This portfolio of published research contains nine papers and assesses the life cycle environmental burdens of energy technologies and buildings. Several analytical tools were used but these all fall under the umbrella of environmental life cycle assessment (LCA), and include energy analysis, carbon appraisal and the consideration of other environmental issues. The life cycle of all products starts with an assessment of embodied impacts. The current author has completed significant research on the embodied carbon of materials. This includes the creation of a leading embodied carbon database (the ICE database) for materials which has been downloaded by over 10,000 professionals and has made a significant contribution to knowledge. This portfolio of work includes analysis on methods for recycling in embodied impact assessment and LCA. This is an influential topic and therefore appears in two of the publications. The ICE database was applied by the current author to over 40 domestic building case studies and an embodied carbon model for buildings was created from these. The latter was used to provide benchmark values for six types of new houses in the UK.The portfolio of work then progresses to full LCA of energy systems. LCA is used to assess the embodied impacts versus operational impacts of 11 kV electrical cables. In this case embodied impacts were not significant and preference should be given to reducing electrical losses in the cables. The tool of LCA was then applied to a national electricity network. It revealed that Lebanon had a particularly poor centralised electricity network that was both unreliable and unsustainable with high impacts in all environmental categories. The final paper in this portfolio is on Building Integrated PV (BIPV) and brings together all aspects of the current author’s work and knowledge. It considers embodied burdens, electricity generation and BIPV can replace roofing materials.

Over the last fifty years Western Christianity has been criticized as a cause and enabler of Earth's ecological crisis. This criticism is based on the conclusion that Christianity promotes a spiritual-material dualism and that the material side of life has little sacred value. It is also based on the observed hesitancy of many Christians to embrace modern scientific understandings of creation, especially evolution. Some Christian writers have responded by accepting modern cosmology and evolution, and advocating for a sacramental creation spirituality, oftentimes supported by fresh readings of earlier Christian writings. This dissertation looks at Maximus the Confessor (c.580-662 CE), Nicholas of Cusa (1401-1464 CE), and Teilhard de Chardin (1881-1955 CE). Teilhard attests to an experience of natural sacrament in perceiving an increasingly transfigured creation, meaning the glory of God is ever more perceptible as a timely conscious insight into creation and as an emergent aspect of cosmogenesis and evolution moving toward Christ-Omega, the end and fulfillment of all creation. The teachings of Maximus readily support this sacramental view of creation by affirming a universal, ontological, and "real" presence of the Logos of God. A theological insight of Nicholas's doctrine of learned ignorance is that the Christian God always incarnates, transfigures, fulfills, and exceeds the entire cosmos. Together the teachings of Maximus and Nicholas support Teilhard's call for a theology of a Creator God robust enough to encompass the most expansive and complicated propositions about creation made by science, while remaining as close as the real presence of Christ in the Eucharist. The integrated teachings of these three figures suggest an ontological consecration of creation. This consecration inspires sacramental experiences of God in and through creation that complement the sacramental experience of Christ in the Eucharist. Over the evolutional time frame, these sacraments converge as one and the same sacrament at Christ-Omega. The complementary and ultimately convergent relationship between these sacramental experiences supports the ethical conclusion that just as one receives and responds to Christ present in the elements of the communion table, so one ought to receive and respond to oneself, one's neighbors, and all creation as the universal consecrated neighborhood.

Wastewater treatment plants (WwTP) act as the principle buffer between anthropogenic sources of Silver Nanoparticles (AgNPs) and environmental targets. AgNPs, given their effective anti-microbial properties, have the potential to negatively impact WwTP processes and organisms within the natural environment. A clear understanding of the fate and transport of AgNPs as they pass through WwTPs is crucial in evaluating AgNPs impacts for WwTP process, the natural environment and in the development of a comprehensive environmental risk assessment for AgNPs. The main aim of this thesis was to carry out an analysis on the fate, transport and transformation of AgNPs through WwTP relevant filtration medias in order to understand more about the toxicological implications for both WwTP processes and receiving environments. AgNPs were synthesised in-house, via an in-situ reduction method, which produced a homogeneous dispersion of nanoparticles of average particle diameter 9.98nm, with a standard deviation of 3.11nm. Column studies and adsorption isotherm experiments were conducted to investigate the fate and transport of silver nitrate, AgNPs and bulk silver across media beds of quartz sand and granulated activated carbon (GAC), both chosen for their relevance in wastewater treatment protocols. TEM imaging and EDS analysis was employed to characterise the AgNPs physically and elementally within the column influents and effluents. An original contribution made to the existing knowledge on AgNPs is that in contrast to bulk silver and silver nitrate, uncoated AgNPs were observed to be highly mobile through the quartz sand media. This high mobility was in contrast with the prior expectation that van der Waals forces of attraction between the positively charged AgNPs and the negative charge of the silica surfaces within the sand bed would lead to some measure of retention within the column matrix. The resulting high mobility of the AgNPs was attributed to particle surface contamination of boride ions originating from the reduction agent used during the synthesis process. This highlights (and reinforces) the importance of better understanding on the implications of the various methods of synthesis and use of capping agents for AgNPs characteristics and the impact this has on fate and transport. AgNPs were also noted to have been significantly altered after their passage through the quartz sand media, with up to 83% of the sample increasing in size, from 9.98nm to an average of 18.26nm and a maximum of 144nm. Particle size measurements were made using the measuring tool available in the GNU Image Manipulation Program (GIMP). This size increase was attributed to the formation of nano-alloy clusters with residual gold and iron compounds, naturally present within the sand bed. In the case of silver-gold alloy clusters, this is expected to exhibit positive implications for future environmental fates of the resulting AgNPs, where the presence of gold in alloy clusters has been observed to significantly deactivate AgNPs silver ion release. In contrast to the sand, it was observed that the GAC was an effective absorber of AgNPs. However, this was observed to be a size dependant relationship, where the GAC was not observed to be effective for adsorption of bulk silver at particle sizes of 300 – 800nm. In this thesis, in addition to the experimental work, a novel, low complexity technique was developed for the detection and quantification of AgNPs in laboratory aqueous solutions. This protocol utilises a laboratory bench top photometer and gave AgNPs concentration results that reliably and accurately reflected that of ICP-MS and ICP-OES results within a detection range of 0.01 and 20mg/L; where the correlation coefficient between the instrument absorbance response and ICP-MS/OES concentration (at 450nm) was R2 0.994.

The crabs-in-a-barrel (CIB) mentality—a specialized form of incivility that occurs among members of the same ingroup (i.e., intragroup incivility)—is an understudied yet destructive and consequential intragroup phenomenon. As previous studies on the CIB mentality among the Black community have primarily focused on targets of the deviant behavior, this study trailblazed by serving as the first to employ a mixed methods design to investigate the environmental, perceptual, and affective antecedents of instigated Black-on-Black (B-o-B) incivility in the workplace. More specifically, the present study adopted a social-interactionist approach to investigate whether various aspects of work climate (i.e., institutional discrimination, interpersonal prejudice, and competitive work climate); affective states (i.e., emotional taxation); and workgroup composition factors (i.e., perceived collective and competitive minority threats) were positively associated with instigated B-o-B incivility in the workplace. To that end, a cross-sectional design was employed with a U.S. based sample of 523 full-time Black professionals across various organizations and industries. The proposed hypotheses were tested using logistic regression analyses. Overall, the results showed that collective minority threat and experienced incivility were the most consistently significant predictors of instigated B-o-B incivility in the proposed model—with experienced incivility showing the greatest effect on the outcome variable between the two. Moreover, participants reported that there were 10 primary reasons and/or justifications for acting uncivilly towards another Black employee at their job within the past year. This study provides further support and validation to the notion that the CIB phenomenon represents another variant of the workplace incivility construct. Additionally, this study broadens the workplace incivility discussion and research stream by offering unique insight into the perspectives of racial minority instigators of uncivil behavior at work. The results hold considerable implications for practitioners and organizations seeking to better understand, and address, the issue of intragroup incivility in the workplace—particularly as it relates to Black professionals. Theoretical implications and directions for future research are also discussed.

This thesis contributes to a growing literature on identity and the home. The study's findings enrich understandings of the way people organize the material culture of their homes, and the way objects and practices are drawn into their self-storying. The study reveals the agency in homemaking as a creative practice and highlights the particularity of homemaking experience. It expands the context for understanding the creative work of designing and producing the contemporary home. Home is a key site of intensive consumption and emotional investment in identity. Possessions in the home and in our interactions with them are integral to our experience and construction of who we are in the world. We make our interior landscape visible to ourselves and onlookers through our choice of objects, arrangements and practices. And yet insight into the lived experience of everyday homemaking is elusive. This calls for empirical research to engage directly with the subjective world of individuals. My thesis examines an archive of rich experiential data gathered in informal conversations conducted with homemakers in twenty-five middle-class London homes. Their narrations of subjective experience have been used to explore how people think and feel about their homes, and how and why they arrange certain things in certain ways within those homes. Identity is understood as a storied accomplishment and homemaking is formulated as a means of organizning experience. Material is part of self-representation and is regarded as a narrative resource. A reading of narratives and images in the light of this conceptualisation reveals the meaning in the object and the object in narrative. The theses demonstrates the endeavour of homemaking as a form of creative production that is empowered by individual agency and fuelled by storying interaction.

The University of Manchester, PhD by Published Work, 2018 For several reasons, small and medium enterprises (SMEs) are an important group of firms. In most market economies SMEs contribute significantly to wealth and job creation, economic growth, and product and service innovation. At the same time, SMEs are said to produce environmental impacts that are significant and that need managing and regulating. Their importance, from an economic and environmental perspective, is reflected in the fact that SMEs have become an established subject for research, with a distinct area of analysis focusing on how they manage their environmental impacts. Despite considerable interest in this area, aspects of their behaviour are in need of further examination, for there are still misunderstandings and gaps in knowledge. An area where gaps exist is how SMEs respond to different forms of environmental regulation (e.g., command-based or market-based approaches) and different forms of regulatory pressure (e.g., such as those pressures from civil society that might induce compliance-related activities or market forces that might flow through, and affect, the value chain). Why the gaps? On the one hand, and generally speaking, a common claim among those who have considered issues affecting smaller firms is that regulation is an important driver of environmental behaviour. There is a well-documented set of linked claims and empirical findings that smaller firms tend to be motivated by compliance with regulatory standards, yet owing to their scarce resources can find themselves hovering on the edge of compliance. Typically, SMEs will attempt to do no more than the law requires of them. They tend not, as it were, to go beyond compliance. Of course, this is an important observation - one that might say much, even if indirectly, about the motivations and intentions of smaller firms. It might indicate that SMEs, rather than addressing environmental issues, are more concerned with making cost savings and efficiency gains, or with satisfying the requirements of customers over such matters as product or service quality and delivery. While significant, there are at least three reasons why this view remains incomplete as an explanation for the interaction between SMEs, regulation and the environment. Firstly, this view tends to over-homogenise smaller firms. By treating them as a standardized group, the inference is that SMEs view and respond to regulation - i.e., they are all driven by regulation - in a broadly similar way. Secondly, it says little about how and why regulation drives behaviour. Claiming that regulation drives behaviour is helpful, but the claim is unduly narrow and leaves several important questions. In what ways does regulation drive behaviour? Does regulation drive all smaller firms in the same way? Thirdly, and finally, it suggests that different forms of regulation drive SME behaviour and that different forms of regulation drive this behaviour in broadly similar ways. That is, it is incomplete as it lacks appreciation of the widening scope of regulation and governance, and the nature of smart mixes of regulation. It fails to properly consider whether and how SMEs might respond differently to command-based regulation, market- or information-based measures, or self- or so-called civil regulatory pressures. On the other hand, and again in general terms, while those who have examined regulation have looked at how it can influence firms, they have tended to pay too little regard to how firms of different size may respond to different approaches or to how the factors and characteristics relating to size may shape the effectiveness of regulation. SMEs particularly are often discussed as an unusual sideshow that might raise different issues in relation, say, to the impacts of regulation on performance or innovation. That we often pay too little regard to how firms of different size may respond raises difficulties, particularly given our increasing understanding that there is no guarantee that a particular instrument will work in all situations. In other words, we are becoming more aware of the fact that the effectiveness or ineffectiveness of regulation is likely to be context-sensitive, and that the size of the enterprise is likely to be an important determinant of context. This thesis does take, and provides evidence for, the view that the organisational context is crucial to understanding how regulation functions. The thesis does not claim to provide all answers, but it does adopt the position that, in aggregate terms, a firm's size, or the factors that can be associated with size (e.g., resources, skills, knowledge, visibility, profile, stakeholder relations), and related factors concerning a firm's mind-set, can affect two things; first, the types of regulatory influences that may affect organizational behaviour and, second, how firms will respond to those influences. By focusing on SMEs, the thesis in some ways reinforces the dominant view that regulation is a driver of behaviour. Nevertheless, it goes much farther than this by showing, both theoretically and empirically, that there are important differences across SMEs and that these differences determine how and why they respond to regulation. It extends the common view by showing how SMEs differ not only in terms of the types of regulatory influences that shape their behaviour, but also in terms of how they react to these different influences. The emerging picture thus shows that the responses of firms are determined by their particular characteristics. The term used in this thesis is 'receptive capacity', which is shown to be a composite measure that includes the capabilities (e.g., resources, skills, knowledge) and orientations (e.g., views) of firms. It is suggested here that the range of receptive capacities across firms is enormous, since no two firms will be identical. Yet, it is argued - and demonstrated - that firms can be grouped according to certain identifiable characteristics, and that these groups of firms will respond to regulatory pressures in broadly similar ways; that is, there are groups of firms that have broadly similar resources and broadly similar worldviews. Thus, as well as suggesting that differences can be found at the micro level, it is demonstrated that there are sufficient commonalities across some firms that we can understand them as groups - groups of individual firms with some common characteristics. In conclusion, it is the differences across firms that provide us with a more sophisticated view of how SMEs are influenced by, and respond to, regulation. It is the nature of differences that is the main contribution of this research to both the fields of regulation and organisational and management studies. It is suggested finally that these differences have implications for how we design regulation, for how we may expect regulation to work or indeed not work, and for issues such as regulatory complexity and smart mixes.

This study focuses on the analysis of collective meaning associated with secondary school-teachers' and outdoor practitioners' beliefs about the value of outdoor education in the city-state of Singapore. A phenomenographical approach was employed to map the qualitatively different ways in which people understand, perceive, or experience various aspects of outdoor education. By conducting in-depth interviews with school-teachers and outdoor practitioners (n=11), a range of beliefs about the value of outdoor education were revealed. Through a phenomenographic analysis framework, three conceptions were identified that detail the participants' collective meanings of the value of outdoor education; namely (a) belief in the value of outdoor environments in providing affordances for authentic, realistic learning, (b) belief in its value in fostering social emotional growth, physical and mental robustness, and (c) belief in the value of outdoor education as preparation for students' futures. A secondary research question considered the factors that influence the beliefs of the two sets of actors, teachers and outdoor practitioners, who are the focus of this study. The analysis and discussion focus on the context and meaning of the values ascribed to outdoor education as well as the factors that influenced the beliefs. The findings indicate that school-teachers and outdoor practitioners have strong beliefs about the value of outdoor education. This strong intrinsic belief is constructed through 'sense-making' of their own experiences in the outdoors. This suggests that there is value in investing in the continuing professional development of school-teachers and outdoor practitioners in their outdoor education practice, so that this increased capacity in their complementary roles can bring about the added value of outdoor education to students. Several recommendations for policy, practice as well as further research in the field are offered.
