Authors: Zambrano Juan C. , Echeverri Zuluaga José Julián , López Herrera Albeiro
Published: July 2019

Objetivo. Determinar la precisión y el sesgo de predicción de valores genómicos directos (VGD) usando genotipos imputados a densidad media, en características productivas y reproductivas en ganado Holstein de Antioquia, Colombia. Materiales y métodos. Fueron genotipificados 31 animales con el chip Illumina BovineLD, 64 con el chip Illumina BovineSNP50v2 y 48 con el chip Illumina BovineHD. La imputación se realizó usando dos paneles de SNPs (6K y 40K) a una densidad 44K, usando el programa FINDHAP.f90 v4. Los efectos de los SNPs fueron estimados mediante el método bayes_C, usando genotipos de baja densidad (6K) y genotipos imputados a una densidad media (44_imputado). La precisión y el sesgo de los VGDs fueron determinados mediante validación cruzada. Las características evaluadas fueron: producción de leche (PL), porcentaje de proteína (PRO), porcentaje de grasa (GRA), puntaje de células somáticas (SCS), intervalo entre partos (IEP) y días abiertos (DA). Resultados. Las precisiones de VGD (rpVGD;EBV) en todas las características evaluadas oscilaron entre 0.19 y 0.24 y el sesgo (bVGD;EBV) entre 0.03 y 0.16 cuando se usó el panel 6K y usando el panel 44K_imputado las precisiones fueron mayores, oscilado entre 0.24 y 0.33 y sesgo entre 0.03 y 0.26. Conclusiones. La precisión de predicción de los VGDs fue mayor cuando se usaron genotipos imputados a densidad media, en comparación con la precisión de predicción obtenida empleando genotipos de baja densidad. Por lo cual, en este estudio se concluye que la imputación de genotipos es muy útil dado que aumenta la confiabilidad de la evaluación genómica.

Authors: LaMonica Haley M , Davenport Tracey A , Burns Jane , Cross Shane , Hodson Stephanie , Veitch Jennifer , Hickie Ian B
Published: July 2019

Background

The impact of mental ill-health on every aspect of the lives of a large number of Australian Defence Force (ADF) personnel, their partners, and their families is widely recognized. Recent Senate inquiries have highlighted gaps in service delivery as well as the need for service reform to ensure appropriate care options for individuals who are currently engaged with mental health and support services as well as for those who, for a variety of reasons, have not sought help. To that end, successive Australian governments generally and the Department of Veterans’ Affairs specifically have prioritized veteran-centric reform. Open Arms is an Australia-wide service that provides counseling and support to current and former ADF personnel, and their family members, for mental health conditions.

Objective

The aim of this study was to develop and configure a prototypic Web-based platform for Open Arms – Veterans & Families Counselling (formerly Veterans and Veterans Families Counselling Service) with the Open Arms community to enhance the quality of mental health services provided by Open Arms.

Methods

The study aimed to recruit up to 100 people from the Open Arms community (current and former ADF personnel and their families, health professionals, service managers, and administrators) in regions of New South Wales, including Sydney, Canberra, Maitland, Singleton, and Port Stephens. Participants were invited to participate in 4-hour participatory design workshops. A variety of methods were used within the workshops, including prompted discussion, review of working prototypes, creation of descriptive artifacts, and group-based development of user journeys.

Results

Seven participatory design workshops were held, including a total of 49 participants. Participants highlighted that the prototype has the potential to (1) provide the opportunity for greater and better-informed personal choice in relation to options for care based on the level of need and personal preferences; (2) ensure transparency in care by providing the individual with access to all of their personal health information; and (3) improve collaborative care and care continuity by allowing information to be shared securely with current and future providers.

Conclusions

Our findings highlight the value of actively engaging stakeholders in participatory design processes for the development and configuration of new technologies.
Exploring Mental Health Professionals’ Perspectives of Text-Based Online Counseling Effectiveness With Young People: Mixed Methods Pilot Study (Preprint)
Authors: Navarro Pablo , Sheffield Jeanie , Edirippulige Sisira , Bambling Matthew
Published: July 2019

BACKGROUND

Population-based studies show that the risk of mental ill health is highest among young people aged 10 to 24 years, who are also the least likely to seek professional treatment because of a number of barriers. Electronic mental (e-mental) health services have been advocated as a method for decreasing these barriers for young people, among which text-based online counseling (TBOC) is a primary intervention used at many youth-oriented services. Although TBOC has shown promising results, its outcome variance is greater in comparison with other electronic interventions and adult user groups.

OBJECTIVE

This pilot study aimed to explore and confirm e-mental health professional’s perspectives about various domains and themes related to young service users’ (YSUs) motivations for accessing TBOC services and factors related to higher and lower effectiveness on these modalities.

METHODS

Participants were 9 e-mental health professionals who were interviewed individually and in focus groups using a semistructured interview. Thematic analysis of qualitative themes from interview transcripts was examined across the areas of YSU motivations for access and factors that increase and decrease TBOC effectiveness.

RESULTS

A total of 4 domains and various subthemes were confirmed and identified to be related to YSUs’ characteristics, motivations for accessing TBOC, and moderators of service effectiveness: user characteristics (ie, prior negative help-seeking experience, mental health syndrome, limited social support, and perceived social difficulties), selection factors (ie, safety, avoidance motivation, accessibility, and expectation), and factors perceived to increase effectiveness (ie, general therapeutic benefits, positive service-modality factors, and persisting with counseling despite substantial benefit) and decrease effectiveness (ie, negative service-modality factors).

CONCLUSIONS

Participants perceived YSUs to have polarized expectations of TBOC effectiveness and be motivated by service accessibility and safety, in response to several help-seeking concerns. Factors increasing TBOC effectiveness were using text-based communication, the online counselor’s interpersonal skills and use of self-management and crisis-support strategies, and working with less complex presenting problems or facilitating access to more intensive support. Factors decreasing TBOC effectiveness were working with more complex problems owing to challenges with assessment, the slow pace of text communication, lack of nonverbal conversational cues, and environmental and connectivity issues. Other factors were using ineffective techniques (eg, poor goal setting, focusing, and postcounseling direction) that produced only short-term outcomes, poor timeliness in responding to service requests, rupture in rapport from managing service boundaries, and low YSU readiness and motivation.

Impact of Women Directors on Corporate Financial Performance-Indian Context
Authors: Das Pradip Kumar
Published: July 2019

Good corporate governance creates the properly structured board of directors capable of taking independent decisions for the welfare of the company. Women directors or female directors with varied backgrounds and experiences tend to look at problems and solutions from wider perspectives, thereby, diversity in boards has been widely considered as an important contributor to improved decision-making. Against this backdrop, the paper empirically investigates the association between participation of female director on board with the financial performance of corporate, using a sample of 16 listed companies’ board membership in India. The study reflects positive and significant impact of female directors on financial performance in the listed companies. The findings could be scientific basis for Indian company to build the most proper board for themselves and contributes to the existing literature through the empirical evidence with more insight into the effect of corporate governance, particularly female directors on firm outcomes from a typical developing country, India. Thus, it is suggested that Indian companies should think about the femininity on board and in senior management to improve financial viability and performance to achieve sustainable growth.
Reivindicaciones marítimas bolivianas durante la Guerra del Pacífico
Authors: Donoso Rojas Carlos
Published: July 2019

The article examines the negotiations promoted by the governments of Chile and Bolivia to guarantee the country maritime access during the Pacific War, and the role played by Peru in these negotiations. According to the analysis, the Chilean position, although not precisely a determined one on the subject, was initially favorable to guarantee territorial grants. This changed after the Bolivian withdrawal of its military forces in 1880. This lack of determination of the Chilean authorities, which was due to the interest of privileging dominance over the nitrate regions, was interpreted by the Bolivian authorities as a clear will to negotiate their domination over the provinces of Tacna and Arica, transforming thus the country into an effective border between the two belligerent nations.
The role of Bolivia in the conflict lost all relevance after the battle of Tacna, which conditioned its territorial aspirations. With a polarized political class and with a willful perseverance in maintaining its alliance with Peru, the country was unable to reconcile its geostrategic interests with a diplomatic definition that guaranteed a maritime position (or a possible negotiation to obtain it), and whose consequence was the Chilean refusal to make peace on the basis of territorial grants.
Tuberculosis, involucramientos politicos y espacios biosociales en Bolivia
Authors: Saravia Paula Francisca
Published: July 2019

High tuberculosis (TB) prevalence in Bolivia has been a major concern for the national health service as well as for the international health bureaucracy. Based on an ethnography of medical encounters conducted in Bolivia between 2009 and 2013, in this article I discuss the emergence of biosocial spaces in clinical contexts, focusing on those mediated by biomedical authority and technology where TB diagnosed patients engage in treatment. By looking at the intersections between medical discourses and associative practices linked to the scientific and biotechnological fields, I analyze the therapeutic experience of a highly pathologized population, such as the aymara indigenous peoples who suffer from TB, to suggest that healing becomes a process that questions current citizenship frameworks and sociality models. Furthermore, I propose that the biomedical developments of TB treatment show how a natural ““objective”” infectious disease is integrated into the national mechanisms of inclusion and exclusion by framing this illness within the social constructions of race and ethnicity.

Authors: Tukhtakuziev A.
Published: July 2019

The authors have described the required conditions for uniform soil tillage at a given depth. It has been shown that depth wheels of tillage machines should be constantly pressed to the soil surface. The study has confi rmed the need to determine the optimal value of the vertical pressure force exerted by the depth wheels on the soil. (Research purpose) To determine ways to ensure the given depth of tillage and the required uniformity using a mounted plow with a depth wheel. (Materials and methods) The authors conducted theoretical studies using methods of theoretical and agricultural mechanics, as well as analytical geometry. They made a diagram of forces acting on the plow in the process of plowing. (Results and discussion) The authors obtained an analytical relationship to determine the vertical pressure force exerted on the soil by a depth wheel of a mounted plow taking into account dimensions and parameters of a tractor mounting system as well as a plow mounting linkage. The optimal values of vertical distance from the plow supporting plane to its lower connecting points were graphically determined. The authors calculated the optimal numerical values of the parameters taken into account: the vertical distance from the tractor's supporting plane to the attachment point of the lower links of its attachment mechanism is 0.6 meters; the number of bodies installed on a plow – 4; the weight of one plow body is 250 kilograms; the plow effi ciency – 0.7; plowing (tillage) depth – 0.3 meters; horizontal distance from the lower connecting points of the plow to the share point of the fi rst body – 0.45 meter; longitudinal distance between the plow bodies – 1.0 meter; plow landside width – 0.2 meters; coeffi cient of rolling resistance to the depth wheel of the plow – 0.2; the diameter of the depth wheel – 0.5 meters etc. (Conclusions) It has been established that in order to ensure a required plowing depth and uniformity, vertical distance from the supporting plane of four-body plows coupled with 3-4 class wheeled tractors to the lower connecting points should be within 0.703-0.771 meters.

Published: July 2019

The most important task in designing competitive agricultural machinery is the production of parts with long service life. The development of new technologies and materials determines the technical level of agricultural engineering. The plowshare blade is the most loaded and important part, as its parameters determine the quality, energy and economic indicators of the technological operation of plowing. (Research purpose) To determine and confi rm theoretically material and technological parameters of low quality level of domestic plowshares manufactured without the use of modern technologies. Then they analyze construction materials of plowshares and other parts of tillage implements produced by leading foreign companies, and come to a conclusion that lowand medium-carbon boron-containing alloyed and high-alloyed steels are used in their production. Leading global manufacturers of machine parts also often apply surface hardfacing with carbide coatings. (Results and discussion) The authors have theoretically and experimentally determined the directions of increasing the strength and durability of plowshare working tools. They have chosen basic materials for plowshares basing mainly on the strength parameters. They have conducted comparative laboratory tests of various materials and witness samples (including double-layer ones) for abrasive wear resistance on two bench installations; identifi ed materials for carbide coatings, clarifi ed the relative wear resistance coeffi cients of steel carbide layers recommended for use in the design of plowshares; and considered a technological method of hardening machine working tools. (Conclusions) The authors propose a simplifi ed computational procedure for selecting design and material parameters (thickness and width of hardening coatings) of plowshare blades and over-chisels, depending on the wear characteristics of the materials used and the plowshare thickness. They have stated mathematical relationships that determine the linear wear of plowshare blades and chisels depending on the characteristics of the materials used, design parameters, soil conditions and total operation time and carried out comparative operational and duration testing of newly developed plowshares. It has been shown that the marginal operating time of new products exceeds the duration indicators of serial counterparts in diff erent soil and climatic conditions in 3.5-5.5 times.

Published: July 2019

Excessive and unbalanced use of the pesticides that is necessary to protect agrophytocenoses against pests leads to environmental pollution. Harmful pesticides tend to enter the natural cycles of substances. Therefore, they are quick to disappear or be destructed by biological agents. There are also “nondestructive” pesticides, which do not enter the natural cycles; neither they are accumulated in food chains and in biotopes. These substances have become an object of research in the fi eld of environmental safety.

Authors: Uvarov R. A.
Published: July 2019

Development and testing of new more effi cient and environmentally friendly waste management technologies is one of the priorities of agroecology aimed at introducing the basic principles of the sustainable use of natural resources. An example of such a technology may be the recycling of cattle manure into the bedding for farm animals. (Research purpose) Feasibility study of diff erent technological options for the production of bedding from manure under conditions of an operating livestock enterprise. (Materials and methods) In the study, three options of this technology were considered as exemplifi ed by a dairy farm for 100 milking cows: Option 1 – separation of manure into fractions followed by aerobic fermentation of the solid manure fraction in a drum-type fermentor; Option 2 – mixing the unprocessed manure with peat and its subsequent aerobic fermentation in a drumtype fermentor; Option 3 – mixing the unprocessed manure with peat and its subsequent aerobic fermentation in a chambertype fermentor. The author has estimated capital and operation costs as well as labour inputs and payback period. (Results and discussion) The number of facilities and equipment required for manure recycling and the resulting product storage has been calculated for each option. The author has made an economic assessment of the three options. For Option 1, the capital costs of implementation amount to 18.2 million roubles, operating costs – 8.9 million roubles, labour inputs – 5.1 man-hour per tonne, and the payback period – 2.1 years. It has been revealed that options 2 and 3 feature high capital costs, therefore, bedding production with the use of peat proved to be ineffi cient. (Conclusions) The study has allowed to determine the most effi cient and economically feasible technological method of manure recycling: manure separation into fractions with subsequent aerobic fermentation of the solid fraction in a drum-type fermentor. Options 2 and 3 have been found economically unfeasible.

Anopheles vagus is one of the vectors that plays an essential role in malaria infection in East Nusa Tenggara, Indonesia. This vector’s density is related to population dynamics and the environment.  The high population density is fluctuated according to the birth and death rate of the mosquitos on their life cycle. This is an observational study that employed a cross-sectional design aimed to identify the life cycle of pre-adult An. vagus mosquitos. The sample was collected from Manggarai Barat and Kupang regions. Sample was taken from around cattle’s cages between 6.00pm-12.00am and were the ones that have sucked cattle’s blood. Identification and colonization were conducted in Loka Litbangkes Waikabubak Laboratory. Data was collected through an hourly observation form and then analyzed descriptively. The results indicated that an adult An.vagus could produce 42-184 eggs each time it laid eggs with 79% hatching rate succeed. The life cycle of an An.vagus under a controlled environment in the laboratory was as following phases: egg (1-4 days), larvae (9-19 days), pupa (1-8 days). Anopheles vagus needed an average of 57.2 minutes to mate and 13 hours to suck blood after the mating process. The highest death rate (28.05%) occurred in instar IVof larvae stage. Pre-adult of An. vagus needed 11-31 days in with the environment that conditioned at 21.1°C and 74.3% humidity for their development,while the highest death rate observed at instar IV.

The roots of the idea of humanitarian intervention in De Iure Belli ac Pacis by Hugo Grotius
Authors: Novakovic Marko
Published: July 2019

Hugo Grotius is rightfully considered as one of the ?fathers? of
international law, although among his contemporaries and predecessors were
many theorists that contributed significantly to the foundations of
international law as we know today. The notion of humanitarian intervention
has its place in his famous book De Iure Belli ac Pacis. The only correct
way to investigate the emergence of the humanitarian intervention as an idea
in this masterpiece of international law is through the analysis set in an
appropriate time context, with particular attention devoted to the life and
work of Hugo Grotius - the approach that will be taken by the author.
Special reference will be given to the progressive ideas of Hugo Grotius in
De Iure Belli ac Pacis in the context of the politics of colonization of the
Dutch in XVII century. Finally, this paper will demonstrate that Hugo
Grotius? book cannot be considered without accepting its utilitaristic
dimension and especially not as a work devoted only to the goals of his
state. As it often happens, the truth is somewhere between two radical views
(and not necessarily in the middle) and consequently, through the glasses of
the interconnection of many factors, his work should be perceived.
Analysis of humanoid robotics for nuclear disaster management incorporated with biomechanics
Authors: Jang Kyung , Woo Tae
Published: July 2019

The humanoid is investigated for the mechanical and physical aspect in the nuclear disaster, especially for a severe accident, which includes the core melting. There are some mechanical studies of the leg and hand of the humanoid in which the human mimicking features are described. The management of the task is accomplished by the three regional preparations. The robot is made of the radiation-resistance substance. Therefore, it could work on the normal task of a human for the removal of the broken debris in a collapsed building. However, there is a limitation for the use in the reactor core building due to very high temperature of the nuclear fuel. The regional classification of the site is studied for the practical purposes. The post-accident analysis is accompanied with multidisciplinary research for the humanoid development in the nuclear industry.

Published: July 2019

Family Care giving for relatives with Alzheimer, often includes assisting them with one or more activities of daily living, as Alzheimer is one of the progressive impairment diseases in patient’s physical and cognitive ability. The aim of this study is to assess the effect of being a family caregiver of Alzheimer patients in Sulaimani city. A cross-sectional quantitative study carried out among family members who care for older patients with Alzheimer’s disease. The instrument was designed and constructed by the researcher through an intensive review of the literature and also through a series of meeting survey with caregivers in order to measure the variables underlying the present study. The data were obtained by the researcher, who interviewed families, structured questionnaire forms filled out with a total of 100 families. These were taken using a random sample of those families have Alzheimer’s problem in Sulaimani city. The majority of participants were women with a mean age 53.75 years old, married, housewives and with university education. More than half of the Caregiver was suffered from moderate to severe burdens.  Rotated Component Matrix was used to get the level of effectiveness by a series of components according to the important effects of the variables on Alzheimer disease. The researcher found that the financial burden has taken the first order, followed by psychological and then a social burden. The finding of the study shows a significant relationship between some demographic characteristics and the three dimensions of the burden. It appears that financial factor is in the first rank by a total variance (85.151), then psychological factors by a total variance (81.532) then the social factor by total variance (65.851). Financial factor was the strongest factor that impacted their family income. Some psychosocial oriented services are recommended for the caregivers in order to decrease the stress and help them to adapt to the situation. Some educational programs are also required to facilitate providing enhanced physical and psychological care. This study also recommends allocating salary for every patient to ease the financial burden on the caregivers

Published: July 2019

Archivo y cuerpo quedan indisolublemente unidos cuando emergen las nuevas tecnologías ópticas de registro y reproducción de imágenes a mitad del siglo XIX. Aunque son diversos los ámbitos e instituciones que consolidarán su poder a partir del uso disciplinario del archivo, entre otras tecnologías de control individual y social, es la institución médica y más concretamente la clínica neuropsiquiátrica donde la imagen ayudará a legitimar unas prácticas y a imponer unos discursos sobre lo normal y sobre lo patológico en relación al cuerpo que transformarán los paradigmas epistemológicos y visuales de la modernidad. Asimismo, en un contexto de hipervisibilidad y de nuevas mediaciones, cabe preguntarse el papel de los diferentes agentes implicados en las alteraciones del imaginario médico finisecular toda vez que las imágenes realizadas intramuros circulan, proliferan y se extienden fuera del entorno médico gracias las nuevas tecnologías visuales de reproducción mecánica como la fotografía y el cinematógrafo.
Avant-Garde Photographics: Multidisciplinary Precedents Advancing Transdisciplinary Arts into the New Century
Authors: Yates Steve
Published: July 2019

La aparición de la vanguardia fotográfica a comienzos del siglo XX tuvo un carácter multidisciplinar, buscando nuevas direcciones en las que avanzar. Dichas transformaciones supusieron una era proto-moderna estrechamente relacionada con las vanguardias europeas. Nuevas formas de expresión fotográfica con una diversidad sin precedentes, al tiempo que establecía las bases para una práctica y estrategia artísticas transdisciplinares que continúan siendo hoy día un revulsivo para las tradiciones, limitaciones y fronteras del medio.Las aportaciones de los diferentes artistas contribuyeron a la aparición de nuevas formas de fotografía proto-moderna, tanto en el ámbito de la cámara y el cuarto oscuro como yendo más allá de sus límites. Las tecnologías emergentes en la época, los nuevos materiales y soportes posibilitaron la evolución del arte moderno más allá de las disciplinas tradicionales. Algunas de las aportaciones de la fotografía proto-moderna, como el fotomontaje, los fotogramas, algunos avances en el ámbito del cine, el diseño de las exposiciones y el color, publicitados a través de los medios impresos, permitieron explorar las influencias mutuas entre soportes y medios.La fotografía de vanguardia coexistió con el sistema de las artes, que separaba las prácticas tradicionales al tiempo que señalaba sus límites. El abandono del arte convencional supuso un impulso para la exploración de las posibilidades de la fotografía.La transdisciplinariedad del arte contemporáneo ha acabado con las tradicionales diferencias de géneros y temas. El pasado multimedia ha dado paso a ideas fotográficas en las que ya no existen las categorías, los relatos pertenecientes a la tradición de la historia del arte o sus divisiones. La dicotomía entre real y abstracción, subjetivo y objetivo, veracidad construida y documentalismo, la eliminación de la diferencia entre original y copia, nos permiten llevar las ideas de las vanguardias al siglo XXI, más allá de la era moderna.
La mirada hipermétrope: el fotoperiodismo en la era de las redes sociales
Authors: Marcos Molano Mar , Tagarro Ana
Published: July 2019

La difusión de fotografías vinculadas a la actualidad a través de las redes sociales antes incluso de ser publicadas en los medios de comunicación, ha alterado el rol tradicional de fotógrafos y de editores gráficos. Estas fotografías, vistas por millones de personas en todo el mundo y cuya difusión se produce a través de Twitter, Facebook o Instagram, eluden la fase de edición gráfica otrora fundamental en todo proceso de comunicación periodística, pues es en esta fase donde se otorga un sentido concreto y consciente a las imágenes. Esto supone que las fotografías son publicadas sin atender a ninguna estrategia de planificación ni revisión de la producción, lo que deriva en un uso descontrolado de la imagen periodística. Pero no solo ha sido eliminado el criterio de selección con la desaparición del editor gráfico, también la autoría, con fotógrafos fagocitados por los propios sujetos retratados, en imágenes donde no hay firma ni copyright, y donde la mirada del autor parece haber sido desplazada del visor de su cámara.
Shame (2011) de Steve McQueen. El cine en segundo grado: la hipertextualidad
Authors: Díaz Gito Manuel Antonio
Published: July 2019

El objetivo de este trabajo es proponer la existencia de una relación transtextual de hipertextualidad entre Shame (2011), película dirigida por el director británico Steve McQueen, y American Psycho de Mary Harron (2000), adaptación cinematográfica de la novela homónima de Bret Easton Ellis (1991). El fundamento de esta hipótesis descansa tanto en la similitud de los respectivos argumentos y de los recursos cinematográficos (estructurales, transtextuales y retóricos) empleados en las dos películas, como en la intención artística de los cineastas. En un trabajo subsiguiente, se identificará y analizará una serie de citas intertextuales de diferente procedencia también presentes en el filme de McQueen. La superposición de diferentes discursos convierte a Shame en un rico palimpsesto transtextual que proyecta su propio significado a partir de la suma de las significaciones de sus textos subyacentes. Parafraseando la fórmula del semiólogo literario francés Gérard Genette, cuya metodología ha servido de base para el análisis, Shame de Steve McQueen resulta un buen testimonio de “cine en segundo grado”.
Todo lo solido se desvanece en el aire. Sobre atraco perfecto (The killing, Stanley Kubrick, 1956)
Authors: Verardi Malena
Published: July 2019

El presente trabajo se propone analizar el film Atraco perfecto (The Killing, Stanley Kubrick, 1956), poniendo en relación la configuración narrativa del relato con la conformación de significaciones sobre el contexto histórico y político en el cual se inscribe la película. El abordaje de la organización formal del film se centra en el estudio de los modos de representación y construcción del tiempo y el espacio, en tanto el contexto histórico se analiza considerando la inscripción del film noir (cine negro) en la sociedad estadounidense de posguerra. De esta manera, el análisis de la organización formal del film se presenta como el eje a partir del cual problematizar una determinada coyuntura socio-histórica. El abordaje planteado no supone entender al cine como una instancia que ilustra un momento histórico sino, antes bien, busca analizarlo a través de los vínculos que establece con el contexto social del cual forma parte y al cual contribuye a conformar.
