    Unemployment Among Young Adults: Exploring Employer-Led Solutions

    Get PDF
    Younger workers consistently experience higher unemployment and less job stability than older workers. Yet the dramatic deterioration in employment outcomes among younger workers during and since the Great Recession creates new urgency about developing more effective bridges into full-time employment for young people, especially those with less than a bachelor's degree. Improving the employment status of young adults and helping employers meet workforce needs are complementary goals. Designing strategies to achieve them requires insight into the supply and demand sides of the labor market: both the characteristics of young people and their typical routes into employment as well as the demand for entry-level orkers and the market forces that shape employer decisions about hiring and investing in skill development. A quantitative and qualitative inquiry focused on the metropolitan areas of Chicago, Ill. and Louisville, Ky

    D vs d: CP Violation in Beta Decay and Electric Dipole Moments

    Full text link
    The T-odd correlation coefficient D in nuclear beta decay probes CP violation in many theories beyond the Standard Model. We provide an analysis for how large D can be in light of constraints from electric dipole moment (EDM) searches. We argue that the neutron EDM d_n currently provides the strongest constraint on D, which is 10 - 10^3 times stronger than current direct limits on D (depending on the model). In particular, contributions to D in leptoquark models (previously regarded as "EDM safe") are more constrained than previously thought. Bounds on D can be weakened only by fine-tuned cancellations or if theoretical uncertainties are larger than estimated in d_n. We also study implications for D from mercury and deuteron EDMs.Comment: 17 pages, 6 figure

The bnnmn doing the search (the "user') ,i,,, to find an item (the "target') that best meets his/her nxluimn~ts. The user's mental model of the tazget is called the "sentr, h goal'. Our testbed browsing applic~ion is software rense. The h'bmx7 is a collection of object-oriented softwa~. An item in the library is a "class" containing locally defined "instance vaziables" and "methods'. A class also inherits the va6ables and methods of its superclass in the inhesitance hletat~y. A class's functionality is detetm/ned by its methods. The aim of browsing is to find the class whose functionality is closest to the requinKi functional/ty. In our browsing system the user is initially presented with a list of all the claues in the h'bnwy. As browsing proceeds additional class lists and method lists are created by the nsef's actions. To apply an operator to a class, the user selects the class from any available class list and then specifies the operator to be applied. An example of a clau-hased operator is "Defined Methods"; when applied to class C this creates a list of the methods C defines locally. To apply an operator to a method is a two step process. Hnt one must select the method in the method fist produced by "Defmed Methods'. ~ "opens" the method in a window that is used for inspecting a method's details. To apply an operate, the user must "magk" one of more methods in this window and then specLCy the operator-For example the operator "Used By" creates a list of classes oniesed by the degnm to which each uses ill the cun, ently marked methods. A cless's score is based on the si~ of the madmd methods' names to the nmnes of the methods that are called by the class's own methods

    MRI-LINAC: A transformative technology in radiation oncology

    Get PDF
    Advances in radiotherapy technologies have enabled more precise target guidance, improved treatment verification, and greater control and versatility in radiation delivery. Amongst the recent novel technologies, Magnetic Resonance Imaging (MRI) guided radiotherapy (MRgRT) may hold the greatest potential to improve the therapeutic gains of image-guided delivery of radiation dose. The ability of the MRI linear accelerator (LINAC) to image tumors and organs with on-table MRI, to manage organ motion and dose delivery in real-time, and to adapt the radiotherapy plan on the day of treatment while the patient is on the table are major advances relative to current conventional radiation treatments. These advanced techniques demand efficient coordination and communication between members of the treatment team. MRgRT could fundamentally transform the radiotherapy delivery process within radiation oncology centers through the reorganization of the patient and treatment team workflow process. However, the MRgRT technology currently is limited by accessibility due to the cost of capital investment and the time and personnel allocation needed for each fractional treatment and the unclear clinical benefit compared to conventional radiotherapy platforms. As the technology evolves and becomes more widely available, we present the case that MRgRT has the potential to become a widely utilized treatment platform and transform the radiation oncology treatment process just as earlier disruptive radiation therapy technologies have done

    Document Archiving, Replication and Migration Container for Mobile Web Users

    With the increasing use of mobile workstations for a wide variety of tasks and associated information needs, and with many variations of available networks, access to data becomes a prime consideration. This paper discusses issues of workstation mobility and proposes a solution wherein the data structures are accessed in an encapsulated form - through the Portable File System (PFS) wrapper. The paper discusses an implementation of the Portable File System, highlighting the architecture and commenting upon performance of an experimental system. Although investigations have been focused upon mobile access of WWW documents, this technique could be applied to any mobile data access situation.Comment: 5 page

    Charged Current Universality in the MSSM

    Get PDF
    We compute the complete one-loop contributions to low-energy charged current weak interaction observables in the Minimal Supersymmetric Standard Model (MSSM). We obtain the constraints on the MSSM parameter space which arise when precision low-energy charged current data are analyzed in tandem with measurements of the muon anomaly. While the data allow the presence of at least one light neutralino, they also imply a pattern of mass splittings among first and second generation sleptons and squarks which contradict predictions of widely used models for supersymmetry breaking mediation.Comment: 4 pages, 2 figure

    Higgs Boson Decays to Neutralinos in Low-Scale Gauge Mediation

    Full text link
    We study the decays of a standard model-like MSSM Higgs boson to pairs of neutralinos, each of which subsequently decays promptly to a photon and a gravitino. Such decays can arise in supersymmetric scenarios where supersymmetry breaking is mediated to us by gauge interactions with a relatively light gauge messenger sector (M_{mess} < 100 TeV). This process gives rise to a collider signal consisting of a pair of photons and missing energy. In the present work we investigate the bounds on this scenario within the minimal supersymmetric standard model from existing collider data. We also study the prospects for discovering the Higgs boson through this decay mode with upcoming data from the Tevatron and the LHC.Comment: 18 pages, 5 figures, added references and discussion of neutralino couplings, same as journal versio
