Intuitively, the accuracy of initial word-referent mappings should be positively correlated with the outcome of learning. Yet recent evidence suggests an inverse effect of initial accuracy in adults, whereby greater accuracy of initial mappings is associated with poorer outcomes in a cross-situational learning task. Here, we examine the impact of initial accuracy on 4-year-olds, 10-year-olds, and adults. For half of the participants most word-referent mappings were initially correct and for the other half (...) most mappings were initially incorrect. Initial accuracy was positively related to learning outcomes in 4-year-olds, had no effect on 10-year-olds' learning, and was inversely related to learning outcomes in adults. Examination of item learning patterns revealed item interdependence for adults and 4-year-olds but not 10-year-olds. These findings point to a qualitative change in language learning processes over development. (shrink)

Meta-accuracy of first impressions on the Internet has the potential to shape subsequent interactions. Aiming to enhance understanding of the underlying perceptual dimensions, the contribution of social competence, and the existence of positive/negative bias in first impressions’ meta-accuracy online, we conducted a study in a simulated asynchronous social-media-type setting. Target participants uploaded a selfie, wrote a short description of themselves, provided estimates of how warm and competent they believed others would find them based on their selfies and texts, (...) and completed two social competence questionnaires. Perceiver participants assessed the warmth and competence of the selfies and texts as well. Meta-accuracy was measured as the absolute difference between metaperception and others’ perception. Through correlational analyses, we confirmed that meta-accuracy of first impressions on the Internet aligned with the universal dimensions of social cognition, found sporadic evidence for the positive association between meta-accuracy and social competence, and showed that meta-accuracy for specific Internet expressive means varied with varying proficiency in these means. Through t-tests, we demonstrated positive meta-accuracy bias for selfies along the warmth dimension and negative bias for text along the competence dimension. Overall, our results suggest the primacy of warmth and uniqueness of the male targets-female perceivers combination for meta-accuracy on the Internet. Our findings expand knowledge about first impressions’ meta-accuracy on the Internet. (shrink)

In Bayesian epistemology, the problem of the priors is this: How should we set our credences (or degrees of belief) in the absence of evidence? That is, how should we set our prior or initial credences, the credences with which we begin our credal life? David Lewis liked to call an agent at the beginning of her credal journey a superbaby. The problem of the priors asks for the norms that govern these superbabies. -/- The Principle of Indifference gives (...) a very restrictive answer. It demands that such an agent divide her credences equally over all possibilities. That is, according to the Principle of Indifference, only one initial credence function is permissible, namely, the uniform distribution. In this paper, we offer a novel argument for the Principle of Indifference. I call it the Argument from Accuracy. (shrink)

The initial successes in recent years in harnessing machine learning technologies to improve medical practice and benefit patients have attracted attention in a wide range of healthcare fields. Particularly, it should be achieved by providing automated decision recommendations to the treating clinician. Some hopes placed in such ML-based systems for healthcare, however, seem to be unwarranted, at least partially because of their inherent lack of transparency, although their results seem convincing in accuracy and reliability. Skepticism arises when the (...) physician as the agent responsible for the implementation of diagnosis, therapy, and care is unable to access the generation of findings and recommendations. There is widespread agreement that, generally, a complete traceability is preferable to opaque recommendations; however, there are differences about addressing ML-based systems whose functioning seems to remain opaque to some degree—even if so-called explicable or interpretable systems gain increasing amounts of interest. This essay approaches the epistemic foundations of ML-generated information specifically and medical knowledge generally to advocate differentiations of decision-making situations in clinical contexts regarding their necessary depth of insight into the process of information generation. Empirically accurate or reliable outcomes are sufficient for some decision situations in healthcare, whereas other clinical decisions require extensive insight into ML-generated outcomes because of their inherently normative implications.

It is widely held in contemporary philosophy of mind that states with underived representational content are ipso facto psychological states. This view—the Content View—underlies a number of interesting philosophical projects, such as the attempt to pick out a psychological level of explanation, to demarcate genuinely psychological from non-psychological states, and to limn the class of states with phenomenal character. The most detailed and influential theories of underived representation in philosophy are the tracking theories developed by Fodor, Dretske, Millikan and others. (...) Tracking theorists initially hoped to ‘naturalize’ underived representation by showing that although it is distinctively psychological it is not irreducibly so, yet they ended up developing theories of representation that by their own lights don’t pick out a distinctively psychological phenomenon at all. Burge sets out to develop a theory of underived representation that does pick out a distinctively psychological phenomenon. His theory promises to vindicate the Content View and the various philosophical projects that depend on it. In this paper I argue that Burge’s theory dementalizes representation for the same reason tracking theories do: These theories hold that representations are states with underived accuracy conditions, yet such states are found in all sorts of mindless systems, like plants.

The ability to learn cause–effect relations from experience is critical for humans to behave adaptively — to choose causes that bring about desired effects. However, traditional experiments on experience-based learning involve events that are artificially compressed in time so that all learning occurs over the course of minutes. These paradigms therefore exclusively rely upon working memory. In contrast, in real-world situations we need to be able to learn cause–effect relations over days and weeks, which necessitates long-term memory. 413 participants completed (...) a smartphone study, which compared learning a cause–effect relation one trial per day for 24 days versus the traditional paradigm of 24 trials back- to- back. Surprisingly, we found few differences between the short versus long timeframes. Subjects were able to accurately detect generative and preventive causal relations, and they exhibited illusory correlations in both the short and long timeframe tasks. These results provide initial evidence that experience-based learning over long timeframes exhibits similar strengths and weaknesses as in short timeframes. However, learning over long timeframes may become more impaired with more complex tasks. (shrink)

Insight has been investigated under the assumption that participants solve insight problems with insight processes and/or experiences. A recent trend has involved presenting participants with the solution and analysing the resultant experience as if insight has taken place. We examined self-reports of the aha experience, a defining aspect of insight, before and after feedback, along with additional affective components of insight (e.g., pleasure, surprise, impasse). Classic insight problems, compound remote associates, and non-insight problems were randomly interleaved and presented to participants. (...) Solution feedback increased ratings of aha experience in both insight and non-insight problems, with this result being driven by responses to solutions that were initially incorrectly generated. Ratings of aha for correctly generated solutions decreased after the correct solution was presented. These findings have implications for insight research paradigms as well as informing teaching methods. (shrink)

We question whether Plamondon & Alimi's model is useful in accounting for the nonsymmetrical and multiple-peaked velocity profiles observed in young and elderly subjects for ballistic aiming tasks. For these subjects, both data and observation suggest that a central representation initiates the movement in an appropriate direction but that multiple adjustments are made, both early and late, to achieve spatial accuracy.

Character judgments play an important role in our everyday lives. However, decades of empirical research on trait attribution suggest that the cognitive processes that generate these judgments are prone to a number of biases and cognitive distortions. This gives rise to a skeptical worry about the epistemic foundations of everyday characterological beliefs that has deeply disturbing and alienating consequences. In this paper, I argue that this skeptical worry is misplaced: under the appropriate informational conditions, our everyday character-trait judgments are in (...) fact quite trustworthy. I then propose a mindreading-based model of the socio-cognitive processes underlying trait attribution that explains both why these judgments are initially unreliable, and how they eventually become more accurate.

Previous research on lexical development has aimed to identify the factors that enable accurate initial word-referent mappings based on the assumption that the accuracy of initial word-referent associations is critical for word learning. The present study challenges this assumption. Adult English speakers learned an artificial language within a cross-situational learning paradigm. Visual fixation data were used to assess the direction of visual attention. Participants whose longest fixations in the initial trials fell more often on distracter images (...) performed significantly better at test than participants whose longest fixations fell more often on referent images. Thus, inaccurate initial word-referent mappings may actually benefit learning. (shrink)

The author analyses the reliability and accuracy of the results of sociological research conducted using quota sampling. The author discusses the advantages and disadvantages of using quota samples compared to random samples. The main focus is on the representativeness of the obtained data and the possibility of extrapolating them to the general population.In the problem statement, the author noted that a mechanical method of forming a random sample is most often used to study public opinion in Ukraine. The main (...) feature of this method is to ensure an equal probability of selection of each element of the general population. The author emphasizes that although this method allows for easy calculation of possible errors and analysis of collected information, it has a disadvantage in representing specific groups of the population.To address this problem, the author proposes using an equal probability method of forming quota samples, which allows selecting respondents according to their quotas in the general population, thus providing a more representative model of the studied population. However, in the scientific community, there is no consensus on the use of indicators in forming quota samples, and all existing works remain at the level of theoretical assumptions.The author attempts to empirically substantiate the effectiveness of quota samples through experimentation. The hypothesis of the experiment assumes that the results of studies conducted according to quotas can be extrapolated to the general population with high accuracy and reliability using mathematical and statistical methods. During the experiment, both quota and random samples were used to compare the results.The general population consisted of 489 musical compositions represented in different proportions to eliminate the subjective component from the experiment and provide the opportunity to clearly assess and record the parameters of the initial general population for further comparison with the results of different types of samples. The musical compositions had two parameters: the name of the performer for identification and the duration of the track for digital and statistical evaluation. The analysis was carried out using a specially developed program for statistical data analysis. The collected data allowed for the assessment of the average track duration, median, skewness, standard deviation, and other statistical indicators.The results of the experiment showed that the quota sample provides more accurate results when the quotas are followed during the selection of elements of the general population. The sample obtained by random selection without adhering to quotas showed greater variability in indicators such as mean, median, skewness, and standard deviation relative to the general population. Thus, it was concluded that quota samples have advantages in sociological research, especially when specific groups of the population need to be considered.The author emphasizes the need for further research and improvement of quota sampling methods to enhance the accuracy and reliability of sociological studies, which are important for examining particular social issues.

Although widely studied in other domains, relatively little is known about the metacognitive processes that monitor and control behaviour during reasoning and decision-making. In this paper, we examined the conditions under which two fluency cues are used to monitor initial reasoning: answer fluency, or the speed with which the initial, intuitive answer is produced, and perceptual fluency, or the ease with which problems can be read. The first two experiments demonstrated that answer fluency reliably predicted Feeling of Rightness (...) judgments to conditional inferences and base rate problems, which subsequently predicted the amount of deliberate processing as measured by thinking time and answer changes; answer fluency also predicted retrospective confidence judgments. Moreover, the effect of answer fluency on reasoning was independent from the effect of perceptual fluency, establishing that these are empirically independent constructs. In five experiments with a variety of reasoning problems similar to those of Alter et al., we found no effect of perceptual fluency on FOR, retrospective confidence or accuracy; however, we did observe that participants spent more time thinking about hard to read stimuli, although this additional time did not result in answer changes. In our final two experiments, we found that perceptual disfluency increased accuracy on the CRT, but only amongst participants of high cognitive ability. As Alter et al.’s samples were gathered from prestigious universities, collectively, the data to this point suggest that perceptual fluency prompts additional processing in general, but this processing may results in higher accuracy only for the most cognitively able.

The effective collection and management of personal data of rapidly migrating populations is important for ensuring adequate healthcare and monitoring of a displaced peoples’ health status. With developments in ICT data sharing capabilities, electronic personal health records (ePHRs) are increasingly replacing less transportable paper records. ePHRs offer further advantages of improving accuracy and completeness of information and seem tailored for rapidly displaced and mobile populations. Various emerging initiatives in Europe are seeking to develop migrant‐centric ePHR responses. This paper highlights (...) their importance and benefits, but also identifies a number of significant ethical, legal and social issues (ELSI) and challenges to their design and implementation, regarding (1) the kind of information that should be stored, (2) who should have access to information, and (3) potential misuse of information. These challenges need to be urgently addressed to make possible the beneficial use of ePHRs for vulnerable migrants in Europe. (shrink)

The strap-down inertial navigation system is a commonly used sensor for autonomous underground navigation, which can be used for shearer positioning under a coal mine. During the process of initial alignment, inaccurate or time-varying noise covariance matrices will significantly degrade the accuracy of the initial alignment of the shearer. To overcome the performance degradation of the existing initial alignment algorithm under complex underground environment, a novel adaptive filtering algorithm is proposed by the integration of the strong (...) tracking Kalman filter and the sequential filter for the initial alignment of the shearer with complex underground environment. Compared with the traditional multiple fading factor strong tracking Kalman filter method, the proposed MSTSKF algorithm integrates the advantage of strong tracking Kalman filter and sequential filter, and multiple fading factor and forgetting factor for east and north velocity measurement are designed in the algorithm, respectively, which can effectively weaken the coupling relationship between the different states and increase strong robustness against process uncertainties. The simulation and experiment results show that the proposed MSTSKF method has better initial alignment accuracy and robustness than existing strong tracking Kalman filter algorithm. (shrink)

This paper employs data from a sample of the CEOs and top managers of seventy-nine U.S. companies and non-profit organizations to test hypotheses concerning the effects of the salience of organizational values on the accuracy of top managers’ perceptions of their CEOs’ values and their propensities to project their own values onto their CEOs. Results provide evidence that the salience of organizational values is positively related to both accuracy in subordinates’ perceptions of their superiors’ values and projection of (...) the subordinates’ values onto their superiors. This initially counterintuitive result is explained with reference to contemporary views of projection as a heuristic rather than as a non-normative bias that results in the cognitive distortion of reality.

It has been proposed that individuals with autism spectrum disorder struggle both with response initiation and with response inhibition, both of which are functions of the executive system. Experimental tasks are unlikely pure measures of a single cognitive domain, and in this study we aim at understanding the contributions of response initiation difficulties to possible deficits in inhibitory control in autism. A sample of adults diagnosed with ASD and a control sample participated in this study. To participants it was asked (...) to perform a sentence-completion task with two different condition: Part A—targeting response initiation and Part B—engaging inhibitory processes. Importantly, we have analyzed the B-A latencies that have been proposed for the removal of the response initiation confound effect. Results show that no differences between the groups were found in accuracy measures, either in Part A nor Part B. However, in both conditions autistic participants were significantly slower to respond than the group of participants with typical development. Critically, we show that when subtracting the response times of Part A from Part B no group differences attributable to inhibitory processes remained. With this study we corroborate the existence of difficulties with response initiation in autism and we question the existence of troubles in inhibition per se. (shrink)

Russell's statements in the immediate post-World War II period about war with the Soviet Union have generated considerable controversy. Some commentators interpret his declarations as if he advocated a preventive war against the Soviet Union. To the contrary, Russell advanced a strategy of conditional threat of war with the aim not of provoking war, but of preventing it. However, Russell was unable to satisfy his critics. Despite initial accuracy in his restatements of what he had originally said, Russell (...) erred in later affirmations, lending credence to the erroneous view that he had something to hide. (shrink)

Since the 16th century, assays and screens have been essential for scientific investigation. However, most methods could be significantly improved, especially in accuracy, scalability, and often lack adequate comparisons to negative controls. There is a lack of consistency in distinguishing assays, in which accuracy is the main goal, from screens, in which scalability is prioritized over accuracy. We dissected and modernized the original definitions of assays and screens based upon recent developments and the conceptual framework of the (...) original definitions. All methods have three components: design/measurement, performance, and interpretation. We propose a model of method development in which reproducible observations become new methods, initially assessed by sensitivity. Further development can proceed along a path to either screens or assays. The screen path focuses on scalability first, but can later prioritize analysis of negatives. Alternatively, the assay path first compares results to negative controls, assessing specificity and accuracy, later adding scalability. Both pathways converge on a high‐accuracy and throughput (HAT) assay, like next generation sequencing, which we suggest should be the ultimate goal of all testing methods. Our model will help scientists better select among available methods, as well as improve existing methods, expanding their impact on science. (shrink)

Initially, you judge that p. You then learn that most experts disagree. All things considered, you believe that the experts are probably right. Still, p continues to seem right to you, in some sense. You don’t yet see what, if anything, is wrong with your original reasoning. In such a case, we’ll say that you are ‘inclined’ toward p. This paper explores various roles that this state of inclination can play, both within epistemology and more broadly. Specifically, it will be (...) argued that: (i) inclinations can promote the accuracy of inquiring groups; (ii) they can support rational participation within philosophy despite pervasive disagreement; (iii) they allow us to make sense of an important way in which two people can continue to disagree even after they ‘conciliate’; (iv) inclinations carry information about individuals’ independent judgments and for this reason must be accounted for when updating on the opinions of others; (v) inclinations are connected to understanding in a way that belief is not; (vi) and awareness of the inclination-belief distinction enables us to respond to a provocative challenge purporting to show that critical thinking, or ‘thinking for oneself’, typically reduces expected accuracy and hence should be discouraged.

There is some consensus on the claim that imagination as suppositional thinking can have epistemic value insofar as it’s constrained by a principle of minimal alteration of how we know or believe reality to be – compatibly with the need to accommodate the supposition initiating the imaginative exercise. But in the philosophy of imagination there is no formally precise account of how exactly such minimal alteration is to work. I propose one. I focus on counterfactual imagination, arguing that this can (...) be modeled as simulated belief revision governed by Laplacian imaging. So understood, it can be rationally justified by accuracy considerations: it minimizes expected belief inaccuracy, as measured by the Brier score. (shrink)

To improve the positioning accuracy of industrial robots and avoid using the coordinates of the end effector, a novel kinematic calibration method based on the distance information is proposed. The kinematic model of an industrial robot is established. The relationship between the moving distance of the end effector and the kinematic parameters is analyzed. Based on the results of the analysis and the kinematic model of the robot, the error model with displacements as the reference is built, which is (...) linearized for the convenience of the following identification. The singular value decomposition is used to eliminate the redundant parameters of the error model. To solve the problem that traditional optimization algorithms are easily affected by data noise in high dimension identification, a novel extended Kalman filter and regularized particle filter hybrid identification method is presented. EKF is used in the preidentification of the linearized error model. With the preidentification results as the initial parameters, RPF is used to identify the kinematic parameters of the linearized error model. Simulations are carried out to validate the effectiveness of the proposed method, which shows that the method can identify the error of the parameters and after compensation the accuracy of the robot is improved.

The escalating integration of Artificial Intelligence (AI) in clinical settings carries profound implications for the doctrine of informed consent, presenting challenges that necessitate immediate attention. China, in its advancement in the deployment of medical AI, is proactively engaging in the formulation of legal and ethical regulations.

The study reveals (...) that medical AI poses fundamental challenges to the accuracy, adequacy, and objectivity of information disclosed by doctors, alongside impacting patient competency and willingness to give consent. To enhance adherence to informed consent rules in the context of medical AI, this paper advocates for a shift towards a patient‐centric information disclosure standard, the restructuring of medical liability rules, the augmentation of professional training, and the advancement of public understanding through educational initiatives.

Medical ethics has become an important and recognized component of physician training. There is one area, however, in which medical students receive little guidance. There is practically no discussion of the financial aspects of medical practice. My objective in this paper is to initiate a discussion about the moral dimension of physician billing practices. I argue that physicians should expand their conception of professional responsibility in order to recognize that their moral obligations toward patients include a commitment to honest and (...) forthright billing practices. I argue that physicians should aspire to a standard of clinical accuracy—not legal adequacy—in describing their activities. More generally, physicians should strive to promote an integrity-based professional culture, first and foremost by stigmatizing rather than celebrating creative billing practices, as well as condemning the misguided sense of solidarity that currently makes it taboo for physicians to criticize each other on this score.

This study tested the hypothesis that in the minds of adult religious adherents, acquired beliefs about the extraordinary characteristics of God coexist with, rather than replace, an initial representation of God formed by co-option of the evolved person concept. In three experiments, Christian religious adherents were asked to evaluate a series of statements for which core intuitions about persons and acquired Christian beliefs about God were consistent or inconsistent. Participants were less accurate and slower to respond to inconsistent versus (...) consistent statements, suggesting that the core intuitions both coexisted alongside and interfered with the acquired beliefs. In Experiment 2 when responding under time pressure participants were disproportionately more likely to make errors on inconsistent versus consistent statements than when responding with no time pressure, suggesting that the resolution of interference requires cognitive resources the functioning of which decreases under cognitive load. In Experiment 3 a plausible alternative interpretation of these findings was ruled out by demonstrating that the response accuracy and time differences on consistent versus inconsistent statements occur for God—a supernatural religious entity—but not for a natural religious entity.

In this study I attempt to provide an answer to the question how the Babylonian scholars arrived at their mathematical theory of planetary motion. Although no texts are preserved in which the Babylonians tell us how they did it, from the surviving Astronomical Diaries we have a fairly complete picture of the nature of the observational material on which the scholars must have based their theory and from which they must have derived the values of the defining parameters. Limiting the (...) discussion to system A theory of the outer planets Saturn, Jupiter and Mars, I will argue that the development of Babylonian planetary theory was a gradual process of more than a century, starting sometime in the fifth century BC and finally resulting in the appearance of the first full-fledged astronomical ephemeris around 300 BC. The process of theory formation involved the derivation of long “exact” periods by linear combination of “Goal–Year” periods, the invention of a 360° zodiac, the discovery of the variable motion of the planets and the development of the numerical method to model this as a step function. Longitudes of the planets in the Babylonian zodiac could be determined by the scholars with an accuracy of 1° to 2° from observations of angular distances to Normal Stars with known positions. However, since the sky is too bright at first and last appearances of the planets and at acronychal rising for nearby stars to be visible, accurate longitudes as input for theoretical work could only be determined when the planets were near the stationary points in their orbits. In this study I show that the Babylonian scholars indeed based their system A modeling of the outer planets on planetary longitudes near stations, that their system A models of Saturn and Jupiter provided satisfactory results for all synodic phenomena, that they realized that their system A model of Mars did not produce satisfactory results for the second station so that separate numerical schemes were constructed to predict the positions of Mars at second station from the model at first station, and finally that their system A model for Mars provided quite poor predictions of the longitude of Mars at first and last appearances over large stretches of the zodiac. I further discuss ways in which the parameters of the system A models may have been derived from observations of the outer planets. By analyzing contemporaneous ephemerides from Uruk of four synodic phenomena of Jupiter from the second century BC, I finally illustrate how the Babylonian scholars may have used observations of Normal Star passages of planets to choose the initial conditions for their ephemerides.

We analyzed stable patients’ views regarding synthetic biology in general, the medical application of synthetic biology, and their potential participation in trials of synthetic biology in particular. The aim of the study was to find out whether patients’ views and preferences change after receiving more detailed information about synthetic biology and its clinical applications. The qualitative study was carried out with a purposive sample of 36 stable patients, who suffered from diabetes or gout. Interviews were transcribed verbatim, translated and fully (...) anonymized. Thematic analysis was applied in order to examine stable patients’ attitudes towards synthetic biology, its medical application, and their participation in trials. When patients were asked about synthetic biology in general, most of them were anxious that something uncontrollable could be created. After a concrete example of possible future treatment options, patients started to see synthetic biology in a more positive way. Our study constitutes an important first empirical insight into stable patients’ views on synthetic biology and into the kind of fears triggered by the term “synthetic biology.” Our results show that clear and concrete information can change patients’ initial negative feelings towards synthetic biology. Information should thus be transmitted with great accuracy and transparency in order to reduce irrational fears of patients and to minimize the risk that researchers present facts too positively for the purposes of persuading patients to participate in clinical trials. Potential participants need to be adequately informed in order to be able to autonomously decide whether to participate in human subject research involving synthetic biology. (shrink)

In this paper, I have a twofold aim: First I wish to show to what extent the Husserlian Theory of Intersubjectivity can be relevant for contemporary empirical research and for ancestral wisdom traditions, both in their experiences and in their conceptual tools; and secondly I intend to rely on some empirical results and experiential mystical/practical reports in order to bring about some more refined phenomenological descriptions first provided by Husserl. The first aim will be the main concern here, while the (...) second will only be broached by way of initial steps towards further development. -/- I will proceed in two stages: in the first place I will give some evidence for Husserl's relevance by giving an account of his original conceptions of (a) egoic subjectivity, (b) genetic phenomenology, and (c) lived empathy. In the second place, my purpose is to indicate how much Husserl's view on infants/children, animals/ beasts, mad people/the insane and aliens/foreigners/strangers may be of some interest for scientific empirical conceptions and for practical paths of spiritual self-development. In so doing, I hope to be able (1) to confirm the accuracy of Husserl's own intuitions and analysis, and (2) to suggest some refinements in the way Husserl described such experiences. -/- Throughout this paper I will focus on two main Husserlian discoveries: (1) subjectivity is from the very start intersubjectivity; (2) infants, animals, the insane and aliens are subjects in a full sense, precisely because they are from the very beginning always already intersubjective subjects; besides, they are limit-subjectivities, who compel me in a kind of feedback to enlarge and to deepen my own subjectivity.

We explore the nature of forgetting in a corpus of 125,000 students learning Spanish using the Rosetta Stone® foreign-language instruction software across 48 lessons. Students are tested on a lesson after its initial study and are then retested after a variable time lag. We observe forgetting consistent with power function decay at a rate that varies across lessons but not across students. We find that lessons which are better learned initially are forgotten more slowly, a correlation which likely reflects (...) a latent cause such as the quality or difficulty of the lesson. We obtain improved predictive accuracy of the forgetting model by augmenting it with features that encode characteristics of a student's initial study of the lesson and the activities the student engaged in between the initial and delayed tests. The augmented model can predict 23.9% of the variance in an individual's score on the delayed test. We analyze which features best explain individual performance. (shrink)

Ensemble musicians play in synchrony despite expressively motivated irregularities in timing. We hypothesized that synchrony is achieved by each performer internally simulating the concurrent actions of other ensemble members, relying initially on how they would perform in their stead. Hence, musicians should be better at synchronizing with recordings of their own earlier performances than with others’ recordings. We required pianists to record one part from each of several piano duets, and later to play the complementary part in synchrony with their (...) own or others’ recordings. The pianists were also asked to identify their own recordings. The pianists were better at synchronizing with their own than with others’ performances, and they were able to recognize their own recordings. Furthermore, synchronization accuracy and recognition were correlated: Pianists who were relatively accurate at synchronizing with their own performances were also good at recognizing them. Thus, action simulation may underlie both synchronization and self-recognition. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Cynthia B. Cohen THE TRIALS OF SOCRATES AND JOSEPH K. No two trials could have been more unlike than those of Socrates and Joseph K. As portrayed in Plato's Apology,' Socrates was the conscience of Athens, a thoughtful and courageous man whose life was devoted to the pursuit of wisdom. He challenged others to examine themselves and to transform themselves into lovers of truth and goodness. This gadfly of (...) Athens was put on trial by those whom he had stung and was dispatched with a final slap. He died the bravest, wisest, and most upright man of his time. By contrast, Joseph K., the protagonist of Kafka's novel, The Trial, was an ordinary bank clerk locked into a life of unreflective routine. His arrest one day by the agents of a Court he could not comprehend failed to change his rote approach. Like a fly stuck fast to flypaper, he was glued to the details of his immediate experience, and would not rise above these to find meaning in his dreary life, or even in his shameful death. Socrates was an original and constructive thinker who died rather than deny the purpose that he found in human life; Joseph K. was a leaden bureaucrat whose life was one long moment of guilty hesitation before a broader vision of things. Or is it that Socrates was an arrogant, peculiar, conniving failure who was engaged in an insidious attempt to undermine the moral and political values of Athens? And is it that Joseph K. was a successful young businessman who had established himself as a conscientious, decent, and eminently reasonable man struggling bravely for justice against an alien and capricious authority? Or perhaps these two trials should be seen as very similar. Each man was tried on charges of which he claimed to be innocent; each wanted to restore order and meaning to a disintegrating world; each led a life that became the cause of his death; and each was condemned for claiming that the unexamined life was not worth living. Or is it that Joseph K. was condemned for maintaining that it was the examined life that was not worth living...? 212 Cynthia B. Cohen213 Difficulties in the interpretation of works of literature are to be expected when their subjects are complex and subtle individuals set in an atmosphere in which basic questions of human significance are raised. Both the Apology and The Trial are such works. Socrates initially seems a model of clarity to the interpreter. He responds to his accusers in a form of direct discourse that can be taken at face value. He presents his arguments openly and cogently. There can be no doubt that his general position is coherent, consistent, and reasonable. Yet the interpreter 's initial satisfaction fades as Socrates' irony creates confusion about what Socrates professes to know. His lines of reasoning seem to intersect in paradox; his answers to questions about the meaning and purpose of human life curve around to miss each other. The interpreter emerges confused and perplexed. These transformations of perspective and significance are repeated in The Trial. Joseph K., too, is described in a straightforward manner that is clear and quite detailed. His reactions and arguments appear sensible and well-reasoned. Yet on closer examination, his simple statements turn out to have hidden meanings; his responses often contradict one another; his logical arguments appear pointless. His answers to questions about the meaning and purpose of human life are immediately challenged by a horde of competitors. To the interpreter, The Trial metamorphizes into a model of intentional obscurity. The problem of interpretation is compounded in the case of Socrates by the question of the accuracy of our information about him. The "Socratic problem" is well known. Each of the four major sources about his life and thought, Xenophon, Aristophanes, Plato, and Aristotle, presents a somewhat different person. There has been strong support for the view that the portrayal of Socrates in the earlier dialogues of Plato is essentially sound, even though this earlier Socrates seems at variance with the later one. The resolution of this problem is irrelevant to this endeavor. Our purpose is to consider the life and... (shrink)

Attentional focus is an area that has garnered considerable attention in the sport psychology and motor performance literature. This is unsurprising given that attentional focus has been directly linked to performance outcomes and is susceptible to coaching input. While research has amassed supporting benefits of an external focus of attention on motor performance using verbal instruction, other studies have challenged the notion that an EFA is more beneficial than an internal focus of attention for sport-related performance. Further, it is unclear (...) what type of instructions may serve to direct an athlete to an EFA and, in particular, if coaching can utilize imagery to orient an athlete toward an EFA. In the present exploratory study, we evaluate the effectiveness of instruction to improve free-throw shooting performance with an emphasis on an EFA brought about by implementing techniques borrowed from the imagery literature. This was tested relative to an alternate approach with an IFA induced through an emphasis on technique, devised to more closely resemble input typical of coach-to-athlete instruction. Twenty-five male and female university basketball players completed both conditions in a fully counterbalanced within-subject design. Results confirmed that participants in the EFA imagery condition had greater shooting accuracy than in the IFA technique condition.

The one central to personalized patient data that forms the core of traditional data warehousing solutions frequently faces problems of complexity and dissatisfaction. Deep learning with test automation solutions makes data ingestion, processing, and testing conversant through machine learning algorithms [1]. These systems encompass separate acts such as testing for data integration, testing (...) the quality of data as well as performance testing removing the factors of time and human error. In healthcare organizations, this approach delivers the message of enhancing quality, compliance and organizational efficiency in value-based care and precision medicine initiatives. As such, artificial intelligence tools can be used to address the essential issues regarding data warehousing, and this can in turn enhance decision-making, and thus, enhance the health of patient and the overall population.

Buildings energy consumption is growing gradually and put away around 40% of total energy use. Predicting heating and cooling loads of a building in the initial phase of the design to find out optimal solutions amongst different designs is very important, as ell as in the operating phase after the building has been finished for efficient energy. In this study, an artificial neural network model was designed and developed for predicting heating and cooling loads of a building based on (...) a dataset for building energy performance. The main factors for input variables are: relative compactness, roof area, overall height, surface area, glazing are a, wall area, glazing area distribution of a building, orientation, and the output variables: heating and cooling loads of the building. The dataset used for training are the data published in the literature for various 768 residential buildings. The model was trained and validated, most important factors affecting heating load and cooling load are identified, and the accuracy for the validation was 99.60%. (shrink)

Before going further, it will be helpful to consider briefly the notion that novelty per se is a fundamental human need. Experiments with human beings, as well as with animals, indicate that the maintenance of normal, successful behavior depends upon an adequate level of incoming stimulation—or, as some have put it, of novelty.2 But lumping all novelty together is misleading. At least three kinds of novelty need to be distinguished. Some novel patterns arise out of, or represent, changes in the (...) fundamental rules governing the organization of musical processes and structures. By significantly weakening our comprehension of the musical relationships presented—undermining not only our understanding of what is past but our ability to envisage what is to come—such systemic change seriously threatens our sense of psychic security and competent control. Far from being welcome, the insecurity and uncertainty thus engendered is at least as antipathetic, disturbing, and unpleasant as stimulus privation. Novel patterns may also result from the invention of a new strategy that accords with prevalent stylistic rules. Though they may initially seem to threaten existing competencies, the function and significance of novel strategies within the larger set of stylistic constraints can usually be grasped without too much delay or difficulty. For a while the tensions produced by strategic innovation may seem disturbing. But in the end, when our grasp of the principles ordering events is confirmed and our sense of competency is reestablished and control is reinforced, tension is resolved into an elation that is both stimulating and enjoyable. Most novel patterns—original themes, rhythms, harmonic progressions, and so forth—involve the innovative instantiation or realization of an existing strategy or schema .3 Novelties of this kind not only enhance our sense of control—a feeling that we know how things really “work”—but provide both the pleasure of recognition and the joy of skillfully exercising some competency. We enjoy novelty—the stimulation of surprise, the tension of uncertainty—as long as it can be accommodated within a known and understandable set of constraints. When the rules governing the game are abrogated or in doubt—when comprehension and control are threatened—the result is usually anger, anguish, and desperation.These responses to novelty are consequences of fundamental and poignant verities of the human condition: the centrality of choice in human behavior. Because only a minute fraction of human behavior seems to be genetically specified, choice is inescapable.While in lower organisms, behavior is strictly determined by the genetic program, in complex metazoa the genetic program becomes less constraining, more “open” as Ernst Mayr puts it, in the sense that it does not lay down behavioral instructions in great detail but rather permits some choice and allows for a certain freedom of response. Instead of imposing rigid prescriptions, it provides the organism with potentialities and capacities. This openness of the genetic program increases with evolution and culminates in mankind.4The price of freedom is the imperative of choice. Human beings must choose were to sow and when to reap, when to work and where to live, when to play and what to build. Intelligent, successful choices are possible only if alternative courses of action can be imagined and their consequences envisaged with reasonable accuracy. 2. For further discussion, see my Music, the Arts, and Ideas , p. 50.3. Rules are transpersonal but intracultural constraints—for instance, the pitch/time entities established in some style, as well as grammatical and syntactic regularities. Strategies are general means for actualizing some of the possibilities that are potential in the rules of the style. The rules of a style are relatively few, while the number of possible strategies may, depending upon the nature of the rules, be very large indeed. The ways of instantiating a particular strategy are, if not infinite, at least beyond reckoning.4. François Jacob, The Possible and the Actual , p. 61.

While often presented as promising assistive technologies for motor-impaired users, electroencephalography (EEG)-based Brain-Computer Interfaces (BCIs) remain barely used outside laboratories due to low reliability in real-life conditions. There is thus a need to design long-term reliable BCIs that can be used outside-of-the-lab by end-users, e.g., severely motor-impaired ones. Therefore, we propose and evaluate the design of a multi-class Mental Task (MT)-based BCI for longitudinal training (20 sessions over 3 months) of a tetraplegic user for the CYBATHLON BCI series 2019. In (...) this BCI championship, tetraplegic pilots are mentally driving a virtual car in a racing video game. We aimed at combining a progressive user MT-BCI training with a newly designed machine learning pipeline based on adaptive Riemannian classifiers shown to be promising for real-life applications. We followed a two step training process: the first 11 sessions served to train the user to control a 2-class MT-BCI by performing either two cognitive tasks (REST and MENTAL SUBTRACTION) or two motor-imagery tasks (LEFT-HAND and RIGHT-HAND). The second training step (9 remaining sessions) applied an adaptive, session-independent Riemannian classifier that combined all 4 MT classes used before. Moreover, as our Riemannian classifier was incrementally updated in an unsupervised way it would capture both within and between-session non-stationarity. Experimental evidences confirm the effectiveness of this approach. Namely, the classification accuracy improved by about 30% at the end of the training compared to initial sessions. We also studied the neural correlates of this performance improvement. Using a newly proposed BCI user learning metric, we could show our user learned to improve his BCI control by producing EEG signals matching increasingly more the BCI classifier training data distribution, rather than by improving his EEG class discrimination. However, the resulting improvement was effective only on synchronous (cue-based) BCI and it did not translate into improved CYBATHLON BCI game performances. For the sake of overcoming this in the future, we unveil possible reasons for these limited gaming performances and identify a number of promising future research directions. Importantly, we also report on the evolution of the user's neurophysiological patterns and user experience throughout the BCI training and competition. (shrink)

This transcription of notes made by Charles Darwin during the voyage of H. M. S. Beagle records his observations of the animals and plants that he encountered, and provides a valuable insight into the intellectual development of one of our most influential scientists. Darwin drew on many of these notes for his well known Journal of Researches (1839), but the majority of them have remained unpublished. This volume provides numerous examples of his unimpeachable accuracy in describing the wide range (...) of animals seen in the course of his travels, and of his closely analytical approach towards every one of his observations. Only at the very end of the voyage were his first doubts about the immutability of species expressed consciously, but here are to be found the initial seeds of his theory of evolution, and of the fields of behavioural and ecological study of which he was one of the founding fathers.

Corporate Social Responsibility reporting by large corporations has witnessed phenomenal growth over the last two decades. The voluntary nature of these disclosures, however, has led to inconsistencies in reporting formats, treatment, and inclusion of various contextual elements, and a lack of robust measures pertaining to the quality and accuracy of the reports’ content. Efforts to address these drawbacks such as Global Reporting Initiative and ISO 26000 have proven unsatisfactory due to their primary emphasis on process for creating CSR reports (...) without similar attention on measurement criteria to ensure robust implementation, or verify accuracy of information. This paper attempts to fill this gap in the literature. It uses a new framework—called the CSR-Sustainability Monitor®—of analyzing and evaluating the contents of CSR reports in a manner that allows for a single report to be compared with any other single group, and groups of reports based on industry, country-of-origin, and similar other groupings. Using data from the CSR reports of 614 large corporations worldwide, this study analyzes the character and scope of integrity assurance contained in these CSR reports. The analysis is further extended to explore some external factors that would explain variations in the assurance decision and the quality of integrity assurance in these reports. (shrink)

Individuals differ greatly in their ability to learn and navigate through environments. One potential source of this variation is “directional sense” or the ability to identify, maintain, and compare allocentric headings. Allocentric headings are facing directions that are fixed to the external environment, such as cardinal directions. Measures of the ability to identify and compare allocentric headings, using photographs of familiar environments, have shown significant individual and strategy differences; however, the neural basis of these differences is unclear. Forty-five college students, (...) who were highly familiar with a campus environment and ranged in self-reported sense-of-direction, underwent fMRI scans while they completed the Relative Heading task, in which they had to indicate the direction of a series of photographs of recognizable campus buildings (i.e., “target headings”) with respect to initial “orienting headings”. Large individual differences were found in accuracy and correct decision latencies, with gender, self-reported sense-of-direction, and familiarity with campus buildings all predicting task performance. Using linear mixed models, the directional relationships between headings and the experiment location also impacted performance. Structural scans revealed that lateral orbitofrontal and superior parietal volume were related to task accuracy and decision latency, respectively. Bilateral hippocampus and right presubiculum volume were related to self-reported sense-of-direction. Meanwhile, functional results revealed clusters within the superior parietal lobule, supramarginal gyrus, superior frontal gyrus, lateral orbitofrontal cortex, and caudate among others in which the intensity of activation matched the linear magnitude of the difference between the orienting and target headings. While the retrosplenial cortex and hippocampus have previously been implicated in the coding of allocentric headings, this work revealed that comparing those headings additionally involved frontal and parietal regions. These results provide insights into the neural bases of the variation within human orientation abilities, and ultimately, human navigation. (shrink)

The challenges with modeling the spread of Covid-19 are its power-type growth during the middle stages of the waves with the exponents depending on time, and that the saturation of the waves is mainly due to the protective measures and other restriction mechanisms working in the same direction. The two-phase solution we propose for modeling the total number of detected cases of Covid-19 describes the actual curves for many its waves and in many countries almost with the accuracy of (...) physics laws. Bessel functions play the key role in our approach. The differential equations we obtain are of universal type and can be used in behavioral psychology, invasion ecology (transient processes), etc. The initial transmission rate and the intensity of the restriction mechanisms are the key parameters. This theory provides a convincing explanation of the surprising uniformity of the Covid-19 waves in many places, and can be used for forecasting the epidemic spread. For instance, the early projections for the 3rd wave in the USA appeared sufficiently exact. The Delta-waves (2021) in India, South Africa, UK, and the Netherlands are discussed at the end. (shrink)

With the rapid development of the market economy, there are more and more projects in the financial industry, and their complexity and technical requirements are getting higher and higher. The development of computer technology has promoted the birth of robot consultants, and it is of great significance to use robot consultants to manage and supervise financial industry projects. In order to further analyze the development and supervision of robo-advisors under the digital inclusive financial system, this paper uses complex systems and (...) clustering algorithms as technical support to carry out research. First, the traditional K-means algorithm is used to select the initial clustering center, to improve the noise and outlier processing capabilities, and to build a data mining system based on the improved algorithm. Then, a product design model for robo-advisors is built and the risks of robo-advisors are analyzed from three aspects: technology, market, and law. Analyzing the performance of the improved K-means algorithm, in the operation of the experimental dataset B, the accuracy of the clustering result after 6 iterations reached 97.08%, which shows that the algorithm has good performance. During the trial operation of the data mining system, the four types of customers of financial institutions were accurately clustered, and it was concluded that the main type of customers who brought benefits to financial institutions was high-income customers accounting for 10.75%. Robo-advisory product models are used to build five risk-level investment portfolios and conduct risk backtests. Except for the growth and income portfolio, other portfolios have consistently outperformed the performance benchmark during the analyzed time period. Running the research system of this paper in a financial institution, comparing the capital budget before and after the operation, found that the system can improve the accuracy of the budget and reduce the risk of the robo-advisor for the financial institution.

Where Taber and Lodge view belief polarization to indicate a “partisan motivation,” Lord et al. (1979) believed it to be consistent with a desire for accuracy: A “weak” study articulating an opposing viewpoint might simply sharpen participants' initial belief of the wisdom of their prior beliefs. This polarization, Taber and Lodge show, correlates with political sophistication: The more partisan a participant, the more time spent reading the opinions of the other side—in order to critically refute them. Taber and (...) Lodge attribute such findings to people's personal identification with their beliefs. However, participants may have spent so much time reading opinions of the other side because the arguments are unfamiliar. Further, Lord et al. (1984) were able to induce people to act with “skepticism” toward their own views by simply suggesting that they “consider the other side.”. (shrink)

The current research investigates how prior preferences affect causal learning. Participants were tasked with repeatedly choosing policies (e.g., increase vs. decrease border security funding) in order to maximize the economic output of an imaginary country and inferred the influence of the policies on the economy. The task was challenging and ambiguous, allowing participants to interpret the relations between the policies and the economy in multiple ways. In three studies, we found evidence of motivated reasoning despite financial incentives for accuracy. (...) For example, participants who believed that border security funding should be increased were more likely to conclude that increasing border security funding actually caused a better economy in the task. In Study 2, we hypothesized that having neutral preferences (e.g., preferring neither increased nor decreased spending on border security) would lead to more accurate assessments overall, compared to having a strong initial preference; however, we did not find evidence for such an effect. In Study 3, we tested whether providing participants with possible functional forms of the policies (e.g., the policy takes some time to work or initially has a negative influence but eventually a positive influence) would lead to a smaller influence of motivated reasoning but found little evidence for this effect. This research advances the field of causal learning by studying the role of prior preferences, and in doing so, integrates the fields of causal learning and motivated reasoning using a novel explore‐exploit task.

In the model proposed by Findlay & Walker, the programming of saccadic eye movements is achieved by two parallel processes, one dedicated to the coding of saccade metrics (Where) and the other controlling saccade initiation (When). One outcome of the “winner-take-all” characteristics of the salience map, the main node of the model, is an independence between the metrics and the latency of saccades. We report on some observations, made in the head-unrestrained cat under pathological conditions, of a correlation between (...) class='Hi'>accuracy and latency of saccadic gaze shifts. To account for such a correlation, the link between metrics specification (Where) and saccade triggering (When) should be amended in the model. (shrink)

In this study I attempt to provide an answer to the question how the Babylonian scholars arrived at their mathematical theory of planetary motion. Although no texts are preserved in which the Babylonians tell us how they did it, from the surviving Astronomical Diaries we have a fairly complete picture of the nature of the observational material on which the scholars must have based their theory and from which they must have derived the values of the defining parameters. Limiting the (...) discussion to system A theory of the outer planets Saturn, Jupiter and Mars, I will argue that the development of Babylonian planetary theory was a gradual process of more than a century, starting sometime in the fifth century BC and finally resulting in the appearance of the first full-fledged astronomical ephemeris around 300 BC. The process of theory formation involved the derivation of long “exact” periods by linear combination of “Goal–Year” periods, the invention of a 360° zodiac, the discovery of the variable motion of the planets and the development of the numerical method to model this as a step function. Longitudes of the planets in the Babylonian zodiac could be determined by the scholars with an accuracy of 1° to 2° from observations of angular distances to Normal Stars with known positions. However, since the sky is too bright at first and last appearances of the planets and at acronychal rising for nearby stars to be visible, accurate longitudes as input for theoretical work could only be determined when the planets were near the stationary points in their orbits. In this study I show that the Babylonian scholars indeed based their system A modeling of the outer planets on planetary longitudes near stations, that their system A models of Saturn and Jupiter provided satisfactory results for all synodic phenomena, that they realized that their system A model of Mars did not produce satisfactory results for the second station so that separate numerical schemes were constructed to predict the positions of Mars at second station from the model at first station, and finally that their system A model for Mars provided quite poor predictions of the longitude of Mars at first and last appearances over large stretches of the zodiac. I further discuss ways in which the parameters of the system A models may have been derived from observations of the outer planets. By analyzing contemporaneous ephemerides from Uruk of four synodic phenomena of Jupiter from the second century BC, I finally illustrate how the Babylonian scholars may have used observations of Normal Star passages of planets to choose the initial conditions for their ephemerides.

In criminal trials, evidence often involves a degree of uncertainty and decision-making includes moving from the initial presumption of innocence to inference about guilt based on that evidence. The jurors’ ability to combine evidence and make accurate intuitive probabilistic judgments underpins this process. Previous research has shown that errors in probabilistic reasoning can be explained by a misalignment of the evidence presented with the intuitive causal models that people construct. This has been explored in abstract and context-free situations. However, (...) less is known about how people interpret evidence in context-rich situations such as legal cases. The present study examined participants’ intuitive probabilistic reasoning in legal contexts and assessed how people’s causal models underlie the process of belief updating in the light of new evidence. The study assessed whether participants update beliefs in line with Bayesian norms and if errors in belief updating can be explained by the causal structures underpinning the evidence integration process. The study was based on a recent case in England where a couple was accused of intentionally harming their baby but was eventually exonerated because the child’s symptoms were found to be caused by a rare blood disorder. Participants were presented with a range of evidence, one piece at a time, including physical evidence and reports from experts. Participants made probability judgments about the abuse and disorder as causes of the child’s symptoms. Subjective probability judgments were compared against Bayesian norms. The causal models constructed by participants were also elicited. Results showed that overall participants revised their beliefs appropriately in the right direction based on evidence. However, this revision was done without exact Bayesian computation and errors were observed in estimating the weight of evidence. Errors in probabilistic judgments were partly accounted for, by differences in the causal models representing the evidence. Our findings suggest that understanding causal models that guide people’s judgments may help shed light on errors made in evidence integration and potentially identify ways to address accuracy in judgment.

In lieu of an abstract, here is a brief excerpt of the content:Who or What is the Preembryo?S.J. Richard A. McCormick (bio)IntroductionAlthough widely used by scientists, the term "preembryo" has raised some suspicions. Histopathologist Michael Jarmulowicz (1990), for example, asserts that the term was adopted by the American Fertility Society (AFS) and the Voluntary Licensing Authority (VLA) in Britain "as an exercise of linguistic engineering to make human embryo research more palatable to the general public."I cannot speak for the VLA, (...) but I can clarify that this was not the motive of the AFS. As a member of the AFS ethics committee that discussed and adopted this terminology, I know that our discussion was not tied to embryo research or moral issues. The term "preembryo" was adopted because the earliest stages of mammalian development primarily involve establishment of the nonembryonic trophoblast, rather than the formation of the embryo. As Clifford Grobstein (1988, p. 61), a distinguished basic scientist who also sat on the AFS committee notes:The scientific rationale for the term preembryo... is its greater accuracy in characterizing the initial phase of mammalian and human development.... The status implications of such a change in terminology were not at issue in the discussion.This is not to say that the moral status of the preembryo is not a concern worthy of independent consideration. It is an important question with significant practical implications, especially in the context of in vitro fertilization. At stake are issues such as: (1) what may be done to preembryos before transfer; (2) whether all preembryos must be transferred; and (3) what may be done to preembryos that are not transferred (Ethics Committee of the American Fertility Society (AFS) 1986, p. 29S). Furthermore, emergency treatment of rape cases may also depend on such a determination. [End Page 1]Cryopreservation, which entails freezing unused preembryos for possible later use, is one example of a procedure that raises issues associated with the moral status of the preembryo. Cryopreservation decreases the number of stimulated egg recovery cycles a woman must undergo and increases flexibility in transfer protocols. But thawing of the preembryos is not a completely benign process; significant numbers of the preembryos die in the process and injury cannot be excluded.In addition, down the road a year or so lies preimplantation genetic diagnosis, now being tested in several centers of reproductive research. This would involve the removal of one or more cells from a preembryo developing in vitro. The DNA from these cells would be studied and then only genetically normal preembryos would be transferred. With the growth in knowledge about single gene defects and the rapid advance of amplification technology, which allows gene visualization, it is not difficult to imagine scientists embarking on a variety of micromanipulations of the preembryo for the sake of gaining knowledge.Not all research with gametes involves preembryos, but clearly some experiments and procedures await resolution of the moral status of the preembryo. I contend in this paper that the moral status—and specifically the controversial issue of personhood—is related to attainment of developmental individuality (being the source of one individual). This contrasts with the view that holds that personhood occurs earlier, at the point of genetic uniqueness. I believe that an embryo that has developed to the point where it can be one individual and one individual only, differs in moral status from a preembryo that has not, even if in many cases we may choose to treat them similarly.The Scientific UnderpinningsTwo things must be kept in mind—and in a sense, in tension—in turning to science for help in assessing the status of the preembryo. First, science is not competent to decide the question of personhood or ensoulment. As the Catholic document, Declaration on Procured Abortion, which I will return to later, notes: "It is a philosophical problem" (Congregation for the Doctrine of the Faith (CDF) 1974, p. 10, endnote 19). On the other hand, another Catholic document, Donum vitae(CDF 1987), notes that the conclusions of science provide a "valuable indication" for reason's deliberations about personhood. We might say that if science cannot decide the question of personhood, neither can it be decided without science.For my review of embryological science... (shrink)

Evapotranspiration represents the water requirement of plants during their growing season, and its accurate measurement at the farm is essential for agricultural water planners and managers. Field measurements of evapotranspiration have always been associated with many difficulties that have led researchers to seek a way to remotely measure this component in horticultural and agricultural areas. This study aims to investigate an indirect approach for daily rice crop evapotranspiration measurement by machine learning techniques and the least available climatic variables. For this (...) purpose, daily meteorological variables were obtained from three ground meteorological stations in rice cultivation regions of northern Iran during 2003–2016. The ETc rates were calculated by seven meteorological variables, the FAO-56 Penman-Monteith equation, and the regional calibrated rice crop coefficient and considered as the reference data. The MLs, including Multilayer Perceptron, Radial Basis Function, Generalized Regression Neural Network, and Group Method of Data Handling, were utilized for ETc modeling. Different input combinations were applied, based on the use of minimum effective variables as input. Results showed that the models showed the most accurate performances in the input combination of four climatic variables: sunshine duration, maximum temperature, relative humidity, and wind speed. Investigating the accuracy of models in rice growth phases showed that the least estimation error belonged to the initial growing stage, which increased during the mid-season and late-season growing stages. A comparison of the models showed that the GMDH model performed better against the other competitors. For this model, both the Nash-Sutcliffe coefficient and R2 were greater than 0.98, and the Root Mean Square Error ranged between 0.214 and 0.234 mm per day in all stations. The current approach showed promising results in rice evapotranspiration modeling by only four common meteorological variables and can be reliably applied for indirect measurement of this variable over the rice farms. The studied approach will have research value for rice and other crops in similar/different climatic conditions. (shrink)

This study suggests a new approach to EEG data classification by exploring the idea of using evolutionary computation to both select useful discriminative EEG features and optimise the topology of Artificial Neural Networks. An evolutionary algorithm is applied to select the most informative features from an initial set of 2550 EEG statistical features. Optimisation of a Multilayer Perceptron is performed with an evolutionary approach before classification to estimate the best hyperparameters of the network. Deep learning and tuning with Long (...) Short-Term Memory are also explored, and Adaptive Boosting of the two types of models is tested for each problem. Three experiments are provided for comparison using different classifiers: one for attention state classification, one for emotional sentiment classification, and a third experiment in which the goal is to guess the number a subject is thinking of. The obtained results show that an Adaptive Boosted LSTM can achieve an accuracy of 84.44%, 97.06%, and 9.94% on the attentional, emotional, and number datasets, respectively. An evolutionary-optimised MLP achieves results close to the Adaptive Boosted LSTM for the two first experiments and significantly higher for the number-guessing experiment with an Adaptive Boosted DEvo MLP reaching 31.35%, while being significantly quicker to train and classify. In particular, the accuracy of the nonboosted DEvo MLP was of 79.81%, 96.11%, and 27.07% in the same benchmarks. Two datasets for the experiments were gathered using a Muse EEG headband with four electrodes corresponding to TP9, AF7, AF8, and TP10 locations of the international EEG placement standard. The EEG MindBigData digits dataset was gathered from the TP9, FP1, FP2, and TP10 locations. (shrink)
