Physical activity behaviour change : supporting cancer survivors to move more.
Creators: name: Webb, Justin
Publisher: name: University of Surrey
Year: 2020

description: This thesis is presented in five chapters. Chapter one offers a review of the literature, divided into six sections. The first section of this chapter provides an understanding of cancer as a disease and a public health concern, including detail on its incidence and prevalence, the biology of cancer and its treatment. The second section of this chapter reviews the literature on physical activity and cancer across the cancer continuum, from prevention of cancer, through cancer treatment, living with or beyond cancer, advanced cancer, and detail on physical activity and cancer mortality and recurrence. The third section of this chapter discusses the determinants of physical activity in cancer survivors, framed within behavioural theories and models to support the identification of intervention opportunities. The identified intervention opportunities are covered in the fourth section. The fifth section of this chapter presents the scope and relevance of the research included in this thesis. The sixth section provides a summary of chapter one. Chapter two presents the first study included within this thesis, a service evaluation investigating the reach, adoption, and impact of a training intervention to influence UK healthcare professionals to give very brief advice on physical activity to cancer survivors. This study also includes an assessment of the predictive value of the behavioural theory upon which the intervention is based, the COM-B model of behaviour (Michie, van Stralen, & West, 2011). Chapter two includes four sections covering an introduction, the method, results, and discussion. Chapter three presents the second study within this thesis. The second study is a randomised waiting list control trial to investigate the impacts of a remote-print based intervention supported by Internet-based tools on the physical activity, self-efficacy, and health-related quality of life (HRQOL) of cancer survivors. The randomised waiting list control trial also includes a cost-consequence analysis. Chapter four presents the third study of this thesis, a process evaluation of the remote-print based intervention supported by Internet-based tools. This process evaluation aimed to contextualise use and perceived usefulness of the intervention, supporting the identification of what works and for whom. Chapter five then closes this thesis with a discussion on the theoretical and practical contributions of the body of research as a whole. This final chapter also includes discussion on how the interventions under assessment influence the identified determinants of physical activity in cancer survivors, and identification of future research possibilities.
The effect of increasing resistant starch content of food starches through chilling and reheating process on postprandial glycaemia and lipidaemia
Creators: name: Alzaabi, Abdulrahman Z H A M
Publisher: name: University of Surrey
Year: 2024

description: Resistant starch (RS) emerges as an important component for modulating postprandial metabolic responses, particularly in those with insulin resistance and type 2 diabetes mellitus. This project focuses on the impact of chilling and reheating on RS content in starchy food, and how these changes might influence nutrient digestion and absorption. RS3, retrograded starch, and RS5, starch-lipid complex, are particularly significant due to their formation during food processing.

description:

description: In vitro experiments demonstrated that chilling and reheating increased RS content across all tested carbohydrates (pasta and potato), regardless of fat content used or the incorporation of cheese (p < 0.001). Interestingly, cheese addition inhibited RS formation, while variations in fat content (15g or 30g) did not affect RS formation in meals despite the tendency toward higher RS amount in the higher fat content (p < 0.001 and p = 0.09, respectively). This manipulation of RS could impact postprandial metabolism, with potential applications in managing metabolic dysfunction.

description:

description: The human trials conducted revealed that chilling and reheating decreased meal- derived plasma triacylglycerol and NEFA levels in healthy individuals following the ingestion of high-fat meals (p = 0.01 and p = 0.041, respectively). Moreover, the addition of cheese prior to chilling and reheating significantly lowered glucose response compared to meals with olive oil in healthy individuals (p < 0.001). The cheese addition also masked differences in glucose and insulin responses between chilled-and-reheated and fresh meals. Notably, the ingestion of pasta meals that underwent chilling and reheating improved insulin sensitivity in overweight and obese individuals with insulin resistance (p = 0.046).

description:

description: Overall, these findings enhance our understanding of the influence of food preparation methods on nutrient availability. They highlight the potential role of RS in dietary strategies aimed at improving metabolic health, underscoring the significance of food processing techniques in nutritional science.
Form as Social Commitment: The art of Giovanni Anselmo during the Anni di Piombo
Creators: name: Mangini, Elizabeth
Publisher: name: Università degli Studi di Milano
Year: 2012

description: In April 1968, concurrent with the early stages of the student movement in Europe, the young Arte Povera artist Giovanni Anselmo installed his first solo exhibition at a Turin gallery. The sculptures shown there were not static objects, but rather demonstrations of invisible concepts like relativity. What emerged in Anselmo‘s first solo show and developed over the ensuing decade was a tactical resistance to the crystallization of his works into a single image or static object. This paper argues that this approach was also central to a critical understanding of the roles of the artist and the viewer during a time of great political foment in Italy and throughout Europe. I explore the relationship of Anselmo‘s sculptural interests to the currency of phenomenology in Northern Italy, the theorization of Arte Povera, in which he figures as a central protagonist, as well as to the socio-political challenges of the 1970s in Italy. Between 1967 and 1978, Anselmo endeavored to reveal tense fullness in empty spaces and to discover latent energy in seemingly inert materials by activating the viewer‘s ability to recognize them as small indications of a dynamic macrocosm. In the context of 1968 and the ensuing Anni di piombo, such macrocosmic glimpses might occasion a broadened worldview, in which the closed perceptual dialectic of self versus world could expand to include other, previously invisible, possibilities. From this expanded point of view prompted by Anselmo‘s presentation of energies, one can begin to understand, and even undermine, man-made ‗invisible‘ systems like government and class. By doing this through the form of the work rather than its explicit content, Anselmo models the notion of an artist using form as social commitment. This mode of working has resonance for many artists today, who may struggle with reconciling their material practices with political allegiances in an increasingly co-opted art market.

Hypergeometric viable models in $f(R)$ gravity
Creators: name: Hurtado, Roger

Publisher: name: arXiv
Year: 2020
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: A cosmologically viable hypergeometric model in the modified gravity theory $f(R)$ is found from the need for asintoticity towards $Λ$CDM, the existence of an inflection point in the $f(R)$ curve, and the conditions of viability given by the phase space curves $(m, r)$, where $m$ and $r$ are characteristic functions of the model. To analyze the constraints associated with the viability requirements, the models were expressed in terms of a dimensionless variable, i.e. $R\to x$ and $f(R)\to y(x)=x+h(x)+λ$, where $h(x)$ represents the deviation of the model from General Relativity. Using the geometric properties imposed by the inflection point, differential equations were constructed to relate $h'(x)$ and $h''(x)$, and the solutions found were Starobinsky (2007) and Hu-Sawicki type models, nonetheless, it was found that these differential equations are particular cases of a hypergeometric differential equation, so that these models can be obtained from a general hypergeometric model. The parameter domains of this model were analyzed to make the model viable.

Bootstrapping Trust Evaluation Using a Trust Certificate Model
Creators: name: Almoaber, Basmah
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2015

description: Trust plays a vital role in the decision to initiate any interaction. Rational agents may use past experiences and other agents’ opinions to decide to trust, but due to the nature of open multi-agent systems, where agents can dynamically join and leave the system at any time, agents may find themselves dealing with complete strangers whom neither they nor their friends have encountered before. This situation forces the agents to choose partners randomly, which significantly increases the risk of encountering unreliable agents. For instance, service requesters may become reluctant to initiate communication with newly-joined service providers. And when the newcomers are service requesters, who are willing to exploit the environment, service providers may also hesitate to start any connection with them. As a result, newcomers are excluded from the competition and old agents lose the possibility of interacting with better agents. In this thesis, we address that issue by creating a Trust Certificate (TC) model in which each agent is equipped with a certificate that works as a reference by providing information about its holder. The information is obtained and stored by the agent itself and is available to other agents who request it to evaluate the holder’s trustworthiness for a potential interaction. The stored information is about the agent’s role in the society and its performance in past interactions. The TC model allows agents to retrieve reputation information and make initial trust evaluations when evidence is unavailable. It also helps agents to avoid the need to make random partner selection due to the information scarcity. We show how this model enhances the interaction process between agents by evaluating it in the context of a simulated multi-agent system.

description: Noticing an increase in the construction of learning spaces adjacent to schools, this research study was designed to find out how teachers are using outdoor classrooms in urban settings to support student success and well-being through experiential learning. Case studies were carried out at four urban school locations. Key elements were touring the sites, and interviewing the teacher participants. An intentional variety of geographic and socio-economic locations were selected as well as a variety of student ages (K-12) and teacher experiences for this project. Despite the wide range of contexts, commonalities were identified between the research sites regarding: understandings of nature as an educational place, supports required to enable learning to take place in nature settings, what we can learn from the land in outdoor classrooms while incorporating Indigenous ways of knowing, what outdoor classroom experiences teachers designed, and how they relate to nature and to their students in these outdoor classroom spaces. During the planning stages of this project, the Covid-19 pandemic was still a concern, and the study also examined how the pandemic influenced the choice to teach and learn outside. Key findings identified four key elements for outdoor experiential learning success from the interview themes: preparation, nature awareness, connection, and regulation. Necessary supports included administrative encouragement, professional development and the reduction of barriers for teachers. Other implications on how to increase outdoor learning opportunities included sharing successes with other teachers, providing supplies, and having nature spaces easily accessible.

Re-Active Vector Equilibrium: A Novel Method of Autonomous Vehicle Navigation using Artificial Potential Fields

Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2015

Artificial Potential Fields

description: The use of potential field based navigation schemes in robotics has been limited by inherent local minima issues. Local minima traps, small passages, unstable motion, and targets positioned near objects all pose major concerns when using potential fields for local vehicle control. This work proposes a new algorithm, "Re-Active Vector Equilibrium" (RAVE) that mitigates many of these issues. The vehicle representation model is expanded to use multiple points subject to potential calculation and the addition of two forces, a velocity dependent "risk force" (F_rsk) and a velocity and direction dependent "tangential force" (F_tan). The vehicle representation model is also expanded from a single reactive point to a series of points that define the vehicle body, providing better and simpler vehicle control. This has the effect of simplifying the required calculations at the cost of increasing the calculation count. The risk force, F_rsk, allows for dynamic adaptation to the immediate environment by acting in opposition to the net obstacle force, and is inversely proportional to the vehicle speed. The tangential force, F_tan, encourages better wall-following behaviour and provides a biasing mechanism to resolve obstacle aligned with target local minima issues.
A Two-Part Study Exploring the Role of Mental Health on Young People’s Sexual Relationships and Behaviours

description: Adolescence and early adulthood (ages 16- to 24-years) are formative years when young people begin to engage in sexual behaviours and relationships. Little is understood about how mental health impacts risky sexual behaviour in this age group. Impulsivity is often thought to be a mediating factor in risky sexual behaviour in adult populations, and impulsivity is suggested to be greater in this young people. This thesis aimed to address this by conducting a two-part project. The first empirical paper addresses the question whether there are any differences in terms of risky sexual behaviour and impulsivity between young people with a diagnosis of borderline personality disorder, young people with any other mental health diagnosis, and young people without an existing mental health diagnosis. Findings from this study indicate that there are no significant differences in impulsivity and risky sexual behaviour between young people with mental health diagnoses, including BPD, and those without. Instead, results showed that impulsivity was the primary indicator for risky sexual behaviour in this age group. The second empirical paper seeks to answer the question how young people with a diagnosis of borderline personality disorder make sense of their lived experiences of sexual relationships. Findings from this second study indicated that emotional dysregulation experienced by the participant led to them seeking comfort by using drugs and alcohol and engaging in sexual behaviours. A second key point from this second study was that heterosexual sex and relationships were a way for the young participant, who identified as non-binary and gay, to fit feel like they fit into a heteronormative society. Implications for future research and clinical practice are discussed.

description: Background: The discovery and development of new medicines requires high-throughput screening of possible therapeutics in a specific model of the disease. Infrared thermal imaging (IRT) is a modern assessment method with extensive clinical and preclinical applications. Employing IRT in longitudinal preclinical setting to monitor arthritis onset, disease activity and therapeutic efficacies requires a standardized framework to provide reproducible quantitative data as a precondition for clinical studies. Methods: Here, we established the accuracy and reliability of an inexpensive smartphone connected infrared (IR) camera against known temperature objects as well as certified blackbody calibration equipment. An easy to use protocol incorporating contactless image acquisition and computer-assisted data analysis was developed to detect disease-related temperature changes in a collagen-induced arthritis (CIA) mouse model and validated by comparison with two conventional methods, clinical arthritis scoring and paw thickness measurement. We implemented IRT to demonstrate the beneficial therapeutic effect of nanoparticle drug delivery versus free methotrexate (MTX) in vivo. Results: The calibrations revealed high accuracy and reliability of the IR camera for detecting temperature changes in the rheumatoid arthritis animal model. Significant positive correlation was found between temperature changes and paw thickness measurements as the disease progressed. IRT was found to be superior over the conventional techniques specially at early arthritis onset, when it is difficult to observe subclinical signs and measure structural changes. Conclusion: IRT proved to be a valid and unbiased method to detect temperature changes and quantify the degree of inflammation in a rapid and reproducible manner in longitudinal preclinical drug efficacy studies.

description: Lithium-ion batteries (LiB) represent state-of-the-art technology in energy storage and power, everything from portable electronic devices to grid-scale energy storage. However, LiB cannot meet future energy demands that require high specific energy and longer cycle life for various rapidly progressing battery applications. Among many other proposed new battery models, Lithium-Sulfur (Li-S) batteries are considered a potential candidate for future energy storage devices due to their significantly higher theoretical specific capacity of 1675 mA h g-1 and high theoretical energy density (2600 Wh kg-1 and 2800 Wh L-1). However, the shuttle effects of lithium polysulfides (LiPSs) and the sluggish reaction kinetics are significant barriers to the commercialization of Li-S batteries. This thesis addresses these challenges through computational and experimental investigations focusing on advanced electrocatalysts. Firstly, density functional theory (DFT) studies on vanadium disulfide (VS2) explored its ability to trap lithium polysulfides (LiPS) and enhance the sulfur reduction reaction (SRR). Results demonstrated moderate LiPS binding and superior electrocatalytic activity of the VS2 (001) facet, significantly lowering energy barriers for LiPS conversion. Secondly, a lamellar stacked VS₂/MoS₂ nanoflower heterostructure was synthesized, combining the conductivity of VS2 with the catalytic activity of MoS2 to effectively mitigate the shuttle effect. Electrochemical testing demonstrates excellent performance for VS₂/MoS₂@S cathodes. It delivers an initial discharge-specific capacity of 1353 mAh g-1 at 0.1 C, and even at a high current density of 1 C, the capacity remains as high as 925 mAh g-1. Finally, a comprehensive DFT study evaluated two-dimensional MXenes as potential electrocatalysts, revealing their moderate LiPS binding affinity and identifying Ta2CO2, Zr2NO2, and Mo2NO2 as promising candidates with lower thermodynamic overpotentials for the SRR. This research provides critical insights into the design of advanced electrocatalysts, ultimately contributing to the development of high-performance Li-S batteries with enhanced efficiency and cycle life.
A Künneth Theorem for Lagrangian Quantum Homology

description: In 1996, Yong-Geun Oh introduced the pearl complex as a means of computing the Lagrangian intersection Floer homology of a monotone Lagrangian with itself. This complex and its homology, the Lagrangian quantum homology, were later studied in detail by Paul Biran and Octav Cornea. We explain the construction of the pearl complex and, under a genericity assumption, prove a Künneth theorem for its homology. The proof consists of two parts: An algebraic part, which is a Künneth theorem for differential graded modules, and a geometric part, whose proof closely resembles the proof of the Künneth theorem for Morse homology. We present the algebraic part at the outset and the geometric part at the end after establishing the necessary prerequisites from local and global symplectic geometry.

description: We revisit long-standing controversies regarding relationships among the all-India rainfall index (AIRI), sub-India summer rainfall variations, El Niño-Southern Oscillation (ENSO), and the Indian Ocean Dipole (IOD) using 120-year sea surface temperature and high-resolution rainfall datasets. AIRI closely tracks with the spatial extent of wet anomalies and with the average across gridpoints in rainy day count. The leading rainfall variability mode is a monopole associated primarily with rainy day count and ENSO. The second mode is a tripole with same-signed loadings in the high-rainfall Western Ghats and Central Monsoon Zone regions and opposite-signed loadings in Southeastern India between. The IOD projects onto this tripole and, as such, is weakly correlated with AIRI. However, when the linear influence of ENSO is removed, the IOD rainfall regressions become quasi-homogeneously more positive, making the ENSO-residual IOD and AIRI timeseries significantly correlated.

Michel de Montaigne. Per una lettura degli Essais

description: Si riflette sullo stile di pensiero degli Essais, in cui, come afferma lo stesso Montaigne «vi è gran libertà di parlare in ogni senso, e pro e contro». Si rileva la capacità del pensatore di conferire un nuovo significato a termini tradizionali, recuperati in accezioni inedite. Emerge per esempio una nozione di forma che sa includere il molteplice senza irrigidirlo nell‟Uno. Ciò che Montaigne ri-fiuta è la concezione tradizionale di forma come essenza rigida, come insieme di tratti o di proprietà; l‟identità del soggetto umano – l‟ humaine condition – è invece una condizione flessibile, cioè aperta a destini divergenti. Il pensiero di Montaigne si può interpretare dunque come un pensiero della flessibilità.

description: The rising global energy demand and worsening effects of climate change highlight the urgent need for clean and efficient energy technologies. Solid oxide fuel cells provide a promising solution by directly converting H2 into electricity with high efficiency while also producing useful heat for combined heat and power applications. However, solid oxide fuel cells still face challenges in cathode and electrolyte resistance, which must be addressed to optimize their performance at intermediate temperatures (600 – 800 °C). Nd1-xBaxCo0.8Fe0.2O3-δ (SS-NBCF) prepared through solid-state synthesis is investigated, focusing on how Ba2+ doping affects the crystal structure, phase composition, electrical conductivity, and oxygen reduction reaction activity. Powder X-ray diffraction shows that higher Ba2+ doping levels lead to the formation of secondary phases. Phase-pure SS-NBCF25 shows an electrical conductivity of 674 S/cm at 700 °C and an area-specific resistance of 0.11 Ω cm2 at 750 °C in air under open circuit conditions. Tape casting is used to fabricate a thin, tri-layer (porous/dense/porous), La0.8Sr0.2Ga0.8Mg0.2O3-δ (TL-LSGM) electrolyte. Infiltration of TL-LSGM with a NdBaCoFeO5+δ (I-NBCF) cathode and Ni-Gd-doped-CeO2 (Ni-GDC) anode yields solid oxide fuel cells with an ohmic resistance (Ro) of 0.11 Ω cm2, polarization resistance of 0.33 Ω cm2, and peak power density of 400 mW/cm2 at 750 °C under 200 SCCM H2 flow at the anode and atmospheric O2 at the cathode.

Cellular differentiation

description: During cellular differentiation, gene expression is globally regulated through changes in the epigenome. How a single genome can give rise to a diversity of cell and tissue types remains a complex area of investigation, and here we sought to explore the molecular regulation of gene expression during the differentiation of skeletal muscle cells from committed myogenic progenitors. Using a systematic and integrated analysis of global transcriptional and epigenetic data, we characterized the regulation of gene expression in differentiating myoblasts and found that muscle-specific gene expression is regulated through differential activation of tissue-specific regulatory DNA elements by the myogenic transcription factor MyoD. In addition, the genome-wide localization of MyoD, and the mechanisms underlying its function in transcriptional regulation, varies between myogenic progenitors and differentiating myoblasts. Our study explores the recruitment and function of MyoD at regulatory elements of target genes and additionally describes a novel role for ligand-inducible signaling in the regulation of MyoD function and ultimately in myogenic differentiation.

description: For many decades now, there has been a general decline of traditional indicators of religiosity in both Quebec and British Columbia. New generations are being born and raised in much more secular social contexts than in years past. However, this general trend of decline masks many differences between the two Canadian provinces, and does not imply a complete disappearance of religion from society. Certain groups of believers have been able to maintain their numbers and levels of practice. Over the last 15 years, these two worlds of the secular and the religious seem to have been confronting one another more and more, evident in public debates and individual representations. The emerging framework of religious polarization offers conceptual tools to better grasp this dialectical dynamic in advanced Modernity. By analyzing recent statistical data on individual religious practices, we examine the extent to which this cleavage between the religious and non-religious is developing among younger generations in two distinct religious and social contexts: those of Quebec and British Columbia. Depuis plusieurs décennies, on note un déclin des indicateurs traditionnels de religiosité parmi les populations générales du Québec et de la Colombie-Britannique. De nouvelles générations naissent et grandissent au sein de contextes sociaux bien plus sécularisés qu’auparavant. Toutefois, cette tendance générale de déclin masque plusieurs différences quant aux deux provinces canadiennes, et n’implique pas nécessairement une disparition totale du religieux de la société. Certains groupes de fidèles connaissent une vitalité importante quant à leurs pratiques et leur nombre d’adhérents. Au cours des derniers quinze ans, ces deux mondes du séculier et du religieux semblent se confronter et se cristalliser dans les débats publics et médiatiques, ainsi que dans les représentations des individus. Le cadre théorique naissant de polarisation religieuse nous offre des outils conceptuels afin de mieux saisir cette dynamique dialectique en modernité avancée. En analysant des données statistiques récentes en ce qui concerne les pratiques religieuses des individus, nous examinons si ce clivage entre religieux et non-religieux se développe de plus en plus parmi les nouvelles générations dans deux contextes sociaux et religieux distincts : ceux du Québec et de la Colombie-Britannique.
"Community has got a hell of a lot weaker": working class and precariat men's search for wellbeing through social prescribing
Creators: name: Mars, Adam
Publisher: name: Lancaster University
Year: 2024

description: Despite the growing interest in social prescribing in recent years, both
 in policy and research, little is known on the experiences of men who are
 referred to it. Even though recent evidence suggests that men are referred
 less to social prescribing, there is very little coverage in the
 literature on social prescribing that specifically focuses on men; this
 thesis therefore provides a much-needed and timely exploration into men’s
 journey through the policy. Through semi-structured interviews with
 working class and precariat men (n=14) who have been referred to and used
 social prescribing in the North of England, and link workers (n=11), the
 thesis explores men’s experiences and perceptions of social prescribing.
 In so doing, it aims to explore claims that social prescribing can tackle
 health inequalities and connect people to what matters to them. As a
 result, this thesis examines if and how social prescribing connects with
 working class and precariat men, enquiring as to whether it provides men
 with experiences, access to social capital, resources and relationships
 that contribute to health and wellbeing. The thesis concludes that men’s
 engagement with social prescribing has mixed success in connecting men to

description: This article reappraises the Irish-language autobiography, Peig, as a unique account of the experience of life and work by a woman of the rural Irish speaking subsistence class. Peig is a seminal Irish language text, both as a depiction of class and gender-based conflict, and as an Irish language work that describes intersectional issues of justice, labour, rights and femininity from childhood to old age. I examine the narrative through the lenses of home, poverty, housing, work, marriage, children, friends, foes and loss. Peig depicts great resilience in the face of structural inequalities and localised injustice. The sustaining nature of intergenerational female friendships plays the central role in Peig’s account of her life. Arguing that the text belongs to the shared histories of women across the world, from China to the Middle East and Africa, I conclude that Peig is one of the most emotionally rich books in modern Irish. The article opens new ground in examining the question of class in Irish language literature, concluding that its universal themes continue to resonate in a contemporary multi-ethnic Ireland.

description: The Atlantis II Deep is a location of modern submarine hydrothermal activity along the slowly spreading Red Sea rift axis. Venting of high-temperature hydrothermal fluids, similar to those associated with black smokers, takes place in a brine pool and has led to the accumulation of 90 Mt (dry, salt free) of stratiform, metalliferous sediment. The conditions of mineralization are unique in the modern oceans, but have been widely suggested as a possible analog of some important ancient stratiform base metal ore deposits. This study shows that many of the proposed genetic models for these ancient deposits may be highly simplified and do not take into account rapid diagenetic transformations, widespread non-equilibrium processes, and many other aspects of metal deposition. Sediment cores of the Atlantis II muds were last studied more than 30 years ago. High-resolution sampling and careful re-examination of the mineralogy and geochemistry of the sediments, using modern analytical techniques has significantly improved the understanding of the different processes responsible for the formation of the finely layered metallifeous sediments. The geochemistry of the individual layers is controlled by highly variable detrital, hydrogenic and hydrothermal input. Primary depositional pathways from the brine pool are the main control on basin-wide metal distribution (e.g., increasing Cu/Zn away from the vents) including variable enrichment in trace metals via scavenging from the brine pool and from the enriched pore waters. Cu and Zn have been deposited not only as sulfides but also with poorly crystalline Si-Fe-(oxy)hydroxides. A significant proportion of the original non-sulfide Cu and Zn are diagenetically transformed into sulfides, but also carbonates and clays, in large part reflecting sulfide deficient pore waters. Negative δ34S values, previously unrecognized in the sulfide- and metal-rich units, indicate a source of bacteriogenic sulfide. Syn-diagenetic processes also appear to have been responsible for the sharp laminations in the sediments, as well as distinctive zoning of carbonate and clay minerals around the vent source. The early diagenetic transformations observed in the Atlantis II Deep may not be preserved in the ancient rock record but nevertheless have important implications for metal deposition in some of the world’s largest and richest base metal ore deposits.
Corporate Events and Stock Price Reactions: The Impact of Investor Sentiment
Creators: name: Malekpourkolbadinejad, Soheila
Publisher: name: University of Surrey
Year: 2020

description: This thesis studies the impact of firm-specific investor sentiment on stock price reactions to events; earnings surprises, dividend changes, and credit rating changes. The first empirical chapter establishes that firm-specific investor sentiment is a key determinant of price adjustment in the context of an earnings surprise. This chapter demonstrates that the price impact of firm-specific investor sentiment is not moderated by market-wide investor sentiment; and it is greater for firms announcing negative earnings surprises and firms facing uncertainty in valuation. Further, this chapter provides evidence of mispricing and return reversals over the days following earnings surprises. The second empirical chapter investigates the impact of firm-specific investor sentiment on stock price responses to dividend changes. This chapter establishes that bullish investor sentiment moderates the negative price impact of a decrease in dividends. It suggests that the moderating impact of bullish investor sentiment is most marked for hard to value and difficult to arbitrage firms. Furthermore, it highlights that the impact of bullish investor sentiment is temporary as it reverses in a short period following dividend change announcements. The third empirical chapter explores the role of firm-specific investor sentiment in stock price formation around credit rating changes. This chapter provides evidence that investor sentiment has a significant impact on stock price responses to rating downgrades. It shows that the price impact of investor sentiment is most pronounced for speculative-grade firms and firms experiencing direct rating downgrades. Moreover, it indicates that mispricing due to the impact of investor sentiment reverses over the post-announcement period. Overall, the findings of this thesis provide strong evidence that investor sentiment towards individual firms plays an important role in stock pricing around corporate events.

Dalla fenomenologia all’ermeneutica.  Il pensiero analogico di Bachtin come strategia  epistemologica
Creators: name: Pellizzi, Federico
Publisher: name: Università degli Studi di Milano
Year: 2012

description: Si presenta la filosofia etica ed estetica di Michail Bachtin nel suo spazio originale tra fenomeno-logia ed ermeneutica. Riflettendo sulla peculiare logica "analogica" proposta dal pensatore russo, si mostra come tale pensiero riesca a porre in relazione soggettività e mondo, unicità della per-sona e spazio complesso della cultura.

Three essays in health economics
Creators: name: LIU, XIAOMING
Publisher: name: University of Surrey
Year: 2022

description: This thesis contains three chapters on social and economic determinants of health. The first chapter investigates the causal effects of education on mental health. To address the endogeneity issues of education, the study uses Instrumental Variable strategy where actual years of education are instrumented by cohort-specific compulsory schooling years and its interaction with various childhood condition dummies. The estimates on the causal effects are sensitive to the choice of additional instruments. While majority of estimates suggest that there are no or only limited causal protective effects of education on mental health, the possibility of negative effects remains. The strong positive association between education and mental health could be explained by unobservable individual characteristics that affect education and mental health in the same direction.
description: The second chapter studies whether more generous maternity leave protection in duration and payment can help decrease the incidence rates of pregnancy loss or termination (induced abortion, miscarriage and stillbirth) in low- and middle-income countries. Using a quasi-Difference-in-Differences approach, the study provides some evidence that increasing the generosity of maternity leave has the potential to reduce, in particular, the probability of induced abortion or miscarriage. The effects are stronger for Asian mothers who are working, mothers who have higher educational attainment and prestigious occupations, and mothers who were aged below 21 or above 30 at the realization of pregnancy outcomes.
description: The last chapter explores how early life exposure to adverse shocks negatively affects the anthropometric outcomes of the second generation in Sub-Saharan African countries. The study reveals compelling evidence that mother’s experience of negative rainfall shocks, particularly excessive drought, from in-utero to early adolescence significantly increases the probability that their offsprings suffer from impaired growth during early childhood. The effects are mainly driven by households residing in the rural areas and children who are located at the lower end of anthropometric distribution. There is also evidence that mothers’ early life experience of negative rainfall shocks led to disadvantages in a variety of welfare outcomes persisting into marital households, which potentially contribute to next generation’s underperformance in early life growth measures.
