An exact solution of Einstein’s field equations for a static spherically symmetric medium with a radially boost invariant energy-momentum tensor is presented. In the limit of an equation of state corresponding to a distribution of radially directed strings there is a 1/r correction to Newton’s force law. At large distances and small accelerations this law coincides with the phenomenological for...

National and international experience now leave no doubt that methods other than enforcement of criminal law are effective in reducing crime and associated harm. In particular, initiatives that are based on routine activity and situational theory, and those that concentrate on addressing specific, well-defined problems, have been demonstrated to have greater impact and to be less costly than "l...

We consider the problem of existence of certain symmetrical solutions of Stokes equation on a three-dimensional manifold M with a general metric possessing symmetry. These solutions correspond to unidirectional flows. We have been able to determine necessary and sufficient conditions for their existence. Symmetric unidirectional flows are fundamental for deducing the so-called Darcy’s law, whic...

We apply the counterterm subtraction technique to calculate the action and other quantities for the Kerr–AdS black hole in five dimensions using two boundary metrics; the Einstein universe and rotating Einstein universe with arbitrary angular velocity. In both cases, the resulting thermodynamic quantities satisfy the first law of thermodynamics. We point out that the reason for the violation of...

PURPOSE To determine the influence of gender on weekly work hours of Ontario dentists. METHODS In 2012, a 52-item survey was sent to a random sample of 3000 Ontario dentists (1500 men and 1500 women) to collect information on personal, professional and sociodemographic characteristics. The resulting data were analyzed using descriptive statistics and linear regression modeling. RESULTS The ...

This study investigates whether rights to parental leave improve pediatric health. Aggregate data are used for 16 European countries over the 1969 through 1994 period. More generous paid leave is found to reduce deaths of infants and young children. The magnitudes of the estimated effects are substantial, especially where a causal effect of leave is most plausible. In particular, there is a muc...

Anesthesiologists perform a broad spectrum of tasks. However, in many countries, there is no legal basis for personnel staffing of physicians in anesthesia. Also, the German diagnosis related groups system for refunding does not deliver such a basis. Thus, in 2006 a new calculation base for the personnel requirement that included an Excel calculation sheet was introduced by the German Board of ...

This paper provides a detailed decomposition analysis of the gender differences in workplace training throughout the working life with a particular focus on parental leave and supervisors using personnel records from a large German firm. Females obtain less training during the early career, and more at higher age. The timing of the training gap seems to be driven by diverging career paths assoc...

the purpose of this study was to investigate disability and medical leave due to psychiatric disorders in patients referred to comission for psychiatric and neurological consultation of 682 patients who had been referred to the comission during 1993-94. results showed that psychiatric disorders and mood disorders led to occupational disability and medical leave at a significantly higher rate th...

Manpower is one of many fields in Indonesia which has the aim advancing Indonesian Economy and National Development. Female Labor also subjects Indonesian’s economic development. The basic difference between male female workers makes it nacessary to have several rights obtained, right menstrual leave obtained by Indonesian. implementation that occurs companies reflects people care about equaliz...
