Journal ArticlePublication How perceived social support mitigates occupational stress and enhances psychological well-being in nurses returning to work after childbirth(Elsevier Inc., 2026-08)Background: The return to work from maternity leave is a time when the professional demands overlap with the new responsibilities of caring for children, which may result in psychological stress for nurses. Perceived social support can be a protective resource to buffer stress and promote adaptation.
Objective: To determine if perceived social support would moderate the relationship between occupational stress and psychological well-being for nurses who returned to work after childbirth.
Method: A cross-sectional descriptive study was carried out in ten health care facilities in Dakahlia Governorate, Egypt. Four validated Arabic questionnaires were completed by a convenience sample of 200 nurses who had returned to work within 12 months after giving birth: a demographic questionnaire, a Brief Nursing Stress Scale, a 18-item Swedish adaptation of Ryff's Psychological Well-Being Scale, and a Perceived Social Support Scale for postpartum nurses. Descriptive statistics, correlation tests, multiple regression, and Hayes' PROCESS macro were used for analyses.
Results: Occupational stress had significant negative correlation with perceived social support (r = −0.332, p < .01) and psychological well-being (r = −0.506, p < .01). Psychological well-being was positively related to perceived social support (r = 0.410, p < .01). Occupational stress was a significant negative predictor of well-being (β = −0.506, p < .001) for regression results. Moderation analysis confirmed that the negative relationship between stress and well-being was significantly mitigated by perceived social support (β = 2.500, p < .001), accounting for 52% of the variance in well-being.
Conclusion: The importance of perceived social support in decreasing stress and enhancing wellbeing of postpartum nurses suggests that multi-level supportive interventions are necessary.

Publication Open AccessJournal ArticleWhen minds and networks matter: how mental health and social capital shape social frailty in older adults(Frontiers Research Foundation, 2026-05-28)Background: Social frailty represents a critical dimension of aging, yet its specific associations with mental health and social capital remain underexplored, particularly in non-Western contexts. This study investigated the influence of psychological distress and social capital on social frailty among older adults in Egypt.
Methods: In a cross-sectional study conducted at a university hospital outpatient clinic, 316 adults aged ≥60 years were assessed using the Depression Anxiety Stress Scale-21 (DASS-21), the Personal Social Capital Scale-16 (PSCS-16), and the Social Frailty Scale (SFS-8). Data were analyzed using descriptive statistics, correlation analyses, and multiple linear regression.
Results: Participants demonstrated moderate to high levels of social frailty (Mean = 5.55 ± 1.44). A significant positive correlation was found between psychological distress and social frailty (β = 0.333, p < 0.001), while a significant negative correlation was observed between social capital and social frailty (r = −0.349, p < 0.001). Multiple regression analysis confirmed that both higher psychological distress (β = 0.369, p < 0.001) and lower social capital (β = −0.327, p < 0.001) were significant independent predictors of social frailty, after controlling for key sociodemographic and health-related covariates. The final model explained 13.5% of the variance in social frailty scores (F = 24.510, p < 0.001).
Conclusion: Psychological distress and low social capital are significant, independent contributors to social frailty in Egyptian older adults. These findings advocate for integrated geriatric care interventions that concurrently address mental well-being and strengthen social networks to effectively prevent and mitigate the adverse outcomes associated with social frailty.

Publication Open AccessJournal ArticleThe mediating role of partner support in the relationship between reproductive health concerns and psychological distress among cancer survivors(Nature Publishing Group, 2026-05-25)Cancer survivorship often includes reproductive health concerns (e.g., fertility potential and treatment‐related health problems) that elevate psychological distress. Partner support is a key, modifiable resource linked to better adjustment, yet its pathway of influence is not fully understood. To test whether partner support mediates and/or moderates the association between reproductive health concerns and psychological distress among female cancer survivors. A cross-sectional study was conducted with 202 married female cancer survivors (ages 20–49) attending the oncology departments of Tanta University Hospital, Egypt. Validated measures included the Reproductive Concerns after Cancer Scale, Partner Support Scale, and Kessler Psychological Distress Scale. Higher reproductive concerns related to greater distress (r = 0.517, p < 0.01). Partner support correlated negatively with reproductive concerns (r = − 0.446, p < 0.01) and distress (r = − 0.471, p < 0.01). Adding partner support improved prediction of distress (Model 2, R2 = 0.345); partner support was a significant negative predictor (B = − 0.364, p < 0.001). Mediation was supported: Reproductive Concerns after Cancer Scale → distress total effect B = 0.4212 (p < 0.001); direct effect B = 0.3124 (p < 0.001); indirect effect via partner support B = 0.1088, 95% CI [0.0617, 0.1613]. Moderation was not supported (interaction B≈0.000, p = 0.998). Conclusions: Reproductive concerns are associated with elevated psychological distress. Partner support partially mediates yet does not moderate this relationship, indicating a protective, indirect effect on distress. Implications for Practice: Integrate structured partner‐involved education and counselling into survivorship care to reduce distress linked to reproductive concerns (confirmed need). Screen routinely for reproductive concerns and perceived partner support and refer dyads to targeted psychosocial interventions. Training for nurses should prioritize communication about fertility/health concerns and techniques to engage partners effectively.

Journal ArticlePublication Bridging theory and practice: A systematic review of simulation-based education in nursing(Elsevier Ltd, 2026-05)Aim: To examine the effectiveness of Simulation-based education (SBE) compared with traditional lecture-based instruction across knowledge, clinical skills, clinical reasoning, affective outcomes and retention.
Background: SBE has been widely adopted in nursing curricula to facilitate the integration of theoretical knowledge with clinical practice. However, evidence regarding its effectiveness across different learning domains and simulation modalities remains variable and has not been comprehensively synthesized.
Design: A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines.
Methods: PubMed/MEDLINE, Embase, CINAHL and Scopus (2015–2025) were searched for interventional studies evaluating SBE as a primary teaching strategy. Twenty-six studies met the inclusion criteria. Risk of bias was assessed using RoB 2, ROBINS-I and the NIH Before–After tool.
Results: Across studies, SBE was associated with improvements in multiple learning outcomes compared with lecture-based or standard instruction, although findings varied across simulation modalities and outcome domains. Some high-fidelity, virtual and structured-debriefing approaches showed favorable effects on clinical reasoning and skill performance. Affective responses were mixed, with confidence often improving while some virtual modalities were associated with higher anxiety. Limited follow-up data suggested partial retention of knowledge and clinical reasoning over time.
Conclusion: SBE enhances multiple learning outcomes; however, heterogeneity in study designs and simulation approaches, together with methodological limitations and limited longitudinal evidence, indicate that findings should be interpreted cautiously and that further rigorous research is needed to clarify how simulation approaches support sustained competency development.

Publication Open AccessJournal ArticleThe influence of fear of hypoglycemia and frailty on self-efficacy in diabetes management among older adults with type 2 diabetes: a cross-sectional study(Frontiers Research Foundation, 2026-03-11)Introduction: Managing type 2 diabetes mellitus (T2DM) in older adults is challenging, particularly when complicated by fear of hypoglycemia and frailty, both of which can undermine self-efficacy, a key determinant of effective disease control.
Aim: To examine the influence of fear of hypoglycemia and frailty on self-efficacy in diabetes management among older adults with T2DM.
Methods: A cross-sectional study was conducted at diabetic clinics, with 300 adults aged ≥ 60 years using convenience sampling. Validated tools included the Fear of Hypoglycemia Screener, Chinese Frailty Screening Scale, and Diabetes Management Self-Efficacy Scale.
Results: Mean scores for fear of hypoglycemia, frailty, and self-efficacy were 36.13 ± 7.70, 12.93 ± 2.28, and 19.95 ± 3.33, respectively. Fear of hypoglycemia correlated positively with frailty (r = 0.277, p < 0.01) and negatively with self-efficacy (r = −0.270, p < 0.01). Frailty also showed a moderate negative correlation with self-efficacy (r = −0.454, p < 0.01). Regression analysis identified higher fear of hypoglycemia and frailty scores predicted lower self-efficacy (p < 0.05).
Conclusion: Interventions addressing fear of hypoglycemia and frailty are essential to enhance self-efficacy and improve diabetes self-management in older adults.

Conference PublicationPublication Orgasmic Gushing: where does the fluid come from and how is it produced?(Women in Research (WiR), 2005)There are three sexual fluids from women: lubrication (e.g. transudation of fluid across the mucosa of the vagina, and mucus from the greater vestibular glands); female ejaculation (from paraurethral glands); and gushing. Orthodox western medicine and physiology does not yet have a standardized description or explanation for the third, gushing. The present paper proposes that the gushing fluid is a filtrate of plasma, produced by the mechanism known as transudation. This is an additional application for the transudation mechanism, after the well accepted roles in lubrication of the vagina, and in generating serous fluids. The present model proposes that the fluid released in a gush arises from the ventral wall of the vagina due to the presence there of increased surface area of mucosa, dilated arterioles, pressurized venous and lymphatic plexuses, and compression provided by muscle contraction during orgasm.65478 - Some of the metrics are blocked by yourconsent settings
DatasetPublication Mapping Long Term Changes in Mangrove Cover and Predictions of Future Change under Different Climate Change Scenarios in the Sundarbans, Bangladesh(2018-05-22)Ground-based readings of temperature and rainfall, satellite imagery, aerial photographs, ground verification data and Digital Elevation Model (DEM) were used in this study. Ground-based meteorological information was obtained from Bangladesh Meteorological Department (BMD) for the period 1977 to 2015 and was used to determine the trends of rainfall and temperature in this thesis. Satellite images obtained from the US Geological Survey (USGS) Center for Earth Resources Observation and Science (EROS) website (www.glovis.usgs.gov) in four time periods were analysed to assess the dynamics of mangrove population at species level. Remote sensing techniques, as a solution to lack of spatial data at a relevant scale and difficulty in accessing the mangroves for field survey and also as an alternative to the traditional methods were used in monitoring of the changes in mangrove species composition, . To identify mangrove forests, a number of satellite sensors have been used, including Landsat TM/ETM/OLI, SPOT, CBERS, SIR, ASTER, and IKONOS and Quick Bird. The use of conventional medium-resolution remote sensor data (e.g., Landsat TM, ASTER, SPOT) in the identification of different mangrove species remains a challenging task. In many developing countries, the high cost of acquiring high- resolution satellite imagery excludes its routine use. The free availability of archived images enables the development of useful techniques in its use and therefor Landsat imagery were used in this study for mangrove species classification. Satellite imagery used in this study includes: Landsat Multispectral Scanner (MSS) of 57 m resolution acquired on 1st February 1977, Landsat Thematic Mapper (TM) of 28.5 m resolution acquired on 5th February 1989, Landsat Enhanced Thematic Mapper (ETM+) of 28.5 m resolution acquired on 28th February 2000 and Landsat Operational Land Imager (OLI) of 30 m resolution acquired on 4th February 2015. To study tidal channel dynamics of the study area, aerial photographs from 1974 and 2011, and a satellite image from 2017 were used. Satellite images from 1974 with good spatial resolution of the area were not available, and therefore aerial photographs of comparatively high and fine resolution were considered adequate to obtain information on tidal channel dynamics. Although high-resolution satellite imagery was available for 2011, aerial photographs were used for this study due to their effectiveness in terms of cost and also ease of comparison with the 1974 photographs. The aerial photographs were sourced from the Survey of Bangladesh (SOB). The Sentinel-2 satellite image from 2017 was downloaded from the European Space Agency (ESA) website (https://scihub.copernicus.eu/). In this research, elevation data acts as the main parameter in the determination of the sea level rise (SLR) impacts on the spatial distribution of the future mangrove species of the Bangladesh Sundarbans. High resolution elevation data is essential for this kind of research where every centimeter counts due to the low-lying characteristics of the study area. The high resolution (less than 1m vertical error) DEM data used in this study was obtained from Water Resources Planning Organization (WRPO), Bangladesh. The elevation information used to construct the DEM was originally collected by a Finnish consulting firm known as FINNMAP in 1991 for the Bangladesh government.48269 50 - Some of the metrics are blocked by yourconsent settings
Conference PublicationPublication Reinforced Behavioral Variability and Sequence Learning Across Species(Association for Behavior Analysis International (ABAI), 2012)Previous research shows that reinforcement of variable responding will facilitate sequence learning in rats (Neuringer, Deiss & Olson, 2000) but may interfere with sequence learning in humans (Maes & van der Goot, 2006). The present study aimed to replicate and extend previous research by assessing the role of behavioral variability in the learning of difficult target sequences across 3 species: humans (n = 60), hens (n = 18) and possums (n = 6). Participants were randomly allocated to one of three experimental conditions (Control, Variable, Any). In the Control conditions sequences were only reinforced if they were the target sequence, in the Variability conditions sequences were concurrently reinforced on a Variable Interval 60-s schedule if the just entered sequence met a variability criterion, and in the Any condition sequences were concurrently reinforced on a Variable Interval 60-s schedule for any sequence entered. The results support previous findings with animals and humans; hens and possums were more likely to learn the target sequence in the Variability condition, and human participants were more likely to learn the target sequence in the Control condition. Possible explanations for differences between the performance of humans and animals on this task will be discussed.39949 1 - Some of the metrics are blocked by yourconsent settings

Publication Open AccessJournal ArticleA Review into Effective Classroom Management and Strategies for Student Engagement: Teacher and Student Roles in Today’s Classrooms(Redfame Publishing Inc, 2019-12)A teacher's role encompasses far more than just imparting curricula outcomes to their students: they need to equip students with the necessary tools to experience social and academic success both inside the classroom and beyond it. Teachers need to empower students with the means to critically analyse the world around them in order to develop into critical independent thinkers. Students need to be proficient in utilising skills associated with higher levels of thinking, that will empower them with the ability to identify, analyse and evaluate the infinite volume of information available through our rapidly changing digital world. Just as teachers need to take responsibility for the various methods of teaching and instruction in the classroom, it is essential for students to take ownership of the learning process, to ensure future success in university environments, where sustained personal effort and metacognitive skills are fundamental to academic success. The object of the review of the literature surrounding the roles of teacher and student, effective classroom management strategies, and successful evidence-based teaching and learning pedagogies, is to assist new and experienced teachers in the promotion of a positive classroom experience for all.32546 52583
