A competência reflexiva processual em servi?o social na a??o profissional junto às popula??es
Granja, Berta;
Cadernos de Pesquisa , 2011, DOI: 10.1590/S0100-15742011000200006
Abstract: this article is the result of ethnographic research that was carried out in portugal, brazil and canada on the professional activities of social assistants. it is centered on aspects relating to the knowledge that is constructed during their interaction with the population. the professional activity of social assistants responds to problems that individuals experience in a singular way; these responses result from the way the social, economic and political structures as well as the systems which influence the lifestyle, life paths and living conditions of individuals, groups and both their individual and collective identities. the answer to these problems in action demands professional knowledge that comes from a specific social and cognitive structure; this knowledge is the basis of the identity form constructed and reconstructed by individual and collective reflection as well as the affirmation of professional autonomy in their actions. the professionals work under constant tension, intrinsic to the action itself, in order to reinvent and adapt procedures that are difficult to codify and formalize when complex social relationships intersect with diverse and at times, antagonistic logics. the tensions, conflicts and limits within the context of the interaction with populations are factors of uncertainty and complexity. to act under these conditions, the professionals need a pattern of regularity and generality that establishes itself as the professional procedures for action, as this article shows.

CENTRAL PARK RUMBA: NUYORICAN IDENTITY AND THE RETURN TO AFRICAN ROOTS
Berta Jottar
Centro Journal , 2011,
Abstract: This essay focuses on the performance of Central Park rumba in the 1960s and 1970s, and its role in the formation of Nuyorican (Puerto Ricans from New York City) identity. Puerto Ricans and Nuyoricans learned and reinterpreted traditional Cuban rumba as their return and performance of African roots. Their search for "roots" resulted in the articulation of a Nuyorican identity reproducing their mediated memory, a rumba knowledge based on mechanical reproduction. What I designate as rumba à la boricua-the result of a mediated, hybrid subjectivity-generated a space of negotiation and contestation against the limitations of nationalism and neo-colonialism.
Single-shot Quantum State Merging
Mario Berta
Physics , 2009,
Abstract: We consider an unknown quantum state shared between two parties, Alice and Bob, and ask how much quantum communication is needed to transfer the full state to Bob. This problem is known as state merging and was introduced in [Horodecki et al., Nature, 436, 673 (2005)]. It has been shown that for free classical communication the minimal number of quantum bits that need to be sent from Alice to Bob is given by the conditional von Neumann entropy. However this result only holds asymptotically (in the sense that Alice and Bob share initially many identical copies of the state) and it was unclear how much quantum communication is necessary to merge a single copy. We show that the minimal amount of quantum communication needed to achieve this single-shot state merging is given by minus the smooth conditional min-entropy of Alice conditioned on the environment. This gives an operational meaning to the smooth conditional min-entropy.
Quantum Side Information: Uncertainty Relations, Extractors, Channel Simulations
Mario Berta
Computer Science , 2013,
Abstract: In the first part of this thesis, we discuss the algebraic approach to classical and quantum physics and develop information theoretic concepts within this setup. In the second part, we discuss the uncertainty principle in quantum mechanics. The principle states that even if we have full classical information about the state of a quantum system, it is impossible to deterministically predict the outcomes of all possible measurements. In comparison, the perspective of a quantum observer allows to have quantum information about the state of a quantum system. This then leads to an interplay between uncertainty and quantum correlations. We provide an information theoretic analysis by discussing entropic uncertainty relations with quantum side information. In the third part, we discuss the concept of randomness extractors. Classical and quantum randomness are an essential resource in information theory, cryptography, and computation. However, most sources of randomness exhibit only weak forms of unpredictability, and the goal of randomness extraction is to convert such weak randomness into (almost) perfect randomness. We discuss various constructions for classical and quantum randomness extractors, and we examine especially the performance of these constructions relative to an observer with quantum side information. In the fourth part, we discuss channel simulations. Shannon's noisy channel theorem can be understood as the use of a noisy channel to simulate a noiseless one. Channel simulations as we want to consider them here are about the reverse problem: simulating noisy channels from noiseless ones. Starting from the purely classical case (the classical reverse Shannon theorem), we develop various kinds of quantum channel simulation results. We achieve this by using classical and quantum randomness extractors that also work with respect to quantum side information.
A Cross-Cultural Perspective on Challenges Facing Comparative Cancer Survivorship Research
Astri Syse,Berta Geller
Journal of Cancer Epidemiology , 2011, DOI: 10.1155/2011/689025
Abstract: Cancer survivorship research includes the study of physical, psychosocial, and economic consequences of cancer diagnosis and treatment among pediatric and adult cancer survivors. Historically, the majority of cancer survivorship studies were from the United States, but survivorship issues are increasingly being addressed in other developed countries. Cross-cultural studies remain, however, scarce. The degree to which knowledge attained may or may not be transferred across cultures, countries, or regions is not known. Some important challenges for comparative research are therefore discussed in a cross-cultural perspective. Several substantive and methodological challenges that complicate the execution of cross-cultural cancer survivorship research are presented with examples and discussed to facilitate comparative research efforts in the establishment of new survivorship cohorts and in the planning and implementation of survivorship studies. Comparative research is one key to understanding the nature of cancer survivorship, distinguishing modifiable from nonmodifiable factors at individual, hospital, societal, and system levels and may thus guide appropriate interventions. Lastly, suggested future courses of action within the field of comparative cancer survivorship research are provided. 1. Introduction The emerging discipline of cancer survivorship research includes the study of the consequences of cancer diagnosis and its treatment among children and adults who have experienced cancer [1]. While the United States (USA) has conducted the majority of research on adult cancer survivorship [2–6], the United Kingdom and Canada have conducted large-scale cohort studies of childhood cancer survivorship [7, 8]. As more countries are beginning to address issues related to adult survivorship [9–20], it will be important to consider how transferrable findings will be across cultures and nations. Identifying generalizable and nongeneralizable research among cultures will hasten what we learn about cancer survivorship. This essay presents an overview of cancer survivorship research and its challenges and discusses in detail three examples of pronounced cross-cultural challenges currently facing the field. Finally, future courses of action within the field of comparative cancer survivorship research are suggested. 2. Cancer Survivorship Research According to the US Institute of Medicine, cancer survivorship research encompasses the physical, psychosocial, and economic consequences of cancer diagnosis and its treatment among both pediatric and adult survivors of
