Published: July 2020

As Industry 4.0 offers significant productivity improvements, its relevance has grown across various organisations. While it captures the attention of both the industry and the academia, very few efforts have been made to streamline useful indicators across stages of its implementation. Such work facilitates the development of strategies that are appropriate for a specific stage of implementation; therefore, it would be significant to a variety of stakeholders. As a result, this paper aims to establish an indicator system for adopting Industry 4.0 within the context of the three stages of the innovation adoption: (i) pre-adoption, (ii) adoption, and (iii) post-adoption. First, a comprehensive review was performed with a search expanding into the literature on innovation and technology adoption. Second, the resulting indicators were filtered for relevance, redundancy, description, and thorough focus discussions. Finally, they were categorised by their stage of adoption. From 469 innovation adoption indicators found in the literature, this work identified a total of 62 indicators relevant for the Industry 4.0 adoption, in which 11, 14, and 37 of them comprised the three stages, respectively. Case studies from two manufacturing firms in the Philippines were reported to demonstrate the applicability of the proposed indicator system. This work pioneers the establishment of an indicator system for the Industry 4.0 adoption and the classification of such indicators into three stages — pre-adoption, adoption, and post-adoption — which would serve as a framework for decision-makers, practitioners, and stakeholders in planning, strategy development, resource allocation, and performance evaluation of the Industry 4.0 adoption.
The Investment Attractiveness of Regions as One of Entrepreneurship Development Factors
Authors: Sikorska-Wolak Izabella , Zawadka Jan , Krzyżanowska Krystyna
Published: July 2020

Subject and purpose of work: The subject of the paper is entrepreneurship development and its determinants, with particular attention to the investment attractiveness of Polish provinces. The purpose of the paper is to identify the level of entrepreneurship development (between 2009 and 2017) and investment attractiveness (between 2009 and 2016) of individual provinces, and to define the correlation between the two features.

Materials and methods: The authors of this paper analysed the literature on the subject and performed desk research using data from reports and studies published by GUS (Statistics Poland), PAPR (Polish Agency for Enterprise Development) and IBnGR (Gdańsk Institute for Market Economics).

Results: In 2017, the number of SMEs* in Poland increased by over 24% in relation to 2009. The results showed a significant inversely proportional correlation between the number of enterprises per 1000 inhabitants and the one-year survival rate for the enterprises. The investment attractiveness of provinces was diverse. The level of investment attractiveness exerted a considerable influence on enterprise development in individual provinces.

Conclusions: The results of the study showed that both the investment attractiveness and entrepreneurship are diverse in individual regions. A significant correlation was found between these two phenomena. Some exceptions to the rule were identified, which can be explained by divergence.
Modern Organization Models as a Means for Realization of Innovative Processes Increasing the Ukrainian Economy Competitiveness
Authors: Popadynets Nazariy , Skrypko Tetyana
Published: July 2020

Subject and purpose of work: Ukraine’s dynamics by the competitiveness indicators shows the low macroeconomic status and insufficient innovative business climate, yet it doesn’t contradict the opportunities of economic growth. The research is devoted to adaptation of theoretical and applied organizational models of economy growth on the grounds of innovative entrepreneurship development, activation of public-private partnership and functioning of crowdsourcing virtual configuration of commercial and non-commercial social entities. The major objective of the paper is to examine the evolution of organizational models, to determine the tendencies of organizational renovation of economic system based on scientific and technological progress and to outline the directions of improving the efficiency of organizational-institutional transformations in Ukrainian economy.

Materials and methods: The research is based on universal methods of formal logic and scientific abstraction, basics of innovation science, investment science and institutional economics, systemic, structural-functional and synergetic approaches as well as information sources of World Economic Forum.

Results: The authors’ hypothesis about the correspondence of organizational models to the stages of society’s innovative development is verified. General positioning of Ukrainian economic system in investment-driven classifications is confirmed, аnd activation of mass collaboration model is emphasized in the sector of innovative entrepreneurship.

Conclusions: In order to increase the efficiency of organizational-institutional transformations, the concept of bureaucracy-type administrative management is suggested to be reoriented towards the use of adhocratic model with the elements of virtual communication and total digitalization. Social effect of mass collaboration model is determined to be the stimulator of institutional changes in macroeconomic development.
Degree of Concentration of the Banking Sector in B&H and the Impact on the Prices of Banking Products
Authors: Bojat Milica , Rebić Mladen
Published: July 2020

This paper tends to examine the level of concentration of the banking sector in Bosnia and Herzegovina. The main objective of the paper is to measure the level of concentration and to investigate how the concentration and type of market structure affect the prices of banking products. By monitoring the movement of key indicators, it provides an insight into the state of the B&H banking sector. By using the appropriate index (HHI, CR3), the movement of concentration levels and the shape of the market structure that prevailed in the banking market over a period of time were determined. The results show that there is a moderate concentration in the B&H banking sector, which includes monopolistic competition as a form of market structure. This means that the equilibrium level of production is achieved at a lower volume of production, at higher prices for banking products (above marginal costs), thereby reducing consumer surplus relative to a perfectly competitive market
Attitudes of Children and Youth on the Serbian Business Sector
Authors: Krstić Nataša , Piper Danica Čigoja
Published: July 2020

Apart from the increasing attention paid to the role of business in society, with an expanded awareness of the link between the business sector and human rights, over the last decade, there has been a trend of trying to understand the relative impact of businesses on children’s rights. After the promotion of the Children’s Rights and Business Principles in 2012, the impact of the business sector began to be viewed through the diversity of its possible effects on children in the workplace, the marketplace, in the community or in relation to environmental protection. A quantitative survey of children and young people in Serbia conducted via UNICEF’s U-Report platform aiming to test the hypothesis“Are children and youth in Serbia aware of the impact that the business sector has on them?” identified their attitudes that companies can help them in their future development paths, that the greatest area of impact on children’s rights comes from the workplace – by providing decent work for young workers and parents and making future jobs more accessible to young people through education and training programmes.At the same time, the expectation of children and youth in Serbia for greater participation of companies in supporting and realising the rights of children in society was emphasised.
Hormonal Mechanisms in Atherosclerosis
Authors: Dobrescu Mariana , Păun Diana , Grigorie Daniel , Poiană Cătălina
Published: July 2020

Cardiovascular disease is a complex process that includes genetic, inflammatory and endocrine components. During the last decades, much emphasis has been given to cholesterol and lipids as the primary determinants in cardiovascular disease. However, many endocrine and biochemical factors are involved in the atherosclerosis process as well, both systemically and vascular. Multiple obvious data suggest that hormones are responsible for subtle cardiovascular changes long before the development of overt atherosclerotic. Much research remains to be done regarding the interaction between endocrine systems and their role in atherogenesis.
Analysis of the Connections Between Law and Morals, Between Customs and Contemporaneity
Authors: Iovan Marțian
Published: July 2020

This paper analyses the concepts of three great Romanian thinkers –theoreticians and philosophers of law – on the relations between law, morals and manners in order to discover, based on their idea filiation in the juridical Romanian culture, the differences of method and contents between them, to identify the practical implication in the field of performing the justice and law-making. Being trained and positioned in the core of the European juridical culture of their time, they reviewed the relations between law and morals, in a rationalist and humanist way, substantiating the need for the law to follow morals, the ethical principles both historically, and practically, the law-making being comprised as well. Thus, they leave room to the expression of human’s basic rights and freedoms in a democratic judicial order, while the rules of law subordinating the morals and manner proved to be widely open to totalitarianism.
Legal Regalements of E-Signature
Authors: Edisherashvili Tea
Published: July 2020

The development of informative technologies, including that of the Internet, has significantly changed the human’s life. The largest portion of civil turnover has been encompassed by e-commerce. This latter is being executed through e-contracts. The e-contract from the doctrinal point of view is considered as dealt and the existence of e-signature is an essential component of its authentication, which in its turn determines the issue of existence-absence of written form. The present article is related to the issues of legal status, technical safety and reliable environment of application of e-signature. The necessity of applying the legal instrument was conditioned by the necessity of gradual disappearance of paper-based operations’ execution practice. The application of e-document turnover is justified only in case if the authentication of the document and the signature placed on it has been followed and all this has been acknowledged by the third party. Despite the various models of e-signature, for all of them, it is important to have a reliable and safe environment, for guaranteeing the safety and signer’s identity. The article shows the issues related to legal governing of e-signature according to the legislation of Georgia, also Russian Federation, Continental Europe, Common Court member states, as well as directives and guidelines developed by international organizations.

Main Events List/Main Incidents List Development Process for Computer Assisted Exercises
Authors: Neagoe Zinca Diana-Ioana , Bârsan Ghiță
Published: July 2020

In order to train commanders in the decision making process we cannot rely only on simulation systems. It takes more than war-gaming to be able to train higher-headquarters and a proven solution to achieve that is by using computer assisted exercises (CAX). The higher the headquarters that needs to be trained, the more complicated the systems’ architecture becomes, for both functional area services and simulation systems together with their auxiliary tools. It takes subject matter experts in different domains and up to 18 months to plan a computer assisted exercise. Every stage of the exercise planning process involves using different systems and building their databases. In order for the commanders to be successfully trained in the decision making process, they need to face operational dilemmas. The Main Events List/Main Incidents List (MEL/MIL) planning team’s job during the exercise planning phase is to develop the major events, incidents and injects which will trigger the operational dilemmas and will force the commanders to make decisions in dynamic and fast-paced environments. The MEL/MIL plays a key role in ensuring a successful execution phase of an exercise and this study explains in detail the complex 8 month process of building the MEL/MIL database.
Preparation of a solid product with high water content and water retention properties
Authors: Cvijić Marko , Golob Janvit
Published: July 2020

This work presents the development of a solid product with a high water content (99.08%) and water retention properties. Water was chosen as a potential carrier of a volatile active substance and water retaining properties of material were studied at a temperatures and relative air humidity values with the support of the theory of drying. The study first confirmed the role of Gibbs’ phase rule in the research of solid-gas phase equilibrium, and second presented drying kinetics developed from Fick’s second law and expressed with the first term of the Fourier equation. Solutions of equations for phase equilibrium and mass transfer enabled the calculation of Luikov’s parameters, which are important for equilibrium relations and for the diffusivity of water in a solid for mass transfer prediction. The obtained thermodynamic and kinetic parameters enabled product characterisation that may be important for the prediction of retention times.

Published: July 2020

The electrocatalytic reduction of carbon dioxide into valued chemicals such as formic acid has the most promising potential in applying renewable energy for useful materials and mitigating the greenhouse effect. However, the studies still focus on developing catalysts with low price and high catalytic properties. In this study, nitrogen atoms were decorated into carbon structure by a unique ultrasonic method, then the nitrogen-doped carbon material was applied as catalyst in CO2 reduction, it exhibited excellent electrochemical activity, 4 times higher than the normal method. The improved activity should be attributed to the interaction between nitrogen and carbon atoms through analysis.
Social Constructivism as Forecasting Matrix. Collective Habitus in International Relations
Authors: Chwedczuk-Szulc Karol , Polus Andrzej
Published: July 2020

Social constructivism is not among the most popular theoretical approaches used in forecasting in International Relations. The article argues that constructivism suffers from the same limitations as any other paradigm in IR, therefore, there is no reason to exclude this theory from forecasting effort. In this paper, social constructivism is perceived to offer a new conceptual framework for sound and robust projections of the future. The core of our concept is constituted by the term of collective habitus. Habitus is a relatively stable, yet mutable social structure that can enable deliberations about future. It is based on a long-term history study programme of the School of Annales, as we identify long lasting habits-like patterns of behaviours among IR actors.
Should I Stay or Should I Vote? „Beto an Underdog” and his Mobilization Campaign
Authors: Tomaszewski Norbert
Published: July 2020

Beto O’Rourke’s 2018 Senate bid resulted in one of the most interesting political campaigns of past decade. Even though he was less experienced than his rival and ran as an underdog, O’Rourke managed to attract thousands of donors and almost made a political upset, by losing to Ted Cruz by a small margin. The article focuses on his road to nationwide recognition and the use of new media, which allowed him to reach out to the voters.
Value-Based Ideas or Material Interests? An Explanation of Polish Governmental Preference Formation towards Eurozone Accession
Authors: Novak Roman
Published: July 2020

Why did Poland not join the Eurozone despite being integrated economically and dependent on investments and trade with existing Eurozone countries? The reluctance of its government seems puzzling taking into consideration Polish economic exposure to Eurozone countries as well as its commitment to switch to the euro stemming from EU treaties. The Polish governmental position on Eurozone accession demonstrates that monetary integration is not only an economic and legal issue, but it also results from political decisions of individual governments. This paper argues that a complementary understanding of the position of the Polish government on Eurozone accession is possible by looking at domestic ideas and interests. For this aim, the societal approach to governmental preference formation is employed. It focuses on the influence of domestic ideas (value-based collective expectations of voters) and interests (cost-benefit calculations of lobby groups) on governmental positions. In applying the societal approach, this paper has two goals: first, to show that the Polish governments’ reluctance to join the Eurozone stems from domestic societal pressures (value-based ideas and material interests) and, second, to specify the conditions for either ideas’ or interests’ individual bearing on the government’s preference.
Appearance and Distribution of Tissue Remodellation Factors in the Hard Tissue of Patients Affected by Cleft Lip Palate
Authors: Buile Dace , Pilmane Māra , Akota Ilze
Published: July 2020

Bone repair after surgical intervention on cleft lip palate (CLP) depends on the coordinated action of multiple tissue regeneration factors. We determined the relative number and appearance of tissue factors: matrix metalloproteinase-2 (MMP-2), tissue inhibitor of metalloproteinase-2 (TIMP-2), bone morphogenetic protein 2/4 (BMP 2/4), transforming growth factor beta (TGF-ß), Wnt3a protein (Wnt3a), Runt-related transcription factor 2 (Runx2), basic fibroblast growth factor (bFGF) and osteoprotegerin in hard tissue of CLP patients during first time surgical intervention. Fourty-three CLP patients with 24 bone and 36 cartilage samples were involved. Immunohistochemistry was used to assess the levels of tissue factors and the semi-quantitative census method was used for quantification of immunological structures. The increased amount of MMP-2 and bFGF positive cells was detected in the CLP group in cartilage and bone (p < 0.05), compared to the controls. A statistically significant (p = 0.012) increased amount of BMP 2/4 positive cells was found in cartilage of CLP patients, in comparison to the control group. Increased appearance of MMP-2, bFGF in hard tissue of the CLP patients indicates the predominance of tissue degradation. Increased number of BMP2/4 positive chondrocytes suggests improved cartilage growth and better regeneration in CLP patients.
Slovakia as a Safe Country – The Perspective of the Slovak Community Members of Vojvodina
Authors: Marušiak Juraj , Zlatanović Sanja
Published: July 2020

This article explores the current migration of the Slovak community members of Serbia to Slovakia, focusing on their perception of safety and risk, in the period since 1990 when the post-Communist transition began both in Serbia and Slovakia. The authors attempt to analyse how the members of the given community, who migrated to Slovakia during the reference period, perceive Slovakia today from the point of view of their safety, understood as the search for freedom from threats. They focus on individual safety factors (life, health, status, wealth and freedom). After 1990, Slovakia became not only a country left by migrants, but also a country of destination for migrants. One such migrant group is the members of Slovak communities abroad, in particular Serbia, Romania and Ukraine. The first wave of migration of Slovaks from Serbia took place in the early 1990s in connection with the violent ethnic conflicts in former Yugoslavia, and the next one as a result of the global financial crisis in 2008, which intensified after 2015. The main push factors of the migration of Vojvodina Slovaks to Slovakia in the 1990s included attempts to avoid mobilisation and participation in combat operations; after 2008, the key role was played primarily by material issues which they perceived as an existential threat to themselves and to their families. The main pull factor in favour of choosing Slovakia comprise of the relatively small administrative barriers and linguistic proximity. While our interlocutors regarded their concerns about the impacts of the 1990s war conflicts as short-term threats, they perceived the social impacts of the economic transition and uncontrolled global financial crisis after 2008 as long-term or even permanent threats. In this context, they consider Slovakia a safe country. The article is based on extensive multi-sited fieldwork – in-depth interviews with the members of the community – and on other available sources (legal documents, statistical data, media, etc.).
“Fucking Koreans!”: Sexual Relations and Immigration in the Philippines
Authors: Pack Sam
Published: July 2020

Drawn by the tropical weather and pristine beaches, significantly lower cost of living, and proximity, South Koreans are now the top tourists in the Philippines. Besides the short-term tourists, more than 100,000 South Koreans have chosen to permanently reside in the Philippines, making them the largest immigrant population in the country. Recently, a tenuous relationship between these two groups has emerged marked by mutual antipathy. I have overheard many Koreans describe Filipinos as impoverished, lazy, and socially backwards. They appear to have internalized a racial hierarchy whereby they perceive their darker-skinned Asian counterparts as ranking lower on the pigmentocracy scale. Conversely, Filipinos complain incessantly that Korean immigrants and visitors alike are arrogant, rude, and provincial, refusing to learn Tagalog or appreciate, much less respect, local customs. The exclamation, “Fucking Koreans!” has become a familiar refrain by Filipinos in response to being treated as second-class citizens in their own country. This utterance also has a secondary meaning as the one area where Koreans and Filipinos commonly do interact is in the form of sexual relationships.

Thesis Writing Model of Art Practice
Authors: Moerdisuroso Indro , Kherid Zaitun Y.A.
Published: July 2020

ABSTRACT The result of this study is contributed to improving the academic thinking of art practice students, especially in the writing of the undergraduate thesis. The problem is about a system of academic thinking as reflected in the thesis guidebook. Students' academic thinking in thesis writing is guided by a manual book published by a local institution. The case in this study is the thesis guidebook of art practice in an art study program. In this book has no explicit explanation on method and analysis aspects. Whereas both of these aspects are precisely the essence of academic thinking, that is research-based thinking. This fact encourages a study of thesis writing model of art practice, particularly on methods and analysis aspects. This study implements a Research and Development (R&D) approach and mixed methods. The model will propose Teikmanis' typology of art-related research, such as practice-led research, research-led practice, and artistic research. It also adapted Barrett's structure of art education, which consisted of conceptual, operational and synthesis aspects. The conclusion of the study showed that the participants were able to arrange a thesis based on this model. Model Penulisan Tesis Praktik Seni ABSTRAK Hasil penelitian ini dikontribusikan untuk meningkatkan pemikiran akademik mahasiswa praktik seni, khususnya dalam penulisan skripsi. Masalahnya adalah tentang berpikir akademis sebagaimana tercermin dalam pedoman skripsi. Pemikiran akademis dalam penulisan skripsi dipandu oleh pedoman penulisan yang diterbitkan oleh institusi terkait. Kasus dalam penelitian ini adalah suatu pedoman skripsi praktik seni dalam suatu program studi seni rupa. Dalam buku ini tidak ada penjelasan eksplisit tentang aspek metode dan analisis. Padahal kedua aspek ini justru merupakan inti dari pemikiran akademis, yaitu pemikiran berbasis penelitian. Fakta ini mendorong studi model penulisan skripsi praktik seni, terutama dalam aspek metode dan analisis. Studi ini menerapkan pendekatan Penelitian dan Pengembangan (R&D) dengan metode campuran. Model ini mengusulkan tipologi penelitian seni Teikmanis, seperti practiceled research, research-led practice, dan artistic research. Selain itu juga mengadaptasi struktur pendidikan seni Barrett, yang terdiri dari aspek konseptual, operasional, dan sintesis. Kesimpulan dari penelitian ini menunjukkan bahwa para partisipan dapat menyusun skripsi berdasarkan model ini.
Producción topológica de la domesticidad

Published: July 2020

El objetivo de esta investigación es comprender los espacios producidos en la domesticidad, teniendo en consideración los roles de género como una estructura determinante en la distribución y ejecución de las tareas domésticas de los sujetos, las que son base de la organización del núcleo familiar en la construcción de sus micro geografías.Mediante el uso de metodología cualitativa, esta investigación vinculada a la geografía de género ha buscado analizar de forma situada cada uno de los casos consultados, propiciando así el surgimiento de categorías y experiencias espaciales de cada una de ellas, siendo estudiados cuatro núcleos familiares de dos grupos socioeconómicos distintos (medio y alto) con distintas dinámicas de ausencia en el hogar (alta y baja). Los resultados del estudio muestran la desigualdad entre mujeres y hombres en el entorno familiar a la hora de la participación en tareas domésticas y cuidado de los infantes, así como también las limitaciones espaciales que tienen las y los sujetos a la hora del ocio y el desarrollo integral de los niños. Estas limitaciones son superadas solo a través de redes personales que generan las familias, dejando en evidencia limitaciones económicas y la activación de redes personales como la única posibilidad de apoyo.
Movilidad y accesibilidad a la salud
Authors: Lazo Alejandra , Carreño-Calderón Alejandra , Astorga Sofía
Published: July 2020

El estudio de la influencia que tienen las condiciones geográficas y la movilidad como barreras de acceso a la salud se ha focalizado principalmente en áreas urbanas y suburbanas. En este escenario, el objetivo de esta revisión es presentar una sistematización de las investigaciones existentes sobre movilidad y accesibilidad a la salud en territorios archipelágicos e isleños.  Para ello, durante el año 2019 se realizó una revisión de literatura usando ISI Web of Science. Específicamente, fueron revisados 54 artículos que abordaban aspectos relacionados con la movilidad, como son la distancia, la organización geográfica de los sistemas de salud, las experiencias de viaje y los sistemas de transporte en estos territorios. Los resultados que emergen de la búsqueda se agruparon en cuatro categorías: 1) artículos relacionados con las disparidades en el acceso a prestaciones médicas específicas; 2) artículos de discusión metodológica sobre la medición de la accesibilidad a salud; 3) estudios de caso sobre la movilidad del personal de salud y 4) artículos sobre sistemas de transporte y movilidad cotidiana de usuarios en sus viajes hacia la salud. Finalmente, se observa que la mayor parte de los estudios identificados mantienen un enfoque tradicional que pone a la distancia y la distribución de los servicios médicos al centro del debate. Sin embargo, se evidencia un escaso interés por abordar la accesibilidad desde el punto de vista de la movilidad, incorporando en algunos casos dimensiones subjetivas del viaje, así como la especificidad del territorio como variables que determinan el acceso a salud.  En este sentido, constatamos que la movilidad por motivos de salud en archipiélagos e islas ha sido escasamente problematizada.

Published: July 2020

O presente estudo analisou as características sócio produtivas em unidades de agroindústrias familiares do município de Guaraniaçu – PR, identificando as principais características relacionadas a sua composição produtiva e tamanho de área, tamanho das famílias, ocupação da mão de obra e suas características sociais. Caracterizou-se como uma pesquisa descritiva das informações extraídas do questionário estruturado, aplicado por meio de entrevistas durante visitas às propriedades rurais com atividade de agroindústria durante o mês de julho de 2018, investigando 28 unidades. Identificou-se que possuem em grande maioria estrutura administrativa familiar, são assistidas por alguma forma de Assistência Técnica e Extensão Rural (ATER), basicamente utilizam mão de obra familiar, baixa representatividade de empreendimentos novos e estão instaladas em pequenas propriedades rurais. Encontrou-se predominância de dois a quatro membros residentes, não se podendo vincular a totalidade dos membros com mão de obra disponível, o que compromete a sucessão familiar. A mão de obra dos membros das unidades estudadas está relacionada à atividade da agroindústria e agricultura, constatando-se pluriatividade também pelas atividades urbanas encontradas nestas unidades. Sugere-se para futuros estudos uma análise sobre o tempo de vida destes empreendimentos e quais os fatores que contribuem para o seu maior ou menor tempo de funcionamento bem como a questão de sucessão familiar.
DISPOSITIVOS HÍBRIDOS: FERRAMENTAS OU INTERMEDIÁRIOS NO PROCESSO DE CONFIGURAÇÃO DE MERCADOS?
Authors: Acosta Daniela Caldas , Favero Marcela Bortotti , Guarniere Fernanda
Published: July 2020

O presente ensaio tem como objetivo apresentar uma classificação para a ação do dispositivo na configuração de mercados. Utilizando como plano teórico a perspectiva construtivista de estudos de mercados, buscou-se avançar teoricamente a classificação dos dispositivos que atuam na formatação de mercados. Para desenvolvimento deste trabalho, utilizou-se a pesquisa bibliográfica analisando a descrição da atuação de diferentes dispositivos apresentadas em estudos científicos. Sugere-se a classificação do dispositivo de acordo com a autonomia que o mesmo tem ao longo da ação de configuração do mercado, sendo que este pode ser considerado como um intermediário ou como uma ferramenta. O dispositivo assume papel do ator intermediário quando o mesmo tem capacidade de agência e domínio da ação, conseguindo dessa forma tomar decisões e modelar o mercado sem um filtro de um ator humano.

O setor de construção civil está entre um dos mais representativos no cenário econômico do país, sendo um mercado em forte expansão. Contudo, junto com esse crescimento, está atrelada a geração de resíduos sólidos, que causam grandes impactos ao meio ambiente quando descartados de forma incorreta. Destarte, o objetivo deste estudo foi de analisar a percepção ambiental das empresas filiadas ao Sindicato da Construção Civil do Oeste do Paraná. A pesquisa foi quantitativa com aplicação de formulário de coleta de dados. A análise estatística dos dados iniciou com uma análise unidimensional de todas as questões obtidas pelo formulário de coleta de dados. Em seguida, algumas variáveis foram analisadas de forma bidimensional com a aplicação do teste de independência para verificar a existência de associação estatística significativa entre os cruzamentos. Como resultados verificou-se que a maioria dos gestores das empresas que estão preocupados com as questões ambientais, adota o Plano de Gerenciamento de Resíduos e procuram utilizar materiais que possam ser reciclados ou reutilizados em outras obras.
“As guerras linguísticas”: afiliações e rupturas na ciência da linguagem do século XX
Authors: De Oliveira Batista Ronaldo , Araújo Carlos Henrique Teixeira de
Published: July 2020

Por meio de fundamentos teóricos e procedimentos metodológicos da Historiografia da Linguística, Cristina Altman apresenta uma abordagem da história da linguística a partir de um ponto de vista diferenciado: compreender algumas etapas do desenvolvimento de teorias estruturalistas (entre os anos 1920-1950) a partir do contato entre pesquisadores norte-americanos e europeus. Esse contato não se deu de forma pacífica e permite que se observe que a ciência é prática humana, permeada por associações e conflitos. Destacam-se aspectos teóricos e sociais do diálogo entre pesquisadores, envolvidos em comunidades em polarização, com referência também à recepção brasileira diante dos polos opostos que constituíram a assim chamada guerra fria estruturalista.
The Iron Hatchet of Saka Period from Burial Site Jal-Aryk II (Ketmen-Tyube Valley, Western Tien Shan)
Authors: Ivanov Sergei S.
Published: July 2020

The article is devoted to the analysis of the iron battle hatchet from mound 2 of the Jal-Aryk II burial site in Ketmen-Tyube valley in the western part of Tien Shan.
Purpose. Battle hatchets are a rare category of weapons of Saka culture in the Tien Shan region. Therefore, the publication of one of the first finds of this type of weapon, which was made in the 1960s, is considered important.
Results. The combat hatchet has a straight pin, massive hammered butt and closed shaft-hole for the wooden handle. The combat hatchet also has iron capping, protecting the end of the handle. The features of the funeral inventory from the burial where the hatchet was found and based on analogies from Central Asia and Altai, and dates back to the late 5th – early 4th centuries BC. The closest parallels to it can be found in Saka burials in Semirechie and in related materials of the Kamen (Kamenskaya) culture in the Forest-Steppe of Altai.
Conclusion. The investigated combat hatchet is one of the earliest examples of iron arms of the Saka culture in the Tien Shan region. In addition, we can conclude that this type of weapon appeared in their culture as a result of very close cultural contacts with the ancient population of the Forest-Steppe of Altai. However it was ultimately concluded that the combat hatchet from the Ketmen-Tyube valley had local origin and reflects the independent line of development of this type of weapon in the local Saka culture, based on samples from the Forest-Steppe of Altai.

The pipeline of antibiotics has been for decades on an alarmingly low level. Considering the steadily emerging antibiotic resistance, novel tools are needed for early and easy identification of effective anti-infective compounds. In Gram-negative bacteria, the uptake of anti-infectives is especially limited. We here present a surprisingly simple in vitro model of the Gram-negative bacterial envelope, based on 20% (w/v) potato starch gel, printed on polycarbonate 96-well filter membranes. Rapid permeability measurements across this polysaccharide hydrogel allowed to correctly predict either high or low accumulation for all 16 tested anti-infectives in living E. coli. Freeze-fracture TEM supports that the macromolecular network structure of the starch hydrogel may represent a useful surrogate of the Gram-negative bacterial envelope. Machine learning by random forest analysis of in vitro data revealed minimum projection area, molecular mass, and rigidity as the most critical physicochemical parameters for hydrogel permeability, in agreement with reported structural features needed for uptake into Gram-negative bacteria. Correlating our data set of 27 antibiotics from different structural classes to reported MIC values of seven clinically relevant pathogens allowed to distinguish active from non-active compounds based on their low in vitro permeability and in particular to identify poorly permeable antimicrobial candidates before testing them on living bacteria.
Controlling Singlet Fission with Coordination Chemistry-Induced Assembly of Dipyridyl Pyrrole Bipentacenes

Published: July 2020

Singlet fission has the potential to surpass current efficiency limits in next-generation photovoltaics and to find use in quantum information science. Despite the demonstration of singlet fission in various materials, there is still a great need for fundamental design principles that allow for tuning of photophysical parameters, including the rate of fission and triplet lifetimes. Here we describe the synthesis and photophysical characterization of a novel bipentacene dipyridyl pyrrole (HDPP-Pent) and its Li- and K-coordinated derivatives. HDPP-Pent undergoes singlet fission at roughly 50% efficiency (τSF = 730 ps), whereas coordination in the Li complex induces significant structural changes to generate a dimer, resulting in a 5-fold rate increase (τSF = 140 ps) and near fully efficient singlet fission with virtually no sacrifice in triplet lifetime. We thus illustrate novel design principles to produce favorable singlet fission properties, wherein through-space control can be achieved via coordination chemistry-induced multi-pentacene assembly.

Biomimetic total synthesis has played a pivotal role in the development of synthetic organic chemistry. In particular, efforts aimed at mimicking the head-to-tail (HT) cation–π cyclization cascades invoked in terpene biosynthesis, such as those catalyzed by type-II cyclases, have led to a multitude of new synthetic methods, chemical concepts, and total syntheses over the past century. Conversely, synthetic methodology that mimics tail-to-head (TH) cation–π cyclization cascades, mediated by Mg2+ type-I terpene cyclases, remains elusive in organic synthesis, despite key roles in the biosynthesis of privileged therapeutic molecules such as taxol and artemesinin. Here we report that Li+/weakly-coordinating anion (WCA) salts catalyze the TH polycyclization of linaloyl fluoride, leading to high-yielding mixtures of polycyclic terpene natural products including cedrenes, cadinadiene, epizonarene, and 𝛿-selinene. The examples reported herein are the first small molecule-catalyzed TH polycyclization reactions enabling the shortest (formal) total synthesis of (±)-artemisinin. Moreover we apply this strategy to the diterpene geranyllinaloyl fluoride, resulting in a two-step total synthesis of the tricyclic core of the gersemiols (named here as α-gersemiene), a recently discovered class of marine diterpenoid natural products.

Mulliken-Dipole Population Analysis

Published: July 2020

Atomic charge is one of the most important concepts in Chemistry. Mulliken population analysis is historically the most important method to calculate atomic charges and is still widely used. One basic hypothesis of this method is the half-and-half partition of the overlap populations, Q(μ, v), into equal charges in orbitals μ and v. This partition preserves the monopole moment of the overlap density but, other than that, is arbitrary. In this work we derive a new population analysis (which we designate Mulliken-Dipole population analysis) based on the conservation of both the monopole moment and the dipole moment along the bond direction. Test calculations show that the Mulliken-Dipole atomic charges are in accord to the chemical intuition; also they are very different from the Mulliken ones, being quite similar to the Hirshfeld atomic charges. Mulliken-Dipole atomic charges are conceptually appealing and very easy to calculate. In a further step, we also show how this Mulliken-Dipole population analysis can be used to derive atomic charges for atomistic simulations that reproduce the total dipole moment of the molecule, yielding at the same time a good description of the local charges and dipole moments for the molecular fragments.
