Experimental and numerical study on seismic behavior of precast shear walls assembled with a socket vertical joint

In the development of precast shear wall structures, reliable and efficient connections of precast units are crucial for their seismic behavior. Meanwhile, the heavy precast units using conventional concrete bring a low lifting efficiency. Considering these issues, the paper proposed a novel type of socket vertical joint for precast shear walls made of steel fiber reinforced lightweight aggregate concrete (SFRLAC). Sixteen socket connection specimens, with four socket depths (100 mm, 150 mm, 200 mm, and 250 mm) and two interface treatments (smooth and exposed aggregate), underwent interface bonding performance tests using uniaxial tensile testing and finite element (FE) numerical models to determine the appropriate socket depth. Three specimens were tested using the low-cyclic loading test, including two reinforced SFRLAC precast shear walls assembled with a socket vertical joint and a cast-in-place reinforced SFRLAC shear wall as a reference. The failure patterns and process of the shear walls were observed, while the load-displacement curves were obtained. Additionally, a parametric analysis of different influencing factors was conducted using finite element (FE) numerical models. This analysis studied the bearing capacity, energy dissipation capability, deformation ability, and stiffness degradation of the shear walls. Results indicate that when the precast shear walls were damaged, the socket vertical joint was integrity and failed in bending-shear. The three specimens exhibited fewer differences in seismic behavior with relatively full hysteretic curves. The seismic mechanisms of the shear wall assembled with a socket vertical joint were elucidated by analyzing the numerical distribution of stress in both SFRLAC and steel bars at different stress levels. Furthermore, an expansion analysis was conducted to assess the impact of axial load ratios and shear to span ratios on the seismic behavior of precast shear walls.

Understanding Social Media Information Sharing in Individuals with Depression: Insights from the Elaboration Likelihood Model and Schema Activation Theory.

How individuals engage with social media can significantly impact their psychological well-being. This study examines the impact of social media interactions on mental health, grounded in the frameworks of the Elaboration Likelihood Model and Schema Activation Theory. It aims to uncover behavioral differences in information sharing between the general population and individuals with depression, while also elucidating the psychological mechanisms underlying these disparities. A pre-experiment (N=30) and three experiments (Experiment 1a N=200, Experiment 1b N=180, Experiment 2 N=128) were executed online. These experiments investigated the joint effects of information quality, content valence, self-referential processing, and depression level on the intention to share information. The research design incorporated within-subject and between-subject methods, utilizing SPSS and SPSS Process to conduct independent sample t-tests, two-factor ANOVA analyses, mediation analyses, and moderated mediation analyses to test our hypotheses. Information quality and content valence significantly influence sharing intention. In scenarios involving low-quality information, individuals with depression are more inclined to share negative emotional content compared to the general population, and this tendency intensifies with the severity of depression. Moreover, self-referential processing acts as a mediator between emotional content and intention to share, yet this mediation effect weakens as the severity of depression rises. Our study highlights the importance of promoting viewpoint diversity and breaking the echo chamber effect in social media to improve the mental health of individuals with depression. To achieve this goal, tailoring emotional content on social media could be a practical starting point for practice.

Interest Rate Sensitivity of Depositors in Non-Financial Banks: A Case of an emerging Economy

This study uses 62 years of data, from 1960 to 2021, including variables like deposits, interest rates, GDP, and inflation, to investigate the link between interest rates and deposit behavior in non-Islamic banks in Pakistan. The study finds that interest rates have a big influence on deposit behavior using time series analytic techniques as unit root testing, cointegration analysis, and Vector Error Correction Model (VECM). More specifically, people's decisions to deposit money in non-Islamic banks are observed to be influenced by interest rate variations. The results highlight the importance of interest rate changes in influencing deposit behavior, showing how people choose which non-Islamic institutions to deposit money with. These findings have significance for financial institutions, policymakers, and economists in general. They provide important new information about the ways in which monetary policy choices affect deposit mobilization and liquidity conditions in the banking industry. The report also proposes directions for further investigation, including the possible examination of differences in deposit behavior between demographic groupings or geographical areas. To further help understand the dynamics at work, it also suggests examining how interest rates affect deposits in various sample configurations. This research advances theoretical frameworks in the field by shedding light on the complex interactions between interest rates and deposit behavior. It also offers stakeholders practical guidance on how to deal with the effects of interest rate dynamics on deposit mobilization and banking sector liquidity.

Cooperation in public goods experiments with random and finite stopping rules

AbstractWe contribute to a large literature that explores prosocial behavior in public goods experiments. We adopt an experimental design that allows full contribution to the public good to be sustained in equilibrium. We study the effect of the time horizon on a subject’s propensity to contribute to a public good by varying the stopping rule for the game. While many studies examine the effect of a random stopping rule in prisoner’s dilemma games, to our knowledge, only two other studies have directly compared behavior in public goods experiments with finite and random stopping rules. Consistent with existing studies, we find that contribution rates are similar across treatments in early rounds of play, and contribution rates are higher with random verses finite stopping rules in later rounds. Overall, we find significantly higher contributions to the public good when donors face a known probability of future interactions with the same group of participants compared to interactions with a finite endpoint. Further, the difference in cooperative behavior is driven primarily by the stopping rule, rather than the length of the game.

Baby Boomers and Their Voluntary Engagement: A Cohort Comparison Among the Middle-Aged and Older Population in Germany

The aim of this study is to compare the levels of volunteering by German baby boomers, who are currently in their fifties and sixties, to cohorts born earlier. Using data from the German Aging Survey (DEAS), logistic and negative binomial regressions were employed to analyze the prevalence and time contributions that baby boomers invest in volunteering. The study indicates a higher prevalence of volunteering by baby boomers compared with earlier-born cohorts and suggests that the large size of this cohort will imply high levels of volunteering that could increase even further as the cohort approaches retirement. Moreover, our findings suggest stability in voluntary time contributions by baby boomers compared with earlier-born cohorts; this contrasts with the existing research showing decreased overall time contributions to volunteering. The study underscores the importance of considering cohort-specific differences in voluntary engagement behavior to gain a deeper understanding of the dynamics of volunteering.

Intranasal delivery of paroxetine: A preclinical study on pharmacokinetics, depressive-like behaviour, and neurochemical sex differences

Treatment of major depressive disorder remains a major unmet clinical need. Given the advantages of intranasal administration for targeted brain delivery, the present study aimed at investigating the pharmacokinetics of paroxetine, after its intranasal instillation and assessing its potential therapeutic effect on female and male mice subjected to unpredictable chronic mild stress (UCMS) protocol.IN administration revealed direct nose-to-brain paroxetine delivery but dose- and sex-dependent differences. Pharmacokinetics was nonlinear and paroxetine concentrations were consistently higher in plasma and brain of male mice. Additionally, UCMS decreased animal preference for sucrose in both male and female mice following acute (p < 0.01) and chronic stress (p < 0.05), suggesting anhedonia. Both male and female mice exhibited depressive-like behavior in the forced swimming test. UCMS females displayed a significantly longer immobility time and shorter climbing time than the control group (p < 0.05), while no differences were found between male mice. Two weeks of paroxetine intranasal administration reduced immobility time and lengthened climbing and swimming time, approaching values similar to those observed in the healthy control group. The therapeutic effect was stronger on female mice.Importantly, melatonin plasma levels were significantly decreased in female mice following UCMS (p < 0.05), while males exhibited heightened corticosterone levels. On the other hand, treatment with IN paroxetine significantly increased corticosterone and melatonin levels in both sexes compared to healthy mice (p < 0.05).Intranasal paroxetine delivery undoubtedly ameliorated the behavioral despair, characteristic of depressive-like animals. Despite its efficiency in male and female mice subjected to UCMS, females were more prone to this novel therapeutic strategy.

Interactive effects between water temperature, microparticle compositions, and fiber types on the marine keystone species Americamysis bahia

Recently, there has been an increasing emphasis on examining the ecotoxicological effects of anthropogenic microparticles (MPs), especially microplastic particles, and related issues. Nevertheless, a notable deficiency exists in our understanding of the consequences on marine organisms, specifically in relation to microfibers and the combined influence of MPs and temperature.In this investigation, mysid shrimp (Americamysis bahia), an important species and prey item in estuarine and marine food webs, were subjected to four separate experimental trials involving fibers (cotton, nylon, polyester, hemp; 3 particles/ml; approximately 200 μm in length) or fragments (low-density Polyethylene: LDPE, polylactic acid: PLA, and their leachates; 5, 50, 200, 500 particles/ml; 1–20 μm). To consider the effects in the context of climate change, three different temperatures (22, 25, and 28 °C) were examined. Organismal growth and swimming behavior were measured following exposure to fragments and microfibers, and reactive oxygen species and particle uptake were investigated after microfiber exposure. To simulate the physical characteristics of MP exposure, such as microfibers obstructing the gills, we also assessed the post-fiber-exposure swimming behavior in an oxygen-depleted environment.Data revealed negligible fragment, but fiber exposure effects on growth. PLA leachate triggered higher activity at 25 °C and 28 °C; LDPE exposures led to decreased activity at 28 °C. Cotton exposures led to fewer behavioral differences compared to controls than other fiber types. The exposure to hemp fibers resulted in significant ROS increases at 28 °C. Microfibers were predominantly located within the gastric and upper gastrointestinal tract, suggesting extended periods of residence and the potential for obstructive phenomena over the longer term. The combination of increasing water temperatures, microplastic influx, and oxidative stress has the potential to pose risks to all components of marine and aquatic food webs.

Thinking you're different matters more for belonging than being different.

Belonging to a community is essential for wellbeing, but potentially unattainable for those dissimilar from a group. In the present work, we ask whether belongingness is better predicted by acting and thinking like peers or believing you act and think like peers. Students (N = 1181) reported their belonging and how much they, their friends, and an "average student" endorsed local behavioral norms and general values. We calculated difference scores for behaviors and values capturing perceived similarity to the average, actual similarity to the average, and accuracy around the norm. Key results indicate that perceived behavioral similarity to the average, when controlling for other differences, predicts belonging and most robustly mediates between identity and belonging. Using social network analysis, we find behavioral differences from friends are meaningfully linked to network density and racial homophily. Efficient interventions for enhanced belonging could highlight similarities between students and their peers.

Academic Struggle: A Case Study of Undergraduate First Year Medical Students

Academic struggle is a concern for students, medical schools, and the society. As academic struggle is not idiopathic and instantaneous, qualitative research could provide an in-depth understanding on why it occurs. This qualitative research aimed to explore reasons of failure among Malaysian Year 1 struggling medical students through the lens of Theories of Action. This study adopted a single, embedded case design. Six medical students repeating their Year 1 studies performed a written reflection describing their experiences and behaviours during Year 1. Then, semistructured interviews were conducted with each student, and data were analysed by two researchers. Independent analysis was compared, and discrepancies were resolved through discussions between the researchers. Each student narrative demonstrated difference in behaviours and experiences. Students showed limited learning engagement or demonstrated ineffective learning methods. Narratives indicated various reasons such as being overconfident or unmotivated to study for these behaviours. However, interpreting based on Theories of Action, the students’ failures could be explained by three types of invalid governing variables found in the data. Students may have performed their actions based on inadequate knowledge, possessing misbeliefs, or demonstrating no rationales at all. Invalid governing variables may have led to ineffective actions, and subsequently, resulting in unintended consequences. Hence, all students failed the mid-year and/or end-year assessments. Struggling students lacked the valid governing variables in rationalising their actions. Based on the Theories of Action, to deeply assess and alter their governing variables, struggling students are recommended to perform double loop learning.

Transport properties of ethylene glycol functionalized membranes exposed to nonaqueous electrolytes

Non-aqueous redox flow batteries (RFBs) are a promising technology to meet growing demand for grid-scale energy storage. Membrane separators, designed specifically for use with organic solvents, are necessary to advance non-aqueous RFBs. Herein, we report the development of a series of poly(phenylene oxide) (PPO) membranes functionalized with poly(ethylene glycol) (PEG) side chains to investigate the influence of PEG side chain length and degree of PEGylation on membrane transport properties. Increasing the degree of PEGylation generally led to increases in electrolyte uptake, hydroxy TEMPO permeability, and ionic conductivity likely caused by an increase in overall PEG content, as opposed to specific interactions caused by changing the degree of PEGylation. For membranes with similar PEG content, increasing the length of the PEG side chain resulted in decreases in electrolyte uptake, permeability, and conductivity possibly due to differences in the solvation behavior of the PEG chains with different lengths.

Assessing differences in the mechanical behaviour of loose cork granulates from virgin and reproduction cork

AbstractVirgin cork is a little-known, sustainable and relatively scarce raw material. However, its global output is expected to increase substantially as recent cork oak plantations are stripped for the first time. The work described here aimed to examine the factors underlying the mechanical properties of granulated cork, most particularly the type of cork (virgin or reproduction), and to develop a technique to deliver fast and accurate assessments of the effects of said factors. A batch of virgin cork was boiled, dried, ground and graded following standard granule classification procedures according to size and density. The resulting granulates were then compared with equivalent commercial-grade reproduction cork granulates. Physical variables (tapped density and moisture content) were measured and elastic recovery and Young’s modulus were used as proxies for mechanical properties. Image analysis was used to study the size, shape and colour of the cork particles. ANOVA results show significant effects of particle size, density class, type of cork and first and second order interactions between most variables. Density class clearly reached the highest level of significance, whereas the type of cork was less critical. A very strong correlation was found between granulates’ elastic recovery and their tapped density (R2 = 0.98; RMSE &lt; 1%). Likewise, greyscale imaging revealed a good adjustment between tapped density and grey level (R2 = 0.84; RMSE = 24 g·l−1). The primary conclusion was that the differences between virgin and standard cork granulates are small and should have no effect on less demanding applications. Image analysis is likely to prove useful in further, more in-depth studies.

Exploring the changes in travel behavior between the first and second waves of the COVID-19 pandemic in Dhaka

The COVID-19 outbreak created immense disruptions in our daily lives. Travel is one of the major areas severely impacted by the pandemic. Bangladesh experienced two waves of COVID-19 between March 2020 and July 2021. Although several studies focused on significant changes in the travel behavior of urban road users before and during the pandemic, hardly any research examined the differences between the two waves. Hence, it was important to study the differences in travel behavior between the two waves of the COVID-19 pandemic to understand how the effects of travel restrictions, health concerns, and the severity of the pandemic on people's travel decisions change over time. This study intends to investigate the changes in travel behavior between the first and second waves of the COVID-19 pandemic in Dhaka and the factors that influence these changes. Data were collected through online questionnaire surveys using the Google form. Voluntary response and convenience sampling techniques were used to collect responses from 447 people in Dhaka. Descriptive statistics and non-parametric tests were conducted to analyze the data. In addition, two multinomial logistic models were developed to identify the factors behind the changes in travel behavior. This study reveals that work and shopping trips increased, whereas work-from-home and online shopping somewhat decreased during the second pandemic wave compared to the first pandemic wave. Most non-car owners who reduced their use of public transportation during the first pandemic increased their use during the second wave. There was no significant increase in the use of active transport modes for work and shopping trips in Dhaka. The perceived risk of COVID-19 infection was relatively lower during the second wave, influencing the respondents to travel more frequently for work and shopping purposes. Ensuring more adaptive public transportation, flexibility to work from home, and creating supportive infrastructures for active transport modes might help to provide a safe, affordable, and efficient transportation system for all during the future waves of the pandemic and other unprecedented events.

Osteogenic differentiation of human mesenchymal stem cells on electroactive substrates

This study investigates the effect of electroactivity and electrical charge distribution on the biological response of human bone marrow stem cells (hBMSCs) cultured in monolayer on flat poly(vinylidene fluoride), PVDF, substrates. Differences in cell behaviour, including proliferation, expression of multipotency markers CD90, CD105 and CD73, and expression of genes characteristic of different mesenchymal lineages, were observed both during expansion in basal medium before reaching confluence and in confluent cultures in osteogenic induction medium. The crystallisation of PVDF in the electrically neutral α-phase or in the electroactive phase β, both unpoled and poled, has been found to have an important influence on the biological response. In addition, the presence of a permanent positive or negative surface electrical charge distribution in phase β substrates has also shown a significant effect on cell behaviour.

Puberty Blocker, Leuprolide, Reduces Sex Differences in Rough-and-Tumble Play and Anxiety-like Behavior in Juvenile Rats.

We examined the effect of the puberty blocker, leuprolide acetate, on sex differences in juvenile rough-and-tumble play behavior and anxiety-like behavior in adolescent male and female rats. We also evaluated leuprolide treatment on gonadal and pituitary hormone levels and activity-regulated cytoskeleton-protein messenger RNA levels within the adolescent amygdala, a region important both for rough-and-tumble play and anxiety-like behavior. Our findings suggest that leuprolide treatment lowered anxiety-like behavior during adolescent development, suggesting that the maturation of gonadotropin-releasing hormone systems may be linked to increased anxiety. These data provide a potential new model to understand the emergence of increased anxiety triggered around puberty. Leuprolide also reduced masculinized levels of rough-and-tumble play behavior, lowered follicle-stimulating hormone, and produced a consistent pattern of reducing or halting sex differences of hormone levels, including testosterone, growth hormone, thyrotropin, and corticosterone levels. Therefore, leuprolide treatment not only pauses sexual development of peripheral tissues, but also reduces sex differences in hormones, brain, and behavior, allowing for better harmonization of these systems following gender-affirming hormone treatment. These data contribute to the intended use of puberty blockers in stopping sex differences from developing further with the potential benefit of lowering anxiety-like behavior.

Dueling COVID-19 misinformation: Perceptions and behavior of the rural population from South Asian countries

This multi-lingual study presents the awareness, perceptions, and behavior regarding COVID-19 “misinformation” and “fake news,” among the rural population of the South Asian (SA) countries of Bangladesh, India, and Pakistan. The survey questionnaire was distributed to a convenient sample of 400 respondents from the three most populated SA countries selected due to their shared socio-cultural history; limited by fund availability and travel restrictions due to the prevailing lockdowns during the data collection period of early 2022. Results indicate that 92.98% of the participants perceived the presence of COVID-19 misinformation to varying degrees around them with less than 10% finding it easy to verify the accuracy of the information. The results indicate that the participants initially believed the made-up news and information to be true and then experienced fear or uncertainty upon realizing that it was fake. Results further show significant differences in perception and behavior when analyzed with the parameters of gender, age, education, and religion. Our study highlighted that female respondents perceived less than male respondents that fake news was around them, and younger participants of the study had less perception of the presence of fake news around them. The present study also found that the education level of respondents is a strong predictor of their perception of COVID-19 misinformation. Respondents with high school degrees perceived less made-up news and information than associate and master-level degree holders. The findings indicate a lack of media literacy, with a vast majority of individuals being susceptible to false information. The findings of the study will help healthcare professionals, information professionals, social workers, extension workers, and policymakers to deal with the Infodemic and further also assist in designing shared health information literacy programs across the region.

An exploration of racial and ethnic differences in paraphilic interests and behaviours among a nonoffending sample

ABSTRACT Paraphilic interests are often associated with sexual offending and recidivism, and therefore, accurately identifying paraphilias is crucial. Recently, there has been increased recognition of diversity as it relates to sexual offending; however, few studies have examined race/ethnicity as it pertains to paraphilias, and those that have are often limited to forensic samples. Given that important decisions such as post-incarceration civil confinement are, in part, based upon paraphilia diagnoses, information concerning population base rates of paraphilic interests and behaviours, and how they may vary by race/ethnicity, is needed. The current study explored racial/ethnic differences in paraphilic interests/behaviour among a non-offending U.S. sample of 2,292 participants over age 18, using a measure adherent to the DSM-5-TR paraphilia criteria. The findings revealed group differences, highlighting the need for further research examining these differences. PRACTICE IMPACT STATEMENT The results provide information regarding potential racial/ethnic differences in self-reported paraphilic interests and behaviour among a general population, non-offending sample. This information will assist clinicians who evaluate and diagnose paraphilic interests and disorders and represents a contribution to the larger goal of informing best practices for culturally competent risk assessment and evaluation, treatment, and prevention of sexual abuse.

Habitat variety and behaviour of the Sanderling (Calidris alba) in an urban neotropical coastal wetland

Sanderling Calidris alba is a migratory coastal bird species whose populations are affected by climatic and anthropogenic issues. Additionally, its behavioural patterns depend on habitat variety. The aim of this study was to evaluate the variation in the frequency and duration of C. alba behaviour in relation to habitat variety in a Peruvian coastal wetland. Based on types of behaviour recorded in a previous study of C. alba during August and September 2019 at low, mid and high tide periods in three habitats of the Coastal Wetland Poza La Arenilla (HCPA) (La Punta, Callao, Peru), differences and diversity in the frequencies and durations of such behaviour between habitats were assessed according to tide condition. Additionally, a correlation analysis between the duration and frequency of behaviour for each habitat according to tide condition was conducted. General differences in behaviour (frequency and duration) between habitats were found, although there was a high similarity of behaviour between areas particularly when mid- and high tide levels were present. The greatest diversity of behaviour, both in frequency and duration, was observed generally during mid-tide conditions in rocky habitats. In most cases, there was a high correlation between the frequency and duration of behaviour for habitats according to tide condition. It is concluded that mid-tide conditions are associated with greater availability of soft substrates, favouring a wide variety of types of behaviour for C. alba, including behaviour related to foraging and locomotion.

Exploring the comorbidity between internalizing/externalizing dimensions and cognitive disengagement syndrome through twin studies: a narrative review

Twin studies are cutting-edge design methodologies proper to behavioral genetics that aim to investigate how the interplay between genetic and environmental factors can concur to explain individual differences in psychopathology, temperamental traits, and behavior. This particular research design has been widely applied to the study of comorbidity between internalizing (INT) and externalizing (EXT) symptoms, especially in childhood and adolescence. Notably, the high co-occurrence of symptoms of both these diagnostic domains has led to the hypothesis that at their basis, there might be one single latent common susceptibility factor, namely p factor. Twin studies have contributed to marking a relevant turning point in this regard by highlighting the consistent genetic nature of this factor. In light of these premises, the present narrative review aims to outline the path for future twin studies in investigating the comorbidity between Cognitive Disengagement Syndrome (CDS) and INT-EXT disorders, examining the evidence supporting this need and its clinical implications. Since CDS has not been recognized as a stand-alone syndrome until very recently, research on this condition is still in its infancy and the etiological factors at the basis of its comorbidity with INT-EXT are still unclear. Being aware of the causal factors underneath the comorbidity between INT-EXT might pave the way for improving assessment diagnostic procedures as well as setting up preventive interventions for CDS.

Can Internet Use Narrow the Gap between Farmers’ Willingness and Behavior in Waste Classification? Empirical Evidence from Rural Areas in Jiangsu Province, China

Household waste classification and treatment are important for environmental protection and sustainable development. The Logit model is used to analyze differences in farmers’ willingness and behavior regarding waste classification based on data from the China Land Economic Survey. Key findings include the following: (1) There is an evident discrepancy between waste classification willingness and action among rural residents. Despite nearly 90% of the sampled farmers expressing a willingness, nearly 40% do not practice waste classification. (2) Internet usage significantly reduces the discrepancy between farmers’ willingness and actual waste classification practices. This observation is valid even after robustness checks and endogeneity discussions. (3) There is a partial mediating effect between ecological awareness and knowledge perception on farmers’ willingness and behavior differences, which accounts for 12.9% and 52.6%, respectively, of the total impact. Notably, institutional limitations amplify the negative influence of Internet use on this discrepancy. (4) According to heterogeneity analysis, Internet use has a greater negative impact on farmers’ willingness and behavior in waste classification in suburban villages and villages with environmental governance projects. This study proposes policy suggestions such as strengthening the construction of digital infrastructure in rural areas, enhancing the promotion and training of waste classification among farmers, and improving incentives and restraint mechanisms for rural household waste classification.

EVALUASI PERILAKU HARIAN LUTUNG JAWA (Trachypithecus auratus E. Geoffroy Saint-Hilaire 1812) PASCA PELEPASLIARAN DI GUNUNG BIRU BATU JAWA TIMUR

The Mount Biru protect forest is still maintained the biodiversity so that it is able to support a variety of animals in it, one of which is a habitat for the release of the javan langurs group (T. auratus). This study aims to determine the daily behavior of the javan langur after rehabilitation and release to evaluate the development of population behavior and barriers in the same group since 2014. The study used a focal animal sampling method combined with scan sampling to observe daily behavior (eating, social, resting, and moving) one female javan langur released in 2014. It was observed that post-release individuals had higher resting activities (38.91%) and the lowest allo-grooming social activities (5.08%). The results of the different test calculations using Chi Square can be concluded that there are significant differences in the daily behavior of the Javan langur after release in 2015, 2019 and 2021.
