We have obtained and analyzed UBVRI CCD frames of the young, 4-10 Myr, open cluster NGC 3293 and the surrounding field in order to study its stellar content and determine the cluster's IMF. We found significantly fewer lower mass stars, M≤2.5M ⊙, than expected. This is particularly so if a single age for the cluster of 4.6 Myr is adopted as derived from fitting evolutionary models to the upper main sequence. Some intermediate-mass stars near the main sequence in the HR diagram imply an age for the cluster of about 10 Myr. When compared with the Scalo (The stellar initial mass function. ASP conference series, vol. 24, p. 201, 1998) IMF scaled to the cluster IMF in the intermediate mass range, 2.5≤M/M ⊙≤8.0 where there is good agreement, the high mass stars have a distinctly flatter IMF, indicating an over abundance of these stars, and there is a sharp turnover in the distribution at lower masses. The radial density distribution of cluster stars in the massive and intermediate mass regimes indicate that these stars are more concentrated to the cluster core whereas the lower-mass stars show little concentration. We suggest that this is evidence supporting the formation of massive stars through accretion and/or coagulation processes in denser cluster cores at the expense of the lower mass proto-stars. © 2007 Springer Science+Business Media B.V.

School disciplinary policies and practices are essential features of life in U.S. schools. Conventional approaches to school discipline - including conduct codes and security methods, suspension, corporal punishment, and teachers' methods of managing student behaviors - rely primarily on deterrence, control, and punishment to maintain order. However, approximately 40 years of research, chiefly in education and psychology, has demonstrated that these policies and practices are often associated with and can contribute to increased disorder in schools and behavioral and academic problems among students. Furthermore, school discipline is sometimes administered prejudicially to those students who may be the most vulnerable. School social workers and all social workers working with children and youths can help schools adopt effective and nonpunitive disciplinary approaches. Key professional actions include advocacy for schoolchildren subject to unfair and overly punitive discipline; educating teachers and administrators about the potential harm associated with conventional disciplinary practices; educating school personnel about effective, nonpunitive approaches; and creating a public campaign to generate popular support for the reform of iatrogenic school disciplinary practices. © 2006 National Association of Social Workers.

Research has identified a relationship between school disciplinary actions and poor academic and psychosocial functioning of students subjected to them. The ways in which school discipline is a direct contributor to students' academic and psychosocial difficulty needs to be further established empirically. Several theories, based in existing research and theory in sociology of education and educational psychology, have been proposed to explain the school discipline - student dysfunction relationship. They generally suggest three pathways: disciplinary actions may contribute to students' psychological problems; student misbehavior may be encouraged through ineffective and unintentionally paradoxical learning experiences; and disciplinary practices may damage students' relationship with school. School social workers and others working with children who have been disciplined at school can use these research findings and theories as an assessment framework to guide their interventions.The awareness of the iatrogenic potential of school discipline and informed assessment can support a range of evidence-based alternatives to school discipline. © 2006 National Association of Social Workers.

Growth of GaN and AlGaInN nanowires using metalorganic chemical vapor deposition (MOCVD) is investigated. It is determined that surface kinetics play an important role in non-equilibrium synthesis process such as MOCVD, in contrast to near-equilibrium synthesis by hotwall furnace reactor. Examination of crystallographic properties of GaN nanowires reveals preferential growth directions which are perpendicular to the c-axis. Such a tendency is analyzed by both thermodynamic and kinetic arguments and attributed to the minimization of (side wall) surface energy. Spontaneous formation of Al(Ga)N/GaN coaxial nanowires with distinct emission at 370 nm is observed. It is identified that the interplay between surface kinetics and thermodynamics facilitates the catalytic growth of GaN core while a limited surface diffusion of Al adatoms leads to nonselective, vapor-solid growth of Al(Ga)N sheath. The knowledge of crystallographic alignment is applied to the formation of arrayed GaN nanowires in both vertical and horizontal fashions, resulting in potentially new paradigms for creating nanoscale devices. © 2006 Materials Research Society.

Research pertaining to issues on educational services for individuals with disabilities in developing countries is scarce. The purpose of this article is to two fold: first, to contribute to the already existing literature, and, secondly, and perhaps more importantly, to provide a foundation for prospective readers to better understand literature regarding educational services for students with mental retardation. This article guides the reader to understand the perspectives towards students with mental retardation, discusses the definition and causes of this condition, and discusses issues pertaining to the identification, assessment and evaluation of these students in Kenya. The core of the article contains a discussion of the various placement options available for this population along with the curriculum in operation in the various settings. Existing barriers to effectively serving this population in Kenya and in other developing countries is also discussed.

This article employs a dialogic approach, in the parlance of Bakhtin, to explore the ways in which a school's "medium," its primary language of instruction, has become a major category of identity in North India. Many people describe themselves and others by invoking attendance at either a Hindi- or English-medium school. The first task of this article is to account for what Bakhtin calls "centripetal forces" that enable people at different positions in terms of class or school experience to use a common duality of Hindiversus English-medium and its attendant social resonances. The second task is to account for the abilities of a teacher to question the inevitability of the medium divide and to radically reframe what is important about schooling. Her abilities derive, in part, from her experiences with schools, attesting to Bakhtin's insight that centripetal forces in language are never total, and that centrifugal forces arise from complex engagements with institutions. © 2006 by the American Anthropological Association.

Each fall, the Tunxis Library hosts a party. Usually thematic, sometimes didactic, and always cerebral, the library uses the party to communicate our “party line” to the entire campus community: we are here to make your life easier. It's particularly effective when delivered at the start of the semester, before the unrelenting rhythm of classes, committee work, and meetings has begun. Showing the campus community that the library is here to support them is our core theme, wrapped in a party context. Our goal is to create a party that jump-starts the fall semester for everyone. In this article, we describe our most recent parties, focusing how we develop, plan, and execute these promotional initiatives, with little money, but plenty of creativity and teamwork. © 2005 by The Haworth Press, Inc.

Sexual violation of children has been a long standing problem that has a wide range of impact upon the victim, her/his family, the community where the family lives and our society as a whole. Traumatic incest, in particular, is an abuse of power, a challenge to the child's sense of trust in people and a thief of childhood. This article will explore the intricate issues surrounding the incest relationship between fathers and their child daughters and provide a discussion of current therapeutic interventions.

A map of France is included in a manuscript, dated to around 1460, entitled A tous nobles, which contains a historical account and genealogy of the French kings. The map was produced in the wake of the Hundred Years War, when conflict with the English challenged both French identity and territory. The map, however, smooths over a century of war to reveal a nation both strong and independent. Through the mapmaker's selection of places, and his use of fluvial boundaries to define the area concerned, he has created an image of France shaped by ideology and history that is wholly in keeping with its location in the manuscript, where the renaming of Gaul as France is described. The map reveals the territory of France to be a critical link between the mythical past and the political present. This connection between history and territory, also reiterated in the text itself, is presented in a graphic format that may be related to contemporary practice of using maps along with legal documents in the resolution of territorial disputes. Seen in the light of the king's claim to the lands ruled by his ancestors, the map thus constitutes a rare medieval example of French national identity expressed in relation to French territory. © 2006 Imago Mundi Ltd.

A data management system has been developed for the Connecticut State University (CSU) Lidar Collaboratory to facilitate user authentication, scheduling of remote lidar instrumentation control sessions, storage and retrieval of lidar datasets and generation of new data products. In addition to providing for efficient archival and retrieval of lidar data products, a major design goal of the data management system is to support collaborative, multidisciplinary, atmospheric sciences research projects. In this paper, we describe the framework of the CSU Lidar Collaboratory data management system and how the system interacts with the data acquisition and data analysis software.

Despite the availability of a spin Hamiltonian for the Gd3Ga5O12 garnet (GGG) for over 25 years, there has so far been little theoretical insight regarding the many unusual low temperature properties of GGG. Here we investigate GGG in zero magnetic field using mean-field theory. We reproduce the spin liquid-like correlations and, most importantly, explain the positions of the sharp peaks seen in powder neutron diffraction experiments. We show that it is crucial to treat accurately the long-range nature of the magnetic dipolar interactions to allow for a determination of the small exchange energy scales involved in the selection of the experimental ordering wave vector. Our results show that the incommensurate order in GGG is classical in nature, intrinsic to the microscopic spin Hamiltonian and not caused by weak disorder. © 2006 The American Physical Society.
