Authors: Bohner Lauren , Hanisch Marcel , De Luca Canto Graziela , Mukai Eduardo , Sesma Newton , Neto Pedro Tortamano
Published: November 2018

The purpose of this study was to compare the accuracy of stereolithographic casts (SCs) with those obtained using conventional implant impressions. An epoxy resin model containing dental implants was used as master model. Dental casts (n = 10) were fabricated through both conventional and digital implant impressions. The conventional casts (CCs), SCs, and the master model were digitized, and the accuracy was determined through a deviation analysis and linear measurements. Data were analyzed using paired Student t test with P < .05. The SCs showed higher deviation at the vestibular area (CC: 41 ± 28.87 μm; SC: 117 ± 36.83 μm) and lingual cusps (CC: 40.70 ± 19.79 μm; SC: 80 ± 42.95 μm) in comparison with CCs. No statistically significant difference was found for linear measurements of conventional and digital casts. The entire-arch accuracy was comparable between casts. However, SCs were less accurate at the cusp level in comparison with CCs.

Authors: Lee Jong-Bin , Kweon Helen Hye-In , Cho Hyun-Jae , Kim Chang-Sung , Kim Young-Taek
Published: November 2018

Local delivery agents (LDAs) are widely used in peri-implantitis treatments. The aim of this study was to identify LDAs remaining on the dental implant surfaces and to analyze the components of these residues after applying various cleaning methods. Implants were prepared with a sand-blasted, large-grit, acid-etched surface. Four kinds of LDAs were applied on the implant surfaces: chlorhexidine gel (group 2), tetracycline solution (group 3), and 2 kinds of minocycline hydrochloride agents (groups 4 and 5). Group 1 received normal saline as a control. Two cleaning methods were applied for different durations as follows: (1) running distilled water for 10 seconds (subgroup A), 5 minutes (subgroup B), and 15 minutes (subgroup C); and (2) water spray of a dental-unit chair for 10 seconds (subgroup D) and 5 minutes (subgroup E). Scanning electron microscopy and energy-dispersive x-ray spectroscopy were used to analyze the surface morphology and residue components for all implants. The amount of LDA removed from the implant surfaces in groups 1, 2, 3, and 5 increased with the cleaning duration and pressure. However, Minocline remained coated on the implant surfaces in group 4 under all cleaning conditions. Minocline could not be cleaned off well by water due to its hydrophobicity. Therefore, directly using this agent on implant surfaces with peri-implantitis should be carefully considered. The presence of LDA residues without drug efficacies on implant surfaces might interfere with reosseointegration and act as a reservoir of microorganisms.
Maputo: Ethnography of a Divided City
Authors: Tvedten Inge , Ribeiro Fábio , Graça João , Bertelsen Bjørn Enge
Published: November 2018

Rapid urbanisation is one of the most dramatic developments on the African continent, often yielding contrasting and shocking images of affluent businesses and residential districts alongside sprawling shantytowns or slums. Urban areas account for an increasing part of the continent’s positive macro-economic development and represent opportunities for employment, education, health, leisure and well-being. However, urban growth is also manifested in emerging conditions of inequality and poverty, rising environmental problems, situations of political instability and riots, as well as persistent high levels of urban crime and violence.

This film project seeks to visualise Maputo: one of Africa’s divided cities. It is part of the research project “The Ethnography of a Divided City. Socio-Politics, Poverty and Gender in Maputo, Mozambique” headed by the Chr. Michelsen Institute and funded by the Norwegian Research Council. While the film relates actively to the research project, it approaches the project’s themes from new and original angles and ANIMA has had full artistic freedom in its filmic approach. A focus on the people inhabiting the city’s so-called bairros (districts/areas) provides a privileged view of the way in which symbolic and material boundaries of various urban spaces are contested, negotiated and, ultimately, inscribed onto mental maps of the city.

Archiving Plaques: saving virus purification for later v1
Authors: Kauffman Kathryn , Polz Martin
Published: November 2018

In plaque-assay based viral discovery many more plaques are often generated than can be examined at any one time, it is therefore of value to be able to archive plaques for future investigation. To address the potential for differences among viruses in tolerance to storage, this protocol provides large-scale archival approaches that include storage of picked plaques at both 4°C and -20°C or -80°C. We note however, that viruses differ in their sensitivity to storage conditions (Clark 1962 [1]; Fortier and Moineau 2009 [2]) and, though we describe methods that include multiple conditions, we highlight also that including additional approaches, such as storage in infected cells (Golec et al. 2011 [3]), is likely to increase total proportion of recovered viruses in large collections.

Tube-free Agar Overlays: rapid plaque assays with fewer steps and materials v1
Authors: Kauffman Kathryn , Polz Martin
Published: November 2018

This protocol simplifies current approaches for agar overlay plaque assays by eliminating the use of tubes for premixing of agar, hosts, and viruses, in favor of pipetting each of these directly onto the bottom agar. The benefits of this approach include simplified experimental set-up, and reductions in preparation and clean-up times and material requirements. In addition, by eliminating tube-based steps, the duration of exposure of cells and viruses to heat is reduced and the need for potentially damaging vortexing or agitationof virus-host mixtures is also eliminated. We note that Hershey et al. [1] mentioned the possibility of such an approach in their 1943 description of the tube-based overlay procedure, stating: “A further slight improvement may be made by mixing the sample directly on the phage with only 3ml 0.7 per cent agar, but the mixing is difficult.” By using a lower percentage agar, which is advantageous for other reasons (see Additional Information section in the associated publication), we find that this approach works very well with as low as 2ml of top agar. Using this streamlined, tube-free, plating method, >45 samples can readily be plated per hour from a common or pre-prepared virus stock, without the need for individual tubes of molten agar or multiple transfers of bacteria and virus. When deployed for isolation of novel viruses, or quantification of environmental viruses, this translates to a potential for screening hundreds of potential host strains per day using a single bottle of molten agar rather than hundreds of tubes. When used for routine bench assays, a single bottle of top agar can be used over multiple days by simply re-microwaving. [1] A. Hershey, G. Kalmanson, J.

Molten Streaking for Singles: rapid tube-free serial purification of viruses v1
Authors: Kauffman Kathryn , Polz Martin
Published: November 2018

This protocol presents a simplified approach for purification of viral strains directly from plaques without the need for preparation of dilutions. Using the 'Tube-free agar overlay' approach viruses are 'picked' directly from source plaques with a toothpick and streaked into molten host lawns in a manner directly analogous to re-streaking based colony purification of bacteria. This approach requires less time and material than dilution based approaches and yields equivalent purification of viruses.Formation of plaques along streaks also offers further confidence that plaques selected for further purification derive from an isolated phage particle rather than a splash containing multiple viruses or a prophage induction event. A video demonstrating the approach is available as supplementary material with the original publication (direct link here).
Pharmacoeconomic analysis of using belimumab for the treatment of systemic lupus erythematosus
Authors: Tolkushin A. G. , Pogudina N. L.
Published: November 2018

The aim is to study the clinical and economic aspects of using belimumab for the treatment of systemic lupus erythematosus (SLe) in patients with high SLe activity, the presence of anti-DNA, a low level of complement in the blood plasma and minimal lupus organ damage at the early stage.

Materials and methods. The Markov model of SLe is used. The initial probabilities of the Markov transitions are obtained from analysis of published clinical and observational studies. The prices of the relevant drugs were obtained from the VeD price registry. Medical and nonmedical expenses are calculated on the basis of the current standards for financial costs and coefficients, as well as payments for temporary and permanent disability. Indirect costs are calculated using the method of human capital.

Results. It has been found that using belimumab leads to a decrease in costs (both direct and indirect), as well as an increase in patient survival. The total costs for belimumab vs standard therapy approximated 8.84 million rubles vs 17.72 million rubles (of which 4.05 million rubles vs 5.58 million rubles were direct costs, and 2.57 million rubles vs 2.88 million rubles were indirect medical costs) on average per patient in the belimumab group vs standard therapy group, respectively.

Conclusion. The use of belimumab in the target population of patients is pharmacoeconomically justified and expedient because it leads to increased treatment efficiency and reduction of direct and indirect costs.

Authors: Lawson Victoria ,   Dartmouth Hitchcock Clinic, Geisel School of Medicine at Dartmouth, Lebanon, NH, US, Robbins Nathaniel M ,   Dartmouth Hitchcock Clinic, Geisel School of Medicine at Dartmouth, Lebanon, NH, US
Published: November 2018

Multifocal motor neuropathy (MMN) is a rare neuropathy that is often treatable with immunomodulatory therapy if diagnosed early. However, accurate diagnosis is difficult due to a significant overlap of symptoms with other neurological conditions, such as amyotrophic lateral sclerosis (ALS). Evidence of immunoglobulin M (IgM) anti-ganglioside GM1 antibodies and electrodiagnostic findings of conduction block are useful diagnostic criteria for MMN but are not universal findings. This review explores the differential diagnosis of MMN and ALS and discusses three cases of MMN initially diagnosed as ALS, in which the correct diagnosis allowed effective treatment. These cases highlight the need for greater awareness of MMN among physicians.

Falls are increasingly recognized as a threat to the safety, health and well-being of people with multiple sclerosis (MS), and emerging evidence suggests that full time wheelchair and scooter users with MS have unique fall prevention needs. This review is comprised of three parts. Part 1 summarizes findings describing influences on falls among full time wheelchair and scooter users with MS and associated clinical implications. Although further studies are needed, early findings regarding influences on fall risk operating in this specific population highlight the importance of addressing falls that occur during activities of daily living, the high frequency of falls occurring in the bathroom, and both extrinsic (e.g., wet/slippery surfaces) and intrinsic (e.g., muscle spasticity/weakness) contributors to falls. Part 2 of this review describes available evidence regarding interventions to prevent falls in full time wheelchair and scooter users with MS. Because intervention work in this area is limited to one pilot study, Part 3 presents priorities for future research and identifies the need for randomized trials evaluating fall prevention programs that address diverse fall risk factors and allow for development and attainment of individualized fall prevention goals.

Duchenne muscular dystrophy (DMD) is a rare, inherited neuromuscular disorder.Methods:To describe the clinical characteristics and healthcare resource utilization (HCRU) of male patients with DMD in commercial and Medicaid cohorts, this retrospective study identified male patients in the Truven Health MarketScan® Commercial and Medicaid databases diagnosed with hereditary progressive muscular dystrophy (HPMD) presumed to have DMD between 2011–2014. Patients with ≥2 medical claims with a diagnosis for HPMD (International Classification of Diseases, 9th revision, ClinicalModification:359.1) were included. Patients were followed for 12 months after diagnosis date, during which clinical characteristics and HCRU were assessed.Results:In total, 2,285 patients met the selection criteria. In these patients, corticosteroid and anti-infective agents were commonly utilized. Physician office visits were extremely common, with over 70% of all patients having at least one visit. Wheelchairs were commonly used, with the incidence of use increasing with age. Mechanical ventilators and airway clearance devices were underrepresented in the data.Conclusion:Patients with DMD had higher annual HCRU costs when compared with a non-DMD age-matched cohort, with patients in commercial cohorts having a higher annual average cost than those in Medicaid cohorts.

Autosomal-dominant transthyretin (TTR)-related amyloidosis usually manifests in the third to fifth decade with a length-dependent axonal neuropathy and prominent involvement of the small diameter nerve fibers.Objectives:To describe the clinical and para-clinical findings in patients with hereditary transthyretin amyloidosis (hATTR), formerly known as transthyretin-related familial amyloid polyneuropathy (TTR-FAP).Methods:Electrodiagnostic, cerebrospinal fluid (CSF), and TTR gene findings in two patients misdiagnosed with chronic inflammatory demyelinating polyneuropathy (CIDP).Results:A 78-year-old, right-handed, Caucasian male (patient 1) and a 69-year-old, right-handed, Japanese male (patient 2) were referred for late-onset sensory symptoms of the hands and feet as initial manifestations. The first patient, after several years, developed progressive leg weakness affecting his gait and balance, as well as dysautonomic complaints. The second patient had relatively rapid progression with bilateral foot drop and ambulation difficulty after a few months. In both patients, CSF findings were unremarkable. Lumbar spine magnetic resonance imaging did not reveal abnormal thickening or enhancement of the lumbar plexus and exiting nerve roots. Both patients were initially diagnosed with CIDP before being referred to our institution. Patient 2 was started on intravenous immunoglobulin by his primary neurologist, which was maintained for a year without a meaningful response. Repeat electrodiagnostic study at our institution revealed non-length-dependent axonal sensory loss and features of acquired demyelinating neuropathy. TTR gene testing identified pathogenic variants p.Val30Met or V30M, and p.Ala 117Ser or A117S, in the first and the second patient, respectively.Conclusion:hATTR can mimic CIDP clinically and electrodiagnostically. The presence of significant sensory axonal loss, rapid course, and lack of response to immunomodulation therapy should prompt consideration of this diagnosis and TTR gene testing.

Published: November 2018

Purpose: This study evaluated changes in university faculty and staff cardiovascular population risk over a three-year period after the implementation of the Million Hearts®' initiative, which targets the ABCS for cardiac care (i.e., Appropriate aspirin therapy, Blood pressure control, Cholesterol management, and Smoking cessation), with an additional S for Stress reduction.Methods: Using a longitudinal descriptive analysis of population cardiovascular health from 2012 to 2015, the Framingham Risk criteria for over 28,000 continuously-enrolled university faculty and staff were examined in a quality improvement initiative following the implementation of the Million Hearts® national initiative. Launched in 2011 by the Centers for Disease Control and Prevention and the Center for Medicaid Services within the Department of Health and Human Services, the initiative targets modifiable risk factors to prevent one million heart attacks and strokes by 2022.Results: Faculty and staff with low-risk Framingham scores increased from 7.8 % to 14.1 % from 2012 to 2015.Conclusion: Although this study was not a randomized controlled trial, findings support a comprehensive integrated approach to population health and wellness, emphasizing the ABCS of Million Hearts® with an added S for Stress reduction, can improve cardiovascular disease risk.
President's Address 2016: Trafficking in Hope
Authors: Battle V. Duwayne
Published: November 2018

This message is the president's address at the 2016 Annual Conference of the Association of Baccalaureate Social Work Directors (BPD). “Trafficking in Hope” is presented as a personal motif that describes one social worker's approach to social work education and leadership. The author examines his own journey into the field of social work and the person who best modeled for him the compassionate care and consideration of others. Building on the 2016 BPD conference theme, Promoting Excellence in Undergraduate Social Work Through Education and Leadership, social workers are asked to think about who we are at BPD and what makes us so unique. We have the opportunity to raise awareness about who we are, what we do, and the profile of BSW education. Social workers are also challenged to raise our voices and make some noise as we identify with our profession and respond to important social work and social justice issues.

Authors: Jayaseelan Raghul , Sivaprakasam Chidambaranathan , Palanisamy Logesvar
Published: November 2018

Background: Maternal, foetal and placental risk factors have a causative effect in the prematurity and failure to thrive in the early infantile period. Timely diagnosis helps in the anticipation of complications specific to risk factors and managing by impairing their harmful effects on the growth and development of the baby.Methods: The study was conducted prospectively in Department of Paediatrics, Rajah Muthiah Medical College and Hospital, Chidambaram from January 2018 to June 2018. 361 Low birth weight babies were included. Neonates (n=361) weighing less than 2.5 kilograms with parental informed consent are included, whereas those with severe congenital anomaly, systemic disease or infection were excluded from the study. Various known maternal, placental and foetal risk factors are observed during the course of the study. The gestational age of the neonates was estimated using modified Dubowitz scoring. Other factors like mode of delivery of the babies were also noted. Statistical analysis (descriptive statistics) was done by using Microsoft Word 2010.Results: Out of 1040 babies born from January to July 2018, 341 babies weight less than 2.5 kg. Out of which 162 (44.88%) babies were born preterm. Of the full term births 52% were low birth weights The risk factors of the neonates are not mutually exclusive. In the present study 28 maternal risk factors were studied. The prevalence of maternal, fetal and placental risk factors was 85.32%, 74.79% and 6.65% respectively.Conclusions: Period prevalence of low birth weight babies and prematurity is 34.71% and 15.58% respectively. Risk factors are not independent to each other with maternal and foetal risk factors have almost have an effect on nearly three fourths of low birth weight neonates.
FRATURA DIGITAL E POLÍTICAS DIGITAIS EM EDUCAÇÃO: O CASO DA FRANÇA, SENTIDO E “NONSENSE”
Authors: Devauchelle Bruno
Published: November 2018

O sistema escolar francês é particularmente desigual, como a sociedade que o envolve (MAURIN, 2007; 2009). O presente artigo visa mostrar como a preocupação com o tema da desigualdade surgiu e se desenvolveu nos discursos, textos e relatórios oriundos da Educação Nacional Francesa. A partir da análise sistemática do corpus de documentos relativos à informática escolar e à educação digital, nós mostraremos que este propósito é mais revelador de uma crise institucional da escola do que de uma legítima preocupação educativa. Abordaremos enfim, a distância entre o discurso e as realidades observadas.

Published: November 2018

O objetivo principal deste estudo foi analisar as percepções de gestores sobre as práticas de liderança sustentáveis adotadas por empresa agroindustrial. A pesquisa foi qualitativa, tendo como técnica o estudo de caso, realizado por meio de entrevistas e análise de documentos. O caso estudado é de uma Empresa que atua na região Sul do Brasil na produção de suínos, bem como na industrialização de produtos deles derivados. Foi possível constatar, no caso estudado, que os entrevistados entendem que a Empresa elabora estratégias voltadas para a sustentabilidade, cuja dimensão mais percebida é a ambiental. Com relação à liderança, o estudo permitiu captar a valorização dos tipos de liderança: comportamental, transacional e transformacional. Não foi possível capturar preocupação específica de liderança voltada para a disseminação de princípios e valores relativos à sustentabilidade. Este estudo se situa na exploração das interfaces entre liderança e sustentabilidade, fator preconizado pelo Pacto Global da ONU e visa a contribuir para fomentar novos estudos que possam embasar o caminho de gestores e pesquisadores na compreensão de como a liderança pode colaborar para a sustentabilidade em organizações.
Natural resource-based view sob o enfoque social: uma pesquisa bibliográfica
Authors: Silva Luciana Maines da , Stadtlober Cláudia De Salles
Published: November 2018

Essa pesquisa bibliográfica teve por objetivo analisar a produção científica nacional e internacional sobre a aplicação do conceito de Natural resource-based view (NRBV) voltada ao enfoque social (HART, 1995). A NRBV é uma spin-off da Resource-based view (RBV), que trata de recursos e capacidades das organizações para obter e manter vantagem competitiva e desempenho econômico (BARNEY, 2000). O desdobramento dessa teoria propôs, originalmente, três capacidades-chave estratégicas: prevenção da poluição, administração de produtos e desenvolvimento sustentável. Em outro momento, foram percebidas duas novas áreas distintas nas estratégias-chave de desenvolvimento sustentável: tecnologias limpas e base da pirâmide (BoP) (HART; DOWELL, 2011). Verificou-se que a maioria dos artigos utiliza o conceito como base para iniciativas sustentáveis, principalmente ligadas à cadeia de suprimentos. A estratégia-chave de BoP, assim como outro enfoque social, obteve pouco destaque científico, o que demonstra uma lacuna do aspecto social que pode ser melhor explorada.

O milho é um dos cereais de maior importância agrícola de largo consumo, na alimentação animal e humana, por ser altamente energético, apresentar excelente composição e inúmeras aplicabilidades. Objetivou-se neste trabalho determinar a composição centesimal de milho crioulo cultivado em diferentes regiões do estado da Paraíba. As determinações analíticas foram conduzidas no laboratório de Análise Físico-química de Alimentos pertencente à Universidade Federal da Paraíba, Campus - III, Bananeiras, Paraíba. As sementes do milho crioulo Jaboatão, foram provenientes dos agricultores familiares de seis municípios situados entre o brejo e o semiárido paraibano. Após a colheita das sementes, foi realizado em Laboratório a seleção e posteriormente a moagem em moinho de faca tipo Willey das amostras para realização das análises. As análises de proteína, lipídeo, cinzas, umidade e carboidratos foram conduzidas no Laboratório de Físico-química de Alimentos para analisar a composição centesimal do milho crioulo Jaboatão. Foi utilizado o delineamento inteiramente casualizado, com oito tratamentos (seis municípios de coleta) e três repetições. Os resultados obtidos para as análises de proteína e cinzas em milho crioulo Jaboatão apresentaram maiores teores em amostras obtidas do município de Alagoa Nova, onde apresentaram com menor percentual de umidade no material avaliado. Para lipídeos obteve-se maior teor o milho obtido do município de Massaranduba 1, sendo que, as amostras oriundas do município de Remígio 2 tiveram melhor percentual de carboidrato quando comparado com os demais municípios analisados. A variedade de milho crioulo Jaboatão cultivada por agricultores familiares tem potencial nutricional para ser utilizado como fonte de alimentação.

Diversas são as atividades antrópicas que disponibilizam resíduos e rejeitos nos ecossistemas, principalmente os aquáticos, e geralmente de forma inadequada. Como resultado, pode-se haver incrementos da quantidade de nutrientes, principalmente de fósforo e nitrogênio, tornando um meio propício para florações de Cyanobacteria. Objetivou-se com esse estudo identificar a comunidade fitoplanctônica e nutrientes da água em um braço do Rio Grande, Frutal, Minas Gerais, para verificar a possibilidade de uso da água na irrigação de cultivo agroecológico de olerícolas. Nos três pontos amostrais as variáveis temperatura, condutividade, oxigênio dissolvido e pH estavam em conformidade com a CONAMA 357/2005. Os nutrientes (fósforo total, ortofosfato, nitrato, nitrito e nitrogênio amoniacal total) apresentaram baixas concentrações e mantiveram-se em conformidade com a resolução em todos os pontos e períodos analisados. A abundância do fitoplâncton ficou dividida em 3 grandes grupos: Bacillariophyceae, Chlorophyceae e Cyanobacteria. Grandes quantidades de cianobactérias foram observadas nas amostras, trazendo risco devido ao potencial dessas algas para produzir toxinas. Para ser utilizada na irrigação de cultivo agroecológico, é necessário que a água em questão passe por tratamento.

Published: November 2018

The triglycerides to high-density lipoprotein cholesterol ratio (TG/HDL-C) is a useful surrogate marker of insulin resistance and cardiovascular risk factors. We aimed to assess the relationship between the TG/HDL-C ratio and insulin resistance (IR) and its usefulness in prediction of the metabolic syndrome (MS). This retrospective study involved 122 obese children with the mean age of 11.6±3 years and their 58 healthy lean peers. Anthropometric measurements, blood pressure, the plasma lipid profile and oral glucose tolerance test (OGTT) were analyzed. Based on the obtained results, the TG/HDL-C ratio and surrogate insulin resistance indices (HOMA-IR, FGIR, QUICKI, OGIS, Matsuda index) were calculated. The TG/HDL-C ratio positively correlated with weight, waist circumference, waist to hip ratio (WHR), lipid profile, HOMA-IR, fasting insulin and insulin measurements during OGTT, and negatively correlated with FGIR, QUICKI, OGIS, and the Matsuda index. Obese children with the TG/HDL-C ratio≥3 (47.5%) had higher values of WHR and HOMA-IR, and lower ones of FGIR, QUICKI, OGIS, and the Matsuda index when compared to their obese peers with the TG/HDL-C<3. The area under the curve (AUC) calculated for each insulin resistance index in prediction of the metabolic syndrome was the largest for the TG/HDL-C ratio (0.8936, 95% Cl:0.809–0.977, p=0.000). For 1 unit increase in the TG/HDL-C ratio, the odds for having MS increased by 2.09 times. The TG/HDL-C ratio is a good surrogate marker of insulin resistance in obese children. When comparing the usefulness of some IR markers in prediction of the metabolic syndrome, the TG/HDL-C ratio seems to be the best one and should be used in clinical practice to identify children at risk of metabolic syndrome development.

Purpose: This paper is anchored on the findings of a study that sought to assess the availability of interpretation media in movie induced tourism and its effect on tourists’ satisfaction in Kenya.

Methodology: The study adopted explanatory and descriptive research designs. The study targeted 1,318 tourists from Karen Blixen Museum where the movie “Out of Africa” was filmed and Samburu County where the movie “The White Maasai” was filmed. In addition, a total of 658 bloggers airing their views on the filming locations were targeted. Simple random sampling and convenience sampling techniques were used to sample 345tourists and 221 bloggers, respectively. Structured closed-ended questionnaires were employed in collecting data.

Main Findings: Findings from regression model showed that interpretation services had a positive and significant effect on tourists satisfaction (β = 0.647, p< 0.000).Based on the study findings and subsequent discussions, this paper concludes that the availability of interpretation media is effective in enhancing tourists’ understanding and appreciation of the destination being visited. Specifically, availability of guards in Karen Blixen Museum and Samburu and other interpretation media enhanced tourist experience and a majority were satisfied. 

Implications: The findings can be used to improve practice by encouraging tour guides to have a clear knowledge of a destination to be able to guide tourist and facilitate the offering of quality products. It is therefore important to have interpretation services since they contribute to tourist satisfaction.

Novelty: The study contributes to the creation of additional knowledge to the field of movie-induced tourism thus enhancing the understanding of the nature and characteristics of movie-induced tourism.
The role of appropriate design and colour in reducing aggressive behaviour of customers
Authors: Yondem Ilkyaz Ariz
Published: November 2018

The basic philosophy of interior designing is to provide the users with facilities that are aesthetically appealing, easy to maintain and environmentally safe as well as operationally efficient. Though design envisages the combination of an array of elements, among them the most prominent one is colour and its appropriate utilisation in the design. Also, colour has the ability to influence human emotions, moods and feelings of individuals; therefore, it has a significant role in making the design effective. This study evaluates the influence of colour and design in triggering aggressive impulses in patrons, whose stress levels are compounded by factors such as drunkenness and physical environment. In addition to these research studies, Baker-Miller Pink, which is recommended for reducing aggressive behaviour and physical strength of prisoners in holding cells, will be assessed for usability in bar and pubs to reduce the stress levels of drunken customers and to encourage them to conduct peacefully.Keywords: Tranquillising effect of colour, interior design, aggression, pub and bars.

Merkez-çevre paradigması yöneten-yönetilen ayrımını değerler sistemi üzerinden tanımlar. Buna Göre her toplumun bir merkezi vardır. Bu merkez halkın büyük bir çoğunluğu tarafından kabul edilen ve bürokratik elit tarafından korunan değerlerden oluşur. Merkez tek ve değişmezidir. Tek ve değişmez olan merkezin karşısında ise çevre yer alır. Paradigma bürokratik eliti merkezin değerlerinin koruyucusu olarak kabul eder.

Paradigma, sistemin kırılma noktalarını açıklamadaki yetkinliği sayesinde Türk siyasal hayatının hâkim paradigması konumuna gelmiştir. Bununla birlikte paradigmanın 2000 sonrası Türkiye siyasetini açıklama noktasında yetersiz kaldığı yönünde eleştiriler de söz konusudur.

Yükseköğretim bürokrasisi, askerî bürokrasi ve yargı bürokrasisi Türkiye'de bürokratik elitin en önemli aktörleridir. Bu çalışmada, Adalet ve Kalkınma Partisi iktidarının yargı ve yükseköğretim bürokrasisi ile olan ilişkisi ele alınacaktır. Bu bürokratik kadrolarda Adalet ve Kalkınma Partisi iktidarının ikinci dönemi ile birlikte başlayan değişim merkez-çevre paradigmasına yöneltilen eleştirileri güçlendirmektedir. Bu bağlamda literatür taraması ve derinlemesine arşiv araştırması sonucu elde edilen bilgilerle geleneksel bürokratik yapının değişimi ve bu değişimin sonuçları ortaya konarak, Türkiye siyasetinde geleneksel merkezin dönüştüğü fikri işlenecektir.
On the Evolutionary Form of the Constraints in Electrodynamics
Authors: Rácz István
Published: November 2018

The constraint equations in Maxwell theory are investigated. In analogy with some recent results on the constraints of general relativity it is shown, regardless of the signature and dimension of the ambient space, that the "divergence of a vector field" type constraints can always be put into linear first order hyperbolic form for which global existence and uniqueness of solutions to an initial-boundary value problem is guaranteed.

This work demonstrates that a plasmid can function as an efficient biocatalyst in mediating the nitroaldol (Henry) reaction at high temperatures in ultrapure water. Compared with ssDNA, the plasmid displayed a remarkable catalytic efficiency (97% yield within 20 min). Aromatic aldehydes which bear strong or moderate electron-withdrawing groups reacted satisfactorily with nitromethane, which afforded the corresponding β-nitroalcohols in good yields within 2 h (up to 98%). By contrast, aliphatic and aromatic aldehydes with electron-donating groups did not react. Moreover, the yield significantly dropped when the size of the carbanion increased, and the yield was only 10% when nitropropane was used as the donor.

Detection of the region of interest (ROI) is a critical step in laryngeal image analysis for the delineation of glottis contour. The process can improve both computational efficiency and accuracy of the image segmentation task, which will facilitate subsequent analysis and characterization of the vocal fold vibration as it correlates with voice quality and pathology. This study aims to develop machine learning based approaches for automatic detection of ROI for glottis image sequences captured by high-speed video-endoscopy (HSV), a clinical laryngeal imaging modality. In particular, we first applied the supporting vector machine (SVM) method using histogram of oriented gradients (HOG) feature descriptor, and second, trained a convolutional neural network (CNN) model for this task. Comparisons are made for both approaches in terms of accuracy of recognition and computation time.
Environmental Regulation, Upgrading of Industrial Structure and Economic Fluctuation
Authors: Zhang Dan , Chen Leyi
Published: November 2018

This paper utilizes dynamic panel threshold technology to conduct a nonlinear test on the direct effect between environmental regulation and economic fluctuations and the effect of industrial structure upgrading by taking 35 industrial sectors in China from 2003 to 2016 . The research has found that there is an inverted "U" relationship between environmental regulation and economic fluctuations, with the enhancement of environmental regulations, the economic fluctuation increases first and then decreases. The cross-terms of environmental regulation and industrial structure rationalization or industrial structure upgrading are significantly negative, which indicates that the enhancement of environmental regulation is conducive to promoting industrial structure upgrading and reducing the economic fluctuations. While the rationalization factors of industrial structure and advanced industrial structure are significantly negative, indicating that both forms of industrial structure upgrading are conducive to reducing the economic fluctuations. Environmental regulation has technical innovation thresholds for industrial structure upgrading and economic fluctuations, but there are no human capital or FDI thresholds. In the rationalization model of industrial structure, there is a nonlinear "U" relationship between environmental regulation and economic fluctuations when the proportion of scientific research expenditure is more than 1.35%. With the enhancement of environmental regulation, the economic fluctuation reduces first and then increases, and the corresponding inflection point value is 2.398% of the environmental regulation level. At the same time, the environmental regulation can indirectly reduce economic fluctuations by pushing down the industrial structure upgrades. In the advanced model of industrial structure, there is a “U” relationship between environmental regulation and economic fluctuation when the proportion of scientific research expenditure is greater than 1.26%. With continuous enhancement of environmental regulation, the economic fluctuation reduces first and then increases. The corresponding inflection point value is 1.78% of the environmental regulation level, and environmental regulation can indirectly reduce economic fluctuations by promoting the industrial structure at the same time.
Cell-Based Fish: A Novel Approach to Seafood Production and an Opportunity for Cellular Agriculture
Authors: Rubio Natalie , Datar Isha , Stachura David , Krueger Kate
Published: November 2018

Cellular agriculture is defined as the production of agricultural products from cell cultures rather than from whole plants or animals. With growing interest in cellular agriculture as a means to address the public health, environmental, and animal welfare challenges of animal agriculture, the concept of producing seafood from fish cell- and tissue-cultures is emerging as a means to address similar challenges with industrial aquaculture systems and marine capture. Cell-based seafood - as opposed to animal-based seafood - can combine developments in biomedical engineering with modern aquaculture techniques. Biomedical engineering developments such as closed-system bioreactor production of land animal cells create a basis for large scale production of marine animal cells. Aquaculture techniques such as genetic modification and closed system aquaculture have achieved marked gains in production that can pave the way for innovations in cell-based seafood production. Here, we present the current state of innovation relevant to the development of cell-based seafood across multiple species as well as specific opportunities and challenges that exist for advancing this science. The authors find that the physiological properties of fish cell- and tissue- culture may be uniquely suited to cultivation in vitro. These physiological properties, including hypoxia tolerance, high buffering capacity, and low-temperature growth conditions, make marine cell culture an attractive opportunity for scale production of cell-based seafood; perhaps even more so than mammalian and avian cell cultures for cell-based meats. This, coupled with the unique capabilities of crustacean tissue-friendly scaffolding such as chitosan, a common seafood waste product and mushroom derivative, presents great promise for cell-based seafood production via bioreactor cultivation. To become fully realized, cell-based seafood research will require more understanding of fish muscle culture and cultivation; more investigation into serum-free media formulations optimized for fish cell culture; and bioreactor designs tuned to the needs of fish cells for large scale production.
