Published: December 2020

Preeclampsia (PE) is a severe pregnancy complication, which may be considered as a systemic response in the second half of pregnancy to physiological failures in the first trimester, and can lead to very serious consequences for the health of the mother and fetus. Since PE is often associated with proteinuria, urine proteomic assays may represent a powerful tool for timely diagnostics and appropriate management. High resolution mass spectrometry was applied for peptidome analysis of 127 urine samples of pregnant women with various hypertensive complications: normotensive controls (n = 17), chronic hypertension (n = 16), gestational hypertension (n = 15), mild PE (n = 25), severe PE (n = 25), and 29 patients with complicated diagnoses. Analysis revealed 3869 peptides, which mostly belong to 116 groups with overlapping sequences. A panel of 22 marker peptide groups reliably differentiating PE was created by multivariate statistics, and included 15 collagen groups (from COL1A1, COL3A1, COL2A1, COL4A4, COL5A1, and COL8A1), and single loci from alpha-1-antitrypsin, fibrinogen, membrane-associated progesterone receptor component 1, insulin, EMI domain-containing protein 1, lysine-specific demethylase 6B, and alpha-2-HS-glycoprotein each. ROC analysis of the created model resulted in 88% sensitivity, 96.8% specificity, and receiver operating characteristic curve (AUC) = 0.947. Obtained results confirm the high diagnostic potential of urinary peptidome profiling for pregnancy hypertensive disorders diagnostics.

Published: December 2020

This study responds to the need to explore the individual characteristics that may help us to understand the levels of stress involved in the significant COVID-19-related restrictions to people’s daily lives. In order to understand levels of stress and stress control during the COVID-19 confinement, 1269 people from Spain (17.5% men) aged between 18 and 70 completed the Perceived Stress Scale (PSS-14). The results indicated that people aged under 40, and especially those under 25, women, and those on low incomes reported higher rates of confinement stress. The nature of where people live, and their working situation during confinement also contributed to people’s stress response, although with lower levels of impact. In this context, our study suggests that the levels of stress in those who combine remote working with in situ working were lower than those who had other working conditions. Our study contributes significant information to understanding the effects of confinement, and its results may be used to inform intervention tools and programs.
Empirically Investigating Extraneous Influences on the “APCO” Model—Childhood Brand Nostalgia and the Positivity Bias
Authors: Harborth David , Pape Sebastian
Published: December 2020

Pokémon Go is one of the most successful mobile games of all time. Millions played and still play this mobile augmented reality (AR) application, although severe privacy issues are pervasive in the app due to its use of several sensors such as location data and camera. In general, individuals regularly use online services and mobile apps although they might know that the use is associated with high privacy risks. This seemingly contradictory behavior of users is analyzed from a variety of different perspectives in the information systems domain. One of these perspectives evaluates privacy-related decision making processes based on concepts from behavioral economics. We follow this line of work by empirically testing one exemplary extraneous factor within the “enhanced APCO model” (antecedents–privacy concerns–outcome). Specific empirical tests on such biases are rare in the literature which is why we propose and empirically analyze the extraneous influence of a positivity bias. In our case, we hypothesize that the bias is induced by childhood brand nostalgia towards the Pokémon franchise. We analyze our proposition in the context of an online survey with 418 active players of the game. Our results indicate that childhood brand nostalgia influences the privacy calculus by exerting a large effect on the benefits within the trade-off and, therefore, causing a higher use frequency. Our work shows two important implications. First, the behavioral economics perspective on privacy provides additional insights relative to previous research. However, the effects of several other biases and heuristics have to be tested in future work. Second, relying on nostalgia represents an important, but also double-edged, instrument for practitioners to market new services and applications.
Experimental and Mathematical Tools to Predict Droplet Size and Velocity Distribution for a Two-Fluid Nozzle

Published: December 2020

Despite progress in laser-based and computational tools, an accessible model that relies on fundamentals and offers a reasonably accurate estimation of droplet size and velocity is lacking, primarily due to entangled complex breakup mechanisms. Therefore, this study aims at using the integral form of the conservation equations to create a system of equations by solving which, the far-field secondary atomization can be analyzed through predicting droplet size and velocity distributions of the involved phases. To validate the model predictions, experiments are conducted at ambient conditions using water, methanol, and acetone as model fluids with varying formulation properties, such as density, viscosity, and surface tension. Droplet size distribution and velocity are measured with laser diffraction and a high-speed camera, respectively. Finally, an attempt is made to utilize non-scaled parameters to characterize the atomization process, useful for extrapolating the sensitivity analysis to other scales. The merit of this model lies in its simplicity for use in process control and optimization.

Authors: Mills David K. , Luo Yangyang , Elumalai Anusha , Esteve Savannah , Karnik Sonali , Yao Shaomian
Published: December 2020

The development of distinct biomimetic microenvironments for regulating stem cell behavior and bioengineering human tissues and disease models requires a solid understanding of cell–substrate interactions, adhesion, and its role in directing cell behavior, and other physico-chemical cues that drive cell behavior. In the past decade, innovative developments in chemistry, materials science, microfabrication, and associated technologies have given us the ability to manipulate the stem cell microenvironment with greater precision and, further, to monitor effector impacts on stem cells, both spatially and temporally. The influence of biomaterials and the 3D microenvironment’s physical and biochemical properties on mesenchymal stem cell proliferation, differentiation, and matrix production are the focus of this review chapter. Mechanisms and materials, principally hydrogel and hydrogel composites for bone and cartilage repair that create “cell-supportive” and “instructive” biomaterials, are emphasized. We begin by providing an overview of stem cells, their unique properties, and their challenges in regenerative medicine. An overview of current fabrication strategies for creating instructive substrates is then reviewed with a focused discussion of selected fabrication methods with an emphasis on bioprinting as a critical tool in creating novel stem cell-based biomaterials. We conclude with a critical assessment of the current state of the field and offer our view on the promises and potential pitfalls of the approaches discussed.

Authors: Chen Jiangang , Zhou Yuan , Pan Xinliang , Li Xiaolong , Long Jiamin , Zhang Hui , Zhang Jing
Published: December 2020

Purpose: This cross-sectional study examined the associations between health-related physical fitness (HPF) and cardiovascular disease (CVD) risk factors in overweight and obese university staff. Methods: A total of 340 university staff (109 women, mean age 43.1 ± 9.7 years) with overweight (n = 284) and obesity (n = 56) were included. The HPF indicators included skeletal muscle mass index (SMI), body fat percentage (BFP), grip strength (GS), sit-and-reach test (SRT), and vital capacity index (VCI). CVD risk factors were measured, including uric acid (UA), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and glucose (GLU). Results: BFP, SMI, and GS were positively associated with UA level (β = 0.239, β = 0.159, β = 0.139, p < 0.05). BFP was positively associated with TG and TG/HDL-C levels (β = 0.421, β = 0.259, p < 0.05). GS was positively associated with HDL-C level (β = 0.244, p < 0.05). SRT was negatively associated with GLU level (β = −0.130, p < 0.05). Conclusions: In overweight and obese university staff, body composition, muscle strength, and flexibility were associated with CVD risk factors. An HPF test may be a practical nonmedical method to assess CVD risk.
The Strengthening of Masonry Walls in Seismic-Prone Areas with the CAM System: Experimental and Numerical Results
Authors: Recupero Antonino , Spinella Nino
Published: December 2020

In this paper, experimental and numerical results of a research project about the structural behavior of strengthened masonry are presented and discussed. The aim of the research is to study the in-plane shear behavior of an old masonry wall with an opening in the arch form, reinforced with a pioneering system of 3D pre-tensioned stainless steel ties. The masonry wall was in-plane loaded until first cracking appeared, then it was reinforced and re-loaded until failure. The experimental results have highlighted the benefits of the reinforcing method adopted, especially to provide an increasing in terms of both strength and ductility. Numerical modeling of the masonry wall behavior was accomplished by using non-linear finite-element methods generally adopted for reinforced concrete elements.
Digital Technologies and the Public Sphere in Spain: Spatial Metaphors, Viewers’ Perceptions and Demands in Light of the Democratic Challenge (2014–2017)
Authors: Broullón-Lozano Manuel A. , Lamuedra Graván María
Published: December 2020

During the 2010s, there was a “utopian moment” as regards the structure of media, owing to the social space created by digital culture, transmediality, and the different ways of participating in public debate. What is expected from digital information transmitted via the Web and social media is action and interaction with subjects in the public space or square. Accordingly, this paper analyses the descriptive assertions and proposals of the viewers of newscasts of Spanish television between 2014 and 2017, as regards how they perceived and represented the public space, mediatised by information through spatial metaphors. Specifically, it is based on the analysis of the transcriptions of five discussion groups and four interviews, whose aim is to examine two polarised spatial metaphors—the traffic labyrinth and the open square—and a series of demands relating to the role of journalists, media ownership, viewers’ access, and the quality of democratic society.
The Impact of Internationalization of the Boardroom on Capital Structure
Authors: Yousef Ibrahim , Almoumani Hanada , Samara Ihssan
Published: December 2020

We develop a theoretical model based on several theories, mainly pecking order theory and theory of information economics, as well as on theoretical arguments provided by economic sociology and psychology to investigate for the first time the impact of the presence of a foreign board member on capital structure. The sample of study covers 3773 non-financial U.S. firms and includes 23,196 observations over the period from 2010 to 2018. We used pooled OLS, fixed effects, random effects, and the general method of moments (GMM) in order to analyze the impact of foreign directors on capital structure after controlling for a range of factors, including size, year, and industry effects. The results of this empirical analysis support the proposed hypothesis. Of particular note is the finding that the proportion of foreign directors on the board correlates negatively with debt structure. Furthermore, we demonstrate that our findings hold up in the face of all appropriate robustness checks. Our study contributes to the existing literature by including an international dimension of board diversity, specifically the influence of foreign directors on corporate capital structure. We argue that increasing international diversity in the boardroom improves both the quantity and quality of the information exchange between insiders and shareholders, thereby reducing adverse selection costs.

Authors: Chevallier Julien
Published: December 2020

The original contribution of this paper is to empirically document the contagion of the Covid-19 on financial markets. We merge databases from Johns Hopkins Coronavirus Center, Oxford-Man Institute Realized Library, NYU Volatility Lab, and St-Louis Federal Reserve Board. We deploy three types of models throughout our experiments: (i) the Susceptible-Infective-Removed (SIR) that predicts the infections’ peak on 2020-03-27; (ii) volatility (GARCH), correlation (DCC), and risk-management (Value-at-Risk (VaR)) models that relate how bears painted Wall Street red; and, (iii) data-science trees algorithms with forward prunning, mosaic plots, and Pythagorean forests that crunch the data on confirmed, deaths, and recovered Covid-19 cases and then tie them to high-frequency data for 31 stock markets.
Residual Stress Reduction Technology in Heterogeneous Metal Additive Manufacturing
Authors: Hong Myoung-Pyo , Kim Young-Suk
Published: December 2020

Metal additive manufacturing (AM) is a low-cost, high-efficiency functional mold manufacturing technology. However, when the functional section of the mold or part is not a partial area, and large-area additive processing of high-hardness metal is required, cracks occur frequently in AM and substrate materials owing to thermal stress and the accumulation of residual stresses. Hence, research on residual stress reduction technologies is required. In this study, we investigated the effect of reducing residual stress due to thermal deviation reduction using a real-time heating device as well as changes in laser power in the AM process for both high-hardness cold and hot work mold steel. The residual stress was measured using an X-ray stress diffraction device before and after AM. Compared to the AM processing conditions at room temperature (25 °C), residual stress decreased by 57% when the thermal deviation was reduced. The microstructures and mechanical properties of AM specimens manufactured under room-temperature and real-time preheating and heating conditions were analyzed using an optical microscope. Qualitative evaluation of the effect of reducing residual stress, which was quantitatively verified in a small specimen, confirmed that the residual stress decreased for a large-area curved specimen in which concentrated stress was generated during AM processing.
Characterization of Crater Area in a Target Penetrated by a Wf/Zr-Based Amorphous Matrix Composite Projectile
Authors: Ye Xianghai , Zou Minming , Chen Jiankang
Published: December 2020

Tungsten fiber-reinforced Zr41.25Ti13.75Cu12.5Ni10Be22.5 amorphous matrix composites (hereinafter referred to as Wf/Zr-based amorphous matrix composites) are considered as a potential new generation of projectile material, while the penetration behavior of Wf/Zr-based amorphous matrix composites is not fully clear yet. In order to better understand the penetration behavior of this composite material and study its armor-piercing performance, a ballistic experiment was performed and the hardness and microstructure around the crater of a target material were studied. A ballistic experiment was performed with a projectile of Wf/Zr-based amorphous matrix composite and a target of 4043 steel. After the ballistic experiment, the target was cut through the crater using a wire cutting machine into a sample with size 150 mm × 40 mm × 20 mm, which was later polished by different types of sandpaper. The micro-hardness was analyzed in a micro-hardness tester, and the microstructure was observed by SEM. According to this study, three layers were identified in the direction lateral to the crater, consisting of a martensite layer, a deformation strengthening layer, and the original structure layer. Moreover, the martensite layer initially thickened and then thinned in the direction longitudinal to the crater.

Alternative Extraction and Characterization of Nitrogen-Containing Azaphilone Red Pigments and Ergosterol Derivatives from the Marine-Derived Fungal Talaromyces sp. 30570 Strain with Industrial Relevance
Authors: Lebeau Juliana , Petit Thomas , Fouillaud Mireille , Dufossé Laurent , Caro Yanis
Published: December 2020

Many species of Talaromyces of marine origin could be considered as non-toxigenic fungal cell factory. Some strains could produce water-soluble active biopigments in submerged cultures. These fungal pigments are of interest due to their applications in the design of new pharmaceutical products. In this study, the azaphilone red pigments and ergosterol derivatives produced by a wild type of Talaromyces sp. 30570 (CBS 206.89 B) marine-derived fungal strain with industrial relevance were described. The strain was isolated from the coral reef of the Réunion island. An alternative extraction of the fungal pigments using high pressure with eco-friendly solvents was studied. Twelve different red pigments were detected, including two pigmented ergosterol derivatives. Nine metabolites were identified using HPLC-PDA-ESI/MS as Monascus-like azaphilone pigments. In particular, derivatives of nitrogen-containing azaphilone red pigment, like PP-R, 6-[(Z)-2-Carboxyvinyl]-N-GABA-PP-V, N-threonine-monascorubramin, N-glutaryl-rubropunctamin, monascorubramin, and presumed N-threonyl-rubropunctamin (or acid form of the pigment PP-R) were the major pigmented compounds produced. Interestingly, the bioproduction of these red pigments occurred only when complex organic nitrogen sources were present in the culture medium. These findings are important for the field of the selective production of Monascus-like azaphilone red pigments for the industries.
Preschoolers’ STEM Learning on a Haptic Enabled Tablet
Authors: Pila Sarah , Piper Anne Marie , Lauricella Alexis , Wartella Ellen
Published: December 2020

The research on children’s learning of science, technology, engineering, and math (STEM) topics from electronic applications (apps) is limited, though it appears that children can reasonably transfer learning from tablet games to particular tasks. We were interested to determine whether these findings would translate to the emerging technology of haptic feedback tablets. The research on haptic feedback technology, specifically, has found that this type of feedback is effective in teaching physics concepts to older students. However, haptic feedback has not yet been sufficiently explored with younger groups (e.g., preschoolers). To determine the effect of playing a STEM game enhanced with haptic technology on learning outcomes, we designed an experiment where preschool participants were randomly exposed to one of three different conditions: (a) STEM game with no haptic feedback (tablet), (b) STEM game enabled with haptic feedback (haptics), or (c) a puzzle game (control). Results revealed no significant differences in comprehension or transfer by condition. Results from this study contribute to the literature on the effectiveness of haptic feedback for preschool STEM learning.
Personal Autonomy in a Post-Secular Society
Authors: Giovagnoli Raffaela
Published: December 2020

The contemporary philosophical debate on autonomy shows several interesting perspectives that emphasize the role of social contexts for developing this human capacity. There is a shift from the classical notion of “moral” autonomy to the wider notion of “personal autonomy”, and we underscore the “substantive view” that helps to provide arguments that support a plausible notion strictly connected with socialization and language use. In this article, we consider the source of autonomy that is represented by a communicative life-world in its ordinary and extra-ordinary dimensions to discuss the role of personal autonomy in a post-secular society. Moreover, we propose to adopt a pragmatic account to describe the social role of the autonomous agent in discursive contexts.
Surface Plasmon Resonance Sensor Based on Polymer Liquid-Core Fiber for Refractive Index Detection
Authors: Shui Xuqing , Gu Qiongchan , Jiang Xiaoxiao , Si Guangyuan
Published: December 2020

In this work, a surface plasmon resonance (SPR) sensor based on a novel liquid-core polymer optical fiber (POF) is proposed and numerically analyzed for refractive index (RI) detection. The polytetrafluoroethylene (PTFE) fiber is selected as the platform for SPR sensing. We combine the PTFE-based POF with the liquid-core structure by introducing a hole filled with analyte into the fiber center. The hole also acts as the fiber core to guide the incident light. This design helps to realize the detection of solutions with low RI values (around 1.33), while keeping the distinguished sensing characteristics of the liquid-core structure. Two side air holes are introduced into the cladding and a thin silver film protected by a titanium dioxide layer is plated on the wall of one air hole, which helps to control the mode coupling. In order to optimize the design of this sensor, the impacts of parameters such as metal layer thicknesses and the central hole radius are investigated using the full-vector finite element method (FEM). After optimization, our design shows a wavelength interrogation sensitivity reaching up to 16,750 nm/RIU and an average full-width at half-maximum (FWHM) of 42.86 nm in the RI range of 1.325–1.35.
Effects of Fluoride Exposure on Primary Human Melanocytes from Dark and Light Skin
Authors: Goenka Shilpi , Simon Sanford
Published: December 2020

Fluoride exposure has adverse effects on human health that have been studied in vitro in cell culture systems. Melanocytes are the melanin pigment-producing cells that have a significant role in the regulation of the process of melanogenesis, which provides several health benefits. Melanocytes are present in the oral cavity, skin, brain, lungs, hair, and eyes. However, to date, there has been no study on the effects of fluoride exposure on melanocytes. Hence, in the current study, we have studied the effects of sodium fluoride (NaF) exposure on neonatal human epidermal melanocytes (HEMn) derived from two different skin phototypes, lightly pigmented (LP) and darkly pigmented (DP). We have assessed the impact of a 24 h and 72 h NaF exposure on metabolic activity and membrane integrity of these cells. In addition, we have evaluated whether NaF exposure might have any impact on the physiological functions of melanocytes associated with the production of melanin, which is regulated by activity of the enzyme tyrosinase. We have also assessed if NaF exposure might induce any oxidative stress in LP and DP melanocytes, by evaluation of production of reactive oxygen species (ROS) and measurement of mitochondrial membrane potential (MMP) levels. Our results showed that HEMn-LP cells showed a higher sensitivity to NaF cytotoxicity than HEMn-DP cells, with significant cytotoxicity at concentrations >1 mM, while concentration range 0.25–1 mM were nontoxic and did not lead to oxidative stress, and also did not alter the levels of intracellular melanin or cellular tyrosinase activity, indicating that treatment up to 1 mM NaF is generally safe to melanocytes from both pigmentation phototypes.
Identifying the Best Alternative Tourism Product for a Destination: the case of Cappadocia
Authors: Karakuş Yusuf
Published: December 2020

Abstract: The key to success in management activities is the ability to make the best decision on the path to achieve the set goals. Decision makers can make scientific and more successful decisions by using Multi-criteria decision making techniques to overcome such problems. However, decision making becomes more difficult especially in the industry which has a very complex structure like tourism and hospitality. The main purpose this paper is to identify an alternative type of tourism that will serve the optimal advantages of the tourist destinations’ stakeholders. Cappadocia destination is considered within the scope of the study. Decision making at destination level is risky to decide for a tourism destination for many reasons such as high investment costs, long term results, high diversity of stakeholders, and diversity of decision makers and conflicts of interests. In this study, qualitative and quantitative methods were used as mixed via QFD and AHP. As a result of examining different criteria and alternatives in line with the opinions of different stakeholders, congress tourism option has emerged as the most suitable tourism product alternative. As a result, different alternatives sorted by importance and the question of where to start the work in accordance with the possibilities has been tried to be answered. In this context, it has been a guiding study for the practitioners who have decision-making difficulties. Since no similar study has been found, it is an inspiration for future studies.

The Effect of Customers’ Hotel Experience on Satisfaction: the mediating role of memorability
Authors: Çoban Ömer , Ardıç Yetiş Şule
Published: December 2020

Abstract: Nowadays, hotels have become places of life and experience areas rather than a place to sleep at night for customers. Customers' experiences during their stay at the hotel can effect their future behavior. Moreover, the memorability of these experiences can also effect these behaviors. However, there is little empirical evidence identifying and measuring the relationship between these variables. Hence, it has been investigated whether memorability plays a mediator role in the relationship between customers' hotel experiences and satisfaction levels in this research. For this purpose, a field survey conducted in Cappadocia region where the cave hotels operate intensively. The data was collected by pollsters in April, 2019. Within the scope of the research, 439 questionnaires were collected from tourists staying in cave hotels. The regression analysis based on Bootstrap method was used to test whether memorability plays a mediation role in the effect of consumer hotel experiences on satisfaction. In the light of the study's findings, it was found that memorability plays an indirect mediation role in the effect of hotel experience dimensions on satisfaction.

O Turismo na Favela do Vidigal: base comunitária ou base mercadológica?
Authors: Kalaoum Fausi , Elizabeth de Souza Santiago Patrícia
Published: December 2020

Esse trabalho teve como objetivo principal analisar criticamente a intensificação dos fluxos e ofertas turísticas que ocorreram na favela do Vidigal, localizada na Zona Sul do Rio de Janeiro, após a instalação da Unidade de Polícia Pacificadora (UPP) no ano de 2012, pelo viés do Turismo de Base Comunitária (TCB). A partir desse acontecimento, o Vidigal – favela vizinha de bairros como Ipanema, Leblon e Copacabana, conhecidas mundialmente como bairros turísticos – foi palco do crescimento não apenas da demanda, mas também da oferta turística. Assim, o principal questionamento a ser respondido por essa pesquisa foi “estaria a atividade turística no Vidigal apoiada nos princípios do Turismo de Base Comunitária?”. Para alcançarmos resultados, esse trabalho foi construído com o uso de referencial teórico, entrevistas e observação em campo, sendo esse trabalho parte de uma dissertação. A conclusão obtida ao fim da pesquisa aponta que o turismo no Vidigal está pautado em uma lógica mercantil e até mesmo exploratória, diferentemente da sua favela “irmã”, a Rocinha, que é apontada por Freire-Medeiros como tendo a prática do turismo de base comunitária.
A E-Economia e suas Empresas-Plataforma: modus operandi e precarização do mercado de trabalho no setor de turismo
Authors: Moreira Cardoso Ana Claudia , Oliveira Marcela Costa Bifano
Published: December 2020

A economia digital abrange, cada vez mais, dimensões da vida cotidiana e setores da economia. Neste contexto, este artigo teórico se propõe a discutir as diversas plataformas digitais criadas por esta nova configuração da economia, analisando o que há em comum em grande parte delas – a geração de valor baseada na produção de dados pelos usuários –, mas também os elementos que as diferenciam. Neste caso, são analisadas as plataformas de intermediação, da share economy e da gig economy, dando maior destaque, neste segundo grupo, às empresas-plataforma de trabalho por demanda. Posteriormente, o foco recai sobre o setor turístico, onde são identificadas algumas das novas tecnologias e das plataformas digitais que estão sendo criadas e incorporadas pelo setor e seus impactos no mercado de trabalho.  Para tal, utilizamos informações e dados fornecidos por instituições como ETUI, OIT, WTTC, Banco Mundial, LAMFO/UnB, IPEA e IBGE além daquelas contidas nos termos e condições de algumas plataformas. Inicialmente, a hipótese era de que o mercado de trabalho no setor de turismo estaria sofrendo impactos apenas em função da entrada das empresas-plataforma de trabalho por demanda (gig economy) no segmento hoteleiro, como a Brigad. Entretanto, a pesquisa revelou que a situação é muito mais grave. Por um lado, dentre as plataformas da gig economy, além aquelas específicas do setor de hotelaria, também as de entrega (iFood, Uber Eats, Rappi) e de transporte (Uber e 99) estão contribuindo para a precarização dos empregos no setor. Por outro lado, as da share economy, a exemplo do Airbnb, assim como as de intermediação (entre elas a Decolar e a Trivago) também estão impactando de forma negativa o mercado de trabalho seja no que se refere à quantidade de empregos destruídos como a falta de qualidade daqueles poucos que são criados. Assim, podemos dizer que a entrada dessas plataformas no setor está gerando uma onda de precarização laboral num mercado de trabalho já marcado por condições precárias.

Ця стаття продовжує цикл статей, які присвячені особливостям створення та функціонування звукових образів у поетичних текстах. Феномен тиші та його втілення у художній літературі багаторазово привертав увагу дослідників, зокрема філософів, культурологів, філологів. Образ тиші займає важливе місце у творчості Чичибабіна, набуваючи в ній глибокого філософського змісту. Регулярним при створенні образу тиші стає у Чичибабіна прийом персоніфікації, антропоморфізації: його тиша «молитвосклонённая», «безгневная», у неї «нежное касанье». Не дивно, що і кохана стає для поета відчутним втіленням тиші. Мотив, що поєднує кохання з тишею, набуває у ліриці Чичибабіна поширення і розвитку. Все справжнє, з точки зору поета, непоказове, неголосне, тихе, скромне. Тиша осмислюється Чичибабіним як вища форма звучання і у повній відповідності до російської поетичної традиції набуває позитивного значення, асоціюючись у нього з вічністю. Найвищою формою звучання, згідно світогляду поета, стає світло: звук трансформується у тишу і, піднявшись до вершин істини і досконалості, повертається у те початкове Слово, яке згадується у Новому Заповіті і з яким душа ліричного героя Чичибабіна відчуває глибинну спорідненість. Перспективу дослідження автор бачить у характеристиці особливостей представлення образу тиші у творчості інших поетів ХХ століття.

Рецензия на монографию: Радчук О. В. Лингвокогнитивная репрезентация понятия «отсутствие» в русском языке: Монография. Харьков: Юрайт, 2019. 288 с.

Работа О.В. Радчук посвящена когнитивно-лингвистической характеристике базового абстрактного понятия «отсутствие». С точки зрения логики оно относится к кванторам существования, наиболее важным понятиям для человеческого мышления. Понятие «отсутствие» формируется в мыслительной деятельности человека, в процессе отражения действительности в его сознании. Отражение действительности происходит в различных формах, среди которых важную роль, согласно концепции А.А. Потебни, выполняет апперцепция – вторичное осознанное восприятие, подкрепленное опытом носителей языка.

Sanitary control of cutting boards in the kitchen is important to prevent food poisoning. Using ATP and microbiological tests, we investigated the cleaning and 70% alcohol spraying effects of cutting boards for meat and fish. As a result, the ATP value and the number of microbial bacteria decreased after washing the cutting board but decreased more after spraying with 70% alcohol. The ATP value was 100 or less after spraying with 70% alcohol. The number of microbial bacteria decreased after spraying with 70% alcohol. However, not all bacterial eliminated even after spraying with 70% alcohol. If the cutting board left in a moist state at room temperature, microorganisms could grow again.
Special economic zones in Southern Africa: white elephants or latent drivers of growth and employment? The case of Zambia and South Africa
Authors: Phiri Mwanda , Manchishi Shimukunku
Published: December 2020

The successful use of special economic zones as economic tools for export-led industrial development in East Asia propelled a wave of similar initiatives across Africa. In Southern Africa, Zambia and South Africa instituted special economic zones in their respective legal and institutional frameworks in the 2000s as mechanisms for catalysing industrialization and employment creation by means of domestic and foreign investments. Using a case-study approach, we find that special economic zones in the Eastern Cape, South Africa, are largely latent drivers of growth and employment hampered by inadequate infrastructure financing and provision and weak local supplier capabilities. Special economic zones in Lusaka, Zambia, face similar constraints but are further hampered by inadequate business services provision, burdensome regulations and business procedures, a fragmented incentive framework, institutional coordination failures, and a weak design that does not leverage strategic anchor industries for greater agglomeration economies, thus rendering them more of white elephants.

In this article regularities of the creation of laminated metal corrosion-resistant materials with an internal protector obtained by explosion welding are considered. For the first time, a laminated material is considered as a technical system. A systematic approach was used to construct the configuration of layered materials. The functions of individual elements are identified, the nature of the connections is established, and the complexity of the system is assessed. Corrosion tests were carried out, indicators of corrosion resistance were calculated by varying the number of protected and protective layers in comparison with monometallic material. An assessment of the economic efficiency of using laminated metal corrosion-resistant materials with an internal protector is carried out in comparison with monometallic and bimetallic materials.

Authors: ESKİN Bülent , KURT Ahmet
Published: December 2020

Countries in the world have begun to pay more attention to environmental problems in recent years. Because these problems have threatened human life in every aspect and without limit. Climate changes, rising temperatures, melting of glaciers, and the change of natural vegetation are among the threatening environmental issues and many countries act together in the international area on these issues. Protection of ecological balance and natural life, use of renewable energy sources, recycling of wastes, environmentally friendly production methods are strong solutions to be brought to environmental problems. In addition, original academic studies should be conducted to bring solution to the these issues. In this context, bibliometric studies, which is one of the most important reference sources of science policies, come to the fore. In these studies, publications produced by individuals or institutions are analyzed after determining their subject, period and region. In this context, the main purpose of this study is to investigate the master and doctorate theses registered under the title of environment problems in the Thesis Center of the Council of Higher Education between 1978-2018 in line with various parameters by using bibliometric analysis technique. In accordance with this purpose, environmental problems were written in the search section of the web page of the Thesis Center of the Higher Education Council and the master's and doctorate theses were analyzed in detail. 214 master's and doctoral theses have written under the title of urbanization in Turkey by the end of 2018. 36 of these theses are doctoral theses and 178 of them are master's theses. In the scope of the subject, bibliometric studies can be performed on topics such as environment, environmental policy and environmental law in the following years except for the title of environmental problems. In addition, in these subjects comparisons between countries, branches of science and public and private sectors producing publications will be useful for contributing to the literature.
The Role of Myths and Imagination in Cervantes’ Don Quixote and Yaşar Kemal’s The Other Face of the Mountain Trilogy
Authors: ALBAY Neslihan
Published: December 2020

Dreams can play a liberating role to free individuals from repression and feelings of helplessness in the face of strict social rules, customs and mores. It may not be possible to lead a satisfying life under the overwhelming burden of social facts. As individuals want to be alienated or distanced from the painful effects of social experiences and realities, they resort to the hypnotizing influence of dreams that alleviate their individual and social problems. In Miguel de Cervantes Saavedra’s Don Quixote and Yaşar Kemal’s Iron Earth, Copper Sky and The Undying Grass, it is possible to witness how imagination shapes human behaviour and subverts social taboos. The creation of another imaginary world by the characters reflects a desire to escape from the delayed confrontation with unwanted social facts. Characters console themselves and reinforce their hopes through imagination, folk tales and false stories. In all three novels, individual freedom and responsibility outweigh restrictive conventional rules and boundaries in society by transcending time and space. Imagination seems to be the only way of liberation from social and personal depression. Both Yaşar Kemal and Cervantes bear the moral discipline to expose their societies through extravagantly insane characters. Don Quixote is trapped in society and its institutions. He fights against institutionalized society through his imagination, just as Kemal’s villagers desperately create stories and believe in them to avoid their oppressive living conditions under the control of domineering people such as Adil and Sefer in The Undying Grass and Iron Earth, Copper Sky. Both Cervantes and Kemal created characters that live in imaginary worlds and resorted to dreams as an important way to blur the line between reality and imagination. Therefore, the aim of this chapter is to explore the effects of imagination and dreams on human behaviour in Cervantes’ Don Quixote and Kemal’s Iron Earth, Copper Sky and The Undying Grass, which are existentialist works centred on individual and social freedom.
