A Review of The Literature To Inform the Efficacy of a Spatial Skills Intervention For Secondary Level STEM Education

Stem education interventions

Buckley J, Dunbar R, Maquet L.
GSID: rsq-uW9_o0YJ
L Maquet, R Dunbar, J Buckley, N Seery, S Sorby - researchgate.net

The development of spatial skills within STEM fields is of growing importance with studies showing correlation between spatial skills in adolescence and the attainment of advanced degrees in STEM later in life. The rising need for STEM professionals is...

Sex differences in social focus across the life cycle in humans.

Royal Society open science

Bhattacharya K, Ghosh A, Monsivais D, Dunbar RI, Kaski K.
PMID: 27152223
R Soc Open Sci. 2016 Apr 06;3(4):160097. doi: 10.1098/rsos.160097. eCollection 2016 Apr.

Age and gender are two important factors that play crucial roles in the way organisms allocate their social effort. In this study, we analyse a large mobile phone dataset to explore the way life history influences human sociality and...

Space charge effects on relative peak heights in fourier transform-ion cyclotron resonance spectra.

Journal of the American Society for Mass Spectrometry

Uechi GT, Dunbar RC.
PMID: 24234640
J Am Soc Mass Spectrom. 1992 Oct;3(7):734-41. doi: 10.1016/1044-0305(92)87086-E.

Ion trajectory calculations have confirmed that space charge interactions can be a source for mass discrimination seen in Fourier transform-ion cyclotron resonance (FT-ICR) spectra. As compared with the previously recognized mechanism of z-axis excitation, ion-ion repulsion is a mechanism...

Complexes of Ni(ii) and Cu(ii) with small peptides: deciding whether to deprotonate.

Physical chemistry chemical physics : PCCP

Dunbar RC, Martens J, Berden G, Oomens J.
PMID: 27711408
Phys Chem Chem Phys. 2016 Sep 29;18(38):26923-26932. doi: 10.1039/c6cp03974j.

The observed variety of metal-ion complexation sites offered by peptides reflects a basic tension between charge solvation of the ion by Lewis-basic chelating groups versus amide nitrogen deprotonation and formation of metal-nitrogen bonds. Gas-phase models of metal-ion coordination can...

Genome Sequences of Newly Isolated Mycobacteriophages Forming Cluster S.

Genome announcements

Mills ML, Bragg J, Bruce A, Dehn A, Drouin J, Hefner M, Katon D, McHugh D, Zeba F, Bowman CA, Cresawn SG, Jacobs-Sera D, Russell DA, Pope WH, Hatfull GF, Dunbar DA, Zegers GP, Page ST.
PMID: 27688332
Genome Announc. 2016 Sep 29;4(5). doi: 10.1128/genomeA.00933-16.

We describe the genomes of two mycobacteriophages, MosMoris and Gattaca, newly isolated on Mycobacterium smegmatis The two phages are very similar to each other, differing in 61 single nucleotide polymorphisms and six small insertion/deletions. Both have extensive nucleotide sequence...

Social networks, support cliques, and kinship.

Human nature (Hawthorne, N.Y.)

Dunbar RI, Spoors M.
PMID: 24203093
Hum Nat. 1995 Sep;6(3):273-90. doi: 10.1007/BF02734142.

Data on the number of adults that an individual contacts at least once a month in a set of British populations yield estimates of network sizes that correspond closely to those of the typical "sympathy group" size in humans....

Photodissociation spectroscopy of gas-phase ferrocene cation.

Journal of the American Society for Mass Spectrometry

Faulk JD, Dunbar RC.
PMID: 24242167
J Am Soc Mass Spectrom. 1991 Apr;2(2):97-102. doi: 10.1016/1044-0305(91)80001-N.

The optical absorption spectrum of gas-phase ferrocene cation was measured by photodissociation (PO) spectroscopy between 570 nm and 643 nm. The PO process was loss of a cyclopentadienyl ring from the parent cation. Some structure was observed in the...

Kahalalides: Bioactive Peptides from a Marine Mollusk Elysia rufescens and Its Algal Diet Bryopsis sp.(1).

The Journal of organic chemistry

Hamann MT, Otto CS, Scheuer PJ, Dunbar DC.
PMID: 11667527
J Org Chem. 1996 Sep 20;61(19):6594-6600. doi: 10.1021/jo960877+.

In addition to the previously reported bioactive kahalalide F six new peptides are described. Six of these, including kahalalide F, are cyclic depsipeptides, ranging from a C(31) tripeptide to a C(75) tridecapeptide isolated from a sacoglossan mollusk, Elysiarufescens. The...

THE STAGES OF THE PEPTIC HYDROLYSIS OF EGG ALBUMIN.

The Journal of general physiology

McFarlane J, Dunbar VE, Borsook H, Wasteneys H.
