Portrayals of Caring Masculinities in Fiction Film: The Male Caregiver in Still Mine, Intouchables and Nebraska.
Authors: Araüna Núria , Tortajada Iolanda , Willem Cilia Margareta
Published: June 2018

This article analyzes the male caregiving characters Driss in Intouchables (2011), Craig in Still Mine (2012) and David in Nebraska (2013) in terms of hegemonic masculinity and its variations (Connell 1990; Connell and Messerschmidt 2005). Caregiving is a complex social situation normally assumed within kinship relationships, and traditionally attributed to women. We briefly review feminist analysis of caregiving since the 1970s (Fine and Glendinning 2005), and use critical studies on men and masculinities to show that the uptaking of caring tasks by men would and is contributing to equality between women and men (Elliott 2015).  We have looked at the portrayal of the male caregivers in these films, and if and how they challenge hegemonic masculinity in terms of positive experiences. Our findings show that despite the tension men experience between giving in to and challenging patriarchal privilege of a care-free life, strategies such as humour, complicity, outdoor action and a general concern for the dignity of the care-receiver can be identified as some of these features of (imagined) caring masculinities and open new spaces for defining care as a gender neutral activity.
Male Directed Sexual Violence in Conflict: A Challenge for Gender Studies
Authors: O'Mochain Robert
Published: June 2018

In recent years, extensive empirical data has indicated that acts of severe sexual assault are being perpetrated against large numbers of men in many areas of conflict around the world. In spite of such data, recognition of this problem within gender studies remains limited. This is due to many reasons including the opposition of a variety of feminism that is reluctant to acknowledge male victimhood. This paper argues that feminist reservations about a focus on male-directed sexual violence in conflict are unfounded, especially as adherence to dichotomous gender models of “male equals perpetrator/female equals victim” ignores the comparable suffering of male survivors. A feminist analysis is enriched and complemented by a focus on male survivors and on the gendered power relations that operate among men.
Masculinities: Tracing the Trajectories of Gender Performance in Afghanistan War Poetry
Authors: Haq Inam Ul , Rashid Uzma
Published: June 2018

This paper critically examines the war songs and poems of men who fought in the post 9/11 Afghanistan war. The study locates the analysis within the socio-cultural influences that left an impact on the ‘manly’ soldiers, allowing a 'micro mapping' of masculinity to be revealed in these men’s writings. Using thematic analysis techniques, fifty war songs and poemsfrom the years 2007 and 2008 are analyzed through the lens of masculinity and its performance. The critical investigation of the war songs and poems found that the performative dimension of masculinities in war spread around the themes of youth warriors; weapons; arms and war machinery; state of politics and need for an Islamic government; the motif of red color; and glorification of death. The religion Islam, their homeland Afghanistan and its traditional culture constantly act as a fuel to evoke overpowering emotions for the soldiers and their passion for fighting. It is furthermore found that the locally constructed masculinities informed the context ofthe Afghanistan War. This has implications for the way we understand masculinities especially in war poetry. As the paper demonstrates, the multiple ways in which the notion of masculinity is manifested in war poems point to the need to break free from the stereotypical understandings of warriors from conservative religious backgrounds.
Yes or No? Older people, politics and the Scottish Referendum in 2014
Authors: Crowther Jim , Boeren Ellen , Mackie Alan
Published: June 2018

In this article we report on the issues, experiences and patterns of response to the independence referendum with particular reference to older voters. By older voters we are referring to the 61+ age group, although information cited from different opinion polls can refer to slightly different age ranges. We interpret the data through the lens of informal learning, that is, by understanding the referendum as a process of action and reflection that developed as people engaged with the arguments through different media and educative experiences in everyday life environments. Our view differs markedly from the dominant narrative applied to explain the pattern of voting amongst older members of the Scottish electorate.
Well-being of older persons in Central and Eastern European countries
Authors: Antczak Radoslaw , Zaidi Asghar
Published: June 2018

Â Central and Eastern Europe is a unique region in terms of its social, economic anddemographic trends, particularly because of legacy of the communist system andtransformation to a market system. The transition coincided with a rapiddemographic change in which younger generation was able to reorganise themselvesrelatively easily whereas older people found this change much more difficult. Thispaper builds a picture of well-being of older population in eight Eastern Europeancountries: Albania, Armenia, Georgia, Moldova, Montenegro, Serbia, Turkey andUkraine and compares it to eight other European Union (EU) member States of thesame region. We used the Global AgeWatch Index â€“ an analytical framework ofZaidi (2013 ) offering comparative analysis of older peopleâ€™s well-being across theworld. It is extended by gender-specific analysis for two domains: health status andcapability. The results show that the combined Index value of eight Eastern andSouth-Eastern non-EU countries is considerably below the average observed foreight EU member States, however, in some individual indicators, some of the non-EU states performed better than the EU countries. The evidence summarised can beused to assess the position of the region and points to areas where policy changes arenecessary.
Religious vs Secular volunteering motivations: A study on European elders
Authors: Ariza-Montes Antonio , Tirado-Valencia Pilar , FernÃ¡ndez-RodrÃ­guez Vicente , Hager Mark
Published: June 2018

The reality of volunteering is highly complex. This concept is difficult to define and typify because of the great variety of interpretations, motivations, socio-demographic variables and cultural aspects that shape the volunteer profile. This work aims to analyze the differential and inter-related impact of socio-demographic and contextual variables, and cultural values on elder volunteer profile in Europe. We thus conduct an empirical study involving the use of a logistic regression model that shows, in probabilistic terms, traits that characterize senior and retired volunteers. Further, we study which variables motivate senior volunteers to a determined type of volunteering. Results from the European Value Study help to explain variable influence on volunteering and confirm that cultural values impact among elder people, both, election to volunteering activities and decisions regarding which kind of activity volunteers are drawn to. By analyzing two types of volunteering (religious and secular) that are supposed to be motivated by different forces, we conclude that certain values encourage religious volunteering while others stimulate secular volunteering.
Iranian EFL Teachers' Emotional Intelligence and their Use of Speaking Strategies
Authors: Shabani Karim
Published: June 2018

The study was designed to investigate the differences among Iranian EFL teachers in terms of emotional intelligence (EI) and their use of speaking strategies. To this end, 90 EFL male and female teachers teaching English at 9 institutes in Behshahr, Sari, and Amol cities in Mazandaran Province (north of Iran) were randomly selected. The research data were collected through the Bar-On EQ-I scale and teachers' use of speaking strategies questionnaire. Results on Independent Sample t-test reported significant differences in teachers' EI across gender. One-way ANOVA revealed differences in teachers' EI across years of teaching experience. Furthermore, results on Kruskal Wallis Test indicated differences in teachers' use of each speaking strategy regarding their level of EI.  Based on the findings, teachers with a higher level of EI preferred to focus on both accuracy and fluency and apply story-telling activities to create more successful interaction. While teachers with a lower level of EI preferred to focus on accuracy, they liked to apply information-gap activities. They preferred to offer implicit feedback through reformulation and tended to design groups and pairs to make silent students interact in the classroom. Moreover, both groups preferred to correct their learners later.
How are the Children of Immigrants Assimilating? The Effects of Individual, Neighborhood, Coethnic Community, and National Origin Group Characteristics on Education in San Diego
Authors: Lee Rennie
Published: June 2018

How immigrants’ children will integrate to US society is of ongoing debate. This study examines which assimilation pathway immigrants’ children are following. This study examines how four factors—individual, neighborhood, coethnic community, and national origin group—affect the children of immigrants’ educational attainment. I analyze a unique data set that matches individual survey data from the Children of Immigrants’ Longitudinal Survey (CILS) dataset with coethnic community, neighborhood, and group level data. The results indicate that coethnic community, group, and individual factors simultaneously influence the children of immigrants’ education, showing evidence for the selective assimilation pathway.
Collaborative Writing as Educational Research: a Deleuzian Critique
Authors: Harris David Ernest
Published: June 2018

This article discusses the claims made by some qualitative researchers that collaborative autoethnographic writing serves to displace sociology and other social sciences as a means to understand subjectivity.  Collaborative creative writing claims to be no less valid than sociological inquiry and is less socially exclusive, and academic criticism of this approach is itself seen as only subjective. A particular project by Wyatt and Gale and others can still be exposed to ‘immanent critique’, however, where the philosophical resources used to support the argument (the work of Deleuze and Guattari in this case) can be explored to suggest quite different implications for subjectivity. These include discussing external social influences on creativity and collaboration, and, more generally, on subjectivity itself. Guattari’s cartography of subjectification suggests that sociological inquiry, including the sociology of education, still has a major role in providing empirical examples and experiences of the processes involved, as resources for subsequent deleuzian philosophising and for effective micropolitics.
Shadow education and social class inequalities in secondary education in Greece: the case of teaching English as a foreign language
Authors: Tsiplakides Iakovos
Published: June 2018

This article deals with the shadow education system of private tutoring which contributes to the reproduction of social class inequalities, focusing on the Greek public secondary education system. It presents a literature review of the issue and the findings of an empirical qualitative and quantitative research that aimed at examining the causes of the students’ massive resort to private supplementary tutoring for learning the English language, despite the fact that English is taught at school. The study also set out to examine the relationship between students’ socioeconomic background and resort to private supplementary tutoring and the relationship between socioeconomic background and knowledge of the English language as attested by official certifications. Research findings indicate that the widely spread resort to private supplementary tutoring has a negative impact on the teaching of English in Greek public lower secondary education. Using Bourdieu’s cultural reproduction theory, we argue that private supplementary tutoring makes closer the relationship between social class, familial cultural and economic capital and educational outcomes. Thus, upper and middle class students are at an advantage, since they can move to the labour market with valued educational qualifications that enhance their occupational prospects. Finally, we discuss educational measures to address the problem.
Can Patients with Appendicitis in Pregnancy be Operated in Secondary Hospital: A retrospective Study
Authors: Budak Adnan , Şenlikçi Abdullah , Güven Ramazan
Published: June 2018

Appendicitis is the most common non-obstetric
cause of acute abdomen in pregnancy. Diagnosis of appendicitis becomes difficult with the
change of appendiceal position during pregnancy. Late diagnosis and treatment
increase the likelihood of developing perforation. In this study, we aimed to evaluate perioperative outcomes of
appendicitis in pregnant patients in secondary hospitals in the light of the
literature. 29 pregnant
women who performed appendectomy between April 2012 and July 2017 were included
in the study. Patients were evaluated according to age, gestational age, white
blood cell count, percentage of neutrophil count, C-reactive protein level,
ultrasonographic findings, pathologic results, duration of hospitalization and
complications. Out of the 29 pregnant patients, 9 (31.0%) patients had surgery during the first trimester, 13
(44.8%) during the second trimester and 7 (24.2%) during the third trimester. Median
white blood cell count was 12870 K/mm3 (min-max;7170-25210).
Negative laparotomy rate was %31.0. Median duration of hospitalization was 3.24
days (2-7). Morbidity was observed in 2 (6.9%) of 29 patients. Intra-abdominal
abscess was observed in one patient and colonic fistula was observed in one
patient. Our results demonstrated that
appendectomy and follow-up of pregnant patients with acute appendicitis can be performed at secondary
hospitals.

Levels and effects of natural radionuclides in sediment banks of Rhumel River (Northeast Algeria)
Authors: Bouhıla Ghania , Benrachı Fatima , Ramdhane Mourad
Published: June 2018

Activity
concentrations of natural radionuclides in Boumerzoug River sediment (the main
tributary of Rhumel river) have been measured using high resolution HPGe
detector. The activity concentrations of the samples were range from 16.66±2.32 Bq/kg to 43.48±4.03 Bq/kg with mean value of 26.64±1.33 Bq/kg for 226Ra, 20.01±1.98 Bq/kg to 32.71±3.85 Bq/kg with the mean value 25.95±1.46 Bq/kg for 232Th and 81.70±33.59 Bq/kg to 259.20±38.80 Bq/kg with the mean value
164.50±11.30 Bq/kg for 40K. These values were used to
estimate the radiation hazard indices. The absorbed dose and annual effective
dose were evaluated to assess the radiation risk due to the use of these
sediments.
Thickness Dependent Dielectric Loss of Plasma Poly (Ethylene Oxide) Films
Authors: Ulutaş Hulusi Kemal
Published: June 2018

Dielectric properties of plasma poly (ethylene
oxide) (pPEO) thin film samples were investigated at room temperature. The thin
film samples with different thicknesses were deposited by plasma assisted
physical vapor deposition (PAPVD) technique at 5 W plasma discharge power. The
thicknesses were 20, 100, 250, 500 nm. It was observed that dielectric constant
increases with increasing thickness. The relaxation times determined by
dielectric loss-frequency relation, shift toward higher frequencies with
increasing thickness. In addition film thickness, heating processes were
defined as another parameter. By this purpose, thin film samples were heated
and cooled, respectively. It was observed that maxima and minima of dielectric
loss at cooling process take place at lower frequencies in comparison with
frequencies at which maxima and minima were detected at heating process. These
results may show the effect of dead layer at thinner films. After heating
process, it was observed from behavior of dielectric constant and dielectric
loss that the crosslinking density increases by heating effect. This effect may
cause additional reactions between free radicals which are production of PAPVD.
Moreover, dynamic glass transition temperatures were calculated. These
temperatures prove the effect of dead layer approximation.

Authors: Zaldívar Allona Natalia , Pérez de Albéniz Iturriaga Alicia , Fonseca Pedrero Eduardo
Published: June 2018

Los trastornos mentales son un problema de salud global, no obstante, en La Rioja, se han llevado a cabo pocos estudios empíricos que traten de analizar los problemas emocionales y comportamentales en población infanto-juvenil. El objetivo principal fue conocer el estado de salud mental en los niños y adolescentes riojanos de 4 a 14 años, así como su relación con distintos indicadores de salud física y hábitos de vida saludables. La muestra la conformaron un total de 101 participantes (M= 9,44; DT=3,12; 57 hombres; 44 mujeres), extraídos de la Encuesta Nacional de Salud de España 2011/12. Se utilizaron el Strengths and Difficulties Questionnaire versión heteroinforme y el KIDSCREEN-10, para evaluar la salud mental y la calidad de vida relacionada con la salud, respectivamente. También se emplearon preguntas sobre hábitos de vida saludable (comida, actividad física, sueño) y trastornos mentales previos diagnosticados. Los resultados indicaron que el 5% de la muestra riojana presentó riesgo de mala salud mental y el 8,9% obtuvo puntuaciones límites. La subescala problemas emocionales del SDQ se asoció de forma negativa con las puntuaciones del KIDSCREEN-10. Los participantes considerados “de riesgo” no refirieron una peor calidad de vida ni una mayor prevalencia de trastornos mentales en comparación con el grupo de “no riesgo”. No se encontró relación entre riesgo de mala salud mental y los hábitos de alimentación (a excepción del consumo de comida rápida), la actividad física o el descanso. Estos hallazgos permiten tener una visión actual sobre el estado de salud mental de los jóvenes riojanos de cara a destinar recursos e implementar programas de promoción del bienestar emocional.
NUMERICAL INVESTIGATION OF FORCED CONVECTION OF NANOFLUID IN MICROCHANNELS HEAT SINKS
Authors: BELHADJ A.
Published: June 2018

This paper presents a numerical
study of laminar forced convective flow of nanofluid-based water/Al2O3
in a two-dimensional horizontal microchannel heat sink. The governing
equations are solved by using the finite volume method based on simple
algorithm. The effect of solid nanoparticles on the heat transfer is
investigated after comparing our results with experimental data. The founding
results showed that the use of nanofluid has enhanced the heat transfer in
comparison with pure fluid, and the increasing of Al2O3
concentration enhances the thermal and dynamic parameters. Nusselt number and
friction coefficient have been enhanced with the increasing of Reynolds number.
This work contributes to ameliorate the cooling systems by integrating the
nanofluids in the next generation of microchannels heat sinks.
THERMAL PERFORMANCE ANALYSIS OF CONVECTIVE-RADIATIVE FIN WITH TEMPERATURE-DEPENDENT THERMAL CONDUCTIVITY IN THE PRESENCE OF UNIFORM MAGNETIC FIELD USING PARTIAL NOETHER METHOD
Authors: SOBAMOWO M. G.
Published: June 2018

In this paper, thermal
performance of convective-radiative straight fin with temperature-dependent
thermal conductivity in the presence of uniform magnetic field is analyzed
using partial Noether method. The exact analytical solution is used to
investigate the effects of magnetic field, convective, radiative,
thermo-geometric and thermal conductivity (non-linear) parameters on the
thermal performance of the fin.
The results reveal that as the magnetic, convective
and radiative parameters increase, the temperature of the fin decreases rapidly
and by implication, the rate of heat transfer through the fin increases.
The study provides a platform for comparison of results of any other method of
analysis of the problem with the results of the exact analytical solutions in
this paper. Also, such an analytical tool is valuable as a design and
optimization approach for large scale (not necessarily in size) finned heat
exchangers where each fin/row are analytically analyzed and where the
surrounding fluid is influenced by a magnetic field.
Molinos harineros en Chile (1700-1845): implicancias sociales y culturales
Authors: Lacoste Pablo
Published: June 2018

El Reino de Chile fue el principal productor de trigo de América del Sur en el periodo colonial, y generó una de las mayores redes de molinos harineros de la región, integrada por cientos de pequeños y medianos establecimientos. Este artículo describe y explica estos molinos con sus implicancias sociales y culturales, a partir de documentos originales inéditos del Archivo Nacional Histórico de Santiago de Chile. Se detecta que estos molinos promovieron el desarrollo de oficios especializados (molineros, albañiles, carpinteros y tejeros) y, al igual que las economías viñateras, promovieron la movilidad social ascendente a través del país. Además, los molinos funcionaron como focos de sociabilidad donde se fortalecían los lazos entre distintos sujetos dando mayor densidad a la vida campesina, y operaron como referentes de los paisajes rurales, formando parte de complejos diversificados integrados con viñas, bodegas, huertos frutales y majadas de ovejas y cabras.
Therapeutic Doses of Eltrombopag do not Inhibit Hepatic BCRP in Healthy Volunteers: Intravenous Ceftriaxone as a Model
Authors: Neves Daniel Valente , Vieira Carolina Pinto , Rocha Adriana , Lanchote Vera Lucia
Published: June 2018

PURPOSE: Ceftriaxone elimination occurs through breast cancer resistance transporter (BCRP) and multidrug resistance-associated protein 2 (MRP-2) which are expressed on the canalicular membrane of hepatocytes. Eltrombopag, a thrombopoetin receptor agonist used in the treatment of immune thrombocytopenic purpura, is reported in in vitro studies as an inhibitor of intestinal BCRP but not an inhibitor of hepatic BCRP. Thus, the present study evaluates the effect of therapeutic doses of eltrombopag on the clinical pharmacokinetics of intravenous ceftriaxone. METHODS: Healthy adult (n=12) were treated with oral doses of eltrombopag (0, 25 or 50 mg) 28 and 4 h prior to intravenous ceftriaxone administration (1g). Serial blood samples were collected up to 48 h after ceftriaxone administration and plasma samples were analysed by LC-MS/MS using 50 μL aliquots (total concentration) and 100 μL (unbound concentration). RESULTS: A method to analyze total and unbound ceftriaxone in plasma using LC-MS/MS was developed and validated with linearity from 1 to 200 μg/mL. Both methods are sensitive, precise and accurate with coefficients of variation less than 15% in the study of inter- and intra-assay precision and accuracy. Ceftriaxone pharmacokinetics in healthy adults were described using a bicompartmental model, with a mean clearance of 0.96 L/h (CI95% 0.71-1.20) and AUC0-∞of 1106 mg.h/mL (CI95% 811-1400) for volunteers that received only ceftriaxone; clearance of 0.95 L/h (CI95% 0.77-1.13) and AUC0-∞ of 1083 mg.h/mL (CI95% 876-1290) for volunteers that received ceftriaxone plus 25 mg of eltrombopag and clearance of 0.96 L/h (CI95% 0.74-1.19) and AUC0-∞ of 1072 mg.h/mL (CI95% 872-1273) for volunteers that received ceftriaxone plus 50 mg of eltrombopag. CONCLUSIONS: The results do not support the existence of a clinical pharmacokinetic drug interaction involving hepatic BCRP in human subjects receiving intravenous ceftriaxone and oral eltrombopag. This article is open to POST-PUBLICATION REVIEW.

Published: June 2018

Nonlinear oscillations of a mass with serial linear and nonlinear
stiffness on a frictionless surface is considered. Equation of motion of the considered system is obtained. For analysing of the
system, relatively new perturbation method that is named Multiple Scales
Lindstedt Poincare (MSLP) and classical multiple scales (MS) methods are used.
Both approximate solutions are compared with the numerical solutions for weakly
and strongly nonlinear systems. For weakly nonlinear systems, both approximate
solutions are in excellent agreement with numerical simulations. However, for
strong nonlinearities, MS method is not give reliable results while MSLP method
can provide acceptable solutions with numerical solutions.
Effect of Dopant Structure on Birefringences and Symmetric Tensor Invariants of Lyotropic Nematic Phases
Authors: Akpınar Erol
Published: June 2018

In this study,
we investigated the effect of the dopant structure on the birefringences and
the symmetric tensor invariants of lyotropic discotic nematic (ND),
calamitic nematic (NC) and biaxial nematic (NB) phases.
Lyotropic host mixture consisted of potassium laurate (KL)/decanol
(DeOH)/water. Some dopant molecules were added to this host mixture to obtain
quaternary mixtures and to investigate the nematic phase properties by
polarizing optical microscopy and laser conoscopy. It was found that the dopant
molecules with aromatic ring affect the birefringences and symmetric tensor
invariants more efficiently than those with straight alkyl chain.
Investigation of Diffuse Hair Fall Case Due to Vitamin D Deficiency: A Case Report and Literature Review
Authors: Suad H. H. , Modawe Gad Allah
Published: June 2018

A 45-year-old female from northern Sudan presented a complaint of diffuse hair loss from her scalp for 4 years. The condition started when she was in Saudi Arabia, where she resided for five years with her husband and children. The condition is associated with fatigability and easily falling asleep. The condition is static with no known relieving or aggravating factors. She looks well, not pale, jaundiced or cyanosed, regular pulse, no lymph node enlargement; thyroid is central with normal size and no lower limb edema. Scalp: looks normal, no scales or erosions. Hair: hair is dry with normal texture; loss is diffuse, no apparent patch of alopecia. Axillary and pubic hair is normal. All investigations were within normal values except serum vitamin D that was found to be very low: 9 (average value 30–300). Management plans to correct the deficiency for three months, and then a daily maintenance dose is to be prescribed. The monitoring of vitamin D serum level is to be assessed to avoid hyper vitaminosis. Vitamin D supplement was prescribed as oral tabs of 50,000 IU weekly for three months. Daily maintenance dose of 1000 IU was prescribed. Improvement was noticed starting from the first month, and excellent result was achieved after three months of daily supplementation; daily maintenance dose was then prescribed with an advice of being outdoors to enhance endogenous synthesis. Conclusion: Serum vitamin D level should be assessed in patients with hair loss, especially those at a risk because of being indoors.

Authors: Ahmed Sharfi , Elseed Khalid Awad
Published: June 2018

Fungal rhinosinusitis (FS) is considered as a disease spectrum that ranges from allergic fungal sinusitis (AFS) and chronic fungal rhinosinusitis (CFS) to invasive fungal rhinosinusitis (IFS) invading the orbit, Dura, and intra-cranium. Fungal rhinosinusitis is a common disease in Sudan.
Objective: To present four rare cases of InvasiveFungal Rhinosinusitis in Sudanese children presented with orbital extension.
Patients and Method: The authors have reported four cases of children in the age range of 9–11 years, two girls and two boys; they were presented with invasive fungal rhinosinusitis in Africa ENT hospital (Sudan) during the period from September 2015 to August 2017. Patients’ diagnosis was made by endoscopic examination, CT, and MRI,and it was confirmed by tissue biopsy.
Results: Patients’ age range was 9–11 years, two girls and two boys. The unilateral disease was the commonest type. An orbital extension was detected in all cases on CT and MRI. No intracranial extension was detected. Aspergillus flavus was the most responsible agent detected in all the fourcases.
Conclusion: Fungal rhinosinusitis (FS) is a common disease in adult Sudanese patients but rarely affects children. It is mainly caused by Aspergillus species. The disease is extensive and can be associated with orbital and intracranial complications.

Published: June 2018

As águas residuárias são normalmente um empecilho ambiental para o desenvolvimento da indústria têxtil em razão do gerenciamento inadequado e/ou tratamento ineficaz, que levam à contaminação da biota. Efluentes de indústrias têxteis têm como uma de suas principais características a alta carga de corantes, os quais durante o processo produtivo não se aderiram à fibra e, assim, encontram-se presentes no efluente final. Estes, quando lançados no ambiente aquático, reduzem a disponibilidade de luz e a realização da fotossíntese e ocasionam outros problemas ambientais. Além disso, a maioria dos corantes têxteis são tóxicos, mesmo em pequenas concentrações. Enzimas produzidas por Pleurotus sajor-caju são reportadas como eficientes na remoção de cor, degradação de corantes e detoxificação de efluentes têxteis. Assim, neste trabalho teve-se como objetivo avaliar a capacidade do caldo enzimático bruto de Pleurotus sajor-caju em remover a cor e, concomitantemente, diminuir a toxicidade de soluções que contêm os corantes têxteis Red 50 e Blue 56 (100 mg L-1). Para tal, produziu-se o caldo enzimático em biorreator (volume útil de 4 L), que foi adicionado diretamente sobre a solução de corantes sem diluição, diluído em água (1:1) e diluído em solução ABTS (2,2’-azino-bis(3-etilbenzotiazolina-6-sulfônico)) (1:1). O microcrustáceo Daphnia magna foi utilizado nos testes ecotoxicológicos. Observou-se maior eficiência na remoção de cor pelo caldo enzimático bruto de P. sajor-caju diluído em solução ABTS (taxas de remoção 1,3 e 1,9x10-2 mg U-1 h-1, para os corantes Red 50 e Blue 56, respectivamente). A enzima lacase foi quantificada no caldo enzimático (115 U L-1) e manteve 100% de sua atividade durante todos os experimentos. Observou-se redução estatisticamente significativa da toxicidade para o corante Blue 56. O corante Red 50 manteve-se tóxico mesmo após o tratamento enzimático, sugerindo a necessidade de maior tempo de reação para esse corante. O caldo enzimático bruto de P. sajor-caju mostrou-se eficaz e de uso promissor em estações de tratamento de efluentes têxteis.Palavras-chave: Basidiomicetos. Caldo enzimático. Ecotoxicidade.
Efeito do exercício físico intenso nas concentrações sérica, salivar e urinária de marcadores de lesão músculo esquelética
Authors: Chielle Eduardo Ottobelli , Maziero Jorlana Stake
Published: June 2018

A lesão muscular esquelética é um evento frequente entre os atletas. O diagnóstico utilizando os marcadores sanguíneos clássicos às vezes produz resultados insatisfatórios em razão da grande variabilidade interindividual. Portanto, a identificação de biomarcadores confiáveis e agudos é importante. Neste estudo verificou-se a atividade sérica, salivar e urinária de marcadores bioquímicos indicadores de lesão musculoesquelética em resposta ao dano muscular agudo induzido por exercício físico intenso. Realizou-se um estudo transversal com 27 jogadores de futebol americano com idade média de 22,5 anos. Os atletas foram submetidos a um questionário antes da realização da atividade física e em seguida realizou-se a avalição de parâmetros clínicos. Antes dos exercícios físicos intensos (T0), 60 minutos (T1) e 24 horas (T2) após o treinamento foram coletadas por punção venosa amostras de sangue que foram acondicionadas em tubos com anticoagulante (heparina) e sem anticoagulante, e posteriormente foi determinada a atividade das enzimas Creatina Quinase (CPK), Adenosina deaminase (ADA), aldolase, Lactato desidrogenase (LDH), Transaminase Glutâmica Oxalacêtica (TGO) e Transaminase Glutâmica Pirúvica (TGP) em amostras de soro, saliva e urina, além da concentração das Substâncias Reativas ao Ácido Tiobarbitúrico (TBARS). Observou-se um aumento significativo da atividade da aldolase, ADA e CPK no soro, da aldolase na saliva e ADA, CPK, TGO e TGP na urina. Também houve um aumento sugnificativo do TBARS salivar e urinário após exercício físico intenso. Em conjunto, os resultados mostraram que a atividade da ADA sérica e urinária, TBARS urinário e salivar, aldolase salivar e TGO e TGP urinário (p<0.01) poderiam ser biomarcadores eficazes e promissores de lesão muscular aguda, permitindo uma avaliação rápida de lesões induzidas pelo exercício físico intenso e fadiga muscular, contribuindo para o monitoramento de atletas e dessa forma, para evitar lesões mais graves e afastamento dos atletas.Palavras-chave: Lesão muscular.

Eutanásia canina como medida profilática para o controle da leishmaniose humana: uma abordagem bioética
Authors: Souza Gilberto de , Lima Guilherme Henrique Monteiro Alves de
Published: June 2018

A leishmaniose é caracterizada como um complexo de doenças parasitárias e constitui um grande problema de saúde pública, ficando entre as seis principais doenças tropicais nos países em desenvolvimento, de acordo com a Organização Mundial de Saúde (OMS). O cão é considerado o mais importante reservatório de infecção urbana, podendo apresentar infecção assintomática, com alto grau de parasitismo cutâneo, continuando a transmitir a doença. Nesse contexto, ações de controle rígidas, em especial por meio da eutanásia de cães soropositivos, são necessárias. Outros métodos de controle incluem a utilização de inseticida residual, a gestão ambiental em residências e uma rigorosa vigilância epidemiológica. A eutanásia foi inicialmente conceituada como o ato de tirar a vida, podendo ser aplicada para humanos e animais. Hoje ela pode ser entendida como uma prática utilizada para abreviar a vida, com o intuito de aliviar ou evitar o sofrimento. No Brasil, a Portaria Interministerial n. 1.426, de 2008, proibe o tratamento dos cães infectados ou doentes, e a Resolução n. 714, de 2002, do CFMV, dispõe sobre os procedimentos para a realização da eutanásia. Nesse contexto, pensando especificamente na eutanásia canina como medida profilática para a leishmaniose humana, uma discussão bioética deve ser amplamente estimulada, uma vez que existem outras condutas que podem ser adotadas como medidas de prevenção, podendo-se citar o tratamento dos pacientes humanos e o controle dos vetores no ambiente. Vários estudos também devem desenvolvidos com a ajuda da biotecnologia, com estimulação de imunoterapias e terapias vacinais para o controle da leishmaniose.Palavras-chave: Bioética. Leishmaniose.

El ordenamiento del territorio urbano y rural, imperativo para garantizar igualdad en los territorios
Authors: Camargo Carvajal Jorge Eduardo , Lizcano Noguera Andrea
Published: June 2018

La población campesina en Colombia enfrenta una alta desigualdad en materia de acceso y garantía de los derechos, situación que se debe en parte a que no se ha realizado la reforma agraria. El Gobierno nacional, en el marco del Acuerdo de Paz con la FARC, pactó como una de las bases para la consolidación de la paz la necesidad de hacer una reforma rural integral, por lo que parte del éxito de la implementación de cada uno de los acuerdos está en la ordenación del territorio rural y la participación en este de los campesinos.
Innovación social como motor del desarrollo local y el emprendimiento social
Authors: Tortosa Conchillo Juan Miguel , De Pablo Valenciano Jaime , Uribe Toril Juan
Published: June 2018

En este artículo se aborda la innovación social en el desarrollo local y el emprendimiento social desde una perspectiva teórico-práctica, tomando como referencia los nuevos yacimientos de empleo (NYE). Para ello, se parte de la sistematización de experiencias en tres municipios de la provincia de Almería, España, centradas en la mejora de vida de las personas (servicios a domicilio, cuidado de niños y ayuda a jóvenes con dificultades de inserción). La implementación de estos centros ha repercutido positivamente en los municipios rurales en su lucha contra el envejecimiento y despoblamiento, y se ha logrado mantener e incluso incrementar la producción, la renta y el empleo.
Plan de Desarrollo Municipal de Candelaria: análisis factorial de las brechas sociales y revisión del concepto de desarrollo a través del análisis crítico del discurso
Authors: Vasquez Salazar Lina Maria , Mejia-Caceres Maria Angelica , García Gonzalez Juan David
Published: June 2018

Desde el presupuesto de que los documentos políticos expresan explícita e implícitamente relaciones de poder, ideologías y la posibilidad de mantener o transformar las injusticias sociales, el Plan de Desarrollo Local de Candelaria (PDLC) puede considerarse como un proyecto cargado de intereses materializados a través de su discurso político. Para comprender el contexto social de Candelaria, en el artículo se realiza un análisis de componentes principales del índice de pobreza multidimensional de los municipios del Valle del Cauca, con miras a identificar los elementos que debería abordar el PDLC. Posteriormente, se realizó una revisión de este plan a través del análisis textual y el análisis de la práctica discursiva, con base en los criterios construidos por Mejía-Cáceres, Martins y Freire (2017). Luego se identificó la estructura textual, cohesión y repetición de la palabra desarrollo, además de estudiar su sentido. Los resultados muestran que este término implica un sentido de relación o entretejimiento, así como una operacionalización de ideología de estandarización y de unidad, a fin de construir una identidad colectiva de la comunidad de Candelaria.
Institutionalisation of Women's Studies Research Centre, Gauhati University: A Struggle for Space and Identity
Authors: Dutta Dipmala , Vauquline Polly
Published: June 2018

Institutionalisation of Women's Studies (WS) in India although started in the 1970s, it took a decade further to cross the threshold of Northeastern States. The  isolation  which the Northeast of India has always faced in the social, economic and political spheres was also reflected  in the case of establishment of the Women's Studies Centres as the then Vice Chancellor Dr. Deba Prasad Barooah had to struggle against the University Grants Commission for establishing it in Gauhati University. Again, the narrative of WSRC, GU do not find mention in the book Narratives from Women's Studies Family: Recreating Knowledge where experiences of 17 centres from across the country are illustrated. This paper investigates all such structural difficulties, negligence and struggle faced by one of the first Women's Studies Centre of Northeast India, established in Gauhati University (GU), since its conceptualisation to inception in 1989 till the present. It attempts in revealing the experiences of the Directors, yielding the efforts behind the setting up of the centre, the role played by different individuals both internal and external of the University towards the establishment of the Centre, the catalysts that prevented the premature decay of the Centre and most importantly the struggle for space, identity and recognition the constraints faced to obtain them. To achieve these goals oral history method was applied to explore the experiences of the previous directors and the author (2nd author) herself. The narratives illustrate the history of struggles, challenges and the subsequent development over a span of more than twenty five years. The paper documents the support the University provided despite being a patriarchal institution for fostering of the WSRC, which in gradual years took steps to produce the Department of Women's Studies. It will also look into the progressive role Women's Studies played not only in the varsity internally but also at the external front through research and advocacy by inducing new panoramic view towards and discussion of women's issues in a multidimensional framework.
Socio-cultural dominants of the library partnership: the experience of analyzing the database «Librarianship and bibliography»
Authors: Babich I. V.
Published: June 2018

The article deals with socio-cultural dominants of the library partnerships. The interpretation is based on the quantitative and content analysis of database records «Librarianship and bibliography», which supported currently by the Center for Studying Problems of Libraries Development in the Information Society of the Russian State Library. 266 items were selected based on searching the words «partnership», «cooperation» and all their derived forms in the records relating to Russia taking into account their fixation in headings and abstract texts. The author attempts to trace the dynamics of reflecting the libraries partnership experience in publications (monographs, articles in professional press, conference proceedings, manuals and textbooks) for 2010-2015 taking into account the status of partnerships (international, regional, urban, rural ones), related strategic objectives, tactical means of achieving them, the importance of choosing a particular partner in terms of the final result of cooperation, the partnership place. The ration of activities to promote reading and cultural activities in modern Russian libraries considers in the partnership frames. The author came to the following conclusions: the chronological distribution of the data detects the trend of growing attention to the topic of partnerships in 2010-2015; in spite of the diversity of the concrete wordings, main targets are: cultural, promote reading, enhance the role of libraries in society, the positioning of «own» territory (region, city, district, etc.). Their employees think that the key to the libraries relevance are less associated with the reading process. In searching the means to adapt libraries to the information society conditions, which are guides in the information world, library professionals are increasingly turning to the popularization of domestic tourism, the creation of the mental orientation system relevant to the local population, participation in local cultural events. «Small motherland» is perceived as the most important marker of identity, and the libraries partnership with other cultural institutions and public associations as an effective demonstration of the libraries’ capabilities in the society cultural mobilization.
