When Aspiration Meets Opportunity: Examining Transitional Experiences of African American Males in College Readiness Programs

The lack of postsecondary success for African American males has garnered significant attention from academic scholars and public policy leaders. While this scholarship provides a strong portrait on issues related to African American males, there are still significant gaps to be addressed. Most notably, current research tends to focus on students entering four-year institutions and rarely presents student narratives about their educational experiences. The purpose of this study is to explore the experiences of African American males in various stages of transition from high school to their local community college. Students discuss three main areas—encouragement for their postsecondary aspirations, assistance with navigating multiple pathways to access, and persisting through stereotypes and perceived barriers. Discussion connects findings with theoretical frameworks to enhance our understanding of the experiences of this traditionally marginalized population.     

A new perspective on emotions

This paper reviews the recent history of the study of human emotions in psychology and traces the factors that have been responsible for a remarkable increase of interest in emotions, especially in human development. In particular, it traces the rise of the study of emotions as regulators of human behavior. A particularly clear and powerful illustration of the regulatory role of emotional expressions on behavior is the phenomenon of social referencing. This concept deals with the use of emotional information in another's facial, vocal or gestural expression to clarify uncertain situations. Research on social referencing is reviewed, showing the importance of social referencing with infants as young as 8.5 months. The clinical implications of the concept are briefly explored.     

Plato, Pascal, and the dynamics of personal knowledge

Abstract educational practices are to be based on proven scientific knowledge, not least because the function science has to perform in human culture consists of unifying practical skills and general beliefs, the episteme and the techne (Amsterdamski, 1975, pp. 43–44). Now, modern societies first of all presuppose regular and standardized ways of organizing both our concepts and our institutions. The explanatory schemata resulting from this standardization tend to destroy individualism and enchantment. But mathematics education is in fact the only place in which to treat the human subject’s relationship with mathematics. And that is what mathematics education is all about: make the human subject grow intellectually and as a person by means of mathematics. At first sight, mathematics, in its formal guise, seems the opposite of philosophy, because philosophy constructs concepts (meanings), whereas mathematics deals with extensions of concepts (sets). We shall, however, turn this problem into an instrument, using the complementarity of intensions and extensions of theoretical terms as our main device for discussing the relationship between philosophy and mathematics education. The complementarity of the “how” and the “what” of our representations outlines, in fact, the terrain on which epistemology and education are to meet.     

The Determinants of Artistic Innovation: Bringing in the Role of Organizations

This article deals with the determinants of artistic innovation by arts organizations. First, we define artistic innovation. Second, we review the literature on its determinants, identifying some gaps. In particular, we observe that existing research mostly focuses on macro-environmental factors and tends to ignore the role of the organizations themselves. Thus, drawing from the organizational literature on innovation we formulate testable propositions that relate organizational factors to artistic innovation. We hope that our focus on organizational factors contributes to a more comprehensive framework on the determinants of artistic innovation in particular and programming in general.     

Study of the deterioration products,gilding, and polychromy of the stones of the Scuola Grande Di San Marco's façade in Venice

The Scuola Grande di San Marco is one of the most outstanding Renaissance buildings in Venice. Destroyed by fire in 1485, the Scuola was reconstructed between 1487 and 1495 by Pietro Lombardi (and sons), together with Giovanni Buora and Mauro Codussi. The façade is considered one of the finest and most original exteriors of Venetian buildings and in particular features refined sculptural and painted decorations and a remarkable pictorial effect created by the extensive use of polychrome marbles and the false perspective view between the pilasters of the lower order. Most of the stone materials (Istrian and Verona red limestones, nero di Roveré, pavonazzetto toscano, Carrara marble and various reused antique marbles) present evident decay phenomena such as scaling, exfoliation, powdering, fissuring, salt efflorescence, black crusts, and artificial patinas of various kinds. The present study reports the results of petrographic and chemical laboratory analyses carried out in preparation for the conservation treatment of the building, in order to characterize the main micro- and macro-morphologies of decay and to identify the causes and mechanisms of deterioration as well as the nature and application technique of the polychromy, gilding, and patinas present on parts of the monumental Renaissance façade.     

Soothing pain-elicited distress in infants with swaddling and pacifiers

The effectiveness of pacifiers and swaddling in reducing pain-induced distress was compared in 2-week-old infants who underwent heel-sticks and 2-month-old infants who received injections. Crying, state, and heart rate were measured on 32 infants at each age during baseline, the stress of heel-stick or injection, and during 3-min soothing intervention and postintervention periods. At 2 weeks, infants' HR levels and crying declined significantly more rapidly in the pacifier than in the swaddling condition. At 2 months, both conditions produced similar rates of decline in HR and crying. At both ages, infants in the pacifier group spent significantly more time in an alert state than did swaddled infants. Following termination of the intervention at both ages, HR and crying tended to rebound more in the pacifier than in the swaddling group. Swaddling and pacifiers thus reduce pain-elicited distress differently.     

Theater

In this study, I examine the perspectives of preservice teachers enrolled in a multicultural education course at a large predominately White Midwestern university. Past research on the development of multicultural attitudes and knowledge of White preservice teachers is inconclusive. In an effort to examine the multicultural perspectives of preservice teachers, 13 prospective teachers enrolled in required semester-long multicultural education courses were regularly interviewed and observed. Results of the study indicate that preservice teacher perspectives toward diversity were influenced by their social and educational histories; popular culture, such as the news media and movies; and the traditional structure of the teacher education program. The single course had minimal impact on their perspectives. Recommendations include infusing a multicultural perspective throughout the teacher education program and the development of collaborations between the program and culturally diverse schools.     

A Mössbauer study of some coloured marbles (cipollino mandolato, rosso antico and fior di pesco): implications on the nature of their colour

⁵⁷Fe Mössbauer spectroscopy permits an explanation of the formation of the iron-bearing species present in three types of coloured marbles, known as cipollino mandolato, rosso antico and fior di pesco. Structural Fe²⁺ and Fe³⁺ located in silicates, together with the remains of weakly ferromagnetic hematite, arise from primary sediments. Fe²⁺ located in carbonates and anti-ferromagnetic hematite are formed by redox processes during marble formation. The relative contents of the iron species in the three types of marbles depend on the composition of the primary sediments and on local conditions during metamorphism. Knowledge of the type and amount of the iron species in marbles may help in the reconstruction of the redox processes, which took place during marble formation. The deviations of the Morin transition of the hematites play the role of genetic indicator because purity, crystallinity and the red hues of hematites in marbles can be related to the environment of formation.     

Double poling kinematic changes during the course of a long-distance race: effect of performance level

ABSTRACT

We aimed to evaluate the changes in double poling (DP) kinematics due to a long-distance cross-country skiing race in athletes with different performance levels. A total of 100 cross-country skiers, belonging to 10 different performance groups, were filmed on flat terrain 7 and 55 km after the start line, during a 58-km classical race. Cycle velocity, frequency and length decreased from the best to the lower-ranked group, while duty cycle increased (all P <.001). Between track sections, cycle velocity and length decreased, duty cycles increased (all P <.001) while frequency was unaltered (P =.782). Group*section interactions resulted for cycle velocity (P =.005). Considering all the participants together, % change in cycle velocity between sections correlated with % change in length and duty cycle (all P <.001). Thus i) skiers in better groups showed longer and more frequent cycles as well as shorter duty cycles than skiers in slower groups; ii) throughout the race all the groups maintained the same cycle frequency while decreasing cycle velocity and length; iii) better groups showed a lower reduction in cycle velocity. Individually, a low reduction in cycle velocity during the race related to the capacity to maintain long cycles and short duty cycles.     

Web geometry laboratory: case studies in Portugal and Serbia

The role of information and communication technologies (ICT) in education is well recognised – learning environments where the ICT features included are being proposed for many years now. The Web Geometry Laboratory (WGL) innovates in proposing a blended learning, collaborative and adaptive learning Web-environment for geometry. It integrates a well-known dynamic geometry system providing an adaptive environment where face-to-face activities can be combined with computer-mediated activities, in a collaborative or stand-alone, synchronous or asynchronous, classroom or homework way. The WGL collaborative environment allows each student to capitalise on one another's resources and skills. Its adaptive module gives to each teacher the ability to assess the geometric level of each student, allowing the teacher to build the individual profile and/or learning paths. In this paper we begin describing what are the goals that support the development of such an environment, the goals that support our beliefs in the usefulness of such an environment for the teaching and learning of geometry, after which we describe the environment and the case studies already conducted.
