Alex Haley, A History of the Negro in America, 1968
No full textAlex Haley was an American author and writer of several critically acclaimed novels and biographies including Malcolm X, and Roots: The Saga of an American Family. A fervent scholar of African American history, Haley here gives a presentation centered around his genealogical research in preparation for writing Roots. Referring to African Americans as “the only unwilling immigrants” to the United States, Haley traces his own roots back to the slave ship that brought his ancestors to the New World, detailing European first impressions of African culture, and vice versa.https://commons.emich.edu/lectures_presentations/1002/thumbnail.jp

Infrastructure bottlenecks, private provision, and industrial productivity : a study of Indonesian and Thai cities
No full textThis research project followed an earlier similar project on Nigeria, applying the same methods. A sample of manufacturers was surveyed to document their responses to infrastructure deficiencies in electricity, water, transport, telecommunications, and waste disposal. They found the manufacturers undertook significant expenditures to offset deficiencies in publicly provided infrastructure services, and that changing public policy toward privately supplied infrastructure and changing the pricing of public infrastructure could yield significant savings in social costs. Thailand and Indonesia have made significant strides in following the policies for private sector participation in infrastructure provision. Nigeria, where public infrastructure monopolies still dominate, lags behind, yet stands to benefit most from such policy reform. Government policy toward the industrial organization and pricing of infrastructure sectors can significantly help a developing economy realize the benefits of private sector participation in the provision of infrastructure services.Banks&Banking Reform,Decentralization,Public Sector Economics&Finance,Environmental Economics&Policies,Municipal Financial Management,Banks&Banking Reform,Municipal Financial Management,Urban Services to the Poor,Urban Services to the Poor,Public Sector Economics&Finance
The Impact of Functional, Fluid, and Crystallized Cognition on Gainful Employment of People With Neurological Disorders: A Multisite Cohort Study
No full textAbstract
Date Presented 3/31/2017
Functional cognition assessed by occupational therapy should complement neuropsychological testing of fluid and crystallized cognition if our goal is to optimize participation in work activities. Evidence suggests functional and fluid cognition as potential targets for intervention.

Efficient picosecond x-ray pulse generation from plasmas in the radiation dominated regime
No full textThe efficient conversion of optical laser light into bright ultrafast x-ray pulses in laser created plasmas is of high interest for dense plasma physics studies, material science, and other fields. However, the rapid hydrodynamic expansion that cools hot plasmas has limited the x-ray conversion efficiency (CE) to 1% or less. Here we demonstrate more than one order of magnitude increase in picosecond x-ray CE by tailoring near solid density plasmas to achieve a large radiative to hydrodynamic energy loss rate ratio, leading into a radiation loss dominated plasma regime. A record 20% CE into ℎ>1 keVhν>1 keV photons was measured in arrays of large aspect ratio Au nanowires heated to keV temperatures with ultrahigh contrast femtosecond laser pulses of relativistic intensity. The potential of these bright ultrafast x-ray point sources for table-top imaging is illustrated with single shot flash radiographs obtained using low laser pulse energy. These results will enable the deployment of brighter laser driven x-ray sources at both compact and large laser facilities.Fil: Hollinger, Reed.

A social-cognitive model of trait and state levels of gratitude.
No full textThree studies tested a new model of gratitude, which specified the generative mechanisms linking individual differences (trait gratitude) and objective situations with the amount of gratitude people experience after receiving aid (state gratitude). In Study 1, all participants (N = 253) read identical vignettes describing a situation in which they received help. People higher in trait gratitude made more positive beneficial appraisals (seeing the help as more valuable, more costly to provide, and more altruistically intended), which fully mediated the relationship between trait and state levels of gratitude. Study 2 (N = 113) replicated the findings using a daily process study in which participants reported on real events each day for up to14 days. In Study 3, participants (N = 200) read vignettes experimentally manipulating objective situations to be either high or low in benefit. Benefit appraisals were shown to have a causal effect on state gratitude and to mediate the relationship between different prosocial situations and state gratitude. The 3 studies demonstrate the critical role of benefit appraisals in linking state gratitude with trait gratitude and the objective situation
Decoupled textures for broadband absorption enhancement beyond Lambertian light trapping limit in thin-film silicon-based solar cells
No full textWe present a modelling study of thin silicon based solar cells endowed with periodic and decoupled front/back textures. After careful optimization, the proposed device models exhibit absorption beyond the Lambertian light trapping limit for a wide range of light angles of incidence. The advanced light management scheme is applied to (nano)crystalline silicon solar cells, where the benefits of texturing the absorber rather than the supporting layers is clear and to barium (di)silicide solar cells, which could achieve an implied photocurrent densityof41.1 mA/cm2 for a thickness of only 2 \mum.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Photovoltaic Materials and DevicesElectrical Sustainable Energ
