Published: July 2024

Since there are blind and partially sighted people all over the world, they face significant challenges when it comes to reading. In the past, Braille was the only solution for the blind and visually impaired to read and learn. However, there is a lack of training in Braille and a shortage of Braille machines and facilities. To address these issues, a smart reader for the blind integrated with Raspberry Pi technology has been proposed. The system utilizes YOLO (You only look once) for object detection, OCR (Optical Character Reader) for text recognition, and Google Text-to-Speech to capture and read text aloud through a speaker or headphone. Smart glasses offer real-time assistance and enhance the daily lives of visually impaired individuals. Through a combination of sensors, cameras, and audio feedback systems, these smart glasses enhance the reading capability of the visual impaired. Moreover, advancements in artificial intelligence and Deep learning algorithms further enhance the capabilities of these devices, enabling more accurate personalized assistance.

INHIBITION PROPERTIES OF CLINICALLY IMPORTANT ENZYMES IN WOUND HEALING BY BEE VENOM
Authors: Keskin M , Keskin S , Karlidag S
Published: July 2024

Apitherapy has importance in traditional and complementary medicine practices, including applications made by directly or functionalizing honey, pollen, propolis, bee venom, and bee bread (perga) obtained from honey bee colonies. Bee venom is preferred by apitherapists and is directly applied to the body from the bee sting or used in crystalline form. Apitoxin is a product that is formed in the venom bag of bees and contains mainly apamin, melittin, MCD-peptide, hyaluronidase, histamine, and phospholipase A2. Due to its these active ingredients, bee venom is effective in arthritis, central and peripheral nervous system diseases, respiratory diseases, gastroenterology, cardiovascular system diseases, eye diseases, skin diseases, urology, endocrinology, cancer diseases, and using it in the cosmetics industry is very popular. Although bee venom is widely used directly or indirectly in apitherapy applications, it is not possible to use standardized bee venom as a drug. In this study, the amount of total protein, melittin, and phospholipase A2 amounts of bee venom samples were determined and their inhibition effects on collagenase and myeloperoxidase enzymes were examined. The mean amounts of phospholipase A2, apamin, and melittin contained in bee venom samples were found to be 46.38%±0.10%, 2.19±0.11%, and 12.46±0.19%, respectively. It was determined that bee venom samples inhibited the collagenase enzyme by more than 50%. It shows that bee venom has an inhibitory effect on clinically important enzymes. However, it is necessary to conduct allergy tests before the use of the bee venom directly.

Authors: Chemerys Maryana , Markova Marianna
Published: July 2024

The purpose of the work is to analyze the presence, variability and intensity of sleep disturbances in patients with diffuse alopecia, in order to create, in the future, differentiated and individualized approaches to the management of this category of patients. 153 women aged 25 to 45 with diffuse alopecia were examined. With the help of a structured interview according to the ICD-10 criteria and the use of a psychodiagnostic method, three groups were distinguished among patients: without signs of mental maladjustment (MM), numbering 45 people, with separate signs of maladjustment, numbering 73 people, and with the presence of adaptation disorders, respectively to the criteria of ICD-10, numbering 35 people. Within each of these groups, two subgroups were distinguished, taking into account the genesis of alopecia: metabolic (45 patients) or mixed (108 patients). It was established that in the structure of psychosomatic clinical manifestations of the pathological trichological process in patients with diffuse alopecia, the entire variable spectrum of clinical dyssomnia symptoms is found — early, middle, late dyssomnias, nightmares and lack of rest after waking up — the prevalence and intensity of which are associated with the genesis of dermatological pathology (metabolic or mixed forms of alopecia). Among patients with a mixed form of diffuse alopecia, psychosomatic dyssomnic manifestations have a significantly greater representation and severity than among patients with metabolic alopecia, which is confirmed by the presence of statistically significant differences.

Authors: Asbi Shinta , Indra Ihsan  , Rinang Mariko
Published: July 2024

Background: Dengue shock syndrome (DSS) is a life-threatening complication of dengue infection characterized by plasma leakage, shock, and organ dysfunction. Fluid management is crucial in DSS, but fluid overload can lead to adverse outcomes. This case report highlights the challenges and strategies in managing DSS with fluid overload.
Case presentation: An 8-year-old girl presented with severe dengue, DSS, encephalopathy, and fluid overload. She had a history of high fever, vomiting, and altered consciousness. Initial management focused on fluid resuscitation, but the patient developed signs of fluid overload. Hemodynamic monitoring using USCOM (Ultrasonic Cardiac Output Monitor) revealed low cardiac output and high systemic vascular resistance. Fluid restriction and inotropic support with epinephrine were initiated. The patient's condition gradually improved, and she was discharged after complete recovery.
Conclusion: This case emphasizes the importance of early recognition and careful monitoring of fluid status in DSS. Hemodynamic monitoring tools like USCOM can aid in guiding fluid management and identifying complications like fluid overload. Prompt intervention with fluid restriction and inotropic support can improve outcomes in DSS patients with fluid overload.

Authors: Krasovskyi Vadym
Published: July 2024

This article examines intergovernmental cooperation within the framework of the Base Erosion and Profit Shifting (BEPS) Action Plan, developed by the Organisation for Economic Co-operation and Development (OECD) at the initiative of the G20 countries. The relevance of implementing and studying this mechanism is driven by the issues of tax base erosion and profit shifting, carried out by individuals, legal entities, and large multinational corporations, leading to significant annual tax revenue losses, according to the OECD data. The study explores tools to combat this phenomenon. The analysis also focuses on Ukraine’s steps in implementing reforms aimed at joining global efforts to combat tax evasion. The research highlights the challenges facing Ukraine in aligning its tax system with international standards and describes legislative measures taken to counter BEPS. Special attention is given to the adoption of the Multilateral Instrument (MLI) and amendments to Ukraine’s Tax Legislation as key steps towards achieving tax transparency and preventing profit shifting. Furthermore, the study underscores the importance of further research in this field, emphasizing the expansion of international cooperation on tax matters. In the context of Ukraine’s implementation of tax reforms, there is a need for further scholarly exploration to assess policy effectiveness and develop future reforms. The author emphasizes that comprehensive research on the BEPS phenomenon and the implementation of relevant measures are crucial for Ukraine’s integration into the global tax administration system, which is also necessary in terms of Ukraine’s aspirations to join the EU. The author calls for continuous scholarly work to support reforms, promote transparency, and prevent tax evasion both domestically and internationally.

Background. Hemorrhagic transformation (HT) is a serious complication that can arise in individuals experiencing acute ischemic stroke (AIS), whether it occurs spontaneously or following thrombolytic therapy, resulting in considerable morbidity and mortality. Hemorrhagic changes are associated with several risk factors, including excessive blood sugar levels, hypertension, the severity of a stroke, and reperfusion. Aim. To assess the commonly available blood parameters such as lipid profile, serum magnesium, and serum ferritin as tools to identify patients who are at risk of hemorrhagic transformation after an acute ischemic stroke. Materials and methods. The study was conducted at the Saveetha Medical College, Chennai, Tamil Nadu, in India, as a cross-sectional study, and a total of 142 patients diagnosed with acute ischemic stroke were enrolled for this study from January 2023 to January 2024. Results. Among the 32 patients who had a hemorrhagic transformation, all 32 (100%) patients had elevated serum ferritin levels and the remaining 110 patients who had no hemorrhagic transformation were found to have normal serum ferritin levels and the difference was statically significant (p<0.001). Total cholesterol, serum LDL, serum HDL, and serum triglycerides had no statistically significant association with hemorrhagic transformation among the patients. Conclusion. The present study concludes that people with lower serum magnesium on admission and higher serum ferritin were found to be at risk. Serum lipid profile had no statistically significant association with hemorrhagic transformation among the patients.

Bladder cancer (BC) is the predominant malignant neoplasm in the urinary system and ranks as the tenth most prevalent malignant tumor worldwide. Compared with females, males displayed a four-fold more common incidence of bladder cancer. It mainly affects men. Bladder cancer is the fourth most prevalent neoplasm in males. The most important protein that makes up high density lipoprotein (HDL), ApoA-I apolipoprotein A1 is essential in regulating the right amount of cholesterol. Multiple inquiries have demonstrated that APOA1 plays a pivotal role in the progression, infiltration, and spread of tumors. Objectives. The objective of this study was to measure the level of urine to serum apolipoprotein A1 in patients suffering from bladder cancer and investigate the impact of variations to this nanotechnology on the development of the cancer. Material and methods. The study collected 45 blood and urine samples from individuals diagnosed with bladder cancer at Ghazi Hariri Hospital for Specialized Surgery. The samples included both males and females of various ages (61.47±11.28 years). Additionally, 45 blood and urine samples were collected from individuals without the disease. The samples were analyzed using an ELISA method to measure the levels of apolipoprotein A1 in the serum and urine of both groups, and the data collection period spanned from January 2023 to June 2023. Result. The average levels of serum and urine apolipoprotein A1 in the patients' group (14.18±2.62ng/ml, 20.04±4.67ng/ml) were significantly higher than the average levels in the control group (8.21±1.35, 8.94±1.74), with p-values of <0.001 and ≤0.001, respectively. The blood concentration of apolipoprotein A1 showed a significant positive moderate connection with the concentration of apolipoprotein A1 in urine (r=0.45, p<0.001). Conclusion. The mean and SD of serum apolipoprotein A1 in the patients group were higher than control group and urine apolipoprotein A1 in the patients group were higher than control group can be utilized as biomarkers for detecting bladder cancer. However, urine apolipoprotein A1 is a superior biomarker compared to serum apolipoprotein A1 due to its association with several other diseases.

Published: July 2024

This case report emphasizes central retinal vein occlusion (CRVO) as the primary cause of blindness, typically linked to impaired retinal venous drainage from critical vein obstruction. While conditions like diabetes and hypertension are known risk factors for CRVO, rare instances associate it with inflammatory bowel disease (IBD). Here, a 19-year-old male initially presented with painless vision loss, revealing ocular ischemia secondary to panuveitis and moderate CRVO. Genetic testing indicated HLA-B51/B52, suggesting Behcet's disease initially, treated with immunosuppressants and steroids. Despite initial recovery, severe gastrointestinal symptoms later led to ulcerative colitis diagnosis. This sequence highlights CRVO preceding IBD symptoms in a high-risk individual, prompting caution in its differential diagnosis, especially in younger patients without typical risk factors. Prompt recognition and a collaborative approach between gastroenterologists and ophthalmologists are crucial for improving patient outcomes.

Objective. This research delves into decompensated heart failure (DHF), aiming to comprehensively evaluate and compare biomarkers within a tertiary care center. Recognizing DHF's clinical challenges and high morbidity and mortality rates, the study seeks to enhance understanding and shed light on underlying mechanisms, particularly the role of biomarkers. Methodology. Utilizing a retrospective cohort design, the study spans electronic health records from 2010 to 2022. Ethical considerations, including IRB approval and informed consent, are paramount. Biomarkers such as cardiac troponins, B-type natriuretic peptide (BNP), and C-reactive protein (CRP) undergo rigorous assessment via advanced laboratory techniques. Statistical analyses, encompassing t-tests and ANOVA, provide a robust foundation for discerning patterns and correlations. This study includes 200 patients diagnosed with DHF (experimental group) and 200 control patients without DHF (control group). Results. Baseline characteristics highlight subtle differences between DHF patients (experimental group) and controls. Biomarker analysis reveals statistically significant elevations in cardiac troponins, BNP, and CRP in DHF cases compared to controls. The mean levels in survivors and non-survivors underscore the potential prognostic value of these biomarkers. ANOVA results suggest no significant differences in age, gender distribution, and BMI between the groups, reinforcing the robustness of the findings. Conclusion. This study significantly contributes to DHF management insights, emphasizing the diagnostic and prognostic potential of biomarkers. The observed disparities in biomarker levels, coupled with consistent baseline characteristics, provide valuable insights for clinical considerations and future research in DHF management. The nuanced interpretation of results not only expands knowledge of DHF but also offers actionable insights for clinicians dealing with this complex condition.

Исследуется явление реверсивного характера деформаций в предразрушаюей области образца горной породы при одноосном сжатии на основе модельных представлений теории самоуравновешенных напряжений с учетом экспериментально наблюдаемой деформационной картины на поверхности образца. Экспериментальные данные получены с помощью акустико-деформационного метода. Актуальность данного исследования связана именно с развитием неклассических модельных представлений механики деформируемого твердого тела, эволюции напряженно-деформируемого состояния в массивах и образцах горных пород при разного рода силовых воздействиях. Разработан метод определения полной картины напряженно-деформированного состояния во всем объеме образца на протяжении всей истории нагружения.

The phenomenon of reversible deformat-on in the pre-destructive region of a rock specimen under uniaxial compression is investigated on the basis of model representati-ons of the theory of self-equilibrated stresses, taking into account the experimentally observed deformation pattern on the specimen surface. The experimental data were obtained using the acoustic-deformation method. The relevance of this study is related to the development of non-classical model representat-ions of mechanics of deformable solid bodies, the evolution of stress-strain state in arrays and rock samples under different kinds of force actions. A method for determining the complete stress-strain state in the entire volume of the specimen throughout the entire loading history has been developed.

Проблема получения непрерывных полей пластических деформаций при решении задач плоского напряженного состояния, в отличие от плоского деформированного состояния, характерна для всех моделей идеального упругопластического тела, включающих кусочно-линейные функции пластичности. Однако в ряде западных научных статей считается, что только модель идеального упругопластического тела с условием пластичности Треска неправильно прогнозирует неупругие деформации. В настоящей работе определяются границы изменения внешних параметров нагрузки, для которых диск будет находиться в упругом состоянии. Напряжения связаны с упругими деформациями законом Гука. В зависимости от значений параметров нагрузки пластическая область может зарождаться на внутренней границе диска, или на внешней границе диска, или на обеих границах одновременно. Рассматриваются разные условия пластичности. Показан вид годографа вектора напряжений.

Problem obtaining continuous fields of plastic deformations when solving problems of a plane stress state, in contrast to a plane deformed state, is characteristic of all models of an ideal elastoplastic body that include piecewise linear plasticity functions. However, only the model of an ideal elastoplastic body with the Tresca plasticity condition in a number of Western scientific articles is considered to incorrectly predict inelastic deformations. In this work, the boundaries of changes in external load parameters are determined for which the disk will be in an elastic state. Stresses are related to elastic deformations by Hooke’s law. Depending on the values of the load parameters, a plastic region can nucleate on the inner boundary of the disk, either on the outer border of the disk, or on both borders simultaneously. Various plasticity conditions are considered. The view of the stress hodograph vector is shown.

Este Texto para Discussão apresenta e analisa os dados sobre a população em situação de rua (PSR) disponíveis no Cadastro Único para Programas Sociais do Governo Federal (CadÚnico). O objetivo é apresentar alguns subsídios ao aprimoramento das políticas públicas voltadas a esse público, oferecendo um diagnóstico de âmbito nacional da situação atual. O texto também apresenta um método de organização e análise de dados sobre a PSR no CadÚnico. Uma série de fatores fizeram com que cada vez mais cidadãos fossem para as ruas na última década. Com a chegada da pandemia de covid-19, a situação dessas pessoas se agravou. Provocado a se pronunciar, o Supremo Tribunal Federal (STF) emitiu uma medida cautelar em 25 de julho de 2023. Ela destaca a necessidade, pelo Executivo federal, da elaboração de um plano de ação, e, como parte desse plano, de um diagnóstico da situação atual. Sobre os motivos que levam pessoas à situação de rua, sobressaem-se os de ordem econômica, os conflitos familiares e as razões de saúde mental e física. Os fatores econômicos estão associados a um tempo menor de permanência nas ruas; nos demais casos, verifica-se o oposto. Os temas migrações, locais de repouso, vínculos familiares e de participação comunitária, raça ou cor, sexo, idade e deficiências são analisados. Destaca-se que as mulheres são apenas 11,6% da PSR adulta, mas representam 35% das responsáveis familiares entre a parcela da PSR que vive com as famílias nas ruas. O texto também aborda o acesso à documentação, à saúde, aos serviços de assistência social e ao Programa Bolsa Família (PBF), bem como a escolaridade e a dimensão do trabalho e da geração de renda. Mesmo entre os possuidores de algum tipo de registro civil, 24% não possuem certidão de nascimento. Entre os adultos, 24% não têm carteira de trabalho e 29% não têm título de eleitor. Apenas 58% de crianças e adolescentes de 7 a 15 anos, em situação de rua, frequentam a escola. Da população adulta nesse contexto, 69% realizam alguma atividade para conseguir dinheiro, mas apenas uma ínfima minoria de 1% tinha um emprego com carteira assinada.

The existence of two distinct and apparently unrelated populations of dusty stellar objects in the Nuclear Stellar Cluster of the Milky Way, namely IRS 13 and the S-cluster, are potentially prone to a general process describing the star formation history in the Galactic center (GC). The former cluster is thought to be entangled in the clockwise and counterclockwise disks, a large-scale stellar distribution revealed by the analysis of stars at different distances from Sgr A*, the supermassive black hole in the GC. Recently, this large-scale distribution was reported to exhibit a multidisk structure with at least four components. Motivated by this finding, we revisit the anisotropic IRS 13 cluster and find strong evidence for a disk-like structure. An examination of about 50 individual stellar orbits reveals a new structure that does not follow any trend known in the literature. Furthermore, we investigate the possibility of an inspiral cluster undergoing star formation processes, as proposed by several authors. Using a simplified N-body simulation to reproduce our observational results, we conclude that, under certain conditions, a massive cluster can migrate from the Circum Nuclear Disk toward the inner parsec. Based on this classification, we revisit the large-scale NACO Very Large Telescope (VLT) observations of IRS 13 and find evidence for a separation of the cluster into a gravitationally stable core remnant and a dissipating part. With the velocity-resolved H30α line and the broadband spectral energy distribution of IRS 13 E3, we provide tentative support for the existence of an intermediate-mass black hole of ∼3 × 104

Partially ionized plasmas consist of charged and neutral particles whose mutual collisions modify magnetic reconnection compared with the fully ionized case. The collisions alter the rate and locations of the magnetic dissipation heating and the distribution of energies among the particles accelerated into the nonthermal tail. We examine the collisional regimes for the onset of fast reconnection in two environments: the partially ionized layers of the solar atmosphere, and the protoplanetary disks that are the birthplaces for planets around young stars. In both these environments, magnetic nulls readily develop into resistive current sheets in the regime where the charged and neutral particles are fully coupled by collisions, but the current sheets quickly break down under the ideal tearing instability. The current sheets collapse repeatedly, forming magnetic islands at successively smaller scales, until they enter a collisionally decoupled regime where the magnetic energy is rapidly turned into heat and charged-particle kinetic energy. Small-scale, decoupled fast reconnection in the solar atmosphere may lead to preferential heating and energization of ions and electrons that escape into the corona. In protoplanetary disks such reconnection causes localized heating in the atmospheric layers that produce much of the infrared atomic and molecular line emission observed with the Spitzer and James Webb Space Telescopes.

The phenomenon of pulsar nulling, where pulsars temporarily and stochastically cease their radio emission, is thought to be indicative of a “dying” pulsar, where radio emission ceases entirely. Here we report the discovery of a long-period pulsar, PSR J0452−3418, from the ongoing Southern-sky MWA Rapid Two-meter pulsar survey. The pulsar has a rotation period of ∼1.67 s and a dispersion measure of 19.8 pc cm−3, and it exhibits both quasiperiodic nulling and subpulse drifting. Periodic nulling is uncommon, reported in only <1% of the pulsar population, with even a smaller fraction showing periodic nulling and subpulse drifting. We describe the discovery and follow-up of the pulsar, including a positional determination using high-resolution imaging with the upgraded Giant Metrewave Radio Telescope (uGMRT), initial timing analysis using the combination of Murchison Widefield Array (MWA) and uGMRT data, and detailed characterization of the nulling and drifting properties in the MWA’s frequency band (140–170 MHz). Our analysis suggests a nulling fraction of 34% ± 6% and a nulling periodicity of

Photometric Properties within the Reiner Gamma Swirl: Constraining Formation Mechanisms
Authors: Domingue Deborah , Weirich John , Chuang Frank , Courville Samuel , Clark Roger , Sickafoose Amanda , Palmer Eric , Gaskell Robert
Published: July 2024

The area in the Reiner Gamma swirl studied by Weirich et al. for topographic correlations also displays correlations with the Hapke-model-derived single-scattering albedo, surface roughness, and particle scattering properties with swirl unit. The correlations with single-scattering albedo associate compositional variations in plagioclase and FeO content with swirl unit. The correlations with photometric surface roughness show a rougher surface on-swirl, implying a potentially more porous surface on-swirl compared to off-swirl. This suggests the variations in single-scattering albedo are dominated by the compositional differences and not structural differences, such as compaction. Grain-size differences could still contribute to the albedo variations. Differences in particle scattering properties between on-swirl and off-swirl are counter-indicative of the trend expected from variations in space weathering, unless there is a process to initiate either size sorting or compositional differences. The photometric properties point to a complex interaction of multiple processes to form the swirl units, not a singular dominant process. Variations in weathering, dust mobilization and entrapment, and impact modification may all play a key role.
Preliminary evaluation of the green microalga Dunaliella salina as a potential feedstock for biodiesel: effect of molasses on growth and lipid profile

This research aims to evaluate the effect of molasses as a source of organic carbon on the growth and lipid profile of Dunaliella salina cultivated under different light regimes to determine its strategy and potential use to produce biodiesel. Two sources of nutrients (F/2 medium, F/2; molasses, M) and two light conditions (12 h light: 12 h darkness, 12L:12D) conformed four treatments (F/2 12L:12D, F/2 D, M 12L:12D, and MD) that were investigated with three replicates each. The concentration of microalgae produced by the groups under light conditions was more than double that of those grown in darkness. The highest biomass produced (46.91 ± 6.47 g L-1) was obtained in the F/2 medium with 12L:12D treatment, while the lowest (18.99 ± 0.78 g L-1) was in the M 12L:12D group. Regardless of the culture conditions, the lipids were mainly composed of the C16:0 and C18 fatty acids. The use of molasses as a culture medium produced the highest amount of C18:1, regardless of the light regime. Molasses promoted the highest production of fatty acids methyl esters. Depending on the culture medium, D. salina cells showed different percentages of saturated (SFA), monounsaturated (MFA), and polyunsaturated (PUFA) fatty acids. The highest amount of saturated fatty acids was obtained in F/2 12L:12D. The highest amount of polyunsaturated fatty acids was presented in the mixotrophic culture (molasses and light). The cultures grown with molasses were rich in monounsaturated fatty acids. An inexpensive industrial by-product, Cane molasses could be a low-cost feedstock for biodiesel in cultivating D. salina.
Job insecurity and moral disengagement in frontline employees: A moderated mediation effect of perceived organizational support and occupational regret
Authors: Gautam Prakash Kumar , Gautam Dhruba Kumar
Published: July 2024

Purpose: The study's purpose is to analyze the effect of job insecurity on the moral disengagement of frontline employees during the COVID-19 pandemic. It also analyzes the moderated mediation model incorporating occupational regret and perceived organizational support.Design/Methodology: This study used analytical research design to analyze the moderated mediation effect. Frontline employees working at least three days a week were selected as the respondents and data were collected through the structured questionnaire survey. Hayes's approach was used to examine the moderated mediation model adopting a 95% level of confidence.Findings: The result revealed that job insecurity is a significant predictor of moral disengagement during the COVID-19 pandemic. In addition, occupational regret mediated the predicting ability of job insecurity and moderated by organizational support. This study highlights the essence of organizational support to reduce moral disengagement as a consequence of job insecurity and occupational regret.Implications: This study contributes to the social cognitive theory. In addition, it recommends that management practitioners ensure organizational support to minimize employees’ disengagement. Further, it supports minimizing employees’ feelings of job insecurity and occupational regret by maintaining a supportive organizational environment. Originality/Value: This study adds value by examining the mediation effect of occupational regret in the relationship between predicting variable job insecurity and outcome variable moral disengagement. It also  examines the moderation effect of perceived organizational support in the mediation model. Thus, this study suggests an integrated model. Further, this study provides recommendations for future research that gauge the level of understanding to manage employees’ moral disengagement during the crisis because of intense job insecurity feelings and occupational regret.
Examining Factors Associated With Intention to Seek Professional Mental Health Support Among First-Generation Iranian Americans
Authors: Mohammadifirouzeh Mona , Oh Kyeung Mi , Basnyat Iccha , Gimm Gilbert
Published: July 2024

Purpose

Research suggests immigrants are at a greater risk of mental health disorders compared to native-born populations. Thus, the current study investigated factors associated with professional mental help-seeking intention among American immigrants.

Method

A cross-sectional study was conducted with 207 first-generation Iranian Americans, and data were collected using survey questionnaires.

Results

Younger Iranians living in western states in the United States and those with positive attitudes toward professional mental health services had greater intention to seek these services. Unexpectedly, those with better mental health literacy (MHL) held more mental health stigma (MHS).

Conclusion

Findings elucidated valuable insights into the complex dynamics among sociodemographic factors, acculturation, MHL, MHS, attitudes, and intentions toward professional mental health help-seeking. We also highlighted the intricate relationship between MHL and MHS, suggesting that strategies to improve MHL may not necessarily mitigate MHS within this community. Therefore, integrating anti-stigma, contact-based approaches to MHL programs could effectively reduce stigma while facilitating mental health help-seeking. [

Parental Substance Use Disorder and the Rise in Children Being Raised by Grandparents: Focusing on Children's Needs and Improving Outcomes
Authors: Mechling Brandy , Ahern Nancy , Palumbo Ruthanne
Published: July 2024

The occurrence of children being raised solely by their grandparents has steadily risen in the past decade prompted by parental substance use disorder (SUD) and associated incarceration and death. These families, especially children, are a vulnerable population with unique needs. Nurses should be cognizant of the needs, risk factors, and protective factors often associated with this population. Meanwhile, the literature to date mostly focuses on grandparents. School and pediatric nurses, specifically, are in an advantageous position to help support these families and help foster better child outcomes. The purpose of the current article is to explore the experiences, needs, and resources for supporting children being raised by grandparents due to parental SUD. Best practices for health care professionals, especially nurses, are discussed as well as future directions for research with this vulnerable population. [

On a singular parabolic $ p $-Laplacian equation with logarithmic nonlinearity
Authors: Wu Xiulan , Zhao Yaxin , Yang Xiaoxin
Published: July 2024

In this paper, we considered a singular parabolic $ p $-Laplacian equation with logarithmic nonlinearity in a bounded domain with homogeneous Dirichlet boundary conditions. We established the local solvability by the technique of cut-off combining with the method of Faedo-Galerkin approximation. Based on the potential well method and Hardy-Sobolev inequality, the global existence of solutions was derived. In addition, we obtained the results of the decay. The blow-up phenomenon of solutions with different indicator ranges was also given. Moreover, we discussed the blow-up of solutions with arbitrary initial energy and the conditions of extinction.
What's Wrong with Bullshit
Authors: Cova Florian
Published: July 2024

Past philosophical analyses of bullshit have generally presented bullshit as a formidable threat to truth. However, most of these analyses also reduce bullshit to a mere symptom of a greater evil (e.g. indifference towards truth). In this paper, I introduce a new account of bullshit which, I argue, is more suited to understand the threat posed by bullshit. I begin by introducing a few examples of “truth-tracking bullshit”, before arguing that these examples cannot be accommodated by past, process-based accounts of bullshit. I then introduce my new, output-based account of bullshit, according to which a claim is bullshit when it is presented as or appears as interesting at first sight but is revealed not to be that interesting under closer scrutiny. I present several arguments in favor of this account, then argue that it is more promising than past accounts when it comes to explaining how bullshit spreads and why it is a serious threat to truth.
