Vacanza a Roma - food

In a post some time ago I promised a few more details about a trip to Italy.  As usual I took much longer than planned to deliver on that promise...

One of the things most Mediterranean countries are known for is their food.  In the past I was not overly impressed by Italy's food and often jokingly remarked that they didn't even know how to properly prepare pizza.  I guess my previous opinion was based on the class of eateries I could afford to eat at during those trips to Italy.  This time around proper street restaurants were an option - and while they are really still beyond my financial means I had to reverse my opinion on Italian food.  They know how to cook!

It seems one of the secrets is their use of fresh produce.  Our journey therefore starts at Campo de' Fiori where merchants offer their produce, including fruit
and berries
that exude freshness, nutrition and colour.

Campo de' Fiori is a public square where, amongst others, heretics - such as those who proclaimed the sun to be at the centre of our universe - were publicly executed.  However, for the past almost 150 years it has been best known for its morning markets.  Despite the fact that the stalls look like temporary structures  modern electronic equipment is used for weighing, payment and other functions.  Landline phones are even installed in some of the stalls.

The customers seem to be satisfied - almost serenely so.

Some of the produce makes its way (perhaps not from Campo de' Fiori) to the local shops and restaurants.  This delivery is being made just down the street from the Trevi Fountain.

The restaurant in the picture below was just opposite our hotel.  It was interesting to observe how they displayed various types of food throughout the day in their window - depending on the time of day.  It was also interesting to observe how potential patrons would "window shop" and decide whether to eat here or something else based on the food that they saw.  If one decided to eat here one would typically pick a dish, from which they would remove or cut a piece and weigh it to determine the price.

The food was delicious everywhere.  Consider, for example, a tomato and feta pizza (with olive oil, rather than melted cheese).
Or consider just a simple tomato salad.
The Italians do indeed know how to eat...

On 13 June 2017 Dira Sengwe recognised the contribution of my late wife, Dr Mariëtte Botes, to the struggle for a proper response to HIV/AIDS by naming her as the recipient of the bi-annual Dira Sengwe Leadership in AIDS Award.   I accepted the award on her behalf at the 8th SA AIDS Conference in Durban.

The magnificent Dira Sengwe trophy

According to Prof Jerry Coovadia, chairperson of Dira Sengwe, the Leadership Award was instituted "in order to recognize exceptional contributions by individuals or organizations in the country in the response to the HIV epidemic."
Dira Sengwe ("take action") is an NGO formed by the organising committee of the XIIIth International AIDS Conference which was held in Durban in 2000.  This was at a time when the South African president publicly doubted that HIV was the cause of AIDS and his minister of health advocated the use of natural remedies, such as African beetroot and garlic as cures for those who were ill.  The year 2000 was seminal year in South African medicine.  Predident Mbeki's speech at the International Conference was inspired by his doubts.  He also convened his infamous AIDS Panel that boosted the egos of the HIV/AIDS denialists who were invited.  These denialists now had official "recognition" as members of Mbeki's AIDS Panel.  Scientists and doctors responded with the well-known Durban Declaration that affirmed the scientific findings about a causal links between HIV and AIDS.  In the public sphere the battle between NGOs (notably the Treatment Action Campaign and the AIDS Law Project) on the one side and government on the orther began, with puclic rallies and court cases being the most prominent manifestations of these battles.  Around 2002 government faced enough pressure to reluctantly begin a change of policies, but it was only after the recall of President Mbeki in 2008 and President Mohlantle's immediate decision to appoint a new minister of health that government's policy changed effectively.  A decade was lost during which thousands of people unnecessarily died from AIDS-related conditions and a next generation was born with HIV transmitted from mother to child.

One of Dira Sengwe's primary goals is to record the history of this particular struggle and remember its heroes.

In the mid-1990s an HIV/AIDS diagnosis implied death (except for a few with access to wealth).  Most doctors preferred to avoid such incurable illnesses.  However, a handful of pioneers realised that the role of the medical practitioner is not necessarily to cure; a terminal illness does not mean that quality of life should be abandoned.  While AIDS was terminal, the associated medical conditions could indeed be treated in a manner that extended quality life for as long as possible.  In the eraly years these pioneers began treating HIV+ patients symptomatically, with quality of life as an explicit goal - which also happened to extend life in many cases.  More and more antiretrovirals were being developed, but costs of such medications were prohibitive.  Mariëtte was one of those pioneers who did what she could for those who needed it.

Over time a new opportunity emerged.  Pharmaceutical companies who developed antiretroviral medication had access to patient populations for their phase 1 and phase 2 trials during which the safety and efficacy of medications were established in small sample groups.  However, they needed larger groups of patients for their phase 3 trials where the efficacy of the medications could be demonstrated and extrapolated to the general population. South Africa was an ideal setting for such trials because good medical facilities were available, skilled physicians were present, HIV was rampant and few of those infected ever had access to any HIV medication. From the patients' perspective those who qualified to participate in the trial at long last had access to such life-saving medication. (Readers who have questions about using clinical trials to provide access to treatment are referred to this page of clinicaltrials.gov.)

Mariëtte succeeded in participating in these trials, which provided access for patients at the Immunology Clinic of Kalafong Hospital in Pretoria under the auspices of the University of Pretoria. Providing access was already a significant achievement, given the official climate at the time. However,  the personal price she would have to pay only emerged later.

Who hatched the plan and why the various participants became involved in the plot that was to evolve, will probably never be answered in full. However, the aim of the plot was clear: discredit a proper medical response to the pandemic. A certain Vivienne Vermaak, who was a producer for MNET's national current affairs TV programme,  Carte Blanche, was also a self-proclaimed HIV denialist who posted her views on the (so called) HIV dissident fora.  She also previously produced programs based on her convictions for Carte Blanche. At some point she started filming her new project. In parallel, a vociferous politician was approached who quickly concluded that "a nest of abuse  and exploitation" was uncovered by this politician at Kalafong Hospital.  She who proceeded to inform the press accordingly. Somewhat later the Carte Blanche programme was flighted. In modern parlance it would be described as a masterpiece of fake news.

(24 July 2017) still portrays the fake news

A complaint about the fabricated Carte Blanche story at the Broadcasting Complaints Commission of South Africa eventually led to a retraction broadcast by Carte Blanche. MNET was, however, adamant that they could not be forced to apologise for their actions.  I wrote a letter that debunked the entire programme. However,  MNET's lawyers soon indicated their "wish" that I should refrain from distributing the letter further and expected me to send retractions to those to whom the letter had already been sent. When I protested that I could prove every claim I made in my letter, their response was brief: It does not matter. Unable to fight a team of corporate lawyers I had to comply. The result is that Carte Blanche's fake news report is still freely available on the Internet,  while my critique was successfully suppressed.

News headlines continued to intermittently report on the "abuse". The University of Pretoria,  afraid that its image might be tarnished, convened two commissions of enquiry. The first was an internal investigation that found no irregularities and confirmed that the correct procedures and ethics standards were followed at all times. However,  the University also realised that an internal report would not be of much use if the University was accused of any irregularities. A second investigation was therefore commissioned - this time to be conducted by respected Prof Sas Strauss from Unisa. This investigation also found that the particular study was conducted in a professional manner following the widely accepted international ethics standards for such studies. However, in an interesting twist, the University realised that it (the University) was not mentioned in the newspaper stories and decided not to become involved in a public manner. Mariëtte was therefore left to fend for herself.  Mariëtte often joked that she was "rescued" by the Hansie Cronje cricket match fixing scandal, which, in the year 2000, ended her term as the source of "scandal" in newspaper reports.

However, the end of newspaper reports was not the end of the saga. A biography of politician, Patricia de Lille was published in 2002. It listed De Lille's role in "exposing" the clinical trial as one of her important achievements as a politician. In particular it named various patients which it claimed complained about their treatment as participants in the now infamous clinical trial at the Immunology Clinic at Kalafong Hospital, which obviously revealed the implicit HIV positive status of these individuals to the world at large. Some of these individuals became victims of abuse in their communities after this. Three women, in particular, wanted their names removed from the book to minimise further abuse. They were referred to the legal aid clinic of the University of Pretoria, which was initially eager to assist. However,  De Lille, the author and publisher of the biography defended the publication of the names on the fact that the office of the Registrar of the University of Pretoria provided Vivienne Vermaak - a journalist - with a copy of Prof Strauss's report.  From this they inferred that the names were released to the press, and could therefore be published freely. For the Legal Aid Clinic this signalled a conflict of interest and they withdrew their assistance from those who claimed to have been harmed by the publication of their names.

The complaint was then referred to the Aids Law Project (ALP), which was based at the University of the Witwatersrand.  The ALP sought relief on behalf of the complainants, and eventually the case was heard in the (then) Johannesburg High Court. This court accepted the defence's grounds for publication of the names. Permission to appeal was refused by the High Court and was also later refused by the Court of Appeals in Bloemfontein. Eventually the Constitutional Court granted leave to appeal.  The highest court in the land at long last found that that the right to privacy of the complainants was indeed infringed, ordered the removal of their names from all unsold copies of the book and awarded a modest monetary amount for damages to the complainants.  Seven years had passed since De Lille initially accused Mariëtte from abusing patients until the Constitutional Court ruled that De Lille, the author and the publisher of the biography had infringed the rights of those whom De Lille claimed to represent.

Extracts from the Constitutional Court judgement

While this entire saga continued for seven years, Mariëtte did not linger while waiting for it to conclude. In the ALP she found a reliable and respected new ally. Over the many years that followed her initial discussions with the ALP, she did not hesitate to refer matters to the ALP where the rights of HIV-positive patients were infringed - and a call from the ALP to the relevant medical fund, employer or other offending party typically immediately resolved the matter in the patients' favour. In fact, the need to call the ALP was in most cases replaced by just mentioning that she would refer a specific matter to them. Over time she became one of the authoritative voices on the treatment of HIV.  She became involved in drafting treatment guidelines, was employed by medical aids to help decide complex treatment questions and acted as expert witness in HIV-related court cases. There was clearly no question that she fought the battle on the side of HIV-positive patients every day and everywhere.

Despite these significant (and sometimes visible) activities, what I experienced as her most important role became clear almost every time we went shopping. Almost always some patient recognised her and introduced her to his or her friends, colleagues or family members. In the vast majority of such introductions she was introduced by the patient as "the doctor who saved my life."

It is fitting that Dira Sengwe recognises the difference made by someone who most often fought it on a daily basis in the trenches.

Mariëtte passed away on 24 February 2017.  Today, 24 July, five months after that tragic day, is another suitable opportunity to celebrate her achievements.  It is a fitting day for a post about the Dira Sengwe Award, even though the award was made six weeks ago.

Apps and privacy legislation

One privacy benefit of app stores is that they generally inform the app user of the rights or permissions required by the app.  Sometimes the need for specific permissions are obvious from the purpose of the app.  Sometimes app authors explain why they need specific permissions (and one can then decide whether to trust such an explanation or not).  Often enough I decide that the permissions required by an app outweighs its utility (for me) and I keep on using the old version or, more often, uninstall the app.

One of the harder choices that some time ago confronted me was an upgraded app from my bank that requested the permissions in the screenshot below.

Of course the right to use certain features of a mobile device does not mean that the app uses those features to collect any personal information.  However, the permission provides the app with the ability to collect such information.  In the privacy literature the notion of a data controller is well known.  In the South African Protection of Personal Information (POPI) Act (2013) a record is "any recorded information" "(b) in the possession or under the control of a responsible party" [emphasis added] (c) "whether or not it was created by a responsible party", with the responsible party being the party that "determines the purpose of and means for processing personal information".  Processing is "any operation or activity or any set of operations ... concerning personal information, including" (b) using it.  Hence it seems reasonable for me to expect that privacy legislation provides me with some protection when some party obtains control over private information on my device.  At the time of writing this post, the major South African privacy legislation is not yet in effect, but what the legislator has in mind in clear.

There are two obvious limitations to the protection one can expect from privacy legislation.  Firstly, privacy legislation often first and foremost attempts to protect the privacy of those who live, work and/or transact in the jurisdiction where the law applies, so not all apps would be guided by the same norms.  Secondly, one should certainly not be obliged to accept the permissions requested by the app - uninstallation should remain a viable option.

Wild animals in the streets of Africa

When people hear I am from Africa a fairly common question is whether we have wild animals roaming in the streets.  Of course, the answer is: No, we keep them on a tight leash.

08 April 2012


Towards the end of 2011 my three nephews competed in the South African finals of the FIRST LEGO League (FLL).  I haven't yet exercised my bragging rights as their uncle, so here goes.

The FLL competition consists of several aspects, but the highlight is arguably the final phase where a robot constructed from Lego blocks have to complete a few tasks on a themed track.  In 2010, for example, the theme was Body Forward, and the track included tasks to assemble parts of a body, emulate certain body movements, and so on.  Given that 2010 was the year of the Soccer World Cup it was particularly apt  to get a model of a human leg to kick a tiny soccer ball onto goal posts on the track.  Research about the theme (outside the world of robotics) and a presentation on their findings is just one other facet of the competition the teams have to complete.  But, in 2010, disaster struck my nephews' team when the robot forgot its program and wandered aimlessly across the track.  (It happens when a robot with volatile memory loses power for a moment...)  So, let's not blog further about the 2010 competition.

In 2011 the competition was a different story!  This time armed with robots with non-volatile memory my nephews were members of two different teams that tackled the theme Food Factor.  The 'older' team (from 2010) called themselves De Bearz.  The 'younger' team therefore decided they had to be 'cubs', but never agreed on spelling.  So, the team's kit used every combination of De/Da and Cubs/Cubz (with and without spaces between the two words) somewhere.

Much of the competition takes place outside public view where the teams, for example, have to present their research to the judges.  The robot runs are open to the public and take the form of a typical sporting event.  The robots' actions are displayed on huge screens so that spectators can clearly follow the runs. Two members of a team are allowed to touch the robot (under certain conditions) while it is completing the track; the rest of the team act as cheer leaders trying to cheer their team (or their robot?) to victory.

The first picture shows De Cubz in action on Table B.  (Other teams are competing simultaneously on tables A, C and D.)  The clock is still at 230 indicating that this particular run has not yet started - the full two minutes and 30 seconds for it remain.  The two members at the corner of the table are the ones who will be handling the robot under the watchful eye of the judge standing towards the other corner of the table.  The nappies the team members wear are part of the team 'uniform' they chose to indicate that they are only cubs at this point.  My nephew, Paul, is the one holding the De Cubz sign as part of the cheering squad behind the white line they are not allowed to cross during the run.  (Should I have publicly admitted that the person holding the sign is family?)

And the run starts! Eight seconds into the run some members cannot bear looking.  (Pardon the pun...)  Others seem to be rather concerned.  And a few are just focused on the task at hand.

With just 33 seconds remaining, and adrenaline levels elevated, it seems the team is excited about what their robot is doing...

In the next picture the other team, De Bearz, are setting up their robot while a judge is looking on.  My nephew, Francois (centre), is exercising his divine right to touch the robot.

And they seem to be off to a good start!

But sometimes robots do odd things.  Even the team's mascot looks sad.

Long story short: De Bearz' robot did not loose its mind again and performed quite well.  They have much to be proud of.  And the newcomers, De Cubz?  They shot past their senior fellows and finished second in the competition!

My nephew who has remained invisible thus far is Karel - the fifth person from the left in the row at the back in the picture above.  He was team mentor for De Cubz.

Now it's off to Germany for De Cubz to represent South Africa internationally.  (The team who finished first will also participate internationally, but I never claimed that this blog post would be unbiased - so I will not say more about them.)

If you are like me you only have one burning question remaining at this time: Is it possible to take those trophies - built from Lego blocks - apart and build something else with them?  Sadly, the answer is no.  Somebody glued the blocks together to make the trophy endure...

Let's hold thumbs for De Cubz in Germany.  May they make South Africa proud!
