My Eye Operation

Tuesday, October 02, 2007 Posted by Cecilia Loureiro-Koechlin 6 comments
Note: this story beats the I cut my finger story I wrote last year.

A month ago I had an eye operation. It was the first time and hopefully the last one too. Here I'm gonna relate you, briefly, all the incidents that happened that day and the days after. But first, I have to say that if you are under 15 you have to be accompanied by an adult to read this blog. :)

The reason for having this surgery was a pterygium in my right eye that was bothering me for over a year. I thought of having this done in Lima with laser. But being so far I decided to go to the NHS here in Britain. As usual I first went to my GP who, to my surprise, referred me immediately to an eye doctor. This eye doctor referred me again to another eye doctor expert in the frontal part of the eye. This last doctor said I could have the operation and it would be ambulatory (sort of like going to the dentist!). He booked me for the 3rd of September and asked me if I wanted general or local anesthetic. I said general of course!

On the 3rd of September Rodrigo and I got to the reception of the Eye Hospital and I was kindly received by a nice group of nurses. One of them was worried that I didn't speak English. Hehehe I said don't worry. A second nurse asked me if I could have local instead of general anesthetic. I asked why. She said because it is safer, and "our big lift isn't working so we cannot take you to the operating theater". (Bullsh....!) She said it was going to be quicker and would be able to go home in a few hours. I accepted.

The nurse walked us to a big room where I was assigned a bed. I changed to a white gown... and waited. In the mean time nurses came many times to offer us tea and biscuits, of course Rodrigo was delighted. When the time of the operation came a nurse came to collect me. We took the lift (????) and got into a sort of reception room of the operating room. There I met a nice nurse (he was rather camp!) He explained what was going to happen and told me jokes and made me relax. Then the anesthetist came and gave two injections very close to the eye. Looked scary but they weren't painful. Just a tiny prick. After 10 mins my eye went numb. The same feeling you have when you get an anesthetic at the dentist. I couldn't open my eye. In fact half of my face felt like a huge water melon. They took me into the operating room and put things to cover my face. The doctor put a metallic thing to open my eye and began to operate. You may be wondering if I could see. And the answer is YES. Although everything was blurred I could tell the doctor and nurses from the ceiling. I could see the needles, the scissors and other thingies... and I could hear the noises they made. The operation lasted about one hour. My neck went stiff and was hurting... Basically what the doctor did was remove the pterygium, then take a piece of tissue from another part of the eye to cover the hole left by the pterygium. When he finished he put bandage lens to cover my eye (like a contact lens but bigger and rectangular) and a patch on my eye. He gave instructions to the nurse to remove the patch in 1hr. I was taken to another room to recover. One hour later I walked and took the lift to the room, where my bed was.

Rodrigo was there waiting for me :) I felt numb but Ok. No pain yet. I laid on the bed and fell asleep for 20 mins. Rodrigo took a picture of me. Then I woke up and sat on a chair. Rodrigo took pictures of me. The nurse came to remove the patch... that was scary. Rodrigo couldn't take any picture :P. The nurse took the patch off my eye and asked me to open my eye!!!! Of course I couldn't. That is the weirdest sensation ever. It was awful. I opened my eye and I saw double. I could feel the bandage lens, and my eye began to water. The nurse gave me 3 drops and said I should use them every 2 hrs! Except at night time..... And if I felt pain I should have paracetamol. Rodrigo then took me home and gave me food :D I was really hungry and eating distracted my attention from my eye to my stomach. I went to bed and fell asleep.
I woke up at 02:30 with a lot of pain in the eye... I went to the living room, took 2 paracetamol and waited. I walked around the furniture for 3 hours. The pain didn't go. I sat in the sofa and thankfully I fell asleep for 1 hour. Woke up again with pain. This whole loop of trying to sleep, walking around things and pain lasted the whole day to the extent that Rodrigo had to ring the hospital. They gave me another appointment for 17:00.
We went to the hospital and saw another doctor.... well... Rodrigo saw him because I couldn't. I had my eyes closed. My right eye had been hurting and watering the whole day. And the doctor says "please open your eye" hehehehehe I tried but couldn't. I tried harder and I think I could open it a bit but not enough. So the doctor takes some magic drops and gave me one. In a second or two the pain disappeared!!! Why did the doctor not give me those drops instead of freaking paracetamol!!!!!!

Anyway I was afraid that my eye was infected but it wasn't. It was healing Ok according to the doctor. I asked him if he could give me stronger painkillers and he said well, you don't want ulcers, do you? ahhhhhhhhhhh

Well, those drops stopped the pain for the rest of the day and night. Next day I had no pain, just some discomfort in the eye, which lasted a few more days, until the doctor removed the bandage lens a week after.

I must say this: I was impressed by the service in the Eye Hospital and NHS. The nurses and doctors are first class.

What about software? hmmm... everytime I've been to the eye clinic (not the eye hospital) to see the doctor for check ups, the receptionist enters my name in the computer then she asks me my address and she says ok, go to the waiting room, blah blah, .... When I leave I go to the receptionist I give her the instructions from my doctor, she enters something in the computer and then she takes a yellow paper and writes the date for my next appointment.
Also, they had these TV/Internet screens by each bed. They had a metallic arm which allowed you to move the screen where you wanted. Only thing was that you needed your credit card to use it. :-/

Computer Agents

Monday, July 30, 2007 Posted by Cecilia Loureiro-Koechlin 3 comments
I am writing a paper on software development and structuration theory which has actually been accepted in the Journal of Systems Research and Behavioral Science (I am working on corrections now). The paper is based on my PhD thesis' contribution to knowledge (it sounds important but it isn't :P). To put it in short, simple terms, in my paper I explain how I developed a model of social issues in software development.

More in detail (read this if you have insomnia)

The model is situated within a theoretical framework of structuration of technology (you'll need to read Giddens and Orlikowski to understand this) and was generated from data I gathered from virtual communities of software developers (people like you who spend their time reading and posting in blogs and forums :P).

My model describes how developers' understanding of new situations (like new assignments) is dependent on their current mental structures, that is their past experiences and knowledge of certain practices. Giddens calls them social structures but because structures exist in the memory of people (and they come to life through human activity and interaction) I call them mental structures or preconceptions. So, preconceptions determine the way developers address new situations. That is, developers act on the social structures known to them to evaluate, design and implement software.

However, as new assignments possess new challenges (not every project is the same and neither is every developer), developers adapt their preconceptions to develop new software. This is a cyclic process as new situations will form part of developers' future preconceptions. Preconceptions and new situations carry out a number of human and social issues that the developers' have to deal with and address when they develop software. During my fieldwork I found out that the main sources of issues for developers where their own development environment, the practices or methodologies they had (or were forced) to use and their client organisations (we all have hated one or two users or maybe more?).

(Insomnia bit over)

Now, I submitted the paper and got positive feedback from the examiner. However I got one recommendation which I am dealing with at the moment. The examiner suggested I should address the issue of partitioning the software development task between human and computer-based agents. YES computer-based agents. Something like AI.

Ok if you don’t know what I mean by computer-based agents here you have an example. If you have ever been to amazon, you may have noticed the personalised suggestions you get there. That is a computer-based agent which tracks your preferences and purchases and by comparing other people’s preferences and purchases produces a list of suggestions. Although they are only pieces of software, to some people they may appear as humans. My examiner thinks we could produce computer-based agents to develop software.

I realise that by doing a PhD in management I have turned to the light side of the force. In my doctorate I study people producing software, and ignored the possibility that there can also be software producing more software. Software reproduction. Of course that would be another PhD and I am not interested. But, I wonder, how would software developers’ lives be if they had to deal with AI issues as well? Emotionless, unambiguous agents, but perhaps unpredictable like humans. Who knows???

Technology of the future: The Wee-dar

Monday, July 23, 2007 Posted by Cecilia Loureiro-Koechlin 5 comments
We went to Leeds last weekend. We had a great night out with our friends: lunch at a Portuguese, Transformers (yes, with Optimus Prime and the gang! not my cup of tea, but what can I do if I go out with big children!), Guinness Red (less bitter than the original), then dinner at La Tasca (acceptable tapas and red wine, good music and excellent environment).

When we were walking to the car park, we witnessed an incident. All of a sudden, out of the blue, about 10 police officers appeared and ran towards a small crowd of drunks (which were not us of course). They arrested a guy and tried to contain the small crowd that was gathering there. In seconds 3 or 4 police patrols and vans came with more officers!!! Seriously, it looked like a movie. We walked by and stopped to talk to other lurkers. A man who had been there since the beginning told us that the police arrested a guy who had been weeing in the street...

I've never seen such a display of force to arrest a wee-r. I feel protected now. I don't mind terrorists and floods as long as I am free from the wee-rs.

Anyhow, I was wondering what kind of system the police have to detect wee-rs so quickly. Do you think it is cctv? It may involve the use of advanced video and audio equipment as well as a powerful smeller. It must be a network that covers the whole city centre. Or perhaps it was one of the Transformers (one with a huge nose, i.e. wee-dar?). oh what a weekend!

The Aztecs, Bucephalus and Solzhenitsyn

Monday, July 02, 2007 Posted by Cecilia Loureiro-Koechlin 11 comments
I went to the pub last night with my husband and a friend. There we met a guy who asked us to look after his dog - Jack - while he went to the toilet. The guy, Mark, seemed nice, and the dog was very cute so we said yes, no problem. When Mark came from the toilet we gave him Jack back and continued our conversation. We were talking about the America cup and Venezuela. All of a sudden Mark came to our table and joined our conversation. He told me you look like a mexican indian! :s I said nothing.... and he said yes really you look like an Aztec, and I couldn't avoid laughing. I said I am not from Mexico. And he didn't listen. He kept on talking about the Aztecs. He said he saw a TV show about the Aztecs recently. He said something about the "last aztec" who was living in London :s He then asked me if I knew about Moctezuma. And I said just a bit, he was an Aztec king who was defeated by the Spanish. And he said you should know more of your history! Oh my God I am not Mexican!


Well, Mark continued with his tale about the Aztecs, and then he changed the topic to his favourite movie: ¡Viva Zapata! Again he asked us if we knew about it. I said oh yes the leader of the Mexican revolution. My husband said something about Marlon Brandon (in Viva Zapata and the Godfather) and Mark bought it. Mark liked Zapata's horse and he asked us if we liked it too. We said yes his famous white horse. And then my husband said: like Alexander's the great horse. And then the guy got more excited. Oh yes Bucephalus I love Bucephalus how wonderful horse... and Alexander the great... I love him! He told us stories about Bucephalus and got even more excited...

After a while, I don't know how, we ended up talking about Russian literature. My friend happened to know a book that Mark had read: The Gulag Archipelago by Solzhenitsyn. Solzhenitsyn was a russian dissident and in his book he denounces the structure of repression of the soviet state. Systematic abuse by Lenin and Stalin. Awful stories about prisoners in concentration camps, etc. Apparently that book was a bit depressing, but of course Mark loved it... My friend and Mark discussed the book for a while until Mark got a bit emotional. I could see his eyes turning red... and it wasn't the effects of the pint of lager he was drinking!

It was late (and Jack was getting very bored and impatient) so we decided to go home. We said bye to Mark and he asked us to say hi to him next time we see him. He said he might not remember us but that we should remind him of our interesting conversation.

Unfortunately, Mark did not know anything about software development, otherwise we could've had some fun discussing windows vista, agile methodologies, and the new iPhone!!!! (which by the way is internet enabled, has an amazing user interface, and a multi-touch screen... just beautiful) ... I'm such a nerd!

¡Viva México cabrones!

Cherie Blair y sus campañas anti-esclavitud

Wednesday, June 20, 2007 Posted by Cecilia Loureiro-Koechlin 5 comments
Hace unas semanas Cherie Booth, mas conocida como Cherie Blair vino a la universidad de Hull a dar una presentación . Su seminario fue parte de una conferencia a cerca de la esclavitud. Resulta que el primer tio que armó una campaña anti-esclavitud y finalmente logró abolirla, William Wilberforce, nació en estas inóspitas tierras de Hull. Y este año se cumplen 200 años desde la abolición,

La charla estuvo muy interesante y entretenida. La primera parte de la presentación se enfocó en la historia de la esclavitud.... claro la tía tiene mucho material, porque los ingleses fueron expertos en ese arte.... luego pasó a formas de esclavitud modernas, es decir como se ha transformado la esclavitud en nuestros tiempos (tráfico de niños o de mujeres, etc.) y luego todos los intentos del mundo "civilizado" para desaparecer la esclavitud de la faz de la tierra.

La presentacion y el teatro estuvieron impresionantes. Habian algunas personalidades locales en el público (nadie que uds. conozcan). El teatro es el salón mas grande de la escuela de negocios. Con super tres pantallas gigantes. Por ahi he visto a uno que otro profesor dar clase en esta aula con un micrófono inalámbrico de esos que se ponen en la cabeza, a lo Britney Spears.

Luego de la presentación, el público, incluyendo Cherie, se fue a la cafetería de la escuela. Yo no fui porque me vine a bloggear. Me cuentaron por ahí que por ahí vino una estudiante de la India a decirle que su charla le habia hecho recordar a los esclavos que tenia en su casa --- what!!!!

¿Y qué tiene que ver todo esto con Software o desarrollo de Software? pues casi nada, solo que la presentacion la hicieron en PowerPoint, jejejejeje.

¿Cómo se dice lluvia en árabe?

jejejeje... qué monse...


Ha estado lloviendo desde ayer en la mañana y hoy la cosa se puso mas fuerte. Mi calle está inundada, y ¡tuvimos que nadar para llegar al auto! Me pegué una super bañada... pero igual vine a trabajar.... "responsabilidad ante todo".

Nos han avisado a todos por correo que grabemos nuestro trabajo en la computadora seguido, porque puede ser que se nos venga una falla eléctrica general en todo el campus,... claro, por la lluvia....

Chequeen el video...



Esto me hace acordar de aquella canción que dice así:

♫ Que llueva, que llueva,
la bruja está en la cueva,
los pajaritos cantan,
las nubes se levantan,
¡que si!
¡que no!
que caiga un chaparrón,
con azúcar y turrón,
que rompa los cristales de la estación,
y los tuyos si, y los míos no. ♫

(Chata, esto no tiene nada que ver contigo, no te sientas aludida ¡ah!
mmm, quizás debería traer al Danicito aquí a ver si le gusta esta ducha gigante jejeje)

What do I know about e-learning?

Tuesday, April 24, 2007 Posted by Cecilia Loureiro-Koechlin 5 comments
Very little but here you go.

Today I was talking to my boss about websites, google and discussion forums, and my weblog came into the conversation somewhere. I realised I hadn't posted anything since February! not because I had nothing to say but because I forgot.

I am gonna update you on my latest activities. Last week I attended a conference in Hawaii!!!
But hey! Don't get too excited I didn't go to Hawaii, it was an online conference and I only needed my laptop to attend the seminars. The name of the conference is Technology, Colleges and Community and it is designed for university and college practitioners. 99.99% of the presentations were focused on teaching and learning, topics which are not in my field of expertise (if I have one). I decided to attend the conference for three reasons:
1. I'd never been to an online conference before. I was interested in seeing how they worked, specially the software tools, chatrooms, webinars, etc.
2. Some of the seminars where about the use of social software (which is a topic that fascinates me) in teaching.
3. The project I am working on is focused on e-mentoring and e-learning. The online community I am administrating supports students learning by providing a place for discussion and with relevant reading material. I was interested in knowing what other people are doing in similar situations and maybe get new ideas for our project.

So, what did I learn in this conference?

I found it interesting to see how academics reinvent software tools and make them work for their needs. Most of the presentations I attended focused on the use of social software, such as weblogs and wikis in online courses. I enjoyed one about using Google Notes, and Google Docs & Spreadsheets for collaborative work. So simple but still very few people use tools like these.

In one seminar the presenter explained how she used blogs and wikis within the blackboard environment. So in some instances, students were asked to write personal journals (weblogs) and in some others students were asked to produce a group report in a wiki. Some of the weblogs were public so the other students could read them and comment on them. To make their weblog public students had to be very confident on what they were writing and not be afraid of criticism. Of course the teacher had access to all of them.

In another seminar the presenter showed some data from a study he was doing about assessing online discussions. From the 50 (I think) online courses he studied most of them were using discussion boards as a way of assessing students learning. Students were asked to contribute at different moments in the course and with a minimum number of posts. The designers of the online courses stated that they encouraged discussions in class, because they are a way of motivating students to think, reflect on their ideas, articulate and share their ideas. Someone said this: "Discussion is where class happens!". I like it. If you don't make your students interact online then the online course would look like a correspondence course!

The most entertaining seminar for me was this one about using anime (Japanese cartoons) to teach Japanese. The guy, who said he
liked paperless media, made his students write subtitles or captions for the anime series with a special software. He also used wikis and bulletin boards to make his students work in groups.

In our project's virtual community tool students participate and discuss about the topics they are assigned. Some of these topics are assessed activities so it is compulsory for them to post at least one contribution in those threads. However, I've noticed that they participate with the same enthusiasm in the non-assessed activities. Since the beginning of the course I've seen an improvement in quality in content of their online interactions. They know they can take their time to think and design their contribution. Also, students are more confident at using the software tool, they respond to each other posts, they are able to attach extra documentation or refer to external websites. Basically, what I am seeing there is the formation of a virtual learning community, and I feel very excited about that.

By the way, the software we used to attend the webinars is called Elluminate. Here you have a screenshot (click on the picture for a larger version). I attended the seminars from home, using a slo-o-o-o-o-o-o-w dial up connection, and had very little problems. (I experienced some delay problems in the anime presentation, the audio was faster than the actual presentation, so it felt unsynchronized). The PowerPoint presentation is shown in the main screen in the right-hand side. If the presenter opened a website in a browser, the browser will appear on top of (inside) the Elluminate screen. The list of participants is shown in the top left-hand side and below it there is a chat room. Whenever we wanted to ask a question we could raise our hands by clicking on the "raise your hand" button. The presenter would see that and "give us" the microphone. If we didn't have a microphone we could use the chat room. In all the seminars I attended I noticed that discussions in the chat room ran in parallel with the actual presentation. Sometimes the presenter would interrupt his/her presentation to make a comment on something that had been said in the chat room. Seminars only lasted 45min each and at the end we could express our gratitude by "applauding", cool!

Matching Software

Monday, February 12, 2007 Posted by Cecilia Loureiro-Koechlin 5 comments
Last year, just before christmas, I entertained myself programming a small application in Visual Basic for Ms Access 2002. I developed a matching software to pair mentors and students in our project... (see 2 - 3 posts below)

For our project we are asking mentors and students to complete an online questionnaire about their experience and values (which I designed in our online community tool). The data from the questionnaire (tab-delimited files) are imported into the matching software. The application then calculates a matching mark for all the mentor-mentee combinations. The more similar values and experience mentor and student have, the higher the marks. Marks are shown in the grid (click picture to see a larger version).

The next step in the process is manual. My colleague and I decide which mentor goes with which student by clicking on the marks. The software highlights the mentor and student so they cannot be chosen again. (Only one studefor each mentor and one mentor for each student.) Of course we will choose the highest marks possible. We are doing this bit manually to avoid having the last pairs getting the worst marks. So by choosing ourselves the pairs we will try to balance the scale and be fair. The list of pairs chosen is shown in the bottom of the screen.


The whole thing looks simple. The only thing though was the $£%@# grid. I had to draw it! 25x25 = 625 boxes :( one by one!! I had all the resulting matching marks in an array and needed something to display them. The only thing that occurred to me was that grid.... I asked some "experts" (Pastelito, Tiki, JLo¼...) in visual basic, .net, java, etc. how I could draw 625 boxes in one go but got no answer...

The software works so I don't mind the time I spent in each box :P but if you happen to know a shortcut or a better way for doing this feel free to contribute in this blog. If you have no clue, just tell me whatever you are thinking....
