Effects of extrusion parameters on tensile strength of polybenzimidazole fiber-reinforced high density polyethylene composites
Authors: Anis Arfat , Faiz Shan , Al-Zahrani Saeed M.
Published: June 2015

The objectives of this study were to examine the effects of fiber content and extrusion parameters on polybenzimidazole (PBI) fiber-reinforced polyethylene composites and to determine the optimum values for the tensile strength. The PBI fiber was physically mixed with high density polyethylene (HDPE) and then extruded through a twin screw extruder. The extrusion parameters were studied at different levels, barrel temperatures at 240°C, 250°C and 260°C and screw speeds at 12 rpm, 15 rpm and 18 rpm. The tensile strength was measured using a universal testing machine. A response surface experimental design using Design-Expert was applied to investigate the effect of fiber loading and extrusion parameters (barrel temperature, screw speed) on tensile properties of the resulting composite and consequently analyzing the optimized value for these parameters to yield maximum tensile strength. The analysis predicted a linear model which suggests that in order to achieve maximum tensile strength the screw speed should be 18 rpm, the barrel temperature at 240°C and at a fiber loading of 2%.

Epistemic marking and multiple perspective: An introduction
Authors: Bergqvist Henrik
Published: June 2015

This paper discusses forms of epistemic marking that instantiate multiple perspective constructions (see Evans 2005). Such forms express the speaker’s and the addressee’s simultaneous epistemic perspectives from the point of view of the speaker, crucially relying on the assumptions of the speaker with regard to the addressee’s knowledge. The analysis of forms considers established semanto-pragmatic concepts, such as semantic scope, mitigation strategies and communicative intention (as marked by sentence-type) in the exploration of forms. In addition, the notion of knowledge asymmetry is discussed alongside the concepts of epistemic status and stance as tools for a semantic analysis of investigated forms.
Refracting views: How to construct complex perspective in reported speech and thought in Ungarinyin
Authors: Spronck Stef
Published: June 2015

This paper analyses reported speech, thought and epistemic modality in the North Western Australian Aboriginal language Ungarinyin. It demonstrates how these grammatical domains interact in the language to encode multiple perspective meanings. The paper concludes by discussing some implications of the Ungarinyin patterns for expressions of complex perspective elsewhere.
A Meshless Method Based on Radial Basis and Spline Interpolation for 2-D and 3-D Inhomogeneous Biharmonic BVPs
Authors: Shivanian Elyas
Published: June 2015

This paper presents a meshless method which, at the first step, utilises the radial basis functions collocation scheme to approximate the unknown function at specific nodal points. The difficulty of these biharmonic-type problems is the multiple boundary conditions, as well as high derivatives terms. The inhomogeneous biharmonic equation is replaced by two Poisson equations of an intermediate function where Neumann’s boundary conditions is of second derivatives. It uses the imposed-kernel technique (IKT) to overcome multiple boundary conditions where Neumann’s boundary conditions is of first derivatives. In the next step, our meshless approach uses two- and three-dimensional cubic spline interpolation to get smooth, approximate solutions for the 2-D and 3-D inhomogeneous biharmonic-type problem, respectively. Numerical experiments are included to demonstrate the reliability and efficiency of this method.

Published: June 2015

El objetivo del presente estudio fue explorar el grado de diversidad genética inter-regional presente en el ganado bovino de Costa Rica. Se colectaron 1498 muestras de ADN (año 2013) procedentes de ocho diferentes regiones del país. Se calcularon las frecuencias alélicas y los principales parámetros genéticos poblacionales para dieciocho marcadores microsatélite. Se realizó además un análisis de varianza molecular y se calcularon las distancias genéticas entre bovinos de diferentes regiones. A nivel nacional se observó un alto grado de diversidad, con un número promedio de 14,6±1,01 alelos observados y 5,6+0,37 alelos efectivos por marcador. La heterocigosis observada (Ho) fue 0,76±0,01 y la esperada (He) 0,81±0,01. El contenido de información polimórfica (CIP) fue de 0,79±0,06 y el índice de consanguinidad (FIS) fue de 0,06±0,004. A nivel de regiones, la Ho varió desde 0,73±0,02 en la región Central Sur hasta 0,78±0,01 en la región Huetar Norte. El dendrograma mostró tres agrupaciones claramente diferenciadas, con las regiones Central Metropolitana y Central Occidental en un grupo; Huetar Caribe, Central Sur, Pacífico Central y Chorotega en un segundo grupo; y Huetar Norte y Brunca en un tercer grupo intermedio. Los estimados de diferenciación genética RST fueron significativos entre regiones de distintos grupos y no significativos entre regiones de un mismo grupo. Las diferencias genéticas entre regiones se relacionaron con la proliferación diferenciada de tipos raciales en función de su adaptabilidad a las condiciones agroecológicas y a los sistemas de producción imperantes en cada región.

El objetivo de este estudio fue evaluar el efecto de la zeolita sobre la eficiencia de uso de fertilizantes nitrogenados en el cultivo de arroz. El experimento se estableció en El Cacao, Tonosí, provincia de Los Santos, Panamá, entre agosto y diciembre de 2012 y 2013, bajo condiciones de secano. Se utilizó la variedad de arroz IDIAP FL 106-11 con densidad de siembra de 110 kg/ha en un Fluvisol vértico de fertilidad media. El estudio consistió de cinco tratamientos con cuatro repeticiones, un diseño de bloques completamente aleatorizados, y una dosis de N de 80 kg/ha, mezclado con diferentes porcentajes de zeolita (0; 15; 25; 35 y 45%). Se empleó la técnica isotópica de 15N 3% en exceso, para determinar eficiencia de uso del fertilizante nitrogenado (EUFN). Cada unidad experimental consistió de 15 m2 con tres micro-parcelas de 1 m2 en donde se aplicó la urea marcada con 15N en diferentes épocas del ciclo del cultivo para determinar EUFN en cada aplicación. Los mejores rendimientos de grano se obtuvieron con 80 kg N + 45% zeolita/ha y 80 kg N +15% zeolita/ha. Se logró un incremento en la EUFN de un 7% con la adición de zeolita natural. Pequeñas dosis de 12 kg/ha (15%) de zeolita puede mejorar la EUFN permitiendo mediante sucesivos experimentos, recomendar una disminución en la cantidad de N a aplicar en suelos con condiciones edafoclimáticas similares, aptos para el cultivo de arroz.

Objetivo. La cirugía transnasal hernia transesfenoidal endoscópica es la base del tratamiento para la acromegalia en nuestro centro. Realizamos un estudio retrospectivo de 2008-2011 para determinar si este abordaje induce remisión bioquímica, y comparamos nuestras observaciones con series publicadas. Métodos. Analizamos retrospectivamente nuestra base de datos, e identificamos los pacientes sometidos a cirugía transnasal transesfenoidal endoscópica como tratamiento primario de acromegalia. Valoramos las imágenes y perfiles endocrinológicos pre-operatorios, y utilizamos los criterios del Consenso de Acromegalia de 2009 para determinar la remisión bioquímica. Resultados. Ocho pacientes recibieron adenomectomía endoscópica primaria. Uno tenía un microadenoma, uno un macroadenoma no invasivo, y seis presentan macroadenomas invasivos. La media de los niveles del factor de crecimiento similar a la insulina tipo I tres meses post-cirugía fueron 633 ng/mL (199 ng/ml-1600 ng/mL), mientras que los de la hormona de crecimiento fueron 10,20ng/mL (0,96ng/mL-16,60ng/mL). Dos pacientes cumplieron criterios de remisión; un macroadenoma no invasivo y un microadenoma. Cuatro de los pacientes restantes tuvieron remisión con análogos de somatostatina. Conclusiones. Este es el primer reporte de cirugía transnasal transesfenoidal endoscópica como terapia primaria de acromegalia en Costa Rica. La cura en pacientes con macroadenomas grandes e invasivos puede ser difícil y requiere de terapia multimodal.

Published: June 2015

Objetivo. Conocer el proceso de Certificación Hospitalaria en México. Resultados. México contaba con estándares de calidad institucionales, pero no había una evaluación externa que determinará si éstos estaban o no cualificados, de igual manera influía la falta de una legislación estricta en materia de salud la cual se promulgó de una manera eficaz en el 2009, ésta obliga a todos los establecimientos de salud entrar en la era de la certificación. Con lo anterior, el número de hospitales certificados va en aumento y con ello la participación activa del Farmacéutico o Químico Farmacéutico Biólogo (QFB). Conclusión. La certificación Hospitalaria en México va en aumento, con el compromiso de homologar los servicios de salud a nivel internacional. La participación del Farmacéutico o QFB es indispensable, ya que en la mayoría de los establecimientos de salud aún no se cuenta con un profesional farmacéutico en las distintas áreas que se requiere, por lo que la certificación, es una gran oportunidad para la participación directa del Farmacéutico o QFB en el ámbito hospitalario, cumpliendo los estándares de calidad y metas internacionales en materia de salud.

La leche materna es el único alimento que le provee al lactante la cantidad y calidad exacta de nutrientes, que requiere para su desarrollo, como carbohidratos, grasas, proteínas e inclusive inmunidad y biomarcadores. Por lo tanto, es fundamental que tanto odontólogos, como el personal del área de salud, comprendan las generalidades de la lactancia, su importancia y la correcta farmacoterapia de la mujer en este periodo; debido a que se pueden utilizar analgésicos como el acetaminofén, diclofenaco e ibuprofeno, los cuales se consideran compatibles con la lactancia y de igual forma los antibióticos de uso frecuente en odontología como las penicilinas y las cefalosporinas. De tal manera que se le pueda ofrecer una atención adecuada y oportuna sin perjudicar la salud de la madre y su hijo.

Absztrakt

Elméleti háttér: A multifaktoriális etiológiai háttérrel rendelkező
evészavarok szociokulturális magyarázóelméletei nagy szerepet tulajdonítanak a
megjelenéssel kapcsolatos szociokulturális hatásoknak és a megjelenés
szociokulturálisan meghatározott standardjai internalizációjának.
Cél: A vizsgálat célja a Megjelenéssel Kapcsolatos
Szociokulturális Attitűdök Kérdőív (Sociocultural Attitudes Towards Appearance
Questionnaire-3 — SATAQ-3; Thompson és mtsai, 2004) magyar nyelvű változata
faktorstruktúrájának tesztelése és a megjelenéssel kapcsolatos szociokulturális
attitűdök egyes testképzavarokkal való kapcsolatának egy komplex modell
keretében történő felmérése volt. Módszerek: A keresztmetszeti,
kérdőíves kutatás résztvevői gimnazista lányok és főiskolai hallgatónők voltak
(n = 198, átlagéletkor: 18,7 év, szórás = 2,82 év). Mérőeszközök: önbeszámoló
útján nyert testtömeg és testmagasság, SATAQ-3, Evési Zavar Kérdőív.
Eredmények: A SATAQ-3 kérdőív konfirmatív faktoranalízise
nem zárult kielégítő eredménnyel (χ2(399) = 861,3, p < 0,001; CFI
= 0,831; TLI = 0,815; RMSEA = 0,077). Az exploratív faktoranalízis eredményei
szerint a négyfaktoros megoldás illeszkedése közelítette az elfogadhatót
(χ2(321) = 612,0, p < 0,001; CFI = 0,893; TLI = 0,856; RMSEA =
0,068). Az Információ és a Nyomás skálák tisztán megjelentek, az
Internalizáció—általános skála tételei egyazon faktoron töltődtek, azonban az
Internalizáció—kisportolt skála tételei jelentős kereszttöltődést mutattak ezen
a faktoron. A skálák belső megbízhatósága megfelelőnek bizonyult. Az életkor és
a testtömegindex kontrolljával végzett útelemzés eredményei szerint a média
felől érkező, a karcsú testideál elérésére irányuló észlelt nyomás a karcsú
testideál internalizációján keresztül testi elégedetlenséghez és karcsúság
iránti késztetéshez vezet. A médiából érkező információ szubjektív fontossága és
a karcsú testideál internalizálása között az észlelt nyomás mediátor szerepet
tölt be. Következtetések: A SATAQ-3 kérdőív magyar változata
megbízható, validitása ígéretes, ezért érdemesnek tartjuk bevezetni a hazai
kutatásba. Útmodellünk eredményei az evészavarok prevencióját elősegítő
intervenciós pontokat villantanak fel.
A szándéktól az önszabályozásig. A viselkedés előrejelzésének modelljei egészségviselkedések esetében
Authors: Berkes Tímea
Published: June 2015

Absztrakt

Elméleti háttér: Az egészségviselkedések előrejelzése elméleti
és gyakorlati szempontból is fontos az egészségpszichológia számára; e célból
számos pszichológiai modell született. Cél: A tanulmány célja,
hogy a szándék—viselkedés kapcsolatára épülő hagyományos modelltől (tervezett
viselkedés elmélete, Ajzen, 1991) — a modell részletes bemutatása után —
eljusson a szándék kialakulása utáni szakaszt önszabályozási folyamatként
értelmező modellig, az önszabályozás időbeli elméletéig (Hall & Fong, 2007).
Módszer: Narratív áttekintés. Eredmények:
A metaelemzések szerint a modell a szándék varianciájának 39—44%-át, a
viselkedés varianciájának pedig 19—34%-át magyarázza. A viselkedés
megmagyarázott varianciája nagymértékben függ a vizsgált viselkedéstől, az ezzel
kapcsolatos eredmények azonban ellentmondásosak. Az empirikus eredmények
ismertetése után az észlelt viselkedési kontroll fogalmával, a viselkedés két
prediktorának szerepével, valamint az attitűd és a szubjektív norma
komponenseivel kapcsolatos vitatott kérdéseket tárgyalom. A korábbi viselkedés a
jövőbeli viselkedés legjobb prediktora; az ezzel kapcsolatos empirikus
eredmények és elméleti megfontolások bemutatása után a szándék kialakulása utáni
szakaszt önszabályozó folyamatként mutatom be. Az önszabályozás erőmodellje
szerint az önszabályozó kapacitás korlátozott, így az önszabályozást igénylő
helyzetek lemeríthetik azt. Az önszabályozás fiziológiai szabályozása összetett;
a szabályozásban részt vevő agyterületek megegyeznek a végrehajtó funkciók
szabályozását végző agyterületekkel. A glükóz önszabályozásban betöltött szerepe
viszont nem tekinthető igazoltnak. Az önszabályozás időbeli elmélete a
szakirodalom eddigi eredményeit integrálja. A szándék kialakulása utáni
időszakot az önszabályozás biológiai alapjaival, valamint a korábbi
viselkedéssel is kiegészíti. A modell feltételezi, hogy a szándék függ attól,
hogy a viselkedés pozitív és negatív következményeit időben milyen távolságra
helyezzük a viselkedéstől. Következtetések: A szándék
kialakulása utáni időszakban érdemes egyéb tényezőket is figyelembe venni. Az
önszabályozás időbeli elmélete ígéretesen kísérli meg integrálni a szakirodalom
eddigi eredményeit; gyakorlati igazolása a kutatás jelenlegi feladata.

O delineamento experimental foi o inteiramente casualizado, com quatro repetições. Para as características avaliadas periodicamente, utilizou-se o esquema de parcela subdividida com os ambientes alocados nas parcelas e as avaliações periódicas nas subparcelas. Dentre os ambientes sombreados, o cultivo do meloeiro sob a malha Aluminet(r) 30%-O foi o tratamento que mais se destacou em termos de crescimento de planta e produção de frutos
Decadal persistence of frugivorous birds in tropical forest fragments of northern Paraná
Authors: Zaiden Tiago , Marques Fernanda Cristina , Medeiros Hugo Reis , Anjos Luiz dos
Published: June 2015

Forest fragmentation is a major cause of loss of species. We evaluated the local extinction of medium-large frugivorous bird species in six forest fragments of northern Paraná: the Parque Estadual Mata dos Godoy (PEMG), the largest and most preserved forest fragment in the region, and five other fragments. Fixed-width point counts and line transects were conducted along trails in the PEMG for 10 days: from September 2010 to March 2011, and from August 2011 to November 2011. Avian surveys in each of the other forest fragments were made over four days from October to December 2011. We compared data with a previous census carried out 10 years earlier. No extinction events were recorded from the PEMG. However, the relative abundance of species significantly changed during the ten years between surveys. In all the other forest fragments at least two frugivorous bird species disappeared, and in some as many as seven. Protecting the PEMG is crucial for the maintenance of frugivorous bird populations in our studied landscape.

Authors: Akca Selen Ozakar , Gozen Duygu , Akpinar Yeliz Yelen
Published: June 2015

Summary Objective: all individuals regardless of their age or level of development require physical, emotional and cognitive preparation before an operation. It is known that the attitudes of pediatric nurses towards pediatric patients are influential on the anxiety levels of children awaiting an operation. This study aims to determine the effect of pre-op trainning on the anxiety levels of pediatric patients hospitalized for hernioplasty surgery. Methods: this cross sectional and quasi-experimental study included a total of 100 patients aged 7-12 years admitted for inguinal hernia surgery, 50 of which were the control group and 50 the experiment group. The data was gathered using the patients’ identification forms and a child steady state anxiety scale. Research data was evaluated with appropriate statistical methods. Results: the groups showed similar socio-demographic features and no statistically significant difference was observed (p>0.05). During the pre-op period neither of the groups showed any statistically significant difference in terms of both state and trait anxiety levels (p>0.05), however the experiment group showed a statistically significant drop in their anxiety levels during the post-op period (p<0.05). Conclusion: the state anxiety levels of children receiving a planned pre-op trainning are lower compared to children who did not receive such trainning. Reducing the anxiety levels of sick children is possible through giving visual and tangible information appropriate with the age and developmental level of the sick child during the pre-op period.
Obese patients lose weight independently of nutritional follow-up after bariatric surgery

Published: June 2015

Summary Objective: to examine the association between preoperative body weight, adherence to postsurgical nutritional follow-up, length of postoperative period, and weight loss during the first 18 months among adults who have undergone bariatric surgery. Methods: a retrospective cohort study was conducted on 241 consecutive patients who underwent open Roux-en-Y gastric bypass (RYGBP) from January 2006 to December 2008, in a teaching hospital in São Paulo (Brazil). Data were collected through hospital records review and the variables analyzed included sex, age, immediate preoperative weight, adherence to postsurgical nutritional visits and length of postoperative period. Proportional body weight reductions during the 18-month follow-up period were examined using generalized estimating equations. Results: 81% (n=195) of participants were female, with overall mean age of 44.4 ± 11.6 years, mean preoperative weight of 123.1± 21.2 kg and mean preoperative body mass index of 47.2± 6.2 kg/m2. The overall adherence to postoperative follow- up schedule was 51% (95%CI: 44.5-57.5%). Preoperative body weight and adherence were not associated with proportional weight reduction (Wald’s test p > 0.18). Weight loss leveled off at the end of the 18-month follow-up period for both compliant and non-compliant patients (Wald’s test p = 0.00). Conclusions: our study showed that weight loss occurred steadily over the first 18 months after RYGBP, leveling off at around 40% weight reduction. It was associated with neither presurgical weight, nor nutritional follow-up and it may be primarily dependent on the surgical body alterations themselves. This finding may have implications for intervention strategies aimed at motivating patients to comply with early postsurgical and life-long follow-up.
In-hospital mortality risk factors in community acquired pneumonia: evaluation of immunocompetent adult patients without comorbidities
Authors: Vicco Miguel Hernan , Ferini Franco , Rodeles Luz , Scholtus Patricia , Long Ana Karina , Musacchio Héctor Mario
Published: June 2015

Summary Objective: several scores were developed in order to improve the determination of community acquired pneumonia (CAP) severity and its management, mainly CURB-65 and SACP score. However, none of them were evaluated for risk assessment of in-hospital mortality, particularly in individuals who were non-immunosuppressed and/or without any comorbidity. In this regard, the present study was carried out. Methods: we performed a cross-sectional study in 272 immunocompetent patients without comorbidities and with a diagnosis of CAP. Performance of CURB- 65 and SCAP scores in predicting in-hospital mortality was evaluated. Also, variables related to death were assessed. Furthermore, in order to design a model of in-hospital mortality prediction, sampled individuals were randomly divided in two groups. The association of the variables with mortality was weighed and, by multiple binary regression, a model was constructed in one of the subgroups. Then, it was validated in the other subgroup. Results: both scores yielded a fair strength of agreement, and CURB-65 showed a better performance in predicting in-hospital mortality. In our casuistry, age, white blood cell counts, serum urea and diastolic blood pressure were related to death. The model constructed with these variables showed a good performance in predicting in-hospital mortality; moreover, only one patient with fatal outcome was not correctly classified in the group where the model was constructed and in the group where it was validated. Conclusion: our findings suggest that a simple model that uses only 4 variables, which are easily accessible and interpretable, can identify seriously ill patients with CAP
Acute pericarditis

Published: June 2015

Summary Acute pericarditis is a common disease caused by inflammation of the pericardium, usually benign and self-limited and can occur as an isolated or as a manifestation of a systemic disease entity. Represents 5% of all causes of chest pain in the emergency room. The main etiology are viral infections, although it can also be secondary to systemic diseases and infections. The main complication of acute pericarditis is pericardial effusion, triggering a cardiac tamponade. The first line of treatment is the use of anti-inflammatory and or acetylsalicylic acid. Most patients have a good initial response to an NSAID associated to colchicine and became asymptomatic within a few days. This review article seeks to contemplate the main clinical findings and armed investigation to optimize the diagnosis of this important disease, as well as addressing their therapeutic management.
The imperative of images: construction of affinities through the cuse of digital media
Authors: Beleli Iara
Published: June 2015

Based upon ethnographic research conducted in relationship sites and applications used by people seeking affective/sexual relationships, the present article analyzes how digital media has been incorporated into the daily lives of heterosexual women aged 35-48, understood to be "independent" and "middle class" and residing in the city of São Paulo, Brazil. Autonomy, liberty and affinity are recurrent terms in the narratives of these women, leading us to questions regarding what is involved in their choice of partners whose affinities are described in terms of their similarities with the women's levels of social and cultural capital. These affinities are initially perceived through the digital circulation of photos, which are read not only according to the physical appearance of their subjects, but also according to their surroundings - objects and landscapes - which provoke the imagination with regards to the subjects' "lifestyles". Looking at the play of these new dynamics, I seek to understand how differences (in terms of class, generation, race/color, localization, etc.) operate in women's selection of partners.
Governing virtual bodies and intimacies : Cybermarriage industries between the United States and Latin America
Authors: Schaeffer Felicity Amaya
Published: June 2015

This article explores the ways the foreign emerges as a fantasy of mobility in the Cybermarriage Industry uniting Mexican and Colombian women with U.S. men. While some women use the marketing of their bodies as passionate and erotic to attract opportunities such as marriage with U.S. men, Internet scholars during the 1990s celebrated the Internet as a utopian space for enacting oneself outside the limitations of the physical body. These theories, I argue, lack an analysis of the state and the political economy in their post-body analysis of Internet exchanges.
Feminisms on the web: lines and forms of action in contemporary feminist debate*
Authors: Ferreira Carolina Branco de Castro
Published: June 2015

The present article seeks to understand the uses of the internet as a space for action and reflection among feminist groups in the Brazilian scene. It takes as its focus the relationships between new feminist generations and esthetics and the social space of the internet. Several feminist groups have emphasized the use of the internet and social networks as relevant platforms for organization, news and political expression. I thus take as my object of analysis one of the most important blogs in the Brazilian context: Blogueiras Feministas (Feminist Bloggers - BF), seeking to use this as an ethnographic resource in order to understand the set of actors and collectives working within this feminist scenario, as well as the spaces and social, political and cultural strategies that appear within it.

Este texto discute as implicações sociais das novas tecnologias de informação e comunicação (TICs) sobre o trabalho, a partir de uma perspectiva de gênero. Como parte de uma pesquisa realizada pela CEPAL em três países da América Latina, entre os quais o Brasil, ele se baseia em um estudo de caso realizado numa fábrica do setor eletroeletrônico na Região Metropolitana de Campinas, Estado de São Paulo. As conclusões do estudo indicam que, tal como apontado em análises anteriores, o trabalho das mulheres não vem sendo enriquecido com a introdução das novas tecnologias.
"Subversivas": "Malas madres" y familias "desnaturalizadas"
Authors: Regueiro Sabina Amantze
Published: June 2015

Este artículo analiza la perspectiva familiarista de la última dictadura militar argentina (1976-1983) sobre las militantes de organizaciones político-militares construidas como "malas madres/madres desnaturalizadas". Hundiendo sus raíces en las tradiciones del eugenismo, el higienismo y el catolicismo, las categorías de "abandono", "peligro" y "herencia" de la "subversión", se instrumentaron para justificar la "salvación" de sus hijos/as, y así de la sociedad, apropiándose criminalmente de los/as niños/as. De esta manera, el estudio de este caso paradigmático, pretende contribuir al campo de discusión en torno a la rica y compleja relación entre parentesco, género y política.

Authors: Ebert Michele , Lorenzini Elisiane , Silva Eveline Franco da
Published: June 2015

Childhood autism is characterized by severe and global impairment in several areas of human development and demands extensive care and dependence on the parents. The objective of this study was to understand the perceptions of mothers of children with autism regarding changes suffered by the child and their trajectories in search of an autism diagnosis. This is an exploratory descriptive study with a qualitative approach conducted with ten participant mothers. Data were collected in 2013 by means of semi-structured interviews. Thematic content analysis produced the following categories: perceptions of mothers as to changes in behaviour and/or development of their children; and trajectories of mothers in search of a diagnosis for their children. After the perception of changes in behaviour/development, mothers face an arduous trajectory of healthcare service utilization.

The aim of this study was to identify mental health care technologies for treating crack users in a Psychosocial Care Center for Alcohol and other Drugs (CAPsad, as per its acronym in Portuguese). A qualitative, evaluative case study was developed in a CAPSad, using fourth generation evaluation. Data collection occurred from January to March 2013 by means of semi-structured interviews applied to 36 subjects, these being health care professionals, patients, patients' relatives and managers. Data analysis identified the category strategies in mental health work. Results showed that recovery programs should provide spaces for dialogue, aiming to clarify the process of psychiatric internment to the user and family, and involve these in the therapy, implementing educational practices and ongoing consideration of mental health activities. In conclusion, it is important to discuss the technologies used in everyday care services, in light of the complexity of crack use.

The aim of this study was to comprehend the meaning of using illness narratives to raise awareness among nursing students and healthcare professionals toward the family-centred care model. The adopted methodological framework was Qualitative Content Analysis based on the philosophy of Family-Centered Care. Data were collected by means of assessments provided by 29 participants at an event in 2013, in São Paulo. The resulting analytical category was "transformed by the family narrative", which consisted of three sub-categories: Favours a better understanding of the family's experience; facilitates learning of family issues; and triggers thought on family-centered care. Results showed that hearing the family narrative on experiences with illness and hospitalization raises awareness among nursing students and healthcare professionals toward the family-centered care model, and facilitates learning of this model of care.

Published: June 2015

This study aimed to describe the sociodemographic and academic characteristics of nursing students from four Brazilian Educational Institutions. It is a prospective cross-sectional study. The data were collected between April 2011 and March 2012, through a survey form with questions about sociodemographic and academic characteristics of the students. The participants were graduate students enrolled in the nursing course, aged 18 years or older. 705 students participated, and these were mostly women, single, childless, who lived with their families, did not take part in sport activities and performed leisure activities. Also, most students do not participate in research groups, were not granted scholarships, are not employed, are satisfied with the course and do not intend to leave it. This study may become an important tool for the development of strategies that address the needs of students and also improve the quality of the teaching and learning process, reducing dropout rates.

Authors: Atallah Claudia Cristina Azeredo
Published: June 2015

Pretende-se, neste artigo, propor um estudo dos conflitos entre o governador da Capitania de Minas Gerais (1721-1732), Dom Lourenço de Almeida, e o ouvidor da Comarca de Sabará (1720-1725), José de Souza Valdes, considerando o período compreendido entre 1720 e 1725. Tomamos como referência para esta análise o estudo das redes clientelares e políticas, concedendo atenção especial ao conceito de redes governativas desenvolvido pela historiadora Maria de Fátima Gouvêa. Acreditamos ser possível identificar, a partir daí, algumas práticas políticas inerentes à sociedade de Antigo Regime em Portugal e seus domínios, bem como as relações estabelecidas entre as redes locais nas Minas e o Reino.
Política e economia na Terceira República francesa: Emile Moreau e a batalha do franco
Authors: Arthmar Rogério
Published: June 2015

O artigo trata da estabilização do franco, ocorrida no segundo semestre de 1926, privilegiando a perspectiva fornecida pelos registros diários do novo diretor geral do Banco da França à época, Emile Moreau. Na primeira parte, procede-se a uma reconstrução do quadro político francês na fase de dissolução do Cartel des Gauches. A seguir, examinam-se as novas bases de estabilização da moeda propostas pelo Comité d'Experts, juntamente com os determinantes da remoção da cúpula dirigente do Banco da França pelo ministro das finanças Joseph Caillaux. Após, são apresentadas as principais medidas de política monetária adotadas por Moreau, bem como suas divergências com o primeiro-ministro, Raymond Poincaré, a respeito da estratégia de recuperação econômica do país. Ao final, avalia-se até que ponto as visões de Poincaré e Moreau realmente se distanciavam em relação à magnitude mais conveniente de estabilização do câmbio.

Published: June 2015

Resumo Este artigo apresenta uma proposta de metodologia para identificação de redes de rotas cicláveis onde as condições de circulação indesejáveis percebidas por usuários de bicicletas são minimizadas. Um modelo matemático baseado em um algoritmo de busca de caminhos é definido para encontrar rotas com melhor nível de serviço para bicicletas (NSB). O Método de Dixon (1996) foi definido para a avaliação do NSB, ao qual uma etapa de análise de declividade de vias foi incorporada através da comparação de cinco critérios (FHWA, 1979; AASHTO, 1999; Road Directorate, 2000; GEIPOT, 2001a; Austroads, 2011). Essa metodologia foi aplicada em Montes Claros, MG, para identificar uma rede cicloviária que interliga cinco pólos geradores de viagens. Neste estudo, as rotas cicláveis mais adequadas foram obtidas através do estudo da rede viária definida pelo critério de declividade de FHWA, embora uma pequena variação do NSB das rotas tenha sido observada quando avaliadas pelos critérios de FHWA, AASHTO e Austroads. Destaca-se que a etapa de avaliação comparativa entre critérios de declividades no modelo permitiu a identificação de rotas similares às utilizadas por usuários de bicicletas do município.

Published: June 2015

Objective: To compare the spelling ability of schoolchildren from the fourth to sixth grades of the elementary schools in the private and public schools of Bauru, São Paulo, and to verify whether errors are overcome as studies progress and the hierarchy of errors as to how often they occur. Methods : A dictation was applied to 384 schoolchildren: 206 from the private schools: 74 were at the fourth grade, 65 at the fifth grade, and 67 at the sixth grade; and 178 from the public schools; 56 at the fourth grade, 63 at the fifth grade, and 59 at the sixth grade of elementary school. Student's t test was used. Results: In comparison of total spelling errors score, difference was found among the fourth and sixth grades of the private and public schools. Spelling errors decreased as education progressed, and those related to language irregularities were more common. Conclusion: Spelling ability and performance of students from the private and public schools are not similar in the fourth and sixth grades, but it is in the fifth grade. Spelling errors are gradually overcome as education progresses; however, this overcome rate was considerable between the fourth and fifth grades in the public schools. Decrease in the types of spelling errors follows a hierarchy of categories: phoneme/grapheme conversion, simple contextual rules, complex contextual rules, and language irregularities. Finally, the most common type of spelling error found was that related to language irregularities.

Purpose: To verify the efficacy of a perceptual and visual-motor skill intervention program for students with dyslexia. Methods: The participants were 20 students from third to fifth grade of a public elementary school in Marília, São Paulo, aged from 8 years to 11 years and 11 months, distributed into the following groups: Group I (GI; 10 students with developmental dyslexia) and Group II (GII; 10 students with good academic performance). A perceptual and visual-motor intervention program was applied, which comprised exercises for visual-motor coordination, visual discrimination, visual memory, visual-spatial relationship, shape constancy, sequential memory, visual figure-ground coordination, and visual closure. In pre- and post-testing situations, both groups were submitted to the Test of Visual-Perceptual Skills (TVPS-3), and the quality of handwriting was analyzed using the Dysgraphia Scale. Results: The analyzed statistical results showed that both groups of students had dysgraphia in pretesting situation. In visual perceptual skills, GI presented a lower performance compared to GII, as well as in the quality of writing. After undergoing the intervention program, GI increased the average of correct answers in TVPS-3 and improved the quality of handwriting. Conclusion: The developed intervention program proved appropriate for being applied to students with dyslexia, and showed positive effects because it provided improved visual perception skills and quality of writing for students with developmental dyslexia.

Purpose: To examine the voice and personality characteristics of patients diagnosed with organic dysphonia secondary to vocal fold immobility. Methods: The study comprised patients of both genders, attending the Clinic School of Speech Therapy of the Federal University of Paraíba, with otorhinolaryngological diagnosis of vocal fold immobility and speech therapy diagnosis of dysphonia. The self-assessment of voice was measured through a Vocal Screening Protocol and Voice Symptoms Scale (VoiSS), the voice was collected for auditory-perceptive evaluation, and the Factorial Personality Battery (FPB) was used. Descriptive statistical analysis was performed to determine the frequency, mean, and standard deviation of the studied variables. Results: Eight patients participated in the study, of both genders, with average age of 40.4±16.9 years. The more frequent risk factors were the personal ones (4.7±2.1). In the VoiSS, the patients presented a higher average in the limitation score (34.1±15.7). From the auditory-perceptive evaluation, moderate intensity of vocal deviation was obtained, with predominant vocal roughness (57.7±25.2). In the FPB, the patients had an average higher than the cutoff scores in neuroticism (3.8±1.4) and accomplishment (5.2±1.0). Conclusion: The predominant vocal parameter was roughness. The patients referred to a few risk factors that compromise the vocal behavior and presented the neuroticism and realization factors as a highlight in their personality. Thus, individuals with vocal fold immobility show personality characteristics that may be a reflection of their voice disorder, not a factor that determines their dysphonia.

Published: June 2015

Purpose: To perform an integrative review of scientific bibliographic production on the use of superficial heat treatment for temporomandibular disorders. Research strategy : Literature review was accomplished on PubMed, LiLACS, SciELO, Bireme, Web of Science, and BBO databases. The following descriptors were used: hot temperature, hyperthermia induced, heat transference, temporomandibular joint, temporomandibular joint disorders, temporomandibular joint dysfunction syndrome, and their equivalents in Portuguese and Spanish. Selection criteria : Articles that addressed the superficial heat for the treatment of temporomandibular disorders, published in English, Spanish, or Portuguese, between 1980 and 2013. Data analysis : The following data were collected: technique of applying superficial heat, duration of application, stimulated body area, temperature of the stimulus, frequency of application, and benefits. Results : initially, 211 studies were found, but just 13 contemplated the proposed selection criteria. Data were tabulated and presented in chronological order. Conclusion: Several techniques for superficial heat application on treatment of temporomandibular disorders were found in the literature. The moist heat was the most widely used technique. Many studies suggested the application of heat for at least 20 minutes once a day. Most authors recommended the application of heat in facial and cervical regions. The heat treatment resulted in significant relief of pain, reduced muscle tension, improved function of the mandible, and increased mouth opening.

Authors: Silva-Munhoz Lenice de Fatima da , Bühler Karina Elena Bernardis , Limongi Suelly Cecilia Olivan
Published: June 2015

Purpose: To verify the accuracy of clinical evaluation compared with videofluoroscopic swallowing studies in the detection of isolated laryngeal penetration and laryngeal aspiration in children with suspected dysphagia; to identify clinical signs and symptoms associated with isolated laryngeal penetration and laryngeal aspiration; and to determine the sensitivity and specificity of the clinical signs and symptoms identified. Methods: Retrospective analysis of data from clinical and videofluoroscopic evaluations carried out in 55 children from 1 month to 7 years and 11 months old. For clinical assessment, the Protocol for Clinical Assessment of Pediatric Dysphagia was used. The sensitivity, specificity, and positive and negative predictive values of clinical evaluation were analyzed. For statistical analysis, the Fisher's exact and χ2 tests were used. Results: Clinical evaluation showed, in general, a sensitivity of 86% and a specificity of 32%. For isolated laryngeal penetration, clinical evaluation showed a sensitivity of 88%. For laryngeal aspiration, clinical evaluation showed a sensitivity of 86%. However, the specificity values were low for both alterations. There was no association between clinical evaluation and videofluoroscopic findings. Choking was the only clinical sign associated with isolated laryngeal penetration thin fluid and showed a sensitivity of 53% and a specificity of 77%. Conclusions: Clinical evaluation was sensible to detect isolated laryngeal penetration and laryngeal aspiration in children with suspected dysphagia. However, it showed a low specificity. Choking was the only clinical sign associated with isolated laryngeal penetration of thin fluid. More prospective studies are needed to confirm these findings in this population.
