Background: The joint interest of clinicians and the laboratory test industry during the recent pandemic of the Coronavirus Disease 2019 (COVID-19) resulted in an explosion of accessible assays for COVID-19 serological testing. Content: The need of properly evaluated laboratory tests is more apparent today than ever before. Clinical application of the assay, analytical specifications, and performance convenience are the key criteria that must be followed while selecting an analytical method. An analytical evaluation is always performed before deciding to apply a procedure in the laboratory routine practice. Summary: Only after the evaluation, data collection, and analysis of the results in accordance with the established eligibility criteria can be concluded that the new assay is suitable for laboratory use.

In this paper, the authors present the results of research on the use of software tools for data collection and analysis in strategic and current library management. Special attention has been paid to StatuS and Performance Analysis for Polish Research Libraries (AFBN) — the tools most frequently used by Polish academic librarians. StatuS is used by the academic libraries of Krakow Library Group and several other libraries in Poland. Performance Analysis of Polish Research Libraries (AFBN) is a national project. Its main objective is to create standards for Polish libraries based on a set of performance indicators. AFBN consists of the e-survey, a database and special software for the collection and analysis of data. The surveys are submitted by academic and public research libraries once a year. The research on the application of selected software tools for data collection and analysis in library management in Polish academic libraries was conducted in February and March 2009. Results of the research reflect attitudes of managers toward usability of such tools to support various aspects of managerial processes.

Background Increasing access to Advanced Placement (AP) coursework has been a long-term goal of the College Board and many districts across the country, yet achieving this goal has remained elusive, particularly for African American and Latinx youth and youth in poverty. Purpose In this study, we analyze the work of five districts that have identified inequities in AP participation and developed initiatives to address these inequities. We examine these districts’ strategies, as well as their impact on both access to AP coursework and success on AP exams. We consider how efforts to increase access to AP have affected different racial/ethnic student groups. Participants The five districts are led by superintendents who were members of the Instructional Leaders Network (ILN), a statewide network that focuses on supporting superintendents’ system-wide, equity-focused improvement. The districts vary in demographics, size, and socioeconomic status. Data Collection and Analysis This mixed methods study includes five years of AP enrollment and performance data for four districts, and two years of data for one district. We also identified two of these districts as case studies of AP initiative development and implementation and conducted a series of interviews with administrators from the districts over the five years of the study. We analyzed quantitative data descriptively and used Bonilla-Silva's (2018) concept of color-blind racism to analyze these data in relation to the interview data. Findings All districts adopted strategies focused on students as a whole, which for the most part led to an increase in access for all racial/ethnic groups, but no consistent pattern of reducing over- or under-representation. In terms of outcomes, in some districts, more students received scores of 3 or higher from all racial/ethnic groups, but disparities in average test scores remained. Additionally, across all districts, Black students continued to receive the lowest scores. Conclusions As school districts, individual high schools, and the College Board continue their focus on increasing equity in both access and performance, their approaches need to involve ongoing data collection and evaluation on how different programs and initiatives are positively or negatively affecting student populations that have been traditionally under-served as well as students in general. This research demonstrates that color-neutral policies need to be constantly interrogated by K–12 administrators and other stakeholders to ensure that the policies do not reinforce and sustain existing inequities. If districts seek to target groups of students who are underserved, they need to consider strategies and policies that explicitly and directly address those groups.

The photoluminescence of carbon quantum dots synthesized from natural honey and mixtures of honey and sugar has been studied. An increase in the sugar content leads to a decrease in the photoluminescence intensity without changing the shape of the luminescence spectrum of these quantum dots aqueous solutions, which is associated with a decrease in the yield of their synthesis in the sugar presence. The discovered effect can be used to detect sugar in honey. When examining five different market samples of flower honey using this method, two of them showed a significant decrease in the photoluminescence intensity. A laboratory test for compliance with GOST 19792-2017 Standard requirements established an excess of the sucrose content in these samples. Luminescent determination of sugar in honey does not require complicated equipment and can be used to develop a new analytical method for determining the sugar content in counterfeit natural honey.

The purpose of this study are: 1) To clarify whether there is influence organizational culture, leadership and organizational climate on employee performance Bhayangkara Padang Hospital and 2) Measure the influence of organizational culture, leadership and organizational climate on employee performance Bhayangkara Padang Hospital. Based on test validity workplace culture, leadership, work climate and performance in mind all the items declared invalid meet the eligibility criteria are good and reliable instrument. Work Culture regression analysis obtained by value t = 2.091 while t table = 1.988, so t count> t table and the significance value is 0,040 this value is smaller than α = 0.05 not significant effect on employee performance Padang Police Hospitals. Leadership regression analysis obtained by value t = 1.762 while t table = 1.988 so that t
