This book examines how Indigenous Peoples around the world are demanding greater data sovereignty and challenging the ways in which governments have historically used Indigenous data to develop policies and programs.

In the digital age, governments are increasingly dependent on data and data analytics to inform their policies and decision-making.

However, Indigenous Peoples have often been the unwilling targets of policy interventions and have had little say over the collection, use and application of data about them, their lands and cultures. At the heart of Indigenous Peoples’ demands for change are the enduring aspirations of self-determination over their institutions, resources, knowledge and information systems.

With contributors from Australia, Aotearoa New Zealand, North and South America and Europe, this book offers a rich account of the potential for Indigenous Data Sovereignty to support human flourishing and to protect against the ever-growing threats of data-related risks and harms.

U.S. Health Care Spending Highest Among Developed Countries | Johns Hopkins Bloomberg School of Public Health

The United States, on a per capita basis, spends much more on health care than other developed countries; the chief reason is not greater health care utilization, but higher prices, according to a study from a team led by a JHSPH researcher.

Shortest Path Distance Approximation Using Deep Learning: Node2Vec | by Asutosh Nayak | Towards Data Science

This article is an implementation of a research paper titled “Shortest Path Distance Approximation using Deep Learning Techniques”, where the authors explain a new method to approximate the shortest path distance between the nodes of a graph. I will explain the paper and my implementation of it. You can find the project on my GitHub account here. First I will give an overview of the method proposed in this paper, then we will go through some of the concepts used in this paper to solve the problem and finally the implementation.

Liking/Learning gap

An example of the liking-learning gap: what students like is not what they learn from.

Students like graphics on slides, but seductive graphics (interesting but not relevant) hurt long-term recall in online courses, while more boring instructive, directly relevant graphics help.

Learning in double time: The effect of lecture video speed on immediate and delayed comprehension – Murphy – – Applied Cognitive Psychology – Wiley Online Library

Abstract
We presented participants with lecture videos at different speeds and tested immediate and delayed (1 week) comprehension. Results revealed minimal costs incurred by increasing video speed from 1x to 1.5x, or 2x speed, but performance declined beyond 2x speed. We also compared learning outcomes after watching videos once at 1x or twice at 2x speed. There was not an advantage to watching twice at 2x speed but if participants watched the video again at 2x speed immediately before the test, compared with watching once at 1x a week before the test, comprehension improved. Thus, increasing the speed of videos (up to 2x) may be an efficient strategy, especially if students use the time saved for additional studying or rewatching the videos, but learners should do this additional studying shortly before an exam. However, these trends may differ for videos with different speech rates, complexity or difficulty, and audiovisual overlap.
