Identity development in school makerspaces: Intentional design

Broadening participation informal stem education

Fasso W, Knight BA.
GSID: nZ22Yu012e4J
W Fasso, BA Knight - … Journal of Technology and Design Education, 2020 - Springer

Makerspaces are increasingly popular in K-12 schools, particularly when associated with STEM learning. Many schools are successfully entering the makerspace arena. Others face significant barriers in ideating their design, often resorting to tinkering, or the purchase of commercial kits...

CORRELATED EVOLUTION OF GENOME SIZE AND CELL VOLUME IN DIATOMS (BACILLARIOPHYCEAE)(1).

Journal of phycology

Connolly JA, Oliver MJ, Beaulieu JM, Knight CA, Tomanek L, Moline MA.
PMID: 27041049
J Phycol. 2008 Feb;44(1):124-31. doi: 10.1111/j.1529-8817.2007.00452.x.

A correlation between genome size and cell volume has been observed across diverse assemblages of eukaryotes. We examined this relationship in diatoms (Bacillariophyceae), a phylum in which cell volume is of critical ecological and biogeochemical importance. In addition to...

On a method of estimating the genetic correlation between characters measured in different experimental units.

TAG. Theoretical and applied genetics. Theoretische und angewandte Genetik

Fernando RL, Knights SA, Gianola D.
PMID: 24258544
Theor Appl Genet. 1984 Jan;67(2):175-8. doi: 10.1007/BF00317027.

Yamada's method of estimating genetic co-variances between traits measured in different experimental units is discussed. It is shown that if the data are unbalanced, this method gives biased estimates of genetic covariances unless the traits have identical genetic and...

Correlated evolution of chloroplast heat shock protein expression in closely related plant species.

American journal of botany

Knight CA, Ackerly DD.
PMID: 11250818
Am J Bot. 2001 Mar;88(3):411-8.

Interspecific variation in chloroplast low molecular weight (cLMW) HSP (heat shock protein) expression was examined with respect to phylogeny, species specific leaf area, chlorophyll fluorescence, and mean environmental conditions within species ranges. Eight species of Ceanothus (Rhamnaceae) were heat...

Melting inhibition and superheating of ice by an antifreeze glycopeptide.

Science (New York, N.Y.)

Knight CA, Devries AL.
PMID: 17750260
Science. 1989 Aug 04;245(4917):505-7. doi: 10.1126/science.245.4917.505.

The melting of pure ice single crystals can be inhibited by the presence of an antifreeze glycopeptide isolated from an Antarctic fish. This inhibition effect exhibits crystallographic dependence and can result in superheating of the crystal by heat conduction...

Indole-3-acetic Acid Synthesis in Tumorous and Nontumorous Species of Nicotiana.

Plant physiology

Liu ST, Katz CD, Knight CA.
PMID: 16660376
Plant Physiol. 1978 May;61(5):743-7. doi: 10.1104/pp.61.5.743.

The synthesis of indole-3-acetic acid (IAA) in the enzyme extracts of Nicotiana glauca, Nicotiana langsdorffii, their F1 hybrid, their amphidiploid hybrid, and the nontumorous mutant of the hybrid was investigated. Tryptamine, a possible precursor of IAA biosynthesis in Nicotiana...

Bound Form Indole-3-acetic Acid Synthesis in Tumorous and Nontumorous Species of Nicotiana.

Plant physiology

Liu ST, Gruenert D, Knight CA.
PMID: 16660235
Plant Physiol. 1978 Jan;61(1):50-3. doi: 10.1104/pp.61.1.50.

The synthesis of H(2)O-soluble and NaOH-hydrolyzable bound forms of indole-3-acetic acid (IAA) in petiole slices of Nicotiana glauca, Nicotiana langsdorffii, and their tumorous and nontumorous hybrids in the presence of exogenous (14)C-IAA was investigated. The synthesis of conjugates progressively...

Biomass carbon measurements and substrate utilization patterns of microbial populations from soils amended with cadmium, copper, or zinc.

Applied and environmental microbiology

Knight BP, McGrath SP, Chaudri AM.
PMID: 16535500
