METHODOLOGY OF NETWORK ENVIRONMENT TESTING FOR IOT DEVICES

The article describes the basics of testing: writing test documentation (an example based on a report defect was proposed) and some testing methods. A performance test was also developed to test the load. Received basic knowledge of testing theory, as well as skills of writing and using bash scripts for performance tests.

An Agenda for the Study of Public Administration in Developing Countries

Developing nations demand a different scholarly approach in the field of public administration. We advance an agenda for research that stands on four pillars. First, in the absence of easily accessible data scholars of developing world public administration must assemble it for themselves. Second, building and testing theory plays a paramount role because researchers face limited information. Third, in developing countries, multi-national and non-governmental organizations are often crucial and must be considered in studying public administration. Fourth, given the novelties and ambiguities researchers face, qualitative information must be integrated throughout the research process. Our article—and the articles in this volume—constitute a call for developing country research to contribute to the study of public administration writ large, informing our understanding of both developing and developed states.

Accelerated Testing: A Practitioner's Guide to Accelerated and Reliability Testing

The application of accelerated testing theory is a difficult proposition, yet one that can result in considerable time and cost savings, as well as increasing a product's useful life. In Accelerated Testing: A Practitioner's Guide to Accelerated and Reliability Testing, readers are exposed to the latest, most practical knowledge available in this dynamic and important discipline. Authors Bryan Dodson and Harry Schwab draw on their considerable experience in the field to present comprehensive, insightful views in this book. Development and quality assurance tests are defined in detail and are presented from a practical viewpoint. Included are testing fundamentals, plans and models, and equipment and methods most commonly used in accelerated testing. Individuals seeking to evaluate and improve the design lives of components and systems will find this book a valuable reference, with special attention being paid to testing in the mobility industries.

Increasing Participation in Psychological Science by Using Course-Based Research Projects: Testing Theory, Using Open-Science Practices, and Professionally Presenting Research

Introduction: Undergraduate research experiences prepare students for graduate training or employment. Statement of problem: At many teaching-intensive universities, there is a greater demand for research experiences than there are independent study opportunities. Students from typically underrepresented backgrounds may also be unaware of a department’s undergraduate research pipeline of independent study, honor’s theses, and internal research funding. Literature review: Course-based research contributes to diversity and inclusivity in access to undergraduate research experiences, especially at teaching-intensive universities. Course-based research is often integrated into methods courses, but not content courses. Teaching implications: I present practical ways to integrate research projects into courses. I stress the importance of testing theory, teaching open-science practices, and providing opportunities for students to present professionally. I also provide examples of implementing group research projects in content courses. Conclusion: Implementing course-based research projects, especially at teaching-intensive universities, can expand access to psychological science by providing valuable research opportunities for many students. Instructors can also benefit by intertwining their teaching, mentoring, and research goals. Future research should focus on experimentally testing learning outcomes.

Constructing Adaptive Deformation Models for Estimating DEM Error in SBAS-InSAR Based on Hypothesis Testing

The Interferometric Synthetic Aperture Radar (InSAR) technique has been widely used to obtain the ground surface deformation of geohazards (e.g., mining subsidence and landslides). As one of the inherent errors in the interferometric phase, the digital elevation model (DEM) error is usually estimated with the help of an a priori deformation model. However, it is difficult to determine an a priori deformation model that can fit the deformation time series well, leading to possible bias in the estimation of DEM error and the deformation time series. In this paper, we propose a method that can construct an adaptive deformation model, based on a set of predefined functions and the hypothesis testing theory in the framework of the small baseline subset InSAR (SBAS-InSAR) method. Since it is difficult to fit the deformation time series over a long time span by using only one function, the phase time series is first divided into several groups with overlapping regions. In each group, the hypothesis testing theory is employed to adaptively select the optimal deformation model from the predefined functions. The parameters of adaptive deformation models and the DEM error can be modeled with the phase time series and solved by a least square method. Simulations and real data experiments in the Pingchuan mining area, Gaunsu Province, China, demonstrate that, compared to the state-of-the-art deformation modeling strategy (e.g., the linear deformation model and the function group deformation model), the proposed method can significantly improve the accuracy of DEM error estimation and can benefit the estimation of deformation time series.

A Comparative Analysis of the New HSK5 and JLPT1 Based on Language Testing Theory

The purpose of language testing is to better serve language learning and teaching. The ultimate goal is to help learners improve their practical application ability. Therefore, by analyzing HSK’s own knowledge points and knowledge points which are relatively weak compared with JLPT’s, this paper analyzes the key points of daily teaching, goes out of the pattern of simply studying HSK’s exam oriented skills and teaching methods, and discusses its application in daily teaching. In order to improve the teaching method and make the students acquire knowledge step by step. Some skills need solid basic knowledge, but the best reason to pass the exam is to fully understand the content. Therefore, we should try to analyze the content of the examination, and put the key and difficult points of language learning reflected by the examination site into the daily teaching, so as to truly "teach people to fish".

How (Not) To Test Theory With Data: Illustrations from Walasek, Mullet and Stewart (2021)

André and de Langhe (2021) pointed out that Walasek and Stewart (2015) estimated loss aversion on different lotteries in different conditions. Because of this flaw in the experimental design, their results should not be taken as evidence that loss aversion can disappear and reverse, or that decision by sampling is the origin of loss aversion. In their response to André and de Langhe (2021), Walasek, Mullett and Stewart (2021) defend the link between decision by sampling and loss aversion. We take their response as an opportunity to emphasize three guiding principles when testing theory with data: 1) Look for data that are uniquely predicted by the theory, 2) Do not ignore data that contradict the theory, and 3) If an experiment is flawed, fix it. In light of these principles, we do not believe that Walasek, Mullett, and Stewart (2021) provide new insights about the origin and stability of loss aversion.

Scholar to Practitioner

Traditionally, the role of the research supervisor/dissertation chair has been to support the doctoral student with the goal of making the student a scholar through the research conducted for the dissertation. In the traditional research institution environment this research was designed to build theory. Today, while this research tradition still exists and the doctor of philosophy degree continues to be awarded, a shift has occurred in the higher education landscape such that a practice-oriented type of research is being produced in practitioner doctorate programs. Dissertations in the practitioner doctorate should be focused on research that has as its objective solving real world problems. As such, this may be a difficult change for individuals who have been mentoring doctoral students for years with the goal of building or testing theory over application of theory. Seasoned research supervisors/dissertation chairs educated in a research doctorate environment may resist this change, even as they supervise doctoral students studying in a practitioner doctorate environment.
