Shaping mental resilience of children and adolescents in the face of contemporary trends, which are risk factors for psychosocial health
Authors: Curyło-Sikora Patrycja
Published: June 2022

As a result of dynamic political, economic, socio-cultural and technological changes, modern man lives in a world of constant progress and development. New possibilities and technologies of today's civilization, on the one hand, make life easier for an individual in almost every area of its functioning. On the other hand, they may pose a threat to its development. Clinical observations and empirical reports indicate that the percentage of children and adolescents with various difficulties and psychological disorders is increasing. The article is a review and refers to two reflections. The first one concerns the factors that pose a threat to the mental health of today's children and adolescents. The second one results from the assumptions of health psychology (health promotion and positive prevention) and concerns the role of adults in shaping and strengthening the health of the young generation in the face of contemporary challenges. The aim of the article is, on the one hand, to draw attention to the disturbing contemporary trends, which, in the face of psychological knowledge, can be considered risk factors that may contribute to the increase in disorders in the group of children and adolescents and, on the other hand, to draw attention to the need to shape and strengthen the psychological resilience of the young generation by the impact of the communities closest to them – parents and teachers.
Participatory Social Work in Living Environment: Acting, Learning, and Knowledge Co-Production. The School of Łódź
Authors: Granosik Mariusz
Published: June 2022

The Department of Social Pedagogy and Social Rehabilitation, founded by Helena Radlińska at the University of Lodz, has been developing an original variant of participatory social work for many years. A discourse analysis of this production process results in reconstruction its axial anchors (topos), such as: participation, critical perspective, interpretative assessment, non-deliberativity or political work. All those structural elements are processual, as they need to be adapted to changing social settings (e.g. communities getting more virtualized). Furthermore, the historical context must be considered to understand the participatory social work, as it has had a significant impact on the very concept of action, human strengths or structural empowerment. On top of this already quite complex construction is the triad: practice, knowledge, learning, each of its elements can be treated as a different genre of discourse. Interdiscursive integration of the genres is enabled by the traditionally embedded practice of combining research with action and education. The article ends with critical conclusions regarding the risk of following trends, exploitation of service users and the professionalization of everyday life.
Constructivist Inspirations in Social Work with The Family
Authors: Ciczkowska-Giedziun Małgorzata
Published: June 2022

This paper explores the issues of current achievements in the field of the constructivist social work with the family, as well as presents a new perspective on the use of constructivist thought in this area. The constructivist approach was particularly developed in the 1970s. Still, it remains a concept that strongly influences the process of helping the family. Numerous constructivist-oriented methods of working with the family were developed in Europe and the United States; they also inspired Polish social work. The solution-centered approach is the most widespread approach to the constructivist school of thought in Poland. In addition, among a wide range of these concepts we can distinguish: constructive social work by Nigel Parton and Patrick O'Byrne, strengths-based social work by Ann Weick, Charles Rapp, Patrick W. Sullivan, Walter Kisthardt, Dennis Saleebey, the concept of positive practice by Gary Clapton and strengths-based work models (FGC, VIT). Researchers of social work less frequently refer to positions that fall within the current of systemic (operational) constructivism by Niklas Luhmann. The analysis undertaken in the article aims to show the ways of (re) defining the helping process, as well as the role of partners involved in this process in the theories of Heinz von Foerster and Niklas Luhmann.
Social principles of Catholic social science at the basis of social work in Poland
Authors: Kowalewski Tadeusz
Published: June 2022

The author in the introduction shows the need to reflect on social relations. He uses the desk research method with the help of a literature query on the subject and he carries the topic through the prism of sociology, psychology and philosophy. Relating the subject considerations to these disciplines creates the basis for an approach from the perspective of Catholic social teaching. This point of view allows for the articulation of basic social principles which are solidarity, the common weal and subsidiarity. These social principles have a common denominator, which is the dignity of the human being. As the basis of the principles of social life, it is both natural and supernatural. The dignity of the human person is recognized as a universal value. It is the basis of other social principles because it defines the subject of social relations. On the other hand, social relations in social work are governed by the principles of social work, which have been present in Polish practice and theory of social work for almost a hundred years. The author of this paper indicates selected threads of the Polish tradition of social work. These principles are not only purely theoretical, but also apply to the practice of social work. The main goal is to help individuals and families to strengthen or regain the ability to function in society. It is possible by fulfilling appropriate social roles and creating conditions that favor this goal. Based on the catalog of social work principles, the author analyzes their relationship between the social principles and Catholic social teaching. The conducted theoretical reflection leads the author to the conclusion that the principles of social work are compatible with the principles of social life of Catholic social teaching and should be an inspiration for social work in Polish reality.

La négociation collective des congés payés dans le contexte de l’état d’urgence sanitaire
Authors: Richard Katell
Published: June 2022

Le droit de la durée du travail se situe aux confluents de différentes logiques, tour à tour porteur de logiques sociales d’amélioration des conditions de travail, logiques économiques d’organisation de l’entreprise ou instrument des politiques publiques de l’emploi. Pour inédite que la crise sanitaire liée à la pandémie de la Covid-19 puisse être, le législateur a essayé d’atténuer ses effets par la mise en œuvre dans les entreprises de processus de négociation collective déjà éprouvés depuis plusieurs années par le biais de dispositifs d’aménagement du temps de travail, instrument régulièrement éprouvé des politiques publiques de l’emploi. Cet article a pour objet d’analyser le produit de cette négociation collective d’exception au regard des finalités qu’on lui prête, notamment de ses fonctions réglementaires, relais des politiques publiques et organisationnel de l’entreprise, mais aussi au regard des effets produits par sa capacité normative.
Une convention d’expérimentation territoriale, soutien aux parcours professionnels des personnes en situation de handicap
Authors: Berthomé-Lelaure Stéphanie
Published: June 2022

Chaque jour, des personnes en situation de handicap perdent leur emploi ou rencontrent des difficultés pour accéder à un travail. Pourtant, le droit à l’emploi et le droit au travail sont des droits de l’homme reconnus à tout être humain et un certain nombre d’outils juridiques ont été mis en place pour en assurer l’effectivité. Néanmoins, il apparaît, au cours d’entretiens menés auprès de personnes en situation de handicap, d’acteurs de l’entreprise et de professionnels du secteur sanitaire et médico-social, que les obstacles à l’exercice de ces droits ne paraissent pas levés. Il faut être force de propositions. C’est la raison pour laquelle cet article offre une éventuelle solution en proposant l’élaboration d’une convention d’expérimentation, outil de coordination et potentiel levier à l’inclusion professionnelle. Par une analyse du cadre juridique international, européen et national seront mis en exergue les freins et les leviers à l’inclusion professionnelle selon une approche chronologique des parcours. Tout d’abord, la technicité, les délais de traitement et la pertinence de la reconnaissance administrative de la qualité de travailleur handicapé par la Maison départementale des personnes handicapées (MDPH) seront débattus. Ensuite seront prises en compte les transformations en cours des modalités d’accompagnements sanitaires, sociaux et médico-sociaux pour s’adapter aux besoins des personnes et promouvoir leurs droits et leur pouvoir d’agir. Enfin, à partir des dispositifs existants organisés sous forme de plateformes ou de guichets, les enjeux et les modalités de la coordination de l’ensemble des acteurs seront évoqués.

Published: June 2022

Motile sperm cell separation is important in sample preparation for both artificial insemination and cryopreservation of semen. A novel microfluidic device consisting of an inlet microchannel, a separating reservoir and two outlet microchannels was developed to enrich the motile sperm cells of cattle semen samples. Sperm separation was performed in this microfluidic device using a continuous flow process based on the swim up behaviour of motile cells. Separating reservoir allows the high motile sperm cells to swim up and pass through the top outlet of the reservoir. Low and non-motile sperm cells pass through the bottom outlet of the reservoir in the direction of fluid flow. The microfluidic device was fabricated using polydimethylsiloxane (PDMS) and semen samples were infused into the microfluidic device through a syringe pump. Sperm motility was analyzed by Computer-assisted sperm analysis (CASA). More than 80% enrichment of motile spermatozoa in the cattle semen samples was observed after their separation in the fabricated microfluidic device.

NUTRITIVE VALUE OF GUATEMALA GRASS (Tripsacum andersonii) HARVESTED AT THREE STAGES OF MATURITY IN GEDEO AGROFORESTRY SYSTEMS, SOUTHERN ETHIOPIA
Authors: Andualem Dereje , Hundessa Melaku
Published: June 2022

Background: Gedeo agroforestry is characterized as the integration of trees, crops and livestock on the same unit of land. Land scarcity is a common characteristic in the Gedeo agroforestry system.  Hence integrating forage crops with the agroforestry system is one of the options to alleviate feed scarcity in the area. Objectives: To evaluate the biomass yield and nutritional value of Guatemala grass harvested at three stages of maturity: Early (120days), Mid (150days) and Late (180 days) cultivated at three different altitudes (high, medium and low). Methodology: A randomized complete block design with three replications was employed. Morphological parameters and chemical composition were measured at each stage of maturity and altitude. Result:  The results showed that the number of leaves per plant (NL), plant height (PH), leaf length (LL) and dry matter yield (DMY) exhibited (p<0.05) an increasing trend as harvesting days were delayed. Contrarily the number of tillers (NT) showed (p<0.05) decreasing trend as harvesting dates advanced. The highest (p<0.05) CP (12.6±0.25%DM) was recorded at 120 days. The highest (p<0.05) NDF (61.27±0.07%DM) and ADF (42.3±0.91%DM) were recorded at 180 days of harvesting. The highest (p<0.05) IVDMD (56.7±1.97%) was recorded at 120 days of harvesting, whereas the least (p<0.05) (48.0±2.06) was at 180 days of harvesting. Generally, as the harvesting date advanced, CP and IVDMD showed a decreasing trend, whereas the fiber content (ADF, NDF and ADL) showed an increasing trend. Implication: Based on the morphological characteristics and dry matter yield, the best harvesting stage of Guatemala grass was at the late (180days) stage of maturity. On the other hand, considering the chemical composition and IVDMD, the best harvest stage was at the early (120days) stage of maturity. Conclusion: Cutting Guatemala grass at the proper growth stage is crucial for forage management.  However, to fully utilize the potential of Guatemala grass, further studies on live animal experiments should be carried out.
Perceptions of Computer-assisted Interpreting Tools in Interpreter Education in China’s Mainland: Preliminary Findings of a Survey
Authors: Wan Hongyu , Yuan Xiaoshu
Published: June 2022

Computer-assisted interpreting (CAI) tools are increasingly used particularly for terminology accuracy and efficiency. However, the perceptions of the usefulness of CAI tools’ are mixed. This article analyses the perceptions of CAI tools in interpreter training based on the findings of a survey distributed to interpreter trainers and trainees in China. Analysis of the 161 responses shows that most respondents are interested in CAI but there is no relevant course available on BA- or MA-level interpreter programs yet while students are keen to learn CAI tools in preparation for the future market. Secondly, the most frequently used CAI tool among Chinese interpreter trainees remains online dictionaries whereas the arguably most frequently used terminology management tool in Europe, InterpretBank, is not even in the toolkit of Chinese interpreters. User feedback shows CAI tools mainly help with interpreting preparation, especially in the science and technology domain. Thirdly, it is recommended that CAI be integrated into China’s interpreter education, even though some interpreter trainers have argued about the importance of developing interpreting skills in the first instance. Informed by the findings of the study, this article contributes to the discussion of the possibility of future integration of CAI in interpreter education.

This study aims to determine the effect of the addition of tertiary butylhydroquinone (TBHQ) antioxidants on the quality of biodiesel. Rubber seed biodiesel is synthesized through esterification and transesterification reactions, then biodiesel is characterized by different stages of adding TBHQ antioxidants before the esterification reaction and after the transesterification reaction. The usage of TBHQ antioxidants at the various stages of adding the process greatly affects the quality of biodiesel. The results showed that the addition of TBHQ 1000 ppm after transesterification was the most effective in slowing oxidative degradation by showing the lowest characteristics (acid number 0.64 mg KOH/g and peroxide value 33.91 meq O2/kg) for 3 weeks. All rubber seed biodiesel samples had kinematic density and viscosity according to the Indonesian National Standard (SNI) for 3 weeks except for the acid number only lasted 0 weeks.
Handbook of functional connectivity Magnetic Resonance Imaging methods in CONN
Authors: Nieto-Castanon Alfonso
Published: June 2022

This handbook describes methods for processing and analyzing functional connectivity Magnetic Resonance Imaging (fcMRI) data using the CONN toolbox. The first chapter (fMRI minimal preprocessing pipeline) describes standard and advanced preprocessing steps in fcMRI. These steps are aimed at correcting or minimizing the influence of well-known factors affecting the quality of functional and anatomical MRI data, including effects arising from subject motion within the scanner, temporal and spatial image distortions due to the sequential nature of the scanning acquisition protocol, and inhomogeneities in the scanner magnetic field, as well as anatomical differences among subjects.Even after these conventional preprocessing steps, the measured blood-oxygen-level-dependent (BOLD) signal often still contains a considerable amount of noise from a combination of physiological effects, outliers, and residual subject-motion factors. If unaccounted for, these factors would introduce very strong and noticeable biases in all functional connectivity measures. The second chapter (fMRI denoising pipeline) describes standard and advanced denoising procedures in CONN that are used to characterize and remove the effect of these residual non-neural noise sources.Functional connectivity Magnetic Resonance Imaging studies attempt to quantify the level of functional integration across different brain areas. The third chapter (functional connectivity measures) describes a representative set of functional connectivity measures available in CONN, each focusing on different indicators of functional integration, including seed-based connectivity measures, ROI-to-ROI measures, graph theoretical approaches, network-based measures, and dynamic connectivity measures.Second-level analyses allow researchers to make inferences about properties of groups or populations, by generalizing from the observations of only a subset of subjects in a study. The fourth chapter (General Linear Model) describes the mathematics behind the General Linear Model (GLM), the approach used in CONN for all second-level analyses of functional connectivity measures. The description includes GLM model definition, parameter estimation, and hypothesis testing framework, as well as several practical examples and general guidelines aimed at helping researchers use this method to answer their specific research questions. The last chapter (cluster-level inferences) details several approaches implemented in CONN that allow researchers to make meaningful inferences from their second-level analysis results while providing appropriate family-wise error control (FWEC), whether in the context of voxel-based measures, such as when studying properties of seed-based maps across multiple subjects, or in the context of ROI-to-ROI measures, such as when studying properties of ROI-to-ROI connectivity matrices across multiple subjects.

Objective: The study was conducted to investigate the dephosphorylation of Pseudomonas aeruginosa flagellin (PA FLA) by sweet potato purple acid phosphatase (PAP) and the effect of the enzyme on the flagellin-mediated inflammatory response in the A549 lung epithelial cell line.Methods: The activity of sweet potato PAP on PA FLA was assayed at different pH (4, 5.5, 7, and 7.5) and temperature (25°C, 37°C, and 55°C) conditions. The release of interleukin-8 (IL-8) and the activation of nuclear factor kappa- light-chain-enhancer of activated B cells (NF-κB) in A549 cells exposed to PA FLA treated with or without sweet potato PAP was measured using IL-8 and NF-κB ELISA kits, respectively. The activation of toll-like receptor 5 (TLR5) in TLR5-overexpressing HEK-293 cells exposed to PA FLA treated with or without sweet potato PAP was determined by the secreted alkaline phosphatase-based assay.Results: The dephosphorylation of PA FLA by sweet potato PAP was favorable at pH 4 and 5.5 and highest at 55°C. PA-FLA treated with the enzyme decreased IL-8 release from A549 cells to about 3.5-fold compared to intact PA FLA at 1,000 ng/mL of substrate. Moreover, PA-FLA dephosphorylated by the enzyme repressed the activation of NF-κB in the cells compared to intact PA FLA. The activation of TLR5 by PA-FLA was highest in TLR-overexpressing HEK293 cells at a substrate concentration of 5,000 ng/mL, whereas PA FLA treated with the enzyme strongly repressed the activation of TLR5.Conclusion: Sweet potato PAP has the potential to be a new alternative agent against the increased antibiotic resistance of P. aeruginosa and may be a new conceptual feed additive to control unwanted inflammatory responses caused by bacterial infections in animal husbandry.
Characterization of intrinsic molecular structure spectral profiles of feedstocks and co-products from canola bio-oil processing: impacted by source origin
Authors: Oliveira Alessandra M. R. C. B. de , Yu Peiqiang
Published: June 2022

Objective: Feed molecular structures can affect its availability to gastrointestinal enzymes which impact its digestibility and absorption. The molecular spectroscopy-attenuated total reflectance Fourier transform infrared vibrational spectroscopy (ATR-FTIR) is an advanced technique that measures the absorbance of chemical functional groups on the infrared region so that we can identify and quantify molecules and functional groups in a feed. The program aimed to reveal the association of intrinsic molecular structure with nutrient supply to animals from canola feedstocks and co-products from bio-oil processing. The objective of this study was to characterize special intrinsic carbohydrate and protein-related molecular structure spectral profiles of feedstock and co-products (meal and pellets) from bio-oil processing from two source origins: Canada (CA) and China (CH).Methods: The samples of feedstock and co-products were obtained from five different companies in each country arranged by the Canola Council of Canada (CCC). The molecular structure spectral features were analyzed using advanced vibrational molecular spectroscopy-ATR-FTIR. The spectral features that accessed included: i) protein-related spectral features (Amide I, Amide II, α-helix, β-sheet, and their spectral intensity ratios), ii) carbohydrate-related spectral features (TC1, TC2, TC3, TC4, CEC, STC1, STC2, STC3, STC4, TC, and their spectral intensity ratios).Results: The results showed that significant differences were observed on all vibrationally spectral features related to total carbohydrates, structural carbohydrates, and cellulosic compounds (p<0.05), except spectral features of TC2 and STC1 (p>0.05) of co-products, where CH meals presented higher peaks of these structures than CA. Similarly, it was for the carbohydrate-related molecular structure of canola seeds where the difference between CA and CH occurred except for STC3 height, CEC and STC areas (p>0.05). The protein-related molecular structures were similar for the canola seeds from both countries. However, CH meals presented higher peaks of amide I, α-helix, and β-sheet heights, α-helix:β-sheet ratio, total amide and amide I areas (p<0.05).Conclusion: The principal component analysis was able to explain over 90% of the variabilities in the carbohydrate and protein structures although it was not able to separate the samples from the two countries, indicating feedstock and coproducts interrelationship between CH and CA.

Objective: Water buffalo, an important domestic animal in tropical and subtropical regions, play an important role in agricultural economy. It is an important source for milk, meat, horns, skin, and draft power, especially its rich milk that is the great source of cream, butter, yogurt, and many cheeses. In recent years, long noncoding RNAs (lncRNAs) have been reported to play pivotal roles in many biological processes. Previous studies for the mammary gland development of water buffalo mainly focus on protein coding genes. However, lncRNAs of water buffalo remain poorly understood, and the regulation relationship between mammary gland development/milk production traits and lncRNA expression is also unclear.Methods: Here, we sequenced 22 samples of the milk somatic cells from three lactation stages and integrated the current annotation and identified 7,962 lncRNA genes.Results: By comparing the lncRNA genes of the water buffalo in the early, peak, and late different lactation stages, we found that lncRNA gene lnc-bbug14207 displayed significantly different expression between early and late lactation stages. And lnc-bbug14207 may regulate neighboring milk fat globule-EGF factor 8 (MFG-E8) and hyaluronan and proteoglycan link protein 3 (HAPLN3) protein coding genes, which are vital for mammary gland development.Conclusion: This study provides the first genome-wide identification of water buffalo lncRNAs and unveils the potential lncRNAs that impact mammary gland development.
