description: A reliable methodology is essential for accurately estimating the parameters of PV models, enabling reliable performance evaluations, effective control studies, accurate analysis of partial shading effects, and optimal optimization of Photovoltaic (PV) systems. It ensures that the obtained parameters reflect the true characteristics of the PV system, leading to more accurate and reliable results in various applications. The existing literature extensively explores the utilization of powerful Metaheuristic Algorithms (MAs) to address the complex constrained optimization problem in PV systems and achieve optimal solutions. However, it is important to note that a significant portion of these MAs primarily concentrates on the development of methodologies, often overlooking the design of the objective function tailored for PV systems. This oversight has created a theoretical gap in this research domain, underscoring the necessity for additional exploration and investigation to address this limitation. To address the existing theoretical gap, this study focused on developing an objective function that accurately estimates the initial root parameters of Photovoltaic (PV) models. This objective function was designed by incorporating the first-order Berndt-Hall-Hall-Hausman (BHHH) numerical method, along with the non-linear damping parameter of the Levenberg-Marquardt technique (LM). By implementing this approach, the study aimed to significantly improve the precision and reliability of estimating the initial root parameters in PV models, effectively filling the theoretical void in this specific research area. Then in terms of methodology, the Enhanced Henry Gas Solubility Optimization (EHGSO) algorithm is combined with the Sine-Cosine mutualism phase of Symbiotic Organisms Search (SOS) for efficiently estimating the unknown parameters of PV models. The keystone of EHGSO in terms of methodology enhances exploration at the beginning of optimization and intensifies exploitation in later iterations. The proposed EHGSO methodology based on the adaptive damping BHHH technique (EHGSOAdBHHH) is tested on Single Diode (SD), and Double Diode (DD) PV models using actual experimental data. EHGSOAdBHHH exhibits outstanding accordance with attained experimental data compared with other algorithms, and its superiority is validated using several statistical criteria

description: The dominant contribution to the energy relaxation of state-of-the-art superconducting qubits is often attributed to their coupling to an ensemble of material defects which behave as two-level systems. These defects have varying microscopic characteristics which result in a large range of observable defect properties such as resonant frequencies, coherence times and coupling rates to qubits $g$. Here, we investigate strategies to mitigate losses to the family of defects that strongly couple to qubits ($g/2π\ge$ 0.5 MHz). Such strongly coupled defects are particularly detrimental to the coherence of qubits and to the fidelities of operations relying on frequency excursions, such as flux-activated two-qubit gates. To assess their impact, we perform swap spectroscopy on 92 frequency-tunable qubits and quantify the spectral density of these strongly coupled modes. We show that the frequency configuration of the defects is rearranged by warming up the sample to room temperature, whereas the total number of defects on a processor tends to remain constant. We then explore methods for fabricating qubits with a reduced number of strongly coupled defect modes by systematically measuring their spectral density for decreasing Josephson junction dimensions and for various surface cleaning methods. Our results provide insights into the properties of strongly coupled defect modes and show the benefits of minimizing Josephson junction dimensions to improve qubit properties.

description: Foetal Alcohol Spectrum Disorder (FASD) is a highly prevalent diagnosis worldwide however considering this there relatively very little research completed into this area, and considerable lack of research with the UK population. FASD can have a significant impact to a person across their lifespan, and a wider impact to those caring for and supporting an individual with difficulties associated to FASD. Unfortunately, there is a significant lack of understanding, awareness and support offered to people with FASD in worldwide. This thesis aims to raise awareness and understanding of the diagnosis in the UK by presenting two empirical research papers. Part one of this portfolio aims to provide an overview of the cognitive and executive functioning of children with a diagnosis of FASD in the UK by using secondary data from a national UK assessment service. The findings of this analysis show children with a diagnosis of FASD perform significantly below the normative average across the majority of cognitive and executive functioning assessments. The analysis identifies relative strengths for this group and outlines significant areas of weaknesses. The second part of this portfolio aims to change the deficit-based narrative of understanding FASD by using a strengths-based approach with adults with a diagnosis of FASD. Using semi-structured interviews to explore general strengths and specific executive functioning strengths within this population. Reflective thematic analysis is used and themes are identified which highlight strengths in personal qualities, specific areas of strengths and strategies to help maintain well-being and achieve their goals. The importance of the results from both papers are discussed with the hope that clinical practice and understanding can be supported in this area.Part three of this portfolio provides an overview of the clinical work completed to obtain this degree.

description: Graphene flake-based dispersions are attractive materials for various applications in microelectronics because of their ease of fabrication and the potential to deposit them on diverse substrates. The integration of these materials into conductive networks and microdevices requires thorough knowledge of their mechanical material properties, including adhesion. This paper presents quantitative adhesion measurements of graphene flake networks on silicon dioxide (SiO${_2}$) via button shear testing (BST). In this method, shear forces are applied to prefabricated micrometric buttons until they delaminate, providing information about the shear strength of the underlying graphene. We applied BST to graphene flake networks with different flake structures and defect densities. Flat flakes, a flat network structure, and a high flake defect density improve adhesion. We further demonstrate that graphene flake networks have stronger adhesion than chemical vapor deposited monolayer graphene grown on copper and transferred to SiO${_2}$. Hexamethyldisilazane (HMDS) increases the total adhesion force by improving flake network formation. Finally, we provide flake-type-specific delamination patterns by combining BST, optical microscopy, and Raman spectroscopy. We establish BST as a quantitative technique for measuring the adhesion of graphene dispersions and show the crucial role of interflake junctions in the overall adhesion of graphene flake networks.

description: We disclose the thermodynamical properties of the apparent horizon in a nonsingular universe. We take into account the zero-point length correction to the gravitational potential and derive the modified entropy expression that includes zero-point length correction terms. We apply the first law of thermodynamics on the apparent horizon as well as the emergent gravity scenario to derive the modified Friedmann equations. Further, we examine the time evolution of the total entropy, including the entropy of the apparent horizon and the matter field entropy inside the horizon and find out that the generalized second law of thermodynamics is satisfied. We also investigate the cosmological implications of the modified cosmology through zero-point length. We observe that the zero-point length correction does not change the general profile of the universe evolution, however, it shifts the time of the phase transition in a universe filled with matter and cosmological constant. We explore the age of the universe for our model and observe that the predicted age of the universe becomes larger compared to the standard cosmology. By calculating the explicit form of Ricci and Kretchmann invariants, we confirm that in our model, the initial singularity of the universe is removed. This is an expected result, because the main motivation for considering zero-point length correction in the gravitational potential is to remove singularity at the origin.

description: We examine the impact of long-range Dzyaloshinskii-Moriya (DM) interaction in the extended $XY$ model on the phase diagram as well as the static and dynamical properties of quantum and classical correlation functions. It is known that in the nearest-neighbor $XY$ model with DM interaction, the transition from the gapless chiral phase to a gapped one occurs when the strengths of the DM interaction and anisotropy coincide. We exhibit that the critical line gets modified with the range of interactions which decay according to power-law. Specifically, instead of being gapless in the presence of a strong DM interaction, a gapped region emerges which grows with the increase of the moderate fall-off rate (quasi-long range regime) in the presence of a transverse magnetic field. The gapless chiral phase can also be separated from a gapped one by the decay patterns of quantum mutual information and classical correlation with distant sites of the ground state which are independent of the fall-off rate in the gapless zone. We observe that the corresponding critical lines that depend on the fall-off rate can also be determined from the effective central charge involved in the scaling of entanglement entropy. We illustrate that in a non-equilibrium setting, the relaxation dynamics of classical correlation, the decay rate of total correlation, and the growth rate of entanglement entropy can be employed to uncover whether the evolving Hamiltonian and the Hamiltonian corresponding to the initial state are gapped or gapless.

description: This thesis investigates the ways in which select groups and their advocates interpret and seek to address the Indian Residential School (IRS) experience and legacy. It also considers the extent to which their aims are being realized through the Truth and Reconciliation Commission of Canada (TRC) and other components of the Indian Residential Schools Settlement Agreement (IRSSA). Through the qualitative content analysis of data gathered from four organizations, and in-depth interviews with six of their representatives, this study has uncovered that despite the somewhat diverse methods used by these organizations and advocates to address the legacy of IRS, perspectives were nonetheless based on the same fundamental notion: the need to incorporate and pursue decolonizing principles and aims. Moreover, it found that while some goals were being forwarded by the TRC and IRSSA, in several ways, the official process underway in Canada has failed to incorporate the needs and aims of these organizations.

description: In this study, we have investigated the radiative and semileptonic decay of doubly heavy baryons. Our focus is to determine the static and dynamic properties such as ground state masses, magnetic moment, transition magnetic moment, radiative decay and heavy-to-heavy semileptonic decay rates including their corresponding branching fractions. The ground state masses are calculated by solving the six-dimensional hyperradial Schrödinger equation. The magnetic moments and transition magnetic moments for $J^P=\frac{1}{2}^+$ and $J^P=\frac{3}{2}^+$ baryons are also calculated. In addition, radiative M1 decay widths are computed from the transition magnetic moment. We have employed the Isgur-Wise function(IWF) to analyse the semileptonic decay widths of the doubly heavy baryons. The obtained results are compared with other theoretical predictions.

description: Microarray technology, as applied to the fields of bioinformatics, biotechnology, and bioengineering, has made remarkable progress in both the treatment and prediction of many biological problems. However, this technology presents a critical challenge due to the size of the numerous genes present in the high-dimensional biological datasets associated with an experiment, which leads to a curse of dimensionality on biological data. Such high dimensionality of real biological data sets not only increases memory requirements and training costs, but also reduces the ability of learning algorithms to generalise. Consequently, multiple feature selection (FS) methods have been proposed by researchers to choose the most significant and precise subset of classified genes from gene expression datasets while maintaining high classification accuracy. In this research work, a novel binary method called iBABC-CGO based on the island model of the artificial bee colony algorithm, combined with the chaos game optimization algorithm and SVM classifier, is suggested for FS problems using gene expression data. Due to the binary nature of FS problems, two distinct transfer functions are employed for converting the continuous search space into a binary one, thus improving the efficiency of the exploration and exploitation phases. The suggested strategy is tested on a variety of biological datasets with different scales and compared to popular metaheuristic-based, filter-based, and hybrid FS methods. Experimental results supplemented with the statistical measures, box plots, Wilcoxon tests, Friedman tests, and radar plots demonstrate that compared to prior methods, the proposed iBABC-CGO exhibit competitive performance in terms of classification accuracy, selection of the most relevant subset of genes, data variability, and convergence rate. The suggested method is also proven to identify unique sets of informative, relevant genes successfully with the highest overall average accuracy in 15 tested biological datasets. Additionally, the biological interpretations of the selected genes by the proposed method are also provided in our research work.
The Role and Function of Lydia as a Rhetorical Construct in Acts: A Sociorhetorical and Theological Interpretation

description: This thesis investigates whether Lydia of Thyatira functions as a figure that has a particular rhetorical and theological function and force in Acts 16:9-40. There are a number of factors that would suggest that Lydia was of interest to the author of Acts. These include Lydia’s placement at both the opening and closing to the Philippi visit, and the fact that the sole case of explicit divine initiative in the rhetorical unit is directed at Lydia. These and other indicators would suggest that it is highly probable that the author intended Lydia to contribute to the overall rhetorical movement and unity of the passage. Yet, biblical commentary has not been able to suggest how Lydia might contribute to the rhetorical development of the text. Ultimately, too many questions regarding Lydia’s prominent profile in the text have remained unanswered. In response to uninvestigated questions raised by Lydia, this project employed socio-rhetorical interpretation (SRI), an exegetical approach that understands the cultural and social embeddedness of a rhetorical text. By means of an SRI analysis it was possible to identify the salient topoi of Acts 16:9-40, and to suggest how the author had used these in developing the rhetorical movement of the text. This project’s SRI analysis of Acts 16:9-40 shows that in stark contrast to the history of interpretation’s “Lydia the hostess,” a culturally-contextualized profile of Lydia presents the image of an immoral, degenerate, Lydian purple-selling “huckster.” Strikingly, however, Lydia’s inner heart is warranted by God, and her fidelity to God is argumentatively affirmed by the act of the Pauline group’s final visit to her home. In presenting Lydia through a cultural profile that would suggest a potential contaminant to a salvific “place of prayer,” the author sought to invert prejudicial cultural stereotype-centered socio-religious logic. Most significantly, the author sought to invert the type of cultural codes of material triumphalism that are embodied in the history of interpretation’s construct of high-status “Lydia the hostess” by portraying the disciples’ encounter with Lydia within a socio-cultural framework of shame and dishonour.

description: We explore the relationship between emotional well-being and economic freedom. Us-ing data for a sample of 12 countries from wave 2 of the World Value Survey (WVS) and the Economic Freedom of the World (EFW) index, we find that people living in more economi-cally free societies are more likely to report the presence of positive affect and absence of neg-ative affect. Specifically, people who live in countries with greater economic freedom are more likely to report feeling excited, accomplished, and on the top of the world. At the same time, they are less likely to report feeling pride, restlessness, loneliness, boredom, and being upset. These results are consistent with previous studies that find a positive association be-tween economic freedom and life satisfaction.

description: This thesis examines the contextual theology of John W. de Gruchy whose critique of the Dutch Reformed Church’s (DRC) iteration of a Reformed theology in support of apartheid, provided a theological cantus firmus for the church struggle against apartheid. There are two questions that guide this thesis. The first question I ask is, ‘Why, in 1986, did the Dutch Reformed Church recant its pro-apartheid stance which it had maintained, both officially and unofficially for one hundred and thirty-nine years?’ The second question concerns John W. de Gruchy in his capacity as a leading theologian in the Christian church and as a representative of the Reformed tradition in South Africa. I ask, ‘What was his role in the dismantling of the social experiment called apartheid?’ Drawing upon de Gruchy’s theological literature, written over the past fifty years, an argument is crafted suggesting that, by answering the second question, we also answer the first. To this end, a brief account of the Afrikaner rise to political and theological dominance in South Africa is provided with a view to establishing the social, political and economic context.

description: Building on our first paper in this series, we investigate the impact of radial magnetic fields and non-ideal magnetohydrodynamic (MHD) effects - specifically, Ohmic resistivity, Hall drift, and ambipolar diffusion - on RWI unstable modes. The presence of a radial field is linked to the disk's vertical shear and vertical magnetic field. We perform radially global linear analyses and utilize the spectral code \textsc{Dedalus} to solve the matrix eigenvalue problems. Our findings reveal that radial fields exhibit behavior similar to vertical fields. In the ideal MHD limit, radial fields enhance the effect of vertical fields in reducing growth rates, with significant reductions starting at relatively weak field strengths, around $β\sim 10^3 - 10^4$, which are relevant to protoplanetary disks. In the non-ideal MHD limit, all three non-ideal effects, when sufficiently strong, cause the growth rates to closely resemble those observed in hydrodynamic models.

description: Photocatalysis is an advanced oxidation process for the purification and remediation of contaminated waters and wastewaters, and is advantageous over conventional treatment technologies due to its ability to degrade emerging and recalcitrant pollutants. In addition, photocatalytic disinfection is less chemical-intensive than other methods such as chlorination, and can inactivate even highly resistant microorganisms with good efficacy. Process sustainability and cost-effectiveness may be improved by utilizing solar irradiation as the source of necessary photons for photocatalyst excitation. However, solar-induced activity of the traditionally-used titania is poor due to its inefficient visible light absorption, and recombination of photo-excited species is problematic. Additionally, mass transfer limitations and difficulties separating the catalyst from the post-treatment slurry hinder conversions and efficiencies obtainable in practice. In this research, various strategies were explored to address these issues using novel visible light active photocatalysts. Two classes of carbon-enhanced photocatalytic materials were studied: activated carbon adsorbent photocatalyst composites, and carbon-doped TiO2. Adsorbent photocatalyst composites based on activated carbon and plasmonic silver/silver chloride structures were synthesized, characterized, and experimentally investigated for their photocatalytic activity towards the degradation of model organic pollutants (methyl orange dye, phenol) and the inactivation of a model microorganism (Escherichia coli K-12) under visible light. The adsorptive behaviour of the composites towards methyl orange dye was also studied and described according to appropriate models. Photocatalytic bacterial inactivation induced by the prepared composites was investigated, and the inactivation mechanisms and roles of incorporated antimicrobial silver on disinfection were probed and discussed. These composites were extended towards magnetic removal strategies for post-use separation through the incorporation of magnetic nanoparticles to prepare Ag/AgCl-magnetic activated carbon composites, and the effect of nanoparticles addition on the properties and photoactivities of the resulting materials was explored. Another silver/silver halide adsorbent photocatalyst composite based on activated carbon and Ag/AgBr exhibiting visible light absorption due to both localized surface plasmon resonance and optical band gap absorption was synthesized and its photocatalytic activity towards organics degradation and microbial inactivation was studied. Carbon-doped mixed-phase titania was also prepared and experimentally investigated.

description: We attempt to apply the Regge trajectory approach to the triply heavy triquarks $((QQ')\bar{Q}^{\prime\prime})$ $(Q,\,Q',\,Q^{\prime\prime}=b,\,c)$. We present the triquark Regge trajectory relations, and then employ them to crudely estimate the spectra of the triquarks $((cc)\bar{c})$, $((cc)\bar{b})$, $((bc)\bar{c})$, $((bc)\bar{b})$, $((bb)\bar{c})$, and $((bb)\bar{b})$. The $λ$-trajectories and the $ρ$-trajectories are discussed. The triquark Regge trajectory becomes a new and very simple approach for estimating the spectra of triquarks. Moreover, the spin-averaged masses of the ground states of pentaquarks $(\bar{c}(cc))(cc)$, $(\bar{b}(cc))(cc)$ and $(\bar{c}(bb))(cc)$ are estimated, which are consistent with other theoretical predictions.

description: Animal shelter employees are in a unique position where they care for, and later kill, the same animals. The aim of our exploratory study was to assess whether “caring” and/or “killing” evokes physiological and psychometric indicators of stress in employees. Experiment 1 compared three careers that kill regularly, but involve varying degrees of husbandry (n = 28). Blood pressure (BP), salivary cortisol, heart rate (HR), and heart rate variability (HRV) were collected; data showed higher HR and lower HRV during the process of killing. Psychometric scales showed that burnout and Impact Event Scale-Revised (IES-R) scores were higher in careers with higher contact with animals. Experiment 2 compared three careers that involve husbandry, but varying exposure to killing (n = 41). BP, cortisol awakening response, HR, and HRV were measured as well as Professional Quality of Life Scale, IES-R, and Moral Injury Event Scale were administered. There were no significant differences across careers in any measures. The data suggest that the process of killing may be physiologically stressful to the person, and higher levels of animal contact in a euthanasia context may be associated with burnout and traumatic stress, but that the act of euthanasia is not a unique predictor of overall occupational distress.

description: Clara Wieck Schumann’s 1836 Piano Concerto Op. 7 represents an era of radical formal experimentation in the early nineteenth century. As such, critics including Robert Schumann questioned its unity, thus prompting late twentieth-century scholars to reassess both its departures from tradition and its cohesive mechanisms. I propose that the concerto’s formal innovations are a result of Wieck’s decision to construct a tripartite work from her autonomous Concertsatz, which became the Finale after the addition of a first and second movement. This study uses William Caplin’s theory of formal functions and Steven Vande Moortele’s theory of two-dimensional sonata form to examine how Wieck complemented the independent Finale with a formally divergent first movement, which facilitates the projection of an overarching sonata form spanning the entire work. In doing so, this study produces a model to assess the concerto’s internal logic.

description: Since the pandemic started, organisations have been actively seeking ways to improve their organisational agility and resilience (regility) and turn to Artificial Intelligence (AI) to gain a deeper understanding and further enhance their agility and regility. Organisations are turning to AI as a critical enabler to achieve these goals. AI empowers organisations by analysing large data sets quickly and accurately, enabling faster decision-making and building agility and resilience. This strategic use of AI gives businesses a competitive advantage and allows them to adapt to rapidly changing environments. Failure to prioritise agility and responsiveness can result in increased costs, missed opportunities, competition and reputational damage, and ultimately, loss of customers, revenue, profitability, and market share. Prioritising can be achieved by utilising eXplainable Artificial Intelligence (XAI) techniques, illuminating how AI models make decisions and making them transparent, interpretable, and understandable. Based on previous research on using AI to predict organisational agility, this study focuses on integrating XAI techniques, such as Shapley Additive Explanations (SHAP), in organisational agility and resilience. By identifying the importance of different features that affect organisational agility prediction, this study aims to demystify the decision-making processes of the prediction model using XAI. This is essential for the ethical deployment of AI, fostering trust and transparency in these systems. Recognising key features in organisational agility prediction can guide companies in determining which areas to concentrate on in order to improve their agility and resilience.

description: Le féminisme s’est avéré au fil des décennies un lieu d’élaboration, de partage et de transformation d’idées sans équivoque. Dans tous les mouvements féministes de la planète, c’est à travers un échange d’idées sur la situation particulière des femmes dans différentes régions du monde que le féminisme progresse. Influencées par les critiques sociales provenant des milieux de la nouvelle gauche intellectuelle des années 1960 et de son penchant pour la déconstruction des structures et superstructures qui gouvernent la société, les féministes ont emprunté et adapté plusieurs de ces cadres analytiques qu’elles ont ajouté à leur propre bassin d’approches théoriques. Au Japon comme ailleurs, le féminisme s’est inspiré des grands courants intellectuels pour former une pensée féministe distincte. La présente analyse cherche donc à mettre en évidence les influences théoriques de la nouvelle gauche internationale ainsi que le particularisme national de l’approche déconstructiviste du féminisme japonais à partir de la fin des années 1960 jusqu’à aujourd’hui. Pour ce faire, nous proposons une analyse en profondeur des écrits de trois auteures féministes japonaises prolifiques aux approches déconstructiviste variées. En premier lieu, une attention particulière sera portée aux écrits d’Ueno Chizuko (1948-), souvent reconnue comme l’une des féministes la plus importantes de sa génération, dont l’approche déconstructiviste remet en question la modernité japonaise en abordant les thèmes fondamentaux de la famille, de l’État-Nation, du discours et de l’histoire. En second lieu, les écrits d’Ide Sachiko (1939-), sociolinguiste à la renommée internationale, permettront de mettre en lumière les différences de genre qui caractérisent la langue japonaise, notamment en matière des formes linguistiques de politesse et dans l’usage d’un langage spécifique pour les femmes. Finalement, une analyse de l’oeuvre de Takahashi Takako (1932-) explore la déconstruction du genre au sein de la littérature japonaise en matière d’identification, d’inversion de genre et de maternité.

description: Depuis les 25 dernières années, la prévalence de l’obésité augmente considérablement chez les personnes de tous les âges. Cette tendance inquiétante s’accentue chez les femmes en âge de procréer. Une femme obèse enceinte se prédispose et expose son fœtus à des facteurs de risque importants. En tant qu’infirmière, la possibilité d’avoir à intervenir, auprès de femmes enceintes obèses ou en surplus de poids se présente de plus en plus fréquemment. Cependant, le domaine de recherche sur les connaissances et les perceptions des infirmières sur la femme obèse et son nouveau-né est peu développé. Un devis de recherche quantitative de type descriptif a été utilisé afin d’identifier les connaissances erronées et/ou manquantes des infirmières. Ceci, dans le but de formuler des recommandations visant à améliorer la formation des infirmières en périnatalité. La collecte de données a été réalisée auprès de 76 infirmières qui ont répondu à un questionnaire structuré selon trois des quatre savoirs infirmiers de Carper (1975); soit le savoir empirique, le savoir personnel et le savoir éthique. Les résultats montrent que les infirmières ont davantage de lacunes dans le savoir-science. Au terme de cette recherche, on apprend que les infirmières ne prennent pas suffisamment en considération les complications et les risques possibles lorsqu’elles interviennent auprès des patientes obèses et de leurs nouveaux nés. Par contre, comparativement aux quelques auteurs qui se sont penchés sur les perceptions des infirmières quant à l’obésité, les infirmières de l’échantillon posent tout de même un regard positif sur leurs patientes obèses. Les résultats de cette étude représentent une contribution importante à l’approfondissement des connaissances au sujet des perceptions et des savoirs des infirmières de la femme obèse qui donne naissance. Les recommandations qui en découlent permettront d’améliorer la formation des infirmières en périnatalité et la qualité des soins offerts à ces patientes.

description: Membrane diversity associated with variation in body mass and body temperature of hymenopterans was investigated. Body mass of organisms affects most aspects of their biology, including physiological traits. One trait influenced by mass is metabolic rate, but the basis for its variation among organisms remains unclear. Recent work revealed that membrane phospholipid composition varies systematically with body mass: smaller vertebrates with higher mass-specific metabolic rates have more fluid membranes containing more long chains of polyunsaturated fatty acids (PUFA) and less monounsaturated fatty acids (MUFA). This “membrane pacemaker” theory of metabolism has recently been challenged by a lack of link between metabolic rate and membrane composition. To test this relationship, we have quantified the membrane lipid composition of 22 species of Panamanian orchid bees with a 22-fold range in mass. Results incorporating phylogenetic analysis show significant relationships for 18:1 (MUFA) and 18:3 (PUFA) with body mass that are consistent with the “pacemaker” theory, and unexpected relationships with saturated fatty acids (SFA). Moreover, changes in membrane fatty acid composition with temperature are a strategy in ectothermic poïkilotherms that is part of the “homeoviscous adaptation” model. Here, we report systematic variations in fatty acid composition linked with thoracic temperature excess in North American Hymenopterans, a novel discovery in these heterotherms. These findings are discussed in the context of diet, metabolism and lifespan.

description: To calculate the sensitivity and specificity of multifocal electroretinography (mfERG) in detection of chloroquine and hydroxychloroquine retinal toxicity, 120 eyes of 63 patients were evaluated using the currently recommended diagnostic tests. The results were compared to those of 54 eyes of 28 control subjects. The sensitivity and specificity of mfERG relative to the combination of automated visual fields and optical coherence tomography (the reference test) were calculated to be 87% and 86.5% respectively. However, analysis of the “false positive” cases proved that mfERG was more sensitive than the reference test and the actual sensitivity and specificity values were higher than the results of this study. Reduction of mfERG amplitude was a strong and reliable sign of early retinal toxicity and was correlated with the cumulative dose of hydroxychloroquine. This correlation was not observed with the reference test quantitative values.

description: Imagining one’s physical activity (PA) possible self can lead to increased PA (e.g., Murru & Martin Ginis, 2010). This online experiment examined potential benefits of forming a self-regulatory PA possible self, which involves reflection on a PA possible self image and strategies to pursue this self. This intervention was compared to a standard PA possible selves intervention and a control condition in terms of impact on motivational, self-regulatory, and PA outcomes. Insufficiently active participants (n = 247) completed baseline measures, were exposed to the intervention or control procedures, and then completed outcome measures immediately and at two and four-weeks post-intervention. The mediational roles of action/coping planning in the intervention-PA relationships were explored. Results: ANCOVAs showed no differences on motivational or self-regulatory outcomes; action/coping planning were not mediators. The two intervention conditions, combined, led to significantly greater PA over the four weeks post-intervention than did the control condition (p. = .041).
Is It Best to Have It All: Emotional, Cognitive and Behavioral Consequences of Conflicting Expert Advice on Decision Makers

description: Whether it is in private or professional lives, people are called to make decisions and they tend to seek expert advice. The old adage indicates that more heads are better than one. Receiving more information is often helpful to decisions. However, getting multiple conflicting expert advice might put decision makers in difficult situations. Little is known about their feelings, thinking, and behaviors under such conditions. This research aims to fill the gap and understand the abovementioned consequences of taking multiple conflicting expert advice when making professional (i.e., business or personnel-related) decisions. Using an interview-based qualitative approach, this research sheds light on contextual characteristics where conflicting expert advice may be more beneficial (or harmful), which contributes practical recommendations to improve professional decisions. In sum, this research seeks to verify whether the common wisdom of “more is better” holds up to empirical scrutiny, and suggests that it is “no pain, no gain”.

description: In this thesis, we explored the use of a renewable resource to produce more sustainable polymeric materials. Limonene, a monocyclic terpene existing in many essential oils extracted from citrus rinds, was the renewable monomer investigated. The d-limonene ((+)-limonene) isomer is a major component (~90%) of orange oils from orange juicing and peel processing. Having been used as a flavour and fragrance additive in cosmetics, foods and beverages, as well as a green solvent, limonene is of particular interest in polymerization, because it contains double bonds, which provide the bifunctionality necessary for polymerization. Limonene is also an allylic monomer (CH2=CH-CH2Y), which presents challenges in free-radical homopolymerization and thus, copolymerization was investigated herein to overcome this difficulty. 2-Ethylhexyl acrylate (EHA) and n-butyl methacrylate (BMA) were used in two separate projects, as comonomers with limonene. Using bulk free-radical copolymerization at 80℃, with benzoyl peroxide (BPO) as the initiator, high molecular weight (>100,000) EHA/limonene and BMA/limonene copolymers were produced. Reactivity ratios, important parameters used in the prediction of copolymer composition, were estimated and shown to accurately predict the copolymer composition of subsequent experiments. These can now be used for the application of appropriate semi-batch policies to further enhance limonene incorporation into the copolymers.
From Troubles to Triumph: The Role of Design Culture in Establishing a Design Policy in Northern Ireland

subject: Social design

description: As design policies and national design strategies are becoming more prevalent in developed countries, there is a clear nudge to governments’ improved understanding on the positive value of design and design-led economies. This new context of support and awareness is developing in contrast to the reality that some regional areas continue to operate in troubled economies and societies that place design at the bottom of its priorities for policy making. As a devolved government that operates within the UK, Northern Ireland (NI) has elements of socio-economic deprivation and a troubled history of conflict. While wider research indicates it has the weakest design economy in the UK, there is limited understanding or identification for the reasons behind it. This research uses a grounded theory approach to observe the culture nuances (tacit habits, behaviors, and perceptions) amongst the NI design community and builds a framework of ten recommendations that can inform policymakers towards considering a policy for design in the region. It exposes a design culture that is insular yet resilient and reveals broader perceptions of a society and government that both undervalues and misunderstands design. While most policy labs build upon participatory, collaborative and co-design methods to engage with stakeholders, this research uses grounded theory and inductive reasoning to develop a theory from within a design community, laying the foundations for policy making to begin.
