Authors: Nguyen Xuan Phuong , Nguyen Dinh Tuyen , Pham Van Viet , Vo Dinh Tung
Published: December 2022

Nowadays, the problem of oil pollution is becoming a big challenge for the environment. Oil pollution threatens the survival of life on land as well as aquatic life. Aware of the seriousness of oil pollution, there have been many scientific studies on solutions to oil spill treatment. The methods can be mentioned as mechanical treatment, microbiological treatment, chemical treatment, absorbent material treatment. Each method has its advantages and disadvantages. In this short review, recent research activities related to the selection of oil-absorbing absorbents and their application in oil absorption are presented. Then, an extensive list of different oil-absorbing materials from the literature, including polymeric materials, porous inorganic materials, and biomass materials, was provided along with their characteristics. Furthermore, the oil adsorption capacity of such materials for different oils and organic solvents has also been discussed to highlight different factors involved in the selection of adsorbent adsorbents. Oil has been tested to separate oil in oil-water mixtures. Finally, some future trends and prospects for oil-absorbing materials are outlined.
IDENTIFYING EROSION HOT SPOT AREAS AND EVALUATION OF BEST MANAGEMENT PRACTICES IN THE TOBA WATERSHED, ETHIOPIA
Authors: Dibaba Wakjira Takala , Ebsa Dessalegn Geleta
Published: December 2022

Ethiopian highlands have been increasingly exposed to the risk of soil erosion and evaluations of how various management practices can reduce the risk of soil erosion are still limited. Here, the calibrated and validated Soil and Water Assessment Tool (SWAT) is used to estimate soil loss rates, identify erosion hotspot areas and evaluate effective best management practices (BMP) to curb the risk of soil erosion. The annual sediment yield (SY) in Toba watershed varies from 0.09 t ha-1 yr-1 to 44.8 t ha-1 yr-1 with an average SY of 22.7 t ha-1 yr-1. Cultivated lands on steep slopes are the sources of extensive soil loss rate, whereas areas with good vegetation cover have low SY. The increased population pressure, increased cultivation of steep slope and uncontrolled grazing are the causes of high SY in the watershed. 17 sub-basins with SY higher than the tolerable erosion of Ethiopia (2-18 t ha-1 yr-1) are considered for the application of BMP scenarios. Implementing all BMPs could reduce the extent of SY but with varying degrees and combination of the BMPs are more pronounced and desirable. Reforestation with vegetative strips was the most effective management (87.8% reduction) followed by soil/stone bund with vegetative strips (83.7% reduction). These findings are important to ensure sustainable land management and promote sustainable agricultural production in a rapidly changing agricultural watershed. In general, the result highlights the need for regional developments and cooperation to urge for strong BMPs strategies for the rapid land and water resources degradation.

Published: December 2022

Precipitation as a major water cycle variable influences the occurrences and distribution of terrestrial water storage change (TWSC), evapotranspiration (ET), and river discharge (Q) of a large river basin. However, its relationship with the other water cycle variables using probabilistic dependence structure concept has not been addressed much. Furthermore, precipitation derived from gauge record is plagued by bias due to orography and under-catch. To fill these gaps, bivariate copula and precipitation derived from reanalysis and satellite data were used. In the present study, the basin-wide averages of the precipitation products APHRODITE, ERA5, and IMERG were used as predictors, whereas the areal mean of MOD16 evapotranspiration, GRACE TWSC, and gauge discharge were used as dependent variables (predictants) for the Brahmaputra basin. The bivariate Archimedean copulas were applied to all the pairs of precipitation-TWSC, precipitation-ET and precipitation-Q based on the optimal marginal distributions obtained. Using the best copula for each pair of the variables, the conditional probability was constructed to predict the predictants for different precipitation amounts (5th, 25th, 50th, 75th, and 95th percentiles). The focus of the analysis was on two scenarios of the predictants (i.e.,≤ 5th and ≥ 95th percentiles). The non-exceedance conditional distribution of TWSC, ET, and Q (all predictants ≤ 5th percentile) decreases with precipitation increase. However, the exceedance probability of the predictants (≥ 95th percentile) increases gradually with an increase in precipitation. The results revealed that both ERA5 and IMERG precipitation data could be used to derive probabilistic measures of the water cycle variables in the absence of gauge-based precipitation.

Published: December 2022

The heterogeneity of infiltration has a strategic influence on the hydrological process in the watershed, and one of the factors affecting its rate and soil compaction is land use. Therefore, this study aims to compare infiltration rates in three land-use areas, namely secondary forest, agroforestry, and moor. A survey method was used, where field data observations were carried out at three locations. The infiltration rate measurement was performed using a double-ring infiltrometer with five repetitions at each sampling site. The results showed that the lowest value of 4.72 cm h-1 was recorded on the moorland, while agroforestry had the highest of 12.87 cm h-1. These findings indicate that land use has a significant role in changing soil physical properties and compaction, hence, sustainable soil and water conservation strategies are needed.

Published: December 2022

Dialysis patients are exposed to more than 40 times more water per week than healthy individuals drink. Therefore, this study aims at how to prevent risk factors that may be in the dialysis water by water quality monitoring to develop a Dialysis Water Safety Plan (DWSP) appropriate for the water source quality and conditions of each dialysis unit to prevent morbidity and mortality associated with dialysis water contaminants. 204 samples were taken from hospitals drinking water before treatment and 342 samples after treatment from 24 dialysis units from 17 hospitals that are fed from surface or underground sources in Giza from April 2020 to March 2021 monthly. Chemical and microbiological analysis were performed according to the American standard methods for the examination of water and wastewater. Visiting the treatment units once a month to monitor any change or inefficiency in any part of the unit. The findings showed that drinking water results were applicable to Egyptian limits except 2.45% for ammonia, iron (9.3%), manganese (6.86%), Total Coliform (2.9%), Escherichia coli (1.96%) and heterotrophic plate count in 1.96%. Hemodialysis water were not applicable for residual chlorine (0.87%), ammonia (1.46%), nitrites (2.6%), sodium(0.58%), potassium (0.29%), calcium (2.05%), magnesium (1.46%), total dissolved solids (1.46%), aluminium (0.58%). Total Coliform (2.6%), and E.coli in (1.46%), Pseudomonas (5.3%) and Streptococcus in (2.6%), and heterotrophic plate count (4.1%). But after the corrective actions according to DWSP, all samples became applicable. Thus, it is clear that DWSP should be implemented by developing an understanding of the system and its ability to provide safe dialysis water

Obrar en consecuencia. La lógica de la experiencia de John Dewey
Authors: Arenas Llopis Luis
Published: December 2022

A pesar del escaso eco que las contribuciones de Dewey parecen haber logrado en el campo de la lógica, la ampliación que ha sufrido la disciplina lógica en la segunda mitad del siglo XX y en lo que llevamos del siglo XXI puede considerarse en muchos sentidos una confirmación de las ideas de Dewey en torno al papel de la lógica en el conjunto del saber. La lógica, en el preciso sentido que Dewey otorga al término, ha sido la preocupación constante del recorrido intelectual de Dewey y es la cima que corona su proyecto de una naturalización de la filosofía. En el caso de la lógica, ese proyecto pasa por mostrar en qué sentido las formas lógicas surgen en la operación de investigar y se ocupan de controlar la investigación para que esta pueda producir aserciones garantizadas. Lo que tendrá como consecuencia asumir el carácter empírico de los principios lógicos y una reformulación radical del problema clásico de la verdad.

Authors: Grubnik V. V. , Evsikov B. V. , Gerasimov D. V.
Published: December 2022

Objective. Estimation of the clinical results application, concerning various methods of the complex choledocholithiasis treatment.

Materials and methods. The investigation was conducted on the base of Odessa Regional Clinical Hospital during 2018 - 2021 yrs. Retrospective analysis of clinical results in treatment of 69 patients with complex choledocholithiasis was accomplished.

Results. The tactics of treatment choice in complex choledocholithiasis must be maximally individualized and depend on a patient state and presence of concurrent diseases. In severe state of a patient the treatment must be started with transhepatic drainage of biliary ducts. It permits to eliminate the cholangitis signs, to improve a patient state and to prepare him to more complex operative interventions.

Conclusion. In complex choledocholithiasis it is expedient to perform a two-staged interventions with preliminary drainage of biliary ducts for the cholemia level lowering. Tactics of treatment of complex choledocholithiasis must be selected, taking into account the patient state and age, presence of concomitant pathology and the clinic-anatomic peculiarities of the disease course (dimensions of calculi, stenosis, diverticulas of common biliary duct, etc). The extended endoscopic interventions constitute the most secure option.

Authors: Büyükbezirci Gülçin , Arıcan Şule , Topal Ahmet , Yılmaz Resul , Alkan Selman
Published: December 2022

Background/Aim: Optic nerve sheath diameter (ONSD) measurement is one of the non-invasive techniques used for intracranial pressure (ICP) measurement. ICP changes have been evaluated based on ONSD measurements during many laparoscopic surgeries. However, such analyses in the obese patient populations are limited. This study aimed at investigating the effects of pneumoperitoneum and reverse Trendelenburg and head-up position on ICP based on ONSD measurements in obese patients undergoing laparoscopic cholecystectomy. Methods: This observational study included 60 female patients who were scheduled for laparoscopic cholecystectomy. Obese patients with a body mass index (BMI) of 30 and above were assigned to Group 1, while BMI < 30 patients were assigned to Group 2. The first ONSD measurement was performed just before insufflation (T1). The second measurement was taken 5 min after insufflation (T2), the third measurement 5 min after placing patients in the reverse Trendelenburg and head-up position (T3), and the last measurement 5 min after the deflation while the reverse Trendelenburg and head-up position was maintained (T4). Results: ONSD measurements at the T2 and T3 time points in Group 1 patients were higher than in Group 2 patients (P = 0.012 versus P = 0.020). Both measurement values were higher in obese patients. In Group 1 patients, T2 and T3 measurements were significantly higher than T1 and T4 measurements (T2 > T1; P < 0.001, T2 > T4; P < 0.001, T3 > T1; P < 0.001, and T3 > T4; P < 0.001). No significant difference between T2 and T3 and between T1 and T4 measurements were found. In Group 2 patients, T2 measurements were significantly higher than the T1, T3, and T4 measurements, while T3 measurements were significantly higher than T1 and T4 measurements (T2 > T1; P < 0.001, T2 > T3; P = 0.022, T2 > T4; P < 0.001, T3 > T1; P < 0.001, and T3 > T4; P = 0.048). No significant difference between T1 and T4 measurements was noted. Conclusion: Laparoscopic cholecystectomy does not cause an increase in ICP of obese patients with limited pneumoperitoneum pressure, reverse Trendelenburg and head-up position, and controlled anesthesia.

Published: December 2022

This paper aims to analyze the impact of drought on the life cycle of barge transportation. The LCA method was used to quantify the environmental impact of barge transportation services on the Madeira River/Brazil: Transportation Operation, Barge Fleet, and Waterway Infrastructure. A model for barge convoy formation was developed as a function of river water level variation. From this, the transport operation was simulated, considering the loading of grains from the Madeira River in 2021, as well as the respective fuel consumption and CO2Eq emissions. The results indicate that barge transportation is more harmful to the environment during drought, since only a convoy of nine barges is allowed to navigate, and its energy efficiency is compromised due to the longer travel time and lower loading capacity in one trip. The intense use of this barge convoy implied an increase of 22.25% in CO2Eqemissions when compared to the full river. Doi: 10.28991/CEJ-2022-08-12-02 Full Text: PDF

Published: December 2022

El teletrabajo es la nueva forma de trabajar, consecuencia de una pandemia que no se esperaba y que llegó para quedarse, comprender lo que se cree conocer del teletrabajo y sus características después de dos años de pandemia es necesario para continuar con esta modalidad de manera exitosa. Por consiguiente, el   presente estudio tiene como objetivo mostrar que las principales características del teletrabajo que son Autonomía, Falta de Información y Aislamiento están ligadas a factores estresantes como sobrecarga de trabajo, conflicto entre el trabajo y la familia y ambigüedad de rol y si influyen o no, de acuerdo con la percepción del teletrabajador en el agotamiento que produce el teletrabajar y la intensión de continuar trabajando de manera remota.  Se realizo una investigación de diseño no experimental con un enfoque cuantitativo y   alcance descriptivo considerando una muestra de 235 teletrabajadores. Para la recolección de información se consideró un instrumento tipo encuesta diseñado con ítems tipo Likert. El análisis de datos se basa en un modelo de ecuaciones estructurales y dentro de los resultados se tiene que a mayor aislamiento en el teletrabajo mayor es la sobrecarga de trabajo percibida por los que hacen teletrabajo y que la ambigüedad de rol se relaciona de manera positiva y muy fuerte con el agotamiento en el teletrabajo, más sin embargo tiene un efecto indirecto parcial con la intención de seguir teletrabajando.

The pitting corrosion resistance of dissimilar pipeline steel API X70 and Super Duplex 2507 Stainless Steel gas tungsten arc (GTA) welds was studied. The GTA welds were fabricated using Super Duplex 2594 Filler Metal or austenitic 309L Filler Metal. The specimens extracted from the base metal, weld fusion zone, fusion boundary, and heat-affected zones (HAZs) were subjected to a potentiodynamic corrosion test in a 3.5% NaCl water solution. The weld made using the 309L Filler Metal was found to have a smaller pitting resistance equivalent number (PREN) difference between ferrite and austenite, making it more corrosion resistant than the weld fabricated using the 2594 Filler Metal. The HAZ on the X70 side was the most susceptible to pitting and galvanic corrosion for both filler metals.

Objetivo: Identificar la capacidad predictiva de variables demográficas y psicosociales en el autorreporte de la salud física de migrantes colombianos y peruanos en Chile. Material y Método: Diseño no experimental de tipo transversal, correlacional, con muestreo intencional. Participaron 853 inmigrantes (51,7% colombianos y 48,3% peruanos; 51% mujeres) entre 18 a 71 años. Se evaluó el autorreporte del estado de salud física, variables sociodemográficas, síntomas ansiosos y depresivos, estrés por aculturación, apoyo social percibido, autoestima individual, entre otros, los que fueron analizados mediante regresión múltiple. Resultados: La población colombiana reportó un mejor estado de salud física. En ambos grupos, los síntomas ansiosos y depresivos fueron importantes predictores del estado de salud física. Otras variables predictivas fueron en peruanos: ingresos económicos, distancia con el país origen y años de permanencia en Chile, en tanto en colombianos: autoestima individual, discriminación y rechazo, y estado de salud actual en comparación con el que tenían en su país. En colombianos, el modelo explica el 14,7% de la varianza, en peruanos un 28,9%. Conclusiones: En ambas poblaciones los síntomas ansiosos y depresivos, y el estrés por aculturación resultaron ser importantes predictores del autorreporte de la salud física, aportando evidencia a que el proceso migratorio afecta el estado de salud mental del migrante y este, a su vez, puede afectar su estado de salud física.
Echi e silenzi: fortuna e sfortuna dell’Agamennonenel teatro musicale
Authors: Casali Giovanna
Published: December 2022

This essay aims to offer some considerations on the reception ofAgamemnonin musical theatre. First of all, it will investigate the reasons why the presence of Aeschylus’ tragedy on the operatic stage is so scant, highlighting the reasons for the compositional and thematic choices that have left the drama in silence. Then, through some specific examples, it will analyse the presence of echoes of theAgamemnonsince, as a tragedy, it had rarely been a source of a specific libretto. In contrast, the Atreus’ house protagonists have had ample fortune as characters in operas concerning, for example, the sacrifice of Iphigenia and not theOresteiatrilogy. The reflection on the reception of Aeschylus’ tragedy will then allow for advancing some general suggestions on a possible path of investigation within the study of the fortune of the ancient Greek classics in musical theatre.
Il bucato di Nausicaa Una nuova lettura di Sofocle, fr. 439 R. (Ναυσικάα ἢ Πλύντριαι)
Authors: Carrara Laura
Published: December 2022

The article starts by reviewing the main evidence concerning Homeric influence on Sophocles’ poetry, with the goal of creating an effective background for the analysis of the presumably most Homeric of his plays, the lost Ναυσικάα ἢ Πλύντριαι (Nausicaa or The Washerwomen). This play demonstrably dramatized the meeting between the castaway Odysseus and the Phaeacian princess as told in OdysseyVI; only three fragments survive (439-441 R.). The article suggests a Homeric hypotext taken from an early scene of that book – the laundry of Nausicaa’s maidens – for fr. 439 R., borne out by a new reading of the much-discussed verb of the line.
‘Schegge’ di Odisseo I ‘volti’ dell’eroe nei frammenti dei drammi odissiaci di Sofocle
Authors: Lupi Francesco
Published: December 2022

The paper focuses on the characterisation of Odysseus in the fragmentary plays of Sophocles. After some introductory remarks on the playwright’s debt to the epic tradition, section 2 deals with the rhetoric of Odysseus as showcased by frs *566 (Syndeipnoi) and 965 R.2 (unknown play), and highlights how Sophocles interacted with the epic tradition underlying both fragments. Sections 3-4 explore the varied way in which Sophocles shaped the ethical characterisation of Odysseus. Section 3 focuses on the role of Odysseus as ‘antagonist’ of other Achaean heroes, while section 4 highlights the unfamiliar characterisation of Odysseus in theEuryalus.
Irony and the Limits of Knowledge in Homer and Sophocles
Authors: Johnston Alexandre
Published: December 2022

This article examines dramatic irony in Homer and Sophocles, focusing on theOdyssey,Oedipus Tyrannus, andAjax. It argues that dramatic irony, which exploits differing levels of knowledge between characters and audiences, is closely linked to conceptions of humans and gods and the gap between mortal and divine cognition. In both Homer and Sophocles, irony is a key conduit through which such theological and epistemological ideas are articulated and communicated. The article identifies significant continuities between the use of dramatic irony in Homer and Sophocles, implying a shared intellectual background, despite some differences.

Humanized liver chimeric mice (PXB-mice) are generated by the transplantation of human hepatocytes into mice that have severe combined immunodeficiency and express an albumin-promoted urokinase-type plasminogen activator (cDNA-uPA/SCID) transgene. Human hepatocytes cannot synthesize
ascorbic acid (AA; commonly called vitamin C) and humans require supplementation to prevent vitamin C deficiency. PXB-mouse livers contain up to approximately 95% human hepatocytes, which likely affects AA synthesis. To determine whether dietary AA supplementation prevents scurvy-like symptoms
and death in PXB-mice, a 12 week study that compared nonsupplemented and supplemented PXB-mice was conducted. Approximately 4 weeks into the study, PXB-mice without dietary supplementation of AA displayed weight loss and clinical signs of hypovitaminosis C, including hunched posture, unkempt
appearance, and lameness. Pathologic evaluation of nonsupplemented PXB-mice revealed lesions consistent with hypovitaminosis C. Mean serum AA concentrations in the nonsupplemented PXB-mice were below the limit of quantitation (0.5 μg/mL) and were substantially less than those of controls.
AA was also measured in a number of tissues, including adrenal gland, brain, liver, and testis; low AA concentrations were similarly observed in tissues obtained from the nonsupplemented PXB-mice. Collectively, these findings support AA supplementation in PXB-mice to prevent the development
of hypovitaminosis C and the potential utility of nonsupplemented PXB-mice as an animal model of scurvy.

Based on the infamous case of the natural disaster of the Armero volcano eruption, this study aims to analyze the perception of the local community towards the development of dark tourism. In particular, the main central question to be addressed in this article is to examine the motivation of tourists and the perception of local residents towards the tourism activity related to this event. To this end, a qualitative methodology was adopted through observation and interview. Our results show that the main motivation of tourists visiting the Armero region is the curiosity to see other people's deaths. However, his feelings change after visiting this region, as curiosity turns to sadness at seeing the suffering of so many people. On the other hand, some locals are not pleased that their history and heritage revolve around tragedy and the dead. This study highlights the lack of awareness of this type of tourism. It is therefore necessary that governments and competent authorities implement measures to encourage the development of this type of tourism. In this way, the cultural impact of black tourism in Colombia can be improved.
Variability of Genetic Parameters of Reindeer Populations of the Chukchi Breed in time and geographical area
Authors: Bryzgalov G. , Ignatovich L.
Published: December 2022

Purpose: Studying the genetic parameters of the population of the Northern Deer of the Chukotka breed according to fragments of molecular multi -cosmic analysis of DNA.

Materials and methods. The northern deer, participating in the experiment year -round grazed on natural pastures without additional feeding. The material for the research was the fabric samples (faster of the auricle) of deer of different sexual age groups. Sampling was carried out by a random method from clinically healthy animals during coral work. Analytical work was carried out in the laboratory of DNA technologies of the All-Russian Research Institute of Tribal case using ISSR-PCR method according to the primer (AG) 9C. DNA allocation and PCR production was carried out with generally accepted methods. For calculations, DNA fragments from 180 to 1400 pp were used, clearly distinguishable visually and form pronounced peaks during computer scanning of gels.

Results. Statistically significant differences between populations in the frequencies of ISSR markers were found in the interval of 1 year in 4-7 loci of 11 identified, through generation-from 1 to 4 loci. With an increase in the temporary interval between observations from 1 year to 5 years, changes in the genome by the number of loci and in the frequencies of ISSR markers were not noted. In all cases, the populations of microsatellites identified were in a state of gene equilibrium. Factors stabilizing the genetic structure of the population of the Chukotka breed are free mating characteristic of the northern deer, a significant number of males participating in the reproduction of the herd. Between populations from various ecological and geographical areas of Chukotka, 6 locus (54.5% of cases) have statistically significant differences in the frequencies of ISSR markers. The population in the Arctic tundra area exceeded the population from the forest tundra along short loci (180-210 pp) and (330- 350 pp) at p <0.001, locals of medium length (350-430 pp) <0.05. In turn, the forest-tundra population exceeded the Arctic population in long loci (700-1300 pp) at p <0.001. Ecological and geographical conditions determine the frequency of ISSR markers in the populations of the Chukchi breed, thereby, being a factor in intraspecific differentiation. Considering that the number of Chukotka breed deer is reduced, constant monitoring of the gene pool is needed. The research was carried out with the financial support of the RFBR in the framework of scientific project No. 20-316-90042.

The efforts shown in recent years related to the reform movements in science education have focused on the assertion that informed nature of science understandings (NOS, hereafter) should be developed. In line with this idea, NOS has become the central component of numerous science curricula. In the study, therefore, it was aimed to determine science education master students’ NOS understandings. The study was conducted in a state university in Turkey during the fall semester of the 2019-2020 academic year and included six science education master students who had taken science methods course. The data were collected through interviews and analyzed by content analysis under phenomenological method. As a result, the students had various and mixed understandings related to the definition of science and characteristics of scientific knowledge. In addition, it was observed that the students handled science with a narrow scope, that they had difficulty in the distinction between theory and law, and that they could not develop informed understandings in the component of theory-laden NOS. In light of these results, the implications and the directions for further study were provided.

Individuals may encounter many negativities due to the misuse of computers and the Internet. Children suffer the most from these negativities. This situation necessitates parents who always protect and stand by their children, to become knowledgeable about the safe use of computers and the Internet. In this study, we examined the opinions of the parents who participated in the safe Internet and computer use training for the parents. The participants of the study were 14 parents of students studying in the 5th and 6th grades in a state secondary school in Bartın. The data of the research were obtained using a semi-structured interview form and a personal information form including demographic characteristics. Qualitative method was used in the research and content analysis was used to analyze the data. In the research findings, the views of parents on safe computer and safe Internet use were examined. It is seen that the general purpose of the parents participating in the training organized on safe Internet and computer use is to improve themselves. When the aims of parents' participation in education are examined; there are reasons such as obtaining information about safe Internet use and completing their deficiencies, learning to use a computer, helping their children and adapting to technology. At the end of the training, the parents stated that they learned about password security, mobile security, the points to be considered in sharing information (such as sharing personal information), harmful software, the use of anti-viruses and the benefits of safe Internet use at the end of the training.

The aim of this study is to examine the effect of an dialogic reading program on expressive language vocabulary and category naming skills, which are among the early literacy skills of preschool children. The research was designed in the quasi-experimental model, which is one of the quantitative research methods. The sample of the study consisted of a total of 30 children, 15 girls and 15 boys, between 64 and 72 months of age, who attended a kindergarten in Konya. Fifteen of the children were in the control group and 15 of them were in the experimental group. In addition to the existing preschool education program applied to the groups within the scope of the study, a 10-week dialogic reading program was applied to the experimental group. In the research, "Demographic Information Form" was used as the data collection tool and "Early Literacy Test (ELT)" was used as pre-test and post-test. According to the results of the research, the post-test scores of all groups' expressive language vocabulary and category naming skills increased significantly compared to the pre-test scores. However, the post-test scores of expressive language vocabulary and category naming skills of the experimental group were significantly higher than the control group. Accordingly, it was concluded that the dialogic reading program applied significantly increased the expressive language vocabulary and category naming skills, which are among the early literacy skills.
Predictive Modeling with Psychological Panel Data

Longitudinal panels include several thousand participants and variables. Traditionally, psychologists analyze only a few variables — partly because common unregularized linear models perform poorly when the number of variables (p) approaches the number of observations (N). Predictive modeling methods can be used when N ≈ p situations arise in psychological research. We illustrate these techniques on exemplary variables from the German GESIS Panel, while describing the choice of preprocessing, model classes, resampling techniques, hyperparameter tuning, and performance measures. In analyses with about 2000 subjects and variables each, we predict panelists’ gender, sick days, an evaluation of president Trump, income, life satisfaction, and sleep satisfaction. Elastic net and random forest models were compared to dummy predictions in benchmark experiments. While good performance was achieved, the linear elastic net performed similar to the nonlinear random forest. Elastic nets were refitted to extract the ten most important predictors. Their interpretation validates our approach and further modeling options are discussed. Code at https://osf.io/zpse3/.
Pitch-Induced Illusory Percepts of Time
Authors: Pazdera Jesse Kendall , Trainor Laurel
Published: December 2022

Past research suggests that pitch height can influence the perceived tempo of speech and music, such that higher-pitched signals seem faster than lower-pitched ones. However, previous studies have only analyzed stimuli separated by up to two octaves. To investigate whether this higher-equals-faster illusion generalizes across the wider range of human hearing, we conducted a series of five experiments. We asked participants to compare the tempo of repeating tones from six different octaves and with fifteen different interonset intervals to a metronomic standard tempo. In Experiments 1–3, we observed an inverted U-shaped effect of pitch on perceived tempo, with the perceived tempo of piano tones peaking between A4 (440 Hz) and A5 (880 Hz) and decreasing at lower and higher frequencies. This bias was consistent across base tempos and was not attenuated by synchronous tapping with the repeating tones. Experiment 4 additionally tested synthetic complex tones to verify that this nonlinearity generalizes beyond the piano timbre, and that it was not related to low-pitched mechanical noise present in our piano tones. Experiment 5 revealed that the decrease in perceived tempo at extremely high octaves can be abolished by exposing participants to only high-pitched tones. Together, our results suggest that perceived tempo depends more on relative pitch within a context than on absolute pitch, and that tempo biases may invert or taper off beyond a two-octave range. We relate this context-dependence to human vocal ranges and propose that illusory tempo effects are strongest within pitch ranges consistent with human vocalization.

Introduction: Age-appropriate feeding in the first two years of life is essential to a child’s growth and development, with health implications that persist throughout life. This study examined the adherence to age-appropriate feeding practices among children 0-23.9 months old based on a constructed index, its association with anthropometric growth, and factors affecting adherence. Methods: A total of 9,138 children aged 0-23.9 months with complete information on infant and young child feeding practices (IYCF), anthropometric measurements, maternal information, and household characteristics were included in the study. Data were extracted from a nationwide survey conducted in 2018-2019. Results: Among children aged 0-23.9 months, 20.7% adhered to age-appropriate feeding criteria. More than half (57.7%) of children below six months adhered to age-appropriate exclusive breastfeeding practices, while 1.4% of children aged 6-8.9 months old started complementary feeding. Continued breastfeeding at 12 months of age while receiving complementary feeding was uncommon (11%). Significantly higher z-scores for weight-for-age (-0.6±0.04), height-for-age (-0.8±0.05), and weight-for-height (-0.2±0.05) were noted among children who adhered to age-appropriate feeding practices compared to those who did not. Child’s age and birth weight, as well as mother’s age, education, and working status, were found to significantly influence the likelihood of adhering to age-appropriate feeding index. Conclusion: Filipino infants and young children under two years of age have low adherence to age-appropriate feeding practices, putting them at a higher risk of repeated occurrence of infection that could lead to stunting in early life.
Рецепция позднего Льва Толстого в польской прессе. Процессы информационного и культурного трансфера
Authors: Piotrowska Joanna
Published: December 2022

The monograph presents a new approach to research surrounding the alter-cultural reception of a writer. The methodological proposals are presented with reference to the reception of Leo Tolstoy. The study focuses on two significant events: his 80th birthday (1908) and his departure from Yasnaya Polyana (1910). A comparative analysis of Polish and foreign publications enabled the author to track the transformations that took place in the way Tolstoy’s image was constructed, and at the same time to better understand the specific nature of press reception mechanisms.

Published: December 2022

Background: Several big cities in Indonesia stated that almost 50% of teenagers had premarital sex. And what is most astonishing is the widespread circulation of sex videos of teenagers wearing school uniforms on the internet. This phenomenon is motivated by the nature of adolescents who tend to want to try all things that are new and challenging. The high presentation of risky behaviour by adolescents needs to be a serious concern for all groups, considering that the transmission of HIV AIDS occurs mainly through sexual intercourse. This study was to see the effect of peer group education on HIV/AIDS on the knowledge and sexual behaviour of adolescents at SMAN 10 Kendari. Methods: This study used a quasi-experimental design with a pre-post test with a control group approach with 60 respondents. Results: There was a significant difference between the mean knowledge scores of the control and intervention groups before and after the intervention with p-value = 0.006, and adolescent sexual behaviour also showed effective results with p-value = 0.046. Conclusion: The peer education method affects knowledge and sexual behaviour, so this method can be used to educate adolescents so that the flow of information delivery is better.
