Introduction of deep neural networks to the machine translation research ameliorated conventional machine translation systems in multiple ways, specifically in terms of translation quality. The ability of deep neural networks to learn a sensible representation of words is one of the major reasons for this improvement. Despite machine translation using deep neural architecture is showing state-of-the-art results in translating European languages, we cannot directly apply these algorithms in Indian languages mainly because of two reasons: unavailability of the good corpus and (...) Indian languages are morphologically rich. In this paper, we propose a neural machine translation (NMT) system for four language pairs: English–Malayalam, English–Hindi, English–Tamil, and English–Punjabi. We also collected sentences from different sources and cleaned them to make four parallel corpora for each of the language pairs, and then used them to model the translation system. The encoder network in the NMT architecture was designed with long short-term memory (LSTM) networks and bi-directional recurrent neural networks (Bi-RNN). Evaluation of the obtained models was performed both automatically and manually. For automatic evaluation, the bilingual evaluation understudy (BLEU) score was used, and for manual evaluation, three metrics such as adequacy, fluency, and overall ranking were used. Analysis of the results showed the presence of lengthy sentences in English–Malayalam, and the English–Hindi corpus affected the translation. Attention mechanism was employed with a view to addressing the problem of translating lengthy sentences (sentences contain more than 50 words), and the system was able to perceive long-term contexts in the sentences.

Traditionally spatial transformations such as translations and rotations are formulated in terms of transformations of the entire spatial space. In other words, transformations are taken automatically to be of a global nature. This paper investigates a local approach to spatial transformations; local transformations lead naturally to local observables in quantum mechanics.

Using the Stroop paradigm, we have previously shown that a specific suggestion can remove or reduce involuntary conflict and alter information processing in highly suggestible individuals . In the present study, we carefully matched less suggestible individuals to HSIs on a number of factors. We hypothesized that suggestion would influence HSIs more than LSIs and reduce the Stroop effect in the former group. As well, we conducted secondary post hoc analyses to examine negative priming – the apparent disruption of the (...) response to a previously-ignored item. Our present findings indicate that suggestion reduces Stroop effects in HSIs. Secondary analyses show that LSIs had an NP effect at baseline and that suggestion influenced the NP condition. Thus, at least in this experimental context, suggestion seems to dampen a deeply-engrained and largely automatic process – reading – by wielding a larger influence on HSIs relative to comparable LSIs.

Cognitive scientists routinely distinguish between controlled and automatic mental processes. Through learning, practice, and exposure, controlled processes can become automatic; however, whether automatic processes can become deautomatized – recuperated under the purview of control – remains unclear. Here we show that a suggestion derails a deeply ingrained process involving involuntary audiovisual integration. We compared the performance of highly versus less hypnotically suggestible individuals in a classic McGurk paradigm – a perceptual illusion task demonstrating the influence of visual (...) facial movements on auditory speech percepts. Following a posthypnotic suggestion to prioritize auditory input, HSIs but not LSIs manifested fewer illusory auditory perceptions and correctly identified more auditory percepts. Our findings demonstrate that a suggestion deautomatized a ballistic audiovisual process in HSIs. In addition to guiding our knowledge regarding theories and mechanisms of automaticity, the present findings pave the road to a more scientific understanding of top-down effects and multisensory integration.

Social relationships are constructed by and through the relational communication that people exchange. Relational messages are implicit nonverbal and verbal messages that signal how people regard one another and define their interpersonal relationships—equal or unequal, affectionate or hostile, inclusive or exclusive, similar or dissimilar, and so forth. Such signals can be measured automatically by the latest machine learning software tools and combined into meaningful factors that represent the socioemotional expressions that constitute relational messages between people. Relational messages operate continuously on (...) a parallel track with verbal communication, implicitly telling interactants the current state of their relationship and how to interpret the verbal messages being exchanged. We report an investigation that explored how group members signal these implicit messages through multimodal behaviors measured by sensor data and linked to the socioemotional cognitions interpreted as relational messages. By use of a modified Brunswikian lens model, we predicted perceived relational messages of dominance, affection, involvement, composure, similarity and trust from automatically measured kinesic, vocalic and linguistic indicators. The relational messages in turn predicted the veracity of group members. The Brunswikian Lens Model offers a way to connect objective behaviors exhibited by social actors to the emotions and cognitions being perceived by other interactants and linking those perceptions to social outcomes. This method can be used to ascertain what behaviors and/or perceptions are associated with judgments of an actor’s veracity. Computerized measurements of behaviors and perceptions can replace manual measurements, significantly expediting analysis and drilling down to micro-level measurement in a previously unavailable manner.

We show how to reconstruct the topology on the monoid of endomorphisms of the rational numbers under the strict or reflexive order relation, and the polymorphism clone of the rational numbers under the reflexive relation. In addition we show how automatic homeomorphicity results can be lifted to polymorphism clones generated by monoids.

Computation of seismic parameters and its interpretation from the recorded earthquake signal is empowered by digital data acquisition systems. This enables seismologist to automatically compute all the relevant parameters. Futuristic applications require extensive software development to implement seismic prediction and forecasting models. While developing such models, software developer prefer to write their own in-house analysis & modeling software with complete control over the required computations and models. This paper presents simplified mathematical framework of the seismic events and back-end computational software (...) logic & algorithm to provide a simple framework to software engineers develop customized seismic analysis & computation software.

In recent years, many studies have shown that perceiving other individuals’ direct gaze has robust effects on various attentional and cognitive processes. However, considerably less attention has been devoted to investigating the affective effects triggered by eye contact. This article reviews research concerning the effects of others’ gaze direction on observers’ affective responses. The review focuses on studies in which affective reactions have been investigated in well-controlled laboratory experiments, and in which contextual factors possibly influencing perceivers’ affects have been controlled. (...) Two important themes emerged from this review. First, explicit affective evaluations of seeing another’s direct versus averted gaze have resulted in rather inconsistent findings; some studies report more positive subjective feelings to direct compared to averted gaze, whereas others report the opposite pattern. These contradictory findings may be related, for example, to differences between studies in terms of the capability of direct-gaze stimuli to elicit feelings of self-involvement. Second, studies relying on various implicit measures have reported more consistent results; they indicate that direct gaze increases affective arousal, and more importantly, that eye contact automatically evokes a positively valenced affective reaction. Based on the review, possible psychological mechanisms for the positive affective reactions elicited by eye contact are described. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Journal of Aesthetic Education 37.2 (2003) 73-79 [Access article in PDF] Does Film Weaken Spectator Consciousness? R.D. Boyd and S.K. Wertz The role of spectator is crucial for an actor, for there are "no actors without spectators." 1 At times the success of the actor depends upon the role taken by the spectator. Thornton Wilder's "Our Town" depends upon an active,creative, involved audience. Other artists expect their audience (...) to be passive,almost unconscious. Whether the medium of creativity is film or the printedpage, examples of both dependencies abound. The focus of this essay is ona classic piece in the literature about film. In the Theory of Film, Siegfried Kracauer provides us with a mesmerizing printed discussion of film. 2 In this essay we wish to examine his reasoning that is in a self-contained argument by analogy. Since Kracauer does not use or mention the argument thereafter, we feel that we can isolate the argument from its context and deal with it as it stands. After an extended analysis of the argument, we will relate some of the points to the literature on film. The following analogical argument is our focus. Films...tend to weaken the spectator's consciousness. Its withdrawal from the scene may be furthered by the darkness in moviehouses. Darkness automatically reduces our contacts with actuality, depriving us of many environmental data needed for adequate judgments and other mental activities. It lulls the mind....Devotees of film and its opponents alike have compared the medium to a sort of drug and have drawn attention to its stupefying effects....Doping creates dope addicts. It would seem a sound proposition that the cinema has its habitues who frequent it out of an all but physiological urge. They are not prompted by a desire to look at a specific film or to be pleasantly entertained; what they really crave is for once to be released from the grip of consciousness, lose their identity in the dark, and let sink in, [End Page 73] with their senses ready to absorb them, the images as they happen to follow each other on the screen. 3To support his main point, "Films...tend to weaken the spectator's consciousness," Kracauer develops three intermediate arguments (IA's), which support his major argument (MA). If each sentence in the above passage were numbered one through nine, with the last full sentence being broken into two sentences at the semicolon, the following schema emerges. In English the chain of reasoning is: IA-1 Some habitues of film are not prompted by a desire to look at a specific film or to be pleasantly entertained. What they really crave is release fromthe grip of consciousness, to lose their identity in the dark, and let sink in, with their senses ready to absorb them, the images as they happen to follow each other on the screen. Therefore, the cinema has its habitues who frequent it out of an all but physiological urge.IA-2 Some habitues of film frequent it out of an all but physiological urge. Doping creates dope addicts. Therefore, devotees of film and its opponents alike have compared the medium to a sort of drug and have drawn attention to its stupefying effects.IA-3 Darkness automatically reduces our contacts with actuality, depriving us of many environmental data needed for adequate judgments and other mental activities. Darkness lulls the mind. Therefore, consciousness withdrawal from the scene may be furthered by the darkness in moviehouses.MA Devotees of film and its opponents alike have compared the medium to a sort of drug and have drawn attention to its stupefying effects. Consciousness withdrawal from the scene may be furthered by the darkness in moviehouses. Therefore, films...tend to weaken the spectator's consciousness. The above chain of arguments influences us, the spectators, to embrace his main point. However, before we are lulled into accepting his reasoning, it will be helpful to examine and evaluate each link. [End Page 74]IA-1 Some habitues of film are not prompted by a desire to... (shrink)

This paper implements the continuous Hindi Automatic Speech Recognition (ASR) system using the proposed integrated features vector with Recurrent Neural Network (RNN) based Language Modeling (LM). The proposed system also implements the speaker adaptation using Maximum-Likelihood Linear Regression (MLLR) and Constrained Maximum likelihood Linear Regression (C-MLLR). This system is discriminatively trained by Maximum Mutual Information (MMI) and Minimum Phone Error (MPE) techniques with 256 Gaussian mixture per Hidden Markov Model(HMM) state. The training of the baseline system has been done (...) using a phonetically rich Hindi dataset. The results show that discriminative training enhances the baseline system performance by up to 3%. Further improvement of ~7% has been recorded by applying RNN LM. The proposed Hindi ASR system shows significant performance improvement over other current state-of-the-art techniques. (shrink)

Pure representationalism or intentionalism for phenomenal experience is the theory that all introspectible qualitative aspects of a conscious experience can be analyzed as qualities that the experience non-conceptually represents the world to have. Some philosophers have argued that experiences such as afterimages, phosphenes and double vision are counterexamples to the representationalist theory, claiming that they are non- representational states or have non-representational aspects, and they are better explained in a qualia-theoretical framework. I argue that these states are fully representational states (...) of a certain kind, which I call “automatically non-endorsed representations”, experiential states the veridicality of which we are almost never committed to, and which do not trigger explicit belief or disbelief in the mind of the subject. By investigating descriptive accounts of afterimages by two qualia theorists, I speculate that the mistaken claims of some anti-representationalists might be rooted in confusing two senses of the term “seeming”.

Since our moral and legal judgments are focused on our decisions and actions, one would expect information about the neural underpinnings of human decision-making and action-production to have a significant bearing on those judgments. However, despite the wealth of empirical data, and the public attention it has attracted in the past few decades, the results of neuroscientific research have had relatively little influence on legal practice. It is here argued that this is due, at least partly, to the discussion on (...) the relationship of the neurosciences and law mixing up a number of separate issues that have different relevance on our moral and legal judgments. The approach here is hierarchical; more and less feasible ways in which neuroscientific data could inform such judgments are separated from each other. The neurosciences and other physical views on human behavior and decision-making do have the potential to have an impact on our legal reasoning. However, this happens in various different ways, and too often appeal to any neural data is assumed to be automatically relevant to shaping our moral and legal judgments. Our physicalist intuitions easily favor neural-level explanations to mental-level ones. But even if you were to subscribe to some reductionist variant of physicalism, it would not follow that all neural data should be automatically relevant to our moral and legal reasoning. However, the neurosciences can give us indirect evidence for reductive physicalism, which can then lead us to challenge the very idea of free will. Such a development can, ultimately, also have repercussions on law and legal practice. (shrink)

We asked whether the influence of an invisible prime on movement is dependent on conscious movement expectations. Participants reached to a central target, which triggered a directional prime–mask arrow sequence. Participants were instructed that the visible arrows would most often signal a movement modification in a specific direction. Kinematic analyses revealed that responses to the visible mask were influenced by participants’ intentional bias, as movements were fastest when the more probable mask was displayed. In addition, responses were influenced by the (...) invisible prime without regard to its relationship to the more probable mask. Analysis of the time of initial trajectory modifications revealed that both primes influenced responses in a similar manner after accounting for participants’ bias. These results imply that invisible stimuli automatically activate their associated responses and that unconscious priming of the motor system is insensitive to the conscious expectations of the participant making the pointing movements.

In lieu of an abstract, here is a brief excerpt of the content:Josiah Royce on RaceIssues in ContextJacquelyn Ann K. KegleyAll philosophy, whether or not we want to admit it, is done in a context, filtered through lenses that are personal, intellectual, historical, cultural, social, and political. Thus to fairly treat and fully understand Royce's views on race, we must set a situational framework. First, Royce's 1906 article entitled "Race Questions and Prejudices" is the lead piece in a collection that (...) implements his philosophy of loyalty. It applies his principle of loyalty to what he considers one of the most significant social/political issues of his time—the race question. As we discuss Royce and race issues, the philosophy of loyalty must be in the background as a point of reference. Indeed, Royce tells us that he will address the various questions in his article "Race Questions and Prejudices" by calling attention to "a few principles which seem to me to be serviceable to any one who wants to look at race questions fairly and humanely" (6).Secondly, except for W. E. B. DuBois and Jane Addams, no other major figure associated with pragmatic philosophy substantially addressed issues of race and racism in their written work, nor did anyone so early in the twentieth century as did Royce. DuBois's The Souls of Black Folk, which came out in 1903, immediately preceded Royce's article. Jane Addams briefly touched on race issues in her 1915 Democracy and Social Ethics. Alain Locke, who sought to study with Royce at Harvard but could not because of Royce's premature death, gave his "Lectures on the Theory and Practice of Race" in 1915, but they were published posthumously. John Dewey's "Race Prejudice and Friction" appeared in 1922. There is an absence of treatment of race issues in George Herbert Mead, Charles Sanders Peirce, and Alfred North Whitehead. Thus Shannon Sullivan and I agree that Royce stands out in the history of classical American philosophy in taking an antiracist focus on race questions when very few philosophers—especially white male philosophers—took scholarly time to think about these issues.1 [End Page 1]Another important context for Royce's article is the political climate of the time. Royce identifies the era as one in which there were "more ways and places in which men find themselves in the presence of alien races with whom they have to live in the same social order" (4). It was a time of "white anxiety." In 1905, Theodore Roosevelt gave his famous "On American Motherhood" speech in which he warned of white "race suicide" if white families continued to reproduce at a slower rate than other races. Thus, Royce was speaking and writing against racism in a time of anti-immigration and proimperialism sentiment due to white anxiety in the United States about the possible decline of global white supremacy. It is in this setting that Royce highlights the color line as a significant problem.Royce states the problem as follows:This is the problem of dealing with the men who seem to us somehow very widely different from ourselves in physical constitution, in temperament, in all their deeper nature, so that we are temped to think of them as natural strangers to our souls, while nevertheless we find that they are stubbornly there in our world and that they are men as much determined to live as we are, and are men who, in turn, find us as incomprehensible as we find them.(5)With increased contact among different populations, the age-old problem of how to deal with people who seem different from one's own group intensifies. There will be, says Royce, numerous questions including those of superiority-inferiority, power and sovereignty, and a new assessment of the ways in which these "different" people might be helpful or perilous to one's own group interests. Royce notes that one cannot assume an automatic answer. He asks, "Is it a ‘yellow peril,' or a ‘black peril,' or perhaps after all, is it not rather some form of ‘white peril' which threatens the future of humanity in this day of great struggles and of complex issues?" (6). With the question posed in this... (shrink)

In the case of magnetic resonance imaging (MRI) imaging, image processing is crucial. In the medical industry, MRI images are commonly used to analyze and diagnose tumor growth in the body. A number of successful brain tumor identification and classification procedures have been developed by various experts. Existing approaches face a number of obstacles, including detection time, accuracy, and tumor size. Early detection of brain tumors improves options for treatment and patient survival rates. Manually segmenting brain tumors from a significant (...) number of MRI data for brain tumor diagnosis is a tough and time-consuming task. Automatic image segmentation of brain tumors is required. The objective of this study is to evaluate the degree of accuracy and simplify the medical picture segmentation procedure used to identify the type of brain tumor from MRI results. Additionally, this work suggests a novel method for identifying brain malignancies utilizing the Bagging Ensemble with K-Nearest Neighbor (BKNN) in order to raise the KNN’s accuracy and quality rate. For image segmentation, a U-Net architecture is utilized first, followed by a bagging-based k-NN prediction algorithm for classification. The goal of employing U-Net is to improve the accuracy and uniformity of parameter distribution in the layers. Each decision tree is fitted on a little different training dataset during classification, and the bagged decision trees are effective since each tree has minor differences and generates slightly different skilled predictions. The overall classification accuracy was up to 97.7 percent, confirming the efficiency of the suggested strategy for distinguishing normal and pathological tissues from brain MR images; this is greater than the methods that are already in use.

Research suggests that the reaching hand automatically deviates toward a target that changes location during the reach. In the current study, we investigated whether movement intention can influence the target jump’s impact on the hand. We compared the degree of trajectory deviation to a jumped target under three instruction conditions: GO, in which participants were told to go to the target if it jumped, STOP, in which participants were told to immediately stop their movement if the target jumped, and IGNORE, (...) in which participants were told to ignore the target if it jumped and to continue to its initial location. We observed a reduced response to the jump in the IGNORE condition relative to the other conditions, suggesting that the response to the jump is contingent on the jump being a task-relevant event.

Capitalizing on the constructivist approach developed by philosophers and psychologists, Steven Katz argues that mystical experience is in part constructed, shaped and colored by the concepts and beliefs which the mystic brings to it. Merits and problems of this constructivist account of mysticism are discussed. The approach is seen to be ill-suited to explain the novelties and surprises for which mysticism is renowned. A new model is suggested: that mysticism is produced by a process similar to forgetting. Two forms of (...) forgetting are described: a massive and complete forgetting of concepts in the “pure consciousness event” and de automatization in the more permanent unitive experiences. (shrink)

The increasing complexity of biological problems and the increase of mathematical means to handle them on the one hand, and the possibility of automatized computation at the other, necessitate a revaluation of the present interactions between biology and mathematics; in this connection interrelations occur which can be divided into three kinds: mathematical biology, biological mathematics, and general biomathematics or methodology of the biomathematical sciences, by which are meant those scientific branches which arise from the said interactions.

ABSTRACTThe recognition of emotional facial expressions is often subject to contextual influence, particularly when the face and the context convey similar emotions. We investigated whether spontaneous, incidental affective theory of mind inferences made while reading vignettes describing social situations would produce context effects on the identification of same-valenced emotions as well as differently-valenced emotions conveyed by subsequently presented faces. Crucially, we found an effect of context on reaction times in both experiments while, in line with previous work, we found evidence (...) for a context effect on accuracy only in Experiment 1. This demonstrates that affective theory of mind inferences made at the pragmatic level of a text can automatically, contextually influence the perceptual processing of emotional facial expressions in a separate task even when those emotions are of a distinctive valence. Thus, our novel findings suggest that language acts as a contex... (shrink)

Certain emotional processes “bypass the will” and even awareness, whereas others arise due to the deliberative evaluation of objects, states, and events. It is important to differentiate between the automatic versus reflective origins of emotional processes, and sensory versus conceptual bases of diverse negative and positive emotions. A taxonomy of emotions based on different origins is presented. This taxonomy distinguishes between negative and positive automatic versus reflective emotions. The automatic emotions are connected with the (a) homeostatic and (...) (b) hedonistic regulatory mechanisms. The reflective emotions—uniquely human—are described in reference to deliberative processes and appraisals based on two types of conceptual and verbalized evaluative standards: (a) ideal self-standards and (b) general, axiological standards of good and evil.

Substantive scientific letter writing is a cost-effective mode of complementing observational and experimental research. The value of such philosophically uncommitted and unsponsored well-balanced scientific activity has been relegated. Critical letter writing entails the abilities to: maintain rational scepticism; refuse to conform in order to explain data; persist in keeping common sense centre-stage; exercise logic to evaluate the biological significance of mathematical figures, including statistics, and the ability to sustain the will to share insights regarding disease mechanisms on an ostensibly lower (...) research platform. During peer review, innovative letter writing may share the occasionally unfortunate fate of innovative research. Rejected scientific letters do not automatically lose copyright. Periodicals with high letter loads will see some valuable contributions wasted, but that is the price for maintaining autonomy in scientific publication. The scientific community is an integrated whole that must respect the rights of authors at all levels. Unauthorised forwarding of rejected letters sets the dangerous precedent of justifying unjust means. (shrink)

The article presents two studies based on the assumption that the effectiveness of cognitive control depends on the subject’s type of emotional state. Inhibitory control is taken into account, as the basic determinant of the antisaccade reactions and the emotional Stroop effect. The studies deal with differentiation of emotions on the basis of their origin: automatic vs. reflective. According to the main assumption, automatic emotions are diffusive, and decrease the effectiveness of cognitive control. The hypothesis predicted that performance (...) level of both the Antisaccade Task and the Emotional Stroop Test would be lower in the automaticemotion eliciting condition than in the reflective-emotion eliciting condition. In two experimental studies, positive and negative emotions were elicited. The results support the predictions, regardless of the valence of emotions. (shrink)

Gundel, Hedberg and Zacharski propose a framework whereby different referring forms conventionally signal different cognitive statuses on an implica-tional 'givenness hierarchy'. Interaction of the hierarchy with Grice's Maxim of Quantity gives rise to scalar implicatures which further constrain the choice among forms and their interpretations when necessary conditions for more than one form are met. Wilson and Matsui show that reference assignment for NPs introduced by the definite article is constrained within Relevance Theory by the automatic selection of an (...) interpretation that yields adequate contextual effects for minimal processing effort. This paper proposes that an optimal account of how people understand the intended referent of an NP must appeal to both the Givenness Hierarchy and Relevance Theory. Such an account still requires the first part of the Quantity Maxim, however, either as a socially based assumption or as part of the Principle of Relevance itself. (shrink)

Recent studies have provided evidence of associations between neurochemistry and reading (dis)ability (Pugh et al., 2014). Based on a long history of studies indicating that fluent reading entails the automatic convergence of the written and spoken forms of language and our recently proposed Neural Noise Hypothesis (Hancock et al., 2017), we hypothesized that individual differences in cross-modal integration would mediate, at least partially, the relationship between neurochemical concentrations and reading. Cross-modal integration was measured in 231 children using a two-alternative (...) forced choice cross-modal matching task with three language conditions (letters, words, and pseudowords) and two levels of difficulty within each language condition. Neurometabolite concentrations of Choline (Cho), Glutamate (Glu), gamma-Aminobutyric (GABA), and N- acetyl-aspartate (NAA) were then measured in a subset of this sample (n = 70) with Magnetic Resonance Spectroscopy (MRS). A structural equation mediation model revealed that the effect of cross-modal word matching mediated the relationship between increased Glu (which has been proposed to be an index of neural noise) and poorer reading ability. In addition, the effect of cross-modal word matching fully mediated a relationship between increased Cho and poorer reading ability. Multilevel mixed effects models confirmed that lower Cho predicted faster cross-modal matching reaction time, specifically in the hard word condition. These Cho... (shrink)

In this paper, we will consider the neuro-cognitive systems involved in mediating morality. Five main claims will be made. First, that there are multiple, partially separable neuro-cognitive architectures that mediate specific aspects of morality: social convention, care-based morality, disgust-based morality and fairness/justice. Second, that all aspects of morality, including social convention, involve affect. Third, that the neural system particularly important for social convention, given its role in mediating anger and responding to angry expressions, is ventrolateral prefrontal cortex. Fourth, that the (...) neural systems particularly important for care-based morality are the amygdala and medial orbital frontal cortex. Fifth, that while Theory of Mind is not a prerequisite for the development of affect-based 'automatic moral attitudes', it is critically involved in many aspects of moral reasoning. (shrink)

Not all of the stimuli that we encounter are unequivocal; some of them may be ambiguous. In a series of two experiments, we investigated how people perceive and assess the emotionality of the words ambiguous on three emotional spaces: valence (dimensions of positivity and negativity), origin (automaticity and reflectiveness), and activation (arousal and subjective significance). Using two types of measurement – behavioural and webcam-based eye tracking – we compared words of moderate and high ambiguity on each of those spaces with (...) control (uniequivocal) words. The behavioural measurements indicated that reaction times were significantly longer for the control words than for all the ambiguous words; the emotionality of words of ambiguous valence and origin was rated as significantly lower than the control words and words of ambiguous activation. The eye-tracking measurements indicated that words of ambiguous valence and origin caused significantly more and longer eye fixations than control words and words of ambiguous activation. The results showed the visible distinctiveness of the ambiguous words compared with the control words; they also showed differences between words of various ambiguities, verifying the proposed new model for the emotional ambiguity and presenting the behavioral and eye tracking correlates for each of the three ambiguities.

Tokenistic short-term economic success is not good indicia of long-term success. Sustainable business success requires sustained existence in a corporation's political, economic, social, technological, legal and environmental contexts. Far beyond the traditional economic focus, consumers, governments and public interest groups alike increasingly expect the business sector to take on more social and environmental responsibilities. Corporate social responsibility (CSR) is the model in which economic, social and environmental responsibilities are fulfilled simultaneously. However, there is insufficient empirical evidence that demonstrates genuine widespread (...) adoption of CSR in practice, and its underlying reasons. Though research in CSR has been rapidly growing, its commercial reality and implications need to be further improved if it is to inspire corporations to voluntarily adopt CSR. In the literature, Carroll's four-dimensional (economic, legal, ethical and discretionary) CSR framework offers a theoretical basis for developing an empirically based model to explain why and how profit-motivated managers take up CSR voluntarily. Our study has developed a structural equation model to identify the key factors and their interactions that influence economically motivated managers to take on voluntary CSR, and validate Carroll's four-dimensional construct. The results support Carroll's four-dimensional CSR framework, with the exception of the link pertaining to the relationship between economic and discretionary/voluntary responsibility. This characterises the economic reality that financial market-driven economic responsibility does not automatically translate into social responsibility. Nevertheless, the empirical results demonstrate that corporations can be led to engage in more voluntary CSR activities to achieve social good when appropriate legal and ethical controls are in place.

The present study investigated whether another individual’s gaze direction influences an observer’s affective responses. In Experiment 1, subjective self-ratings and an affective priming paradigm were employed to examine how participants explicitly and implicitly, respectively, evaluated the affective valence of direct gaze, averted gaze, and closed eyes. The explicit self-ratings showed that participants evaluated closed eyes more positively than direct gaze. However, the implicit priming task showed an inverse pattern of results indicating that direct gaze was automatically evaluated more positively than (...) closed eyes were. Experiment 2 confirmed that the opposite patterns of results between the two tasks were not due to differences in presentation times of the gaze stimuli. The results provide evidence for automatic affective reactions to eye gaze and indicate a dissociation between explicit and implicit affective evaluations of eyes and gaze direction. (shrink)

Barzykowski and Moulin's view on involuntary autobiographical memory focuses on automatic activation of representations and inhibitory control mechanisms.

BackgroundNormally, physicians understand they have a duty to treat patients, and they perform accordingly consistent with codes of medical practice, standards of care, and inner moral motivation. In the case of COVID-19 pandemic in a developing country such as Bangladesh, however, the fact is that some physicians decline either to report for duty or to treat patients presenting with COVID-19 symptoms. At issue ethically is whether such medical practitioners are to be automatically disciplined for dereliction of duty and gross negligence; (...) or, on the contrary, such physicians may legitimately claim a professional right of autonomous judgment, on the basis of which professional right they may justifiably decline to treat patients.MethodsThis ethical issue is examined with a view to providing some guidance and recommendations, insofar as the conditions of medical practice in an under-resourced country such as Bangladesh are vastly different from medical practice in an industrialized nation such as the USA. The concept of moral dilemma as discussed by philosopher Michael Shaw Perry and philosopher Immanuel Kant’s views on moral appeal to “emergency” are considered pertinent to sorting through the moral conundrum of medical care during pandemic.ResultsOur analysis allows for conditional physician discretion in the decision to treat COVID-19 patients, i.e., in the absence of personal protective equipment (PPE) combined with claim of duty to family. Physicians are nonetheless expected to provide a minimum of initial clinical assessment and stabilization of a patient before initiating transfer of a patient to a “designated” COVID-19 hospital. The latter is to be done in coordination with the national center control room that can assure admission of a patient to a referral hospital prior to ambulance transport.ConclusionsThe presence of a moral dilemma (i.e., conflict of obligations) in the pandemic situation of clinical care requires institutional authorities to exercise tolerance of individual physician moral decision about the duty to care. Hospital or government authority should respond to such decisions without introducing immediate sanction, such as suspension from all clinical duties or termination of licensure, and instead arrange for alternative clinical duties consistent with routine medical care.

Correspondence should be addressed to David A. Leopold [email protected] the viewing of certain patterns, widely known as ambiguous or puzzle figures, perception lapses into a sequence of spontaneous alternations, switching every few seconds between two or more visual interpretations of the stimulus. Although their nature and origin remain topics of debate, these stochastic switches are generally thought to be the automatic and inevitable consequence of viewing a pattern without a unique solution. We report here that in humans such perceptual (...) alternations can be slowed, and even brought to a standstill, if the visual stimulus is periodically removed from view. We also show, with a visual illusion, that this stabilizing effect hinges on perceptual disappearance rather than on actual removal of the stimulus. These findings indicate that uninterrupted subjective perception of an ambiguous pattern is required for the initiation of the brain-state changes underlying multistable vision.Visual perception involves coordination between sensory sampling of the world and active interpretation of the sensory data. Human perception of objects and scenes is normally stable and robust, but it falters when one is presented with patterns that are inherently ambiguous or contradictory. Under such conditions, vision lapses into a chain of continually alternating percepts, whereby a viable visual interpretation dominates for a few seconds and is then replaced by a rival interpretation. This multistable vision, or 'multistability', is thought to result from destabilization of fundamental visual mechanisms, and has offered valuable insights into how sensory patterns are actively organized and interpreted in the brain1, 2. Despite a great deal of recent research and interest in multistable perception, however, its neurophysiological underpinnings remain poorly understood. Physiological studies have suggested that disambiguation of ambiguous patterns. (shrink)

The vocabulary for describing odors in English natural language is not well understood, as prior studies of odor descriptions have often relied on preselected descriptors and odor ratings. Here, we present a data-driven approach that automatically identifies English odor descriptors based on their degree of olfactory association, and derive their semantic organization from their distributions in natural texts, using a distributional-semantic language model. We identify 243 descriptors that are much more strongly associated with olfaction than English words in general. We (...) then derive the semantic organization of these olfactory descriptors, and find that it is captured by four clusters that we name Offensive, Malodorous, Fragrant, and Edible. The semantic space derived from our model primarily differentiates descriptors in terms of pleasantness and edibility along which our four clusters are positioned, and is similar to a space derived from perceptual data. The semantic organization of odor vocabulary can thus be mapped using natural language data (e.g., online text), without the limitations of odor-perceptual data and preselected descriptors. Our method may thus facilitate research on olfaction, a sensory system known to often elude verbal description. (shrink)

Here is a fine semipopular book about the ideas which have motivated the much-talked-about revolution in the theories of information, control and communication. Jagjit Singh is one of those rare science writers who knows how to present intricate technical concepts to the less-than-expert reader without compromising the original sense or significance. The book begins, appropriately enough, with a discussion of the concept of information, culminating in the technical definition which enables us to assign numerical values to its quantity. The following (...) chapters present the conceptual heart of the Shannon-Weaver theory, the theories of automatic computing machines and the intriguing neurological theories of Warren McCulloch and John Von Neumann. The chapter on Turing Machines does not pay enough attention to the purely mathematical applications of these devices for the present reviewer's taste. The closing chapters deal with mathematical theories of intelligence and the brain. The text is accompanied by many good drawings and appropriate mathematical demonstrations. A book of this quality could have been produced only by an author with absolute command of his topic.—H. P. K. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 36.3 (2003) 189-206 [Access article in PDF] First Philosophies and Regressive Philosophy Chaïm Perelman "As a crystal reconstitutes itself from one of its particles, all philosophy creates itself from the idea of an open dialectic, and carries, in itself, the same dialectical character." —Ferdinand Gonseth A number of metaphysicians, including Bergson and Heidegger, consider metaphysics the only knowledge of consequence and use the word to refer (...) to their own philosophies. But a large number of eminent metaphysicians, among them Descartes, Spinoza, Kant, Fichte and Hegel had only disdain for metaphysics and used the word to discredit the philosophy of their adversaries. D'Alembert (602-604) once noted that those referred to as metaphysicians had little regard for one another. "I have no doubt," he added, "that this title will soon be an insult to our great minds, just as the name sophist which, although it meant wise, was debased in Greece by those who bore it and rejected by the true philosophers."The preceding remarks should, I think, convince the few who would still doubt it that declaring oneself an adversary of metaphysics does not mean that one does not do metaphysics. On the contrary, the very fact of opposing a certain conception of metaphysics presupposes that one advocates another conception of metaphysics; this needs to be made explicit, if it is only implicit. In a very interesting study, Mr. Everett W. Hall has recently analyzed the metaphysical assumptions of four types of positivism (Mach, Comte, Watson, Carnap). Even without this analysis the conclusion is predictable; he who is opposed to a certain manner of treating a problem remains himself within the same problematic. Indeed, such oppositions produce a continuous expansion and dialogue about the meaning of the word "metaphysics." This happens not through an automatic and necessary dialectic, but through the dialectic directed by the philosopher's concerns.The first metaphysicians set forth a particular philosophy of being [être]; those opposed advocated a different philosophy of being. By expanding its meaning, Aristotle gave metaphysics its first dialectical movement and identified it as the study of being as being and ontology. Kantian criticism treats dogmatic metaphysics with disdain, and shows that all theories [End Page 189] of being must be preceded by a theory of knowledge: the first principles of philosophy would be those of epistemology and not those of ontology. Since Kant, and for more than a century, metaphysical debates would be about the primacy of ontology or epistemology, and the opposition to their variants, realism and idealism. Then, at the end of the nineteenth century, the debate broadened. Under the influence of pragmatism, the philosophy of values, and Bergsonism, a strong current of philosophical thinking developed, which integrated the theory of knowledge into a general theory of action. It proclaimed the primacy of a philosophy of action, philosophy of life, and philosophy of values. It is within a metaphysics broadened by these various developments that different conceptions of metaphysics will struggle to establish the primacy of their principles. But, despite their differences, all of these metaphysics can be considered first philosophies.Aristotle wrote a treatise on first philosophy, the first to be called metaphysics. First philosophies refer to any metaphysics that purports to determine first principles such as the fundamentals of being (ontology), of knowledge (epistemology), or of action (axiology). First philosophies position first principles as absolute and that they underlie all philosophical questions. The word "first" informs the argumentation used to establish the primacy of first philosophies. A principle is first when it comes before all others in a temporal, logical, epistemological or ontological order; the insistence on this point serves to emphasize its primacy or axiologic pre-eminence. That which is first or basic, that which precedes or presupposes all the rest, is also first in order of importance.As systematic metaphysics, first philosophies establish an interdependence among ontology, epistemology, and axiology. The course taken by first philosophies is determined by a starting point constituted by a necessary reality, a self-evident concept, or an absolute value before which one can... (shrink)

The aim of this study was to examine to what extent patients remained silent to the health care system after they experienced abusive or wrongful incidents in health care. Female patients visiting a women’s clinic in Sweden (n = 530) answered the Transgressions of Ethical Principles in Health Care Questionnaire (TEP), which was constructed to measure patients’ abusive experiences in the form of staff’s transgressions of ethical principles in health care. Of all the patients, 63.6% had, at some point, experienced (...) staff’s transgressions of ethical principles, and many perceived these events as abusive and wrongful. Of these patients, 70.3% had remained silent to the health care system about at least one transgression. This silence is a loss of essential feedback for the health care system and should not automatically be interpreted as though patients are satisfied. (shrink)

Automatized scalable healthcare support solutions allow real-time 24/7 health monitoring of patients, prioritizing medical treatment according to health conditions, reducing medical appointments in clinics and hospitals, and enabling easy exchange of information among healthcare professionals. With recent health safety guidelines due to the COVID-19 pandemic, protecting the elderly has become imperative. However, state-of-the-art health wearable device platforms present limitations in hardware, parameter estimation algorithms, and software architecture. This paper proposes a complete framework for health systems composed of multi-sensor wearable health (...) devices, high-resolution parameter estimation, and real-time monitoring applications. The framework is appropriate for real-time monitoring of elderly patients' health without physical contact with healthcare professionals, maintaining safety standards. The hardware includes sensors for monitoring steps, pulse oximetry, heart rate, and temperature using low-power wireless communication. In terms of parameter estimation, the embedded circuit uses high-resolution signal processing algorithms that result in an improved measure of the HR. The proposed high-resolution signal processing-based approach outperforms state-of-the-art HR estimation measurements using the photoplethysmography sensor. (shrink)
