Federal Programs Available to Unemployed Workers

[Excerpt] Four groups of federal programs target unemployed workers: income support, health care assistance, job search assistance, and training. Unemployed workers and their families may experience substantial income loss and, as a result, may qualify for a number of other federal programs that determine eligibility based on income (e.g., the Earned Income Tax Credit, Temporary Assistance for Needy Families, or Medicaid). This report presents information on federal programs targeted to unemployed workers specifically, but does not attempt to discuss means-tested programs. A variety of benefits may be available to unemployed workers to provide them with income support during a period of unemployment. When eligible workers lose their jobs, the Unemployment Compensation (UC) program may provide income support through the payment of UC benefits (often referred to as Unemployment Insurance, or UI, benefits). Certain groups of workers who lose their jobs on account of international competition may qualify for additional or supplemental income support through Trade Adjustment Act (TAA) programs. If an unemployed worker is not eligible to receive UC benefits and the worker’s unemployment may be directly attributed to a declared major disaster, a worker may be eligible to receive Disaster Unemployment Assistance (DUA) benefits. Two federal laws may aid unemployed workers in the purchase of health insurance. The first, the Consolidated Omnibus Budget Reconciliation Act of 1985 (COBRA), allows unemployed workers in certain circumstances to purchase continued health insurance coverage. The second, the Health Care Tax Credit (HCTC), allows certain TAA and Alternative TAA (for older workers) participants to receive an advanceable and refundable tax credit for purchasing health insurance. Federal support for Americans seeking assistance to obtain, retain, or change employment is undertaken by a national system of local One-Stop Career Centers (One-Stops) that were established by the Workforce Investment Act of 1998 (WIA, P.L. 105-220). A variety of services and partner programs — notably including UC and TAA — are located within or linked to One-Stops, which primarily provide job search assistance, career counseling, labor market information, and other employment services. Core labor exchange services (matching job seekers and employers) are provided by the U.S. Employment Service, which was first established by the Wagner-Peyser Act of 1933 and most recently amended under Title III of WIA. In addition to ES, Title I of WIA authorizes resources for similar core and intensive employment services for youth, adults, dislocated workers, and targeted populations. WIA Title I is also the nation’s central job training legislation, providing funds for traditional, on-the-job, customized, and other forms of training to individuals unable to obtain or retain employment through other services. This report will be updated as new legislation warrants

Analysis and optimisation of semiconductor reflective modulators for optical networks

Reflective modulators based on the combination of an electroabsorption modulator (EAM) and semiconductor optical amplifier (SOA) are attractive devices for applications in long reach carrier distributed passive optical networks (PONs) due to the gain provided by the SOA and the high speed and low chirp modulation of the EAM. Integrated R-EAM-SOAs have experimentally shown two unexpected and unintuitive characteristics which are not observed in a single pass transmission SOA: the clamping of the output power of the device around a maximum value and low patterning distortion despite the SOA being in a regime of gain saturation. In this thesis a detailed analysis is carried out using both experimental measurements and modelling in order to understand these phenomena. For the first time it is shown that both the internal loss between SOA and R-EAM and the SOA gain play an integral role in the behaviour of gain saturated R-EAM-SOAs. Internal loss and SOA gain are also optimised for use in a carrier distributed PONs in order to access both the positive effect of output power clamping, and hence upstream dynamic range reduction, combined with low patterning operation of the SOA Reflective concepts are also gaining interest for metro transport networks and short reach, high bit rate, inter-datacentre links. Moving the optical carrier generation away from the transmitter also has potential advantages for these applications as it avoids the need for cooled photonics being placed directly on hot router line-cards. A detailed analysis is carried out in this thesis on a novel colourless reflective duobinary modulator, which would enable wavelength flexibility in a power-efficient reflective metro node

Current Status and Future Prospects of Marine Natural Products (MNPs) as Antimicrobials

peer-reviewedThe marine environment is a rich source of chemically diverse, biologically active natural products, and serves as an invaluable resource in the ongoing search for novel antimicrobial compounds. Recent advances in extraction and isolation techniques, and in state-of-the-art technologies involved in organic synthesis and chemical structure elucidation, have accelerated the numbers of antimicrobial molecules originating from the ocean moving into clinical trials. The chemical diversity associated with these marine-derived molecules is immense, varying from simple linear peptides and fatty acids to complex alkaloids, terpenes and polyketides, etc. Such an array of structurally distinct molecules performs functionally diverse biological activities against many pathogenic bacteria and fungi, making marine-derived natural products valuable commodities, particularly in the current age of antimicrobial resistance. In this review, we have highlighted several marine-derived natural products (and their synthetic derivatives), which have gained recognition as effective antimicrobial agents over the past five years (2012–2017). These natural products have been categorized based on their chemical structures and the structure-activity mediated relationships of some of these bioactive molecules have been discussed. Finally, we have provided an insight into how genome mining efforts are likely to expedite the discovery of novel antimicrobial compounds

The hydrology of an ephemerally flooded doline: Pwll-y-Felin, South Wales, UK

The first annual hydrograph from an ephemerally-flooded doline in the UK is described. Flood duration and volume were characterised by combining water-level data with a detailed topographic survey. Rapid surface runoff of Na–SO4-type water is derived from a localized topographic catchment. The inflow stream produced a ‘flashy’ hydrograph with maximum flood depths reaching 7m when the doline can contain 7,383 m3 of water. Flooding occurred over 161 of the 365 day study period, with an average flood depth of 2.4m. Stage dependent drainage properties suggested that water loss is greater when the flood depth is >3m, indicating that there may be additional drainage conduits at higher levels within the doline. A conservative estimate of 138 ML year is provided for net loss of water to the underlying aquifer. The vegetation shows some zonation potentially related to flood duration, with higher diversity in the marginal zone subject to the greatest fluctuation in water levels. The classification of Pwll-y-Felin and other small ephemeral karstic water bodies should be considered not only as geological landforms but as small karstic dependant wetlands. Under-recording of small, isolated temporary water bodies is of concern to international conservation bodies. The methodology presented can help to characterize the hydrology of ephemerally flooded dolines and could be used better to understand karst dependent habitats, recharge in karst aquifers, water budget calculations and to improve management and regulation in karst aquifers

Point-to-point overlay of a 100Gb/s DP-QPSK channel in LR-PONs for urban and rural areas

The continuing growth in information demand from fixed and mobile end-users, coupled with the need to deliver this content in an economically viable manner, is driving new innovations in access networks. In particular, it is becoming increasingly important to find new ways to enable the coexistence of heterogeneous services types which may require different signal modulation formats over the same fiber infrastructure. For example, the same physical layer can potentially be used to deliver shared 10Gb/s services to residential customers, dedicated point-to-point (P2P) 100Gb/s services to business customers, and wireless fronthaul, in a highly cost-effective manner. In this converged scenario, the performance of phase modulated signals can be heavily affected by nonlinear crosstalk from co-propagating on-off-keying (OOK) channels. In this paper, the overlay of a 100G P2P dual-polarization quadrature phase-shift keying (DP-QPSK) channel in a long-reach passive optical network (LR-PON) in the presence of co-propagating 10Gb/s OOK neighboring channels is studied for two different PON topologies. The first LR-PON topology is particularly suited for densely populated areas while the second is aimed at rural, sparsely populated areas. The experimental results indicate that with an emulated load of 40 channels the urban architecture can support up to 100km span and 512 users, while the rural architecture can support up to 120km span and 1024 users. Finally, a system model is developed to predict the system performance and system margins for configurations different from the experimental setups and to carry out design optimization that could in principle lead to even more efficient and robust schemes

HPLC-ESI-MS/MS characterisation of metabolites produced by Pseudovibrio sp. W64, a marine sponge-derived bacterium isolated from Irish waters

Rationale: In recent years, metabolites produced by Pseudovibrio species have gained scientific attention due to their potent antimicrobial activity. Recently we also have assessed antibacterial activities of Pseudovibrio sp. W64 isolates against Staphylococcus aureus, where only the dominant tropodithietic acid (TDA) was identified. However characterisation of other metabolites is necessary as these metabolites may also serve as potent antimicrobial agents. Methods: LC-MS/MS, aided by accurate mass measurements, was employed to screen and characterise a range of metabolites produced by Pseudovibrio sp. W64 via assessment of ethyl acetate fractions generated from bacterial cultures. Results: Thirteen metabolites unique to the bacterial culture were detected and their chemical structures were assigned by tandem mass spectrometry and accurate mass measurement. Among the thirteen metabolites, a methyl ester of TDA, a number of cholic acid derivatives, and amino diols and triols were characterised. Conclusions: Pseudovibrio sp. W64 produces methylated TDA in addition to TDA, and metabolises lipids and amino acids in the cell-culture medium. To the best of our knowledge, this is the first report of methylated TDA, cholic acid and its various analogs, and sphinganine being detected in this Pseudovibrio strain. The data generated may help to better understand the biochemical processes and metabolism of bacterial strains towards discovery of antimicrobial agents from marine sources

SDN enabled dynamically reconfigurable high capacity optical access architecture for converged services

Dynamically reconfigurable time-division multiplexing (TDM) dense wavelength division multiplexing (DWDM) long-reach passive optical networks (PONs) can support the reduction of nodes and network interfaces by enabling a fully meshed flat optical core. In this paper we demonstrate the flexibility of the TDM-DWDM PON architecture, which can enable the convergence of multiple service types on a single physical layer. Heterogeneous services and modulation formats, i.e. residential 10G PON channels, business 100G dedicated channel and wireless fronthaul, are demonstrated co-existing on the same long reach TDM-DWDM PON system, with up to 100km reach, 512 users and emulated system load of 40 channels, employing amplifier nodes with either erbium doped fiber amplifiers (EDFAs) or semiconductor optical amplifiers (SOAs). For the first time end-to-end software defined networking (SDN) management of the access and core network elements is also implemented and integrated with the PON physical layer in order to demonstrate two service use cases: a fast protection mechanism with end-to-end service restoration in the case of a primary link failure; and dynamic wavelength allocation (DWA) in response to an increased traffic demand
