Measurement Issues in the Application of Screening Tools for PTSD.

Psychometrics is a term within the statistical literature that encompasses the development and evaluation of psychological tests and measures, an area of increasing importance within applied psychology specifically and behavioral sciences. Confusion continues to exist regarding the fundamental tenets of psychometric evaluation and application of the appropriate statistical tests and procedures. The purpose of this paper is to highlight the main psychometric elements which need to be considered in both the development and evaluation of an instrument or tool used within the context of posttraumatic stress disorder (PTSD). The psychometric profile of a tool should also be considered in established tools used in screening PTSD. A “standard” for the application and reporting of psychometric data and approaches is emphasized, the goal of which is to ensure that the key psychometric parameters are considered in relation to the selection and use of PTSD screening tools.

The development of entrepreneurial culture in a transition economy: an empirical model discussion.

This conceptual paper will focus on the presentation of the model developed from empirical, qualitative research covering 20 years of analysis on the relationship between culture and entrepreneurship in Poland. It is aimed at proposing a comprehensive framework that describes the development of entrepreneurial culture. In this empirical model culture is understood as a set of values and beliefs held by a social group that endorse and are conducive to entrepreneurial behaviour; while entrepreneurial behaviour is treated as an expected outcome and narrowed down to opening the company. The model proves that the differentiation between entrepreneurship (behaviour) and entrepreneurs (who demonstrate this behaviour) needs to be recognised in future research. The case of Poland offers a historical example, which can shed more light on the process of cultural change and the role of entrepreneurship and entrepreneurs in the development of entrepreneurial culture. In the case presented, the behaviour of entrepreneurs has been identified as the key factor leading to further development.

Solar photovoltaic system applications: a guidebook for off-grid electrification.

Presenting a complete guide for the planning, design and implementation of solar PV systems for off-grid applications, this book features analysis based on the authors’ own laboratory testing as well as their in the field experiences. Incorporating the latest developments in smart-digital and control technologies into the design criteria of the PV system, this book will also focus on how to integrate newer smart design approaches and techniques for improving the efficiency, reliability and flexibility of the entire system. The design and implementation of India’s first-of its-kind Smart Mini-Grid system (SMG) at TERI premises, which involves the integration of multiple renewable energy resources (including solar PV) through smart controllers for managing the load intelligently and effectively is presented as a key case study. Maximizing reader insights into the performance of different components of solar PV systems under different operating conditions, the book will be of interest to graduate students, researchers, PV designers, planners, and practitioners working in the area of solar PV design, implementation and assessment.
