New Perspectives on Games and Interaction

This volume is a collection of papers presented at the 2007 colloquium on new perspectives on games and interaction at the Royal Dutch Academy of Sciences in Amsterdam. The purpose of the colloquium was to clarify the uses of the concepts of game theory, and to identify promising new directions. This important collection testifies to the growing importance of game theory as a tool to capture the concepts of strategy, interaction, argumentation, communication, cooperation and competition. Also, it provides evidence for the richness of game theory and for its impressive and growing application

Quantification of appetite-regulating hormones in children with hypothalamic and common obesity

Background. Current understanding of the appetite-regulating neuroendocrine circuitry remains incomplete, and efficacious treatments for both common and hypothalamic obesity (HyOb) are lacking. Concurrently, the expanded role of oxytocin (OXT) in energy homeostasis and human behaviour is beginning to be understood. Objectives. To optimise and translate an OXT enzyme immunoassay (EIA) to elucidate whether there were any unique differences in the plasma endocrine milieu in patients with HyOb. Methods. Optimisation work was carried out using EIAs with polyclonal and monoclonal secondary antibodies. Obese (BMI>+2 SDS) and lean (BMI≤+2 SDS) children with (HyOb and HyLean) and without (Ob and Lean) hypothalamic disorders (septo-optic dysplasia or suprasellar tumours) were phenotyped using the Dykens’ Hyperphagia Questionnaire Score (DHQS). Plasma concentrations of leptin, insulin, OXT, BDNF, αMSH, acylated ghrelin, AgRP and copeptin were measured. Results. Solid phase extraction demonstrated markedly variable OXT recovery, and potentially increased rather than decreased interference. A polyclonal secondary antibody-containing EIA showed significant cross-reactivity with several peptides in human plasma compared to a monoclonal secondary antibody-containing EIA. Of the 122 children recruited (50 HyOb, 29 HyLean, 24 Ob, 19 Lean, mean age 11.3±3.9 years) there were no differences in DHQS or hormone concentrations between HyOb and Ob groups. Obesity was associated with compensatorily increased leptin and insulin, and decreased ghrelin and AgRP concentrations. More rapidly increasing BMI was independently associated with a younger age and lower plasma αMSH concentrations. OXT concentrations did not show any correlation with BMI or DHQS. Conclusion. The use of plasma extraction processes and EIAs in the literature needs re-examination. The plasma endocrine milieu in HyOb vs. common obesity does not differ, with a compensatory increase in anorexigens and decrease in orexigens. Lower plasma αMSH was associated with more rapid weight gain, suggesting that MC4R agonists may be a therapeutic option in all forms of obesity

Transition expertise: Cognitive factors and developmental processes that contribute to repeated successful career transitions amongst elite athletes, musicians and business people

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.This thesis examines the nature of transition expertise which enables individuals to make repeated successful transitions over the course of their career. It addressed four areas that contribute to transition expertise: 1) cognitive flexibility that enables the generalisation of expert knowledge and processes; 2) inferential and inductive cognitive mechanisms that enable expertise to be generalised; 3) personal intelligences that are used to support transitions; and 4) practical intelligence as it supports performance contextually during transitions. The study used retrospective interviews to gather data from elite performers in three fields who had made successful career transitions: sports people who become national coaches or heads of national bodies; successful musicians who become heads of faculty or principals of a conservatoire; successful business people who become senior vice presidents or CEOs. Participants were able to generalise expert knowledge and processes beyond their primary domains, contrary to widely held views about the domain specificity of expertise. Cognitive flexibility enabled this generalisation and was developed through broad based training, early exposure to multiple domains and the early use of generative cognitive processes during the development of primary domain expertise. Inductive, inferential and analogical cognitive mechanisms were the main tools through which expertise was generalised during transitions. Personal intelligence contributed to transition expertise. Intrapersonal intelligence enabled individuals to understand how their abilities, values and motivations shaped their career progression. Interpersonal intelligence enabled individuals to respond effectively to the requirements of their peers, direct reports, stakeholders and organisational context. Contrary to expectations, self regulatory processes did not play a central role in the management of transitions. Practical intelligence enabled transition expertise. It involved more than applying subject-area and tacit knowledge. It encompassed the abilities to: identify and resolve problems; manipulate environmental objects in the form of administrative tasks, schedules and plans; utilise resources in terms of people and materials; and shape their environment, corporate structures and culture. Transition expertise develops and evolves over the course of a career as it uses convergent and divergent cognitive processes, inductive mechanisms, personal awareness and cognitive pragmatics to address issues of increasing scope and implication. While motivational factors, self belief and personality resiliency are important contributors to transition expertise they did not form part of this study

Maritime expressions:a corpus based exploration of maritime metaphors

This study uses a purpose-built corpus to explore the linguistic legacy of Britain’s maritime history found in the form of hundreds of specialised ‘Maritime Expressions’ (MEs), such as TAKEN ABACK, ANCHOR and ALOOF, that permeate modern English. Selecting just those expressions commencing with ’A’, it analyses 61 MEs in detail and describes the processes by which these technical expressions, from a highly specialised occupational discourse community, have made their way into modern English. The Maritime Text Corpus (MTC) comprises 8.8 million words, encompassing a range of text types and registers, selected to provide a cross-section of ‘maritime’ writing. It is analysed using WordSmith analytical software (Scott, 2010), with the 100 million-word British National Corpus (BNC) as a reference corpus. Using the MTC, a list of keywords of specific salience within the maritime discourse has been compiled and, using frequency data, concordances and collocations, these MEs are described in detail and their use and form in the MTC and the BNC is compared. The study examines the transformation from ME to figurative use in the general discourse, in terms of form and metaphoricity. MEs are classified according to their metaphorical strength and their transference from maritime usage into new registers and domains such as those of business, politics, sports and reportage etc. A revised model of metaphoricity is developed and a new category of figurative expression, the ‘resonator’, is proposed. Additionally, developing the work of Lakov and Johnson, Kovesces and others on Conceptual Metaphor Theory (CMT), a number of Maritime Conceptual Metaphors are identified and their cultural significance is discussed
