Introduction to Interpersonal Acceptance-Rejection Theory (IPARTheory) and Evidence

Interpersonal acceptance-rejection theory (IPARTheory) is an evidence-based theory of socialization and lifespan development. It is composed of three subtheories, each of which deals with a separate but interrelated set of issues. IPARTheory’s personality subtheory – which is the most highly developed component of the theory – deals primarily with the pancultural nature and effects of interpersonal acceptance and rejection. Coping subtheory explores the fact that some individuals are better able to cope with experiences of perceived rejection than are other individuals. Finally, IPARTheory’s sociocultural systems subtheory attempts to predict and explain major causes and sociocultural correlates of interpersonal acceptance-rejection worldwide. Empirical evidence overwhelmingly supports the theory’s major postulates and predictions, especially postulates and predictions in personality subtheory. Emerging evidence about the neurobiological and biochemical risks posed for the development, structure, and function of the human brain are beginning to help explain why these postulates and predictions are so consistently confirmed panculturally

Policy and the K–12 music teacher: a literature review

Music teaching lies at the intersection of policy, research, and practice. An awareness of policy context and how policies affect teachers is essential for those in the music education profession. In particular, such an understanding can allow teachers to better adapt to and implement policies so that they might maintain and grow their programs and feel more satisfied in their jobs. This review of literature investigates scholarly literature published in music education research journals with implications for teachers’ classroom practice and their professional lives. It includes studies of resources, organizations, and educational reform, teachers and teaching, institutions and actors, and access, in addition to descriptions of policy. Implications for teachers related to policy awareness, access for all students to a variety of musical activities, and music education advocacy are discussed.Accepted manuscrip

Becoming music teachers: preservice music teachers' early beliefs about music teaching and learning

A major component in the socialisation of teachers is the development of a belief system, which is closely related to their identities. A better understanding of the belief systems and identities of preservice teachers when they begin the process of secondary socialisation could influence approaches to teacher preparation. The purpose of this study was to understand preservice teachers’ initial beliefs about music education as well as their conceptualisations of their identities. Data were drawn from selected assignments completed by students who were enrolled in an introductory-level music education course at a university in the northeastern United States. Through an analysis of the data using a constant comparative approach, three broad themes emerged: A desire to share and develop passion; expressing, feeling, and emotional growth; and providing opportunities for all students. Implications for teacher educators and suggestions for further research are discussed.Accepted manuscrip

Applications and Interviews. A Structural Analysis of Two-Sided Simultaneous Search

Much of the job search literature assumes bilateral meetings between workers and firms. This ignores the frictions that arise when meetings are actually multilateral. I analyze the magnitude of these frictions by presenting an equilibrium job search model with an endogenous number of contacts. Workers contact firms by applying to vacancies, whereas firms contact applicants by interviewing them. Sending applications and interviewing applicants are costly activities but increase the probability to match. In equilibrium, contract dispersion arises and workers spread their applications over the different contract types. Estimation of the model on the Employment Opportunities Pilot Projects data set provides values for the cost of an application, the cost of an interview, and the value of non-market time. Frictions on the worker and the firm side are estimated to each cause approximately half of the 4.7% output loss compared to a Walrasian world. I show that in the estimated equilibrium welfare is improved if unemployed workers increase their search intensity.Directed Search, Recruitment, Stable Matching, Labor Market Frictions, Structural Estimation, Efficiency, Policy Analysis

Applications and Interviews: A Structural Analysis of Two-Sided Simultaneous Search

A large part of the literature on frictional matching in the labor market assumes bilateral meetings between workers and firms. This ignores the frictions that arise when workers and firms meet in a multilateral way and cannot coordinate their application and hiring decisions. I analyze the magnitude of these frictions. For this purpose, I present an equilibrium search model of the labor market with an endogenous number of contacts between workers and firms. Workers contact firms by applying to vacancies, whereas firms contact applicants by interviewing them. Sending more applications and interviewing more applicants are both costly activities but increase the probability to match. In equilibrium, contract dispersion arises endogenously and workers spread their applications over the different types of contracts. Estimation of the model on the Employment Opportunities Pilot Projects data set provides values for the fundamental parameters of the model, including the cost of an application, the cost of an interview, and the value of non-market time. These estimates are used to determine the loss in social surplus compared to a Walrasian world. Frictions on the worker and the firm side each cause approximately half of the 4.7% loss. There is a potential role for activating labor market policies, because I show that for the estimated parameter values welfare is improved if unemployed workers increase their search intensity.labor, search, recruitment, frictions, efficiency
