Do television debates in multiparty systems affect viewers? A quasi‐experimental study with first‐time voters

quasi-experimental designs

Aalberg T.
GSID: wae0Rb5tr3EJ
T Aalberg, AT Jenssen - Scandinavian Political Studies, 2007 - Wiley Online Library

… Based on a quasi-experimental design prior to the 2001 Norwegian parliamentary election, this study finds that the outcome of the television debates does matter. Winning a debate can actually make a difference, and significant changes in issue ownership...

The origin and early diversification of tetrapods

… increase in homoplasy in the tetrapod stem group. It also suggests that ecological diversity and biogeographical provinciality in the tetrapod stem group have been underestimated. …

The origin and early diversification of tetrapods

STEM and diversification

Ahlberg P.
GSID: aw1dJlSCnREJ
P Ahlberg, A Milner - Shaking the tree: readings from Nature in …, 2000 - books.google.com

… primitive stem tetrapods, with Crassigyrinus (discussed below) farther up the stem. The loxommatids are ambiguous in their position and could be either stem tetrapods or stem amniotes…

Endocast and bony labyrinth of a stem gnathostome shed light on the earliest diversification of jawed vertebrates

STEM and diversification

Ahlberg PE, Giles S, Hu Y, Young G.
GSID: FCf3wyaOqUEJ
Y Zhu, S Giles, G Young, Y Hu, M Bazzi, PE Ahlberg… - bioRxiv, 2020 - biorxiv.org

Our understanding of the earliest evolution of jawed vertebrates depends on a credible phylogenetic assessment of the jawed stem gnathostomes collectively known as 'placoderms'. However, their relationships, and even whether 'placoderms' represent a single radiation or a paraphyletic array,...

Knowing but not knowing: providing maternity care in the context of HIV/AIDS in rural Zimbabwe.

African journal of AIDS research : AJAR

Mathole T, Lindmark G, Ahlberg BM.
PMID: 25875237
Afr J AIDS Res. 2006 Sep;5(2):133-9. doi: 10.2989/16085900609490373.

Individual interviews with 25 nurses and midwives revealed their experiences with providing maternity care in rural Zimbabwe. These first-hand accounts especially illuminate the complexities of providing maternity care in the context of HIV/AIDS. The caregivers described feeling troubled by...

The bifurcation point of the oxygen reduction reaction on Au-Pd nanoalloys.

Faraday discussions

Staszak-Jirkovský J, Ahlberg E, Panas I, Schiffrin DJ.
PMID: 27089504
Faraday Discuss. 2016 Jul 04;188:257-78. doi: 10.1039/c5fd00233h.

The oxygen reduction reaction is of major importance in energy conversion and storage. Controlling electrocatalytic activity and its selectivity remains a challenge of modern electrochemistry. Here, first principles calculations and analysis of experimental data unravel the mechanism of this...

Interaction of dermatologically relevant nanoparticles with skin cells and skin.

Beilstein journal of nanotechnology

Vogt A, Rancan F, Ahlberg S, Nazemi B, Choe CS, Darvin ME, Hadam S, Blume-Peytavi U, Loza K, Diendorf J, Epple M, Graf C, Rühl E, Meinke MC, Lademann J.

Beilstein J Nanotechnol. 2014 Dec 08;5:2363-73. doi: 10.3762/bjnano.5.245. eCollection 2014.

The investigation of nanoparticle interactions with tissues is complex. High levels of standardization, ideally testing of different material types in the same biological model, and combinations of sensitive imaging and detection methods are required. Here, we present our studies...

Visual exploration of HTS databases: bridging the gap between chemistry and biology.

Drug discovery today

Ahlberg C.
PMID: 10431147
Drug Discov Today. 1999 Aug;4(8):370-376. doi: 10.1016/s1359-6446(99)01373-2.

As pharmaceutical corporations are under pressure to shorten research and development (R&D) cycles for new drugs, novel technologies are being deployed, producing a data explosion in the research environment. Researchers can then become the bottleneck in the R&D cycle...

Does training in a virtual reality simulator improve surgical performance?.

Surgical endoscopy

Ahlberg G, Heikkinen T, Iselius L, Leijonmarck CE, Rutqvist J, Arvidsson D.
PMID: 11961622
Surg Endosc. 2002 Jan;16(1):126-9. doi: 10.1007/s00464-001-9025-6. Epub 2001 Nov 12.

BACKGROUND: The development of computerized surgical simulators in a virtual reality environment demands models for proper validation. Recent investigations have shown that a virtual reality simulator (MIST-VR) is a reliable tool for the assessment of laparoscopic psychomotor skills and...

Development of a harmonized method for the profiling of amphetamines. I. Synthesis of standards and compilation of analytical data.
