Consider the following strategic environment: Players. Assume that in each period, civilian i, living in some region, inelastically generates per period income y, using one unit of labor. What the civilian produces can be consumed or transferred, but not saved or invested. Further, assume that production for each civilian takes place subject to some base consumption requirement in the previous ...

Fetal cholelithiasis is a rare finding during a third-trimester ultrasound with an average incidence rate of 0.07-1.15%. We report a case of fetal cholelithiasis in twins, observed in a patient with monochorionic diamniotic twin pregnancy hospitalized at our unit for signs of premature labor. We present the outcome of the 2 neonates with a clinical and sonographic follow-up. In addition, we off...

In order to replace the univariate indicators standard in the literature (cp. [Opp96]) by a multivariate representation of business cycles, the relevant ’stylized facts’ are to be identified which optimally characterize the development of business cycle phases. Based on statistical classification methods we found that, somewhat surprisingly, only two variables, ’wage and salary earners’ and ’un...

When a delay occurs in a project, there are basically two options: prescribing overtime work and injecting additional resources, in order to meet the project schedule of certain activities. This paper uses economic analysis to demonstrate that a decision maker will select the most suitable alternative by considering productivity losses in overtime work and the relative unit costs between differ...

The unit values of US manufacturing imports vary widely within very narrowly defined products. In cross-section, unit values are higher for varieties exported by capital and skill abundant countries, and they increase with the capital intensity of exporters’ production techniques. Over time, the same products increasingly are sourced from more disparate countries. These facts reject ‘old’ trade...

This paper evaluates in emergy terms the resource use and environmental performance of the Italian agricultural sector across levels, from local scale (olive, lemon and grape farms), through regional scale (Campania region) up to the national scale (whole Italy). The evolution over time (from 1985 to 2006) is also investigated to take into account how the demand for environmental support change...

There are four principles in the analysis of tax incidence: 1. The entire burden of a tax must be traced to individuals. Businesses may remit taxes, but only individuals–shareholders, employees, customers–can bear the burden of taxes. 2. The ultimate distribution of the tax burden may di¤er from the statutory liability; that is, the tax burden may be shifted because prices change. 3. The long r...

Ants live in organized societies with a marked division of labor among workers, but little is known about how this division of labor is generated. We used a tracking system to continuously monitor individually tagged workers in six colonies of the ant Camponotus fellah over 41 days. Network analyses of more than 9 million interactions revealed three distinct groups that differ in behavioral rep...

OBJECTIVE To determine colonization rates of Staphylococcus aureus given the potential for future intervention trials aimed at reducing surgical-site infectious morbidity, and to estimate methicillin-resistant Staphylococcus aureus (MRSA) rates in our patient population. STUDY DESIGN Prospective pilot investigation comprising data from 104 gravidas admitted to an urban labor and delivery unit...
