Authors: Lins Jr. José Raymundo
Published: November 2018

A língua estrangeira, enquanto elemento primordial de uma outra cultura deve favorecer ao reconhecimento de identidades nacionais e não a supervalorização de uma sobre outra(s). O presente artigo tem por finalidade apresentar a Política Linguística adotada pela Base Nacional Comum Curricular (BRASIL, 2014; BRASIL, 2016c; BRASIL, 2016b) na adoção da língua inglesa como obrigatória no Ensino Médio. Nossa reflexão propõe-se, inicialmente, uma análise da construção deste documento e sua real representatividade a ponto de garantir-lhe o status de democraticamente legítimo (GRAMSCI, 1978; MIGNOLO, 2000) e, em seguida, quais as Políticas Linguísticas (SCHIFFMAN, 1996; SPOLSKY, 2004; SHOHAMY, 2006) priorizadas nos conteúdos estabelecidos na segunda versão do documento e se estas colaboram com perspectiva da diversidade linguística em diferentes contextos que entende a relação dinâmica entre a língua e a sociedade. Nesse estudo refletimos sobre a relevância das políticas linguísticas adotadas na Base, visando a utilidade da língua inglesa na sociedade brasileira, através do ambiente escolar como instrumento de interação da linguagem.
O Discurso Político de Michel Temer: Uma Análise à Luz da GSF e da ACD
Authors: Da Silva Francisco Leones Alves , De Souza Vilmar Ferreira
Published: November 2018

O Brasil tem vivido recentemente tempos bastante conturbados em sua história política. Pela segunda vez, um presidente é deposto acusado de cometer crime contra a Constituição. Nesse contexto, este trabalho investiga como estas relações se fazem presentes na materialidade do discurso do então presidente Michel Temer. Entendendo o discurso como constitutivo das práticas sociais e, portanto, ideológico, analisar o primeiro pronunciamento de Temer como presidente se faz necessário para se compreender o seu papel no atual contexto histórico-político brasileiro. Este trabalho objetiva responder, basicamente, à seguinte pergunta de pesquisa: Como o atual presidente Michel Temer representa, linguisticamente, a si mesmo e ao seu governo, em seu primeiro pronunciamento à nação como Presidente da República? Para tanto, nos utilizamos a Gramática Sistêmico–Funcional, em particular, a metafunção ideacional, com o seu sistema de transitividade, como instrumento de descrição linguística, e a discussão dos achados foi feita a partir da Análise Crítica do Discurso (ACD), com foco em sua terceira dimensão, em específico, na noção de ideologia na análise de discurso político. Os resultados apontam para a proeminência de processos materiais, através dos quais Temer representa seu governo como dinâmico e progressista ao passo que representa o governo anterior como retrógrado e inoperante.
Removal of Pharmaceutical Contaminants in Wastewater Using Nanomaterials: A Comprehensive Review
Authors: Chauhan Anjali , Sillu Devendra , Agnihotri Shekhar
Published: November 2018

Background:

The limitless presence of pharmaceutical contaminants in discharged wastewater has
emerged as a threat to aquatic species and humans. Their presence in drinking water has although raised substantial
concerns, very little is known about the fate and ecological impacts of these pollutants. As a result, these pollutants
are inevitably introduced to our food chain at trace concentrations. Unfortunately, the conventional wastewater
treatment techniques are unable to treat pharmaceuticals completely with practical limitations. The focus has now
been shifted towards nanotechnology for the successful remediation of these persistent pollutants. Thus, the current
review specifically focuses on providing readers brief yet sharp insights into applications of various nanomaterials
for the removal of pharmaceutical contaminants.

Methods:

An exhaustive collection of bibliographic database was done with articles having high impact and citations
in relevant research domains. An in-depth analysis of screened papers was done through standard tools. Studies were
categorized according to the use of nanoscale materials as nano-adsorbents (graphene, carbon nanotubes), nanophotocatalysts
(metal, metal oxide), nano-filtration, and ozonation for promising alternative technologies for the
efficient removal of recalcitrant contaminants.

Results:

A total of 365 research articles were selected. The contemporary advancements in the field of nanomaterials
for drinking and wastewater treatment have been thoroughly analyzed along with their future perspectives.

Conclusion:

The recommendations provided in this article will be useful to adopt novel strategies for on-site removal
of the emerging contaminants in pharmaceutical effluents and related industries.

Authors: Zhu Jian , Wang Yitian , Yu Wei , Xia Kaishun , Huang Yuluan , Wang Junjie , Liu Bing , Tao Huimin , Liang Chengzhen , Li Fangcai
Published: November 2018

Background:

Long suspected as transcriptional noise, recently recognized, long non-coding RNAs (lncRNAs) are emerging as an indicator, biomarker and therapy target in the physiologic and pathologic process. Mesenchymal stem cells and embryonic stem cells are important source for normal and therapeutic tissue repair. However, the mechanism of stem cell differentiation is not completely understood. Research on lncRNAs may provide novel insights into the mechanism of differentiation process of the stem cell which is important for the application of stem cell therapy. The lncRNAs field is still very young, new insights into lncRNAs function are emerging to a greater understanding of biological processes.

Objective:

In this review, we summarize the recent researches studying lncRNAs and illustrate how they act in the differentiation of the mesenchymal stem cells and embryonic stem cells, and discuss some future directions in this field.

Results:

Numerous lncRNAs were differentially expressed during differentiation of mesenchymal stem cells and embryonic stem cells. LncRNAs were able to regulate the differentiation processes through epigenetic regulation, transcription regulation and post-transcription regulation.

Conclusion:

LncRNAs are involved in the differentiation process of mesenchymal stem cells and embryonic stem cells, and they could become promising indicator, biomarker and therapeutic targets in the physiologic and pathologic process. However, the mechanisms of the role of lncRNAs still require further investigation.
Sustaining the National Health Insurance Scheme in South Africa: The Roles and Challenges of Community Health Workers
Authors: Tshitangano Takalani G. , Olaniyi Foluke C.
Published: November 2018

Background:

The provision of universal health coverage is acknowledged as a priority goal for healthcare systems globally. In South Africa, the National Health Insurance system has been endorsed as a funding model for the provision of universal health coverage for South Africans. Community Health Workers have contributed to better universal health coverage outcomes in many countries. A study in India revealed that coverage of health care practices is positively correlated with the knowledge level of Community Health Workers. In South Africa, there is a difference in the duration of training of Community Health Workers in different provinces, especially in Vhembe District.

Objective:

This study aimed to assess Community Health Workers’ knowledge regarding their roles and describe their challenges within the context of National Health Insurance.

Methods:

Qualitative design was used to collect data from 33 participants who formed five focus groups comprising six to eight members each. Ethical principles of research such as permission, informed consent, voluntary participation and anonymity were observed. Data was analysed using thematic data analysis technique guided by Tesch open coding method.

Results:

The findings revealed that Community Health Workers lack adequate knowledge regarding the roles they are expected to play within Ward Based Outreach teams. Some of the challenges they face include transportation to clients’ homes and poor reception in households.

Conclusion:

A review of the South African Qualification Authority health promoter unit standards is recommended coupled with the mentorship of Community Health Workers by retired nurses to help them understand their roles better.
MiRNAs: Biology, Biogenesis, their Web-based Tools, and Databases
Authors: Tafrihi Majid , Hasheminasab Elham
Published: November 2018

Introduction: MicroRNAs (miRNAs), which are evolutionarily conserved, and endogenous non-coding RNAs, participate in the post-transcriptional regulation of eukaryotic genes. The biogenesis of miRNAs occurs in the nucleus. Then, in the cytoplasm, they are assembled along with some proteins in a ribonucleoprotein complex called RISC. miRNA component of the RISC complex binds to the complementary sequence of mRNA target depending on the degree of complementarity, and leads to mRNA degradation and/or inhibition of protein synthesis. miRNAs have been found in eukaryotes and some viruses play a role in development, metabolism, cell proliferation, growth, differentiation, and death.

Objective:

A large number of miRNAs and their targets were identified by different experimental techniques and computational approaches. The principal aim of this paper is to gather information about some miRNA databases and web-based tools for better and quicker access to relevant data.

Results:

Accordingly, in this paper, we collected and introduced miRNA databases and some webbased tools that have been developed by various research groups. We have categorized them into different classes including databases for viral miRNAs, and plant miRNAs, miRNAs in human beings, mice and other vertebrates, miRNAs related to human diseases, and target prediction, and miRNA expression. Also, we have presented relevant statistical information about these databases.
Can Real-time Biofeedback of Foot Clearance Data be used to Assist with Gait Rehabilitation following Stroke?, NHMRC
Authors: Begg Rezaul
Published: November 2018

A new intervention for falls-risk minimization is proposed by providing additional visual sensory information to increase foot-ground clearance in order to walk more safely. A randomised controlled trial will be employed to assess the effects of biofeedback on foot-ground clearance
during gait training. The outcome will be innovative biofeedback-based gait training that could significantly enhance existing stroke rehabilitation programs. Biofeedback is the provision of information, most commonly visual or auditory, of internal biological processes that would not otherwise
be sensed. The theoretical and practical significance of biofeedback is in applications such as neurological rehabilitation, where it can augment, or substitute for, the lost information provided by normally functioning sensory systems. The group is undertaking a major National Health
and Medical Research Council (NHMRC) funded project in collaboration with two Melbourne hospitals (Royal Melbourne and Austin Hospital) using visually presented biofeedback of foot-ground clearance to re-train walking in stroke patients.
Unravelling how adjuvants work, and what their roles are in vaccination and allergy
Authors: Kuroda Etsushi
Published: November 2018

The development of safe and effective vaccines is essential to tackling a variety of infectious diseases. Vaccines fall into a variety of different types, depending on how they are produced. The inclusions of live attenuated, inactivated, toxoid, subunit or conjugate vaccines contain
key antigens which are used in the vaccines to encourage the immune system to mount an immune response. This response will eventually trigger the creation of targeted memory B cells that persist and can quickly multiple and tackle future interactions with the disease agent. This is the cornerstone
of our adaptive immune system, protecting us against getting many diseases more than once. Vaccines often contain more than just the antigen. They also commonly contain a facilitating agent known as an adjuvant. Adjuvants enhance the effect of the vaccine, making it more likely to work and
to work well, however, it has long been thought that they themselves confer no immunity if presented to the immune system without the antigen. One of the biggest mysteries in immunology is how exactly adjuvants function. They certainly do function, often making the difference between
an ineffectual vaccine and one that can help tackle a disease. However, answering the question of 'how?' may well prove key to the development of better vaccines and even treatments in other fields of human disease. Investigating the mode of action of adjuvants is Dr Etsushi Kuroda, Senior
Researcher at NIBIOHN, Japan. He works in the Center for Vaccine and Adjuvant Research under Dr Ken J. Ishii in a large lab with multiple researchers focussing on a different aspect of adjuvants. Kuroda's field of interest is the role of pollution particulates as adjuvants to allergy and asthma.
Kuroda explains his area of research in greater detail: 'Particle pollutants that we focused on are also thought to be adjuvants and induce inflammation when they are inhaled. There are pros and cons in adjuvants, and excessive activation of immune cells by adjuvant might induce immune-related
diseases such as allergic inflammation.'
Feasibility of Using a Commercial Fitness Tracker as an Adjunct to Family-Based Weight Management Treatment: Pilot Randomized Trial (Preprint)

Published: November 2018

BACKGROUND

Fitness trackers can engage users through automated self-monitoring of physical activity. Studies evaluating the utility of fitness trackers are limited among adolescents, who are often difficult to engage in weight management treatment and are heavy technology users.

OBJECTIVE

We conducted a pilot randomized trial to describe the impact of providing adolescents and caregivers with fitness trackers as an adjunct to treatment in a tertiary care weight management clinic on adolescent fitness tracker satisfaction, fitness tracker utilization patterns, and physical activity levels.

METHODS

Adolescents were randomized to 1 of 2 groups (adolescent or dyad) at their initial weight management clinic visit. Adolescents received a fitness tracker and counseling around activity data in addition to standard treatment. A caregiver of adolescents in the dyad group also received a fitness tracker. Satisfaction with the fitness tracker, fitness tracker utilization patterns, and physical activity patterns were evaluated over 3 months.

RESULTS

A total of 88 adolescents were enrolled, with 69% (61/88) being female, 36% (32/88) black, 23% (20/88) Hispanic, and 63% (55/88) with severe obesity. Most adolescents reported that the fitness tracker was helping them meet their healthy lifestyle goals (69%) and be more motivated to achieve a healthy weight (66%). Despite this, 68% discontinued use of the fitness tracker by the end of the study. There were no significant differences between the adolescent and the dyad group in outcomes, but adolescents in the dyad group were 12.2 times more likely to discontinue using their fitness tracker if their caregiver also discontinued use of their fitness tracker (95% CI 2.4-61.6). Compared with adolescents who discontinued use of the fitness tracker during the study, adolescents who continued to use the fitness tracker recorded a higher number of daily steps in months 2 and 3 of the study (mean 5760 vs 4148 in month 2, P=.005, and mean 5942 vs 3487 in month 3, P=.002).

CONCLUSIONS

Despite high levels of satisfaction with the fitness trackers, fitness tracker discontinuation rates were high, especially among adolescents whose caregivers also discontinued use of their fitness tracker. More studies are needed to determine how to sustain the use of fitness trackers among adolescents with obesity and engage caregivers in adolescent weight management interventions.
Theoretical and Epistemological Thoughts on Archaeology and Experimental Lithic Technology
Authors: Nami Hugo G.
Published: November 2018

In the wide field of archaeology, stone tool remains are one of the main pieces of evidence used for assessing knowledge and understanding of the archaeological record. To cope with its analysis and interpretation as a branch of experimental archaeology, one field of research that has become more notable is experimental lithic technology. Based on experience and development of this discipline in the southern cone of South America, and with the aim of contributing to the growing theoretical perspectives in this field, this paper addresses the theoretical and epistemological issues that deal with theoretical, variability, classification, and deontological concerns.
Aves marinas varadas en la bahía de Coquimbo, norte de Chile: ¿Qué especies y cuántas mueren?
Authors: Portflitt-Toro Matías , Miranda-Urbina Diego , Luna-Jorquera Guillermo
Published: November 2018

El monitoreo de las aves varadas en las playas puede proporcionar información sobre sus causas de muerte, tales como la captura incidental en actividades de pesca o derrames de petróleo. Durante un año fue monitoreada mensualmente la Bahía de Coquimbo, norte de Chile para cuantificar el número de aves marinas varadas. Se encontraron 395 aves marinas muertas de las cuales 382 fueron identificadas y agrupadas en 21 especies. Las especies más abundantes fueron los piqueros con 115 individuos (30%), el cormorán guanay con 83 individuos (22%) y la gaviota dominicana con 65 individuos (17%). Las especies más abundantes y frecuentes fueron las que anidan en el Sistema Costero de Coquimbo. La mortalidad afecta principalmente a las aves marinas que se alimentan de la anchoveta, que es el principal recurso objetivo de la pesca con redes de cerco. Se sugiere que la mortalidad incidental causada por la pesca es crónica y relativamente constante durante el año. Se requiere un programa de monitoreo a largo plazo para mejorar la estimación de la mortalidad y los factores que influyen en la interacción de las aves marinas con las artes de pesca.
Parasite community of a temporal notothen fish from intertidal rocky pools in south-central Chile: Is it similar to other fish from the same habitat?
Authors: Muñoz Gabriela , Vildoso Francisco , George-Nascimento Mario
Published: November 2018

Notothen fishes (Nototheniidae) have been recorded on the coasts of South America, from 35°S to southern. Little is known about the biology of intertidal notothen fishes or their relationships with other species, including parasites. Here, we analyzed the parasitic fauna of a species of Notothenia collected from the rocky intertidal of Lebu, south-central Chile (36°S) and compared the parasite community of this host with other 9 fish species commonly found in rocky intertidal pools. Among the tested species, Notothenia sp. had the highest parasite richness (21 parasitic taxa vs. 1 to 9 parasitic taxa). The composition of parasite species was different among fishes, with similarity indices between 0 and 33%. The parasite composition of Notothenia sp. was most similar to Calliclinus geniguttatus (27%). The most abundant and prevalent parasites found in Notothenia sp. were the copepod Caligus cf. cheilodactyli, Tetraphyllidea larvae, anisakid nematodes, and several acanthocephalan species, which are typical of other fish from the subtidal and bento-demersal zones. Therefore, we conclude that the juveniles of Notothenia sp. were a few months old and had their parasites when reaching the intertidal zone, acquired some generalist parasites during their stay in this habitat, such as Holobomolochus chilensis and Lecithaster macrocotyle. Most notothen fishes are from Antarctic and Sub-Antarctic waters, therefore, it is possible that this fish came from another habitat but also from the austral region of South America. Notothenia sp. could not be specifically identified because of different results between morphological and genetic analyses.

This study investigated the environmental impact of offshore floating sea cages and the influence of runoff on cage fish farming in SE Gulf of California via the analysis of the physico-chemical profiles of the water column and sediments, located in SE Gulf of California, Mexico. Water and sediment samples were analyzed for physico-chemical parameters. In general, nitrates showed the highest concentrations of nutrients in the potential impact station (1.92 mg L-1). The results displayed temporal variations in the NH4+, NO3-, and PO43- in the water column as well as variations in the clay and organic matter in the sediment. The observed trends of these parameters were toward higher concentration in the potential impact and control stations.
Bathybembix bairdii (Mollusca: Gastropoda: Calliotropidae) as a potential fishery resource off western Mexico
Authors: Hendrickx Michel E. , Suárez-Mozo Nancy Yolimar
Published: November 2018

Bathybembix bairdii, the Baird's top shell, is reported for the first time from off the Baja California Peninsula west coast and the southwestern coast of Mexico, at depths of 710-2,093 m. Environmental conditions measured near bottom were: 2.10 to 5.81 °C, 34.40 to 34.63 (salinity), and <0.12-0.90 ml L-1 O2. The species was found mostly in muddy sediments dominated by silt (56.5-87.0%) (Baja California) or in sediments with a significant proportion of sand (63.5 to 88.5%) (southwestern Mexico). Shell height varied from 10.0 to 53.7 mm, with high proportion of large specimens in shallower water off Baja California. Densities varied from 1.75 to 207.45 org. ha-1 off Baja California and from 5.25 to 50.72 org. ha-1 in southwestern Mexico. Estimated maximum biomass occurred off southwestern Mexico (2.2 kg ha-1). Relationship between height and total weight (shell plus soft part) and between height and soft part weight were both highly correlated (R2: 0.933 and 0.928, respectively). Soft part weight varied from 29 to 62% of total weight and proportion increased with size. Mega invertebrate species associated with B. bairdii included 47% of decapod crustaceans, 35% of echinoderms, and 18% of mollusks. As a by-catch species regularly found in deep-water trawls, B. bairdii could represent a valuable resource for human consumption.

Authors: De la Linde-Rubio Antonio , Tierno de Figueroa J. Manuel , López-Rodríguez Manuel J. , Sánchez-Tocino Luis
Published: November 2018

Records of mortality after a high temperature event in 2014 in the white gorgonian Eunicella singularis were compiled in six different locations around the Chafarinas Islands. Quadrats were used to quantify dead colonies, colonies affected by epibionts and healthy colonies at different depths. No relationship was found between depth and percentage of affected colonies; however differences in the mortality among sites were detected. On average, 43% of the colonies of E. singularis were found dead, 21% damaged and 36% healthy. These results highlight the need of further researches for monitoring the colonies of this species considering future scenarios of rising temperature.

Destacando a questão da apropriação dos mecanismos culturais em

situação de 'exclusão" nas favelas do Brasil, o artigo aponta para a

emergência de uma literatura "marginal" no país e para a dominação da

linguagem escrita nos segmentos sociais que foram, por séculos,

excluídos por sua "iliteralidade". A autora associa a questão da natureza

do espetáculo aos ataques palestinos ocorridos, nos últimos trinta anos, e

analisados a partir do arquivo da BBC. O ponto de partida é o 11 de

setembro, evento que expressa o domínio sobre a arte da representação e

é expressão máxima da guerrilha de controle dos espetáculos midiáticos.

Essas diferentes experiências de controle da representação têm um

aspecto comum: a violência com que são representadas, fazendo das

convenções do espetáculo cinematográfico e da mídia espetáculos do 49

terror. Nesse sentido, ocupam lugares chaves no mundo contemporâneo,

a começar pelo próprio controle sobre os mecanismos de construção da

representação.

Um rizoma, um Ateph, ou mais uma característica de um meio - Para além de uma descrição da comunidade virtual Orkut no ambiente da ciberdemocracia e da comunicação em rede.
Authors: Da Silva Filho Wilson Oliveira
Published: November 2018

Ao analisar a partir de uma breve relação entre o conceito de Rizoma de Guies Deleuze e Félix Guattari e da metáfora criada por Jorge Luis Borges, o Aieph, compreendendo também um vinculo com o pensamento sobre o meio, pretende-se com esse artigo discutir um pouco mais sobre a comunidade virtual, Orkut, que movimenta uma legião de internautas. Pensar o conceito de comunidade através de uma nova forma de pensar o meio digital levando em conta seu caráter de uma nova constituição sobre democracia e nos limites das multiplicidades no contemporâneo pode ser detectar que o fenômeno possui uma dimensão ainda não conhecida de sua potencialidade e de seu poder de transformar as relações, constituindo uma nova subjetividade do mundo em rede. Na esteira do pensamento sobre os blogs, o Orkut surgiria como só mais uma novidade ou estabeleceria novas possibilidades de ler o ativismo na rede e a própria noção de comunidade? Essa questão sintetiza a idéia dessas linhas pensando que uma 'ciberutopia' pode surgir das comunidades virtuais.

A obrigatoriedade do diploma e a identidade jornalística no Brasil: um olhar pelas margens
Authors: Albuquerque Afonso de
Published: November 2018

O artigo investiga o problema da delimitação das fronteiras que definem a prática legitima do jornalismo, tendo por referência a obra de Barbie Zelizer. Destaca, a este respeito, a sua proposição de que o profissionalismo se desenvolveu de forma

incipiente no jornalismo e que a identidade jornalística é construída com base em narrativas compartilhadas, através das quais os jornalistas se constituem como uma comunidade interpretativa autorizada. Visto que o modelo de Zelizer foi elaborado tendo por referência o jornalismo americano, é preciso verificar a sua aplicabilidade ao jornalismo de outros países. O artigo faz isso em duas etapas. Na primeira,

considera, de modo comparativo, o desenvolvimento do profissionalismo no jornalismo em diferentes países da Europa Ocidental. Na segunda, discute o impacto que o

“Hubo un tiempo que fue hermoso”: una relectura de la relación entre “rock nacional”, mercado y política
Authors: Boix Ornela
Published: November 2018

En este artículo, interrogamos el rock nacional con nuevas preguntas instaladas por las investigaciones más recientes sobre música, producidas en el contexto local. Hacemos una historia del campo de estudios y mostramos que los intentos de estabilizar esta categoría son más problemáticos de lo que se supone. Asimismo, argumentamos que la literatura trabaja de forma reduccionista los vínculos del llamado rock nacional con el mercado y con la política. Sugerimos que pensar los procesos históricos en términos de origen explica en parte este problema y ofrecemos posibilidades de análisis que enriquecerían nuestro conocimiento del fenómeno.

Los gobiernos democráticos no son los únicos que realizan esfuerzos y formulan estrategias políticas para la generación de consenso, la última dictadura cívico-militar argentina también buscó aumentar sus apoyos y disminuir los sectores disidentes. Con este trabajo cuestionamos la temprana hipótesis del empleo exclusivo del terror y la coerción por parte de este régimen, para demostrar que la población también fue gobernada mediante tecnologías de convencimiento. En este trabajo analizaremos una serie de encuestas y sondeos de opinión realizados por el gobierno en 1981 para medir el ánimo social y conformar un mapa de debilidades y fortalezas que utilizó para recuperar el direccionamiento político. El general Viola asumió un gobierno jaqueado por la crisis económica y social, y mantuvo un sondeo diario de las actitudes y juicios de la población a fin de medir y obtener información que utilizó para la construcción de estrategias comunicaciones y de propaganda.

El envejecimiento disminuye la autonomía e independencia de los adultos mayores. La fuerza muscular, flexibilidad y marcha son mejoradas con actividad física. Objetivos: comparar los resultados de las características físicas, los tests funcionales y tests de marcha entre grupos de adultos mayores activos y sedentarios; Metodogía: se evaluaron dos grupos, cada uno con 13 individuos, de adultos mayores activos y sedentarios - el nivel de actividad física fue autoreportado - mediante cinco tests funcionales y dos tests de marcha. Resultados: el grupo de activos presentó mayor circunferencia abdominal e índice cintura-cadera. No fueron encontradas diferencias para los tests funcionales y de marcha  entre los dos grupos. Con diferentes ecuaciones fueron encontradas diferencias intra grupo: la ecuación de Enright & Sherrill, 1998 y Troosters, Gosselink & Decramer, 1999 para los dos grupos; para la ecuación de Enright, 2003 para el grupo de sedentarios. Conclusiones: Solamente hubo diferencia entre grupos para dos variables físicas. Se sugiere que la intensidad de la actividad física debe ser sistematizada y monitoreada para que sea posible alcanzar los resultados y beneficios de una vida activa.
Ano internacional do Esporte e Educação Física: o Sistema ONU e a pedagogia da hegemonia
Authors: Melo Marcelo Paula
Published: November 2018

Os organismos internacionais cumprem relevante papel pedagógico no âmbito da atual fase da sociedade capitalista e na correlação de forças entre as classes sociais. O Sistema ONU (Secretaria Geral, suas agências e Fundos) ocupa papel de grande relevo nesse processo. O conjunto de questões que marcam o projeto capitalista neoliberal incide no campo dos esportes e o Sistema ONU passou a conferir um papel de destaque aos esportes. Isso implicou na criação de uma série de programas e ações. O substrato dessas ações radica na emergência de princípios caros ao projeto neoliberal nesse campo.

O estudo trata de investigar a prática esportiva do tênis nos primeiros clubes no Brasil, buscando evidências sobre os métodos utilizados para ensinar o esporte. Para tal, recorreu-se à revisão bibliográfica e a análise documental das fontes coletadas para a pesquisa. A interpretação das informações revelou que a prática do tênis desenvolveu-se de forma significativa nos clubes e alastrou-se para outros espaços sociais. Também há indícios que nos clubes foram experimentados e modificados métodos de ensino do tênis pelos instrutores/professores ao longo do tempo.
Factors influencing long term tomato seed production under contract farming

Published: November 2018

Hybrid tomato seed production under contract farming in Northeast Thailand has been declining after three decades of initial introduction. However, some growers in some villages remain as long-term growers. This study was designed to identify factors influencing their long-term production decision making process. A purposive sampling technique was used to select the study sites and key informants for in-depth semi-structured interviews. Group interviews were conducted to validate the data. The contract hybrid tomato seed production system is a centralized model. It is based on a two-way contractual relationships between the company and the individual grower. The companies specify production systems and produce quality standards at a fixed time and price. They support a complete package of inputs credit, loans and extension services to the growers. Costs of all inputs and loans are deducted from the seed payment. These costs are usually forgiven when the crop fails through no fault of the growers. The growers cannot produce hybrid tomato seeds without a contract due to the proprietary germplasm. The quality of the product and marketing are also controlled by the companies. The companies must depend on the farmers’ knowledge however, for the management and technical skills. Therefore, the companies must allow considerable flexibility and leniency in enforcing the terms of the contracts. As a result, knowledgeable and skillful growers are vital factors in sustaining long term hybrid tomato seed production. Furthermore, grower’s personal characteristics stand out as an important factor for long term production. This is why the companies are lenient and flexible with the growers to sustain their mutual benefit.
Climate of the Europe. Past, Present, Future

The advancing warming of Earth climate has largely been influenced by natural causes, i.e. increased Solar activity and decreasing volcanic activity on Earth. It still remains unknown which part of the warming process results from the increased amount of Solar energy reaching Earth surface, and which is being caused by the anthropogenic part of atmosphere’s greenhouse effect. The facts speaking in favour of natural factors include synchronic changes of mean air temperature on the Northern hemisphere between 1856 – 2002, mean consecutive 11-year Wolf numbers, and the location of mass centres of the four biggest planets in our Solar system.

The theory of natural causes of climate warming is also backed by synchronic changes in carbon dioxide concentration and paleotemperature within the last 160,000 years and 450,000 years, recreated based Antarctica ice cores. Warmings occur every 100,000 years. They are triggered by increased Solar radiation in large geographic latitudes resulting from changes in Earth orbit and Earth axis slant (according to the already accepted Milankovic theory).

“Parallelism” of changes in CO2 concentration and paleotemperture shows that the atmospheric content of carbon dioxide is shaped by the amount of Solar radiation reaching Earth – through shifts in ocean waters temperature. It is more credible to claim that “CO2 concentration in atmosphere rises along with the amount of Solar radiation reaching Earth surface (i.e. when it is warmer).”
The Size of the Basic Unit in Geographical Analysis
Authors: Suchożebrski Jarosław
Published: November 2018

In geographical analysis such as mathematical classification and modeling, the study area is divided into a network of basic (quasi-homogenous) units. A technique often used in the delimitation of the basic unit to be analyzed is the division of the study area into a network of uniform geometrical figures (block-centered grid). This article presents two objective methods for dividing the surface area of the study region into a network of basic units. The geometric method makes it possible to determine the optimal size of the basic unit, relative to the surface area being analyzed. This method may be used in analysis conducted on a regional scale, in which case the analysis and the results are characterized by a greater degree of generalization. Geostatistical methods (semivariance analysis and nearest-neighbor analysis) make it possible to determine the size of the cell in the grid of quasi-homogenous units, based on the spatial variation of elements in the natural environment and on the placement of data points. These methods can be recommended for the analysis of small areas (e.g. small drainage areas), when highly detailed data and results are required.
Geopolitical Essence of Central Europe in Writings of Eugeniusz Romer
Authors: Jędrzejczyk Dobiesław
Published: November 2018

Eugeniusz Romer maintained that the notion of Central Europe, introduced at the end of the 19th century by German geographers was of a distinct geopolitical character. The thesis that Poland is situated in a transitional zone between the Western and the Eastern Europe denies Poland the right to an independent political existence. Romer’s opinion was that the location of Poland is characterised by its bridge-like situation between the Baltic and the Black Seas. This location determines the geopolitical identity of Poland as well as its rights to independence. Romer’s arguments, supported by cartographic, demographic and ethnographic research became the basis for the determination of the area and the borders of Poland at the peace conference in Paris (1919 – 1920).
Development of the Jewish Urban Settlement in Israel in View of the Theory of the Innovation Diffusion
Authors: Mularczyk Mirosław
Published: November 2018

Presentation of the current state and development tendencies of Jewish urban settlement in Israel against the innovation diffusion theory.

Analysis of the growth tempo of the number of cities in Israel allows to claim that urban Jewish settlement network develops in accordance with the innovation diffusion model.

Assuming that the theory fits the urban settlement development pattern on the surveyed territories, the directions taken by the impulses sent by innovation sources have been determined based on the corridor settlement development theory.

The hypothesis has been verified against the factors influencing spatial development directions of the Jewish urban settlement using a dynamic (synchronic-comparative) diffusion process simulation model, built with the Monte Carlo method.

The conducted analyses and procedures verifying the model distribution of Jewish settlement in Israeli cities in 1948, 1967 and 1992 allowed to conclude that the highest stochastic concordance between the model accounting for the innovation diffusion theory elements, and the real distribution of Jewish settlement cities holds for 1948 and 1967. According to the diffusion innovation theory, these years correspond to the colonisation stage. The model diversifies from reality for late 1967, when network densification process was coming to an end and city competition stage was starting.

Despite statistical validity of the hypotheses, the results show that besides the analysed factors influencing the development of Jewish urban settlement, other variables, not accounted for in the model, are also significantly influential.
