Published: September 2024

Abstract

To assess the present and future conditions of potential deep geological repository sites, understanding their evolution in the past is mandatory. Here, glaciation cycles strongly affected the long-term thermo-hydro-mechanical (THM) evolution of the geosystem.The AREHS project studies the effects of changing boundary conditions (BCs) on the long-term evolution of large-scale hydrogeological systems. The focus is on numerical modeling using the open-source multi-field finite element code OpenGeoSys with THM couplings. The impact of the glacial THM loading is taken into account using complex time-dependent THM BCs. A generic geological model for a clay host rock formation including predominantly sedimentary rock layers is applied. Assuming the plastic flow behavior of the sedimentary rocks to share qualitative features, an elasto-plastic model is applied that can describe qualitatively a range of relevant effects (dilatancy, contractancy, consolidation etc.) with few material parameters. Special emphasis is put on the specification of a suitable initial state: To this end, an initial simulation is carried out, where a reasonable plastic pre-consolidation is adjusted. Then, the thermodynamic state is transferred in full to the subsequent simulation of two glacial cycles. As a main result, the glacial cycles lead to persistent deviations in the subsurface, e. g. long-term pressure anomalies due to THM coupling. However, under the chosen assumptions, only the first glacial cycle leads to pronounced (contractant) plastic flow whereas the second cycle merely shows elastic rock behavior.

Abstract

Conservation and assessment of germplasm resources play a crucial role in forest genetics and breeding. Eucalyptus cloeziana F. Muell is esteemed as a valuable timber tree species in China owing to its substantial economic and ecological significance. Nevertheless, there has been a dearth of research on functional genomics and molecular breeding within this species. In this study, 20 fluorescent-labeled polymorphic EST-SSR markers were utilized to genotype 448 E. cloeziana individuals from 118 families originating from 19 provenances within the State-owned Dongmen Forest Farm of Guangxi province, one of the largest gene pools of Eucalyptus in Asia. The results unveiled a relatively high genetic diversity of E. cloeziana germplasm (I = 2.310; He = 0.855) and low genetic differentiation among provenances, with the majority of genetic variation occurring within provenances (96.73%). Bayesian structure analysis grouped the tested accessions into three clusters: northern provenances, northern high-altitude provenances, and southern provenances. A core collection comprising 85 individuals (18.97% of the total breeding population of 448 individuals) was established through random non-repetitive sampling to diminish redundancy while uploading a high level of genetic diversity (I = 2.470; He = 0.890). Three loci associated with environment (EC-e039, EC-e015, and EC-e089) were identified using latent factor mixed model (LFMM) and redundancy analysis (RDA). Two temperature variables (maximum temperature of the warmest month and mean temperature of the driest quarter) and two precipitation variables (annual precipitation and precipitation of the driest month) were identified as significant environmental factors influencing adaptive variation in the species. These findings highlight the close relationship between climate conditions and genetic variability, providing valuable insights for the management of forest species in the face of a swiftly changing environment.

Published: September 2024

Abstract

Background Epidemic prevention measures in universities are very important as a special area with crowds. Many universities have taken measures of lockdown to stem the spread of COVID-19 epidemic on campus. Negatively life events such as lockdown and pandemic are important variables of depression which may affect students' mental health.
Methods AMOS24.0 analysis software packages were used for construct model to analyze the effects of exercise on depression of university student. An ANOVA analysis of variance for repeated measures was applied to analyze the differences between exercise and depression.
Results This study found that effects of exercise on university students' depression has both direct effects and mediating effects, with direct effects accounting for 43.7% and mediating effects accounting for 56.3%.The mediating effects of exercise on depression mainly included three aspects: subjective exercise experience, relative deprivation, subjective exercise experience and relative deprivation.
Conclusions Exercise intensity and exercise frequency had better effects on reduce depression. Not only did positive happiness reduce depression, but also reduce depression by controlled relative deprivation. However, exercise fatigue cause high level of depression by increased relative deprivation indirectly. Therefore, if we want to reduce depression with the help of exercise effectively, it is necessary to arrange moderate intensity exercise three times a week and pay attention to recovery after fatigue.

Abstract

The International Forum of Sovereign Wealth Funds (SWF) adopted the Santiago Principles to foster good governance, accountability, and transparency practices. The origins, objectives, market impacts, financial performance, and investment strategies of SWFs have dominated scholarly discourse. A still unsolved question is how and to what extent SWFs implement governance practices. We analyse the governance self-assessment reports of the three SWFs that are signatories to the Santiago Principles and belong to the Association of Southeast Asian Nations (ASEAN). That is, Indonesia, Malaysia, and Singapore. As SWFs grow in size and number, deepened coordination with domestic fiscal and monetary authorities will be needed. We also find that the Santiago Principles’ economic and financial targeting objective appears indifferent to the environmental and social impacts that have the potential to affect the stability of financial markets. The variation in levels of disclosure across SWFs threatens to dilute the essence of the Santiago Principles badge. Fifteen years after their formulation, the Santiago Principles show signs of needing an update to reflect emerging realities and expanded member contexts.
Comparative study of evapotranspiration from the SWAT model and MODIS-derived remote-sensing data in two climatic zones in Egypt

Published: September 2024

ABSTRACT
Evapotranspiration (ET) estimation is highly dependent on several input factors that differ between different estimation methods either from models or remote-sensing data. Therefore, the main objectives of this study are to assess and compare the ET simulated from the SWAT model and derived from MODIS (SSEBop and MOD16A2) in South-Delta (northern Egypt) and KomOmbo (southern Egypt) zones during the period from April 2013 to December 2020. The daily rainfall, maximum temperature (Tmax), minimum temperature (Tmin), solar radiation (Rs), relative humidity (RH), and wind speed (WND) from the NASA-POWER agroclimatology dataset were used to run the SWAT model. The results showed that the simulated monthly, seasonal, and annual ET from SWAT is lower than SSEBop by about −41% in South-Delta and −66% in KomOmbo and higher than MOD16A2 by about 34% in South-Delta and 28% in KomOmbo. The SWAT model may have the potential to produce reasonable ET values, as it is reliant on both climatic and actual land-surface conditions. The monthly and seasonal ET from SWAT and MODIS is positively correlated with Rs, Tmax, Tmin, and WND, and is negatively correlated with RH and rainfall, while the annual ET has varied (positive/negative) weak correlation with the weather variables.
Lyme Disease Under-Ascertainment During the COVID-19 Pandemic in the United States: Retrospective Study
Authors: Jones Brie S , DeWitt Michael E , Wenner Jennifer J , Sanders John W 
Published: September 2024

Abstract

Background
The COVID-19 pandemic resulted in a massive disruption in access to care and thus passive, hospital- and clinic-based surveillance programs. In 2020, the reported cases of Lyme disease were the lowest both across the United States and North Carolina in recent years. During this period, human contact patterns began to shift with higher rates of greenspace utilization and outdoor activities, putting more people into contact with potential vectors and associated vector-borne diseases. Lyme disease reporting relies on passive surveillance systems, which were likely disrupted by changes in health care–seeking behavior during the pandemic.

Objective
This study aimed to quantify the likely under-ascertainment of cases of Lyme disease during the COVID-19 pandemic in the United States and North Carolina.

Methods
We fitted publicly available, reported Lyme disease cases for both the United States and North Carolina prior to the year 2020 to predict the number of anticipated Lyme disease cases in the absence of the pandemic using a Bayesian modeling approach. We then compared the ratio of reported cases divided by the predicted cases to quantify the number of likely under-ascertained cases. We then fitted geospatial models to further quantify the spatial distribution of the likely under-ascertained cases and characterize spatial dynamics at local scales.

Results
Reported cases of Lyme Disease were lower in 2020 in both the United States and North Carolina than prior years. Our findings suggest that roughly 14,200 cases may have gone undetected given historical trends prior to the pandemic. Furthermore, we estimate that only 40% to 80% of Lyme diseases cases were detected in North Carolina between August 2020 and February 2021, the peak months of the COVID-19 pandemic in both the United States and North Carolina, with prior ascertainment rates returning to normal levels after this period. Our models suggest both strong temporal effects with higher numbers of cases reported in the summer months as well as strong geographic effects.

Conclusions
Ascertainment rates of Lyme disease were highly variable during the pandemic period both at national and subnational scales. Our findings suggest that there may have been a substantial number of unreported Lyme disease cases despite an apparent increase in greenspace utilization. The use of counterfactual modeling using spatial and historical trends can provide insight into the likely numbers of missed cases. Variable ascertainment of cases has implications for passive surveillance programs, especially in the trending of disease morbidity and outbreak detection, suggesting that other methods may be appropriate for outbreak detection during disturbances to these passive surveillance systems.

This study aims to investigate the mechanical properties of lightweight concrete using lightweight aggregate and analyze the impact of silica fume on enhancing its compressive strength. The main objective of this study was to improve the value of industrial waste by utilizing GGBFS as a substitute for cement. Four alternative compositions have been used to produce samples of lightweight concrete. The coarse aggregate is substituted with 100% lightweight expanded clay aggregate, whereas the fine aggregates are replaced with 100% vermiculite and 100% polystyrene bead waste. A combination of 20% GGBFS and 10% silica fume is employed for cement replacement. The materials used throughout this study consist of aluminum powder and superplasticizer. The workability, compressive strength, tensile strength, and specific gravity of concrete will be determined by testing. The waster curing will be carried out on cylindrical concrete specimens 200 mm in height and 100 mm in diameter. Experimental results showed that the concrete mixture consisting of 80% cement and 20% GGBFS as binders, along with lightweight expanded clay aggregate as coarse aggregate and vermiculite as the fine aggregate, exhibits the highest compressive strength compared to other lightweight concrete mixtures.

دور تدفقات رأس المال في معالجة معضلة الادخار/الاستثمار في دول OECD
Authors: ذنون مروان عبدالمالك , يونس سامي جميل 
Published: September 2024

تتفق معظم الدراسات الاقتصادية الحديثة على أن الادخار المحلي والاجنبي أساس النمو والتطور الاقتصادي في أي دولة متقدمة ام ناميه. كما أن تحقيق الاهداف الاقتصادية للبلد يتطلب توفير موارد مالية كافية لتمويل متطلبات الاستثمار المنتج ورفع مساهمته في الانتاج، ولبلوغ هذا الهدف ينبغي إرساء سياسات اقتصادية محكمة لاستغلال كل الوسائل التي من شأنها مضاعفة المدخرات المحلية والاجنبية.
لقد شغل لغز FH (Feldstein & Horioka, 1980: 314-329) حول دور رأس المال الأجنبي في معالجة فجوة الادخار-الاستثمار حيزاً واسعاً من الجدل والنقاش بين العديد من المفكرين الاقتصاديين ولكل منهم آراؤه الخاصة حول من يقود عملية التنمية، هل هي الموارد المحلية ام التدفقات الخارجية وايهما أكثر تأثيراً في الاستثمارات المحلية، مما مهد لظهور العديد من الأفكار والتطورات التطبيقية لاختبار صحة هذه المعضلة من خلال تفسير انتقال رؤوس الأموال الدولية بين الدول.
يتناول البحث مشكلة تزايد تدفقات رأس المال دوليا عبر البلدان، لما له من تأثيرات إيجابية على الاقتصاد إذ يمكّن صانعي القرار من تخصيص الموارد بشكل أكثر كفاءة وإعطاء مجال أكبر لإدارة المخاطر والاستجابة للصدمات الخارجية. من جانب اخر ظهر في الآونة الأخيرة اراء مضادة تشير إن زيادة تنقل رأس المال الاجنبي قد تزيد من احتمال حدوث انعكاسات مفاجئة في تدفقات رأس المال التي تزعزع استقرار الاقتصادات وتتسبب في أزمات مالية، على سبيل المثال لا الحصر الأزمة الآسيوية في عام 1997 والازمة التركية 2002 والأمريكية 2008.
يهدف البحث الى إعادة فحص العلاقة طويلة الأجل بين التدفقات الخارجية ودورها في معالجة معضلة FH وتقليص فجوة الادخار-الاستثمار في اثنى عشر دولة من دول منظمـة التعـاون والتنميـة الاقتصـاديـة وهـي (الدنمـارك، فنلنـدا، فرنسـا، ألمانيـا، اليونـان، إيطاليـا، هولنـدا، إسبـانيا، السويـد، سويسـرا، تركيـا، المملـكة المتحـدة) مستخـدما نمـاذج البيانـات المزدوجـة للفتـرة 1980-2018 ومسـتعينـا بطريقـة أنظمـة العـزوم المعممـة (SYSGMM) (Arellano & Bover, 1995: 29-51) وأظهرت النتائج توافقا كبيرا مع دراسة FH ،من ان رأس المال الأجنبي هو المحرك الأساسي للاقتصاد وان الفجوة محدودة جدا في عينة البحث.
تحليل وقياس أثر الاستثمار الأجنبي على فاعلية سوق العراق للأوراق المالية

Published: September 2024

شهد العراق بعد عام 2003 تغيرات على المستوى السياسي والاقتصادي حيث الحرية والانفتاح الاقتصادي على العالم، وحرية النشاط الخاص في الداخل فضلاً عن حرية حركة السلع والخدمات ورأس المال تجاه الخارج وحرية الاستثمار الأجنبي، والتي انعكست بظلالها على الواقع الاقتصادي، ممـا فرض ضرورة إحداث تغيرات جوهرية من حيث الشكل والمضمون، ومن هنا تنبع مشكلة البحث في مدى قدرة سوق العراق للأوراق المالية التكيف مع التحولات المالية التي يفرضها الاستثمار الأجنبي في ظل ضعف الهيكل الاقتصادي وموقعهُ في الاقتصاد العالمي. وينطلق البحث من فرضية مفادها. إن سوق العراق للأوراق المالية في ظل التحولات المالية يمكنه إن يسهم بشكل فاعل في توسيع قاعدة المستثمرين وتوفير السيولة لأغراض تمويل مشروعات التنمية والإسراع بمعدلات النمو الاقتصادي. وتوصلت الدراسة ان تفعيل قانون الاستثمار الأجنبي رقم 13 لسنة 2006 والذي سمح بدخول رؤوس الأموال الأجنبية الى البلد وتداول أسهم مختلف الشركات الأجنبية وتنفيذ نشاط التداول الالكتروني وتفعيل قاعدة بيانات السوق، انعكست بظلالها على ارتفاع مؤشرات السوق، وحصول بعض التطورات في عمل سوق الأوراق المالية، إلا إن دور السوق ما زال محدودا في الاقتصاد الوطني. بسبب ضعف مساهمة القطاع الخاص في السوق. إلى جانب حداثة تجربة العراق بما يتعلق بعمل أسوق الأوراق المالية وغياب الوعي الاستثماري، وانخفاض الدخل وعدم وجود سياسة ناجحة تشجع الاستثمار، فضلاً عن انخفاض معدلات النمو الاقتصادي بسبب عدم الاستقرار الاقتصادي والسياسي الذي يشهدهُ البلد.
