In this interview Christine M. Korsgaard answers several questions on her particular interpretation of Kant's moral philosophy. More specifically, she dwells on the role of the noumenal/phenomenal distinction for a better understanding of Kant's idea of practical reason, as well as on the compatibility between Aristotelian and Kantian practical reason. In addition, she answers a couple of more general questions on the perspectives and challenges of contemporary ethical theory.

Recent work on receptor molecules and cells used prototypical sweet, salty, sour, bitter, and umami stimuli. Labeled-line coding was supported, but it remains possible that the molecules and cells could respond to other tastants. Studies with other tastants are needed. The sensory message might contain two codes – one for attraction or aversion, the other, across-fiber patterning of stimulus quality.

Este artículo de homenaje a la Profesora Yolanda Ruano se divide en dos partes. En la primera discuto las críticas que ella realizara a mi libro sobre la diosa Fortuna en las que avanzaba su propio análisis de las complejas relaciones entre razón y fortuna en el pensamiento occidental. En la segunda parte, desde el punto de vista del “giro icónico” en humanidades y ciencias sociales, analizo el caso concreto del auge y desaparición de la diosa Fortuna en la iconografía (...) política de la ciudad de Berlín. A lo largo del siglo XIX la diosa Fortuna desaparece de la escena berlinesa y es sustituida por la diosa Niké o Victoria, que popularmente se interpreta como un Ángel de la Victoria. Este es el marco de la infancia de Walter Benjamin, quien más tarde expresará su visión de la historia con un otro ángel completamente distinto, el Angelus Novus de Paul Klee. (shrink)

The purpose of this paper is twofold: firstly, to explore the emotional aspects underlying classroom conflict management, and secondly, to apply these notions to the contrasted analysis of two case studies. Our findings underscore the importance of examining teachers’ emotional regulation to better understand their performance when dealing with conflicts that affect classroom climate. In the final section, we make suggestions for introducing this perspective into initial teacher training through the use of Virtual Reality, a scenario that would allow pre-service (...) teachers to experiment, record and reflect on affective and attitudinal issues that are decisive for effective classroom conflict management.

One cue that may facilitate children's word learning is iconicity, or the correspondence between a word's form and meaning. Some have even proposed that iconicity in the early lexicon may serve to help children learn how to learn words, supporting the acquisition of even noniconic, or arbitrary, word–referent associations. However, this proposal remains untested. Here, we investigate the iconicity of caregivers’ speech to young children during a naturalistic free‐play session with novel stimuli and ask whether the iconicity of caregivers’ speech (...) facilitates children's learning of the noniconic novel names of those stimuli. Thirty‐four 1.5‐2‐year‐olds (19 girls; half monolingual English learners and half bilingual English‐Spanish learners) participated in a naturalistic free‐play task with their caregivers followed by a test of word‐referent retention. We found that caregivers’ use of iconicity, particularly in utterances in which they named the novel stimuli, was associated with the likelihood that children learned that novel name. This result held even when controlling for other factors associated with word learning, such as the concreteness and frequency of words in caregiver speech. Together, the results demonstrate that iconicity not only can serve to help children identify the referent of novel words (as in previous research) but can also support their ability to retain even noniconic word‐referent mappings.

In this article, we present results from a literature review of intrinsic, instrumental, and relational values of nature conducted for the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, as part of the Methodological Assessment of the Diverse Values and Valuations of Nature. We identify the most frequently recurring meanings in the heterogeneous use of different value types and their association with worldviews and other key concepts. From frequent uses, we determine a core meaning for each value type, which is (...) sufficiently inclusive to serve as an umbrella over different understandings in the literature and specific enough to help highlight its difference from the other types of values. Finally, we discuss convergences, overlapping areas, and fuzzy boundaries between different value types to facilitate dialogue, reduce misunderstandings, and improve the methods for valuation of nature's contributions to people, including ecosystem services, to inform policy and direct future research. © 2023 The Author(s).

When a caregiver names objects dominating a child’s view, the association between object and name is unambiguous and children are more likely to learn the object’s name. Children also learn to name things other than solid objects, including nonsolid substances like applesauce. However, it is unknown how caregivers structure linguistic and exploratory experiences with nonsolids to support learning. In this exploratory study of caregivers and children we compare caregiver-child free-play with novel solid objects and novel nonsolid substances to identify the (...) linguistic and exploratory experiences associated with children’s word learning. We found systematic differences in interactions with novel objects, such that children performed more manual actions on solids than nonsolids and caregivers named solids more than nonsolids. Additionally, there was less synchrony between caregivers’ naming and children’s manual and visual exploration of nonsolids than solids. Consistent with prior work, we found that synchronous naming was associated with accurate recognition of solid object names. However, naming synchrony was not associated with recognition of nonsolid substance names or with generalization. Together these findings, though exploratory, suggest the coordination of caregiver-child play can shape what children remember about novel word-object associations for solid objects, but not nonsolid substances.

Bentley et al.--O’Brien bypass the relevance of emotions in decision-making, resulting in a possible over-simplification of behavioral types. We propose integrating emotions, both in the north-south axis (in relation to cognition) as well as in the west-east axis (in relation to social influence), by suggesting a Z axis, in charge of registering emotional depth and involvement.

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)

Food choices are a key determinant of dietary intake, with brain regions, such as the mesolimbic and prefrontal cortex maturing at differential rates into adulthood. More needs to be understood about developmental changes in healthy and unhealthy food perceptions and preference. We investigated how food perceptions and preference vary as a function of age and how food attributes impact age-related changes. One hundred thirty-nine participants completed computerized tasks to rate high-calorie and low-calorie food cues for taste, health, and liking, followed (...) by 100 binary food choices based on each participant’s ratings. Dietary self-control was considered successful when the healthier food was chosen. Self-control success ratio was the proportion of success trials over total number of choices. Beta-weights for health and taste were calculated as each attribute’s influence on food preference. Adiposity measurements included BMI z-score and waist-to-height ratio. High-calorie foods were rated more tasty and less healthy with increasing age. Older participants liked high-calorie foods more, and β-taste was associated with age. Significant age-by-WHtR interactions were observed for health and taste ratings of high-calorie foods, β-taste, and marginally for preference of high-calorie foods. Stratifying by WHtR, we found age-related increases in taste and preference ratings of high-calorie foods in the high WHtR group alone. In contrast, age-related decreases in health ratings of high-calorie foods were significant in the low WHtR group alone. Age and β-taste were significantly associated in the high WHtR group and only marginally significant with low WHtR. Although participants rated low-calorie foods as less tasty and less healthy with increasing age, there was no association between age and preference for low-calorie foods. Participants made faster food choices with increasing age regardless of WHtR, with a significant age-by-WHtR interaction on reaction time. There were no age-related effects in self-control success ratio and β-health. These results suggest that individual differences in age and central adiposity play an important role in preference for high-calorie foods, and a higher importance of food tastiness in food choice may contribute to greater preference for high-calorie foods with increasing age.

There is no doubt that the use of Internet for purchasing products and services has constituted a crucial change in how people go about buying them. In the era of digital transformation, the possibility of accessing information provided by other users about their personal experiences has taken on more weight in the selection and buying processes. On these lines, traditional word-of-mouth has given way to electronic word-of-mouth, which constitutes a major social change. This behavior is particularly relevant in the services (...) area, where potential users cannot in advance assess what is on offer. There is an abundant literature analyzing the effects of eWOM on different variables of interest in this sector. However, little is known about the factors that determine eWOM. Thus, the main objective of the present paper is to analyze the impact of two variables on eWOM. Both of them are crucial for potential customers in the process of finding hotel accommodations and they can motivate people to make such comments. The results demonstrate that these variables truly have a significant impact on whether or not users make comments on line. Moreover, it proved possible to observe certain differences according to the profile of the tourist involved and the destination where the hotel is located. In the current changing environment, this information is of great use for hotel managers in order to design strategies according to the type of guest they wish to attract. (shrink)

In his famous letter to A. N. Prior dated 3 September 1958, Saul Kripke suggested the use of branching time in temporal logic. In this paper, however, it is argued that Prior worked with an idea close to the notion of branching time (‘the big Y’) already the year before he received Kripke’s letter. It is likely that Prior’s findings based on this early study can explain why Prior so quickly accepted the idea of branching time when he received Kripke’s (...) letter. (shrink)

El legado científico filosófico de Max Born, al estar vinculado a la conocida como interpretación ortodoxa de la mecánica cuántica o interpretación de Copenhague, ha sido entendido desde el marco de una filosofía de la ciencia de corte instrumentalista, considerando su interpretación probabilística de la función de onda como la más clara defensa de una postura indeterminista acausal. Frente a este orden de cosas, este artículo pretende lograr dos objetivos. El primero consiste en mostrar cómo la interpretación de Born, a (...) pesar de instaurar de forma definitiva el indeterminismo en el ámbito de la física elemental, no implica el abandono de una explicación causal de los fenómenos físicos. El segundo trata de defender la posibilidad de reivindicar una interpretación "realista" de la labor científica a partir de la noción de "invariantes observaciones" que Born propone, conciliando el aspecto dual de la realidad elemental en favor de su carácter corpuscular y analizando la aporética noción de "probabilidad objetiva" que su interpretación instaura. Max Born's philosophic and scientific legacy is related to the orthodox interpretation of quantum mechanics, which is known as the Interpretation of Copenhague. Therefore Born's statistical interpretation has been considered as defending a positivist philosophy of science. Opposing this idea, this article is intended to face two main questions. The first one deals with the fact that Born's interpretation of wave function, although it settles indeterminism, does not imply the abandonment of causal explanations of physical phenomena The second one is aimed at showing how is it possible to defend a "realistic view" of scientific labour making use of the notion of "invariant observationals" that leads to the reconciliation of wave and corpuscular theories.

BackgroundSevere brain injury is a leading cause of death and disability. Diagnosis and prognostication are difficult, and errors occur often. Novel neuroimaging methods can improve diagnostic and prognostic accuracy, especially in patients with prolonged disorders of consciousness (PDoC). Yet it is currently unknown how family caregivers understand this information, raising ethical concerns that disclosure of neuroimaging results could result in therapeutic misconception or false hope.MethodsTo examine these ethical concerns, we conducted semi-structured interviews with caregivers of patients with PDoC who were (...) enrolled in a concurrent neuroimaging research program designed to detect covert consciousness following severe brain injury. Caregivers held surrogate decision-making status for a patient. Interviews were conducted at two time points for each caregiver. The first interview occurred before the disclosure of neuroimaging results. The second occurred after disclosure. Descriptive analysis was applied to the data of four interview topics: (1) expectations for neuroimaging; (2) reactions to evidence of preserved cognition; (3) reactions to null results; and (4) understanding of the results and study.ResultsTwelve caregivers participated in the study; two caregivers shared surrogate decision-making status for one patient with PDoC. Twenty-one interviews were completed; one caregiver declined to participate in the post-disclosure interview. Three patients with PDoC associated with the study displayed evidence of covert consciousness. Overall, caregivers understood the neuroimaging research and results. Caregivers who received results of covert consciousness were generally pleased. However, there was some variation in expectations and reactions to these data and null results.ConclusionThis study, for the first time, reveals caregiver expectations for and reactions to neuroimaging evidence of covert consciousness in patients with PDoC. Caregivers understood the neuroimaging research and results, casting doubt on speculative ethical concerns regarding therapeutic misconception and false hope. However, disclosure of neuroimaging result could be improved. Pre-disclosure consultations might assist professionals in shaping caregiver expectations. Standardization of disclosure might also improve comprehension of the results. (shrink)

We analyze the dynamics of repeated interaction of two players in the Prisoner's Dilemma under various levels of interdependency information and propose an instance-based learning cognitive model to explain how cooperation emerges over time. Six hypotheses are tested regarding how a player accounts for an opponent's outcomes: the selfish hypothesis suggests ignoring information about the opponent and utilizing only the player's own outcomes; the extreme fairness hypothesis weighs the player's own and the opponent's outcomes equally; the moderate fairness hypothesis weighs (...) the opponent's outcomes less than the player's own outcomes to various extents; the linear increasing hypothesis increasingly weighs the opponent's outcomes at a constant rate with repeated interactions; the hyperbolic discounting hypothesis increasingly and nonlinearly weighs the opponent's outcomes over time; and the dynamic expectations hypothesis dynamically adjusts the weight a player gives to the opponent's outcomes, according to the gap between the expected and the actual outcomes in each interaction. When players lack explicit feedback about their opponent's choices and outcomes, results are consistent with the selfish hypothesis; however, when this information is made explicit, the best predictions result from the dynamic expectations hypothesis.

Automatic control of physiological variables is one of the most active areas in biomedical engineering. This paper is centered in the prediction of the analgesic variables evolution in patients undergoing surgery. The proposal is based on the use of hybrid intelligent modelling methods. The study considers the Analgesia Nociception Index to assess the pain in the patient and remifentanil as intravenous analgesic. The model proposed is able to make a one-step-ahead prediction of the remifentanil dose corresponding to the current state (...) of the patient. The input information is the previous remifentanil dose, the ANI variable and the electromyogram signal. Modelling techniques used are Artificial Neural Networks and Support Vector machines for Regression combined with clustering methods. Both training and validation were done with a real dataset from different patients. Results obtained show the potential of this methodology to calculate the drug dose corresponding to a given analgesic state of the patient. (shrink)

One of the main challenges in medicine is to guarantee an appropriate drug supply according to the real needs of patients. Closed-loop strategies have been widely used to develop automatic solutions based on feedback variables. However, when the variable of interest cannot be directly measured or there is a lack of knowledge behind the process, it turns into a difficult issue to solve. In this research, a novel algorithm to approach this problem is presented. The main objective of this study (...) is to provide a new general algorithm capable of determining the influence of a certain clinical variable in the decision making process for drug supply and then defining an automatic system able to guide the process considering this information. Thus, this new technique will provide a way to validate a given physiological signal as a feedback variable for drug titration. In addition, the result of the algorithm in terms of fuzzy rules and membership functions will define a fuzzy-based decision system for the drug delivery process. The method proposed is based on a Fuzzy Inference System whose structure is obtained through a decision tree algorithm. A four-step methodology is then developed: data collection, preprocessing, Fuzzy Inference System generation, and the validation of results. To test this methodology, the analgesia control scenario was analysed. Specifically, the viability of the Analgesia Nociception Index as a guiding variable for the analgesic process during surgical interventions was studied. Real data was obtained from fifteen patients undergoing cholecystectomy surgery. (shrink)

Introduction Currently, The nature and scope of Clinical Ethics Protocols in Madrid are not well understood.Objectives The main objective is to describe the features of ‘guideline/recommendation’ type CEPs that have been or are being developed by existing Clinical Ethics Committees in Madrid. Secondary objectives include characterisation of those CECs that have been the most prolific in reference to CEP creation and implementation and identification of any trends in future CEP development.Methods We collected CEPs produced and in process by CECs accredited (...) in the public hospitals in Madrid, Spain, from 1996 to 2008.Results CECs developed 30 CEPs, with 10 more in process. The most common topic is refusal of treatment . If CEPs addressing terminal illness, Do-Not-Resuscitate orders and advance directives are placed into a separate ‘ethical problems at the end of life’ category, this CEP subject emerges as the most common . There is a relationship between the age of the CEC and the development of CEPs . CECs now seem to be more likely to engage in CEP development.Conclusions The CECs in Madrid, Spain, have developed a significant number of CEPs and there is a trend towards continued development. The most frequent topics are ethical problems at the end of life and refusal of treatment by the patient. (shrink)

It was carried out in the period of September 2005 to June 2007. Different research methods were used: the theoretical ones and the technique for group discussion help to design the course syllabus and the assessment for those teachers that received the course. It was verified that the methodological preparation and performance experience are insufficient to play their role; but they value as very important the contents, the methods and the organization of the course. The authors conclude that the course meets the expectations of training, because it was designed keeping in mind the teachers' functions and their necessities. (shrink)
