Como podem as organizações gerir paradoxos?

As organizações participam em ambientes que, além de complexos, são repletos de ambiguidade e de exigências contraditórias. A capacidade de trabalhar com os paradoxos é necessária para responder a essa complexidade ambiental. Este artigo discute como esse desafio pode ser levado a cabo. Começa por esclarecer a diferença entre processos por vezes equiparados a paradoxos por envolverem contradições, nomeadamente dilemas e dialéticas. Trata, depois, de diferentes possibilidades de resposta às situações paradoxais. Discute, finalmente, como dessas respostas podem resultar círculos viciosos versus virtuosos.

Entre riscos e rabiscos: da leitura à representação (gráfica) de provérbios

De tradição oral e de origem remota, os provérbios circunscrevem a realidade cultural dos seus criadores e utilizadores. A sua riqueza reside, por um lado, na mensagem sintética e por isso, também, pragmática, ao ser utilizada como âncora em contextos específicos; reside, por outro lado, na construção de metáforas conceptuais, tradutoras de verdades e generalizações sedimentadas na observação empírica. É nestas que a língua portuguesa (LP) germina a dimensão cultural e permite a exploração de mundividências partilhadas, transparentes, translúcidas ou opacas. O trabalho que propomos apresentar descreve um conjunto de atividades realizadas com alunos do 5.o ao 8.o ano de escolaridade, no âmbito de um programa desenvolvido por um agrupamento de escolas da região de Viseu e uma instituição de ensino superior durante o ano letivo de 2013-2014. As atividades que propusemos implicaram considerar a LP a partir de diferentes prismas, perspetivando-a não só como código verbal, como herança cultural, mas também como espaço de criação e criatividade. Assim, a sedimentação de significados que foram construindo a LP é apresentada aos alunos como enigma a desvelar. Neste sentido, propomos a) analisar a representação gráfica de provérbios feita por alunos do ensino básico; b) refletir sobre a influência da LP na formação de provérbios em países de expressão portuguesa. A sua interpretação é padronizada, mas permeável a ambiguidades. Neste caso, e a partir da comparação de um exercício de equivalência entre provérbios representados pela variedade do português, revelamos a seleção dos alunos.

Cognitive and Visual Speech Contributions to Speech Perception in Challenging Listening Conditions

Speech perception routinely takes place in noisy or degraded listening environments, leading to ambiguity in the identity of the speech token. Here, I present one review paper and two experimental papers that highlight cognitive and visual speech contributions to the listening process, particularly in challenging listening environments. First, I survey the literature linking audiometric age-related hearing loss and cognitive decline and review the four proposed causal mechanisms underlying this link. I argue that future research in this area requires greater consideration of the functional overlap between hearing and cognition. I also present an alternative framework for understanding causal relationships between age-related declines in hearing and cognition, with emphasis on the interconnected nature of hearing and cognition and likely contributions from multiple causal mechanisms. I also provide a number of testable hypotheses to examine how impairments in one domain may affect the other. In my first experimental study, I examine the direct contribution of working memory (through a cognitive training manipulation) on speech in noise comprehension in older adults. My results challenge the efficacy of cognitive training more generally, and also provide support for the contribution of sentence context in reducing working memory load. My findings also challenge the ubiquitous use of the Reading Span test as a pure test of working memory. In a second experimental (fMRI) study, I examine the role of attention in audiovisual speech integration, particularly when the acoustic signal is degraded. I demonstrate that attentional processes support audiovisual speech integration in the middle and superior temporal gyri, as well as the fusiform gyrus. My results also suggest that the superior temporal sulcus is sensitive to intelligibility enhancement, regardless of how this benefit is obtained (i.e., whether it is obtained through visual speech information or speech clarity). In addition, I also demonstrate that both the cingulo-opercular network and motor speech areas are recruited in difficult listening conditions. Taken together, these findings augment our understanding of cognitive contributions to the listening process and demonstrate that memory, working memory, and executive control networks may flexibly be recruited in order to meet listening demands in challenging environments.

Clinical interventions, implementation interventions, and the potential greyness in between - a discussion paper

Background: There is increasing awareness that regardless of the proven value of clinical interventions, the use of effective strategies to implement such interventions into clinical practice is necessary to ensure that patients receive the benefits. However, there is often confusion between what is the clinical intervention and what is the implementation intervention. This may be caused by a lack of conceptual clarity between 'intervention' and 'implementation', yet at other times by ambiguity in application. We suggest that both the scientific and the clinical communities would benefit from greater clarity; therefore, in this paper, we address the concepts of intervention and implementation, primarily as in clinical interventions and implementation interventions, and explore the grey area in between. Discussion: To begin, we consider the similarities, differences and potential greyness between clinical interventions and implementation interventions through an overview of concepts. This is illustrated with reference to two examples of clinical interventions and implementation intervention studies, including the potential ambiguity in between. We then discuss strategies to explore the hybridity of clinical-implementation intervention studies, including the role of theories, frameworks, models, and reporting guidelines that can be applied to help clarify the clinical and implementation intervention, respectively. Conclusion: Semantics provide opportunities for improved precision in depicting what is 'intervention' and what is 'implementation' in health care research. Further, attention to study design, the use of theory, and adoption of reporting guidelines can assist in distinguishing between the clinical intervention and the implementation intervention. However, certain aspects may remain unclear in analyses of hybrid studies of clinical and implementation interventions. Recognizing this potential greyness can inform further discourse.

Bailouts, monitoring, and penalties: an integrated framework of government policies to manage the too-big-to-fail problem

This paper discusses optimal government bailout policy where the costs of systemic failures and moral hazard problems are considered. We find that a three-tiered bailout policy that includes an ex post monitoring and bailout scheme for financial institutions with large systemic impacts ('too big to fail') is optimal. The optimal policy also requires a randomized bailout for medium-impact institutions ('Constructive Ambiguity'), and no bailout for institutions that have only minimal systemic consequences ('too small to save'). However, in a volatile, innovative market environment where individual institutions may know more than the government regulator, monitoring error could contribute to risk taking, leaving the government regulator to always play a 'catch-up' role in revising policy. Moreover, the optimal bailout policy may not be time-consistent: institutions not deemed 'too big to fail' may still have an incentive to take excessive risks and expect to be bailed out in case of insolvency, primarily due to the short-term orientation of the government. Finally, because an institution's systemic cost affects the probability of a bailout, we show that the boundary of an institution may be extended by the government subsidy.

Robust object detection under partial occlusion

This thesis focuses on the problem of object detection under partial occlusion in complex scenes through exploring new bottom-up and top-down detection models to cope with object discontinuities and ambiguity caused by partial occlusion and allow for a more robust and adaptive detection of varied objects from different scenes.

Merleau-Ponty's conception of dialectics in phenomenology of perception

Although the fact that Merleau-Ponty has a dialectical approach in Phenomenology of Perception has been discussed in recent Anglophone readings, there has not been an explicit clarification as to how his varying usages of the term hang together. Given his repeated references to Hegel and to dialectics, coupled with the fact that dialectics are not part of the Husserlian phenomenology or Heideggerean existentialism from which Merleau-Ponty draws so much, the question of just what he does with the idea of dialectics presents itself. In this paper I argue that, in Phenomenology of Perception, Merleau-Ponty saw Hegel as providing a model for the conception of rationality and meaning that must underpin the existentialist response to the problems bequeathed him by Husserlian phenomenology: namely, the problems of embodiment, perception and the constitution of the world. In connection with this, I suggest an interpretation of Merleau-Ponty's “existential dialectics” that focuses on his three principal uses of the term: 1) a “dialectic of objective thought,” 2) a set of existential-dialectical categories intended to capture the ontological structure of the “body-subject” as “being-in-the-world,” and 3) a dialectic at the cultural level concerning others and history.

La gestion facultaire en contexte budgétaire difficile : analyse sous l’angle de l’activité des doyens

Cette thèse examine le comportement de quatre doyens canadiens dont les facultés sont en situation financière précaire. Dans un contexte d’imputabilité accrue des établissements universitaires et de modification constante aux rapports de pouvoir internes, cette étude présente une importance particulière pour la compréhension de l’exercice réel des fonctions administratives des cadres académiques intermédiaires. La recherche scientifique sur ce sujet attribue aux doyens une contribution vitale au bon fonctionnement des établissements; le doyen en demeure pourtant un des rouages les moins étudiés. La position intermédiaire qu’occupent les doyens les place dans un conflit de rôle évident. Pris entre des rôles et des attentes contradictoires émis par la communauté facultaire, d’une part, et par la direction de l’établissement, d’autre part, ils doivent conjuguer cette ambiguïté avec des responsabilités croissantes en matière de gestion financière, de leadership et d’opérationnalisation des visées stratégiques de l’université. Comprendre la façon dont les doyens arrivent à mobiliser les leviers institutionnels à leur disposition pour résoudre des situations critiques permettra d’améliorer notre compréhension de la complexité de la prise de décision au niveau intermédiaire et notre compréhension globale du fonctionnement des établissements universitaires. La présente étude importe de la théorie culturelle-historique de l’activité (culturalhistorical activity theory, ou CHAT) un modèle d’analyse de l’activité collective en situation de contradictions systémiques. Quatre doyens d’une même université ont été interviewés afin de présenter une situation vécue de difficulté budgétaire, et le processus de résolution qui a suivi. Les données ont été analysées qualitativement afin de décrire les interventions que réalisent les doyens sur les leviers présents dans leurs environnements. Les résultats suggèrent que les participants ont misé sur une maîtrise fine des rouages institutionnels et sur des interventions diversifiées afin de résoudre les contradictions de leurs systèmes d’activité.

Determinants of the Design and Use of PMS in Portuguese Government Agencies: A Complementary Theoretical Approach

Performance measurement is seen as a main pillar of public management reforms. However, prior research did not mitigate the level of ambiguity on PMS development and use and many questions left unanswered. Our findings provide knowledge on the design and use of PMS in the public sector answer- ing to calls for a complementary approach among institutional and contingency factors. The authors find that the design of PMS and the use of performance information for external purposes are increased to legitimate the organizational’ work and to obtain external support. Moreover, structural variables such as type of agency and management autonomy are also determinants on the organizational responses. Finally, the authors find some coupling between the design of PMS and outcomes. So, both contingent and institutional approaches play an important role on the empirical model.

Alcances y límites del principio de la responsabilidad de proteger: actuación del consejo de seguridad frente al conflicto en libia en el 2011 y Siria durante el periodo 2011-2014.

El propósito de este estudio de caso es determinar los alcances y límites de la Responsabilidad de Proteger, tomando como ejemplo la actuación del Consejo de Seguridad de Naciones Unidas ante el conflicto en Libia y Siria. Para esto es necesario analizar fuentes primarias documentos oficiales y secundarias como artículos académicos, para así comprobar que la evolución del concepto de soberanía ha permitido que se legitimen las intervenciones con fines humanitarios, ya que todos los Estados tienen la responsabilidad de garantizar la protección de los derechos humanos de sus ciudadanos, de lo contrario, la comunidad internacional debe tomar medidas para evitar o detener los crímenes masivos.

Comparación de política exterior de Estados Unidos y Rusia con ocasión del conflicto en Siria (2011-2013)

El presente documento académico explica el papel del conflicto en Siria como escenario para la manifestación de la política exterior tanto de Estados Unidos como de Rusia, con el fin de demostrar que la guerra civil en Siria es una confrontación interna que se ha metamorfoseado como tensión diplomática y de confrontación de políticas exteriores de Rusia y EE.UU. Se hará uso del método de investigación cualitativo, pues este permitirá el análisis e interpretación de eventos, datos y conceptos importantes para el análisis del problema a estudiar. Por último, se hará uso de la teoría realista de las Relaciones Internacionales para tener una mejor perspectiva de los acontecimientos estudiados.

¿Quién es terrorista? Aproximación a las nociones de terrorismo en la política de seguridad democrática durante el gobierno de Álvaro Uribe Vélez

El objetivo del presente trabajo de grado es estudiar el discurso de la lucha contra el terrorismo en Colombia y dar luces al debate que giró alrededor de quien era señalado como terrorista durante el gobierno de Álvaro Uribe Vélez. Indaga sobre la instrumentalización que se ha dado al discurso de la lucha contra el terrorismo por actores políticos, quienes, en contraposición a los actores jurídicos, buscan mantener la ambigüedad del mencionado debate. Partiendo de los planteamientos de Donatella Della Porta y Charles Tilly, quienes ponen en tela de juicio la validez del terrorismo como concepto dentro de las ciencias sociales y, utilizando casos para ejemplificar cómo los actores políticos se benefician de la ambigüedad del discurso configurado alrededor del terrorismo, el presente trabajo muestra cómo se implementó este discurso en Colombia enfocándose en los actores que podían modificar la realidad a partir de su posición en el mencionado debate.

Ex combatientes y proceso de reintegración: representaciones sociales de un grupo estudiantes del área de la salud

La presente investigación tuvo como objetivo describir las representaciones sociales de un grupo de estudiantes del área de la salud frente a los excombatientes de grupos armados al margen de la ley en Colombia y frente a los procesos de reintegración. El estudio es cualitativo, desde un enfoque procesual de la teoría de las representaciones sociales, participaron estudiantes del área de la salud de una universidad privada de la ciudad de Bogotá. Los datos fueron recogidos mediante un ejercicio de asociación libre para conocer el componente semántico de las representaciones y una entrevista semiestructurada de forma individual con el fin de identificar las dimensiones de información, actitud y campo representacional. Se encontró la prevalencia de prejuicios hacia los excombatientes y la influencia de los medios de comunicación en el nivel y calidad de la información sobre estos objetos de representación, y se identificó una ambigüedad frente al proceso de reintegración; lo que de alguna forma sugiere las dificultades para la inclusión de este grupo a la sociedad, la presencia de una discriminación negativa y las bajas expectativas frente a procesos de cambio en el marco del proceso de paz.

PROPUESTA PARA LA ELABORACIÓN DE UN PLAN DE TRANSPORTE URBANO, DENTRO DEL CONTEXTO DE LOS PLANES REGULADORES EN COSTA RICA

En este artículo se plantean los elementos fundamentales que deben contener un plan de transporte, dentro del contexto de los Planes Reguladores en Costa RicaSe pretende que este documento sirva de guía metodológica en la elaboración de los planes reguladores, en la sección correspondiente al transporte y la vialidad. Actualmente existe un vacío teórico metodológico que se refleja en una ambigüedad conceptual y en una falta de rigurosidad metodológica, provocada por la interpretación que cada uno hace de las diferentes leyes de la planificación urbana que existen en nuestro país. Con el traspaso de los recursos obtenidos de la ley de bienes inmuebles a las municipalidades, se hace imperativo que la mayoría de las municipalidades, que no han elaborado un plan regulador, se aboquen a hacerlo y que numerosos consultores privados e institutos y escuelas universitarias ofrezcan esos servicios.El trabajo recoge la experiencia de varios años de investigación en ese campo y la participación en numerosos congresos y conferencias a nivel nacional e internacional.ABSTRACT:This article dcals with the principal elements which a transportation plan should contain, within the context of regulatory plan in Costa Rica.It is hoped that thís document wilI gcncrally serve as a methological guide for the design of thosc rcgulatory plans, and particulary with regard to the scction dealing with transportation and roadways.There exists at prcsent a theoretical and methodological vacuum in this area which is reflected in a conceptual ambiguity and lack of methodological discipline, due to the various individual interpretations applied to ihose urban planning laws which do exist in this country.Statutory revisions now prov ide for the allocation of proceeds from real property taxes to the municipalities, thus making it emperative that those local governments which have not done so, promptly design their own regulatory plan, and that public and private consultants, as well as institutions of learning and research, offer their specialized expertise to this effort.Morever, this anide presents the results of many years of research in Ihis area in addition to the lessons learned from a continuing participation in conferences, seminars and events of a similar nature, heid at both national and international leveis.
