Using body donor demographics to assist the implementation of donation programs in Brazil

The use of human material in anatomy education depends upon the generosity of body donors. However, little is known regarding the demographics of body donors in Brazil, where voluntary body donation is a relatively rare phenomenon. Hence, the aim of the present study was to elucidate the demographic profile of applicants to the Body Donation Program (BDP) at the Federal University of Health Sciences of Porto Alegre in Brazil, as well as to assess whether the observed characteristics of body donors are unique to that sample, or if they merely reflect the characteristics of the regional population. Information derived from the specific forms filled out by donors between January 2008 and June 2016 at the time of registration were collected. Data from 416 forms were analyzed. Based on this study, the typical applicant in Brazil is typically a white female (67.4%), over 60 years of age (60.3%), unmarried or single (70.6%), affiliated with a religious group (89.1%), of middle class background (40.4%), who has completed high school and/or holds a university degree (93.8%). The motivation of donors was, in most cases, an altruistic gesture, represented by the desire to help society and science. Elucidating these demographic characteristics of potential donors may help identify the target public to which information regarding body donation campaigns could be directed.

Father Involvement During Early Childhood and Its Association with Children's Early Learning: A Meta-Analysis

Research Findings: In the present meta-analysis, information from 21 studies (representing 22 separate samples) was pooled across a 10-year period (1998–2008). Across 2 primary dimensions of direct father involvement (frequency of positive engagement activities and aspects of parenting quality) and 5 dimensions of children's early learning (representing social and cognitive domains), findings revealed small to moderate associations. Among group differences tested to further explain the relationships between these constructs, residential status and the ethnic/racial identification of fathers' surfaced as significant moderators, whereas income status was only meaningful at the trend level. Practice or Policy: In recent years, national attention has increased concerning the important influence of fathers on children's development. Concurrently, national interest has turned to the early childhood period as marking a major transition for young children, during which children are confronted with new and diverse developmental challenges that require emotional, social, and cognitive competence across their home and school environments. Although there is a growing body of research on fatherhood and father involvement, this literature has not been examined systematically to determine the strength of associations between specific dimensions of father involvement and young children's early learning that could inform the efforts of early childhood practitioners and family engagement programming decisions.     

In and of the City: Theory of Action and the NYU Partnership School Program

This article explores the theory of action underlying New York University's (NYU's) Partnership Schools Program—explaining in the process what a theory of action is, and how it can be constructed for other innovations in other contexts. NYU's Partnership Program involves 23 schools, K-12, spanning several of New York City's most economically disadvantaged neighborhoods. It operates on the basis of what the authors call “mutual self-interest” and exploits what they call “complementarity.” The authors illuminate the program's original as well as its evolving intentions, and the environmental conditions necessary to enact them and to sustain the program over a decade. They also describe the program's core design elements, with a view to how these may be replicated elsewhere. Finally, they look closely at the Partnership's theory of action in action, employing action research data to portray a meeting where professors and teachers discuss the teacher education residency experiment they have collaboratively launched.     

La aproximación neuropsicológica a la dislexia evolutiva II: Lateralización hemisférica y aplicaciones educativas

Resumen

Se aborda en este trabajo la dominancia o lateralización hemisférica cerebral, en cuanto posible factor etiológico de interés para la neuropsicología de la dislexia evolutiva. Se precisan las relaciones con la lateralidad manual y se revisan, a la luz de los conocimientos actuales, los conceptos legados por Broca y Orton. En este sentido, también se revisa la teoría de la dominancia desde el principio (Kinsbourne) en cuanto contrapuesta a la teoría de la progresiva lateralización hemisférica en la ontogenia (Lenneberg). Los principales modelos de dislexia basados en la organización cerebral se agrupan según hagan referencia a la integración interhemisférica, a la especialización hemisférica o a la integración intersensorial. Como aplicación a la educación, se proponen algunas consideraciones generales derivadas del enfoque neuropsicológico y se revisa críticamente el carácter generalizador de una educación basada en la hemisfericidad.     

Cognitive processes and math performance: a study with children at third grade of basic education

The present study aims to examine the relationship between cognitive factors and mathematical achievement in primary education. Participants were 103 Portuguese third grade students, aged 8 and 9. All participants completed a battery for working memory (WMTB-C), a test of general intelligence (Raven's Progressive Color Matrices), a selective attention test (d2), and mathematical exercises (arithmetic story problems and measurement skills). Data suggested significant correlations between math performance, executive, visuospatial sketchpad and g factor. Our findings suggest the importance of the cognitive factors in two mathematical domains considered. In consonance with the research in this area, we conclude that working memory (WM) assumes an important role in different math curricular achievements.     

Neonatal Stepping in Relation to Terrestrial Optic Flow

This experiment examined whether newborn stepping, a primitive form of bipedal locomotion, could be modulated by optical flow. Forty-eight 3-day-old infants were exposed to optical flows that were projected onto a horizontal surface above which the infants were suspended. Significantly more air steps were elicited by exposure to a terrestrial optical flow specifying forward translation than by a rotating optical flow or a static optical pattern. Thus, a rudimentary coupling between optical flow and stepping is present at birth, suggesting a precocious capacity in the newborn to perceive and utilize visual information specifying self-motion. The findings may help the early diagnosis of infants with visual or visual-motor deficits and the development of visually based interventions for disabled infants.     

The intangibles’ mindset of CFOs’ and corporate performance

This paper aims to analyze the companies’ view about the financial valuation of intangibles relevance and its influence on corporate performance. Based on the theory of resources, the role of intangibles in business competitiveness is justified. The traditional factors of production have become secondary, while the success is primarily based on the development and utilization of intangible resources. One of the main problems in managing the intangibles appears to be that, there is a general lack of information about them. Therefore, financial valuation of intangibles will result in significant benefits to the organization that will help determine business strategy, process design as well providing competitive advantage. It follows the hypothesis of this work, the greater known about their intangibles and the greater sensitivity to the financial valuation of them, the better performance. To achieve this objective, a field study is done, doing telephone calls to Basque Country companies’ financial managers.
