Published: October 2023

Background

The novel Contour Neurovascular System (Contour) has been reported to be efficient and safe for the treatment of intracranial, wide-necked bifurcation aneurysms. Flow in the aneurysm and posterior cerebral arteries (PCAs) after Contour deployment has not been analyzed in detail yet. However, this information is crucial for predicting aneurysm treatment outcomes.

Methods

Time-resolved three-dimensional velocity maps in 14 combinations of patient-based basilar tip aneurysm models with and without Contour devices (sizes between 5 and 14 mm) were analyzed using four-dimensionsal (4D) flow MRI and numerical/image-based flow simulations. A complex virtual processing pipeline was developed to mimic the experimental shape and position of the Contour together with the simulations.

Results

On average, the Contour significantly reduced intra-aneurysmal flow velocity by 67% (mean w/ = 0.03m/s; mean w/o = 0.12m/s; p-value=0.002), and the time-averaged wall shear stress by more than 87% (mean w/ = 0.17Pa; mean w/o = 1.35Pa; p-value=0.002), as observed by numerical simulations. Furthermore, a significant reduction in flow (P<0.01) was confirmed by the neck inflow rate, kinetic energy, and inflow concentration index after Contour deployment. Notably, device size has a stronger effect on reducing flow than device positioning. However, positioning affected flow in the PCAs, while being robust in effectively reducing flow.

Conclusions

This study showed the high efficacy of the Contour device in reducing flow within aneurysms regardless of the exact position. However, we observed an effect on the flow in PCAs, which needs to be investigated further.

Authors: Lee Charlotte , Tran Theresa Tammy , Ross Joy
Published: October 2023

Objectives

Our work aims to critically review the use of anticipatory medicines in our inner-city hospice community population and whether our current practices are fit for purpose.

Methods

Retrospective audit of community palliative care patients at the end-of-life prescribed anticipatory medicines within a 3-month period. Anticipatory charts and case notes reviewed. Intervention included updating local guidelines, local teaching for medical and non-medical prescribers and sharing results nationally. Eighteen months later, reaudit was performed assessing impact.

Results

In total, 76 patients included. 75/76 (99%) were prescribed an analgesic, antiemetic, antisecretory and anxiolytic. 49/76 (64%) were administered ‘as required’ medications at home. Haloperidol was the favoured antiemetic (88%), costing our hospice ~£2000/month. Case note review highlighted prescribing and administration issues. Reaudit showed a reduction in prescriptions of antisecretory (by 57%) and antiemetic (by 50%), with a wider range of antiemetics (levomepromazine 47%, haloperidol 35%, cyclizine 14%, metoclopramide 3%) indicating individualised prescribing. Those without an antiemetic prescribed did not later require one dispensing.

Conclusion

Our work challenges the orthodoxy that an analgesic, antiemetic, antisecretory and anxiolytic medication must always be included for effective anticipatory prescribing. Antiemetics may not be universally required and individualised prescribing was cost-effective and safe at a local level. Further work evaluating the impacts of altered practice on patients, caregivers, professionals and in other community settings is required.
EXPLORING THE ROLE OF DYNAMIC ENVIRONMENTS ON THE FIRMS’ INNOVATION PERFORMANCE: MEDIATING ROLES OF TECHNOLOGY AND MARKET-SENSING CAPABILITY
Authors: HAKEEM ANAS OSAMA
Published: October 2023

Purpose: This study aims to analyse the influence of dynamic environments on technology and market-sensing capability. It also aims to examine the influence of technology and market-sensing capability on innovation performance. Besides, it aims to explore the influence of innovation performance on the organisation’s financial performance. It also aims to examine the influence of technology and market-sensing capability on the organisation’s financial performance. Design/methodology/approach: The research model was tested using a structural equation modelling design based on survey data from 183 Saudi companies from different sectors, used by software (SPSS v. 28 and SmartPLS v. 4). Findings: This study shows that dynamic environments strongly influence both financial and innovation performance. However, this study shows that innovation performance does not directly affect financial performance. Furthermore, this study shows that dynamic environments strongly influence both technology and market-sensing capability. Likewise, this study shows that both technology and market-sensing capability strongly influence financial performance. However, this study shows that both technology and market-sensing capability do not directly affect innovation performance. Originality/value: This study has demonstrated that dynamic environments will have a direct effect on the financial performance of companies by compelling them to allocate their resources more strategically and flexibly in order to adapt to the changing and unpredictable conditions of dynamic environments. Moreover, this study has also demonstrated that dynamic environments will have a direct effect on the technology and market-sensing capability of organisations. This will motivate organisations to gather and analyse information about customers, competitors, and market trends, and to use this information to identify and exploit opportunities for innovation, differentiation, and value creation for customers and stakeholders. In addition to the previous findings, this study has also shown that dynamic environments will improve the technology and market-sensing capability of organisations. This will inspire organisations to collect and analyse information about the needs, preferences, and behaviours of customers, the strategies, actions, and strengths of competitors, and the trends, opportunities, and threats of the market, and to use this information to recognize and leverage opportunities for innovation, differentiation, and value creation for customers and stakeholders. Furthermore, this capability allows organisations to use their dynamic capabilities to innovate with their resources and competencies, which are essential for gaining competitive advantage and superior performance in dynamic environments.

Published: October 2023

Tolvaptan (TOL), a vasopressin V2 receptor antagonists drug, is used to treat hyponatremia in people with heart failure. Herein, we report for the first time the electrochemical behavior of TOL and its oxidation metabolite TOL-oxo on glassy carbon and boron-doped diamond electrodes (GCE, BDDE) by cyclic voltammetry (CV). For both molecules, two-electron irreversible oxidation was observed in 0.5 M H2SO4, while single-electron irreversible oxidation occurred at pH 7.0. A sensitive and rapid electroanalytical technique for the detection of TOL has been developed, based on differential pulse voltammetry (DPV). Linearity was obtained with GCE within a concentration range between 1–1000 μM, using anodic currents appearing around 1397 mV. For BDDE, the concentration range was 8–1000 μM using anodic currents around 1490 mV.

Resilience of FEF neuronal saccade code to V4 perturbations
Authors: Shams Mohammad , Thier Peter , Lomber Stephen G. , Merrikhi Yaser
Published: October 2023

We studied neurons in the brain’s frontal eye field (FEF) to understand how these neurons predict swift eye shifts called saccades. We found that neurons with more movement-related activity were better at predicting saccades than those with sensory-related activity. Interestingly, electrical disruptions of this region strongly impacted saccade onset times but did not affect the individual neuron’s saccade predictability, consistent with models suggesting that a specific threshold in neural activity triggers the saccade.

Authors: Christova Peka , Georgopoulos Apostolos P.
Published: October 2023

We report mixed effects of age on subcortical grey matter volume (GMV) during lifespan ( n = 2458, 5-90 yr old, 1113 male, 1345 female). Striatal and cerebellar GMVs decreased linearly with age, more steeply in males. In contrast, GMVs of the amygdala, pallidum, thalamus, ventral diencephalon, and brainstem changed in a quadratic fashion, increasing first and decreasing afterward, with males peaking earlier than females in all regions but the brainstem where they peaked at nearly the same time.
Optimizing the Fermentation Conditions of Cudrania tricuspidata Fruit Using Bacillus amyloliquefaciens for Anti‐Inflammatory Activity and GC‐MS‐Based Volatile Component Characteristics
Authors: Ha Si Young , Jung Ji Young , Kim Hyeon Cheol , Yang Jae-Kyung
Published: October 2023

The aim of this study is to optimize the performance conditions used for maximum anti‐inflammatory activity and to clarify in vitroanti‐inflammatory properties of fermented C. tricuspidata fruit. Based on the single‐factor experiment and Box–Behnken design, the optimized fermentation conditions of C. tricuspidata fruit for maximum anti‐inflammatory activity were 3.8 d fermentation period, 8.4% (v/w) inoculation concentration, and 29.2°C fermentation temperature. Under optimal conditions, anti‐inflammatory activity‐based nitric oxide of fermented C. tricuspidata fruit reached 93.9%. Moreover, this study provides a theoretical basis and experimental data containing β‐hexosaminidase and reactive oxygen species for the medical use and industrialization of C. tricuspidata fruit fermentation. Interestingly, the results of GC‐MS analysis confirmed that fermented C. tricuspidata fruits detect volatile components different from unfermented C. tricuspidata fruits. We suggested that this volatile component may have been involved in the anti‐inflammatory reaction, but scientific verification of this is needed later. Therefore, an in‐depth study of volatile components detected from fermented C. tricuspidata fruits will need to be conducted later.

Published: October 2023

Introduction. In Ethiopia, traditional medicine has significantly contributed to the treatment of public health conditions. However, when contrasted with the ethnic diversity of Ethiopians, the number of medicinal plants that have been documented remains limited. As a result, the study aimed to record the medicinal plants used in the Zuway Dugda district communities. Methodology. An ethnobotanical study of medicinal plants used by local people of Zuway Dugda district was carried out from February 2020 to November 2020. Semistructured interviews, a market survey, field observations, and group discussions were used to gather pertinent data. One hundred informants (83 males and 17 females) provided data. 76 informants were chosen at random, while 24 key informants were chosen on the basis of recommendations from local elders. Data were analyzed using descriptive statistics, preference ranking, paired comparison, and direct matrix ranking. Results. A total of 73 plant species, representing 62 genera and 40 families, were collected and identified. Asteraceae, Fabaceae, and Solanaceae had the most species, with each family having 6 (8.22%) species, followed by Euphorbiaceae, which had 4 (5.48%) species. The wild harvest of approximately 49 medicinal plants (or 67.12%) was used. 31 plant species, or 42.47% herbs, were found to be the most commonly used life forms. The most frequently used plant parts were reported to be the leaves, which accounted for 55 species (41.35%) and then the roots 25(18.80%). Headache, toothache, depression, febrile illness, and fever had the lowest ICF values (0.33), while snake bite‐related issues had the highest ICF values (0.93). The results of the preference ranking indicated that locals prefer to treat wounds with Asparagus africanus Lam. The community used Cordia africana Lam. the most, according to direct matrix ranking. Conclusions. It is essential to combine indigenous knowledge with scientific methods in order to extract the most benefit from medicinal plants. The results of the ICF and preference ranking could be used as a prelude to this. Since A. africanus was found to be the most effective wound‐healing medicinal plant in the current study, further phytochemical and pharmacological research is recommended.
Optimization of Switching Control and Microgrid Energy Management System with Alternate Arm Converter Based on Bacterial Foraging Algorithm
Authors: Rama S. T. , Rajini V.
Published: October 2023

The global demand of electrical power has increased enormously due to various reasons such as fast-changing and challenging technologies, climatic change, economic growth, and lifestyle of mankind. Due to global warming issues and the depletion of conventional sources of power generation, the utilization of renewable energy sources has drastically increased. So, many challenges exist in integrating the microgrid with AC grid and load. The alternative arm converter (AAC) is among the most innovative converter topologies used in high voltage direct current (HVDC) applications. This research work presents a new control strategy to generate pulses to trigger the switches in the AAC in a proper sequence to obtain a smooth output waveform. The AAC output is controlled by implementing various controllers such as the proportional-integral-derivative (PID) controller, fractional order PID (FOPID) controller, and FOPID controller tuned by metaheuristic algorithm-bacterial foraging optimization technique (BFOT). Also, a comparative analysis is performed based on the spectral analysis of the output voltage obtained. In comparison to other controllers, the FOPID controller optimized by the bacterial foraging optimization technique (BFOT) produced the least total harmonic distortion (THD) of the AAC output voltage. In addition, this paper also discusses about the performance and analysis on the design of an energy management system (EMS) to optimally utilize the energy sources such as PV system, wind system, and battery based on their availability which feed the AAC. The energy management system controls the entire integrated system in association with an integrated CUK-SEPIC converter to fulfil the load demand at the point of common coupling, either from the microgrid or the AC grid. A nine-level AAC model is designed integrating the microgrid, grid, and industrial loads with an energy management system using MATLAB/Simulink. The performance parameters of the entire model are analysed at every stage to provide stabilized output to meet the load demand.
The Histone Deacetylase Inhibitory Potential of Chicken Egg Yolk Fat and Their Fatty Acid Composition
Authors: Ediriweera Meran Keshawa
Published: October 2023

Histone deacetylation is a key biochemical event associated with transcriptional regulation. Histone deacetylases (HDACs) mediate the deacetylation of histones. Fatty acids have been reported to function as histone deacetylase inhibitors (HDACi). The present instigation reports the HDAC inhibitory activity of egg yolks and egg yolk-derived fat of country and farm chicken for the first time. Egg yolks and fatty acids derived from both country (CCEF) and farm chicken (FCEF) demonstrated significant HDAC enzyme activity inhibition. Furthermore, egg yolks, CCEF, and FCEF exhibited DPPH free radical scavenging effects. The analysis of fatty acid profiles revealed varying degrees of saturated, mono-, and polyunsaturated fatty acids in the egg yolks. Palmitic acid (C16 : 0) was found to be the most abundant saturated fatty acid in both CCEF and FCEF. Among the monounsaturated fatty acids, oleic acid (C18 : 1) was the most abundant in both CCEF and FCEF. In terms of polyunsaturated fatty acids, a significant difference was observed in the content of linoleic acid (C18 : 2), an omega-6 fatty acid, and docosahexaenoic acid (C22 : 6), an omega-3 fatty acid, between CCEF and FCEF. These findings present exciting prospects for the development of histone deacetylase inhibitors based on egg yolk fat.
Physicomechanical Characterization of a Novel Resin-Modified Glass Ionomer Luting Cement Functionalized with a Phosphate Functional Monomer
Authors: Khalil Rabeia J. , Al-Shamma Abdulla M. W.
Published: October 2023

Background. Resin-modified glass ionomer cements (RMGICs) are characterized by their ability to chemically bond with the tooth structure and their fluoride release, making them commonly used to retain indirect restorations. However, inferior mechanical properties and solubility (SO) are their main drawbacks compared to the most recent resin-based cement. Aim of the Study. Formulate a novel brand of experimental RMGIC (eRMGIC), based on RMGIC by incorporating 2-(methacryloxy) ethyl phosphate (2-MEP), an organophosphorus monomer with the potential to enhance mechanical properties along with low SO. Materials and Methods. eRMGICs were prepared by the inclusion of 2-MEP monomer with different weight percentages (0–40 wt%) into the RMGIC’s liquid (Fuji PLUS, GC. Corp.), then their compressive strength (CS), flexural strength (FS), film thickness (FT), setting time (ST), SO, and water sorption were examined and compared to the conventional RMGIC. Furthermore, a scanning electron microscope analyzed their surface homogeneity and integrity. Shapiro–Wilk test of normality was used to analyze data, one-way analysis of variance, Dunnett T3, and Tukey’s honest significant difference post-hoc tests. Results. After 28 days and 180 days of storage, the values of CS of the eRMGICs were significantly higher. However, after 24 hr of storage, the values were comparable to the control group. The FS results showed a double-fold increase in different concentrations of eRMGICs through all the time intervals (

0.001

) compared to conventional RMGIC. Furthermore, the inclusion of 2-MEP increased water uptake and decreased SO. The FT of experimental eRMGICs cement showed a statistically significant increase with increasing 2-MEP concentration. However, it was within the specification given by ISO 9917-1:2007. There was a decrease in the ST of eRMGICs compared to control cement; however, it was within the specification given by ISO 9917-2:2017. Conclusions. 2-MEP monomer showed encouraging results and could be used in producing new (eRMGICs) with enhanced physicomechanical properties, which can increase the longevity of cement and improve its ability to resist occlusal stresses without fracture.

Published: October 2023

Late-onset combined immunodeficiency (LOCID), considered now a subset of common variable immunodeficiency (CVID) disorders, is characterized by a predominantly T-cell immune defect. LOCID has a distinct phenotype from CVID with a greater risk of lymphoproliferative complications. As compared to the CVID cohort, LOCID patients also have increased rates of splenomegaly and granulomatous disease. We report a case of central nervous system (CNS) T-cell lymphoma in a 67-year-old male as the presenting manifestation of LOCID. The patient achieved a complete response to therapy after 4 cycles of MATRix (methotrexate, cytarabine, and thiotepa) and 2 cycles of ICE (etoposide, carboplatin, and ifosfamide) chemotherapy followed by CNS-directed autologous stem cell transplantation. Intravenous immunoglobulin replacement was commenced to address the underlying immunodeficiency. Pulmonary lesions consistent with a diagnosis of granulomatous and lymphocytic interstitial lung disease (GLILD) were identified as a second noninfectious complication of LOCID. The pulmonary lesions resolved after chemotherapy and immunoglobulin replacement. The patient remains well with no evidence of disease recurrence now more than 18 months after completion of therapy. This is the first reported case of T-cell lymphoma in an adult patient with LOCID. Further study is needed to elucidate the mechanisms of transformation of B- or T-cells to lymphoproliferation in primary immunodeficiency patients as well as research to inform evidence-based therapeutic strategies for this challenging cohort of patients.

Published: October 2023

Introduction: Early detection of dysphagia risk, initiating rehabilitation, and resumption of appropriate diet based on swallowing function is important during deep neck infection (DNI) control. This study aimed to evaluate the extent of cervical abscess development, particularly in the deep neck space, and its relationship to postoperative swallowing function. Methods: A retrospective chart review was performed for all DNI cases treated between April 2015 and April 2021. Deep neck spaces were divided into categories based on computed tomography findings. Functional Oral Intake Scale (FOIS) scores of 4 or higher was defined as normal or slight swallowing disorder and 3 or lower as dysphagia. Results: Seventeen cases were included in the analysis. Based on FOIS, 14 cases were classified into the dysphagia group at 2 weeks after surgery, 11 cases at 4 weeks, and 8 cases at 8 weeks. There was no significant difference between the location of the abscess and dysphagia at 2 weeks after surgery. Patients with anterior cervical space abscess significantly increased dysphagia 4 weeks (p = 0.018) and 8 weeks (p = 0.036) after surgery. Conclusion: Abscess formation in the anterior cervical space may be associated with prolonged dysphagia after treatment due to inflammation and scarring of the muscles associated with swallowing.

Published: October 2023

Introduction: Chronic atrophic gastritis may contribute to gastric polyps (GP) phenotype in familial adenomatous polyposis (FAP). Considering the high prevalence of Helicobacter pylori (HP) infection in Portugal, we aim to characterize GP in a series of Portuguese patients. Methods: In a retrospectively selected series of 53 FAP patients, clinical data and histopathological features of GP and background gastric mucosa were studied. SPSS (27.0) was used for statistical analysis. Results: Thirteen patients (24.5%) developed fundic gland polyps (FGP), seven (13.2%) gastric adenomas (GA), and ten (18.9%) both FGP and GA. Out of 100 GP, four were hyperplastic polyps, 58 FGP (24 with dysplasia), 35 intestinal-type GA (intGA), and three foveolar-type GA (fovGA). IntGA were larger (60% >7 mm, p = 0.03), occurred predominantly in the distal stomach (66.7%, p = 0.024), in patients harboring gastric intestinal metaplasia (IM) (86.7%, p < 0.001), and duodenal adenomas (86.7%, p < 0.001). Conclusion: This is the first Western series showing high prevalence of intGA in FAP patients, comparable to Asian cohorts. HP infection and chronic atrophic gastritis/intestinal metaplasia are likely responsible for this difference, with risk of neoplastic transformation and management implications. Biopsy/excision of GP >7 mm in the distal stomach and in patients harboring gastric intestinal metaplasia/duodenal adenomas should be considered.

Published: October 2023

Este artigo está centrado nas análises comparadas de obras de Iole de Freitas (Belo Horizonte, 1945) e Olafur Eliasson (Copenhague, 1967) que, em momentos distintos, foram situadas em um dos pátios internos do edifício da Pinacoteca do Estado de São Paulo. Esse espaço, originalmente projetado por Ramos de Azevedo (São Paulo, 1851 – Santos, 1928), sofreu importantes alterações após a reestruturação concebida pelo arquiteto modernista Paulo Mendes da Rocha (Vitória, 1928 – São Paulo, 2021), junto a seus colaboradores, finalizada em 1998. Com o intuito de delinear similaridades e diferenças entre os trabalhos dos artistas, realizamos exercícios de espelhamentos e justaposições entre as obras e o espaço, investigando, por fim, de que modo a sobreposição de conceitos e imagens reflete na relação composta entre instalação artística e arquitetura.
Reconsidering David Tracy’s Public Theology in a Digital Age
Authors: Okey Stephen
Published: October 2023

While public theology initially developed amid concerns about secularization, its continued flourishing requires attention to the digital. Shaped especially by mediatization, digital intimacy, and accessibility issues, the digital sphere impacts both the idea of ‘public-ness’ and the practice of theology. Building on the work of David Tracy, this article offers four possible approaches in light of his methodological connection between publics and theological subdisciplines: the digital is only an extension of existing forms of mediation, the digital is a feature of society and practical theology, the digital is a new public and needs a new subdiscipline, or the digital is a new context for the various publics and thus requires a contextual theology.
A Journey without Maps
Authors: Rae Simon
Published: October 2023

The challenge of finding a Protestant public theology appropriate for a pluralist, newly independent, Muslim majority nation was taken up initially by a mixed group of lay and ordained theologians, among them T. B. Simatupang, a recently retired lieutenant-general, still in his late thirties. This study links Simatupang’s experience as a soldier-diplomat and strategic planner in Indonesia’s struggle for independence to the objectives and values he promoted and endeavoured to safeguard in his second career as an ecumenical strategist and mentor. Some attention is given to more recent criticism and the argument that a less confrontational Christian stance toward politically active Islam is called for in today’s era of interfaith conversations.
Wissenschaft des Judentums in Eastern Europe: The Origins of Hevrat Mekitze Nirdamim
Authors: Meir Jonatan
Published: October 2023

The history of the Mekize Nirdamim (“rousers of those who slumber”) society is quite peculiar. When looking at its activities, one can speak of three distinct periods: a first period in Eastern Prussia under the leadership of Eliezer Lippman Zilberman, owner of the Ha-Maggid newspaper, a period that extended for ten years and whose success was largely located in Eastern Europe; a second period in Berlin under the domineering leadership of Abraham Berliner, a period, centered in Western Europe, that extended for over twenty years; and a third period in the Land of Israel, led initially by David Yellin, Simcha Assaf, and S.Y. Agnon. I will introduce each and focus on several points relating to the relationship between East and West, and Mekize Nirdamim’s ties to several other projects that threatened to swallow it alive. In doing so, I will draw attention to the society’s roots in Eastern Europe.

Published: October 2023

A new fungal species found on decaying wood in a mangrove habitat is described. The analysis of combined LSU, ITS, and rpb2 sequence data revealed that it belongs to the family Paradictyoarthriniaceae (Pleosporales). Maximum likelihood and Bayesian analyses were used to determine the taxon’s phylogenetic affinities. The novel species is typical of Paradictyoarthrinium in its gregarious, black, powdery colonies with macronematous conidiophores and unevenly dictyoseptate, muriform, green to brown conidia. The new taxon is compared to other Paradictyoarthrinium species, and a detailed morphological description and illustration are provided.
Predictability of Rainfall over Equatorial East Africa in the ECMWF Ensemble Reforecasts on Short- to Medium-Range Time Scales
Authors: Ageet Simon , Fink Andreas H. , Maranan Marlon , Schulz Benedikt
Published: October 2023

Despite the enormous potential of precipitation forecasts to save lives and property in Africa, low skill has limited their uptake. To assess the skill and improve the performance of the forecast, validation and postprocessing should continuously be carried out. Here, we evaluate the quality of reforecasts from the European Centre for Medium-Range Weather Forecasts over equatorial East Africa (EEA) against satellite and rain gauge observations for the period 2001–18. The 24-h rainfall accumulations are analyzed from short- to medium-range time scales. Additionally, 48- and 120-h rainfall accumulations were also assessed. The skill was assessed using an extended probabilistic climatology (EPC) derived from the observations. Results show that the reforecasts overestimate rainfall, especially during the rainy seasons and over high-altitude areas. However, there is potential of skill in the raw forecasts up to 14-day lead time. There is an improvement of up to 30% in the Brier score/continuous ranked probability score relative to EPC in most areas, especially the higher-altitude regions, decreasing with lead time. Aggregating the reforecasts enhances the skill further, likely due to a reduction in timing mismatches. However, for some regions of the study domain, the predictive performance is worse than EPC, mainly due to biases. Postprocessing the reforecasts using isotonic distributional regression considerably improves skill, increasing the number of grid points with positive Brier skill score (continuous ranked probability skill score) by an average of 81% (91%) for lead times 1–14 days ahead. Overall, the study highlights the potential of the reforecasts, the spatiotemporal variation in skill, and the benefit of postprocessing in EEA.

Hybrid polymer composites have been proven to be an alternative to the conventional ones that use only one filler in the polymeric matrix. In this study, the effect of the addition of cotton linter fibers (CLF) and/or montmorillonite (MMT) nanoclay as fillers in recycled polyethylene (PER) composites was evaluated with and without using maleic anhydride grafted polyethylene (PE– g–MAH) as an interfacial compatibilizing agent. The presence of titanium dioxide (TiO2) used as a color additive was confirmed by the characterizations of PER. It was found that the rheological, morphological, and mechanical properties of PER were significantly altered by adding fillers, owing to the difference in shape and composition of these fillers. The results of the characterizations showed evidence of double or triple interaction with the reactive groups of PE– g–MAH and the hydroxyl (–OH) present in CLF, MMT, and TiO2.

Published: October 2023

This article aims to contribute to the research-practice gap in bereavement care by exploring Research Circles as a collaborative approach to implementation of research-based knowledge into bereavement care. Particularly the article discusses key dimensions for translating research concerning bereaved after drug-related deaths into practice-relevant knowledge, as a first step of implementation. This co-created knowledge translation took place in the first phase of a Research Circle including bereaved mothers, practitioners and researchers. Data were collected via semi-structured interviews with Research Circle participants and field notes. Data were analyzed using reflexive thematic analysis. Results showed two key dimensions with the Research Circle approach influencing the translation process: (1) multiple and long-lasting arenas for translation: (2) multiple stakeholders and perspectives. Research Circles appear to be a promising framework for translating research-based knowledge in bereavement care, but there are some barriers to fully realizing the democratic ideal that underlines the Research Circle framework.

Previous studies have indicated a relationship between perfectionism and social anxiety symptoms, but the mechanisms between these concepts are not well-defined yet. This study focused on the mediator role of self-compassion in the relationship between maladaptive perfectionism and social anxiety symptoms controlling self-esteem. It is hypothesized that maladaptive perfectionism would be related to lower levels of self-compassion and lower levels of self-compassion related to greater social anxiety symptoms controlling self-esteem. The sample consisted of 389 university students who completed a battery of instruments, including measures of The Liebowitz Social Anxiety Scale (LSAS), The Big Three Perfectionism Scale (BTPS), The Self-Compassion Scale (SCS), and The Rosenberg Self-Esteem Scale (RSES). Simple mediation analyses with bootstrapping demonstrated that self-compassion has a significant mediator role in the relationship between maladaptive perfectionism and social anxiety when self-esteem is not included in the model. However, results also revealed that the indirect effect of self-compassion is no longer significant when self-esteem is included in the model as a covariate. Findings suggest that self-compassion has no mediator role independent from self-esteem in the context of perfectionism and social anxiety.
A word about . . . Violence in a pluralistic age: Constraints and opportunities for Christians
Authors: Oladipo Caleb O.
Published: October 2023

The challenges presented by the current global culture of violence are baffling. Humanity faces these unprecedented challenges that have origins in sacred texts containing violent events. “Spiritualizing” these events is not the solution to dealing with the problems they present. Christians should be prepared to doubt the texts that promote violence as a part of faithfulness to God. This article suggests the opposite of faith is not only doubt, but also fear. Christians demonstrate a cheap relationship with sacred texts when they fail to challenge traditional interpretations. A more mature approach is to embrace alternative, if unfamiliar, interpretations of sacred texts rather than hold on to orthodoxy that is beloved but unloving. Christians should see the texts that seem to justify violence or encourage war as a message requiring humanity to struggle against such violence to transform the world around them nonviolently. The Church of the twenty-first century has optimal opportunity for building harmonious relationships with people of other faiths, which will require a multifaceted approach to understanding God in a pluralistic age.
Do we need a co-pilot in the operating theatre? A cross-sectional study on surgeons’ perceptions
Authors: Taribagil Priyal , Liu Timing , Bhattacharya Vish , Taribagil Sanjay
Published: October 2023

Objective

The aim of this original study was to investigate general surgeons’ perceptions on the role of dual surgeon operating for high-risk, elective complex surgical procedures.

Material and Methods

A 21-part cross-sectional online survey was self-completed by 85 general surgeons across hospitals in the UK. The survey assessed the perception of dual surgeon operating on patient morbidity and mortality, surgeons’ burnout rates, complaints, patient waiting times and overall trainee experience. Statistical analysis was performed using R version 3.6.1.

Results

Overall 78.8% believed that dual surgeon operating could help to overcome these human factors. Sub-analysis includes improve surgeon fatigue (89.4%), improve confidence (83.5%), improve decision-making (76.5%), minimise technical error (69.4%), improve communication, team work and leadership skills (65.9%). 65.9% believed it would reduce surgeons’ burnout. There was a statistically significant relationship between the participants believing it would reduce surgeons’ burnout and those who felt it would reduce complaints, Chi-squared(4) = [30.8], p = [0.00000342]. A statistically significant relationship was noted between participants believing it would reduce surgeons’ burnout and those who felt it would reduce patient mortality/morbidity, Chi-squared(4) = [19.9], p = [0.000517].

Conclusion

The survey has highlighted positive surgeons’ perceptions regarding dual surgeon operating.
Study on modified VAc-VeoVa10 latex prepared by soap-free emulsion polymerization
Authors: Gong Zheqing , Chen Lijun
Published: October 2023

Modified latex is prepared via the soap-free emulsion polymerization of ethyl acetate (VAc) and vinyl versatate (VeoVa10). DFHMA is used as modified monomers. The composite surfactants of SR-10 and ANPEO-10 are used as the composite emulsifiers. The polymerization is initiated by potassium sulfate (KPS). The structure of latex film was characterized by Fourier transform infrared spectroscopy (FTIR). The latex films were tested by thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and contact angle (CA) determinator. The particle size of the latex emulsion particle size is determined by the Zetatrac dynamic light scatter. Results show that the optimum condition of preparing the modified latex can be obtained, i.e. the amount of emulsifier is 4.0%; the mass ratio of SR-10 to ANPEO-10 is 1:1; the amount of initiator is 0.5%; the mass ratio ofVAc to VeoVa10 is 1:1; the amount of DFHMA is 5.0%. The appearance of the latex is blue and translucent with a small particle size. The conversion rate is more than 98%. Compared with the conventional latex, the hydrophobicity and heat resistance of the film have been improved. Moreover, the latex has good chemical stability and mechanical stability.
Will they rise again? Four scenarios for the future of trade unions
Authors: Visser Jelle
Published: October 2023

With rising consumer prices, tight labour markets, a resurgence in labour militancy, and a new post-Covid appreciation of the role of government and market regulation, the conditions for renewed union growth seem favourable. But unions have to come from far. Across the OECD, unions have lost members and power, young people increasingly stay away from unions and labour markets have thoroughly changed from what they were. How likely, then, is a new era for trade unions? This article explores four scenarios for the future of trade unions – marginalization, dualism, substitution and revitalization – each grounded in a few assumptions about the environment and behaviour of unions. Drawing on data and research from 12 OECD member states, the article explores middle range theories for each scenario and weighs arguments pro and contra its likelihood. It concludes with a set of critical propositions about the future of trade unions and research about the future.
For the Betterment of All: Motivating Factors With Significant Impact on Annual Giving Practices in Independent Schools
Authors: Reardon Laura
Published: October 2023

In an increasingly individualistic society in which the economic forecast has been uncertain for the past several years, independent schools have struggled to understand donors’ motivations for giving. In addition, schools continually examine the way their annual giving campaigns articulate how donors’ gifts align with the schools’ missions and future strategic goals. This case study aims to form an understanding of giving practices for independent schools. Because annual giving is central to the financial sustainability and success of a school, this study’s aim is to fully examine the extent to which school constituents (parents, grandparents, alumni, faculty members, parents of alumni, administration, and students) are involved in the annual giving process and aware of its impact. There is a distinct disparity in the outcome of fundraising efforts of long-standing independent schools and institutions with existing endowments and newer independent schools. The question becomes, How do the latter schools better educate their constituents about the importance of the annual fund? Using qualitative data elicited from survey and interview methods, this study examines the motivating factors that have a significant impact on annual giving practices.
Drawing Data Together: Inscriptions, Asylum, and Scripts of Security
Authors: Perret Sarah , Aradau Claudia
Published: October 2023

Data have become a vital device of border governance and security. Recent scholarship on the datafication of borders and migration at the intersection of science and technology studies and critical security studies has privileged concepts attuned to messiness, contingency, and friction such as data assemblages and infrastructures. This paper proposes to revisit and expand the analytical vocabulary of script analysis to understand what comes to count as data, what forms of data come to matter and how “drawing data together” reconfigures power and agency at Europe’s borders. Empirically, we analyze controversies about the practices of asylum decision-making and age assessment in Greece. We show that agency of “users” is unequally distributed through anticipations of subscription and dis-inscription, while asylum seekers are conscripted within security scripts that restrict their agency. Moreover, as a multiplicity of inscriptions are produced, migrants’ claims can be disqualified through circumscriptions of data and ascriptions of expertise.
