Understanding inconsistencies in risk attitude elicitation games: Evidence from smallholder farmers in five African countries

Recent empirical studies eliciting farmers’ risk attitudes through lab-in-the-field experiments have reported high levels of inconsistency in responses. We investigate inconsistencies in risk attitudes elicitation games using data from incentivized lotteries involving 2,319 smallholder farmers from Eastern Africa (Kenya, Uganda, Tanzania) and Northern Africa (Tunisia, Morocco). Our sample demonstrates high levels of inconsistent behavior, with 48% of the farmers exhibiting some type of inconsistency. Depending on the country, inconsistencies are explained by poverty, gender, and/or the interaction of gender and level of education. We find no significant impact (negative or positive) of education alone in all but one country model. Furthermore, we find session fixed effects to significantly explain inconsistencies in many cases, suggesting that session-specific circumstances, including inconsistencies across enumerators, play a crucial role in the successful implementation of these experiments. Our findings suggest that using risk attitude parameters without accounting for the presence and the potential causes of inconsistency may lead to unreliable results. This study may guide practitioners in identifying farmer typologies more prone to inconsistent decisions and inform policymakers about factors influencing operators’ choices.

Impact of a natural rubber-based scratcher as an environmental enrichment on the scratching behavior, cortisol level, and semen quality of stable male goats

Background and Aim: Goats are valuable livestock because they can generate meat and milk for human consumption. Goat husbandry is becoming more intensive due to the growing demand for goat products, which may impact animal welfare and natural behavior. This study aimed to investigate the impact of natural rubber (para rubber)-based scratchers as an environmental enrichment on scratching behavior, cortisol levels, and semen quality in stable bucks (male goats/goats). Materials and Methods: Nine male goats were used in this study. Scratching behavior and cortisol levels were used as welfare indicators, whereas semen quality was evaluated as an indicator of reproductive potential. These indicators were analyzed before and after scratcher installation. Results: After installing the scratchers, the goats showed a significant increase in scratching behavior and a notable decrease in cortisol levels (p < 0.001). Notably, the goats exhibited a marked preference for scratching against the scratcher (p < 0.001) compared to the stable. They significantly preferred using their heads for scratching (p < 0.001) instead of other body parts. In addition, goats preferred to scratch on the softest rubber scratchers at specific installation locations (p < 0.001). Although there was a slight improvement in semen quality, there was no statistically significant difference (p > 0.05). Conclusion: A natural rubber-based scratcher can increase scratching behavior and reduce cortisol levels, indicating its potential to improve the welfare of farm goats. Selecting an appropriate hardness and preferred location is essential to ensure that the scratcher effectively encourages animals to use it. Keywords: cortisol, goat, para rubber, scratcher, semen quality.

Effects of the Tools for Getting Along Curriculum on Teachers’ Reports of Elementary Students’ Executive Functions, Social-Emotional Skills, and Behavior Problems

In this study, we examined the effectiveness of Tools for Getting Along (TFGA) on teachers’ reports of executive functioning (EF), social-emotional, and behavioral skills of upper elementary school students. TFGA is a classroom-level prevention curriculum that teaches students a sequence of empirically based problem-solving steps to apply in emotionally charged situations. We randomly assigned 52 elementary schools in California, Oklahoma, and Kentucky to the treatment (n = 26) or comparison (n = 26) condition, with study participants including 135 grade 4 teachers and their 1,713 students. Multilevel analyses revealed that relative to those in the comparison group, students who participated in TFGA had significantly better social skills (effect size = 0.12) and higher levels of behaviors associated with EFs (effect size = 0.11), as reported by their teachers. Further, students whose teachers reported as having higher internalizing and externalizing behaviors, lower competence, and weaker behaviors associated with EFs at baseline experienced greater improvements in these skills after participating in TFGA than their counterparts with relatively stronger skills in the comparison group. We discuss educational implications of this study to promote and scale evidence-based, social-emotional practices in elementary school classrooms.

Effects of Physical Activity Level and Sedentary Behavior on the Musculoskeletal System in Young Adults

Aim: The aim of this study is to investigate the relationship between the level of physical activity and sedentary behavior in young adults aged 18-35 and to evaluate the effects of this relationship on musculoskeletal pain, posture, muscle shortness, and trunk muscle endurance. Methods: In this cross-sectional descriptive study, conducted at the Faculty of Health Sciences of a university between March 2018 and August 2018, 219 students were included. Data were obtained by using the case report form which determines the demographic characteristics and sedentary behavior of the students, The International Physical Activity Index - short form, posture analysis form, muscle shortness evaluation form, and trunk muscle endurance evaluation form. Results: In the study, 66.2% of patients were female and 33.8% were male. In the evaluation of physical activity level, the ratio of highly active individuals in males, and inactive and insufficiently active individuals in females was significantly higher (p <0.05). Musculoskeletal pain was significantly higher in inactive and insufficiently active individuals (p<0.001). A negative correlation existed between physical activity level and pain frequency, duration, and scores (p<0.001). There was a positive correlation between trunk endurance tests and physical activity and exercise participation. Non-exercisers showed shortening of lumbar extensor muscles and gastrosoleus, with increased thoracic kyphosis (p<0.05). Daily sitting time correlated positively with elbow, wrist, and knee pain, and lumbar lordosis (p<0.05). Those spending more time at the computer experienced higher levels of head-neck and elbow pain, pain duration, muscle shortness, thoracic kyphosis, shoulder protraction, and anterior head tilt (p<0.05). Conclusion: In young adults, increasing physical activity and reducing daily sitting time are necessary to prevent musculoskeletal pain and reduce postural deformities. Keywords: Musculoskeletal diseases, musculoskeletal pain, physical exertion, posture, sedentary behavior, trunk muscular endurance, young adult.

Going the Extra Mile: What Drives Employee Voluntarism in Public Sector Organizations?

This research intends to investigate the impact of employee age and innovative work climate on the relationship between supportive supervisory roles and employee acts of voluntarism. Using a large cross-sectional survey of the Australian Public Service we find that the influence of supportive supervisors on employees’ acts of voluntarism and extra role behaviors at work is higher amongst younger employees. This indicates that younger employees are more likely to engage in acts of voluntarism as a result of supportive supervisory roles. Findings also indicate that innovative work climate accentuates the relationship between supportive supervisory behaviors and acts of voluntarism. Employees who experience high levels of innovative work climate and high levels of support from supervisors tend to display higher levels of voluntarism and extra role behaviors at work. These findings have several theoretical and practical implications.

Environmental Literacy and Pro-Environmental Behavior of Pre-Service Science Educators: The Mediating Effect of Their Climate Change Awareness

The study investigated at how climate change awareness mediates the relationship between environmental literacy and pro-environmental behavior among pre-service science educators in the Davao region, involving a total of 305 respondents. A descriptive-correlational approach was used in a non-experimental quantitative research design. The findings revealed that pre-service science educators exhibit high levels of pro-environmental behavior, environmental literacy, and climate change awareness. This finding highlights the important role of future science educators in disseminating knowledge about climate change, as persons with higher levels of environmental literacy are more likely to engage in pro-environmental actions. Climate change awareness functioned as a partial mediator, indicating that although environmental literacy is essential, climate knowledge enhances educators' involvement in sustainable practices. The findings underscore the essential function of prospective science educators in climate advocacy, indicating that educational programs may improve environmental literacy curricula and incorporate discussions on climate change, thus preparing future teachers to motivate responsible environmental actions in their communities.

Cooling lactating sows exposed to early summer heat wave alters circadian patterns of behavior and rhythms of respiration, rectal temperature, and saliva melatonin.

Heat stress (HS) exerts detrimental effects on animal production, with lactating sows being particularly vulnerable. Understanding the mechanisms involved in HS response could aid in developing effective strategies against the negative impacts on livestock. Recent genome wide association studies identified two core circadian clock genes as potential candidates in mediating HS response. The study aimed to investigate how cooling lactating sows under natural heat stress conditions impacted circadian patterns of respiration rate (RR), rectal temperature (RT), behavior, salivary melatonin and cortisol levels, and diurnal patterns of cytokines in saliva. Mixed parity lactating sows were assigned to one of two treatment groups: electronic cooling pad (C; n = 9) and heat-stressed (H; n = 9). The experiment spanned two 48 h periods of elevated ambient temperatures due to summer heat wave. In the first 48 h period, RR was recorded every 30 min, RT every 60 min, and behaviors (eating, standing, sitting, laying, sleeping, drinking, and nursing) every 5 min. In the second 48 h period, saliva samples were collected every 4 h. Cooling reduced RR and RT and altered circadian patterns (P < 0.05). Cooling did not affect amount of time engaged in any behavior over the 48 h period (P > 0.05), however, daily patterns of eating, standing and laying differed between the treatments (P < 0.05), with altered eating behavior related to RT increment in H sows (P < 0.05). Cooling increased and altered the circadian pattern of salivary melatonin (P < 0.05). Cooling also influenced the diurnal pattern of saliva cytokines. Cooling had no impact on saliva cortisol levels. In conclusion, cooling HS sows impacted circadian rhythms of physiology and behavior, supporting the need for further research to understand if circadian disruption underlies decreased production efficiency of HS animals.

Horticultural therapy impact on people with dementia

BackgroundDementia is a progressive disease, and as the disease progresses, many families seek help through activities and therapies. In contrast to some other therapies, horticultural therapy (HT) is widely accepted by most people with dementia (PWD) because it invites them to the natural world.ObjectivesTo explore whether HT emotional and communication measures (i.e. appropriate expression of emotions, ability to communicate with others) are higher than in other activities offered to PWD in adult day care centers (ADCC) and continuing care retirement community (CCRC), and whether there is a difference between the impact of HT on the number of “positive actions” (communication actions and actions that fit the guided activity) vs. the other activities.Research design and methodsFifty-one PWD attending ADCCs and living in one CCRC were recruited to a structured HT activity and other activities that took place in the ADCCs and CCRC. The activity took place over 10 weeks. The effects were assessed using Dementia Care Mapping (DCM) and questionnaires.ResultsPaired t-tests found that higher levels of mood and behavior were observed during HT activities compared to the other activities. Also, communication and function actions were higher in the HT activities as compared to the other activities.Discussion and implicationsThis study adds to the growing evidence of the benefits of HT for PWD regardless of past experience in gardening/agriculture. HT seems to provide high therapeutic benefits and should be more prevalent in centers caring for PWD.

Environmental Education and Pro-Environmental Behavior Among Um Peñaplata College Students

This study aimed to determine the level of environmental education, the level of pro-environmental behavior, and to examine the relationship between environmental education and pro-environmental behavior among UM Peñaplata College students. The research approach was quantitative, a descriptive-correlational design was employed. Thus, the researchers used mean, Pearson Product Moment Correlational, and regression for data analysis and interpretation. The results revealed that environmental education and students’ pro-environmental behavior is high. Further, there is a moderate correlation between environmental education and pro-environmental behavior among students. It underscored that students who applied an environmental value tends to be aware of how their behaviour affects the environment. The more the school integrates environmental education, the more it fosters pro-environmental behavior. Therefore, incorporating environmental education into schools enhances students’ sustainable actions towards the environment.

Motor-related oscillations reveal the involvement of sensorimotor processes during recognition memory

Certain object properties may render an item as more memorable than others. One such property is manipulability, or the extent to which an object can be interacted with using our hands. This study sought to determine if the manipulability of an item modulates memory task performance on both a behavioural and neural level. We recorded electroencephalography (EEG) from a large sample of right-handed individuals (N = 53) during a visual item recognition memory task. The task contained stimuli of both high and low manipulability. Analysis focused on activity in the theta rhythm (3.5–7 Hz), which has been implicated in sensorimotor integration, and the mu rhythm (8–14 Hz), the primary oscillation associated with sensorimotor related behaviours. At both encoding and retrieval, theta oscillations were greater over the left motor region for high manipulability stimuli, suggesting that an item’s sensorimotor properties are assessed immediately upon presentation. Manipulability did not affect activity in the mu rhythm. However, mu oscillations over the left motor region were lower during the retrieval of old versus new items and response time was faster for old items, aligning with the cortical reinstatement hypothesis. These results collectively reveal an association between motor oscillations and memory processes, highlight the involvement of sensorimotor processing at both encoding and retrieval.

The Role of Parental Involvement in the Development of Prosocial Behavior in Young Children: An Evolutionary Model Among Colombian Families

AbstractProsocial behavior is a relevant indicator of children’s socio-emotional development linked to decreased conduct and emotional problems. The present study aimed to identify cross-sectional direct effects of parental involvement on prosocial behavior in three-time assessments at ages 3, 5, and 7 years, to identify carryover effects of the study constructs, and to identify the evolution of these effects over time. A sample of 235 Colombian families participated at t0, 220 at t1, and 145 at t2 by completing self-reported questionnaires for prosocial behavior using the Strengths and Difficulties Questionnaire and the Alabama Parenting Questionnaire for parental involvement. Using PLS-SEM path modeling, we found that the contribution of parental involvement to prosocial behavior was significant in the three assessments. Carryover analyses indicated that initial levels of parental involvement and initial levels of prosocial behavior predict later levels. Using multigroup analysis, we tested significant changes in the path coefficients of direct effects, finding nonsignificant results. For carryover effects, we found changes in parental involvement between t0/t1 and t1/t2. Finally, t-test analyses were used to identify changes in the construct’s means over time, finding significant changes between parental involvement at t1 and t2. No mean differences were found for prosocial behavior. Results from this study highlight the relevance of parental involvement during childhood for maintaining children’s levels of prosocial behavior and reducing the risk of socio-emotional problems. Preventive approaches for these problems should include parents’ training on parental involvement from age 3.5 years or earlier.

The Mechanism of the Nucleus Accumbens-Ventral Pallidum Pathway Mediated by Drug Withdrawal-Induced High-Seeking Motivation in Cocaine Addiction.

The reinforcement of drug-seeking motivation following drug withdrawal is recognized as a significant factor contributing to relapse. The ventral pallidum (VP) plays a crucial role in encoding and translating motivational aspects of reward. However, current research lacks a clear understanding of how the VP mediates drug-seeking motivation and the feedback modulation between the VP and the nucleus accumbens (NAc) following drug withdrawal. Therefore, utilizing a rat model of cocaine self-administration, we investigated the circuitry mechanisms underlying drug-seeking behavior post-drug withdrawal involving the NAc-VP pathway. Initially, we observed a significant enhancement in drug-seeking behavior 14 days after cocaine withdrawal. Subsequently, we identified the feedback mechanism through which the NAc-VP regulates this behavior. Immunofluorescence results indicated an increase in c-Fos expression levels in the ventral pallidum ventromedial (VPvm) and ventrolateral ventral pallidum (VPvl) following drug withdrawal. Calcium fiber photometry further elucidated that during the expression of high motivational drug-seeking behavior, there was a specific enhancement in VPvm neuronal activity, and retrograde tracing techniques suggested a weakened transmission function in the NAc-VPm pathway. Additionally, chemical genetic techniques demonstrated that inhibiting the activity of the NAc-VP pathway could increase the motivational level of drug-seeking behavior. These findings indicate that the reduced inhibitory function of the NAc-VP pathway following prolonged cocaine withdrawal forms the basis for heightened reactivity in VPvm neurons, thus regulating the expression of high motivational behavior triggered by drug-related cues. Our study results suggest that maintaining normal NAc-VP pathway functionality may decrease drug-seeking motivation post long-term drug withdrawal, offering new insights for interventions targeting relapse.

Enhancing Learning Engagement in the Flipped Classroom using a Video-Annotation Tool

In the realm of academia, there has been a burgeoning interest in examining student engagement within the context of the flipped classroom approach, particularly at the higher education level. Nevertheless, research pertaining to a pivotal facet of this pedagogical methodology—namely, student engagement during the individualized, at-home preparatory phase—remains limited. Within this void, the primary objective of this study is to delve into the prospective benefits offered by a video annotation tool in augmenting students’ level of engagement during this autonomous study phase. Throughout the course of this investigation, a bespoke questionnaire was crafted, grounded in a multifaceted framework for evaluating student engagement, with a specific emphasis on dissecting four distinct dimensions: behavioral, emotional, agentive, and cognitive. This questionnaire is geared towards gauging student engagement within the domain of the Flipped Classroom model that relies on video-based instructional content—a facet heretofore poorly explored within the scholarly literature. Both quantitative and qualitative data were collected by administering the aforementioned questionnaire to a cohort of 68 undergraduate engineering students at Politecnico di Milano (Italy), all within the authentic context of a case study. The outcomes stemming from this empirical inquiry showcase a noteworthy enhancement in student engagement, with particular prominence accorded to the realms of emotional and agentive engagement. Moreover, this study establishes that the interactivity and proactive involvement necessitated by the video annotation tool do not obstruct students’ behavioral and cognitive engagement levels. In summation, this research endeavors to illuminate the potentiality of bridging a pivotal juncture in the Flipped Classroom paradigm, specifically the phase characterized by independent at-home study. This bridge is facilitated by the utilization of a video annotation tool designed to heighten student engagement. This transformative approach effectively transmutes the traditionally passive at-home study phase of the Flipped Classroom into an active experience, thereby enhancing the overall efficacy of this pedagogical approach.

The Impact of Puzzle Feeders, Ice-Pops and Artificial Seaweed on Captive Harbour Seals (Phoca vitulina) Behaviour

Environmental enrichment is used in zoos and aquaria to improve animal welfare through the stimulation of naturalistic behaviours and reduction of stereotypic behaviours. This study investigated the impact of new enrichment items on the behaviour of a group of captive adult harbour seals. Data were collected in summer-autumn 2023 using continuous scan sampling and all behaviours one-zero recording method for 1-minute intervals (4 hours/day, 8 days). Under standard enrichment conditions, more than 90% of the seals’ behavioural budget was represented by naturalistic behaviours, with low levels of pattern group swimming, which occurred mainly before the two daily shows. Group swimming decreased and random swimming increased before the seal shows on days with new enrichment, but these differences were not statistically significant. The presence of new enrichment items led to a significant increase in exploration and a significant decrease in group swimming only during the morning periods when the new items were actually present in the enclosure (p&lt;0.05, Kruskal Wallis test). During these periods the seals interacted most frequently with the submersed fish-filled puzzle feeders and least frequently with the floating artificial seaweed. This study concluded that new environmental enrichment may be beneficial even for seals displaying low levels of stereotypic behaviours as it provides more behavioural choices and helps promote active naturalistic exploratory behaviours which may alleviate captivity induced stress and improve welfare.

How to prevent suicidal behavior and non-suicidal self-injury? An analysis of adolescent typologies

Non-suicidal self-injury (NSSI) and suicidal behavior in adolescence are global mental health concerns. These behaviors are often interconnected, but can also manifest independently. This study aimed to assess the predictive abilities of neuroticism, emotional competencies, and the school social climate on four typologies based on the presence of NSSI and levels of suicidal behavior. The study included 713 participants aged 11–16 years who completed questionnaires assessing suicidal behavior, NSSI, neuroticism, emotional competencies, and the school social climate. The data were analyzed using logistic regression techniques. The findings revealed that adolescents with high levels of neuroticism and emotion perception, low levels of emotion expression and regulation and an inadequate school social climate were more likely to belong to typologies characterized by NSSI and/or high suicidal behavior. This study underscores the importance of enhancing the school social climate as a crucial step toward reducing the likelihood of NSSI and suicidal behavior.

An intervention on climate change anxiety and pro-environmental behaviours in Italian young people

Abstract Background The climate crisis greatly affects mental health, often leading to climate change anxiety. In Italy, there is a lack of research and school programs to help manage climate anxiety and other climate-related psychological consequences. The aim of the CAMBIO CLIMA project is to evaluate the levels of eco-anxiety and pro-environmental behaviours (PEBS) in a sample of Italian middle and high school students, before and after a tailored intervention on the climate crisis. Methods The intervention involves one hundred middle and high school classes from three Italian regions. The students will complete a set of surveys, including psychometric scales and questions on socio-demographic factors and climate change awareness. The students will then participate in a two-hour online workshop. A video will be shown at the beginning to raise awareness about climate change. The instructor will ask the students which solutions could be found to solve specific problems caused by climate change. The instructor will then propose and explain a list of PEBS that students can implement to fight against climate change. Finally, students will be invited to put into action these behaviours. A week after the intervention, students will be asked to take part in a post-intervention survey, completing the same set of questionnaires they completed at enrolment. Results Currently, the research team is in the preparatory stage, establishing contacts with schools and organizing materials for the online workshop. The intervention is scheduled for the upcoming school year. Conclusions The intervention, focused on enhancing the sense of self-efficacy, is expected to increase the resilience of adolescents, making them less vulnerable to the impact, both direct and indirect, of climate change on mental health. The project is funded by PRIN: PROGETTI DI RICERCA DI RILEVANTE INTERESSE NAZIONALE - Bando 2022 (Prot. 2022N22J5F). Key messages • Climate change has a disproportionate impact on young people. • It is essential to plan adequate school programs that stimulate the sense of awareness and encourage PEBS simultaneously.

Ethical Leadership and Organizational Citizenship Behavior in the Hospitality Industry in Bahrain: The Mediating Role of Machiavellianism

The study was conducted to determine the following: a) the level of Machiavellianism, ethical leadership, and organizational citizenship behavior (OCB) of employees in the hospitality industry; b) the significant relationship between ethical leadership and OCB, ethical leadership and Machiavellianism, and Machiavellianism and OCB; c) the mediating role of Machiavellianism in the relationship between ethical leadership and OCB. The study conducted a survey questionnaire to 27 respondents from managers and employees in the hospitality industry in the Kingdom of Bahrain. The study’s findings revealed that managers and employees have shown neutral level of Machiavellianism, with a mean of 4.04; above average ethical leadership with a mean of 3.51; and very high organizational citizenship with a mean of 3.54. Furthermore, there is a very strong positive significant relationship (Spearman rho values) between ethical leadership and organizational citizenship behavior. there is no significant relationship between ethical leadership and Machiavellianism, and that there is a weak positive relationship, but it is not significant between organizational citizenship behavior and Machiavellianism. According to the findings, very high ethical leadership in hotel employees influence their organizational citizenship behavior though Machiavellianism does not serve as a mediator in this relationship, the hospitality industry in Bahrain has much benefit to be derived from these attributes of its employees.

Real-Time Vibration Feedback from a Smartphone Application Reduces Sedentary Time but Does Not Increase Physical Activity Among Medical Students.

Background: Sedentary behavior is associated with various adverse health outcomes. Medical students often experience high academic demands, leading to increased sedentary time. This study aimed to evaluate the effectiveness of a mobile app providing real-time feedback in reducing total sedentary time and prolonged sedentary bouts and in promoting physical activity among medical students. Methods: Seventy-seven medical students from Jazan University (mean age: 21.4 years; range: 20-25 years) participated in this study. Participants were assigned to either the control group (n = 40) or the intervention group (n = 37). The intervention group received real-time vibration feedback via a mobile app, prompting movement every 30 min of sedentary time, while the control group received no intervention. Sedentary behavior and physical activity levels were assessed using the Activities Completed Over Time in 24 h. Paired t-tests were conducted to examine within-group changes, and a two-way ANOVA was used to assess the interaction effect of time and group on sedentary time and physical activity. Results: After six weeks, the intervention group showed significant within-group reductions in their total sedentary time of 1.82 h (p = 0.01) and prolonged sedentary bouts of 1.91 h (p = 0.001), while the control group had no significant changes. Physical activity levels did not significantly change within either group. The two-way ANOVA revealed that there was no significant change over time between the two groups in their total sedentary time F (1, 75) = 1.590, p = 0.21, prolonged sedentary bouts F (1, 75) = 3.499, p = 0.06, or physical activity F (1, 75) = 0.565, p = 0.45. Conclusions: Real-time feedback from mobile apps resulted in significant within-group reductions in total and prolonged sedentary time among medical students in the intervention group. Low-cost mobile apps providing real-time feedback may be an effective intervention for reducing sedentary behavior among medical students, potentially improving their health and well-being.
