Direct formulation and algorithms for the probit-based stochastic user equilibrium traffic assignment problem

ABSTRACT This paper proposes simple and direct formulation and algorithms for the probit-based stochastic user equilibrium traffic assignment problem. It is only necessary to account for random variables independent of link flows by performing a simple transformation of the perceived link travel time with a normal distribution. At every iteration of a Monte-Carlo simulation procedure, the values of the random variables are sampled based on their probability distributions, and then a regular deterministic user equilibrium assignment is carried out to produce link flows. The link flows produced at each iteration of the Monte-Carlo simulation are averaged to yield the final flow pattern. Two test networks demonstrate that the proposed algorithms and the traditional algorithm (the Method of Successive Averages) produce similar results and that the proposed algorithms can be extended to the computation of the case in which the random error term depends on measured travel time.
The Role of Environmental, Social, Governance (ESG) Practices and Ownership on Firm Performance in Emerging Markets

ABSTRACT This paper investigates: (i) the effect of environmental, social, and governance (ESG) engagement and ownership attributes on firm performance and (ii) whether different ownership attributes (institutional, foreign, and state ownership) moderate the association between ESG engagement and firm performance. Employing an extensive sample from 22 emerging countries worldwide, we provide cross-country evidence that ESG engagement and its three pillars, i.e. environmental, social, and governance pillars, enhance firm performance, proxied with ROA and Tobin’s Q. Moreover, institutional and foreign ownership positively impact firm performance. We present novel evidence that the positive impact of superior ESG engagement on firm performance is lower for higher institutional ownership companies than lower institutional ownership companies, but greater for higher foreign ownership companies than lower foreign ownership companies.
A Diagnostic Study of Interaction of Cumulus Updrafts and Downdraf is with Large-Scale Motions in GATE

A diagnostic method including cumulus updrafts and downdrafts is applied to GATE A/B-scale upper-air observations for Phase III to study the interaction of the cumulus convection with large-scale motions. Average results for Phase III show that the mass fluxes for deep and shallow clouds are larger than those for clouds with tops in the middle troposphere and downward mass fluxes equivalent to 40%*50% of updrafts convective mass fluxes are accomplished by cumulus downdrafts. Correlation coefficients between deep, middle and shallow cloud mass fluxes and the large-scale vertical velocity are computed to examine the response of cumulus clouds to the large-scale forcing. The results show that deep clouds are highly correlated with the largescale vertical velocity at all levels, middle clouds have little correlations and shallow clouds are correlated only with the vertical velocity near cloud base. Maximum activity of deep clouds occurs nearly at the same time as maximum large-scale upward motion at higher levels but about 6 h after maximum low-level convergence. Strongest downdraft mass fluxes occur corresponding to maximum deep cloud activity. Shallow cloud mass fluxes have negative correlations with the low-level convergence indicating that shallow cloud activity is weak when the low-level convergence is large. A compositing method is used to clarify relationships between the cumulus convection and the African wave disturbance observed during GATE. Maximum deep cloud mass flux is found in the region near the wave trough where the large-scale vertical velocity has a peak. This is also the region where largest downdraft cloud mass fluxes exist. Shallow cloud activity is weak near the wave trough but strong near the wave ridge. Weak subsidence with amplitude of a few mb h-1 is present nearly everywhere in the environment of the clouds in the wave disturbance, but slightly larger subsidence occurs in the regions where shallow cloud mass fluxes dominate.
Convection driven by temperature and composition flux with the same diffusivity

Temperature, pressure, and composition determine density of fluids within the earth, the ocean, our atmosphere, stars and planets. In some cases, variation of composition component C competes equally with temperature T to determine buoyancy-driven flow. Properties of two-dimensional cellular convection are calculated with density difference between top and bottom boundaries determined by difference of temperature T (Dirichlet boundary conditions, quantified by Rayleigh number Ra that is positive destabilising), fluxes of C (Neumann boundary conditions quantified by Raf that is positive stabilising), and Prandtl number Pr. Numerical solutions in a 2-dimensional rectangular chamber are analysed for Prandtl numbers . For Ra and and Raf above approximately 300, subcritical instability separates T-driven convection from C-dominated stagnation. The flow is steady but a sudden change in Ra or Raf produces decaying pulsations to the new flow. A boundary layer solution for rapid flow exists in which T, which has the Dirichlet condition, is more sensitive to flow speed than C with the Neumann condition. A new type of pulsating flow occurs for Ra and . The pulsations are characterised by slow flow with gradually strengthening compositional plumes in a thermally stratified flow interrupted by rapid flow with gradually weakening compositional plumes. In this slow speed range, C is more sensitive to speed than T.

Gambling Prevalence and Factors Associated with Gambling Participation among University Students in Uganda

This paper examines the prevalence of gambling for gain among university students and to gain a theory-based understanding and knowledge of the influence factors of this gambling behaviour based on the University Student Psychosocial Problems Development Theory (USPPDT). Relatively little is known about the factors associated with students’ gambling for financial gain encompassing a student’s biosocial/cultural and psycho characteristics informed by a theory. Participants were recruited from two public and three private universities in Uganda. A total of 1101 randomly selected students participated in the study and 976 (88.6%) completed the survey instruments. The self-reported current prevalence of gambling participation was 281 (28.8%) among university students (≥ 19 years). In agreement with the theory and findings from the study, student demographic characteristics, study program characteristics, student-related health burden characteristics, psychosocial functioning, and antisocial behaviour items were particularly predictive of students’ participation in gambling for financial gain. These risk factors for gambling are not presumed as causation, identifying them points to important implications in terms of prevention and intervention on student gambling behaviour. This points to a considered interplay of different players in designing transversal strategies for a student at risk for gambling.
Benefits of Working from Home During the COVID-19 Pandemic for Undiagnosed Workers with Attention-Deficit/Hyperactivity Disorder Symptoms

Purpose Our previous study suggested that working conditions might impact work productivity amid the COVID-19 pandemic. This study aimed to investigate the association between working from home (WFH) and depressive symptoms, work productivity, and quality of life (QOL), in undiagnosed workers with attention-deficit/hyperactivity disorder (ADHD) symptoms during the COVID-19 pandemic. Methods During the pandemic, the survey was conducted among eligible workers with (N = 904) and without (N = 900) ADHD symptoms based on the Adult ADHD Self-Report Scale [ASRS]. Each group was further stratified by working conditions (full working on-site [FWOS], hybrid, full WFH [FWFH]). Two-way ANOVA was performed to investigate the impact of WFH on depressive symptoms (Patient Health Questionnaire [PHQ-9] score), work productivity (Work Productivity and Activity Impairment scale [WPAI] scores), and QOL (EuroQol 5-Dimensions 5-Levels [EQ-5D-5L] score). The Tukey–Kramer test was used to assess differences between the stratified subgroups. Poisson and multiple regression analyses were also performed to assess the factors associated with these outcomes. Results Other than PHQ-9 score between FWOS and hybrid work in workers with ADHD symptoms (p < 0.05), no significant differences were observed in outcomes among the working condition subgroups in both workers with and without ADHD symptoms. In workers with ADHD symptoms, hybrid work and FWFH were significantly associated with a lower PHQ-9 score (hybrid, p < 0.001; FWFH, p < 0.05) but neither were significantly associated with WPAI score nor EQ-5D-5L. Annual income and discretionary work were significantly associated with a lower PHQ-9 score and a higher EQ-5D-5L score in workers with ADHD symptoms. Job type (manufacture/construction) was significantly associated with a lower presenteeism score. Conclusion WFH (hybrid and FWFH) may be associated with lower depressive symptoms compared with FWOS in undiagnosed workers with ADHD symptoms. The findings may be useful when considering suitable working environments for workers especially with ADHD symptoms.
Experimental studies and simulations of hydrogen pellet ablation in the stellarator TJ-II

Plasma core fuelling is a key issue for the development of steady-state scenarios in large magnetically-confined fusion devices, in particular for helical-type machines. At present, cryogenic pellet injection is the most promising technique for efficient fuelling. Here, pellet ablation and fuelling efficiency experiments, using a compact pellet injector, are carried out in electron cyclotron resonance and neutral beam injection heated plasmas of the stellarator TJ-II. Ablation profiles are reconstructed from light emissions collected by silicon photodiodes and a fast-frame camera system, under the assumptions that such emissions are loosely related to the ablation rate and that pellet radial acceleration is negligible. In addition, pellet particle deposition and fuelling efficiency are determined using density profiles provided by a Thomson scattering system. Furthermore, experimental results are compared with ablation and deposition profiles provided by the HPI2 pellet code, which is adapted here for the stellarators Wendelstein 7-X (W7-X) and TJ-II. Finally, the HPI2 code is used to simulate ablation and deposition profiles for pellets of different sizes and velocities injected into relevant W7-X plasma scenarios, while estimating the plasmoid drift and the fuelling efficiency of injections made from two W7-X ports.

Oscillations in age-structured models of consumer-resource mutualisms

In consumer-resource interactions, a resource is regarded as a biotic population that helps to maintain the population growth of its consumer, whereas a consumer exploits a resource and then reduces its growth rate. Bi-directional consumer-resource interactions describe the cases where each species acts as both a consumer and a resource of the other, which is the basis of many mutualisms. In uni-directional consumer-resource interactions one species acts as a consumer and the other as a material and/or energy resource while neither acts as both. In this paper we consider an age-structured model for uni-directional consumer-resource mutualisms in which the consumer species has both positive and negative effects on the resource species, while the resource has only a positive effect on the consumer. Examples include a predator-prey system in which the prey is able to kill or consume predator eggs or larvae and the insect pollinator and the host plant relationship in which the plants provide food, seeds, nectar and other resources for the pollinators while the pollinators have both positive and negative effects on the plants. By carrying out local analysis and bifurcation analysis of the model, we discuss the stability of the positive equilibrium and show that under some conditions a non-trivial periodic solution through Hopf bifurcation appears when the maturation parameter passes through some critical values.
Influence of the Zonal Harmonics of the Primary on L 4,5 in the Photogravitational ER3BP

We investigate in the framework of the elliptic restricted three-body problem (ER3BP), the influence of the zonal harmonics (J2 and J4) of the primary and the radiation pressure of the secondary on the positions and stability of the triangular equilibrium points. The triangular points of the problem are affected by the parameters involved in the systems’ dynamics. The positions change with increase in the zonal harmonics, eccentricity and radiation pressure. The triangular points remain stable in the interval 0 c     as shown arbitrarily.
Thermostable alkaline protease from Scytalidium thermophilum: production, purification, and biochemical characterization

Abstract An extracellular alkaline protease from Scytalidium thermophilum was produced in a glucose-containing medium supplemented with 5 mM NaCl for 3 days at pH 8.0 and 45 °C. The enzyme was 10-fold purified using ammonium sulfate precipitation followed by ion-exchange chromatography, and its molecular weight was calculated as 80 kDa from SDS-PAGE. The enzyme exhibited optimum activity at pH 8.0 and 60 °C. It was stable at pH and temperature range of 6.0–10.0 and 30–80 °C, respectively. Its half time was 30 h at pH 6.0, 7.0 and 8.0, while those were 22, 16, 8, and 3 h at 50 °C, 60 °C, 70 °C, and 80 °C, respectively. Kinetic parameters including Km (2 ± 0.02 mg/ml), Vmax (18.7 ± 1.5 µmole tyrosine ml−1 min−1), and kcat (2.5 x 103 min−1) were determined using casein. Ca2+ increased the enzyme activity, but it was slightly reduced by EDTA, Triton X-100, Tween 20, and Tween 80. It was active against reducing agents like β-mercaptoethanol but completely inhibited by phenyl methyl sulphonyl fluoride supporting the enzyme belonging to the serine protease family. Chloroform (143%), methanol (138%), and isopropanol (111%) increased the enzyme activity at 5% (v/v), while ethanol (71%) and acetone (81%) moderately reduced the proteolytic activity at the same concentration. Dimethyl sulfoxide (5%, v/v) did not significantly affect the enzyme. The enzyme was compatible with several detergents (1%, w/v), maintaining more than 90% of its original activity in almost all detergents tested. The stability of the enzyme presented against pH, temperature, organic solvents, and detergents indicates its potential use in various industrial applications, especially in peptide synthesis and the laundry industry.

Impact of Plantar Fasciitis on Foot-Specific and Generic Health-Related Quality of Life in King Khalid University Hospital, Saudi Arabia

Objectives The objective is to assess the extent of foot-specific and generic health-related quality of life (HRQoL) impairment among individuals diagnosed with plantar fasciitis (PF) at King Khalid University, Saudi Arabia, and to determine the influence of various sociodemographic and clinical factors. Methods In this cross-sectional study, we administered an online survey from March to June 2023 to patients with PF at King Khalid University Hospital. This questionnaire covered sociodemographic, and clinical characteristics, and included the translated Foot Health Status Questionnaire (FHSQ). Further, patient data were obtained from hospital records between 2016 and 2023 using the E-SIHI system. Results We recruited 209 patients for the study. Lower FHSQ scores were found in unemployed and low-income participants indicating a worse quality of life (QoL) in the Foot Pain domain, while those aged over 40 years and with low income showed greater impairment in the General Foot Health domain. No single factor influenced the Foot Function or Footwear domains. Worse General Health and Physical Activity scores were associated with low-education and low-income participants and those who did not exercise. Women exhibited a lower QoL than men in all domains except for General Health. Conclusion The QoL of Saudi women with PF was similar to that of women in other countries. However, the patients in the present study reported poorer footwear scores but better General Health scores. Therefore, focusing more on proper footwear-related treatments may help improve the QoL of patients with PF.
Quality Indicators of pediatric polytrauma care

Background: Polytrauma is still the major cause of death in children all over the world. Initial evaluation and management should be approached by teamwork that includes pediatric physicians, pediatric intensive care physicians, and trauma surgeons. Trauma care provides injured children with life-and limb-saving treatment, but it is unclear if the proper tools have been developed to measure the quality of care delivered. Objective: To review quality indicators for evaluating care delivered to pediatric polytrauma patients aged ≤ 12 years and illustrate various complaints, shortages, suggestions, and possible solutions in the management of children at Aljalla Trauma Hospital–Benghazi/Libya. Methods: This study was conducted during a period of the Benghazi War (From July 2015 to July 2016). A retrospective records review of 228 children admitted as PPPs was done. All types of injury were included with a focus on the hospital stage of PPPs management. A questionnaire form for evaluation of the quality indicators of emergency management of pediatric polytrauma patients was prepared and filled out by the staff in charge. Results: The questionnaire has been answered by 93 of the staff who work in an adult emergency room, adult intensive care unit, and trauma surgeons. Our results enhance the findings of epidemiological studies for musculoskeletal injuries in PPPs and positively confirm the need to establish educational courses and continuous evaluation of performance for personage included in pediatric polytrauma patients management. Conclusion: Trauma centers may not have the resources to care for all the injured children within their referral region at any given time, and pediatric trauma centers should serve as referral points in major urban areas.
