Integrating skill acquisition and perspective taking capacity in the development of leaders

This essay integrates approaches from three literatures to develop a model of leader development. Kanfer and Ackerman's (1989) episodic model of skill acquisition is combined with Kegan's approach to adult development to encompass development of transactional and transformational leadership. Importantly, feedback mechanisms are added to explain changes in individuals'intellectual capacities, values, and beliefs over time. This framework provides a summary of what is known about the processes underlying developmental change in how leaders understand and act on their environment and provides specific directions for future research.     

What do teenagers want? What do teenagers need?

It is widely accepted that adolescence is a developmental phase fraught with challenges, yet in the 1990s, teenagers face unique demands and difficulties. Dilemmas such as increased violence, drug and alcohol use, sexual involvement and AIDS pose problems not only for the teens themselves, but also for their families, teachers, health care providers and other caregivers.This article reports on the qualitative findings extracted from a study of over 3,700 teenagers from urban, suburban, and small city settings, describing the array of difficulties teenagers face today. The themes which emerged from the students' comments offer a compelling portrait of life as a teenager in the 1990s and help shape an agenda for understanding and responding to these myriad needsThis research was supported by grants from the Ohio Department of Mental Health (#93,1058A), Treu-Mart Fund, Nord Family Foundation, and the University at Albany Faculty Research Awards Program.     

Energizing the ordinary: Biographical work and the future in stroke recovery narratives

Historically, the life course has been constructed as an organized and linear temporal progression. This holds true in various disciplines from education, to psychology, to counseling. The foundation of a life unfolding through temporal categorizations is documented in textbooks and theories that straddle these disciplines as well as many others, including the sociology of health and illness, which has often conceptualized the illness experience as embedded in a recovery trajectory.Here, we take this to task. Using Gubrium and Holstein's [Sociol. Inq. 65 (1995) 207; Gubrium, J., & Holstein, J., (1997). The new language of qualitative method. New York: Oxford University Press] analytic vocabulary of biographical work, we analyze narratives of stroke survivors by emphasizing the ordinary resources used as discursive foundations for the narrative production of the future in illness. Ordinary resources focused on include God and spirituality, comorbidities, and activity and leisure. The discussion is embedded in overarching concerns with “healthy aging” in gerontology and geriatrics.     

Racial Prejudice and Fear of Criminal Victimization by Strangers in Public Settings*

In this article we examine the extent to which racial (antiblack) prejudice conditions the effect of the race of strangers encountered in public settings on whites' fear of being crime victims in those settings. We hypothesize that encountering black strangers. as opposed to white strangers, evokes greater fear of being a crime victim in prejudiced whites than in whites who are not prejudiced. Data collected using the factorial survey method support this hypothesis. These results indicate that research dealing with whites' fear of being crime victims in public settings needs to consider both the race of potential criminals and the racial attitudes of potential victims.     

Strengths First: An Empowering Case Management Model for Multiethnic Sexual Minority Youth

This article (1) describes the development of a strengths-based case management (SBCM) model for multiethnic sexual minority youths; (2) provides a profile of participant risks and strengths; and (3) discusses critical considerations for implementation with this population. Participants (N = 162) reported complex risks such as family rejection as well as personal strengths. SBCM is a promising intervention that provides opportunities to bridge the unique gaps in service for this vulnerable population. Strategies to incorporate strengths into program assessments and address issues such as family engagement and service delivery challenges are offered.     

NONLINEAR TUBE-FITTING FOR THE ANALYSIS OF ANATOMICAL AND FUNCTIONAL STRUCTURES

We are concerned with the estimation of the exterior surface and interior summaries of tube-shaped anatomical structures. This interest is motivated by two distinct scientific goals, one dealing with the distribution of HIV microbicide in the colon and the other with measuring degradation in white-matter tracts in the brain. Our problem is posed as the estimation of the support of a distribution in three dimensions from a sample from that distribution, possibly measured with error. We propose a novel tube-fitting algorithm to construct such estimators. Further, we conduct a simulation study to aid in the choice of a key parameter of the algorithm, and we test our algorithm with validation study tailored to the motivating data sets. Finally, we apply the tube-fitting algorithm to a colon image produced by single photon emission computed tomography (SPECT) and to a white-matter tract image produced using diffusion tensor imaging (DTI).     

‘Sit in the corner and don’t eat the crayons’: postgraduates with dyslexia and the dominant ‘lexic’ discourse

The lack of cultural diversity in higher education is recognised by policy objectives and a current focus on the development of widening participation for a range of students, including those with disabilities. Amongst this group are those with dyslexia who might previously have been disenfranchised from formal education and under‐represented within it. This paper explores the personal narratives and learner histories of six postgraduates and academics with dyslexia from their earliest memories of learning to their present experiences. It examines how literacy, as a dominant form of discourse, has defined concepts of academic ability resulting in the early exclusion of these learners from formal education. It is argued that this dominant discourse can be challenged by non‐authorised, informal learning resulting in stories of resistance.     

Predicting treatment efficacy via quantitative magnetic resonance imaging: a Bayesian joint model

The prognosis for patients with high grade gliomas is poor, with a median survival of 1 year. Treatment efficacy assessment is typically unavailable until 5-6 months post diagnosis. Investigators hypothesize that quantitative magnetic resonance imaging can assess treatment efficacy 3 weeks after therapy starts, thereby allowing salvage treatments to begin earlier. The purpose of this work is to build a predictive model of treatment efficacy by using quantitative magnetic resonance imaging data and to assess its performance. The outcome is 1-year survival status. We propose a joint, two-stage Bayesian model. In stage I, we smooth the image data with a multivariate spatiotemporal pairwise difference prior. We propose four summary statistics that are functionals of posterior parameters from the first-stage model. In stage II, these statistics enter a generalized non-linear model as predictors of survival status. We use the probit link and a multivariate adaptive regression spline basis. Gibbs sampling and reversible jump Markov chain Monte Carlo methods are applied iteratively between the two stages to estimate the posterior distribution. Through both simulation studies and model performance comparisons we find that we can achieve higher overall correct classification rates by accounting for the spatiotemporal correlation in the images and by allowing for a more complex and flexible decision boundary provided by the generalized non-linear model.
