Phospholipid transfer protein ameliorates sepsis-induced cardiac dysfunction through NLRP3 inflammasome inhibition
Authors: Wang Jian , Hou Jing , Peng Chaohua
Published: March 2024

Cardiomyocyte pyroptosis is a primary contributor to sepsis-induced cardiac dysfunction (SICD). Recombinant phospholipid transfer protein (PLTP) have been demonstrated to possess anti-inflammatory and antiseptic properties. However, the effect of PLTP on SICD remains unknown. In this study, we established the in vivo and in vitro sepsis model with the recombinant PLTP treatment. The survival rates of mice, mouse cardiac function, cell viability, the protein level of proinflammatory cytokine, and lactate dehydrogenase level were evaluated. The cardiomyocyte pyroptotic changes were observed. The distribution of PLTP and NOD-like receptor thermal protein domain associated protein 3 (NLRP3) in mouse myocardial tissue and expression of PLTP, apoptosis associated speck like protein containing a CARD (ASC), NLRP3, caspase-1, interleukin (IL)-1β, and Gasdermin D (GSDMD) were detected. PLTP ameliorated the cecal ligation and puncture-induced mouse survival rate decrease and cardiac dysfunction, inhibited the IL-1β, IL-18, and tumor necrosis factor (TNF)-α release, and blocked the NLRP3 inflammasome/GSDMD signaling pathway in septic mice. In vitro, PLTP reversed the lipopolysaccharide-induced cardiomyocyte pyroptosis, expression of IL-1β, IL-6, TNF-α, and activation of the NLRP3 inflammasome/GSDMD signal pathway. Moreover, PLTP could bind to NLRP3 and negatively regulate the activity of the NLRP3 inflammasome/GSDMD signal pathway. This study demonstrated that PLTP can ameliorate SICD by inhibiting inflammatory responses and cardiomyocyte pyroptosis by blocking the activation of the NLRP3 inflammasome/GSDMD signaling pathway.
High SEC61A1 expression predicts poor outcome of acute myeloid leukemia
Authors: Ji Guo , Yang Xiaofei , Li Jun
Published: March 2024

The malfunction of SEC61A1 has been linked to several types of cancers, but its role in acute myeloid leukemia (AML) remains poorly understood. In this study, we used a series of bioinformatics analysis techniques, including gene expression profiling and proteomic analysis. Our findings were subsequently validated through a series of in vitro experiments, such as SEC61A1 knockdown in cell lines and RT-qPCR. We discovered a significant up-regulation of SEC61A1 in AML patients compared to healthy controls. AML patients with elevated SEC61A1 expression exhibited reduced overall survival compared to those with lower expression. Moreover, SEC61A1 expression emerged as an independent risk factor for predicting the survival of AML patients undergoing allo-HSCT. Our analysis also revealed an association between high SEC61A1 expression and increased signaling pathways related to cell growth. Our study underscores the importance of SEC61A1 expression as a novel prognostic indicator for predicting survival among AML patients, while also identifying it as a promising therapeutic target.

Fast scanning speed and low-power consumption are becoming progressively more and more important in realizing high-performance chiplet optical phased arrays (OPAs). Here, we successfully demonstrated integrated OPAs with multiple waveguides channels based on thin-film lithium niobate-on-insulator (LNOI) platform. Specifically, two lithium niobate (LN) OPA chips have been implemented with 32 and 48 channels LN waveguides, respectively, enabled by electro-optic modulations, which showcases the low power consumption (1.11 nJ/π) and fast operation speed (14.4 ns), showing obvious advantage of the LNOI platform over others. As results, we experimentally achieved a beam steering with a 62.2° × 8.8° field of view (FOV) and a beam divergence of 2.4° × 1.2° for 32 channels, and a FOV of 40° × 8.8° and a beam divergence of 0.33° × 1.8° for 48 channels. This work also demonstrates the feasibility of LNOI platform in scalable OPA chips.

Speciation and mobility of uranium isotopes in the Shu River: impacts for river to sea transfer
Authors: Matveyeva Ilona V. , Burkitbayev Mukhambetkali М.
Published: March 2024

Fresh water outflows to sea are a source of marine contamination by radionuclides, most originating from nuclear industry operations. Usually, these lead to small amounts of radionuclides entering the sea, for example, because of the discharge of cooling water. However, under accident conditions large amounts of radionuclides may enter river systems. The extent of radionuclide transport along freshwater systems and their subsequent dispersal in the ocean depends upon their speciation. This manuscript examines the speciation of uranium, with particular reference to sulphate complexes, along the Shu River in Central Asia with a view to predict its transport along such rivers to receiving seas. The speciation of uranium isotopes in the Shu River (at the border of Kazakhstan and Kyrgyzstan) was determined. Calculations were based on the measured concentrations of Ca2+, Mg2+, Na++K+, HCO3

2−, and of uranium isotopes. These calculations were determined by either titrimetric methods, gravimetric methods or, for uranium isotopes, by alpha-particle spectrometry. Almost all uranium was present as one of three soluble complexes, either [UO2OH]+, [UO2(CO3)2(H2O)2]2− or [UO2(CO3)3]4−. However, despite the significant concentration of sulphate-ions in the water, especially for the Lower Shu in Kazakhstan, the probability of uranium being present as of sulphate complexes in the analyzed water was very low. The presence of soluble ions is consistent with their mobility along freshwater systems and their transfer to the marine environment. No evidence of an effect from influxes of sulphate was identified.
Why Americans Support Strict Counterterrorism Measures: Examining the Relationship between Concern about Terrorism and Public Support for Counterterrorism
Authors: Han Sungil , Kim Wukki , Gordon Quinn
Published: March 2024

After 9/11, contemporary debates on security often place civil liberties and security at opposite ends of the same spectrum, requiring the loss of one for the maintenance of the other. In addition, public concerns about terrorism determine or at least color public perception about government counterterrorism activities. Thus, the current study empirically examines factors influencing the public’s perception of government activities that may infringe upon individual rights, focusing on the effects of concern about terrorism. For this study we use data collected in World Value Survey (WVS) pertaining to respondents from the U.S. The results of a series of regression analysis and structural equation modeling (SEM) indicate that public concern about terrorism is positively associated with support for counterterrorism activities. Moreover, other factors including satisfaction with democracy, community membership and trust in the government are found to play an important role in explaining public support for counterterrorism activities.

expansion method. The main advantage of this method over other methods is that it provides more accuracy of the FO-DEs with less computational work. The fractional-order derivative operator is the Caputo sense. The transformation is used to reduce the space–time fractional differential equations (FDEs) into a standard ordinary differential equation. By putting the suggested strategy into practice, the new closed-form traveling-wave solutions for various values of parameters were obtained. The generated 3D graphical soliton wave solutions demonstrate the superiority and simplicity of the suggested method for the nonlinear space–time FDEs.
Effect of impurity components in titanium gypsum on the setting time and mechanical properties of gypsum-slag cementitious materials

Published: March 2024

The use of titanium gypsum instead of gypsum as a raw material for the preparation of gypsum-slag cementitious materials (GSCM) can reduce the cost and improve the utilization of solid waste. However, titanium gypsum contains impurities such as Fe2O3, MgO, and TiO2, which make its effect on the performance of GSCM uncertain. To investigate this issue, GSCM doped with different ratios of Fe2O3, MgO, and TiO2 were prepared in this study, the setting time and the strength of GSCM at 3, 7, and 28 days were tested. The effects of different oxides on the performance of GSCM were also investigated by scanning electron microscopy, energy spectrum analysis, X-ray diffraction analysis, and thermogravimetric analysis. The experimental results showed that Fe2O3, MgO, and TiO2 all had a certain procoagulant effect on GSCM and a slight effect on the strength. Through micro-analysis, it was found that the main hydration products of GSCM were AFt phase and calcium–alumina–silicate–hydrate (C–(A)–S–H) gels. Fe-rich C–(A)–S–H gels were observed with the addition of Fe2O3, and Mg(OH)2 and M–S–H gels were observed with the addition of MgO. The addition of TiO2 did not result in new hydration products from GSCM.

Published: March 2024

Rodent models, such as mice and rats, are commonly used to examine retinal ganglion cell damage in eye diseases. However, as nocturnal animals, rodent retinal structures differ from primates, imposing significant limitations in studying retinal pathology. Tree shrews (Tupaia belangeri) are small, diurnal paraprimates that exhibit superior visual acuity and color vision compared with mice. Like humans, tree shrews have a dense retinal nerve fiber layer (RNFL) and a thick ganglion cell layer (GCL), making them a valuable model for investigating optic neuropathies. In this study, we applied high-resolution visible-light optical coherence tomography to characterize the tree shrew retinal structure in vivo and compare it with that of humans and mice. We quantitatively characterize the tree shrew's retinal layer structure in vivo, specifically examining the sublayer structures within the inner plexiform layer (IPL) for the first time. Next, we conducted a comparative analysis of retinal layer structures among tree shrews, mice, and humans. We then validated our in vivo findings in the tree shrew inner retina using ex vivo confocal microscopy. The in vivo and ex vivo analyses of the shrew retina build the foundation for future work to accurately track and quantify the retinal structural changes in the IPL, GCL, and RNFL during the development and progression of human optic diseases.
Spatio-temporal variability of small-scale leads based on helicopter maps of winter sea ice surface temperatures

Published: March 2024

Observations of sea ice surface temperature provide crucial information for studying Arctic climate, particularly during winter. We examined 1 m resolution surface temperature maps from 35 helicopter flights between October 2, 2019, and April 23, 2020, recorded during the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC). The seasonal cycle of the average surface temperature spanned from 265.6 K on October 2, 2019, to 231.8 K on January 28, 2020. The surface temperature was affected by atmospheric changes and varied across scales. Leads in sea ice (cracks of open water) were of particular interest because they allow greater heat exchange between ocean and atmosphere than thick, snow-covered ice. Leads were classified by a temperature threshold. The lead area fraction varied between 0% and 4% with higher variability on the local (5–10 km) than regional scale (20–40 km). On the regional scale, it remained stable at 0–1% until mid-January, increasing afterward to 4%. Variability in the lead area is caused by sea ice dynamics (opening and closing of leads), as well as thermodynamics with ice growth (lead closing). We identified lead orientation distributions, which varied between different flights but mostly showed one prominent orientation peak. The lead width distribution followed a power law with a negative exponent of 2.63, which is in the range of exponents identified in other studies, demonstrating the comparability to other data sets and extending the existing power law relationship to smaller scales down to 3 m. The appearance of many more narrow leads than wide leads is important, as narrow leads are not resolved by current thermal infrared satellite observations. Such small-scale lead statistics are essential for Arctic climate investigations because the ocean–atmosphere heat exchange does not scale linearly with lead width and is larger for narrower leads.
EXPERIENCES OF SOCIAL WORKERS IN WORKING WITH HEALTH CARE PRACTITIONERS: A MULTIDISCIPLINARY TEAM APPROACH
Authors: Maxhakana Zama , Sithole Mbongeni Shadrack
Published: March 2024

This article uses role theory as a lens to explain the experiences of social workers working within healthcare multidisciplinary teams, which are characterised by interprofessional dominance and subordination. A qualitative case study design was used to explore and describe the experiences of social workers in working with other healthcare practitioners in multidisciplinary teams. A purposeful sampling technique was used to select sixteen participants from a particular health district. Data were collected through interviews and analysed using thematic analysis. Professional power dynamics, a sense of agency with a need for collaborative contribution, and a lack of understanding of the social work profession are three themes that summarise the findings. The article concludes that the ineffective management of multidisciplinary themes creates a barrier to different professionals’ ability to communicate, work and learn together. The article recommends preparatory training for multidisciplinary team members and the need for a structured framework for interprofessional engagement. Keywords: collaboration, healthcare, healthcare practitioner, multidisciplinary team, social worker, teamwork

Published: March 2024

The article addresses the issue of increasing the diagnostic capabilities of the car's suspension in the EUSAMA test. A new, quantitative approach was proposed to enable the assessment of the degree of wear and clearance of the lower suspension mount. An active diagnostic experiment was performed to model the clearance in the lower suspension mounting. During the research, bolts with different diameters were used. In the signal analysis, wavelet decomposition into 12 levels was performed using the Db4 wavelet. The resonance area of the system was extracted from an approximate signal, which contained 43.5% of the relative energy. From these signals, a number of point vibration measures were calculated. Finally, the maximum value was selected due to its sensitivity to the condition, which was 48% more than the original EUSAMA results. Based on the selected diagnostic parameter, a clearance model allowing for an assessment of the clearance with statistically significant coefficients was developed.

Published: March 2024

The objective of this work is to study the effect of time during the bonding process of alumina with an industrial aluminum 6060 alloy by the technique of solid-state welding at 600°C. Optical microscopy, scanning electron microscopy with energy dispersive spectroscopy, corrosion tests, and microhardness measurements were used as characterization techniques. The extended time during the bonding process had an effect on the microstructure of the interface and its mechanical properties. Oxygen diffusion was detected across the aluminum alloy/alumina interface. A recrystallization reaction developed on the aluminum side during the bonding process, which affected the aluminum alloy hardness values. By bonding metal to ceramic, it allows the use of ceramics in automotive engines to reduce weight, increase thrust-to-weight ratio and operating temperature, and improve working efficiency.
Development of a Dynamic Hitch Lift Controller using a Hybrid Control Strategy in A Heavy Combination Vehicle

Published: March 2024

This study presents a novel hybrid control strategy for the active hitch system, named the Dynamic Hitch Lift (DHIL), comprising a hybrid controller and a force actuator. The controller was designed to mitigate longitudinal load transfer in heavy combination vehicles by reducing the semitrailer pitch rate and rejecting the pitch moment, assisted by the virtual Skyhook moment. The new controller can calculate the desired force of the DHIL actuator to counter incoming load transfer during harsh braking exceeding 0.5 g braking deceleration. The proposed controller was assessed using a verified 12-degrees-of-freedom tractor-semitrailer model in harsh braking tests across different vehicle configurations. The first evaluation involved a stability test to demonstrate the stability of the controller in reducing load transfer across different vehicle configurations. The second evaluation was on controller performance, which revealed that the dynamic vehicle response has efficiently reduced load transfer by up to 9.14%. The third evaluation has focused on the DHIL actuator performance, which indicated that the actuator generated a force of 159,197 N, which translated into a stepper motor torque of 1,695 Nm at a speed of 1,000 rpm. Simulation results affirmed that the proposed DHIL controller was stable and could effectively reduce longitudinal load transfer in heavy combination vehicles during harsh braking.

Published: March 2024

As an important component of the crawler walking device, the track roller needs to withstand strong impact and is prone to failure, which can lead to serious economic losses. This paper focuses on the track roller of the spreader as the research subject and investigates the dynamic contact characteristics between the track roller and the track plate. Using RecurDyn software, a virtual prototype model of the crawler walking device is established to analyze the variation in a vertical dynamic load of the track roller under different working conditions. Simultaneously, a finite element model of the contact between the track roller and the track plate is developed using Ansys Workbench, and its accuracy is verified using Hertz contact theory. Finally, the study discusses various influencing factors on the contact characteristics, including load, curvature of the contacting bodies, and material yield strength. The results indicate that the track rollers experience the highest dynamic load when climbing a slope, reaching a maximum load of 1191.44 kN. Moreover, the maximum contact stress is 1750.4 MPa, and the maximum Mises stress is 921.34 MPa during this operation.  Importantly, when the load reaches 1218 kN, the maximum Mises stress of the track roller is 930.2 MPa, which may lead to roller failure after prolonged use. These findings provide valuable insights for the design and optimization of heavy-duty track rollers and offer significant assistance for various tracked vehicles.

The rapid advancement of information technology and automation marks the 21st century. These conditions encourage an increase in the quality of human resources, one of which is through the realm of education by emphasizing mastery of 4C skills (communication, collaboration, critical thinking and problem-solving, and creative thinking). Cooperative learning is a learning model that emphasizes cooperation and collaboration among students in a study group to solve problems and achieve goals collectively, effectively, and efficiently. The cooperative learning model is relevant to be applied in sociology learning because it emphasizes aspects of collaboration that correlate with sociology learning. Writing this article uses a qualitative approach with the literature study method and data collection techniques by collecting library data from reference books, articles, journals, and other relevant documents—technical data analysis using content analysis techniques. Based on the results of a literature search, it can be seen that the cooperative learning model applied in sociology learning can be an alternative effort to develop 4C skills in students to face the complex 21st century because it emphasizes aspects of collaboration and helps hone communication skills, critical thinking, and creative thinking.

Published: March 2024

In the first part of this paper (by E. Back) the fundamentals of press-drying are reviewed. Effects of process variables in single stage press-drying promoting the flow of wood components (especially lignin) under heat, moisture, and pressure are illustrated. For press-drying of hardwood pulps the role of residual lignin in parenchyma cells, with delayed removal in pulping, is analysed. The possibilities of short, multiple-stage press nips as useful for continuous paper production are exemplified. In the second part (by R. Swenson) the application of the press-drying process is discussed for different paper grades. Various pilot plant approaches to dynamic, i.e. continuous, press drying are shown. The variables which affect the product and process are presented, with the results obtained when going from static press-drying to a dynamic slow speed press-drying machine. The problems of high speed press-drying to a paper machine is shown.
The Analysis of Disturbances Affecting Paper Machines

Published: March 2024

The characteristics of the disturbances affecting the paper web are discussed with particular reference to grammage variation, wet press vibration, and calender barring. Some of the difficulties of investigation are pointed out. It is shown that the usual assumptions of stationarity and linearity may not hold, so that frequency domain analysis must be applied with caution. The key to any investigation lies in the comparison of corresponding spectral components in signals from different points in the system. Two contrasting approaches are compared and discussed: that adopted in the conventional two channel analysis of random data, and that of considering the interrelationship as a vector function of time. The latter approach, embodied in the Vector Correlator, gives considerable insight into the underlying relationship between the variables. Some practical examples are given.

Kemangi is a strong aromatic herb with aphrodisiac activity. The content of secondary metabolites that are antioxidants in kemangi are thought to be able to overcome fertility disorders due to the work of free radicals.  The aim of this study was to screen for phytochemicals and to analyze the activity of 70% ethanol extract of kemangi leaves (Ocimum americanum L.) on the repair of spermatogenic cells in male sprague-dawley rats exposed to lead. The results of phytochemical screening showed that the basil leaf extract was positive for alkaloids, flavonoids, tannins, and saponins. The results of administration of 70% ethanol extract of kemangi leaves at a dose of 50 mg/KgBW, 100 mg/KgBW, and 200 mg/KgBW in rats that had been induced by lead acetate increased the diameter of the seminiferous tubules, the number of pachytene cells, and round spermatid cells compared to the negative control but not significantly different (p > 0.05). The highest increase in all parameters of the spermatogenic cell repair test was given the kemangi leaves extract at a dose of 200 mg/KgBW.

Published: March 2024

Anemia is a medical condition characterized by lower-than-normal hemoglobin (Hb) levels. In pregnant women, anemia can lead to prolonged delivery times, increased bleeding, and shock during contractions. The adverse effects of anemia on the fetus include premature birth, low birth weight (LBW), potential disabilities, and infant mortality. The recommended solution to overcoming anemia in pregnant women is to consume a combination of beetroot juice and green apples juice. Beets contain essential components that can elevate Hb levels, whereas green apples provide minerals and vitamin C, enhancing iron absorption (Fe). This study aimed to investigate the effect of a combination of beetroot juice and green apple juice on Hb levels in pregnant women with anemia. The study population was comprised of 200 normal pregnant women, with a sample size of 15 in trimester III (TM III) with anemia, selected through purposive sampling. The intervention involved administering the juice daily for seven days. Data were collected using observation sheets and easy-to-touch devices. The research design was pre-experimental, utilizing a one-group pre-test–post-test design. This study was conducted within the working area of the Payung Sekaki Public Health Center (PHC) from January to April 2022. Dependent T-test analysis was used for data evaluation. The average Hb level of TM III pregnant women before juice consumption was 9.7 g/dL, which increased to 10.6 g/dL after the intervention. The dependent t-test results, with a 95% confidence level (Cl), indicated a p-value of 0.000, signifying a significant impact of fruit juice on the Hb levels of TM III pregnant women experiencing anemia. These findings suggest that clinical midwives should educate pregnant women about the importance of Fe tablets and the positive influence of fruit juice on Hb levels.

As primeiras décadas do século XXI têm sido fortemente marcadas pelos efeitos generalizados da crise financeira de 2008, resultante de uma bolha imobiliária nos Estados Unidos, mas que logo se generalizou e afetou o mundo todo, assim como pela ascensão política da extrema - direita em diversos países europeus (França, Itália, Espanha, Polônia e Turquia, por exemplo), nos Estados Unidos e no Brasil, com claras ameaças ao sistema liberal-democrático então vigente nessas nações.
EXPOR O FASCISMO: MUSEUS E DITADURAS
Authors: Pasetti Matteo
Published: March 2024

No fim do século XX, numa reflexão sobre a memória coletiva e sobre a sua relação com a história, Krzysztof Pomian (1998, 2001) sublinhou a importância de dois processos paralelos que, na era contemporânea, influenciaram profundamente a percepção social do passado. O primeiro processo é o crescente “interesse dos Estados”, que ao longo dos últimos dois séculos tentaram influenciar a memória coletiva de forma cada vez mais sistemática, através de vários meios: das escolas ao exército, das cerimónias públicas aos monumentos históricos, dos topónimos aos museus. Através da intervenção pública, foram estratificadas várias memórias nacionais e seculares, sobrepondo-se às memórias tradicionais de natureza rural e religiosa e também às mais elitistas, produzidas pelos círculos intelectuais. O segundo processo decorre da “revolução mediática”, ou seja, da proliferação de dispositivos tecnológicos que tornaram cada vez mais fácil gravar, preservar e transmitir os fragmentos visuais e sonoros do passado: fotografia, fonografia, cinema, rádio e televisão, a gravação de vídeo – que, ao longo das últimas duas décadas, foi efetuada também e sobretudo em formato digital – ajudou a criar uma memória coletiva composta que pode ser partilhada por um público cada vez mais amplo.
DERRUBAR O MURO DE 1945: HISTÓRIA E MEMÓRIA DA REPRESSÃO FRANQUISTA (E DA SUA EVOLUÇÃO)
Authors: Casanellas Pau
Published: March 2024

É comum entre a população espanhola – e de além – a perceção da ditadura de Franco como um regime que, apesar da sua natureza inicial violenta e próxima dos fascismos, evoluiu para um modelo de ditadura branda, claramente afastado dos grandes sistemas genocidas do século XX, como o nazismo e o estalinismo. Esse imaginário coletivo estabelece uma distinção clara entre o franquismo originário, que se ergueu durante a Guerra Civil espanhola e os anos da Segunda Guerra Mundial, e aquele outro a que se afeiçoou a partir de meados dos anos 1940, em especial depois da derrota militar das potências do Eixo na Segunda Guerra Mundial e a posterior integração da Espanha no bloco ocidental como aliado anticomunista. De forma similar, também entre a bibliografia especializada tem prevalecido a diferenciação entre um “primeiro” e um “segundo franquismo”, em que a década de 1950 é concebida como uma espécie de dobradiça entre o Franco cruel anterior a 1945 e o franquismo dos anos 1960 e 1970, cuja arquitetura institucional e práticas repressivas teriam mudado de forma substancial. Esta interpretação deve muito às primeiras sínteses sobre o regime1, formuladas sem o apoio de um trabalho de investigação documental prévio e condicionadas por algumas formulações teóricas provenientes da sociologia ou da ciência política, elaboradas no contexto da Guerra Fria – e fortemente condicionadas por ele.

Introduction

Over the past decade, enterococcal bloodstream infection (BSI) shows increasing incidence globally among the elderly and in patients with comorbidities. In this study, we aimed to assess microbiological and clinical characteristics and long-term outcomes of BSIs caused by Enterococcus spp. in adult patients with and without active onco-hematological malignancies hospitalized at a national referral institute.

Methods

A prospective analysis of consecutive enterococcal BSI cases was conducted in the National Institute of Hematology and Infectious Diseases (Budapest, Hungary) between December 2019 and April 2022. We compared characteristics and outcomes at 30-days and 1 year after diagnosis among patients with and without onco-hematological malignancies.

Results

In total, 141 patients were included (median age 68 ± 21 years, female sex 36.9%), 37% (52/141) had active onco-hematological malignancies. The distribution of species was as follows: 50.4% Enterococcus faecalis, 46.1% Enterococcus faecium, 1.4% Enterococcus avium and Enterococcus gallinarum, and 0.7% Enterococcus raffinosus. No statistically significant differences in all-cause mortality rates were observed between patient subgroups at 30 days (32.7 vs. 28.1%; P = 0.57) and 1 year (75.0 vs. 60.7%; P = 0.09).

Conclusion

Enterococcal bloodstream infections yielded a relevant burden of morbidity, but with no statistical difference in long-term outcomes of adult patients with and without active onco-hematological malignancies.
Sociolinguistic awareness as a key factor in reducing linguistic unease
Authors: Mazzoli Maria , Lupica Spagnolo Marta , Dell’Aquila Vittorio
Published: March 2024

This article addresses key issues related to diverse cases of migration to complex multilingual environments within Europe. Data came from three case studies carried out within the scope of the MIME project: (ex-)Yugoslavian refugees to South Tyrol (Italy); Portuguese work migrants to Andorra; and international managers in Vasa (Finland). Data were elicited using qualitative methods (biographical narrative interviews and focus groups) and thematically analysed to identify emic causes of ‘linguistic unease’, the speakers’ perception that their linguistic repertoire is inadequate for communicating with others and the consequent fear that their linguistic performance will be met with judgemental and negative attitudes. Our results show that in all situations, irrespective of the diverse conditions that exist prior to migration or in the destination country, the complex linguistic environment of the recipient society is puzzling for mobile people. In all cases, numerous migrants target the language that they perceive to be easier and most accessible to them, but this also exposes them to some level of linguistic unease. Crucially, migrants’ learning choices rub salt in the wounds of old conflicts that have roots in the historical dynamics of multilingualism of the recipient societies. We argue that raising sociolinguistic awareness about this is crucial to mitigate unease and discrimination in the most vulnerable sections of the migrant population.

What does moral theology expect from philosophical ethics?
Authors: Kraj Tomasz
Published: March 2024

The morality of the New Testament is different from the morality of the Old Testament. There is less specific guidance in the New Testament, and hence “more” human reason is needed to point to and justify particular (especially more specific) moral norms. Therefore, moral theology uses ethics to explain and justify moral norms. This is stated in no. 68 of the Encyclical Letter Fides et ratio. However, such ethics must meet certain basic requirements, e.g. compatibility with Revelation (not contradicting the truths contained therein). The problematics of the interdependence between moral theology and ethics have been addressed by many philosophers and moral theologians. Many textbooks on moral theology discuss the reference to philosophical ethics. Nevertheless, among the most representative authors for the discussion of the relationship between moral theology and ethics in the context of the debate over Karol Wojtyła’s habilitation dissertation are, on the part of philosophy, Kłósak, who was a professor at the Theological Faculty of the Jagiellonian University, where Wojtyła earned his habilitation degree; and Pinckaers, on the part of moral theology, who wrote a commentary on no. 68 of the Encyclical Fides et ratio, which was authored by John Paul II — Karol Wojtyła.
For a Via Pulchritudinis Musicalis. Some Notes for a Musical Spirituality
Authors: Amherdt François-Xavier
Published: March 2024

To aim for the unspeakable divine, nothing beats the via pulchritudinis musicalis, the path of beauty advocated by Christian tradition, from Augustine to Luther and the recent popes, which contains parables to make the “unheard of” of the Spirit heard and to reconcile the disagreements between humans. The article deploys twelve metaphors of musical spirituality, as so many different sounds available to seekers of meaning, singers and musicians of the infinite, playing on the numbers: the sound of silence; the three-tone Trinitarian chord; the seven notes of the divine scale; humanity and the believing community as a four-part choir; the five lines of the staff of existence; the righteousness (justice) of the six strings of the guitar; the transcendence of the Christ melody; the stereophony between heaven and earth; the novelty of the final biblical Maranatha; the two hands and ten fingers of the pianist; song and music for the spiritual journey and liturgy; the 144,000 voices of the hymns of Revelation. For nothing reaches the heart of God beyond words like perfect harmony when the final chord is sounded.
Effects of Centrality of Religiosity and Dyadic Coping on Psychological Well-Being of Married Couples who Postpone Parenthood
Authors: Czyżowska Dorota , Kalus Alicja , Wendołowska Anna
Published: March 2024

Religiosity and dyadic coping are among the factors important for the quality of marriage, satisfaction with the relationship and the sense of happiness of the spouses. Well-being, mainly in the aspect of personal development or life goals, seems to be particularly important for couples planning to conceive a child in the near or distant future. The study involved 51 married couples postponing parenthood. Their dyadic coping, psychological well-being and the centrality of religiosity were studied. The actor-partner interdependence model was used for the dyadic analyses. There were no differences in the well-being between the spouses, however, women rated in dyadic coping and religiosity higher. The centrality of the spouses’ religiosity, and especially the congruence of their religious beliefs, seems to have a significant impact on their well-being. The obtained results seem to shed new light on the importance of dyadic coping by spouses and their religiosity for the well-being of each of them.
