Published: September 2017

Decisions and investments made today determine the assets and capabilities of the U.S. Navy for decades to come. The nation has many options about how best to equip, organize, supply, maintain, train, and employ our naval forces. These decisions involve large sums of money and impact our national security. Navy leadership uses simulation-based campaign analysis to measure risk for these investment options. Campaign simulations, such as the Synthetic Theater Operations Research Model (STORM), are complex models that generate enormous amounts of data. Finding causal threads and consistent trends within campaign analysis is inherently a big data problem. We outline the business and technical approach used to quantify the various investment risks for senior decision makers. Specifically, we present the managerial approach and controls used to generate studies that withstand scrutiny and maintain a strict study timeline. We then describe STORMMiner, a suite of automated postprocessing tools developed to support campaign analysis, and provide illustrative results from a notional STORM training scenario. This new approach has yielded tangible benefits. It substantially reduces the time and cost of campaign analysis studies, reveals insights that were previously difficult for analysts to detect, and improves the testing and vetting of the study. Consequently, the resulting risk assessment and recommendations are more useful to leadership. The managerial approach has also improved cooperation and coordination between the Navy and its analytic partners.

Methodological challenges and lessons learned – deconstructing studies of social reality
Authors: Gustafsson Jessica , Nielsen Poul Erik
Published: September 2017

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

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

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

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.

Published: September 2017

Gongronema latifolium (Benth) called Utasi by Igbos and Arokeke by Yorubas belongs to Ascepiadaceae family. It is an herbaceous climbing plant found in the tropical region. The leaves are used for food, culinary, medicinal and other domestic purposes. The plant is found among the wild and is not cultivated in regular farms. It is one of the endanger species that stands the risk of been extinct. Therefore, the study was carried out to determine the responses of Gongronema latifolium to seven rates of NPK 15:15:15 fertilizer during 2014 and 2015 cropping seasons at the Teaching and Research Farm, Agronomy Department, Cross River University of Technology Obubra, Cross River State, Nigeria. The experimental design was a randomized complete block design. Treatments were seven rates; 0kg/ha, 50, 100, 150, 200, 250 and 300kg/ha of NPK (15:15:15) fertilizer replicated four times. Results showed that application of 300kg/ha of NPK 15:15:15 fertilizer gave a higher number of leaves, branches per plant and tallest plants than the other rates of NPK fertilizer. The highest leaf yields in hectares were obtained in plots treated with 200kg/ha in 2014 and 2015 seasons respectively.Based on these findings, farmers are advice to domesticate and cultivate Gongronema latifolium with the application of 200kg/ha NPK 15:15:15 fertilizer for optimum growth and leaf yield.

Authors: Costa Leonardo , Amato Neto João
Published: September 2017

We hereby present a proposal for a water stewardship strategy model, having the water footprint as a reference, developed from the results of a qualitative and exploratory research and by interviews with experts in the subject. The aim is to identify these experts’ contributions to a water stewardship model as from the applicability of the water footprint concept. From the contribution provided by the experts’ panel, as well as the authors’ understanding of the content of the bibliographic research conducted, a water stewardship strategy model was proposed for producing goods and services as from the water footprint concept, structured as a Plan-Do-Check-Action stewardship model. This model sought to be supported on a holistic view of the sustainable management process of water resources, besides seeking to provide an innovative and comprehensive way to account for water use and consumption along with effluent disposal. Thus, it sought to contribute to a suitable risk management and might contribute as a necessary support for the development of operational and commercial strategies, contributing significantly to the sustainable development of an organization.

Entrepreneurial Orientation and Firm Performance: Is Product Quality a Missing Link?
Authors: Yang Yang , Ju Xiao Feng
Published: September 2017

Prior 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

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

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

Augmented 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.
EDC IMPACT: Chemical UV filters can affect human sperm function in a progesterone-like manner
Authors: Rehfeld A , Egeberg D L , Almstrup K , Petersen J H , Dissing S , Skakkebæk N E
Published: September 2017

Human sperm cell function must be precisely regulated to achieve natural fertilization. Progesterone released by the cumulus cells surrounding the egg induces a Ca2+influx into human sperm cells via the CatSper Ca2+-channel and thereby controls sperm function. Multiple chemical UV filters have been shown to induce a Ca2+influx through CatSper, thus mimicking the effect of progesterone on Ca2+signaling. We hypothesized that these UV filters could also mimic the effect of progesterone on sperm function. We examined 29 UV filters allowed in sunscreens in the US and/or EU for their ability to affect acrosome reaction, penetration, hyperactivation and viability in human sperm cells. We found that, similar to progesterone, the UV filters 4-MBC, 3-BC, Meradimate, Octisalate, BCSA, HMS and OD-PABA induced acrosome reaction and 3-BC increased sperm penetration into a viscous medium. The capacity of the UV filters to induce acrosome reaction and increase sperm penetration was positively associated with the ability of the UV filters to induce a Ca2+influx. None of the UV filters induced significant changes in the proportion of hyperactivated cells. In conclusion, chemical UV filters that mimic the effect of progesterone on Ca2+signaling in human sperm cells can similarly mimic the effect of progesterone on acrosome reaction and sperm penetration. Human exposure to these chemical UV filters may impair fertility by interfering with sperm function, e.g. through induction of premature acrosome reaction. Further studies are needed to confirm the resultsin vivo.
Cross Cultural Educational Exchanges between Indonesia and Japan

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

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
O ENSINO DE HISTÓRIA E O LUGAR DO LIVRO DIDÁTICO NA TRANSPOSIÇÃO DIDÁTICA DO SABER ESCOLAR
Authors: Fernandes Aleksandra Nogueira de Oliveira , Aguiar Ana Lúcia Oliveira , Fernandes Stenio de Brito
Published: September 2017

Este artigo teve como foco de abordagem o lugar do Livro Didático (LD) de História na transposição didática do saber escolar. Destarte, a proposta aqui é de ampliar essa discussão, analisando a utilização do LD como instrumento de transposição didática do conhecimento sistematizado. A pesquisa foi realizada em uma escola pública estadual de Mossoró (RN), nas turmas do 2º ao 5° ano do Ensino Fundamental, por isso pode inserir-se no campo das pesquisas qualitativas, como um estudo de caso. Para a produção de dados foi utilizada a observação in loco, um questionário com perguntas abertas e fechadas e a análise documental. Os pressupostos teóricos que embasaram a análise foram os estudos de Bittencourt (2004) e Chevallard (1991). O desenvolvimento da investigação permitiu compreender que o LD é, de fato, utilizado no processo de transposição didática. Entretanto, verificou-se que a professora da turma em observação possui grandes dificuldades com relação à compreensão dos saberes específicos da História. Igualmente foi constatado que na transposição didática ocorre uma simplificação do conhecimento, o que, por vezes, ocasiona a superficialidade e até mesmo a distorção dos conceitos abordados.

Published: September 2017

O presente artigo tem como objetivo apresentar uma investigação comparativa dos critérios determinantes na decisão de adoção de novas tecnologias na área de gestão ambiental de duas organizações do setor de geração de energia. A opção por este setor se mostra pertinente uma vez que ele é composto de organizações balizadas por órgãos regulamentadores, submetendo-as a pressões similares. A escolha dos casos pesquisados foi intencional, tendo como critérios não apenas o acesso, como também a relevância desses no que se refere à geração de energia para o país. A metodologia empregada foi de natureza qualitativa, representando um estudo comparativo de casos. Observou--se que os critérios de natureza financeira e operacional foram predominantes. Por fim, constatou--se que influências culturais voltadas à sustentabilidade e à legislação ambiental, o contexto técnico voltado à eficiência e o contexto socioambiental em que as usinas estão inseridas interferem nos critérios para seleção e aquisição de inovações. A partir dessas observações, propõe-se um modelo conceitual.

ABSTRACT This study aimed to evaluate if ionic strength variation causes differential accumulation of heavy metals in plants of Annona emarginata (Schltdl.) H. Rainer var. ‘terra-fria’, modifying gas exchange and dry matter production. The seedlings were cultivated under different ionic strengths of the ‘Hoagland and Arnon’s’ nutrient solution (75% I, 50% I and 25% I). At 180 days after the application of the treatments, the effects of the essential heavy metals on the physiological parameters and foliar ionic concentration were assessed. The leaf gas exchanges and vegetative growth were affected by the variation in the essential heavy metals, with positive effects on the plants that were treated with 75%I. The seedlings that were grown under 75% I presented higher concentrations of Zn (24.2mg kg-1). On the other hand Fe (453mg kg-1) e Mn (803.5mg kg-1) accumulated more under 25% I, but gas exchanges and vegetative growth were reduced, compared to 50%I and 75%I. We can conclude that the ionic strength variation alters gas exchange and the dry matter accumulation, causing differential accumulation of Fe, Mn and Zn in A. emarginata, occurring inverse relationship between increased ionic strength and Fe and Mn content, besides directly relationship to the Zn content.

ABSTRACT Mexican plum (Spondias purpurea L.) ‘Cuernavaqueña’ was harvested at four ripening stages, with the aim of evaluating the concentration of bioactive compounds and antioxidant capacity in the pulp and the epicarp. The highest ethylene production (9.43 mL kg h-1) and total soluble solids concentration (23.9 °Brix) was observed in the fully ripe stage. Titratable acidity was higher in green stage compared to other analyzed ripening stages in both pulp (0.48 %) and epicarp (0.32 %). Fully ripe plum epicarp presented the highest content of total phenols (GAE 190 mg g-1), flavonoids (QE 214 mg g-1), and carotenoids (853 mg g-1) compared to other ripening stages. The antioxidant capacity was higher in the epicarp of the fully ripe fruit compared to the other ripening stages: DPPH (1087 µM TE /100 g), ABTS (1534 µM TE/100 g), and FRAP (1764 µM TE/100 g). Significant correlations (r = 0.60 *** to 0.95 **) between bioactive compounds concentrations and antioxidant activity were obtained.

Published: September 2017

ABSTRACT The effect of organic fertilization with cattle manure on fertility properties of soils with different clay contents was evaluated; as well as the influence of cattle manure fertilization on the production of lettuce, and on subsequent arugula and common chicory grown in these soils. The experiment with pot plants was arranged in randomized blocks and analyzed in a 3x6 factorial design with four replications. The treatments consisted of three soil types with different clay contents (166; 362; 565 g kg-1) and six cattle manure rates (0; 10; 20; 40; 80, and 160 t ha-1). Batches of each soil were manured, limed, filled in pots, moistened, and incubated for 30 days. Then, mineral base fertilization was applied and one lettuce seedling per each pot was grown. After lettuce harvest, the residual effect of organic fertilization was assessed in two subsequent crops, first arugula and then common chicory. The application of up to 160 t ha-1 cattle manure reduces soil acidity and increases nutrient contents, particularly of P, K and Zn, in soils with 165 to 565 g kg-1 clay content. Fertilization with cattle manure at rates of up to 160 t ha-1 increases electrical conductivity of soils, without affecting growth and yield of the leafy vegetables. Cattle manuring increases the yield of lettuce, as well as of arugula and common chicory grown afterwards.

ABSTRACT In flood plains, cover crops are able to alter soil properties and significantly affect rice nutrition and yield. The aims of this study were to determine soil properties, plant nutrition, and yield of tropical rice cultivated on flood plains after cover crop cultivation with conventional tillage (CT) and no-tillage system (NTS) at low and high nitrogen (N) fertilization levels. The experimental design was a randomized block in a split-split-plot scheme with four replications. In the main plots were cover crops [sunhemp (Crotalaria juncea and C. spectabilis), velvet bean (Mucuna aterrima), jackbean (Canavalia ensiformis), pigeon pea (Cajanus cajan), Japanese radish (Raphanus sativus), cowpea (Vigna unguiculata)] and a fallow field. In the subplots were the tillage systems (CT or NTS). The nitrogen fertilization levels in the sub-subplots were (10 kg N ha-1 and 45 kg N ha-1). All cover crops except Japanese radish significantly increased mineral soil nitrogen and nitrate concentrations. Sunhemp, velvet bean, and cowpea significantly increased soil ammonium content. The NTS provides higher mineral nitrogen and ammonium content than that by CT. Overall, cover crops provided higher levels of nutrients to rice plants in NTS than in CT. Cover crops provide greater yield than fallow treatments. Rice yield was higher in NTS than in CT, and greater at a higher rather than lower nitrogen fertilization level.

ABSTRACT The soybean-corn succession in no-tillage system (DSS) is the most common cultivation practice in the state of Mato Grosso. Soils submitted to this type of system are prone to the formation of fertility gradients and surface compaction, restricting crop productivity. The objective of this work was to evaluate the physical-chemical attributes of an Oxisol after 11 years of continuous succession of soybean and corn in direct seeding, using geostatistical analysis techniques and main components. The experiment was conducted at the Chão Nativo farm located in the municipality of Sinop, Mato Grosso, Cerrado-Amazonian ecotone. For this, a rectangular mesh was installed with 103 sampling points distributed in an area of 7.02 ha, in which the grain yield of the soybean was determined as well as the physical and chemical attributes of the soil in the layers 0-10 and 0.10 - 0.20 m. Soybean showed a grain yield between 2.83 and 3.70 Mg ha-1, which was positively correlated with the spatial distribution of pH, phosphorus and potassium. The soil presented low physical quality due to high soil resistance to penetration and macroporosity less than 10%; however, no spatial correlation of physical attributes with soybean yield was observed.

ABSTRACT The objective of this work was to evaluate seeds of cowpea, cultivar BRS Tumucumaque, subjected to different water stresses induced by polyethylene glycol (PEG-6000) and mannitol and different salt stresses induced by NaCl and CaCl2 solutions. The water and salt stresses was evaluated in laboratory using completely randomized experimental designs in 2x6 factorial arrangements, with six osmotic potentials (0.0, -0.2, -0.4, -0.6, -0.8 and -1.0 MPa) and two stress inducers for each experiment, with four replications of 50 seeds. The percentage of germination, germination speed index, root and shoot lengths and seedling fresh weight were evaluated at the tenth day (end of the evaluation period). The simulated water stress showed effects on the cowpea seed germination and seedling initial growth by decreasing the rates of the variables evaluated, which had greater effect in treatments with PEG-6000. The salt stress induced by NaCl showed greater effect on the variables evaluated than that induced by CaCl2, due to the sodium toxicity in the salt chemical composition.

ABSTRACT The use of elicitors in plants for disease control is demonstrated by the accumulation of phytoalexins. Among these elicitors, metabolic products from fungi have been shown to be effective in the activation of mechanisms of induced resistance. Thus, this study aimed to evaluate the effects of filtrates from the saprobic fungi Curvularia inaequalis, Pseudobotrytis terrestris, Memnoniella echinata and Curvularia eragrostidis in inducing phaseolin, glyceolin and deoxyanthocyanidins. For this, fungal mycelial disks were liquid-subcultured in potato dextrose (BD) media and maintained in BOD at 25 °C and 12 h of light and darkness. After 20 days, the cultures were filtered and, the filtrates were used in the experiments. Phaseolin was measured in etiolated hypocotyls of bean. For glyceolin evaluation, cotyledons of soybean were used. The deoxyanthocyanidin accumulation was evaluated in etiolated mesocotyls of sorghum. The results were subjected to analysis of variance and compared by regression tests (p < 0.05). The filtrates of the saprobic fungi C. eragrostidis, C. inaequalis, P. terrestris and M. echinata promoted 9, 8, 9 and 7% greater increases in the concentration of phaseolin accumulations, respectively. The glyceolin accumulation varied with the concentration of C. eragrostidis, C. inaequalis and P. terrestris by adjusting the behavior to a cubic model. The deoxyanthocyanidin accumulation increased with concentration, while the filtrates of M. echinata and C. eragrostidis promoted 2 to 3 times more increases than the application of water. The filtrates of P. terrestris, C. eragrostidis, C. inaequalis and M. echinata induced accumulations of phytoalexins in soybean, beans and sorghum.

Authors: Tischer Vinicius
Published: September 2017

Resumo O objetivo da pesquisa foi o de gerar uma base de análise quantitativa para subsidiar uma avaliação integrada da infraestrutura cicloviária inserida no contexto de mobilidade urbana das cidades. A metodologia utilizada deu ênfase a pesquisa e o desenvolvimento de parâmetros estatístico-matemáticos que explicitam a continuidade ou a fragmentação, densidade, e funcionalidade de um sistema cicloviário utilizando estudo de caso das cidades de Balneário Camboriú/SC e Itajaí/SC para validar os índices e parâmetros propostos. Ambas as cidades possuem um sistema implementado de infraestrutura cicloviário e projetos de expansão desta, o que facilitou a comparação entre elas. Os resultados obtidos mostraram-se positivos, com indicadores aderentes e sensíveis para a quantificação da qualidade do sistema cicloviário das cidades, subsidiando o planejamento urbano e adoção e monitoramento de metas. O desenvolvimento do IMCiclo (Índice de Mobilidade Cicloviária) permitiu, de forma objetiva e simplificada, classificar a qualidade do sistema cicloviário contribuindo para a difusão da necessidade de mensuração das condições da infraestrutura cicloviária. Foi possível observar claramente as diferenças entre as cidades estudadas, onde Balneário Camboriú atingiu os melhores índices.

A lição dos mestres: os parnasianos na biblioteca de Mário de Andrade
Authors: KIMORI LIGIA
Published: September 2017

RESUMO Em 1921, Mário de Andrade publica, no Jornal do Comércio, em São Paulo, “Mestres do passado”, série de artigos dedicada à análise dos principais parnasianos brasileiros, estudo aprofundado, longo, análise minuciosa que firma um leitor aplicado, capaz de discorrer sobre características dos poemas, de tecer comparações entre autores, pronto para apontar desajustes. A marginália desse leitor em Francisca Júlia, Raimundo Corrêa, Alberto de Oliveira, Olavo Bilac e Vicente de Carvalho vale, em certos aspectos, como o prototexto desse conjunto de artigos, importante contribuição do leitor crítico.

O fandango de chilenas e suas transformações no tempo
Authors: SANCHES BRUNO DE SOUZA
Published: September 2017

RESUMO O fandango de chilenas é um dos três tipos de fandangos que classificamos como “fandangos caipiras”. Esses foram ignorados pela maioria dos principais folcloristas brasileiros. Como consequência disso, não houve, além do trabalho de Rossini Tavares de Lima (1954) sobre os fandangos de chilenas, pesquisas relevantes do ponto de vista social ou musical sobre essas manifestações. Mostramos aqui a principal causa dessa lacuna bibliográfica e apresentamos uma breve descrição tanto do fandango de chilenas quanto das transformações que ocorreram com o passar do tempo, desde a última vez em que se falou dele com pertinência, a década de 1950.
Semi-empirical solutions for fractal-based hydraulic properties of 3D fracture networks

Published: September 2017

Semi-empirical solutions for fractal-based hydraulic properties of unsaturated three-dimensional fracture networks are presented, in which three assumptions are made: (a) the permeability is scale dependent, (b) each fracture cuts through the model and (c) the difference between fractal dimensions for fracture aperture distribution and tortuous length of a fracture is <1·7. The results show that the relationship between the relative permeability of the gas phase and saturation agrees well with those reported in the literature. The fractal dimensions for fracture aperture distributions of the fluid and gas phases are between 2 and 3. The permeability of the saturated fluid phase is influenced by the fractal dimension for the tortuous length of a fracture and maximum fracture aperture. With the increase in saturation, the variation range in fractal dimension for fracture aperture distribution of the fluid phase for different fracture porosities decreases; however, the variation range increases for different ratios of maximum aperture to minimum aperture. The permeability of both phases is more sensitive to the fractal dimension for the tortuous length of a fracture than to the fracture porosity and/or the ratio of maximum aperture to minimum aperture.
Did QE Lead Banks to Relax Their Lending Standards? Evidence from the Federal Reserve's LSAPs
Authors: Kurtzman Robert , Luck Stephan , Zimmermann Tom
Published: September 2017

Using confidential loan officer survey data on lending standards and internal risk ratings on loans, we document an effect of large-scale asset purchase programs (LSAPs) on lending standards and risk-taking. We exploit cross-sectional variation in banks’ holdings of mortgage-backed securities to show that the first and third round of quantitative easing (QE1 and QE3) significantly lowered lending standards and increased loan risk characteristics. The magnitude of the effects is about the same in QE1 and QE3, and is comparable to the effect of a one percentage point decrease in the Fed funds target rate.
