Pause intensity:a no-reference quality assessment metric for video streaming in TCP networks

In this paper a full analytic model for pause intensity (PI), a no-reference metric for video quality assessment, is presented. The model is built upon the video play out buffer behavior at the client side and also encompasses the characteristics of a TCP network. Video streaming via TCP produces impairments in play continuity, which are not typically reflected in current objective metrics such as PSNR and SSIM. Recently the buffer under run frequency/probability has been used to characterize the buffer behavior and as a measurement for performance optimization. But we show, using subjective testing, that under run frequency cannot reflect the viewers' quality of experience for TCP based streaming. We also demonstrate that PI is a comprehensive metric made up of a combination of phenomena observed in the play out buffer. The analytical model in this work is verified with simulations carried out on ns-2, showing that the two results are closely matched. The effectiveness of the PI metric has also been proved by subjective testing on a range of video clips, where PI values exhibit a good correlation with the viewers' opinion scores. © 2012 IEEE.

Fourth generation evaluation revisited: Testing a revised pause model

This research provides data which investigates the feasibility of using fourth generation evaluation during the process of instruction. A semester length course entitled "Multicultural Communications", (PUR 5406/4934) was designed and used in this study, in response to the need for the communications profession to produce well-trained culturally sensitive practitioners for the work force and the market place. A revised pause model consisting of three one-on-one indepth interviews conducted outside of the class, three reflections periods during the class and a self-reflective essay prepared one week before the end of the course was analyzed. Narrative and graphic summaries of participant responses produced significant results. The revised pause model was found to be an effective evaluation method for use in multicultural education under certain conditions as perceived by the participants in the study. participant self-perceived behavior change and knowledge acquisition was identified through use of the revised pause model. Study results suggest that by using the revised pause model of evaluation, instructors teaching multicultural education in schools of journalism and mass communication is yet another way of enhancing their ability to become both the researcher and the research subject. In addition, the introduction of a qualitative model has been found to be a more useful way of generating participant involvement and introspection. Finally, the instructional design of the course used in the study provides communication educators with a practical way of preparing their students be effective communicators in a multicultural world.

Kinetic modeling of molecular motors: pause model and parameter determination from single-molecule experiments

Single-molecule manipulation experiments of molecular motors provide essential information about the rate and conformational changes of the steps of the reaction located along the manipulation coordinate. This information is not always sufficient to define a particular kinetic cycle. Recent single-molecule experiments with optical tweezers showed that the DNA unwinding activity of a Phi29 DNA polymerase mutant presents a complex pause behavior, which includes short and long pauses. Here we show that different kinetic models, considering different connections between the active and the pause states, can explain the experimental pause behavior. Both the two independent pause model and the two connected pause model are able to describe the pause behavior of a mutated Phi29 DNA polymerase observed in an optical tweezers single-molecule experiment. For the two independent pause model all parameters are fixed by the observed data, while for the more general two connected pause model there is a range of values of the parameters compatible with the observed data (which can be expressed in terms of two of the rates and their force dependencies). This general model includes models with indirect entry and exit to the long-pause state, and also models with cycling in both directions. Additionally, assuming that detailed balance is verified, which forbids cycling, this reduces the ranges of the values of the parameters (which can then be expressed in terms of one rate and its force dependency). The resulting model interpolates between the independent pause model and the indirect entry and exit to the long-pause state model

Das Spiel von Grundschulkindern in der großen Pause

Wer schon einmal für kurze Zeit spielenden Kindern zugeschaut hat, mag es als faszinierend empfunden haben, dass das gemeinsame Spiel manchmal „wie von selbst“ abzulaufen scheint. Durch eine intensive Auseinandersetzung mit dessen Theorie und gezielten Beobachtungen ist allerdings festzustellen, dass Spiel eigentlich gar kein „Kinderspiel“, sondern vielmehr eine komplexe Tätigkeit ist. Jedes Spiel weist eine in sich abgeschlossene eigene Wirklichkeit auf, welche sich von der äußeren allgemeingültigen Wirklichkeit abhebt (vgl. Bateson 2007, S. 198f; Oerter 1997, S. 117). Ein Spielrahmen ist vorhanden, der die Situation als Spiel definiert und dessen Grenzen festlegt (vgl. Goffman 1973, S. 74). Im gemeinsamen Spiel ist es deshalb notwendig, dass sich die Teilnehmer das situative Vorhandensein des spezifischen Rahmens und dessen Inhalt mit bestimmten Signalen anzeigen und ihre Auffassungen aufeinander abstimmen (vgl. Oerter 1997, S. 117). Die dafür verwendeten Mitteilungen sind metakommunikativ, d. h. sie geben Auskunft darüber, wie die Kommunikation selbst im Folgenden zu verstehen ist, nämlich immer vor dem Hintergrund, dass „nur gespielt wird“. Erst dadurch können die Mitspieler das Verhalten der anderen als gespielt oder echt einordnen, sodass Missverständnisse vermieden werden (vgl. Bateson 2007, S. 193ff, 206; Oerter 1997, S. 117). Es ist erstaunlich, wie dies Kindern teilweise nur mit wenigen Worten, Gesten oder Handlungen gelingt. Der obige Ausschnitt aus einem Beobachtungsprotokoll zum Spiel von zwei Grundschülern in der großen Pause zeigt, dass nicht nur für Außenstehende, sondern mitunter auch für die Kinder selbst, nicht immer eindeutig oder bewusst ist, wie dieser Vorgang vonstattengeht. Justus und Raphael stimmen zwar darin überein, dass sie gemeinsam ein Spiel gespielt haben, können dieses aber weder benennen, noch beschreiben. Trotzdem scheinen sie beide die gleiche Vorstellung vom Spielablauf und dessen Inhalt gehabt bzw. das Spiel gleichermaßen gerahmt zu haben und zu einer Übereinkunft diesbezüglich gekommen zu sein. Ebenso wie die große Pause zur Schule gehört, gehört zur großen Pause wiederum - zumindest in der Grundschule - das Spiel. Damit ist das Pausenspiel i. d. R. ein fester Bestandteil des Schulalltags eines Grundschülers. Wie bereits angedeutet, leisten die Kinder sogar dabei etwas, nämlich die gemeinsame Bildung und Erhaltung eines gemeinsamen Spielrahmens durch Interaktion. In dieser Arbeit wird deshalb der folgenden Frage nachgegangen: Wie stellen Grundschulkinder in der großen Pause einen gemeinsamen Spielrahmen her und wie erhalten sie diesen aufrecht? Die Beschäftigung mit dieser Frage ist insbesondere für (zukünftige) Lehrpersonen lohnenswert, denn sie kann den Blick auf das Pausenspiel ggf. insofern verändern, dass es mehr wertgeschätzt wird. Ziel dieser Arbeit ist es, Aussagen zu der den Spielrahmen betreffenden Praxis von Grundschulkindern in der großen Pause herauszubilden. Dazu werden zunächst das Spiel und dessen Rahmen theoretisch abgehandelt. Vor diesem Hintergrund soll die Frage weiterführend mit Hilfe von Szenen zur praktischen Umsetzung gemeinsamer Spiele, die im Rahmen einer empirischen Untersuchung im Feld tatsächlich beobachtet und dokumentiert wurden, beantwortet werden. Es wird also nicht das Ziel verfolgt, eine eigenständige Theorie aus den Daten abzuleiten, vielmehr soll die bestehende Theorie mit realen, authentischen Beispielen aus dem Pausenalltag von Grundschülern unterlegt und ergänzt werden.

Associations prospectives entre l'environnement des repas en famille et le développement bio-psycho-social d'enfants d'âge scolaire

Contexte. Depuis quelques années, plusieurs études se sont intéressées aux effets protecteurs des repas en famille sur divers aspects du développement des enfants et des adolescents. Objectif. Identifier les associations prospectives entre l'environnement des repas en famille à 6 ans et le développement bio-psycho-social à 10 ans. Méthode. Les participants sont 1 085 filles et 1 138 garçons faisant partie de l'Étude Longitudinale du Développement des Enfants du Québec (ÉLDEQ), qui a sélectionné un échantillon aléatoire et stratifié en utilisant le registre des naissances du Québec. Dans ce devis prospectif-longitudinal, les parents ont fourni une mesure sur l'environnement de leurs repas en famille à l'âge de 6 ans. Quatre années plus tard, les parents ont également fourni des mesures sur le niveau de condition physique de leur enfant ainsi que sa fréquence de consommation de boissons gazeuses; les enseignants ont mesuré la réussite en lecture et en mathématiques; les enfants ont auto-rapporté leurs niveaux d’agressivité physique globale, d’opposition, du trouble du comportement non agressif et d’agressivité réactive. Des analyses de régressions multiples ont été réalisées. Résultats. Un environnement plus sain lors des repas en famille à 6 ans a prédit les bénéfices suivants à 10 ans : une augmentation de la condition physique (β = 0,24; 95 % intervalle de confiance [IC], 0,12 à 0,36) ainsi qu'une diminution de la consommation de boissons gazeuses (β = -0,43; 95 % IC, -0,62 à -0,23), de l'agressivité physique globale (β = -0,38; 95 % IC, -0,58 à -0,18), de l'opposition (β = -0,72; 95 % IC, -1 à -0,4), du trouble du comportement non agressif (β = -0,33; 95 % IC, -0,50 à -0,17) et de l'agressivité réactive (β = -0,70; 95 % IC, -0,98 à -0,42). Contrairement à nos attentes, l'environnement des repas en famille n'était pas significativement relié au rendement scolaire. Conclusion. Les repas familiaux ont une forte influence à long terme sur le développement de l'enfant, par rapport à sa santé physique et à son ajustement social. Par conséquent, ils pourraient nourrir une campagne informative intéressante qui porterait sur la promotion de la santé mentale et physique des jeunes à travers ce rituel social.

Compact Ag@fe3o4 Core-shell Nanoparticles By Means Of Single-step Thermal Decomposition Reaction.

A temperature pause introduced in a simple single-step thermal decomposition of iron, with the presence of silver seeds formed in the same reaction mixture, gives rise to novel compact heterostructures: brick-like Ag@Fe3O4 core-shell nanoparticles. This novel method is relatively easy to implement, and could contribute to overcome the challenge of obtaining a multifunctional heteroparticle in which a noble metal is surrounded by magnetite. Structural analyses of the samples show 4 nm silver nanoparticles wrapped within compact cubic external structures of Fe oxide, with curious rectangular shape. The magnetic properties indicate a near superparamagnetic like behavior with a weak hysteresis at room temperature. The value of the anisotropy involved makes these particles candidates to potential applications in nanomedicine.

A COMPETÊNCIA LEXICAL DE ALUNOS UNIVERSITÁRIOS APRENDENDO A LER EM INGLÊS COMO LÍNGUA ESTRANGEIRA

This article presents a characterization of the lexical competence (vocabulary knowledge and use) of students learning to read in EFL in a public university in São Paulo state. Although vocabulary has been consistently cited as one of the EFL reader´s main source of difficulty, there is no data in the literature which shows the extent of the difficulties. The data for this study is part of a previous research, which investigates, from the perspective of an interactive model of reading, the relationship between lexical competence and EFL reading comprehension. Quantitative as well as qualitative data was considered. For this study, the quantitative data is the product of vocabulary tests of 49 subjects while the qualitative data comprises pause protocols of three subjects, with levels of reading ability ranging from good to poor, selected upon their performance in the quantitative study. A rich concept of vocabulary knowledge was adapted and used for the development of vocabulary tests and analysis of protocols. The results on both studies show, with a few exceptions, the lexical competence of the group to be vague and imprecise in two dimensions: quantitative (number of known words or vocabulary size) and qualitative (depth or width of this knowledge). Implications for the teaching of reading in a foreign context are discussed.

Coordination dynamics and attentional costs of continuous and discontinuous bimanual circle drawing movements

It has been suggested that the temporal control of rhythmic unimianual movements is different between tasks requiring continuous (e.g., circle drawing) and discontinuous movements (e.g., finger tapping). Specifically, for continuous movements temporal regularities are ail emergent property, whereas for tasks that involve discontinuities timing is ail explicit part of the action goal. The present experiment further investigated the control of continuous and discontinuous movements by comparing the coordination dynamics and attentional demands of bimanual continuous circle drawing with bimanual intermittent circle drawing. The intermittent task required participants to insert a 400 ms pause between each cycle while circling. Using dual-task methodology, 15 right-handed participants performed the two circle drawing tasks, while vocally responding to randomly presented auditory probes. The circle drawing tasks were performed in symmetrical and asymmetrical coordination modes and at movement frequencies of 1 Hz and 1.7 Hz. Intermittent circle drawing exhibited superior spatial and temporal accuracy and stability than continuous circle drawing supporting the hypothesis that the two tasks have different underlying control processes. In terms of attentional cost, probe RT was significantly slower during the intermittent circle drawing task than the continuous circle drawing task across both coordination modes and movement frequencies. Of interest was the finding that in the intermittent circling task reaction time (RT) to probes presented during the pause between cycles did not differ from the RT to probes occurring during the circling movement. The differences in attentional demands between the intermittent and continuous circle drawing tasks may reflect the operation of explicit event timing and implicit emergent timing processes, respectively.

Relationship between attack and skipping in taekwondo contests

Santos, VGF, Franchini, E, and Lima-Silva, AE. Relationship between attack and skipping in Taekwondo contests. J Strength Cond Res 25(6): 1743-1751, 2011-The purpose of this study was to determine the relationship between attack time (AT) and skipping time (ST) during the 2007 Taekwondo World Championship and 2008 Beijing Olympic Games. A total of 22 matches (65 rounds, 13 semifinals, and 8 finals) from the World Championship and 23 matches (63 rounds, 22 rounds with 16 athletes each and 1 quarterfinal round) from the Olympic Games, both in the male category, were assessed using time-motion analysis. The AT was considered as the total time during which the athlete attacked or tried to attack, whereas ST was the total time without attempting to attack. The ratio of AT to ST was similar to 1:7 based on the data pooled from the 2 competitions. The AT/ST ratio was significantly lower for the World Championship than for the Olympic Games (p <= 0.05). In the Olympic Games, no consistent differences across weight divisions were found. However, during the World Championship, the heavier weight divisions (>78 kg) exhibited a lower average AT, lower summed AT, lower attack numbers (ANs) and higher average ST than lighter weight divisions (<58 kg, p <= 0.05). For both competitions, the ST was lower, and the ANs and AT/ST ratio were higher in round 3 than in round 1 or 2. In conclusion, the results of this study suggest that matches in the Olympic Games were less cadenced than in the World Championship, but that in both competitions, the intensity of the match increased in round 3. Practically, these data suggest that coaches need to structure Taekwondo training sessions in a manner that allows the work/pause ratio to mirror the physical demand imposed during competitions.

A review of time-motion analysis and combat development in mixed martial arts matches at regional level tournaments

Mixed martial arts (MMA) have become a fast-growing worldwide expansion of martial arts competition, requiring high level of skill, physical conditioning, and strategy, and involving a synthesis of combat while standing or on the ground. This study quantified the effort-pause ratio (EP), and classified effort segments of stand-up or groundwork development to identify the number of actions performed per round in MMA matches. 52 MMA athletes participated in the study (M age = 24 yr., SD = 5; average experience in MMA = 5 yr., SD = 3). A one-way analysis of variance with repeated measurements was conducted to compare the type of action across the rounds. A chi-squared test was applied across the percentages to compare proportions of different events. Only one significant difference (p < .05) was observed among rounds: time in groundwork of low intensity was longer in the second compared to the third round. When the interval between rounds was not considered, the EP ratio (between high-intensity effort to low-intensity effort plus pauses) WE S 1:2 to 1:4. This ratio is between ratios typical for judo, wrestling, karate, and taekwondo and reflects the combination of ground and standup techniques. Most of the matches ended in the third round, involving high-intensity actions, predominantly executed during groundwork combat.
