Online platforms like Instagram cover potentially distressing imagery with a sensitive-content screen (blurred imagery plus a content warning). Previous research suggests people typically choose to “uncover” and view screened content. In three studies, we investigated whether the presence of screens mitigates the negative emotional impact of viewing content. In Study 1, participants viewed positive and neutral images, and screens (with an option to view the negative images beneath) for a 5-minute period. In Study 2, half the participants saw a grey (...) mask in place of the typical sensitive-content screen. In addition, each image appeared for a fixed period (5 s) and participants had no option to uncover it. Study 3 was like Study 2 except half the participants saw negative images preceded by a sensitive-content screen and half saw negative images without screens. Overall, participants reported a significant increase in state anxiety and negative affect from pre-to post task when they were exposed to sensitive-content screens, whether or not they were also exposed to the negative imagery beneath. Our data suggest sensitive-content screens cause negative responses – state anxiety and negative affect – that do not translate to an emotional benefit when people view negative content. (shrink)

Warning research participants and patients about potential risks associated with participation/treatment is a fundamental part of consent. However, such risk warnings might cause negative expectations and subsequent nocebo effects (i.e., negative expectations cause negative outcomes) in participants. Because no existing review documents how past research has quantitatively examined nocebo effects – and negative expectations – arising from consent risk warnings, we conducted a pre-registered scoping review (N = 9). We identified several methodological issues across these studies, which in addition to (...) mixed findings, limit conclusions about whether risk warnings cause nocebo effects. (shrink)

Tomasello et al. propose that shared intentionality is a uniquely human ability. In light of this, we discuss several cultural behaviors that seem to result from a motivation to share experiences with others, suggest evidence for coordination and collaboration among chimpanzees, and cite recent findings that counter the argument that the predominance of emulation in chimpanzees reflects a deficit in intention reading.

Let Q be an equivalence relation whose equivalence classes, denoted Q[x], may be proper classes. A function L defined on Field(Q) is a labelling for Q if and only if for all x,L(x) is a set and L is a labelling by subsets for Q if and only if BG denotes Bernays-Gödel class-set theory with neither the axiom of foundation, AF, nor the class axiom of choice, E. The following are relatively consistent with BG. (1) E is true but there (...) is an equivalence relation with no labelling.(2) E is true and every equivalence relation has a labelling, but there is an equivalence relation with no labelling by subsets.

This handbook presents a comprehensive introduction to the core areas of philosophy of education combined with an up-to-date selection of the central themes. It includes 95 newly commissioned articles that focus on and advance key arguments; each essay incorporates essential background material serving to clarify the history and logic of the relevant topic, examining the status quo of the discipline with respect to the topic, and discussing the possible futures of the field. The book provides a state-of-the-art overview of philosophy (...) of education, covering a range of topics: Voices from the present and the past deals with 36 major figures that philosophers of education rely on; Schools of thought addresses 14 stances including Eastern, Indigenous, and African philosophies of education as well as religiously inspired philosophies of education such as Jewish and Islamic; Revisiting enduring educational debates scrutinizes 25 issues heavily debated in the past and the present, for example care and justice, democracy, and the curriculum; New areas and developments addresses 17 emerging issues that have garnered considerable attention like neuroscience, videogames, and radicalization. The collection is relevant for lecturers teaching undergraduate and graduate courses in philosophy of education as well as for colleagues in teacher training. Moreover, it helps junior researchers in philosophy of education to situate the problems they are addressing within the wider field of philosophy of education and offers a valuable update for experienced scholars dealing with issues in the sub-discipline. Combined with different conceptions of the purpose of philosophy, it discusses various aspects, using diverse perspectives to do so.

Previous studies have shown that children retreat from argument‐structure overgeneralization errors (e.g., *Don’t giggle me) by inferring that frequently encountered verbs are unlikely to be grammatical in unattested constructions, and by making use of syntax‐semantics correspondences (e.g., verbs denoting internally caused actions such as giggling cannot normally be used causatively). The present study tested a new account based on a unitary learning mechanism that combines both of these processes. Seventy‐two participants (ages 5–6, 9–10, and adults) rated overgeneralization errors with higher (...) (*The funny man’s joke giggled Bart) and lower (*The funny man giggled Bart) degrees of direct external causation. The errors with more‐direct causation were rated as less unacceptable than those with less‐direct causation. This finding is consistent with the new account, under which children acquire—in an incremental and probabilistic fashion—the meaning of particular constructions (e.g., transitive causative = direct external causation) and particular verbs, rejecting generalizations where the incompatibility between the two is too great.

BackgroundThere is increasing need for peer reviewers as the scientific literature grows. Formal education in biostatistics and research methodology during residency training is lacking. In this pilot study, we addressed these issues by evaluating a novel method of teaching residents about biostatistics and research methodology using peer review of standardized manuscripts. We hypothesized that mentored peer review would improve resident knowledge and perception of these concepts more than non-mentored peer review, while improving review quality.MethodsA partially blinded, randomized, controlled multi-center study (...) was performed. Seventy-eight neurology residents from nine US neurology programs were randomized to receive mentoring from a local faculty member or not. Within a year, residents reviewed a baseline manuscript and four subsequent manuscripts, all with introduced errors designed to teach fundamental review concepts. In the mentored group, mentors discussed completed reviews with residents. Primary outcome measure was change in knowledge score between pre- and post-tests, measuring epidemiology and biostatistics knowledge. Secondary outcome measures included level of confidence in the use and interpretation of statistical concepts before and after intervention, and RQI score for baseline and final manuscripts.ResultsSixty-four residents (82%) completed initial review with gradual decline in completion on subsequent reviews. Change in primary outcome, the difference between pre- and post-test knowledge scores, did not differ between mentored (−8.5%) and non-mentored (−13.9%) residents (p = 0.48). Significant differences in secondary outcomes (using 5-point Likert scale, 5 = strongly agree) included mentored residents reporting enhanced understanding of research methodology (3.69 vs 2.61; p = 0.001), understanding of manuscripts (3.73 vs 2.87; p = 0.006), and application of study results to clinical practice (3.65 vs 2.78; p = 0.005) compared to non-mentored residents. There was no difference between groups in level of interest in peer review (3.00 vs 3.09; p = 0.72) or the quality of manuscript review assessed by the Review Quality Instrument (RQI) (3.25 vs 3.06; p = 0.50).ConclusionsWe used mentored peer review of standardized manuscripts to teach biostatistics and research methodology and introduce the peer review process to residents. Though knowledge level did not change, mentored residents had enhanced perception in their abilities to understand research methodology and manuscripts and apply study results to clinical practice.

Importance Informed consent is essential to ethical, rigorous research and is important to recruitment and retention in cancer trials.Objective To examine cancer clinical trial (CCT) participants’ perceptions of informed consent processes and variations in perceptions by cancer type.Design and Setting and Participants Cross-sectional survey from mixed-methods study at National Cancer Institute–designated Northeast comprehensive cancer center. Open-ended and forced-choice items addressed: (1) enrollment and informed consent experiences and (2) decision-making processes, including risk-benefit assessment. Eligibility: CCT participant with gastro-intestinal or genitourinary, hematologic-lymphatic (...) malignancies, lung cancer, and breast or gynecological cancer (N = 334).Main Outcome Measures Percentages satisfied with consent process and information provided; and assessing participation’s perceptions of risks/benefits. Multivariable logistic or ordinal regression examined differences by cancer type.Results Most patient-participants felt well informed by the consent process (more than 90% overall and by cancer type) and. most (87.4%) reported that the consent form provided all the information they wanted, although nearly half (44.8%) reported that they read the form somewhat carefully or less. More than half (57.9%) said that talking to research staff (i.e., the consent process) had a greater impact on participation decisions than reading the consent form (2.1%). A third (31.1%) were very sure of joining in research studies before the informed consent process (almost half of lung cancer patients did—47.1%). Most patients personally assessed the risks and benefits before consenting. However, trust in physicians played an important role in the decision to enroll in CCT.Conclusions and Relevance Cancer patients rely less on written features of the informed consent process than on information obtained from the research staff and their own physicians. Research should focus on information and communication strategies that support informed consent from referring physicians, researchers, and others to improve patient risk-benefit assessment and decision-making.

This paper examines the advent of the Web as a critical media tool in the promotion and sale of goods to consumers and the ethical questions it raises that are issues of public policy. We examine four traditional ethical rationales that guide organizational decision-making – utilitarianism, distributive justice, moral rights of man and relativism, further characterized as "ends-based", "equity-based", "rules-based" and "comparison-based" rationales – and we apply them to four moral dilemmas attributed to the proliferation of dot.com companies as they (...) relate to consumer welfare. We find that ethical rationale in the New Media is largely non-existent, and where it exists, it is primarily reactive and driven by utilitarian or relativistic reasoning. We attribute this condition to the newness of the industry and to its economic context, representing, as it does, many characteristics embodied in the concept of the "perfect market." We offer some remedies to improve ethical conduct by e-business. (shrink)

It is, I think, interesting to compare the views of E. F. Schumacher and J. M. Keynes on the ethical aspects of economics – both the economic systems of which they were a part and economics as a subject. Both agreed that economics (as commonly understood and taught) applied to only a limited sphere of life. They agreed about the role of profits, the market and the love of money. And they both believed that there was much more to life (...) than getting and spending. For Keynes, economic activity was the means to bring society to a position where the good life could be enjoyed. Schumacher was even more ambitious: he thought economic activity should be made part of the good life. (shrink)

The National Library of Finland and the Von Wright and Wittgenstein Archives at the University of Helsinki keep the collected correspondence of Georg Henrik von Wright, Wittgenstein’s friend and successor at Cambridge and one of the three literary executors of Wittgenstein’s Nachlass. Among von Wright’s correspondence partners, Elizabeth Anscombe and Rush Rhees are of special interest to Wittgenstein scholars as the two other trustees of the Wittgenstein papers. Thus, von Wright’s collections held in Finland promise to shed light on the (...) context of decades of editorial work that made Wittgenstein’s later philosophy available to all interested readers. In this text, we present the letters which von Wright received from Anscombe and Rhees during the first nine months after Wittgenstein’s death. This correspondence provides a vivid picture of the literary executors as persons and of their developing relationships. The presented letters are beautiful examples of what the correspondence as a whole has to offer; it depicts – besides facts of editing – the story of three philosophers, whose conversing voices unfold the human aspects of inheriting Wittgenstein’s Nachlass. Their story does not only deal with editing the papers of an eminent philosopher, but with the attempt to do justice to the man they knew, to his philosophy and to his wishes for publication.

My thesis explores the possibility that the wrongful intentions principle might not apply in certain deterrent situations. WIP states that if it is wrong to do something under certain conditions, it is wrong to intend to do it should those conditions arise. Questions about applications of WIP are frequently raised in discussions about the morality of nuclear deterrence. Some philosophers, such as Gregory Kavka, maintain that in certain situations where gaining deterrence is important, it is morally permissible, and perhaps even (...) obligatory to form a sincere intention to retaliate although retaliation is wrong. ;The rejection of WIP causes paradoxes about relationships between good agents and right actions. Good and rational agents are unable to fulfill obligations to intend wrong, as their unwillingness to do wrong makes intending it impossible. Hence, the paradoxical conclusion that only a corrupt individual can do right in certain situations. ;The conclusion that in certain situations only corrupt agents can do right rests upon rejecting the WIP. I show that WIP applies in all deterrence situations and in all situations, period. Because WIP always applies, there are no situations where goodness and rationality prevent right action. ;Chapter one presents consequentialist and non-consequentialist arguments to the conclusion that actual retaliation against civilian populations is wrong. In chapters two and three I argue that the kinds of situations discussed by Kavka and others doesn't warrant rejecting WIP. I maintain that non-consequentialist theories cannot permit agents to separate questions about intentions from questions about actions. Consequentialism cannot justify rejecting WIP in these situations either. Rejection of WIP implies that a corrupt leader is needed, and consequentialism cannot justify seeking such a leader. Chapter four argues that WIP must apply in all situations because it must be part of any action-guiding theory, either consequentialist or non-consequentialist. Talk of rejecting WIP is incoherent. Hence, because WIP always applies, goodness and rationality will never preclude right action, and whenever performing an action is wrong, intending to perform it is wrong as well. (shrink)

In evolutionary biology changes in population structure are explained by citing trait fitness distribution. I distinguish three interpretations of fitness explanations—the Two‐Factor Model, the Single‐Factor Model, and the Statistical Interpretation—and argue for the last of these. These interpretations differ in their degrees of causal commitment. The first two hold that trait fitness distribution causes population change. Trait fitness explanations, according to these interpretations, are causal explanations. The last maintains that trait fitness distribution correlates with population change but does not cause (...) it. My defense of the Statistical Interpretation relies on a distinctive feature of causation. Causes conform to the Sure Thing Principle. Trait fitness distributions, I argue, do not. *Received July 2009; revised October 2009. †To contact the author, please write to: Department of Philosophy/Institute for the History, Philosophy of Science and Technology, University of Toronto, Victoria College, 91 Charles Street West, Toronto, ON M5S 1K7, Canada; e‐mail: [email protected].

Smith et al. present a model that they suggest may clarify aspects of the phylogenetic distribution of metacognition, based on observation of what they call uncertainty monitoring. Although they suggest that their model is supported by data collected using monkeys and dolphins, their interpretation that nonhuman animal behaviors parallel thought processes in humans may be unwarranted. The model presented by Smith et al. is inconsistent with current theories and empirical findings on the comparative aspects of metacognition. We present three oversights (...) of the model and extend our critique to include a brief discussion of animal self-awareness, as well as current neuropsychological perspectives on metacognitive processing in humans.

Synaesthesia is a condition in which one type of stimulation evokes the sensation of another, as when the hearing of a sound produces photisms, i.e. mental percepts of colours. R is a 20 year old colour blind subject who, in addition to the relatively common grapheme-colour synaesthesia, presents a rarely reported cross modal perception in which a variety of visual stimuli elicit aura-like percepts of colour. In R, photisms seem to be closely related to the affective valence of stimuli and (...) typically bring out a consistent pattern of emotional responses. The present case study suggests that colours might be an intrinsic category of the human brain. We developed an empirical methodology that allowed us to study the subject's otherwise inaccessible phenomenological experience. First, we found that R shows a Stroop effect elicited by photisms despite the fact that he does not show a regular Stroop with real colours. Secondly, by manipulating the colour context we confirmed that colours can alter R's emotional evaluation of the stimuli. Furthermore, we demonstrated that R's auras may actually lead to a partially inverted emotional spectrum where certain stimuli bring out emotional reactions opposite to the normal ones. These findings can only be accounted for by considering R's subjective colour experience or qualia. Therefore the present paper defends the view that qualia are a useful scientific concept that can be approached and studied by experimental methods. (shrink)

The Birkhoff-Maltsev problem asks for a characterization of those lattices each of which is isomorphic to the lattice L(K) of all subquasivarieties for some quasivariety K of algebraic systems. The current status of this problem, which is still open, is discussed. Various unsolved questions that are related to the Birkhoff-Maltsev problem are also considered, including ones that stem from the theory of propositional logics.

Readers assume that commonplace properties of the real world also hold in realistic fiction. They believe, for example, that the usual physical laws continue to apply. But controversy exists in theories of fiction about whether real individuals exist in the story’s world. Does Queen Victoria exist in the world of Jane Eyre, even though Victoria is not mentioned in it? The experiments we report here find that when participants are prompted to consider the world of a fictional individual (...) (“Consider the world of Jane Eyre…”), they are willing to say that a real individual (e.g., Queen Victoria) can exist in the same world. But when participants are prompted to consider the world of a real individual, they are less willing to say that a fictional individual can exist in that world. The asymmetry occurs when we ask participants both if a real person is in the character’s world and if the person would appear there. However, the effect is subject to spatial and temporal constraints. When the person and the character share spatial and temporal settings, interchange is more likely to occur. These results shed light on the author’s implicit contract with the reader, which can license the reader to augment a fictional world with features that the author only implicates as part of the work’s background.

We assume, in the first place, that two kinds of processes occur in nature: the strictly continuous and causal ones, which are governed by the Schrödinger equation and those implying discontinuities, which are ruled by probability laws. In the second place, we adopt a postulate ensuring the statistical sense of conservation laws. These hypotheses allow us to state a rule telling, in principle, in which situations and to which vectors the system's state can collapse, and which are the corresponding probabilities. (...) The way our proposed approach works is illustrated with some examples and with the analysis of the measurement problem. We obtain the exponential decay law. A comparison with other attempts to solve the measurement problem is performed. (shrink)

LetL(K) denote the lattice (ordered by inclusion) of quasivarieties contained in a quasivarietyK and letD 2 denote the variety of distributive (0, 1)-lattices with 2 additional nullary operations. In the present paperL(D 2) is described. As a consequence, ifM+N stands for the lattice join of the quasivarietiesM andN, then minimal quasivarietiesV 0,V 1, andV 2 are given each of which is generated by a 2-element algebra and such that the latticeL(V 0+V1), though infinite, still admits an easy and nice description (...) (see Figure 2) while the latticeL(V 0+V1+V2), because of its intricate inner structure, does not. In particular, it is shown thatL(V 0+V1+V2) contains as a sublattice the ideal lattice of a free lattice with free generators. Each of the quasivarietiesV 0,V 1, andV 2 is generated by a 2-element algebra inD 2. (shrink)
