Lifestyle behaviors and mental health outcomes in sexual and gender minority graduate students

Objective There are well-documented health disparities among sexual and/or gender minority (LGBTQ+) individuals generally, but there is limited research investigating the disparities in health-related lifestyle factors and mental health among LGBTQ+ graduate students, which is a group that may be especially vulnerable. Participants This project was a secondary analysis of data from the American College Health Association’s National College Health Assessment’s (NCHA) Fall 2019 wave, which included 7,766 graduate students. Methods Students self-reported engagement in health-related lifestyle factors and psychological distress. Welch’s independent samples t-tests were used to compare differences in psychological distress and lifestyle behaviors and multiple linear regression models were used to test lifestyle factors as predictors of LGBTQ+ psychological distress. Results LGBTQ+ graduate students reported worse lifestyle profiles compared to their peers and greater psychological distress. Sleep quality had the strongest association with psychological distress among LGBTQ+ graduate students. Conclusions These findings have important implications for policies and interventions to improve health and decrease suffering in LGBTQ+ graduate students.

Absent, but not glucocorticoid-modulated, corticotropin-releasing hormone (Crh) regulates anxiety-like behaviors in mice.

The hypothalamic-pituitary-adrenal (HPA) axis is a well characterized endocrine response system. Hypothalamic Crh in the paraventricular nucleus of the hypothalamus (PVH) initiates HPA axis signaling to cause the release of cortisol (or corticosterone in rodents) from the adrenal gland. PVH-specific deletion of Crh reduces anxiety-like behaviors in mice. Here we report that manipulation of PVH Crh expression in primary adrenal insufficiency or by dexamethasone (DEX) treatment do not alter mouse anxiety behaviors. In Experiment 1, we compared wildtype (WT) mice to those with primary adrenal insufficiency ( Mrap KO) or global deletion of Crh ( Crh KO). We analyzed behaviors using open field (OF) and elevated plus maze (EPM), PVH Crh mRNA expression by spatial transcriptomics, and plasma ACTH and corticosterone after a 15-minute restraint test with ELISAs. EPM analysis showed Crh KO mice were less anxious than WT and Mrap KO mice, and Mrap KO mice had no distinguishing behavioral phenotype. In Experiment 2, we evaluated HPA axis habituation to chronically elevated Crh expression by comparing mice treated with 5-8 weeks of DEX with those similarly treated followed by DEX withdrawal for 1 week. All mice regardless of genotype and treatment showed no significant behavioral differences. Our findings suggest that reduced anxiety associated with low Crh expression requires extreme deficiency, perhaps outside of those PVH Crh neurons negatively regulated by glucocorticoids. If these findings extend to humans, they suggest that increases in Crh expression with primary adrenal insufficiency, or decreases with exogenous glucocorticoid therapy, may not alter anxiety behaviors via modulation of Crh expression.

What explains the sex differences in family leisure activities of children? A genetically sensitive analysis with twin data

Objective: This paper examines to what extent genetic and environmental influences contribute to differences in family leisure activities of girls and boys. Background: While family leisure activities have been described as relevant for child development, it remains unclear what accounts for differences in the leisure behavior of girls and boys. While research emphasized the importance of the environment, e.g., in relation to gender role socialization, other studies pointed to biological and, thus, genetic differences as explanatory factors. Method: The analysis is based on 954 female and 1036 male twins aged 10-12 years who are part of the first wave of the German Twin Family Panel Study. Our analysis examines five family leisure activities using variance decompositions and gene-environment interaction models. Results: Overall, there were only minor differences between girls and boys in the contributions of genes and environments to family leisure activities. Only for singing and making music did influences from the environment common to both twins contribute more strongly to the performance of these activities in the girls than in the boys. Conclusion: There is no evidence that genetic differences lead to differences in family leisure behavior between girls and boys in the activities considered here. Existing differences are more likely to be due to environmental influences.

A unified confinement-based direct design approach for novel double-skin composite columns

Concrete-filled stiffened steel tubular short columns, with cold-formed stiffened steel tubes for the outer section, have been widely used in Asia in large commercial facilities and warehouses. This paper focuses on the response of concrete-filled double-skin stiffened steel tubular (CFDSST) short columns and concrete-filled dual stiffened steel tubular (CFDST) short columns, with either square or circular inner tubes. A detailed database of existing information is assembled and presented, as well as a thorough analysis of existing design expressions. Additional examination of the concrete confinement has been undertaken which highlight the differences in behaviour between CFDSST and CFDST cross-sections. The major aim in this work is to provide a unified design approach, which accounts for concrete confinement and accounts for the material and geometric properties of the section, and offers improved accuracy over the existing approaches given in the European, American, British and Chinese design codes. The newly proposed unified confinement-based direct design approach for axially-loaded CFDSST and CFDST short columns is discussed, including the consideration given to the lateral confining pressure provided by the steel tubes. This method is shown to provide more accurate depictions of the load resistances of CFDSST and CFDST short columns relative to the international specifications, with lower scatter and greater range of applicability. It has also been shown that the CFDSST sections with a stiffened outer steel tube provides greater confinement and additional strength compared with equivalent unstiffened circular tubes of high relative tube slenderness. Given the easier fabrication and installation of beam-to-square column joints compared with circular columns, this is likely to extend their range of application in the future.

Temporal and spatial analysis of event-related potentials in response to color saliency differences among various color vision types.

Human color vision exhibits significant diversity that cannot be fully explained by categorical classifications. Understanding how individuals with different color vision phenotypes perceive, recognize, and react to the same physical stimuli provides valuable insights into sensory characteristics. This study aimed to identify behavioral and neural differences between different color visions, primarily classified as typical trichromats and anomalous trichromats, in response to two chromatic stimuli, blue-green and red, during an attention-demanding oddball task. We analyzed the P3 component of event-related potentials (ERPs), associated with attention, and conducted a broad spatiotemporal exploration of neural differences. Behavioral responses were also analyzed to complement neural data. Participants included typical trichromats (n = 13) and anomalous trichromats (n = 5), and the chromatic stimuli were presented in an oddball paradigm. Typical trichromats exhibited faster potentiation from the occipital to parietal regions in response to the more salient red stimulus, particularly in the area overlapping with the P3 component. In contrast, anomalous trichromats revealed faster potentiation to the expected more salient blue-green stimulus in the occipital to parietal regions, with no other significant neural differences between stimuli. Comparisons between the color vision types showed no significant overall neural differences. The large variability in red-green sensitivity among anomalous trichromats, along with neural variability not fully explained by this sensitivity, likely contributed to the absence of clear neural distinctions based on color saliency. While reaction times were influenced by red-green sensitivity, neural signals showed ambiguity regarding saliency differences. These findings suggest that factors beyond red-green sensitivity influenced neural activity related to color perception and cognition in minority color vision phenotypes. Further research with larger sample sizes is needed to more comprehensively explore these neural dynamics and their broader implications.

Sex differences in behavior and glutamic acid decarboxylase in Long Evans rats after prolonged social isolation beginning in adolescence.

Social isolation can have long-term effects on brain development and behavior and increases the risk of developing clinical conditions, including anxiety disorders. One modulator of the stress response is gamma-aminobutyric acid, an inhibitory neurotransmitter synthesized by glutamic acid decarboxylase (GAD). This study examined sex differences in behavior and GAD expression following prolonged social isolation beginning in adolescence in Long Evans rats. Males and females were equally divided into group-housed (GH) and socially isolated conditions on Postnatal Day 28 (n = 8 per group). Beginning 5 weeks later, tests were conducted for anxietylike behaviors (open-field test and elevated plus maze), social interactions (sociability test), and spatial memory (novel object location). Sex differences in behavior were observed, with GH females showing fewer anxietylike behaviors in the open-field test and elevated plus maze and spending more time with objects (sociability task) compared to GH males. Isolation had no effect on males but increased anxiety and reduced neophilic measures in females, removing sex differences. On the sociability task, all groups spent more time with novel rats compared to objects, suggesting social interest was retained after isolation. In the hippocampus, isolation reduced GAD in both sexes, and sex differences were seen (F > M). However, no group differences in behavior were observed in the hippocampal-dependent novel object location task. Our findings suggest that prolonged social isolation beginning in adolescence is anxiogenic for female Long Evans rats. Furthermore, sex and housing impact hippocampal GABA-ergic activity, which may have important implications in the treatment of anxiety disorders.

Empowered or informed? Seeking to mitigate gender differences in first-offer assertiveness through pre-negotiation interventions

Gender differences in negotiation behavior—for instance, men’s vs. women’s likelihood to make (assertive) first offers—contribute to the globally prevalent gender pay gap (GPG). In an attempt to mitigate the social and economic consequences of this gender disparity, we first empirically validated two pre-negotiation message interventions in a pilot study (N = 203). In the main experimental intervention study (N = 585), male versus female participants randomly received this (1) informative message about the GPG, or (2) gender-specific empowering message, or (3) no message in the control condition. In a subsequent negotiation task on the starting salary for a new job, we assessed participants’ (a) likelihood-to-initiate a first offer and (b) first-offer assertiveness. Results showed a remarkably robust behavioral gender disparity: across all conditions, men were more likely to make the first offer (d = 0.178) and made them more assertively (d = 0.339). Importantly, compared to the control condition, the informative (dinform = 0.304) and the empowering (dempower = 0.255) pre-negotiation interventions increased women’s first-offer assertiveness. Similar intervention benefits emerged for men (dinform = 0.259; dempower = 0.284), however, yielding an overall remarkably robust gender difference. To explore the underlying reasons for this gender disparity, we tested four competing psychological mechanisms (i.e., self-esteem, positive and negative affect, GPG awareness, and self-efficacy). Our results highlight the impact that even short, minimal interventions can have on gender differences in negotiation behavior and illustrate which psychological mechanisms explain the emergence of gender disparity in the first place.

Age- and Sex-Specific Differences in Lyme Disease Health-Related Behaviors, Ontario, Canada, 2015-2022.

We investigated differences in risk factors and preventive behaviors by age and sex among persons with reported Lyme disease in Ontario, Canada, during 2015-2022. Incidence rates peaked among children 5-9 and adults 50-79 years of age. Median age was higher for female than male case-patients (54 vs. 51 years). Male case-patients reported more activity in wooded and tall grass areas than did female case-patients; fewer male case-patients reported sharing living space with outdoor-exposed companion animals. As age increased, more case-patients reported activity in blacklegged tick habitats, exposure to ticks, and wearing adequate clothing, but fewer reported sharing living space with outdoor-exposed companion animals. Adoption of preventive behaviors was relatively low and did not differ by sex. Male case-patients, children 5-9 years of age and their parents or caregivers, and adults >59 years of age represent populations that would benefit from tailored public health messaging on Lyme disease prevention.

Sex differences in exploratory behavior of rats successfully performing the object-in-place recognition memory test

Male and female rodents display unique search strategies when exploring new and familiar environments. Sex differences are well-documented in the literature and may be observed in tasks that rely on spontaneous exploration (e.g., recognition memory tests). Therefore, we assessed patterns of male and female rat behavior in the object-in-place (OiP) test, a common recognition memory paradigm involving object-location associations. Twelve male and 12 female adult Long Evans rats were tested four times in the 1-h OiP test and exploratory behaviors were compared during habituation, sample, and test phases. Results revealed that females moved faster and farther than males, showed increased immobility frequency and reduced immobility duration, reduced outer zone mobility duration, and increased inner zone entrances, compared to males during habituations. During sample phases, female rats moved faster than males, displayed reduced immobility frequency in the inner zone, and demonstrated consistent distance travelled across repeated sessions; conversely, male rats moved less in later sessions and exhibited increased mobility frequency in the outer zone. Analyses comparing test phase behavior revealed females continued to move faster than males; however, no other sex differences were observed. These findings are consistent with previous literature highlighting unique sex differences in explorative behaviors during recognition testing. Sex differences in locomotion and mobility state behaviors may be more indicative of individual motivation and search strategy between the sexes and less indicative of recognition memory.

D-MHGCN: An End-to-End Individual Behavioral Prediction Model Using Dual Multi-Hop Graph Convolutional Network.

Predicting individual behavior is a crucial area of research in neuroscience. Graph Neural Networks (GNNs), as powerful tools for extracting graph-structured features, are increasingly being utilized in various functional connectivity (FC) based behavioral prediction tasks. However, current predictive models primarily focus on enhancing GNNs' ability to extract features from FC networks while neglecting the importance of upstream individual network construction quality. This oversight results in constructed functional networks that fail to adequately represent individual behavioral capacity, thereby affecting the subsequent prediction accuracy. To address this issue, we proposed a new GNN-based behavioral prediction framework, named Dual Multi-Hop Graph Convolutional Network (D-MHGCN). Through the joint training of two GCNs, this framework integrates individual functional network construction and behavioral prediction into a unified optimization model. It allows the model to dynamically adjust the individual functional cortical parcellation according to the downstream tasks, thus creating task-aware, individual-specific FCNs that largely enhance its ability to predict behavior scores. Additionally, we employed multi-hop graph convolution layers instead of traditional single-hop methods in GCN to capture complex hierarchical connectivity patterns in brain networks. Our experimental evaluations, conducted on the large, public Human Connectome Project dataset, demonstrate that our proposed method outperforms existing methods in various behavioral prediction tasks. Moreover, it produces more functionally homogeneous cortical parcellation, showcasing its practical utility and effectiveness. Our work not only enhances the accuracy of individual behavioral prediction but also provides deeper insights into the neural mechanisms underlying individual differences in behavior.

A simplified method for calculating air conditioning load of multi-family housing community considering the spatiotemporal distribution of occupants

Occupant behavior is considered a vital factor influencing housing energy consumption by adjusting the indoor thermal environment and the use of service system. Multi-family housing is popular in the hot summer and cold winter (HSCW) zone of China, where residents typically adopt a “partial time, partial space” approach to environmental control. Therefore, the behavioral differences among families pose challenges for predicting hourly energy consumption at community scale. Taking Changsha, a typical city in the HSCW zone, as an example, this study investigates and summarizes the spatiotemporal distribution characteristics of multi-family occupants, analyzing their impact on air conditioning (AC) load under ideal environmental control conditions (i.e., AC is on where is occupied). Hourly AC load modified equations and multi-family occupancy modified coefficients are introduced to construct a method for estimating hourly AC load of residential communities that comprehensively considers the spatiotemporal distribution of multi-family occupants. The results show that the proposed method achieves fitting degrees of 87%-92.4% for predicting heating load and 77.9%-84.9% for predicting cooling load. This method not only dramatically reduces the workload and time required for physical modeling of residential communities, but also enables fast and refined simulation of the hourly AC load.

Sex-Based Differences in Multilocus Heterozygosity in Wild Boar from Spain

Wild boar (Sus scrofa) populations are increasing worldwide, leading to health, economic and conservation issues. Assessing genetic structure and diversity can aid in the effective monitoring and management of wild boar populations. Processes related to sexual selection and behavioral differences between sexes support the importance of considering sex in measuring genetic diversity. In this study, we investigated the genetic diversity of wild boar in southwestern Spain by comparing multilocus heterozygosity (MLH) in males and females. We collected tissue samples from 142 culled individuals and 146 fetuses during routine hunting activities and used 16 microsatellite markers to quantify MLH. Paternity analyses were conducted to infer the genotypes of reproductive males. Our results indicated that the sampled individuals constituted a unique polygynandrous population without clear genetic structure. We found that males tended to exhibit lower MLH than females, with reproductive males showing significantly lower MLH than females. We discuss the selection and demographic processes that might explain our results. We highlight the importance of sex-balanced culling for population control, as well as the use of sex-balanced samples for monitoring genetic diversities.

Program Reach and Motivational Correlates of Exercise Behavior among Program Participants with Visual Impairment

ABSTRACT Introduction Adults with visual impairments (VI) experience unique barriers to exercise. Targeted exercise programming can eliminate barriers, but little is known about who engages in such programs. This cross-sectional study a) describes program reach and motivational correlates of exercise behavior among members of specialized exercise programs offered to adults with VI; b) examines demographic, psychological, and behavioral differences according to VI severity; and c) assesses the interrelationships between motivational characteristics and exercise behavior. Methods Data for program participants were provided to researchers by the partnered organization with participant consent. A total of 118 participants also completed a post-program survey on motivational characteristics and exercise behavior. Reach was assessed with descriptive statistics. T-tests and chi-squared tests were used to analyze respondent representativeness compared to the population of program participants (demographically) and normative values (motivationally). Analysis of variance examined differences according to VI severity. Pearson’s correlations and multiple regression assessed strength and independence of relationships between motivational variables and exercise. Results Programs attracted mostly equivalent groups of individuals across gender and varying severity of VI. Survey respondents were representative of program participants but were significantly more approach motivated and less avoidance motivated than published norms, and mostly exhibited autonomous forms of motivational regulation for exercise. Differences according to VI severity were not significant. Relationships between approach motivation and exercise were no longer significant when modeled with motivational regulation for exercise. Identified regulation was the lone significant predictor of exercise in the multivariate model. Conclusion This study presents a novel understanding of the demographic and motivational reach of specialized programming for adults with VI, as well as the motivational correlates of exercise behavior among existing program participants. Motivational characteristics were related to exercise behavior in a way that was consistent with theory, such that contextualized motivational regulation demonstrated stronger associations with exercise behavior than motivational dispositions.

Sensor-Based and Visual Behavioral Profiling of Dry Holstein Cows Presenting Distinct Median Core Body Temperatures

The consequences of heat stress during the dry period can extend into the postpartum period, affecting health and productivity in the subsequent lactation. We hypothesized that cows with distinct core body temperatures (CBTs) would exhibit disparate behaviors associated with different degrees of heat generation or dissipation. The primary objective was to investigate behavioral differences of dry Holstein cows (n = 50) classified as high-temperature (HT) or low-temperature (LT), based on median CBT during the summer months using visual observations and accelerometer technology. A secondary objective was to investigate the transcriptome of white blood cells (WBCs) collected from a subgroup of HT and LT cows (n = 5; per group). Minor behavior differences were observed during the visual observations (performed for a total of 16h/cow). Based on automated monitoring system (AMS) data, collected 24/7 over a period of 42 days per cow, HT cows displayed higher periods of high activity and lower periods of inactivity prepartum and diminished rumination time postpartum than LT cows. There were 16 differently expressed genes (DEGs) in WBCs of HT compared to LT cows. Several of the identified DEGs have been previously associated with heat stress. The observed trends in the AMS data indicate that CBT and patterns of activity prepartum may serve as valuable predictors for identifying dairy cows with distinct tolerance to heat stress.

Developmental Social Experience Changes Behavior in a Threatening Environment in Corydoras Catfish

ABSTRACTCoordinated responses to threats are important for predator evasion in many species. This study examines the effect of developmental social experience on antipredator behavior and group cohesion in a highly gregarious catfish that communicates via tactile interaction, Corydoras aeneus. We reared fish either in a mixed‐age group of age‐matched peers and adult C. aeneus (mixed‐age condition, or MAC), or with age‐matched peers only (same‐age condition, or SAC). A startle test was conducted with small groups of subadults from either social rearing condition. Prior to any startle events, SAC subadults had increased tactile communication compared to MAC subadults, but SAC individuals were overall less active. SAC fish exhibited a stronger antipredator response to startles, and were more likely to freeze or take refuge in cover in response to a startle than MAC fish. MAC fish tended to respond to startle events by maintaining or decreasing their cohesion, whereas SAC fish tended to maintain or increase their cohesion. These behavioral differences are attributed to MAC fish developing with group protection as a result of shoaling with adults, resulting in reduced antipredator responses when reared with adults. This study underscores how social context during development can be critical in shaping how individuals perceive and respond to potential threats in their environment.

Comparative study of Ni nanoparticles synthetized using electroless Ni plating waste and an analytical Ni reagent. Characterization and possible application in magnetic fluids

Wastewater from the electroless industry represents a potential danger to the environment and health, mainly due to its heavy metal content. In this study, nickel nanoparticles were synthesized through chemical reduction precipitation by using an electroless nickel plating waste and hydrazine sulfate as reducing agent. The aim of the present work is twofold. First we want to extract the metal from the aqueous medium, minimizing its content to levels allowed by environmental regulations. Second, we aim to valorize the residue by recovering the precipitated nickel to be applied as a solid phase in a magnetic fluid (MF). It is found that the present synthesis method using N2H4 as reducing agent, allowed us to minimize the Ni concentration in the aqueous waste in 97.49 %. The properties of the recovered Ni precipitate is compared with the Ni nanoparticles (NPs) obtained from a solution prepared with analytical grade nickel sulfate. The synthesized materials from both the waste (Ni-R) and analytical reagent (Ni-A) were characterized by comparing their chemical, physical, and morphological properties. In both cases, the Ni-R and Ni-A precipitates, spherical Ni NPs of 8–10 nm crystallite sizes are obtained, agglomerated in a bimodal size distribution centered at 174.6 and 383.4 nm, and a monomodal size distribution centered at 63.6 nm, respectively. Both Ni precipitated samples are ferromagnetic, but the Ni-R sample has a higher magnetic saturation of 40 emu/g compared to 8 emu/g of the Ni-A sample. The difference in the rheological behavior of both precipitates could be attributed to the presence of surface oxidation having a relatively less contribution in the case of the Ni-R particles due to the higher average size of the particles. The Fe content, probably coming from the nickel-plated parts in spent baths, is slightly higher in the Ni-R sample. Thus, the present work shows that it is possible to valorize an industrial Ni-based residue, by obtaining Ni precipitates that in magnetic fluids give even better results than those expected under more rigorous experimental conditions, i.e., in cases where the quality of the chemical precursors is usually a determining factor.

Polyetherimide copolymer film with room-temperature self-healing properties and high breakdown field strength

With the waste of resources caused by human activities, it has gradually become an increasingly prominent social problem. The development of self-healing polymers in the field of insulation has attracted widespread attention. Develop polymer matrices with efficient healing efficiency and sound insulation properties to achieve green and sustainable resource conservation. In addition, improving the dielectric properties of intrinsic self-healing matrices has been a hot topic. In this work, we developed a new PEI matrix-modified self-healing polymer substrate that provides a breakdown field strength of 240 kV/mm and self-healing properties at room temperature, this has significantly improved the dielectric properties over other previously reported self-healing polymers. In addition to the abovementioned performance, we found significant differences in thermodynamic behavior in the synthesized end-modified polymers. By dielectric characterization (LCR), the breakdown composite can be left at room temperature for 60 min, and the material can recover 80 % of the initial properties without external intervention(This is demonstrated by the fact that its DC conductivity at 60 min of autonomous healing was significantly changed from that of the freshly electrically pierced DC conductivity and remained around 5.38 × 10−11 S/cm for a longer period of time thereafter). The microscopic morphology of the modified PEI matrix was observed by scanning electron microscopy (SEM) and EDS surface elemental analysis, which further supports the existence of metal coordination structures. These findings can further deepen the thinking of self-healing dielectric composites. The work inspired by this may break the limits and take self-healing composite dielectric materials to a new height.

Exploring Investment Practices in Initial Public Offerings (IPOs) among Undergraduate Students

This study aimed to explore the investment behavior of undergraduate students focusing on their participation in initial public offerings (IPOs). Data was collected through structured questionnaires from a sample of 321 students out of a total population of 1476 covering management, humanities, and education faculties. The data were collected during two-months period from April 1 to June 1, 2024. The study used exploratory research design with a quantitative approach to analyze data. The study explored that management faculty students are more likely to invest in IOPs compared to humanities faculty and education faculty students. It is also revealed that third and fourth year students were more involved in IPOs than first and second year students. Gender differences in investment behavior were also noted. Male students participate more actively in IPOs than female students. Parental education and profession did not significantly influence the investment behavior. The study pointed-out the need for targeted educational programs to improve financial literacy and informed investment decisions among students.

Understanding Sociodemographic Differences in Climate Behavior, Climate Policy Acceptance, and Political Participation

IntroductionTo mitigate the global health threat posed by climate change, multifaceted responses are required. In previous work, older, male, and highly educated individuals were shown to exhibit greater general readiness to act against climate change; the same is true for people living in larger communities. Yet, the sociodemographic effects may vary for the single facets of the readiness to act against climate change—namely individual climate-friendly behavior, acceptance of climate-protection policies, and political participation. MethodsData from four waves (2022–2023) of the Planetary Health Action Survey (PACE) were analyzed (N = 3,830, nonprobabilistic representative German sample). Sociodemographic variables (gender, age, community size, education and others) and the three abovementioned facets of the readiness to act against climate change were assessed to examine their relationships. ResultsPatterns varied between the indicators. Women and older individuals exhibited more climate-friendly behavior and policy acceptance. In contrast, levels of political participation were higher for men and younger individuals. Higher education was linked to less sustainable behavior, greater policy acceptance, and higher participation, while municipality size was only linked to the latter two. Additional analyses explore the relations between age and the constructs at item level. ConclusionsFindings underscore the importance of a nuanced understanding of people's readiness to act against climate change. Depending on communication objectives, different target groups may be relevant, e.g., do campaigners want to increase political participation vs. change individual behaviors. While older individuals exhibit greater readiness to act via individual behavior and policy acceptance, it is important to include young people in climate-communication efforts.
