Abstract:
This paper establishes new Foster-type criteria for a Markov chain on a general state space to be Harris recurrent, positive Harris recurrent, or geometrically ergodic. The criteria are based on drift conditions involving stopping times rather than deterministic steps. Meyn and Tweedie (1994) developed similar criteria involving random-sized steps, independent of the Markov chain under study. They also posed an open problem of finding criteria involving stopping times. Our results essentially solve that problem. We also show that the assumption of ψ-irreducibility is not needed when stating our drift conditions for positive Harris recurrence or geometric ergodicity.

Abstract:
Cette thèse se concentre sur certaines extensions de la théorie des processus empiriques lorsque les données sont Markoviennes. Plus spécifiquement, nous nous concentrons sur plusieurs développements de la théorie du bootstrap, de la robustesse et de l’apprentissage statistique dans un cadre Markovien Harris récurrent positif. Notre approche repose sur la méthode de régénération qui s’appuie sur la décomposition d’une trajectoire de la chaîne de Markov atomique régénérative en blocs d’observations indépendantes et identiquement distribuées (i.i.d.). Les blocs de régénération correspondent à des segments de la trajectoire entre des instants aléatoires de visites dans un ensemble bien choisi (l’atome) formant une séquence de renouvellement. Dans la premiére partie de la thèse nous proposons un théorème fonctionnel de la limite centrale de type bootstrap pour des chaînes de Markov Harris récurrentes, d’abord dans le cas de classes de fonctions uniformément bornées puis dans un cadre non borné. Ensuite, nous utilisons les résultats susmentionnés pour obtenir unthéorème de la limite centrale pour des fonctionnelles Fréchet différentiables dans un cadre Markovien. Motivés par diverses applications, nous discutons la manière d’étendre certains concepts de robustesse à partir du cadre i.i.d. à un cas Markovien. En particulier, nous considérons le cas où les données sont des processus Markoviens déterministes par morceaux. Puis, nous proposons des procédures d’échantillonnage résiduel et wild bootstrap pour les processus périodiquement autorégressifs et établissons leur validité. Dans la deuxième partie de la thèse, nous établissons des versions maximales d’inégalités de concentration de type Bernstein, Hoeffding et des inégalités de moments polynomiales en fonction des nombres de couverture et des moments des temps de retour et des blocs. Enfin, nous utilisons ces inégalités sur les queues de distributions pour calculer des bornes de généralisation pour une estimation d’ensemble de volumes minimum pour les chaînes de Markov régénératives
This thesis concentrates on some extensions of empirical processes theory when the data are Markovian. More specifically, we focus on some developments of bootstrap, robustness and statistical learning theory in a Harris recurrent framework. Our approach relies on the regenerative methods that boil down to division of sample paths of the regenerative Markov chain under study into independent and identically distributed (i.i.d.) blocks of observations. These regeneration blocks correspond to path segments between random times of visits to a well-chosen set (the atom) forming a renewal sequence. In the first part of the thesis we derive uniform bootstrap central limit theorems for Harris recurrent Markov chains over uniformly bounded classes of functions. We show that the result can be generalized also to the unbounded case. We use the aforementioned results to obtain uniform bootstrap central limit theorems for Fr´echet differentiable functionals of Harris Markov chains. Propelledby vast applications, we discuss how to extend some concepts of robustness from the i.i.d. framework to a Markovian setting. In particular, we consider the case when the data are Piecewise-determinic Markov processes. Next, we propose the residual and wild bootstrap procedures for periodically autoregressive processes and show their consistency. In the second part of the thesis we establish maximal versions of Bernstein, Hoeffding and polynomial tail type concentration inequalities. We obtain the inequalities as a function of covering numbers and moments of time returns and blocks. Finally, we use those tail inequalities toderive generalization bounds for minimum volume set estimation for regenerative Markov chains

Abstract:
Long-range dependence in discrete and continuous time Markov chains over a countable state space is defined via embedded renewal processes brought about by visits to a fixed state. In the discrete time chain, solidarity properties are obtained and long-range dependence of functionals are examined. On the other hand, the study of LRD of continuous time chains is defined via the number of visits in a given time interval. Long-range dependence of Markov chains over a non-countable state space is also carried out through positive Harris chains. Embedded renewal processes in these chains exist via visits to sets of states called proper atoms. Examples of these chains are presented, with particular attention given to long-range dependent Markov chains in single-server queues, namely, the waiting times of GI/G/1 queues and queue lengths at departure epochs in M/G/1 queues. The presence of long-range dependence in these processes is dependent on the moment index of the lifetime distribution of the service times. The Hurst indexes are obtained under certain conditions on the distribution function of the service times and the structure of the correlations. These processes of waiting times and queue sizes are also examined in a range of M/P/2 queues via simulation (here, P denotes a Pareto distribution).

Abstract:
The chapter argues that, more than playing catch up with and being determined by technoscientific innovation, law also plays a leading role in the regulation of new technologies by shaping and directing the conditions of possibility for their development and market availability. The chapter charts some of the main ways in which EU internal market law retains its regulatory capacity and efficacy through techniques of negative and positive integration. These techniques centralize the harms or hazards relating to product safety as ‘the’ risks posed by new technologies. Designing regulation and limiting ‘risk’ (through it) marginalizes and obscures other kinds of harms or hazards to which it might pertain. The current regulatory design also depoliticizes, naturalizes, and quells contestation around the approach taken and obscures other potential framings of regulation, such as by human rights and bioethics.

Abstract:
This book offers multiple inroads into thinking with and through the dominant tropes of sexuality. By analyzing particular works of art, each chapter draws our attention to specific aspects of pornotropic (violent and exoticizing) capture that black and brown people must negotiate. These technologies differ, but together, they add to our understanding of the ways that structures of domination produce violence and work to contain bodies and pleasures within certain legible parameters. In addition, the book identifies and analyzes moments that exceed these constraints—the sensual excess that is theorized as brown jouissance. Brown jouissance is a political and philosophical intervention into what constitutes selfhood, knowledge, and fleshiness. The book works through several examples of brown jouissance in the work of Lyle Ashton Harris, Kara Walker, Mickalene Thomas, Xandra Ibarra, Amber Hawk Swanson, Cheryl Dunye, Carrie Mae Weems, Nao Bustamante, Patty Chang, and Maureen Catbagan by dwelling on the analytic possibilities opened by the artwork’s entanglement with the sensual. The sensual, in turn, leads us to imagine possibilities for orienting relationality around queer femininity.

Abstract:
Abstract In this chapter we look at the origins of animal welfare as a societal concern and the interplay between the concept of animal welfare, economics and policy. We firstly propose adjustments to the 'standard view' of the development of animal welfare concerns (which we refer to as the Harrison-Brambell- FAWC (HBF) sequence). For example, we suggest that the role of science in setting animal welfare policy is a more complex process than is sometimes acknowledged. We discuss the application of economics to animal welfare including the analysis of the costs of animal welfare improvements to more recent work on trade-offs relating to animal welfare across the supply chain. Considering this range of uses of economics relating to animal welfare, we identify that the question of how to value animal welfare in economic terms remains unresolved. Lastly, we suggest that the period 1965-2008 may come to be regarded as a 'golden era' for the translation of animal welfare concerns into positive socio-political actions. We discuss a raft of issues which appear to have diminished the position of animal welfare in the policy 'pecking order'. However, societal concern over animal welfare will mean that government and others will need to be cautious of breaching 'red lines'. On a more positive note, the public profile that animal welfare enjoys will continue to provide the opportunity for policy and business innovations to improve animals' lives.

This chapter documents their work on the clock and discusses their choices for implementing modern materials, such as Polyetheretherketone (PEEK) as bushing for gold pivots in the grasshopper escapement. It presents the reasoning for changing Burgess’s original method of driving the clock, which is found on Clock A (also known as the Gurney Clock). Instead of using a weight on a Huygens endless chain with motorised rewind, the team elected to use an unobtrusive weighted arm with electrical rewind to drive the clock.

Abstract:
Working in Lincolnshire in the 1720s, John Harrison (1693–1776) established a unique approach to making accurate pendulum clocks that was born from his experiences in the family business that served country estates in Yorkshire and Lincolnshire. The chapter charts Harrison’s early clock-making practice, inspired by local traditional clocks, and his unique interpretation. He used wood for the frames and most of the wheelwork before key elements of his precision timekeeping crystallised in the making of an estate clock for Brocklesby Park in Lincolnshire. Notably, the elimination of requirement for lubrication formed a solid bedrock for his life’s work in precision in this field. It examines Harrison’s early influences and progression of thinking through documentary evidence and artefacts to introduce the beginnings of his unique approach to precision pendulum clock making.

However, further extension to deduce the load torque demand on drive sprocket during one articulation of the chain is not seen derived in the literature. This paper details this, followed by digital computer simulation including illustration of application of this new procedure to a representative case study.

Abstract:
Using a wheelchair can be a challenging task for people with reduced force and control of muscles of abdomen or lower back. Spinal cord injured (SCI) people are the majority of those who are spending most of the day on a wheelchair and a proper training and chair setup is mandatory to reach a good level of functionality and to avoid harms and side effects. In order to assess the complex motion of a person self-pushing a wheelchair, a motion capture (Mocap) system has been arranged and a group of SCI patients has been acquired in a hospital gym. The Mocap system uses three Microsoft Kinect RGB-D sensors and iPisoft to perform the recording of the 3D motion. The main goal of the research is to provide therapists with a quantitative method to define a preliminary configuration in an objective way once is given the user’s medical conditions and his/her way of using the wheelchair. Working side by side with physiotherapists, the main parameters to be evaluated (e.g. pushing angles) have been identified and algorithms have been identified to automatically extract them from the 3D digital avatar model data coming from the Mocap system. The performance of the patients is then analyzed taking into account the wheelchair setup (e.g. position and inclination of the seat and of the back). The influence of geometric parameters on patients’ motion is analyzed so that design guidelines for configuration can be found. The overall outcome is to maximize performance and minimize side effects and fatigue, providing users with a better experience on the wheelchair.

Abstract:
Washington State began legal cannabis retail sales in 2014. Legalization of adult use cannabis and retail sales may result in more cannabis products in homes and opportunities for accidental exposures among young children. Consumption of cannabis by young children can result in significant adverse health effects. This study examined details of cannabis exposure events involving children under age 12 that were reported to the Washington State Poison Center (WAPC) during January – December 2016. Redacted charts were obtained from the WAPC “Toxicall” database. 50 eligible events were identified. Structured data were used to describe child age and gender and to obtain information about the involved products, route of administration, exposure setting, and clinical effects. Additional information about the exposure event was available in case notes; qualitative methods were used to develop themes and categorize the cases. Most exposure events (62%) were for children ages 0-2, and 26% were for ages 3-5. None of the exposures were reported as intentional. Of those where the source of the product could be determined (N=29) either a parent (n=20, 69%) or grandparent (n=6, 21%) was the most common source. Nearly all (94%) exposures occurred at the patient’s home and involved a single substance (90%). Of those that noted the type (N=13), 85% indicated that the cannabis was obtained for medical purposes. Most exposures were by ingestion (86%), and edibles were the most often reported form (52% of 41 cases with product specified). Nearly all edibles were brownies, cookies, and candies (96%). Baked goods were reported to be both homemade and purchased. Three cases were exposures to cannabidiol (CBD) among children being treated for seizures by their parents: one was the result of a therapeutic error, one an adverse reaction, and one an unintentional exposure. A single child was reported as exposed through breastmilk. Of those with known medical outcomes (N=33), nearly all caused no or minor clinical effects (78%), and nearly all had symptoms for less than 24 hours, most commonly lethargy and drowsiness (50%), but five children were hospitalized for non-critical care and one child with a history of seizures, who was given CBD oil containing THC, required intensive care and intubation. Risk for accidental exposures to cannabis among young children may be increasing as legal cannabis markets become more common. Although most exposures do not cause long-lasting harms, some children can experience significant harm requiring medical intervention. Caregivers of young children are advised to safely store cannabis products in the home so that they are out of reach of children, and to use caution and consult with a healthcare provider about use of cannabis products for medical treatment of a child or adult use while breastfeeding. Clinicians may play a role by screening for household cannabis use among parents and other caregivers, and advising about safe home practices. Continued regulatory approaches to limit exposure, such as limits on THC potency and single-serving packaging designs, may also be useful.

Abstract:
Children work throughout the Lake Volta fisheries value chain. It is commonly assumed most have been trafficked. Research and advocacy has focused on dangers to young boys harvesting fish, and poverty as a driver, precluding attention to harms experienced by non-trafficked children, girls’ experiences and work-education dynamics. More work is needed on the proportions of children who fish and perform harmful work; structural, ecological and historical contexts; young people’s agency in pursuing fishing work; and why attention to trafficking dominates.
