Positive frequency dependent selection is a natural selection regime where the fitness of a phenotype increases with its frequency in the population. Examples can be typically found in the spread of disease tolerance strategies in a population. A characterizing feature of PFDS is that the focal allele may experience favorable selection only when it becomes more frequent in the population, while being selected against when it is rare. In this paper, by applying a solution concept from evolutionary game (...) theory, we hypothesize that the process of emergence of such alleles triggers selection for silence, where the emergence of alleles that can stay unexpressed for a period of time will be favored by selection forces. We illustrate our hypothesis using a mathematical model of a population of single locus diploid organisms with two alleles where a single mutant of an allele that experiences positive frequency dependent selection appears in a population where the other allele is a dominant. The model results show that the longer the silence interval of the new mutant before its expression, the better its chances of getting fixed in the population. However, this effect will be observable only to a certain limit after which further increase in the interval will not have an effect on the expected fixation rate. Two divergences from the simple scenario are also investigated: the nonsynchronous expression of the focal allele and its emergence in a spatial grid limited by a migration bottleneck. In all cases, it is shown that there is an evolutionary pressure inherent in the dynamics of positive frequency dependent selection on the genes to have a delayed expression. It is hypothesized that the regulation systems of such traits will be under selection for either internal silencing mechanisms or to be triggered by an external environmental condition. (shrink)

ABSTRACTEmotional distractors can impair perception of subsequently presented targets, a phenomenon called emotion-induced blindness. Do emotional distractors lose their power to disrupt perception when appearing with increased frequency, perhaps due to desensitisation or enhanced recruitment of proactive control? Non-emotional tasks, such as the Stroop, have revealed that high frequency distractors or conflict lead to reduced interference, and distractor frequency appears to modulate attentional capture by emotional distractors in spatial attention tasks. But emotion-induced blindness is thought to reflect (...) perceptual competition between targets and emotional distractors, and it is unclear whether high frequency emotional stimuli cause less disruption at this relatively early stage of processing. In four experiments, participants searched streams of images for a rotated target image. A negative or neutral distractor appeared before the target, and their relative frequency was manipulated. Across all exper... (shrink)

The present study intended to investigate, first, the impact of semantic clustering on the recall and recognition of incidentally learned words in a new language, and second, how the interaction between semantic clustering and frequency of occurrence may modulate learning. To that end, Spanish university students watched an intentionally created video which contained Spanish target words that were either semantically related to others of the set, or not semantically linked at all. Furthermore, frequency of appearance changed among (...) target words (1|4|8). All these words were paired with pseudowords that appeared as on-screen text during the videos. Participants were completely naive to the phases and the procedure of the experiment. After viewing the video, participants completed a recall test and a recognition test. Results showed that words presented in semantically unrelated categories were better recalled and better recognized than those presented in semantic clusters, especially when the words were presented more often.

Increasing psychophysical evidence suggests that specific image features - or statistics - can appear unpleasant or induce visual discomfort in humans. Such unpleasantness tends to be particularly profound if the image's amplitude spectrum deviates from the regular 1/f spatial-frequency falloff expected in natural scenes. Here, we show that profound unpleasant impressions also result if the orientation spectrum of the image becomes flatter. Using bandpass noise with variable orientation and spatial-frequency bandwidths, we found that unpleasantness ratings decreased with spatial- (...) frequency bandwidth but increased with orientation bandwidth. Similarly, a subsequent experiment revealed that sinusoidal modulations in the amplitude spectrum of 1/f noise along the spatial frequency increased unpleasantness, but modulations along the orientation decreased it. Given that natural scenes tend to have a linear slope along the spatial frequency but an uneven spectrum along the orientation dimension, our opposing results in the spatial-frequency and orientation domains commonly support the idea that images deviating from the spectral regularity of natural scenes can give rise to unpleasant impressions.

Prior research has shown that people can learn many nouns from a short series of ambiguous situations containing multiple words and objects. For successful cross-situational learning, people must approximately track which words and referents co-occur most frequently. This study investigates the effects of allowing some word-referent pairs to appear more frequently than others, as is true in real-world learning environments. Surprisingly, high-frequency pairs are not always learned better, but can also boost learning of other pairs. Using a recent associative (...) model, we explain how mixing pairs of different frequencies can bootstrap late learning of the low-frequency pairs based on early learning of higher frequency pairs. We also manipulate contextual diversity, the number of pairs a given pair appears with across training, since it is naturalistically confounded with frequency. The associative model has competing familiarity and uncertainty biases, and their interaction is able to capture the individual and combined effects of frequency and contextual diversity on human learning. Two other recent word-learning models do not account for the behavioral findings. (shrink)

The hallmark of implicit learning is that complex knowledge can be acquired unconsciously. The second order conditionals of Reed and Johnson were developed to be complex, and they are popular materials for implicit learning research. Recently, it was demonstrated that in a sequence made noisy , shared features of the SOCs may be learned explicitly . What are these shared features? We hypothesized that low reversal frequency may play a significant role. We have varied reversal frequency, and discovered (...) that reversal frequency affected response times, inclusion exclusion behavior, and recognition ratings. Not only does it appear to be important to distinguish implicit and explicit knowledge, but also to distinguish what the knowledge is of. (shrink)

The frequency of the use of deception in American psychological research was studied by reviewing articles from journals in personality and social psychology from 1921 to 1994. Deception was used rarely during the developmental years of social psychology into the 1930s, then grew gradually and irregularly until the 1950s. Between the 1950s and 1970s the use of deception increased significantly. This increase is attributed to changes in experimental methods, the popularity of realistic impact experiments, and the influence of cognitive (...) dissonance theory. Since 1980 there appears to have been a decrease in the use of deception as compared to previous decades which is related to changes in theory, methods, ethical standards, and federal regulation of research.

The frequency of discriminatory language in job advertisements placed by U. S. multinational corporations operating in Mexico was compared with that of Mexican companies using content analysis. A sample of 300 ads placed by companies from each culture was analyzed and coded by two groups of coders to calculate the frequency of discriminatory language in the job ads with respect to age, gender, physical appearance and marital status. Results of a chi square analysis revealed that U. S.

This result suggests that the legal and cultural framework of the country of origin of U. S. enterprises in Mexico may be influencing their actual recruitment practice in Mexico, and in turn, help them in setting a positive example of non-discrimination in recruitment among their Mexican counterparts.

'This excellent collection provides the reader with a comprehensive coverage of findings and theories about how people encode and summarize frequency information. While it is a smorgasbord of self-contained chapters with little cross-referencing, the high quality of the vast majority of these chapters yields a cognitive feast. They are written by eminent researchers who have opted to present both recent results and summaries of their most important work - certainly not the feared secondary idea or paper submitted because it (...) would be easier to publish in an edited volume than in critically peer reviewed journal.' Robyn M. Dawes, Charles J. Queenan, Jr. University Professor, Department of Social and Decision Sciences, Carnegie Mellon University, USAFrom childhood, each of us develops our own personal set of theories and beliefs about the world in which we live. Given the impossibility of knowing about every event that can ever take place, we use cognitive short cuts to try to predict and make sense of the world around us. One of the fundamental pieces of information we use to predict future events, and make sense of past events, is 'frequency' - how often has such an event happened to us, or how often have we observed a particular event? With such information we will make inferences about the likelihood of its future appearance. We will make judgements, assess risk, or even consumer decisions, on the basis of this information. We also form associations between events that frequently occur together, and even attribute causality between one event and the other as a result of their simultaneous appearance. How is it though that we process such information? How does our brain deal with information on frequencies? How does such information influence our behaviour, beliefs, and judgements? Important new findings on this topic have come from research within both social and cognitive psychology, though until now, never brought together in a single volume. This is the first book to bring together two disparate literatures on this topic - drawing on research from both cognitive psychology and social psychology. Including contributions from world leaders in the field, this is a timely, and long overdue volume on this topic. (shrink)

This essay sounds out Derrida's plurivocal term of frequencies as well as Nancy's understanding of resonance to argue that ghosts live in the ear. Heeding how the different nuances of this term bear on Derrida's reading of Hamlet, it not only seeks to understand the significance of the ghost's rhythmic appearance:disappearance in Shakespeare's play, but indeed, how it comes to frequent Derrida's Specters of Marx.

Aging is associated with decreased functional connectivity in the main brain networks, which can underlie changes in cognitive and emotional processing. Neurofeedback is a promising non-pharmacological approach for the enhancement of brain connectivity. Previously, we showed that a single session of infra-low frequency neurofeedback results in increased connectivity between sensory processing networks in healthy young adults. In the current pilot study, we aimed to evaluate the possibility of enhancing brain connectivity during aging with the use of infra-low frequency (...) neurofeedback. Nine females aged 52 ± 7 years with subclinical signs of emotional dysregulation, including anxiety, mild depression, and somatoform symptoms, underwent 15 sessions of training. A resting-state functional MRI scan was acquired before and after the training. A hypothesis-free intrinsic connectivity analysis showed increased connectivity in regions in the bilateral temporal fusiform cortex, right supplementary motor area, left amygdala, left temporal pole, and cerebellum. Next, a seed-to-voxel analysis for the revealed regions was performed using the post- vs. pre-neurofeedback contrast. Finally, to explore the whole network of neurofeedback-related connectivity changes, the regions revealed by the intrinsic connectivity and seed-to-voxel analyses were entered into a network-based statistical analysis. An extended network was revealed, including the temporal and occipital fusiform cortex, multiple areas from the visual cortex, the right posterior superior temporal sulcus, the amygdala, the temporal poles, the superior parietal lobule, and the supplementary motor cortex. Clinically, decreases in alexithymia, depression, and anxiety levels were observed. Thus, infra-low frequency neurofeedback appears to be a promising method for enhancing brain connectivity during aging, and subsequent sham-controlled studies utilizing larger samples are feasible.

Introduction Hospital delirium is a frequent, serious, costly, and underrecognized acute disorder of attention and cognition. Therefore, the prevention of hospital delirium is not only desirable for patients, caregivers, healthcare professionals, and the health system itself, but also a moral duty. Objective To identify and synthetize the main ethical aspects that arise related to the prevention of hospital delirium in patients 65 years and older. Methods A scoping review was carried out in Embase, Medline, and Web of Science. Articles published (...) in English or Spanish analyzing any pharmacologic, non-pharmacologic, or multicomponent intervention for prevention of delirium in hospitalized patients aged 65 years and over were included. Results Twenty-seven studies were included. Based on the frequency of appearance and the relevance, our findings were organized into three main areas. The first one was related to the principle of nonmaleficence and collected findings about the iatrogenic causes of hospital delirium and the use of restraints systems. The second area analyzed the impact of delirium in patients, families, and healthcare professionals from a relational ethics perspective, and addressed the family presence as a factor to prevent delirium. Finally, the third area is related to the quality of care. Conclusion Prevention of delirium in hospitals is essential to avoid the discomfort and potential clinical complications of patients, as well as the suffering of their relatives, caregivers, and healthcare professionals. Policymakers and healthcare managers are encouraged to make the required efforts to prevent delirium in hospitalized older patients. (shrink)

Sexually signalling animals must trade off the benefits of attracting mates with the consequences of attracting predators. For male guppies, predation risk depends on their behaviour, colouration, environmental conditions and changing intensity of predation throughout the day. Theoretically, this drives diel patterns of display behaviour in native Trinidadian populations, where males display more under low-light conditions when their most dangerous predator is less active. Here, we observed Australian guppies in a laboratory setting to investigate their diel display pattern, and if (...) this pattern is controlled by ambient light intensity. We also quantified individual variation in both the daily frequency and diel pattern of displays, and if such variation relates to body size, colouration and a non-sexual behaviour. Under a typical daily light regime, male guppies displayed mostly in the first hour of observation. Extending the duration of dawn-like lighting, however, resulted in an extended period of high display, demonstrating that light intensity per se is an important cue for this behaviour. These findings mirror those obtained for Trinidadian populations, suggesting that male courtship timing is likely shaped by broad, potentially generalizable features of guppy ecology. The effect of acclimation to captive conditions on male behaviour is also discussed. Whereas the temporal pattern of display appeared consistent, individuals varied in their daily display frequency, and this was correlated with variation in colour phenotype and a measure of non-sexual risk acceptance behaviour. Such relationships pose promising avenues for integrating behavioural and sensory ecology with contemporary work on behavioural syndromes and animal personality. (shrink)

The thesis argues that a basic ontology of dóxa and appearances (and more in general mental episodes) can be gleaned from a careful analysis of Plato's early dialogues. To this aim, the first part (chapter 1) discusses the main issues concerning Plato's language of dóxa and appearances, both from the linguistic and from the philosophical point of view, and argues that dóxa is best understood as judgement. The second part develops a three-stage argument: chapter 2 argues that dóxa and appearances (...) are for Plato affections (páthe); chapter 3 that affections are for Plato fundamentally relational events; chapter 4 that, therefore, appearances are for Plato fundamentally relational events. The third and last part (chapter 5) investigates Plato's ontology of evaluative appearances (and desire) by focussing on the interplay between the ontology of appearances and the ontology of values (“goods and evils”) as one can extract it from the dialogue Gorgias. The three parts are secluded within a general introduction and conclusions. Four appendices complement the thesis with: a philosophical glossary of mental events; a table of frequencies of terms for mental episodes in the Platonic corpus; a list of all the occurrences of 'phaínomai' and 'dokéo' in the early dialogues; and a semi-formal appendix discussing the logical form of Plato's statements about metaphysical explanations.

Objective: To describe the frequency of support for terminal sedation among internists, determine whether support for terminal sedation is accompanied by support for physician assisted suicide , and explore characteristics of internists who support terminal sedation but not assisted suicide.Design: A statewide, anonymous postal survey.Setting: Connecticut, USA.Participants: 677 Connecticut members of the American College of Physicians.Measurements: Attitudes toward terminal sedation and assisted suicide; experience providing primary care to terminally ill patients; demographic and religious characteristics.Results: 78% of respondents believed that (...) if a terminally ill patient has intractable pain despite aggressive analgesia, it is ethically appropriate to provide terminal sedation . Of those who favoured terminal sedation, 38% also agreed that PAS is ethically appropriate in some circumstances. Along a three point spectrum of aggressiveness in end of life care, the plurality of respondents were in the middle, agreeing with terminal sedation but not with PAS. Compared with respondents who were less aggressive or more aggressive, physicians in this middle group were more likely to report having more experience providing primary care to terminally ill patients and attending religious services more frequently .Conclusions: Support for terminal sedation was widespread in this population of physicians, and most who agreed with terminal sedation did not support PAS. Most internists who support aggressive palliation appear likely to draw an ethical line between terminal sedation and assisted suicide. (shrink)

Heterosexist ideology underpins education policy and practice almost universally. It has the effect of rendering invisible and disrespecting practitioners and students of other sexual and non-gender conforming identities. Much explicitly queer work has challenged this normalising and frequently oppressive higher education terrain. To maximise this queer potential this article proposes re-positioning queer within and through a practice and pedagogy of feminism. The broad-based identity politics of feminism and the anti-identitarian politic of queer may appear a slightly improbable alliance. The article (...) argues, however, that intersectional approaches which reinforce queer integrity, challenge oppressive social norms and simultaneously re-emphasise the importance of the political through an identity politics heavily influenced by feminism, are not just possible but necessary. In seeking to explore what unites feminism and queer educationally, the article makes three observations relating to history, pedagogy and activism. It references two particular LGTBQ Irish and European educational programmes, which it argues highlight this sense of the probable in terms of queer–feminist educational alliances. Such alliances can continue to challenge in material ways sustained educational constructions of heterosexuality as normal, natural and moral and in so doing provide a platform for empowerment and change.

The prevalence of dementia is increasing with the ever-growing population of older adults. Non-pharmacological, music-based interventions, including sensory stimulation, were reported by the Lancet Commission in 2020 to be the first-choice approach for managing the behavioural and psychological symptoms of dementia. Low frequency sinusoidal vibration interventions, related to music interventions through their core characteristics, may offer relief for these symptoms. Despite increasing attention on the effectiveness of auditory music interventions and music therapy for managing dementia, this has not included (...) low frequency vibration. This scoping review, following the JBI methodology guidelines, was conducted to investigate participants’ responses to both sound and mechanical vibration, the characteristics of the delivered interventions, methodological challenges, and the specifics of the research experiments reported. An extensive search was conducted in BMC, CINAHL, Cochrane Central Register of Controlled Trials, EMBASE, ERIC, MEDLINE, Pedro, ProQuest Central, PsycINFO, Scopus, and Web of Science. Current Controlled Trials, Clinical Trials, and Google Scholar were also searched as well as a hand search in relevant journals. Studies on adults with all types of dementia, investigating tactile low frequency sound or mechanical vibration in any context were considered. Data from eight full-length studies were extracted using the data extraction table developed by the authors and were included in the analysis and critical appraisal. Issues in quality related to, for example, control groups and blinding. Few studies addressed participants’ subjective responses to the interventions. Reporting on the intervention characteristics was unclear. It appeared more frequent sessions led to better outcomes and home-based interventions potentially addressing the issue of access and feasibility. Future research should include neuroimaging to measure and confirm the hypothesised mechanism of cerebral coherence. Standardised reporting of intervention characteristics is also needed to ensure replicability of the experiments. Higher quality research is needed to investigate the impact and effect of low frequency vibration for the symptoms of dementia and compare outcomes in meta-syntheses. (shrink)

Scientific journals can promote ethical publication practices through policies on conflicts of interest. However, the prevalence of conflict of interest policies and the definition of conflict of interest appear to vary across scientific disciplines. This survey of high-impact, peer-reviewed journals in 12 different scientific disciplines was conducted to assess these variations. The survey identified published conflict of interest policies in 28 of 84 journals (33%). However, when representatives of 49 of the 84 journals (58%) completed a Web-based survey about journal (...) conflict of interest policies, 39 (80%) reported having such a policy. Frequency of policies (including those not published) varied by discipline, from 100% among general medical journals to none among physics journals. Financial interests were most frequently addressed with relation to authors; policies for reviewers most often addressed non-financial conflicts. Twenty-two of the 39 journals with policies (56%) had policies about editors’ conflicts. The highest impact journals in each category were most likely to have a published policy, and the frequency of policies fell linearly with rank; for example, policies were published by 58% of journals ranked 1 in their category, 42% of journals ranked third, and 8% of journals ranked seventh (test for trend, p = 0.003). Having a conflict of interest policy was also associated with a self-reported history of problems with conflict of interest. The prevalence of published conflict of interest policies was higher than that reported in a 1997 study, an increase that might be attributable to heightened awareness of conflict of interest issues. However, many of the journals with policies do not make them readily available and many of those policies that were available lacked clear definitions of conflict of interest or details about how disclosures would be managed during peer review and publication.

Causal processes can give rise to distinctive distributions in the linguistic variables that they affect. Consequently, a secure understanding of a variable's distribution can hold a key to understanding the forces that have causally shaped it. A storied distribution in linguistics has been Zipf's law, a kind of power law. In the wake of a major debate in the sciences around power-law hypotheses and the unreliability of earlier methods of evaluating them, here we re-evaluate the distributions claimed to characterize phoneme (...) frequencies. We infer the fit of power laws and three alternative distributions to 166 Australian languages, using a maximum likelihood framework. We find evidence supporting earlier results, but also nuancing them and increasing our understanding of them. Most notably, phonemic inventories appear to have a Zipfian-like frequency structure among their most-frequent members (though perhaps also a lognormal structure) but a geometric (or exponential) structure among the least-frequent. We compare these new insights the kinds of causal processes that affect the evolution of phonemic inventories over time, and identify a potential account for why, despite there being an important role for phonetic substance in phonemic change, we could still expect inventories with highly diverse phonetic content to share similar distributions of phoneme frequencies. We conclude with priorities for future work in this promising program of research. (shrink)

On the analogy of the colloquial register in some modern languages, where narrative and argument may be punctuated by oaths and exclamations (sometimes obscene or blasphemous) in order to maintain a high affective level and compel the hearer's attention, it is reasonable to postulate that Attic conversation also was punctuated by oaths, that this ingredient in comic language was drawn from life, and that the comparative frequency of ║ (|)M M(M) Δ in comedy is sufficiently explained thereby. There are (...) obvious affinities between some passages of comedy, relaxed conversation in Plato and Xenophon, and the forceful, man-to-man tone which Demosthenes sometimes adopts to such good effect (e.g. xxi 209). Compare, for instance, Ar.V.133 f.ἔστιν δ' ⋯νομα ⋮ τῷ μ⋯ν γέροντι ⋮ Φιλοκλέων / να⋯ μ⋯ Δία, τῷ δ' υἱεῖ κτλ., where the oath is a response to imagined incredulity, and X.Smp.4.27αὐτ⋯ν δ⋯ σέ, ἔɸη, ⋯γὼ εἶδον να⋯ μ⋯ τ⋯ν Ἀπόλλω, ὅτε κτλ. (‘Oh, yes, I did!’).It is also important that the commonest oaths fit, in most of their forms, the end of an iambic trimeter:(να⋯) μ⋯ τ⋯ν Δία, ν⋯ (τ⋯ν) Δία,ν⋯ τούς θεούς, μ⋯ τοὺς θεούς. Add that in Aristophanic dialogue (by contrast with Menander) over half the iambic trimeters end with major pause, and half the remainder with minor pause, and we can see why Δ / established itself early as a distinctive comic pattern. Out of 105 examples ofM M(M) Δ cited from comedy in Section II above, 59 have the oath at verse-end.In the case ofπάνυ, which was almost exclusively Attic and — to judge from its great rarity in tragedy — felt by Athenian poets to be prosaic, we lack evidence on its functions in the colloquial register; it may or may not have served as affective punctuation. In prose, we have to reckon with the fact thatπ MπandMππconstituted a genuine stylistic choice (cf. n. 32) as far back as the evidence will take us, since the two earliest instances in prose are [X.]Ath.2.3πάνυ δι⋯ χρείανand ibid. 3.5πολλ⋯ ἔτι πάνυ. The oath, as treated by the comic poets on the basis of colloquial usage, is bound to have served as a model forπάνυ, exerting an influence which pulledπάνυto the end of the verse, but there was also a powerful metrical constraint. As a dibrach ending in a vowel which could not be elided or enter into crasis,πάνυwas especially appropriate for verse-end. That in itself was enough both to establishMππas the dominant pattern in comedy and to promoteMπ…π. Out of the total of 104 examples ofMπ(…)πin comedy, 93 haveπάνυat verse-end, which makesMπ(…)π/ one of the hallmarks of comic style.Mπ…πdoes not occur in prose in association with any other feature identified as colloquial, but it should be noted that Aiskhines and Demosthenes are much fonder ofMππthan other prose authors. In some cases one can see that the orderMππavoids a succession of short syllables (e.g. D. xviii 130, liv 1) or hiatus (e.g. D. xxx 36) or both (e.g. D. xliii 10), but there are other cases in which it has the opposite effect (e.g. D. xxiv 140, xliii 53). The possibility of comic influence on oratorical language cannot be dismissed out of hand. It is also possible that someone will find positive determinants which will explain all the cases ofMππin prose.σɸόδρα, which, likeπάνυ, is peculiarly Attic, is metrically more tractable thanπάνυ, since it can be elided; even so, out of the 80 comic examples ofMσ(…) σ no less than 58 haveσɸόδραat verse-end, and of those 58 there are 22 at major pause, 8 at presumed major pause and 9 at minor pause. The comic treatment ofσɸόδραis thus comparable with the treatment ofπάνυ, and Timokles (CGFP) 222(b).4τηρεῖν…σɸόδραis in fact the closest analogy we have to Ar.Pl.234 f.ἄχθομαι…πάνυ.δέandγάρare a different matter, and in some significant respects different from each other. Postponement ofδέis especially prominent in Aeschylus (45 examples, including a few in which the text is suspect) and then abundant in fourth-century comedy. It is much less common in Euripides (18 examples), rare in Sophocles (6) and Aristophanes (6), and virtually limited in prose to the categories which I labelled (l)–(3). There is as yet no evidence to associate postponement ofδέwith colloquial language; on the contrary, it seems to have begun as a feature of poetic language and to have been taken up and exploited by fourth-century comedy. If, in addition to being Aeschylean, it was colloquial in the fourth century, what happened to it afterwards? Except for such an isolated and inexplicable case as Diod. xx85.1 (v.l.!) — in a military narrative — it is not a feature of the Koine at literary, documentary or subliterate level.Postponement ofγάρwas no doubt encouraged by postponement ofδέ, but it is not itself notably poetic (20 examples in tragedy, of which only three come in my class (5)). One can see how it could possibly have developed in the spoken language of the fourth century, extending the function ofγάρas an explanatory particle (rather on the lines ofγε) in a way which makes it comparable with the English ‘you see’ in (e.g.) ‘He didn't dare pick it up. He hurt his back last year, you see’. For an extension of this kind we may compare the current extension of the English genitive affix in (I heard both examples a year or two ago) ‘Then the girl whose place she was taking's mother turned up’ and ‘The man that Christopher liked's Introduction is much better’. Moreover, postponedγάρappears in a segment of conversation constructed in indirect speech by Theophrastus inChar.8.9τ⋯ πρ⋯γμα βο⋯σθαι γάρ(p C N γάρ). Again we must ask: what happened to it afterwards? A couple of cases in Theophrastus' botanical works (CPiii 11.3 andHPiv 6.1) could be a reflex of the influence of comedy on literary language at Athens. The influence was plainly short-lived, since it did not affect the Koine.It is not hard to see why serious poetry in the fifth century and earlier should have experimented occasionally with the postponement ofδέandγάρ: treatment ofM M qas a valid alternative toM q Mis metrically very convenient. No poet, however, could afford to use common words in a bizarre, un-Greek way merely to save himself time and trouble in constructing a verse. Linguistic innovation is normally analogical, proceeding by extension from a starting-point already there, and the most obvious starting-point for postponement ofδέandγάρis constituted by my class (3). This consideration provides comic postponement with a pedigree, but does not deny it individuality. The remarkable scale and frequency with which comedy exploited a phenomenon which tragedy used with restraint and prose hardly at all gives comic postponement the right to be regarded as a quite distinctive artificial feature of comedy.

This study employs an experiment investigating cognitive mapping of fifth-grade children living in a remote village environment, wherein characteristics of the landscape included paths, landmarks, nodes, edges, and districts. Two aspects of analysis were salient in this study. First, important landscape characteristics and their frequency of appearance in the cognitive maps were tabulated and illustrated as a layout map. Second, inaccurate cognitive maps were structurally analyzed to account for any incompleteness, distortions, and augmentation of actual environments found in (...) some map samples. Focus on gender differences in children’s environmental cognition in terms of symbolic representation skills utilized in cognitive mapping is of special interest in this case study. Results confirm Piaget’s theory that older children, aged ten or more, begin to use projective and Euclidean concepts. Furthermore, boys used a greater variety of symbols to represent a particular landscape characteristic, a cultural temple, than did the girls. Finally, we hypothesize that the ‘hunter–gatherer’ social divisions of labor between men and women in the village’s early historical social structure are consequentially related to gender discrepancies in cognitive mapping symbolic representation skills, in non-English-speaking children.

Chance-based gambling has been a recurrent cultural activity throughout history and across many diverse human societies. In this paper, I combine quantitative and qualitative data and present a cultural evolutionary framework to explain why the odds in games of chance in premodern China appeared “designed” to ensure a moderate yet favorable house advantage. This is especially intriguing since extensive research in the history of probability has shown that, prior to the development of probability theory, people had very limited understanding of (...) the nature of random events and were generally disinclined to think mathematically about the frequency of their occurrence. I argue that games of chance in the context of gambling may have culturally evolved into their documented forms via a process of selective imitation and retention, and neither the customers nor the gambling houses understood the probability calculus involved in these games.

Our understanding of human visual perception generally rests on the assumption that conscious visual states represent the interaction of spatial structures in the environment and our nervous system. This assumption is questioned by circumstances where conscious visual states can be triggered by external stimulation which is not primarily spatially defined. Here, subjective colors and forms are evoked by flickering light while the precise nature of those experiences varies over flicker frequency and phase. What’s more, the occurrence of one subjective (...) experience appears to be associated with the occurrence of others. While these data indicate that conscious visual experience may be evoked directly by particular variations in the flow of spatially unstructured light over time, it must be assumed that the systems responsible are essentially temporal in character and capable of representing a variety of visual forms and colors, coded in different frequencies or at different phases of the same processing rhythm.

Anderson localization of electromagnetic waves in three-dimensional disordered dielectric structures is studied using a simple yet realistic theoretical model. An effective approach based on analysis of probability distributions, not averages, is developed. The disordered dielectric medium is modeled by a system of randomly distributed electric dipoles. Spectra of certain random matrices are investigated and the possibility of appearance of the continuous band of localized waves emerging in the limit of an infinite medium is indicated. It is shown that localization (...) could be achieved without tuning the frequency of monochromatic electromagnetic waves to match the internal (Mie-type) resonances of individual scatterers. A possible explanation for the lack of experimental evidence for strong localization in 3D as well as suggestions how to make localization experimentally feasible are also given. Rather peculiar requirements for setting in localization in 3D as compared to 2D are indicated. (shrink)

Recent theories of cognition have argued that embodied experience is important for conceptual processing. Embodiment can be contrasted with linguistic factors such as the typical order in which words appear in language. Here, we report four experiments that investigated the conditions under which embodiment and linguistic factors determine performance. Participants made speeded judgments about whether pairs of words or pictures were semantically related or had an iconic relationship. The embodiment factor was operationalized as the degree to which stimulus pairs were (...) presented in the spatial configurations in which they usually occur (i.e., an iconic configuration, e.g., attic presented above basement). The linguistic factor was operationalized as the frequency of the stimulus pairs in language. The embodiment factor predicted error rates and response time better for pictures, whereas the linguistic factor predicted error rates and response time better for words. These findings were modified by task, with the embodiment factor being strongest in iconicity judgments for pictures and the linguistic factor being strongest in semantic judgments for words. Both factors predicted error rates and response time for both semantic and iconicity judgments. These findings support the view that conceptual processing is both linguistic and embodied, with a bias for the embodiment or the linguistic factor depending on the nature of the task and the stimuli.

More recently, grammaticalization theorists have become increasingly aware of the role of collocations in grammatical development. One of these roles is to define phonetic reductions and fusion in frequent collocations as constructionalization. Based on frequency of occurrences, the present study explores the implications of high-frequency collocations in Turkish Sign Language for grammaticalization and offers a novel account of constructional change of değİl ‘not’ on usage-based grounds. Specifically, the study suggests that (i) the chunking process is not language-specific within (...) the spoken modality, as noted previously in the literature, (ii) the frequency of collocations is strongly correlated with phonetic reduction and duration, (iii) the fusional characteristics of [sign + değİl] collocations can be classified under four reduced constructional schemas, (iv) the monosyllabicity of a scheme appears to be criterion for it to be productive in signed modality and (v) the semantic changes of frequent [sign + değİl] collocations are related to the notion of subjectification in TİD.

Simulation process and mirroring mechanism appear to be necessary to the recognition of emotional facial expressions. Prefrontal areas were found to support this simulation mechanism. The present research analyzed the role of premotor area in processing emotional faces with different valence , considering both conscious and unconscious pathways. High-frequency rTMS stimulation was applied to prefrontal area to induce an activation response when overt and covert processing was implicated. Twenty-two subjects were asked to detect emotion/no emotion . Error rates and (...) response times were considered in response to the experimental conditions. ERs and RTs decreased in case of premotor brain activation, specifically in response to fear, for both conscious and unconscious condition. The present results highlight the role of the premotor system for facial expression processing, supporting the existence of two analogous mechanisms for conscious and unconscious condition. (shrink)

Previous research indicates that birth order is a strong predictor of familial sentiments, with middleborns less family-oriented than first- or last-borns. In this research, effects of sex and birth order on the actual frequency of contact with maternal and paternal kin were examined in two studies. In Study 1, one hundred and forty undergraduates completed a questionnaire relating to the amount of time they spent in contact with specific relatives, while in Study 2, one hundred and twelve undergraduates completed (...) the same questionnaire with the addition of two questions relating to the subjects’ parents’ birth orders. Subjects were more likely to have frequent contact with maternal, as opposed to paternal, kin and women experienced more frequent contact than men with relatives in general. The birth order of subjects did not appear to have a significant influence on contact but the birth order of the subjects’ parents did, with the offspring of middleborn mothers having relatively little contact with maternal grandparents and the offspring of middleborn fathers having relatively little contact with paternal grandparents. These sex and birth order differences are discussed in relation to possible differences in how women and men use kinship ties and in terms of how birth order may influence parental solicitude.

Prevailing theories of the neural basis of at least a subset of individuals with autism spectrum disorder include an imbalance of excitatory and inhibitory neurotransmission. These circuitry imbalances are commonly probed in adults using auditory steady-state responses to elicit coherent electrophysiological responses from intact circuitry. Challenges to the ASSR methodology occur during development, where the optimal ASSR driving frequency may be unknown. An alternative approach is the amplitude-modulated sweep in which the amplitude of a tone is modulated as a (...) sweep from 10 to 100 Hz over the course of ∼15 s. Phase synchrony of evoked responses, measured via intra-trial coherence, is recorded as a function of frequency. We applied such AM sweep stimuli bilaterally to 40 typically developing and 80 children with ASD, aged 6–18 years. Diagnoses were confirmed by DSM-5 criteria as well as autism diagnostic observation schedule observational assessment. Stimuli were presented binaurally during MEG recording and consisted of 20 AM swept stimuli with a duration of ∼30 s each. Peak intra-trial coherence values and peak response frequencies of source modeled responses were examined. First, the phase synchrony or inter-trial coherence of the ASSR is diminished in ASD; second, hemispheric bias in the ASSR, observed in typical development, is maintained in ASD, and third, that the frequency at which the peak response is obtained varies on an individual basis, in part dependent on age, and with altered developmental trajectories in ASD vs. TD. Finally, there appears an association between auditory steady-state phase synchrony and clinical assessment of language ability/impairment. We concluded that the AM sweep stimulus provides a mechanism for probing ASSR in an unbiased fashion, during developmental maturation of peak response frequency, peak frequencies vary, in part due to developmental age, and importantly, ITC at this peak frequency is diminished in ASD, with the degree of ITC disturbance related to clinically assessed language impairment.

Although classical probability theory, as it is encapsulated in the axioms of Kolmogorov and in his criterion for the independence of two events, can consistently be employed in quantum mechanics, this can only be accomplished at an exorbitant price. By considering first the classic two‐slit experiment, and then the passage of one photon through three polarizers, the applicability of Kolmogorov's last axiom is called into question, but the standard rebuff of the Copenhagen interpretation is shown to be adequate to this (...) challenge. In the EPR experiment of Aspect, and the violation of the Bell inequalities, the matter is more delicate: it is not directly Kolmogorov's last axiom, but rather his criterion of independence that is at issue. It is explained how two events with space‐like separation cannot be independent in Kolmogorov's sense, even in the presence of hidden variables. The escape route of supposing the variables to be nonlocal, with a heavy metaphysical ballast of holism, which however is cosmically censored to prevent superluminal information transfer, has all the trappings of an ad hoc makeshift. The adoption of quantum mechanical probability, which does not obey the rules of Kolmogorov, but does survive empirical testing in terms of relative frequencies of events, is more economical. The solution is simple: correlations obey the rules of quantum mechanics and probability is a theory laden concept that is tested by, but not defined in terms of, the relative frequency of selected classes of events. Quantum mechanics appears to be nonlocal only if one tries to force it into a classical, realist straitjacket. However, this is a shortcoming of the straitjacket: it is not a property of quantum mechanics. That follows from the fact that a Bell telephone does not work! (shrink)

Children show a remarkable degree of consistency in learning some words earlier than others. What patterns of word usage predict variations among words in age of acquisition? We use distributional analysis of a naturalistic corpus of child‐directed speech to create quantitative features representing natural variability in word contexts. We evaluate two sets of features: One set is generated from the distribution of words into frames defined by the two adjacent words. These features primarily encode syntactic aspects of word usage. The (...) other set is generated from non‐adjacent co‐occurrences between words. These features encode complementary thematic aspects of word usage. Regression models using these distributional features to predict age of acquisition of 656 early‐acquired English words indicate that both types of features improve predictions over simpler models based on frequency and appearance in salient or simple utterance contexts. Syntactic features were stronger predictors of children's production than comprehension, whereas thematic features were stronger predictors of comprehension. Overall, earlier acquisition was predicted by features representing frames that select for nouns and verbs, and by thematic content related to food and face‐to‐face play topics; later acquisition was predicted by features representing frames that select for pronouns and question words, and by content related to narratives and object play.

Disclosure of financial interests in scientific research is the centerpiece of the new conflict of interest regulations issued by the U.S. Public Health Service and the National Science Foundation that became effective October 1, 1995. Several scientific journals have also established financial disclosure requirements for contributors. This paper measures the frequency of selected financial interests held among authors of certain types of scientific publications and assesses disclosure practices of authors. We examined 1105 university authors (first and last cited) from (...) Massachusetts institutions whose 789 articles, published in 1992, appeared in 14 scientific and medical journals. (shrink)

On the analogy of the colloquial register in some modern languages, where narrative and argument may be punctuated by oaths and exclamations in order to maintain a high affective level and compel the hearer's attention, it is reasonable to postulate that Attic conversation also was punctuated by oaths, that this ingredient in comic language was drawn from life, and that the comparative frequency of ║ M M Δ in comedy is sufficiently explained thereby. There are obvious affinities between some (...) passages of comedy, relaxed conversation in Plato and Xenophon, and the forceful, man-to-man tone which Demosthenes sometimes adopts to such good effect . Compare, for instance, Ar. V. 133 f. στιν δ' νομα ⋮ τ μν γέροντι ⋮ Φιλοκλέων / να μ Δία, τ δ' υε κτλ., where the oath is a response to imagined incredulity, and X. Smp. 4.27 ατν δ σέ, η, γ εδον να μ τν πόλλω, τε κτλ. . It is also important that the commonest oaths fit, in most of their forms, the end of an iambic trimeter: μ τν Δία, ν Δία,ν τούς θεούς, μ τος θεούς. Add that in Aristophanic dialogue over half the iambic trimeters end with major pause, and half the remainder with minor pause, and we can see why Δ / established itself early as a distinctive comic pattern. Out of 105 examples of M M Δ cited from comedy in Section II above, 59 have the oath at verse-end. In the case of πάνυ, which was almost exclusively Attic and — to judge from its great rarity in tragedy — felt by Athenian poets to be prosaic, we lack evidence on its functions in the colloquial register; it may or may not have served as affective punctuation. In prose, we have to reckon with the fact that π Mπ and Mπ π constituted a genuine stylistic choice as far back as the evidence will take us, since the two earliest instances in prose are [X.] Ath. 2.3 πάνυ δι χρείαν and ibid. 3.5 πολλ τι πάνυ. The oath, as treated by the comic poets on the basis of colloquial usage, is bound to have served as a model for πάνυ, exerting an influence which pulled πάνυ to the end of the verse, but there was also a powerful metrical constraint. As a dibrach ending in a vowel which could not be elided or enter into crasis, πάνυ was especially appropriate for verse-end. That in itself was enough both to establish Mπ π as the dominant pattern in comedy and to promote Mπ … π. Out of the total of 104 examples of Mπ π in comedy, 93 have πάνυ at verse-end, which makes Mπ π / one of the hallmarks of comic style. Mπ … π does not occur in prose in association with any other feature identified as colloquial, but it should be noted that Aiskhines and Demosthenes are much fonder of Mπ π than other prose authors. In some cases one can see that the order Mπ π avoids a succession of short syllables or hiatus or both , but there are other cases in which it has the opposite effect . The possibility of comic influence on oratorical language cannot be dismissed out of hand. It is also possible that someone will find positive determinants which will explain all the cases of Mπ π in prose. σόδρα, which, like πάνυ, is peculiarly Attic, is metrically more tractable than πάνυ, since it can be elided; even so, out of the 80 comic examples of Mσ σ no less than 58 have σόδρα at verse-end, and of those 58 there are 22 at major pause, 8 at presumed major pause and 9 at minor pause. The comic treatment of σόδρα is thus comparable with the treatment of πάνυ, and Timokles 222.4 τηρεν…σόδρα is in fact the closest analogy we have to Ar. Pl. 234 f. χθομαι…πάνυ. δέ and γάρ are a different matter, and in some significant respects different from each other. Postponement of δέ is especially prominent in Aeschylus and then abundant in fourth-century comedy. It is much less common in Euripides , rare in Sophocles and Aristophanes , and virtually limited in prose to the categories which I labelled –. There is as yet no evidence to associate postponement of δέ with colloquial language; on the contrary, it seems to have begun as a feature of poetic language and to have been taken up and exploited by fourth-century comedy. If, in addition to being Aeschylean, it was colloquial in the fourth century, what happened to it afterwards? Except for such an isolated and inexplicable case as Diod. xx85.1 — in a military narrative — it is not a feature of the Koine at literary, documentary or subliterate level. Postponement of γάρ was no doubt encouraged by postponement of δέ, but it is not itself notably poetic ). One can see how it could possibly have developed in the spoken language of the fourth century, extending the function of γάρ as an explanatory particle in a way which makes it comparable with the English ‘you see’ in ‘He didn't dare pick it up. He hurt his back last year, you see’. For an extension of this kind we may compare the current extension of the English genitive affix in ‘Then the girl whose place she was taking's mother turned up’ and ‘The man that Christopher liked's Introduction is much better’. Moreover, postponed γάρ appears in a segment of conversation constructed in indirect speech by Theophrastus in Char. 8.9 τ πργμα βοσθαι γάρ . Again we must ask: what happened to it afterwards? A couple of cases in Theophrastus' botanical works could be a reflex of the influence of comedy on literary language at Athens. The influence was plainly short-lived, since it did not affect the Koine. It is not hard to see why serious poetry in the fifth century and earlier should have experimented occasionally with the postponement of δέ and γάρ: treatment of M M q as a valid alternative to M q M is metrically very convenient. No poet, however, could afford to use common words in a bizarre, un-Greek way merely to save himself time and trouble in constructing a verse. Linguistic innovation is normally analogical, proceeding by extension from a starting-point already there, and the most obvious starting-point for postponement of δέ and γάρ is constituted by my class . This consideration provides comic postponement with a pedigree, but does not deny it individuality. The remarkable scale and frequency with which comedy exploited a phenomenon which tragedy used with restraint and prose hardly at all gives comic postponement the right to be regarded as a quite distinctive artificial feature of comedy.

As Kennedy has shown (1973: 1149), the question of whether the shaman is a disturbed individual (neurotic, psychotic, or schizophrenic) or is on the contrary a gifted, balanced and perfectly well-adjusted person, constitutes one of the oldest of all anthropological debates. Indeed R. Hamayon and L. Delaby (1977: 8) have pointed out that “the tendency to attribute a pathological source to shamanism, and to reduce its manifestations to the manipulation of epileptic and psychotic episodes” appeared simultaneously with the publication of (...) the first studies on the subject, in the second half of the nineteenth century. Slavic authors in particular, most notably Bogoras (1910) and Czaplicka (1914), were anxious to establish a connection between shamanism and “Arctic hysteria.” Ohlmarks (1939), developing this theory, distinguished between Arctic and sub-Arctic shamanism in order to identify the degree of psychopathology in each shaman. Struck by the frequency of these types of phenomena in the Arctic regions, the authors believed that they had discovered their cause in race, heredity, and climate. (shrink)

Establishing phonologically robust lexical representations in a second language is challenging, and even more so for words containing phones in phonological contrasts that are not part of the native language. This study presents a series of additional analyses of lexical decision data assessing the phonolexical encoding of English /ε/ and /æ/ by German learners of English in order to examine the influence of lexical frequency, phonological neighborhood density and the acoustics of the particular vowels on learners’ ability to reject (...) nonwords differing from real words in the confusable L2 phones only. Results showed that both the lexical properties of the target items and the acoustics of the critical vowels affected nonword rejection, albeit differently for items with /æ/ → [ε] and /ε/ → [æ] mispronunciations: For the former, lower lexical frequencies and higher neighborhood densities led to more accurate performance. For the latter, it was only the acoustics of the vowel that had a significant impact on learners’ accuracy. This suggests that the encoding of /ε/ and /æ/ may not only be asymmetric in that /ε/ is generally more robustly represented in the lexicon than /æ/, as previously reported, but also in the way in which this encoding takes place. Mainly, the encoding of /æ/ appears to be more dependent on the characteristics of the L2 vocabulary and on one’s experience with the L2 than that of its more dominant counterpart. (shrink)

Introduction: Physical distancing under the coronavirus disease 2019 pandemic had a significant impact on lifestyles, including exercise routines. In this study, we examined the relationship between mental health and addictive behaviors, such as excessive exercise and the use of image and performance enhancing drugs across 12 sport disciplines.Materials and methods: A large cross-sectional sample of the adult population was surveyed. The mean age was 33.09. The number of male participants was 668. The use of IPEDs was assessed in conjunction with (...) psychometric measures such as the Exercise Addiction Inventory and the Appearance Anxiety Inventory. The participants were grouped into activity group and non-activity group according to the presence or absence of their exercise habits. The results were compared between these groups, as well as across sport disciplines, while taking into account the relationship between different psychological measures and IPEDs consumption.Results: The frequency of IPEDs use was higher among AG than NAG, although AG participants reported less history of addictions than NAG. The logistic regression analysis revealed that scores equal to or above cutoff points, in both the EAI and AAI, predicted the IPEDs use. Regarding the differences across the various sport disciplines, those who were involved in practicing Weight Lifting and Cross Fit were found to be more at risk of excessive exercising and more inclined to use a wide range of IPEDs.Conclusions: Although exercise could help to increase well-being and prevent addictions during the COVID-19 pandemic, our results show that those in the AG are particularly vulnerable to excessive IPEDs use. Sport disciplines associated with higher EAI and AAI scores have also shown a higher tendency to excessive IPEDs use. Furthermore, the factor of having above the cutoff scores in EAI or AAI in each sport could indicate larger IPEDs consumption regardless of the discipline. In light of the current findings, it is necessary to better define the “non-excessive” levels of exercise in various sport disciplines and an adequate intake of IPEDs to ensure the safety and well-being of people during a pandemic.

The regular increase in the proportion of resolved feet in the iambic trimeters of Euripides' later plays was first commented upon in 1807 by J. Gottfried Hermann, who therefrom deduced the principle that the date of any play of Euripides could be directly determined from the frequency of its resolutions. This criterion he restated in several of his works in the following years, and when Elmsley objected that it was of uncertain value on account of the small number of (...) plays of certain date by which it might be verified, he replied with a strong defence of his case: he did not, however, develop his principle in detail or give figures in its support. The first scholar to publish the totals of trisyllabic feet in each play was Zirndorfer: relying largely on these, he produced a chronology of Euripides' dramatic composition in several respects superior to any predecessor's. His conclusions were questioned by C. F. W. Müller, who, while accepting Hermann's thesis as being in general correct, doubted its reliability for determining the exact period of a tragedy's composition. Consequently, although he gave the totals of trisyllabic feet en passant, Müller made no attempt to suggest dates. At almost the same time as Müller's treatise appeared, J. Rumpel published an article giving a full and detailed list of references to all trisyllabic feet in Euripides: from this evidence he divided the dramas into four age-groups, but did not go so far as to assign specific dates.

Injuries in professional soccer are a significant concern for teams, and they are caused amongst others by high training load. This cohort study describes the relationship between workload parameters and the occurrence of non-contact injuries, during weeks with high and low workload in professional soccer players throughout the season. Twenty-one professional soccer players aged 28.3 ± 3.9 yrs. who competed in the Iranian Persian Gulf Pro League participated in this 48-week study. The external load was monitored using global positioning system (...) and the type of injury was documented daily by the team's medical staff. Odds ratio and relative risk were calculated for non-contact injuries for high- and low-load weeks according to acute, chronic, acute to chronic workload ratio, and AW variation values. By using Poisson distribution, the interval between previous and new injuries were estimated. Overall, 12 non-contact injuries occurred during high load and 9 during low load weeks. Based on the variables ACWR and Δ-AW, there was a significantly increased risk of sustaining non-contact injuries during high-load weeks for ACWR, and Δ-AW. Finally, the expected time between injuries was significantly shorter in high load weeks for ACWR [1.25 vs. 3.33, rate ratio time ] and Δ-AW respectively, compared to low load weeks. The risk of sustaining injuries was significantly larger during high workload weeks for ACWR, and Δ-AW compared with low workload weeks. The observed high OR in high load weeks indicate that there is a significant relationship between workload and occurrence of non-contact injuries. The predicted time to new injuries is shorter in high load weeks compared to low load weeks. Therefore, the frequency of injuries is higher during high load weeks for ACWR and Δ-AW. ACWR and Δ-AW appear to be good indicators for estimating the injury risk, and the time interval between injuries. (shrink)

Resumen: Este estudio examina la frecuencia de colocaciones gramaticales verbo + preposición en aprendientes anglófonos de Español como Lengua Extranjera de nivel A2 y B1 bajo el modelo de Análisis Contrastivo de la Interlengua. Para ello se implementa una tipología colocacional sustentada en un criterio de fijación intermedia de estas unidades. Los resultados muestran mayor frecuencia en el nivel B1, pero no en la variedad de unidades, y un mayor número de usos correctos que en A2. Respecto de las diferencias (...) encontradas según el patrón sintáctico-semántico, las variables competencia, complejidad del patrón y temáticas aparecen como factores importantes para explicarlas en el contexto del corpus de aprendientes examinado. Este trabajo aporta al estudio de las ColGram v+p, y de otros tipos en ELE.: This study examines the frequency of grammatical collocations verb + preposition in L1-English learners of Spanish as a Foreign Language of levels A2 and B1 under the model of Interlanguage Contrastive Analysis. To this end, a collocational typology based on a criterion of intermediate fixedness was implemented. The results show higher frequency in level B1, but not in the variety of the units, and a greater number of correct uses than in A2. Regarding found differences according to syntactic and semantic pattern, the variables of competence, pattern complexity and theme appear to play an important role in their explanation in the context of the learners’ corpus examined. This work contributes to the study of GramCol v+p and other types in SFL. (shrink)

In this paper, we propose a 3-dimensional self-organizing memory and describe its application to knowledge extraction from natural language. First, the proposed system extracts a relation between words by JUMAN and KNP, and stores it in short-term memory. In the short-term memory, the relations are attenuated with the passage of processing. However, the relations with high frequency of appearance are stored in the long-term memory without attenuation. The relations in the long-term memory are placed to the proposed 3-dimensional (...) self-organizing memory. We used a new learning algorithm called ``Potential Firing'' in the learning phase. In the recall phase, the proposed system recalls relational knowledge from the learned knowledge based on the input sentence. We used a new recall algorithm called ``Waterfall Recall'' in the recall phase. We added a function to respond to questions in natural language with ``yes/no'' in order to confirm the validity of proposed system by evaluating the quantity of correct answers. (shrink)

Previous studies have reported that general or photo-specific social media use was associated with women’s body dissatisfaction and body image disturbance. The current study replicated and expanded upon these findings by identifying the positive association between social media influencer viewing and intentions to change appearance. This study surveyed a sample of 7,015 adult female TikTok users in China regarding their social media influencer viewing frequency, self-objectification, social comparison tendencies when watching short videos, intentions to change appearance, and (...) demographics. The results showed that female TikTok users’ self-objectification mediated the association between their influencer viewing frequency and their intentions to change appearance. Furthermore, social comparison tendencies moderated the association between influencer viewing and intentions to change appearance in that the proposed association was stronger for female TikTok users who had lower social comparison tendencies when watching short videos, compared to female TikTok users who had higher social comparison tendencies. The counter-intuitive finding on social comparison tendencies indicated that women who have higher social comparison tendencies may be more aware of the negative influences and adjust their expectations. The observed association between social media influencer viewing and intentions to change appearance was statistically significant but trivial in terms of effect size. Although the result could warn policymakers and practitioners to design media and health literacy campaigns to cultivate body positivity, caution should be exercised when evaluating the practical implications.

In the last decades, scientific developments are largely discussed and debated mainly at the media level. Based on the agenda setting model, the importance of a certain theme is given by the frequency of its appearances in mass-media. Within this context, this paper focuses on the issue of stem cells and its media coverage in Romania. Using content analysis of the most read national newspapers, the research aims to emphasize two relevant aspects: the stem cells issue is only partly (...) visible in the written media and the debate between ethics and science is rather non-existent.

This study examines Australian tax agents' perceptions of the ethical environment in which they practice, within the context of an income tax system based on self-assessment principles. The research identifies and ranks an inventory of ethical issues in terms of perceived frequency of occurrence and importance to Western Australian tax agents. In addition, the extent and influence of ethical concerns in the profession are evaluated.The study has determined that the most frequently cited ethical issue is the failure to make (...) reasonable enquiries where information or documentation provided by a client appears to be inaccurate or incomplete. The most important ethical problem is a failure to ensure confidentiality with regard to privileged client information. When the frequency of occurrence and importance means are compared, inadequate technical competence, failure to make reasonable enquiries/conduct research, continuing to act for a client where there is incorrect information, and conflicts in distinguishing between tax planning and tax avoidance emerge as the high frequency/high importance issues. Although acknowledging the potential for unethical actions in tax practice, Western Australian tax agents consider that they carry out their professional activities within an ethical environment.

The COVID-19 pandemic poses a major challenge to policy makers on how to encourage compliance to social distancing and personal protection rules. This paper compares the effectiveness of two policies that aim to increase the frequency of responsible health behavior using smartphone-tracking applications. The first involves enhanced alert capabilities, which remove social externalities and protect the users from others’ reckless behavior. The second adds a rule enforcement mechanism that reduces the users’ benefit from reckless behavior. Both strategies should be (...) effective if agents are expected-value maximizers, risk averse, and behave in accordance with cumulative prospect theory or in accordance with the Cognitive Hierarchy model. A multi-player trust-game experiment was designed to compare the effectiveness of the two policies. The results reveal a substantial advantage to the enforcement application, even one with occasional misses. The enhanced-alert strategy was completely ineffective. The findings align with the small samples hypothesis, suggesting that decision makers tend to select the options that lead to the best payoff in a small sample of similar past experiences. In the current context, the tendency to rely on a small sample appears to be more consequential than other deviations from rational choice. (shrink)

Some of the most imaginative analyses in contemporary science have been fostered by the paradox of irreversibility. Rendered as a question the paradox reads: How can the anisotropic macrophysical behavior of a system of molecules be reconciled with the underlying reversible molecular model? Attempts to resolve and dissolve the paradox have appealed to large numbers of particles, jammed correlations, unseen perturbations, hidden variables or constraints, uncertainty principles, averaging procedures (e.g., coarse graining and time smoothing), stochastic flaws, cosmological origins, etc. While (...) acknowledging these efforts as important articulations of basic ideas of statistical mechanics, we question their relevance to irreversibility as it occurs in nature. It seems to us that once the emergence of the phenomenon of equilibrium is understood in terms of molecular dynamics, the macroscopic appearance of irreversibility can also be understood in terms of the frequency of forced withdrawals from young equilibria. We believe that the paradox of irreversibility can be resolved in a simple, logically clear, and aesthetically pleasing manner. (shrink)
