RESUMEN

Enhancing vaccine uptake is a critical public health challenge1. Overcoming vaccine hesitancy2,3 and failure to follow through on vaccination intentions3 requires effective communication strategies3,4. Here we present two sequential randomized controlled trials to test the effect of behavioural interventions on the uptake of COVID-19 vaccines. We designed text-based reminders that make vaccination salient and easy, and delivered them to participants drawn from a healthcare system one day (first randomized controlled trial) (n = 93,354 participants; clinicaltrials number NCT04800965) and eight days (second randomized controlled trial) (n = 67,092 individuals; clinicaltrials number NCT04801524) after they received a notification of vaccine eligibility. The first reminder boosted appointment and vaccination rates within the healthcare system by 6.07 (84%) and 3.57 (26%) percentage points, respectively; the second reminder increased those outcomes by 1.65 and 1.06 percentage points, respectively. The first reminder had a greater effect when it was designed to make participants feel ownership of the vaccine dose. However, we found no evidence that combining the first reminder with a video-based information intervention designed to address vaccine hesitancy heightened its effect. We performed online studies (n = 3,181 participants) to examine vaccination intentions, which revealed patterns that diverged from those of the first randomized controlled trial; this underscores the importance of pilot-testing interventions in the field. Our findings inform the design of behavioural nudges for promoting health decisions5, and highlight the value of making vaccination easy and inducing feelings of ownership over vaccines.

RESUMEN

Over 45,000 gun deaths occur annually in the United States, a country with more than 100 million gun owners and more than 350 million guns. Nevertheless, passing legislation to reduce gun violence is difficult because the issue is intensely polarized. Polls asking about general gun policies (e.g., AR-15 restrictions) demonstrate that, at least in the abstract, Americans disagree vehemently about whether civilians should be able to keep and bear arms. It is possible, however, that a hidden consensus exists in America, which has thus far escaped attention-specifically, that when the focus is on their immediate environments and daily lives, even traditionally pro-gun groups may exhibit aversion to certain types of gun ownership and storage practices. To test this, we conducted two preregistered survey experiments with a large national sample. The first was a conjoint analysis where respondents chose between neighbors (n = 33,596 choices) who randomly varied on seven attributes, including gun ownership (none, pistol, AR-15). No group of respondents, not even traditionally pro-gun groups (e.g., Republicans), exhibited a significant preference for living near gun owners, and every group was averse to AR-15-owning neighbors. The second experiment, per debates about safe-storage laws, was a picture-based factorial vignette that randomized a neighbor's gun storage practices (n = 2,098). Every group of respondents was averse to interacting with a neighbor who stored guns outside of a locked safe. Our findings demonstrate that there is widespread agreement that certain types of gun ownership and storage practices are undesirable for communities.

RESUMEN

Using millions of observations compiled from the public administrative data of Taiwan, we find a surprising gender inequity in terms of real estate: Men own more land than women, and the annual rate of return (ROR) of men's land outperform women's by almost 1% per year. The latter finding of gender-based ROR difference is in sharp contrast to prior evidence that women outperform men in security investment, and also suggests a quantity-and-quality double jeopardy in female land ownership which, given the heavy weight of real estate in individual wealth, has important implications for wealth inequality among men and women. Our statistical analyses suggest that such a gender-based difference in land ROR cannot be attributed to individual-level factors such as liquidity preferences, risk attitudes, investment experience, and behavioral biases, as described in the literature. Rather, we hypothesize parental gender bias-a phenomenon that is still prevalent today-to be the key macrolevel factor. To test our hypothesis, we partition our observations into two groups: an experimental group in which parents can exercise gender discretion, and a control group in which parents cannot exercise such discretion. Our empirical evidence shows that the gender difference with respect to land ROR only exists in the experimental group. For many societies with long-lasting patriarchal traditions, our analysis provides a perspective to help explain gender differences in wealth distribution and social mobility.

RESUMEN

Forests serve a crucial role in our fight against climate change. Secondary forests provide important potential for conservation of biodiversity and climate change mitigation. In this paper, we explore whether collective property rights in the form of indigenous territories (ITs) lead to higher rates of secondary forest growth in previously deforested areas. We exploit the timing of granting of property rights, the geographic boundaries of ITs and two different methods, regression discontinuity design and difference-in-difference, to recover causal estimates. We find strong evidence that indigenous territories with secure tenure not only reduce deforestation inside their lands but also lead to higher secondary forest growth on previously deforested areas. After receiving full property rights, land inside ITs displayed higher secondary forest growth than land outside ITs, with an estimated effect of 5% using our main RDD specification, and 2.21% using our difference-in-difference research design. Furthermore, we estimate that the average age of secondary forests was 2.2 y older inside ITs with secure tenure using our main RDD specification, and 2.8 y older when using our difference-in-difference research design. Together, these findings provide evidence for the role that collective property rights can play in the push to restore forest ecosystems.

RESUMEN

The sense of body ownership (i.e. the feeling that our body or its parts belong to us) plays a key role in bodily self-consciousness and is believed to stem from multisensory integration. Experimental paradigms such as the rubber hand illusion have been developed to allow the controlled manipulation of body ownership in laboratory settings, providing effective tools for investigating malleability in the sense of body ownership and the boundaries that distinguish self from other. Neuroimaging studies of body ownership converge on the involvement of several cortical regions, including the premotor cortex and posterior parietal cortex. However, relatively less attention has been paid to subcortical structures that may also contribute to body ownership perception, such as the cerebellum and putamen. Here, on the basis of neuroimaging and neuropsychological observations, we provide an overview of relevant subcortical regions and consider their potential role in generating and maintaining a sense of ownership over the body. We also suggest novel avenues for future research targeting the role of subcortical regions in making sense of the body as our own.

RESUMEN

Body ownership and the sense of agency are two central aspects of bodily self-consciousness. While multiple neuroimaging studies have investigated the neural correlates of body ownership and agency separately, few studies have investigated the relationship between these two aspects during voluntary movement when such experiences naturally combine. By eliciting the moving rubber hand illusion with active or passive finger movements during functional magnetic resonance imaging, we isolated activations reflecting the sense of body ownership and agency, respectively, as well as their interaction, and assessed their overlap and anatomic segregation. We found that perceived hand ownership was associated with activity in premotor, posterior parietal, and cerebellar regions, whereas the sense of agency over the movements of the hand was related to activity in the dorsal premotor cortex and superior temporal cortex. Moreover, one section of the dorsal premotor cortex showed overlapping activity for ownership and agency, and somatosensory cortical activity reflected the interaction of ownership and agency with higher activity when both agency and ownership were experienced. We further found that activations previously attributed to agency in the left insular cortex and right temporoparietal junction reflected the synchrony or asynchrony of visuoproprioceptive stimuli rather than agency. Collectively, these results reveal the neural bases of agency and ownership during voluntary movement. Although the neural representations of these two experiences are largely distinct, there are interactions and functional neuroanatomical overlap during their combination, which has bearing on theories on bodily self-consciousness.SIGNIFICANCE STATEMENT How does the brain generate the sense of being in control of bodily movement (agency) and the sense that body parts belong to one's body (body ownership)? Using fMRI and a bodily illusion triggered by movement, we found that agency is associated with activity in premotor cortex and temporal cortex, and body ownership with activity in premotor, posterior parietal, and cerebellar regions. The activations reflecting the two sensations were largely distinct, but there was overlap in premotor cortex and an interaction in somatosensory cortex. These findings advance our understanding of the neural bases of and interplay between agency and body ownership during voluntary movement, which has implications for the development of advanced controllable prosthetic limbs that feel like real limbs.

RESUMEN

BACKGROUND: Urologists practicing in single-specialty groups with ownership in radiation vaults are more likely to treat men with prostate cancer. The effect of divestment of vault ownership on treatment patterns is unclear. METHODS: A 20% sample of national Medicare claims was used to perform a retrospective cohort study of men with prostate cancer diagnosed between 2010 and 2019. Urology practices were categorized by radiation vault ownership as nonowners, continuous owners, and divested owners. The primary outcome was use of local treatment, and the secondary outcome was use of intensity-modulated radiation therapy (IMRT). A difference-in-differences framework was used to measure the effect of divestment on outcomes compared to continuous owners. Subgroup analyses assessed outcomes by noncancer mortality risk (high [>50%] vs. low [≤50%]). RESULTS: Among 72 urology practices that owned radiation vaults, six divested during the study. Divestment led to a decrease in treatment compared with those managed at continuously owning practices (difference-in-differences estimate, -13%; p = .03). The use of IMRT decreased, but this was not statistically significant (difference-in-differences estimate, -10%; p = .13). In men with a high noncancer mortality risk, treatment (difference-in-differences estimate, -28%; p < .001) and use of IMRT (difference-in-differences estimate, -27%; p < .001) decreased after divestment. CONCLUSIONS: Urology group divestment from radiation vault ownership led to a decrease in prostate cancer treatment. This decrease was most pronounced in men who had a high noncancer mortality risk. This has important implications for health care reform by suggesting that payment programs that encourage constraints on utilization, when appropriate, may be effective in reducing overtreatment.

RESUMEN

Tumor mutation profiling (MP) is often conducted on tissue from biopsies conducted for clinical purposes (diagnostic tissue). We aimed to explore the views of patients with cancer on who should own tumor biopsy tissue, pay for its storage, and decide on its future use; and determine their attitudes to and predictors of undergoing additional biopsies if required for research purposes. In this mixed methods, cross-sectional study, patients with advanced solid cancers enrolled in the Molecular Screening and Therapeutics Program (n = 397) completed a questionnaire prior to undergoing MP (n = 356/397). A subset (n = 23) also completed a qualitative interview. Fifty percent of participants believed they and/or relatives should own and control access to diagnostic tissue. Most (65.5%) believed the government should pay for tissue preparation. Qualitative themes included (1) custodianship of diagnostic tissue, (2) changing value of tissue across time and between cultures, (3) equity regarding payment, and (4) cost-benefit considerations in deciding on additional biopsies. Policy and regulation should consider patient perspectives. Extension of publicly funded health care to include tissue retrieval for clinical trials should be considered.

RESUMEN

OBJECTIVE: To determine if firearm ownership is positively related to elevated child lead levels at a state-level, even when accounting for other sources of lead. STUDY DESIGN: For this cross-sectional ecological study, we investigated whether household firearm ownership rates (a proxy for firearm-related lead exposure) was associated with the prevalence of elevated child blood lead levels in 44 US States between 2012 and 2018. To account for potential confounding, we adjusted for other known lead exposures, poverty rate, population density, race, and calendar year. To address missing data, we used multiple imputation by chained equations. RESULTS: Prevalence of elevated child blood lead positively correlated with household firearm ownership and established predictors of lead exposure. In fully adjusted negative binomial regression models, child blood lead was positively associated with household firearm ownership and older housing; each IQR (14%) increase in household firearm ownership rate was associated with a 41% higher prevalence of childhood elevated blood lead (prevalence ratio: 1.41, 95% CI: 1.11-1.79). CONCLUSION: These data provide state-level evidence that firearms may be an important source of child lead exposure. More research is needed to substantiate this relationship and identify modifiable pathways of exposure at the individual level.

RESUMEN

BACKGROUND: Recent studies document the rising prevalence of common ownership by institutional investors in specific industries. Those investors offer products, such as mutual and index funds, to trade securities on behalf of others and often own shares of multiple firms in the same industry to diversify portfolios. However, at present, few studies focus on common ownership trends in health care. OBJECTIVES: This paper examines institutional investors' common ownership in the major insurers offering plans in the Medicare Part D stand-alone prescription drug plan (PDP) market between 2013 and 2020. RESEARCH DESIGN: Using data from the Securities and Exchange Commission (SEC) database and the Center for Research in Securities Prices, we compute the percentages of outstanding shares of each insurer owned by institutional investors. Data visualization and network analysis are employed to assess the trends in common ownership among major insurers. RESULTS: We document a high prevalence of and substantial increase in shared institutional investors in the PDP market. From 2013 to 2020, the degree of common ownership increased by 7% on average, and the common ownership network became more connected. Common ownership also varies across the 34 PDP regions depending on their reliance on listed insurers, that are traded in the stock exchange, offering stand-alone PDPs. CONCLUSIONS: High and rising common ownership in the Medicare Part D PDP market raises policy questions about potential effects on plan offerings, premiums, and quality for consumers.

RESUMEN

Our understanding of ownership influences how we interact with objects and with each other. Here, we studied people's intuitions about ownership transfer using a set of simple, parametrically varied events. We found that people (N = 120 U.S. adults) had similar intuitions about ownership for some events but sharply opposing intuitions for others (Experiment 1). People (N = 120 U.S. adults) were unaware of these conflicts and overestimated ownership consensus (Experiment 2). Moreover, differences in people's ownership intuitions predicted their intuitions about the acceptability of using, altering, controlling, and destroying the owned object (N = 130 U.S. adults; Experiment 3), even when ownership was not explicitly mentioned (N = 130 U.S. adults; Experiment 4). Subject-level analyses suggest that these disagreements reflect at least two underlying intuitive theories, one in which intentions are central to ownership and another in which physical possession is prioritized.

RESUMEN

Understanding how initiatives to support Black-owned businesses are received, and why, has important social and economic implications. To address this, we designed three experiments to investigate the role of antiegalitarian versus egalitarian ideologies among White American adults. In Study 1 (N = 199), antiegalitarianism (vs. egalitarianism) predicted viewing initiatives supporting a Black-owned business as less fair, but only when the business was competing with other (presumably White-owned) businesses. In Study 2 (N = 801), antiegalitarianism predicted applying survival-of-the-fittest market beliefs, particularly to Black-owned businesses. Antiegalitarianism also predicted viewing initiatives supporting Black-owned businesses as less fair than initiatives that targeted other (presumably White-owned) businesses, especially for tangible (vs. symbolic) support that directly impacts the success of a business. In Study 3 (N = 590), antiegalitarianism predicted rejecting a program investing in Black-owned businesses. These insights demonstrate how antiegalitarian ideology can have the effect of maintaining race-based inequality, hindering programs designed to reduce that inequality.

RESUMEN

BACKGROUND: Insecticide-treated nets (ITNs) are pivotal tools for malaria prevention in endemic regions like Ghana. Understanding the protective factors and barriers influencing ITN ownership and usage is crucial for designing effective interventions. A scoping review was conducted to identify studies exploring protective factors and barriers related to ITN ownership and usage. METHODS: This review followed the guidelines by Askey and O'Malley. Search was done in four major databases including PubMed, Science Direct, PubMed CENTRAL, and JSTOR. Additional searches were done in Google Scholar and Google. Peer-reviewed and grey literature were included. RESULTS: A total of 24 papers met the eligibility criteria and were included in the review. Included studies found regional disparities in ITN ownership and usage. Furthermore, included studies reported ownership rates between 97.8 and 28% and usage rates between 94 and 20%. Protective factors facilitating ITN ownership were marital status, higher educational attainment, higher income levels, and being aged 25 years or older. In contrast, the factors for its use included community-level campaigns advocating for ITN use and awareness, individuals with secondary education or higher and those residing in urban areas. Missed opportunities in free distribution exercises and the unavailability of subsidized ITNs at health facilities were barriers to ownership. CONCLUSION: Understanding and addressing protective factors and barriers influencing ITN ownership and usage are crucial for enhancing malaria prevention strategies and achieving sustainable progress in combating malaria in endemic areas. Collaborative and evidence-based interventions are essential for addressing these challenges effectively.

RESUMEN

BACKGROUND: Malaria poses a substantial public health threat in Myanmar, indicating the need for rigorous efforts to achieve elimination of the disease nationwide by 2030. The use of insecticide-treated nets (ITNs) forms part of a pivotal strategy for preventing transmission. This study explored the ownership and use of ITNs in Myanmar and identified factors associated with non-use of ITNs. METHODS: Household datasets from the 2015-2016 Myanmar Demographic and Health Survey were utilised, which encompassed all household members except children under the age of five. Descriptive statistics and inferential tests, including simple and multiple logistics regression models and Pearson correlations, were employed for analysis. All analyses, taking the two-stage stratified cluster sampling design into account, used weighting factors and the "svyset" command in STATA. The ownership and use of bed nets were also visualised in QGIS maps. RESULTS: Among the 46,507 participants, 22.3% (95% CI 20.0%, 24.5%) had access to ITNs, with only 15.3% (95% CI 13.7, 17.1%) sleeping under an ITN the night before the survey. Factors associated with the non-use of ITNs included age category (15-34 years-aOR: 1.17, 95% CI 1.01, 1.30; 50+ years-aOR: 1.19, 95% CI 1.06, 1.33), location (delta or lowland-aOR: 5.39, 95% CI 3.94, 7.38; hills-aOR: 1.80, 95% CI 1.20, 2.71; plains-aOR: 3.89, 95% CI 2.51, 6.03), urban residency (aOR: 1.63, 95% CI 1.22, 2.17), and wealth quintile (third-aOR: 1.38, 95% CI 1.08, 1.75; fourth-aOR: 1.65, 95% CI 1.23, 2.23; fifth-aOR: 1.47, 95% CI 1.02, 2.13). A coherent distribution of the ownership and use of ITNs was seen across all states/regions, and a strong correlation existed between the ownership and use of ITNs (r: 0.9795, 95% CI 0.9377, 0.9933, alpha < 0.001). CONCLUSIONS: This study identified relatively low percentages of ITN ownership and use, indicating the need to increase the distribution of ITNs to achieve the target of at least one ITN per every two people. Strengthening the use of ITNs requires targeted health promotion interventions, especially among relatively affluent individuals residing in delta or lowland areas, hills, and plains.

RESUMEN

INTRODUCTION: Regular physical activity is important for children's physical and mental health, yet many children do not achieve recommended amounts of physical activity. Dog ownership has been associated with increased physical activity in children, however, there have been no longitudinal studies examining this relationship. This study used data from the Play Spaces and Environments for Children's Physical Activity (PLAYCE) cohort study to examine the longitudinal effects of dog ownership status on children's movement behaviours. METHODS: Change in dog ownership from preschool (wave 1, age 2-5) to fulltime school (wave 2, age 5-7) was used as a natural experiment with four distinct dog ownership groups: continuing non-dog owners (n = 307), continuing dog owners (n = 204), dog acquired (n = 58), and dog loss (n = 31; total n = 600). Daily movement behaviours, including physical activity, sedentary time, sleep, and screen time, were measured using accelerometry and parent-report surveys. Differences between groups over time and by sex were tested using linear mixed effects regression models. RESULTS: Girls who acquired a dog increased their light intensity activities and games by 52.0 min/day (95%CI 7.9, 96.0) and girls who lost a dog decreased their light intensity activities and games by 62.1 min/day (95%CI -119.3, -4.9) compared to no change among non-dog owners. Girls and boys who acquired a dog increased their unstructured physical activity by 6.8 (95%CI 3.2, 10.3) and 7.1 (95%CI 3.9, 10.3) occasions/week, compared to no changes among non-dog owners. Girls and boys who lost a dog reduced their unstructured physical activity by 10.2 (95%CI -15.0, -5.3) and 7.7 (95%CI -12.0, -3.5) occasions/week. Girls who lost a dog decreased their total physical activity by 46.3 min/day (95%CI -107.5, 14.8) compared to no change among non-dog owners. Continuing dog ownership was typically not associated with movement behaviours. Dog ownership group was not associated with changes in sleep and had mixed associations with screen time. CONCLUSION: The positive influence of dog ownership on children's physical activity begins in early childhood and differs by child sex. Further research should examine the specific contributions dog-facilitated physical activity makes to children's overall physical activity, including the intensity and duration of dog walking and play.

RESUMEN

INTRODUCTION: Firearms now represent the leading cause of death in U.S. children. Therefore, this study aimed to determine if state-level rates of gun ownership, guns in circulation, and strictness of firearm-related laws are related to firearm-related mortality among both juveniles and overall populations. MATERIALS AND METHODS: State firearm mortality rates among the juvenile and overall populations were obtained from 2010 to 2020. The number of weapons registered with the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) and federal firearms licensees for each state were also recorded. Giffords Law Center Scorecard Rankings, a relative measure of the restrictiveness of each state's gun laws, were also collected. Unadjusted linear regressions modeled the relationships between firearm-associated mortality and ATF-registered weapons, federal firearm licensees, Giffords Center rankings, and gun ownership rates. Multivariable (adjusted) analyses were performed to control for poverty, unemployment, and poor mental health. RESULTS: Unadjusted analyses demonstrated that higher gun ownership rates and more lenient gun laws were associated with increased firearm-associated mortality among juveniles. Similarly, these measures as well as increased ATF-registered weapons and ATF federal firearm licensees were associated with increased firearm mortality in the overall population. In the adjusted analyses, more ATF-registered weapons, more ATF federal firearm licensees, higher gun ownership rates, and more lenient firearm laws were associated with increased firearm-related mortality in the overall population, while increased gun ownership and higher Giffords Center rankings were associated with increased firearm-associated mortality in the pediatric population. CONCLUSIONS: To reduce the toll of gun violence in the United States, policymakers should focus on implementing more restrictive firearm laws and reducing the prevalence of guns in their communities.

RESUMEN

INTRODUCTION: Firearm-related suicides among children present a significant public health concern and a tragic loss of young lives. This study explores the relationship between firearm-related suicides, gun ownership, and state-specific gun laws. METHODS: This retrospective cohort study collected data from the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research on children under 18 who died by firearm-related suicides between 2009 and 2016 in all 50 states and D.C. It also utilized data from the RAND State-Level Estimates of Household Firearm Ownership. The study focused on the rate of child firearm suicide deaths per 100,000 individuals. The key variable of interest was the percentage of guns owned per household in each state. Univariable analysis was conducted to examine the association between individual gun laws and child firearm suicide mortalities, while multivariable regression, adjusting for household gun ownership and significant firearm legislation, was employed to assess connection to child firearm suicide mortality. RESULTS: From 2009 to 2016, 3903 children died from firearm-related suicides in the United States. In our analysis, 15 out of 44 firearm laws were found to be associated with reducing the rates of firearm suicides among children (P < 0.05). However, multivariable regression showed that higher state gun ownership rates were the primary predictor of increased child fatalities from firearms, with children in such states being 325% more likely to die when analyzing handgun laws and 337% more likely when analyzing long gun laws, as indicated by coefficients of 4.25 and 4.37, respectively. No state laws alone notably improved death rates. CONCLUSIONS: Gun ownership has a stronger association with child suicide rates than state-specific gun laws. Given the weight of gun ownership, future research should prioritize comprehensive public health initiatives to prevent child firearm-related suicides.

RESUMEN

Peripersonal space (PPS), as opposed to extrapersonal space (EPS), refers to the area surrounding the body within which individuals interact with objects or conspecifics. However, objects in PPS can belong to oneself or to others, which was found to influence how these objects are encoded. We analyzed the performances of motor responses in a reachability judgment task concerning self-owned and other-owned objects (cups) presented in PPS or EPS. EMG activities were recorded on the thumbs (flexor pollicis brevis) to detect correct and erroneous motor activations. Behavioral data showed that motor responses were shorter and longer for self-owned cups compared to other-owned cups in PPS and EPS, respectively. Ten percent of trials showed initial response errors, which were higher in the EPS for self-owned cups and in the PPS for other-owned cups. Eighty-two percent of these errors were corrected online, with corrections being more efficient for self-owned cups in the PPS. Overall, the data revealed that reachability judgments were faster and more accurate in the PPS, with more efficient inhibition processes in the presence of motor errors. Motor selection and correction are thus modulated by the social context of object ownership, highlighting the specific role of the PPS in encoding self-relevant objects for action.

RESUMEN

Because global anthropogenic activities cause vast biodiversity loss, human dimensions research is essential to forming management plans applicable to biodiversity conservation outside wilderness areas. Engaging public participation is crucial in this context to achieve social and environmental benefits. However, knowledge gaps remain in understanding how a balance between conservation and public demands can be reached and how complicated sociocultural contexts in the Anthropocene can be incorporated in conservation planning. We examined China's nationwide conflict between free-ranging cats (owned cats that are allowed to go outdoors or homeless cats living outdoors) and wildlife to examine how a consensus between compassion and biodiversity conservation can help in decision-making. We surveyed a random sample of people in China online. Over 9000 questionnaires were completed (44.2% response). In aggregate, respondents reported approximately 29 million free-ranging owned cats and that over 5 million domestic cats per year become feral in mainland China. Respondents who were cat owners, female, and religious were more likely to deny the negative impacts of cats on wildlife and ongoing management strategies and more supportive of stray cat shelters, adoption, and community-based fund raising than nonowners, male, and nonreligious respondents (p < 0.05). Free-ranging cat ownership and abandonment occurred less with owners with more knowledge of biodiversity and invasive species than with respondents with less knowledge of these subjects (p < 0.05). We recommend that cat enthusiasts and wildlife conservationists participate in community-based initiatives, such as campaigns to keep cats indoors. Our study provides a substantially useful framework for other regions where free-ranging cats are undergoing rapid expansion.


Retos y oportunidades de las dimensiones humanas detrás del conflicto entre gatos y fauna Resumen Debido a que las actividades antropogénicas globales causan una enorme pérdida de la biodiversidad, la investigación sobre las dimensiones humanas es esencial para generar planes de manejo aplicables a la conservación de la biodiversidad fuera de las áreas silvestres. Es muy importante lograr que el público participe en este contexto para obtener los beneficios sociales y ambientales. Sin embargo, todavía existen vacíos en el conocimiento sobre cómo lograr el balance entre la conservación y las demandas públicas y cómo incorporar los contextos socioculturales complejos del Antropoceno a la planeación de la conservación. Analizamos el conflicto nacional entre los gatos libres (gatos callejeros o gatos domésticos que se les permite salir) y la fauna en China para estudiar cómo un consenso entre la compasión y la conservación de la biodiversidad puede ayudar en la toma de decisiones. Encuestamos en línea a una muestra aleatoria de personas en China. Se completaron más de 9000 cuestionarios (44.2% de respuesta). En total, los respondientes reportaron un aproximado de 29 millones de gatos libres y que más de cinco millones de gatos domésticos se vuelven ferales al año en China. Quienes respondieron y son dueños de gatos, mujeres y religiosos tuvieron la mayor probabilidad de negar los impactos negativos de los gatos sobre la fauna y de las estrategias actuales de manejo y de mostrar más apoyo por los refugios de gatos abandonados, la adopción y de la recaudación de fondos comunitaria que quienes no son dueños, no son religiosos y son hombres (p < 0.05). La propiedad de gatos libres y el abandono ocurrieron menos con los dueños con más conocimiento sobre la biodiversidad y las especies invasoras que con los respondientes con menos conocimiento sobre estos temas (p < 0.05). Recomendamos que los aficionados a los gatos y los conservacionistas de la fauna participen en las iniciativas comunitarias; por ejemplo, campañas para mantener a los gatos dentro de casa. Nuestro estudio proporciona un marco sustancialmente útil para otras regiones en donde los gatos libres se encuentran en rápida expansión.

RESUMEN

Combined water, sanitation, and handwashing (WSH) interventions could reduce fecal contamination along more transmission pathways than single interventions alone. We measured Escherichia coli levels in 3909 drinking water samples, 2691 child hand rinses, and 2422 toy ball rinses collected from households enrolled in a 2-year cluster-randomized controlled trial evaluating single and combined WSH interventions. Water treatment with chlorine reduced E. coli in drinking water. A combined WSH intervention improved water quality by the same magnitude but did not affect E. coli levels on hands or toys. One potential explanation for the limited impact of the sanitation intervention (upgraded latrines) is failure to address dog and livestock fecal contamination. Small ruminant (goat or sheep) ownership was associated with increased E. coli levels in stored water and on child hands. Cattle and poultry ownership was protective against child stunting, and domesticated animal ownership was not associated with child diarrhea. Our findings do not support restricting household animal ownership to prevent child diarrheal disease or stunting but do support calls for WSH infrastructure that can more effectively reduce household fecal contamination.
