Authors: Sarikarin Tachakun , Suksri Amnart , Wongwuttanasatian Tanakorn
Published: July 2018

The performance of photovoltaic module (PV) situated outdoors suffers from high temperature. When the high temperature of surrounding atmosphere is increased, the generation of electricity power drops rapidly. This paper is concerned with the temperature compensation technique of the cooling PV cell by using the phase change materials (PCMs). PCM used in this research is palm wax with the melting point at 52 °C. We used a stainless steel container that is designed with three types of installation (fin type, groove type and tube type) to cover the surface area for heat exchanger purpose. The heat exchanger is installed at the back of PV cell. The test is conducted for all day (9AM-5PM) under the climatic condition of Khon Kaen, Thailand (latitude, 16° 26’ 20” N and longitude, 102° 49’ 43” E) during winter. It was found that the PV cell that is used PCMs installed container with fin type was able to produce more electric power to an order of 8.178 per cent than the controlled reference module.

Published: July 2018

IT plays an important role in human life and industry in the whole world such as in manufacturing, transporting, medical, tourism and education. However, IT became one of the contributors to the Carbon Dioxide (CO2) emission that cause global warming. To reduce CO2 emissions by IT device, Green IT had been introduced. Green IT is an activity or action that being used and implemented to minimize the harmful of IT devices to the environment. The government of Malaysia had introduced Green IT in Malaysia since 2009. Despite of that, the awareness level of Green IT among Malaysian is still low and empirical study regarding Green IT awareness among academician is still unexplored. This paper study on the awareness regarding Green IT among academicians and administrative staffs in public universities. There were 245 academicians and administrative staffs were involved as respondents. Descriptive statistics had been used in this study. Overall, the finding shows that the level of Green IT awareness among academicians and administrative staffs was at moderate level. Finally, some issues had identified as barriers to the implementation of Green IT in the public universities such as lacking of support from staff, unrealized the existence of Green IT guideline, and lacking of enforcement. Some initiatives should be done to educate people and enhance their awareness about Green IT.

Published: July 2018

What we know about association between social media and media literacy is largely based upon case studies that investigate how teenagers’ behavior in digital environment. Although studies focusing on the level of media literacy skills towards social media have been conducted in recent years, much uncertainty still exists about the relationship between the media literacy skills and the use of social media among teenagers. This study aims to contribute to this growing area of research by exploring the level of media literacy skills and motivations among the teenagers towards social media in urban area. A quantitative descriptive survey research design was used to identify, analyze, and describe the media literacy skills of teenagers towards social media. The purposive sampling method was taken to appropriately select an evenly balanced group of participants. In total, 34 students participated, of which 83% living in the rural-urban fringe area, the intersection area between urban and farming field. It is evidently clear from the findings that the average level of media literacy skills among teenagers in urban area is at medium level. There is a high level of information dimension among teenagers, whereas other dimensions are fractionally less popular. On average, the level of dimensional motivations is medium. Teenagers seem to use social media to support their study and socially engage with friends. The result of this study confirm previous studies that focused on the level of media literacy among teenagers towards social media. Analysis of data shows that teenagers acknowledged the benefits of social media. However, no statistically significant difference between the mean sores of four sets of media literacy skills was evident. Media literacy is maturing, as evidenced by the significant understanding of social media in the digital environment.

Published: July 2018

In activated sludge system, the performance of the process largely depends on the balance between filamentous and floc-forming microorganisms. When the normal balance of these biological communities is disturbed, filamentous microorganisms tend to proliferate, causing various problems to the treatment performances such as sludge bulking. Various approaches have been used to control the proliferation of filamentous microorganisms. However, the approaches led to various drawbacks that eventually worsen the performances of treatment systems. Therefore, this study is aimed to investigate the potential approach using static magnetic field in inhibiting filamentous microorganisms that presence in the sludge bulking. Magnetic field of intensity 88 mT was used. Its exposure on the filamentous microorganisms was investigated in terms of filaments' characteristics such as branching, shape and filaments' location. The analysis indicated that the magnetically exposed activated sludge showed less possibility presence of the filamentous microorganisms compared to unexposed activated sludge.

Authors: Loong Chin Chee , Khun Ma Chau , Yang Tan Jia , Zawawi Awang Abdullah , Omar Wahid
Published: July 2018

External passive confinement has been used as strengthening scheme to rehabilitate existing reinforced concrete buildings. Passive confinement requires a certain lateral dilation of concrete prior to the activation of the confining effect. Applying pre-tensioned force to the confining material can eliminate the needs of such lateral dilation. This paper presents a review on previous studies conducted about pre-tensioned level in confined concrete. A short discussion is done based on the effect of pre-tensioned level to the three regions of stress-strain curve. It was found that pre-tensioned level affects the stress-strain behaviour of confined concrete. Pre-tensioned level that is too high decreases the strain capacity of the confined concrete. This review suggests that there exists an optimum pre-tensioned level for each confining material.

Malay Royal towns in Malaysia are the finest examples evolution of early Malay towns dating from the 16th century. However the identity and characteristic of Malay Royal towns is still unclear and continuously been threatened from tremendous changes due to rapid industrialisation, economic development and urbanisation. The extensive urbanisation and rapid development occurring in most of historical towns have significantly eroded the identity, sense of place and physical attributes of the Malay Royal Town. Besides monuments and sites, the scope of this research also covers all properties which are of historic and cultural significance. This research employs qualitative approach that encompasses of literature review of scholarly articles and reports, in-depth interview and structured observation. Based on the historical and physical evidences that are still exist, 9 historical town that gazated as Malay Royal town will be selected as a preliminary study and 5 historical towns will be selected as study area namely; Anak Bukit, Kota Bharu, Seri Menanti, Klang and Kuala Terengganu. The findings gathered from this research too is deemed a comprehensive understanding of attributes of the royal Malay town and further may help in strengthening the Malaysia history.

Published: July 2018

Many of the present eco-cities are designed and planned with an emphasis on high technology and infrastructure yet the meaning of sustainability itself implies a balance between past and present. Past urban configurations that rise from earlier traditional socio-cultural structures reflect sustainable principles localised to climate and ecology. The aim of this study is to reconstruct urban morphologies be-fore the advent of the automobile in order to analyse and characterise urban forms that are aligned with ecological criteria such as walk-ability, permeability and shade. Three traditional urban center or ‘cores’ in tropical Malaysia which had reigned during the early colo-nial era yet still related sultanate-based polities are mapped in terms of morphologies and these urban ‘core’ configurations were esti-mated and composed according to historical documents and evidences . These urban patterns are then discussed with regards to the present principles and criteria of green urbanism. The reconstructed and mapped urban cores are discussed in relation to green urban-ism principles and criteria, namely, based on global sustainable standards namely the LEED ND (Leadership in Energy and Environ-mental Design) version 4 neighbourhood rating system. The findings from this study suggest the contextualization of sustainable criteria according to climate and postulate the differences between traditional urban morphologies that can further regionalism principles of current green urbanism and further contextualise key principles in international standards on urbanism.

Published: July 2018

This study aims to investigate the relationship between the water quality index (WQI) for irrigation purposes and four independent climate variables. Our case study was conducted on the Euphrates River within Karbala city, Iraq over the period between 2008 to 2016. The Bhar-gava WQI was calculated using nine physicochemical parameters, the electrical conductivity (EC), total dissolved solids, turbidity, pH, and calcium, magnesium, sodium, chloride and sulfate levels. The Bhragava WQI classified the Euphrates river as generally "good". Artificial neural network (ANN) and non-linear regression models were developed and used to forecast the relationship between the WQI and four independent climate variables (temperature, relative humidity, and rainfall depth and sunshine duration). The non-linear regression model was adopted to predicate the WQI because the coefficient of determination and minimum error value were better than those obtained with the ANN model. The non-linear model matched the calculated Bhargava WQI values and recorded meteorological data with a coefficient of determination (R2) = 78.2 and standard error = 2.1.

This paper presents learning analytics as a mean to improve students’ learning. Most learning analytics tools are developed by in-house individual educational institutions to meet the specific needs of their students. Learning analytics is defined as a way to measure, collect, analyse and report data about learners and their context, for the purpose of understanding and optimizing learning. The paper concludes by highlighting framework of learning analytics in order to improve personalised learning. In addition, it is an endeavour to define the characterising features that represents the relationship between learning analytics and personalised learning environment. The paper proposes that learning analytics is dependent on personalised approach for both educators and students. From a learning perspective, students can be supported with specific learning process and reflection visualisation that compares their respective performances to the overall performance of a course. Furthermore, the learners may be provided with personalised recommendations for suitable learning resources, learning paths, or peer students through recommending system. The paper’s contribution to knowledge is in considering personalised learning within the context framework of learning analytics.

Leukocyte adhesion deficiency-I caused by a novel mutation in ITGB2 presenting with pyoderma gangrenosum
Authors: Haynes Alison , O’Keefe Andrew , Dancey Paul , Ohson Kamal , Turner Lesley , Chard Marisa
Published: July 2018

Background: Leukocyte adhesion deficiency (LAD) syndromes are primary immunodeficiency disorders caused by defects in adhesion molecules on leukocytes resulting in impaired migration into tissues. Common cutaneous manifestations of LAD include bacterial infections, omphalitis with delayed separation of the umbilical cord, impaired pus formation and poor wound healing. LAD is associated with significant morbidity and mortality, making early diagnosis and management integral in the care of these patients.

Methods: Molecular testing and flow cytometry for expression of CD18 were performed on 2 siblings presenting with cutaneous lesions including pyoderma gangrenosum (PG).

Results: We describe 2 siblings with a novel homozygous mutation in ITGB2 (c.2070del, p.Asp690Glufs*25) resulting in an atypical presentation of LAD-I with PG.

Conclusion: LAD should be considered in patients presenting with unexplained PG, even in the absence of significant infections or umbilical cord complications.

Statement of novelty: To the best of our knowledge, we describe a novel homozygous mutation in ITGB2 (c.2070del, p.Asp690Glufs*25) resulting in LAD-I. Patients with LAD-I may present with unexplained PG and may lack classic symptoms including umbilical cord complications.
Circulating low density lipoprotein (LDL)
Authors: Khosravi Mohsen , Hosseini-Fard Reza , Najafi Mohammad
Published: July 2018

Low-density lipoprotein (LDL) particles are known as atherogenic agents in coronary artery diseases. They modify to other electronegative forms and may be the subject for improvement of inflammatory events in vessel subendothelial spaces. The circulating LDL value is associated with the plasma PCSK-9 level. They internalize into macrophages using the lysosomal receptor-mediated pathways. LDL uptake is related to the membrane scavenger receptors, modifications of lipid and protein components of LDL particles, vesicular maturation and lipid stores of cells. Furthermore, LDL vesicular trafficking is involved with the function of some proteins such as Rab and Lamp families. These proteins also help in the transportation of free cholesterol from lysosome into the cytosol. The aggregation of lipids in the cytosol is a starting point for the formation of foam cells so that they may participate in the primary core of atherosclerosis plaques. The effects of macrophage subclasses are different in the formation and remodeling of plaques. This review is focused on the cellular and molecular events involved in cholesterol homeostasis.
“Stop doing this at once!”: The preferred use of modality for advice-giving by English language learners
Authors: Zalaltdinova Liya
Published: July 2018

This study seeks to explore (1) how English Language Learners (ELLs) of Chinese, German and Brazilian backgrounds develop their pragmatic knowledge of modality use for advice/suggestion-giving in English, and (2) if they demonstrate some common or diverse pattern(s) of its use.

For that purpose, a dataset was developed by analyzing 270 advise-giving ELLs’ essays from the EF-Cambridge Open Language Database for the use of modal devices by learners at elementary, intermediate and advanced proficiency levels; from China, Germany, and Brazil. Three main statistical analyses were performed: MANOVA, VanValen’s test, and Discriminant Function Analysis.

The results of this study indicate that the development of pragmatic knowledge of modality use is not a linear process; and that ELLs demonstrate common patterns of modality use regardless of the sociocultural background they belong to.
Politeness strategies and the representation of women in the Holy Qur’an
Authors: Al Momani Kawakib , Migdadi Fathi , Rabab’a Eman
Published: July 2018

The goal of this study is to examine the strategies of politeness used in the Qur’an, the holy book of Muslims, to address and represent women. Women have been represented negatively in many different types of texts through face-threatening acts that sustain masculine power and hegemony. This study attempts to investigate the image of women in the most sacred book of Muslims. Two aspects are examined herein: the representation of women in relation to sensitive issues like sex and marriage, and the forms of address and reference to women. A qualitative approach is used to provide interpretations of the hidden meanings in the selected excerpts, adopting Brown and Levinson’s theory of politeness and Leech’s maxims of politeness as the guides for the analysis. The analysis has revealed that women all through Qur’an have been addressed and referred to decently and politely. Unlike most of the other topics where bald-on-record strategies are used, the use of off-record strategies and positive and negative face strategies of politeness have been found to be dominant in discussion of issues relevant to women. These strategies have been used to avoid unpleasant communication in spiritual issues, and also to avoid misrepresentation of women, demeaning of their persons, causing any embarrassment, and thereby saving the face of both women and recipients. However, bald-on-record strategies are sometimes used in topics related to legal matters concerning familial and social unity and solidarity. The analysis has demonstrated the means by which language is used in the Glorious Qur’an to courteously address women. Concerning interpersonal maxims, the approbation, modesty, sympathy, tact, and agreement maxims have shown to be evident in addressing and referring to women. This study will contribute to the field of pragmatics and will lead to cross-religious and cross-cultural understanding during a period where Islam and its teachings are being widely questioned and examined.
A test for detecting differential indirect trans effects between two groups of samples
Authors: Chaturvedi Nimisha , Menezes Renée X. de , Goeman Jelle J. , Wieringen Wessel van
Published: July 2018

Integrative analysis of copy number and gene expression data can help in understanding the cis and trans effect of copy number aberrations on transcription levels of genes involved in a pathway. To analyse how these copy number mediated gene-gene interactions differ between groups of samples we propose a new method, named dNET. Our method uses ridge regression to model the network topology involving one gene’s expression level, its gene dosage and the expression levels of other genes in the network. The interaction parameters are estimated by fitting the model per gene for all samples together. However, instead of testing for differential network topology per gene, dNET tests for an overall difference in estimated parameters between two groups of samples and produces a single p-value. With the help of several simulation studies, we show that dNET can detect differential network nodes with high accuracy and low rate of false positives even in the presence of differential cis effects. We also apply dNET to publicly available TCGA cancer datasets and identify pathways where copy number mediated gene-gene interactions differ between samples with cancer stage lower than stage 3 and samples with cancer stage 3 or above.

β-Site amyloid precursor protein cleaving enzyme 1 (BACE1) is required for the production of β-amyloid (Aβ), one of the major pathogenic molecules of Alzheimer’s disease (AD), and is therefore being actively pursued as a drug target for AD. Adult hippocampal neurogenesis (AHN) is a lifelong process that is known to be important for learning and memory and may have the potential to regenerate damaged neural tissue. In this study, we examined whether BACE1 regulates AHN, which holds important implications for its suitability as a drug target in AD. Cohorts of 2-month-old wild-type (BACE1+/+), heterozygous, and homozygous BACE1 knockout mice (BACE1+/–and BACE1–/–, respectively) were injected with 5-bromo-2′-deoxyuridine (BrdU) and sacrificed 1 day later to examine the impact of loss of BACE1 on neural precursor cell (NPC) proliferation in the adult brain. Parallel cohorts of mice were sacrificed 4 weeks after BrdU injection to determine the effects of BACE1 on survival and differentiation of newborn NPCs. We found that NPC proliferation was increased in BACE1–/–mice compared to BACE1+/+mice, while no difference was observed in NPC survival across genotypes. Differentiation of NPCs to neuronal lineage was impaired in BACE1–/–mice. However, no differences were observed in astrogenesis, the proportion of immature neurons, or the production of oligodendrocytes across genotypes. Importantly, corresponding with a decrease in neuronal differentiation in the absence of a complementary increase in an alternate cell fate, BACE1–/–mice were found to have a pool of undifferentiated NPCs in the hippocampus compared to BACE1+/+and BACE1+/–mice.
Wakefulness Is Promoted during Day Time by PDFR Signalling to Dopaminergic Neurons inDrosophila melanogaster
Authors: Potdar Sheetal , Sheeba Vasu
Published: July 2018

Circadian clocks modulate timing of sleep/wake cycles in animals; however, the underlying mechanisms remain poorly understood. InDrosophila melanogaster, large ventral lateral neurons (l-LNv) are known to promote wakefulness through the action of the neuropeptide pigment dispersing factor (PDF), but the downstream targets of PDF signalling remain elusive. In a screen using downregulation or overexpression (OEX) of the gene encoding PDF receptor (pdfr), we found that a subset of dopaminergic neurons responds to PDF to promote wakefulness during the day. Moreover, we found that small LNv(s-LNv) and dopaminergic neurons form synaptic contacts, and PDFR signalling inhibited dopaminergic neurons specifically during day time. We propose that these dopaminergic neurons that respond to PDFR signalling are sleep-promoting and that during the day when PDF levels are high, they are inhibited, thereby promoting wakefulness. Thus, we identify a novel circadian clock pathway that mediates wake promotion specifically during day time.
Nausea-Induced 5-HT Release in the Interoceptive Insular Cortex and Regulation by Monoacylglycerol Lipase (MAGL) Inhibition and Cannabidiol
Authors: Limebeer Cheryl L. , Rock Erin M. , Sharkey Keith A. , Parker Linda A.
Published: July 2018

Using the rat conditioned gaping model of nausea, the interoceptive insular cortex (IIC) has been identified as a critical site for the regulation of lithium chloride (LiCl)-induced nausea. Indirect evidence supports a model where serotonin (5-HT) acts on postsynaptic 5-HT3receptors and its release is suppressed by elevating 2-arachidonylglycerol (2-AG) by monoacylglycerol lipase (MAGL) inhibition to suppress nausea. Here, we directly test the hypothesis that systemic LiCl elevates 5-HT in the IIC, and this is prevented by pretreatments that reduce 5-HT release. Using male Sprague Dawley rats, LiCl (but not saline), elevated 5-HT selectively in the IIC, for 20 min after LiCl administration (127.2 mg/kg, i.p.). Systemic pretreatment with the MAGL inhibitor, MJN110, prevented the LiCl-induced elevation of 5-HT in the IIC. Systemic cannabidiol (CBD), which reduces LiCl-induced nausea by acting at 5-HT1Asomatodendritic autoreceptors, also prevented LiCl-induced elevation of 5-HT in the IIC. Since 5-HT3receptor agonists delivered to the IIC produce nausea, we tested and confirmed the hypothesis that the intra-IIC administration of 5-HT3receptor antagonist, ondansetron, but not MJN110, would prevent LiCl-induced conditioned gaping reactions produced by intra-IIC administration of the 5-HT3receptor agonist,m-chlorophenylbiguanide (mCPBG). Finally, we demonstrate that exposure to a LiCl-paired flavor (but not a saline-paired flavor) produces elevated 5-HT release in the IIC, while rats display conditioned gaping reactions. These results confirm that LiCl-induced nausea is triggered by elevated 5-HT release in the IIC and is attenuated by treatments that reduce 5-HT availability in this region.

Complex Haplotypes of GSTM1 Gene Deletions Harbor Signatures of a Selective Sweep in East Asian Populations
Authors: Saitou M , Satta Y , Gokcumen O
Published: July 2018

The deletion of the metabolizing Glutathione S-transferase Mu 1 (GSTM1) gene has been associated with multiple cancers, metabolic and autoimmune disorders, as well as drug response. It is unusually common, with allele frequency reaching up to 75% in some human populations. Such high allele frequency of a derived allele with apparent impact on an otherwise conserved gene is a rare phenomenon. To investigate the evolutionary history of this locus, we analyzed 310 genomes using population genetics tools. Our analysis revealed a surprising lack of linkage disequilibrium between the deletion and the flanking single nucleotide variants in this locus. Tests that measure extended homozygosity and rapid change in allele frequency revealed signatures of an incomplete sweep in the locus. Using empirical approaches, we identified the Tanuki haplogroup, which carries the GSTM1 deletion and is found in approximately 70% of East Asian chromosomes. This haplogroup has rapidly increased in frequency in East Asian populations, contributing to a high population differentiation among continental human groups. We showed that extended homozygosity and population differentiation for this haplogroup is incompatible with simulated neutral expectations in East Asian populations. In parallel, we found that the Tanuki haplogroup is significantly associated with the expression levels of other GSTM genes. Collectively, our results suggest that standing variation in this locus has likely undergone an incomplete sweep in East Asia with regulatory impact on multiple GSTM genes. Our study provides the necessary framework for further studies to elucidate the evolutionary reasons that maintain disease-susceptibility variants in the GSTM1 locus.

Conscientização da metamorfose: discussão sobre os conceitos de inclusão e integração no âmbito da inclusão sociodigital
Authors: Neves Barbara Coelho , Freire Isa Maria , Suaiden Emir José
Published: July 2018

Este artigo de revisão analisa aspectos da denominação “inclusão” e suas implicações para a reflexão sobre uma “conscientização” a respeito da inclusão digital. De um lado, é observado o par dialético inclusão/exclusão social e, por outro, o conceito de integração. Esta observação é desenvolvida a partir da conscientização de aspectos contemporâneos da realidade sociodigital brasileira. Inicialmente é analisado o termo de inclusão social, sinalizando o discurso que emerge do lugar do incluído e como este se reflete no debate da inclusão digital. O termo inclusão digital é discutido a luz do conceito de integração, refletindo a partir das zonas de vulnerabiblidade social. A metodologia foi bibliográfica desenvolvida a partir de quadro teórico e empírico para construção de uma revisão, com proposta teórica, com associações e interpretações livres dos conceitos abordados. Por fim, o texto fornece uma reflexão das contribuições desses conceitos para a inclusão digital, problematizando a partir da compreensão de “metamorfose” de Franz Kafka, destacando que se trata de um movimento social e histórico.
Mediação e Resolução de Conflitos Escolares: Criminalização ou Educação?
Authors: Pimenta Carlos Alberto Máximo , Incrocci Ligia Maria De Mendonça Chaves
Published: July 2018

Este artigo faz a reflexão sobre os processos de mediação e resolução de conflitos no interior da escola, em que coloca em pauta a tensão entre criminalização e a educação do aluno envolvido em agressões ou manifestações de violência. Objetiva-se evidenciar os elementos presentes no cotidiano escolar, dentro das possibilidades de suas ações pedagógicas, os quais podem contribuir para a superação de sua postura de criminalização-policial-repressiva. A mediação, técnica no campo das inovações jurídicas aplicada à sociedade para intervenções públicas e privadas de resolução de conflitos, ultrapassa a sua dimensão funcional, dogmática e normativa no campo do direito. Na educação, se constitui em instrumento de revisão do papel formador da escola. Para esta se faz necessário interpretar os clamores da juventude e as distintas formas de expressão de violência, levando-se em consideração o imaginário, a cultura e os modos de ser, sentir, pensar, viver e experienciar a vida daqueles que compõem o cotidiano escolar.
Indústria cultural e distração concentrada: as plataformas digitais e o ensino personalizado
Authors: Castro Camila Sandim de , Soares Zuin Antônio Álvaro
Published: July 2018

A cultura digital se faz cada vez mais presente nas salas de aula por meio do uso de recursos tecnológicos, tais como as plataformas digitais de ensino e aprendizagem. De fato, professores têm utilizado tais recursos principalmente com a intenção de atenuar determinados impasses educacionais, tal como o desinteresse discente pela transmissão dos conteúdos das disciplinas escolares. Contudo, os mesmos aparelhos utilizados na educação como tentativa de sanar tais impasses estão contribuindo para acentuar a falta de concentração de professores e alunos em suas atividades escolares. Um dos motivos é a utilização irrefletida dessas plataformas, dentre as quais se destaca a Geekie. Através do chamado ensino personalizado, esta plataforma tem atingido um número crescente de professores e alunos ao oferecer diversas opções de ensino e aprendizagem virtual.  Diante desse contexto, os autores deste artigo têm como objetivo discutir os efeitos da utilização acrítica das plataformas digitais de ensino e aprendizagem para o processo formativo dos agentes educacionais, principalmente por meio da promoção do ensino personalizado.PALAVRAS-CHAVE: Tecnologia educacional; Formação cultural; Indústria Cultural.
As relações entre equipes, suporte social e bem-estar subjetivo
Authors: Oliveira Maisa Sangy Guedes , Rezende Manuel Morgado
Published: July 2018

Este estudo teve como objetivo investigar o papel moderador de potência de equipes sobre as relações entre percepção de suporte social e bem-estar subjetivo, mediante delineamento longitudinal. Participaram da pesquisa 249 adolescentes escoteiros, provenientes de 53 equipes. O estudo foi realizado nas cidades de Contagem e Belo Horizonte, Minas Gerais. Os resultados demonstraram que a percepção de suporte social e a potência de equipes influenciaram positiva e significativamente o bem-estar subjetivo dos adolescentes, porém, a potência de equipes não foi capaz de moderar a relação entre percepção de suporte social e bem-estar subjetivo. Logo, os adolescentes desfrutavam de bem-estar e saúde psíquica, condição que se manteve ao longo do tempo. Tais evidências asseguram o papel promotor de bem-estar subjetivo tanto de percepção de suporte social quanto de potência de equipes na saúde mental do indivíduo.
A conjuntura após junho de 2013: olhares cruzados sobre participação política e resistência
Authors: Euzébios Filho Antonio , Guzzo Raquel Souza Lobo
Published: July 2018

Resumo Buscamos compreender o que pensam jovens sobre a conjuntura, especialmente no Brasil, após as chamadas manifestações de junho. Em um cenário marcado pela crise social e econômica do capitalismo, quisemos entender como estudantes universitários e de um cursinho popular relacionam-se com o contexto político atual. Foram realizadas entrevistas e o conteúdo foi interpretado com base no materialismo histórico e dialético. Com isto, notamos que os participantes não enxergam um caminho concreto para superação dos problemas identificados nesta conjuntura, a saber: a existência de uma onda conservadora e corrupção, associados à retirada de direitos sociais. Em geral, partidos e movimentos sociais não estão no horizonte de participação, assim como as eleições não foram citadas como um caminho para alcançar demandas populares, corroborando a existência de uma crise de representatividade política, que é reforçada pela falta de alternativa política ao que está posto.
Pesquisa narrativa com mulheres que usam drogas: uma experiência etnográfica feminista
Authors: Queiroz Isabela Saraiva de , Prado Marco Aurélio Máximo
Published: July 2018

Resumo Trata-se de pesquisa narrativa inscrita no campo epistemológico feminista, que buscou conhecer a trajetória de vida de mulheres usuárias de crack. Foi realizada uma etnografia multissituada/multilocal, que partiu da escuta de usuárias inseridas num serviço público de saúde mental para, na sequência, seguir duas delas pelos espaços nos quais circulavam, quais sejam, abrigo, escola, equipamentos de saúde, além de suas próprias casas. Como método de coleta de dados foi utilizada a técnica de entrevista narrativa. A escuta das mulheres possibilitou a desarticulação de sentidos fixos e desafiou a inteligibilidade orientadora das práticas de cuidado às pessoas que usam drogas. Foram ressaltados os limites que a condição de usuária de um serviço de saúde mental estabelece à enunciação de um saber válido das mulheres sobre si mesmas, sendo suas narrativas produto do discurso sobre elas elaborado pelo campo da saúde, que institui e prescreve sua própria materialização como usuárias de drogas.
Algumas reflexões sobre o corpo no cenário psicanalítico atual
Authors: Fortes Isabel , Winograd Monah , Perelson Simone
Published: July 2018

Resumo Busca-se levantar indagações centrais acerca da presença do corpo na clínica psicanalítica e na cultura contemporânea. Para tal finalidade, examina-se o quanto essa problemática participa das transformações sociais testemunhadas nas últimas décadas. Em seguida, compara-se o corpo da biologia e o corpo da psicanálise, a fim de enfatizar a especificidade deste último. Esse problema remete à noção psicanalítica de corpo pulsional, aos limites da representação psíquica em psicanálise e à afirmação de que há nesse campo uma permeabilidade entre o registro da pulsão e o da representação. Além desses dois registros, o artigo propõe também incluir o corpo biológico como uma das dimensões do corpo metapsicológico em Freud.

Authors: Zin Roque Alberto , Bombana Ligia Pichetti , Barcellos Paulo Fernando Pinto
Published: July 2018

Resumo No presente trabalho o método da matriz BCG foi adaptado para ser utilizado na avaliação do desempenho das equipes de vendas de duas empresas de segmentos e tamanhos diferentes, sendo uma empresa fabricante de móveis e a outra uma fabricante de fios especiais para tricô e decoração. Depois de apurados os resultados, as equipes de vendas de ambas as empresas foram classificadas em uma matriz que relaciona o seu faturamento com a margem de contribuição e o lucro de cada uma. A classificação das equipes foi feita em relação aos resultados das empresas. A sua alocação em quadrantes ilustra o desempenho quantitativo e qualitativo de cada equipe de vendas em relação à média da empresa. Os resultados mostram a similaridade de posicionamento das equipes de venda, mesmo tratando-se de empresas em segmentos diferentes, bem como as distorções geradas com o uso de rateio de custos fixos na análise de desempenho.

Abstract The present study assessed the percentage of survival and metamorphosis of larval stages of Caligus rogercresseyi (Boxshall and Bravo, 2000) nauplius I, nauplius II to and nauplius II to copepodite, conducting bioassays in triplicate with 50 larvae each, nauplius I or nauplius II, at temperature of 12 °C, 15 °C and 18 °C; salinity 20, 23, 25, 2729, 31, 33 and 35 g/L and oxygen saturation with ranges between 30-60%, 90-100% and 190 - 200%. Bioassays were performed in station Quillaipe of Fundación Chile, Puerto Montt, Chile. It is concluded that the temperature is inversely proportional to the time of metamorphosis and survival of the larvae of Caligus rogercresseyi . In salinity is observed that increased this, greater is the percentage of survival and metamorphosis is faster, while the larvae do not survive less than 20g/L. Oxygen saturation ranges indicate that the larvae do not survive at saturations between 30-60%, and it had no differences between 90-100% saturation and 190-200%.
