"Did the Clinton Rising Tide Raise All Boats? Job Opportunity for the Less Skilled"

During the recent robust expansion only 700,000 of the almost 12 million jobs created went to the half of the population that does not have at least some college education. Even though the number of officially unemployed fell to less than 4 million in the 25 and over age group, there remain in that age group over 26 million potentially employable workers—the combined number of those who are actively seeking work (and are counted as officially unemployed) and those who are currently out of the labor force but would be willing to participate. Since expansion has not proven sufficient to remedy this intolerably high level of wasted human resources, well-targeted, active labor market policies are required. One such policy is a job opportunity program that "hires off the bottom," providing minimum-wage jobs for all those who are ready, willing, and able to work. The program would create a buffer stock of labor from which employers could hire during upturns instead of bidding up the wages of the already employed and thus would offer both full employment and price stability.

"Demand Constraints and Economic Growth"

In recent years the U.S. has seemed to achieve the best of all possible worlds: robust economic growth, very low unemployment, and low inflation. Many attribute this performance to fewer supply side constraints, as the U.S. has moved away from stifling regulations and other impediments to trade. When compared with the very high unemployment rates suffered in European countries, our lower unemployment rates appear to be due to freer labor markets and to a less generous social safety net that saps private initiative. In this paper we show that although it is true the U.S. has enjoyed a higher employment rate than all of our major competitors, we lag behind all other major countries in per capita GDP growth since 1970. The reason is our dismal rate of productivity growth. We show that when one decomposes per capita GDP growth into its component parts--growth of employment rates and growth of output per employee--the U.S. experience is quite different from that of the other countries. In some sense, countries "choose" high employment paths or low employment paths, but regardless of that choice, economic growth does not appear to be much affected. We argue that this is because countries have not faced significant supply constraints; rather, per capita GDP growth has been largely demand constrained. For this reason policies aimed at removing supply constraints do not lead to more rapid economic growth. The conclusion is that, if one is to trying to increase growth rates, Keynesian "demand side" policies are preferable to "supply side" policies.

Down and out in the United States: An inside look at the out of the labor force population

Despite a long period of strong economic growth, more than 28 million working-age persons were categorized by the Bureau of Labor Statistics as out of the labor force in 1998. A small portion of this population will move into the labor force, but the majority will remain without work. This brief examines the demographics of the out-of-the-labor-force population, their reasons for not working, the likelihood that they will move into the labor force, and the adverse effects on them of prolonged joblessness. Current labor market policies, and especially welfare reform measures, have proved ineffective for the hard-core jobless because the policies are predicated on the mistaken notion that the private labor market is dynamic and flexible enough to accommodate anyone who wants to work. A public employment program would complement the operation of the private market, providing those who are able and willing with income, a sense of worth, the opportunity to make a social and economic contribution, and preparation for entry into the labor force

Visual Representation in the Wild: How Rhesus Monkeys Parse Objects

Visual object representation was studied in free-ranging rhesus monkeys. To facilitate comparison with humans, and to provide a new tool for neurophysiologists, we used a looking time procedure originally developed for studies of human infants. Monkeys' looking times were measured to displays with one or two distinct objects, separated or together, stationary or moving. Results indicate that rhesus monkeys used featural information to parse the displays into distinct objects, and they found events in which distinct objects moved together more novel or unnatural than events in which distinct objects moved separately. These findings show both common-alities and contrasts with those obtained from human infants. We discuss their implications for the development and neural mechanisms of higher-level vision.Psycholog

Design for an 8 Meter Monolithic UV/OIR Space Telescope

ATLAST-8 is an 8-meter monolithic UV/optical/NIR space observatory to be placed in orbit at Sun-Earth L2 by NASA's planned Ares V cargo launch vehicle. The ATLAST-8 will yield fundamental astronomical breakthroughs. The mission concept utilizes two enabling technologies: planned Ares-V launch vehicle (scheduled for 2019) and autonomous rendezvous and docking (AR&D). The unprecedented Ares-V payload and mass capacity enables the use of a massive, monolithic, thin-meniscus primary mirror - similar to a VLT or Subaru. Furthermore, it enables simple robust design rules to mitigate cost, schedule and performance risk. AR&D enables on-orbit servicing, extending mission life and enhancing science return

Electrical and network neuronal properties are preferentially disrupted in dorsal, but not ventral, medial entorhinal cortex in a mouse model of Tauopathy

The entorhinal cortex (EC) is one of the first areas to be disrupted in neurodegenerative diseases such as Alzheimer's disease and frontotemporal dementia. The responsiveness of individual neurons to electrical and environmental stimuli varies along the dorsal-ventral axis of the medial EC (mEC) in a manner that suggests this topographical organization plays a key role in neural encoding of geometric space. We examined the cellular properties of layer II mEC stellate neurons (mEC-SCs) in rTg4510 mice, a rodent model of neurodegeneration. Dorsoventral gradients in certain intrinsic membrane properties, such as membrane capacitance and afterhyperpolarizations, were flattened in rTg4510 mEC-SCs, while other cellular gradients [e.g., input resistance (Ri), action potential properties] remained intact. Specifically, the intrinsic properties of rTg4510 mEC-SCs in dorsal aspects of the mEC were preferentially affected, such that action potential firing patterns in dorsal mEC-SCs were altered, while those in ventral mEC-SCs were unaffected. We also found that neuronal oscillations in the gamma frequency band (30-80 Hz) were preferentially disrupted in the dorsal mEC of rTg4510 slices, while those in ventral regions were comparatively preserved. These alterations corresponded to a flattened dorsoventral gradient in theta-gamma cross-frequency coupling of local field potentials recorded from the mEC of freely moving rTg4510 mice. These differences were not paralleled by changes to the dorsoventral gradient in parvalbumin staining or neurodegeneration. We propose that the selective disruption to dorsal mECs, and the resultant flattening of certain dorsoventral gradients, may contribute to disturbances in spatial information processing observed in this model of dementia. SIGNIFICANCE STATEMENT: The medial entorhinal cortex (mEC) plays a key role in spatial memory and is one of the first areas to express the pathological features of dementia. Neurons of the mEC are anatomically arranged to express functional dorsoventral gradients in a variety of neuronal properties, including grid cell firing field spacing, which is thought to encode geometric scale. We have investigated the effects of tau pathology on functional dorsoventral gradients in the mEC. Using electrophysiological approaches, we have shown that, in a transgenic mouse model of dementia, the functional properties of the dorsal mEC are preferentially disrupted, resulting in a flattening of some dorsoventral gradients. Our data suggest that neural signals arising in the mEC will have a reduced spatial content in dementia

Novel approaches to the construction of miniaturized analytical instrumentation

This paper focuses on the design, construction, preliminary testing, and potential applications of three forms of miniaturized analytical instrumentation. The first is an optical fiber instrument for monitoring pH and other cations in aqueous solutions. The instrument couples chemically selective indicators that were immobilized at porous polymeric films with a hardware package that provides the excitation light source, required optical components, and detection and data processing hardware. The second is a new form of a piezoelectric mass sensor. The sensor was fabricated by the deposition of a thin (5.5 micron) film of piezoelectric aluminum nitride (AIN). The completed deposition process yields a thin film resonator (TFR) that is shaped as a 400 micron square and supports a standing bulk acoustic wave in a longitudinal mode at frequencies of approx. 1 GHz. Various deposition and vapor sorption studies indicate that the mass sensitivity of the TFR's rival those of the most sensitive mass sensors currently available, though offering such performance in a markedly smaller device. The third couples a novel form of liquid chromatography with microlithographic miniaturization techniques. The status of the miniaturization effort, the goal of which is to achieve chip-scale separations, is briefly discussed
