The Effect of Managerial Ability on the Association Between CEO Tenure and Downward Pay Rigidity

This paper explores the phenomenon of downward pay rigidity by employing a regime-switching model that distinguishes between rigid and flexible regimes in U.S. companies during the 1993-2013 period. Downward pay rigidity refers to the asymmetric patterns that reflect positive pay-performance sensitivity when firms perform well, but less positive sensitivity when performance worsens. Depending on managerial power theory, we postulate that downward pay rigidity intensifies with CEO tenure. In addition, we investigate the effects of managerial ability on downward pay rigidity in relation to the effect of CEO tenure. The results suggest that CEO compensation is downwardly rigid for long-tenured CEOs. However, the results of the null hypothesis testing the incremental impact of CEO managerial ability on the association between CEO tenure and downward rigidity shows that talented CEOs with longer tenures are less likely to experience downward pay rigidity. The findings imply that long tenure of CEOs enables them to extract greater levels of rents. However, the incremental effect of CEO ability is consistent with the confidence hypothesis, suggesting that talented CEOs with long tenure are less likely to seek opportunities to extract rents than their less-talented counterparts.
A theory-based electronic learning intervention to support appropriate antibiotic prescribing by nurse and pharmacist independent prescribers: an acceptability and feasibility study.

Objectives: To assess the acceptability and feasibility of using a theory-based electronic learning intervention designed to support appropriate antibiotic prescribing by nurse and pharmacist independent prescribers for patients presenting with common, acute, uncomplicated self-limiting respiratory tract infections (RTIs). Design: Experimental with mixed methods; pre- and post-intervention online surveys and semi-structured interviews. Setting: Primary care settings across the United Kingdom. Participants: 11 nurse and 4 pharmacist prescribers. Intervention: A theory-based brief interactive animation electronic learning activity comprised of a consultation scenario by a prescriber with an adult presenting with a common, acute, uncomplicated self-limiting RTI. Outcome measures: Recruitment, response and attrition rates were assessed. Overall usefulness of the intervention was assessed by analysing prescribers’ self-reported confidence and knowledge in treating patients with RTIs before and after undertaking the intervention, and views on the relevance of the intervention to their work. Acceptability of the intervention was assessed in semi-structured interviews. The feasibility of data collection methods was assessed by recording the number of study components completed by prescribers. Results: 15 prescribers (maximum sample size) consented and completed all four stages of the study. Prescribers reported high to very high levels of confidence and knowledge pre- and post-intervention, with slight post-intervention increases in communicating with patients and a slight reduction in building rapport. Qualitative findings supported quantitative findings; prescribers were reassured of their own practice which in turn increased their confidence and knowledge in consultations. The information in the intervention was not new to prescribers but was applicable and useful to consolidate learning and enable self-reflection. Completing the e-learning intervention was acceptable to prescribers. Conclusions: It was feasible to conduct the study. The intervention was acceptable and useful to prescribers. Future work will review the clinical content in the intervention before conducting a full trial.
A Simple Home-Based Lifestyle Intervention Program to Improve Cardiac Autonomic Regulation in Patients with Increased Cardiometabolic Risk

Lifestyle modification programs (LMP) represent a new approach to cardiometabolic/oncologic risk reduction. Successful LMP in clinical practice must be feasible, cost effective, efficacious and consider home-based exercise. Likewise, multiple mechanisms implied in cardiometabolic risk reduction such as cardiac autonomic regulation (CAR) should be easily evidenced, in spite of the computational complexity involved. This goal could be facilitated by employing novel, friendlier, simpler techniques, such as the Autonomic Nervous System Index (ANSI), which can be treated as a proxy of CAR. In this observational study, we introduce a simple LMP (based on cognitive behavioral strategies and patient-tailored prescription of nutrition and home-based exercise, managed by a single physician) into the currently existing clinical practice of secondary cardiometabolic prevention. In 26 subjects, we assessed CAR (autoregressive spectral analysis of cardiovascular variabilities), body mass composition (bioelectrical impedance analysis) and stress perception (questionnaires). After LMP, ANSI and lipid profile were improved; % of fat mass, waist circumference and stress perception were reduced. We conclude that this preliminary, proof of concept study provides significant evidence in favor of the hypothesis that it is possible to introduce a convenient, cost effective LMP into the currently existing clinical practice of secondary cardiometabolic prevention. Findings suggest a successful comprehensive behavioral change, possibly facilitated by the simplified approach employed in this study, capable of improving cardiac autonomic regulation in addition to body mass composition and stress perception.
MULTICULTURAL LEADERSHIP AND THE ROLE OF THAI SCHOOL LEADERS

: Today’s globalized world has the direct impact on groups of people with a variety of ethnic groups, genders, and talents and so on which is known as multiculturalism. The educational design is required to meet the needs for changing the educational environment in more holistic ways so as to reach the achievement of the equality of education. Many interesting findings have been derived from much of multicultural education research in Thailand, especially in educational management. Thai school leaders are required to have multicultural leadership and play the crucial roles with the aim to effectively respond to diversity and as a result the achievement of the equality of education for all groups of people in the Thai society.
Effects of Organic Mulch Materials on Soil Surface Evaporation

The effects of organic mulching material on soil surface evaporation were studied in Abia State. The objective of the study was to compare impact of mulch materials on saturated hydraulic conductivity and surface evaporation. The organic mulch materials were composted and non-composted Calapogonuim, Chromolena and Panicum spp. The design was randomized complete block design (RCBD). Data generated were statistically analysed. Analysis of variance was used to compare the influence of mulch materials on the measured soil properties and significant means were separated using least significant differences at 5% level of probability. Line graph was used to represent the impact of mulch materials on the surface evaporation. Results showed that saturated hydraulic conductivity of the soils increased significantly (P ≤ 0.05) with the application of the mulch materials. Soil applied with non-composted Chromolena spp. mulch material had the highest saturated hydraulic conductivity (73.00 cm hr-1). Soil surface evaporation varied with both composted and non-composted mulch materials at 3rd and 9th day. The volume of soil moisture lost to the atmosphere was lower in non-composted Calapogonuim mulch material compared with the other mulch materials under study (3rd to 9th day, 3.9 to 11.0 cm3 respectively). Composted and non-composted Panicum mulch was observed to be a more efficient physical barrier to prevent the loss of moisture to the atmosphere as compared to other mulch materials studied. From the present study, it was evident that application of mulch reduced the actual evaporation rates in the initial days after irrigation (coinciding with early periods of plant growth). The water was thus conserved and could be used by the crop subsequently during the later period of its growth.
In Vitro Antioxidant Activity of Hydrophila auriculata Leaves Extract and Silver Nanoparticles

Antioxidant activity of Hydrophila auriculata leaf extract and silver nanoparticles (AgNPs) were carried out for proving its utility in free radical mediated diseases. The flower extract and silver nanoparticles were screened for in vitro antioxidant activity by oxygen radical scavenging such as DPPH, total antioxidant assay and superoxide radical scavenging activity at different concentrations. The antioxidant potential was found to be dose dependent. AgNPs possess probable antioxidant activity as compared with Hydrophila auriculata leaf extract and near to the standard. It is an obvious indication that the resulting activity of the AgNPs is not due to any capping agents, which are found in minute amounts but is due to the elemental silver.
Low serum 25-hydroxyvitamin D levels, tooth loss, and the prevalence of severe periodontitis in Koreans aged 50 years and older

Purpose Vitamin D deficiency may cause bone loss and increased inflammation, which are well-known symptoms of periodontal disease. This study investigated whether serum 25-hydroxyvitamin D (25(OH)D) levels are associated with periodontal disease status and tooth loss. Methods Cross-sectional data from 5,405 individuals aged ≥50 years (2,253 males and 3,152 females) were obtained from the 2008–2010 Dong-gu study, a prospective cohort study of risk factors for chronic diseases. Periodontal examinations were conducted to evaluate the number of remaining teeth, the periodontal probing depth (PPD), the clinical attachment level (CAL), and bleeding on probing. The percentages of sites with PPD ≥4 mm and CAL ≥4 mm were recorded for each participant. The severity of periodontitis was classified using the Centers for Disease Control and Prevention and the American Academy of Periodontology case definitions. Serum 25(OH)D levels were classified as reflecting severe deficiency, deficiency, insufficiency, or sufficiency. Multivariate linear regression analysis was performed to assess the associations of serum 25(OH)D levels with periodontal parameters and the number of remaining teeth after adjusting for confounders including age, smoking status, alcohol consumption status, month of blood collection, and physical activity. Multivariate logistic regression was used to evaluate the association between serum vitamin D levels and severe periodontitis. An overall statistical analysis and a stratified analysis by sex were performed. Results Overall, the rates of severe deficiency, deficiency, insufficiency, and sufficiency were 6.5%, 67.9%, 22.4%, and 3.2%, respectively. After adjustment for confounders, vitamin D levels were directly associated with the number of remaining teeth, an association that was significant in males, but not in females. Sufficient serum 25(OH)D was associated with a low frequency of severe periodontitis. Conclusions This population-based cross-sectional study indicates that low serum 25(OH)D is significantly associated with tooth loss and severe periodontitis in Koreans aged 50 years and older.
Speciation of Pu(VI) in Near-Neutral Solutions via Laser Photoacoustic Spectroscopy

The high sensitivity technique of laser photoacoustic spectroscopy and visible absorption spectroscopy were utilized to investigate the hydrolysis of Pu(VI) in perchlorate media. Pu(VI) absorption bands in the 600 to 700 nm were characterized as a function of pH in the pH = 1-7 regime. The formation constant of the 1:1 hydrolysis complex was determined as {beta}{sub 11} = 5.2 based on observed changes in the absorption bands noted. In the pH region investigated, four distinct species were identified and evidence for the existence of polynuclear species was obtained. 13 refs., 12 figs., 2 tabs.
The response of durum wheat varieties from semi-arid environment to drought stress on germination and at the seedling stage.

Abdel-Ghani, A. H. , Al-Dalain, S. A. , Thaher, N. H. , Owais, S. J., Sarayrh, S. I. , Mayta, R. & Duwayri, M. A. (2020). The response of durum wheat varieties from semi-arid environment to drought stress on germination and at the seedling stage. Bulg. J. Agric. Sci., 26 (2), 299–308 Early drought is a major constraint for cultivating wheat crop in the semi-arid region resulted in poor emergence and weak seedlings and might lead to a complete crop failure under severe drought. The response of eight wheat varieties to simulated osmotic stress was assessed using 10% and 15% polyethylene glycol (PEG-6000), in addition to the control treatment (no stress). Water stress during germination had no effect on the final germination percentages, but it delayed germination with significant differences among genotypes. Results showed that severe osmotic stress (15% PEG) substantially delayed germination; however, mild osmotic stress (10% PEG) had a little effect on germination rate. Furthermore, the results of this study showed that the fastest germinating varieties regardless of osmotic stress level were Acsad 65, Cham I and Ammon. Assessment of coleoptiles and seminal roots demonstrated that HoraniNawawi and Omqais varieties had the longest coleoptiles while Acsad 65 and BaniSuef 6 had the longest seminal roots. The pattern of response of wheat genotypes to osmotic water stress showed substantial differences at the early stage of plant development. Genotypes with a fast germination and a more vigorous root system are very desirable for the rapid establishment of seedlings and their early vigor in the dry areas.

Contemporary Challenges in Entrepreneurial Marketing: Development of a New Pedagogy Model

Entrepreneurial marketing (EM) in SMEs is greatly different than the traditional marketing in large organizations. The higher education institutions generally instruct traditional marketing through orthodox and conventional teaching pedagogies. In consequence, the literature highlights the graduate entrepreneurs struggling in EM during the start-up phases of their small and medium sized entrepreneurial ventures, which is also causing many of them to fail and unable to contribute to the economy. To address this contemporary problem, the current study has used multiple case studies and triangulated its findings with a focus group discussion. The study has explored the EM challenges during the start-up phase faced by the graduate entrepreneurs who have exposure to both, higher education and practical EM experiences. After the rigorous analysis, four contemporary EM challenges due to the pedagogical gaps in entrepreneurship education are discovered. To overcome these challenges, a practical model of EM pedagogy has been developed that is grounded in, the recent entrepreneurship education literature; and the recommendations from the graduate entrepreneurs as well. The EM pedagogy model is practically implementable at business schools worldwide to produce high quality graduate entrepreneurs in the future, which are well-skilled to overcome EM challenges and survive.
Potential Changes in Watermelon (Citrullus lannatus) Ploidy Treated By Colchicine

The purpose of this study was to determine the effect of colchicine on changes in ploidy watermelon. The research was conducted in Agroecotechnology laboratory Universitas Malikussaleh, Microtechnique laboratory Agronomy and Horticulture Departement, Bogor Agricultural University, and Beuringen, Murah Mulia subdistrict, North Aceh. This research used Completely Randomized Design (CRD) two factors. The first factor was watermelon seed soaking time in colchicines 0,02% ie.0, 24,36, and 48 hours. The second factor was the concentration of the colchicine solution on the sprout growth point i.e. 0, 0,1, and 0,2 %. The results showed that plants were given colchicine became to shorter and fewer number of leaves than plants without any treatment. Colchicine could increase the size of the stomata, but it did not change the shape of stomata. Plants that were given colchicine had the potential to ploidy multiplication.
Experimental and Numerical Study of Laminar-Turbulent Transition on a Low-Pressure Turbine Outlet Guide Vane

This work presents an experimental and numerical investigation of the laminar-turbulent transition and secondary flow structures in a turbine rear structure (TRS). The study was executed at engine representative Reynolds number and inlet conditions at three different turbine load cases. Experiments were performed in an annular rotating rig with a shrouded low-pressure turbine upstream of the TRS test section. The numerical results were obtained using the shear stress transport k − ω turbulence model and the Langtry–Menter γ − θ transition model. The boundary layer transition location at the entire vane suction side is investigated. The location of the onset and the transition length are measured using IR-thermography along the entire vane span. The IR-thermography approach was validated using hot-wire boundary layer measurements. Both experiments and computational fluid dynamics (CFD) show large variations of transition location along the vane span with strong influences from endwalls and turbine outlet conditions. Both agree well with traditional transition onset correlations near midspan and show that the transition onset Reynolds number is independent of the acceleration parameter. However, CFD tends to predict an early transition onset in the midspan vane region and a late transition is present in the hub region. Furthermore, in the hub region, CFD is shown to overpredict the transverse flow and related losses.
Execution and perception of older adults fallers and nonfallers performing dual task: cross-sectional study

Objective : To describe and compare the execution time and perception of older adults difficulty performing dual-task paradigm. Methods : This study is a cross-sectional. We included 30 older adults individuals aged 60 years or older of both sexes, 12 of whom were fallers and 18 were nonfallers. We excluded older adults with scores less than or equal to 22 on the Leganés Cognitive Test and severe mobility limitations that corresponded to scores lower than 4 on the Functional Ambulation Category scale. The evaluations were performed in a reserved room, in the afternoon shift of a single day, with an average duration of 50 minutes, by a trained examiner. Results : There was an increase in the execution time of the tests with a dual task condition, except for Time Up And Go test with a motor task when completed by the group of older adults fallers. Conclusions: The addition of motor and cognitive tasks to gait increased the execution time of the tests.
Comparing Trimetazidine with Allopurinol in Prevention of Contrast Induced Nephropathy After Coronary Angiography

Objectives Contrast-induced nephropathy is considered a serious complication following coronary angiography increasing morbidity and mortality. Various drugs have been assessed to reduce the incidence of contrast-induced nephropathy. In this study, we compared trimetazidine and allopurinol as a pharmacological measure to reduce the incidence of contrast-induced nephropathy. Methods One hundred and twenty patients undergoing coronary angiography with baseline creatinine clearance more than 30 ml/minute were divided into three groups, 40 patients each. Group 1 received standard parenteral intravenous hydration in the form of isotonic saline at a rate of 1 ml/kg body weight per hour started 12 hours before angiography and up to 12 hours after the procedure. Group 2 received trimetazidine 35 mg twice per day for 72 hours starting 48 hours before the procedure in addition to intravenous hydration. Group 3 received allopurinol 300 mg once daily for 72 hours starting 48 hours before the procedure in addition to intravenous hydration. Serum creatinine and creatinine clearance were measured before and 72 hours after the procedure in addition to the volume of contrast media used. Results Trimetazidine and allopurinol failed to reduce contrast-induced nephropathy significantly. Among patients with contrast-induced nephropathy volume of contrast media was significantly higher. Conclusion Adding trimetazidine or allopurinol in addition to regular intravenous hydration with isotonic saline without targeting selectively high-risk patients did not reduce contrast-induced nephropathy following coronary angiography
Significant role of wild Genotypes of tomato trichomes for Tuta absoluta resistance

Tuta absoluta is a devastating pest of tomato. The use of host plant resistance to control pests is an interesting, potentially useful technique, but there is no known cultivated tomato resistant to T. absoluta. The objective of this resistance was to screen wild tomato accession and identify resistance mechanism against T. absoluta. Sixteen wild tomato accessions from six species were tested in two experiments. The tested parameters were damaged leaf area, oviposition rate, emerged larvae, adult and larvae survival, larvae and adult preference. Those parameters were correlated with the density of each trichome type and with LC-MS data. From no-choice test parameters accession LA1777, LA1718 and LA716 were the most resistant and LA1401 and LA1139 were the most susceptible, and all S. lycopersicum accessions were susceptible. From choice test, the accessions G1.1561, LA1718, LA716, LA1645, LA0483 and LA1408 were not preferred by the larvae, and the accessions LA1777 and G1.1561 were the least preferred by the adults. The accession LA1777 and LA716 were out of the most resistance. The resistance of this genotype was related to the presence of trichome Type I and IV.
