Background: Feedback about intraoperative performance remains a cornerstone of surgical training. Video playback offers one potential method for more effective feedback to surgical residents. More research is needed to better understand this method. This study explores the nature of instructional interactions and feedback in the operating room (OR) and when using video playback during post-operative review in obstetrics and gynecology (OBGYN) training. Method: This case study occurred between September 2016 and February 2017. Three OBGYN residents and five OBGYN supervising surgeons were involved in six laparoscopic cases. Intraoperative and video playback dialogues were recorded and analysed, the former deductively using codes identified from published literature, and the latter both deductively, using the same codes, and inductively, with codes that emerged from the data during analysis. Results: 1090 intraoperative interactions were identified within 376 minutes of dialogue. Most interactions were didactic, instructing the resident how to use an instrument to perform a task. Deductive analysis of postoperative video playback review identified 146 interactions within 155 minutes. While the most common interaction type remained didactic, a teaching component was included more often. It became apparent that deductive analysis using the intraoperative codes did not adequately capture the nature and focus of feedback during video playback. Hermeneutic phenomenological analysis identified more dialogic video playback sessions with more resident-initiated questions and reflection. Conclusions: This study demonstrates that the nature of feedback during video playback is fundamentally different from that in the OR, offering a greater potential for collaborative and improved learning.

The Impact

The Tagueleft basin is geographically located in the northern edges of the Middle High Atlas, which is a geomorphological fragile area. The impact of human activity has accelerated water erosion in this mountains area. This is reflected in dynamic and unstable foothills, a decrease in forests density and degradation in the production of the land. On the other hand, land degradation due to human overexploitation of natural resources has increased land degradation in the area. The interest in the risk of erosion on the foothills in the area under study comes in the context of our contribution to clarify the role of geomatical and geomorphological approaches in explaining and identifying the mechanisms responsible for current foothills dynamism through water erosion and its negative impacts on the environment and local development. The aim of the study was to use the EPM (Erosion Potential Méthod) which is formulated by Slobodan Gavrilovic for erosion in mountainous areas and to test the reliability of its results based on fieldwork and remote sensing data. The results of the erosion assessment and its quantification by applying the coefficient (W) for the theoretical model in the area under study have shown that erosion is very important and it touches on wide areas as it appears through the domain classification of the distribution erosion in Tagueleft basin.

Chapter 5 discusses the capabilities of RIA frameworks in the context of multimedia content support. For this purpose, several alternatives for implementing video playback functionality are presented by using both JavaScript-based RIA frameworks to and non-JavaScript-based RIA frameworks. Examples of JavaScript-based RIA frameworks having multimedia content support are Dojo, jQuery, Prototype, and Mootools. Examples of non-JavaScript-based RIA frameworks are Adobe Flex™, JavaFX™, Silverlight™, and OpenLaszlo. For each case study the mandatory files are mentioned. The chapter also shows a screenshot where video player is displayed and code snippets that were used are presented. Finally, a comparative analysis of video playback support for each framework is presented in terms of video container formats and encoding types.

Practical Implications

The purpose of this study was to examine postgraduate students’ perceptions of assessment feedback. Using the Critical Incident Technique, students enrolled on a taught clinical course were asked for their perceptions of effective and ineffective examples of assessment feedback. The data were analysed using thematic analysis and nine themes emerged that capture perceptions associated with feedback content and feedback process. Students perceived effective feedback if it was specific and clear, using positive tone of language. They expressed a preference for feedback that is delivered in a standardised format, reflecting the grades given, individualised, and when the marking criteria is explicit and enables dialogue with the marker. Students perceived feedback to be ineffective when it focused on grammatical errors rather than content, when it was provided by anonymous graders and if it was too personal. Timeliness of feedback was also important to participants. Practical implications and suggestions for future research are highlighted in this paper.

Venous Catheterization

Manikins have traditionally been used to train ultrasound-guided Central Venous Catheterization (CVC), but are static in nature and require an expert observer to provide feedback. As a result, virtual simulation and personalized learning has been increasingly adopted in medical education to efficiently provide quantitative feedback. The Dynamic Haptic Robotic Trainer (DHRT) trains surgical residents in CVC needle insertions by simulating various patient profiles and presenting personalized feedback on objective performance. However, no studies have examined the learning gains of the personalized learning feedback or the relation of feedback to what the user is focusing on during the training. Thus, this study was developed to determine the effectiveness of the current personalized learning interface through a long-term investigation with 7 surgical residents. The eye tracking analysis showed that residents spent significantly more time fixated on percent aspiration throughout the study; the more time participants spent looking at the Number of Insertions, Percent Aspiration and the Angle of Insertion on the DHRT GUI, the better they performed on subsequent trials on the DHRT system.

Abstract. Shallow snowpack conditions, which occur throughout the year in many regions as well as during accumulation and ablation periods in all regions, are important in water resources, agriculture, ecosystems, and winter recreation. Terrestrial and airborne (manned and unmanned) laser scanning and structure from motion (SfM) techniques have emerged as viable methods to map snow depths. Lidar on an unmanned aerial vehicle is also a potential method to observe field and slope scale variations of shallow snowpacks. This paper describes an unmanned aerial lidar system, which uses commercially available components, for snow depth mapping on the landscape scale. The system was assessed in a mixed deciduous and coniferous forest and open field for a shallow snowpack (

This article draws on research conducted in a mandatory, first-year calculus course at the Norwegian University of Science and Technology. By the turn of the century concerns were expressed over high failure rates in calculus, and action was called for to remedy the situation. In the years to come, various measures were introduced, though rather scattered and unsystematic. From 2013 onwards development initiatives in the course became more systematic, ensued by expectations of improved learning outcomes. This study draws on data collected by identical surveys conducted four years apart with a view to similarities and differences in attitudes and behaviours. Contrary to expectations, observed changes turned out to be marginal, if not totally missing, which in turn motivated the search for explanations to design more productive strategies.
