Service Investment and Channel Structure Decisions in Competing Supply Chains
Authors: Xia Yusen , Xiao Tiaojun , Zhang G. Peter
Published: March 2019

Supply chain versus supply chain is an important aspect of business competition as the channel structure of each supply chain affects its own channel profit as well as the rival’s channel profit. Manufacturers have two distribution channel structure strategies: integrated channel and decentralized channel. The channel structure strategy can be influenced by price and service, two key competitive dimensions that affect both customer demand and firm profitability. The authors develop game-theoretic models to explore channel structure strategies for two manufacturers competing on price and service and examine how service provisions affect these strategies. Here, service can be provided by either producers (i.e., manufacturers) or sellers. When manufacturers provide service, this study reveals that symmetric decentralization (i.e., both manufacturers choosing a decentralized channel) is an equilibrium only when price elasticity, service cost, and service competition are low. When service is provided by sellers, symmetric decentralization is an equilibrium only when the retailer’s service cost is high and that of the manufacturer is low; otherwise, an asymmetric equilibrium may exist.

ResumoA atuação adequada dos Conselhos de Alimentação Escolar gera perspectivas de redução de irregularidades na utilização dos recursos públicos e melhoria da qualidade da alimentação escolar. Buscou-se, neste estudo, conhecer as condições de trabalho e atuação dos conselheiros segundo as normativas do Programa Nacional de Alimentação Escolar. Foi realizado estudo transversal com 425 conselheiros oriundos de 84 municípios de Minas Gerais e Espírito Santo. Foram realizadas análises descritivas, univariadas e multivariadas, utilizando testes do qui-quadrado de Pearson e regressão de Poisson, obtendo-se a razão de prevalência. Os resultados do estudo indicaram funcionamento precário dos conselhos, assim como condições de trabalho inadequadas para os conselheiros, que têm sua atuação prejudicada pela inadequação de infraestrutura de trabalho. As razões de prevalência sugerem uma ação positiva no controle social quando o conselheiro é eleito democraticamente, quando possui adequada infraestrutura de trabalho e acesso a informações sobre o programa. Os achados denotam a necessidade de propiciar aos conselheiros educação continuada, melhorar suas condições de trabalho e favorecer sua atuação participativa e democrática, propiciando um efetivo controle social do programa.DOI: 10.12957/demetra.2019.37875

Authors: de Azevedo José Moreira , Gaspar Carolina , Andresen Carolina , Barroso Maria , Costa Horácio
Published: March 2019

Pilonidal disease occurs in 26 in 100 000 people, affecting mainly men aged 20–30 years. It is treated by a variety of surgical techniques; however, there is a lack of consensus on the optimal choice of treatment for complex pilonidal disease. In addition, there is no consensus regarding care of the wound after surgery. Negative pressure wound therapy applied to open wounds following pilonidal disease surgery has been suggested as a way to decrease healing times and costs and is an emerging option for complex and or recurrent pilonidal disease. This study describes a case of complex pilonidal disease managed with local excision and negative pressure wound therapy followed by a split-thickness skin graft.
A nursing metaparadigm perspective of diabetic foot ulcer care
Authors: Subrata Sumarno Adi , Phuphaibul Rutja
Published: March 2019

Diabetic foot ulcers (DFUs) are a serious complication of diabetes that impact on the patient, their social environment, overall health, and on nursing practice. Nursing scholars have integrated theories on practice to overcome these problems, but a lack of agreement in the available literature acts as a barrier to implementing these in practice. For that reason, using a nursing metaparadigm as a theoretical framework would assist nurses in managing care purposefully and proactively, thus possibly improving outcomes. There has been little discussion about the nursing metaparadigm in relation to DFU care. This article aims to identify why Fawcett's theory of the nursing metaparadigm is important as a fundamental part of DFU care. Understanding this will help to elucidate the phenomenon of DFUs. Moreover, identifying the elements of the DFU care framework is essential to improve reflective practice and intervention. This article discusses the concept of the nursing metaparadigm and its implications for practice in the care of patients with DFUs.

Published: March 2019

Although managing the consequences of tooth loss is not easy, the desired outcome can be achieved with collaboration by the patient, clinician and technician. The ultimate objective is not to reverse the effects of ageing but to improve the quality of life of an affected individual by adhering to biological procedures as much as possible and replacing missing teeth in the most appropriate way.

CPD/Clinical Relevance: This case report describes the management of localized anterior tooth wear in a patient with bilateral distal extension edentulous mandibular arches.
‘They were extraordinary circumstances’: Biopolitics, medicine and the state of exception in NBC’s The West Wing
Authors: Kasper Daniel
Published: March 2019

In the final moments of NBC’s series The West Wing (1999–2006), the camera briefly shows a copy of Michel Foucault’s Society Must Be Defended ([1992] 2003) sitting on a bookshelf in the fictionalized Oval Office. Coming as it does at the end of the series, Foucault’s work becomes an interlocutor of the issues, political and personal, that the show explores. Given that Foucault’s work is his first to take up biopolitics in his lectures at the College de France, its inclusion gives viewers an opportunity to explore how The West Wing grapples with the open questions of sovereignty and biopolitics in the neo-liberal, post-9/11 present of the series and of the historical moment. This article addresses these questions with a combination of Foucault’s work and Giorgio Agamben’s concept of the ‘state of exception’. By focusing mainly on two episodes – ‘17 People’ and ‘Dead Irish Writers’ – as well as the antecedent and subsequent narrative threads, the conflicts between the ancient regime of the king’s two bodies and the modern technology of biopower become clear. The biopolitical healthcare of the president’s body, I argue, complicates the clarity of the sovereign power of the president, allowing other political actors – the first lady especially – access to the state of exception. Ultimately, though the show does not offer us a pathway to liberation, it begins the arduous process of escaping from the king’s two bodies.
I’m (not) a girl: Animating experiences of girlhood in Bob’s Burgers
Authors: Barnett Katie
Published: March 2019

Discourses of girlhood increasingly acknowledge its mutability, with the ‘girl’ as a complex image that cannot adequately be conceptualized by age or biology alone. Likewise, theories of animation often foreground its disruptive potential. Taking an interdisciplinary approach that encompasses girlhood studies, animation studies and screen studies, this article analyses the representation of the two main girl characters, Tina and Louise Belcher, in the animated sitcom Bob’s Burgers (2011–present). Taking this concept of mutability as its central focus, it argues that animation is an ideal medium for representing girlhood, given its disruptive potential and non-linear capacities, whereby characters are often frozen in time. With no commitment to ageing its young female characters, Bob’s Burgers is instead able to construct a landscape of girlhood that allows for endless reversal, contradiction and overlap in the experiences of Tina and Louise, whose existence as animations reveals girlhood as a liminal space in which girls can be one thing and the other – gullible and intelligent, vulnerable and strong, sexual and innocent – without negating their multifarious experiences.
Looking through the upside down: Hyper-postmodernism and trans-mediality in the Duffer Brothers’ Stranger Things
Authors: Mollet Tracey
Published: March 2019

This article puts forward the argument that Stranger Things (2016–present) is not only an excellent example of postmodern TV drama, but it takes on what Valerie Wee has termed a ‘hyper-postmodernism’ through its heightened level of intertextual referencing that emerges ‘as text’. Both seasons of the show (thus far to date at the time of writing) also extensively break down the boundaries between film, television, literature and ‘geek’ culture. This is done within the text itself, and through the audience’s invited interaction with the text, as the show demonstrates significant awareness of the trans-medial, Easter-egg hunting tendencies of its binge-watching followers.
Grandes incêndios florestais de março, junho e outubro (fora do período crítico) em Portugal continental
Authors: Fernandes Sofia , Lourenço Luciano
Published: March 2019

Em Portugal Continental, os grandes incêndios florestais não se limitam aos meses de julho, agosto e setembro, quando são mais frequentes, uma vez que também ocorreram imediatamente antes e após esses meses, ou seja, respetivamente em junho e outubro, e, ainda, no mês de março, como o demonstram os mais recentes grandes incêndios registados fora do período crítico, designadamente nos anos de 2011, 2012 e, muito em particular, de 2017. O presente estudo visa averiguar a incidência regional deste tipo de ocorrência no território português, bem como a sua evolução após o ano de 1980 e, ainda, verificar o contributo das condições meteorológicas para estas situações, através da análise da existência de eventuais similitudes nas condições meteorológicas verificadas nos anos mais críticos. Os resultados obtidos mostram que, desde da última década, se verificou um agravamento do risco de incêndio florestal fora do período crítico em Portugal Continental, nomeadamente na região Centro e com particular relevância nos distritos da Guarda e de Coimbra. Este agravamento do risco é, em parte, o reflexo da intensificação de certas condições meteorológicas que se têm vindo a registar desde o início deste século. Por isso, é fulcral que o dispositivo de combate seja ajustado às condições meteorológicas, ou seja, quando se prevê que elas sejam favoráveis à deflagração e à propagação de incêndios florestais no território.
As vagas de incêndios florestais de 2017 em Portugal continental, premissas de uma quarta ‘geração’?
Authors: Félix Fernando , Lourenço Luciano
Published: March 2019

A evolução dos incêndios em Portugal continental, ao longo dos últimos cinquenta anos, não tem sido constante, o que permite, combinando diferentes parâmetros estatísticos, estabelecer diferentes “gerações” de incêndios. Do cruzamento dos elementos analisados resultaram quatro gerações de incêndios. O fator mais importante para a definição dessas gerações foi, sem dúvida, o da área do maior incêndio registado em cada ano. Considerou-se um intervalo de 10 mil hectares, para separar as diferentes gerações de incêndios, e obtiveram-se quatro gerações. Na última classe teve de ser usado o dobro desse valor, dadas as circunstâncias anormais registadas em 2017, ano que marcou o início da quarta geração de incêndios de Portugal.
Antibiotic resistance of Staphylococcus aureus isolates from milk produced by smallholder dairy farmers in Mbeya Region, Tanzania
Authors: Massawe H. F. , Mdegela R. H. , Kurwijila L. R.
Published: March 2019

Aim: The study determined and evaluated the prevalence and antibiotic resistance of Staphylococcus aureus isolated from milk collected along the milk value chain from farm herds, milk collection center, and milk shops in Mbeya rural and Mbozi districts, Tanzania.

Materials and Methods: A total of 150 milk samples were collected; 96 from farmers' herds, 18 from milk collection centers, and 36 from milk shops. The samples were cultured in Mannitol salt agar for pathogen isolation and biochemical tests performed for confirmation of S. aureus. Kirby-Bauer disk diffusion method was employed for antibiotic resistance testing.

Results: One hundred and forty samples yielded Staphylococcus species; these were from farmer's herd (92), milk collection center (18), and milk shops (30), respectively. Biochemical tests showed that 21 (15%) were positive for S. aureus. The corresponding prevalence rates from the value chain nodes were 14.1%, 16.7%, and 16.7%, respectively. Resistance to penicillin was frequently observed (57.1%) and vancomycin was sensitive to all S. aureus isolates tested. Resistance along the sampling points showed a significant positive correlation (r=0.82, p<0.0001; r=0.65, p<0.003; and r=0.61, p<0.01) between farmers, milk collection points, and milk shops, respectively. More than half (57.1%) of the isolates exhibited resistance to three or more of the antibiotics used in this study. S. aureus isolates were shown to have a multiple antimicrobial resistance patterns, particularly with respect to penicillin, ampicillin, erythromycin, and tetracycline.

Conclusion: The level of staphylococcal isolates and the antibiotic resistance of S. aureus found in this study is an indication of subclinical mastitis, poor hygiene, and inappropriate use of antibiotics; therefore, education of farmers on subclinical mastitis control and proper use of antibiotics would be of benefits in these areas.
GC-MS Profile of Volatile Oils Extracted from Jatropha multifida L. using Hydrodistillation and Solvent-Free Microwave Extraction Methods
Authors: Wintola O.A. , Ajayi E.O. , Afolayan A.J.
Published: March 2019

Volatile oils were extracted from the leaves of Jatropha multifida using solvent free microwave and hydrodistillation methods and the oils obtained were analyzed by gas chromatography-mass spectrometry (GC-MS). The major compound as observed is eucalyptol with 70.38 and 35.62 % for solvent-free microwave extraction (SME) and hydrodistillation extraction (HDE), respectively. The oil compositions were dominated by oxygenated compounds. Oxygenated monoterpenes were prevalent in contrast to monoterpenes hydrocarbons. The oils were also characterized by oxygenated sesquiterpenes (SME, 6.05 %; HDE, 7.34 %). This study may provide information on a suitable method of extraction of the essential oil for industrial application and may assist in the realization of the essential oil as a natural source of plant and animal food additives. These various bioactive compounds in the essential oil may partially justify their use in folklore medicine.

Published: March 2019

Adjustably biodegradable materials have gained much attention in biomedical applications. Among of them, various hydrogel-based scaffolds have applied for regenerating soft and hard tissues. In this study, according to differently biological properties of gelatin or chitosan as well as biphasic calcium phosphate nanoparticles (BCPNPs), several injectable nanocomposite hydrogels (INgel) were enzymatically fabricated from a phenolic chitosan derivative (PCD), phenolic gelatin derivative (PGD) and BCPNPs. According the change of H2O2 concentration with follow-up the time, the in situ formation of INgel was varied from 35 to 80 s. The degradation rate of the nanocomposite materials significantly related to in presence of collagenase that expended from 3 days to over one month depending on amount of the formulated PCD. The BCPNPs-encapsulated PCD-PGD INgel enhanced mineralization in the simulated biofluid. Fluorescent cytotoxicity assay indicated that the INgel was fabricated from a higher amount of the PGD resulting in a significant proliferation of bone marrow mesenchymal stem cells. These preliminary results exhibited a great potential of the INgel for bone regeneration.

Da Lei Maria da Penha para a sala de aula: violências contra as mulheres e o ensino de Sociologia
Authors: Campos Mariana De Lima
Published: March 2019

Propõe-se uma discussão acerca da relevância da inserção da temática “violências contra as mulheres” nas escolas, evidenciando o papel da disciplina Sociologia. A partir dos princípios epistemológicos de estranhamento e desnaturalização, que possibilitam a transformação de questões sociais em objetos de reflexão, entende-se a temática como um recurso possível para o aprendizado da Sociologia na educação básica. Sob a ótica do processo de implementação da Lei Maria da Penha, evidencia-se como o debate pode subsidiar processos de enfrentamento das violências num âmbito preventivo, por meio da desconstrução das assimetrias de gênero que perpetuam socialmente hierarquias de poder entre homens e mulheres - base e causa das violências, e empecilho à busca da equidade de gênero.

PROCESSOS EDUCATIVOS COM FOCO NOS BRINCARES, NAS SEXUALIDADES E NAS RELAÇÕES DE GÊNERO EM UMA BRINQUEDOTECA NO SUL DE MINAS GERAIS
Authors: Martins Kátia Batista , Ribeiro Cláudia Maria
Published: March 2019

Este estudo é um recorte da pesquisa de mestrado, que investigou os processos educativos desencadeados numa brinquedoteca, com foco nas relações de gênero e sexualidades imbricadas nos brincares. Pautada na pesquisa qualitativa em educação e na análise da empiria, construiu-se as ferramentas investigativas ancoradas nos estudos pós-estruturalistas. Investigou-se a realidade de uma brinquedoteca no sul de Minas Gerais, que atende crianças de 2 à 7 anos. O recorte analisa os questionários respondidos pelas educadoras sobre os temas em pauta. Concebemos a construção de gênero, como enfatiza Scott, e o discurso sobre a sexualidade, cunhado por Foucault, social, histórica e culturalmente. São questões sociais e políticas que devem ser discutidas nos espaços educativos, imbricadas nos brincares como espaço de diálogo e de novas possibilidades de ser e de estar no mundo. Verificamos como os processos educativos analisados, adotam práticas advindas de um currículo conservador, numa perspectiva que carrega marcas de controle e disciplinamento dos corpos.

Inhibition of Aromatic Amino Acid Decarboxylase by a Group of New Potential Nonsteroidal Anti-Inflammatory Drugs with Antileukotrienic Effects
Authors: Dršata Jaroslav , Kuchař Miroslav
Published: March 2019

Possible in vitro inhibition of aromatic amino acid decarboxylase (AAD, EC 4.1.1.28) by a group of phenylsulfonylbenzoic acid derivatives VÚFB 19363, 19369, 19370, 19371, and 19760 as new potential anti-inflammatory compounds was studied using the substrate L-tyrosine. Enzyme inhibition by 2.7x10–5 M concentration of compound VÚFB 19363 (Quinlukast) was 17 %, AAD inhibition at 3.75 x 10–5 M concentration of compounds VÚFB 19369, 19370, 19371, and 19760 ranged between 9–23 %. There were distinct differences between individual compounds. Evaluation of inhibition kinetics suggested full reversibility with VÚFB 19369 and the uncompetitive type of inhibition in the case of compound VÚFB 19363. Considering the anti-inflammatory activity of the compounds studied, the weak AAD inhibition found is rather favourable for their prospective pharmacological effect.

Each time the channels can only accommodate a limited number of systems for communication and the successful packet arrival rate at the controller depends on the power used by the sensor. Then in order to satisfy the medium access constraint, reduce the communication energy cost and stabilize the collection of NCSs, one needs to decide when to schedule which plant to communicate by which channel and by which power level. Based on the average dwell time technique, sufficient conditions for the exponential mean square stability of a single plant are given at first. Then, based on the stability conditions, a period scheduling policy is proposed to assign the channel accessing sequence and power level such that all the plants are simultaneously stabilized. Finally, a new framework for channel assignment, power allocation and controller design is constructed, which can guarantee a desired decay rate for each system and a minimal energy consumption for the group of systems. The effectiveness of the methodology is demonstrated with numerical simulations.

Flexibel einsetzbare Fertigungssysteme müssen sich bei individuellen Fertigungsaufgaben im Kontext von Losgröße 1 automatisch in ihrem Bewegungsverhalten auf unterschiedliche Werkstücke anpassen. Hierzu benötigen sie fortschrittliche Steuerungen, die oft auf einer Optimierung basieren. Eine Offline-Optimierung reicht aufgrund der dynamischen Folge an unterschiedlichen Werkstücken nicht aus. Die große Herausforderung liegt nun darin, eine echtzeitfähige selbstoptimierende Steuerstrategie für eine Industriesteuerung zu entwerfen und zu implementieren, welche die Optimierung online ausführt.

Im vorliegenden Beitrag wird anhand der Trajektorienplanung eines anwendungsbezogen redundanten sechsachsigen Hybridmechanismus eine solche modellprädiktive Steuerstrategie vorgestellt, die auf einer speicherprogrammierbaren Steuerung (SPS) ausgeführt wird und die Verfahrzeiten des Mechanismus zwischen werkstückspezifischen diskreten Bearbeitungspositionen optimiert. Es werden die Gütefunktion sowie die eingesetzten Modelle vorgestellt. Zudem erfolgt eine Analyse hinsichtlich der für die Berechnung erforderlichen Zykluszeit, der erzielten Ergebnisse und des Einflusses von Optimierungsparametern.

Introduction

Physical activity (PA) is proven to be an effective strategy to avert the life threatening cardiovascular diseases. There is need for developing feasible aids to improve compliance to PA. Hence, we conducted a study among medical college students a) to assess the prevalence of recommended PA level and b) to assess the effectiveness of installing a smartphone application (app) in improving PA.

Methodology

A quasi-experimental study was conducted among medical college students in Puducherry, India. The baseline PA was assessed using the Global Physical Activity Questionnaire (GPAQ) and anthropometric measurements such as height and weight were measured as per World Health Organization (WHO) standards. A smartphone app (Runtastic) was installed on the mobile phones of all study participants. At the end of 1 month, the end line PA and anthropometric measurements were captured using same scales.

Results

Of the total 350 students who were included, the mean age of the participants was 18.9 (0.9) years and 58% of them were male. The proportion of participants with the WHO recommended level of PA increased from 81% at the baseline to 91% after 1 month of installation of the mobile app (p < 0.001). There was also a statistically significant increase in the leisure time PA [median (interquartile range – IQR) of metabolic equivalents (METS): 0 (0–1600) vs. 1260.0 (0–1920)]. Clinically significant change was not seen in body mass index (BMI) though the reduction was statistically significant [(mean (standard deviation – SD) of BMI: 22.54 (2.49) vs. after intervention 22.46 (2.47); p = 0.018].

Conclusion

This quasi-experimental study conducted among medical college students reported significant improvement in total and leisure time PA.

To investigate the deformation property of weathered phyllite filling subgrade under the comprehensive effect of water and load, three weathered phyllite soil column models were filled and their deformations were tested through a laboratory test and numerical simulation in this article. The results show that the deformation of the weathered phyllite soil column models were greatly influenced by the water replenishment conditions and load conditions, and the deformation of models increased with the increase of the moisture content and load. Moreover, the larger the load, the longer the time required for the weathered phyllite soil column model to reach stability. In addition, the numerical simulation results were compared with the test results, and it was found that they were similar. Consequently, the numerical simulation can be used to reflect the deformation of weathered phyllite filling subgrade under the effect of water and load and provide some guidance for the design of the weathered phyllite filling subgrade.

Este trabalho consiste em avaliar as alterações na paisagem sob os diferentes sistemas de cultivo do tabaco, Sistema de Plantio em Cultivo Mínimo (SPCM), e Sistema de Plantio Convencional (SPC), em uma área localizada na bacia do rio Cachoeira, Rebouças - PR, com ênfase nas dinâmicas e fases de cultivo, manejo e exposição do solo. Quanto à problemática trata-se de uma pesquisa qualitativa, vista que envolve a avaliação de diferentes paisagens, através de uma proposta de análise descritiva, abordando diretamente a paisagem nas diferentes formas de cultivo. Para a consecução da proposta foi realizado pesquisa de campo com avaliação dos componentes da paisagem, durante três fases do calendário agrícola. Os resultados mostram que as diferentes formas de manejo vinculadas a ação antrópica exercida durante o ciclo de cultivo, propiciam na paisagem alterações e posições únicas mediante a cada fase analisada. Desta maneira conclui-se que as dinâmicas de cultivo do tabaco, atribuída às características morfopedológicas, fisicas, econômicas e antrópicas, definem e determinam as relações com o espaço geográfico, atribuindo a paisagem funções e estruturas diferenciadas devido às características produtivas deste tipo de cultivo.ABSTRACTThis work consists of evaluating the changes in the landscape under the different tobacco cultivation systems, Minimum Planting System (SPCM), and Conventional Planting System (SPC), in the area located in the waterfall river basin, Rbouças- PR, with emphasis on the dynamics and phases of cultivation, management and soil exposure.
