The current study represents the first longitudinal investigation of the potential effects of breastfeeding duration on maternal sensitivity over the following decade. This study also examined whether infant attachment security at 24 months would mediate longitudinal relations between breastfeeding duration and changes in maternal sensitivity over…

Treatment effect estimates from a "regression discontinuity design" (RDD) have high internal validity. However, the arguments that support the design apply to a subpopulation that is narrower and usually different from the population of substantive interest in evaluation research. The disconnect between RDD population and the…

The study reveals that the positive correlation between formal education and job training (complementarity) has weakened during the 2000s. Using U.S. Census Bureau data from the Survey of Income and Program Participation, the study finds that although workers in all categories of educational attainment felt the decline, the effects were strongest…

The shortage of qualified human capital is a major impediment to development. In the field of international development cooperation, training programs (TPs) have been widely employed to enhance the capacity of workforces in developing countries. This paper investigates the conditions in which these programs can contribute not only to individual…

The existence of a race-based stigma has been well documented among adolescents and young adults within higher educational settings; however, similar studies among students at historically Black universities are rare. Specifically, the 'acting white' accusation is a common, and yet seldom openly discussed phenomenon that exist within the African…

Graduate and doctoral schools around the world struggle to shorten the long time to degree and to prevent high dropout rates. While most of previous research studied individual determinants of PhD completion, we analyze the impact of two structural reforms of the doctoral program on thesis completion at a selective European graduate school.…

A well established finding is that the cognitive component of test anxiety (worry) is negatively related to examination performance. The present study examined how 3 self-beliefs (academic buoyancy, perceived control, and test competence) moderated the strength of the relationship between worry and examination performance in a sample of 270 final…

Mature epistemic beliefs underlie higher-order thinking and learning outcomes. Previous studies have established that epistemic beliefs predict task-specific performance. However, there is mixed evidence regarding the relationships between such beliefs and course-level academic performance. This study investigated whether disciplinary type ('soft'…

Within the undergraduate mathematics curriculum, the topic of simple least-squares linear regression is often first encountered in multi-variable calculus where the line of best fit is obtained by using partial derivatives to find the slope and y-intercept of the line that minimizes the residual sum of squares. A markedly different approach from…

In this study we examine the determinants of and the relationship among economic knowledge, epistemological beliefs, and extrinsic and intrinsic motivation over the course of undergraduate studies in a sample of students of business and economics at a university in Germany. We found economic knowledge increased over the course of studies,…

In a recent contribution, Redding and Schott [2003. "Distance, Skill Deepening and Development: Will Peripheral Countries Ever Get Rich?" "Journal of Development Economics": 72 (2): 515-541. doi:10.1016/S0304-3878(03)00118-4] add human capital to a two sector NEG model, highlighting that remoteness represents a penalty that…

Background/Context: Although numerous studies have emerged shedding light on community college student success, the enduring role of social capital is often overlooked. Furthermore, when conceptualizing social capital in the community college context and its diverse student population, age represents a unique form of diversity in these…

I employ ordered probit regression and a new instrumental variable to compare the Fall 2015 parental satisfaction survey results of open-enrollment charters to district-conversion charters. Choice status in Arkansas charter schools is largely beneficial to parental satisfaction. Specifically, parents with children in open-enrollment charters had…

Purpose: The purpose of this systematic review and meta-analysis was to establish a baseline of the vowel and consonant identification scores in prelingually and postlingually deaf users of multichannel cochlear implants (CIs) tested with consonant-vowel-consonant and vowel-consonant-vowel nonsense syllables. Method: Six electronic databases were…

Background: We investigated predictors of self-efficacy to cope with stress in diverse populations with stressful life experiences. We also examined the association between predictors of coping self-efficacy and the different copying strategies adapted by study participants. Purpose: The purpose of this study was to determine the relationship…
