O derramamento do Espírito : fortalecimento dos enfraquecidos

Esta tese se insere dentro da leitura bíblica latino-americana trazendo, nessa ótica, a riqueza e o desafio do que significa ler a Bíblia a partir de um contexto de opressão como é o nosso continente. Nos servimos do roteiro das ciências bíblicas e dos métodos exegéticos modernos. É uma pesquisa bibliográfica onde, eventualmente, consideramos o nível experiêncial, por exemplo quando trabalhamos o tema do derramamento do Espírito nos pentecostais chilenos. Esse capítulo, IV, segue o roteiro da hipótese central de nossa tese na medida que firmamos o princípio de que os pentecostais fazem parte do amplo e diverso grupo dos enfraquecidos como produto de um sistema excludente, baseado na exploração social. Numa situação de crise, o anúncio do derramamento do Espírito é um sinal de salvação, de perspectivas futuras, de conservação e prolongação da vida. Esta tese relê o tema do derramamento do Espírito, a partir de Jl 3,1-5. O tema é analisado num contexto social concreto, onde os enfraquecidos recebem o Espírito do Senhor. O eixo que nos permite fazer esta leitura encontra sua referencial nas pessoas setores sociais - mencionadas como beneficiadas diretas da ação do Espírito. São pessoas que representam setores diferentes; jovens, escravos e escravas, formam o grupo que sustenta e faz funcionar o sistema imperial persa grego - baseado na exploração e mão de obra barata. Eles, juntamente com os idosos que não produzem mais, são a base de sustentação da pirâmide social. Como demostraremos no decorrer da tese, nossa hipótese somente é possível se duas conjunturas se cruzam. Para isso, em num primeiro momento, localizamos e demostramos que o livro de Joel deve ser situado no contexto da literatura apocalíptica (nascimento). Em seguida, demonstramos que o livro de Joel, como produto literário final, deve ser localizado no contexto histórico do pós-exílio, isto é, no tempo dos impérios persa e grego. A confirmação destes dois aspectos desenvolvidos nos capítulos I e II, nos permitem, na análise literária, capítulo III, aprofundar, mediante a análise exegética, e confirmar a nossa hipótese central. Com estes três capítulos demostramos que o derramamento do Espírito do Senhor tem como destinatários preferenciais, senão exclusivos, os setores enfraquecidos pela política social, econômica e religiosa dos impérios persa e grego. Com estes três capítulos desenvolvidos, no quarto capítulo analisamos uma experiência concreta, de um setor majoritariamente pobre que tem se apropriado do texto de Jl 3,1-5, e encontrado nele uma alternativa social, política e religiosa para se manter fiel ao Senhor e por quase um século recria e revive a experiência do derramamento do Espírito. Os velhos, os jovens, os escravos e as escravas, formam o setor dos enfraquecidos. É o setor que nada espera, e que nada terá da parte dos impérios e que, como os pentecostais, pela sua situação de enfraquecimento, acredita que somente uma intervenção externa pode mudar o seu futuro, pode trazer de volta a esperança. Essa intervenção externa começa a ser possível pelo derramamento do Espírito e se concretiza na chegada do dia de Javé, que será grande e terrível, onde o sol e a lua se unem para indicar o monte de Sião e a cidade de Jerusalém como lugar de adoração, refúgio e salvação. Esta perspectiva da ação do Espírito é possível somente no período do pós-exílio. Nesse tempo o Espírito adquire uma dimensão ampla e inclusiva agindo sobre diversos setores sociais, independe de serem ou não judeus.(AU)

A VIOLÊNCIA CONTRA AS MULHERES NA VIDA COTIDIANA Um estudo do Livro da Aliança a partir de Êxodo 20,22-23,19

O espaço social subjacente à unidade literária de Êxodo 20,22-23,19 pressupõe uma sociedade agrária. Aparentemente é monótona, marcada por inúmeros conflitos sociais. O contexto social é de empobrecimento das famílias clânico-tribais israelitas. A nova economia se organiza em torno do santuário. Na pesquisa, há bastante consenso quanto à origem desta unidade literária conhecida como Livro da Aliança. É literatura jurídica de caráter religioso. Uma prescrição jurídica não precede as condições da realidade a que vai se referir, mas prescreve sobre as condições e situações já existentes. Na pesquisa clássica atual, encontram-se duas grandes correntes sobre a origem e a época desta literatura. Uma defende que o Livro da Aliança remonta à época pré-estatal, passagem do tribalismo para a monarquia; a outra argumenta que o Livro da Aliança, enquanto corpus codificado de leis, é um produto tardio , possivelmente surgido no final do século VIII ou início do século VII a.C. O Livro da Aliança é a base literária da presente pesquisa. Quanto à origem e à época do Livro da Aliança, sigo a corrente que defende ser o texto da época final do período tribal, anterior à monarquia. Esta época foi marcada por grandes mudanças econômicas: passagem de uma economia solidária de subsistência para uma economia de concentração do produto. A tese consiste em analisar a violência contra as mulheres, estruturada no discurso jurídico do Livro da Aliança. Busca-se desvendar os mecanismos que justificam e naturalizam as práticas de violência. O destaque é a violência contra as mulheres escravas, contra as filhas e, de modo especial, enfatizo as violências contra as mulheres feiticeiras. Evidencio três categorias de escravas prescritas no texto: as escravas domésticas, que sofrem violências físicas, podendo chegar até à morte debaixo do castigo da vara; as escravas temporárias, que têm seus olhos destruídos e os seus dentes quebrados; e as filhas que são vendidas como escravas. Sua sexualidade é transformada em mercadoria. Há filhas que são seduzidas, violadas e submetidas como mulher ao seu estuprador. O único grupo social descrito a partir da sua função pública são as feiticeiras. As violências são institucionais e sexistas. O patriarcado é o princípio organizador da sociedade. A característica do Livro da Aliança é marcadamente androcêntrica.(AU)

CRIAÇÃO E RECRIAÇÕES COSMOGÔNICAS EM ISAÍAS 51, 9-11: Um estudo do uso do mito cosmogônico pelo Dêutero-Isaías para o entendimento da comunidade dos cativos judaítas em Babilônia

Como estudar uma cultura ou uma comunidade perdida nos tempos bíblicos? Esta é um questão motriz para o autor. Foi dessa maneira que surgiu o seu interesse em discutir a possibilidade do uso do mito cosmogônico para o entendimento da comunidade dos cativos judaítas em Babilônia. É uma iniciativa, que precisava ser trilhada pelos pesquisadores que se dispusessem ao estudo das culturas do mundo bíblico. Assim se elegeu o tema Mito Cosmogônico no Primeiro Testamento como instrumento de aprofundamento da pesquisa bíblica. O mito é uma escolha mais ou menos óbvia, pela sua capacidade de funcionar como paradigma, pragmática e traditiva contra-hegemônica dentro de um contexto social interétnico. Estas eram ponderações vindas de matrizes como a do fenomenólogo Mircea Eliade, do Antropólogo Roger Bastide e do teólogo e fenomenólogo José Severino Croatto. É por isto que um paralelo é traçado entre o mito de Marduk e o texto de Isaías 51, 9-11, que fala de Javé como sendo criador do mundo e que luta contra as forças do caos. Isto é feito, com vistas à percepção da profecia do Isaías do exílio, como parentesco e sua justaposição com a mitologia babilônica, e ambos se aproximam bastante de forma sintagmática e histórico-social. Coube ainda saber se a profecia do Dêutero-Isaías atuava da mesma maneira que o poema Enuma elish funcionava para os babilônicos. Ou seja, fazia-se surgir modelos sociais às comunidades de escravos dentro do Império Neobabilônico; se com base nestes cânticos, os cativos conseguiam construir um ordenamento para as suas comunidades, que gozavam de uma relativa autonomia, tais como colônias e guetos ; se de posse dessa ousada profecia, os judeus da golah eram capazes de elaborar uma desobediência cívil nos termos de um nutrir nos corações, uma utopia que rompesse com o status quo do passado, comprometendo-os com a esperança no Javé criador.(AU)

Sugar and coffee: A history of settler agriculture in nineteenth-century Liberia

This dissertation is about commercial agriculture in nineteenth-century Liberia. Based primarily on the archives of the American Colonization Society (founder of Liberia), it examines the impact of environmental and demographic constraints on an agrarian settler society from 1822 to the 1890s. Contrary to the standard interpretation, which linked the poor state of commercial agriculture to the settlers' disdain for cultivation, this dissertation argues that the scarcity of labor and capital impeded the growth of commercial agriculture. The causes of the scarcity were high mortality, low immigration and the poverty of the American “Negroes” who began to settle Liberia in 1822. ^ Emigration to Liberia meant almost certain death and affliction for many immigrants because they encountered a new set of diseases. Mortality was particularly high during the early decades of colonization. From 1822 to 1843, about 48 percent of all immigrants died of various causes, usually within their first year. The bulk of the deaths is attributed to malaria. There was no natural increase in the population for this early period and because American “Negroes” were unenthusiastic about relocation to Liberia, immigration remained sparse throughout the century. Low immigration, combined with the high death rate, deprived the fledgling colony of its potential human resource, especially for the cultivation of labor-intensive crops, like sugar cane and coffee. Moreover, even though females constituted approximately half of the settlers, they seldom performed agricultural labor. ^ The problem of labor was compounded by the scarcity of draft animals. Liberia is in the region where trypanosomiasis occurs. The disease is fatal to large livestock. Therefore, animal-drawn plows, common in the United States, were never successfully transplanted in Liberia. Besides, the dearth of livestock obstructed the development of the sugar industry since many planters depended on oxen-powered mills because they could not afford to buy the more expensive steam engine mills. ^ Finally, nearly half of the immigrants were newly emancipated slaves. Usually these former bondsmen arrived in Liberia penniless. Consequently, they lacked the capital to invest in large-scale plantations. The other categories of immigrants (e.g., those who purchased their freedom), were hardly better off than the emancipated slaves. ^

Autonomy and authority in the lives of children who work as domestic servants in Ghana

Limited literature exists on Ghana's child domestic servants, and researchers have found it difficult to locate and study these children. The research for this dissertation used qualitative research methodologies and non-probabilistic sampling techniques to make it possible to interview child domestic servants, their parents, employers and recruiters in Ghana. The findings from the qualitative analyses informed the second part of this study, which was quantitative and tested hypotheses using crosstabulations and logistic regression analyses that were based on survey data from the Ghana Statistical Service. Explanatory variables in the quantitative analyses included lineage, level of education and relationships to the household head. ^ This study located findings about the processes of children's recruitment into domestic servitude, their working conditions and methods of remuneration in theories of slavery to answer the question of whether or not child domestic servants are slaves. According to the findings, elite households in Ghana exploit children from rural regions because they have taken advantage of a historical practice that allowed children to live with older members of their extended families to provide domestic services and in return, be given the chance to receive formal education or to learn a trade. The participants in the qualitative part of this research described the treatments that they receive from their employers as slavery. Nevertheless, the processes of their recruitment and the age at which most of them accepted such job offers made it difficult to categorize a majority of them as contemporary slaves. ^

"And a child shall lead them?": Slavery, childhood, and African cultural identity in Jamaica, 1750--1838

Based primarily on archival evidence collected in Jamaica, this dissertation examined the nature of childhood in the plantation complex between 1750 and 1838, how colonial society and the slave community defined childhood, and how that definition changed over time. It proves how childhood and slavery influenced and changed each other during these years, with the abolitionist movement standing as the main catalyst for change. Although this project chronologically examined the changing nature of slave childhood in Jamaica through four shifts of Jamaican history, each chapter topically focused on slave childhood through the lenses of labor, family, resistance, race, status, culture, education, and freedom. ^ The research showed that although slavery forced slave children into an early adulthood, childhood was a contested process that changed with each generation of children. As the abolitionist movement motivated changes in planter opinion on the value of children to the plantation economy, planters placed increased responsibility on slave children to lead them towards economic stability and profitability. Meanwhile, slave children struggled to survive slavery by reinventing and modifying their ideas of family and kinship and reacting to their situation through various acts of resistance. Although slave parents gained many opportunities to raise their children on their own terms, they struggled to maintain control over that process as planters attempted to change the nature of African cultural identity in Jamaica by impressing Christian and English values on slave children. Under apprenticeship, childhood returned to its previous status as a liability in the eyes of the Jamaican planters. Yet, Jamaican children faced the prospect of an unwritten childhood, one that was free from planter control and gave Jamaican laborers hope for the future. In the end, this dissertation told the story of an overlooked childhood, one that was often defined by Jamaican planters, but frequently contested by the slaves themselves. ^

Adaptive fault-tolerant teleoperation

While the robots gradually become a part of our daily lives, they already play vital roles in many critical operations. Some of these critical tasks include surgeries, battlefield operations, and tasks that take place in hazardous environments or distant locations such as space missions. ^ In most of these tasks, remotely controlled robots are used instead of autonomous robots. This special area of robotics is called teleoperation. Teleoperation systems must be reliable when used in critical tasks; hence, all of the subsystems must be dependable even under a subsystem or communication line failure. ^ These systems are categorized as unilateral or bilateral teleoperation. A special type of bilateral teleoperation is described as force-reflecting teleoperation, which is further investigated as limited- and unlimited-workspace teleoperation. ^ Teleoperation systems configured in this study are tested both in numerical simulations and experiments. A new method, Virtual Rapid Robot Prototyping, is introduced to create system models rapidly and accurately. This method is then extended to configure experimental setups with actual master systems working with system models of the slave robots accompanied with virtual reality screens as well as the actual slaves. Fault-tolerant design and modeling of the master and slave systems are also addressed at different levels to prevent subsystem failure. ^ Teleoperation controllers are designed to compensate for instabilities due to communication time delays. Modifications to the existing controllers are proposed to configure a controller that is reliable in communication line failures. Position/force controllers are also introduced for master and/or slave robots. Later, controller architecture changes are discussed in order to make these controllers dependable even in systems experiencing communication problems. ^ The customary and proposed controllers for teleoperation systems are tested in numerical simulations on single- and multi-DOF teleoperation systems. Experimental studies are then conducted on seven different systems that included limited- and unlimited-workspace teleoperation to verify and improve simulation studies. ^ Experiments of the proposed controllers were successful relative to the customary controllers. Overall, by employing the fault-tolerance features and the proposed controllers, a more reliable teleoperation system is possible to design and configure which allows these systems to be used in a wider range of critical missions. ^

Rich and poor, white and black, free and slave: The social history of Cuba's tobacco farmers, 1763--1817

Tobacco was of primary importance to Spain, and its impact on Cuba's economy and society was greater than just the numbers of farms, workers, or production, demonstrated by the Spanish crown's outlay of monies for capital assets, bureaucrats' salaries, and payments to farmers for their crop. This study is a micro- and macro-level study of rural life in colonial Cuba and the interconnected relationships among society, agricultural production, state control, and the island's economic development. ^ By placing Cuba's tobacco farmers at the forefront of this social history, this work revisits and offers alternatives to two prevailing historiographical views of rural Cuba from 1763 (the year Havana returned to Spanish control following the Seven Years' War) to 1817 (the final year of the 100-year royal monopoly on Cuban tobacco). Firstly, it argues against the primacy of sugar over other agricultural crops, a view that has shaped decades of scholarship, and challenges the thesis which maintains the Cuban tobacco farmer was almost exclusively poor, white, and employed free labor, rather than slaves, in the production of their crop. ^ This study establishes the importance of tobacco as an agricultural product, and argues that Cuban tobacco growers were a heterogeneous group, revealing the role that its cultivation may have played in helping some slaves earn their freedom. ^

New fuel cells system for portable application with low temperature cofired ceramic (LTCC) technology

Miniature direct methanol fuel cells (DMFCs) are promising micro power sources for portable appliction. Low temperature cofired ceramic (LTCC), a competitive technology for current MEMS based fabrication, provides cost-effective mass manufacturing route for miniature DMFCs. Porous silver tape is adapted as electrodes to replace the traditional porous carbon electrodes due to its compatibility to LTCC processing and other electrochemical advantages. Electrochemical evaluation of silver under DMFCs operating conditions demonstrated that silver is a good electrode for DMFCs because of its reasonable corrosion resistance, low passivating current, and enhanced catalytic effect. Two catalyst loading methods (cofiring and postfiring) of the platinum and ruthenium catalysts are evaluated for LTCC based processing. The electrochemical analysis exhibits that the cofired path out-performs the postfiring path both at the anode and cathode. The reason is the formation of high surface area precipitated whiskers. Self-constraint sintering is utilized to overcome the difficulties of the large difference of coefficient of thermal expansion (CTE) between silver and LTCC (Dupont 951) tape during cofiring. The graphite sheet employed as a cavity fugitive insert guarantees cavity dimension conservation. Finally, performance of the membrane electrode assembly (MEA) with the porous silver electrode in the regular graphite electrode based cell and the integrated cofired cell is measured under passive fuel feeding condition. The MEA of the regular cell performs better as the electrode porosity and temperature increased. The power density of 10 mWcm-2 was obtained at ambient conditions with 1M methanol and it increased to 16 mWcm -2 at 50°C from an open circuit voltage of 0.58V. For the integrated prototype cell, the best performance, which depends on the balance methanol crossover and mass transfer at different temperatures and methanol concentrations, reaches 1.13 mWcm-2 at 2M methanol solution at ambient pressure. The porous media pore structure increases the methanol crossover resistance. As temperature increased to 60°C, the device increases to 2.14 mWcm-2.

Representation of people of color in the nineteenth century slavery novel in Cuba and Brazil

This dissertation explores the similarities and differences which characterize the depiction of people of color in certain representative nineteenth century Cuban and Brazilian slavery novels as a function of the authorial approach of each territory's literary tradition toward the issues of slavery, racial prejudice, and people of color. The selected texts, derived from the peak periods in slavery literature of each territory, include Francisco , by Anselmo Snárez y Romero; Sab, by Gertrudis Gómez de Avellaneda; Cecilia Valdés , by Cirilo Villaverde; A escrava Isaura, by Bernardo Guimarães; O mulato, by Aluísio Azevedo; and Bom-Crioulo, by Adolfo Caminha. While the present study explores the enslavement, abuse, and discrimination of people of color as a consequence of a deep-seated discourse of power, privilege and racial superiority, it focuses more extensively on the representation of people of color, particularly in their capacity to constructively appropriate the cultural values of the white dominant group and recognize their identity as ambiguous. ^ Said's theories of Orientalist discourse and geography and formation as well as Dube's perspective on subaltern-oriented studies provide a theoretical framework for exploring the response of slavery writers whose common exposure to slavery but dissimilar socio-political contexts generate some startling findings. Crafted within a period of political repression, fear of black revolt, factional in-fighting as well as strong socioeconomic ties to the slaveholding class, the Cuban texts generally fashioned an approach to slavery as one marked by moderation, reform, and cultural counter discourse and consequently depict people of color with a more passive but culturally authentic outlook. On the other hand, the Brazilian response to the issue of slavery, steeped in an ideological amalgam of liberalism, positivism, republicanism, and abolitionism, is characterized by overt opposition to slavery and a representation of people of color that is less concerned with cross-cultural input but reclaims their humanity as highly educable and socially mobile persons in search of greater freedoms. Ultimately, there is a shared message of higher significance couched in the worthwhile mission of raising slaves to the level of men. ^

Inter-subjective and transnational racial effects: The role of the United States in the formation and evolution of the collective perception and racial relations in Cuba, 1898–1902

Since the arrival of the first African slaves to Cuba in 1524, the issue of race has had a long-lived presence in the Cuban national discourse. However, despite Cuba’s colonial history, it has often been maintained by some historians that race relations in Cuba were congenial with racism and racial discrimination never existing as deep or widespread in Cuba as in the United States (Cannon, 1983, p. 113). In fact, it has been argued that institutionalized racism was introduced into Cuban society with the first U.S. occupation, during 1898–1902 (Cannon, 1983, p. 113). This study of Cuba investigates the influence of the United States on the development of race relations and racial perceptions in post-independent Cuba, specifically from 1898-1902. These years comprise the time period immediately following the final fight for Cuban Independence, culminating with the Cuban-Spanish-American War and the first U.S. occupation of Cuba. By this time, the Cuban population comprised Africans as well as descendants of Africans, White Spanish people, indigenous Cubans, and offspring of the intermixing of the groups. This research studies whether the United States’ own race relations and racial perceptions influenced the initial conflicting race relations and racial perceptions in early and post-U.S. occupation Cuba. This study uses a collective interpretative framework that incorporates a national level of analysis with a race relations and racial perceptions focus. This framework reaches beyond the traditionally utilized perspectives when interpreting the impact of the United States during and following its intervention in Cuba. Attention is given to the role of the existing social, political climate within the United States as a driving influence of the United States’ involvement with Cuba. This study reveals that emphasis on the role of the United States as critical to the development of Cuba’s race relations and racial perceptions is credible given the extensive involvement of the U.S. in the building of the early Cuban Republic and U.S. structures serving as models for reconstruction. U.S. government formation in Cuba aligned with a governing system reflecting the existing governing codes of the U.S. during that time period.

The peopling of the Bahamas: A phylogeographical perspective

During the past 500 years, the Bahamas has been influenced by a wide array of settlers, including but not limited to, the Arawak Indians, Eleutherian Adventurers, British Loyalists, Creole slaves, liberated Africans as well as Chinese, Greek, Jewish, Lebanese, Jamaican and Haitian migrants. To date, however, only a few reports analyzing the genetic makeup and population dynamics of the Bahamas have been published, making this work pivotal in the endeavor to ascertain the genetic ancestry of these groups. As such, the current investigation was undertaken to genetically characterize six of the more densely populated islands throughout the Northwest (Grand Bahama and Abaco) and Central (Eleuthera, Exuma, Long Island and New Providence) Bahamas using different forensic marker systems. When autosomal STR markers are employed, the Bahamian collections were all found to receive differential contributions from the African, European, East Asian and Native American collections utilized in the analyses. Similar findings were also observed for two other Afro-Caribbean populations, Haiti and Jamaica, although the latter populace was found to share a greater proportion of its autosomal component with non-African sources than the former. On the contrary, analysis of the six Bahamian collections using high-resolution Y-chromosome markers identifies genetic signals emanating exclusively from Africans and Europeans, but this is likely the result of smaller sample sizes collected from each island and/or sex-biased gene flow from East Asian and Native American groups.

Negotiating identities, striving for state recognition: Blacks in Córdoba, Argentina 1776–1853

Race in Argentina played a significant role as a highly durable construct by identifying and advancing subjects (1776–1810) and citizens (1811–1853). My dissertation explores the intricacies of power relations by focusing on the ways in which race informed the legal process during the transition from a colonial to national State. It argues that the State’s development in both the colonial and national periods depended upon defining and classifying African descendants. In response, people of African descendent used the State’s assigned definitions and classifications to advance their legal identities. It employs race and culture as operative concepts, and law as a representation of the sometimes, tense relationship between social practices and the State’s concern for social peace. This dissertation examines the dynamic nature of the court. It utilizes the theoretical concepts multicentric legal orders that are analyzed through weak and strong legal pluralisms, and jurisdictional politics, from the late eighteenth to early nineteenth centuries. This dissertation juxtaposes various levels of jurisdiction (canon/state law and colonial/national law) to illuminate how people of color used the legal system to ameliorate their social condition. In each chapter the primary source materials are state generated documents which include criminal, ecclesiastical, civil, and marriage dissent court cases along with notarial and census records. Though it would appear that these documents would provide a superficial understanding of people of color, my analysis provides both a top-down and bottom-up approach that reflects a continuous negotiation for African descendants’ goal for State recognition. These approaches allow for implicit or explicit negotiation of a legal identity that transformed slaves and free African descendants into active agents of their own destinies.

The Chef In Society: Origins And Development

In his discourse - The Chef In Society: Origins And Development - Marcel R. Escoffier, Graduate Student, School of Hospitality Management at Florida International University, initially offers: “The role of the modern professional chef has its origins in ancient Greece. The author traces that history and looks at the evolution of the executive chef as a manager and administrator.” “Chefs, as tradespersons, can trace their origins to ancient Greece,” the author offers with citation. “Most were slaves…” he also informs you. Even at that low estate in life, the chef was master of the slaves and servants who were at close hand in the environment in which they worked. “In Athens, a cook was the master of all the household slaves…” says Escoffier. As Athenian influence wanes and Roman civilization picks-up the torch, chefs maintain and increase their status as important tradesmen in society. “Here the first professional societies of cooks were formed, almost a hierarchy,” Escoffier again cites the information. “It was in Rome that cooks established their first academy: Colleqium Coquorum,” he further reports. Chefs, again, increase their significance during the following Italian Renaissance as the scope of their influence widens. “…it is an historical fact that the marriage of Henry IV and Catherine de Medici introduced France to the culinary wonders of the Italian Renaissance,” Escoffier enlightens you. “Certainly the professional chef in France became more sophisticated and more highly regarded by society after the introduction of the Italian cooking concepts.” The author wants you to know that by this time cookbooks are already making important inroads and contributing to the history of cooking above and beyond their obvious informational status. Outside of the apparent European influences in cooking, Escoffier also ephemerally mentions the development of Chinese and Indian chefs. “It is interesting to note that the Chinese, held by at least one theory as the progenitors of most of the culinary heritage, never developed a high esteem for the position of chef,” Escoffier maintains the historical tack. “It was not until the middle 18th Century that the first professional chef went public. Until that time, only the great houses of the nobility could afford to maintain a chef,” Escoffier notes. This private-to-public transition, in conjunction with culinary writing are benchmarks for the profession. Chefs now establish authority and eminence. The remainder of the article devotes itself to the development of the professional chef; especially the melding of two seminal figures in the culinary arts, Cesar Ritz and August Escoffier. The works of Frederick Taylor are also highlighted.

Adaptive Fault-Tolerant Teleoperation

While the robots gradually become a part of our daily lives, they already play vital roles in many critical operations. Some of these critical tasks include surgeries, battlefield operations, and tasks that take place in hazardous environments or distant locations such as space missions. In most of these tasks, remotely controlled robots are used instead of autonomous robots. This special area of robotics is called teleoperation. Teleoperation systems must be reliable when used in critical tasks; hence, all of the subsystems must be dependable even under a subsystem or communication line failure. These systems are categorized as unilateral or bilateral teleoperation. A special type of bilateral teleoperation is described as force-reflecting teleoperation, which is further investigated as limited- and unlimited-workspace teleoperation. Teleoperation systems configured in this study are tested both in numerical simulations and experiments. A new method, Virtual Rapid Robot Prototyping, is introduced to create system models rapidly and accurately. This method is then extended to configure experimental setups with actual master systems working with system models of the slave robots accompanied with virtual reality screens as well as the actual slaves. Fault-tolerant design and modeling of the master and slave systems are also addressed at different levels to prevent subsystem failure. Teleoperation controllers are designed to compensate for instabilities due to communication time delays. Modifications to the existing controllers are proposed to configure a controller that is reliable in communication line failures. Position/force controllers are also introduced for master and/or slave robots. Later, controller architecture changes are discussed in order to make these controllers dependable even in systems experiencing communication problems. The customary and proposed controllers for teleoperation systems are tested in numerical simulations on single- and multi-DOF teleoperation systems. Experimental studies are then conducted on seven different systems that included limited- and unlimited-workspace teleoperation to verify and improve simulation studies. Experiments of the proposed controllers were successful relative to the customary controllers. Overall, by employing the fault-tolerance features and the proposed controllers, a more reliable teleoperation system is possible to design and configure which allows these systems to be used in a wider range of critical missions.
