Authors: Hazar Muhsin , Beyleroglu Malik , Bezci Sakir , Baydar Hacer Ozge , Tingaz Emre Ozan
Published: January 2018

The purpose of this research is to examine the class management profile of secondary school branch teachers working in certain province of Turkey, using some variables. The research group consists of 152 teachers (69 female and 83 male) in the various field of Mathematics (29), Turkish (46), Religion Culture (23), English (31), and Physical Education and Sports (23). The "Classroom Management Profile Scale (SYPÖ)" developed by Kris (1996) and adapted to Turkish by Ekici (2004) was used as the data collection tool in the research. The research was conducted based on both the general and the relational screening models. The SPSS 20.0 package program was used in the analysis of the data. Both T test and one-way ANOVA were used in independent groups to determine whether the gender and subscale of the scale were significantly different according to gender, age, occupation year and field. The results of the research proved that, when the scores of both scales were calculated, the grade management profiles of the teachers were not statistically different according to the considered variables.
Achieving the International Benchmarks for Adult Literacy in Nigeria : Post 2015 Challenges and Prospects
Authors: Olojede Adeshina Abideen
Published: January 2018

The story of Adult education in Nigeria is not complete without the activities of itinerant Islamic scholars and traders dating as far back as the 14th century. The Methodist mission, the Church Missionary Society (C.M.S) and other Christian churches pioneered what can be termed as “modern literacy” in Nigeria. The major difference between the activities of Islamic missionaries and Christian missionaries is the acceptance of western education in the south and its rejection in the north. Despite this early involvement in literacy activities, illiteracy still persists in Nigeria. Literacy developments efforts in Nigeria include collaboration with UNESCO in the establishment of an Adult Literacy Institute in Ibadan. In 1965, the University of Ibadan started the training of professional adult educators. Other initiatives include pre-primary education, primary education, the first three years of secondary education (JSS), and literacy for adolescents, adults and women’s education. To help improve literacy development situation, the International Community on Education has put forward a 12 points benchmark on literacy delivery. With the current rate of illiteracy and the fact that the deadline of 2015 which was earlier scheduled for halving the illiterates population could not be met, the credibility of the government activities, most especially in the area of funding, commitment, programmes, strategies and the institutions established on the success or otherwise on the benchmarks as far as Nigeria is concerned has been called into question. Using relevant literature on the topic and personal experience of the researcher, this paper is written, to access Nigeria’s performance in the realization of these benchmarks. However, it established the problems and offers possible recommendations that if applied, would put the country on track again as post 2015 literacy development strategy.
A Cryptography-Based System for Offline Collection and Verification of Tax Revenue by County Governments in Kenya
Authors: Mandala Nebert , Wanga Carlton , Aduda Josiah
Published: January 2018

In the current setting of county governments in Kenya, efficient tax collection is highly dependent on validation of payment documents. This has led to challenges due to the fact that revenue collection has traditionally employed paper-based collection receipts. The research targets to address the challenges of validation of payment receipts in offline revenue collection systems. It supports automation attempts that have been made through the introduction of electronic mobile point of sale terminals. The solution is based on providing an offline model that supports the distributed nature of payment stations. This approach focuses on using cryptography-based techniques to enable offline validation of receipts even in cases of unreliable network connectivity. The objective is to provide a solution that affords ease of both revenue collections for the county governments and payments for the citizenry while stopping revenue leakages, ensuring reliable verification of payment receipts, thus maximising of revenue collection by providing reliable accounting reports. The research provides a reliable revenue collection system that enables offline receipting and verification of payment receipts in integrated mobile point of sale terminals. The solution presented has successfully been implemented and tested in one of the County Governments in Kenya.

Entrepreneurship has impacts on countries, generating jobs and socioeconomic development. In Mexico, from the 1980s, Higher Education Institutions develop entrepreneurship and self-employment promotion programs, to promote entrepreneurial philosophy among their students. In the State of Veracruz, since 2015 the Higher Technological Institute of Zongolica has developed the Social Entrepreneur and Self-Employment (SES) program. The objective of this research is to conduct a study of the perception of university entrepreneurs on the impact of the SES school program on their companies, in the municipality of Tehuipango, Veracruz. For which a questionnaire was designed, applied and validated to a population of 32 graduates of the entrepreneur program. It is concluded that the respondents agree with being entrepreneurs, consider having influenced socioeconomically in their municipality and perceive that the social entrepreneur and self-employment program influenced their level of entrepreneurship. Finally, it was identified the need to create a program of accompaniment to companies, as support so that they continue operating in the market.

Labor Unrest in the Ready-Made Garment Industry of Bangladesh : Causes and Consequences
Authors: Choudhury Sabbrina , Rahman Md. Habibur
Published: January 2018

Labor unrest is a very recurrent circumstance in the garment’s industry of Bangladesh. Violent protest and agitation by workers has become a common feature in garment’s industry. So take into account, we examine the main causes and consequences behind the labor unrest of Ready-Made Garment (RMG) industry in Bangladesh. Data for the study was collected from different garment factories of Dhaka, Ashulia, Tongi, Mirpur, Mohakhali, Gazipur, Narayangang and Savar. Face to face interview and questionnaire method have been used for collecting data of this study. The findings show that the low wage and long working hour are the main causes of labor unrest in the RMG industry of Bangladesh that, in turn, create job dissatisfaction. If the policy makers of RMG industry consider these causes and consequences and take required steps to overcome these problems, the labor unrest in garment industry will be eliminated. Additionally, we identify future research areas that provide scholars opportunities to push theoretical boundaries and offer further insights into the labor unrest
The Function of Prophetic Forthtelling in Roho Christianity
Authors: Bariu Richard Mutura
Published: January 2018

This paper examines the forms and function of prophecy in Roho (Spirit-led) Christianity in Africa. It seeks to situate this function within the rubric of biblical prophecy. It takes seriously their beliefs and theological reasoning that informs their practice. We look at forms of biblical prophecy that generally serve as their guiding principle, namely: foretelling and forthtelling. The literature available on Roho Christianity largely focuses on the historical, sociological, and anthropological aspects of this brand of Christianity. Majority of scholars have paid attention to their origins, rituals, and interaction with the larger society. While this is important, there is very little attention given to one of their principal characteristics--an active prophetic ministry. This paper seeks to satisfy the following seven objectives. Firstly, we look at the prophetic role of the church in African society. Secondly, we try to establish the nexus between prophecy and salvation in Roho Christianity. Thirdly, we look at the forthtelling character and function of Jewish prophecy. Fourthly, we look at prophecy as a community constitution in Roho churches. Fifthly, we assess how prophecy acts as group ritual for identity maintenance. Sixthly, we examine ways in which prophecy acts as symbolic Christian ethics. Finally, we explore how prophetic forthtelling enhances socioeconomic support among Roho churches. In order to achieve the foregoing, we look at concepts common to Roho Christianity in an attempt to draw conclusions about the concept and nature of prophecy in Roho churches and convictions connected with them.

Published: January 2018

The objective of this article is to define what are the factors that prevent achieving a high sense of belonging in current students and graduates of a private university. The sense of belonging impacts on the level of participation of the activities triggered by the university as well as philanthropic strategies that seek to support those who need it most. To carry out this study, group sessions were held with graduates and current students. The latter were also given a survey to know their current perception of belonging and desire to participate in what promotes their university for which the result is that 94% of students would support philanthropic initiatives. On the other hand, the graduates comment that there is a lack of better communication to know what is happening in their alma mater and also to design linking models to strengthen current ties.
Etalement Urbain Et Tensions Foncieres Dans Les Villages Peripheriques De Daloa (Centre-Ouest, Cote d’Ivoire)
Authors: Charles Gouamene Didier , Raphael Oura Kouadio , Sahoti Ouattara
Published: January 2018

The city of Daloa, located in the Ivorian west-centre, is experiencing a rapid spatial growth in recent years due to the acceleration of urbanization. This phenomenon, which should logically constitute an opportunity, because of the consumer market that it represents for the peri-urban villages, is becoming one of the causes of the tensions, then weakening social cohesion. The current urban dynamics cause the problem of space occupation by buildings and the destruction of natural and land resources around the city. Faced with this urban sprawl, which is increasingly aggressive and capable of swallowing up all the surrounding rural areas, the village communities express their concern over the transformation of their regions. In this framework, where the fear of the future has settled in the countryside and where land has become a major issue, the resulting competition for land is more than ever strengthened. This has resulted in land tensions that undermine their resilience faced with the scale of urbanization. The study, which is based on the dual quantitative and qualitative approach, aims to understand both the link between land tensions and urban spread and the perception and strategies developed by rural populations faced with urban pressure.

PENGARUH POST-TREATMENT PLASMA CVD LAPISAN DIAMOND-LIKE CARBON TERHADAP SIFAT KEKERASAN PERMUKAAN BAJA AISI 410
Authors: Anhar Wahyu , Jamal Nurwahidah , Suprapto Suprapto
Published: January 2018

This study is aimed to determine the effect of post-treatment plasma CVD on diamond-like carbon films of surface hardness AISI 410 steel. Enhancement of surface hardness on AISI 410 can be done with deposition thin layer by plasma CVD, and continued by post-treatment plasma CVD. Mixture of Ar (90%) with CH4 (10%), and He (76%) with CH4 (24%) are used as thin layer material. Deposition parameter of pressure, temperature, and time that been used are 1.6 mbar, 300 °C, and 4 hours, respectively. Furthermore, post-treatment process parameter is used by Ar gas, with pressure of 1 mbar, temperature 300 °C, and variation time of 10, 20, 30 minutes. Surface hardness test is used by Vickers microhardness tester. Cross-section microstructure and chemical compositions are examined by scanning electron microscopy coupled with energy dispersive spectroscopy. Based on surface hardness test, the surface hardness on AISI 410 is increased by post-treatment process. The surface hardness from 232.3 VHN increase to 301.2 VHN is produced by post-treatment of compound Ar-CH4 in 20 minutes. Futhermore, the surface hardness from 1,035.8 VHN increase to 1,743.2 VHN is produced by post-treatment of compound He-CH4 in 30 minutes.

Keywords: Post-treatment, Surface hardness, AISI 410, Ar-CH4, He-CH4

Pragmatismo ético e social: cultura, desenvolvimento e humanismo
Authors: Vogt Carlos
Published: January 2018

Num mundo de economia globalizada, de um pragmatismo financeiro a toda prova, de um finalismo utilitarista sem precedentes, de uma violência urbana e de uma urbanização da violência incomuns cabe ainda a oposição, presente em várias línguas e que remonta à antiguidade clássica, entre cidade (civitas, polis) e campo (rus, silva) como topônimos analógicos de civilizado, polido em oposição à rústico e inculto? É possível, apesar dos estudos de Walter Benjamin, continuar a crer que a aliança da cultura e da civilização, que os povos latinos batizaram de humanismo, retomará o seu vigor explicativo e a força de seu poder positivo de transformação, de desenvolvimento e de aperfeiçoamento da sociedade? É possivel continuar a conceder este equilibrio harmonioso, caro aos humanistas, entre os elementos da tradição nacional e os da tradição humana, isto é, entre as culturas nacionais e a universalidade da cultura? É em torno dessas e de outras questões correlatas que se constrói o presente texto.

O Contrato Didático a partir da aplicação de uma sequência didática para o Ensino de Progressão Aritmética
Authors: Souza Carla Maria Pinto , Lima Anna Paula  de Avellar Brito
Published: January 2018

Este artigo resulta de uma dissertação de mestrado que teve por objetivo investigar as negociações do contrato didático, realizadas entre professora e alunos na aplicação de uma sequência didática previamente elaborada para o ensino de Progressão Aritmética (P.A.). A pesquisa foi realizada em quatro etapas: elaboração da sequência didática; análise preliminar; apresentação da proposta à professora; aplicação da sequência. A sequência didática elaborada buscou contemplar as fases propostas por Brousseau na tipologia das Situações Didáticas (situação de ação, formulação, validação e institucionalização), visando possibilitar sua aplicação de acordo com um contrato didático do tipo aproximativo, que é aquele em que a postura ativa do aluno na construção do conhecimento é valorizada. Os resultados apontaram que, embora tivéssemos proposto uma sequência para ser aplicada conforme um contrato didático do tipo aproximativo, negociações, rupturas e renegociações de regras de contrato didático foram feitas ao longo do desenvolvimento da sequência. Acreditamos que essas rupturas das regras estabelecidas foram motivadas por marcas de contrato didático anteriores, ou seja, pelas regras implícitas e explícitas a que professora e alunos estavam habituados.
Sensibilização da audição e educação sonora nos exercícios de limpeza de ouvidos: uma incursão na educação matemática
Authors: Monteiro Júnior Francisco Nairon , Carvalho Washington Luiz Pacheco de
Published: January 2018

O ensino de acústica tem se caracterizado por um modo bancário que pouco contribui para o ideal de formação de cidadãos capazes de entender e atuar na melhoria das paisagens sonoras dos ambientes nos quais convivem. Igualmente distante do mundo da cultura sonora e musical, da tecnologia de áudio e do ambiente acústico, em nada se alinha com o esforço cada vez mais crescente de sensibilização da escuta e da educação sonora, protagonizado pelo educador canadense Prof. Raymond Murray Schafer. No intuito de trazer elementos para a reflexão em torno de como a matemática pode constituir-se enquanto linguagem a concorrer para a educação sonora, desenvolvemos, num modo dialógico problematizador do mundo tecnológico e cultural, uma ação de pesquisa e ensino com licenciandos em matemática da UNEMAT de Barra do Bugres que apontou para a viabilidade da formação de consciências que se coloquem a serviço da melhoria dos ambientes acústicos, na modificação das paisagens nas quais vivemos e que somos corresponsáveis. No presente artigo, apresentamos uma das atividades desenvolvidas durante a pesquisa.
Etnomatemática: metodologia, ferramenta ou, simplesmente, etnorevolução?
Authors: Costa Fernando José Monteiro da
Published: January 2018

A aprendizagem não se constitui num movimento linear, simples e que abrace os alunos do mesmo modo. Antes pelo contrário, o processamento é complexo, por vezes, pouco significativo e, quase sempre, desencorajante em algumas disciplinas, como é o caso da matemática. A etnomatemática aparece como uma espécie de porto de abrigo, em relação a uma multidão de alunos que, provavelmente, não tendo dificuldades cognitivas, encontram na matemática uma aridez de pensamento e de práticas escolares. A ancoragem dos novos conhecimentos é uma matéria importante para o processo de ensino e aprendizagem, sendo indispensável que uma norma inclusiva seja o chapéu para todo o universo da aquisição de conhecimentos e de saberes explícitos.

O Hino às Matemáticas nos Cantos de Maldoror, de Lautréamon
Authors: Fontes Joaquim Brasil
Published: January 2018

Impressos em 1869, em Bruxelas, Os Cantos de Maldoror não circulariam durante a vida do seu autor, nascido em Montevidéu e morto aos vinte e quatro anos de idade numa Paris sitiada pelo exército prussiano: seriam lidos e comentados, durante a belle époque, apenas por pequenos grupos de simbolistas belgas e de decadentistas franceses. Redescobertos pelos surrealistas durante a segunda guerra mundial, os Cantos se transformariam, entretanto, rapidamente, numa das chaves para a compreensão da nossa modernidade e são hoje considerados como uma das realizações mais radicais da escrita da crueldade, depois de Sade e antes de Artaud.
Desfiar e fiar a Aritmética da Boneca Emília: práticas no ensino de Matemática na obra de Monteiro Lobato
Authors: Brito Arlete de Jesus , Oliveira Adriel Gonçalves
Published: January 2018

Este artigo objetiva investigar possíveis relações entre história e literatura. Para isso, analisamos como práticas de ensino de aritmética se manifestam explicitamente na obra ficcional A Aritmética da Emília, do escritor brasileiro Monteiro Lobato (1882 – 1948), e a que rastros de outras práticas culturais o referido livro pode remeter, com base no contexto de ensino de matemática compreendido entre 1920 e 1940. Para tanto, nossa opção de análise segue a intertextualidade entre alguns documentos da época, como A Aritmética da Emília (1935, 1ª edição; 1939, 2ª edição; 1942, 3ª edição; 1944, 4ª edição), Emília no país da Gramática e Aritmética da Emília (1947); outras obras de Lobato; livros didáticos de aritmética da época; legislação sobre ensino; cartas entre Lobato e Anísio Teixeira; revistas sobre ensino; textos sobre educação daquela época; livros de literatura infantil. Temos por referenciais básicos Luiz Costa Lima e Carlo Guinzburg. A escrita aqui elaborada produz um modo de fazer História a partir de uma fonte ficcional, assumindo uma forma discursiva que se aproxima do modo poético, literário e artístico. Concluímos que A Aritmética da Emília reúne em si contradições filosóficas e pedagógicas daquela época, confrontando a tradição didática do ensino conservador com o movimento renovador da Escola Nova, oscilando o caráter inovador de sua proposta pedagógica e recaindo nas práticas professorais de sua contemporaneidade.
História, Literatura e Ficção na Educação Matemática: aproximações com as ideias de Hayden White
Authors: Cury Fernando Guedes , Silva Heloisa
Published: January 2018

Este ensaio apresenta considerações sobre a elaboração do discurso historiográfico narrativo apoiado em técnicas literárias e ficcionais como forma de interpretação nas pesquisas históricas. Concentra-se, como suporte teórico, nas ideias de Hayden White que, há algumas décadas, propôs um debate sobre a natureza do conhecimento histórico contrapondo narrativa, pensamento literário e pensamento científico, indicando ser a história, um artefato verbal, produto de um tipo especial de uso da linguagem, produtora de um conhecimento específico. São apresentados os tipos gerais de tropos identificados pela teoria retórica neoclássica na qual White se apoia – metáfora, metonímia, sinédoque e ironia – que fornecem uma classificação dos ti­pos de discursos históricos e permitem ver as maneiras pelas quais o discurso histórico se parece com ou converge para uma narrativa ficcional. São apontados os principais argumentos deste autor frente às críticas sobre a excessiva relatividade do conhecimento histórico na sua teoria: os sistemas de produção de significados compartilhados por historiografia, literatura e ficção são todos extraídos da experiência histórica de um povo, um grupo, uma cultura. Por fim, são apresentados dois trabalhos no campo da História da Educação Matemática que se valeram da literatura e da ficção para a construção de narrativas que objetivam a produção de conhecimentos acerca da formação de professores e da educação matemática no Brasil.

What is the industrial and technical heritage? Understand it to preserve it = ¿Qué es el patrimonio industrial y técnico? Entenderlo para conservarlo
Authors: Pérez Martín José Luis Javier , Arés Osset María Elena
Published: January 2018

The concept of cultural heritage is subject to a continuous evolution process. This is due to the perceptual modification of an increasingly sensitized society, involved by a changing environment but situated in front of this cultural heritage permanently. Expiry, as perception, incites us to preserve in some way all that time turns into past, since we have been active objects of its existence. The denominated Industrial Heritage is one of the aspects resulting from that social evolution, incorporated to named "Emerging Heritages". Its conservation management needs the previous understanding, so this article is dedicated.ResumenEl concepto de patrimonio cultural, está sometido a un proceso de evolución continua, debido a la modificación perceptual de una sociedad, cada vez más sensibilizada, ante un entorno cambiante que le sitúa frente a sí misma de manera permanente. La caducidad, como percepción, incita a conservar de alguna manera todo aquello que el tiempo convierte en pasado, y que hemos sido objetos activos de su existencia. El denominado patrimonio Industrial es uno de los aspectos resultante de esa evolución social, incorporado a lo que se ha dado en denominar: “Patrimonios emergentes”; la gestión de su conservación precisa de su comprensión, y a ello dedicaremos este artículo.
Integrated project delivery, an alternative to the usual form of construction work in Spain = Métodos colaborativos, un cambio para la construcción en España
Authors: Álvarez Miguel Ángel , Bucero Alfonso , Pampliega Carlos J.
Published: January 2018

The productivity of the construction sector in Spain is very low, as compared to other economic sectors, as with other countries in our environment. It takes us to a deep reflection on whether we are doing things right and what improvements can we introduce to increase production. These improvements must necessarily be technological and methodological, since there is a good training of the equipment both at the managerial level, as well as at the technical and in most of the labour levels, it is to exploit the full potential of new IT tools, especially Building Information Modelling (BIM) and the new methodologies that, from the industry, look for greater efficiency of the process and the elimination of all type of losses, like Lean Construction. A change of mentality, necessary to rethink the way of work in which we have been working for so many centuries, as the only possible paradigm, to replace confrontation as a way of producing construction through collaboration between all the agents involved in the work. We will speak in this article about Integrated Project Delivery (IPD), as one of the Lean methodologies that enable a profound improvement, we will see its definition, its essential components, and how it application can positively influence the construction process in Spain as it has already demonstrated in others.ResumenLa productividad del sector de la construcción en España es muy baja, tanto comparativamente con otros sectores económicos, como con la de otros países de nuestro entorno. Se hace necesaria una profunda reflexión sobre si estamos haciendo bien las cosas y qué mejoras podemos introducir para incrementar la producción. Estas mejoras han de ser necesariamente tecnológicas y metodológicas, ya que existe una buena capacitación de los equipos tanto a nivel directivo, como en la escala técnica y en muchos casos en la laboral, es decir, se trata de aprovechar todo el potencial de las nuevas herramientas informáticas, especialmente Building Information Modeling (BIM) y de las nuevas metodologías que, provenientes de la industria, buscan una mayor eficacia del proceso y la eliminación de todo tipo de pérdidas, como Lean Construction. Un cambio de mentalidad necesario, que pasa por replantearnos la forma de trabajo en la que llevamos tantos siglos empeñados, como único paradigma posible, sustituir el enfrentamiento, como forma de producir la construcción, por la colaboración entre todos los agentes intervinientes en la obra. Hablaremos en este artículo de los Métodos Colaborativos en construcción, que en inglés se han denominado Integrated Project Delivery (IPD), como una de las metodologías Lean que posibilitan una profunda mejora, veremos cuál es su definición, componentes esenciales, y cómo su aplicación puede incidir positivamente en el proceso constructivo de nuestro país al igual que ya lo ha demostrado en otros.
The Molecules and Mechanisms Underlying the Antimicrobial Activity of Escapin, an L–Amino Acid Oxidase from the Ink of Sea Hares
Authors: Derby Charles D. , Gilbert Eric S. , Tai Phang C.
Published: January 2018

Many marine animals use chemicals to defend themselves and their eggs from predators. Beyond their ecologically relevant functions, these chemicals may also have properties that make them beneficial for humans, including with biomedical and industrial applications. For example, some chemical defenses are also powerful antimicrobial or anti-tumor agents with relevance to human health and disease. One such chemical defense, Escapin, an L–amino acid oxidase in the defensive ink of the sea hare Aplysia californica, and related proteins have been investigated for their biomedical properties. This review details our current understanding of Escapin’s antimicrobial activity, including the array of chemicals generated by Escapin’s oxidation of its major substrates, L–lysine and L–arginine, and mechanisms underlying these molecules’ bactericidal and bacteriostatic effects on planktonic cells and the prevention of formation and removal of bacterial biofilms. Models of Escapin’s effects are presented, and future directions are proposed.
Approach for the Development of a Framework for the Identification of Activities of Daily Living Using Mobile Devices’ Sensors
Authors: Pires Ivan Miguel , Garcia Nuno M. , Pombo Nuno , Flórez-Revuelta Francisco , Spinsante Susanna
Published: January 2018

Sensors available on mobile devices allow the automatic identification of Activities of Daily Living (ADL). This paper describes an approach for the creation of a framework for the identification of ADL, taking in account several concepts, including data acquisition, data processing, data fusion, pattern recognition, and machine learning. These concepts can be mapped in a module of the framework, including the use and creation of several algorithms. For the development of a framework that works in several conditions, e.g., without Internet connection, these algorithms should take in account the hardware and software limitations of the mobile devices to run all main tasks locally. The main purpose of this paper is related to the presentation the sensors, algorithms, and architecture of the proposed approach.
The Concepts of Home and Exile in The Mimic Men, a Novel by V.S. Naipaul
Authors: Dizayi Saman Abdulqadir Hussein
Published: January 2018

The aim of this research is to analyze the presence of the concepts of “Exile and Home” in raising the identity crisis in V. S. Naipaul’s novel The Mimic Men (1967). It examines Edward Said’s theoretic contention of exile’s influence in creating identity crisis and in the view of Naipaul’s writing as an attempt to resolve the dilemma of the protagonist Ralph Singh’s identity. The chapter shows Ralph’s responses in endeavoring to form an individual identity while struggling from the burdens of colonial heritage. It is an irony or quiet paradox to apply, as this dissertation does, postcolonial theory to the postcolonial novels, or those novels depicting ex-colonial subject resistance to colonial traditions while living in the very heart of the colonial center, i.e., London; nevertheless, such an application reveals the conflicting sides of the characters’ identity, which has grown in part from attempting to fit in: "The mimic is a contradictory figure who simultaneously reinforces colonial authority and disturbs it".

Snake fruits kernel has high cellulose content thus potential to be an alternative source of carboxylmethylcellulose (CMC) production. However there are several condition that have to be optimized to increase the CMC synthesis which are concentration of  NaOH solution, NaMCA addition, and the reaction temperature based on  the degree of substitution (DS). The aim of this study was to determine the optimum conditions of synthesis CMC from “Salak Pondoh Super” kernel. Some factors that likely influence the synthesis were concentration of  NaOH solution , NaMCA addition, and the reaction temperature based on  the degree of substitution (DS) as the responses. Synthesis of CMC was optimized using completely randomized design. The result then was characterized by several parameters including water content, viscosity, purity, Water Holding Capacity (WHC), Oil Holding Capacity (OHC), lightness, crystallinity, and FT-IR spectra. Optimization was achieved by the use of  15% NaOH solution, 5 gram NaMCA per 5 gram cellulose and reaction temperature of 55ºC. The characteristics of the optimized CMC were DS 0.825, purity 90.86%, water content of 7.16 (% wb), viscosity 3.86 cps, 142.72 yield (% db), WHC 2.37 (g/g), OHC 2.31 (g/g), lightness 78.48, and crystanillity 32.69%. The FT-IR spectra of snake fruit kernel CMC was similar with the CMC Standard.

This study aims to find the important attributes of local and imported apple. A consumer survey was conducted in Java Island representated by four big cities: Malang, Surabaya, Yogyakarta, and Bandung. Three categories of purchasing place at each city are supermarket, fruit stall and traditional market. Accidental sampling was done to choose the samples of consumer. The total respondents interviewed was 240 consumers consisting of 120 for each attribute. The data of apple attributes and purchasing place were analyzed by exploratory factor analysis supported by SPSS software. The result suggests that the important quality attributes of local and imported apples are grouped in each two latent factors namely quality and cultivar. Meanwhile, purchasing place is grouped in one latent factor. All quality attributes of local and imported apples have positive correlation with the apple quality, but there is a different fi nding in which apple flavor of local and imported apples are not the most important attribute that ranked fi rst based on consumer assessment. The factor of apple cultivar always associates with the apple size, both on local and imported apples. Rome Beauty (local apple) and Fuji (imported apple) have greater average size than other cultivars. Thus, these attributes are already attached one another. The factor of purchasing place becomes an important part which accompanies the apple’s quality attributes and is considered by consumers in purchasing apple.
La frontera Chiapas-Guatemala como objeto de estudio de la antropología. Años ochenta del siglo XX
Authors: Gutiérrez Alfonzo Carlos
Published: January 2018

Indago aquí sobre cuáles acepciones de frontera fueron preponderantes en textos de científicos sociales y qué se analizó mediante estas designaciones en la frontera Chiapas-Guatemala, estudiada a partir de los años ochenta del siglo XX, cuando surgió como campo de investigación de la antropología. Seleccioné un número de textos de los años iniciales, con el objetivo de conocer esos primeros planteamientos teórico-metodológicos con los que se exploró esta zona. La línea adoptada me permitió verificar que los investigadores se tomaron libertades al momento de definir los términos teóricos de sus exploraciones. Fueron elegidas dos regiones de estudio (el Soconusco y la Selva Lacandona, que colindan con los departamentos guatemaltecos de San Marcos y Petén), las cuales se iban a ir convirtiendo en polos de atracción para los interesados en conocer esta frontera.

This study has as main objective to analyze the effectiveness of rights in the elderly, based on the Federal Constitution of 1988, the National Policy of the Elderly and the Statute of the Elderly. It is a Bibliographic research, where from a series of scientific documents, we had to report the history of Brazilian population aging together with its legal frameworks and challenges. It was found after the research that there was a considerable growth of the elderly population in Brazil, but this growth must be added to improvements in the quality of life of this age segment, which is not fulfilled in its entirety. It was also shown that many rights were guaranteed in the Federal Constitution of 1988 in the National Policy of the Elderly and in the Statute of the Elderly, but it lacks the will on the part of the state to make them efficient public policies. There is also a lack of knowledge on the part of the elderly and society in general of the rights directed to this population group, which causes another challenge to be overcome.
Spa tourism as a factor of demographic change of spa settlements in Serbia
Authors: Pejic Biljana
Published: January 2018

Spa tourism, as one of the leading forms of tourism in Serbia, is a
significant factor in local and regional socio-economic phenomena and
processes. This paper deals with the impact of spa tourism on local
demographic changes. The analysis includes nine most important spas in
Serbia, in accordance with the achieved tourist traffic. The influence of
tourism in different spas, in the last four decades, on dynamic changes in
their population is taken into account. The paper analyzes the extent to
which the change in the population of spa settlements have taken place
differently from changes at the wider municipal and republic level.
Furthermore, in order to fully understand the importance of tourism for
demographic processes, a change in participation of the employed local
population in the tourism sector was also analyzed. The results show that
tourism has a significant impact on the population of spa resorts. In forty
years that were observed, regardless of general depopulation trend in
Serbia, in most of the analyzed spas there was an increase in the number of
inhabitants, and the highest growth rates were recorded in periods of the
most intensive tourism development. The increase in the number of
inhabitants of spa settlements was accompanied by the increase in the
economic activity of the local residents in the tourism sector.
The Diabetes Gene and Wnt Pathway Effector TCF7L2 Regulates Adipocyte Development and Function

The gene encoding for transcription factor 7-like 2 (TCF7L2) is the strongest type 2 diabetes mellitus (T2DM) candidate gene discovered to date. The TCF7L2 protein is a key transcriptional effector of the Wnt/β-catenin signaling pathway, which is an important developmental pathway that negatively regulates adipogenesis. However, the precise role that TCF7L2 plays in the development and function of adipocytes remains largely unknown. Using a combination of in vitro approaches, we first show that TCF7L2 protein is increased during adipogenesis in 3T3-L1 cells and primary adipocyte stem cells and that TCF7L2 expression is required for the regulation of Wnt signaling during adipogenesis. Inactivation of TCF7L2 protein by removing the high-mobility group (HMG)-box DNA binding domain in mature adipocytes in vivo leads to whole-body glucose intolerance and hepatic insulin resistance. This phenotype is associated with increased subcutaneous adipose tissue mass, adipocyte hypertrophy, and inflammation. Finally, we demonstrate that TCF7L2 mRNA expression is downregulated in humans with impaired glucose tolerance and adipocyte insulin resistance, highlighting the translational potential of these findings. In summary, our data indicate that TCF7L2 has key roles in adipose tissue development and function that may reveal, at least in part, how TCF7L2 contributes to the pathophysiology of T2DM.
