This book is…

This paper investigates the effects of meaning dominance in the time-course of activation for ambiguous words out of context in a second language (L2) based on two models: the ordered access model, where the most frequent dominant meaning is always accessed first, and the multiple access model, where dominant and subordinate meanings are…

Twelve years after passage of No Child Left Behind, the Program for International Student Assessment (PISA) report on 510,000 fifteen year-olds in 65 countries ranked the U. S. 31st in math, 24th in science, and 21st in literacy. U.S. Secretary of Education Arne Duncan commenting on the PISA report said that the brutal truth must serve as a…

U.S. Supreme Court justices and other federal judges are, effectively, appointed for life, with no built-in check on their cognitive functioning as they approach old age. There is about a century of research on aging and intelligence that shows the vulnerability of processing speed, fluid reasoning, visual-spatial processing, and working memory to…

This paper presents a conceptual framework for predicting whether power will have a unifying or subversive effect in specific organizational cultures. The Cultural Interaction Model of Leadership and Power (LP-CIM) asserts cultural norms constrain what leadership approaches will be successful in particular organizational contexts. These…

Studies of the interaction between professional and academic staff in leadership in higher education institutions have focused on distributed leadership.

Organizations are faced with solving increasingly complex problems. Addressing these issues requires effective leadership that can facilitate a collaborative problem solving approach where multiple perspectives are leveraged. In this conceptual paper, we critique the effectiveness of earlier leadership models in tackling complex organizational…

In recent years, substantial improvements were obtained in the effectiveness of data driven algorithms to validate the mapping of items to skills, or the Q-matrix. In the current study we use ensemble algorithms on top of existing Q-matrix refinement algorithms to improve their performance. We combine the boosting technique with a decision tree.…

The literature provides multiple measures of diversity along a single demographic dimension, but when it comes to studying the interaction of multiple diversity types (e.g. age, gender, and race), the field of useable measures diminishes. We present the use of decision trees as a machine learning technique to automatically identify the…

Language switch costs have been explored less in receptive tasks than in productive tasks, and previous studies have produced mixed findings with regard to switch cost symmetry and the relationship of switch costs to executive function. To address these unresolved gaps, one hundred Chinese-English bilingual adults completed a bilingual lexical…

This paper introduces a new term and concept to the leadership discourse: Subtractive Leadership. As an extension of the distributive leadership model, the notion of subtractive leadership refers to a leadership style that detracts from organizational culture and productivity. Subtractive leadership fails to embrace and balance the characteristics…

Greenfield's subjectivist approach to the construction and interpretation of social reality is examined and applied to school organizations in an attempt to demonstrate that such organizations may be advantageously viewed as entities constructed and sustained by ideas in people's minds. The path to understanding schools and their administration…
