The geological structure of Kastas hill archaeological site, Amphipolis, eastern Macedonia, Greece
Authors: Syrides George , Pavlides Spyros , Chatzipetros Alexandros
Published: November 2017

This paper presents research results on the geological structure of Kastas hill in Amphipolis, as well as the broader area. They consist of geological and geomorphological observations at Kastas and 133 hills and the surrounding areas, on their geological structure, the stratigraphy and the paleoenvironment. Kastas hill is the site of the largest burial mound discovered in Greece to date. The slopes of its embankment were recorded and modelled in detail using near field photogrammetry. The problem of distinguishing between in situ geological formations and ex situ anthropogenic deposits is also addressed. The bulk volume of Kastas hill consists of natural sediments; these sediments are exposed as successive alternating beds of grayish loose and cohesive sands with scattered pebbles and locally with cobbles. Clayey beds up to ~20-30 cm thick intercalate between the sands. At the top of the hill the anthropogenic deposits are typical of Macedonian tumuli, with soil and clay alternations for sealing and stabilizing them. Paleosoil horizons were observed both in natural sediments and within anthropogenic substrates. Two horizons were sampled for dating by different methods (OSL – optical stimulated luminescence and 14C – Accelerated Mass Spectroscopy). Their dating shows the development of successive deposits during the Iron, Archaic and Classical ages. The AMS dating of a charcoal which is closely associated to the construction of the main monument yielded an age of Cal. BP 2310 = Cal. 360 BC.

Ιδιωτικοποίηση και πανεπιστημιακή εκπαίδευση: Τι διακυβεύεται;
Authors: Τσακαλώτος Ευκλείδης
Published: November 2017

Αυτό το άρθρο εξετάζει τη φύση της εκπαίδευσης ως αγαθό. Πρώτα παρουσιάζει την προσέγγιση που κυριαρχεί στην οικονομική βιβλιογραφία και υποστηρίζει ότι η εκπαίδευση, παρόλο που δεν μπορεί να θεωρηθεί ως κοινωνικό αγαθό υπό τη στενή (τεχνική) έννοια του όρου, εντούτοις εμπεριέχει έναν μεγάλο αριθμό χαρακτηριστικών που τη διαφοροποιούν εμφανώς από τα συνηθισμένα ιδιωτικά αγαθά. Η διερεύνηση της μη-οικονομικής βιβλιογραφίας δίνει έμφαση σ’ αυτή την ειδική φύση της εκπαίδευσης ως αγαθού. Γι ’ αυτόν το λόγο το άρθρο διατυπώνει αντιρρήσεις στα επιχειρήματα όσων υποστηρίζουν ότι η ιδιωτικοποίηση και οι αγοραίες μέθοδοι μπορεί να γίνουν τα θεμέλια αναβάθμισης της πανεπιστημιακής εκπαίδευσης.
Εξουσία και πολιτική εκκλησιολογία στη δυτικοευρωπαϊκή μεσαιωνική πολιτειολογική σκέψη
Authors: Γκότσης Γεώργιος Ν.
Published: November 2017

Στόχος αυτής της μελέτης είναι η ερμηνεία και διασάφηση της μεσαιωνικής σύλληψης της εξουσίας σε σχέση προς τις ευρύτερες χρονικές, πνευματικές και οντολογικές δομές του ανθρώπινου πράττειν. Αφετηρία αποτελεί η υπόθεση ότι τα ειδικότερα θεσμικά και πολιτικά δόγματα του μεσαιωνικού παπικού status εδράζονται σε μία θεμελιώδη αρχή πολιτικής εκκλησιολογίας, η ανακατασκευή της οποίας μπορεί να διενεργηθεί μέσω της διερμήνευσης ενός εκτεταμένου πραγματολογικού υλικού. Ακολουθώντας την κατεύθυνση μιας κριτικής ανασύστασης του εγκόσμιου και εκκλησιαστικού ορίζοντα τον μεσαιωνικού πολιτικού στοχασμού, η ερμηνευτική απόπειρα υποβάλλει σε λεπτομερή μελέτη τις κύριες πτυχές ενός κανονιστικού πολιτειολογικού υποδείγματος, Προβαίνει περαιτέρω στη συνεκτίμηση παραμέτρων όπως οι θεωρίες περί διακυβέρνησης, η σχέση πολιτικών και νομικών επιχειρημάτων, η συμβολή του ρωμαϊκού δικαίου και οι εφαρμογές τον στο πεδίο της πολιτικής οργάνωσης, η φύση της θρησκευτικής αυθεντίας και τα ζητήματα νομιμοποίησης. Προεξέχουσα έμφαση αποδίδεται στις ιδέες εκείνες που ευνόησαν την ανάδυση του μοντέρνου κράτους και επέτρεψαν τη διαμόρφωση μιας εναλλακτικής προσέγγισης με όρους συμβολαίου, συγκατάθεσης και κοινού οφέλους. Η ιστορική και βαθμιαία απαξίωση των παπικών αξιώσεων εγκυρότητας και ισχύος, όπως και η συνηγο- ρία υπέρ μιας βολονταριστικής δόμησης των πολιτικών υποκειμένων, μπορούν να θεωρηθούν ως αναγκαίες συνθήκες εισόδου στην εκκοσμικευμένη κοσμοεικόνα του αναγεννησιακού ανθρωποκεντρισμού.

Published: November 2017

The main direction of development of machines for minimal soil cultivation is the intensification of the technological process by combining several operations. In this case, the most appropriate way to increase productivity, reduce energy consumption and improve the quality of work should be considered the use of the sliding cutting effect in them, as well as the fulfillment of the condition for guaranteed movement of the soil layer relative to their working surface. The article presents the results of studies of combined working units indicators of a tillage. Based on the results of laboratory studies and field experiments, the degree of soil crumbling, the leveling of field surface, the range of soil discarding, etc. have been determined. The production tests of combined tillage tools with the proposed working units confirmed the conclusions that it significantly improves the quality of minimal tillage and ensures a higher crop yield on average by 13.5% (compared to the existing unit KPS-4 + PP).
RESEARCH ON QUALITY AND GRAIN PRODUCTION EFFICIENCY

Published: November 2017

Grain production has always been and is a strategic branch of the country’s economy. Grain, being the main food for people, presents itself as a necessary element of fodder for the production of livestock products. Therefore, the grain industry is an indicator of the level of development not only of agriculture, but also of the country’s economy as a whole. In addition, grain acts as a technical crop, as a raw material for the production of alcohol, starch and biofuel. Grain production is a source of income for agricultural producers. It is easily possible to realize as it is constantly demanded production. But here it should be noted the need to continuously increase production volumes, both by expanding the sowing areas, and increasing the productivity. So it is necessary to work on improving technology, applying fertilizers, plant protection products against pests and diseases. In order to increase the economic efficiency of grain production for agricultural producers, along with the increase in output, special attention should also be paid to product quality. In many farms, more accurately in most of them, the quality of grain is low, the content of gluten in it is only 14-17%, and therefore it can be used only as feed for livestock, as it does not meet the requirements of food grains. In this regard, as a result, the low price of its sale, which leads to low profitability of agricultural producers. As a result of our research, it is established that 70-75% of grain in the Republic of Tatarstan does not meet the food criteria. Rainy summer of this year formed a record harvest not only for winter crops, but also for all spring crops. At the same time, it is the main factor of poor quality products. However, there are many examples where, in such conditions, they have obtained high-quality grain. A positive example is the activity of “Krasnyy Vostok”, agricultural holding, where the gluten content is 27-28%. This is achieved through the use of promising varieties, for example winter wheat “Moskovskaya 39”, and “Moskovskaya 40”. We studied the territory of the Volga of Zelenodolsky municipal district, where 32.7 thousand hectares is the land use of “Krasnyy Vostok” agricultural holding. Here, the productivity of winter wheat of these varieties was 56 centners per hectare in standings at the elevator. The gluten content was 27-28%. This indicator is only at a level of 14-16% at all neighbors. We have established the factors that led to such high results.
Penalizing Physicians for Low‐Value Care in Hospital Medicine: A Randomized Survey
Authors: Liao Joshua M. , Navathe Amol S. , Schapira Marilyn M. , Weissman Arlene , Mitra Nandita , Asch David A.
Published: November 2017

Low‐value services—those for which there is little to no benefit, little benefit relative to cost, or outsized potential harm compared with benefit—persist widely despite professional consensus, guidelines, and national campaigns to reduce them. As policy makers consider financially penalizing physicians to deter low‐value services, physician support for such penalties remains unknown. We conducted a randomized survey experiment among physicians to evaluate how the framing of harms from low‐value care—in terms of those to patients, healthcare institutions, or society—influenced physician support of financial penalties for low‐value care services. Policy support rate was 39.6% overall and highest when the harms of low‐value care were framed as costs to society (48.4%). Compared with respondents receiving the “patient harm” version, those receiving the “societal harm” version (adjusted odds ratio [OR] 2.83; 95% confidence interval [CI], 1.20‐6.69), but not the “institutional harm” framing (adjusted OR 1.53; 95% CI, 0.66‐3.53), were more likely to report policy support. Our results suggest that emphasizing the impact of these harms may increase acceptability of financial penalties among physicians and contribute to the larger effort to decrease low‐value care in hospital settings.
Atypical myopathy
Authors: Naylor Rosie J
Published: November 2017

Atypical myopathy (AM) is a severe non-exertional myopathy that affects horses at pasture. AM is caused by ingestion of the toxin hypoglycin A, found in the seeds, leaves and seedlings of sycamore trees. Hypoglycin A blocks aerobic energy metabolism in muscle fibres. Most commonly the disease occurs during the autumn and occasionally the spring months, often following periods of wet and windy weather. A definitive diagnosis requires analysis of plasma acylcarnitines or urinary organic acids, which confirms the metabolic disturbance. Treatment is symptomatic and includes fluid therapy, nutritional support and providing analgesia, while supporting mitochondrial function. The prognosis is guarded, with very high mortality rates reported.
Cellulitis and lymphangitis
Authors: Rendle David
Published: November 2017

Cellulitis is a common condition in equine practice and one that is frustrating to treat. Typically, antimicrobials and anti-inflammatories are administered and most cases resolve with time. Bacterial culture and susceptibility should be performed more frequently as they enable more responsible and informed decisions on antimicrobial choice to be made, especially when first ineffective. In cases that are refractory to initial treatment imaging modalities play a role in providing a better understanding of the extent of the underlying pathology and hence prognosis. Recurrence is common.

Exploring intentional use of a technological proxy, Turnitin, to enhance student academic literacy practices
Authors: Orlando Joanne , Hanham Jose , Ullman Jacqueline
Published: November 2017

Current pedagogical practices have seen the rapid spread of technological tools that carry out tasks on behalf of the learner; we use the term technological proxy to refer to these tools. A popular technological proxy used by students worldwide is a text-matching software called Turnitin. Turnitin alerts users to sections of an assignment that appear to match materials that exist in some other published or previously submitted form. This paper reports on a small case study that examined how university students use Turnitin and the implications its use has on their academic literacy practices. Drawing on theories of intentional learning, achievement goal orientation theory, and self-efficacy theory, we applied think-aloud protocols and focus groups to elicit data on students’ interpretation and use of Turnitin feedback. Results show that the majority of students used the proxy with a performance goal orientation that focused on achieving a low similarity index. This dominating goal orientation is attributed to students’ low self-efficacy for using the program, and the university’s positioning of the program as a plagiarism tool. Hands-on experience with Turnitin contributed to a shift in using the program with intentionality.
The Economic and Economic-Statistical Designs of the Synthetic Chart for the Coefficient of Variation

Published: November 2017

Control charts are one of the tools used to monitor processes based on statistical principles. Standard control charts in the literature mostly monitor changes in the mean, the standard deviation, or both. However, these charts provide dubious results when the mean is not constant and the standard deviation changes with the mean. For such processes, monitoring the coefficient of variation (CV) is a better approach. In the literature, very few studies are available on the economic and economic-statistical designs of the CV charts. This makes it difficult for practitioners who wish to implement CV charts at an economically optimal level. Thus, this paper filled the gap in research by proposing economic and economic-statistical designs for the synthetic CV chart. As it is often difficult to estimate the shift size, the designs proposed in this paper considered both the known and unknown shift size cases. For the known shift size case, the shift size needed to be specified as an exact value, while for the unknown shift size case, the shift size only needed to be specified as a range of possible values. Subsequently, a sensitivity analysis was performed to investigate the effects of different input parameters. The effects of statistical constraints and the effects of incorrect specification of the shift size were also studied. When there is uncertainty regarding the shift size, guidelines are proposed to select an appropriate range for it. Finally, comparisons were made between the synthetic, Shewhart, exponentially weighted moving average (EWMA), and cumulative sum (CUSUM) CV charts. Comparisons were also made between the zero-state, conditional steady-state, and cyclical steady-state synthetic CV charts.

Published: November 2017

The article studies the synthesis of carbon-based and amorphous silicon dioxide bisorbents. Sorption characteristics of new bases for producing modified systems to use them in electrocatalysis are presented. For preparation of SiO2/C baseas rice husk (RH) was chosen as the raw material. A series of experiments was performed to optimize parameters of the RH carbonization by varying temperature and time of the process. The material obtained from the RH thermal destruction products was modified by the heteropoly compound (NH4)3[Co3O6Mo6O18H6] · nH2O and thermally reduced by hydrogen. The registration of the voltammetric curves was carried out at pH = 6.22 in the background electrolyte of 0.1 M Na2SO4 and pH = 4.45 in 0.1 M KC8H5O4.The potential ranges were -1.2В – 1.2 V and -1.0 V – 0.2 respectively. The mechanism of the electrochemical processes on these materials has been studied. It is shown that the obtained composite electrode materials exhibit electrochemical activity in the investigated potential regions, and they are characterized by the stability of redox properties. The main ways of using the obtained composites are outlined.

Published: November 2017

Profiles, Dynamics and Challenges of the Costa Rican Education is a program planned to be executed in a five-year period: 2014-2018. It is being executed within the framework of processes of research, teaching, university extension, and production of the Center for Research and Teaching in Education (CIDE in Spanish) of the National University of Costa Rica. This proposal considers the implementation of two sub-programs approaching two important areas: pedagogical innovation, and the production of materials and didactic technological resources. The first sub-program, Innovation, is oriented to highlighting and valuing the set of practices and successful experiences in the field of teaching, and assuming processes associated to it, such as the professional practice activities and the graduation final work proposals in different modalities. The second sub-program, Production of Didactic Technological Resources, supports the development of projects through consulting, design, and production of materials and didactic technological resources. This paper describes the methodological route proposed for the Production sub-program, along with some of the preliminary results achieved at the beginning of the implementation of the proposal. Finally, the article presents a series of reflections about the diverse dimensions that the program covers, its scope, impact, challenges, and constraints that must be assumed, as well as the different contributions in the four substantive areas on which the National University of Costa Rica bases its work: teaching, research, university extension and production.

Journals tend to be regional in the sense that their readership usually focuses on its own personal scope. For instance, it is hard to find a truly international journal with papers from many different countries. However, this time Profile journal has made a major effort to obtain valuable contributions from beyond the South American continent. In fact, this special issue brings together a number of very appealing topics which reflect on a common tendency. There is a clear orientation towards technology-based language teaching which can be seen in many parts of the world.
Grabbing Dignity
Authors: Roa Pilar Cristian Felipe
Published: November 2017

‘Grabbing Dignity’ explores how marginalised women perceive their dignity during a relocation process from an illegal settlement to subsidised housing in Santiago, Chile, in 2016.Through an ethnographic-based approach, the film experiments with different audiovisual language techniques, where observational cinema, semi-structured interviews and voice over are combined to build a reflective storytelling about a year-long fight for housing rights.This film points out that the fight for dignity is not driven by seeking material goods for improving their quality of life, but rather as finding a legitimate and embodied sense of place where the locals are accepted by the wider Chilean society, and by that acceptance also recognised as human beings. I portray that this fight is contrasted by how the relocation is carry out by the Chilean government where house and home are inaccurately taken as equals. With this in mind, the film enlarges the discussion about human dignity as not only an individual perception, but also as a community-based phenomenon. From this perspective, I suggest that a collective sense of place is paramount in achieving a better understanding of what human dignity might encompass.
The Possibility of Spirits
Authors: Van de Port Mattijs
Published: November 2017

What is it that you film when you film a spirit?Shot in Bahia (Brazil), The Possibility of Spirits is an essay film that keeps the baffling mystery of spirit possession center stage. In a poetic assemblage of images and words, it offers an alternative for the kind of documentary that either exoticizes spirit possession in spectacular imagery, or extinguishes the wonder of the phenomenon in explanatory prose.Possession ceremonies are filmed in close up, but the images first and foremost reveal that we don't know what it is that we are looking at. Words -- of the filmmaker, as well as of his interlocutors -- are allowed to drift out of meaning. Trying to grasp the phenomenon, they become silence, or laughter, or screaming. Paying tribute to the extra-ordinariness of its subject matter, this film invites viewers to allow themselves to be confused and -- in that confusion -- consider the possibility of spirits.

Published: November 2017

RESUMO A vergonha, entendida como uma emoção autoconsciente, multifacetada e socialmente focada, desempenha um papel central na saúde mental dos indivíduos. Nos adolescentes, é também uma experiência frequente, sendo importante a sua avaliação para a investigação e prática clinica. Este estudo pretende validar uma medida breve de vergonha externa (Escala de Vergonha Externa - Versão breve para Adolescentes [OASB-A]). Participaram 834 adolescentes com uma média de 15 anos. O modelo final da OASB-A (8 itens), obtido por meio da Análise Fatorial Confirmatória, apresenta um bom ajustamento aos dados, invariância para o sexo, boa consistência interna e fidedignidade temporal adequada. As correlações com as experiências traumáticas de vergonha (IES-R) e sintomatologia psicopatológica (DASS-21) são significativas. A OASB-A é uma medida válida e econômica para avaliação da vergonha externa em adolescentes.

Published: November 2017

RESUMO O estudo investigou o envolvimento paterno de 27 pais adultos que tinham um filho/a com 24 meses. As respostas dos pais foram examinadas através de análise de conteúdo, com base em três dimensões: interação, disponibilidade e responsabilidade. Os resultados revelaram que os pais se relacionavam com o filho conforme as necessidades e capacidades da criança, entre elas a de mais autonomia. Os pais relataram que se envolviam em atividades de cuidado, sobretudo auxiliando o filho a dar conta de suas demandas. Também destacaram que interagiam e estavam disponíveis para o filho e revelaram preocupações sobre ele. Entretanto, a participação do pai foi percebida como menor quando comparada à da mãe, mesmo quando o pai compartilhava os cuidados e as responsabilidades.
Considerações sobre a Causalidade Psíquica e a Escolha na Psicanálise
Authors: Costa Germano Quintanilha , Gomes Gilberto
Published: November 2017

RESUMO Freud, ao elaborar sua metapsicologia, buscando explicações para a vida psíquica e seus fenômenos, acaba deparando-se com a velha questão filosófica a respeito do determinismo e do livre arbítrio. É evidente que o prisma pelo qual Freud desenvolveu sua teoria é completamente diferente dos demais campos do saber. No entanto, o enigma era o mesmo. O que significavam, para a teoria psicanalítica, os fenômenos psíquicos estudados por Freud? Eram eles produtos do acaso, da liberdade consciente, ou resultados de algum determinismo? Investigamos neste trabalho como os conceitos psicanalíticos de inconsciente, causalidade psíquica, sobre-determinação e escolha se articulam a essas questões.
Análise de sobrevivência de mulheres com câncer de mama: modelos de riscos competitivos
Authors: Ferraz Rosemeire de Olanda , Moreira-Filho Djalma de Carvalho
Published: November 2017

Resumo O objetivo deste estudo foi estimar os efeitos de fatores prognósticos na sobrevida do câncer de mama, como idade, estadiamento e extensão do tumor, utilizando modelos de riscos proporcionais de Cox e de riscos competitivos de Fine-Gray. É um estudo de coorte retrospectiva de base-populacional referente a 524 mulheres diagnosticadas com câncer de mama no período de 1993 a 1995, acompanhadas até 2011, residentes no município de Campinas, São Paulo, Brasil. O ponto de corte (cutoff) da variável idade foi definido utilizando-se modelos simples de Cox. Nos ajustes de modelos simples e múltiplo de Fine-Gray, a idade não foi significativa na presença de riscos competitivos e nem nos modelos de Cox, considerando-se, para ambas as modelagens, óbito por câncer de mama como desfecho de interesse. As curvas de sobrevidas estimadas por Kaplan-Meier evidenciaram diferenças expressivas para óbitos por câncer de mama e por riscos competitivos. As curvas de sobrevida por câncer de mama não apresentaram diferenças significativas quando comparados os grupos de idades, segundo teste de log rank. Os modelos de Cox e de Fine-Gray identificaram os mesmos fatores prognósticos que influenciavam na sobrevida do câncer de mama.

Resumo Devido à alta prevalência do uso de cadeira de rodas por idosos institucionalizados, objetivou-se verificar se os fatores sexo, idade, escolaridade, tempo de admissão, comorbidades, cognição e funcionalidade estão associados ao uso deste dispositivo, como também averiguar os motivos que podem levar a essa utilização segundo a percepção dos idosos. Estudo transversal e descritivo, incluídos 55 idosos subdivididos em G1 (locomoção sem auxílio) e G2 (cadeirantes). Análise do perfil através dos prontuários, cognição e funcionalidade pelo Mini-Exame do Estado Mental e Índice de Barthel. Foram questionados 33(60,0%) cadeirantes no G1 e 22(40,0%) no G2 sobre os fatores que os levaram à utilização da cadeira de rodas. Houve diferença entre os grupos em relação à funcionalidade (p = 0,005). O idoso que não tem acidente vascular encefálico tem menor chance de utilizar cadeira de rodas (OR:0,09; IC95%:0,02-0,36). Idosos cadeirantes relataram: medo de cair, dor, cansaço, fraqueza nas pernas, dificuldades de caminhar e falta de auxílio na deambulação. O acidente vascular encefálico e a funcionalidade estão associados ao uso de cadeira de rodas. O conhecimento destes fatores e dos motivos relatados pelos idosos pode permitir que alternativas de prevenção sejam traçadas.

Abstract The purpose of this study was to determine the relationship between peak cadence indicators and body mass index (BMI) and body fat percentage (BF%)-defined weight status in children. The sample comprised 485 Brazilian children. Minute-by-minute step data from accelerometry were rank ordered for each day to identify the peak 1-minute, 30-minute and 60-minute cadence values. Data were described by BMI–defined and bioelectrical impedance-determined BF% weight status. BMI-defined normal weight children had higher peak 1-minute (115.5 versus 110.6 and 106.6 steps/min), 30-minute (81.0 versus 77.5 and 74.0 steps/min) and 60-minute cadence (67.1 versus 63.4 and 60.7 steps/min) than overweight and obese children (p<.0001), respectively. Defined using %BF, normal weight children had higher peak 1-minute (114.5 versus 106.1 steps/min), 30-minute (80.4 versus 73.1 steps/min) and 60-minute cadence (66.5 versus 59.9 steps/min) than obese children (p<.0001). Similar relationships were observed in boys; however, only peak 1- minute cadence differed significantly across BMI and %BF-defined weight status categories in girls. Peak cadence indicators were negatively associated with BMI and BF% in these schoolchildren and significantly higher among normal weight compared to overweight or obese children.

Resumo A Constituição Federal de 1988 introduziu o Benefício de Prestação Continuada (BPC) possibilitando a inclusão de pessoas com deficiência. Estudo descritivo, com dados municipais agregados, da distribuição temporal e geográfica da incidência de microcefalia relacionada ao Zika vírus no Brasil e dados das concessões de BPC a crianças com diagnóstico de microcefalia. Apresentam-se dados sobre a demanda e a concessão do BPC para crianças com microcefalia desde 2009. Os casos de microcefalia e/ou alteração do sistema nervoso central foram obtidos do Ministério da Saúde e totalizaram 2.366 casos confirmados de 01/01/2015 a 31/12/2016. A série histórica da concessão de BPC de 2009 a 2016 foi elaborada a partir de dados do Instituto Nacional do Seguro Social e mostrou, até 2014, uma linha de base com a média de 200 benefícios anuais para crianças menores de 48 meses com microcefalia. Em 2016 as concessões aumentaram oito vezes atingindo 1.603 benefícios concedidos a crianças de 731 municípios, das 27 Unidades da Federação. A Região Nordeste concentrou 73% dos BPC concedidos, mas, ainda assim, isto representou menos do que 65% da demanda de casos incidentes. É preciso reforçar a implementação do sistema de referência integrado, inclusive com busca ativa, para que todas as crianças com direito ao BPC tenham acesso.

Resumo O objetivo deste artigo é avaliar a associação entre desigualdades sociais e autorrelato de limitações para a realização de atividades diárias, causadas por doenças crônicas ou deficiências. Inquérito nacional (Pesquisa Nacional de Saúde, 2013) que avaliou amostra de brasileiros com 18+ anos. O desfecho foi o indivíduo relatar ter suas atividades habituais limitadas moderadamente ou intensamente ou muito intensamente (Limit) devido a uma ou mais doenças crônicas, ou ainda por deficiência mental, física, auditiva ou motora. A exposição principal foi a classe econômica, classificada em cinco categorias, indo de A (mais rica) até E (mais pobre). Foi estimado um modelo de regressão logística ajustado por classe econômica e variáveis de confundimento, considerando o desenho complexo da amostra e alfa = 5%. 15,5% dos indivíduos relataram ter Limit. Comparando as classes sociais, 19,5%, 21,9%, 16,1%, 11,1%, e 7,7% indivíduos pertencentes à classe E, D, C, B e A relataram o desfecho. O modelo ajustado evidenciou maior chance dos indivíduos da classe D+E, e D, relatarem Limit do que indivíduos da classe A+B (referência). Políticas públicas de assistência à saúde e assistência social para pessoas com deficiências devem focar nas classes sociais E e D.

Published: November 2017

Resumo A presbiacusia é uma alteração prevalente na população idosa, porém subdiagnosticada, desta forma, é importante aprimorar instrumentos de triagem simples. A escala subjetiva de faces foi proposta como forma de avaliar a autopercepção auditiva do idoso e sua correlação com exames audiológicos. Foram avaliados todos os pacientes encaminhados para o serviço de audiologia de um centro de referência de atenção à saúde do idoso no período de fevereiro a novembro de 2013. Os pacientes foram examinados por meatoscopia, audiometria tonal e vocal e responderam a escala subjetiva de faces e o teste do sussurro. Participaram 164 idosos com média de idade de 77 anos. Encontrou-se boa correlação entre a escala subjetiva de faces e o limiar audiométrico (r = 0,66). Houve correspondência entre as faces e o grau da perda auditiva, sendo a face 1 correspondente a audição normal, face 2 a perda auditiva leve e face 3 a perda auditiva moderada grau I. Ao avaliar as qualidades psicométricas da escala subjetiva de faces, verificou-se que as faces 2 e 3 apresentam bons índices de sensibilidade e especificidade, com área sob a curva ROC de 0,81. A escala subjetiva de faces parece ser um bom instrumento complementar de triagem auditiva em serviços gerontológicos, de fácil aplicação e baixo custo.

Published: November 2017

ABSTRACT Before performing any financial analysis costs must be calculated. These costs should allow the planning and control over the use of the machines as well as the comparison between different investments alternatives since this is easily calculated. Generally the operating costs of forest harvesting machines are estimated until the maximum of 25,000 hours of work, and it is not possible to know whether the activity remains profitable thereafter or not. For this reason the objective of this study was to evaluate the costs from cutting activities and wood processing carried out by a forestry tractor harvester up to approximately 30,000 hours of work. Ten forest machines composed of two models of harvester (John Deere, model 1270D and 1470D) were used. A spreadsheet provided by a forestry company located in the state of Minas Gerais, containing the necessary data to estimate the operating cost of the machines and subsequent achievement of the sensitivity analysis was used. The operating cost was obtained by the sum of the fixed and variable costs. For sensitivity analysis the variation ± 20% of the most representative elements of the total cost of the machine was performed. The results for the operating cost of the harvester and forwarder was U.S. $ 190.85 h-1. Costs for repairs and maintenance, labor, fuel, and depreciation represented approximately 90% of the total cost of the machine. Despite the fact that the age of the machine has a direct influence on its operating cost, the costs did not behave in a linear fashion over the years.

ABSTRACT The objective of the present study was to test the effects of explant type, auxin concentrations, culture media, and auxin concentrations on the induction and proliferation of somatic embryos of Eucalyptus grandis x E. urophylla. Seeds and cotyledons were used as explants and inoculated in culture media containing 1.13, 2.26, 3.39 and 4.52 µM dicamba or 4.14, 10.35, 20.71 and 31.06 µM picloram. Embryogenic calli induced in the picloram treatments were used as explants and inoculated in semisolid or liquid media containing 4.14, 10.35, 20.71 and 31.06 µM picloram and keeping the origin of the embryogenic callus (seeds or cotyledons) and the concentration of picloram in those who were in the induction phase. Statistical, descriptive and anatomical analyses were performed. Induction of somatic pro-embryos into the juvenile plant material of Eucalyptus grandis x E. urophylla was performed using seeds or cotyledons as the source of explants, with the addition of dicamba and picloram as growth regulators. The use of cotyledons as a source of explants and the concentration of 4.1 µM picloram added to the culture media resulted in a higher induction of somatic pro-embryos. Proliferation of secondary somatic embryos was achieved using liquid medium added with picloram.

RESUMO A indústria do futebol chega a movimentar em todo mundo, por ano, de acordo com Belo e Paolozzi (2013), um valor entre US$ 400 bilhões e US$ 1 trilhão. Como atividade econômica, tem atraído a atenção de diversos estudos acadêmicos (DOBSON e GODDARD, 2001; SOUZA, 2004 e MADALOZZO, 2008). Entre os resultados obtidos nesses estudos, tem-se divergências com relação à variável preço nas equações de demanda por futebol. Dessa forma, este estudo objetiva identificar a relação entre preço e demanda por futebol. Foram utilizados dados secundários a partir do IBGE, da CBF e da Pluri Consultoria. A pesquisa faz uma análise a partir de 380 jogos do campeonato brasileiro. Para estimação da demanda utilizou-se o método de MQO. O modelo teve como variável dependente o público pagante presente nos estádios. Os resultados evidenciaram que a função demanda é não homogênea.

Resumo A doença de Moyamoya é uma grave enfermidade crônica, caracterizada por oclusão das grandes artérias na base do cérebro e é considerada importante causa de acidente vascular cerebral. O objetivo deste estudo consistiu em investigar a experiência e os sentimentos de mães diante do diagnóstico e da evolução da doença de Moyamoya e de seu tratamento em seus filhos. Trata-se de uma pesquisa descritiva, com análises quantitativa e qualitativa. Participaram do estudo oito mães de filhos com diagnósticos da doença de Moyamoya provenientes de três estados da região Sudeste do Brasil. Os dados foram coletados por meio de questionários via página da Internet. Os resultados mostram que o processo de diagnóstico da doença foi vivido com temores e tristeza, agravados pelas dificuldades diagnósticas e escassez de informações. As mães relataram desespero, medo, dificuldade de aceitação, culpa e temor na realização de angiografia cerebral e cirurgia. A fé e a espiritualidade foram referidas como fontes de apoio e de manutenção da esperança. Assinala-se a necessidade de estudos que colaborem para maior esclarecimento sobre a doença e a vivência de doentes e familiares.

Published: November 2017

ABSTRACT: This study has aimed to evaluate the effect of prohexadione-calcium as a plant growth regulator on growth and quality of Japanese lawn grass, Broadleaf carpet grass and Bermudagrass. The treatments and doses of the prohexadione-calcium tested with two three reapplications were 27.5, 55.0, 110.0, 165.0 and 165.0 g a.i. ha-1, and a control without application of a growth regulator. Visual injury evaluations were performed using a scale of scores and plant height and chipping dry matter were determined. We have evaluated the total thickness of the sod grass, root length and dry matter of this material at the end of the experimental period. The study was arranged in a completely randomized design with four replications. The results were submitted to analysis of variance by F-test and the averages of the treatments were compared by t test at 5% probability. The prohexadione-calcium plant growth regulator was visually selective and reduced shoot growth of the three species of grass and can thus be used in the management of lawns in gardens and sports areas. As for the production of sod grass, the prohexadione-calcium can be recommended for Japanese lawn grass and Broadleaf sod grass, especially doses 165.0+165.0 and 55.0+55.0+55.0 respectively, because they have provided a better quality sod grass. For Bermudagrass, the effect of the treatments was harmful for the quality of sod grass and is not recommended for production purposes.

Published: November 2017

ABSTRACT: The objective of this study was to evaluate the chemical control of the species C. benghalensis and C. erecta with desiccants alone and mixtures, as well as the spreading of spray droplets on the leaf surfaces. The experimental design was completely randomized in a 2 x 16 factorial arrangement with four replications, totaling 32 treatments and 128 plots. The first factor is related to the species C. benghalensis and C. erecta and the second factor corresponds to the treatments carfentrazone-ethyl in doses of 15, 30, 60 g ha-1, which added 0.5% v v-1 adhesive spreader; glufosinate ammonium at doses of 100, 200, 400 g ha-1, added 0.5% v v-1 mineral oil; glyphosate at 240, 480, 960 g ha-1; carfentrazone-ethyl + glufosinate ammonium in doses of 100, 200, 400 g ha-1 being added 0.5% v v-1 of mineral oil; carfentrazone-ethyl + glufosinate ammonium in doses of 15+100, 30+200, 60+400 g ha-1 being added 0.5% v v-1 of mineral oil; and carfentrazone-ethyl + glyphosate at 15+240, 30+480, 60+960 g ha-1, which added 0.5% v v-1 of a spreader and sticker agent, besides the controls without applications. There was a difference in control between species for desiccants applied alone. For C. benghalensis there was an excellent control (> 85%) for all the treatments. However, for C. erecta the best controls involved glufosinate ammonium (200 and 400 g ha-1), carfentrazone-ethyl (30 and 60 g ha-1), glyphosate (960 g ha-1) and all mixtures with an average of 96.6% in the control.

ABSTRACT: Castorbean presents high sensitivity to competition; therefore, it is necessary to develop alternatives for the weed management, mainly for the chemical control of eudicotyledons species. The goal of this work was to evaluate the selectivity of chlorimuron-ethyl to castorbean crops in different development stages. Four experiments differentiated by the genetic material were conducted: Lyra, Íris and Savana hybrids and AL Guarany 2002 cultivar. The treatments corresponded to the application conditions of chlorimuron-ethyl [sample control with no application, doses of 15 e 20 g a.i. ha-1 with the formulations Classic™ and Clorimuron Master Nortox™] in two phenological crop stages (4 to 5 and 7 to 8 true leaf stages). The experimental design was in randomized blocks with four replications, in a factorial scheme of 5 x 2 (herbicide and application stage). The intoxication was more severe for the 7 to 8 leaf stage and with the dose of 20 g ha-1 on day 7 days after application (DAA); there were plant recovery and mild symptoms on day 21 DAA, especially for the 4 to 5 leaf stage. The yield was reduced with the 20 g ha-1 dose for Lyra hybrid with both formulations and for Savana castorbean, only with the Classic™ formulation. The chlorimuron-ethyl herbicide, at 15 g ha-1, showed selectivity to castorbean, regardless of the stage application (4 to 5 or 7 to 8 leaves).
