Often Overlooked Aspects of Sound Symbolism: The Influence of Participants' Characteristics on Size Ratings.

Sound symbolism is a non-arbitrary mapping between phonetic properties and meanings. The existence and nature of sound symbolism have long been the subject of empirical research. It is rarely recognized, however, that participants' intrinsic characteristics (e.g., age, gender, language knowledge), in addition to the commonly studied phonetic features, may also influence size ratings. Our study aims to empirically investigate the impact of participant-specific characteristics on size ratings: It also aims to examine whether these characteristics have a direct impact when considering the impact of phonetic features or they rather modify the effects of phonetic features. The current research reports a novel analysis of a previously published dataset with new research questions and previously unused (participant-specific) data. We show that (a) the participants' characteristics did not affect overall size ratings; however, (b) in some cases, they modify (intensify or weaken but do not reverse) the effect of phonetic features on size ratings. Our results emphasize a more comprehensive treatment of sound symbolism, one that considers not only phonetic but also non-phonetic factors in sound symbolism research.

Topic modelling online depression forums: beyond narratives of self-objectification and self-blaming.

BACKGROUND: Depression raises a double challenge: besides the negative mood and the intrusive thoughts, the relation to the self also becomes difficult. Online forums are analysed as communicative platforms enabling the interactive reconstruction of the self. AIMS: The discourses of online depression forums are explored. Firstly, narrative patterns are identified according to their thematic focus (e.g. dysfunctional body, challenges of intimacy) and discursive logic (e.g. information exchange, support). Secondly, narratives are analysed in order to describe various ways of grounding a depressed self. METHODS: ∼70.000 depression-related posts from the biggest English-speaking online forums (e.g. www.reddit.com/r/depression, www.healthunlocked.com) were analysed. Quantitative (LDA topic modelling) and qualitative (deep reading) approaches were used simultaneously to determine the optimal number of topics and their interpretation. RESULTS: 13 topics were identified and interpreted according to their content and communicative function. Based on the inter-topic distances four clusters were identified (medicalized, intimacy-oriented, critical and uninhabitable self-narratives). CONCLUSIONS: The clusters of the 13 topics highlight various ways of narrating depression and the depressed self. Based on a comparison with a systematic review of mental illness recovery narratives, depression forums cover most narrative genres and emotional tones, thus create a unique opportunity for integrating the depressing experiences in the self.

A scoping review on the use of natural language processing in research on political polarization: trends and research prospects.

As part of the "text-as-data" movement, Natural Language Processing (NLP) provides a computational way to examine political polarization. We conducted a methodological scoping review of studies published since 2010 (n = 154) to clarify how NLP research has conceptualized and measured political polarization, and to characterize the degree of integration of the two different research paradigms that meet in this research area. We identified biases toward US context (59%), Twitter data (43%) and machine learning approach (33%). Research covers different layers of the political public sphere (politicians, experts, media, or the lay public), however, very few studies involved more than one layer. Results indicate that only a few studies made use of domain knowledge and a high proportion of the studies were not interdisciplinary. Those studies that made efforts to interpret the results demonstrated that the characteristics of political texts depend not only on the political position of their authors, but also on other often-overlooked factors. Ignoring these factors may lead to overly optimistic performance measures. Also, spurious results may be obtained when causal relations are inferred from textual data. Our paper provides arguments for the integration of explanatory and predictive modeling paradigms, and for a more interdisciplinary approach to polarization research.

The asymmetries of the biopsychosocial model of depression in lay discourses - Topic modelling online depression forums.

BACKGROUND: One of the most comprehensive approaches to depression is the biopsychosocial model. From this wider perspective, social sciences have criticized the reductionist biomedical discourse, which has been dominating expert discourses for a long time. As these discourses determine the horizon of attributions and interventions, their lay interpretation plays a central role in the coping with depression. METHODS: In order to map these patterns, online depression forums are analyzed with natural language processing methods, where computational tools are complemented with a qualitative approach. Latent Dirichlet Allocation topic model of depression-related posts from the most popular English-speaking online health discussion forums (N = ~70 000) reveals the monolog (attributions and self-disclosures) and interactive (consultations and quasi-therapeutic interactions) patterns. RESULTS: Following the evaluation of various models 18 topics were differentiated: attributions referring to health, family, partnership and work issues; self-disclosures referring to contemplations, introducing the experience of suffering and well-being, along with diaries of everyday activities and hardships; consultations about psychotherapies, classifications, drugs and the experience; and quasi-therapeutic interactions relying on unconditional positive regards, recovery helpers experience or spirituality. These topics were evaluated from the perspective of the biopsychosocial model: the weight of each dimension was measured along with the discursive function. CONCLUSIONS: Biomedical discourse is underrepresented in lay discussions, while psychological discourse plays an overall dominant role. Even if actors are initially aware of the social mechanisms contributing to depression, they neglect these factors when it comes to considering the countermeasures.

A novel approach to the characterization of old wheat (Triticum aestivum L.) varieties by complex rheological analysis.

BACKGROUND: Lines of the internationally recognized old Hungarian Bánkúti 1201 variety are important genetic resources for breeding programmes. Their protein composition and gluten dependent technological traits have been comprehensively studied, however, little information is available about their carbohydrate dependent viscous properties. The aim of this work was to obtain comprehensive rheological characterization of all sublines of Bánkúti 1201 maintained at Martonvásár and to investigate their variability if the carbohydrate dependent viscous behaviour was also included in the analyses. RESULTS: The majority of the lines reflected the famously good mixing quality of Bánkúti, however, much higher diversity of pasting behaviour was detected. Cluster analysis of the Mixolab data was performed resulting in four sample groups. Since several lines of similar mixing properties had significantly different pasting characteristics, it was assumed that classification was mainly based on the viscous properties. From each cluster two to three representative samples were selected for wider examination using conventional testing methods. These results also supported the higher variability of pasting behaviour of the lines, which can be critical for end product quality. The members of the second cluster can be highlighted due to their waxy wheat like behaviour. CONCLUSIONS: Possible reasons for the great variability of pasting behaviour could be the compositional and structural differences of starch and other carbohydrates (e.g. arabinoxylans). Complex rheological characterization and study of molecular background can provide information about important traits from the point of view of technology and product development, which are unknown in the case of old wheat varieties and landraces. © 2020 Society of Chemical Industry.

Whose Norms, Whose Prejudice? The Dynamics of Perceived Group Norms and Prejudice in New Secondary School Classes.

Ethnic prejudice can lead to exclusion and hinder social integration. Prejudices are formed throughout socialization, and social norms inform individuals about the acceptability of prejudice against certain outgroups. Adolescence is a crucial period for the development of intergroup attitudes, and young people are especially prone to follow the norms they perceive in their reference groups. At the same time, the effect of perceived norms on prejudice in school classes has been rarely studied. In Hungary, where prejudice against the Roma is widespread and there is no clear social norm proscribing prejudiced manifestations, this topic is especially relevant. In the present paper, based on multi-level analyses of panel data from Hungarian ninth-graders, we find that adolescents adjust their attitudes to those they perceive to be dominant among their classmates and that classmates serve as more important reference groups than teachers do. More contact with Roma is found to be associated with less prejudice against them. Looking at school classes, we find that at the beginning of the school year, many students underestimate the rejection of prejudiced expressions in their classes. By the end of the year, many students are found to adjust their own attitudes to the falsely perceived class norm. Based on our findings, we argue that school classes should be treated as important normative contexts for the socialization of intergroup attitudes and should receive special attention from both scholars and practitioners working in the fields of prejudice research and reduction. Furthermore, we suggest that teachers can most successfully hinder prejudices by working on a common, visible, shared class norm rather than "teaching" students that prejudices are not acceptable.

Optimization of Arabinoxylan Isolation from Rye Bran by Adapting Extraction Solvent and Use of Enzymes.

Physicochemical and functional properties of arabinoxylans (AXs) can be significantly influenced by their isolation method. Finding balanced process conditions that allow optimal extraction yields while preserving AXs functionality is a challenge. The aim of this study was to determine the effect of different chemical solvents with neutral and alkaline pH on the intrinsic properties and extraction yield of AXs isolated from rye bran. Additionally, the application of xylanases and other cell wall degrading enzymes (Pentopan Mono BG, Deltazym XL-VR, Viscoflow BG) to solubilize bound AXs was investigated. Results show that the use of Ca(OH)2 for isolation was superior to water and Na2 CO3 , as it selectively solubilized AXs and delivered isolates with a purity of up to 43.92% AX and a moderate ferulic acid (FA) content (209.35 ± 16.79 mg FA/100 g AX). Application of xylanases was further able to duplicate these achieved AX yields (7.50 to 9.85g AX/100 g bran). Additionally, isolates displayed highest ferulic acid contents (445.18 to 616.71 mg FA/100 g AX) and lowest impurities in comparison to chemical extracted AXs. Rheological characterization of the isolates showed a pronounced shear thinning behavior which fitted well to the power-law model (R2 > 0.989). Differences in pseudoplasticity of the isolates suggested that structural and chemical properties might have been responsible for this behavior.

Mismatch response (MMR) in neonates: Beyond refractoriness.

In the adult auditory system, deviant detection and updating the representation of the environment is reflected by the event-related potential (ERP) component termed the mismatch negativity (MMN). MMN is elicited when a rare-pitch deviant stimulus is presented amongst frequent standard pitch stimuli. The same stimuli also elicit a similar discriminative ERP component in sleeping newborn infants (termed the mismatch response: MMR). Both the MMN and the MMR can be confounded by responses generated by differential refractoriness of frequency-selective neural populations. Employing a stimulus paradigm designed to minimize this confounding effect, newborns were presented with sequences of pure tones under two conditions: In the oddball block, rare deviant tones (500Hz; 10%) were delivered amongst frequent standards (700Hz; 90%). In the control block, a comparison tone (500Hz) was presented with the same probability as the deviant (10%) along with the four contextual tones (700Hz, 980Hz, 1372Hz, 1920.8Hz; 22.5% each). The significant difference found between the response elicited by the deviant and the comparison tone showed that the response elicited by the deviant in the oddball sequences cannot be fully explained by frequency-specific refractoriness of the neural generators. This shows that neonates process sounds in a context-dependent manner as well as strengthens the correspondence between the adult MMN and the infant MMR.

Processing of Horizontal Sound Localization Cues in Newborn Infants.

OBJECTIVES: By measuring event-related brain potentials (ERPs), the authors tested the sensitivity of the newborn auditory cortex to sound lateralization and to the most common cues of horizontal sound localization. DESIGN: Sixty-eight healthy full-term newborn infants were presented with auditory oddball sequences composed of frequent and rare noise segments in four experimental conditions. The authors tested in them the detection of deviations in the primary cues of sound lateralization (interaural time and level difference) and in actual sound source location (free-field and monaural sound presentation). ERP correlates of deviance detection were measured in two time windows. RESULTS: Deviations in both primary sound localization cues and the ear of stimulation elicited a significant ERP difference in the early (90 to 140 msec) time window. Deviance in actual sound source location (the free-field condition) elicited a significant response in the late (290 to 340 msec) time window. CONCLUSIONS: The early differential response may indicate the detection of a change in the respective auditory features. The authors suggest that the late differential response, which was only elicited by actual sound source location deviation, reflects the detection of location deviance integrating the various cues of sound source location. Although the results suggest that all of the tested binaural cues are processed by the neonatal auditory cortex, utilizing the cues for locating sound sources of these cues may require maturation and learning.

Predictive processing of pitch trends in newborn infants.

The notion of predictive sound processing suggests that the auditory system prepares for upcoming sounds once it has detected regular features within a sequence. Here we investigated whether predictive processes are operating at birth in the human auditory system. Event-related potentials (ERP) were recorded from healthy newborns to occasional ascending pitch steps occurring in the 2nd or the 5th position within trains of tones with otherwise monotonously descending pitch. If the trains were processed in a predictive manner only deviant pitch steps occurring in the later train position would elicit the discriminative mismatch response (MMR). Deviants delivered in the 5th but not in the 2nd position of the tone trains elicited a significant MMR response. These results suggest that newborns represent pitch trends within sound sequences and they process them in a predictive manner. This article is part of a Special Issue entitled SI: Prediction and Attention.

Newborn infants detect cues of concurrent sound segregation.

Separating concurrent sounds is fundamental for a veridical perception of one's auditory surroundings. Sound components that are harmonically related and start at the same time are usually grouped into a common perceptual object, whereas components that are not in harmonic relation or have different onset times are more likely to be perceived in terms of separate objects. Here we tested whether neonates are able to pick up the cues supporting this sound organization principle. We presented newborn infants with a series of complex tones with their harmonics in tune (creating the percept of a unitary sound object) and with manipulated variants, which gave the impression of two concurrently active sound sources. The manipulated variant had either one mistuned partial (single-cue condition) or the onset of this mistuned partial was also delayed (double-cue condition). Tuned and manipulated sounds were presented in random order with equal probabilities. Recording the neonates' electroencephalographic responses allowed us to evaluate their processing of the sounds. Results show that, in both conditions, mistuned sounds elicited a negative displacement of the event-related potential (ERP) relative to tuned sounds from 360 to 400 ms after sound onset. The mistuning-related ERP component resembles the object-related negativity (ORN) component in adults, which is associated with concurrent sound segregation. Delayed onset additionally led to a negative displacement from 160 to 200 ms, which was probably more related to the physical parameters of the sounds than to their perceptual segregation. The elicitation of an ORN-like response in newborn infants suggests that neonates possess the basic capabilities of segregating concurrent sounds by detecting inharmonic relations between the co-occurring sounds.

Mapping the Nottingham Health Profile onto the Preference-Based EuroQol-5D Instrument for Patients with Diabetes.

OBJECTIVE: The aim of this study was to derive a function that can map the Nottingham Health Profile (NHP) questionnaire onto a utility measure, the EuroQol five-dimensional (EQ-5D) questionnaire index, for diabetic patients. METHODS: A cross-sectional study was performed on diabetic patients in Hungary with different complications in which quality of life was measured by using both the NHP questionnaire and the EQ-5D questionnaire. Ordinary stepwise-backward least-squares regression was used to develop a mapping function. Adjusted R2, Akaike's information criterion, and root mean square error were used to assess the performance of the model. The robustness of the models was tested using 10-fold cross-validation and bootstrapping. RESULTS: The best-fitting models were those that contained all the NHP statements as predictors and a stepwise reduced version that contained only 19 statements. The latter model, however, showed considerable variability in the selection of predictors. The adjusted R2 of the former model was 0.68, the root mean square error was 174, and the Akaike's information criterion was -559.9. CONCLUSIONS: The expected value of the EQ-5D questionnaire can be reasonably predicted on the basis of results of the NHP in patients with diabetes mellitus. The mapping function of the NHP onto the EQ-5D questionnaire is capable of estimating the expected EQ-5D questionnaire utility values in a group of patients with diabetes. The function's applicability for individual-level predictions, however, is limited. Further research is needed to find out whether mapping functions developed in Central-Eastern European countries are transferable to Western European countries.

Context effects on processing widely deviant sounds in newborn infants.

Detecting and orienting toward sounds carrying new information is a crucial feature of the human brain that supports adaptation to the environment. Rare, acoustically widely deviant sounds presented amongst frequent tones elicit large event-related brain potentials (ERPs) in neonates. Here we tested whether these discriminative ERP responses reflect only the activation of fresh afferent neuronal populations (i.e., neuronal circuits not affected by the tones) or they also index the processing of contextual mismatch between the rare and the frequent sounds. In two separate experiments, we presented sleeping newborns with 150 different environmental sounds and the same number of white noise bursts. Both sounds served either as deviants in an oddball paradigm with the frequent standard stimulus a tone (Novel/Noise deviant), or as the standard stimulus with the tone as deviant (Novel/Noise standard), or they were delivered alone with the same timing as the deviants in the oddball condition (Novel/Noise alone). Whereas the ERP responses to noise-deviants elicited similar responses as the same sound presented alone, the responses elicited by environmental sounds in the corresponding conditions morphologically differed from each other. Thus whereas the ERP response to the noise sounds can be explained by the different refractory state of stimulus-specific neuronal populations, the ERP response to environmental sounds indicated context-sensitive processing. These results provide evidence for an innate tendency of context-dependent auditory processing as well as a basis for the different developmental trajectories of processing acoustical deviance and contextual novelty.

[Dietary survey in Hungary, 2003-2004. Micronutrients: vitamins]. / Táplálkozási vizsgálat Magyarországon, 2003-2004. Mikrotápanyagok: vitaminok.

The 3rd Hungarian National Nutritional Survey was carried out as a part of the National Population Health Study and the data collection was done in November/December of 2003. The survey comprised a sample of adults above 19 year of age, the dietary questionnaires of 1179 people could be evaluated. The results of energy and macro-nutrient intake were published in 2005, and the results of the mineral intake in 2007, in the Hungarian Medical Journal. This paper focuses on the intake of vitamins. For the evaluation of the results authors used the data of the two previous national surveys, data of some dietary studies of other countries, and the home and international intake recommendations. In respect of the data found in the present survey, it is a favourable trend that the intake of vitamins retinol equivalent, B1 , B6 and B12 , and niacin, as well as biotin was sufficient both in case of men and women, together with adequate vitamin E intake for men. However the intake of vitamin B2 , C, D, together with pantothenic acid and folic acid of both men and women did not meet the criteria of the Hungarian recommendations, besides the vitamin E intake of women was insufficient as well. In Hungary the intake of vitamin D, biotin, folic acid and pantothenic acid was measured at first at this National Dietary Survey. The authors vigorously stress the importance of the varied and healthy nutrition in the adequate vitamin supply of the population.

[Hungarian national dietary survey, 2003-2004. Micronutrients: mineral salts]. / Táplálkozási vizsgálat Magyarországon, 2003-2004. Mikro-tápanyagok: ásványi sók.

In the course of the 3rd national nutritional survey data were collected in 2003, and the paper on the energy and nutrition intake of a sample group consisting of 1179 people all aged above 19, was published in the Hungarian Medical Journal (Vol. 146, No. 34, 2005). The present paper focuses on one group of micronutrients, namely the minerals' intake. The authors evaluated the results mainly in comparison with the data of the two previous Hungarian national surveys, and the international and national recommendations. The average magnesium intake was considered adequate in both sexes, while iron, zinc and copper intakes also met the recommended level in men. On the other hand, the insufficient calcium and the excessive phosphorus intakes, as well as the disproportionate calcium-phosphorus ratio in both sexes are unfavourable facts. The adverse results include insufficient iron, zinc and copper intake in women and the excessive sodium intake in both sexes, as well. The authors emphasize the importance of spreading the principles of healthy nutrition as well as co-operating with the food industry in order to prevent the occurrence of mineral nutrients deficiency.

A comparative health survey of the inhabitants of Roma settlements in Hungary.

OBJECTIVES: We compared the health of people living in Roma settlements with that of the general population in Hungary. METHODS: We performed comparative health interview surveys in 2003 to 2004 in representative samples of the Hungarian population and inhabitants of Roma settlements. RESULTS: In persons older than 44 years, 10% more of those living in Roma settlements reported their health as bad or very bad than did those in the lowest income quartile of the general population. Of those who used any health services, 35% of the Roma inhabitants and 4.4% of the general population experienced some discrimination. In Roma settlements, the proportion of persons who thought that they could do much for their own health was 13% to 15% lower, and heavy smoking and unhealthy diet were 1.5 to 3 times more prevalent, than in the lowest income quartile of the general population. CONCLUSIONS: People living in Roma settlements experience severe social exclusion, which profoundly affects their health. Besides tackling the socioeconomic roots of the poor health of Roma people, specific public health interventions, including health education and health promotion programs, are needed.

[Dietary survey in Hungary, 2003-2004]. / Táplálkozási vizsgálat Magyarországon, 2003-2004.

The third Hungarian national dietary survey was conducted in 2003-2004. This publication describes the first part of the energy and nutrient intake findings in a sample consisting of a population of 1179 persons over 19 years of age (energy and macro nutrients). Energy and nutrient intake values were calculated based on 3 x 24- hour dietary records filled out by the subjects themselves. The authors evaluated the results in light of the two previous dietary surveys in Hungary and the Hungarian and international reference intake data. The total fat intake found in this survey lower than the previous data marks a favourable development, just as the higher unsaturated fatty acid and lower saturated fatty acid energy percent, and furthermore the lower cholesterol intake level. The favourable developments include further a polyunsaturated/saturated fatty acid ratio considerably higher than that obtained earlier (the values conforming to the international reference data), a higher carbohydrate energy percentage, as well as lower added sugar energy percentage, this latter being in the recommended range. The overweight ratio in men was 58.9%, while the female value was 49.5%, not much different from the previous survey data.

[Health-related quality of life of the Hungarian population]. / A magyar lakosság egészségi állapothoz kapcsolódó életminósége.

AIMS: The objective of this study was to measure the health-related quality of life of the Hungarian general population. The quality of life survey was part of the National Health Survey (Országos Lakossági Egészségfelmérés, OLEF) conducted in year 2000 on a representative sample of 5503 members of the general population. RESULTS: Showed that, among the five health-related quality of life dimensions measured by the EQ-5D questionnaire, pain/discomfort had the highest (38%) prevalence. More than 60% of the population over 60 years of age suffer from pain or discomfort. In international comparison, anxiety/depression also had high prevalence in Hungary when compared to other developed countries. More than third of the Hungarian adult population today is depressed or suffer from anxiety. The analysis also highlighted the important association between socio-economic factors and health-related quality of life. According to the applied model, older age, being female, lower education, and lower income are the main determinants of worse health-related quality of life. When quality of life is measured on a 0-100 scale, each additional life year is associated with a decrease of 0.4 units of quality of life, being female is associated with 3 units lower quality of life. Each 10,000 Ft increase in mean household income improves quality of life with 0.5 unit. People with higher education have 5 units higher quality of life than those below medium level education. CONCLUSION: Findings of this study provide important baseline data for future burden of illness, health economic, and health policy analyses in Hungary.
