Surface hardness prediction based on cutting parameters in turning of annealed AISI 1020 steel
Authors: Zurita Hurtado Omar Jose , Di Graci Veronica , Capace Maria Cristina
Published: December 2017

La influencia de varios parámetros de corte, velocidad de corte (Vc), velocidad de avance (f), y la profundidad de corte (d) en la dureza superficial desarrollada por torneado en acero AISI 1020 recocido utilizando herramientas de insertos de carburo fue investigada. Se demostró a partir de los resultados medidos que la dureza aumenta con el aumento en todos los parámetros. Se empleó un análisis de varianza (ANOVA) para determinar las contribuciones de cada parámetro estudiado en la variable de respuesta. A partir de los resultados, se encontró que la velocidad de corte tiene el rol más importante en la producción de dureza superficial (69.2 %), seguido de la velocidad de avance (24.4 %), mientras que la profundidad de corte tiene el efecto menor (6.4 %). Finalmente, se propone una ecuación simple, para la predicción de los valores de dureza superficial, que representa los efectos de los parámetros del proceso.
Variation of technological properties of field natural rubber lattices from Hevea brasiliensis clones and natural rubber-based compounds
Authors: Giraldo-Vásquez Diego Hernán , Velásquez-Restrepo Sandra Milena
Published: December 2017

El caucho natural (NR) es un biopolímero ampliamente usado, pero la variabilidad de sus propiedades es una gran desventaja. En este trabajo se estudió la variación del contenido de caucho seco (DRC), total de sólidos (TSC), cenizas, material volátil y nitrógeno de látex de campo de NR, así como de las propiedades mecánicas de compuestos basados en láminas sólidas de NR, evaluando muestras recolectadas durante 6 meses. Las muestras se obtuvieron de tres variedades clonales de Hevea brasiliensis -IAN 710, IAN 873 and FX 3864- cultivadas en una plantación en Antioquia, Colombia. En el cultivo donde se recolectó el látex se monitorearon diariamente pluviosidad, temperatura ambiente, humedad relativa y horas de sol. Se moldearon compuestos emplenado láminas de NR, determinando sus parámetros reométricos y sus propiedades mecánicas. Se encontraron diferencias estadísticamente significativas (p<0.01) para la mayoría de las propiedades evaluadas como efecto de la variedad clonal y la época de recolección. La defoliación fue la etapa fenológica que presentó la mayor influencia sobre las propiedades del NR. Se presentan algunas recomendaciones para controlar la variación de las propiedades del NR durante la fabricación de artículos con este material.
La conciencia de sí como otro. Hacia un re-examen de la tradición psicopatológica
Authors: Roy Jean-Michel
Published: December 2017

La psicopatología contemporánea sufre de una brecha descriptiva (descriptive gap) respecto de la experiencia patológica, y la tradición de la psicopatología contiene un capital descriptivo acumulado que debe ser explotado para la necesaria superación de este déficit. Se argumenta examinando el caso particular de la psicopatología cognitiva de la esquizofrenia y del contenido de la experiencia del delirio de control, mostrando cómo la teoría de Henri Ey, así como la del automatismo mental del siglo xix en la cual tiene sus raíces, contienen herramientas descriptivas importantes para establecer que la experiencia de un delirio de control es esencialmente diferente de la experiencia de una simple ilusión de control.
¿Son los delirios creencias irracionales?
Authors: Cely Flor
Published: December 2017

En este artículo se plantea una discusión con el enfoque doxástico de los delirios. A pesar de que esta línea de análisis ha hecho importantes aportes a la comprensión del fenómeno, tiene dificultades importantes a la hora de aportar un marco explica­tivo completo de los delirios, porque deja por fuera el aspecto total de la experiencia y sigue basándose implícitamente en la idea de que podemos estudiar de manera separada e independiente los aspectos físicos, cognitivos y experienciales de un fenómeno tan complejo. El artículo propone que, más allá de la decisión acerca de si se debe considerar a los delirios como creencias irracionales o no, o de si se pue­de concebirlos como creencias en absoluto, es necesario tener en cuenta la drástica transformación del mundo entero de la experiencia que se da en el sujeto delirante, tal como lo plantea la fenomenología.

Para isso, esse texto se apropria do discurso e das imagens da revista Nin e aborda como a publicação apresenta elementos perversos para a redefinição de identidades, sexualidade, gênero e desejo, não se limitando apenas em apresentar signos engessados sobre esses assuntos, oferecendo uma condição de montagem perversa positiva.
O corpo do/no discurso midiático das dietas: efeitos do novo e da novidade
Authors: Sousa Lucília Maria Abrahão e , Sanches Rodrigo Daniel
Published: December 2017

A pesquisa busca investigar e refletir, na perspectiva teórica da Análise do Discurso (Pêcheux; Orlandi), em interface com pesquisadores das Ciências Sociais, o sujeito e os efeitos de sentido produzidos pelo discurso midiático das dietas e suas supostas novidades. O corpus da pesquisa é composto por revistas e sites que divulgam e promovem as novas dietas. A nossa hipótese é a de que o discurso midiático das novas modalidades de regime afeta a constituição do sujeito e sua relação com o corpo na atualidade. Esse discurso, com uma linguagem sempre ancorada em simbolismos, promete que o novo (a nova dieta, o novo exercício) por si só, é e será sempre o melhor, mesmo que o surgimento de coisas novas ocorra numa velocidade incompatível com a capacidade dos sujeitos de consumi-las e entendê-las em sua totalidade. O discurso midiático do mercado das dietas faz circular sentidos de um corpo-projeto que contrastam com a obsolescência do corpo da realidade. O sujeito é convocado a viver na encruzilhada entre a excelência imposta pelas ferramentas midiáticas e a imperfeição da realidade.

Development and Evaluation of a Thai Learning System on the Web Using Natural Language Processing
Authors: Dansuwan Suyada , Nishina Kikuko , Akahori Kanji , Shimizu Yasutaka
Published: December 2017

The Thai Learning System (TLS) is designed to help learners acquire the Thai word order system. TLS facilitates the lessons on the Web using HyperText Markup Language (HTML) and Perl programming which interfaces with Natural Language Processing (NLP) by means of Prolog. The system introduces an easily understandable presentation of a sentence structure by indicating syntactic trees and case grammar principles. Behind TLS, Prolog analyzes affirmative sentences with Thai phrase structure rules and a computational lexicon, and Perl programming transforms the Prolog results back into a user interface display. The system contains interactive features, pictures, sounds, and informative feedback. Questionnaires and factor analysis were used to evaluate the system. The results of the evaluation showed that TLS has an effective user interface and handles learners' input efficiently.
Interactional Features of Synchronous Computer-Mediated Communication in the Intermediate L2 Class
Authors: Darhower Mark
Published: December 2017

This study explores social interactive features of synchronous computer-mediated communication (CMC)--commonly known as "chat"--as such features unfolded in real time and developed over a nine-week period in two fourth-semester college Spanish classes. The study invoked the Vygotskian sociocultural theoretical framework and employed discourse analysis as a research tool to describe and explain outstanding features of chat room communication. Specific interactional features examined are intersubjectivity, off-task discussion, greetings and leave-takings, identity exploration and role play, humor and sarcasm, and use of the L1 (English). Through these communicative behaviors, learners appropriated the chat room environment, transforming it into a learner-centered discourse community governed by communicative autonomy and the use of language and discourse functions that go beyond those encountered in the typical L2 classroom.

This paper introduces and evaluates new software technologies that significantly ease the reading and writing of Japanese.
Enhancing Higher Order Interpretation Skills for Japanese Reading
Authors: Kitajima Ryu
Published: December 2017

Computer-mediated reading materials can help learners improve their higher order interpretation skills for constructing coherent text representation. As an example, courseware created for improving higher order interpretation skills focuses on anaphoric resolutions and backward inferences, skills particularly important for developing reading skills in Japanese because of the language's tendency to omit referents if they can be reconstructed from the text. Such omissions, because they do not characterize English, present particular difficulties for English-speaking learners of Japanese.
Exploring ESL Learners' Use of Hypermedia Reading Glosses
Authors: Ercetin Gulcan
Published: December 2017

This study explores the types of annotations intermediate and advanced ESL learners preferred to use while they were engaged in reading a hypermedia text. The study also investigated learners' attitudes towards reading in a hypermedia environment. The participants were 84 ESL adult learners enrolled at the Center for English as a Second Language at the University of Arizona. Data were collected through a tracking tool, a reading comprehension test, a questionnaire, and interviews. Quantitative data indicated that the intermediate ESL learners accessed annotations more frequently than those in the advanced group. However, they did not differ in the amount of time they spent on annotations. On the other hand, the advanced learners performed better on the reading comprehension test. Both groups of learners preferred word definitions to pronunciations of words and graphics in order to get information about the text at the word level. However, they preferred videos and graphics to get extra information about the topic. Analysis of the qualitative data revealed that hypermedia reading had a positive impact on the participants' attitudes towards reading on the computer. The participants indicated that the hypermedia environment made reading more enjoyable and comprehensible.
Incidental Development of L2 Proficiency in NS-NNS Email Interactions
Authors: Stockwell Glenn , Harrington Michael
Published: December 2017

Recent research suggests that email can be a powerful motivator for authentic L2 interaction, but little is known about the efficacy of this medium in the development of target language proficiency. The present study addresses this issue by examining email exchanges between university learners of Japanese as a foreign language and native Japanese university students. Of interest is the effect of email interactions on the incidental development L2 syntax and vocabulary as reflected in both quantitative and qualitative measures. Messages sampled at regular intervals over a 5-week collection period indicated a reliable increase in syntactic development as reflected in several measures of structural mastery as well as in qualitative ratings supplied by native speaking raters. There was no evidence of quantitative development for vocabulary, but qualitative ratings did show a small improvement over the collection period. A sharp drop-off was noted between the first and the second samples across all measures, with learner performance then improving steadily till the end of the study. The findings are related to an interactionist account of L2 development that is embedded in the framework of computer-mediated communication (CMC). Issues in research methodology are also discussed.
Achieving social value through construction frameworks: the effect of client attributes
Authors: Awuzie Bankole , Farag Fady , McDermott Peter
Published: December 2017

The UK Public Services (Social Value) Act 2012 mandates public sector construction clients to prioritise the resolution of social challenges through procurement. Accordingly, clients are increasingly committing to delivering on social value through capital expenditure. Construction frameworks have been identified as a means of delivering social value, hence their relatively sudden attractiveness. Yet evidence suggests clients are experiencing varied social value benefits from projects procured through frameworks. The study reported in this paper sought to ascertain the causes of such inconsistency. It investigated the influence of client attributes on the ability of frameworks to deliver on social value. A qualitative case study design was adopted. Interactions between a regional framework and two clients were studied from a project procurement perspective using a viable infrastructure delivery model. Findings revealed that certain client attributes influenced a framework’s ability to achieve optimal social value. Of significance was the ability of the client to express their latent values and their ability to appoint a project manager who will serve as a social value champion. Findings from this study will enlighten clients on their contributions towards successful social value implementation when engaging with a construction framework.
Liquidity from Two Lending Facilities
Authors: Anbil Sriya , Vossmeyer Angela
Published: December 2017

During financial crises, the lender of last resort (LOLR) uses lending facilities to inject critical funding into the banking sector. The facilities need to be designed in such a way that banks are not reluctant to seek assistance due to stigma and that banks with liquidity concerns are attracted rather than those prone to risk-taking and moral hazard incentives. We use an unexpected disclosure that introduced stigma at one of two similar LOLRs during the Great Depression to evaluate whether banks used LOLR assistance to improve their liquidity needs using a novel trivariate model with recursive endogeneity. We find evidence that banks that approached the facility with stigma were less liquid and reduced their position of safe assets in comparison with banks that approached the facility with no stigma. Thus, stigma forced the pool of LOLR borrowers to separate into different groups of banks that ex-post revealed their liquidity preferences. This finding sheds light on why and when banks approach their LOLR.
Housing Bust, Bank Lending & Employment: Evidence from Multimarket Banks
Authors: Glancy David
Published: December 2017

I use geographic variation in bank lending to study how bank real estate losses impacted the supply of credit and employment during the Great Recession. Banks exposed to distressed housing markets cut mortgage and small business lending relative to other banks in the same county. This lending contraction had real eﬀects, as counties whose banks were exposed to adverse shocks in other markets suﬀered employment declines, especially in young ﬁrms. This ﬁnding is robust to instrumenting for bank exposure to housing shocks using shocks in distant markets, exposure based on historical lending, or exposure to markets with inelastic housing supply.
Discourse Analysis on Nationalism Debate Reported in Indian Print Media during Feb-Mar 2016
Authors: Ray Shovana , Singh Jitendra Kumar
Published: December 2017

In the age of progressing information technology, media reporting has evolved in the selection, role portrayal, articulation of the news on the basis of presentation and comprehensibility. Both print and broadcast media have reformulated news reporting pattern considering the current global market, advertising and latent political agendas. Use of particular discourse not just influences mindset; its rhetorical presentation modulates perception on an explicit level. News as a discursive tool transforms the reader’s perception on the topic. In the initial phase of 2016, Indian media extensively reported an incident at Jawaharlal Nehru University (JNU) New Delhi and its effect on the pro- and anti- national sentiments. The reporting was in the context of slogan shouting by a group of students, which was perceived to be anti-national. With due course of time, debates restructured the news into a nation-wide sensation involving various facets, such as, importance of nationalism and patriotism, credibility of the university education, involvement of students from different ideological and identity background (Dalit, Kashmiri Muslim, etc.). In this paper, broad categorisation is being made, namely as, JNU (the university, administration, faculty and its culture), the students (JNUSU president, ASFI members and AVBP members), the state (Judiciary, the ruling party and the opposition parties) and the others (media, celebrities, lawyers and citizens). The present study discusses the impact of news as discourse on the ideological position and activities of news characters (actors) as well as its contextual salience in the national politics.

Published: December 2017

A carne bovina é um alimento importante para a nutrição humana, mas para usufruir dos seus benefícios, ele deve estar seguro do ponto de vista higiênico-sanitário, pois do contrário pode ocasionar infecções alimentares. Assim, este estudo teve como objetivo identificar as condições higiênico-sanitárias dos pontos de venda de carne bovina em feiras livres de Natal (RN), observando-se a concordância com a lei municipal que rege esse tipo de comércio. Trata-se de uma pesquisa do tipo descritiva, onde foi aplicado instrumento do tipo observacional, baseado no Decreto municipal 7676/05. Os resultados demonstraram que 67% das inadequações estão relacionadas ao quesito infraestrutura, seguido de 100% relacionado à higiene do manipulador, 39% de inadequação referente aos equipamentos, 28% aos utensílios, 88% à não utilização de uniforme adequado, 57% relativos ao hábito de gritar e espirrar durante a manipulação de alimentos, 52% relacionado ao uso de barba ou bigode, 76% pela não realização da desosa da carne. Somente 15% dos estabelecimentos possuía na carne o certificado de inspeção federal. Esses resultados sugerem a necessidade de estratégias educacionais para os manipuladores, para que sejam minimizados os riscos de transmissões de doenças relacionadas à carne bovina.
UKRAINIAN COURTS AND THE PROTECTION OF HUMAN RIGHTS
Authors: Muraviov Victor
Published: December 2017

The article is focused on the interaction between the Ukrainian courts of general jurisdiction and the Constitutional Court of Ukraine in the area of the protection of human rights. There is emphasized that their independent functioning does not provide for the efficient protection of individual rights and freedoms and significantly increases the number of the judicial recourses of the Ukrainian citizens to the European Court of Human Rights. Particular attention is paid to the role of the Constitutional Court of Ukraine in the protection of human rights, which combines the functions of the constitutional control and constitutional supervision.
Its activities are focused on the official interpretation on the Constitution of Ukraine. Attention is paid to the list those who may bring the actions before the Constitutional Court, which includes apart from the state bodies the natural and legal persons. The is mentioning of the issues on initiating of proceedings before the Court. Also broadly is analyzed Constitutional Court’ activities concerning the interpretation of the Constitution in the light of the European Convention on Human Rights and other international agreements dealing with the protection of human rights. The article stresses on the contribution of other Ukrainian courts in the affirmation of the constitutional concept of the protection of human rights and freedoms in Ukraine. The majority of resolutions of such highest judicial body in the system of courts of general jurisdiction as the Supreme Court of Ukraine concern the judgments of the European Court of Human Rights. As it is emphasized in the article the independent functioning on the Constitutional Court and the courts of general jurisdiction does not provide for the cooperation between both branches of courts. Courts of general jurisdiction feel free as to the appeal to the Constitutional Court. Even when such appeals are directed to Constitutional Court the decisions of the letter are not binding to the courts of general jurisdiction. Special attention is paid to the introduction of the institute of constitutional complaint and its positive effect on the judicial mechanism of the protection of human rights in Ukraine.
THE PROBLEM OF “FULFILMENT OF THE MINSK AGREEMENTS BY UKRAINE”
Authors: Zadorozhnii Oleksandr
Published: December 2017

The article is devoted to the issue of the violation of the Minsk agreements achieved in the result of the Minsk process by Russia and latter’s interpretation of the agreements as imposing the obligations of fulfilment exclusively on Ukraine. The article dwells on the attempts of the Russian high-rank officials and the representatives of doctrine to accuse Ukraine of non-fulfilling of this document. The author points to specific steps Ukraine has made to implement the provisions of the Minsk agreements (e.g. Ukraine has adopted the Law “On temporarily Order of Local Self-Governance in Particular Districts of Donetsk and Luhansk Oblasts of Ukraine (PDDLO)”) and rebuttals Russia’s weak arguments about Ukraine’s failure to maintain the truce.
Generally, the analysis of the Minsk agreements implementation shows that the purpose of Russia is to de jure turn the conflict into an internal Ukrainian problem; influence decisions of Ukraine both in its internal and foreign policy by means of puppet “DPR” and “LPR”, preferably granting the latter the veto power; destabilize political and social situation in Ukraine, undermine its economy and defence capacity with the help of the above formations. The author arrives at the conclusion that the de-escalation is nominal because of Russia’s failure to cease the illegal actions.

Authors: Aysina R.M.
Published: December 2017

This article analyzes the modern foreign studies on development in the application of various types of cyber technologies used for a wide range of tasks of psychological support for old people. It shows that the majority of foreign authors attribute virtual reality system as the most promising cybertechnology, allowing elder computer users to successfully integrate the existing and acquire new experience through opportunities of controlled changes in sensory, perceptual, cognitive and affective processes. The article considers the spheres of psychological accompaniment of elderly people in which the introduction of computer technologies provides such benefits as prophylaxis and therapy of senile asthenia, cognitive dysfunction, emotional disorders. It reveals, that the question of the effectiveness of cybertechnologies in gerontic psychology’s practice remains open today because of a small number of pilot studies. However, the results are already available.
El nacimiento de la Administración pública regulatoria en Perú
Authors: Vignolo Cueva Orlando
Published: December 2017

La liberalización peruana de inicios de los años noventa, apoyada en el influjo fundamental del principio de subsidiariedad horizontal, produjo no sólo cambios prestacionales y normativos en sectores económicos (con la consecuente reducción del Estado prestador), sino que también supuso la creación de una nueva estructura organizativa administrativa que sirva y se acomode a ciertas características de unas aparentes “nuevas” potestades regulatorias. Desde una versión más estricta y ejecutiva, estas estructuras comportan una adaptación de la policía administrativa y otras competencias administrativas que modulan una intervención sobre estos sectores económicos liberalizados. El presente trabajo intenta desentrañar mitos y certezas jurídicas sobre el surgimiento de esta fórmula organizativa cercana a cumplir veintiséis años de existencia.

Da informática à tecnologia da informação: dependência, reserva de mercado e suas implicações político-econômicas | From informatics to information technology: dependence, market reserve and its political and economic implications
Authors: Araujo Ronaldo Ferreira de , Oliveira Marlene
Published: December 2017

RESUMO Nos rumos da evolução do componente tecnológico na contemporaneidade, a reconhecida era da informação e sua correspondente sociedade da informação já foram também consideradas era da informática e, por sua vez, sociedade da informática. Com o passar do tempo, disciplinas comumente associadas à aplicação da ciência da computação, em conjunto com outros campos de conhecimento, perderam sua alcunha coletiva consagrada, a informática, por um novo termo, o da tecnologia da informação. O artigo discorre sobre o percurso da informática à noção de tecnologia da informação, e reúne, brevemente, elementos que identificam o componente tecnológico, localizados em aspectos políticos, econômicos e sociais do país, para então compreender as implicações dos caminhos tomados. A informática no Brasil é retratada em seus aspectos históricos de dependência e reserva de mercado, abordando-se as implicações políticas dessa postura. As descontinuidades dos programas e governos apontam para uma tímida (ou mesmo inexistente) política nacional de tecnologia da informação no país, e colocam ao centro o aspecto econômico em detrimento dos demais.Palavras-chave: Informática; Tecnologia da Informação; Política Nacional de Informática.ABSTRACT In terms of the evolution of the technological component in the contemporary world, the acknowledged information age and its corresponding information society was also considered as a computer age and, in turn, a computer science society. Over time disciplines commonly associated with the application of Computer Science in conjunction with other fields of knowledge have lost their consecrated collective, computing, for a new term, that of information technology. This paper discusses the course of computing to the notion of information technology and briefly brings together elements that identify the technological component, located in political, economic and social aspects of the country and then understand the implications of the paths taken. Informatics in Brazil is portrayed in its historical aspects of dependence and market reserve, addressing the political implications of this stance. The discontinuities of the programs and governments point to a timid (or even non-existent) national information technology policy in the country, and place the economic aspect at the center at the expense of the others.Keywords: Informatics; Information Technology; National Policy of Informatics.
A Cooperative Communication Model Tailored for Energy Balance in Wireless Sensor Networks
Authors: Rêgo Camila F. , Bezerra Rodrigo R. , Afonseca Ulisses R. , Bordim Jacir L.
Published: December 2017

Wireless Sensor Networks (WSN) are characterized by their capacity of monitoring the environment, gathering and sharing information. Nodes in a WSN usually cooperate in the task of forwarding the sensed data to a sink node for later retrieval and analysis. The success of this task depends on the availability of efficient routes that meet the application requirements. As topology may change overtime, alternatives to improve and maintain network connectivity are highly desired. In this context, Cooperative Communication (CC) emerged as an alternative to improve network connectivity. Despite its benefits, CC-links are known to have higher energy demands as compared to traditional, direct, links. In particular, CC-links require the source node to expend more power than others nodes, shortening their life span. The main contribution of this paper is to propose a new Cooperative Communication model, capable of increasing the energy balance of the CC-links while improving network connectivity. Simulation results show that, compared to other CC schemes, the source node of a Cooperative Communication reduces the amount of expended energy by 68% in the evaluated settings.

Published: December 2017

Objetivos: Determinar el nivel de creencias y prácticas de actividad física y los estilos de vida saludable en el personal administrativo de la Universidad Peruana Cayetano Heredia (UPCH) en el año 2014. Material y métodos: El diseño de estudio fue de tipo descriptivo observacional prospectivo de corte transversal. La población inicial fue de 150 trabajadores administrativos de la UPCH, y por diversos motivos (llenado mal de la encuesta, personal ausente, etc) la población final fue de 100 trabajadores. El instrumento para la recolección de datos fue el cuestionario de prácticas y creencias sobre estilos de vida. Resultados: Se encontró que las prácticas de la actividad física en la población era poca y que sus estilos de vida era poco saludable (43%). Sin embargo, según sus creencias sobre la importancia de la práctica de la actividad física es alta, así como la creencia de tener un estilo de vida saludable (52%). Conclusiones: Con los resultados se concluye que el mayor porcentaje de la población tiene la creencia y los conocimientos sobre la importancia de tener un estilo de vida saludable pero no necesariamente lo practican, esto nos genera las preguntas en relación a los factores que estarían influenciando para que en la práctica no se dé. Se sugiere, asimismo, que la institución promocione los programas orientados a promoción de la actividad física y estilos de vida saludables en el personal administrativo, así como las pausas activas en el centro laboral para prevenir futuras enfermedades y lesiones.

Revenue Sources and Social Media Engagement Among Environmentally Focused Nonprofits
Authors: McCaskill John R. , Harrington James R.
Published: December 2017

This study examines social media efforts among environmentally focused nonprofits. A survey of environmentally focused nonprofits revealed that more than half of these organizations receive government funding. Prior research demonstrates social media is an efficient medium in which to simultaneously communicate with multiple stakeholders. However, stakeholder engagement is likely tied with the need to raise funds. From that basis, we discuss social media use among nonprofits and develop hypotheses about differences in social media use among organizations receiving government funds and those not receiving government funds. Our hypotheses are rooted in resource dependency theory (RDT) and dialogic communication theory (DCT). We test our hypotheses on data from environmentally focused nonprofits by comparing the levels of social media engagement with varying levels of their total funding provided by government grants to determine if there is a correlation with the level of public engagement via social media. We find the level of engagement on the social media site Facebook is lower for government-funded environmental nonprofits than privately funded ones. The findings of reduced social media engagement and the dependence upon government funding versus private funding supports the precepts of resource dependency theory.

A imigração é um fenômeno social que tem adquirido contornos dramáticos na sociedade contemporânea, visto que em muitos casos tem sido impulsionada por situações adversas nos países de origem. Este estudo teve como objetivo analisar as dificuldades e os desafios enfrentados por empresa localizada no Sul do Brasil, a partir da contratação de imigrantes haitianos. Os procedimentos metodológicos se inscrevem naqueles prescritos pela pesquisa qualitativa, visto que se prendeu a evidências mais subjetivas, captadas por entrevistas e pela observação. Para compreender a inserção de imigrantes haitianos em ambiente organizacional, fez-se uso do estudo de caso único, analisando a questão em uma empresa do Sul do Brasil. Foi possível constatar, dentre as principais dificuldades enfrentadas pela empresa estudada, a falta de política de gestão da diversidade, bem como foram captadas dificuldades de comunicação, de integração e de compreensão de diferentes formas de entender e executar o trabalho entre brasileiros e haitianos.

A cluster randomized controlled trial was conducted to change diet, physical activity, smoking and alcohol consumption among participants through funeral societies in the Western Province. Twenty one administrative subdivisions in the Ragama area were randomized into intervention and control groups. Ten administrative subdivisions in the North Western Province were selected as an additional control group. The primary outcome was change in the proportion of individuals who consumed 5 servings or more of fruits and vegetables per day. The study showed only a modest, not significant increase in the proportion of people consuming 5 servings of fruits and vegetables or more per day. Of the secondary outcomes assessed, their intake of green leaves and mean MET minutes spent on leisure activities increased significantly more in the intervention group than in the control groups, but the differences were small. To effectively reduce non-communicable diseases (NCD) in Sri Lanka, community-based organizations could be utilized to deliver prevention programs.

The conducted researches aimed to analyze modern models and methods of implementation of the comparative approach in property and real estate appraisal, to investigate and evaluate their effectiveness, to suggest ways of further improving the methods of property valuation.

To achieve this aim, the authors carried out a series of computational experiments on a computer. The essence of these experiments was the comparative evaluation of the cost of test properties based on the following methods: expert evaluation, solving systems of linear algebraic equations, based on the normalized distances in the space of pricing factors and the correlation-regression method. An analysis was made of the influence of methods of digitizing the initial data (pricing factors) on the final cost of real estate.

On the basis of the studies, prospective ways and directions for further improvement of the methods of property valuation are determined.

Modern European and Scandinavian countries have advanced very far in the development and application of alternative energy sources. The goal of all modern developments is quality improvement and reducing production costs. The precedent of increasing tariffs for utilities is one of the main problems, so there is a need to create non-volatile, autonomous systems that will be controlled and managed remotely. The creation of combined systems that can operate remotely and independently of direct energy resources will lead to a significant increase in the level of protection from the instability of temperature fluctuations and differences in the electrical network.

The present invention relates to heat engineering, in particular to methods and apparatus for generating heat generated differently from combustion of fuel, and can be used in a heating and hot water supply system for residential and industrial premises, as well as for preheating and improving the rheological properties of oil and petroleum products. The presence of sensors in this system allows to monitor, regulate and signal its status, and also allows to set the necessary parameters

Published: December 2017

Changes that take place in ХХІ century in the European economy cause not only the decrease of the topicality of problems of food safety provision, but condition their global and large-scale character. The question of people provision with food products, overcoming of poverty, economic competition at world markets of food and agricultural raw materials is for today priority for the whole international community. This problematic has different aspects and manifestation forms in different countries, regions, territories. The geography of products provision has an ambiguous character: a loss of products and their high quality is observed in certain regions, whereas other regions suffer from malnutrition and low-quality food products. The important role is plaid there by losses of society from waste of food products and low-quality competition, caused by different socio-political and socio-economic interests of countries and desire to influence the internal life of other countries through influence mechanisms on their food market functioning. In general food resources are enough throughout the world for providing satisfactory nutrition of the whole mankind. But food production it is not always provided where it is needed. Starvation and malnutrition, impoverishment of almost 1/5 of the population of the planet is the main social content of the food crisis. The economic competition at world food and agricultural raw materials markets plays no less important role. World tendencies of the value conjuncture, insufficient attention of state leaders to accumulation of sufficient resources for providing parity in the global economic competition create threats in providing food safety of many countries.
BOOK DESIGN IN UKRAINE IN THE LATE 20TH CENTURY

Published: December 2017

In Ukraine, the breakthrough of the 1980s and 1990s was characterized by book design development as a multi-faceted and indicative phenomenon, since at all times the art immediately reacted to any historical changes and reflected the socio-cultural processes. The purpose of this article is to define and compare special artistic features of the book design in Ukraine in the period of 1980s and 1990s. The article considers special aspects of book design development in the territory of modern Ukraine at the close of the 20th century, examines isolated and correlated artistic features of the Ukrainian book editions of the 1980s and 1990s as two qualitatively different periods, and describes the main characteristics of the relevant book products. Moreover, the leading book masters, whose work reflected specifics of this period and became trademarks of the abovementioned age, are determined. Consequently, book design development in Ukraine in the late 20th century looks rather ambiguous from an artistic point of view. The radical structural and political state reorganization in the early 1990s divided its history in two separate stages and influenced all art spheres without exclusion, including the book art. One of the main significant changes in the book design sphere was a transition from classical forms, which depended on the outdated production technologies in the Soviet era, to the electronic design and active computerization of all operations in the sphere of book production. This new environment influenced the worldview of artists and book designers. Put in other words, the mentioned circumstances influenced the restructuring and reformatting of the entire industry, and strengthened the role of a designer as a co-author of a book. This ensured access to new printing standards and contributed to the development of book publishing industry in Ukraine.
