The probiotic activity of Lactobacillus acidophilus bacteria as a dietary supplement was estimated by its impact on Nile tilapia's immunological response ( Oreochromis niloticus ) and its protection against challenge infections The present study predestined the effects of different Lactobacillus acidophilus dietary levels as feed supplement on biochemical parameters, antioxidant activity, growth performance and protection of Nile Tilapia against Enterococcus faecalis that previously isolated from cultured Nile Tilapia from Kafr Elsheikh Governorate fish farms that identified by biochemical tests ,API20 E and API20 Strept . Six types of bacteria were isolated: Enterococcus faecalis by 25%, Aeromonas hydrophilla by 20.9%, Pseudomonas.auriginousa by 18.6% S taphylococcus aureus 20.9% . , Escherichia coli by11.6% and Proteus vulgaris by 2.3% were isolated from 60 apparently healthy and naturally infected Nile Tilapia collected from Kafr El Sheikh Governorate fish farms. They were allotted into 5 groups, 1 st and 2 nd group fed on basal diet and 3 rd ,4 th and 5 th fed on basal diet supplemented by different levels of dietary Lactobacillus acidophilus 1.5 × 10 8 , 3 × 10 8 and 6 × 10 8 CFU/g respectively for 10 weeks. Our results reported that the weight gain rate, relative growth rate, feed conversion ratio and average body weight are all improved when varied quantities of L. acidophilus are used as a diet supplement compared to fish fed un supplemented diet. Also showed the superior results in biochemical parameters (significant increase (P < 0.05) in lysosomal activity, bactericidal effect, WBCs, antioxidant enzymes activities and significant decrease (P < 0.05) in cholesterol, cortisol and glucose and the appropriate inclusion is 6 × 10 8 CFU /g. It could be concluded that using Lactobacillus acidophilus is beneficial because it promotes growth, is antimicrobial, and has a positive impact on the gut microbiota. Innate immunity and antioxidant enzymes activities and had hypocholesteremic and hypoglycemic effect. This study highly recommends the use of Lactobacillus acidophilus as biological control promoter in dealing with Enterococcus faecalis infection in fish culture. On our study Lactobacillus acidophilus can boost immunological responses, growth, and fish welfare by acting as a probiotic.
The Influence of Government Shareholding on Dividend Policy in Malaysia

We investigate the association between dividend policy and government shareholding, using Malaysian data. We hypothesize a positive association. We contribute to the literature about dividend policy. Unique features of our study include adaptations to the Malaysian institutional setting, with respect to usage of dividend relevance theory, research methodology, and data collection. The methodology entails two-stage least squares regressions. Dividend payout and dividend yield are the dependent variables in tests of the research hypothesis. The independent variable of interest measures ownership by government-related institutional investors. The sample comprises 1190 company-years, over the investigation period 2006–2013. The results support our hypothesis. The evidence suggests that this support principally emanates from companies with low-quality corporate governance.

Analysis of Hygienic Behavioral Intention on Students of Culinary

The purposes of this study were to analyze the hygienic behavioral intention on students of culinary using theory of planned behavior (TPB) and to analyze the prototype of hygienic behavioral intention on students of culinary during practical work. Respondents of this study were 150 culinary students, either in Diploma 3 or in Bachelor’s degree (S1), at State University of Surabaya. The data of this study was collected by utilizing questionnaire method in order to know the attitude, subjective norm, Perceived Behavioral Control, and the intention to behave hygienic. The collected data was analyzed descriptively and multivariate method. The results of this study showed that intention to behave hygienic on the students was influenced by attitude and perceived behavioral control, which the attitude was influenced by consequence and evaluation, whether, PBC was influenced by power of individual feeling and ability to control his/her behavior. The subjective norm did not have any influence toward the enhancement of the intention to behave hygienic although motivation and normative belief had an influence toward the enhancement of subjective norm. Nevertheless, PBC had the strongest influence to the intention to behave hygienic.
Nanostructure and Luminescent Properties of Bimetallic Lanthanide Eu/Gd, Tb/Gd and Eu/Tb Coordination Polymers

This study presents the synthesis, structural and luminescence properties for lanthanide metal–organic frameworks (LnMOFs), which belong to the sub-class of coordination polymers. The series of nanosized LnMOFs (Ln = Eu, Gd, Tb, Eu0.5Gd0.5, Tb0.5Gd0.5 and Eu0.5Tb0.5) was prepared by solvothermal synthesis using a modulator (sodium acetate). We investigated the various surface chemistry compositions of the isostructural LnMOFs with a [Ln(btc)] structure (BTC: Benzene-1,3,5-tricarboxylate) by X-ray photoelectron spectroscopy (XPS). The XPS confirmed the mixed-valent Eu3+ and Eu2+ compounds, and the presence of Tb in both +3 and +4 valence states, and one +3 valency of Gd. A nanostructure of mixed LnMOFs (EuGd, TbGd and EuTb) with a rod-like shape is related to luminescence properties. The MOFs (EuTb and EuGd) presented Comission Internationale de l’Éclairage (CIE) chromaticities of x = 0.666 and y = 0.331, and x = 0.654 and y = 0.348, respectively, in the red region. They were better than the values desired for use in commercial phosphors, which are x = 0.64 and y = 0.35. For [Tb/Gd(btc)], the CIE coordinates were x = 0.334 and y = 0.562, presenting emissions in the green region. Bimetallic LnMOFs are very promising UV light sensors for biological applications.
The importance of
understanding the connection between the characteristics and motivation of
visitors

The purpose of this paper is to examine the characteristics and motivations of event visitors. The goals are to systematically identify socio-demographic characteristics of visitors to tourist events and identify key motivation for visiting tourist events. In addition, the research aims to investigate the correlation between the socio-demographic characteristics of visitors and their motivations for visiting a tourist event. The research was conducted among the visitors of a tourist event (103 respondents), using the survey method and a pre-designed structured questionnaire. The survey was conducted in April 2017, during the duration of an event which is held every year in the city of Zagreb in the Republic of Croatia. The results of the conducted research have shown significant differences between the different socio-demographic characteristics of the respondents and their motivations. Thus, women are more highly motivated by a desire for cultural experiences (34%), while men are motivated the most by curiosity/desire for new experiences (45%). Furthermore, correlation analysis has led to the conclusion that there is a significant correlation between motivation domains and the socio-demographic characteristics of respondents (gender, age and education). Understanding the visitors’ characteristics and event motivations could serve as a useful tool for event managers. It could help them to develop and manage events, with the aim of improving the event offering to meet the needs and demands of different visitors. Given the growing importance of events as an enrichment element of the tourism offering, this research can contribute to the advancement of knowledge in this field.
A preliminary estimate of how stream water age is influenced by changing runoff sources in the Nagqu river water shed, Qinghai‐Tibet Plateau

Stream water age is an essential indicator of stream water renewal and pollutant transport rates. Recently, the concept of young water fractions, calculated using stable isotopic data, was proposed as a measure of stream water age. However, the current calculation methods do not classify stream water fractions with annual cycles (365 days), which are helpful to understand the sources of runoff and the water renewal rate in the watershed. In this study, we took the Nagqu River Watershed (NRW, with an area of 16 900 km2) as an example and proposed the concept of middle‐aged water to solve this problem. We used two time thresholds τyw and τow to divide the stream water age into young water, middle‐aged water and old water in runoff and calculated middle‐aged water using a distributed hydrological model. The results revealed that in the NRW, an average of 23% of the runoff was less than 51.6 days old, whereas an average of 55% of the runoff had ages ranging from 51.6 to 365 days. The spatial change in stream water age is significantly influenced by the sources of streamflow, evaporation, air temperature and soil moisture. The annual average change in old water storage values were −0.33 km3, suggesting that the mean of old water in the NRW decreased from 2016 to 2019. The results of this study are helpful for the study of sources of streamflow and stream water fractions, as well as providing a more effective understanding of the internal hydrological process in a depopulated alpine zone under the impacts of climate change.
Fractionation of stable carbon isotopes during acetate consumption by methanogenic and sulfidogenic microbial communities in rice paddy soils and lake sediments

Abstract. Acetate is an important intermediate during the degradation of organic matter in anoxic flooded soils and sediments. Acetate is disproportionated to CH4 and CO2 by methanogenic or is oxidized to CO2 by sulfate-reducing microorganisms. These reactions result in carbon isotope fractionation, depending on the microbial species and their particular carbon metabolism. To learn more about the magnitude of the isotopic enrichment factors (ε) involved, acetate conversion to CH4 and CO2 was measured in anoxic paddy soils from Vercelli (Italy) and the International Rice Research Institute (IRRI, the Philippines) and in anoxic lake sediments from the north east (NE) and the south west (SW) basins of Fuchskuhle (Germany). Acetate consumption was measured using samples of paddy soil or lake sediment suspended in water or in phosphate buffer (pH 7.0), both in the absence and presence of sulfate (gypsum), and of methyl fluoride (CH3F), an inhibitor of aceticlastic methanogenesis. Under methanogenic conditions, values of εac for acetate consumption were always in a range of -21 ‰ to -17 ‰, but higher in the lake sediment from the SW basin (-11 ‰). Under sulfidogenic conditions εac values tended to be slightly lower (-26 ‰ to -19 ‰) especially when aceticlastic methanogenesis was inhibited. Again, εac in the lake sediment of the SW basin was higher (-18 ‰ to -14 ‰). Determination of εCH4 from the accumulation of 13C in CH4 resulted in much lower values (-37 ‰ to -27 ‰) than from the depletion of 13C in acetate (-21 ‰ to -17 ‰), especially when acetate degradation was measured in buffer suspensions. The microbial communities were characterized by sequencing the bacterial 16S rRNA genes as well as the methanogenic mcrA and sulfidogenic dsrB genes. The microbial communities were quite different between lake sediments and paddy soils, but were similar in the sediments of the two lake basins and in the soils from Vercelli and IRR, and were similar after preincubation without and with addition of sulfate (gypsum). The different microbial compositions could hardly serve for the prediction of the magnitude of enrichment factors.
Is Mathematics Required for Cooking? An Interdisciplinary Approach to Integrating Computational Thinking in a Culinary and Restaurant Management Course

In recent years, with the flourishing of the catering economy and the trends in computer technology, restaurant operators have increasingly relied on employees with computational and information skills. Breaking through the traditional teaching method of mere lecturing, the study conducts a teaching demonstration by integrating the computational thinking concept and a Microsoft Excel computational system on the school’s E-learning platform into the teaching of a Culinary and Restaurant Management course. A non-equivalent control group pretest–posttest study with a quasi-experimental design is adopted for the assignment of experimental participants and the design of the course. The results show that a curriculum design with computational thinking significantly improves the effectiveness of students’ learning in digital technology and is especially helpful for the cultivation of the key capabilities of menu design and cost planning among restaurant management skills. The study makes the following contributions: during the Culinary and Restaurant Management course, the use of the E-learning platform and computing programs such as Microsoft Excel is associated with greater learning effectiveness than traditional teaching methods. The research results can serve as a reference for promoting an E-catering business model and a sustainable educational model in the future.
Paradoxes of Reactance During the COVID-19 Pandemic: A Social-psychological Perspective

This study aims to explain the dynamics of compliance towards the measures to contain the coronavirus in 2020 by drawing on the theory of psychological reactance. We discuss our findings in a model that distinguishes between catalysts and buffers of reactance arousal on an individual level and hypothesises how these may lead to compliant or resistant behaviour as acts of resilience in the public sphere. In an online survey (N = 766, May 2020, Germany), we found that reactance arousal towards the restrictions to contain the coronavirus depended on the individual assessment of the limitations of freedom. Data suggest that health related fear buffers reactance arousal, whereas surprisingly, sorrow and cognitive dissonance amplify it. Anger and a critical political attitude towards the government correlate positively with the mobilising power of reactance. We argue that these are essential elements that push individual reactance arousal over the threshold into the public sphere, where it serves to shove resilience towards resistance. Our study expands this essential social-psychological theory to be a driver not only in the individual but also in public behaviour, opening a new perspective on the tipping point between resilience and resistance in the public sphere during this crisis and beyond.
BOOST: a phase 3 trial of sorafenib vs. best supportive care in first line treatment of hepatocellular carcinoma in patients with deteriorated liver function

Aim: Only patients with good liver function {[Child-Pugh (CP)] A class} were eligible for trials testing sorafenib as first-line treatment of hepatocellular carcinoma (HCC); nevertheless, the drug was authorized without restrictions based on liver function. Therefore, we planned to test sorafenib efficacy and safety in patients with HCC and deteriorated liver function (CP-B). Methods: This was an open-label, multicenter, randomized phase 3 trial. Patients with HCC, no previous systemic therapy, and CP-B score 7-9 were assigned 1:1 to best supportive care alone (control arm) or with standard dose sorafenib (experimental arm). Overall survival (OS) was the primary endpoint. To detect a 0.70 HR of death, with 80% power, and two-tailed α error 0.05, 234 events were required. The study closed prematurely because of slow accrual. Descriptive analyses are reported. Results: From 2012 to 2017, 13 Italian centers randomized 35 patients. In total, 28 deaths were recorded, 12 without and 16 with sorafenib; median OS was 4.9 (95%CI: 1.2-5.6) and 3.5 months (95%CI: 1.3-5.3), respectively. At least one severe adverse event was reported in 2/15 (13.3%) without and 9/17 (52.9%) patients with sorafenib. Conclusions: This trial failed its planned enrolment goal, showing the difficulty in performing clinical trials with drugs already registered with a label broader than what available evidence supports.
A multi-purpose lifting-line flow solver for arbitrary wind energy concepts

Abstract. In this work, we extend the AeroDyn module of OpenFAST to be able to support arbitrary collections of wings, rotors and towers. The new standalone AeroDyn driver supports arbitrary motions of the lifting-surfaces and complex turbulent inflows. We describe the features and updates necessary for the implementation of the new AeroDyn driver. We present different case studies of the driver to illustrate its application to concepts such as: multi-rotors, kites, or vertical axis wind turbines. We perform verification and validation of some of the new features using the following test cases: an elliptical wing, a horizontal axis wind turbine, and a 2D and 3D vertical axis wind turbines. The wind turbine simulations are compared to field measurements. We use this opportunity to point out some limitations of current models and highlight areas which we think should be the focus of future research in wind turbine aerodynamics.
Celebrity Couples as Business Families: A Social Network Perspective

We depict Hollywood celebrity couples as business families who participate in the project-based movie production industry, which is a temporary and disaggregated form of organization where skilled individuals are linked to one another through contractual and social relationships. Appearing in Hollywood movies generates celebrity capital, which can be converted into economic capital through involvement in endorsements and other rent-generating activities. Finding projects is facilitated by membership in high-quality social networks, and we consider celebrity marriage as a means of merging two individuals’ social networks, which can be mutually beneficial for both parties. We develop and test three hypotheses about the quality of social networks prior to and after marriage and analyze their impact upon celebrities’ postmarriage career performance. We contribute to the family business literature by exploring hybridized and adaptive forms of business family in contemporary project industries, which has the potential to enlarge family business scholars’ research horizons.
Green Growth in the OECD Countries: A Multivariate Analytical Approach

Green growth is about merging environmental and social protection with economic growth. The OECD countries follow the progress toward greening though a set of indicators. The aim of the study is to analyze the condition and development of the OECD countries using a set of green growth indicators. The univariate and multivariate statistical approach was used to identify the main features of green growth development in two time spans. The achieved success of the OECD countries toward the green growth was measured from period 1 (years 2000–2009) to period 2 (years 2010–2019). For stimulant indicators, an increase was achieved, while for the destimulant variables, a decrease was reached between the analyzed periods. CO2 productivity increased by more than 31%, material productivity by 25%, and the energy productivity by nearly 21%. From the ecological point of view, a positive sign was achieved by an intensive increase of the percentage of municipal waste treatment by recycling or composting. The real GDP increased between periods in each of the OECD countries, except in Greece. The destimulant indicators decreased over time. The mortality declined by about 20% from exposure to ambient PM2.5 and thus the welfare costs of premature death from exposure to PM2.5 also declined. The decline of the mean population exposure to PM2.5 by 12.5% on average for the OECD countries is a positive signal for environmental protection and public health of the OECD population. Some uncertainty exists as the municipal waste generated per capita decreased only slightly by 2%.
Properties of Doubly Heavy Baryons

We revisited the mass spectra of the Ξcc++ baryon with positive and negative parity states using Hypercentral Constituent Quark Model Scheme with Coloumb plus screened potential. The ground state of the baryon has been determined by the LHCb experiment, and the anticipated excited state masses of the baryon have been compared with several theoretical methodologies. The transition magnetic moments of all heavy baryons Ξcc++, Ξcc+, Ωcc+, Ξbb0, Ξbb−, Ωbb−, Ξbc+, Ξbc0, Ωbc0 are also calculated and their values are −1.013 μN, 1.048 μN, 0.961 μN, −1.69 μN, 0.73 μN, 0.48 μN, −1.39 μN, 0.94 μN and 0.710 μN, respectively.
Does Adult Day Service Use Improve Well-Being of Black Caregivers of People Living With Dementia?

Abstract Background and Objectives Despite adult day services (ADS) being the most racially diverse home- and community-based service (HCBS), there is a paucity of research that has examined the impact of ADS on well-being measures among Black caregivers of people living with dementia. To address this gap, this study examined the association between the use of ADS and depressive symptoms among Black dementia caregivers. Research Design and Methods Using baseline data from 2 behavioral intervention trials, Advancing Caregiver Training (n = 72) and Care of Persons with Dementia in their Environments (n = 63), we conducted ordinary least squares regression to examine the association between ADS use in the past 6 months and depressive symptoms (n = 135). The dependent variable, depressive symptoms, was assessed by the 10-item Center for Epidemiologic Studies—Depression (CES-D) scale. The independent variable was assessed by self-report of ADS use in the past 6 months. Results Nearly 36% of the sample used ADS in the past 6 months. After controlling for caregiver characteristics associated with depression (burden, social support, self-rated health, caregiving relationship status, years caregiving, religious/spiritual coping, and demographic characteristics), caregivers who utilized ADS had a lowered CES-D score (B = −1.97, p = .03) compared to those who did not use ADS. Discussion and Implications Black dementia caregivers who utilized ADS had lower depressive symptoms compared to those who did not utilize ADS. ADS may be a critical HCBS that can provide relief to Black caregivers. Research is needed to examine additional benefits of ADS use among Black caregivers and the policy and programming needed to enhance access to ADS.
