We collaborated with a leading fast-moving consumer goods (FMCG) manufacturer to investigate how intelligent image processing (IIP)-based shelf monitoring aids manufacturers' shelf management by using data from a quasi-experiment and a field experiment. We discovered that such artificial intelligence (AI) assistance significantly and consistently improves product sales. Several underlying mechanisms were revealed by our quantitative and qualitative analysis. First, retailers are more likely to comply due to the greater monitoring effectiveness enabled by AI assistance. Second, the positive effect of IIP-based shelf monitoring partially persists after it is terminated, implying that human learning takes place. Third, the value of IIP-based shelf monitoring can be attributed to independent retailers rather than chain retailers. Since the degree of contract heterogeneity is the major difference between these retailers in terms of monitoring, this finding further suggests that AI is relatively more scalable when coping with more heterogeneous instances. Apart from these great benefits, we demonstrate the low marginal costs of implementing IIP-powered shelf monitoring, which indicates its long-term applicability and potential to generate incremental value. Our research contributes to several literature streams and provides managerial insights for practitioners who consider AI-assisted operational models. [ABSTRACT FROM AUTHOR]

New roads bring new opportunities including access to employment. However, new employment opportunities might encourage early school dropout and school absenteeism. We investigate the link between rural roads, children's labor allocation, and educational outcomes by focusing on the recent Ethiopian road construction program. In the analysis, we combine household panel data with novel road network data. To address endogeneity concerns, we combine a difference-in-difference estimation model with a matching technique. Our findings consistently show that road access does not encourage school absenteeism or school dropouts to join the labor force. The findings remain consistent across gender and age groups.

This paper describes the implementation and evaluation of RADAR (Response Awareness, De-Escalation, and Referral), a hybrid CIT/co-response program for people with behavioral health issues (PBHI). RADAR emphasized information sharing between police, PBHI, and behavioral health professionals and targeted outreach to PBHI by a police officer and clinician working in partnership. We evaluated RADAR using a quasi-experimental analysis of calls for service and incident data, an officer survey, and interviews with key personnel. While RADAR did not significantly reduce calls, incidents, or physical contact and resistance relative to a comparison jurisdiction, the survey and interviews suggest that it did help to shift the department’s culture and organizational perceptions around collaborative responses to PBHI. The practical implications of our findings for police agencies seeking to implement co-responder programs include the need to focus on sustainability; relationship building between the police, PBHI, and clinicians; and technological solutions to improve data collection and evaluation efforts.

In the ecosystem of artificial intelligence (AI), generative models enable the creation of hyper-realistic manipulations that are extremely plausible due to the precision of the audiovisual objects. These deepfakes are undetectable thanks to their components, which heightens concerns about the distortion of reality in the information ecosystem and how the ability to distinguish between real and fake audiovisual content affects public trust and democratic systems. This is a major challenge for media and information literacy if it is to combat misinformation effectively. In this context, this study presents the results of a quasi-experiment conducted with 80 young people from the Community of Madrid (Spain) to assess their ability to detect deepfakes in immersive environments and to establish whether the context-identifying elements that enable detection of the reputation of the media source shape the credibility of the images. The results show that the images take precedence over the context identifiers, preventing a critical reading of the information that would make it possible to detect visual forgeries, something that is reinforced by their exceptional verisimilitude. It is concluded that the new post-humanist biome of virtual reality and artificial intelligence requires a reorientation of media and information literacy to raise the public's awareness and educate them to make them less susceptible to disinformation based on deepfakes created with generative models.

Interactive picturebook reading is an easily accessible and enjoyable activity that provides preschoolers with opportunities to practice problem-solving skills. Increasingly, preschool age is considered the ideal time to foster problem-solving skills. This paper examines the effect of interactive picturebook reading on the problem-solving skills of preschool children. A total of 130 preschool children between 4 and 6 years old participated in a pretest–posttest quasi-experiment with a non-equivalent control group. During five interactive reading sessions in small groups, preschoolers were invited to discuss possible solutions to the problems the book characters encounter. Problem-solving skills were measured with two Pictorial Multiple-Solutions Tasks. Multilevel analysis indicates that interactive picturebook reading can improve children's flexibility, fluency, and originality in coming up with possible solutions to a problem. In addition, we found that the picture that was used and the emotional reactions of the children to the test situation influenced the test scores. The results show that giving children the opportunity to discuss possible solutions to problems presented in picturebooks is an effective way to work on problem-solving skills in preschool. Further research is needed to explore the optimal conditions for effective interactive picturebook reading to develop preschoolers' problem-solving skills and the extent to which the skills demonstrated during interactive picturebook reading can be transferred to real-life problem solving.

The European Youth Strategy and its tools are pivotal instruments within the European Union policies framework to meet the varied needs of young citizens while fostering a sense of European citizenship. However, the extent of those tools' impact lacks empirical evidence in the existing literature. To address this gap, we employed a quasi-experimental post-test design with both intervention and control groups across four countries. Underpinned by the Social Cognitive Theory, our research aimed at unveiling insights into the effects of an intervention focused on raising awareness about the European Youth Strategy as part of an EU project on the participants' European citizenship self-perceptions. The intervention consisted of workshops and informational sessions aimed at enhancing participants' understanding of the European Youth Strategy. Using an adapted Global Citizenship Scale, we conducted an online survey among 1403 individuals aged 18 to 24 with mixed results. The results showed varied outcomes, ranging from positive effects in Slovakia to neutral effects in Romania and Hungary and negative impacts in Bulgaria. Females tended to respond more positively to the intervention than males, though this was evidenced primarily in Hungary and Slovakia. These findings suggest that country-specific cultural and contextual factors play a crucial role in shaping the effectiveness of such interventions. Consequently, our research offers crucial comparative data for evaluating European citizenship projects, presenting nuanced insights into the targeted EU member states. It contributes to the limited empirical literature on the impact of the European Youth Strategy and underscores the need for more targeted, context-sensitive approaches in promoting European citizenship among youth. Future research should consider longitudinal designs to capture long-term effects and investigate further the mechanisms behind the observed gender differences. [ABSTRACT FROM AUTHOR]

This study considers ways to increase the consumption of sustainable fashion given the significant environmental and social damages associated with the industry. A series of experiments were conducted examining the impacts of choice architecture (nudges) under field conditions in collaboration with one of Israel's largest shopping centers. This study sought to identify which interventions at the retail level successfully motivate sustainable fashion behavioral change regarding purchases and willingness to pay more, along with agreement with several statements regarding the climate crisis and sustainable fashion. Among the types of nudges examined in this field study were providing information, increasing accessibility to sustainable alternatives and appealing to social identity in relation to demographics and green self-image. This study found that offering alternatives to consumers constituted the most effective way to "nudge" consumers toward more sustainable purchasing behavior. Nonetheless, this does not negate the contribution of providing information and strengthening social norms regarding sustainable fashion. Additionally, in all groups, most participants reported that they did not know how to distinguish between sustainable and non-sustainable fashion, nor did they believe that the clothes they purchased were actually sustainable. The findings emphasize the need for policies that will increase the accessibility of sustainable fashion. [ABSTRACT FROM AUTHOR]

Information infrastructure development substantially impacts the transformation of enterprises' decision-making. Based on the "Information Consumption Demonstration City Construction" policy issued by the Chinese Ministry of Industry and Information Technology in 2016, we conducted a quasi-experiment to examine the effects and mechanisms of information infrastructure construction on the enterprise's environmental, social, and governance (ESG) performance. Overall, information infrastructure construction was shown to substantially improve the ESG performance of these companies and exhibit a strong promoting effect on labor-intensive and state-owned enterprises. Regarding internal mechanisms, the information infrastructure has accelerated the digital transformation of enterprises and improved information efficiency, which is beneficial for suppressing opportunistic behavior. Regarding external mechanisms, information infrastructure development and ESG investment have jointly reduced corporate financing constraints, improving their credit market performance. These findings provide substantial practical evidence for promoting the construction of an information infrastructure from the perspective of enterprise governance transformation.

Objective: Psychoactive substance use is prevalent among young people in Nigeria. However, the dearth of accessible and good-quality treatment for substance use disorders in Nigeria creates a treatment gap. This study evaluated the effectiveness of a substance use prevention education programme (SUPEP) for young people in Nigeria. Design: A quasi-experimental study using a pre–post-test was conducted. The experimental group (n = 100) and comparison group (n = 100) comprised students in four senior secondary schools. Data were collected using a validated self-report questionnaire and the WHO Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST) version 3.0. Paired sample t -tests, analysis of covariance (ANCOVA) and generalised and linear mixed models (GLMM) were used for data analysis. Setting: Two hundred young people aged 14–20 years prone to substance use participated in SUPEP in four secondary schools in Enugu State, Southeast, Nigeria. Results: Students' psychoactive substance knowledge and substance use attitudes in the experimental group (p <.001) improved significantly post-intervention. ANCOVA results showed that the mean psychoactive substance knowledge score increased significantly between the time points, F (1, 123) = 8.89, p =.003. In contrast, mean psychoactive substance use attitudes reduced significantly between the same time points, F (1, 123) = 12.390, p =.001. However, no significant difference between the groups was observed in the mean psychoactive substance use behaviour post-intervention. Conclusion: The school-based SUPEP increases psychoactive substance knowledge and improves attitudes. However, the intervention did not reduce substance use among adolescents. [ABSTRACT FROM AUTHOR]

In the current socio-political climate, there is an extra urgency to evaluate whether program impacts are distributed fairly across important student groups in education. Both experimental and quasi-experimental designs (QEDs) can contribute to answering this question. This work demonstrates that QEDs that compare outcomes across higher-level implementation units, such as schools, are especially well-suited to contributing evidence on differential program effects across student groups. Such designs, by differencing away site-level (macro) effects, on average produce estimates of the differential impact that are closer to experimental benchmark results than are estimates of average impact based on the same design. This work argues for the importance of routine evaluation of moderated impacts, describes the differencing procedure, and empirically tests the methodology with seven impact evaluations in education. The hope is to encourage broader use of this design type to more-efficiently develop the evidence base for differential program effects, particularly for underserved students. [ABSTRACT FROM AUTHOR]

Enabling older adults to age at home is an urgent issue. This study focuses on the attitudes of middle-aged and older people (MAOP) in the capital cities of Taiwan, which are characterised by expensive housing prices and living costs, to examine their preferences for reverse mortgage (RM) schemes. The stated preference method and conditional multinomial logit model are utilised for analysis. The study simulates the total payment duration (TPD) and monthly payment amounts (MPA) to determine the market share of MAOPs' choices regarding terms. The results indicate that MAOPs tend to opt for RM schemes when they have children, partly enhancing the preference toward the long-term alternative (AL). Increasing the MPA has a positive effect on the market share of the AL scheme, but the amount must be increased to 90% to replace the market share of non-participation schemes significantly. The experimental design of this study could serve as a reference for future RM scheme designs. The findings suggest that there should be more alternative funding sources in an ageing society, particularly through revitalising housing assets, to promote ageing in place. [ABSTRACT FROM AUTHOR]

The career ladder system has proven to be effective in supporting nurses' professional development. However, its implementation has not been optimal, partly due to nurses' low motivation. Therefore, a strategy to develop an electronically integrated career ladder information management system, SIMCAR LASTRI, is needed to improve career ladder implementation. This study aims to analyze the effect of SIMCAR LASTRI development on nurses' motivation in implementing career ladder in Tanjungpinang. This study used an analytic quantitative method with a pre-post quasi-experiment design without a control group. Application development was conducted through ADDIE (Analyze, Design, Development, Implementation, Evaluation) and RAD (Rapid Application Development) methods. The research subjects were executive nurses (n=76) with total sampling. Bivariate tests were conducted using the Wilcoxon Signed Rank Test. The results showed a significant effect on nurses' motivation before and after using the web-based SIMCAR LASTRI application, with a p value = 0.000 <0.05. The implementation of webbased SIMCAR LASTRI is feasible and has a significant influence on nurses' motivation in implementing career paths. SIMCAR LASTRI application can be implemented in all hospitals. [ABSTRACT FROM AUTHOR]

Objectives : This study investigates the effects of the length of imprisonment on reoffending after release. Methods: To account for endogeneity from omitted variables that influence both sentencing decisions and the likelihood to reoffend, this study uses variation in the proclivity to impose lengthier sentences across judges to which criminal cases are randomly assigned within district courts in the Netherlands. Using administrative data on all adult offenders convicted to short-term imprisonment (≤ 1 year) by a single-sitting judge in the Netherlands in 2012, we estimate multiple instrumental variable models. Results: The results indicate that an increase in imprisonment length significantly reduces the amount of offenses committed after release, whereas we only find small and statistically non-significant estimates for the probability to recidivate. Conclusions: We find evidence for a specific preventative effect of longer prison terms on the post-release reoffending frequency, but little evidence for desistance. [ABSTRACT FROM AUTHOR]

The randomized control trial (RCT) is the primary experimental design in education research due to its strong internal validity for causal inference. However, in situations where RCTs are not feasible or ethical, quasi-experiments are alternatives to establish causal inference. This paper serves as an introduction to several quasi-experimental designs: regression discontinuity design, difference-in-differences analysis, interrupted time series design, instrumental variable analysis, and propensity score analysis with examples in education research.

We examine the impact of firm social media engagement on sales performance, answering “whether,” “what,” and “how” questions. The study uses a quasi-experimental design in a social e-commerce setting, for which propensity score matching and difference-in-differences methods quantify a mean 20.67% sales increase after firm social media adoption. We also find that firms that sell low-involvement products benefit more from social media adoption, compared to those that sell high-involvement products. Further, in terms of how to manage social media engagement, we find that informative content, in general, is effective for sales of high-involvement products, whereas promotional content, a new type of content discovered in this study, is more beneficial for sales of low-involvement products. Meanwhile, more social media followers generate better firm sales performance. We used instrumental variables and the control function method to address endogeneity issues and conducted robustness checks to support our conclusions. This study sheds light on the value of firm social media, particularly regarding industry differences and firm know-how. [ABSTRACT FROM AUTHOR]

Abstract Background Wolbachia symbiosis in Aedes aegypti is an emerging biocontrol measure against dengue. However, assessing its real-world efficacy is challenging due to the non-randomised, field-based nature of most intervention studies. This research re-evaluates the spatial–temporal impact of Wolbachia interventions on dengue incidence using a large battery of quasi-experimental methods and assesses each method’s validity. Methods A systematic search for Wolbachia intervention data was conducted via PubMed. Efficacy was reassessed using commonly-used quasi-experimental approaches coupled with extensive robustness checks, including geospatial placebo tests and a simulation study. Intervention efficacies across multiple study sites were computed using high-resolution aggregations to examine heterogeneities across sites and study periods. We further designed a stochastic simulation framework to assess the methods’ ability to reproduce true intervention efficacies (IE). Results Wolbachia interventions in Singapore, Malaysia, and Brazil were associated to significant decreases in dengue incidence, with reductions ranging from 48.17% to 69.19%. IEs varied with location and duration. Malaysia showed increasing efficacy over time, while Brazil exhibited initial success with subsequent decline, hinting at operational challenges. Singapore's strategy was highly effective despite partial saturation. Simulations identified Synthetic Control Methods (SCM) and its variant, count Synthetic Control Method (cSCM), as superior in precision, with the smallest percentage errors in efficacy estimation. These methods also demonstrated robustness in placebo tests. Conclusions Wolbachia interventions exhibit consistent protective effects against dengue. SCM and cSCM provided the most precise and robust estimates of IEs, validated across simulated and real-world settings.

The fast-growing sensing technology means there is an extensive range of low-cost indoor air quality (IAQ) devices or sensor modules readily available on the commercial market. However, less attention has been paid to exploring people's perceptions and responses to indoor air pollution. Such knowledge is deemed important for improving the design of future IAQ sensors, enhancing public awareness and providing guidance on ways to improve indoor environmental conditions. This study aimed to explore people's perceptions and responses to IAQ under different quasi-experimental environmental conditions and levels of information. The study is reported from the perspective of 16 staff and students at a UK university, held within a prototype smart and modular home built on campus. It compares questionnaire survey responses and focus group interview discussions with actual IAQ concentrations and other influential indoor parameters (indoor air temperature and relative humidity). Study outcomes revealed the importance of understanding contextual factors when developing feedback and communication strategies to best improve people's awareness, acceptance, and behavioural responses to IAQ. Findings highlight the usefulness of focus group discussions in the design of future IAQ sensors. [ABSTRACT FROM AUTHOR]

This study estimates the effects of women's education on their offspring using quasi-experimental evidence from six educational reforms that increased the length of compulsory schooling in several European countries. The empirical analysis uses data from the Survey of Health, Ageing and Retirement in Europe and instrumental variable estimation to estimate the effects of female education on fertility and on children's education. This study provides the first analysis using quasi-experimental variation in education to estimate prospective models of intergenerational effects. These models start with a birth cohort and link information on their fertility and on their children's outcomes. These models account for the effect of female education on the probability that women have children when estimating the effect of female education. The direct effect of female education on children's educational attainment, i.e. the effect conditional on the birth of a child, is positive. In addition, higher female education increases fertility. Therefore, the probability that a woman has a child with a high educational attainment is increased when considering the effect of female education on fertility. Studies that estimate retrospective models of intergenerational effects using reforms in the length of compulsory schooling may underestimate the total effect of female on child education.

Breast milk is optimal for both term and preterm infants as it provides essential nutrition and immunity. However, mothers of preterm infants often have insufficient milk supply, resulting in low breastfeeding rates, including in Thailand, where this quasi-experimental study was undertaken. We investigated the effects of an early breastfeeding education and proactive telephone support program, including early breastfeeding education and proactive telephone support. This included breastfeeding outcomes, including total breast milk volume, duration of exclusive breastfeeding, and exclusive breastfeeding rates at discharge and three months post-discharge in mothers of preterm infants. The participants included 57 mother-infant dyads and their families. The participants were assigned to either the control group (n = 28) receiving routine care or the experimental group (n = 29) receiving the intervention program. The assignment was done using purposive sampling and matching the number of pregnancies and gestational age between the two groups. Data were collected using the Demographic Characteristics Questionnaire, the Breast Milk Expressing Record Form, the Oral Care with Breast Milk Record Form, and the Breastfeeding Practice and Problems Record Form. Data analysis was performed using the chi-square test, Mann-Whitney U test, independent t-test, and descriptive statistics. The results indicated that, after receiving the program, the total breast milk volume from day 1 to day 7 and the duration of exclusive breastfeeding in the experimental group were significantly higher and longer than in the control group. At discharge, the rate of exclusive breastfeeding in the experimental group was higher than that of the control group but with no statistical difference. However, the experimental group had a significantly higher exclusive breastfeeding rate at three months than the control group. This study confirmed the program's effectiveness in increasing the exclusive breastfeeding rate at three months. Nurses can integrate this program to promote breastfeeding as a critical component of preterm infant care. Still, a long-term follow-up study requires comprehensive testing of its effectiveness.

Matching makes or breaks peer-to-peer (P2P) platforms. As the platform-based P2P markets shift from their grassroots nature toward elite offerings, will differentiating suppliers by quality increase matching performance? Can P2P markets differentiate certain suppliers without marginalizing others? We seek answers to these questions by leveraging an empirical opportunity on Airbnb, which differentiates listings that meet high quality standards from others through its Plus program in several U.S. cities. Our findings are threefold. First, we find a sizable increase in market-level matching performance after the program launch, that is, a 15.8%–16.2% increase in the number of booked nights. Second, the rise in matching performance is attributed to reduced search frictions, evident in markets with higher discovery and evaluation costs. Third, the Plus program benefits all listing tiers through reduced search frictions, yielding the most benefits to the Plus and non-Plus listings in terms of increased bookings and prices. Regular listings also receive increased bookings because of competitive prices. Our findings hold across multiple robustness checks and offer important insights for platform design and supply management in P2P markets.

BackgroundMethodResultsConclusionCreative arts-based interventions are a relatively new addition to the toolkit of psychological treatments for mental afflictions. As such, the therapeutic efficacy of these therapies when conducted remotely via digital media has been under-researched. To address this gap, this study tested the effects of an online creative arts-based intervention to alleviate anxiety.A repeated measures quasi-experimental design was employed on a sample of British adults (N = 41). Data were collected using pre- and post-intervention scores on the General Anxiety Disorder (GAD-7) and Warwick-Edinburgh Mental Wellbeing (WEMWBS) scales.Inferential analysis procedures consisting of multiple tests for within-subjects effects all showed significantly lower levels of anxiety and higher levels of mental wellbeing post-intervention.Whilst additional confirmatory and longitudinal research is needed, the results of this exploratory study tentatively indicate that creative arts-based “interventions” delivered through digital media may be effective in substantively reducing common symptoms of anxiety.

The endowment effect is a behavioral bias; postulating people demand more to part with an object they own than they would offer to acquire the same object owned by others. Recent experimental research, however, suggests that this effect applies to consumption goods rather than exchange goods. Given that housing is a mix of consumption and exchange goods, it presents a unique opportunity to examine whether the effect exists in the real world through a quasi-experiment. Based on a policy change that relaxed the resale constraints of shared ownership housing in Hong Kong, we found that more constrained homeowners were more likely to sell their homes compared to those with fewer constraints when granted the right to exchange, all other factors affecting liquidity being held constant. This marks the first field study revealing that the endowment effect diminishes when a good enhances its exchange nature, such as being given an exchange right. [ABSTRACT FROM AUTHOR]

ADHD is associated with an increased risk of injury. Causal evidence for effects of pharmacological treatment on injuries is scarce. We estimated effects of ADHD medication on injuries using variation in provider preference as an instrumental variable (IV). Using Norwegian registry data, we followed 8051 patients who were diagnosed with ADHD aged 5 to 18 between 2009 and 2011 and recorded their ADHD medication and injuries treated in emergency rooms and emergency wards up to 4 years after diagnosis. Persons with ADHD had an increased risk of injuries compared to the general population (RR 1.35; 95% CI: 1.30–1.39), with higher risk in females (RR 1.47; 95% CI: 1.38–1.56) than males (RR 1.23; 95% CI: 1.18–1.28). The between-clinics variation in provider preference for ADHD medication was large and had a considerable impact on patients' treatment status. There was no causal evidence for protective effects of pharmacological treatment on injuries overall for young individuals with ADHD characterized by milder or atypical symptoms. However, there was an apparent effect of pharmacological treatment over time on the risk of injuries treated at emergency wards in this patient group. [ABSTRACT FROM AUTHOR]

Background: Undergraduates' collective epistemic agency is critical for their productive collaborative inquiry and knowledge building (KB). However, fostering undergraduates' collective epistemic agency is challenging. Studies have demonstrated the potential of computer‐supported collaborative inquiry approaches, such as KB—the focus of this study, and reflective assessment to foster collective epistemic agency. Objectives: This study used a quasi‐experimental design to examine the impact of reflective assessment on undergraduates' collective epistemic agency and the mechanisms of this impact. Methods: An experimental class, comprising 40 undergraduates, engaged in KB inquiry enhanced by analytics‐assisted reflective assessment, while a comparison class, comprising 41 undergraduates, engaged in portfolio‐supported reflective assessment in KB inquiry. Classroom observations, audio recordings of group discussions and reflections, and student artefacts were collected in both conditions. Results and Conclusions: The experimental class demonstrated significantly higher levels of collective epistemic agency than the comparison class, as indicated by their collective knowledge advancement and epistemic and metacognitive actions. Qualitative thematic analysis revealed that reflective assessment enhanced the undergraduates' collective epistemic agency through their collective monitoring and regulation of inquiry and ideas, negotiation and synthesis of the community's ideas, conceptualization of collective theories and identification of collective inquiry trajectories with an internal reflective structure. Major Takeaways: Higher‐level metacognitive actions are critical for productive collaborative inquiry and higher‐level epistemic agency that does not often occur naturally and should be promoted by appropriate scaffolding strategies. Students need data from learning analytics and accompanying prompt sheets to help them develop the internal metacognitive structure for agency and learning. Lay Description: What is currently known about this topic?: Undergraduates' collective epistemic agency (CEA) is critical for productive KB.Analytics‐assisted reflective assessment (AARA) are promising in fostering CEA. What does this paper add?: AARA has positive influences on students' CEAAARA helps students develop CEA through the following mechanisms.AARA supports students' collective regulation and negotiation of collective ideas.AARA enhances conceptualization and deepening of collective trajectories with an internal reflective structure. Implications for practice/or policy: Higher‐level metacognitive actions are critical for collaborative inquiry and CEAAnalytics‐assisted RA can enhance students' higher‐level metacognitive actions.Students should be provided with learning data and appropriate scaffolding strategies.These data and strategies can develop students' internal metacognitive structure crucial for agency and learning.

Social work aspires to change social outcomes through policy and practice. Thus, researchers often use quantitative analysis to understand how social phenomena or policy and practice interventions change outcomes, but these causal questions cannot be answered using statistical association only. Directed acyclic graphs (DAGs), also called causal graphs, are a framework for representing assumptions about the causal relations between variables, imbuing statistical associations with causal meaning. This visual language may be more accessible than a math-based approach. We provide social work researchers with clear guidelines for using DAGs. First, we synthesize the current DAG literature and show how many statistical phenomena are represented in DAGs. Second, we describe an ordered process for building a DAG around a causal question about the impact of a treatment on an outcome. Third, we introduce a structured process called "clock and grid" for specifying the confounders that must be accounted for to estimate the unbiased causal effect. Throughout, we use working examples of social work evaluation scenarios to facilitate understanding of these concepts. We argue that DAGs represent an end-to-end conceptual framework for curating subject area knowledge that can advance social work research by informing design and analysis. [ABSTRACT FROM AUTHOR]

During the COVID-19 pandemic, many online lessons for emergency remote teaching (ERT) were recorded. However, little is known about how these recordings can be reused as resources for students’ active learning. This study aimed to design a post-video learning approach that uses recorded videos of lessons to remediate students’ learning losses associated with the pedagogical challenges of ERT. Two classes (54 students in total) with two teachers of general studies and mathematics in a Hong Kong primary school participated in a quasi-experimental study in which they used an approach integrating video selection, visualizations of classroom dialogues, a discussion forum, and quizzes for 10 weeks. After the intervention, the students’ mathematics knowledge had improved significantly relative to a comparison group, while the general studies class did not show significant changes. Eight students and two teachers were interviewed about their experiences with the post-video learning approach. The approach appeared to be a pedagogically meaningful way of engaging students in active learning activities and addressing the challenges raised by ERT by recycling recorded lessons. The results of this study also suggest that recorded lessons can be useful learning materials beyond tertiary education as they cater to younger learners’ needs in video-based learning by, for example, segmenting class videos, using visualization for easier viewing, and including discussion forums and quizzes for enhanced interaction. The design implications of using video segments and visualized representations of classroom interactions as learning materials and how to foster knowledge co-construction through forums and quizzes are also discussed.

Conversational agents (CAs) primarily adopt knowledge scaffolding (KS) or emotional scaffolding (ES) to intervene in learners’ knowledge gain and emotional experience in online learning. However, the ill-defined design for KS and ES, as well as insufficient understanding of their interactive effects on learning outcomes, have hindered the advancement of CAs in theory and practice. This study proposed systematic KS and ES design principles based on Zone of Proximal Development and growth mindset theories. We investigated their individual and combined impacts on knowledge gain and emotional experience. A quasi-experiment was conducted with 128 undergraduate students divided into four groups, corresponding to four distinct CAs: a non-scaffolding control group (CG), ES, KS, and Knowledge and Emotional Scaffolding (K&ES) CA. The results showed that K&ES-based CA had a significant impact on knowledge gain and emotional experience, with both being slightly improved compared to CG. Besides, KS-based CA had a positive effect on knowledge gain and emotional experience, while ES-based CA only slightly improved emotional experience compared to CG. The results validated the effectiveness of the proposed ES and KS design principles. The fine-grained analysis revealed a significant correlation between the achievement positive emotion and knowledge transfer, highlighting the importance of integrating KS and ES. In conclusion, this study offers valuable theoretical, methodological, and empirical insights for utilizing CAs to optimize online learning experiences.

As a fundamental logistics service, the express delivery (ED) industry provides production and consumption activities to maintain efficient supply chain operations. It plays an important role in promoting industrial development and maintaining daily life and consumption. This study examined the effects of COVID-19 on the ED industry using ED package delivery data from 31 provinces (autonomous regions and municipalities) in China. Using a difference-in-differences method, the COVID-19 outbreak was found to have a positive effect and epidemic prevention and control (EPC) policies were found to have negative effects on the development of the ED industry. In addition to EPC policies, the Chinese government has implemented other short-term economic interventions (SEI), such as the resumption of work and production (RWP), policies to balance economic growth, and epidemic prevention. This study divided the pandemic period into three stages to analyze the different impacts of EPC and SEI policy changes on the ED industry. The RWP policies adopted during the pandemic positively impacted the volume and income of packages delivered to the ED industry. The conclusions of this study are significant for the ED industry in addressing public health emergencies and for the Chinese government to formulate EPC and SEI policies during epidemic periods.

A burgeoning collaborative government-citizen public service delivery mode is hindered by insufficient policy mix credibility for boosting citizen participation. One reason is the unclear understanding of systematic pathways linking policy mix credibility and citizen participation. This article focuses on the relationship between policy mix credibility and citizen participation behavior based on the policy feedback theory. It also introduces citizen participation willingness as a mediator, and ICT tool functionality as moderators to further understand their boundary effects. Using a panel data from four follow-up surveys during the waste sorting policy pilot in Chongqing, China, and employing the difference-in-difference method, we found that policy mix credibility influences citizen participation behavior through citizen participation willingness. And the translation of willingness into actual participation action depends on policy resources represented by the ICT tool functionality. The findings solve the theoretical perplexity about the role of policy mix credibility in citizen participation in public service provision and provide new ideas for mobilizing it.

Families' education investment in their children is crucial for fostering and accumulating human capital among rural children in China. This study examines the impact of the Poverty Alleviation Relocation Program (PARP) on household education investment using panel data from a large-scale survey conducted in 16 counties across 8 provinces over three waves. Employing a staggered difference-in-differences (DID) method, we find a significant increase in average education investment per student in households following the PARP's implementation, supported by multiple robustness tests. Mechanism analysis reveals that the increase is primarily driven by a higher household income and lower medical expenses among relocated families. Heterogeneity analysis shows notable variations based on relocation attributes and household characteristics, with stronger effects particularly observed for dispersed relocation, scattered resettlement, and household heads with over 6 years of education or in good health. The impact is sustained and strengthens with longer durations of relocation. Our findings offer valuable insights for enhancing rural household education investment. [ABSTRACT FROM AUTHOR]

Results from previous research suggest that terrorist attacks lead to relatively short-term increases in trust in institutions. The explanation for this increase is known as the ‘rally effect’, whereby individuals respond to crises and threats with more positive support for political leaders and institutions. Even though the number of related natural experiments with survey data is increasing, these studies merely represent case studies of single incidents with limited external validity. To advance quasi-experimental research on the effects of terrorist attacks on institutional trust, we propose a new methodological approach by assessing all jihadist terrorist attacks resulting in at least one civilian death in a European country that take place during the fieldwork of the European Social Survey and combining the results of eight unique natural experiments in five different countries using meta-analytic and meta-regression techniques. The results of this ‘multi-site natural experiment’ indicate that support for the rally-hypothesis is mixed at best. While some attacks appear to significantly increase at least some measures of institutional trust (e.g., The Netherlands 2004, France 2015, Israel 2012), others seem to have no effect at all (e.g., Germany 2015, France 2018), or even substantially decrease trust in domestic political institutions (Russia 2012). Summary effects from multilevel meta-analyses are non-significant for any institutional trust outcome. These results are robust to a large number of robustness tests and alternative specifications. In comparison with previous research, it appears that a lot of the European evidence for the rally-hypothesis was based on ‘outlier’ case studies like the Charlie Hebdo attack in France, 2015. Accordingly, our results cast doubt on the unrestricted generalisability of rally effects after terrorist attacks to different geographic, political, social or historical contexts.

Research Summary: This paper describes Rainier Beach: A Beautiful Safe Place for Youth (ABSPY), a community‐led, place‐based, data‐driven initiative to improve community safety and reduce crime involving young people at hot spots in Seattle, Washington. The ABSPY model puts crime prevention into the hands of the community, compared to traditional problem‐solving approaches that may involve community stakeholders but are led by the police. We evaluated the initiative using a quasi‐experimental research design comparing the five hot spots in the Rainier Beach neighborhood, where ABSPY was implemented, to five similarly situated hot spots elsewhere in the city. We used 9 years of police calls for service and offense reports, from 2011 to 2019, to assess ABSPY's effects on crime and a five‐wave community survey conducted pre‐ and 4 years post‐implementation to examine community perceptions. Although there were no significant effects on calls for service or crime, ABSPY significantly improved community members' perceptions of serious crime and the police in the short and medium term. Policy Implications: Our results show positive changes in community perceptions that offer a foundation for relationship and capacity building in problem‐solving efforts. Although ABSPY is not associated with reductions in crime, our results suggest that even communities with entrenched crime problems can leverage this capacity to reduce crime in the longer term. Community coalitions also offer some benefits relative to police‐led efforts, such as shared culture and values; stability; and consistency. However, community coalitions must build capacity for action as well as community engagement, and consider if and how the police should be involved, ensuring that the specific expertise of each coalition member is leveraged. Furthermore, our study highlights the importance of identifying measures of crime that are not affected by increased trust and collaboration between the police and the community.

States have adopted a variety of policies to encourage universities to expand research production, with the hope of supporting economic growth and competitiveness. This paper considers whether a state-level initiative succeeded in influencing university-based research outputs among regional public universities. We test whether the Texas Research Incentive Program increased research production at a set of state universities as measured by total research spending, federally-funded research spending, the number of scholarly publications, and the share of publications published in high impact factor journals. Using a novel dataset and difference-in-differences analytic strategy, we found that TRIP adoption was associated with a 19%-25% increase in research expenditures at emerging research universities in Texas relative to a matched set of comparable universities. However, TRIP did not influence federally-funded research expenditures or journal publication outputs. We also show that federally-funded research expenditures influence publication outputs — both in amount and quality — and that number of full-time faculty influences both federal research expenditures and publication outputs. We discuss contributions to the literature on regional public universities, loose coupling, and research production, as well as implications for policy. [ABSTRACT FROM AUTHOR]

Opinion polarisation in social media has recently become a significant issue. The existing literature mainly attributes polarisation to online friends' informational social influence, that is, users are more likely to interact with others with similar opinions, which leads to the echo chamber effect. However, the impact of social interaction on individual polarisation may also result from normative social influence, which varies with social settings on the platform. In this paper, we leverage a quasi‐experiment to investigate the normative social influence of online friends on focal users' review polarity. We use fixed effects and difference‐in‐differences approaches, along with propensity score matching, to address the potential endogeneity in users' friend function adoption decisions. Our results indicate that adopting the friend function leads users to post less extreme ratings. We further separate the reviews into positive and negative, finding that the reduction in the review polarity for positive reviews is more prominent than for negative ones. Regarding user heterogeneity, our causal forest analysis uncovers that users with a higher engagement level on the platform are less affected by adopting the friend function than those with less engagement. Our study has clear implications for managers and platform designers, highlighting the importance of social function design in reducing social media induced polarisation. [ABSTRACT FROM AUTHOR]

We shed light on assessing product quality in blind tastings and their potential (gender) biases. We study how phonetic traits of grape varieties suggest product attributes in the context of professional reviews. This study aims to close this research gap and analyze how product variety and phonetic name traits affect expert ratings. We obtained data on 18,609 wines and their ratings from Wine Enthusiast Magazine between 1997 and 2016, yielding a sample of 31,058 observations. We suppose that the gender of the taster needs to be considered to understand what affects tastings and ratings, as women and men might be attracted differently to masculine or feminine names. This study shows that masculine names receive higher evaluations than feminine ones. This phonetic gender gap is driven by lower ratings for white wines by female reviewers and lower ratings for red wines by male reviewers. In addition, white wines are rated lower overall by both men and women. [ABSTRACT FROM AUTHOR]

Criminality rates are higher among persons with attention-deficit/hyperactivity disorder (ADHD), and evidence that medication reduces crime is limited. Medication rates between clinics vary widely even within universal health care systems, partly because of providers' treatment preferences. We used this variation to estimate causal effects of pharmacological treatment of ADHD on 4-year criminal outcomes. We used Norwegian population-level registry data to identify all unique patients aged 10 to 18 years diagnosed with ADHD between 2009 and 2011 (n = 5,624), their use of ADHD medication, and subsequent criminal charges. An instrumental variable design, exploiting variation in provider preference for ADHD medication between clinics, was used to identify causal effects of ADHD medication on crime among patients on the margin of treatment, that is, patients who receive treatment because of their provider's preference. Criminality was higher in patients with ADHD relative to the general population. Medication preference varied between clinics and strongly affected patients' treatment. Instrumental variable analyses supported a protective effect of pharmacological treatment on violence-related and public-order−related charges with numbers needed to treat of 14 and 8, respectively. There was no evidence for effects on drug-, traffic-, sexual-, or property-related charges. This is the first study to demonstrate causal effects of pharmacological treatment of ADHD on some types of crimes in a population-based natural experiment. Pharmacological treatment of ADHD reduced crime related to impulsive-reactive behavior in patients with ADHD on the margin of treatment. No effects were found on crimes requiring criminal intent, conspiracy, and planning. The ADHD controversy project: Long-term effects of ADHD medication; https://www.isrctn.com/ ; 11891971.

In 2019, New York State passed bail reform legislation that limited the use of money bail and expanded pretrial release. The bail reform law took effect on January 1, 2020. We evaluated the effect of this law on crime rates in New York State. Interrupted time series analyses (ITSA) were used to examine whether the bail reform was significantly associated with a crime increase. When a significant association was detected, we examined whether this relationship was causal. The causal relationship was tested using synthetic control methods (SCM). We found that the rates of murder, larceny, and motor vehicle theft increased after the bail reform. We then employed SCM to create a comparison group to control for potential confounders like the pandemic. By comparing New York State with its synthetic control, we found the increases in the murder rate, larceny rate, and motor vehicle theft rate were not statistically significant. Our findings suggest that the effect of bail reform on crime rate increases is negligible. [ABSTRACT FROM AUTHOR]
