Abstract

Background
The Society of Thoracic Surgeons and European System for Cardiac Operative Risk Evaluation (EuroSCORE) II risk scores are the most commonly used risk prediction models for in-hospital mortality after adult cardiac surgery. However, they are prone to miscalibration over time and poor generalization across data sets; thus, their use remains controversial. Despite increased interest, a gap in understanding the effect of data set drift on the performance of machine learning (ML) over time remains a barrier to its wider use in clinical practice. Data set drift occurs when an ML system underperforms because of a mismatch between the data it was developed from and the data on which it is deployed.

Objective
In this study, we analyzed the extent of performance drift using models built on a large UK cardiac surgery database. The objectives were to (1) rank and assess the extent of performance drift in cardiac surgery risk ML models over time and (2) investigate any potential influence of data set drift and variable importance drift on performance drift.

Methods
We conducted a retrospective analysis of prospectively, routinely gathered data on adult patients undergoing cardiac surgery in the United Kingdom between 2012 and 2019. We temporally split the data 70:30 into a training and validation set and a holdout set. Five novel ML mortality prediction models were developed and assessed, along with EuroSCORE II, for relationships between and within variable importance drift, performance drift, and actual data set drift. Performance was assessed using a consensus metric.

Results
A total of 227,087 adults underwent cardiac surgery during the study period, with a mortality rate of 2.76% (n=6258). There was strong evidence of a decrease in overall performance across all models (P<.0001). Extreme gradient boosting (clinical effectiveness metric [CEM] 0.728, 95% CI 0.728-0.729) and random forest (CEM 0.727, 95% CI 0.727-0.728) were the overall best-performing models, both temporally and nontemporally. EuroSCORE II performed the worst across all comparisons. Sharp changes in variable importance and data set drift from October to December 2017, from June to July 2018, and from December 2018 to February 2019 mirrored the effects of performance decrease across models.

Conclusions
All models show a decrease in at least 3 of the 5 individual metrics. CEM and variable importance drift detection demonstrate the limitation of logistic regression methods used for cardiac surgery risk prediction and the effects of data set drift. Future work will be required to determine the interplay between ML models and whether ensemble models could improve on their respective performance advantages.

Background
The transition from pediatric to adult care poses a significant health system–level challenge impeding the delivery of quality health services for youth with chronic health conditions. In Canada and globally, the transition to adult care is regarded as a top priority in adolescent health in need of readily applicable, adaptable, and relevant national metrics to evaluate and benchmark transition success across disease populations and clinical care settings. Unfortunately, existing literature fails to account for the lack of engagement from youth and caregivers in developing indicators, and its applicability across chronic conditions, primary care involvement, and health equity considerations.

Objective
Our proposed study aims to establish a consensus-driven set of quality indicators for the transition to adult care that are universally applicable across physical, developmental, and mental health conditions, clinical care settings, and health jurisdictions.

Methods
Using an integrated knowledge translation (iKT) approach, a panel comprising youth, caregivers, interdisciplinary health care providers, and health system leaders will be established to collaborate with our research team to ensure that the study methodology, materials, and knowledge dissemination are suitable and reflect the perspectives of youth and their families. We will then conduct an iterative 3-round Online Modified Delphi (OMD) study (n=160) to (1) compare and contrast the perspectives of youth, caregivers, health care providers, and health system leaders on quality indicators for transition; and (2) prioritize a key set of quality indicators for transition applicable across disease populations that are the most important, useful, and feasible in the Canadian context. Using the RAND/UCLA Appropriateness Method (RAM) multistage analytic approach, data from each panel and stakeholder group will be examined separately and compared to establish a key set of indicators endorsed by both panels.

Results
The study is funded by the Canadian Institutes of Health Research and Physicians Services Incorporated.

Conclusions
This study will produce quality indicators to evaluate and inform action equitably to improve transition from pediatric to adult care for youth and their families in Canada.

Contextualization: The aquatic-terrestrial transition zone (ZTAT) in the floodplain (alluvial plain) Ramsar Ayapel (Colombia) remains flooded for more than half of the year, and its coastal strip generates a strong influence on the ecosystem. An approach to the spatial and temporal characterization of this zone is crucial for further functional analysis, especially when tropical floodplains are little explored except for some Amazonian ecosystems.
Knowledge gap: Floodplain dynamics are mainly regulated by flood pulses, directly influencing he physical and chemical conditions of water and sediment. Therefore, the biota is adapted to the flooding and waterlogging conditions of the ecosystem. However, research has addressed the terrestrial and aquatic phases as separate systems, making it necessary to resort to methodologies that demonstrate connectivity in the system and facilitate the interpretation of key factors in the ecological functioning of tropical wetlands.
Purpose: The research analyzed the structure and functioning of the ZTAT through physical and chemical variables at different times of the flood pulse.
Methodology: In two wetlands of the muddy complex, sensitive to the flood pulse, three samplings were carried out: rising water (July/2021), high water (September/2021), and declining water (March/2022). The ZTAT was monitored by delimiting it into four subzones: water, sediments, floodable soil, and soil.
Results and conclusions: Significant changes in time associated with water level and nitrogen concentrations were revealed; while in space, assisted by the contrast of the ZTAT at the two sites, differences were reflected through in situ variables and soil characteristics. It was detected that depth, transparency, and a higher concentration of nitrogen forms, and some ions such as aluminum and magnesium generated differences on a time level. On the contrary, conductivity, calcium concentration, and variables associated with soil characteristics expressed it at the spatial level due to exploring the ZTAT. Therefore, the physicochemical dynamics of moments and sites in a wetland require a sampling design that, using the ZTAT, facilitates the scale of physicochemical analysis.

Published: June 2024

Abstract
The work presented is the result of the implementation of diffraction measurements: phase composition and stresses resulting from additive manufacturing process of nickel superalloy Inconel 718 components print. With the help of diffraction methodologies, the key parameters from the point of view of the quality of prints and their strength were determined. The existence of individual phases in the material after printing was demonstrated, and the surface variation of the stress values was presented, showing its dependence on the geometry of the printed part – measurements were made at various points on the surface of samples with different geometries. In addition, the variation of the stress level was shown depending on the distance of the measurement point from the build platform on which the additive manufacturing process was carried out. Components were printed on the surface of a single build plate in order to study the effect of printing differently oriented samples with respect to the platform geometry, as well as the mutual effect of the temperature of samples printed first on the stress state of elements printed in subsequent steps of the procedure, and the effect of the temperature of elements printed later on the rate of temperature decrease, and consequently on the stress state, of elements printed first.

Abstract

Aim. Hospital health care of a patient represents a part of the patient’s “journey” through the healthcare system and as such is not delivered independently, but in a personalized integrated manner. To achieve a better outcome of personalized medical health care of patients in hospital, it is necessary to systematically transform the existing clinical pathways (CPs) into integrated clinical pathways (ICPs). The aim of the study was to investigate stakeholder’s perceptions of the content and barriers to transforming CPs into ICPs on the example of a general hospital in Slovenia. That is how we obtained microdata for systemic measures at the level of general hospitals in Slovenia.

Material and methods. The cross-sectional study used a qualitative method with interviews and focus groups with patients, nurses, other healthcare workers and managers working in ICPs for chronic kidney disease and hip replacement in a typical Slovenian hospital.

Results. The results showed that ICPs could be divided into five basic phases. In all phases, additions to the existing CPs in order to turn them into ICPs were necessary, which was an additional burden, especially for the nurses.

Conclusions. Personalized health care through ICPs is patient-centered, shorter, holistic, coordinated, continuous, of higher quality for patients and sustainably more efficient for providers.

Published: June 2024

Background: Stem cells (SCs) are a type of cell that lacks specialization but possesses the unique capability to differentiate into a wide range of specialized cell forms within the body. Also, some stem cells are already partially differentiated and capable of transforming into specific types of nerve cells, for example.

Objectives: This study seeks to study the impact of stem cell usage on human rights

Theoretical framework: This study requires an examination of the concept of stem cells, their sources, the benefits of their usage, the problems that arise for humans after their usage, and the compatibility of stem cell usage with Islamic law, and national legislation, as well as international treaties and agreements

Method: The descriptive approach was adopted, relying on various sources and information to address the study's theoretical framework.

Results and conclusion: The potential for utilizing stem cells to replace or repair tissues or cells that have been harmed or destroyed by conditions including diabetes, Parkinson's disease, and spinal injuries. as well as, the possibility of stimulating SCs to specialize and transform into the cells required to replace damaged tissue, by stimulating specific genes.

Implications of the research: stem cells and their unique properties will be beneficial in several scientific and health contexts. Researchers and medical professionals think that researching stem cells will help them understand how some diseases are caused, which is one of the hopes that is built around the prospect of using SCs in the treatment of many diseases.

Originality/value: Researchers believe stem cells hold the key to replacing or repairing damaged or destroyed tissues or cells resulting from conditions such as diabetes, Parkinson's disease, and spinal cord injuries.

Published: June 2024

Purpose: This research investigates the effect of personal traits, entrepreneurial intention, and business model innovation on the success of creative sectors in Indonesia, aiming to generalize findings across the entire creative industry rather than focusing on specific sub-sectors.

Theoretical reference: The study is grounded in entrepreneurial theory and business model innovation literature, examining how individual traits and business practices influence industry performance.
Method: Data were collected through a questionnaire issued to 414 respondents within the creative sectors in Indonesia. The hypotheses were tested using structural equation modeling partial least squares (SEM-PLS).

Results and Conclusion: The results indicated that entrepreneurial intention, proactivity, and creativity significantly impact the performance of Indonesian creative industries. However, business model innovation did not have a significant effect on industry success. The study concludes that personal traits and entrepreneurial intention are critical for performance, while business model innovations may play a lesser role.

Implications of research: The research provides insights into the factors driving success in the Indonesian creative sectors, highlighting the importance of fostering entrepreneurial traits. It suggests that policy makers and industry leaders should focus on developing these traits to enhance performance.

Originality/value: This study contributes to the literature by offering a generalized analysis of the entire creative sector in Indonesia, rather than isolated sub-sectors. It underscores the sig-nificance of entrepreneurial traits in industry performance and provides a comprehensive un-derstanding of the creative industries' dynamics in a developing country context.

Published: June 2024

Introduction: This study investigates the factors influencing Thai consumers’ acceptance of plant-based food products. Drawing upon the Theory of Planned Behavior (TPB) attitudes, subjective norms, perceived behavioral control, Diffusion of Innovation Theory (DOI), personal innovativeness and environment concern, are examined as predictors of adoption intention and actual behavior.

Methods: The quantitative approaches collected data with convenience sampling method from Thai consumers using online questionnaires. A structural equation modelling (SEM) was employed to analyse the confirmatory factor analysis and path analysis on relationships among variables and hypothesis testing.

Results: The findings reveal significant positive relationships between attitudes, subjective norms, environmental concern, and personal innovativeness to adoption intention through actual behavior of plant-based food products. Perceived behavioral control did not impact adoption intention.

Discussion: The results underscore the importance of attitudes, environmental concern, subjective norms and personal innovativeness in shaping consumer behaviour towards plant-based foods. Plant-based entrepreneurs can promote adoption to behavior on product launching using various factors across research fields as marketing strategies and communication tools regarding increase the product adoption and revenue growth.

Goal: This study aimed to conduct a thorough review of the scientific literature, meticulously identifying the diverse approaches, attributes, and logical schemes used to understand the intricate dynamics of organizational culture. Theoretical framework: The principles of meta-analysis were used for the bibliographic survey to contemplate all theories and theoretical fields contained in studies on organizational culture so that a faithful representation of its conceptual scope could be obtained. Method: The conceptual bibliographic method was used in its four stages: formulation of the problem, data collection in international scientific databases, analysis and organization of the data, and consequent generation of answers to the investigation's guiding questions. Results and discussion: The results indicated the existence of 27 distinct approaches, which can be organized into seven semantic groups. One hundred-two attributes were also found, which generated ten semantic groups. The logic found is that organizational culture manifests itself through sharing its members' mental content and configuring physical and extraphysical spaces. Implications of the research: These findings shed new light on organizational culture by characterizing it as an extraphysical phenomenon that manifests itself physically, confirming new theoretical fields about organizations, such as spiritual and interpsychic dimensions. Originality/Value: This study contributes to the understanding of organizational culture by showing that rites, myths, beliefs, values, and others are merely distinct forms of manifestation of a phenomenon that is intrinsically and extrinsically non-material.

العلامات الإعرابية تنحصر في تسع علامات فقط ، هي: { الضمة ، والفتحة ، والكسرة ، والسكون ، والألف ، والياء ، والواو ، والنون ، والحذف ، وقد استعملت العربية خمس علامات منها تشترك في الدلالة على وجهين إعرابيين في حالات معينة هي { الفتحة والكسرة والألف والياء وحذف النون }، فميزتْ لنا أربع عشرة حالة إعرابية كلها لا تخرج عن حالات الرفع والنصب والجر والجزم ، فالضمة للرفع ، والفتحة للنصب وجرّ الاسم الممنوع من الصرف ، والكسرة للجرّ }، وهو ونصب جمع المؤنث السالم، والألف لنصب الاسماء الستة ورفع المثنى، والياء لـنصب المثنى وجمع المذكر السالم وجرّهما ، وحذف النون لنصب الأفعال الخمسة وجزمها .
إِنَّ هذه المصطلحات { الفتحة ، والضمة ، والكسرة } قد أخذتْ أسماءها من أوضاع الفم وما يشتمل عليه من أعضاء أخرى تحدد مخارج الأصوات عند النطق بها وبما يلتحق بها من الحركات ، فوسم الأول ضمّاً لأنّه ينشأ من ضمّ الشفتين، ووسُم الثاني كسراً ؛ لأنّه ينشأ من انجرار اللّحي الأسفل إلى الأسفل انجراراً قوياً ، وسُمّي الثالث فتحاً لأنّه يتولد من مجرد فتح الفم ، ثُـمَّ صارت هذه المصطلحات رمزاً لمقامات الإعراب والبناء، ثُـمَّ توضحتْ هذه المصطلحات وزاد تحديدها فيما بعد نتيجةً حتميةً لتوسع الدرس الصوتي واتساع مباحثه، أمّا مصطلح السكون فمأخوذ من سكون آلة النطق ؛ لأنّه ضد الحركة ، والحركة إنّما سمّيت حركةً لأنّها تحرك الحرف وتجتذبه إلى الحرف الذي هو من جنسها ،
ولا بد من الإشارة إلى أنَّ الحركات ( العلامات ) التي على أَواخر الكلم { الفتحة والضمة والكسرة } هي صور وأجزاء من أَحرف العلة ، وتفعل فعل تلك الأحرف في توجيه الموقع الإعرابي للمفردة([i]) ، وأَنَّ { السكون } هو : هو اختفاء الحركة على الحرف الساكن.
ذرائعية ثيمة الرحيل في فراقية ابن زريق البغدادي من التشكيل إلى التصوير
Authors: الحارثي نايف بن عبد العزيز 
Published: June 2024

تعد النظريات النقدية الحديثة طوق نجاة للنصوص الأدبية وفهمها، فالذرائعية مذهب فلسفي أدبي يعتمد على الحقيقة بعد التجربة الإنسانية، وابن زريق البغدادي الشاعر المشهور والمغمور في آن، أنتج لنا نصاً حياً، تتعاضد فيه الفكرة مع الأسلوب والصور الشعرية؛ لتكون لنا جسداً حياً ناطقاُ يشف لنا عن معاناة الغربة وأحوالها وأهوالها، وهو الذي سأعمل على استنطاقه من النص اليتيم، بعيداً عن الدراسات التقليدية التي تحاول تحليل العمل الأدبي وفق الأدوات الكلاسيكية، ولذا سيتناول هذا البحث فكرة الرحيل والغربة من منظور لساني بحثاً عن التشكيل، والتصوير، والقيم الجمالية، وكيفية توظيف الصور المبنيّة على المجاز توظيفاً فنياً مكثفاً؛ للكشف عن العمق الوجداني، والبعد الروحي للشاعر، في إطار شعري واحد يتمثل في الصورة المنتمية إلى عالمه النفسي.
المضمون والمبنىى في نصائح ابن ليون التجيبي الاندلسي (681ه - 750ه)
Authors: الغرباوي إسراء عبدالرضا 
Published: June 2024

الفقيه العالم الشاعر ابو عثمان سعد بن ابي جعفر احمد بن ابراهيم بن ليون التجيبي، من كبار فقهاء الاندلس، الذي اتصف بالزهد والعلم والنصح ، وسخر شعره لنشر الفضيلة و القيم الاخلاقية بين افراد المجتمع، باعتبارها سلوك انساني كونها تمثل نظام الاسلام بصورة عامة فضلا عن روحه وجوهره في جميع جوانبه.
انطلق التجيبي بناء على خلفيته الاسلامية لتوجيه ابناء جلدته الى المثل الاخلاقية العليا بعد سنوات طوال قضاها في خدمة القيم والاخلاق وابرازها والتي اكسبته خبرة في التعامل مع الناس باختلاف مشاربهم وتنوع صفاتهم فكان الشاعر الناصح ، الداعي الى التحلي بالقيم الاخلاقية والانتصار لها ، والحاث على السلوك القويم ، فجاء شعر النصح لديه هادفا الى توجيه الاخرين _ في عصره وما بعده _ نحو الاخلاق الفضلى والصفات العلى ؛ كي يستقيم سلوكهم وتحسن معاملتهم ، حسب رؤيته ومنطلقاته الثقافية والدينية والاجتماعية ، فضلا عن تجربته الشخصية .
استنادا لهذه المثل العليا التي جاء بها الدين ، تحمل ابن ليون اعباء قضايا عصره ومسؤولية تبعاتها ، من خلال تجاربه وخلاصة ثقافته ، حاملا لواء النصح والارشاد لتهذيب النفوس ؛ وتوجيهها نحو الاصلاح والالتزام بالقيم الاخلاقية النبيلة واجتناب الرذيلة
