Timidez, género y movilización social
Authors: Castillo Rocío A.
Published: February 2020

La timidez es un estado emocional poco trabajado por las ciencias sociales, no obstante que es una emoción muy presente en la vida de las mujeres. Este artículo analiza la timidez desde una perspectiva de género para mostrar que es un estado emocional fundamental en la construcción de relaciones de poder generizadas, al tiempo que, con base en un estudio de corte etnográfico con dos organizaciones de base migrante en Texas, plantea la importancia de la subversión emocional, es decir, de las transformaciones subjetivas (en este caso de la timidez) como fundamentales en los procesos de movilización social de mujeres en contextos de alto riesgo. Así, incita a futuras investigaciones académicas a mirar no solo aquellos recursos objetivos que motivan a las mujeres a la movilización, sino sobre todo al ámbito de lo subjetivo, pues es ese el lugar desde donde ellas se reconstruyen a sí mismas como mujeres activistas.

Posfeminismo / Genealogía, geografía y contornos de un concepto
Authors: Giraldo Isis
Published: February 2020

El término posfeminismo ha tenido usos múltiples y contradictorios en el circuito académico y los medios angloamericanos. A pesar de que el fenómeno que denota se ha expandido más allá de las fronteras del contexto social, cultural, económico, político y geográfico en el cual se origina, los trabajos que se ocupan de él en el mundo hispanoparlante son virtualmente inexistentes. Este artículo busca colmar este vacío. Expongo los contornos del posfeminismo como concepto analítico e intento demostrar que el potencial teórico del término solo se pone de manifiesto si se entiende como un régimen de subjetividad femenina de proyección global intrínsecamente conectado con el capitalismo y el ethos neoliberal, que incorpora feminidad espectacular e hipersexualización, pone “la colonialidad del género” en acción y, en vez de desestabilizarlo, refuerza el patriarcado.
El género sin sexo ni derechos: la Ley de Identidad de Género en Bolivia
Authors: Absi Pascale
Published: February 2020

En mayo de 2016, la Asamblea legislativa plurinacional de Bolivia adoptó la llamada Ley de Identidad de Género. Desde entonces, las personas pueden rectificar su dato de sexo y su nombre en el registro civil mediante un simple y rápido procedimiento administrativo con base en una solicitud declarativa. Un poco más de un año después, en noviembre de 2017, un fallo del Tribunal Constitucional anula el artículo 11 que otorgaba a la transidentidad los derechos del sexo rectificado. Al presentar las condiciones de la adopción de la ley, y de su revocación parcial, este artículo se propone mostrar que dicho vuelco tiene que ver con una interpretación particular de las categorías sexo y género que desborda el marco de la legislación boliviana.

Prevalencia de Burnout en auditores gubernamentales de México, perspectiva de género
Authors: Moreno Juan Carlos , Trujillo Flores Mara Maricela , Lámbarry Vilchis Fernando
Published: February 2020

Los auditores gubernamentales en México enfrentan agotadoras cargas de trabajo que más allá del cansancio físico y emocional, los predispone a ocasionarles problemas psicosociales como es el Síndrome de Quemarse por el Trabajo (SQT-Burnout), entre otros. No obstante, para esta profesión, el burnout no ha sido estudiado con profundidad como lo ha sido para algunas otras (especialmente aquellas que pertenecen al sector educativo y de la salud) y aún menos desde la perspectiva diferenciada por la variable género. El estudio cuantitativo con carácter no generalizable implicó aplicar el Maslach Burnout Inventory-General Survey (MBI-GS) a 557 auditores del ámbito federal y subnacional, instrumento basado en el modelo tridimensional de Maslach y Jackson que considera agotamiento emocional, sentimientos de cinismo y desapego con el trabajo y sensación de ineficacia profesional y falta de logro, la literatura especializada ha demostrado que no se trata únicamente de un fenómeno contingente. Para contrastar la hipótesis planteada Ho: las distribuciones de burnout entre hombres y mujeres son iguales, a través del método U de Mann-Whitney. Se concluye que en los auditores gubernamentales es mayor el burnout en las mujeres que en los hombres. 
Efectos de la responsabilidad social empresarial sobre la identificación organizacional de los empleados: Autenticidad o falacia
Authors: Contreras-Pacheco Orlando Enrique , Talero-Sarmiento Leonardo Hernán , Camacho-Pinto Julio Cesar
Published: February 2020

El greenwashing implica el predominio del uso falaz de la responsabilidad social empresarial (RSE simbólica) sobre la práctica auténtica de la misma (RSE sustancial). Su definición representa una tensión conceptual, susceptible de ser estudiada a la luz de su impacto sobre la identificación de los individuos como miembros de una organización. El presente trabajo estudia dicho impacto por medio de una investigación transversal aplicada sobre doscientos veinte empleados profesionales en Colombia y analizada a través del modelamiento con ecuaciones estructurales. Los resultados obtenidos dan cuenta del carácter asociativo de la RSE sustancial sobre la identificación organizacional de los empleados, así como de la ausencia de vínculo entre la RSE simbólica sobre esta misma actitud. Sin embargo, también encuentra una correlación directa entre la RSE simbólica y la RSE sustancial que podría suponer una aceptación tácita del greenwashing como una práctica válida. A nivel teórico, se contribuye en la medida en que se prueba por primera vez un modelo conceptual usando constructos de reciente incorporación a la literatura. Asimismo, a nivel práctico, se sugiere que la toma de decisiones sobre aspectos relacionados con la RSE están en continuo escrutinio por parte de los empleados de acuerdo a la autenticidad de su adopción y con posibles consecuencias sobre sus comportamientos.

Authors: Ahuja Sánchez Leonor , Yépez Ríos Norma Beatriz , Pedroza Zapata Álvaro Rafael
Published: February 2020

Este trabajo explora la relación entre Gestión de la Calidad Total (GCT) y Gestión de la Tecnología e I+D (GT/I+D) para responder a dos preguntas centrales: si la GCT favorece o limita el desarrollo de la capacidad de innovación tecnológica en las organizaciones mexicanas, y si la GCT puede servir de soporte a la GT/I+D. Se evidencia la significación estadística del modelo teórico que relaciona la GCT con la GT/I+D mediante el análisis de correlaciones bivariadas, ecuaciones estructurales y regresión múltiple a partir de la encuesta realizada a 125 empresas manufactureras que operan en México. Los resultados indican que existe una correlación significativa y positiva entre la GCT y la GT/I+D. Entre los elementos facilitadores destacan el alineamiento estratégico que amalgama calidad e innovación tecnológica, el enfoque al cliente, la gestión por procesos y el fundamento que ofrecen los procesos de gestión del talento.

Published: February 2020

Se analizó la relación entre desarrollo financiero y desigualdad del ingreso empleando una base de datos que comprende 13 países de América Latina, en un período que abarca del año 1990 al año 2015. La variable principal es el desarrollo financiero, la cual es medida través de la proporción crédito a PIB. Por otro lado, para medir la desigualdad del ingreso se empleó el índice de Gini. Para realizar el análisis se emplearon los siguientes métodos econométricos:  efectos fijos, mínimos cuadrados generalizados estimados y el método de momentos generalizados junto con mínimos cuadrados generalizados estimados. Además, se utilizaron las siguientes variables de control:  PIB per cápita, gastos del gobierno con respecto al PIB, apertura comercial, la tasa de inflación y la población. Se encontró que el desarrollo del sistema financiero incrementa la desigualdad del ingreso. Dichos resultados se validaron empleando diferentes especificaciones econométricas.
Electronic commerce contribution to the SME performance in manufacturing firms: A structural equation model
Authors: Alderete María Verónica
Published: February 2020

The role Information and Communication Technologies (ICT) play in achieving a better organizational performance still needs further analysis among small and medium sized enterprises (SME) from developing countries. This study aims to extend the empirical literature on the relationship between ICT, electronic commerce and SME performance in developing countries. To achieve this goal, we employ a sample of 87 manufacturing firms from the city of Bahía Blanca, Argentina in the year 2015. By estimating a structural equation model, we obtain that electronic commerce adoption has a positive and significant influence on SME sales which is reinforced by the level of ICT use. Other organizational factors such as firm size and public programs explain performance, but are not significant predictors of the electronic commerce adoption. 
Banca ética cooperativa: un análisis de las innovadoras operaciones de amortización de JAK Medlemsbank
Authors: Valls Martínez María del Carmen , Ramírez Orellana Alicia , Abad Segura Emilio
Published: February 2020

Este trabajo estudia, desde un punto de vista financiero, el funcionamiento del sistema de depósitos y de créditos en la cooperativa bancaria ética sueca JAK, calculando cuál es el coste efectivo real de una operación de préstamo. Los resultados ponen de manifiesto que el original modelo de esta autodenominada “banca libre de interés” sí supone en realidad para el prestatario un coste efectivo real en sus préstamos. Además, se muestra cómo, en circunstancias normales, este coste es muy superior al promedio del coste ofertado por los bancos tradicionales. Ello es debido a que JAK exige un depósito no remunerado de cuantía superior, debido a la aplicación de un coeficiente reductor, e igual plazo al del préstamo concedido. En consecuencia, considerando solamente criterios económicos personales, este tipo de banca no resulta atractiva. No obstante, si se tienen en cuenta los beneficios sociales, así como la posibilidad de ceder derechos de préstamo (puntos de ahorro positivos) a otros miembros, entonces su utilidad es considerable desde un punto de vista económico y social.
A study of food retailing: How does consumer price sensitivity vary across food categories and retailer types in Mexico?
Authors: Díaz Eduardo R. , Ivanic Aarti S. , Durazo Watanabe Eduardo
Published: February 2020

The cost of food in Mexico has increased over several decades while modern retailers face intense rivalry. Currently, consumers have several choices for buying food, which prompts retail managers to implement pricing strategies designed to differentiate from competitors and attract more customers. The problem is that several retailers seem to be using the same approach without a clear understanding of consumer price sensitivity, the effect of non-price promotions, and the variations across retail formats. This research will address these issues by analyzing scanner sales data and mystery shopper price reports to calculate price sensitivity across six food categories sold in four retail chains. Results indicate that product demand, in most food categories, is sensitive to price changes at big-box retail competitors and not traditional supermarket retailers. Additionally, results indicate that the six food categories in the study are sensitive to feature advertising. Retail managers can use these findings to help define their value propositions, focus their pricing strategies, and inform their marketing communications strategy.
The Discrete Particle Swarm Optimization Algorithms for Permutation Flowshop Scheduling Problem
Authors: Amallynda Ikhlasul
Published: February 2020

In this paper, two types of discrete particle swarm optimization (DPSO) algorithms are presented to solve the Permutation Flow Shop Scheduling Problem (PFSP). We used criteria to minimize total earliness and total tardiness. The main contribution of this study was that a new position update method is developed based on the discrete domain because PFSP is represented as discrete job permutations. In addition, this article also comes with a simple case study to ensure that both the proposed algorithm can solve the problem well in a short computational time. Hybrid Discrete Particle Swarm Optimization (HDPSO) has a better performance than the Modified Particle Swarm Optimization (MPSO). The HDPSO produced the optimal solution. However, it has a slightly longer computation time. Besides, the population size and maximum iteration impact the quality of solutions produced by HDPSO and MPSO algorithms.

Published: February 2020

In practice, the policy of delaying payment periods is prevalent between players in a supply chain system. Generally, payments are made at the end of the permitted period. Supply chain management is one of the keys to corporate sustainability that the activities impact the environment.  This paper aims to develop an integrated green supply chain model with a permissible delay in payment consideration. In this research, the author develops a mathematical model to find the effect of delay in payment on emissions costs without ignoring the economic performance of a supply chain. The author develops four different scenario models. Furthermore, numerical experiments and sensitivity analysis tests were conducted. The study results show that delay in payment is integrated into the supply chain system, which has a positive impact on reducing supply chain emissions costs.

Rosmarinic acid (RA) is a polyphenolic compound recently associated to a neuroprotective potential. Nevertheless, besides the RA poor bioavailability and availability in the central nervous system (CNS) some alternatives to RA delivery, protection, and release been investigated. Recently, our research group optimized chitosan-coated nanoemulsions for RA nasal administration and demonstrated the glioprotective effect against LPS-induced damage in astrocytes. In this context, this study aimed to validate a fast, simplified and stability-indicating UFLC method previously reported by our research group for RA determination in Wistar rat’s plasma and brain, to be employed in further in vivo studies, since the nasal route for RA are not completely understood. The method was validated in terms of specificity, linearity, matrix effect, stability, precision, accuracy and extraction recovery for rat plasma and brain, according to the official guidelines. The method was sensitive, linear (0.1 - 10 µg.mL−1), precise and accurate, and showed RA recovery higher than 85% in plasma and brain. Overall results demonstrated that method was successfully validated for determination of RA in rat plasma and brain matrices with high sensibility and with high recovery using simple extraction processes.

Published: February 2020

In recent years, both corporate governance and performance management have been subjected to considerable changes. In this dynamic context, it is interesting to study the evolution of the relationship between performance and governance. Does governance still affect performance? The purpose of this paper is to verify the presence and intensity (extent) of the relationship between corporate governance and performance in Italian listed companies by using both accounting and non-accounting performance measures. The purpose of this paper is to investigate the effects of prior firm performance on board composition and governance structure of some companies listed on the Italian stock exchange, analysing how a governance approach influences the performance of sample companies. For the research the methodology used is quantitative and we used regression analysis on a sample of 23 Italian listed companies: mechanical companies and public utilities to find that the company's performance was positively related to the size of the board. The empirical analysis conducted allowed us to verify the hypothesis according to which the increase in Corporate Governance Best Practices influences company performance. However, the results we have received do not allow us to arrive at completely unequivocal interpretations. The results showed we have received do not allow us to arrive at completely unequivocal interpretations; the main limit is the sample size used in this study was relatively small.

Published: February 2020

Abstract: In this paper, I will explore the use of fiction films as a teaching methods in classes of social anthropology with regional interest. I will compare the use of different films from the Black Sea region as way to 1. familiarise my students with the historical dis/continuities and presuppositions which contribute to the formation of the ‘region’, 2.bring them in contact with the methods of doing and writing ethnography. For this undertake, I am going to use four films, two from Georgia and two from the eastern shores of the Black Sea (Bulgaria and Romania). The discussion proposes a method of teaching through fiction films which traces the interlinks between imagination and representation.

Teaching Global Social Media Through Ethnography
Authors: Sinanan Jolynna Melinda
Published: February 2020

This short piece reflects on both the ethnographic process and the ethnographic products from the Why We Post research project, conducted between 2012 and 2017. I draw attention to the comparative nature of the project, from inception to writing up and how our comparative approach to ethnographic research has formed effective tools for teaching anthropological sensibilities to students of media and digital media studies. In the pedagogical practices that have emerged from the project, I provide examples of images posted to social media platforms and of political engagement in Trinidad as a way of drawing connections between in-depth ethnographic inquiry conducted in what may appear to be parochial or peripheral sites, and emerging trends in global, public discussion. In so doing, I illustrate the ways culturally situated digital practices can become effective and accessible ways for introducing ethnographic research into contemporary teaching contexts.

The Symonds Street Cemetery Project was initially suggested by Auckland Council, which desired to learn more about this first-generation colonial urban cemetery in Auckland, New Zealand. Undergraduate students enrolled in an Anthropological Demography course worked in groups to transcribe demographic information from existing gravestones. The undergraduates’ assignment was to develop a demographic profile of one denominational section, comparing results from their transcriptions with those based on a database of known burials and considering issues of representativeness and preservation. The postgraduates developed their own original research questions relating to gender, migration, and infant mortality. The final transcribed data and student papers were given to Auckland Council for their records and others’ use. The postgraduate students also presented their findings in a public forum. Observed benefits were consistent with the literature on fieldwork and service learning in anthropology and related disciplines, such as increased interest and motivation associated with working with ‘real’ data with a purpose beyond their own learning and assessment. The project thus accomplished specific pedagogical goals related to course content while developing students’ transferable skills and including them in the process of community engagement as contributors to local heritage knowledge and preservation.
ANTHROPOLOGY AND WRITING PEDAGOGY
Authors: Chattaraj Durba
Published: February 2020

In an increasingly interconnected world, learning how to think anthropologically — learning how to think with difference — should be an essential part of the process of higher education. Yet many students may never take an anthropology course during their undergraduate career. In such a milieu, it is important for anthropologists to both teach and actively participate in the curriculum design of the first-year writing seminars that are part of the core curriculum of many universities and colleges globally. While first-year writing programs predominate in the United States and the United Kingdom, they are growing internationally as well, particularly in liberal arts institutions. In this article I argue that anthropologists should teach first-year writing seminars at their educational institutions for three reasons: first, anthropology as a discipline is ecumenical about evidence; thus it introduces students to a wide range of evidentiary practices early on. This broad-based understanding of evidence facilitates transfer across disciplines. Second, encountering anthropology in a writing seminar attracts students towards pursuing majors, minors and elective classes in the discipline. Finally, through the discipline’s core methodology of participant observation, lived experience, rather than a synthesis of pre-existing texts, is the core source from which arguments and conclusions about the social world are derived. In an increasingly unequal world where representation in, and access to, written text is concomitantly unequal, it is important that students are introduced to multiple ways to understand and think about human experience. The methodology of participant observation destabilises slightly for undergraduate students the authority of written text as the main, and, often singular, source of knowledge.
The vocational potential of anthropology: teaching organisational research through practitioner archives
Authors: Cory-Pearce Elizabeth
Published: February 2020

In this article we posit the potential utility of a practitioner archive as data for teaching those studying anthropology to understand and perhaps also to practice organisational research and consultancy ethnographically. We address both the value and challenges of taking a purposively ethnographic approach to organisational work, as these both reflect and may also inform the values and challenges of teaching ethnographically more generally within anthropology programmes. The Tavistock Institute of Human Relations is a not-for-profit social science research and organisational consultancy of charitable status, based in London and in formal operation since 1947. Drawing on archived historical projects of the Institute, we illustrate and explore how a distinctively ethnographic approach to action-orientated research (research undertaken in and with client organisations, which is put into action by implementing changes which are designed to address the organisation’s needs) was achieved in a context of market and other constraints.
The Role of History in the Teaching of Anthropology
Authors: Shankland David
Published: February 2020

Recently, at the RAI we have been encouraging research and discussion into the history of anthropology. This has been yielding most interesting insights, particularly as to the changing role of the RAI over the years. At one of our seminars, however, I was struck by a particular remark made to me by a distinguished retired professor, when he said to me words to the effect; ‘Please don’t be surprised if my colleagues still in post are not here to speak – the history of the discipline is something that one only undertakes after one is retired. Whilst one is still teaching, there is little time to do anything other than be preoccupied with one’s own material’.
Simulations of multi-size solid particles in a modified fluidized bed separator
Authors: Syed Naveedul

This study focusses on the description of the internal state of a modified fluidized bed separator also known as the reflux classifier. The device is a highperformance beneficiating technology employed in many mineral and coal processing industries. A 2D continuum model was used to examine the transport behavior of solid particles within the reflux classifier for a multicomponent mixture under continuous operating conditions. Three different types of feeds comprising solid particles of size ranging 49?421 ?m and densities equal to 1400, 2490 and 5000 kg/m3 were simulated simultaneously under identical process conditions. The feed flux and fluidization velocity were kept at 0.0037 m3/m2s and 0.022 m/s, respectively. A comparison of the simulation results showed that the value of separation size shifted towards lower values, 340, 181 and 90 ?m, when the density of the feed was changed from 1400 to 2490 and 5000 kg/m3, respectively. The data generated through simulations was used to demonstrate the movement of solid particle within the inclined section by plotting the net flux of the solid particles across the inclined channel width. It was observed that the net flux of finer solid particles was higher than the coarser ones within the inclined section.

Walnut (Juglans regia) is an important economic tree specie, and has unique aroma in its leaf. In order to investigate the bioactive and bioenergy characteristic of compounds in ethanol and benzene extracts from fresh walnut leaf by gas chromatography/mass spectrometry (GC-MS). The results indicated that ethanol and benzene extracst fresh walnut leaf contain abundant alcohols, aromatic hydrocarbons, quinones, phenols, aldehydes, acids, ketones, alkanes, esterscompounds, especially including dl-.alpha.-Tocopherol, juglone, squalene andlupeol, which are important bioactive components. The functional analytic result suggested that compounds from fresh walnut leaf extracts can be developed into raw materials for industries of biofuel, biomedicine, cosmetic, spices and food additive. The ethanol extract of fresh walnut leaf is more rich in biomedicine and food additives components, such as ketones, alkanes, aldehydes, amines, and acides compounds. The benzene extract of fresh walnut leaf is more rich in biofuels, spices, and cosmetic components, such as phenols, aromatic hydrocarbons, olefines and quinones compounds.

For safety reasons, the need of a fast in situ technique for measuring change in surface hardness of nuclear reactor vessel walls due to ion bombardment has great importance. Material hardness measurement using laser induced breakdown spectroscopy has been demonstrated as a new promising technique. The effect of the material matrix is one of the challenges that this technique for hardness measurement may face. In this work, the plasma excitation temperature Te has been used to measure the relative hardness of some pure Ti and Ti alloy samples with different hardnesses. The hardness of these samples was changed by irradiating the samples with 1 MeV carbon (C) ions with different doses. On studying the average crystallite size of these samples using x-ray diffraction and its relation with hardness, it was found that pure Ti samples and Ti alloys show different behaviors. On the other hand, it was found that although there is a good linear relation between Te and the Vickers hardness, the sample matrices have a strong influence on the measurements, especially for samples with small hardness value differences, irrespective of their average crystallite size.
