Intelligible speakers achieve specific vocal tract constrictions in rapid sequence. These constrictions are associated in theory with speech motor goals. Adult-focused models of speech production assume that discrete phonological representations, sequenced into word-length plans for output, define these goals. This assumption introduces a serial order problem for speech. It is also at odds with children's speech. In particular, child phonology and timing control suggest holistic speech plans, and so the hypothesis of whole word production. This hypothesis solves the serial order (...) problem by avoiding it. When the same solution is applied to adult speech the problem becomes how to explain the development of highly intelligible speech. This is the problem addressed here. A modeling approach is used to demonstrate how perceptual-motor units of production emerge over developmental time with the perceptual-motor integration of holistic speech plans that are also phonological representations; the specific argument is that perceptual-motor units are a product of trajectories (nearly) crossing in motor space. The model, which focuses on the integration process, defines the perceptual-motor map as a set of linked pairs of experienced perceptual and motor trajectories. The trajectories are time-based excursions through speaker-defined perceptual and motor spaces. By hypothesis, junctures appear where motor trajectories near or overlap one another in motor space when the shared (or extremely similar) articulatory configurations in these regions are exploited to combine perceptually-linked motor paths along different trajectories. Junctures form in clusters in motor space. These clusters, along with their corresponding (linked) perceptual points, represent perceptual-motor units of production, albeit at the level of speech motor control only. The units serve as pivots in motor space during speaking; they are points of transition from one motor trajectory to another along perceptually-linked paths that are selected to produce best approximations of whole word targets.

We report on rapid perceptual learning of intonation contour categories in adults and 9- to 11-year-old children. Intonation contours are temporally extended patterns, whose perception requires temporal integration and therefore poses significant working memory challenges. Both children and adults form relatively abstract representations of intonation contours: Previously encountered and novel exemplars are categorized together equally often, as long as distance from the prototype is controlled. However, age-related differences in categorization performance also exist. Given the same experience, adults form narrower categories (...) than children. In addition, adults pay more attention to the end of the contour, while children appear to pay equal attention to the beginning and the end. The age range we examine appears to capture the tail-end of the developmental trajectory for learning intonation contour categories: There is a continuous effect of age on category breadth within the child group, but the oldest children are adult-like.

Within the growing developmental literature on children's testimonial learning, the emphasis placed on children's evaluations of testimonial evidence has shielded from view some of the more collaborative dimensions of testimonial learning. Drawing on recent philosophical work on testimony and interpersonal trust, we argue for an alternative way of conceptualizing the social nature of testimonial learning. On this alternative, some testimonial learning is the result of a jointly collaborative epistemic activity, an activity that aims at the epistemic goal of true belief, (...) but that does so by means of an irreducibly social process.

ABSTRACTWhat is the nature of children's trust in testimony? Is it based primarily on evidential correlations between statements and facts, as stated by Hume, or does it derive from an interest in the trustworthiness of particular speakers? In this essay, we explore these questions in an effort to understand the developmental course and cognitive bases of children's extensive reliance on testimony. Recent work shows that, from an early age, children monitor the reliability of particular informants, differentiate between those who make (...) true and false claims and keep that differential accuracy in mind when evaluating new information from these people. We argue that this selective trust is likely to involve the mentalistic appraisal of speakers rather than surface generalizations of their behavior. Finally, we review the significance of children's deference to adult authority on issues of naming and categorization. In addition to challenging a purely inductive account of trust, these and other findings reflect a potentially rich set of tools brought by children to the task of learning from people's testimony.

In this study, we investigated whether differences in the experience of regret may be a potential explanation for damaging behaviours associated with psychopathy and criminal offending. Participants were incarcerated offenders (n = 60) and non-incarcerated controls (n = 20). Psychopathic traits were characterised with the Psychopathic Checklist: Screening Version. Regret was assessed by responses to outcomes on a simulated gambling task. Incarcerated offenders experienced a reduced sense of regret as compared to non-incarcerated controls. We obtained some evidence that specific psychopathic (...) factors and facets could differentially relate to the experience and use of emotions. Our data provide initial evidence of important associations between negative emotions and decision behaviour in the context of criminal offending. (shrink)

In this paper, I take up the challenge that political activism runs the risk of generating abstract freedoms for oppressed subjects and neglecting the effects of oppression on the development of subjectivity. I argue that a political activism in concert with a companion ethics of advocacy and listening is best positioned to improve the political and economic conditions of individuals as well as ensure that they are able to realize their freedom in meaningful action. In this paper I distinguish political (...) emancipation from human emancipation using the political and ethical writings of Simone de Beauvoir. I then argue that a feminist ethics of advocacy and listening can serve the project of human emancipation as emancipatory advocacy. I then return to Beauvoir to illuminate the dynamics of privilege, risk, and ambiguity in emancipatory advocacy through her own activism and advocacy in the case of Djamila Boupacha and Algerian independence.

In this essay I argue that commodity consumption is to the regime of political capitalism at the turn of this century what Michel Foucault claimed for discourses of sexuality in the bio-political state. If I am right, then understanding contemporary subjectivities requires granting greater political credence to practices of commodity consumption than they generally receive and a correlative paradigm shift in our notion of desire - from discourses of sexuality to erotics of appetite. But whatever 'ethical substance' we focus upon (...) when we analyze our contemporary situation I think we must give greater consideration to practices of individual conduct. We must grant due attention to the uses to which our bodies, skills and resources are put, and to our active as well as passive participation in that usage, because our everyday conduct may be the missing link between our professed convictions and our actual political prospects. Key Words: capitalism • commodity consumption • conduct • democracy • ethics • Michel Foucault • freedom • politics • sexuality. (shrink)

We are living in a connected world where our devices, our home appliances, and even our clothes can capture detailed data about our daily lives. One category of connected devices that has garnered particular attention is that of connected toys aimed at children, our most vulnerable population. How can connected toys be regulated within the existing U.S. and EU privacy frameworks? What additional protections will be needed for these devices to continue to thrive in the U.S. and European markets in (...) a way that provides beneficial learning and developmental opportunities to children while also ensuring a baseline standard of privacy and security?

Deliberative democratic theory as developed by Jürgen Habermas struggles in its applicability to particular political communities due to its ideality and abstractness. However, philosophers who level this critique against deliberative theory also find in it resources for addressing the legitimacy of live political discourse as it aims towards rationality. This paper takes up the procedural requirement that legitimacy is provided through, as Seyla Benhabib writes, “the free and unconstrained public deliberation of all about matters of common concern.” Using deliberative theory, (...) I develop a test for judging the success and failure of public discourse, and apply this test to political debates in the United States in 2011–2012 concerning women’s lives: the Violence Against Women Act, the birth control mandate in the Affordable Care Act, the censuring of two female legislators in Michigan, and the congressional testimony of a fetus in Ohio. A central piece of my argument is that the knowledge produced about women’s interests and about women’s epistemic authority undermines their participation in public discourse, thus challenging the legitimacy of the decisions resulting from these instances of deliberation.

This research illuminates struggles over cultural definitions of femininity by examining how cultural gatekeepers respond to girls' vocal critique of inauthentic media images. Interviews with 10 editors at two national girls' magazine organizations provide a rare glimpse into their contradictory responses to requests for depicting “real girls.” Editors legitimate and share in the critique, claiming they should change images but cannot. In these accounts, they reveal struggles over altering narrow images of femininity at the organizational and institutional levels. Editors also (...) delegitimate girls' critique as misguided by calling on the media organizations' norms and schemas about how the reader is supposed to understand the images. Paradoxically, here, editors claim that they can change images but should not. Ultimately, the power of girls' resistance is tempered, as both sets of responses lead to the girls' critique being inefficacious in redefining femininity. The study contributes to an understanding of how femininity-defining cultural institutions operate to create and sustain gender stratification. (shrink)

Using psychosocial acceleration theory, this multimethod, multi-reporter study examines how early adversity adaptively shapes the development of a self-regulation construct: effortful control. Investigation of links between early life harshness and unpredictability and the development of effortful control could facilitate a nuanced understanding of early environmental effects on cognitive and social development. Using the Building Strong Families national longitudinal data set, aspects of early environmental harshness and early environmental unpredictability were tested as unique predictors of effortful control at age 3 using (...) multiple regression. Early harshness variables were financial harshness, mothers’ and fathers’ observed parenting, mothers’ and fathers’ reported use of harsh discipline, and harsh neighborhood conditions. Early unpredictability was measured by number of paternal transitions. Cues of harshness, specifically observed unresponsive parenting, observed harsh parenting, and neighborhood harshness, did significantly negatively predict effortful control. Paternal transitions also significantly predicted effortful control, but in the opposite (i.e., positive) direction. The results corroborate previous research linking quality of parenting to the development of children’s effortful control and place it within an evolutionary-developmental theoretical framework. Further, the results suggest that neighborhood harshness may also direct developmental trajectories of effortful control in young children, though the mechanisms through which this occurs are still unclear. This is the first study to explicitly investigate effortful control development in early childhood within the harshness and unpredictability framework. (shrink)

The authors examine the claim that the most recent cohort of U.S. women is reluctant to identify as feminist although it has egalitarian gender attitudes. Using two national surveys, they show that the most recent generation is no less likely than prior cohorts to identify as feminist. However, Baby Bust women are less apt to identify as feminist than are older women, once background characteristics and attitudes related to feminist identification are controlled. Analyses suggest this reluctance is not due to (...) an aversion to feminism but reflects the “off” timing of the feminist movement in the lives of Baby Bust women. The authors also find important differences among cohorts in the correlates of feminist identity. Most notably, the relationships of political ideology and gender attitudes to feminist identity are stronger among Baby Boom women, who came of age during the feminist movement’s second wave, than among older and younger women.

Nanomaterials have the promise of revolutionizing current treatment and diagnosis of diseases, which has led to 33 nanotherapeutics drugs currently on the market and many more in various stages of clinical trials. With an increasing number of products available and in development, along with the unique, emergent properties of the nanoparticle therapeutics themselves, regulatory agencies are now faced with decisions regarding the regulation of such novel technologies. Regulatory guidance, particularly in pre-clinical stages, has the potential to facilitate quick and safe (...) development of these novel materials, but new regulation beyond what is currently in place must be justified in a clear and distinctive toxic response. Herein, we examine literature that compares and correlates in vivo and in vitro nanotoxicity studies to gain a deeper understanding of the modes of nanoparticle toxicity. Additionally, this comparison aims to identify clear and unique toxicity responses caused by nanoparticles, which informs our perspective on pre-clinical nanotherapeutic oversight. (shrink)

Much of the focus of the published 2011 symposium that inspired this work focused on the question, “When have you reduced risk enough to move from bench/animal studies to ‘first in-human’ studies?” Building applied research ethics related to nanotherapeutics requires bench and clinical scientists to have a clear vision about how to test nanotherapeutic safety, and it is clear that there is still much to be considered at the steps before “in-human” assessment. Herein, the perspective of the bench scientist is (...) brought to bear on using in vivo and in vitro models to assess the safety of nanotherapeutics. Much of this work falls under the purview of the field of nanotoxicology that aims to understand the toxicological impact of engineered nanoscale materials. Engineered nanomaterials include a wide variety of materials that are manipulated and controlled on the nanoscale level where, typically, the nanoparticle or nanomaterial has some dimension that is less than 100 nm.

In many species the mutation rate is higher in males than in females, a phenomenon denoted as male mutation bias. This is often observed in animals where males produce many more sperm than females produce eggs, and is thought to result from differences in the number of replication‐associated mutations accumulated in each sex. Thus, studies of male mutation bias have the capacity to reveal information about the replication‐dependent or replication‐independent nature of different mutations. The availability of whole genome sequences for (...) many species, as well as for multiple individuals within a species, has opened the door to studying factors, both sequence‐specific and those acting on the genome globally, that affect differences in mutation rates between males and females. Here, we assess the advantages that genomic sequences provide for studies of male mutation bias and general mutation mechanisms, discuss major challenges left unresolved, and speculate about the direction of future studies.

The Ontology for Biomedical Investigations (OBI) is an ontology that provides terms with precisely defined meanings to describe all aspects of how investigations in the biological and medical domains are conducted. OBI re-uses ontologies that provide a representation of biomedical knowledge from the Open Biological and Biomedical Ontologies (OBO) project and adds the ability to describe how this knowledge was derived. We here describe the state of OBI and several applications that are using it, such as adding semantic expressivity to (...) existing databases, building data entry forms, and enabling interoperability between knowledge resources. OBI covers all phases of the investigation process, such as planning, execution and reporting. It represents information and material entities that participate in these processes, as well as roles and functions. Prior to OBI, it was not possible to use a single internally consistent resource that could be applied to multiple types of experiments for these applications. OBI has made this possible by creating terms for entities involved in biological and medical investigations and by importing parts of other biomedical ontologies such as GO, Chemical Entities of Biological Interest (ChEBI) and Phenotype Attribute and Trait Ontology (PATO) without altering their meaning. OBI is being used in a wide range of projects covering genomics, multi-omics, immunology, and catalogs of services. OBI has also spawned other ontologies (Information Artifact Ontology) and methods for importing parts of ontologies (Minimum information to reference an external ontology term (MIREOT)). The OBI project is an open cross-disciplinary collaborative effort, encompassing multiple research communities from around the globe. To date, OBI has created 2366 classes and 40 relations along with textual and formal definitions. The OBI Consortium maintains a web resource providing details on the people, policies, and issues being addressed in association with OBI. (shrink)

Biological ontologies are used to organize, curate, and interpret the vast quantities of data arising from biological experiments. While this works well when using a single ontology, integrating multiple ontologies can be problematic, as they are developed independently, which can lead to incompatibilities. The Open Biological and Biomedical Ontologies Foundry was created to address this by facilitating the development, harmonization, application, and sharing of ontologies, guided by a set of overarching principles. One challenge in reaching these goals was that the (...) OBO principles were not originally encoded in a precise fashion, and interpretation was subjective. Here we show how we have addressed this by formally encoding the OBO principles as operational rules and implementing a suite of automated validation checks and a dashboard for objectively evaluating each ontology’s compliance with each principle. This entailed a substantial effort to curate metadata across all ontologies and to coordinate with individual stakeholders. We have applied these checks across the full OBO suite of ontologies, revealing areas where individual ontologies require changes to conform to our principles. Our work demonstrates how a sizable federated community can be organized and evaluated on objective criteria that help improve overall quality and interoperability, which is vital for the sustenance of the OBO project and towards the overall goals of making data FAIR.

In light of grand societal challenges, most recently the global Covid-19 pandemic, there is a call for research on responsible leadership. While significant advances have been made in recent years towards a better understanding of the concept, a gap exists in the understanding of responsible leadership in emerging countries, specifically how leaders resolve prevalent moral dilemmas. Following Werhane, we use moral imagination as an analytical approach to analyze a dilemmatic stakeholder conflict through the lense of different responsible leadership mindsets and (...) in light of different ethical principles and moral background theories. Based on this analysis, we arrive at a tentative moral judgement, concluding that the instrumental approach is morally inferior and recommending the integrative approach as the morally superior choice. In the subsequent discussion—focussed on what “could” be done, we apply the integrative script and use moral imagination as a pathway for generating morally justifiable solutions. Through this analysis, we provide novel insights on how to apply an integrative responsible leadership approach to a stakeholder conflict situation, using the single case study to expand the responsible leadership discussion to emerging markets.

How do children acquire beliefs from testimony? In this chapter, we discuss children’s trust in testimony, their sensitivity to and use of defeaters, and their appeals to positive reasons for trusting what other people tell them. Empirical evidence shows that, from an early age, children have a tendency to trust testimony. However, this tendency to trust is accompanied by sensitivity to cues that suggest unreliability, including inaccuracy of the message and characteristics of the speaker. Not only are children sensitive to (...) evidence of unreliability, but they are also sensitive to the positive reasons a speaker may have for the reliability of their testimony. This evidence is discussed in relation to reductivist and non-reductivist viewpoints. (shrink)

Background: In 2006, the Centers for Disease Control and Prevention (CDC) recommended three changes to HIV testing methods in US healthcare settings: (1) an opt-out approach, (2) removal of separate signed consent, and (3) optional HIV prevention counseling. These recommendations led to a public debate about their moral acceptability. Methods: We interviewed 25 members from the fields of US HIV advocacy, care, policy, and research about the ethical merits and demerits of the three changes to HIV testing methods. We performed (...) a qualitative analysis of the participant responses in the interviews and summarized the major themes. Results: In general, arguments in favor of the methods were based upon their ultimate contribution to increasing HIV testing and permitting the consequent benefits of identifying those who are HIV infected and linking them to further care. Conclusions: The prevailing theme of ethical concern focused on suspicions that the methods might not be properly implemented, and that further safeguards might be needed. (shrink)

This study examines steroid production in fathers watching their children compete, extending previous research of vicarious success or failure on men’s hormone levels. Salivary testosterone and cortisol levels were measured in 18 fathers watching their children play in a soccer tournament. Participants completed a survey about the game and provided demographic information. Fathers with higher pregame testosterone levels were more likely to report that referees were biased against their children’s teams, and pre- to postgame testosterone elevation was predicted by watching (...) sons compete rather than daughters as well as perceptions of unfair officiating. Pregame cortisol was not associated with pregame testosterone or with perceived officiating bias, but cortisol did fluctuate synergistically with testosterone during spectator competition. Although fathers showed no consistent testosterone change in response to winning or losing, pregame testosterone may mediate steroid hormone reactivity to other aspects of their children’s competition.

In this paper, we address the four remaining elements that concern HIV screening policy changes: (...)

The self-disorder model provides a phenomenological framework for understanding how the core symptoms of Schizophrenia Spectrum Disorders (SSDs) are rooted in an instability of minimal selfhood. This instability involves a range of “anomalous experiences”: transformations in an individual’s perceptual field and sense of being an agent of action. The explanatory value of this theoretical model can be summarized in two claims about the role of anomalous experiences in self-disorders: (1) anomalous experiences express a common trait-like disturbance that is characteristic of (...) SSDs, and (2) anomalous experiences contribute to explanations regarding how self-disorders progress into SSDs. While hypotheses consistent with the first claim have been substantiated in several studies, hypotheses consistent with the second claim remain underexamined. We argue that attending to this gap in the literature requires considering which methodological strategies are best suited for investigating if and how anomalous experiences contribute to the development of self-disorders into SSDs and psychotic states. Network modeling is discussed as one such strategy suitable for examining the role of anomalies of lived-world in the maintenance of paranoid delusions in SSDs. (shrink)

In this study, the researchers investigated the relationships between character strengths and ethical engagement in online faculty. One of the ethical duties for higher education faculty is to engage in effective teaching practices. As online higher education becomes increasingly popular, online faculty also bear this duty. Numerous studies have shown that character strengths cultivate ethical behavior. Hence, we sought to determine the relationship between character strengths and ethical engagement in online faculty. Specifically, we focused on intellectual character strengths, interpersonal character (...) strengths, and emotional character strengths because of their relevance to online faculty’s teaching practices. Through correlational analyses, we learned that interpersonal and emotional character strengths were positively and moderately related to ethical engagement, whereas intellectual character strengths were weakly related to ethical engagement. The findings of this study provide insight into online faculty’s character strengths and ethical engagement. However, further research is needed to understand the role of character strengths and ethical engagement in promoting effective teaching practices in online higher education classrooms. (shrink)
