PHYSICAL ACTIVITY AND FUNCTIONAL FITNESS IN ELDERLY LIVING IN NURSING HOMES OR USING DAY CARE CENTERS: AN EXPLORATORY STUDY
Authors: Ferreira Soraia , Leite Nilton , Marmeleira José , Raimundo Armando
Published: June 2020

Introduction. The loss of physical functions, health problems, limited support from families and few financial resources, leads to institutionalization (Sullivan & Asselin, 2013). Currently, one of the problems associated with institutionalization is the higher sedentary behavior and consequent loss of autonomy (Liu & Hu, 2015). Therefore, the main purpose of this study was to examine physical activity levels and functional fitness of older adults living in nursing homes or using day care center. Method. Thirty-two older adults (85.5 ± 5.7 years) from both genders participated in this study; 14 nursing home residents and 18 day care center users. Physical activity data were collected through accelerometry. Functional fitness were evaluated with physical fitness field tests. Results: The participants of this study have extremely low levels of functional fitness and physical activity and high levels of sedentary behavior. In nursing home residents (NH), the mean time in sedentary behavior and moderate physical activity was 9h48min/day and 2.2 min/day, respectively. In the same group, the mean time spent in light physical activity was 77.5 min/day. In day care center (DCC) users the mean time in sedentary behavior and moderate physical activity was 7h48min/day and 1.6 min/day, respectively. Older adults attending DCC showed better results than nursing home residents in the chair sit-and-reach test (DCC= -12.4±15.7 cm, NH= -22.3±4.1 cm, p=0.037), 6 min walk (DCC= 270±73.9 min, NH= 167.7±84.4 min, p<0.001) sedentary time (DCC= 7.48±0.2 hours, NH= 9.48±0.94 hours, p<0.01) and average physical activity (DCC= 82.6±18 counts/min, NH= 58.5±30.5 counts/min, p=0.03). The performance in other variables of functional fitness was not statistically different. Conclusions: Functional fitness and physical activity levels are very low in nursing home residents and in elderly users of day care center. Intervention programs are needed for these groups to reverse the decrease of physical fitness and physical activity, and promoting health and functional status.
LEARNING TO BE ENTREPRENEURIAL IN VOCATIONAL TEACHER EDUCATION
Authors: Hannula Heikki , Dorra Taru
Published: June 2020

Being entrepreneurial is a concept which has evoked interest in the context of entrepreneurship education.  It is a desirable quality not only among people already in working life but also among students, teachers and learning organizations.  Teachers are a group who by their own example can serve as a model for others.  Through their own entrepreneurial example teachers can encourage their own students to be entrepreneurial.  Therefore, it is appropriate that the entrepreneurial activities will be learned already during the teacher education. Observations of the entrepreneurial approach of two groups who began their studies at HAMK were initiated in August 2011.  Instead of the normal teacher-led training the groups of students were divided according to the tenets of Problem-Based Learning into small groups. Each group was assigned the responsibility for the independent planning, implementation and assessment of studies pertaining to vocational teacher education.  The task of the instructors was to monitor the activities and to intervene only when necessary.  In the reactions and development of the students the phases of the risk pedagogy model proposed by Paula Kyrö could be discerned- confusion, taking action and learning to take risk. The students in the groups responded twice to questionnaires addressed to them.  The first questionnaire was implemented in the beginning of studies and the second at the end of studies. The observations of the teacher educators and students were also analyzed.  It can be concluded/stated as a conclusion that in the early stage the students were confused, and partly also angry.  Taking action, however, yielded results and the prospective teachers realized that they had coped with the challenges.  Eventually in the course of implementation there actually emerged competition in regards to which group had achieved the highest quality implementation.  Thus through experiences of being teachers, the prospective teachers also learned the matters pertaining being entrepreneurial, such as responsibility and risk-taking. The purpose of this article is to describe the story of the growth of prospective vocational teachers. First we present the key concepts used in the research. Thereafter we describe the studies of the prospective teachers as a whole.  Next we introduce the prospective teachers’ and instructors’ experiences of the implementation phase.  Finally we both draw conclusions about the implementation and endeavor to stimulate discussion on the further development of entrepreneurial education.
Predicting Currency Prices and Informational Efficiency:
Authors: Sazali Abidin , Banchit Azilawati , Sun Yuewei
Published: June 2020

This study examine the predictive power of Credit Default Swaps (CDS) and the equity markets on currency exchange rate to determine whether the CDS is a better predictor as compared to the equity markets. Data sets used for the study include the Investment Grade (IG) and High Yield (HY) North American CDS indices, and iTraxx Europe index as a representative of the overall credit market conditions in Europe. The Vanguard Total Bond Market Index is included to see if CDS spread is more powerful information container than the bond market. The S&P500 index is used as controller for the effects of the US equity market and the Vanguard European Stock Index for Europe. ASX200 and NZ50 are chosen to represent the equity market conditions in Australia and New Zealand respectively. The Vector Autoregressive (VAR) model is used to analyze the simultaneous relationships between exchange rates and CDS index spreads. Granger causality test is conducted to determine the causal relationship between currency values and CDS spreads. Variance Decomposition or Forecast error variance decomposition is also used to complement the VAR analysis. The VAR analysis investigates that CDS can better capture the information in the market than other investment instruments such as bond. CDS thus may offer arbitrage opportunities for investors. In addition significant Grange-causality effects were found from IG and HY CDS spreads to currencies, which support the CDS spreads as a leading indicator of the several currencies versus US Dollar even in the financial crisis. The results of variance decomposition indicate that the contribution of the CDS market to the currency market is higher in Australian dollar, implying more carry-trades in the market.

Authors: Amaral Josineide Aquino da Silva , Bernardo Luciana Virginia Mario , Staduto Jefferson Andronio Ramundo
Published: June 2020

Este artigo trata da temática referente ao emprego formal rural na região Norte do Brasil, tendo em vista, que neste espaço registram-se diferentes transformações relacionadas à inserção de tecnologias que tendem a reduzir a necessidade de mão de obra e ainda, implica que esta seja cada vez mais qualificada. O objetivo deste trabalho é analisar o comportamento do emprego formal na agropecuária das microrregiões de Rondônia no período de 2011 a 2016. Os dados utilizados foram retirados do Cadastro Geral de Empregados e Desempregados - CAGED. Como resultado, a rotatividade no Estado de Rondônia é considerada alta para ambos os sexos. Os motivos para tal ocorrência podem estarem ligados aos avanços tecnológicos e também a grande informalidade, que é característica deste setor. Outrofato identificado para estas microrregiões, é que o emprego reduziu nos anos de 2015 e 2016, desta forma, acredita-se que a crise econômica que afetou o país,pode ter influenciado o mercado de trabalho do Estado no setor da agropecuária.

A ocupação do espaço urbano por meio da organização sistemática do uso do solo confere ao planejamento urbano a responsabilidade em atribuir organização e ordenamento nas cidades. Assim, o principal objetivo deste trabalho é identificar os principais aspectos da expansão urbana da cidade de Ferreira Gomes - Amapá, em decorrência de sua proximidade com 3 empreendimentos hidrelétricos (Usinas Hidrelétricas Cachoeira Caldeirão, Ferreira Gomes e Coaracy Nunes), avaliando especificamente as principais limitações deste processo sob a ótica do planejamento urbano e ordenamento territorial. Para a elaboração deste trabalho houve a busca por literatura específica nesta temática, recuperação de dados secundários em instituições públicas, além de pesquisas em campo para a validação de informações coletadas e identificação das principais zonas de expansão urbana e dos cenários decorrentes deste fenômeno.
Para além da China: capacidade ociosa e investimento estrangeiro direto nas formações socioespaciais africanas no início do século XXI
Authors: Santos Kauê Lopes dos
Published: June 2020

O crescimento recente da maior parte das economias africanas levou a produção de numerosas análises que condicionaram o fenômeno em questão ao dinamismo econômico chinês. Contudo, para além da influência evidente do país asiático – que opera na África por meio de acordos bilaterais, empréstimos e diferentes tipos de investimentos – deve-se também levantar quais são as condições especificas das forças produtivas das 54 formações socioespaciais africanas na atualidade. O entendimento dessas especificidades – bem como o das capacidades ociosas dos seus territórios – é o vetor fundamental de direcionamento dos Investimentos Estrangeiros Diretos, os quais revelam a arquitetura de interesses econômicos entre os chefes de Estado africanos e o resto do mundo, para além da China.

Published: June 2020

O delineamento e caracterização morfométrica de uma bacia hidrográfica são elementos fundamentais da dinâmica deste ambiente, possibilitando contribuições no planejamento e gerenciamento dos recursos hídricos. A bacia hidrográfica do rio Jaboatão localiza-se na Mata Sul do estado de Pernambuco, incluída no grupo de pequenas bacias litorâneas. Para sua caracterização morfométrica utilizou-se os preceitos teóricos de Tonello (2005) e os procedimentos metodológicos de Christofoletti, (1980), enquanto para o mapeamento geomorfológico aplicou-se a proposta de Demek (1972). Os produtos alcançados na análise morfométrica foram segmentados em três critérios: geométrico, relevo e rede de drenagem, alguns resultados principais foram: área, perímetro, coeficiente de compacidade, declividade, hierarquia fluvial, densidade de drenagem e comprimento dos canais. Na caracterização geomorfológica foi mapeado três unidades morfoestruturais e seis unidades geomorfológicas para a área de estudo. Os resultados obtidos a partir dos índices morfométricos e do mapeamento geomorfológico, possibilitaram uma análise integrada da paisagem geomorfológica da bacia do rio Jaboatão.
Para-states as an instrument for strengthening Russia's position - the case of Transnistria
Authors: Miarka Agnieszka Aleksandra
Published: June 2020

The aim of the article is to analyze and characterize the use of cooperation with the unrecognized Pridnestrovian Moldavian Republic by the Russian Federation to strengthen its position in the competition for power with the states of the euoratlantic space. During the initiated research, research methods and techniques characteristic of qualitative research were used, e.g. analysis of documents and statements of leading political decision-makers from Russia and Transnistria. The results of the research unequivocally show that strengthening the statehood of the parastatal state is one of the instruments of the Russian Federation, thanks to which it pursues its strategic goal - maintaining the position of a hegemon in the post-Soviet area, which strengthens its adaptability in strategic competition with the West for power. The functioning of the pro-Russian Transnistria in the composition of Moldova enables Russia to influence the policy of this country, exerting pressure and preventing it from dynamising the process of integration with Euro-Atlantic structures (primarily with the European Union), while retaining it in its traditional sphere of influence.
Imperial Nostalgia and Bitter Reality: The United Kingdom, the United States and Brexit, Implications for Regional Integration
Authors: Rodriguez Abelardo
Published: June 2020

Brexit and America First are undeniable examples of a return to state-based politics. This article examines the dichotomy of identity and the state, which has given rise to imperial nostalgia. Nevertheless, the decisions of the elites and the dominant majorities may lead to the fragmentation of the United Kingdom. London has shown itself to be weak in the face of China, Russia, and India and it is not clear if, over the long term, it will be influential in the global political struggles in which the latter countries are challenging the power of the United States. There are even doubts as to whether the United Kingdom can articulate a strategic alliance with the United States, due to their respective differences over relations with China and Russia. The dispute for world hegemony is also being challenged by the forces of surveillance capitalism, which not only threatens regional cooperation and immigration, but also the ecosystem and the very future of the species.

Abstract. Emissions of ice nucleating particles from sea spray can impact climate and precipitation by changing cloud formation, precipitation, and albedo. However, the relationship between seawater biogeochemistry and the ice nucleation activity of sea spray aerosols remains unclarified. Here, we demonstrate a link between the biological productivity in seawater and the ice nucleation activity of sea spray aerosol under conditions relevant to cirrus and mixed-phase cloud formation. We show for the first time that aerosol generated from both subsurface and microlayer seawater from the highly productive Eastern Tropical North Pacific Ocean are effective ice nucleating particles in the deposition and immersion freezing modes. Jet droplets aerosolized from the subsurface waters of highly productive regions may therefore be an unrealized source of effective INPs. In contrast, the subsurface water from the less productive Florida Straits produced less effective immersion mode INPs and ineffective depositional mode INPs. These results indicate that the regional biogeochemistry of seawater can strongly affect the ice nucleation activity of sea spray aerosol.

Abstract. Air in polar ice cores provides various information on past climatic and atmospheric changes. We developed a new method combining wet extraction, gas chromatography and mass spectrometry, for high-precision, simultaneous measurements of eight air components (CH4, N2O and CO2 concentrations, δ15N, δ18O, δO2/N2, δAr/N2 and total air content) from an ice core sample of ~60 g. The ice sample is evacuated for ~2 hours and melted under vacuum, and the released air is continuously transferred into a sample tube at 10 K within 10 minutes. The air is homogenized in the sample tube overnight at room temperature, and split into two aliquots for mass spectrometric and gas chromatographic measurements. Cares are taken to minimize contamination of greenhouse gases with long evacuation time, consumption of oxygen during sample storage by passivation treatment on sample tubes, and fractionation of isotopic ratios with long homogenization time for splitting. Precisions are assessed by analysing standard gases with artificial ice, and by duplicate measurements of the Dome Fuji and NEEM ice cores. The overall reproducibility (one standard deviation) from duplicate ice-core analyses are 3.2 ppb, 2.2 ppb and 3.1 ppm for CH4, N2O and CO2 concentrations, 0.006, 0.010, 0.09 and 0.12 ‰ for δ15N, δ18O, δO2/N2 and δAr/N2, and 0.67 mlSTP kg-1 for total air content, respectively. Our new method successfully combines the high-precision, small-sample and multiple-species measurements, with a wide range of applications for ice-core paleoenvironmental studies.

Published: June 2020

Abstract. Understanding of the role of ocean circulation on climate during the Late
Cretaceous is contingent on the ability to reconstruct its modes and
evolution. Geochemical proxies used to infer modes of past circulation
provide conflicting interpretations for the reorganization of the ocean
circulation through the Late Cretaceous. Here, we present climate model
simulations of the Cenomanian (100.5–93.9 Ma) and Maastrichtian (72.1–66.1 Ma) stages of the Cretaceous with the CCSM4 earth system model. We
focus on intermediate (500–1500 m) and deep (> 1500 m) ocean
circulation and show that while there is continuous deep-water production
in the southwestern Pacific, major circulation changes occur between the
Cenomanian and Maastrichtian. Opening of the Atlantic and Southern Ocean, in
particular, drives a transition from a mostly zonal circulation to enhanced
meridional exchange. Using additional experiments to test the effect of
deepening of major ocean gateways in the Maastrichtian, we demonstrate that
the geometry of these gateways likely had a considerable impact on ocean
circulation. We further compare simulated circulation results with
compilations of εNd records and show that simulated
changes in Late Cretaceous ocean circulation are reasonably consistent with
proxy-based inferences. In our simulations, consistency with the geologic
history of major ocean gateways and absence of shift in areas of deep-water
formation suggest that Late Cretaceous trends in εNd
values in the Atlantic and southern Indian oceans were caused by the
subsidence of volcanic provinces and opening of the Atlantic and Southern
oceans rather than changes in deep-water formation areas and/or reversal of
deep-water fluxes. However, the complexity in interpreting Late Cretaceous
εNd values underscores the need for new records as well as
specific εNd modeling to better discriminate between the
various plausible theories of ocean circulation change during this period.
Microbial communities and their predictive functional profiles in arid soil of Saudi Arabia
Authors: Khan Munawwar A. , Khan Shams T.
Published: June 2020

Abstract. Saudi Arabia has world's fifth largest desert and is the biggest importer of food and agricultural products. Understanding soil microbial communities is key to improving agricultural potential of the region. Therefore, soil microbial communities of semi-arid region of Abha known for agriculture and arid regions of Hafr Al-Batin and Muzahmiyah were studied using Illumina sequencing. Microbial community composition varied remarkably from other deserts and from one place to another. Highest diversity was found in rhizospheric soil of Muzahmiyah followed by Abha. Firmicutes, Proteobacteria and Actinobacteria were three main phyla detected in all the samples. Unlike other deserts, Bacteroidetes was not a major constituent and population of Firmicutes was quite high. Soils from agricultural region of Abha were significantly different from other samples in containing only 1 % Firmicutes and three to six times higher population of Actinobacteria and Bacteroidetes, respectively. Presence of photosynthetic bacteria, ammonia oxidizers, and nitrogen fixers along with bacteria capable of surviving on simple and unlikely carbon sources like DMF was indicative of their survival strategies under harsh environmental condition. Functional inference using PICRUSt show abundance of genes involved in photosynthesis and nitrogen fixation. Microbial communities show greater similarity with hot Namib desert than with cold Antarctic desert.
The added value of high resolution in estimating the surface mass balance in southern Greenland
Authors: van de Berg Willem Jan , van Meijgaard Erik , van Ulft Lambertus H.
Published: June 2020

Abstract. The polar version of the regional climate model RACMO2, version 2.3p1, is used to study the effect of model resolution on the simulated climate and surface mass balance (SMB) of south Greenland for the current climate (2007–2014).
The model data at resolutions of 60, 20, 6.6, and 2.2 km are intercompared and compared to SMB observations using three different data refinement methods: nearest neighbour, bilinear interpolation, and a statistical downscaling method utilising the local dependency of fields on elevation.
Furthermore, it is estimated how the errors induced by model resolution compare to errors induced by the model physics and initialisation. The results affirm earlier studies that SMB components which are tightly linked to elevation, like runoff, can be refined successfully, as soon as the ablation zone is reasonably well resolved in the source dataset.
Precipitation fields are also highly elevation dependent, but precipitation has no systematic correlation with elevation, which inhibits statistical downscaling to work well.
If refined component-wise, 20 km resolution model simulations can reproduce the SMB ablation observations almost as well as the finer-resolution model simulations.
Nonetheless, statistical downscaling and regional climate modelling are complementary; the best results are obtained when high-resolution RACMO2 data are statistically refined.
Model estimates in the accumulation zone do not benefit from statistical downscaling; hence, a resolution of about 20 km is sufficient to resolve the majority of the accumulation zone of the Greenland Ice Sheet with respect to the limited measurements we have. Furthermore, we demonstrate that using RACMO2, a hydrostatic model, at 2.2 km resolution led to invalid results as topographic and synoptic vertical winds exceed 10 m s−1, which violates the hydrostatic model assumptions. Finally, additional tests show that model resolution is as important as properly resolving spatial albedo patterns, correctly initialising the firn column, and uncertainties in the modelled precipitation and turbulent exchange.
The RHOSSA campaign: multi-resolution monitoring of the seasonal evolution of the structure and mechanical stability of an alpine snowpack

Published: June 2020

Abstract. The necessity of characterizing snow through objective,
physically motivated parameters has led to new model formulations and
new measurement techniques. Consequently, essential structural parameters such as density
and specific surface area (for basic characterization) or
mechanical parameters such as the critical crack length (for avalanche
stability characterization) gradually replace the semiempirical
indices acquired from traditional stratigraphy. These advances come
along with new demands and potentials for validation. To this end, we
conducted the RHOSSA field campaign, in reference to density (ρ) and specific surface area (SSA), at the Weissfluhjoch research site
in the Swiss Alps to provide a multi-instrument, multi-resolution
dataset of density, SSA and critical crack length
over the complete winter season of 2015–2016. In this paper, we present
the design of the campaign and a basic analysis of the measurements
alongside predictions from the model SNOWPACK. To bridge between
traditional and new methods, the campaign comprises traditional
profiles, density cutter, IceCube, SnowMicroPen (SMP),
micro-computed-tomography, propagation saw tests and compression
tests. To bridge between different temporal resolutions, the
traditional weekly to biweekly (every 2 weeks, used in this sense throughout the paper) snow pits were complemented by daily
SMP measurements. From the latter, we derived a
recalibration of the statistical retrieval of density and SSA for SMP
version 4 that yields an unprecedented spatiotemporal picture of the seasonal
evolution of density and SSA in a snowpack. Finally, we provide an
intercomparison of measured and modeled estimates of density and SSA
for four characteristic layers over the entire season to demonstrate the
potential of high-temporal-resolution monitoring for snowpack model validation.
Preventing Bullying: Consequences, Prevention, and Intervention
Authors: Le Menestrel Suzanne
Published: June 2020

Bullying is considered to be a significant public health problem with both short- and long-term physical and social-emotional consequences for youth. A large body of research indicates that youth who have been bullied are at increased risk of subsequent mental, emotional, health, and behavioral problems, especially internalizing problems, such as low self-esteem, depression, anxiety, and loneliness. Given the growing awareness of bullying as a public health problem and the increasing evidence of short- and long-term physical, mental, emotional, and behavioral health and academic consequences of bullying behavior, there have been significant efforts at the practice, program, and policy levels to address bullying behavior. This article summarizes a recent consensus report from the National Academies of Sciences, Engineering, and Medicine, Preventing Bullying Through Science, Policy, and Practice, and what is known about the consequences of bullying behavior and interventions that attempt to prevent and respond to it.
Fulfilling the Promise of Adolescence: Applying Developmental Knowledge to Create Systems Change
Authors: Shefska Dara , Backes Emily P.
Published: June 2020

Adolescence—beginning with the onset of puberty and ending in the mid-20s—is a distinct developmental period marking the transition between early childhood and adulthood. Although adolescence is now understood as a period of exceptional learning and growth, it is still frequently characterized as a time of increased risk and vulnerability. This mischaracterization of adolescence, combined with the deeply rooted societal inequities, has left the promise of adolescence unrealized for too many youth. A recent report from the National Academies of Sciences, Engineering, and Medicine entitled The Promise of Adolescence: Realizing Opportunity for All Youth explores the socio-behavioral and neurobiological science of adolescence and provides recommendations for how this science can be applied by youth-serving systems. This paper outlines the principles of adolescent development identified in the report and details 5practices that can be implemented by youth-serving practitioners to promote positive adolescent development and ameliorate disparities in adolescent outcomes.

Hacia una nueva edición crítica de las Alegorías de la 'Ilíada de Tzetzes' (I): ¿Dos versiones Tzetzianas?
Authors: Martins de Jesus Carlos
Published: June 2020

Escritas entre 1143 y 1146 bajo el patrocinio de Berta de Sulzbach, la que pronto sería la Emperatriz Irene, esposa de Manuel I Comneno, las Alegorías de la Ilíada son un resumen, una paráfrasis y especialmente una explicación alegórica, en más de 6.600 versos políticos, de los elementos sobrenaturales paganos del poema de Homero. Las Alegorías de Tzetzes han recibido poca atención, y solamente en los últimos años los críticos han fijado su atención en ellas. A otro nivel, el poema carece de una edición crítica actualizada, ya que no se edita desde mediados del siglo XIX (Matranga 1850; Boissonade 1851). Hasta el momento, he localizado un total de 21 códices jamás colacionados y que merecen serlo, de los 41 que lista la web de Pinakes: seis recensiones completas y otras 15 parciales, en dos casos solamente entre los scholia a la Ilíada de Homero. Crucial parece ser el hecho de que los dos testimonios manuscritos más antiguos, el Barocci 131, ff. 42-62v (D) y el Vindob. phil. gr. 305, ff. 1-145v (E), se cuenten entre esos códices no considerados. El propósito de este artículo es presentar las razones por las que una nueva edición crítica es necesaria, analizando algunos de los códices jamás utilizados para editar el poema, a la vez que busca formular algunas conclusiones previas sobre ellos, especialmente la posibilidad de que el propio Tzetzes hubiese preparado dos versiones de su obra.
Andrés Bello y la tradición clásica. Algunos problemas para su valoración
Authors: Nava Contreras Mariano
Published: June 2020

Andrés Bello es tal vez el mayor humanista de la América hispánica. Poeta, filólogo, lingüista, educador, filósofo, jurista, legislador, político y periodista, su vasta obra descansa en una sólida formación clásica que se hace evidente en todas y cada una de sus facetas. Formado durante los años finales del escolasticismo colonial en la Caracas donde nació en 1781, completó y profundizó su educación en Londres durante las primeras décadas del siglo XIX y desarrolló la mayor parte de su vasta obra en Santiago de Chile, donde murió en 1865. Su ciclo vital alcanza, pues, casi un siglo, durante el que se verificaron importantes cambios en la evolución de los estudios clásicos y del pensamiento europeo en general. Esta aproximación intenta identificar algunos de los problemas que han impedido hacer una correcta valoración del lugar esencial que ocupa la tradición clásica en la obra de Andrés Bello.

RESUMO:  O processo de urbanização das cidades sem o adequado planejamento de uso do solo provoca uma crescente impermeabilização deste, levando a constantes cheias nos centros urbanos. Entende-se que os sistemas tradicionais de drenagem resolvem apenas parte do problema, pois não agem nas causas mas somente nos efeitos. Nesse sentido o presente trabalho tem como objetivo avaliar o desempenho do pavimento permeável em relação à capacidade de infiltração das águas pluviais, visando à redução do escoamento superficial em áreas urbanas; para isso foi realizada a simulação chuvas para obter o escoamento por meio da equação de precipitação de Palmas-TO, onde foi possível aferir parâmetros de infiltração e escoamento; também foram produzidos e ensaiados blocos em concreto poroso para avaliar sua capacidade de infiltração. Na simulação efetuada sobre o pavimento permeável em blocos intertravados observou-se que ocorreu uma absorção da precipitação nos 9 minutos iniciais; já na simulação realizada sobre os blocos vazados percebeu-se que neste praticamente não ocorreu escoamento superficial. Os blocos em concreto poroso demonstraram uma ótima capacidade de infiltração, conseguindo comportar em seu interior 7,2 litros, o que significa uma infiltração instantânea de 7,2mm de chuva.

ABSTRACT: The process of urbanization of cities without the adequate planning of land use causes a growing waterproofing of this, leading to constant floods in urban centers. It is understood that traditional drainage systems solve only part of the problem, as they do not act on causes but only on the effects. In this sense, the present work aims to evaluate the performance of the permeable pavement in relation to the infiltration capacity of rainwater, aiming at reducing surface runoff in urban areas; for this, the simulation was performed rains to obtain the flow through the Palmas-TO precipitation equation, where it was possible to measure infiltration and flow parameters; blocks were also produced and tested in porous concrete to assess their ability to infiltrate. In the simulation carried out on the permeable pavement in interlocked blocks it was observed that precipitation was absorbed in the initial 9 minutes; already in the simulation carried out on the leaked blocks it was noticed that in this practically no surface runoff occurred. The porous concrete blocks demonstrated an excellent infiltration capacity, managing to accommodate 7.2 liters inside, which means an instant infiltration of 7.2mm of rain.

O objetivo deste estudo foi examinar a correlação entre a percepção de competência com o desempenho na tarefa de levantar-se do solo de idosos saudáveis. 56 voluntários participaram deste estudo transversal. O rastreio cognitivo foi verificado por meio do mini exame do estado mental e a percepção de competência foi avaliada através de uma escala em categorias. O desempenho na tarefa de levantar-se do solo foi medido por meio do número de tentativas realizadas e através do tempo para executar a tarefa. Notou-se correlação entre a percepção de competência com o número de tentativas na tarefa e com o tempo para levantar-se do solo para esta amostra de idosos saudáveis.

Caracterizado como bibliográfico, utilizou-se como fonte de informação os periódicos na área da Educação Física classificados como A2, B1 e B2, mediante os descritores atividades de aventura e esportes de aventura.  Considerando a análise dos critérios estabelecidos foram analisados 5 artigos, nas categorias objetivo, método e principais resultados. Esperava-se encontrar um contingente maior de estudos nos periódicos investigados, todavia, considera-se que o objetivo inicial foi atingido, pois revelou que há a necessidade de ampliar as investigações sobre o tema práticas corporais de aventura.
The Personal Is Pedagogical: Manifesting Queerness in an Academic Department

Published: June 2020

University visual art education departments are often regarded as having disciplinary strengths in certain areas of scholarship or research, which in turn foster specific research directions with graduate students and programs or coursework for undergraduates. In this article for a special queer-centered issue of Visual Arts Research, lead author Dana Carlisle Kletchka identifies an explicitly queer-affirming academic department that manifests particular social relations through individual politics and identities in relation to queerness, the ways in which queerness is treated throughout pedagogies and curricula, and openness to continually re-examining the ways in which power relationships are constructed and deployed in classrooms and academic spaces. She has faculty write about what it means to work in an explicitly queer-affirming environment: how it impacts their positionalit(ies) as professors, their critical pedagogical practices, and their research. Themes of equity, emancipatory teaching and learning, intersectionality, and critical social justice echoed through their responses.
EVALUATING LIQUEFACTION POTENTIAL OF PUMICEOUS DEPOSITS THROUGH FIELD TESTING: CASE STUDY OF THE 1987 EDGECUMBE EARTHQUAKE

Published: June 2020

Pumice materials, which are problematic from an engineering viewpoint, are widespread in the central part of the North Island. Considering the impacts of the 2010-2011 Christchurch earthquakes, a clear understanding of their properties under earthquake loading is necessary. For example, the 1987 Edgecumbe earthquake showed evidence of localised liquefaction of sands of volcanic origin. To elucidate on this, research was undertaken to investigate whether existing empirical field-based methods to evaluate the liquefaction potential of sands, which were originally developed for hard-grained soils, are applicable to crushable pumice-rich deposits. For this purpose, two sites, one in Whakatane and another in Edgecumbe, were selected where the occurrence of liquefaction was reported following the Edgecumbe earthquake. Manifestations of soil liquefaction, such as sand boils and ejected materials, have been reported at both sites. Field tests, including cone penetration tests (CPT), shear-wave velocity profiling, and screw driving sounding (SDS) tests were performed at the sites. Then, considering estimated peak ground accelerations (PGAs) at the sites based on recorded motions and possible range of ground water table locations, liquefaction analysis was conducted at the sites using available empirical approaches. To clarify the results of the analysis, undisturbed soil samples were obtained at both sites to investigate the laboratory-derived cyclic resistance ratios and to compare with the field-estimated values. Research results clearly showed that these pumice-rich soils do not fit existing liquefaction assessment frameworks and alternate methods are necessary to characterise them.
Genre Pedagogy and ELLs’ Writing Skills: A Theme Analysis

Published: June 2020

Coherent writing skill is an important prerequisite for academic success, especially at the tertiary level. This work studied the effect of four-month teaching intervention of genre pedagogy with Reading to Learn (R2L) approach for developing coherence in argumentative writing. It was implemented on 40 undergraduate Pakistani English Language Learners (ELLs). Pre-test evaluation informed learning gaps especially at theme choice and theme progression strategies in their argumentative writings. These gaps were addressed while planning the R2L teaching cycle of ELLs’ experimental group. They were assisted through a process of scaffolding with an aim to enable them to write coherent argumentative essays independently after learning. Then functional analysis of lexical and grammatical features of their independent argumentative writings was conducted. Findings revealed that genre pedagogy had a significant effect on students' organization of argumentative writing. This study suggests genre pedagogy as a useful instructional technique, which can improve teaching and learning writing skills at the tertiary level in Pakistan.

The collision between the Congo Craton and the Pan African fold belt of Central Africa had great impacts on the geological and tectonic points of view, notably the installation of several tectonic accidents such as faults, fractures, dikes, folds, domes. This aeromagnetic study is based on Paterson's aeromagnetic data interpretations through the use of multiple operators. These data were processed by Oasis Montaj software. The total magnetic intensity map reduced to the equator (RTE-TMI) shows important anomalies features the major important regional anomalies. Maps of the vertical gradient, analytical signal and tilt angle maps have meanwhile highlighted several short wavelength anomalies assimilated to folding, dykes, fractures or faults. The map of maxima upward to 2 km allowed to establish the structural map of the study area. It turns out that the different types of geological accidents follow ENE-WSW, ESE-WNW, NE-SW, NW-SE and even E-W and N-S directions. All these directions are very similar to the geological history of the area. Anything that seems to confirm that the study area was the scene of intense tectonic movements resulting from the collision between the Congo Craton and the Central Africa Fold Belt.
