Does State Dependence Matter in Relation to Oil Price Shocks on Global Economic Conditions?
Authors: Dufrénot Gilles , Ginn William , Pourroy Marc , Sullivan Adam
Published: April 2024

A common thread in the literature shows that an oil price shock can have a major impact on global economic conditions. We examine the global dimensions of changes to the global oil price and world economic uncertainty using three model types: ordinary least square (OLS); general additive model (GAM); and non-linear vector autoregression (VAR) model with local projections (LP). Our study highlights a positive and statistically significant effect of oil prices on economic uncertainty during non-expansionary periods, yet the impact is negative on economic uncertainty during periods of economic growth. Using a VAR-LP we analyze the global dimensions of a world oil price shock on global economic conditions and investigate whether there is consistency in how an oil price shock influences economic growth, consumer prices and economic uncertainty based on the state of economic conditions. The empirical evidence shows that during an expansionary (a non-expansionary) period, the impact of an oil price shock lowers (elevates) economic uncertainty. The empirical evidence from the three model types taken together indicate a presence of state dependence on the influence of an oil price shock.

Yamashita, Y and Umemura, Y. Effect of high-intensity with short-duration re-warm up on subsequent performance in a cold environment. J Strength Cond Res 38(6): e280–e287, 2024—The aim of this study was to investigate the effect of high-intensity, short-duration re–warm-up (RW) during half time (HT) on subsequent performance in a cold environment. Eleven male subjects (age, 21 ± 2 years; height, 172.4 ± 4.5 cm; body mass, 65.6 ± 7.1 kg; V̇o
2max, 47.5 ± 4.8 ml·kg−1·min−1) performed 2 experimental trials comprising 40 minutes of intermittent cycling exercise, which consisted of 15-second rest, 25-second unloading cycling, 10-second high-intensity cycling, and 70-second moderate-intensity cycling as the first half. In the second half, a cycling intermittent-sprint protocol (CISP) was performed, separated by a 15-minute HT period in cold conditions (5 °C, 50% relative humidity). Two experimental trials were included in a random order: (a) approximately 1 minute of high-intensity, short-duration RW (3 sets of 3-second maximal pedaling [body weight × 0.075 kp]) trial high-intensity intermittent cycling trials (HII); (b) 15 minutes of seated rest trial (CON). Cycling intermittent-sprint protocol consisted of 10 sets of a 2-minute exercise protocol, and each set consisted of 10-second rest, 5-second maximal pedaling (body weight × 0.075 kp), and 105-second active recovery at 50% maximum oxygen uptake (V̇o
2max). Peak power output of 5-second maximal pedaling during CISP was higher in HII trials than in CON trials (HII: 807 ± 81 W, CON: 791 ± 78 W, p < 0.05). There was no significant difference in rectal temperature between trial types (p > 0.05). These results suggest that high-intensity, short-duration RW may be a useful HT strategy for improving subsequent performance in cold environments.

McGrath, R, McGrath, BM, Jurivich, D, Knutson, P, Mastrud, M, Singh, B, and Tomkinson, GR. Collective weakness is associated with time to mortality in Americans. J Strength Cond Res XX(X): 000–000, 2024—Using new weakness cutpoints individually may help estimate time to mortality, but their collective use could improve value. We sought to determine the associations of (a) each absolute and body size normalized cut point and (b) collective weakness on time to mortality in Americans. The analytic sample included 14,178 subjects aged ≥50 years from the 2006–2018 waves of the Health and Retirement Study. Date of death was confirmed from the National Death Index. Handgrip dynamometry measured handgrip strength (HGS). Men were categorized as weak if their HGS was <35.5 kg (absolute), <0.45 kg·kg−1 (body mass normalized), or <1.05 kg·kg−1·m−2 (body mass index [BMI] normalized). Women were classified as weak if their HGS was <20.0 kg, <0.337 kg·kg−1, or <0.79 kg·kg−1·m−2. Collective weakness categorized persons as below 1, 2, or all 3 cutpoints. Cox proportional hazard regression models were used for analyses. Subject values below each absolute and normalized cutpoint for the 3 weakness parameters had a higher hazard ratio for early all-cause mortality: 1.45 (95% confidence interval [CI]: 1.36–1.55) for absolute weakness, 1.39 (CI: 1.30–1.49) for BMI normalized weakness, and 1.33 (CI: 1.24–1.43) for body mass normalized weakness. Those below 1, 2, or all 3 weakness cut points had a 1.37 (CI: 1.26–1.50), 1.47 (CI: 1.35–1.61), and 1.69 (CI: 1.55–1.84) higher hazard for mortality, respectively. Weakness determined by a composite measure of absolute and body size adjusted strength capacity provides robust prediction of time to mortality, thus potentially informing sports medicine and health practitioner discussions about the importance of muscle strength during aging.

Dawson, L, McErlain-Naylor, SA, Devereux, G, and Beato, M. Practitioner usage, applications, and understanding of wearable GPS and accelerometer technology in team sports. J Strength Cond Res XX(X): 000–000, 2024—Monitoring training load is essential for optimizing the performance of athletes, allowing practitioners to assess training programs, monitor athlete progress, and minimize the risk of injury and overtraining. However, there is no universal method for training load monitoring, and the adoption of wearable global positioning system (GPS) and accelerometer technology in team sports has increased the volume of data and, therefore, the number of possible approaches. This survey investigated the usage, applications, and understanding of this technology by team sports practitioners. Seventy-two practitioners involved in team and athlete performance monitoring using GPS and accelerometer technology completed the survey. All respondents reported supporting the use of GPS technology in their sport, with 70.8% feeling that GPS technology is important for success. Results showed that 87.5% of respondents use data from wearable technology to inform training prescription, although only 50% use the data to influence decisions in competition. In addition, results showed that GPS metrics are used more than accelerometer-derived metrics; however, both are used regularly. Discrepancies in accelerometer usage highlighted concerns about practitioners' understanding of accelerometer-derived metrics. This survey gained insight into usage, application, understanding, practitioner needs, and concerns and criticisms surrounding the use of GPS and accelerometer metrics for athlete load monitoring. Such information can be used to improve the implementation of this technology in team sport monitoring and highlight gaps in the literature that will help to design future studies to support practitioner needs.

What if We Seem to Seem and Not Seem? Estimating the Unreasonable Price of Illusionism
Authors: Karak Biplab
Published: April 2024

With its strategic consideration of phenomenal consciousness illusorily seeming to us, illusionism claims to deny phenomenality and thereby obviate the hard problem of consciousness. The problem with illusionism, however, is that, although its thesis appears persuasively simple, it strikes as absurd insofar as the phenomenal illusions themselves also seem as much as phenomenality, keeping no fundamental differences between the two. In short, it reinforces the same phenomenon/issue, i.e., phenomenality, that it claims to deny/avoid. This single absurdity is reflective of its self-refuting nature, and it alone is enough for a rejection of illusionism. However, does illusionism have any reasonable justification to defend itself in the face of the experientially undeniable reality of phenomenal consciousness? This paper attempts to find out if there is any such illusionist justification.
Social Justice in the 21st Century: Is the Welfare State Still a Meaningful Theoretical Construct for Modern Democracy?
Authors: Valantiejus Vaidotas
Published: April 2024

The article examines the ideologem of the decline of the welfare state. The main question is whether the welfare state is still possible in contemporary society. It is argued that the thesis of the impossibility of the welfare state is an ideological statement, and the supposedly objective demise of the welfare state is what M. Foucault called ‘the regime of truth’. The article contrasts the procedural and substantive features of the concept of the welfare state. According to J. Habermas’ theory of legitimation crisis, the welfare state and the social rights it provides are not treated as paternalistic and freedom-restricting measures but rather as the foundation of legitimation.

Tradicionalmente el estudio de los negocios internacionales se ha ocupado de analizar el conjunto de actividades y transacciones internacionales en las que se involucran las empresas. La clasificación como empresas internacionales o empresas multinacionales (EMN) se realiza dependiendo del control y el compromiso ejercido sobre sus operaciones en el exterior. El estudio de la existencia, el desarrollo y los límites de la EMN como fenómeno económico inició a mediados del siglo XX con los aportes de Stephen Hymer, considerado el padre de los negocios internacionales, y de autores como Ronald Coase, Oliver Williamson, Raymon Vernon, Frederick Knickerbocker, Marc Casson, Peter Buckley y John Dunning, entre otros. Este artículo busca hacer un recuento de algunos de los enfoques teóricos del análisis del movimiento internacional de capitales y el surgimiento y evolución de la EMN; para esto, inicialmente se hizo una revisión de los aportes de autores como Rosa Luxemburg, Bertil Ohlin y Ragnar Nurkse, posteriormente se discutió la trascendental contribución de Stephen Hymer, el modelo institucionalista de costos de transacción desarrollado por Ronald Coase y Oliver Williamson, la teoría de la internalización de la EMN de Peter Buckley y Marc Casson, y finalmente el llamado paradigma ecléctico de John Dunning.
Assessment in mutant lines of winter barley using BLUPs
Authors: Dyulgerova B. , Dyulgerov N.
Published: April 2024

Abstract. This study aimed to assess genetic variability for grain yield and yield-related traits of mutant lines of winter barley, employing BLUP methodology. Traits spike length, spikelet number in spike, grain number in spike, grain weight per spike, 1000-grain weight, and grain yield, were evaluated at the Institute of Agriculture - Karnobat, Bulgaria, during 2021/2022 cropping year. The experimental design was a Complete Block Design with four replications, involving 35 genotypes. This included 32 mutant lines, the parent variety Ahil, and two standard varieties, Obzor and Emon. The results showed that mutant lines exhibited superior performance across multiple traits, including grain yield and yield-related traits. The observed high heritability and accuracy of the traits studied suggest a strong possibility for genetic gain through selection. Genetic diversity among the mutant lines, based on BLUP values, revealed substantial genetic differentiation associated with their yield potential. The MGIDI selection strategy was utilized to identify promising mutant lines with high genetic potential. Mutant lines 54/30, 54/49, 54/54, 54/10, and 55/22 were selected based on their predicted genotypic values and favorable characteristics. These lines hold potential for further development as candidate varieties or parents in breeding programs. The use of BLUPs in the selection process proved to be an effective tool for identifying superior mutant lines, further highlighting the usefulness of this approach in barley breeding. The findings of this study also demonstrate the efficacy of sodium azide mutagenesis in generating mutant lines of winter barley with improved yield and yield-related traits.

Published: April 2024

In view of the paradigm shift toward data-driven research in materials science and engineering, handling large amounts of data becomes increasingly important. The application of FAIR (findable, accessible, interoperable, reusable) data principles emphasizes the importance of metadata describing datasets. We propose a novel data processing and machine learning (ML) pipeline to extract metadata from micrograph image files, then combine image data and their metadata for microstructure classification with a deep learning approach compared to a classic ML approach. The ML model attained excellent performances with and without metadata and bears potential for performance improvement of further use cases within the community.

Authors: Byelozyorov Zh. O.
Published: April 2024

The simulation of the operation of devices for determining the coordinates of sound anomalies, which is located on board mobile devices of monitoring systems, is considered. The calculation based on the data of the coordinates of sound anomalies, which were measured in the connected coordinate system of a separate device, coordinates in a single basic system, is substantiated. The model of the error calculation process was built and modeled taking into account the influence of the angular velocity of the carrier device for a separate device. It is proposed based on the results of modeling the hardware and software parts of the device.
This study is devoted to the modeling of devices embedded in mobile monitoring systems designed to detect sound anomalies. These devices play a crucial role in identifying and tracking the coordinates of such anomalies. The research focuses on elucidating the computational methods used to transform the coordinates of sound anomalies, originally measured in a linked coordinate system of individual devices, into coordinates within a single reference system.
An important aspect of this study is the construction of a model to estimate the error accumulation process. This model takes into account the influence of the angular velocity of the carrier on individual components. By simulating various scenarios, the study aims to accurately quantify and understand the sources of errors inherent in the system.
In addition, the study offers recommendations for improving the hardware and software components of the device based on the information obtained during the simulation process. These recommendations include hardware additions and strategic reallocation of software components to mitigate errors and improve the overall efficiency and accuracy of audio anomaly detection systems.

The requirements for the air reconnaissance system using unmanned aircraft systems are being studied. Problematic aspects of the air reconnaissance data processing process are analyzed from the point of view of ensuring the required level of operational efficiency and reliability of intelligence information. The possibility of automating the process of detecting aerial reconnaissance objects on video images is being investigated. A software-hardware module for automated detection and recognition of objects of interest is being developed to increase the level of processing efficiency and reliability of air reconnaissance data. Modern models of detection and recognition of objects of interest based on algorithms of the YOLO platform are studied. The software component of the module is being developed using the YOLOv8 algorithm architecture and a set of data formed in the conditions of air reconnaissance. The analysis of the results of experimental studies shows that: the developed model allows to ensure the required level of operational efficiency of video image processing and the reliability of aerial reconnaissance data; practical implementation of the developed model at ground command and control stations is possible without the use of additional computing equipment. The hardware component of the module is being developed using Raspberry Pi components. The analysis of quantitative evaluations of the efficiency of data processing using the developed software and hardware module on board the UAV of the studied class indicate an increase in time delays compared to the implementation at the command-and-control station, but it allows to ensure the required level of reliability. Further scientific research will be aimed at investigating the peculiarities of the implementation of the conceptual foundations of the developed module for various classes of UAV in order to increase the level of processing efficiency and reliability of aerial reconnaissance data.

Analysis of computer-aided manufacturing systems
Authors: Gusev Sergey S. , Makarov Vadim V.
Published: April 2024

BACKGROUND: Process of design and development of a controlling program starts after the conclusion of the previous stage of the product life cycle and it begins with the work of an engineering center. At this stage, development of new design solutions takes place and technical requirements specification for the developed product is approved with the customer.
AIM: Process of design and development of a controlling program starting after the conclusion of the previous stage of the product life cycle and beginning with the work of an engineering center.
METHODS: Based on that, the drawing of the product including technical requirements is prepared. Then, generally, this drawing is handed over to the department of process engineers-programmers where the design and development of the process control for the product takes place. As a rule of thumb, at this stage, a process engineer seeks advice from a drawing developer to obtain a full information about the product in order to eliminate any mistakes. There are possible cases where at this moment the drawing is given back to the engineering department due to impossibility of product manufacturing caused by lack of manufacturing abilities or poor design solutions making describing of manufacturing technology impossible.
RESULTS: The study result is the fact that the next stage that follows obtaining the technical requirements specification is development of technological process. The technological process should be formulated properly in terms of technology in accordance with internal enterprise standards (each enterprise can have own standards but the formulation structure is unite) and be sufficiently informative for the sake of exclusion of high chances of rejects during manufacturing. As the statistics shows, many enterprises suffer from high reject rate caused by improper behavior of CNC operators because of disappointments to the technological process.
CONCLUSIONS: Based on results of metalworking simulation, the method aimed to optimization of the strategy of machining high-speed metalworking at development of a controlling program has been formulated.
Spontaneous coronary artery dissection in a young woman with signs of connective tissue dysplasia and hereditary thrombophilia: clinical case
Authors: Feoktistova Valeria S. , Boldueva Svetlana A. , Burak Taras Y. , Kretova Veronika E.
Published: April 2024

BACKGROUND: Spontaneous coronary artery dissection (SCAD) is a disease that develops unrelated to intracoronary intervention, atherosclerosis, aortic dissection, or mechanical trauma and causes a false lumen (intramural hematoma) in the wall of the coronary artery (CA) with impaired blood flow in it and myocardial ischemia in the affected region of the CA. SCAD most often develops in young and middle-aged adults (aged ≤50 years); among women, it becomes the culprit in 24%–35% of cases of acute myocardial infarction (MI). SCAD is a risk factor for MI, and incorrect interpretation of the angiographic picture and intravascular imaging methods can lead to incorrect tactics of patient behavior.
CLINICAL CASE DESCRIPTION: This article presents a clinical case of SCAD leading to the development of MI in a young woman with concomitant connective tissue dysplasia and hereditary thrombophilia. The angiographic disease course resembled focal atherosclerosis, and in the course of invasive management, complications had arisen, confirming the probable genesis of coronary artery obstruction.
CONCLUSION: SCAD is a complex disease, with a sudden onset and an ambiguous prognosis. In most cases, SCAD develops in young women in the absence of cardiovascular factors. It is difficult to diagnose because its signs and symptoms are similar to more common diseases, mainly MI. SCAD can masquerade as focal stenosis on an angiogram, mimicking an atherosclerotic plaque. The «gold standard» for diagnosing SCAD is optical coherence tomography (OCT). OCT enables the visualization of the state of all coronary artery walls and elucidates the pathogenetic mechanisms of MI. If performing OCT is impossible after diagnostic coronary angiography in young patients in suspected cases, the likelihood of DST and SCAD risk must be assessed to avoid errors in choosing treatments. The technical accessibility of intracoronary imaging methods reduces the frequency of diagnostic and, consequently, treatment errors.
Solutions of Surface-Wave Dispersion and Attenuation in Stratified Viscoelastic Media Using a Spectral-Element Approach
Authors: Shi Caiwang , Yuan Shichuan , Chen Xiaofei
Published: April 2024

Efficient and accurate calculation for the dispersion and attenuation of the surface waves in viscoelastic media is numerically challenging because the eigen wavenumbers are located in the complex domain. In this study, we propose a semianalytical spectral-element method (SASEM), which can determine the complex eigen wavenumbers by solving linear eigenvalue problems. By simplifying the structure of the eigenvalue problem, we significantly improve the calculation efficiency. The implementation of the frequency-dependent automatic discretization, semi-infinite element, and mode filter guarantees the correctness and accuracy of the modal solutions. Because no root-searching schemes are required, the root-skipping problem is naturally avoided. The numerical tests show that the SASEM can provide sufficiently accurate solutions with much less computation cost than traditional Muller’s method. Meanwhile, SASEM exhibits high flexibility when applied to media the parameters for which vary continuously with depth. To demonstrate the effectiveness of SASEM for complicated dispersion features, the dispersion curves and eigen wavefields of the viscoelastic media with a low-velocity layer are also analyzed. The results of numerical tests indicate the versatility, efficiency, and accuracy of our method. With further study, the proposed SASEM has the potential to become a promising tool for the investigation and retrieval of viscoelastic subsurface structures.

Published: April 2024

Purpureocillium lilacinum, previously known as Paecilomyces lilacinus, is a saprophytic fungus typically found in soil and decaying vegetation. Although it is infrequently pathogenic to humans, recent reports of P. lilacinum infections, primarily affecting the skin and eyes, have shown an increase. This report details a cutaneous infection caused by P. lilacinum in an 89-year-old woman. She presented with a 3-month history of an erythematous patch and nodule on her right forearm. A skin biopsy revealed inflammation, granuloma, and fungal organisms in the dermis. Periodic acid-Schiff (PAS) staining confirmed the presence of fungal elements. The fungal culture of the medium produced colonies with a velvety pink and brown hue. PCR testing on these cultured samples identified P. lilacinum. The patient received a 2-week course of oral itraconazole (200 mg/day), which improved her symptoms. However, ongoing antifungal treatment was necessary. Additionally, due to a recent myocardiac infarction, the patient required a statin. A MIC test was conducted to identify an antifungal drug compatible with statin therapy.

This review addresses the capabilities of stress EchoCG as a simple, non-invasive, non-radiation method for diagnosing occult disorders of coronary blood flow in patients with non-ST-elevation acute coronary syndrome on a low-risk electrocardiogram. The capabilities of the enhanced stress EchoCG protocol are based on supplementing the standard detection of transient disturbances of local contractility, generally associated with coronary artery obstruction, with an assessment of the heart rate reserve, coronary reserve and other parameters. This approach is considered promising for a more complete characterization of heart function during exercise and an accurate prognosis of the clinical case, which allows determining the tactics for patient management not limited to selection for myocardial revascularization.

Authors: Milyukov V. E. , Bryukhanov V. A. , Nguyen C. C.
Published: April 2024

Based on the available modern medical literature, the article summarizes data on the morpho-functional significance of epicardial adipose tissue (EAT) in health and heart failure, analyzes the likelihood and reliability of the formation of the obesity paradox, and also discusses its possible morpho-functional mechanisms. The authors reviewed and analyzed the consequences of the obesity paradox in the aspect of the normal EAT phenotype protectivity. The review proposed ways of further research in this direction aimed at a deep anatomical and physiological analysis and at determining the morpho-functional role of EAT in the adaptive mechanisms of myocardial trophic provision, which may be an important part of the pathogenetic connection between obesity and CHF and, therefore, can improve outcomes in such patients.
“QUEIXADAS” ÀS MILITANTES DE CLUBES DE MÃES: ÀS MULHERES COMO PROTAGONISTAS NOS MOVIMENTOS SOCIAIS DE PERUS
Authors: Pereira Sousa Michele , Martinez Ricoldi Arlene
Published: April 2024

Este trabalho apresenta brevemente a história do distrito de Perus, zona noroeste da cidade de São Paulo, para demonstrar que, desde o surgimento dos movimentos sociais do território, as mulheres sempre estiveram presentes. Sua articulação teve início junto à luta dos trabalhadores da Companhia Brasileira de Cimento Portland Perus. Mesmo não tendo mulheres no quadro de funcionários da indústria, elas se fizeram presentes nas duas greves organizadas pelos trabalhadores, a de 1958 e a de 1962. Os grevistas e suas famílias receberam o apelido de “queixadas”, o qual adotaram como símbolo da não-violência ativa ou firmeza permanente. As mulheres foram protagonistas na greve de 1962, pois enquanto os familiares homens estavam em greve, elas sustentaram seus lares. A exemplo da luta das “queixadas” em 1970 eclode o número de clubes de mães em Perus, enquanto movimento social de base elas lutam por seus direitos.

SEDUÇÃO, MATERNIDADE E CASAMENTO: O CASO DA JOVEM ANNA MARIA DE SOUZA (MARIANA, 1750)
Authors: Sales Dias Beatriz
Published: April 2024

O objetivo deste trabalho é entender, através de um processo-crime de defloramento, de 1750, na cidade de Mariana, Minas Gerais, alguns aspectos da situação da mulher seduzida e engravidada no período colonial. Acreditamos ser fundamental para o entendimento da maternidade nesse período, perceber a realidade de mulheres que se tornaram mães solteiras após promessas de casamento, tendo em vista que este era, justamente, um recurso da Igreja Católica para adestrar a população feminina. Ao trabalhar com uma fonte jurídica, procuramos observar como essa personagem feminina se apresentava e como foi julgada pelo aparato judicial. Procuramos estabelecer uma comparação entre os argumentos que ela evocava a seu favor e os levantados pelo seu adversário — no caso, o pai de seu filho — perante a justiça. Analisando detidamente o processo, buscamos compreender melhor quais eram os objetivos dessa mulher ao entrar na justiça e como se beneficiou com a resolução dessa contenda.
The Motif of Violin in Testimonies and Representations of the Holocaust
Authors: LEOCIAK JACEK
Published: April 2024

Autor sięga do różnego typu źródeł: dzienników, zapisków, relacji, dokumentów i innych świadectw
z czasów Zagłady, pochodzących zarówno od ofiar, jak i sprawców, oraz do powieści o Zagładzie
i muzyki związanej z tym doświadczeniem, by śledzić motyw skrzypiec w różnorodnych reprezentacjach
Holokaustu. Artykuł ma charakter rekonesansu, skupia się na wybranych źródłach
i podejmuje niektóre tylko wątki. Zasadnicze jest pytanie o funkcję kulturowych symboli w formułowaniu
i przekazie tak fundamentalnego doświadczenia, jakim była Zagłada. Okazuje się, że
skrzypce – nieodłączny atrybut żydowskiej kultury muzycznej w jej najbardziej stereotypowej formule,
w ujęciu pospolitym i najszerzej spopularyzowanym – są silnie obecne w tych przekazach,
i to zarówno jako realny przedmiot – instrument muzyczny – jak i (a może przede wszystkim)
jako topos, metafora, symbol. Motyw funkcjonuje w rejestrze wysokim, ale coraz częściej da się
go znaleźć w powstających współcześnie przekazach należących do rejestru niskiego literatury,
osuwającego się w rejony kiczu. Strumień opowieści o skrzypcach i skrzypkach w czasie Zagłady
nie wysycha, przeciwnie – fala zdaje się wzbierać.
Sharpening the Portrait (Michał Głowiński)
Authors: KISIEL MARIAN
Published: April 2024

W szkicu podjęto refleksję nad portretem jako gatunkiem literackim, funeralnym i biograficznym.
Skupiając się na Tęgich głowach Michała Głowińskiego, autor pokazuje chwyty stosowane przez
eseistę po to, by ukazać osobę portretowaną jako postać wielowymiarową. Korzystając z anegdoty,
plotki czy własnych wspomnień, Głowiński częstokroć tworzy portrety intelektualne kilku
pokoleń polskiej inteligencji. Autor szkicu twierdzi, że Tęgie głowy to kolekcja esejów, w których
rzeczywistość, jaka naprawdę istniała, dla czytelnika, który jej nie przeżył, więc nie jej zna, albo
zna z niespójnych przekazów, jest w jakimś sensie fikcjonalna i fantastyczna.

Exploring the potential of internal communication and employee relations for effective staff performance in Nigeria customs service
Authors: Maiwada Abdullahi Aliyu , Oshionebo Barth
Published: April 2024

Organizations in the modern, global environment have moved away from traditional methods of communication and toward creating all-encompassing plans that revolve around the engagement and motivation of their workforce. This change highlights the critical function of strategic internal communication, a still-emerging but increasingly important field of study and practice in the business sector. The modern workplace sees a change in the roles that employees play, with workers taking on more and more duties that were previously related to public relations. Understanding this shift in PR practice requires an understanding of role expectations, as norms and expectations have a significant impact on communication behavior and, in turn, organizational performance. To interpret the data in this context, a content analysis of secondary data was conducted. This made it possible to assess the body of knowledge in order to determine its applicability, consistency, replication, and rebuttal. The study makes the case that paramilitary organizations, like the Nigeria Customs Service, have internal communication procedures that are different from those of traditional corporate organizational structures. Given the agency’s diverse responsibilities in income generation, trade facilitation, and the abolition of smuggling, this discrepancy is especially noticeable. The study shows that the relationship between internal communication and employees’ job performance was mediated by employee participation and job satisfaction.

Published: April 2024

There is a need for novel alternatives to the medical use of allopurinol. In this sense, the present study obtained a leaf extract of L. leucocephala, and its chemical composition, inhibitory action against xanthine oxidase (XO) in vitro, inhibitory interaction between the extract and allopurinol, and the inhibitory action on XO in vivo using mice treated with potassium oxonate and hypoxanthine were determined. Polyphenol and flavonoid compounds were found in the leaf extract. For the leaf extract, the IC50 and maximal values were 334.60 µg/mL and 46.4 % for the inhibition of XO. The 3:1 ratio combination of allopurinol and extract showed IC50 and waDRI values of 1.35 µg/mL, 1.13 (allopurinol) and 1015.72 (extract) to inhibit XO, resulting in a synergistic interaction against XO in vitro. This combination also enhanced the therapeutic success in the mouse model compared with allopurinol administered alone. The present study presents the first evidence for the use of an allopurinol and L. leucocephala extract combination at a 3:1 ratio as a substitute for the administration of allopurinol alone.
