Generative Roles: Assessing Sustained Involvement in Generativity

Abstract Generative roles refer to observable, behavioral community positions that embody aspects of teaching and nurturing that are central to the concept of generativity. Two studies are presented that describe generative roles in a community sample and provide psychometric data for a short index of generative roles. The first study also provides reliability and validity data from a second informant. The second study examines generative roles at different stages of adolescence and adulthood. Participants were asked 8 yes/no questions about a variety of community roles. The validity of the GRI was supported by significant correlations with the Loyola Generativity Scale, a widely used measure of generative concern (r=.33), and measures of related constructs. The correlations were similar across age categories. The Generative Roles Index has good psychometric qualities and complements existing measures of generativity by providing behavioral, observable data on roles

Stellar Polarimetry: Where Are We and Where Are We Going?

On the final day of the Stellar Polarimetry conference, participants split up into three "breakout sessions" to discuss the future of the field in the areas of instrumentation, upcoming opportunities, and community priorities. This contribution compiles the major recommendations arising from each breakout session. We hope that the polarimetric community will find these ideas useful as we consider how to maintain the vitality of polarimetry in the coming years.Comment: 7 pages, published in proceedings of "Stellar Polarimetry: From Birth to Death" (Madison, WI, June 2011

The Success of Gay–Straight Alliances in Waterloo Region, Ontario: A Confluence of Political and Social Factors

This article outlines how gay–straight alliances (GSAs) work to connect youth with community resources, and outlines the political and social context of GSAs in Waterloo Region, Ontario, Canada. Fifteen individuals (youth, teachers, and a lesbian, gay, bisexual, transgender, and queer [LGBTQ] youth service provider) participated in interviews about the role of GSAs in creating supportive school environments for LGBTQ youth and their allies. Analyses of the interview data found that, apart from providing direct support to LGBTQ students, GSAs in Waterloo Region decrease isolation by connecting youth with other LGBTQ community members, events, and resources. This article discusses how the confluence of government and school board policy and community agency support facilitates the implementation, maintenance, and success of GSAs

The Lability and Relative Reactivities of Organic Radicals

Studies have been made of the rates of many reactions involving organometallic compounds, by means of the color test of Gilman and Schulze. These rate studies comprise: (1) the relative reactivities of a variety of compounds towards a typical organometallic compound; (2) the relative reactivities of a series of related compounds like nitriles or azo compounds with an organometallic compound; (3) and, the differences in rate of reaction of a series of organometallic compounds towards other compounds.. The same method has been used in a study of the effect of concentration, temperature and catalysts on reaction rates. Also, it has been shown to be of service in a study of the mechanism of reactions, like the two-stage conversion of esters to ketones to tertiary alcohols; and the lability and relative electronegativities of radicals

Return on the Federal Investment in Student Financial Aid: An Assessment for the High School Class of 1972

It can be argued that the public investment in student financial aid should be evaluated based on the tax revenue returns that result from this investment. While this is not the only basis on which student aid can be justified in the budget process, this approach does have merit, especially given the large federal deficit. This article develops a model for estimating the tax revenue returns from gains in educational attainment that are attributable to student financial aid. This study examines the impact of student aid on access and persistence. It is estimated that the net present value of the tax returns on each dollar of federal expenditures on student aid for students in the high school class of 1980 was $4.30, using reasonable economic assumptions. The authors conclude that student financial aid generates a positive return to the federal budget, a research finding that merits consideration in the budget process

Cloning of terminal transferase cDNA by antibody screening

A cDNA library was prepared from a terminal deoxynucleotidyltransferase-containing thymoma in the phage vector λgt11. By screening plaques with anti-terminal transferase antibody, positive clones were identified of which some had β-galactosidase-cDNA fusion proteins identifiable after electrophoretic fractionation by immunoblotting with anti-terminal transferase antibody. The predominant class of cross-hybridizing clones was determined to represent cDNA for terminal transferase by showing that one representative clone hybridized to a 2200-nucleotide mRNA in close-matched enzyme-positive but not to enzyme-negative cells and that the cDNA selected a mRNA that translated to give a protein of the size and antigenic characteristics of terminal transferase. Only a small amount of genomic DNA hybridized to the longest available clone, indicating that the sequence is virtually unique in the mouse genome

AfrOBIS: a marine biogeographic information system for sub-Saharan Africa

AfrOBIS is one of 11 global nodes of the Ocean Biogeographic Information System (OBIS), a freely accessible network of databases collating marine data in support of the Census of Marine Life.Versatile graphic products, provided by OBIS, can be used to display the data. To date, AfrOBIS has loaded about 3.2 million records of more than 23 000 species located mainly in the seas around southern Africa. This forms part of the 13.2 million records of more than 80 000 species currently stored in OBIS. Scouting for South African data has been successful, whereas locating records in other African countries has been much less so

Values Narratives for Personal Growth: Formative Evaluation of the Laws of Life Essay Program

Evidence that even very brief writing exercises can change the way people see themselves and promote more positive mental and physical health has led to increased interest in their use in school settings and elsewhere. To date, however, research designs rely heavily on samples of college students and experimental studies of writing tasks carried out in the lab. There has been less investigation of the potential impact of more naturally occurring expressive writing exercises that exist in places like schools and that focus on adolescents. The current study was a process evaluation of the Laws of Life Essay, a values-based narrative program that was part of participants’ secondary school experience. It examined participants’ views of the impact of the program on their personal growth and, given the age range of participants, allowed for process evaluation of its perceived short- and long-term effects. Qualitative, semistructured interviews with 55 adolescent and adult participants were collected. Themes in participants’ responses included the importance of reflection and reappraisal of values, adversity, and relationships. Participants also discussed the importance of an audience for their writing, a novel finding that suggests one possible way to increase the impact of other narrative programs. Participants described variability in their engagement with expressive writing. This is one of the few studies that examined participants’ own views of the value of expressive writing and their responses suggest directions for future research and implications for designing expressive writing tasks to support social emotional learning and character education in schools and promote well-being at key developmental moments
