How do area-level socioeconomic status and gender norms affect partner violence against women? Evidence from Tanzania.

: To explore how area-level socioeconomic status and gender-related norms influence partner violence against women in Tanzania. : We analysed data from the 2010 Tanzania Demographic and Health Survey and used multilevel logistic regression to estimate individual and community-level effects on women's risk of current partner violence. : Prevalence of current partner violence was 36.1 %; however, variation in prevalence exists across communities. Twenty-nine percent of the variation in the logodds of partner violence is due to community-level influences. When adjusting for individual-level characteristics, this variation falls to 10 % and falls further to 8 % when adjusting for additional community-level factors. Higher levels of women's acceptance towards wife beating, male unemployment, and years of schooling among men were associated with higher risk of partner violence; however, higher levels of women in paid work were associated with lower risk. : Area-level poverty and inequitable gender norms were associated with higher risk of partner violence. Empowerment strategies along with addressing social attitudes are likely to achieve reductions in rates of partner violence against women in Tanzania and in other similar low-income country settings.<br/

Sexual Harassment: A Doctrinal Examination of the Law, An Empirical Examination of Employer Liability, and A Question About NDAs— Because Complex Problems Do Not Have Simple Solutions

The #MeToo movement casts critical light on the pervasive nature of sexual harassment, particularly in the employment context, and continues to motivate a number of initiatives that address important social and workplace ills. The problems this movement has uncovered, however, run much deeper and likely exceed the scope and capacity of many of the proposed “fixes” it has inspired. Worse still, however, is that some of the proposed fixes may prove counterproductive. This Article examines the history and development of the relevant employment laws, empirically assesses judicial holdings on the employers’ affirmative defense to liability, and argues that many employees may be better off with a nondisclosure agreement (NDA) in many instances. Our conclusion sketches out the basic contours of an alternative legal standard, a new affirmative defense, and related policy initiatives that call into question the common perception that privacy benefits employers and not employees

Gravitational Wave Memory of Gamma-Ray Burst Jets

Gamma-Ray Bursts (GRBs) are now considered as relativistic jets. We analyze the gravitational waves from the acceleration stage of the GRB jets. We show that (i) the point mass approximation is not appropriate if the opening half-angle of the jet is larger than the inverse of the Lorentz factor of the jet, (ii) the gravitational waveform has many step function like jumps, and (iii) the practical DECIGO and BBO may detect such an event if the GRBs occur in Local group of galaxy. We found that the light curve of GRBs and the gravitational waveform are anti-correlated so that the detection of the gravitational wave is indispensable to determine the structure of GRB jets.Comment: Revtex4, 10 pages, 6 figures, Fig.2 and Fig.3 replaced, minor changes to text in Sec.I and Sec.V, typos corrected, some reference added, Version to be published in PR

The N=8 Supergravity Hamiltonian as a Quadratic Form

We conjecture that the light-cone Hamiltonian of N=8 Supergravity can be expressed as a quadratic form. We explain why this rewriting is unique to maximally supersymmetric theories. The N=8 quartic interaction vertex is constructed and used to verify that this conjecture holds to second order in the coupling constant

X-ray Spectral Diagnostics of Gamma-Ray Burst Environments

Recently, the detection of discrete features in the X-ray afterglow spectra of GRB970508 and GRB970828 was reported. The most natural interpretation of these features is that they are redshifted Fe K emission complexes. The identification of the line emission mechanism has drastic implications for the inferred mass of radiating material, end hence the nature of the burst site. X-ray spectroscopy provides a direct observational constraint on these properties of gamma-ray bursters. We briefly discuss how these constraints arise, in the context of an application to the spectrum of GRB970508.Comment: 11 pages, 2 figures, accepted for publication in ApJ Letter
