Language’s intentional nature has been highlighted as a crucial feature distinguishing it from other communication systems. Specifically, language is often thought to depend on highly structured intentional action and mutual mindreading by a communicator and recipient. Whilst similar abilities in animals can shed light on the evolution of intentionality, they remain challenging to detect unambiguously. We revisit animal intentional communication and suggest that progress in identifying analogous capacities has been complicated by (i) the assumption that intentional (that is, voluntary) production (...) of communicative acts requires mental-state attribution, and (ii) variation in approaches investigating communication across sensory modalities. To move forward, we argue that a framework fusing research across modalities and species is required. We structure intentional communication into a series of requirements, each of which can be operationalised, investigated empirically, and must be met for purposive, intentionally communicative acts to be demonstrated. Our unified approach helps elucidate the distribution of animal intentional communication and subsequently serves to clarify what is meant by attributions of intentional communication in animals and humans.

The proposed national PrEP program would serve people who are uninsured as well as those enrolled in Medicaid. In this article, the authors propose a set of recommendations for the proposed program’s implementers as well as state Medicaid agencies and Medicaid managed care organizations to ensure PrEP access for people enrolled in Medicaid, addressing gaps without undermining the important role of the Medicaid program in covering and promoting PrEP.

En las últimas décadas del siglo XVI, se hallaron en la ciudad de Granada una serie de documentos falsificados y unas supuestas reliquias. Este artículo examina cómo al Sacromonte, el sitio de los hallazgos más destacados, fue convertido en el paisaje simbólico de la identidad espiritual granadina. Las reliquias y las circunstancias milagrosas con las cuales estaban relacionadas efectuaron una reconfiguración de la gaografía sagrada de la ciudad, transformando un sitio sagrado de los moriscos en un centro de la santidad (...) cristiana y un símbolo principal de los aspectos religiosos de la identidad cívica de la Granada moderna. Este artículo también considera cómo este paisaje sagrado fue expresado gráficamente por medio de representaciones cartográficas de Granada. (shrink)

Research is crucial to advancing knowledge about dementia, yet the burden of the disease currently outpaces research activity. Research often excludes people with dementia and other cognitive impairments because researchers and ethics committees are concerned about issues related to capacity, consent, and substitute decision-making. In Australia, participation in research by people with cognitive impairment is governed by a national ethics statement and a patchwork of state and territorial laws that have widely varying rules. We contend that this legislative variation precludes (...) a consistent approach to research governance and participation and hinders research that seeks to include people with impaired capacity. In this paper, we present key ethical principles, provide a comprehensive review of applicable legal rules in Australian states and territories, and highlight significant differences and ambiguities. Our analysis includes recommendations for reform to improve clarity and consistency in the law and reduce barriers that may exclude persons with dementia from participating in ethically approved research. Our recommendations seek to advance the national decision-making principles recommended by the Australian Law Reform Commission, which emphasize the rights of all adults to make their own decisions and for those with impaired capacity to have access to appropriate supports to help them make decisions that affect their lives.

Advocates of dialogic communication have promoted two-way symmetrical communication as the most effective and ethical model for public relations. This article uses John Durham Peters's critique of dialogic communication to reconsider this infatuation with dialogue. In this article, we argue that dialogue's potential for selectivity and tyranny poses moral problems for public relations. Dialogue's emphasis on reciprocal communication also saddles public relations with ethically questionable quid pro quo relationships. We contend that dissemination can be more just than dialogue because it (...) demands more integrity of the source and recognizes the freedom and individuality of the source. The type of communication, such as dialogue or dissemination, is less important than the mutual discovery of truth. Reconciliation, a new model of public relations, is proposed as an alternative to pure dialogue. Reconciliation recognizes and values individuality and differences, and integrity is no longer sacrificed at the altar of agreement. (shrink)

Existing research has examined if undergraduate factors influence chemistry and physics, or physical science, doctoral degree entry and whether variables during PhD programs associate with graduation. Yet research on the transition from bachelor’s degree to doctoral degree entry (i.e., PhD entry in less than 6 months, attainment of a master’s degree prior to doctoral degree entry, or working in a science-related job for more than a year prior to doctoral degree entry) on PhD degree graduation remains scarce. Our study examines (...) the transition from bachelor’s to doctoral degrees to see if experiences therein associate with female PhD graduation, after doctoral degree enrollment. Our logistic regression analysis, of female chemistry and physics doctorates (n = 867), indicated that attainment of a master’s degree did not change the likelihood of graduation, when compared to direct entry into physical science doctoral programs. Meanwhile working in a science-related job for a year or more is associated with a significantly lower likelihood of physical science doctoral graduation when compared to women who entered directly into PhD programs or received a master’s degree prior to enrollment.

BackgroundThough sobriety in young people is on the rise, students who drink little or no alcohol may experience social exclusion at University, impacting well-being. We aim to understand the social experiences of United Kingdom undergraduate students who drink little or no alcohol.MethodsA mixed-methods study using semi-structured, one-to-one interviews and the 24-Item Social Provisions Scale and Flourishing Scale with 15 undergraduate students who drink little or no alcohol. Descriptive statistics are presented for quantitative data and thematic analysis for qualitative.ResultsEight main themes (...) and four subthemes were generated from thematic analysis summarised in two sections ‘views of drinkers from non-drinkers’ and ‘how peer pressure feels and how people deal with it.’ The initial transition to University represented a challenge, where participants struggled to find their ‘true’ friends. However, students generally had high levels of social provision, well-being and enjoyed close friendships with fewer casual acquaintances. All students experienced some kind of peer pressure and developed coping strategies when in social situations involving alcohol. Fear of missing out on the ‘typical’ University experience heightened self-imposed expectations to drink. Despite participants acknowledging their counter-normative behaviour, some felt they were subject to stigmatisation by drinkers, doubting their non-drinker status, causing feelings of exclusion or being ‘boring.’ Their desire to ‘be like everyone else’ exposed some insight into the negative stereotypes of sobriety, including frustration behind alcohol’s status elevation.ConclusionStudents adopt strategies to minimise peer pressure and to fit in. Future research should interrogate drinkers’ perceptions of their sober peers to deepen understanding, better break down ‘us and them,’ and mitigate future expectations within the University drinking culture.

Everybody negotiates. But not everybody negotiates ethically. One driver of unethical negotiation behavior is power. Yet, we still haven’t discovered the principalmoderating and mediating influences between power and ethical negotiation behavior. In this pair of experimental studies we’re interested in finding out how resilience and moral identity affect an individual’s ethical behavior in both simple and complex negotiations when primed for power.

Previous research suggests that exposure to nature may reduce delay discounting and thereby facilitate healthier dietary intake. This pre-registered study examined the impact of online exposure to images of natural scenes on delay discounting and food preferences. It was predicted that exposure to images of natural scenes would be associated with: lower delay discounting; higher desirability for fruits and vegetables ; and delay discounting would mediate the effect of nature-image exposure on food desirability. Adult participants were recruited to an online (...) between-subjects experiment in which they viewed a timed sequence of six images either showing natural landscape scenes or urban scenes. They then completed measures of mood, delay discounting and rated their momentary desire to eat four fruits and vegetables, and four energy-dense foods. There was no statistically significant effect of experimental condition on delay discounting or food desirability. Bayes factors supported the null hypothesis for discounting, and energy-dense food desirability, but provided no strong evidence for either hypothesis for F&V desirability. These findings indicate that brief online exposure to images of nature does not affect momentary impulsivity or energy-dense food preference, whereas for preference for less-energy dense foods, the evidence was inconclusive.

There is a strong impetus in international agricultural development to close ‘gender gaps’ in agricultural productivity. The goal of empowering women is often framed as the solution to closing these gaps, stimulating the proliferation of new indicators and instruments for the targeting, measurement, and tracking of programmatic goals in research for agricultural development. Despite these advances, current measurements and indices remain too simplified in terms of unit and scope of analysis, as well as being fundamentally flawed in how they aim (...) to capture the relevance of ‘gender’ in diverse local contexts. We propose that the impulse to apply exogenously defined and weakly validated ‘women’s empowerment’ measures to diverse local contexts risks prioritizing practical expedience over scientific accuracy and societal relevance. Furthermore, the application of such measures risks creating the impression that programmatic “gender targets” are being achieved, while simultaneously undermining substantive gender transformative goals. The authors conclude that a different methodological approach grounded in participatory and qualitative methods is needed to create more meaningful metrics for assessing progress towards women’s empowerment.

Group decisions raise a number of substantial philosophical and methodological issues. We focus on the goal of the group decision exercise itself. We ask: What should be counted as a good group decision-making result? The right decision might not be accessible to, or please, any of the group members. Conversely, a popular decision can fail to be the correct decision. In this paper we discuss what it means for a decision to be "right" and what components are required in a (...) decision process to produce happy decision-makers. Importantly, we discuss how "right" decisions can produce happy decision-makers, or rather, the conditions under which happy decision-makers and right decisions coincide. In a large range of contexts, we argue for the adoption of formal consensus models to assist in the group decision-making process. In particular, we advocate the formal consensus convergence model of Lehrer and Wagner (1981), because a strong case can be made as to why the underlying algorithm produces a result that should make each of the experts in a group happy. Arguably, this model facilitates true consensus, where the group choice is effectively each person's individual choice. We analyse Lehrer and Wagner's algorithm for reaching consensus on group probabilities/utilities in the context of complex decision-making for conservation biology. While many conservation decisions are driven by a search for objective utility/probability distributions (regarding extinction risks of species and the like), other components of conservation management primarily concern the interests of stakeholders. We conclude with cautionary notes on mandating consensus in decision scenarios for which no fact of the matter exists. For such decision settings alternative types of social choice methods are more appropriate. (shrink)

In Western Kenya, smallholder dairy production is becoming incrementally commercialized through the commodification and sale of milk through formal market channels. While commercialization is often construed as a way to boost rural livelihoods through increased income from milk, emerging evidence suggests that married women are not directly benefiting from formal milk market participation. This critical issue of gender power imbalance has been framed by development interventions in economic efficiency and social justice perspectives, but thus far interventions in the sector have (...) not addressed how underlying social-market mechanisms embedded in gendered ideology influence smallholder engagement in dairy commercialization. Drawing on feminist theories of power and social embeddedness, this study investigates how gendered power relationships materialize and influence formal milk marketing engagement and practices in Western Kenya. Facilitated discussion groups with smallholder farmers revealed the gendered ideologies and norms that ascribe masculinized meaning to cattle, milk, and commercial enterprise. Key informant interviews with commercial dairy management and farmers were used to identify current practices for increasing women’s formal market participation—namely, direct payments to women for milk deliveries. Findings from this study indicate that cattle and formal dairy market participation are imbued with gendered meaning that create legitimacy around men’s privilege over dairy proceeds. Interventions in the sector aimed at addressing gender power imbalances must acknowledge this dynamic, and accept the social trade-offs and gendered costs of dairy commercialization. (shrink)

Consumers are bombarded with labels and claims that are intended to address their concerns about how food products are produced, processed, and regulated. Among those are the natural or all-natural claims and the certified organic label. In this study, two focus groups were conducted to explore consumers’ attitudes toward all-natural and organic pork and to gather their reactions to the USDA organic standards for meat, and the policy for natural claims. Results indicated that participants had positive associations with the terms (...) “organic” and “all-natural” with exceptions regarding the trustworthiness of all-natural claims. Participants perceived the “no” labeling theme (no antibiotics, no hormones, no chemicals, etc.) often coupled with the all-natural label on pork products as identifying potential health and animal welfare risks. In response to the USDA standards and policies for labeling pork products as organic or all-natural, participants expressed confusion and had many unanswered questions. (shrink)

In this essay, we suggest practical ways to shift the framing of crisis standards of care toward disability justice. We elaborate on the vision statement provided in the 2010 Institute of Medicine (National Academy of Medicine) “Summary of Guidance for Establishing Crisis Standards of Care for Use in Disaster Situations,” which emphasizes fairness; equitable processes; community and provider engagement, education, and communication; and the rule of law. We argue that interpreting these elements through disability justice entails a commitment to both (...) distributive and recognitive justice. The disability rights movement's demand “Nothing about us, without us” requires substantive inclusion of disabled people in decision‐making related to their interests, including in crisis planning before, during, and after a pandemic like Covid‐19.

We explore how a refugee’s experience of rootlessness may persist after they resettle in a new country. Drawing primarily on “We Refugees,” we focus on assimilation as an uprooting phenomenon that compels a person to forget their roots, thereby perpetuating threats to identity and the loss of community that is a condition for political agency. Arendt presents assimilation in a binary way: a person either conforms to or resists pressures to conform. We seek to move beyond this binary, arguing that (...) the performative quality of the “right to have rights” and the notion of dwelling in-between worlds reveal possibilities for a refugee to assimilate in some ways while reinforcing their rootedness. What emerges from our argument is an Arendtian account of assimilation that offers an alternative picture of navigating assimilation than that captured by the binary between parvenu/conscious pariah.

This article is about the special, subjective concepts we apply to experience, called “phenomenal concepts”. They are of special interest in a number of ways. First, they refer to phenomenal experiences, and the qualitative character of those experiences whose metaphysical status is hotly debated. Conscious experience strike many philosophers as philosophically problematic and difficult to accommodate within a physicalistic metaphysics. Second, PCs are widely thought to be special and unique among concepts. The sense that there is something special about PCs (...) is very closely tied up with features of the epistemic access they afford to qualia. When we deploy phenomenal concepts introspectively to some phenomenally conscious experience as it occurs, we are said to be acquainted with our own conscious experiences. Accounts of PCs either have to explain the acquaintance relation, or acquaintance with our phenomenal experiences has to be denied. PCs have received much attention in recent philosophy of mind mainly because they figure in arguments for dualism and in physicalist responses to these arguments. The main topic of this paper is to explore different accounts of phenomenal concepts and their role in recent debates over the metaphysical status of phenomenal consciousness. (shrink)

The Bayesian maxim for rational learning could be described as conservative change from one probabilistic belief or credence function to another in response to newinformation. Roughly: ‘Hold fixed any credences that are not directly affected by the learning experience.’ This is precisely articulated for the case when we learn that some proposition that we had previously entertained is indeed true (the rule of conditionalisation). But can this conservative-change maxim be extended to revising one’s credences in response to entertaining propositions or (...) concepts of which one was previously unaware? The economists Karni and Vierø (2013, 2015) make a proposal in this spirit. Philosophers have adopted effectively the same rule: revision in response to growing awareness should not affect the relative probabilities of propositions in one’s ‘old’ epistemic state. The rule is compelling, but only under the assumptions that its advocates introduce. It is not a general requirement of rationality, or so we argue. We provide informal counterexamples. And we show that, when awareness grows, the boundary between one’s ‘old’ and ‘new’ epistemic commitments is blurred. Accordingly, there is no general notion of conservative change in this setting.

Eating locally continues to be promoted as an alternative to growing concerns related to industrialized, global, corporate agriculture. Buying from local famers and producers is seen as a way to promote a healthier diet, reduce environmental impacts, and sustain communities. The promotion of the local food movement presents the question: is it possible to feed a community primarily from the foods produced locally? We conducted a systematic analysis comparing the United States Department of Agriculture’s (USDA) recommended dietary requirements for the (...) estimated 2008 population with annual local agricultural production for the years 2004–2008 within the counties of the Willamette Valley growing region. Our results indicate that current agricultural production in this highly fertile region does not meet the dietary needs of the local inhabitants for any of the USDA’s six food groups: grains, vegetables, fruits, dairy, meat and beans, and oils. In the most recent year of our analysis, 2008, Willamette Valley agriculture production met 67% of annual required grains, 10% of vegetable needs, 24% of fruits, 59% of dairy, 58% of meat and beans, and 0% of dietary oil requirements. Over the past 5 years there have been significant fluctuations in crop production, particularly in 2006 when grain yields dropped to 29% of needs met. Additionally, many of these commodities are exported as cash crops, thus not contributing to meeting local food needs. We discuss these results as well as areas of potential for increasing production of edible crops for local consumption in the region. (shrink)

A central problem in the cognitive sciences is identifying the link between consciousness and neural computation. The key features of consciousness—including the emergence of representative information content and the initiation of volitional action—are correlated with neural activity in the cerebral cortex, but not computational processes in spinal reflex circuits or classical computing architecture. To take a new approach toward considering the problem of consciousness, it may be worth re‐examining some outstanding puzzles in neuroscience, focusing on differences between the cerebral cortex (...) and spinal reflex circuits. First, the mammalian cerebral cortex exhibits exascale computational power, a feature that is not strictly correlated with the number of binary computational units; second, individual computational units engage in noisy coding, allowing random electrical events to gate signaling outcomes; third, this noisy coding results in the synchronous firing of statistically random populations of cells across the neural network, at a range of nested frequencies; fourth, the system grows into a more ordered state over time, as it encodes the predictive value gained through observation; and finally, the cerebral cortex is extraordinarily energy efficient, with very little free energy lost to entropy during the work of information processing. Here, I argue that each of these five key features suggest the mammalian brain engages in probabilistic computation. Indeed, by modeling the physical mechanisms of probabilistic computation, we may find a better way to explain the unique emergent features arising from cortical neural networks. (shrink)

Maternal grandmothers play a key role in allomaternal care, directly caring for and provisioning their grandchildren as well as helping their daughters with household chores and productive labor. Previous studies have investigated these contributions across a broad time period, from infancy through toddlerhood. Here, we extend and refine the grandmothering literature to investigate the perinatal period as a critical window for grandmaternal contributions. We propose that mother-daughter co-residence during this period affords targeted grandmaternal effort during a period of heightened vulnerability (...) and appreciable impact. We conducted two focus groups and 37 semi-structured interviews with Himba women. Interviews focused on experiences from their first and, if applicable, their most recent birth and included information on social support, domains of teaching and learning, and infant feeding practices. Our qualitative findings reveal three domains in which grandmothers contribute: learning to mother, breastfeeding support, and postnatal health and well-being. We show that informational, emotional, and instrumental support provided to new mothers and their neonates during the perinatal period can aid in the establishment of the mother-infant bond, buffer maternal energy balance, and improve nutritional outcomes for infants. These findings demonstrate that the role of grandmother can be crucial, even when alloparenting is common and breastfeeding is frequent and highly visible. Situated within the broader anthropological and clinical literature, these findings substantiate the claim that humans have evolved in an adaptive sociocultural perinatal complex in which grandmothers provide significant contributions to the health and well-being of their reproductive-age daughters and grandchildren.

Background: Clinical and experimental findings have suggested that insomnia is associated with altered emotion processing, such as facial emotion recognition and impairments in executive functions. However, the results still appear non-consensual and have recently been presented by a few number of studies. Accordingly, the aim of the present study was to investigate whether patients with Insomnia disorder will present alterations in recognition of facial emotions and that such alterations will be related to Executive Functions and that Insomnia Disorder patients will (...) exhibit a lower Executive Functions performance when compared to normal controls individuals. Method: A total of 11 individuals diagnosed with insomnia disorder and 15 control participants took part in the present cross-sectional study. They completed questionnaires covering socio-demographic data, a sleep and mood evaluation, and a cognitive assessment. Moreover, they underwent a computerized Facial Emotional Recognition test, consisting of facial emotion labeling and facial emotion matching. Results: Individuals with insomnia presented a lower recognition of facial expressions of fear and sadness in comparison to control volunteers. Perceptual Organization Index was found to be statistically significant lower in the insomnia group compared to the control group. There was a statistically significant association between facial recognition emotional and cognitive processes of in executive functions performance, especially in processes related to the inhibitory control, planning capacity, problem solving and cognitive flexibility in insomnia group. Conclusions: Insomnia disorder impairs the facial emotion recognition of the fear and sadness. Insomniacs with impairment in the facial emotion recognition had impaired performance of executive functions. There is a negative impact on processes related to cognitive-emotional capacity than on processes related to social-emotional recognition. Keywords: insomnia, facial emotional recognition, sleep deprivation, cognition, executive functions. (shrink)

The leading ethical problem in medical practice for the coming decade is likely to be how to select patients for priority. Criteria for such decision-making in the case of cancer patients are discussed. Clinicians, ethicists and others need to agree guidelines on giving priority to one patient over another when resources are limited, and such criteria need to be approved by society at large. The public must accept that in a non-explicit rationing system, each individual competes with every other. In (...) the case of even more difficult ethical choices, a multidisciplinary national committee is required to advise on decision-making, and its views need to be debated by the general public.

The ecosystem services argument is a highly publicised instrumental argument for protecting biodiversity. I develop a new objection to this argument based on the lack of a causal connection from global species losses to local ecosystem changes. I survey some alternative formulations of services arguments, including ones incorporating option value or a precautionary principle, and show that they do not fare much better than the standard version. I conclude that environmental thinkers should rely less on ecosystem services as a means (...) to defend biodiversity, and that attention should be focused on additional types of value which might be attributed to global biodiversity.

Ladyman, Presnell, and Short proposed a model of the implementation of logical operations by physical processes in order to clarify the exact statement of Landauer's Principle, and then offered a new proof of the latter based on the construction of a thermodynamic cycle, arguing that if Landauer's Principle were false it would be possible to harness a machine that violated it to produce a violation of the second law of thermodynamics. In a recent paper in this journal, John Norton directly (...) challenges the consistency of that proof. In the present paper we defend the proof given by Ladyman et al. against his critique. In particular, contrary to what Norton claims, we argue that the processes used in the proof cannot be used to construct a cycle that enacts erasure in a thermodynamically reversible way, and that he does not show that the processes used in the proof violate the Second Law of Thermodynamics.

This article defends an account of collective hope that arises through solidarity in the pursuit of justice. I begin by reviewing recent literature on the nature of hope. I then explore the relationship between hope and solidarity to demonstrate the ways in which solidarity can give rise to hope. I suggest that the hope born of solidarity is collective when it is shared by at least some others, when it is caused or strengthened by activity in a collective action setting, (...) and when the reciprocal hopeful expressions of individual group members result in an emotional atmosphere of hope that extends across the group. In the context of social movements, collective hope emerges alongside the collective intentions and actions of the solidarity group; namely, in the pursuit of a form of social justice that inspires the movement. I then suggest that the object of collective hope born of solidarity is the guiding ideal of justice and reflect on what it might mean to hope well for justice. (shrink)

Frequent public uproar over forms of data science that rely on information about people demonstrates the challenges of defining and demonstrating trustworthy digital data research practices. This paper reviews problems of trustworthiness in what we term pervasive data research: scholarship that relies on the rich information generated about people through digital interaction. We highlight the entwined problems of participant unawareness of such research and the relationship of pervasive data research to corporate datafication and surveillance. We suggest a way forward by (...) drawing from the history of a different methodological approach in which researchers have struggled with trustworthy practice: ethnography. To grapple with the colonial legacy of their methods, ethnographers have developed analytic lenses and researcher practices that foreground relations of awareness and power. These lenses are inspiring but also challenging for pervasive data research, given the flattening of contexts inherent in digital data collection. We propose ways that pervasive data researchers can incorporate reflection on awareness and power within their research to support the development of trustworthy data science. (shrink)

This paper traces the history of remoteness in contract law, namely the legal formants (in Rodolfo Sacco’s terms) constraining the availability of contract damages in various legal systems. Our journey takes us through different times, continents and cultures, from the eighteenth century to the twenty–first century, across the law of France, United States, England and Wales, India and Australia, among other jurisdictions. While it might seem that civilian and common law traditions have very different morphological legal forms, once a closer (...) historical, cultural, and anthropological gaze is turned upon the legal formants involved, it can be seen that remoteness discloses a shared concern which may be common to many human societies and cultures. In other words, as a matter of social experience, humans who enter into transactions generally realise that it is impossible to know the future, or to know what all outcomes of the transaction will be. Consequently, it is recognised that it would be unfair and unjust to hold a defendant liable for all outcomes, and as our journey will show, legal systems seek guidance from other legal systems in their efforts to deal with this problem.

While the fundamental laws of physics are time-reversal invariant, most macroscopic processes are irreversible. Given that the fundamental laws are taken to underpin all other processes, how can the fundamental time-symmetry be reconciled with the asymmetry manifest elsewhere? In statistical mechanics, progress can be made with this question. What I dub the ‘Zwanzig–Zeh–Wallace framework’ can be used to construct the irreversible equations of SM from the underlying microdynamics. Yet this framework uses coarse-graining, a procedure that has faced much criticism. I (...) focus on two objections in the literature: claims that coarse-graining makes time-asymmetry ‘illusory’ and ‘anthropocentric’. I argue that these objections arise from an unsatisfactory justification of coarse-graining prevalent in the literature, rather than from coarse-graining itself. This justification relies on the idea of measurement imprecision. By considering the role that abstraction and autonomy play, I provide an alternative justification and offer replies to the illusory and anthropocentric objections. Finally, I consider the broader consequences of this alternative justification: the connection to debates about inter-theoretic reduction and the implication that the time-asymmetry in SM is weakly emergent. 1Introduction 1.1Prospectus2The Zwanzig–Zeh–Wallace Framework3Why Does This Method Work? 3.1The special conditions account3.2When is a density forwards-compatible?4Anthropocentrism and Illusion: Two Objections 4.1The two objections in more detail4.2Against the justification by measurement imprecision5An Alternative Justification 5.1Abstraction and autonomy5.2An illustration: the Game of Life6Reply to Illusory7Reply to Anthropocentric8The Wider Landscape: Concluding Remarks 8.1Inter-theoretic relations8.2The nature of irreversibility.

I develop an account of ecological role functions—the functions of species within ecosystems—which is informed by alternative regime phenomena in ecology. My account is a causal-role theory which includes a counterfactual sensitivity condition. The account tracks and explains a distinction ecologists make between functions and various activities which are not functions. My counterfactual sensitivity condition resolves the liberality problem often attributed to causal-role theories of function, while also illuminating the explanatory centrality of role functions within ecology.

This paper addresses the stalemate on the question whether biodiversity has intrinsic value. I distinguish between a “weak” conception and two “strong” conceptions of intrinsic value in the environmental ethics literature. The strong conceptions of intrinsic value are connected, respectively, to moral standing and to a strongly objectivist account of value. Neither of these forms of value likely applies to biodiversity. However, the weak conception of intrinsic value is neutral about both moral standing and the nature of value and plausibly (...) applies to biodiversity. In addition, weak intrinsic value avoids common objections to the claim that biodiversity is intrinsically valuable. I develop a cumulative argument showing that environmentalists should presume that biodiversity has intrinsic value in the weak sense. (shrink)

In the United States, final amendments to the Federal Policy for the Protection of Human Subjects (“the Common Rule”) were published on January 19, 2017, and they will take effect on January 21, 2019. One of the most widely discussed provisions is that for the first time, federal regulations governing research with humans authorize the use of broad consent for future, unspecified research on individually identifiable biospecimens and associated data. Many questions have been raised about broad consent, including what effect (...) it will have on research and whether it adequately protects the interests of research participants.There are lessons to be learned for the U.S. and other countries by looking to countries that already have experience with broad consent for biobank collection and with the storage and subsequent use of the biospecimens and data. This article describes how broad consent works in five countries—Canada (in Quebec), Israel, Nigeria, Taiwan, and the United Kingdom—and with different types of biobanks: national biobanks, federated biobanks, and regional biobanks. Evaluating the provisions and challenges of the broad consent approaches in these countries can inform policies for this increasingly used approach to biobank regulation. (shrink)
