Time for Iran to Make a No-enrichment Nuclear Deal
The time has come for Iran’s leaders to reconsider their past intransigent, deceptive posture and instead pursue a nuclear power program that will benefit the Iranian people, write Abbas Milani and Siegfried Hecker.
Is it possible to reduce crime without exacerbating adversarial relationships between police and citizens? Community policing is a celebrated reform with that aim, which is now adopted on six continents. However, the evidence base is limited, studying reform components in isolation in a limited set of countries, and remaining largely silent on citizen-police trust. We designed six field experiments with Global South police agencies to study locally designed models of community policing using coordinated measures of crime and the attitudes and behaviors of citizens and police. In a preregistered meta-analysis, we found that these interventions led to mixed implementation, largely failed to improve citizen-police relations, and did not reduce crime. Societies may need to implement structural changes first for incremental police reforms such as community policing to succeed.

Research continues to highlight the central relationship between caregivers’ mental health and their children’s development. This study examined the relation between primary caregivers’ mental health and school-aged children’s outcomes, including student mental health, resilience, and academic performance, in rural China. Using cross-sectional data from economically poor areas in the Gansu province, 2989 students (mean age = 11.51, 53.33% male, 46.67% female) and their primary caregivers (74.2% female) completed the 21-item, self-report Depression Anxiety Stress Scale. Students also completed the 25-item Connor-Davidson Resilience Scale and a standardized math test. The results indicated a high prevalence of caregiver depression (31%), stress (39%), and anxiety (24%). Characteristics that were significantly correlated with caregiver mental health issues included being a grandparent, having a low socioeconomic status and low education level, and living in a household with at least one migrant worker. Apart from caregiver stress and student resilience, caregiver mental health issues were negatively correlated with all student outcomes, including student mental health, resilience, and academic performance. Although additional empirical research is needed to investigate the associations between caregiver mental health and student outcomes, our results suggest that rural communities could benefit greatly from programs focused on improving the mental health of caregivers and this, in turn, may have a positive impact on student outcomes.
Can differences in beliefs about politics, particularly the benefits of war and peace, move markets? During the Siege of Paris by the Prussian army (1870-71) and its aftermath, we document that the price of the French 3% sovereign bond (rente) differed persistently between the Bourse in Paris and elsewhere, despite being one of the most widely held and actively traded financial assets in continental Europe. Further, these differences were large, reaching the equivalent of almost 1% of French GDP in overall value. We show these differences manifested themselves during the period of limited arbitrage induced by the Siege and persisted until the terms of peace were revealed. As long as French military resistance continued, the rente price was higher in Paris than the outside markets, but when the parties ceased fire and started negotiating peace terms this pattern was reversed. Further, while the price responded more to war events in Paris, the price responded more to peace events elsewhere. These specific patterns are difficult to reconcile with other potential mechanisms, including differential information sets, need for liquidity, or relative market thickness. Instead, we argue, these results are consistent with prices reflecting the updating of different prevailing political beliefs that existed in Paris and elsewhere about the benefits of war and peace.

Background: Maternal mental health problems play an important role in infant well-being. Although western countries have extensively studied the associations between maternal mental disorders, hygiene practices and infant health, little is known in developing settings. This study investigates the correlations between postnatal mental health problems, hand washing practices and infant illness in rural western China. Methods: A total of 720 mothers of infants aged 0–6 months from four poor counties in rural western China were included in the survey. Mental health symptoms were assessed using the Depression, Anxiety, and Stress Scale-21 (DASS-21). Questions about infant illness and hand washing practices followed evaluative surveys from prior studies. Adjusted ordinary least squares regressions were used to examine correlations between postnatal mental health (depression, anxiety, and stress) symptoms, hand washing practices, and infant illness outcomes. Results: Maternal depression, anxiety and stress symptoms were significantly associated with reduced hand washing overall and less frequent hand washing after cleaning the infant's bottom. Mental health symptoms were also associated with a higher probability of infants showing two or more illness symptoms and visiting a doctor for illness symptoms. Individual hand washing practices were not significantly associated with infant illness; however, a composite measure of hand washing practices was significantly associated with reduced probability of infant illness. Conclusion: Postnatal mental health problems are prevalent in rural China and significantly associated with infant illness. Policy makers and practitioners should investigate possible interventions to improve maternal and infant well-being.
A randomized trial of community-level mask promotion in rural Bangladesh during COVID-19 shows that the intervention increased mask-use and reduced symptomatic SARS-CoV-2 infections.
We present evidence from a randomized experiment testing the impacts of a six-month early childhood home-visiting program on child outcomes at school entry. Two and a half years after completion of the program, we find persistent effects on child working memory - a key skill of executive functioning that plays a central role in children's development of cognitive and socio-emotional skills. We also find that the program had persistent effects on parental time investments and preschool enrollment decisions. Children were enrolled earlier and in higher quality preschools, the latter reflecting a shift in preferences over preschool attributes toward quality. Our findings imply an important role for the availability of high-quality subsequent schooling in sustaining the impacts of early intervention programs.
This Article reframes transitional justice as communication. It argues that the impact of truth and reconciliation commissions (TRCs) and international criminal tribunals (ICTs) on countries where human rights violations occurred depends largely on these institutions changing what those countries’ citizens and elites know and believe. More precisely: most of the ways TRCs and ICTs could advance their goals—such as reconciliation and deterrence—require informing these domestic audiences about the institutions’ activities, methods, and findings, and persuading them to accept the institutions’ conclusions. Communication-specific activities, such as public outreach and media relations, are essential. Yet shaping elite and popular knowledge and opinion are not mere add-ons to what some see as TRCs’ and ICTs’ “core” work: investigating human rights violations, holding hearings, writing reports, and indicting and trying perpetrators. Rather, the imperative of influencing local people must shape how these institutions conduct those activities and sometimes even what conclusions they reach. Unfortunately, TRC commissioners, ICT judges and prosecutors, and their staff, along with transitional justice scholars, have underestimated the importance of influencing domestic audiences for advancing TRCs’ and ICTs’ goals. As a result, the institutions have devoted too little attention and resources to communication.
The Article also provides a typology of the activities and occasions through which TRCs and ICTs can influence domestic audiences. It offers examples of effective and ineffective practice from five international criminal tribunals, such as the International Criminal Court and Special Court for Sierra Leone, and over a dozen truth commissions, such as South Africa's Truth and Reconciliation Commission. Where evidence permits, it assesses individual institutions’ performance. Finally, the Article analyzes the most important challenges that TRCs and ICTs encounter in communicating with domestic audiences.
High resolution crop type maps are an important tool for improving food security, and remote sensing is increasingly used to create such maps in regions that possess ground truth labels for model training. However, these labels are absent in many regions, and models trained in other regions on typical satellite features, such as those from optical sensors, often exhibit low performance when transferred. Here we explore the use of NASA's Global Ecosystem Dynamics Investigation (GEDI) spaceborne lidar instrument, combined with Sentinel-2 optical data, for crop type mapping. Using data from three major cropped regions (in China, France, and the United States) we first demonstrate that GEDI energy profiles are capable of reliably distinguishing maize, a crop typically above 2m in height, from crops like rice and soybean that are shorter. We further show that these GEDI profiles provide much more invariant features across geographies compared to spectral and phenological features detected by passive optical sensors. GEDI is able to distinguish maize from other crops within each region with accuracies higher than 84\%, and able to transfer across regions with accuracies higher than 82\% compared to 64\% for transfer of optical features. Finally, we show that GEDI profiles can be used to generate training labels for models based on optical imagery from Sentinel-2, thereby enabling the creation of 10m wall-to-wall maps of tall versus short crops in label-scarce regions. As maize is the second most widely grown crop in the world and often the only tall crop grown within a landscape, we conclude that GEDI offers great promise for improving global crop type maps.
