A growing number of studies on entrepreneurial motivation, intentions, and behavior include entrepreneurial self-efficacy (ESE) as an explanatory variable. While there is broad consensus among researchers on the importance of including ESE in an intentionality model, there remain inconsistencies in the definition, dimensionality, and measurement of ESE. This study takes an important step toward...
Validation And Standardization Of The Questionnaire «Quin – When I Teach» professionalism of a teacher is the topic wide-ranging debate aimed at overcoming crises confidence in this category and reaffirming as valuable source for students’ growth cognitive socio-emotional development. This questionnaire shows validation standardization process self-perception instrument teachers designed to exp...
INTRODUCTION These recommendations are intended to develop a consensus in the previously published papers as to which parameters and what values should be considered critical. A practical guide on the standardization of critical results management in haematology laboratories would be beneficial as part of good laboratory and clinical practice and for use by laboratory-accrediting agencies. ME...
Background. Variable adherence to standardized case definitions, clinical procedures, specimen collection techniques, and laboratory methods has complicated the interpretation of previous multicenter pneumonia etiology studies. To circumvent these problems, a program of clinical standardization was embedded in the Pneumonia Etiology Research for Child Health (PERCH) study. Methods. Between Ma...
An important problem with online data-processing in many analytical laboratories is the connection of different data-ports to analytical instruments. The use of standardized interfaces would go a long way towards solving this problem. This paper gives a status report on the efforts made towards reaching an internationally accepted standard for interfaces which can be used for devices in clinica...
Developing and implementing a set of personal health device interoperability standards is key to cultivating a healthy global industry ecosystem. The standardization organizations, including the Institute of Electrical and Electronics Engineers 11073 Personal Health Device Workgroup (IEEE 11073-PHD WG) and Continua Health Alliance, are striving for this purpose. However, factors like the medial...
Glycated haemoglobin (HbA(1c)) measurements are used in clinical studies and for the management of diabetic patients. Various efforts were made to standardize the HbA(1c) measurements with consensus standards and standards based on a reference measurement procedure with external calibration. According to ISO 17511 a standard should meet highest accuracy possible, have a defined uncertainty of m...
Multicentre patch test studies (MPTSs) can contribute useful information for diagnostic and preventive measures. The aim of the present paper is to propose how to perform high-quality MPTSs. To this end, factors of significance for the patch test result are discussed with regard to the standardization and calibration of high-quality MPTSs. The 16 factors discussed are scored 0, 1, 2, or 3, depe...
A solution containing (68)Ge in equilibrium with its daughter, (68)Ga, has been standardized for the first time at the National Institute of Standards and Technology (NIST) using 3 liquid scintillation-based techniques: live-timed 4πβ -γ anticoincidence (LTAC) counting, the Triple-to-Double Coincidence Ratio (TDCR) method, and (3)H-standard efficiency tracing with the CIEMAT(1)/NIST (CNET) meth...
BACKGROUND α-Klotho is a protein mainly produced in the kidney. Its circulating form has been suggested to link renal damage and distant tissue pathology. As three assays to measure α-Klotho became commercially available, we performed an evaluation of these commercially available Klotho assays. METHODS We studied within-run variation, between-run variation, matrix effects, linearity, and reco...
