Published: September 2017

Background Accurate risk evaluation of choledocholithiasis prior to laparoscopic cholecystectomy is essential to determine optimal management strategy. Objective Our study aimed to evaluate the accuracy of separate predictors and Vilnius University Hospital Index (VUHI = A/30 + 0.4 × B; A = total bilirubin concentration (µmol/l), B = common bile duct (CBD) diameter (mm) measured by ultrasound) diagnosing choledocholithiasis and to assess different management strategies (cholecystectomy with intraoperative cholangiography and endoscopic retrograde cholangiopancreatography (ERCP)). Methods The retrospective study included 350 patients admitted to a tertiary care centre for laparoscopic cholecystectomy for cholecystolithiasis who were investigated for concomitant choledocholithiasis. Results Choledocholithiasis was diagnosed in 182 (76.2%) cases in the high-risk group (VUHI value ≥4.7) and 44 (39.6%) in the low, odds ratio is 4.86 (95% CI: 3.00–7.88). Its sensitivity was 80.5%, specificity 54.0%, accuracy 71.1%. Dilated CBD had the highest sensitivity (92.5%) of predictors. ERCP showed better diagnostic performance than intraoperative cholangiography. Complications of ERCP were more frequent for patients without stones. There was no significant difference of outcomes between the two management strategies. Conclusion The prognostic index has good diagnostic accuracy but dividing patients into two risk groups is insufficient. The suggested model allows determining an intermediate-risk group, which requires additional investigation. Both management approaches are appropriate.
Home food availability, parents’/caregivers’ support, and family meals influence on dietary servings of low-income urban adolescent girls from Brazil
Authors: Barco Leme Ana Carolina , Tucunduva Philippi Sonia 
Published: September 2017

Abstract
Background
There is a striking lack of evidence about parents’/caregivers’ influence on their children’s dietary intake across Brazil and other middle- and low-income countries. Therefore, the purpose of this study was to identify the associations between adolescents’ dietary intake and home environment, family meals and parental support.

Methods
Cross-sectional study with 14–18 years old adolescent girls was conducted in 10 public schools in the city of São Paulo. Girls’ dietary intake, home food environment, parental support, and family meals’ frequency were self-reported by 253 adolescents. Brazilian Food Pyramid recommendation was used as reference for the dietary intake. Linear regressions were used to verify the associations between home environmental, parental support, and family meal frequency with dietary intake.

Results
Girls parents’ support for healthy eating was positively associated with the fruits group (mean (95%CI) 0.75 (0.66 to 0.84) ß = 0.26, p = 0.003), and the vegetables group (3.40 (3.08 to 3.72, ß = 0.25, p = 0.006) and negatively associated with the meat and eggs group (2.09 (1.93 to 2.25), ß = −0.14, p = 0.041). Home environment was associated with fruits group (0.73 (0.63 to 0.82), ß = 0.35, p = 0.001). The associations between sharing family meals and food groups were not statistically significant. However, girls demonstrated a positive association with dietary intake and sharing family meals.

Conclusion
Parental support and home food environment were associated with dietary intake of the adolescent girls. Future studies—mainly from low- and middle-income countries —are needed to provide additional evidence on these associations and the effects of youth home environment.
Methodological challenges and lessons learned – deconstructing studies of social reality
Authors: Gustafsson Jessica , Nielsen Poul Erik 
Published: September 2017

Abstract
Taking as point of departure three recently conducted empirical studies, the aim of this article is to theoretically and empirically discuss methodological challenges studying the interrelations between media and social reality and to critically reflect on the methodologies used in the studies. By deconstructing the studies, the article draws attention to the fact that different methods are able to grasp different elements of social reality. Moreover, by analysing the power relations at play, the article demonstrated that the interplay between interviewer and interviewee, and how both parties fit into present power structures, greatly influence the narratives that are co-produced during interviews. The article thus concludes that in order to fully understand complex phenomena it is not just enough to use a mixture of methods, the makeup of the research team is also imperative, as a diverse team are better equipped to gather a diversity of stories.
Ideals, buzzwords and true trying: ICT and communication policies in Kenya
Authors: Kivikuru Ullamaija 
Published: September 2017

Abstract
In the heyday years of modernization, a number of media policy papers were produced in new African states. Media were assessed as central for national development. Now, we are globally experiencing a New Wave of communication fever. New technology is claimed to strengthen democracy more than conventional media. It is possible to give ‘voice to the voiceless’ and increase direct democracy, but the digital divide is not easily overcome. Again, a New Wave of policy planning has emerged both nationally and internationally. This article elaborates on the policy discussions in Kenya, the acknowledged Information and Communication Technology (ICT) hub of Africa. The media history has been unpredictable and contradictory in Kenya. Thus, the expectations for changes caused by ICT are interesting; the buzzword has sold well. The major policy documents are analysed, and on their basis, expert interviews have been carried out. The goals for ICT promotion are changing in Kenya. In the beginning, ICT was assessed as a technological challenge. Today, its service side has been emphasized and connections with conventional media are carefully sought, but encouragement for citizen activism is still lacking.
The mobile phone and society in South Sudan: A critical historical-anthropological approach
Authors: Brinkman Inge , Both Jonna , de Bruijn Mirjam 
Published: September 2017

Abstract
This article outlines the development of mobile telephony in the nascent Republic of South Sudan (ROSS). We focus specifically on Juba, during turbulent times from the end of the second Sudanese Civil War in 2005 to just after independence in 2011. We highlight the complicated political relations behind the establishment of mobile networks and the main functions and importance of the mobile phone throughout this period. Despite major technical obstacles, reconnecting with (war-) dispersed relatives, providing security in the post-CPA period marked by high insecurity and symbolizing hope and access to markets were important features of mobile phone use in Juba. Mobile phones were also essential to the rapid development of migrant dominated trade and business. Through this case-study we aim to shed light on the way in which (new) communication technologies become entangled with mobility, politics and entrepreneurship in a (post)war setting characterized by a displacement economy.
Gendered identities in the consumption of mobile phones among youth in Botswana
Authors: Lesitaokana William O. 
Published: September 2017

Abstract
Research on the interactive relationship between youth and mobile phones has demonstrated that mobile devices have become indispensable in many aspects of youth lifestyles. Despite this, there is currently very limited research on mobile phone cultures in Sub-Saharan Africa. This article considers two very distinct gendered identities resulting from mobile phone consumption among students in Botswana: one involving adolescent females using colourful mobile phones and brightly coloured casings for their handsets as symbols of fashion and modernity, and the other relating to their male counterparts mostly preferring to own smartphones that are costly as these handsets gratify their sense of having a contemporary personal status. I then go on to demonstrate that although the findings from this study are analogous to those from similar studies worldwide, to a large extent, the gendered identities exhibited among youth in Botswana contexts are predicated on conventional practices entrenched in the traditional Tswana lifestyle.
Entrepreneurial Orientation and Firm Performance: Is Product Quality a Missing Link?
Authors: Yang Yang , Ju Xiao Feng 
Published: September 2017

AbstractPrior literatures have argued that the relationship between entrepreneurial orientation and firm performance may be not as straightforward as expected. With EO–performance contingency framework, this study investigates how product quality mediates the relationship between EO and firm performance. Using survey data from 153 new ventures, we find that EO dimensions have non-uniform and non-linear, rather than merely linear, relationships with product quality. Specifically, the results reveal that innovativeness and autonomy may lead to superior product quality, however, risk-taking would decrease, not increase, product quality. Proactiveness has U-shaped, not inverse U-shaped, effect on product quality and competitive aggressiveness has U-shaped, not positive linear, effect on product quality. Our results enrich the EO-performance contingency framework and highlight the significance of concerning independent and unique effects of individual EO dimension.

Published: September 2017

Abstract
Bowel endometriosis is the most common extragenital manifestation of endometriosis. Clinical suspicion is of utmost importance for achieving its diagnosis. Management of this condition is, however, always challenging to the gynaecologist. We report a case of bowel endometriosis in which the patient presented with dyschezia and haematochezia prior to her menses for the past 2 years. A 44-year-old para two woman presented with worsening dysmenorrhea and dyspareunia. She also experienced dyschezia and haematochezia prior to her menses for the past 2 years. An examination revealed a fixed retroverted uterus. A computed tomography scan showed focal bowel thickening. She underwent a colonoscopy examination and biopsy that revealed stromal endometriosis. She was subsequently treated with dienogest and became asymptomatic. Diagnosis and management of this debilitating illness was revisited and discussed.
Degradation and Mineralization of a Cationic Dye by a Sequential Photo-Sono Catalytic Process
Authors: Camacho-Alvarado Carlos , Castillo-Araiza Carlos O. , Ruiz-Martinez Richard S. 
Published: September 2017

Abstract
The photocatalysis, sonocatalysis and their combination operated sequentially have been studied to treat the decolorization and mineralization of a cationic dye, Rhodamine B, using heterogeneous TiO2 catalyst. Effects of various operating parameters such as catalyst loading, H2O2 addition, and pH on photocatalytic and sonocatalytic processes were investigated. For both photocatalysis and sonocatalysis optimum catalyst and hydrogen peroxide concentrations were observed, while the dye degradation rates were favored at acidic conditions. Photocatalysis resulted in higher color degradation efficiencies compared with sonocatalysis. Coupled photosonocatalytic process showed better efficiencies for color degradation than the achieved by individual photocatalysis and sonocatalysis operating separately, implying possible synergy; however, no synergetic effect was observed for dye mineralization. Apparently the sequential photosonocatalytic operation process was more effective in inducing color degradation than mineralization.
Augmented reality using holographic display
Authors: Lin Hung-Chun , Wu Yung-Hsun 
Published: September 2017

AbstractAugmented reality (AR) provided extra information to the user by applying virtual image onto the real environment. There are many methods achieving AR. Holographic display is one of the potential ways due to its perfect 3D demonstration. Holographic display can provide the virtual 3D object with depth information. It can be realized an AR device with real 3D scene by combing holographic display. However, it is difficult to realize a compact holographic display with wide viewing angle and enough resolution. It limits holographic display to apply to AR. In this paper, we will discuss the requirements of holographic display based on the development of LCD, including resolution (ppi), viewing angle, image quality and backlight. We wish this article can provide preliminary direction for the LCD industry to develop AR technology using holographic display.

Published: September 2017

Currently, Japan has become a country which has a big influence especially in South East Asia. They actively build bilateral and multilateral cooperation with other countries like establishing the Japan International Cooperation Agency (JICA) in August 1974. The cooperation has involved many sectors such as technology, politics, economy, social affairs and culture.On the ASEAN stage, Japan is actively promoting its culture to ASEAN countries, including Indonesia. One major program is “Pesantren Leaders’ Visit to Japan”. The program is a cooperation between the Japanese Embassy and the Center for the Study of Islam and Society (PPIM), UIN Syarif Hidayatullah Jakarta, which has run from 2004 until now.In the program, the Japanese Government every year invites several religious education leaders in Indonesia to observe the social and culture dynamics of the Japanese. Not only that, they are also invited to visit some schools, government offices, small and medium enterprises in Japan to see the latest productivity developments, including the problems and challanges they have in many sectors. As a result of its ongoing work, this bilateral program has produced a cross-cultural network and inter-faith dialogue among Islamic schools in Indonesia and Japan.DOI: 10.15408/sdi.v24i1.5152
Islam, Demokrasi, dan Institusi Politik di Indonesia, Turki, dan Dunia Islam

Published: September 2017

Edward Schneier. 2016. Muslim Democracy: Politics, Religion and Society in Indonesia, Turkey and the Islamic World. New York: Routledge.This book is one of the most recent and pivotal works in studying of democratization in Muslim world. The controversial inference from the Edward Schneier’s work is that the variable of religion, especially Islam in this context, is not appropriate enough to explain the success or failure of democracy in Muslim majority countries. By using the mix method of statistics comparison and comparative case studies in Indonesia and Turkey, he argues that the difference of colonialization, history, geopolitics and the growth of developmental economy is crucial variable to elucidate the different outcome of democratization in Muslim countries. However, this book is like a generalization from prior works regarding this topic especially in explaining Islam and democracy in both countries. Some arguments fell down repeatedly with prior scholars such as the explanation of civil Islam to explain Indonesia democratization and the role of military-Islamist relations in depicting democratization in Turkey.DOI: 10.15408/sdi.v24i1.5223

Vencidos os desafios para que a Sociologia se tornasse obrigatória nos três anos do ensino médio, o ensino dessa disciplina suscita várias reflexões. O presente estudo trata-se de uma revisão de literatura, a partir das leituras realizadas no contexto do Curso de Mestrado em Ensino, do Programa de Pós-Graduação em Ensino da Universidade do Estado do Rio Grande do Norte – Campus Pau dos Ferros – PPGE/UERN. O objetivo do artigo é abordar os principais pontos da formação e da prática docente do professor de Sociologia. Tendo em vista toda a trajetória da disciplina para se firmar como obrigatória nos três anos do ensino médio. Esse trabalho está organizado em três partes, sendo embasado bibliograficamente em MORAES (2007), MEIRELLES (2002), SILVA; SANTOS; SILVA (2009), TARDIF (2010), IANNI (2011) dentre outros. Inicialmente, abordam-se os principais pontos de contradição entre a formação e a prática docente do professor de Sociologia, pois a discrepância na formação desses profissionais já podia ser observada desde a década de 30 a partir da criação das primeiras universidades e cursos de ciências sociais no Brasil. Em seguida, Além das questões que norteiam a formação dos professores de Sociologia que lecionarão no ensino médio apresentam-se, também, alguns desafios a serem vencidos por esses profissionais no espaço da sala de aula. Desta feita, com o ensino da referida disciplina busca-se a formação do indivíduo questionador que não se acomoda diante dos fatos, criticando o senso comum.

Authors: Moya-Mata Irene , Ruiz-Sanchís Laura , Martin Ruiz Julio , Ros Ros Concepción 
Published: September 2017

El objeto de esta investigación es analizar las actividades deportivas realizadas en el medio natural representadas en los libros de texto de Educación Física (EF) en la etapa de Educación Primaria (EP), publicados en la Ley Orgánica 2/2006, de 3 de mayo, de Educación (LOE). Se analizan 4339 imágenes, recogidas en 44 libros de texto, pertenecientes a ocho editoriales españolas. Para el análisis de contenido de las imágenes se utilizó la herramienta SAIMEF (Sistema de Análisis de las Imágenes de Educación Física), elaborada ad hoc. La prueba piloto, el panel de expertos y la triangulación con varios observadores fueron algunos de los criterios de cientificidad que avalaron dicha herramienta. Los resultados muestran que la presencia de imágenes referidas a las actividades deportivas en el medio natural continúa siendo muy escasa en los libros de texto de EF. La editorial Teide representa en mayor proporción este tipo de actividades con respecto al resto de editoriales. En el tercer ciclo aparecen un mayor número de imágenes, predominando el dibujo frente a la fotografía. La actividad deportiva más representada es la orientación, con un 25.6%, incluida dentro de los deportes multidisciplinares, prevaleciendo el medio terrestre. La representación de los deportes en el medio natural varía según las editoriales analizadas. Se hace necesario incluir una mayor representación de las actividades deportivas en la naturaleza, diversificando el mayor número de prácticas, en todos los medios de realización y reorientando el deporte en el medio natural, a la vez de un cambio de conciencia social.
La construcción de instancias de juego con rasgos lúdicos en la educación física del nivel inicial
Authors: Gómez Smyth Leonardo 
Published: September 2017

El presente artículo posee como objetivo general comprender los procesos de construcción de las situaciones lúdicas en clases de Educación Física Infantil. Se ha llevado adelante un diseño metodológico sustentado en los supuestos epistemológicos de la metodología cualitativa, siendo una investigación de tipo aplicada, produciendo la información empírica en base a un trabajo de campo desarrollado en el contexto natural. El método ha sido un estudio de caso instrumental, en base a un diseño exploratorio – interpretativo, en el cual se ha desarrollado un proceso sistemático y longitudinal de observación de las clases de educación física, utilizando registros de notas de campo, video filmaciones y grabaciones de voz de los diálogos ocurridos entre el docente y los niños para recabar la información correspondiente, los cuales se unificaron en registros observacionales. La muestra ha sido de carácter no probabilística, deliberada e intencionada conformada por niños y niñas de entre cuatro y cinco años y de un docente especialista en Educación Física Infantil. La construcción de las situaciones lúdicas requiere de acciones conjuntas entre la participación guiada del docente y de niños percibidos y sentidos como jugadores atravesando fases de montaje y sostenimiento de lo lúdico en donde se exponen preferentemente ideas o reglas de carácter implícito y/o explícito como proposiciones para jugar. Por tanto, en las situaciones lúdicas, los jugadores montan y estructuran la forma de juego preparando todo lo necesario para jugar y sobre todo van configurando un sentido no competitivo en sus modos de jugar.

This research was aimed to observe the anatomical character of mangrove plants leave and examine the differences from leaves anatomical character of mangroves in Donan river and Tritih forest in Cilacap regency as an self-adaptation indicator. The method which is used was survey method by collecting leaves sample of each mangrove plants. The sample was preparated using embedding method, and stained with safranin 1% disolved in alcohol 70%. The parameter of variable which is observed in leaves anatomical character are thickness of leaves, leaves mesophyll thickness, cuticle thickness, stomata length size, and amount of stomata and trichome per leaves unit area. The data were analyzed with t-test for examining anatomical character difference. The results showed that four usual types of mangrove plants such as Achantus ilicifolius, Rhizospora mucronata, Aegiceros corniculatum, and Bruguiera gymnorrhiza have similar leaves anatomical structure. The anatomical character from polluted habitat were different from unpolluted habitat. This differences was showed in leaves mesophyll thickness, cuticle thickness, stomata length size, and amount of stomata and trichome per mm2 leaves unit area.
