“Cabal Anthropology – or whether the anthropology of belief helps us understand conspiracism” [Focaal Blog]. “Let me come back to the question of “Why people believe this stuff”?…. Anyone who has argued with a conspiracy theorist, a religious zealot or political true believer of any kind knows that refutation of their evidence is fruitless. You point out contrary facts or illogical arguments and your remarks are simply cast aside as irrelevant or confirmation of the conspiracy. This is because the conspiratorial narrative is in fact an expression of belief. I decided to re-read a bunch of anthropological analyses of belief…. If we are to understand conspiratorial movements like QAnon or those following the Deep State conspiracy, we anthropologists need to promote our own insights about what belief is all about. While Needham argued that the concept of belief was useless for anthropology, we still need to explain what it means to be a believer. We need to go beyond the conventional wisdom that every conspiracy theorist suffers from some kind of cognitive deficiency, emotional damage or social isolation. The leaders and mobilizers may be emotional, committed, even fanatic (as so many leaders of social movements are), but the followers and adherents are much more like us than we’d like to admit. Resorting to a psychological explanation is not sufficient. Who among us has not suffered from anxiety, depression, loneliness or a traumatic event that might lead us to fall down the proverbial rabbit hole? Who among us has not spent hours on line immersed in some incessant search to solve a puzzle? The conspiracy followers are hardly exotic. Take away their beliefs, and they suddenly become just like us, ordinary men and women with family obligations, precarious jobs, worried about their future and their place in it. They are both strange and familiar at the same time. And it is this contrast that makes them the perfect object of anthropological scrutiny. The task of anthropology, after all, is to show that the strange is actually familiar, and that the familiar has its exotic elements. We need more cabal anthropology.” • More research needed!

acclimation - elevated global temperatures reduce the rate of photosynthesis and plant growth.


 ne of the cruelties of global warming is that high concentrations of CO2 combined with elevated global temperatures reduce the rate of photosynthesis and plant growth. These effects are called “acclimation” and “heat stress” of plants, respectively.

Acclimation is either an enhancing or inhibiting effect on photosynthesis by high CO2 concentrations. Generally, photosynthesis is enhanced as CO2 concentration is increased from a low level. Then above an elevated threshold concentration, the rate of photosynthesis saturates and can even be reduced. The mechanism of the effect is involved and has been the subject of research for many years by agricultural scientists interested in maximizing crop yields (for example in greenhouses).

 ...

Current research on plant growth under the combined effects of elevated temperature and high CO2 concentration shows that “in heat-stressed plants at normal or warmer growth temperatures, high CO2 may often decrease, or not benefit as expected, tolerance of photosynthesis to acute heat stress. Therefore, interactive effects of elevated CO2 and warmer growth temperatures on acute heat tolerance may contribute to future changes in plant productivity, distribution, and diversity.”

Virtual reality affects children differently than adults

 

Children who eat more fruit and vegetables have better mental health

Children who ate a traditional breakfast experienced better wellbeing than those who only had a snack or drink. But secondary school children who drank energy drinks for breakfast had particularly low mental wellbeing scores, even lower than for those children consuming no breakfast at all.


Children who eat a better diet, packed with fruit and vegetables, have better mental wellbeing—according to new research from the University of East Anglia.

A new study published today is the first to investigate the association between fruit and vegetable intakes, breakfast and lunch choices, and in UK school children.

It shows how eating more fruit and veg is linked with better wellbeing among secondary school pupils in particular. And children who consumed five or more portions of fruit and veg a day had the highest scores for mental wellbeing.

"While the links between nutrition and physical health are well understood, until now, not much has been known about whether nutrition plays a part in children's emotional wellbeing. So, we set out to investigate the association between dietary choices and mental wellbeing among schoolchildren."

The research team studied data from almost 9,000 children in 50 schools across Norfolk (7,570 secondary and 1,253 ) taken from the Norfolk children and Young People's Health and wellbeing Survey.

 

Children involved in the study self-reported their dietary choices and took part in age-appropriate tests of mental wellbeing that covered cheerfulness, relaxation, and having good interpersonal relationships.

Prof Welch said: "In terms of nutrition, we found that only around a quarter of secondary-school children and 28 percent of primary-school children reported eating the recommended five-a-day fruits and vegetables. And just under one in ten children were not eating any fruits or vegetables.

"More than one in five secondary school children and one in 10 primary children didn't eat breakfast. And more than one in 10 secondary school children didn't eat lunch.

The team looked at the association between nutritional factors and mental wellbeing and took into account other factors that might have an impact—such as and home situations.

Dr. Richard Hayhoe, also from UEA's Norwich Medical School, said: "We found that eating well was associated with better mental wellbeing in children. And that among secondary school children in particular, there was a really strong link between eating a nutritious diet, packed with fruit and vegetables, and having better mental wellbeing.

"We also found that the types of breakfast and lunch eaten by both primary and secondary school pupils were also significantly associated with wellbeing.

"Children who ate a traditional breakfast experienced better wellbeing than those who only had a snack or drink. But secondary school children who drank energy drinks for breakfast had particularly low mental wellbeing scores, even lower than for those children consuming no breakfast at all.

"Another interesting thing that we found was that nutrition had as much or more of an impact on wellbeing as factors such as witnessing regular arguing or violence at home.

Prof Welch said: "As a potentially modifiable factor at an individual and societal level, nutrition represents an important public health target for strategies to address childhood mental wellbeing.

"Public health strategies and school policies should be developed to ensure that good quality nutrition is available to all children both before and during in order to optimize mental wellbeing and empower to fulfill their full potential."

"Cross-sectional associations of schoolchildren's and vegetable consumption, and meal choices, with their mental : a cross-sectional study" is published in the journal BMJ Nutrition, Prevention & Health.

Pfizer booster shot (teachers)

The FDA instead limited its authorization of the third Pfizer dose to
people 65 and older,
people ages 18-64 at high risk of severe COVID-19 due to pre-existing conditions, and
individuals with frequent risk of exposure to the coronavirus through their work, such as
    health care workers and 

    teachers. 

 

“As CDC Director, it is my job to recognize where our actions can have the greatest impact. At CDC, we are tasked with analyzing complex, often imperfect data to make concrete recommendations that optimize health. In a pandemic, even with uncertainty, we must take actions that we anticipate will do the greatest good,” Walensky said in a statement.
