This document provides an overview and analysis of using vlogs on YouTube as a platform for language learning and intercultural exchange. It discusses the theoretical framework of social media-based language learning and interactive multimodal platforms. The research focuses on analyzing a corpus of 38 videos from an American learner's French-language vlog channel on YouTube. The analysis finds that the vlogs provide opportunities to enhance spoken production skills, digital literacy skills, and multilingual peer learning. However, they also present some limits regarding ethical issues, privacy concerns, and commercial aspects. Overall, the vlogs have potential for informal language learning and understanding cultural perspectives but may require guidance in a formal teaching context.
The document discusses two studies that examined the use of Twitter to build community. The first study looked at students in an Intermediate French class who tweeted in French 3 times per week. Students reported that Twitter helped build community with classmates and connect with French students abroad. Analysis of tweets found high levels of affective and interactive indicators. The second study examined graduate teaching assistants in a Foreign Language Teaching Methods course who tweeted about their experiences. Surveys found that participants connected most with other instructors and tweeted about reactions to teaching and seeking advice. Both studies aimed to determine if Twitter facilitated a sense of community and how participants interacted.

UP Election 2017: It's no longer about caste & religionInves Trekk
The political consciousness of the people of Uttar Pradesh, has evolved materially in past one decade. Contrary to the popular narrative, the caste and religion, though still relevant, are not the primary considerations in the voters' mind. Nowhere, the voters are inclined to elect a candidate purely on the basis of caste or religion.
Though these are still early days and the situation could change dramatically in next few days, I would still hazard an assessment of the election outcome.
In my view BJP will emerge as the single largest party, if Congress allies with SP or BSP.
Otherwise, BJP is poised to get a strong majority on its own.
This document summarizes a research paper about using vlogs on YouTube as a platform for informal language learning and intercultural exchange. The researchers analyzed comments on three vlogs posted by an American learning French on YouTube. They found that vlogs provided opportunities for practicing speaking skills, peer learning, and discussions of cultural topics/stereotypes. However, vlogs were also limited by users' linguistic abilities and potential ethical issues when using social media for education. While vlogs showed potential, more research is needed on interactions in unstable online contexts and pedagogical uses of language vlogs.

This document discusses various models of telecollaboration that can be used in university education to internationalize classrooms and develop intercultural competence online. It describes several approaches including e-tandem exchanges between pairs of language learners, the Cultura model which involves students from different countries answering questionnaires and discussing responses, and the Soliya model where students engage in facilitated online dialogues on global issues. It also discusses combining virtual exchanges with physical study abroad through projects like Virtual International Partners which connect students planning to study abroad. Telecollaboration provides opportunities for internationalizing curricula and benefiting students who are not physically mobile through collaborative online intercultural learning experiences.
The top three reasons mentioned by practitioners for why telecollaborative exchange was not more popular in university education were:
1. Lack of time (Mentioned by 49/98 practitioners)
2. Technical issues/lack of support (Mentioned by 28/98 practitioners)
3. Concerns about assessment/recognition of telecollaboration in the curriculum (Mentioned by 20/98 practitioners)

Telecollaborative exchange involves groups of students engaging in online intercultural interaction and collaboration with partner classes from other cultures or locations, guided by educators. Effective tasks go beyond superficial exchanges, instead providing opportunities for genuine collaboration, such as jointly creating presentations. Tasks should also introduce intercultural interaction gradually and provide opportunities for reflection on the online interaction.

SDSS1335+0728: The awakening of a ∼ 106M⊙ black hole⋆Sérgio Sacani
Context. The early-type galaxy SDSS J133519.91+072807.4 (hereafter SDSS1335+0728), which had exhibited no prior optical variations during the preceding two decades, began showing significant nuclear variability in the Zwicky Transient Facility (ZTF) alert stream from December 2019 (as ZTF19acnskyy). This variability behaviour, coupled with the host-galaxy properties, suggests that SDSS1335+0728 hosts a ∼ 106M⊙ black hole (BH) that is currently in the process of ‘turning on’. Aims. We present a multi-wavelength photometric analysis and spectroscopic follow-up performed with the aim of better understanding the origin of the nuclear variations detected in SDSS1335+0728. Methods. We used archival photometry (from WISE, 2MASS, SDSS, GALEX, eROSITA) and spectroscopic data (from SDSS and LAMOST) to study the state of SDSS1335+0728 prior to December 2019, and new observations from Swift, SOAR/Goodman, VLT/X-shooter, and Keck/LRIS taken after its turn-on to characterise its current state. We analysed the variability of SDSS1335+0728 in the X-ray/UV/optical/mid-infrared range, modelled its spectral energy distribution prior to and after December 2019, and studied the evolution of its UV/optical spectra. Results. From our multi-wavelength photometric analysis, we find that: (a) since 2021, the UV flux (from Swift/UVOT observations) is four times brighter than the flux reported by GALEX in 2004; (b) since June 2022, the mid-infrared flux has risen more than two times, and the W1−W2 WISE colour has become redder; and (c) since February 2024, the source has begun showing X-ray emission. From our spectroscopic follow-up, we see that (i) the narrow emission line ratios are now consistent with a more energetic ionising continuum; (ii) broad emission lines are not detected; and (iii) the [OIII] line increased its flux ∼ 3.6 years after the first ZTF alert, which implies a relatively compact narrow-line-emitting region. Conclusions. We conclude that the variations observed in SDSS1335+0728 could be either explained by a ∼ 106M⊙ AGN that is just turning on or by an exotic tidal disruption event (TDE). If the former is true, SDSS1335+0728 is one of the strongest cases of an AGNobserved in the process of activating. If the latter were found to be the case, it would correspond to the longest and faintest TDE ever observed (or another class of still unknown nuclear transient). Future observations of SDSS1335+0728 are crucial to further understand its behaviour. Key words. galaxies: active– accretion, accretion discs– galaxies: individual: SDSS J133519.91+072807.4
Candidate young stellar objects in the S-cluster: Kinematic analysis of a sub...Sérgio Sacani
Context. The observation of several L-band emission sources in the S cluster has led to a rich discussion of their nature. However, a definitive answer to the classification of the dusty objects requires an explanation for the detection of compact Doppler-shifted Brγ emission. The ionized hydrogen in combination with the observation of mid-infrared L-band continuum emission suggests that most of these sources are embedded in a dusty envelope. These embedded sources are part of the S-cluster, and their relationship to the S-stars is still under debate. To date, the question of the origin of these two populations has been vague, although all explanations favor migration processes for the individual cluster members. Aims. This work revisits the S-cluster and its dusty members orbiting the supermassive black hole SgrA* on bound Keplerian orbits from a kinematic perspective. The aim is to explore the Keplerian parameters for patterns that might imply a nonrandom distribution of the sample. Additionally, various analytical aspects are considered to address the nature of the dusty sources. Methods. Based on the photometric analysis, we estimated the individual H−K and K−L colors for the source sample and compared the results to known cluster members. The classification revealed a noticeable contrast between the S-stars and the dusty sources. To fit the flux-density distribution, we utilized the radiative transfer code HYPERION and implemented a young stellar object Class I model. We obtained the position angle from the Keplerian fit results; additionally, we analyzed the distribution of the inclinations and the longitudes of the ascending node. Results. The colors of the dusty sources suggest a stellar nature consistent with the spectral energy distribution in the near and midinfrared domains. Furthermore, the evaporation timescales of dusty and gaseous clumps in the vicinity of SgrA* are much shorter ( 2yr) than the epochs covered by the observations (≈15yr). In addition to the strong evidence for the stellar classification of the D-sources, we also find a clear disk-like pattern following the arrangements of S-stars proposed in the literature. Furthermore, we find a global intrinsic inclination for all dusty sources of 60 ± 20◦, implying a common formation process. Conclusions. The pattern of the dusty sources manifested in the distribution of the position angles, inclinations, and longitudes of the ascending node strongly suggests two different scenarios: the main-sequence stars and the dusty stellar S-cluster sources share a common formation history or migrated with a similar formation channel in the vicinity of SgrA*. Alternatively, the gravitational influence of SgrA* in combination with a massive perturber, such as a putative intermediate mass black hole in the IRS 13 cluster, forces the dusty objects and S-stars to follow a particular orbital arrangement.

Authoring a personal GPT for your research and practice: How we created the Q...Leonel Morgado
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.

Wereport the study of a huge optical intraday flare on 2021 November 12 at 2 a.m. UT in the blazar OJ287. In the binary black hole model, it is associated with an impact of the secondary black hole on the accretion disk of the primary. Our multifrequency observing campaign was set up to search for such a signature of the impact based on a prediction made 8 yr earlier. The first I-band results of the flare have already been reported by Kishore et al. (2024). Here we combine these data with our monitoring in the R-band. There is a big change in the R–I spectral index by 1.0 ±0.1 between the normal background and the flare, suggesting a new component of radiation. The polarization variation during the rise of the flare suggests the same. The limits on the source size place it most reasonably in the jet of the secondary BH. We then ask why we have not seen this phenomenon before. We show that OJ287 was never before observed with sufficient sensitivity on the night when the flare should have happened according to the binary model. We also study the probability that this flare is just an oversized example of intraday variability using the Krakow data set of intense monitoring between 2015 and 2023. We find that the occurrence of a flare of this size and rapidity is unlikely. In machine-readable Tables 1 and 2, we give the full orbit-linked historical light curve of OJ287 as well as the dense monitoring sample of Krakow.

TOPIC OF DISCUSSION: CENTRIFUGATION SLIDESHARE.pptxshubhijain836
Centrifugation is a powerful technique used in laboratories to separate components of a heterogeneous mixture based on their density. This process utilizes centrifugal force to rapidly spin samples, causing denser particles to migrate outward more quickly than lighter ones. As a result, distinct layers form within the sample tube, allowing for easy isolation and purification of target substances.

5. Learners’ 2.0 role and new skills
Learners’ 2.0 skills:
• Interacting and telecolaborating in one or more foreign
languages
• Lifelong learning skills
• Social networking
• Learning in formal and informal contexts
• Being able to evaluate, select, use, publish and share relevant
online resources
• Developing a creative state of mind (Guth and Helm : 2003)
• Developing multimodal skills : expressing ideas through
different modes such as words, pictures or 3D models
(Hauck, 2010)

6. Interactive Multimodal
Platforms (IMP)
Interactive
multimodal platforms
(IMP) are growing
rapidly and becoming
increasingly popular.
• One of the first IMPs was
YouTube, which allowed users
to comment on a shared
video asynchronously, via
either text or video (Herring,
2015: 2).
6
In the Internet’s multilingual
context, it offers a great potential
for learning foreign languages:
• YouTube is based on the visual and include a
great deal of interaction with strangers.
(Barton and Lee, 2013 : 40).
• The multimodal affordances of the site are
especially valuable for language learners of all
sorts to practice speaking, writing and
listening (Barton and Lee, 2013 : 156).
Autonomous and informal learning
is also facilitated:
• Peer learning and stress-free environment
(Barton and Lee, 2013).
7. Intercultural communication in a
digital era
The emergence of new medias and technologies of
communication are intensifying globalization (Blommaert, 2011)
and are complicating the notion of “superdiversity” (Vertovec,
2007).

Multimodal corpora are abundant (Develotte,
2012)
Multimodal data should be studied online, in
order to preserve the ecology of the
discursive production. (Paveau, 2015)
As a result, the researcher is faced with working
with constantly evolving data. (Combe, in

For unreal, you can say « dément.e » :) it’s an adjective which means « cool » for instance you can say :) Cette fête était démente,
Ce plat est dément, ce T-shirt est dément…Etc. (this party was cool, this meal is cool, this T-shirt is cool)
baz baz: In French there is an argot that we use very often, « kiffer » which is synonym of liking or loving something.
Exemple: Je kiff aller en France (I like going to France) or j’ai kiffé ta vidéo (I liked your video).This word, in fact a verb,
it’s used with friends
FleurDeCersier: I often heard that word in France (I am German). In German « kiffen » (verbs end in en) means
« smoking marijuana »
JSY: Lol!! Thanks for the info ^^ it’s good to know. I will never see this expression in the same way from now on^^…
Besides, as Baz Baz says, it’s a very common word in France (I say it a lot, lol) :D ahahaha

29. Local tensions
— Careful!!!PARIS is not FRANCE!!!!!! Parisians heads of dogs, parigots (old
fashioned term for a person living in Paris) heads of veal !!!!!!! Lolololololol
don’t judge French and France in Paris, but outside PARIS !!!!!!! [...]
◦ A: Paris is a part of France whether you like it or not
◦ B: But Paris is not France whether you like it or not
◦ A: I don’t understand your answer. Parisians are French, right?
◦ B: But Paris is not the entire France
◦ A: So what, nobody says so. If he wants to talk about the differences between France and the
USA due to his experiences in Paris I don’t see the problem.. Parisians are French like
everybody.
◦ …
◦ E: + marco miaou vive paris ! and if you like it, you’re not French !
◦ F: +nicolas renou Bullshit if you don’t like Paris you are french anyway and who cares it’s the
capital, what is this conformism
— WHY visit PARIS !!!! it’s shit …. People are bad there…..
◦ G: Yeah, go to the countryside people are welcoming and you’ll eat MORE and BETTER
◦ H: People may not be nice but it’s not a reason to say it’s shit!!

30. Local tensions
— There is a big difference between France and
Paris! Hehe
◦ A: it’s true, I live in the countryside and it’s less
polluted than Paris.
◦ B: Rarely heard bullshit like this! Another
frustrated redneck, before we had the famous
“parigot head of veal” on the road and now this.
what a national unity...
◦ A: Oh the polluted parigot calm down
◦ B: I’m not from Paris idiot

31. From ethnocentric stages …
Denial
• It’s NOTTRUE there are a thousands of channels in France you only had theTNT one. I
imagine that you went to France a while ago plenty of TV programs have been created
since then!
• You are neither American nor French you’re a bloody Asiatic, France invented your country
…….. 0 history, just European sperm
• Hey guys, there are more gays in Paris (...) than in his littleTexas village, you have to
understand him!
Defense
• Nay in Brittany it’s better we have nice Brittany crepes.
Minimization
• When you say there a millions of channels…This may be a little swearing in a church?
Now there are maybe 30 free channels onTNT, an average of 2 local channels per greater
communities and lots of paying channels. But surely no more than 500.
31
32. …To ethnorelative stages
32
Acceptance
• We payTV tax for nothing in France because it is shit as usual
• It’s true that lots of young people smoke in France and lot of my friends too,
which is not good for them or me.
Adaptation
• What I say here is not mean and I respect your ideas. I have mine also regarding
Americans but I like them anyway :) ciao amigo
• I like what you say mister American
Integration
• I go every 3 months to the US, I have family there (Chicago) (...) Americans are
more open minded compared to French (...) I love my country, France (...) but if I
had the choice, I would prefer to be American.

Results
• Peer collaboration and informal language learning, crystallise tensions in a globalized and digital era
Potential
• Spoken production speaking skills, digital literacy skills, multilingual peer learning, understanding opinion
conflicts through cultural stereotypes, building intercultural skills
Limits
• Ethical and linguistic mainly due toYouTube platform andYouTubers’ skills.
In a formal teaching context, Michael’s vlog can be a resource for teachers by
helping them think about:
• The potential of a multimodal interactive platform for language learning and for developing digital literacy
skills
• The implications of publishing and interacting on an IMP likeYouTube.
