Published: September 2017

Tattoos, piercing, and scarification are now commonplace among adolescents and young adults. This first clinical report from the American Academy of Pediatrics on voluntary body modification will review the methods used to perform the modifications. Complications resulting from body modification methods, although not common, are discussed to provide the pediatrician with management information. Body modification will be contrasted with nonsuicidal self-injury. When available, information also is presented on societal perceptions of body modification.

Authors: Flores March Nieves María , Chire Fajardo Gabriela Cristina , Lescano Anadón Carlos Eduardo
Published: September 2017

The effects of replacing cocoa butter with different percentages and proportions of a mango kernel fat/palm olein (MKF/POL) blend, are reported. Samples were prepared by melting together mango kernel fat, palm olein, cocoa butter and cocoa mass and powdered sugar combinated. The samples were milled, conched, tempered, and molded to obtain three sets of seven samples as follows: one control omitting mango kernel fat and palm olein, and six samples with cocoa butter replacement of 15 and 22.5% and MKF/POL ratios of 2.3, 4.0, and 9.0. Casson viscosity, Casson yield stress, fat bloom and sensory acceptability were all measured. In fact, all samples had achieved a low Casson viscosity (ηCA) and Casson yield stress (τ_oCA), which indicates molding and enrobing as appropriate uses. In addition, some significant differences (p ≤ 0.05) were found among samples. Fat bloom was accelerated in the samples relative to control, but high MKF proportions tended to retard appearance of fat bloom. No differences were observed in organoleptic properties between samples and control.

Published: September 2017

The sustainability of guadua forests under management was assessed throughout the emergy analysis approach. The system analyzed correspond to guadua forest whose major product are culms for commercial purposes. In order to calculate the sustainability, available information on purchased inputs, renewable and nonrenewable natural resources as well as external factors, which can affect the system such as labor or inputs (ie. fuel consumption), was used for calculate indexes which describe relationship among the employed natural resources. The results showed the guadua forest system under management does not depend on external inputs and its sustainability is above 90%. In fact, the recovery ability after harvesting shown by these guadua forests is associated with a proper management, which contributes to the ecosystem conservation of functions. Considering the current management conditions, the guadua forest system is sustainable although highly dependent on natural resources. Under these conditions, the system become vulnerable since the management should be focused on guaranteeing the current conditions and therefore, their conservation.
Effect of fermentation time on phenolic content and antioxidant potential in Cupuassu (Theobroma grandiflorum (Willd. ex Spreng.) K.Schum.) beans
Authors: Cuellar Alvarez Laura , Cuellar Alvarez Natalia , Galeano Garcia Paula , Suárez Salazar Juan Carlos
Published: September 2017

Cupuassu (Theobroma grandiflorum (Willd. ex Spreng.) K.Schum.) is an evergreen tree in the family Malvaceae, with nutritional qualities of interest in the food and cosmetic industry. It is necessary for its processing, in addition to other processes, to perform a fermentation, affecting its chemical composition. Therefore, the effect of fermentation time on the phenolic content and antioxidant activity of Cupuassu (T. grandiflorum) beans, was determined. During this process, the chemical properties of the beans and the phenolic content were evaluated every two days; also quantifying the secondary metabolites Catechin, Epicatechin, Theobromine and Caffeine by high performance liquid chromatography (HPLC). The antioxidant activity was analyzed using the ABTS, DPPH, and FRAP assays. Analysis of phenolic content and antioxidant activity showed a decrease after 6 days of fermentation. Therefore, it is not recommended to continue fermentation after this period due to a negative influence of the process on the bioactive substances (Catechins) content, and the reduction of the ability to inhibit free radicals, exhibited by Cupuassu beans.

Entrevista a Jorge Bertheau
Authors: Grané Jorge
Published: September 2017

Jorge Bertheau construyó su casa de ladrillo, en Escazú, hace 35 años. Estudió Arquitectura en México y, a su regreso, trabajó en el estudio de Rafael “Felo” García con quien entabló una profunda amistad. Más adelante, Edgar Brenes se unió a ellos y juntos gestaron la idea de fundar la Escuela de Arquitectura de la Universidad de Costa Rica (UCR), la que tuvo poco apoyo por parte de las autoridades universitarias. Con una beca ofrecida por Inglaterra, Jorge Bertheau y Felo García fueron a ese país a conocer programas de estudio. Más tarde se les unió Edgar Brenes. A su regreso, en 1971, se abrió la Escuela, con la consigna de “aprender a aprender”. La flamante Escuela tuvo detractores y seguidores. Entre estos últimos se destacó la figura del Ingeniero Walter Sagot. A la lucha por la supervivencia de la Escuela, Bertheau la califica como “el momento heroico” de la misma, que luego se diluyó con otra gente y otras ideas. Muchos profesores se acercaron, en sus inicios, con entusiasmo, para  apoyar la misión de la Escuela y así se formaron, con éxito los primeros arquitectos costarricenses.

Aim. To study the specific activity of the microemulsion form of the matrix insulin transdermal delivery system in vivo on the experimental streptozotocin model of type I diabetes.

Materials and methods.Male rats (n = 25) were randomized to the experimental and control groups. TDS insulin with a microemulsion composition was applicated to the animals of the experimental group (n = 15) for 4 days with daily replacement of TDS and control of the glycemia level. The glycemia level of the control group rats (n = 10) was determined throughout the experiment. The blood glucose concentration was measured using glucometer One Touch Select (USA).

 

Results.The average blood glucose level in experimental group was 28.4 ± 2.3 mmol/l before application of TDS insulin. The average glycemic index was 21.2 ± 3.1 mmol/l (p < 0.001) during of TDS application. The blood glucose decrease was 26 ± 8% relative to baseline values. The glycemia was 28.4 ± 1.4 mmol/l in the control group rats throughout the experiment.

Conclusion.A significant decrease of blood glucose level with TDS insulin application in rats with experimental type 1 diabetes demonstrates the existence of the specific activity of the microemulsion matrix transdermal delivery system of insulin.

Authors: Park Kyung Min , Park Ki Dong , Sevastianov V. I. , Nemetz E. A. , Vasilets V. N.
Published: September 2017

In situ crosslinkable hydrogels have been widely used as therapeutic implants and vehicles for a broad range of biomedical applications including tissue regenerative medicine because of their biocompatibility and easiness of encapsulation of cells or signaling molecules during hydrogel formation. Recently, these hydrogel materials have been widely utilized as an artificial extracellular matrix (aECM) because of its structural similarity with the native extracellular matrix (ECM) of the human body and its multi-tunable properties. Various synthetic, natural, and semisynthetic hydrogels have been developed as engineered cellular microenvironments by using various crosslinking strategies. In this review, we discuss how in situ forming hydrogels are being created with tunable physical, chemical, and biological properties. In particular, we focus on emerging techniques to apply advanced hydrogel materials for engineered cellular microenvironments.

Formation of tissue-engineered construct was performed in a specially developed bioreactor. At first, a cellengineered construct of human cartilage tissue consisting of biopolymer microstructured collagen-containing hydrogel, mesenchymal stromal cells of human adipose tissue (hADMSCs) and induction chondrogenic culture medium was prepared and placed in a perfusion bioreactor. As a result, on the 16th day of the study hADMSCs obtain a flattened shape typical for chondroblasts and demonstrate high proliferative activity with the formation of their own extracellular matrix. Histological analysis of the cultured system indicates the beginning of the formation of a tissue-engineered construct of human cartilage tissue.
A Case Study of the Effect of Political Conflict between Countries on the Travel Decision-making Process: Focusing on the THAAD Political Conflict between South Korea and China
Authors:   The Tourism Sciences Society Of Korea, An So-Hyun , Juan Yuxian , Lee Choong-Ki
Published: September 2017

This study examined the effect of the THAAD political conflict between South Korea and China on the travel decision-making process of tourists who had planned to travel to Korea or China, using a case study. The results of the study were that research participants appeared to feel anxiety upon recognizing the political conflict between Korea and China. The cause of the anxiety was attributable to a conflict of values resulting from the possibility of physical and psychological violence. As research participants predicted the possibility of danger and gathered information it tended to affect whether they took or canceled their trip. Their choice at this moment can be interpreted by applying the self-categorization theory. The research participants who were influenced by social identity were more likely to cancel their trip according to their social values. On the contrary, those participants influenced by personal identity took or canceled their trip according to personal values. The socio-psychological background of Koreans and Chinese should be taken into consideration throughout this self-categorization.
The Impact of Perceived Service Quality on Satisfaction and Behavioral Intentions: Applying the Three Dimensional Service Quality Model
Authors:   The Tourism Sciences Society Of Korea, Lee Yu-An , Kim In-Sin
Published: September 2017

Based on Brady & Cronin (2001) comprehensive third-order factor model of service quality (interaction, environmental, outcome quality), this study: (1) identifies exhibition service quality factors that promote participant satisfaction, (2) examines the influence of satisfaction on purchase and revisit intentions. Brady and Cronin (2001) argued that interaction quality is affected by the attitudes, behavior, and expertise of the trade show personnel. Environment quality is influenced by ambient conditions, design factors, and social factors. Outcome quality is affected by waiting time, tangibles, and valence. To test the conceptual model of this study empirically, questionnaires were distributed among 390 visitors throughout Food industrial exhibitions in BEXCO in 2015. We conducted second order factor analysis of service quality and research hypotheses were analyzed using structural modeling analysis utilizing SPSS 18.0 and AMOS 18.0. The findings indicate (1) three factors (interaction quality, holistic environment and outcome quality) impact satisfaction positively, (2) participant satisfaction positively influences revisit intention and the intention to purchase a related product after the exhibition. The study results reveal that outcome quality is the strongest factor influencing customer satisfaction. Theoretical and managerial implications are provided to strengthen Korea's service competitiveness in exhibition industries.
The Effect of a Work-Life Balance on Social Support, Affective Commitment, Job Satisfaction and Turnover Intention of Employees: Focusing on the Hospitality Industry
Authors:   The Tourism Sciences Society Of Korea, Kim Mi-Jung , You Hyung-Sook
Published: September 2017

The research results demonstrate that a work-life balance is related to factors associated with individual and organizational efficiency in terms of organizational commitment, job satisfaction and turnover intention. The results were obtained from a survey conducted using questionnaires distributed to employees working in the hospitality industry throughout Busan. A total of 325 questionnaires were used for final analysis. The results of empirical analysis identified three sub factors of work life balance among hospitality industry employees and these were: work-family, work-leisure and work-growth. Among them, work-leisure and work-growth were proven to have a positive effect on affective commitment. Moreover, affective commitment was found to have a positive effect on job satisfaction while having a negative effect on turnover intention. Additionally, multiple group analysis was conducted on the level of awareness of social support. The results were that superior support affected employee commitment. However, colleague support did not lead to a moderating effect. The study showed that young employees in the hospitality business prefer a work environment in which they can control their own lives through a work life balance. The research results indicate that businesses would increase their employee commitment and performance by improving their individual quality of life.

Authors:   The Tourism Sciences Society Of Korea, Han Ji-Yeon , Kim Hong-Bumm
Published: September 2017

This study aims to extract meaningful information through a social network analysis based on Big data in order to investigate if a tourist’s awareness of destination image favorably affects competitiveness of tourist destination. A web crawler was employed to gather online review data from 117 destinations and tourism products in Seoul, Korea using Tripadvisor. This web crawler is representative of the online travel community used throughout global tourism industry. Specifically, 23 image factors and 200 components composing two aspects of cognitive and affective images were derived using a system of text mining analysis. This study tried to identify and enhance destination competitiveness by investigating a tourist’s awareness in terms of their destination image. This was measured using indicators of network analysis that were degree centrality, closeness centrality, between centrality and eigenvector centrality. The following results were found: First) 7 image components help to create a positive image of tourist awareness in terms of destination image. Second) 14 image components feel psychologically close to tourists in terms of destination image. Third) 8 image components favorable influence and enhance the competitiveness of destination. Fourth) 11 image components have a greater impact greater than the others when tourists have a perceived destination image. Implications and suggestions are presented along with the findings of the study, which will contribute to the theoretical framework by suggesting a new perspective for measuring destination image based on Big data.

Authors: Gulshan Jahida , Chowdhury Raqul I. , Islam M. Ataharul , Akhter Halida H.
Published: September 2017

The maternal morbidity data in Bangladesh is scanty. This paper employs the prospective data on maternal morbidity in rural Bangladesh to identify the potential risk factors associated with pregnancy related complications. The data were collected by the Bangladesh Institute of Research for Promotion of Essential and Reproductive Health and Technologies (BIRPERHT) during November, 1992 to December, 1993. The GEE models with different correlation structures are used and tested for the maternal morbidity data. The logistic regression model based on exchangeable correlation structure for the repeated observations appears to be the best. The findings indicate that the risk of suffering from complications is higher for unwanted pregnancy, lower level or no schooling, lower age at marriage, 5 or more pregnancies prior to the index pregnancy.

Statistical Modelling of Annual Maxima in Hydrology
Authors: Hofrichter Johannes , Harum Till , Friedl Herwig
Published: September 2017

In this paper conditional modelling of annual maxima for predicting flood water is considered. The aim is to predict flood water of rivers, where no data about discharge but data about properties of the catchment of the rivers are available. A generalized linear mixed model is used to model the annual maxima depending on properties of the catchment and to take the correlation among measurements of one year into account. The fitted means and variances according to this model are plugged into the method of moment estimates of the parameters of the Gumbel distribution to obtain some extreme quantiles. These quantiles are commonly used to predict flood water of rivers. This approach is applied to data from Styria (Austria). The result is a satisfactory model for predicting flood water for rivers, where no data about the discharge are available.

Authors: Römisch Ute , Vandev Dimitar , Zur Katrin
Published: September 2017

Testing the possibility of determining the geographical origin (country) of wines on the base of chemico-analytical parameters was the aim of the European project ”Establishing of a wine data bank for analytical parameters for wines from Third countries (G6RD-CT-2001-00646-WINE DB)” supported by the European Commission. Therefore a data base containing 400 samples of commercial and authentic wines from Hungary, Czech Republic, Romania and South Africa was created. For each of those samples around 100 analytical parameters, among them rare earth elements and isotopic ratios were measured.Besides other multivariate statistical methods of discrimination and classification the method of regularized discriminant analysis (RDA) was used to distinguish the wines of the different countries on the base of a minimal number of the most important parameters. A MATLAB-program, developed by Vandev (2004) which allows an interactive stepwise discriminant model building on the base of an optimal choice of the “nonlinearity” parameter alpha was used. This program will be described shortly and models for commercial wines with corresponding classification and prediction error rates will be given.As a result of using RDA it was possible to reduce the number of analytical parameters to the eight to infer the geographical origin of these commercial wines.
The Modelling of a Cure Fraction in Bivariate Time-to-Event Data
Authors: Wienke Andreas , Locatelli Isabella , Yashin Anatoli I.
Published: September 2017

Three correlated frailty models are used to analyze bivariate timeto- event data by assuming gamma, log-normal and compound Poisson distributed frailty. All approaches allow to deal with right censored lifetime data and account for heterogeneity as well as for a non-susceptible (cure) fraction in the study population. In the gamma and compound Poisson model traditional ML estimation methods are used, whereas in the log-normal model MCMC methods are applied. Breast cancer incidence data of Swedish twin pairs illustrate the practical relevance of the models, which are used to estimate the size of the susceptible fraction and the correlation between the frailties of the twin partners. We discuss future directions of development of the methods and additional thoughts concerning their advantages and use.

Authors: Bejtullahu Ferhat
Published: September 2017

Extreme weather events are increasing in intensity and frequency. While the social component of resilience with all its dimensions depend on all citizens, spatial and environmental components with all their dimensions depend on more from architects than from other professionals. In this context, architects have a responsibility to evaluate, design (create) and maintain resilient build environment that can better adapt to natural conditions and that can more readily absorb and recover city from different disasters. The objective of this research is to identify the role of architects in creating the building as well as the quality of urban resilience that can be implemented in a variety of contexts at national, regional or global level. Conclusions serve as a new concept to future researchers in this field and to all regional stakeholders engaged in the process of evaluating the risk related to the natural disaster. Also, it creates professional strategies for improvement of building and urban resilience.

Published: September 2017

This study aimed to find out the changes in osmo-regulatory and anti-oxidative status during lucerne re-growth, elucidating their possible links with total nitrogen (N) and phosphorus (P) concentrations. The concentrations of osmo-regulatory substances, the activities of anti-oxidative enzymes and malondialdehyde concentration tended to increase after mowing. Total N and P concentrations decreased from 13 to 18 d after mowing. All responses were organ-specific. There were negative correlations of total N and P concentrations with osmo-regulatory and anti-oxidative status mostly in stems.

Published: September 2017

The study was conducted to evaluate long-term effect of legume intensified maize based crop rotations and contrasting tillage practices and a experiment was laid out in split plot design with three tillage practices i.e. zero tillage (ZT), permanent bed (PB) and conventional tillage (CT) as main plot treatments and four legume intensified crop rotations (MWMb - maize-wheat-mungbean, MCS - maize-chickpea-Sesbania, MMuMb - maize-mustard-mungbean and MMS - maize-maize-Sesbania) as sub-plot treatments. Adoption of CA based tillage practices (ZT/PB) significantly improved maize protein yield (MPY). ZT/PB gave 7.7-14.2% higher MPY(Maize protein yield and 7.4-13.0% higher MPYA (maize protein yield for adults) over CT. Similarly, the MPY and MPYA under legume intensified cereal based rotations were invariably higher in MCS and MWMb systems compared to MMuMb and MMS rotations.The total soil nitrogen (TSN) content increased by 15.4-17.4 and 20.32-20.91% with ZT and PB over CT in 0-15 and 15-30 cm soil depths, respectively. However, among the legume intensified rotations the maize planted under MCS and MWMb rotations registered 11.3-18.0% (0-15cm) and 8.4-11.0% (15-30cm) higher TSN over MMuMb and MMS rotation. Similarly, adoption of the CA practices (ZT/PB) resulted into significant improvement in soil organic carbon (SOC) stocks compared to CT. ZT and PB among the tillage practices and MCS crop rotations among the sub-plot treatments registered higher Leaf area index (LAI) and net assimilation rate (NAR) compared to other management practices. Interaction effect of tillage practices and crop rotations were significant for MPY, MPYA, TSN and SOC stocks and all these parameters were reported maximum with ZT-MCS. Thus, our study suggests that CA based crop management with legume diversified maize based rotations (MCS and MWMb) can be advocated as sustainable intensification strategy in north-western India and other similar agro-ecologies of South Asia.
HIGH BAS AND LOW BIS IN OVERCONFIDENCE, AND THEIR IMPACT ON MOTIVATION AND SELF-EFFICACY AFTER POSITIVE AND NEGATIVE PERFORMANCE
Authors: Krupić Dino
Published: September 2017

Self-confidence, motivation, and performance outcome are vital for goal-directed behaviour. However, people do not react to a positive and negative performance in the same way. This study examines (a) the relationship between self-confidence and approach/avoidance motivation, and (b) how approach- and avoidance-oriented individuals respond to a performance outcome. The study was conducted on 93 participants. The first part of the study examined the relationship between self-confidence and approach/avoidance motivation within Reinforcement sensitivity theory, while the second part examined changes in motivation and self-efficiency in overconfident, avoidance- and approach-oriented individuals, following the positive and negative performance. Approach and avoidance tendencies were assessed by Reinforcement Sensitivity Questionnaire (RSQ) and Sensitivity to Punishment Sensitivity to Reward Questionnaire (SPSRQ). Correlational analysis showed that the Behavioural Approach System (BAS) and Sensitivity to Reward (SR) correlated positively, while Behavioural Inhibition System (BIS) and Sensitivity to Punishment (SP) correlated negatively with confidence. In addition, moderated regression analysis showed that (a) high BIS, SP and SR individuals were strongly demotivated following the negative performance, (b) while overconfident and high BAS individuals maintained their initial motivation. On the other hand, motivation in high SR, but not in the high BAS and overconfident individuals, increased after the positive performance. None of the scales predicted the change of self-efficacy either after the positive or negative performance. High BAS and low BIS in overconfident individuals may explain why they strive more toward the final goal despite drawbacks. The theoretical and practical implications of findings are discussed in the paper.
SITUACIONI ČINIOCI AFEKTIVNOG STANJA – AFEKTIVNE PROMENE TOKOM MIROVANJA I INDUKCIJE AFEKTA

Published: September 2017

Većina kognitivnih modela pretpostavlja da se depresivno raspoloženje javlja kao odgovor na određeni stresni podsticaj iz sredine čak i niskog intenziteta, dok je pretpostavka neurobioloških modela da proces koji dovodi do depresivnog raspoloženja može biti pokrenut i u odsustvu bilo kakvih zahteva ili podsticaja iz okruženja. U ovom istraživanju su proveravane pretpostavke koje proističu iz dve relativno nezavisne teorijske perspektive – kognitivne i neurokognitivne, a koje se tiču situacionih činilaca koji, zavisno od nivoa vulnerabilnosti, dovode do afektivnih promena, i eventualno mogu otpočeti razvoj depresivnih simptoma. Uzorak je bio sačinjen od 72 ispitanika prosečne starosti 25 godina (SD = 4.18), uz upadljivo veću zastupljenost ispitanika ženskog (75.3%) pola. U prvoj grupi (N = 36), ispitanici su podvrgnuti standardnoj proceduri indukcije afekta koristeći muzički metod. U drugoj grupi primenjena je procedura bihejvioralne paradigme mirovanja (N = 36). Rezultati su pokazali da su obe procedure dovele do promena u raspoloženju, a dobijen je i značajan efekat interakcije eksperimentalnog uslova, vremena merenja, i vulnerabilnosti, kada je u pitanju negativni afekat. Obe eksperimentalne procedure dovele su, u obe grupe, do značajnog pada u nivou pozitivnog afekta. Promene u afektu nastupile su i kod vulnerabilnih i kod nevulnerabilnih ispitanika. Međutim, kod vulnerabilnih ispitanika koji su imali zadatak mirovanja došlo je i do blagog povišenja negativnog afekta, koje nije registrovano u grupi sa indukcijom afekta bez obzira na vulnerabilnost. Dobijeni rezultati daju delimičnu potvrdu kognitivnim, ali i neurobiološkim modelima.

Primeiro o onde, depois o quem. Na epígrafe acima, o espaço se sobrepõe à pessoa. Ele é prioritário para o personagem pensar a si mesmo. O onde é a pergunta primária. E ela restará sem resposta. O onde é uma das preocupações geográficas quando se pensa o espaço. Seguindo o pensamento de Doreen Massey, espaço é lugar, é lugar do outro, das trajetórias distintas de nós próprios, com as quais negociamos cotidianamente a existência dos territórios que criamos e onde agimos. A convergência de múltiplas trajetórias configura-se em lugar singular, sempre aberto, em constante devir. Cada encontro de trajetórias se faz em acontecimento. Cada acontecimento é pleno de potencialidades para proliferar. Cada proliferação pode ser traduzida como vida, vida sendo entendida como aquilo que se transforma a si mesma, sempre outra, sempre em devir, em constante perguntar-se “onde estou”? Vida inominável por nunca se saber o quê, pois configurada de conexões com o que está fora de si, no espaço... ao redor... o ao redor sendo cada dia mais amplo.
A edição dos lugares: sobre fotografias e a política espacial das imagens
Authors: Queiroz Filho Antonio Carlos
Published: September 2017

Este artigo tem por intuito discutir como as imagens contemporâneas criam pensamentos e ações sobre os lugares, coisas e pessoas, o que resolvemos chamar de política espacial das imagens. Estamos lidando com o argumento de que um dos meios para que isso aconteça, está no processo de “edição” dos lugares, a exemplo dos estudos feitos pelo historiador Simon Schama (1996), sobre como as fotografias e pinturas feitas sobre o Parque Nacional Yosemite, nos EUA, nos apresentam o lugar a partir de uma dada intencionalidade, a saber, a de não permitir que os vestígios ali deixados pelas pessoas que iam lá visitá-lo aparecessem, como os lixos jogados pelo chão e que serviam, muitas vezes, de alimento para os ursos. O caráter da edição nos coloca, portanto, em contato com os traços da cultura e do pensamento espacial existente, no momento da produção daquelas imagens. Esse será o centro da discussão deste artigo, composto pelos temas da fotografia, do lugar e da experiência, conjunto imbricado que nos permite entender e, ao mesmo tempo, produzir práticas e pensamentos mais próximos daquilo que a geógrafa inglesa, Doreen Massey (2008) chamou de “multiplicidade” - de que são feitos os lugares.
Um passeio pelas imagens: a Ribeirão Preto de Tony Miyasaka

Published: September 2017

Este artigo apresenta uma reflexão sobre a pluralidade de conceitos que as imagens envolvem (desde o mundo antigo até os dias de hoje), sua concepção como uma representação material e imaterial e, finalmente, a fotografia como uma possibilidade de imagem construída. Refletimos sobre as potencialidades das fotografias como imagens que contam histórias e representam lugares, que relatam os tempos e registram espaços transformando o passado em nosso contemporâneo. Especificamos que as fotografias revelam o próprio olhar do fotógrafo. Neste sentido, apresentamos o contexto que originou a produção fotográfica de Tony Miyasaka para compreender um pouco da história e da percepção dos lugares do município paulista de Ribeirão Preto.
Crianças de Juiz de Fora (MG) e suas representações de cidade e campo
Authors: Nunes Carla Cristiane , Pinto Vicente Paulo dos Santos
Published: September 2017

Considerando campo e cidade, rural e urbano como categorias e realidades peculiares, contudo, indissociáveis, o presente trabalho focaliza as representações dessas formas e conteúdos por crianças de Juiz de Fora (MG), entre 8 e 12 anos, com experiências consideradas tipicamente urbanas, o que foi originalmente questão de investigação da dissertação de mestrado ‘É muito difícil você ver uma carroça no centro da cidade’: Crianças de Juiz de Fora (MG) e suas representações de cidade e campo. A pesquisa foi construída em coerência com os pressupostos da investigação qualitativa e teve como objetivo conhecer as representações de campo e cidade, em especial das 12 crianças participantes, por meio de seus desenhos e falas, buscando perceber as concepções que lhes estão subjacentes. Referente à temática das categorias campo/cidade/urbano/rural, o trabalho pauta-se teoricamente em autores como Henri Lefebvre, Raymond Williams, Ana Fani Alessandri Carlos, João Rua e outros. As descobertas da pesquisa são pensadas à luz de referências como Milton Santos, Paulo Freire, Rafael Straforini e Helena Coppetti Callai, na defesa de que a Geografia tem uma função social de auxílio na leitura do lugar-mundo. As imagens, os desenhos e outras formas de representações são essenciais no processo de elaboração dessa leitura que precisa transcender o aparente.
A Comprehensive Profile of Mature MicroRNA in the Pig

Published: September 2017

The pig is an important source of meat production and provides a valuable model for certain human diseases. MicroRNA (miRNA), which is non-coding RNA and regulates gene expression at the posttranscriptional level, plays a critical role in various biological processes. Studies on identification and function of mature miRNAs in multiple pig tissues are increasing, yet the literature is limited. Therefore, we reviewed current research to determine the miRNAs expressed in specific pig tissues that are involved in carcass values (including muscle and adipocytes), reproduction (including pituitary, testis, and ovary), and development of some solid organs (e.g., brain, lung, kidney, and liver). We also discuss the possible regulating mechanisms of miRNA. Finally, as pig organs are suitable candidates for xenotransplantation, biomarkers of their miRNA in xenotransplantation were evaluated.

An in vitro medium-throughput screen using M. tuberculosis H37Rv was employed to screen an in-house library of structurally diverse compounds for antimycobacterial activity.  From this initial screen, eleven 7-substituted coumarin derivatives with confirmed monoamine oxidase-B and cholinesterase inhibitory activities, demonstrated growth inhibition of more than 50% at a 50 µM concentration.  This prompted further exploration of all the 7-substituted coumarins in our library, nineteen in total, as potential antimycobacterial agents. Four derivatives showed promising antimycobacterial activity with MIC99 values of 8.31 – 29.70 µM and 44.15 – 57.17 µM on M. tuberculosis H37Rv in independent assays using Gaste-Fe and 7H9 + OADC media, respectively.   These compounds were found to bind to albumin which may explain the variations in MIC between the two assays.  Preliminary antimycobacterial evaluation of moxifloxacin resistant M. tuberculosis show that these compounds are able to maintain their activity in fluoroquinolone resistant mycobacteria.   Analysis of structure activity relationships for antimycobacterial versus neuronal enzyme inhibitory activity indicate that structural modification on position 4 and/or 7 of the coumarin scaffold may be utilized to improve selectivity towards either inhibition of neuronal enzymes or antimycobacterial effect.  Cytotoxicity evaluations of the compounds indicate moderate cytotoxicity with slight selectivity towards mycobacteria.  Further neuroprotective assays on SH-SY5Y human neuroblastoma cells indicate significant neuroprotection for selected compounds irrespective of their neuronal enzyme inhibitory properties.  These coumarin molecules are thus interesting lead compounds that may provide insight into the design of new antimicrobacterial and/or neuroprotective agents.
Found in Translation?: The new Language of Student Engagement
Authors: Mooney Phil
Published: September 2017

There has been a perceptible shift in the language of student engagement over the past 18 months. Set against the context of a changing and ever-more challenging Higher Education landscape, the author explores this shift in language, the reasons behind it and the opportunities it may afford.
Reaching hard to reach students through student learning communities
Authors: Blessinger Patrick
Published: September 2017

Because of the many hurdles and adjustments that students face during their first year at university, it is, typically, during this crucial time period that students decide to continue with their studies, transfer to another university or quit attending university altogether. Student learning communities attempt to mitigate those factors that may lead to student dissatisfaction and non-engagement. To this end, student learning communities attempt to improve student satisfaction and engagement, and concomitantly, to improve student retention and graduation rates.
The undergraduate research project as co-creation: can we describe new forms of learning gain?
Authors: Wintrup Julie
Published: September 2017

Healthcare education requires of students, practitioners and academics an unwavering commitment to improving the lives of others, while critically and remorselessly examining the complicated and imperfect conditions in which our work takes place. Coming to terms with the implications of such a commitment is a gradual process, aided by the kinds of insights provoked by involvement in research. The undergraduate research project has the potential to begin a lifelong relationship with learning that considers how to co-create healthcare knowledge, realise and negotiate power relationships and foster participatory cultures. As a valued and ubiquitous academic activity, undergraduate research also connects students with communities of practice and promotes interesting, more contemporary forms of learning gain. Yet, as highly-regulated health programmes often have little in terms of flexibility, emphasising employability and efficiency over regeneration, the case for change has to be persuasive. I suggest that describing undergraduate research in terms of learning gain, in particular the co-creation that is part of collaborative work, underlines its importance to the future of healthcare and offers an opportunity for renewal in one aspect of professional health education.
Which Lenses Best Help us Make our Practices Inclusive?

Published: September 2017

In this opinion piece, we draw on staff interviews reported on elsewhere in this issue (Marie et al, 2017) to argue that it is important to consider both characteristics of students and the provision that can make them ‘hard to reach’. We believe that the concept of ‘hard to reach’ groups is useful for identifying potential barriers. Whilst it is useful to consider whom provision is designed for and whether that is appropriate, we also need to recognise that the students it is designed for may still face significant barriers to engaging with it.
Pressure Transient Analysis and Inflow Performance for Horizontal Wells

Published: September 2017

In recent years, pressure transient behavior and inflow performance of horizontal wells have received considerable attention due to the increase in horizontal drilling. In this paper we develop an interpretation methodology for horizontal well pressure transient testing. This methodology is then applied to the interpretation of an actual horizontal well test performed in Prudhoe Bay. The complex geometry associated with horizontal wells makes interpretation of well tests a difficult task. Uniquely determining the system parameters from short time (typical times for vertical well testing) pressure tests is not possible. Combining drawdown and buildup tests, with downhole flowrate measurement is critical for proper interpretation.

We also provide a solution for the Inflow Performance of a horizontal well completed in a rectangular drainage volume, where the well can be of arbitrary length and completed at any location within the drainage volume.
Production Analysis of Marcellus Shale Well Populations Using Public Data: What Can We Learn from The Past?
Authors: Myers Roger R. , Knobloch Timothy S. , Jacot R. Henry , Ayers Kimberly L.
Published: September 2017

The scope of this paper is to use publicly sourced data as a starting point for production analysis of two distinct well populations. The well populations that will be examined are horizontal Marcellus Shale wells (1) frac'd earlier in time with a defined plug-to-plug stage spacing and (2) frac'd at the same time or later in time with 1.5 to 3 times the number of stages, a production acceleration technique known as Reduced Cluster Spacing (RCS).

Public production databases were used to create snap shots of completion activity over time. To speed work flow, a more robust and regularly updated commercially available database that contains both completion and production data was used. Two distinct populations of wells for analysis were identified. A conservative decline curve analysis (DCA) was made to forecast estimated ultimate recovery (EUR) for all wells using only public data. For selected wells, reciprocal production rate versus square root of time plots were generated.

This paper will attempt to answer the following questions: (1) were statistically meaningful populations of both stimulation techniques found to exist; (2) how much production uplift did RCS achieve both early on and later time; (3) was there a real increase in EUR; (4) was there a difference in stimulation efficiency; and, (5) what can we learn by plotting P10, P50, and P90 values and EUR distribution curves for specific well populations.

To the authors' knowledge this would be the first SPE paper to explore this topic over such large Marcellus Shale well populations in Pennsylvania.
