Cognitive diagnostic test design (CDTD) has a direct impact on the pattern match ratio (PMR) of the classification of examinees. It is more helpful to know the quality of a test during the stage of the test design than after the examination is taken. The theoretical construct validity (TCV) is an index of the test quality that can be calculated without testing, and the relationship between the PMR and the TCV will be revealed. The TCV captures the three aspects of the appeal of the test design as follows: (1) the TCV is a measure of test construct validity, and this index will navigate the processes of item construction and test design toward achieving the goal of measuring the intended objectives, (2) it is the upper bound of the PMR of the knowledge states of examinees, so it can predict the PMR, and (3) it can detect the defects of test design, revise the test in time, improve the efficiency of test design, and save the cost of test design. Furthermore, the TCV is related to the distribution of knowledge states and item categories and has nothing to do with the number of items.

The Relationship

Studies evaluating the cost and quality of healthcare services have produced inconsistent results. We seek to determine if higher paid hospitals have higher quality outcomes compared to those receiving lower payments, after accounting for clinical and market level factors. Using inpatient commercial claims from the IBM® MarketScan® Research Databases, we used an ordinal logistic regression to analyze the association between hospital median payments for elective hip and knee procedures and 3 quality outcomes: prolonged length of stay, complication rate, and 30-day readmission rate. Patient-level and market factor covariates were appropriately adjusted. Hospital-level payments were found to be not significantly correlated with hospital quality of care. This research suggests that higher payments cannot predict higher quality outcomes. This finding has implications for provider-payer negotiations, value-based insurance designs, strategies to increase high-value care provision, and consumer choices in an increasingly consumer-oriented healthcare landscape.

Fatigue is a common and highly distressing symptom of cancer associated with reduced quality of life and considerable psychological and functional morbidity. The reported prevalence of cancer-related fatigue ranges from 4% to 91%, depending on the specific cancer population studied and the methods of assessment. Cancer-related fatigue has typically been underreported, underdiagnosed, and undertreated. Fatigue and depression may coexist in cancer patients, and considerable overlap of symptoms occurs. This is partly the reason for the interest in examining the role of psychotropic medications in treating fatigue. Clarifying the relationship between depression and fatigue is necessary to effectively evaluate and treat cancer-related fatigue. Even with International Classification of Diseases criteria, differentiating cancer-related fatigue is difficult. Psychotropic drugs that have been studied for cancer-related fatigue include psychostimulants, wakefulness-promoting agents, and anti-depressants. Methylphenidate has been studied most and seems to be effective and well tolerated despite common side effects. Some preliminary data support using modafinil in cancer-related fatigue with less concern about tolerance or dependence. Antidepressant studies have shown mixed results. Paroxetine seems to show benefit for fatigue primarily when it is a symptom of clinical depression. Bupropion, a norepinephrine/dopamine reuptake inhibitor, may have psychostimulant-like effects, and therefore may be more beneficial for treating fatigue. However, studies are currently limited. Randomized, placebo-controlled trials with specific agents are needed to further assess the efficacy and tolerability of psychotropic medications in the treatment of cancer-related fatigue.

Introduction. The article is devoted to a current issue of improving the quality of road surface cleaning and increasing the resource of brush working equipment. Improving the quality of cleaning and the resource of the brush working equipment will reduce the cost of operating a communal machine. In the process of operation, the pile of the cylindrical brush is worns out, while its elastic characteristics change, which is reflected in the required pressing force to maintain the most favorable value of the width of the contact spot from the condition of ensuring high quality cleaning and minimal intensity of pile wear.Materials and methods. The results of studies of the interaction of the pile of a cylindrical brush with the surface to be cleaned are presented at various degrees of wear of the brush pile. The research results are presented in analytical and graphical forms. The calculations were carried out using the Microsoft Excel software product and the Mathkad software environment for mathematical calculations.Results. The paper shows the dependence of the degree of wear of the pile of the brush working equipment on the actual radius of the cylindrical brush. The relationship between the width of the contact spot and the deformation of the cylindrical brush at different degrees of wear and tear is shown as a graph.The influence of the degree of wear on the elastic characteristics of the brush working equipment is considered. The dependences of the average stiffness coefficient on the degree of wear of the pile of a cylindrical brush, as well as the required pressing force on the degree of wear at different values of the width of the contact patch of the cylindrical brush are given.

Abstract Objectives: To evaluate disease activity status using the Acromegaly Disease Activity Tool (ACRODAT®) in a cohort of Spanish acromegaly patients, to assess the relationship between the level of disease activity according to both ACRODAT® and the physicians’ clinical evaluation, and to study the potential discrepancies in the perception of symptoms between physicians and patients.Design: Multicenter, observational, descriptive and cross-sectional study. Methods: Disease activity was assessed in adult patients with acromegaly under pharmacological treatment during at least 6 months using ACRODAT®.Results: According to ACRODAT®, 48.2%, 31.8% and 20.0% of a total of 111 patients were classified as having a stable disease (S), mild disease activity (M-DA) and significant disease activity (S-DA) respectively. ACRODAT® classification of disease activity significantly correlated with physicians’ opinion, with a moderate inter-rater agreement and a specificity of 92.45% (PPV=86.21%). No correlation was found between IGF-1 levels and severity of symptoms or quality of life (QoL). A decision to take clinical action was significantly more frequent in S-DA and M-DA patients than S patients but no action was taken on 5 (22.7%) and 27 (77.1%) S-DA and M-DA patients, respectivelyConclusions: ACRODAT® detected disease activity in 51.8% of patients. Interestingly, although M-DA and S-DA patients were likely to be in the process of being controlled, action was not always taken on these patients. ACRODAT® is a validated and highly specific tool that may be useful to routinely monitor acromegaly and to identify patients with non-obvious disease activity by incorporating “patient-centered” parameters like symptoms and QoL to the clinical evaluation of acromegaly.

With the development of the market and market relations such goods as flowers, planting material and others are increasingly encashed in the market of Ukraine and become the objects of forensic merchandising examinations and expert researches. Special feature of merchandising researches of the plant origin objects is the use of the comprehensive approach to the estimation of their quality and cost. Researches are carried out with the purpose of determination of properties, consumer value, conformity to standards and specifications of plants certain kinds. When studying a considerable variety of flower plants, one distinguishes scientific and industrial classifications. In merchandising flowers industrial classification of flower ornamental plants which provides distribution of flower plants to the separate groups similar on biological properties, the agricultural technician of cultivation and practical application in gardening is used. During carrying out merchandising examinations on an establishment of consumer properties of certain kinds plants, namely establishments organoleptic indicators of quality and quantity of flower decorative production given for research, the expert checks conformity of this production to requirements of normative and technical documents. Requirements to quality of flower production are normalised by standards depending on production kind – cutf lowers, pottery blossoming plants, pottery decorative sheet plants, sprouts of flower decorative production, planting material, seeds of flower ornamental plants. At carrying out merchandising researches of flower decorative production, plants and saplings it’s necessary for merchandising experts to pay special attention on definition of quality indicators and a grade of plants according to standards, and also to consider data concerning age of a plant, novelty of a grade and origin country of production.

the main issue of the study is the problem of improving the efficiency of the housing sector. The current state system does not ensure the proper efficiency of the housing stock, which is increasingly manifested in the growing gap between the cost of operation of apartment buildings, aimed at ensuring the quality of their functioning and the real state of this quality. In recent years, numerous regulatory documents have been adopted to ensure the normal maintenance of buildings, but a comprehensive understanding of the relationship of various activities with technical and economic solutions, in most cases, has an empirical nature, not confirmed by a strict analytical justification. The purpose of the study is a systematic integrated approach to solving problems to improve the efficiency of maintenance of housing using the proposed mathematical apparatus, which allows you to objectively, fully and accurately assess the relationship of economic and technical indicators. All total socially significant economic indicators of operational measures can be the basis of legislative regulation in the industry. Conclusions: criteria for assessing the effective and safe operation of buildings, optimal for residents of apartment buildings and management companies serving these houses.

<p>When planning a geochemical survey, it is necessary to make decisions about the sampling density. Sampling density determines both the quality of predictions and the cost of field work. In geostatistical surveys, the relationship between sampling density and map quality, as measured by the kriging variance (mean square error of the prediction) can be computed. When the variogram is known, then the kriging variance at an unsampled site depends only on the spatial distribution of sampling points around that site. It is therefore possible to find the sample density such that the kriging variance is limited to acceptable values. However, the implications of kriging variances are not always straightforward for decision makers or sponsors of survey to understand. Here we present an alternative method to help end-users assess the implications of uncertainty in spatial prediction in so far as this is controlled by sampling.  It is called the offset correlation and is a measure of how far the mapped spatial variation depends on the positioning of a reqular square sampling grid.  The offset correlation increases as the uncertainty in the map, attributable to sample density, decreases.  It is bounded on the interval [0,1], which makes it intuitively easy to interpret as an uncertainty measure.  In this presentation we shall explain the offset correlation concept, illustrate it with some test cases, and provide session participants with an opportunity to join an elicitation of sampling density for a hypothetical survey of soil micronutrient status.</p><p>The offset correlation is an intuitive measure of the precision of a geostatistical mapping process because people can more easily grasp bounded measures like a correlation than unbounded ones like a variance.</p>

The study aimed to identify the relationship between talent management and enhancing the competitive advantage of some sports federations in the Egyptian and Bahraini societies, in addition to the difference in this according to the variables of both experience and level of employment. To achieve this, the researchers used both Talent Management and Competitive Advantage quetionair as a tool to collect data and information from a sampling sample of (50) and a core sample of (247) board members and employees of Egyptian and Bahraini sports federations. The results of the study showed that there is no relationship between the methods of managing human talent between the Egyptian and Bahrain sports federations. There is a positive relationship in the quality of talent in the Bahraini unions and creativity in the Egyptian and Bahraini federations. The results also indicate that there is no difference between the Bahraini and Egyptian federations in the management of sports talents and the promotion of competitive advantage due to the variables of experience and level of employment. Researchers have recommended that specific criteria be used to attract sports talent and retain competencies to reduce the cost of spending on sports talent.
