A perfekcionizmus háttere és vetületei az iskolában
Authors: Nagy-Szabó Zoltán
Published: September 2024

A kutatási folyamatunk elsődleges célja az volt, hogy megvizsgáljuk a perfekcionizmus tanulmányi, társas és érzelmi összefüggéseit a magyar közoktatásban. Ehhez feltérképeztük összefüggéseit az önszabályozott tanulással, a társas önértékeléssel, a jólléttel, az önhátráltatással, a szülői nevelési stílussal és a szülők perfekcionizmusával. Összesen három kutatást végeztünk, két pilot vizsgálat és egy nagymintás mérés formájában. Az első két pilot mérés során a Big Three Perfectionism Scale (2016), a Social Self-Esteem Scale (2013), a Parental Authority Questionnaire (1991), a Perfectionistic Self-Presentation Scale-Jr. (2011) és az Academic Self-Handicapping Scale (2001) kérdőíveket adaptáltuk magyar nyelvre, melyek a folyamat végére mind megfelelő jóságmutatókkal rendelkeztek. A nagymintás mérésünkhöz ezeket a mérőeszközöket kiegészítettük az Önszabályozott Tanulás Kérdőívvel (2013), a WHO szubjektív jóllétet mérő kérdéseivel (1998) és néhány tanulmányi attitűdre irányuló háttérkérdéssel. 497 tanuló töltötte ki összesen kérdőíveinket, 235 férfi és 260 nő, többségében 15-17 évesek. Eredményeink alapján a perfekcionistákat nem csak az irreálisan magas elvárásokra törekvés jellemezi, hanem általános közös jellemzőként jelent meg a dimenziók között a teljesítménycélú motiváció, és a különösen erős igény mások szeretetének és elismerésének kivívására. A merev, önkritikus és nárcisztikus perfekcionizmus dimenziók közül az önkritikus perfekcionizmust azonosítottuk a tanulókra legkárosabbként, mivel erős összefüggést mutatott az önhátráltatással, a szorongással, a halogatással és a negatív önhatékonysággal. Ami a szülői nevelés perfekcionizmusra gyakorolt hatását illeti, a gyerekek perfekcionizmusának legjelentősebb előjelzőjeként az autoriter szülői stílust azonosítottuk. A vizsgálat legfontosabb gyakorlati következtetése, hogy a szülőknek és tanároknak olyan helyzeteket kell teremteniük nevelésük során, ahol a gyerekeknek lehetősége adódik megélni a sikert, és dicséretben részesülni. Ez védelmet nyújthat nekik a perfekcionizmus maladaptív dimenziói ellen.
Regeneração e toxicidade
Authors: Bulamah Rodrigo Charafeddine
Published: September 2024

A lenha e o carvão vegetal representam a base do sistema energético haitiano. Calcula-se que 70% da demanda por energia no país é suprida por esses combustíveis. Sobre esse tema, predominam discussões que retratam a produção de carvão como irracional e responsável por um desmatamento supostamente descontrolado no país. A cadeia do carvão é, contudo, mediada por técnicas e afetos que envolvem processos vitais, diferentes regimes de propriedade e herança, cálculos econômicos e ecológicos além da agência de espíritos que habitam a paisagem. A proposta deste ensaio é deslocar o nosso olhar sobre o carvão com o objetivo de trazer à tona outras dimensões da vida nos montes haitianos, particularmente o par regeneração e toxicidade. Para tanto, discutirei alguns elementos dessa cadeia produtiva, enfatizando a economia de sobras e excessos que resultam dessa atividade.

Published: September 2024

Este texto é a condensação de 20 anos de pesquisas nas regiões do Pajeú e do Navio, no Sertão de Pernambuco. Desde 1999 até 2018 efetuei diversos períodos de pesquisa de campo baseados em três municípios situados nas microrregiões do Pajeú e de Itaparica, macrorregião do Sertão. Publiquei 3 livros e inúmeros artigos a respeito da política eleitoral, da administração pública da violência e dos mortos, numa circunscrição cronológica de 120 anos. Aqui, pretendo expor os conceitos que se desprenderam ou que foram expostos por essa longa convivência e mostrar como eles, ao longo de duas décadas, se fecundaram e dilataram uns em contato com os outros. As páginas que se seguem são um fragmento reelaborado do Memorial que preparei para meu exame de Professor Titular da Universidade Federal de São Carlos.
Pessoalidade, janelas indiscretas e intimidade forçada na vivência de um prédio popular
Authors: Pontes Williane Juvêncio
Published: September 2024

A experiência de moradia em um prédio popular na zona sul da cidade de João Pessoa-PB é o que norteia esta reflexão em torno de relações com a vizinhança baseadas na pessoalidade e na intimidade forçada, possibilitada pelas janelas indiscretas dos apartamentos. O residencial X2, no bairro de Mangabeira, é o universo de análise onde transcorrem as dinâmicas cotidianas que configuram a experiência etnográfica de vivenciar trocas intersubjetivas estreitas e duradouras, se baseando em observações, escutas e conversas informais, bem como na participação de situações corriqueiras, para construir o material analítico que sustenta a reflexão. Este artigo é, portanto, uma análise das nuances de como é viver em um prédio popular onde todos se conhecem e tudo é conhecido por todos.

Published: September 2024

In this research, a liability-driven investment strategy is determined which aims to optimize hajj financial management using the Analytic Network Process approach. Based on the results of Benefit, Opportunity, Cost and Risk (BOCR) approach, it shows that in a liability-driven investment strategy, the benefit (excess) and risk components are the most important factors that investors pay attention to. In determining alternative liability-based investment strategies, there are 2 (two) approaches, either by carrying out portfolio immunization (duration matching) or cash flow matching (cash-flow matching). From these two strategies, it was found that the portfolio immunization strategy was the most suitable strategy to be implemented at BPKH in terms of the return and risk dimensions. Then the strategy is implemented through a portfolio-mix combinations between hedging portfolios and growth portfolios (return generating portfolios), and the most appropriate composition based on the dimensions of returns and risks is the hedging portfolio whose magnitude is above the growth portfolio. It can be said that BPKH can carry out a liability-driven investment strategy through a portfolio immunization strategy that contains a hedging portfolio (such as SBSN and corporate sukuk) that is larger than the growth portfolio (such as KIK EBAS, EBAS-SP, KIK DINFRA, KIK DIRE, Limited Investment Mutual Funds, and Direct Investment and Others).
Originality/Value: The novelty of this study is analysing the hajj fund by BPKH in a deeper and specific extent by displaying future liability data.
A pilot study on the potential of photobiomodulation to safely modify symptoms of an overactive bladder
Authors: Bower Wendy F , Whishaw David Michael , Biros Erik , Baldrey Christine , Galea Mary P
Published: September 2024

Background: Photobiomodulation (PBM) may stabilize autonomic neural drive from the pontine micturition Center to the urinary bladder in individuals with overactive bladder (OAB) symptoms. Methods: A safety profile study preceded a single-case experimental design with repeated measures across subjects to establish the safety and effect direction of PBM to modify symptoms in patients with OAB. Results: No adverse events occurred with PBM, specifically blood pressure remained unchanged. Urinary frequency improved significantly during the intervention and at follow-up. PBM therapy was associated with a meaningful impact on OAB-related quality of life and a small to medium-to-high effect size on OAB symptom severity. Conclusion: Nasal application of PBM is safe and may impact OAB symptoms. A controlled trial of PBM in patients with lower urinary tract symptoms is warranted.

Varying the ratios of ammonium heptamolybdate, nitrilotriacetic acid and 2-aminoethanol has made it possible to obtain a concentrated solution of the molybdenum complex, which remains stable during long-term storage and does not release solid sediment. In an aqueous solution, 2-aminoethanol replac-es ammonium groups in ammonium heptamolybdate, producing mixed ammonium-amine derivatives (NH4)n(NH3CH2CH2OH)6-n[Mo7O24], which cause solution instability and precipitation. Ammonium cations in the HMA molecule can be completely replaced by 2-aminoethanol cations in the course of the reaction in aqueous medium with a sixfold molar excess of 2-aminoethanol to obtain the hex-aamine derivative (NH3CH2CH2OH)6[Mo7O24]. In the ternary system ammonium heptamolybdate – ni-trilotriacetic acid – 2-aminoethanol, the formation of highly soluble triammonium [tri-oxo(nitrilotriacetato)molybdate] monohydrate (NH4)3[MoO3L]·H2O (1) is formed, the crystal struc-ture of which has been studied by X-ray diffraction analysis. Using red clover as an example, it has been shown that the resulting solution is agronomically more effective in comparison with a solution of a molybdenum complex with (1-hydroxyethylidene)diphosphonic acid. According to the RSA data, ammonium cations, hydrate water molecules and trioxo(nitrilotriacetato) anions are present in crystal 1 molybdenum, in which molybdenum atoms have the coordination of a distorted square bipyramide with two oxygen atoms of OMo groups and two oxygen atoms of carboxylate ligands in equatorial positions (2,024(5), 1,710(4) and 2,316(5), 2,436(5) Å). The axial angle O(2)Mo(1)N(2) is 147.6(2). The axial positions are occupied by oxygen and nitrogen atoms (the distances O(2)Mo(1) and N(2)Mo(1) are 1,762(5) and 2,185(4) Å accordingly).

A number of scientific studies has shown that isatin α-thiosemicarbazones, as well as their corresponding cyclization products – [1,2,4]triazino[6,5-b]indole-3-thiones – exhibit higher ionization ability, lipophilicity and anti-inflammatory activity than their isomeric isatin β thiosemicarbazones and their cyclization products. In addition, the well-known indomethacin is characterized by lesser anti-inflammatory activity and greater toxicity than the studied isatin derivatives. At the same time, isatin α thiosemicarbazones and their cyclization products are less described in the literature compared to isatin β thiosemicarbazones and [1,2,4]triazino[5,6-b]indole-3-thiones due to complexity and multi-stage nature of their synthesis. This fact explains the importance of obtaining and studying the properties of new derivatives of these compounds. In the present study, 3-allylsulfanyl-1,2,4-triazino[6,5-b]indole has been synthesized for the first time by the reaction of [1,2,4]triazino[6,5-b]indole-3-thione with allyl bromide in DMF-KOH-H2O medium. It is isomeric in structure to 3-allylsulfanyl-1,2,4-triazino[5,6-b]indole, described in the literature. Taking into consideration that several described derivatives of [1,3]thiazolo and [1,3]thiazino[3',2':2,3][1,2,4]triazino[5,6-b]indole systems showed antimycotic activity, оur further heterocyclization of 3-allylsulfanyl-1,2,4-triazino[6,5-b]indole under the action of iodine and bromine in chloroform is interesting from the point of view of obtaining previously unknown intramolecular salts of [1,3]thiazolo[2ʹ,3ʹ:3,4][1,2,4]triazino[5,6-b]indolium. The structure of the compounds synthesized for the first time was confirmed by the 1H, 13C NMR data, as well as X-ray diffraction.

Published: September 2024

The article considers a new method for producing glassy carbon microspheres in solutions containing furfuryl alcohol, ethylene glycol, iso-octylphenol decaethylene glycol (OP-10) and sulfuric acid. The morphology of the microspheres is presented, as well as the results of their electrochemical testing in a solution of 0.1 M KCl, 0.005 M K3[Fe(CN)6], 0.005 M K4[Fe(CN)6]. Using a non-contact thermometer, the dependence of the solution temperature during synthesis (the heat released during the polycondensation reaction) on the volume of added acid was established. The polymer microspheres obtained in the solution were washed, dried, and calcined at 900 °C. The obtained materials were investigated using scanning electron microscopy and X-ray fluorescence elemental analysis. The elemental analysis showed that the materials contained about 98 % carbon, as well as less than 2 % potassium, copper, oxygen, sulfur, and iron. Scanning electron microscopy revealed that the microspheres had a regular spherical shape, well-developed surface and a diameter ranging from 0.5 to 10 microns. On the basis of the data summarizing the characteristic sizes of the microspheres determined by dynamic light scattering, the dependences of their sizes on the ratio of reagents during synthesis were constructed. The microspheres were used for preparation of the paste for an electrode with a mass ratio of microspheres : vacuum oil = 80 : 10. This mixture was stirred into a homogeneous paste and stuffed into a tubular electrode with the 3 mm diameter. The peak current and peak potential values of the electrode with pure microspheres were determined using cyclic voltammetry, with addition of barium hexaferrite as an electrochemical catalyst for the best sample. Among the nineteen solutions studied during synthesis, the most promising is the solution containing 100 mL of ethylene glycol, 5 mL of furfuryl alcohol, 5 mL of OP-10, and 50 m> of sulfuric acid.

La obra, El aprendizaje servicio en el entorno virtual. Pedagogía innovadora para la universidad del siglo XXI, pone en manos del lector la experiencia de varios proyectos de innovación docente desarrollados con la metodología del Aprendizaje-Servicio (ApS) por el Grupo de Innovación Docente de la Universidad Nacional de Educación a Distancia (UNED): Seguridad, Control de fronteras, Migraciones, Derechos humanos y Gestión Pública del Bienestar social, en colaboración con el Ayuntamiento de Madrid. Estos proyectos contribuyen a institucionalizar el ApS en la UNED en línea con lo previsto en los artículos 18.4 y 33.k) de la Ley Orgánica del Sistema Universitario y aportan como principal novedad no solo que su desarrollo se ha realizado totalmente online, sino que incorporan en sus diseños instrumentos de evaluación por parte de los propios estudiantes con el fin de conocer los aspectos que más valoran de las experiencias, recoger sus sugerencias de mejora y saber su opinión en relación a las tres dimensiones siguientes: su participación en el proyecto, el ApS como herramienta metodológica para profundizar en el conocimiento de los indicadores sociales, y la prestación del servicio consistente en proponer indicadores al Ayuntamiento de Madrid para evaluar algunos de sus programas sociales. Para ello, se ha utilizado un método mixto que completa un cuestionario de valoración online en Google Forms con el desarrollo de focus group, también online, realizados a través de Teams. La incorporación de herramientas informáticas como el software NVivo para hacer la transcripción y el tratamiento de los verbatim de las opiniones de los estudiantes de la Facultad de Derecho que han participado en su implementación es otro valor añadido de estos proyectos de Aprendizaje-Servicio. Además, la integración del Aprendizaje-Servicio en la Educación Superior, a través de proyectos llevados a cabo completamente en plataformas virtuales, se afianza como una metodología de enseñanza transformadora que no solo fomenta la justicia social y el desarrollo comunitario, sino que también establece un puente entre la Universidad (incluida la modalidad a distancia) y la realidad, al permitir que sus estudiantes aborden problemas tangibles y reales como parte de su formación curricular. De este modo, el Aprendizaje-Servicio virtual se erige en una estrategia clave para que los discentes estén mejor preparados para enfrentarse a los retos profesionales y sociales del siglo XXI.

Published: September 2024

The scoping review analyses the convergence of corporate governance and corporate tax planning. The aim of this review is to identify the publication trends, key issues and areas of limited understanding in the current academic literature. Corporate governance structures balance the interests of shareholders, management and other stakeholders. Tax planning, on the other hand, involves strategies aimed at reducing an organisation's tax liability while ensuring compliance. Recent studies point to a intricate relationship between these two areas. The extent and form of tax planning activities can be influenced by corporate governance mechanisms, including ownership structure and board composition. Strong, independent boards may be more inclined to favour tax strategies that are consistent with long-term value creation rather than resorting to aggressive tax planning strategies.

Published: September 2024

Context

The biopsychosocial approach to managing low back pain (LBP) has the potential to improve the quality of care for patients. However, LBP trials that have utilized the biopsychosocial approach to treatment have largely neglected sexual activity, which is an important social component of individuals with LBP.

Objectives

The objectives of the study are to determine the effects of manual therapy plus sexual advice (MT+SA) compared with manual therapy (MT) or exercise therapy (ET) alone in the management of individuals with lumbar disc herniation with radiculopathy (DHR) and to determine the best sexual positions for these individuals.

Methods

This was a single-blind randomized controlled trial. Fifty-four participants diagnosed as having chronic DHR (>3 months) were randomly allocated into three groups with 18 participants each in the MT+SA, MT and ET groups. The participants in the MT+SA group received manual therapy (including Dowling’s progressive inhibition of neuromuscular structures and Mulligan’s spinal mobilization with leg movement) plus sexual advice, those in the MT group received manual therapy only and those in the ET group received exercise therapy only. Each group received treatment for 12 weeks and then followed up for additional 40 weeks. The primary outcomes were pain, activity limitation, sexual disability and kinesiophobia at 12 weeks post-randomization.

Results

The MT+SA group improved significantly better than the MT or ET group in all outcomes (except for nerve function), and at all timelines (6, 12, 26, and 52 weeks post-randomization). These improvements were also clinically meaningful for back pain, leg pain, medication intake, and functional mobility at 6 and 12 weeks post-randomization and for sexual disability, activity limitation, pain catastrophizing, and kinesiophobia at 6, 12, 26, and 52 weeks post-randomization (p<0.05). On the other hand, many preferred sexual positions for individuals with DHR emerged, with “side-lying” being the most practiced sexual position and “standing” being the least practiced sexual position by females. While “lying supine” was the most practiced sexual position and “sitting on a chair” was the least practiced sexual position by males.

Conclusions

This study found that individuals with DHR demonstrated better improvements in all outcomes when treated with MT+SA than when treated with MT or ET alone. These improvements were also clinically meaningful for sexual disability, activity limitation, pain catastrophizing, and kinesiophobia at long-term follow-up. There is also no one-size-fits-all to sexual positioning for individuals with DHR.

Published: September 2024

Differential object marking (DOM) is known from a great variety of language families. We present data suggesting that, contrary to what is suggested in recent typological surveys, DOM is also a widespread phenomenon in Austronesian symmetrical voice languages. To do this, we show why the identification of DOM constructions in these languages is difficult, propose a definition for DOM that takes note of the peculiarities of symmetrical voice systems, and briefly review three types of DOM systems attested in the area. Our findings have implications for claims regarding the universality of DOM, and quality control in compiling large-scale typological databases.
Paraquat disrupts the blood–brain barrier by increasing IL-6 expression and oxidative stress through the activation of PI3K/AKT signaling pathway

Published: September 2024

Background

Paraquat (PQ) is a frequently used herbicide with neurotoxic effects after acute or chronic exposure. Although in vitro evidence supports the PQ toxicity to dopamine cells, its in vivo effects (especially the chronic exposure) remain ambiguous. In this study, we investigated the effect of chronic PQ exposure on the blood–brain barrier (BBB) damage and the underlying mechanisms.

Methods

Adult male Sprague Dawley rats and primary human brain microvascular endothelial (PHBME) cells were exposed to PQ as the animal and cell models. Evans Blue staining and hematoxylin & eosin staining were conducted to examine the BBB and brain tissue damages. The inflammatory cytokines were quantified via enzyme linked immunosorbent assay. The changes of PI3K/AKT signaling pathway were detected by western blot.

Results

PQ exposure can cause significant pathological lesions in the brain tissues and the BBB. IL-6 and reactive oxygen species levels were found to be significantly upregulated after PQ exposure in both the animal and cell models. PQ treatment could arrest the cell proliferation and migration in PHBME cells. PQ treatment promoted the phosphorylation of PI3K and AKT, and the application of PI3K inhibitor could attenuate PQ-induced IL-6 production, oxidative stress, BBB disruption, and brain tissue damage.

Conclusion

Our study demonstrated that chronic PQ exposure could impair the BBB function and induce brain tissue damage. The overactivation of the PI3K/AKT pathway, consequent upregulation of IL-6 production, and increased oxidative stress appear to mediate the inflammatory damage resulting from PQ exposure.
Comprehensive Characterization of a Subfamily of Ca2+-Binding Proteins in Mouse and Human Retinal Neurons at Single-Cell Resolution

Published: September 2024

Ca2+-binding proteins (CaBPs; CaBP1–5) are a subfamily of neuronal Ca2+sensors with high homology to calmodulin. Notably, CaBP4, which is exclusively expressed in rod and cone photoreceptors, is crucial for maintaining normal retinal functions. However, the functional roles of CaBP1, CaBP2, and CaBP5 in the retina remain elusive, primarily due to limited understanding of their expression patterns within inner retinal neurons. In this study, we conducted a comprehensive transcript analysis using single-cell RNA sequencing datasets to investigate the gene expression profiles of CaBPs in mouse and human retinal neurons. Our findings revealed notable similarities in the overall expression patterns of CaBPs across both species. Specifically, nearly all amacrine cell, ganglion cell, and horizontal cell types exclusively expressed CaBP1. In contrast, the majority of bipolar cell types, including rod bipolar (RB) cells, expressed distinct combinations of CaBP1, CaBP2, and CaBP5, rather than a single CaBP as previously hypothesized. Remarkably, mouse rods and human cones exclusively expressed CaBP4, whereas mouse cones and human rods coexpressed both CaBP4 and CaBP5. Our single-cell reverse transcription polymerase chain reaction analysis confirmed the coexpression CaBP1 and CaBP5 in individual RBs from mice of either sex. Additionally, all three splice variants of CaBP1, primarily L-CaBP1, were detected in mouse RBs. Taken together, our study offers a comprehensive overview of the distribution of CaBPs in mouse and human retinal neurons, providing valuable insights into their roles in visual functions.

Topography, by spatially altering site conditions, affects ecological processes, e.g. natural forest recovery. Until now the early dynamics of naturally encroaching trees on inland dunes with regard to topography has not been sufficiently studied in detail, and became the aim of our study. To achieve this aim, in 2011 we established a 14.87 ha long-term research site located in the Toruń artillery ground (N Poland), in one of the biggest inland dune fields of Central Europe. We surveyed twice (2011 and 2021) trees occurring in the site, and investigated their characteristics (GPS coordinates, height, diameter, age, annual stem increment, slenderness) regarding 5 topographical variants: north- (N), east- (E), west- (W), and south-facing (S) slopes, as well as intra-dune depressions (D). We found that within the investigated 10 years timespan the number of trees increased almost fourfold (from 560 to 2016). The natural encroaching of trees was the most advanced in north-facing slopes (88 ± 17 and 352 ± 89 trees ha-1 in 2011 and 2021, respectively). In turn, in sunny exposures and in intra-dune depressions the process was the least advanced (in 2021: 64 ± 21 and 25 ± 15 trees ha-1, respectively), which could be primarily linked to unfavourable moisture conditions occurring on south-facing slopes, and strong competitive effect of tall grasses on young trees regarding the depressions. By showing the rate and topographically controlled spatial pattern of trees encroachment, our study can be useful e.g. for practising managers when reforestation of inland dunes by natural means is planned.

Published: September 2024

The Cut-to-Length (CTL) harvesting system is nowadays predominant in the field of mechanized forest operations, consisting mainly in harvesters and forwarders forestry machines. These machines are equipped with an On-Board Computer (OBC) that collects a large amount of information concerning machine parameters such as harvested timber, travelled distance or fuel consumption. Stream machine data are sent to the machine fleet management system (FMS) on cloud, stored and automatically summarized on hourly, daily, weekly, or monthly basis. Understanding the benefits of data mining techniques - in finding trends and patterns - exploiting FMS database in relation to topographic and climatic condition is still an ongoing open research question. The present work aims at verifying if and how machine´s performance indicators (e.g. fuel consumption) recorded and summarized on a hourly basis by the FMS are influenced by site specific parameters, such as terrain morphology, soil type, wet soil condition, and weather conditions, derived from open source portal. A specific methodology in machine data acquisition and datasets implementation has been set in this study. The dataset results in a combination of three sub-datasets, consequently merged, filtered and analyzed. A first sub-dataset is made up of “machine data”, a second is made up of “environmental data”, and a third set of data is made of “climatic data”. The obtained results revealed that the combination of different data sources’ provides significant insight into understanding machine performance. Moreover, the integration of terrain morphology and climatic data have direct impact on the machine fuel consumption, harvester machine in particular. However, in order to address specific interactions among variables with greater robustness, further investigations into this project will consider the whole set of variables on a smaller scale (e.g., case study) with higher data resolution.

Understanding the effects of planted forests on soil properties is of great importance to meet increasing demands for wood production and contributing to forest ecosystem services and soil carbon sequestration. However, the influence of mono- and mixed tree plantations on soil chemical properties remains incompletely explained, particularly in tropical semi-evergreen forests. In this study, a mono-plantation of Michelia champaca and Tectona grandis, as well as their mixed plantation, were studied on soil variables (pH, SOC, N, P, K) at different depths (0-10, 10-20, and 20-30 cm) in tropical semi-evergreen forest of the Khadimnagar National Park, Bangladesh. All examined pedovariables showed no significant differences among plantation types, notably in the surface soil layer (up to 10 cm). However, significant oscillations were found in the deepest soil layer (20-30 cm), where M. champaca and mixed-species plantations obtained the lowest SOC (0.55-0.66%) and N (0.05-0.06%) concentrations. In the intermediate soil layer (10-20 cm) K concentrations were the lowest in M. champaca (19.6 mg/kg) and mixed-species plantation (17.6 mg/kg), while T. grandis recorded the highest K concentration (27.4 mg/kg). Additionally, the results indicated an increase in pH with soil depth (from 5.30 in the topsoil to 7.00 in the deepest layer), with T. grandis showing the lowest values across examined soil layers (5.76-5.95) and significantly differing from M. champaca, which exhibited the highest pH over the soil profile (6.29-6.51). Such results suggest the leaching of basic cations (Ca2+, Mg2+, K+) over the soil profile due to pronounced monsoon rainfalls. Further research is necessary to fully elucidate underlying mechanisms behind the observed impact of examined plantations on chemical soil variables. Considering other variables such as litter chemical composition and various physical and microbiological soil properties can offer valuable guidelines for enhancing more sustainable management of a tropical semi-evergreen forest, prone to soil acidity and water erosion.
The Rhetoric of Silence or Open Demands for Women’s Rights in Public Space? A Case of The Polish Women’s Press From 1989
Authors:   Uniwersytet Marii Curie-Skłodowskiej, Szwed-Walczak Anna
Published: September 2024

The subject of research is the discourse concerning equality in the Polish women’s press (Przyjaciółka, Kobieta i Życie, Zwierciadło, Filipinka) in the first year of the system transformations. The assumption was made that silence was supposed to draw readers’ attention to a given case, make them reflect on it, and stimulate initiatives. The aim of the research was to point to the context in which the issues of women’s activity, the absence of gender equality in practice, were taken up in the Polish women’s press. The research period included the whole year 1989. In order to perform the research the detailed questions were set out: (1) interpretations of which political events in Poland in 1989 generated silence?, (2) how was the silence tactics realised?, (3) in what way was the women’s situation in Poland in 1989 accounted for in the women’s magazines – was it dominated by the stereotypes in which there were presented female features that predestined women to be housewives?
Wzorce matki i macierzyństwa w świetle poznańskich czasopism dla kobiet na przełomie XIX i XX wieku, ss. 262

The PhD dissertation, entitled Image of Mother and Motherhood in Grand Dutchy of Posen women’s magazines at the turn of the 20th century was written under the supervision of dr hab. Agnieszka Szudarek, prof. US. The purpose of this dissertation is to seek an answer to the question of whether the situation in the Province of Posen had any modifying impact on the characteristics of the image of the mothers and motherhoods in that geographical area. The prevailing view in the literature has so far been that there was a single common The Polish Mother Patriot model in place and the mother’s tasks were subordinated to the national mission. The purpose of the dissertation is to demonstrate that the point of view published in the women’s press does not allow such an explicit statement, while at that time the discourse on mothers and motherhood itself was dominated by the „national mission” of women. However, it was postulative. Indeed, on the pages of the analyzed magazines, the need for change arose from the changes in civilization. At moments when anti- polish policies intensified and successive anti-polish laws had come into force, certain elements of the vision of modern motherhood were reinterpreted by women for national needs.
