IMF and Global Public Goods: seeking a new role in the global economy
Authors: Kopiński Dominik , Nowicki Michał , Wróblewski Marek
Published: April 2024

Current global economic challenges have stimulated public demand for coordinated activities at a transnational level (as evidenced by the impact of the COVID-19 pandemic crisis). In this context, academic discourse and the forums of various multilateral organizations have invoked the concept of global public goods (GPGs). This paper explores the practical realization of the GPGs concept within the global structures of the International Monetary Fund (IMF), assessing the extent to which the wealth of services provided by the Fund may actually be considered GPGs. Approaching the subject from a theoretical perspective, the paper draws on analytical evaluations of relevant documents and IMF data sources, as well as empirical findings derived from semi-structured in-depth interviews (IDI) with representatives of international organizations (including the IMF) in Washington, DC. The findings suggest that the IMF provides a diverse array of products supportive of international financial stability (particularly ‘best-shot public goods’), and may therefore be regarded as exemplifying the GPGs concept. During times of relative global economic stability, IMF expenditure shifts toward technical support and monitoring, placing the organization in a role more akin to a provider of pure public goods. However, despite the IMF enjoying a number of competitive advantages (and resources) that would seem to preordain a role as a major GPGs provider, the GPGs concept is only marginally evoked in the organization’s publications and activities. Moreover, certain elements of the IMF’s model of operation drastically reduce the organization’s current operating capability as a GPGs provider.
Менеджмент «лица» в практиках современной деловой культуры Китая (в печати)
Authors: Скальная О.А. , Лукьянова Н.А.
Published: April 2024

Интерес к современной китайской культуре связан с процессами активизации экономических и культурных связей между Россией и Китаем. Одним из аспектов, обусловивших интерес к китайской культуре, является желание современных бизнесменов понять специфику менеджмента в Китае для установления стабильных связей. Изучение практик взаимодействия в китайском бизнесе позволяет понять истоки традиционных практик деловой культуры Китая (конфуцианский динамизм), а также описать цифровые форматы делового взаимодействия с китайской спецификой. Актуальность предлагаемого исследования заключается в том, что культурный концепт «лица» имеет центральное место в китайской системе ценностей и является ключом к пониманию национального характера китайцев. Такие культурные характеристики китайского общества как коллективизм, ориентация на долгосрочность, гармония в межличностных отношениях, высококонтекстность и невербальность требуют изучения в контексте практик современного менеджмента. К одной из таких практик относится менеджмент «лица». Различные коммуникативные стратегии и культурные практики в современном китайском обществе, в том числе и в бизнесе, базируются на смысловых традициях концепции «лица», органично записанных в коллективный интеллект китайского народа. В цифровом мире межкультурные деловые коммуникации переходят в новые форматы, создавая иную субкультуру, в которой менеджмент «лица» также видоизменяется. Данные онлайн-практики «работы над лицом» становятся неотъемлемой частью современной китайской деловой культуры и заслуживают особого внимания. Цель данной статьи – на основе анализа традиционных практик в китайской деловой культуре раскрыть сущность менеджмента «лица», рассмотреть влияние цифровых трансформаций на деловые практики «работы с лицом». Результаты. Описаны универсальные и специфичные китайские аспекты феномена «лица» в менеджменте. Показано, что управление «лицом» – сложный коммуникативный механизм, ему присущи ситуативность и динамичность. Выявлено, что концепт «лица» имеет в цифровой культуре важное значение в глокальном контексте делового взаимодействия. В процессах цифровизации менеджмент «лица» присутствует в новых форматах, однако традиционные традиционные культурные практики, связанные с «лицом», по-прежнему оказывают существенное влияние на деловое общение. Сделан вывод, что сложность овладения навыками управления «лицом» в процессах кросс-культурных коммуникаций вызвана наличием различных неписаных социальных ритуалов, связанных с «лицом», которые иностранцу, вне контекста китайской социальной среды, могут быть непонятны.

Introduction

In recent years, premature “deaths of despair” (ie, due to alcohol, drug use, and suicide) among middle-aged White Americans have received increased attention in the popular press, yet there has been less discussion on what explains premature deaths among young African Americans. In this study, we examined factors related to deaths of despair (alcohol use, drug use, smoking) and contextual factors (perceived discrimination, socioeconomic status, neighborhood conditions) as predictors of premature deaths before the age of 65 years among African Americans.

Methods

The Jackson Heart Study (JHS) is a longitudinal cohort study of African Americans in the Jackson, Mississippi, metropolitan statistical area. We included participants younger than 65 years at baseline (n=4000). Participant enrollment began in 2000 and data for these analyses were collected through 2019. To examine predictors of mortality, we calculated multivariable adjusted hazard ratios (HRs; 95% CI), using Cox proportional hazard models adjusted for age, sex, ideal cardiovascular health metrics, drug use, alcohol intake, functional status, cancer, chronic kidney disease, asthma, waist circumference, depression, income, education, health insurance status, perceived neighborhood safety, and exposure to lifetime discrimination.

Results

There were 230 deaths in our cohort, which spanned from 2001-2019. After adjusting for all covariates, males (HR, 1.50; 95% CI, 1.11-2.03), participants who used drugs (HR, 1.53; 95% CI, 1.13-2.08), had a heavy alcohol drinking episode (HR, 1.71; 95% CI, 1.22-2.41), reported 0-1 ideal cardiovascular health metrics (HR, 1.78; 95% CI, 1.06-3.02), had cancer (HR, 2.38; 95% CI, 1.41-4.01), had poor functional status (HR, 1.68; 95% CI, 1.19-2.37), or with annual family income less than $25,000 (HR, 1.63; 95% CI, 1.02-2.62) were more likely to die before 65 years of age.

Conclusions

In our large cohort of African American men and women, clinical predictors of premature death included poor cardiovascular health and cancer, and social predictors included low income, drug use, heavy alcohol use, and being a current smoker. Clinical and social interventions are warranted to prevent premature mortality in African Americans.

Bridging the Gap : Bilinguale Bilderbücher als interkulturelle Brückenbauer in einer multiethnischen Gesellschaft
Authors: Wieland Jasmin
Published: April 2024

Multiethnische Gesellschaften sind in Zeiten von Globalisierung und weltweiter Migration aufgrund von Kriegen und Krisen die Normalität. Der Kontakt unterschiedlicher Kulturen und Sprachen stellt die Gesellschaften dabei vor Herausforderungen, die zugleich Chancen sind. Der interkulturelle Dialog ist für das Gelingen eines harmonischen Zusammenlebens unterschiedlicher Kulturen zentral. Werte wie Offenheit und Toleranz werden dabei groß geschrieben. Bilinguale Bilderbücher stellen ein Medium dar, Interkulturalität zu fördern und so Brücken zwischen Kulturen zu bauen. Diese Studie untersucht in einem interdisziplinären Ansatz aus Literatur- und Kulturwissenschaft sowie Pädagogik, inwiefern bilinguale Bilderbücher zwei oder mehrere Kulturen verbinden und so einen interkulturellen Austausch anregen können. Schwerpunkmäßig werden die Kategorien ‚Mehrsprachigkeit‘, ‚visuelle Codes‘ sowie ‚Thematiken‘ beleuchtet. Die multiethnische Gesellschaft Deutschlands und die in ihr gesprochenen Sprachen dienen als Ausgangspunkt für die Untersuchung, ebenso die Verlagsprogramme der mehrsprachigen Kinderbuchverlage des deutschsprachigen Buchmarkts. Ein Blick in die pädagogische Praxis wird in der Analyse einer qualitative Umfrage geworfen, bei der mehrsprachig erziehende Eltern sowie Pädagog:innen der frühkindlichen Erziehung und der Primarstufe zum Einsatz bilingualer Bilderbücher befragt wurden.
Ritornelo e TikTok
Authors: Takara Samilo
Published: April 2024

Este texto problematiza o TikTok como rede produzida por meio do uso de artefatos midiáticos como os smartphones e a possibilidade de pensar o uso do conceito de ritornelo, tal como empregam Gilles Deleuze e Félix Guattari (2014), no texto Acerca do Ritornelo. Diante da compreensão da sonoridade como um dos efeitos que territorializam espaços na vida e, em diálogo com a contribuição das pedagogias culturais investigadas por autorias dos Estudos Culturais, este texto tem por objetivo problematizar as possibilidades pedagógicas do TikTok. Este é um estudo qualitativo, exploratório e bibliográfico e investe analíticas na proposta de problematizar os efeitos pedagógicos da mídia contemporânea na educação das subjetividades. Desse modo, compreende-se que os áudios acionados em diferentes tipos de produções nessa rede, como a dublagem, o dueto e a costura, possibilitam a criação de ritornelos que localizam aspectos pedagógicos acerca dos modos de ser, estar e agir na contemporaneidade.
Biopolítica e normalização dos corpos em XXY
Authors: Zoboli Fabio , Galak Eduardo , Gomes Ivan Marcelo
Published: April 2024

A trama do filme XXY (2007) da diretora argentina Lucía Puenzo gira em torno de uma reflexão que questiona como a ciência moderna arquiteta a tríade “corpo-sexo-gênero” na sua ânsia de categorizar e ordenar os corpos via dispositivo dos saberes da biologia que os classifica de modo binário. O texto objetiva pensar o corpo intersexo de Alex em XXY em termos políticos a partir de duas questões: “O que se pode fazer com um corpo?” e “O que pode o corpo?”. Deste modo o corpo de Alex será interpelado pelos dispositivos biopolíticos da normalidade e pela potência deste corpo que sofre por assumir sua condição de existência. Conclui-se que a trama fílmica de XXY expõe o híbrido das condições sociais de existência e experiência, a impureza dos nossos corpos, imperfeitos, intercambiáveis e com intervenções.
Educação integral
Authors: Maciel Antônio Carlos , Jacomeli Mara Regina Martins , Silva Cintia Adélia da
Published: April 2024

Este artigo examina conceitos utilizados na literatura sobre educação integral com o objetivo de explicitar a relação entre princípios epistemológicos e finalidades pedagógica e ideológica das políticas educacionais, que fundamentam as experiências pedagógicas realizadas no Brasil. Para tanto, utiliza-se a técnica de análise histórico-crítica (Maciel; Braga, 2008; Saviani, 2003), metodologicamente fundamentada no materialismo histórico-dialético (Marx, 1983a; Netto, 2011), pela qual se torna possível apurar lacunas, omissões, equívocos e imprecisões conceituais (denominados metaforicamente, aqui, de ruídos analógicos), entre princípios epistemológicos e finalidades político-ideológicas. Por este caminho, descobre-se que os ruídos analógicos consistem em desvincular princípios epistemológicos das finalidades político-ideológicas das pedagogias, técnica por meio da qual se dilui a história no presente, suprime-se a gênese e as contradições do processo. A partir de 2007, as experiências pedagógicas em educação integral no Brasil deixam de ser raras e pontuais, porém, quanto mais se fala, menos se faz educação integral na escola pública.
Galactic Symmetry
Authors: Oldani Richard
Published: April 2024

Differences between the quantum mechanical and relativistic concepts of time observed in GPS satellites are accounted for by applying the equivalence principle to the transitioning electron of an atomic clock. It allows a differential equation of motion to be derived for the electron in the Minkowski space between electron shells. Using Hamilton’s principle we transform the differential equation relativistically into an integral equation of motion, the time integral of a Lagrangian. This newly derived equation accounts for the abstract mathematics of the more familiar non-relativistic model by means of a physical interpretation. Abstract rotations in Hilbert space are replaced by the rotations of real particle field geometries in Minkowski space. Because the properties of energy are universal the same equations are then used to describe the field geometry of galaxies despite vast differences in lifetime. They reveal a symmetry between the electromagnetic fields of atoms and the gravitational fields of galaxies due to similarities in the exchange of energy by radial and transverse fields. Our analysis reveals that the conjugate variables energy and time permit differences between atomic and galactic structure to be compared in a more intuitive way than by means of the differential equations of motion which use the conjugate variables position and momentum.
Description of Mesoscale Static and Fatigue Analysis of 2D Woven Roving Plates with Convex Holes and Subjected to Axial Tension
Authors: Muc Aleksander
Published: April 2024

Abstract—The static and fatigue analysis of plates with holes, made of 2D woven roving composites, is conducted. The parametrization of convex holes is proposed. Experimental results of specimens without holes and with different shapes of notches are discussed. The fatigue behaviour is considered with the use of the low cycle fatigue method. The analysis is supplemented by the numerical finite element modeling.
The present work is an extension of the results discussed in the literature. The finite element
modeling of plates with holes is presented in details in Ref [1-3] including also the problems of the accuracy. The experimental results and the form of specimens are shown in Ref [4].
Two parametrical description of static and fatigue behaviour of plates with holes characterizes the goal and the novelty of the paper. The fuzzy approach is employed to reduce the number of experimental data [5].
On the Natural Intelligence and Consciousness of the Immune System and Its Relationship with the Brain
Authors: Ruggiero Marco , Hiratsuka Akira
Published: April 2024

In this article, we consider the relationship between the brain and the immune system in the context of the Orch OR (Orchestrated Objective Reduction) theory of consciousness. Orch OR is a theory that postulates that consciousness arises from quantum computations occurring inside microtubules. The immune system is capable of acquiring, learning, and remembering information, thus showing all the attributes of natural intelligence. We argue that the immune system also has the attribute of consciousness and can gain access to an amount of information greater than what is accessible to the brain since it is not constrained by brain's reducing valve that is responsible for cognitive bottlenecks. We also describe the role of meditation and religious chanting in affecting the brain and immune system. We speculate that some effects of religious chanting on the immune system may not be mediated by the brain. Finally, we examine the role of the immune system in connecting with the consciousness embedded in the universe.
Assembly Theory of Binary Messages (How to Assemble a Black Hole and Use it to Assemble New Binary Information?)
Authors: Łukaszyk Szymon , Bieniawski Wawrzyniec
Published: April 2024

Using assembly theory, we investigate the assembly pathways of binary strings of length N formed by joining the individual bits present in the assembly pool and the strings that entered the pool as a result of previous joining operations. We show that the string assembly index is bounded from below by the shortest addition chain for N, and we conjecture about the form of the upper bound. We define the degree of causation for the minimum assembly index and show that it features patterns that can be used to determine the shortest addition chain for certain N. We show that a string with the smallest assembly index can be assembled by an elegant trivial program of length equal to this index if the length of the string is expressible as a product of Fibonacci numbers. We conjecture that there is no binary program that has a length shorter than the length of the string having the largest assembly index that could assemble this string. We conjecture that a black hole surface is defined by a balanced distinct string that satisfies the upper bound of a distinct string assembly index. The results confirm that four Planck areas provide a minimum information capacity that provides a minimum thermodynamic (Bekenstein-Hawking) entropy. Knowing that the problem of determining the assembly index is at least NP-complete, we conjecture that the problem of determining the assembly index of a given binary string is NP-complete, while the problem of creating the string so that it would have a predetermined maximum assembly index is NP-hard. Therefore, once the new information is assembled by a dissipative structure or by a human, increasing the information entropy according to the second law of infodynamics, it is subject to the second law of thermodynamics, and nature seeks to optimize its assembly pathway.
Introducing Novel Geometric Insights and Three-Dimensional Depictions of the Pythagorean Theorem for Any Triangles
Authors: Dos Santos Bernardes Marco Aurélio
Published: April 2024

The paper primarily demonstrates that the three internal triangles formed by connecting any point on a midsegment with the vertices of a generic triangle satisfy the geometric Proof of the Pythagorean theorem in Euclidean geometry. Moreover, this study elucidates the Pythagorean relationships inherent within three-dimensional geometric constructs resulting from the arrangement of three-dimensional spatial triangles. This geometric relationship, akin to a generalized extension of the Pythagorean theorem, unveils a unique spatial region characterized by this harmonious area interrelation among triangles.
Conceptualizing an Interferometer with Multiple Beams Splitting and Multiple Interference
Authors: Inioluwa Precious Adegbite
Published: April 2024

This article proposes an interferometer which should in principle split further an initially split beam to yield new sets of beams, effectively multiplying the number of beams that can be subjected to detectable interference. It can be considered a modification to the Michelson interferometer that introduces additional arrays of beam splitters, mirrors and detectors. It is expected of the interferometer to provide us with a set or sets of data holding details of phase changes in multiple interference patterns detectable by multiple detectors, enabling comparative analysis of data for multiple interference patterns recorded from a single measurement or activity. The number of multiplied beams possible is not limited, as it only depends on the specific amount of beam splitters required for certain experiments and practicals. The interference of multiple beams may improve sensitivity and detection for instrumentation purposes. The use of multiplied beam interferometry may also extend to quantum computation, particularly in linear optical quantum computation scheme as it enable production of multiple coherent beams which may exhibit properties of entanglement, making it suitable for developing optical multi-qubit systems.
A Simple Method for Identifying the Natural Frequency of a Micro Satellite with a Primary Structure made of Aluminum Alloy
Authors: Okuyama Keiichi , Yoshikawa Keigo , Oue Chihiro
Published: April 2024

Micro satellites must survive severe mechanical conditions during their launch phase. Therefore, structural design requirements are imposed on the micro satellites. These requirements are the strength requirement and the stiffness requirement. Usually, the structural design of a micro satellite is performed using the internal stress analysis and the natural frequency analysis, which are based on a Finite Element Method (FEM). The validity of this structural design is evaluated through vibration tests. In an early stage of development, which has a FEM model of a satellite in the process of creation, presumption of the natural frequency of a satellite may be difficult. In this study, a simple method for determining the longitudinal and lateral minimum natural frequencies of the micro satellites during the ascent phase was clarified. The structure of the micro satellites used in this research is made of aluminum alloy, and they have a monocoque structure. The Young's modulus and moment of inertia of area used to calculate the minimum natural frequencies were determined using the area ratio of the monocoque structure to the entire satellite. When this method is used, the estimated minimum natural frequencies of the longitudinal direction and the lateral direction are in agreement with the measured values acquired by the vibration tests. In order to shorten the process of micro satellites development, this paper describes a practical estimation method of the minimum natural frequency for micro satellites.
Fruit Harvest Helper: A Cross-Platform Mobile Application For Fruit Yield Estimation
Authors: Duncan Brandon , Bulanon Duke , Bulanon Joseph Ichiro Jimeno , Nelson Josh
Published: April 2024

The Fruit Harvest Helper, a mobile application developed by Northwest Nazarene University’s (NNU) Robotics Vision Lab, aims to assist farmers in estimating fruit yield for apple orchards. Currently, farmers manually estimate the fruit yield for an orchard, which is a laborious task. Fruit Harvest Helper seeks to simplify their process. While prior research efforts at NNU concentrated on developing an iOS app for blossom detection, this current research aims to adapt that smart farming application for apple detection across multiple platforms, iOS and Android. The old and new applications were designed with an intuitive user interface that is easy for farmers to use, allowing for quick image selection and processing. Unlike before, the adapted app utilizes a color ratio-based image segmentation algorithm implemented in OpenCV C++ to detect apples in apple tree images selected for processing. The results of testing the algorithm with a dataset of images indicate an 8.52% Mean Absolute Percentage Error (MAPE) and a Pearson correlation coefficient of 0.6 between detected and actual apples on the trees. These findings were obtained by evaluating the images from both the east and west sides of the trees, which was the best method to reduce the error of this algorithm. Although the Fruit Harvest Helper shows promise, there are many opportunities for improvement. These opportunities include exploring alternative machine-learning approaches for apple detection, conducting real-world testing without any human assistance, and expanding the app to detect various types of fruit. The Fruit Harvest Helper mobile application is among the many mobile applications contributing to precision agriculture, nearing readiness for farmers to use in yield monitoring and farm management.

Analysis of Missingness Scenarios for Observational Health Data
Authors: Zamanian Alireza , von Kleist Henrik , Ciora Octavia Andreea , Piperno Marta , Lancho Gino , Ahmidi Narges
Published: April 2024

Despite the extensive literature on missing data theory and cautionary articles emphasizing the importance of realistic analysis for healthcare data, a critical gap persists in incorporating domain knowledge into missing data problem formulation, assumption specification, and method development. In this paper, we highlight the gap particularly for observational data from healthcare facilities. We address this gap by identifying ten fundamental missingness scenarios arising during data measurement, recording, and pre-processing in observational health data, influenced by physicians, patients, healthcare facilities, and data scientists. We analyze the effect of scenarios on estimand formulation, missing data identification, estimation, and sensitivity analysis. To emphasize how domain-informed analysis can improve method reliability, we conduct simulation studies under the influence of various missingness scenarios. We compare the results of three common methods in medical data analysis (complete-case analysis, Missforest imputation, and inverse probability weighting estimation) for two estimands (variable mean estimation and classification accuracy). We advocate for our analysis approach as a reference for the analysis of observational health data. Furthermore, we posit that the proposed analysis framework is applicable to other medical domains, including medical wearable data analysis.
Landauer Bound in the Context of Minimal Physical Principles: Meaning, Experimental Verification, Controversies and Perspectives
Authors: Bormashenko Edward
Published: April 2024

The physical roots, interpretation, controversies and precise meaning of the Landauer Principle are surveyed. Landauer's principle is a physical principle pertaining to the lower theoretical limit of energy consumption of computation. It states that an irreversible change in information stored in a computer, such as merging two computational paths, dissipates a minimum amount of heat kBTln2 per a bit of information to its surrounding. The Landauer Principle is discussed in the context of fundamental physical limiting principles, such as the Abbe diffraction limit, the Margolus-Levitin limit and the Bekenstein limit. Synthesis of the Landauer bound with the Abbe, Margolus-Levitin limit and Bekenstein limits yields the minimal time of computation, which scales as τmin~hkBT. Decrease in a temperature of a thermal bath will decrease the energy consumption of a single computation, but, in parallel, it will slow the computation. The Landauer principle bridges between John Archibald Wheeler “it from bit” paradigm and thermodynamics. Experimental verifications of the Landauer Principle are surveyed. Interrelation between thermodynamic and logical irreversibility is addressed. Generalization of the Landauer principle to the quantum and non-equilibrium systems is addressed. Landauer Principle represents the powerful heuristic principle bridging the physics, information theory and computer engineering.
Chronic Pediatric Headache as a Manifestation of Shunt Over-Drainage and Slit Ventricle Syndrome in patients harboring a Cerebrospinal Fluid Diversion System: A Systematic Literature Review
Authors: Panagopoulos Dimitrios , Gavra Maro , Boviatsis Efstathios , Korfias Stefanos , Themistocleous Marios
Published: April 2024

The ultimate goal of our review is to draw clinician’s attention, especially of those who are managing pediatric patients with permanent, long-standing, ventriculoperitoneal or, less commonly, ventriculo-atrial shunts. This specific subgroup of patients may eventually suffer from severe, intractable headaches which may negatively impair their quality of daily living. In the absence of any other clinical condition that could be attributed as the cause of the headache, shunt overdrainage should not be overlooked but, on the contrary, should be seriously taken into consideration in the therapeutic armamentarium of such cases, that are difficult to be handled.
CFD Investigation of Hydrodynamic Force and Moment Acting on Stern-Rudder Plane Configurations of a Submarine
Authors: Nguyen Tien Thua , Phan Thanh Long , Mai Thi Loan
Published: April 2024

The paper presents the prediction of hydrodynamic characteristics of different rudder -plane configurations behind a submarine in deep water through the Reynolds-Averaged Navier-Stokes method in Ansys Fluent Solver. The hydrodynamic force and moment acting on the Cross-plane, X-plane, and Y-plane rudder configurations are analyzed for estimating hydrodynamic coefficientsfor predicting the advantages of each configuration to control the ship. The obtained results show that X-force of the X-plane rudder configuration is larger than the force acting on the Cross-plane rudder and Y-plane rudder configurations. However, Y-force, and Z-force of the X-plane rudder configuration are significantly greater than the Y-force of the left configurations. The same tendency can be seen in the moment of the X-plane rudder about the y-axis and z-axis. The roll moment induced by the Y-plane and Cross-plane rudder configurations is significantly larger than the case of the X-plane rudder configuration.
Can Environmental Regulation Enhance Green Total Factor Productivity? —Evidence from 107 Cities in the Yangtze River Economic Belt
Authors: Liu Mengli , Zhu Yan , Zhang Jingjing
Published: April 2024

Promoting green development has become an important way to optimize the ecological and economic structure and promote sustainable development. The Yangtze River Economic Belt is an important economic corridor in China, and it remains to be examined whether the implementation of environmental regulations has enhanced the green total factor productivity (GTFP) of cities. This paper calculates the green total factor productivity of 107 cities within the Yangtze River Economic Belt by using the super-efficient SBM model and the GML index with Chinese city panel data from 2007-2019 and measures the intensity of environmental regulations through textual analysis. The bidirectional fixed-effects model constructed in this paper suggests an inverted U-shaped relationship between environmental regulation and GTFP, which is confirmed by a series of robustness tests. Green technology innovation and advanced industrial structure play a mechanism role in this. In regions with lower levels of green technology and industrial structure, the inverted U-shaped relationship between environmental regulation and green total factor productivity is more significant. In addition, the phenomenon of GTFP rising and then falling because of environmental regulation is more obvious in cities in the middle and upper reaches of the Yangtze River and outside the urban agglomerations. Therefore, when formulating environmental regulation policies, it is necessary to balance the relationship between economic development and environmental protection and harmonize the environment and economic development of the entire Yangtze River Basin.
Factors that Influence Resilience among Undergraduate First-Year Nursing Students: A Cross-Sectional Descriptive Study
Authors: Gause Gopolang , Sehularo Leepile Alfred , Matsipane Molekodi Jacob
Published: April 2024

Transition from basic to higher education is regarded as a ‘juggle of many balls’ because students ought to balance between theoretical and clinical requirements, including social life. As a result, a significant number of undergraduate first-year nursing students succumb to these challenges due to lack of coping mechanisms emanating from poor resilience. As a result, the aim of this study was to determine the factors that influence resilience among undergraduate first-year nursing students at a South African university. A quantitative cross-sectional descriptive research design was followed. Data was collected using an adapted self-administered online questionnaire. Principal component analysis extraction method and Varimax rotation were used to analyse data. A total of 123 participants completed the questionnaire. The eigenvalues showed that the first factor explained 23.9% of the variance, the second factor 11.2%, a third factor 7.5% while the fourth factor explained 5.9% of the variance.

Congenital heart disease (CHD) is a prevalent congenital disorder diagnosed with high frequency, affecting approximately 0.8% to 1.2% of all live births. Research has demonstrated that the use of pulse oximetry and clinical examination as a screening tool for CHD diagnosis has proven extremely valuable. We conducted a retrospective longitudinal study over a 3-year period that involved screening 1188 newborns admitted to the NICU during the first 72 hours of life within this timeframe. 201 newborns were diagnosed with CHD. Almost all (n=198) had a positive screening test during the 72-hour period, while 3 had a negative screening test, but were later diagnosed using echocardiography. The prevalence rate was 16.67%. A confusion matrix was constructed with 198 true positives (TP), 3 false negatives (FN), no false positives (FP), and 987 true negatives (TN). The sensitivity of the screening test was 98.51%, while the specificity 100%, with no false positives. In our study, a total of 9 deaths occurred. Using the Kaplan-Meier method, the survival probability appeared to be slightly above 0.9 (95.5%), indicating that almost all patients survived past 72 hours after being diagnosed with CHD. Pulse oximetry is an effective, low cost and easy-to-use method and a useful tool to assess and lead to the diagnosis of CHD.

Morphological and phylogenetic (45S nrDNA+RPB1 gene) analyses of three glomoid spore-producing arbuscular mycorrhizal fungi revealed the presence of two new species be-longing to the genus Glomus in the family Glomeraceae. In the field, Glomus highlandensis sp. nov. was found in a saltmarsh of the Scottish Highlands and in maritime sand dunes of the Baltic Sea in Poland, both saline environments, while G. mongioie sp. nov. originates from the Italian Alps. Phylogenetic placement analysis using environmental sequences indicated that G. highlandensis could have likely worldwide distribution while G. mongioie seems to be a rare species in the world. The molecular and phylogenetic analysis provided important insights about the presence of ribosomal variants in Glomus, with potential negative implication in phylogeny and species recognition.

Published: April 2024

In this paper, we consider a class of bilevel programming problems (abbreviated as, BLPP). Exploiting the generalized approximate convexity assumptions, we investigate the relations among the solutions of approximate Minty (respectively, Stampacchia) type variational inequalities (abbreviated as, AMTVI (respectively, ASTVI)), and the local ϵ-quasi solutions of the BLPP. Moreover, by employing the generalized Knaster–Kuratowski–Mazurkiewicz (abbreviated as, KKM)-Fan’s lemma, we derive some existence results for the solutions of approximate variational inequalities (abbreviated as, AVI), namely, AMTVI and ASTVI. A non-trivial example is given to highlight the importance of the established results. To the best of our knowledge, there is no research paper available in the literature that establishes relationships between the AVI and the BLPP under the assumptions of generalized approximate convexity in terms of limiting subdifferentials.

Published: April 2024

Dealing with and maintaining high-quality standards in the design and construction phases is challenging, especially for on-site construction. Issues like improper implementation of building components and poor communication can widen the gap between design specifications and actual conditions. To prevent this, particularly for energy-efficient buildings, it's vital to develop resilient, sustainable strategies. These should optimize resource use, minimize environmental impact, and enhance livability, contributing to carbon neutrality by 2050 and climate change mitigation. Traditional post-occupancy evaluations, which identify defects after construction, are impractical for addressing energy performance gaps. A new, real-time inspection approach is necessary throughout the construction process. This paper suggests an innovative guideline for prefabricated buildings, emphasizing digital 'self-instruction' and 'self-inspection'. These procedures ensure activities impacting quality adhere to specific instructions, drawings, and 3D models, incorporating relevant acceptance criteria to verify completion. This methodology, promoting alignment with planned energy-efficient features, is supported by BIM-based software and Augmented Reality (AR) tools, embodying Industry 4.0 principles. BIM and AR bridge the gap between virtual design and actual construction, improving stakeholder communication and enabling real-time monitoring and adjustments. This integration fosters accuracy and efficiency, key for energy-efficient and Nearly Zero-Energy Buildings, marking a shift towards a more precise, collaborative, and environmentally sensible construction industry.

Published: April 2024

In the dynamic landscape of E-commerce, the proliferation of user-generated queries regarding products highlights the critical need for advanced automatic question answering (AQA) systems. These systems are instrumental in harnessing the vast array of information available online to deliver immediate and informative responses to potential buyers. Recognizing the complexity of such queries, which often require synthesis of reviews, product specifications, and responses to similar questions, we introduce a sophisticated model, the Comprehensive E-commerce Answer Generation System (CEAGS). This model adeptly navigates the challenges posed by irrelevant data and sentiment ambiguity in user-generated content. Our approach leverages a dual-phase process of relevance determination and sentiment clarity, setting the stage for a transformative response generation mechanism. Empirical analyses reveal the superiority of CEAGS, with our relevance assessment framework outstripping existing models by a notable margin in precision metrics, and our answer generation module achieving unprecedented gains in content preservation and coherence. Notably, CEAGS marks a pioneering contribution to the E-commerce domain by integrating disparate information sources to formulate responses that are not only accurate but also contextually rich and user-centric.
