“It’s an ongoing process”: A qualitative analysis of men's feminist identity growth
Authors: Siegel Jaclyn Amanda , Elbe Connor , Calogero Rachel
Published: January 2022

Feminist identity is a powerful predictor of engagement in gender-based activism. Men's feminist identification is complicated by the uniquely gendered stereotypes attributed to feminist men, which are antithetical to traditional masculine gender role norms. While there is a substantial body of literature surrounding the feminist identity development process in cisgender women, research exploring men’s feminist identity development is scant. This study aimed to develop a more comprehensive understanding of men’s feminist identity development in the context of masculine gender role norms. Twenty-seven cisgender, feminist-identified men (Mage = 33.08, SD = 8.42) recruited via social media were interviewed for the study. Through reflexive thematic analysis, the authors extracted five themes from the data: Diverse Feminist Foundations, Turning Points, Evaluation and (Un)Learning, Taking Action, and Feedback. The men described a feminist identity growth process that was complex and ongoing, catalyzed by various moments of dissonance and clarity throughout their lives. They articulated their negotiation of traditional masculinity, embracing the parts that supported their growth and rejecting aspects that were inconsistent with their feminist principles. Men also shared their unique and creative ways of practicing and promoting feminism as well as the feedback they received for doing so. We conclude with suggestions for men who wish to support gender equality and the feminist women who wish to support men's feminist identity growth.
ETHICAL SUPPLY CHAIN FOR MINERAL ORES IN DEMOCRATIC REPUBLIC OF CONGO USING BLOCKCHAIN TECHNOLOGY
Authors: Mirera Kevin Muriithi
Published: January 2022

T he Democratic Republic of Congo in short DRC which has been blessed with a flurry of minerals has been suffering from the paradoxical “resource curse” showing worse economic development than countries with fewer resources, this has been due to weak democratic development, corruption, and civil war. Increased levels of corruption in the mining sector resulted in great political instability because whoever controls the assets usually those with political might use them for their own benefit, the increase in importance of minerals like cobalt and coltan due to the ubiquity and necessity of mobile phones which heavily rely on these materials has resulted in warlords and armies in DRC converting ASMs (Artisan and small miners) into slave laborers, soaring prices of materials like coltan are said to have brought militias more than 20 million dollars (about twice the cost of a celebrity mansion) a month. With increasing demand from buyers to purchase ethically sourced materials there is an increasing need to reform the mining industry in DRC and one of the propositions is through ethical supply chain management using blockchain technology. One of the major benefits of blockchain technology is accountability according to UN surveys military occupation by Ugandan and Rwandese soldiers plus other foreign military forces as well as many bands of Congo military factions fighting there was massive looting of Congolese natural resources and the fighters were enriching themselves by mining and smuggling out coltan, Copper, gold, diamonds etc. This could have been averted if there was an accountability measure in the purchase and resale of these materials that is in the supply chain of these ores. Accountability or lack thereof which has led to unspeakable evils like slave labor is not the only malevolent act that has been a result of these mining expeditions soil erosion and other environmental concerns like pollution of rivers and the increasing reduction of eastern mountain gorillas is just another example. This paper will talk about how blockchain can be integrated into this supply chain network to enhance traceability, increase efficiency and speed of supply, improve financing, contracting, and international transactions and how a workable technology can be created.
A brief history and indications for cesarean section
Authors: Dhakal-Rai Sulochana , Van Teijlingen Edwin , Regmi Pramod R , Wood Juliet , Dangal Ganesh , Dhakal Keshar Bahadur
Published: January 2022

Cesarean section (CS) is one of the oldest surgical operations. Originally, this surgery was performed post-mortem by cutting open the woman’s abdomen to remove a dead or alive fetus. It was therefore not intended for saving the mother in ancient times. Roman law and religious rituals shaped the procedure until the Middle Ages. At that time, the indication of CS was only post-mortem. Although CS became a medical procedure in the Renaissance, maternal mortality was extremely high, mainly due to hemorrhage and puerperal infection. The reason for performing CS was to rescue the mother and fetus from protracted labor as a last resort. Since the late 19th century, with the introduction of chloroform and the developments of surgical techniques, and the availability of blood transfusion in the early twentieth century, CS became a relatively safe procedure, further helped by the introduction of antibiotics after World War II. Then, CS was increasingly an intervention to preserve the health and safety of both mother and fetus. During the 21st century, CS has been performed even without medical indication, such as maternal choice. Advancement of obstetric practice technologically and professionally during the period as well as changing attitudes of both obstetricians and childbearing women meant indications for CS are no longer limited to medical/obstetric indications. CS is perceived as a safer mode of childbirth.  Therefore, the indications of CS have been changed drastically from ancient times (rescuing a baby from dying or dead mother) to the 21st century (maternal choice/reproductive rights).

INFLUENCE OF VEGETATION ON SOIL CARBON STOCKS IN FORESTS (REVIEW)
Authors:   Center for Forest Ecology and Productivity of the Russian Academy of Sciences, Kuznetsovа A. I.
Published: January 2022

Existing estimates of carbon stocks in taiga and coniferous-deciduous forests show that almost half of the total organic carbon in these ecosystems is accumulated in forest soils. Vegetation as the main source of organic matter in the soil, interact with soil biota, which processes plant litter, and with abiotic environmental factors, determines the processes of formation and accumulation of soil organic matter. Changes in the composition of vegetation are the driver of the dynamics of soil carbon stocks; however, insufficient attention has been paid to the analysis of this issue. The review analyzes the main ways of transferring carbon from the vegetation pool to the soil pool and the influence of three main predictors of vegetation that affect the carbon stock in soils: the amount and quality of litter of individual species (species identity) of plants and the structural diversity of the plant community; gaps in knowledge and the ways of development of this scientific direction are proposed.

Published: January 2022

Study Objective: To assess the prevalence and association between androgenic deficit and hyperuricemia in men with normal weight, overweight, and obesity. Study Design: single-site retrospective study. Materials and Methods. We retrospectively analysed 301 medical records of patients examined by a thyroid specialist, and collected information on their height, weight, age, uric acid (UA) levels (283 patients) and testosterone (301 patients). All information was entered into a single database. Study Results. Testosterone deficit was found in 57.5% of subjects; the testosterone level significantly dropped with an increase in the body mass index (BMI) — from 13.74 ± 0.76 (4.66) nmol/L in patients with normal BMI to 8.65 ± 0.53 (2.76) nmol/L in patients with stage 3 obesity (р < 0.01). Hyperuricemia was found in 30.7% of subjects; the UA level significantly rose with an increase in BMI — from 359 ± 11 (66) μmol/L in patients with normal BMI to 440 ± 16 (80) μmol/L in patients with stage 3 obesity (р < 0.01). A combination of testosterone deficit and hyperuricemia was recorded in 66 (23.3%) out of 283 subjects. Conclusion. There is a clear correlation between a lower testosterone level and increased UA concentration. It is difficult to name a clear pathogenic cause of this fact; most probably it is an excessive adipose tissue which affects aromatase and purine exchange in general. Keywords: testosterone deficit, hyperuricemia, obesity, uric acid.

Published: January 2022

OBJECTIVE

The clinical response of patients with bipolar disorder to medical treatment is variable. A better understanding of the underlying neural circuitry involved in bipolar treatment responsivity subtypes may provide insight into treatment resistance and aid in identifying an effective surgical target for deep brain stimulation (DBS) specific to the disorder. Despite considerable imaging research related to the disease, a paucity of comparative imaging analyses of treatment responsiveness exists. There are also no DBS targets designed expressly for patients with bipolar disorder. Therefore, the authors analyzed cingulum bundle axonal connectivity in relation to cortico-striatal-thalamo-cortical (CSTC) loops implicated in bipolar disorder across subjects who are responsive to treatment (RSP) and those who are refractory to therapy (REF), compared to healthy controls (HCs).

METHODS

Twenty-five subjects with bipolar disorder (13 RSP and 12 REF), diagnosed using the Mini International Neuropsychiatric Interview and classified with standardized rating scales, and 14 HCs underwent MRI with diffusion sequences for probabilistic diffusion-weighted tractography analysis. Image processing and tractography were performed using MRTrix. Region of interest (ROI) masks were created manually for 10 anterior cingulum bundle subregions, including surgical targets previously evaluated for the treatment of bipolar disorder (cingulotomy and subgenual cingulate DBS targets). Cortical and subcortical ROIs of brain areas thought to be associated with bipolar disorder and described in animal tract-tracing models were created via FreeSurfer. The number of axonal projections from the cingulum bundle subregion ROIs to cortical/subcortical ROIs for each group was compared.

RESULTS

Significant differences were found across groups involving cingulum bundle and CSTC loops. Subjects in the RSP group had increased connections from rostral cingulum bundle to medial orbitofrontal cortex, which is part of the limbic CSTC loop, whereas subjects in the REF group had increased connectivity from rostral cingulum bundle to thalamus. Additionally, compared to HCs, both RSP and REF subjects had decreased cingulum bundle dorsal connectivity (dorsal anterior/posterior cingulate, dorsomedial/lateral frontal cortex) and increased cingulum bundle ventral connectivity (subgenual cingulate, frontal pole, lateral orbitofrontal cortex) involving limbic and associative CSTC loops.

CONCLUSIONS

Findings demonstrate that bipolar treatment responsivity may be associated with significant differences in cingulum bundle connectivity in relation to CSTC loops, which may help identify a surgical target for bipolar disorder treatment via DBS in the future.

OBJECTIVE

In this article, the authors describe the impact of the COVID-19 virtual match cycle and discuss approaches to optimize future cycles through applicant and neurosurgical education leadership insights.

METHODS

Anonymous surveys of neurosurgery program leaders (program directors and program chairs), program administrators (PAs), and 2020–2021 neurosurgery residency match applicants were distributed by the SNS, in conjunction with the Association of Resident Administrators in Neurological Surgery and AANS Young Neurosurgeons Committee.

RESULTS

Responses were received from 77 (67.0%) of 115 PAs, 119 (51.7%) of 230 program leaders, and 124 (44.3%) of 280 applicants representing geographically diverse regions. During the virtual application cycle relative to the previous year, programs received more Electronic Residency Application Service applications (mean 314.8 vs 285.3, p < 0.0001) and conducted more applicant interviews (mean 45.2 vs 39.9, p = 0.0003). More than 50% of applicants applied to > 80 programs; 60.3% received ≤ 20 interview invitations, and 9% received > 40 invitations. Overall, 65% of applicants completed ≤ 20 interviews, whereas 34.7% completed > 20 interviews. Program leaders described one 4-week home subinternship (93.3%) and two 4-week external subinternships (68.9%) as optimal neurosurgical exposure; 62.8% of program leaders found the standardized letter of recommendation template to be somewhat (47.5%) or significantly (15.3%) helpful. Applicants, PAs, and program leaders all strongly preferred a hybrid model of in-person and virtual interview options for future application cycles over all in-person or all virtual options. Ninety-three percent of applicants reported matching within their top 10–ranked programs, and 52.9% of programs matched residents within the same decile ranking as in previous years.

CONCLUSIONS

Optimizing a national strategy for the neurosurgery application process that prioritizes equity and reduces costs, while ensuring adequate exposure for applicants to gain educational opportunities and evaluate programs, is critical to maintain a successful training system.

Published: January 2022

OBJECTIVE

Recent MR vessel wall imaging studies of unruptured intracranial aneurysms (UIAs) have revealed that aneurysm wall enhancement (AWE) can be an indicator for aneurysm evolution; however, the degree of AWE among different types of evolving UIAs has yet to be clarified. The authors assessed the degree of AWE in unruptured posterior communicating artery (PcomA) aneurysms with oculomotor nerve palsy (ONP), which may be a subgroup of evolving UIAs with rapid enlargement and high rupture risk.

METHODS

The degree of AWE was analyzed in 35 consecutive evolving PcomA aneurysms (19 with and 16 without ONP). UIAs were considered to be evolving when showing growth or ONP. A 3D T1-weighted fast spin echo sequence was obtained after contrast media injection, and the contrast ratio of the aneurysm wall against the pituitary stalk (CRstalk) was calculated as the indicator of AWE. The CRstalk in evolving UIAs with ONP was compared with that in UIAs without ONP.

RESULTS

The CRstalk was significantly higher in evolving UIAs with ONP than in those without ONP (0.85 vs 0.57; p = 0.006). In multivariable analysis, the CRstalk remained a significant indicator for ONP presentation in evolving UIAs (OR 6.13, 95% CI 1.21–31.06).

CONCLUSIONS

AWE was stronger in evolving PcomA aneurysms with ONP than in those without ONP, suggesting the potential utility of AWE for risk stratification in evolving UIAs. The degree of AWE can be a promising indicator of a rupture-prone UIA, which can be useful information for the decision-making process in the treatment of UIAs.
Enhancing English in Ecuador: Exploring Korean English Educational Policy Innovations
Authors: Espinar Chriselle Domenica
Published: January 2022

Ecuador requires the incorporation of new educational policies that meet the needs of English in today's society. One of the strategies required to solve this problem is to develop alongside international educational trends. This article explores the proposals in the teaching of the English language within the educational system of South Korea such as the EPIK and FSP, showing alternatives that may become applicable in the Ecuadorian context. This review is qualitative, exploratory and descriptive in scope. Information related to the needs and challenges faced by EFL contexts was recovered and organized into three main sections: (1); Specific needs of the teaching- learning of English, (2); What about teaching English in South Korea? (3); Challenges of the EFL Context. It was agreed that in Ecuador and Korea, students feel great difficulty developing productive skills (speaking / writing). Further research can take this article as a reference of the successes and challenges of EFL contexts to create more policies that can be implemented in such a way that schools, government and teachers are encouraged to take advantage of the variety of opportunities and overcome the challenges.

The global environmental awareness and regulatory process has covered a trajectory of 50 years. From the innocent times of the first 1972 UN Conference on the Human Environment (UNCHE), the world has travelled very far. It has encompassed a veritable process comprising role of actors, polarizing issues such as balancing of environment-development, emergence of norms and governance forms. In the post-Westphalian governance order, the political landscape has been a determining factor for the contemporary environmental discourse. Even as the global governance architecture has become more complex and hierarchical, what can UNCHE + 50 ordain for our environmental future? What alternatives are possible for survival of the planet earth and betterment of the humankind? This article seeks to examine some of these issues of environmental politics that will determine the future course of action at UNCHE+50 event in June 2022 and beyond.
Exploring curcumin interactions with BN nanostructures: A DFT approach
Authors: Jalil Abduladheem Turki , Altimari Usama S. , Ansari Mohammad Javed , Mohamadi Akram
Published: January 2022

Density functional theory (DFT) calculations were performed to investigate the curcumin adsorption at the surfaces of two boron nitride (BN) nanostructures including nanosheet (BNNS) and nanotube (BNNT). The singular models were optimized to reach the stabilized structures and to evaluate electronic features. Next, performing optimization processes on interacting systems yielded formations of bimolecular complexes through occurrence of physical interactions. For curcumin, keto and enol tautomeric forms were investigated for participating in interactions with the BN nanostructures, in which the enol form was seen for participating in stronger interactions with both of BNNS and BNNT surfaces in comparison with the keto form. Based on such interactions, electronic molecular orbital features detected the effects of molecular communications to show benefit of employing BN nanostructures for drug delivery purposes. Moreover, BNNS was seen to work better than BNNT for such purpose of adsorption and detection of curcumin substance.

Authors:   Donbass State Engineering Academy, Avdeenko A.P. , Baklanov O.M. , Konovalova S.O. , Khmars'ka L.O. , Baklanova L.V.
Published: January 2022

To intensify the dry mineralization of foodstuffs, the use of ultrahigh-frequency ultrasound in combination with treatment by gaseous oxidants (chlorine or nitrogen oxides) has been proposed. The optimal parameters of ultrasound were experimentally established as follows: frequency of 11.0–14.0 MHz, power density of 17.0–19.0 W/cm2, and process temperature of 60–650С. Under these conditions, the degree of lead and cadmium extraction during mineralization of different food groups was 94.5–98.1% and 96.7–99.0%, respectively. Due to the exclusion of sample processing in the muffle furnace, the number of stages in sample preparation was reduced from three to two, which led to an increase in the rapidity of mineralization by 12–14 times and better metrological characteristics of food analysis results.

The influence of component composition and the nature of plasticizer on the features of intermolecular interactions in the system poly(vinyl chloride)–polystyrene–diester phthalate was established. It was found that polystyrene macromolecules are actively involved in interactions with both poly(vinyl chloride) macromolecules and plasticizer molecules, forming associates of slightly smaller size. It was noted that the wetting angle of the surface by plasticizer and the work of adhesion largely depend on the nature of a plasticizer and a polymer dissolved in it. This indicates a significant effect of the nature and content of the polymer modifier on the compatibility of poly(vinyl chloride) and plasticizer and changes in thermodynamic characteristics of the system. The influence of the nature and content of polystyrene modifier on physicochemical features of the migration process of diester phthalate plasticizer from modified poly(vinyl chloride) plasticate as well as on its morphological features was studied. It was found that the thermodynamic compatibility of the components is significantly affected by the wettability of the surface of fine polymer particles with liquid plasticizers, which, in turn, affects the release (migration) of the plasticizer from poly(vinyl chloride) plastics during operation of products based on them. Pre-dissolution of suspension polystyrene or acrylonitrile butadiene styrene plastic in the plasticizer, regardless of its nature, leads to a significant reduction in the value of migration.

The thermodynamics of the alkaline leaching of ilmenite was investigated in this work. Thermodynamic parameters (enthalpy, entropy, Gibbs energy, etc.) are important and necessary for understanding both the course of the chemical reaction as a whole and the possibility of its implementation in the production process. The change in Gibbs energies at different temperatures during the chemical reaction of ilmenite leaching was calculated by the Temkin-Schwartzman method. The calculated values of the Gibbs energies of the reactions for the production of sodium and potassium titanates allowed us to state that the interaction of ilmenite with potassium hydroxide is energetically more advantageous. With the help of X-ray diffraction studies, it was established that ilmenite from the Irshansky deposit is leukoxenized. The identification of the main reflexes of the diffraction patterns confirmed that the interaction of potassium hydroxide and ilmenite yields potassium titanate.

New coordination compounds of a-phenyl-N-methylnitrone with Cu2+, Mn2+, Ni2+, and UO22+ were synthesized. Complexes were studied by means of IR, NMR and UV-Vis spectroscopies. The crystal and molecular structure of uranyl complex with a-phenyl-N-methylnitrone was determined by X-ray diffraction study. The monodentate nitrone ligands are coordinated to the metal ion via oxygen atom. The coordination polyhedron of uranium is a distorted hexagonal bipyramide. It was shown that there is dynamic process in the acetone solution in the temperature range of 203–297 K. The ligand exists as a trans-isomer for both present forms of organic ligand by the NOE difference. Dimeric copper(II) benzoate was obtained via recrystallization of the copper complex with a-phenyl-N-methylnitrone from methanol solution. According to X-ray diffraction analysis, the environment of each of the copper atoms is octahedral. The coordination sphere is formed by six oxygen atoms. Three anions of benzoic acid are coordinated bidentate-bridged through oxygen atoms of the carboxyl group, while one molecule of benzoic acid is coordinated monodentatically through the carboxyl oxygen atom.
Hydrogen Economy as a Driver of Synergetic Technological Development: Policy and Application Evidence from Russia
Authors: Salnikova Anastaisa
Published: January 2022

Hydrogen energy is still at an early stage of development: Nevertheless, national and international strategies are used to boost its development by all kinds of incentives, subsidies, tax instruments and R&D financing of pilot projects in order to achieve the main goals: decarbonization of the energy sector, ensuring the reliability of supply of energy systems. The technical capabilities of decarbonization are still coexisting with high production costs, difficulties in storing and delivering hydrogen to consumers. Shift to hydrogen economy is not possible without thorough consideration of policies at different levels as well as technological advances. In this article the author analyses current situation of Russian hydrogen economics from strategic and technological point of view. The main agenda-setting documents and contributors in the field of technical deployment of hydrogen projects have been analyzed by applying content-analysis. Main policy implications and recommendations have also been given.
Analysis of the Existence of Environmental Kuznets Curve: Evidence from India
Authors: Gopakumar Goapl , Jaiswal Ritika , Parashar Mayank
Published: January 2022

The study aims to estimate the Environmental Kuznets Curve (EKC) in the Indian context for the period of 1991-2018 by considering the role of economic growth, renewable energy, foreign direct investment, stock market size, energy intensity, and private investment in the energy sector with the help of autoregressive distributed lag (ARDL) cointegration technique. The results confirm the existence of an inverted U-shaped EKC relationship between economic growth and CO2 emission level. However, the estimation of turnaround point shows that CO2 levels have kept increasing past the turnaround point, indicating that income disparity is a decisive factor in determining emissions and is a better indicator than national income. Furthermore, results confirm the negative impact of economic growth and stock market size on the environment. In contrast, renewable energy, foreign direct investment, and energy intensity positively impact the environment in the long run. However, the impact of private investment is insignificant. Though the Indian economy continued to grow during the last few decades, the minimal investment towards renewable energy may not help to reduce the environmental problems. Hence, the nation's income growth alone does not solve the ecological issues in the long run. In addition, it requires an increase in private investment towards the development of India's renewable energy sector.

Сестринский уход за больным с диабетическая стопа
Authors: Cunha Amanda Priscilla da
Published: January 2022

Введение: Диабетическая стопа, также называемая многогранным патофизиологическим состоянием, характеризуется поражениями, которые возникают из стоп человека с сахарным диабетом без адекватного лечения и специфического ухода. Подсчитано, что заболеваемость диабетической язвой стопы достигает 6,3% больных сахарным диабетом и ее распространенность приближается к 10%, а наибольшими жертвами являются люди с низким социально-экономическим статусом. С учетом этих доказательств работа основана на следующем проблемном вопросе: Какую помощь развивает медсестры у пациентов с диабетическая стопа? Общая цель: Доказать уход за диабетическая стопа, связанный с практикой медсестер. Методология: Интегративный обзор был проведен в Специализированной библиографической базе данных по сестринскому делу (BDENF), латиноамериканской и карибской литературе по наукам о здоровье (LILACS) и Научной электронной библиотеке онлайн (SCIELO), в результате чего было подготовлено семь статей. Результаты: Исследования показали, как осуществляется уход за медсестрами с диабетическая стопа, санитарное просвещение, непрерывное и постоянное образование, методы оценки диабетическая стопа, которые включают физические осмотры и самообслуживание пациентов с диабетической стопой. Подчеркивается, что этот уход должен осуществляться в приоритетном порядке медсестрами, поскольку медсестры имеют конкретную и квалифицированную помощь пациенту в своих основных атрибутах. Вывод: Таким образом, делается вывод о том, что исследование выявило несколько форм ухода, предоставляемого медсестрами, и что все эти формы важны для непрерывности лечения и профилактики осложнений, однако медсестра должна быть профессионалом, который ценит качество своего ухода, основываясь на теоретических концепциях, которые приводят к частому обучению.

Published: January 2022

Background: People living with HIV (PLHIV) have a higher incidence of cardiovascular disease and complications after intervention, including in-stent thrombosis. The frequency of potential drug-drug interactions in the setting of acute coronary syndrome (ACS) with antiretroviral therapy (ART) and dual-antiplatelet therapy (DAPT) regimens remains unclear. We sought to determine the frequency of potential drug-drug interactions in a cohort of people living with HIV who were investigated for coronary disease and initiated on DAPT as per Australian ACS Guidelines. Methods: A retrospective audit was performed in a single tertiary hospital in PLHIV presenting with symptomatic coronary artery disease (CAD) receiving DAPT. Patients were grouped based on exposure to a protease inhibitor or efavirenz and etravirine, given that these were found to have the greatest potential interactions with DAPT. Results: Fifty-three patients received DAPT, of which 31 (58%) had a potential drug-drug interaction. Clopidogrel was the most frequent P2Y12 inhibitor prescribed, accounting for 47 (87%) of the interactions. Twenty-six patients were on a protease inhibitor, of which 21 (81%) had a potential drug-drug interaction. There were 11 instances of efavirenz and 3 of etravirine use, of which all resulted in potential drug-drug interactions (100%, respectively). Conclusion: Potential drug-drug interactions were very common in PLHIV needing DAPT. The widespread use of clopidogrel in DAPT regimens resulted in a high rate of drug-drug interactions. An awareness of interactions and guidelines around P2Y12 inhibitor selection may help reduce the rate of in-stent thrombosis for PLHIV and improve clinical outcomes.
