The powerful combination of genetic, developmental and molecular approaches possible with the fruit fly, Drosophila melanogaster, has led to a profound understanding of the genetic control of early developmental events. However, Drosophila is a highly specialized long germ insect, and the mechanisms controlling its early development may not be typical of insects or Arthropods in general. The beetle, Tribolium castaneum, offers a similar opportunity to integrate high resolution genetic analysis with the developmental/molecular approaches currently used in other organisms. Early results (...) document significant differences between insect orders in the functions of genes responsible for establishing developmental commitments. (shrink)

The Monographs produced by the International Agency for Research on Cancer (IARC) apply rigorous procedures for the scientific review and evaluation of carcinogenic hazards by independent experts. The Preamble to the IARC Monographs, which outlines these procedures, was updated in 2019, following recommendations of a 2018 expert Advisory Group. This article presents the key features of the updated Preamble, a major milestone that will enable IARC to take advantage of recent scientific and procedural advances made during the 12 years since (...) the last Preamble amendments. The updated Preamble formalizes important developments already being pioneered in the Monographs Programme. These developments were taken forward in a clarified and strengthened process for identifying, reviewing, evaluating and integrating evidence to identify causes of human cancer. The advancements adopted include strengthening of systematic review methodologies; greater emphasis on mechanistic evidence, based on key characteristics of carcinogens; greater consideration of quality and informativeness in the critical evaluation of epidemiological studies, including their exposure assessment methods; improved harmonization of evaluation criteria for the different evidence streams; and a single-step process of integrating evidence on cancer in humans, cancer in experimental animals and mechanisms for reaching overall evaluations. In all, the updated Preamble underpins a stronger and more transparent method for the identification of carcinogenic hazards, the essential first step in cancer prevention. (shrink)

I Propose to re-explore here some aspects of a very shop-worn question: ‘Was Hobbes in any sense an atheist?’ Three centuries ago, Hobbes's personal security in part depended on the way his contemporaries answered this question; today, the validity of several current accounts of his philosophy are similarly bound up with it. These accounts vary extraordinarily, all the way from Polin's confident assertion that ‘ pour qui sait lire entre les lignes, … c'est ľatheísme qui triomphe implicitement ’, to Taylor's (...) equally firm belief that ‘a certain kind of theism is necessary to make [Hobbes's] theory work.’ 1 And now the latest of the Taylorians, Prof. Howard Warrender, has published his book The Political Philosophy of Hobbes , in which Hobbes's statements regarding the place of God are again treated as an essential part of his theory; and the charge explicitly made, that there are no sound grounds for regarding them as ‘the product of confusion or pretence on Hobbes's part’.

Researchers disagree over whether preverbal infants have any true understanding of other minds. There seem to be at least two sources of hesitation among researchers. Some doubt that infants have any concepts as sophisticated as that implied by the term ‘intentionality’. Other researchers simply doubt that infants understand anything in a conceptual way. This chapter provides arguments in favour of infants' abilities in both respects. It describes data from one study in which the method itself was designed to assess conceptual (...) representations abstracted away from perception-action systems. (shrink)

This article examines infant attachment styles from the perspective of cognitive and emotional subjectivity. We review new data that show that individual differences in infants’ attachment behaviors in the traditional Strange Situation are related to (a) infants’ subjective construals of infant—caregiver interactions, (b) their attention to emotional expressions, and (c) polymorphisms in the oxytocin receptor (OXTR) gene. We use these findings to argue that individual differences in infants’ attachment styles reflect, in part, the subjective outcomes of objective experience as filtered (...) through genetic biases in socioemotional information processing.

We examined the effects of three different training conditions, all of which involve the motor system, on kindergarteners’ mental transformation skill. We focused on three main questions. First, we asked whether training that involves making a motor movement that is relevant to the mental transformation—either concretely through action or more abstractly through gestural movements that represent the action —resulted in greater gains than training using motor movements irrelevant to the mental transformation. We tested children prior to training, immediately after training, (...) and 1 week after training, and we found greater improvement in mental transformation skill in both the action and move-gesture training conditions than in the point-gesture condition, at both posttest and retest. Second, we asked whether the total gain made by retest differed depending on the abstractness of the movement-relevant training, and we found that it did not. Finally, we asked whether the time course of improvement differed for the two movement-relevant conditions, and we found that it did—gains in the action condition were realized immediately at posttest, with no further gains at retest; gains in the move-gesture condition were realized throughout, with comparable gains from pretest-to-posttest and from posttest-to-retest. Training that involves movement, whether concrete or abstract, can thus benefit children's mental transformation skill. However, the benefits unfold differently over time—the benefits of concrete training unfold immediately after training ; the benefits of more abstract training unfold in equal steps immediately after training and during the intervening week with no additional training. These findings have implications for the kinds of instruction that can best support spatial learning. (shrink)

In this paper, we explore whether the ethical positions of students are firmly entrenched when they enter college, or do they change due to maturity, experience to ethical discussions in coursework, work experience, or a combination of factors. This study compared the ethical attitudes of freshmen and junior accounting majors, and graduate MBA students when confronted with two ethical dilemmas. Undergraduates were found to be more justice oriented than their MBA counterparts, who were more utilitarian in their ethical approach. While (...) males tended to be more utilitarian, they were also more tentative and neutral in their responses. Females expressed more definite ethical positions than males when assessing specific ethical behaviors. Prior exposure to ethics via coursework or employment did not significantly affect ethical attitudes. (shrink)

Three visual habituation studies using abstract animations tested the claim that infants’ attachment behavior in the Strange Situation procedure corresponds to their expectations about caregiver–infant interactions. Three unique patterns of expectations were revealed. Securely attached infants expected infants to seek comfort from caregivers and expected caregivers to provide comfort. Insecure-resistant infants not only expected infants to seek comfort from caregivers but also expected caregivers to withhold comfort. Insecure-avoidant infants expected infants to avoid seeking comfort from caregivers and expected caregivers to (...) withhold comfort. These data support Bowlby’s (1958) original claims—that infants form internal working models of attachment that are expressed in infants’ own behavior. (shrink)

Work with people with Williams syndrome is reviewed relative to Atran's claim that the universality of taxonomic rank in the animal and plant domains derives from a biological construal of generic species. From this work it is argued that a biological construal of animals is not necessary for the construction of the adult taxonomy of animals and therefore that the existence of an animal (or plant) taxonomy cannot be taken as evidence of a biological domain.

Through an analysis of the interconnections or lack thereof between gender and epistemology, I present Cristina García's The Agüero Sisters as a text of Latina feminist philosophy. First, I use the works of Linda Alcoff and Walter Mignolo to illustrate the political nature of epistemology and how women and people of color in particular are disenfranchised from such a political endeavor. Then I examine the connections among the concepts of origin, absence, inheritance, and knowledge-construction in García's novel to further a (...) critique of standard epistemology and point to an emphasis on reconnection with feminine and maternal knowledge for this text's female characters. Moreover, a depiction and elaboration of María Lugones's ideas of the “coloniality of gender” and “decolonial feminism” in this novel augments this critical examination of epistemology and places emphasis on women as knowledge-producers.

In this article, we review approaches to modeling a connection between spatial and mathematical thinking across development. We critically evaluate the strengths and weaknesses of factor analyses, meta-analyses, and experimental literatures. We examine those studies that set out to describe the nature and number of spatial and mathematical skills and specific connections between these abilities, especially those that included children as participants. We also find evidence of strong spatial-mathematical connections and transfer from spatial interventions to mathematical understanding. Finally, we map (...) out the kinds of studies that could enhance our understanding of the mechanisms by which spatial and mathematical processing are connected and the principles by which mathematical outcomes could be enhanced through spatial training in educational settings.

Variability in the symptom experience in patients diagnosed with chronic conditions may be related to social determinants of health (SDoH). The purpose of this critical review was to (1) summarize the existing literature on SDoH and symptom clusters (i.e., multiple, co‐occurring symptoms) in patients diagnosed with common chronic conditions, (2) evaluate current variables and measures used to represent SDoH, (3) identify gaps in the evidence base, and (4) provide recommendations for the incorporation of SDoH into future symptom cluster research. We (...) identified 118 articles including information on SDoH in chronic condition symptom cluster research. Articles primarily focused on cancer populations. Few articles had the explicit purpose of investigating relationships between SDoH and symptom clusters, and the inclusion of SDoH was often limited to variables used to describe samples. Future studies should be designed to “move beyond Table 1” in their utilization of SDoH as variables and examine relationships between SDoH and symptom clusters. Attention should be paid to the appropriateness of measures being used to collect information on SDoH, and analysis methods that estimate causal connections between variables should be considered. Research regarding the relationship of SDoH with symptom clusters in patients with chronic conditions has the potential to reveal mechanisms of symptom disparities and guide changes to alleviate these disparities.

Diagnosable individuals, caregivers, and clinicians typically embrace a biological conception of attention-deficit/hyperactivity disorder (ADHD), finding that medical treatment is beneficial. Scientists study ADHD phenomenology, interventions to ease symptoms, and underlying mechanisms, often with an aim of helping diagnosed people. Yet current understanding of ADHD, jointly influenced by science and society, has an unintended downside. Scientific and social influences have embedded negative values in the ADHD concept, and have simultaneously dichotomized ADHD diagnosable from non-diagnosable individuals. In social settings insistent on certain (...) types of success, the negative values associated with the diagnostic category are attributed to people in the dichotomized "ADHD" group. Devaluation, institutional restrictions on "success" definitions and endpoints, and limited options for achieving success jointly constitute institutionalized intolerance of ADHD. (shrink)

This book is a critically informed challenge to the traditional histories of rhetoric and to the current emphasis on Aristotle and Plato as the most significant classical voices in rhetoric.

Thomas & Karmiloff- Smith show that the assumption of residual normality does not hold in connectionist simulations, and argue that RN has been inappropriately applied to childhood disorders. We agree. However, we suggest that the RN hypothesis may never have been fully viable, either empirically or computationally.

Given the proliferation of research regarding the ethical development of students in general, and business students in particular, it is difficult to draw conclusions from the contradictory results of many studies. In this meta-analysis of empirical studies from 1985 through 1994, the relationships of gender, age and undergraduate major to the ethical attitudes and behavior of business students are analyzed. The results indicate that female students exhibit stronger ethical attitudes than males. The same is also true for older versus younger (...) students. However, the relationship with undergraduate major is still difficult to interpret. (shrink)

1 Evidence-based policy requires researchers to provide the answers to ecological questions that are of interest to policy makers. To find out what those questions are in the UK, representatives from 28 organizations involved in policy, together with scientists from 10 academic institutions, were asked to generate a list of questions from their organizations. 2 During a 2-day workshop the initial list of 1003 questions generated from consulting at least 654 policy makers and academics was used as a basis for (...) generating a short list of 100 questions of significant policy relevance. Short-listing was decided on the basis of the preferences of the representatives from the policy-led organizations. 3 The areas covered included most major issues of environmental concern in the UK, including agriculture, marine fisheries, climate change, ecosystem function and land management. 4 The most striking outcome was the preference for general questions rather than narrow ones. The reason is that policy is driven by broad issues rather than specific ones. In contrast, scientists are frequently best equipped to answer specific questions. This means that it may be necessary to extract the underpinning specific question before researchers can proceed. 5 Synthesis and applications. Greater communication between policy makers and scientists is required in order to ensure that applied ecologists are dealing with issues in a way that can feed into policy. It is particularly important that applied ecologists emphasize the generic value of their work wherever possible. (shrink)

This book takes us on a fascinating journey through the world of thought of Miki Kiyoshi, one of Japan s pre-eminent philosophers before the Pacific War, and thus makes us discover the man behind the philosopher.

By drawing on a selection of interviews from the website Engaged Philosophy, this paper highlights the work of philosopher-activists within their classrooms and communities. These philosophers have stepped out of the ivory towers and work directly with media, community and political groups, people in prison; or they encourage their students to engage in activist projects. The variety of approaches presented here shows the many ways philosophically inspired activism can give voice to those who are marginalized, shine a light on injustices, (...) expose the root of social problems, and empower others to seek solutions. This work shows the relevance of philosophy to practical problems and the powerful effects it can have in the world. (shrink)

Abstractβ1,4‐galactosyltransferase is unusual among the glycosyltransferases in that it is found in two subcellular compartments where it performs two distinct functions. In the trans‐Golgi complex, galactosyltransferase participates in oligosaccharide biosynthesis, as do the other glycosyltransferases. On the cell surface, however, galactosyltransferase associates with the cytoskeleton and functions as a receptor for extracellular oligosaccharide ligands. Although we now know much regarding galactosyltransferase function in these two compartments, little is known about how it is targeted to these different sites. By cloning the (...) galactosyltransferase gene products, certain features of the protein have been identified that may be critical for its expression on the cell surface or retention within the Golgi complex. This article discusses recent studies which suggest that a cytoplasmic sequence unique to one galactosyltransferase isoform is required for targeting a portion of this protein to the plasma membrane, enabling it to function as a cell adhesion molecule. These findings allow one to manipulate surface galactosyltransferase expression, either positively or negatively, and perturb galactosyltransferase‐dependent cellular interactions during fertilization and development.

In this essay, I explore the parallel between the historical exclusions of rhetoric from philosophy and of women from fields of rational discourse. After considering the usefulness and limitations of deconstruction for exposing marginalization by hierarchical systems, I explore links between texts of the sophists and feminist proposals for rewriting/rereading history by Cixous, Spivak, and others. I conclude that sophistic rhetoric offers a flexible alternative to philosophy as an intellectual framework for mediating theoretical oppositions among contemporary feminisms.

Social stimuli grab our attention: we attend to them in an automatic and bottom-up manner, and ascribe them a higher degree of saliency compared to non-social stimuli. However, it has rarely been investigated how variations in attention affect the processing of social stimuli, although the answer could help us uncover details of social cognition processes such as action understanding. In the present study, we examined how changes to bottom-up attention affects neural EEG-responses associated with intentional action processing. We induced an (...) increase in bottom-up attention by using hypnosis. We recorded the electroencephalographic µ-wave suppression of hypnotized participants when presented with intentional actions in first and third person perspective in a video-clip paradigm. Previous studies have shown that the µ-rhythm is selectively suppressed both when executing and observing goal-directed motor actions; hence it can be used as a neural signal for intentional action processing. Our results show that neutral hypnotic trance increases µ-suppression in highly suggestible participants when they observe intentional actions. This suggests that social action processing is enhanced when bottom-up attentional processes are predominant. Our findings support the Social Relevance Hypothesis, according to which social action processing is a bottom-up driven attentional process, and can thus be altered as a function of bottom-up processing devoted to a social stimulus.

We argue that Horgan's program for nominalizing science fails, because its translation of quantitative statements destroys the inferential structures of explanations, predictions and retrodictions of nonquantitative scientific facts.

I point out that conceptions of particles as mathematical, or quasi mathematical, entities have a longer history than Resnik notices. I argue that Resnik's attack on the distinction between mathematical and physical entities is not deep enough. The crucial problem for this distinction finds its locus in the numerical indeterminancy of elementary particles. This problem, traced by Heisenberg, emerges from the discovery of antimatter.

The term “effective,” on its own, is honorific but vague. Interventions against serious mental illness may be “effective” at goals as diverse as reducing “apparent sadness” or providing housing. Underexamined use of “effective” and other success terms often obfuscates differences and incompatibilities in interventions, degrees of effectiveness, key omissions in effectiveness standards, and values involved in determining what counts as “effective.” Yet vague use of such success terms is common in the research, clinical, and policy realms, with consequences that negatively (...) affect the care offered to individuals experiencing serious mental illness. A pragmatist-oriented solution to these problems suggests that when people use success terms, they need to explain and defend the goals and supporting values embedded in the terms, asking and answering the questions, “Effective at what? For whom? How effective? And why that goal?” Practical and epistemic standards for effectiveness will likely remain plural for good reasons, but each standard should be well explained and well justified. (shrink)

We tested whether analogical training could help children learn a key principle of elementary engineering—namely, the use of a diagonal brace to stabilize a structure. The context for this learning was a construction activity at the Chicago Children's Museum, in which children and their families build a model skyscraper together. The results indicate that even a single brief analogical comparison can confer insight. The results also reveal conditions that support analogical learning.

The first sexual encounter between Dominique Francon and Howard Roark in The Fountainhead is known as the “rape scene.” From the time of the novel's publication, some readers have found a contradiction between Rand's views on freedom and the violence within the novel. The ambiguity arises from the way in which the scenes leading up to the event are constructed, the sadomasochistic context of the novel, and Rand's views of gender and romantic relationships. Although Rand repeatedly denied that any rape (...) occurred, this article concludes that a rape did occur and that Rand fully intended it to be so. (shrink)

The authors of Habits of the Heart believe that American individualism ?may have grown cancerous?that it may be destroying those social integuments that Tocqueville saw as moderating its more destructive potentialities.?

An alternative explanation for the emergence of the isolated self and the incoherence of moral (...) discourse in American life is presented. Both of these phenomena are viewed as temporary responses to a shift in American character. (shrink)

The question of how actin filaments are attached to membranes is of central importance to an understanding of how actin gives rise to shape and movement in cells. A number of approaches to this question have been taken, but there have been few definitive answers. Some of the limitations of these approaches are discussed, as well as possible avenues for overcoming them.
