Reading the World of University : What Counts?

This paper will address the issues encountered by first year students in reading and reshaping the culture of university. The interim findings of a six year study will be dismantled in order to uncover what counts in the experience of first year university and the ramifications for educational practice and discourse. Feedback from staff continues to indicate that there is growing disparity between their expectations of first year students and student performance in areas such as independent learning, research skills, academic reading and writing, as well as the use of new technologies. There also seems to be a gap between the students’ perceptions of their own abilities with respect to literacy practices and the demands placed on them in the tertiary setting. Dialogic critical reflection on the part of both students and staff empowers these individuals to read the world from multiple perspectives and to reshape future directions

Psychiatric characterization of children with genetic causes of hyperandrogenism

Objective: Very little is known about the mental health status in children with genetic causes of hyperandrogenism. This study sought to characterize psychiatric morbidity in this group. Design/methods: Children (8-18 years) with the diagnosis of classic congenital adrenal hyperplasia (CAH) or familial male precocious puberty (FMPP) underwent a semi-structured psychiatric interview, the Kiddie Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version. According to sex and the literature, incidence of identified psychopathology was compared between the two endocrinological groups. We evaluated 72 patients: 54 CAH (21 females) and 18 FMPP. Results: Twenty-four (44.4%) CAH patients and 10 (55.6%) FMPP patients met the criteria for at least one lifetime psychiatric diagnosis. Attention-deficit hyperactivity disorder (ADHD) was present in 18.2% of CAH males, 44.4% of FMPP males, and one case (4.8%) in CAH females. A high rate of anxiety disorders was also found in all the three groups (17-21%). Relative to females with CAH, the FMPP patients exhibited higher rates of ADHD. Age at diagnosis and the treatment modalities were not associated with psychopathology. Rates of psychiatric disorder, specifically ADHD and anxiety disorders, were higher than in the general population. Conclusion: Although anxiety disorders may occur at an increased rate in children with chronic illness, androgens may contribute to higher risk for psychopathology in pediatric patients with genetic cause of excess androgen. Early diagnosis and treatment of childhood hyperandrogenism is essential for optimal development. The results suggest that assessment for psychiatric disorders should be part of the routine evaluation of these patients

Invisible design: exploring insights and ideas through ambiguous film scenarios

Invisible Design is a technique for generating insights and ideas with workshop participants in the early stages of concept development. It involves the creation of ambiguous films in which characters discuss a technology that is not directly shown. The technique builds on previous work in HCI on scenarios, persona, theatre, film and ambiguity. The Invisible Design approach is illustrated with three examples from unrelated projects; Biometric Daemon, Panini and Smart Money. The paper presents a qualitative analysis of data from a series of workshops where these Invisible Designs were discussed. The analysis outlines responses to the films in terms of; existing problems, concerns with imagined technologies and design speculation. It is argued that Invisible Design can help to create a space for critical and creative dialogue during participatory concept development

Increasing the presence of African Americans in the arts administration field: models from the for-profit sector

There is resurgence on the conversation around racial diversity in the arts and culture workforce. African-Americans are particularly underrepresented relative to population in cities like New York and Los Angeles. There is a call for shared strategies and models to increase the pipeline of diverse arts administrators. The journalism and business, when faced with similar diversity challenges thirty years ago, created unique, mission-specific organizations committed to increasing racial diversity in their fields. The author conducted research, interviews and surveys on three of the most successful programs, The LEAD Business Program’s pre-college summer institutes; the Urban Alliance’s work study program for high school students; and The Emma Bowen Foundation's multi-year media/ journalism internship and scholarship program for college students. The author concludes with recommendations as follows (1) The LEAD Business Program pre-college summer institutes and university arts presenting programs should collaborate; (2) K-12 arts education programs should expose students to the business of the arts; (3) Arts service organizations like the Association for Arts Professionals (APAP), Americans for the Arts and Grantmakers in the Arts (GIA) must lead action-oriented convenings that affirm the need for data collection, the value of racial diversity in the arts workforce and connect stakeholders and potential funders to programs like the Urban Alliance and Urban Arts Alliance; (4) establish a database of internships, highlighting diversity internships, and market it to African American civic, social and educational groups.M.S., Arts Administration -- Drexel University, 201

Phylogenetic profiling of the Arabidopsis thaliana proteome: what proteins distinguish plants from other organisms?

BACKGROUND: The availability of the complete genome sequence of Arabidopsis thaliana together with those of other organisms provides an opportunity to decipher the genetic factors that define plant form and function. To begin this task, we have classified the nuclear protein-coding genes of Arabidopsis thaliana on the basis of their pattern of sequence similarity to organisms across the three domains of life. RESULTS: We identified 3,848 Arabidopsis proteins that are likely to be found solely within the plant lineage. More than half of these plant-specific proteins are of unknown function, emphasizing the general lack of knowledge of processes unique to plants. Plant-specific proteins that are membrane-associated and/or targeted to the mitochondria or chloroplasts are the most poorly characterized. Analyses of microarray data indicate that genes coding for plant-specific proteins, but not evolutionarily conserved proteins, are more likely to be expressed in an organ-specific manner. A large proportion (13%) of plant-specific proteins are transcription factors, whereas other basic cellular processes are under-represented, suggesting that evolution of plant-specific control of gene expression contributed to making plants different from other eukaryotes. CONCLUSIONS: We identified and characterized the Arabidopsis proteins that are most likely to be plant-specific. Our results provide a genome-wide assessment that supports the hypothesis that evolution of higher plant complexity and diversity is related to the evolution of regulatory mechanisms. Because proteins that are unique to the green plant lineage will not be studied in other model systems, they should be attractive priorities for future studies
