Pseudoreplication: a sine qua non for regional ecology

quasi-experiments

Hargrove WW, Pickering J.
GSID: lxsdQrh9eoYJ
WW Hargrove, J Pickering - Landscape Ecology, 1992 - Springer

… We suggest quasi-experiments as a compromise between classical experimentation and descriptive techniques. Quasi-experiments assume … Quasi-experiments may take advantage of natural phenomena or catastrophes which alter or manipulate wide areas. E1 Nifio, the Gulf …

Bringing about a balance.

Community mental health journal

Hargrove DS.
PMID: 2055003
Community Ment Health J. 1991 Jun;27(3):167-70. doi: 10.1007/BF00752418.

Kupers' comment on the cyclical nature of the recent history of mental health in the United States is important and hopeful. Another dimension of the current public mental health scene is the decrease of the federal role in the...

Dual Window Pattern Recognition Classifier for Improved Partial-Hand Prosthesis Control.

Frontiers in neuroscience

Earley EJ, Hargrove LJ, Kuiken TA.
PMID: 26941599
Front Neurosci. 2016 Feb 23;10:58. doi: 10.3389/fnins.2016.00058. eCollection 2016.

Although partial-hand amputees largely retain the ability to use their wrist, it is difficult to preserve wrist motion while using a myoelectric partial-hand prosthesis without severely impacting control performance. Electromyogram (EMG) pattern recognition is a well-studied control method; however,...

Virtual Constraint Control of a Powered Prosthetic Leg: From Simulation to Experiments with Transfemoral Amputees.

IEEE transactions on robotics : a publication of the IEEE Robotics and Automation Society

Gregg RD, Lenzi T, Hargrove LJ, Sensinger JW.
PMID: 25558185
IEEE Trans Robot. 2014 Dec;30(6):1455-1471. doi: 10.1109/TRO.2014.2361937.

Recent powered (or robotic) prosthetic legs independently control different joints and time periods of the gait cycle, resulting in control parameters and switching rules that can be difficult to tune by clinicians. This challenge might be addressed by a...

Cross-sectional survey on minimally invasive mitral valve surgery.

Annals of cardiothoracic surgery

Misfeld M, Borger M, Byrne JG, Chitwood WR, Cohn L, Galloway A, Garbade J, Glauber M, Greco E, Hargrove CW, Holzhey DM, Krakor R, Loulmet D, Mishra Y, Modi P, Murphy D, Nifong LW, Okamoto K, Seeburger J, Tian DH, Vollroth M, Yan TD.
PMID: 24349974
Ann Cardiothorac Surg. 2013 Nov;2(6):733-8. doi: 10.3978/j.issn.2225-319X.2013.11.11.

BACKGROUND: Minimally invasive mitral valve surgery (MIMVS) has become a standard technique to perform mitral valve surgery in many cardiac centers. However, there remains a question regarding when MIMVS should not be performed due to an increased surgical risk....

Subtalar Pronation Does Not Influence Impact Forces or Rate of Loading During a Single-Leg Landing.

Journal of athletic training

Hargrave MD, Carcia CR, Gansneder BM, Shultz SJ.
PMID: 12937467
J Athl Train. 2003 Mar;38(1):18-23.

OBJECTIVE: To identify the influence of static subtalar pronation (as measured by weight-bearing navicular drop [ND]) on ground impact forces and rate of loading during a single-leg landing. DESIGN AND SETTING: Subjects were grouped (n = 16 per group)...

Switching stereoselectivity in rhodium-catalysed 1,4-additions: The asymmetric synthesis of 2-substituted pyrrolizidinones.

Chemical communications (Cambridge, England)

Hargrave JD, Bish G, Frost CG.
PMID: 17057853
Chem Commun (Camb). 2006 Nov 13;(42):4389-91. doi: 10.1039/b610128c. Epub 2006 Oct 03.

The appropriate choice of organometallic nucleophile enables the straightforward preparation of different stereoisomers of 2-substituted pyrrolizidinones utilising the rhodium-catalysed 1,4-addition reaction.

Intramuscular ketamine to facilitate pediatric central vascular access.

CJEM

Denmark TK, Hargrove JR, Brown L.
PMID: 17382002
CJEM. 2004 Jul;6(4):259-62. doi: 10.1017/s1481803500009222.

OBJECTIVES: Obtaining prompt vascular access in young children presenting to the emergency department (ED) is frequently both necessary and technically challenging. The objective of our study was to describe our experience using intramuscular (IM) ketamine to facilitate the placement...

Origin of stability in branched alkanes.

Chemistry (Weinheim an der Bergstrasse, Germany)

Kemnitz CR, Mackey JL, Loewen MJ, Hargrove JL, Lewis JL, Hawkins WE, Nielsen AF.
PMID: 20432414
Chemistry. 2010 Jun 18;16(23):6942-9. doi: 10.1002/chem.200902550.

The potential origins of stability in branched alkanes are investigated, paying close attention to two recent hypotheses: geminal steric repulsion and protobranching. All alkane isomers through C(6)H(14) along with heptane and octane were investigated at the MPW1B95/6-311++G(d,p) level. Their...

Destabilization of tyrosine aminotransferase by amino acids.

Amino acids

Hargrove JL, Liu C.
PMID: 24186125
Amino Acids. 1994 Oct;7(3):279-89. doi: 10.1007/BF00807703.

Several L-amino acids (tyrosine, glutamate, methionine, tryptophan, and phenylalanine) and penicillamine destabilized purified tyrosine aminotransferase by removing enzyme-bound pyridoxal 5'-phosphate. The destabilization was measured as a progressive loss of enzyme activity in samples taken at intervals from a primary...
