Authors: Dagupati Rajesh , Klement Róbert , Galusek Dušan 
Published: March 2021

AbstractThe effect of Yb3+ co‐doping on relaxation dynamics of excited states of Er3+ ion in oxyfluoro tellurite (TZYN) glasses was demonstrated employing excitation and luminescence spectroscopy. The up‐conversion luminescence spectra were studied as a function of temperature in the 298–633 K range, and fluorescence intensity ratio (FIR) for green bands due to the 2H11/2 → 4I15/2 and 4S3/2 → 4I15/2 transitions of Er3+ ion against temperature was determined. The temperature sensing performance of TZYN:Er3+/Yb3+ glasses was studied using the FIR technique up to 633 K. The maximum absolute (Sa) and relative (Sr) sensitivity of 0.00246 K−1 at 413 K and 0.72% K−1 at 323 K, respectively, were determined for TZYN:0.5Er3+ /1.0 Yb3+ glass.

AbstractBorate‐based glasses have generated great interest for wound healing applications due to their ability to incorporate biologically therapeutic ions which can then be released at the site of repair attributable to their high dissolution rates. In this study, the anti‐bacterial activity and cytocompatibility of sol‐gel–derived silver‐doped borate glasses (AgBGs) of the compositional range (60)B2O3–(36)CaO–(4–x)P2O5–(x)Ag2O, where x = 0.0, 0.3, 0.5, and 1 (mol.%) were investigated, in vitro. The dose‐dependent anti‐bacterial activity of AgBGs was demonstrated against Pseudomonas aeruginosa under both planktonic conditions and pre‐formed biofilms, with up to 99.7% reduction in bacterial cell counts. Lower concentrations of ionic dissolution products from AgBGs were non‐toxic to keratinocytes, stimulating their growth and metabolic activity. Furthermore, compositions containing 0.3 and 0.5 mol.% Ag significantly accelerated the migration of keratinocytes at two different concentrations in an in vitro 2D wound healing model. In summary, these therapeutic AgBGs have demonstrated potential for accelerated wound healing.

AbstractThe compounds based on calcium molybdate (CaMoO4) are the subject of extensive research due to their excellent optical properties and a broad range of potential technological applications. In this work, we report a systematic study of CaMoO4:Tm3+ phosphors synthesized by coprecipitation and processed in a microwave‐hydrothermal system at low temperature (100°C) and stirring. The effect of the Tm3+ doping content (0%–12%) is studied in full detail to understand their role in the CaMoO4:Tm3+ morphological, structural, and luminescent properties. The X‐ray diffraction, Raman, and Fourier Transform Infrared spectroscopic techniques revealed that all the prepared powders have a tetragonal crystal structure with a distinct density of cation vacancies and structural disorders. The band gap remains almost constant for doping levels lower than 8%, but it narrows strongly for powders doped with 12% Tm3+ ions. The designed phosphors have shown two emission bands in which intensity depends on the Tm3+ ions doping level. For doping levels lower than 2%, the photoluminescence profile displays a broad emission band peaking at 543 nm (green). For concentrations higher than 4%, the band centered at 543 nm decreases in intensity and the near‐infrared emission band at around 800 nm, assigned to 3F3, 3H4 → 3H6 transitions from Tm3+ ion, become more intense. The outcomes of this work reveal that appropriated Tm3+ ions doping levels can be applied to suppress the PL emission in the visible range and improve that in the near‐infrared region in CaMoO4‐based materials.

Published: March 2021

AbstractHerein, Al‐doped Mn1.95Co0.21Ni0.84O4 (MCN)‐microbead structures were successfully prepared using in situ ink‐jet printing technology. The effects of the Al2O3 doping on the electrical properties of the MCN ceramic microbeads were discussed. The R25, B25/50, and Ea values of NTC ceramics thermistors were found to range from 14.14 × 103‒63.21 × 103 Ω, 3635‒3773 K, and 0.3133‒0.3252 eV, respectively. Notably, the ageing coefficient (ΔR/R) of the (Mn–Co–Ni–Al–O) MCNA ceramics was found to be <1.1%, compared to a value exceeding 4.2% for the undoped MCN microbeads. The thermal time constant of the doped microbeads was small, with a value of 33 ms, compared to 8 s for the MCN ceramic chip. In particular, the grain boundaries were determined to play an important role in the overall electric behaviour of the ceramics described here.

Published: March 2021

AbstractWell‐sintered CaO granules with hydration resistance are very important for the manufacturing and application of CaO‐containing refractories. CaO granules with sol‐processed metal oxide protective layers were prepared by granulation and surface treatment. The obtained results indicated that the usage of nano sol greatly improved the hydration resistance of CaO granules, especially when the CaO granules were treated by alumina sol. The promoting effect of nano sols in the sintering processes improved the density of CaO granules. Nanoparticles reacted with lime at lower temperature and a new phase was formed uniformly in the treated layer, which promoted densification of the treated layer. The grain size of CaO granules in the treated layer was increased obviously with the promotion of sintering. Moreover, nanoparticles were favorable for the formation of direct bonding between CaO grains by decreasing the dihedral angle.
Online Shaming and the Ethics of Public Disapproval
Authors: Fritz James 
Published: March 2021

AbstractThis article illuminates an underappreciated tension between two desiderata for moral disapproval. First, moral disapproval should aspire to openness. This means, among other things, that it should aspire not to require silence from wronged parties. Second, moral disapproval should aspire to decency. This means, among other things, that it should not predictably cause psychological harm in a way that alienates or isolates people from their moral community. I illustrate the tension between these desiderata within the context of online shaming and then show how that conflict generalizes. The shape of the conflict is this: in many cases, justice requires us to allow for highly public disapproval about an offender, but the publicity of that disapproval predictably fosters psychological harm, alienation, and isolation. To explain why many cases share this character, I appeal to psychological and philosophical research on the connections between shame, humiliation, aggression, isolation, and depression.

AbstractBLUP (best linear unbiased prediction) is the standard for predicting breeding values, where different assumptions can be made on variance–covariance structure, which may influence predictive ability. Herein, we compare accuracy of prediction of four derived‐BLUP models: (a) a pedigree relationship matrix (PBLUP), (b) a genomic relationship matrix (GBLUP), (c) a weighted genomic relationship matrix (WGBLUP) and (d) a relationship matrix based on genomic features that consisted of only a subset of SNP selected on a priori information (GFBLUP). We phenotyped a commercial population of broilers for body weight (BW) in five successive weeks and genotyped them using a 50k SNP array. We compared predictive ability of univariate models using conservative cross‐validation method, where each full‐sib group was divided into two folds. Results from cross‐validation showed, with WGBLUP model, a gain in accuracy from 2% to 7% compared with GBLUP model. Splitting the additive genetic matrix into two matrices, based on significance level of SNP (Gf: estimated with only set of SNP selected on significance level, Gr: estimated with the remaining SNP), led to a gain in accuracy from 1% to 70%, depending on the proportion of SNP used to define Gf. Thus, information from GWAS in models improves predictive ability of breeding values for BW in broilers. Increasing the power of detection of SNP effects, by acquiring more data or improving methods for GWAS, will help improve predictive ability.

AbstractStroke is a major cause of vascular cognitive dysfunction, such as memory impairment. We aimed to explore the neural substrates underlying verbal memory impairment in subcortical stroke patients by the methods of voxel‐wise cerebral blood flow (CBF) and the functional covariance network (FCN). Sixty patients with chronic subcortical stroke and 60 normal controls (NCs) were recruited into this study. We used a three‐dimensional pseudo‐continuous arterial spin‐labeling imaging to measure alterations in CBF and FCNs. We mapped the overall CBF alterations in a voxel‐wise manner and compared CBF measurements using a two‐sample t test. Correlations between CBF and verbal memory were also investigated. Subsequently, we constructed FCNs by calculating the correlation between specific regions and all other voxels of a whole brain, separately within the two groups. Thereafter, by comparing differences of the FCN patterns between the patient and NC groups, we investigated the connection alterations within the FCN maps. The stroke patients showed verbal short‐term memory (VSTM) deficits compared to NCs. The patients exhibited decreased CBF in the ipsilesional insula and ventral sensorimotor network, and increased CBF in contralesional frontal cortical and subcortical regions (putamen and thalamus). Meanwhile, the CBF in the ipsilesional insula was positively correlated, and the contralesional frontal cortical was negativity correlated, with VSTM scores. Moreover we found that stroke patients exhibited disordered connection within FCNs compared to NCs. The study suggests that the underlying imaging biomarker of VSTM impairment in patients with subcortical stroke was associated with disconnection of the frontal lobe network.

Workers' Rites: Ritual Mediations and the Tensions of New Management
Authors: Islam Gazi , Sferrazzo Roberta 
Published: March 2021

AbstractScholarship has highlighted tensions arising from the ‘new management ideology’, an attempt to infuse formal organizations with community, informality and equality. Proposals to ‘liberate’ companies have been received with a mix of scepticism and hope for their emancipatory possibilities. While the tensions arising from such proposals are known, less work examines the practices by which they are mediated in the workplace. Taking a ritual perspective, we argue that rituals’ unique capacity to mediate oppositions makes it a powerful tool in the new management toolbox. Examining a liberated enterprise initiative in a French multinational company, we analyse how rituals structure, disavow, segment or maintain organizational tensions. While rituals constituted neo‐normative controls, we also discuss the emancipatory possibilities for rituals in holding open unreconciled tensions and preventing closure. We discuss the implications for understanding neo‐normative control through rituals, outlining a future research agenda for the study of rituals in new management.

ABSTRACTBackground and PurposeCognitive impairment is a critical health problem in the elderly population. Research has shown that patients with mild cognitive impairment (MCI) may develop dementia in later years. Therefore, early identification of MCI could allow for interventions to help delay the progression of this devastating disease. Our objective in this study was to detect the early presence of MCI in elderly patients via neuroimaging and dual‐task performance.MethodsBrain MRI scans from 21 older adult volunteers, including cognitively healthy adults (HA, n = 9, age = 68‐79 years) and mild cognitively impaired (MCI, n = 12, age = 66‐92 years) were analyzed using automatic segmentation techniques. Regional volume, surface area, and thickness measures were correlated with simultaneous performance of motor and cognitive tasks (dual‐task) within a novel upper‐extremity function (UEF) test, using multivariate analysis of variance models.ResultsWe found significant associations of dual‐task performance with volume of five cortical brain regions (P ≤ .048) and thickness of 13 regions (P ≤ .043) within the frontal, temporal, and parietal lobes. There was a significant interaction effect of cognitive group on dual‐task score for the inferior temporal gyrus volume (P ≤ .034), and the inferior parietal lobule, inferior temporal gyrus, and middle temporal gyrus average thickness (P ≤ .037).ConclusionsThis study highlighted the potential of dual‐tasking and MRI morphometric changes as a simple and accurate tool for early detection of cognitive impairment among community‐dwelling older adults. The strong interaction effects of cognitive group on UEF dual‐task score suggest higher association between atrophy of these brain structures and compromised dual‐task performance among the MCI group.

AbstractBackgroundTemporomandibular disorders (TMDs) are multifactorial, and high levels of stress seem to increase symptoms. The association with exposure to violence has not been explored in adolescent populations.ObjectiveTo examine the association of self‐reported symptoms of temporomandibular pain and jaw dysfunction with child physical abuse, intimate partner violence, forced sexual intercourse, and bullying victimisation.MethodsAn epidemiological, cross‐sectional, school‐based study was conducted in Olinda, northeast Brazil. The sample comprised 2,431 adolescents aged 14–19 years. TMD‐related symptoms and exposure to violence were assessed with questions from the 3Q/TMD screener and queries on exposure to different forms of violence. Multilevel logistic regressions were conducted to evaluate how 3Q screen‐positive responses are associated with self‐reported exposure to violence.ResultsSelf‐reported TMD‐related symptoms had a prevalence of 40.5%. Significantly more females than males screened positive to all 3Q/TMD questions (p < .001). Adolescents experiencing intimate partner violence (p = .012) and bullying (p < .001) had significantly higher odds of 3Q positive responses than those who reported no exposure to violence. Significant associations of TMD‐related symptoms with forced sexual intercourse (p = .014) and with bullying (p = .007) were observed.ConclusionAdolescents with self‐reported symptoms of temporomandibular pain and jaw dysfunction were significantly more often exposed to some type of violence. The number of adolescents reporting TMD‐related symptoms increased in a dose‐response manner with the number of violence forms the individual had experienced.

Published: March 2021

AbstractBackgroundInternationally, many children and adults with intellectual disabilities are continually being supported by their family members to live within their family home. However, as a consequence of the ageing process some family members can struggle to continue to care because of their failing physical and/or mental ill‐health. This has resulted in a shift in the parameters of the relationship for some adults with intellectual disabilities with their formerly dependent role evolving into a caregiving one. This had become known as “reciprocity” or “mutual support.” Limited information exists about these “hidden carers” and what services are available to support them.AimThis article explored the lived experiences of nine adults with intellectual disabilities who provided emotional and tangible support to an ageing family member.MethodA qualitative methodology was employed using semi‐structured interviews. Nine participants with mild‐to‐moderate intellectual disabilities were interviewed within one region of the United Kingdom. The interviews were analyzed using thematic analysis.FindingsFive themes emerged within these narrative accounts: natural transition to caring; the health needs of the ageing family member; support; impact of caregiving and future planning.DiscussionThe needs of these unknown hidden carers, and also ageing family members, are immediate and urgent. Policy makers, commissioners and service providers need to examine the type of “in‐house” support provided to these new carers if they are to continue living within their family home with their ageing family member, who will also need additional support. Neglecting both cohorts will lead to greater costs to services in the longer term and seriously threaten the quality of life of people with intellectual disabilities and their family carers.

AbstractBathymodiolinae mussels are typical species in deep‐sea cold seeps and hydrothermal vents and an ideal model for investigating chemosynthetic symbiosis and the influence of high hydrostatic pressure on deep‐sea organisms. Herein, the potential influence of depressurization on DNA fragmentation and cell death in Bathymodiolinae hosts and their methanotrophic symbionts were surveyed using isobaric and unpressurized samples. As a hallmark of cell death, massive DNA fragmentation was observed in methanotrophic symbionts from unpressurized Bathymodiolinae while several endonucleases and restriction enzymes were upregulated. Additionally, genes involved in DNA repair, glucose/methane metabolism as well as two‐component regulatory system were also differentially expressed in depressurized symbionts. DNA fragmentation and programmed cell death, however, were rarely detected in the host bacteriocytes owing to the orchestrated upregulation of inhibitor of apoptosis genes and downregulation of caspase genes. Meanwhile, diverse host immune recognition receptors were promoted during depressurization, probably enabling the regain of symbionts. When the holobionts were subjected to a prolonged acclimation at atmospheric pressure, alternations in both the DNA fragmentation and the expression atlas of aforesaid genes were continuously observed in symbionts, demonstrating the persistent influence of depressurization. Contrarily, the host cells demonstrated certain tolerance against depressurization stress as expression level of some immune‐related genes returned to the basal level in isobaric samples. Altogether, the present study illustrates the distinct stress responses of Bathymodiolinae hosts and their methanotrophic symbionts against depressurization, which could provide further insight into the deep‐sea adaptation of Bathymodiolinae holobionts while highlighting the necessity of using isobaric sampling methods in deep‐sea research.

AbstractCandida auris is an emerging and drug‐resistant pathogen. Drug combination is a promising approach against such pathogens. This study was conducted to provide an overview of all the studied drug combinations against C. auris. Relevant articles reporting results of any drug/non‐drug combinations against C. auris were found by a systematic search in PubMed, Scopus and Web of Science (ISI), and in Google Scholar up to 1 October 2020. From 187 articles retrieved in the primary search, 23 met the inclusion criteria. In total, 124 different combinations including antifungal with antifungal (45), antifungal with other antimicrobials (11), antifungal with non‐antimicrobials (32), antifungal with natural compounds (25) and between natural compounds (11) have been reported. Complete or partial synergistic effects have been reported for 3 out of 45 (6.67%) combinations of two antifungal agents, 8 out of 11 (72.73%) combinations involving antifungal agents and antimicrobials, 15 out of 32 (46.88%) of combinations between antifungal agents with non‐antimicrobials, 16 out of 25 (64%) of combinations involving antifungal agents and natural compounds, and 3 out of 11 (22.27%) of combinations involving multiple natural compounds. Antagonistic interactions have been reported for 1 out of 32 (3.13%) and 8 out of 25 (32%) of combinations between antifungal drugs with non‐antimicrobials and with natural compounds, respectively. Different drugs/compounds could potentiate the activity of antifungal drugs using this approach. However, despite the availability of this promising initial data, many more studies will be required to elucidate whether favourable interactions observed in vitro might translate into tangible clinical benefits.
