The Blue Beetle. Weeping down upon the underworld to smash ganglin' comes the mysterious, all-powerful character who is a problem to the police but a crusader for law. In reality, Dan Garrett, a rookie patrolman, loved by everyone but suspected by none of being the Blue Beetle. As the Blue Beetle, he hides behind a sprained mask and a suit of impenetrable blue chain armor, flexible as silk, but stronger than steel. Today's episode of the Blue Beetle is entitled The Frame-Up. Stanley Rogers, convicted of killing Beth Doyleton, small-time loan shark and gambler, is in the death house at the state penitentiary awaiting death by electrocution. Rogers, Zion of a prominent and respectable family, claims he shot in self-defense. But the jury thought otherwise. As our story opens, patrolman Dan Garrett, who in secret is really the Blue Beetle, is entering the little apothecary shop of Dr. Franz, his confidant and friend. Hello, Doc. Where are you? I am back here. Is that you, Danny? Yes. What are you doing? I'm working on some experiments in my laboratory. How are you this morning? Oh, I'm feeling great. I've been waiting for you to show up. Anything special? Here's something in the personal column of this morning's paper that might introduce you to the Blue Beetle. I am desperate. My brother awaits death by electrocution for a crime he did not commit. Can you help me? Brenda Rogers. But that must be Stanley Rogers who shot Beth Doyleton, a small-time regattier. Yes. Rather strange case, if I remember correctly. Rogers admitted he shot Doyleton, but claimed it was in self-defense. He shot him with a pistol he found in Doyleton's apartment, I believe. Yeah. Wasn't it brought out in the file that Rogers hold Doyleton a large sum of money? Yes. He borrowed from him on several occasions to cover his gambling water. Where did Rogers meet Doyleton? He was introduced to Rogers by a girl, chance acquaintance of a gambling criminal. That's too bad. Rogers comes with a good family. I kind of understand his getting mixed up in such a thing. Well, he was a little wild at college. Too much money to spend. Often at an early age, wasn't he? Yeah. He was really raised by an older sister who spoiled him. He's certainly in a spot now. Yes, he is. What are you going to do about that notice in the newspaper? Well, I'm going to pay a visit to young Rogers in the death house. Never talk with him. As Dan Garrett? Or as the Blue Beetle? As the Blue Beetle. But how are you going? I'd like to use some of your invisible paint, Doc, but I can get to Rogers without anyone knowing it. It'll be dangerous if you're caught. I haven't been able to perfect the liquid yet. A little serve my purpose. I won't be with Rogers very long. Well, be careful, Danny boy. Well, don't worry, Doc. Well, I've got to get down to headquarters now. If I can, I'll be back later to change into my Blue Beetle chain armor and mask. I'll be here to help you with any time you want me, Danny. Thanks, Doc. The learn. I'm going to read up a little on the Rogers case. Panigan, get your feet off that table and stand at attention. When your superior officer enters the room. Yes. Oh, hello, Danny. It's you. I was just getting a little shut-eye. The night's the time for sleeping? Yeah. I know, but I've been on extra duty lately. And you have to catch up when you're asleep with headquarters. Yeah, that's it. And besides, I was waiting for you. I want to ask you a few questions, Mike.  If it's about crime and criminals, officer Mike Panigan is a regular encyclopedia. Encyclopedia? Yeah, that's it. What do you know about that Doyleton? Oh, him. He was a small-time loan shark before the Rogers vibe bumped him up. Do you think Roger's killing of Doyleton was premeditated? No, I don't. Maybe do I? This Georgetown guy was a bad egg. Where could I find out more about him? Well, maybe Charlie Storm, but the sun could help you out. Oh, that's a good idea. I'll give him a ring. They say, Dan, why are you so interested in this Rogers case? Oh, I'm interested in the loan shark rackets, and I want to find out all I can about those connected with it. Hello, son? Give me Charlie Storm, please. And maybe the commissioner would assign us both to it if we asked him. Later, perhaps, Mike. The president, I... Oh, hello, Charlie. This is Dan, Dan Garrett. See, what do you know about that Doyleton? Yeah? Yeah, Maroney? Top man, huh? Really? That high? Hey, that's very interesting, Charlie. I think I'll get busy and really dig into this loan shark business. Well, Danny, what did you find out at police headquarters? I phoned Charlie Storm with the sun. He should be able to give you value of his information. He told me that a man named Maroney was the top man in the loan shark racket. Was Doyleton associated with him? No. The point was to hang around the gambling holes and racetracks by means of attractive girls in his employ who strike up casual acquaintances with heavy bettors.  I see. Would you say he wasn't working with Maroney? No. In fact, he was planning to set up a rival loan business working among the poorer class of unfortunate people who really need money. But that's a legitimate business. Not the way these loan sharks run it. Well, how do you mean? Well, I'd say a man borrowed a hundred dollars. He also had to take out life insurance for the same people to assure the loan being paid back in case he died. These costs and interests on the loan are pyramided so that in some cases the borrower has paid over five and six times the amount of the original loan and he still owes the principal. Boy, that's crooked business. Of course it is. And that's the racket the blue beetle is going to smash. Where is the blue beetle going to light first? In the fell of Stanley Rogers at the State Penitentiary. Have you the liquid of invisibility, Danny? Yeah, right here, Doc. I'm going to use it.  The blue beetle is going to fly right into jail. Meanwhile, in the electrocution chamber at the State Penitentiary, some officials are testing the lethal equipment. How about the electrodes, Sam? Cleaners and I've played warden. And the straps. All in order, sir. Have you tried the switches? I was just about to do that, sir. All right. Shoot some juice through and check your dial. Yes, sir. Just a moment. I'll give you the 1,800 volts and then jump it to 2,000. All right. What's your dial indicate, Sam? 2,000. That should be strong enough for young Rogers. Yeah, it's too strong, in fact. But the court has ordered its execution and it's our duty to carry out their orders. Want any more? Nope.  That's all for today. I'm going to my office. I'd like to see you there later to check the tales for the execution in the morning. Yes, sir. Has Father Callaghan seen young Rogers today? I think he's with him now, sir. Ask him to see me in my office when he's finished with Rogers. My son. Are there any messages you'd like me to give to anyone? What's the use, father? Everyone thinks I'm a murderer. What about your sister, Brenda? She still believes in you. What can I say to her that she doesn't already know? Perhaps a little word of farewell? Farewell. Farewell. Yes, I'm going to farewell. I'm going to burn for something I didn't do. There, there, my son.  Try to face things bravely. Secure in the knowledge that there is another life after death. But I'm not ready for death yet, father. I want my life now. Why can't somebody do something for me? I'm innocent. I'm innocent, I tell you. Everything possible to do has been done, my son. No work from the governor, father. I'm sorry, my son. Perhaps later tonight. Your lawyer has been in touch with his secretary. We are all doing everything we can. Thank you, father. I'm sorry I acted as I did. Please leave me now. I'd like to be alone. Farewell. Good night, my son. Good night, father. Oh, God, wait for come with me, please. I'd like to speak with you a minute. Sure thing, father. I'll write with you. What was that humming there? Was that the sound of that? That was the sound of the blue beetle's magic rays. The blue beetle? Yes, the blue beetle. But I can't see anyone. I am invisible. What are you doing here? I've come to help you. Who sent you? Your sister. My sister? But how did she... Never mind how she got in touch with me. Now listen to what I have to say. Speak softly so the guard won't hear you. This invisibility of mine may not last long. All right. Now, tell me what happened the night you shot Doyleston. I didn't shoot him. But you admitted in court that... Yes, I know I did. And at that time, I thought I had shot him. I... I don't understand. The night of the shooting, I'd gone to Doyleston's apartment to ask him for more time in which to pay my application. Oh, hello, Rogers. Come to pay your notes. Well, I'd like to talk it over with you. Come in. Oh, uh, you know Maroney here? Yes, I met him at the Golden Fencing Club. Hello, Rogers. Hello, Mr. Maroney. Well, I'll leave you two together. There's that private business to talk about. Oh, look, Maroney. Why don't you step into the bedroom there and wait till I finish with Rogers? It won't take long. And you and I can finish our business. Okay, but make it snappy. I ain't going on. Now, what have you got to say, Rogers? Well, I... I can't tell you what I owe you now. If you'll wait till I get the principle of my father's estate next year, I'll pay you double. I can't wait that long. When I lend money, I've got to get it back to lend to somebody else. That's how I make a living. But I thought... Don't be silly. Now, listen, every dollar I lend brings me back five or even $10 interest. The guys that borrow from me pay me back, or else. But I can't pay you back now. Well, then, tomorrow morning, your boss is going to know about this. You can't do that. I lose my job at the bank.  Hey, there's an idea. Your sister's got what it takes. She's a swell-looking gal. I could use her in my business. What do you mean? I could use her at the gambling joint. She could leave the customers on and persuade them to gamble heavily. They lose money, need to borrow. Then she introduces them to me. That's what happened to me. Oh, sure. And that's the way the old-army game works. Why, you dirty, slimy rat. My sister wouldn't wait for feet on you. Well, maybe after I told her to jam your inch, she might consider my proposition. That is, if she loved you, maybe she'd be worth more to me. You wouldn't stare a peltier with any stuff. I go and beat it, kid. I got other business tonight. I won't leave this room until you promise that. I'll beat it.   This will stop you. Down that gun, Rogers. You can't get away. And that's just the way it happens. Then... then you did shoot Doyleton, Rogers. I thought I did at the time, blue people. In the excitement, I imagined I pulled the trigger. But since then, as I think back, I know I didn't pull the trigger of that gun. Did you take the gun to Doyleton's place with you? No. I saw it lying on the table near where I was standing in Doyleton's apartment. But a bullet was fired from that gun. Maroney testified. Wait a minute. Maroney... Say... that gives me an idea. Do you think you could save me from... I don't want to try. I didn't shoot Doyleton. I didn't. Take it easy, Rogers. Look. Call the guard and have him get the warden here in a hurry. Tell him you want to make a statement. But what good will that... When the guard unlocks the cell door to let the warden in, I'll slip out. All right. All right, I'll do it. Oh, God! God! I want to see the warden. The warden! What has the blue beetle in mind? Who is Maroney? And what has he to do with this case?

There's also processed food, which has gone through a lot of changes in factories. Perhaps the best kind of food is homemade. Homemade food is food that is prepared at home in a traditional way by a real person. Now let's look at some verbs. Of course, the most common verb we use with food is eat. You can also use have, have lunch, have a bite of your sandwich, have some potatoes, and a more formal word is consume. When you eat, you first take a bite of your food.

Now, it is very nearly time to say goodbye and thank you, but before we go, I would like to welcome back to the stage the co-chairs of the conference, Melissa and Keith, who will join me up here now for some closing remarks. And then, importantly, also to find out what's in store in 12 months' time. Because while this conference may have flown past, preparations are already underway for 2020. So if you just bear with me for a moment, we've got all ready to bring this conference to a close. And please, for one last time, put your hands together for our co-chairs of the 2019 annual conference. Well done. Look at you with the stamina, having made it through, well done. It's hard to reflect on something that feels so immediate, and we haven't even finished. I think it's worth saying that the conference has gone well. We've been very pleased to host you here. I'm very aware there was a lot of University of Edinburgh content and colleagues here, and we did very well with some awards and prizes and celebrations, and I think it's probably inelegant to go on about that, but I'm particularly proud of all of the colleagues from Edinburgh who have contributed and made you all feel welcome in our home, which is gorgeous, and I'm glad that you've enjoyed the venues as well. Thinking back to, was it a year ago, that we started discussing the themes for the conference and thinking about the keynotes that we would invite and the kinds of themes and sessions that we would encourage, there has been many, I think we've chosen, I think we chose OK, there's been lots of presentations about data and analytics, many more than in previous years, and I think that that's clearly a coming theme for us all, and some gap between measurement and meaning that we need to continue to explore. There's a massive gap, I think, in the connecting physically and virtually, I feel like there's been a lot of participation online, particularly as you could tell that some of the people who were physically attending the conference were also connecting online or possibly from back in the residences or out and about around the city, and I think that's been a success. I always would encourage people to come to Edinburgh whenever possible, and for those of you who have come, hasty back, you're very welcome to come again. I would also, I think, recommend the experience of being a co-chair of this conference, I don't know if you're going to say anything about that as well. It is an amazing experience. I need to say thank you to all of the old staff, all of the volunteers, all of you who took part in the reviewing of papers, thinking about what we're going to do at the conference, thinking about the themes, thinking about the social program. I would recommend it to anyone who might be thinking of being a co-chair in the future, maybe if the conference happens again somewhere next year. When we leave here now, for those of you who are able to come across to the main library for a reception, we're hosting that on the sixth floor of the main library. If you come to the reception of the main library and ask for where the Centre for Research Collections is, we've got some wine and some nibbles, if you're able to stay. I think we have a special gift and thank you for Maron. Shall we do that now? We could not do this without Maron and her team, and you all know that. Thank you from me and the team and the 100 volunteers class who make this possible. Thank you very much. Thank you, Melissa. I don't have too much to add to what Melissa's already said. It's been a fantastic experience working with Melissa and Louise to bring this together. Under the guidance of Maron and Martin and the Alts team, a well old machine, and I kind of become conscious today, not sure why just today, but we've come to the end of our experience, but actually the planning for next year's event will have started probably months ago. So I think it's a real testament to the Alts team that they do this great conference year in, year out. I think the only thing I can add to what Melissa said is that lots of things make for a really good conference, but ultimately what makes for your conference experience is what happens when you walk into that classroom or seminar room or what happens when you come in here. And that's dependent on who's speaking, and that's dependent on the willingness of delegates and participants to get engaged, to have discussions, and to make the conference happen. And I think we were really fortunate in the quality of the submissions we received, and actually the willingness of our participants, whether you're here as a delegate or a delegate who's also presenting, to get engaged, to kind of speak to each other, to have some critical dialogue, to share good practice, and to keep to time, which most people seem to do. So I would just like to say thanks to all the participants and all the presenters, and then give yourselves a round of applause, please. Well, we're just going to thank our sponsors and exhibitors again. Without their support, it wouldn't be possible. And I wanted to echo and add one more thank you, and that is to all of you who've not just brought research and practice to this conference, but also your hearts. It really resonated with me that all of our speakers that I saw at the conference mentioned the people dimension. And as a professional body, we are all about our members and put people at the heart of educational technology and learning technology, and this conference has brought it back to me very poignantly that in whatever circumstances we operate, it is really care for each other that makes such a difference. And so many of the conversations I had at this conference were about people coming up to me and said, you know, I really learned a lot. There was a lot of knowledge sharing, but what I really took home was that it has real heart. So as the chief executive of Alt is my privilege to serve a community that has such a big heart. And I want to say thank you to everyone on behalf of the Board of Trustees and together with my colleagues for helping us keep that heart beating for another year. So thank you very much. As Melissa mentioned, we do hope that there will be another annual conference next year and I can reassure you that there will be. And it is now my privilege to welcome one of the co-chairs of next year's conference who has bravely made the journey north and is individually representing the co-chairs. So over to the not so mysterious anymore, Matt Lingard, one of the co-chairs for 2020. Thank you, Marin. It's really exciting to be here today. Firstly, thank you for your generosity in still being here today after three fantastic but ultimately very tiring as well days. It's great for you to have stayed right till the end and I will return that generosity by being as brief as possible. So the conference. How exciting. So these are the fantastic people I'm going to be working over the next year for Zana and Roger. It's a shame they couldn't be here today. But hopefully I can convey on my own the absolute excitement we have and the thrill of hearing from Alt that we've got the go ahead to chair next year. We really are excited and the thing that's brought us together and the reason we want to do it is Alt and is the conference and our experience over many years. My first conference, I had hair. So that was Sunday in 2002 and I know there are people in the room who were there. In 2002, I just started work as a learning technology support officer. It was the first job with learning technology in the title that I'd ever had and I suddenly discovered that there were other people doing the same kind of work and there was this huge network that I'd not been aware of in a previous job with doing learning technology. And if I think back to 2002, there is absolutely no way I could ever have imagined I'd be standing here today. And I was reflecting on that on the way up on the train and Alt is a huge part of the reason that I'm able to be here today. Everything I've taken from the community, the conferences, the local group in London, the hashtag and all the fabulous relationships I've built up through those last 17 years is why we all three wanted to chair the conference because we think it's such an important event for sharing and learning from each other. First thing, that's the date. No surprise there. We're in September. Make a note of it. So here's a map of where all the conferences have been so far. It's not in any of those locations. So if you wanted to go to Telford, I'm really sorry, but we're not going to Telford in 2020. There are a couple of kind of big spaces on that map. I'll take Ireland out of it. We'll just move Europe over there for now. But Northern Ireland, the east of England, the south, southeast of England and Wales, all big gaps. So it's a real privilege for me, despite having spent half of my life living where most of those green dots are, actually. For the last 20 years, I've been living in what I feel is the greatest city in the world. So I'll be welcoming you to London. It's the very first time I've been to London for the conference, and I'm hugely excited about it. We're going to be hosted by Imperial College. So we'll be in South Kensington down the road from the Science Museum, the Natural History Museum, the V&A, Hyde Park, and the rest of London all around us. So it's such... I hope it's going to bring you all to London. I really do, but I'm sure the last three days is what will bring you to London, because it's been a fabulous conference. I'm slightly nervous about doing this if I'm honest, but there are two things that have made me a bit more relaxed about it. The first is Marin and the team at ALT, who I know that's what makes the conference run and function, and I know they're going to be behind us along with the trustees. But the thing, as Keith was saying, that makes the conference success is the people. So this is a plea to get involved, join the program committee, come to London, put in presentations, and I really hope that I will be seeing you for many years' time, and thank you. I'll come through. Now you see that there will be a much travelling from Edinburgh to London for the next year, and we're really looking forward to welcoming many of you back. So now it's just for me to left to say thank you again on behalf of all of us in every way for which you have contributed to making our 2019 annual conference. We wish you safe travels, and we look forward to you being active in our community in the coming year. Thank you. And Smart Campus Technology.


the Narcissus Panic Mode. They end up in this situation where everything seems out of control. They go around in circles doing the same thing again and again expecting a different result doing the same things without achieving anything. Any conversations you have with them while they are in Panic Mode will just go round in circles. You will be wasting your time and energy trying to get through to them because while they're in Panic Mode they're not even listening to what you're saying. All they're really focused on is their own emotions. You can try to stay calm but that will only make them panic even more. They want you to take on their emotions only then can they relax only then can they stay comfortable and that is why they will try to project their emotions onto you they will try to shift the blame onto you and act like whatever went wrong is a fault or mistake that you have made when the Narcissus enters Panic Mode there is no telling what they might do they will often create many different opportunities to provide a false sense of fulfillment but there is no telling which opportunity they might choose when they are in this mode of behavior they can be very unpredictable they can also be very reckless they don't consider the risks they don't consider the potential consequences of their actions because when they're in Panic Mode all they're really focused on is their emotions and they are trying to manage their emotions through their actions which is a very dangerous thing to do nothing good comes from acting on weak, immature emotions but this is exactly what the Narcissus will do and it often causes even more problems when they are in this state because when our emotions are high our intelligence is low when we act on our emotions we're not thinking clearly we're not using logic or reasoning which then results in poor judgment when the Narcissus makes a poor decision they will not hold themselves accountable instead they will shift the blame onto you they will panic even more until they finally provoke you to react and then the whole thing just gets really messy it just gets really confusing you're stuck in fight or flight mode and you don't even know how or why you got there panicking over something that you never thought would bother you because you're around someone who acts in such an exaggerated way they want to get an emotional reaction out of you they want you to express their emotions for them because that is what relieves their pain and suffering it's just like a young child they cannot regulate their emotions on their own but it's a lot easier for the child to understand when they see you reacting to the situation it relieves the child's pain and suffering just as it does with the Narcissus Narcissus are very insecure they are very uncertain they are very anxious about themselves and that is why they are prone to experiencing panic mode they also have poor focus and concentration they get distracted very easily which is another thing that causes them to enter panic mode instead of focusing on a potential solution they're more focused on the problem they feed into it which then causes them to panic they feed into it because they're insecure they're not confident about themselves if they felt confident enough to be able to deal with the situation they would not panic they're experiencing fear and anxiety they feel as though they are unable to cope with the situation and that is why they cannot respond like a normal emotionally healthy person it all comes down to their lack of confidence in themselves they are very insecure that is why whenever they run into a problem or issue they feel like the world is collapsing around them they have no faith in themselves they have no self-sufficiency or self-reliance and that is why they are heavily dependent on you for their sense of security and stability they always panic to you and they expect you to take on those emotions because like a child they cannot deal with them on their own so they enter panic mode it's really nothing more than an emotionally underdeveloped person crying for attention because when they're in this mode that's all they really need that is the purpose of them entering this mode of behaviour it's because they need attention they need you to attend to them and as soon as you do that they begin to calm down but it also tells them what they need to do to get their way with you over time this behaviour will have an effect on you it will drain you mentally and emotionally it may damage certain parts of the brain such as the hippocampus and the amygdala this then affects your motivation emotional regulation learning, memory and focus you enter a constant state of fight or flight which can then cause you to develop panic disorder when you are around someone who is constantly in panic mode you end up becoming responsible for their emotions they expect you to attend to their emotions over time they become more and more relaxed while you get more and more stressed out it's almost like a personality swap and that is why these people are so dangerous to be around you lose your happiness and joy you lose the sense of liveliness and excitement that you once possessed and all you're left with is an empty shell of who you used to be thank you for watching I hope this video resonates with you please like, comment,
