Authors: Wu Tsung-Han , Cheng Chih-Hsien , Lee Chen-Fang , Wu Ting-Jung , Chou Hong-Shiue , Chan Kun-Ming , Lee Wei-Chen
Published: August 2019

Background
The study analyzed the loco-regional therapy outcomes prior to living donor liver transplantation (LDLT), to provide additional information for decision-making regarding therapeutic strategy for hepatocellular carcinoma (HCC) patients.
Methods
A total of 308 consecutive patients undergoing LDLTs for HCC between August 2004 and December 2018 were retrospectively analyzed. Patients subjected to loco-regional therapy prior to LT were grouped and the outcomes were compared.
Results
Overall, HCC recurrence after LDLT were detected in 38 patients (12.3%) during the follow-up period. By the end of the study, 205 patients, 6 of whom with recurrent HCC, were alive. Patients who had radiological imaging beyond the University of California at San Francisco (UCSF) criteria had significant inferior outcomes for both recurrence-free survival (RFS, p = 0.0005) and overall survival (OS, p = 0.0462) despite receiving loco-regional therapy as down-staging intention. Moreover, patients with profound tumor necrosis (TN) had a superior RFS at 3 and 5 years (97.4% and 93.8%, respectively), compared with others.
Conclusion
LDLT gains a satisfactory result based on the expanded UCSF criteria for HCC. However, the loco-regional therapy prior to LDLT does not seem to provide benefit unless a profound TN is noted.
YouTube as a Learning Media to Improve the Student’s Speaking Ability in 21st Century
Authors: Sari Yuli Nurmala , Margana Margana
Published: August 2019

The development of students' skills, especially in speaking, is considered important to get more attention because speaking skill is included as one of the productive skills that requires a lot of practice rather than only learning the theory. In mastering speaking skill, it is regarded necessary to not only understand what others are talking about but also to respond and communicate effectively with others. Thus, a maximum use of instructional media, especially YouTube, is considered necessary in enhancing the development of students’ speaking skill as a crucial capability to be possessed in the 21st century. The purpose of this study is mainly to describe YouTube's maximum use in terms of practice as well as disclose the benefits of using YouTube as a media learning.
Many-body chaos near a thermal phase transition
Authors: Schuckert Alexander , Knap Michael
Published: August 2019

We study many-body chaos in a (2+1)D relativistic scalar field theory
at high temperatures in the classical statistical approximation, which
captures the quantum critical regime and the thermal phase transition
from an ordered to a disordered phase. We evaluate out-of-time ordered
correlation functions (OTOCs) and find that the associated Lyapunov
exponent increases linearly with temperature in the quantum critical
regime, and approaches the non-interacting limit algebraically in terms
of a fluctuation parameter. OTOCs spread ballistically in all regimes,
also at the thermal phase transition, where the butterfly velocity is
maximal. Our work contributes to the understanding of the relation
between quantum and classical many-body chaos and our method can be
applied to other field theories dominated by classical modes at long
wavelengths.

iSulfoTyr-PseAAC: Identify Tyrosine Sulfation Sites by Incorporating Statistical Moments via Chou’s 5-steps Rule and Pseudo Components
Authors: Barukab Omar , Khan Yaser Daanial , Khan Sher Afzal , Chou Kuo-Chen
Published: August 2019

Background:

The amino acid residues, in protein, undergo post-translation modification (PTM) during protein synthesis, a process of chemical and physical change in an amino acid that in turn alters behavioral properties of proteins. Tyrosine sulfation is a ubiquitous posttranslational modification which is known to be associated with regulation of various biological functions and pathological processes. Thus its identification is necessary to understand its mechanism. Experimental determination through site-directed mutagenesis and high throughput mass spectrometry is a costly and time taking process, thus, the reliable computational model is required for identification of sulfotyrosine sites.

Methodology:

In this paper, we present a computational model for the prediction of the sulfotyrosine sites named iSulfoTyr-PseAAC in which feature vectors are constructed using statistical moments of protein amino acid sequences and various position/composition relative features. These features are incorporated into PseAAC. The model is validated by jackknife, cross-validation, self-consistency and independent testing.

Results:

Accuracy determined through validation was 93.93% for jackknife test, 95.16% for crossvalidation, 94.3% for self-consistency and 94.3% for independent testing.

Conclusion:

The proposed model has better performance as compared to the existing predictors, however, the accuracy can be improved further, in future, due to increasing number of sulfotyrosine sites in proteins.
Asymmetric Reactions in Water Catalyzed by L-Proline Tethered on Thermoresponsive Ionic Copolymers
Authors: Suzuki Noriyuki , Mizuno Daisuke , Guidote Armando M. , Koyama Shun , Masuyama Yoshiro , Rikukawa Masahiro
Published: August 2019

L-Proline was covalently tethered on thermoresponsive ionic block copolymers that formed
micelles in aqueous solutions. The block copolymers consisted of a poly(N-isopropylacrylamide)
(PNIPAAm) segment and an anionic or cationic polymer segment. These copolymers exhibited lower
critical solution temperature (LCST) behavior at ca. 35-40°C, and achieved thermal stimuli-induced
formation and dissociation of micelles. The copolymer generated micelles in aqueous solution at a
higher temperature, where a catalytic aldol reaction proceeded with high diastereo- and enantioselectivities.
The micelles dissociated at lower temperature to form a clear solution such that the products
could be efficiently extracted from the aqueous reaction mixture. Extraction of the aldol product with
an organic solvent from the aqueous solution of the anionic copolymer was more efficient than from
the nonionic copolymer solution.
Evaluation of Cartilage in the Wrist using Magnetic Resonance Imaging
Authors: Sivak Wesley N. , Imbriglia Joseph E.
Published: August 2019

Wrist pain is a common patient complaint with a myriad of clinical conditions that can
explain the underlying cause. Short of wrist arthroscopy, no technique other than formal wrist arthrotomy
exists for direct examination of the hyaline cartilage coating the articular surfaces of the
carpal bones. Magnetic resonance imaging (MRI) has been proven accurate in evaluating joint surfaces
of large joints such as the shoulder, hip, and knee with articular cartilage surface thickness is
in excess of 1 mm. However, in the carpus the thickness of the cartilage and the contours present
have precluded accurate imaging. Advances in MRI technology over the last several decades are
now making imaging of small joint surfaces, such as the carpus, an area worth revisiting. Herein we
provide a review of these efforts with a specific focus on the evaluation of the wrist.
Scientific Papers and Patents on Substances with Unproven Effects. Part 2
Authors: Jargin Sergei V.
Published: August 2019

:

Several examples are discussed in this review, where substances without proven effects were proposed for practical use within the scope of evidence-based medicines. The following is discussed here: generalizations of the hormesis concept and its use in support of homeopathy; phytoestrogens and soy products potentially having feminizing effects; glycosaminoglycans for the treatment of osteoarthritis and possibilities of their replacement by diet modifications; flavonoids recommended for the treatment of chronic venous insufficiency and varicose veins; acetylcysteine as a mucolytic agent and its questionable efficiency especially by an oral intake; stem cells and cell therapies. In conclusion, placebo therapies can be beneficial and ethically justifiable but it is not a sufficient reason to publish biased information. Importantly, placebo must be devoid of adverse effects, otherwise, it is named pseudo-placebo. Therapeutic methods with unproven effects should be tested in high-quality research shielded from the funding bias. Some issues discussed in this review are not entirely clear, and the arguments provided here can initiate a constructive discussion.
An Un-Supervised Approach for Backorder Prediction Using Deep Autoencoder
Authors: Saraogi Gunjan , Gupta Deepa , Sharma Lavanya , Rana Ajay
Published: August 2019

Background:

Backorders are an accepted abnormality affecting accumulation alternation
and logistics, sales, chump service, and manufacturing, which generally leads to low sales and low
chump satisfaction. A predictive archetypal can analyze which articles are best acceptable to acquaintance
backorders giving the alignment advice and time to adjust, thereby demography accomplishes
to aerate their profit.

Objective:

To address the issue of predicting backorders, this paper has proposed an un-supervised
approach to backorder prediction using Deep Autoencoder.

Methods:

In this paper, artificial intelligence paradigms are researched in order to introduce a predictive
model for the present unbalanced data issues, where the number of products going on
backorder is rare.

Results:

Un-supervised anomaly detection using deep auto encoders has shown better Area under
the Receiver Operating Characteristic and precision-recall curves than supervised classification
techniques employed with resampling techniques for imbalanced data problems.

Conclusion:

We demonstrated that Un-supervised anomaly detection methods specifically deep auto-
encoders can be used to learn a good representation of the data. The method can be used as a predictive
model for inventory management and help to reduce the bullwhip effect, raise customer satisfaction
as well as improve operational management in the organization. This technology is expected
to create the sentient supply chain of the future - able to feel, perceive and react to situations
at an extraordinarily granular level.
Bayesian Spam Detection Framework on Mobile Device
Authors: Yang Yitao , Sun Guozi , Qiu Chengyan
Published: August 2019

Background:

The spam message aimed at mobile devices has become a prevalent activity
in recent years. About 76% of mobile users received spam messages of Ads, fraud messages and
phishing links. It has led to a significant financial loss of 91.5 billion Yuan per year and this problem
will be more severe in the coming future. Although the operators are making much effort against
spam message, the number of spams are increasing day by day.

Aim:

Many schemes designed to detect and filter spam have been proposed in the research area. The
Bayesian classification algorithm is one of the most popular schemes. Most of the spam detection
schemes based on Bayesian are designed for communication providers. The scalability of filter policy
is hard to control because the strict policy might filter the normal messages while some spam
messages would not be detected due to the flexibility in the policy.

Methods:

The current mobile device has a robust computational capability so it can execute complex
jobs. A spam detection framework is designed in the present study.

Results:

It can sniffer the coming messages in mobile device by hooking the Android SMS API, and
send them to the filter module, -which is responsible to filter messages into normal or spam based
on Bayesian classification. This is a light-weight framework of consuming low power, which is suitable
for mobile devices. Extra experiments are conducted to prove their accuracy and efficiency.

Conclusion:

The results showed that it could filter the spam among receiving the messages in realtime
and become more accurate by learning the users' feedback.

Penning ionization (PI) processes for cold Rydberg alkali metal atoms are investigated. Contrary to the reference case of a hydrogen atom, the corresponding autoionization widths demonstrate a sharp dependence (by orders of magnitude) on the orbital quantum numbers of the atoms exposed to long-range dipole-dipole interaction. An important feature of PI is the nontrivial dependence of its efficiency on the size of Rydberg particles. For all types of alkali atoms, the existence of optimal Rydberg pairs has been demonstrated (highly asymmetric configurations of Rydberg pairs), which lead to an explosive intensification (by several orders of magnitude) of the formation of free electrons due to PI processes. This property makes PI an important source of the formation of primary charged particles during the formation of cold Rydberg plasma. The presented numerical data for potassium atomic pairs demonstrate a significant effect of the Förster resonance on the values of PI rate constants.

Optical properties silica - polymeric optical fiber with a core with a diameter of 430 microns and the reflecting cover 70 microns thick from thermoplastic copolymer of a tetraftoretilen with ethylene (Tefzel brand) are experimentally investigated. The polymeric cover is applied on silica fiber with applicator from polimer melt directly on drowing tower. Optical losses of the fiber, a numerical aperture and its dependence on fiber length are measured. It is established that at propagation of light in fiber its noticeable scattering is observed. It is connected with crystallinity of polymeric cover. Distribution of intensity of scattered radiation along an axis of fiber and an indicatrix of dispersion of radiation by a coating are measured. Relative deposits of dispersion and absorption of light in a cover at the general optical losses of fiber are estimated. The possibility of use of optical fibers of this structure in laser medicine is considered.
The Discursive Construction of Gender as Social Identity in Arabic written Discourse
Authors: Hussein Shifaa Hadi
Published: August 2019

Identity is the idiosyncratic features that characterize an individual as being unique. It is the dynamic per formativeness of self through behaviors, acts, clothes and etc.. When such self is shared (by sharing memories, desires, and emotions) with others, it becomes social identity. Such an identity is, thus, changed, transformed, spoke out, acknowledged and never be fixed at any moment of life. The current study aims at studying the discursive construction of social identity in Arabic written discourse. It seeks to ponder the question of what linguistic devices do the Arab writers utilize to identify themselves in discourse and to show sameness and differences between in – and out- groups. To attain the above aim, we hypothesize that Arab writers use scanted discursive and linguistic devices to identify gender in their writing. Accordingly, seven linguistic and discursive components have been chosen to analyze the discourse to unveil the identity of its writer: processes, mood, modality, vocabulary and collocation, pronouns, figurative uses of language, and interdiscursivity. The study comes with some conclusions, the most important of which are: social identity can be traced in Arabic discourse through the construction of in _ and out_ groups with the in- group being victimized by the out-group who is the dominant, a conclusion which clashes with studies of critical discourse analysis, and changes and transformation of identity occur through stages including: attention, interest, solutions and urging by giving commands.
The Socio-Political Effects on Using Puns in Iraqi Arabic Jokes
Authors: Ali Marwah Kareem
Published: August 2019

Jokes can be effective and can achieve various purposes depending on how they are said or written. It is a fact that jokes refer to statements with humorous effect used as a means of entertainment to make people laugh and feel happy. However, jokes can have other socio-political meanings depending on the expressions found in them. This can be achieved through the employment of expressions denoting pun. Additionally, meanings of pun can be expressed in different ways depending on the socio-cultural characteristics of the community. Therefore, this study aimed at defining the socio-political impact of employing pun expressions in Iraqi jokes based on the socio-cultural specificity of the Iraqi community. To conducted such a study, this required using a qualitative method with a critical analysis. The data of this study were represented by (15) jokes written in Iraqi Arabic dialect (Iraqi colloquial language) and translated into English to be understood by those who do not speak Arabic language. Pun expressions were italicized in both source and target texts to be distinguished from other expressions in the joke. The results of this study revealed the influence of socio-political situations on creating jokes in Iraqi society. Moreover, the most notable type of pun used in Iraqi jokes was homonymous. This is due to that Iraqis intentionally tend to conceal the real intended meaning by using words that have the same spelling and pronunciation but carry different connotations.
Building a Semantic Health Data Warehouse in the Context of Clinical Trials: Development and Usability Study
Authors: Lelong Romain , Soualmia Lina F , Grosjean Julien , Taalba Mehdi , Darmoni Stéfan J
Published: August 2019

Background

The huge amount of clinical, administrative, and demographic data recorded and maintained by hospitals can be consistently aggregated into health data warehouses with a uniform data model. In 2017, Rouen University Hospital (RUH) initiated the design of a semantic health data warehouse enabling both semantic description and retrieval of health information.

Objective

This study aimed to present a proof of concept of this semantic health data warehouse, based on the data of 250,000 patients from RUH, and to assess its ability to assist health professionals in prescreening eligible patients in a clinical trials context.

Methods

The semantic health data warehouse relies on 3 distinct semantic layers: (1) a terminology and ontology portal, (2) a semantic annotator, and (3) a semantic search engine and NoSQL (not only structured query language) layer to enhance data access performances. The system adopts an entity-centered vision that provides generic search capabilities able to express data requirements in terms of the whole set of interconnected conceptual entities that compose health information.

Results

We assessed the ability of the system to assist the search for 95 inclusion and exclusion criteria originating from 5 randomly chosen clinical trials from RUH. The system succeeded in fully automating 39% (29/74) of the criteria and was efficiently used as a prescreening tool for 73% (54/74) of them. Furthermore, the targeted sources of information and the search engine–related or data-related limitations that could explain the results for each criterion were also observed.

Conclusions

The entity-centered vision contrasts with the usual patient-centered vision adopted by existing systems. It enables more genericity in the information retrieval process. It also allows to fully exploit the semantic description of health information. Despite their semantic annotation, searching within clinical narratives remained the major challenge of the system. A finer annotation of the clinical texts and the addition of specific functionalities would significantly improve the results. The semantic aspect of the system combined with its generic entity-centered vision enables the processing of a large range of clinical questions. However, an important part of health information remains in clinical narratives, and we are currently investigating novel approaches (deep learning) to enhance the semantic annotation of those unstructured data.

Conhecido como a savana brasileira, o Cerrado é considerado o mais rico do mundo em biodiversidade, por não possuir uma fisionomia única e uniforme. Este bioma apresenta extrema abundância de espécies nativas, contudo inúmeras espécies de plantas e animais correm risco de extinção, como no caso do lobo-guará (Chrysocyon brachyurus), maior canídeo da América do Sul. Segundo a The IUCN Red List, o lobo-guará está classificado como quase ameaçada (Near Threatened), tendo como principais ameaças a fragmentação de seu habitat natural, atropelamentos, perda de variabilidade genética e introdução de espécies exóticas no seu habitat. A espécie fica alarmada à aproximação humana apresentando reações típicas de animal territorialista. Para que não entre em extinção, é necessário ampliar o conhecimento sobre o lobo-guará, permitindo sua preservação na natureza e manutenção em cativeiro, visando o bem-estar desse animal. O enriquecimento ambiental é uma das soluções para combater o stress de animais em cativeiro, assegurando um ambiente que lhes proporcionem tranquilidade e segurança. Este trabalho teve o objetivo de analisar os comportamentos da espécie Chrysocyon brachyurus em parques zoológicos, considerando seus recintos com o intuito de uma proposta de enriquecimento ambiental. Foram realizadas observações em quatro zoológicos da região do Estado de São Paulo com ênfase na relação entre comportamento e recinto. Foram observados dez lobos, havendo diferenças nas frequências comportamentais com comportamentos territorialistas em taxas mais altas. Os dados foram analisados e comparados segundo a literatura. Para o tratamento dos dados, foi utilizada estatística descritiva como média, desvio padrão, erro padrão e coeficiente de variação. Para mostrar o efeito que o recinto exerce sobre o comportamento dos animais, foi utilizado o tamanho de efeito do Cohen’s (effect size, Cohen’s D). A partir dos dados analisados, é possível observar que os recintos podem afetar alguns comportamentos dos lobos-guará. Logo, esse trabalho sugeriu um recinto adequado para os lobos, possuindo características de enriquecimento social, alimentar, cognitivo, físico, sensorial, além da fundação estrutural. De forma que garanta a preservação e o bem-estar da espécie.
Conditional work statistics of quantum measurements
Authors: Mohammady M. Hamed , Romito Alessandro
Published: August 2019

In this paper we introduce a definition for conditional energy changes due to general quantum measurements, as the change in the conditional energy evaluated before, and after, the measurement process. By imposing minimal physical requirements on these conditional energies, we show that the most general expression for the conditional energy after the measurement is simply the expected value of the Hamiltonian given the post-measurement state. Conversely, the conditional energy before the measurement process is shown to be given by the real component of the weak value of the Hamiltonian. Our definition generalises well-known notions of distributions of internal energy change, such as that given by stochastic thermodynamics. By determining the conditional energy change of both system and measurement apparatus, we obtain the full conditional work statistics of quantum measurements, and show that this vanishes for all measurement outcomes if the measurement process conserves the total energy. Additionally, by incorporating the measurement process within a cyclic heat engine, we quantify the non-recoverable work due to measurements. This is shown to always be non-negative, thus satisfying the second law, and will be independent of the apparatus specifics for two classes of projective measurements.
Semi-device-independent certification of indefinite causal order
Authors: Bavaresco Jessica , Araújo Mateus , Brukner Časlav , Quintino Marco Túlio
Published: August 2019

When transforming pairs of independent quantum operations according to the fundamental rules of quantum theory, an intriguing phenomenon emerges: some such higher-order operations may act on the input operations in an indefinite causal order. Recently, the formalism of process matrices has been developed to investigate these noncausal properties of higher-order operations. This formalism predicts, in principle, statistics that ensure indefinite causal order even in a device-independent scenario, where the involved operations are not characterised. Nevertheless, all physical implementations of process matrices proposed so far require full characterisation of the involved operations in order to certify such phenomena. Here we consider a semi-device-independent scenario, which does not require all operations to be characterised. We introduce a framework for certifying noncausal properties of process matrices in this intermediate regime and use it to analyse the quantum switch, a well-known higher-order operation, to show that, although it can only lead to causal statistics in a device-independent scenario, it can exhibit noncausal properties in semi-device-independent scenarios. This proves that the quantum switch generates stronger noncausal correlations than it was previously known.
Giro dinámico y lógica de la investigación científica
Authors: Murillo-Corchado María Victoria , Nepomuceno-Fernández Ángel
Published: August 2019

Para presentar la incidencia del giro dinámico en la lógica de la investigación científica, en este artículo comenzamos con una sección que trata de los juegos lógicos como desencadenantes de este giro dinámico en la lógica contemporánea, junto con el programa de dinámica lógica de la información y la interacción. Sucintamente presentamos las principales características de la lógica favorable a la independencia y la semántica juego-teórica (IF-logic y GTS, respectivamente, en Hintikka y Sandu 1997), de la lógica dialógica (Redmond y Fontaine 2011), así como los elementos esenciales de dicho programa. Si bien a partir de cualquiera de estos puntos de vista se cuenta con un elenco de herramientas lógicas para abordar cuestiones más claramente epistemológicas, destacamos el papel de la lógica epistémica dinámica (LED), a la que dedicamos la siguiente sección. Sigue otra en la que entramos en los estudios lógicos de la abducción como uno de los problemas fundamentales de la epistemología contemporánea y, en una nueva sección, en términos de los constructos teóricos de las secciones precedentes, presentamos y explicamos un fenómeno surgido en el campo de la lingüística, el caso del descubrimiento de la lengua amazónica pirahã, que debería ser considerado una anomalía en el marco de la teoría chomskiana.
Technological mercantilism and technological colonization: new challenges for Russia

Published: August 2019

An assessment is made of the prospects for Russia’s perception of advanced technological knowledge borrowed in industrialized countries for technological modernization of enterprises in the real sector of the economy. A review of the episodes of 2017–2019, which suggest that the policy of technological mercantelism is becoming more and more distinct and rigid forms, is presented. Especially frankly, it manifests itself in the example of relations between the USA and China, the USA and Russia.

The history of the formation and evolution of technological protectionism, starting from the seventeenth century, is considered to the present day. It has been suggested that technological colonization, which is carried out by the technology-leading countries with respect to the countries of the technological periphery, is the highest evolutionary form of technological protectionism.

O jatobá (Hymenaea courbaril L.), pertencente à família Fabaceae, é uma planta arbórea que possui potencial madeireiro, alimentar e medicinal. Este estudo teve por objetivo realizar um levantamento etnobotânico do jatobá (Hymenaea courbaril) na região norte do Estado de Mato Grosso, Brasil. Dados socioeconômicos e etnobotânicos foram obtidos a partir de perguntas fechadas e abertas com os entrevistados. Os resultados foram avaliados quali e quantitativamente. Os entrevistados, em sua maioria, nasceram no Sul do Brasil, mas residem há mais de 20 anos no norte de Mato Grosso, com predominância de agricultores familiares. Os entrevistados relataram conhecer a espécie, principalmente, pelas características das folhas, casca e fruto. A espécie é utilizada nas categorias alimentar, artesanato, ecológica, madeireira, medicinal e tecnológica, totalizando 42 tipos de usos, sendo que destes, 83% foram incluídos na categoria medicinal. As maiores concordâncias de uso entre os entrevistados foram para o tratamento de gripe (CUPc=68), anemia (CUPc=56) e farinha do fruto para alimento (CUPc=48). Os resultados indicam que H. courbaril é uma espécie de uso múltiplo, sendo utilizado, principalmente, como medicinal e que os entrevistados possuem amplo conhecimento sobre a espécie nativa da Amazônia Brasileira.

Dentre as principais plantas inseridas no semiárido brasileiro, encontra-se a aroeira (Myracrodruon urundeuva Allemão) pertencente à família Anacardiaceae, apresentando importância ecológica e econômica. A fim de entender e verificar tal importância, realizamos um estudo etnobotânico em seis comunidades do semiárido paraibano, utilizando formulários semiestruturados aplicados a populações locais. Registraram-se 1.587 citações de uso (856 citações atuais e 731 potenciais), sendo 985 de usos madeireiros e 602 não madeireiros para M. urundeuva. Destacaram-se as categorias construção e combustível. Mediante os resultados do presente estudo, sugere-se que sejam realizadas pesquisas e monitoramento das populações dessa espécie nas áreas rurais, e com atividades voltadas para o manejo sustentável.
Políticas activas de empleo en España: antecedentes y marco cultural desde el análisis del debate político
Authors: María Belén García-Palma
Published: August 2019

La presente investigación es un análisis de las políticas activas de empleo
en España, que aplica las herramientas y técnicas que ofrece la perspectiva
sociológica. Este análisis permite la consideración analítica del
entorno en el que se desarrollan, a través de las distintas dimensiones
que se dan en las formas de organización social, se entiende como estas
estructuras sociales que rigen en los distintos ámbitos sociales de forma
interconectada y que imprimen su carácter y funcionamiento
El período contemplado en la investigación es el decenio 2003-2013,
dado que la Ley 56/2003, de 16 de diciembre, de Empleo, marcó una
nueva etapa en su regulación. Los principales textos normativos del marco
regulador de las políticas activas de empleo, y la transcripción de los debates que le acompañan para su aprobación en las Cortes Generales (Congreso de los Diputados y Senado), constituyen la materia prima de la que se nutre este trabajo de investigación. Estos documentos oficiales son el producto de la vida institucionalizada de la sociedad. A este material se le ha aplicado un análisis de contenido, desarrollado a través de diversas estrategias de tipo descriptivo, contextual, relacional y conceptual.

El trabajo realizado ha permitido concretar los antecedentes y el marco
cultural del proceso de debate y tramitación del marco normativo de las
políticas activas de empleo. Entre los resultados, cabe destacar la definición
política del contexto socioeconómico y los determinantes inmediatos
para la promoción del marco regulador de las políticas activas de empleo;
así como los aspectos que se posicionan como normas y valores
sociales como por ejemplo, los compromisos que adquieren los trabajadores
desempleados y los poderes públicos en el desarrollo de estas políticas.
Controversias en torno a la terminalidad educativa y la empleabilidad de mujeres destinatarias de programas sociales: virajes de gestión en torno al programa Hacemos Futuro
Authors: María Andrea Voria , María Eugenia Miguez
Published: August 2019

En este artículo nos proponemos indagar las controversias en torno a la
terminalidad educativa y la empleabilidad en programas sociales del Ministerio
de Desarrollo Social de la Nación (MDS), en particular el ex
Programa Ingreso Social con Trabajo –Argentina Trabaja– (PRIST-AT)
(2009-2018) y su línea programática Ellas Hacen (EH) (2013-2018),
unificados desde febrero del 2018 bajo el programa Hacemos Futuro
(HF). El objetivo del artículo consiste en problematizar, desde una perspectiva
de género, la terminalidad educativa y la empleabilidad en las
mujeres destinatarias, especialmente en el “período bisagra” entre el fin
de la gestión kirchnerista y los primeros años de gobierno de la Alianza
Cambiemos.
El corpus de análisis se basó en la revisión de fuentes secundarias (normativa,
informes de gestión y pedidos de informes); fuentes primarias a
partir de entrevistas en profundidad a cuadros intermedios del MDS y el
desarrollo de dos grupos focales con mujeres titulares del ex AT como de
EH, en los distritos de Tigre y San Fernando de la Provincia de Buenos
Aires, durante 2017 y 2018.
Los resultados que hemos, provisoriamente, alcanzado dejan planteadas
una serie de controversias relativas al peso diferencial que adquieren entre
uno y otro programa (AT-EH), como entre una y otra gestión del
MDS, los componentes de terminalidad educativa y empleabilidad sobre
las titulares, y sus implicancias en términos de reconocimiento social,
responsabilidades de cuidado e integridad frente a la problemática de la
violencia de género.
Pendampingan Penulisan Karya Ilmiah Remaja untuk Meningkatkan Kreativitas dan Literasi Siswa di MA Muhammadiyah 1 Malang
Authors: Fatmawati Diani
Published: August 2019

Perkembangan zaman di era Revolusi Industri 4.0 menuntut siswa memiliki kreativitas dan literasi untuk menghadapi tantangan yang ada. Kedua kemampuan ini tidak hanya bisa dikembangkan dalam proses pembelajaran, namun juga dapat dikembangkan dengan adanya keikutsertaan siswa dalam pembuatan Karya Ilmiah Remaja (KIR). Namun pada faktanya, tidak semua sekolah mampu membina siswanya untuk bisa menghasilkan karya ilmiah, seperti halnya pada Madrasah Aliyah (MA) Muhammadiyah 1 Malang. Pengabdian ini bertujuan untuk melakukan pendampingan untuk penulisan karya ilmiah remaja pada siswa MA Muhammadiyah 1 Malang. Subjek pengabdian berjumlah 10 orang yang terdiri dari 4 orang guru dan 6 orang siswa. Kegiatan pengabdian dilaksanakan selama 4 bulan. Instrumen untuk mengambil data terdiri dari soal pilihan ganda, soal essay beserta rubrik penilaian, dan kamera untuk dokumentasi. Hasil pengabdian menunjukkan bahwa pemahaman subyek pengabdian terkait metode ilmiah secara umum cukup tinggi (di atas 50%). Sedangkan kemampuan berpikir kreatif masih cukup rendah yakni 33% pada dua indikator (“dapat diterapkan” dan “keterjangkauan biaya”) meskipun indikator “kemanfaatan” cukup tinggi (83%). Pada aspek kemampuan literasi, mayoritas (83%) subyek pengabdian juga menunjukkan kemampuan pada level paling redah yakni nominal, sedangkan 17% lainnya pada level fungsional. Berdasarkan hasil pengabdian, maka disarankan untuk memberikan pendampingan dengan frekwensi yang lebih intensif kepada siswa MA Muhammadiyah 1 Malang dengan memberikan fokus yang lebih tegas pada berbagai aspek kemampuan yang masih rendah.
