Published: March 2018

In the Mexican economy, particularly in the Soconusco region of Chiapas, the cultivation of coffee generates significant inputs; however, coffee plants are susceptible to pests and diseases, so it is necessary to reinforce its production through sustainable management. In this study, we searched for the native arbuscular mycorrhizal fungi (AMF) that could be used as biofertilizers in coffee cultivation. We collected 21 soil samples coming from seven coffee plantations (Coffea canephora) in the Soconusco region Chiapas, Mexico in November 2015. We isolated the spores of AMF by the wet sieving and decanting method to quantify their abundance, richness and composition of morphospecies, as well as their relationships with soil properties. A total of 20 morphospecies and five new records of AMF were obtained, and the most frequent genera were Acaulospora and Glomus. The Toluca and Victoria sites had higher morphospecies richness (17 spp. c/u) than San Agustín, November 20 and San Luis Nexapa (4-7 spp. c/u); while Providencia and Platanar sites recorded an intermediate richness and the highest values of spore abundance. The dissimilarity of Victoria and Toluca in its composition of AMF, respect to the other sites, was explained by the low concentration of PO4-3 in the soil. P availability, linked to soil acidity, is the factor that could be regulating the AMF communities in the soil of the rhizosphere of coffee trees at Soconusco. We consider that could have consortia of AMF specific for soil P-levels and acidity of coffee sites, i.e. Acaulospora and Glomus consortia, which are common into the environmental conditions of coffee plantations in México. Anyway, we need to examin deeply these strains to evaluate their compatibility and functionality before proposing them as native biofertilizers that promote the development and yield of coffee plantations in this tropical region of Mexico.

In wild animal species, the use of non-invasive and non-stressful procedures to determine hormone profiles, such as fecal steroid measurements, has considerably increased the comprehension of their reproductive physiology. Since there is limited information related to the reproductive hormone profiles of the two-toed sloth, Choloepus hoffmani, a study was conducted in captive specimens at the “Sloth Sanctuary” (Cahuita, Limón, Costa Rica), in order to determine: (i) the reliability of the fecal progesterone and estrogen extraction and its quantification with an AIA-360® analyzer, (ii) assess blood parameters in this species and (iii) evaluate if there is a correlation between fecal and plasmatic steroids. The study was performed over a three-month period, from November, 2013 to January, 2014, with a total amount of 208 fecal samples collected from five sexually mature females weighing 6.32 Kg in average. The average of the median concentrations of progesterone in feces of the five females was 124.21 ng/g, and 1 708.95 pg/g for estrogen. The average minimal and maximal values were 50.96 ng/g and 1 057.46 ng/g for progesterone and, 1 191.77 pg/g and 2 159.24 pg/g for estradiol. In plasma, progesterone median values were 1.26 ng/mL, showing a minimum of 0.32 ng/mL and 12.84 ng/mL as maximum values. The plasmatic estrogen levels were below the detection limit of the equipment (25 pg/mL). Although there was no strong statistical correlation between the fecal and plasmatic progesterone fluctuations, our data suggests that the plasmatic events are mostly reflected in feces two days afterwards. Also, the levels of progesterone were elevated during the first half of November and, subsequently, showed a successive and important reduction in all the females tested. Finally, our results demonstrated that fecal steroid extractions and their measurement in a AIA-360®, allowed the successful detection and represents an alternative non-invasive determination of hormone profiles in C. hoffmani.
Las pupas de Podonominae (Diptera: Chironomidae) de los ríos tropicales Altoandinos
Authors: Acosta Raúl , Prat Narcís
Published: March 2018

The Podonominae is a subfamily of Chironomidae which immature stages inhabit cold streams and brooks. In South America, most of the species have been reported only from the Andean/Patagonian subregion. However, the knowledge of its diversity from high tropical areas is still scarce. We studied the richness of genera and morphotypes of pupae and pupal exuviae of the subfamiliy Podonominae (Diptera: Chironomidae) in the high Andean rivers from Colombia, Ecuador and Peru, and discussed its geographical distribution in the studied area. The specimens were collected between 2004 and 2011 in 197 sampling points, from 17 basins over 2 000 m a.s.l. During the dry season, benthic and drift samples were taken in different substrates. We recognized three genera: Podonomopsis, Parochlus and Podonomus, with one, nine and 14 morphotypes, respectively. Only six of them were clearly determined as species previously described. Podonomopsis was represented only by one species, P. illiesi, only found in high altitude rivers in Perú (above 3 500 m a.s.l.). Morphotypes richness and abundance of Parochlus were higher in rivers from Ecuador and Colombia (P. incaicus, Parochlus sp. 1 and Parochlus sp. 2 were the most common species). Conversely, Podonomus was more diverse and abundant in rivers from Perú (P. caranqui, P. fittkaui and P. fastigians were the most common species). We found a clear pattern of distribution of morphotypes in the latitudinal gradient. First, we confirmed an evident decrease in the morphotypes richness in relation to the South Andes. Second, we found species such as Podomopsis illiesi, Podonomus fittkaui and Podomus fastigians that only were present in Perú, but not in Ecuador and Colombia. For these species, the Huancabamba Depression (6°S Latitude, North of Perú), a major structural and physiographic break in the Andes, could represent an important barrier in their dispersion toward lower latitudes. A taxonomic key to genera and morphotypes determination was also provided.
Transformaciones espacio-temporales de la cobertura vegetal en el Parque Nacional Corcovado, 1960- 2014
Authors: Morera Beita Carlos , Sandoval Murillo Luis Fernando , Pinto Fusaba Josep
Published: March 2018

Regional studies evaluating spatial-temporal transformations of vegetation in Costa Rica, especially within National Parks, are scarce. Therefore, this paper analyses the vegetation distribution during 1960, 1976, 1997 and 2014 in the Corcovado National Park. This protected area is located in the Osa Peninsula, Costa Rica, and represents the Northern most tropical rain forest on the Pacific coast of America. This area offers a great wealth of biodiversity due to its geological formation, isolation for long time periods, and its particular climatic conditions that generate unique ecosystems such as cloud forests associated with ocean situated close to hill breezes located over 500 m a.s.l., as well as dense tropical forest. This study evaluates the spatial distribution of vegetation based on maps that resulted from the process of photo-interpretation of 1960, 1976, 1997 and 2012, as well as from the landscape index analysis. It concludes that during the study period, the vegetation changes have been minimal. Instead, in the few areas impacted by human activity (small-scale agriculture and pasture lands) an ecological restoration has occurred during recent decades. In addition, this research suggests that the recovering forest cover within the park and even within the Osa Peninsula has been expanding the cloud forest. An increase and contraction relationship between the different categories (Cloud forest and forests as well of flooded forest and forest in flat zones) was found. Furthermore, this study suggests the need of permanent plots in order to monitor vegetation and identify the factors that explain this previous process.
Hábitos alimentarios de quironómidos (Diptera: Chironomidae) en lagos del páramo de Chingaza, Colombia
Authors: Caleño Ruiz Yulibey , Rivera Rondon Carlos Alberto , Ovalle Hernando
Published: March 2018

Tropical high mountain lakes show unique environmental conditions where chironomids play an important role in ecosystem functioning. The characteristics of these environments could favor diet overlap and therefore a high interspecific competition. This study described the dietary habits of chironomid genera, identified whether the dietary habits were specialized or generalist, and analyzed the diet overlap in the genera. Chironomidae larvae were collected from four lakes of the Chingaza paramo during the dry season, between April and May of 2 016. The feeding habits of larvae were evaluated by analyzing gut contents following standard methods. Each genus was assigned to trophic guilds (carnivore, detritivore and algivore) and the diet overlap was estimated using the Pinka's index. A total of 1 003 individuals were collected and nine genera were identified. Larvae consumed mainly fine particulate organic matter (FPOM), algae, macrophyte fragments, macroinvertebrates, and animal tissues. FPOM was the main feeding resource of detritivores. The analysis of diets showed a high affinity of each genus for a single trophic guild and most of the genera were generalist in the use of resources. For all lakes, high levels of diet overlap were observed among genera and trophic guilds, mainly among detritivores. Our results suggested that Chironomidae larvae of these lakes presented well differentiated trophic habits, and showed a moderate diet overlap within detritivores and carnivores.
La importancia del sistema activador de plasminógeno en la patogénesis y progresión del cáncer gástrico

Published: March 2018

Gastric cancer is ranked as the third death-causing cancer and one of the most incident malignancies worldwide. Although Helicobacter pylori is the most well-established risk factor for the development of this neoplasm, most of the infected individuals do not develop gastric cancer. Two of the main challenges faced by the world’s scientific community in the combat against gastric cancer are the unraveling of its pathogenesis and the identification of novel ways to bring down the mortality. Malignant cell invasion of the non-neoplastic adjacent tissue and metastasis are pivotal events during cancer development and progression. Both processes are facilitated by proteases capable of degrading components of the extracellular matrix, some of which have been associated to clinico-pathological aspects of the disease. Recent studies have suggested the possible connection between H. pylori and the expression of some of these proteases in gastric mucosa. This review summarizes the current knowledge about epidemiological, clinical and biological aspects of gastric cancer; it also discusses the main findings about the involvement of the plasminogen activation system in the development and progression of this disease, as well as its potential repercussions in the clinical setting.
Third Argentine record of Eurhopalotrhix bruchi (Santschi, 1922) (Hymenoptera, Formicidae), description of an interomorphic queen and the colony, and notes on biology and ecology
Authors: Arcusa Juan M. , Cicchino Armando C.
Published: March 2018

Eurhopalothrix bruchi is the only species of the genus present in Argentina. We present only the third record of this species from Argentina and describe for the first time the female and characteristics of the colony. The nest collected had 48 workers, 6 queens, and 4 pupae. The queens are characterized as wingless, without wing sclerites, and worker-like. The scarcity of pre-imaginal stages suggests that fission of the colony led to the nest’s foundation.

This article was migrated. The article was marked as recommended. Study problemThe training of postgraduate medical students in the multi-racial landscape of South Africa has faced challenges given the need for relationships in personal mentoring and learning through legitimate participation in the community of practice (CoP), as part of cognitive apprenticeship training. A high failure rate in the exit examination had stimulated interest into understanding the nature of the learning environment.Aim and objectivesThe study explored conceptions of former students in a medical specialty program regarding the nature of racial and socio-cultural diversities in their learning environment, influences on learning, and how they responded to them.MethodologyA qualitative enquiry using in-depth interviews with semi-structured open-ended questions and thematic analysis with a social constructionist approach of epistemology used for data analysis and interpretation.FindingsStudents conceived race, language, departmental culture and social identity as barriers in their learning. The lack of structured formative training with feedback, evaluation, personal mentoring, and supervision also emerged. Through resilience, adaptability, and maturity qualified students overcame these difficulties.ConclusionCurrent and future students may benefit by developing resilience when dealing with racial and socio-cultural differences, and findings support the inclusion of cultural competence and a multi-lens approach in medical specialty curricula.

Published: March 2018

This article was migrated. The article was marked as recommended. Receiving feedback is an essential component of learning and can be invaluable to help you improve your knowledge and skills as you progress towards qualification as a doctor. Whilst formal feedback from assessments is commonplace, it can be daunting to approach others to provide you with feedback. Furthermore, it can be difficult to know how to act on the feedback once you have received it. In this article we look at how best for medical students to ask for feedback and act on the advice which is given to them with a unique point-of-view provided from a current clinical teaching fellow.
Evaluation of flexible pavement construction cost according to the design method
Authors: Tsiknas Anastasios , Athanasopoulou Adamantia , Papageorgiou Grigorios P.
Published: March 2018

The aim of this paper is to propose a cost-optimal design method for flexible pavements based on specific design parameters, in compliance with Greek and European technical regulations and standards regarding roadworks. Three design methods for flexible pavements that are most commonly used in Greece were evaluated, namely the Asphalt Institute (AI) method, the British design method and the method of Egnatia Odos (EO). The first two methods are used worldwide whereas the EO method was developed by Greek designers and has found wide application in Greece and neighbouring countries. The design parameters evaluated in this study were traffic volume, subgrade soil bearing capacity and air temperature. In most of the examined design scenarios, the AI method was found to offer the lowest-cost design solution for flexible pavements. However, the British design method provided a reduced-cost solution taking pavement thickness into account for heavy or very heavy traffic loads and a poor-quality subgrade soil. If the design case is a road with heavy traffic load and good-quality subgrade soil, the EO method produced the lowest cost for a flexible pavement.
Utilidad de los métodos inmunológicos y moleculares para el diagnóstico del virus del Chikungunya
Authors: Chaverra Mendoza Irides
Published: March 2018

Introducción: Chikungunya es un virus que ha ocasionado muchos brotes infecciosos a nivel mundial convirtiéndose en un problema de salud pública. Comparte varias similitudes con el virus del Dengue, son transmitidos por el mismo vector que es un mosquito del género Aedes, se encuentran en zonas tropicales y subtropicales y presentan la misma sintomatología clínica en la fase aguda de la enfermedad, lo que dificulta su diagnóstico clínico. Métodos: Revisión bibliográfica de los métodos diagnósticos del virus a partir de la literatura mundial en buscadores de base de datos y revistas indexadas Discusión: Entre los resultados se puede decir que de todas las técnicas inmunológicas los formatos de MAC ELISA para detección de anticuerpos y los ELISA para detección de antígenos muestran resultados confiables para la identificación del virus,con respecto a las pruebas moleculares se puede afirmar que son técnicas altamente sensibles y específicas, con múltiples ventajas sobre las técnicas inmunológicas ya que pueden detectar y cuantificar ambos virus en forma simultánea. Conclusión: Las mejores técnicas son las pruebas moleculares, pero es muy costosa para la mayoría de los laboratorios, por tanto, se recomienda el uso de ensayos de ELISA basados en detección de antígenos debido a que son específicos, sensibles y pueden detectar al virus en la fase aguda de la enfermedad.

Objective: To determine the prevalence of hypercementosis in a Saudi Arabian population. Material and methods: A total of 642 CBCT scans from patients comprising 4471 teeth were incorporated in the study sample. All teeth were analyzed for the presence of hypercementosis in sagittal, axial and coronal plains by two qualified and experienced observers. The characteristics of the involved tooth in terms of gender, jaw and location were recorded from the CBCT scans. The obtained data were statistically analyzed using SPSS 21.0. The reliability of measurements was evaluated by kappa statistics. Results: Out of total 642 subjects hypercementosis was observed in 31 patients (4.82%) and 43 teeth (0.96%). Eight (2.68%) maxillary 1st molars, 6 (1.88%) mandibular 1st molars, 5 (1.46%) maxillary second molars, 7 (1.95%) mandibular 2nd molars, 9 (4.76%) maxillary 3rd molars and 8 (3.58%) mandibular 3rd molars were observed to have hypercementosis. Among males, 4.76% were affected with hypercementosis as compared to 4.86% of females (p=0.97). Likewise, no significant difference in the occurrence of hypercementosis was observed between maxillary and mandibular arches or between sides (p>0.05). Conclusion: The prevalence of hypercementosis in a Saudi population was found to be 4.82% with respect to patients and 0.96% with respect to teeth. No significant propensity for gender, jaw and arch side was noted.

The protocol describes guidelines and steps for taking repeated stabilometry measurements. The parameters calculated from repeated measurements can be user for reliability analysis of certain center of pressure parameters used to describe postural control and balancing capability. The guidelines are based on recommendations of the literature. It is important to be consistent during all the measurements and follow the guidelines as they regulate important aspects of the measurements. The changes of these aspects can signifficantly alter the motion of the center of pressure.

Published: March 2018

Menopause is characterized by abnormal oestrogen levels. In our preliminary research, we identified that Cistanche deserticola exerts oestrogenic effects, and hypothesized it to be because of its glycoside constituents. In this study, we orally administered C. deserticola total glycosides (CDTG) daily at a dose of 1.5 g/kg body weight to sexually immature female Kunming mice. The negative and positive control groups received equal volumes of distilled water and diethylstilboestrol solution, respectively. On the fifth day, blood samples were collected, and the uteri were immediately excised and weighed. Proliferation of MCF7 cells was evaluated after they were exposed to the serum from each group of CDTG-treated mice. We used cluster analysis to distinguish the CDTG samples collected from 10 different sites. Further, 43 glycosides were identified in CDTG by UPLC/Q-TOF-MS. Finally, principal component, Greyrelativity, and bivariate correlation analysis were used to identify eight components that contributed to the oestrogenic activity of CDTG; they were sinapaldehyde glucoside, salidroside, syringin, dehydrodiconiferyl alcohol-4-O-β-D-glucoside, echinacoside, ononin, bartsioside, and kankanoside I. Among them, sinapaldehyde glucoside, syringin, dehydrodiconiferyl alcohol-4-O-β-D-glucoside, bartsioside and kankanoside I are first reported as oestrogenic active glycosides. Further studies are required to investigate the in vivo activity and safety of the identified components.
Teaching in the Restorative Window: Authenticity, Conviction, and Critical-Restorative Pedagogy in the Work of One Teacher-Leader
Authors: FINE SARAH M.
Published: March 2018

In this article, Sarah M. Fine uses portraiture to explore the undertheorized question of what it means to teach in ways that align with the values of the restorative justice framework. The piece centers around the work of Nora, a veteran teacher-leader who explored this question in the context of her own classroom and, as a result, shifted her practice in significant ways, making it more deliberate in its attention to students' social-emotional needs, more project based in its design, and more critical in its stance. In turn, these shifts helped restore and transform students' relationships to the content under study, as well as to each other and to Nora. This portrait provides a richly textured picture of what it means to be—and become—a restorative teacher and suggests that there are powerful synergies between the restorative justice frame-work and the tradition of critical pedagogy.

The trunk muscles behavior in women with low back pain in the test of flexion and extension of the trunk
Authors: Nava Guilherme Thomaz de Aquino , Tozim Beatriz Mendes , Morcelli Mary Hellen , Navega Marcelo Tavella
Published: March 2018

INTRODUCTION: Chronic low back pain has a direct repercussion on the activities of daily living and the alteration of motor control is its main cause. This change leads to instability of the trunk stabilizer systems that control movements. Trunk flexion and extension movements associated with external disturbances may increase the potential for motor control error, resulting in injury and pain. OBJECTIVE: To evaluate and compare the recruitment of the trunk stabilizer muscles, with and without load, in the flexion and extension movements of the trunk. METHODS: Thirty - four sedentary women were evaluated, aged between 30 and 59 years, divided into: low back pain group (LBPG n = 19) and control group (CG n = 15). The protocol consisted of clinical evaluation, pain evaluation, strength test of extensor trunk muscles and trunk flexion and extension tests (TFET). Muscle electromyography in internal oblique (IO), lumbar multifidus (LM), rectus abdominis (RA), external oblique (EO) and lumbar iliacus (LI) were performed simultaneously. Multivariate analysis of variance was used with two-way repeated measurements. RESULTS: LBPG presented a trend of greater recruitment in all muscles and loads evaluated, with muscle activation up to 47% higher when compared to CG. In the intergroup comparison, the global muscles demonstrated a tendency for greater activation in LBPG, with values up to 53% higher when compared to CG, and predominantly high effect size d> 0.80. In the intragroup comparison, the IO, EO, LI and LM muscles of the LBPG presented ascending muscle recruitment with increased load the opposite was seen in the CG, which showed increased activation only in the LI and LM muscles. CONCLUSION: Women with low back pain need more muscle recruitment to remain stable and, in challenging situations, use inefficient strategies.

Tradução do prefácio do livro Look to the mountain – an ecology of indigenous education, de autoria do educador indígena Gregory Cajete, do pueblo de Santa Clara, no estado do Novo México, nos Estados Unidos. Em seu prefácio, Cajete traça os parâmetros e processos que subjazem à sua proposta, que destaca a importância de uma abordagem inclusiva da natureza num processo que tem como base uma “ecologia da educação indígena”, e sugere a investigação de uma alternativa educacional contemporânea para os povos indígenas fundamentada culturalmente na concepção dos povos tradicionais. Segundo o autor, seu livro se configura enquanto uma tradução de princípios de uma educação voltada a um quadro contemporâneo do pensamento. Seu projeto de educação como comunicação intercultural se apresenta como uma metáfora alternativa diferente da que se pratica hegemonicamente na América. Tradicionalmente, os índios veem a vida através de uma metáfora cultural diferente. É esta metáfora cultural diferente que emoldura a exploração da filosofia educacional indígena apresentada no livro.
Esse tal de final feliz
Authors: Velázquez Carlos
Published: March 2018

O mito do herói remonta as épocas mais remotas da humanidade e reflete a batalha dos sujeitos na busca criativa por profundidade em sua integração com o real. O arquétipo do herói tem sempre nos acompanhado nos mitos, nos relatos fantásticos e na literatura, entretanto, mais recentemente, sob o desenvolvimento da cultura industrial, este arquétipo foi renovado: recebeu super-poderes e identidade secreta. Este herói-super-produto carrega atualmente o papel de messias salvador e guardião do happy end, transformando, com seus super-poderes, sua própria presença e função arquetípicas. Sob auspício da metodologia de pesquisa qualitativa de paradigma junguiano, com recurso a um conjunto bibliográfico e documental de ordem multidisciplinar, analisamos esta transformação a fim de fundamentar nossas especulações sobre suas possíveis consequências.
Por um Eros furioso e terno: Uma abordagem poética contemporânea do mito de Eros no livro Bolha de luz, de Hermínio Bello de Carvalho
Authors: Cruz Marcelo Maldonado
Published: March 2018

O mito de Eros encontra-se nas raízes das investigações a respeito do sentimento do amor e das maneiras como se exprime no homem. Tal como idealizado por Platão em O banquete, ressurge representado através dos tempos em praticamente todas as manifestações artísticas ocidentais, principalmente na poesia. Hermínio Bello de Carvalho, poeta carioca, vai retomar, no livro Bolha de luz, de 1985, o Eros socrático e conferir-lhe uma identidade contemporânea, transfigurando-o na imagem do marginal terno. Ao analisar as imagens integrantes do discurso poético à luz dos pressupostos teóricos desenvolvidos por Gilbert Durand, chega-se uma releitura do mito de Eros na qual se verifica uma profunda identificação com a vigência do regime noturno do imaginário simbólico do homem.

Pelas tramas do Quibungo
Authors: De Souza Josiley Francisco
Published: March 2018

É possível estabelecer relações entre o ato de produzir textos escritos e o exercício de tecer, que se revela na própria etimologia das palavras texto e tecer, afinal, sabemos, que tecer provém do latim textum, que significa tecido, entrelaçamento. Como o artesão que entrelaça as tramas de seu trabalho-arte, o escritor trabalha a língua para nela inscrever sua voz. No entanto, muitas vezes na educação básica, ausenta-se essa tessitura. E se o artesão tem como matéria-prima fios de algodão, vime ou outros, esse escritor, às vezes ausente na escola, talvez possa lançar mão de narrativa orais. Um exemplo pode ser apontado com transcriações de contos orais afrobrasileiros envolvendo o Quibungo. A presença africana pode ser observada no próprio nome do personagem, que revela diálogos entre o português e línguas banto. Histórias do Quibungo integram um corpus de contos orais que vem sendo objeto de reflexões no projeto Vozes africanas nas Américas: a palavra banto em contos orais afrobrasileiros e afrocubanos, desenvolvido por Josiley Francisco de Souza, na Faculdade de Educação da UFMG. No contexto escolar, essas narrativas podem promover trabalhos que envolvem diálogos transculturais entre língua portuguesa e línguas banto, entre culturas orais e escritas, entre histórias e memórias africanas e afrobrasileiras historicamente silenciadas.
Ficção científica encontra o pós-modernismo: Slipstream
Authors: Pereira Valéria Sabrina
Published: March 2018

Em 1989, ao observar o crescente número de romances de autores aclamados pela crítica literária que apresentavam traços de ficção científica, o escritor de ficção científica Bruce Sterling levantou a hipótese de que um novo gênero estaria nascendo, o qual ele denominou de slipstream. Um quarto de século depois, o termo se disseminou entre os leitores de ficção científica, sem, todavia, conseguir encontrar uma definição clara de qual seria o seu objeto. Este artigo discute se é realmente necessário falar de um novo gênero, e aborda os problemas da teoria da ficção científica, que são parcialmente responsáveis pela impossibilidade de um diálogo junto aos teóricos das outras áreas da literatura.

Este trabalho tem como objetivo apresentar uma discussão sobre o diário de Drummond, intitulado O observador no escritório, demonstrando como a obra transcende as questões do gênero, já que não se configura como um diário convencional, indo além dos registros mais íntimos e das reflexões do dia a dia. O livro reúne registros de fatos políticos, literários e pessoais datados de 1943 a 1977, publicados no Jornal do Brasil em 1981-1982 e, organizados pelo autor, em 1985. Por ir além dos registros pessoais, recortando da história aquilo que o poeta acreditava ser essencial para traduzir sua época, ao falar de si e dos outros, o diário de Drummond, revela-se como uma heterobiografia. Sendo assim, essas anotações que se aproximam ora da crônica, ora da escrita íntima, ora do registro histórico e documental fazem deste diário um livro precioso no qual o leitor encontrará “um tempo filtrado pelo modo de ver” do observador.

A independência é um modo de produção
Authors: Oliveira Alice Bicalho de
Published: March 2018

A forma do livro se modifica continuamente, seja no plano diacrônico seja no sincrônico. Tanto quanto ele, os modos de editar são múltiplos e fluídos no que diz respeito às técnicas de impressão, trato com a linguagem, relações de trabalho e comerciais, distribuição etc. A partir de quais critérios, então, estabelecer uma diferenciação entre um modo padrão de edição e modos independentes? Haveria questões e valores que pautariam um modo e não outro? Poderíamos ainda, mais profundamente, estabelecer semelhanças entre modos de trabalho e produtos finais às vezes tão distintos quanto um best-seller e um livreto mimeografado? Neste artigo buscamos alguns parâmetros para pensar a edição independente, indo na direção da economia do livro, mas, principalmente, no modo de se organizar cada etapa de sua cadeia produtiva.
ULUSLARARASI ÇEŞİTLENDİRMENİN PORTFÖY PERFORMANSINA ETKİSİ: GELENEKSEL VE İSLAMİ HİSSE SENEDİ PİYASALARI İÇİN AMPİRİK BİR UYGULAMA
Authors: UYSAL Mustafa , EMİR Mustafa
Published: March 2018

Bu çalışmada Türkiye’de yatırımda
bulunan bir yatırımcının İslami hisse senedi endekslerinden optimal portföy
oluşturmak suretiyle yapmış olduğu uluslararası çeşitlendirmenin geleneksel
hisse senedi endeksi ile performans ve risk açısından farklılık gösterip
göstermediği araştırılmıştır. Araştırmada 2002:06-2016:10 yılları arasındaki aylık
İslami hisse senedi endeks verileri kullanılmıştır. Piyasaların durağanlığı
Carrion-i Silvestre (2009) birim kök testi ile,eşbütünleşme ilişkisi ise Maki
(2012) eşbütünleşme testi ile analiz edilmiş ve Markowitz ortalama varyans
modeline göre portföyler oluşturulmuştur. Çalışma sonunda, 2008 küresel
finansal kriz öncesi ve 2008 küresel finansal kriz döneminde İslami hisse
senedi piyasalarının geleneksel hisse senedi piyasalarına göre daha iyi bir
performansa sahip olduğu buna karşın 2008 küresel finansal kriz sonrası dönemde
ise geleneksel hisse senedi piyasalarının İslami hisse senedi piyasalarından
daha iyi performansa sahip olduğu görülmüştür. Ayrıca çalışmanın tamamında
İslami hisse senedi piyasalarının geleneksel hisse senedi piyasalarına göre
daha düşük riske sahip olduğu dolayısıyla özellikle ekonominin duraklama ve
çöküntü dönemlerinde yatırımcısına riske karşı bir koruma sağladığı yani
güvenli bir liman özelliği sunduğu tespit edilmiştir.

Taşımacılık
sektörünün önemi hem Dünya’da hem de Türkiye’de her geçen gün artmaktadır.
Küreselleşmenin etkisiyle müşterilerin ürünleri daha hızlı ve eksiksiz bir
biçimde talep etmelerine paralel olarak, işletmelerin ve tedarik zincirlerinin
de rekabet edebilmek için sahip oldukları lojistik hızları ve operasyonel
mükemmeliyeti artırmaları zorunlu hale gelmiştir.  Daha da önemlisi, tedarik zincirleri yetersiz
kalan uygulamalarını güncellemek ve her zaman rekabette kalmalarına olanak
sağlayacak yeni yollar ve yöntemler bulmak zorunda kalmaktadırlar. Bu kapsamda,
intermodal taşımacılık yeni bir lojistik uygulama olarak giderek önem kazanmaya
başlamıştır. Bunun yanı sıra taşıma türleri ve altyapılar arasında entegrasyon
intermodal taşımacılığın etkinliği ve verimliliği açısından son derece
önemlidir. Bu çalışmada Karadeniz limanlarının intermodal taşıma sistemine
entegrasyonu ve denizyolu taşımacılığı ile diğer taşıma türleri arasında bir
koordinasyonun sağlanıp sağlanamayacağı ekonomik faktörler de göz önüne alınarak
değerlendirmeye çalışılmıştır. Çalışmada Karadeniz limanları üzerinden
gerçekleştirilecek intermodal bağlantılar sayesinde oluşturulacak çok modlu taşıma sistemleri “multimodal” ile
tek modlu taşıma sistemlerinin etkinlikleri ve verimlilikleri lojistik
maliyetler açısından değerlendirilmiş, bu kapsamda Karadeniz limanlarının
intermodal ve kombine taşımacılık sistemlerine uyguluğu gözden geçirilmiştir.

Authors: T. Varija , C. M. Veerendra Kumar , Tarihalli Chandrasekhar
Published: March 2018

Background: The caesarean section (CS) delivery rate is steadily increasing worldwide, including India. Identifying the proportion of women in various categories as per Robson's ten group classification system and CS rate among them is important to bring down the increasing CS rate.Methods: This case series study was conducted at Vijayanagar Institute of Medical Sciences (VIMS), a tertiary care teaching hospital in Ballari, Karnataka, India. All pregnant women who have been admitted for delivery were enrolled and the data was collected for the women delivered by CS during January 2016 to December 2016 and proportions in various groups as per Robson’s ten-group classification system were calculated.Results: Among a total of 6980 women delivered during study period, 2992 (42.8%) delivered by CS. The CS rates among various groups varied from 100% among women with abnormal lies and group 6-95% (all nulliparous breeches) group 5-94% (Previous CS, single cephalic, >37 weeks) to 10 to 15% among multiparous women with spontaneous labour having single cephalic pregnancy (group 3). Among women with previous section, CS rate was very high (89.6%). Women with previous CS (group 5) contributed maximum (40.24%) to the total number of CS.Conclusions: In the present study, all women with breech presentation and abnormal lies delivered by CS and repeat CS was the highest contributor to all CS deliveries.

В данном исследовании рассматривается вопрос о том, в рамках какой логики действуют и принимают решения студенты-предприниматели в университете, цель которого связана с развитием, в частности, предпринимательского направления. Для проведения исследования использовался кейс-метод. Рассматривался множественный кейс включающий в себя три случая студентов-предпринимателей из Дальневосточного федерального университета (ДВФУ) в г. Владивосток. Данные для описания контекста исследования были получены из новостей и документов, находящихся в открытом доступе на официальном сайте ДВФУ. Данные для анализа кейсов были собраны с помощью полуструктурированных интервью, проведенных в мае 2017 года. По итогам анализа собранных материалов мы пришли к выводу, что студенты-предприниматели склонны следовать эффектуационной логике принятия решений. В рассмотренных случаях эта логика наиболее ярко проявляется в применении ресурсоориентированного подхода и принципа «синица в руке».
Combined treatment of toxic cyanobacteria Microcystis aeruginosa with hydrogen peroxide and microcystin biodegradation agents results in quick toxins elimination
Authors: Dziga Dariusz , Maksylewicz Anna , Maroszek Magdalena , Marek Sylwia
Published: March 2018

In some conditions the growth of toxic cyanobacteria must be controlled by treatment with algicidal compounds. Hydrogen peroxide has been proposed as an efficient and relatively safe chemical which can remove cyanobacteria from the environment selectively, without affecting other microorganisms. However, the uncontrolled release of secondary metabolites, including toxins may occur after such a treatment. Our proposal presented in this paper is fast biodegradation of microcystin released after cell lysis induced by hydrogen peroxide. The effectiveness of both Sphingomonas sp. and heterologously expressed MlrA enzyme in the removal of the toxin from Microcystis aeruginosa culture has been investigated. The results indicate that neither Sphingomonas cells nor MlrA are affected by hydrogen peroxide in the concentrations which stop the growth of cyanobacteria. A several-fold microcystin reduction was documented in the presence of these agents with biodegradation ability. Our results provide evidence that such a combined treatment of water reservoirs dominated by microcystin-producing cyanobacteria may be a promising alternative which allows fast elimination of toxins from the environment.

Authors: Ramdan Iwan M. , P Novita Anggun , F Ade Rahmat
Published: March 2018

Introduction: Pneumonia is still a global health problem especially in developing countries because it is the leading cause of death in children aged under 5 years old. In Indonesia the incidence of children pnemonia is still high.

Material and methods: The risk factors of pneumonia studied consist of house temperature, lighting, house humidity, occupancy density, exposure to cigarette smoke, and family disease history. Temperature and humidity of the house were measured by heatstress monitor, room lighting was measured by lux meters, the occupancy density was measured by direct observation, exposure to cigarette smoke and family disease history were measured by questionnaire. Data analysis using odds ratio and chi square.

Results: Obtained by the value of odds ratio: room lighting (OR = 3.18), cigarette smoke exposure (OR = 10.45), home temperature (OR = 0.337), humidity (OR = 0.192), occupancy density (OR = 0.214), and family history of disease ( OR = 0.753). Humidity (p = 0.024) and occupancy density (p = 0.028) associated with pneumonia.

Conclusion: Room lighting and exposure to cigarette smoke is a major risk factor for the occurrence of pneumonia in children aged under 5 years in Samarinda, the incidence of pneumonia is significantly related to house humidity and occupancy density.
Análisis constitucional de los derechos personalísimos y su relación con los derechos del buen vivir en la Constitución de Ecuador
Authors: Galiano Maritan Grisel , Tamayo Santana Gabriela
Published: March 2018

Los derechos de la personalidad son considerados por la doctrina mayoritaria como genuinos derechos subjetivos de carácter civil. De esta manera, se fundamenta su consideración como derechos fundamentales, y nos planteamos su relación con la novedosa cosmovisión que entraña el buen vivir (sumak kawsay) consagrado en la Constitución ecuatoriana de 2008. Se trata de un principio constitucional que, a través de una serie de derechos y garantías de índole social, económica, ambiental y política, sin duda, orienta al Estado, el Gobierno y el pueblo ecuatorianos hacia la consecución del sumak kawsay. De ahí la pertinencia de valorar la protección constitucional de los derechos personalísimos desde el prisma de este principio rector.
Frederic Bastiat: Hukukun Yozlaşması ve Liberal Yaklaşım
Authors: Tosun Cengiz Mesut
Published: March 2018

Frederic
Bastiat’a göre, hukuk devlet eliyle yozlaşmış ve yasal bir soygun mekanizması
haline gelmiştir. Bu anlayışı refah devleti diğer bir ifadeyle sosyal devlet
kavramı üzerinedir. Sosyal ve ekonomik hakların genişletilmesinin yolu, iktidarın
oluşturacağı yasalar çerçevesinde vergilendirme ile mümkündür. Bu süreç Bastiat
için yasal soygun ve yolsuzluk anlamına gelirken aynı zamanda hukukun
yozlaşmasıdır. Hukuk, adaleti tesis etmesi gerekirken, bazı gruplara çıkar
sağlama aracı haline dönüşmekte ve bu yasalarla meşru hale gelmektedir. Liberal
gelenek bu durumu özel mülkiyetin, emeğin hırsızlığı olarak görmektedir.
Devletin faaliyet alanı güvenlik ve adaleti sağlamak ile sınırlanmalıdır.
Hukukun yozlaşmasının, diğer bir ifadeyle yasal soygunun temel nedeni bilinç
eksikliğidir. Siyasal gücü eline geçirenlerin iki seçeneği vardır: Ya bu
soygunu durdurmak ya da bu süreci ortak olup sürdürmek. Tercih bu soygunu
durdurmak yönünde bir bilinçlenmeyi gerektirmektedir. Yasa yapıcının etkinlik
alanı güvenlik ve adaleti sağlama ise sınırlı olmalıdır.
El cambio de nivel: todo un desafío
Authors: Berger Lili , Jones Jennifer
Published: March 2018

El presente trabajo de investigación intenta poner de manifiesto nuestra preocupación por el pasaje de un nivel a otro en el sistema educativo, en especial el cambio que se produce entre el Nivel Inicial y la Educación Primaria. Es indudable que son muchos los factores que acompañan el cambio del niño de un nivel a otro, algunos de ellos inciden positivamente y otros lo hacen negativamente. No todos los niños viven este pasaje de la misma manera lo que incide en su adaptación e integración posterior. Nos inquieta entender cómo se opera esta transición, los cambios que se producen en este pasaje y en qué medida se atienden las características, necesidades e intereses de los niños.
