A generalized war of attrition

In the “War of Attrition” model of animal conflict, introduced by Maynard Smith, a reward is obtained by whichever of two opponents displays longer, each individual incurring a cost associated with the length of the contest. This model is generalized to allow more general reward and cost functions, and restrictions on the length of contest permitted. This permits unification of the “War of Attrition” model and the “Graduated Risks” model, and also the extension to models in which contests may end either due to injury, or to retreat.In each case it is demonstrated that either (i) there is no evolutionary stable strategy (ESS) or (ii) there is a unique ESS, which is fully specified. In the case where only a finite number of pure strategies are available, global convergence to the ESS is shown.A variety of interesting conclusions of biological relevance emerge, perhaps the most striking being the occurrence of a dichotomous behavioural pattern in an essentially continuous conflict.     

Hindutva in the West: mapping the antinomies of diaspora nationalism

This introduction provides a historical background to Hindu nationalism and examines several theoretical and empirical themes that are important for its analysis both in India and the diaspora. It is argued that there has been a relative neglect within the research field of diaspora nationalist movements and the impact they can have on constituting antisecular and absolutist orientations to minorities and majorities both within the diaspora and in the “homeland”. The introduction examines the rise of the Hindutva movement in the 1920s and considers the debates about its relation to ethnic, nationalist, religious, racist and fascist ideologies. We consider how an examination of Hindu nationalism can modify many recent debates on “race” and ethnicity, multiculturalism and “diaspora”. Several themes relating to caste, gender and “Aryanism” are examined. The contents of this Special Issue are contextualized within these debates and a summary of the key themes of the contributions is provided.     

Towards a new politics of migration?

This paper reconsiders Stephen Castle’s classic paper Why Migration Policies Fail. Beginning with the so-called migration crisis of 2015 it considers the role of numbers is assessing success or failure. It argues that in the UK public debates about immigration changed with European Union (EU) Enlargement in 2004, when the emphasis shifted from concerns about asylum to concerns about EU mobility. Concerns were exacerbated by the government’s failure to meet its promise to reduce net migration. This policy is hampered by the general problem of definition of “migrant” and the gap between statistical measures and popular usage in which “migration” signifies problematic mobility. In fact, concern about migration has become a placeholder for concerns about globalization and democratic accountability. A new politics of migration must make connections between migrants and citizens, but also between migration and other global processes, particularly outsourcing and the exploitation of labour and resources in the global south.     

Diverse Varieties and Diverse Markets: Scale-related Maize “Profitability Crossover” in the Central Mexican Highlands

Discussions of maize agriculture in Mexico often treat “maize” as a uniform commodity, sold in a relatively homogeneous market, and for which there is a single, “economically rational” production strategy. Based on qualitative research on maize value chains, we suggest that this unitary notion entails significant oversimplifications. We offer a heuristic model of farm-size related “profitability crossover,” based on observations of highland maize varieties’ roles within a series of farm-cycle opportunities and constraints. We suggest that while improved maize varieties may be profitable for large-scale farms taking advantage of economies of scale, landrace cultivation may offer advantages to small- to medium-scale farmers, who utilize a diverse range of input strategies, and sell their products in specialty markets. Understanding maize agriculture as a multi-product and multi-market pursuit rather than uniform commodity production would add greater depth to policy and academic debates.     

利益相关者视角下的濒危物种价值评估与生态补偿——以翅果油树为例

濒危物种价值评估可为生物多样性保护提供重要的政策支撑。本文以国家二级重点保护植物翅果油树为例,从利益相关者视角作为切入点,基于选择实验法评价其偏好和支付意愿(WTP),进而探讨生态补偿机制。基于管理部门、企业和农户三方利益相关者的利益诉求,分析确定了5个翅果油树的物种属性,即种植面积、产品分类、树苗品种、保护投入和农户收益。运用随机参数Logit模型分析了利益相关者对不同物种属性变量的偏好和支付意愿。结果表明: 受访者对“保护增加投入”偏好最强和支付意愿最高,每户为331.00 yuan·a^-1;对产品开发的“高低端产品同时开发”和“高端产品开发为主”变量偏好次之,WTP分别为每户242.71和227.57 yuan·a^-1;对“农户收益”、“保护投入不变”、“树苗品种”和“种植面积”由强到弱依次表现出一定的偏好及支付意愿;而对“保护不投入”和“低端产品开发为主”偏好最弱且WTP为负值。通过直接和间接补偿方式对补偿客体(翅果油树及其生境)实施生态补偿,得到的补偿剩余价值为每户每年285.62元。     

THE ROLES OF LIFE‐HISTORY SELECTION AND SEXUAL SELECTION IN THE ADAPTIVE EVOLUTION OF MATING BEHAVIOR IN A BEETLE

Although there is continuing debate about whether sexual selection promotes or impedes adaptation to novel environments, the role of mating behavior in such adaptation remains largely unexplored. We investigated the evolution of mating behavior (latency to mating, mating probability and duration) in replicate populations of seed beetles Callosobruchus maculatus subjected to selection on life‐history (“Young” vs. “Old” reproduction) under contrasting regimes of sexual selection (“Monogamy” vs. “Polygamy”). Life‐history selection is predicted to favor delayed mating in “Old” females, but sexual conflict under polygamy can potentially retard adaptive life‐history evolution. We found that life‐history selection yielded the predicted changes in mating behavior, but sexual selection regime had no net effect. In within‐line crosses, populations selected for late reproduction showed equally reduced early‐life mating probability regardless of mating system. In between‐line crosses, however, the effect of life‐history selection on early‐life mating probability was stronger in polygamous lines than in monogamous ones. Thus, although mating system influenced male–female coevolution, removal of sexual selection did not affect the adaptive evolution of mating behavior. Importantly, our study shows that the interaction between sexual selection and life‐history selection can result in either increased or decreased reproductive divergence depending on the ecological context.     

Capuchin monkeys (Cebus apella) fail to show inequality aversion in a no-cost situation

Although humans show robust equality concerns across a variety of situations, there is ongoing debate regarding the extent to which any nonhuman species is inequality averse. In the current research, we test nonhuman primates' reactions to conspecifics receiving equal and unequal payoffs using a “no-cost” method in which subjects can respond to inequality without rejecting food. Specifically, we gave capuchin monkeys (Cebus apella) the opportunity to trade with one of two experimenters, each of whom offered the subject an identical reward, but had different histories of trading with the subject and a conspecific partner. An “equal” experimenter had previously given a conspecific the same reward that the subject had received, whereas the other experimenter was either an “advantageous trader” for the subject (giving the conspecific an inferior reward) or a “disadvantageous trader” for the subject (giving the conspecific a superior reward). By offering subjects a choice between experimenters, we removed several competing demands that may have masked the expression of robust equality preferences in previous studies. Even though there was no cost associated with expressing an equality preference, we found no evidence that capuchins differentiated between equal and unequal experimenters.     

Certification to ensure sustainable production of biofuels

Sustainability risks increase with rising biofuel production. Environmental, social and economic sustainability issues in agricultural production and conversion processes have become a major concern. External effects of biofuel production are not covered by a market mechanism. Therefore, an instrument to address the most pressing sustainability issues of biofuel production is required. The article provides the outline of an implementable certification concept that was elaborated in a multi-stakeholder approach with companies and organizations from Europe, the Americas, and Asia. The approach chosen for certification is beneficial for stakeholders, is market based and does not hamper international trade. The proposed certification system is focused on the most pressing sustainability issues, such as conversion of high carbon density and high nature value land. “Major must” and “minor must” criteria have been developed to assess the sustainability. The certification itself should occur through a compact and cost-effective system. A meta system approach will allow the use of already existing standards. Two separate certificates, one for sustainability of biomass production and one for greenhouse gas emissions, are proposed. The certificates are decoupled in a book and claim system from the biomass or biofuels traded and will be traded on a market place. The general concept of this certification system for biomass and biofuels has been discussed intensively with industry and trade companies and with public sector organizations and nongovernmental organizations. The practical feasibility should be tested in a pilot phase with co-operation of the stakeholders who are already involved.     

Analyzing the change in long-term information provision on cat management around a world natural heritage site

Providing accurate long-term information is essential in enhancing invasive species management. The management of invasive species—for example, outdoor cats—depends on human behavior and requires cooperation among stakeholders. Previous studies have evaluated stakeholders’ attitudes concerning invasive species, however, far too little attention has been paid to long-term information provisions. This study analyzes the information on cats in the Ogasawara Islands, a World Natural Heritage Site in Japan. We used monthly newsletters published by the local government for 21 years, which contain 150 articles about cats. We then applied content analysis to the data to assess both the frequency of keywords and co-occurrence network of words in order to understand the trends in keywords’ appearances and changing contexts. We categorized the data into three periods of seven years each, and found distinct differences. Results showed that information on cat management has gradually changed, as policies have changed. In the first period, there were three co-occurrence networks, which focused on capturing outdoor cats, proper keeping of pet cats, and veterinary care. During the second period, there were two networks, which focused on cat and World Natural Heritage Site management. During the third period, all keywords were connected into one network that included the words “outdoor cat,” “pet,” and “World Natural Heritage Site.” The changes imply that contents of information have shifted from pest management to ecosystem management. Visualizing how this information is provided over the long-term can remind stakeholders of previous communication efforts and enhance their cooperation on future conservation.     

Logical fallacies and invasion biology

Leading invasion biologists sometimes dismiss critics and criticisms of their field by invoking “the straw man” fallacy. Critics of invasion biology are also labelled as a small group of “naysayers” or “contrarians”, who are sometimes engaging in “science denialism”. Such unfortunate labels can be seen as a way to possibly suppress legitimate debates and dismiss or minimize reasonable concerns about some aspects of invasion biology, including the uncertainties about the geographic origins and complex environmental impacts of species, and the control programs against species perceived as “invasive”. In assessing the quality of the debate in this area, we examine the validity of the use of various strategies, including the “straw man” concept, and explore a range of potential logical fallacies present in some recent prominent discussions about invasion biology and so-called “invasive” species. The goal is to add some clarity to the concepts involved, point out some problematic issues, and improve the quality of the debates as the discussions move forward.     

Being a burden to others and wishes to die: The importance of the sociopolitical context

All articles in May 2019’s special issue of Bioethics offer profound insights into the issue of “being a burden to others” in relation to wishes to die, which are highly relevant for ethical debates about end-of-life care and physician-assisted dying. In this reply, we wish to stress the importance of acknowledging and analyzing the sociopolitical context of the phenomenon “being a burden” in relation to wishes to die and we will show how this analysis could benefit from a care ethical approach. As discussions in care ethics have made clear, caring practices are both social and political practices. An empirical and ethical analysis of “being a burden” therefore needs to take institutional and societal norms and structures into account, in addition to first-person experiences and concepts such as caring needs, relational autonomy, and interdependency. Besides the relevance of the sociopolitical context for the phenomenon “being a burden” as such, the sociopolitical context also seems relevant for the investigation of the phenomenon, which we will illustrate by reflecting on “being a burden” in relation to the practice of physician-assisted dying in the Netherlands.     

Navigating conflicts of justice in the use of race and ethnicity in precision medicine

Given the sordid history of injustices linking genetics to race and ethnicity, considerations of justice are central to ensuring the responsible development of precision medicine programmes around the world. While considerations of justice may be in tension with other areas of concern, such as scientific value or privacy, there are also tensions between different aspects of justice. This paper focuses on three particular aspects of justice relevant to this precision medicine: social justice, distributive justice and human rights. We describe the implications of each for the use of race and ethnicity in precision medicine, and also how they intersect and potentially conflict with each another. By attending to these intersections, we aim to enrich and add nuance to debates over how best to proceed with precision medicine initiatives.     

“Participating means accepting”: debating and contesting synthetic biology

This article analyses opposition to public debates. In doing so, the article builds upon the tradition of analyzing controversies by symmetrically describing the advocates and the opponents of public debates. First, the public debates on synthetic biology will be placed in their wider political and institutional context. The call for a “serene” debate by the French public authorities will be retraced and its genealogy vis-à-vis previous controversies (i.e. on genetically modified organisms (GMOs) and nanotechnology) will be elucidated. The article then describes how the group Pièces et main d’?uvre (PMO) obstructed a public debate on synthetic biology, an obstruction that will be analyzed by mobilizing and extending the notion of divisible versus indivisible conflicts. But the article will also move beyond the symmetrical analysis of a controversy by discussing one of the criticisms raised by PMO, that some researchers are “sociologists of acceptability.” The notions of divisibility, indivisibility and what I call “inversibility” will be used to reflect upon the positionality of social scientists and to offer a constructive view for a sociology of acceptability.     

Universal common ancestry,LUCA, and the Tree of Life: three distinct hypotheses about the evolution of life

Common ancestry is a central feature of the theory of evolution, yet it is not clear what “common ancestry” actually means; nor is it clear how it is related to other terms such as “the Tree of Life” and “the last universal common ancestor”. I argue these terms describe three distinct hypotheses ordered in a logical way: that there is a Tree of Life is a claim about the pattern of evolutionary history, that there is a last universal common ancestor is an ontological claim about the existence of an entity of a specific kind, and that there is universal common ancestry is a claim about a causal pattern in the history of life. With these generalizations in mind, I argue that the existence of a Tree of Life entails a last universal common ancestor, which would entail universal common ancestry, but neither of the converse entailments hold. This allows us to make sense of the debates surrounding the Tree, as well as our lack of knowledge about the last universal common ancestor, while still maintaining the uncontroversial truth of universal common ancestry.     

Professionalization as a governance strategy for synthetic biology

This article considers professionalization as a governance strategy for synthetic biology, reporting on social science interviews done with scientists, science journal editors, members of science advisory boards and authors of nongovernmental policy reports on synthetic biology. After summarizing their observations about the potential advantages and disadvantages of the professionalization of synthetic biology, we analyze professionalization as a strategy that overcomes dichotomies found in the current debates about synthetic biology governance, specifically “top down” versus “bottom up” governance and scientific fact versus public values. Professionalization combines community and state, fact and value. Like all governance options, professionalization has limitations, particularly regarding war and peace. It is best conceptualized as potentially part of a wider range of governance mechanisms working in concert: a “web of prevention”.     

OLIGONUCLEOTIDES AS CODING MOLECULES IN AN ANTI-COUNTERFEITING SYSTEM

Due to the growing numbers of counterfeited products on the world market, there is a huge demand for new and forgery-proof marking systems. We developed a unique system using “molecular beacons” with well adapted thermodynamic parameters. This marking system consists of the three components: DNA tag (a label or directly printing), detection pen (contains the “molecular beacon” solution), and DNA-scanner (reads the specific signal triggered by the detection pen even at daylight). The vast coding capacity of DNA combined with the highly specific signal offers a degree of security that is unmatched by conventional identification technologies.     

<Emphasis Type="Bold">Ethics and Epistemology of Big Data</Emphasis>

In this Symposium on the Ethics and Epistemology of Big Data, we present four perspectives on the ways in which the rapid growth in size of research databanks—i.e. their shift into the realm of “big data”—has changed their moral, socio-political, and epistemic status. While there is clearly something different about “big data” databanks, we encourage readers to place the arguments presented in this Symposium in the context of longstanding debates about the ethics, politics, and epistemology of biobank, database, genetic, and epidemiological research.     

Linking Industrial Ecology with Business Strategy: Creating Value for Green Product Design

As organizations practice environmental design, some discover green design positively impacts business performance. This article demonstrates how an organization can employ existing design methods and tools with the Kano technique to craft an environmental product design strategy that enhances its business strategy. These tools expand the toolbox of the industrial ecologist and enable the link between green design and business improvement. The Kano technique was developed in the 1980s to facilitate design of innovative products. We also introduce terminology and concepts such as “voices of the environment,”“environmental knowledge management,”“environmental profile,” and “environmental product attribute” in order to bridge the gap between industrial ecology and business concerns. To demonstrate how an organization can find the synergy between business value and environmental value, this article describes three activities and their corresponding tools and exhibits their use with industry examples. First, we present techniques by which designers can identify and prioritize customers and stakeholders who voice both environmental and business concerns. Second, we describe how voice‐of‐the‐customer translation techniques can be used to efficiently collect and translate data from these customers and stakeholders into critical environmental product and service attributes. Third, we discuss how the Kano technique can be used to connect green design to business strategy by making visible the variety of stakeholder and customer perceptions of these critical environmental attributes. Examples then demonstrate how those perceptions suggest appropriate approaches for integrating the critical environmental attributes into product and business strategy. Finally, we provide examples based on work done with General Electric Medical Systems (GEMS) to illustrate the design of products that improve environmental performance while adding greater perceived value for numerous customers along material‐flow value chains.     

The Local and Global State of Theater Education Research and Policy

The United States and much of the world is struggling with what “education” and being “educated” mean. Daily media are replete with debates on issues ranging from gender and class rights to the ideological and practical purpose of education. Prominent among these debates are discussions about whether education should be geared toward vocational purposes and employability or toward the creation of engaged, informed, and intellectually aware citizens. In this article we problematize the role and limitations of current research on drama and theater in and as education. To do this, we first share a sampling of the current state of research in this arts area. We then articulate the role this diverse range of research methodologies and foci play in shaping national and global educational policy.     

Health‐related Research Ethics and Social Value: Antibiotic Resistance Intervention Research and Pragmatic Risks

We consider the implications for the ethical evaluation of research programs of two fundamental changes in the revised research ethical guideline of the Council for International Organizations of Medical Sciences. The first is the extension of scope that follows from exchanging “biomedical” for “health‐related” research, and the second is the new evaluative basis of “social value,” which implies new ethical requirements of research. We use the example of antibiotic resistance interventions to explore the need to consider the instances of what we term the pragmatic risks of such interventions to evaluate the social value of certain kinds of health‐related research. These (pragmatic) risks severely threaten the social value of interventions in every area where human and social responses significantly impact on their effectiveness. Thus, the social value of health‐related research needed to demonstrate its effectiveness depends on the extent and successful management of such risks. Research designed to take into account the management of pragmatic risks also gives rise to similar types of risks, and the potential for social value in light of those risks needs to be considered in ethical reviews based on the new guidelines. We argue that, to handle this new expanded task, the international system of research ethical review addressed by the guidelines needs institutional development.
