An Indoor Positioning Approach Based on Fusion of Cameras and Infrared Sensors
Authors: Martín-Gorostiza Ernesto , García-Garrido Miguel A. , Pizarro Daniel , Salido-Monzú David , Torres Patricia
Published: June 2019

A method for infrared and cameras sensor fusion, applied to indoor positioning in intelligent spaces, is proposed in this work. The fused position is obtained with a maximum likelihood estimator from infrared and camera independent observations. Specific models are proposed for variance propagation from infrared and camera observations (phase shifts and image respectively) to their respective position estimates and to the final fused estimation. Model simulations are compared with real measurements in a setup designed to validate the system. The difference between theoretical prediction and real measurements is between 0.4 cm (fusion) and 2.5 cm (camera), within a 95% confidence margin. The positioning precision is in the cm level (sub-cm level can be achieved at most tested positions) in a 4 × 3 m locating cell with 5 infrared detectors on the ceiling and one single camera, at distances from target up to 5 m and 7 m respectively. Due to the low cost system design and the results observed, the system is expected to be feasible and scalable to large real spaces.

Published: June 2019

Internet of Things (IoT) technology has been attracted lots of interests over the recent years, due to its applicability across the various domains. In particular, an IoT-based robot with artificial intelligence may be utilized in various fields of surveillance. In this paper, we propose an IoT platform with an intelligent surveillance robot using machine learning in order to overcome the limitations of the existing closed-circuit television (CCTV) which is installed fixed type. The IoT platform with a surveillance robot provides the smart monitoring as a role of active CCTV. The intelligent surveillance robot, which has been built with its own IoT server, and can carry out line tracing and acquire contextual information through the sensors to detect abnormal status in an environment. In addition, photos taken by its camera can be compared with stored images of normal state. If an abnormal status is detected, the manager receives an alarm via a smart phone. For user convenience, the client is provided with an app to control the robot remotely. In the case of image context processing it is useful to apply convolutional neural network (CNN)-based machine learning (ML), which is introduced for the precise detection and recognition of images or patterns, and from which can be expected a high performance of recognition. We designed the CNN model to support contextually-aware services of the IoT platform and to perform experiments for learning accuracy of the designed CNN model using dataset of images acquired from the robot. Experimental results showed that the accuracy of learning is over 0.98, which means that we achieved enhanced learning in image context recognition. The contribution of this paper is not only to implement an IoT platform with active CCTV robot but also to construct a CNN model for image-and-context-aware learning and intelligence enhancement of the proposed IoT platform. The proposed IoT platform, with an intelligent surveillance robot using machine learning, can be used to detect abnormal status in various industrial fields such as factory, smart farms, logistics warehouses, and public places.

Authors: Sakhakarmi Sayan , Park JeeWoong
Published: June 2019

The application of tactile-based wearable devices to assist in navigation for people with low sight/low memory has demonstrated the feasibility of using such devices as a means of communication. Accordingly, a previous study in construction research investigated various parameters of tactile signals to develop a communicable system for potential application in construction hazard communication. However, the nature of construction limits the application of such devices to the body of construction workers, and it is important to understand sensor design parameters for improved communication, which has not been given significant attention yet. Therefore, this study aims to determine key design factors such as the number of motors, spacing between sensors and the layout of a tactile sensory system to be used for communicating construction hazards to workers. For this purpose, this study focused on identifying the number of motors based on extensive literature and the problem of construction safety as to hazard communication, determining the arrangement that allowed for effective delivery and perception of information with minimum effort. The researchers conducted two experimental studies: First, to determine the minimum spacing between vibration motors that allows for the identification of each individual motor with high accuracy; and second, to determine the layout of motors that is suitable for effective communication of multiple types of information. More importantly, the tactile-sensor configuration identified from this study allows the workers to learn the signal patterns easily in order to identify multiple types of information related to hazards. Using such a communication system on construction sites will assist in transmitting hazard-related information to workers, and thus, protect the lives of workers. Such wearable technologies enable the detection of individual-level hazards and prevent worker fatalities and severe injuries.
Application of an Improved Correlation Method in Electrostatic Gait Recognition of Hemiparetic Patients
Authors: Tian Shanshan , Li Mengxuan , Wang Yifei , Chen Xi
Published: June 2019

Hemiparesis is one of the common sequelae of neurological diseases such as strokes, which can significantly change the gait behavior of patients and restrict their activities in daily life. The results of gait characteristic analysis can provide a reference for disease diagnosis and rehabilitation; however, gait correlation as a gait characteristic is less utilized currently. In this study, a new non-contact electrostatic field sensing method was used to obtain the electrostatic gait signals of hemiplegic patients and healthy control subjects, and an improved Detrended Cross-Correlation Analysis cross-correlation coefficient method was proposed to analyze the obtained electrostatic gait signals. The results show that the improved method can better obtain the dynamic changes of the scaling index under the multi-scale structure, which makes up for the shortcomings of the traditional Detrended Cross-Correlation Analysis cross-correlation coefficient method when calculating the electrostatic gait signal of the same kind of subjects, such as random and incomplete similarity in the trend of the scaling index spectrum change. At the same time, it can effectively quantify the correlation of electrostatic gait signals in subjects. The proposed method has the potential to be a powerful tool for extracting the gait correlation features and identifying the electrostatic gait of hemiplegic patients.

Published: June 2019

A simple structure and easily fabricated displacement sensor was proposed and demonstrated based on a bending-induced fiber interferometer. In the design, the fiber interferometer was formed only by bending the single-mode fiber into a small U-shape without splicing, tapering, or heating pre-processing, which effectively reduces the complexity of the fabrication process, greatly enhances the mechanical strength of the sensor, and lowers the cost in the displacement sensing applications. The displacement sensing performances for the sensor with different bending radii of 3.3 mm, 4.4 mm, 5.0 mm, and 6.3 mm were investigated. Experimental results showed that the sensor had a good linear response, and for the bending radii of 3.3, 4.4, 5.0, and 6.3 mm, the proposed sensors showed high sensitivities of 134.3, 105.1, 120.9, and 144.1 pm/μm, respectively.
The Importance of Information Management in the Context of Industry 4.0: Evidence from the Kuyavian-Pomeranian Forbes Diamonds
Authors: Kuś Agnieszka , Pypłacz Paula
Published: June 2019

Currently, the role of information and of the tools facilitating its acquisition and processing is so significant that, in the economic nomenclature, there are already such concepts as an information civilization or information society. The aftermath of this state of affairs is the commercial breakthrough consisting of the enterprise’s success on the intellectual capital rather than the material one. This article aims to show the outline of the information management process and to determine how its components are used in companies. The first part of the paper is devoted to the description of information management concepts in enterprises and the functioning of organizational information systems. The second part of the study includes the results of original research carried out using the Computer-Assisted Web Interview (CAWI) method on the 70 Kuyavian-Pomeranian enterprises counted among the Forbes Diamonds 2018. An analysis of the obtained results indicates that the level of diversity of methods and frequencies of information channels used depends on the size of the entity, its capital structure, and the industry in which they operate. The primary sources of information for the surveyed companies are customers and competitors. The respondents agree that a well-functioning enterprise information system facilitates making decisions in the company and improves internal communication. The most frequently implemented development strategy in the analyzed companies is the market development strategy.
The Development of the Health and Social Care Sector in the Regions of the Czech Republic in Comparison with other EU Countries
Authors: Urbánková Erika
Published: June 2019

In this paper, the quantitative status of employees in the Health and Social Care sector in the Czech Republic is assessed, and the future development of the sector is predicted both for the Czech Republic as a whole, and for individual regions according to the NUTS3 classification. At present, labor market prognoses are created using the ROA-CERGE model, which includes the main professions in the Health and Social Care sector. This article expands the predictions by adding the regional level and using extrapolation of time series, and it identifies the regions important for the given sector and the labor force. The position of the Czech Republic with regard to selected professions in comparison with other countries of the European Union, i.e., its qualitative status, is also assessed in the paper. The following professions are assessed: general nurses and midwives (both with and without a specialization), physicians, and professional assistants. Healthcare workers do not manifest geographical mobility between regions and work primarily in the region where they live. Since the Czech Republic’s accession to the EU, staff working in key professions have been able to work under comparable conditions in any of the member states. The workforce flow depends, among other things, on its qualitative representation in the given country. To find groups of European countries with similar characteristics of quantitative coverage in selected professions in the Health and Social Care sector, cluster analysis is used to identify homogeneous clusters of countries, as of 2016. Secondary data was obtained from the Czech Statistical Office (CZSO) and the Information System (ISA+) of the National Institute of Education (NIE).

L'Education sentimentale : Le classement des scénarios

Pour bien comprendre la genèse de L'Education sentimentale, il est nécessaire d'identifier les documents qui correspondent à chaque stade de la longue préparation du roman. Connus depuis longtemps, les plans rudimentaires du Carnet 19 (1862) représentent l'embryon primitif du roman. Tandis que les plans rédigés en 1863 ont été perdus, les scénarios dans lesquels Flaubert établit les grandes lignes de son roman au cours du troisième stade préparatoire (1864) ont été conservés. Dans le volume (Bibl. Nat., NA.F. 17611) qui contient la plupart des scénarios du roman les folios 65-104 peuvent être classés comme des 'scénarios d'ensemble' ; écrits avant les autres scénarios, ils couvrent le roman entier. Par contre, les folios 1-64, d'une taille un peu plus grande, peuvent être classés comme des scénarios partiels puisqu'ils couvrent soit une partie entière du roman, soit un chapitre. Certains ont pu être rédigés avant septembre 1864 quand Flaubert a commencé à écrire son roman, d'autres ont été rédigés au fur et à mesure que le roman avançait.

Quant on se rappelle le texte définitif avec toutes ses incertitudes, toutes ses lacunes et toutes ses ambiguïtés, les scénarios peuvent surprendre. Il semble que Flaubert avait besoin de savoir exactement ce qui serait occulté, afin que le caché se voie -en filigrane -à travers l'obscurcissement progressif de l'oeuvre.
Des logements locatifs dans l'espace rural. L'exemple de la Haute-Normandie
Authors: Fruit Jean-Pierre
Published: June 2019

In France, during the last twenty years, a lot of new houses, mainly privately owned, have been built in the countryside, especially near the towns. As a consequence, 71 per cent of the rural households are owners of their home. Nevertheless, according to a common opinion, it is actually obvious that a large demand in rent-housing is not fulfilled by the offer. In order to check this hypothesis, the local authorities of Haute-Normandie carried on a study, in collaboration with the Geography Department of the Rouen University. Eight cantons have been selected among various types of rural areas, from suburban rural areas to "deep" countryside still largely inhabited by farmers.

In this framework, it has been established that the offer is quantitatively low, especially in council housing, and of poor quality in the predominant private sector. This inadequate offer is facing a strong demand, claiming for more and more comfortable homes. The demand proceeds mainly from young households with low incomes or from elderly retired people but also from teachers, civil servants and other wage-earners whose places of work sustain strong turnover and who can afford rather expensive rents. However, the imbalance between offer and demand leads to expensive rents, even for uncomfortable private houses.

With the help of vacant homes and disused buildings, it would be possible to enlarge the offer, but it would not be sufficient. It was necessary to built new houses for rent of good quality let at reasonable prices, with the help of the current developers of council-housing and also with the help of private developers. This last policy would be the more difficult to enforce. In fact, policies must be adapted to the diversity of rural areas.

Water erosion of arable land in the Pays de Caux

Despite moderate geographical (topographical, climatic) conditions, a large area of farmland in the Pays de Caux is today subject to run-off and erosion. The explanation would appear to tie in with the agricultural changes of recent decades. However, although the factors are not difficult to identify, the same effects can be produced by a variety of combinations.

From a long-term point of view, the present situation is the result of a process of readjustment to agricultural changes against a background of Holocene modifications, first natural and later manmade, of the Weichselian landscape. The problem is how to limit and control this process, given the regional socio-economic context.

A highly efficient porous rod-like Ce-doped ZnO photocatalyst for the degradation of dye contaminants in water
Authors: Hu Binjing , Sun Qiang , Zuo Chengyi , Pei Yunxin , Yang Siwei , Zheng Hui , Liu Fangming
Published: June 2019

A mild and simple method was developed to synthesize a highly efficient photocatalyst comprised of Ce-doped ZnO rods and optimal synthesis conditions were determined by testing samples with different Ce/ZnO molar ratios calcined at 500 °C for 3 hours via a one-step pyrolysis method. The photocatalytic activity was assessed by the degradation of a common dye pollutant found in wastewater, rhodamine B (RhB), using a sunlight simulator. The results showed that ZnO doped with 3% Ce exhibits the highest RhB degradation rate. To understand the crystal structure, elemental state, surface morphology and chemical composition, the photocatalysts were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscope (SEM) and inductively coupled plasma emission spectroscopy (ICP), respectively. The newly developed, robust, field-only surface integral method was employed to explore the relationship between the remarkable catalytic effect and the catalyst shape and porous microstructure. The computational results showed that the dipole-like field covers the entire surface of the rod-like Ce-doped ZnO photocatalyst and is present over the entire range of wavelengths considered. The optimum degradation conditions were determined by orthogonal tests and range analysis, including the concentration of RhB and catalyst, pH value and temperature. The results indicate that the pH value is the main influential factor in the photocatalytic degradation process and the optimal experimental conditions to achieve the maximum degradation rate of 97.66% in 2 hours are as follows: concentration (RhB) = 10 mg/L, concentration (catalyst) = 0.7 g/L, pH 9.0 and T = 50 °C. These optimum conditions supply a helpful reference for large-scale wastewater degradation containing the common water contaminant RhB.

Published: June 2019

The synthesis of conjugates of perylene diimide (PDI) and naphthalene diimide (NDI) modified with two benzo-21-crown-7 ethers (B21C7) are herein described. Their self-assembly behavior in various solvents was investigated particularly in aqueous medium, due to the recently discovered hydrophilic properties of B21C7 crown macrocycle. An unexpected fluorescence quenching phenomenon was observed in the PDI-B21C7 macrocycle conjugate in chloroform. The detailed UV–vis absorption and fluorescence spectra of these PDI/NDI derivatives in different solvents as well as their morphologies were investigated.
Optical Transient Object Classification in Wide-field Small Aperture Telescopes with a Neural Network
Authors: Jia Peng , Zhao Yifei , Xue Gang , Cai Dongmei
Published: June 2019

Wide-field small aperture telescopes are the workhorses of fast sky surveying. Transient discovery is one of their main tasks. Classification of candidate transient images between real sources and artifacts with high accuracy is an important step for transient discovery. In this paper, we propose two transient classification methods based on neural networks. The first method uses the convolutional neural network without pooling layers to classify transient images with a low sampling rate. The second method assumes transient images as one-dimensional signals and is based on recurrent neural networks with long short-term memory and a leaky ReLu activation function in each detection layer. Testing real observation data, we find that although these two methods can both achieve more than 94% classification accuracy, they have different classification properties for different targets. Based on this result, we propose to use the ensemble learning method to increase the classification accuracy further, to more than 97%.
Unusually Bright Single Pulses from the Binary Pulsar B1744–24A: A Case of Strong Lensing?
Authors: Bilous A. V. , Ransom S. M. , Demorest P.
Published: June 2019

We present a study of unusually bright single pulses (BSPs) from a millisecond pulsar in an ablating binary system, B1744−24A, based on several multiorbit observations with the Green Bank Telescope. These pulses come predominantly in time near eclipse ingress and egress, have intensities up to 40 times the average pulse intensity, and pulse widths similar to that of the average pulse profile. The average intensity, spectral index of radio emission, and the dispersion measure do not vary in connection with BSP outbursts. The average profile obtained from BSPs has the same shape as the average profile from all pulses. These properties make it difficult to explain BSPs via scintillation in the interstellar medium, as a separate emission mode, or as conventional giant pulses. BSPs from B1744−24A have similar properties to the strong pulses observed from the Black Widow binary pulsar B1957+10, which were recently attributed to strong lensing by the intrabinary material. We argue that the strong lensing likely occurs in B1744−24A as well. For this system, the sizes and locations of the lenses are not well constrained by simple 1D lensing models from Cordes et al. and Main et al. This partly stems from the poor knowledge of several important physical parameters of the system.
A Spectroscopic Study of a Rich Cluster at z = 1.52 with Subaru and LBT: The Environmental Impacts on the Mass–Metallicity Relation

We present the results of our near-infrared spectroscopic observations of a rich cluster candidate around a radio galaxy at z = 1.52 (4C65.22) with Subaru/MOIRCS and Large binocular telescope/LUCI. We observed 71 galaxies mostly on the star-forming main sequence selected by our previous broadband (photo-z) and narrowband Hα imaging observation in this cluster environment. We successfully confirmed the redshifts of 39 galaxies, and concluded that this is a gravitationally bound, real cluster at z = 1.517. Our spectroscopic data also suggest a hint of large-scale filaments or sheet-like three-dimensional structures crossing at the highest-density cluster core. By stacking the spectra to derive their average interstellar medium gas-phase metallicity based on the [N ii]/Hα emission line flux ratio, we find that the mass–metallicity relation (MZR) in the 4C65.22 cluster environment is consistent with that of Hα-selected field galaxies at similar redshifts. Our results suggest that the environmental impacts on the MZR is small at high redshifts, but a larger sample of high-z clusters and their member galaxies is still required to fully address the effect of environment as well as its cluster–cluster variation.

We hypothesised that the reduction in cardiorespiratory fitness (CRF) of individuals with less severe obesity is small or non-existent when the allometric rather than the ratio standard is used for the comparison. We aimed to evaluate the influence of obesity on CRF, and to compare peak VO2 using allometric corrections in asymptomatic adults with a wide range of body mass index. The results of 780 adults (age 41±13 years) who underwent cardiopulmonary exercise testing (CPET) were evaluated. Participants were stratified according to body mass index (BMI): normal weight (n=227), overweight (n=198), and obese class 1 (n=155), 2 (n=131), and 3 (n=69). After cardiovascular risk assessment, the participants underwent CPET on a treadmill ramp protocol. The allometric exponents calculated were 0.60 and 0.62 for obese and non-obese groups respectively, with no significant differences. After using BMI strata in a multivariate analysis of covariance, we found an allometric exponent of 0.65. Peak VO2 using ratio standards significantly declined among all stratified groups. After allometric correction, peak VO2 remained significantly reduced only in women with obesity class 3 and men with obesity classes 2 and 3. When ratio standards were used to compare peak VO2, the effect of obesity on CRF was overestimated. Allometric correction of peak VO2 is more reasonable, and should be adopted as a routine for CPET.
An Interdisciplinary Collaboration: Development of an Opioid Crisis Elective for BSN and RN-to-BSN Students
Authors: Whelpley Robin , Feurer Amy
Published: June 2019

Background:

The nation's opioid crisis has caused the nursing profession to examine pain management practices, including assessment of pain, diagnosis, and treatment. Nursing programs have the opportunity to play a vital role in addressing the opioid crisis by enhancing the pain management content in their curriculum.

Method:

A nursing elective course was designed and implemented that allowed nursing students to examine appropriate pain assessment, the role of the nurse, best practices in pharmaceutical treatment, and attitudes and biases that may exist. The course was designed by a pharmacist and co-taught with a nurse practitioner.

Results:

The course consisted of 25 nursing students mixed from the baccalaureate nursing (BSN) degree and RN-to-BSN programs. There was a success rate of 100% and an overall satisfaction rate of 97%.

Conclusion:

This course met several goals: (a) the need for an elective; (b) achievement of two nursing program outcomes; (c) increased nursing student knowledge relating to appropriate pain management using an interdisciplinary approach; and (d) camaraderie created between school programs.

Trabalhando pelos bons vinculamentos: Reflexões antropológicas sobre o ofício das doulas
Authors: Tempesta Giovana Acacia
Published: June 2019

O artigo trata de um aspecto central do trabalho realizado pelas doulas e educadoras perinatais – profissionais que prestam apoio físico, emocional e informacional à mulher durante a gestação, o parto e o puerpério –, qual seja, a habilidade de estabelecer e sustentar um certo tipo de vinculamento com a mulher. A partir da pesquisa com doulas alinhadas à medicina baseada em evidências científicas que atuam em Brasília (DF), proponho que certos conceitos, imagens e afetos mobilizados por elas tensionam e desafiam a hegemonia dos valores que sustentam os protocolos adotados pelas instituições médico-hospitalares. O conceito de vinculamento (Latour, 2016) nos ajuda a perceber que, sob o aparente contrassenso de uma pedagogia do instinto feminino aplicada pelas doulas, viceja uma modalidade diferencial de cuidado, que pode ser condensada na expressão “mulheres que apoiam mulheres”, e que, em alguma medida, desestabiliza as tendências liberais, individualistas e hedonistas presentes no ideário da “humanização” do parto.

Authors: Pinheiro Patrícia dos Santos , Menasche Renata , Magni Claudia Turra , Machado Carmen Janaina
Published: June 2019

Este trabalho busca mostrar processos criativos no âmbito da agricultura agroecológica da região de Pelotas, Rio Grande do Sul, seguindo suas forças e fluxos e analisando, sob um olhar antropológico, tecnologias, invenções e adaptações na produção. A partir de pesquisa etnográfica realizada entre 2015 e 2016, foram reunidos relatos concernentes a atividades produtivas e relação entre novidades e valorização de práticas tradicionais, expandindo as possibilidades de trabalhar com e não somente na terra. Esses relatos foram produzidos, sobretudo, pela família Schiavon, agricultores da localidade de São Manoel, cuja sintonia com plantas e animais, com técnicas empregadas e transformadas e com tecnologias criadas e multiplicadas evidencia um engajamento com o ambiente que extrapola os limites de sua propriedade rural.
Contração, expansão e a dialética do parentesco Tukano
Authors: Leirner Piero
Published: June 2019

Este artigo pretende explorar algumas hipóteses que dizem respeito à dinâmica de crescimento e fragmentação de certos clãs tukano (alto Rio Negro, Brasil), sobretudo aqueles que são tomados nativamente como “médios”. Tomando como base o entrelaçamento entre dois aspectos de sua organização social, o sistema de casamento (preferencialmente FZD) e a hierarquia, serão discutidos, através de elementos já levantados pela literatura e de sugestões nativas, movimentos de “torção” de regras e de contrapesos a estas. Como resultado, a aposta aqui vai na direção de uma dialética entre expansão e contração do regime de alianças regional.
Os ecos sem voz: Uma década de falas sem escuta no Congresso Nacional Ainda sobre o “infanticídio indígena”
Authors: Holanda Marianna Assunção Figueiredo
Published: June 2019

Este ensaio reflete sobre os 13 anos em que o outrora PL 1057/2007, atual PLC 119/2015, tramitam no Congresso Nacional, abordando suas consequências na mídia, na opinião pública e na vida dos povos indígenas no Brasil. Trata-se de proposições legislativas que visam normatizar e criminalizar o quem vêm chamando de “infanticídio indígena”. Este texto é, em parte, auto-etnográfico – na medida em que participei de muitos dos eventos relatados, seja como pesquisadora, seja como funcionária pública ou ainda como consultora de organismos internacionais – em parte etnográfico, na medida em que trago relatos de indígenas, indigenistas e funcionários públicos sobre o tema, obtidos ao longo das diversas atuações profissionais mencionadas e, por fim, o texto dialoga com pesquisa documental e bibliográfica. Este encontro de perspectivas no tempo e no espaço me conduziu a esquadrinhar o racismo institucional que cria o termo “infanticídio indígena” a partir da presença desigual e nada plural de perspectivas evangélicas como eixo estrutural das atuações legislativas e judiciárias - carregando consigo o signo do universal e, portanto, “neutro”.
Transformação agrária e desapropriação de terras indígenas em Mato Grosso (1940-1960): O caso da reserva Kadiwéu
Authors: Flores José Manuel
Published: June 2019

Este artigo aborda o processo de desapropriação das terras indígenas no sul do estado de Mato Grosso, em meados do século XX, focando no caso particular da reserva Kadiwéu, criada em 1900, e localizada no município de Porto Murtinho, no atual estado do Mato Grosso do Sul. A problemática é colocada no contexto do avanço da fronteira e da transformação na estrutura agrária mato-grossense entre os anos de 1940 a 1960, período crucial na titulação privada de terras e, consequentemente, da apropriação de terras indígenas no sul do estado. No final deste período, uma parte significativa da reserva havia passado ao controle de pecuaristas da região, através de um sistema de arrendamentos estabelecido pelo Serviço de Proteção aos Índios (SPI), peça chave no processo de integração das terras à esfera produtiva em formação em claro detrimento da população Kadiwéu no estado.
Unidade e diferença: os Ye’kwana e suas relações com a fronteira binacional
Authors: Andrade Karenina Vieira
Published: June 2019

Neste artigo reflito sobre a constituição de uma unidade sociológica ye’kwana e da consequente matriz de relação destes com seus Outros, à luz do conceito nativo de weichö, que traduzo aqui como “modo de vida”. O exame de como o “modo de vida” ye’kwana se constitui e opera é fundamental para se compreender a relação que estes estabelecem com a fronteira internacional que corta seu território tradicional, bem como as relações entre as comunidades ye’kwana situadas em território brasileiro e venezuelano.
Unir para além da fronteira: Um esboço da etnopolítica transnacional ashaninka
Authors: Pimenta José
Published: June 2019

Este artigo discute as alianças intraétnicas transfronteiriças entre os Ashaninka do rio Amônia do Alto Juruá brasileiro e os Ashaninka do Peru, principalmente da região do Ucayali. Apresenta o contexto histórico que levou à demarcação dos limites internacionais entre Brasil e Peru na região do Alto Juruá e discute os diversos significados da fronteira para os Ashaninka do rio Amônia. Mostra que as alianças transfronteiriças recentes que procuram reunir esse povo indígena para além da fronteira dos Estados-nações são, sobretudo, uma resposta aos projetos governamentais de desenvolvimento e integração binacional e às atividades ilegais em curso na região. Embora se considerem um povo único, as alianças intraétnicas binacionais ashaninkas não revelam qualquer aspiração à independência como Estados, nem negam as identidades nacionais. Elas devem ser vistas, sobretudo, como uma estratégia política na defesa de seus territórios e de seus direitos diante das ameaças externas.
Como descrever uma “onda”? Uma abordagem metodológica para a etnografia de um movimento
Authors: Biondi Karina
Published: June 2019

Em 2012, ocorreu no Estado de São Paulo uma “onda de violência”, atribuída a um confronto entre o Primeiro Comando da Capital (PCC) e a polícia. Após anos de queda no número de homicídios, a capital paulista apresentou um aumento de 40% com relação ao ano anterior. A pesquisa que origina este artigo foi realizada justamente durante esse período e se viu diante das dificuldades de, por um lado, etnografar uma “onda” e, por outro, se inserir em um debate cujos termos já estavam definidos de antemão. Este artigo aborda as questões implicadas na tentativa de se etnografar um movimento e expõe uma abordagem teórico-metodológica formulada face a essa experiência, bem como seus desenvolvimentos. A partir da exposição de situações de pesquisa, das dificuldades que impõem e dos recursos teórico-metodológicos acionados, procura-se abordar também a relação entre os materiais etnográficos e o conhecimento acadêmico produzido sobre eles.
Supply Chain Efficacy in Relief Delivery
Authors: Baporikar Neeta , Atshipara Frans
Published: June 2019

Supply chain efficacy in disaster relief operations is crucial as disaster in any form brings grief and suffering. It also leads to colossal losses for those effected. The purpose of this study is to evaluate the challenges faced by the supply chain during the handling of disaster relief operations, namely drought. Adopting mixed research method involving both qualitative and quantitative, the focus is on performance of the supply chain in an organisation and residents of one of the most affected constituencies as a case study. Findings reflect that inadequate financial resources, restrictions on transport and difficulties associated with planning for the initial relief requirements of a distressed community are the main challenges for supply chain effectiveness in distribution the relief material. The strategies proposed, and recommendation made could be useful in improved supply chain for the effective handling of drought relief distribution and putting systems in place to the area of study and could help to align procedures for disaster response and aid in relief strategies.
Barriers to Effective Communication and Stakeholder Management in Project Environments and How to Overcome These Barriers
Authors: Galli Brian J.
Published: June 2019

This study sought to investigate the prominent barriers to effective communication and stakeholder management in project teams. Specifically, this study examined the role of management frameworks currently utilized by organizations and their efficiency in supporting team collaboration, conflict management, and stakeholder management in project environments. The study utilized a two-prong research methodology to identify and to analyze current literature related to the scope and objective of this study. The study first deployed an exploratory and unstructured literature review and then a structured literature review to identify the pool of relevant articles and content. A systematic review was then performed to reduce the body of literature down to the critical few that could serve as the basis for the study's analysis. The results revealed the inadequacies of management frameworks in promoting healthy relationships between project managers and stakeholders. Furthermore, the study exposes a gap between formal communications planning, the actual execution, the implementation of the plan, and the poor implementation of organizational processes. The results also show the common types of conflict, the positive and negative effects that these have on project environments, project success, and the critical success factors in stakeholder management. In addition to identifying barrier and shortcomings, this article sheds light on improvement areas that will have the most significant effect on project success. The literature synthesis reveals the importance of soft skill in communication management. The results suggest that much work remains to be done by the organization to train and prepare managers in building relationships and developing soft skills. The literature has demonstrated that perception, values, team cohesion, the willingness to share, trust, and healthy relationships are most influential in project success, but in practice, the latter is not applied. In conclusion, this area needs improvement and further investigation.
A New Strategy Based on GSABAT to Solve Single Objective Optimization Problem
Authors: Sattar H.A. , Cheetar Alaa , Tareq Iraq
Published: June 2019

This article proposes a new strategy based on a hybrid method that combines the gravitational search algorithm (GSA) with the bat algorithm (BAT) to solve a single-objective optimization problem. It first runs GSA, followed by BAT as the second step. The proposed approach relies on a parameter between 0 and 1 to address the problem of falling into local research because the lack of a local search mechanism increases intensity search, whereas diversity remains high and easily falls into the local optimum. The improvement is equivalent to the speed of the original BAT. Access speed is increased for the best solution. All solutions in the population are updated before the end of the operation of the proposed algorithm. The diversification feature of BAT has solved the problem of weakness in diversity observed in the algorithm by applying the parameters used in BAT. Moreover, balance is achieved through the intensification properties of the algorithms.
