With our Spring 2021 volume, Studies in Applied Linguistics & TESOL (SALT) celebrates its twentieth anniversary. The journal was founded 2001, originally called Working Papers and Linguistics. In the late 1990s, a young faculty member ZhaoHong Han joined Program at Teachers College. Inspired by published University of Hawaii ESL -- one that evolved over time into very influential outlet, Dr...
Several studies have claimed that reduction in body size comprises a nearly universal response to global warming; however, doubts about the validity of this pattern for endothermic species have been raised recently. Accordingly, we assessed temporal changes in body mass for 27 bird and 17 mammal species, to evaluate if a reduction in body size during the 20th century is a widespread phenomenon ...
The aim of the present research was to evaluate the growth rate of the weight and body measurements of pheasants reared up to the 24th week of life, fed with all-mash mixtures. In the 3rd, 8th, 12th , 16th, 20th and 24th week of life the birds were weighed individually and their body measurements were measured based on which the growth rate indices of the traits researched were calculated. It w...
With amplified warming and record sea ice loss, the Arctic is the canary of global warming. The historical Arctic warming is poorly understood, limiting our confidence in model projections. Specifically, Arctic surface air temperature increased rapidly over the early 20th century, at rates comparable to those of recent decades despite much weaker greenhouse gas forcing. Here, we show that the c...
In 2002, Munk defined an important enigma of 20th century global mean sea-level (GMSL) rise that has yet to be resolved. First, he listed three canonical observations related to Earth's rotation [(i) the slowing of Earth's rotation rate over the last three millennia inferred from ancient eclipse observations, and changes in the (ii) amplitude and (iii) orientation of Earth's rotation vector ove...
Ovarian and testicular tumors were induced in the offspring (Fi gen eration) of MRC rats that received single or multiple doses of Nnitrosobis(2-oxopropyl)amine on the 14th, 18th, and/or 20th days of pregnancy. The ovarian tumor incidence was significantly higher (46%) in the FI generation exposed to the carcinogen a single time at the 18th day of gestation, when compared to those exposed at th...
Ovarian and testicular tumors were induced in the offspring (F1 generation) of MRC rats that received single or multiple doses of N-nitrosobis(2-oxopropyl)amine on the 14th, 18th, and/or 20th days of pregnancy. The ovarian tumor incidence was significantly higher (46%) in the F1 generation exposed to the carcinogen a single time at the 18th day of gestation, when compared to those exposed at th...
It is quite fitting for a symposium reviewing progress in infant nutrition in the 20th century to start with a review of infant mortality rates during that time period. Indeed, it has been a truism in public health that, within limits, the infant mortality rate of any community, large or small, reflected its general state of health better than any other single indicator. Although no longer vali...
