Providing effective administrative leadership that has a positive impact on student achievement often is problematic for school principals. Research suggests that collaboration and shared decision making are functions of effective leadership, and according to the premises of effective school instructional leadership, leadership should change with…

Aim: This study investigated the reliability and validity of the Barry-Albright Dystonia Scale (BADS), the Burke-Fahn-Marsden Movement Scale (BFMMS), and the Unified Dystonia Rating Scale (UDRS) in patients with bilateral dystonic cerebral palsy (CP). Method: Three raters independently scored videotapes of 10 patients (five males, five females;…

NEO instruments are widely used to assess Big Five personality factors, but confirmatory factor analyses (CFAs) conducted at the item level do not support their a priori structure due, in part, to the overly restrictive CFA assumptions. We demonstrate that exploratory structural equation modeling (ESEM), an integration of CFA and exploratory…

This meta-analysis addresses whether achievement goal researchers are using different labels for the same constructs or putting the same labels on different constructs. We systematically examined whether conceptual and methodological differences in the measurement of achievement goals moderated achievement goal intercorrelations and relationships…

Racial microaggressions are subtle statements and behaviors that unconsciously communicate denigrating messages to people of color. In recent years, a theoretical taxonomy and subsequent qualitative studies have introduced the types of microaggressions that people of color experience. In the present study, college- and Internet-based samples of…

It has been claimed that Autism Spectrum Disorder (ASD) is characterized by a limited ability to process perceptual stimuli in reference to the contextual information of the percept. Such a connection between a nonholistic processing style and behavioral traits associated with ASD is thought to exist also within the neurotypical population albeit…

Bullying victimization is part of the adolescent experience in most societies, yet little is known about its consequences. In this article we utilize a multisite, longitudinal data set to examine the effects of being bullied. We also explore definitional and measurement issues that confound this line of research. While some researchers have relied…

This article documents the typological occurrence and interactions of two seemingly independent error patterns, namely Velar Fronting and Labial Harmony, in a cross-sectional investigation of the sound systems of 235 children with phonological delays (ages 3;0 to 7;9). The results revealed that the occurrence of Labial Harmony depends on the…

Research has shown that English as a foreign language (EFL) learners in Taiwan fall into two peaks of the curve. This is to say, learners can be classified into two major groups: those who perform quite well on standardized tests, such as college entrance examinations, and those who perform poorly. From a socioeconomic perspective, the correlation…

This study extends recent findings of a relationship between the relative age of students among their peers and their probability of disability classification. Using three nationally representative surveys spanning 1988-2004 and grades K-10, we find that an additional month of relative age decreases the likelihood of receiving special education…

Background: Opponent-process theories of externalizing disorders (ExD) attribute them to some combination of overactive reward processing systems and/or underactive behavior inhibition systems. Reward processing has been indexed by recruitment of incentive-motivational neurocircuitry of the ventral striatum (VS), including nucleus accumbens…

This paper reviews the new directions in institutional research on undergraduate racial/ethnic and socioeconomic diversity at the University of California, Berkeley. The use of SERU/UCUES and other web-based census surveys has made possible more detailed and extensive analysis of student diversity. Included is research on an expanded number of…

The purpose of this study is to track the diachronic development of exemplar clusters formed by the adjectives in the Spanish expression of becoming "quedar(se)" + ADJ (e.g. "quedar(se) solo" "to be left alone", "quedar(se) espantado" "to get scared"). This approach applies the same system of analysis used by Bybee & Eddington (2006) in their…

Conceptual knowledge of our world is represented in semantic memory in terms of concepts and semantic relations between concepts. We used functional magnetic resonance imaging (fMRI) to examine the cortical regions underlying the processing of sequential and taxonomic relations. Participants were presented verbal cues and performed three tasks:…

There is much debate on the merits and pitfalls of standardized tests for college admission, with questions regarding the format (multiple-choice versus constructed response), cognitive complexity, and content of these assessments (achievement versus aptitude) at the forefront of the discussion. This study addressed these questions by…
