Aggressive Behavior in Older Preschoolers: Implications, Causes, and Prevention Strategies

Aggressive behavior in older preschoolers has long been a nuisance to kindergarten teachers and parents, and it is a common yet difficult problem in society. This study recorded the proportion, context, and reasons for aggressive behavior in older preschoolers at the Tianfu New Area Experimental Kindergarten in Chengdu. Combining the physical and mental development patterns of older preschoolers, methods such as observation records and situational analysis were used. Through real confrontation, observation, analysis, and exploration, effective ways to reduce and correct aggressive behavior in older preschoolers were found, with the aim of helping teachers cope with such behaviors.

Spatial maps in piriform cortex during olfactory navigation.

Odors are a fundamental part of the sensory environment used by animals to inform behaviors such as foraging and navigation1,2. Primary olfactory (piriform) cortex is thought to be dedicated to encoding odor identity3-8. Here, using neural ensemble recordings in freely moving rats performing a novel odor-cued spatial choice task, we show that posterior piriform cortex neurons also carry a robust spatial map of the environment. Piriform spatial maps were stable across behavioral contexts independent of olfactory drive or reward availability, and the accuracy of spatial information carried by individual neurons depended on the strength of their functional coupling to the hippocampal theta rhythm. Ensembles of piriform neurons concurrently represented odor identity as well as spatial locations of animals, forming an "olfactory-place map". Our results reveal a previously unknown function for piriform cortex in spatial cognition and suggest that it is well-suited to form odor-place associations and guide olfactory cued spatial navigation.

Finite Element Modeling of Beam-to-Column Steel Timber Composite Joints with Different Parameters

This study presents a comprehensive three-dimensional finite element modeling and parametric analysis of composite beam-to-column joints in steel–timber composite structures. The investigation encompassed a variety of shear connector configurations, end plate designs, and bolt dimensions, aiming to elucidate their respective influences on the structural performance and behavior of these joints. Through meticulous numerical simulation, this research sought to enhance the understanding of the interactions and load transfer mechanisms within composite connections, thereby contributing to the optimization of design practices in the field of structural engineering. The load–displacement relationship for timber–steel composite joints subjected to monotonic loading was investigated using ABAQUS 6.14 software. This study systematically analyzed the effects of various parameters, including different configurations of shear connectors, end plate thicknesses, and bolt dimensions, on the overall performance of the joints. Through this comprehensive numerical analysis, the research aimed to provide deeper insights into the mechanical behavior and structural integrity of these composite connections under the applied loading conditions. A non-linear finite element model of timber was developed and verified with the results of the experiment in this study. The findings are discussed in detail, highlighting the intricate relationships between the selected parameters and their respective effects on the performance and overall stability of the composite connections. This thorough evaluation aimed to enhance the understanding of how these variables interact within the context of composite joint design and behavior. Finally, design recommendations for composite structures, such as the dimensions of the bolt, end plate thickness, and different sizes of shear connectors are provided.

User evaluation of a tiny house design through eye-tracking-integrated virtual reality: the role of sense of presence, visual behaviour and informative context

AbstractVirtual Reality is used in design for both supporting design reviews and interacting with products being designed. The interactions Virtual Reality enables are often found engaging and this might affect product evaluation, as experiencing a virtual environment can be the prevalent element of an experience. This paper investigated to what extent product evaluations are affected by the sense of presence enabled by Virtual Reality, the duration of interactions with the whole products and its features, and the product information provided after exposure to the virtual environment. These effects were tested through an experiment involving the virtual tour of a tiny house whose interior was extracted through 360° images, which represents an element of originality of the paper, followed by administering participants informative stimuli. All these phases were supported by eye-tracking, also thanks to the use equipment combining Virtual Reality and eye-tracking, hitherto poorly used in design research, in the first part of the experiment. Based on the experiment results, the effects studied were limited to the gazing of few design elements on some product evaluation dimensions. These findings suggest that Virtual Reality can provide a strong product perception irrespective of sense of presence and other phenomena taking place during product interaction. This is particularly stressed by the failure of informative stimuli to make experiment participants modify the initial evaluations made just after the virtual tour. Overall, the outcomes of this study encourage the use of Virtual Reality for design interaction tasks, especially in relation to environments and building interiors.

Kinematically distinct saccades are used in a context-dependent manner by larval zebrafish

Saccades are rapid eye movements that are used by all species with good vision. In this study, we set out to characterize the complete repertoire of larval zebrafish horizontal saccades to gain insight into their contributions to visually guided behavior and underlying neural control. We identified five saccade types, defined by systematic differences in kinematics and binocular coordination, which were differentially expressed across a variety of behavioral contexts. Conjugate saccades formed a large group that serves at least four functions. These include fast phases of the optokinetic nystagmus, visual scanning in stationary animals, and shifting gaze in coordination with body turns. In addition, we discovered a previously undescribed pattern of eye-body coordination in which small conjugate saccades partially oppose head rotation to maintain gaze during forward locomotion. Convergent saccades were coordinated with body movements to foveate prey targets during hunting. Detailed kinematic analysis showed that conjugate and convergent saccades differed in the millisecond coordination of the eyes and body and followed distinct velocity main sequence relationships. This challenges the prevailing view that all horizontal saccades are controlled by a common brainstem circuit and instead indicates saccade-type-specific neural control.

Paying less as a signal of competence

AbstractPast research suggests that cost‐saving behaviors such as couponing can trigger negative trait perceptions (e.g. that the consumer is being miserly), and consumers purchasing gifts may avoid use of coupons so as not to appear ungenerous. In contrast, we contend that cost‐saving can also send a positive signal. In five studies we show that cost‐saving enhances perceptions of consumer competence and financial management skills, which, in turn, can lead to more favorable brand perceptions. Using costly signaling theory, we further identify two boundary conditions for these signals to be perceived as genuine: (a) absence of ulterior motives (e.g., sponsored social media posts that diminish the authenticity of the signal) and (b) the presence of the quality being signaled (as higher‐class consumers are typically seen as competent). Our findings extend the scope of signaling theory to consumer behavior contexts, showing that costly signals must honestly convey positive qualities.

The relationship between morningness-eveningness and naturalness bias

ABSTRACT The naturalness bias in which people perceive natural items to be safer, healthier, and better than synthetic alternatives has been found to be associated with numerous individual difference variables (e.g. connectedness to nature and religiosity). However, no research has examined the role of morningness-eveningness in influencing preferences for naturalness. Here, we propose that evening individuals may exhibit a weaker preference for naturalness compared to morning individuals due to their greater exposure to artificial lighting, technology, and stimuli. To systematically test our theoretical perspective, we conducted three complementary and high-powered studies. In an online survey (Study 1), student participants with a stronger evening orientation displayed a diminished preference for natural drugs compared to those with a morning orientation. Using a sample of community adults, Study 2 replicated the findings of Study 1 in a real-world, behavioral context. Study 3 examined the relationship between morningness-eveningness and preference for naturalness within the domain of beverages. The results revealed that individuals with an evening-orientation had decreased odds of selecting natural water without minerals. Taken together, the findings suggest that an individual’s diurnal preference toward eveningness may have implications for their bias toward and perception of naturalness across various domains.

Vocalisation in wild-living mountain gazelles (Gazella gazella): structure and context of acoustical signals

Abstract Describing vocalisations of species in the wild is an important step to understanding their function. A wild-living population of mountain gazelles (Gazella gazella) was monitored in Israel, using camera traps, thereby providing a first detailed description of the acoustic repertoire. We described six acoustical signals that were either reported by previous authors or that were hitherto not reported. Acoustic signals were categorised according to behavioural context as alarm calls, courtship calls or threat calls and — if possible — characterised by four acoustic variables, i.e., duration, maximum amplitude frequency, three power quartiles and fundamental frequency. Vocalisations were illustrated as spectrograms supplemented by full video sequences to show the acoustical signal in its environmental, social, and behavioural context. Given the rather inconspicuous character of many acoustic signals, we proposed further in-depth studies of vocalisation in mountain gazelles and other Antilopine species to unravel new insights into their behaviour and social organisation.

Examining the Attitude–Behavior Gap in EU Ecolabel Adoption: A Mediation Path Analysis

The EU Ecolabel, established in 1992, aims to promote sustainable consumption, yet a significant gap persists between consumers’ positive environmental attitudes and their actual purchasing behavior of ecolabeled products. This study examines the attitude–behavior gap in EU Ecolabel adoption across Europe, leveraging data from the 2023 Eurobarometer survey with 26,630 valid responses from all EU member states. Using mediation path analysis, the research investigates the factors mediating the relationship between environmental knowledge and purchasing behavior, including environmental attitude, ecolabel trust, and environmental concern. The study applies an integrated theoretical framework combining the Knowledge–Attitude–Behavior model and Attitude–Behavior–Context theory to explain the complexities of consumer behavior towards ecolabeled products. The findings reveal the interplay of direct and indirect effects among ecolabel knowledge, trust, environmental concern, attitude, and buying behavior, while also considering demographic factors’ influence such as age, gender, education level, and residential setting. The research provides a comprehensive cross-country analysis within the EU, offering insights into bridging the attitude–behavior gap and enhancing the adoption of eco-friendly products. The results have significant implications for policymakers, marketers, and researchers in promoting sustainable consumer behavior, improving environmental label effectiveness, and developing targeted interventions to increase ecolabel adoption rates.

Learning to use landmarks for navigation amplifies their representation in retrosplenial cortex.

Visual landmarks provide powerful reference signals for efficient navigation by altering the activity of spatially tuned neurons, such as place cells, head direction cells, and grid cells. To understand the neural mechanism by which landmarks exert such strong influence, it is necessary to identify how these visual features gain spatial meaning. In this study, we characterized visual landmark representations in mouse retrosplenial cortex (RSC) using chronic two-photon imaging of the same neuronal ensembles over the course of spatial learning. We found a pronounced increase in landmark-referenced activity in RSC neurons that, once established, remained stable across days. Changing behavioral context by uncoupling treadmill motion from visual feedback systematically altered neuronal responses associated with the coherence between visual scene flow speed and self-motion. To explore potential underlying mechanisms, we modeled how burst firing, mediated by supralinear somatodendritic interactions, could efficiently mediate context- and coherence-dependent integration of landmark information. Our results show that visual encoding shifts to landmark-referenced and context-dependent codes as these cues take on spatial meaning during learning.

The Rpfor gene modulates the locomotory activity and host-seeking behaviour of Rhodnius prolixus.

The molecular bases of animal behaviour are intricate due to the pleiotropic nature of behaviour-modulating genes, which are often expressed across multiple tissues. The foraging gene (for) encodes a cGMP-dependent protein kinase (PKG), pivotal in regulating downstream target proteins through phosphorylation. In insects, for has been implicated in various behavioural contexts and physiological processes regarding searching for food. Rhodnius prolixus, a hematophagous bug that transmits Trypanosoma cruzi, the causative agent of Chagas disease, exhibits specific activity patterns associated with its hematophagous behaviour. Our previous work demonstrated a correlation between locomotor activity profiles and the expression of Rpfor, suggesting its involvement in modulating triatomine locomotion. In this study, we investigated the impact of Rpfor knockdown on locomotory activity, host-seeking behaviour, feeding performance and lipid metabolism in R. prolixus nymphs. Using RNA interference, we achieved a significant reduction of Rpfor expression in both the brain and fat body of R. prolixus nymphs. Knocked-down nymphs exhibited diminished non-oriented locomotory activity compared with controls, without altering the characteristic bimodal pattern of activity. Additionally, they displayed an increased tendency to approach a host, suggesting a role for Rpfor in modulating host-seeking behaviour. Feeding performance and lipid metabolism remained unaffected by Rpfor knockdown. Our findings underscore the multifaceted role of Rpfor in modulating locomotor activity and host-seeking behaviour in R. prolixus nymphs, shedding light on the molecular mechanisms underlying their hematophagous behaviour and potential implications for disease transmission. Further research is necessary to elucidate the intricate interplay between Rpfor expression, behaviour and physiological processes in triatomine bugs.

Maternal rejection but not protectiveness predicts juvenile Japanese macaque behavior without direct maternal influence.

Primates show large interindividual variability in the character and quantity of interactions between mothers and their immature offspring. Multiple studies have documented associations between maternal behavior and the occurrence or frequency of certain behaviors among offspring, but it remains unclear whether and how early maternal interactions generally affect behavioral development in offspring. We followed two wild groups of Japanese macaques on Yakushima island and investigated the relationship between maternal behavior and several types of behavior performed by 35 juvenile offspring. We further asked if the impact of maternal behavior on juvenile behavior persists regardless of the distance between mother and offspring, testing whether the influence extends beyond cases when the mother is nearby. We found that juveniles whose mothers frequently rejected them approached and played with others more often, independent of their mother's presence. Juveniles of more protective mothers were in proximity to fewer other individuals and played less, but only if their mothers were nearby. Maternal rejection appears to exert a generalized effect on offspring behavior that endures when mothers are absent. In contrast, effects of maternal protectiveness may be temporary and/or reflect direct maternal influences, such as active intervention in offspring interactions, or effects of the mother's own social relationships on offspring interactions. Our results suggest that understanding how maternal behavior affects offspring development requires paying attention to the context of juvenile behavior, including the mother's distance from her offspring.

A Novel Quadrant Spatial Assay Reveals Environmental Preference in Mouse Spontaneous and Parental Behaviors

Environmental factors have well-documented impacts on brain development and mental health. Therefore, it is crucial to employ a reliable assay system to assess the spatial preference of model animals. In this study, we introduced an unbiased quadrant chamber assay system and discovered that parental pup-gathering behavior takes place in a very efficient manner. Furthermore, we found that test mice exhibited preferences for specific environments in both spontaneous and parental pup-gathering behavior contexts. Notably, the spatial preferences of autism spectrum disorder model animals were initially suppressed but later equalized during the spontaneous behavior assay, accompanied by increased time spent in the preferred chamber. In conclusion, our novel quadrant chamber assay system provides an ideal platform for investigating the spatial preference of mice, offering potential applications in studying environmental impacts and exploring neurodevelopmental and psychiatric disorder models.

The Influence of Psychosocial Factors on the Popularity of Consumer Behavior

This essay delves into the profound impact of psychosocial factors on the emergence and diffusion of popularity, highlighting the intricate dynamics that govern consumer preferences. The herding effect, wherein individuals follow the majority, is a pivotal force shaping trends. Consumers are drawn to products or ideas with widespread acceptance, influenced by the collective consciousness of society. Aesthetics also wield significant influence, as visually and sensory pleasing attributes enhance a product's appeal, contributing to its popularity. Moreover, the compelling drive of social affiliation emerges as a powerful force shaping consumer choices. The inherent human need for belonging and acceptance influences product selection, amplified by social media platforms where individuals showcase preferences, creating virtual spaces for exchanging ideas and trends.In conclusion, the interplay of psychosocial factors, including the herding effect, aesthetic appeal, and social affiliation, profoundly shapes the landscape of consumer popularity. Recognizing and understanding these influences are crucial for businesses, marketers, and policymakers navigating the ever-evolving societal context of consumer behavior. By acknowledging the potency of these factors, stakeholders can strategically leverage them to anticipate and respond to shifts in consumer preferences, ultimately fostering successful engagement in the dynamic marketplace.

Acoustic Communication in Dendroctonus adjunctus Blandford (Curculionidae Scolytinae): Description of Calls and Sound Production Mechanism.

The acoustic communication system (ACS) in bark beetles has been studied mainly in species of the genera Dendroctonus, Ips and Polygraphus. Specifically, ACS of the roundheaded pine beetle, Dendroctonus adjunctus, has been little studied. In this study, we described the stridulatory apparatus of this beetle using optical and scanning electron microscopy and recorded the call types produced by males in three behavioral contexts: stress, female-male-, and male-male interactions. From the spectrograms and waveforms, call types, as well as temporal (tooth strike, tooth strike rate, and intertooth strike interval) and spectral features (minimum, maximum and dominant frequency), were determined. Males have a functional elytro-tergal stridulatory apparatus-females do not-consisting of a file for the pars stridens and two lobes for the plectrum. Most of spectro-temporal features were statistically different between single- and multi-noted calls and across the three behavioral contexts. In the male-male interaction, a new type of call named "withdrawal" was produced by the male withdrawing or fleeing. Our results suggest that the spectro-temporal features of single- and multiple-noted calls in the three behavioral conditions are specific and different from each other. Yet, the combination of single and multiple calls determines an overall calling pattern characteristic of the tested behaviors and, therefore, is species-specific.

Selective consolidation of learning and memory via recall-gated plasticity.

In a variety of species and behavioral contexts, learning and memory formation recruits two neural systems, with initial plasticity in one system being consolidated into the other over time. Moreover, consolidation is known to be selective; that is, some experiences are more likely to be consolidated into long-term memory than others. Here, we propose and analyze a model that captures common computational principles underlying such phenomena. The key component of this model is a mechanism by which a long-term learning and memory system prioritizes the storage of synaptic changes that are consistent with prior updates to the short-term system. This mechanism, which we refer to as recall-gated consolidation, has the effect of shielding long-term memory from spurious synaptic changes, enabling it to focus on reliable signals in the environment. We describe neural circuit implementations of this model for different types of learning problems, including supervised learning, reinforcement learning, and autoassociative memory storage. These implementations involve synaptic plasticity rules modulated by factors such as prediction accuracy, decision confidence, or familiarity. We then develop an analytical theory of the learning and memory performance of the model, in comparison to alternatives relying only on synapse-local consolidation mechanisms. We find that recall-gated consolidation provides significant advantages, substantially amplifying the signal-to-noise ratio with which memories can be stored in noisy environments. We show that recall-gated consolidation gives rise to a number of phenomena that are present in behavioral learning paradigms, including spaced learning effects, task-dependent rates of consolidation, and differing neural representations in short- and long-term pathways.

Analysis of the acceptance of E-learning platform (SIDEK-Edu) among high school students with UTAUT2-TOE approach: implications for digital learning

PurposeThe purpose of this study is to examine the acceptance factors of e-learning among students in high schools. In this study, researchers used a combination of system acceptance models, namely UTAUT2 and TOE. The UTAUT2 framework is used to explore technology acceptance from the context of individual behavior, while TOE is used to understand technology acceptance from the organizational context based on the perspective of students, as it results in a better choice to anticipate the relationship between the acceptance of technological innovation in high schools.Design/methodology/approachThis study used quantitative methods. The sample in this study amounted to 212 people who were high school students who had just tried using SIDEK-Edu. This study uses Partial Least Square-Structural Equation Modeling (PLS-SEM) to analyze the measurement model and structural model with WarpPLS version 6 software.FindingsBased on the results of the tests carried out, out of a total of 16 hypotheses, 6 hypotheses were accepted and 10 hypotheses were rejected. Research findings from the individual context show that performance expectancy, social influence, and learning value have a positive and significant effect on behavioral intention to use SIDEK-Edu innovation technology. Furthermore, judging from students' perceptions in the organizational context, only relative advantage has a positive and significant effect on behavioral intention, while compatibility, ICT resources, and competitive pressure do not.Research limitations/implicationsThe limitations of this research are that this research uses a homogeneous sample of high school students, this research only focuses on the high school level, this research is limited to the dominant variables in measuring the acceptance of SIDEK-Edu innovation technology.Practical implicationsInput to the high school, both the organization, teachers, and also decision makers in the organization. This makes it easier for all parties to design and implement the system they have so that it is as expected, In addition, the existence of SIDEK-Edu also provides a new learning method experience in learning accounting which is very beneficial for high school students, especially vocational high school.Originality/valueSIDEK-Edu is a new innovative technology to research and is an LMS that focuses on accounting learning (theory room and practice room in one learning media). In addition, the model used in the study is a combination of models (UTAUT2-TOE) to indentify e-learning acceptance.

Exploring the impact of goals and motivation on young consumers’ sustainable plastic management behavior using the Theory of Reasoned Goal Pursuit

Despite literature suggesting the importance of goals and motivation in pro-environmental behavior, its implication for predicting consumers’ sustainable plastic management behavior (SPMB) is limited. This paper adopted the Theory of Reasoned Goal Pursuit (TRGP) to predict young consumers’ SPMB, which includes plastic consumption reduction and proper disposal of plastic waste. Data was collected by surveying 336 respondents from a developing country - Bangladesh. Partial least square-based structural equation modeling (PLS-SEM) was used to analyze data. The result shows a significant impact of active procurement and approval goals on attitude and subjective norms, respectively, that lead to the formation of motivation. Furthermore, it was found that individuals’ motivation significantly impacts their intention, eventually leading to pro-environmental behavior (i.e., SPMB). This research contributes by providing deeper insight into the underlying mechanism of how the active procurement goal (i.e., pro-environmental goals), active approval goal, and motivation interact with other factors to reshape individuals’ SPMB. In addition, this paper provides further evidence on the implication of TRGP in habitual type pro-environmental behavior context. Finally, this paper offers solid suggestions for practitioners to promote circular economy practices at the consumer level to fight against plastic pollution.

Orbitofrontal cortex modulates auditory cortical sensitivity and sound perception in Mongolian gerbils

Sensory perception is dynamic, quickly adapting to sudden shifts in environmental or behavioral context. Although decades of work have established that these dynamics are mediated by rapid fluctuations in sensory cortical activity, we have a limited understanding of the brain regions and pathways that orchestrate these changes. Neurons in the orbitofrontal cortex (OFC) encode contextual information, and recent data suggest that some of these signals are transmitted to sensory cortices. Whether and how these signals shape sensory encoding and perceptual sensitivity remain uncertain. Here, we asked whether the OFC mediates context-dependent changes in auditory cortical sensitivity and sound perception by monitoring and manipulating OFC activity in freely moving Mongolian gerbils of both sexes under two behavioral contexts: passive sound exposure and engagement in an amplitude modulation (AM) detection task. We found that the majority of OFC neurons, including the specific subset that innervates the auditory cortex, were strongly modulated by task engagement. Pharmacological inactivation of the OFC prevented rapid context-dependent changes in auditory cortical firing and significantly impaired behavioral AM detection. Our findings suggest that contextual information from the OFC mediates rapid plasticity in the auditory cortex and facilitates the perception of behaviorally relevant sounds.
