UN Committee Finds Violation of Indigenous Peoples’ Right to Traditional Lands | ASIL

The community complained that the process killed their animals and plants, and had an adverse impact on the environment. The Committee found that Paraguay failed to prevent contamination in violation of the their right to traditional lands, and recommended that Paraguay complete the relevant criminal and administrative proceedings. This decision affirms that the term “home” in the context of the indigenous community should be interpreted “within the context of the special relationship between them and their territories including their livestock, crops and their way of life such as hunting, foraging and fishing.”

Running Machine Learning Projects: Things to know | by Prashant Mudgal | Oct, 2021 | Towards Data Science

In my experience, ML projects come in all shapes and sizes and vary greatly in their complexity. In the initial 2000/10s, the emphasis was on the model-centric approach which I always found a little bizarre as I heard umpteen times about the fancier models than the results(well, it was a different time and folks used to get awestruck when they would hear ML, AI, DS etc); slowly and steadily the focus has shifted to the result centric approach i.e. use whatever model you can but make use of the data and produce results that are directional, applicable, and coherent.

Neanderthals Hunted with Leaf-Shaped Spears, Archaeologists Say | Archaeology, Paleoanthropology | Sci-News.com

The artifact is 7.6 cm (3 inches) long, 4.1 cm (1.6 inches) wide, 0.9 cm (0.35 inches) thick, and has a mass of 28 grams.

“Our results document how the tool was made, used and why it was discarded,” Professor Conard said.

“Thanks to a series of four ESR-dates the find is securely dated to over 65,000 years ago.”

“Until now finds of leaf points were interpreted as belonging to the period between 45,000 and 55,000 years ago — the last cultural phase of Neanderthals in Central Europe,” he added.

“The new results demonstrate that our assumptions about the dating of the cultural groups of the late Neanderthals were wrong and need revision.”

Using detailed microscopic analyses, the researchers found that the leaf point was mounted on a wooden shaft.

“Damage to the tip indicates that the artifact was used as a hafted spear point, and that the spear was likely thrust into prey rather than being thrown,” they said.

“Neanderthals used plant-based glue and bindings made from plant fibers, sinew, or leather, to secure the leaf point to the spear.”

“They clearly used the spear for hunting. While they re-sharpened the tool it broke, leading to its discard.”
