A Candy Defect Detection Method Based on StyleGAN2 and Improved YOLOv7 for Imbalanced Data.

Quality management in the candy industry is a vital part of food quality management. Defective candies significantly affect subsequent packaging and consumption, impacting the efficiency of candy manufacturers and the consumer experience. However, challenges exist in candy defect detection on food production lines due to the small size of the targets and defects, as well as the difficulty of batch sampling defects from automated production lines. A high-precision candy defect detection method based on deep learning is proposed in this paper. Initially, pseudo-defective candy images are generated based on Style Generative Adversarial Network-v2 (StyleGAN2), thereby enhancing the authenticity of these synthetic defect images. Following the separation of the background based on the color characteristics of the defective candies on the conveyor belt, a GAN is utilized for negative sample data enhancement. This effectively reduces the impact of data imbalance between complete and defective candies on the model's detection performance. Secondly, considering the challenges brought by the small size and random shape of candy defects to target detection, the efficient target detection method YOLOv7 is improved. The Spatial Pyramid Pooling Fast Cross Stage Partial Connection (SPPFCSPC) module, the C3C2 module, and the global attention mechanism are introduced to enhance feature extraction precision. The improved model achieves a 3.0% increase in recognition accuracy and a 3.7% increase in recall rate while supporting real-time recognition scenery. This method not only enhances the efficiency of food quality management but also promotes the application of computer vision and deep learning in industrial production.

Nature-based cool pavements for urban overheating mitigation: Experimental proof of concept

Global warming is leading to more frequent and intense heat waves, transforming urban areas into inhospitable environments, particularly during the summer, due to the exacerbation of the urban overheating effect. Outdoor pavements, which account for 20–40 % of urban surfaces, play a crucial role in this phenomenon due to their dark colour and low albedo, resulting in high surface temperatures and the accumulation of thermal energy released into the environment. This study introduces a nature-based solution to mitigate the impact of urban overheating by cooling outdoor pavements using water from existing fountains or ponds in cities. The water functions as a coolant, significantly reducing the surface temperature of the pavement by up to 25 °C compared to dry samples exposed to the sun. The innovative aspect of this concept lies in the fact that the pavements do not exhibit capillarity, thereby achieving sensible cooling without evaporation and subsequent water consumption. The concept's impact is examined by considering pavements of varying thicknesses and albedos. In the conducted experiments, water-cooled pavements 100 % eliminated the risk of overheating compared to air temperature. This strategy offers an effective and sustainable approach to counteract the adverse effects of urban overheating in cities.

Research on the Development Strategy of Cultural and Creative Products of Libraries from the Perspective of Consumer Behavior

ABSTRACTIn recent years, there has been a notable trend and exemplary practice among libraries in effectively developing cultural and creative products. This endeavor not only foster the creative transformation and innovative development of culture, but also meets the escalating demand for high‐quality cultural consumption. Focusing on the consumption behavior of library culture and creative products in China, underscores the critical consideration for libraries, including the evolution of the consumption themes, addressing the symbolic consumption demands, creating new consumption scenarios, enhancing product quality, and augmenting consumer service awareness. Our findings highlight the importance of product diversity and aesthetic appeal, the fulfillment of commemorative value and social value, and the balancing of emotional and cognitive satisfaction in consumer demand. Moreover, the effective integration of both online and offline channels and leveraging the influence of Key Opinion Leader (KOL) are recommended marketing strategies. Regarding pricing, consumers are sensitive to price, preferring products of high quality and originality within reasonable price ranges. Finally, the study highlights the significance of enhancing the overall purchase experience and service quality, which significantly influence subsequent consumption behavior.

A Study on Carbon Emission Reduction in the Entire Process of Retrofitting High-Rise Office Buildings Based on the Extraction of Typical Models

The building sector is one of the largest contributors to carbon emissions globally, with high-rise office buildings being a major source due to their energy-intensive operations. This study aims to address the critical issue of carbon emission reductions through the retrofitting of existing high-rise office buildings, focusing on the entire life cycle of these buildings, including the embodied, operational, and demolition phases. Existing research has primarily concentrated on energy consumption and carbon emissions during the operational phase, neglecting the carbon impact of the retrofitting process itself. This research seeks to fill that gap by quantifying the carbon reduction benefits of retrofitting across all life-cycle stages. Using data from 100 high-rise office buildings in Hangzhou’s Gongshu District, five typical models were extracted based on their construction eras and architectural features. Retrofitting strategies tailored to these models were developed, and the carbon reduction benefits were calculated using the carbon emission factor method. The primary findings indicated that the shape and orientation of buildings are crucial factors influencing the carbon reduction benefits of retrofitting. Buildings oriented east–west tend to exhibit greater carbon reductions after retrofitting. During the embodied and demolition phases, retrofitting emissions remain similar for models constructed in the same era due to consistent material inputs. However, emissions vary for models from different eras, primarily due to differences in envelope materials and subsequent material consumption. High-rise office buildings constructed between 2007 and 2021 demonstrate higher overall retrofit carbon reduction rates compared to those built before 2007, despite the latter achieving greater reductions during the operational phase. The shorter remaining lifespans of pre-2007 buildings diminish their life-cycle carbon reduction advantages. Notably, complex-shaped buildings from the same era do not necessarily exhibit lower overall retrofit carbon reduction rates compared with rectangular or L-shaped buildings, with comparable reductions per unit area. This suggests that complex-shaped buildings should not be disregarded for retrofitting based solely on shape considerations. Furthermore, the remaining lifespan of a building significantly impacts its post-retrofitting carbon reduction benefits; longer lifespans result in greater benefits, and vice versa. In practical engineering applications, structural reinforcement measures can be implemented prior to retrofitting to extend a building’s structural lifespan, ultimately enhancing its carbon reduction benefits.

The Impact of Green Purchase Intention on Compensatory Consumption: The Regulatory Role of Pro-Environmental Behavior

Green purchasing behavior refers to the potential of consumers to reduce the impact on the environment and the excessive loss of natural resources in the procurement process as far as possible under the premise of meeting their own needs. This behavior is not only helpful in alleviating environmental problems but also is an important way to achieve sustainable development. However, whether consumers will increase non-green or excessive compensatory consumption behaviors due to the “moral permission” psychological tendency, present after purchasing green products, is an important question in the current research. This study explores the effect of green purchase intention on compensatory consumption behavior, with special attention to the moderating role of pro-environmental behavior in this relationship. With the increasingly severe global environmental problems, green consumption, as a pro-environmental behavior, has gradually become the focus of social attention. By analyzing the relationship between consumers’ green purchase intention and their subsequent compensatory consumption behavior, this study further reveals the important role of pro-environment behavior in the consumption decision-making process.

Anxiety and risk-taking behavior maps onto opioid and alcohol polysubstance consumption patterns in male and female mice.

Polysubstance use is prevalent in the population but remains understudied in preclinical models. Alcohol and opioid polysubstance use is associated with negative outcomes, worse treatment prognosis, and higher overdose risk; but underlying mechanisms are still being uncovered. Examining factors that motivate use of one substance over another in different contexts in preclinical models will better our understanding of polysubstance use and improve translational value. Here we assessed baseline anxiety-like and locomotive behavior and then measured voluntary consumption of multiple doses of alcohol and fentanyl in group housed male and female mice using our novel Socially Integrated Polysubstance (SIP) system. Fifty-six male (n=32) and female (n=24) adult mice were housed in groups of 4 for one week with continuous access to food, water, two doses of ethanol (5% and 10%) and two doses of fentanyl (5 ug/ml and 20 ug/ml). Our analyses revealed sex differences across multiple domains - female mice consumed more liquid in the dark cycle, had higher activity, a higher preference for both ethanol and fentanyl over water, and their fentanyl preference increased over the seven days. We then used machine-learning techniques to reveal underlying relationships between baseline behavioral phenotypes and subsequent polysubstance consumption patterns, where anxiety-and risk-taking-like behavioral phenotypes mapped onto discrete patterns of polysubstance use, preference, and escalation. By simulating more translationally relevant substance use and improving our understanding of the motivations for different patterns of consumption, this study contributes to the developing preclinical literature on polysubstance use with the goal of facilitating better treatment outcomes and novel therapeutic strategies.

The Effect of Social Support on Consumers' Variety Seeking

ABSTRACTSocial support is paramount to people's well‐being. Yet little is known about how such support influences individuals' consumption decisions in retail contexts. This multi‐method research featured five quantitative studies and showed that receiving social support can reduce consumers' variety seeking in subsequent consumption situations. Specifically, Studies 1A and 1B employed secondary data analysis, consistently revealing a negative association between social support and variety seeking. Studies 2–4 adopted experimentation approaches. Study 2 (N = 125) confirmed the proposed effect by experimentally manipulating social support. Study 3 (N = 299) shed light on the underlying mechanism by presenting a mediation model (i.e., social support → increased sense of satisfaction → decreased variety seeking). Besides, Studies 3 (N = 299) and 4 (N = 288) identified two moderators (i.e., individuals' trait gratitude and the chance to pay it forward) of the proposed effect.

Cascading sulfur cycling in simulated oil sands pit lake water cap mesocosms transitioning from oxic to euxinic conditions

Base Mine Lake (BML), the first full-scale demonstration of oil sands tailings pit lake reclamation technology, is experiencing expansive, episodic hypolimnetic euxinia resulting in greater sulfur biogeochemical cycling within the water cap. Here, Fluid Fine Tailings (FFT)-water mesocosm experiments simulating the in situ BML summer hypolimnetic oxic-euxinic transition determined sulfur biogeochemical processes and their controlling factors. While mesocosm water caps without FFT amendments experienced limited geochemical and microbial changes during the experimental period, FFT-amended mesocosm water caps evidenced three successive stages of S speciation in ∼30 days: (S1) rising expansion of water cap euxinia from FFT to water surface; enabling (S2) rapid sulfate (SO42−) reduction and sulfide production directly within the water column; fostering (S3) generation and subsequent consumption of sulfur oxidation intermediate compounds (SOI). Identified key SOI, elemental S and thiosulfate, support subsequent SOI oxidation, reduction, and/or disproportionation processes in the system. Dominant water cap microbes shifted from methanotrophs and denitrifying/iron-reducing bacteria to functionally versatile sulfur-reducing bacteria (SRB) comprising sulfate-reducing bacteria (Desulfovibrionales) and SOI-reducing/disproportionating bacteria (Campylobacterales and Desulfobulbales). The observed microbial shift is driven by decreasing [SO42−] and organic aromaticity, with putative hydrocarbon-degrading bacteria providing electron donors for SRB. Comparison between unsterile and sterile water treatments further underscores the biogeochemical readiness of the in situ water cap to enhance oxidant depletion, euxinia expansion and establishment of water cap SRB communities aided by FFT migration of anaerobes. Results here identify the collective influence of FFT and water cap microbial communities on water cap euxinia expansion associated with sequential S reactions that are controlled by concentrations of oxidants, labile organic substrates and S species. This emphasizes the necessity of understanding this complex S cycling in assessing BML water cap O2 persistence.

Underwhelming pleasures: Toward a self-regulatory account of hedonic compensation and overconsumption.

Hedonic overconsumption (e.g., overconsumption of gratifying behaviors, e.g., eating, gaming) is common in daily life and often problematic, pointing to the need for adequate behavioral models. In this article, we develop a self-regulatory framework proposing that when an actual consumption experience falls short of hedonic expectations-such as when being distracted-people will want to consume more to compensate for the shortfall. In a preliminary meta-analysis, a small-scale field experiment on distraction during lunch and subsequent afternoon snacking (Study 1), and a preregistered experience sampling study (Study 2) involving more than 6,000 consumption episodes in everyday life across multiple consumption domains, we investigated the predictions from our hedonic compensation model. There was clear and consistent evidence across studies and analyses for the prediction that distraction during consumption compromises the actual enjoyment of a given consumption experience. Both empirical studies yielded consistent evidence for a positive association between actual enjoyment and consumption satisfaction but inconsistent and weaker evidence for the expected role of actual-expected enjoyment discrepancies for this part of the model. There was also consistent evidence for the expected negative association between consumption satisfaction and the need for further gratification. Finally, there was moderate and inconsistent support linking the need for further gratification to subsequent consumption across Study 1 (amount and frequency of snacking in the afternoon) and Study 2 (shorter duration to subsequent consumption). Taken together, the present framework provides initial support for the proposed link among compromising consumption contexts, consumption enjoyment, and subsequent hedonic compensation.

Alcohol marketing on social media: young people’s exposure, engagement and alcohol-related behaviors

Aim Alcohol promotions in conventional channels are associated with subsequent alcohol consumption in young people, but little is known about young people’s exposure to digital alcohol marketing. This exploratory study investigated young people’s exposure to, and engagement with, alcohol marketing on social media platforms, variations across sociodemographic groups and associations with alcohol-related behaviors. Method An online survey was conducted with 3698 participants aged between 14 and 20 years (M = 17.1; SD = 1.8) in New Zealand. The survey asked about social media use and exposure to and engagement with alcohol product marketing on their preferred platforms, alcohol consumption patterns, hazardous drinking (AUDIT-C scores) and purchasing alcohol online. Results Nearly three-quarters of the sample who responded to questions about exposure to alcohol marketing (70.6%; n = 1541) reported seeing marketing on at least one social media platform, with older respondents (18–20 years) more likely to report exposure than younger respondents (14–17 years); no differences were found across gender, ethnicity or socioeconomic groups. Over one-third of those who responded to questions about engagement (40.7%; n = 850) reported engaging with alcohol marketing and this varied by age, gender and ethnicity. Recall of exposure to alcohol marketing was less strongly associated with online purchase and having ever drunk alcohol than was engagement with alcohol marketing, which was also associated with hazardous drinking. Conclusions Engagement with alcohol marketing was more strongly related to alcohol behaviors, including online purchasing, having ever drunk alcohol, and drinking at hazardous levels, than exposure. These findings also demonstrated inequitable patterns of engagement with alcohol marketing on social media associated with these novel algorithmic marketing methods.

Nexus Between Water Consumption and Economic Output for the Metallic and Non‐Metallic Mineral Products Sector: An Empirical Analysis at the Enterprise Level

AbstractWith rapid urbanization and industrialization in China, the demand for mineral products and subsequent water consumption have significantly increased, posing challenges to sustainable economic growth due to escalating water scarcity. Few studies have explored the nexus between water use and economic output from the enterprise perspective. This study focuses on the metallic and non‐metallic mineral products sector, quantifying the nexus between water consumption and economic output at the enterprise level, analyzing the heterogeneity of water consumption elasticity of economic output across different regions and sub‐sectors, and identifying key sub‐sectors within each region that are highly dependent on water consumption. The results indicate that for the metallic and non‐metallic mineral products sector, a 1% increase or decrease in water consumption leads to a corresponding increase or decrease in economic output by 0.096%. Water consumption elasticity of economic output varies from 0.056 to 0.131 according to the regions. And it ranges from 0.048 to 0.104 for different sub‐sectors. This study identifies regions and sub‐sectors where economic output is highly dependent on water resources. The findings may help tailor policies to measure the value of water, especially in the context of potential water shortages.

Follow-up to Adolescence after Early Peanut Introduction for Allergy Prevention

BackgroundA randomized trial demonstrated consumption of peanut from infancy to age 5 years prevented the development of peanut allergy. An extension of that trial demonstrated the effect persisted after 1 year of peanut avoidance. This follow-up trial examined the durability of peanut tolerance at age 144 months after years of ad libitum peanut consumption.MethodsParticipants from a randomized peanut consumption trial were assessed for peanut allergy following an extended period of eating or avoiding peanuts as desired. The primary end point was the rate of peanut allergy at age 144 months.ResultsWe enrolled 508 of the original 640 participants (79.4%); 497 had complete primary end point data. At age 144 months, peanut allergy remained significantly more prevalent in participants in the original peanut avoidance group than in the original peanut consumption group (15.4% [38 of 246 participants] vs. 4.4% [11 of 251 participants]; P<0.001). Participants in both groups reported avoiding peanuts for prolonged periods of time between 72 and 144 months. Participants at 144 months in the peanut consumption group had levels of Ara h2-specific immunoglobulin E (a peanut allergen associated with anaphylaxis) of 0.03 ± 3.42 kU/l and levels of peanut-specific immunoglobulin G4 of 535.5 ± 4.98 μg/l, whereas participants in the peanut avoidance group had levels of Ara h2-specific immunoglobulin E of 0.06 ± 11.21 kU/l and levels of peanut-specific immunoglobulin G4 of 209.3 ± 3.84 μg/l. Adverse events were uncommon, and the majority were related to the food challenge.ConclusionsPeanut consumption, starting in infancy and continuing to age 5 years, provided lasting tolerance to peanut into adolescence irrespective of subsequent peanut consumption, demonstrating that long-term prevention and tolerance can be achieved in food allergy.

Statistical adaptive modeling for kitchen waste detection in complex scenes

Automatic detection of kitchen waste is of great significance, which provides support for its subsequent full quantitative consumption and harmless treatment. In addition, manual sorting of kitchen waste is inefficient and toxic waste is harmful to human health, making automatic detection of kitchen waste technology crucial. Automatic detection of kitchen waste in complex scenes faces the challenge of diversity of category outlines and uneven distribution. In this paper, we propose a detector based on statistical adaptive modeling(namely SA-Det) for the automatic detection of kitchen waste in complex scenes. Firstly, to solve the issue of diversity of category outlines, we propose a category statistics adaptive (CSA) module. The CSA module constructs dynamic thresholds for each instance to accurately assign positive and negative samples by fusing category statistics and instance shape information, thereby improving detection performance. Moreover, to solve the issue of uneven distribution, we propose a distribution adaptive (DA) module, which dynamically adjusts the loss weights by adaptively sensing the number of labels during training process. Extensive experiments on our constructed kitchen waste dataset (KWD) demonstrate that SA-Det consistently and significantly improves the performance of existing state-of-the-art methods (e.g., Rotated_RetinaNet (Lin et al., 2017) and RoI_Transformer (Ding et al., 2019)) by around 2% to 3.5%.

104 Effects of providing vitamin and mineral supplementation throughout gestation on subsequent F1 replacement heifer liver and muscle oxygen consumption and mitochondrial function throughout pregnancy

Abstract The study aimed to assess the impact of maternal vitamin/mineral supplementation during gestation on the energy utilization in liver and muscle tissues of F1 heifer offspring. We hypothesized that VTM supplementation during gestation would mitigate mitochondrial energy loss and uncoupling of liver and muscle tissue in pregnant offspring. At breeding, crossbred Angus heifers [n = 31; initial body weight (BW) = 412.5 ± 53.68 kg] were randomly assigned to either a basal diet targeting BW gains of 0.45 kg•heifer-1•d-1(CON; n = 14) or the basal diet plus 113 g•heifer-1•d-1of a vitamin/mineral supplement (VTM; n = 17). Heifers remained on their respective dietary treatments until calving. After calving, all F1 heifer calves were raised in a single management group with their dams until weaning (BW = 209 ± 4.82 kg; VTM, n = 17; CON, n = 12) and fed a common diet throughout postnatal development. At breeding and throughout gestation, F1 heifers (n = 9, VTM; n = 7, CON) were allotted daily feed intakes of 1.5% of BW on a dry-matter basis as a total mixed ration and used to evaluate cellular energy metabolism throughout pregnancy. Liver and Longissimus dorsi muscle biopsies were collected on d 179 and d 247 +/- 3 of gestation and mitochondrial function was assessed via high resolution respirometry (Oroboros Instruments, Innsbruck, Austria). The following respiratory states were evaluated: LEAK respiration (L), OXPHOS capacity (P), NADH-linked OXPHOS (PI), and electron transfer capacity (E). Data were analyzed using the MIXED procedure of SAS with repeated measures where appropriate. No treatment × trimester interaction (P ≥ 0.13) was observed for any of the respiratory states in liver and muscle. Hepatic oxygen consumption was not influenced by maternal gestational VTM supplementation (P ≥ 0.68), or stage of gestation (P ≥ 0.27). In muscle, L respiration was the only state affected by maternal dietary treatments, being greater (P = 0.05) in CON than VTM heifers. Additionally, L respiration was greater (P = 0.02) during the third trimester compared with the second trimester. This observation in CON heifers is important because increased L respiration (proton leak) results in decreased ATP production. Protons that escape the intermembrane space, are dissipated as heat rather than be used for ATP synthesis; thus, oxygen consumption increases to compensate for the reduction of protons entering ATP turnover. Results show increased muscle mitochondria inefficiency in offspring with dams lacking supplementation during pregnancy. The increased incidence of proton leak results in potentially less efficient cattle as protons escape the electron transport chain rather than be transformed for energy utilization need of the animal, thus VTM supplementation throughout pregnancy impacts fetal development with potential effects in live offspring 18 to 22 mo post-parturition.

Morphological Characteristics of Colon Tumors in Mice with Different Tolerance to Hypoxia.

In adult male C57BL/6 mice with high (HR) and low (LR) resistance to hypoxia, morphological features of colon tumors and blood parameters were evaluated 70 days after intraperitoneal injection of azoxymethane and subsequent consumption of 3 cycles of dextran sulfate sodium. On macroscopic analysis, tumors were found in the distal colon in 35% (7 of 20 animals) of HR and 31% (4 of 13 animals) of LR animals. Microscopic analysis of the distal colon revealed tumors in 75% (15 of 20 animals) of HR and 69% (9 of 13 animals) of LR mice. The tumors were presented by areas of glandular intraepithelial neoplasia and adenocarcinomas; the incidence and the area of the tumors did not differ in groups of HR and LR mice. The number of neuroendocrine and goblet cells in the distal colon mucosa in the areas of tumors was similar in the compared groups. However, in both HR and LR mice of the experimental groups, the content of goblet cells in tumors was lower and the content of endocrine cells was higher than in the corresponding control groups. In the peripheral blood, the erythrocyte count and hemoglobin content decreased in HR and LR mice of the experimental groups; the relative number of monocytes increased only in HR mice and the absolute number of lymphocytes and monocytes decreased in LR mice. Thus, 70 days after azoxymethane administration and dextran sulfate sodium consumption, the tumors in mice were presented by glandular intraepithelial neoplasia and adenocarcinomas, and their incidence and area did not differ between animals with different tolerance to hypoxia.

Collective influence: How the collection mindset shapes consumer spending and price perceptions

AbstractCollection has become a significant form of consumption in consumers' lives. However, to date, our understanding of the downstream behaviors associated with collection consumption remains limited. Could collection have a more extensive impact on consumers' subsequent behaviors? Across four experiments and one field study, results indicate that adopting a collection mindset can shift consumers' perceptions of price changes, influencing their subsequent consumption. This effect arises, because when consumers possess a collection mindset, they lean towards hedonic (as opposed to utilitarian) evaluations of objects. Consequently, such consumers are less sensitive to price fluctuations, leading them to spend more in subsequent unrelated purchases. Furthermore, two studies demonstrate that the influence of collection consumption on price sensitivity is moderated by the nature of the collection and consumers' motivations for collecting. Given the pervasive role of collection consumption in consumers' lives, this research offers crucial theoretical and practical insights.

Green building future: algal application technology

In the context of rising global energy demands driven by population growth and urbanization, the construction industry significantly contributes to greenhouse gas emissions during the construction phase and subsequent energy consumption. Fossil fuel dependency for heating and energy needs exacerbates climate change, necessitating urgent solutions. Algal technology emerges as a promising strategy for green building practices, addressing energy efficiency and emissions reduction. Algae's unique ability to absorb carbon dioxide (CO2) through photosynthesis is harnessed by deploying photobioreactors on building exteriors. Studies indicate that each kilogram of dry algae consumes 1.83 kg of CO2 while offering applications as organic fertilizer, oil, and protein sources. This technology not only diminishes CO2 emissions but also transforms wastewater and generates bioenergy, catering to building energy requirements. Algal technology's economic and environmental significance becomes evident through carbon capture, energy generation, and circular waste management, aligning with sustainability principles. This study highlights the potential of algal technology to shape the future of eco-friendly conscious construction practices, providing avenues for reduced emissions, efficient energy utilization, and sustainable development.

The role of awareness of circular economy’s concept in purchase of sustainable goods and access-based and collaborative consumption – Porto case

PurposeCircular economy (CE) is receiving increasing worldwide attention as a manner to overcome the challenges linked to current trends of unsustainable energy and resource consumption. This paper aims to fill this gap and analyze the adherence to sustainable, access-based and collaborative consumption practices by exploring the role of CE awareness, specifically in the context of Porto, the second-largest city of Portugal.Design/methodology/approachThe methodology of choice is quantitative, based on partial least square-based structural equation modeling.FindingsThe result shows that there is an influence of CE awareness on subsequent sustainable consumption models.Research limitations/implicationsPresent research contributes to the theory on CE awareness and sustainable consumption. It proposes a model that could be applied in other countries. As this research is developed within the city of Porto, it may limit generalizations of obtained results.Practical implicationsAs CE practices are embodied into national and local policies, this research contributes to understanding local contexts of CE practices dissemination, providing practical suggestions for businesses and policymakers aiming the transition to the CE.Originality/valueAn original approach to measuring the awareness of CE economy is proposed, that is analyzed not only from the familiarity perspective but in six dimensions of its construction: familiarity, importance, perception or interpretation, advantages, social impact and barriers in this process. Further, the conceptual model of the impact that these dimensions have on the adoption of sustainable consumption models (purchase of sustainable products, access-based and collaborative consumption) is proposed.

Relationship between childhood stressful events and drug consumption among university students

IntroductionThe purpose of this study is to investigate the potential relationship between stressful events experienced in childhood and subsequent toxic substance consumption among university students majoring in Social Education at a Spanish university during the academic year 2022-2023.ObjectivesThe primary objective is to analyze whether an association exists between stressful life events in childhood and patterns of substance consumption among university students.MethodsA cross-sectional, observational, and analytical design was employed. The target population encompassed 258 students enrolled in the Social Education program in 2023. The final sample consisted of 161 students. A questionnaire incorporating the Childhood Trauma Questionnaire - Short Form (CTQ-SF) and the Severity of Dependence Scale (SDS) was administered to assess trauma history and substance consumption.Results A high percentage (95.03%) of students reported having consumed toxic substances at some point in their lives. The most common substances were alcohol (95.03%) and cannabis (52.8%). A statistically significant correlation was observed between childhood emotional abuse and increased alcohol consumption currently (p = 0.015). Furthermore, a significant relationship was identified between childhood sexual abuse and heightened alcohol consumption (p = 0.015). Moreover, positive correlations were found between sexual abuse and the consumption of specific drugs, such as cocaine and psychopharmaceuticals (p &lt; 0.05).No statistically significant differences were observed in drug consumption with regard to other forms of childhood maltreatment, such as emotional or physical neglect.Conclusions The results underscore the connection between childhood stress experiences and substance consumption among university students. Emotional and sexual abuse in childhood are linked to higher alcohol consumption and, in some cases, specific drugs like cocaine and psychopharmaceuticals. These findings emphasize the importance of considering traumatic experiences when addressing prevention and treatment strategies for substance consumption among young student populations.Disclosure of InterestNone Declared

How and when does a used (vs. unused) account affect consumption behavior?

How does spending from a used (vs. unused) account affect consumption behavior? An account is used when some resources of that account have been used (e.g., $90 has been used on a gift card that originally had $100). An account is unused when no resources of that account have been used (e.g., no money has been used on a gift card that has $10). Across seven studies (N = 8,667), we find that people are more likely to spend resources from a used account than otherwise equivalent resources from an unused account. This is because people engage in within-account comparisons, comparing the remaining resources in the account with what the account originally had, leading them to value the remaining resources less in a used account. We demonstrate the robustness of the effect of a used (vs. unused) account across several domains, including gift cards, checking accounts, and credit card reward points. Further, we demonstrate a boundary condition of the effect, revealing that the proportion of the account remaining moderates the subsequent consumption. Lastly, we generalize this effect from consumption to charitable giving. The findings provide insights into how policymakers, companies, and individuals may consider leveraging the perception of an account being used or unused to curb expenses and encourage charitable giving.
