Hello, Stranger

Facebook, camera phones and inexpensive facial recognition software have made mass surveillance a near certainty. Huxley would be proud.

SCIENCE FICTION WRITERS have long imagined a future in which facial recognition technology makes anonymity in public obsolete.  A research study at Carnegie Mellon University suggests that this Minority Report future has already arrived, thanks to facial recognition products now commercially available, combined with the 750-million-person identity database called Facebook.

Carnegie Mellon prof Alessandro Acquisti—the real guy, with his biometric face print—worries technology may expose everyone to constant scrutiny

A CMU research team led by associate professor Alessandro Acquisti took candid photos of 93 random students on campus using a $35 webcam. Within seconds the researchers were able to determine the identities of a third of their photogenic guinea pigs, using of fthe- shelf facial recognition software from PittPatt, a software company recently acquired by Google, and publicly available profile photos from Facebook. The researchers had an even higher rate of success using the same technology to identify more than 100,000 Pittsburgh singles with otherwise pseudonymous accounts on a dating site, adding yet more complexity to the world of online dating. “We’ve been thinking about privacy in cyberspace, but we need to start thinking about it in the real world, with augmented reality,” says Acquisti. He was also able to determine the first five digits of some of the identified students’ Social Security numbers based on previous research he has done showing that those numbers are predictable if you know a person’s birth date and birthplace. That information is usually available on a person’s Face- book profile page.

It seems that Aldous Huxley was right and George Orwell was wrong. Ubiquitous surveillance isn’t being orchestrated by the governmental- Big Brother of 1984 but by advances in technology designed for convenience’s sake adopted eagerly by private citizens. Acquisti calls it the “democratization of surveillance”. And it’s coming fast. Soon after the riots broke out in London at the beginning of August, a technophile band of vigilantes formed a Google Group to discuss applying the methods pioneered by Acquisti’s research team to online photos and videos of rioters, in order to help identify looters for prosecution by law enforcement. Facial recognition tools identify a person by analyzing dozens of features, such as the length of a forehead and the distance between the eyes and the nose. Google, Facebook and Apple have already made them freely available for people to tag their friends and family in photo albums. But at what point will you have the option to snap a photo of a stranger and then pull up his or her name and whatever information the Internet offers up about them? The capability is there, but the willingness to unleash it isn’t. Yet. Google has said that its image search tool, Goggles—which uses a photo instead of text as a search term, letting you snap a photo of a painting, for example, and find out who its creator is—has the capability to find people’s identities based on a photo. But the search giant had chosen not to enable the feature because it was deemed too creepy.

When Facebook recently rolled out an internal facial recognition tool allowing friends to automatically tag other friends in photos, it inflamed some privacy advocates (whose combustion levels tend to be high around anything new that Facebook does). Those advocates seemed to overlook the fact that the very existence of Facebook’s extensive database of photos linked to people’s names creates the possibility for third parties to build a facial biometric print. While Facebook’s terms of service prohibit the scraping of information from its site, there are no technological tools in place to prevent it. And, even if there were, scraping is certainly not limited to Facebook.

“For most of us there are already identified photos of us somewhere on the Internet, and this trend will only increase,” says Acquisti. (Face.com did the doctoring on the photo on page 58.) The CMU researchers wrote a facial recognition iPhone app but decided not to release it to the public. “We developed the app to make a point,” says Acquisti. “A future in which we infer sensitive information from faces is already here, and we better start thinking whether we really want to live in that future.” Their tool, though, would be valuable only for those seeking to identify the 25,000 CMU students whose photos the researchers grabbed from Facebook. We’re still a few years away from an app that would work on a national or global scale. The two main hurdles, Acquisti says, are finding a large and reliable source of facial images (hello, DMV!) and securing enough computing power. Comparing a photo to a database of, say, 300 million photos would take many hours, whereas a functional app would need to do it in ten seconds. “If I had to guess, I would say that we are less than five years away,” says Acquisti.

Specialized facial recognition products are already on the market. BI2 Technologies has developed a $3,000 iPhone add-on called MORIS (Mobile Offender Recognition and Identification System) that dozens of police departments across the country started adopting this year. Police officers can use MORIS to take photos of suspects, and the app, using iris scans and facial recognition, will identify anyone who already has a photo in a criminal database. Microsoft and Intel have worked together to create digital billboards with face-detecting cameras that pick up on the gender and age of passersby to show them relevant ads. A startup named SceneTap installed similar cameras in bars in Chicago earlier this year, so that Windy City nightlife lovers can use their smartphones to check the crowdedness, gender ratio and average age of patrons at a given bar before deciding where to go. So far law enforcement officials are tentative about using the technology to identify people not already in criminal databases.

Though a Canadian insurance corporation graciously volunteered the use of its driver’s license photo database to Vancouver police after the devastating post-Stanley Cup hockey riot there in July, authorities declined the offer after privacy advocates expressed concerns about violation of Canadians’ civil liberties. In London, Scotland Yard is using facial recognition tools along with tips from the community to identify rioters. As good as the technology has become, it still has accuracy problems that can cause significant harm. A Massachusetts driver sued his state DMV after his license was wrongfully revoked because he looked too much like another driver, leading to ten days of administrative wrangling to get it reinstated. “We are not the beautiful and unique snowflakes we think we are.

There are many people who look likeus,” says Acquisti. More than 30 state DMVs already apply facial recognition algorithms to driver’s license photos to prevent identity fraud. If you’re worried about your privacy, now might be a good time to change your Facebook profile photo to one in which you’re wearing ridiculously oversize sunglasses.

How LinkedIn Is Looking To Help Close The Ever-Growing Skills Gap

As the job market has evolved, so too have the skills required of seekers. But when 75% of human resources professionals say a skills shortage has made recruiting particularly challenging in recent months, it would appear as though the workforce hasn’t quite kept pace. Now LinkedIn is stepping in to help close the gap.

On Tuesday, the professional social network announced the launch of a “Skills Assessments” tool, through which users can put their knowledge to the test. Those who pass are given the opportunity to display a badge that reads “passed” next to the skill on their profile pages, a validation of sorts that LinkedIn hopes will encourage skills development among its users and help better match potential employees with the right employers.

“We see an evolving labor market and much more sophistication in how recruiters and hiring managers look for skills. … We also see a changing learning market,” says Hari Srinivasan, senior director of product management at LinkedIn Learning. “The combination of those two made us excited about changing our opportunity marketplace to make the hiring side and the learning side work better together.”

So how exactly does it work? Let’s say a user wants to showcase her proficiency in Microsoft Excel. Rather than simply listing “Excel” in the skills section of her profile, she can take a multiple-choice test to demonstrate the extent to which she is an expert.

If she aces the test, not only will a badge verifying her aptitude will appear on her profile, but she will be more likely to surface in searches by recruiters, who can search for candidates by skill in the same way they might do so by college or employer. If she fails, she can take the test again, but she’ll have to wait a few months—plenty of time to develop her skillset.   

The tool has been in beta mode since March, and while just 2 million people have used it—a mere fraction of LinkedIn’s 630 million members—early results seem promising. According to LinkedIn, members who’ve completed skills assessments have been nearly 30% more likely to land jobs than their counterparts who did not take the tests.

“This has been a really good way for members to represent what they know, what they are good at,” says Emrecan Dogan, LinkedIn group product manager.

While new to LinkedIn, the practice of assessing candidates’ skills has been a standard among hiring managers for decades. But when research commissioned by LinkedIn revealed that 69% of employees feel that skills have become more important to recruiters than education, LinkedIn felt as though this was the time to give job seekers the opportunity to prove themselves from the get-go.

As important as the hard skills that members can put to the test through LinkedIn’s new tool may be, Dawn Fay, senior district president at recruiting firm Robert Half, encourages those on both side of the job search not to forget the importance of soft skills. “You wouldn’t want to rule somebody in or out just based on how they did on one particular skill assessment,” she says.

“Have another data point that you can use, question people about how they did on something and see if it’s something that can feed into the puzzle to find out if somebody is going to be a good fit.”

Why The High Number Of Employees Quitting Reveals A Strong Job Market

Published

By

While recession fears may be looming in the minds of some, new data from the Bureau of Labor Statistics shows that the economy and job market may actually be strengthening.

The quits rate—or the percentage of all employees who quit during a given month—rose to 2.4% in July, according to the BLS’s Jobs Openings and Labor Turnover report, released Tuesday. That translates to 3.6 million people who voluntarily left their jobs in July.

This is the highest the quits rate has been since April 2001, just five months after the Labor Department began tracking it. According to Nick Bunker, an economist at the Indeed Hiring Lab, the quits rate tends to be a reflection of the state of the economy.

“The level of the quits rate really is a sign of how strong the labor market is,” he says. “If you look at the quits rate over time, it really drops quite a bit when the labor market gets weak. During the recession it was quite low, and now it’s picked up.”

The monthly jobs report, released last week, revealed that the economy gained 130,000 jobs in August, which is 20,000 less than expected, and just a few weeks earlier, the BLS issued a correction stating that it had overestimated by 501,000 how many jobs had been added to the market in 2018 and the first quarter of 2019. Yet despite all that, employees still seem to have confidence in the job market.Today In: Leadership

The quits level, according to the BLS, increased in the private sector by 127,000 for July but was little changed in government. Healthcare and social assistance saw an uptick in departures to the tune of 54,000 workers, while the federal government saw a rise of 3,000.

The July quits rate in construction was 2.4%, while the number in trade, professional and business services, and leisure and hospitality were 2.6%, 3.1% and 4.8%, respectively. Bunker of Indeed says that the industries that tend to see the highest rate of departuresare those where pay is relatively low, such as leisure and hospitality. An unknown is whether employees are quitting these jobs to go to a new industry or whether they’re leaving for another job in the same industry. Either could be the case, says Bunker.

In a recently published article on the industries seeing the most worker departures, Bunker attributes the uptick to two factors—the strong labor market and faster wage growth in the industries concerned: “A stronger labor market means employers must fill more openings from the ranks of the already employed, who have to quit their jobs, instead of hiring jobless workers. Similarly, faster wage growth in an industry signals workers that opportunities abound and they might get higher pay by taking a new job.”

Even so, recession fears still dominate headlines. According to Bunker, the data shows that when a recession hits, employers pull back on hiring and workers don’t have the opportunity to find new jobs. Thus, workers feel less confident and are less likely to quit.

“As the labor market gets stronger, there’s more opportunities for workers who already have jobs. So they quit to go to new jobs or they quit in the hopes of getting new jobs again,” Bunker says. He also notes that recession fears may have little to do with the job market, instead stemming from what is happening in the financial markets, international relations or Washington, D.C.

So what does the BLS report say about the job market? “Taking this report as a whole, it’s indicating that the labor market is still quite strong, but then we lost momentum,” Bunker says. While workers are quitting their jobs, he says that employers are pulling back on the pace at which they’re adding jobs. “While things are quite good right now and workers are taking advantage of that,” he notes, “those opportunities moving forward might be fewer and fewer if the trend keeps up.”

No Seat At The Global Table For Indigenous African Cuisine

Published

on

Gastronomic tourism based on African food could easily increase and create new value chains that unlock billions in untapped wealth for the continent, but what is stopping us?


Food and tourism are an integral part of most economies, globally. Food is undeniably a core part of all cultures and an increasingly important attraction for tourists. To satisfy their wanderlust, contemporary tourists require an array of experiences that include elements of education, entertainment, picturesque scenery and culinary wonders.  The link between food and tourism allows destinations to develop local economies; and food experiences help to brand and market them, as well as supporting the local culture and knowledge systems.

 This is particularly important for rural communities, where 61% of sub-Saharan Africans live, according to the World Bank last year. These communities have often felt the brunt of urbanization, which has resulted in a shift away from rural economies. If implemented effectively, Africa could get a piece of the gastronomic tourism pie, which was worth $8.8 trillion last year, according to the World Travel & Tourism Council.

However, there is currently very little public information to pique the interest of tourists about African food. World-renowned South African chef Nompumelelo Mqwebu sought to remedy this with her self-published cookbook, Through the Eyes Of An African Chef.

“I think where it was very clear to me that I needed to do something was when I went to cooking school. I trained at Christina Martin School of Food and Wine. I thought I was actually going to get training on South African food and, somehow, I assumed we were talking indigenous food.

 “I was shocked that we went through the whole year’s curriculum and we didn’t cover anything that I ate at home; we didn’t cover anything that my first cousins, who are Sotho, ate in Nelspruit (in South Africa’s Mpumalanga Province); we didn’t cover anything that would come from eSwatini, which is where my mother is from,” Mqwebu says.

By self-publishing, she has ultimately contributed to a value chain that has linked local food producers and suppliers, which includes agriculture, food production, country branding and cultural and creative industries.

“I am a member of Proudly South African, not only my business, but the book as well. Part of the reason is that the cookbook was 100% published in South Africa. So, everybody who worked on the cookbook, and printing, was all in South Africa, which is something quite rare these days because authors have their books published abroad.”

The Proudly South African campaign is a South African ‘buy local’ initiative that sells her cookbook on their online platform as its production adheres to the initiative’s campaign standards. Self-publishing has allowed Mqwebu to promote her book for two years and to directly communicate with her audience in a way she thought was best, while exposing her to a vast community of local networks. She recalls her first step towards creating her own body of work.

“I was in culinary school when I wrote the recipe for amadumbe (potato of the tropics) gnocchi. We were making gnocchi and I thought, ‘so why aren’t we using amadumbe because it’s a starch?’ and when I tasted it, I thought, ‘this could definitely work’. I started doing my recipes then.

 “And there was talk about, ‘we don’t have desserts as Africans’. I did some research and found we ate berries, we were never big on sugar to begin with. That’s why I took the same isidudu (soft porridge made from ground corn) with pumpkin that my grandmother used to make and that became my dessert. “I also found that when I went to libraries looking for indigenous recipes, I couldn’t really find something that spoke to me as a chef. I found content that looked like history books. It was not appealing. It was not something, as a chef, I could proudly present to another chef from a different part of the world, so I knew I had to write my book,” Mqwebu says about the award-winning recipe book that chronicles African cuisine.

Financial and health benefits

According to the World Travel & Tourism Council, in 2018, the tourism sector “contributed 319 million jobs, representing one in 10 of all jobs globally and is responsible for one in five of all new jobs created in the world over the last five years. It has increased its share of leisure spending to 78.5%, meaning 21.5% of spending was on business.”

To narrow in on how lucrative food can be, the World Food Travel Association estimates that visitors spend approximately 25% of their travel budget on food and beverages. The figure can get as high as 35% in expensive destinations, and as low as 15% in more affordable destinations. “Confirmed food lovers also spend a bit more than the average of 25% spent by travelers in general.”

However, there is a widely-held view that the African continent is not doing enough to maximize its potential to also position itself as a gastronomic tourism destination, using its unique edge of indigenous knowledge systems (IKS).

“We are not a culinary destination and we will never be while we are still offering pasta as the attraction for our tourists,” Mqwebu says.

Dr George Sedupane, who is the Coordinator of the Bachelor of the Indigenous Knowledge Systems program in South Africa’s North-West University, echoes Mqwebu’s sentiments.

“I often cringe when I go to conferences and there are guests from all over the world and we serve them pasta. Why would they come from Brazil to eat pasta here? They can have pasta in Italy. Why don’t we serve them umngqusho (samp and beans)?

“We need to be creating those experiences around our culture. We are failing to capitalize on our strengths. There is a lack of drive to celebrate what we have,” says Sedupane, who also teaches modules and supervises research in indigenous health and nutrition.

Writer and historian Sibusiso Mnyanda says current innovations in African food technology are born out of necessity, rather tourism and cultural ambitions.

“Food security is becoming an issue that is leading to IKS around farming being prioritized. In Nigeria, they are innovating dry season farming, because of deforestation and soil being de-cultivated. 

“So those indigenous knowledge strategies are being used in countries where it is a necessity and where there are enough advances related to the fourth industrial revolution. The traditional ways of producing food are not only much more organic, they are also crop-efficient,” Mnyanda says.

Nigeria may have inadvertently innovated a health solution related to colon cancer through its diet. Sedupane tells FORBES AFRICA an anecdote.

“There was a study where the colons of an African country that did not consume a lot of meat was compared to Europeans. The Africans had a much better profile as a result and there are people who want to buy African stool to get that kind of rich bacteria, that you get on an African plant-based diet.”

The study Sedupane is referring to was conducted in Nigeria and it states that: “Nigeria showed the average annual incidence of colorectal cancer was 27 patients per year. This shows that even if it seems that incidence rates are increasing in Nigeria, such rates are still about one-tenth of what is seen in the truly developed countries.”

In a bid to find reasons for this rarity of colon and rectal cancer, the study concluded that, among other reasons, the protective effects of Nigeria’s starch-based, vegetable-based, fruit-based, and spicy, peppery diet, and geographical location which ensures sunshine all year round, played a role in the country’s colon health.

Interestingly, it seems the potential value of African food could not only be based on what goes in but what also comes out as healthy faecal matter is big business globally. In 2015, The Washington Post published that one could potentially earn $13,000 a year selling their poop. 

The American-based company OpenBiome has been processing and shipping frozen stool to patients who are very sick with infections of a bacteria called C.difficile. It causes diarrhea and inflammation of the colon, leaving some sufferers house-bound. “Antibiotics often help, but sometimes, the bacteria rears back as soon as treatment stops. By introducing healthy faecal matter into the gut of a patient (by way of endoscopy, nasal tubes, or swallowed capsules), doctors can abolish C. difficile for good… And yes, they pay for healthy poop: $40 a sample, with a $50 bonus if you come in five days a week. That’s $250 for a week of donations, or $13,000 a year,” the publication stated.

Sedupane is of the view that a diet which includes indigenous foods could vastly improve one’s quality of life.

He says small changes could be made, such as including more of indigenous greens, namely sorghum and millet, to breakfast. The grains are gluten-free and produce alkaline which boosts the pH level of fluids in the body and reduces acidity.

“Moving to our legumes, we have indlubu (Bambara groundnut) which is very rich and helps in the secretion of serotonin in the brain. This so important nowadays with the increase of depression. It’s easy to digest, and is great for cholesterol and moderating blood sugar,” Sedupane says.

 Mnyanda is also of the view that food is imperative to health and medicinal properties. He says traditional healers primarily use natural herbs in their practice. “These are used in pain relief and healing. Things like cannabis, camphor, African potatao and red carrots. So, food is not just used for nutritional purposes.”

Other African superfoods include, Baobab fruit, Hibiscus, Tamarind, Kenkiliba, Amaranth, Moringa and pumpkin leaves. 

Cultural and historical benefits

Gastronomic tourism also includes the promotion of heritage sites that are known to revolve around dishes that are of historic importance. They enhance the travel experience, they encourage the acquisition of knowledge and a cultural exchange.

There is a unanimous view that vast amounts of knowledge have been lost to history and there is a huge knowledge gap in African societies as a result of colonization and urbanization.

“Part of the colonial agenda was to make sure food security did not belong to indigenous groups. Therefore, archiving of these knowledge systems was not a priority. Especially during industrialization, where people moved from their villages to the city you found that the knowledge got left behind,” Mnyanda says.

He offers a contemporary example of how modernization continues to push African practices to the fringes: “To this day, abathwa (the San people) hunt their meat, but you find that because of changing agricultural practices and land reform on the Kruger National Park, they are being forced to move into the cities and industrial areas, therefore they are no longer able to practice their culture of hunting. As a result, their diet is changing.” Sedupane shares the view that the fundamentals of farming and astrology have also been exiled from public knowledge.

“The fundamentals of IKS were based on the understanding of the laws of nature – how and when things were done. Harvest cycles were linked with understanding astrology. They would not harvest until certain stars were visible in the sky. There was a dependence on nature.

“With industrialization, rather than working with nature, humans are seen as being above, as controlling, as directing it. The natural cycle is often tempered with rather than trying to work with it.”

Not all is lost however. There are historical practices that have stood the test of time and continue to be a part the few foods that are internationally associated with South Africa. Mqwebu says that, “historically, we ate more plants than meat because our ancestors had to hunt and the game back then was not tame. So, there were no guarantees that you would return with meat. And that’s where things like umqwayiba (biltong) come from. They had to preserve the meat, because wasting was not part of the culture”.

According to a 2015 exploratory research project conducted under the guidance of research institute Tourism Research in Economic Environs and Society director Professor Melville Saayman, biltong contributes more than R2.5 billion ($163 million) to the South African economy.

Perhaps, like the faecal transporting company, Africa will soon realize the ‘wasted’ opportunity and that there is loads of money to be made in gastronomic tourism for all its inhabitants, whether they are rural or urban, technological or indigenous.
