RAMnets as classifiers and function approximators and try to determine how critical their lack of' universality and optimality is. In order to understand better the inherent. restrictions of the model, we review RAMnets showing their relationship to a number of well established general models such as: Associative Memories, Kamerva's Sparse Distributed Memory, Radial Basis Functions, General Regression Networks and Bayesian Classifiers. We then benchmark binary RAMnet. model against 23 other algorithms using real-world data from the StatLog Project. This large scale experimental study indicates that RAMnets are often capable of delivering results which are competitive with those obtained by more sophisticated, computationally expensive rnodels. The Frequency Weighted version is also benchmarked and shown to perform worse than the binary RAMnet for large values of the tuple size n. We demonstrate that the main issues in the Frequency Weighted RAMnets is adequate probability estimation and propose Good-Turing estimates in place of the more commonly used :Maximum Likelihood estimates. Having established the viability of the method numerically, we focus on providillg an analytical framework that allows us to quantify the generalisation cost of RAMnets for a given datasetL. For the classification network we provide a semi-quantitative argument which is based on the notion of Tuple distance. It gives a good indication of whether the network will fail for the given data. A rigorous Bayesian framework with Gaussian process prior assumptions is given for the regression n-tuple net. We show how to calculate the generalisation cost of this net and verify the results numerically for one dimensional noisy interpolation problems. We conclude that the n-tuple method of classification based on memorisation of random features can be a powerful alternative to slower cost driven models. The speed of the method is at the expense of its optimality. RAMnets will fail for certain datasets but the cases when they do so are relatively easy to determine with the analytical tools we provide.

Trade union policy and new technology: the Civil and Public Services Association

The introduction of a micro-electronic based technology to the workplace has had a far reaching and widespread effect on the numbers and content of jobs. The importance of the implications of new technology were recognised by the trade unions, leading to a plethora of advice and literature in the late 70s and early 80s, notably the TUC 'Technology and Employment ' report. However, studies into the union response have consistently found an overall lack of influence by unions in the introduction of technology. Whilst the advent of new technology has coincided with an industrial relations climate of unprecedented hostility to union activity in the post-war period, there are structural weaknesses in unions in coming to terms with the process of technological change. In particular was the identification of a lack of suitable technological expertise. Addressing itself to this perceived weakness of the union response, this thesis is the outcome of a collaborative project between a national union and an academic institution. The thesis is based on detailed case studies concerning technology bargaining in the Civil Service and the response of the Civil and Public Services Associations (CPSA), the union that represents lower grade white collar civil servants. It is demonstrated that the application of expertise to union negotiators is insufficient on its own to extend union influence and that for unions to effectively come to terms with technology and influence its development requires a re-assessment across all spheres of union activity. It is suggested that this has repercussions for not only the internal organisation and quality of union policy formation and the extent, form and nature of collective bargaining with employer representatives, but also in the relationship with consumer and interest groups outside the traditional collective bargaining forum. Three policy options are developed in the thesis with the 'adversarial' and 'co~operative' options representing the more traditional reactive and passive forms of involvement. These are contrasted with an 'independent participative' form of involvement which was a 'pro-active' policy option and utilised the expertise of the Author in the CPSA's response to technological change.

The control of technological change in the motor industry:a case study

This thesis is based upon a case study of the introduction of automated production technologies at the Longbridge plant of British Leyland in the period 1978 to 1980.The investment in automation was part of an overall programme of modernization to manufacture the new 'Mini Metro' model. In the first Section of the thesis, the different theoretical perspectives on technological change are discussed. Particular emphasis is placed upon the social role of management as the primary controllers of technological change. Their actions are seen to be oriented towards the overall strategy of the firm, integrating the firm's competitive strategy with production methods and techniques.This analysis is grounded in an examination of British Leyland's strategies during the 1970s.. The greater part of the thesis deals with the efforts made by management to secure their strategic objectives in the process of technological change against the conflicting claims of their work-force. Examination of these efforts is linked to the development of industrial relations conflict at Longbridge and in British Leyland as a whole.Emphasis is placed upon the struggle between management in pursuit of their version of efficiency and the trade unions in defence of job controls and demarcations. The thesis concludes that the process of technological change in the motor industry is controlled by social forces,with the introduction of new technologies being closely intertwined with management!s political relations with the trade unions.

Manufacturing process challenges when machining superalloys

The implementation of advanced manufacturing systems with high process capability is an essential requirement for the high value manufacturing industries. To ensure high process capability, industry needs to deal with the requirement for tight tolerances and the unavoidable variations in materials, and manufacturing and inspection processes. In the case of machining superalloys, such variations result in the need to change the machine parameters for producing different batches of materials from different suppliers. This is required in order to get the process under control and reduce waste and defects, leading to better competitiveness. This papers discuss the variability in materials and the corresponding process requirements when machining superalloys, and highlights the impact of metrology in achieving manufacturing process improvement.

Interregionalism

Interregionalism is deeply rooted in the foreign policies and external relations of the EU. Interregional cooperation today not only encompasses trade and aid but also political dialogue, cultural relations and even security cooperation. Although the EU’s official ambition has been to formalize and institutionalize its interregional relations with other regional bodies or organizations (so-called ‘pure interregionalism’), in practice there are a bewildering variety of interregional or group-to-group relations on display (Hänggi 2006; Baert et al. 2014). The EU is rapidly evolving as a global actor and while doing so it has been trying to export its own civilian and normative values. Interregionalism is an important tool in this process, contributing to the EU’s policy of fostering regionalism worldwide, not only in the triad (Europe, North America and East Asia) (De Lombaerde and Schulz 2009). Through interregionalism, the EU and its regional others enhance their presence, gain recognition, tighten institutional cohesion and define identities. Interregionalism, therefore, occupies a special position in the construction of regional actorness in global affairs (Wunderlich 2012). However, the link between interregionalism and regionalism is both complex and underexplored (Baert et al. 2014; Doidge 2007). Much depends on the type of interregional relations, and the balance of other forms of cooperation, which appears to play out differently in different regions. All this leads to a number of research questions that should be addressed by the academic literature, including is there a preference for interregional relations in EU’s foreign policy? If so, for what reason(s)? What are the consequences of such a preference? What is the role of interregionalism in the broader context of EU’s external policies? How are expressions of regionalism related to expressions of interregionalism? Does the sui generis character of the EU lead to a sui generis character of EU interregionalism? This chapter provides a general overview of the evolution of the field, the key conceptual and analytical debates, as well as the main research questions that drive the research agenda. Emphasis is also placed on identifying the main gaps in the field and suggesting directions.
