University of Virginia Graduate Mentoring Institute: A Model Program for Graduate Student Success

This study examines an innovative model program for the mentorship of diverse graduate students entitled the Inter-Ethnic/Interdisciplinary Mentoring Institute for Graduate Education (i.e., Mentoring Institute), which was established by the Graduate Student Diversity Programs in the Office of the Vice President for Research at the University of Virginia (UVa). The Mentoring Institute was created to promote an inclusive environment for graduate students from diverse backgrounds as well as to provide support for and increase the number of students of color who successfully matriculate and graduate from UVa. A comprehensive program evaluation was conducted that assesses the mentoring experiences of UVa graduate students who participate in the Mentoring Institute. The evaluation data reveals how graduate students’ involvement in the Mentoring Institute has positively impacted their academic and social experiences as well as their feelings of connectedness to UVa's professional community. The evaluation also assesses ongoing activities, professional trainings, workshops, and other support mechanisms provided for graduate students by the Mentoring Institute. In all, graduate students who participated in the Mentoring Institute evaluation indicated that the program has contributed significantly to their academic success, social well being, and feelings of connectedness to the UVa graduate school community. This study should particularly benefit administrators, faculty, students, and higher education professionals who are interested in multicultural graduate student development at predominately White institutions of higher education.
Neuropsychological Findings in Two Children Diagnosed with Hamartoses: Evidence of a NLD Phenotypic Profile

Hamartoses (HM) are defined as disorders involving nonneoplastic tissue overgrowth. Studies have examined the neuropsychological profiles of children with common HM, such as neurofibromatosis type 1. Limited information is known regarding neuropsychological profiles of rare HM such as Osteochondromatosis Syndrome (OS) and Klippel-Trenaunay Syndrome (KTS). The current investigation is, to our knowledge, the first attempt to define the cognitive phenotypes in two boys with OS and KTS. Results revealed significantly greater impairments involving sensorimotor and visuospatial skills, while verbal memory and language skills appeared relatively preserved. Significant neurobehavioral problems and marked social difficulties were evident. These findings suggest that these syndromes are on a Nonverbal Learning Disorder (NLD) continuum, with varying degrees of severity.
Elevation of erythropoietin levels in association with Wilms' tumor.

THE OCCURRENCE of polycythemia in association with various diseases has been frequently recorded. Renal malignancies, uterine myomata, hemangioblastomas and hepatic cell carcinomas have been the malignant tumors most frequently involved.1-4Recent reports have also established the occurrence of polycythemia in association with undifferentiated carcinoma of the lung.5Hematologic remission subsequent to treatment with surgery, radiotherapy, or chemotherapy has been documented in some of these cases. This report presents observations of what we believe to be the first patient with Wilms' tumor to be associated with polycythemia. Plasma from this patient had an increased level of erythropoietin; metastatic nodules in the lung were homogenized and separated, and the supernatant fluid had erythropoietin activity. Methods of Investigation Presurgical and postsurgical erythropoietin levels were determined by bioassay in starved rats. Female Sprague-Dawley rats weighing approximately 200 gm each were starved for 96 hours. Thirty and 54 hours after starvation was instituted,
Multi-spot ignition in type Ia supernova models

We present a systematic survey of the capabilities of type Ia supernova explosion models starting from a number of flame seeds distributed around the center of the white dwarf star. To this end we greatly improved the resolution of the numerical simulations in the initial stages. This novel numerical approach facilitates a detailed study of multi-spot ignition scenarios with up to hundreds of ignition sparks. Two-dimensional simulations are shown to be inappropriate to study the effects of initial flame configurations. Based on a set of three-dimensional models, we conclude that multi-spot ignition scenarios may improve type Ia supernova models towards better agreement with observations. The achievable effect reaches a maximum at a limited number of flame ignition kernels as shown by the numerical models and corroborated by a simple dimensional analysis.
Condições de vida e itinerários terapêuticos de quilombolas de Goiás

The aim of this study was to investigate living conditions and therapeutic paths of two quilombola communities residing in the State of Goias: Almeidas (rural community), Jardim Cascata (urban community). We conducted a quantitative and qualitative study through questionnaire, semi-structured interviews with key informants and observation of reality. Four visits were made to each community in the years 2010 and 2011. Concerning to the general characteristics, the communities presented a low level of education, low income and lack of basic sanitation. People at those communities mobilize popular, religious and biomedical knowledge in their treatments. At Almeidas, people self medicate using homemade and conventional medication simultaneously. There is an elderly lady who prepares homemade treatments. The people at Jardim Cascata use mainly conventional self-medication. Family support networks are more intense in Almeidas than Jardim Cascata. In both communities, health services are often closed due staff turnover and poor infrastructure. Moreover, the two communities have historical determinations based to a lack of attention from the public sector and marginalization of the poor population.
Parallel Dimensions in Child, Adolescent, and Adult Analytic Work

SUMMARY This paper begins with the proposal that there are certain essential processes of therapy, including play as the renegotiation of self-other relationships that are fully present in work with children. This leads to a discussion of historical material about the use of play in analytic work with children, associated with the emergence of ideas about the analytic work with children as a “less pure” form of analysis. The paper then presents a theoretical discussion of play as a continuous and basic function in psychoanalysis, where play is seen as a way of engagement, which includes both the negotiation of paradox and the capacity for the use of metaphor in treatment. This is associated with a brief discussion of play as non-linear versus non-play as linear, reflected in more general theories about essentialist versus more relational, constructivist approaches to treatment. Vignettes from analytic work conducted with two young persons in residential care then illustrate how play can function as an essential process of therapy.
Similarities and differences in leisure conceptualizations between Japan and Canada and between two Japanese leisure-like terms

This study investigated similarities and differences in leisure conceptualizations between Japan and Canada and between two Japanese leisure-like terms: yoka and rejā. To address these purposes, we developed the Leisure Ten Statements Test (LTST). The LTST asks people to provide 10 open-ended responses to a prompt (e.g., “Leisure _____”). Responses from university students in Japan and Canada were classified, and then statistical analyses were conducted on the proportions of the 26 resulting categories. Results indicated that: (1) leisure conceptualizations differed not only between Japan and Canada but also within Japan depending on terminologies; (2) the loanword rejā has different meanings from its original English word, leisure, suggesting that it has adapted Japanese cultural contexts; and (3) the Japanese leisure-like term that best compares with the English word leisure varies depending on which specific aspect of leisure is of interest.
Voltage, efficiency calculation and measurement of low power rectenna rectifying circuit

In this paper, we present zero-bias Schottky diode and rectifier circuit models for a low power (/spl les/ 0 dBm) rectenna rectifying circuit. These models rely primarily on data obtained from the diode characteristic curve measurement. The zero-bias Schottky diode model provides diode parameters at the desired output DC current level to be matched with the antenna so that optimum power transfer from the antenna to the diode takes place. The rectifier circuit model provides an equivalent circuit model for the rectenna rectifying circuit to calculate RF to DC conversion efficiency at the desired output DC current level.
Can Students be Taught to Study? An Evaluation of a Study‐Skill Programme Directed at First Year Students at the University of Bergen

Abstract Raaheim, A. 1984. Can Students be Taught to Study? An Evaluation of a Study‐Skill Programme Directed at First Year Students at the University of Bergen. Scandinavian Journal of Educational Research 28, 9‐15. An account is given of an experiment where twenty‐one first year students were trained in using certain study techniques and followed through their first examination at the university. When their results were compared with those of a group of students who did not take part in this training, statistically significant differences were found. This is taken to indicate that the training has been successful, and the author argues that elaborate study‐skills can be learned and that these skills may facilitate learning and understanding.
A feature-preserving simplification based on integral invariant clustering

Detailed models are required in computer graphics for many applications. However, considering the processing and transporting time, it is often necessary to approximate these models. In this paper we provide an effective simplification method for mesh models, which decreases the size of complex models and keeps visual features. We employ the integral invariant to distinguish the desired features on the models with different scales, then use the k-means clustering algorithm to find the fixed feature vertex cluster in which the vertices are kept approximately identical by our best, finally provide a weighting map to guide the simplifications. The proposed algorithm by this paper provides significant improvement on feature-preserving, especially sharp feature-preserving, and it can also be combined with other mesh simplification schemes to improve their effects.
Bounded Model Checking for the Existential Fragment of TCTL-G and Diagonal Timed Automata

Bounded Model Checking (BMC) is one of the well known SAT based symbolic model checking techniques. It consists in searching for a counterexample of a particular length, and generating a propositional formula that is satisfiable iff such a counterexample exists. The BMC method is feasible for the various classes of temporal logic; in particular it is feasible for TECTL (the existential fragment of Time Computation Tree Logic) and Diagonal-free Timed Automata. The main contribution of the paper is to show that the concept of Bounded Model Checking can be extended to deal with TECTL_{-G} properties of Diagonal Timed Automata. We have implemented our new BMC algorithm, and we present preliminary experimental results, which demonstrate the efficiency of the method.
FAK overexpression and p53 mutations are highly correlated in human breast cancer

Focal adhesion kinase (FAK) is overexpressed in a number of tumors, including breast cancer. Another marker of breast cancer tumorigenesis is the tumor suppressor gene p53 that is frequently mutated in breast cancer. In the present study, our aim was to find a correlation between FAK overexpression, p53 expression and mutation status in a population‐based series of invasive breast cancer tumors from the Carolina Breast Cancer Study. Immunohistochemical analyses of 622 breast cancer tumors revealed that expression of FAK and p53 were highly correlated (p = 0.0002) and FAK positive tumors were 1.8 times more likely to be p53 positive compared to FAK negative tumors [odds ratio (OR) = 1.8; 95% Confidence Interval (CI) 1.2–2.8, adjusted for age, race and stage at diagnosis]. Tumors positive for p53 expression showed higher intensity of FAK staining (p < 0.0001) and higher percent of FAK positive staining (p < 0.0005). From the same study, we evaluated 596 breast tumors for mutations in the p53 gene, using single strand conformational polymorphism and sequencing. Statistical analyses were performed to determine the correlation between p53 mutation status and FAK expression in these tumors. We found that FAK expression and p53 mutation were positively correlated (p < 0.0001) and FAK positive tumors were 2.5 times more likely to be p53 mutation positive compared to FAK negative tumors [adjusted OR = 2.5, 95% CI 1.6–3.9]. This is the first analysis demonstrating a high correlation between FAK expression and p53 mutations in a population‐based series of breast tumors. © 2009 UICC
Absence of functional and structural abnormalities associated with expression of EGFP in the retina.

PURPOSE The present study was undertaken to evaluate the effect of uniform EGFP expression on retinal morphology and function. METHODS Electroretinography (ERG) was used to evaluate the recovery of scotopic a- and b-wave amplitudes after a single 137-cd.sec/m2 flash exposure. The cellular distribution of enhanced green fluorescent protein (EGFP) in the retina and its effect on retinal morphology were evaluated by fluorescence microscopy and histology, respectively. To evaluate its effect on retinal sensitivity to light, EGFP-expressing and control mice were exposed to constant light for 76 hours (3500 lux), and eyes were assessed functionally and structurally at 3 weeks after light exposure. RESULTS Fluorescence microscopy showed a pronounced EGFP expression in the photoreceptor cell bodies and inner segments. ERG analysis revealed no significant differences in either a- or b-wave amplitudes or recovery between EGFP(+/-) and control mice under dark- or light-adapted conditions. Histologic assessment at as late as 4 months of age showed no difference in retinal morphology or photoreceptor nuclei count in EGFP(+/-) mice when compared with nontransgenic littermates. In addition, evaluation of animals, 3 weeks after constant light exposure, showed no difference between ERG amplitudes, recovery of the scotopic ERG response, or retinal morphology between EGFP(+/-) mice and control animals. CONCLUSIONS Functional and morphologic evidence shows that long-term, high, uniform levels of EGFP expression have no deleterious effect on the mouse retina. This data demonstrates the safety of EGFP use as an indicator of viral transduction in retinal gene therapy.
The professionalisation of sports coaching: relations of power, resistance and compliance

This paper examines the changing landscape of the professionalisation of sports coaching and is presented in response to the dearth of empirical research and peer-reviewed literature existing within the field. This absence or ‘lack’ has, in turn, created a political context in which the discourses that inhabit transitions towards professionalism are becoming increasingly rigid and inflexible. Policies too, have exacerbated this situation, creating imposed reforms that have sought to homogenise coaching practice and further gloss over cultural difference and diversity. While volunteerism is often regarded as a socially embedded activity, and one that is part of the UK's long-established coaching tradition, still there remains an ambition to transform coaching into a form of certified, professionalised activity. That is, a notion of professionalism with clearly benchmarked standards, novel forms of commercial engagement and ever-present systems of formal accreditation. Out of which has evolved a series of treatments prescribing somewhat standardised solutions to otherwise unique and individualised professional challenges. Against this backdrop, this paper adopts a more critical orientation towards the debate on the professionalisation of sports coaching. It examines the tensions, power and resistance that are manifested in practice across different areas of sport, and moves to understand some of the key differences emerging between contemporary reforms, situated practice and socially embedded coaching traditions. Drawing extensively on Bourdieurian and Foucauldian philosophy, the analysis reflects upon the experiences of coaches and stakeholders operating at the levels of voluntary and community-based practice in the north-west of England. It examines notions of resistance and compliance in situ, external factors and policies that have impacted the field, and analyses the complexities that inhabit the profession of sports coaching as a whole.
Gender expectations and student achievement

Few students are able to escape the effects of gender, ethnic, and racial biases which continue to exist in today's schools. The GESA Program (Gender/Ethnic/Racial Expectations and Student Achievement) is a staff development program designed to aid teachers in identifying and removing classroom biases. GESA utilizes peer coaching and a team approach to assist teachers in using positive interactions equitably with all students. As a result of participating in the GESA program, teachers report positive effects upon student attitudes and achievement.
Rainbow nation or new racism? Theorizing race and identity formation in South African higher education

This paper explores both the personal narratives of a group of black and white undergraduate students and the institutional discourse at one historically white and Afrikaans medium university now undergoing its own transformation in post‐apartheid South Africa. It considers how students talk about their actual experiences and the micro‐realties of their personal biographies, what this reveals about how they construct and reconstruct race and identity, and how discourses of race and racialized identities are being reproduced or transformed under new historical and institutional conditions of possibility. The focus is twofold: on the one hand on the contradictions of institutional discourse which both formally admits black students but may subtly work to exclude them as well; and on the other on the friendships that students develop as just one exemplar of how race works itself out biographically and personally. The particular issue is to understand institutional and individual ‘default identities’ which wo.
Interaction effects in multiple regression

This monograph is concerned primarily with the statistical analysis of moderated relationships or as they are more commonly known interaction effects where all variables involved are continuous in nature. The focus is on analyzing interaction effects in the context of multiple regression and structural equation analyses. There currently exists a great deal of confusion about the analysis of moderated relationships involving continuous variables. The statistical and substantive literatures are replete with contradictory advice and admonitions about the best way to test models involving moderated relationships. Further the relevant statistical literature is scattered throughout a range of disciplines including sociology psychology political science economics biology and statistics. The major purpose of this monograph is to bring together this rather diverse literature and to explicate the central issues involved in conducting analyses of moderated relationships involving continuous variables. The principal finding is that interaction analysis is most straightforward when it is theoretically motivated; theory guides the specification of appropriate interaction models using multiple regression analysis. Traditional product terms with continuous variables assess interaction of a specific form namely bilinear interactions. The authors organize their analysis around 3 principal questions: 1) given the sample data can it be inferred that an interaction effect exists in the population; 2) if so what is the strength of the effect; and 3) if so what is the nature of the effect? When formulating research to test for interaction effects one should consider issues related to sample size (for purposes of power analysis) levels of measurement measurement error potential multicollinearity and other methodological/substantive issues discussed above. The monograph concludes with 10 empirical applications that have used multiple regression analysis for the analysis of moderated relationships.
The Baryonic Mass Function of Spiral Galaxies. Clues to Galaxy Formation and to the Nature of Damped Lyman Alpha Clouds

We compute the baryonic mass function, ψS(Mb) d log Mb, of disc galaxies using the luminosity functions and baryonic mass-to-light ratios reliable for this goal. On scales from 108 M⊙ to 1011 M⊙ this function is featureless, . Outside this mass range ψS is a strong inverse function of Mb. The contributions to the baryon density from objects of different mass indicate that spirals have a characteristic mass scale at , around which more than 50 per cent of the total baryonic mass is concentrated. The integral value, , confirms, to a higher accuracy, previous evidence that the fraction of BBN baryons locked in disc galaxies is negligible and matches that of high-z damped Lyα systems (DLAs). We investigate the scenario where DLAs are the progenitors of present-day spirals, and find a simple relationship between their masses and H i column densities by which the DLA mass function closely matches that of spiral discs.
The effects of 43 hours of sleep deprivation on executive control functions: Event-related potentials in a visual Go/No go task

The aim of this study was to investigate how 43 hours of total sleep deprivation (TSD) influences executive control functions. Forty participants were assigned to either a TSD or a control group (no sleep deprivation; NSD group) and both groups were tested at 2:00am on day 3 (after 43 hours of sleep deprivation for the TSD group). Electroencephalogram (EEG) recordings were taken using 32 electrodes while a Go/No go task was administered. The amplitude of the N2 was significantly larger on the No-go trials as compared to the Go trials. In the No-go trials, the amplitudes of the No go-N2 and the No go-P3 were smaller in the TSD group than in the control group in terms of prolonged latencies. The mean correct reaction time, number of misses, and the false-alarm rate were also significantly longer and increased in the NSD group. Results indicated that executive control functions were noticeable impaired after 43 hours of sleep deprivation.
