The formulation of diets from vegetable protein enriched with immunostimulants is a suitable feeding strategy for shrimp culture. This study evaluated a feed formulated with wheat (Tritium sativum) and chickpea (Cicer arietinum) enriched with spirulina (Spirulina maxima) for shrimp Litopenaeus vannamei farming. A feed based on wheat and chickpea (2.5:1) containing 3% spirulina was developed and characterized by proximal chemical analysis. The experimental feed was evaluated along with a commercial feed in a five-week field bioassay to determine the growth, survival, and health status of the juvenile shrimp. In addition, water salinity (mg·L-1) was monitored as an environmental stability factor for shrimp cultures. The proximal chemical composition of the experimental feed contained 17.5 ±0.1% protein, 2.2 ±0.3% lipids and 68.0 ±0.3% carbohydrates. The specific growth rate (0.22 ±0.05 g·days-1) of the shrimp under experimental feed did not show statistical differences in comparison with the commercial feed (P> 0.05). Also, it was determined that the shrimp fed with experimental feed presented a biomass production (0.74 ±0.17 g), survival rate (>98%) (P <0.05) and health status better than shrimp fed with commercial feed. The influence of salinity on shrimp survival was rule out (P> 0.05). This study demonstrated that the experimental feed offers a suitable diet in benefit of the performance and health of the shrimp.

Student Worksheet (LKS) is a guide and support for practicum in learning science / science. In biology lessons, especially the material of Spermatophyta Submaterial Plantae, currently it is not optimal. This can be seen from the content of the worksheets that do not cover all the competencies that have been formulated in the curriculum. Therefore, this study aims to reconstruct the worksheets on the Spermatophyta submaterial Plantae. The research method used the ANCOR (Analysis-Try-Reconstruction) approach. At the analysis stage, the LKS analysis process is based on conceptual, practical, and knowledge construction aspects. Then at the trial stage carried out without changes in tools, materials and procedures. Furthermore, the LKS reconstruction refers to the vee diagram and applies a process skills approach. The results showed that there were problems with the Spermatophyta LKS in the field, including the contents of the worksheets that did not cover all the competencies expected by the curriculum, the work steps were less relevant and the discussion questions did not support the student's knowledge construction process. The results of the reconstruction worksheets were added by phenetic analysis activities to align with the basic competencies that had been formulated. These reconstruction worksheets can become alternative worksheets in accordance with curriculum standards and representatives for all time.

Brief Mindfulness Intervention for Emotional Distress, Resilience, and Compassion in Family Physicians During COVID-19: A Pilot Study
Authors: Nutting Ruth , Ofei-Dodoo Samuel , Rose-Borcherding Katherine , Strella Grace 
Published: February 2022

Background and Objective: There are high rates of professional burnout among family physicians and trainees. We undertook this study to investigate whether a brief mindfulness intervention could help manage burnout and improve well-being among family physicians in a residency program.
Methods: A total of 21 family physicians participated in a brief, 8-week mindfulness program. We used a single-sample, pre/post design at a Midwestern family medicine residency program. At two points in time (baseline and postintervention), participants completed an online survey measuring burnout, depression, anxiety, stress, perceived resilience, and compassion. We used linear mixed models to estimate the effect of the intervention on the outcome measures.
Results: Participants had improvements after the 8-week intervention. At postintervention, they had significantly better scores on anxiety (P&lt;.004), stress (P&lt;.001), perceived resilience (P&lt;.001), and compassion (P&lt;.001). There were no significant changes on the personal accomplishment, emotional exhaustion, and depersonalization subscales of either the abbreviated Maslach Burnout Inventory or the depression subscale of the Depression Anxiety Stress Scales-21.
Conclusion: This brief mindfulness program was associated with significant reduction in the scores of anxiety and stress as well as significant improvement in perceived resilience and compassion scores. Brief mindfulness interventions may be a convenient and effective approach to support and improve health and well-being among family physicians.
Why Do Large Positive Non-GAAP Earnings Adjustments Predict Abnormally High CEO Pay?
Authors: Guest Nicholas M. , Kothari S. P. , Pozen Robert C. 
Published: February 2022

ABSTRACT
CEOs of S&P 500 firms that report high non-GAAP earnings relative to GAAP earnings receive substantial unexplained pay. Crucially, this result remains even after controlling for the level of non-GAAP and GAAP earnings. These firms are relatively poor performers (i.e., low GAAP earnings and stock returns) and have less powerful CEOs, consistent with non-GAAP earnings being used as justification when high executive pay is more likely to cause outrage. Additionally, despite the lower GAAP and return performance, these firms are more likely to beat the earnings targets specified in their compensation plans, which likely increases investors' perceptions of core operating earnings and reduces outrage. Indeed, these firms face less dissent from shareholders and proxy advisors, and no additional media scrutiny. Our evidence suggests that the fraction of CEO pay that seems attributable to opportunistic non-GAAP reporting, while limited, is economically meaningful.

Measuring the Information Content of Disclosures: The Role of Return Noise
Authors: Thomas Jacob K. , Zhang Frank , Zhu Wei 
Published: February 2022

ABSTRACT
Disclosure is of fundamental interest to accounting research. When the sign/magnitude of disclosed news is unclear, the information in disclosure events is inferred using the ratio of return volatilities during event and non-event windows (Beaver 1968). We show that return noise due to microstructure frictions and mispricing affects this ratio, and that effect is comparable to or exceeds that of information content. We use the SEC's Tick Size Pilot program to confirm the causal effect of return noise on the ratio, and to evaluate alternative ways to control for it. The most promising approach is to use the difference between, rather than the ratio of, return volatilities during event and non-event windows. We illustrate its benefits by showing how it alters prior inferences regarding time-series and cross-sectional variation in information content as well as changes in the information content of earnings announcements around the 2004 amendments to Form 8-K filings.

Published: February 2022

OBJECTIVE
We sought to evaluate costs associated with public health screening for presymptomatic type 1 diabetes in 90,632 children as part of the Fr1da study in Bavaria and in forecasts for standard care.

RESEARCH DESIGN AND METHODS
We report on resource use and direct costs for screening-related procedures in the Fr1da study coordination center and laboratory and in participating pediatric practices and local diabetes clinics. Data were obtained from Fr1da study documents, an online survey among pediatricians, and interviews and records of Fr1da staff members. Data were analyzed with tree models that mimic procedures during the screening process. Cost estimates are presented as they were observed in the Fr1da study and as they can be expected in standard care for various scenarios.

RESULTS
The costs per child screened in the Fr1da study were €28.17 (95% CI 19.96; 39.63) and the costs per child diagnosed with presymptomatic type 1 diabetes were €9,117 (6,460; 12,827). Assuming a prevalence of presymptomatic type 1 diabetes of 0.31%, as in the Fr1da study, the estimated costs in standard care in Germany would be €21.73 (16.76; 28.19) per screened child and €7,035 (5,426; 9,124) per diagnosed child. Of the projected screening costs, €12.25 would be the costs in the medical practice, €9.34 for coordination and laboratory, and €0.14 for local diabetes clinics.

CONCLUSIONS
This study provides information for the planning and implementation of screening tests for presymptomatic type 1 diabetes in the general public and for the analysis of the cost-effectiveness of targeted prevention strategies.

Published: February 2022

The author believes that the absolutizaton of liberal democracy and human rights when they are not subject to critical analysis, as well as the start of transformation of the USA from republic to empire, and the democracy – to the manipulative power of the elite, which were perhaps inherent to the very nature of American models of republic and democracy, put forward the problem of the return of irrationalism into mass consciousness and politics. In the context of this problem the author analyzes Western political philosophy and theology for the last few years, paying special attention to theological grounds for the appearance of liberalism.
Impacts of Environmental Variations on Quality and Chemical Contents of Oriental Tobacco
Authors: Kurt Dursun 
Published: February 2022

Summary
Basma tobaccos, in addition to Izmir and Samsun type tobaccos, are the most important high-quality oriental tobacco types grown in Turkey. This research was carried out to determine the effects of a variety of environmental conditions, in four locations on different altitudes on the yield as well as on nicotine, sugar and phenolic substances content. The plant material of the study included 21 Basma lines, which were selected according to their morphological differences and from genotypes separated by DNA fingerprint analysis, and four standard cultivars/lines (checks). The quality grade index of the genotypes was determined by the American grading method and chemical analyses were carried out using a high-performance liquid chromatography (HPLC) system. All the parameters investigated indicated that genotypes were significantly affected by the variation in environmental conditions. Organoleptic observations showed that the quality grade index of genotypes ranged from 24.17 to 100%, and the ERB-7, ERB-13, ERB-15, ERB-19 and ERB-38 lines had the best quality. Nicotine contents of tobacco lines were between 0.31 and 3.15% dry matter (DM). Glucose, fructose and their sum (reducing sugar) contents of genotypes ranged from 1.16 to 8.88% DM, from 2.60 to 8.66% DM and from 4.44 to 15.03% DM, respectively. The ERB-21 and ERB-30 lines are noteworthy tobacco types in terms of reducing sugar contents. The values of chlorogenic acid, one of the phenolic compounds, ranged from 40.67 to 1119.76 ppm, the values of rutin from 121.05 to 1021.53 ppm, and the sum of these two phenolic compounds was from 174.94 ppm to 2019.41 ppm. The effect of variations in the environment on the quality of Oriental tobacco can be clearly explained by the variations in the parameters.
