Psychological Reactions of Lebanese Nurses to Workplace Violence in Critical Care Units

Introduction Workplace violence (WPV) is a growing concern that constitutes a major threat to occupational health and safety, thereby comprising a priority issue for policymakers. Given the increasing prevalence of chronic diseases and comorbidities among the Lebanese population, nurses working in critical care settings encounter intense workloads and high-risk interactions, potentially increasing the risk of WPV. Objectives This study aimed to investigate the traumatic and psychological reactions of Lebanese critical nurses who have been exposed to WPV, and the risk factors for depression and anxiety. Methods The study utilized a cross-sectional descriptive correlational design; 112 critical care nurses from diverse departments took part in this study during the period of June to July 2021. Results A positive, significant correlation between WPV exposure and self-reported anxiety was observed, p = . 03 with high levels of WPV, especially among patients and their families. Although verbal abuse was found to be more prevalent among critical care nurses in Lebanon compared to physical and sexual violence, the severity of the situation and its impact on the nurses’ mental health and well-being cannot be ignored. Conclusions WPV for critical care nurses is a serious issue that needs to be considered. Policy-makers should develop the politics of regulating the nursing profession, especially for critical care nurses in Lebanon.
Canalization of subwavelength images by electromagnetic crystals

An original regime of operation for flat superlenses formed by electromagnetic crystals is proposed. This regime does not involve negative refraction and amplification of evanescent waves in contrast to the perfect lenses formed by left-handed media. The sub-wavelength spatial spectrum of a source is canalized by the eigenmodes of the crystal having the same longitudinal components of wave vector and group velocities directed across the slab. The regime is implemented at low frequencies with respect to the crystal period by using capacitively loaded wire media. The resolution of λ/6 is demonstrated. The thickness of the lens is not related with the distance to the source and the lens can be made thick enough.
Metabolomic Investigation of Blood and Urinary Amino Acids and Derivatives in Patients with Type 2 Diabetes Mellitus and Early Diabetic Kidney Disease

Diabetic kidney disease (DKD) is the leading cause of end-stage renal disease; however, few biomarkers of its early identification are available. The aim of the study was to assess new biomarkers in the early stages of DKD in type 2 diabetes mellitus (DM) patients. This cross-sectional pilot study performed an integrated metabolomic profiling of blood and urine in 90 patients with type 2 DM, classified into three subgroups according to albuminuria stage from P1 to P3 (30 normo-, 30 micro-, and 30 macroalbuminuric) and 20 healthy controls using high-performance liquid chromatography and mass spectrometry (UPLC-QTOF-ESI* MS). From a large cohort of separated and identified molecules, 33 and 39 amino acids and derivatives from serum and urine, respectively, were selected for statistical analysis using Metaboanalyst 5.0. online software. The multivariate and univariate algorithms confirmed the relevance of some amino acids and derivatives as biomarkers that are responsible for the discrimination between healthy controls and DKD patients. Serum molecules such as tiglylglycine, methoxytryptophan, serotonin sulfate, 5-hydroxy lysine, taurine, kynurenic acid, and tyrosine were found to be more significant in the discrimination between group C and subgroups P1–P2–P3. In urine, o-phosphothreonine, aspartic acid, 5-hydroxy lysine, uric acid, methoxytryptophan, were among the most relevant metabolites in the discrimination between group C and DKD group, as well between subgroups P1–P2–P3. The identification of these potential biomarkers may indicate their involvement in the early DKD and 2DM progression, reflecting kidney injury at specific sites along the nephron, even in the early stages of DKD.
Leadership, Communication, and Job Satisfaction for Employee Engagement and Sustainability of Family Businesses in Latin America

This research focuses on the determinants of employee engagement in family businesses in Peru. The study is based on previous research that showed the importance of organisational culture, leadership, and human resource management practices to achieve effective business performance. The methodological strategy was to conduct a qualitative, quantitative, and documentary analysis research. The study found that participatory and authentic leadership styles, effective communication, and job satisfaction were key factors to retain talent in two family businesses and small to medium-sized enterprises in Peru. These factors can enhance employee engagement, which is critical for the success of family businesses. The results suggest that Peruvian family businesses can improve their sustainability and contribute positively to the economic growth of the country by utilising different measures. They can prioritise leadership, communication, and job satisfaction; offer opportunities for employee development and growth; provide competitive compensation packages; and create a positive work environment. The findings have implications for family businesses in emerging markets as well as for businesses operating in consolidated markets.
Optimal Reactive Power Dispatch Using Improved Pseudo-gradient Search Particle Swarm Optimization

Abstract This article proposes an improved pseudo-gradient search-particle swarm optimization (IPG-PSO) approach for solving the optimal reactive power dispatch (ORPD) problem. This ORPD problem is to determine optimal control variables, such as generator bus voltages, settings of shunt VAR compensators, and tap settings of on-load tap change (OLTC) transformers, for minimizing the real power loss, voltage deviation, and voltage stability index satisfying power balance equations and generator and network operating limit constraints. The proposed method is an improved PSO using a linearly decreasing chaotic inertia weight factor and guided by a pseudo-gradient search, which determines an appropriate direction of particles toward a global optimal solution. The proposed IPG-PSO method is used to minimize three different single-objective functions, including real power loss, voltage deviation, and voltage stability index. Test results on the IEEE 30-bus and 118-bus systems indicate that the proposed IPG-PSO method renders a higher solution quality and faster computing time than other methods. Accordingly, the proposed IPG-PSO for solving ORPD problem is potentially viable for online implementation.
Metabolic and proteostatic differences in quiescent and active neural stem cells

Adult neural stem cells are neurogenesis progenitor cells that play an important role in neurogenesis. Therefore, neural regeneration may be a promising target for treatment of many neurological illnesses. The regenerative capacity of adult neural stem cells can be characterized by two states: quiescent and active. Quiescent adult neural stem cells are more stable and guarantee the quantity and quality of the adult neural stem cell pool. Active adult neural stem cells are characterized by rapid proliferation and differentiation into neurons which allow for integration into neural circuits. This review focuses on differences between quiescent and active adult neural stem cells in nutrition metabolism and protein homeostasis. Furthermore, we discuss the physiological significance and underlying advantages of these differences. Due to the limited number of adult neural stem cells studies, we referred to studies of embryonic adult neural stem cells or non-mammalian adult neural stem cells to evaluate specific mechanisms.
ON THE GRADED RING OF THETA-CONSTANTS.*

Introduction. Let g be a positive integer and let T be a complex symmetric matrix of degree g with a positive-definite imaginary part. The set of such matrices forms a convex open subset of the 1 * g (g + 1) -dimensional complex vector space and (as a complex manifold) it is called the Siegel upper-half plane of degree (or "genus") g. A standard notation for this is Sg. Observe that 25, is the upper-half of the ordinary complex plane. We know that the group Sp (g, R) operates transitively on (Big as
Experiences of Sex Workers in Chicago during COVID-19: A Qualitative Study

COVID-19 exacerbated health disparities, financial insecurity, and occupational safety for many within marginalized populations. This study, which took place between 2019 and 2022, aimed to explore the way in which sex workers (n = 36) in Chicago were impacted by COVID-19. We analyzed the transcripts of 36 individual interviews with a diverse group of sex workers using thematic analysis. Five general themes emerged regarding the detrimental impact of COVID-19 on sex workers: (1) the impact of COVID-19 on physical health; (2) the economic impact of COVID-19; (3) the impact of COVID-19 on safety; (4) the impact of COVID-19 on mental health; and (5) adaptive strategies for working during COVID-19. Participants reported that their physical and mental health, economic stability, and safety worsened due to COVID-19 and that adaptive strategies did not serve to improve working conditions. Findings highlight the ways in which sex workers are particularly vulnerable during a public health crisis, such as COVID-19. In response to these findings, targeted resources, an increased access to funding, community-empowered interventions and policy changes are needed to protect the health and safety of sex workers in Chicago.
GM1 Ganglioside as a Disease-Modifying Therapeutic for Parkinson’s Disease: A Multi-Functional Glycosphingolipid That Targets Multiple Parkinson’s Disease-Relevant Pathogenic Mechanisms

Parkinson’s disease (PD) is a progressive neurodegenerative disorder affecting millions of patients worldwide. Many therapeutics are available for treating PD symptoms but there is no disease-modifying therapeutic that has been unequivocally shown to slow or stop the progression of the disease. There are several factors contributing to the failure of many putative disease-modifying agents in clinical trials and these include the choice of patients and clinical trial designs for disease modification trials. Perhaps more important, however, is the choice of therapeutic, which for the most part, has not taken into account the multiple and complex pathogenic mechanisms and processes involved in PD. This paper discusses some of the factors contributing to the lack of success in PD disease-modification trials, which have mostly investigated therapeutics with a singular mechanism of action directed at one of the many PD pathogenic processes, and suggests that an alternative strategy for success may be to employ multi-functional therapeutics that target multiple PD-relevant pathogenic mechanisms. Evidence is presented that the multi-functional glycosphingolipid GM1 ganglioside may be just such a therapeutic.
Feasibility of Mindfulness for Burn Survivors and Parents of Children with Burns

Burn survivors, spouses, and parents of children with burns may experience psychological distress for a prolonged period. Mindfulness-Based Stress Reduction (MBSR) is an intervention that can improve psychological well-being. This study aimed to examine the effectiveness of an MBSR group intervention in a convenience sample. An MBSR group intervention was conducted for burn survivors (n = 8) and parents of children with burns (n = 9), each comprising eight sessions. The participants completed the Beck Depression Inventory-II-NL, PTSS Checklist DSM-5, Five Facet Mindfulness Questionnaire-Short Form, Self-Compassion Scale-Short form, and evaluation questions at baseline, immediately after, and three months post-intervention. All participants completed the intervention. The intervention was rated very useful (M = 8.8), and the participants were very satisfied (M = 8.8). The highest effect was observed in the parents’ group on mindfulness skills and self-compassion. For both groups, there was an increase in personal goal scores immediately after the intervention. Qualitative data show that the participants in both groups experienced more inner peace, more awareness of thoughts and emotions, and more self-compassion. This exploratory study suggests that a mindfulness intervention is feasible and can be effective in improving mindfulness skills and self-compassion, particularly in parents of children with burns.
Cold‐conveyor‐belt jet, sting jet and slantwise circulations in idealized simulations of extratropical cyclones

The present study investigates the formation of sting‐jet cyclones using an idealized configuration of a high‐resolution mesoscale numerical model. The initial set‐up is composed of axisymmetric finite‐amplitude synoptic‐scale cyclones added to a baroclinic zonal jet. When the surface cyclone is initialized on the warm‐air side of the zonal jet, a strong bent‐back warm front forms, which is a favourable condition for sting jets. A rather high vertical resolution of about 200 m in the lower troposphere is required to obtain well‐formed slantwise circulations near the cloud head and to make the distinction between cold‐conveyor‐belt jet and sting jet. In contrast, when the surface cyclone is initialized on the jet axis, the surface cyclone is more representative of the Norwegian cyclone model and the bent‐back warm front is almost non‐existent.

Further distribution of this work must maintain attribution to the author(s) and the published article's title, journal citation, and DOI. A search for the rare decay of a B0 or Bs0 meson into the final state J/ψγ is performed, using data collected by the LHCb experiment in pp collisions at s=7 and 8 TeV, corresponding to an integrated luminosity of 3 fb-1. The observed number of signal candidates is consistent with a background-only hypothesis. Branching fraction values larger than 1.5×10-6 for the B0→J/ψγ decay mode are excluded at 90% confidence level. For the Bs0→J/ψγ decay mode, branching fraction values larger than 7.3×10-6 are excluded at 90% confidence level; this is the first branching fraction limit for this decay.
Marital Conflict, Family Socioeconomic Status, and Depressive Symptoms in Migrant Children: A Moderating Mediational Model

The present study examines the roles of parent–child communication and peer attachment in the relationships between marital conflict, family socioeconomic status (SES), and depressive symptoms in migrant children. The present study was a cross-sectional design. A total of 437 children were selected from 2 public schools of migrant children, and they were assessed on measures of marital conflict, family SES, parent–child communication, peer attachment, and depressive symptoms. Results showed that peer attachment moderates the relationships between marital conflict, parent–child communication, and depressive symptoms. That is, for migrant children with high peer attachment, marital conflict influences depressive symptoms directly, but also indirectly through parent–child communication. For migrant children with low peer attachment, marital conflict only exerts a direct influence on depressive symptoms. In addition, parent–child communication mediates the relationship between family SES and depressive symptoms, although the mediating effects were not significant for groups with a high or a low level of peer attachment. Thus, parent–child communication serves as one critical pathway, linking marital conflict, or family SES, with depressive symptoms. Furthermore, peer attachment acts as a buffer against the negative effects of marital conflict on depressive symptoms.
Environmental determinants of infectious and chronic disease prevention behaviours: A systematic review and thematic synthesis of qualitative research

Regulatory health policies facilitate desired health behaviours in communities, and among them, smoke-free policies and COVID-19 restrictions have been widely implemented. Qualitative research studies have explored how these measures and other environmental influences shape preventive behaviours. The objective of this systematic review was to synthesize previously published qualitative research, generate across-study themes, and propose recommendations for behaviour change interventions. We used a comprehensive search strategy, relevance screening and confirmation, data extraction, quality assessment, thematic synthesis, and quality-of-evidence assessment. In total, 87 relevant studies were identified. Findings were grouped under six overarching themes and mapped under three categories: (i) the political environment, (ii) the sociocultural environment, and (iii) the physical environment. These findings provide insights into the environmental influences of behaviour and indicate future interventions may be more effective by considering moral norms, community norms, policy support, and group identity.
Observation of Helium in Mercury's Exosphere by PHEBUS on Bepi‐Colombo

On 1 October 2021, Bepi‐Colombo performed its first flyby of Mercury. During the maneuver, the short wavelength channel (55–155 nm) of “Probing the Hermean Exosphere by UV Spectroscopy” (PHEBUS) was activated for a total duration of 1 hr. The helium resonance line at 58.4 nm was clearly observed during the whole sequence. At large distance from the planet, the emission was due to helium atoms in the interplanetary medium (interplanetary UV glow). Just after crossing the terminator of the planet and entering the dawn side of the exosphere, PHEBUS observed a clear additional emission due to scattering of solar photons by helium atoms in the exosphere of Mercury. The first detection of the 58.4 nm line in the exosphere of Mercury was reported by Broadfoot et al. (1976, https://doi.org/10.1029/gl003i010p00577) following the Mariner 10 flybys in 1974. The PHEBUS observation of exospheric helium emissions is the first for this element since the UVS measurements. In this paper, we present the results of our analysis of the PHEBUS data at 58.4 nm. Calibration of both instruments are compared with observations of the interplanetary glow, showing that the measurements of both instruments are accurate. However, we find that the exospheric density of helium atoms deduced from the PHEBUS data is 4.5–7.5 times lower than the previous estimate from UVS on Mariner 10. Possible explanations are considered. We show that some of the helium atoms present in the exosphere of Mercury could originate from the local interstellar cloud.
The synthesis of gmelinite microspheres and their post-synthetic modification for improved defluoridation

ABSTRACT A method for synthesizing microspheres of the zeolite gmelinite (GME) with mean diameter 8 µm, and narrow dispersion, has been developed and establishes the key role of aging the gel prior to heating to produce a narrow size distribution. Fluoride adsorption from acidic media has been evaluated for GME microspheres following post-synthetic modifications by calcium ion exchange, iron(III) surface modification, and dealumination. In each instance, the post-synthetic modification leads to appreciable equilibrium fluoride loadings, with the highest loadings observed for dealuminated GME microspheres, capable of 97.4% fluoride removal from acidified 22 ppm fluoride solutions at equilibrium. Accordingly, dealuminated GME microspheres show promise as a potential adsorbent for reducing the aqueous fluoride content in dangerously high natural sources (up to 30 ppm) to safe drinking levels (≤1.5 ppm) in one treatment.
