This study aims to test the mediating effect of psychological distress and bullying victimization on the relationship between alexithymia and fibromyalgia (FM) among school adolescents.

This study used cross-sectional, correlational design. Data was collected using self-administered questionnaire. The sample consisted of 1,000 school adolescents at Grade 9–12 who were recruited randomly using multistrategic sampling technique.

The analysis showed that alexithymia was a significant predictor of FM (odds ratio [OR] = 1.065). Psychological distress was also a significant predictor of FM; however, its mediating effect resulted in drop of OR to 1.041. The joined effect of bulling victimization and psychological distress found to be significant although OR dropped from 1.065 to 1.039.

The study highlights the significant role of school health nurses and mental health counselors to early detect and direct mental health interventions toward significant psychological problems among school adolescents.

This study aims to examine the predictive power of childhood adversity and severity of positive symptoms on suicidality, controlling for selected sociodemographics factors, among hospitalized patients diagnosed with schizophrenia in Jordan.

This study used a descriptive-explorative design. The study was conducted at two major psychiatric hospitals in Jordan. The targeted sample was 66 patients diagnosed with schizophrenia. Data was collected using a structured format in the period February–April 2024.

A two-step multiple hierarchical regression analysis was conducted. In the first model, childhood adversity and the severity of positive symptoms were entered. In the second model, sociodemographic variables were entered. The analysis revealed that the first model (F = 5.35, p = 0.007) was statistically significant. The second model (F = 717, p < 0.001) was statistically significant. Furthermore, the analysis revealed that childhood adversity was not a significant predictor for suicidality. However, positive symptoms and patients’ demographics (age, number of hospitalizations and length of being diagnosed with schizophrenia) were significant predictors of suicidality. The analysis revealed that childhood adversity was not a significant predictor of suicidality. However, positive symptoms and patients’ demographics (age, number of hospitalizations and length of being diagnosed with schizophrenia) were significant predictors of suicidality.

One limitation of this study is related to the sample and the setting where there were only 66 patients recruited from governmental hospitals within inpatient wards. Thus, the upcoming studies should include more participants from private hospitals and different hospital settings including outpatient and emergency departments.

The research provides empirical insights that positive symptoms, age hospitalization and schizophrenia diagnosis length were significant predictors of suicidality. At the same time, childhood adversity was not a significant predictor of suicidality.

The current research contributes to expanding mental health studies. Moreover, this study enlarges the body of knowledge in the academic world and clinical settings. It supports the disciplines of psychology, mental health and social sciences by increasing knowledge of the complicated relationships among childhood adversity, positive symptoms and suicidality.

This paper fulfills an identified need to study childhood adversity with comorbid psychiatric disorders such as schizophrenia, as well as psychiatric mental health covariates.

An audit committee (AC) whose members hold multiple directorships can adversely affect a firm’s earnings management (EM) behavior due to a lack of time that can prevent members from performing their responsibilities effectively. This paper aims to investigate the moderation role of foreign ownership (FOWN) on audit committee multiple directorships (ACMD) as it relates to accrual EM.

Using a sample of 528 observations for Palestinian listed companies over 2009–2019, this research used panel data regression to explore the specified relationships. Additionally, the study conducted a regression analysis using alternative measurements of the ACMD and the extended modified Jones model (2006) to assess robustness. Furthermore, generalized method of moments and a two-stage least squares method were used to address potential endogeneity concerns.

The results show that multiple directorships lead to a scarcity of time that can adversely affect efficient management oversight and documented an adverse association between FOWN and discretionary accruals. The results are consistent with agency theory that FOWN brings in expertise and experience from countries with strong governance to benefit local firms and thus recover control, lower agency costs, raise a firm’s value and thus alleviate EM.

This study provides unique explanations and recommendations for restraining excessive ACMD because this practice decreases managers’ ability to decrease EM. The mixed outcomes in earlier literature on the AC characteristics and EM also indicate a contingent role that may clarify this inconsistency.

This study aims to evaluate and summarize the effectiveness of cognitive behavioral therapy (CBT) and internet-based CBT (ICBT) interventions on relapse prevention and severity of symptoms among individuals with major depressive disorder (MDD). CBT is one of the most used and suggested interventions to manage MDD, whereas ICBT is a novel effective proposed approach.

The review was conducted following the preferred reporting items for systematic review and meta-analysis protocol. A comprehensive and extensive search was performed to identify and evaluate the relevant studies about the effectiveness of CBT and ICBT on relapse prevention and severity of symptoms among patients with MDD.

A total of eight research studies met the inclusion criteria and were included in this systematic review. RCT studies were conducted to assess and evaluate the effectiveness of CBT and ICBT on relapse prevention and severity of symptoms among patients with MDD. It has been found that CBT is a well-supported and evidently based effective psychotherapy for managing depressive symptoms and reducing the relapse and readmission rate among patients diagnosed with MDD. The ICBT demonstrated greater improvements in depressive symptoms during major depressive episodes among patients with MDDS. The ICBT program had good acceptability and satisfaction among participants in different countries.

Despite the significant findings from this systematic review, certain limitations should be acknowledged. First, it is important to note that all the studies included in this review were exclusively conducted in the English language, potentially limiting the generalizability of the findings to non-English speaking populations. Second, the number of research studies incorporated in this systematic review was relatively limited, which may have resulted in a narrower scope of analysis. Finally, a few studies within the selected research had small sample sizes, which could potentially impact the precision and reliability of the overall conclusions drawn from this review. The authors recommend that nurses working in psychiatric units should use CBT interventions with patients with MDD.

This paper, a review of the literature gives an overview of CBT and ICBT interventions to reduce the severity of depressive symptoms and prevent patients’ relapse and rehospitalization and shows that CBT interventions are effective on relapse prevention among patients with MDD. In addition, there is still no standardized protocol to apply the CBT intervention in the scope of reducing the severity of depressive symptoms and preventing depression relapse among patients with major depressive disorder. Further research is needed to confirm the findings of this review. Future research is also needed to find out the most effective form and contents of CBT and ICBT interventions for MDD.

CBT is a psychological intervention that has been recommended by the literature for the treatment of major depressive disorder (MDD). It is a widely recognized and accepted approach that combines cognitive and behavioral techniques to assist individuals overcome their depressive symptoms and improve their overall mental well-being. This would speculate that effectiveness associated with several aspects and combinations of different approaches in CBT interventions and the impact of different delivery models are essential for clinical practice and appropriate selection of the interventional combinations.

This systematic review focuses on the various studies that explore the effectiveness of face-to-face CBT and ICBT in reducing depressive symptoms among patients with major depressive disorder. These studies were conducted in different countries such as Iran, Australia, Pennsylvania and the USA.

Adolescence is a developmental stage of transition that is marked by multiple biopsychosocial changes that affect their well- and ill-being. This study aims to examine the multidimensional of well- and ill-being among adolescents, and to understand the relationship between well-being and depression using the PERMA model among school-age adolescents.

A descriptive, cross-sectional design was used to recruit 625 school-age adolescents (343 males and 282 females), using convenience sampling technique from the central district of Jordan. Self-administered questionnaire was used to collect data in relation to depression and well-being.

The analysis revealed that 32% had a well-being score below the median and 19% had severe depressive symptoms. Depression and well-being were moderately correlated, with the connectedness dimension being the most correlated to depression, whereas the engagement dimension was the least correlated. Females had higher scores on all subscales of depression and a significantly higher score on depression than males, whereas males had higher scores on all well-being dimensions and significantly higher scores on overall well-being than females.

Adolescents’ mental health is compromised and affected by their perception of well-being, and a comprehensive psychoeducation for adolescents on how to enhance well-being might combat development of depressive symptoms.

This study used all PERMA model components to provide an in-depth description of adolescents’ well-being, which is a crucial initial phase in better understanding how this age group experiences well-being and how it connects to their ill-being, as indicated by their depressive symptoms. The in-depth description of adolescents’ well-being will aid in planning early intervention and prevention programs for mental illness.

This paper aims to identify the most common fungal species that grow on paper manuscripts and cause bio-deterioration. It also detects the impact of additive materials on fungal degrading and builds a wide database. Thus, it helps conservators understand this phenomenon.

In total, 15 samples were collected from different paper manuscripts suffering from fungi. The achievement of the study objectives depends on using a variety of analyzes, such as a microbiological study, which indicated that three main fungi grew on the paper samples. Then, a digital microscope and an environmental scanning electron microscope were used to detect the effect of fungi on paper fibers. Fourier transform infrared microscopy was used to identify the binding medium and the X-ray diffraction method was used to measure the crystallinity index of cellulose of the paper samples.

Arabic gum was used as a binder medium with the samples. Aspergillus Niger, Aspergillus Fumigatus and Aspergillus Clavatus were the most common fungal species that grew on the Qur’an papers under investigation. They also caused much common damage to the paper samples. The results of the analyzes also showed that the highest crystallinity index of cellulose was in the samples that contained the lowest rate of fungal growth.

This paper highlights the relationship between fungal degradation and the multi-component nature of paper manuscripts. It builds a wide database that correlates the composition and the degradation of the Qur’an papers.

This systematic review (SR) aims to evaluate and summarize the effectiveness of using eye movement desensitization and reprocessing (EMDR) intervention among individuals diagnosed with post-traumatic stress disorder (PTSD), as well as to highlight the standardized EMDR-based interventional protocol.

This SR is guided according to preferred reporting items for SRs and meta-analyses standards. Several online databases were used in searching for eligible studies in peer-reviewed journals relevant to the study keywords. The included studies were SRs and clinical trials that used EMDR interventions among patients experiencing PTSD symptoms, older than 18 years and were published in English language from 2015 to 2022. Three researchers independently contributed to study selections, data extraction and study evaluations from different aspects, including quality assessment, risk of bias and study synthesis.

A total of eight published studies met the inclusion criteria and were included in this SR; four articles were randomized controlled trials and four were SR and meta-analysis studies. In all included studies, the EMDR was used as a primary psychotherapy intervention for PTSD symptoms. The results of this extensive and comprehensive review showed that EMDR is an effective psychotherapeutic intervention to reduce and control the severity of symptoms among individuals with PTSD.

It is important to acknowledge several limitations inherent in this study. First and foremost, it is noteworthy to mention that only studies conducted in the English language were included in this review, potentially restricting the overall scope and diversity of the findings. Furthermore, the number of studies incorporated into this review was limited, which may have implications for the comprehensiveness and generalizability of the results. Finally, it is worth noting that certain studies within this review had a relatively small sample size, which could potentially limit the statistical power and precision of the conclusions drawn.

This paper, a review of the literature, gives an overview of EMDR effectiveness, provides baseline information and plays a significant role in decreasing the gap in Jordanian literature regarding using EMDR as the strongest evident psychotherapy approach for PTSD treatment to help psychiatrists, psychologists and psychiatric nurses in the health-care sectors to design comprehensive strategies to enhance and improve the quality of health care and patients’ status.

EMDR intervention offers significant alternative treatment opportunities for individuals suffering from PTSD, depression and anxiety. The implementation of EMDR for depression, anxiety and PTSD improves patient outcomes as compared to standard therapeutic modalities in PTSD.

This SR gives an overview and explains strong supportive evidence for the effectiveness of EMDR interventions among individuals with PTSD. Therefore, EMDR therapy could be assumed as one standard treatment option for PTSD, aiming at reducing treatment duration and cost of treatment and restoring the mental well-being and functionality of those suffering from PTSD.

This research aims to systematically review studies on significant risks for Critical Infrastructure Projects (CIPs) from selected top-tier academic journals from 2011 to 2023.

In this research, a three-step systematic literature review methodology was employed to analyse 55 selected articles on Critical Infrastructure Risks (CIRs) from well-regarded and relevant academic journals published from 2011 to 2023.

The findings highlight a growing research focus on CIRs from 2011 to 2023. A total of 128 risks were identified and grouped into ten distinct categories: construction, cultural, environmental, financial, legal, management, market, political, safety and technical risks. In addition, literature reviews combined with questionnaire surveys were more frequently used to identify CIRs than any other method. Moreover, oil and gas projects were the subjects most often explored in the reviewed papers. Furthermore, it was observed that publications from Iran, the USA and China dominated CIRs research, making significant contributions, accounting for 49.65% of the analysed articles.

This research specifically focuses on five types of CIPs (i.e. roadways, bridges, water supply systems, dams and oil and gas projects). Other CIPs like cyber-physical systems or electric power systems, were not considered in this research.

Governments and contracting firms can benefit from the findings of this study by understanding the significant risks associated with the execution of CIPs, irrespective of the nation, industry or type of project. The results of this investigation can offer construction professionals valuable insights to formulate and implement risk response plans in the early stages of a project.

As a novel literature review related to CIRs, it lays the groundwork for future research and deepens the understanding of the multi-faceted effects of these risks, as well as sets practical response strategies.

The purpose of this paper is to address various works on mixed convection and proposes 10 unified models (Models 1–10) based on various thermal and kinematic conditions of the boundary walls, thermal conditions and/ or kinematics of objects embedded in the cavities and kinematics of external flow field through the ventilation ports. Experimental works on mixed convection have also been addressed.

This review is based on 10 unified models on mixed convection within cavities. Models 1–5 involve mixed convection based on the movement of single or double walls subjected to various temperature boundary conditions. Model 6 elucidates mixed convection due to the movement of single or double walls of cavities containing discrete heaters at the stationary wall(s). Model 7A focuses mixed convection based on the movement of wall(s) for cavities containing stationary solid obstacles (hot or cold or adiabatic) whereas Model 7B elucidates mixed convection based on the rotation of solid cylinders (hot or conductive or adiabatic) within the cavities enclosed by stationary or moving wall(s). Model 8 is based on mixed convection due to the flow of air through ventilation ports of cavities (with or without adiabatic baffles) subjected to hot and adiabatic walls. Models 9 and 10 elucidate mixed convection due to flow of air through ventilation ports of cavities involving discrete heaters and/or solid obstacles (conductive or hot) at various locations within cavities.

Mixed convection plays an important role for various processes based on convection pattern and heat transfer rate. An important dimensionless number, Richardson number (Ri) identifies various convection regimes (forced, mixed and natural convection). Generalized models also depict the role of “aiding” and “opposing” flow and combination of both on mixed convection processes. Aiding flow (interaction of buoyancy and inertial forces in the same direction) may result in the augmentation of the heat transfer rate whereas opposing flow (interaction of buoyancy and inertial forces in the opposite directions) may result in decrease of the heat transfer rate. Works involving fluid media, porous media and nanofluids (with magnetohydrodynamics) have been highlighted. Various numerical and experimental works on mixed convection have been elucidated. Flow and thermal maps associated with the heat transfer rate for a few representative cases of unified models [Models 1–10] have been elucidated involving specific dimensionless numbers.

This review paper will provide guidelines for optimal design/operation involving mixed convection processing applications.

This paper aims to explore, through a numerical study, buoyant convective phenomena in a porous cavity containing a hybrid nanofluid, taking into account the local thermal nonequilibrium (LTNE) approach. The cavity contains a solid block in the shape of a cross (+). It will be helpful to develop and optimize the thermal systems with intricate geometries under LTNE conditions for a variety of applications.

To attain the objective, the system governing partial differential equations (PDEs), expressed as functions of the current function and temperature, and are solved numerically by the finite difference approach. The authors carefully examine the heat transfer rates and dynamics of the micropolar hybrid nanofluid by presenting fluid flow contours, isotherms of the liquid and solid phases, as well as contours of streamlines, isotherms and concentration of the fluid. Key parameters analyzed include heated length (B = 0.1–0.5), porosity (ε = 0.1–0.9), heat absorption/generation (Q = 0–8), length wave (λ = 1–3) and the interphase heat transfer coefficient (H* = 0.05–10). The equations specific to the flow of a micropolar fluid are converted into classical Navier–Stokes equations by increasing the porosity and pore size.

The results showed that the shape, strength and position of the fluid circulation are dictated by the size of the inner obstacle (B) as well as the effective length of the heating wall. The lower value of obstruction size, as well as heating wall length, leads to a higher rate of heat transfer. Heat transfer is much higher for the higher amount of heat absorption instead of heat generation (Q). The higher porosity values lead to lesser fluid resistance, which leads to a superior heat transfer from the hot source to the cold walls. The surface waviness of 4 leads to superior heat transfer related to any other waviness.

This work can be further investigated by looking at thermal performance in the existence of various-shaped obstructions, curvature effects, orientations, boundary conditions and other variables. Numerical simulations or experimental studies in different multiphysical contexts can be used to achieve this.

Many technical fields, including heat exchanging unit, crystallization processes, microelectronic units, energy storage processes, mixing devices, food processing, air conditioning systems and many more, can benefit from the geometric configurations investigated in this study.

This work numerically explores the behavior of micropolar nanofluids (a mixture of copper, aluminum oxide and water) within a porous inclined enclosure with corrugated walls, containing a solid insert in the shape of a cross in the center, under the oriented magnetic field, by applying the nonlocal thermal equilibrium model. It analyzes in detail the heat transfer rates and dynamics of the micropolar nanoliquid by presenting the flow patterns, the temperature of liquid and solid phases, as well as the variations in the flow, thermal and concentration fields of the fluid.
