Published: December 2020

A salient objective feature of the social environment in which people find themselves is group size. Knowledge of group size is highly relevant to behavioural scientists given that humans spend considerable time in social settings and the number of others influences much of human behaviour. What size of group do people actually look for and encounter in everyday life? Here we report four survey studies and one experience-sampling study (totalN= 4,398) which provide evidence for the predominance of the dyad in daily life. Relative to larger group sizes, dyads are most common across a wide range of activities (e.g., conversations, projects, holidays, movies, sports, bars) obtained from three time moments (past activities, present, and future activities), sampling both mixed-sex and same-sex groups, with three different methodological approaches (retrospective reports, real-time data capture, and preference measures) in the United States and the Netherlands. We offer four mechanisms that may help explain this finding:reciprocity,coordination,social exclusion, andreproduction. The present findings advance our understanding of how individuals organize themselves in everyday life.

Published: December 2020

Purpose

Chronic pelvic pain syndrome (CPPS) is one of the most common outpatient urological diagnoses, and its incidence is increasing. Extracorporeal shockwave therapy (ESWT) has been suggested for relieving local perineal symptoms associated with chronic prostatitis/CPPS. Despite several treatment methods, no causal or standardized treatment is available for CPPS. This study aimed to investigate the efficacy and safety profile of ESWT for the treatment of chronic non-bacterial prostatitis.

Materials and methods

Studies were collected using four search engines (Pubmed, Cochrane, ScienceDirect, and EBSCOHost), on May 16, 2020; and assessed based on predetermined inclusion and exclusion criteria. Two reviewers performed study selection. Studies were then analyzed using Review Manager 5.3 for the meta-analysis.

Results

Seventy-four publications were initially retrieved, and three studies were considered for both qualitative and quantitative analyses. From these studies, we found that the use of ESWT was significantly associated with decreased pain domain (mean difference: -3.93; 95% confidence interval [CI] -5.13, -2.73; p<0.001), improved urinary score (mean difference: -1.79; 95% CI -2.38, -1.21; p<0.001), improved quality of life (mean difference: -1.71; 95% CI -2.12, -1.31; p<0.001), and improved National Institutes of Health chronic prostatitis symptom index (NIH-CPSI) score (mean difference: -5.45; 95% CI -5.74, -5.16; p<0.001) after 12 weeks of treatment.

Conclusion

ESWT is efficacious and safe in reducing pain and improving urinary condition, NIH-CPSI score, and quality of life in patients with chronic non-bacterial prostatitis.
Identification of urban land use efficiency by indicator-SDG 11.3.1

Published: December 2020

Inefficiency in urban land use is one of the problems caused by rapid urbanization. The UN Sustainable Development Goals (SDGs) indicator 11.3.1 is designed to test urban land use efficiency. This study employed geospatial and statistical data to compute land use efficiencies from 1990 to 2015 with five 5-year and ten 15-year intervals in Wukang, center of Deqing County, China. A flowchart was designed to extract the built-up lands from multiple data sources. The produced built-up lands were demonstrated to provide good accuracy by constructing an error matrix between the extracted and manually interpreted built-up lands as classified and reference images, respectively. By using the model provided by UN metadata to calculate SDG 11.3.1, the land use efficiencies from 1990 to 2015 were identified in Wukang. Our results indicate that the land use efficiency in Deqing County center is lower than the average of cities around the world, primarily because our in-situ study focused on a county center with larger rural regions than urban areas. Over the long term, urban land use becomes denser as the population grows, which will have a positive impact on the sustainability of urban development. This work is helpful for the local government to balance urban land consumption and population growth.
Modeling the relationship between estimated fungicide use and disease-associated yield losses of soybean in the United States II: Seed-applied fungicides vs seedling diseases

Published: December 2020

Use of seed-applied fungicides has become commonplace in the United States soybean production systems. Although fungicides have the potential to protect seed/seedlings from critical early stage diseases such as damping-off and root/stem rots, results from previous studies are not consistent in terms of seed-applied fungicide’s ability to mitigate yield losses. In the current study, the relationship between estimated soybean production losses due to seedling diseases and estimated seed-applied fungicide use was investigated using annual data from 28 soybean growing states in the U.S. over the period of 2006 to 2014. National, regional (northern and southern U.S.), state, and temporal scale trends were explored using mixed effects version of the regression analysis. Mixed modeling allowed computing generalized R2 values for conditional (R2GLMM(c); contains fixed and random effects) and marginal (R2GLMM(m); contains only fixed effects) models. Similar analyses were conducted to investigate how soybean production was related to fungicide use. National and regional scale modeling revealed that R2GLMM(c) values were significantly larger compared to R2GLMM(m) values, meaning fungicide use had limited utility in explaining the national/regional scale variation of yield loss and production. The state scale analysis revealed the usefulness of seed-applied fungicides to mitigate seedling diseases-associated soybean yield losses in Illinois, Indiana, North Carolina, and Ohio. Further, fungicide use positively influenced the soybean production and yield in Illinois and South Dakota. Taken together, use of seed-applied fungicide did not appear to be beneficial to many of the states. Our findings corroborate the observations made by a number of scientists through field scale seed-applied fungicide trials across the U.S and reiterate the importance of need base-use of seed-applied fungicides rather than being a routine practice in soybean production systems.
Validation of the Multicultural Personality Questionnaire Short Form (MPQ-SF) for use in the context of international education
Authors: Hofhuis Joep , Jongerling Joran , Van der Zee Karen I. , Jansz Jeroen
Published: December 2020

The Multicultural Personality Questionnaire (MPQ) is one of the most widely used instruments for measuring individuals’ intercultural competences. The original version consists of 91 items, divided into five subscales, and has been shown to predict attitudes, behavior, and outcomes in a variety of intercultural contexts. Recently, a 40-item short form of the MPQ was developed (MPQ-SF), which may be particularly useful in settings in which time or survey space are limited, or where respondent drop-out is likely to occur. For example, the MPQ-SF would be a valuable tool for assessing longitudinal development of multicultural personality traits in training or educational settings. A prerequisite for such research is to establish measurement invariance of the MPQ-SF between different respondent groups, as well as across time points. Using a sample of students in an international university program (n = 519), the present study examines how the scales perform among male and female respondents, between students of Western and Non-Western background, and across two time points, five months apart. Based on our findings, we conclude that all five subscales of the MPQ-SF display sufficient measurement invariance to be reliably used in this and similar contexts, in comparative as well as longitudinal study designs.

Published: December 2020

Arrhythmias have been reported frequently in COVID-19 patients, but the incidence and nature have not been well characterized. Patients admitted with COVID-19 and monitored by telemetry were prospectively enrolled in the study. Baseline characteristics, hospital course, treatment and complications were collected from the patients’ medical records. Telemetry was monitored to detect the incidence of cardiac arrhythmias. The incidence and types of cardiac arrhythmias were analyzed and compared between survivors and non-survivors. Among 143 patients admitted with telemetry monitoring, overall in-hospital mortality was 25.2% (36/143 patients) during the period of observation (mean follow-up 23.7 days). Survivors were less tachycardic on initial presentation (heart rate 90.6 ± 19.6 vs. 99.3 ± 23.1 bpm, p = 0.030) and had lower troponin (peak troponin 0.03 vs. 0.18 ng/ml. p = 0.004), C-reactive protein (peak C-reactive protein 97 vs. 181 mg/dl, p = 0.029), and interleukin-6 levels (peak interleukin-6 30 vs. 246 pg/ml, p = 0.003). Sinus tachycardia, the most common arrhythmia (detected in 39.9% [57/143] of patients), occurred more frequently in non-survivors (58.3% vs. 33.6% in survivors, p = 0.009). Premature ventricular complexes occurred in 28.7% (41/143), and non-sustained ventricular tachycardia in 15.4% (22/143) of patients, with no difference between survivors and non-survivors. Sustained ventricular tachycardia and ventricular fibrillation were not frequent (seen only in 1.4% and 0.7% of patients, respectively). Contrary to reports from other regions, overall mortality was higher and ventricular arrhythmias were infrequent in this hospitalized and monitored COVID-19 population. Either disease or management-related factors could explain this divergence of clinical outcomes, and should be urgently investigated.
Phylogenomics of 8,839 Clostridioides difficile genomes reveals recombination-driven evolution and diversification of toxin A and B

Published: December 2020

Clostridioides difficile is the major worldwide cause of antibiotic-associated gastrointestinal infection. A pathogenicity locus (PaLoc) encoding one or two homologous toxins, toxin A (TcdA) and toxin B (TcdB), is essential for C. difficile pathogenicity. However, toxin sequence variation poses major challenges for the development of diagnostic assays, therapeutics, and vaccines. Here, we present a comprehensive phylogenomic analysis of 8,839 C. difficile strains and their toxins including 6,492 genomes that we assembled from the NCBI short read archive. A total of 5,175 tcdA and 8,022 tcdB genes clustered into 7 (A1-A7) and 12 (B1-B12) distinct subtypes, which form the basis of a new method for toxin-based subtyping of C. difficile. We developed a haplotype coloring algorithm to visualize amino acid variation across all toxin sequences, which revealed that TcdB has diversified through extensive homologous recombination throughout its entire sequence, and formed new subtypes through distinct recombination events. In contrast, TcdA varies mainly in the number of repeats in its C-terminal repetitive region, suggesting that recombination-mediated diversification of TcdB provides a selective advantage in C. difficile evolution. The application of toxin subtyping is then validated by classifying 351 C. difficile clinical isolates from Brigham and Women’s Hospital in Boston, demonstrating its clinical utility. Subtyping partitions TcdB into binary functional and antigenic groups generated by intragenic recombinations, including two distinct cell-rounding phenotypes, whether recognizing frizzled proteins as receptors, and whether it can be efficiently neutralized by monoclonal antibody bezlotoxumab, the only FDA-approved therapeutic antibody. Our analysis also identifies eight universally conserved surface patches across the TcdB structure, representing ideal targets for developing broad-spectrum therapeutics. Finally, we established an open online database (DiffBase) as a central hub for collection and classification of C. difficile toxins, which will help clinicians decide on therapeutic strategies targeting specific toxin variants, and allow researchers to monitor the ongoing evolution and diversification of C. difficile.
Design prototyping as a translational tool for medical device commercialization
Authors: Page Rowan , John Kieran
Published: December 2020

Translational design is an increasingly important objective for universities as research institutions are seeking to play a more active role in the commercialization of fundamental medical research. Practice-based designers working within these academic contexts have a skill set that positions them to make a contribution to translating fundamental research into real-world applications. Real world applications of research that are informed by the needs of end-users and actioned through the creation of medical device prototypes. The translational designer’s toolkit includes a range of methodologies, frameworks, procedures and processes to identify problems, conceptualize ideas and create functional prototypes. Progressing research towards commercialization through prototyping is one of the most important skills leveraged by translational design researchers. This article details two case studies of practice-based design research within a large Australian university. It discusses the role of design prototyping as a key part of a lean and integrated development process that relies on accumulative rounds of iteration and interdisciplinary collaboration mediated through artefacts. Design prototyping is used within these projects to bring ideas to life and enable more effective communication between diverse stakeholder groups spanning across academia and industry, and across the boundaries of research and application. This article unpacks the key role of prototyping as a translational tool to iteratively test, refine and conceptually verify ideas, while additionally providing boundary objects for effective communication. This discussion addresses the benefits and limitations of prototyping as a translational tool, including the ability of prototyping to save time and development costs, explore constraints and trade-offs, and communicate with industry partners and end-users through tactile objects and/or real experiences. Design prototyping is an efficient and effective process that embraces failure in early stages of development, where the consequences are limited and the benefit substantial. The article explores how prototyping can provide the backbone to industrial design researchers working in translational contexts to drive development to real-world application and to effectively engage with research end-users.
Blurred lines: Practical and theoretical implications of a DAW-based pedagogy
Authors: Walzer Daniel
Published: December 2020

Digital audio workstations (DAWs) occupy a prominent space in the creative arts. Songwriters, composers, producers, and audio engineers use a combination of software and virtual instruments to record and make music. Educators increasingly find DAWs useful for teaching concepts in signal flow, acoustics and sound synthesis, and to model analogue processes. As the creative industries shift to primarily software-based platforms, the identities, roles, and responsibilities of the participants intersect and blur. Similarly, networked technologies change the space and place of creative activity. Now, the ‘studio’ exists virtually anywhere. For educators working with students, these changing paradigms present a series of challenges. This article explores the DAW’s possibilities across three areas: space and place, theory and identity, and pedagogy. The article advocates for a less technocratic model of teaching and learning with DAWs in favour of an approach that cultivates a balance of aesthetic awareness and creativity.

Published: December 2020

Introduction: Our aim was to evaluate the dietary intake and anthropometric indices in medical students with positive family history of type 2 diabetes (FH-T2D)(+) and without FH-T2D(-).Material and methods: 144 students were analyzed in this cross-sectional, observational study, conducted during the 2017-2018 school year using interviews and 7-day food diary. The participants were characterized anthropometrically. Waist-to-hip ratio (WHR) and waist-to-height ratio (WHtR), corrected mid-arm muscle area (MAMA), fat arm index (FAI), and tricipital skinfold (TSF) were calculated. Results: we found that 79.2% (95%CI: 72.5- 85.8) had FH-T2D. BMI was significantly higher in the participants with FH-T2D than without (23.7±3.8 v 25.0±3.7, respectively, p<0.05). No significant differences were determined in the indices based on central fat distribution (WHtR and WHR), peripheral distribution (FAI and TSF), or muscle mass (MAMA), when stratified by FH-T2D. Regarding dietary intake, when comparing participants with and without FH-T2D, respectively, we observed low/none legume consumption [30% (95%CI: 21.4-38.2) vs 23% (95%CI: 8.2-38.5)], diets high in proteins [38.6% (95%CI: 29.7-47.5) vs 46.7% (95%CI: 28.8-64.5)], low in carbohydrates [84.2% (95%CI: 77.5-90.9) vs 83.3% (95%CI: 70.0-96.7)], and insufficient energy intake [64% (95%CI: 55.2-72.8) vs 56.7% (95%CI: 38.9-74.4)], where the alterations in the dietary pattern were more detrimental for the FH-T2D(+) group. Lastly, the participants with FH-T2D consumed mainly late in the day [60% (95%CI: 50.6-68.6) vs 54% (95%CI: 35.5-71.2)].Conclusions: Even though there were minimal significant differences with the consumption by food categories, those students with FH-T2D presented with a poor, little varied and unbalanced dietary pattern with energy consumption mainly at night. These factors, if prolonged, could increase the risk of developing type 2 diabetes.

Published: December 2020

INTRODUCTION

We developed the strength training intervention (STRIVE), a home-based exercise program targeting physical function in patients with cirrhosis. In this pilot study, we aimed to evaluate the safety and efficacy of STRIVE.

METHODS

Eligible were adult patients with cirrhosis at 3 sites. Patients were randomized 2:1–12 weeks of STRIVE, a 30-minute strength training video plus a health coach or standard of care (SOC). Physical function and quality of life were assessed using the Liver Frailty Index (LFI) and Chronic Liver Disease Questionnaire (CLDQ), respectively.

RESULTS

Fifty-eight and 25 were randomized to STRIVE and SOC arms, respectively: 43% women, median age was 61 years, MELDNa, Model for End-Stage Liver Disease Sodium was 14, and 54% were Child-Pugh B/C. Baseline characteristics were similar in the STRIVE vs SOC arms except for rates of hepatic encephalopathy (19 vs 36%). LFI @ 12 weeks was available in 43 STRIVE and 20 SOC participants. After 12 weeks, the median LFI improved from 3.8 to 3.6 (ΔLFI −0.1) in the STRIVE arm and 3.7 to 3.6 (ΔLFI −0.1) in the SOC arm (P = 0.65 for ΔLFI difference). CLDQ scores improved from 4.6 to 5.2 in STRIVE participants (ΔCLDQ 0.38) and did not change in SOC participants (4.2–4.2; ΔCLDQ −0.03) (P = 0.09 for ΔCLDQ difference). One patient died (SOC arm) of bleeding. Only 14% of STRIVE participants adhered to the strength training video for 10–12 weeks. No adverse events were reported by STRIVE participants.

DISCUSSION

STRIVE, a home-based structured exercise program for patients with cirrhosis, was safely administered at 3 sites, but adherence was low. Although all participants showed minimal improvement in the LFI, STRIVE was associated with a substantial improvement in quality of life.
A Covid-19 e as perturbações no presentismo

Como e se a pandemia do coronavírus provocou uma mudança nas temporalidades que atravessam nosso cotidiano é o que este artigo se propõe analisar. Colocada sob o signo de uma urgência, que nos levou em poucos dias até o "estado de emergência sanitária”, a suspensão das atitudes corporais ordinárias (perigosas) e sua substituição por outras (todas, por sua vez, defensivas e protetivas) deveriam operar, como é normal no regime presentista, instantaneamente ou quase. Desde Hipócrates, cabe à medicina reconhecer que a doença tem, ela também, uma temporalidade própria. Sob a desordem aparente da doença, há de fato uma ordem que identifica o olho treinado do médico: uma ordem do tempo. O tempo da pandemia conduziu à instauração de um tempo novo, aquele do confinamento: tempo sanitário, já que o confinamento é o único instrumento à nossa disposição, diz a medicina, para retardar, frear a progressão do vírus, para que a curva exponencial cesse sua implacável ascensão. Nesse ponto, surgem inevitáveis conflitos de temporalidades que pedem arbitragens. A questão da nomeação do acontecimento é central. Epidemia, pandemia, sim, mas nós ficamos na esfera da medicina. A questão é saber se a grande crise que atravessa o mundo é uma oportunidade, um kairos, que, interrompendo as temporalidades habituais do tempo chronos, poderia abrirse sobre um novo tempo.

Proponho neste artigo analisar o humor racista midiático para tensionar os sentidos atribuídos à palavra “brincadeira” como algo sem intenção ofensiva quando associada à comicidade. Interessa-me discutir os desenhos risíveis do corpo negro como encarceramento, situando-o numa determinada posição social, cultural e política. Desenvolverei esse argumento relacionando três perspectivas: a comicidade racista, as disputas de sentido do riso como brincadeira e como as emoções circulam essa gargalhada, nas figuras da dor e do ódio para desenhar o corpo negro como feio, animal e criminoso
Um leitor no sul do mundo: a biblioteca imaginária de Simões Lopes Neto (1888-1916)

Published: December 2020

O escritor regionalista João Simões Lopes Neto deixou vários testemunhos de leitura, através de citações e referências, em toda sua produção, inclusive na prosa de ficção que o consagrou: Contos gauchescos (1912) e Lendas do Sul (1913). A partir dessa “biblioteca imaginária”, pretendo analisar seu perfil leitor, em suas condições de possiblidade, e discutir a circulação de ideias na fronteira sul do Brasil. Metodologicamente, busco aliar análises quantitativas e qualitativas que ofereçam explicações para suas tendências de leitura, mas também para algumas ausências significativas entre os autores citados. Como resultado, é possível traçar correspondências entre as leituras principais e sua prática de escrita de ficção (historiografia, nos temas, e poesia lírica, na linguagem), além de suas respostas para os problemas fundamentais do campo de produção cultural na região à época: os mitos do gaúcho e da Farroupilha.
Eugénia Melo e Castro e o Clube da Esquina: o sonho de uma canção luso-brasileira-múndi
Authors: De Andrade Pacheco Mateus
Published: December 2020

Durante os encontros da cantoracompositora portuguesa Eugénia Melo e Castro com os músicos brasileiros Wagner Tiso, Milton Nascimento e Novelli, no princípio da década de 1980, floresce um animado debate em torno de uma busca conjunta de linguagens desafiadoras de padrões musicais reconhecidos e consagrados artisticamente. Em tal cenário, os artistas se sentem estimulados a se reinventar, numa convergência de ritmos, interpretações e dicções, desenhando reflexões sobre uma música ancorada em sonoridades plurais e no sentimento de pertença ao mundo. Na medida em que se intensificam as discussões, outras presenças artísticas são convocadas, tais como as dos portugueses Sérgio Godinho e do grupo Trovante, além de vozes brasileiras, trazidas à cena por alguma lembrança anedótica, algum detalhe musical ou até mesmo alguma sonoridade familiar que invade alguma criação momentânea.

Documentos de um arquivo podem ser utilizados por professores e estudantes dos anos iniciais do Ensino Fundamental para estudos históricos escolares? Quais são as potencialidades e os limites da escola se constituir em um espaço de produção de conhecimento? Essas e outras questões motivaram intensos debates nas últimas décadas acerca de concepções curriculares e práticas pedagógicas. A partir da problematização de tendências culturais prevalecentes na vida social que afetam as experiências vividas dos sujeitos na contemporaneidade, este artigo propõe reflexões em torno das possibilidades de se desenvolverem, no âmbito do ensino de História, práticas educacionais transformadoras relativas à utilização de documentos de arquivos por integrantes da Educação Básica. Dialogando com referenciais teórico-metodológicos da história cultural,  coordenamos  um  projeto  de extensão comunitária que contou com a participação de escolas públicas da cidade de Campinas, da Faculdade de Educação e do Centro de Memória - Unicamp (CMU). Ao trabalharmos com questões que abarcavam a história local, a memória e patrimônio cultural, observamos que as relações estabelecidas entre professores, estudantes e documentos textuais e iconográficos do CMU proporcionaram instigantes articulações com suas visões de mundo, evidenciadas pelos múltiplos modos de leitura, apropriação e produção de conhecimento. Nesse sentido, questionamos a suposta necessidade de acúmulo de informação criada pelas sociedades modernas e ressaltamos a importância das experiências vividas para a constituição de novas perspectivas de espacialidade e temporalidade, capazes de se contrapor e superar cenários compostos por diferentes formas de exclusão social, desenraizamentos culturais e de crise de identidades.

State Incentivizing of Investment Activity in the Resource Region: Far East of Russia Variant
Authors:   Economic Research Institute FEB RAS, Lomakina Natalia
Published: December 2020

The authors studied the actual policies and emerging effects of state incentivizing of investment activity instruments under the ‘new model’ of development for the Far East of Russia. There were shown the specifics of localizing investments in the resource region in shape of preferential regimes of Territories of Advanced Social and Economic Development (TAD or ASEZ Advanced Special Economic Zones) and also extraterritorial preferences as direct subsidies from the federal budget to infrastructure projects of strategically important investment projects and regional investment projects. The effects of these instruments employed in the Far Eastern Federal District in 2014–2020 demonstrate that the package of state measures formed for attracting investments and its separate elements (royalty benefits, the criterion of maximum attraction of private investments for every rouble of budget ones, etc.) have promoted investments mainly in extraction of minerals in the total surveyed range of support instruments. The outcome of these preferences was further growth of resource-based industries in the Far East economy structure (which to a certain extent predetermines the perspective economy structure of the macro region). The analysis of the rate of accumulation (a share of investments in the regional Gross Domestic Product) as a factor of economic growth showed that the majority of Far Eastern regions (except the mono-mineral Sakhalinskaya and Magadanskaya oblasts and the Chukotsky Autonomous Okrug) do not reassert the role of resource-based industries as key drivers for their economic growth which would have justified state incentives for extraction of mineral resources in particular. Certain modifications have been revealed in the very instruments of state incentives under the ‘new model’ of development in the Far East of Russia among which is a blurring of border lines between preferential territories to legitimize incentivizing of mineral companies; a changed (reduced) role of regional authorities in implementation of different instruments; forming ‘multi-layer’ preferences in the interest of mineral companies. It was demonstrated that in the surveyed contour of key actors interacting in the process of implementing different instruments of a ‘new model’ for development of the Far East of Russia (federal and regional administration, businesses) with greater vividness comes to the fore a tendency for shaping key outcomes of preferences in mineral companies

Published: December 2020

Differentiation in the level of socio-economic development of territories is largely manifested in both inter-regional and intra-regional differences in personal income and consumption of goods. In this regard the methods of hierarchical analysis (HLM, Hierarchical Linear Modeling) that make it possible to study variation at several levels taking into account both municipal and regional factors are acquiring special relevance. Along with hierarchical effects, neighborhood effects can be distinguished. This is possible due to the imposition of a spatial adjacency matrix on the data observing spatial interactions within the spatial-hierarchical models (HSAM, Hierarchical Spatial Autoregressive Modeling). The aim of the study is to better understand the relationship between consumption and personal income within a hierarchically structured and spatially oriented economic system. The analysis uses the data from 2319 municipalities (i.e. municipal districts or rayons) and urban districts (okrugs) in 84 constituent entities of the Russian Federation for 2018. It showed that 38.4% of the variation among municipalities in terms of sold foods volume is explained by regional factors. The developed hierarchical (two-level) model revealed the positive impact of the volume of social benefits and taxable personal income in the municipality, and the volume of per capita retail trade at the level of the Russian Federation constituent entities, on the volume of foods sold within municipalities, and substantiate the negative impact of the Gini index increase, as well as highlight the positive spatial effect

Life expectancy is one of the indicators used to evaluate the government’s performance in improving the well-being of the population. High life expectancy in an area indicates that people in the area have been assured of health and poverty has been well overcome, and vice versa. Based on national socioeconomic survey (SUSENAS) data, showing life expectancy in East Java Province from 2009 to 2013 increased by 69.15 years to 70,19 years. Although overall life expectancy in East Java province has increased, there are still some areas that have life expectancy below 65 years. This is not from the different characteristics of each religion. Therefore, the main purpose of this study is to model life expectancy in East Java using semiparametric regression with a mixed estimator of Spline Truncated and Fourier Series.  Based on the research that has been done, the results that modeling the data of life expectancy using mixed estimator of Spline Truncated and Fourier Series produced a value of R2 of 99,62% which means that the predictor variables are able to explain the response variabel life expectancy of 99.62%.

Farmer Exchange Rate (FER) is an indicator that can be used to measure the level of farmers welfare. For every agriculture sector, FER is affected by the historical price of harvest from the corresponding sector and historical prices of other agriculture sectors. In Central Java Province, rice & palawija, horticulture, and fisheries are the largest agriculture sectors which is the main livelihood for most of the population. FER forecasting is a crucial thing to determine the level of farmers welfare in the future. One method that can be used to predict the value of a variable that is influenced by the historical value of several variables is Vector Time Series. An empirical study was conducted using FER data from the rice & palawija, horticulture and fisheries sectors for January 2011-June 2017 in Central Java Province. The results obtained show that by using the VIMA(2.1) model, the FER prediction was very accurate, with MAPE values were 1.91% (rice & palawija sector), 2.44% (horticulture sector), and 2.18% (fisheries sector).

The purpose of this article is to give a general overview of the production technologies of stents with consideration of their design and materials. Since the beginning of the use of stents in medicine for atherosclerosis treatment, their development has changed rapidly. Various stents have also been developed with the development of materials science, treatment techniques and new manufacturing processes. In this way the development has shifted from the initial bare-metal stents (BMS), to drug-eluting stents (DES) and bio-resorbable stents (BRS), which are made of biodegradable polymers or metals. Various studies agree that it will be necessary to further review the experimentally obtained material properties with analytical and numerical studies. Here, the computational modelling (Finite element analysis - FEA and Computational fluid dynamics - CFD) was found as a valuable tool when evaluating stent mechanics and optimizing stent design. The development of the stent manufacturing technologies has also changed and been supplemented over the years. Nowadays, 3D printing could be an exciting manufacturing method to produce polymeric bio-materials, suitable for the latest generation of bio-degradable stents applications.

Technological processes play an essential task in the enterprise's production system. The behaviour and functioning of these systems cannot be predicted with certainty as they belong to a group of probable determinate structures. Generally, if we wanted to know precisely the behaviour of this condition in advance, we would have to be able to describe them mathematically or observe the action of the system on a real object. By applying discrete event simulation software, we realize the development of environmentally friendly products and using the simulation, we gain the certainty that the planned tasks can be implemented in a given time frame, while the simulation of the production process can help to clearly clarify and better understand the processes. To choose the optimal manufacturing ways of cleaning the fabrics component from waste tyres, we used the Witness discrete event simulation software to determine the usability and time occupancy of individual machines in the production of new fabric-based material. We simulated the ultrasonic method of cleaning the fabrics component from waste tyres and the subsequent creation of the test specimen. After the simulation, the obtained data can be used by a selection of type and number of machines and auxiliary equipment, by numbers of tools and fixtures, and by numbers of transport equipment. Obtained results bring the best layout of the workplace, the optimal dose of input materials and resources used in production. We have identified bottlenecks in the machines with long waiting times. The research priority was to reduce bottlenecks and increase the effectiveness of the entire of production line.
Optimal channel decision of retailers in the dual-channel supply chain considering consumer preference for delivery lead time

Facing competition from manufacturers' online direct channels, how retailers make sales channel decisions to increase consumer stickiness has become the core concern of the industry and academia. Empirical research showed that delivery lead time is a key factor that affects consumers' preference for online channels. To analyze the impact of consumer delivery time preference on channel selection and pricing strategy of retailers, consumer delivery lead time preference function was improved from a linear function to an exponential function and consumer demand under the mixed dual-channel supply chain of manufacturer and retailer was derived. Then, the Stackelberg game models under different channel strategies of retailer were established and solved. Results show that consumer preference for delivery lead time has four implications on the channel decision of retailers under manufacturer encroachment in the dual-channel supply chain. First, the dual retail channels strategy is the optimal choice for retailers, and the profit margins that a retailer obtains from dual retail channels supply chain and single online retail channel supply chain will increase as consumers' delivery lead time preference coefficient increases. Second, the optimal pricing of online retail channel and offline retail channel is positively related to consumers' delivery lead time preference coefficient. By contrast, the optimal pricing of online direct channel is negatively related to consumers' delivery lead time preference coefficient. Third, the optimal pricing of online retail channel is higher than that of offline retail and online direct channels. Fourth, a retailer and a manufacturer can adopt a compensation-based whole price contract to address the conflict brought about by the optimal channel choice of the retailer. This study introduces consumer delivery lead time preference into retailer channel decision making and provides a theoretical reference for retailer's mixed channel construction in practice.

THE CONCEPT OF TIME IN THE CONTEXT OF THE DIVERSITY OF HISTORICAL PROCESS
Authors: Poletaeva Yulia
Published: December 2020

It is argued that the concept of time determines the problematization of the historical process. The basis for such a formulation of the question is the purposeful human activity inextricably linked with the concept of time. The foundation for the solution of this issue was laid by M. Heidegger, who considers time as a possible horizon for questioning about being. History in this sense, being the task of the spirit or itself, becomes the sphere of human existence. The concept of linearity of time is associated with the finalist understanding of history. The problem of history, taking into account the concept of time, is solved through a fundamentally new interpretation of the role of a single, individual in the methodology of historical knowledge. It is stated that the methodological solution to the problem of history is to consider the concept of the individual (diverse) in history in the context of time.

Purpose. To assess the current hydrochemical characteristics of water in the Karpych Lake for determination of the possibilities for fish rearing. Methodology. The paper presents the results of determining the hydrochemical composition of water in the Karpych Lake, village Hvozdiv, Vasylkiv district, Kyiv region. The hydrochemical analysis was performed according to standard methods using the photometric method for determining pollutants in surface waters: concentration of ammonium nitrogen (with Nessler's reagent), nitrites (with Griss reagent), nitrates, phosphates (with ammonium molybdate) and total iron (with orthophenanthroline), the chloride content was determined by argentometric titration. The pH was determined electrometrically, and the content of sulfates and dry residue by gravimetric method. All above mentioned methods are key parameters in a comprehensive assessment of the ecological condition of the lake. Findings. The major ingredients of the hydrochemical composition of water, which characterize its physical properties (hydrogen index, suspended solids, hardness), salt (chlorides, sulfates, calcium, magnesium, sodium, bicarbonates), biogenic nitrogen (ammonium nitrogen, nitrites, nitrates), phosphates, iron were studied and analyzed in laboratory conditions. The results of laboratory measurements of the chemical composition of water samples, as well as the analysis of maximum allowable concentrations of substances for water bodies of fishery importance (MACrg) give grounds for certain conclusions of the current hydrochemical state of water of the studied lake Karpych. Originality For the first time, an assessment of the current hydrochemical characteristics of water in the Karpych Lake was conducted to determine the possibilities of fish rearing. Practical Value. The obtained results are necessary to establish the possibilities of using the Karpych Lake for growing and breeding commercial fish. Keywords: Karpich pond, hydrochemical parameters, assessment of hydrochemical condition of water bodies.
