Abstract:

Purpose The purpose of this paper is to develop videographic methods for the study of alternative entrepreneurship, with a theoretical focus on “ethical uncertainties”, exemplified in this paper by the exploration of evolving actions and unpredictable outcomes in a specific case, the Hungarian company Prezi. Design/methodology/approach By first situating Prezi’s alternative entrepreneurship in the turbulent Hungarian political context and situation for the Roma population, this study presents how the methodological foundations of organizational videography have affirmed aesthetic immersion, which is of particular use for the study of ethical uncertainty. Findings Following a methodological exploration of the specific research design and ethnographic reflections on three ways in which ethical uncertainties arise, this study discusses the videographic possibilities to study something as elusive as ethical uncertainty and its link to alternative futures. Originality/value The political context in Hungary poses many challenges for organizations that attempt to “do good” and create alternative futures. This paper explains how this political context permeates Prezi’s entrepreneurship and research thereof, by highlighting “ethical uncertainty”. The combined contribution (paper and videography) invites the reader to think differently about the authority of research, become a viewer and reflect on their own experiences of ethical uncertainty in alternative entrepreneurship.

Abstract:

This companion essay contributes to video-based organizational research by critically assessing conventional representational modes of videographic practice and conceptualizing an ‘expressive’ ontology for videographic research. We offer an image of thought that foregrounds the creative and powerfully affective potential of both videographic work and spectatorship. To advance this perspective and to inspire future research, we present our videography (length 30 minutes) that integrates various ‘expressive’ elements in montage form. We use the film to scrutinize the potential of video-based research and several methodological considerations tied to it. In doing so, we argue that video-based organizing of research activities can be seen as ‘monstrous’, an entire emergent mode of aesthetic storytelling that comes into being not in ‘capturing’ or ‘recording’, but rather as an affective production of potentialities.

Abstract:

Along with the changing times and by utilizing the latest technological sophistication videography can be enjoyed in various ways and any variety of formats offered by technology experts in the world.There are currently 2 types of videos are available, namely analog and digital.A videographer categorized or categorize themselves into two, namely the amateur videographer and professional videographer.Amateur or professional, in fact is only the term and sheer status. Unfortunately, it seems there is a presumption of amateur videographer if the result is definitely not good.And because the feel just amateurs, someone feel legitimate only if the video footage is not good.Instead, there is a presumption that a professional videographer can certainly produce good images.

Abstract:

A public park adjacent to an inner-city preschool invites children and their teacher into new encounters with the world, literacy and themselves. The park and preschool are situated in the inner-city of Johannesburg, South Africa. In this article, the researcher performs as mutated-modest-witness of events that unfold in lively materialdiscursive encounters between children, grass, friendship, a pen, cement table, sand, sticks, the alphabet and daylight. The agential realism of Karen Barad and the nomadic thinking of Deleuze and Guattari offer ways of re-imagining ‘the child in the park’. Diffracting with repeated viewings of video clips the researcher finds that forward and reverse movement and stops in different moments throughout repeated viewings of the same video footage produces different and new ‘stories’ about the events and the children involved. Conceptions of ‘child’ as literacy learner and of researcher-as-writer mutate through this diffraction which instantiates a non-representational videography practice.

Abstract:

Abstract Much Linguistic Landscape scholarship relies on visual data collection, primarily the use of still photography; however, the field has yet to address the theoretical underpinning of such visual and spatial representation. Furthermore, digital video is currently as easy to capture and share as digital photographs were when Linguistic Landscape studies first became prominent in the early 2000s. With these two points in mind, this article first grounds the documentation and analysis of the Linguistic Landscape in a theory of visual representation; it then provides a framework for videographic methodologies drawing on recent work in the related fields of anthropology and cultural geography. An example study utilizing non-participatory videography is summarized in which digital video recordings were used to capture and convey the Linguistic Landscape.

Abstract:

The purpose of this article is to critically examine videography in the repertoire of visual approaches and delineate a positioning that would be distinctive, inspiring and daring. Notably, we advocate for alternative video-based approaches that expand the field beyond the dominant ‘representational mode’ by embracing the evocative power of video, and it is only in this way that videographic research could emerge into a self-standing research method without falling under other representational orders of analysis such as being read ‘like text’ or frozen into photographic ‘stills’. In so doing, we develop an image of thought of consumer videographies, where the affective forces of video are harnessed towards ‘theorizing’ in an emergent rather than descriptive form.

Abstract:

This article proposes a protocol for the videographic method in marketing research. Its aim is to develop the toolbox available to researchers by outlining how academic videography can be used and by identifying the challenges and opportunities inherent in such an approach. Providing researchers with a concrete guide in this way is also a response to the calls for more widespread use of this method in the academic community. The article presents both the application and an evaluation of the videographic method through four successive phases: pre-production, production, post-production and dissemination. This protocol is based on an analysis of the origins of videographic research – primarily North American. This is complemented by an analysis of the corpus of French-language productions presented at national and international conferences, with the aim of providing a broad and non-ethnocentric vision so as to specify the methodological process and the various choices involved, thereby contributing to the development of creative and innovative studies.

Abstract:

Airborne videographic remote sensing is a relatively recent technology thatcan provide inexpensive and high-spatial-resolution imagery for forestmanagement. This paper presents a methodology that allows videographic data tobe modelled to predict habitat complexity in eucalypt forests.Within the eucalypt forests of south-eastern New South Wales, plots werelocated on the imagery, and the local variance of the videography within eachplot was computed on the assumption that changes in local variance provided anindication of forest structure, and thus the habitat complexity of the site.The near- infrared (NIR) channel demonstrated the most variation, as thatchannel provided an indication of photosynthetic activity and, as a result,the variation between canopy, understorey, ground cover, soil and shadowprovided a highly variable response in the video imagery. Habitat-complexityscores were used to record forest structure, and the relationship between theNIR variance and field habitat-complexity scores was highly significant(P < 0·001)(r2 = 0·75;n = 29). From this relationship, maps of thehabitat-complexity scores were predicted from the videography at 2-m spatialresolution. The model was extrapolated across a 1 1 km subset of the videodata and field verification showed that the predicted scores correspondedclosely with the field scores.Studies have demonstrated the relationship between habitat-complexity scoresand the distribution and abundance of different mammalian fauna. This methodallows predictions of habitat-complexity scores to be spatially extrapolatedand used to stratify the landscape into regions for both the modelling offaunal habitat and to predict the composition, distribution and abundance ofsome faunal groups across the landscape. Ultimately, the management of foresthabitats for wildlife will depend on the availability of accurate maps of thediversity and extent of habitats over large areas and/or in difficult terrain.

The difficulties faced by the user in selecting photography and videography services are now very limited to access the transmission of his works, and also because a photography and videography have not been computerized to make information and data management scarce. The purpose of the study is to develop a software by pinching agile ux, asa measure of user satisfaction or need to online photography and videography services. The method is the scrum that serves to manage a project more efficiently, and it makes teamwork more effective and focused. The results of this study were developing a software that functioned asa function, from providers and users as well as photography and videography services, so they became more efficient and the published works became more optimized. Testing results using black box testing that test for functionality and required specifications. Applications made to help sell products and promote shops in these materials, so that all are more organized and more effective in the system are washed down. The application has not been entirely feasible, as development in the system is still required.

Abstract:

Abstract BACKGROUND AND IMPORTANCE: Indocyanine green (ICG) fluorescence videography has been recently applied to the neurosurgical field, mostly in the management of cerebral aneurysms, but has had limited description in the subspecialty of spine or oncological neurosurgery. We describe a novel application of this previously defined surgical tool to assist in the resection of a residual spinal cord hemangioblastoma. CLINICAL PRESENTATION: Our patient is a 49-year-old woman with a residual symptomatic cervical hemangioblastoma that was previously embolized and resected at another institution. After initial symptomatic improvement, she returned with progressive symptoms, increasing radiographic spinal cord edema, and a residual lesion at the level of C1. We resected the remaining tumor with the adjuvant use of ICG fluorescence videography. Intraoperative injection of ICG clearly identified a component of the tumor underlying adhesive, opaque arachnoid that was not visualized by direct microscopy. Immediate postresection ICG videography suggested a complete resection was achieved which was later corroborated by postoperative magnetic resonance imaging. CONCLUSION: The adjuvant use of ICG videography is a useful surgical tool that permits greater visualization of the complete extent of the lesion, particularly in managing recurrent or residual lesions obscured by adhesions.

Abstract:

Object Indocyanine green (ICG) videography is commonly used in the neurosurgical field for minimally invasive neurosurgery. The aim of this study was to evaluate a new intraoperative imaging modality by performing transdural ICG videography during surgery for meningiomas. Methods Between March 2011 and April 2012, 10 patients with meningiomas received intravenous injection of 12.5 mg ICG just prior to dural opening. The cases comprised 8 convexity meningiomas and 2 foramen magnum meningiomas. Efficacy of the transdural ICG videography was assessed in terms of the tumor volume, the circulation time from the first appearance of the vessel to the appearance of the venous sinus, the tendency to bleed, and the discrimination of the venous sinus. Results The mean tumor volume was 71.6 ± 87.9 ml (the mean is expressed ± SD throughout). The cortical arteries, veins, and the venous sinus were identified by the ICG videography transdurally. The projection of the meningiomas was identified by a shadow (which the authors call the eclipse sign). Total eclipse signs were obtained in 8 cases and partial eclipse signs were obtained in 2 cases; tumor volume in the latter was more than 200 ml. In 5 of 10 cases the adjacent venous sinuses were exposed and were successfully visualized by ICG videography in 5.92 ± 1.05 seconds from the first appearance of the vessel. In 5 of 10 cases the total and the partial eclipse signs were diminished in 3.46 ± 1.31 seconds. The diminishment of the total and the partial eclipse sign was earlier than the visualization of the venous sinus (p = 0.011, t-test), revealing bleeding from the tumor that was observed until coagulation of the feeding arteries from the intracranial arteries. Conclusions Prior to opening of the dura mater, transdural ICG videography was used successfully to visualize the dural attachment of meningiomas and the venous sinus, resulting in safe and appropriate dural opening. The diminishment of the total and partial eclipse signs may represent significant feeding from the intracranial arteries and a tendency to bleed during resection.

Abstract:

Purpose – The purpose of this paper is to present videography as a rising method available for academics. Visuals are increasingly omnipresent in the modern society. As they become easy to create and use, videos are no longer only for ethnographers and specialist researchers. Design/methodology/approach – In the society of “user-content generation,” visual data are incredibly important, original, and powerful sources providing researchers with opportunities to inventively make their results more resonant and more broadly accessible. Findings – Moreover, videography offers the opportunity for researchers to become a kind of artist since they become visual producers. Practical implications – This paper offers concrete advices for researchers who want to to become visual producers. Social implications – Researchers have to make their results more resonant and more broadly accessable. Originality/value – Videography is a new way (an artistic one) to present results of research.

Abstract:

Videography is the most practical and effective method of documenting and teaching ENT endoscopy. Videography allows: (1) documentation of anatomy, physiology and pathology of deep structures of the ear, nose and throat; (2) teaching of delicate surgical procedures such as functional endoscopic sinus surgery (FESS), laryngeal surgery, and other endoscopic procedures; (3) instantaneous production of high quality hard copies of video images for teaching and patient records; (4) instant replay and repeated viewing by a slow motion or frame-by-frame analysis; (5) simultaneous viewing by a small or large audience; and (6) image digitalization for storage in the computer for later analysis. The author describes the value of videography in ENT endoscopy, namely video-otoscopy, video rhinoscopy and video-laryngoscopy. The use of video in endoscopy will continue to play a vital role in Continuing Medical Education (CME).

Abstract:

A 19-month-old child was gradually suffering from gait disturbance and was referred by his pediatrician to the authors' institution. Spinal MRI showed Gd-enhanced spinal cord tumor and congestive myelopathy. Intraoperatively the lesion was seen to be a hemangioblastoma. Because discrimination of the arterialized draining veins from the feeding arteries was difficult, indocyanine green videography was conducted to differentiate them. Real-time evaluation by FLOW 800 revealed that the slope of the average signal intensity in the feeding artery was steeper than that of the arterialized veins. The tumor was successfully resected, and postoperative indocyanine green videography showed total removal of the tumor as a signal-negative region; the circulation time between the feeding artery and the main draining vein was prolonged from 2.5 to 5.5 seconds. Indocyanine green videography and real-time evaluation by FLOW 800 were objective and effective for the excision of a tumor retaining the arteriovenous shunt. The patient recovered from congestive myelopathy and gait disturbance.

Abstract:

The relationship between forest structure or habitat complexity and distribution and abundance has been demonstrated for a variety of mammalian species in the southern forests of Australia. Recently, studies that utilise airborne videography data have predicted forest structure across forested landscapes. This paper unites these two fields of research. Existing models of species abundance were applied to spatial estimates of habitat complexity to produce predictions of the distribution and abundance of two small ground-dwelling mammals commonly found in eucalypt forests. The spatial estimates of habitat complexity were extrapolated across the landscape from videography at 2-m spatial resolution on four 1-km 2 study areas. To examine the accuracy of the abundance predictions, trapping grids for the two species were established across a range of abundances. Linear regression showed a strong positive relationship between the predicted distribution and abundance from the videography and the recorded distribution and abundance for the species.

Abstract:

Im vorliegenden Beitrag wird ein videographisches Forschungsdesign vorgestellt und auf das populäre Augmented Reality (AR) Mobile Game Pokémon GO angewendet. Dabei wird herausgearbeitet, wie ein mediatisiertes Phänomen methodisch untersucht werden kann, welches sich vor allem durch seine kleinteiligen, an die Spiel- und/oder Alltagsrealität gerichteten Interaktionsformen sowie seine flüchtige Spielpraxis auszeichnet. Es wird eine phänomenologische und dramatologische Perspektive eingenommen, um eben diese methodischen Kernprobleme herauszuarbeiten. Das Datenmaterial, das mit einer mobilen GoPro Kamera erhoben wurde, wird mit Hilfe der (sequenzanalytischen) Rahmenanalyse (Goffman 1977) ausgewertet. Bei der Vorstellung der Ergebnisse kommt das Konzept der synthetischen Situation (Knorr-Cetina 2009) zur Anwendung und wird um den Aspekt des mediatisierten Alltagsraumes und seiner interaktiven und körperlich-performativen Herstellung erweitert.

Abstract:

Previous methods for detecting the flashing behavior of fireflies were using either a photomultiplier tube, a stopwatch, or videography. Limitations and problems are associated with these methods, i.e., errors in data collection and analysis, and it is time-consuming. This study aims to applied a computer vision approach to reduce the time of data collection and analysis as compared to the videography methods by illuminance calculation, time of flash occurrence, and optimize the position coordinate automatically and tracking each firefly individually. The Validation of the approach was performed by comparing the flashing data of male fireflies, Sclerotia aquatilis that was obtained from the analysis of the behavioral video. The pulse duration, flash interval, and flash patterns of S. aquatilis were similar to a reference study. The accuracy ratio of the tracking algorithm for tracking multiple fireflies was 0.94. The time consumption required to analyze the video decreased up to 96.82% and 76.91% when compared with videography and the stopwatch method, respectively. Therefore, this program could be employed as an alternative technique for the study of fireflies flashing behavior.

Abstract:

The purpose of the current study was to assess the validity and reliability of measures obtained by a 3-axis commercial accelerometer during weightlifting movements in comparison with kinematic data derived from the 3D videography. Kinematic data from 3D videography were obtained from 11 track & field throwers performing 3 trials each one at different loads in power snatch, power clean and jerk from the rack. The results showed that the accelerometer measures were highly correlated with derived acceleration data from 3D videography data in the vertical plane (Z axis) taking up to the pull phase (including first pull, transition and second pull) for power snatch and power clean and up to the highest point of the bar path before the catch position (including dip, drive and split phases) for jerk from the rack. On the basis of these results, this device was proven to be valid and reliable on Z axis on the weightlifting movements studied. Thus, this system may be a useful and easy to handle tool to measure acceleration during real-time training sessions.

Abstract:

Investigation of nighttime motor vehicle collisions represents one of the most challenging aspects of collision reconstruction. Nighttime collisions with motorcycles, pedestrians, cyclists, skateboarders, or wildlife will often require the investigator to assess the visibility of the struck object from the driver perspective at the time of the collision. Since lighting conditions, weather conditions and traffic conditions are continually changing, the ability of the investigator to create a perfect re-enactment is, by definition, not usually possible. As such, the investigator must make use of nighttime visibility assessment techniques to best reproduce the conditions at the time and correctly account for all other factors that are not in the investigator’s control. The goal of this panel discussion session is to share the combined experience and knowledge of the panelists with the audience regarding the tried-and-tested best practice techniques and tips of conducting nighttime collision re-enactments.
