The demography of Tristan da Cunha

Abstract The eruption of the volcano on Tristan da Cunha in 1961 and the subsequent arrival of the island population in the United Kingdom provided a unique opportunity for studying the health of this formerly isolated community. During their stay, while the facilities and services of modern medicine were made available to them, investigations of many facets of their general biology were made under the auspices of the Medical Research Council, co-ordinated by Dr. H. E. Lewis. Analysis of their demographic history was essential to understand many features of their disease pattern, and the results of this analysis are presented here. They are of interest in that they not only show some consistent trends in the common variables of demography, but also demonstrate biological principles, some perhaps for the first time in man, which may be fundamental in the process of colonization as a biological phenomenon, e.g. the initial difficulty of establishment of a population in a new area, the curious demographic structure that may emerge in its earliest years, the bottleneck effect of population-size reduction, the founder principle.     

TREATING CONDUCT-DISORDERED ADOLESCENTS AND YOUNG ADULTS BY WORKING WITH THE PARENTS

A method of therapy for families with an acting out adolescent or young adult is presented, as is a rationale for the method. The aim of the approach is to alter the underlying problem of immaturity that is hypothesized to exist in these families. Emphasis is placed on working with the parents in a systematic way over an extended period of time. As progress is made by the parents, an emotional crisis is created in the adolescent that can then be used by him as the basis for extensive change. The therapy of the parents proceeds in phases: 1) preparation for a long-term effort; 2) rethinking and objectively evaluating the nature of the relationship with the adolescent in specific areas; 3) translation of the newly gained perspective into action positions vis-à-vis the adolescent; and 4) non-child-focused therapy.     

Treatment of incarcerated, sexually-abused adolescent females: an outcome study

This study examined the psychosocial functioning of 100 adolescent females (ages 12-17) sentenced to secure care in a southeastern state and the impact of gender-specific, cognitive-behavioral therapy (CBT) intervention on the psychosocial functioning of subjects who reported a history of sexual abuse. The Multidimensional Adolescent Assessment Scale (MAAS) was used to assess psychosocial functioning. Pre-test scores on the MAAS revealed significantly higher scores on 12 of 16 dimensions of psychosocial functioning and higher rates of serious criminal behavior for youth who subsequently disclosed sexual abuse histories as compared to those without such histories. At post-test, statistically significant improvements in psychosocial functioning were observed on 14 of 16 MAAS subscales for those who received the CBT intervention. Thus, incarcerated female adolescents who reported a history of sexual abuse demonstrated more impairment in their functioning as compared to those without a reported history of sexual abuse and responded positively to gender-specific, CBT-based intervention.     

Applying the ‘comply-or-explain’ principle: discursive legitimacy tactics with regard to codes of corporate governance

The comply-or-explain principle is a central element of most codes of corporate governance. Originally put forward by the Cadbury Committee in the UK as a practical means of establishing a code of corporate governance whilst avoiding an inflexible “one size fits all” approach, it has since been incorporated into code regimes around the world. Companies can either comply with code provisions or may explain why they do not comply, i.e., why they deviate from a code provision. Despite its wide application very little is known about the ways in which comply-or-explain is used. In addressing this we employ legitimacy theory by which explanations for deviating can be understood as means of legitimizing the company’s actions. We analyzed the compliance statements and reports of 257 listed companies in the UK and Germany, producing some 715 records of deviation. From this we generated an empirically derived taxonomy of the explanations. In a second order analysis we examine the underlying logic and identify various legitimacy tactics. We discuss the consequences of these legitimacy tactics for code regimes and the implications for policy makers.     

A Generic Semantic Grammar for Quantitative Text Analysis: Applications to East and West Berlin Radio News Content from 1979

In a semantic text analysis the researcher begins by creating one of two types of semantic grammars, each of which provides one or more templates that specify the ways concepts (or more general themes) may be related. On the one hand, a phenomenal semantic grammar can be created to extract phenomenon-related information from a text population (e.g., "Among the population's grievances [the phenomenon of interest in this case], which were ones for the abolition of taxes?"). On the other hand, a generic semantic grammar may be developed to yield data about the text population itself (e.g., "Among all clauses in the text population, how many were grievances for the abolition of taxes?"). This paper describes a generic semantic grammar that can be used to encode themes and theme relations in every clause within randomly sampled texts. Unlike the surface-grammatical relations mapped by syntax grammars, the theme relations allowed in this grammar only permit unambiguous encoding according to the meanings that clauses were intended to convey within their social context. An application of the grammar provides a concrete illustration of its research potential.     

Bayesian Nonparametric Hidden Markov Models with application to the analysis of copy-number-variation in mammalian genomes

We consider the development of Bayesian Nonparametric methods for product partition models such as Hidden Markov Models and change point models. Our approach uses a Mixture of Dirichlet Process (MDP) model for the unknown sampling distribution (likelihood) for the observations arising in each state and a computationally efficient data augmentation scheme to aid inference. The method uses novel MCMC methodology which combines recent retrospective sampling methods with the use of slice sampler variables. The methodology is computationally efficient, both in terms of MCMC mixing properties, and robustness to the length of the time series being investigated. Moreover, the method is easy to implement requiring little or no user-interaction. We apply our methodology to the analysis of genomic copy number variation.     

Financial assistance for families with severely disabled children and transport costs

Families with severely disabled children encounter many difficulties in getting out and about. The inadequacy of statutory financial assistance for transport related costs is confirmed by an analysis of families receiving grants from the Family Fund Trust. A third of the sample of 37 000 families with a severely disabled child, received grants for transport related costs. Such grants were more common for families with very young disabled children, children with particular diagnoses, or severely impaired motor function, sight and speech, and families whose children were dependent on technology, or who subsequently died. Recommendations for improving current statutory support are made. Copyright © 1999 John Wiley & Sons, Ltd.     

Thirty‐five Years Later in Development Assistance: Have We Moved On,or Just Performed a Minuet?

Development economists have presented the problems of development in varying and incompatible terms, and have influentially advocated contradictory policies. After twists and turns a broad consensus has emerged on pro‐poor growth objectives and on the policy and institutional means of achieving them. But a number of important questions remain unresolved or indeterminate. Development experts, economists and others, should have the humility to recognise the country specificity of much development experience and the multiplicity of valid paths to the goal of material wellbeing. They are least likely to mislead if their advice acknowledges the likely joint importance of macroeconomic stability, reasonably efficient markets, and supportive institutions.     

Problems of Growth in a High Technology Firm: Moving between Conscious and Unconscious Accounts of Organizational Processes

This paper explores an infrequently discussed methodological divide within qualitative research; that between conscious and unconscious accounts of organizational processes. The paper makes use of an empirical case study of problems encountered in the growth of a high-technology company. The conscious accounts of growth treat members of the firm as knowledgeable agents whose understandings are then drawn upon to generate an account of growth in terms of interrelated processes of power, meaning and legitimacy. These conscious accounts are then complemented through an exploration of unconscious dynamics in the personality of the entrepreneur, the work group and the `family' structure of the firm. It is argued that the key shift in moving between conscious and unconscious interpretation, involves the bracketing of the reality claims implicit in conscious rationalizations, and a re-listening to research material as a largely unconscious projection of individuals' `inner worlds'. With unconscious interpretations, the character of language, its emotional content and in particular the sources of individual and group anxiety all realize a central importance. Despite the established divide in the literature between these two forms of interpretation, it is argued that the case suggests the value and necessity of their integration, particularly for the understanding of creativity.
