Meet Bishop Onyango First Female Anglican Bishop In East & Central Africa

Published

on

Kenya’s Canon Emily Awino Onyango has become the first female Anglican bishop in East and Central Africa after her appointment as Assistant Bishop in the Diocese of Bondo.

She was the second woman to be ordained a priest in the Anglican Church of Kenya.

Bishop Emily’s appointment was unanimously approved by a Special Synod of the Diocese on September 12, which was presided over by the Bishop of Bondo, Professor David Kodia.

In a sermon drawn from Matthew 9: 35-37, the Bishop Emeritus of Maseno West, Dr Joseph Otieno Wasonga, urged Christians to pray to the Lord of Harvest for more workers with the right skills, resources and spirit to fulfil his purposes “as the harvest is plentiful but with few workers”.

Bishop Emily Onyango is a scholar and researcher and currently works as a senior lecturer at Saint Paul’s University, where she teaches Church History in the faculty of Theology.

She is the chair of The Africa Centre for Biblical Equity (TACBE), a Langham scholar – one of the leading evangelical team of scholars and founder member of the Circle of Concerned African Women Theologians.

She obtained her doctorate from the University of Wales in the United Kingdom and worked under Professor J Lonsdale on the history of women’s Education in Kenya.

She obtained her Master’s Degree from the Asian Centre of Theological studies and a Bachelor of Divinity from Saint Paul’s United Theological College – the precursor to Saint Paul’s University.

Bishop Emily has been in ministry for over a decade, starting from the ministry of Children in the then Diocese of Maseno South. She was made a Deacon on 29 July 1984 and priested two years later in December 1986.

In February 2018 she was appointed a Canon in Bondo Diocese.

Her teaching ministry started at Saint John’s School of Theology in Kokise, where she served as Academic Dean and acted as the Principal.

She later moved to Saint Andrews Kabare and served as lecturer, Academic Dean and Vice Principal. From Saint Andrews Kabare she was appointed Lecturer and Dean of Students in 1999.

Bishop Emily’s Scholarship spans many areas within mission and church history. She has authored and edited several volumes and articles in different books and journals.

Her books include For God and Humanity: 100 years of St. Paul’s United Theological College and Gender and Development: A History of Women’s Education in Kenya.

In her new role Bishop Emily will take on responsibility for the training of clergy, women’s ministry within the Church, and gender issues, including the empowerment of boys and girls; and tackling gender-based violence.

Meet Covid-19 Data Superstar

Published

on

Spring 2020 brought with it the arrival of the celebrity statistical model. As the public tried to gauge how big a deal the covid-19 might be in March and April, it was pointed again and again to two forecasting systems: one built by Imperial College London, the other by the Institute for Health Metrics and Evaluation, or IHME, based in Seattle.

But the models yielded wildly divergent predictions. Imperial warned that the U.S. might see as many as 2 million Covid-19 deaths by the summer, while the IHME forecast was far more conservative, predicting about 60,000 deaths by August.

Neither, it turned out, was very close. The U.S. ultimately reached about 160,000 deaths by the start of August. The huge discrepancy in the forecasting figures that spring caught the attention of a then 26-year-old data scientist named Youyang Gu.

The young man had a master’s degree in electrical engineering and computer science from the Massachusetts Institute of Technology and another degree in mathematics, but no formal training in a pandemic-related area such as medicine or epidemiology. Still, he thought his background dealing with data models could prove useful during the pandemic.

In mid-April, while he was living with his parents in Santa Clara, Calif., Gu spent a week building his own Covid death predictor and a website to display the morbid information.

Before long, his model started producing more accurate results than those cooked up by institutions with hundreds of millions of dollars in funding and decades of experience.

“His model was the only one that seemed sane,” says Jeremy Howard, a renowned data expert and research scientist at the University of San Francisco. “The other models were shown to be nonsense time and again, and yet there was no introspection from the people publishing the forecasts or the journalists reporting on them.

Peoples’ lives were depending on these things, and Youyang was the one person actually looking at the data and doing it properly.” The forecasting model that Gu built was, in some ways, simple.

He had first considered examining the relationship among Covid tests, hospitalizations, and other factors but found that such data was being reported inconsistently by states and the federal government.

The most reliable figures appeared to be the daily death counts. “Other models used more data sources, but I decided to rely on past deaths to predict future deaths,” Gu says. “Having that as the only input helped filter the signal from the noise.”

The novel, sophisticated twist of Gu’s model came from his use of machine learning algorithms to hone his figures. After MIT, Gu spent a couple years working in the financial industry writing algorithms for high-frequency trading systems in which his forecasts had to be accurate if he wanted to keep his job.

When it came to Covid, Gu kept comparing his predictions to the eventual reported death totals and constantly tuned his machine learning software so that it would lead to ever more precise prognostications. Even though the work required the same hours as a demanding full-time job, Gu volunteered his time and lived off his savings.

He wanted his data to be seen as free of any conflicts of interest or political bias. While certainly not perfect, Gu’s model performed well from the outset. In late April he predicted the U.S. would see 80,000 deaths by May 9. The actual death toll was 79,926.

A similar late-April forecast from IHME predicted that the U.S. would not surpass 80,000 deaths through all of 2020. Gu also predicted 90,000 deaths on May 18 and 100,000 deaths on May 27, and once again got the numbers right.

Where IHME expected the virus to fade away as a result of social distancing and other policies, Gu predicted there would be a second, large wave of infections and deaths as many states reopened from lockdowns. relates to The 27-Year-Old Who Became a Covid-19 Data Superstar “Other models used more data sources, but I decided to rely on past deaths to predict future deaths,” Gu says. “Having that as the only input helped filter the signal from the noise.”

PHOTOGRAPHER: JUSTIN WEE FOR BLOOMBERG BUSINESSWEEK IHME faced some criticism in March and April, when its numbers didn’t match what was happening.

 Still, the prestigious center, based at the University of Washington and bolstered by more than $500 million in funding from the Bill & Melinda Gates Foundation, was cited on an almost daily basis during briefings by members of President Donald Trump’s Administration.

In April, U.S. infectious-disease chief Anthony Fauci told an interviewer that Covid’s death toll “looks more like 60,000 than the 100,000 to 200,000” once expected—a prediction that reflected IHME forecasts.

And on April 19, the same day Gu cautioned about a second wave, Trump pointed to IHME’s 60,000-death forecast as an indicator that the fight against the virus would soon be over. IHME officials also actively promoted their numbers.

 “You had the IHME on all these news shows trying to tell people that deaths would go to zero by July,” Gu says. “Anyone with common sense could see we would be at 1,000 to 1,500 daily deaths for a while. I thought it was very disingenuous for them to do that.” Christopher Murray, the director of IHME, says that once the organization got a better handle on the virus after April, its forecasts radically improved. But that spring, week by week, more people started to pay attention to Gu’s work.

He flagged his model to reporters on Twitter and e-mailed epidemiologists, asking them to check his numbers.

Toward the end of April, the prominent University of Washington biologist Carl Bergstrom tweeted about Gu’s model, and not long after that the U.S. Centers for Disease Control and Prevention included Gu’s numbers on its Covid forecasting website.

As the pandemic progressed, Gu, a Chinese immigrant who grew up in Illinois and California, found himself taking part in regular meetings with the CDC and teams of professional modelers and epidemiologists, as everyone tried to improve their forecasts. Traffic to Gu’s website exploded, with millions of people checking in daily to see what was happening in their states and the U.S. overall. More often than not, his predicted figures ended up hugging the line of actual death figures when they arrived a few weeks later.

With such intense interest around these forecasts, more models began to appear through the spring and summer of 2020. Nicholas Reich, an associate professor in the biostatistics and epidemiology department at the University of Massachusetts, Amherst, collected the 50 or so models and measured their accuracy over many months at the Covid-19 Forecast Hub.

“Youyang’s model was consistently among the top,” Reich says. In November, Gu decided to wind down his death forecast operation. Reich had been blending the various forecasts and found that the most accurate predictions came from the this “ensemble model,” or combined data.

“Youyang stepped back with a remarkable sense of humility,” Reich says. “He saw the other models were doing well and his work here was done.” A month before stopping the project, Gu had predicted that the U.S. would record 231,000 deaths on Nov. 1. When Nov. 1 arrived, the U.S. reported 230,995 deaths.

The IHME’s Murray has his own take on Gu’s exit. He says Gu’s model would not have picked up on the seasonal nature of the coronavirus and would have missed the winter surge in cases and deaths.

“He had the epidemic going away in the winter, and we had picked up that there was seasonality as early as May,” Murray says. The machine learning methods used by Gu work well at short-range predictions, Murray says, but “are not very good at understanding what is going on” in the bigger picture.

The algorithms, based on the past, can’t account for virus variants and how well vaccines may or may not work against them, according to Murray.

For its part, IHME called the early peak of the virus correctly, then erred when it came to predicting a steep decline in deaths until it adjusted its model to better reflect reality.

“We got it wrong the first of April,” Murray says. “Since then we are the only group that has gotten it right consistently.” Reich, who compiles the list of the major models, said that the organization’s predictions later in the pandemic were passable.

“Early on, IHME’s model didn’t do what it advertised,” Reich says. “More recently, it has been a reasonable model. I would not say it is one of the best, but it is reasonable.” Gu declined to address Murray’s remarks about his model.

Instead, he offers a data scientist’s version of a backhanded compliment. “I’m very appreciative of Dr. Chris Murray and his team for the work they did,” Gu says. “Without them, I would not be in the position I am today.”

To the extent that we can learn from this data story, Reich asks that people not rush to place too much faith in early individual models the next time a pandemic arrives. He also questions whether forecasts beyond six to eight weeks out will ever be very accurate.

 Ideally, the CDC and others will be quicker to combine models and distribute the blended data in the future. “I hope we will invest the time, energy, and money into setting up a system that is more ready to respond with a wider array of models closer to the get-go,” Reich says.

“We have to have people ready, instead of going around and knocking on peoples’ doors.” After taking a bit of a break, Gu, now 27 and living in a New York apartment, did get back into the modeling game.

This time, he’s creating figures related to how many people in the U.S. have been infected by Covid-19, how quickly vaccines are being rolled out, and when, if ever, the country might reach herd immunity.

His forecasts suggest that about 61% of the population should have some form of immunity—either from the vaccine or past infection—by June.

Before the pandemic, Gu hoped to start a new venture, possibly in sports analytics. Now he’s considering sticking to public health.

 He wants to find a job where he can have a large impact while avoiding politics, bias, and the baggage that sometimes comes with large institutions.

“There are a lot of shortcomings in the field that could be improved by people with my background,” he says. “But I still don’t know quite how I would fit in.”

Remembering Étienne Tshisekedi DRC’s Fearless Critic

Published

on

Congolese people are today remembering Étienne Tshisekedi wa Mulumba- the man who fearlessly locked horns with the country’s past leaders especially Mobutu Sese Seko and Joseph Kabila.

Étienne Tshisekedi was born on December 14, 1932 and later died on February 1, 2017 succumbing to a pulmonary embolism, in Brussels.

In 1965 When Mobutu seized power Tshisekedi was a supporter, and he served in Mobutu’s government.

However, the two clashed frequently,  and Tshisekedi was arrested and tortured between stints in the cabinet until he placed himself unambiguously in opposition with the founding of the Union for Democracy and Social Progress (UDPS).

In the early 1990s Mobutu, under international pressure, agreed to steps that were intended to lead his country, then called Zaire, to multiparty democracy. One such step was the appointment of Tshisekedi as prime minister. Tshisekedi held that post several times but in each instance for only a few months.

Tshisekedi remained a major opposition figure in 1997 when Laurent Kabila ousted Mobutu and in 2001 when Kabila was assassinated and replaced by his son, Joseph. Tshisekedi ran for president against Kabila in 2011 but lost in a process that was widely viewed as flawed. Tshisekedi and his followers did not accept the results and regarded Tshisekedi as the legitimate president.

Under the country’s 2006 constitution, Kabila’s term of office ended in December 2016, and he was not eligible for reelection.

Elections did not take place in 2016, however. Tshisekedi, who commanded a large and loyal following, was instrumental in persuading Kabila to agree to a process that would allow elections to take place in 2017.
