El relato de guerra: Cómo el arte transmite la memoria del conflicto en Colombia
Authors: Carvajal González Johanna
Published: July 2018

La fuerza del arte se traduce en las obras de arte, con un mensaje que viaja a través del consciente, del inconsciente, de las vivencias de cada uno, para hablarnos de algo universal, humano, esencial. El rol del arte en la coyuntura actual de Colombia –período llamado de posconflicto, o mejor, de posacuerdo de paz–, es el de recordarnos quienes somos, en cuanto seres emocionales, racionales y sociales. De la misma manera, el arte se convierte en un canal a través del cual se transforman las narraciones íntimas en una voz colectiva, que denuncia las situaciones que la sociedad se niega a vivir de nuevo.A través del análisis de la obra teatral “Mujeres en la guerra! (2001) dirigida por Fernando Montes, de la obra fotográfica “El David” (2006) de Miguel Ángel Rojas y de la obra visual de Juan Manuel Echavarría titulada “Silencios” (2010), se percibe que las narraciones del conflicto fueron punto de partida de la obra y, al mismo tiempo, el eje central de las mismas. Narraciones que se conjugan con el discurso estético, que revela la humanidad detrás del conflicto, discurso que constituye una probable reparación simbólica de las víctimas. El arte está presente para recordar que es posible reivindicar los abusos sufridos durante este período violento, que ha durado más de cincuenta años.
El conflicto colombiano entre animación e hiperrealismo mágico : Desterrada de Diego Guerra.
Authors: Bouvet Françoise
Published: July 2018

En marzo de 2014 se estrenó en el Festival Internacional de Cine de Cartagena de Indias la película de animación Desterrada. Con este primer largometraje, el historietista Diego Guerra pretende contar lo que es ser joven en Bogotá al mismo tiempo que procura retratar el conflicto que carcome a Colombia desde los años 70. Reflejo de la Historia del país o ficción, hiperrealista pero también distópica, la película estremece por su peculiar tratamiento de la violencia, llevándonos de un proceso de rememoración a una denuncia del conflicto. Con claras influencias del cine y del cómic norteamericanos, pero con raíces artísticas profundamente colombianas, veremos cómo se inscribe esta película de animación en un proyecto estético original, y cuestionaremos esta apelación de “hiperrealismo mágico” que surgió entre los espectadores después del estreno.
Comment raconter l’horreur ? Métaphore et déplacement dans les chroniques de guerre d’Enrique Gómez Carrillo
Authors: Coto-Rivel Sergio
Published: July 2018

L’écrivain guatémaltèque Enrique Gómez Carrillo (1873-1921), diplomate et voyageur, a laissé une œuvre très importante en tant que « reporter de guerre ». Ses chroniques publiées à partir de 1914, et très rapidement recueillies sous forme de livre dès 1915, se chargent non seulement d’informer le public, mais surtout de développer une importante réflexion sur l’homme, la destruction des grandes œuvres culturelles et les vices de la guerre. Nous analysons dans cet article la construction du discours moderniste comme une possibilité de raconter les horreurs de la guerre et les témoignages de ceux qui l’ont vécue. Nous nous concentrons sur les stratégies de déplacement métaphorique développées par l’auteur pour comprendre et expliquer le contexte belliqueux et la destruction. L’utilisation de la métaphore riche en formes et couleurs dans les chroniques parisiennes de Gómez Carrillo prend ici un tournant significatif dans le but de faire face aux particularités de la « guerre moderne ».
Música en el tiempo y el silencio : narración del conflicto armado a través de la música popular
Authors: Roa Diana Paola Castro
Published: July 2018

Con más de 50 años de conflicto armado,la violencia se ha reproducido por todo el territorio Colombiano,la guerra tuvo repercusiones directas en la ruralidad del país, pero también afectó las maneras de habitar los centros urbanos. Dentro de las cargas culturales fruto de la convivencia con el conflicto, la música popular juega un rol de memoria e identidad. Este trabajo analiza una selección de temas musicales creados entre 1945 y 1970 en relación al conflicto interno, al contraponer la creación artística-musical con la evolución histórica del conflicto armado. Si bien la violencia en Colombia incide en todos sus habitantes,la música popular -al ser creadas por ciudadanos de a pie- contiene en sus letras y discurso la postura de quienes han vivido el conflicto de manera directa. El texto tiene como base el libro Contribución al entendimiento del conflicto armado en Colombia y los informes del conflicto armado del Centro nacional de Memoria histórica. Los conceptos de etnomusicología se desarrollan con base a los planteamientos de Catherine Héau Lambert (2005) acerca las representaciones de las relaciones de poder en la música popular, también se toma como referente el trabajo de Ana María Ochoa (2003)que teoriza la hibridación musical en Colombia.
David y Cuerpo gramatical : imágenes de la violencia y políticas de la mirada en dos casos del arte contemporáneo en Colombia
Authors: García Daniel
Published: July 2018

Este artículo reflexiona sobre dos obras del arte contemporáneo en Colombia (David de Miguel Ángel Rojas y Cuerpo gramatical, de José Alejandro Restrepo), con el propósito de explicar los motivos por los cuales estos artistas aludieron a la iconografía cristiana y clásica para abordar el problema de la violencia moderna y contemporánea en el país. La hipótesis central del texto es que, en ambos casos, la estrategia de estas obras consiste en proponer una política de la mirada que sirve para elaborar una crítica de los procesos de producción, circulación y recepción de las representaciones de la violencia pública en los medios masivos de información. Ante los mecanismos de aislamiento y prescripción que se les suele imponer a este tipo de representaciones, las obras de estos artistas permiten integrarlas en el ámbito de una cultura visual de larga duración, además de abordar con criterio distinto el problema de su significación.
El Dorado o la búsqueda de los migrantes colombianos en España
Authors: Bazurto Victoria
Published: July 2018

The Muisca legend of El Dorado fed the imaginary from a lot of conquistadors and has also motivated hundredth of expeditions. It’s a legend that has been broadly interpreted and integrated into the language related to the migratory contemporary universe in general but also into that one related to the Colombian migration. Based on this, the major goal of this paper is to present the way an imaginary around Spain as a new El Dorado for the Colombian migrants is built. Colombians represents in 2015 the second Latin-American community in that country just after the Ecuadorians. We will address the analysis based on the Colombians newspapers El Tiempo and El Espectador and the Spanish newspapers El País and El Mundo all over the period between 1990 and 2005.
L’émergence de l’individualité comme modalisateur du discours politique chez les popolani florentins
Authors: Rivière Jean-Marc

De l’usage politique du peuple Padano
Authors: Ivaldi Gilles , Lanzone Maria Elisabetta
Published: July 2018

En Italie, le « peuple » de la Lega Nord (Ligue du Nord) s’est adossé originellement au façonnage d’une identité « padane » sans réel substrat culturel ou géographique. Au fil du temps, de nouvelles frontières sociales et symboliques ont été dessinées, complétées plus récemment par un repositionnement au cœur de l’espace des droites radicales populistes en Europe. Cette complexité tient en partie à la nature opportuniste et caméléonienne du régional-populisme « léguiste », et au statut hybride du mouvement, entre force de coalition gouvernementale et parti d’opposition. Elle illustre en outre la variabilité des structures d’opportunités politiques qui existent au nord et au sud de l’Italie.
Du statut d’objet technique à celui d’objet social dans le contexte de la production automatisée d’informations journalistiques
Authors: Dierickx Laurence
Published: July 2018

« Bxl’air bot » consiste en une application de monitoring de la qualité de l’air bruxellois réalisée en collaboration avec la rédaction d’Alter Échos, un magazine belge dédié aux actualités sociales. Cette application automatisée est à comprendre comme un objet du journalisme, dont la matérialité est assurée par des publications fondées sur une collecte en temps réel des données relatives à la pollution de l’air ambiant. Au-delà de ce cadre serviciel, elle est également à comprendre comme un outil du journalisme. En enregistrant chaque jour les données relatives aux mesures des polluants atmosphériques dans une base de données, cette dernière permet d’en retracer l’historique et de livrer une analyse statistique. Historique et analyse serviront de base à un projet, plus large, d’enquête journalistique couvrant une période d’un an. La problématique de la qualité de l’air à Bruxelles peut être ici considérée comme un problème public, lequel consiste en la transformation d’un fait social en enjeu de débat public et/ou d’intervention étatique. La quantification, dans le contexte d’un problème public, permet d’assurer une objectivation chiffrée d’une situation donnée. Cet article examine en quoi cette application est le résultat d’interactions entre technique et social, dans la perspective d’interroger les boîtes noires du journalisme et de la technologie.
La participation numérique en urbanisme, une simple amplification des processus existants ?

Published: July 2018

Les données récoltées sur les plateformes numériques de participation citoyenne apportent-elles des opportunités ou des menaces en matière de participation à l’amélioration de l’aménagement de la ville ? Comment ces plateformes se situent-elles par rapport aux outils préexistants de concertation ou de co-création ? Redondance, complémentarité, remplacement ? Afin d’esquisser des pistes de réponses à ces interrogations globales qui interpellent architectes, urbanistes et responsables au sein des villes wallonnes, cette recherche étudie la mise en place et les premiers mois d’exploitation de la plateforme « Demain, Mons ». L’article passe en revue la plateforme ainsi que ses résultats et s’interroge sur la double question suivante : cette technique, qui suscite un engouement peu discuté, est-elle une simple amplification des processus existants ou nécessite-t-elle en amont un débat démocratique plus poussé sur la gouvernance urbaine ? Les mécanismes participatifs initiés dans les années 1970 (rompant la collusion entre architecture, urbanisme et pouvoirs) seront-ils maintenus, renforcés ou désagrégés par l’émergence du numérique ? Les résultats de la recherche permettent d’identifier les opportunités qui existent, de renforcer la participation par les innovations numériques, mais aussi les menaces qui augmentent le risque de voir le pouvoir citoyen se désagréger au sein d’une nouvelle gouvernance.
Treat patient, not just the disease: holistic needs assessment for haematological cancer patients
Authors: Islam Md Serajul
Published: July 2018

Haematological malignancies can have devastating effects on the patients’ physical, emotional, psycho-sexual, educational and economic health. With the improvement of therapies patients with these malignancies are living longer, however significant proportion these patient show poor quality of life (QoL) due to various physical and psychological consequences of the disease and the treatments. Health-related QoL (HRQoL) is multi-dimensional and temporal, relating to a state of functional, physical, psychological and social/family well-being. Compared with the general population, HRQoL of these patients is worse in most dimensions. However without routine holistic need assessment (HNA), clinicians are unlikely to identify patients with clinically significant distress. Surviving cancer is a chronic life-altering condition with several factors negatively affecting their QoL, such as psychological problems, including depression and excessive fear of recurrence, as well as social aspects, such as unemployment and social isolation. These need to be adequately understood and addressed in the healthcare of long-term survivors of haematological cancer. Applying a holistic approach to patient care has many benefits and yet, only around 25% of cancer survivors in the UK receive a holistic needs assessment. The efforts of the last decade have established the importance of ensuring access to psychosocial services for haematological cancer survivors. We need to determine the most effective practices and how best to deliver them across diverse settings. Distress, like haematological cancer, is not a single entity, and one treatment does not fit all. Psychosocialoncology needs to increase its research in comparative effectiveness.
Conditions for coaching to contribute to the adjustment of black African professionals
Authors: Le Sueur Heidi M. , Tapela Valerie
Published: July 2018

Orientation: Efforts to attract and retain black African professionals in Cape Town-based organisations are often met with challenges. Coaching has been identified as a potential strategic contributor for developing a sense of inclusivity and successful adjustment for black African professionals.Research purpose: The study investigated the contribution that coaching makes and aimed at understanding the conditions required for coaching to support the adjustment process during relocation.Motivation for the study: Too little is known in South Africa of how coaching can impact the adjustment during relocation. There is a need to identify key conditions that would enable a successful coaching process for migrating groups in the larger South African context.Research design/approach and method: A qualitative inductive methodology approach was followed to guide the study, consisting of 11 in-depth interviews with three different professional groups to elicit various perspectives.Main findings: It can be concluded that coaching contributes to black African professionals’ adjustment to living and working in South Africa. The success of the coaching outcome and capability for adjustment depends on the individual, the coach and the environment in which they work. The supporting conditions that were commonly found from the three professional groups were support and space for the individual, while depth and match played a key role according to coaches and human resource (HR) professionals.Practical/managerial implications: This article provides guidelines and recommendations for HR and senior managers in any organisation that experiences a complexity infused by racial and cultural diversity within its internal and external context. The study shows ways in which coaching as a tool can be useful in dealing with cross-cultural dynamics that prevail in South Africa and South Africa-based organisations especially during relocation adjustment.Contribution/value-add: The body of knowledge contributes to understanding coaching in a diverse society reflected in cross-cultural organisations and the key conditions influencing the coaching intervention during an adjustment process.
Critical evaluation of the factors affecting Escherichia coli environmental decay for outfall plume models
Authors: Carneiro Marcos Tavares , Cortes Myriam Bandeira Vianna , Wasserman Julio Cesar
Published: July 2018

The Escherichia coli T90 parameter is widely employed in outfall plume hydrodynamic models. Although there is a great deal of academic literature estimating T90, no standard methodology has been validated so far. Estimation of die-off rates should consider many other biological, chemical and physical processes. Over the last three decades, while a great deal of new knowledge about microbial biology and ecology has become available, it has not been fully incorporated into the overall research. Consequently, hydrodynamic models of sewage plumes lack consistency with environmental dynamics and frequently do not fully reproduce processes. This article scrutinized the relevant works that could improve T90 assessment using the most robust and realistic approaches. The most important related literature since the 1990s was considered, together with earlier relevant works. The research focused on techniques and methodologies, especially their ecologic and cellular biology aspects. A brief discussion of the methods applied to evaluate the T90 of bacteria examined aspects like representativeness of incubation, incubation scale, measurement procedures and models’ representations of bacterial decay. The factors affecting population decay, such as solar radiation, salinity and interaction with solids, were considered in the light of the very large literature registry. Finally, biological aspects affecting decay, like predation and genetic resistance, were also analyzed. The resulting updated understanding of T90 may contribute to better managerial procedures that could improve water quality in freshwater and coastal systems, and consequently improve human health outcomes.

High occurrence of new particle formation events at the Maïdo high-altitude observatory (2150 m), Réunion (Indian Ocean)
Authors: Foucart Brice , Sellegri Karine , Tulet Pierre , Rose Clémence , Metzger Jean-Marc , Picard David
Published: July 2018

Abstract. This study aims to report and
characterise the frequent new particle formation (NPF) events observed at the
Maïdo observatory, Réunion, a Southern Hemisphere site located at
2150 m (a.s.l.) and surrounded by the Indian Ocean. From May 2014 to December
2015, continuous aerosol measurements were made using both a differential
mobility particle sizer (DMPS) and an air ion spectrometer (AIS) to
characterise the NPF events down to the lowest particle-size scale. Carbon
monoxide (CO) and black carbon (BC) concentrations were monitored, as well as
meteorological parameters, in order to identify the conditions that were
favourable to the occurrence of nucleation in this specific environment. We
point out that the annual NPF frequency average (65 %) is one of the
highest reported so far. Monthly averages show a bimodal variation in the NPF
frequency, with a maximum observed during transition periods (autumn and
spring). A high yearly median particle growth rate (GR) of 15.16 nm h−1
is also measured showing a bimodal seasonal variation with maxima observed in
July and November. Yearly medians of 2 and 12 nm particle formation rates
(J2 and J12) are 0.858 and 0.508 cm−3 s−1, respectively,
with a seasonal variation showing a maximum during winter, that correspond to
low temperature and RH typical of the dry season, but also to high BC
concentrations. We show that the condensation sink exceeds a threshold value
(1.04×10−3 s−1) with a similar seasonal variation than
the one of the NPF event frequency, suggesting that the occurrence of the NPF
process might be determined by the availability of condensable vapours, which
are likely to be transported together with pre-existing particles from lower
altitudes.
High- and low-temperature pyrolysis profiles describe volatile organic compound emissions from western US wildfire fuels

Abstract. Biomass burning is a large source of volatile organic compounds
(VOCs) and many other trace species to the atmosphere, which can act as
precursors to secondary pollutants such as ozone and fine particles.
Measurements performed with a proton-transfer-reaction time-of-flight mass
spectrometer during the FIREX 2016 laboratory intensive were analyzed with
positive matrix factorization (PMF), in order to understand the
instantaneous variability in VOC emissions from biomass burning, and to
simplify the description of these types of emissions. Despite the complexity
and variability of emissions, we found that a solution including just two
emission profiles, which are mass spectral representations of the relative
abundances of emitted VOCs, explained on average 85 % of the VOC emissions
across various fuels representative of the western US (including various
coniferous and chaparral fuels). In addition, the profiles were remarkably
similar across almost all of the fuel types tested. For example, the
correlation coefficient r2 of each profile between ponderosa pine
(coniferous tree) and manzanita (chaparral) is higher than 0.84. The
compositional differences between the two VOC profiles appear to be related
to differences in pyrolysis processes of fuel biopolymers at high and low
temperatures. These pyrolysis processes are thought to be the main source of
VOC emissions. “High-temperature” and “low-temperature” pyrolysis
processes do not correspond exactly to the commonly used “flaming” and
“smoldering” categories as described by modified combustion efficiency
(MCE). The average atmospheric properties (e.g., OH reactivity, volatility,
etc) of the high- and low-temperature profiles are significantly different.
We also found that the two VOC profiles can describe previously reported VOC
data for laboratory and field burns.
Characterization of blackbody inhomogeneity and its effect on the retrieval results of the GLORIA instrument
Authors: Kleinert Anne , Krisch Isabell , Ungermann Jörn , Adibekyan Albert , Gutschwager Berndt , Monte Christian
Published: July 2018

Abstract. Limb sounding instruments play an important role in the monitoring of climate
trends, as they provide a good vertical resolution. Traceability to the
International System of Units (SI) via onboard reference
or transfer standards is needed to compare trend estimates from multiple
instruments. This study investigates the required uncertainty of these
radiation standards to properly resolve decadal trends of climate-relevant
trace species like ozone, water vapor, and temperature distribution for the
Gimballed Limb Observer for Radiance Imaging of the Atmosphere (GLORIA).
Temperature nonuniformities of the onboard reference blackbodies, used for
radiometric calibration, have an impact on the calibration uncertainty. The
propagation of these nonuniformities through the retrieval is analyzed. A
threshold for the maximum tolerable uncertainty of the blackbody temperature
is derived, so that climate trends can be significantly identified with
GLORIA.
To what degree the geometry and kinematics of accretionary wedges in analogue experiments is dependent on material properties
Authors: Jiang Ziran , Deng Bin , Fan Caiwei , He Yu , Lai Dong , Liu Shugen , Wang Xinjian , Jansa Luba
Published: July 2018

Abstract. Cohesion and friction coefficients are fundamental parameters of granular materials used in analogue experiments. Thus, to test the physical characteristics and mechanical behaviour of the materials used in the experiments will help to better understand into what degree the results of experiments of geological processes depend on the material properties. Our test suggests significant differences between quartz sand and glass bead, in particular the shape factors (~ 1.55 of quartz sand to ~ 1.35 glass bead, angular to rounded) and grain sorting (moderately to well sorted). The glass beads show much better grain sorting and smaller shape factors than the quartz sand. Also they have smaller friction coefficient (~ 0.5 to ~ 0.6) and cohesion (20–30 Ma to 70–100 Ma), no matter of the grain size in our tested samples. The quartz sand shows much smaller friction coefficient (~ 0.6 to ~ 0.65), and smaller cohesion (~ 70 Pa to ~ 100 Pa) than that of smaller grain size sand. We have conducted four sets of analogue experiments with three repeats at the minimum. Our models show that material properties have important influence on the geometry and kinematics of the accretionary wedge. Although the difference in geometries are small, models with larger grain size develop wedges with higher wedge height, larger taper, shorter wedge length and less number of faults under the same amount of bulk shortening. In particular, models with basal detachment (even with 1 mm thickness), show significant difference in geometry and kinematics with that of quartz sand. We thus argue that the geometry and kinematics of the wedge appear to be significantly influenced by relative brittle and ductile strengths, and, to a lesser degree by the layering anisotropy. The basal detachment (even of tiny thickness) determines the first-order control on the location and development of accretionary wedge, in a contrast to the physical properties of brittle materials.
Scale-adaptive simulation of wind turbines, and its verification with respect to wind tunnel measurements
Authors: Wang Jiangang , Wang Chengyu , Campagnolo Filippo , Bottasso Carlo L.
Published: July 2018

Abstract. This paper considers the application of a scale-adaptive simulation (SAS) CFD formulation for the modeling of single and waked wind turbines in flows of different turbulence intensities. The SAS approach is compared to a large-eddy simulation (LES) formulation, as well as to experimental measurements performed in a boundary layer wind tunnel with scaled wind turbine models. The motivation for the use of SAS is its significantly reduced computational cost with respect to LES, made possible by the use of less dense grids. Results indicate that the two turbulence models yield in general results that are very similar, in terms of rotor-integral quantities and wake behavior. The matching is less satisfactory in very low turbulence inflows. Given that the computational cost is about one order of magnitude smaller, SAS is found to be an interesting alternative to LES for repetitive runs where one can sacrifice a bit of accuracy for a reduced computational burden.
Inter-annual variability of wind climates and wind turbine annual energy production
Authors: Pryor Sara C. , Shepherd Tristan J. , Barthelmie Rebecca J.
Published: July 2018

Abstract. Inter-annual variability (IAV) of expected annual energy production (AEP) from proposed wind farms plays a key role in dictating project financing. IAV in pre-construction projected AEP and the difference in 50th and 90th percentile (P50 and P90) AEP derives in part from variability in wind climates. However, the magnitude of IAV in wind speeds at/close to wind turbine hub-heights is poorly constrained and maybe overestimated by the 6 % standard deviation of annual mean wind speeds that is widely applied within the wind energy industry. Thus there is a need for improved understanding of the long-term wind resource and the inter-annual variability therein in order to generate more robust predictions of the financial value of a wind energy project. Long-term simulations of wind speeds near typical wind turbine hub-heights over the eastern USA indicate median gross capacity factors (computed using 10-minute wind speeds close to wind turbine hub-heights and the power curve of the most common wind turbine deployed in the region) that are in good agreement with values derived from operational wind farms. The IAV of annual mean wind speeds at/near to typical wind turbine hub-heights in these simulations is lower than is implied by assuming a standard deviation of 6 %. Indeed, rather than in 9 in 10 years exhibiting AEP within 0.9 and 1.1 times the long-term mean AEP, results presented herein indicate that over 90 % of the area in the eastern USA that currently has operating wind turbines simulated AEP lies within 0.94 and 1.06 of the long-term average. Further, IAV of estimated AEP is not substantially larger than IAV in mean wind speeds. These results indicate it may be appropriate to reduce the IAV applied to pre-construction AEP estimates to account for variability in wind climates, which would decrease the cost of capital for wind farm developments.

Este estudo verificou a persistência na variância e a ocorrência de quebras estruturais nas séries de preços da manga e uva exportadas da Bahia, Brasil, dada a simultaneidade desses fatos que prejudicam a eficiência dos modelos de gestão de risco financeiro que consideram a variância como medida desse risco. Empregou-se o modelo GARCH(1,1) para identificação da persistência na variância e um modelo puro de variância Markov Switching (MS) para a identificação das quebras estruturais. Sobre a persistência na variância, ela não foi evidenciada em qualquer das séries históricas analisadas. Sobre as quebras estruturais, ainda que elas não tenham sido encontradas, o modelo puro de variância MS conseguiu somente lidar com a heterocedasticidade presente na série histórica da manga, enquanto que para a série histórica da uva, o modelo GARCH(1,1) atendeu melhor nesse quesito. Isto sugere certa “imunidade” dessas séries históricas frente às mudanças macroeconômicas internacionais ocorridas entre 1989 e 2014.

Authors: Condé Giovanni Cláudio , Martens Mauro Luiz
Published: July 2018

Portfólio de projetos é um assunto da mais alta importância dentro do campo de gerenciamento de projetos. A atividade de seleção de projetos é considerada crítica para o portfólio de projetos por diversos pesquisadores.  Este estudo tem como objetivo identificar um rol dos principais projetos Lean Manufacturing de acordo com a literatura científica. A metodologia utilizada foi a revisão sistemática da literatura. A principal contribuição é a identificação de um rol de 11 principais projetos Lean Manufacturing, por meio de análises cruzadas dos conteúdos dos principais artigos de Lean Manufacturing publicados nos últimos 20 anos. Além disso, o estudo permitiu a percepção quanto ao grau relativo de disseminação de cada um destes projetos Lean na literatura. Como contribuição prática, o rol de projetos Lean poderá ser utilizado para a geração de portfólio e pela seleção dos projetos, considerados, respectivamente, como lacuna de pesquisa e fator chave de sucesso em gerenciamento de projetos.
DIREITOS HUMANOS DO TRABALHADOR E OS LIMITES AO EXERCÍCIO DO PODER DE DIREÇÃO: O DANO EXISTENCIAL NO ÂMBITO DO DIREITO DO TRABALHO
Authors: Gomes Pereira Eddla Karina , Pedroza de Castro Élida Raianne
Published: July 2018

O dano existencial é a ofensa à integridade física e/ou psíquica de um indivíduo que, no âmbito das relações de trabalho, tem como sujeito passivo o trabalhador. Diante do crescente contexto de violação à dignidade dos trabalhadores no Brasil, é relevante a discussão sobre o dano existencial na seara trabalhista e sua repercussão no gozo de direitos fundamentais. Isto porque excessos no exercício do poder de direção acabam por ampliar deliberadamente o estado de subordinação do empregado. Neste sentido, desenvolver-se-á uma pesquisa bibliográfica e exploratória sobre o dano existencial no Brasil, atentando para a posição assumida pela Justiça do Trabalho. Em sede de conclusão, observa-se que a jurisprudência brasileira tem admitido o reconhecimento da aplicabilidade do conceito de dano existencial, sobremaneira em face da necessidade premente do desestímulo de práticas desta natureza.
Creating Rituals
Authors: Thompson Becky
Published: July 2018

What rituals of inclusion do we need as teachers to allow students to keep their hearts open as they learn about social justices? What work do faculty need to do so that students can express their emotions when studying about the Middle Passage, rape, police brutality, sexual harassment, genocide, and other injustices? Allowing time for students to learn each other’s names and their genealogies, creating space for “stories that have been caught in our throats,” and making room for students’ anger are all steps for creating embodied classrooms. Incorporating free writing, taking circles, yoga, meditation, and closing circles can help students stay focused while modeling self-care. In this technological era where people are increasingly tied to their phones and computers, rituals of inclusion become an antidote and way of encouraging deep communication. These rituals also allow students who have been slated not to see each other—across race, language, culture, sexuality, and religion—to recognize each other in more complete ways. With a dramatic increase in depression, addiction, and anxiety among college students, these rituals also help students to get real with each other, to learn that they are not alone.
Our Bodies in the World
Authors: Thompson Becky
Published: July 2018

What might bringing tenderness into the world look like? Student activism and willingness to explore historical memory from their own families often illuminate lived examples of tenderness. The life changing experience Thompson had as a first responder during the refugee crisis in Lesvos, Greece (2015-2016), as I met Syrian, Afghan, Palestinian, and Pakistani families coming on rafts from Turkey, taught her much about tenderness as a quality of being with each other. Refugee families modeled tenderness for her as they risked their lives to save their lives.
While militarism, colonialism, racism, and patriarchy remain structural impediments to tenderness, as teachers we find ourselves seeking renewal, knowing that, as Angela Davis has written, “without deep, abiding practices of self care, there can be no radical social transformation.” So this is where we start, rethinking our relationship to our bodies, grading, office hours, faculty meetings, and methods of evaluation. We want to send students off ready to do justice work. Such work may start with examining what the Turkish poet Nazim Hikmet has called the “jewel at the left side of your chest.” Our own jewels in this lifetime.
Color-Blind Conservatism and the Great White Switch
Authors: Bedingfield Sid
Published: July 2018

This chapter details the effort by former segregationist editors to unite whites against rising black political clout after passage of the Civil Rights Act in 1964 and the Voting Rights Act in 1965. The editors at the state’s two largest newspaper, Thomas R. Waring Jr. at the News & Courier in Charleston and William D. Workman Jr., at The State in Columbia, helped develop a rhetoric of “color-blind conservatism” to undermine black political activism. The new rhetoric accepted the end of segregation and legal equality for blacks in the South, but declared that racial issues should no longer be an acceptable topic for political debate. It identified blacks as special pleaders seeking aid from government that they did not deserve.
Respectability and Reform
Authors: Case Sarah H.
Published: July 2018

This chapter focuses on the relationship of Spelman women to their education as students and alumnae between the 1880s and the 1920s. The African American women who attended Spelman Seminary incorporated the message of the seminary with values they learned from their families, churches, and community to fashion their own definition of respectable Christian womanhood. Although accepting the school’s message of moral improvement, alumnae perceived it as a means to attain leadership and an opportunity to work for individual and social uplift. Spelman alumnae viewed their cultivation of personal respectability, their work as homemakers and professionals, and their church and club organizations as their responsibility as educated women and as part of their quest for social and racial justice.
Meet the Political Class
Authors: Formisano Ron
Published: July 2018

The hub of thepolitical class is Washington, D.C., but it embraces networks, families, and individuals working and living across the country. The nation’s capital is awash, if not inundated a populace, as Mark Leibovich described it in This Town, “trained to view human interaction through the prism of ‘How can this person be helpful to me?’”
Political Class Adaptation and Expansion
Authors: Formisano Ron
Published: July 2018

The permanent political class has expanded well beyond government. It protects itself and adapts also by employing populist rhetoric continually assuring “the American people” that it has their interests at heart.

Epic Revitalization
Authors: Harris Robin P.
Published: July 2018

Summarizing the vast changes across the Russian Federation that left their mark on olonkho performance practice, this chapter focuses on a few of the factors that have played a large role in the widespread view of olonkho as a national ideal rather than for its entertainment value. Topics include negotiations of cultural, religious, and political identity, along with related issues of nostalgia, festivals, and postcolonial and neocolonial tensions with the Center. Chapter 6 also examines lessons learned from the revitalization of two other Asian epic traditions, the Kyrgyz Manas and Korean p’ansori, then outlines some conclusions regarding common challenges of revitalizing living (improvisational) epic traditions.
Bring Home the Bacon
Authors: Moore Louis
Published: July 2018

By the 1890s, for a number of black leaders, the black fighter epitomized the hope of black America. Seen in the context of labor, race, and uplift politics, although race men struggled to come to terms with the reality that prizefighting represented legitimate labor and not leisure, and worried that fighters’ recalcitrant behavior outside the ring would hamper racial uplift according to many race leaders, the black prizefighters’ fistic success represented black competence, work ethic, and grit and proved that blacks could succeed in the racist market economy if given an equal chance to compete in America and overcome white racism.
Exploring Shame
Authors: Stearns Peter N.
Published: July 2018

This chapter lays out standard current definitions of shame, including the predominant belief, among psychologists, that shame is a damaging emotion. Some disagreements are noted, and particular attention is paid to the juxtaposition of psychological with sociological views, where differing emphases on the individual experience versus the social value and context are suggestive.
The Impact of Modernity
Authors: Stearns Peter N.
Published: July 2018

This brief chapter explores the general proposition that shame has declined in modern societies, and some of the reasons that have been advanced. The chapter also, however, introduces important comparative considerations, particularly around the continued acceptance of shame in East Asian cultures.
Voices of the Occupation
Authors: Vaillant Derek W.
Published: July 2018

During the German occupation of France (1940-44), in addition to the broadcasts of the British Broadcasting Corporation (BBC), shortwave broadcasters in the United States, such as NBC, and later, the U.S. government’s Voice of America (VOA) and Office of War Information (OWI) supplied broadcast news, entertainment, and moral support to French listeners living under the Vichy regime. This chapter explores U.S. and Allied international broadcasting to France between 1937, when daily transatlantic French-language programs began in earnest from America, through D-Day, to the liberation of Paris coordinated in part via radio broadcasting. The chapter analyzes the programs and strategies of broadcasters, Nazi and Vichy propagandists, and clandestine listeners during the Occupation.
