The effect of changes in the skill premium on college degree attainment and the choice of major
We study the impact of financial incentives on higher education decisions and the choice of major. We rely on a reform whereby Israeli kibbutzim shifted from their traditional policy of equal sharing to productivity-based wages, using for identification the staggered implementation of this reform.
In this setting of very low initial returns to education, we find that the dramatic increase in the rate of return and its sharp variation across fields of study led to a large increase in the probability of receiving a Bachelor’s degree, especially in STEM fields of study that are expected to yield higher financial returns. men and women
Tunable Touch Sensor and Combined Sensing Platform: Toward Nanoparticle-based Electronic Skin
In
this paper, we present touch (or pressure) flexible sensors based
on monolayer-capped nanoparticles (MCNPs) that are potentially inexpensive,
could allow low-voltage operation, and could provide a platform for
multifunctional applications. We show that modifying the mechanical
and geometrical properties of the flexible substrates, on which the
MCNP films are deposited, allows measuring a large span of loads ranging
between tens of mg to tens of grams. All flexible sensors exhibited
repeatable responses even after a large number of bending cycles.
In addition, we show that modified platforms of those touch (or pressure)
sensors allow precise detection and monitoring of environmental temperature
and humidity. Relying on their superior characteristics, we were able
to build an MCNP-based prototype allowing simultaneous detection and
monitoring of multiple environmental parameters of touch (or pressure),
humidity, and temperature. The excellent temperature (resolution higher
than 1 °C and average error of ∼5%) and relative humidity
(resolution higher than 1% RH and average error of ∼9%) sensitivities
and the possibility to integrate those sensing abilities makes the
suggested platform interesting for potentially inexpensive and low-voltage
multifunctional <i>electronic-skin</i> applications
