Yi-Fu Tuan, who died in Madison, Wis. on Aug. 10, 2022, was known as the most influential academic you never knew. Referred to as the father of humanistic geography, his most influential works dealt with the concepts of space, place and sense of place.

As we enter Geography Awareness Week, it’s important to recognize Tuan’s lasting impact on the field of geography.

Born in the Chinese city of Tianjin in 1930, his academic career took him around the globe, eventually leading him to the University of Wisconsin–Madison in 1983 where he attained emeritus status in 1998. Tuan received several awards including the prestigious Vautrin Lud Prize in 2012.

In his work, Tuan deals with spaces as general, objective areas, whereas places have meaning and memories. A sense of place is a deep emotional attachment to a place. In a world dealing with the challenges of the pandemic, refugee crises, political unrest and the impacts of climate change, his work is just as relevant as ever.

Landscapes of Fear

Tuan’s 1979 book, Landscapes of Fear, is intensely pertinent for our current pandemic reality. It’s an exploration into spaces of fear and how these landscapes evolve during our lives and vary over time. Tuan talked of the human response to disease as being a combination of common sense and fear. He speaks about many past responses to disease being reasonable, but also often going beyond the bounds of reason.

COVID-19 lockdowns and restrictions may have seemed acceptable but frequently created a terror of their own. Families desperate to see their older loved ones in long-term care facilities were unable to visit in their final days of life. Closed businesses and empty streets became a source of anxiety as many wondered if, once opened, these spaces would be safe to visit.

There was concern over whether travel was safe. Media was replete with a discourse of fear that led many to question whether it was a good idea to travel.

But that reduction in visitors to certain spaces created renewed appreciation for the places near our own homes. As restrictions eased, these landscapes were no longer feared. Our love of place overtook our desire for protection.

Transforming cityscapes

Tuan’s analysis in the chapter Fear in the City is also timely. Recent attacks like those in Saskatchewan, London, Ont. and Norway leave us anxious about streetscapes.

Tuan’s apt analysis showed us how those that govern cities focus more on economic and commercial activities, rather than social needs. And how the city itself can become a disorienting space. A labyrinth of disorder and social strife especially among those of different classes, races and ethnicities.

This disorder and social strife manifested itself visibly in the killings of George Floyd, Breonna Taylor and Ahmaud Arbery fostering greater mistrust in urban public spaces.

To offset these landscapes of fear, a counter-narrative emerged, transforming streets into spaces of sympathy for vigils, protests and marches.

That transformation is also apparent in the ongoing protests in Iran. The fight for freedom in public spaces has seen Iranian women leading protests against overbearing government control and many supporting these rights in public spaces around the world.

Place is security

Tuan’s concept of place became all the more significant during lockdown. The sanctuary of our most important shelter, the home, was challenged by the threat of an invisible virus.

But home as a secure place is a privilege not all have. As COVID-19 spread, hundreds fled homeless shelters, for fear of contracting the virus. Our most vulnerable citizens, including those experiencing homelessness, lacked security in place. Government action was needed, that for the time being, included sanctioned encampment sites.

Yi-Fu Tuan speaking at the University of California Santa Barbara in 2011.

Recent surges in Canada’s immigration highlight how migrants too need safe spaces to develop a sense of place.

As a geographer, I have studied how people establish a sense of place through multicultural festivals, ‘sensuous geographies’ and shared place identity. These intimate connections of place and belonging contribute to a sense of community. But when so many events were cancelled throughout the pandemic it had a drastic impact on communities, affecting our sense of place, shared memories and emotional geographies.

Because of their loss of place and space, migrants especially need help to connect to places. We could better assist them by understanding Tuan’s idea of topophilia — an intense sense of place based on social constructions and cultural identities.

Tuan said that we all have a deep need to connect through our senses. The pandemic has highlighted our deep need to connect physically rather than virtually. We have yet to truly understand its impact on our sense of place. With so many other sites closed, streets were re-imagined as places for dwelling, playing and connecting rather than merely spaces of transport and mobility.

Space is freedom

Space and Place is one of Tuan’s most highly referenced books. It’s a study about how people form emotional connections and attachments to their home, neighbourhood and nations, and how feelings about space and place are affected by time. What begins as undifferentiated space becomes place over time as we get to know it better and assign it value. A sense of place brings us security and safety, and we desire the need for openness and freedom in our space.

The so-called freedom convoy in downtown Ottawa highlighted Tuan’s notion of space being about freedom. While the encampment provided freedom to those who took part, it also took freedom away from residents whose everyday lives were suddenly restricted.

It took the safety and security away from residents who have a meaningful and deep sense of place there. The convoy raised questions about our democratic rights — whose freedoms were really being protected, whose were being denied and the controversy over security and policing in public places.

We could all learn from Tuan’s thinking. We must become humanistic caregivers of each other and the planet and avoid protectionist measures that perpetuate fear. Tuan was more concerned about what connected us, not what drove wedges between us. The intimate connection between space and place is highly nuanced. “We are attached to one, and long for the other.”

In these challenging times, we should all remember Yi-Fu Tuan and what makes us human first: the need for security in place and freedom in space.

Infant formula shortages forced some parents to feed their babies in less healthy ways

Many families in the US encountered empty shelves when they went in search of infant formula during COVID-19.

The Research Brief is a short take about interesting academic work.

The big idea

One third of families who relied on formula to feed their babies during the COVID-19 pandemic were forced by severe infant formula shortages to resort to suboptimal feeding practices that can harm infant health, according to our research published in the journal Maternal and Child Nutrition.

Infant formula shortages left 70% of U.S. store shelves bare in May 2022, with 10 states reporting out-of-stock rates of 90% or greater.

As psychology researchers who study breastfeeding, this situation left us concerned for the safety of infant nutrition. With two colleagues who focus on public health, we conducted an online survey of over 300 infant caregivers in the U.S. to understand how many families had trouble obtaining infant formula and what they fed their babies when they did.

Considering the scope of the formula shortages, we were not surprised that 31% of the formula-feeding families we surveyed reported challenges obtaining infant formula, the most common being that it was sold out and they had to travel to more than one store.

But their babies still needed to eat. Being unable to get their hands on infant formula pushed caregivers to potentially unhealthy or even dangerous stopgaps. For example, 11% of the formula-feeding families surveyed said they practiced “formula-stretching” – diluting infant formula with extra water to make formula supplies last longer, which provides a baby with less nutrition in each bottle.

Furthermore, 10% of formula-feeding families reported substituting cereal for infant formula in bottles, 8% prepared smaller bottles and 6% skipped formula feedings for their infants, which all provide infants with less nutritious meals.

Exclusively breastfeeding families were insulated against these supply disruptions. Almost half of breastfeeding families surveyed reported that COVID-19 lockdowns actually allowed them time to increase their milk supply.

Why it matters

Our study suggests that the waves of formula shortages from 2020 to 2022 in the U.S. were more than just an inconvenience for parents. Instead, this study is the first to document that formula shortages likely had real and widespread adverse impacts on infant nutrition, given that a large proportion of parents surveyed resorted to feeding their baby in ways that can harm infant health.

For instance, studies have shown that adding extra water to “stretch” formula can result in infant malnutrition, growth and cognitive delays and even seizures and death in extreme cases. Adding cereal to bottles increases the risk of choking-related deaths and severe constipation. Moreover, feeding infants age-inappropriate foods can have lifelong consequences for cognitive development and growth, leading to a higher risk for chronic illnesses like obesity and cardiovascular disease.

Given that approximately 75% of infants in the U.S. are fed with infant formula in the first six months of life, formula shortages could put roughly 2.7 million babies each year at risk for suboptimal feeding practices.

What’s next

A perfect storm of formula recalls, ingredient shortages and shipping delays contributed to COVID-19-related formula shortages in the U.S. Although President Joe Biden’s administration has taken some steps to improve distribution infrastructure, the U.S. does not currently have infant nutrition disaster plans in place beyond common-sense recommendations for individuals.

Unfortunately, climate change will likely increase the risk of formula-supply disruptions over the next century because of the increased frequency of natural disasters.

The best way to protect infant nutrition from supply chain issues is to promote and support breastfeeding, which provides optimal infant nutrition and insulates infants from those disruptions. Since not all babies can be breastfed, though, governmental policies could help prevent and address acute formula shortages and ensure equitable formula access for all.

Physical exercise practiced by patients submitted to bariatric surgery acts on brain regions involved in food intake, reducing hunger or accelerating satiety, for example. This was the result observed in a clinical trial conducted at Hospital das Clínicas (HC), the hospital complex run by the University of São Paulo’s Medical School (FM-USP) in Brazil. An article on the study, pointing to positive effects of exercise on obesity-related conditions in post-bariatric patients, is published in the International Journal of Obesity.

Physical exercise practiced by patients submitted to bariatric surgery acts on brain regions involved in food intake, reducing hunger or accelerating satiety, for example. This was the result observed in a clinical trial conducted at Hospital das Clínicas (HC), the hospital complex run by the University of São Paulo’s Medical School (FM-USP) in Brazil. An article on the study, pointing to positive effects of exercise on obesity-related conditions in post-bariatric patients, is published in the International Journal of Obesity.

The study showed that an exercise training program starting three months after bariatric surgery produced functional alterations in brain networks associated with food intake and modified by obesity. The findings confirm the hypothesis that exercise and bariatric surgery act synergistically on the connectivity among brain regions associated with cognition, reward and emotional regulation, potentially moderating hunger and enhancing satiety.

According to the article, exercise increased the connectivity between the hypothalamus (the brain region that controls homeostasis, including regulation of appetite and energy expenditure) and the brain’s sensory areas. At the same time, it apparently decreased the link between the default mode network, which is more active during a resting state, and the salience network, the brain region involved in decision-making.

The researchers also found that exercise after bariatric surgery appeared to modulate the medial hypothalamic nucleus involved in appetite suppression and increased energy expenditure.

“The regulation of energy expenditure is governed by multiple internal and external signals. People with obesity display major dysregulation of brain regions associated with appetite and satiety. Our study showed that exercise by post-bariatric patients helped ‘normalize’ these complex networks so as to improve the central control of food intake. For example, some of these regions are activated and connect more intensely in people with obesity when they eat fatty or sugary food, increasing their desire to consume such food. We found that exercise counteracts this effect, at least in part,” Bruno Gualano, last author of the article, told Agência FAPESP. Gualano is a professor at FM-USP.

The study was supported by FAPESP via a research grant for the project “Effects of exercise training in patients undergoing bariatric surgery: a randomized clinical trial” and was part of the PhD research of Carlos Merege Filho, first author of the article, with a scholarship from FAPESP. The co-authors included Hamilton Roschel, Marco Aurélio Santo, Sônia Brucki, Claudia da Costa Leite, Maria Concepción García Otaduy and Mariana Nucci (all of whom are affiliated with HC-FM-USP); and John Kirwan of Pennington Biomedical Center (USA).

Considered one of the world’s main public health problems, obesity is a chronic disease characterized by excessive body fat accumulation and a major risk factor for cardiovascular and musculoskeletal disorders, as well as severe COVID-19. The parameter used for diagnosis in adults is body mass index (BMI), defined as weight in kilograms divided by height squared in meters. A BMI between 25 and 29.9 indicates overweight, while 30 or more signals obesity, according to the World Health Organization (WHO).

Brazil has one of the highest rates of overweight and obesity in the world. According to projections, almost 30% of the adult population will be obese in 2030. A billion people, or 17.5% of the world’s adult population, will be obese by then, according to the World Obesity Atlas 2022 published by the World Obesity Federation.

Importance

From the clinical standpoint, Gualano believes, the findings suggest that exercise should be considered an important complementary therapy to improve brain functions and enhance the known benefits of bariatric surgery, such as a reduction in cardiometabolic risk factors, as well as preservation of muscle mass and bone health.

He and his group have been conducting research in this field since 2018, as evidenced by other publications, one of which showed that exercise attenuated and reversed loss of muscle mass, improving muscle strength and function in post-bariatric patients. Genotypic and phenotypic analysis evidenced metabolic and structural remodeling of skeletal muscle.

In another study, exercise reduced risk factors for diseases associated with obesity, such as diabetes, high blood pressure and atherosclerosis (hardening of the arteries), by increasing sensitivity to insulin, combating inflammation and improving the health of blood vessels.

Methods

The randomized clinical trial reported in the International Journal of Obesity involved 30 women aged between 18 and 60 who had been submitted at HC-FM-USP’s bariatric surgery unit to a Roux-en-Y gastric bypass, which creates a small stomach pouch to restrict food intake and bypasses a large portion of the small intestine to limit calorie absorption. A majority of patients admitted to the unit are women. 

Half the study sample were randomly assigned to a six-month exercise program of resistance and aerobic training three times a week, starting three months after the operation and supervised by a team of physical education professionals.

Clinical, laboratory and brain functional connectivity parameters were assessed at the start of the trial, as a baseline, and again three and nine months after the operation. Functional magnetic resonance imaging (fMRI) was used to detect connectivity between anatomically distinct brain areas organized as networks, and to analyze the combined effects of the surgical procedure and exercise training. Data collection began in June 2018 and ended in August 2021.

“The literature has already shown that post-bariatric patients have many brain alterations compatible with improved control of appetite, satiety and hunger in neural circuits that govern food intake. Our study found that exercise training bolstered this response,” Gualano said, noting the importance of lifestyle changes to maintain the benefits of weight loss for people with obesity.

Bariatric surgery can currently be performed on patients with a BMI of between 30 and 35 and type 2 diabetes that has not been controlled for more than two years, and patients with a BMI over 35 who have other diseases associated with overweight, such as high blood pressure, sleep apnea or hepatic steatosis (fatty liver disease). For people with comorbidities, the recommended BMI is over 40.

In the past five years, 311,850 bariatric surgeries have been performed in Brazil; 14.1% were paid for by the SUS (Sistema Único de Saúde), the national health service. The rest were covered by insurance policies or paid for privately, according to the Brazilian Bariatric and Metabolic Surgery Society (SBCBM).

“Regular exercise is known to induce several physiological adaptations that translate into health benefits. These benefits are reversed if the patient stops exercising regularly. Our study didn’t measure the duration of the brain changes induced by exercise, however. They’re highly likely to diminish and possibly even go into reverse as the amount and intensity of exercise decrease. It’s crucial to adopt a healthy lifestyle in order for the responses to bariatric surgery to be long-lasting,” Gualano said.

Next steps for the research group will include studying the effects in people with obesity of exercise and diet combined with other weight loss strategies, including new drugs such as peptide analogs or incretin mimetics, a class of medications commonly used to treat type 2 diabetes. Incretins are gut hormones that aid digestion and blood sugar control by signaling to the brain to stop eating after a meal.

In early January, the National Health Surveillance Agency (ANVISA) approved semaglutide as an anti-obesity drug for long-term weight management. The drug had previously been approved only for patients with type 2 diabetes. It is the first injectable anti-obesity medication available in Brazil and is supposed to be administered once a week. It is said to enhance satiety, modulate appetite and control blood sugar.

"We Are Headed For Another Train Wreck": Bill Ackman Blames Janet Yellen For Restarting The Bank Run

Yesterday morning we joked that every time Janet Yellen opens her mouth, stocks dump.

Well, it wasn't a joke, and as we repeatedly noted today, while Jerome Powell was busting his ass to prevent a violent market reaction - in either direction - to his "most important Fed decision and presser of 2023", the Treasury Secretary, with all the grace of a senile 76-year-old elephant in a China market, uttered the phrase...

  • YELLEN: NOT CONSIDERING BROAD INCREASE IN DEPOSIT INSURANCE

... and the rest was silence... or rather selling.

Commenting on our chart, Bloomberg's Mark Cudmore noted it was Yellen who was "to blame for the stock slump", pointing out that "the pessimistic turn in US stocks began within a minute of Janet Yellen starting to speak."

The S&P 500 rose almost 1% in the first 47 minutes after the Fed decision. Powell wasn’t the problem either: the index was 0.6% higher in the first 17 minutes after his press conference started.

Why am I picking that exact timing of 2:47pm NY time? Because that is the minute Yellen started speaking at the Senate panel hearing. The high for the S&P 500 was 2:48pm NY time and it fell more than 2.5% over the subsequent 72 minutes. Good effort.

Picking up on this, Bloomberg's Mark Cranfield writes that banking stocks globally are set to underperform for longer after Janet Yellen pushed back against giving deposit insurance without working with lawmakers. He adds that "to an aggressive trader this sounds like an invitation to keep shorting bank stocks -- at least until the tone changes into broader support and is less focused on specific bank situations." Earlier, we addressed that too:

Looking ahead, Cranfield warns that US financials are likely to be the most vulnerable as they are the epicenter of the debate. Although European or Asian banking names may outperform US peers, that won’t be much consolation for investors as most financial sector indexes may be on a downward path.

The KBW bank index has tumbled from its highs seen in early February, but still has a way to go before it reaches the pandemic-nadir in 2020. Traders smell an opening for a big trade and that will fuel more downside. Probably until Yellen blinks.

And if Bill Ackman is right, she will be doing a whole lot of blinking in days if not hours.

Ackman crying in public

While we generally make fun of Ackman's self-serving hot takes on twitter, today he was right when he accused Yellen of effectively restarting the small bank depositor run which according to JPMorgan has already seen $1.1 trillion in assets withdrawn from "vulnerable" banks. This is what Ackman tweeted:

Yesterday, @SecYellen  made reassuring comments that led the market and depositors to believe that all deposits were now implicitly guaranteed. That coupled with a leak suggesting that @USTreasury, @FDICgov and @SecYellen  were looking for a way to guarantee all deposits reassured the banking sector and depositors.

This afternoon, @SecYellen walked back yesterday’s implicit support for small banks and depositors, while making it explicit that systemwide deposit guarantees were not being considered.

We have gone from implicit support for depositors to @SecYellen explicit statement today that no guarantee is being considered with rates now being raised to 5%. 5% is a threshold that makes bank deposits that much less attractive. I would be surprised if deposit outflows don’t accelerate effective immediately.

Ackman concluded by repeating his ask: a comprehensive deposit guarantee on America's $18 trillion in assets...

A temporary systemwide deposit guarantee is needed to stop the bleeding. The longer the uncertainty continues, the more permanent the damage is to the smaller banks, and the more difficult it will be to bring their customers back.

... but as we noted previously pointing out, you know, the math...

... absent bipartisan Congressional intervention - which is very much unlikely until the bank crisis gets much, much worse - this won't happen and instead the Fed will continue putting out bank fire after bank fire - even as it keeps hiking to overcompensate for its "transitory inflation" idiocy from 2021, until the entire system burns down, something which Ackman's follow-up tweet was also right about:

Consider recent events impact on the long-term cost of equity capital for non-systemically important banks where you can wake up one day as a shareholder or bondholder and your investment instantly goes to zero. When combined with the higher cost of debt and deposits due to rising rates, consider what the impact will be on lending rates and our economy.

The longer this banking crisis is allowed to continue, the greater the damage to smaller banks and their ability to access low-cost capital.

Trust and confidence are earned over many years, but can be wiped out in a few days. I fear we are heading for another a train wreck. Hopefully, our regulators will get this right.

Narrator: no, they won't.
