Why Do People Exercise in Natural Environments? Norwegian Adults’ Motives for Nature-, Gym-, and Sports-Based Exercise
Authors: Calogiuri Giovanna , Elliott Lewis
Published: April 2017

Exercise in natural environments (“green exercise”) confers numerous health benefits, but little is known about why people engage in green exercise. This study examined the importance of nature experiences as a motive for physical activity and the motivational profile of people who engage in green exercise compared to gym- and sports-based exercise. Physical activity motives and typical times spent in different domains of physical activity were reported by 2168 Norwegian adults in a survey. Experiencing nature was generally rated as the second-most important physical activity motive, exceeded only by convenience motives, and it was especially important for older adults and those who engage in greater amounts of instrumental physical activity. Green exercisers reported stronger motives concerning convenience and experiencing nature, whereas gym- or sports-based exercisers reported stronger motives for physical health and sociability. The motives associated with different leisure-time exercise domains may assist in understanding optimal promotion of green exercise.
Post-Colonization Interval Estimates Using Multi-Species Calliphoridae Larval Masses and Spatially Distinct Temperature Data Sets: A Case Study
Authors: Weatherbee Courtney R. , Pechal Jennifer L. , Stamper Trevor , Benbow M. Eric
Published: April 2017

Common forensic entomology practice has been to collect the largest Diptera larvae from a scene and use published developmental data, with temperature data from the nearest weather station, to estimate larval development time and post-colonization intervals (PCIs). To evaluate the accuracy of PCI estimates among Calliphoridae species and spatially distinct temperature sources, larval communities and ambient air temperature were collected at replicate swine carcasses (N = 6) throughout decomposition. Expected accumulated degree hours (ADH) associated with Cochliomyia macellaria and Phormia regina third instars (presence and length) were calculated using published developmental data sets. Actual ADH ranges were calculated using temperatures recorded from multiple sources at varying distances (0.90 m–7.61 km) from the study carcasses: individual temperature loggers at each carcass, a local weather station, and a regional weather station. Third instars greatly varied in length and abundance. The expected ADH range for each species successfully encompassed the average actual ADH for each temperature source, but overall under-represented the range. For both calliphorid species, weather station data were associated with more accurate PCI estimates than temperature loggers associated with each carcass. These results provide an important step towards improving entomological evidence collection and analysis techniques, and developing forensic error rates.
Mass Release of Trichogramma evanescens and T. cacoeciae Can Reduce Damage by the Apple Codling Moth Cydia pomonella in Organic Orchards under Pheromone Disruption
Authors: Sigsgaard Lene , Herz Annette , Korsgaard Maren , Wührer Bernd
Published: April 2017

Cydia pomonella is a major pest in apples in Denmark. Trichogramma spp. are known biocontrol agents of C. pomonella eggs and two naturally occurring species in Denmark, which are also both commercially available, were chosen for mass-release trials. Trichogramma evanescens, T. cacoeciae or a mix of the two species were evaluated for mass-release to control C. pomonella in two commercial organic apple orchards, one in 2012 and one in 2013, using a complete randomized block design. Pheromone disruption was used in both orchards, making the study one of the first to evaluate Trichogramma release under a mating disruption regime. Trichogramma activity was assessed using bait cards with Sitotroga cerealella eggs. The percent C. pomonella damaged fruit was recorded and the fruit yield was estimated. In 2012 cool and wet weather conditions resulted in low Trichogramma activity (<16% bait cards parasitized) and only T. evanescens was recovered from bait cards. The conditions in 2013 were warmer but T. evanescens was still >10 times more frequently found in bait cards than T. cacoeciae. There was a significant effect of the treatment and year (p = 0.009) and of the sampling period (p = 0.0008) on Trichogramma activity (proportion bait cards parasitized), with no significant difference between treatments in 2012. In 2013 the highest activity was found in T. evanescens and mixed treatments, in July reaching 69% and 47% bait cards parasitized, respectively. Fruit damage was highest in the control plots (7.1%) compared with Trichogramma treatments (T. evanescens 2.8%, T. cacoeciae 3.8%, mixed 3.3%) (p = 0.028). Yield did not differ significantly between treatments. In conclusion, Trichogramma mass release is a promising biocontrol method for use in the Danish climate, but further studies are needed regarding the performance of the two Trichogramma species (and potential other Trichogramma species) towards C. pomonella eggs in the field to identify the best biocontrol candidate.

We present a case of severe adenoviral pneumonia in a 20-year-old immunocompetent host with persistently high fevers. The patient was needlessly given multiple empiric antibiotics for non-existent bacterial co-infection. This case has important antibiotic stewardship lessons for practitioners in approaching fevers in the ICU.
Microstructural Characteristics and Mechanical Properties of 2205/AZ31B Laminates Fabricated by Explosive Welding
Authors: Li Yan , Wu Zhisheng
Published: April 2017

A bimetal composite of 2205 duplex stainless steel and AZ31B magnesium alloy was cladded successfully through the method of explosive welding. The microstructural characteristics and mechanical properties of 2205/AZ31B bimetal composite are discussed. The interface of 2205/AZ31B bimetallic composite was a less regular wavy morphology with locally melted pockets. Adiabatic shear bands occurred only in the AZ31B side near explosive welding interface. The microstructure observed with EBSD showed a strong refinement near the interface zones. Line scan confirmed that the interface had a short element diffusion zone which would contribute to the metallurgical bonding between 2205 duplex stainless steel and AZ31B magnesium alloy. The value of micro-hardness near the bonding interface of composite plate increased because of work hardening and grain refinement. The tensile shear strength of bonding interface of 2205/AZ31B composite was 105.63 MPa. Tensile strength of 2205/AZ31B composite material was higher than the base AZ31B. There were two abrupt drops in stress in the stress–strain curves of the 2205/AZ31B composite materials.

Published: April 2017

The paper presents test results for the mechanical and creep properties of European aluminium alloy EN 6082AW T6 at high temperatures. Mechanical properties of the aluminium alloy were determined by means of two types of test: constant stress-rate and stationary creep tests. Mechanical properties were determined up to a temperature of 350 °C, while the creep tests were conducted within the temperature interval 150–300 °C. The creep tests conducted identified the critical temperature interval for creep development, which represents an important factor when analysing creep behaviour of aluminium structures. This temperature interval was found to be within the range 200–300 °C. Test results for stress at 0.2% strain and modulus of elasticity at different temperatures showed good agreement with the codified values from Eurocode 9 and with other comparable studies.

Published: April 2017

The rational design of quinones with specific redox properties is an issue of great interest because of their applications in pharmaceutical and material sciences. In this work, the electrochemical behavior of a series of four p-quinones was studied experimentally and theoretically. The first and second one-electron reduction potentials of the quinones were determined using cyclic voltammetry and correlated with those calculated by density functional theory (DFT) using three different functionals, BHandHLYP, M06-2x and PBE0. The differences among the experimental reduction potentials were explained in terms of structural effects on the stabilities of the formed species. DFT calculations accurately reproduced the first one-electron experimental reduction potentials with R2 higher than 0.94. The BHandHLYP functional presented the best fit to the experimental values (R2 = 0.957), followed by M06-2x (R2 = 0.947) and PBE0 (R2 = 0.942).
The Spiral Structure of Marshall McLuhan’s Thinking
Authors: Pruska Oldenhof Izabella , Logan Robert
Published: April 2017

We examine the spiral structure of the thinking and the work of Marshall McLuhan, which we believe will provide a new way of viewing McLuhan’s work. In particular, we believe that the way he reversed figure and ground, reversed content and medium, reversed cause and effect, and the relationship he established between the content of a new medium and the older media it obsolesced all contain a spiral structure going back and forth in time. Finally, the time structure of his Laws of Media in which a new medium obsolesced an older medium, while retrieving an even older medium and then when pushed far enough flipped into a still newer medium has the feeling of a spiral. We will also examine the spiral structure of the thinking and work of those thinkers and artists that most influenced McLuhan such as Vico, Hegel, Marx, Freud, Joyce, TS Eliot, Wyndham Lewis and the Vorticism movement.
Power MOSFET Linearizer of a High-Voltage Power Amplifier for High-Frequency Pulse-Echo Instrumentation
Authors: Choi Hojong , Woo Park , Yeom Jung-Yeol , Yoon Changhan
Published: April 2017

A power MOSFET linearizer is proposed for a high-voltage power amplifier (HVPA) used in high-frequency pulse-echo instrumentation. The power MOSFET linearizer is composed of a DC bias-controlled series power MOSFET shunt with parallel inductors and capacitors. The proposed scheme is designed to improve the gain deviation characteristics of the HVPA at higher input powers. By controlling the MOSFET bias voltage in the linearizer, the gain reduction into the HVPA was compensated, thereby reducing the echo harmonic distortion components generated by the ultrasonic transducers. In order to verify the performance improvement of the HVPA implementing the power MOSFET linearizer, we measured and found that the gain deviation of the power MOSFET linearizer integrated with HVPA under 10 V DC bias voltage was reduced (−1.8 and −0.96 dB, respectively) compared to that of the HVPA without the power MOSFET linearizer (−2.95 and −3.0 dB, respectively) when 70 and 80 MHz, three-cycle, and 26 dBm input pulse waveforms are applied, respectively. The input 1-dB compression point (an index of linearity) of the HVPA with power MOSFET linearizer (24.17 and 26.19 dBm at 70 and 80 MHz, respectively) at 10 V DC bias voltage was increased compared to that of HVPA without the power MOSFET linearizer (22.03 and 22.13 dBm at 70 and 80 MHz, respectively). To further verify the reduction of the echo harmonic distortion components generated by the ultrasonic transducers, the pulse-echo responses in the pulse-echo instrumentation were compared when using HVPA with and without the power MOSFET linearizer. When three-cycle 26 dBm input power was applied, the second, third, fourth, and fifth harmonic distortion components of a 75 MHz transducer driven by the HVPA with power MOSFET linearizer (−48.34, −44.21, −48.34, and −46.56 dB, respectively) were lower than that of the HVPA without the power MOSFET linearizer (−45.61, −41.57, −45.01, and −45.51 dB, respectively). When five-cycle 20 dBm input power was applied, the second, third, fourth, and fifth harmonic distortions of the HVPA with the power MOSFET linearizer (−41.54, −41.80, −48.86, and −46.27 dB, respectively) were also lower than that of the HVPA without the power MOSFET linearizer (−25.85, −43.56, −49.04, and −49.24 dB, respectively). Therefore, we conclude that the power MOSFET linearizer could reduce gain deviation of the HVPA, thus reducing the echo signal harmonic distortions generated by the high-frequency ultrasonic transducers in pulse-echo instrumentation.
Optimum Design Rules for CMOS Hall Sensors
Authors: Crescentini Marco , Biondi Michele , Romani Aldo , Tartagni Marco , Sangiorgi Enrico
Published: April 2017

This manuscript analyzes the effects of design parameters, such as aspect ratio, doping concentration and bias, on the performance of a general CMOS Hall sensor, with insight on current-related sensitivity, power consumption, and bandwidth. The article focuses on rectangular-shaped Hall probes since this is the most general geometry leading to shape-independent results. The devices are analyzed by means of 3D-TCAD simulations embedding galvanomagnetic transport model, which takes into account the Lorentz force acting on carriers due to a magnetic field. Simulation results define a set of trade-offs and design rules that can be used by electronic designers to conceive their own Hall probes.
Enhancement of MCF Rubber Utilizing Electric and Magnetic Fields, and Clarification of Electrolytic Polymerization
Authors: Shimada Kunio
Published: April 2017

Many sensors require mechanical durability to resist immense or impulsive pressure and large elasticity, so that they can be installed in or assimilated into the outer layer of artificial skin on robots. Given these demanding requirements, we adopted natural rubber (NR-latex) and developed a new method (NM) for curing NR-latex by the application of a magnetic field under electrolytic polymerization. The aim of the present work is to clarify the new manufacturing process for NR-latex embedded with magnetic compound fluid (MCF) as a conductive filler, and the contribution of the optimization of the new process for sensor. We first clarify the effect of the magnetic field on the enhancement of the NR-latex MCF rubber created by the alignment of magnetic clusters of MCF. Next, SEM, XRD, Raman spectroscopy, and XPS are used for morphological and microscopic observation of the electrolytically polymerized MCF rubber, and a chemical approach measuring pH and ORP of the MCF rubber liquid was used to investigate the process of electrolytic polymerization with a physical mode. We elucidate why the MCF rubber produced by the NM is enhanced with high sensitivity and long-term stability. This process of producing MCF rubber by the NM is closely related to the development of a highly sensitive sensor.
Self-Concept in Adolescents—Relationship between Sport Participation, Motor Performance and Personality Traits
Authors: Klein Markus , Fröhlich Michael , Emrich Eike
Published: April 2017

The relationship between sport participation, personality development, self-concept and self-esteem has been discussed repeatedly. In this research, a standardized written survey together with tests on motor performance were carried out with 1399 students (707 male; 692 female) in school years 7 (12.9 ± 0.6 years) and 10 (15.8 ± 0.6 years) to measure the extent of a relationship between physical self-concept (self-developed short scale) and sporting activity, measured motor performance (German motor performance test DMT (Deutscher Motorik-Test) 6–18) and report mark in physical education. Relationships were also analyzed between physical self-concept and general personality traits (neuroticism, extraversion, openness to experiences, compatibility, and conscientiousness, measured with NEO Five Factor Inventory (NEO-FFI)). The assessment of own physical attractiveness and own athleticism differs by sex (F(1, 962) = 35.21; p < 0.001), whereby girls assess themselves more critically. Weak significant relationships are displayed between motor performance and the assessment of own physical attractiveness (r(395) = 0.31; p < 0.01). Motor performance is given a higher predictive value with regard to a subject’s own self-concept, (physical attractiveness β = 0.37; t(249) = 5.24; p < 0.001; athleticism β = 0.40; t(248) = 6.81; p < 0.001) than the mark achieved in physical education (physical attractiveness β = −0.01; n.s.; athleticism β = −0.30; t(248) = 5.10; p < 0.001). Relationships were found overall between personality traits and physical self-concept. The influence of the ‘neuroticism’ trait is particularly strong (physical attractiveness β = −0.44; t(947) = −13.58; p < 0.001; athleticism β = −0.27; t(948) = −7.84; p < 0.001). The more pronounced this trait, the lower the assessment of own physical attractiveness and own athleticism.
Global Interdependence of Collaborative R&D-Typology and Association of International Co-Patenting
Authors: Su Hsin-Ning
Published: April 2017

Economic globalization implies a growing interdependence of resources across countries. Technological R&D and cross-border collaboration are often identified as the primary driving forces in the process. This study aims to holistically analyze global landscape of international collaboration and identify influential countries and the interdependencies among countries. A total of 458,381 international patents granted by the United States Patent and Trademark Office (USPTO) from 1976 to 2013 are analyzed and the structure of international collaboration network is created. It is found that highly developed and small countries usually show a higher degree of internationalization. However, emerging countries such as China present high collaborative influences. The highly skewed collaboration distribution indicates significant inequality of internationalization, which is indeed a hurdle to a country’s technological mobility. It can be observed that most pairs of interdependent countries are neighboring or even bordering countries because of their similar historical, linguistic and cultural heritages. Several contributions of this study are summarized as follows: (1) this study first proposes the II, IA, II-IA, IA-AA, and II-IA-AA system for classifying international patent; (2) all international patents (38-year time span) from USPTO are examined without sampling; (3) association rule mining is used to evaluate the interdependency of international collaboration; and (4) network structures illustrating 38 years international co-patenting are visually presented.
A Study on User-Oriented and Intelligent Service Design in Sustainable Computing: A Case of Shipbuilding Industry Safety
Authors: Joe Taehee , Chang Hangbae
Published: April 2017

Most business services based on Ubiquitous Computing are being designed with a sole focus on the technological sector, without considering business elements. In light of this trend, this study was intended to design a user-oriented u-Business service for preventing and promptly responding to industrial disasters at shipbuilding sites using a systematic methodology. Specifically, major danger elements of disasters in need of preferential preventive and responsive measures were derived as business opportunities unfulfilled by the current process, and then a u-Business service was developed to prevent/respond to such dangers. Statistical analysis was performed on the developed services according to evaluation models, and the final u-Business service was selected based on this analysis. Resources and information systems were designed to support the chosen service.

Fonctionnement hydrologique superficiel de la Réserve naturelle nationale du Marais de Lavours
Authors: Jézéquel Céline
Published: April 2017

Le gestionnaire de la réserve naturelle assiste depuis la fin des années quatre-vingts à un assèchement de certaines parties du marais. Pour mieux appréhender les processus écologiques en cours, une meilleure connaissance du fonctionnement hydrologique est nécessaire. Une campagne de prospection des fossés a permis la réactualisation de la cartographie du réseau de drainage, de dégager une vision dynamique des circulations hydrauliques superficielles et de délimiter les masses d'eau en présence. L'évolution du réseau de drains est représentée grâce à l'analyse de plusieurs cartes anciennes. Le tassement de la tourbe au cours du temps est estimé par la comparaison de cotes d'altitude anciennes et récentes sur certaines zones du marais. L'ensemble des résultats montre l'impact important des aménagements récents sur l'assèchement de la tourbière, que ce soit à l'échelle du marais (fossés, vannes) ou à plus grande échelle (canalisation du Rhône). La mise en évidence des processus hydrologiques en cours dans la réserve peut guider le gestionnaire dans ses actions pour préserver ce milieu.
Évolution de la végétation du marais de Lavours (Ain, France) à quarante-cinq ans d'intervalle (1967-2012)
Authors: Mikolajczak Alexis , Darinot Fabrice
Published: April 2017

Evolution of the Lavours marsh vegetation with a forty-five years interval (1967-2012). - Vegetation maps of the Lavours marsh realized 45 years apart are compared. The main changes in vegetal landscape and land use include : (i) transformation into crop fields of large surfaces of wet meadows, (ii) the spontaneous or chosen development of forest and (iii) the development of an open eutrophic vegetation, due to the water table lowering and the subsequent nutrient enrichment of habitats on silt substrate. In this context, the Réserve naturelle nationale du Marais de Lavours plays a major role for open habitats conservation on peat soils, which have almost disappeared in the rest of the marsh. The situation of open habitats on silt substrate is more moderate because half of them are outside of the nature reserve, dispached in small unmanaged islands.
Evaluation des propriétés fourragères, agronomiques et calorifiques du foin de marais issu de la Réserve naturelle nationale du Marais de Lavours

Published: April 2017

Evaluation of fodder, agronomie and calorific properties of the Réserve naturelle nationale du Marais de Lavours (Ain) marsh hay. - Marsh hay, named «blache» in the French Haut-Rhône region, used to be an important resource for local people near the Lavours marsh. Today, Réserve naturelle nationale du Marais de Lavours managers have difficulties to value this marsh hay, as other wetlands managers. However, this study shows that the properties of marsh hay could give several valuations for this material. Its fodder value is suitable for cattle, even for lactating cows, but its lack of mineral elements should be compensated by a complementation. It could be transformed in a good compost with a strong amendment power ; however, marsh hay is better for co-compost in association with breeding effluents. Its calorific power is excellent and its low silica rate allows a weak fouling of burning chambers.
Réponse d'une cariçaie eutrophe au pastoralisme et résilience post-pâturage dans la Réserve naturelle nationale du Marais de Lavours (Ain, France)
Authors: Darinot Fabrice , Manneville Olivier
Published: April 2017

La Réserve naturelle nationale du Marais de Lavours (Ain) a mis en place un pâturage bovin et équin extensif en 1987 dans une cariçaie eutrophe à Carex elata, afin de restaurer la végétation qui s'embroussaillait à cause d'un abandon des pratiques traditionnelles. Cette expérience pastorale fut arrêtée après douze ans, car elle conduisait à une dégradation de la végétation. Le suivi de la végétation, initié dès 1986, s'est poursuivi pendant 22 ans et a permis de mettre en évidence des modifications importantes du peuplement pendant la période pâturée et après le retrait des troupeaux, en terme d'abondance relative des espèces mais non en terme de composition spécifique. Des hypothèses sont émises pour expliquer ces changements, en se basant sur la valeur fourragère de la végétation et sur la biologie des plantes. Cette étude met en évidence une évolution du peuplement initialement en équilibre vers un système en non-équilibre, qui perdure encore 10 ans après l'arrêt du pastoralisme.

Inventory of the saproxylic beetles in the Réserve naturelle nationale du Marais de Lavours (Coleoptera). - Forest beetles of the Réserve naturelle nationale du Marais de Lavours were inventoried by various techniques. 163 obligate saproxylic species were identified among 281 beetles taxa. Nine saproxylic species can be considered as patrimonial species thanks to their regional or national rarity or their classification as relict of ancient forest in Europe. The comparison of data obtained from standardized traps shows similarities between Qitercus-Fraxinus and young Almts stands. However, in detail, the canopy of the Quercus-Fraxinus has a rather unique fauna among the rest of the forest. The study of beetles living in canopy, as conduced in the reserve, is to be developed in temperate climate.

Inondation hivernale et mouvements migratoires au sein d'une population de rat des moissons, Micromys mmutus (Pallas, 1771)
Authors: Darinot Fabrice , Favier Camille
Published: April 2017

Le rat des moissons (Micromys minutus ), le plus petit rongeur d'Europe, est une espèce qui vit préférentiellement dans les zones humides, parfois soumises à des inondations. L'effet de telles perturbations naturelles sur les communautés de micromammifères en général et sur le rat des moissons en particulier est encore largement méconnu. Cette étude vise à mettre en évidence la recolonisation de l'habitat de ce rongeur dans la Réserve naturelle nationale du Marais de Lavours depuis une zone refuge restée hors d'eau pendant l'inondation de décembre 2011-janvier 2012. Les rats des moissons effectuent rapidement cette migration, en quatre jours pour les individus les plus rapides, sur une distance de 160 m. Les mâles semblent plus nombreux et plus mobiles que les femelles, qui sont pour la moitié déjà gestantes en début de migration. Les rats des moissons semblent peu affectés par la lame d'eau qui inonde l'habitat recolonisé, car ils sont capables de se déplacer en hauteur dans la magnocariçaie. Les mouvements observés confirment que cette espèce est bien adaptée aux zones humides, mais soulèvent également des interrogations sur la taille de leur domaine vital et sur le phénomène de retour au gîte.

As posturas são fatores que influenciam a estrutura óssea das pessoas, este estudo mostra a necessidade de uma boa postura, para o desenvolvimento de uma atividade vêm desde a antiguidade e chega aos dias atuais, exemplos de melhorias referenciado a Bernardino Ramazzini, sendo o primeiro a escrever sobre doenças ocupacionais, suas conseqüências para o organismo, mostrando ferramentas adequadas para cada atividade, gerando ganhos produtivos, com menores impactos para a saúde, segurança, para o corpo humano.A estrutura da coluna vertebral e o impacto quando levantamos ou movimentamos objetos, peso acima de 4 kg já é considerado elevado para a manipulação, podendo causar danos ao tecido muscular, apresenta uma ferramenta identificada como Equação de Levantamento Revisado do National Institute for Occupational Safety and Health (NIOSH), criado na década de 80 e revisado em 90, tendo como finalidade identificar critérios epidemiológicos, psicológicos, biomecânicos e fisiológico e encontrar condições para identificar o Limite de Peso Recomendável (LPR) para a atividade e assim identificar um Índice de Levantamento (IL) que é encontrado com a divisão da carga pelo LPR, chegando a um valor que define o risco de lesão ao trabalhador. Apresenta uma aplicação real, a atividade inicial, seus riscos, melhorias e o aumento no limite do peso a ser movimentado e a redução do risco de lesão por parte do trabalhador. Este trabalho mostra que em uma boa analise ergonômica podemos movimentar cargas mais pesadas e com menos riscos, ampliando a produtividade, reduzindo o absentismo e afastamentos decorrentes deste motivo.

O setor varejista engloba diversas subdivisões, entre elas, o setor de vestuário, que envolve variáveis como tendências de moda e sazonalidade, que influenciam diretamente na compra e venda dos produtos, e gera reflexos na tomada de decisões dentro da empresa e na gestão de estoques. Entretanto, muitas micro e pequenas empresas varejistas não possuem um sistema de informação com módulos decisórios ou ainda de um sistema de gestão de estoque. Dessa forma, o presente artigo objetivou apresentar uma proposta para a gestão de estoques por meio das ferramentas de controle de estoque em uma empresa varejista na cidade Ilhéus-BA de forma a garantir uma vantagem competitiva. A pesquisa se deu a partir do estudo do perfil da empresa e da coleta de dados, os quais foram tratados por meio do conjunto de ferramentas de controle de estoque: Curva ABC, Giro de Estoque e Diagrama de Pareto. Os resultados foram analisados de modo a estabelecer uma gestão de estoque que impactassem na estratégia competitiva de mercado. Percebeu-se que a falta de gestão contribuiu para acúmulo de alguns itens, depreciação dos produtos e também para má distribuição do capital da empresa. A elaboração de uma proposta de gestão de estoque pode contribuir para o desenvolvimento dessas micro e pequenas empresas varejistas, por meio de um melhor direcionamento e suporte, contribuindo também para uma maior taxa de sobrevivência, e consequentemente para o desenvolvimento econômico e social do país.

Published: April 2017

O Brasil é o terceiro maior mercado consumidor de cosméticos e produtos de beleza do mundo, e nos últimos anos o aumento da consciência ecológica dos consumidores foi evidenciado por pesquisas nacionais e internacionais. Nesse contexto, o objetivo da presente pesquisa foi o de identificar a preferência de consumidores de cosméticos por empresas ambientalmente sustentáveis, que aplicam práticas de logística reversa visando a sua fidelização. Para isso o estudo contou com uma análise documental, realizada com base em três indústrias de cosméticos brasileiras, e um questionário com perguntas abertas e fechadas, aplicado a 504 respondentes. Trata-se de uma pesquisa aplicada, descritiva, de abordagem quali-quantitativa, cujo procedimento técnico foi o survey. A pesquisa identificou as atividades desenvolvidas pelas empresas nas áreas de logística reversa e fidelização. Além disso, verificou a preferência dos consumidores por empresas que realizam a logística reversa de embalagens pós-consumo de forma a proporcionar vantagens aos consumidores que as retornem às lojas.

O objetivo do presente trabalho é analisar o nível da qualidade dos serviços de mobilidade urbana coletiva oferecida na interligação dos municípios Rio de Janeiro e Niterói através do modal aquaviário, através da identificação dos elementos que fazem diferença para o usuário na usabilidade do sistema. Durante o processo de pesquisa e diagnóstico foram identificados os elementos que fazem diferença para o usuário na usabilidade do referido sistema de transporte que representa uma alternativa ao modal rodoviário, predominante no país. O trabalho consiste nas etapas metodológicas estabelecidas na fase de planejamento e execução da pesquisa, com destaque para: a definição do campo, o objeto estudado, revisão da literatura, definição de critérios, coleta de dados, análise dos dados e informações conclusivas. A pesquisa é teórica e empírica, pois se fundamenta de uma revisão teórica, porém foi feita uma coleta de dados através de questionários aplicados diretamente aos usuários do sistema. O diagnóstico final do sistema constatou que os critérios que mais produzem impacto na percepção do usuário são a sua confiabilidade e seu custo direto, a tarifa, uma vez estabelecidos os padrões mínimos para todos os critérios, estes dois são os que se sobressaem na ótica do usuário e também os que recebem maior rigor no momento de sua avaliação, tal rigor refletiu como o pior desempenho na percepção dos usuários.

Published: April 2017

A competitividade no setor supermercadista é notória, sendo peremptório a busca de estratégias empresariais para se diferenciar no mercado. Uma das estratégias adotadas está pautada no desenvolvimento de relacionamento entre supermercados e cliente, por meio do marketing de relacionamento ou CRM (Customer Relationship Management). As recentes revisões da literatura sobre CRM deixam claro a importância do tema e apresenta um campo fértil para o desenvolvimento de instrumentos de gestão de relacionamento com clientes de supermercados. Portanto, o objetivo geral é desenvolver e validar um instrumento científico para avaliar a percepção dos clientes quanto ao seu relacionamento com os supermercados, com propósito de criar um diagnóstico para os gestores do setor supermercadista estabelecerem relacionamentos duradouros com seus clientes, tendo em vista que os resultados apresentam que os clientes têm percebido poucas iniciativas de CRM no setor. O estudo é multimétodo, e os resultados foram analisados por meio de análise de conteúdo categorial temática, e análise fatorial exploratória e confirmatória, por meio da modelagem por equações estruturais. A escala apresentou três fatores de primeira ordem e um fator de segunda ordem, apresentando validade interna, de conteúdo e confiabilidade.

Rasmussen (1979, 1983, 1986) a proposé le modèle cadre des habiletés, règles et connaissances (SRK). Si ce modèle est particulièrement influant dans la communauté des Facteurs Humains et Ergonomie, peu d’études empiriques ont tenté de le mettre à l’épreuve. Dans cet article, nous nous focalisons sur les prédictions de ce modèle envers la charge mentale. Elles suggèrent que le mode de contrôle produit des niveaux distincts et croissants de charge mentale. Pour tester cette prédiction nous avons réalisé une expérience auprès de quarante-quatre participants ayant à résoudre une version modifiée des tâches du MATB-II. Plus précisément, ils devaient réaliser trois tâches différentes illustrant chacune un niveau de contrôle fondé sur les habiletés, les règles ou les connaissances. Des indices physiologiques (cardiaques), des évaluations subjectives de la charge ainsi que des mesures de performance ont été recueillis. Les résultats sont conformes aux prédictions concernant les modes de contrôles liés aux habiletés et aux règles. Néanmoins, lorsque le mode était basé sur les connaissances, les participants obtenaient les moins bonnes performances et percevaient la charge mentale comme étant la plus faible. Nous interprétons ces résultats à la lumière d’études issues des neurosciences et distinguons l’engagement et l’effort. Nous notons que les participants ne se sont pas pleinement engagés dans la tâche, par un effort réduit et une performance plus faible que dans les autres tâches. Nous considérons alors que ce type de raffinement conceptuel de la charge mentale s’appuyant sur les neurosciences souligne l’intérêt de la neuro­ergonomie pour les Facteurs Humains et l’Ergonomie.
Towards real-time detection of cognitive effort in driving: contribution of a cardiac measurement

Published: April 2017

En 2013, on estime que 40 à 50 % des accidents corporels seraient dus à un défaut d’attention de la part du conducteur. Des travaux récents ont mis en évidence la possibilité de détecter des états attentionnels dégradés afin de pouvoir mieux assister le conducteur ; ce thème de recherche pourrait ouvrir la voie à de nouvelles perspectives en sécurité routière. Cette étude se concentre sur la détection de l’effort cognitif fourni par les conducteurs et cherche, par l’analyse de la variation du rythme cardiaque, à identifier un indicateur d’effort sensible sur de courtes fenêtres temporelles. Dix-huit conducteurs ont participé à l’étude. Ils ont été répartis dans 8 conditions expérimentales dans lesquelles ils devaient effectuer une tâche cognitive de manière passive (simple écoute) ou active (comptage) lors d’une session de conduite ou non. Le comptage présentait 2 niveaux de difficultés (comptage de bips vs addition de nombre à partir d’une tâche visuo-spatiale). Les rythmes cardiaques et leurs variations ont été collectés durant toutes les sessions. Au terme de notre étude, il s’avère qu’il est possible de distinguer des patterns cardiaques d’effort et de relaxation sur de courtes fenêtres temporelles en moyennant la variation du rythme cardiaque sur un nombre conséquent d’épisodes. L’indicateur d’effort cognitif, caractérisé par deux composantes cardiaques (ECR1 et ECR2) et identifié par plusieurs auteurs comme sensible dans des tâches de laboratoire, s’est montré aussi sensible en conduite automobile. En effet, dans les secondes qui suivent un effort cognitif, une légère décélération du rythme cardiaque puis une forte accélération ont été mises en évidence. A l’inverse, sans effort cognitif, une simple décélération cardiaque a été observée. Les résultats obtenus ont permis de montrer des accélérations cardiaques plus importantes lors d’une double tâche (comparée à une tâche simple) et lors d’une tâche cognitive difficile (comparée à une tâche cognitive facile). Ces résultats laissent supposer qu’un indicateur quantitatif de l’effort cognitif pourrait être approché par l’étude de la variation du rythme cardiaque en conduite automobile. Dans l’objectif de développer des systèmes capables de détecter en temps réel un effort cognitif important, les dispositifs devront être capables de visualiser l’effort sur un unique évènement. Explorer la faisabilité de la suppression de l’influence de la respiration sur le rythme cardiaque pourrait améliorer la sensibilité de l’indicateur en question. Si cela s’avère réalisable et si la correction effectuée permet de mieux détecter l’effort cognitif en temps réel, des assistances adaptatives pourraient alors alerter le conducteur ou pallier ses erreurs lorsque celui-ci ne peut plus assurer la tâche de conduite en raison d’un effort cognitif important.
