Incarceration, Relationships, and Belonging: Insights into the Experiences of Two Male Youth Recently Released from Custody Facilities
This paper explores the family, school, and community experiences of two male youth who had recently been released from custody facilities and how these experiences contributed to their sense of belonging and self-esteem. Addressing the limited literature on self-esteem and belonging of young men who had been incarcerated, the exploratory study considers key themes of trust, family, friendships, and perceptions of belonging and self-esteem which emerge from interviews and guided journal writing sessions. A key finding is that alternative literacy programs, such as journal writing, provide mechanisms to engage young men in building their self-esteem and sense of belonging. The paper concludes with recommendations for teachers, community program facilitators, and social workers to support marginalized youth after having been released from incarceration as they re-enter family and community life
A review of user interface adaption in current semantic web browsers
The semantic web is an example of an innumerable corpus because it contains innumerable subjects expressed using innumerable ontologies. This paper reviews current semantic web browsers to see if they can adaptively show meaningful data presentations to users. The paper also seeks to discover if current semantic web browsers provide a rich enough set of capabilities for future user interface work to be built upon
Radiative Corrections to Chargino Production with Polarized Beams
We show that radiative corrections to chargino production in
electron-positron annihilation with polarized beams can be large especially in
the case of right handed electrons. In addition, there is some dependency on
the squark masses that allows us to extract information about the squark
spectrum from the chargino production.Comment: 4 pages, including 4 figures. Talk given at Linear Collider Workshop

Non-universal Z' from SO(10) GUTs with vector-like family and the origin of neutrino masses
A gauge boson with mass around the (few) TeV scale is a popular example
of physics beyond the Standard Model (SM) and can be a fascinating remnant of a
Grand Unified Theory (GUT). Recently, models with non-universal couplings
to the SM fermions due to extra vector-like states have received attention as
potential explanations of the present , anomalies; this
includes GUT model proposals based on the group. In this
paper we further develop GUT models with a flavour non-universal low scale
and clarify several outstanding issues within them. First, we successfully
incorporate a realistic neutrino sector (with linear and/or inverse low scale
seesaw mechanism), which was so far a missing ingredient. Second, we
investigate in detail their compatibility with the ,
anomalies; we find that the anomalies do not have a consistent explanation
within such models. Third, we demonstrate that these models have other
compelling phenomenological features; we study the correlations between the
flavour violating processes of and - conversion in a muonic
atom, showing how a GUT imprint could manifest itself in experiments.Comment: Revised version, published in NPB. New material, general conclusions

Radiatively Corrected Chargino Pair Production at LEP2
One-loop radiative corrections to the production cross section of a pair of
light charginos in e+e- colliders are calculated within the MSSM. Top and
bottom quarks and squarks are considered in the loops, and they are
renormalized using the MS-bar scheme. If the center of mass energy is equal to
192 GeV, positive corrections typically of 10% to 15% are found when the squark
mass parameters are equal to 1 TeV.Comment: 6 pages, including 5 figures. Latex. Talk given by M.A.D. at the

Issues in knowledge representation to support maintainability: A case study in scientific data preparation
Scientific data preparation is the process of extracting usable scientific data from raw instrument data. This task involves noise detection (and subsequent noise classification and flagging or removal), extracting data from compressed forms, and construction of derivative or aggregate data (e.g. spectral densities or running averages). A software system called PIPE provides intelligent assistance to users developing scientific data preparation plans using a programming language called Master Plumber. PIPE provides this assistance capability by using a process description to create a dependency model of the scientific data preparation plan. This dependency model can then be used to verify syntactic and semantic constraints on processing steps to perform limited plan validation. PIPE also provides capabilities for using this model to assist in debugging faulty data preparation plans. In this case, the process model is used to focus the developer's attention upon those processing steps and data elements that were used in computing the faulty output values. Finally, the dependency model of a plan can be used to perform plan optimization and runtime estimation. These capabilities allow scientists to spend less time developing data preparation procedures and more time on scientific analysis tasks. Because the scientific data processing modules (called fittings) evolve to match scientists' needs, issues regarding maintainability are of prime importance in PIPE. This paper describes the PIPE system and describes how issues in maintainability affected the knowledge representation used in PIPE to capture knowledge about the behavior of fittings
Invariant approach to CP in family symmetry models
We propose the use of basis invariants, valid for any choice of CP
transformation, as a powerful approach to studying specific models of CP
violation in the presence of discrete family symmetries. We illustrate the
virtues of this approach for examples based on and family
symmetries. For , we show how to elegantly obtain several known results in
the literature. In we use the invariant approach to identify how
explicit (rather than spontaneous) CP violation arises, which is geometrical in
nature, i.e. persisting for arbitrary couplings in the Lagrangian.Comment: 4 pages plus references. v2: to be published in PR

Casimir probe based upon metallized high Q SiN nanomembrane resonator
We present the instrumentation and measurement scheme of a new Casimir force
probe that bridges Casimir force measurements at microscale and macroscale. A
metallized high Q silicon nitride nanomembrane resonator is employed as a
sensitive force probe. The high tensile stress present in the nanomembrane not
only enhances the quality factor but also maintains high flatness over large
area serving as the bottom electrode in a sphere-plane configuration. A fiber
interferometer is used to readout the oscillation of the nanomembrane and a
phase-locked loop scheme is applied to track the change of the resonance
frequency. Because of the high quality factor of the nanomembrane and the high
stability of the setup, a frequency resolution down to and a
corresponding force gradient resolution of 3 N/m is achieved. Besides
sensitive measurement of Casimir force, our measurement technique
simultaneously offers Kelvin probe measurement capability that allows in situ
imaging of the surface potentials
