Abstract

This book provides an overview of the research related to psychological assessment across South Africa. The thirty-six chapters provide a combination of psychometric theory and practical assessment applications in order to combine the currently disparate research that has been conducted locally in this field. Existing South African texts on psychological assessment are predominantly academic textbooks that explain psychometric theory and provide brief descriptions of a few testing instruments. Psychological Assessment in South Africa provides in-depth coverage of a range of areas within the broad field of psychological assessment, including research conducted with various psychological instruments. The chapters critically interrogate the current Eurocentric and Western cultural hegemonic practices that dominate the field of psychological assessment. The book therefore has the potential to function both as an academic text for graduate students, as well as a specialist resource for professionals, including psychologists, psychometrists, remedial teachers and human resource practitioners.&#xD;

Abstract

Evaluations of intervention programs seek to present high-quality design, measures and data to assess their merit and worth. While evaluations differ in their purpose, theoretical framework and methodology, their collective aim is to obtain relevant and meaningful information to inform practice, research, and policy. As such, evaluation findings serve to build a body of knowledge on effective approaches to promote designated psychological outcomes, critical to an individual's overall health and well-being. However, as examined in this e-book, methodological weaknesses directly limit the potential of evaluations of intervention programs. As discussed by Chacón-Moscoso and Sanduvete-Chaves, methodological weaknesses can be attributed to how to define and measure methodological quality and the contextual dependency of instruments designed to measure this quality.In response, this e-book provides a collection of studies on methodological approaches to promote the quality of psychological interventions. Specifically, 10 original works published in the Research Topic Methodological Quality of Interventions in Psychology are included. The papers are organized into two chapters. Concretely, Chapter 1 includes studies pertaining to methodological approaches to enhance the quality of psychological intervention, being context independent solutions. Furthermore, Chapter 2 presents original work in different areas (health, education, sport and social welfare) where methodological quality has been better assessed. Collectively, the papers in this e-book serve to expand the awareness of practitioners and researchers interested in psychological interventions of the critical role of methodological quality in this work. This research was funded by the projects 1150096 (Chilean National Fund of Scientific and Technological Development, FONDECYT); and PSI2015-71947-REDT (Spain’s Ministry of Economy and Competitiveness).

Abstract

This chapter presents the fate of the charge carriers from the moment of its photogeneration in the perovskite to injection and transport into electrodes. Time-resolved electrical measurement techniques, terahertz (THz) spectroscopy and microwave (MW) conductivity, are primarily used to deconvolute ultrafast processes and to directly access behavior of charged species from the ps to µs timescales. Transient absorption and photoluminescence spectroscopy were also utilized to gain insight on carrier population dynamics and radiatively recombining charges. Photogenerated charged species were converted into highly mobile charges (µe = 12.5 cm2V-1s-1 and µh = 7.5 cm2V-1s-1) almost instantaneously (< 0.2 ps), while the remaining loosely bounded excitons dissociate into mobile charges after 2-3 ps. This high mobility is maintained for at least 1 ns as obtained by THz spectroscopy, while its lifetime is at least few tens of µs as measured by the MW conductivity technique. Lowering the temperature increases carrier mobilities with T-1.6.Dependence and a 75 meV barrier energy is required for temperature-activated recombination. Finally, injection of hole from MAPbI3 to Spiro-OMeTAD was found to be ultrafast and the state and population of dark holes dictate its recombination.

Abstract

In 2003, Rachel A. Volberg wrote: “Why is it that gambling is not even on the radar when we consider the array of risks that adolescents must confront as they move towards adulthood?” Nowadays, after thirteen years, although much more is known about this particular form of risk behavior, there is still a general tendency, at least among laypersons, to not perceive gambling as a potential danger for youth and other population segments (e.g., individuals with migration background, seniors, sports professionals). However, the latest edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5, American Psychological Association, 2013) included Gambling Disorder as the only condition in the Section Non-Substance-Related Disorders. Moreover, it is specified that the disorder can indeed occur in adolescence or young adulthood. Despite this fact, theoretical and applied research on problem gambling with regard to adolescence and other risk groups is still in its infancy.For this reason, it seems to be important to organize a Research Topic on gambling in Frontiers in Psychology in order to i) highlight the necessity of considering gambling as a potential harmful activity; ii) summarize the state-of-art of international research on different aspects of the topic; and iii) offer important novel findings relevant for advancing knowledge in the field of gambling. Different types of research articles will be provided including original articles, systematic/scoping reviews, meta-analyses, case reports, and commentaries. These contributions will be focused on the following most important areas in gambling research: Measurement (Which are the most widely used instruments to assess gambling-related problems as well as proximate constructs and what are their psychometric properties? Are there new instruments to detect adolescent problem gamblers?), Protective and risk factors (What do we know about ecological and individual influences on gambling behavior? Which factors affect problem gambling most and in which way?), Prevention (Which are the most promising prevention programs implemented until now? Which are necessary ingredients for effective prevention?), Treatment (When individuals seek help for their gambling-related problems, which are the clinical treatments that are offered? Do we have evidence for treatment effectiveness for different subgroups?).To try to fulfill this goal in the most comprehensive way, researchers from different countries and with specific competencies and interests will be contacted and encouraged to submit a contribution. Through the integration of international and multidisciplinary contributions, i) new challenges in the field of gambling will be identified (e.g., definition of specific at-risk groups, specification of effective interventions in terms of best practices) and ii) new research routes (e.g., the use of behavioral data) will be outlined in order to build a comprehensive understanding of problem gambling. The overall aim is to summarize the state of art, to propose original novel findings, and to outline new directions in gambling research.

Abstract

Process measurement deals with the quantification of business process models using process model metrics. This book presents a theoretical framework for the prediction of external process model attributes (as, for example, error-proneness and understandabiltiy) based on internal (structural) attributes. The properties of proposed metrics are analyzed. A visualization technique for metric values is introduced and metrics for process model understandability and granularity are evaluated.

Abstract

Although the world has seen a strong increase in global incomes in the last two decades and consequently a decline in global poverty rates, the number of persons living in absolute poverty remains on unacceptably high levels. Besides rising incomes can not distract from the fact that resources to fight global problems remain scarce. These resources have to be devoted to the fight against different global problems like the fight against communicable and non-communicable diseases (especially HIV/AIDS and Malaria) or the fight against global warming. The main precondition to achieve the best results with these limited resources is a good knowledge about the determinants and the best policies to fight each problem. But before being able to analyze the determinants of the different global problems and especially of poverty, it is of fundamental importance to find the right indicators for each phenomenon. This book contributes to the discussion of appropriate poverty indicators for the different dimensions of poverty like income poverty, undernutrition and child mortality and proposes a multidimensional poverty indicator that takes the income distribution into consideration.

Abstract

Mathematical anxiety is a feeling of tension, apprehension or fear which arises when a person is faced with mathematical content. The negative consequences of mathematical anxiety are well-documented. Students with high levels of mathematical anxiety might underperform in important test situations, they tend to hold negative attitudes towards mathematics, and they are likely to opt out of elective mathematics courses, which also affects their career opportunities. Although at the university level many students do not continue to study mathematics, social science students are confronted with the fact that their disciplines involve learning about statistics - another potential source of anxiety for students who are uncomfortable with dealing with numerical content. Research on mathematical anxiety is a truly interdisciplinary field with contributions from educational, developmental, cognitive, social and neuroscience researchers. The current collection of papers demonstrates the diversity of the field, offering both new empirical contributions and reviews of existing studies. The contributors also outline future directions for this line of research.

Abstract

Die Ausgestaltung von Performance Measurement orientiert sich an branchenspezifischen Charakteristika. Mit Hilfe eines Mixed-Methods-Ansatzes zeigt die Autorin für den Einzelhandel, welche Erfolgskennzahlen relevant sind. Der Fokus liegt auf der Verwendung von Performance-Kennzahlen auf der Filialebene. Die Ausgangsbasis der Analyse bildet ein Literaturüberblick, der die kennzahlenorientierte Handelsmarketingforschung der letzten 50 Jahre beleuchtet. Problemzentrierte Leitfadeninterviews mit Handelsmanagern aus dem US-amerikanischen und deutschsprachigen Raum zeigen Unterschiede im Verständnis der Konzeption. Eine Face-to-Face-Befragung von Managern sowie ein conjoint-analytischer Ansatz präsentieren Relevanz und Nützlichkeit von Handelskennzahlen im Alltag.
