Subjetividades de mujeres de sectores populares en la CDMX que se desempeñan en ocupaciones "masculinas"
Authors: Herrera Cristina
Published: December 2018

Esta nota presenta resultados de un estudio desarrollado en la Ciudad de México con mujeres de sectores populares en ocupaciones consideradas masculinas y femeninas. Participaron 109 mujeres en grupos de discusión y en entrevistas en profundidad. El análisis muestra pistas de una des-generización de las relaciones familiares y de pareja, que se vuelve posible cuando los cambios sociales y culturales conducen a un borramiento de las fronteras entre los mundos masculino y femenino que sustentan la división sexual del trabajo. Aparece una tensión entre el deseo de mayor igualdad de género y la resistencia a aceptarla. Todas las mujeres reproducen el discurso de la pareja igualitaria como utopía, pero mantienen férreamente el modelo diferenciado, tanto por identificación como por estrategia, ante los riesgos del individualismo consumista que perciben en su medio y que amenaza especialmente a sus hijos.
Libretas de un escritor viajero: Saer como naturalista amateur
Authors: Maranguello Carolina
Published: December 2018

En este artículo se analizarán las libretas que Saer llevaba en sus viajes por Francia y Latinoamérica pero que utilizaba fundamentalmente para apuntar sus regresos al país, desde 1982 hasta el año 2002. Tanto al hacer anotaciones sobre aspectos observados del paisaje como durante las notas preparatorias para futuros ensayos, Saer cita y reescribe las imágenes y las codificaciones de otros viajeros que tempranamente formalizaron el paisaje del Río de La Plata. Interesará pensar qué operaciones y modos de observación practicados por estos exploradores retoma Saer y cómo los reescribe en función de su propio proyecto escritural e indagar cómo trama su regreso a la ‘zona’ autofigurándose como un naturalista amateur que dialoga fundamentalmente con William Hudson.
Justo en el borde de la zona de certeza. Modos de la memoria en Los planetas de Sergio Chejfec
Authors: Sánchez Silvina
Published: December 2018

Al revisar ciertas aproximaciones críticas a las narrativas sobre la última dictadura militar en Argentina, observamos que Los planetas de Sergio Chejfec se resiste a las interpretaciones disponibles, a los modos usuales de leer y a los intentos de sistematización. El artículo establece vínculos entre tales resistencias y la concepción de la memoria que trabaja la novela. La memoria se configura como un estado de paso que adopta formas imprecisas y transitorias, una experiencia que se sustrae de las organizaciones objetivas del espacio geométrico y del tiempo cronológico. En este sentido, las temporalidades se acoplan con lo espacial: recordar significa reactualizar la estancia del cuerpo en la ciudad, volver a andar para hacer presente lo pasado.
Entre la retórica teatral y el ensayo: la autoconstrucción de Martín Kohan en Museo de la revolución
Authors: Vega María Angélica
Published: December 2018

Puesto que quien enuncia se presenta en sus figuraciones textuales, este trabajo se centra en la autoconstrucción de Kohan en la novela Museo de la Revolución (2006) mediante el uso de la retórica teatral y el género ensayo: primero, se observa un enunciador que desmonta los efectos de sentidos del presente en el que lee los restos del pasado y, luego, un yo que prueba con la novela que es condición de circulación de las notas escritas por un revolucionario en los setenta.

Educación en tiempos de la Confederación Argentina
Authors: Bustamante Jose
Published: December 2018

Este análisis indaga en dos facetas de la política educativa desarrollada bajo el gobierno de la Confederación Argentina en la década de 1850. Por un lado se recuperan rasgos del proyecto alberdiano, sus modulaciones al formularse el artículo quinto de la constitución de 1853, así como las notas introducidas por la reforma de 1860. Luego se estudian aspectos fiscales y educativos de ese gobierno. Con este propósito se atiende a legajos de órdenes de pago del Departamento de Justicia, Culto e Instrucción Pública durante el período comprendido entre 1856 y 1860.
O DIREITO PENAL NO DIREITO DO TRABALHO: APORTES METODOLÓGICOS E CONSTRUÇÃO DE NARRATIVAS, A PARTIR DO OBJETO DO DIREITO DO TRABALHO
Authors: Andrade Everaldo Gaspar Lopes de
Published: December 2018

Este artigo objetiva demonstrar as intersecções entre o Direito do Trabalho e o Direito Penal, a partir da teoria jurídico-trabalhista clássica e da teoria jurídico trabalhista crítica. Para construção de uma narrativa distinta da doutrina clássica, segue aportes metodológicos oriundos da teoria crítica, a fim de problematizar e refutar a ideologia do trabalho-dever contraditoriamente livre/subordinado, como objeto do Direito do Trabalho. O vínculo destes dois ramos do direito não pode ser encontrado por via de um estudo comparativo dos seus institutos, mas de sua gênese – do aparecimento do direito dogmaticament organizado na sociedade moderna. O Estado Moderno utilizou-se de aportes filósofos que desenharam uma ética omnicompreensiva a partir das quais os juristas formularam as sanções normalizadoras, para uniformizar/universalizar e disciplinar legislativamente as relações sociais. Padrões normativos recepcionados por aqueles dois ramos do direito, a quem cabia universalizar disciplinar/coagir condutas individuais e coletivas. O texto apresenta o Direito do Trabalho na categoria de Direito Humano, centrado no trabalho como ontologia do ser social e rejeita a subordinação da força do trabalho ao capital.

Bringing Freire to Socio-economic Rights: A Pedagogy for Meaningful Engagement
Authors: Du Toit Michelle
Published: December 2018

This article considers what it is that makes meaningful engagement meaningful in the adjudication of socio-economic rights. The pursuit of socio-economic transformation relies on citizen participation, as recognised by the South African Constitution and mandated by the Constitutional Court. This article relies on Paulo Freireâ€™s Pedagogy of the Oppressed to substantiate an understanding of and motivation for meaningful engagement as a concept. This academic venture is premised on the notion that meaningful engagement (akin to Freireâ€™s education and liberation theories) should occur with, not for, the afflicted. The article examines what is conceptually necessary for engagement to be truly meaningful and empowering and not to entrench power dynamics. Strong emphasis is placed on the fact that the afflicted need to be involved in changing their circumstances (as they need to be involved in their liberation and education) and that the source of the problemâ€”in this case socio-economic inequality, deprivation or violationâ€”cannot also be the sole source of the solution. Meaningful engagement with the afflicted circumvents a perpetual entrenchment of oppression, to use Freireâ€™s own terminology. A Freirean approach to meaningful engagement could potentially result in effective socio-economic transformation and the disruption of patterns of socio-economic inequality and disempowerment. The relationship between the afflicted and those in power is questioned for its intentionâ€”an intention that is also disrupted by a Freirean approach to empowering the afflicted and recognising their agency, political capacity and human dignity.
The State Standard for the Acquisition Profile of the Collections of Scientific Libraries, its Strengths and Shortcomings
Authors: Stolyarov Yuri N.
Published: December 2018

In 2018, the State Standard R 7.0.102—2018 “Acquisition Profile of Collections of Scientific Libraries. Structure. Acquisition Indicators” was first introduced into the System of Standards for Information, Librarianship and Publishing (SIBID). The aim of the article is to consider in detail the advantages and shortcomings of the new State Standard. This document is of great legal importance and, in essence, determines not only acquisition of collections, but shapes all library activities. The author notes that some of the items are new word in the library collection analysis and collection generation practice: the concept of “Acquisition Indicator”, “Access Point to Electronic Resources” and their definitions; and statement that collection acquisition objects in the research libraries are all kinds of documents, of any periodicity, different semiotic systems, forms of representation, tangible media etc. The article also identified significant deficiencies of the new standard. The author considers unsatisfactory classification of the acquisition sources and equally unsatisfactory recommendation at deep indication on material form to be guided by State Standard 7.72—96 SIBID “Codes of Physical Form of Documents”. In general, the author characterizes the approval of new State Standard as significant event in library theory and practice.

MINT: A Tool to Explore Themes in High Velocity Social Media Data
Authors: Agarwal Nishant , Dasgupta Subhasis , Gupta Amarnath
Published: December 2018

An important aspect of social media analytics is understanding themes, i.e., popular discussion topics, as they evolve in time. Techniques like topic models, which assume a generative model of theme distribution over documents, often suffer from three problems -- they are expensive to compute in real-time, they usually limit the number of topics, and they do not consider the continuous change in the topic proportions, emergence and noise that occurs in social media. To address these problems, we have developed MINT, a framework that uses a non-uniform stochastic model of term occurrence to identify themes as they evolve in real-time, and periodically stores the identified themes in a semi-structured database. MINT therefore supports both theme detection and evolution queries on social media. Themes encode useful information like their rate of growth, changing user communities around them, links to related real-world events, their representative topic-handles, etc., that can be queried upon. We experimentally show that our extracted themes compare well with more traditional methods but performs well in real-time.

Analisis Eksistensi Infimum Image Dari Fungsi Lower Semi-Continuous dari Atas
Authors: Aini Qurratul
Published: December 2018

In some cases in applied mathematics, the continuous function is not used, but rather the weaker function, i.e. lower semi-continuous function from above. One of the basic properties of the function that needs to be known is the existence of the infimum value of the function image. In the case of a continuous function, the existence of infimum is assured by several assumptions, one of which is the function domain which is a closed set and the function is a bounded function. In this paper, we describe the properties that ensure the existence of infimum of the image of a lower semi-continuous function from above. Based on the results, it is found that the existence of infimum of the image of a lower semi-continuous function from above is assured in the domain which is a compact set and also assured if the function is a convex function.

Costos de producción y rentabilidad del cultivo de la papa en el municipio de Zacapoaxtla, Puebla
Authors: Mejía Méndez Guillermo , Castellanos Suárez José Alfredo
Published: December 2018

La presente investigación se realizó en el año de 2017, con el objetivo de determinar los costos de producción del cultivo de la papa en el municipio de Zacapoaxtla, Puebla. Dentro de las ocupaciones económicas de la Sierra Norte de Puebla son pocas las actividades productivas de importancia económica. Los cultivos comerciales que tradicionalmente se vienen sembrando son el café y la papa. En el caso de la papa es un cultivo de mayor valor agregado; sin embargo, tiene gran dependencia de agroquímicos y otros insumos, que los productores locales no pueden en ocasiones solventar, por lo que las ventajas agroclimáticas de la zona han sido aprovechadas por productores empresariales. La estructura de costos de los productores se determinó mediante las expresiones algebraicas basadas en la teoría económica. De acuerdo a los resultados la diferencia de costos de producción y de rendimientos obtenidos entre pequeños productores y grandes productores hace que los primeros sean desplazados por los segundos. Para los grandes productores la actividad es rentable porque lo que son competitivos en el mercado, pero los pequeños productores la actividad les deja poco margen de ganancia por lo que han venido abandonando la producción de papa.
Uma ponte entre o real e o fantástico: leitura de um conto de Maria Isabel Barreno
Authors: Soares Marcelo Pacheco
Published: December 2018

Esse artigo propõe uma leitura ao conto “A ponte”, da escritora portuguesa Maria Isabel Barreno, publicado em 1993. Para isso, fundamenta-se em teorias acerca do fantástico contemporâneo dos críticos Ana Maria Barrenechea, Jean-Paul Sartre e Jaime Alazraki, segundo as quais a manifestação desse gênero no século XX agencia uma compreensão do mundo hodierno e de seus contextos sociais e políticos, tornando assim o fantástico, não obstante a sua narrativa ilógica ou sobrenatural, uma eficiente representação mimética do real. Baseados nisso, verificamos nessa investigação do conto de Barreno uma discussão a respeito das insólitas decisões promovidas pelos círculos de comando do mundo burocrático oficial do Estado, que revelam o descompasso deste com a realidade dos seus cidadãos e da sociedade. Mais especificamente, deparamo-nos com uma análise a respeito da permanência (ou de sua impossibilidade), na contemporaneidade do Portugal dos anos 1990, das já passadas décadas de ditadura salazarista.
Espacialidade gótica e horror em "Sem olhos", de Machado de Assis
Authors: Philippov Renata
Published: December 2018

Este artigo tem por objetivo analisar o conto “Sem Olhos”, de Machado de Assis, pelo prisma da espacialidade gótica, visando a compreender como tal prisma contribui para criar o efeito de terror. Para tal, tomar-se-ão como aparato teórico os estudos de Botting (1996), Punter; Byron (2004) e Cavallaro (2002) sobre o gótico, com o intuito de discutir como isso se configura no conto machadiano e como desloca a convenção gótica de forma irônica.

Published: December 2018

Artikkeli tarkastelee diskurssianalyysin keinoin Suomeen saapuneisiin turvapaikanhakijoihin kohdistuvia integraatio-odotuksia. Siinä pohditaan, millaisia tulkintoja eri paikallistason toimijat, joiden on suoraan tai epäsuorasti mahdollisuus vaikuttaa turvapaikanhakijoiden kokemuksiin ja arkeen vastaanottokeskuksissa, antavat vastaanottotoiminnalle ja kotoutumiselle osana tätä toimintaa. Artikkelissa esitetty analyysi perustuu haastatteluaineistoon, joka on kerätty vuosina 2016 ja 2017 viideltä eri paikkakunnalta, joista jokaiseen avattiin vuonna 2015 turvapaikanhakijoiden vastaanottokeskus.  Integraatio-odotuksia analysoimalla artikkeli tuo esiin, miten vastaanottotoiminnan ja kotoutumisen välisen rajan hämärtyminen virallisella hallinnollisella tasolla mahdollistaa paikallisesti hyvin vaihtelevat tulkinnat vastaanottotoiminnan luonteesta ja tavoitteista. Diskursiivisen neuvottelun tuloksena vastaanottokeskuksiin rakentuvaa sosiaalista todellisuutta artikkeli kuvaa pakotetun toimettomuuden käsitteellä.

Innovations of Governance in Balinese Joged Bumbung Dance in the era of globalization
Authors: Arya Sugiartha I Gede
Published: December 2018

This paper aims to analyze the develpmental dynamics concerning the governance of Balinese Joged Bumbung performances in the era of globalization. Developments being analyzed involve innovations in governance of performance standards. The methodologies utilized in conducting this research include observations, interviews, and literature studies. Post-modern aesthetic theory is utilized for analysis of phenomena such as, receptivity aesthetics and aesthetics in relation to social facts and arts of the community (Mukarovsky, 1970). Organizational innovation is a manifestation of changes in aesthetic functions by the role of supporting art, Baliâ€™s Joged Bumbung which exists as social dance. In recent developments many manifestations of this art form have been ridiculed as joged ngeborÂ  (meaning â€œdrillâ€ with pornographic connotations), also is much appreciated as innovative joged (joged care jani) due to a change in governance of performance standards. This happens because of the interplay of extraneous factors (peopleâ€™s taste and the influence of television entertainment arts), as well as intrinsic forces (creative power and pragmatic attitudes of performers). The taste of the people who want dancers to move in this ngebor mannerÂ  is understood to be pragmatic by the performers whose affirmation of these movement modalities only for the sake of monetary interest (economic goals). Even though there are also Joged Bumbung Bali innovations; which are creative in organizing performances without being eroded to appear as pornographic and are still in demand by the community. The offer of a model of grooming performance, which prioritizes creativity in the development of accompaniment music and dance movements, has been an innovative Baliâ€™s Joged Bumbung as an offer to fight the tendancy to be erotic.
The Centre and the Periphery: Productivity and the Global Networked Public Sphere
Authors: Sekloča Peter
Published: December 2018

The author examines consequences of expansion strategies of commercial network media, and compares them to ideals of open and accessible public communication. These strategies level out the falling rates of profits that the increased productivity of labour is bringing. Counter-measures of media industries manipulate the amounts of variable and constant capital (outsourcing of labour, shifting of depreciation costs on users, and specialisation). These processes, which are specific to platform business models, ultimately give rise to fragmentation, individualisation and ideological homogenisation of the peripheral public. The public becomes ideologically similar to the centres of power, whereas its critical potential and, consequently, its effective political freedom decreases. While both the political and the economic subsystems and the public alike use network communication to organise their activities, interaction between the two social domains (the system and the lifeworld) resembles an ‘interactive top-down communication structure’. Inclusion of citizens-consumers into the productivity race renders interactivity similar to one-way communication.

Compacted Graphite Iron
Authors: Stefanescu Doru M.
Published: December 2018

This article discusses the chemical composition, castability, mechanical properties at room temperature and elevated temperature, and physical properties of compacted graphite (CG) cast iron. The change in graphite morphology from the flake graphite (FG) in the base iron to the CG in the final iron is achieved by liquid treatment with different minor elements. CG irons have strength properties close to those of spheroidal graphite (SG) irons, at considerably higher elongations than those of FG iron, and with intermediate thermal conductivities. The main factors affecting the mechanical properties of CG irons both at room temperatures and at elevated temperatures are composition, structure (nodularity and matrix), and section size. The article also discusses the applications of CG irons that stem from their relative intermediate position between FG and SG irons. The tables in the article list the values for tensile properties, hardness, thermal conductivity, fatigue strengths, endurance ratios, and compressive properties of CG, FG, and SG irons.

Hardenable Carbon and Low-Alloy Steels
Authors: Kuch Eugene R.
Published: December 2018

Carbon steels have wider usage than any other metal because of their versatility and low cost. Required hardenability is the most important factor influencing a choice between carbon- and alloy steel. By increasing hardenability, alloying elements extend the potential for enhanced properties to the large sections required for many applications. Alloy steels are ordinarily quench hardened and tempered to the level of strength desired for the application. Distortion during heat treatment may occur with almost any hardenable carbon or alloy steel, although distortion is usually more severe for carbon grades than for alloy grades of equivalent carbon content. The relatively low hardenability of carbon steels is a primary reason for choosing them in preference to alloy steels for parts that are to be locally heat treated by flame or induction hardening. Fabrication processes are performed on hardenable carbon and alloy steels in the unhardened condition, that is, prior to heat treating.
Hardenability of Carbon and Low-Alloy Steels
Authors: Burrier Harold
Published: December 2018

Hardenability of steel is the property that determines the depth and distribution of hardness induced by quenching. Hardenability is usually the single most important factor in the selection of steel for heat-treated parts. The hardenability of a steel is best assessed by studying the hardening response of the steel to cooling in a standardized configuration in which a variety of cooling rates can be easily and consistently reproduced from one test to another. These include the Jominy end-quench test, the carburized hardenability test, and the air hardenability test. Tests that are more suited to very low hardenability steels include the hot-brine test and the surface-area-center test. The article discusses the effects of varying carbon content as well as the influence of different alloying elements. It includes charts and a table that serve as a general steel hardenability selection guide.

Ferrous Powder Metallurgy Materials
Authors: Pease Leander F.
Published: December 2018

Certain metal products can be produced only by powder metallurgy; among these products are materials whose porosity is controlled. Successful production by powder metallurgy depends on the proper selection and control of process variables: powder characteristics; powder preparation; type of compacting press; design of compacting tools and dies; type of sintering furnace; composition of the sintering atmosphere; choice of production cycle, including sintering time and temperature; and secondary operations and heat treatment. When the application of a powder metallurgy part requires high levels of strength, toughness, or hardness, the mechanical properties can be improved or modified by infiltration, heat treatment, or a secondary mechanical forming operation such as cold re-pressing or powder forging. The article also discusses the effect of the secondary processes on P/M mechanical properties.
