Sobre una tendencia del deseo femenino en el cine "mainstream". La reconstrucción de la identidad en el díptico audiovisual Gravity (2013) y El viento (1928)
Authors: Antón Sánchez Laura
Published: June 2021

En la ficción audiovisual contemporánea, las tramas de acción protagonizadas por el arquetipo de la mujer investigadora dan forma a una de las constelaciones femeninas más complejas del universo Hollywood, cuyo estudio puede ayudarnos a comprender cómo se forja la idea cultural de (llegar a) ser mujer, así como las posibles transformaciones que este modelo de identidad femenina haya podido experimentar en nuestro imaginario audiovisual. A través de este arquetipo, fortalecido en el último periodo de recesión económica, se ha construido un referente de subjetividad que pone en crisis la definición institucional de mujer. En este modelo, la feminidad solo se alcanza tras realizar un duro trayecto de iniciación durante el cual la heroína se encuentra con figuras de un discurso patriarcal que funcionan a modo de pruebas a superar para alcanzar la identidad de una nueva mujer. La autoconsciencia del relato, la metaficción y la parodia son por tanto los rasgos característicos de la narrativa audiovisual de este arquetipo moderno. El presente estudio se ha centrado en el análisis textual de Gravity (Alfonso Cuarón, 2013), pero con el fin de comprender qué lugar ocupa su propuesta en esta constelación simbólica femenina se ha utilizado un método de análisis (textual) comparado generando un diálogo con otros textos audiovisuales por los que transita esta desafiante imagen de la mujer.
Análisis del impacto de las redes sociales sobre el tráfico web de los cibermedios nativos digitales españoles
Authors: Parra Valcarce David , Onieva Mallero Charo
Published: June 2021

La apuesta de los cibermedios nativos digitales por las redes sociales como instrumentos estratégicos para incrementar el volumen de tráfico web hacia sus portales se sustenta en aspectos como la consolidación de la web semántica manual o la eclosión de los prosumidores. Este artículo se plantea como objetivo principal analizar hasta qué punto es cierto que dichas plataformas contribuyen a incrementar el número de visitantes y si el esfuerzo que realiza la industria de la información para formar parte de ellas está o no justificado. Se examina dicha cuestión a partir de la selección de una muestra significativa de diez de ellos basada en el criterio cuantitativo del número mensual de usuarios únicos que acceden a sus sitios web, empleándose para el estudio un software como SimilarWeb. Asimismo, se lleva a cabo una comparación entre el impacto de las redes sociales y el que tienen magnitudes como el tráfico directo o el uso de buscadores basados en procedimientos de posicionamiento SEO como elementos de generación de tráfico web total.
Narrativas transmedia y proximidad política en la campaña electoral de Jorge Yunda Machado, Alcaldía de Quito 2019
Authors: Enríquez Cruz María José , Gómez Navas Juan Sebastián
Published: June 2021

El estudio explora cómo se utilizó la narrativa trasnemdia para generar estrategias de proximidad en la campaña municipal de Jorge Yunda Machado a la Alcaldía de Quito 2019, y cómo éstas condicionaron la imagen del candidato, como un político «cercano y humano» permitiendo así una identificación «anti carismática» hacia la comunidad de electores.

Para ello se empleó una investigación cualitativa, empleando el análisis de contenido (denotativo y connotativo), como metodología para procesar la información obtenida de los soportes comunicacionales y entrevistas a expertos. Para el diseño del modelo de análisis, se consideró las propuestas de Canel (1999; 2008) sobre la organización y planificación de la comunicación electoral y, el aporte de Annunziata (2012), referido a la proximidad política.

Tras el análisis se concluye que la proximidad, (física y simbólica) del candidato, hizo que los electores lo percibieran como una persona común, preocupada por los problemas que afectaban a la mayoría de los ciudadanos de Quito.

Los condes de Présaras y la fundación de San Salvador de Sobrado. El intento de una parentela magnaticia por recuperar su preeminencia en Gallecia
Authors: Escudero Manzano Gonzalo J.
Published: June 2021

La sede episcopal de Santiago de Compostela fue uno de los primeros centros de la monarquía ovetense en Gallecia. Desde sus orígenes a comienzos de la novena centuria, estuvo vinculado directamente a una poderosa parentela local, los descendientes del comes Aloito. Durante varias décadas, los diversos reyes astur-leoneses promocionaron esta cátedra y se sirvieron de sus titulares para irradiar su autoridad sobre un territorio que comenzaba a integrarse en el regnum. Esta situación cambió a partir del segundo tercio del siglo X. La fundación del monasterio de Celanova por parte de otra poderosa familia del noroeste ibérico, los Gutiérrez, atrajo la atención de Ramiro II y quebró el monopolio ejercido por los obispos compostelanos. A lo largo de las siguientes páginas analizaré cuál fue la respuesta de los condes de Présaras, principales damnificados, para revertir esta situación y qué papel jugó San Salvador de Sobrado en esta nueva coyuntura.
Climate Change and Building Energy Consumption: A Review of the Impact of Weather Parameters Influenced by Climate Change on Household Heating and Cooling Demands of Buildings
Authors: Bazazzadeh Hassan , Nadolny Adam , Safaei Seyedeh Sara Hashemi
Published: June 2021

The growth of urban population as the result of economic and industrial development has changed our place of living from a prosperous place to where the resources are carelessly consumed. On the other hand, long-term climate change, i.e. global warming, has had adverse impact on our resources. Certain resources are on the verge of depletion as the consequence of climate change and inconsiderate consumption of resources, unless serious measures are implemented immediately. The building sector, whose share in the municipal energy consumption is considerably high, is a key player that may successfully solve the problem. This paper aims to study the effects of climate change on the energy consumption of buildings and analyze its magnitude to increase the awareness of how construction can reduce the overall global energy consumption. A descriptive-analytical method has been applied to analyze valid models of energy consumption according to different scenarios and to interpret the conditions underlying current and future energy consumption of buildings. The results clearly show that the energy consumption in the building sector increasingly depends on the cooling demand. With that being said, we can expect the reduction of overall energy consumption of buildings in regions with high heating demands, whereas rising the energy consumption in buildings is expected in regions with high cooling demand. To conclude, the long-term climate change (e.g. global warming) underlies the increased energy consumption for the cooling demand whose share in total energy consumption of buildings much outweighs the heating demand. Therefore, to conserve our resources, urban energy planning and management should focus on working up a proper framework of guidelines on how to mitigate the cooling loads in the energy consumption patterns of buildings.
Towards a global history of the Unidad Popular
Authors: Harmer Tanya
Published: June 2021

Our understanding of the international and transnational history of Chile during the Unidad Popular (UP) government has expanded considerably since the early 2010s. But what has new research contributed to our understanding of events in Chile and Chile’s significance in a global context? Examining the historiographical advances and questions that have driven scholarship in recent years, this article argues that international and transnational studies that focus attention on Chile and Chileans can offer new perspectives on the rise and fall of the UP. Rather than reducing international histories to an account of a select group of foreigners acting on an empty Chilean stage, these approaches foreground local actors and processes, exploring the extent to which Chileans were shaped by a multiplicity of interactions, invitations and inspirations across borders. Localising the global in this way can help us understand the reasons many within Chile conceptualised their goals, projects and actions as they did. It challenges the idea of Chilean exceptionalism. It also undermines right-wing actors’ claims to be acting solely within national frameworks by revealing their own entanglements in translational networks and intellectual imports. Suggesting that we have much still to learn, the article also highlights possible avenues for further research and reflects on the contemporary relevance of the global in Chilean political discourse today.
Scholarship on the Popular Unity in Chile since 2000. Are historians lagging behind?
Authors: Del Pozo Artigas José , Monsálvez Araneda Danny , Valdés Urrutia Mario
Published: June 2021

This article examines the questioning indicated by some historians at the beginning of the twenty-first century regarding that they would be in debt to the study of the Allende government and the Popular Unity (UP) in Chile (1970–3). Although historians have investigated the diverse issues and problems of that period in varying depth, there are topics that have not been fully addressed: for example, the relationship between socialists, communists and President Allende, and the participation of left-wing women, native people and youth in the referred historical process. However, this work addresses the contributions on the subject made mainly by Chilean authors in books and articles on UP, namely: general studies on the period, works concerning Allende and some of his close collaborators, the economic changes that affected national and international private interests, some of the forces of the Left and Right (parties and movements), popular social sectors, the state coup, the military, culture and the press. A novel aspect in a significant number of these works is the use of interviews with witnesses who played a significant role in, or lived through, the UP period.

Authors: Iqbal Muzaffar , Ahmad Naveed , Waqas Muhammad , Abrar Maira
Published: June 2021

Goal: COVID-19 has a drastic effect on world economic progress and different industries. As the main contributor to countries' economies, the construction industry faced multiple challenges due to pandemics. Therefore, it's essential to identify the impact of COVID-19 on the construction sector and develop safety practices in construction processes. This study proposed necessary construction practices and a crisis management framework needs to adopt in the COVID-19 scenario.

Design/Methodology/Approach: At the first stage, data on negative impacts on the construction industry due to the pandemic was compiled. Then, experts were invited to propose emerging safety measures and practices to improve the safety of construction employees. Lastly, crises management framework was proposed, which provides an increased capability of taking measures during and after the COVID-19 pandemic.

Results: Results showed that COVID-19 has an adverse effect on the construction sector of different developed and developing countries. Therefore, there is a need to incorporate proposed safety practices at construction sites and apply crises management framework to increase construction productivity during the pandemic.

Limitations of the investigation: This study has certain limitations for instance the availability of data regarding construction sector was limited especially about small countries whose economies are not fully documented and construction sector is not regulated. The evaluation and assessment made in this study were generally subjective and it cannot be generalized to other sectors. This work could insist on enhancing the work plan for the future to encounter the uncertain circumstances for construction industry.

Practical implications: This work will be useful for construction managers and policy makers to cope with COVID-19 and to adopt necessary safety measure for construction sector. This work also be helpful for other industry stakeholders to pinpoint risk management efforts that could be suitable for their firms. industrialists may use these research efforts to sort out the problem areas and propose an appropriate framework for industry.

Originality/value: This study will provide guidelines to construction professionals for taking necessary measures to cope with COVID-19 and to apply a crises management framework.

Asia Pacific is renowned as a travelling hot spot amongst both domestic and international tourists. With Malaysia as the focal point, and based on the foundation of Stimulus-Organism-Response (SOR), this study aims to explore different routes undertaken by tourists towards both satisfaction and loyalty concerning the Malaysian tourism industry, following the impacts of service innovation and destination image. A self-administrated survey was conducted across 322 tourists. The significance of the hypothesized relationships was further tested by employing the AMOS’s structural modelling approach. Obtained results demonstrate that service innovation as a direct antecedent to destination loyalty, destination image and tourist satisfaction. Destination image also has a direct influence on destination loyalty. The mediating roles of destination image and tourist satisfaction between service innovation and destination loyalty were also established. The findings determined service delivery and innovation as more effective marketing tools to tourism practitioners for building brand reputation and tourists’ loyalty. Service innovation remains absolutely crucial in the competitive tourism marketplace to build and sustain tourist satisfaction and destination loyalty.

Authors: Husna Aftina Nurul , Akmal Nur
Published: June 2021

This article reports on the effort to test psychometric properties of the revised version of Skala Karakter Wirausaha (SK-Wira). The research aims to clarify the scale’s internal structure by examining its construct validity. Construct validity is proven through confirming the internal structure and associating the scale with relevant variables. Revised version of SK-Wira and other measures were administered to university students in Magelang and Makassar (N = 598). After completing CFA, Study 1 confirmed that SK-Wira can be used as both multidimensional scale (model 1) to measure general entrepreneurial character, and unidimensional scales (model 2) to measure specific domains separately. Both models showed good fit. In Study 2, general and specific domains of entrepreneurial character were correlated with hope of success, fear of failure, openness to experience, neuroticism, entrepreneurial intention, and entrepreneurial self-efficacy. The results accepted all proposed hypotheses. In conclusion, SK-Wira is a valid instrument to measure entrepreneurial character for psychology of entrepreneurship research.

Authors: Moura Delmo Alves de , Bonadio Victor Carneiro
Published: June 2021

Air transport accounts for a significant portion of all wealth production in the world. In the case of Brazil, although the air transport industry is undergoing profound changes because of the economic crisis, there is enormous potential for this market to resume growth, especially when compared to the number of passengers/inhabitant of already consolidated markets, such as the United States. However, to grow in this market, airlines need to be prepared to adapt to new dynamics and overcome the effects of the economy on the industry. This paper presents a case study of an airline that in the crisis period lost its market leadership and chose to restructure the business-to-business (B2B) sales department to achieve better results in its Business Process Management (BPM). It seeks to identify which factors led the company to lose this leadership from the perspective of its customers and propose a way to review internal processes, eliminating waste, so that the company can resume its position in the market. It has been applied lean service-focused concepts to raise possible causes, identifying and optimized internal sales department flows to create a more appropriate customer value proposition, and correcting for each type of waste mapped. The objective of this case study was to apply the concepts related to the Value Stream Map tool to reduce activities that do not add value, in a service area, of a large airline. The objective was to improve the company's Business Process Management, aiming at a lean, effective and efficient process, improving the organization's performance and competitiveness.

Authors: Achcar Jorge alberto , Godoy Daniel Marcos
Published: June 2021

The evaluation of the service quality standard of a telecommunication company using statistical process control (SPC) methods is the main goal of this paper. The study used a dataset collected from January 2018 to November 2019 associated with monthly and weekly customer complaint counts due to the technical services provided by the company. Multiple linear regression models with the count data transformed to a logarithmic scale and Poisson regression models with the original count data detected some significant factors affecting the weekly/monthly complaint counts. In addition, forecasts of future complaint counts based on the statistical models could be of interest for the company to plan the number of technicians in different sectors at different times of the year leading to improvements in the service provided by the telephone company.

The consumption of natural products has become increasingly intense in recent years, arousing the interest of several new entrepreneurs and companies that already operate in the market, whether with the same type of business or not, as within this area other issues are inserted that are of collective interest. The study of consumer behavior comprises the actions of purchase, use and disposal of the purchased product and, also, the processes and decisions that occur before and after these actions. Therefore, the objective of this article is to identify which and how certain factors may influence the behavior of consumers of natural products in their purchase decision process. The methodology used was the bibliographic research analyzing several and relevant references on the theme. The results of this research show that in order to be successful in the field of natural products, it is essential to improve the relationship between organization and consumer and how important it is to know all the aspects that involve their decision and behavior, since the consumer buying behavior of natural products it is not only based on your personality, but also on personal, cultural, emotional, psychological factors and also on environmental issues. The survey also details the importance of consuming natural products for society and the environment, providing a healthier environment for those involved. Thus, the work emphasizes the relevance of knowledge and investment in marketing and research that can help companies to dedicate themselves more to attract consumers not only in their area of activity, but also consumers of other products and / or services, winning and retaining new customers.

Published: June 2021

The aim of this study is the KEYS questionnaire cross-cultural adaptation into the Lithuanian language. This study was designed to translate and perform cultural adaptation as well as test the reliability of the Lithuanian version of the KEYS questionnaire. Guidelines for the questionnaire translation and adaptation procedure according to international recommendations based on scientific literature were followed in order to establish the cultural equivalence to the original English version of the KEYS questionnaire. In the cross-cultural adaptation stage, due to the Lithuanian cultural context, several discrepancies between the semantic and conceptual equivalence of the items were modified. In total, 155 respondents participated in the pilot study of the Lithuanian KEYS version. As to reliability of the Lithuanian KEYS version, psychometric properties were tested, Cronbach’s alpha coefficient was used to assess the internal consistency. Mostly all scales and items demonstrated good internal consistency. The Lithuanian KEYS version was a well-accepted, reliable tool for evaluating and assessing individual work environment perceptions that influence the creativity of organizations among the Lithuanian speaking population. We conclude that the Lithuanian version of the KEYS questionnaire was successfully translated and adapted for application to Lithuanian-speaking respondents and it is ready for the validation study. Such a research is the first in the Baltic region.

Authors: Ceciliano Paulo Henrique , Da Costa Vieira Paulo Roberto , Magalhães da Silva Antônio Carlos
Published: June 2021

The concept of corporate social responsibility (CSR) plays an important role in corporate marketing and is understood as a strategic variable, because if managed properly, it can increase the corporation's market share. This study investigates the various causal relationships between corporate social responsibility, corporate brand credibility (CBC), corporate reputation (CR) and corporate brand equity (CBE). Data were collected through a survey with a self-administered structured questionnaire, with five response options scored on a Likert scale. The sample included 310 consumers who expressed their opinions on a large Brazilian oil and gas company. The data were treated through structural equation modeling with partial least squares. The results showed that CSR has direct and indirect effects on CBE. Mixed methods are worthwhile to those who are working on a doctorate research work. Moreover, it will be helpful to develop knowledge through this method that can be beneficial to academia and Practitioners.

Sex steroids-induced neurogenesis in adult brain: a better look at mechanisms and mediators
Authors: Abotalebi Hamideh , Ebrahimi Babak , Shahriyari Raziyeh , Shafieian Reyhaneh
Published: June 2021

Adult neurogenesis is the production of new nerve cells in the adult brain. Neurogenesis is a clear example of the neuroplasticity phenomenon which can be observed in most of mammalian species, including human beings. This phenomenon occurs, at least, in two regions of the brain: the subgranular zone of the dentate gyrus in hippocampus and the ventricular zone of lateral ventricles. Numerous studies have investigated the relationship between sex steroid hormones and neurogenesis of adult brain; of which, mostly concentrated on the role of estradiol. It has been shown that estrogen plays a significant role in this process through both classic and non-classic mechanisms, including a variety of different growth factors. Therefore, the objective of this review is to investigate the role of female sex steroids with an emphasis on estradiol and also its potential implications for regulating the neurogenesis in the adult brain.
Differential positive sequence power angle-based microgrid feeder protection
Authors: Ansari Salauddin , Gupta Om Hari
Published: June 2021

Integration of distribution generation (DG) makes the growth of the microgrid protection scheme very challenging issues. Researchers from all over the world continuously are doing hard work for developing the microgrid protection schemes. A differential positive sequence power angle (DPSPA) based microgrid protection scheme is proposed in this paper using positive sequence (PS) components of voltages and currents. The DPSPA for the feeder is calculated considering both ends of voltage and current signal information, when it is more than threshold, internal fault is reported otherwise, it is an external fault. Taking into consideration the varying operational modes of the microgrid, variations in DG penetration, and variations in fault variables namely fault types, and fault locations, the proposed protection scheme is verified on a modified IEEE-13 bus feeder. Moreover, to test the robustness and efficacy of the suggested scheme, various non-faulty events including induction motor starting, non-linear loading, load switching, capacitor switching, and section cutoff have been conducted. The proposed scheme is also verified for external faults and it is found that it continues to be stable for the external faults. The findings exhibit this proposed scheme, which is based on DPSPA, can successfully protect the microgrid under changing operating conditions.
Transference-Focused Psychotherapy for Pathological Narcissism and Narcissistic Personality Disorder (TFP-N)
Authors: Diamond Diana , Yeomans Frank , Keefe John R.
Published: June 2021

In this article, we provide an overview of transference-focused psychotherapy for patients with pathological narcissism and narcissistic personality disorder (TFP-N). In TFP-N we have modified and refined the tactics and techniques of TFP, an evidence-based treatment for borderline personality disorder, to meet the specific challenges of working with patients with narcissistic personality pathology whose retreat from reality into an illusory grandiosity makes them particularly difficult to engage in treatment. We first describe a model of narcissistic pathology based on considerations of psychological structure stemming from object relations theory. This model provides a unifying understanding of the core structure of narcissistic pathology, the pathological grandiose self, that underlies the impairments in self and interpersonal functioning of those with narcissistic pathology across the levels of personality organization (from high functioning to borderline to malignant). We then delineate the clinical process of working with patients with pathological narcissism and narcissistic personality disorder. Starting with the assessment process, using a detailed clinical example, we guide the reader through the progression of TFP-N as it helps the patient move from the distorted, unintegrated sense of self underlying the narcissistic presentation to the more integrated, realistic sense of self that characterizes healthier personality functioning. In TFP-N the focus on the disturbed interpersonal patterns of relating in the here and now of the therapeutic interaction is the vehicle to diminish grandiosity and improve relatedness, thereby effecting enduring changes in mental representation and real-world functioning.
Good Psychiatric Management and Transference-Focused Psychotherapy for Borderline Personality Disorder: A Spectrum of Psychodynamically Informed Treatments
Authors: McCommon Benjamin , Hersh Richard
Published: June 2021

Good psychiatric management for borderline personality disorder (GPM) and transference-focused psychotherapy (TFP) are evidence-supported treatments that may be used in a complementary, flexible manner to provide a spectrum of psychodynamically informed care. In this article, we provide overviews of TFP and GPM, describing GPM's eclectic approach that includes psychodynamically informed supportive psychotherapy, case management, and medication management, informed by a model of hypersensitivity to rejection, comparing it with TFP's focus on identity integration and modification of standard psychodynamic techniques for use in treating patients with borderline personality disorder. We outline convergences and divergences between TFP and GPM in assessment, establishment of treatment goals and a treatment agreement, family involvement, and moment-to-moment psychotherapeutic interventions. The options for integration of TFP and GPM theoretical principles, as well as for models of treatment sequencing, are explored. Clinical vignettes are provided that illustrate sequential uses of GPM and TFP as part of psychodynamically informed long-term clinical management.
Deep impact of superficial skin inking: acoustic analysis of underlying tissue
Authors: Carlson Craig S. , Postema Michiel
Published: June 2021

Background: Skin tattoos are a common decoration, but profound scientific study whether the presence of a skin tattoo alters the acoustic response from superficial tissue, and therefore from underlying tissue, was previously lacking. Any image aberrations caused by tattoo presence may have been thought negligible, yet empirically found artifacts in brightness-mode images of tattooed skin suggest otherwise. This study investigated the nature of these artifacts theoretically and experimentally in extremely simplified cases of perfectly flat and homogenous layered media and in tattooed pork.

Methods: Theory was derived for computing the acoustic response from horizontally and vertically layered media containing a thin inked layer. Experiments were performed in vitro. Artificial and pork skin were tattooed, attached to phantom material, and sonicated with a 13–6-MHz probe. The speed of sound of these materials was determined, and the perceived refraction angles was measured.

Results: The measured speeds of sound of tattooed materials were higher than those of their uninked counterparts. The presence of tattoo ink was found to have increased the linear acoustic attenuation by 1 dB/cm. This value is negligible for typical tattoos of only few millimeters. The perceived critical refraction angles of adjacent materials could be detected, and their corresponding speeds of sound were quantified. These coincided with values derived from theory.

Conclusion: The ratio of speeds of sound of adjacent materials was shown to create distinct highlights in brightness-mode images. The artifacts observed in in vitro and in vivo brightness-mode scans were explained from near-vertical transitions between areas of different sound speed. This is the first study correlating so-called critical refraction highlighting with speed-of-sound information. In addition, it was found that phantom material is a room-temperature acoustic alternative for experiments on live human skin. In summary, the presence of superficial tattoos has a small but quantifiable effect on the acoustic response from deeper tissues.
Redemption Song
Authors: Williams James S.
Published: June 2021

This article explores how Steve McQueen’s acclaimed 2020 pentalogy Small Axe (BBC) appears paradoxically to swerve away from Black British history in the very act of retrieving it. By examining key moments in Mangrove, Red, White and Blue, and Alex Wheatley, it argues that the constant tension between a push toward history and the pull of the aesthetic is the result of McQueen’s reformulation of “racial uplift” aesthetics that privileges exceptional acts over collective experience. Yet in striking contrast to his poetic license with history, McQueen presents Black masculinity and male self-expression within standard social and sexual norms. There are, however, more experimental, stylized moments in Small Axe where the historical and the aesthetic come together, notably in the highly physical dancing sequences of Lovers Rock. While not without limitations, such scenes reveal fresh, liberatory forms of Black space and time, and forge transformative and redemptive moments of Black reality.
Language, Nation, Race: Linguistic Reform in Meiji Japan (1868–1912)
Authors: Ueda Atsuko
Published: June 2021

Language, Nation, Race explores the various language reforms at the onset of Japanese modernity, a time when a “national language” (kokugo) was produced to standardize Japanese. Faced with the threat of Western colonialism, Meiji intellectuals proposed various reforms to standardize the Japanese language in order to quickly educate the illiterate masses. This book liberates these language reforms from the predetermined category of the “nation,” for such a notion had yet to exist as a clear telos to which the reforms aspired. Atsuko Ueda draws on, while critically intervening in, the vast scholarship of language reform that engaged with numerous works of postcolonial and cultural studies. She examines the first two decades of the Meiji period, with specific focus on the issue of race, contending that no analysis of imperialism or nationalism is possible without it.

Objective

Patients with craniopharyngioma (CP) frequently suffer from morbid obesity. Endocannabinoids (ECs) are involved in weight gain and rewarding behavior but have not been investigated in this context.

Design

Cross-sectional single-center study.

Methods

Eighteen patients with CP and 16 age- and sex-matched controls were included. Differences in endocannabinoids (2-arachidonoylglycerol (2-AG) and N-arachidonoylethanolamine (AEA)) and endocannabinoid-like molecules (oleoyl ethanolamide (OEA), palmitoylethanolamide (PEA), and arachidonic acid (AA) were measured at baseline and following endurance exercise. We further explored ECs-dynamics in relation to markers of HPA-axis activity (ACTH, cortisol, copeptin) and hypothalamic damage.

Results

Under resting conditions, independent of differences in BMI, 2-AG levels were more than twice as high in CP patients compared to controls. In contrast, 2-AG and OEA level increased in response to exercise in controls but not in CP patients, while AEA levels decreased in controls. As expected, exercise increased ACTH and copeptin levels in controls only. In a mixed model analysis across time and group, HPA measures did not provide additional information for explaining differences in 2-AG levels. However, AEA levels were negatively influenced by ACTH and copeptin levels, while OEA levels were negatively predicted by copeptin levels only. There were no significant differences in endocannabinoids depending on hypothalamic involvement.

Conclusion

Patients with CP show signs of a dysregulated endocannabinoid system under resting conditions as well as following exercise in comparison to healthy controls. Increased 2-AG levels under resting conditions and the missing response to physical activity could contribute to the metabolic phenotype of CP patients.

Duodenopancreatic neuroendocrine tumors (DPNETs) aggressiveness is heterogeneous. Tumor grade and extension are commonly used for prognostic determination. Yet, grade classes are empirically defined, with regular updates changing the definition of classes. Genomic screening may provide more objective classes and reflect tumor biology. The aim of this study was to provide a transcriptome classification of DPNETs. We included 66 DPNETs, covering the entire clinical spectrum of the disease in terms of secretion, grade, and stage. Three distinct molecular groups were identified, associated with distinct outcomes (log-rank P < 0.01): (i) better-outcome DPNETs with pancreatic beta-cell signature. This group was mainly composed of well-differentiated, grade 1 insulinomas; (ii) poor-outcome DPNETs with pancreatic alpha-cell and hepatic signature. This group included all neuroendocrine carcinomas and grade 3 DPNETs, but also some grade 1 and grade 2 DPNETs and (iii) intermediate-outcome DPNETs with pancreatic exocrine and progenitor signature. This group included grade 1 and grade 2 DPNETs, with some insulinomas. Fibrinogen gene FGA expression was one of the topmost expressed liver genes. FGA expression was associated with disease-free survival (HR = 1.13, P = 0.005) and could be validated on two independent cohorts. This original pathophysiologic insight provides new prognostic classification perspectives.
Redes sociales, agenda noticiosa y línea editorial durante hechos violentos de las protestas de 2017 en Venezuela
Authors: Flores Irama

El estudio giró en torno a dar respuestas reflexivas a las siguientes preguntas ¿En qué medida los temas noticiosos se retoman o no en la agenda noticiosa desde el punto de vista del periodismo durante las protestas de 2017 en Venezuela? ¿Qué tipo de géneros periodísticos utilizaron los medios para tratar los hechos difundidos en primera instancia por las redes sociales? y ¿Qué papel desempeñó el periodismo en el resguardo de la dignidad humana y la forma en que se divulgaron los hechos catalogados como violentos y con víctimas fatales? A los diarios el Universal y El Nacional, en su versión digital, se les aplicó fichas de precisión en las noticias relacionadas a 7 hechos con víctimas fatales de las protestas. Entre las conclusiones resaltan que en algunas informaciones divulgadas por estos periódicos, se citaron algunos tuits, colgaron fotos y videos que habían circulado en las redes; además  en algunos de los casos estudiados, estos medios incurrieron en difundir videos y fotografías de los hechos, que reproducían el momento en el cual las víctimas fallecían; cumpliendo una agenda noticiosa sensacionalista, comercial y de irrespeto.
Fotografía y comunicación: un espejo, una imagen, un ojo
Authors: Múnera Beatriz
Published: June 2021

La humanidad ha estado mediada por cambios de paradigmas que han provocado nuevos caminos, tanto en la comunicación como en la percepción individual y colectiva, o en las maneras de narrar para pensar y contar la sociedad.

Se modifica nuestra actitud ante perturbaciones tan rotundas como la que ahora vivimos con la pandemia provocada por la covid-19. Esta situación anómala entraña metamorfosis en la mentalidad de la época, de los valores que hasta ahora han formado una visión particular de la realidad.

Las fotografías, como documento social que son, tienen su propia narrativa comunicativa y son contribuciones a la historia y a la memoria (Múnera y Chaves, 2019). Una fotografía es siempre un recuerdo, una remembranza y, como ella, es frágil, se extravía, se desvanece, se pierde.

Hoy las imágenes nos reclaman una interpretación para comprender lo que nos narran; de ahí su gran poder comunicativo y su importancia para construir la realidad. Hemos hecho imágenes para testificar los hechos y para evocar las ausencias. ¿Pero qué ocupaba el lugar de la fotografía antes que ella? Siempre se ha dicho que el grabado, la pintura, el dibujo, pero una respuesta también podría ser la memoria, en la que se nos puede presentar como un espejo, como una imagen, como un ojo.

Esta reflexión alrededor de la fotografía en la docencia y su lugar en medio del confinamiento por la pandemia surge como una preocupación frente a su papel para la gestión de la vida personal y social, y sobre cómo va a significar los hechos.
Effects of loblolly pine extract, primary and quaternary alkyl ammonium chlorides combined with burgundy oil from eastern red cedar against subterranean termites and wood-decay fungi

Burgundy oil (BO) from Eastern red cedar provides resistance against termites and wood-decay fungi and is enhanced when combined with an amylose inclusion complex (AIC) containing hexadecylammonium chloride (HAC). Indirect evidence also indicated that a methanol Loblolly pine extract (LPE) was inhibitory against termites. This study compared the effects of HAC and didecyldimethylammonium chloride (DDAC) combined with LPE and BO on termites and wood-decay fungi. Southern pine was treated by vacuum/pressure impregnation and resistance evaluated after exposure to termites and decay fungi. The combination of BO and either HAC/AIC or DDAC/AIC reduced wood mass losses by termites, increased termite mortality, and inhibited all wood-decay fungi. The HAC/AIC and DDAC/AIC resulted in equivalent mass losses by termites and termite mortalities. The DDAC was slightly more inhibitory than the HAC against wood-decay fungi. Given the slight advantage of DDAC over HAC and because DDAC is currently used to preserve wood, DDAC might be preferred over HAC. The LPE had a very minor effect on mass loss by termites, termite mortality, and only a slight inhibitory effect on G. trabeum and T. versicolor, while R. placenta and I. lacteus were unaffected. Higher concentrations of DDAC and/or LPE might improve protection against termites and wood-decay fungi.

Lignocelluloses are comprised of cellulose, hemicellulose, and lignins, which constitute plant biomass. Since peroxidases can degrade lignins, the authors examined peroxidase Tfu-1649, which is secreted from the thermophilic actinomycetes, Thermobifida fusca BCRC 19214. After cultivating for 48 h, the culture broth accumulated 43.66 U/mL of peroxidase activity. The treatment of four types of lignocellulolytic byproducts, i.e., bagasse, corncob, pin sawdust, and Zizania latifolia Turcz husk, with Tfu-1649 alone increased the total phenolic compounds, with limited reducing sugars, but treatment with xylanase, Tfu-11, and peroxidase Tfu-1649 showed synergistic effects. Hence, the co-operative degradation of lignocelluloses by both peroxidase and xylanase could contribute to biomass decomposition and further applications in the agricultural and environmental industries.
