Implications for career counseling using Schlossberg’s Transition Theory with at-risk college students

Abstract: This roundtable will explain the basic tenets of Schlossberg’s Transition Theory, as well as its applicability and utility in working with at-risk college students. Case examples will be used to generate discussion on the theory’s use in this context as well as to facilitate conversation on further research and application. Proposal Summary: Provide program description (refer to instructions for more information regarding requirements). One of the main tasks in career counseling is to identify barriers, or career blocks, which are psychological, physiological, environmental, or interpersonal obstacles that prevent clients from making informed, meaningful career decisions. When academically at-risk college students seek out career counseling, they are most frequently in the middle of a difficult vocational transition that is related to their educational path. A theory of adult transitions exists called the Schlossberg Transition Theory, which provides a parsimonious and practical format for conceptualizing and counseling this population. While Schlossberg’s theory is not as well-known as traditional career counseling theories, it offers a means of quickly assessing a client’s situation, identifying key elements that are hindering successful transitions, and still allows room for the use of vocational assessments and traditional counseling techniques within the bounds of often brief counseling relationships. The purpose of this presentation is to show and discuss the utility of this model in career counseling, and its potential to be a bridge to reach clients, and more specifically, at-risk college students. The plan for the discussion will begin with a didactic portion to explain the theory, and the context in which it has been used. Next, a case example will be presented to illustrate the practical application of the theory which will include a template for how to use the theory in career counseling case conceptualization. Finally, semi-structured discussion questions will be used to elicit feedback and dialogue, as well as to generate ideas for future research

Measurement of the branching ratios of the Z0 into heavy quarks

We measure the hadronic branching ratios of the Z0 boson into heavy quarks: Rb=Gamma(Z0->bb)/Gamma(Z0->hadrons) and Rc=Gamma(Z0->cc/Gamma(Z0->hadrons) using a multi-tag technique. The measurement was performed using about 400,000 hadronic Z0 events recorded in the SLD experiment at SLAC between 1996 and 1998. The small and stable SLC beam spot and the CCD-based vertex detector were used to reconstruct bottom and charm hadron decay vertices with high efficiency and purity, which enables us to measure most efficiencies from data. We obtain, Rb=0.21604 +- 0.00098(stat.) +- 0.00073(syst.) -+ 0.00012(Rc) and, Rc= 0.1744 +- 0.0031(stat.) +- 0.0020(syst.) -+ 0.0006(Rb)Comment: 37 pages, 8 figures, to be submitted to Phys. Rev. D version 2: changed title to ratios, used common D production fractions for Rb and Rc and corrected Zgamma interference. Identical to PRD submissio

Direct Measurements of A_b and A_c using Vertex/Kaon Charge Tags at SLD

Exploiting the manipulation of the SLC electron-beam polarization, we present precise direct measurements of the parity violation parameters A_c and A_b in the Z boson - c quark and Z boson - b quark coupling. Quark/antiquark discrimination is accomplished via a unique algorithm that takes advantage of the precise SLD CCD vertex detector, employing the net charge of displaced vertices as well as the charge of kaons that emanate from those vertices. From the 1996-98 sample of 400,000 Z decays, produced with an average beam polarization of 73.4%, we find A_c = 0.673 +/- 0.029 (stat.) +/- 0.023 (syst.) and A_b = 0.919 +/- 0.018 (stat.) +/- 0.017 (syst.).Comment: 11 pages, 2 figures, 2 tables, to be submitted to Physical Review Letters; version 2 reflects changes suggested by the refere

Production of pi+, pi-, K+, K-, p and p-bar in Light (uds), c and b Jets from Z0 Decays

We present improved measurements of the differential production rates of stable charged particles in hadronic Z0 decays, and of charged pions, kaons and protons identified over a wide momentum range using the SLD Cherenkov Ring Imaging Detector. In addition to flavor-inclusive Z0 decays, measurements are made for Z0 decays into light (u, d, s), c and b primary flavors, selected using the upgraded Vertex Detector. Large differences between the flavors are observed that are qualitatively consistent with expectations based upon previously measured production and decay properties of heavy hadrons. These results are used to test the predictions of QCD in the Modified Leading Logarithm Approximation, with the ansatz of Local Parton-Hadron Duality, and the predictions of three models of the hadronization process. The light-flavor results provide improved tests of these predictions, as they do not include the contribution of heavy-hadron production and decay; the heavy-flavor results provide complementary model tests. In addition we have compared hadron and antihadron production in light quark (as opposed to antiquark) jets. Differences are observed at high momentum for all three charged hadron species, providing direct probes of leading particle effects, and stringent constraints on models.Comment: 44 pages, 14 figs; submitted to Phys.
