Anthony Heath and Yaojun Li provide "a fascinating account of how sociologists [...] have succeeded in developing and testing theories about the causes, trends, and consequences of social mobility."

Blooming in Blue

Summers in the Barents Sea — a shallow region off the northern coasts of Norway and Russia — trigger phytoplankton blooms like the one in this satellite image. The blue shade of the bloom suggests the work of coccolithophores, a type of plankton armored in white calcium carbonate. This type of plankton thrives in the warm, stratified waters of the late summer. Earlier in the year, the water tends to be nutrient-rich and well-mixed, conditions which favor diatom plankton species instead. Their blooms appear greener in satellite images. (Image credit: W.

We need a conceptual framework for LLMs and social visibility

As a literary executor I promised to maximise diffusion of my mentor’s work to extent I could without damaging its integrity. Now receiving requests from publisher to license training on the books. This certainly aids diffusion by increasing visibility within the model but does it damage integrity? We still lack a conceptual framework for thinking about how existing hierarchies of attention will be restructured by visibility or its absence within a model. I find it easy to see how the implications could be complex and multifaceted, in ways we urgently need to understand for higher education.

For example my blog now gets lots of traffic via Perplexity & ChatGPT because it’s clearly identified as a high authority source. ChatGPT can answer questions about me with sufficient detail that I suspect it was trained on my blog. These have non-trivial implications for academic visibility/status. It’s hard to explore these issues conceptually and empirically if the debate is polarised into abolitionists and solutionists, such that if you’re not one you are immediately suspected of being the other.

The 2025 growing season is officially started
First seeds in cold stratification some seeds require dry stratification and some require wet/moist stratification. Also the length of the stratification can be up to 3 months
This growing season I'm starting more than 400 varieties of seeds doubling last year selection

@Lstn2urmama I don't have time for cactus. I just opened the fridge to check my stratification seeds. I have some planting to do today, these appeared

LRT: Oh, right...I totally forgot about the #AppleEvent today. I guess I'll watch the keynote while I eat dinner and try not to throw my food and utensils at #TimCook's smug arrogant face. He really is the insidiously worst thing to ever happen to #Apple. Even #SteveJobs wasn't as much of a prick as Tim Cook, and Jobs set a high bar for that. Jobs' saving grace was, his company produced amazing products for normal people. Cook's company blatantly creates social #stratification for profit.

My tiny #apple orchard.
Unintentional early #trees (#Treelings), from #seed. Usually, I won't grow until March, as there is insufficient sunlight to promote growth. Winter #apples are shipped and stored just above freezing. You can guess how old the Fresh Produce actually is, based on the fact that apple #seeds need about 90 days of near, or below freezing temperatures for #stratification (to sprout) four trees (so far) that I am #growing here, sprouted in apples purchased in recent week.

« Stratification theories suggest that social background and cumulative advantage dominate cognitive ability as determinants of high occupational success. This leads us to hypothesize that among the relatively successful, average ability is concave in income and prestige. »
