Three recent reports (1–3) identify two genes, thick veins (tkv) and saxophone (sax), which encode serine/threonine transmembrane proteins that act as receptors for mediating different aspects of the Drosophila TGF‐β‐related signal, dpp. tkv is required for patterning the entire embryonic dorsal region, while sax is required for patterning only amnioserosa, the dorsalmost cell fates. dpp signaling in other developmental processes again requires both tkv and sax, but to differing degrees. tkv and sax, encode type I receptors, which appear to directly (...) bind ligand, unlike what has been observed for other type I receptors.

In this book Kristi A. Olson addresses the question of fair labor income distribution by proposing the solidarity solution, a new test she defines and defends. She takes as her starting point the envy test, discussed by the philosophers Ronald Dworkin and Philippe Van Parijs and by the economists Jan Tinbergen, Hal Varian, Marc Fleurbaey, Duncan Foley, and Serge-Christophe Kolm. According to the envy test, a distribution is fair when no one prefers someone else's circumstances to their own. After (...) rejecting the envy test, Olson distinguishes two types of envy: personal and impersonal. Impersonal envy makes a demand on others; personal envy, in contrast, does not. Using this distinction, Olson argues that fair labor-income bundles must be impersonal envy-free, but need not be personal envy-free. The book concludes by relating the solidarity solution to concrete problems such as the gender wage gap and taxation. (shrink)

This article describes a qualitative content analysis of 37 elementary examples of social studies Inquiry Design Models (C3 Teachers, 2023a), conducted with the purpose of identifying the core student skills necessary to successfully engage in these inquiries. Prior research identifies core inquiry teaching skills for teachers across content areas and grade bands, but there has been little research on the demands placed on elementary students in social studies inquiry. In this study, we identify 33 broad skills, each of which are (...) observable and teachable. Four of these skills occurred in high frequency: generation of new ideas ( n = 152), writing process ( n = 110), linking evidence with claims ( n = 65), and discussion ( n = 63). These most frequently occurring skills all required higher-level and/or critical thinking. Implications for preservice and in-service teacher education are discussed. (shrink)

Unlike the traditional earnings tax which is based on the individual’s actual income, the endowment tax is based on the individual’s maximum potential income. The endowment tax raises a frightful prospect: an individual taxed according to her potential income as, say, a corporate lawyer might be forced to give up her preferred occupation as a philosophy professor and to work as a corporate lawyer in order to pay her taxes. Although this seems to be an impermissible intrusion on freedom, the (...) challenge is to specify why the endowment tax is impermissible in a way that does not rule out all forms of taxation. After showing why the solutions put forward by John Rawls and by Liam Murphy and Thomas Nagel fail, I provide my own solution. I claim that the endowment tax is impermissible not because it forecloses more options but because of which options it forecloses. Thus, in order to explain the impermissibility of the endowment tax, we first need to distinguish the options to which individuals have a legitimate moral claim. I suggest one way of drawing this distinction by appealing to two principles widely embraced in the philosophical literature. If my argument is right, then the income tax as it is currently implemented is also morally impermissible. (shrink)

In his account of fairness in international trade, Aaron James distinguishes autarkic gains from the gains of trade. Since the autarkic gains are external to the practice of trade, James's account allows each country to keep these gains. The gains of trade, in contrast, must be distributed equally. This distinction suffers from three problems. First, James's autarkic adjustment not only allows inequalities to persist, but exacerbates and creates new ones. Second, there is no non-morally arbitrary way to determine the autarkic (...) gains. Finally, by favouring his account over more egalitarian options, James does not merely set autarkic gains aside as external to the practice of trade but rather implicitly endorses a moral entitlement to autarkic gains without argumentation.

Suppose you and I are dividing a cake between us. If you divide and I choose, then—under standard assumptions—the distribution will be not only fair, but also envy-free. That is, neither of us prefers the other slice. The question that interests me in this essay, however, is the relationship between envy and fairness. Specifically, is it merely a coincidence that the envy-free distribution is fair, or does envy-freeness capture something important about fairness? I argue that envy-freeness does indeed capture something (...) about fairness. Yet, envy-minimizing—the compromise approach—does not. I first show that fairness does not plausibly require envy-minimizing; I then offer an explanation. Namely, envy-minimizing depends on the assumption that all envy is normatively equivalent. This assumption, however, is false. To illustrate, I introduce two types of envy—personal envy and impersonal envy—and show that impersonal envy is normatively significant in a way that personal envy is not. Specifically, impersonal envy is compatible with the rules of mutual justifiability; personal envy is not. I then use this distinction to explain the relationship between fairness and envy-freeness. In the process, the essay provides guidance on the fair division of heterogeneous and non-divisible goods. (shrink)

According to recent empirical studies, much, if not all, of the gender wage gap is attributable to individual choice. Women tend to choose lower-paying jobs and to prioritize family over career while men tend to do the opposite. This has led some policymakers to conclude that the gender wage gap does not require rectification. Although feminists have typically responded by refuting the empirical claim, I argue in this essay that they should also refute the normative claim. In particular, individual choice (...) does not exonerate the gender wage gap if the options from which women and men choose are biased in favor of men. Yet, despite extensive research on individual choice, virtually no attention has been paid to the effect of the state’s choice of regulatory regime on the gender wage gap. Inthis essay, I suggest some of the mechanisms—e.g., licensing laws and scope of practice restrictions—that could potentially bias wages in favor of men. (shrink)

According to the trilemma claim, we cannot have all three of equality, Pareto, and freedom of occupational choice. In response to the trilemma, John Rawls famously sacrificed equality by introducing incentives. In contrast, GA Cohen and others argued that we can, in fact, have all three provided that individuals are properly motivated by an egalitarian ethos. The incentives debate, then, concerns the plausibility of the ethos solution versus the plausibility of the incentives solution. Considerable ink has been spilled on both (...) sides of the debate. Yet, in this essay, I argue that we cannot have this debate until we clarify the terms. Once we clarify the terms, however, we might discover that there is no debate to be had. This is because, depending on how equality, Pareto, and freedom of occupational choice are interpreted, there might not be a trilemma in the first place. Specifically, I use a small but crucial distinction in how equality, the egalitarian ethos, and Pareto are assessed – what I call the internal/external distinction – to disentangle the various paths each solution – the ethos or incentives – could take. I conclude that both solutions have gained illicit plausibility by virtue of not keeping the distinction straight. (shrink)

The purpose of this study is to describe ways in which elementary students access information from various components of informational social studies texts in schools. Although the time devoted to elementary social studies has decreased considerably in recent years, a renewed focus on content-area literacy skills, driven by state standard initiatives, presents us with the opportunity to regain lost social studies instructional time by integrating social studies content during literacy instructional time. However, it is not entirely clear what this instructional (...) time should entail. This paper describes how third-, fourth-, and fifth-grade children navigate various aspects of the written and graphical elements of informational social studies reading materials. Results indicate that when students are unable to correctly answer questions about the content of the reading materials, they primarily attempt to do so in one of four ways: (1) responding without the use of a discernable strategy; (2) extracting random information from the passage; (3) relying on prior knowledge; or, (4) extracting information from the correct aspect of text that is not responsive to the question. Based on researcher-developed reading assessments as data sources, we explain the challenges children encounter and make recommendations for elementary social studies instruction. (shrink)

Moderate physiological or emotional arousal induced after learning modulates memory consolidation, helping to distinguish important memories from trivial ones. Yet, the contribution of subjective awareness or interpretation of arousal to this effect is uncertain. Alexithymia, which is an inability to describe or identify one’s emotional and arousal states even though physiological responses to arousal are intact, provides a tool to evaluate the role of arousal interpretation. Participants scoring high and low on alexithymia learned a list of 30 words, followed by (...) immediate recall. Participants then saw either an arousing or neutral video . Memory was tested 24-h later. Physiological response to arousal was comparable between groups, but subjective response to arousal was impaired in high alexithymia. Yet, delayed word recognition was enhanced by arousal regardless of alexithymia status. Thus, subjective response to arousal, i.e., cognitive appraisal, was not necessary for memory modulation to occur. (shrink)

The non-citizen is the new ?other?. From popular discourse to political pronouncements and academic research, the non-citizen has become one of the subjects du jour. Among the ranks of the non-citizen, one finds a lesser-known category of people which has yet to be considered seriously by liberal political theory ? the stateless. Thus far, liberal political theory has either ignored this category of persons or subsumed them under the subjects of immigration or refugeehood. The present article challenges this theoretical exclusion (...) in two ways. First, it analyses the treatment of statelessness within the works of three prominent theorists on just membership ? Michael Walzer, Seyla Benhabib and William Barbieri, Jr ? and contends that these authors ignore the stateless as a unique category of non-citizen. Secondly, it explains why statelessness demands a distinct theoretical framework than is currently provided for within liberal political theory. The article contends that just membership questions necessitate not simply looking at who is let in and what naturalization procedures should be extended to them, but also entails examining who has always been on the inside and to whom we need to justify their continued exclusion.

Verbal protocol methodology is used to examine how fourth-grade students construct meaning as they read and respond to two informational social studies texts. Results indicate most students are active readers, often engaging in higher-level comprehension strategies and critical thinking as they read independently. However, critical thinking and comprehension processes are not often captured in their responses to end-of-reading questions (ERQ), which as a result have limited scope and utility for guiding social studies instruction. Results also indicate that when students change (...) their patterns of strategy use for reading and responding to text in response to a change in text, they are more successful on the ERQ than when their strategy use remains stagnant.

Alexithymia is associated with emotion processing deficits, particularly for negative emotional information. However, also common are a high prevalence of somatic symptoms and the perception of somatic sensations as distressing. Although little research has yet been conducted on memory in alexithymia, we hypothesized a paradoxical effect of alexithymia on memory. Specifically, recall of negative emotional words was expected to be reduced in alexithymia, while memory for illness words was expected to be enhanced in alexithymia.Eighty-five high or low alexithymia participants viewed (...) and rated arousing illness-related , emotionally positive , negative , and neutral words . Recall was assessed 45 min later.High alexithymia participants recalled significantly fewer negative emotion words but also more illness-related words than low alexithymia participants. The results suggest that personal relevance can shape cognitive processing of stimuli, even to enhance retention of a subclass of stimuli whose retention is generally impaired in alexithymia.

It is common practice for social studies in the elementary school day to be integrated into other subject areas, especially language arts. Also common in an elementary school day are unstructured spaces such as snack time or recess. In this paper, we present findings from a larger study on social studies integration within various subject areas to explore how two teachers (first and fifth grade) integrated social studies into unstructured spaces. These teachers integrated social studies concepts and experiences into morning (...) work, community building, snack time, and after-lunch reading to varying degrees. This study provides an inroad for conversation among researchers, teacher educators, and practicing teachers about the ideals and reality of elementary social studies with the hope of deepening students’ experiences.

Critical cellular functions, including stem cell maintenance, fate determination, and cellular behavior, are governed by canonical Wnt signaling, an evolutionarily conserved pathway whose intracellular signal is transduced by β‐catentin. Emerging evidence suggests that canonical Wnt signaling influences cellular aging, indicating that increases in Wnt signaling delay age‐related deficits.1 However, recent Science papers suggest that Wnt signaling accelerates the onset of aging.2,3 In an attempt to resolve this paradox and clarify how Wnt signaling affects aging, we provide a selective review of (...) research relevant to Wnt signaling and aging.

It has been theorized that the contagion of behaviors may be related to social cognitive abilities, but empirical findings are inconsistent. We recorded young adults’ behavioral expression of contagious yawning and contagious smiling to video stimuli and employed a multi-method assessment of sociocognitive abilities including self-reported internal experience of emotional contagion, self-reported trait empathy, accuracy on a theory of mind task, and observed helping behavior. Results revealed that contagious yawners reported increases in tiredness from pre- to post-video stimuli exposure, providing (...) support for the internal experience of emotional contagion, and were more likely to provide help to the experimenter relative to non-contagious yawners. Contagious smilers showed stably high levels of self-reported happiness from pre- to post-video exposure, were more likely to provide help to the experimenter, and had increased accuracy on a theory of mind task relative to non-contagious smilers. There were no differences in self-reported trait empathy for contagious versus non-contagious yawners or smilers. Contagious yawning may be related to some basic (i.e., emotional contagion) and advanced (i.e., helping behavior) sociocognitive processes, whereas contagious smiling is related to some advanced sociocognitive processes (i.e., theory of mind and helping behavior).

One argument for the moving spotlight theory is that it better explains certain aspects of our temporal phenomenology than does any static theory of time. Call this the argument from passage phenomenology. In this paper it is argued that insofar as moving spotlight theorists take this to be a sound argument they ought embrace a new version of the moving spotlight theory according to which the moving spotlight is a cresting wave of causal efficacy. On this view it is more (...) than just presentness that is temporary: a range of other fundamental properties are also temporary because presentness synchronically changes the fundamental properties that are instantiated in the present moment, from those instantiated when that moment is future, or past. On this view having experiences as of presentness co-varies with the presence of presentness, allowing the moving spotlight theorist to provide a compelling explanation for why we have the temporal phenomenology we do, and to explain how we can know that we are present by reflecting on the nature of said phenomenology.

Socrates famously compares himself to a midwife in Plato'sTheaetetus.

In this ritual, calledUpanayana, the teacher is presented as becoming pregnant with the student. TheArthavavedastates:The teacher leads the student towards himself, makes him an embryo within; he bears him in his belly three nights.

Many think that sentences about what metaphysically explains what are true iff there exist grounding relations. This suggests that sceptics about grounding should be error theorists about metaphysical explanation. We think there is a better option: a theory of metaphysical explanation which offers truth conditions for claims about what metaphysically explains what that are not couched in terms of grounding relations, but are instead couched in terms of, inter alia, psychological facts. We do not argue that our account is superior (...) to grounding-based accounts. Rather, we offer it to those already ill-disposed towards grounding. (shrink)

Kant's Critique of Judgment seems not to be an obviously unified work. Unlike other attempts to comprehend it as a unity, which treat it as serving either practical or theoretical interests, Kristi Sweet's book posits it as examining a genuinely independent sphere of human life. In her in-depth account of Kant's Critical philosophical system, Sweet argues that the Critique addresses the question: for what may I hope? The answer is given in Kant's account of 'territory,' a region of experience (...) that both underlies and mediates between freedom and nature. Territory forms the context in which purposiveness without a purpose, the Ideal of Beauty, the sensus communis, genius and aesthetic ideas, and Kant's conception of life and proof of God are best interpreted. Encounters in this sphere are shown to refer us to a larger, more cosmic sense of a whole to which both freedom and nature belong. (shrink)

Kant's 'practical philosophy' comprehends a diverse group of his writings on ethics, politics, law, religion, and the philosophy of history and culture. Kristi E. Sweet demonstrates the unity and interdependence of these writings by showing how they take as their animating principle the human desire for what Kant calls the unconditioned - understood in the context of his practical thought as human freedom. She traces the relationship between this desire for freedom and the multiple forms of finitude that confront (...) human beings in different aspects of practical life, and stresses the interdependence of the pursuit of individual moral goodness and the formation of community through the state, religion, culture and history. This study of Kant's approach to practical life discovers that doing our duty, itself the realization of our individual freedom, requires that we set for ourselves and pursue a whole constellation of social, political and other communal ends.

This paper presents the strongest version of a non-perdurantist four-dimensionalism: a theory according to which persisting objects are four-dimensionally extended in space-time, but not in virtue of having maximal temporal parts. The aims of considering such a view are twofold. First, to evaluate whether such an account could provide a plausible middle ground between the two main competitor accounts of persistence: three-dimensionalism and perdurantist four-dimensionalism. Second, to see what light such a theory sheds on the debate between these two competitor (...) theories. I conclude that despite prima facie reasons to suppose that non-perdurantist four-dimensionalism might be a credible alternative to either other account of persistence, ultimately the view is unsuccessful. The reasons for its failure illuminate the sometimes stagnant debate between three-dimensionalists and perdurantists, providing new reasons to prefer a perdurantist metaphysics. (shrink)

According to the No Alternate Possibilities argument, if time passes then the rate at which it passes could be different but time cannot pass at different rates, and hence time cannot pass. Typically, defenders of the NAP argument have focussed on defending premise, and have taken the truth of for granted: they accept the orthodox view of rate necessitarianism. In this paper we argue that the defender of the NAP argument needs to turn her attention to. We describe a series (...) of worlds that appear to contain differential passage: worlds where time passes at different rates in different subregions. If the NAP argument is to succeed, rate necessitarians must show that each of these worlds is either metaphysically impossible, or does not contain differential passage. (shrink)

Recent work in personal identity has emphasized the importance of various conventions, or ‘person-directed practices’ in the determination of personal identity. An interesting question arises as to whether we should think that there are any entities that have, in some interesting sense, conventional identity conditions. We think that the best way to understand such work about practices and conventions is the strongest and most radical. If these considerations are correct, persons are, on our view, conventional constructs: they are in part (...) constituted by certain conventions. A person exists only if the relevant conventions exist. A person will be a conscious being of a certain kind combined with a set of conventions. Some of those conventions are encoded in the being itself, so requiring the conventions to exist is requiring the conscious being to be organized in a particular way. In most cases the conventions in question are settled. There is no dispute about what the conventions are, and thus no dispute about which events a person can survive. These are cases where we take the conventions so much for granted, that it is easy to forget that they are there, and that they are necessary constituents of persons. Sometimes though, conventions are not settled. Sometimes there is a dispute about what the conventions should be, and thus a dispute about what events a person can survive. These are the traditional puzzle cases of personal identity. That it appears that conventions play a part in determining persons’ persistence conditions only in these puzzle cases is explained by the fact that only in these cases are the conventions unsettled. Settled or not though, conventions are necessary constituents of persons. (shrink)

On December 3, 2014, in a piece entitled “White America’s Scary Delusion: Why Its Sense of Black Humanity Is So Skewed,” Brittney Cooper criticizes attempts to deem Black rage at state-sanctioned violence against Black people “unreasonable.” In this paper, I outline a problem with epistemology that Cooper highlights in order to explore whether beliefs can wrong. My overall claim is there are difficult-to-defeat arguments concerning the “legitimacy” of police slayings against Black people that are indicative of problems with epistemology because (...) of the epistemic power they accumulate toward resilient oblivion, which can have the effect of normalizing oppressive conditions. That is to say, if one takes the value of lessening oppression as a key feature of normative, epistemological conduct, then it can generate demands on epistemological orientations that, in turn, generate wrongs for beliefs and, more specifically, beliefs as wrongs.
