Integration of preference heterogeneity into sustainable nature conservation: From practice to policy

The aim of this work is to assess and understand the social drivers that determine the willingness to pay for sustainable management measures to preserve a Natura 2000 area. These social drivers of the support for nature conservation were then included in the design of economic instrument to support nature conservation. In a contingent valuation exercise, the local population in the Cabezo de la Jara and Rambla de Nogalte protected areas (SE Spain) stated their willingness to pay for sustainable management measures aimed at their conservation. Among the socio-demographics, environmental attitudes and experiential drivers, income and environmental commitment were found to be the only significant drivers in support of nature conservation, revealing preference heterogeneity. Economic instruments, specifically green taxes and user fees, are proposed, taking into account the sources of heterogeneity in order to ensure financial support for the measures and greater social acceptability. Hence, our research adds to the existing literature through the design of an economic instrument to support nature conservation, considering preference heterogeneity.     

Indirect reciprocity and tradeoff paradigms in the wake of violent intergroup conflict

Intergroup interaction can be hindered by legacies of conflict and group biases. Many studies have looked at intergroup attitudes and pro-sociality in the wake of intergroup conflict, but few have explicitly studied how the group affiliation of another person affects the willingness to interact economically, especially when the interactions concern contested issues. In this study, I investigate the effect of group affiliation on the willingness to engage in economic interactions with others among individuals exposed to violent intergroup conflict, using a sample of refugees from the conflicts in Syria and Iraq. Based on the theory of indirect reciprocity, it is predicted that the tradeoff paradigms, that is, the willingness to engage in economic transactions with another individual, will depend on previous actions of other members of that individual's group. Participants tended to adopt a communal sharing tradeoff paradigm with ingroup members, and they tended to adopt a market pricing paradigm with outgroup members. However, this was the case only for those who reported that outgroup members had taken actions to harm them or their family in the conflict. For those who reported being harmed by members of the ingroup, a market pricing paradigm was employed also with ingroup members. The results suggest that group biases and indirect reciprocity after violent conflict do not necessarily arise from group identities alone, but as a function of past interactions with outgroup members.     

Factors That Influence Parental Attitudes toward Enrollment in Type 1 Diabetes Trials

Aims

To assess parental attitudes towards type 1 diabetes clinical trials (T1DCTs) and factors that impact willingness to enroll their children with and without diabetes.

Methods

A cross-sectional survey of parents of children with type 1 diabetes was administered at an academic clinic and a diabetes educational event.

Results

Survey response rate was 36%. Of 166 participating parents, 76% were aware of T1DCTs. More parents reported willingness to enroll children with diabetes (47%) than unaffected children (36%). Only 18% recalled being asked to enroll their children, and of these, 60% agreed to enroll at least some of those times. Less than 30% were comfortable with placebos. Factors predicting willingness to enroll children with diabetes included healthcare provider trust, comfort with consent by proxy, low fear of child being a “guinea pig,” and comfort with placebo. Factors predicting willingness to enroll unaffected children were provider trust, comfort with consent by proxy, comfort with placebo, and perceived ease of understanding T1DCT information.

Conclusions

Parents report moderate willingness to enroll children in T1DCTs. Willingness is diminished by common trial methodologies. Although most parents recalled receiving trial-related information, significantly fewer recalled being asked to participate. Efforts to optimize effective communication around identified areas of parental concern may increase T1DCT participation.     

Cues of parental investment as a factor in attractiveness

One prediction derived from parental investment theory is that women will be more attentive than men are to cues of a prospective mate's dispositions to invest in children. Research with 1793 Internet participants, representing a diverse population sample, found that (a) women tend to be generally more critical than men are in their evaluations of potential mates, but not potential friends or neighbors, and (b) cues of a positive disposition towards parental investment (DPI) have a positive influence on female evaluations of the attractiveness of males. This latter effect, however, is less domain-specific than previous research [La Cerra, M. M. (1995). Evolved mate preferences in women: Psychological adaptations for assessing a man's willingness to invest in offspring (doctoral dissertation, University of California, Santa Barbara). Dissertation Abstracts International: Section B: the Sciences & Engineering Mar, 55(9-B), 4149] indicated; it is not limited to mating contexts and to cues focusing on parental investment. In fact, much of the sex difference appears to be due to indifference by males towards cues of female DPI. A second study further clarified that the previous findings were not due solely to the Internet methodology or the immediate accessibility of images being evaluated.     

A Blessing and a Curse? Political Institutions in the Growth and Decay of Generalized Trust: A Cross-National Panel Analysis, 1980–2009

Despite decades of research on social capital, studies that explore the relationship between political institutions and generalized trust-a key element of social capital-across time are sparse. To address this issue, we use various cross-national public-opinion data sets including the World Values Survey and employ pooled time-series OLS regression and fixed- and random-effects estimation techniques on an unbalanced panel of 74 countries and 248 observations spread over a 29-year time period. With these data and methods, we investigate the impact of five political-institutional factors-legal property rights, market regulations, labor market regulations, universality of socioeconomic provisions, and power-sharing capacity-on generalized trust. We find that generalized trust increases monotonically with the quality of property rights institutions, that labor market regulations increase generalized trust, and that power-sharing capacity of the state decreases generalized trust. While generalized trust increases as the government regulation of credit, business, and economic markets decreases and as the universality of socioeconomic provisions increases, both effects appear to be more sensitive to the countries included and the modeling techniques employed than the other political-institutional factors. In short, we find that political institutions simultaneously promote and undermine generalized trust.     

国家公园农户对野生动物肇事保险购买意愿及其影响因素——以大熊猫国家公园为例

国家公园内人与野生动物冲突严重,建立野生动物肇事保险机制是减缓冲突的重要举措。以大熊猫国家公园周边社区为例,分析建立国家公园以及农户风险偏好对野生动物肇事保险购买意愿的影响,并探讨冲突程度和制度信任的中介效应。研究结果表明建立国家公园显著增加了农户野生动物肇事保险购买意愿,而农户风险偏好对保险购买意愿会产生负向显著影响。冲突程度和制度信任是重要的中介变量,冲突程度和制度信任均对农户保险购买意愿产生正向显著影响。建立国家公园显著增加了人与野生动物冲突严重程度,进而对保险购买意愿产生正向影响。此外,建立国家公园显著降低了农户制度信任,进而对保险购买意愿产生负向影响。农户风险偏好对野生动物肇事损失程度产生正向显著影响,进而对保险购买意愿产生正向影响。农户风险偏好对制度信任影响并不显著。基于此,研究提出吸纳社会资本参与,拓宽野生动物肇事保险资金来源,开展社区共管、地役权补偿等措施提升社区信任以及建立基于农户自主防护行为的野生动物肇事保险机制等政策建议。     

Public Knowledge of,and Attitudes to,Frogs in Colombia

ABSTRACT

People's response to the decline of biodiversity and their support for conservation measures depends on their knowledge of biodiversity and their attitudes to local species. This study is one of the first to investigate public knowledge of, and attitudes to, frogs in South America. We chose two study regions, the semi-urban region of Pensilvania and the rural region of Florencia. In spring 2011, 565 individuals completed a written questionnaire and a subsequent picture test. Overall, the public's attitudes to, and knowledge of frogs, were rather poor. Direct experiences and community elders were the major source of knowledge of frogs for participants in Florencia, whereas electronic media was the main source of knowledge in Pensilvania. Most participants felt that frogs are of high conservation value and important for medical and ecological purposes. The more strongly participants agreed that frogs are useful, of medicinal value, and beautiful, the more strongly they agreed that they should be conserved. Our results indicate that conservation education activities in schools and elsewhere are needed to improve people's knowledge of, and attitudes to, frogs. More positive attitudes toward local amphibian species might lead to an appreciation of their value and willingness to conserve them.     

Attracting mates: Effects of paternal investment on mate attraction strategies

It is proposed here that mate-attraction strategies among females and among males vary facultatively with expectations about paternal investment. The following four hypotheses are argued and tested: 1. Females who expect to find investing mates will be more likely than other females to emphasize their need for investment by suppressing their resources and appearance of competence. 2. Females who expect to find investing mates will try to attract them by acting chaste and emphasizing their fidelity, while females who expect non-investing mates will flaunt their sexuality in order to get pre-reproductive investment from as many males as possible. 3. Males who think it is appropriate to invest heavily in offspring will be more likely than other males to attract mates by emphasizing their ability and willingness to invest. 4. Investing males will be more likely than non-investing males to emphasize chastity and fidelity, whereas non-investing males will flaunt their sexuality and sexual attractiveness to females.These hypotheses were evaluated among undergraduates by administering questionnaires measuring (a) attitudes toward paternal investment and (b) reported tactics used to attract mates. Hypotheses 2–4 were supported by the data, while hypothesis 1 received only partial support. The mixed results for hypothesis 1 indicate that self-deprecating acts and deferential acts may be signaling different things.     

Evolutionary dynamics of strategic behavior in a collective-risk dilemma

A collective-risk social dilemma arises when a group must cooperate to reach a common target in order to avoid the risk of collective loss while each individual is tempted to free-ride on the contributions of others. In contrast to the prisoners' dilemma or public goods games, the collective-risk dilemma encompasses the risk that all individuals lose everything. These characteristics have potential relevance for dangerous climate change and other risky social dilemmas. Cooperation is costly to the individual and it only benefits all individuals if the common target is reached. An individual thus invests without guarantee that the investment is worthwhile for anyone. If there are several subsequent stages of investment, it is not clear when individuals should contribute. For example, they could invest early, thereby signaling their willingness to cooperate in the future, constantly invest their fair share, or wait and compensate missing contributions. To investigate the strategic behavior in such situations, we have simulated the evolutionary dynamics of such collective-risk dilemmas in a finite population. Contributions depend individually on the stage of the game and on the sum of contributions made so far. Every individual takes part in many games and successful behaviors spread in the population. It turns out that constant contributors, such as constant fair sharers, quickly lose out against those who initially do not contribute, but compensate this in later stages of the game. In particular for high risks, such late contributors are favored.     

Exploring the hidden impact of the Covid-19 pandemic: The role of urbanization

We examine the role of residential environments (urban/rural) in understanding the impact of the COVID-19 pandemic and the restrictions in nationwide movement on several socio-economic attitudes. We conducted large-scale surveys in four European countries (France, Germany, Spain, and the United Kingdom) before and after nationwide lockdowns were implemented. We investigate how the pandemic affected: (i) economic (economic insecurity), (ii) political (trust in domestic and international institutions), and (iii) social attitudes (loneliness), by controlling for the degree of urbanization, obtained from the geocodes of the survey respondents. Our results show that taking the degree of urbanization into account is not only relevant but is also essential. Compared to urban areas, in rural areas lockdowns led to a greater increase of economic insecurity and to a greater decrease in trust in domestic institutions. We also show that these results are particularly valid for women and households with children.     

Focus group interviews examining attitudes toward medical research among the Japanese: a qualitative study

Objectives: the purpose of ths study is to explore laypersons' attitudes towards and experiences of medical research, and to compare them with those of physicians in Japan. Designs and Participants: fourteen Japanese adults from the general public and seven physicians participated in one of three focus interviews. Setting: Osaka, Japan. Results: trust and distrust in the physician by whom the participants were invited to participate in research played a considerable role in their decisions about participation. That the participants felt an obligation to participate was also expressed. The lay participants perceived medical research as something entirely outside of their world. A greater willingness to volunteer for research was expressed if there were direct benefits to themselves or their families. Research methods such as use of placebos, double blinds, and randomisations seemed to cause negative attitudes to medical research. All physicians were convinced of the need for medical research, including double-blinded randomised control trials, and its significant role in medical progress. Most physicians thought that the greater awareness of the need for medical research in the community and a better understanding of the psychology of potential research participants were necessary and urgent. Conclusions: there is a good possibility that the lay public and medical professionals have sharply different beliefs about and attitudes towards every aspect of medical research. Building up a better and equal patient-doctor relationship based on trust is a key issue in medical research, and it is mandatory to fill the gap in perception regarding medical research between them through fully informed debates.     

An agent‐based modelling approach to evaluate factors influencing bioenergy crop adoption in north‐east Scotland

An agent‐based modelling (ABM) framework was adapted to assess bioenergy crop uptake and integrate social and economic processes with biophysical elements. Survey results indicated that economic rationalisation was intrinsic to farmers’ decision‐making, but was not the only consideration. This study presents an approach, set within an established resource management framework, to incorporate a number of key socio‐economic factors, which we call Mitigation Willingness Factors (MWFs), using survey data collected from farmers and land managers, into the ABM. The MWFs represent farmers’ willingness to compromise revenue in order to reduce GHG emissions, derived from their attitudes to climate change and the ability of different economic mechanisms to stimulate energy crop uptake. Adoption of bioenergy crops of different farmer types and farming enterprises was also assessed. Adoption rates and scenarios that take into account noneconomic factors are presented, and particular farming enterprises that may respond more positively to policy initiatives are identified.     

Low-investment copulation: Sex differences in motivations and emotional reactions

Samples of male (n = 113) and female (n = 175) college students were surveyed. Majorities of both sexes agreed with statements indicating that males' sexual attractiveness varied more than females' sexual attractiveness as a function of their status. Subjects who reported more sex partners and a greater aversion to sexual monogamy were slightly more likely to agree that they tested their partners to see how far they could push them. Interviews with highly sexually active females (n = 32) and males (n = 24) indicated that low-investment copulation and lack of control over the sexual access-investment ratio caused even women with very permissive attitudes and multiple sex partners to develop an aversion to low-investment copulation. Three levels were identified in this process. The techniques that women with multiple partners used to deal with their feelings are described. Females tested their partners for ability and willingness to invest. Males tested for opportunities to reduce investment and pursue other women. High status, for example athletic stardom, transformed males' sexual attractiveness to women and numbers of sex partners. Results were consistent with the view that the emotional-motivational mechanisms that moderate sexual arousal and attraction are sexually dimorphic.     

Back to the Future: revisiting the contact hypothesis at Turkish and mixed non-profit organizations in Amsterdam

This paper revisits the contact hypothesis by assessing differences in generalized trust among participants of Turkish non-profit organizations and ethnically mixed organizations in Amsterdam. Most voluntary sector research takes the contact hypothesis at its core and assumes that the concentration of ethnic minorities in non-profit organizations is detrimental to learning generalized trust. These studies assume that diversity within organizations is better for developing generalized norms without examining participation in ethnically homogenous organizations. I address this gap in the literature by analysing the variance of generalized trust among organizations and their participants. I achieve this through the analysis of purposively designed survey data. The findings suggest that a contact mechanism at voluntary organizations is problematic and should not be asserted uncritically.     

ADEQUATE TRUST AVAILS,MISTAKEN TRUST MATTERS: ON THE MORAL RESPONSIBILITY OF DOCTORS AS PROXIES FOR PATIENTS' TRUST IN BIOBANK RESEARCH

In Sweden, most patients are recruited into biobank research by non‐researcher doctors. Patients' trust in doctors may therefore be important to their willingness to participate. We suggest a model of trust that makes sense of such transitions of trust between domains and distinguishes adequate trust from mistaken trust. The unique position of doctors implies, we argue, a Kantian imperfect duty to compensate for patients' mistaken trust. There are at least three kinds of mistaken trust, each of which requires a different set of countermeasures. First, trust is mistaken when necessary competence is lacking; the competence must be developed or the illusion dispelled. Second, trust is irrational whenever the patient is mistaken about his actual reasons for trusting. Care must therefore be taken to support the patient's reasoning and moral agency. Third, some patients inappropriately trust doctors to recommend only research that will benefit them directly. Such trust should be counteracted by nurturing a culture where patients expect to be asked occasionally to contribute to the common good.     

The Potential Influence of a Companion-Animal's Presence on Aspects of the Therapeutic Alliance

ABSTRACT

Seventy-one college students participated in an experiment exploring the impact of a companion-animal's presence (viz., a dog) on several aspects of the participants' experience during an interview. Specifically, the study examined how the presence of a companion animal impacts participants' perception of the interviewer, including perceived levels of empathy and participants' willingness to self-disclose. Participants were prescreened with questions regarding past experience with animals. The researcher then conducted interviews with each participant, simulating a process comparable to that of an abridged initial psychotherapy intake session. Participants completed measures on their experience at the completion of the interview. Primary findings of the study determined that the presence of a companion animal did not influence participants' overall perceptions of the interviewer, willingness to self-disclose to the interviewer, and perceptions of the interviewer's level of empathic understanding. Participants' level of exposure to animals (current and past) also had no impact on these dependent measures. When participants' attitudes toward pets were examined, negative attitudes toward pets were associated with a diminished willingness to self-disclose in this study. This study represents an initial attempt at using more rigorous methodical controls to study the effect of companion animals in therapy-like situations. Contrary to previous research, the results imply that the presence of a companion animal during an interview analogous to the initial psychotherapy intake session may not influence aspects of the therapeutic alliance examined in this study. Future research is needed to determine if the same findings will be found with actual psychotherapy cases.     

Women Tend to Defect in a Social Dilemma Game in Southwest China

Cooperation theories assume that interacting individuals can change their strategies under different expected payoffs, depending on their social status or social situations. When looking at sex differences in cooperation, the existing studies have found that the genders cooperate at similar frequencies. However, the majority of the data originate within Western human societies. In this paper, we explore whether there are gender differences in cooperation in China. An Iterated Prisoner’s Dilemma game with a punishment option was used to gather data about Southwest Chinese subjects in a culture in which men have a hierarchical advantage over women. Results indicate that men invested into partners significantly more than women did (34% ♂ vs. 24% ♀) while women, in turn, were more likely to defect (65% ♀ vs. 50% ♂). In this region, women have customarily held less economic power and they are used to obtain a payoff typically lower than men. We suggest that the women’s willingness to invest in cooperation has decreased throughout evolutionary time, providing us with an illustration of a culturally-driven shift towards a disparity in gender cooperation interests.     

Economic Profits Enhance Trust,Perceived Integrity and Memory of Fairness in Interpersonal Judgment

Does money lead to trust in personality and intention of others? Humans have a strong tendency to judge the intention of others from their sequent behaviors. In general, people trust others who behave fairly, but not always. Here we show that judgments of both intentional aspects and memory of intentional behavior are automatically influenced by unintentional benefits from the behaviors of others. We conducted a reward-manipulated and repeated trust game by using real participants interacting with moving image partners on a computer screen. The participants assessed likability, trustworthiness, and perceived integrity of the partners in pre- and post-game questionnaires. The results of judgments of all three dimensions and the memory of frequency of each partner''s fair behavior (sharing) were strongly influenced by profitability in the trust game, even though all partners shared 75% of the profit and participants were told that profitability was randomly assigned to each partner. Furthermore, these effects were moderated by the gender of the participants: males were more sensitive to monetary profits than were females. The results reveal that humans automatically trust, approve the integrity of, and recall well the fair behavior of others who provide affectively positive outcomes such as monetary profits. We call this phenomenon the “affect ripple effect”.     

Capital and punishment: Resource scarcity increases endorsement of the death penalty

Faced with punishing severe offenders, why do some prefer imprisonment whereas others impose death? Previous research exploring death penalty attitudes has primarily focused on individual and cultural factors. Adopting a functional perspective, we propose that environmental features may also shape our punishment strategies. Individuals are attuned to the availability of resources within their environments. Due to heightened concerns with the costliness of repeated offending, we hypothesize that individuals tend towards elimination-focused punishments during times of perceived scarcity. Using global and United States data sets (studies 1 and 2), we find that indicators of resource scarcity predict the presence of capital punishment. In two experiments (studies 3 and 4), we find that activating concerns about scarcity causes people to increase their endorsement for capital punishment, and this effect is statistically mediated by a reduced willingness to risk repeated offenses. Perceived resource scarcity shapes our punishment preferences, with important policy implications.     

Factors Motivating Individuals to Consider Genetic Testing for Type 2 Diabetes Risk Prediction

The purpose of this study was to identify attitudes and perceptions of willingness to participate in genetic testing for type 2 diabetes (T2D) risk prediction in the general population. Adults (n = 598) were surveyed on attitudes about utilizing genetic testing to predict future risk of T2D. Participants were recruited from public libraries (53%), online registry (37%) and a safety net hospital emergency department (10%). Respondents were 37±11 years old, primarily White (54%), female (69%), college educated (46%), with an annual income ≥$25,000 (56%). Half of participants were interested in genetic testing for T2D (52%) and 81% agreed/strongly agreed genetic testing should be available to the public. Only 57% of individuals knew T2D is preventable. A multivariate model to predict interest in genetic testing was adjusted for age, gender, recruitment location and BMI; significant predictors were motivation (high perceived personal risk of T2D [OR = 4.38 (1.76, 10.9)]; family history [OR = 2.56 (1.46, 4.48)]; desire to know risk prior to disease onset [OR = 3.25 (1.94, 5.42)]; and knowing T2D is preventable [OR = 2.11 (1.24, 3.60)], intention (if the cost is free [OR = 10.2 (4.27, 24.6)]; and learning T2D is preventable [OR = 5.18 (1.95, 13.7)]) and trust of genetic testing results [OR = 0.03 (0.003, 0.30)]. Individuals are interested in genetic testing for T2D risk which offers unique information that is personalized. Financial accessibility, validity of the test and availability of diabetes prevention programs were identified as predictors of interest in T2D testing.
