Photographic public sphere: Identity building with vernacular photography
Authors: Näsi Altti
Published: May 2020

The foundation of the article is based on the notion that self-disclosure is one of the most significant factors of contemporary vernacular photography. Argued through conceptual analysis and real-life examples, the role of self-disclosure is analysed in relation to the somewhat institutionalized functions of vernacular photography: (1) preserving memories, (2) maintaining and creating new social relationships, (3) self-presentation and (4) self-expression. The article sheds light on the widespread use of cameraphones and how the role of self-disclosure differs notably within the four chosen functions, since its absence among private photographs contributes to personal and unique memories; and within shared photographs, it defines how people want to be seen by others and themselves. The benefits and challenges of private and shared photography are also evaluated.
An Intelligent Multi-Resolutional and Rotational Invariant Texture Descriptor for Image Retrieval Systems
Authors: Dhingra Shefali , Bansal Poonam
Published: May 2020

To find out the identical or comparable images from the large rotated databases with higher retrieval accuracy and lesser time is the challenging task in Content based Image Retrieval systems (CBIR). Considering this problem, an intelligent and efficient technique is proposed for texture based images. In this method, firstly a new joint feature vector is created which inherits the properties of Local binary pattern (LBP) which has steadiness regarding changes in illumination and rotation and discrete wavelet transform (DWT) which is multi-resolutional and multi-oriented along with higher directionality. Secondly, after the creation of hybrid feature vector, to increase the accuracy of the system, classifiers are employed on the combination of LBP and DWT. The performance of two machine learning classifiers is proposed here which are Support Vector Machine (SVM) and Extreme learning machine (ELM). Both proposed methods P1 (LBP+DWT+SVM) and P2 (LBP+DWT+ELM) are tested on rotated Brodatz dataset consisting of 1456 texture images and MIT VisTex dataset of 640 images. In both experiments the results of both the proposed methods are much better than simple combination of DWT +LBP and much other state of art methods in terms of precision and accuracy when different number of images is retrieved.  But the results obtained by ELM algorithm shows some more improvement than SVM. Such as when top 25 images are retrieved then in case of Brodatz database the precision is up to 94% and for MIT VisTex database its value is up to 96% with ELM classifier which is very much superior to other existing texture retrieval methods.
Evaluation of ensiled soy sauce by-product combined with several additives as an animal feed
Authors: Sadarman Sadarman , Ridla Muhammad , Nahrowi Nahrowi , Ridwan Roni , Jayanegara Anuraga
Published: May 2020

Aim: The present experiment aimed to evaluate the use of different additives, i.e., lactic acid bacteria (LAB) inoculant, tannin extract, and propionic acid, on the chemical composition, fermentative characteristics, and in vitro ruminal fermentation of soy sauce by-product (SSB) silage.

Materials and Methods: SSB was subjected to seven silage additive treatments: Fresh SSB, ensiled SSB, ensiled SSB+LAB, ensiled SSB+2% acacia tannin, ensiled SSB+2% chestnut tannin, ensiled SSB+0.5% propionic acid, and ensiled SSB+1% acacia tannin+1% chestnut tannin+0.5% propionic acid. Ensiling was performed for 30 days in three replicates, and each replicate was made in duplicate. The samples were evaluated for their chemical composition and silage fermentation characteristics and were tested in an in vitro rumen fermentation system.

Results: In general, the nutrient compositions did not differ among the tested SSBs in response to the different additives used. The addition of tannins, either acacia or chestnut, and propionic acid significantly decreased the pH of the ensiled SSB (p<0.05). The addition of several additives (except LAB) decreased the ammonia concentration in SSB silage (p<0.05). The total volatile fatty acids in the in vitro rumen fermentation profile of the ensiled SSB were not significantly altered by the various additives applied. The addition of some additives, i.e., ensiled SSB+LAB and ensiled SSB+2% acacia tannin, reduced the digestibility values of the SSB (p<0.05). Different silage additives did not significantly affect methane production, although the addition of acacia tannins tended to result in the lowest methane production among treatments.

Conclusion: The use of additives, particularly 2% acacia tannins, can reduce proteolysis in SSB silage.
Threshold Concentration of Surfactant Agent in Feedstocks Used for Low-Pressure Powder Injection Molding
Authors: Ali Ghalya , Demers Vincent , Côté Raphaël , Demarquette Nicole R.
Published: May 2020

In this work, 32 different feedstocks formulated from four different stainless steel powders and two wax-based binder systems (paraffin wax and beeswax), for which the proportion of two different surfactant agents was varied from 0 to 5 vol.% (stearic acid and oleic acid), were obtained. The viscosity of the feedstocks according to the shear rate was measured using a rotational rheometer. The moldability of the mixtures was assessed using the injected length following real-scale injections. The results show that the influence of surfactant agents on viscosity depends on the main binder constituent used in the feedstock formulation. The moldability of paraffin wax–based feedstocks was significantly affected by the proportion of the surfactant agents, whereas that of beeswax-based feedstocks was not affected by the presence of stearic acid or oleic acid. It was confirmed that as little as 0.20 vol.% of stearic acid or oleic acid in paraffin wax–based feedstock is enough to produce the surfactant effect, leading to a significant increase in the moldability of feedstocks (e.g., fourfold longer injected length). This threshold concentration of surfactant agent in paraffin wax–based feedstocks was also established with different powder grades, shapes, and sizes. For feedstocks containing paraffin wax and surfactant agents, the presence of a discontinuity in the viscosity profiles was confirmed not to be an experimental artifact because the phenomenon was reproduced using three different measurement approaches.

Sintered preforms made of an aluminum powder metallurgy (PM) 2000 series metal matrix composite designed for press-and-sinter applications were forward extruded at 450°C under displacement rates of 254 mm/min and 2,032 mm/min. The material was highly responsive to extrusion under these conditions and was readily formed into products that included 10-mm and 15-mm solid round bars as well as C-channel and round tubing profiles, wherein extrusion ratios ranged from 11:1 to 76:1. Significant metallurgical improvements were also observed in the seemingly defect-free products. These included gains in tensile yield strength (10 %), ultimate tensile strength (20 %), and tensile ductility (400 %) when compared to the nonextruded T6 counterpart. Such enhancements were attributed to the attenuation of full theoretical density, disruption of the residual oxide network, and the development of a partial duplex fiber texture with strong <111> and moderate <100> fiber components within the extruded PM products.
Uneasy Listening
Authors: Rubinstein Yair
Published: May 2020

This paper explores the cultural ramifications of music generated by artificial intelligence (AI). Deploying complex algorithms to create original music productions, AI’s automation of human authorship may suggest a radically new sonic form. However, its creators have preferred to use its tools to mimic established musical genres from the past. As a result, notable AI-music programmers like composer David Cope and software developers Flow Machines have galvanized the public’s interest in AI-generated music not by creating completely alien sonic forms, but by simulating popular styles like rock and classical music. Consequently, listeners often report AI music sounds unnervingly familiar rather than aesthetically inaccessible. I argue that it is precisely AI music’s devotion to uncannily approximating its human forebears that makes it such an interesting object of contemporary sonic production. It also provides a useful historical parallel to a short-lived musical movement from the 2000s known as sonic hauntology. Much like AI programmers, producers of sonic hauntology applied digital technology to the sonic past. However, they confronted it in more deliberately political and subversive ways. Sampling sonic artifacts and cultural marginalia from the mid-20th century, sonic hauntologists created eerie soundscapes designed to challenge mass culture’s erasure of history’s political depth, or what Fredric Jameson famously referred to as late capitalism’s cultural logic of postmodernism. While AI music has yet to be exploited in this way, I argue its inherently “uneasy listening” carries the potential to further sonic hauntology’s project of repurposing the sonic past to estrange listeners from the present moment.
Travels with Jack
Authors: Smith Jacob
Published: May 2020

Nonprofit arts organization the ZBS Foundation began as a “media commune” in the early 1970s and continues to the present day: a period that spans dramatic changes in American radio culture and audio technology. The key creative figure at ZBS is the writer and producer Thomas Lopez, whose work serves as a case study in a “post-network” style of radio drama, one shaped by multitrack editing, field recording, and the ethos of the 1960s counterculture. The ZBS aesthetic comes into sharpest focus in the Jack Flanders adventure series, which demonstrates how ZBS adapted a “theater of the mind” approach to radio drama to create a “theater of the mind-body” that re-accentuated earlier conventions of the radio adventure serial for a countercultural audience. Lopez’s increasing use of field recordings to structure his narratives established a formal tension between the inner exploration of the hero’s psyche and an encounter with different cultures. I chart the development of this formal tension in ZBS’s theater of the mind-body and argue that Lopez’s work with ZBS is a bridge across multiple eras of radio, an archive of enduring characters and distinctive styles of storytelling, and a sonic laboratory for the fostering of cultural dialogue through sound.

Analiza modelnih otopina nakon ispitivanja migracije provedena je pomoću UV/Vis spektroskopije. Zbog utvrđene hidrolize PHB-a pod utjecajem modelnih otopina nemoguće je odrediti migraciju MMT-a iz kompozita PHB/MMT. Diferencijalna pretražna kalorimetrija (DSC) potvrdila je razgradnju PHB-a. Provedenim istraživanjem ukazalo se na potencijal uporabe UV/Vis spektroskopije kod ispitivanja utjecaja modelnih otopina na polimerne kompozite.
Del gobernante divino al dirigente paterno
Authors: Catalán Miguel
Published: May 2020

El artículo estudia el argumento mítico  y religioso del paternalismo político en virtud del cual la sociedad es hija del gobernante, en especial del monarca. Del mismo modo que el rey en tanto Dios crea a la humanidad desde la nada, también el rey en tanto padre se presenta como su engendrador o fundador. El presente análisis tiene una estructura diacrónica que comienza en el estadio mítico-religioso de los pueblos africanos y de la China clásica, atraviesa la Antigüedad grecorromana y el modelo medieval de la familia como modelo de la sociedad, y termina con la teoría política de John Filmer sobre el origen bíblico de la monarquía.
The Ancestral Caenorhabditis elegans Cuticle Suppresses rol-1
Authors: Noble Luke M , Miah Asif , Kaur Taniya , Rockman Matthew V
Published: May 2020

Genetic background commonly modifies the effects of mutations. We discovered that worms mutant for the canonical rol-1 gene, identified by Brenner in 1974, do not roll in the genetic background of the wild strain CB4856. Using linkage mapping, association analysis and gene editing, we determined that N2 carries an insertion in the collagen gene col-182 that acts as a recessive enhancer of rol-1 rolling. From population and comparative genomics, we infer the insertion is derived in N2 and related laboratory lines, likely arising during the domestication of Caenorhabditis elegans, and breaking a conserved protein. The ancestral version of col-182 also modifies the phenotypes of four other classical cuticle mutant alleles, and the effects of natural genetic variation on worm shape and locomotion. These results underscore the importance of genetic background and the serendipity of Brenner’s choice of strain.
Images of the Lithuanian Political Elite in the Eyes of Citizens
Authors: Vaičiukynaitė Justina
Published: May 2020

The article aims to reconstruct the concept of the Lithuanian political elite from the citizens’ perspective, focusing on how the concept is perceived, how the political elite is recognized in social life, and what attributes are associated with this particular concept. Applied qualitative in-depth interview data gathering and inductive data analysis approaches demonstrate that the Lithuanian political elite concept consists of two images: legalistic and charismatic. Although these two images are completely divergent, they are intertwined and successfully coexistent in the minds of citizens. The citizens are tending to apply either a legalistic or charismatic image depending on the circumstances: the legalistic image is applied in recognizing and describing the political elite as an externally existing referent; meanwhile, the charismatic image is applied in building up the normative political elite portrait.
Ginger value chain analysis: A case of smallholder ginger production and marketing in hills of central Nepal
Authors: Raj Dahal Bhishma , Rijal Swodesh
Published: May 2020

Abstract. Having high export potential and profitable to farmers, Ginger is an important spice crop of hills of central Nepal; however, ginger farmers continue to experience low productivity and were forced to share large profit with unscrupulous traders; further, they are traumatized by fluctuation of price and other problems. In this context, a study was undertaken in Sindhuli, a part of Central Nepal for analyzing value chain of ginger. A pretested semi-structured questionnaire was administered among 120 randomly selected farmers and 10 traders involved in ginger enterprise for the past two years. A face-to-face interview was scheduled to obtain data during October-November, 2018. Compound annual growth analysis revealed that area, production and yield of ginger were increasing at the rate of 1.73%, 1.65% and 0.95%, respectively, over the last seven years and price of ginger, over the past thirteen years, increasing at the rate of 3.28%. Value chain analysis revealed that producer, traders (wholesaler and exporter), retailer and consumer were the major actors involved. Farmers received substantial margin – 55% of the retail price, but the rest of the profit was shared to unscrupulous traders. B/C ratio of ginger farming in the study area was 2.42 revealing that ginger farming was a profitable business; with investment of Rs1.0 (0.0088US$) in ginger, farmers earned additional 1.42 rupees. Low productivity of ginger in the research area was caused by severe incidence of rhizome rot. In addition, price fluctuation, lack of processing and storing infrastructure, timely unavailability of rhizome seed, paucity of improved variety, and lack of farmers’ knowledge on improved cultivation practices were the major constraint of ginger farming. Overall, our study points out that solving the constraints, accessing new market, and organizing co-operatives are crucial for sustainable value chain development.

Published: May 2020

Abstract. This study assessed apiculture enterprise to determine the output elasticity of production, returns to scale, technical efficiency and profitability in Adamawa State, Nigeria. A total of four agricultural zones out of six, and 108 apiarists were selected through purposive and simple random methods, respectively. Descriptive statistics, stochastic frontier production function and budgetary technique were used in the analyses of data. Findings revealed that all (100%) the respondents were males within the age range of 21-30 years (44.44%). The majority of apiarists (87.0%) were married with household size of 1-10 persons (77.78%) and 50.0% of them had secondary school education. A larger proportion (37.0%) had between 6 and 10 years of beekeeping experience with 41.67% earning monthly income of N11000 (USD30.8) – N20000 (USD56.0) from other sources. Further, the findings revealed that labor and number of hives had reassuring influence on the industry, while age, education and experience could be used to reduce inefficiency in the industry to improve efficiency status. The apiarists also had mean technical efficiency of 89.9%, while the inefficiency estimate was only 10.1%. In terms of profitability, beekeeping in the study area was found to have had a high gross margin of N16800.00 (USD47.0) and net farm income of N15225.97 (USD42.6) for every beehive in a cropping season. The major constraints to beekeeping reported in the area included beehive crops theft, high propensity of bees’ stings, inadequacy of finance, rampant bush burning and deforestation, among others. It was concluded that beekeeping in the study area was found to be profitable and technically efficient. Improving beekeeping business in the area, among other things, would require its modernization and involvement of female participants, provision of soft credit facilities and enactment of stringent forestry laws to check unwholesome forestry practices.

O desenvolvimento como processo de mudança cultural: as conexões entre excedente e estruturas sociais na visão de Celso Furtado
Authors: Bianconi Renata , Coutinho Mauricio C.
Published: May 2020

Resumo O objetivo deste artigo é apresentar a visão de Furtado sobre excedente e estrutura social, sugerindo que uma releitura atenta a esses dois elementos permite melhor compreensão de sua obra. Para Furtado, o excedente é o ponto de partida para uma apreensão mais ampla do desenvolvimento, uma vez que possibilita escolha por parte da comunidade e processos de transformação social. Seus primeiros trabalhos sobre desenvolvimento e subdesenvolvimento já insistem na interconexão entre excedente e estrutura social na definição dos modos de vida e do processo de acumulação. Sua abordagem das relações entre excedente e estruturas sociais ganha novos contornos nos anos 1970, levando em conta as transformações na economia internacional e a industrialização periférica. A interação entre pensamento econômico, cultural e político dá novos contornos à noção de excedente. O artigo se detém nos usos e significado da noção de excedente no pensamento de Furtado em seus diversos momentos.
The cultural sector’s productive chain in Brazil: estimation and structural change from 2011 to 2015
Authors: Morrone Henrique , Valiati Leandro
Published: May 2020

Abstract The objective of this article is to estimate the productive chain of the cultural sector in the Brazilian economy between the years 2011 and 2015 and to evaluate its structural change throughout this period. We estimated the input-output matrices for the years 2011 and 2015 using the methodology developed by Guilhoto and Sesso (2005). The method developed by Dietzenbacher et al. (2005) was applied in order to detect the productive chain and its evolution during this period. The results indicate that the cultural productive chain expanded during this period, incorporating new connections and contributing positively to the Brazilian economy. The cultural sector was classified as a net user of inputs from the rest of the economy. It showed strong direct and indirect backward linkages, purchasing intermediary inputs from many activities. Within the cultural sector, the artistic, creative and entertainment activities were highlighted.
A politização do conceito de cultura na teoria institucionalista: Thorstein Veblen e os antropólogos de sua época
Authors: Claudino Livio Sergio Dias
Published: May 2020

Resumo O conceito de cultura foi fundamental para o desenvolvimento das ciências sociais e humanas nos séculos XIX e XX. Também está na raiz da escola de pensamento econômico conhecida como Institucionalismo Americano, que teve como precursor Thorstein Veblen (1857-1929). Por meio da leitura de textos clássicos e revisão de literatura, o objetivo deste texto é apresentar o “pensamento antropológico” contemporâneo a Veblen, principalmente em torno do conceito de cultura e do método em Antropologia nos seus primórdios, e discutir as relações interdisciplinares que dão origem à escola de pensamento institucionalista, explicando a retomada da abordagem vebleniana nos últimos anos, especialmente nos estudos sobre consumo. Como principais resultados, destaca-se que Veblen valeu-se de instrumentos investigativos similares, estabelecendo diálogo com os escritos dos etnólogos e inﬂuenciando outros, tendo encaminhado o entendimento sobre cultura, principalmente por meio da crítica à “alta cultura”, os quais marcaram a noção de cultura na história do Institucionalismo Americano.

SUMMARY OBJECTIVE The current study aimed to examine the body composition of adult male ultra-trail runners (UTR) according to their level of participation (regional UTR-R, vs. national UTR-N). METHODS The sample was composed of 44 adult male UTR (aged 36.5±7.2 years; UTR-R: n=25; UTR-N: n=19). Body composition was assessed by air displacement plethysmography, bioelectrical impedance, and dual-energy X-ray absorptiometry. In addition, the Food Frequency Questionnaire (FFQ) was applied. A comparison between the groups was performed using independent samples t-test. RESULTS Significant differences between groups contrasting in the competitive level were found for chronological age (in years; UTR-R: 38.8±8.2 vs. UTR-N: 33.5±4.1); body density (in L.kg-1; UTR-R: 1.062±0.015 vs. UTR-N: 1.074±0.009); and fat mass (in kg; UTR-R: 12.7±6.8 vs. UTR-N: 7.6±2.7). CONCLUSION UTR-N were younger, presented higher values for body density, and had less fat mass, although no significant differences were found for fat-free mass. The current study evidenced the profile of long-distance runners and the need for weight management programs to regulate body composition.
Amor, riesgo y Sida: hombres que tienen sexo con hombres

Resumen: Se buscó comprender las condiciones en las cuales los hombres que tienen sexo con hombres se arriesgan a contraer el virus que produce el SIDA, en investigación de enfoque cualitativo con teoría fundada, a partir de entrevistas a hombres con relaciones homosexuales y conocimientos sobre el SIDA. Se encontró la homosexualidad como conducta reprochable, cuyo castigo es adquirir el virus que produce el SIDA. El conocimiento sobre la enfermedad no produce la evitación de las conductas de riesgo; pues, al buscar relacionarse con otro, se asume el riesgo. Se concluye que la unión de las carencias afectivas y la discriminación propicia una sobrevaloración de los encuentros de pareja; el afecto allí vivido se equipara al reconocimiento de un ser humano que es legitimado por otro.
Parto “natural” e/ou “humanizado”? Uma reflexão a partir da classe
Authors: Giacomini Sonia Maria , Hirsch Olívia Nogueira
Published: May 2020

Resumo: A “humanização” da assistência ao parto vem se difundindo no Brasil nas últimas décadas, tendo se disseminado principalmente nas camadas médias urbanas. Através de sua incorporação ao sistema público de saúde, a proposta foi estendida também a mulheres de camadas populares, o que vem colocando alguns desafios e gerado questionamentos, sobretudo ao formato que tem assumido a assistência “humanizada” nas instituições públicas. A partir da análise de duas situações vivenciadas por mulheres de diferentes classes sociais (uma no setor público e outra no privado), o artigo busca refletir acerca das noções de parto “natural” e de parto “humanizado”, apontando como se configuram, em cada um desses contextos, diferentes percepções sobre “humanização” e, em decorrência, também sobre o que seria seu oposto: a “violência obstétrica”.

Abstract The aim of this study was to verify and compare handgrip strength (HS) with activities of the daily living (ADL) and to identify the cutoff point of HGS in the prediction of independence in ADL of centenarians. Twenty-four centenarians with mean age of 101.67 ± 2.80 years participated in the study. Subjects were asked about marital status, schooling (years), diseases, hearing difficulties and activities of the daily living (Katz scale), to classify functional independence. Handgrip strength of the right hand (HSR) and left hand (HSL) (mean of the three measures of each hand) was evaluated by means of manual dynamometer. The U Mann Whitney test was applied to compare HSR and HSL with functions of ADL. To identify the cutoff point (sensitivity and specificity) of the right and left HGS of centenarians in the prediction of independence in functions of ADL, the Received Operating Characteristic (ROC) Curves were used. The following cutoff points were used: 11 Kgf for HSR (sensitivity = 66.7%, specificity = 100%, ROC curve = 0.778) and 9 Kgf for HSL (sensitivity = 66.7%, specificity = 77.8%, curve ROC = 0.730) to predict independence in performing the "bathing" function; 11 Kgf for HSR for the "continence" function (sensitivity = 83.3%, specificity = 66.7%, ROC curve = 0.712); and 9 Kgf for HSL for "transfer" function (sensitivity = 80%, specificity = 71.4%, ROC curve = 0.786). For these functions, sensitivity and specificity presented values greater than 66%. On all these functions, sensitivity showed values higher than 46% and specificity 77%. Minimum HSR is required to perform functions of ADL independently. The best HSR cutoff point to predict independence of subjects differs according to functions of activities of the daily living and hand evaluated.

Abstract Anthropometry is considered a widely applicable and effective method to track adiposity. Among the current methods of anthropometric analysis are the Body Mass Index (BMI) and the Waist Hip Index (ICQ) are utilized. However, both presents limitations because they fail to estimate the adiposity. In this sense, recently the Body Adiposity Index (IAC) emerged as an important tool in the adipose mass evaluation of large populations. Thus, the present study aimed to evaluate adults aged between 18 and 50 years through BMI, IAC and ICQ and to analyze the agreement degree between the methods. A total of 2602 individuals were analyzed, of which 1457 were women and 1145 men. After analyzing the data, it was verified that the majority of the population are within the standards of men was classified as not overweight only for ICQ and women for BMI and ICQ. In contrast the population of men is classified as healthy only for ICQ and women for BMI and ICQ. Concerning the agreement between the methods, only a positive and significant agreement between BMI and IAC was observed. Therefore, it can be concluded that IAC is an alternative for assessing body composition, showing a good method to estimate the percentage of total body fat of men and women, thus increasing the possibilities of diagnosis of obesity and overweight.

Abstract The study aimed to analyze the core tactical offensive principles and technical efficiency of primary school futsal players. Thirty-three students from a school in Paraná participated in the study. The System of Tactical Assessment in Soccer (FUT-SAT) and the System of Notational Analysis in Small-sided Soccer Games were used for tactical-technical analysis. It was found that the tactical principle “offensive coverage" was most frequently executed by the primary school futsal players (p = 0.01), followed by "width and length" without ball (p < 0.01). Moderate and strong significant correlations were identified between the execution frequency of the core tactical principles “penetration”, “offensive coverage”, “width and length without ball”, “offensive unity” and efficiency in technical skills (from r = 0.43 to r = 0.82, p < 0.05). It is concluded that there is a model of playing near the game center in the presented age group, and that the efficiency of executing technical skills is associated with tactical behavior in game situation.

Abstract The study analyzed the physical conditioning and the time of recovery of the maximum heart rate of 12 international referees being used the test of 20 meters with beep to evaluate the cardiorespiratory conditioning, with the frequency to control the recovery time of the maximum cardiac post test. The majority of the referees obtained a recovery of heart rate greater than 50% in 3 minutes, were those that reached the levels of good to excellent in the table of maximum Vo2. Even with some factors influencing their physical performance most of the referees were able to complete the aerobic test and obtained a good recovery of the heart rate, the others that failed to reach the test goal had the HR recovery in 3 minutes much lower than expected, thus highlighting the association of the maximum VO2 level between good and excellent with the recovery of the heart frequency.

Abstract Intense physical activity can increase oxidative stress and muscle damage in, causing fatigue and injury. Graduated compression stockings (GCS) can decrease these deleterious effects. The aim was to determine the acute effects of GCS on muscle damage and oxidative stress (OS) in garbage collectors. Thirteen garbage collectors, 25.4±5.2 years, participated using GCS or placebo stockings. Blood samples were collected at pre and post a working day and after 16 hours of rest. Markers of OS and muscle damage were evaluated. Two-way ANOVA (two conditions and two moments) was used for the analysis of the outcomes No significant differences were found for creatine kinase, catalase and glutathione peroxidase between the time and groups. There was a significant difference for the total thiol content and superoxide dismutase only in the control group (pre and post, p = 0.004). The use of GCS exerted acute protection against the increase of markers of OS, but did not contribute to attenuate muscle damage.

Published: May 2020

Resumo O treinamento funcional (TF) tem crescido em popularidade, porém tal crescimento ainda ocorre de forma desorganizada e multifacetada. Assim, uma atualização conceitual se faz necessário, especialmente, baseado na maneira como o TF tem sido aplicado na maioria das pesquisas. Nesse contexto, o TF tem sido compreendido como aquele que objetiva o aprimoramento sinérgico, integrado e equilibrado de diferentes capacidades físicas para garantir eficiência e segurança durante o desempenho de tarefas cotidianas, sendo baseado nos princípios do treinamento, sobretudo, no princípio da especificidade. As sessões de TF devem focar no aprimoramento de padrões básicos de movimento, estimular adequadamente a força em diversas situações, a potência muscular e a capacidade cardiorrespiratória, ativar frequentemente músculos estabilizadores e incluir atividades complexas, respeitando critérios de segurança e eficácia.

RESUMO Percebe-se uma oportunidade para melhor entender a inteligência informacional ao discuti-la no contexto acadêmico, de tal forma, o presente estudo teve como objetivo analisar as relações da inteligência informacional com os aspectos de hipercultura de estudantes universitários. Na sociedade da informação destacam-se os aspectos da cultura digital e da cibercultura; impulsionadas pelo desenvolvimento das tecnologias da informação e comunicação possuem como consequências a hipercultura, que serve de premissa para a teoria da mediação cognitiva (TMC) que articula a relação entre cognição, sociedade e tecnologia, auxiliando no entendimento dos impactos desses na cognição dos indivíduos. Para tanto, desenvolve-se o marco teórico apoiado nos entendimentos sobre inteligência informacional, teoria da mediação cognitiva e hipercultura. Metodologicamente a pesquisa possui abordagem quantitativa, utilizando questionário para coleta dos dados. Na análise e interpretação dos dados foram utilizados métodos estatísticos diversos. A população era composta por 1077 discentes matriculados no segundo semestre de 2017do curso de Administração da UFPE. A amostra foi não probabilística, por conveniência e estratificada, tendo participado 347 sujeitos. Os resultados da pesquisa revelaram que a inteligência informacional possui uma alta correlação com a hipercultura, essa correlação corrobora na direção que à luz da teoria da mediação cognitiva a inteligência informacional seja um elemento essencial da hipercultura.
