Although environmental philosophy and the human exploration of space share common beginnings, scholars from either field have not given adequate attention to the possible connections between them. In this essay, we seek to spur the rapprochement and cross-fertilization of philosophy and space policy by highlighting the philosophic dimensions of space exploration, pulling together issues and authors that have had insufficient contact with one another. We do so by offering an account of three topics: planetary exploration, planetary protection and the search (...) for extraterrestrial life, and terraforming. The resulting synthesis seeks to change our thinking about earthbound environmental ethics as it considers the philosophical dimensions of space exploration, and introduces the possible benefits of a humanities-oriented approach to space policy.

In recent decades, environmental rights have been increasingly developed at both the national and international level, along with increased adjudication of these rights in both national (constitutional) courts and international human rights courts. These parallel trends raise a question as to whether it is better to develop and adjudicate environmental rights at the national or international level. This article considers the case made by James May and Erin Daly in favor of developing environmental rights at the national constitutional (...) level and adjudicating these rights in domestic courts. I consider the limitations of this case by showing that international environmental human rights can play a role that systematically benefits environmental protection, with adjudication in international human rights courts a key part of that process. This involves drawing on an argument offered by Allen Buchanan to justify a system of international legal human rights, which appeals to a number of benefits that such a system can provide. The argument is developed and applied to adjudication of environmental human rights in international human rights courts. First, it is shown how these benefits are realized in the area of environmental human rights. Second, it is shown how adjudication can enhance these benefits, both by providing a mechanism for their realization and by facilitating a mutually supportive relationship among them. On the basis of these enhanced benefits and the value that they add, it is concluded that there is strong justification for developing and adjudicating environmental human rights at the international level.

Haeusermann et al. (Citation2023) draw three overall conclusions from their study on closed loop neuromodulation and self-perception in clinical treatment of refractory epilepsy. The first is that closed-loop neuromodulation devices did not substantially change epileptic patient’s personalities or self-perception postoperatively. The second is that some patients and caregivers attributed observed changes in personality and self-perception to the epilepsy itself and not to the DBS treatments. The third is that the devices provided participants with novel ways to make sense of their (...) illness. These findings further demonstrate a misalignment between some neuroethicists’ concerns about putative postoperative changes to personality, and the empirical evidence for such changes. Haeusermann et al. nonetheless concede that “neurotechnology directed at persisting rather than episodic clinical phenomena could have greater implications for personality or self-perception, either because they operate more continuously or are directed at clinical phenomena that are more stably integrated into patients’ self-concepts” (41). We acknowledge that the hypothesis that participants did not report changes because they were only episodically and not continually stimulated offers an interesting line for future investigation. Nonetheless, we would like to propose that potential postoperative personality changes might be correlated with the pathophysiology itself, rather than the stimulation effects of the technology. Generally, we advance the view that unintended effects solely induced by the technology cannot be excluded per se. Regardless, this comment aims to highlight that ethicists’ starting premise should be that patients suffering from diverse pathophysiology, or patients who are treated with stimulation in different brain regions and with differing parameters, would likely not react in the same way to treatment.

Corporate social responsibility research has burgeoned in the past several decades. Despite significant advances, our review of the literature reveals a problematic gap: We know little about how culture, practices, and interactions shape CSR. On further investigation, we discover that limited research utilizes ethnography to understand CSR, which may provide some explanation for this gap. Thus, the purpose of this article is to illustrate the utility of ethnography for advancing business and society research via a multistage framework that demonstrates how (...) three different types of ethnography may be applied to the exploration of CSR. We specifically focus on the alignment between stages in the research process, or methodological fit, as a key criterion of high-quality research. In doing so, we provide researchers embracing different worldviews a tool they may utilize to conduct and evaluate ethnographies in business and society research. (shrink)

Multi-stakeholder initiatives for biodiversity conservation on working landscapes often necessitate strategies to facilitate learning in order to foster successful collaboration. To investigate the learning processes that both undergird and result from collaborative efforts, this case study employs the concept of boundary work as a lens to examine learning between rice growers and conservation professionals in California’s Central Valley, who were engaged in a collaborative research project focused on migratory bird conservation. Through analysis of workshop observations, project documents, and interviews with (...) rice growers and conservation professionals, we identified five distinct factors of the collaborative research process that influenced learning amongst these two groups: having mutually beneficial goals, sharing ownership of the collaborative research process, building trust, integrating knowledge, and institutional alignment. We also examined and identified learning outcomes for both rice growers and conservation professionals, which included new knowledge of the social-ecological system, new practices around farming and collaboration, and shifting identities. Our findings suggest that applying these factors and outcomes for learning when structuring collaborative research, and other multi-stakeholder initiatives, can foster learning amongst diverse stakeholder groups to support new approaches for balancing resource use and adaptive management.

The diverse essays in this volume speak to the relevance of phenomenological and psychological questioning regarding perceptions of the human. This designation, human, can be used beyond the mere identification of a species to underwrite exclusion, denigration, dehumanization and demonization, and to set up a pervasive opposition in Othering all deemed inhuman, nonhuman, or posthuman. As alerted to by Merleau-Ponty, one crucial key for a deeper understanding of these issues is consideration of the nature and scope of perception. Perception defines (...) the world of the perceiver, and perceptual capacities are constituted in engagement with the world – there is co-determination. Moreover, the distinct phenomenology of perception in the spectatorial mode in contrast to the reciprocal mode, deepens the intersubjective and ethical dimensions of such investigations. -/- Questions motivating the essays include: Can objectification and an inhuman gaze serve positive ends? If so, under what constraints and conditions? How is an inhuman gaze achieved and at what cost? How might the emerging insights of the role of perception into our interdependencies and essential sociality from various domains challenge not only theoretical frameworks, but also the practices and institutions of science, medicine, psychiatry and justice? What can we learn from atypical social cognition, psychopathology and animal cognition? Could distortions within the gazer’s emotional responsiveness and habituated aspects of social interaction play a role in the emergence of an inhuman gaze? -/- Perception and the Inhuman Gaze will interest scholars and advanced students working in phenomenology, philosophy of mind, psychology, psychiatry, sociology and social cognition. -/- Table of Contents -/- Introduction -/- Part I.

Injustice can undermine the standing states have to blame criminal offenders, and this raises a difficulty for a range of punishment theories that depend on a state's moral authority. When a state lacks the moral authority that flows from political legitimacy, its right to punish criminal lawbreakers cannot depend on a systematic claim about the legitimacy of the law. Instead, an unjust state is permitted to punish only criminal acts whose wrongness is established directly by morality, and only when criminal (...) guilt is established through legal procedures that meet minimal standards of fairness. These restrictions narrow the proper scope of criminal law and invalidate popular rationales for punishment that construe punishment as blame. (shrink)

Children with developmental language disorder (DLD) served as a test case for determining the role of extant vocabulary knowledge, endogenous attention, and phonological working memory abilities in cross-situational word learning. First-graders (Mage = 7 years; 3 months), 44 with typical development (TD) and 28 with DLD, completed a cross-situational word-learning task comprised six cycles, followed by retention tests and independent assessments of attention, memory, and vocabulary. Children with DLD scored lower than those with TD on all measures of learning and (...) retention, a performance gap that emerged in the first cycle of the cross-situational protocol and that we attribute to weaknesses in initial encoding. Over cycles, children with DLD learned words at a similar rate as their TD peers but they were less flexible in their strategy use, demonstrating a propose-but-verify approach but never a statistical aggregation approach. Also, they drew upon different mechanisms to support their learning. Attention played a greater role for the children with DLD, whereas extant vocabulary size played a greater role for the children with TD. Children navigate the problem space of cross-situational learning via varied routes. This conclusion is offered as motivation for theorists to capture all learners, not just the most typical ones.

If Lyotard is correct to acknowledge the role of commentary in guarding the kernel of misunderstanding at the heart of the ethical phrase when he exclaims, “but isn’t this exactly what commentary does with ethics! It comments upon it as though it were a misunderstanding, and it thereby conserves in itself its own requirement that there be something ununderstood,” he does not account for that which a trans-generic or transmedial “commentary” might permit, what troubling, unanswerable questions it might raise, what (...) ekphrastic or synesthetic call it might echo. This essay considers several artistic reworkings, interpretations, and distortions of the biblical scene of near sacrifice upon which Lyotard comments, arguing that the exposure of the ethical to the explicitly aesthetic would bring to the surface something that might be latent, that which is always already there, albeit spectrally.

Concern has been raised that segregation of girls and boys into separate classes leads to increased gender stereotyping. We tested this in a sample of 365 seventh-grade students attending a junior high school that offers both gender-segregated (GS) and co-educational classes. It was found that for both boys and girls, the more GS classes they took in the fall, the more gender stereotyped they were in their responding in the spring (controlling for initial levels of gender stereotyping). We concluded that (...) GS likely heightens the salience of gender in the classroom thereby reinforcing and increasing gender stereotypes. As such, we argue that GS is a misguided approach to addressing any educational difficulties girls and boys might be having. (shrink)

Many well-meaning “white” people adopt an antiracist agenda because we believe it provides the antidote to pernicious racialized inequity in the United States. Ironically, this schema maintains racism, strengthens whiteness as the measure of humanity, and inoculates us against imagining any alternative to racism’s logic. I argue that we can break the fetters of racism by framing whiteness as a principality and power. Perceived as a demonic force rather than an “identity,” we can perceive the goals of whiteness as well (...) as the spirituality that fuels it—and cast it out. We are then freed to “reinvent the future,” emancipated from racialized politics and its violence. (shrink)

ObjectiveTo determine the effects of learning interventions aimed at optimizing the quality of physical education on psychomotor, cognitive, affective and social learning outcomes in children and adolescents.DesignA systematic review and meta-analysis.Data SourcesAfter searching PsycInfo, ERIC, and SportDiscus electronic databases, we identified 135 eligible studies published between January 1, 1995 to May 1, 2021.Eligibility Criteria for Selecting StudiesWe included randomized controlled trials, quasi-experimental studies, and controlled trials that assessed the effect of a PE-based intervention against one of the four identified learning (...) domains in youth at school.ResultsOne hundred and thirty five studies with over 42,500 participants and 193 calculated effect sizes were included in the study. The mean effect across all the learning and development outcomes was small to medium. When adjusted for publication bias using the Duval and Tweedie Trim and Fill Method, this mean effect size increased to d = 0.40. Effect sizes varied significantly based on learning and development outcomes. Interventions that consistently report above or below the mean d = 0.40 effect are identified based on learning outcome. The greatest effects across interventions were witnessed in psychomotor learning outcomes followed by affective, social, and cognitive learning outcomes. A minority of PE interventions captured by this systematic review and meta-analysis reported having a negative effect on student learning and development.ConclusionThe interventions with the greatest effects on student learning and development were dependant on the learning domains. Some PE interventions with a pedagogical focus such as games-based approaches, TARGET/Mastery Teaching, and Sport Education were found to be strong investments across multiple domains. The evidence is limited however by consistency in intervention dosage, study design, and data collection instruments. The study received no internal or external funding and was not prospectively registered. (shrink)

Neuromuscular synapses are highly dynamic structures that respond to both intercellular and intracellular cues to manipulate synaptic form. A variety of post‐translational modifications of synaptic proteins are used to regulate synaptic plasticity. A recent report by DiAntonio et al.(1) shows that two ubiquitin pathway proteins, Highwire and Fat facets, may be mutually antagonistic regulators of presynaptic growth at the Drosophila neuromuscular junction. This work adds support to the emerging idea that ubiquitin, a polypeptide that targets proteins for proteasomal degradation, regulates (...) synaptic development.

Abstract:Multidisciplinary healthcare workers describe interactions with "difficult" patients that have shaped their lives and their clinical practice. The narrators recall navigating the push-pull of empathy and frustration to forge therapeutic patient relationships in inhospitable, under-resourced environments. Their stories offer glimpses into the traumatized people hiding behind "difficult" patient facades. This commentary explores how the narrators engaged in empathy and obligation to build trusting relationships with patients. To protect themselves and their patients, healthcare workers must engage beyond individual clinical duties to (...) help remodel American healthcare. They should be encouraged to advocate for implementation of trauma informed care and to engage in public discourse about transforming healthcare for the good of healthcare workers, patients, and families.

Project Washoe began in 1966 with Drs. Allen and Beatrix Gardner in Reno, Nevada. There had been other experiments that attempted to get chimpanzees to speak. These experiments were not successful due to anatomical and neurological differences between humans and chimpanzees.

Residual confounding is a common source of bias in observational studies. In this article, we build upon a series of sensitivity analyses methods for residual confounding developed by Brumback et al. and Chiba whose sensitivity parameters are constructed to quantify deviation from conditional exchangeability, given measured confounders. These sensitivity parameters are combined with the observed data to produce a “bias-corrected” estimate of the causal effect of interest. We provide important generalizations of these sensitivity analyses, by allowing for arbitrary exposures and (...) a wide range of different causal effect measures, through the specification of the target causal effect as a parameter in a generalized linear model with the arbitrary link function. We show how our generalized sensitivity analysis can be easily implemented with standard software, and how its sensitivity parameters can be calibrated against measured confounders. We demonstrate our sensitivity analysis with an application to publicly available data from a cohort study of behavior patterns and coronary heart disease. (shrink)

Hume’s moral philosophy is a sentiment-based view. Moral judgment is a matter of the passions; certain traits of character count as virtues or vices because of the approval or disapproval they evoke in us, feelings that express concern we have about the social effects of these traits. A sentiment-based approach is attractive, since morality seems fundamentally to involve caring for other people. Sentiment-based views, however, face a real challenge. It is clear that our affections are often particular; we favor certain (...) persons over others. This poses a problem when it comes to determining the proper content of morality. The ties of sentiment would seem to be in tension with the aspirations of morality toward impartiality and universality. (shrink)

In _Always More Than One_, the philosopher, visual artist, and dancer Erin Manning explores the concept of the "more than human" in the context of movement, perception, and experience. Working from Whitehead's process philosophy and Simondon's theory of individuation, she extends the concepts of movement and relation developed in her earlier work toward the notion of "choreographic thinking." Here, she uses choreographic thinking to explore a mode of perception prior to the settling of experience into established categories. Manning connects (...) this to the concept of "autistic perception," described by autistics as the awareness of a relational field prior to the so-called neurotypical tendency to "chunk" experience into predetermined subjects and objects. Autistics explain that, rather than immediately distinguishing objects—such as chairs and tables and humans—from one another on entering a given environment, they experience the environment as gradually taking form. Manning maintains that this mode of awareness underlies all perception. What we perceive is never first a subject or an object, but an ecology. From this vantage point, she proposes that we consider an ecological politics where movement and relation take precedence over predefined categories, such as the neurotypical and the neurodiverse, or the human and the nonhuman. What would it mean to embrace an ecological politics of collective individuation? (shrink)

Artificial intelligence is again attracting significant attention across all areas of social life. One important sphere of focus is education; many policy makers across the globe view lifelong learning as an essential means to prepare society for an “AI future” and look to AI as a way to “deliver” learning opportunities to meet these needs. AI is a complex social, cultural, and material artifact that is understood and constructed by different stakeholders in varied ways, and these differences have significant social (...) and educational implications that need to be explored. Through analysis of thirty-four in-depth interviews with stakeholders from academia, commerce, and policy, alongside document analysis, we draw on the social construction of technology to illuminate the diverse understandings, perceptions of, and practices around AI. We find three different technological frames emerging from the three social groups and argue that commercial sector practices wield most power. We propose that greater awareness of the differing technical frames, more interactions among a wider set of relevant social groups, and a stronger focus on the kinds of educational outcomes society seeks are needed in order to design AI for learning in ways that facilitate a democratic education for all.

In this wide-ranging and probing book Erin Manning extends her previous inquiries into the politics of movement to the concept of the minor gesture. The minor gesture, although it may pass almost unperceived, transforms the field of relations. More than a chance variation, less than a volition, it requires rethinking common assumptions about human agency and political action. To embrace the minor gesture's power to fashion relations, its capacity to open new modes of experience and manners of expression, is (...) to challenge the ways in which the neurotypical image of the human devalues alternative ways of being moved by and moving through the world—in particular what Manning terms "autistic perception." Drawing on Deleuze and Guattari's schizoanalysis and Whitehead's speculative pragmatism, Manning's far-reaching analyses range from fashion to depression to the writings of autistics, in each case affirming the neurodiversity of the minor and the alternative politics it gestures toward.

Faith in the power and righteousness of retribution has taken over the American criminal justice system. Approaching punishment and responsibility from a philosophical perspective, Limits of Blame takes issue with a criminal justice system that aligns legal criteria of guilt with moral criteria of blameworthiness. Many incarcerated people do not meet the criteria of blameworthiness, even when they are guilty of crimes. The author underscores the problems of exaggerating what criminal guilt indicates, particularly when it is tied to the illusion (...) that we know how long and in what ways criminals should suffer. Our practice of assigning blame has gone beyond a pragmatic need for protection and a moral need to repudiate harmful acts publicly. It represents a desire for retribution that normalizes excessive punishment. Kelly proposes that we abandon our culture of blame and aim at reducing serious crime rather than imposing retribution. Were we to refocus our perspective to fit the relevant moral circumstances and legal criteria, we could endorse a humane, appropriately limited, and more productive approach to criminal justice.--.

Clinical ethicists move in different environments and interface with a variety of stakeholders, and are therefore uniquely positioned to answer the call for equity and anti-racism. We describe why a clinical ethicist should contribute to anti-racism efforts and describe general approaches for addressing racism across institutional contexts, including: (1) addressing racism as a bedside clinical ethics consultant, (2) addressing a wider lens of anti-racism work across multiple ethics consults over time, and (3) addressing racism at the organizational level.

Much has been made of the importance of training ethical, socially conscious engineers, but does US engineering education actually encourage neophytes to take seriously their professional responsibility to public welfare? Counter to such ideals of engagement, I argue that students’ interest in public welfare concerns may actually decline over the course of their engineering education. Using unique longitudinal survey data of students at four colleges, this article examines (a) how students’ public welfare beliefs change during their engineering education, (b) whether (...) engineering programs emphasize engagement, and (c) whether these program emphases are related to students’ public welfare beliefs. I track four specific public welfare considerations: the importance to students of professional/ethical responsibilities, understanding the consequences of technology, understanding how people use machines, and social consciousness. Suggesting a culture of disengagement, I find that the cultural emphases of students’ engineering programs are directly related to their public welfare commitments and students’ public welfare concerns decline significantly over the course of their engineering education. However, these findings also suggest that if engineering programs can dismantle the ideological pillars of disengagement in their local climates, they may foster more engaged engineers. (shrink)

The computations involved in statistical learning have long been debated. Here, we build on work suggesting that a basic memory process, chunking, may account for the processing of statistical regularities into larger units. Drawing on methods from the memory literature, we developed a novel paradigm to test statistical learning by leveraging a robust phenomenon observed in serial recall tasks: that short‐term memory is fundamentally shaped by long‐term distributional learning. In the statistically induced chunking recall (SICR) task, participants are exposed to (...) an artificial language, using a standard statistical learning exposure phase. Afterward, they recall strings of syllables that either follow the statistics of the artificial language or comprise the same syllables presented in a random order. We hypothesized that if individuals had chunked the artificial language into word‐like units, then the statistically structured items would be more accurately recalled relative to the random controls. Our results demonstrate that SICR effectively captures learning in both the auditory and visual modalities, with participants displaying significantly improved recall of the statistically structured items, and even recall specific trigram chunks from the input. SICR also exhibits greater test–retest reliability in the auditory modality and sensitivity to individual differences in both modalities than the standard two‐alternative forced‐choice task. These results thereby provide key empirical support to the chunking account of statistical learning and contribute a valuable new tool to the literature. (shrink)

Why Only Us? Language and Evolution By BerwickRobert C. and ChomskyNoamMassachusetts Institute of Technology, 2015. 224 pp. £17.95 paper.

How linguistic structures evolve so as to become easier to process is addressed by Isbilen and Christiansen for the Now‐or‐Never bottleneck. The authors suggest that this fundamental challenge in language processing is coped with by rapid compression of the transient linguistic input into chunks then to be passed on. As linguistic structures that can be chunked more easily tend to stabilize and proliferate, language evolves to fit learners’ cognitive capabilities.

Conventionalists about promising believe that it is wrong to break a promise because the promisor takes advantage of a useful social convention only to fail to do his part in maintaining it. Anti-conventionalists claim that the wrong of breaking a promise has nothing essentially to do with a social convention. Anti-conventionalists are right that the social convention is not necessary to explain the wrong of breaking most promises. But conventionalists are right that the convention plays an essential role in any (...) satisfactory account of promising. A new conventionalism can explain this by appealing to special features of social conventions. Two of these special features have important implications for any moral requirements they mediate, such as the requirement to keep one's promises and the moral requirements attached to social or occupational roles. First, these requirements will not depend on features of a situation that are inaccessible to typical participants in the convention. Second, these requirements often cannot be tailored to fit the overly unusual circumstances of participants. (shrink)

Sex- and age-specific rates of killing unrelated persons of one’s own sex were computed for Canada (1974–1983), England/Wales (1977–1986), Chicago (1965–1981), and Detroit (1972) from census information and data archives of all homicides known to police. Patterns in relation to sex and age were virtually identical among the four samples, although the rates varied enormously (from 3.7 per million citizens per annum in England/Wales to 216.3 in Detroit). Men’s marital status was related to the probability of committing a same-sex, nonrelative (...) homicide, but age effects remained conspicuous when married and unmarried men were distinguished.These findings and the treatment of age and sex effects by criminologists are discussed in the light of contemporary evolutionary psychological models of sex differences and life-span development. Same-sex homicides in which killer and victim are unrelated can be interpreted as an assay of competitive conflict. In every human society for which relevant information exists, men kill one another vastly more often than do women. Lethal interpersonal competition is especially prevalent among young men, which accords with many other aspects of life-span development in suggesting that sexual selection has maximized male competitive prowess and inclination in young adulthood.
