Synthesis and Photoelectrochemical Activity of TiO2 Nanotube Based Free Standing Membrane
Authors: Misriyani  , Kunarti E.S.
Published: October 2020

TiO2 nanotubes (TNTs) were synthesized and modified using the anodization method in a glycerol and ammonium fluoride solution, which was followed by a thermal treatment. The second anodisation was continued by increasing anodizing voltage to deposit a film on the surface of titanium, which resulted in a free standing membrane based on of TNTs. The nanotubes were further characterised using X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared (FTIR) spectroscopy. The SEM result showed that the layer thickness of free standing membrane based on TNTs increased with an increase in the anodizing voltage; however, at high voltages, this layer was damaged. The XRD and FTIR results indicated the generation of TNT having an anatase crystal phase. The results of test for photoelectrochemical properties showed that the optimal conditions of anodizing voltage was 50 V maintained for 1 h.

Published: October 2020

A new series of organotin(IV) and organosilicon(IV) complexes were synthesized using the Schiff base ligands [2-((3,4-dimethoxybenzylidene)amino)-3-(1H-indol-3-yl)propanoic acid (L1H) and 2-((3,4-dimethoxybenzylidene)amino)-3-methylbutanoic acid (L2H)]. The synthesized compounds were characterized by IR, NMR (1H and13C), elemental analysis and theoretical studies. The molar conductivity values of the complexes in DMF implied the presence of non-electrolyte species. Spectral data showed that in these complexes the metal atoms are coordinated with the Schiff base ligand acts as a bidentate ON moiety, coordinating to the metal through its carboxylate oxygen and imine nitrogen. The IR spectra of the complexes showed large differences between νasy(COO) and νsy(COO), Δν (νasy(COO)–νsy(COO)) of 260-276 cm–1, indicating monodentate nature of the carboxylate group. Furthermore, the density functional theory (DFT) calculations were executed at the B3LYP/6-31G(d,p)/ LanL2DZ basis set of theory for the optimized geometry of Schiff base complexes. The structural parameters, bond length, bond angles, chemical potential, electronegativity, hardness, softness, global electrophilicity index have been studied theoretically by density functional theory (DFT) to support the experimental results.

Published: October 2020

Analysis of arson debris is the foremost challenging task to the forensic investigators. Identification of the ignitable liquid residues in the fire debris is one of the prime objectives of forensic quest. This study evaluates the potential of derivative ultraviolet-visible spectrophotometric methods for the analysis and identification of ignitable liquid residues. In this work, arson was simulated using kerosene as an ignitable liquid on various matrices. Derivative UV spectra of kerosene were recorded in their neat state and compared with those obtained from simulated fire debris samples for the identification and detection of ignitable liquid residues. It was observed that different burnt substrates did not cause any interference. The obtained results indicated that the ignitable liquid absorption capacity of the substrate can play an important role in the extraction and identification of ignitable liquid from fire debris. The used technique proved to be rapid, easy, reproducible and efficient.
Identifying aspects of temporal orientation in students’ moral reflections
Authors: Ammert Niklas , Sharp Heather , Löfström Jan , Edling Silvia
Published: October 2020

History education comprises moral issues and moral aspects, often perceived as an important and meaning-making foundation that makes learning relevant and interesting. The interrelationship between time layers fuels historical interpretations and facilitates perceptions of moral issues. This article focuses on a study investigating how secondary school students express inter-temporal relationships in encounters with a morally challenging historical event, which for the participants would have been a moral dilemma. Using historical consciousness as the theoretical framework, a matrix linking two prominent theoretical models – Jörn Rüsen’s (2004) types of narratives and Ann Chinnery’s (2013) strands of historical consciousness – was developed to analyse and categorize secondary school students’ expressions of temporal orientation. To carry out the research, 15-year-old Finnish and Swedish students read an excerpt from Christopher Browning’s (2017) bookOrdinary Men: Reserve Police Battalion 101 and the Final Solution in Poland(originally published in 1992). The students answered and discussed open-ended questions regarding the relevance of the text to their lives and others’ lives, and the applicability of this historical situation to Europe now and in the future. Using this empirical material, the analysis provides a tentative overarching depiction of students’ expressions of temporal orientation, and reports on findings of how temporal orientations relate to moral reflection.
Historical experiences: A framework for encountering complex historical sources
Authors: Zachrich Lisa , Weller Allison , Baron Christine , Bertram Christiane
Published: October 2020

We encounter information about the past in everyday life through films, books and complex historical sources – such as historic sites or eyewitness accounts. Investigations of how visitors and learners engage with these complex historical sources have mainly focused on the ‘something special’ of the encounter on the one hand and on the clear cognitive engagement on the other. Yet, we know little about what and how learners and visitors learn from these complex historical sources and the resultant historical experiences. However, it is an important precondition for further theoretical and empirical research to fully understand these experiences. This article takes the first step in building an integrated model to understand from a situated embodied perspective thehistorical experiencesderived from encounters with complex historical sources. Drawing on German- and English-language literature across related disciplines, we conceptualized the experience within an interplay of cognitive, affective and physical engagement. Within these dimensions, we identified responses that indicate the different elements of the historical experience and discuss limitations and avenues for further research.
Integrated framework for enhancing earthquake risk mitigationn decisions

Published: October 2020

The increasing scale of losses from earthquake disasters has reinforced the need for property owners to become proactive in seismic risk reduction programs. However, despite advancement in seismic design methods and legislative frameworks, building owners are found unwilling or lack motivation to adopt adequate mitigation measures that will reduce their vulnerability to earthquake disasters. Various theories and empirical findings have been used to explain the adoption of protective behaviours including seismic mitigation decisions, but their application has been inadequate to enhance building owners’ protective decisions. A holistic framework that incorporates the motivational orientations of decision-making, coupled with the social, cultural, economic, regulatory, institutional and political realms of earthquake risk mitigation to enhance building owners’ decisions to voluntarily implement adequate mitigation measures, is proposed. This framework attempts to address any multi-disciplinary barriers that exist in earthquake disaster management, by ensuring that stakeholders involved in seismic mitigation decisions work together to foster seismic rehabilitation of EPBs, as well as illuminate strategies that will initiate, promote and sustain the adoption of long-term earthquake mitigation.

Cuckoo index

Published: October 2020

In modern data warehousing, data skipping is essential for high query performance. While index structures such as B-trees or hash tables allow for precise pruning, their large storage requirements make them impractical for indexing secondary columns. Therefore, many systems rely on approximate indexes such as min/max sketches (ZoneMaps) or Bloom filters for cost-effective data pruning. For example, Google PowerDrill skips more than 90% of data on average using such indexes.

In this paper, we introduce Cuckoo Index (CI), an approximate secondary index structure that represents the many-to-many relationship between keys and data partitions in a highly space-efficient way. At its core, CI associates variable-sized fingerprints in a Cuckoo filter with compressed bitmaps indicating qualifying partitions. With our approach, we target equality predicates in a read-only (immutable) setting and optimize for space efficiency under the premise of practical build and lookup performance.

In contrast to per-partition (Bloom) filters, CI produces correct results for lookups with keys that occur in the data. CI allows to control the ratio of false positive partitions for lookups with non-occurring keys. Our experiments with real-world and synthetic data show that CI consumes significantly less space than per-partition filters for the same pruning power for low-to-medium cardinality columns. For high cardinality columns, CI is on par with its baselines.
Synergetic Effect of Multi-Dimensional Nanomaterials on Aging Resistance of Asphalt
Authors: Zhang Henglong , Zhu Chongzheng , Duan Haihui
Published: October 2020

The effect of different nanomaterials on the aging resistance of asphalt was investigated. Three types of nanomaterials, organic expanded vermiculite (OEVMT), nano zinc oxide (ZnO), and multi-dimensional nanomaterials composed by OEVMT and ZnO, were compared. The results show that the single nanomaterial (OEVMT or ZnO) can only enhance one of the abilities to resist thermal-oxidative aging and ultraviolet aging, whereas the multi-dimensional nanomaterials can improve both types of aging resistance effectively. Moreover, compared with the single nanomaterials, the multi-dimensional nanomaterials under the same content show an excellent synergetic effect on thermal-oxidative antiaging ability and have the equivalent ultraviolet aging resistance.

Published: October 2020

HIV risk perception is a known determinant of HIV prevention behaviors among vulnerable populations. Lesser known is the combined influence of risk perception and efficacy beliefs on PrEP use. We examined the associations between levels of risk perception and strength of efficacy beliefs on intent to use PrEP in a sample of adult Black and Latina women. Guided by the risk perception attitudes (RPA) framework, we used cluster analysis to identify four interpretable groups. We ran analysis of covariance models to determine the relationship between membership in the RPA framework groups and intention to use PrEP. Among the 908 women, the mean age was 29.9 years and participants were Latina (69.4%) and Black (25.6%). Results of the analysis show that women with low perception of HIV risk and strong efficacy beliefs had significantly less intent to use PrEP than women with high risk perception and weak efficacy beliefs.

Authors: Risteski Petar , Radwan Medhat , Boshkoski Gjoko , Salem Razan , Iavazzo Annarita , Walther Thomas , Esposito Giampiero
Published: October 2020

Background: Reports of minimal invasive aortic arch surgery are scarce. We reviewed our experience with minimal access aortic arch surgery performed through an upper mini-sternotomy, with emphasis on details of operative technique and early and mid-term outcomes.
Methods: The medical records of 123 adult patients (mean age 66 ± 12 years), who underwent primary elective minimal access aortic arch surgery in two aortic referral centers, were reviewed. The most common indication was degenerative aortic arch aneurysm in 92 (75%) patients. Standard operative and organ protection techniques used in all patients were upper mini-sternotomy, uninterrupted antegrade cerebral perfusion, and moderate systemic hypothermia (27.4 ± 1°C).
Results: Sixty-eight (55%) patients received partial aortic arch replacement; the remaining 55 (45%) patients received total arch replacement, further extended with either a frozen elephant trunk in 43 (35%) patients or a conventional elephant trunk procedure in nine (7%) patients. No conversion to full sternotomy was required. New permanent renal failure occurred in one (0.8%) patient, stroke in two (1.6%), and spinal cord injury in four (3.3%) patients. Early mortality was observed in four (3.3%) patients. At five years, survival was 80 ± 6% and freedom from reoperation was 96 ± 3%.
Conclusion: Minimal invasive aortic arch repair through an upper mini-sternotomy can be safely performed, with early and mid-term outcomes well comparable to series performed through a standard median sternotomy.

Population Based Birth Prevalence of Disease-Specific Perinatal Stroke
Authors: Dunbar Mary , Mineyko Aleksandra , Hill Michael , Hodge Jacquie , Floer Amalia , Kirton Adam
Published: October 2020

BACKGROUND:

Perinatal stroke encompasses multiple disease-specific cerebrovascular syndromes that cause lifelong neurodevelopmental morbidity for millions worldwide. Acute presentations include neonatal arterial ischemic stroke (NAIS), neonatal cerebral sinovenous thrombosis, and neonatal hemorrhagic stroke (NHS). Delayed presentations include arterial presumed perinatal ischemic stroke, periventricular venous infarction, and presumed perinatal hemorrhagic stroke. Our objective was to define the birth prevalence of all subtypes of perinatal stroke by using a population-based cohort.

METHODS:

The Alberta Perinatal Stroke Project is a research cohort established in 2008 in southern Alberta, Canada, with prospective (2008–2017) and retrospective (1990–2008) enrollment leveraging universal health care at a single tertiary care pediatric center. The primary outcome was the estimated birth prevalence of each perinatal stroke syndrome, secondary outcomes were birth prevalence over time, sex ratios, and change in age at diagnosis. Analysis included Poisson regression, Wilcoxon rank test, and Fisher exact test.

RESULTS:

The overall estimated birth prevalence of term-born perinatal stroke was 1:1100. The estimated birth prevalence was 1:3000 for NAIS, 1:7900 for arterial presumed perinatal ischemic stroke, 1:6000 for periventricular venous infarction, 1:9100 for cerebral sinovenous thrombosis, 1:6800 for NHS, and 1:65000 for presumed perinatal hemorrhagic stroke. The apparent birth prevalence of NAIS and NHS increased over time. There were more males affected than females. The age at diagnosis decreased for late-presenting stroke types.

CONCLUSIONS:

The estimated birth prevalence of term perinatal stroke is higher than previous estimates, which may be explained by population-based sampling of disease-specific states. This emphasizes the need for further studies to better understand the disease-specific pathophysiology to improve treatment and prevention strategies.

WATER EROSION IN EUCALYPTUS FOREST IN THE MUNICIPALITY OF OTACÍLIO COSTA (SC)
Authors: Pereira Gilmar Souza , Bertol Ildegardis , Magro Bruno Afonso , Andreola Ariane , Bagio Bárbara
Published: October 2020

ABSTRACT Water erosion is the main factor of degradation and reduction of the productive capacity of the soil, requiring management operations that minimize water and soil losses and at the same time maximize crop productivity. The research aimed to quantify losses by water erosion and, in the runoff water, determine the levels and total losses of P and K during the development of Eucalyptus (Eucalyptus benthamii). Eucalyptus was planted in three types of soil preparation: minimum preparation in the direction of the slope, minimum preparation in the contour of the slope, and semi-mechanized preparation, in an experiment in southern Brazil on a Haplic Dystrudept soil. We observed that the mechanical preparation of the soil carried out in the direction of the slope is less effective in controlling soil losses than the mechanical carried out perpendicularly to the slope and also less effective than the manual in pits, in which the soil losses are equivalent to 10% of those that occur in the direction of the slope. As for the control of water losses, manual preparation in pits is more effective than the two mechanized preparations. The greatest losses of soil occur in the fall, with losses 27 times greater in relation to the other seasons of the year, and the greatest losses of water occurred in the mechanized preparation perpendicular to the slope and in the manual preparation. Water losses vary less than soil losses, regardless of the type of soil preparation and the season. The losses of phosphorus and potassium by the Runoff water vary with the contents in the soil, with the type of soil preparation and with the moment of evaluation.
MACRONUTRIENT DEFICIENCY IN CARINIANA ESTRELLENSIS (Raddi) KUNTZE: FROM CHANGES IN CELL ULTRASTRUCTURE TO VISUAL SYMPTOMS
Authors: Andrade Marcelo Leandro Feitosa de , Boaretto Antonio Enedi
Published: October 2020

ABSTRACT The nutritional requirements of native forest species can influence productivity. Thus, the understanding of these requirements enables us to optimize the use of inputs and reduce the environmental impacts inforest restoration projects. The present study aimed to evaluate changes in cellular ultrastructure and the anatomy of leaf laminae as well as observe visual signs of nutrient deficiency in young Cariniana estrellensis (Raddi) Kuntze plants, a forest species widely used in ecological restoration projects. The experiment was conducted in a greenhouse in random blocks with three replications of seven treatments using nutrient subtraction (I.e., control [plants grown with all nutrients], -N, -P, -K, -Ca, -Mg, and -S). The plants were harvested 135 days after the beginning of the treatments when the deficiency of the macronutrients resulted in visible abnormalities. Changes in the cell ultrastructure and structure of the chloroplasts, cytoplasm, and stromal lamellae were observed, as well as starch and lipid concentrations in the cytoplasm, intercellular spaces, and parenchymal cells. Changes in the cell ultrastructures, leaf laminae, and visual signs of nutrient deficiency hindered the development of young C. estrellensis plants; therefore, forest restoration projects that use this species in soils that require nutritional supplementation may have limited success in the absence of nutritional support.

Published: October 2020

ABSTRACT Over the last decade, conilon coffee (Coffea canephora) in consortium with wood trees has been established to improve environmental conditions. Little is known about how individual wood trees and banana affect soil quality when intercropped with conilon coffee. The objective of the present study was to evaluate the impacts of intercropping organic conilon coffee with different wood tree species and banana on C balance. Five cultivation systems including conilon coffee monoculture and intercropped with Inga edulis, Gliricidia sepium, BRS Japira banana (Musa sp.), or Bactris gasipaes were studied in a randomized complete block design, with four replicates at the south of Espírito Santo State, Brazil. A primary forest fragment adjacent to the experiment was also evaluated for comparison with the consortium. Samples of topsoil (0 to 10 cm) were collected in 2016 to evaluate the total organic C and total N. Soil temperature and moisture at 0 to 5 cm depth and the CO2 emission were measured monthly over one year. The species planted with the conilon coffee promoted a 5.52% decrease in the soil temperature and a 17% increase in the soil moisture content. They also promoted an increase in annual C balance, especially intercropped with Gliricidia and Inga (4.70 and 3.56 Mg ha-1, respectively), with a substantial increase in the soil total organic C and total N in both systems.

Metodologia alternativa de medida da densidade de meios porosos em laboratórios didáticos de física
Authors: Camargo Mario A. , Pires Luiz F. , Brinatti André M. , Saab Sérgio C.
Published: October 2020

Quando se estuda a qualidade física de meios porosos como o solo uma propriedade de bastante relevância é a sua densidade, ρs. As medidas de ρs são importantes devido à influência desta propriedade em outras deste sistema poroso (e.g., porosidade, umidade volumétrica, armazenamento de água, etc). Neste trabalho propõe-se uma metodologia alternativa para a medida de ρs, chamada de método da sela a vácuo. A impermeabilização da amostra, contrário aos métodos tradicionais como torrão parafinado, é feita utilizando embalagem plástica com posterior evacuação do ar interno usando bomba de vácuo. Medidas de ρs pelo método do torrão parafinado foram utilizadas como referência. Os resultados obtidos mostram que em relação ao método do torrão parafinado, ρs medido pelo método da sela a vácuo é, em média, subestimado para todos os diferentes tipos de solos analisados. O método proposto é mais rápido e apresenta maior confiabilidade na impermeabilização que o método tradicional, além disso, permite reutilizar a amostra para novas medidas. O novo método ainda pode ser facilmente implementado em laboratórios de ensino de física para o ensino médio e para o ensino superior nos cursos de bacharelado, engenharias e agronomia. Por se tratar de um método que envolve pouco manuseio, rápido e de fácil implementação, torna-se ideal para o estudo não somente de ρs, mas também de conceitos envolvidos em sua medida como massa, volume, massa específica, peso, peso aparente e empuxo.

Anthropology and the State in Brazil: questions concerning a complex relationship
Authors: Lima Antonio Carlos de Souza , Dias Caio Gonçalves
Published: October 2020

Abstract In this article we argue that, in order to understand the “attack” made on anthropology in Brazil, undertaken in the public sphere since the beginning of the second decade of the twenty-first century, we need to look at how anthropological knowledge has become disciplined and institutionalized in the medium to long term. We refer, in particular, to the relationship between what has been constituted as a “field of anthropology” and issues related to the public sphere. It is also necessary to consider the configuration with other institutionalized knowledge throughout the period spanning from the end of the nineteenth century to the present, with discontinuities but also with some important continuities. We look to show that the anthropology initially undertaken in Brazil was basically committed to furthering the interests of the agrarian-based political elites, a situation that continued from the turn of the nineteenth century to the twentieth century and into the first decades of the twenty-first, not only at the level of nation building, but also in the formation of the State. However, since the 1950s, and especially following creation of the new postgraduate courses in the late 1960s and early 1970s, anthropologists developed knowledge that led them to make an ethical and moral commitment to the communities with which they worked, combined with a critique of the military regime’s developmentalism and dictatorial authoritarianism. During a third moment ranging from the constituent process to the present, a portion of Brazilian anthropologists began to work directly in the recognition of rights constitutionally assigned to differentiated collectivities, generating a growing and progressive zone of friction with the hegemonic sectors at the economic-political level.
A QUALIDADE DA EDUCAÇÃO NO HORIZONTE DA PROTEÇÃO INTEGRAL INFANTO-ADOLESCENTE
Authors: Nascimento José Almir do , Cury Carlos Roberto Jamil
Published: October 2020

Resumo O artigo pretende problematizar o conceito de qualidade da educação vislumbrado no Estatuto da Criança e do Adolescente (ECA), construído no lastro das lutas por direitos humanos infanto-adolescentes. Esse conceito se impõe como uma ampliação do espectro dos direitos da cidadania e dos direitos sociais dos educandos, de modo que o conteúdo do direito à educação não pode ser considerado ideologicamente neutro. O estudo qualitativo de tipo bibliográfico examina no acervo doutrinário e normativo os fundamentos da qualidade educacional como direito humano, tendo-a como horizonte de proteção integral das infâncias. Notamos que a qualidade preconizada como proteção integral não é um fato, nem um ato que depende com exclusividade do texto positivado. Ela depende, além dos fatores econômicos, de condições políticas, engajamento da família e da sociedade, nível de democracia e estruturas de Estado para assegurar sua efetividade.
EDUCAÇÃO E DEMOCRACIA: DO RISCO DE DESARTICULAÇÃO A UMA RECOMPOSIÇÃO CRÍTICA
Authors: Barbosa Manuel Gonçalves
Published: October 2020

Resumo Retornando a um tema que é um clássico em teoria da educação, o presente artigo procura respostas fundamentadas para um problema atual: a erosão da relação entre educação e democracia e o risco de assistirmos, se nada for feito, a uma desarticulação de ambas nos contextos em que a neoliberalização levou mais longe a economização de esferas e atividades, incluindo as não diretamente económicas. Voltado para as instituições escolares, e partindo da análise criteriosa desse fenómeno, o artigo aponta para uma recomposição crítica do alinhamento entre educação e democracia, especificando o que isso implica no percurso educativo dos mais novos nas escolas realmente existentes.

RESUMO: O artigo discute o processo de introdução de argumentos adicionais à estrutura básica do verbo na língua Karitiana (língua da família Tupi, subfamília Arikém, localizada em Rondônia, com uma população de 396 indivíduos e 333 falantes). Adota-se, para análise e discussão dos dados, duas propostas teóricas (i) a teoria de estrutura argumental de Hale e Keyser (2002) e (ii) a proposta teórica de núcleos aplicativos de Pylkkänen (2008). Na proposta teórica (i), Karitiana apresenta quatro tipos de verbos (1 - intransitivo, 2 - intransitivo com objeto oblíquo, 3 - transitivo e 4 - bitransitivo), já na segunda proposta, por sua vez, mais econômica, a língua é analisada como tendo apenas dois tipos verbais (1 - intransitivo e 2 - transitivo). Nesta última, o sistema verbal Karitiana apresenta duas estruturas básicas em que argumentos extras são incrementados por meio de núcleos aplicativos e Voice. Este adiciona argumentos altos na estrutura em estruturas causativas. Os aplicativos são de dois tipos, isto é, o alto que insere um argumento extra acima do VP e o baixo que adiciona argumentos extras abaixo ou internamente ao VP.
A LINGUÍSTICA EM MANUAIS BRASILEIRO E SOVIÉTICO
Authors: Grillo Sheila Vieira de Camargo
Published: October 2020

RESUMO: O objetivo deste artigo é apresentar os resultados de uma pesquisa em análise comparativa de manuais de introdução à linguística brasileiro e soviético do final dos anos 1960 e início dos anos 1970. A delimitação do material de comparação foi empreendida por meio do procedimento metodológico denominado tertium comparationis, tal como ele foi desenvolvido pelos pesquisadores do Clesthia – axe sens et discours. A análise dos manuais foi orientada pelos conceitos e procedimentos elaborados por Bakhtin e o Círculo. Concluímos que a história da ciência nas duas línguas/culturas, o diálogo com a linguística desenvolvida em países com maior tradição na área e o meio social mais amplo foram fatores que fixaram limites, exerceram pressões e direcionaram sentidos para as apresentações da linguística aos futuros integrantes dessa ciência. A interação desses três processos sociohistóricos são fundamentais na definição das escolas linguísticas, na delimitação do objeto da linguística e na avaliação dos seus métodos.

Resumo O artigo sintetiza um estudo que visou demonstrar as bases legais e socioeconômicas do surgimento do direito universal à saúde na URSS. Utilizando pesquisa bibliográfica, são analisados três trabalhos que apresentam cenários sobre a criação e implantação do sistema de saúde soviético, escritos entre 1933 e 1937. Para a análise dos trabalhos, utilizou-se materialismo histórico dialético, baseado em Marx e Engels, utilizando as categorias de forças produtivas, relações de produção, revolução social e política, mercadorias e salários. Identificaram-se, na análise dos trabalhos, evidências materiais que apontam o surgimento do direito universal à saúde no contexto revolucionário, concluindo que a saúde livre e universal, como nova qualidade de serviço voltado ao atendimento das necessidades de reprodução social foi consequência da transição entre modos de produção, observada na revolução russa.

Published: October 2020

Resumo Prática Baseada em Evidências é uma abordagem que tem apresentado notoriedade para melhorar a efetividade clínica e apoiar o profissional de saúde nas suas condutas, utilizando três elementos: evidências científicas, a experiência clínica e as preferências do paciente. O objetivo do estudo é conhecer como se desenvolve a Prática Baseada em Evidências na Atenção Primária à Saúde, especificamente, na Estratégia Saúde da Família, bem como propor a inclusão do elemento “análise sociocultural” para a tomada de decisão. Estudo qualitativo, precedido da realização de dois grupos focais, com a participação de 14 profissionais de saúde. A técnica de análise de conteúdo temática foi utilizada para avaliação, tratamento e interpretação das informações. Os profissionais da Estratégia Saúde da Família têm dificuldade para desenvolver uma prática em saúde voltada a evidências científicas, apontando carência de conhecimentos e habilidades para a pesquisa e elevada carga de trabalho. Ademais, os resultados indicam que a Prática Baseada em Evidências deve ser diferenciada segundo a realidade dos territórios de atuação das equipes. Cabe aos profissionais de saúde identificar e valorar as características socioculturais da comunidade para uma Prática Baseada em Evidências mais sensível às necessidades de saúde de sua população adscrita.
The heritage and refurbishment of grade II listed piers at Whitby harbour, North Yorkshire

Published: October 2020

The £6.76 million refurbishment of Whitby's famous west and east piers improved the condition of the grade II listed structures into the foreseeable future. The project stabilised sandstone facing blocks, filled voids and repaired the deck surface to prevent damage from water ingress. A new flood deflector wall at the adjoining slipway was built in preference to a more visually intrusive flood gate alternative, and this wall now lessens the impact of wave run-up on the slipway during stormy sea conditions, protecting several commercial properties against sea flooding, which previously regularly occurred. The construction work, susceptible to unpredictable weather and undertaken in a hostile marine environment, was carried out from marine craft, using cranes with suspended access systems and divers, all working in tidal conditions. Through careful planning and coordination, construction was completed safely, ahead of programme and £150 000 under budget. This paper describes the physical setting and historic development of the harbour at Whitby, draws lessons from an earlier refurbishment of another grade II listed marine structure and demonstrates how these lessons were applied to the refurbishment of the Whitby harbour piers to ensure that the works remained sympathetic to the heritage values and iconic aesthetic setting of the area.

Published: October 2020

Bu araştırmanın amacı erken çocukluk eğitimi öğretmenlerinin Türkçe etkinliklerinde kullandıkları ve tercih ettikleri kitap okuma/hikâye anlatma tekniklerini belirlemek ve bu tekniklerin tercih nedenlerini incelemektir. Temel nitel araştırma deseninin kullanıldığı bu araştırmaya erken çocukluk eğitim kurumlarında çalışmakta olan 91 okul öncesi öğretmeni katılmıştır. Veriler sıralama yargılarına dayalı olarak geliştirilen ‘Hikâye anlatma ve kitap okuma formu’ aracılığıyla toplanmış ve içerik analizi kullanılarak analiz edilmiştir. Araştırma bulguları öğretmenlerin sınıflarında en fazla geleneksel okumayı, en az dijital okumayı uyguladıklarını, çocukların en fazla dijital okumayı tercih ettiklerini ve etkileşimli okumanın ise en fazla öğrenmeyi destekleyen teknik olduğunu ortaya koymuştur. Hikâye anlatma teknikleri ile ilgili bulgular ise öğretmenlerin ve çocukların kuklalarla anlatımı daha çok tercih ettiklerini ancak yine de öğretmenlerin sınıf uygulamalarında en sık sesli (araçsız) anlatıma yer verdiğini göstermiştir. Öğretmenlerin tercihlerini tekniklerin hızlı, kolay, ekonomik olması ve çok fazla ön hazırlık gerektirmemesi gibi nedenlerin etkilediği belirlenmiştir.
