Authors: Memarian Azadeh , Sanatkaran Afsaneh , Bahari Seyyed Mohialdin
Published: July 2017

Background: The aim of the present study is to evaluate the effects of laughter yoga exercises on anxiety and sleep quality in patients suffering from Parkinson’s disease. Methods: In the study a semi-empirical and applied research design was used, which involved a pre-test and post-test, and appropriate control group. The study consisted of 24 patients suffering from Parkinson’s disease who were referred and admitted to Hazarate Raoul Allah Hospital in Tehran, Iran. The patients ranged in age from 55 to 75 and met the study criteria prior to entering the research study. The patients were randomly divided into two groups – control or experimental (n=12 per group). After completing exercises (laughter yoga), post-evaluation of anxiety and sleep quality of patients in both groups were conducted using questionnaires. For normalization of research data, the Mann-Whitney nonparametric test was used. Statistical analyses were conducted using the SPSS software, with the statistically significant level set at P<0.05. Results: The Mann-Whitney tests indicated that there was a significant difference between the  average stress change as well as sleep quality in patients suffering from Parkinson’s disease (versus control subjects) following laughter yoga exercises. Indeed, regarding sleep quality laughter yoga was only effective on the subjective quality of sleep and latency in sleeping. There was no observation of a significant effect on the duration of sleep, sleep efficiency, sleep disturbances, use of sleeping pills, or daily functions of the patients. Conclusion: The results of the present study demonstrate that laughter yoga exercises can reduce anxiety and improve sleep quality in patients suffering from Parkinson’s disease. As a result, laughter yoga exercises may be beneficial as a complementary therapy with standard treatment methods to reduce anxiety and improve sleep quality in patients with Parkinson's.
Variation in Preoperative Testing and Antireflux Surgery in Infants
Authors: Short Heather L. , Braykov Nikolay P. , Bost James E. , Raval Mehul V.
Published: July 2017

BACKGROUND:

Despite the availability of objective tests, gastroesophageal reflux disease (GERD) diagnosis and management in infants remains controversial and highly variable. Our purpose was to characterize national variation in diagnostic testing and surgical utilization for infants with GERD.

METHODS:

Using the Pediatric Health Information System, we identified infants <1 year old diagnosed with GERD between January 2011 and March 2015. Outcomes included progression to antireflux surgery (ARS) and use of relevant diagnostic testing. By using adjusted generalized linear mixed models, we compared facility-level ARS utilization.

RESULTS:

Of 5 299 943 infants, 149 190 had GERD (2.9%), and 4518 (3.0%) of those patients underwent ARS. Although annual rates of GERD and ARS decreased, there was a wide range of GERD diagnoses (1.8%–6.2%) and utilization of ARS (0.2%–11.2%). Facilities varied in the use of laparoscopic versus open ARS (mean: 66%, range: 23%–97%). Variation in facility-level ARS rates persisted after adjustment. Overall 3.8% of patients underwent diagnostic testing, whereas 22.8% of ARS patients underwent diagnostic testing. The proportion of surgeries done laparoscopically was independently associated with ARS utilization (odds ratio: 1.57; 95% confidence interval: 1.21–2.02). Facility-level utilization of diagnostics (P > .1) and prevalence of GERD (P > .1) were not associated with utilization of ARS.

CONCLUSIONS:

There is notable variation in the overall utilization of ARS and in the surgical and diagnostic approach in infants with GERD. Fewer than 4% of infants with GERD undergo diagnostic testing. This variation in care merits development of consensus guidelines and further research.

Discrete particle translation gradient concept to expose strain localisation in sheared granular materials using 3D experimental kinematic measurements
Authors: Druckrey A. M. , Alshibli K. A. , Al-Raoush R. I.
Published: July 2017

It is well known that the constitutive behaviour of granular materials is influenced by strain localisation into zones of intensive shearing, known as shear bands. The failure mode of specimens tested under axisymmetric triaxial compression is commonly manifested through single or multiple shear bands, or diffuse bifurcation (bulging). The ability to monitor and detect the evolution of strain localisation has been enhanced by measuring particle kinematics using discrete-element methods or three-dimensional imaging techniques such as X-ray computed tomography. However, conventional particle kinematic techniques cannot expose intricate localised shearing during the hardening, before the peak principal stress ratio. This paper presents the concept of particle translation gradient to expose strain localisation in granular materials using experimental measurements of particle translation in three dimensions. Individual silica sand particles were identified and tracked through multiple strains and particles’ translations were calculated. Each particle's neighbouring particles were identified and translation fields for each of the neighbouring particles were calculated. The second-order norms between a particle translation vector and the neighbouring particles’ translation vectors were averaged, resulting in a relative translation value for each particle. The translation gradient concept is effective in uncovering the onset of strain localisation within sheared granular materials.

The influence of foundation stiffness on the behaviour of surface strip foundations on sand
Authors: Lemmen H , Jacobsz S , Kearsley E
Published: July 2017

The objective of this study was to determine whether the contact stress distribution underneath a strip footing on dense cohesionless sand can be predicted as a function of the properties of the footing and that of the underlying sand. Together, the footing and the underlying sand form a foundation system which can be classified in terms of relative stiffness. Centrifuge model tests were conducted on seven aluminium footings of various depths and hence stiffness, and one reinforced concrete footing, during which the qualitative variation in contact stress distribution underneath the footing was captured with the use of Tekscan™ pressure sensors. It was found that, as long as the relative stiffness of the foundation classifies as "stiff", the contact stress distribution underneath the footing is approximately uniform. As the relative foundation stiffness is reduced, the contact stress underneath the footing edge as a percentage of the maximum stress occurring underneath the column, reduces. In the case of a semi-flexible footing tested, zero pressure was measured underneath the footing edge in response to loading of the footing. An expression is presented to allow the contact stress under the edge to be estimated as a function of the relative stiffness of the foundation. This allows the contact stress distribution underneath semi-stiff footings to be estimated. The stiffness of the model reinforced concrete footing tested reduced considerably due to cracking during loading. It is recommended that footings be provided with sufficient stiffness to classify as stiff. A modification of the benchmark value for the minimum relative stiffness classifying as stiff is proposed, based on the results of the centrifuge tests.
Revised regional sediment yield prediction methodology for ungauged catchments in South Africa
Authors: Msadala V , Basson G
Published: July 2017

This paper presents the research on the revision of the regional probabilistic method (Rooseboom et al 1992) for the prediction of catchment sediment yields in South Africa. The determination of sediment yields using probabilistic or empirical methods is suitable for ungauged catchments in the absence of observed data. The prediction of sediment loads is a key component in the quest to deal with reservoir and river sedimentation which is a potential threat to the sustainability of water resources in southern Africa. The revision was necessitated by increased sediment data availability and improved data analysis tools. Ten new sediment yield regions were demarcated in South Africa and Lesotho. Two analytical approaches were developed, namely probabilistic and empirical. The probabilistic approach is applicable in sediment yield Regions 3, 6 and 9. The empirical approach is applicable in sediment yield Regions 1, 2, 4, 5, 7 and 8. The estimation of sediment yields in Region 10 (Lesotho Highlands) needs to be based on direct measurements and locally observed data since no adequate analysis of sediment loads was possible due to limited data. GIS and electronic portable document file (pdf) copies of maps were produced for the retrieval of catchment data.
The application of continuous surface wave testing for settlement analysis with reference to a full-scale load test for a bridge at Pont Melin, Wales, UK
Authors: Heymann G , Rigby-Jones J , Milne C
Published: July 2017

The presence of a significant thickness of soft silts beneath the site of a proposed new road bridge caused concerns over the suitability of shallow foundations. Despite extensive conventional ground investigations, it was not possible to obtain reliable stiffness data, and so a full-scale, fully instrumented load test was undertaken to better determine ground stiffness. The data obtained was used in conjunction with sophisticated numerical analysis to demonstrate that the settlement of shallow foundations would be acceptable. Following completion of the bridge construction, Continuous Surface Wave testing was undertaken and a range of simple non-linear elastic settlement analyses conducted to model the behaviour of the load test. Through these analyses this paper demonstrates the benefit of using continuous surface wave ground stiffness testing in conjunction with simple analysis methods. It underlines the importance of obtaining high-quality stiffness data to accurately predict settlement of shallow foundations.
Effect of the minimum void ratio on the vertical intercept of the steady state line of non-plastic soils
Authors: Torres-Cruz L , Geyer S , Mackechnie P
Published: July 2017

The steady state line (SSL) plays a key role in understanding and modelling the mechanical response of soils. Accordingly, understanding how the SSL correlates to soil index properties is of primary importance. A previous study reported that the vertical location of the SSL (Γ1) in void ratio (e) versus mean effective stress (ρ') space is correlated to the minimum void ratio (emin). However, the correlation only included soils with narrow particle size distributions (PSD) and low fines content (FC). In the current study, published data corresponding to 30 non-plastic soils were re-processed to further explore the applicability of the r1-emincorrelation. The results indicate that the r1-emincorrelation is linear (R2 = 0.85) and valid regardless of the coefficient of uniformity (Cu), FC, and particle shape. The r1-emindataset presented herein was also compared to a previously published dataset, and good agreement was observed. It is proposed that the r1-emjncorrelation can be very useful to understand how the Γ1 of different non-plastic soils compare to one another, and to minimise the extent of triaxial testing required when characterising a soil deposit from an SSL standpoint. Limitations of the r1-emin correlation are also discussed.

Published: July 2017

Transmission of bacteria from inanimate surfaces in healthcare associated environments is an important source of hospital acquired infections. A number of commercially available medical devices promise to fulfill antibacterial activity to reduce environmental contamination. Under usual ambient air conditions of hospital rooms no condensation of humidity is expected on inanimate surfaces. In contrast, current standardized methods for the analysis of antibacterial activity of solid surfaces in general use mostly planktonic bacterial cells which are kept in thin liquid or agarose layers on tested surfaces. Therefore, we developed a touch transfer assay modeling fingerprint transmission to investigate the antibacterial activity of surfaces in a dry state. We suggest the newly developed touch transfer assay as a new additional tool for the assessment of potential antimicrobial surfaces prior utilization in hospital environments.

Published: July 2017

Introduction: Breast cancer has a high prevalence among women. It is known that breast cancer survivors can undergo a several alterations due to the treatment, including sexual dysfunction. Objective: This study aimed to determine the incidence of sexual dysfunction in women after breast cancer surgery, and assess the relationship between sexual dysfunctions and pelvic floor muscles (PFM) contraction, as well to verify if hormone therapy caused long-term occurrence of PFM weakness or sexual dysfunction. Methods: The sample was composed by 26 women with 48.4 ± 6.8 years which using hormone therapy treatment at least six months. Data on sexual dysfunction were collected through the Female Sexual Function Index- FSFI questionnaire and a section composed by demographic information. Furthermore, the PFM contraction was assessed using the PERFECT scale. Results: The results demonstrated a high rate of sexual dysfunction (64.3%) and a weak PFM contraction (2.31±1.3) among the women. In addition, a long-term hormone therapy had a negative association with PFM endurance and with the orgasm and satisfaction domains of the FSFI questionnaire. Conclusion: women using hormone therapy after breast cancer surgery had a high rate of sexual dysfunction and the long-term treatment of hormone treatment can be associated with a worsening of orgasm and sexual satisfaction in these women. Also, the use at long-term of hormone therapy had a negative association with the PFM endurance.
Nodes of resistance to green grabbing: a political ecology
Authors: Weeber Stan
Published: July 2017

Green grabbing is the privatization or appropriation of land for purposes of advancing a “green” economy while excluding local, indigenous people from natural resources. This is a problem of global scale that has arisen mainly during a historical period when free market, neo-liberal policies have dominated the world economy. The academic li-terature on the subject rarely mentions resistance to green grabbing, nor are there many efforts to critically and syste-matically examine the social dynamics of this process. We consider both what works and what fails during the process of opposition, as well as the social psychology of risk taking among both green grabbers and opponents. The paper con-cludes with a way forward proffering the resistance.

The Global Yield Gap Atlas project (GYGA - http://yieldgap.org) has undertaken a yield gap assessment following the protocol recommended by van Ittersum et al. (2013). One part of the activities consists of collecting and processing weather data as an input for crop simulation models in sub-Saharan African countries including Kenya. This publication covers daily weather data for 12 locations in Kenya for the years 1998-2012. The project looked for good quality weather data in areas where crops are pre-dominantly grown. As locations with good public weather data are sparse in Africa, the project developed a method to generate bias corrected weather data from a combination of observed data and other external weather data. The bias corrected weather data consist of daily TRMM rain data and NASA POWER Tmax, Tmin, and Tdew data. These data are corrected based on calibrations with short-term (<10 years) observed weather data. The data can be found via DOI 10.17026/DANS-ZYU-XKHC.
Long-term soil hydrological data of a Pleistocene region in North-East Germany
Authors: Schindler Uwe Georg
Published: July 2017

Long-term soil hydrological studies were carried out at the ZALF Muencheberg Experimental Station. Muencheberg is located in a Pleistocene end moraine landscape in NE Germany about 50 km east of Berlin and 40 km west of the Oder river, the border with Poland. The soils are formed on Pleistocene parent material, classified as Haplic Albeluvisol with a Bt horizon mostly beginning at about 70 cm depth. From 1994-1999 the site was used as arable land managed by different farming systems (integrated, integrated with irrigation, ecological and low input). From 2000 to 2005 the effect of different tillage systems (plough and no till) was investigated. Furthermore, soil water was extracted by use of suction cups for analysing the soil water nitrate concentrations. The data were used for quantifying deep drainage rates and nitrate losses as described in (Schindler and Mueller, 2008 and Schindler et al., 2010). All basic data (soil water content, tension, precipitation, potential evapotranspiration and soil water nitrate concentrations) are accessible via DOI 10.4228/ZALF.1995.282.
Hydraulic properties of horticultural substrates
Authors: Schindler Uwe Georg , Eulenstein Frank
Published: July 2017

One main criterion for evaluating the suitability of horticultural substrates for horticultural applications is their capability to store and transport water. The basic substrate hydraulic variables which provide this information are the water retention curve and the unsaturated hydraulic conductivity function. Substrate shrinkage and water repellency are of similar importance. A set of 36 commercial horticultural substrates was selected and the hydraulic properties (water retention curve, unsaturated hydraulic conductivity function, capillary rise and shrinkage) were measured with the Extended Evaporation Method (EEM). Additionally, the water drop penetration time was determined as a measure of wettability. Here the raw data are presented. Data access under DOI 10.4228/ZALF.2015.278.

Four free-air CO2 enrichment (FACE) experiments were conducted on wheat (Triticum aestivum L. cv. Yecora Rojo) at Maricopa, Arizona, U.S.A. from December, 1992 through May, 1997. The first two were conducted at ample and limited (50% of ample) supplies of water, and second two at ample (350 kg N ha-1) and limited (70 and 15 kg N ha-1) supplies of fertilizer nitrogen. More than 50 scientists participated, and they collected a large and varied set of data on plant, soil, and microclimatic responses to the elevated CO2 and its interactions with the water and N treatments. The dataset has been popular with wheat growth modelers who have utilized the growth, yield, and other data to validate their models, which get used to predict likely future wheat productivity with projected global change. The dataset assembled herein contains many of these data, including management, soils, weather, physiology, phenology, biomass growth, leaf area, yield, quality, canopy temperatures, energy balance, soil moisture, nitrogen assimilation, and other data.

A systemic analysis on dwarf gene of Xingyi bantam
Authors: Wang Wen-Tao , Khan Juan , Xu Long-Xing , Chen Bing
Published: July 2017

Dwarf gene plays an important role in the poultry development. Much has been known for the regulation of sex-linkage dwarf genes, less information is available about the autosmal dwarf genes. Xingyi bantam is an endangered native breed in Guizhou, which shows different characters from sex-linkage dwarf genes about pygmy and tall foot separation, Early embryonic regularity death. In this study, we examined rare phenomenon mentioned above through establishing  pedigree. The ratio of pygmy foot individuals to tall foot individuals was 2:1 (X2 P=0.05) in Xingyi bantam pedigree, which is different from the classical ratio 3:1 of Mendel. The autocopuation (selfing) offspring of tall foot individuals were tall foot. Those results suggest that the pygmy character of Xingyi bantam is in control of Cp-cp, a pair alleles located autosomal. The pygmy foot is the dominant character to high foot, but the dominant homozygote is death. In addition, we preliminarily determined MORF4L1 was the major genes of Cp through candidate genes method. These findings may provide some insight regarding harmful genes knockout for the improved breeding of Xingyi bantam.

Haemonchus (H.) contortus is a blood feeding gastrointestinal nematode, and is considered one of the major threats for goat health and production globally. Crude somatic antigens (CSA) have been reported as sources of immunogens and provide better level of immunity against gastrointestinal nematodes. The present study aimed to quantify CSA of H. contortus worms (n=25) of both sexes followed by isolation of peptides through Sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) and their characterization. The triturate contained proteins having concentration of 1.3mg/ml as measured through Bradford assay. Seven different bands were appeared on gel ranging from 35KDa to 170KDa. The future prospects may include identification of the immunogenic peptides which can be used as vaccine candidates against H. contortus.

Published: July 2017

This study investigated the effect of purple glutinous rice bran (PRB) supplementation on performance, oxidative status and lipid oxidation in broiler. Two hundred male day old broiler chickens were randomly assigned to 5 groups of 40 birds each. Each treatment, fed the basal corn-soybean diets containing 0%, 3%, 6%, 9% and 12% of purple glutinous rice bran (PRB). Diets were formulated separately for starter and finisher phases (day 0 to 21 and day 22 to 42). Oxygen radical absorbance capacity (ORAC) in PRB supplemented groups were higher than rice bran group and depend on the supplement dose of PRB. PRB supplementation (6%, 9% and 12%) increased (P less than 0.05) weight gain (WG), average daily gain (ADG) and decreased (p less than 0.05) feed conversion ratio (FCR) compared to control group. Malondialdehyde (MDA) levels in serum from the PRB groups were lower than control group (P less than 0.05). Glutathione (GSH) levels in serum of PRB groups (6%, 9% and 12% PRB) were higher than control group (P less than 0.05). However, there were no difference between 3% PRB and control groups. No difference of lipid oxidation in breast meat after storage between PRB supplemented groups with control group (P>0.05). This study indicated that PRB supplementation in diet had positive effects on performance and oxidative status of broiler chickens but had no effect on lipid oxidation in breast meat storage

Published: July 2017

The present study was carried out to evaluate the genetic and non-genetic factors affecting fertility traits viz., number of service per conception (NSPC), service period (SP) and calving interval (CI) and genetic and phenotypic parameters of these traits in Jersey crossbred cattle, maintained at Eastern Regional Station of ICAR-National Dairy Research Institute, Kalyani, West Bengal over a period of 39 years (1976-2014). The least squares means for the NSPC, SP and CI were 1.73±0.08 inseminations, 156.37±7.47 days and 458.32±9.56 days respectively. The study revealed that all the traits were decreasing significantly with parity number. Season was important in determining service period, whereas period of calving influenced calving interval in this study. NSPC, SP and CI did not differ significantly among different genetic groups; but, half-breds of Jersey and Tharparkar (½ Jersey-½ Tharparkar) showed comparatively lower NSPC, SP and CI than half-breds of Jersey and Red Sindhi and other crosses in this study. The random effect of sire was highly significant on all the fertility traits considered in this study. Heritability estimates for NSPC, SP and CI were 0.08±0.06, 0.18±0.08 and 0.16±0.08 respectively. All the three analyzed traits had close genetic relationships. Low to moderate heritability of reproductive traits indicates slow genetic progress through selection and further improvement in reproductive performance can be made either by better management practices or including large number of polymorphic markers associated with fertility in the population to assist animal selection

Authors: Lira‐Junior Ronaldo , Öztürk Veli Özgen , Emingil Gulnur , Bostanci Nagihan , Boström Elisabeth A.
Published: July 2017

Background: Host inflammatory and immune responses play an important role in aggressive periodontitis (AgP). Thus, this study aims to evaluate levels of the innate immunity‐related markers calprotectin, colony‐stimulating factor (CSF)‐1, macrophage migration inhibitory factor (MIF), monokine induced by interferon‐γ (MIG), and matrix metalloproteinase (MMP)‐8 in serum and saliva from patients with generalized AgP and those with gingivitis or a healthy periodontium.

Methods: This study enrolled 40 individuals (17 males and 23 females; mean age 33.30 ± 9.31 years), 15 with generalized AgP, 15 with gingivitis, and 10 who were periodontally healthy. Full‐mouth periodontal examinations were performed, and serum and saliva were collected. Levels of calprotectin, CSF‐1, MIF, MIG, and MMP‐8 were measured using enzyme‐linked immunosorbent assays.

Results: In serum, mean levels of calprotectin were 2.06‐fold higher in patients with AgP than in healthy patients (P = 0.01). Serum levels of MMP‐8 were significantly elevated in patients with AgP compared with both healthy patients and those with gingivitis, by 2.60‐fold and 2.77‐fold, respectively (P = 0.03 and P = 0.009, respectively). In saliva, levels of MMP‐8 were 5.66‐fold higher in patients with AgP than in healthy patients (P = 0.02). CSF‐1, MIF, and MIG levels in both serum and saliva did not differ significantly among the groups.

Conclusions: Serum levels of calprotectin and MMP‐8 are elevated in patients with AgP. MMP‐8 levels are also increased in saliva from patients with AgP. These results support involvement of innate immune response in the pathogenesis of AgP.

O Curso em questão foi estruturado em quatro fases, nas quais o professor participante desenvolveu atividades de planejamento de ensino, aplicação desse planejamento, avaliação do conjunto da experiência e elaboração de monografia. O trabalho pedagógico (prática) do participante na própria instituição de origem constituiu o ponto de partida para seu aprofundamento teórico e também a meta a ser atingida, na forma de trabalho renovado. Entretanto, a aplicação dos planos de ensino revela que nem sempre houve adequação nas relações entre os procedimentos de ensino e as novas concepções, isto é, entre prática e teoria. A constatação, análise e avaliação dessa inadequação propiciam ao participante elaboração de planejamento mais aperfeiçoado.

Rochas são usadas como instrumentos musicais desde o surgimento da música. Litofones, do grego lithos (rocha), são instrumentos de percussão baseados em placas rochosas. Eles são similares aos mais usuais xilofones, mas com as características musicais únicas originadas de sua construção peculiar. Na Inglaterra, a história dos litofones data do século 18. Nós construímos e analisamos um litofone com o objetivo de usá-lo como ferramenta educacional no ensino de geologia e física. Um tópico organizador de interesse, a música, é o tema central na abordagem interdisciplinar introduzida aqui. De fato, no desenho do instrumento, as placas de rocha devem ser caracterizadas, com as suas relações entre frequência e comprimento estabelecidas, a fim de que notas específicas sejam selecionadas. Outro objetivo do presente trabalho é a utilização do som como ferramenta na caracterização das propriedades elásticas de materiais. Nossos resultados sugerem que a abordagem apresentada é efetiva como ferramenta educacional para uma audiência ampla.

A areia, como outros sedimentos inconsolidados, é o produto de uma importante etapa do ciclo das rochas, e seus processos de formação e acumulação, associados à dinâmica externa da Terra, são facilmente observáveis em vários cenários naturais (praias, dunas, rios, lagos). Cada grão de areia tem uma história que pode ser revelada por meio da investigação de suas propriedades, em diferentes escalas de observação e com diferentes ferramentas de análise. Neste trabalho foi elaborado um kit didático com amostras de rochas, minerais e sedimentos (areias) de diferentes localidades do Brasil e do mundo acompanhadas de fichas de atividades e conceitos teóricos. O material está sendo apresentado para professores do Ensino Fundamental e até o momento, foi positivamente avaliado.

Authors: Chaves Joselisa Maria , Santana José Carlos Barreto de , Leite Osmario Rezende , Celino Joil José
Published: July 2017

Este artigo relata os elos existentes na década de 1990 entre o grupo de ensino que culminou na criação do Programa de Pós-Graduação em Ensino e História de Ciências da Terra PEHCT do IG-Unicamp e duas universidades baianas, Universidade Estadual de Feira de Santana (UEFS) e Universidade Federal da Bahia (UFBA). Inicialmente os elos foram formados a partir da participação de quatro docentes das instituições baianas em curso de especialização em Ensino de Geociências, nas turmas de 1992 e 1994. No segundo momento esses docentes se organizaram e levaram para Feira de Santana o mesmo curso, de modo a compor o primeiro curso de Especialização da Área de Geociências da UEFS, com participação de professores da Unicamp, UEFS e UFBA. Curso que ocorreu em duas turmas, nos anos de 1995 e 1997. Os reflexos do aprendizado dos conhecimentos adquiridos pelo PEHCT são sentidos até hoje na trajetória dos autores desse artigo e daqueles que compartilharam da experiência discente e docente envolvendo a Especialização em Ensino de Geociências, sempre na busca de um melhor desempenho acadêmico em suas práticas docentes.

Proposta de conteúdos alternativos e atividades para abordagem do tema água no ensino médio
Authors: Sabino Claudia de Vilhena Schayer , Lobato Wolney , Amaral Fernando Costa , Moreira Isabela
Published: July 2017

Toda vida que conhecemos depende estritamente da água. A água como componente mítico está presente nas religiões, lendas e tradições, revelando que a cultura humana sempre reconheceu a importância deste recurso natural como indispensável para a manutenção da vida e necessária para diversas atividades socioculturais e econômicas. Apesar da abundância de água no planeta, vários países vivenciam conflitos devido à escassez do precioso líquido. Esta situação tem sido agravada pelo crescimento populacional e por diversas atividades antrópicas. A utilização abusiva e irracional, bem como a contaminação por esgotos domésticos, atividades agropecuárias, industriais e de extração mineral têm com­prometido, de forma crescente, a quantidade e a qualidade de mananciais hídricos do Planeta. Reconhecendo a educação como fundamental para a conscientização e resgate do sentimento de respeito pela água, capaz de promover a proteção e conservação dos recursos hídricos, apresentamos nesse trabalho uma proposta de conteúdos e atividades para a abordagem do tema água no ensino médio, com enfoques em Ciência, Tecnologia, Sociedade e Ambiente (CTSA).
As geociências e as tecnologias de informação e comunicação (TICs) na interface ensinar-aprender
Authors: Signoretti Vlander Verdade , Carneiro Celso Dal Ré
Published: July 2017

As tecnologias de informação e comunicação (TICs), apoiadas em conhecimentos de Geociências, podem contribuir para mudar a postura de professores e alunos da educação básica e melhorar o desempenho de alunos nos exames de avaliação de aprendizado. Na área de ensino de Ciências, os resultados têm sido preocupantes e até mesmo críticos. Este artigo propõe que modelos educacionais apoiados em Geociências e condizentes com a época atual possam contribuir para a aprendizagem significativa e para estimular o professor a criar situações favoráveis ao aprendizado. Exigem-se soluções inovadoras e abordagens que fundamentem, cada vez mais, cursos de formação de professores, pautados em computadores, para integrar as TICs à educação do aluno. Conclui-se que investir em educação nessa época de imprevisibilidade pressu­põe, além da criação de espaços reais e virtuais de comunicação, formação contínua e valorização daqueles que promovem o seu desenvolvimento. O ensino de Ciências e, conseguinte, o ensino das Geociências, representa a geração de condições para formação de cidadãos cultos e capazes de discernir de modo adequado frente às escolhas que a vida se lhes apresentará.

Formação cidadã para contrapor-se às práticas de consumo no século XXI
Authors: Scheid Neusa Maria John , Nogaro Arnaldo
Published: July 2017

O artigo objetiva aprofundar a relação entre formação cidadã e práticas de consumo. Resulta de pesquisa na literatura e ampara-se em marcos legais brasileiros e autores como Bauman (2007, 2008, 2009), Cardia e Bastos (2005), Reis (2009, 2013), dentre outros. O intuito é problematizar a respeito da função e responsabilidade da escola em propiciar uma educação de envergadura crítica e emancipadora que resulte em formação de cidadãos capazes de exercer a prerrogativa de questionar o mundo a partir dos saberes escolares. Dentre esses saberes, destacam-se os conhecimentos da área das Ciências Naturais que podem oferecer espaço para projetos interdisciplinares que oportunizem uma educação científica capaz de lançar luz na construção de uma consciência ambiental, lúcida, enquanto consumidores, capazes de agir de forma ativa e posicionar-se perante os apelos do mercado e do consumo.
