We measure the impact of measurement error in labor-supply elasticities estimated over recalled usual work hours, as is ubiquitous in the literature. We employ data on hours of work in diaries collected by the American Time Use Survey, 2003-15, along with the same respondents’ recalled usual work hours. Estimates using the latter yield elasticities that are positively biased. We argue that this...

Introduction With the general support of the CIC members, the University of Michigan and the University of Illinois at Urbana-Champaign have been working together to share ideas and accomplishments of their institutional repositories (IR) – Deep Blue and IDEALS. Their collaborative goals include creating interoperable systems and learning from one another’s mistakes and successes. They hope lat...

I owe Prof. Volz a deep sense of gratitude for his valuable, generous guidance during my PhD and also during the initial phases of my career. He has this amazing willingness to help me in all aspects of my career. I have always valued his advice based on his deep insight fully knowing that at all times he has my best interests in mind at all times. He has always been open to my ideas and suppor...

At the beginning of 2008, I visited a watershed located in Karkinatam village in the state of Karnataka, South India. There, crops are intensively irrigated using groundwater. The water table has been depleted from 5 m-depth to 50 m-depth in a large part of the area. Now, 42 % of a total of 158 water wells in the watershed are dry. Speaking with the farmers, I have been amazed to learn that the...

With easy access to and exponential growth of online resources in the last decade, the Web has become the primary information source to middle school students for their school work. Yet, prior research has shown that students have difficulty evaluating, reading, and taking notes from online resources. This study analyzed the effectiveness of a digital notepad, which used prompts to scaffold mid...

Deep surveys at 850μm from Mauna Kea using the SCUBA camera on the JCMT appear to have discovered a substantial population of ultraluminous infrared galaxies (ULIGs: Lir > 10 L⊙) 3 at high redshift (z ∼ 1−4). The cumulative space density of these sources (∼ 10 deg with S850 > 1mJy) is sufficient to account for nearly all of the extragalactic background light at submillimeter wavelengths. Curren...

Blue and white top-emitting organic light-emitting devices OLEDs with cavity effect have been fabricated. TBADN:3%DSAPh and Alq3:DCJTB/TBADN:TBPe/Alq3:C545 were used as emitting materials of microcavity OLEDs. On a patterned glass substrate, silver was deposited as reflective anode, and copper phthalocyanine (CuPc) layer as HIL and 4’-bis[N-(1-Naphthyl)N-phenyl-amino]biphenyl (NPB) layer as HTL...

Cellular blue nevus is an uncommon pigmented tumor in the conjunctiva, where it generally appears as a deep, circumscribed, pigmented conjunctival mass. We report a case of conjunctival blue nevus that clinically resembled primary acquired melanosis and gave rise to conjunctival melanoma. A 41-year-old man developed a diffuse pigmented mass in the inferior fornix of his left eye. Over a 20-year...

! Gilbert Baker designed the rainbow flag for the 1978 San Francisco's Gay Freedom Celebration. In the original eight-color version, pink stood for sexuality, red for life, orange for healing, yellow for the sun, green for nature, turquoise for art, indigo for harmony and violet for the soul.! First unveiled on 12/5/98 the bisexual pride flag was designed by Michael Page. This rectangular flag ...

Three new blue-emitting compounds of 5P-VA, 5P-VTPA, and 5P-DVTPA for organic light-emitting diode (OLED) based on hexaphenylbenzene moiety were demonstrated. Physical properties by the change of the substitution groups of the synthesized materials were systematically examined. Photoluminescence spectrum of the synthesized materials showed maximum emitting wavelengths of about 400 to 447 nm in ...
