The analysis of penalty kick has played an important role in performance analysis. The study aims are to get formal feedback on the relevance of variables for penalty kick analysis, to design and validate an observational system; and to assess experts’ opinion on the optimum video footage in penalty kick analysis. A structured development process was adopted for content validity, reliability and agreement on video usage. All observational variables included in OSPAF showed Aiken’s V values above the cut-off (for 5-scale V> 0.64; for 2-scale = V > 0.75; p < 0.05). Cohen’s Kappa resulted in mean intra- and inter-rater reliability values of 0.90 and 0.86, respectively. It is recommended to combine at least three different viewing angles (V = 0.90; p = 0.006) with standardization of video quality (V = 0.95; p = 0.006). Changing the viewing angles may influence the observer perception (V = 0.86; p = 0.006). The aerial and pitch-level viewing angle behind the penalty taker and pitch-level viewing angle behind the goalkeeper were indicated as most appropriate for observational analysis (V = 0.97; p = 0.01). The OSPAF met all requirements of instrument validation. It may be recommended as basis of future observational systems on penalty kicks.

Face Validation

This article presents the validity bias review feedback and outcomes of new performance-based assessments to evaluate candidates seeking principal licensure. Until now, there has been little empirical work on performance assessment for principal licensure. One state recently developed a multi-task performance assessment for leaders and has implemented it for statewide use in initial principal licensure decisions; this development process is described here, focusing on content validity and bias review, and incorporates candidate and program faculty validiation as well. The results demonstrate the content validity, relevance, and feasibility of this new performance assessment for leaders, and yield implications for leader assessment generally.

Efl Learning

A context where learning a language takes place may be one of many factors influencing the result of the learning. So far, there has been very few, if not at all, a ready-to-use instrument to examine systematically the condition of learning contexts, especially related to English as a foreign language. Therefore, this study intends to develop a self-reported questionnaire for that purpose, named the EFL Learning Context Questionnaire (ELCQ). The instrument was developed in reference to the existing theories and previous related studies. The development process started with writing the draft of the questionnaire in English and then translating into Indonesian language. The next stage would be validation the instrument, including: expert judgement for content validity and to gather constructive feedbacks (i.e. revisions and suggestions), initial piloting for analysing item validity and reliability (N = 64), and final piloting using Factor Analysis to obtain a stable self-reported instrument (N = 692). The validation result showed that the QELC has been proved to be a valid and reliable questionnaire. Since the ELCQ has been validated through some formal stages, it can be assumed that this instrument can be used in EFL contexts, especially in Indonesia. However, because this study took place in only one region, further studies across samples, time and countries are needed to improve the applicability of the ELCQ.

In most industrial embedded systems development projects, the software and the hardware development parts are separated, and the constraint requirements/capabilities are informally exchanged in the system development phase of the process. To prevent failures due to the violation of timing constraints, hardware components of the platform are typically over dimensioned for the capabilities needed. This increases both cost and power consumption. Performance analysis is not done sufficiently at early stages of the development process to optimize the system. This chapter presents results of the integration of tools and extra modeling to offer new performance analysis capabilities in the early stages of the development process. These results are based on trace generation from code instrumentation. A number of enhancements were made, spanning the system modeling stage down to the execution stage (based on an ARM dual core Cortex A9-based target board). Final results taken from a software-based radio case study (including the analysis and validation stages) are presented.
