Authors: Achour Bouchra , Ziadi Abdelkader , Belarbi Lahcen , Mokaddem Allel , Lousdad Abdelkader
Published: November 2022

In this research work, waste plastic bottle caps made of high-density polyethylene (HD-PE) were reincorporated as a matrix and reinforced by alfa short fibers and natural pozzolan particles. Using different weight percentages of both fillers of 5 wt% up to 30 wt%, three types of bio-composite materials have been produced; alfa short fibers/HDPE, pozzolan particles/HDPE, and alfa fibers pozzolan/HDPE. Specimens for each type of the biocomposites were prepared through the compression molding method. The objective of this study is to investigate the effect of different content of alfa short fibers and pozzolan particles on the mechanical and morphological properties of the recycled HDPE matrix. Tensile test results revealed an enhancement in the mechanical properties for the three types of the biocomposites, an increase in tensile strength reached the maximum of 3573 MPa plus an interesting improvement in Young’s modulus with a maximum value of 3696 MPa. The toughness of the neat recycled HD-PE decreased by 212% by adding the natural filler whereas the modulus of resilience exhibited an increase of 138% compared to the neat recycled HD-PE. Therefore, the good rheological behavior of these bio-composites makes it possible to produce competitive materials and allows the reduction of plastic waste in the environment.
Characterizing CaCO3 particle dispersion in blown film

Published: November 2022

A novel method for the visualization and quantification of the state of dispersion of calcium carbonate particles in thin blown polymer films is described. Particle imaging was achieved by elemental mapping using energy dispersive spectroscopy. This generated outlines of particles and agglomerates located close to the film surface. ImageJ software facilitated the extraction of the corresponding Feret diameters. Finally, the Bootstrap technique was used to estimate confidence intervals for the kurtosis of the Feret particle size distribution. Kurtosis is a statistic that describes the shape of a distribution’s tails in relation to its overall shape. It therefore provides a measure that characterizes the degree of particle agglomeration. The proposed procedure was applied to analyze high-density polyethylene films prepared using different calcium carbonate masterbatches in which formulation parameters were varied.
Road Use Contributions to Energy Consumption and Greenhouse Gas Emissions for Two Flexible Pavement Maintenance Strategies
Authors: Poor Noreen , Braham Andrew
Published: November 2022

Energy consumption and greenhouse gas (GHG) emissions based on a 10-km 4-lane flexible pavement road were calculated for two maintenance strategies: conventional mill and fill treatments for strategy I and preventative treatments and a cold in-place recycling treatment for strategy II. Comparative calculations featured the road maintenance and use stages of a simplified life cycle assessment. The maintenance stage included the material production, mix manufacturing, and material transport that support road maintenance activities. Energy consumption and GHG emissions for maintenance activities were ∼33 GJ/lane/km/yr and ∼1.6 tonnes/lane/km/yr for strategy I, respectively, and ∼22 GJ/lane/km/yr and ∼1.4 tonnes/lane/km/yr for strategy II. Also calculated were the excess energy consumption and excess GHG emissions by vehicles because of road roughness, characterized by the international roughness index. These results were ∼710 GJ/lane/km/yr and 50 tonnes/lane/km/yr for strategy I, respectively, and ∼300 GJ/lane/km/yr and ∼21 tonnes/lane/km/yr for strategy II. Preventative road maintenance and in-place pavement recycling have the potential for environmental and economic benefits to both road builders and road users.
Monitoring and Simulating the Responses of Four Flexible Pavement Test Sections under Heavy Vehicle Loading
Authors: Rahman Shafiqur , Erlingsson Sigurdur
Published: November 2022

For mechanistic-empirical design of pavements, it is essential to accurately predict the responses of the structure that are caused by the design traffic loading. The aim of this study was to compare the simulated responses of pavements with real measurements under heavy vehicle loading. With this objective, four instrumented test sections were built in northern Sweden—about 100 km north of the Arctic Circle. These test sections differed in material quality of the various layers. Each test section was instrumented with pressure cells and strain sensors that measured the pavement response to external loading. Climatic variables were monitored through a weather station as well as temperature and moisture sensors installed in the road structures. Response measurements were carried out using 25-m-long 10-axle vehicles with gross weight of 90 tons. For the simulations of the responses of these test structures under the same vehicular loading, a multilayer elastic theory–based program called ERAPave was used. The required material properties for the simulations were based on laboratory testing of core-drilled samples from the sites. For the simulations, three combinations of material characterizations were considered: (a) linear elastic (LE) all layers, (b) nonlinear (NL) unbound layers, and (c) viscoelastic (VE) asphalt layers. Acceptable agreement between the simulations and measured responses were observed. Generally, the responses calculated based on LE and NL analyses were indistinguishable, whereas the VE analyses showed somewhat lower amplitude peaks.
External and global, or internal and local? Which main factors shape the organisational culture of shared service centres of transnational corporations in Poland?
Authors:   SGH Warsaw School of Economics, Poland, Niewierko Maria
Published: November 2022

Organisational culture has been the topic of research and in-depth analysis for around fifty years, emphasising the multifaceted nature and operationalisation challenges of organisational culture. Studies on its manifestations (i.e. values, behaviours, symbols) and functions have been conducted in relation to corporations, perceived as one entity rather than its subsidiaries. The aim of this article is to investigate the factors shaping the organisational culture of the growing number of shared service centres (SSC) of transnational corporations in Poland, an area that has not yet been thoroughly explored. The article is both theoretical and empirical, with the theoretical part devoted to the characteristics of the growing numbers of SSCs in Poland and a comprehensive classification of environmental factors in which SSCs function, while in the empirical part the author conducted statistical tests regarding the choice of dominant factors shaping SSC culture. A practical dimension of the study is the ranking list of factors shaping the SSC organisational culture: at the top of the rank are the factors related to the activity profile (both for the SSC and parent company) and human capital factors (age, competences, qualifications, employee gender both for the SSC and the parent company). The reverse approach to culture, concentrating more on the process of shaping it rather than an analysis of the actual state and the specificity of the culture, brings added value to the study.
Corporate social responsibility and project management: towards a better understanding of their relationship

Published: November 2022

The main purpose of this article is to identify the fields of convergence, if any, between two management concepts and business practices, namely Corporate Social Responsibility (CSR) and Project Management (PM). To achieve the formulated goal, systematic literature review (SLR), including bibliometric analysis, LOESS regression analysis, and text mining, was performed. This analysis allowed us to distinguish five categories corresponding to the distinctive, related research areas combining CSR and PM constructs. Within these categories we were able to identify the most important characteristics of the linkages between both concepts.
Neural Correlates of Sensory Eye Dominance in Human Visual White Matter Tracts
Authors: Chan Ailene Y. C. , Chang Dorita H. F.
Published: November 2022

A significant proportion of the human neurotypical population exhibits some degree of sensory eye dominance (SED), referring to the brain’s preferential processing of one eye’s input versus another. The neural substrates underlying this functional imbalance are not well known. Here, we investigated the relationship between visual white matter tract properties and SED in the human neurotypical population. Observers’ performance on two commonly used dichoptic tasks were used to index SED, along with performance on a third task to address a functional implication of binocular imbalance: stereovision. We show that diffusivity metrics of the optic radiations (ORs) well predict behavioral SED metrics. We found no relationship between SED and stereosensitivity. Our data suggest that SED is not simply reflected by gray matter structural and functional alterations, as often suggested, but relates, at least in part to the microstructural properties of thalamocortical white matter.

Published: November 2022

The human action observation network (AON) encompasses brain areas consistently engaged when we observe other's actions. Although the core nodes of the AON are present from childhood, it is not known to what extent they are sensitive to different action features during development. Because social cognitive abilities continue to mature during adolescence, the AON response to socially-oriented actions, but not to object-related actions, may differ in adolescents and adults. To test this hypothesis, we scanned with functional magnetic resonance imaging (fMRI) male and female typically-developing teenagers (n= 28; 13 females) and adults (n= 25; 14 females) while they passively watched videos of manual actions varying along two dimensions: sociality (i.e., directed toward another person or not) and transitivity (i.e., involving an object or not). We found that action observation recruited the same fronto-parietal and occipito-temporal regions in adults and adolescents. The modulation of voxel-wise activity according to the social or transitive nature of the action was similar in both groups of participants. Multivariate pattern analysis, however, revealed that decoding accuracies in intraparietal sulcus (IPS)/superior parietal lobe (SPL) for both sociality and transitivity were lower for adolescents compared with adults. In addition, in the lateral occipital temporal cortex (LOTC), generalization of decoding across the orthogonal dimension was lower for sociality only in adolescents. These findings indicate that the representation of the content of others' actions, and in particular their social dimension, in the adolescent AON is still not as robust as in adults.

SIGNIFICANCE STATEMENTThe activity of the action observation network (AON) in the human brain is modulated according to the purpose of the observed action, in particular the extent to which it involves interaction with an object or with another person. How this conceptual representation of actions is implemented during development is largely unknown. Here, using multivoxel pattern analysis (MVPA) of functional magnetic resonance imaging (fMRI) data, we discovered that, while the action observation network is in place in adolescence, the fine-grain organization of its posterior regions is less robust than in adults to decode the abstract social dimensions of an action. This finding highlights the late maturation of social processing in the human brain.

Spontaneous bleeds are a leading cause of death in the pediatric JAG1‐related liver disease Alagille syndrome (ALGS). We asked whether there are sex differences in bleeding events in patients, whether Jag1Ndr/Ndr mice display bleeds or vascular defects, and whether discovered vascular pathology can be confirmed in patients non‐invasively. We performed a systematic review of patients with ALGS and vascular events following PRISMA guidelines, in the context of patient sex, and found significantly more girls than boys reported with spontaneous intracranial hemorrhage. We investigated vascular development, homeostasis, and bleeding in Jag1Ndr/Ndr mice, using retina as a model. Jag1Ndr/Ndr mice displayed sporadic brain bleeds, a thin skull, tortuous blood vessels, sparse arterial smooth muscle cell coverage in multiple organs, which could be aggravated by hypertension, and sex‐specific venous defects. Importantly, we demonstrated that retinographs from patients display similar characteristics with significantly increased vascular tortuosity. In conclusion, there are clinically important sex differences in vascular disease in ALGS, and retinography allows non‐invasive vascular analysis in patients. Finally, Jag1Ndr/Ndr mice represent a new model for vascular compromise in ALGS.

Investigating the Effects of Venlafaxine on Oxidative Stress and Exploring its Relationship to Neurodegenerative Disease
Authors: Alhafi Ladees , Gauvreau Nicole L. , Craig Paul M.
Published: November 2022

The rise in presence of pharmaceuticals in wastewater effluent has had behavioural effects on fish, which this study aimed to investigate.⁴ The pharmaceutical studied was venlafaxine (VEN), a commonly prescribed antidepressant.⁴ Previous studies have shown that venlafaxine contributes to oxidative stress.³ Notably, oxidative stress has been linked to neurodegeneration and plays a role in the pathogenesis of neurodegenerative diseases, such as Alzheimer’s, and Parkinson’s in humans.¹

This study applied a novel approach through in vitro methods to directly expose zebrafish brains to varying VEN concentrations (0.01, 0.1, and 1 μg/L) and quantify oxidative stress. Zebrafish brains were used due to their neuroanatomical similarity to humans.¹⁴ Results demonstrated decreases in cell viability, and increases in antioxidant enzyme activity (catalase and superoxide dismutase) with rising concentrations of VEN.

These findings demonstrate increases in oxidative stress, which was indirectly measured by antioxidant enzyme activity, as well as the effects of VEN on cell viability and protein amounts in the brain cells. These results indicate a possible link between venlafaxine exposure and increased risk of neurodegeneration in humans. Further investigation should be done to examine the association between venlafaxine concentrations in water and increased incidence of neurodegenerative disease in mammalian brains.
Food Insecurity and Finding a Way Forward: The Right to Food
Authors: Abbas Fatima
Published: November 2022

The right to food protects the right of all human beings to live free from hunger and food insecurity, with dignity. Despite Canada’s developed image on the world stage, there are Canadians that still lack the ability to consume adequate quantities and qualities of food. The causal link between food insecurity and poverty has been wellestablished, but much focus still lies on downstream approaches aimed at addressing the hunger instead of the root problem. This entry provides a historical background for the current state of food security in Canada, highlights the steps currently being taken to control the issue, and presents issues of equity to showcase the disproportionate impact of food insecurity in this country. The right to food as a framework to improving both availability of and access to food is proposed as a guiding principle to tackling food insecurity in Canada, in addition to suggestions that allow accountability and equitable and just systems to flourish.
RECEPTION OF ANCIENT AESTHETIC CATEGORIES IN PYOTR CHAADAYEV’S FIRST “PHILOSOPHICAL LETTER”
Authors: Suvorova Irina
Published: November 2022

The relevance of the study is due to the need for an aesthetic analysis of a famous journalistic work of Pyotr Chaadayev, which in the history of philosophy has been studied in detail from the ethical, epistemological, ontological, and theological perspectives, but the aesthetic aspect has been overlooked. The problem of identifying the reception of ancient aesthetic categories in the most famous Russian philosophical letter of the first half of the 19th century is associated with a change of cultural eras and is of interest in terms of preserving the content of the categories of aesthetics that was laid down by Plato and Aristotle. The research methodology includes the text analysis method and the comparison of the content of aesthetic categories of ancient philosophers and Chaadayev. The study revealed that Chaadaev in his letter uses the reception of the Socratic dialogue, adapted for his time, which suggests the author’s commitment to ancient traditions. Chaadaev’s most popular aesthetic categories are the sublime and the base, as well as mimesis (he uses the word “imitation” in his letter). As a result, it turns out that while characterizing Western European culture the philosophical letter’s author correlates it with the category of the sublime, which is close in content to the sublime of the Platonists and Pseudo-Longinus. The opposite category of the base in the Aristotelian interpretation, from Chaadaev’s point of view, best describes Russian history and culture. According to the results of the comparison, the reason for such a bitter picture of domestic existence found by the author seems logical – it lies in the mimesis or imitation, which in Chaadaev’s definition clearly manifests the traces of both Platonic and Aristotelian meanings. As a result, the letter obviously demonstrates the reception of ancient aesthetic categories. However, it can be noted that the entire composition of the work is built on the contrast between the sublime and the base. It was this contrast that created the plot conflict of the letter, which caused a stir among the nineteenth-century readers and leaves no one indifferent to this day.
On virtue epistemology in anglophone philosophy
Authors: Sidorova Stefaniia
Published: November 2022

Virtue epistemology is one of the most popular approaches to epistemological research in Anglophone philosophy. However, it is little known in Ukraine. The article aims to familiarize its readers with the making of virtue epistemology, presenting parallels with virtue ethics. The au- thor makes an attempt to determine the place that virtue epistemology holds in modern philo- sophical discourse. The article provides a brief overview of the main research topics, the biggest controversies within the field, and the systematisation of classification types within the field. The author considers responsibilist and reliabilist approaches to the definition of intellectual virtue. Furthermore, she demonstrates the importance of the Gettier problem for the formation and development of virtue epistemology theories. The article serves as a preliminary sketch of the current state of the Anglophone epistemo- logical discussion presenting research in the field of virtue epistemology from its appearance to the present day. The overview nature of the article is used to test proposed translations of modern epistemological terminology in Ukrainian. The primary goal of the article is to introduce virtue epistemology to the Ukrainian philosophical discourse.

OBJECTIVE

The pediatric sepsis literature lacks studies examining the inpatient setting, yet sepsis remains a leading cause of death in children’s hospitals. More information is needed about sepsis arising in patients already hospitalized to improve morbidity and mortality outcomes. This study describes the clinical characteristics, process measures, and outcomes of inpatient sepsis cases compared with emergency department (ED) sepsis cases within the Improving Pediatric Sepsis Outcomes data registry from 46 hospitals that care for children.

METHODS

This retrospective cohort study included Improving Pediatric Sepsis Outcomes sepsis cases from January 2017 to December 2019 with onset in inpatient or ED. We used descriptive statistics to compare inpatient and ED sepsis metrics and describe inpatient sepsis outcomes.

RESULTS

The cohort included 26 855 cases; 8.4% were inpatient and 91.6% were ED. Inpatient cases had higher sepsis-attributable mortality (2.0% vs 1.4%, P = .025), longer length of stay after sepsis recognition (9 vs 5 days, P <.001), more intensive care admissions (57.6% vs 54.1%, P = .002), and greater average vasopressor use (18.0% vs 13.6%, P <.001) compared with ED. In the inpatient cohort, >40% of cases had a time from arrival to recognition within 12 hours. In 21% of cases, this time was >96 hours. Improved adherence to sepsis treatment bundles over time was associated with improved 30-day sepsis-attributable mortality for inpatients with sepsis.

CONCLUSIONS

Inpatient sepsis cases had longer lengths of stay, more need for intensive care, and higher vasopressor use. Sepsis-attributable mortality was significantly higher in inpatient cases compared with ED cases and improved with improved sepsis bundle adherence.
Бінарність політичної ідентичності: теоретико-методологічний аналіз
Authors: Ісаєва Наталя
Published: November 2022

В статті розкривається бінарний характер концепту «політична ідентичність» у топології сучасного політико-філософського дискурсу, а саме: «індивідуальне / колективне», «національне / наднаціональне», «ми / вони», «минуле / теперішнє». Виявлено, що бінарна опозиція «індивідуальне / колективне» відноситься до сфери сущого або онтологічного рівня політичної ідентичності і розкриває її в межах індивідуального носія, і тут задіяні психологічний напрямок, символічний інтеракціонізм, драматургічна концепція, й у межах колективного носія, і тут залучені концепція зіткнення цивілізацій С. Хантінгтона, конструктивізм А. Вендта, теорія уявного співтовариства Б. Андерсона, по-третє, у комплементарності та колективності.

Встановлено, що бінарна опозиція «норма / цінність» відноситься не до сфери сущого, а до сфери належної або дії, тобто розкриває практичну спрямованість політичної ідентичності. З’ясовано, що бінарна опозиція «національне / наднаціональне» відноситься до культурно-онтологічного рівня політичної ідентичності, й розкриває її як феномен епохи Модерну з його раціональністю, тотальністю секуляризації, атомізацією та омосадуванням суспільства, виникненням націй-держав.

Визначено, що бінарна опозиція «ми / вони» відноситься до маргінального або прикордонного рівня політичної ідентичності та характеризує сукупність та взаємозв'язок соціально-політичних, національних, релігійних процесів ототожнення та відмінності, а також символічних, екзистенційних, соціально-політичних проблем «іншого» та відчуження. Встановлено, що бінарна опозиція «минуле / теперішнє» відноситься до культурно-історичного рівня політичної ідентичності і містить у собі апологію історичного підходу, згідно з яким минуле, завдяки феномену культурної пам'яті, укоріненому в міфах, обрядах, традиціях, впливає на сьогодення та майбутнє, а також апологію антиісторичного підходу з його критикою історицизму та відстоюванням політичних (демократія), економічних (вільний ринок), інтелектуальних (влада розуму та критицизм) ідеалів «відкритого суспільства» на противагу традиціоналістському або закритому.
Український науковий центр у Празі під час радянської окупації навесні 1945 року
Authors: Кокош Артем
Published: November 2022

Український науковий центр у Празі був основним представником української науки і освіти в Європі з 1921 по 1945. У час радянської окупації України Прага стала єдиним можливим містом для вільних досліджень історії, етнології, української мови, права, економіки, політики та інших наук. Освітні і наукові студії зазначених наук були пов’язані з Українським вільним університетом. Багато українських науковців, які працювали в цих галузях, приїхали до університету з СРСР і з європейських країн. На відміну від інших українських культурних і наукових центрів університет був одним з небагатьох, які здійснювали освітню діяльність.

Відтак, мета дослідження полягає у тому, щоб прослідкувати зміни наукового життя університету після радянської окупації Праги, акцентуючи на проблемі переміщення вищої школи до іншої країни. Така проблема випливала з потреби збереження наукового центру, що діяв у Чехословаччині. Варто згадати, що отримавши підтримку президента Томаша Масарика, університет переїхав до Праги з Відня. Протягом майже двадцяти п’яти років університет був основним науковим і освітнім центром українців у Європі і пройшов різні періоди історії. Разом з Музеєм національно-визвольної боротьби, Українським технічно-господарським інститутом та іншими науковими організаціями, університет міг представляти українську культуру і науку закордоном.

Новизна дослідження випливає зі спроби виокремити основні пропозиції щодо діяльності університету навесні 1945 року – залишитися чи покинути чеську столицю з аналізом подальшої долі українського наукового центру. Результати дослідження доводять, що університет не було перенесено до Баварії, а чеську столицю залишала частина науковців. За рішенням сенату університет продовжив працювати у Празі. Усе майно університету після окупації, більшість матеріалів архіву і бібліотеки були вивезені до СРСР. Професори, які залишилися у місті були заарештовані і ув’язнені в радянських тюрмах. До Баварії могли дістатися кілька професорів, що почали відновлювати університет без зв’язку до Праги.

The effects of clinoptilolite on milk copper (Cu), lead (Pb), zinc (Zn), cadmium (Cd) and iron (Fe) concentrations, proinflammatory cytokine responses, oxidative stress status, whole blood cell counts and liver and kidney functions were investigated in dairy cows exhibiting no signs of any kind of toxicity. Clinoptilolite was added to the feed at a dose of 200 mg kg−1 body weight in the clinoptilolite-treated group (n = 14), but was not added to the feed in the control group (n = 7). In the milk samples (n = 21) collected before the experiment, the Cu, Pb, Zn, Cd and Fe values were 0.021 ± 0.020, 0.104 ± 0.01, 3.42 ± 0.32, <0.000, 0.56 ± 0.34 ppm, respectively. At the end of the experiment (30th day), among the elements measured in milk samples collected from the clinoptilolite-treated group, only the Pb value (0.076 ± 0.01) was lower than the 0-day value of the clinoptilolite-treated group (0.104 ± 0.01) and the 30th-day value of the control group (0.105 ± 0.01) was found to be statistically lower. Changes determined at the end of clinoptilolite application in serum superoxide dismutase (SOD), malondialdehyde (MDA), albumin, glucose, urea and urine creatinine/urine total protein (uCr/uTP) values, which were interpreted as the effect of lead exposure before the trial, were evaluated as the positive effect of clinoptilolite. It was concluded that the addition of clinoptilolite to the feed in dairy cows caused a significant decrease in the amount of Pb in milk, and positive changes in the parameters related to oxidative stress in serum and in parameters related to renal function.
