Motivation, Mindset, and Grading Systems

This action research study examines whether students in a standards-based grading environment are more intrinsically motivated than students in traditional grading environment. Additionally, it examines whether students in a standards-based grading environment exhibit more of a fixed or growth mindset compared to students in a traditional grading environment. The participants were 72 sixth grade students in a standards-based grading classroom environment, and 32 students in a traditional grading-based classroom environment. A survey with statements reflecting students’ intrinsic motivation, extrinsic motivation, fixed mindset, and growth mindset was administered to both groups of students. The survey results suggest that the grading environment, standards-based or traditional, does not account for students’ levels of intrinsic and extrinsic motivation, nor does it predict whether a student has a fixed or growth mindset

Evaluation of Soybean Varieties in the Northern Uniform Soybean Test

The Northern Uniform Soybean Test is used to evaluate soybean varieties produced by several public breeding programs in the Northern portion of the United States and Canada. In 2009, five public breeding programs participated in the Northern Uniform Soybean Test (Maturity Group I). Public breeders are allowed to enter varieties in the Uniform Test in exchange for growing locations for the test. Material entered in the Uniform Test is generally from advanced stages of a breeding program. The Uniform Soybean Test is an efficient method for soybean breeders to get multiple location data in comparison to each individual program growing their own locations. It also produces useful information by comparing soybean lines from multiple programs and identifies lines from other states that produce well in northern Iowa. Results from these tests are used by breeders to select varieties with superior yield and/or disease resistance to continue advancement to variety release. These results are also used to demonstrate positive characteristics to growers and other interested parties

Evaluation of Soybean Varieties in the Northern Uniform Soybean Test—Uniform Test III

The Northern Uniform Soybean Test is used to evaluate soybean varieties produced by several public breeding programs in the northern portion of the United States and Canada. In 2010, five public breeding programs participated in the Northern Uniform Soybean Test (Uniform Test III). Public breeders are allowed to enter varieties into the Uniform Test in exchange for growing locations for the test. Material entered into the Uniform Test is generally in advanced stages of a breeding program. The Uniform Soybean Test is a method for soybean breeders to get multiple location data, in a very efficient manner in comparison to each individual program growing their own locations. It also produces useful information by comparing soybean lines from multiple programs, and identifies lines from other states that produce well in southern Iowa. Results from these tests are used by breeders to select varieties with superior yield and/or disease resistance to continue advancement on a trek toward variety release. These results are also used to demonstrate positive characteristics to growers and other interested parties

A study of hypertension in twins

A study of the blood pressure of 86 pairs of like-sexed twins over age 40 selected at random was performed. Twelve per cent were found to have a diastolic blood pressure in excess of 94 mm. Hg. In 4 out of 5 identical twin sets both members were found to have hypertension of about equal magnitude. In the fifth set, the predetermined definition of diastolic hypertension was not met in one member of the pair, although the systolic blood pressure was clearly elevated. In two identical twin sets, where information concerning previous blood pressure could be obtained, the age of onset of the hypertension differed. Among the 49 dizygetic twin sets, diastolic hypertension was found in 15 per cent of the individuals. In 3 of 12 of these pairs, it was present in both members.Since the prevalence of hypertension after age 40 in the identical twin sample resembles that in the population at large, it is concluded that the ultimate development of this condition is heavily dependent on genetic influences.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/32777/1/0000150.pd

Interplay of initial deformation and Coulomb proximity on nuclear decay

Alpha particles emitted from an excited projectile-like fragment (PLF*) formed in a peripheral collision of two intermediate-energy heavy ions exhibit a strong preference for emission towards the target-like fragment (TLF). The interplay of the initial deformation of the PLF* caused by the reaction, Coulomb proximity, and the rotation of the PLF* results in the observed anisotropic angular distribution. Changes in the shape of the angular distribution with excitation energy are interpreted as being the result of forming more elongated initial geometries in the more peripheral collisions.Comment: 4 figure
