Authors: Alves Wellington , Silva Ângela , Rodrigues Helena Sofia 
Published: December 2022

Abstract

Background: Circular Economy has been considered one of the most powerful principles of modern society. The concerns about increasing resource consumption have forced governments and companies to look at the circular models as a hedge against resource scarcity and an engine for innovation and growth.

Objectives: This research aims to bring together the Circular Economy and the consumer’s perspective to perceive the impact of its choices on CE initiatives.

Methods/Approach: A survey was conducted considering the consumer’s engagement with the circular economy concepts.

Results: The results pointed out the awareness and willingness of consumers for the transition from the linear to the circular production model, providing an added value to consumers for reducing environmental impacts.

Conclusions: Consumers’ behaviour can have a forefront role in building a guide with best practices to be considered by companies, designers, and consumers on implementing initiatives in the field of Circular Economy.

Authors: Pintado Eduardo , de Oliveira Lia Coelho , Garcia Jorge Esparteiro 
Published: December 2022

Abstract

Background: E-commerce has emerged as a good response to the pandemic of COVID-19. However, the costs of providing a service, which includes a driver and a vehicle, in a regular vehicle that can transport goods that need positive cold (0° to 5°C) are very high.

Objectives: This paper aims to investigate how a big Portuguese retailer company can reduce its dependence on refrigerated vehicles, simplifying operations and reducing the costs of transporting positive and negative cold food.

Methods/Approach: This research was carried out in a food retailer Portuguese company, more precisely in a Dark Store dedicated to the online channel. The study was developed based on the AS-IS/TO-BE process analysis methodology, starting with the analysis of the current situation, giving rise to the so-called AS-IS model.

Results: It was possible to reduce costs associated with transporting positive cold goods. As a result, there are 30% fewer costs associated with order transportation. With an additional 10% in space optimization with the gain of space within the galley of each vehicle.

Conclusions: The costs of transporting positive and negative cold foods were decreased, and substituting vehicles with room temperature transport reduced the need for refrigerated vehicles.

Authors: Jošić Hrvoje , Žmuk Berislav 
Published: December 2022

Abstract

Background: This paper presents a machine learning approach to forecast Croatia’s international bilateral trade.

Objectives: The goal of this paper is to evaluate the performance of machine learning algorithms in predicting international bilateral trade flows related to imports and exports in the case of Croatia.

Methods/Approach: The dataset on Croatian bilateral trade with over 180 countries worldwide from 2001 to 2019 is assembled using main variables from the gravity trade model. To forecast values of Croatian bilateral exports and imports for a horizon of one year (the year 2020), machine learning algorithms (Gaussian processes, Linear regression, and Multilayer perceptron) have been used. Each forecasting algorithm is evaluated by calculating mean absolute percentage errors (MAPE).

Results: It was found that machine learning algorithms have a very good predicting ability in forecasting Croatian bilateral trade, with neural network Multilayer perceptron having the best performance among the other machine learning algorithms.

Conclusions Main findings from this paper can be important for economic policymakers and other subjects in this field of research. Timely information about the changes in trends and projections of future trade flows can significantly affect decision-making related to international bilateral trade flows.
Financial development and economic growth in Botswana: New evidence from disaggregated data
Authors: Musakwa Mercy Tsitsi , Odhiambo Nicholas Mbaya 
Published: December 2022

Abstract
In this study, the causal relationship between financial development and economic growth in Botswana is re-examined using disaggregated data from 1980 to 2020 on financial development. The importance of financial development and economic growth in achieving Sustainable Development Goals (SDGs) cannot be overemphasised. The study used the Autoregressive Distributed Lag (ARDL) approach to cointegration and the ECM-based Granger causality test to examine this linkage. Financial development is measured at an aggregate level by the Financial Development Index (FDI) and at a disaggregate level by the Financial Institution Index (FII) and Financial Market Index (FMI) from the International Monetary Fund (IMF) financial development index database. The study failed to find any causality between financial development and economic growth during the study period. The results apply, irrespective of proxy used to measure the level of financial development and the time frame. This finding points to the importance for Botswana to continue with the Vision 2036 and the National Development Plans that focus, among other goals, on economic growth, to realise an increase in gross fixed capital formation and financial development.
Conceptual understanding of linear regression among economics students at the university center of Tipaza, Algeria
Authors: Idris Djouahra 
Published: December 2022

AbstractSolving problems related to econometrics requires a good knowledge of regression analysis concepts. The objective of this study is to evaluate students’ difficulties resulting from the lack of knowledge of regression analysis concepts among economics students enrolled in the Master’s cycle at the institute of economics at the university center of Tipaza (Algeria). In order to analyze students’ answers, a typical correction was prepared based on professors’ answers to this questionnaire. The procedure consists of comparing students’ key answers with their corresponding typical answers to see how near or far it is from the right answer. In order to see whether the difficulties are originated from the same students, we analyzed the association between answers based on Multiple Correspondence Analysis (MCA) method. The principal results showed that difficulties resulting from the lack of knowledge of regression analysis concepts were prevalent among students. Their main causes were strongly related to misunderstanding, misconceptions and confusions. MCA analysis indicated that students can be categorized according to their answers into four groups: a very weak group, a weak group, an average group and a good group. We concluded that the difficulty of solving problems in the context of linear regression among students is the result of a lack of knowledge of regression concepts coupled with the inability to explain them.
Study on the Properties of Plain Cotton Fabric Strength in a Natural Environment for Upcycling Textiles
Authors: Yang Chen , Song Ha-young 
Published: December 2022

Abstract
The research primarily aimed to observe the fibre structure of cotton stock fabric through a scanning electron microscope (SEM). Then, textile durability, appearance, and comfort were tested in line with the international standards organization's (ISO) guidelines. For this, the storage time and a series of performance indicators including breaking strength, tensile strength, colour fastness to soap washing, colour fastness to dry rubbing as well as wet rubbing were evaluated, tested and analysed. Finally, through statistically analysing the data obtained, the limit value of the physical performance index and storage time of the fabrics were acquired, and further forming of the upcycling standards of cotton stock fabric.
In this study, two cotton fabrics were selected, namely, natural-coloured cotton fabric (width 162 cm, weight 120.8 g/dm2, density 281 / 10 cm × 252 / 10 cm) and black-coloured cotton fabric (width 157 cm, weight 136.1 g/dm2, density 482 / 10 cm × 210 / 10 cm). The research experiments showed that when cotton stock fabrics were stored in a natural environment (temperature 20°C, humidity 65%), as the storage time increased, the surface yarns gradually began to loosen, with some loose yarns appearing on the surface. After 90 days the loosening intensified, and after 270 days the yarn looseness was obvious. After 330 days, a break in the fibrous structure on the surface of the natural-coloured cotton stock fabric could be observed. When natural-coloured cotton stock fabric was stored in a natural environment for 360 days, it lost 4.4% of its warp-breaking strength and 12.56% of its weft-breaking strength. For black cotton stock fabric, the figures were 5.66% and 20.54% for the warp-breaking and weft-breaking strength, respectively.

Published: December 2022

Abstract
The paper describes the results of research on consumer awareness and attitudes in the field of the ecology and labelling of packaging products. The research was divided into two parts. The first one was related to the perception of the respondents regarding ecology, while the second one was related to the classification of the cosmetics packaging products presented. The results obtained were analysed statistically. The correlation analysis performed showed the existence of a relationship between the variables selected (consumer attitudes). Strong correlations were noticed. The research showed that consumers equate labelling to the properties of products and packaging. The labelling of packaging and products can be ambiguous, which results in a problem with classifying waste to the appropriate segregation and collection system.

International and Domestic Factors Shaping Kosovo’s Euro-Atlantic Integration
Authors: Dolan Chris J. , Hajrullahu Arben 
Published: December 2022

Abstract
This study examines the complex and dynamic relationship between Kosovo and NATO. It argues that Kosovo’s prospects for NATO membership are shaped by an array of contradictory and often confusing international and domestic political forces. It draws on theoretical sources, media reports, and descriptive statistical data to the factors shaping expectations for NATO membership. The study relies on theories and concepts from the established and evolving literature on alliance formation and expansion to explain how states aspiring for membership in security organizations must navigate a pattern of political and security hurdles in their quest for membership accession. It then explores Kosovo’s case for NATO membership by examining whether Kosovo has met key political and security benchmarks and devotes significant attention to the settlement dispute with Serbia, the roles played by the U.S. and E.U., and identifies alternative paths for Kosovo’s membership in NATO.

Authors: Ismeti Enes , Toçi Arta 
Published: December 2022

Abstract
The aim of this research is to analyze the political discourse and the language they used in public addresses provided by two former presidents of the United States, specifically, President Barak Obama and President Donald Trump. This research reflects on the material that has been collected for several months which aimed to contribute on the analysis of the corpus, distinctions and similarities, as well as their attitudes towards the public opinion. The objectives of this study are mainly empirical and theoretical. Considering the empirical objectives, this study seeks to explore, identify and categorize the most used words in a political speech according to the categories, form, function and meaning, whereas, the theoretical objectives of this study are to provide a description of the language that is used in major events from well-known politicians when aiming to capture people’s attention. Their rhetorical habits were examined, in every delivery of Mr. Obama’s political speech; his speeches were carefully and well-articulated throughout his 8 year political service in the oval office, portraying him as a kind person. On the other hand, Mr. Trump’s, as a non-politician, more as a businessman, political speeches throughout his campaign and 4 years in the office were very often seen as aggressive, unforeseen, and nonetheless straight to the point.
This study covers the linguistic level analysis as well as semantic and pragmatic levels. Initially, the selected corpora were analyzed using the Ant Conc software regarding frequency of usage and then move into detailed analysis.

Published: December 2022

Introduction. The results of studies devoted to the influence of biological sex on microhemodynamic parameters are ambiguous. Today no studies of sex-specific microhemodynamics evaluated by the new incoherent optical fluctuation flowmetry method (IOFF) have been reported. Objective – to investigate the sex-specific differences of microhemodynamics assessed by the IOFF method in healthy volunteers. Materials and Methods. 27 healthy volunteers (10 men and 17 women) were included in the study. The groups were comparable by sex, age, and main clinical parameters. Perfusion was measured by the IOFF method. Parameters were evaluated while performing an occlusion test on the hand and a local heating test on the dorsum of the foot and the toe. Microcirculation reactivity was calculated as a relative increase of perfusion response to the vasodilation stimulus. Results. Women had significantly lower median baseline perfusion than men on the hand and on the dorsum of the foot (hand: 10 [6; 13] PU vs. 15 [10; 19] PU, p = 0.035; foot: 0.78 [0.68; 0.97] PU vs. 1.13 [0.99; 1.29] PU, p = 0.003). Women were demonstrated to have significantly higher reactivity response to thermal and occlusive stimuli than men (p < 0.05). Thus, at the third minute of heating, women had perfusion increased 5.39 [4.32; 6.64] times and men had 3.47 [3.13; 4.65] times (p = 0.018); after the release of the occlusion women had perfusion increased 1.93 [1.37; 3.02] times and men had 1.14 [1.01; 1.74] times (p = 0.011). Conclusion. Healthy women had been shown to have higher reactivity of microhemodynamics than men. A lower cardiovascular risk women have compared to men could be caused by sex-specific features of endothelium function.

Published: December 2022

Introduction. Cell damage is not the only important mechanism of high-intensity focused ultrasound (HIFU) for cancer therapy; concomitant microcirculation disorders having alterations patterns not studied enough also have high significance. The aim of the study was to analyze perfusion along the tumor perimeter depending on the HIFU exposure. Materials and methods. We used a stand for HIFU therapy (MTL LLC). Mode: 8.2 kW/cm2 intensity at 0.6 mm focal spot at 1.4 MHz, exposure time: 150, 200, 250 and 500 ms. The object of the study is the vascular bed of Pliss lymphosarcoma. Tumor tissue temperature was monitored by a T-8 thermograph (Russia), blood flow was measured by the BLF21 laser Doppler recorder (USA). Results. After HIFU exposure time from 150–250 ms, perfusion was noted to have decreased to 1.06 perfusion units (pf.u) in the central zone (p<0.01) compared to the control, but by the 30 min perfusion has increased to 1.22 pf.un. No signs of perfusion improvement were found in exposure time of 500 ms. In the peripheral zone, against the background of a decrease in blood flow to 3.6 pf. u. (p < 0.05) by 30 min of the experiment, hyperperfusion was restored to 5.86 pf. u. in all exposure time. In the central zone, a sharp decrease in microcirculation was observed, probably caused by damage of blood vessels; in the periphery of the tumor, perfusion changes had a phasic and reversible pattern. Conclusion. An increase of HIFU exposure correlates with an increase of temperature of Pliss lymphosarcoma tissue near the focus of exposure. Specific perfusion changes are recorded in the central and peripheral zones of the tumor when single exposed to HIFU with different time exposure; the severity of changes depends on ultrasound exposure-time and is characterized by a zonal pattern of blood flow distribution due to the formation of zones of irreversible and reversible damage to microcirculation.

Retos de los cuerpos policiales para afrontar los actos criminales durante la protesta social en Chile, Colombia, Ecuador y Perú en tiempos de pandemia
Authors: Vásquez Isaza Juan David 
Published: December 2022

Diversos factores políticos, económicos, sociales y culturales en Sudamérica se han convertido en detonantes fundados y propicios para el uso de la protesta como manifestación de inconformidad comunitaria, pero sus objetivos principales y su sentido como derecho social, ha sido utilizado por algunos actores como instrumento de criminalización y de distorsión de estos medios de expresión públicos, lo que favorece escenarios de desestabilización democrática, afectando la seguridad y la toma de decisiones de las autoridades gubernamentales.
A través de una revisión bibliográfica y la interacción con organismos internacionales de cooperación policial se busca analizar el impacto de la criminalización de la protesta social a nivel regional, mediante la identificación de casos en Chile, Colombia, Ecuador y Perú, resaltando los alcances, los medios utilizados, las características y factores que ponen en riesgo la seguridad regional; por lo tanto, este articulo tiene como orientación las estrategias, que desde la perspectiva académica y de seguridad, deben ser implementadas por los cuerpos de policía, enfatizando en la necesidad de fortalecer la capacidad de cooperación para finalmente definir los retos y desafíos que estas instituciones de seguridad deben adoptar de cara a mitigar el escalonamiento de esta amenaza en Sudamérica.
