Transforming the conditions of medical practitioners’ professional activities in the process of the healthcare service optimization
Authors: Shilova Liudmila S.
Published: July 2019

Today, medical administration assesses any practitioner’s performance efficiency based on the revenue they bring to the medical establishment. The consequences of the substitution of such traditional concepts as “patient”, “doctor” and “medical care” pursuant to the market approach to the medical function by “client”, “service provider” and “medical services” have been fully revealed. Following market paradigm, meaning that the “customer is always right”, patients have become more demanding of practitioners’ work. Medical practitioners under the conditions of overloading and overscheduling, strict regulations of the relationship with the medical establishment authority and insurance companies make mistakes more often. The main instrument for evaluating medical activities is multilayered legal documents, generated by various medical management entities and poorly coordinated with each other. Meanwhile, control practice follows its own rules and laws, and the complexity of the instrument makes no obstacle for the inspectors. Among insurers and officials there has developed a strong conviction in the physicians’ guilt, and that they a priori deserve criminal sentence. This conviction has been replicated by the media (for which such sort of materials helps to raise ratings according to the laws of the yellow press), and it has become shared by society, in particular, by patients. The number of patients’ complaints to the Investigative Committee of the Russian Federation has been increasing rapidly. In response to the “patients’ terrorism” practitioners have adopted a strategy of “protective medicine”, minimizing the risks of treatment to the detriment of its effectiveness. The established practice of doctor-patient relationship is equally harmful to both of them. Traditional professional medical values have turned out to be in conflict with the new requirements of the medical institution authorities caused by the commercialization of the medical care. Although most practitioners have the strength to overcome the crisis of workplace values due to the humanistic component of their profession, their medical activity is accompanied by dissatisfaction and burnout. Healthcare service optimization has resulted in strained relations between patients and healthcare providers.

Published: July 2019

Objetivo: Comparar los niveles enzimáticos de lactato deshidrogenasa (LDH) en la saliva según la condición periodontal. Material y métodos: Estudio descriptivo, transversal. Se incluyeron 40 pacientes entre 23 y 73 años de edad, de una clínica especializada en odontología. Hubo 10 pacientes en cada grupo: uno control (periodontalmente sanos) y tres de estudio. Las muestras de saliva no estimulada (2 ml) fueron recogidas en frascos para muestra de esputo, directamente de la boca; se trasladaron a tubos Eppendorf de 2 ml y se centrifugaron a 300 rpm por 10 minutos. Para evaluar la actividad enzimática, fueron colocados en el analizador automático “Vitalab Selectra II” (vital cientifi c, Holanda) con el reactivo LDH-P UV AA líquido, para muestras de suero o plasma. El dinucleótido de nicotinamida y adenina (NADH) consumido, fue directamente proporcional a la actividad de LDH en la muestra de saliva. Los datos se analizaron con las pruebas de Kruskal-Wallis y post hoc de Dunn-Bonferroni. Resultados: Se encontró diferencias significativas en los niveles de LDH entre los pacientes con periodontitis crónica generalizada frente a los periodontalmente sanos y en fase de mantenimiento (p<0,01). También hubo diferencia significativa (p=0,006) entre los valores de LDH de los pacientes con periodontitis crónica localizada y los periodontalmente sanos. Conclusiones: Los niveles enzimáticos de LDH están disminuidos en los pacientes en fase de mantenimiento periodontal respecto a los pacientes con periodontitis crónica generalizada, así mismo estos valores son muy cercanos a los pacientes periodontalmente sanos y con periodontitis crónica localizada.

Authors: Balensiefer Vicenzi Cristina , Giotti Marostega Milena , Sawazaki Renato , De Conto Ferdinando
Published: July 2019

Os osteomas geralmente são lesões solitárias, de crescimento lento e assintomáticas. Os locais de ocorrência mais comuns são o corpo da mandíbula e o côndilo, mas quando envolvem esta região podem causar alterações na oclusão do paciente, desvio progressivo e lento de linha média, assim como aumento do volume facial acompanhado de dor e limitação de abertura bucal. Cerca de 90% dos pacientes portadores da Síndrome de Gardner apresentam anormalidades esqueléticas, fazendo os osteomas as lesões mais frequentes e de maior ocorrência em seios paranasais e nos maxilares. O objetivo deste trabalho é relatar o caso clínico de uma paciente do gênero feminino, portadora de Síndrome de Gardner com osteoma localizado em côndilo mandibular esquerdo que, devido aos sintomas relatados pelo paciente, foi submetida à ressecção cirúrgica por meio de acesso intra oral para melhor abordagem da lesão e que evoluiu para a solução da sintomatologia apresentada como queixa principal quando procurou o serviço de Cirurgia e Traumatologia Buco-maxilo-facial.

Low-Power Detection of Food Preservatives by a Novel Nanowire-Based Sensor Array
Authors: Zappa Dario
Published: July 2019

Food preservatives are compound that are used for the treatment of food to improve the shelf life. In the food industry, is necessary to monitor all processes, for both safety and quality of the product. An electronic nose (or e-nose) is a biomimetic olfactory system that could find numerous industrial applications, including food quality control. Commercial electronic noses are based on sensor arrays composed by a combination of different sensors, which include conductometric metal oxide devices. Metal oxide nanowires are considered among the most promising materials for the fabrication of novel sensing devices, which can enhance the overall performances of e-noses in food applications. In the present work, is reported the fabrication of a novel sensor array based on SnO2, CuO and WO3 nanowires deposited on top of commercial μHPs, provided by ams Sensor Solutions Germany GmbH. The array was tested for the discrimination of four typical compounds added to food products or used for their treatment to increase the shelf life: ethanol, acetone, nitrogen dioxide and ozone. Results are very promising: the sensors array was able to operate for long time consuming less than 50mW for each single sensor, and PCA analysis confirms that the device was able to discriminate between different compounds.

Published: July 2019

Heat stress occurring during the reproductive stage of wheat has a detrimental effect on productivity. A durum wheat core set was exposed to simulated terminal heat stress by applying plastic tunnels at the time of flowering over two seasons. Mean grain yield was reduced by 54% compared to control conditions, and grain number was the most critical trait for tolerance to this stress. The combined use of tolerance indices and grain yield identified five elites: Kunmiki, Berghouata1, Margherita2, IDON37-141, and Ourgh. The core set was also subjected to genome wide association study using 7,652 polymorphic SNPs markers. The most critical genomic regions were identified in association with spike fertility and tolerance indices on chromosome 1A, 5B and 6B. Haplotype analysis on a set of 208 elites confirmed that lines that carried the positive allele at all three QTLs resulted in a yield advantage of 8% when field tested under daily temperatures above 31° C. Two of the QTLs were successfully validated into KASP markers and explained >10% of the phenotypic variation for an independent elite germplasm set. These genomic regions can now be readily deployed via breeding to improve resilience to climate change and increase productivity in heat-stressed areas.
Wood Charcoal Fuel Resilience in Kampala Capital City; Charcoal in the Water Energy and Food Urban Nexus
Authors: Bamwesigye Dastan , Doli Azdren
Published: July 2019

Kampala is the capital city of Uganda. Over the years the population growth in the city has more than doubled, and this has increased the demand for energy. However, electricity and gas are not only limited in supply but are also expensive for the majority of the households hence the use of charcoal remains the main source of energy. There is little known about the energy situation in big cities of Africa, and Kampala is not an exception. Therefore, we examine the urban nexus amidst energy poverty, vulnerability, and resilience with a focus on; the role of charcoal in the urban Nexus in Kampala Uganda. Literature review and content analysis of scientific materials such as journal articles and reports were done. Charcoal fuel in Kampala and surrounding urban areas does not only facilitate cooking meals and boing water for over 95% of households but also a source of livelihood for many women in the nexus. This process impacts not only on energy use but also the entire water, energy, and food system in the urban nexus. Even though charcoal fuel doubles as a source of household income, it is greatly responsible for most deforestation. Furthermore, charcoal production also accounts for prolonged droughts hence impacting on water and food supply in the nation. Therefore, we propose subsidizing alternatives such as gas and electricity to reduce the complete reliance on charcoal.

Published: July 2019

Abstract Background: Chronic pain is common among older adults and is associated with adverse physical and psychological outcomes. Given the expected burden and limited healthcare resources, an innovative and cost-effective method to manage chronic pain should be developed. Peer volunteers (PVs) have been used as an affordable alternative to professional services to help patients manage their chronic conditions including pain with success and acceptance. The aim of this paper is to explore the experiences and perceptions of PVs in a peer-led pain management program among nursing home residents. Methods: This longitudinal study formed part of a wider research study, a clustered randomised controlled trial, which investigates the effectiveness of a 12-week peer-led pain management program (PAP) in relieving chronic pain and enhancing pain self-efficacy among nursing home residents. Quantitative data were collected from questionnaires (demographics, pain situation and pain knowledge) for all PVs. Qualitative data (PVs’ experiences in leading the PAP, their perceived benefits, limitations and barriers encountered, its usefulness to the participants and recommendations for improving the PAP) were collected from focus group for a selected sample at baseline (before attending the training) and at week 12 (upon completion of the PAP). Data were analysed using the Statistical Package for Social Sciences and NVivo 8. Results: A total of 46 PVs were recruited (34 female, 74%), with mean±SD age of 61.0±5.1 years. Thirty-one PVs reported to have chronic pain. Before the training, self-rated pain knowledge was 39.1±20.4 (maximum 100 points). When actual pain knowledge was assessed, a mean pain knowledge score of 86.1±10.6 points was found. There was a significant difference between the self-rated pain knowledge and the pain knowledge score (p<0.001). PVs reported to have improvement in their knowledge and skills. No PVs reported negative comments regarding their role in the PAP, although experienced barriers such as communication, space and privacy were reported. Conclusions: This study provides further evidence that peer-led pain management program is feasible. Barriers identified may benefit the design and planning of future PAP. Trial registration: ClincalTrials.gov (NCT03823495), 30 January 2019. (Retrospectively registered).

Published: July 2019

Cyanobacteria are an ancient lineage of slow-growing photosynthetic bacteria and a proliﬁc source of natural products with diverse chemical structures and potent biological activities and toxicities. The chemical identiﬁcation of these compounds remains a major bottleneck. Strategies that can prioritize the most proliﬁc strains and novel compounds are of great interest. Here, we combine chemical analysis and genomics to investigate the chemodiversity of secondary metabolites based on their pattern of distribution within some cyanobacteria. Planktothrix being a cyanobacterial genus known to form blooms worldwide and to produce a broad spectrum of toxins and other bioactive compounds, we applied this combined approach on four closely related strains of Planktothrix. The chemical diversity of the metabolites produced by the four strains was evaluated using an untargeted metabolomics strategy with high-resolution LC-MS. Metabolite proﬁles were correlated with the potential of metabolite production identified by genomics for the different strains. Although, the Planktothrix strains present a global similarity in term biosynthetic cluster gene for microcystin, aeruginosin and prenylagaramide for example, we found remarkable strain-specific chemo-diversity. Only few of the chemical features were common to the four studied strains. Additionally, the MS/MS data were analyzed using Global Natural Products Social Molecular Networking (GNPS) to identify molecular families of the same biosynthetic origin. In conclusion, we present an efﬁcient integrative strategy for elucidating the chemical diversity of a given genus and link the data obtained from analytical chemistry to biosynthetic genes of cyanobacteria.

Published: July 2019

Background: Cervical myelopathy (CM) is a common cause of morbidity and disability in patients with mucopolysaccharidosis (MPS) and, therefore, early detection is crucial for best surgical intervention and follow-up. Transcranial Magnetic Stimulation (TMS) non-invasively evaluates the conductivity along the cortico-spinal tract, also allowing preclinical diagnosis and monitoring. Methods: motor evoked potentials (MEPs) to TMS were recorded in a group of 8 patients with MPS-related CM. Responses were obtained during mild tonic contraction through a circular coil applied over the “hot spot” of the first dorsal interosseous and tibialis anterior muscles, bilaterally. Central motor conduction time was estimated as the difference between MEP cortical latency and the peripheral motor conduction time by cervical or lumbar magnetic stimulation. Peak-to-peak MEP amplitude to cortical stimulation and right-to-left difference of each parameter were also measured. Results: TMS revealed abnormal findings from both upper and lower limbs compatible with axonal damage and demyelination in 6 of them. Notably, a subclinical cervical spinal disease was detected before the occurrence of an overt CM in two patients, whereas TMS signs compatible with a CM of variable degree persisted despite surgery in all treated subjects. Conclusions: TMS screening should be performed in MPS patients, before and after surgery.

In the implementation of thermal enhanced oil recovery (TEOR) techniques, the temperature impact on relative permeability in oil - water systems is of special concern. Hence, developing a fast and reliable tool to model the temperature effect on two-phase oil - water relative permeability is still a major challenge for precise studying and evaluation of TEOR processes. To reach the goal of this work, two promising soft-computing algorithms, namely Group Method of Data Handling (GMDH) and Gene Expression Programming (GEP) were employed to develop reliable, accurate, simple and quick to use paradigms to predict the temperature dependency of relative permeability in oil - water systems (Krw and Kro). To do so, a large database encompassing wide-ranging temperatures and fluids/rock parameters, including oil and water viscosities, absolute permeability and water saturation, was considered to establish these correlations. Statistical results and graphical analyses disclosed the high degree of accuracy for the proposed correlations in emulating the experimental results. In addition, GEP based correlations were found to be the most consistent with root mean square error (RMSE) values of 0.0284 and 0.0636 for Krw and Kro, respectively. Lastly, the comparison of the performances of our correlations against those of the preexisting ones indicated the large superiority of the introduced correlations compared to previously published methods. The findings of this study can help for better understanding and studying the temperature dependency of oil - water relative permeability in thermal enhanced oil recovery processes.

Published: July 2019

Lemon balm extracts by dry plant material of Melissa officinalis were tested against their efficacy against for different fungal species Alternaria alternata, Fusarium oxysporum, Aspergillus flavus and Beauveria bassiana. The aqueous phase of the extract was evaluated for antioxidant, antifungal and also anti-aflatoxigenic activity. A synergism evaluation was also performed concerning, the small quantity of lemon balm polar essential oil compounds extracted into the infusion and the water soluble compounds in the extract. The experiments were conducted in solid cultures and the growth inhibition was demonstrated by measuring mycelial diameter. Additionally, the effect on conidia production was also demonstrated. Lemon balm was also used for in situ test on Pistachia vera seed against Aspergillus flavus growth and aflatoxin production. Results revealed enhancement of fungal growth by lemon balm extracts however total inhibition of aflatoxins production on Pistachia vera seeds was observed, and both actions were tried to attributed to volatile and water soluble compounds identified based on GC/MS, HPLC/DAD and LC/MS, and the observed antioxidant activity. Volatile and water - soluble compounds found to be in absolute synergism in mycelium growth enhancement and the observed anti-aflatoxigenic activity addressed to the high antioxidant activity observed and synergistic action between the other water soluble phenolic compounds identified in the extract. The findings of this study underline the high biological active potential of lemon balm extracts under various screening test since for the first time full phytochemical analysis of lemon balm extracts.

Published: July 2019

This study analyses uncertainties associated with the annual cycle of West African rainfall characteristics in 15 simulations of the Coupled Model Intercomparison Project phase 5 (CMIP5) over the Sahel and Guinean regions. Indices based on daily rainfall such as the frequency and the ntensity of wet days, the consecutive dry days (CDD) and wet days (CWD), the 95th percentile of daily rainfall (R95) and its contribution to the umulative monsoon rainfall (R95PTOT) have been assessed. Over both regions, TRMM, GPCP and CHIRPS observational datasets provide very consistent results on the annual cycle of precipitation but less so on the frequency of wet days. Conversely, higher uncertainties are noted on the intensity of wet days over both study areas, particularly over the Guinean region. Overall, CMIP5 simulations present much higher uncertainties in the representation of the mean precipitation climatology, often provide too early (late) onset dates over the Sahel (the Guinean region) and overestimate rainfall during the early and late monsoon phases. These errors do not compensate at the annual scale nor when considering West Africa as a hole. Results also reveal that over the Guinean region, the difficulty of models to represent the annual structure of the mean precipitation strongly involves biases in the representation of the annual cycle of the frequency of wet days. We found strong uncertainties in the simulation of the CWD and he CDD over both areas. Conversely for R95p and R95PTOT, the ncertainties in CMIP5 models appear somewhat weaker, but the magnitude f R95 is largely underestimated in most models.

Published: July 2019

This article is about school evaluation. The objective was to explain critically the mediating relationships between educational evaluation and the production of school knowledge from the perspective of the Dialectical Historical Materialism. With this interest, a documentary analysis was made, obtaining as result four explanatory categories: production, subsumption, distribution and exchange of knowledge, which form a concrete totality with distinctions and antagonistic relationships between them, limited by their opposite. It is concluded that the evaluation as a mediating form lacks antagonistic pair and consequently of control by opposition, emerging from the school daily as autonomous and sovereign entity, oppressive of school subjects.

Published: July 2019

Induction of jasmonate-mediated plant defense against insect herbivory is initiated by a combination of both, mechanical wounding and chemical factors. In order to study both effects independently on plant defense induction, SpitWorm, a computer-controlled device which mimics the damage pattern of feeding insect larvae on leaves and, in addition, can apply oral secretions (OS) or other solutions to the ‘biting site’ during ‘feeding’, was developed and evaluated. The amount of OS left by a Spodoptera littoralis larva during feeding on Phaseolus lunatus (lima bean) leaves was estimated by combining larval foregut volume, biting rate, and quantification of a fluorescent dye injected into the larvae’s foregut prior to feeding. For providing OS amounts by SpitWorm equivalent to larval feeding, dilution and delivery rate were optimized. The effectiveness of SpitWorm was tested by comparing volatile organic compounds (VOC) emissions of P. lunatus leaves treated with either SpitWorm, MecWorm or S. littoralis larvae. Identification and quantification of emitted VOCs revealed that SpitWorm induced a volatile bouquet that is qualitatively and quantitatively similar to herbivory. Additionally, RT-qPCR of four jasmonic acid responsive genes showed that SpitWorm, in contrast to MecWorm, induces the same regulation pattern as insect feeding. Thus, SpitWorm mimics insect herbivory almost identical to real larvae feeding.

Published: July 2019

Background: Reelin is a large extracellular glycoprotein secreted by Cajal–Retzius cells and has a main role during brain development, especially in neuronal migration. Reelin is comprised of N-terminal F-spondin like domain, eight tandem repeats, and a highly conserved basic C-terminal region (CTR). The CTR main role in the secretion of Reelin has been investigated by advertently inducing deletion in whole or a part of this region; however, the role of CTR point mutations on the secretion of Reelin is shrouded in mystery. Materials and Methods: In this study, we performed experimental analyses on a subregion of Human Reelin containing 5th and 6th repeats (R5-R6), a part of 8 th repeat and the CTR which were amplified from cDNA of K562 and HEPG2 cells and cloned into a mammalian expressional plasmid (pVP22/myc-His). Bioinformatics investigation was performed on the CTR at both level of nucleotide and amino acid as well as mutant type. Random mutagenesis by error-prone PCR method was utilized to induce mutation in the CTR. The secretion efficiency of recombinant wild-type and mutant Reelin constructs compared in cell lysate and supernatant isolated from the transiently transfected HEK 293T cells using 6XHistag ELISA method. Results: In-vitro study demonstrated that the CTR alteration(S3440P) leads to impairment of Reelin secretion even after overexpression. Conclusions: Our results indicate that S3440P substitution in highly conserved structure of the CTR has an important effect on Reelin secretion.

Published: July 2019

O objetivo deste artigo é a apresentação de um método para avaliação dos fatores de impacto da produtividade na soldagem de tubulações industriais de aço-carbono soldadas com o processo Eletrodo Revestido. A metodologia utilizada baseia-se na simulação de Monte Carlo e em dados de produtividade coletados em obra gerenciada pela Petrobras na Refinaria Duque de Caxias (REDUC). A ferramenta utilizada é o “software” @Risk6.1 (2013), adaptado para avaliação da produtividade. Este “software” dispõe de recurso para elaboração do gráfico de tornado, através do qual se realiza a análise de sensibilidade, permitindo a detecção das atividades e eventos de maior impacto na produtividade. Os resultados obtidos demonstram a viabilidade da utilização do método, tanto para avaliação dos fatores de impacto na produtividade do procedimento de soldagem, a que se denomina produtividade intrínseca, quanto para a produtividade global, na qual também se consideram os tempos improdutivos, em que a soldagem se encontra paralisada em decorrência de algum evento. A metodologia adotada permite avaliar quais as atividades de maior impacto na produtividade da soldagem, possibilitando a seleção das ações que devem ser priorizadas com vistas a sua melhoria.

Authors: Pinto Nathalia Mina , Luiz Franck Alegre , Kempner-Moreira Fernanda
Published: July 2019

O Mapeamento de Fluxo de Valor (MFV) é uma ferramenta considerada como ponto inicial para a manufatura enxuta, sendo responsável pela identificação dos variados tipos de desperdícios existentes em uma organização e tornando visíveis as operações que agregam valor ao produto, fornecendo a possibilidade de melhorias contínuas. Este artigo tem como objetivo analisar o processo de fabricação do polipropileno em uma indústria recuperadora de termoplásticos localizada no sul de Santa Catarina por meio do MFV, identificando as contribuições específicas geradas pela ferramenta, que evidenciam os diferentes tipos de desperdícios e melhoram o entendimento do processo por inteiro. O artigo se utilizou do método estudo de caso, fundamentado através de pesquisas bibliográficas. Os resultados demostraram que o MFV indicou algumas mudanças e, com um investimento relativamente baixo em um novo equipamento, permitirá a redução do lead time de cada tonelada produzida, redução do tempo de ciclo em dois setores, diminuição dos tempos ociosos dos operadores, redução de estoques intermediários, redução na movimentação por meio de empilhadeiras e aumento do índice OEE, trazendo grandes vantagens no processo produtivo.

В прибрежной акватории Юго-Западного Крыма летом 2013 г. изучены видовой состав и количественные показатели мезо-, макро- и ихтиопланктона, а также питание личинок рыб. В ихтиопланктоне обнаружены икра и личинки 33 видов рыб из 24 семейств, что вдвое превысило показатели 1990-х гг. В мае 2013 г. в прибрежной акватории Севастополя наблюдался результативный нерест хамсы, которому способствовали благоприятная температура воды в море (+21 °C) и хорошие кормовые условия. Наибольшее количество летненерестующих видов зарегистрировано в июне при температуре поверхностной воды +22,7 °C. Численность икры рыб в 2013 г. увеличилась по сравнению с таковой в 2000 г. в 3,4 раза, личинок ― в 2,3 раза, что связано с их большей выживаемостью при улучшившихся условиях питания в результате относительно высокой численности зоопланктона с преобладанием мелкоразмерной фракции и доминированием в ней ювенильных стадий копепод. Другими факторами, улучшившими состояние кормовой базы личинок, были низкая численность гребневика Mnemiopsis leidyi A. Agassiz, 1865 и его слабое воздействие

Выполнена оценка уровней концентрации активности альфа-излучающих изотопов 239+240Pu в поверхностном слое (0–5 см) донных отложений десяти солёных озёр Крымского полуострова из четырёх географических групп. Установлено, что максимальные значения 239+240Pu характерны для донных осадков озёр морского происхождения из разных географических групп: оз. Кызыл-Яр ― (419 ± 27), оз. Джарылгач ― (443 ± 24), оз. Тобечикское ― (451 ± 43) мБк·кг-1 239+240Pu. Наименьшие уровни зафиксированы в озёрах континентального происхождения из Перекопской группы: оз. Киятское ― (24 ± 6), оз. Кирлеутское ― (48 ± 4), оз. Красное ― (95 ± 9) мБк·кг-1 239+240Pu. Сравнительный анализ концентрации активности 239+240Pu в поверхностном слое донных отложений показал, что в осадках прибрежных черноморских акваторий уровни 239+240Pu в среднем в 2 раза выше, чем в исследованных солёных озёрах западной части Крыма. Оценены дозовые нагрузки в илах поверхностного слоя соленых озёр. Показано, что мощности эквивалентных доз не превышали диапазон мощностей доз от природного радиационного фона.

Geo-additive Models in Small Area Estimation of Poverty
Authors: Pusponegoro Novi Hidayat , Djuraidah Anik , Fitrianto Anwar , Sumertajaya I Made
Published: July 2019

Spatial data contains of observation and region information, it can describe spatial patterns such as disease distribution, reproductive outcome and poverty. The main flaw in direct estimation especially in poverty research is the sample adequacy fulfilment otherwise it will produce large estimate parameter variant. The Small Area Estimation (SAE) developed to handle that flaw. Since, the small area estimation techniques require “borrow strength” across the neighbor areas thus SAE was developed by integrating spatial information into the model, named as Spatial SAE. SAE and spatial SAE model require the fulfilment of covariate linearity assumption as well as the normality of the response distribution that is sometimes violated, and the geo-additive model offers to handle that violation using the smoothing function. Therefore, the purpose of this paper is to compare the SAE, Spatial SAE and Geo-additive model in order to estimate at sub-district level mean of per capita income of each area using the poverty survey data in Bangka Belitung province at 2017 by Polytechnic of Statistics STIS. The findings of the paper are the Geo-additive is the best fit model based on AIC, and spatial information don't influence the estimation in SAE and spatial SAE model since they have the similar estimation performance.

Authors: Da Silva Silvio Bitencourt , Bitencourt Claudia Cristina
Published: July 2019

Neste artigo tem-se por objetivo investigar como são orquestradas redes de inovação constituídas com o conceito de living lab, para o desenvolvimento de inovações sociais. Pesquisa pautada na abordagem qualitativa, caracterizada como estudo de caso, tendo como base a coleta de dados a partir de 11 entrevistas semiestruturadas com os responsáveis por dois living labs brasileiros já vinculados a European Network of Living Labs (ENoLL).  As interpretações dos textos foram realizadas por meio da técnica de análise de conteúdo e da técnica de adequação ao padrão a partir do conjunto de processos e ações específicas, denominado de “orquestração de redes de inovação”. O estudo promove a conexão da noção de “orquestração de recursos” preconizada na Visão Baseada em Recursos (VBR) com os processos de “orquestração de redes de inovação”. As evidências obtidas demonstram que a adição do processo de gestão da co-criação ao conjunto, reforçado através de algumas ações específicas (empoderamento, engajamento social e conexão social) permite a orquestração de redes de inovação para o desenvolvimento de inovações sociais constituídas em torno do conceito de living lab.
Abordagem sobre a participação no Governo Lula
Authors: PALUDO JOSÉ ROBERTO
Published: July 2019

O tema da participação em políticas públicas ganhou espaço na agenda institucional nos anos 1980, despertou grande interesse na academia e embora se perceba um declínio da sua ação o Brasil ainda é considerado um “laboratório de experiências” de práticas participativas para o mundo (CORTES e SILVA, 2010).O presente artigo inicia por uma revisão das principais correntes teóricas que abordam o tema da participação em políticas públicas e em seguida apresenta os resultados da experiência desse tipo de política na esfera federal, durante o governo Lula (2003/10) a partir de um balanço publicado pela Secretaria Geral da Presidência da República (SGPR - BRASIL, 2011) e do Comunicado de número 132 do IPEA (2012).Tais documentos são analisados à luz do referencial teórico e apontados avanços e desafios futuros.
