The control of disinfection by-products precursors by advanced methods of water treatment
Authors: Rajca Mariola , Włodyka-Bergier Agnieszka , Bodzek Michał 
Published: January 2018

Abstract
In the article, the results of the research on reactivity of natural organic matter in regard to disinfection by-products, specifically trihalomethanes (THM) formation, with the use of model waters, are discussed. Additionally, the evaluation of different processes used in water treatment, i.e. photocatalysis, MIEX®DOC and membrane processes, is made. It was found that the affinity of particular natural organic matter compounds to form chlorination by-products could be arranged in a series: hydrophobic fraction (HA) &gt; hydrophilic fraction (FA). The applied treatment processes efficiently decreased the concentration of disinfection by-products (DBPs) precursors and characterized with different removal mechanisms. Water treated by means of photocatalysis (specific potential of ∑THM was 30 μg/mg dissolved organic carbon (DOC) for HA and 12 μg/mg DOC for FA) revealed lower affinity to form chlorination by-products in comparison with water undergone to MIEX®DOC process (specific potential of ∑THM was 38 μg/mg DOC for HA and 29 μg/mg DOC for FA). Moreover, combination of those methods with membrane processes efficiently reduced DBPs formation potential. In nanofiltration effluents DBPs potential were very low and equalled to 50 μg/L for HA and 15 μg/L for FA.
Validation of the Portuguese Version of the International Physical Activity Questionnaire for Adolescents (IPAQA)
Authors: Ferro-Lebres Vera , Silva Gustavo , Moreira Pedro , Ribeiro José Carlos 
Published: January 2018

Background:Questionnaires have been broadly used to assess physical activity in adolescents, however validation studies, although essential, are not always performed.Objective:The present work aims to determine the validity of the Portuguese version of the International Physical Activity Questionnaire for Adolescents against 3 axis Actigraph accelerometers.Method:A cross-sectional study was conducted, with a sample of 222 adolescents, with a mean age of 15.6 years (SD=2.05). After translation and cross cultural adaptation, data obtained from the questionnaire was correlated to accelerometers data, using Spearman correlation coefficient. Percentages of agreement of physical activity tertiles obtained by each method were tested using Cohen’s Kappa. Statistical analysis was performed for the total sample, per sex and per age group.Results:A significant correlation between the questionnaire and accelerometer was found for older adolescent boys, for total physical activity (ρ=0.372;P<0.01), and for moderate to vigorous physical activity (ρ=0.428;P<0.01) No correlations were found for the younger adolescents and girls. A 42.3% agreement was found for the questionnaire and accelerometer tertiles of total physical activity.Conclusion:The concurrent validity proved that the questionnaire might be valid only for older adolescent boys. The authors consider that whenever available physical activity objective measurements should be used instead of questionnaires.

Published: January 2018

Background
Wavelet analysis has been used to locate speed variation changes in swimmers, but this elaborated technique was not so far tested in lifesavers carrying a manikin and using one upper limb and fins for propulsion.

Objective:
Our purpose was to examine the feasibility of using the wavelet analysis to locate time-points of speed variation changes in a manikin carry lifesaving race using stiff and fiber fins.

Method:
Fourteen male lifesavers with a mean age of 20.79±4.93 years performed two 25 m all-out manikin carry swimming races using one upper limb and stiff or fiber fins for propulsion. Speed was recorded with a speedometer and its variation was analysed using a wavelet transform analysis. Video recordings were used to measure stroke rate and stroke length within each race.

Results:
Wavelet analysis detected, for some lifesavers, one (stiff: 10.50±1.29 vs. fiber: 9.75±0.50 s; p>0.05) and, for other lifesavers, two time-points (stiff: 6.75±0.96 and 11.50±1.29; fiber: 7.00±1.41 and 12.00±1.83 s; p>0.05) of speed variation changes. Mean speed was no different with fin types (stiff: 1.38±0.06 vs. fiber: 1.42±0.09 m∙s-1; p>0.05), as well as average, maximum and minimum speed. Stroke rate, stroke length and stroke index did not change within each race.

Conclusion:
Wavelet analysis was effective in detecting one and two time-points of speed variation changes within a short duration manikin carry race independently of the type of fins used. Fiber and stiff fins showed similar biomechanical and speed variations within race changes.

Sustainability Reporting by Firms in the Nigerian Economy: Social versus Environmental Disclosure
Authors: Haladu Alhassan , Bt. Salim Basariah 
Published: January 2018

Purpose: There is need for specialization on individual categories of sustainability information disclosure. An attempt has been made in this study to make a comparison between the environmental and social categories of sustainability disclosure.
Methodology: Guided by the G4 sustainability reporting guidelines, environmentally sensitive companies in the Nigerian economy were analyzed for 6 years (2009-2014). Separate assessments and comparisons were made between environmental reporting and social reporting on the impact, influence and significance of their relationships using Stata13SE analytical tool.
Findings: The results shows that firms performed better on social reporting than on environmental reporting in terms of higher sustainability disclosure rates and significant relationships.
Research Implications: The current trend of reporting sustainability information disclosure under both social and environmental reporting is encouraging considering the fact that disclosure on sustainability issues in Nigeria is voluntary.
Practical Implications: Firms in environmentally sensitive sectors are disclosing sustainability information than expected.
Originality/Value: The uniqueness in comparing sustainability disclosures between environmental information and social information.

A determinação do inicio do ano hidrológico, a diferenciação dos períodos úmidos e secos, bem como a distribuição espacial da precipitação em cada período são informações fundamentais que servem como base de conhecimento climatológico para alavancagem de estudos hidrológicos em uma região. O presente trabalho teve como objetivo determinar e discretizar o ano hidrológico do estado do Tocantins, bem como mapear espacialmente a distribuição da precipitação pluviométrica dos períodos úmidos e secos. Utilizaram-se dados de 43 estações pluviométricas distribuídas no estado do Tocantins, com dados de 1977 a 2006. Os mapas das isoietas foram confeccionadas utilizando-se de SIG pelo método de interpolação matemática Topo to Raster. Os resultados mostraram que o ano hidrológico no estado do Tocantins começa no mês de outubro, sendo o seu período úmido de outubro até abril e o período seco de maio até setembro. Os maiores valores pluviométricos do período seco se encontram na porção noroeste do estado do Tocantins, onde se encontra o bioma da Amazônia. Já os maiores valores pluviométricos para o período úmido estão distribuídos nas porções centro-oeste e no extremo sudeste do estado do Tocantins. AbstractThe determination of the early hydrological year, the differentiation of wet and dry periods, as well as the spatial distribution of precipitation in each period are climatological information that serve as basic knowledge to the progress of hydrological studies in a region. This study aimed to determine and discretize the hydrologic year of the State of Tocantins, as well as spatially map the distribution of rainfall of wet and dry periods. We used data from 43 rainfall stations distributed in the state of Tocantins, with data from 1977 to 2006. The maps of isohyets were prepared using GIS by mathematical interpolation method to Top to Raster. The results showed that the hydrological year in the state of Tocantins begins in October, and its wet season from October to April and the dry season from May to September. Thehighest values of rainfall during the dry season are in the Northwest portion of Tocantins, where is the Amazon biome. The highest rainfall for the wet period are in the Midwest and portions in the extreme Southeast of the Tocantins State.

"La autonomía del estudiante dentro del espacio social y académico en la Universidad Veracruzana" Las dimensiones y regulaciones disciplinarias
Authors: Loreto Vera Pérez Buenaventura 
Published: January 2018

En esta investigación se analizan los procesos de autonomía que los estudiantes construyen en su trayecto por la universidad dentro del espacio social y sus dimensiones que son instituidas por las disciplinas (licenciaturas) universitarias. La autonomía estudiantil en el contexto de la educación superior es una actitud y una cualidad idónea para los procesos educativos en lo contextos universitarios desde las diversas dimensiones que despliegan las disciplinas académicas hacia los agentes sociales que ahí intervienen. El espacio social es un conjunto de relaciones de fuerzas objetivas que se imponen a todos los sujetos y que son irreductibles a las intenciones de los agentes individuales.
El estudiante de nuevo ingreso manifiesta un capital cultural para desplegarlo en las diferentes dimensiones que las disciplinas imponen. La autonomía educativa es una práctica dentro de los espacios en función de las regulaciones académicas en la universidad pública. El propósito es detectar las prácticas y acciones para la construcción de la autonomía en los estudiantes universitarios. El alumno quien construye estrategias para desarrollar autonomía como principio generador y organizador de prácticas y representaciones que son adaptadas a sus metas bajo la regulación de las disciplinas académicas. La práctica autonómica como disposición duradera es un conjunto de estrategias que el estudiante aplica y despliega desde un contexto particular e individual pero que son regulados por la estructura institucional.

La transición del grabado tradicional hasta la electrografía
Authors: Cázares Cerda Gisela Ivonne , Rojas Cuevas Rosa Maribel 
Published: January 2018

El presente ensayo tiene como objetivo analizar la incursión de los medios tecnológicos de la década de los 60’s al proceso tradicional de grabado. Recordemos que la gráfica es el más antiguo de los sistemas de impresión y la principal manifestación expresiva del hombre en el principio de la historia. Cabe mencionar que, a finales del siglo XVIII el grabado comenzaría a liberarse progresivamente de su hasta entonces vínculo casi exclusivo con la edición masiva y la normativa laboral que imponían los talleres profesionales, esto con el fin de asimilar planteamientos más abiertos y directos de creación.
Una de las principales características del grabado en la actualidad es como lo manifiesta Ramos Guadix en su libro Técnicas aditivas en el grabado contemporáneo: “...Consiste en que ya no se resigna a mantener sus anteriores servidumbres…” ha dejado de ser el pariente pobre del “gran arte”.
La palabra “grabado”, especialmente en el campo del arte, suele usarse como denominación general de toda clase de técnicas incisas y en relieve. El grabado se ha constituido en un lenguaje específico; ya no tiene que imitar para poner de manifiesto lo que la pintura expresa en virtud de su propia singularidad, sino que es un procedimiento autónomo.
Como consecuencia a esto fue el acercamiento de artistas de distinta procedencia a este arte, los cuales reflejan un interés por descubrir el lenguaje inherente al medio. Es por esto que los cambios a través de la historia han llevado al artista plástico al descubrimiento de nuevas herramientas, nuevos medios y por consiguiente una nueva concepción de su entorno general.
