Published: February 2022

Το άρθρο εξετάζει την πολυτροπικότητα αλληλεπιδράσεων με και διά των κουκλών στο πλαίσιο ενός εκπαιδευτικού προγράμματος για παιδιά με προσφυγική εμπειρία. Το πρόγραμμα, που έλαβε χώρα σε τάξη ΔΥΕΠ στον Βόλο, είχε ως στόχο τη διευκόλυνση της μετάβασης των παιδιών στο σχολείο με δημιουργικό και παιγνιώδη τρόπο (Almond, 2005˙ Calvert, & Sheen, 2015). Μία ποικιλία δράσεων με κούκλες πλαισιώνει την εκπαιδευτική διαδικασία και συμβάλλει στην επικοινωνία μεταξύ των παιδιών και των εμψυχωτριών. Η εργασία μελετά την επικοινωνιακή συμπεριφορά των παιδιών με και διά των κουκλών και αναγνωρίζει τους γλωσσικούς και ενσώματους πόρους με τους οποίους τα παιδιά δημιουργούν νόημα και διαμεσολαβούν τη συμμετοχή τους στο εκπαιδευτικό δρώμενο. Αντλώντας από τη θεωρία της πολυτροπικότητας (Νοrris, 2004), αναλύονται βιντεοσκοπημένες αλληλεπιδράσεις και προτείνεται μια δομημένη κλίμακα με τους ποικίλους σημειωτικούς πόρους που συνεργούν κατά την επικοινωνία. Ενδεικτικό επικοινωνιακό επεισόδιο επιχειρηματολογεί για τη λειτουργικότητά τους. Όπως προκύπτει από την παρούσα έρευνα, σε επίπεδο μεθοδολογίας η πολυτροπική ανάλυση επιτρέπει να αποτιμήσουμε τους διαφορετικούς επικοινωνιακούς τρόπους που χρησιμοποιούν οι συμμετέχοντες/ουσες όταν μοιράζονται λίγους κοινούς γλωσσικούς πόρους. Επίσης, τα ευρήματα της έρευνας καταδεικνύουν το θετικό ρόλο της κούκλας στην εμπλοκή του παιδιού στο επικοινωνιακό γεγονός, την υπόδειξη προθέσεων και την ανάδειξη στοιχείων της ταυτότητάς του.

HighlightsAnimal agriculture intensification has greatly affected nutrient cycling and circularity in food production systems.Various nutrient balance methods are developed to improve nutrient management at various spatial scales.Balance-derived thresholds for action are identified using real-life examples in dairy production.Outreach and knowledge exchange are critical for development, adoption, and improvement of nutrient balance methods.Abstract. Animal agriculture is a major consumer and generator of both macro- and micronutrients. Intensification and regional concentration of animal production, due to economic and logistical advantages, have altered nutrient fluxes in agriculture systems, causing increased stock of nutrients in soils and, consequently, their emission to air and transport to surface water and groundwater. Established nutrient and manure planning frameworks, while effective in addressing nutrient point sources and using manure to enhance fertility and soil quality, have not been wholly successful in addressing farm- and region-scale challenges with nutrient concentrations. This review article addresses nutrient management issues associated with modern animal agriculture by advancing the use of nutrient budgets and balances. This is accomplished by establishing core concepts for nutrient budgets and balances as they apply to animal agriculture. Relevant spatial scales for these budgets are reviewed, including field, whole-farm, and watershed scales, along with proposed methodologies and data sources for each. This study also identifies existing region- and commodity-specific metrics (when available) for use as thresholds for corrective action toward more balanced nutrient budgets. Finally, recommendations for the community of practitioners, researchers, and educators are provided to address nutrient imbalance in animal agriculture systems. At farm and region scale, nutrient balance investments will be needed to strengthen accounting methodologies, develop appropriate data sources for measurements, identify thresholds for action, and apply the methods in appropriate settings and decisions. Data availability and uncertainty are recognized as key limitations facing wider adoption of these concepts, particularly considering data ownership and privacy concerns. The lack of transparent datasets that capture current animal production practices and their impact on manure composition and nutrient cycling is a gap facing these methodologies. The lack of engagement by practitioners and producers in the development phase of such tools greatly affects their adoption and utility. The need for continued engagement in establishing accepted methodologies, training, data collection, and education are crucial to establish farm- and region-scale methods and measure their value to nutrient planning over time. Keywords: Farm scale, Livestock, Manure nutrients, Nutrient budget, Poultry, Regional scale.
Parámetros temporales de las oclusivas sordas en un hablante con afasia de Broca y apraxia del habla: estudio de caso
Authors: Martínez Bielsa Paula 
Published: February 2022

Este trabajo pretende analizar los parámetros temporales de las consonantes oclusivas sordas [p, t, k] en el habla espontánea de un hablante con afasia de Broca y apraxia del habla en tres momentos diferentes de su enfermedad, a fin de determinar el nivel de deterioro respecto a su producción sin patología, así como su evolución tras veintidós meses de terapia logopédica. Las principales variables estudiadas han sido la duración consonántica, de la fase de silencio y del VOT. Los resultados estadísticos indican que los parámetros temporales presentan valores mayores a los observados en hablantes sin patología y que estos van en descenso a lo largo de la rehabilitación, especialmente para la realización bilabial. Las variaciones en la duración dependen, fundamentalmente, del punto de articulación y de los procesos de mantenimiento o debilitamiento de la sonoridad. Además, se ha advertido que las principales mejoras se han producido durante el periodo de recuperación espontánea y que las características acústicas de la realización bilabial se diferencian de las de las consonantes dental y velar, siendo la primera la que presenta los valores de duración más altos, así como los patrones de mejora más significativos.

Published: February 2022

BACKGROUND: Obesity and overweight are more common, especially among women of reproductive age. Therefore, the approach to maternal obesity requires a multidisciplinary approach, especially health professionals working in primary care preventive health services.AIM: The aim of the study is to determine the effect of maternal obesity on maternal and newborn health in Al Khansaa Teaching Hospial, City of Mosul, Iraq.MATERIALS AND METHODS: The study, which was planned as à case-control study, was conducted in the Al Khansa Teaching Hospital City of Mosul, Iraq.The inclusion criteria included women in postnatal period in the same Hospital, speaking and understanding Arabic, knowing her pre-pregnancy weight, not having any chronic disease (diabetes, hypertension, trioid diseases, etc.) before pregnancy, pre-pregnancy body mass index (BMI) 18.5–25, those with a BMI >29.9, and those with primary school or higher education were included. The exclusion criteria included multiple pregnancies, without any formal education, physical disability (that prevented the completion of the data collection forms), and mental health problems. Data were collected with the data collection form and Edinburgh Postpartum Depression Scale.RESULTS. The study was completed with 286 women, 142 cases and 144 control groups. There was no statistical difference between the case and control groups in terms of family type and employment status (p>0.050). While the mean age, pregnancy and number of living children of the women in the case group were statistically higher, their educational status was found to be lower (p<0.050). It was found that women with obesity experienced health problems such as urinary tract infection, anemia, gestational diabetes, psychological problems, and preeclampsia/gestational hypertension at a higher rate than women in the control group (p<0.010), and women in the control group gained 13.94±5.29 kg (p=0.001).CONCLUSION In conclusion, it was found that women in the case group experienced pregnancy, early and late postpartum complications at a higher rate than the control group, while there was no difference between the groups in terms of depression at the end of the sixth week postpartum.
The epigenetic dimension of protein structure
Authors: Azzaz Fodil , Fantini Jacques 
Published: February 2022

Abstract
Accurate prediction of protein structure is one of the most challenging goals of biology. The most recent achievement is AlphaFold, a machine learning method that has claimed to have solved the structure of almost all human proteins. This technological breakthrough has been compared to the sequencing of the human genome. However, this triumphal statement should be treated with caution, as we identified serious flaws in some AlphaFold models. Disordered regions are often represented by large loops that clash with the overall protein geometry, leading to unrealistic structures, especially for membrane proteins. In fact, AlphaFold comes up against the notion that protein folding is not solely determined by genomic information. We suggest that all parameters controlling the structure of a protein without being strictly encoded in its amino acid sequence should be coined “epigenetic dimension of protein structure.” Such parameters include for instance protein solvation by membrane lipids, or the structuration of disordered proteins upon ligand binding, but exclude sequence-encoded sites of post-translational modifications such as glycosylation. In our view, this paradigm is necessary to reconcile two opposite properties of living systems: beyond rigorous biological coding, evolution has given way to a certain level of uncertainty and anarchy.
The relationship between melt structure and viscosity: the effect of different fluxes on CaO–SiO2 slags
Authors: Zhang Xiaobo , Liu Chengjun , Jiang Maofa 
Published: February 2022

Abstract
Na2O, CaF2, B2O3 are commonly used fluxes in metallurgical slags. These fluxes reduce the viscosity of slags are related to changing the melt structures. In this study, molecular dynamics simulation was used to analyze the main effects of Na2O, CaF2, and B2O3 respectively on the melt structure of the traditional CaO–SiO2 metallurgical slags. The results showed that since Na+ ions have only one charge, and the electrostatic restraint between the multi-charged ions and the depolymerized [SiO4]4− tetrahedrons cannot occur on Na+ ions. The overall mobility of the particles in the melt structure is improved with the replacement of Ca2+ with Na+. Therefore, the fluidity of CaO–SiO2–Na2O slags is stronger than that of CaO–SiO2, and the viscosity is reduced. F− ions mainly bond with Ca2+ ions to form complexes. The resulting Ca–F structures destroy the electrostatic restraint between Ca2+ ions and depolymerized depolymerized [SiO4]4− tetrahedrons in the Ca–O structures, and the fluidity of CaO–SiO2–CaF2 slags are improved. The effect of B2O3 on the melt structure of CaO–SiO2 is related to the basicity. In this study, when the value of basicity is 1.87, the addition of B2O3 increases the degree of polymerization of the CaO–SiO2 melt structure, and the viscosity may increases.

Abstract

Objectives
To determine the impact of antenatal corticosteroids (ACS) on neonatal outcomes in a large United States population of preterm births.

Methods
Retrospective cohort study utilizing the United States Natality Live Birth database from the Centers for Disease Control and Prevention (2016–2017). Women with singleton preterm births were eligible for inclusion. Out-of-hospital births, fetal anomalies, and cases where ACS exposure was unknown were excluded. Neonates from reported live births were divided into two groups based on whether the mother received ACS before delivery or not. The incidence of several reported neonatal outcomes were compared between the two groups at each gestational week. Subsequently, comparisons between three gestational age groups (23 0/7 to 27 6/7, 28 0/7 to 33 6/7, and 34 to 36 6/7 weeks) were performed. Statistical analysis included use of Chi-squared test and multivariate logistic regression.

Results
Of the 588,077 live births included, 121,151 (20.6%) had been exposed to ACS. ACS use was associated with a significantly decreased odds of neonatal mortality and 5-min Apgar score <7, but an increased rate of several neonatal outcomes such as surfactant replacement therapy, prolonged ventilation, antibiotics for suspected neonatal sepsis, and neonatal intensive care unit (NICU) admissions.

Conclusions
ACS administration prior to preterm birth is associated with a decrease in neonatal mortality and low Apgar scores, and increased odds of several adverse neonatal outcomes.

A perceptual study of language chunking in Estonian
Authors: Ots Nele , Taremaa Piia 
Published: February 2022

AbstractTwo studies investigate the production and perception of speech chunks in Estonian. A corpus study examines to what degree the boundaries of syntactic constituents and frequent collocations influence the distribution of prosodic information in spontaneously spoken utterances. A perception experiment tests to what degree prosodic information, constituent structure, and collocation frequencies interact in the perception of speech chunks. Two groups of native Estonian speakers rated spontaneously spoken utterances for the presence of disjunctures, whilst listening to these utterances (N=47N=47) or reading them (N=40N=40). The results of the corpus study reveal a rather weak correspondence between the distribution of prosodic information and boundaries of the syntactic constituents and collocations. The results of the perception experiments demonstrate a strong influence of clause boundaries on the perception of prosodic discontinuities as prosodic breaks. Thus, the results indicate that there is no direct relationship between the semantico-syntactic characteristics of utterances and the distribution of prosodic information. The percept of a prosodic break relies on the rapid recognition of constituent structure, i.e. structural information.
The Declining Pension Wealth of Employment for the Birth Cohorts 1935–1974 in Germany
Authors: Mika Tatjana 
Published: February 2022

Abstract
Social inequality in the labor market leads to similarly unequal pension entitlements. From a life-course perspective, however, there are two components of inequality in the labor market: the degree of stability of employment until retirement, as well as the amount of gross income earned in periods of employment. The following analysis focuses on working-life and income trajectories of the birth cohorts 1935–1974 in East and West Germany until age 40. The results demonstrate a structural shift in the German labor market towards less stable employment in the first half of the working career. The labor market therefore offered increasingly less stable employment, with an especially stark negative trend for East Germans. Only West German women born after 1945 experienced a positive trend in employment stability. For employees of all birth cohorts, the analysis demonstrates that instability in the employment career has a strong negative effect on income and, subsequently, on pension wealth. The impact of income discrimination against those with less employment stability thus remained similar for the later-born despite the more widespread experience of employment interruptions.
A Critical Period for Development of Cerebellar-Mediated Autism-Relevant Social Behavior

Published: February 2022

The cerebellum has been increasingly implicated in autism spectrum disorder (ASD) with many ASD-linked genes impacting both cerebellar function and development. However, the precise timing and critical periods of when abnormal cerebellar neurodevelopment contributes to ASD-relevant behaviors remains poorly understood. In this study, we identify a critical period for the development of ASD-relevant behaviors in a cerebellar male mouse model of tuberous sclerosis complex (TSC), by using the mechanistic target of rapamycin (mTOR) inhibitor, rapamycin, to pharmacologically inhibit dysregulated downstream signaling. We find independent critical periods during which abnormal ASD-relevant behaviors develop for the two core ASD diagnostic criteria, social impairments and behavioral flexibility, and delineate an anatomic, physiological, and behavioral framework. These findings not only further our understanding of the genetic mechanisms underlying the timing of ASD-relevant behaviors but also have the capacity to inform potential therapies to optimize treatment interventions.SIGNIFICANCE STATEMENTNo targeted treatments currently exist for autism spectrum disorder (ASD). This complex developmental disorder has established links to genetic and circuit aberrations, yet the precise timing and coordination of these underlying mechanisms that contribute to the spectrum of physiological and behavioral abnormalities remains unclear. Cerebellar pathology is consistently seen in ASD individuals; therefore, we sought to identify the specific windows for cerebellar involvement in the development of ASD-relevant behaviors. Using pharmacologic treatment paradigms, we outline distinct critical periods of developmental vulnerability for ASD-relevant social and inflexible behaviors. From this study, we posit a refined window of time during which ASD symptoms develop that will inform therapeutic timing.

Analizy mikroskopowe materii organicznej mają kluczowe znaczenie w analizie systemów naftowych i poszukiwaniach złóż węglowodorów. Informacje o składzie macerałowym oraz stopniu zaawansowania przemian termicznych są nieodzowne w typowaniu perspektywicznych rejonów poszukiwawczych, modelowaniu procesów generacji oraz we wszelkiego typu aspektach geologicznych, w których skały macierzyste pełnią priorytetową rolę. Przeanalizowano skład macerałowy i dojrzałość rozproszonej materii organicznej w wybranych wydzieleniach litostratygraficznych jednostki dukielskiej. Materiał badawczy stanowiło 50 próbek, pobranych z 23 odsłonięć. Próbki pochodziły z warstw inoceramowych, hieroglifowych, menilitowych i krośnieńskich oraz z łupków pstrych i warstw z Majdanu. Zasadnicza część badań obejmowała obserwacje mikroskopowe w świetle odbitym i UV, a także pomiary refleksyjności witrynitu. W celu pełniejszej interpretacji, w przypadku części próbek wykonano pirolizę Rock-Eval. Skład materii organicznej pod kątem jakościowym wydaje się zbliżony – najczęściej obserwuje się zarówno macerały z grupy witrynitu, jak i liptynitu i inertynitu. Ewentualne różnice uwypuklają się w proporcjach pomiędzy udziałem macerałów z tych grup. W obrębie grupy witrynitu wyróżniono większe fragmenty kolotelinitu (>10 µm) oraz mniejsze witrodetrynitu (<10 µm). Grupa macerałów liptynitu zdominowana jest przez alginit, rzadziej natomiast obserwuje się bituminit, liptodetrynit, sporynit i kutynit. Macerały z grupy inertynitu to najczęściej pokruszone fragmenty semifuzynitu oraz fuzynitu oraz drobniejszy inertodetrynit. Dodatkowo w pojedynczych próbkach obecne są stałe bituminy, czasem mogące wykazywać zjawisko fluorescencji. Udział materii organicznej (parametr TOC) jest bardzo zróżnicowany – od <1% do 9%. Ze względu na zasobność w materię organiczną przebadane skały podzielono na skały o niskim (łupki pstre, warstwy z Majdanu, warstwy hieroglifowe), średnim (warstwy inoceramowe), wysokim (warstwy menilitowe) i zmiennym (warstwy krośnieńskie) TOC. Przebadane próbki wykazują również zróżnicowanie w proporcjach grup macerałów, charakteryzując się zarówno dominacją materiału witrynitowo-inertynitowego (warstwy inoceramowe i warstwy z Majdanu), jak też materiału witrynitowego (warstwy hieroglifowe), a także liptynitowego lub witrynitowo-liptynitowego (warstwy menilitowe). Przebadana materia organiczna znajduje się na różnym stopniu przeobrażeń termicznych – od fazy niedojrzałej po późne „okno ropne”. Wydaje się, że w ujęciu regionalnym stopień dojrzałości rośnie w kierunku południowym i południowo-wschodnim.
