Abstract:
Dance balls, masquerades, and street carnivals functioned as frontier spaces of otherwise reprehensible encounters between people of different gender, race, and class. I examine dance as a dense point of contact in nineteenth-century Cuba by showing how dance served ruling elites as a disciplining instrument to enforce social and legal boundaries, and was simultaneously used by colonial subjects as a tactic of survival to navigate these barriers. Because dancing lent itself to situations of intimacy and mis-recognition, it challenged Cuban ruling elites’ efforts to police dancing bodies. Dance is offered as a useful methodological venue to illuminate the predicament of the colonial state in governing colonial subjects and bodies. I offer the case of colonial Cuba as a contribution to the study of contact zones and colonial intimacies in Latin America and the Caribbean, in a much-needed examination of the relationships between imperialism, sexuality, and the governance of dance.

Abstract:
An interpretation of frontier texts must respond to the demand by Gesa Mackenthun and other scholars that “empire be added to the study of American culture.” As written by authors like Frederick Jackson Turner, who placed themselves on the colonizing side of the frontier, these texts described the frontier as “the meeting point between savagery and civilization” where European immigrants became “Americanized, liberated, and fused into a mixed race.” Here was forged a “composite nationality for the American people.” Such texts with their understanding of the “Indian frontier ” as a “consolidating agent in our history” which developed “the stalwart and rugged qualities of the frontiersman,” helped to construct the American identity as the “imperial self” with its implicitly patriarchal, Eurocentric, and colonial assumptions. Describing the frontier as a “military training school, keeping alive the power of resistance to aggression,” such texts failed to acknowledge the aggressive acts that seized the land from its original inhabitants.

Abstract:
Abstract This paper considers the case of an introduced species that resides in what is now a jointly managed national park in the north of tropical Australia. Banteng (Bos javanicus) are a peculiar feral nonhuman animal in that they constitute a potential environmental threat within the domestic conservation goals of the park, but they also hold the prospect of being a major genetic resource in the international conservation of the species. Thus, perspectives on the use and management of these animals are varied between different actors in the park landscape, and are subject to fluctuations over time, especially in response to wider social and political circumstances. This paper argues that seemingly objective views of these animals are actually a series of subjectivities, which have less to do with any concrete aspects of the animals themselves and more to do with the way that particular people orient themselves toward, and within, the landscape.

Abstract:
This article examines the separate epistemologies of anthropology and neoclassical economics, suggesting that both epistemologies are tied to and represent ethical stances. After discussing the differences between morality and ethics, it suggests that the epistemologies of both disciplines are rooted in colonial encounters. Although numerous states and empires had previously encountered populations on their peripheries, the European colonial encounter of the seventeenth, eighteenth, and nineteenth century was uniquely on an industrial scale, creating new epistemological and ethical problems, out of which both economics and anthropology emerged. The global episteme and ethical stance of anthropology in its engagement with diversity now has as its frontier an engagement with powerful institutions in the business world.

Abstract:
Located in Northwest Greenland, the Thule region is a remarkable frontier zone. This article focusses on the undecided nature of the frontier in both time and space. The article explores the unstable ground upon which ‘resources’ emerge as such. The case is made in three analytical parts: The first discusses the notion of commons and the implicit issue of spatiality. The second shows how the region’s living resources were perceived and poses a question of sustainability. The third centres on the Arctic as a ‘contact zone’; a place for colonial encounters and a meeting ground between human and nonhuman agents.

Abstract:

An unavoidable feature of humanitarian fieldwork is the day-to-day witnessing of injustice, and the suffering of vulnerable people and communities. The existing psychological and sociological research on aid workers largely focuses on the personal impact of their exposure to suffering and injustice, rather than the actual witnessing experience. The focus of this research is to understand the lived experience of field-workers, how they construct witnessing, and the factors that shape and mediate this experience, in particular the role of the Médecins Sans Frontières (MSF) principle of témoignage [speaking out]. The process of meaning making, and the impact of challenging experiences on field-workers, is also considered. The research method predominantly employed narrative inquiry. Twelve experienced MSF staff were interviewed to elicit personal stories about their role as witnesses. The research findings suggest that for those that daily witness suffering, it is an immediate, direct, and intimate experience. There is a reciprocal relationship with the patient or communities, and an entangled empathy mediates this relationship, and its expression. A strong ethic of care is central to the human encounter. The principle of témoignage, and its call to speak out, or engage in social action, is significant in giving direction to witnessing. Research participants often experienced extreme conditions. Impacts such as fatigue, aspects of burnout, a lack of effective coping strategies, and self-care skills were observed. The quality of MSF as a holding environment for witnessing and meaning making is explored. Practice recommendations are made in terms of organizational implications, leadership, and psychosocial support.

Abstract:
Mes recherches se concentrent sur le travail des artistes plasticiens qui pratiquent l'installation dans les îles francophones de la Caraïbe. Ces îles composées des Antilles (Martinique, Guadeloupe, Saint-Martin ainsi que leurs dépendances administratives) et de la République d’Haïti, sont des terres où la rencontre, le métissage et la Créolité consolident la relation permanente que les populations entretiennent avec leurs différentes genèses, aux ramifications multiples et aux origines transfrontalières.Dans ce contexte, l’installation artistique, qui est située au confluent d’une infinité d’explorations esthétiques grâce auxquelles règles et formes furent remises en question de manière définitive au cours du XXe siècle, se présente sur le mode d’une pluridisciplinarité qui, aujourd’hui, fait autorité dans de nombreuses disciplines. Fruit de rencontres, d’imprégnations, elle est aux seuils, aux confins d’une infinité de frontières géographiques, sociales, politiques, culturelles, où la marge qui sépare le spectateur de l’œuvre d’art se dissout, s’obscurcit, s’estompe et s’évanouit. Cette dissolution significative des frontières entre les arts se manifeste dans de très nombreux champs : l’installation est un phénomène révélateur de cette dissolution qui, dans la Caraïbe francophone, prend une teneur spécifique.Dans l’espace archipélique, la question de la frontière est omniprésente. Elle mêle des problématiques d’ordre historique, sociologique, anthropologique, philosophique, culturel, artistique et esthétique. En effet, une frontière est une zone composite où se construisent un ensemble de relations vivaces, salvatrices ou violentes entre plusieurs individus, plusieurs peuples, plusieurs États, entre plusieurs cultures et coutumes, mais aussi entre plusieurs paysages, plusieurs textures, plusieurs mouvements et exhalaisons. Ces données constituent des variables qui se font entendre dans le travail des artistes caribéens dont l’œuvre se mesure et se confronte à plusieurs espaces historiques, identitaires, culturels ou institutionnels. Par ailleurs, le sens de ces artistes pour l’hybridation, le mélange et toutes les formes d’imprégnations constitue un fil d’Ariane puissant et constant, qui permet d’affirmer leur advertance pour une culture de la globalité, inscrite dans des espaces parcellaires
My research focuses on the visual artists' work who practice installation art in the French-speaking Caribbean islands. These islands, composed of the French West Indies (Martinique, Guadeloupe, Saint-Martin as well as their administrative dependencies) and the Republic of Haiti, are lands where encounter, miscegenation and Creolity strengthen the permanent relationship that people have with their different genesis, with multiple ramifications and cross-border origins.In this context, installation art, which is located at an infinity of aesthetic explorations’ confluence, through which rules and forms were definitively questioned during the twentieth century, presents itself in the mode of a multidisciplinary approach that, today, is authoritative in many disciplines. Fruit of encounters, impregnations, it is at the thresholds, at the edge of an infinity of geographical, social, political, cultural borders, where the margin that separates the spectator from the work of art dissolves, becomes darkened, fades and faints. This significant boundaries' dissolution between the arts manifests itself in many fields: installation art is a phenomenon revealing this dissolution which, in the French-speaking Caribbean islands, takes on a specific content.In the archipelago, the border question is omnipresent. It mixes historical, sociological, anthropological, philosophical, cultural, artistic and aesthetic issues. Indeed, a boundary is a composite zone where a set of perennial, life-saving or violent relationships is built between several individuals, several peoples, several states, between different cultures and customs, but also between several landscapes, several textures, several movements and exhalations. These data are variables that are heard in the Caribbean artists' work, that measured and confronts several historical, identity, cultural or institutional spaces. Moreover, the sense of these artists for hybridization, mixing and all forms of impregnation constitutes a powerful and constant breadcrumb, which allows to assert their advertence for a culture of globality, inscribed in parcel spaces

In recent times, it has become very important to explicitate the Christian experiences that existed in and co-existed with, or even were immersed in the extrapalestinian cultures, and which were protagonists in the project of the proclamation of the Christian kerygma. Those experiences were lived and realized in the period of Early Christianity and, without a doubt, contributed significantly to its expansion process. We present the passage of Acts 8,26-40, the episode of Philip and the Ethiopia n. What happens here is a dislocation of the missionary-geographical axis from Samaria to the way that goes down from Jerusalem to Gaza , and reaching back to Caesarea. The text opens up the horizon of Christian experiences to other peoples and nations represented in the figure of the Ethiopian eunuch. Taking Acts 8,26-40 in its Lucan redaction as a starting point, using exegetical methods and historical-literary resources, based on the theoretical reference to the concepts of ethnicity and ethnic boundaries, we intend to investigate the possibility of a Christian experience lived in Ethiopia, which constructed itself ethnically from the identities that interacted in the text, and which points out to the imaginary of Ethiopia s symbolic universe. Doing so, we reclaim, within Biblical Exegesis, hermeutical issues for our own theological, biblical, and pastoral practice, on the horizon of the identities and ethnic boundaries of the Africanamerican and Caribian universe.
Torna-se muito importante demonstrar as experiências cristãs que existiram e coexistiram juntas ou/e imersas nas culturas extrapalestinenses e que exerceram protagonismo no anúncio do querigma. São experiências cristãs vividas e realizadas no período do cristianismo primitivo, e que, sem dúvida, contribuíram significativamente para o seu processo de expansão. Apresentamos a perícope Atos 8,26-40. Trata-se do episódio de Filipe e o Etíope. Acontece um deslocamento do eixo geográfico-missionário de Samaria ao caminho que desce de Jerusalém a Gaza , retornando a Cesaréia. O texto abre o horizonte das experiências cristãs a outros povos e nações, representadas nesta perícope pela figura do Etíope eunuco. Partindo de Atos 8,26-40, na perspectiva da redação lucana como ponto de partida, por meio dos procedimentos exegéticos e dos recursos histórico- literários, apoiado no referencial teórico dos conceitos de etnicidade e fronteiras étnicas, nós pretendemos investigar a possibilidade de uma experiência cristã vivenciada na Etiópia, que se constrói etnicamente desde as identidades que interagem na perícope e que apontam ao imaginário do universo simbólico do Etíope. Assim, resgataremos na exegese bíblica pautas hermenêuticas para a nossa prática teológico-bíblica-pastoral no horizonte das identidades e fronteiras étnicas do universo afro americano e caribenho.

Abstract:
This thesis explores aspects of identity, gender and race in the narratives of six white women who wrote about their experiences with Australian Aborigines. Five of the works relate to nineteenth-century frontier encounters, described by middle-class, genteel women who had travelled to distant locations. The sixth (colonial-born) woman wrote about life in outback Queensland in both the late nineteenth century and early twentieth century. Her perceptions and opinions act as a foil to the five other texts, written by British-born authors. My analysis of these works takes into account current colonial racial attitudes and the nineteenth-century utilitarian urge to "educate". It involves discussion of the influences during the nineteenth century of the Enlightenment idea of "man's place in nature", of evangelical Christianity and the role of underlying notions of race based on scientific theories. All these aspects inform the women's works, directly or indirectly. While reflecting ideas about Aborigines expressed in male colonial narratives, these female writers deal with their relationship with Aborigines from a woman's perspective. I have researched the women's social and economic backgrounds in order to investigate biographical factors which lay behind their racial views and perceptions. The thesis explores the influences of publishers requirements and reader expectations on the way Aborigines were represented in published works. The writer’s need to entertain her audience, as well as to "educate" them, often led her to incorporate the traits and language of popular literary trends. Two of these were English Victorian romantic fiction, and the "ripping yarn" adventure narrative, popular from the late nineteenth century. The incorporation of these literary genres often resulted in conflicting messages, and a confused and ambivalent rendition of Aborigines. Within the dynamics of the male power structure at the frontier, these selected female narratives offer another perspective on interracial relations. The six texts refer to the fractious climate of colonisation. They are told by women mostly constrained within the expectations of ladylike decorum and often strongly influenced by the abiding literary contexts of the nineteenth century. What the writings show is that as women grew to know Indigenous people as individuals, representations of Indigenous humanity, agency and authority replace racial cliches and stereotypes, and literary imperatives.

Abstract:
AbstractMigratory pathways across the borders of South Eastern Europe have been commonly recognised within public and policy discourses as the ‘Balkan Route’ (Frontex, 2018; UNHCR, 2019). Yet those pathways do not follow one linear route across the official border checkpoints of former Yugoslav states – Serbia and Bosnia, to the European Union – Croatia and Hungary (Obradovic-Wochnik & Bird, 2019; Stojić & Vilenica, 2019). As often encountered by displaced populations, the journeys consist of perpetually moving onward and being pushed backward across diverse European towns, highways, mountains, forests, rivers, minefields, and camps, necessary to cross to reach western or northern Europe. Displaced people stranded in Serbia and Bosnia generally call their border crossing attempts the ‘game’; the term that conveys the daily mobility struggles, violence and deaths.

Abstract:
Abstract The challenge of drilling in relatively frontier area with active collision margin typical of Eastern Indonesian foreland basins requires an integrated geomechanics analysis to identify drilling hazards, improve well design, and optimize drilling cost. Earlier batch drilling located in the northern part of the Senoro Field targeting on pinnacle carbonates did not encounter significant drilling issue, except for minor tight spots and losses in the carbonate reservoir section. However, later drilling batch in the southern part of the field which associated with large strike-slip faulted platform carbonates encountered significant drilling issues related with pack-off, tight hole, and stuck pipes while tripping in 5000 ft long 12-¼” hole section within the Kintom Formation overburden, despite of initial high penetration rate. In order to identify and prevent similar drilling issues, 1D Wellbore Stability Analysis (WBS) workflow conducted to solve the vertical stress and pore pressure, elastic rock properties, horizontal stresses around the wellbore. Fault stability analysis (FSA) conducted to understand the possibility of fault reactivation due to drilling activity. In addition, lessons-learned from drilling experience and best-practice improvement in offset well is also evaluated to validate with the geomechanics analysis results. Introduction The uniqueness and importance of K-shaped Sulawesi island is long recognized as one of the most tectonically active area in the world where plate collision occurred and has been major interest for research in fields of academic and E&P industry. Recent oil and gas discoveries and multiple potential exploration play in the East Sulawesi area has resulted several prominent mid- to large-sized gas condensate fields, which prompted exploration and development drilling activities since the early 2000’s (Barmi, 2003; Hasanusi, 2004). This trend shows the development of oil and gas field will be increasingly important operation in the area (Fig.1 location map)

Abstract:
Abstract This paper presents a comprehensive laboratory and field study, discussing the development, formulation, and application of a wellbore strengthening mechanism, for strengthening weak formations while drilling in a deepwater high-pressure/high-temperature (HP/HT) well environment. The use of this technology has potential to eliminate nonproductive time (NPT) related to downhole losses, along with extending the drillability of sections and eliminating additional casing strings, during exploratory drilling. During the planning phase of a sequence of deepwater and HP/HT exploration wells, the potential high-pressure case scenario drove the planned and contingency well casing designs. This led to an extensive casing program with a 16-in. sub mudline hanger casing string added to the base design, as well as the normal 36-in. conductor, 20-in. surface casing, 13 ⅜-in. intermediate casing, and 9 ⅝-in. casing, which would enable reaching total depth (TD) within a planned 8 ½-in. hole. The realistic offset well driven by the high-pressure case also required two further contingency liner strings (11 ¾ in. and 7 in.), to be included in the well design. A key enabler for the sequence of wells was that the semisubmersible rig was upgraded to include a managed pressure drilling (MPD) below tension ring (BTR) arrangement. This was enhanced by the MPD well control system and associated risk assessment, allowing working to reduced acceptable kick tolerance limits. In addition to the outlined base and contingency plans, wellbore strengthening was also to be available, as an additional contingency application, to reach TD objectives. Thus, extensive laboratory tests were performed for wellbore strengthening design, using proprietary software, along with past established practices. Subsequent to laboratory testing and the optimal formulation, a detailed wellbore strengthening program was prepared and included in the drilling program, for potential use at any point while drilling ahead. On one well, after cementing of 13 ⅜-in. casing and performing a leakoff test (LOT), it was found that the value was insufficient for drilling through the entire planned section. A contingency 11 ¾-in. liner was being enabled before it was decided to pump the wellbore strengthening pill and strengthen the casing shoe. The pill application gave sufficient increased formation strength, leading to the well section being successfully drilled and cased with no losses, even though the high-pressure well scenario was actually encountered. This solution eliminated the time and cost implication and considerable operational challenges of the 11 ¾-in. contingency liner. This paper presents the study of conceptualizing the wellbore strengthening mechanism and implementing this customized solution in the field. A detailed analysis is also done to identify the optimal products, compatibility with drilling fluid, formation and existing chemical permit, and cost-effectiveness and savings using wellbore strengthening practice. The paper also discusses the comprehensive pit management program and required treatment plan while drilling.

Abstract:
Arctic is the one of the final frontiers in the field of oil and gas exploration. It is also a potential source of the vast amount of renewable energy using wind turbines and wave energy converters. Floating platforms hold certain advantages over fixed platforms for such harsh environment, as they allow disconnection and reconnection in the event of large icebergs or vast multi-year ice floes. They are also commercially attractive as they allow redeployment in other regions during the Arctic off-peak periods. However, such platforms will still need to encounter and withstand first-year level ice of varying sizes and from different directions. Such large ice floes will interfere with the hydrodynamic response of the floater. The hydrodynamic analysis of an isolated floater without accounting for the effect of the level ice is incomplete and may result in a un-conservative prediction of the floater’s response. The lack of any simple methodology to account for the effect of level ice on the hydrodynamic behavior of the floater is the motivation behind this study. This study aims to identify the most relevant parameters affecting the multi-body hydrodynamic behavior of level ice and a single floater. A standard semi-submersible represents the floater, and a range of geometric variations of the level ice simulates the varying nature of the ice environment encountered by the floaters in the Arctic. This study validates the hydrodynamic analysis procedure against model test on an ice floe and wave interaction. The calibration of the model test provides the damping coefficient required for the frequency domain, multi-body hydrodynamic model. This investigation varies the ice orientation and distance from the floater for a detailed parametric study employing the calibrated model. Current research finds that the presence of a comparably sized level ice floe near the floater significantly influences the hydrodynamic Response Amplitude Operator (RAO) of the floater. It can diminish the RAOs in some degree of freedom while enhancing the RAOs in other degree of freedoms. This study identifies the wave direction, ice floe distance, ice floe orientation as the most important parameters. Sway and pitch motion of the floater experienced the most enhancements due to the presence of level ice floe along the incoming wave direction. Additionally, this study proposes some initial upper bound values to account for the effect of level ice floes on the RAOs generated from a single body hydrodynamic analysis.

Abstract:
This paper introduces a novel heat transfer mechanism that facilitates two-phase heat transfer while eliminating the so-called cavitation problem commonly encountered by a conventional pump. The heat transfer device is coined as the reciprocating-mechanism driven heat loop (RMDHL), which includes a hollow loop having an interior flow passage, an amount of working fluid filled within the loop, and a reciprocating driver. The hollow loop has an evaporator section, a condenser section, and a liquid reservoir. The reciprocating driver is integrated with the liquid reservoir and facilitates a reciprocating flow of the working fluid within the loop, so that liquid is supplied from the condenser section to the evaporator section under a substantially saturated condition and the so-called cavitation problem associated with a conventional pump is avoided. The reciprocating driver could be a solenoid-operated reciprocating driver for electronics cooling applications and a bellows-type reciprocating driver for high-temperature applications. Experimental study has been undertaken for a solenoid-operated heat loop in connection with high heat flux thermal management applications. Experimental results show that the heat loop worked very effectively and a heat flux as high as 300 W/cm2 in the evaporator section could be handled. The applications of the bellows-type reciprocating heat loop for gas turbine nozzle guide vanes and the leading edges of hypersonic vehicles are also illustrated. The new heat transfer device is expected to advance the current two-phase heat transfer device and open up a new frontier for further research and development.

Abstract:
Environmental conditions can have major influence on the lifetimes and reliability of active implantable medical devices (e.g., neurostimulators, cochlear implants, internal cardioverter defibrillators). These environmental conditions can range from those encountered by the device in processing and production to transportation and storage to actual operation. Although one might argue that the environmental conditions found in the first two situations are harsher than those of the third, failures that result from those situations are screened before implantation. If we assume that the active medical device is in perfect operational form at the time it is implanted, it will still experience a host of environmental conditions that can affect reliability. In fact, the ultimate goal of these medical devices is to restore the patient, wherever they may reside, to normal activities. A list of some environmental conditions that may be experienced by a device implanted in a representative patient is found in Table 1.

Abstract:
Computer-Aided techniques have been deployed more commonly in recent years to assist with surgical procedures, particularly in the case of minimally invasive surgeries. Arthroscopy, as one of the most prevailing minimally invasive surgical procedures, increases surgical complexity due to the loss of joint visibility, but has many advantages. More obstacles are encountered during hip arthroscopy, given the tight socket-joint hip anatomy. Therefore, computer-aided techniques could be used to ease such difficulties during hip arthroscopy.
