The article engages with trans male video blogs on YouTube, framing them as living archives that offer unique opportunities to access and share embodied trans knowledges—which have previously been limited or inaccessible—such as information about and visual accounts of medical transitioning processes. It is argued that archiving one's transition works through a kind of performative documentation, partly documenting and partly instantiating the transformation by tracking and tracing the bodily changes. Testosterone figures as the transformative technology, while the upper body becomes the privileged site of self-fashioning. YouTube hereby offers an alternative and empowering archive of how trans male bodies could look, while its cumulative effects also play a significant role in determining how they should look.

This chapter discusses multimodal approaches to the study of linguistics, and of representation and communication more generally. It draws attention to the range of different modes that people use to make meaning beyond language –such as speech, gesture, gaze, image and writing – and in doing so, offers new ways of analysing language. The chapter addresses two key questions. First, how can all these modes be handled theoretically? What are ‘modes’? How do people use them? Second, how can all these modes be handled analytically? What are the methodological implications if one or more modes are excluded from the analysis? The chapter fi rst highlights the ways in which multimodality is taken up in social linguistic research. It then describes a social semiotic approach to multimodality. The steps taken in such an approach are described and exemplified with case studies of classroom interaction and textbooks. It concludes with a discussion of the potentials and constraints of multimodal analysis.

This paper seeks to (re)think what constitutes records within an ethnographic archive by making visible the challenges that our external IE team faced as we entered the records archived by the internal IE team that we were invited to support in the documentation and analysis of a developing Instructional Development project. Although both teams shared a common conceptual logic-of-inquiry – Interactional Ethnography – It became evident that there were limits to certainty (Green & Baker 2007) that led us to (re)examine why some particular records were archived and what they were records of.

The massacre of almost 50 Maidan protesters on February 20, 2014 was a turning point in Ukrainian politics and a tipping point in the conflict between the West and Russia over Ukraine. This mass killing of the protesters and the mass shooting of the police that preceded it led to the overthrow of the pro-Russian government of Viktor Yanukovych and gave a start to a civil war in Donbas in Eastern Ukraine, Russian military intervention in Crimea and Donbas, and an international conflict between the West and Russia over Ukraine. A conclusion promoted by the post-Yanukovych governments and the media in Ukraine that the massacre was perpetrated by government snipers and special police units on a Yanukovych order has been nearly universally accepted by the Western governments, the media, and many scholars. The Ukrainian government investigation identified members of the special company of Berkut as responsible for killings of the absolute majority of the protesters, but did not release any evidence in support, with the exception of videos of the massacre.
              The question is which side organized the “snipers’ massacre.” This paper is the first academic study of this crucial case of the mass killing. It uses a theory of rational choice and a Weberian theory of instrumental rationality to examine actions of major actors both from the Yanukovych government, specifically various police and security forces, and the Maidan opposition, specifically its far right and oligarchic elements, during the massacre.
          The paper analyzes a large amount of evidence from different publicly available sources concerning this massacre and killings of specifics protesters. Qualitative content analysis includes the following data: about 1,500 videos and recordings of live internet and TV broadcasts from mass media and social media in different countries(some 150 gigabytes), news reports and social media posts by more than 100 journalists covering the massacre from Kyiv, some 5,000 photos, and nearly 30 gigabytes of publicly available radio intercepts of snipers and commanders from the special Alfa unit of the Security Service of Ukraine and Internal Troops, and Maidan massacre trial recordings. This study also employs field research on site of the massacre, eyewitness reports by both Maidan protesters and government special units commanders, statements by both former and current government officials, estimates of approximate ballistic trajectories, bullets and weapons used, and types of wounds among both protesters and the police. This study establishes a precise timeline for various events of the massacre, the locations of both the shooters and the government snipers, and the specific timeline and locations of nearly 50 protesters’ deaths. It also briefly analyzes other major cases of violence during and after the “Euromaidan.” This study includes two video appendixes.
            This academic investigation concludes that the massacre was a false flag operation, which was rationally planned and carried out with a goal of the overthrow of the government and seizure of power. It found various evidence of the involvement of an alliance of the far right organizations, specifically the Right Sector and Svoboda, and oligarchic parties, such as Fatherland. Concealed shooters and spotters were located in at least 20 Maidan-controlled buildings or areas. The various evidence that the protesters were killed from these locations include some 70 testimonies, primarily by Maidan protesters, several videos of “snipers” targeting protesters from these buildings, comparisons of positions of the specific protesters at the time of their killing and their entry wounds, and bullet impact signs. The study uncovered various videos and photos of armed Maidan “snipers” and spotters in many of these buildings. The paper presents implications of these findings for understanding the nature of the change of the government in Ukraine, the civil war in Donbas, Russian military intervention in Crimea and Donbas, and an international conflict between the West and Russia over Ukraine.

The supervision of people in special circumstances, having as their purpose detecting risk situations, is an area which has many applications. In this context we are interested, in this paper, the problems of driver drowsiness detection based on video analysis. We describe a new approach to detect reduced alertness automatically, to prevent the driver. Unlike many other works, our noninvasively approach is based only on the analysis of geometric features captured form faces video sequence without any electronics elements related to human.

In the course of election campaigns politicians and political parties try their best to highlight their most favored topics that would help them draw public attention and increase people’s regard for specific political figures. In contrast to the positive communication content announced during an election campaign, candidates sometimes choose negative messages that focus on their opponents’ weaknesses (real or imagined) rather than their own strengths. The goal of this research is to identify the forms and means of negative communication used in political video advertisements during Lithuanian parliamentary election of 2016. To achieve our goal, we analyze the political video advertisements that were categorized as negative communication. We categorize and analyze those advertisements by using concepts of forms of negativity and targets of negativity. Our findings suggest that negative communication is being used by Lithuanian political organizations, but it is the positive one that...

The study investigated variant and invariant physics teaching patterns across time and topics. It is assumed that the analysis perspective is decisive for identifying variant and invariant teaching patterns. Therefore, we focused on three perspectives:

Illumination invariance remains the most researched, yet the most challenging aspect of automatic face recognition. In this paper we investigate the discriminative power of colour-based invariants in the presence of large illumination changes between training and test data, when appearance changes due to cast shadows and non-Lambertian effects are significant. Specifically, there are three main contributions: (i) we employ a more sophisticated photometric model of the camera and show how its parameters can be estimated, (ii) we derive several novel colour-based face invariants, and (iii) on a large database of video sequences we examine and evaluate the largest number of colour-based representations in the literature. Our results suggest that colour invariants do have a substantial discriminative power which may increase the robustness and accuracy of recognition from low resolution images.

Despite the growing sociological interest in the object, and the longstanding tradition in the humanities and social sciences with the creation of art and artefacts, there is relatively little research concerned with how people in ordinary day to day circumstances explore and respond to exhibits in museums and galleries. In this paper, we address the conduct and interaction of visitors to museums and galleries and consider how they examine and experience objects and artefacts in collaboration with each other. In particular, we address the ways in which one participant shapes, through gesture and talk, how those they are with look at and respond to exhibits.

This research analyzes how children from 0 to 12 years are developing their practices in the network, focusing on the analysis of the production of videos for YouTube, from the case study of the channel Planeta das Gêmeas. The article articulates the changes of the practices from the convergences of Jenkins (2009) and Espinosa (2016), taking in to account the notion of digital natives of Prensky (2001) and Castro (2002) of current childhood. A study that infers a performance analysis under professional aspects

A fast and simple method for content based retrieval using the DC-pictures of H.264 coded video without full decompression is presented. Compressed domain retrieval is very desirable for content analysis and retrieval of compressed image and video. Even though, DCpictures are among the most widely used compressed domain indexing and retrieval methods in pre H.264 coded videos, they are not generally used in the H.264 coded video. This is due to two main facts, first, the I-Frame in the H.264 standard are spatially predicatively coded and second, the H.264 standard employs Integer Discrete Cosine Transform. In this paper we have applied color histogram indexing method on the DC-pictures derived from H.264 coded I-frames. Since the method is based on independent I-frame coded pictures, it can be used either for video analysis of H.264 coded videos, or image retrieval of the I-frame based coded images such as advanced image coding. The retrieval performance of the proposed algorithm is compared with that the fully decoded images. Simulation results indicate that the performance of the proposed method is very close to the fully decompressed image systems. Moreover the proposed method has much lower computational load.

Lernprozesse bei problemorientierten Lernaufgaben mit und ohne Experimentieranleitung
Der Einbezug von Vorwissen im inquiry based learning in der Grundschule

Schon in der Grundschule sollen Kinder mit naturwissenschaftlichem Lernen Erfahrungen sammeln und Kompetenzen aufbauen können. Dabei steht handelnd-entdeckendes Lernen im Vordergrund. Bei der Entwicklung von Lernaufgaben stellt sich die Frage, inwieweit eine Handlungsanleitung nötig und hilfreich ist, damit Grundschülerinnen und Grundschü-ler eine naturwissenschaftliche problemorientierte Lernaufgabe lösen können. Im folgen-den Beitrag werden zwei Versionen einer problemorientierten Lernaufgabe zum Thema Klimawandel eingesetzt: eine problemorientierte Lernaufgabe ohne Handlungsanleitung, sowie die gleiche problemorientierte Lernaufgabe, jedoch mit Handlungsanleitung. Die Handlungsanleitung folgt dem häufig verwendeten Schema mit Leitfragen und schrittwei-ser Führung für das Experimentieren: eine Vermutung formulieren, den Versuch aufstellen, Daten erheben und auswerten, Vergleich der Ergebnisse mit der Vermutung und Übertragung der Ergebnisse auf das Problem. Zwanzig Zweiergruppen von Kindern im Alter von 9 bis 14 Jahren werden bei der Lösung dieser Arbeit videografiert. In der vorlie-genden Analyse wird darauf fokussiert, welche Arten von Vorwissen die Schüler/innen in den Dialog zur Problemlösung einbringen und ob sich die Aktivierung des Vorwissens in den beiden Bedingungen unterscheidet.

Background Institutions, government departments, and healthcare professionals engage in social media because it facilitates reaching a large number of people simultaneously. YouTube provides a platform whereby anyone can upload videos and gain feedback on their content from other users. There are many YouTube videos related to health and science, and many people search YouTube for health-related information. YouTube has been acknowledged as a key public information source in recent crises caused by Zika, H1N1, swine flu, and most recently, COVID-19. Methods YouTube videos were collected from the YouTube Application Programming Interface (API) using the search terms COVID-19, coronavirus, COVID19, and corona. The search was conducted on April 4 and 5, 2020.The initial search found a total of 1084 videos. The second step involved identifying and verifying the videos for their relationship to COVID-19 information and excluding videos that did not relate to COVID-19 or were in a languag...

Investing on Facebook and Google online advertising is essential to increase sales and the organization brand awareness. However, sometimes, it’s difficult to decide which is the right budget for each platform, because there are so many variables that can impact in the correct resources allocation.
That's why, it's important to know if Facebook can get more results than Google, and the impact of each platform on other traffic sources. But also, which of the ecosystems allows to get more brand awareness at a lower cost.
The online store www.vascomarques.digital was analysed, and data collected for a period of nine months through Google Analytics, in order to confirm which platform generated more sales and more brand awareness.
The results show that Facebook ecosystem brought more sales and more brand awareness than Google, especially if compared to Google search ads. The data collected also indicate that Facebook is an important factor on sales through other traffic sources.

We present a novel algorithm for detection of certain types of unusual events. The algorithm is based on multiple local monitors which collect low-level statistics. Each local monitor produces an alert if its current measurement is unusual and these alerts are integrated to a final decision regarding the existence of an unusual event. Our algorithm satisfies a set of requirements that are critical for successful deployment of any large-scale surveillance system. In particular, it requires a minimal setup (taking only a few minutes) and is fully automatic afterwards. Since it is not based on objects' tracks, it is robust and works well in crowded scenes where tracking-based algorithms are likely to fail. The algorithm is effective as soon as sufficient low-level observations representing the routine activity have been collected, which usually happens after a few minutes. Our algorithm runs in real-time. It was tested on a variety of real-life crowded scenes. A ground-truth was extracted for these scenes, with respect to which detection and false-alarm rates are reported.

Dynamically changing background ("dynamic background") still presents a great challenge to many motion-based video surveillance systems. In the context of event detection, it is a major source of false alarms. There is a strong need from the security industry either to detect and suppress these false alarms, or dampen the effects of background changes, so as to increase the sensitivity to meaningful events of interest. In this paper, we restrict our focus to one of the most common causes of dynamic background changes: that of swaying tree branches and their shadows under windy conditions. Considering the ultimate goal in a video analytics pipeline, we formulate a new dynamic background detection problem as a signal processing alternative to the previously described but unreliable computer vision-based approaches. Within this new framework, we directly reduce the number of false alarms by testing if the detected events are due to characteristic background motions. In addition, we introduce a new dataset suitable for the evaluation of dynamic background detection. It consists of real-world events detected by a commercial surveillance system from two static surveillance cameras. The research question we address is whether dynamic background can be detected reliably and efficiently using simple motion features and in the presence of similar but meaningful events such as loitering. Inspired by the tree aerodynamics theory, we propose a novel method named local variation persistence (LVP), that captures the key characteristics of swaying motions. The method is posed as a convex optimization problem whose variable is the local variation. We derive a computationally efficient algorithm for solving the optimization problem, the solution of which is then used to form a powerful detection statistic. On our newly collected dataset, we demonstrate that the proposed LVP achieves excellent detection results and outperforms the best alternative adapted from existing art in the dynamic background literature.

Creative choice is an individual act. As in other fields such as filmmaking, dance creation is based on a cognItive dualism that considers the choreographer as the creative decision-maker, while the dancer is objectified. The dancer’s body is an instrument for exploration of the choreographer’s imagery. We claim that the products of creativity are minute but crucial modifications of transitory stages of a dance rehearsal. On the one hand, attention is given to a dance company as a distributed cognitive system. The choreographer communicates in diverse modalities, which carry specific information, physical as well as symbolic. Through the analysis of an audiovisual and cognitive ethnography with ELAN software we find differences in decision-making patterns across multimodal instructions. On the other hand, we apply Social Network Analysis and UCINET software as a methodological innovation in order to formalize data from observed rehearsal settings. In all, the choice of modalities in the chorographical instruction shapes movement production, which is based on dyads, triads and other forms of creative interaction.

We examine the types of emergent language eighth grade students in rural Maine middle schools use when they discuss energy in their first experiences with Project-Based Inquiry Science: Energy, a research-based curriculum that uses a specific language for talking about energy. By comparative analysis of the language used by the curriculum materials to students' language, we find that students' talk is at times more aligned with a Stores and Transfer model of energy than the Forms model supported by the curriculum.

In this paper, we explore some of the applications of computer vision to sports analytics. Sport analytics deals with understanding and discovering patterns from a corpus of sports data. Analysing such data provides important performance metrics for the players, for instance in soccer matches, that could be useful for estimating their fitness and strengths. Team level statistics can also be estimated from such analysis. This paper mainly focuses on some the challenges and opportunities presented by sport video analysis in computer vision. Specifically, we use our multi-camera setup as a framework to discuss some of the real-life challenges for machine learning algorithms.

In this working paper we will present a research methodology for describing and comparing corpus of video productions diffused and shared on social media platforms (here: You Tube). The objective of this research is: 1. to study and interpret the cultural representations of the figure of the migrant/immigrant and refugee in virtual local and global communities viewing, commenting and remediating (rewriting) such video productions and 2. to interpret these cultural representations as belonging to a diversity of (new) folk cultures offering especially people from the younger generations (the so-called Millennials and Post-Millennials also sometimes called Homelanders) an epistemic framework for thematizing and narrating the (social) Other (here: the migrant, the immigrant and the refugee). This paper constitutes the principal support of our course entitled “Cultural visions of (im)migrants and (im)migration in the digital social mediasphere”. This course is part of the EMICC (European Master in InterCultural Communication) program offered by a network of European universities and coordinated by the Università della Svizzera italiana (USI) in Lugano . The methodology and results discussed in this paper will also be presented in the First Eurocampus Conference “Advances in Intercultural Communication” in January 2018 and hosted by the Universidade Aberta in Coimbra (Portugal). Finally, we would also like to stress that this is a first uncorrected version of a research article to be published in the Cambridge Handbook of Intercultural Communication, edited by Guido Rings and Sebastian Rasinger (expected publication date: end of 2018/first half of 2019).

With impunity, millions of players traverse the fictional landscapes of video games every day. Video Game Narrative and Criticism treats gameplay as the player's own psychological experience where fears, desires, and anxieties are projected onto the game's fictional world. By exploring the structural peculiarities of storytelling in video games, the book develops a critical paradigm that explains the meaning of gameplay as self-discovery. The player-response criticism considers the nature of game fiction by centralizing the player in the analysis. This interpretative model is not a rigorous analytical toolbox. Rather, it responds flexibly to the essential fluidity, temporality, and openness of a player's own experience in an intelligent fictional world.

Pulp's so-called working-class anthem "Common People" positions itself in a twofold way towards the concept of authenticity, namely constructing and deconstructing it at the same time. Ths paper examines the different versions of "Common People", including the official music video, two live recordings, and of course the lyrics.

The uncontrolled dissemination of User-Generated Content (UGC) through social media and video platforms raises increasing concerns about the intentional or unintentional spread of misleading information. As a result, people who are turning to the Internet for their daily news, need tools that help them distinguish between reliable and unreliable content. Here we present the Context Aggregation and Analysis tool, with the aim to facilitate the investigation of the veracity of User-Generated videos (UGVs). The tool collects and calculates a set of verification cues based on the video context, that is the information surrounding the video rather than the video itself, and then creates a verification report. The cues include information about the video and user that posted it, as well as the activity of other users surrounding it (what we call “wisdom of the crowd”), cross-checking with previous cases of fakes (“wisdom of the past”), and employing machine learning systems trained on pas...

Il mio progetto di ricerca intende prendere in analisi alcuni prodotti multimediali (videogames, giochi di ruolo, avventure grafiche) che riprendono opere significative della letteratura italiana, o anche rielaborano motivi, tematiche, ambienti legati alla nostra tradizione culturale, comprendendo di essa ulteriori declinazioni popolari e folkloriche. L’obiettivo principale del presente lavoro è definire, al di là delle differenze formali e contenutistiche tra fonte e riscrittura, se e in che misura siano mantenute significazioni del testo di partenza (L. Hutcheon, A Theory of Adaption, 2006),  quali funzioni rivestano modifiche ed adeguamenti, come si configuri il ruolo del lettore/giocatore nelle rielaborazioni.
Primo in ordine cronologico è il gioco di ruolo Orlando Furioso, di Andrea Angiolino e Gianluca Meluzzi, del quale esiste una prima versione didattica per le scuole, edita nel 1993, e una seconda ampliata, pubblicata nel 2002 da Rose § Poison e arricchita da una guida ai luoghi del poema. L’ambiente ludico riprende di fatto l’intero ciclo carolingio e bretone, integrando le vicende ariostesche con l’Orlando Innamorato del Boiardo. I valori cavallereschi, riassunti in Agilità, Forza Dialettica, Concentrazione, Vitalità, Eroismo, sono a disposizione dei giocatori, mentre il narratore crea le trame utilizzando le conoscenze – personaggi reali, figure mitologiche, oggetti magici e non -  fornite dal testo, che si avvale delle illustrazioni di Gustave Doré. Presenza del magico e dell’avventuroso, tensione fra casualità dell’esistenza (i giocatori agiscono anche tirando i dadi) ed equilibrio, già elementi fondanti del poema, diventano componenti del gioco, da utilizzare per immergersi da protagonisti in un mondo al quale possono essere aggregate narrazioni ‘esterne’, mitologiche e folkloriche, come già in parte avviene nell’opera originaria. L’interazione fra giocatori determina inoltre una campitura architettonica complessa, con rimandi, entralacement, ritorni, affine a quella ariostesca; la coppia giocatore/narratore quindi rielabora, ed elabora,  questo e altri infiniti poemi, rendendo il  poema di Ariosto testo ‘scrivibile’,  secondo la definizione di Roland Barthes in S/Z (1970) : non più soltanto un prodotto ‘leggibile’, chiuso, ma connesso ad altri testi e attivatore di ulteriori significati nella cultura contemporanea.
Il secondo prodotto che intendo analizzare è il videogioco Dante’s Inferno, distribuito da Electronic Arts nel 2010; screenwriter Brandon Auman. La trama, che presenta un Dante crociato diretto all’Inferno per salvare Beatrice rapita da Lucifero, è stata stigmatizzata come irrispettoso ‘stravolgimento’ del testo originario (Barolini, Entertainment Weekly, 2010). In realtà, se il gioco sfronda la fonte letteraria di ogni complessità, esaltando il momento interattivo fra il protagonista e le figure infernali come combattimento videoludico, il senso del viaggio dantesco come percorso spirituale viene esteriorizzato ma non stravolto: Dante si confronta effettivamente con i propri peccati, incarnati nei demoni che incontra nei diversi gironi, e l’aumento della violenza e pericolosità degli scontri corrisponde alla profondità della colpa da espiare.  La stessa modalità di gioco, che consente al fruitore di vivere in prima persona la discesa agli Inferi, sembra rispondere all’intento dantesco di allargare l’esperienza personale ( “mi ritrovai”)  ad ogni individuo ed a tutta l’umanità (“nostra vita”).
In ogni caso, nonostante le infedeltà, il videogioco ha il merito di rendere concreto ed alla portata di un vastissimo pubblico il mondo dell’inferno dantesco, grazie ad ambientazioni di alto livello qualitativo, dove suoni, colori, silenzi ricreano in modo efficace l’atmosfera dell’opera originale. Ne è derivata un significativo interesse per l’opera di Dante, soprattutto nei paesi anglosassoni, interesse riscontrabile facilmente sul web, ma non esattamente quantificabile proprio per la vastità del fenomeno: cercando termini collegati a Dante, quali Divine Comedy o simili, sono presenti su Google più di un milione di siti e pagine web.
Il presente progetto, accogliendo i suggerimenti forniti da analoghi lavori di Tison Pugh, Angela Jane Weisl, Denise Ayo, intende quindi stabilire le possibili connessioni fra tradizione dantesca e immaginario contemporaneo, per determinare modalità e limiti di un’attualizzazione che ripensa interamente il Dante della tradizione letteraria.
A conclusione del mio discorso intendo esaminare l’avventura grafica Occultus, cabala mediterranea (2016), sviluppata dal gruppo Sylphe Labs (Luca Alba, Paolo Gallo, Filippo M. Vela). Il gioco presenta una Palermo di primo Novecento, città di intrighi e mostri, esoterica e cabalistica: un anziano antiquario perseguitato da una maledizione di famiglia chiede aiuto al nipote, che dovrà fronteggiare creature soprannaturali, misteri inquietanti, pericolosi gruppi settari quali i Beati Paoli. Il giocatore attraversa luoghi dove la splendida realtà di superficie- antiche strade, piazze, monumenti sono fedelmente riprodotti – nasconde un sottosuolo orrifico, svelato tramite gli enigmi da affrontare per procedere nella dinamica ludica; la matrice culturale è il feuilleton siciliano, da I misteri di Palermo (1852) di Benedetto Naselli, ai Beati Paoli ( 1909/1910) di Luigi Natoli, ma anche la ricerca antropologica di Giuseppe Pitrè, che mostra la perturbante contiguità fra sfera del quotidiano e soprannaturale. Il gioco permette l’esperienza diretta e sensoriale, visiva e auditiva, dei sotterranei palermitani, mostrati nel percorso labirintico dei Qanat, come luogo di miseria, corruzione, terrore; se le trame arcane della vicenda e i destini prefissati dei personaggi si esplicano nell’ambito del fantastico, è adombrata una valenza politica e insieme l’immagine del violento e sopraffattorio potere aristocratico, ampiamente presente nei testi /fonte.
I prodotti multimediali esaminati quindi, per quanto distanti dalle rispettive matrici letterarie, ne rappresentano valide forme di riscrittura, che riattivano i sensi delle opere/fonte inserendole in un circuito di ricezione contemporanea, confermandone altresì lo status di ‘opera aperta’ (Umberto Eco, 1962), tale cioè da permettere l’incontro creativo fra autore e lettore.

Observations of deep-sea homolids are becoming more common, but good-resolution imagery of these crabs in the natural environment is still scarce. Sixteen new in situ observations of Paromola cuvieri from various locations of the Azores Archipelago (Northeast Atlantic) are described here based on video footage collected by two submersible vehicles. Crabs were found on coral gardens and deep-sea sponge aggregations, which are priority habitats of conservation importance under OSPARCOM. Diverse sessile megafauna were recorded (>59 taxa), including sponges, hydroids, corals, brachiopods, crinoids and oysters. Overall, 75% of the crabs were carrying live specimens of sessile invertebrates, mainly sponges and cold-water corals. Object selection shows to be a more complex process than previously thought, in which factors such as morphology, size and weight of objects and also palatability seem to be more important in the process of object selection than their availability.

If the purpose of reflection is to improve teaching, it is essential to understand how video-aided reflection influences teacher change. Yet, there is limited research addressing how video analysis influences the change process. The purpose of this study was to gain an in depth understanding of how video influences the process of teacher change. Teachers in three different teaching environments engaged in semester-long video-reflection groups. Through a descriptive analysis of these meetings, participants' own video-analyses, and individual interviews, six over-arching themes emerged across the different environments that describe the change process. Teachers reported that video encouraged change because it helped them: (a) focus their analysis, (b) see their teaching from a new perspective, (c) trust the feedback they received, (d) feel accountable to change their practice, (e) remember to implement changes, and (f) see their progress. We discuss how these results may help researchers and educators understand how video can be used to encourage teacher improvement.

Better than Best Practice offers a new way of thinking about classroom practice, professional development, and improving teaching and learning. This companion book and website together offer a selection of rich and realistic video-based case studies, context and narrative, step-by-step guidance through key issues, and commentary and debate from a range of expert contributors. Carefully chosen video clips from primary school literacy lessons show real teachers in a variety of often knotty situations: classroom conversations that take unexpected turns; grappling with assessment; managing disagreements, to name a few. The book explores the educational potential of classroom talk and, in particular, the promise and problems of dialogic pedagogy. With an emphasis on the complexity and 'messiness' of teaching, Better than Best Practice considers how to learn from observing and discussing practice in order to develop professional judgment. It offers practical advice on how to organise and facilitate video-based professional development in which teachers share their practice with colleagues in order to learn from one another's challenges, problems, dilemmas and breakthroughs. This exciting new resource argues that critical discussions of practice, which highlight dilemmas instead of prescribing solutions, help to develop and support thoughtful, flexible, and insightful practitioners: an approach that is better than best practice.

Our aim is to provide an understanding of the experience of women with inflammatory bowel disease (IBD) who have made the transition to motherhood. A total of 22 mothers with IBD were recruited from around the United Kingdom. Semi-structured interviews were conducted and analyzed using thematic analysis. The central concept—Blurred Lines—offers a novel frame for understanding the transition to motherhood with IBD through identifying parallels between having IBD and becoming, and being, a mother. Parallels clustered into three main themes: Need for Readiness, Lifestyle Changes, and Monitoring Personal and Physical Development. Hence, women with IBD are in some ways well prepared for the challenges of motherhood even though, as a group, they tend to restrict their reproductive choices. We recommend health professionals initiate conversations about reproduction early and provide a multidisciplinary approach to pregnancy and IBD in which women have confidence that their ongoing treatment will be integrated successfully with their maternity care.

While the increased incidence of serious knee injuries in female athletes is well established, the underlying neuromuscular mechanisms related to the elevated ACL injury rate has yet to be delineated. Video analysis of ACL injury during competitive sports play indicates a common body position associated with non-contact ACL injury; the tibia is externally rotated, the knee is close to full extension, the foot is planted and as the limb is decelerated it collapses into valgus. The purpose of the current prospective study was to evaluate gender differences in quadriceps muscle activation strategies when performing a physically challenging, but reproducible maneuver that mimics the high ACL injury risk position (in the absence of high velocity and high loads). Twenty physically active college-aged subjects (10 male and 10 female) performed multiple sets of the prescribed exercise. EMG recordings were employed to measure the ratio of activation between the medial and lateral quadriceps during the 4, 8, 12, 16, and 20th sets of exercise. Females demonstrated decreased RMS medial-to-lateral quadriceps ratios compared to males (F(1,18) = 5.88, p = 0.026). There was no main effect of set number on RMS quadriceps ratio (p > 0.05). The results of this study suggest that females utilize neuromuscular activation strategies which may contribute to ''dynamic valgus'' and ACL rupture when performing high-risk maneuvers.

Whilst the fauna inhabiting hydrothermal vent structures in the Atlantic Ocean is reasonably well known, less is understood about the spatial distributions of the fauna in relation to abiotic and biotic factors. In this study, a major active hydrothermal edifice (Eiffel Tower, at 1690 m depth) on the Lucky Strike vent field (Mid-Atlantic Ridge (MAR)) was investigated. Video transects were carried out by ROV Victor 6000 and complete image coverage was acquired. Four distinct assemblages, ranging from dense largersized Bathymodiolus mussel beds to smaller-sized mussel clumps and alvinocaridid shrimps, and two types of substrata were defined based on high definition photographs and video imagery. To evaluate spatial variation, faunal distribution was mapped in three dimensions. A high degree of patchiness characterizes this 11 m high sulfide structure. The differences observed in assemblage and substratum distribution were related to habitat characteristics (fluid exits, depth and structure orientation). Gradients in community structure were observed, which coincided with an increasing distance from the fluid exits. A biological zonation model for the Eiffel Tower edifice was created in which faunal composition and distribution can be visually explained by the presence/ absence of fluid exits.

Our aim is to estimate the perspective-effected geometric distortion of a scene from a video feed. In contrast to most related previous work, in this task we are constrained to using low-level, spatio-temporally local motion features only. This particular challenge arises in many semi-automatic surveillance systems which alert a human operator to potential abnormalities in the scene. Low-level, spatio-temporally local motion features are sparse (and thus require comparatively little storage space) and sufficiently powerful in the context of video abnormality detection to reduce the need for human intervention by more than 100-fold. This paper introduces three significant contributions: (i) we describe a dense algorithm for perspective estimation which uses motion features to estimate the perspective distortion at each image locus and then polls all such local estimates to arrive at the globally best estimate, (ii) we also present an alternative coarse algorithm which subdivides the image frame into blocks, and uses motion features to derive block-specific motion characteristics and constrain the relationships between these characteristics, with the perspective estimate emerging as a result of a global optimization scheme, and (iii) we report the results of an evaluation using nine large sets acquired using existing close-circuit television (CCTV) cameras, not installed specifically for the purposes of this work. Our findings demonstrate that both of the proposed methods are successful, their accuracy matching that of human labelling using complete visual data (by the constraints of the setup unavailable to our algorithms).

This book is about the three identities of the videogame, the gamer, and Game Studies. I write that there are no definitive truths but rather discourses and constructions; ideas, actions, beliefs, and practices related to videogames are discourses that merge and shape our perception of videogames as an area of study of its own right. These discursive responses meet and clash creating what we call truths, which are temporary and negotiable.

This perspective is inspired by Foucauldian ideas and present few questions about videogame-related identities in and outside of academe. Does Game Studies have a conceptual core? What makes game studies difficult to be disciplined in academe? What do we learn from the scholarly and popular discourses on videogames that would help understand the identity questions related to games?

I go on to describe what makes the videogame identity according to game studies: aesthetics, fictions, meaning-making, performance, transformation, etc. and what makes it difficult for game studies being an open market of ideas and an academic "un-discipline". This leads me to the gamer's identity: an aficionado first, and a connoisseur of fictional worlds.

Bien que l’interet pour la sphere domestique constitue un enjeu pour la recherche ainsi que pour la conception et l’industrie, les donnees empiriques restent rares. Dans une perspective praxeologique, interactionnelle et naturaliste, cette these contribue a combler ce deficit. Elle identifie des ressources particulieres de l’organisation du quotidien dans deux foyers francais. Par des analyses d’entretiens, et surtout par des analyses de donnees audio-video, la these met en lumiere l’importance du travail interactionnel que les membres realisent chaque jour dans les foyers pour ordonner et rendre intelligibles leurs activites. Ce travail se base sur de multiples pratiques langagieres (verbalisations d’actions, annonces, pre-sequences, sollicitations, injonctions, etc.) qui marquent et donnent le temps et ouvrent des sequences de negociation entre adultes et enfants. A cote des donneurs de temps langagiers, des donneurs de temps corporels, materiels et artefactuels sont egalement mob...

This study aimed to evaluate the effectiveness of online screencast video integration through the Quick Response code (QR code) as mobile learning (m-learning). In the flipped classroom, the QR code is distributed to the students to access the screencast video as a means of disseminating lecture notes through their mobile devices. A total of 19 in-service teachers from Technical Colleges, Teacher Training Institute participated in the study. Through this QR code, students can access the learning materials before they come to class. Next, in the classroom, the lecturer will engage students in collaborative learning activities. Thus, in this paper, the researchers discuss about usability testing using a five-point Likert scale, through a questionnaire consisting of the following four constructs: learnability, efficiency, attitude and flexibility. Results from this study showed that the highest mean is efficiency. Thus, we can conclude that through the integration of video screencast by scanning the QR code, can be a potential tool to support the use of m-learning, and also support the blended learning.
