Critical Success Factors for Enterprise Resource Planning Systems from the Stakeholders’ Perspective: The Case of Jordan

This study is motivated by the high failure rate of enterprise resource planning (ERP). An analysis is conducted of the numerous studies that have attempted to explore factors that may lead to success in ERP. A descriptive, quantitative, and qualitative approach was used to examine the critical success factors (CSFs) and their effect on emerging ERP success in public and large private organizations in Jordan. The overall findings of this study indicate that the CSFs for ERP in the private sector are totally different from those in the public sector and that various stakeholders have different opinions regarding these factors.
Critical Role of Molecular Packing in Lo Phase Membrane Solubilization

Membrane solubilization induced by Triton X-100 (TX-100) was investigated. Different membrane compositions and phase states were studied along the detergent titration. Expected solubilization profiles were obtained but new information is provided. The fluorescence of nitrobenzoxadiazole (NBD)-labeled lipids indicates that the liquid-ordered (Lo)/liquid-disordered (Ld) phase coexistence is barely unaffected at sub-solubilizing detergent concentrations and highlights the vesicle-to-micelle transition. Moreover, the location of the NBD group in the bilayer emphasizes a detergent–membrane interaction in the case of the insoluble Lo phase membrane. It has also been shown that the molecular packing of the membrane loosens in the presence of TX-100, regardless of the solubilization profile. Motivated by studies on GPMVs, the solubilization of less ordered Lo phase membranes was considered in order to improve the effect of molecular packing on the extent of solubilization. Membranes composed of SM and Chol in an equimolar ratio doped with different amounts of PC were studied. The more ordered the Lo phase membrane is in the absence of detergent, the less likely it is to be solubilized. Furthermore, and in contrast to what is observed for membranes exhibiting an Lo/Ld phase coexistence, a very small decrease in the molecular packing of the Lo phase membrane radically modifies the extent of solubilization. These results have implications for the reliability of TX-100 insolubility as a method to detect ordered domains.
Development and application of an adjoint-based optimal flow control framework for compressible direct numerical simulations

The advances in the understanding of compressible turbulent flows challenge researchers to tackle more ambitious problems that surpass human intuition. Hence, it becomes necessary to rely on methods that give an insight into the underlying physical mechanisms that govern these turbulent flows to perform non-trivial tasks such as flow control. This thesis describes the development and application of an adjoint-based optimal flow control framework for compressible flows, which has been appended to an existing in-house DNS code (HiPSTAR). With minor coding effort, this framework is extended to permit the computation of both (stable and unstable) exact steady and periodic flow solutions in compressible flows over complex geometries. In this work we present for the first time a family of exact periodic solutions in compressible flows (Re = 2000), which we study in detail, paying special attention to the flow-acoustic interaction characteristic from cavity flows. Furthermore, a family of equilibrium flow solutions associated to these periodic orbits is also introduced, where it is shown that both families meet at the quasi-incompressible Mach number range. A stability analysis of both periodic and equilibrium solutions shows that the bifurcation is of subcritical Hopf type. Moreover, this flow-acoustic interaction is optimally controlled in a cavity flow of a higher Reynolds number (Re = 5000) by using the adjoint-based optimal flow control framework. The target of the flow actuation consists in reducing noise levels at the sensor location, by either reducing the overall sound radiation or altering the sound directivity. Lastly, we also carry out adjoint-based optimal flow control on a three-dimensional backward-facing step flow (Re = 3000). The investigation is oriented to cabin noise reduction, where we optimise an upstream flow actuation to reduce the flow impinging scales which present the largest impact on cabin noise. In addition, the complexity present in the flow studied pushes the adjoint-based approach at its limits. These intrinsic limitations of the method are discussed, where we also suggest and demonstrate a successful alternative which permits the use of adjoint-based optimisation methods in separated flows.
Effect of Dam Body Conformations on Birth Traits of Calves in Chinese Holsteins

Simple Summary The birth traits of calves are directly related to the economic benefits of the dairy farm. Predicting the birth traits of calves before they are born will benefit the breeding of cows and reduce the potential loss of pasture. Conformation traits are closely related to the reproduction of dairy cows. The objective of the present study was to examine the associations among birth traits and conformation traits in Chinese Holstein dairy cows, in order to provide a reference for understanding the birth traits of calves in advance by using the conformational traits of dam cows. In this study, we analyzed the relationship between female structure traits and calf birth traits by logistic regression and multiple comparisons. We found that there was a significant correlation between the two, which could predict the birth traits of calves to a certain extent by the body conformation traits of dams. Abstract The objective of this study was to explore the effect of dam body conformations on birth traits including stillbirth, dystocia, gestation length and birth weight of Chinese Holstein calves and to provide a reference for improving cow reproductive performance. We collected phenotype data on 20 conformation traits of Chinese Holstein cows and analyzed the impact of dam conformation trait linear scores on stillbirth, dystocia, gestation length and calf birth weight. The feet angle, set of rear legs, fore udder attachment and rear attachment height traits of the dairy cows significantly affected the risk of stillbirth. The risk of dystocia decreases with the increase in stature and pin width. The bone quality of dairy cows had a significant positive correlation with gestation length. There was a significant positive correlation between fore udder attachment and calf weight at birth. The birth weight of calves from cows with high body conformation traits was significantly higher than that of calves with a low composite score. These results suggest that improving the body conformation traits, especially the selection of mammary system and body shape total score, will be beneficial in improving the reproductive performance of dairy cows.
Hybrid Analytical Model for Predicting the Electromagnetic Losses in Surface-Mounted Permanent-Magnet Motors

This article presents a comprehensive method to predict the electromagnetic losses in surface-mounted permanent-magnet (PM) motors based on a hybrid analytical model (HAM). HAM will significantly improve the calculation speed compared with finite-element method (FEM) while keeping great accuracy, making it a competitive alternative for the analysis and optimization of PM motors. As the accurate field distribution is the bias of electromagnetic losses prediction, the magnet loss, sleeve loss, and copper loss can all be accurately obtained from their vector potential distribution using HAM with small computational burden. As for iron loss, the improved Jiles–Atherton (JA) model is proposed to build the relationship between the loss and the magnetic field in the iron region from the perspective of energy conversion. The predictions of magnet loss, sleeve loss, and copper loss using HAM agree well with the FEM. The experiment on surface-mounted PM prototype demonstrates the high accuracy of iron loss calculation using the combination of the improved JA model and HAM.
Willingness to Pay for Centralized Modern Locust Bean Processing Equipment in Ekiti State, Nigeria

This study investigated the propensity to pay for modern apparatus processing locust beans in Ekiti State, Nigeria. Utilizing primary data and a multistage sampling strategy, 240 processors were chosen for the study. The collected data were analyzed utilizing descriptive statistics and an inferential statistical instrument, such as Logit and ordinary least square regression analysis. About 72 percent of processors were married and had an average of eight years of experience processing locust legumes. The majority of respondents belonged to a cooperative group (66.7%) and had no access to credit (100%). The average monthly income from processing was N18,000. The majority of respondents (65%) were unwilling to pay for the service of centralized, advanced or contemporary processing equipment. According to the results of the Logit regression analysis, the variables that significantly influence willingness to pay for the service of centralized modern locust bean processing equipment were household income and processing experience (1%), level of education and age (5%), and household size (10%). The Ordinary Least Square (OLS) analysis reveals that household size and education level were significant at the 1% level, while age and marital status were significant at the 5% level and processing experience was significant at the 1% level. The study suggests that processors ready to pay should form a formidable cooperative to secure grants or loans to establish a centralized, contemporary locust processing cottage. The government should educate processors on modern food processing and safety at all levels.
Global modeling of the low‐ and middle‐latitude ionospheric D and lower E regions and implications for HF radio wave absorption

We compare D and lower E region ionospheric model calculations driven by the Whole Atmosphere Community Climate Model (WACCM) with a selection of electron density profiles made by sounding rockets over the past 50 years. The WACCM model, in turn, is nudged by winds and temperatures from the Navy Operational Global Atmospheric Prediction System‐Advanced Level Physics High Altitude (NOGAPS‐ALPHA). This nudging has been shown to greatly improve the representation of key neutral constituents, such as nitric oxide (NO), that are used as inputs to the ionospheric model. We show that with this improved representation, we greatly improve the comparison between calculated and observed electron densities relative to older studies. At midlatitudes, for both winter and equinoctal conditions, the model agrees well with the data. At tropical latitudes, our results confirm a previous suggestion that there is a model deficit in the calculated electron density in the lowermost D region. We then apply the calculated electron densities to examine the variation of HF absorption with altitude, latitude, and season and from 2008 to 2009. For low latitudes, our results agree with recent studies showing a primary peak absorption in the lower E region with a secondary peak below 75 km. For midlatitude to high latitude, the absorption contains a significant contribution from the middle D region where ionization of NO drives the ion chemistry. The difference in middle‐ to high‐latitude absorption from 2008 to 2009 is due to changes in the NO abundance near 80 km from changes in the wintertime mesospheric residual circulation.
A Systematic Review of the Inter-individual Differences in Avoidance Learning

Avoidance is typically adaptive given it prevents threat. However, avoidance becomes maladaptive when it is executed out of proportion of threat (i.e., excessive or insufficient avoidance), persists in the absence of threat, or excessively generalizes to other innocuous situations. Although there has been an increase in research in these different processes of maladaptive avoidance, the role of inter-individual differences in these avoidance processes receives less research attention, despite its theoretical and clinical importance. In this systematic review, we summarized the role of inter-individual traits that relate to risk or resilient factors for anxiety-related disorders, trauma-and stressor-related disorders, obsessive-compulsive related disorders, pain related disorders, eating-related disorders, and affective disorders. A majority of the inter-individual differences had an apparent mixed or null effect on the different processes of avoidance. We discussed this lack of evidence of inter-individual differences on avoidance due to a lack of methodological and/or analytical consensus in the field, in addition to a lack of integration of recent findings into existing theories. Recommendations for future research are discussed, with a focus on examining the conditions or experimental parameters for certain inter-individual traits to manifest their effects on avoidance, identifying the nuances of methodological and/or inter-individual differences in avoidance, and a call for integrating recent preliminary findings into existing theories.
Unlocking Undergraduate Student Success: A Study of High-Impact Practices in a Comprehensive and Diverse College

This study examines undergraduate senior students’ participation in high-impact practices (HIPs) and the relationship of that participation with engagement indicators, perceived gains, and overall satisfaction, as well as institutional outcomes of persistence and graduation based on race/ethnicity, first-generation status, and low-income status. Drawing on multiple years of data from 1,482 undergraduate seniors who completed the 2015 through 2019 National Survey of Student Engagement (NSSE) and enrolled in a comprehensive four-year state college, this study indicates that HIP participants reported higher levels of engagement, perceived gains, and overall satisfaction. Participation in HIPs is also positively related to improved persistence or graduation, particularly for racially minoritized students. While overall participation patterns were similar regardless of race/ethnicity or first-generation status, low-income students had higher participation rates in HIPs and participated in more kinds of HIPs as compared to their non-low-income counterparts. Implications of implementing and increasing access to HIPs for enhancing student success in similar institutions are discussed.
Behavioral descriptions pretested for racial stereotypicality and valence: Data from an American and a Portuguese sample

In social psychology research, there are several kinds of stereotypical materials that can be used – faces, videos, lists of words, attributes. However, when it comes to behavioral sentences, there is a lack of pre-tested racial stimuli available in the literature. To fill the gap, this paper provides two lists of 154 short behavioral sentences, with stereotypicality (white to black) and valence (negative to positive) ratings. The first list was pre-tested with an American sample (Study 1), while the second list was pre-tested with a European Portuguese sample (Study 2). Importantly, this paper focuses on the broader meaning of black stereotypes’ and not just the narrower definition of the African American stereotype, whose differences are discussed. T-tests identified 73 and 118 stereotypical behavioral descriptions, for future use, respectively for the American and European Portuguese samples. Additional comparisons within and between samples are also provided. Full behavioral descriptions, along with pertinent statistical data, are available to the reader, as a useful working instrument for future research.
Plant–Microbes Interaction: Exploring the Impact of Cold-Tolerant Bacillus Strains RJGP41 and GBAC46 Volatiles on Tomato Growth Promotion through Different Mechanisms

Simple Summary Microbial volatile organic compounds (VOCs) play a crucial role in promoting plant growth and causing systemic resistance to a variety of diseases caused by fungus, bacteria, nematodes, and oomycetes. However, the role of Bacillus VOCs in growth promotion is still limited. In the present work, we aim to examine the growth promotion mechanisms of cold-tolerant Bacillus strains RJGP41 and GBAC46 from the Qinghai-Tibet Plateau and the well-known PGPR strain FZB42 and their VOCs on tomato plants. Our experiment results revealed that both Bacillus isolates and their pure VOCs positively improve PGPR activities in tomato plants by triggering antioxidant enzyme activity and expression of the PGPR genes. In our future research, the selected Bacillus strains and their novel pure VOCs will be further explored to find the possible mechanisms for the safe and green control of tomato disease in sustainable agriculture. Abstract The interaction between plant and bacterial VOCs has been extensively studied, but the role of VOCs in growth promotion still needs to be explored. In the current study, we aim to explore the growth promotion mechanisms of cold-tolerant Bacillus strains GBAC46 and RJGP41 and the well-known PGPR strain FZB42 and their VOCs on tomato plants. The result showed that the activity of phytohormone (IAA) production was greatly improved in GBAC46 and RJGP41 as compared to FZB42 strains. The in vitro and in-pot experiment results showed that the Bacillus VOCs improved plant growth traits in terms of physiological parameters as compared to the CK. The VOCs identified through gas chromatography-mass spectrometry (GC-MS) analysis, namely 2 pentanone, 3-ethyl (2P3E) from GBAC46, 1,3-cyclobutanediol,2,2,4,4-tetramethyl (CBDO) from RJGP41, and benzaldehyde (BDH) from FZB42, were used for plant growth promotion. The results of the partition plate (I-plate) and in-pot experiments showed that all the selected VOCs (2P3E, CBDO, and BDH) promoted plant growth parameters as compared to CK. Furthermore, the root morphological factors also revealed that the selected VOCs improved the root physiological traits in tomato plants. The plant defense enzymes (POD, APX, SOD, and CAT) and total protein contents were studied, and the results showed that the antioxidant enzymes and protein contents significantly increased as compared to CK. Similarly, plant growth promotion expression genes (IAA4, ARF10A, GA2OX2, CKX2, and EXP1) were significantly upregulated and the ERF gene was downregulated as compared to CK. The overall findings suggest that both Bacillus isolates and their pure VOCs positively improved plant growth promotion activities by triggering the antioxidant enzyme activity, protein contents, and relative gene expressions in tomato plants.
Surgical Outcomes of Repairing Ebstein Anomaly: A Single-Center Experience

Background: Ebstein anomaly (EA) is a rare congenital disorder of the tricuspid valve (TV), accounting for about one percent of congenital heart defects. Considering highly variable anatomy, diverse corrective surgical methods are currently utilized. Cone reconstruction provides a near anatomic tricuspid restoration method that has triggered enthusiasm for early repair over recent years. Objectives: In the current study, we aimed to evaluate the clinical and echocardiographic features and outcomes of patients who underwent surgical correction of EA in our referral center. Methods: In this study, we reviewed the medical records of 35 patients with EA who underwent cone repair or TV replacement and had accessible echocardiographic data before and at least one year following the corrective surgery. The patients were evaluated for residual tricuspid regurgitation (TR) severity, right ventricular (RV) size, RV fractional area change (FAC), left ventricular end-systolic diameter (LVESD), left ventricular end-diastolic diameter (LVEDD), and 2D left ventricular ejection fraction (LVEF) before and after the operation. Results: Mean age of the patients was 29.49 ± 9.13 years, and 54.3% of them were female. Twenty-one (60%) patients underwent cone repair, and 14 were subjected to TV replacement. Seven (20%) patients required reoperation; redo TV repair was conducted in three patients (8.6%); two (5.7%) patients underwent biologic TV replacement; mechanical TV replacement was performed in one patient (2.9%) who had degenerative biologic TVs, and one patient (2.9%) was subjected to redo-operation due to mechanical TV malfunction. Positive changes in the means of RV-FAC and 2D-LVEF were statistically significant in all patients irrespective of the type of surgery (P < 0.001), but changes in the means of RV size (P = 0.38) and LVESD (P = 0.302) were not statistically significant. There was a significant increase in functional RV size in both groups of patients who underwent repair (P = 0.063) or replacement (P = 0.02). Conclusions: The present study revealed satisfactory post-op results for cone TV repair in patients with EA, evidenced by reduced TR severity and improved biventricular functional parameters. Assessing the durability of the outcomes of cone TV repair needs longer-term follow-ups.
基于MPS-FEM耦合方法对比研究刚性与弹性挡板对液舱晃荡的抑制作用@@@An MPS-FEM Coupled Method for the Comparative Study of Liquid Sloshing Flows Interacting With Rigid and Elastic Baffles

Fluid⁃structure interaction (FSI) problems caused by fluid impact loads are com⁃ monly existent in naval architectures and ocean engineering fields. For instance, the impact loads due to non⁃linear fluid motion in a liquid sloshing tank potentially affect the structural safety of cargo tanks or vessels. The challenges of numerical study on FSI problems involve not only multidisciplinary features, but also accurate description of non⁃linear free surface. A fully Lagrangian particle⁃based method , the moving particle semi⁃implicit and finite element coupled method (MPS⁃FEM), is developed to numerically study the FSI problems. Taking into account the advantage of the Lagrangian method for large deformations of both fluid and solid bounda⁃ ries, the MPS method is used to simulate the fluid field while the finite element method(FEM) to calculate the structure field. Besides, the partitioning strategy is employed to couple the MPS and FEM modules. To validate accuracy of the proposed algorithm, a benchmark case is numer⁃ ically investigated. Both the patterns of free surface and the deflections of the elastic structures are in good agreement with the experimental data. Then, the present FSI solver is applied to the comparative study of the mitigating effects of rigid baffles and elastic baffles on the sloshing motions and impact loads.
Cyberloafing and Employees' Reactions to Work Stress, Moderated by Job Satisfaction

Companies have a lot of worries about employees using the internet for personal reasons during work hours. Cyberloafing is the practise of using the Internet for personal purposes while at work. The purpose of this research is to ascertain if employees' levels of job satisfaction in Cikarang can mitigate the impact of job stress on cyberloafing. This study is a quantitative survey with as many as one hundred participants from all across Cikarang. The cyberloafing scale, job satisfaction survey, and general work stress scale are only few of the instruments used to collect data. Moderated Regression Analysis was used for the data analysis. The findings implicated work-related stress as a causal factor of cyberloafing. There was no buffering effect of job contentment between job stress and cyberloafing
