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...

Repeated airway exposure to wood dust has been reported to cause adverse respiratory effects such as asthma and chronic bronchitis. In our recent study, we found that exposure of mice to oak dust induced more vigorous lung inflammation compared to birch dust exposure. In the present study, we assessed the immunomodulatory effects of repeated intranasal exposure to oak dust both in nonallergic a...

Oak-hickory forests of the Arkansas Ozarks recently incurred extensive tree mortality due in part to a native wood-boring beetle, the red oak borer Enaphalodes rufulus (Haldeman) (Coleoptera: Cerambycidae). Historically, red oak borer has existed throughout southeastern U.S. forests at relatively low population levels, but Arkansas infestation estimates in 2001 and 2003 reported much higher pop...

The atmospheric hydrocarbon budget is important for predicting ozone episodes and the effects of pollution mitigation strategies. Isoprene emission from plants is an important part of the atmospheric hydrocarbon budget. We measured isoprene emission capacity at the bottom, middle, and top of the canopies of a white oak (Quercus alba L.) tree and a red oak (Quercus rubra L.) tree growing adjacen...

About 95% of swamp tupelo (Nyssa sylvatica var. biflora (Walt.) Sarg.) and sweetgum (Liquidambar styraciflua L.) seedlings survived continuous root flooding for more than two years, whereas none of the swamp chestnut oak (Quercus michauxii Nutt.) and cherrybark oak (Q. falcata var. pagodifolia Ell.) seedlings survived one year of flooding. Death of oak seedlings occurred in phases associated wi...

the effect of grape pomace (vitis vinifera) and in oak leaf (quercus libani) tannins by three runs of in vitro gas production on the organic matter digestibility (omd) and in situ dry matter (dm) and crude protein (cp) disappearance were studied in four sheeps. polyethylene glycol (peg) was used to deactivate the tannins. in vitro gas production was recorded at 2, 4, 6, 8, 12, 48, 72, 96 and 12...
