How have suicide rates responded to the marked increase in unemployment spurred by Great Recession? Our paper puts this issue into a wider perspective assessing (1) whether unemployment-suicide link is modified degree of protection, and (2) effect on present crisis differs from effects previous economic downturns.We analysed using time-series data for 30 countries spanning period 1960-2012. Separate fixed-effects models were estimated each five welfare state regimes with different levels...

Significance One of the most fundamental predictions almost any model crime is that individual time preferences matter. However, empirical evidence on this basic property essentially nonexistent. We empirically investigate whether discounting measured at age 13 predicts subsequent criminal involvement up to 31. show significantly activity and high discount rates predict more strongly extensive margin rather than for total crime. The link much stronger among males with low intelligence.

Experimental results are presented using quantum-barrier-varactor (QBV) diodes in harmonic multipliers. Output powers and tripler conversion efficiencies of more than 2 mW 5%, respectively, were achieved between 210 280 GHz. In a crude experiment, an efficiency 0.2% for the fifth was measured at 310 The values QBV diode as comparable to state-of-the-art Schottky-varactor triplers. experimental agree well with theoretical calculations.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML"...

We estimate the causal effects of parental incarceration on children’s short- and long-run outcomes using administrative data from Sweden. Our empirical strategy exploits exogenous variation in random assignment criminal defendants to judges with different tendencies. find that a parent childhood leads significant increase teen crime decreases educational attainment adult employment.

Theoretical work on single barrier varactor (SBV) diodes indicates that the efficiency of a tripler with SBV diode has maximum for considerably smaller capacitance variation than previously thought. based GaAs, InGaAs and InAs have been fabricated their DC properties tested. Detailed modeling carrier transport device is carried out in two steps. First, semiconductor equations are solved simultaneously, using finite difference scheme one dimension. Second, calculated I-V C-V characteristics...

This paper investigates the relationship between time preferences and lifetime social economic behavior. We use a Swedish longitudinal dataset that links information from large survey on children's at age 13 to administrative registers spanning over five decades. Our results indicate substantial adverse high discount rates school performance, health, labor supply, income. Males ability children gain significantly more being future-oriented.

Abstract Quantum‐well diodes have been used for generating power at millimeter and submillimeter waves, both in negative resistance oscillators multipliers. In this article, we will first discuss the versus frequency maximum of oscillation “ordinary” quantum‐well oscillators. Possible methods improving output be suggested. diode multipliers also discussed. Realizing importance nonlinear capacitance quantumwell multiplier efficiency, investigated a quantum‐barrier applications.
