TL;DR: In this paper, the authors examined the determinants of corporate dividend policy in Jordan using Tobit specifications and found that the proportion of stocks held by insiders and state ownership significantly affect the amount of dividends paid.
Abstract: This paper examines the determinants of corporate dividend policy in Jordan. The study uses a firm‐level panel data set of all publicly traded firms on the Amman Stock Exchange between 1989 and 2000. The study develops eight research hypotheses, which are used to represent the main theories of corporate dividends. A general‐to‐specific modeling approach is used to choose between the competing hypotheses. The study examines the determinants of the amount of dividends using Tobit specifications. The results suggest that the proportion of stocks held by insiders and state ownership significantly affect the amount of dividends paid. Size, age, and profitability of the firm seem to be determinant factors of corporate dividend policy in Jordan. The findings provide strong support for the agency costs hypothesis and are broadly consistent with the pecking order hypothesis. The results provide no support for the signaling hypothesis.

TL;DR: Several functions of unliganded nVDR were discovered by studying human samples from patients having hereditary vitamin D resistant rickets, transgenic mice overexpressing the VDR and VDR knockout mice, and in vitro, vitamin D stimulates lipogenesis and inhibits lipolysis by interacting with mVDR.

TL;DR: The results support a hypothesis that defense mechanisms against reactive oxygen species are impaired in rheumatoid arthritis.
Abstract: In order to assess a possible role of the natural glutathione defense system in the pathogenesis of rheumatoid arthritis (RA), serum reduced glutathione levels (GSH), glutathione reductase (GSR), glutathione S-transferase (GST), glutathione peroxidase (GSH-Px) and alkaline phosphatase (ALP) activities, lipid peroxidation (MDA content) and indexes of inflammation were evaluated in 58 rheumatic patients. Rheumatoid athritis was associated with significant depletion (ca. 50%) in GSH levels compared with normal control subjects. Serum levels of the detoxifying enzymes GSR and GSH-Px decreased by ca. 50% and 45%, respectively, whereas a threefold increase in the activity of GST was observed. A 1.2-fold increase in ALP was observed in patients with RA. These effects were accompanied by a 3.1-fold increase in serum MDA content. The MDA content was higher in RA patients who were seropositive for rheumatoid factor as well as positive for C-reactive proteins. The erythrocyte sedimentation rate for all patients with RA was approximately 13.8-fold higher than for the control group, and was higher among RA patients who were positive for C-reactive proteins and exhibited seropositivity for rheumatoid factor. Patients with RA receiving gold therapy exhibited significantly lower MDA levels whereas all other factors that were measured were not effected. The results support a hypothesis that defense mechanisms against reactive oxygen species are impaired in RA. Copyright © 2001 John Wiley & Sons, Ltd.

TL;DR: In this paper, a cross-sectional, correlational design was adopted to collect data from 365 health-care workers in Amman, Jordan, from August 16th to 23rd, 2020.
Abstract: The emergence of Coronavirus disease 2019 (COVID-19) has affected health-care workers' psychological and mental health. Few studies have been conducted examining the psychological effect of COVID-19 on health-care worker psychological health in Jordan. Therefore, the present study aims to assess the respective levels of fear, anxiety, depression, stress, social support, and the associated factors, experienced by Jordanian health-care workers during the COVID-19 Pandemic. This study adopted a cross-sectional, correlational design to collect data from 365 health-care workers in Amman, Jordan, from August 16th to 23rd, 2020. Along with collecting sociodemographic characteristics, the Fear of COVID-19 Scale, the Depression, Anxiety, Stress Scale, and the Multidimensional Scale of Perceived Social Support electronically administered to participants. The majority of the participants (69.3%) were registered nurses. The mean overall score for the Fear of COVID-19 scale was 23.64 (SD + 6.85) which again exceeded the mid-point for the total score range (21), indicating elevated level fear of the COVID-19 pandemic. Participants had displayed extremely severe depression 40%, extremely severe anxiety 60%, and 35% severely distressed. Scores for depression (21.30 ± 10.86), anxiety (20.37 ± 10.80), stress (23.33 ± 10.87) were also high. Factors determined to be associated with psychological distress were being male, married, aged 40 years and older, and having more clinical experience. Assessment of social support indicated moderate-to-high levels of perceived support for all dimensions (significant other: 5.17 ± 1.28, family: 5.03 ± 1.30, friends: 5.05 ± 1.30). Weak significant correlations were found between social support and the other study variables (r < 0.22), indicating a weak association with fear, depression, anxiety, and stress, respectively. Overall, Jordanian health-care workers sample reported fear, depression, anxiety, and stress. The associated factors were being male, married, aged 40 years and older, and having more clinical experience. Regarding social support, participants primarily relied on support from their families, followed by support from friends.
