Many cultural and social psychological studies have been conducted at the societal level and at the individual level and generalised for all members in that society. This ignores the fact that there are many distinctive subgroups with their own subgroup cultures within a society. These subgroup cultures also have an influence on individuals, and need to be explored at an individual level. A survey in both English and Chinese was posted to 1,869 Chinese private equity professionals in the People’s Republic of China and Hong Kong and resulted in 376 responses. The survey measured the core values and beliefs of individualism, collectivism, power distance, social axioms, Machiavellianism, Confucianism, and preferred negotiation style for those who have had overseas exposure in Anglo-Saxon countries and those who have not. The theories employed in the study were institutional theory, the resource-based view, and social psychological theories. A partial least squares structural equation model was used to determine relationships. Significant differences between Chinese private equity professionals who have worked or studied in Anglo-Saxon countries and those who had not were found for individualism, vertical collectivism, Machiavellian control and status, three aspects of Confucianism, and also the controlling negotiation style. The model devised can be adapted for other societal subgroups to measure, not just preferred negotiation styles, but other important organizational relationship-dependent factors such as leadership style, decision-making, and trust. The model can be employed to further understand many types of organisations and industries anywhere in the world.

This study investigates the role of transformational leadership in influencing students’ outcomes in public secondary schools using Kuwait as a case study. The standard of academic achievement in Kuwait’s public schools has been declining over the years, which calls for a different type of leadership to transform these schools. It is argued in this thesis that there is merit in bringing in private sector business models to the public education sector in order to transform the sector and improve the schools’ outcomes. Furthermore, not much research has been undertaken on the paths through which transformational leadership influences public school outcomes in developing countries such as Kuwait. Following a critical review of leadership literature, a theoretical model for leadership that is transformational was conceptualised and this formed the basis of hypotheses formation and data collection. The thesis is thus original in its attempt to understand the paths through which school heads’ transformational leadership influence student’s outcomes in public secondary schools in a developing country (Kuwait). The study adopted a positivist ontology and objective epistemology and obtained data from 495 school heads and staff from 86 public secondary schools in Kuwait via a structured questionnaire. Confirmatory factor analysis (CFA) and structural equation models (SEM) tested the direct and indirect effects of school heads’ transformational leadership in influencing students’ outcomes the student “achievement” and the student “engagement” via several mediating variables including “school culture”, “class room condition” and “academic emphasis”. The analysis identified idealized influence (attributes) and idealized influence (behaviour) as the underlying dimensions of transformational leadership that directly and indirectly influences both student engagement and student achievement as the final outcome. The findings also confirmed differences between males and females in their leadership styles and subsequent influence on students’ achievement, and student engagement with the latter appearing to be better school heads. Therefore, two structure equation models were built to investigate the characteristics of each gender leadership style on the outcome variables. The findings also revealed that males’ leadership style has significant effect on student achievement but not student on engagement, while female leader ship style has significant effect on both student achievement and student engagement stronger than the males’ effect counterpart. Generally however, transformational leadership style has significant effect on both student achievement and student engagement. The study objectives were met and the study contributes to understanding the role of transformational leadership and its influence on staff and students’ achievement, from a developing country in the GCC. Managerial recommendations and suggestions for policy makers are made. Study limitations are highlighted leading to suggestions for further study.

Background: Understanding complex psychological treatment mechanisms is important in order to refine and improve treatment. Mechanistic theories can be evaluated using mediation analysis methods. The Pacing, Graded Activity, and Cognitive Behaviour Therapy: A Randomised Evaluation (PACE) trial studied complex therapies for the treatment of chronic fatigue syndrome. The aim of the project was to study different mediation analysis methods using PACE trial data, and to make trial design recommendations based upon the findings. Methods: PACE trial data were described using summary statistics and correlation analyses. Mediation estimates were derived using: the product of coefficients approach, instrumental variable (IV) methods with randomisation by baseline variables interactions as IVs, and dual process longitudinal structural equation models (SEM). Monte Carlo simulation studies were done to further explore the behaviour of IV estimators and to examine aspects of the SEM. Results: Cognitive and behavioural measures were mediators of the cognitive behavioural and graded exercise therapies in PACE. Results were robust when accounting for correlated measurement error and different SEM structures. Randomisation by baseline IVs were weak, giving imprecise and sometimes extreme estimates, leaving their utility unclear. A flexible version of a latent change SEM with contemporaneous mediation effects and contemporaneous correlated measurement errors was the most appropriate longitudinal model. Conclusions: IV methods using interaction IVs are unlikely to be useful; designs with randomised IV might be more suitable. Longitudinal SEM for mediation in clinical trials seems a promising approach. Mediation estimates from SEM were generally robust when allowing for correlated measurement error and for different model classes. Mediation analysis in trials should be longitudinal and should consider the number and timing of measures at the design stage. Using appropriate methods for studying mediation in trials will help clarify treatment mechanisms of action and allow for their refinement, which would maximize the information gained from trials and benefit patients.

Little is known about the spatial distribution and abundance of tree holes in New Zealand’s native forests, or the invertebrate communities that they support. I found that tree holes were common on five endemic tree species, belonging to the families Fagaceae and Podocarpaceae in the mixed broadleaf-podocarp rainforest of Orikaka Ecological Area, Buller District, New Zealand. However, tree holes were not uniformly distributed throughout the forest, with more holes found on the three podocarp species, Prumnopitys ferruginea, P. taxifolia and Dacrycarpus dacrydioides, than on Nothofagus fusca or N. menziesii. Nevertheless, Nothofagus fusca had the largest holes of any of the tree species sampled and larger trees generally had larger holes. Large, hole-bearing Nothofagus fusca trees support a specialist hole-dwelling vertebrate fauna in New Zealand and worldwide, tree holes provide habitat for a range of invertebrate species. Using specially-designed emergence traps, I collected invertebrates emerging from naturally-occurring dry tree holes and compared this assemblage with invertebrates inhabiting leaf litter on the forest floor and those dispersing aerially throughout the study area. At the higher taxonomic resolution (i.e., Order or Class), community composition within the tree holes was highly variable, and there was no strong distinction between invertebrates from tree holes, leaf litter or Malaise traps. Moreover, although some beetle species emerging from tree holes were found exclusively in tree holes, most of these were represented by a single individual. Consequently, only minor differences in species composition were detected between beetle assemblages from tree holes, leaf-litter and those aerially dispersing throughout the forest. In contrast, the aquatic invertebrate assemblage within water-filled tree holes was highly distinctive from that in ground-based freshwater ecosystems, with only six aquatic taxa in common between all freshwater habitats. Using experimental water-filled tree-hole microcosms, I found that species richness and community composition within these microcosms were primarily driven by resource concentration, although habitat quality (i.e., water chemistry parameters) was also an important determinant of the identity and composition of colonising species. Overall, my study has shown that tree holes are common in the study area, and are likely to be more abundant in New Zealand’s indigenous forests than previously thought. Moreover, these generally small, discrete forest ecosystems support a diverse array of terrestrial invertebrates as well as a distinctive aquatic invertebrate community that is primarily structured by organic matter resource availability. These findings not only represent an important advance in our knowledge of New Zealand’s freshwater invertebrate biodiversity, but also highlight the need for further investigation into these unique forest canopy habitats which may well be at risk from deforestation and land use change.

Technology acceptance research is a constantly developing field. The disciplines that contributed to its development are either beliefs focused or system focused. The unified theory of acceptance and use of technology (UTAUT) combined both. The current research model proposes an extension to the UTAUT that accounts for online usage behaviour. The proposed research model is tested in two countries (UK and Jordan) to investigate the viability of the unified model of technology acceptance in different boundaries as a model of individuals’ discretionary usage of Internet banking. The study also questions the roles of other determinants and moderators in this context. Results found support for the effect of the proposed extension, website quality perceptions, on usage behaviour in both countries’ models; the total effect of this extension exhibited website quality perceptions the most influential determinant of usage behaviour in both models and performance expectancy construct was second in effect. Social influence had no impact on the usage behaviour in both models, which is consistent with previous research that advocates a declining role of social influence under discretionary usage and increased experience conditions. Furthermore, the moderating role of performance expectancy previously established in TAM’s research was supported in the UTAUT model in both countries’ models. Moreover, both models reported a non-moderating effect of gender, which, is also in line with recent research findings that suggest declining gender differences under voluntary usage conditions and advanced experience. Education and income were moderators only for the UK model. Although the research findings demonstrated that both countries’ models were “configurally” similar with respect to model specifications, the models’ explanatory power for usage behaviour was dissimilar: the UK’s model explanatory power exceeded that of Jordan’s model presenting an opportunity for future research. The current research contributes to knowledge in the field of technology acceptance research. It demonstrated that website quality perceptions, as a multidimensional concept, play an important role in the online usage context. It also demonstrated that the unified model of technology acceptance established in the western culture can be transferred to a non-western culture although with varying degrees of explanation power.

Aims: To study practices and procedures with respect to electrotherapy in physiotherapy departments and to study physiotherapists’ perception of health risk, health consequences and protection of health from different risks including electromagnetic field emissions from electrotherapy devices. Methods: This cross-sectional study was conducted in three phases from June 2002 to December 2003. The first phase was an audit of the practices and procedures regarding electrotherapy in National Health Service physiotherapy departments (N = 46 including 7 departments in pilot study) located in 12 counties in the southeast and southwest of England including Greater London. The second phase comprised one observational visit to each of the same physiotherapy departments to characterise their occupational environment. The third phase was a questionnaire survey of 584 physiotherapists working in these departments. Variables concerned perception of health risk, health consequences and protection of health associated with different risk factors. Results: In the first two phases, the recruitment rate of the departments was 80.7% (46 out of 57) and response rate of those recruited was 100% (n=46). The response rate for the last phase of the study was 66.8% (390 out of 584). Results of the practices and procedures audit show that ultrasound was the most common form of electrotherapy while microwave diathermy was neither available nor used in these departments. Pulsed shortwave diathermy was used 4-5 days per week while continuous shortwave diathermy was used rarely. Electrotherapy was provided to up to 50% of patients per week in the departments. The observational visits to the departments revealed that there were metallic objects within close proximity of diathermy equipment and wooden treatment couches for treatment with PSWD and CSWD were rare. The risk perception survey showed that physiotherapists generally perceived a moderate health risk and health consequences (harm) from exposure to EMF emissions from electrotherapy devices. Protection from EMFs in physiotherapy departments was generally perceived as ‘usually’ possible. Conclusions: Physiotherapy departments report safe electrotherapy practices. Use of diathermy devices that use RF EMFs is declining. The key predictors of physiotherapists’ perception of health risk were perception of health consequences and vice versa. Gender was a significant predictor of the perception of health risks and health consequences. The main predictor of perception of protection against risk was the knowledge of environmental and health issues. Latent dimensions of perceptions of health risk, health consequences and protection from risk were identified and confirmed and their predictors were determined.

SMEs are often described as slow adopters of technology. However, adopting e-commerce is one of many strategies taken by travel agents to re-intermediate themselves in the global travel market against the threat of disintermediation. Exploratory studies have revealed that Egyptian travel agents are laggards when it comes to technology adoption, although they perceive e-commerce as a beneficial tool that can increase their chances of survival. As many as 59.2% of Egyptian travel agents were found not to have websites (Egyptian Travel Agents Association, 2008), this study investigates the factors affecting e-commerce adoption by travel agents. Past literature has shown that there are three main factors affecting the adoption of e-commerce by SMEs. Environmental pressures push SMEs to adopt in order to bolster their survival chances. The benefits of adoption are critical factors considered by managers when making the adoption decision. Finally, there are barriers to e-commerce adoption. By modifying the technology acceptance model, this research conceptualizes the causal relationships amongst these three types of factors. The benefits and barriers to e-commerce adoption are found to mediate the relationship between environmental pressures and e-commerce adoption. This study employs mixed methods starting with a quantitative survey and following it up with qualitative interviews. A questionnaire was used to collect data from 411 adopter and non-adopter e-commerce travel agents. Later, 22 interviews were conducted with the managers of travel agents. Structural equation modelling produced findings reveal that environmental pressures significantly affect the perceived benefits of and barriers to adoption, in addition to having an indirect effect on adoption behaviour. This study contributes to theory as it responds to the claim that the factors affecting e-commerce adoption have not been well documented in the travel sector (Hung et al., 2011, Thomas et al., 2011), especially in the context of developing countries (Thulani et al., 2010). The findings reveal that the modified technology acceptance model successfully interprets e-commerce adoption. The study compares other adoption models with the research model and provides statistical criteria for this comparison. Its contribution to practice is twofold, affecting the managers of travel agencies and policy makers. Recognizing the factors affecting adoption would enable managers to devise strategies and prepare better agendas for expanding their businesses, while at the same time identifying any defects and training needs that present barriers. Meanwhile, recognizing the barriers to adoption could encourage government bodies and policy makers to implement appropriate measures, such as introducing protective and financial legislation to encourage SMEs to adopt technology, or to formulate national policies and initiatives aimed specifically at supporting the adoption of e-commerce by SMEs.

Although Operational Research (OR) has successfully provided many methodologies to address complex decision problems, in particular based on the rationality principle, there has been too little discussion regarding their limited consideration in IT evaluation practice and associated decision making satisfaction levels in an organisational context. The aim of this paper is to address these issues through providing a current account of diffusion and infusion of OR methodologies in IT decision making practice, and by analysing factors affecting decision making satisfaction from a Technological, Organisational, and Environmental (TOE) framework in the context of IT induced business transformations. We developed a structural equation model and conducted an empirical survey, which supported four out of five developed research hypotheses. Our results show that while Decision Support Systems (DSS), holistic IT evaluation methods, and management support seem to positively affect individual satisfaction, legislative regulation has an adverse effect. Results also revealed a persistent methodology diffusion and infusion gap. The paper discusses implications in each of these aspects and presents opportunities for future work. (authors' abstract)

Vicarious traumatisation (VT) has been defined as an experience of change in several domains of personhood including worldview, identity, and beliefs related to major psychological needs. Self-care practice is widely considered essential in sustaining personal and professional well-being, and a lack of appropriate practice can enhance the risk of VT in trainee and newly qualified therapeutic practitioners. Both quantitative and qualitative research suggests that mindfulness practice can have a protective role in the risk of VT for trainees. This study examined the relationship between VT, self-care and mindfulness in a sample of 238 trainee therapists from the UK, Australia, Canada and Ireland. Structural equation modelling was used to test a mediation model with good fit with self-care as predictor variable, mindfulness as mediator, and VT as outcome variable. The hypothesis that when controlling for the effects of mindfulness on VT the effect of self-care on VT is no longer significant could not be confirmed as no mediational effect was present. The hypothesis that predicted a negative association between self-care practice and VT was confirmed with a significant total effect although the direct effect of self-care on VT was not significant. Findings are discussed in relation to previous research involving mindfulness in trainee cohorts. Links are made with neuroscience research to consider underlying mechanisms of mindfulness within the context of VT.

The performance of own-label brands varies enormously across countries, with high penetration in Western countries but limited success in Eastern countries. The common explanations for this state are related to market factors such as the development of big retailer chains or the power balance between retailers and manufacturers. However, the role of culture has been overlooked to explain this situation. This study aims to provide insights into the impact of culture on own-label brands performance. This thesis formulates and tests a conceptual framework linking Hofstede s (1980, 2001) five cultural dimensions (power distance, individualism, masculinity, uncertainty avoidance & long-term orientation) to retail market development (size of the retail market) and own-label brands performance, controlling for three socio-economic variables: GDP per capita, Gini index and Government expenditure. Relevant literature is reviewed in order to develop hypotheses. The conceptual model is then tested upon a sample of 65 countries, utilising data collected via secondary sources and the application of structural equation modelling techniques. The results of this study indicate that three out of five Hofstede s cultural dimensions, power distance, individualism and uncertainty avoidance, have a significant impact on retail market development, which in turn, significantly influences own-label brands performance. Moreover, results show that individualism and long-term orientation have a significant direct impact on own-label brands performance. Past studies on this domain are restricted to one or two cultural dimensions and generally involve a limited number of countries. This research therefore pioneers in investigating the five national cultural dimensions across a high number of nations. The findings are important for retailers and may help them to adapt their own-label strategy according to the culture of the nation they are operating in.
