Book review: the housing debate by Stuart Lowe

The UK’s housing shortage and the negative effects this brings for renters, mortgage-payers and those in social housing is rarely out of the news, making Stuart Lowe’s account of the current situation a relevant introduction to the topic. Kerwin Datu would have valued more answers from Lowe on where we can go next, however

The Story of Safe2Tell

This publication highlights the Safe2Tell program, including the far-reaching impact of providing students in all Colorado schools an increased ability to both prevent and report violence by making anonymous calls to 1-877-542-SAFE. It also illustrates through stories and interviews the value of Safe2Tell among families and communities, necessary steps and resources to implement the program, and the hotline's long-term sustainability achieved through legislation

Is Retirement Depressing?: Labor Force Inactivity and Psychological Well-Being in Later Life

This paper assesses how retirement - defined as permanent labor force non-participation in a man's mature years - affects psychological welfare. The raw correlation between retirement and well-being is negative. But this does not imply causation. In particular, people with idiosyncratically low well-being, or people facing transitory shocks which adversely affect well-being might disproportionately select into retirement. Discontinuous retirement incentives in the Social Security System, and changes in laws affecting mandatory retirement and Social Security benefits allows the exogenous effect of retirement on happiness to be estimated. The paper finds that the direct effect of retirement on well-being is positive once the fact that retirement and well being are simultaneously determined is accounted for.

Integrated structure vacuum tube

High efficiency, multi-dimensional thin film vacuum tubes suitable for use in high temperature, high radiation environments are described. The tubes are fabricated by placing thin film electrode members in selected arrays on facing interior wall surfaces of an alumina substrate envelope. Cathode members are formed using thin films of triple carbonate. The photoresist used in photolithography aids in activation of the cathodes by carbonizing and reacting with the reduced carbonates when heated in vacuum during forming. The finely powdered triple carbonate is mixed with the photoresist used to delineate the cathode locations in the conventional solid state photolithographic manner. Anode and grid members are formed using thin films of refractory metal. Electron flow in the tubes is between grid elements from cathode to anode as in a conventional three-dimensional tube

Integrated structure vacuum tube: A Concept

Cathode emission is made to occur by heating entire structure to 600 C, and positive potential is applied to anode with negative potential on grids. Electron flow takes place from ring to circular anode through electric field produced by grids

Active rc filter permits easy trade-off of amplifier gain and sensitivity to gain

Passive RC network was designed with zeros of transmission in the right half of the complex frequency plane in the feedback loop of a simple negative-gain amplifier. The proper positioning provides any desired trade-off between amplifier gain and sensitivity to amplifier gain

Constant-amplitude RC oscillator

Sinusoidal oscillator has a frequency determined by resistance-capacitance /RC/ values of two charge control devices and a constant-amplitude voltage independent of frequency and RC values. RC elements provide either voltage-control, resistance-control, or capacitance-control of the frequency
