Interaction among estrogen, IGF-1, and H2S on smooth muscle cell proliferation
Authors: Shuang Tian , Fu Ming , Yang Guangdong , Huang Ying , Qian Zhongming , Wu Lingyun , Wang Rui
Published: October 2020

Both estrogen and hydrogen sulfide (H2S) inhibit the proliferation of vascular smooth muscle cells (SMCs) and development of atherosclerosis. In the absence of endogenous H2S as occurred in CSE-knockout (KO) mouse, however, estrogen stimulates the proliferation of vascular SMCs. The underlying mechanisms for this seemingly controversial vascular effect of estrogen are unclear. In the present study, we demonstrated that the stimulatory effect of estrogen on the proliferation of CSE-KO SMCs was suppressed by the inhibitor of insulin-like growth factor-1 receptor (IGF-1R) or knockdown of IGF-1R protein expression. Estrogen downregulated the expression of insulin-like growth factor-1 (IGF-1) and IGF-1R in aortic tissues or aortic SMCs isolated from WT and CSE-KO mice. Furthermore, endogenous H2S downregulated IGF-1R, but upregulated estrogen receptor (ER)-α, in aortic tissues or SMCs. ER-α and IGF-1R were co-located in SMCs and co-immunoprecipitated, which was decreased by H2S. Finally, both endogenous and exogenous H2S induced the S-sulfhydration of IGF-1R, but not ER-α, in WT-SMCs and CSE-KO SMCs, which underlies the decreased formation of IGF-1R/ER-α hybrid in the presence of H2S. Thus, the absence of H2S favors the interaction of estrogen with IGF-1R/ER-α hybrid to stimulate SMCs proliferation. The appreciation of a critical role of H2S in preventing estrogen-induced SMCs proliferation will help better understand the regulation of complex vascular effects of estrogen and sex-related cardiovascular diseases.
Liver at the nexus of rat postnatal HPA axis maturation and sexual dimorphism
Authors: Toews Julia N C , Hammond Geoffrey L , Viau Victor
Published: October 2020

Normal function of the hypothalamic–pituitary–adrenal (HPA) axis is critical for survival, and its development is choreographed for age-, sex- and context-specific actions. The liver influences HPA ontogeny, integrating diverse endocrine signals that inhibit or activate its development. This review examines how developmental changes in the expression of genes in the liver coordinate postnatal changes in multiple endocrine systems that facilitate the maturation and sexual dimorphism of the rat HPA axis. Specifically, it examines how the ontogeny of testicular androgen production, somatostatin-growth hormone activities, and hypothalamic-pituitary-thyroid axis activity intersect to influence the hepatic gene expression of insulin-like growth factor 1, corticosteroid-binding globulin, thyroxine-binding globulin, 11β-hydroxysteroid dehydrogenase type 1 and 5α-reductase type 1. The timing of such molecular changes vary between mammalian species, but they are evolutionarily conserved and are poised to control homeostasis broadly, especially during adversity. Importantly, with the liver as their nexus, these diverse endocrine systems establish the fundamental organization of the HPA axis throughout postnatal development, and thereby ultimately determine the actions of glucocorticoids during adulthood.

A reduction in hepatocyte growth hormone (GH)-signaling promotes non-alcoholic fatty liver disease (NAFLD). However, debate remains as to the relative contribution of the direct effects of GH on hepatocyte function vs indirect effects, via alterations in insulin-like growth factor 1 (IGF1). To isolate the role of hepatocyte GH receptor (GHR) signaling, independent of changes in IGF1, mice with adult-onset, hepatocyte-specific GHR knockdown (aHepGHRkd) were treated with a vector expressing rat IGF1 targeted specifically to hepatocytes. Compared to GHR-intact mice, aHepGHRkd reduced circulating IGF1 and elevated GH. In male aHepGHRkd, the shift in IGF1/GH did not alter plasma glucose or non-esterified fatty acids (NEFA), but was associated with increased insulin, enhanced systemic lipid oxidation and reduced white adipose tissue (WAT) mass. Livers of male aHepGHRkd exhibited steatosis associated with increased de novo lipogenesis, hepatocyte ballooning and inflammation. In female aHepGHRkd, hepatic GHR protein levels were not detectable, but moderate levels of IGF1 were maintained, with minimal alterations in systemic metabolism and no evidence of steatosis. Reconstitution of hepatocyte IGF1 in male aHepGHRkd lowered GH and normalized insulin, whole body lipid utilization and WAT mass. However, IGF1 reconstitution did not reduce steatosis or eliminate liver injury. RNAseq analysis showed IGF1 reconstitution did not impact aHepGHRkd-induced changes in liver gene expression, despite changes in systemic metabolism. These results demonstrate the impact of aHepGHRkd is sexually dimorphic and the steatosis and liver injury observed in male aHepGHRkd mice is autonomous of IGF1, suggesting GH acts directly on the adult hepatocyte to control NAFLD progression.
Taming of the Tiger: A Novel Technique to Deal With Mitral Annular Calcification —A Case Series
Authors: Panicker Varghese , Sreekantan Renjith , Kotera Sai Suraj
Published: October 2020

Background: Mitral valve surgery can be challenging for patients with mitral annular calcification (MAC). The prevalence of MAC in patients who undergo mitral valve replacement is 19.9%. The  treatment options for MAC include complete decalcification and annular reconstruction with valve repair/replacement or performing a surgical valve repair or replacement without decalcification, accepting the risk of paravalvular leak. We describe three cases of mitral valve prolapse with posterior annular calcification, which were repaired using a unique technique that does not require decalcification.
Case reports: The mitral annular calcification was heavy and involved most of the posterior annulus just sparing the commissures in all the three cases. Leaflet prolapse was dealt with by using neochordae, closing any clefts, and leaflet plication. Since the MAC ring was not complete and there was chance of further dilatation of the annulus, a partial annuloplasty was done using a PTFE felt (cut as strip). There was trivial to no mitral regurgitation with this technique in the immediate postoperative and five-year follow-up period echocardiography in all the three cases.
Conclusion: This technique can benefit the major subset of pure mitral valve regurgitant lesions associated with MAC, which is limited to the posterior annulus.
On the Lie structure of locally matrix algebras
Authors: Bezushchak O.
Published: October 2020

Let $A$ be a unital locally matrix algebra over a field $\mathbb{F}$ of characteristic different from $2.$ We find a necessary and sufficient condition for the Lie algebra $A\diagup\mathbb{F}\cdot 1$ to be simple and for the Lie algebra of derivations $\text{Der}(A)$ to be topologically simple. The condition depends on the Steinitz number of $A$ only.

Published: October 2020

Stem cells are tightly controlled in vivo. Both the balance between self-renewal and differentiation and the rate of proliferation are often regulated by multiple factors. The Caenorhabditis elegans hermaphrodite germ line provides a simple and accessible system for studying stem cells in vivo. In this system, GLP-1/Notch activity prevents the differentiation of distal germ cells in response to ligand production from the nearby distal tip cell, thereby supporting a stem cell pool. However, a delay in germline development relative to somatic gonad development can cause a pool of undifferentiated germ cells to persist in response to alternate Notch ligands expressed in the proximal somatic gonad. This pool of undifferentiated germ cells forms a proximal tumor that, in adulthood, blocks the oviduct. This type of “latent niche”-driven proximal tumor is highly penetrant in worms bearing the temperature-sensitive weak gain-of-function mutation glp-1(ar202) at the restrictive temperature. At the permissive temperature, few worms develop tumors. Nevertheless, several interventions elevate the penetrance of proximal tumor formation at the permissive temperature, including reduced insulin signaling or the ablation of distal-most sheath cells. To systematically identify genetic perturbations that enhance proximal tumor formation, we sought genes that, upon RNAi depletion, elevate the percentage of worms bearing proximal germline tumors in glp-1(ar202) at the permissive temperature. We identified 43 genes representing a variety of functional classes, the most enriched of which is “translation”. Some of these genes also influence the distal germ line, and some are conserved genes for which genetic interactions with Notch were not previously known in this system.

Branded Employee Behaviour as a Double-Edged Sword: How Perceptions of Service Employees Impact Job Seekers' Application Intentions
Authors: Wünderlich Nancy V. , Iseke Anja , Becker-Özcamlica Hürrem
Published: October 2020

Prior brand experiences affect job seekers’ application decisions, as they recall service encounters with brands which they have experienced as customers. As brand representatives, service employees play a critical role in these recollections. Their behaviour might inform job seekers’ understanding of the employer brand, thereby affecting their application decision. The impact of the service employee’s behaviour might be even more impactful if this behaviour is branded, meaning that the employee’s appearance and manner are representative of the brand values. In this paper, we analyse whether and how branded service employee behaviour affects job seekers’ application intentions. We argue that branded service employee behaviour provides two opposing signals: it contributes to consistent evaluations of the brand, leading to more brand trustworthiness and enhancing job seekers’ application intentions. However, it may also be perceived as inauthentic, reducing job seekers’ application intentions. Findings from a scenario experiment provide evidence of both effects.
Stereotypes in Services - A Systematic Literature Review to Move from Scattered Insights to Generalizable Knowledge
Authors: Fleischer Hannes
Published: October 2020

Over the last 40 years, the impact of stereotypes in a service context has been investigated repeatedly, as stereotypes can have a strong influence on interactions during the service encounter. The many academic studies analysed various stereotypes, took a customer or employee perspective, investigated attitudinal or behavioural outcomes before and after an interaction and found both positive and negative effects of stereotypes. Thus, a synthesis of research is needed that integrates existing knowledge to clarify what researchers have learnt about stereotypes in services. The main contribution of our research is to aggregate and categorise the highly specialized findings that exist on specific stereotypes and thus make the current knowledge more generalisable. The results of our study reveal that a strong focus on customer stereotypes regarding employees exists, but other stereotype constellations are less often investigated. Similarly, the investigation of more subtle stereotype triggers and the consideration of contextual factors should receive more attention. Finally, even as we identified meaningful managerial implications to address the consequences of stereotypes, academic papers need to include a practitioner’s perspective more consequently.
Determinación de Necesidades de Capacitación del Personal Administrativo del Área de Ciencias Económicas y de la Gestión de la UNMSM
Authors: Ugarte Casafranca Walter Davis , Melgar Campos Teresa Victoria , Tacillo Yauli Elvis Fernando
Published: October 2020

Presentamos el avance del proceso de capacitación del personal administrativo de las facultades del área de ciencias económicas y de la gestión de la Universidad Nacional Mayor de San Marcos (UNMSM) en el marco de la implementación de la Ley del Servicio Civil. Se han desarrollado entrevistas a los funcionarios encargados de la gestión administrativa y aplicado un cuestionario al personal administrativo para determinar las necesidades de capacitación. Asimismo, se han estudiado los perfiles de puesto y perfiles personales para los cargos de administración de las referidas facultades. El resultado más resaltante es que se debe hacer hincapié en el desarrollo de habilidades blandas. Entre éstas destacan el trabajo en equipo y la resolución de conflictos. Asimismo, hemos hallado que, debido a la constante rotación de personal y a los bajos salarios, existe personal cada vez menos calificado lo cual es más notorio en el caso de personal contratado. En cuanto a la implementación de la Ley del Servicio Civil, las facultades estudiadas no han implementado ni planes ni presupuesto para la capacitación de su personal administrativo, lo cual pone en peligro la calidad del servicio que prestan. Si bien es cierto la UNMSM está en proceso de mejora se debe reforzar la capacitación del personal puesto que en este ámbito y en la aplicación de la Ley de Servicio Civil estamos todavía atrasados.
Carrying Across or Pulling down? Understanding Translation through its Metaphors: A Cross-linguistic Perspective
Authors: Šeškauskienė Inesa
Published: October 2020

The paper investigates how translation is conceptualised through metaphors employed in academic texts in English and Lithuanian focusing on translation problems. As established by previous research, metaphors are tools of rendering abstract thought in terms of more concrete experiences. The methodology of this investigation is based on the Conceptual Metaphor Theory and further development in metaphor research, the main principles of Metaphor Identification Procedure and metaphorical patterns. The results suggest that English tends to more frequently conceptualise translation as human and also as a dynamic activity, whereas Lithuanian opts for more static conceptualisation of translation in terms of object and material. Such tendencies might be linked, among other factors, to very different etymologies of the verb ‘translate’ and its derivatives in English and Lithuanian as well as other senses of the word.
“Fat Cats on Golden Parachutes” – about an Idiom Derived from the Language of Politics and its Modifications
Authors: Połowniak-Wawrzonek Dorota , Rosińska-Mamej Agnieszka
Published: October 2020

Due to the influence of the language of politics, the noun phrase, tłuste koty, has become established in modern Polish language. As the research material proves, the idiom fat cats has a negative connotation in the Polish language. Most often, it refers to rich people associated with business, as well as politicians and people in power, such as legislative, executive and judicial. The analysed texts provide many modifications of the expression under analysis, e.g., wypasione pisowskie tłuste koty, tłuste koty w sutannach, tłuste koty nadziane ośmiorniczkami, tłuste koty na złotych spadochronach, lejące krokodyle łzy podczas ucieczki z pogromu kociego na Wall Street, najtłustszy i wredny kot, okrąglutki, milutki, taki kotek tłuściutki. The most important function of modification is to express a critical opinion about people in the category of fatty cats. Through modifications, it is emphasized that the earnings of fatty cats are indecently high, often unreasonable and undeserved. Sharp social opposition causes financiers and politicians to avoid being responsible for their mistakes, for dishonesty. Fat cats are also accused of greed.
Expression of Conflict Communication in the Discourse of Presidential Election in Lithuania (2019)
Authors: Linkevičiūtė Vilma
Published: October 2020

The subject matter of the article is different linguistic means of political conflict communication proper to the presidential discourse in Lithuania (2019). The research deals with the conflict communication of the three most popular candidates (according to sociological surveys) – G. Nausėda, S. Skvernelis, and I. Šimonytė. The political discourse of all three candidates is aimed at а positive self-representation; direct or indirect imputations of lack of sustained political commitment from the former president or their political opponents; accusation of pursuing their personal interests, or even making detrimental actions to the state and the society. The most prevalent meaning field in Nausėda’s discourse is welfare – detriment where THEY (former presidents, political parties and their representatives) are granted negative nominations, which are contrasted to positive nominations related to the latter candidate. The most prevailing meaning field in Skvernelis’s discourse is active and responsible state – inactive and irresponsible state which is expressed with the help of two sets of oppositions I – SHE (Grybauskaitė) and I – THEY (Parliamentary opposition and former political majority). The most popular meaning field in Šimonytė’s discourse is welfare – detriment, expressed with the help of I – THEY (members of the Lithuanian Farmers and Greens Union) opposition.
The Cartography of Love in Doris Lessing’s “love, again”
Authors: Miroshnychenko Lilia
Published: October 2020

In her late novel, love, again (1996), Doris Lessing represents a penetrative insight of love, providing the widest perspective of love than in any of her previous work. The abundance and variety of plausible les affaires d’amour, which transgress the boundaries of gender, age, geography, and social status, make love, again Lessing’s most “loveful” novel. The narrative responds to this multiplicity accordingly. The essay explores the theme of romantic love of the central female character, Sarah Durham, who is at the centre of the narrative and whose emotional landscape is meticulously mapped. It also aims to unveil the ways Doris Lessing exploits a longstanding tradition of interpreting love in Western philosophy and culture – from Plato to contemporary theorists, including Alain Badiou. Special attention is paid to the interweaving of love and friendship in the relationship of woman and man as well as friendship’s “healing” power for unrequited love encapsulated in the character of Stephen Ellington-Smith. Also, by tracing the transformative impulse of love, the essay tries to bring light on the constructive (in the case of Sarah) and problematic (Stephen) consequences of love.
“Apple Blossoms” and “The Apple Tree”: Two Perspectives Typological and Ideological Similarities in Short Stories by Mykhailo Kotsiubynsky and John Galsworthy
Authors: Halchuk Oksana
Published: October 2020

The article provides comparative analysis of Apple Blossoms by Mykhailo Kotsiubynsky and The Apple Tree by John Galsworthy. Both authors explore human morality in a crisis of confrontation between sensuality and death, the beauty of life and the beauty of art. At the structural level, the works share an element of paratext, novelistic nature, polysemic images-landscapes, and methods of psychologization. Galsworthy engages the antinomy of the city – province, resorts to irony, and combines elements of impressionist writing with the traditions of realistic socio-psychological prose. In contrast, Kotsiubynsky systematically implements the impressionist fragmentary nature of the composition, symbolism of visual and auditory images, in-depth psychoanalysis, and the conventionality of the chronotope.

The issues of short stories are diversified and aesthetic – as is distinct for modernist literature – implicitly in Kotsiubynsky’s work, and most explicitly through the connections with the Antiquity and English intertext in Galsworthy’s prose.

Content-Related and Methodological Issues in Bilingual and Plurilingual Programmes
Authors:   University of Castilla la Mancha, 13001 Ciudad Real, Spain, Araluce Helena Aikin
Published: October 2020

CLIL programmes have been implemented in a large number of Spanish schools in the last decades as a means of promoting foreign language proficiency and fostering multilingualism and language diversity in order to meet the new demands of our globalized societies. Although Spain is considered one of the European leaders in CLIL practice and research, it nevertheless faces many challenges caused by teachers´ insufficient training both in the target language and in CLIL methodology. While the language-related shortcomings have been identified to a certain extent and remedied through language immersion courses and language assistant programmes, the content-related and methodological issues are still being largely neglected in spite of the fact that there exists considerable CLIL literature where these issues have been addressed. Renowned CLIL authors such as Do Coyle, David Marsh and Peeter Mehisto stress the importance of high quality teaching as key to the success of the CLIL approach; they claim that good CLIL practice not only broadens conceptual mapping resources by boosting cognitive development and metacognitive skills, but it also encourages active, meaningful, “deep” learning, critical thinking and creative thought with the help of scaffolding techniques that facilitate both language and content learning. This paper examines the language practices in content classrooms in the bilingual programmes of Castilla la Mancha. With a view to identifying the main difficulties that both teachers and students face. It also explores different ways of approaching these challenges, most of which are bound to be extensive to the Indian context.
Antithrombotic Therapy after Venous Stent Placement
Authors: Xiao Nicholas , Desai Kush R
Published: October 2020

Chronic deep venous disease (CVD) affects millions of Americans and can result in significant morbidity, such as debilitating lower extremity oedema, venous claudication, and in severe cases, venous ulcers. CVD can be caused by thrombotic and non-thrombotic disease processes, such as deep venous thrombosis and iliac compression syndrome. Recently, endovascular intervention with percutaneous transluminal angioplasty and venous stent placement has become the mainstay therapy for these patients, with several studies demonstrating its safety and efficacy. However, anticoagulation management following venous stent placement is largely unstudied, and there are no large randomised controlled trials or official guidelines establishing an optimal regimen. Most published studies are plagued with data heterogeneity and incomplete reporting. This is further complicated by rapidly evolving improvements in technique and dedicated devices in endovenous intervention. In this article, the authors discuss the current literature to date and offer an approach to anticoagulation and antiplatelet management following venous stent placement in CVD.

Published: October 2020

The paper presents the results of studying the effect of deluvial processes on the formation of macro- and micromorphological properties of forest soils on the example of ravined biogeocenoses of Dnieper Prysamarya. Ravined forest biogeocenoses have a long history of development associated with the evolution of land cover in Postpleistocene epoch. One of the factors of soil formation in ravines is deluvial process as a natural phenomenon typical for the landscapes of the present steppes. Ravined forest soils in the catena in the upper reaches of the ravine Glyboky have been studied. They are situated on the upland part of the watershed-gulch landscape in 2 km tonorth of the Andreevka village Novomoskovsk district Dnepropetrovsk region. The methods of macromorphological and micromorphological study of genetic profiles of soils have been used. It is established that ravined forest ecosystems are subjected to intensive influence of deluvial processes, whereby, morphogenesis of ravined soil has a complex peculiar character, which results to theformation of specific morphological properties. It is revealed that the source rock for the forest chernozem on the slopes and formeadow-forest soils of the thalweg are loamy humus deluvial deposits, unlike the ordinary chernozem near the ravines formed on loess rocks. Modern deluvial deposits are the materialof surface horizons of chernozems adjacent to ravine territories. Ravines act as storage ofhumus material of steppe chernozem rendered by adjacent areas. The peculiarities of the morphological structure of the profiles of the soils indicate the intensity of involvement of deluvial material in the processes forest chernozem formation. The different effects of slope processes on the structure of the investigated soil catenahave been revealed. Ordinary chernozem near forest edges have signs of erosion of the surface horizons, while the forest soils of slopes and thalweg are characterized by superpower profile. It is found that the profile of the thalweg and forest soils tends to develop, increasing its power in the two lateral directions: down – thanks to the vertical flow of substances (lessivage, intensive movement of soil invertebrates, the development of the root system); up – the deposition of lessivage material. Deluvial processes connected with lessivage ones as theytransport the new mass of finely divided material into the body of forest soil.

A number of slices of roots of fruit and nut cultures are thoroughly analysed  in the paper. The architectonic schemes of plant root system along the profile are presented. In the gardens for the each breed of the growing cultures the test indexes of terms  of their optimal growing are given, namely on the dense underlying rocks, in plantaged conditions, in the conditions of buried humus horizons. The power of root systems is examined, depending on the degree of fine earth and humus reserves. The scale of stability growth for the cultural garden plants of Crimea and many other indexes are set: water content in leaves, water intensity of leaves, real water deficit, water loss of leaves, indexes of the productivity, statistical indexes, productivity on the rootstock, hydrothermal coefficients, description of the south black earth,  possible and optimal parameters of the power of the root layer, productivity on black earth, description of the foothill ordinary black earth,  indices of growth and productivity. All data of the grown trees, fruit and fruit and berry cultures pass a statistical treatment with the information about the indexes of the trees’ growth and productivity dependence from the properties of the skeletal soils. At the end of the chapter the theoretical conclusions and the direct recommendations for the practical workers of garden economy are given.
Electrophysical characteristics and dielectric constant of soils of northern natural forests of Ukrainian steppe zone
Authors: Gorban V. A.
Published: October 2020

Currently in soil science the search for new methods and technologies for soil research is relevant, which in a short time allows to receive a large amount of information about its condition with the lowest financial cost. Methods for determining electrophysical parameters and dielectric constant of soils are conforming to these requirements. As a result of the investigations, it was found that the upper horizons of the soils of Glubokiy ravine, located in the Ukrainian steppe zone (Novomoskovsk district, Dnipropetrovsk region, Ukraine), differ to lower values of electrical resistance and dielectric constant compared to the lower horizons. The upper horizons are characterized by increased values of electrical conductivity, mineralization and salinity compared with the lower horizons. Sudden changes in the values of all investigated parameters at the boundary of the eluvial and illuvial horizons were found in Luvic phaeozem of northern exposition of ravine and in Luvic gleyic phaeozem of thalweg. In the Luvic phaeozem of the forest northern exposure of the ravine and in the Luvic gleyic phaeozem of the leveled area of the ravine, sharp changes were found in the values of all the investigated parameters at the boundary of the eluvial and illuvial horizons. In the eluvial horizons of Luvic phaeozem, which bordering on the illuvial horizons, a sharp increase in the dielectric constant is observed. The upper horizons of Calcic chernozem of the northern ravine exposition are characterized by increased values of electrical resistance, electrical conductivity and dielectric constant, as well as lower values of mineralization and salinity compared to the upper horizons of Calcic chernozem of the southern ravine exposition. The upper horizons of the Luvic phaeozem of the forest north exposition of the ravine are characterized by higher values of electrical resistance and dielectric constant compared to the upper horizons of the Luvic phaeozem of the forest south exposition of the ravine. In terms of electrical conductivity, mineralization and salinity, Luvic phaeozems practically don’t differ. The upper horizons of Luvic phaeozems are characterized by lower values of electrical resistance and dielectric constant, as well as higher values of electrical conductivity, mineralization and salinity compared to Calcic chernozems. The results obtained indicate that the highest content of organic matter and water-soluble compounds, as well as the best structurally-aggregate composition, and also the best structural-aggregate composition is characteristic of forest chernozem. This is due to the one that formed on the southern exposition of the ravine and which is characterized by the lowest values of dielectric constant and electrical resistance, as well as the highest values of electrical conductivity, mineralization and salinity.

Published: October 2020

El objetivo de este trabajo es evaluar la eficacia de una política ambiental que promueva la sustitución de energías fósiles por renovables, con la finalidad de reducir gradualmente las emisiones de dióxido de carbono a lo largo de un periodo. Se utiliza un modelo dinámico de equilibrio general computable para la economía mexicana y se simulan escenarios con dos elasticidades de sustitución, cuando se gravan de manera conjunta a dos de los bienes energéticos que usan combustibles fósiles, midiendo sus impactos sobre la producción agregada y el bienestar social. El análisis de los resultados muestra que la eficacia de la política depende de la elasticidad de sustitución. En el escenario rígido es parcialmente efectiva, ya que se reducen las demandas de todas las energías, fósiles y renovables. El escenario flexible resulta ser eficaz, al favorecer la sustitución entre las energías. La reducción es mayor en el escenario rígido que en el flexible. En cada escenario al incrementar el impuesto disminuyen el PIB y el bienestar social respecto al equilibrio de referencia.

Movimientos sociales de víctimas frente a la construcción de políticas públicas con enfoque de género en contextos de violencia
Authors:   ESCUELA SUPERIOR DE ADMINISTRACIÓN PÚBLICA, Cardona Londoño Juan
Published: October 2020

Los desafíos que plantean los acuerdos de paz y el pos acuerdo a la población colombiana son diversos, ante ello el campo académico tiene una responsabilidad intelectual apremiante de brindar elementos que permitan un análisis riguroso que ayude comprender las causas objetivas y subjetivas de un conflicto interno que ha definido la configuración estatal por más de sesenta años. El presente estudio partió desde la conceptualización de nuevos movimientos sociales, para nuestro caso, movimientos sociales que agrupan víctimas mujeres del conflicto armado colombiano; para comprender de este modo, qué papel han jugado estos en la construcción de políticas públicas con enfoque de género en escenarios políticos de violencia. La metodología que se empleo fue de corte hermenéutico, concluyendo que la incidencia de los movimientos sociales que agrupan mujeres víctimas del conflicto armado construcción de políticas públicas con enfoque de género aun es incipiente, esto debido a que no se ha consolidado una política pública diferenciadora para mujeres víctimas del conflicto, en tanto las políticas públicas existentes no reconocen a las mujeres como flanco principal del accionar violento de grupos institucionales y al margen de la ley, esto aumenta los índices de desigualdad en el tratamiento jurídico ante la justicia ordinal y la Jurisdicción Especial para la Paz (JEP).
