O crescimento do mundo virtual impacta diversos aspectos da vida social. Como desdobramento, o método de pesquisa chamado de Netnografia (Kozinets, 1998), uma adaptação do método etnográfico para o mundo virtual, também vem despertando cada vez mais o interesse de pesquisadores e apresentando excelentes resultados em estudos acadêmicos Por exemplo, a utilização do método já pode ser vista em algumas disciplinas como ciências da saúde (ERIKSSON E ERIKSSON, 2013), educação (FERREIRA; DA SILVA, 2014), estudos da religião (LOVE, 2011), turismo (MKONO, 2011), entre outras. Entretanto, apesar do reconhecimento de diversas áreas do conhecimento de que o crescimento do mundo virtual tem impactos em diversos aspectos da vida contemporânea e das potencialidades do uso metodológico da netnografia, nota-se a predominância de seu uso na investigação de fenômenos apenas na área de Marketing (BRENGRY-HOWEEL et al, 2011), ainda não parecendo gozar de muita popularidade em outras áreas da Administração. Desta forma, o objetivo do presente artigo é apresentar os pressupostos da netnografia e do método de análise de discurso adaptado para o mundo virtual, a Análise de Discurso Mediada por Computador (ADMC), considerando as suas possibilidades de uso e suas contribuições para a pesquisa na área da Administração.

Pesquisa qualitativa ou qualidade em pesquisa? Um exemplo de contribuição sócio-humanista em pesquisa contábil
Authors: Silva Sandra Maria Cerqueira da , Nova Silvia Pereira de Castro Casa
Published: March 2018

Flick (2009) afirma que abordagens qualitativas de pesquisa têm vivido um período de crescimento e diversificação inéditos, tornando-se uma proposta de pesquisa consolidada e respeitada em diversas disciplinas e contextos. Um dos paradigmas de pesquisa alinhado com as abordagens qualitativas é o pós-estruturalismo, que entende a realidade como uma construção social e subjetiva, propondo uma desconstrução de textos entendidos como uma decomposição dos elementos da escrita, para descobrir as partes que estejam dissimuladas e que impeçam a alteração de condutas. Haynes (2010) aponta a história oral, apoiadas em entrevistas em profundidade, como uma excelente fonte para construção de evidências, sendo particularmente rica e poderosa para explorar a experiência daquelas que foram marginalizadas, silenciadas ou ignoradas no contexto contábil. Para reposicionar a relevância que abordagens qualitativas de pesquisa têm ganhado na contabilidade apresentaremos um exemplo de uma pesquisa desenvolvida a partir de histórias orais de acadêmicas brasileiras. A pesquisa em tela busca auxiliar na tarefa de identificar se existe alguma diferença na forma como as mulheres contabilistas exercem sua profissão e performam seu gênero diante da perspectiva da maternidade, analisando a relação entre o corpo, a autoimagem e os requisitos de apresentação para as mulheres profissionais de contabilidade. Haynes (2008) argumenta como o corpo se torna um veículo para a exibição de conformidade – ou, na verdade, não-conformidade – às normas sociais, o que afeta as práticas incorporadas, emoções e identidades. Para Lehman (2012), políticas econômicas e sociais estão intimamente atadas, portanto, a necessidade de modificar a condição da mulher – e similarmente, de mudar as perspectivas sobre sua contribuição para a contabilidade, como o desenvolvimento de métodos que deem visibilidade, adotando novos conceitos que revelem aspectos que têm sido silenciados como conceitos de valor, valorização ou valoração do trabalho, risco e poder.

La ciencia es a menudo acumulativa, es decir, para construir los instrumentos más poderosos, efectúan medidas más exactas, precisan de mejores y más amplios conceptos de las teorías, y así sucesivamente. Si bien los paradigmas pueden cambiar, las investigaciones suelen evolucionar en función del rendimiento pasado, lo que constituye una justificación para un mayor desarrollo. El científico estará más seguro en su investigación y mejor preparado para nuevos retos si sabe cómo su tema, en particular, ha evolucionado históricamente, cuáles fueron sus principales dificultades, las soluciones encontradas y los problemas pendientes.

Authors: Borrero-Guerrero Henry , Bueno-Sampaio Rafael , Becker Marcelo
Published: March 2018

This paper presents the preliminary studies of the control strategy based in fuzzy logic, projected for the steering system of AGRIBOT project that consist of a wheeled autonomous mobile robotic in real scale endowed with four independent steering and driven wheels (4WSD). In this work we present a preliminary fuzzy controller design applied to front steering angle, using a multivariable plant which incorporates simplified linear model of lateral dynamics of a vehicle whose input are linear combination of rear and front steering angles. The fuzzy control strategy was decided because provides flexible way to deploy with embedded systems. Simulations are used to illustrate the designed controller performance. We use Ackerman geometry to trace front steering angle that allows the vehicle to perform correctly a given maneuver preserving a minimum level of stability and maneuverability. The goal is to establish a relationship between steering input commands and the control commands to the actuators so that it is possible to adjust the attitude of the actuators over the movement axis, as the trajectory change.

Published: March 2018

The aim of study was to evaluate the chemical composition, including mineral content, in milk of different breeds maintained in organic and traditional farms using intensive (PMR) and traditional feeding systems. The study was carried out on 47 farms in south-eastern Poland. A total of 735 milk samples were analysed, including 263 from cows raised on organic farms, 218 from cows raised on conventional farms using a traditional feeding system, and 254 from cows raised on conventional farms using an intensive feeding system (PMR). All types of farms raised Polish Holstein-Friesian and Simmental cows, and the conventional farms using a traditional feeding system also kept Polish Red and White-Backed cows. The highest (p≤0.01) daily milk yield and content of protein, lactose, dry matter and urea in the milk were obtained from the cows fed in the PMR system. The highest fat content was noted for the milk from the conventional farms using a traditional feeding system. The animals raised in the organic system produced the least milk, with the lowest concentrations of its basic nutrients. The highest mineral content was noted for the milk from the traditional system. The milk from the organic system contained the least Ca, Na, Mg, Zn and Fe, while the milk from the intensive system contained the least Mn. The content of Cu was similar in the milk from the organic and intensive systems and lower (p≤0.01) than in the milk from the traditional system. The results of two-way analysis of variance indicate that the breed of cow significantly influenced milk yield, protein content, protein-to-fat ratio, Ca and Zn concentration (p≤0.01), and the content of dry matter, Fe and Mn in the milk (p≤0.05). .

Authors: Mahrouse Marianne Alphonse , El-Zaher Asmaa Ahmed , Al-Ghani Ahmed Mohammed
Published: March 2018

Background:

Cinnarizine, an antihistaminic drug, is commonly formulated in combination with domperidone and with paracetamol for treatment and prevention of motion sickness and migraine.

Objective:

The aim of this work was to develop new, simple, precise and selective chromatographic methods (RP-HPLC and TLC-densitometric methods) for the determination of these drugs. These methods can be used as analytical tools in the routine examination in quality control laboratories.

Methods:

The first method was RP-HPLC method, the separation was carried out on an Inertsil® ODS- 3V C18 column (250 mm × 4.6 mm, 5 µm) using a mobile phase composed of methanol: acetonitrile (45: 55, v/v) at a flow rate of 1 ml/min. The detection was carried out at 220 nm. The second method was a TLC-densitometric method where the studied components were separated using a developing system composed of toluene: ethyl acetate: methanol: triethylamine (5: 4.3: 0.7: 0.5, v/v/v/v) on TLC silica gel 60 F254 plates, followed by densitometric scanning at 270 nm.

Results:

In RP-HPLC method, the peaks were sharp and well separated, the retention times were 5.25, 3.48 and 2.78 min, for cinnarizine, domperidone and paracetamol, respectively. Linearity was obtained over the concentration ranges 1-22, 0.75-16.5 and 25-550 µg/ml, for cinnarizine, domperidone and paracetamol, respectively. In TLC-densitometric method, good separation of spots and linear relationships were achieved over the concentration ranges of 0.2-2, 0.15-1.5 and 5-50 µg/spot, for cinnarizine, domperidone and paracetamol, respectively. Method validation was conducted according to ICH guidelines in terms of linearity, accuracy, selectivity, precision and robustness.

Conclusion:

The developed methods were applied for the determination of the cited drugs in tablets containing binary drug mixtures. The methods are simple and precise and can be used for routine analysis of the labelled drugs in combined dosage forms in quality control laboratories.

Authors: Rai Aparna
Published: March 2018

Salt stress leads to an alteration in protein profile and induction of stress-specific proteins. The SDS – PAGE analysis of total soluble proteins of Anabaena sp. BHUAR002 (Accession no. bankit1353506 HM235817) exposed to 500 mM NaCl for 24 h revealed inhibition of host proteins, induction of selected proteins and appearance of some new proteins. In view of the appreciable alteration in total soluble protein profile after 500 mM salt treatment for 24 h, this dose was selected for further physiological, biochemical and proteomic analysis of the response of Anabaena sp. BHUAR002 to salinity and to examine the relationship between these responses. Further, 2DE of the total soluble protein of Anabaena sp. BHUAR002 showed 73 spots present only in control, 43 spots present only in stress and 15 differentially expressed spots present in both control and stress but show different levels of expression. This may be due to disturbance of cellular homeostasis by salt stress. Out of fifteen, Six spots were identified after MALDI-TOF MS analysis were identified as Manganese and iron Superoxide dismutase  [Anabaenavariabilis ATCC 29413], Cytidine deaminase [Porphyromonas venonis 60-3], Phycobilisome Protein [Nodularia Spumigena CCY9414], DNA replication and repair protein recF [Yersinia aldovae ATCC35236], IS1112 transposase [Xanthomonas oryzae pv.oryzae PXO99A] and TP901 family phage tail tape measure protein [Xanthobacter autotrophicus Py2].

Taxonomical and Pharmacological Status of Typha: A Review
Authors: Pandey Amit , R.K. Verma
Published: March 2018

Cattail or Typha is a genus of plants. It is found in wetland habitats. They are usually found in the Northern Hemisphere, but sometimes found in wetlands elsewhere. These plants recognized in British English as reedmace or bullrush and in American English as punks or cattail. In North America 3 species are well known, T. latifolia (broadleaf cattail), T. angustifolia (narrow leaf cattail), and southern cattail (T. dominensis). Broadleaf and southern cattails are considered native to North America. All three species are early colonizers of wetlands and compete with native wetland herbs because of their seeds dispersed by wind and rapid growth of their underground stems (rhizomes). Cattails were once used to make paper. Cattail paper is very heavy and coarse, and is rarely used today. Toxic chemical such as arsenic from drinking water has been removed by cattail because it serve as water filter. The current review discuss with the origin, distribution, chemical composition, taxonomic status and pharmacological studies.

In vitro conservation of rare, medicinally important species Dendrobum nobile Lindl. (Orchidaceae)
Authors: Kaur Saranjeet
Published: March 2018

A comparative study was made to access the regeneration response of the stem-node discs of Dendrobium nobile procured from in vivo (greenhouse) grown plants and in vitro grown cultures. The response of stem-node discs, procured both from in vivo and in vitro source, was successfully tested in M (Mitra et al., 1976) medium alone and in combinations with cytokinins [N6-benzyladenine (6-BA - 0.5, 1.0 mg l-1), furfurylaminopurine (Kn - 0.5, 1.0 mg l-1) and auxin [α-naphthalene acetic acid (NAA - 0.5, 1.0 mg l-1)]. The explants regenerated via shoot bud initiation in the cultures. Juvenility of the tissues and chemical stimulus were the major factors in initiating the response in the explants. The initiation of regeneration response in in vitro derived explants was not obligatory to a treatment with growth regulators as compared to those derived from in vivo ones. Cytokinins at 1.0 mg l-1 favoured optimum regeneration percentage in the explants and invoked additional supernumerary loci in the regenerants. The regenerants from in vitro derived explants developed plantlets early in cytokinins enriched combinations.

La política económica del fascismo italiano desde 1922 hasta 1943: breves consideraciones para su comprensión
Authors: De Corso Giusseppe
Published: March 2018

El objeto del artículo es examinar algunos aspectos relevantes de las políticas económicas fascistas en Italia durante el periodo 1922-1943. Para tal propósito se analizan las medidas tomadas entre 1922 y 1928 que precedieron a la Gran Crisis del 29, que tuvieron una orientación liberal. A partir de 1929 se comienza a desplegar un conjunto de medidas cuya intención era fascistizar la economía italiana, profundizando la arquitectura institucional corporativista y un conjunto de nuevos entes del Estado orientados al establecimiento de una economía autárquica. Por otra parte, se efectúa un breve análisis de la economía de guerra enfatizando las razones por las cuales la movilización fue limitada.
De la moneda metálica al billete de banco en Medellín y Bogotá (1871-1885): complementariedad y sustitución de medios de pago en un régimen de banca libre
Authors: Acuña Mantilla Kelly Vanessa , Álvarez Andrés
Published: March 2018

El estudio de la circulación monetaria durante la llamada era de “banca libre” en Colombia (1865-1885) muestra patrones diferentes según las regiones. Este trabajo estudia la complementariedad y sustitución entre la moneda metálica acuñada legalmente y los billetes de bancos privados. Se pone en evidencia la existencia de mecanismos de sustitución entre monedas de oro y billetes bancarios para el caso de Antioquia, mientras que en el caso de Bogotá no se puede afirmar que la evidencia sea concluyente. El patrón de comportamiento de la acuñación de monedas de plata, por el contrario, muestra complementariedad con el billete de banco en ambas regiones. Este trabajo concluye que en Colombia se presentó una forma de Ley de Gresham particular. Se muestra evidencia que permitiría concluir que las diferenciasregionales en el funcionamiento de este mecanismo se deben a la especialización de la región de Medellín (estado de Antioquia) como mayor productor y exportador de oro, de donde se puede inferir un mayor costo de oportunidad de la circulación de este metal y una tendencia a adoptar más fácilmente formas de moneda fiduciaria. Esto no es completamente cierto para Bogotá, cuya economía se especializa en agricultura, servicios comerciales y artesanado.
Los sectores agroindustriales de Argentina y Brasil, 1990-2010, y su evolución comparada
Authors: Muro de Nadal Mercedes , Merlo Susana
Published: March 2018

Las economías de Argentina y Brasil marcaron una fuerte impronta productiva y exportadora agroindustrial en las dos últimas décadas. Ambos fueron socios iniciales y promotores de la integración regional en el Mercosur, pero presentaron a lo largo del período una evolución dispar. Los principales factores que marcaron esas diferencias debemos buscarlos en el comportamiento de los mercados internacionales, las innovaciones tecnológicas, el clima, los capitales invertidos y, en especial, la incidencia de las políticas internas de cada país. Una desproporción en el tamaño de sus mercados internos, crisis internacionales, crisis dentro delos países, devaluaciones, relaciones con otros bloques y políticas de diferente signo, fueron algunos de los desafíos por los que transitaron ambos.El objetivo de este trabajo es analizar entonces la evolución del sector de la producción agroindustrial en ambos países por medio del análisis comparativo y plantear el debate académico necesario para identificar las causas de las evoluciones dispares; así mismo, sugerir cuáles son las herramientas más útiles para el desarrollo a largo plazo de Argentina o de otros países enfrentados a disyuntivas similares.

Diseño anónimo: pequeños grandes objetos
Authors: Capella Juli
Published: March 2018

Todo diseño tiene un autor, pero a menudo lo desconocemos. Los objetos jamás han nacido por generación espontánea, todo lo que no es naturaleza ha estado ideado por alguien. Por mucho que una silla sea de madera, nunca ha crecido de forma natural de un árbol. Por lo tanto el calificativo de anónimo, aplicado al diseño de objetos, no supone la ausencia de creador, sino simplemente el desconocimiento de su identidad. Nunca en la historia de la humanidad nada se ha creado solo.

INFLUENCE OF E- JOURNALS IN ACADEMIA AND SCHOLARLY COMMUNICATIONS
Authors: Arulpragasam P.
Published: March 2018

The article describes to highlight the important of e-journals for the access in the academic libraries. As academia progresses towards the 21st century, increases in student numbers, distance learning, changes in copyright licensing and lack of funding means that academic institutions have to look more closely at the use of electronic resources in order to meet these challenges. The “wired campus” and “virtual university” mean more users looking for electronic resources and increased pressure on libraries to provide these services. Electronic journals have become an increasingly important part of academic library collections; Electronic journal usage has created a new set of issues such as archiving, copyright, cataloguing, site licensing, remote access, hardware requirements and journal design. Today availability of e-resources in a university library is very common. This paper deals with different aspects of electronic journals and their impact on users, authors, indexing services, scholarly communication, accessibility and libraries. The academics are still in the process of adopting this medium. There is variation in the use of electronic journals from discipline to discipline. Researchers have positive attitude towards electronic journals. Budget allocation for journals has been shifting from print to electronic form, which has necessitated a change in collection development policies of libraries. The article describes all such aspects of electronic journals.

Published: March 2018

BACKGROUND

Mobile health (mHealth) apps provide an opportunity for easy, just-in-time access to health promotion and self-management support. However, poor user engagement with these apps remains a significant unresolved challenge.

OBJECTIVE

This study aimed to assess the effect of sending versus not sending a push notification containing a contextually tailored health message on proximal engagement, measured here as self-monitoring via the app. Secondary aims were to examine whether this effect varies by the number of weeks enrolled in the program or by weekday versus weekend. An exploratory aim was to describe how the effect on proximal engagement differs between weekday versus weekend by the time of day.

METHODS

The study analyzes the causal effects of push notifications on proximal engagement in 1255 users of a commercial workplace well-being intervention app over 89 days. The app employs a microrandomized trial (MRT) design to send push notifications. At 1 of 6 times per day (8:30 am, 12:30 pm, 5:30 pm, 6:30 pm, 7:30 pm, and 8:30 pm; selected randomly), available users were randomized with equal probability to be sent or not sent a push notification containing a tailored health message. The primary outcome of interest was whether the user self-monitored behaviors and feelings at some time during the next 24 hours via the app. A generalization of log-linear regression analysis, adapted for use with data arising from an MRT, was used to examine the effect of sending a push notification versus not sending a push notification on the probability of engagement over the next 24 hours.

RESULTS

Users were estimated to be 3.9% more likely to engage with the app in the next 24 hours when a tailored health message was sent versus when it was not sent (risk ratio 1.039; 95% CI 1.01 to 1.08; P<.05). The effect of sending the message attenuated over the course of the study, but this effect was not statistically significant (P=.84). The effect of sending the message was greater on weekends than on weekdays, but the difference between these effects was not statistically significant (P=.18). When sent a tailored health message on weekends, the users were 8.7% more likely to engage with the app (95% CI 1.01 to 1.17), whereas on weekdays, the users were 2.5% more likely to engage with the app (95% CI 0.98 to 1.07). The effect of sending a tailored health message was greatest at 12:30 pm on weekends, when the users were 11.8% more likely to engage (90% CI 1.02 to 1.13).

CONCLUSIONS

Sending a push notification containing a tailored health message was associated with greater engagement in an mHealth app. Results suggested that users are more likely to engage with the app within 24 hours when push notifications are sent at mid-day on weekends.
Variability in Electronic Health Record Use for Medication Management in Primary Care (Preprint)
Authors: Montague Enid
Published: March 2018

UNSTRUCTURED

Background: Traditional medication management complexity now combined with EHR systems, which are still novel in primary care settings, propose new challenges in trying to improve physician workflow.
Objective: The purpose of this study was to understand how workflow variability in medication management using an electronic health record (EHR) system is related to patient and physician factors.
Methods: Two different patient cases (chronic vs. acute condition) were presented to participants in a controlled environment. A task action coding scheme was used to analyze the videotaped data from the physician’s EHR usage. A usability survey was administered after the task.
Results: High variability in the medication review process and EHR perceptions were revealed. Patient conditions and physicians’ EHR perceptions were related to the found variability in the workflow.
Conclusions: Interventions designed to improve EHR medication management in primary care should consider alignment with physician’s varied workflow linked with their perceptions and differing patient condition.
Pareto Set as a Model for Dispatching Resources in Emergency Centres (Preprint)
Authors: Guedes Ricardo , Furtado Vasco , Pequeno Tarcísio , Rodrigues Joel
Published: March 2018

UNSTRUCTURED

The article investigates policies for helping emergency-centre authorities for dispatching resources aimed at reducing goals such as response time, the number of unattended calls, the attending of priority calls, and the cost of displacement of vehicles. Pareto Set is shown to be the appropriated way to support the representation of policies of dispatch since it naturally fits the challenges of multi-objective optimization. By means of the concept of Pareto dominance a set with objectives may be ordered in a way that guides the dispatch of resources. Instead of manually trying to identify the best dispatching strategy, a multi-objective evolutionary algorithm coupled with an Emergency Call Simulator uncovers automatically the best approximation of the optimal Pareto Set that would be the responsible for indicating the importance of each objective and consequently the order of attendance of the calls. The scenario of validation is a big metropolis in Brazil using one-year of real data from 911 calls. Comparisons with traditional policies proposed in the literature are done as well as other innovative policies inspired from different domains as computer science and operational research. The results show that strategy of ranking the calls from a Pareto Set discovered by the evolutionary method is a good option because it has the second best (lowest) waiting time, serves almost 100% of priority calls, is the second most economical, and is the second in attendance of calls. That is to say, it is a strategy in which the four dimensions are considered without major impairment to any of them.

Published: March 2018

Background: The risk of death caused by non-communicable diseases is related to metabolic syndrome. Metabolic syndrome not only occurs in adults, but also occurs in adolescents. The problem of metabolic syndrome in adolescents shows the importance of early detection and management. Early detection of metabolic syndrome in adolescents can be done through non-invasive approaches such as anthropometric measurements. However, the definition of metabolic syndrome has so far not reached an agreement.Objective: This study aims 1) To know the intersection points of adolescent metabolic syndrome 2) To know the best anthropometry parameters for detecting metabolic syndrome in adolescents.Method: This study used cross sectional design, using Riskesdas 2013 survey data. The sample size of this study was 3273 adolescents aged 15-24 years. The analysis using receiver operating characteristic curve (ROC) indicated the accuracy of the score to diagnose metabolic syndrome, supported by area under the curve (AUC) results. The best parameters were seen from the largest AUC values, taking into account the sensitivity and specificity values.Results: The metabolic syndrome scores in general for Indonesian adolescents=2.21 (sensitivity=83%, specificity=84%). Specific cutoff point for women=2.02 (sensitivity=84%, specificity=85%), and for males=2.40 (sensitivity=86%, specificity=82%). The best anthropometric parameters for detecting metabolic syndrome in adolescents are abdominal circumference (AUC=0.77; sensitivity=71%, specificity=67%).Conclusion: Abdominal circumference has the best validity and can be used for early detection of the risk of metabolic syndrome in adolescents

As Abordagens Policiais e o Caso Miranda v. Arizona (1966): violência institucional e o papel das cortes constitucionais na garantia da assistência do defensor na fase policial
Authors: Ponte Carvalho Gabriela , Piza Duarte Evandro
Published: March 2018

O texto analisa a doutrina construída a respeito dos direitos do acusado nos Estados Unidos, a partir da decisão da Suprema Corte no caso Miranda v. Arizona (1966). Descreve-se o modo como o direito de não produzir prova contra si (nemo tenetur se detegere) se manifesta na fase de policiamento, identificação de suspeitos e investigação policial. Pretende-se, com isso, demonstrar as diferenças entre o direito estadunidense e o direito brasileiro, realçando, neste caso, o caráter essencialmente formal das interpretações que visam a garantir direitos aos suspeitos. Desse modo, intenta-se demonstrar a responsabilidade pela violência institucional presente em decisões do Supremo Tribunal Federal, que, ao contrário da Suprema Corte dos Estados Unidos, não se defronta com as dimensões práticas e constitucionais da custódia de suspeitos e das confissões feitas na fase policial.
