Immigration and low birthweight in the US: The role of time and timing

The literature exploring the health consequences of immigration is largely dominated by efforts to replicate, across outcomes and populations, and explain two widely observed findings: that foreign nativity is protective (yielding the “healthy migrant effect” or “immigrant paradox”) and that the health advantage of immigrants diminishes over time in the host country. In this study, we focus on the second of these patterns and provide evidence that a lifecourse perspective can help to explain the apparent deterioration in health by incorporating attention to immigrants’ timing of arrival. We examine the role of immigrants’ exposure to the US, in terms of both age at immigration and length of residence, in shaping birthweight, a well measured and consequential marker of health, and maternal smoking, an important risk factor for low birthweight.

Terminal and rotaterminal crossbreeding systems for pork producers (1995)

Crossbreeding is a widely established management practice among commercial pork producers. Over the years, the industry has used rotational crossbreeding programs extensively. Rotational programs are relatively easy to operate, enable pork producers to develop their own females and exploit most of the possible heterosis.Reprint 6/95/5M

Analyses of Certain Clays Used for Making Paving Brick for Cedar Rapids

The following analyses were made several years ago for Mr. E. P. Boynton, the city engineer of Cedar Rapids. The clays were taken from four companies in Des Moines; each having their plant in a different part of that city

Purchasing a herd boar for commercial swine production

"Success in commercial swine production is determined by a pork producer's ability to use resources efficiently. However, the level of efficiency that can be obtained is a set by the genetic merit of the breeding herd. The genetic merit of the breeding herd is established by the crossbreeding program used and the introduction of new seedstock either by purchasing females or boars."--First page.Ronald O.

Pure Food Laws

The demand for cheap goods and the intense strain produced by commercial competition has induced many dealers and manufacturers to adulterate their products. This practice enables them to satisfy the buyer and outwit their competitors, not to speak of the immediate financial advantage

Municipal Hygiene - Part II - Milk

It is the purpose of this paper to help popularize the scientific facts that have been discovered by the research laboratories which are controlled and fostered by our national government and individual States of the Union, and by the laboratories of the denominational institutions of higher education. Vast sums of money are spent each year to maintain such work. No one can question their efficiency or practical value. Such knowledge is not prized as highly as it should be, nor are the discoveries as thoroughly known as they should be. The bulletins that are issued from the various stations are within the reach of everyone, they are absolutely free. Like streams that have their origin in the ice fields of remote mountains, they come in gentle cascades to satisfy the thirsty and revive life, and give hope for better and higher life. Doth not Wisdom cry? and Understanding put forth her voice? She crieth at the gates, at the entry, at the coming, at the doors

Eighty Third Field Artillery Battalion

The history of the 83rd Armored Field Artillery Battalion began on June 15th, 1832 when the First Regiment of Cavalry was organized by Act of Congress, as the Battalion of Mounted Rangers. A reorganization on March 21st, 1833, changed the title to, the Regiment of Dragoons. Later in 1836 it was designated as the First Dragoons, and in 1861 was again known as the 1st Cavalry.https://digicom.bpl.lib.me.us/ww_reg_his/1025/thumbnail.jp

Purchasing a herd boar for commercial swine production

AGRICULTURALMU GuidePUBLISHED BY UNIVERSITY EXTENSION, UNIVERSITY OF MISSOURI-COLUMBIASwine BreedingSuccess in commercial swine production is determined by a pork producer's ability to use resources efficiently. However, the level of efficiency that can be obtained is set by the genetic merit of the breeding herd. The genetic merit of the breeding herd is established by the crossbreeding program used and the introduction of new seedstock either by purchasing females or boars. The most popular crossbreeding programs have been rotational programs that produce replacement females so that only boars need to be brought into the herd. Farmers can use other more specialized crossbreeding programs, only purchase boars as well.
