Methodological Guidelines

ObjectiveThis meta-review aims to discuss the methodological, research and practical applications of tools that assess the measurement properties of instruments evaluating health-related quality of life (HRQoL) that have been reported in systematic reviews.DesignMeta-review.MethodsElectronic search from January 2008 to May 2020 was carried out on PubMed, CINAHL, PsycINFO, SCOPUS, WoS, Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) database, Google Scholar and ProQuest Dissertations and Theses.ResultsA total of 246 systematic reviews were assessed. Concerning the quality of the review process, some methodological shortcomings were found, such as poor compliance with reporting or methodological guidelines. Regarding the procedures to assess the quality of measurement properties, 164 (66.6%) of reviewers applied one tool at least. Tool format and structure differed across standards or scientific traditions (ie, psychology, medicine and economics), but most assess both measurement properties and the usability of instruments. As far as the results and conclusions of systematic reviews are concerned, only 68 (27.5%) linked the intended use of the instrument to specific measurement properties (eg, evaluative use to responsiveness).ConclusionsThe reporting and methodological quality of reviews have increased over time, but there is still room for improvement regarding adherence to guidelines. The COSMIN would be the most widespread and comprehensive tool to assess both the risk of bias of primary studies, and the measurement properties of HRQoL instruments for evaluative purposes. Our analysis of other assessment tools and measurement standards can serve as a starting point for future lines of work on the COSMIN tool, such as considering a more comprehensive evaluation of feasibility, including burden and fairness; expanding its scope for measurement instruments with a different use than evaluative; and improving its assessment of the risk of bias of primary studies.PROSPERO registration numberCRD42017065232.

Sexual Sensation Seeking

Background: STIs, principally HIV/AIDS, are public health problems that are transmitted by sexual risk behaviours, which have been associated with the sexual sensation seeking (an specific personality factor). In South American context, there are no measurement instruments with psychometric evidence for their use and, in other contexts, only the Sexual sensation seeking scale (Kalichman et al., 1994) is available, which is outdated in content and validity evidence. The purpose of this work is development a scale, in accordance with contemporary psychometric standards, to assess sexual sensation seeking for South Americans young people and adults. Method: instrumental study, with time-space sampling (n=813) of undergraduate students from the two Chilean cities with the highest rates of HIV. Results: Final scale have 8 items to assess two dimensions: 1) sexual emotions seeking; and 2) tendency to sexual boredom. The identified structure provides adequate levels of reliability (ω> .8; α> .7), presents validity evidence, based on the internal structure of the test, using CFA and ESEM (CFI> .95, TLI> .95, RMSEA <. 06), and based on the convergence with other measures (sexual activity with multiple partners, inadequate or insufficient use of protective barriers and sexual activity under the influence of alcohol or drugs). Conclusions: The Multidimensional Scale of Sexual Sensation Seeking evidence adequate psychometric properties to evaluate the search for sexual sensations in equivalents samples.

And Performance

Abstract With the ever-increasing density and performance of integrated circuits, non-invasive, accurate, and high spatial and temporal resolution electric signal measurement instruments hold the key to performing successful diagnostics and failure analysis. Sampled electrostatic force microscopy (EFM) has the potential for such applications. It provides a noninvasive approach to measuring high frequency internal integrated circuit signals. Previous EFMs operate using a repetitive single-pulse sampling approach and are inherently subject to the signal-to-noise ratio (SNR) problems when test pattern duty cycle times become large. In this paper we present an innovative technique that uses groups of pulses to improve the SNR of sampled EFM systems. The approach can easily provide more than an order-ofmagnitude improvement to the SNR. The details of the approach are presented.

Б. Ніжинська в Києві у 1919–1921 рр. стала своєрідним транслятором ідей «Російських сезонів» С. Дягілева з їх акцентом на художньому оформленні та оновленні балетної лексики. У діяльності «Школи рухів» Б. Ніжинська змогла розпочати реалізацію власних теоретико-методичних установок щодо нової балетної мови, нового типу танцівника, викладення яких практично завершено саме в Києві. Творчість Б. Ніжинської можна кваліфікувати як опозиційну академічному балету з його усталеними формами. Експерименти в «Школі рухів» та Центростудії стали своєрідною апробацією балетмейстерських прийомів, які згодом реалізовані у «Російському балеті» С. Дягілева та подальшій балетмейстерській творчості, що набула всесвітнього визнання. Ключові слова: Броніслава Ніжинська, «Школа рухів», танцювальна студія, Київ, культурно-мистецьке життя. Nizhinsky in Kiev in 1919–1921 became a kind of translator of the ideas of «Russian Seasons» by S. Diaghilev with their emphasis on the decoration and updating of ballet vocabulary. In the activities of the «School of Movements» B. Nizhinskaya was able to start implementing her own theoretical and methodological guidelines for a new ballet language, a new type of dancer, the exposition of which was practically completed in Kiev. The creativity of B. Nizhinsky can be qualified as opposed to academic ballet with its well-established forms. The experiments at the School of Movements and the Central Studio became a kind of approbation of the choreography techniques, which were subsequently implemented in the Russian Ballet by S. Diaghilev and further choreography, which received worldwide recognition. Key words: Bronislava Nizhinsky, «School of Movements», dance studio, Kiev, cultural and artistic life

Detection Technology

Background: Detection technology is a product development technique that serves as a basis for quality assurance. As electric energy meters (EEMs) are measurement instruments whose use is mandatory in several nations, their accuracy, which directly depends on their reliability and proper functioning, is paramount. In this study, to eliminate electromagnetic interference, a device is developed for testing a set of EEMs under a constant magnetic field interference. The detection device can simultaneously test 6 electric meters; moreover, in the future, it will be able to measure the influence of magnetic field strength on the measurement accuracy of EEMs, thereby improving the production efficiency of electric meter manufacturers. Methods: In this study, we first design a 3D model of the detection device for a single meter component; then, we establish a network, which includes a control system, and perform the planning of the path of a block that generates a constant magnetic field. Finally, we control the three-axis motion and rotation of the block using a PLC to implement detection for the five sides of the EEM. Results & Discussion: The proposed device can accurately determine whether an EEM can adequately function, within the error range prescribed by a national standard, under electromagnetic interference; this can enable reliable, automatic testing and fault detection for EEMs. Experiments show that our device can decrease the labor cost for EEM manufacturers.
