"As a #quantitative #socialscientist who has studied #religious change in modern societies for more than 25 years, I’m surprised – and sceptical. I do not doubt that the #BibleSociety acted in good faith, but they haven’t engaged with the mountain of #evidence, some of it very recent, pointing to #religiousdecline.

"Modern civilisation has a number of extremely delicate and highly interconnected components whose graceful degradation is effectively impossible."

It is "much easier to break things than to build them up. The government administrations of Britain, France and Germany for example, were set up at a time in the nineteenth century when the rising middle classes demanded a properly functioning state[…]. It took perhaps a generation for professional, neutral public services to fully emerge."

"Forty years of globalised neoliberalism have broken our societies, our economies and our political systems, and we no longer have the ability to put them back together."

The piranha problem: Large effects swimming in a small pond.

In a lot of social science research, small, random factors are reported as having large effects on social and political attitudes and behavior (social priming, hormonal levels,parental socioeconomic status, weather, ...). Studies have claimed to find large effects from these and other inputs.

The results show that it would be extremely unlikely to have all these large effects coexisting—they would have to almost exactly cancel each other out.

arXiv.orgThe piranha problem: Large effects swimming in a small pondIn some scientific fields, it is common to have certain variables of interest that are of particular importance and for which there are many studies indicating a relationship with different explanatory variables. In such cases, particularly those where no relationships are known among the explanatory variables, it is worth asking under what conditions it is possible for all such claimed effects to exist simultaneously. This paper addresses this question by reviewing some theorems from multivariate analysis showing that, unless the explanatory variables also have sizable dependencies with each other, it is impossible to have many such large effects. We discuss implications for the replication crisis in social science.

I tagged research data over multiple years.

There was an unintended outcome of tagging ALL observations from every Agile sprint—rather than only tagging observations that related to the current sprint's research focus…

As time passed, some of the qualitative data became quantitative as the sample size grew.

The world's first #quantitative measurement at this scale of gas flows and their structures of a nearby supermassive black hole in all phase gases, including #plasma, #atomic, and #molecular. Such high resolution allowed the team to team to capture the accretion flow heading towards the supermassive black hole

Julie #Billaud: Administrative techniques devised to engage parties to a conflict "are changing as a result of external sources of pressure for ‘evidence-based programming’, turning personalised case-based monitoring into a new form of ‘audit culture’ based on statistical evidence. Paradoxically, relying on numbers to realise the utopia of ‘humanising war’ makes the very ‘humans’ who are supposed to benefit from it disappear from view."

An #introduction:

I specialize in #quantitative #imageAnalysis, mostly applied to #microscopy, and mostly in #biomedical applications.

I’ve been doing this for 25+ years. I used to have a tenured university position, and moved to industry about 7 years ago. Industry is just like academia, but with fewer students, fewer grants, and more secrecy.

Check out diplib.org

I love good #music, good #food, and building models (shoutout to #Lego, #MetalEarth and #UGears).

#introduction and my first own 🦣 #toot:

I'm a social scientist interested in #attitudes toward #immigration & #refugees, effects of #media and #PolComm, using #quantitative, #TextAsData & #computational methods. For more check: czymara.com/research

Currently, I am a #postoc at U #TelAviv & GoetheU #Frankfurt.

I'm mostly here to check new #research and recent developments in #academia, but also up for cheeky memes and bad puns.

#introduction
Hi, I am a #quantitative #ecologist. I plan to use :mastodon: to keep track of cool research, stumble upon new #biology or #math, and every now and then find obscure modelling references from the 80s. I care about doing my analyses slow, reproducible research and fair publishing.

I am especially interested in #bioticinteractions, #demography, and the interplay between them. And increasingly in #stats techniques to infer robust #biodiversity trends.

#introduction I'm a Post-doc working on mathematical and statistical model of malaria and COVID-19. I was actually trained as field marine ecologist, and only started picking up on my quantitative skills during my PhD in 2016, in which I drifted towards #infectious disease. Nevertheless, I love both #epidemiology and #ecology word, and hope to contribute to both domains using my #computational and #quantitative skills. I am #rstats enthusiast, but also speak #python and #cpp if I have to 😅
