AbstractThe work describes an ionizing radiation mediated, toxic solvent free interfacial engineering of a novel Phosphorus-Nitrogen functionalized bifunctional cotton cellulose fabric (BCF) endowed with flame retardant (FR) and antibacterial properties. Monomers bis[2-(methacryloyloxy)ethyl] phosphate (B2MEP) and [2-(methacryloyloxy)ethyl]trimethylammonium chloride (MAETC) in different proportions were co-grafted onto cellulose fabric via 60Co radiation mediated Simultaneous Irradiation Grafting Process (SIGP) to incorporate Phosphorus and Nitrogen functionalities. Effects of radiation dose, monomer concentration on the grafting yield (GY) were investigated and samples were characterized using TGA, ATR-FTIR, XRD, SEM–EDX, EDXRF, CHN Elemental Analysis and XPS analytical techniques. Limiting oxygen index (IS:13501/ASTM D 2863) and vertical flammability tests (IS11871-1986) were conducted to establish the halogen free, P-N synergistic FR properties of the fabric. All the co-grafted samples were observed to possess LOI values in excess of 30%, while BCF (1:2) (GY =  ~ 44%) demonstrated LOI of 32% with the least char length of 74 mm in the vertical flammability tests. Tear strength studies were carried out as per ASTMD 1424-09. Antibacterial assay revealed that the fabric possessed activity against both gram positive (S. aureus) and gram negative (E. coli) organisms, with BCF (1:4) (GY =  ~ 48%) demonstrating complete killing of ~ 5 log cycles for both microorganisms in 24 h. BCF retained its FR and antibacterial properties even after multiple washing cycles. With its bonafide green credentials, durability and unique properties, multifunctional BCF fabric prepared under optimized conditions of P/N ratio > 1.7 and GY ~ 45% can be a potential candidate for future applications.

Abstract
Properties which control the mechanical performance of regenerated or precipitated cellulose films are currently not well-known and a mechanistic understanding of the underlying phenomena should be established. Solution rheology is a crucial property for casting films and spinning fibres in terms of process runnability, and it can have a considerable effect on the mechanical properties of the prepared cellulose products. We hypothesized that the viscosity of cellulose dissolved in 4-methylmorpholine N-oxide (NMMO) and the mechanical properties of precipitated cellulose films could potentially be improved by controlling the molecular weight distribution of cellulose pulp, taking inspiration from traditional plastic industry. We evaluated the effects of pulp blends on the viscoelastic properties of dissolved cellulose-NMMO dopes and used the dopes to prepare cellulose films and determined their mechanical properties. Lastly, we employed the determined dope and film characteristics to build linear regression models for predicting dope rheology and mechanical performance of films. Mixture films with 2:1 and 1:2 ratios of pulps with both medium and high degree of polymerization showed in average 36% and 46% higher toughness than their unimodal versions. The model results demonstrated that film performance could be tailored by changing the pulp composition. These findings play an important role in optimizing the future processability of dissolved cellulose dopes for producing bio-based cellulose materials and could bring us a step closer to traditional plastic polymer disciplines by tailoring their performance based on pulp properties.

Effect of eucalyptus globulus pulp properties on fock reactivity
Authors: Cunha André E. P. , Simões Rogério M. S. 
Published: October 2024

AbstractDissolving-grade pulps serve as the primary material for producing regenerated cellulose fibers, and their utilization is steadily increasing. Despite extensive research efforts, it remains necessary to deepen our understanding of the inherent factors that impact pulp reactivity apart from the well-known degree of polymerization. The Fock reactivity test is commonly used to quantify the reactivity of cellulose pulp by measuring the percentage of cellulose that reacts with carbon disulfide. Dissolving pulps typically require a reactivity of over 90%. Hemicellulose content, intrinsic viscosity, cell wall porosity, crystallinity, and accessible area of four different pulps were characterized and distinct treatments were employed to try to separate the effect of different pulp properties and assess their effect on Fock reactivity. Hemicelluloses removal by xylanase and cold caustic treatments (86% removal) increased the Fock reactivity by 30%, from 55.7% to 71.3%. Assuming the hemicelluloses are fully accessible by the CS2, cellulose reactivity increased from 35.6% to 69.5%,but at the expense of an intrinsic viscosity decrease from 990 cm3/g to 689 cm3/g. This unexpected intrinsic viscosity decrease can be due to the cellulose de-shielding effect provoked by hemicellulose removal and some cellulose degradation during cold caustic extraction. Vibrational impact ball-milling applied on a pulp with 5% hemicellulose content notably boosted Fock reactivity by 56%, from 54% to 84.5%, but two pulp properties, intrinsic viscosity, and crystallinity, decreased concurrently due to the high-energy treatment. This phenomenon complicates identifying a direct correlation between heightened reactivity and a single parameter. To address this, endoglucanase treatment was used to separate intrinsic viscosity from crystallinity, clarifying their contributions to changes in Fock reactivity. Unfortunately, the effect of a given physical or bio/chemical pulp treatment affects more than one pulp property, always including the cellulose degree of polymerization, which has made it difficult to isolate the pulp properties that affect Fock reactivity. Several processes have been tested to obtain pulp with dissolving potential.

Published: October 2024

AbstractMitochondria, the cellular powerhouses with bacterial evolutionary origins, play a pivotal role in maintaining neuronal function and cognitive health. Several viruses have developed sophisticated mechanisms to target and disrupt mitochondrial function which contribute to cognitive decline and neurodegeneration. The interplay between viruses and mitochondria might be traced to their co-evolutionary history with bacteria and may reflect ancient interactions that have shaped modern mitochondrial biology.
Peer Support Workers in Mental Health Services: A Qualitative Exploration of Emotional Burden, Moral Distress and Strategies to Reduce the Risk of Mental Health Crisis

Published: October 2024

AbstractThis research aimed to explore the experience of emotional burden among peer support workers (PSWs) in mental health care in Poland. It also examined the issue of moral distress in relation to this professional group and identified institutional sources of support for the well-being of PSWs in the workplace. The data presented in the article are derived from fourteen qualitative in-depth individual interviews with PSWs employed in four mental health centres with different organisational structures. The narratives of PSWs revealed several experiences that could be considered to be moral distress. The inability to assist patients was found to be associated with both individual and institutional barriers. Furthermore, our findings suggest that organisations can implement a number of specific practices to ensure the wellbeing of PSWs, which dissemination would be beneficial to teams employing PSWs.
Simpler Representational Ground
Authors: De Rizzo Julio 
Published: October 2024

AbstractA common way of clarifying the notion of ground is by way of examples from logic: thus a conjunction is grounded in both of its conjuncts; a disjunction in each of its true disjuncts; a double negation in its negatum; and so on. Developing a semantics that accommodates these logical examples in full generality turned out to be a difficult task. In this paper, I develop a novel approach that substitutes fusion for a more discerning relation of combination between states in the framework of truth-maker semantics.
Exploring the Association between Parenting Stress and a Child’s Exposure to Positive Childhood Experiences (PCEs)
Authors: Crouch Elizabeth , Radcliff Elizabeth , Brown Monique J. , Hung Peiyin 
Published: October 2024

AbstractHigh levels of parenting stress, defined as a caregiver or parent feeling stress or aggravation from parenting, has been previously shown to be associated with an increased likelihood of neglect, child maltreatment, and household dysfunction: adverse childhood experiences (ACEs). Despite the potential mitigation of positive childhood experiences (PCEs) on ACEs, prior studies on the increased likelihood of a child experiencing ACEs due to parenting stress have left a critical question unanswered: whether high parenting stress may decrease a child’s likelihood of experiencing PCEs. We analyzed the 2019–2020 National Survey of Children’s Health to examine whether higher levels of parenting stress are associated with the lower likelihood of experiencing PCEs among children. Children with caregivers experiencing high parenting stress had a lower odds of experiencing many types of PCEs, including after school activities (aOR 0.48; 95% CI 0.38–0.57), community volunteer (aOR 0.63; 95% CI 0.52–0.77), and guiding mentor (aOR 0.65; 95% CI 0.50–0.85). Lowering parenting stress through economic supports and parenting programs/interventions could increase the likelihood that a child experiences PCEs.

AbstractThis qualitative study aimed to capture community perspectives of the risks and protective factors for social emotional development and mental health of young children in low-income South Africa settings, and was conducted as one component of a larger study with the ultimate aim of co-designing the Mazi Umntanakho (‘know your child’) digital tool. Twenty focus group discussions (n = 154, 97% female) were held with staff of community-based organisations (CBOs) and community health worker (CHW) programmes in urban and rural sites from four geographical regions. Data were analysed thematically, and grouped according to components of nurturing care (responsive caregiving, safety and security, good health, adequate nutrition, opportunities for early learning) and risk and protective factors. Risks reported by participants far outweighed protective factors, and the most dominant theme identified was risks associated with responsive caregiving from CBO and CHW perspectives. These related to participants’ perceptions of caregivers’ attitudes, knowledge, beliefs, behaviours, and challenges not conducive to the provision of responsive caregiving. The most commonly perceived risks to safety and security were substance abuse, along with economic challenges, neglect, abuse and violence. Basic needs not being met was reported as the main risk to adequate nutrition and good health, followed by insufficient services. Limited resources and caregivers’ limited education and literacy were perceived to be risks to early learning. These findings highlight the urgent need to mitigate risks and amplify protective factors for the social emotional development and mental health of young children in South Africa. It is critical that these are considered within the contextual realities of low-income communities.
Synthesis of crystalline uranyl ion coordination polymers with zwitterionic carboxylate ligands: comparing solvothermal and ambient conditions

Published: October 2024

AbstractTwo neutral, dizwitterionic dicarboxylates,N,N,Nʹ,Nʹ-tetramethylethane-1,2-diammonioacetate (L1) and biphenyl-4,4ʹ-diyl-bis(4-carboxylatopyridiniomethylene) (L2), have been used as ligands in syntheses of uranyl ion complexes which exemplify the effect of different reaction conditions. [UO2(L1)Cl2]·H2O (1) has been crystallized at room temperature and is a simple monoperiodic coordination polymer. In contrast, [(UO2)4(O)2(OH)2(C2O4)(L1)2]·4H2O (2), obtained under solvo-hydrothermal conditions, contains a tetranuclear, bis(µ3-oxido)-bridged cluster resulting from uranyl hydrolysis, and additional oxalate coligands most likely due to oxidative degradation of L1, and it crystallizes as a diperiodic coordination polymer with tetranuclear nodes and thesqltopology. The same arrangement is found in [(UO2)4(O)2(OH)2(L2)3](I3)2·6H2O (3), also synthesized under solvo-hydrothermal conditions, but here the more oxidation-resistant ligand does not generate oxalate, and replacement of the latter by neutral L2 bridges makes this complex cationic. The very large cells of the network in3(~ 22 Å × 39 Å) accommodate the triiodide anions formed in situ.

AbstractUsing a large, representative survey involving 31 countries, we establish stylized facts about the attitudes toward cross-country economic inequality and their correlates. This question has been surprisingly understudied for a topic so important to our globalized $$21^{st}$$

century. We present a simple and intuitive theoretical framework for thinking about cross-country inequalities. Then, we show that people’s perceived and desired levels of domestic inequality and their assessment of their relative socio-economic status closely correlate with how they think about cross-country economic differences. The objective socio-economic status of the individual matters less. Though the impact of country-level variables is less pronounced than individual characteristics, concern about cross-country economic inequality is stronger in more affluent countries and countries with lower income inequality. Our findings illustrate that attitudes toward international economic inequality are intrinsically linked to within-country characteristics, especially to attitudes toward domestic economic inequality.
Meaning of Work Participation After Spinal Cord Injury in Bangladesh: A Qualitative Study in a Low- and Middle-Income Country Context
Authors: Ullah Mohammad Mosayed , Fossey Ellie , Stuckey Rwth 
Published: October 2024

Abstract
Purpose
This study aimed to explore the meaning of work participation for people with spinal cord injury (SCI) in Bangladesh.

Methods
Narrative inquiry methodological framework was used to explore the meaning of work participation after SCI. Face-to-face interviews with twenty adults with SCI, who were either living in the community or in-patients at a rehabilitation center. The Worker Role Interview questionnaire was used as an interview guide. Participants were descriptively analyzed in two groups, rehabilitation participants and community participants. Their transcripts were analyzed using individual narrative analysis to understand the meaning of their experience at an individual level and then the findings from the individual narrative analyses were summarized using thematic analysis to identify themes that collectively represented the meaning of work after SCI in Bangladesh.

Result
Five themes were identified from the interviews: “work life before injury”; “current life in relation to work”; “framing future prospects of work participation”; “motives for working”; and “enablers of work participation.”

Conclusion
The meaning of work is subjective and is influenced by the participants’ pre-existing experiences and other factors related to their work life, such as work preferences, habits, and daily routines. Therefore, creating opportunities to better understand the meaning of work for each individual and incorporating these factors into rehabilitation are keys to sustainable rehabilitation outcomes.
Ergodic theory of diagonal orthogonal covariant quantum channels
Authors: Singh Satvik , Datta Nilanjana , Nechita Ion 
Published: October 2024

AbstractWe analyse the ergodic properties of quantum channels that are covariant with respect to diagonal orthogonal transformations. We prove that the ergodic behaviour of a channel in this class is essentially governed by a classical stochastic matrix. This allows us to exploit tools from classical ergodic theory to study quantum ergodicity of such channels. As an application of our analysis, we study dual unitary brickwork circuits which have recently been proposed as minimal models of quantum chaos in many-body systems. Upon imposing a local diagonal orthogonal invariance symmetry on these circuits, the long-term behaviour of spatio-temporal correlations between local observables in such circuits is completely determined by the ergodic properties of a channel that is covariant under diagonal orthogonal transformations. We utilize this fact to show that such symmetric dual unitary circuits exhibit a rich variety of ergodic behaviours, thus emphasizing their importance.
Assessing rainfall threshold for shallow landslides triggering: a case study in the Alpes Maritimes region, France
Authors: Barthélemy Sophie , Bernardie Séverine , Grandjean Gilles 
Published: October 2024

AbstractIn this work, we use a statistical approach for modeling shallow landslide rainfall thresholds (Caine 1980) with a case study for the Alpes-Maritimes region (France). Cumulated rainfall / duration (ED) thresholds are obtained with the CTRL-T algorithm (Melillo and al. 2018) for different non-exceedance probabilities from a landslide and two climatic datasets. This tool allows to automatically define rainfall events that might trigger landslides, ensuring robustness and objectivity in this process. The first climate dataset stores high resolution gridded rainfall data (1km resolution, hourly), which provides rainfall data with high temporal and spatial accuracy. This dataset, coming from radar data, is calibrated with rainfall gauges, ensuring a higher accuracy of the rainfall measurements. It provides the rainfall records directly used in the threshold construction The second dataset contains lower resolution gridded rainfall, snow, temperature, and evapotranspiration data (8km resolution, daily); it enables to assess the region’s climate through parameters imported in CTRL-T. The thresholds are then validated using a method designed by Gariano and et al. (2015). Several improvements are made to the initial method. First, evapotranspiration values approximated in the process are replaced by values from the second climate dataset, the result accounting best for the regional climate. Then, computing duration values used for isolating events and sub-events for each mesh point allows to consider the heterogeneity of the Alpes-Maritimes climate. Rainfall thresholds are eventually obtained, successively from a set of probable conditions (MRC) and a set of highly probable conditions (MPRC). The validation process strengthens the analysis as well as enables to identify best performing thresholds. This work represents novel scientific progress towards landslide reliable warning systems by (a) making a case study of empirical rainfall thresholds for Alpes-Maritimes, (b) using high-resolution rainfall data and (c) adapting the method to climatically heterogeneous zones.
Impact of rehabilitation with dental implants on the quality of life of patients undergoing maxillofacial reconstruction: a systematic review

Published: October 2024

Abstract

Purpose
Maxillofacial reconstruction with dental implants in microvascular tissue flaps aims to improve mastication. However, the quality of life (QoL) impact of this intervention is yet to be determined. This systematic review assessed the QoL impact of maxillofacial reconstruction with implant-supported teeth compared to no dental rehabilitation, removable dentures, and obturator (modified denture). Additionally, we examined instruments applied to measure QoL in maxillofacial reconstruction.

Methods
Databases Ovid Medline and Embase, Scopus, Web of Science and Handle on QoL were searched. Cohort, case–control and randomized controlled trials (RCT) were narratively synthesized for QoL captured through validated instruments. Study methodological quality was assessed using Cochrane Risk of Bias 2 and Risk of Bias in Non-randomized studies of Exposure. Instruments underwent COSMIN content validity analysis.

Results
Of a total of 2735 studies screened, the three included studies (two cohort and one RCT) showed improved QoL with maxillofacial reconstruction compared to obturator and no dental rehabilitation. However, these studies have high risk of bias due to confounding. None of the instruments achieved a sufficient relevance rating for maxillofacial reconstruction, having been designed for other target populations and there is no evidence on their content validity for this population, but the EORTC QLQ30 H&N35 satisfied more COSMIN criteria than the UW-QOL and OHIP-14.

Conclusion
Although studies showed favourable QoL with maxillofacial reconstruction involving dental implants, these have high risk of bias and further studies are needed to establish the impact. Existing QoL instruments lack content validity and tailored instruments are needed for QoL evaluation in maxillofacial reconstruction.
Inequality and risk preference
Authors: Pickard Harry , Dohmen Thomas , Van Landeghem Bert 
Published: October 2024

AbstractThis paper studies the relationship between income inequality and risk taking. Increased income inequality is likely to enlarge the scope for upward comparisons and, in the presence of reference-dependent preferences, to increase willingness to take risks. Using a globally representative data set on risk preference in 76 countries, we empirically document that the distribution of income in a country has a positive and significant link with the preference for risk. This relationship is remarkably precise and holds across countries and individuals, as well as alternate measures of inequality. We find evidence of a steeper gradient between willingness to take risks and inequality for cognitively more able individuals who likely have a better assessment of inequality and for those who are dissatisfied with their income. We present results in favour of our mechanism, which suggests that falling behind one’s reference group increases the appetite for risk taking.
