International marketing journals : a preliminary regional and institutional examination of research productivity

Contributions to marketing knowledge are becoming more global (Stremersch and Verhoef, 2005). This paper explores the issue of regional contribution to the international marketing area, which could be expected to be more global than other areas. Publications within four leading international marketing journals were reviewed over a five-year period (1999-2003). Findings suggested that approximately 50 percent of the works were authored by academics outside North America.<br /

Instream Woody Debris and Riparian Forest Characteristics in the Sabine River, Texas

We examined instream large woody debris (LWD) dynamics on the Sabine River, TX. All wood \u3e10 cm in diameter and \u3e2 m long was measured on four river meanders (meander wavelengths) below the dam on Toledo Bend Reservoir. We determined LWD species, degree of decay, bank orientation, jam association, and stage contact. We also measured riparian vegetation characteristics on each meander. LWD volumes were significantly greater at the site immediately below Toledo Bend Dam, due to the relatively steeper channel gradient and higher rates of channel erosion. Based on mass balance estimates, between 11 and 21% of total annual recruitment came from upstream fluvial transport, and the remainder resulted from bank erosion and tree mortality. We estimated average LWD residence time to be 12–14 years. The lower Sabine River is transport-limited for sediment, and the same is true for LWD. Based on these measurements, it is unlikely that Toledo Bend Reservoir is having a significant impact on LWD dynamics at the measurement reaches due to lacustrine wood storage. Of greater concern in the study system are riparian forest degradation and invasive species spread, which may dramatically affect future LWD loadings and residence times, and thus, riverine biota

Feasibility Evaluation of Commercially Available Video Conferencing Devices to Technically Direct Untrained Nonmedical Personnel to Perform a Rapid Trauma Ultrasound Examination.

Introduction: Point-of-care ultrasound (POCUS) is a rapidly expanding discipline that has proven to be a valuable modality in the hospital setting. Recent evidence has demonstrated the utility of commercially available video conferencing technologies, namely, FaceTime (Apple Inc, Cupertino, CA, USA) and Google Glass (Google Inc, Mountain View, CA, USA), to allow an expert POCUS examiner to remotely guide a novice medical professional. However, few studies have evaluated the ability to use these teleultrasound technologies to guide a nonmedical novice to perform an acute care POCUS examination for cardiac, pulmonary, and abdominal assessments. Additionally, few studies have shown the ability of a POCUS-trained cardiac anesthesiologist to perform the role of an expert instructor. This study sought to evaluate the ability of a POCUS-trained anesthesiologist to remotely guide a nonmedically trained participant to perform an acute care POCUS examination. Methods: A total of 21 nonmedically trained undergraduate students who had no prior ultrasound experience were recruited to perform a three-part ultrasound examination on a standardized patient with the guidance of a remote expert who was a POCUS-trained cardiac anesthesiologist. The examination included the following acute care POCUS topics: (1) cardiac function via parasternal long/short axis views, (2) pneumothorax assessment via pleural sliding exam via anterior lung views, and (3) abdominal free fluid exam via right upper quadrant abdominal view. Each examiner was given a handout with static images of probe placement and actual ultrasound images for the three views. After a brief 8 min tutorial on the teleultrasound technologies, a connection was established with the expert, and they were guided through the acute care POCUS exam. Each view was deemed to be complete when the expert sonographer was satisfied with the obtained image or if the expert sonographer determined that the image could not be obtained after 5 min. Image quality was scored on a previously validated 0 to 4 grading scale. The entire session was recorded, and the image quality was scored during the exam by the remote expert instructor as well as by a separate POCUS-trained, blinded expert anesthesiologist. Results: A total of 21 subjects completed the study. The average total time for the exam was 8.5 min (standard deviation = 4.6). A comparison between the live expert examiner and the blinded postexam reviewer showed a 100% agreement between image interpretations. A review of the exams rated as three or higher demonstrated that 87% of abdominal, 90% of cardiac, and 95% of pulmonary exams achieved this level of image quality. A satisfaction survey of the novice users demonstrated higher ease of following commands for the cardiac and pulmonary exams compared to the abdominal exam. Conclusions: The results from this pilot study demonstrate that nonmedically trained individuals can be guided to complete a relevant ultrasound examination within a short period. Further evaluation of using telemedicine technologies to promote POCUS should be evaluated

Zerebrale Periinfarktdepolarisation: zeitliche und topographische Dynamik in simultaner Magnetoencephalographie und Elektrokortikographie nach Mediaokklusion bei der Ratte

Diese Arbeit untersucht zerebrale Periinfarktdepolarisationen nach fokaler Ischämie bei der Ratte, denen eine wesentliche pathogenetische Bedeutung beim Schlaganfall zugeschrieben wird. Dabei wird detailliert die zeitliche und topographische Dynamik dieser reversiblen Depolarisationswellen mittels simultaner 16-Kanal-Elektrokortikographie und 16-Kanal-Magnetoencephalographie beschrieben und aufgezeigt, dass Periinfarktdepolarisationen deutlich komplexere Prozesse sind als bisher vermutet

Experiential satisfaction with a wholly online marketing unit

This study examines the relationship between students&rsquo; satisfaction with a core undergraduate marketing unit, preference for online or face-to-face mode of teaching delivery and intent to major in marketing. The core undergraduate marketing unit was offered only in a wholly online mode, although many of the students had experienced traditional face-to-face classes in previous units. The sample was 112 undergraduate students. Findings indicated students&rsquo; preference for face-to-face mode of teaching delivery did not affect satisfaction with the marketing unit, but there was a significant relationship between unit satisfaction and students preference for online mode of teaching delivery. Mode of teaching delivery preferences suggested neither the online or face-to-face mode affected students&rsquo; choice in majoring in the marketing discipline, however, there was a significant relationship between student satisfaction and intent to major in marketing.<br /
