Relational reasoning is a complex form of human cognition involving the evaluation of relations between mental representations of information. Prior studies have modified stimulus properties of relational reasoning problems and examined differences in difficulty between different problem types. While subsets of these stimulus properties have been addressed in separate studies, there has not been a comprehensive study, to our knowledge, which investigates all of these properties in the same set of stimuli. This investigative gap has resulted in different findings across (...) studies which vary in task design, making it challenging to determine what stimulus properties make relational reasoning—and the putative formation of mental models underlying reasoning—difficult. In this article, we present the Multidimensional Relational Reasoning Task, a task which systematically varied an array of stimulus properties within a single set of relational reasoning problems. Using a mixed-effects framework, we demonstrate that reasoning problems containing a greater number of the premises as well as multidimensional relations led to greater task difficulty. The MRRT has been made publicly available for use in future research, along with normative data regarding the relative difficulty of each problem. (shrink)

The saga of Ceyx, king of Trachis, begins at Met. 11.266 and continues to 11.748. Ceyx' adventures form the longest single episode in the Metamorphoses , slightly longer than the Phaethon legend . Three metamorphoses take place in the course of the Ceyx narrative. The first is that of Ceyx' brother Daedalion who is transformed into a hawk. The second transformation occurs in the course of the exiled Peleus' visit to Ceyx when a wolf attacks Peleus' cattle and sheep and (...) is eventually turned into stone. The third metamorphosis is that of Ceyx and his wife Alcyone into halcyons. The linking together of these three metamorphoses was entirely an Ovidian invention: it had never been done before. It is therefore important to see the Ceyx story as a whole, as it was put together by Ovid. Attention naturally concentrates on the most interesting episode in it – the Ceyx–Alcyone – but the Daedalion and Peleus episodes are integral parts of the narrative and not separate legends. The story is framed by the contrasting transformations of the two brothers. The fierce and bellicose Daedalion becomes a bird of prey . The gentle and uxorious Ceyx becomes a happily paired halcyon . It is ironic that we first meet Ceyx when he is mourning the transformation of his brother into a bird, since the same end awaits him. The brothers' characters are very different but their fates are similar. Ceyx' dealings with Peleus bring out the king of Trachis' hospitable, peace-loving, godly and husbandly qualities and give us a rounded and detailed picture of his personality to balance the developed character-study of his wife Alcyone which is to follow. The spotlight passes from Ceyx to Alcyone at Met. 11. 410. (shrink)

Neptunus et Apollo dicuntur Troiam muro cinxisse; his rex Laomedon uouit quod regno suo pecoris eo anno natum esset immolaturum. id uotum auaritia fefellit. alii dicunt †parum eum promisisse. The story that Neptune and Apollo together built the walls of Troy for Laomedon is well known from Homer. At the end of their year's service the perfidious king refused to pay the agreed wages. Ovid tells the familiar story in one of his transitional sections in the Metamorphoses. Hyginus' account poses (...) the textual problem indicated above. H. I. Rose comments on ‘parum’ as follows: ‘procul dubio corruptum hoc neque arridet Schmidtii coniectura promsisse. fuitne partum equarum? hoc enim plerumque narratur, equos quos a Ioue accepisset promisisse Laomedontem mercedis nomine…sed Herculi; quod facile ad deos mercennarios transferri potuit; atque non equos sed equas fuisse tradit Apollod. II, 104’. Rose rightly rejects Schmidt's emendation ‘promsisse’. ‘Promisisse’ has every sign of soundness and the difficulty lies, as Rose sees, with ‘parum’. Rose's own conjecture ‘partum equarum’, however, will not do. Apart from the oddity of the expression, one would need a good deal more persuasion than Rose offers to accept that the well-known promise of Zeus' horses which Laomedon made to Hercules was transferred from Hercules to Neptune and Apollo. There is no suggestion anywhere in the sources that Laomedon promised to give Neptune and Apollo the famous horses as payment for building the walls. (shrink)

Herein is provided a brief overview of agent-based modeling , with a particular slant toward its potential as a tool for the theoretical biologist. Of course, its use for experimentalists is obvious; they are, as a group, already using agent-based models to examine contemporary biological questions ranging from molecular processes to evolving ecological landscapes . For the modeler-theoretician, ABMs offer a new tool for thinking about the structure of biological processes, thus creating a conduit for integrative perspective taking between the (...) experimentalist and the theoretician.

Ioannidis [Why most published research findings are false. PLoS Med 2: e124 ] identifies six factors that contribute to explaining why most of the current published research findings are more likely to be false than true, and argues that for many current scientific fields, claimed research findings may often be simply accurate measures of the prevailing bias. In this article, we argue that three “hot” areas in current biological research, viz., agent-based modeling, evolutionary developmental biology , and systems biology, are (...) especially prone to the flaws.

While C. I. Lewis was traditionally interpreted as an epistemological foundationalist throughout his major works, virtually every recent treatment of Lewis's epistemology dissents. But the traditional interpretation is correct: Lewis believed that apprehensions of "the given" are certain independently of support from, and constitute the ultimate warrant for, objective empirical beliefs. This interpretation proves surprisingly capable of accommodating apparently contrary textual evidence. The non-foundationalist reading, by contrast, simply cannot explain Lewis's explicit opposition to coherentism and his insistence that only apprehensions (...) of the given enable us to answer the regress problem -- and so vindicate the possibility of empirical justification.

In this article, I expound and defend an interpretation of Sellars as a metaethical quasi-realist. Sellars analyzes moral discourse in non-cognitivist terms: in particular, he analyzes “ought”-statements as expressions of collective intentions deriving from a collective commitment to provide for the general welfare. But he also endorses a functional-role theory of meaning, on which a statement’s meaning is grounded in its being governed by semantical rules concerning language entry, intra-linguistic, and language departure transitions, and a theory of truth as correct (...) assertibility relative to such semantical rules. On these non-representationalist theories, even though moral statements are expressions of intentions and not fundamentally descriptive, they nevertheless count as assertorically meaningful, and some count as positively true. I further argue that this interpretation is capable not only of explaining Sellars’ explicitly metaethical writings, but also of unifying his scientific realism with his commitment to the ineliminable and indispensable role of the language of intentions: if this linguistic framework does not play an explanatory role, but only an expressive role, this explains both why Sellars’ commitment to it does not contravene his naturalism, as well as why, given the necessity of such language for our practical engagement with the world, the scientific image of humans in the world will only be completed once such language supplements it to enable us to relate practically to it.

Professional identity and competent ethical behaviors of nursing students are commonly developed through curricular inclusion of professional nursing values education. Despite the enactment of this approach, nursing students continue to express difficulty in managing ethical conflicts encountered in their practice. This descriptive correlational study explores the relationships between professional nursing values, self-esteem, and ethical decision making among senior baccalaureate nursing students. A convenience sample of 47 senior nursing students from the United States were surveyed for their level of internalized professional (...) nursing values (Revised Professional Nursing Values Scale), level of self-esteem (Rosenberg’s Self-Esteem Scale), and perceived level of confidence in ethical decision making. A significant positive relationship (p < 0.05) was found between nursing students’ professional nursing values and levels of self-esteem. The results of this study can be useful to nursing educators whose efforts are focused on promoting professional identity development and competent ethical behaviors of future nurses. (shrink)

Pragmatist responses to skepticism about empirical justification have mostly been underwhelming, either presupposing implausible theses like relativism or anti-realism, or else showing our basic empirical beliefs to be merely psychologically inevitable rather than rationally warranted. In this paper I defend a better one: a modified version of an argument by Wilfrid Sellars that we are pragmatically warranted in accepting that our perceptual beliefs are likely to be true, since their likely truth is necessary for the satisfaction of our goal of (...) effective agency. On the version of the argument I defend, the great good for human life of control over our empirical circumstances renders our goal of effective agency reasonable. But only if our perceptual beliefs are likely to be true—and only if we accept that this is so, assuming it as a premise for inference and a guide for action—will the success of our actions be due to our effective agency, not mere luck. Since we’re warranted in taking the necessary means to our reasonable ends, we’re warranted in accepting that our perceptual beliefs are generally justified, and so that skepticism about empirical justification is false.

We study 944 shareholder proposals submitted to 343 U.S. firms on climate change issues during 2009–2022. We use logistic and two-stage regression to estimate the propensity for a firm to be targeted or subjected to a vote at the annual general meeting and, for voted proposals, the determinants of that vote. We also examine whether climate-related proposals affect investor returns and how they relate to firms’ future environmental performance and greenhouse gas emissions. Compared to a matched sample, we first find (...) that activists target larger, more carbon-intensive, and less R&D-active firms. Second, voting likelihood is higher for firms with repeated and operations-related proposals and lower pre-proposal environmental ratings. By contrast, disclosure-related proposals are likelier to be negotiated and withdrawn. Third, repeated and operations-related proposals receive higher votes in favor, whereas votes on carbon-intensive firms do not. Fourth, building on the theory that investors act as if they distinguish among the different shareholder proposals based on the expected cost to the firm, we find evidence to support this idea. We find that investors respond negatively to ex-ante costlier proposals, such as those that relate to emissions reduction and target carbon-intensive firms. Fifth, targets’ future environmental performance rating is almost twenty percent higher after a proposal than before compared to the matched sample, whereas emissions do not budge appreciably.

Many have taken Sellars’s critique of empiricism in “Empiricism and the Philosophy of Mind” (EPM) to be aimed at his teacher C. I. Lewis. But if so, why do the famous arguments of its opening sections carry so little force against Lewis’s views? Understandably, some respond by denying that Lewis’s epistemology is among the positions targeted by Sellars. But this is incorrect. Indeed, Sellars had earlier offered more trenchant (if already familiar) critiques of Lewis’s epistemology. What is original about EPM (...) is that it criticizes empiricist positions like Lewis’s not because of their foundationalism, but because of their psychologism about meaning. Since psychologism turns out to be unacceptable by Lewis’s own lights, EPM has a compelling (if implicit) critique of Lewis to offer after all, one that strikes at the heart of his philosophical system.

This paper presents the results of optical interferometry experiments in which the phase of photons in one arm of a Mach-Zehnder interferometer is modified by applying a transverse constriction. An equivalent quantum interferometry experiment using neutron de Broglie waves is discussed in which the observed phase shift is in the spirit of the force-free phase shift of the Aharonov-Bohm effects. In the optical experiments the experimental results are in excellent agreement with predictions.

Despite the growing popularityof farmers' markets (FMs) across the UnitedStates, the experiences and perspectives offarmers who sell at markets have received verylittle research attention. This study describesthe views of 18 farmers from Upstate New Yorkon the importance of FMs as part of theirlifestyle and livelihood, the challenges theyface selling at markets, and their conceptionsof ideal FMs. Through in-depth, semi-structuredinterviews, farmers expressed economic andsocial motivations for selling at FMs; socialbenefits from interacting with customers; andthe challenges they faced as small-scalefarmers and sellers, (...) including extra-marketcompetition, uncooperative and problematicmarket vendors, rising farm input costs, andchanging consumer trends. Farmers alsodiscussed personal values associated withselling at FMs, such as pride in raising andmarketing one's own products, working togetherwith other farmer-vendors, and providingcustomers with honest information. Visions ofideal FMs were varied among farmers, but therewas general agreement that FMs should provide adiversity of products to attract customers andeducational opportunities for the public tolearn more about FMs and local produce. Theinterdependence of FM farmers was a majoremergent theme across interviews. Findingssuggested that market experiences of FMfarmers, including economic success, are notonly contingent on personal effort, but canalso be affected by the work of fellow vendors.Future research may look to further explore howFM farmers and other vendors interact ascooperative and competitive social and economicunits. At the community level, FM leadershipshould continue to focus on the experiences andperspectives of farmers and other marketvendors, in addition to identifying ways forenhancing cooperative FM enterprises.

Food waste comprises a significant portion of the waste stream in industrialized countries, contributing to ecological damages and nutritional losses. Guided by a systems approach, this study quantified food waste in one U.S. County in 1998–1999. Publications and personal interviews were used to quantify waste from food production, processing, distribution, and consumption. Approximately 10,205 tons of food waste was generated annually in this community food system. Of all food waste, production waste comprised 20%, processing 1%, distribution 19%, and 60% of (...) food waste was generated by consumers. Less than one-third (28%) of total food waste was recovered via composting (25%) and food donations (3%), and over 7,000 tons (72%) were landfilled. More than 8.8 billion kilocalories of food were wasted, enough to feed county residents for 1.5 months. This case study offers an example of procedures to quantify and compare food waste across a whole community food system. (shrink)

Watch a three-year-old play. As she enacts Ariel and Barbie’s judo match over which will marry Prince, or trudges through the living room scolding a pink polka-dotted bunny in a stroller, or explains to you that four-foot-tall Dora is in time out because she’s been hitting the other kids with a hammer—well, you may be laughing, but chances are she’s not. When you’re three, play is a serious, cathartic process aimed at sorting out and bringing under tenuous control the often (...) overwhelming emotional cues thrown at you each day. Children tease out what scares them—say, jealousy, or blame, or violent anger—and nail it down in particular scenarios that allow them to follow a feeling to its natural conclusions .. (shrink)

This volume addresses persistent issues in the preservice and continuing education of teachers. Attention is focused upon perspectives on teacher education that differ significantly from those that have characterized views of this field in the past. Among developments that provide the current context for teacher education are the movement for standards, the emphasis upon inquiry in the classroom, increased expectations for teachers' participation in curriculum development, constructivism and the cognitive revolution, and professional development schools. These and other matters receive the (...) attention of a distinguished group of scholars and practitioners in the field. (shrink)

This book sorts out the confusion created by the use of the term "postmodern" in relation to widely divergent theological positions. Four different types of postmodern theology are distinguished in the preface: constructive, deconstructive, liberationist, and conservative. Two forms of each type are discussed in the book. Writing from a constructive, postmodern perspective, the authors enter into dialogue with the deconstructive postmodernism of Mark C. Taylor and Jean-François Lyotard, with the liberationist postmodernism of Harvey Cox and Cornel West, and with (...) the conservative postmodernism of George William Rutler and John Paul II. (shrink)
