In the last decades noble metal nanoparticles (NPs) arose as one of the most powerful tools for applications in nanomedicine field and cancer treatment. Glioblastoma multiforme (GBM), in particular, is one of the most aggressive malignant brain tumors that nowadays still presents a dramatic scenario concerning median survival. Gold nanorods (GNRs) and silver nanoparticles (AgNPs) could find applications such as diagnostic imaging, hyperthermia and glioblastoma therapy. During these three years, both GNRs and AgNPs were synthesized with the “salt reduction” method and, through a novel double phase transfer process, using specifically designed thiol-based ligands, lipophilic GNRs and AgNPs were obtained and separately entrapped into biocompatible and biodegradable PEG-based polymeric nanoparticles (PNPs) suitable for drug delivery within the body. Moreover, a synergistic effect of AgNPs with the Alisertib drug, were investigated thanks to the simultaneous entrapment of these two moieties into PNPs. In addition, Chlorotoxin (Cltx), a peptide that specifically recognize brain cancer cells, was conjugated onto the external surface of PNPs. The so-obtained novel nanosystems were evaluated for in vitro and in vivo applications against glioblastoma multiforme. In particular, for GNRs-PNPs, their safety, their suitability as optoacoustic contrast agents, their selective laser-induced cells death and finally, a high tumor retention were all demonstrated. Concerning AgNPs-PNPs, promising tumor toxicity and a strong synergistic effect with Alisertib was observed (IC50 10 nM), as well as good in vivo biodistribution, high tumor uptake and significative tumor reduction in tumor bearing mice. Finally, the two nanostructures were linked together, through an organic framework, exploiting the click chemistry azido-alkyne Huisgen cycloaddition, between two ligands previously attached to the NPs surface; this multifunctional complex nanosystem was successfully entrapped into PNPs with nanoparticles’ properties maintenance, obtaining in this way a powerful and promising tool for cancer fight and defeat.

One of the most serious problems of the modern medicine is the growing emergence of antibiotic resistance among pathogenic bacteria. In this circumstance, different and innovative approaches for treating infections caused by multidrug-resistant bacteria are imperatively required. Bacteriophage Therapy is one among the fascinating approaches to be taken into account. This consists of the use of bacteriophages, viruses that infect bacteria, in order to defeat specific bacterial pathogens. Phage therapy is not an innovative idea, indeed, it was widely used around the world in the 1930s and 1940s, in order to treat various infection diseases, and it is still used in Eastern Europe and the former Soviet Union. Nevertheless, Western scientists mostly lost interest in further use and study of phage therapy and abandoned it after the discovery and the spread of antibiotics. The advancement of scientific knowledge of the last years, together with the encouraging results from recent animal studies using phages to treat bacterial infections, and above all the urgent need for novel and effective antimicrobials, have given a prompt for additional rigorous researches in this field. In particular, in the laboratory of synthetic biology of the department of Life Sciences at the University of Warwick, a novel approach was adopted, starting from the original concept of phage therapy, in order to study a concrete alternative to antibiotics. The innovative idea of the project consists in the development of experimental methodologies, which allow to engineer a programmable synthetic phage system using a combination of directed evolution, automation and microfluidics. The main aim is to make “the therapeutics of tomorrow individualized, specific, and self-regulated” (Jaramillo, 2015). In this context, one of the most important key points is the Bacteriophage Quantification. Therefore, in this research work, a mathematical model describing complex dynamics occurring in biological systems involving continuous growth of bacteriophages, modulated by the performance of the host organisms, was implemented as algorithms into a working software using MATLAB. The developed program is able to predict different unknown concentrations of phages much faster than the classical overnight Plaque Assay. What is more, it gives a meaning and an explanation to the obtained data, making inference about the parameter set of the model, that are representative of the bacteriophage-host interaction.

The aim of this dissertation is to demonstrate how theory and practice are linked in translation. The translation of the essay Light Years Ahead helped me to understand this connection and to develop the two main thesis included in this work, that is the possibility the translator has to choose among all the different theories, without giving one or another the absolute supremacy, and the diversity of the non-fiction genre. Therefore, the first chapter focuses on the different theories of translation, presented in a way which suggests that one might be the completion and the development of another. The second chapter deals with the peculiar issues of non-fiction translation, with particular attention to the way in which this genre gathers different elements of other text types. Despite this variety, it is also claimed that the function at the higher level of an essay is always the informative one. This concept led me to simplify and make more intelligible the Italian version of the text I translated (Light Years Ahead). In the third chapter, this last point is discussed, as well as my considerations about the function, the dominant aspect and the cultural analysis of the text, with particular regard to how the quality of the English translation affected my choices. In the fourth chapter I included some examples of translation, which best demonstrate the distinctive variety of styles of non-fiction texts and the possibility for the translator to choose each time which theory suits them best. Finally, I also included three examples which represent a sort of defeat for me, that is to say three points where the ambiguity of the text obliged me to remove that information for the sake of the dominant informative function.

This article focuses on several key philosophical themes in the criticism of Sakaguchi Ango (1906–1955), one of postwar Japan’s most influential and controversial writers. Associated with the underground Kasutori culture as well as the Burai-ha of Tamura Taijirō (1911–1983), Oda Sakunosuke (1913–1947) and Dazai Osamu (1909–1948), Ango gained fame for two provocative essays on the theme of daraku or “decadence”—Darakuron and Zoku darakuron—pubished in 1946, in the wake of Japan’s traumatic defeat and the beginnings of the Allied Occupation. Less well-known is the fact that Ango spent his student years studying classical Buddhist texts in Sanskrit, Pali and Tibetan, and that he at at one time aspired to the priesthood. The article analyses the concept of daraku in the two essays noted above, particularly as it relates to Ango’s vision of a refashioned morality based on an interpretation of human subjectivity vis-à-vis the themes of illusion and disillusion. It argues that, despite the radical and modernist flavor of Ango’s essays, his “decadence” is best understood in terms of Mahāyāna and Zen Buddhist concepts. Moreover, when the two essays on decadence are read in tandem with Ango’s wartime essay on Japanese culture (Nihon bunka shikan, 1942), they form the foundation for a “postmetaphysical Buddhist critique of culture,” one that is pragmatic, humanistic, and non-reductively physicalist.

With the United States‘ entry into the Second World War, the word ?censorship? was seen largely as antithetical to, rather than a necessary counterpart to, victory among Americans. People did not want to be censored in their writing, photographs or speech,but it proved to be necessary even before the war began, in order to protect government secrets and the people on the home-front from scenes that were too disturbing. Even before the war had officially begun, there were problems with censorship among journalists and newspapers. The initial response of outrage in reference to censorship in the United States was common among journalists, newspapers, magazines, and radio news; nevertheless, there was a necessity for censorship among Americans, on the home frontand the front lines, and it would be tolerated throughout the war to ensure that enemies of America did not gain access to information that would assist in a defeat of the United States in the Second World War. The research I have conducted has dealt with the censorship of combat photography during World War II, in conjunction with the ethics that were in play at the time that affected the censors. Through exploring the work of three combat photographers — Tony Vaccaro, James R. Stephens and Charles E. Sumners — I wasable to effectively construct an explanatory ethical history of these three men. Research on the censorship and effects it had on the United States brought me to three distinctareas of censorship and ethics that would be explored: (1) the restrictions and limitations enforced by the Office of Censorship, (2) a general overview of war and photography as it influenced the soldiers and their families on the home-front, (3) and the combat photographers and personal and military censorship that influenced their work. Although their work was censored both by the military and the government, these men saw the war in a different light that remained with them long after the battles and war had ceased.Using the narratives of Tony Vaccaro, Charles E. Sumners and James R. Stephens as means for more in depth research, this thesis strives to create lenses through which to view the history and ethics of censorship that shaped combat photography during the Second World War and the images to which we refer as representative of that war today.

In my thesis, I incorporate both psychological research and personal narratives in order to explain why, in the aftermath of the Vietnam War, the United States officially recognized Post-Traumatic Stress Disorder while the Vietnamese government did not. The absence of Vietnamese studies on the impact of PTSD on veterans, in comparison to the abundance of research collected on American soldiers, is reflective not of a disparity in the actual prevalence of the disorder, but of the influence of political policy on the scope of Vietnamese psychology. Personal narratives from Vietnamese civilians and soldiers thus reveal accounts of trauma otherwise hidden due to the absence of Vietnamese psychological research. Although these two nations conspicuously differed in their respective responses to the prevalence of psychological trauma in war veterans, these responses demonstrated that both the recognition and rejection of PTSD was a result of sociopolitical factors: political ideologies, rather than scientific reasons, dictated whether the postwar trajectory of psychological research focused on fully exploring the impact of PTSD on veteran populations. The association of military defeat with psychological trauma thus fixed attention on certain groups of veterans, including former American and South Vietnamese soldiers, while ignoring the impact of trauma on veterans of the Viet Cong and North Vietnamese Army. The correlation of a soldier¿s ideological background with psychological trauma, rather than exposure to actual traumatic experiences, demonstrates that cultural and sociopolitical factors are far more influential in the construction of PTSD than objective indicators of the disorder¿s prevalence. Culturally-constructed responses to disorders such as PTSD therefore account for the subjective treatment of mental illness. The American and Vietnamese responses to veterans suffering from PTSD both demonstrated that the evidence of mental health problems in an individual does not guarantee an immediate or appropriate diagnosis and treatment regimen. External authorities whose primary aims are not necessarily concerned with the objective treatment of all victims of mental illness subjectively dictate mental health care policy, and therefore risk ignoring or marginalizing the needs of individuals in need of proper treatment.

Le Siège de Calais, hailed by its author in 1765 as France’s ‘première tragédie nationale’, rolled into Paris like a storm. Pierre-Laurent de Belloy’s play about French bravery during the Hundred Years’ War (1337-1453) appeared on the heels of France’s defeat in the Seven Years’ War (1756-1763). Le Siège de Calais was performed throughout Europe and published numerous times during the second half of the eighteenth century. De Belloy emerged as a national hero, receiving prizes from Louis XV, accolades from the city of Calais, and membership to the prestigious Académie française. Since the French Revolution, however, the popularity of Le Siège de Calais has eclipsed, owing to its overt glorification of France’s royal machine. Several hundred years later, the play warrants a fresh look from a holistic perspective. De Belloy’s tragedy and the varied responses it provoked – many of which are included in this edition – offer complex representations of French political history and patriotic sentiment. Le Siège de Calais reveals conflicting images of gender roles, political debate and family values during the twilight of the Ancien régime; it also constituted one of the last moments when serious drama asserted its role as a popular force.

Social experience influences the outcome of conflicts such that winners are more likely to win again and losers will more likely lose again, even against different opponents. Although winner and loser effects prevail throughout the animal kingdom and crucially influence social structures, the ultimate and proximate causes for their existence remain unknown. We propose here that two hypotheses are particularly important among the potential adaptive explanations: the 'social-cue hypothesis', which assumes that victory and defeat leave traces that affect the decisions of subsequent opponents; and the 'self-assessment hypothesis', which assumes that winners and losers gain information about their own relative fighting ability in the population. We discuss potential methodologies for experimental tests of the adaptive nature of winner and loser effects.

One-hundred years ago, in 1914, male voters in Montana (MT) extended suffrage (voting rights) to women six years before the 19th Amendment to the US Constitution was ratified and provided that right to women in all states. The long struggle for women’s suffrage was energized in the progressive era and Jeanette Rankin of Missoula emerged as a leader of the campaign; in 1912 both major MT political party platforms supported women suffrage. In the 1914 election, 41,000 male voters supported woman suffrage while nearly 38,000 opposed it. MT was not only ahead of the curve on women suffrage, but just two years later in 1916 elected Jeanette Rankin as the first woman ever elected to the United States Congress. Rankin became a national leader for women's equality. In her commitment to equality, she opposed US entry into World War I, partially because she said she could not support men being made to go to war if women were not allowed to serve alongside them. During MT’s initial progressive era, women in MT not only pursued equality for themselves (the MT Legislature passed an equal pay act in 1919), but pursued other social improvements, such as temperance/prohibition. Well-known national women leaders such as Carrie Nation and others found a welcome in MT during the period. Women's role in the trade union movement was evidenced in MT by the creation of the Women's Protective Union in Butte, the first union in America dedicated solely to women workers. But Rankin’s defeat following her vote against World War I was used as a way for opponents to advocate a conservative, traditionalist perspective on women's rights in MT. Just as we then entered a period in MT where the “copper collar” was tightened around MT economically and politically by the Anaconda Company and its allies, we also found a different kind of conservative, traditionalist collar tightened around the necks of MT women. The recognition of women's role during World War II, represented by “Rosie the Riveter,” made it more difficult for that conservative, traditionalist approach to be forever maintained. In addition, women's role in MT agriculture – family farms and ranches -- spoke strongly to the concept of equality, as farm wives were clearly active partners in the agricultural enterprises. But rural MT was, by and large, the bastion of conservative values relative to the position of women in society. As the period of “In the Crucible of Change” began, the 1965 MT Legislature included only three women. In 1967 and 1969 only one woman legislator served. In 1971 the number went up to two, including one of our guests, Dorothy Bradley. It was only after the Constitutional Convention, which featured 19 women delegates, that the barrier was broken. The 1973 Legislature saw 9 women elected. The 1975 and 1977 sessions had 14 women legislators; 15 were elected for the 1979 session. At that time progressive women and men in the Legislature helped implement the equality provisions of the new MT Constitution, ratified the federal Equal Rights Amendment in 1974, and held back national and local conservatives forces which sought in later Legislatures to repeal that ratification. As with the national movement at the time, MT women sought and often succeeded in adopting legal mechanisms that protected women’s equality, while full equality in the external world remained (and remains) a treasured objective. The story of the re-emergence of Montana’s women’s movement in the 1970s is discussed in this chapter by three very successful and prominent women who were directly involved in the effort: Dorothy Bradley, Marilyn Wessel, and Jane Jelinski. Their recollections of the political, sociological and cultural path Montana women pursued in the 1970s and the challenges and opposition they faced provide an insider’s perspective of the battle for equality for women under the Big Sky “In the Crucible of Change.” Dorothy Bradley grew up in Bozeman, Montana; received her Bachelor of Arts Phi Beta Kappa from Colorado College, Colorado Springs, in 1969 with a Distinction in Anthropology; and her Juris Doctor from American University in Washington, D.C., in 1983. In 1970, at the age of 22, following the first Earth Day and running on an environmental platform, Ms. Bradley won a seat in the 1971 Montana House of Representatives where she served as the youngest member and only woman. Bradley established a record of achievement on environmental & progressive legislation for four terms, before giving up the seat to run a strong second to Pat Williams for the Democratic nomination for an open seat in Montana’s Western Congressional District. After becoming an attorney and an expert on water law, she returned to the Legislature for 4 more terms in the mid-to-late 1980s. Serving a total of eight terms, Dorothy was known for her leadership on natural resources, tax reform, economic development, and other difficult issues during which time she gained recognition for her consensus-building approach. Campaigning by riding her horse across the state, Dorothy was the Democratic nominee for Governor in 1992, losing the race by less than a percentage point. In 1993 she briefly taught at a small rural school next to the Northern Cheyenne Indian Reservation. She was then hired as the Director of the Montana University System Water Center, an education and research arm of Montana State University. From 2000 - 2008 she served as the first Gallatin County Court Administrator with the task of collaboratively redesigning the criminal justice system. She currently serves on One Montana’s Board, is a National Advisor for the American Prairie Foundation, and is on NorthWestern Energy’s Board of Directors. Dorothy was recognized with an Honorary Doctorate from her alma mater, Colorado College, was named Business Woman of the Year by the Bozeman Chamber of Commerce and MSU Alumni Association, and was Montana Business and Professional Women’s Montana Woman of Achievement. Marilyn Wessel was born in Iowa, lived and worked in Los Angeles, California, and Washington, D.C. before moving to Bozeman in 1972. She has an undergraduate degree in journalism from Iowa State University, graduate degree in public administration from Montana State University, certification from the Harvard University Institute for Education Management, and served a senior internship with the U.S. Congress, Montana delegation. In Montana Marilyn has served in a number of professional positions, including part-time editor for the Montana Cooperative Extension Service, News Director for KBMN Radio, Special Assistant to the President and Director of Communications at Montana State University, Director of University Relations at Montana State University and Dean and Director of the Museum of the Rockies at MSU. Marilyn retired from MSU as Dean Emeritus in 2003. Her past Board Service includes Montana State Merit System Council, Montana Ambassadors, Vigilante Theater Company, Montana State Commission on Practice, Museum of the Rockies, Helena Branch of the Ninth District Federal Reserve Bank, Burton K. Wheeler Center for Public Policy, Bozeman Chamber of Commerce, and Friends of KUSM Public Television. Marilyn’s past publications and productions include several articles on communications and public administration issues as well as research, script preparation and presentation of several radio documentaries and several public television programs. She is co-author of one book, 4-H An American Idea: A History of 4-H. Marilyn’s other past volunteer activities and organizations include Business and Professional Women, Women's Political Caucus, League of Women Voters, and numerous political campaigns. She is currently engaged professionally in museum-related consulting and part-time teaching at Montana State University as well as serving on the Editorial Board of the Bozeman Daily Chronicle and a member of Pilgrim Congregational Church and Family Promise. Marilyn and her husband Tom, a retired MSU professor, live in Bozeman. She enjoys time with her children and grandchildren, hiking, golf, Italian studies, cooking, gardening and travel. Jane Jelinski is a Wisconsin native, with a BA from Fontbonne College in St. Louis, MO who taught fifth and seventh grades prior to moving to Bozeman in 1973. A stay-at-home mom with a five year old daughter and an infant son, she was promptly recruited by the Gallatin Women’s Political Caucus to conduct a study of Sex-Role Stereotyping in K Through 6 Reading Text Books in the Bozeman School District. Sociologist Dr. Louise Hale designed the study and did the statistical analysis and Jane read all the texts, entered the data and wrote the report. It was widely disseminated across Montana and received attention of the press. Her next venture into community activism was to lead the successful effort to downzone her neighborhood which was under threat of encroaching business development. Today the neighborhood enjoys the protections of a Historic Preservation District. During this time she earned her MPA from Montana State University. Subsequently Jane founded the Gallatin Advocacy Program for Developmentally Disabled Adults in 1978 and served as its Executive Director until her appointment to the Gallatin County Commission in 1984, a controversial appointment which she chronicled in the Fall issue of the Gallatin History Museum Quarterly. Copies of the issue can be ordered through: http://gallatinhistorymuseum.org/the-museum-bookstore/shop/. Jane was re-elected three times as County Commissioner, serving fourteen years. She was active in the Montana Association of Counties (MACO) and was elected its President in 1994. She was also active in the National Association of Counties, serving on numerous policy committees. In 1998 Jane resigned from the County Commission 6 months before the end of her final term to accept the position of Assistant Director of MACO, from where she lobbied for counties, provided training and research for county officials, and published a monthly newsletter. In 2001 she became Director of the MSU Local Government Center where she continued to provide training and research for county and municipal officials across MT. There she initiated the Montana Mayors Academy in partnership with MMIA. She taught State and Local Government, Montana Politics and Public Administration in the MSU Political Science Department before retiring in 2008. Jane has been married to Jack for 46 years, has two grown children and three grandchildren.

The dominant emotion in violence-threatening situations is confrontational tension/fear (ct/f), which causes most violence to abort, or to be carried out inaccurately and incompetently. For violence to be successful, there must be a pathway around the barrier of ct/f. These pathways include: attacking the weak; audience-oriented staged and controlled fair fights; confrontation-avoiding remote violence; confrontation-avoiding by deception; confrontation-avoiding by absorption in technique. Successfully violent persons, on both sides of the law, are those who have developed these skilled interactional techniques. Since successful violence involves dominating the emotional attention space, only a small proportion of persons can belong to the elite which does most of each type of violence. Macro-violence, including victory and defeat in war, and in struggles of paramilitaries and social movements, is shaped by both material resources and social/emotional resources for maintaining violent organizations and forcing their opponents into organizational breakdown. Social and emotional destruction generally precedes physical destruction.

How do sportspeople succeed in a non-collaborative game? An illustration of a perverse side effect of altruism Are team sports specialists predisposed to collaboration? The scientific literature on this topic is divided. The present article attempts to end this debate by applying experimental game theory. We constituted three groups of volunteers (all students aged around 20): 25 team sports specialists; 23 individual sports specialists (gymnasts, track & field athletes and swimmers) and a control group of 24 non-sportspeople. Each subgroup was divided into 3 teams that played against each other in turn (and not against teams from other subgroups). The teams played a game based on the well-known Prisoner's Dilemma (Tucker, 1950) - the paradoxical "Bluegill Sunbass Game" (Binmore, 1999) with three Nash equilibria (two suboptimal equilibria with a pure strategy and an optimal equilibrium with a mixed, egotistical strategy (p= 1/2)). This game also features a Harsanyi equilibrium (based on constant compliance with a moral code and altruism by empathy: "do not unto others that which you would not have them do unto you"). How, then, was the game played? Two teams of 8 competed on a handball court. Each team wore a distinctive jersey. The game lasted 15 minutes and the players were allowed to touch the handball ball with their feet or hands. After each goal, each team had to return to its own half of the court. Players were allowed to score in either goal and thus cooperate with their teammates or not, as they saw fit. A goal against the nominally opposing team (a "guardian" strategy, by analogy with the Bluegill Sunbass Game) earned a point for everyone in the team. For an own goal (a "sneaker" strategy), only the scorer earned a point - hence the paradox. If all the members of a team work together to score a goal, everyone is happy (the Harsanyi solution). However, the situation was not balanced in the Nashian sense: each player had a reason to be disloyal to his/her team at the merest opportunity. But if everyone adopts a "sneaker" strategy, the game becomes a free-for-all and the chances of scoring become much slimmer. In a context in which doubt reigns as to the honesty of team members and "legal betrayals", what type of sportsperson will score the most goals? By analogy with the Bluegill Sunbass Game, we recorded direct motor interactions (passes and shots) based on either a "guardian" tactic (i.e. collaboration within the team) or a "sneaker" tactic (shots and passes against the player's designated team). So, was the group of team sports specialist more collaborative than the other two groups? The answer was no. A statistical analysis (difference from chance in a logistic regression) enabled us to draw three conclusions: ?For the team sports specialists, the Nash equilibrium (1950) was stronger than the Harsanyi equilibrium (1977). ?The sporting principles of equilibrium and exclusivity are not appropriate in the Bluegill Sunbass Game and are quickly abandoned by the team sports specialists. The latter are opportunists who focus solely on winning and do well out of it. ?The most altruistic players are the main losers in the Bluegill Sunbass Game: they keep the game alive but contribute to their own defeat. In our experiment, the most altruistic players tended to be the females and the individual sports specialists

Los mitos de Savitri (Mahabharata 3.293-299) y Orfeo (Ovidio. Metamorfosis 10.1-85), pertenecientes al ámbito cultural indoeur opeo, presentan algunos puntos en común: narran la historia del amante que rescata a su ser amado de la muerte, y combinan el encuentro con los dioses de la muerte y el discurso mediante el poder de la palabra. En esta propuesta, se analizan los discursos de los protagonistas a partir de las convenciones propias de cada contexto de enunciación. Para el caso indio, se sigue el modelo lógico de la escuela Nyaya; para el greco-latino, el de la retórica clásica. De este modo, sobre la base de la estructura argumentativa del silogismo aristotélico, se plantean dos variaciones, respectivamente, el silogismo hindú y el silogismo retórico. Se trata de dos aproximaciones argumentativas con métodos distintos pero con un mismo fin: (con)vencer al oponente

En este trabajo abordamos el análisis de experiencias exiliares de trabajadores chilenos que se radicaron en el Noreste de la Provincia de Chubut, en Patagonia Argentina, después de producido el golpe de estado contra el presidente democrático Salvador Allende Gossens, en Septiembre de 1973. Cuando revisé la factibilidad de la investigación, y en mérito a los escasos repositorios documentales, decidí, dando continuidad a indagaciones previas, trabajar con historia oral. Esta metodología o práctica, involucra una dimensión personal, subjetiva y afectiva, que supone una constante relación entre los sujetos que participan, lo que implica una cualitativa diferencia en relación a las fuentes más tradicionales. No minimizo el valor de la estadística, pero hago una opción por nombrar y conocer a quienes han compartido con nosotros vivencias y experiencias, explicitando nuestra inscripción en la construcción de la información documental, no objetivándonos. El trabajo desarrollado se halla en la encrucijada entre la historia del pasado reciente y la memoria; con una perspectiva "desde abajo", buscando conjugar la no uniformidad de la experiencia humana, con la pretensión de generalidad y explicación de la ciencia social. Las narraciones o testimonios obtenidos las he revisado, procurando develar las representaciones que subyacen, y comprendiendo el modo en que actuaron. Las memorias tienen un carácter subjetivo y en permanente transformación, lo que en cierto sentido puede singularizarlas, pero como historiadores debemos inscribirlas en un contexto histórico global, para procurar esclarecer las causas, las condiciones, y las estructuras, aportando a una historia total. Hemos rescatado prácticas, percepciones, y discursos; develando la importancia del trabajo como factor organizador y estabilizador, al dotar a estos sujetos, de un sitio en la sociedad receptora, y permitiéndoles "ir desarmando sus valijas", es decir, ir superando la transitoriedad. Al caracterizar al exilio chileno, en el contexto internacional y local; y atendiendo a las escasas producciones que dan cuenta del universo obrero en estas experiencias traumáticas, han sido evidentes los límites que supone una estricta separación entre exilio, y migración económica o política; ya que dicha conceptualización encierra una mirada que invisibiliza derroteros que en principio, o superficialmente, pueden ser leídos como poco organizados. La aplicación del análisis de red, por cierto contribuyó a hacerlos visibles, transformándolos en actores racionales, con objetivos que se movilizaron a partir de los recursos de que dispusieron; tratando de superar el paradigma que hacía de ellos seres desesperados: fueron mujeres y hombres que eligieron un destino posible, siempre atendiendo al doble carácter de la experiencia en que estuvieron inmersos: la salida de su país por un lado los liberó, pero también los privó; asociando indisolublemente sentimientos de dolor por el desprendimiento de lo propio -de los afectos personales y colectivos-, agravados por los efectos de la derrota y la incertidumbre. Son sujetos que pusieron su identidad en riesgo. Pretendemos lograr que esta investigación, no sea sólo un estudio de caso, sino que pueda inscribirse a partir de su especificidad, en tanto exilio obrero, en una perspectiva comparativa, superando una definición espacial específica, en el Nor Este de Chubut.
