Hi Kat, This simple example of organising space illustrates that design is not fixed but adapts to changing requirements. The perfect organisation for one activity at one time may be unsuitable for another subsequent activity. Best wishes for the rest of the course - Jeff

What do you think? Do you know of any examples of design leadership? Do you agree that everyone is able to design or use design in their everyday life? The last thing I designed was my desk. I'm always moving things from here to there, adding useful things and removing things I don't use much - I am constantly searching for the 'perfect desk layout'. What was...

What do you think? Do you think that ordinary people with no experience of design projects can take initiatives and work with others to create valuable new community amenities? For example, can a busy Mum help create somewhere for a toddler playgroup? Could lonely elderly people contribute to community-led design? Or are people too busy to participate? Or...

Hi Everybody. Welcome to the second part of the course.
It is now nine months since we opened this course. Over this time we have learned a lot about COVID-19. The announcement of effective new vaccines is a game-changer. But so are the new variants of the virus.
In the UK, after 14 million vaccinations there is great pressure to cease the...

Hi Everyone,
The course has now been running since April and a lot has happened in that time. This includes the recent announcements of effective vaccines. And new more transmissible forms of the virus.
In the UK more than 14 million people have been vaccinated. But to beat the virus we need a high level of vaccination in every country of...

@CliveSims Hi Clive. Bruno Latour makes a distinction between "ready made science" and "science in the making". The ready made science of biology, epidemiology, etc. have given us vaccines in an astonishingly short time. The social, economics, organisational, etc. science of how to handle the pandemic is, I think, science in the making. In this context we are...

There are very interesting comments here. The consensus is that hoping for herd immunity without a vaccine is not a viable policy for most countries. Since April when this course started, in the UK we have seen the first wave (that did not overwhelm our Health Service) and a second wave with a new more transmissible form of the virus (that in the UK do...
-
Hi Shirley. I agree - herd immunity is the goal and the new vaccines can help achieve this. Without a vaccine the health service would be overwhelmed, as we are beginning to see in the UK with a new more transmissible strain. 'Flattening the curve' helps to spread the demand on the health service over time. Like you, I am in favour of funding the health system...

Hi Nourhan. Iain is referring to a mess made by the UK Government over grading national examinations for 15-16 year olds and 17-18 years.

It was decided to grade the children's exams by an 'algorithm' that... -
Jeffrey Johnson replied to Eline Ressa
Hi Eline, In the UK policy has changed from trying to get business going again to severe lockdown to try to control the virulent new strains of the virus that have emerged over the last week or two. Let's hope it works. Best wishes - Jeff
-
Hi Karen, A few weeks ago it seemed that the new vaccines would allow us to control the pandemic. However new strains of the virus have emerged in the UK causing a reversal of policy to relax the lockdown regulations for Christmas. It seems we never learn to expect the unexpected.

Hi Jo. In the Uk we are discovering that R varies greatly in time and geography. It is now becoming more common for figures to be quoted in terms of cases per thousand or hundred thousand in an area. For example, the statistics for Milton Keynes are 303 cases per 100,000 people in the latest week 5 Dec-11 Dec. I live in a village just South of Milton Keynes....

Hi Jo, Welcome to the course. In the UK we are seeing an increase in the number of cases, and there is some concern that relaxing the lockdown rules for Christmas will result in a third wave in January. Good luck with the course - Jeff

Jeffrey Johnson replied to Alex Hoare
Hi Alex, Agent-based simulations can be used to investigate social behaviour. Schelling is frequently quoted as an early example. As Victoria suggests above, the simulations do not necessarily lead to valid conclusions. But they make clear the assumptions and the consequences of the assumptions. Disagreements on the interpretation of the model are normal and...
-
Jeffrey Johnson replied to Victoria Morgan
Hi Victoria, Schelling's argument is that ghettos do not necessarily reflect racist views but could result from a mild preference for not being racially isolated. But, as you suggest, 'could' does not preclude that 'mild preference' including wanting neighbours who won't throw bricks through your window. Adam Rutherford gives deep insights into against racism...

Jeffrey Johnson replied to Tony Samson
Hi Tony, What you are doing is very interesting. My thoughts on the usefulness of R are similar to yours. Please use the email address anna.unitwin@gmail.com to send me a copy of your graphs. This may be a good way to investigate the possible outcome of the current UK policies. WIth many thanks - Jeff
-
Hi Tony, I agree that R0 (or R) is not a very good statistic for managing the pandemic. R0 is defined to be the rate of infection divided by the rate of recovery at the beginning of an epidemic. R starts as R0 but changes as behaviour and policies change. R changes with many things including geography. Your approach is very interesting and I would like to...

Jeffrey Johnson replied to Pepe L
Hi Pepe, Deaths are not so much an afterthought. The SIR model can be extended by assuming a portion of the infected people will die rather recover. This assumes that those who die and those who survive infect others in the same way. This is probably not true since those taken into hospital are isolated with medical staff (hopefully) wearing effective PPE, and...

Hi Thomas, I find thinking in terms for these graphics is more useful than talking about the R number. The graphics reinforce the idea that if you reduce the number of your interactions then you reduce your chance of getting the virus. Also they show how very quickly infection spreads in the exponential phase. I think this is not well understood and some...

Hi Mary, This is a nice example. Complex systems are not entirely unpredictable. You can't make a point prediction that lunch on a particular day with be a particular price. However you can do some sums and forecast the likely cost between limits, for example "it will be about £20, not less than £15 and not more than £25" and that is useful for policy...

@SYEDADEELHUSSAIN Hi Syed, I am just reading 'Science in Action' by Bruno Latour. He makes an interesting distinction between 'ready made science' and 'science in the making'. The discovery of 'unknown unknowns' through computer simulation is very much in the category of science in the making. Incidentally, I think we discover unknown unknowns by through...

Jeffrey Johnson replied to Brian Gofton
Hi Brian, I think that the numbers are inaccurate because front-line medics and their administrators give a lower priority to data collection and reporting than caring for patients. I agree with the thrust of you question - since reliable data is so important for policy why don't we have better systems to do it. It would be possible to have extra staff in...
-
Jeffrey Johnson replied to Thomas Hedley
Hi Thomas, Your risk assessment is a very interesting policy requirement. Common sense is very important. So the first question is "what is the policy intended to achieve". Presumably "no infections". According to Government guidelines a necessary condition for this is social distancing and wearing masks. etc. etc. I'm sure you've been through all this. I love...
-
Hi Syed, You make many interesting points. Since they run on computers most of our models are algorithmic. They may give different results for the same inputs by using random numbers (Monte Carlo methods, as you mention in another post). This enables possible futures to be explored through large populations of outcomes from the model. The statistical...

Hi Peta, I have also noticed that people do not always respect the one-ways systems in shops and supermarkets. Like you I don't like like to be too close to strangers, even when I'm wearing a mask. I think the government could explain better how the virus is transmitted, e.g. short animations on the TV and internet might help. Best wishes - Jeff

Hi Jiahsin, As you say COVID-19 is a terrible thing. And I agree that vaccination is the best solution. It seems a number of vaccines will soon be available. I think that some people in rich countries understand very well that we have a responsibility to provide vaccination for poorer countries. The pandemic affects us all. Before vaccination becomes a viable...
-
@VictoriaMorgan Hi Victoria, Yes, you are right. R0 is very dependent on social behaviour, e.g. Italians are more physical than Brits, Japanese people bow rather than shake hands, young people like house parties, crowded pubs and discos. The important thing is the number of contacts a person has. Decreasing the number of interactions reduces the probability of...

Hi Steven, I believe a lesson from COVID-19 will be that policy based on science gives the best outcomes. Science is not infallible - the traditional scientific method says that when a theory becomes inconsistent with observation that theory must be rejected. It's more complicated for multidisciplinary socio-technical systems like COVID where policy involves...

Hi Clive, I agree that test-trace-isolate has not been as effective as it might have been in the UK. About 1.3 million people are currently recorded as having been infected in the UK.

Hi Iain, Winston Churchill said democracy is the least worst form of government. We get the politicians that people vote for.

Ultimately politicians must decide what to do. ...

Jeffrey Johnson replied to Clive Sims
Hi Clive, To date about 1.2 million people have been infected in the UK, which means that about 65 million people have not been infected. Without a vaccine it could take much longer for the epidemic to die out. Treatment is important as you suggest, and it has improved a lot. Let's hope the current lockdowns will be successful.
