Authors: Shelar Amruta , Sangshetti Jaiprakash , Chakraborti Shampa , Singh Ajay Vikram , Patil Rajendra , Gosavi Suresh
Published: June 2019

Background:

The drug formulations used to control mosquito vectors and helminth infections have resulted in the development of resistance, and negative impact on non-target organisms and environment.

Objective:

Plant-mediated synthesis of silver nanoparticles (P-AgNPs) using aqueous fruit peel extract of M. charantia, applications of P-AgNPs for helminthicidal activity against Indian earthworms (P. posthuma) and larvicidal activity against larvae of mosquito A. albopictus and A. aegypti.

Methods:

Aqueous fruit peel extract of Momordica charantia was used to reduce silver ions to silver nanoparticles (P-AgNPs). UV-Visible (UV-Vis) Spectroscopy, X-ray diffraction, Fourier Transform Infrared Spectroscopy and Transmission Electron Microscopy characterize synthesized P-AgNPs. The motility and survival rate of the worms were recorded for the helminthicidal activity. Percent mortality of larvae of A. albopictus and A. aegypti was recorded for larvicidal activity.

Results:

The UV-Vis absorption spectrum of P-AgNPs showed a strong surface plasmon absorption band in the visible region with a maximum absorption at 445 nm indicating the synthesis of silver nanoparticles by the addition of aqueous fruit peel extract. The XRD spectrum of P-AgNPs showed Bragg's reflection peaks 2θ value characteristics for the Face-Centered Cubic (FCC) structure of silver. The sharp absorption peak in FTIR at 1659 cm-1 assigned to C=O stretching vibration in carbonyl compounds represents terpenoids, flavonoids and polyphenols in the corona of PAgNPs; a 2 mg/mL of P-AgNPs. The concentration aqueous extract and P-AgNPs showed complete death of worms (the morphological alteration/coiling of body). A 20 ppm concentration of PAgNPs showed 85% mortality in larvae of Ae. albopictus and Ae. aegypti. P-AgNPs were nontoxic at low concentrations.

Conclusion:

The aqueous extracts played a dual role as reducing and capping agent during the biosynthesis of AgNPs as per FTIR and XRD results. The surface reactivity facilitated by biomolecule corona attached to silver nanoparticles can further help to functionalize AgNPs in various pharmaceuticals, biomedicals, and environmental applications.

Published: June 2019

Background:

Leishmaniasis is a neglected disease that does not have adequate treatment.
It affects around 12 million people around the world and is classified as a neglected disease
by the World Health Organization. In this context, strategies to obtain new, more active and less
toxic drugs should be stimulated. Sources of natural products combined with synthetic and
chemoinformatic methodologies are strategies used to obtain molecules that are most likely to be
effective against a specific disease. Computer-Aided Drug Design has become an indispensable
tool in the pharmaceutical industry and academia in recent years and has been employed during
various stages of the drug design process.

Objectives:

Perform structure- and ligand-based approaches, synthesize and characterize some
compounds with materials available in our laboratories to verify the method’s efficiency.

Methods:

We created a database with 33 cyclic imides and evaluated their potential anti-
Leishmanial activity (L. amazonensis and L. donovani) through ligand- and structure-based virtual
screening. A diverse set selected from ChEMBL databanks of 818 structures (L. donovani) and
722 structures (L. amazonensis), with tested anti-Leishmanial activity against promastigotes forms,
were classified according to pIC50 values to generate and validate a Random Forest model that
shows higher statistical indices values. The structures of four different L. donovani enzymes were
downloaded from the Protein Data Bank and the imides’ structures were submitted to molecular
docking. So, with available materials and technical feasibility of our laboratories, we have synthesized
and characterized seven compounds through cyclization reactions between isosafrole and
maleic anhydride followed by treatment with different amines to obtain new cyclic imides to
evaluate their anti-Leishmanial activity.

Results:

In silico study allowed us to suggest that the cyclic imides 516, 25, 31, 24, 32, 2, 3, 22 can be
tested as potential multitarget molecules for leishmanial treatment, presenting activity probability
against four strategic enzymes (Topoisomerase I, N-myristoyltransferase, cyclophilin and Oacetylserine
sulfhydrylase). The compounds synthesized and tested presented pIC50 values less
than 4.7 for Leishmania amazonensis.

Conclusion:

After combined approach evaluation, we have synthesized and characterized seven
cyclic imides by IR, 1H NMR, 13C-APT NMR, COSY, HETCOR and HMBC. The compounds
tested against promastigote forms of L. amazonensis presented pIC50 values less than 4.7, showing
that our method was efficient in predicting true negative molecules.
Giardiasis: An Overview
Authors: Leung Alexander K.C. , Leung Amy A.M. , Wong Alex H.C. , Sergi Consolato M. , Kam Joseph K.M.
Published: June 2019

Background:

Giardiasis is an important cause of waterborne and foodborne diarrhea, daycare
center outbreaks, and traveler's diarrhea.

Objective:

The study aimed to provide an update on the evaluation, diagnosis, and treatment of giardiasis.

Methods:

A PubMed search was completed in Clinical Queries using the key terms “giardiasis”,
"Giardia lamblia", "Giardia duodenalis" and "Giardia intestinalis". The search strategy included metaanalyses,
randomized controlled trials, clinical trials, observational studies, and reviews. The search
was restricted to the English literature. Patents were searched using the key term “giardiasis” from
www.freepatentsonline.com.

Results:

Giardiasis is caused by the protozoan parasite Giardia lamblia. The parasite is transmitted by
the fecal-oral route, frequently through ingestion of contaminated water and food or person-to person
transmission. Risk factors for infection include children in day-care settings, child-care workers, institutionalized
individuals, travelers in endemic areas, ingestion of contaminated or recreational water, immunodeficiency,
cystic fibrosis, and oral-anal sex. Approximately 50 to 75% of infected children are
asymptomatic. Other children present acute or chronic diarrhea. Direct fluorescent antibody tests that
detect intact organisms, enzyme immunoassays that detect soluble antigens, and multiplex real-time
polymerase chain reaction assays that detect specific genes of the parasite in stool samples have improved
sensitivity and specificity compared with microscopic examination of stool specimens for the
detection of Giardia trophozoites or cysts. Drugs used in the treatment of symptomatic giardiasis are
reviewed in this study. Moreover, recent patents related to the management of giardiasis are also discussed.

Conclusion:

Metronidazole, tinidazole, and nitazoxanide are drugs of choice. Resistance to common
antigiardial drugs has increased in recent years, therefore, the search for new molecular targets for
antigiardial drugs is urgently needed. In general, treatment of asymptomatic carriers is not recommended.
Purification of water supply is an important preventive measure.

An Online Minimally Guided Intervention to Support Family and Other Unpaid Carers of People With Dementia: Protocol for a Randomized Controlled Trial (Preprint)
Authors: Pinto-Bruno Ángel C , Pot Anne Margriet , Kleiboer Annet , Droes Rose-Marie , van Straten Annemieke
Published: June 2019

BACKGROUND

About three-quarters of people with dementia live in their own homes, with help from family members and/or other unpaid carers, such as friends or neighbors. Often, unpaid carers themselves experience negative consequences, such as stress, burden, and symptoms of depression or anxiety. Research has shown that these consequences can be alleviated by psychosocial and psychological interventions. Moreover, there are indications that those interventions can be effective when offered online.

OBJECTIVE

This paper describes the protocol of a randomized controlled trial (RCT) that will take place in the Netherlands to evaluate the effectiveness of iSupport, a minimally guided, internet-based intervention to improve carers’ mental health and coping resources.

METHODS

A superiority two-arm RCT comparing the effects of the online support program with a waiting list control condition will be carried out in the Netherlands. The iSupport intervention was developed by the World Health Organization and is based on cognitive behavioral therapy principles. It has five main themes divided into 23 lessons. Carers can pick and choose which lessons they want to complete. We aim to recruit 200 unpaid carers. The experimental group (n=100) will be provided with access to the intervention for 3 months following randomization; those in the waiting list control group (n=100) will be granted access to the intervention after 3 months. Assessments will be conducted at baseline (T0), 3 months after baseline (post intervention, T1), and 6 months after baseline (follow-up, T2). The primary outcome is perceived stress, measured by the Perceived Stress Scale. Secondary outcomes are symptoms of depression and anxiety, caregiver burden, sense of competence, self-efficacy, mastery, and carers’ attitudes toward dementia and their person-centered approach (ie, to what extent carers tailor the provided care to the interest, needs, and history of the person with dementia).

RESULTS

Recruitment for the trial started in January 2019. As of July 2019, we have enrolled 120 participants.
Data collection is expected to be completed by March 2020. Once all the data have been collected, we will conduct the data analyses between April and May 2020. We aim to publish our results in a manuscript by June 2020.

CONCLUSIONS

Online interventions have shown promising results in improving the mental health of carers of people with dementia. Additionally, online interventions may overcome accessibility barriers. If successful, this intervention will have important potential for implementation as a public health intervention, since costs and support by trained staff are minimal.

Developing and Applying a Formative Evaluation Framework for Health Information Technology Implementations: Qualitative Investigation (Preprint)
Authors: Cresswell Kathrin , Williams Robin , Sheikh Aziz
Published: June 2019

BACKGROUND

There is currently a lack of comprehensive, intuitive, and usable formative evaluation frameworks for health information technology (HIT) implementations. We therefore sought to develop and apply such a framework. This study describes the Technology, People, Organizations, and Macroenvironmental factors (TPOM) framework we developed.

OBJECTIVE

The aim was to develop and apply a formative evaluation framework for HIT implementations, highlighting interrelationships between identified dimensions and offering guidance for implementers.

METHODS

We drew on an initial prototype framework developed as part of a literature review exploring factors for the effective implementation of HIT. In addition, we used qualitative data from three national formative evaluations of different HIT interventions (electronic health record, electronic prescribing, and clinical decision support functionality). The combined data set comprised 19 case studies of primarily hospital settings, and included 703 semistructured interviews, 663 hours of observations, and 864 documents gathered from a range of care settings across National Health Service (NHS) England and NHS Scotland. Data analysis took place over a period of 10 years and was guided by a framework informed by the existing evidence base.

RESULTS

TPOM dimensions are intimately related and each include a number of subthemes that evaluators need to consider. Although technological functionalities are crucial in getting an initiative off the ground, system design needs to be cognizant of the accompanying social and organizational transformations required to ensure that technologies deliver the desired value for a variety of stakeholders. Wider structural changes, characterized by shifting policy landscapes and markets, influence technologies and the ways they are used by organizations and staff.

CONCLUSIONS

The TPOM framework supports formative evaluations of HIT implementation and digitally enabled transformation efforts. There is now a need for prospective application of the TPOM framework to determine its value.
The social meaning of financial wealth: Relational accounting in the context of 401(k) retirement accounts
Authors: Hayes Adam
Published: June 2019

Behavioral economics has become a dominant set of theories in explaining economic behavior, yet such behavior remains under the limited purview of psychological, cognitive, or neural approaches. This article draws on and extends Viviana Zelizer's social meaning of money framework in conjunction with new work in ‘relational accounting’ to suggest a sociological counterpoint, focusing in particular on the social and symbolic meaning attached to individual 401(k) retirement accounts. Following a market downturn, neoclassical and behavioral economics predict various types of behavioral responses, in particular loss aversion - where investors seek to increase risk-taking rather than locking in a sure loss (a loss is more painful to bear than an equivalent gain). A sociological theory that understands the shared meaning of retirement saving would predict something different, a behavior I call durable conservatism. In this article, I show how this concept better explains observed risk behavior in Americans’ 401(k) accounts following the 2002 and 2008 bear markets in stocks, and how that response differed from the behavior documented in non-retirement brokerage accounts.

Published: June 2019

Las frecuencias de defoliación y la edad de la pradera son variables estratégicas en el manejo del cultivo de la alfalfa para incrementar la biomasa producida. El objetivo del presente trabajo fue determinar el efecto de tres frecuencias de corte en el ciclo primavera-verano sobre la producción de materia seca, tasa de crecimiento y componentes del rendimiento de praderas de alfalfa de uno, dos y tres años de establecimiento. Se utilizó un diseño en bloques al azar con arreglo factorial 3 x 3 (frecuencias de corte y edad de la pradera). La mayor producción promedio de materia seca (7,528 Kg MS ha-1) y tasa de crecimiento (257 Kg MS ha-1día) se registró en praderas de un año de establecimiento (P<0.01). De otra forma, la frecuencia de corte a cuatro semanas (6,844 Kg MS ha-1) superó en 29 y 16 %, respectivamente a las frecuencias de tres y cinco semanas en la producción de materia seca. La producción de hoja y tallo en la pradera de un año de establecida superó en 45 % a la de tres años y la altura en 32 %; mientras que en la frecuencia de corte cada cuatro semanas los valores de hoja y tallo fueron 21 y 49 % superiores a tres semanas de corte y la altura en 33 %. Las variables evaluadas y su interacción determinan los componentes de rendimiento estimados en praderas de alfalfa variedad Oaxaca Criolla.

Published: June 2019

The aim of the present study was to evaluate the effect of DL-malic acid addition in Pelibuey finishing diet on average daily gain, carcass characteristics and non-carcass components. Sixteen (16) male lambs with a mean body weight of 27 ± 1.92 kg, were used in a 48-d feeding experiment. Animals were fed a high-energy diet containing corn stover, as the only forage source, with and without the DL-malic acid (MA) addition. Animals were assigned randomly in two treatments with eight lambs each: 1) Addition of4 g of DL-malic acid per kg of feed and 2) Control (diet 1 without MA). Four male lambs of each treatment were harvested after feeding experiment to measure carcass characteristics and non-carcass components. Lambs fed with MA presented a larger (P<0.05) Longissimus lumborum muscle area. Nevertheless, there were no effects (P>0.05) of MA on daily average weight gain and non-carcass components weight. In conclusion, addition of 4 g DL-malic acid to a high-energy feed enhances muscle accretion, which improves carcass quality of finishing lambs.

Published: June 2019

La crianza de camélidos sudamericanos domésticos, alpaca y llama, es la principal fuente de subsistencia en la zona altoandina peruana. El objetivo del estudio fue evaluar las características de manejo y transporte hacia el camal de los camélidos sudamericanos, considerando los criterios basados en el bienestar animal, usando las lesiones contusas halladas en la carcasa como indicador. Se recolectó información del camal municipal de la ciudad de Huancavelica, Perú. Se seleccionaron 203 canales y se revisaron después de la faena para observar la presencia de lesiones. Se registró información sobre la cantidad de animales transportados, detalles del transporte y características del manejo de los animales. De las 203 canales evaluadas se contabilizó un total de 1,418 lesiones con un promedio de 6.9 ± 0.2 por carcasa, además se registraron cuatro animales con contusión generalizada (1.9 %). Se contabilizaron 27 medios de transporte, siendo la mitad de ellos autos (50.0 %). La presentación de lesiones grados 2 y 3 están asociadas al traslado en cualquier tipo de vehículo (OR= 2.20; IC95%: 1.27 – 3.82) y a la no restricción de visión (OR= 2.26; IC95%: 1.66 – 3.06). También las lesiones extensas están asociadas al tiempo de espera pre-sacrificio mayor a las 24 h (OR= 1.42; IC95%: 0.99 – 2.03). Se evidencia que las malas características de los vehículos, malas condiciones de transporte y manejo, aumentan la probabilidad de encontrar lesiones en las canales. Por lo tanto, no se cumplen con los criterios de bienestar animal durante el manejo y transporte de los camélidos sudamericanos.

Dentro de las producciones pecuarias, las enfermedades entéricas tienen un papel importante, ya que generan severas pérdidas económicas derivadas de la mortalidad, depresión del crecimiento y disminución del índice de conversión. Rotavirus es considerado una causa importante de gastroenteritis viral aguda en humanos y animales jóvenes en todo el mundo, estando asociado a diarreas deshidratantes en granjas de producción animal. El objetivo de este estudio fue identificar rotavirus en granjas de producción cunícola ubicadas en la región sur-oriente del Estado de México a través de RT-PCR. Se recolectaron muestras de 39 pequeñas granjas de traspatio ubicadas dentro de los 13 municipios que conforman la región estudiada. Un total de 147 muestras se analizaron, 99 de conejos sanos y 48 de conejos con signología entérica, de las cuales se identificó Rotavirus en 9 de ellas (18.7 %), mientras que en conejos sanos no hubo identificación. Los resultados concuerdan con la suposición de que en conejos con signología entérica, los virus parecen tener un papel importante, pero no decisivo, y que la participación de rotavirus no es determinante para la presentación de la enfermedad. Se plantea la posibilidad de que Rotavirus no sea endémico en granjas cunícolas de la región sur-oriente del Estado de México, encontrándose ocasionalmente, sin inducir episodios entéricos graves de forma individual; no obstante, podría ser un factor importante en la presentación de brotes entéricos en asociación con otros agentes patógenos. Este es uno de los primeros reportes de la presencia de Rotavirus en conejos con signología entérica en México.

Authors: Torres-Osorio Viviana , Urrego Rodrigo , Echeverri Zuluaga José Julián , López-Herrera Albeiro
Published: June 2019

La producción de embriones in vitro es una de las biotecnologías de la reproducción animal que ha presentado mayor desarrollo en las últimas dos décadas; sin embargo, los resultados exitosos en estos procedimientos dependen de múltiples factores, entre ellos la presencia de especies reactivas de oxígeno, debido a que el proceso de fertilización in vitro y la manipulación de los gametos y embriones expone a las células a factores endógenos y exógenos que pueden afectar los mecanismos de defensa antioxidante y por consiguiente la calidad de los gametos y embriones. En esta revisión se discutirán algunas fuentes de especies reactivas de oxígeno, el uso de antioxidantes enzimáticos, no enzimáticos y polifenólicos para disminuir el estrés oxidativo en los procesos de producción in vitro de embriones, y su efecto sobre la calidad de los oocitos y embriones, la expresión génica y su competencia para el desarrollo embrionario.

Published: June 2019

Limit merupakan materi utama dalam pembelajaran kalkulus yang telah dikenalkan dan dipelajari mahasiswa sejak jenjang sekolah menengah atas. Namun tidak sedikit mahasiswa masih mengalami kesulitan dalam mempelajari dan memahami materi limit di tingkat awal perguruan tinggi. Seorang mahasiswa tidak hanya harus memiliki pengetahuan prosedural saja, namun juga perlu memiliki pemahaman konseptual tentang limit. Artikel ini membicarakan tentang cara mengidentifikasi pengetahuan prosedural dan pemahaman konseptual mahasiswa terhadap materi limit. Adapun metode yang digunakan untuk mengidentifikasi pengetahuan prosedural dan pemahaman konseptual tersebut adalah dengan memberikan tes kepada mahasiswa berupa soal-soal yang berkaitan dengan materi limit. Soal-soal tes tersebut didesain sederhana dengan tujuan untuk menghindari kesalahan yang muncul disebabkan oleh tingkat kesulitannya. Temuan hasil tes dengan soal-soal yang telah didesain tersebut menunjukkan bahwa terdapat mahasiswa dapat menyelesaikan soal-soal limit dengan baik secara prosedural, namun mereka memiliki permasalahan dalam menyelesaikan soal yang berkaitan dengan pemahaman konseptual. Hal tersebut mungkin disebabkan pembelajaran tentang limit yang mereka dapatkan di jenjang sekolah menengah atas lebih berorientasi pada penyelesaian soal-soal limit secara prosedural saja.

ROMANTISMO, ESPORTE E CINEMA: BOBBY JONES – A LENDA DO GOLF
Authors: Peil Luciana Marins Nogueira , Lovisolo Hugo Rodolfo , Lovisolo Hugo Rodolfo
Published: June 2019

Este texto parte da hipótese de que na representação do esporte os principais pressupostos e categorias do Romantismo configuram suas narrativas dominantes. O Romantismo aportou a linguagem tanto para falar sobre o esporte como para produzir os sentimentos sobre ele. No caso, tomar-se-á a particular narrativa do cinema no filme Bobby Jones – A lenda do Golfe para mapear e interpretar os pressupostos e núcleos do pensamento romântico. Na biografia filmada de Bobby Jones, os aspectos básicos do Romantismo, como a noção de Gênio; a angústia da cisão; a valorização do prazer; a busca da unidade; a autenticidade; a organicidade e a valorização da natureza estão presentes, organizando a narrativa. O filme trabalha dentro de uma perspectiva de reencantamento do mundo através de sua mensagem de valorização dos aspectos sensíveis em detrimento dos aspectos utilitários. O esporte, e aqui especialmente o Golfe, mostra-se como o grande fim e meio de nossa integral realização humana, nos moldes conhecidos do Romantismo.

Trata-se de uma reflexão sobre os processos de criação na dança contemporânea, o engajamento do corpo na ação, os investimentos na sensorialidade, os riscos do movimento. A metodologia concerne à narrativa das experiências vividas por três coreógrafos e seus processos criativos. A interpretação privilegiou uma reflexão estética com base em Paul Valéry, Gilles Deleuze e Maurice Merleau-Ponty. As noções elaboradas permitem refletir sobre a plasticidade do corpo e sua capacidade de incorporação do mundo por meio da criação de um espaço expressivo no qual se instala a dramaturgia do corpo, do espaço, do tempo, dos mundos imaginários e simbólicos.

Published: June 2019

O levantamento e análise do estado da arte da produção do conhecimento referente aos estudos do lazer no Brasil – a partir de suas características internas e da conjuntura mais ampla – permitiram localizar quatro grandes ciclos da produção do conhecimento. Neste trabalho aprofundamos a investigação sobre o primeiro ciclo, orientadas pelo entendimento de que a explicação para a produção de idéias deve ser buscada nas características da formação social brasileira no período. Buscamos reconhecer, no movimento contraditório das forças produtivas e das relações de produção em desenvolvimento no Brasil, os interesses pelo controle e preenchimento do tempo livre com conteúdos culturais diversificados. No processo de desenvolvimento da indústria como força motriz do desenvolvimento brasileiro, verificamos configurar-se no período uma política educacional de caráter conformador dos interesses da classe operária aos interesses da burguesia brasileira.
PARQUES URBANOS DE BARCELONA: A RELAÇÃO ENTRE A DIVERSIDADE NAS FORMAS DE APROPRIAÇÃO E A SEGURANÇA A PARTIR DE USOS PRINCIPAIS E COMBINADOS
Authors: Rechia Simone , Betrán Javier Oliveira
Published: June 2019

A intenção é analisar o modelo de parques, praças e ruas de Barcelona. A ênfase está na relação existente entre diferentes formas de apropriação e a segurança desses espaços a partir dos usos principais e combinados. Os procedimentos metodológicos foram: aplicação de protocolo desenvolvido no GEPLEC/UFPR, imagens fotográficas e filmagens.  Concluímos que em Barcelona alguns espaços públicos contemplam tais formas de usos co-relacionados, os quais dependem de uma série de fatores, entre eles o planejamento urbano, o qual deve buscar conectar espaços que garantam a diversidade de experiências, a segurança, e, portanto, a “vida pública” nas grandes cidades.
REPRESENTAÇÃO SOCIAL DA MULHER BRASILEIRA NAS ATIVIDADES FÍSICO-DESPORTIVAS: DA SEGREGAÇÃO À DEMOCRATIZAÇÃO
Authors: Mourão Ludmila
Published: June 2019

O objetivo deste estudo, é descrever a significação das representações sociais associadas à mulher brasileira nas atividades físico-desportivas a partir de 1 870, época que se caracteriza pela tendência a excluí-la dessas atividades, até 1950, quando se verifica um processo generalizado de democratização de seu acesso ao campo esportivo, que culmina com a primeira Olimpíada Feminina, ocorrida no Rio de Janeiro. Lançando mão de abordagens múltiplas, o estudo considera: a) depoimentos de intelectuais brasileiros médicos, juristas e educadores envolvidos com a temática mulher e esporte, no último quarto do século passado e primeiro deste século (Nísia Floresta, João da Matta Machado, Rui Barbosa, Fernando de Azevedo, Orlando Rangel Sobrinho e Afrânio Peixoto),- b) técnicas de entrevista semi-estruturada com informantes de elite, que se constituem em ícones do processo de emancipação da mulher brasileira no/através do esporte: Maria Lenk, Vara Vaz, Aída dos Santos e Roselee Viana Ribeiro); e c) documentos da mídia, sobretudo a respeito dos Jogos da Primavera, Olimpíada Feminina organizada pelo Jornal dos Sports de 1949 a 1972. The aim of this study is to describe the meaning of social representations associated with Brazilian women in physical-sport activity from 1870, when women tended to be excluded from these activities, to 1 950, when there was a widespread process of democratization of women's access to sports, which culminated in the first Womens Olympic Games, in Rio de Janeiro. With the support of multiple methodological approaches, the study considers: (a) the testimony of Brazilian intellectuals
A MODELAÇÃO DO DESENVOLVIMENTO A PARTIR DA ANÁLISE DE TRAJETÓRIAS LATENTES. UM ESTUDO APLICADO ÀS APTIDÕES MOTORAS
Authors: Maia José Antônio Ribeiro
Published: June 2019

Este trabalho pretende relançar a discussão em torno da idéia do desenvolvimento das aptidões motoras, sobretudo da necessidade em trilhar espaços da análise quantitativa das diferentes trajetórias percorridas por crianças e jovens na flecha do seu tempo cronológico. E apresentada uma abordagem crítica às estratégias analíticas e aos delineamentos utilizadas por pesquisadores das Ciências do Desporto; proponho uma "nova" metodologia para interpretar o fenômeno da mudança intra-individual nas alterações inter-indivíduos nas suas trajetórias desenvolvi-mentistas. A metodologia de análise das trajetórias latentes é apresentada e justificada a partir de um exemplo empírico, mostrando o seu enorme valor para estudar, de modo normativo e diferencial, problemas nucleares do desenvolvimento de aptidões e habilidades motoras em crianças e jovens. Esta metodologia procura congregar as idéias nor-mativistas e diferencialistas, dado estudar em simultâneo o sujeito e o grupo, o comportamento das médias no tempo e as diferenças entre sujeitos permitindo a inclusão de preditores que governam as trajetórias desenvolvimentalistas individuais. This paper aims at the discussion of the idea of the development of motor abilities, specially the need for its quantitative analysis with new methodologies. An emphasis is made upon different developmental trajectories of children and youth. Limited conceptual and analytical approaches used by sport scientists are critically reviewed and a new analytical strategy is presented to study intra-individual change within interindividual differences in their development pathways. This new methodology - latent trajectory analysis - is briefly presented and applied to an empirical problem, showing its richness to study normative and differential developmental problems related to motor abilities and motor skills in children and youth. This methodology tries to analyse, simultaneously, the views of normative and differential developmentalists since it deals with the individual subject and the group, the mean changes over time and the differences among subjects. It allows, also, the inclusion of predictors of change that govern the individual developmental trajectories.

A inovação nessa edição vai por conta da Seção Mercosul, cujo objetivo é aprofundar o diálogo com estudantes, professores e pesquisadores da Comunidade IberoAmericana. Nosso pensamento é que o Mercosul não pode e não deve caracterizar-se somente por aspectos econômicos nas relações que se estabelecem entre os países membros. Acreditamos que entre os povos Ibero-Americanos a convivência deve ser pautada também pela fraternidade e pelo enfrentamento solidário dos problemas sociais que afligem a maioria dos viventes no continente. Nesse sentido, a integração cultural baseada no diálogo esclarecido pode contribuir para tal fim. Buscando esse tipo de comunicação, a partir dessa edição da Revista Movimento, estaremos publicando textos no idioma espanhol, oportunizando aos nossos irmãos do Mercosul a interlocução e sua inclusão nos debates e nas reflexões que se estabelecem no âmbito do movimento humano, da Educação Física e das Ciências do Esporte, tanto no Brasil como na América do Sul.

SOBRE O ESPORTE PARA CRIANÇAS E JOVENS
Authors: Gaya Adroaldo
Published: June 2019

Vou utilizar-me de Sobre o Esporte para Crianças e Jovens Especial . I um texto cujo o título é: O Jogo de Bola entre os Espelhos. Através desta analogia tento demonstrar que todo o conhecimento sobre o esporte (e não só) pode ter pretensão de validade. Todavia, seja como for, este conhecimento representará sempre uma visão parcial do fenômeno maior. Jamais interpretará a realidade em todo o seu significado. De outra maneira poderíamos dizer que é evidente que qualquer disciplina das ciências do esporte pode constituir subsídios1 para a compreensão deste fenômeno da cultura corporal. A fisiologia, a biomecânica, a bioquímica, a psicologia, a antropologia a sociologia, etc, enfim qualquer área de estudo científico tem sua legitimidade efetiva para colaborar com o edifício teórico sobre o esporte. Mas, tenho claro, nenhuma delas isoladamente tem legitimidade para requerer para si a hegemonia do discurso.
