    This thesis examines the labour supply of older workers, their movement into retirement, and any movement out of retirement and back into work. In particular the labour force participation, labour supply and wage elasticity and other income elasticity of work hours are estimated for older workers and compared to younger workers. The thesis goes on to look at the movement into retirement for older workers as a whole by examining cohorts by gender, wave and age. The thesis also presents a descriptive and quantitative • examination of the changes in income and happiness that occur as an individual retires. Finally the thesis examines the reasons why an individual may return to work from v . retirement. The results of the findings suggest: that younger workers are significantly more responsive to wage and household income changes than older worker

    Self-help/mutual aid groups in mental health : ideology, helping mechanisms and empowerment

    Get PDF
    In the last quarter of the twentieth century, self-help/mutual aid groups for mental health issues started to emerge in growing numbers, mainly in Western societies, offering and/or advocating for alternative non-traditional forms of support, and attracted the attention of many researchers and clinicians for their unique characteristics. Among the subjects of interest are typologies of groups, helping mechanisms and benefits from participation. However, there is lack of systematic research in the area and existing studies have been largely confined to the therapeutic value of these groups instead of acknowledging their socio-political meaning and subsequent psychosocial benefits for their members like personal empowerment. The present study was conducted during the transitional years from a Conservative to a newly elected Labour Government (1996 -1998), with subsequent policy shifts taking place in the welfare sector. The purpose of the study was to explore the potential of self-help groups as part of a broader new social movement, the service user movement, focussing on the English scene. It addressed this issue examining the relevance of a group typology based on political ideology and focus of change. To test the validity of this classification for members, a set of individual characteristics and group mechanisms as well as their change through time were examined. The sample consisted of fourteen mental health selfhelp/mutual aid groups from London and South East England, with a variety of structural and organisational features. The methodology used was a combination of both quantitative (self-completion questionnaires) and qualitative techniques (analysis of written material, participant observation and interviews). Measurements were repeated after a one-year interval (Time 1N=67, Time 2 N=56). Findings showed that, indeed, political ideology of self-help/mutual aid groups provided the basis of a meaningful typology and constitutes a comprehensive way of categorising them. Group ideology was related to specific helping mechanisms and aspects of personal empowerment. Specifically, conservative and combined group members reported more expressive group processes like sharing of feelings and self-disclosure, while radical group members were more empowered and optimistic. Group identification was also associated with specific helping activities and aspects of empowerment in the three group categories. The psychosocial character of group types and the beneficial outcomes for members remained stable through time. In general, prolonged participation was reflected in greater member identification with the group and resulted in improved mental wellbeing, increased social support, companionship and optimism for the future

    Studies of strategic performance management for classical organizations theory & practice

    Get PDF
    Nowadays, the activities of "Performance Management" have spread very broadly in actually every part of business and management. There are numerous practitioners and researchers from very different disciplines, who are involved in exploring the different contents of performance management. In this thesis, some relevant historic developments in performance management are first reviewed. This includes various theories and frameworks of performance management. Then several management science techniques are developed for assessing performance management, including new methods in Data Envelopment Analysis (DEA) and Soft System Methodology (SSM). A theoretical framework for performance management and its practical procedures (five phases) are developed for "classic" organizations using soft system thinking, and the relationship with the existing theories are explored. Eventually these results are applied in three case studies to verify our theoretical development. One of the main contributions of this work is to point out, and to systematically explore the basic idea that the effective forms and structures of performance management for an organization are likely to depend greatly on the organizational configuration, in order to coordinate well with other management activities in the organization, which has seemingly been neglected in the existing literature of performance management research in the sense that there exists little known research that associated particular forms of performance management with the explicit assumptions of organizational configuration. By applying SSM, this thesis logically derives some main functional blocks of performance management in 'classic' organizations and clarifies the relationships between performance management and other management activities. Furthermore, it develops some new tools and procedures, which can hierarchically decompose organizational strategies and produce a practical model of specific implementation steps for "classic" organizations. Our approach integrates popular types of performance management models. Last but not least, this thesis presents findings from three major cases, which are quite different organizations in terms of management styles, ownership, and operating environment, to illustrate the fliexbility of the developed theoretical framework

    The Influence of Quality on eWOM: A Digital Transformation in Hotel Management

    Get PDF
    612324There is no doubt that the use of Internet for purchasing products and services has constituted a crucial change in how people go about buying them. In the era of digital transformation, the possibility of accessing information provided by other users about their personal experiences has taken on more weight in the selection and buying processes. On these lines, traditional word-of-mouth (WOM) has given way to electronic word-of-mouth (eWOM), which constitutes a major social change. This behavior is particularly relevant in the services area, where potential users cannot in advance assess what is on offer. There is an abundant literature analyzing the effects of eWOM on different variables of interest in this sector. However, little is known about the factors that determine eWOM. Thus, the main objective of the present paper is to analyze the impact of two variables (objective quality and perceived quality) on eWOM. Both of them are crucial for potential customers in the process of finding hotel accommodations and they can motivate people to make such comments. The results demonstrate that these variables truly have a significant impact on whether or not users make comments on line. Moreover, it proved possible to observe certain differences according to the profile of the tourist involved and the destination where the hotel is located. In the current changing environment, this information is of great use for hotel managers in order to design strategies according to the type of guest they wish to attract.S

    Facial expression recognition and intensity estimation.

    Doctoral Degree. University of KwaZulu-Natal, Durban.Facial Expression is one of the profound non-verbal channels through which human emotion state is inferred from the deformation or movement of face components when facial muscles are activated. Facial Expression Recognition (FER) is one of the relevant research fields in Computer Vision (CV) and Human-Computer Interraction (HCI). Its application is not limited to: robotics, game, medical, education, security and marketing. FER consists of a wealth of information. Categorising the information into primary emotion states only limit its performance. This thesis considers investigating an approach that simultaneously predicts the emotional state of facial expression images and the corresponding degree of intensity. The task also extends to resolving FER ambiguous nature and annotation inconsistencies with a label distribution learning method that considers correlation among data. We first proposed a multi-label approach for FER and its intensity estimation using advanced machine learning techniques. According to our findings, this approach has not been considered for emotion and intensity estimation in the field before. The approach used problem transformation to present FER as a multilabel task, such that every facial expression image has unique emotion information alongside the corresponding degree of intensity at which the emotion is displayed. A Convolutional Neural Network (CNN) with a sigmoid function at the final layer is the classifier for the model. The model termed ML-CNN (Multilabel Convolutional Neural Network) successfully achieve concurrent prediction of emotion and intensity estimation. ML-CNN prediction is challenged with overfitting and intraclass and interclass variations. We employ Visual Geometric Graphics-16 (VGG-16) pretrained network to resolve the overfitting challenge and the aggregation of island loss and binary cross-entropy loss to minimise the effect of intraclass and interclass variations. The enhanced ML-CNN model shows promising results and outstanding performance than other standard multilabel algorithms. Finally, we approach data annotation inconsistency and ambiguity in FER data using isomap manifold learning with Graph Convolutional Networks (GCN). The GCN uses the distance along the isomap manifold as the edge weight, which appropriately models the similarity between adjacent nodes for emotion predictions. The proposed method produces a promising result in comparison with the state-of-the-art methods.Author's List of Publication is on page xi of this thesis

    M-24609-2013Since 1975 the FUNDACIÓN MAPFRE has involved itself in activities serving the general interests of society in different areas of business and culture along with activities aimed at improving the economic and social conditions of the least advantaged members and sectors of society. Within this framework, the FUNDACIÓN MAPFRE’s Institute of Insurance Science promotes and undertakes educational and research activities in the fields of insurance and risk management. In the area of education, its activities include specialized, post-graduate academic training carried out in association with the Pontifical University of Salamanca and courses and seminars for professionals held in Spain and Latin America. These activities have been expanded into other geographic regions thanks to cooperation with a series of institutions in Spain and other countries and an Internet training programme. The Institute offers grants for research in risk and insurance science and operates a specialized insurance and risk management Documentation Centre as support for its activities. The Institute routinely sponsors and draws up reports and publishes books dealing with insurance and risk management to improve our understanding of these fields. Some are intended as reference materials for those starting out in the study or practice of insurance affairs, while others are intended as information sources for undertaking research into specialized issues in greater depth. One of these activities is the publication of this volume, the outcome of research carried out by Drs. Pérez Carrillo and Cuypers in 2011 and 2012, under the guidance of José Antonio Aventín Arroyo

    A bibliometric review on the implications of renewable offshore marine energy development on marine species

    Get PDF
    The growing global demand for sustainable and environmentally friendly energy has stimulated the rapid adoption of renewable offshore energy. However, infrastructure needed for green energy production ironically impacts upon marine species and biodiversity. Consequently, this positional review paper seeks to comprehensively synthesise the prevailing body of knowledge on the impact of offshore energy development on a broad range of marine species. An interpretivist philosophical stance and inductive reasoning was adopted using scientometric analysis to conduct a rich synthesis of extant literature. From an operational perspective, the Scopus database was utilised to search for key terms on the phenomena under investigation and using the VoS Viewer software for the identification of trends using scientometric maps. The analysis reveals that research in this area of science has increased significantly over the last decade but private sector involvement is conspicuous by its absence. Primary concerns among the research community include the impact of energy development on the abundance of species, pollution and biodiversity behaviour and migration. At present, researchers have extensively focused on the impact of offshore wind farms on fish and marine mammals. However, the literature reveals no significant long-term impact upon energy development on most marine species albeit, short-term interference has raised concerns (from sound, disruption of navigation and foraging patterns, and damage of habitat). To minimise short term disruption, researchers have recommended the use of acoustic deterrence during construction, enforcement of protected areas and continued research

    Mandatory detention and treatment of drug users in Malaysia : The implications for the principles of human rights

    The research framework is founded upon a critical analysis of the extent to which the legal process involved in the mandatory treatment and rehabilitation of drug users in Malaysia is consistent with the principles of human rights according to the national and international human rights instruments; the Malaysian Constitution and the UDHR respectively. The mandatory treatment is based upon the principles of punishment rather than rehabilitation. The arrest and detention of these drug users, which are salient features of the legal process raises the issue of serious violations of the human rights principles. To fulfill the true objective of the government's Drug Intervention Programme (DIP) through treatment and rehabilitation at Puspen centres, by reducing drug dependency and preventing relapse, treatment must be consistent with the principles of human rights for it to be effective. Data and information were gathered from empirical research through the application of various qualitative methods: these include a case study, direct observation, semistructured and unstructured interviews with key stakeholders, focus group with former drug users and an analysis of case files. Findings revealed that the legal process of funneling 'suspected drug dependants' into treatment involved a series of breaches of the fundamental human rights principles that could not be justified. The scope of police powers with regard to the arrest and detention of 'suspected drug dependants' has been widely abused and such exercise of power has been without proper statutory safeguards to protect the rights of these individuals from such arbitrary arrest. Unnecessary prolonged period of detention have led to grave infringement of individual liberty whilst conditions of confinement and failure to provide medical assistance and medication-assisted treatment particularly during withdrawal symptoms have amounted to inhuman, cruel and degrading treatment. Lack of due process including denying the right to legal representation has caused severe legal implications upon the drug users. As a consequence, the flaw in the legal system has deprived them of their constitutional rights and in contravention of the international human rights principles. Recommendations are proposed for an immediate reform to the drug policies and procedures with paramount consideration towards a more humane and effective treatment
