Prior work in the transformational leadership realm has focused primarily on relations among leader behaviors and various criteria such as subordinate satisfaction and effectiveness. This restrictive focus has limited the degree to which one of Bass's (1985a) central arguments can be directly assessed; namely, that optimally effective leaders engage in both transformational and transactional behaviors. In this study, an analytic technique known as the pattern approach was employed to effectively discern which particular pattern of leader behaviors was associated with the highest levels of subordinate satisfaction and commitment. In general, the most effective leaders used a combination of transformational (e.g., stimulating subordinates to think of old problems in new ways; presenting a charismatic and inspirational view of the future) and contingent reward (e.g., providing pay or promotions in exchange for effective subordinate performance) behaviors, coupled with a low level of passive management-by-exception behaviors (e.g., remaining uninvolved until problems emerge). These optimally effective leaders were generally more successful than leaders who used predominantly one (e.g., transformational or transactional) behavioral style. / Ph. D.

Maladaptive habits, such as substance use, that are highly ingrained and automatized behaviors with negative long-term health consequences need effective interventions to promote change towards more healthful behaviors. Implementation intentions, the structured linking of critical situations and alternative, healthier responses, have been shown to improve health-benefiting behaviors such as eating more fruits and vegetables and being more physically active (Sheeran, Milne, Webb, and Gollwitzer, 2005). Here, a laboratory analogue for smoking relapse and a pilot clinical trial of alcohol use are assessed using implementation intention interventions to reduce these health risk behaviors. In Study 1, heavy smokers completed a smoking resistance task that is a candidate analogue for smoking relapse. Participants were exposed to an in-laboratory implementation intention and/or monetary incentive condition during each of four experimental sessions. The combined implementation intention and monetary incentive condition resulted in the greatest delay to smoking initiation. In Study 2, individuals with alcohol use disorder completed an active or control implementation intention treatment condition. Remotely, both treatment groups received a daily ecological momentary intervention, thrice daily biologic breath alcohol ecological momentary assessments, and once daily self-report ecological momentary assessment of alcohol consumption during the intervention period. The active implementation intention group was associated with a greater reduction in alcohol consumption compared to the control group. Together, these studies provide experimental and initial clinical evidence for implementation intentions, in conjunction with other effective treatments (Study 1) and technological advancements (Study 2), to intervene on and reduce substance use. This project is the first to use implementation intentions in a laboratory evaluation of smoking resistance and in an initial clinical trial to reduce alcohol consumption in a naturalistic community sample using both ecological momentary assessments and ecological momentary interventions. / Ph.

Yes / Increased use of smart technologies by customers is leading to recognition of their influence on the shopping experiences of customers by practitioners. However, the academic literature fails to acknowledge the influence of smart technology usage, combined with behavioural intention of the customer, on the dynamics and experience of customers. This research utilises explanatory research at the preliminary stage to examine this phenomenon in a retail setting. A conceptual framework was created, based on the scholarly knowledge available in extant literature, and was tested using a survey of a convenience sample of 330 consumers shopping in a high-end retail store in London, United Kingdom. Structural Equation Modelling (SEM) via AMOS was employed to test the proposed model. This study contributes to technology adoption based consumer behaviour literature, by explaining the ability of learning commitment to drive the participation of an individual, but its inability to influence their behavioural intention. Findings of this research also reflect on the role of customer dynamics and customer experience in embracing innovative application of smart technologies in a retail setting. The results and implications included in our study also contribute to the understanding of the determinants that affect customer dynamics and customer experience when making use of smart technologies.

Yes / Whilst previous studies indicate perceived company ethicality as a driver of job seekers’ job-pursuit intentions, it is poorly understood how and why ethical market signals actually affect their application decisions. Perceptions of company ethicality result from market signals that are either within the control of the company (e.g. ethical certifications) and from market signals that are beyond the company’s control (e.g. ethical eWoM). Building on communication and information processing theories, this study therefore considers both types of ethical market signals, and examines the psychological mechanisms through which they affect job seekers’ intention to apply for a job. The results from a controlled online experiment show that both types of ethical market signals increase job seekers’ job-pursuit intentions. These relationships are mediated by applicants’ attitude towards the job advertisement, their perceptions of corporate employment image and self-referencing. Consequently, the present study alerts practitioners to consider the effects of company-controlled and non-company-controlled ethical market signals, particularly when aiming to recruit highly-qualified millennial candidates.

Yes / This research examines the extent to which immigrant consumers' use of social networking sites affect their socialization and political engagement in the Netherlands. The study uses self-administered questionnaires to collect data from 514 Turkish-Dutch respondents of various ages, occupations, levels of education and locations in the Netherlands. The study finds that the propensity to share information, the intensity of use, and privacy concerns positively impact socialization on online social networking sites. In addition, a significant positive relationship between socialization and political involvement positively impacts voting intentions. The study also examines the interaction effects of enculturation and acculturation orientations on the relationship between socialization and political involvement. The study's findings point to a positive moderating role of acculturation in this relationship but a negative one for enculturation. The study is the first to investigate simultaneously the drivers of socialization on social networking sites in the context of immigrant consumers and the impact of their socialization on political involvement and voting intention. The research further contributes to the scholarly work by exploring the interaction effects of acculturation and enculturation orientation. Theoretical and practical implications are discussed.

Yes / This study examines the extent to which acculturation and enculturation orientations affect online political participation, political involvement and voting intentions among a sample of Turkish-Dutch immigrants. The study uses data from Turkish-Dutch participants. Structural Equations Modelling (SEM) is employed for assessing the relationships in the conceptualized model. The findings show that enculturation and acculturation influence online participation and involvement, which in turn, are related to voting intentions. The study further examines the mediating role of political involvement and online political participation. Political involvement mediates the relationships between enculturation and acculturation and voting intentions. The results further indicate the effect of online participation on voting intentions is mediated by political involvement. The study findings provide insights into offline and online cultural and civic engagement tendencies among an important immigrant segment that policy makers should consider in the future.

Yes / Social media has emerged as a significant and effective means of assisting and endorsing activities and communications among peers, consumers and organizations that outdo the restrictions of time and space. While the previous studies acknowledge the role of agents of culture change, it largely remains silent on the role of social media in influencing acculturation outcomes and consumption choices. This study uses self-administered questionnaire to collect data from 514 Turkish-Dutch respondents and examines how their use of social media affects their acculturation and consumption choices. This research makes a significant contribution to consumer acculturation research by showing that social media is a vital means of culture change and a driver of acculturation strategies and consumption choices. This study is the first to investigate the role of social media as an agent of culture change in terms of how it impacts acculturation and consumption. The paper discusses implications for theory development and for practice.

Yes / Regional monopoly service organisations such as electricity, gas and water distributors, health trusts, public transport, and local government are subject to regulatory oversight. A common element in this is benchmarking an organisation against similar organisations based in different regions. Customer satisfaction is often an important part of this competitive benchmarking. However, if people from different regions give a different average satisfaction score for the same experience, then this disadvantages some companies. Therefore, regional satisfaction was investigated in an environment where differences in customer service levels are controlled for. The average online satisfaction ratings people from different regions of the UK gave to the same overseas holiday hotels were investigated. The 24,154 ratings were analysed using linear mixed effects and ordinal models. The average ratings given by people from the London region were significantly lower than those from elsewhere. Regional correction factors are developed and applied to published satisfaction ratings for electricity distributors. The adjustment was sufficient to move the London distributor from the penalty category to a borderline position. Hence, customer satisfaction ratings should be used cautiously when benchmarking regional organisations. This investigation of the potential for regional bias contributes to the large literature on customer satisfaction and behavioural intentions.
