A framing effect in the judgment of discrimination.

Discrimination is not only an objective fact but also a subjective judgment. While extensive research has studied discrimination as an objective fact, we study the judgment of discrimination and show that it is malleable while holding objective discrimination constant. We focus on a common situation in real life: the constituent groups in a candidate pool are unequal (e.g., fewer female candidates than male candidates for tech jobs), and observers (e.g., the public) see only one side of the decision outcome (e.g., only the hired applicants, not the rejected ones). Ten experiments reveal a framing effect: people judge the decision-maker (e.g., the tech firm) as more discriminatory against the minority in the candidate pool if people see the composition of the accepted candidates than if they see the composition of the rejected candidates, even though the information in the two frames is equivalent (i.e., knowing the information in one frame is sufficient to infer the information in the other). The framing effect occurs regardless of whether the decision-maker is objectively discriminatory, replicates across diverse samples (Americans, Asians, and Europeans) and types of discrimination (e.g., gender, race, political orientation), and has significant behavioral consequences. We theorize and show that the framing effect arises because, when judging discrimination, people overlook information that they could infer but is not explicitly given, and they expect equality in the composition of the constituent groups in their given frame. This research highlights the fallibility of judged discrimination and suggests interventions to reduce biases and increase accuracy.

Dissonance in the face of Alzheimer's disease breakthroughs: clinician and lay stakeholder acceptance, concerns and willingness to pay for emerging disease-modifying therapies.

BACKGROUND: Introducing new disease-modifying therapies (DMTs) for Alzheimer's disease demands a fundamental shift in diagnosis and care for most health systems around the world. Understanding the views of health professionals, potential patients, care partners and taxpayers is crucial for service planning and expectation management about these new therapies. AIMS: To investigate the public's and professionals' perspectives regarding (1) acceptability of new DMTs for Alzheimer's disease; (2) perceptions of risk/benefits; (3) the public's willingness to pay (WTP). METHOD: Informed by the 'theoretical framework of acceptability', we conducted two online surveys with 1000 members of the general public and 77 health professionals in Ireland. Descriptive and multivariate regression analyses examined factors associated with DMT acceptance and WTP. RESULTS: Healthcare professionals had a higher acceptance (65%) than the general public (48%). Professionals were more concerned about potential brain bleeds (70%) and efficacy (68%), while the public focused on accessibility and costs. Younger participants (18-24 years) displayed a higher WTP. Education and insurance affected WTP decisions. CONCLUSIONS: This study exposes complex attitudes toward emerging DMTs for Alzheimer's disease, challenging conventional wisdom in multiple dimensions. A surprising 25% of the public expressed aversion to these new treatments, despite society's deep-rooted fear of dementia in older age. Healthcare professionals displayed nuanced concerns, prioritising clinical effectiveness and potential brain complications. Intriguingly, younger, better-educated and privately insured individuals exhibited a greater WTP, foregrounding critical questions about healthcare equity. These multifaceted findings serve as a guidepost for healthcare strategists, policymakers and ethicists as we edge closer to integrating DMTs into Alzheimer's disease care.

Willingness to accept and participate in a Microsporidia MB-based mosquito release strategy: a community-based rapid assessment in western Kenya.

BACKGROUND: Microsporidia MB, an endosymbiont naturally found in Anopheles mosquitoes inhibits transmission of Plasmodium and is a promising candidate for a transmission-blocking strategy that may involve mosquito release. A rapid assessment was carried out to develop insight into sociodemographic factors, public health concerns, and malaria awareness, management, and prevention practices with the willingness to accept and participate in Microsporidia MB-based transmission-blocking strategy to develop an informed stakeholder engagement process. METHODS: The assessment consisted of a survey conducted in two communities in western Kenya that involved administering a questionnaire consisting of structured, semi-structured, and open questions to 8108 household heads. RESULTS: There was an overall high level of willingness to accept (81%) and participate in the implementation of the strategy (96%). Although the willingness to accept was similar in both communities, Ombeyi community was more willing to participate (OR 22, 95% CI 13-36). Women were less willing to accept (OR 0.8, 95% CI 0.7-0.9) compared to men due to fear of increased mosquito bites near homes. Household heads with incomplete primary education were more willing to accept (OR 1.6, 95% CI 01.2-2.2) compared to those educated to primary level or higher. Perceiving malaria as a moderate or low public health issue was also associated with a lower willingness to accept and participate. Experience of > 3 malaria cases in the family over the last six months and knowledge that malaria is transmitted by only mosquito bites, increased the willingness to accept but reduced the willingness to participate. Awareness of malaria control methods based on mosquitoes that cannot transmit malaria increases the willingness to participate. CONCLUSION: The study showed a high level of willingness to accept and participate in a Microsporidia MB-based strategy in the community, which is influenced by several factors such as community, disease risk perception, gender, education level, knowledge, and experience of malaria. Further research will need to focus on understanding the concerns of women, educated, and employed community members, and factors that contribute to the lower disease risk perception. This improved understanding will lead to the development of an effective communication strategy.

Navigating Public Policy Responses to a Pandemic: The Balancing Act Between Physical Health, Mental Health, and Household Income.

OBJECTIVE: During COVID-19, governments imposed restrictions that reduced pandemic-related health risks but likely increased personal and societal mental health risk, partly through reductions in household income. This study aimed to quantify the public's willingness to accept trade-offs between pandemic health risks, household income reduction, and increased risk of mental illness that may result from future pandemic-related policies. METHODS: A total of 547 adults from an online panel participated in a discrete choice experiment where they were asked to choose between hypothetical future pandemic scenarios. Each scenario was characterized by personal and societal risks of dying from the pandemic, experiencing long-term complications, developing anxiety/depression, and reductions in household income. A latent class regression was used to estimate trade-offs. RESULTS: Respondents state a willingness to make trade-offs across these attributes if the benefits are large enough. They are willing to accept 0.8% lower household income (0.7-1.0), 2.7% higher personal risk of anxiety/depression (1.8-3.6), or 3.2% higher societal rate of anxiety/depression (1.7-4.7) in exchange for 300 fewer deaths from the pandemic. CONCLUSION: Results reveal that individuals are willing to accept lower household income and higher rates of mental illness, both personal and societal, if the physical health benefits are large enough. Respondents placed greater emphasis on maintaining personal, as opposed to societal, mental health risk and were most interested in preventing pandemic-related deaths. Governments should consider less restrictive policies when pandemics have high morbidity but low mortality to avoid the prospect of improving physical health while simultaneously reducing net social welfare.

The dynamic feasibility of resisting (R), accepting (A), or directing (D) ecological change.

Ecological transformations are occurring as a result of climate change, challenging traditional approaches to land management decision-making. The resist-accept-direct (RAD) framework helps managers consider how to respond to this challenge. We examined how the feasibility of the choices to resist, accept, and direct shifts in complex and dynamic ways through time. We considered 4 distinct types of social feasibility: regulatory, financial, public, and organizational. Our commentary is grounded in literature review and the examples that exist but necessarily has speculative elements because empirical evidence on this newly emerging management strategy is scarce. We expect that resist strategies will become less feasible over time as managers encounter situations where resisting is ecologically, by regulation, financially, or publicly not feasible. Similarly, we expect that as regulatory frameworks increasingly permit their use, if costs decrease, and if the public accepts them, managers will increasingly view accept and direct strategies as more viable options than they do at present. Exploring multiple types of feasibility over time allows consideration of both social and ecological trajectories of change in tandem. Our theorizing suggested that deepening the time horizon of decision-making allows one to think carefully about when one should adopt different approaches and how to combine them over time.

La viabilidad dinámica de resistir (R), aceptar (A) o dirigir (D) el cambio ecológico Resumen Las transformaciones ecológicas ocurren por el cambio climático, lo que representa un reto para los enfoques tradicionales para decidir en torno a la gestión de tierras. El marco resistir­aceptar­dirigir (RAD) ayuda a los gestores a considerar cómo responder a este reto. Analizamos cómo la viabilidad de las opciones para resistir, aceptar y dirigir cambia de manera compleja y dinámica con el tiempo. Consideramos cuatro tipos distintos de viabilidad: regulatoria, económica, pública y de organización. Nuestro comentario está basado en la revisión bibliográfica y los ejemplos que existen, pero por necesidad tiene elementos especulativos ya que la evidencia empírica sobre esta estrategia emergente de gestión es escasa. Esperamos que las estrategias de resistir se vuelvan menos viables con el tiempo conforme los gestores encuentren situaciones en las que resistir no es viable de forma ecológica, económica, pública o por regulación. Al igual esperamos que cada vez más los marcos regulatorios permitan su uso, si el costo disminuye, y si el público los acepta, los gestores verán cada vez más viables las estrategias de aceptar y dirigir que las que utilizan actualmente. La exploración de varios tipos de viabilidad a lo largo del tiempo permite considerar las trayectorias sociales y ecológicas del cambio en conjunto. Nuestra teoría sugiere que profundizar en el horizonte temporal de las decisiones permite que se analice con cuidado sobre cuando se deben adoptar enfoques diferentes y cómo combinarlos con el tiempo.

The willingness and influencing factors to choose institutional elder care among rural elderly: an empirical analysis based on the survey data of Shandong Province.

BACKGROUND: The ageing of the population has become an escalating problem in China, which has led to an increasing demand for healthcare throughout society. The care services of elderly institutions, as a more mature way of aging, can alleviate various social problems brought about by ageing to a certain extent. The aim of this paper is to explore the degree of acceptance of institutional care by rural elderly people in Shandong Province and the factors that influence whether rural elderly people accept institutional care services. METHODOLOGY: Based on the theory of planned behavior, an analytical framework was constructed for the willingness of rural elderly people to receive nursing services from elderly care institutions. Using survey data from 192 rural elderly people in Shandong Province, descriptive statistics, binary logistic regression, and horizontal comparative analysis methods were used to analyze the willingness of rural elderly people to provide for the elderly and its influencing factors. RESULT: Only 17.71% of respondents expressed willingness to receive services from elderly care institutions. Among them, education level, trust in elderly care institutions, and support from adult children have a significant positive impact on whether rural elderly people receive nursing services from elderly care institutions; The number of children, the level of understanding of elderly care institutions, neighbors' choices of elderly care methods, and their ability to contribute to the family have a significant negative impact on whether rural elderly people receive nursing services from elderly care institutions. There are significant differences in the willingness and influencing factors of rural elderly people to provide for the elderly among different regions. CONCLUSION: The non-acceptance of institutional care by rural older people is a general phenomenon rather than a sample characteristic, thus justifying the supplementary status of institutional care services. The pension intention of the rural elderly in Shandong Province is obviously affected by personal will factors, and the influencing factors are various. The traditional concept of old-age care in Shandong province has a strong path-dependent effect on the choice of the rural elderly. There is heterogeneity in the willingness and influencing factors of the rural elderly in different regions and countries. Based on this, this paper puts forward the following suggestions: strengthen the spiritual and cultural construction of residents; The government should pay attention to the correct guidance of public opinion; And increase pension subsidies. It is hoped that reduce the burden of national elderly care through these suggestions.

Public knowledge, perception of and willingness-to-accept nuclear energy in China: Evidence from a representative national survey.

The Chinese government promotes nuclear energy development in the context of mitigating climate change. However, the large-scale development is still facing challenges related to the knowledge gap among the general public and the potential "not-in-my-back-yard" objection. Based on a representative national survey, we analyze Chinese people's knowledge and perceptions of nuclear energy and estimate their willingness-to-accept the potential risks of new nuclear programs in neighborhoods via the Contingent Valuation Method. Generally, more than half of people do not know anything about nuclear energy. The main factors influencing public knowledge are identified, such as the residential distance to existing nuclear power stations and the frequency of internet use. Moreover, approximately 12% of individuals with some knowledge seem to be willing to accept new nuclear power plants in their neighborhoods with no compensation needed. Specifically, the perceptions of nuclear risks and pollution from fossil fuels are significant factors influencing people's acceptance of nuclear energy. Although public knowledge does not directly influence acceptance, more knowledge seems to reduce risk perception and increase benefit perception. The residential distance to exiting nuclear stations has limited effects on people's acceptance of newly planned nuclear programs for those living in the same county with some knowledge. In general, a typical Chinese household is willing to accept USD $5.66 every month or USD $67.97 every year to bear the potential risks of the new nuclear program in neighborhoods. Significant practical implications that can be transferable to other new energy technologies and countries or regions are provided.

Are nurses and patients willing to work with service robots in healthcare? A mixed-methods study.

INTRODUCTION: Scholars have become increasingly interested in incorporating robots into healthcare. While there is a growing body of research examining nurses' and patients' attitudes towards using robots in healthcare, no prior research has specifically explored their willingness to integrate service robots within the Egyptian healthcare context. AIM: The aim of this study was twofold: (a) to explore the behavioral intentions of nurses to accept robots in their workplace, and (b) to examine the willingness of patients to use service robots in healthcare settings. METHODS: A mixed-methods study was conducted. Quantitative data were collected from 301 nurses using the Behavioral Intention to Accept Robots in the Workplace Scale and from 467 patients using the Service Robot Integration Willingness Scale through convenience sampling at three tertiary public hospitals in Port Said, Egypt. Qualitative data were obtained through in-depth, semi-structured interviews with 16 nurses, focusing on their perspectives and concerns regarding robot integration. Descriptive analyses were used to analyze quantitative data, and thematic analysis was used to analyze qualitative data. RESULTS: Quantitative results indicated a moderate level of behavioral intention to use robots among nurses. Patients demonstrated low willingness to use service robots. In the qualitative analysis of the data obtained from the interviews with nurses, three categories (Concerns about Robots, Roles and Competencies, and Potential Benefits) and eight themes (interaction and emotions, maintenance and reliability, job insecurity, role clarity, competence in critical care, trustworthiness, reducing physical strain, and specialized applications) were identified. CONCLUSION: The results of this study indicate that nurses' behavioral intention to accept service robots in healthcare settings is moderate and their acceptance is influenced by various factors related to their concerns about robots, roles and competencies, and potential benefits they could gain. Patients showed a low level of willingness to use service robots in healthcare settings. IMPLICATION: Providing targeted educational programs to nurses and patients, assuring them with the provision of robust maintenance protocols, enhancing their confidence in the capabilities of robots, and defining clear roles for robots are crucial for the successful integration of robots into healthcare settings.

Postfire futures in southwestern forests: Climate and landscape influences on trajectories of recovery and conversion.

Southwestern ponderosa pine forests are vulnerable to fire-driven conversion in a warming and drying climate, yet little is known about what kinds of ecological communities may replace them. To characterize postfire vegetation trajectories and their environmental determinants, plant assemblages (361 sample plots including 229 vascular plant species, surveyed in 2017) were sampled within eight burns that occurred between 2000 and 2003. I used nonmetric multidimensional scaling, k-means clustering, principal component analysis, and random forest models to assess relationships between vegetation pattern, topographic and landscape factors, and gridded climate data. I describe seven postfire community types, including regenerating forests of ponderosa pine, aspen, and mixed conifers, shrub-dominated communities of Gambel oak and mixed species, and herb-dominated communities of native bunchgrasses and mixtures of ruderal, native, and nonnative species. Forest recovery was generally associated with cooler, mesic sites in proximity to forested refugia; shifts toward scrub and grassland types were most common in warmer, dryer locations distant from forested refugia. Under future climate scenarios, models project decreases in postfire forest recovery and increases in nonforest vegetation. However, forest to nonforest conversion was partially offset under a scenario of reduced burn severity and increased retention of forested refugia, highlighting important management opportunities. Burning trends in the southwestern United States suggest that postfire vegetation will occupy a growing landscape fraction, compelling renewed management focus on these areas and paradigm shifts that accommodate ecological change. I illustrate how management decisions around resisting, accepting, or directing change could be informed by an understanding of processes and patterns of postfire community variation and likely future trajectories.

Monetary valuation of COVID-19 informal care: caregivers' willingness to pay and willingness to accept.

BACKGROUND: Informal care can reduce hospitalization frequency and time, elevate bed turnover, and increase the health systems' capacity. This type of care has shown meaningful value in managing many cases through the COVID-19 pandemic. The present study aimed to identify determinants of monetary valuation of informal care and the burden of this care on the COVID-19 patients' caregivers. METHODS: Through a cross-sectional phone survey from June to September 2021 in Sanandaj city, the west of Iran, COVID-19 patients and their caregivers (Each Group No. 425) were separately interviewed. A simple probabilistic sampling method was applied. Two questionnaires were developed and used after validation. Monetary valuation of informal caregivers was done using Willingness to pay (WTP) and willingness to accept (WTA). Double hurdle regressions were used to determine related variables to WTP/WTA. R software was used for the data analysis. RESULTS: The total mean (Standard Deviation) of WTP and WTA were $12.02(28.73), $10.30(15.43) USD. Most respondents put a zero value on informal care by WTA (243(57.18%) and WTP [263 (61.88%)]. Caregivers' Employment, and being spouse/child of the care recipient increased the probability of reporting a positive value for WTP (p-value < 0.0001, p-value = 0.011 respectively) and WTA (p-value = 0.004, p-value < 0.0001 respectively). An increase in the number of caring days decreased the probability of reporting positive WTA (p-value = 0.001) and increased the mean of lnWTP (p-value = 0.044). Perceived difficulty in doing indoor activities and perceived difficulty in doing outdoor activities decreased lnWTA mean (p-value = 0.002) and lnWTP mean (p-value = 0.043) respectively. CONCLUSIONS: Increasing caregivers' self-efficacy and facilitating their involvement in the caring process could be facilitated through flexible work status, educational programs, and interventions on decreasing their burnout.

On implementing Jeffreys' substitution likelihood for Bayesian inference concerning the medians of unknown distributions.

When statisticians are uncertain as to which parametric statistical model to use to analyse experimental data, they will often resort to a non-parametric approach. The purpose of this paper is to provide insight into a simple approach to take when it is unclear as to the appropriate parametric model and plan to conduct a Bayesian analysis. I introduce an approximate, or substitution likelihood, first proposed by Harold Jeffreys in 1939 and show how to implement the approach combined with both a non-informative and an informative prior to provide a random sample from the posterior distribution of the median of the unknown distribution. The first example I use to demonstrate the approach is a within-patient bioequivalence design and then show how to extend the approach to a parallel group design.

Preferences for Conditional Economic Incentives to Improve Pre-exposure Prophylaxis Adherence: A Discrete Choice Experiment Among Male Sex Workers in Mexico.

Pre-exposure prophylaxis (PrEP) is highly effective in preventing HIV but requires sustained adherence. Conditional economic incentives (CEIs) can improve medication-taking behaviors, yet preferences for programs that employ CEIs to increase PrEP use among male sex workers (MSWs) have not been investigated. We conducted a discrete choice experiment in Mexico City to elicit stated preferences for a CEI-based PrEP adherence program among MSWs. Respondents expressed their preferences for different program characteristics: incentive amount; incentive format; incentive type; and adherence-verification method. We used a random utility logit model to estimate the relative importance of each attribute and estimated willingness-to-pay. MSWs preferred a higher, fixed incentive, with PrEP adherence measured via hair sampling. MSWs were willing to forego up to 21% of their potential maximum CEI amount to ensure receipt of a fixed payment. MSWs are highly willing to accept a CEI-based intervention for PrEP adherence, if offered along with fixed payments.

RESUMEN: La profilaxis previa a la exposición (PrEP) es muy eficaz para prevenir el VIH, pero requiere una adherencia sostenida. Los incentivos económicos condicionales (IEC) pueden mejorar los comportamientos de toma de medicamentos, sin embargo, no se han investigado las preferencias por los programas que emplean IEC para aumentar el uso de PrEP entre los trabajadores sexuales masculinos (TSM). Realizamos un experimento de elección discreta con TSM en la Ciudad de México para obtener preferencias declaradas para un programa de adherencia a la PrEP basado en IEC. Los participantes expresaron sus preferencias en cuanto a diferentes características: monto del incentivo; formato del incentivo; tipo de incentivo; y método de verificación de la adherencia. Utilizamos un modelo logit de utilidad aleatoria para estimar la importancia relativa de cada atributo y la disposición a pagar estimada (DAP). Los TSM prefirieron un incentivo fijo más alto, con la adherencia a la PrEP medida a través de muestras de cabello. Los TSM estaban dispuestos a renunciar hasta el 21% de su monto máximo potencial de IEC para garantizar la recepción de un pago fijo. Los TSM están muy dispuestos a aceptar una intervención basada en IEC para la adherencia a la PrEP, si se ofrece junto con pagos fijos.

Determinants of willingness to accept child vaccination against malaria in Ghana.

BACKGROUND: Malaria is a public health problem in Ghana with children being one of the most vulnerable. Given this, in 2019, Ghana decided to add the first malaria vaccine (RTS, S) as part of routine immunisations for children in the near future. This study, thus, examines the determinants of malaria vaccine awareness and willingness to uptake the vaccine for children in Ghana. METHOD: The study uses data from the 2019 Ghana Malaria Indicator Survey while employing the binary logistic regression as the empirical estimation technique. RESULTS: The study finds that religion, region of residence and awareness of the malaria vaccine, influence the willingness to uptake the vaccine for children. Moreover, younger mothers (15-26 years), households in the richest wealth quintile, male-headed households and the number of children aged five years and below in a household, are found to be associated with less willingness to uptake the vaccine for children. CONCLUSION: Paying attention to awareness creation, region, religion, younger mothers (15-26 years), households in the richest wealth quintile, male-headed households and households with more children aged five years and below, can ensure optimal uptake of the malaria vaccine for children in Ghana.

Seemingly bounded knowledge, trust, and public acceptance: How does citizen's environmental knowledge affect facility siting?

Understanding the mechanism of public perception and behavior towards environmental goods provision is essential for effective sustainable governance. This paper studies how citizens' self-reported environmental knowledge affects their trust in public service providers and subsequently their decisions about accepting the provision of a pollution management facility in their neighborhood. Utilizing unique survey data on the siting of a facility for waste incineration in Guangzhou, China, we find that the public's perceived environmental knowledge damages their trust in the operator, which lowers their acceptance of the facility siting, while damage to their trust in the government is negligible. In addition, we find that citizens' preferences for the type of information disclosed and the channels used for disclosure can affect public trust and thus acceptance of the facility siting. Therefore, policy suggestions for urban planning for sustainability are that the urban planner and policy maker can mitigate the negative consequences of bounded environmental knowledge by ensuring there is appropriate information disclosure. This study broadens our understanding of public recognition and acceptance of environmental goods provision and provides practical suggestions for sustainable development.

Understanding Fishermen's Willingness and Preferences for Eco-compensation of Lake Conservation Projects: A Case Study From Nansi Lake Nature Reserve, China.

Lake regions face a tradeoff between water environmental conservation and social development. Although lake conservation projects along with eco-compensation policies are considered the solutions to this problem, it is often controversial and unsustainable. Therefore, it is essential to understand the key stakeholders' willingness to participate in lake conservation projects under the different compensation schemes. In this work, we conducted a choice experiment to estimate fishermen's willingness and preference for the returning fishponds to lake (RFTL) project in the Nansi Lake Nature Reserve (NLNR). Socioeconomic, perception and spatial factors are employed to analyze the preference heterogeneity of fishermen. We employed conditional logit, mixed logit and latent class models to estimates the parameters of factor variables considering the heterogeneous preferences and choice randomness across respondents. The results indicate that on average, fishermen are unwilling to change the status quo and are most concerned about the subsidy amount and contract duration in compensation contracts. However, there is obvious spatial heterogeneity in fishermen's choice preference, mainly manifested in their habitation distance to a town and fishpond location in different zones of the NLNR. Specifically, perceptions of supply and demand for water yield and water quality services significantly influence fishermen's choice, but they have opposite effects. Moreover, we estimated marginal willingness to accept (MWTA) of attributes in compensation contract and measured compensating surplus (CS) to compare different eco-compensation policy scenarios. Our results contribute to designing targeted payment policies, and promote the effective implementation of lake conservation projects and regional sustainable development.

Resisting-Accepting-Directing: Ecosystem Management Guided by an Ecological Resilience Assessment.

As anthropogenic influences push ecosystems past tipping points and into new regimes, complex management decisions are complicated by rapid ecosystem changes that may be difficult to reverse. For managers who grapple with how to manage ecosystems under novel conditions and heightened uncertainty, advancing our understanding of regime shifts is paramount. As part of an ecological resilience assessment, researchers and managers have collaborated to identify alternate regimes and build an understanding of the thresholds and factors that govern regime shifts in the Upper Mississippi River System. To describe the management implications of our assessment, we integrate our findings with the recently developed resist-accept-direct (RAD) framework that explicitly acknowledges ecosystem regime change and outlines management approaches of resisting change, accepting change, or directing change. More specifically, we developed guidance for using knowledge of desirability of current conditions, distance to thresholds, and general resilience (that is, an ecosystem's capacity to cope with uncertain disturbances) to navigate the RAD framework. We applied this guidance to outline strategies that resist, accept, or direct change in the context of management of aquatic vegetation, floodplain vegetation, and fish communities across nearly 2000 river kilometers. We provide a case study for how knowledge of ecological dynamics can aid in assessing which management approach(es) are likely to be most ecologically feasible in a changing world. Continued learning from management decisions will be critical to advance our understanding of how ecosystems respond and inform the management of ecosystems for desirable and resilient outcomes.

How much is policy driving the adoption of cover crops? Evidence from four EU regions.

EU agriculture is facing increasing expectations and pressure from society and policymakers to support environmental protection and climate change mitigation. Catch and cover crops (CCC) are an underused farming practice that can potentially contribute towards these goals. Previous research is sparse and has yielded few relevant insights into CCC adoption behaviour by farmers. In this study we analyse a dataset from farm surveys in four EU regions to better understand the role of policy and non-policy factors in CCC adoption. Our data suggests that adoption rates vary widely between regions, while farm adoption intensities are low. We find that policy is by far the strongest determinant of adoption rates and adoption intensities. CCC adoption patterns have been shaped mainly by the Nitrates Directive and the Common Agricultural Policy's greening requirements. Agronomic motives are a third but much weaker impetus for adoption. Environmental and climate change considerations do not play a significant role in farmers' adoption decisions. Most non-adopters would likely become adopters if stronger policy obligations or additional subsidies were implemented. Non-adopters' responsiveness to subsidies and willingness to accept is highly varied but only weakly predictable from easily observed farm characteristics.

Kicking the habit is hard: A hybrid choice model investigation into the role of addiction in smoking behavior.

Use of choice models is growing rapidly in tobacco research. These models are being used to answer key policy questions. However, certain aspects of smokers' choice behavior are not well understood. One such feature is addiction. Here, we address this issue by modeling data from a choice experiment on the US smokers. We model addiction using a latent variable. We use this latent variable to understand the relationship between choices and addiction, giving attention to nicotine levels. We find that more addicted smokers have stronger preferences for cigarettes and are unwilling to switch to e-cigarettes. Addicted smokers value nicotine in tobacco products to a much greater extent than those that are less addicted. Lastly, we forecast short-term responses to lowering nicotine levels in cigarettes. The results suggest that current nicotine-focused policies could be effective at encouraging addicted smokers to less harmful products and lead to substantial public health gains.

Willingness to bear economic costs of measures against SARS-CoV-2 in Germany.

BACKGROUND: The aim of this study was to assess the willingness of the general population in Germany to bear the economic costs of measures against the spread of SARS-CoV-2. METHODS: Repeated cross-sectional data were taken from three waves of a nationally representative survey of individuals aged 18 to 74 years (wave 8: 21-22 April 2020, N = 976; wave 16: 7-8 July 2020, N = 977; wave 38: 9-10 March 2021). The willingness to accept a reduction of annual household income in order to bear the economic costs of the measures against SARS-CoV-2 served as outcome measure. Two-part models were used including explanatory variables on sociodemographic and (subjectively assessed) potential health hazard caused by COVID-19. RESULTS: 65.5% (61.6%; 56.9%) of respondents in wave 8 (wave 16; wave 38) were willing to accept a reduction of income, with the likelihood for accepting a reduction of income being positively associated with higher affect (i.e. emotional reaction) and presumed severity regarding COVID-19 in all three waves. The mean maximum percentage of income participants were willing to give up was 3.3% (95% CI: 2.9 to 3.7%) in wave 8, 2.9% (95% CI: 2.5 to 3.3%) in wave 16 and 4.3% (95% CI: 3.6 to 5.0%) in wave 38, with presumed severity of COVID-19 being positively associated with this percentage in all three waves. CONCLUSIONS: The majority of respondents indicated willingness to sacrifice income in order to bear the costs of measures against the spread of SARS-CoV-2, with the potential health hazard caused by COVID-19 being consistently associated with this willingness. However, the proportion of individuals who were willing to give up income slightly decreased throughout the pandemic.

How do patients prefer specialized clinical pharmacy service to other prevention of mother-to-child transmission of human immunodeficiency virus services? An evaluation of their willingness to pay and willingness to accept choices and ratios.

WHAT IS KNOWN AND OBJECTIVE: Donor agencies provide most of the funds for HIV services in developing countries. Due to the global economic downturn, there has been a reduction in funding for HIV-related services in Nigeria. This study compared the willingness to pay (WTP)-willingness to accept (WTA) ratios for prevention of mother-to-child transmission (PMTCT) services to specialized clinical pharmacy services among patients of two Nigerian hospitals. METHODS: This was a cross-sectional survey using contingent valuation method at Ahmadu Bello University Teaching Hospital (ABUTH) and University of Nigeria Teaching Hospital (UNTH). WTP and WTA were elicited using an interviewer-administered questionnaire and a payment card. The responses to the WTP and WTA questions were reported as frequencies and percentages, while the amounts were determined as mean. All costs were obtained in Nigerian Naira (N360 = $1). RESULTS AND DISCUSSION: Of the 219 mothers who participated in the study, 172 (78.5%) had no health insurance. Primary prevention of HIV (PPV) had the highest "yes" WTP response of 152 (69.4%) and the highest mean WTP amount of N6067.20. It also had the least "no" WTA response of 162 (74.0%) and the least WTA amount of N232.09. Specialized clinical pharmacy service (SCPS) had the highest WTA/WTP ratio of 4.0826 in ABUTH and 9.3750 at UNTH. Its income effect was -3.0826. A 1% increase in income led to 0.0550 (95% CI: -0.3068 to 0.1968) decreased odds to pay for PPV. WHAT IS NEW AND CONCLUSION: Most patients assessed in this study were willing to pay for PPV than other services. Majority of them were also willing to forgo PMTCT Drugs Only. SCPS had the highest value for the patients, but they did not want to pay a high amount for it. Employment status, health insurance status, educational level and age were predictors of patients' WTP and WTA.
