The Bayesian Additive Main Effects and Multiplicative Interaction can deal with unbalanced data.

The Additive Main Effects and Multiplicative Interaction elipses can capture the uncertain about unbalanced data sets.

The cross‐validation results showed the ability of Bayesian Additive Main Effects and Multiplicative Interaction in genotypes × environments interaction predictions.

The identification of genotypes presenting wide adaptability and stability is pivotal in breeding programs. To identify such genotypes, it is necessary to use sophisticated analytical tools to establish the genotypes × environments interaction (GEI) pattern across multi‐environment trials and select for genotypic stability and adaptability. The aim of the present study was to estimate GEI using Bayesian analysis of Additive Main Effects and Multiplicative Interaction (AMMI) models for both balanced and unbalanced data sets and estimate the predictive ability of model. Two studies were assessed to showcase this approach; in the first, 10 commercial maize (Zea mays) single‐cross hybrids and 45 double‐cross hybrids were evaluated at 15 different locations. In the second study, 28 hybrids were evaluated in 35 different environments distributed over two different harvest seasons (first and second harvests) with unbalanced data sets within and between harvests. The Bayesian analysis of the AMMI models was robust in dealing with the unbalanced data. This approach is promising for the identification of interaction patterns and the estimation of GEI. The genotypes and environments could be grouped according to their interaction patterns even using the unbalanced data sets, showing that Bayesian analysis of AMMI models could be applied effectively for multi‐environment trials. The prediction for missing hybrids was satisfactory in a simulated unbalanced design and captured the GEI and patterns in the data. This allowed the direct comparison of genotypes from the first and second harvests and the estimation of selection gain.
No‐Till Green Manure Termination Influences Soil Organic Carbon Distribution and Dynamics
Authors: Marshall Carolyn B , Lynch Derek H
Published: July 2018

Core Ideas

Soil organic C pools increased under no‐till green manure termination, and this increase persisted over 3 yr following the green manure termination method.

Total organic C and particulate organic matter C showed a stronger response to the green manure termination method than permanganate oxidizable C.

Tillage effects in labile soil organic C pools may be harder to detect in organic systems with high levels of C inputs.

There is continued interest in adopting no‐till practices in organic agriculture. One way to decrease tillage is to implement no‐till termination of green manures. Studies on this novel approach have focused primarily on cash crop performance and weed control. The objective of this study was to examine soil organic C distribution and dynamics as influenced by different methods of green manure termination of a spring‐planted green manure. In this green manure–wheat (Triticum aestivum L.)–fall rye (Secale cereal L.)–soybean [Glycine max (L.) Merr.] rotation three green manure termination methods were compared (no‐till crop roller, spring tillage, and fall tillage). A mixture of hairy vetch (Vicia villosa Roth)–oat (Avena sativa L.) was seeded in late May in two trials, the first commencing in 2013 and the second in 2014. Soil organic C was monitored for 3 yr after green manure termination. In Trial 2, total organic C was greater under no‐till green manure termination compared to fall and spring‐till termination (by 2.4 ± 1.2 Mg C ha−1 and 2.3 ± 1.3 Mg C ha−1, respectively) and the effect remained significant in all 3 yr. In Trial 1, particulate organic matter C was stratified in no‐till and concentrated at the soil surface (0–5cm) and higher overall in no‐till in Trial 2. Overall soil organic C was higher under no‐till green manure termination and the more labile pool of POXc appeared less responsive to termination treatments.
“Ruim com ele, pior sem ele”: servidão (in)voluntária que reforça o trabalho escravo contemporâneo, apontamentos à luz da Psicodinâmica do Trabalho
Authors: Vieira Fernando De Oliveira , Marinho Maiara Oliveira , Ghizoni Liliam Deisy
Published: July 2018

Objetiva-se abordar o tema da servidão voluntária entrelaçado às definições de trabalho escravo contemporâneo, tecendo apontamentos com o olhar da Psicodinâmica do Trabalho.Questiona-se: a organização do trabalho contemporâneo não estaria orientada por um discurso de servidão voluntária? A noção de servidão voluntária escrita por La Boétie em meados do século XVI, constitui o centro do debate por trazer em seu bojo a presença constante e atemporal da opressão. Trabalho escravo é um crime contra a dignidade humana, ele é visualizado quando um sujeito submete outro a: trabalhos forçados, jornada exaustiva, condições degradantes e restrição de liberdade. Para a Psicodinâmica do Trabalho, há um claro esmagamento do sujeito que deseja trabalhar mas vive a obrigação de servir. Conclui-se que a servidão voluntária se encontra viva na atualidade, diante das situações de escravidão contemporânea vivenciadas, tanto no meio rural, quanto urbano. Destarte, propõe-se uma agenda de pesquisas sobre a temática para o campo da Administração, que envolvem: o ideal de ego na sociedade de consumo; a escravidão contemporânea e a analogia à escravidão, e o trabalho, a subjetividade e a emancipação.

A Simplified Simulation Model to Estimate the Storage Length of the Right-Turn Lane in Left-Hand Traffic at Signalised Intersections for Different Signal Phases and Cycle Timings
Authors: Ishak-Thomas Noura , Richardson Steven , Shukla Sanjay Kumar
Published: July 2018

Introduction:

A large number of the current guidelines and models are used to estimate the right-turn lane (RTL) length in left-hand traffic at signalised intersections under split phase, in which the movement of traffic in the right-turn lane and through lane happen concurrently. There is a need to examine other phase types and timings as a part of the RTL design. This is particularly significant in the case of established intersections that cannot be modified due to physical constraints.

Methods:

A MATLAB based simulation programme was developed to provide an estimate of the right-turn lane storage length for different traffic volumes in order to avoid the problems associated with blockage and overflow of the right turn vehicles in 95% of the traffic signal cycles. The model enhances flexibility when dealing with the complexity of the design of the storage length taking into account different signal phases and timings to overcome the aforementioned problems. The simulation model also takes into consideration the left-over queue from the previous cycle which was ignored by most of the previous studies.

Results and Conclusion:

The model input includes as a configuration matrix containing the sequence of operational states of the intersection. This ensures the flexibility and the simplicity of manipulating the data to reflect all phase types and timings. The model results have been compared against a recently developed analytical model in which similar signal phases and timings were investigated. The outcomes agree to the results that are obtained from the analytical model in most of the signal phases. The developed simulation model is flexible enough to be used further to simulate the situation when there is a large difference between the approaching and opposing traffic volumes and optimise the green time in case of split phase. In this study, the simplified simulation model for estimating the RTL storage length has been developed for the left-hand traffic countries; however, the study is equally applicable to the left-turn lane (LTL) in right-hand traffic countries.
Abdominal Obesity Index as an Alternative Central Obesity Measurement During a Physical Examination
Authors: Amankwah Nigel , Brunetti Ryan , Kotha Vikas , Mercier Cassidy , Li Lin , Ding Jing , Han Zhiyong
Published: July 2018

Background:

Although BMI (body mass index) has been widely used to determine whether an individual is underweight, normal weight, overweight, or obese, its clinical usefulness for obesity study has been called into question because it does not specifically describe body fat content and distribution and has limited relevance to central obesity, which is most relevant to health risks. Although imaging techniques are used to determine central obesity, they are expensive and are thus not used in a routine physical examination of patients in medical offices.

Objective:

Developing an easy-to-use ABOI (Abdominal Obesity index) to measure central obesity during a physical examination.

Methods:

ABOI is an index utilized to assess central obesity of patients. To determine ABOI, two measurements are taken from the torso; the outer circumference of the thoracic segment, C1, at the xiphoid process and the outer circumference of the abdominal segment, C2, at the point of largest girth. The volume of the abdominal segment is divided by the volume of the thoracic segment to derive ABOI (V2/V1 = [C2]2/[C1]2). Thus, ABOI is the square of the ratio of the circumference of the abdominal segment to the circumference of the thoracic segment of the torso. Moreover, the ABOI does not concern total body weight, body height, or body shape (e.g. “apple-shaped” or “pear-shaped” body types). Instead, ABOI specifically highlights central obesity. We randomly recruited 282 subjects, ages 20-90 years, at a community health service center in Beijing, China, and determined their ABOI and BMI values.

Results:

The mean (standard deviation) BMI for the female and male subjects is, respectively, 24.24 kg/m2 (3.35) and 24.86 kg/m2 (3.25). For ABOI, mean (standard deviation) is 1.17 (0.16) and 1.01 (0.13) for females and males, respectively. There is no strict relationship between ABOI and BMI in the context of obesity as defined by high BMI values, and ABOI appears to be a more specific measure of central obesity than BMI.

Conclusion:

ABOI is a useful and distinct independent measurement of central obesity, and ABOI (possibly in combination with the waist-to-height ratio) appears to be a more specific way to assess central obesity during a physical examination.

Published: July 2018

The air pollution problem remains, although significant improvements have been seen in urban air quality over the last years. This study aims to show that the spatial statistic techniques can well be used to examine and explain the air pollution levels in urban areas. The data for SO2 and NO2 concentrations are measures using passive diffusion tubes at the 67 monitoring sites in the district of Çiğli (Izmir). The tubes were exposed for a 2-week period in August 2015. For the determination of the level of clustering for high values and low values of pollutants, Getis-Ord G* local statistics are calculated. There are five points with high values of SO2 surrounded by low values, three points of NO2, where the results are statistically significant at the 0.10 level. The presence of the industrial zone, the form of fossil fuels used in heating, and topography are strong determinants urban air pollution.

Published: July 2018

Los ecosistemas de la región Mixteca han estado sometidos a la deforestación, el sobrepastoreo y prácticas agrícolas inadecuadas, y como resultado los suelos se han degradado. Para atenuar este problema, desde tiempos ancestrales los pueblos mixtecos han establecido el sistema lama-bordo como estrategia para retener suelo, manejar los escurrimientos superficiales y retener humedad. Para tener evidencia de la efectividad del sistema lama-bordo se analizó la variabilidad espacial de las propiedades físicas (textura, densidad aparente, capacidad de campo y punto de marchitez permanente) y químicas (pH, materia orgánica, nitrógeno, fósforo, potasio y carbono orgánico) de los suelos retenidos en un sistema en el municipio de Teotongo, Oaxaca; este sistema tiene 8.47 ha distribuidas en 11 parcelas donde se tomaron muestra de suelos a 0.30 m de profundidad. Las propiedades físicas y química de los suelos muestran alta variabilidad espacial relacionada con la posición del muestreo y la antigüedad de la terraza. El análisis estadístico mostró diferencias estadísticamente significativas (a<0.05) en los contenidos de materia orgánica, nitrógeno, potasio, carbono orgánico, arcilla, capacidad de retención de agua y conductividad hidráulica entre las márgenes derecha, izquierda y central y la antigüedad en la construcción de las parcelas.
Isomorfismo de los servicios de telecomunicaciones: un análisis cuantitativo
Authors: Camargo Mayorga David Andrés , Cardona García Octavio , Roncancio García Ángel David
Published: July 2018

El isomorfismo mimético según DiMaggio & Powell (1983) ocurre en campos organizacionales en donde el esfuerzo racional de cada empresa por contrarrestar la incertidumbre, conduce a una homogeneidad entre organizaciones; lo cual se supondría que ocurre en el sector telecomunicaciones a nivel mundial. Para comprobar esta hipótesis, este artículo presenta un modelo de panel de datos desbalanceado que tiene como propósito determinar las diferencias existentes en la prestación de servicios de telecomunicaciones para 69 países. El periodo considerado para el estudio correspondió al quinquenio 2010 – 2015. Los hallazgos principales sugieren la existencia de diferencias en la prestación de los servicios entre países, que no solo se explican por la tecnología, sino que involucran la incidencia de instituciones informales. Se concluye que no existe aún isomorfismo a nivel de los países analizados.

RESUMO O texto centra-se na an�lise dos fluxos migrat�rios femininos do Brasil para Portugal no �mbito da ind�stria do sexo, sobre os quais recai uma discursividade antitr�fico hegem�nica produzida por protocolos internacionais, entidades governamentais, for�as de seguran�a e ONGs, que tende a estabelecer uma estrita associa��o entre trabalho sexual e tr�fico de pessoas. Procuramos examinar os processos, recursos e estrat�gias subjacentes � constru��o das mobilidades em causa, num quadro de fortifica��o do continente europeu e de crescente repress�o das migra��es internacionais. Por outro lado, tentamos delinear uma an�lise cr�tica dos discursos institucionais exacerbados sobre o fen�meno do tr�fico de pessoas e as respetivas conce��es vitimizantes das mulheres migrantes que exercem o trabalho sexual, n�o lhes reconhecendo possibilidades de autodetermina��o e de ag�ncia.
"We, The Black People": um percurso etnogr�fico sobre Direitos, Viol�ncias e Demandas p�blicas na Ba�a de S�o Francisco, Calif�rnia (EUA)

Published: July 2018

Neste artigo irei refletir sobre o per�odo de 12 meses que passei na Calif�rnia (EUA) para a realiza��o do meu doutorado sandu�che. Descreverei alguns dos itiner�rios que percorri na tentativa de apreender certos aspectos da vida social dos mortos na regi�o da Ba�a de S�o Francisco, particularmente daqueles v�timas de agentes estatais. Ao procurar mapear caminhos das v�timas de �police brutality� (brutalidade policial), fosse no sistema de justi�a criminal ou nos circuitos de ativistas e pol�ticos, encontrei-me com a centralidade hist�rico-social da �quest�o racial� naquele contexto. A morte do jovem Mario Woods, v�tima letal do excesso de viol�ncia policial e as demandas por justi�a relativas � sua morte, demonstram como as demandas p�blicas por �black lives matter� (vidas pretas importam) encontram e resistem �s viol�ncias que atingem essas vidas.

Entre pessoa, corpo e coisa: a vida social de cad�veres em laborat�rios de anatomia
Authors: Neves Marcos Freire de Andrade
Published: July 2018

A presença de cadáveres em laboratórios universitários de anatomia é observada, pelo menos, desde o século XVI. Alvo de polêmicas no decorrer de seus primeiros momentos, a prática, atualmente, é garantida pela Constituição Federal Brasileira, que define não apenas as finalidades para as quais tais cadáveres podem ser utilizados, como também quais podem ser estes cadáveres. A partir de um laboratório de anatomia de uma universidade na cidade de Porto Alegre, busca-se refletir acerca do estatuto dos corpos que lá se encontram, questionando, fundamentalmente, o processo através do qual estes foram cedidos ao laboratório. Regido por acordos entre as partes cedente e receptora, o processo formula uma dinâmica legal na qual o corpo humano torna-se algo passível de ingressar em um sistema de troca. Uma dinâmica em que a institucionalização do cadáver pelo Departamento Médico Legal (DML) e sua cessão ao laboratório acabam por ressignificar o corpo ao transpô-lo do estatuto de pessoa para o de coisa.

“É extraordinário que já tenham se passado vinte e quatro anos desde que ele foi publicado”1, relembra Tim Ingold ao autorizar a tradução para o português deste editorial da Revista Man2, que não só apontava um cenário futuro para a Antropologia no início dos anos noventa, como delineava os contornos de um empreendimento no qual o próprio autor foi um agente ativo. Desde o trabalho de campo entre os Skolt Sami, na Finlândia, ainda nos anos setenta, este antropólogo britânico vem construindo um percurso original na disciplina. Ao rever sua própria trajetória intelectual, Ingold (2011, p. 4) retoma os fios de uma malha de termos-chave que estão emaranhados na tessitura das distintas fases do seu trabalho intelectual. Partindo do significado de produção, passando pelo sentido de história, chegando à noção de habitar para explorar atualmente como a vida se desenvolve ao longo de linhas, o seu work in progress consolidou uma contribuição inestimável para repensar a relação entre natureza e sociedade/cultura, ao afirmar a indissociabilidade entre o modo de habitar o mundo, o mover-se nele e a forma de vir a conhecê-lo.

Numa espécie de preâmbulo do Ensaio sobre a Dádiva, Marcel Mauss (1999) sublinhou que, em algumas línguas germânicas, havia um parentesco semântico entre as palavras presente e veneno. Pouco a pouco, Mauss delineava que o parentesco linguístico era tão somente um indicativo de um fenômeno social mais amplo: dívida e graça, privilégio e obrigações caminham proximamente. Quase cem anos depois desse escrito, quando as agências esportivas internacionais escolheram o Brasil como sede dos principais megaeventos internacionais – a Copa do Mundo (2014) e os Jogos Olímpicos do Rio (2016) – a população não hesitou em celebrar a escolha. Muitos viram ali, uma chance quase única, singular de transformação do país e da sociedade brasileira. Mas o enredo é conhecido, e a reconversão da benesse em maldição não tardou. As altas somas de dinheiro público dispendidas, as demandas arquitetônicas das agências esportivas internacionais – o vulgarizado “padrão FIFA” –, e o estrito cronograma foram seguidamente questionados pela sociedade civil nacional, culminando com os levantes de junho em 2013.

Demographic Factors as a Catalyst for the Retention of Academic Staff: A Case Study of Three Universities in Sub - Saharan Africa
Authors: Gurmessa Z. B. , Ferreira I. W. , Wissink H. F.
Published: July 2018

The aim of the study was to determine the effect that demographic factors such as age, gender, marital status and education, as well as factors such as years of experience, income, academic rank, country of origin and area of specialisation have on academic staff working in the higher education sector in Sub Saharan Africa . A survey approach was adopted as the main data collection tool and data was collected from three public Universities - University of KwaZulu- Natal (UKZN), Addis Ababa University (AAU) and Haramaya University (HU). The first university is located in South Africa and the last two universities are situated in Ethiopia. The survey was employed as a research design. A self- administered survey questionnaire consisting of both demographic variables (age, tenure, educational level, academic rank, employment status, marital status, average income level, and fields of specialisation) and six item turnover intentions or intentions to stay variables (measured a five -point Likert Scale in which 1= Strongly Disagree; 2= Disagree; 3= Neither Agree Nor Disagree; 4= Agree and 5= Strongly Disagree) were completed by 596 respondents selected by means of the stratified sampling method. The data was analysed using the Statistical Package of the Social Sciences(SPSS) software packages version 24. Both descriptive (frequencies, mean and standard deviation) and inferential (one-way-ANOVA) statistics were applied to examine the effect of the various demographic and other factors on the academic staff membersâ€™ intentions to depart from or remain at the three universities. The study revealed that the effect of these factors on the academic staffâ€™s intention to depart or remain varied across the three universities . The study concluded that age, educational level, rank, employment status, marital status and area of specialisation were significant at HU but not at UKZN, where none of these factors were found to be significant predictors of a staff memberâ€™s intention to depart from the university. The findings of this study will enable higher education leaders and human resource practitioners in general, but Ethiopian institutions in particular, to design an acceptable human resource strategy and policy, tailored to address diversity and overcome the temptations of â€œone- size - fits - allâ€ retention strategies.
Growth Constraints of Formal and Informal Micro and Small -Scale Enterprises and Their Impact on Policy Formulation in Zimbabwe
Authors: Mukorera Sophia
Published: July 2018

The new view on MSEs in the informal sector perceives them as being permanent, stable activities comprised of dynamic businesses that affect most economic activities. As such, they need to be considered in economic policies to ensure that they can grow and contribute to the national economy. In Zimbabwe, policies for entrepreneurial development are mainly informed by formal - sector enterprises. This study analysed the similarities and differences in the growth constraints of MSEs operating in the formal and informal sectors in Harare, Zimbabwe . Using descriptive statistics and principal component analysis, the study analysed 21 internal and external growth constraints. The findings were that formal - sector MSEs perceive internal factors as constraining them the most, while informal MSEs perceive external factors as constraining them the most. The study concludes that a common policy approach cannot work in addressing the needs of the two sectors. Sector- specific policies need to be formulated in order for the enterprises in both sectors to fully contribute to the national economy.

During puerperium phase in cows, uterus goes through involution process,
while ovaries restore supressed cyclicity as a result of gestation. After
10-20 days postpartum (PP) luteinizing hormone (LH) levels begin to raise and
renewal of cyclicity after parturition is probably most important factor for
cows to successfuly conceive again. Almost 95% of dairy cows should restore
ovarian cyclicity up to 50 days postpartum. LH surge is important for
ovulation and luteinisation of granulosa and theca cells into luteal cells
and proliferation of blood vessels. Up to 79% of newly formed corpora lutea
have central vacuola, filled with fluid. The study involved the total of 54
Holstein-Friesian cows, during first 40 days of lactation. Examinations of
the ovaries, were performed in the period from 10 to 40 days postpartum.
Ovaries and corpora lutea were first palpated and then examined using
portable diagnostic ultrasound linear scanner MyLab?30 VETGold portable
ultrasound linear scanner with endorectal linear probe LV 513, 5-7.5 MHz
(both Esaote SpA, Italy). The same equipment was used to monitor BCS, while
lamenes was assessed using Zinpro Locomotion Score for dairy cows. The
highest number of corpora lutea was observed after 20 and 30 days postpartum
in experimental and control groups. More corpora lutea were observed in
multiparous cows. Higher numbers of corpora lutea with similar average size
were observed in right ovaries of cows in both groups, while corpora lutea
were bigger in multiparous cows. Numbers and sizes of corpora lutea, may give
an insight in quality of restoration of ovarian cyclicity and a solid base

The experiment was carried out to evaluate the possibility of ensiling common
vetch - oat mixtures sown at five different seeding rates. Two effects were
studied: seeding rate of common vetch and oat in the mixtures and
application of bacterial inoculant. The pH, DM (Dry Matter) content, ammonia
nitrogen, soluble nitrogen, lactic, acetic and butyric acids were determined
on silages. DLG method was utilized for classification the silage quality.
Common vetch and oat were grown in binary mixtures at the experimental field
of the Institute for forage crops, Krusevac - Serbia, and were tested at
five different mixture rates: pure vetch, 25% vetch + 75% oat, 50% vetch +
50% oat, 75% vetch + 25% oat and pure oat. Application of bacterial
inoculant affected higher content of ammonia nitrogen and acetic acid (P<
0.05), but lower content of soluble nitrogen (P< 0.05). Depending on the
seeding rates of common vetch and oat, 75 : 25 common vetch - oat silage had
the highest content of lactic acid and the lowest content of butyric acid.
Contents of DM, pH and ammonia nitrogen were similar in all silages ranged
from 307.2 to 318.5 g kg-1, from 4.27 to 4.54 and from 16.1 to 19.1% ?N,
respectively. According to the DLG method for silage quality evaluation,
similar quality grades were founded.
Institutionalist versus neoclassical view on income distribution and economic progress: The OECD panel evidence
Authors: Josifidis Kosta , Supic Novica
Published: July 2018

Institutionalist and neoclassical views on income distribution are
characterized by different assumptions about the inequality - savings -
economic progress relationship. By questioning the neoclassical arguments,
the paper promotes the attitude that economic progress results not from
savings as ?abstain from current consumption? but from society?s ability to
continuously develop technological arts and crafts. Empirical analysis of
panel data from OECD countries using a dynamic GMM model shows a positive
relationship between income concentration and aggregate savings, but there
is no robust evidence of a positive relationship between aggregate savings
and economic progress. Furthermore, we find robust evidence that technology
and human capital are the key determinants of economic progress, implying
that accumulation of physical and human capital is more important for
economic progress than accumulation of financial capital.

Published: July 2018

In this work, influence of annealing temperature on the electrical properties of unmodified bentonite has been investigated. It is concluded that, by the increase of annealing temperature, the values of permittivity and conductivity are decreased, but the electric resistance and the density of the bentonite are increased. It is also shown that the basic reason for this is the presence of water molecules and alkaline oxides such as Na2O, K2O in bentonite.
A Hybrid Model of Artificial Neural Network and Genetic Algorithm in Forecasting Gold Price
Authors: Khamis Azme Bin , Yee Phang Hou
Published: July 2018

The goal of this study is to compare the forecasting performance of classical artificial neural network and the hybrid model of artificial neural network and genetic algorithm. The time series data used is the monthly gold price per troy ounce in USD from year 1987 to 2016. A conventional artificial neural network trained by back propagation algorithm and the hybrid forecasting model of artificial neural network and genetic algorithms are proposed.  Genetic algorithm is used to optimize the of artificial neural network neurons. Three forecasting accuracy measures which are mean absolute error, root mean squared error and mean absolute percentage error are used to compare the accuracy of artificial neural network forecasting and hybrid of artificial neural network and genetic algorithm forecasting model. Fitness of the model is compared by using coefficient of determination. The hybrid model of artificial neural network is suggested to be used as it is outperformed the classical artificial neural network in the sense of forecasting accuracy because its coefficient of determination is higher than conventional artificial neural network by 1.14%. The hybrid model of artificial neural network and genetic algorithms has better forecasting accuracy as the mean absolute error, root mean squared error and mean absolute percentage error is lower than the artificial neural network forecasting model.

Authors: Gião Paulo Roberto , Oliveira Júnior Moacir de Miranda
Published: July 2018

A transferência de parte ou de toda uma cadeia de valores para um local com menores custos – denominada Offshoring - tem se expandindo por vários países do mundo. A princípio, as empresas terceirizavam serviços para países em desenvolvimento para reduzir custos, hoje, também o fazem para ter acesso à mão-de-obra qualificada. Neste estudo, objetiva-se identificar o potencial do Brasil como provedor de serviços para outros países. Para tanto, estabeleceu-se uma comparação entre as características do Brasil e da Índia, levando em conta os drivers (direcionamentos) que a tornaram o principal pólo de offshoring de serviços da atualidade. Constatou-se que, embora a capacidade criativa e profissional do brasileiro seja reconhecida internacionalmente, o percentual de pessoas com fluência em língua inglesa é insuficiente para expansão de call centers, back-office e outros tipos de offshoring no Brasil.Palavras-chave: Offshoring.

Published: July 2018

Muitas empresas globais proativas às mudanças constantes do mercado, para acessar os ativos complementares, satisfazer os clientes, buscar o crescimento e vantagem competitiva sustentável estão praticando a open innovation, um novo paradigma que utiliza técnicas e ferramentas para o desenvolvimento de uma rede de inovação colaborativa. Além disso, há estudos que sugerem que a empresa deve ser orientada ao mercado para a inovação ser bem sucedida. Portanto, esta pesquisa procurou contribuir com o corpo científico abordando o novo paradigma de open innovation (Chesbrough, 2003) e a estratégia difundida de orientação para o mercado no âmbito da inovação. Dessa forma, buscou-se verificar se existe correlação positiva entre open innovation, inovação e orientação para o mercado com base nos 3 pilares de Jaworki e Kohli (1993). O estudo empírico foi desenvolvido mediante uma pesquisa quantitativa com aplicação de um questionário em diferentes níveis funcionais das empresas. Para o tratamento dos dados adotou-se a técnica estatística de correlação de Spearman. Os resultados atrelados ao arcabouço teórico demonstraram que a inovação está relacionada com a orientação para o mercado, mas não há uma relação significativa deste com open innovation. Verificou-se também a existência de deficiência na geração e disseminação da inteligência, sendo estes, determinantes para a correlação entre orientação para o mercado e open innovation.
KNOWLEDGE MANAGEMENT AND COLLABORATION EFFECTS: SOUTH-SOUTH NGO COLLABORATION: A CASE STUDY ON THE BRAZILIAN INTERDISCIPLINARY AIDS ASSOCIATION

Authors: Keeney Grace
Published: July 2018

In June 2008, the Brazilian Interdisciplinary AIDS Association (ABIA) and the Indian NGO SAHARA submitted a joint pre-grant opposition to the patent application of Tenofovir Disoproxil Fumarate in India. This joint action provides a pertinent case model of the potential effects of South-South cooperation between civil society groups. In this study, the aim sought to determine the practicality of the methodology and propositions developed in Resources, Knowledge and Influence: the Organizational Effects of Interorganizational Collaboration (Hardy et al., 2003) in predicting the types of collaboration effects that would result from the degree of “involvement” and “embeddedness” of a collaboration. Data collection came from archival research, participant observation research and interviews. Research tasks included an investigation on South-South Cooperation in the area of IP rights and AIDS, compiling an SLR on knowledge management and collaboration theories, creating a chronology of the collaboration and application of aforementioned methodology. Application included (1) implementation of codification methodology based on “involvement” and “embeddedness” and (2) identification of types of effects in collaboration - strategic, knowledge creation or political. During data analysis, these effects were compared with the aims of collaboration. Results were then tested against propositions (Hardy et al., 2003) of the relationship between involvement and embeddedness and the collaborative effects. Findings support three propositions: (1) Collaborations with high levels of involvement will be positively associated with the acquisition of distinctive resources, (2) Collaborations with high levels of involvement and high levels of embeddedness will be positively associated with the creation of knowledge, (3) Collaborations that are highly embedded will be positively associated with an increase of influence.

A partir da primeira década dos anos 2000 percebe-se um aumento das discussões a respeito do tema da sustentabilidade, onde se enquadra o tema da Bioenergia, no qual o Brasil tem chamado atenção pelos avanços na indústria do etanol. Avanços na tecnologia de motores refletiram novas oportunidades para essa indústria e, de acordo com o Plano Decenal de Energia Elétrica para 2019 elaborado pelo ministério de Minas e Energia, há uma expectativa de aumento na demanda de etanol em 90% até 2019 (BRASIL, 2010). No entanto, novas tecnologias de conversão e de uso da cana de açúcar e o contexto complexo no qual se insere essa indústria adicionam incertezas nesse setor. Foi com o objetivo de discutir e colocar as incertezas na agenda dessa indústria que nesse trabalho se propôs a elaborar e discutir cenários prospectivos para a demanda por cana de açúcar. Quatro cenários com diferentes perspectivas de avanço tecnológico e de desenvolvimento de mercados foram elaborados e discutidos na conclusão do trabalho.
