We study spectral features of Alfvénic turbulence in fast solar wind. We propose a general, instrument independent method to estimate the uncertainty in velocity fluctuations obtained by in-situ satellite observations in the solar wind. We show that when the measurement uncertainties of the velocity fluctuations are taken into account the less energetic Elsasser spectrum obeys a unique power law scaling throughout the inertial range as prevailing theories of magnetohydrodynamic turbulence predict.

With the development of measuring technology,the measuring accuracy of optical glass refractive index of the increasingly high demand,V prism refractometers is major general instrument for measuring the refractive index of optical glass,not only the simple device,convenient measurement,and this method has high precision performance,however,the accuracy is only attained ,which in the regulation of national metrology verification and the introduction of V prism refractometers in the literature,the classic formula calculation principle formula error caused by refractive index has more than .Based on the mechanical structure and optical transmission to improve the original V prism refractometers the refractive index of air,by considering the influence on measurement precision of V prism refractometer,to mathematical modeling of V prism refractometer the principle formula,V can be measured refractive prism refractometer rate accuracy increased to ,measurement repeatability less than ,has important practical significance for realizing high accuracy measurement of the refractive index of optical glass.

Introduction: Insufficient physical activity is one of the leading public health problems in the world, but also in Bosnia and Herzegovina. Modern civilization is characterized by a significant decrease in physical activity, and the number of people whose lifestyle can be called sedentary has never been higher, which is especially emphasised among children and adolescents. Aim of the study is to examine public health significance of physical activity on the occurrence and the degree of obesity in children and adolescents in primary and secondary schools and to determine the applicability of the Fels questionnaire on physical activity of children in rural areas of Bosnia and Herzegovina. Methods: We used a transversal research method of a cross-sectional study at a one-time point, and for obtaining results we used the Fels physical activity questionnaire for children and measurement protocol. Results: 276 primary and secondary school students in two cities participated in this survey. Respondents in Busovača are more physically active than their peers in Sarajevo. One-third of the total number of respondents is overweight and obese, and respondents in Sarajevo are significantly more nourished than their peers in Busovača. The Fels questionnaire is conditionally applicable, especially in rural areas. Conclusion: This study confirmed that the Fels questionnaire for assessing the level of physical activity for children and young people, which is the general instrument for research of physical activity in children, is too generalized because it is based on a homogeneous urban population.

ABSTRACT Objective: To develop and validate an instrument for the self-assessment of the Patient Safety Centers in health care institutions. Method: Non-experimental methodological study. Divided in the following stages: literature review and construction of the preliminary instrument; content validation by nine professionals with experience in Quality Management and patient safety, who contributed to the adequacy of the items in terms of clarity and relevance; finally, 12 PSC coordinators, which conducted the reliability validation of the final instrument, using Cronbach's Alpha. Results: The instrument presented content validity regarding clarity and relevance, evidenced by an agreement level greater than 70%. The internal consistency presented high reliability, with a Cronbach's alpha of 0.857 for the general instrument, 0.825 for the domain Structure, and 0.809 for the domain Process. Conclusion: The instrument presented evidence of content validity and reliability for self-assessment, implementation and evaluation of the PSC in health institutions.

AbstractThe Reference Intensity Ratio (RIR) is a general, instrument-independent constant for use in quantitative phase analysis by the X-ray powder diffraction internal standard method. When the reference standard is corundum, RIR is known as I/Ic; These constants are collected in the Powder Diffraction File (1987), can be calculated, and can be measured. Recommended methods for accurate measurement of RIR constants are presented, and methods of using these constants for quantitative analysis are discussed. The numerous, complex constants in Copeland and Bragg's method introduced to account for superimposed lines can be simply expressed in terms of RIR constants and relative intensities. This formalism also permits introduction of constraints and supplemental equations based on elemental analysis.

Purpose: This research aims to get an individual work performance scale of the modified version which is more acceptable and has a good psychometric property.  Methodology: This study was conducted using a modified measuring instrument approach. Researchers use existing theories and then make items according to the context in which this research will be conducted. The advantage of this modification approach is getting a more comprehensive understanding of the subject we are researching. Main Findings: Of the 303 employees that were tested in the research, the modification scale of the individual work performance has a good psychometric property with the criteria of reliability more than 0.8 and the fit model that has a good item with RMSEA score (0.062). Other than that, the modification scale of individual work performance shows a good convergent validity with presenteeism and correlate with job burnout. Applications of this study: The Individual Work Performance Scale has a comprehensive methodology and good psychometric properties. This instrument is appropriate to be the general instrument for seeing the employee situation. In addition, this instrument can also be used as a set of tests that are suitable for use by those who will conduct an assessment of employee performance. Novelty: This scale was made as a form of development from previous research which did not explore and develop forms of assessment that were specific to an employee's performance. There is not much-related research that focuses on many dimensions that are actually important to assess in employee performance.

Purpose The importance of co-innovation platforms has been well established, but a valid and reliable instrument to measure the affordances of these platforms for co-innovation behavior has not yet been reported in the literature. A robust, validated instrument to measure co-innovation platform affordances (PAs) will facilitate the conduct of studies across different platforms and contribute to enhanced understanding of co-innovation behaviors, outcomes, and platform design. The purpose of this paper is to conceptualize co-innovation PAs, develop a reliable measurement instrument capturing critical facets of co-innovation, namely ideation, collaboration, and communication, and validate the instrument. Design/methodology/approach The construct of PAs was conceptualized based on the findings from two case studies of co-innovation networks and the key characteristics of social mediating technology affordances. The measurement items newly developed via a case study underwent a two-round exploratory analysis to ensure face validity and content validity. The resulting instrument was subjected to a pilot study and a field study to establish the necessary reliability and validity. Findings The findings of the study reveal that co-innovation PAs have three distinctive components, namely ideation, collaboration, and communication. Furthermore, the results of the study suggest that PAs are most appropriately operationalized as a second-order construct comprising all three components. The empirical results from the field study show a high degree of confidence in both translation validity and criterion-related validity. Originality/value Drawing from co-innovation and affordances literature, this study develops and validates a general instrument to measure co-innovation PAs. The result is a reliable and parsimonious instrument with 12 items. The authors believe that the instrument can contribute significantly to future empirical investigations of co-innovation behavior on virtual platforms.
