Background: Coronary heart disease (CHD) remains a major cause of death and ill- health in Scotland. Coronary artery bypass grafting (CABG) aims to relieve CHD symptoms, improve quality of life and increase life expectancy in high-risk groups. Partners may positively or negatively influence patient outcome, and they too may be adversely affected by the experience of CABG. Health care is currently organised around the patient. The partner's is seen as merely assisting patient recovery. Their health and well-being is neglected despite them being at an increased risk of CHD. Research has been limited in the partner variables that have been examined. Their health needs and concerns and the influence of the patient on partner outcome have seldom been examined and the effects of CABG on the dyad. The dyad has not previously been examined as an outcome variable of interest.

The purpose of this programme of research was to investigate the existence and development of shared understanding between football dyads through quantitative and qualitative research methods. Research has considered the importance of shared understanding between team members (Williamson and Cox 2014, Gershgoren et al. 2016) but rarely dyads within teams (i.e. Blickensderfer et al. 2010). Study One attempted to establish the existence of shared understanding between twenty football dyads. Study Two explored the levels of shared understanding displayed by forty-five defensive football dyads in game situations that had either a clear correct course of action or when there was no clear correct course of action. Through an interview-based approach, Study Three investigated potential factors that could contribute to the development of shared understanding between football dyads, based on the suggestions of twelve football players. Through these different methods, the three studies have provided evidence to support the existence and development of shared understanding between football dyads. The main findings of the thesis (a) shared understanding exists between dyads who have experience performing together, (b) when dyads are in a situation where there is a clear and correct option available, they are more likely to choose the same option based on their own individual experience, (c) when dyads are in a situation where there is no clear and correct option available, they are more likely to pick the same option based on their experience performing together, (d) experience performing together, having an efficient relationship with their partner, effective communication methods between one another and the role of the coach facilitated the development of shared understanding between dyads and (e) these factors facilitate an effective shared mental model between dyads.

abstract: Human-robot interaction has expanded immensely within dynamic environments. The goals of human-robot interaction are to increase productivity, efficiency and safety. In order for the integration of human-robot interaction to be seamless and effective humans must be willing to trust the capabilities of assistive robots. A major priority for human-robot interaction should be to understand how human dyads have been historically effective within a joint-task setting. This will ensure that all goals can be met in human robot settings. The aim of the present study was to examine human dyads and the effects of an unexpected interruption. Humans’ interpersonal and individual levels of trust were studied in order to draw appropriate conclusions. Seventeen undergraduate and graduate level dyads were collected from Arizona State University. Participants were broken up into either a surprise condition or a baseline condition. Participants individually took two surveys in order to have an accurate understanding of levels of dispositional and individual levels of trust. The findings showed that participant levels of interpersonal trust were average. Surprisingly, participants who participated in the surprise condition afterwards, showed moderate to high levels of dyad trust. This effect showed that participants became more reliant on their partners when interrupted by a surprising event. Future studies will take this knowledge and apply it to human-robot interaction, in order to mimic the seamless team-interaction shown in historically effective dyads, specifically human team interaction. / Dissertation/Thesis / Masters Thesis Engineering 2019

A potential solution to producing quality software in an acceptable time frame may be found by using the newer, innovative methods, such as collaborative software development. The purpose of this dissertation is to examine the individual developer characteristics, developmental settings, collaborative methods and the processes during development that impact collaborative programming performance and satisfaction outcomes. Understanding individual differences in performance in the collaborative development setting is important, since it may help us understand how the collaborative setting may raise the lowest level of performance to much higher levels, as well as how to select individuals for collaborative development. Exploring the impact of the virtual setting on collaborative development processes is important as it may help us improve performance outcomes in different work settings. Investigating how adaptations of pair programming impact collaborative processes may assist in implementing changes to the method that enhance quality and individual satisfaction. A multi-phase methodology is used, consisting of an intensive process study (Study 1) and two laboratory experiments (Studies 2 and 3). Study 1 illustrates that collaborative programming (pair programming) outcomes are moderated by both individual developer differences and the processes used during development. While cognitive ability and years of IT experience are important factors in performance, the impacts of conflict and the faithful appropriation of the method are highlighted. Distributed cognition is used as a theoretical foundation for explaining higher performance. Study 2 findings suggest that while collaborative programming is possible in a virtual setting, performance is negatively impacted. Face-to-face programmers have significantly higher levels of task performance, as well as satisfaction with the method, when compared to virtual programmers. Study 3 results suggests that the use of structured problem solving (preparing test cases before writing code) may be a key factor in producing higher quality code, while collaboration may be indusive to higher levels of developer satisfaction.By understanding how, why and when collaborative programming techniques produce better performance outcomes and what factors contribute to that success, we add to the body of knowledge on methodologies in the MIS domain.

First studies of electron transfer in [N]phenylenes were performed in bimolecular quenching reactions of angular [3]- and triangular [4]phenylene with various electron acceptors. The relation between the quenching rate constants kq and the free energy change of the electron transfer (ΔG0CS ) could be described by the Rehm-Weller equation. From the experimental results, a reorganization energy λ of 0.7 eV was derived. Intramolecular electron transfer reactions were studied in an [N]phenylene bichomophore and a corresponding reference compound. Fluorescence lifetime and quantum yield of the bichromophor display a characteristic dependence on the solvent polarity, whereas the corresponding values of the reference compound remain constant. From the results, a nearly isoenergonic ΔG0CS can be determined. As the triplet quantum yield is nearly independent of the polarity, charge recombination leads to the population of the triplet state.

The American Cancer Society estimates nearly 1.5 million Americans will be diagnosed with cancer this year. Existing on cancer and its effects on family communication indicate there are few things that have the potential to shake a family to its core like a serious illness (Anderson & Geist Martin, 2003; Gotcher, 1993; Northouse, 2005; Sherman & Simonton, 2001). Communication is one of the most important elements in determining and influencing families' emotions, patients' quality of life, patient care, family relationships and caregiver stress (Beach, 2001). The mother-daughter dyad represents one of the most significant relationships to analyze with respect to the impact cancer has within the family since mothers are typically the primary role models for their daughters (Miller, 1995). Using interviews with mother/daughter dyads, this study seeks to examine changes in communication between mothers and daughters following the mother's cancer diagnosis. The mother-daughter dyad is of most interest in this study for several reasons, most notably that this relationship is the “first dyadic relationship a female child has” (Bishop, 1992, p. 58); additionally, mothers are typically the primary role models for their daughters (Miller, 1995). This study aims to shed light on the relational changes that occur following a cancer diagnosis.

<p>Although it has been hypothesized that chronic emotional invalidation by a parent may have lasting effects on later ability to regulate emotions, and possibly increase the chances of experiencing symptoms of psychopathology, the possible mechanisms surrounding this relationship have not been adequately explored. Further, many investigations have used retrospective reports of invalidation, which may be subject to bias. This pilot study of 19 adolescent-parent dyads explored associations between invalidation, experiential avoidance, and child symptoms of psychopathology in a cross sectional design. Retrospective reports of invalidation as well as an observationally-coded measure of invalidation during laboratory discussions of emotion were utilized, and compared for agreement. The feasibility and acceptability of a larger investigation of these questions is also discussed. It was found that adolescent-reported recalled invalidation seemed to show a stronger pattern of association with observationally coded invalidation than do parent reports. Additionally, several alternative mechanistic hypotheses showed some promise for further exploration. This pilot study was found to be acceptable to participants; however, recruitment of adolescents from a clinical population - and their parents to participate with them - was the greatest obstacle to feasibility for a larger study.</p> / Dissertation

Collective case study (Creswell, 2014; Stake, 1995) was used to explore the journey of coach-athlete dyads who were able to successfully maintain their training and interpersonal relationships throughout the course of the athlete enduring a mental block. Three coach-athlete dyads, plus one additional athlete, completed in-depth one-on-one interviews, discussing their coach-athlete relationship before, during, and after the mental block. All dyads were same sex, nationally ranked coach-athlete pairs, from sports involving mandatory elements that include both twisting and flipping components. Categorical aggregation of participant statements lead to the formation of five main themes associated with dyads successfully overcoming a mental block (where success was defined as the athlete regaining the ability to perform the skill that they had previously been unable to do on account of the mental block and the dyad maintaining their training and interpersonal relationship): 1) Get to Know Your Athlete: The Need for High Quality Communication; 2) Be a United Front; 3) Mistakes and Miscommunications Happen: Recovery is Key; 4) Seek Outside Resources; 5) Be Patient. Results suggest that an environment for success can flourish when each party is open, honest, and self-aware of their own limitations. It is suggested that future research utilize the 3 + 1Cs Model of the coach-athlete relationship in exploring how dyads can successfully overcome a mental block.

The overall efficiency of photovoltaics is dictated by processes occurring within it. These processes include exciton formation, diffusion, dissociation and charge collection. This dissertation will focus around the fundamental issue of charge collection. In organic photovoltaics (OPVs) the rate of charge injection is dominated by the interaction between dissimilar materials, usually organic compound interacting with inorganic ones. In order to improve this rate of injection and, by direct consequence the efficiency of this process, fundamental knowledge of this organic-inorganic interface must be gained. In this work the focus will reside solely on creating molecules capable of probing the interface between the indium tin oxide (ITO) and the donor layer. At this interface, the usual charge transfer being transferred is the hole. Chapters 2 and 3 detail the synthesis and photophysical characterization of porphyrin-perylene diimide (Por-PDI) and porphyrin-fullerene (Por-C₆₀) molecular dyads. The idea behind these moieties is that covalent attachment of these species to ITO should lead to a robust ohmic contact. Since these molecular dyads are capable of producing charge-separated states after photoexcitation, they should have the capacity to produce a radical-cation in close proximity to the ITO. This will translate to a capacity for probing the dynamics of the hole injection at this interface. Studies performed demonstrate that in fact these dyads are capable of producing a charge-separated state upon photo-excitation. The lifetimes of these states were determine to be 35 ps and 3 ns for the Por-PDI and Por-C₆₀ respectively. Chapter 4 takes a different turn. It is focused on the application and extension of a solvent-free synthesis of metallated phthalocyanines (Pcs). Shown in chapter 4 is the synthesis of a series of metallated Pcs using various transition metals and group 3 elements. Photophysical and electrochemical investigation of these materials shows that they have near-infrared absorption and relative high HOMO levels making them potential candidates for OPV applications. In addition, they displayed non-linear optical behavior due to their highly polarizable pi-systems and the presence of axial susbtituents. Finally Chapter 5 describes the synthesis and characterization of porphyrin possessing rigid linkers. This chapter also shows the further directions in which the various ideas presented in this work could be driven.
