The three‐dimensional structure of DNA depends subtly on its sequence, and this property is used by the proteins that regulate gene expression to locate their target sequences. Despite the large body of experimental data that has been accumulated on the relationship between sequence and DNA structure, we still do not fully understand the molecular basis for these properties, nor can we predict a three‐dimensional structure from a given sequence. We have been using computer modelling to tackle these problems. Some of (...) our results and the implications for understanding the biological role of key sequences are discussed here. (shrink)

Thirty-two vegans were interviewed in order to examine the reasons for becoming vegan, the sustaining motivation to persist, the interpersonal and intrapersonal impact of the diet and associated practices, and the vegans’ assessment of omnivores’ eating practices. Interviews were analyzed using a model that diagrams the process of becoming vegan provided by McDonald . Participants reported strained professional and personal relationships as a result of their diet and beliefs. Vegan diets were associated with an increase in physical, eudaemonic, and spiritual (...) well-being. (shrink)

I will entertain and reject three arguments which putatively establish that the individuals produced through de-extinction ought to be the same species as the extinct population. Forms of these arguments have appeared previously in restoration ecology. The first is the weakest, the conceptual argument, that de-extinction will not be de-extinction if it does not re-create an extinct species. This is misguided as de-extinction technology is not unified by its aim to re-create extinct species but in its use of the remnants (...) of extinct populations as a resource. The second is the argument from authenticity; the populations produced by de-extinction technologies will be inauthentic if they are not of the extinct species and, therefore, will not be valuable. I argue authenticity is not required in conservation as the value of authenticity varies between people and cultures, and the novelty of de-extinct species will be equally desirable in many cases. The third argument is from retributive justice; we need the de-extinct population to have the same species identity as we owe a moral debt to the extinct population. I find the case for retributive justice unconvincing and argue that acting as if we have a duty to resurrect extinct species will result in a world with less species. Ultimately all the arguments that connect de-extinction technology to species identity fail, leaving us to consider a more complex calculus for the justification of de-extinction in conservation.

If ecological systems are functionally organised, they can possess functions or malfunctions. Natural function would provide justification for conservationists to act for the protection of current ecological arrangements and control the presence of populations that create ecosystem malfunctions. Invasive species are often thought to be malfunctional for ecosystems, so functional arrangement would provide an objective reason for their control. Unfortunately for this prospect, I argue no theory of function, which can support such normative conclusions, can be applied to large scale (...) ecosystems. Instead ecological systems have causal structure, with small clusters of populations achieving functional arrangement. This, however, does not leave us without reason to control invasive species. We can look at the causal arrangement of ecological systems for populations that support ecological features that we should preserve. Populations that play a causal role in reducing biodiversity should be controlled, because biodiversity is a good all prudent agents should want to preserve. (shrink)

Biodiversity is a key concept in the biological sciences. While it has its origin in conservation biology, it has become useful across multiple biological disciplines as a means to describe biological variation. It remains, however, unclear what particular biological units the concept refers to. There are currently multiple accounts of which biological features constitute biodiversity and how these are to be measured. In this paper, I draw from the species concept debate to argue for a set of desiderata for the (...) concept of “biodiversity” that is both principled and coheres with the concept’s use. Given these desiderata, this concept should be understood as referring to difference quantified in terms of the phylogenetic structure of lineages, also known as the ‘tree of life’. (shrink)

Eric Katz in Zombie Arguments defends the thesis authenticity is indispensable to conservation. I agree. However, I argue authenticity appears in degrees and can be reclaimed by populations through their continuing evolutionary responses to the world. This means that interventions that diminish the value of a population through reducing their authenticity can be permitted in limited cases. When our actions retain the remaining authentic features in a threatened population we should allow such a diminishment as authenticity can be reclaimed in (...) time. (shrink)

The question of whether there are laws of nature in ecology has developed substantially in the last 20 years. Many have attempted to rehabilitate ecology’s lawlike status through establishing that ecology possesses laws that robustly appear across many different ecological systems. I argue that there is still something missing, which explains why so many have been skeptical of ecology’s lawlike status. Community ecology has struggled to establish what I call a General Unificatory Theory. The lack of a GUT causes problems (...) for explanation as there are no guidelines for how to integrate the lower-level mathematical and causal models into a larger theory of how ecological assemblages are formed. I turn to a promising modern attempt to provide a unified higher-level explanation in ecology, presented by ecologist Mark Vellend, and advocate for philosophical engagement with its prospects for aiding ecological explanation. (shrink)

Ecological communities are seldom, if ever, biological individuals. They lack causal boundaries as the populations that constitute communities are not congruent and rarely have persistent functional roles regulating the communities’ higher-level properties. Instead we should represent ecological communities indexically, by identifying ecological communities via the network of weak causal interactions between populations that unfurl from a starting set of populations. This precisification of ecological communities helps identify how community properties remain invariant, and why they have robust characteristics. This respects the (...) diversity and aggregational nature of these complex systems while still vindicating them as units worthy of investigation. (shrink)

The introduction of new genetic material into wild populations, using novel biotechnology, has the potential to fortify populations against existential threats, and, controversially, create wild genetically modified populations. The introduction of new genetic variation into populations, which will have an ongoing future in areas of conservation interest, complicates long-held values in conservation science and park management. I discuss and problematize, in light of genetic intervention, what I consider the three core goals of conservation science: biodiversity, ecosystem services, and wilderness. This (...) uneasy relationship, however, does not forgo the use of such interventions. I argue there is a case for the application of this technology within some interpretations of the moral frameworks of wilderness and biodiversity, despite apparent conflict between these values and the technology, and the possibility that this technology's use displays some limitations of the ecosystem services framework. Ultimately, the advent of biotechnology assisted restoration highlights the need for us to reevaluate our ethical concepts of conservation at times of global environmental and technological change.

All known chimpanzee populations have been observed to hunt small mammals for meat. Detailed observations have shown, however, that hunting strategies differ considerably between populations, with some merely collecting prey that happens to pass by while others hunt in coordinated groups to chase fast-moving prey. Of all known populations, Taï chimpanzees exhibit the highest level of cooperation when hunting. Some of the group hunting roles require elaborate coordination with other hunters as well as precise anticipation of the movements of the (...) prey. The meat-sharing rules observed in this community guarantee the largest share of the meat to hunters who perform the most important roles leading to a capture. The learning time of such hunting roles is sometimes especially long. Taï chimpanzee males begin hunting monkeys at about age 10. The hunters’ progress in learning the more sophisticated hunting roles is clearly correlated with age; only after 20 years of practice are they able to perform them reliably. This lengthy learning period has also been shown in some hunter-gatherer societies and confirms the special challenge that hunting represents. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Gandhi's Hope: Learning from Other Religions as a Path to PeaceChristopher Key ChappleGandhi's Hope: Learning from Other Religions as a Path to Peace. By Jay McDaniel. Maryknoll, NY: Orbis Books, 2005. 134 + viii pp.This book by prominent Protestant theologian Jay McDaniel suggests that Mahatma Gandhi challenged the modern world by publicly revealing that which he learned from other faith traditions and advocating this path as a way (...) for intercultural understanding. The wisdom of Gandhi holds special poignancy today, when the processes of globalization and migration have placed followers of different faiths in closer proximity than can be remembered in the past five hundred years.Jay McDaniel writes with crisp clarity and organizes his insights into bite-sized pieces. He lays out five challenges that face all the world's faiths: compassion, self-criticism, simple living, ecological awareness, and welcoming religious diversity. In approaching this decidedly postmodern list of issues, McDaniel draws from two primary resources: the experiences shared by his students at Hendrix College and the writings of Alfred North Whitehead. Along the way, he invokes the Buddhist teacher and leader Thich Nhat Hanh and several progressive Catholics, including Sister Joan Chittester and theologians Hans Küng and Paul Knitter.Continuing with a style developed in his earlier books, McDaniel latches onto a [End Page 237] metaphor and extends it to illustrate his central point—in this case, the value of diversity. In past books, he has used the image of the hunter and the hunted to underscore the need to respect animals. In Gandhi's Hope, the metaphor he employs is that of a jazz concert, with all different manner of instruments pooling their resources to create a tapestry of diverse yet harmonious music.Although the title of the book may seem to indicate that Gandhi will serve as thefocus, in fact, Whitehead anchors McDaniel's approach. Through an updated approach to Whitehead, McDaniel seeks to answer the questions regarding diversity and compassion that he has posed. He suggests that an experience of concrescence will result in the sort of heightened awareness needed to increase one's conscience and to make the ethical changes needed to respond to the current state of the world. McDaniel identifies twelve "planks" that will usher Whitehead's vision into the contemporary world. These twelve aspects seem also to be heavily influenced by McDaniel's own encounter with Buddhism: interdependence, impermanence, indeterminism, mind/matter, deep listening, value, God, creativity, persuasive power, divine empathy, many forms of salvation, and life after death. These broad categories embrace key notions found in all religious traditions. Some traditions emphasize certain aspects more than others. Buddhists cleave to impermanence and Jews to establishing a covenant with God, but Jews also recognize that all things will pass, and Buddhists revere their great teacher and many strive to emulate his experience through techniques akin to those who worship God.In order for religious traditions to maintain their urgency and relevance, McDaniel suggests that they must respond actively to the looming threat of environmental degradation. Consumer culture drives people into a state of indifference about natural resources, and arrogance prevents people from taking an interest in the life patterns and cultures of others. These tendencies lie at the root of the world's troubles. McDaniel suggests that process theology can remedy these ills by calling people into a state of compassion and can help guide people toward adopting thoughtful self-criticism, to living a more simple life, to recognizing the importance of other living beings and ecosystems, and to celebrating diversity of cultures. Echoing a refrain long associated with process thought, McDaniel writes "the universe is a creative and creating process of interdependent events, lured by but not controlled by God, such that the future is not yet decided, not even by God" (p. 71). To the extent that religions sustain themselves by reinforcing separateness and promoting a narrow cultural identity and/or an unthinking fundamentalism, they can be an impediment to peace, which, for McDaniel, is an important goal of the world's religions.When attempting to theologize about ultimate matters, McDaniel posits "four faces of the sacred," which he lists as the Abyss...

Proponents of the standard evolutionary biology paradigm explain human “altruism” in terms of either nepotism or strict reciprocity. On that basis our underlying nature is reduced to a function of inclusive fitness: human nature has to be totally selfish or nepotistic. Proposed here are three possible paths to giving costly aid to nonrelatives, paths that are controversial because they involve assumed pleiotropic effects or group selection. One path is pleiotropic subsidies that help to extend nepotistic helping behavior from close family (...) to nonrelatives. Another is “warfare”—if and only if warfare recurred in the Paleolithic. The third and most plausible hypothesis is based on the morally based egalitarian syndrome of prehistoric hunter-gatherers, which reduced phenotypic variation at the within-group level, increased it at the between-group level, and drastically curtailed the advantages of free riders. In an analysis consistent with the fundamental tenets of evolutionary biology, these three paths are evaluated as explanations for the evolutionary development of a rather complicated human social nature.

Children may be viewed as public goods whereby both parents receive equal genetic benefits yet one parent often invests more heavily than the other. We introduce a microeconomic framework for understanding household investment decisions to address questions concerning conflicts of interest over types and amount of work effort among married men and women. Although gains and costs of marriage may not be spread equally among marriage partners, marriage is still a favorable, efficient outcome under a wide range of conditions. This (...) bioeconomic framework subsumes both cooperative and conflictive views on the sexual division of labor. We test hypotheses concerning marriage markets, assortative mating, and men’s labor motivations among Tsimane forager-horticulturalists of Bolivia and find that: (1) men and women both value work effort in marital partners, (2) marital labor contributions are complementary, (3) work effort is correlated between spouses, (4) total production is correlated with total reproduction, and (5) better hunters have higher fitness gains within marital unions.

Although populism is an ideologically fluid political vehicle, it is not one that is intrinsically anti-business. Indeed, different varieties of populist parties may encourage business activity for utilitarian ends, but with their own ideas on what businesses should be doing. This reality implies that initiatives not related to national greatness or priorities as defined by the populist leadership may be viewed as redundant. Key among such initiatives would be corporate social responsibility (CSR). In a populist environment, it is possible that (...) firms may divert resources away from broad-based CSR under pressure from populist governments. This article explores the relationship between populist governance and CSR with an econometric examination of over a thousand firms in 13 countries under both pro- and anti-business populist governments at varying times from 2012 to 2020. Using dynamic panel data methods, we find strong evidence that firms substitute away significantly from CSR under populism. This effect grows significantly larger under anti-business populists.

Professional engineers are under increasing pressure to practice in an environmentally sensitive way. To prepare engineers for this new reality, changes in engineering education are needed. For example, engineering hydrology has traditionally been taught with an emphasis on the interpretation of numerical data bout rainfall and runoff in watersheds. However, to do environmentally sensitive hydrology work, it is necessary to also understand the life forms that share the watershed. In 1997, a project was undertaken in the Department of Civil Engineering (...) at the University of Toronto to enhance an introductory hydrology course by adding information about how hydrological phenomena affect fish. Through carefully structured assignments and exam questions, an assessment was made of the effectiveness of the enhancements in increasing students’ awareness of the life context of hydrology. The project has resulted in a commitment to increased environmental information in the hydrology curriculum, and the implementation of an assessment process for all students, to monitor changes in their environmental knowledge and attitudes. It has also raised questions about ultimate objectives in engineering education. (shrink)

This paper offers a new argument against raising and killing sentient non-human animals for food. It is immoral to non-lethally impair sentient non-human animals for pleasure, and since raising and killing sentient animals for gustatory pleasure impairs them to a much greater degree, it also is wrong. This is because of the impairment principle: if it is immoral to impair an organism to some degree, then, ceteris paribus, it is immoral to impair it to a higher degree. This argument is (...) structurally analogous to Perry Hendricks’s impairment argument for the immorality of abortion. However, the argument is more defensible applied to the raising and killing of sentient nonhuman animals for food because of the sentience of the non-human animals involved. I explain how the argument is distinct from other pro-vegan, pro-vegetarian arguments. (shrink)

ABSTRACTEmotions influence cognitive processes involved in memory. While some research has suggested that cognitive scope is determined by affective valence, recent models of emotion–cognition interactions suggest that motivational intensity, rather than valence, influences these processes. The present research was designed to clarify how negative affects differing in motivational intensity impact memory for centrally or peripherally presented information. Experiments 1 & 2 found that, relative to a neutral condition, high intensity negative affect enhances memory for centrally presented information. Experiment 3 replicated (...) this effect using another high intensity negative affect. Experiment 4 extended this by finding that, relative to a neutral condition, low intensity negative affect enhanced memory for peripherally presented information. Finally, in Experiment 5, the effects of sadness and threat on scope of memory were directly compared, finding that threat narrowed scope of... (shrink)

Workers often have a complex relationship with the technologies they use in the workoplace, and many influences can affect that relationship. This is well demonstrated in the story of unionized painters who, at the turn of this century, were sufferingfrom occupational lead poisoning because the paints of the day used lead as their primary pigment. At the beginning of the study period, the painters were fairly passive about the disease, having accepted it as a hazard of the job. By the (...) middle of the 1920's, however, the painters' union was fighting aggressively to remove lead from their work environments and to make employers take some responsiblilty for work-related health care needs. No single event or person brought this change about. Instead, it was the coalescence of several influences that convinced the painters that occupational lead poisoning was something they should fight against. (shrink)

Theory and practice, reason and revelation, ancients and moderns are the key themes running through the eighteen studies of the literature of political philosophy in Reason's Inquisition.

Marleen Eijkholt presents a new argument in healthcare ethics, the false hope harms (FHH) argument. In brief, false hope promotes a host of individual harms (e.g., financial, physical, and psychological harms) and system‐level harms (e.g., distrust of medical practitioners, increased complexity of care and the associated costs), all of which provide reason for healthcare providers to stop promoting false hope in medicine. The goal of this paper is to show that the FHH argument is unsuccessful.

I consider the question of how literally one can construe the “gauge argument,” which is the canonical means of understanding the putatively central import of local gauge symmetry principles for fundamental physics. As I argue, the gauge argument must be afforded a heuristic reading. Claims to the effect that the argument reflects a deep “logic of nature” must, for numerous reasons I discuss, be taken with a grain of salt.

Discussions of monotheism often consider its bigotry toward other gods as a source of conflict, or emphasize its universality as a source of peaceful tolerance. Both approaches, however, ignore the combined danger and liberation in monotheism's 'intolerance.' In this volume, Christopher Haw reframes this important argument. He demonstrates the value of rejecting paradigms of inclusivity in favor of an agonistic pluralism and intolerance of absolutism. Haw proposes a model that retains liberal, pluralistic principles while acknowledging their limitations, and he (...) relates them to theologies latent in political ideas. His volume offers a nuanced, evolutionary, and historical understanding of the biblical tradition's emergence and its political consequences with respect to violence. It suggests how we can mediate impasses between liberal and conservative views in culture wars; between liberal inclusivity and conservative decisionism; and, on the religious front, between apologetics for exclusive monotheism and critiques of its intolerance.

The present study examines section five of Poroi and Xenophon’s proposal to restore the reputation of Athens. After outlining his plan for ‘justly’ supplying the dēmos with sufficient sustenance in Poroi 1-4, section 5 addresses the desire to regain hegemony after Athens had lost the Social War. Xenophon does not adopt an anti-imperialist stance; instead he seeks to re-align imperial aspirations with Athenian ideals and earlier paradigms for securing hegemony. Xenophon’s ideas in Poroi are contextualized with consideration for his ‘Socratic’ (...) distinction between tyranny and kingship, as well as his wider advice for ruling well. It is shown that his proposals for securing the consent of the allies reiterates ideas that Xenophon outlines across his corpus, especially Hiero and Cyropaedia. In Poroi Xenophon therefore applies his political thought in an attempt to re-direct Athenian ambitions away from policies that prompted charges of being a ‘tyrant polis’ and towards ‘legitimate rule’.

In a familiar passage from Plato's Euthyphro, Socrates points to a contrast between "matters of difference that cause hatred and anger," and matters where agreement is reached by seemingly rational means. Where a dispute concerns number, size or weight, we arrive at a decision by counting or measuring. But there are matters of disagreement where such convergence is not to be expected: "the just and the unjust, the beautiful and the ugly, the good and the bad" notorious among them. Socrates's (...) point, in drawing what a modern reader might take to be a contrast between facts and values, is not so easily understood. The Euthyphro passage elicits a concern-call it a concern about "objectivity"-which is often addressed in a characteristically narrow way. How we approach a given concern depends on how we articulate that concern, and this is what I propose to consider here. (shrink)

"Mobile Lifeworlds illustrates how the imaginaries and ideals of Western travellers, especially those of untouched nature and spiritual enlightenment, are consistent with media representations of the Himalayan region, romanticism and modernity at large. Blending tourism and pilgrimage, travel across Nepal, Tibet, Bhutan, and Northern India is often inspired and oriented by a search for authenticity, adventure and Otherness. Such valued ideals are shown, however, to be contested by the very forces and configurations that enable global mobility. The role ubiquitous media (...) and mobile technologies now play in framing travel experiences are explored, revealing a situation in which actors are neither here nor there, but increasingly are 'inter-placed' across planetary landscapes. Beyond institutionalised religious contexts and the visiting of sacred sites, the author shows how a secular religiosity manifests in practical, bodily encounters with foreign environments. This book is unique in that it draws on a dynamic and innovative set of disciplinary and theoretical perspectives, especially phenomenology, the mobilities paradigm and philosophical anthropology. The volume breaks fresh ground in pilgrimage, tourism and travel studies by unfolding the complex relationships between the virtual, imaginary and corporeal dynamics of contemporary mobile lifeworlds"--From publisher's website.

The year 2019 witnessed the 20th Jubileum of the Växjö conference series on quantum foundations and probability in physics. This has been the longest running series of conferences on the subject in history. Many old and new friendships were forged at Linnaeus University and the beautiful surrounding lakes of Småland, where once yearly everyone gathers to renew the debate and report their latest progress. 2019 also represents the Porcelain Anniversary—18 years—of the point of view on quantum theory known as QBism. (...) In this regard, the 2001 meeting in the series was pivotal in more ways than one. Not only did it instigate Fuchs’s break [1] from the earlier (Jaynes style) “objective Bayesianism” and neo-Copenhagen thinking of Caves et al. [2], but it was the first meeting at an international scale to indicate that the quantum information revolution might have something genuine to contribute to quantum foundational thought. That meeting set the pace far beyond Växjö by the participation of a number of luminaries of quantum information: The late Asher Peres, Daniel Greenberger, David Mermin, Herbert Bernstein, Carlton Caves, Rüdiger Schack, Richard Jozsa, Benjamin Schumacher, and John Smolin. One could almost hear a battle cry echo from the woods, “Quantum foundations from quantum information or die!” The foundations debate had turned so stale by the time, it would surely die without an influx of new thinking.

The ethical theory espoused by a philosopher is often dominated by certain implicit epistemological assumptions. These “ways of knowing” may in turn be dominated by personality preferences that give rise to certain preferred worldviews that undergird various philosophies. Such preferred worldviews are seen in We believe positions, stated or unstated. The meaning of these claims about the interconnections of unexamined assumptions and their philosophical implications may be seen through an example. This paper will examine certain crucial aspects of the thought (...) of John Doris, who promotes a form of situationist ethics. This example is intended to be suggestive rather than conclusive. It points to the need for an openness to other epistemological assumptions that might permit a more comprehensive appreciation of what moral agency involves, beyond what arises from the restricted methods of analytical philosophy and a positivist worldview. There have been other efforts to meet the situationist challenge to classical Aristotelian ethics, yet surprisingly little attention has been given to the role of implicit epistemologies and unexamined psychologies. This paper offers a critical examination of these prior We believe positions. (shrink)

This unique interpretation of Alfarabi's thought stresses the ways in which the tenth-century Arab philosopher self-consciously broke the metaphysical tradition that began with Plato. By examining Alfarabi's work as more than an extension or continuation of Greek philosophy, Colmo rethinks what medieval philosophy is and challenges almost universal assumptions about the origins of modernity.
