    How Policy Variables Influence the Timing of Social Security Disability Insurance Applications - Policy Brief

    Get PDF
    While the onset of a health based work limitation will affect a worker’s ability to remain on the job, it does not necessarily result in a swift and certain job exit and transition onto the disability rolls. The decision to leave the workforce and apply for SSDI benefits can be influenced both positively and negatively by policy variables. These two policy thrusts—SSDI transfers to replace lost earnings and accommodation to increase duration on the job—can send mixed signals to workers who experience the onset of a disability. Hence, understanding how such policies influence behavior for those who experience a disability is critical in developing policies that fully integrate people with disabilities into the workforce

    Asia Comes to Main Street and May Learn to Speak Spanish: Globalization in a Poor Neighborhood in Worcester

    Get PDF
    This paper considers how and why an Asian enclave of small businesses has appeared in a poor neighborhood characterized by Puerto Rican and other Latino immigration in the post-industrial city of Worcester, Massachusetts. We begin by examining the role of the US in the world system, and argue that the US hegemonic role and specific political economic aspects of global capitalism (ie. deindustrialization) account for some of the migration stream. Next, using socioeconomic and historical data, interviews, and observations, we outline the history of Worcester’s economy and immigration patterns. We demonstrate that the increasing economic inequality leaves few promising employment options for newcomers to Worcester. Drawing on existing literature on immigrant entrepreneurs and ethnic enclaves, we argue that some aspects of the literature appear to shed light on the Vietnamese enterprises which have so visibly appeared (e.g., ethnic niches), while others, (e.g., middle-man minority theory) are not now reflected in local conflict. We conclude by considering the prospects for immigrants to this neighborhood in light of its political economic context

    Neurotransmitter modulation of extracellular H+ fluxes from isolated retinal horizontal cells of the skate

    Self-referencing H+-selective microelectrodes were used to measure extracellular H+ fluxes from horizontal cells isolated from the skate retina. A standing H+ flux was detected from quiescent cells, indicating a higher concentration of free hydrogen ions near the extracellular surface of the cell as compared to the surrounding solution. The standing H+ flux was reduced by removal of extracellular sodium or application of 5-(N-ethyl-N-isopropyl) amiloride (EIPA), suggesting activity of a Na+–H+ exchanger. Glutamate decreased H+ flux, lowering the concentration of free hydrogen ions around the cell. AMPA/kainate receptor agonists mimicked the response, and the AMPA/kainate receptor antagonist 6-cyano-7-nitroquinoxaline-2,3-dione (CNQX) eliminated the effects of glutamate and kainate. Metabotropic glutamate agonists were without effect. Glutamate-induced alterations in H+ flux required extracellular calcium, and were abolished when cells were bathed in an alkaline Ringer solution. Increasing intracellular calcium by photolysis of the caged calcium compound NP-EGTA also altered extracellular H+ flux. Immunocytochemical localization of the plasmalemma Ca2+–H+-ATPase (PMCA pump) revealed intense labelling within the outer plexiform layer and on isolated horizontal cells. Our results suggest that glutamate modulation of H+ flux arises from calcium entry into cells with subsequent activation of the plasmalemma Ca2+–H+-ATPase. These neurotransmitter-induced changes in extracellular pH have the potential to play a modulatory role in synaptic processing in the outer retina. However, our findings argue against the hypothesis that hydrogen ions released by horizontal cells normally act as the inhibitory feedback neurotransmitter onto photoreceptor synaptic terminals to create the surround portion of the centre-surround receptive fields of retinal neuron

    Security Check-In Station

    The major qualifying project is the culmination of lab and courses over four years. The Security Check-In Station is a device which communicates with a central server to give access to guards based on RFID badge verification and voice authentication. The device is designed to have guards check in with the central server showing the patrolled area. By using RFID tags and scanners, and using signal analysis techniques like frequency comparing and signal covariance, the device is able to distinguish guards from imposters

    A Critical Corporate Profile of Li & Fung

    Get PDF
    Behind the prominent Brand names and Retail stores of global supply chains are intermediaries who provide services to large volume buyers. A key feature of the global apparel industry is complex supply chains with many contractors and subcontractors and intense competition among factories – induced by the buyers – to reduce cost and increase speed. Over the past two decades, scholars have noted the dramatic increase of market power of international retail corporations gained at the expense of the fragmentation of centers of production. Enter Li & Fung, a Hong Kong based firm which is the largest sourcing agent in the global apparel business. Li & Fung’s central role in shaping the supply chain of apparel potentially affects the lives of millions of workers in their direct supply chains and the labor markets in which they are such a commanding force. Their strategy of sourcing emphasizes the cutthroat competition among factories that is the source of apparel workers’ conditions. Our analysis also indicates that already an “unseen giant” Li & Fung appears to have decided to move towards higher value-added processes in the supply chain. Understanding the complex implications of Li & Fung’s business strategy for workers’ rights is crucial for securing decent conditions for workers in the apparel industry over the coming years

    An Analysis of Diversity in Freshwater Mussels (Bivalvia: Unionidae) of the Cuyahoga and Rocky River Watersheds (Ohio, USA) Based on the 16S rRNA Gene

    The continued loss of freshwater unionid mussel species in the Great Lakes region, and particularly from Lake Erie, raises the question of how much phylogenetic and genetic variation remain in the watershed. The introduction of molecular markers into population biology offers one reproducible technique for assessing this variation. A fragment of the 16S rRNA gene of mitochondrial DNA has previously been used to infer phylogenetic relationships in the family Unionidae. Therefore, we reanalyzed these published molecular data with the addition of 12 species from the Cuyahoga and Rocky rivers in northeast Ohio. Both rivers drain to Lake Erie. The species assessed were Pyganodon grandis, Lasmigona complanata, Lasmigona compressa, Lampsilis radiata luteola, Fusconaia flava, Potamilus alatus, Strophitus undulatus, and Toxolasma parvus, for which published data were unavailable, and northern specimens of four wide ranging species, Lasmigona costata, Leptodea fragilis, Utterbackia imbecillis, and Quadrula quadrula. The resulting phylogenetic tree remained consistent with the accepted major taxonomic divisions in the Unionidae, and it indicates that these rivers still contain a phylogenetically diverse assemblage. However, the most abundant species all are members of the Anodontinae. Intraspecific variation in these unionid species was low, even where results were compared to published sequences on individuals from distant watersheds. One exception was a unique haplotype of Q. quadrula that differed at more base sites than is generally found for many congeneric species

    In 2009, Clark University was accepted as the university to represent Massachusetts in the National Policy Institute for Family Impact Seminars at the University of Wisconsin – Madison (http://familyimpactseminars.org). Family Impact Seminars are a series of annual seminars, briefing reports, and discussion sessions that provide up-to-date, solution-oriented research on current issues for state legislators, legislative staff, and executive branch personnel. The seminars provide objective, nonpartisan research on current issues and do not lobby for particular policies. Seminar participants discuss policy options and identify common ground where it exists
