At a time of great change for educational psychology services in England, this paper reviews current theories of leadership and proposes how an integration of key aspects of these can be applied to support a self review of leadership practice, both by individual leaders and by services. The message from current theory is that in the midst of complexity and rapid change, a primary focus on the h...

Previous research has shown that people differ in their implicit theories about the essential characteristics of intelligence and emotions. Some people believe these characteristics to be predetermined and immutable (entity theorists), whereas others believe that these characteristics can be changed through learning and behavior training (incremental theorists). The present study provides evide...

This article proposes a unified framework for understanding creative problem solving, namely, the explicit-implicit interaction theory. This new theory of creative problem solving constitutes an attempt at providing a more unified explanation of relevant phenomena (in part by reinterpreting/integrating various fragmentary existing theories of incubation and insight). The explicit-implicit inter...

BACKGROUND Despite a solid research base supporting evidence-based practices (EBPs) for addiction treatment such as contingency management and medication-assisted treatment, these services are rarely implemented and delivered in community-based addiction treatment programs in the USA. As a result, many clients do not benefit from the most current and efficacious treatments, resulting in reduced...

The purpose of the study was to gain a better understanding of the social and motivational antecedents of transformational leadership perceptions. Drawing on self-determination theory, a model was proposed in which perceptions of quality of relationships predict perceptions of transformational leadership behaviour through autonomous motivation and self-efficacy. Data were collected from 568 sch...

The current review examined teacher leadership research completed since York-Barr and Duke published the seminal review on teacher leadership in 2004. The review was undertaken to examine how teacher leadership is defined, how teacher leaders are prepared, their impact, and those factors that facilitate or inhibit teacher leaders’ work. Beyond this, the review considered theories informing teac...

Introduction Throughout history, humankind has examined the concept of leadership and attempted to grasp what it is, how it can be defined, and what makes a leader. The philosophy of leadership has evolved over time, within the context of culture and other influences, to represent a multitude of ideas. Theories of leadership have emerged to examine whether or not persons are born with leadershi...

Drawing on and extending prototype theories of creativity and leadership, we theorize that the expression of creative ideas may diminish judgments of leadership potential unless the charismatic leadership prototype is activated in the minds of social perceivers. Study 1shows creative idea expression is negatively related to perceptions of leadership potential in a sample of employees working in...

In order to elucidate the indirect effect by radiation on DNA base pairs, we investigate the mechanism for the attacking reaction of a hydroxyl radical (OH-radical) to the G-C and A-T base pairs, by the density functional theory (DFT) calculations. The effect of solvation on the mechanism is also revealed by performing the same DFT calculations under the continuum solvation approximation. We fi...

BACKGROUND More empirical work is needed to examine the dimensionality of personal epistemology and relations between those dimensions and motivational and strategic components of self-regulated learning. In particular, there is great need to investigate personal epistemology and its relation to self-regulated learning across cultures and academic contexts. Because the demarcation between perso...
