Creators: name: Adel, Adel Nsib
Publisher: name: European Journal of Social Impact and Circular Economy
Year: 2022

description: The main purpose of this paper is to investigate relationship between foreign direct investment and economic growth for MENA countries from 1990 to 2014. We firstly tested heterogeneity and cross sectional dependence and found that all series have homogeneity and cross sectional dependence. For that reason, Hadri Kruzomi and Pesaran et al. Multifactor Error Structure panel unit root tests were used. For obtaining long-run relationship, we used Weterlund's panel and group cointegration tests. The results supported the long-run relationship, therefore, we used Common Correlated Effect Model, thanks to this method, and coefficients for each cross-section unit could be calculated individually.

description: One of the largest items of expense in crop production is the cost of owning and operating farm machinery. Undoubtedly, machinery cost varies widely from one farm to another. Cost per acre, per hour, and per unit of production also varies widely among farms. This variation is in part a result of differences in size of farms and consequently in the volume of production over which fixed costs can be spread. Also, part of the variation is due to the success with which individual farmers adapt their use of machinery to the particular needs of their farms. The purpose of the study reported here was to estimate the cost, including labor cost, of owning and operating tractors and the 13 major farm implements used on farms in northwestern Ohio, and to show how this cost was affected by the size of farms. The report presents estimates of cost per unit of use on three sizes of farms. This is one of a group of studies by the Economic Research Service on cost of production by size of farm in several major type-of-farming areas.

description: Long non-coding RNAs (lncRNAs) play important regulatory roles in hepatocellular carcinoma (HCC). However, the function of LOC107985656 in HCC progression remains unclear. The lncRNA, mRNA and miRNA levels in HCC tissues or cells were measured using real-time quantitative polymerase chain reaction (RT-qPCR). The proliferation of cancer cells was evaluated using 3-(4, 5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) viability and colony formation assays. Bioinformatics prediction, dual luciferase assay and RNA pull-down assay were performed to analyze the relationships between LOC107985656 and miR-106b-5p, or miR-106b-5p and large tumor suppressor 1 (LATS1). The protein expression levels were detected using Western blot. Results showed that LncRNA LOC107985656 was downregulated in HCC tissues and cells. Upregulation of LOC107985656 inhibited the proliferation of HCC cells, whereas its knockdown promoted this phenomenon. LOC107985656 could activate the tumor-suppressive Hippo pathway by repressing yes association protein (YAP) and WW domain-containing transcription regulator protein 1 (WWTR1, also known as TAZ) (two homologs of Yki) protein expression in HCC. Further investigation suggested that LOC107985656 regulated the expression of LATS1 by acting as a sponge for absorbing miR-106b-5p in HCC cells. In conclusion, this study unraveled the role of LOC107985656 following a ceRNA (competing endogenous RNAs) mechanism for the miR-106b-5p/LATS1 axis in HCC. The results indicate potential diagnostic and therapeutic applications of LOC107985656 in HCC.

description: Thymoma is the most common primary mass in anterior mediastinum. Although associated with low malignancy, it is often accompanied by myasthenia gravis resulting in poor prognosis. Due to the dual factors of tumor immune tolerance and autoimmune reaction, it is urgent to understand the immune status of MG with thymoma. In this study, RNA sequencing data were obtained from the TCGA and GEO cohorts to identify differentially expressed messenger RNAs and infiltrated immune cells. A total of 121 samples in TCGA and 43 samples in GEO were screened out. The infiltrated immune cells were identified by CIBERSORT, in which Tfh cells and activated DC cells were abnormal in thymoma patients. The differently expressed genes were performed by package LIMMA. The functional characteristics of differently expression genes were analyzed by GO and KEGG; one GO and seven KEGG pathways were both found in both TCGA and GEO cohorts. Meanwhile, 27 common differently expressed genes were obtained and were displayed by a Venn diagram. The TRRUST was used to screen the hub genes for the common 27 different genes and 6 genes were found. Then, PPI networks were constructed. Subsequently, the relationship between SCNAs of common genes and related immune cells tested by TIMER. Kaplan–Meier plots, ROC curve and Cox’s expression model for immune infiltration and hub genes were also tested. In conclusion, we found that two types of immune infiltrated cells and six hub genes can predict the occurrence of myasthenia gravis in thymoma patients.

description: Urban green infrastructures have been extensively studied for their ability to mitigate the urban heat island (UHI) effect. However, allotment gardens (AGs)—a prominent type of urban green infrastructure within many European cities—have not yet been comprehensively investigated concerning their microclimates. In this study, nocturnal air temperatures (TN) in 13 AG complexes (AGCs) were measured during the summer of 2018 in Berlin, Germany. These were compared to measurements in densely built-up urban areas (URB), two large inner-city parks and rural areas (RUR). On average, the assessed AGCs were 2.7 K cooler at night than URB. Most of the investigated AGCs (11/13) displayed a larger mean TN difference to URB (∆TN AGC ) than the examined urban parks. RUR showed the largest differences to URB (∆TN RUR), indicating a UHI effect. Furthermore, the influence of land surface characteristics of the AGCs on ∆TN AGC was analyzed. ∆TN AGC decreased significantly as the floor space index around AGCs increased. The analysis of the shape complexity also produced a significant positive correlation with ∆TN AGC. In contrast, size and distance to the city center of an AGC decreased significantly with increasing ∆TN AGC. This study provides first insights into the microclimate of AGs and influencing variables concerning TN.

description: Periodic daily fluctuating demand for energy and power is a perceptible phenomenon, resulting in some moments of low demand for power and energy related to the huge energy comes from renewable energy systems, and some moments of peak load demand. This phenomenon, when combined with the non-stationary operation of huge capacity of renewable energy systems, results in no stability of voltage and frequency. To assure continuous network stability and to avoid energy losses from renewable energy systems that are subject to such control system, a hybrid system with energy–power storage in the form of pumped-hydro storage is considered the most suitable technically. This paper presents the design, modeling, analysis, and feasibility study of a hybrid wind and water-pumping storage system. The system was designed and analyzed for King Talal Dam (KTD), which is in Northern Jordan. The importance of this study is that it is directed mainly to Jordan and the Middle East and North Africa (MENA) region in general. The Jordanian renewable energy market is a promising arena that encourages developers, investors, engineers, and companies to develop and install pure renewable energy systems and renewable energy hybrid projects for the generation of electricity. The analysis of wind data is carried out using the “windfarm” software with 5.16 m/s as average wind speed. It is followed by the design of the hybrid system, which is simulated for a daily operation of 2–3 h as peak load hours. Based on the technical outcomes, cost study and feasibility analyses are carried out with Jordanian market prices. The total estimated annual energy production is 26,663,933 kWh from 10 MW wind farm and 5.2 MW pumping storage system. The aforementioned studies showed that a similar hybrid system is not always fully commercially feasible. However, a pure pumped-storage system proved to be technically feasible and assisting the grid. The whole project analysis determines that such a system boosts the operational stability of the grid, increases the penetration of renewable energy systems and reduces the energy import. In addition, 15,100,000 tons of CO2-equivalent is estimated as annual emissions reduction in this study.

description: Report Introduction: For many years the U.S. Department of Agriculture has published estimates of the aggregage amount of taxes levied on farm personal property. The first publication of these estimates, in the Agricultural Finance Review of May 1941, showed the annual estimates for 1924 through 1939. Estimates of farm personal property taxes have been published annually since 1941. These estimates have proved useful primarily in evaluating the net income position of farmers and of various types of farming enterprises. In addition, information about taxes levied on agricultural personalty is essential in evaluating questions of State and local tax policy. It is pertinent to questions of tax equity and of the economic effects of various methods of financing State and local governments. Up to the present time only the annual estimates of the total of all taxes levied on farm personal property in the United States have been published. This single annual total has been inadequate for many purposes. This report provides more detailed estimates by States and, where data permit, by components of the farmers' personal property tax base. It also describes the method used in estimating farm personal property taxes. The economic effects of these levies are not considered in this report but will be analyzed in a subsequent publication.

description: Excerpts from the report: The national farm population dropped from 14,313,000 in 1962 to 13,367,000 in 1963, in a continuation of the downward trend that has prevailed since 1947. The decrease affected all nine major geographic divisions of the Nation. In 1963 each of three divisions (East North Central, West North Central, and South Atlantic) had about 2.5 million farm residents; the others less. An estimated 1,438,000 persons of all ages moved from farms during the preceding year or lived on places that ceased to be farms and consequently were removed from the farm category in 1963. This loss was countered in part by the movement to farms of about 352,000 people, leaving an estimated net loss to the farm population through outmovement and reclassification of 1,086,000 persons for the year.

description: Let X be a closed equidimensional local complete intersection subscheme of a smooth projective scheme Y over a field, and let Xt denote the t-th thickening of X in Y. Fix an ample line bundle OY(1) on Y. We prove the following asymptotic formulation of the Kodaira vanishing theorem: there exists an integer c, such that for all integers t⩾ 1 , the cohomology group Hk(Xt,OXt(j)) vanishes for k< dim X and j< - ct. Note that there are no restrictions on the characteristic of the field, or on the singular locus of X. We also construct examples illustrating that a linear bound is indeed the best possible, and that the constant c is unbounded, even in a fixed dimension.

description: One of the fastest deployments of the Department of Science and Technology – Philippine Institute of Volcanology and Seismology Quick Response Team (DOST-PHIVOLCS QRT) took place after the 27 July 2022 Magnitude (Mw) 7.0 Northwestern Luzon Earthquake. Aside from surveys and assessment of earthquake impacts, the DOST-PHIVOLCS QRT also conducted earthquake information dissemination and education for local government units (LGUs) and other residents in the affected areas to lessen their fear. Activities that engaged our stakeholders include courtesy calls, briefings and meetings with different LGUs, media interviews, community lectures, and the production of information materials such as the earthquake primer and poster, infographics, and videos posted on the DOST-PHIVOLCS official website and social media accounts. As we follow the health and safety protocols brought about by the COVID-19 pandemic, different strategies were implemented in the field and we have to quickly adapt to these. Daily situational briefings in the Abra Emergency Operation Center, streamed live on their official Facebook Page, allowed us to discuss our daily activities, hazard assessments, and recommendations with a broader audience. Reports of ground fissures and landslides and requests for evaluation were also discussed during the daily briefing and were adequately addressed by the DOST-PHIVOLCS QRT. Geologic terms such as liquefaction, sand boil, lateral spread, fissure, tension crack, and earthquake-induced landslide were also emphasized and have gotten media mileage. The science behind these phenomena was well communicated through media coverage which resulted in high appreciation and awareness. The use of social media in presenting the DOST-PHIVOLCS assessments has also reached not only the affected communities but also the rest of the country and other international organizations. A summary of the field investigation was disseminated to LGUs and other government agencies through exit presentations and poster turnovers. Close coordination and partnership with the different stakeholders resulted in a smooth investigation and effective information dissemination by the DOST-PHIVOLCS QRT.

description: Excerpts from the report Summary: Local economic benefits of watershed projects arise from two major sources: (1) net primary income, or increases in net incomes of the direct recipients of products and services from the projects, and (2) net secondary income, or increases in net incomes of other local people through multiplier effects of the primary income. Local primary income has been estimated by the Soil Conservation Service in the process of project planning. Practical methods for making reliable estimates of local secondary income in the planning process are yet to be developed. This study represents an initial step in research to devise these methods. Emphasis in the study is on increasing understanding of the economic processes which generate local secondary income and on estimating ratios of secondary to primary income for one local area. This study was conducted in Roger Mills County, Okla., where 90 of the 130 planned structures for upstream flood protection were complete by January 1963. For purposes of this study, net primary and net secondary incomes from watershed projects were expressed in terms of disposable income to recipients. The study excluded estimation of primary benefits, which were unnecessary for ascertaining the ratios of secondary to primary income. Instead, the procedure was to determine the interdependent relations among sectors of the local economy; then, the income ratios could be estimated directly. The indirect effects of agricultural and of recreational income from the projects in Roger Mills County were compared.
description: This publication presents results of one phase of a program of economic investigations on upstream watershed development in the Washita River Basin of Oklahoma. The program is a cooperative undertaking between the Economic Research Service, U. S. Department of Agriculture, and the Department of Agricultural Economics, Oklahoma Agricultural Experiment Station. This study of the Washita River Basin is part of a larger program of investigations of Watershed Protection and Flood Prevention being carried out through an agreement between the Economic Research Service and the Soil Conservation Service.

description: Residual stresses are those stresses that remain in an object (in particular, in a welded component) even in the absence of external loading or thermal gradients. In some cases, residual stresses result in significant plastic deformation, leading to warping and distortion of an object. This paper investigates the prediction of residual stresses developed in shielded metal arc welding of high thickness DH32 (ASTM A131) steel plates through Finite Element Simulation and experiments. To evaluate the residual stresses in weldment, conventional strain gauges are used. These stresses are developed on the Butt joint and T joint. The geometry of the T joint and butt?welded Low Carbon Steel (ASTM A131) plates was modeled and the residual stresses were simulated using ANSYS V19.2. Sequentially coupled transient thermal-mechanical, three?dimensional finite element models were developed and the Element Birth and Death Technique was used in simulation to evaluate the stresses in simulation. The conventional strain gauges are placed in different weld zones and the obtained results from these gauges are different as per the FE results. These results show that the residual stresses obtained by prediction from the finite element method are in fair agreement with the experimental results. Based on this, it can be concluded that how far we can use the strain gauges used in the measurement of residual stresses. and also the Finite Element Model can be used to replicate and determine the expected residual stresses that would be generated before an actual welding process is carried out.

description: The variations in the contents of tea catechins and free amino acids in relation to the quality of Fenghuang Oolong teas (FOT) were determined. It demonstrated that in FOT, which were grown at a high altitude, the contents of methylated estered tea catechins were relatively higher. By human flora-associated (HFA) mice model, the effect of FOT on high-fat diet-induced obesity was investigated by high-throughput sequencing. The shifts in relative abundance of the dominant taxa at the phylum, family and genus levels showed their dramatically effects. A large increase in Bacteroidetes with decrease of Firmicutes was observed after the administration of FOT for 8 weeks. Together, these results suggest that FOT are rich in tea catechins, especially O-methylated tea catechin derivatives, which may be affected by the unique growth environment, and FOT may have prebiotic-like activity and can be used as functional food components in manipulating intestinal microbiota.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: For a local complete intersection subvariety X = V (I) in ℙn over a field of characteristic zero, we show that, in cohomological degrees smaller than the codimension of the singular locus of X, the cohomology of vector bundles on the formal completion of ℙn along X can be effectively computed as the cohomology on any sufficiently high thickening Xt = V (It); the main ingredient here is a positivity result for the normal bundle of X. Furthermore, we show that the Kodaira vanishing theorem holds for all thickenings Xt in the same range of cohomological degrees; this extends the known version of Kodaira vanishing on X, and the main new ingredient is a version of the Kodaira- Akizuki-Nakano vanishing theorem for X, formulated in terms of the cotangent complex.

description: Previous versions of sparse principal component analysis (PCA) have presumed that the eigen-basis (a p × k matrix) is approximately sparse. We propose a method that presumes the p × k matrix becomes approximately sparse after a k × k rotation. The simplest version of the algorithm initializes with the leading k principal components. Then, the principal components are rotated with an k × k orthogonal rotation to make them approximately sparse. Finally, soft-thresholding is applied to the rotated principal components. This approach differs from prior approaches because it uses an orthogonal rotation to approximate a sparse basis. One consequence is that a sparse component need not to be a leading eigenvector, but rather a mixture of them. In this way, we propose a new (rotated) basis for sparse PCA. In addition, our approach avoids “deflation” and multiple tuning parameters required for that. Our sparse PCA framework is versatile; for example, it extends naturally to a two-way analysis of a data matrix for simultaneous dimensionality reduction of rows and columns. We provide evidence showing that for the same level of sparsity, the proposed sparse PCA method is more stable and can explain more variance compared to alternative methods. Through three applications—sparse coding of images, analysis of transcriptome sequencing data, and large-scale clustering of social networks, we demonstrate the modern usefulness of sparse PCA in exploring multivariate data. An R package, epca, and the supplementary materials for this article are available online.

description: This case study details the integration of an online grading platform in a Calculus program. Initially implemented to increase the efficiency and quality of grading written assessments in a large undergraduate program, the effects were many and surprising. Two main concerns surfaced that we needed to address, namely: • consistency in grading; • quality of feedback to students to facilitate learning. With greater course coordination and the use of the online grading platform for homework and exams, student success in Calculus and retention of students continuing from Calculus I to II dramatically improved over the past 2 years.
