A Latent Profile Analysis of Covid-19-Related Post-Traumatic Stress Disorder Symptoms in American Adults: Exploring Avoidance Symptom Variability and Insights Toward Dimensional Diagnostic Frameworks

The COVID-19 pandemic’s widespread, prolonged stressors profoundly impacted mental health, with 35.2% of participants exhibiting probable PTSD, 56.6% anxiety, and 34.1% depression. Latent profile analysis revealed five distinct PTSD symptom profiles, including Profile 2, characterized by high intrusion, moderate hyperarousal, low active avoidance, and elevated anhedonia. This unique profile underscores the need for a dimensional diagnostic approach integrating active and passive avoidance to address the heterogeneous presentations of PTSD. Sociodemographic analyses identified younger adults, females, racial/ethnic minorities, healthcare workers, urban residents, and individuals with children in the household as disproportionately affected. Moderation analyses revealed that younger adults were more susceptible to anxiety’s impact on PTSD symptoms. These findings highlight the need to refine diagnostic frameworks, expand equitable and culturally sensitive mental health care, and develop tailored interventions addressing comorbidities. Longitudinal monitoring and preventative strategies are critical for reducing disparities and enhancing future crisis preparedness.M.A

Risks Facing the Profit-loss Sharing Banking System Within The Global Financial Crisis

بينما واجهت البنوك التقليدية تحديات لمعالجة المشاكل الناشئة عن اسو ازمة مالية تعلق في الذاكرة الحية، عرف النظام البنكي الاسلامي ازدهارا نسبيا.             ومع ذلك فان التغيرات الديناميكية التي حدثت في عالم المال العالمي فرضت على المؤسسات المصرفية مخاطر مختلفة. فالبنوك الإسلامية ليست في منأى عن هذه المخاطر.  ويتعلق ازدهارها المستمر نسبيا على كيفية إدارتها لهذه المخاطر.  وان تحديد هذه المخاطر يسمح بايجاد الحلول لها. وعكس البنوك التقليدية، فان البنوك الإسلامية شترك في المخاطر مع المستثمرين والمقترضين معا.             ويكمن الاختلاف في طبيعة تقاسم المخاطر. وتبحث هذه الورقة مختلف أنواع المخاطر المرتبطة بمختلف نظم العقود المالية المختلفة التي تواجهها البنوك الإسلامية.  وتتناول الورقة أيضًا العديد من الآثار السياسية المترتبة لتعزيز إدارة المخاطر من حيث العولمة والتغيرات الثقافية داخل الصناعة المصرفية القائمة على التشارك في الربح والخسارة.While conventional banks are facing challenges to resolve problems emanating from the worst financialcrisis in living memory, the Islamic banking sector is flourishing and remains in relative prosperity.However, dynamic changes occurring in the global financial world pose various risks to bankinginstitutions. Islamic banks are not immune to such risks. Their relative continuous prosperity depends on howwell they manage such risks. Identifying these risks sheds light on challenging these risks. Unlike conventionalbanks, Islamic banks share business risks with investors and borrowers. The difference lies in the nature of risksharing. This paper examines the different types of risks associated with different schemes of financialcontracts that Islamic banks are facing. The paper also addresses several policy implications to promote riskmanagement in terms of globalization and culture changes within profit-loss sharing banking industry

The Impact of the Key Dimensions of Entrepreneurship on Opportunities for the Success of New Ventures in the Greater Amman Municipality

This research attempted to shed light on the effects of entrepreneurship dimensions on small businesses. The research aimed to study the impact of key dimensions of entrepreneurship on opportunities of venture survival and growth. The independent variables selected for this study are related to the five dimensions of entrepreneurship—characteristics of entrepreneur, entrepreneurship support policy, general environment, entrepreneurship activities, and information and electronic entrepreneurship—and their effect on survival and growth opportunities of small projects (the dependent variables). The research results and analysis revealed no significant impact on growth opportunities for small businesses. There is significant support for policy enhancing the general environment and chances for business survival and growth. There was no impact from information and electronic entrepreneurship on survival and growth chances. Finally, the authors present several recommendations including inviting Jordanian companies and governmental institutions and organizations to adopt  entrepreneurship concepts and practices, bringing more attention to entrepreneurship concepts as well as providing  technical and financial assistance to new entrepreneurs, issuing an annual  report on the entrepreneurial activities and projects, and  encouraging studies and research on the entrepreneurship in Jordan. Keywords: Entrepreneurship, leadership, entrepreneurial dimension properties, and chances of survival

Numerical Simulations of Convection with a Horizontal Magnetic Field

A numerical study of magnetoconvection with a horizontal magnetic field in a plane layer geometry is conducted. Novel dynamical regimes are observed beyond those occurring in classical (i.e non-magnetic) Rayleigh-B&eacute;nard convection. Imposed magnetic field strengths up to Chandrasekhar numbers of Q = 106 are investigated. The most unstable flow configuration is two-dimensional rolls oriented parallel to the direction of the imposed magnetic field in which the induced magnetic field is identically zero. The convective roll structure exhibits a preferential flow alignment along the direction of the imposed magnetic field thereby sustaining an anisotropic flow field. Deviations away from the convective roll structure induce a magnetic field separate from the externally-imposed magnetic field. For weak magnetic field strengths (Q = 102), we observe the Nu &sim; Ra2/7 scaling law, where Nu is the Nusselt number, though the overall heat transfer is less than that observed in non-magnetic Rayleigh-B&eacute;nard convection; we hypothesize this reduction is due to the presence of ohmic dissipation. For Q = 104 and 106 we find that the two-dimensional convective roll structure is maintained for Ra values orders of magnitude larger than the critical Rayleigh number. In this flow regime our calculations suggest a Nu &sim; Ra0.37 power law. Two-dimensional turbulence is not observed in any of the imposed magnetic field regimes, rather we observe turbulent flow behavior when the flow becomes three-dimensional. For Q = 104 we observe the development of large-scale modulations along the direction of the magnetic field when Ra &ge; 6&times;105. For Q = 104 and 6&times;105 &le;Ra &le; 107 the Nu &sim; Ra2/7 power law is observed. In general, for sufficiently strong magnetic fields, we find three primary regimes: (1) laminar, 2D convection with a heat transfer scaling that exceeds Nu &sim; Ra1/3; (2) a transitional region where 3D modulations begin and the heat transfer scaling law is reduced; and (3) anisotropic 3D convection with Nu &sim; Ra2/7 but with an overall heat transfer that is always less than the hydrodynamic case. A fourth regime at very high Rayleigh numbers, in which the convection is no longer influenced by the magnetic field, is hypothesized to occur, but not observed in the simulations.</p

Internationalization of Education and the Brain Drain Paradox: Case of the Mena Region

This paper discusses how the internationalization of higher education has brought about its impact in terms of spreading standardized academic programs, scientific research, innovation, culture exchange, and strengthening ties between involved higher education institutions and countries to resolve mutual benefit challenges. Among these challenges, the brain drain paradox remains an annoying problem for developing countries. The paper sheds light on these related issues through witnessed education system reform, research efforts exchange, and cooperation between collaborating countries in the MENA region to diminish the impact of the brain drain paradox

A Comparative study between Different Treatment Modalities of Floating Knee Jnjury At Aswan University Hospital

Purpose: The study aimed at presenting a comparison between the modalities of treatment different of floating knee injury at Aswan University Hospital.  Materials and Methods:  This study is a prospective study including all of our 20 cases of floating knee injuries who were treated utilizing various treatment modalities at Aswan University Hospital between December 2018 and September 2019 with a follow-up period of 12 months  Results: Based on the data analysis,  nailing is a better modality in floating knee injury (especially with diaphyseal long bone). Moreover, plating is a good choice for distal fractures, the external fixator is considered a choice for limb saving(as in popliteal ischemia, open fractures(OG3), and compartment syndrome).  Conclusion: Management of floating knee injury is critical as floating knee injury is not like other fractures. Floating knee injuries are serious injuries with a high rate of complications. Besides being caused by high-energy trauma with extensive skeletal and soft tissue damage, they are also associated with potentially life-threatening injuries of the head, chest, and abdomen. There are multiple controversies in surgical management starting from choosing suitable fixation for each patient according to variable conditions.  Floating knee injury remains a challenging orthopedic problem in which regaining good knee function outcome is a major concern. Stable osteosynthesis to achieve rigid fixation and early mobilization should always be attempted
