Conceptual frame for selecting individual psychotherapy in the schools

PSYCHOLOGY IN THE SCHOOLS, Issue 3 2009
Tammy L. Hughes
Psychotherapy is a service-delivery that is provided for both general and special education students. This manuscript examines a conceptual framework for determing when to employ psychotherapy within the school-based setting. Decisions are informed by the relationship between problem behavior, therapeutic techniques, short-term outcomes, and overall child development. Both the individual needs of students and the cumulative body of evidence regarding treatment effectiveness are required for intervention selection. The school psychologists' unique training in psychology and education affords the opportunity to effectively use psychotherapy to enhance the academic and social development of children. © 2009 Wiley Periodicals, Inc.

Organizational identity strength, identification, and commitment and their relationships to turnover intention: does organizational hierarchy matter?

JOURNAL OF ORGANIZATIONAL BEHAVIOR, Issue 5 2006
Michael S. Cole
In the present study we sought to clarify the functional distinctions between organization identity strength, organizational identification, and organizational commitment. Data were obtained from 10,948 employees of a large steel manufacturer. First, confirmatory factor analysis was used to test the discriminant validity of the three focal constructs. Next, drawing on research that suggests hierarchical differentiation may influence individuals' conceptual frame of reference, we examined each focal construct's measurement equivalence across three hierarchical levels (officers, n,=,1,056, middle-management, n,=,1049, workers, n,=,1050). Finally, multigroup structural equation modeling was used to simultaneously estimate the between-group correlations between turnover intention and organization identity strength, organizational identification, and organizational commitment. Results indicated that (a) the measures used to reflect the three focal constructs were empirically distinct, (b) the focal constructs were conceptually equivalent across hierarchical levels, and (c) the pattern of correlations with turnover intention was different for employees with management responsibilities versus workers with no management responsibility. The present findings suggest perceptions of a strong organizational identity, organizational identification, and organizational commitment may influence employees' turnover intention in unique ways, depending on their hierarchical level within the organization.

Becoming a Hurdler: How Learning Settings Afford Identities

ANTHROPOLOGY & EDUCATION QUARTERLY, Issue 1 2009
Na'ilah Suad Nasir
In this article, we present a model for thinking about how learning settings provide resources for the development of the practice-linked identities of participants, drawing on data from a study on an African American high school track and field team. What does it mean to make an identity available in the context of a learning setting? In this article, we draw on current theories in anthropology, psychology, sociology, and sociocultural theory to develop a conceptual frame that might be helpful in addressing these questions. We focus on how individuals are offered (and how they take up) identities in cultural activities. We define three types of identity resources that were made available to student-athletes learning to run track and explore how they took shape in teaching and learning interactions in track.,[identity, learning, African American students, culture] [source]

Generation of branched actin networks: assembly and regulation of the N-WASP and WAVE molecular machines

BIOESSAYS, Issue 2 2010
Emmanuel Derivery
Abstract The Arp2/3 complex is a molecular machine that generates branched actin networks responsible for membrane remodeling during cell migration, endocytosis, and other morphogenetic events. This machine requires activators, which themselves are multiprotein complexes. This review focuses on recent advances concerning the assembly of stable complexes containing the most-studied activators, N-WASP and WAVE proteins, and the level of regulation that is provided by these complexes. N-WASP is the paradigmatic auto-inhibited protein, which is activated by a conformational opening. Even though this regulation has been successfully reconstituted in vitro with isolated N-WASP, the native dimeric complex with a WIP family protein has unique additional properties. WAVE proteins are part of a pentameric complex, whose basal state and activated state when bound to the Rac GTPase were recently clarified. Moreover, this review attempts to put together diverse observations concerning the WAVE complex in the conceptual frame of an in vivo assembly pathway that has gained support from the recent identification of a precursor.

Cross-constituency Organizing in Canadian Unions

BRITISH JOURNAL OF INDUSTRIAL RELATIONS, Issue 2 2008
Linda Briskin
This article explores cross-constituency organizing inside three Canadian unions that involves dual, parallel and integrated structures. It assesses these approaches with reference to the conceptual frame of intersectional political practice. In particular, this study highlights the institutionalization of intersectionality through constitutional, organizational and representational intersectionality. The paradigm of autonomy and integration is used to identify effective mechanisms for cross-constituency vehicles. Cross-constituency organizing is a form of coalition-building inside unions It is a vehicle for building solidarities across identities and advancing equity organizing in Canadian unions that supports, at one and the same time, union revitalization and the union equity project.

PKSP-dependent reduction of phagolysosome fusion and intracellular kill of Aspergillus fumigatus conidia by human monocyte-derived macrophages

CELLULAR MICROBIOLOGY, Issue 12 2002
Bernhard Jahn
Summary Previously, we described the isolation of an Aspergillus fumigatus mutant producing non-pigmented conidia, as a result of a defective polyketide synthase gene, pksP (polyketide synthase involved in pigment biosynthesis). The virulence of the pksP mutant was attenuated in a murine animal infection model and its conidia showed enhanced susceptibility towards damage by monocytes in vitro. Because macrophage-mediated killing is critical for host resistance to aspergillosis, the interaction of both grey-green wild-type conidia and white pksP mutant conidia with human monocyte-derived macrophages (MDM) was studied with respect to intracellular processing of ingested conidia. After phagocytosis, the percentage of wild-type conidia residing in an acidic environment was approximately fivefold lower than that observed for non-pigmented pksP mutant conidia. The phagolysosome formation, as assessed by co-localization of LAMP-1 and cathepsin D with ingested conidia, was significantly lower for wild-type conidia compared with pksP mutant conidia. Furthermore, the intracellular kill of pksP mutant conidia was significantly higher than of wild-type conidia, which was markedly increased by chloroquine, a known enhancer of phagolysosome fusion. Taken together, these findings suggest that the presence of a functional pksP gene in A. fumigatus conidia is associated with an inhibition of phagolysosome fusion in human MDM. These data show for the first time that a fungus has the capability to inhibit the fusion of the phagosome with the lysosome. This finding might help explain the attenuated virulence of pksP mutant strains in a murine animal model and provides a conceptual frame to understand the virulence of A. fumigatus. [source]
