Effects of the vertical and horizontal components of near-field ground motions on the seismic behavior of buildings considering soil-structure interaction
Authors: Farazmand Mehdi , Behnamfar Farhad , Aziminejad Armin
Published: December 2023

Three-dimensional nonlinear dynamic analyses of 3-, 6-, 9-, and 12-story steel buildings with special concentrically braced frame and special moment-resisting frame systems on soft and very soft soils are accomplished using OpenSees software. All buildings are modeled once as fixed-base and then taking nonlinear soil-structure interaction effects into account as a flexible-base case. They are excited under the effect of concurrent two and three translational components of near-field ground motions. Beams and columns considering
– ∆ effects are simulated using force-based beam-column elements with nonlinear material behavior at their two ends, and the finite-length plastic hinge approach is used to model the behavior of beam-column joints. By taking
– ∆ and imperfection effects into account, braces are modeled using displacement-based fiber elements with distributed plasticity behavior. The Beam-on-Nonlinear-Winkler-Foundation is used to model the nonlinear behavior of soil. Results show that the vertical component of earthquake can increase uplift and the total vertical force in the buildings up to about 50% and 80%, respectively. For the soft soil, the provision provided in ASCE code to consider the vertical component of ground motion in loading combinations for design turns out to be unconservative. Additionally, soil-structure interaction causes inter-story drifts to increase, especially for taller braced frames where the increase is up to 80% in the first story. Earthquake record characteristics can also have an increasing effect on the story drifts due to the flexibility of foundation, especially in the lower stories. In most cases, the maximum increase of the inter-story drift due to the base flexibility corresponds to the story where the same response is the lowest in the fixed-base condition. Using the obtained results, an equation is proposed to convert the lateral displacements of a fixed-base building to those in the flexible-base case.

Published: December 2023

Exploring the impact of gravity on daily upper-limb movements is crucial for comprehending the complexities of upper-limb impairments. The present study delves into the relationship between the gravitational force and the functional aspects of upper-limb mobility. Starting from 9 pick-and-place tasks, hand trajectories of 24 healthy subjects were acquired using a motion capture system. Five in-use and two novel kinematic metrics were extrapolated by such trends and tested across conditions. Results suggest movements performed against and propelled by gravity lead to statistically significant changes in motor behaviour in terms of planning, smoothness, efficiency, and accuracy of the movement, underlining the need of differentiating the study of such movements in impaired subjects.
Cerebral Vasomotor Reactivity Impairment in Resistant And Non-Resistant Hypertension: The Role Of The Autonomic Nervous System.
Authors: Miceli Giuseppe , Velardo Mariachiara , Casuccio Alessandra , Basso Maria Grazia , Tuttolomondo Antonino
Published: December 2023

Purpose: Hypertension reduces the ability of the vessel wall to constrict or dilate in response to one of many possible stimuli. Cardiovascular autonomic impairment contributes to the development of hypertension and it can influence cerebral vasomotor reactivity. Little is known about the effect of resistant hypertension. This study aims to analyze the role of sympathovagal imbalance in a cohort of patients with resistant (RH) and non-resistant hypertension (NRH) and its influence on cerebral vasomotor reactivity.
Methods: Forty consecutive hypertension patients, 20 with NRH and 20 with RH, underwenttime-domain heart rate variability analysis and transcranial color-coded Doppler at rest and during breath-holding maneuver to evaluate cerebral vasomotor reactivity.
Results: Hypertensive individuals presented statistically significant reduction of Breath Holding Index (BHI) and time-domain parameters (SDNN and SDANN) in comparison to the control group (BHI control group 1.32 ± 0.41 vs hypertensive patients 0.92 ± 0.65; p=0,018; SDNN control group 137.87± 27.5 vs hypertensive 108.44± 26.48; p <0.0001; SDANN control group 125.76± 24.96 vs hypertensive 87.65± 20.63; p<0.0001). RH patients presented a significant reduction in BHI (NRH group BHI 1.15 ± 0.65 vs RH group BHI 0.70 ± 0.58; p=0.027) and HRV parameters (SDNN in NRH group 118.48 ± 26.01 vs RH group 96.41 ± 23.47; p=0.015; SDANN in NRH group 95.09 ± 22.12 vs RH 80.21 ± 16.36; p=0.021).
Conclusions: Our results show that RH is associated with impairment of sympathovagal balance and cerebral vasomotor reactivity impairment. Autonomic dysfunction could be a concurrent cause of cerebral vasomotor reactivity impairment.
On the Evolution of Water Use Efficiency among Spanish Regions and its Determinants
Authors: Hernández Asensio Buendía , André Francisco Javier , SANTOS-ARTEAGA FRANCISCO JAVIER
Published: December 2023

Water scarcity is prone to be an important source of stress and conflict in the coming future. In the case of Spain, economic growth has relied, to a large extent, on some water-intensive sectors, such as construction, leisure, and agriculture. Spanish regions display important heterogeneities both in terms of water stress and economic structure. In this paper we analyze the determinants of water efficiency in Spain, differentiating by groups of agents (companies, households and municipalities) and paying particular attention to inter-regional differences and, most specifically, to the sectoral structure of these regions. Our objective is to identify the main socio-economic forces that explain the observed differences in the evolution of efficiency across regions. This is done by means of a panel data Tobit model combined with efficiency measures obtained using Data Envelopment Analysis (DEA) methodology. In turn, the efficiency measures are obtained under two different approaches: with and without considering the circular aspects of water. Our results suggest that considering these aspects tends to provide more credible and accurate efficiency measures as well as more robust results about the key driving factors to explain them.
Fair Link Prediction with Overlapping Groups
Authors: Pal Manjish , Sikdar Sandipan , Ganguly Niloy
Published: December 2023

In this paper, we consider the problem of ensuring fairness in graph data, more specifically the implementation of fair link prediction. In the context of link prediction in graphs, the fairness notions of demographic parity and equalized odds tries to ensure equal average linking probability and true positive rates across different demographic groups consisting of various node pairs. In this paper, we propose novel algorithms to implement these fairness notions while taking overlapping and intersectional groups into account that arise in the case of multiple sensitive attributes, unlike most of the existing methods which only consider a single sensitive attribute. Assuming that the link prediction model generates a prediction score for each node pair to form an edge, we formulate a convex optimization problem that minimizes the squared Euclidean distance between the original prediction scores and transformed scores, subject to the fairness constraints. The transformed scores are then utilized for fair link prediction. We refer to our overall framework as Fair Link Prediction for Graphs (FairLPG) and demonstrate our method's effectiveness on real-world datasets and graph neural network based link predictions models. It outperforms or performs competitively with existing methods both in terms of fairness and prediction accuracy. To the best of our knowledge, this work is the first to handle the case of intersectional sensitive groups in the graph setting.
Cooperation in green R&D and Environmental Policies: Tax or Standard
Authors: Cabon-Dhersin Marie-Laure , Raffin Natacha
Published: December 2023

In this article, we compare a tax and a standard as environmental tools depending on firms' R&D strategy and the government's ability to credibly commit to its policy. We consider a duopoly model where production is polluting and in an effort to mitigate emissions, firms invest in green R&D (in the presence of technological spillovers) either cooperatively or non-cooperatively. We explore two policy games in which the regulator establishes an emission tax or an emission standard either before or after firms engage in R&D. We endogenize both the firms' R&D strategy and the regulator's choice of policy instrument. We find that when firms choose not to cooperate, an emission standard is socially preferable. Conversely, a tax is the better choice when firms collaborate in green R&D.

Underwater Acoustic Target Recognition in Passive Sonar Using Spectrogram and Modified MobileNet Network Classifier
Authors: Akbarian Hassan , Sedaaghi Mohammad hosein
Published: December 2023

When the surface and subsurface floats move in the water, they emit sounds due to their propulsion engines as well as the rotation of their propellers. One of the best methods in underwater automatic target recognition (UATR) is to use deep learning to extract features and supervised train acoustic datasets that are used in the world’s naval forces. In this article, to achieve reliable results by deep learning methods, we collected the raw acoustic signals received by the hydrophones in the relevant database with the label of each class, and we performed the necessary pre-processing on them so that they become a stationary signal and finally provided them to the spectrogram system. Next, by using short-term frequency transformation (STFT), the spectrogram of high resonance components is obtained and used as the input of the modified MobileNet classifier for model training and evaluation. The simulation results with the Python program indicate that the suggested technique can reach a classification accuracy of 97.37% and a validation loss of less than 3%. In this research, a model has been proposed that, in addition to reducing complexity, has achieved a good balance between classification accuracy and speed.

3D Ising CFT and exact diagonalization on icosahedron: The power of conformal perturbation theory
Authors: Lao Bing-Xin , Rychkov Slava
Published: December 2023

We consider the transverse field Ising model in (2+1)D, putting 12 spins at the vertices of the regular icosahedron. The model is tiny by the exact diagonalization standards, and breaks rotation invariance. Yet we show that it allows a meaningful comparison to the 3D Ising CFT on \mathbb{R}× S^2ℝ×S2, by including effective perturbations of the CFT Hamiltonian with a handful of local operators. This extreme example shows the power of conformal perturbation theory in understanding finite N effects in models on regularized S^2S2. Its ideal arena of application should be the recently proposed models of fuzzy sphere regularization.
Temporal fluctuations of correlators in integrable and chaotic quantum systems
Authors: L. M. Lezama Talía , Bar Lev Yevgeny , Santos Lea F.
Published: December 2023

We provide bounds on temporal fluctuations around the infinite-time average of out-of-time-ordered and time-ordered correlators of many-body quantum systems without energy gap degeneracies. For physical initial states, our bounds predict the exponential decay of the temporal fluctuations as a function of the system size. We numerically verify this prediction for chaotic and interacting integrable spin-1/2 chains, which satisfy the assumption of our bounds. On the other hand, we show analytically and numerically that for the XX model, which is a noninteracting system with gap degeneracies, the temporal fluctuations decay polynomially with system size for operators that are local in the fermion representation and decrease exponentially in the system size for non-local operators. Our results demonstrate that the decay of the long-time temporal fluctuations of correlators cannot be used as a reliable metric of chaos or lack thereof.

Authors: Abbasova Sevinj
Published: December 2023

In conditions of fierce market competition, changing business environment, digitalization and remote workplaces, managerial accounting plays an increasingly important role in facilitating effective monitoring of a company’s activities, making optimal decisions, achieving its goals and development. The paper deals with identifying main trends of scientific and public interest in managerial accounting. Bibliometric analysis is made to determine interconnected clusters of multidisciplinary research in connection with which managerial accounting is considered, and to investigate dynamics in scientific interest on this issue based on tools of Scopus and WoS databases and VosViewer software (the sample of 10,495 articles, including 3,586 in Scopus for 1941–2022 and 6,909 in WoS for 1953–2022). These identified interconnections proved the significance of the managerial accounting component in the system of a company’s management, showed dominate place and described its multidimensionality. In particular, six defined clusters reflect key scientific and practical fields, goals, tasks, potential effects, and risks of managerial accounting. Based on analytical analysis using Google Trends (from 2004 to present) and Google Books Ngram Viewer (for 1800–2019), dynamics and trends of public interest on the issue of managerial accounting were also explored and visualized. The highest level of public interest in managerial accounting was indicated in Jordan, Bangladesh, Pakistan, Egypt, Thailand, Korea, the USA, and Canada.

Published: December 2023

Scientific evaluation of water resources metabolism efficiency (WME) has essential theoretical and practical value for regional water resources security and sustainable utilization. Based on the framework of the water resources metabolism process and construction of the indicator system of WME, the spatiotemporal variations of WME were analyzed using the weighted summation method in the Eastern, Central, and Western regions of China during the period from 1990 to 2020 with heterogeneous resource endowments. The exploratory spatial data analysis (ESDA) and spatial Durbin model were applied to analyze the spatial autocorrelation patterns and reveal spillovers of the WME. The results show that (1) The WME increased at different speeds in the Eastern, Central, and Western regions from 1990 to 2020 with heterogeneous resource endowment, and the spatial variation of WME in the Eastern and Central regions was significantly higher than in the Western regions. (2) The WME had significant spatial autocorrelation except in 2015, indicating obvious spatial agglomeration characteristics and spatial heterogeneity simultaneously. (3) The spatial spillover effects analysis indicated that the waste virtual recycling use ratio, the ratio of output virtual water and input virtual water, and industrial water ratio were the primary factors influencing WME.
“fotrica” como malha e possibilidade de entrelaçamento de memórias e trajetórias
Authors: Maffi Aline de Jesus
Published: December 2023

Este artigo busca propor alguns apontamentos sobre a fotrica. Nesse sentido, o texto apresenta perspectivas teóricas que fundamentam o que se tem chamado de fotrica, terminologia fundamentada no tensionamento da ideia de futrica, em um contexto de pesquisa no qual as imagens são associadas a relatos orais. Assim, a fotrica é concebida como uma malha relacional e um movimento de composição e articulação de memórias e trajetórias de mulheres que compartilham o mesmo contexto comunitário. Inserida em uma pesquisa fotobiográfica, a fotrica é pensada como um movimento relacional e conceitual que subsidiará o cruzamento de trajetórias de mulheres na pesquisa em andamento na Zona Rural de Londrina, Paraná, no Distrito de Maravilha. A partir disso, proponho que ela pode se caracterizar como uma composição contra-hegemônica que fundamenta o cruzamento e a articulação de fotobiografias e que se configura como um instrumento conceitual que pode visibilizar a reemergência de uma memória coletiva sobre uma territorialidade compartilhada.
I have self-compassion so I feel sexy! Sexual satisfaction and self-compassion effects on self-esteem and body esteem
Authors: Kocur Dagna , Jach Łukasz , Berek-Zamorska Magdalena , Kamińska Paulina
Published: December 2023

Body esteem, self-esteem, and sexual satisfaction influence people’s well-being so it is important to look for psychological factors that may contribute to their improvement. However, men and women differ in the factors that affect their body esteem, self-esteem, and sexual satisfaction. We analyzed links between men’s and women’s self-esteem, body esteem, sexual satisfaction, and self-compassion. The research involved 716 heterosexual participants (365 men and 351 women). All measured variables correlated positively; however, some correlations were stronger among women than among men. Mediation analyses revealed that sexual satisfaction directly affected women's body esteem but did not directly affect men's body esteem. Self-compassion and sexual satisfaction explained more variance in self-esteem and body esteem among women than among men. We explained observed differences in the contexts of the self-perception theory and the objectification theory.

Authors: Akraym Hatim. M. , Muniandy Ratnasamy , Jakarni Fauzan Mohd , Hassima Salihudin
Published: December 2023

Introduction:

Road safety plays a pivotal role in transportation infrastructure, as the quality of road surfaces is a crucial factor in ensuring safe driving conditions. One of the main indicators of road quality is the Mean texture depth (MTD), which greatly affects a vehicle's traction and skid resistance. Multiple methods are available for analyzing fabric depth, with the volumetric method, known as the sand patch test and standardized under ASTM E 965 – 96, being the traditional approach.

Aim:

This research aims to adapt a Sand Patch test procedure to evaluate surface texture depth on laboratory specimens with a 100 mm diameter and determine the required amount of sand, both in terms of weight and volume, to conduct this test effectively.

Methods:

To achieve this, the relationship between the amount of sand required and the sample size was determined. Two different types of asphalt mixtures were studied Stone Mastic Asphalt (SMA) and Asphalt Concrete (AC), with five gradation limits for each.

Results:

In the case of the AC10 mixture, the MTD ranged from 0.60 to 1.139 mm, while in SMA 20, the MTD ranged from 1.91 to 2.574 mm. These results are consistent with previous studies, confirming the reliability of the testing methodology, even when working with limited sample areas.

Conclusion:

In conclusion, the study highlights the potential simplicity and cost-effectiveness of using the Sand Patch micro-volume measurement method. When employed at the initial design stage, this method can provide valuable insights into surface texture, enhancing the design process and potentially further improving road safety.

Authors: Makarios Triantafyllos K. , Bakalis Athanasios P. , Athanatopoulou Asimina
Published: December 2023

Aims:

A new hybrid procedure that combines the Vlasov torsion theory with the Bernoulli bending theory is presented herein, to demonstrate qualitatively and quantitatively the operation of asymmetric folded plates with parallel edges, which are loaded with gravity static loads.

Background:

A recently proposed technique based on Vlasov torsion theory is used for the exact calculation of the Principal Elastic Reference System in a reinforced concrete folded plate having an asymmetric thin-walled open cross-section with parallel edges. Moreover, the warping moment (or bi-moment) concept of the Vlasov theory is combined with the pure-bending around two axes, according to the Bernoulli bending theory, to determine the normal stresses along the longitudinal dimension of the folded plate.

Methods:

Τhe warping properties of a thin-walled open cross-section are determined by calculating: (a) the elastic characteristics (elastic center, principal axes) of the section, (b) the principal start point, the sectorial coordinates, the wrapping moment of inertia and the wrapping stiffness of the section. Finally, the normal stresses along the longitudinal dimension are calculated considering the bi-axes flexure with the bi-moment phenomenon.

Results:

Τhe exact solution of normal stresses at the middle section of an examined folded plate along the longitudinal dimension is found by combining the Bernoulli bending theory for prismatic beams and the Vlasov torsion theory for thin-walled open sections.

Conclusion:

The current procedure can be used as a benchmark analysis method of asymmetric folded plates in order to evaluate the reliability of the results of various analysis F.E.M. software, covering an open issue of the structural analysis of special structures.

African Histories of Population and Health: A Plea for an Integrated Approach
Authors: Bras Hilde
Published: December 2023

Integrated approach needed to understand colonial legacy for demographic developments In order to understand the causes of population developments in Africa, it is necessary to examine the influences of the colonial era on the different parts of the continent. This is what Hilde Bras advocates in her inaugural lecture on Friday, May 26. She argues that the analysis of population figures – the field of historical demography – should go hand in hand with a more detailed study of medical and nursing practices – the field of medical and health history. The world's population has recently passed 8 billion people. Although growth is slowing, numbers will continue to rise at least until the end of this century. Most of this growth will take place in sub-Saharan Africa. Africa's population has increased from 179 million in 1950 to 1.2 billion today, and is expected to grow to 4 billion by 2100, a more than twenty-fold increase in 150 years. Not only this remarkable growth of the total population must be explained, but also the considerable variation therein across different parts of the continent. In her inaugural lecture, Bras argues that a long-term vision is essential to better understand population developments in Africa in all their variation. Understanding the influence of colonial governance and the Christian mission is necessary to explain the demographic transitions. This roughly concerns the period between the end of the nineteenth century and the beginning of the sixties, when most African countries were under European rule. Professor Bras advocates an integrated approach that combines the fields of 'historical demography' and the 'history of medicine, health and healing'. Figures acquire more analytical value when they go together with a more qualitative analysis of new sources such as mission diaries, interviews and photography through which the African inhabitants of the continent and their views on health and reproduction are given a voice and a face.

Background

Mental health disparities have been documented among lesbian, gay, and bisexual (LGB) adults in the United States. Substance use disorders and suicidal ideation have been identified as important health concerns for this population. However, the interrelationships among these factors are not well understood.

Objective

This study aims to investigate the interrelationships among mental health, substance use disorders, and suicidal ideation among LGB adults in the United States using a population-based statewide survey.

Methods

Our study was an observational cross-sectional analysis, and the data for this study were collected from a sample of LGB adults who participated in the statewide survey. The survey collected information on mental health, substance use disorders, and suicidal ideation using validated measures. Descriptive statistics and inferential data analysis were conducted to explore the interrelationships among these factors.

Results

The results showed that LGB adults who reported higher levels of depression and drug abuse and dependence also reported higher levels of suicidal tendency and mental illness. Inferential data analysis using χ2 tests revealed significant differences in depression score (χ22=458.241; P<.001), drug abuse and dependence score (χ22=226.946; P<.001), suicidal tendency score (χ22=67.795; P<.001), and mental illness score (χ22=363.722; P<.001) among the 3 sexual identity groups. Inferential data analysis showed significant associations between sexual identity and mental health outcomes, with bisexual individuals reporting the highest levels of depression, drug abuse and dependence, suicidal tendency, and mental illness.

Conclusions

This study provides important insights into the interrelationships among mental health, substance use disorders, and suicidal ideation among LGB adults in the United States. The findings underscore the need for targeted interventions and research aimed at addressing the mental health needs of sexual minority populations. Future research should aim to better understand the underlying mechanisms driving these disparities and develop culturally sensitive and tailored interventions that meet the unique needs of LGB individuals. Reducing stigma and discrimination against sexual minority populations is also crucial to improving their mental health outcomes.
Practical Considerations and Applied Examples of Cross-Validation for Model Development and Evaluation in Health Care: Tutorial
Authors: Wilimitis Drew , Walsh Colin G
Published: December 2023

Cross-validation remains a popular means of developing and validating artificial intelligence for health care. Numerous subtypes of cross-validation exist. Although tutorials on this validation strategy have been published and some with applied examples, we present here a practical tutorial comparing multiple forms of cross-validation using a widely accessible, real-world electronic health care data set: Medical Information Mart for Intensive Care-III (MIMIC-III). This tutorial explored methods such as K-fold cross-validation and nested cross-validation, highlighting their advantages and disadvantages across 2 common predictive modeling use cases: classification (mortality) and regression (length of stay). We aimed to provide readers with reproducible notebooks and best practices for modeling with electronic health care data. We also described sets of useful recommendations as we demonstrated that nested cross-validation reduces optimistic bias but comes with additional computational challenges. This tutorial might improve the community’s understanding of these important methods while catalyzing the modeling community to apply these guides directly in their work using the published code.
An indigenous psychology perspective for appropriate mental health services and research in Indonesia
Authors: Ranimpi Yulius Yusak , Hyde Merv , Oprescu Florin
Published: December 2023

Even though culture has been recognized and discussed by many scholars over decades in mainstream psychology, this aspect was treated only in terms of superficial manifestations and as a picture that represents different stages of social evolution or development. Indigenous psychology is an effort to rehash and refresh the importance of cultural aspects and their diversities in psychology and emplaces it as a vital way to understanding people from their perspective, in the real world. This approach believed that human being can construct their world. Knowledge and reality are psychological and social phenomena that are constructed by a human being. In terms of knowledge, indigenous psychology wants to claim that the truth is contextual-owned, experienced, believed, and lived by a human being. Especially in mental health and poverty issues and its interconnection in Indonesia must be treated as a psychological and social phenomenon that is socially constructed by people in their setting

Authors: Anas Mohammad
Published: December 2023

A well-known poet and activist named Kalki has successfully bridged the gap between art and activism with her poems by using a distinctive blend of visual storytelling. The paper examines the visual components that Kalki uses in her poems as effective vehicles for expressing social and political ideas. It does this by delving into the rich tapestry of her works. This study examines the complex interplay between art and activism in Kalki's work, giving insight into the poetry's ability to spark social change through in-depth analyses of a few poems. The poems selected for analysis include: “She”, “Piece by Piece”, and “Don’t tell that to me”.

La educación inclusiva y su configuración desde los imaginarios sociales y la hermenéutica reflexiva
Authors: Castro Cáceres Ricardo Andrés
Published: December 2023

Este artículo de reflexión académica ofrece una revisión general de la metodología comprensiva desde los imaginarios sociales y la hermenéutica reflexiva como camino metodológico posible para investigaciones aplicadas a la educación inclusiva. Se propone un enfoque y diseño desde la complementariedad. El análisis de la información se plantea en dos niveles de concreción, en el primer nivel se buscó la configuración y movilidad de los imaginarios sociales, en donde los mapas de coordenadas sociales fueron las herramientas utilizadas para visualizar los desplazamientos de las categorías sociales. En el segundo nivel, se profundizó en la comprensión de sentidos a partir de la hermenéutica reflexiva por medio del análisis estructural del discurso, desde donde se tomó la estrategia de estructura paralela.
Reflexión crítica como elemento de profesionalización de la formación inicial del profesorado de historia
Authors: Contreras Barrera Paz
Published: December 2023

La práctica reflexiva se considera como una pieza elemental para una profesionalización del profesorado. Se plantea que la reflexión crítica ayudaría a los docentes identificar las ideologías subyacentes a su propia práctica, y aún más en el caso de la enseñanza de la historia, puesto que conlleva prácticas discursivas que son constantemente mediadas por relaciones de poder. Sin embargo, diversas investigaciones dan cuenta que los profesores de historia no poseen habilidades necesarias para desarrollar procesos reflexivos. De esta manera, el objetivo del trabajo es reflexionar en torno a la necesidad de intencionar de manera sistemática la reflexión crítica en la formación inicial del profesorado de historia, como un elemento fundamental para su profesionalización. Finalmente, se concluye que la formación inicial del profesorado de historia, necesita integrar procesos formativos como la reflexión dialógica desde una mirada crítica.
