Psychometric evaluation of a momentary assessment of perceived social support
Authors: Woods William C. , Wright Aidan G.C.
Published: July 2024

Perceived social support is an important construct because of its main effects on good mental and physical health. Although historically viewed as a trait-like construct, there is growing interest in perceived social support as a dynamic construct that ebbs and flows over time and across situations. Consequently, there is a need for an instrument that is psychometrically validated for use in ecological momentary and ambulatory assessment protocols. The current study evaluated the psychometric performance of a momentary assessment of perceived social support (MAPSS) using five archival datasets. Validity of the MAPSS was assessed by comparing its multilevel associations with a number of momentary, daily diary, and cross-sectional measures with pre-registered hypotheses derived from the existing literature. Results were generally in line with hypotheses. In addition, results supported the strong multilevel, interitem reliability of the MAPSS. Across the five samples, the MAPSS generally met expectations as a reliable and valid measure of momentary perceived social support.
Frequency and distribution of protest stickers: An ethnographic study at a university city in the south-west of England
Authors: Hill Steve
Published: July 2024

Protest stickers, as a form of street art, can be located in city areas of high footfall. Individualised interpretation of protest stickers relies on the conflation of semiotics and active subjectivity. This paper outlines the results of an ethnographic study detailing the frequency and distribution of stickers around a university campus. The paper draws on cultural criminology’s verstehen to subjectively explore four stickers from differing political domains describing how their presence is interwoven with the societal and geographical landscape of the site of study. The limitations of the work are discussed and possibilities for future studies to address these are provided.

Authors: Aryal Narayan Prasad , Shah Sarita Kumari , Dhakal Anisha
Published: July 2024

Despite the fact that many women hold leadership positions, there has been limited research on the factors influencing leadership positions among female entrepreneurs. Thus, the purpose of this study is to delve into the numerous factors, namely, gender stereotypes, career growth, and economic constraints that affect leadership positions across family support, among women entrepreneurs residing in Ward 4 of Kathmandu Metropolitan City. The study is guided by a quantitative research approach that involves descriptive, causal, and relational design. The described data were gathered from 102 respondents using a structured questionnaire. The data were analysed using IBM SPSS version 20 with various tools, such as the mean, median, standard deviation, variance, independent sample t-test, correlation, and regression. According to the study, there is a positive relationship between gender stereotypes, career growth, economic constraints, and leadership positions among women entrepreneurs, implying that women who are treated equally by society, who are self determined, and who are focused on achieving higher goals are more likely to achieve a leadership position. Similarly, family support made a significant difference for women who aspire to be leaders. The study revealed that gender stereotypes, career growth, and economic constraints all had a significant and positive impact on women entrepreneurs' leadership positions.

Oil Economy and Society of Nigeria’s Niger Delta Region, 1956-2019
Authors: Onor Kester , Ityonzughul Thaddeus T.
Published: July 2024

This paper studies the oil economy with a particular focus on the Nigeria’s Niger Delta Region. It argues that since the discovery and exploration of oil in commercial quantities in the Region, it has become both a blessing and a curse. It is a blessing because it has provided wealth to the people and government of the region. Some indigenes of the Nigeria Delta are owners of the oil wells others are employed to work with the oil multi-national companies like Chevron, Texaco, Shell Petroleum Development Company, Agip Oil Company, et cetera.  The exploration of oil in the area under review is also a curse because it has negatively affected plants and animals (that is the destruction of flora and fauna); it has destroyed the ecosystem of the area.  Using survey and documentary methods of data collection; the paper reveals that despite the discovery and exploration of oil in the said region, Nigeria’s Delta Region has remained one of the underdeveloped regions of the country. This is to say that the impact of the oil industry on the economy and society of the people is marginally felt. Based on the foregoing, these policy options are made. The government should give immediate attention to the indigenes of the region where crude oil is being extracted from. This will reduce the unrest in that region. The government should establish an institution that will ensure that the multinational oil companies are socially responsible to their host communities. Environmental pollution and the adverse effects on the host communities of oil exploration sites in the Niger Delta is an important issue that requires urgent and prompt attention because petroleum production forms the major natural-based resources on which the country depends. Therefore, Policymakers of the various oil exploration companies should realize that there is a need to protect the health, safety, and welfare of these communities. The communities and the inhabitants have to be well protected and some of the health and safety measures, which members of the company staff benefit, should be extended to members of the host communities to improve their standard of living.

Published: July 2024

Traffic violations are no longer commonplace among society. This often happens in the community, sometimes even causing economic and physical losses due to traffic accidents. Positive law in Indonesia has explicitly regulated traffic safety rules which are regulated in Law Number 22 of 2009 concerning Road Traffic and Transportation. To study this, researchers took the research location Numbing Island, which is one of the islands in the Riau Islands Province. And from a criminological perspective, researchers want to examine in more depth what is the basis for the perpetrator to commit this offense. The research method used is empirical juridical research. As support in building the arguments for this research, researchers used primary and secondary reference materials. Data collection techniques used by researchers include observation methods, interviews and literature review. The research data analysis technique was carried out using a qualitative method, then in developing a line of thinking, the researcher used a deductive method. The results of this research show that the level of traffic violations on Numbing Island is sociologically caused by a lack of public awareness on the grounds that the application of traffic laws in the island area is not necessary, in terms of law enforcement factors, supervision by Bhabinkamtibmas is still not strictly implemented so that there is a form of negligence on the part of the authorities. law enforcers to enforce traffic regulations.
IMPACTS OF CONTAINMENT AND ELEVATION ON CREATED MARSH PLANT COMMUNITY AND ECOSYSTEM DYNAMICS
Authors:   , Stoner Kevin
Published: July 2024

Coastal marsh restoration is increasing globally, as marshes are impacted by anthropogenic impacts. Billions of dollars are allocated to marsh restoration in the Mississippi River delta where wetland loss rates are extremely high. The recovery of structural and functional attributes of created marshes varies by attribute measured and project. Here, two marshes created in 2018 and one natural marsh were used to examine how variations in hydrologic connectivity and marsh elevation influence subsurface hydrology and salinity, vegetation community structure, soil properties, accretion, and denitrification. I established a comparative field study in a created marsh contained within a higher elevation containment dyke (Confined), an unconfined created marsh where the dredge sediment was allowed to settle naturally (Unconfined), and a nearby natural marsh on the northeast shore of Lake Pontchartrain in Big Branch National Wildlife Refuge, Louisiana. Most marsh creation projects in Louisiana have a surrounding higher-elevation containment dyke to limit the loss of dredge sediment. The long-term effects of containment dykes on tidal exchange, plant dispersal, sediment delivery, and accretion are unknown. Marshes were surveyed for elevation and vegetation by species (n = 12). Surface accretion rates were measured in the Natural marsh and created marshes using feldspar marker horizons (n = 5). Vegetation communities differed among marshes with Spartina patens dominating in the Natural marsh, Typha domingensis dominating low to moderate elevations and Baccharis halimifolia dominating high elevations in the Confined marsh, and Schoenoplectus americanus, which is a desirable species for wildlife, dominating in the Unconfined marsh. The Unconfined marsh accreted more mineral matter than the Natural marsh. Denitrification rates were lower in the Confined marsh than in the Unconfined and Natural marshes. Overall, this study illustrates large differences among marshes related largely to elevation, though containment dykes may also be fostering the colonization of wind-dispersed species, such as Typha domingensis. The Unconfined marsh has higher accretion rates, lower maximum salinities during low water events, and higher denitrification rates than the Confined marsh. Ultimately, these findings show the importance of marsh creation design in facilitating the development of desired ecosystem structure and functions.

Forests fire is the most devastating factor of degradation of the Algerian forest, despite numerous efforts to limit it. Traditional fire prevention and firefighting methods have shown their limitations due to their slowness… , is it therefore useful to adopt new techniques in order to react quickly and effectively. The main objective of this study is to model the «forest fire» risk, in order to produce a risk map, which is indispensable for preventing and informing on fire-vulnerable areas. To achieve this objective, a forest fire risk map was elaborated, on the basis of the scientific methods using geographical information systems and satellite imagery. The adopted approach is an empirical model, involving three parameters controlling the behavior of fire, the topo-morphology of the ground, the combustibility of the vegetation cover and human activity. The study area chosen is one of the most affected areas by this phenomenon (Souk Ahras Mountains). It belongs to the densest forest in Algeria, known for its sensitivity to fire, particularly in relation to its physical conditions (nature of the vegetation cover, climatic conditions (strong Sirocco wind) and socio-economic conditions (high population density).

This article is devoted to current problems of environmental protection. Environmental taxes (payments) are the most effective tools that can be used to regulate relations between the state and polluters, as well as to stimulate polluting enterprises to ecologization their production. Objective. The purpose of the paper is to develop a methodological approach to determining the amount of the environmental tax for emissions of carbon dioxide into the atmosphere. Research methods. The purpose of the research is achieved with the help of general scientific methods (analysis of statistical data, synthesis, generalization) and special methods (collection of information, its processing, conducting analytical work, methods of calculations and justifications). The volumes of carbon dioxide emissions into the atmospheric air were analyzed. Among the methods of conducting analytical work, the comparison method was used - to compare the amount of the environmental tax determined by us for emissions of carbon dioxide into the atmosphere with similar environmental tax rates applied in the European Union. Obtained results. A methodological approach has been developed to determine the amount of the environmental tax for carbon dioxide emissions into the atmosphere. The amount of the environmental tax for carbon dioxide emissions into the atmospheric air is determined by the cost of forest ecosystem services for the absorption of carbon dioxide, the annual costs of enterprises for the ecologization of production, the volume of carbon dioxide emissions into the atmospheric air from stationary and mobile sources in Ukraine, the annual volume of carbon dioxide absorption by forest ecosystems from atmospheric air. Our research is complete and includes both an economic and an ecological component, which characterize the state of atmospheric air pollution with carbon dioxide. Using this methodology, we made calculations and obtained economically justified amounts of environmental tax. In terms of its economic significance, such an ecosystem payment is not a new tax and does not contradict the current legislation of Ukraine. Data for calculations are taken from the real economy in the environmental sphere. The amount of such an environmental tax, obtained on the basis of our methodology, correlates with the amounts of taxes for emissions of carbon dioxide into the atmospheric air, which are currently used in European countries. We received the economically justified amount of the appropriate environmental tax. It is thanks to real statistical data that our obtained indicators

Research methods were chosen due to the need to identify a large number of statistical data. First of all, we collect data from hidden devices using different OSINT methods. This data was compiled using the methods of sectoral and cohort analysis to identify qualifying characteristics, which allowed further grouping and comparison. As a result of the analysis, it was possible to identify the structure of Ukrainian branch banking from the perspective of digitalization, to identify trends in its further development, as well as possible points of growth. The analysis shows that the Ukrainian banking system currently occupies a place with light banking, which is clearly reflected in various indicators associated with the most advanced innovative technologies, and also at the same time ahead of the Some digital light banks have a variety of clear characteristics. One of the current advantages of Ukrainian banking is the high level of integration of banking and third-party services, especially financial and government services. Among the important points that allow us to perform an analysis is the high stability of the Ukrainian banking system, which in the minds of the large-scale invasion of Russia not only did not stop, but rather accelerated the development of wired technology. The analysis allows us to confirm for the first time that the Ukrainian banking system will not fail to provide its diverse clients with a high level of effective comfort with a variety of financial services, and it does not appear in this regard direct from light banking, integrated with light innovative processes and can be supported by the use of clear technological answer to the requirements of the demand side. The results of the classification of Ukrainian banks at the level of digitalization in the same segment of light banking allow us to predict the further development of the national system and reveal the most promising directions for such development , and also give the possibility of prioritizing government regulation of financial markets.
Increased expression of GLUT4, catalase and nitric oxide by a crystalised fraction from ethanolic extracts of oak leaf lettuce and okra seed in C2C12 cell line
Authors: Kaewsrichan Jasadee , Pengnoo Ashara
Published: July 2024

The fractions obtained from low temperature-induced crystallisation of ethanolic extracts of green- and red-oak leaf and okra seed were accounted for total polyphenol content and the DPPH antioxidant activity, resulting in 5.99, 4.44, and 12.35 mg gallic acid equivalent per g sample, and 0.45, 0.35, and 0.99 mg Trolox equivalent per g sample, respectively. Insulin resistance was the result after incubating C2C12 skeletal muscle cells in high glucose DMEM for 20 h. Oxidative stress and inflammation were triggered by re-incubating these resistant cells with insulin. The expression of p-p38 MAPK and NF-B proteins and the NF-B p65 transcription factor activity were enhanced. Such inflammatory protein markers were reduced when the crystalised extracts replaced insulin. Increased catalase activity and NO production were also determined for the incubations using the crystalised extracts. It was suitable to include these vegetables in the daily diets of prediabetic individuals for better management of the patient’s health status by increasing insulin sensitivity and decreasing inflammation.

Aim: Acalculous cholecystitis (AAC) accounts for only 5-10% of cholecystitis cases, primarily studied in intensive care units (ICU) patients. The aim of this study to identify risk factors and clinical presentation of AAC in non-ICU patients. Material and methods: We conducted a literature review using PubMed MeshTerms “acalculous cholecystitis” and searched our institution’s database (2018-2022) for “cholecystitis” and “acalculous cholecystitis,” including patients with histopathological findings. Results: 23 patients met the inclusion criteria. based on histopathology report and diagnosis. The most common co-morbidities were cardiovascular and metabolic syndrome. Abdominal pain was the predominant complaint. Ten patients (50%) presented with elevated CRP, bilirubin, and leukocytosis. No mortality was reported at 30 days. Conclusion: AAC in outpatients is not associated with high mortality, unlike in ICU settings. However, it is more frequent in polymorbid patients with cardiovascular risk factors.
Concurrent primary extranodal marginal zone lymphoma and malakoplakia in the vagina: pearls and pitfalls
Authors: Feltaos Nermeen
Published: July 2024

Primary lymphomas of the female genital tract are rare, representing approximately 1% of extranodal lymphomas. The most common histological subtype is diffuse large B-cell lymphoma, followed by follicular lymphoma. Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) in the female genital tract is rare and usually discovered incidentally. While MALT lymphoma is often linked to infections or autoimmune diseases, its cause in the female genital tract is generally unknown. On the other hand, malakoplakia is a chronic inflammatory condition resulting from an impaired histiocytic response to common bacterial infections. In this report, we present an extremely rare case of concurrent primary MALT lymphoma and malakoplakia in the vagina of a 79-year-old woman who exhibited postmenopausal bleeding and a soft tissue mass. Tissue examination revealed malignant lymphoid cells obscured by abundant inflammatory cells interspersed with numerous blood vessels, mimicking granulation tissue. A significant diagnostic challenge lies initially in missing the concurrent presence of malignant lymphoma and malakoplakia. Therefore, we emphasize the importance of clinicopathological correlation to accurately diagnose these rare conditions.

Authors: Zabielska Izabela , Brudniak Gabriela
Published: July 2024

The main objective of the study is to identify the state of economic relations between Poland and Ukraine since the early 1990s, taking into account mutual trade (also within the framework of the LBT) and Poland’s investment involvement in Ukraine. The study uses a statistical-descriptive method. Based on the analyses, it is concluded that the potential of bilateral economic relations has not been fully exploited so far. Although trade has been developing over the years, it has encountered certain difficulties. The difficult economic situation in Ukraine has become crucial. In light of this conclusion and the currently uncertain geopolitical situation, the realisation of Polish Ukrainian economic cooperation, including trade, in the coming years appears to be closely linked to the reconstruction of Ukraine’s infrastructure.

Published: July 2024

It is known that during the synthesis of superconducting EuRbFe4As4 single crystals, inclusions of its parent EuFe2As2 phase are encountered. The kinetics of the formation of the orthorhombic phase in EuRbFe4As4 crystals containing a large fraction of the EuFe2As2 phase has been studied using polarization optical microscopy. It is shown that the orthorhombic phase grows into the tetragonal one in stripes with the same crystallographic orientation, forming macro-domains. Then these domains abruptly penetrate parallel stripes of the orthorhombic phase of the second orientation, and a twin system of orthorhombic domains is formed. The process is accompanied by the appearance of macrostresses: stretching and compression waves with a characteristic period of 100–300 μm along and across the twin system, leading to spatial modulation of magnetic permeability. It has been found that even weak magnetic fields (up to 100 Oe) significantly affect the spatial distribution of the twin structure and have an effect similar to external stresses.

Authors: Supelnyak S. I. , Artemov V. V.
Published: July 2024

Substrates with a layer of anodized aluminum oxide are obtained by one-stage and two-stage anodization. The samples had different porosity in volume and on the surface. Bismuth nanoparticles were obtained by thermal evaporation in argon by condensation onto substrates with a layer of anodized aluminum oxide. The distribution of sizes, shapes, and numbers of nano- and microparticles was studied using images obtained with a scanning electron microscope. The largest number of nanoparticles (21%) on the sample with a surface layer of aluminum oxide without pores had a diameter of 70 nm. It was assumed that the presence of pores on the surface affected the migration of deposited atoms and particles of bismuth melt until stable condensation centers were formed. The presence of pores with a diameter of 20–100 nm led to a decrease in the diameter of the most common bismuth nanoparticles from 80 to 40 nm. Nanoparticles with a diameter of 90 nm were predominant (25%) in the sample with pores with a diameter of 60–220 nm. The largest number of spherical crystallites on all substrates had a diameter of 110 nm. It was established that a uniform distribution of particles was obtained on a sample, the surface of which was not subjected to chemical polishing.

Published: July 2024

The results of comparative studies of the phase composition, diffuse reflectance spectra, radiation-induced absorption spectra, and the integral absorption coefficient of solar radiation upon irradiation of micro- and nanopowders of gadolinium oxide are presented. To assess the radiation resistance of optical properties, the samples were placed in a chamber of an installation simulating space conditions, where diffuse reflection spectra were recorded in the range of 0.2–2.5 μm in a vacuum of 2×10–6 Torr before and after each period of electron irradiation (E = 30 keV, Φ = (1 – 3)×1016 cm–2). Micropowders of rare earth elements are used to increase the radiation stability of materials by absorbing free electrons formed in them during irradiation during their transitions from the d- to f-shell. Nanopowders of rare earth elements added to micropowders of various compounds provide an additional mechanism for increasing radiation stability due to the annihilation of primary defects formed during irradiation on nanoparticles. The work obtained a result opposite to these mechanisms - the radiation stability of micropowder is significantly (more than 4 times) higher compared to nanopowder, due to more intense absorption in the ultraviolet region for nanopowder, caused by its own defects. The paper gives an explanation of the results obtained.
Features of cluster ion treatment of the surface of KGd(WO4)2:Nd single crystal
Authors: Nikolaev I. V. , Korobeishchikov N. G.
Published: July 2024

The features of the surface treatment of single crystals of potassium gadolinium tungstate doped with neodymium ions with low- and high-energy cluster argon ions are considered. Two radically different treatment modes were used: low-energy for more efficient surface smoothing and high-energy for more efficient target etching. Using atomic force microscopy, the topography of the target surface was analyzed before and after cluster ion treatment. Treatment in a low-energy mode was shown to smooth out irregularities on the target surface formed by chemical-mechanical polishing at an etching depth of less than 100 nm. The root-mean-square roughness and maximum height difference of the initial and treated surfaces of potassium gadolinium tungstate doped with neodymium ions were compared. Survey X-ray photoelectron spectra of the initial surface of a KGd(WO4)2:Nd single crystal and after the cluster ion treatment in different modes are presented. The intensities of the potassium and gadolinium peaks were shown to decrease after cluster ion treatment in both modes. A significant decrease in the concentration of potassium atoms in the subsurface layer of the target is explained by the predominant sputtering of potassium as a lighter chemical element. The mutual decrease in the concentrations of gadolinium and potassium atoms can be explained by the weak bonds of these atoms in the lattice of the KGd(WO4)2:Nd single crystal.
Effects of laser pretreatment on the formation of nanostructured carbon on the surface of chlorinated polyvinyl chloride under high-power ion beam irradiation

The features of formation of surface morphology of chlorinated polyvinyl chloride (pure and with the addition of the catalyst - ferrocene) under the influence of a high-power ion beam of nanosecond duration after the preliminary pulsed laser treatment of the polymer surface have been investigated. It was found that the morphology of the irradiated surface of chlorinated polyvinyl chloride after pulsed laser surface pretreatment differs significantly from the morphology of the irradiated surface of chlorinated polyvinyl chloride after a preliminary stationary heat treatment. For pure chlorinated polyvinyl chloride, pulsed laser pretreatment with increasing power leads to an increase in the porosity of the surface layer after high-power ion beam irradiation, whereas different surface morphologies, including fibers (including polymer fibers) of different diameters, can be obtained for the pre-stationary post-irradiation thermal treatment of this polymer. Pre-stationary thermal pretreatment of chlorinated polyvinyl chloride with the addition of ferrocene (Fe(C5H5)2) leads to a decrease in the diameter of formed carbon nanofibers (with an increase in the treatment temperature). During the pulsed laser pretreatment, an increase in the porosity of the treated layer and a slight increase in the proportion of nanofibers of larger diameter are observed. To explain the obtained differences for pulsed laser and stationary thermal pretreatment, the effect of polymer heating rate on the features of chlorinated polyvinyl chloride decomposition was analyzed.

Purpose: individualization of the use of immune checkpoint inhibitors in patients with inoperable NSCLC potentially sensitive to immunotherapy based on the level of the combined expression index as a predictive marker of effectiveness.Methods: in 146 patients with inoperable NSCLC, the level of the combined expression index in a tumor tissue sample was determined using PCR, which included studies of ten genes (CCL5, CXCL9, CXCR6, HLA-DQA1, TIGIT, EOMES, CTLA4, PD-L2, GZMB, PRF1). The patients were divided into cohorts depending on the level of the combined expression index and randomized into chemotherapy or immunotherapy groups. The null hypothesis of the study was that the group with a low combined expression index would have a 6-month progression-free survival of 35%, and with a high combined expression index – 75%, with α-error probability of 0.05, a power of 90%. Results: the use immune checkpoint inhibitors in the first line of the therapy for patients with a high level of the combined expression index leads to a significant increase in the rate of objective responses from 18% to 43%, the median overall survival from 10 to 21 months, and the median time to progression from 7.3 to 14.8 months. The 6-month progression-free survival rate in the group with a high combined expression index was 79%, versus 35% in the group with a low combined expression index. Conclusion: analysis of the gene expression signature can become one of the reliable predictive markers that predict the real effectiveness of therapy with immune checkpoint inhibitors, which will improve the results of treatment of patients with unresectable or metastatic NSCLC. Key words: NSCLC, immune checkpoint inhibitors, gene expression signature, predictive markers

This service is carried out at the Sukahaji Mandiri Community Food Barn (LPM). This service is one of the efforts for orderly administration in farmer groups with the aim of farmer groups understanding the benefits of administration, various types of administration and the steps for making group administration. This service activity was carried out on Thursday, January 27, 2022. Most of the income of the people of Sukahaji Village, Majalengka Regency, was obtained from rice farming. The role of farmer groups has an important role in improving the welfare of farmers, especially related to income. This is inseparable from the efforts made by the group in protecting its members. The success of a farmer group is reflected in the ability of administrative management. So this certainly plays an important role in the sustainability of farmer groups further in increasing group productivity. The services that have been carried out provide understanding and ability to manage administration, including the creation of member books, group activity books, guest books, meeting minutes, agenda books for incoming and outgoing letters, management books and financial administration.
