Development and Content Validity of the Physical Activity Questionnaire-Young Children (PAQ-YC) to Assess Physical Activity in Children between 5 and 7 Years

Childhood is a critical period in the development and consolidation of healthy habits, such as the practice of physical activity (PA). It is essential to have valid instruments to measure PA from an early age. The aim of this study was to design and evaluate the content validity of the Physical Activity Questionnaire-Young Children (PAQ-YC) to measure the PA level in children aged 5–7 years. The first version of the questionnaire was tested by a 2-round Delphi study. It was established as a consensus criterion that the relative interquartile range (RIR) and/or the coefficient of variation (CV) were ≤20%. The most significant discrepancies in the Delphi survey (n = 11–13) were observed for items about hours of Physical Education or similar activities at school (item 7: RIR = 20, CV = 38.73) and for items about participation in Physical Education (item 8: RIR = 25, CV = 15.45). The cognitive interviews (n = 5) confirmed the version agreed by the experts. The results show that the PAQ-YC presents adequate content validity in terms of relevance, comprehensiveness and comprehensibility.

Retrospection of Anti–Blood Group Antibody Proficiency Testing Data Using the Geometric Mean and Standard Deviation

Objectives We reanalyzed the data from proficiency testing (PT) to assess the effect of the geometric mean in the statistical analysis of immunohematologic data. Methods Using the five most recent anti–blood group antibody titer participant summary results, the geometric mean (GM) ±2 × geometric standard deviation (GSD) was used as the comparative consensus criterion to mode ±2 titers. Results Using the PT evaluation criterion of mode ±2 titers, the mean percentages of participants with acceptable results were 97.5% and 97.8% for anti-A and anti-D, respectively. When applying GM ±2 GSD, the mean percentages of acceptable results were 96.1% (anti-A) and 96.1% (anti-D). The percentages of responses included in each consensus criterion were lower using GM ±2 GSD, with a few exceptions. Conclusions Geometric means are more robust and precise in visualizing the central tendency. This method can improve the statistical robustness of PT evaluations.

Robust Protocol-Based ℋ∞ Consensus Control of Time-Varying Uncertain Multiagent Systems Subject to Missing Measurements

In this paper, we consider the design problem of a robust ℋ∞ consensus controller for discrete time-varying uncertain multiagent systems (DTVUMASs) with stochastic communication protocol (SCP) and missing measurements. The SCP is described by a set of random variables with a known probability to arrange signal transmission of addressed multiagent systems. Moreover, we depict the missing measurement phenomenon by a sequence of Bernoulli-distributed random variables having known probabilities. The controller parameters are designed to ensure that the closed-loop DTVUMASs satisfy the ℋ∞ performance with the satisfactory consensus criterion. Together with the completing squares approach and the stochastic analysis methodology, some sufficient conditions are proposed by solving coupled backward recursive Riccati difference equations (BRRDEs) to guarantee the ℋ∞ consensus performance. Finally, we present a numerical simulation example to illustrate the effectiveness of the designed controller design scheme.

PENENTUAN BOBOT KEPENTINGAN DECISION MAKER DALAM GROUP DECISION MAKING

Generally, there are two criteria which are widely used to determineDM’s weight of interest, i.e. competenceand consensus. Various studies related to determine DM’s weight of interest based on competence or consensusseparately have been conducted. Each criterion has its own advantages. The advantage of using competence as acriterion is DMs who have high competence based on their consistence on the decisions made will have high of interest weight. Meanwhile, consensus criterion emphasizes a DM/s contribution to a group without consideringthe DM’s ability or competence.Considering the advantages of both criteria, this study developed a model to determine DM’s weight of interestby considering the DM’ competence and consensus in a GDM. This study used2 group decision making cases totaling in 6 groups consisting of 5 people each. Collected data was then processedusing DM’s weight of interest determination method based on competence and consensus. A model was thendesigned using regression method and fuzzy method. Therefore, a model to determine DM’s weight of interest was obtained by considering competence and consensus. DM’s weight of interest from each method was then involvedin group decision making. The research result showed that group decisions made by involving DM’s weight of interest were better decisions. It implies competence and consensus are two criteria which can be used to determineDM’s weight of interest.

Consensus of Nonlinear Complex Systems with Edge Betweenness Centrality Measure under Time-Varying Sampled-Data Protocol

This paper proposes a new consensus criterion for nonlinear complex systems with edge betweenness centrality measure. By construction of a suitable Lyapunov-Krasovskii functional, the consensus criterion for such systems is established in terms of linear matrix inequalities (LMIs) which can be easily solved by various effective optimization algorithms. One numerical example is given to illustrate the effectiveness of the proposed methods.

Professional competencies in primary health care for attending to older adults

Objective To identify and analyze the necessary competencies in primary health care for attending to older adults. Method An exploratory, descriptive, and quali-quantitative study was developed. Three rounds of the Delphi Technique were conducted with participants from primary health care services and a multidisciplinary committee. The first questionnaire asked participants to indicate the competencies needed for attending to older adults in primary health care. They were compiled into a list and added to a Likert Scale (from 1 to 5) for the second and third questionnaires. A consensus criterion of 70% was adopted. Results Twenty eight competencies were reached by consensus and were classified into twelve domains. Conclusion The competencies reflect Brazilian health care policy and constitute a reference for professional health practice and education when caring for the older adult in primary health care.

Consensusabilization for Continuous-Time High-Order Multiagent Systems with Time-Varying Delays

For the consensus problems of high-order linear multiagent systems with time-varying delays in directed topologies, the LMI based-consensus criterion and NLMI-based consensusabilization (protocol parameters design that makes the multiagent systems achieve consensus) are investigated. Improved Lyapunov-Krasovskii functional is used for establishing the consensus convergence criteria and deriving the corresponding consensus protocol. In order to reduce the conservativeness, some proper free-weighting matrices are added into the derivative of Lyapunov-Krasovskii functional and that only keeps one necessary zoom. The numerical and simulation examples are given to demonstrate the effectiveness of the theoretical results. Compared with existing literatures, the convergence criterion and protocol design proposed have lower conservativeness.
