Variation In Behavior Research Articles

A Critical Study of Psychology of Retail Investors

This research critically examines the psychology of retail investors, focusing on the behavioural finance approach to investment decision-making. Behavioral finance challenges the traditional assumption that investors are always rational, proposing instead that psychological, social, and cultural factors influence financial behaviours. The study aims to explore how demographic factors such as gender, age, and investment experience, along with macroeconomic conditions like interest rates and inflation, shape retail investors' decision-making processes. By analysing both quantitative and qualitative data from surveys and questionnaires, the study seeks to uncover patterns in how emotions, cognitive biases, and social networks affect investment choices across different groups. The scope of this research extends to identifying significant variations in investment behaviour based on demographics and cultural influences. Moreover, the study will test hypotheses related to gender differences in the influence of peers and interest rate changes on investment decisions. Through a mixed-methods approach, this research aspires to provide valuable insights for financial institutions and individual investors, enhancing their understanding of the psychological drivers behind market behaviour and investment strategies.

Measuring Docility, Boldness, and Exploration in the Free-Living Yellow Ground Squirrel Spermophilus fulvus Licht. (Sciuridae)

Studying intraspecific variation in animal behavior is one of the key trends in recent biology. Comparative behavioral studies of different species require developing an adequate methodology for every new species. We performed three types of behavioral tests with juveniles of the yellow ground squirrel, a large hibernating rodent. Docility tests with an estimation of the time and intensity of the animal locomotor activity in a bag showed low repeatability and appeared to be inappropriate for this species since most of the pups demonstrated freezing behavior. Boldness tests with an action camera installed near the squirrel’s burrow were more promising, but the juveniles still did not emerge aboveground for a long time after they escaped to their burrows, remained vigilant, and did not explore the new object. Test results indicate that yellow ground squirrels are very shy and cautious, which may be a persistent behavioral trait of this species.

Mobilizing extremism: an examination of the travel patterns of right-wing extremists in the United States

ABSTRACT Extensive criminological research has documented a ‘distance-decay’ effect in criminal activity, with offenders less likely to commit crimes farther from their residences. While recent studies have identified similar patterns in ideologically motivated violence, variation in the travel behaviors of extremists remains underexplored. Using data on right-wing extremists who carried out a violent plot, between 2000 and 2020, alongside information on Capitol insurrectionist arrestees – and drawing on routine activity and rational-choice theories of offender decision-making – this study extends this literature along three dimensions: type, time, and ties. First, we distinguish between different types of offenders, showing that while both violent extremists and insurrectionists exhibit distance-decays, the latter tend to travel farther and exhibit a more irregular decay. Secondly, we identify a meaningful temporal shift in the right-wing extremist landscape, with offenders increasingly traveling longer distances to execute their plots. Finally, we highlight the role of social ties in shaping travel behaviors, where individuals affiliated with extremist groups tend to travel longer distances. These findings contribute to a more nuanced understanding of the spatial behavior of right-wing extremists, the factors influencing their mobility, and the evolving nature of right-wing extremism in the United States.

Spatial and temporal partitioning between eastern gray and fox squirrels in a Central Hardwood forest

Abstract Congeneric fox squirrels (Sciurus niger) and eastern gray squirrels (S. carolinensis) compete for resources within North American temperate forests. Both species exhibit regional variation in morphology and behavior—potentially due to differences in geography, community composition, or ecological pressures between forested regions. While many have studied these species in other forested regions of the United States, recent assessments of partitioning between these species in Central Hardwood forests remain scarce. We investigated spatial and temporal partitioning between squirrel species using photographic captures from camera traps at 2 scales (i.e., camera location and camera cluster) across a 16,058-km2 region of southern Illinois, United States, during January to April 2008 to 2010. We fitted single-season single-species and co-occurrence occupancy models to assess spatial partitioning at both scales and used kernel density analysis to assess temporal partitioning. We recorded 3,044 photographic captures of focal species (n = 918 fox squirrels and 2,126 eastern gray squirrels). Fox Squirrel occupancy was 0.26 ± 0.09 (SE) and 0.50 ± 0.17 at the camera location and camera cluster scales, respectively. Eastern Gray Squirrel occupancy was 0.47 ± 0.07 and 0.84 ± 0.23 at the camera location and camera cluster scales, respectively. Fox Squirrel occupancy increased with further distances to roads and had scale-dependent relationships to forest structure. Eastern Gray Squirrel occupancy increased with more hardwood basal area. Co-occurrence was influenced by distance to road at the camera location scale. We found a moderate level of activity overlap between species (Δ = 0.63, CI = 0.60 to 0.67); however, no evidence of temporal partitioning was observed. Habitat characteristics and spatial scale appear more influential in partitioning eastern gray and fox squirrels in Central Hardwood forests than peak activity.

Database Analysis of Long-Term Settlement Behavior of Pile Foundations in Shanghai Soft Coastal Clays

A database of 195 field records of long-term settlement of high-rise buildings in Shanghai soft coastal clays is presented. The collected field records are divided into two categories based on pile type, i.e., bored pile and precast pile. Based on the settlement recorders collected, the long-term settlement behavior and settlement duration of the pile foundations in soft coastal clays are investigated. The statistical results show that the pile foundation in Shanghai soft coastal clays can be divided into three kinds of site conditions by considering the pile length and variation of long-term deformation behavior. Prediction models based on the power function are proposed to calculate the normalized final settlement for both bored pile and precast pile foundations. Based on the statistical results, the average normalized final settlement (settlement per floor), average settlement ratio (final settlement to the settlement when the superstructure is completed), and average settlement duration in the three site conditions for both bored pile and precast pile foundations are given. Additionally, an exponential settlement prediction model that can accurately forecast the entire settlement and post-construction settlement characteristics of buildings in Shanghai’s soft soil area is proposed. These statistical results can be referred to the preliminary foundation design works, which contribute to the quick evaluation of the possible settlement range, settlement ratio, and settlement duration of the proposed building constructed in the soft coastal clay area in Shanghai.

Investigating the Behavior and Spatiotemporal Variations of Green-line Emission in the Solar Corona

Understanding coronal structure and dynamics can be facilitated by analyzing green-line emission, which enables the investigation of diverse coronal structures such as coronal loops, streamers, coronal holes, and various eruptions in the solar atmosphere. In this study, we investigated the spatiotemporal behaviors of green-line emissions in both low and high latitudes across nine solar cycles, ranging from Solar Cycle 17 to the current Solar Cycle 25, using the modified homogeneous data set. We employed methodologies such as cross correlation, power spectral density, and wavelet transform techniques for this analysis. We found distinct behaviors in green-line energy across various latitudinal distributions in the solar atmosphere. The trends observed at higher latitudes differ from those at lower latitudes. The emission behaviors show a close association with other solar phenomena like solar flares, sunspots, and coronal mass ejections throughout the solar cycles. The observed variations exhibit harmonic periods. The emission activity is significantly higher in the low latitudes, accounting for over 70% of the emissions, while the higher latitudes contribute less than 30%. The emissions exhibit asymmetric behavior between the northern and southern hemispheres, leading to a 44 yr cycle of solar hemispheric dominance shifts. Various factors, such as Alfvén waves, solar magnetic fields, sunspots, differential rotation, and reconnection events, influence the observed differences in behavior between lower and higher latitudes, suggesting the existence of potential underlying phenomena contributing to deviations in properties, intensity, temporal dynamics, and spatiotemporal lifetime.

New Ecological Observations and Occurrence for Asteroidea and Echinoidea in Hong Kong

This paper reports several new occurrences for Asteroidea and Echinoidea in Hong Kong. New records for asteroids include Anseropoda rosacea, Aquilonastra cepheus, Pentaceraster alveolatus, Pentaceraster sibogae, and Culcita novaeguineae. For echinoids, new records include Coelopleurus maculatus, Eucidaris metularia, Prionocidaris baculosa, Echinostrephus molaris, Pseudoboletia indiana, Salmacis bicolor, Stomopneustes variolaris, Toxopneustes pileolus, Clypeaster reticulatus, Metalia spatagus, and Nacospatangus altus. Several novel ecological observations on behavior, diet and morphological variation are also described. These additional occurrences and new observations are attributed to more comprehensive reporting from SCUBA diving as well as the advent of shared resources from social media platforms.

Analyzing the Fast-Food Marketing Strategies Impacting Consumer Buying Behavior

Kentucky Fried Chicken (KFC) has long been a dominant player in the global fast-food industry, known for its distinct fried chicken offerings. This study explores the effect of KFC’s marketing strategies on consumer buying behavior, using the marketing mix framework (4P: Product, Price, Place, Promotion). Primary data were gathered from a survey of 150 consumers in Malaysia via Google Forms, while secondary data included company reports and industry publications. Regression analysis was employed to determine the relationship between the independent variables (product, price, promotion, and place) and consumer buying behavior. Results indicated that product, price, and promotion significantly impact consumer decisions, with the product being the most influential factor (beta = 0.525). Price and promotion also had positive, albeit smaller, effects, while place was statistically insignificant. The R² value of 0.755 suggests that 75.5% of consumer behavior variation can be explained by these factors. These findings underscore the importance of product differentiation and effective promotional strategies in shaping consumer preferences, while the role of physical locations may be diminishing in the fast-food sector due to the rise of delivery services

Effect of Printing Orientation on the Mechanical Properties of Low-Force Stereolithography-Manufactured Durable Resin

This study presents the results of fracture toughness tests conducted on specimens obtained by additive manufacturing techniques, specifically using low-force stereolithography. The samples were manufactured from a transparent 3D printing material for biocompatible applications, the so-called BioMed Durable Resin, which is a Formlabs-patented polymer material that simulates the strength and rigidity of polyethylene. The selected toughness tests in this context were performed following the ASTM D5045-99 guidelines. All tests were conducted under controlled laboratory conditions at 23 °C and 50% relative humidity, ensuring adherence to the standard and the replicability of the experimental results. To investigate the influence of printing plane orientation, specimens were produced at three printing orientation angles (0, 45, and 90 degrees). These angles were selected to provide a comprehensive evaluation of the anisotropy effects in the material. They cover both extreme orientations (0° and 90°) and include an intermediate value (45°), allowing us to assess variations in mechanical behavior across a representative range of printing orientations, consistent with prior research in the field. The experimental tests yielded data on the crack resistance and energy release rate for each angle of orientation. There are various implications of the findings, beyond materials engineering, for applications in biomedicine. Indeed, this same approach opens the door to new research methods for manufacturing certified biocompatible materials from such durable resins. Finally, complementary issues such as related medical applications have been slightly addressed for future work, since biomedicine innovation clusters can contribute to accelerating growth in this crucial field for productive sector activity and the local business environment.

Psychometric Properties and Measurement Equivalence of the Workplace Incivility Scale Across Cultures: Insights from Daily Diary Study.

Despite extensive research on workplace incivility, little attention has been given to its validation in culturally distinct contexts such as China and Pakistan. This study aims to bridge this gap by investigating the psychometric properties of the workplace incivility scale within these cultural frameworks. Additionally, it seeks to explore the cross-cultural measurement equivalence of the workplace incivility scale between these two diverse settings using a daily diary study design. The sample consisted of employees from service-providing organizations in China and Pakistan. Data was collected through snowball sampling, resulting in responses from 100 Chinese and 115 Pakistani employees over 10 consecutive workdays. Analysis of the daily responses, encompassing 748 from Chinese and 833 from Pakistani workers, indicated successful validation of the scale within both populations. This demonstrates the transferability of the concept of incivility to these cultural contexts. An integral aspect of this study is the consideration of potential cultural variations in workplace uncivil behavior. The validation and measurement equivalence of the scale for the core construct serves as essential infrastructure supporting such research endeavors.

Comparing MJO Intensity over the Tropical Western Pacific during Mega and Equatorial La Niña Winters

Abstract This study investigated variations in the Madden–Julian oscillation (MJO) behavior between two types of La Niña winters: mega and equatorial La Niñas. Results of this work show that in contrast to mega conditions, accompanied by more abundant intraseasonal column-integrated moisture anomalies over the planetary boundary layer, intensities of intraseasonal outgoing longwave radiation anomalies are stronger over the tropical western Pacific (WP) at MJO phases 5–6 under equatorial conditions. The occurrence of the moisture anomaly change averaged over the tropical WP is supported by a distinct moisture tendency difference. Moisture budget and multiscale interaction diagnoses underscore the pivotal effect of an area-averaged vertical gradient change in low-frequency background moisture in driving such tendency change. Considering notable MJO convection variations, the teleconnections associated with MJO phases 5–6 over East Asia (EA) were also explored, including warmer surface air temperature anomalies and stronger positive geopotential height anomalies at 200 hPa on the intraseasonal time scale under equatorial conditions. Results from a linear baroclinic model demonstrate that such teleconnection changes could be effectively explained by the linear response to the MJO’s diabatic heating anomaly. Roles of mean state and MJO itself variations in the linear response change are also discussed. These findings provide novel insights into MJO activity and offer potential improvements for subseasonal forecasting in EA. Significance Statement The relationship between El Niño–Southern Oscillation (ENSO) and MJO has been extensively explored recently. However, variations in the MJO behavior and its climate effects under mega and equatorial La Niña winters have not been thoroughly investigated. In this work, we utilized reanalysis datasets and an idealized linear baroclinic model to address these questions. We observed more robust and abundant intraseasonal convection activity and planetary boundary layer–integrated moisture anomaly averaged over the tropical WP at MJO phases 5–6 under equatorial conditions than mega conditions, which is closely linked with the vertical gradient change in low-frequency background moisture. Additionally, MJO-related teleconnections also exhibit some changes. This work may provide a new perspective on understanding the relationship between the MJO and ENSO and offer potential improvements for the subseasonal forecast.

Unmasking the Pandemic's Dark Side: Exploring the Roles of Stress, Emotions, and Alcohol Use in Violent Behavior Across Six Countries.

We use international survey data recently collected among adults in six countries (Ukraine, Guatemala, Pakistan, the Netherlands, Denmark, and the United States) to examine the global variations in interpersonal violent behavior during the COVID-19 pandemic. We find that pandemic-related stress is significantly associated with violent behavior in most countries. Depression emerges as a significant predictor of violence across all countries and as a mediator between pandemic stress and violent behavior in multipls contexts. On the other hand, negative affect and alcohol use predict violent behavior only in non-Western contexts. We provide policy implications focused on prevention and reduction of violence cross-nationally during public health crises.

Physiological and behavioral variation by urbanization and climate in an urban-tolerant toad

The distribution of a species is best understood by examining the organism-environment interaction. Climate and anthropogenic habitat degradation, including urbanization, are salient features of the environment that can limit species distributions, especially for ectotherms. Comparative studies of the capacity of individuals to cope with rapid environmental change can help us understand the future success or failure of local populations or even the species. Studies of the glucocorticoid stress response are commonly used to understand how species cope with environmental stressors. Glucocorticoids modulate many aspects of physiological homeostasis including changes in energetic allocation and behavior. In a time of global amphibian decline the Gulf Coast Toad (Incilius nebulifer) is increasing its distribution and abundance. To understand how this species deals with thermal and urban stressors, we studied glucocorticoid regulation, hop performance, and lipid storage in I. nebulifer juveniles across nine populations that differed in average annual temperature and level of imperviousness (as an indication of urbanization). We measured corticosterone release rates at baseline, during agitation stress, and during recovery; then measured locomotor performance and whole-body lipids. We tested if I. nebulifer in hotter temperatures and more urbanized habitats exhibits elevated baseline corticosterone levels and either a reduced corticosterone stress response (“stress resistance” hypothesis) or quick post-stress recovery by negative feedback (“on again, off again” hypothesis). We also tested whether they exhibit reduced fat stores and decreased locomotor performance as costs of dealing with thermal and urban stressors. We found that I. nebulifer showed elevated baseline and agitation (stressed-induced) corticosterone release rates, and higher lipid storage with increasing urbanization. Climate had quadratic effects on these traits, such that populations living at the lowest and highest temperatures had the lowest corticosterone release rates and lipid stores, and the highest hop performance was observed in the least urbanized site at the warmest climate. Additionally, the rate of glucocorticoid recovery after agitation (negative feedback) decreased with increasing temperature and increased with increasing urbanization. These results indicate that I. nebulifer follows the “on again, off again” hypothesis in an adaptive pattern, which may help them cope with environmental change in terms of urbanization and climatic differences.

Study of the varietal behavior of 07 durum wheat varieties (Triticum durum Desf.) in the Oued Righ Valley (ITDAS Station)

Cereal production in the Oued Righ Valley is limited by several factors, including high temperatures and the salinity of irrigation water. These constraints cause significant variations in crop behavior and yield. This study aims to evaluate the performance of seven durum wheat varieties at the El Arfiane demonstration and seed production farm (ITDAS) in the Oued Righ Valley in the south East of Algeria. The evaluation focuses on morphological parameters and yield components To identify the variety or varieties that demonstrate favorable performance and yield, thus encouraging local farmers to cultivate them. The results of this study indicate significant differences in morphological parameters such as plant height, spike length, number of spikes per square meter, and number of grains per spike. However, other measured parameters, such as the number of tillers per plant, thousand-grain weight TGW, grain yield, and harvest index, The methodology employed in this study follows a completely randomized block design with three replications. The experimental design includes a set of experimental units arranged in blocks, with treatments randomly assigned within each block, hence the term "completely randomized block." Each treatment appears only once in each block. The blocks are typically placed contiguously to facilitate observations and task execution. This design is widely used in agronomy as it simplifies task execution and the comparison of treatments. Despite an acceptable thousand-grain weight this year, ranging from 37.06g for variety T4 to 27.6g for variety T1, the yields were low. The highest biological yield was 33.11 quintals per hectare for variety T5, while the lowest yield was 11.39 (T2) quintals per hectare. Several factors, including pigeon attacks and harvest losses, contributed to the reduced real yield.

Association between snack intake behaviors of children and neighboring women: A population-based cross-sectional analysis with spatial regionalization

BackgroundAccumulated evidence indicates that neighborhood environments affect children's health behaviors. However, measuring neighborhood environments remains challenging because there exist strengths and weaknesses both in objective and perceived environment measures. Drawing on a recent conceptual model of how environment, perception, and behavior interact, we hypothesized that neighbors' behavioral similarities indicate the combined influence of physical and social environmental opportunities on specific behaviors. We then examined how these similarities (i.e. the behavioral tendencies of children's adult neighbors) relate to children's obesogenic dietary behaviors. MethodsWe used data for 2275 women and 821 elementary schoolchildren from a 2012–2013 population-based survey in greater Tokyo, Japan. Snack intake was defined as the total consumption of various types of snacks, estimated using a validated self-administered diet history questionnaire. Spatial regionalization, a type of spatial clustering, was used to empirically identify segments that could effectively differentiate regional variation in women's snack intake behaviors. We conducted multiple regression analysis to assess the cross-sectional association between children's snack intake and the mean snack intake of neighborhood women, adjusting for mother's intake. ResultsA 1-g increase in the mean snack intake of neighborhood women was associated with a 0.23-g (95% confidence interval: 0.00–0.45) increase in children's intake, while a 1-g increase in mother's intake was associated with a 0.34-g (95% confidence interval: 0.26–0.41) increase in children's intake. DiscussionThe results suggest that the out-of-home physical and social neighborhood environments may have non-ignorable associations with children's dietary behaviors by offering behavioral opportunities in addition to maternal influence.

Large deformation of variable thickness woven composite preforms considering interlayer difference. Application: Forming simulation of a blade preform

The main objective of this work was to investigate the interlayer difference of 3D orthogonal woven fabrics (3DOWFs) during deformation. Tensile, shear, and compression tests were performed on two types of 3DOWFs with different layer numbers. To determine the variations in the deformation behavior within the fabric, a layer decomposition method was developed. This process involved the decomposition of the fabric into two layers, the inner layer and the outer layer, depending on the difference in structural features of the yarn. Then the deformation characteristics of the inner layer and outer layer were derived based on their series or parallel relationship in the load path. The results indicate that there are noticeable variations in the deformation characteristics among the layers of 3DOWF, which are associated with the interwoven structure of the yarns. In particular, in compression deformation, the difference in yarn structure causes the initial stage (Compressive strain <0.2) of fabric compression deformation to be mostly attributed to the compression of the outer layer. Subsequently, the deformations of the inner layer and outer layer gradually tend to balance. Based on a simple anisotropic hyperelasticity model, the interlayer differences were considered in the blade preform simulation. The simulation result shows a good agreement with the preforming results. The results show that the interlayer difference has a significant impact on the deformation of the blade preform, particularly in the posterior edge region, which is not strongly compressed.

Age, period, and cohort effects of Clonorchis sinensis infection prevalence in the Republic of Korea: Insights and projections.

With decades of containment efforts, the prevalence of C. sinensis infection in Korea has shown a declining trend. However, well-tailored intervention assessments remain challenging, particularly when considering the potential impacts of cohort variations in raw freshwater fish consumption behavior, a major transmission route to humans, on this observed decline. We applied an age-period-cohort modeling approach to nationally representative C. sinensis infection prevalence data from 1981-2012 in Korea to assess age, period, and cohort effects on its secular trend and to project the age-stratified prevalence up to 2023. Our analysis suggests that both cohort and period effects have substantially contributed to the declining prevalence of C. sinensis infection in Korea. Age-stratified projections up to 2023 suggest a decline in prevalence across all age groups, while those aged over 40 are anticipated to maintain prevalences above the elimination threshold of 1%. Our study highlights the importance of incorporating cohort effects into intervention assessments aimed at controlling C. sinensis infection. The effectiveness of interventions remains evident in Korea despite adjusting for the cohort effect. This approach, applicable to other endemic countries, would provide valuable insights for intervention assessments and inform future public health planning to eliminate C. sinensis infection.

Carrier-envelope phase effects on the reflectance of diamond films irradiated by ultrashort single-cycle light pulses: A comparison study in attosecond and femtosecond regimes

Diamond films irradiated with few-cycle laser pulses are emerging as a all-optical information processing device with high-speed and low-power-consumption. The possibility to steer, control or switch such few-cycle laser pulses with diamond films is expected to pave the way towards ultrafast all-optical switching. Here, we show theoretically the effect of the carrier-envelope phase (CEP) of the ultrashort single-cycle light pulses on the reflectance of diamond films within the framework of multi-scale theory. We observe clear variations in the reflectance behavior of femtosecond pulses and attosecond pulses. Our most important finding is that the reflectivity difference of attosecond pulses with different waveforms and the same spectrum on diamond films exhibits a perfect quadratic relationship with the CEP. This observation suggests that the nonlinearity of attosecond pulses is different from that of femtosecond pulses. Analysis of these results allows us to gain new insights in the interaction between attosecond light pulses and matter. This opens fascinating avenues for all-optical information processing over ultrashort lengths and timescales.

Effects of Anthropic Structures on Morphodynamic Beach Evolution along the Gulf of Roses (Northwestern Mediterranean, Spain)

This study conducts a morphodynamic analysis of beaches located in the northern sector of the Gulf of Roses (NW Mediterranean, Spain). The primary objective is to investigate mid-short (2004–2020) term spatial and temporal variations in shoreline position and sedimentological behaviour. The study area covers the northern part of the gulf, spanning 9.86 km, and includes both natural beaches and heavily anthropized ones. The following GIS methodologies were employed to study the variations in the coastline: QGIS for areas and DSAS-ArcGIS for transects, quantifying coastal changes from 2004 to 2020. Sediment samples were collected from both the dry beach and swash areas for each profile. The results reveal minor discrepancies in shoreline evolution data, depending on the method used (transects or areas). Profile-based analysis shows an average annual rate of −0.11 m·y−1 (ranging between 0.53 and −0.55 m·y−1), while areal-based results (2004–2020) indicate a total loss of −20,810 m2 (−1300 m2·y−1). Sediment grain size decreases northward (from 745 to 264 µm in the swash zone). Changes in shoreline position and grain size illustrate the impact of various anthropogenic structures on morphodynamic behaviour. These structures preferentially deposit specific grain sizes and impede sediment transport, which will cause an advance in the position of the shoreline and sediment grain sizes upstream and a reverse process downstream. This study underscores the influence of coastal anthropization on beach morphology and sedimentology, generating distinct morphodynamic behaviour.

PVC/CNT Electrospun Composites: Morphology and Thermal and Impedance Behavior.

Due to their mechanical robustness and chemical resistance, composite electrospun membranes based on polyvinyl chloride (PVC) are suitable for sensor applications. Aiming to improve the electrical characteristics of these membranes, this work investigated the effects of the addition of carbon nanotubes (CNTs) to PVC electrospun membranes, in terms of morphology and thermal and impedance behavior. Transmission electron microscopy images evidenced that most of the nanotubes were encapsulated within the fibers and oriented along them, while field-emission scanning electron micrographs revealed that the membranes consisted of uniform fibers with an average diameter of 339 ± 31 nm, regardless of the addition of the carbon nanotubes. With respect to the neat resin, the addition of nanotubes caused a significant lowering of the glass transition temperature (up to 20 °C) and a marked change in the second degradation step of PVC. Nyquist plots from electrical impedance spectra showed a charge transfer resistance (RCT) of 38 and 40 MΩ for neat PVC and PVC/CNT 3 wt.% membranes, respectively, indicating that, in the dry state, the encapsulation of CNTs in the fibers and the high porosity of the membranes prevented the formation of a percolation network, increasing the electrical resistance. In the wet state, however, there was a greater change in the impedance behavior, decreasing the resistance RCT to 4.5 and 1.1 MΩ, for neat PVC and PVC/CNT 3 wt.% membranes, respectively. The results of this study, showing a significant variation in impedance behavior between dry and wet membranes, are relevant for the development of various types of sensors based on PVC composites.
