Improving instructional leadership through the development of leadership content knowledge: The case of principal learning in algebra

science instruction

Johnson KR, Otten S, Steele MD.
GSID: waHT-I664WAJ
MD Steele, KR Johnson, S Otten… - Journal of Research …, 2015 - journals.sagepub.com

Instructional leadership is integral to improving mathematics teaching in secondary schools. However, administrators often lack sufficient content knowledge in mathematics to be …

Assessing journal quality in mathematics education

mathematics education

Nivens RA, Otten S.
GSID: yVYf-TdZeeEJ
RA Nivens, S Otten - Journal for Research in Mathematics Education, 2017 - pubs.nctm.org

In this Research Commentary, we describe 3 journal metrics–the Web of Science's Impact Factor, Scopus's SCImago Journal Rank, and Google Scholar Metrics' h5-index—and …

Mathematics teachers' motivations for, conceptions of, and experiences with flipped instruction

flipped classroom

Birisci S, de Z, Otten S.
GSID: nUnVgxaKO48J
Z de Araujo, S Otten, S Birisci - Teaching and Teacher Education, 2017 - Elsevier

Flipped instruction in school mathematics has been occurring more frequently. This study investigated two teachers' motivations for, conceptions of, and experiences with flipped …

Metal-ligand cooperative activation of nitriles by a ruthenium complex with a de-aromatized PNN pincer ligand.

Dalton transactions (Cambridge, England : 2003)

Eijsink LE, Perdriau SC, de Vries JG, Otten E.
PMID: 27727356
Dalton Trans. 2016 Oct 12;45(40):16033-16039. doi: 10.1039/c6dt02478e.

The pincer complex (PNN)RuH(CO), with a de-aromatized pyridine in the ligand backbone, is shown to react with nitriles in a metal-ligand cooperative manner. This leads to the formation of a series of complexes with new Ru-N(nitrile) and C(ligand)-C(nitrile) bonds....

Effect of fatigue on landing performance assessed with the landing error scoring system (less) in patients after ACL reconstruction. A pilot study.

International journal of sports physical therapy

Gokeler A, Eppinga P, Dijkstra PU, Welling W, Padua DA, Otten E, Benjaminse A.
PMID: 24944848
Int J Sports Phys Ther. 2014 May;9(3):302-11.

BACKGROUND: Fatigue has been shown to affect performance of hop tests in patients after anterior cruciate ligament reconstruction (ACLR) compared to uninjured controls (CTRL). This may render the hop test less sensitive in detecting landing errors. The primary purpose...

Asymmetric Synthesis of Second-Generation Light-Driven Molecular Motors.

The Journal of organic chemistry

van Leeuwen T, Danowski W, Otten E, Wezenberg SJ, Feringa BL.
PMID: 28459576
J Org Chem. 2017 May 19;82(10):5027-5033. doi: 10.1021/acs.joc.7b00852. Epub 2017 May 01.

The enantiomeric homogeneity of light-driven molecular motors based on overcrowded alkenes is crucial in their application as either unidirectional rotors or as chiral multistate switches. It was challenging to obtain these compounds as single enantiomers via the established synthetic...

The Co-Development of Parenting Stress and Childhood Internalizing and Externalizing Problems.

Journal of psychopathology and behavioral assessment

Stone LL, Mares SH, Otten R, Engels RC, Janssens JM.
PMID: 27069304
J Psychopathol Behav Assess. 2016;38:76-86. doi: 10.1007/s10862-015-9500-3. Epub 2015 Aug 21.

Although the detrimental influence of parenting stress on child problem behavior is well established, it remains unknown how these constructs affect each other over time. In accordance with a transactional model, this study investigates how the development of internalizing...

Reduction of (Formazanate)boron Difluoride Provides Evidence for an N-Heterocyclic B(I) Carbenoid Intermediate.

Inorganic chemistry

Chang MC, Otten E.
PMID: 26252471
Inorg Chem. 2015 Sep 08;54(17):8656-64. doi: 10.1021/acs.inorgchem.5b01287. Epub 2015 Aug 07.

Despite the current interest in structure and reactivity of sub-valent main group compounds, neutral boron analogues of N-heterocyclic carbenes have been elusive due to their high reactivity. Here we provide evidence that 2-electron reduction of a (formazanate)BF2 precursor leads...

Antibodies against Apoptotic Cells Present in End-stage Lung Disease Patients Do Not Correlate with Clinical Outcome after Lung Transplantation.

Frontiers in immunology

Budding K, van de Graaf EA, Kardol-Hoefnagel T, Oudijk ED, Kwakkel-van Erp JM, Hack CE, Otten HG.
PMID: 28377770
Front Immunol. 2017 Mar 21;8:322. doi: 10.3389/fimmu.2017.00322. eCollection 2017.

Antibodies against HLA and non-HLA are associated with transplantation outcome. Recently, pretransplant serum IgG antibody levels against apoptotic cells were found to correlate with kidney allograft loss. We investigated the presence of these antibodies in lung transplantation (LTx) patients...

An "ingredients" approach to functional self-synthesizing materials: a metal-ion-selective, multi-responsive, self-assembled hydrogel.

Chemistry (Weinheim an der Bergstrasse, Germany)

Li J, Cvrtila I, Colomb-Delsuc M, Otten E, Otto S.
PMID: 25332188
Chemistry. 2014 Nov 24;20(48):15709-14. doi: 10.1002/chem.201404977. Epub 2014 Oct 21.

New methodology for making novel materials is highly desirable. Here, an "ingredients" approach to functional self-assembled hydrogels was developed. By designing a building block to contain the right ingredients, a multi-responsive, self-assembled hydrogel was obtained through a process of...

Transformation of vitis tissue by different strains of Agrobacterium tumefaciens containing the T-6b gene.

Plant cell reports

Berres R, Otten L, Tinland B, Malgarini-Clog E, Walter B.
PMID: 24202984
Plant Cell Rep. 1992 May;11(4):192-5. doi: 10.1007/BF00232531.

Stem pieces and leaf disks of Vitis spp. were cocultured with Agrobacterium tumefaciens strains carrying the UidA (ß-glucuronidase = GUS) gene. The transformation efficiency was highly increased by using a modified T-6b gene (a gene from pTiTm4) which interferes...
