Possible splitting of deconfinement and chiral transitions in strong magnetic fields in QCD

We show that finite-temperature deconfinement and chiral transitions can split in a strong enough magnetic field. The splitting in critical temperatures of these transitions in a constant magnetic field of a typical LHC magnitude is of the order of 10 MeV. A new deconfined phase with broken chiral symmetry appears.Comment: 4 pages, 6 figures; talk given by E. S.

Coastal and marine protected areas in Mexico

This study on marine protected areas (MPAs) in Mexico relies on a variety of data sources as well as the authors’ longstanding field experience, particularly in the Yucatan Peninsula, to analyze the design, establishment and operation of protected areas. It discusses two case studies of MPAs in detail and summarizes the findings from four others, focusing primarily on the role played by local communities in managing coastal and marine resources. The study also draws on the perspective of key informants, namely, Mexican experts on coastal and ocean management issues, including government officials, decisionmakers, researchers, members of non governmental organizations (NGOs), and consultants.

Risk and Uncertainty in Yucatán (México) Fisheries Sector: Gradual Transition to the Third Economy Through tourism Development

The history of commercial fishing activity in Yucatan coast has almost seventy years. In the late ten years, the fishing activity is in process of transit to another sector related to tourism (recreational) activity. At the same time the government promote other alternatives to fishing without take into account the sociodemographic consideration (migration labor force, ethnic group, religious status), economic drivers (urban and tourism development, economic mobility of labor force) and environmental problems (marine protected areas, environmental laws). Actually, in Yucatan coast there are 16, 000 fishers that combine three and seven comercial fisheries (octupus, lobster and groupers) to obtain livelihoods conditions. Seasonality in fishing and tourism is more and more the high condition to maritime households to survive. In this paper, I highlight these controversial issues with a anthropological perspective after two decades of research taking three fishing communities like cases studies from Yucatan coast. The causes and consequences of this gradual and rapid transition from fishing to tourism are closely related to globalization of economy and culture that marginalize the fishers more than others economic actors.Keywords: Fisheries and Coastal Zone Management, Fisheries Economics, Fishery ManagementKeywords: Fisheries and Coastal Zone Management, Fisheries Economics, Fishery Managemen

Comunidades y actores sociales en áreas marinas protegidas del Caribe (México, Cuba y República Dominicana)

Este capítulo sobre comunidades y actores sociales en Áreas Marinas Protegidas (AMP) presenta los resultados de una investigación realizada sobre el manejo de recursos costeros en el Caribe desde una perspectiva etnográfica y pan-caribeña. Los tres estudios de caso presentados, ubicados en México, República Dominicana y Cuba, contribuyen a evidenciar aquellos elementos clave que demuestran la heterogeneidad de esta área geográfica. Encontramos variaciones en relación con los enfoques de manejo empleados en cada país en particular. Este cambio va de un enfoque de arriba hacia abajo, en los casos de República Dominicana y Cuba a un enfoque de abajo hacia arriba, en el caso de México. Este capítulo explora, además, la dinámica de las comunidades en relación con las diferentes categorías de manejo de las áreas naturales protegidas, así como con asuntos relacionados con los valores medioambientales de las comunidades caribeñas

Communities and stakeholders in marine protected areas in the Caribbean

This chapter on communities and stakeholders in marine protected areas (MPAs) presents the results of research into Caribbean coastal resource management from an ethnographic and a pan-Caribbean perspective. Three case studies in Mexico, the Dominican Republic, and Cuba help reveal key elements that demonstrate the heterogeneity of this geographic area. We found a gradient with respect to the management approaches used by each country, which shifts from a top-down approach in the Dominican Republic and Cuba to a bottom-up approach in Mexico. This chapter also examines community dynamics with respect to different categories of management for natural protected areas, as well as issues surrounding the environmental values of Caribbean communities

Personalization and standardization in professional services: a case study in a management consulting company

As empresas de consultoria de gestão são caracterizadas como intensivas em conhecimento, com alto nível de interação com os clientes, alto grau de discrição dos funcionários, alta complexidade das atividades desenvolvidas e alto grau de personalização. Portanto, são caracterizadas como prestadoras de serviços personalizados ou pouco padronizados. A despeito desta caracterização, algumas empresas deste setor expandiram de maneira intensa por meio da criação de um portfólio delimitado de produtos ou soluções. Esta forma de atuação coloca em questão a forma como estas empresas são classificadas. Portanto, o presente artigo busca compreender o clássico trade-off entre a personalização e a padronização de serviços para empresas deste tipo. Para tanto, utilizando-se do estudo de múltiplos casos, três casos de aplicação de uma mesma solução foram analisados em relação à dezessete parâmetros selecionados. Verificou-seque o serviço é desenvolvido para atender às necessidades e especificações de cada um de seus clientes de modo personalizado, entretanto o modo de implementação da solução é padronizado. Constatou-se que a personalização de serviços pode ser vista como um resultado da combinação de produtos e processos, sendo alguns deles padronizados e outros personalizados

Molecular mechanisms of Zika virus teratogenesis from animal studies : a systematic review protocol

Background: Due to the diversity of studies in animal models reporting that molecular mechanisms are involved in the teratogenic effect of the Zika virus (ZIKV), the objective of the present study is to evaluate the methodological quality of these studies, as well as to demonstrate which genes and which molecular pathways are affected by ZIKV in different animal models. Methods: This search will be performed in four databases: PubMed/MEDLINE, EMBASE, Web of Science, and Scopus, as well as in the grey literature. The studies selection process will be reported through the PRISMA Statement diagram model. All studies describing the molecular mechanisms possibly involved in the development of malformations caused by embryonic/fetal ZIKV exposure in animal models with an appropriate control group and methodology will be included (including, for instance, randomized and non-randomized studies). All animals used as experimental models for ZIKV teratogenesis may be included as long as exposure to the virus occurred during the embryonic/fetal period. From the selected studies, data will be extracted using a previously prepared standard form. Bias risk evaluation will be conducted following the SYRCLE’s Risk of Bias tool. All data obtained will be tabulated and organized by outcomes (morphological and molecular). Discussion: With the proposed systematic review, we expect to present results about the methodological quality of the published studies with animal models that investigated the molecular mechanisms involved in the teratogenic effect of ZIKV, as well as to show the studies with greater reliability

Fine-Tuning Climate Resilience in Marine Socio-Ecological Systems: The Need for Accurate Space-Time Representativeness to Identify Relevant Consequences and Responses

Climate change triggers a wide mosaic of regional and local responses, often different to the large-scale variability in magnitude and direction. Because of the psychological connections (cognitive and emotional) with the frequency, intensity and age of a climatic event, people may have the capacity to recognize key variations at lower scales, especially those from which they perceive risk. Yet, the anticipatory actions and social engagement to respond or adapt to climate change are difficult to achieve, mostly when there exists a long psychological distance to climatic phenomena. Research about climate change communication provides clues about the relevance of place-based discussion to gauge risk perception and improve response protocols, their design and prioritization. It argues that strategies and actions required to face climate risks may widely differ depending on the scale and accuracy of the local representations displayed during discussions of climate impacts. This work examines how local attributes (from climate to social) operate and control place-specific risks and priorities, by comparing coastal communities in two locations, Cabo Pulmo, Mexico and Zanzibar, Tanzania, which are subject to different climate dynamics. This paper discusses the need to identify relevant climate risks/responses at the local level and how psycho-social factors (e.g., psychological distance, collective memory, and social engagement) may operate positively for building climate resilience. We also illustrate a workflow to increase and enhance collaboration between researchers and local people by promoting dialogue, participation and narratives that rigorously consider the local knowledge

Covid-19, impactos económicos y socio-ecológicos en tres comunidades de pescadores artesanales en Yucatán

Yucatán, estado mexicano ubicado en la península del mismo nombre, cuenta con 378 kilómetros de litoral, conformado por quince puertos, albergando aproximadamente cien mil habitantes dedicados culturalmente a la pesca artesanal; la cadena productiva de la pesca artesanal de esta región consiste en la extracción, comercialización y una transformación incipiente. Ante la pandemia del Covid-19, gobierno y pobladores cerraron accesos a los puertos, limitando incluso entradas de insumos y víveres, los recursos marinos como bienes comunes representaron una fuente nutrimental importante que reforzó el vínculo cultural mar-comunidad. La economía costera sufrió afectaciones, pues su economía depende de la comercialización pesquera. El presente estudio analiza el impacto de la pandemia desde un enfoque cualitativo, abordando: Cambios derivados de la pandemia, adaptaciones socio-económicas, culturales y sanitarias, así como la presión hacia los recursos marino-costeros, todo en el marco de bienes comunes propuesto por Elinor Ostrom. Se reflexionó acerca de ¿Cómo percibe el pescador los cambios culturales, económicos y sanitarios en su actividad por la pandemia? Y su visión del futuro de la pesca artesanal. La metodología utilizada para el análisis de la información fue la Fenomenología. Las narraciones se obtuvieron mediante entrevistas telefónicas semiestructuradas durante el mes de julio 2020 aplicadas a 45 pescadores del portafolio de directorios construidos en la labor costera en Celestún, Sisal y San Felipe. Objetivo: expresar las principales afectaciones al pescador ocasionados por la pandemia, tomando como base los imaginarios de los pescadores y su implemantación de estrategias para superar la crisis. Lo que nos llevó a concluir que los principales impactos han sido los económicos por el cierre de las exportaciones, lo que demuestra una fuerte dependencia del pescador artesanal a los mercados internacionales, sin embargo, el ingenio del pescador de bajura, le ha ayudado a diseñar e implementar estrategias resilientes encontrando nuevos medios y mercados para comercializar sus bienes dando un paso hacía la economía circular y a la reactivación de la economía regional
