Uber had pioneered the growth and delivery of modern ridesharing services by leveraging the explosive growth of technology, GPS navigation, and smartphones. Ridesharing services had expanded across the world, growing rapidly in the United States, China, India, Europe, and Southeast Asia. Even as these services expanded and gained popularity, however, the pickup experience for drivers and riders did not always meet the expectations of either party. Pickups were complicated by traffic congestion, faulty GPS signals, and crowded pickup venues. Flawed pickups resulted in rider dissatisfaction and in lost revenues for drivers. Uber had identified the pickup experience as a top strategic priority, and a team at Uber, led by group product manager Birju Shah, was tasked with designing an automated solution to improve the pickup experience. This involved three steps. First, the team needed to analyze the pickup experience for various rider personas to identify problems at different stages in the pickup process. Next, it needed to create a model for predicting the best rider location for a pickup. The team also needed to develop a quantitative metric that would determine the quality of the pickup experience. These models and metrics would be used as inputs for a machine learning.

Longitudinal Association

The prevalence of prediabetes and diabetes in the United States and around the world has increased faster than expected in the last 30 years. The economic burden this costs a nation can be astronomic both in terms of expense and loss in productivity. One-third of U.S. adults, 86 million people, have prediabetes. Effective management is needed that can reach these 86 million, and others at high risk, to reduce their progression to diagnosed Type 2 diabetes. After the literature review, there was not enough literature to support how these led to the progression to diabetes. The abundant literature is centered on how to prevent complications and improve the quality of life of those living with type 2 diabetes. This paper will focus on the longitudinal association between these social determinants and how they may predispose to the progression to Type 2 diabetes.

Clinical Islet Transplantation ◽  
The World

Clinical islet transplantation was first realized over four decades ago at the University of Minnesota. Autologous islet transplantation is now widely recognized as a treatment to prevent diabetes in patients after pancreas excision and is offered at major transplant centers throughout the United States and the world. Type 1 diabetes represents a much larger demographic in which islet transplantation may benefit patients. Allogeneic islet transplantation can now offer similar outcomes to pancreas transplantation in a subset of patients with labile type 1 diabetes with less risk than whole organ transplantation. It is recognized as a standard of care in nations around the world but not in the United States, despite the important developmental role US scientists and physicians have played. Early reports of islet transplantation focused on insulin independence that proved to diminish over time. However, regardless of insulin status, islet transplantation provides benefits ranging from improved quality of life to reduction in diabetic complications. A National Institutes of Health sponsored multi-center Phase 3 Clinical Trial (CIT-07) demonstrated safety and efficacy, although the Food and Drug Administration chose to consider islets as a biologic that requires licensure, which makes offering the procedure in the clinic very challenging. Until regulations can be brought into communion with international standards, allogeneic islet transplantation in the United States is unlikely to match international levels of success and once promising programs are left to wither on the vine. Food and Drug Administration approval would open the door for third party medical reimbursement and allow many patients the opportunity to enjoy better health and quality of life. Establishment of clinical islet transplantation for type 1 diabetes would lead to optimizations in procedures making it more efficacious and cost effective while offering support for ongoing islet xenotransplantation studies that could bring islet transplantation to even more patients.

Can risk assessment be made fair? The conclusion of Calculating Race returns to actuarial science’s foundations in probability. The roots of probability rest in a pair of problems posed to Blaise Pascal and Pierre de Fermat in the summer of 1654: “the Dice Problem” and “the Division Problem.” From their very foundation, the mathematics of probability offered the potential not only to be used to gain an advantage (as in the case of the Dice Problem), but also to divide material fairly (as in the case of the Division Problem). As the United States and the world enter an age driven by Big Data, algorithms, artificial intelligence, and machine learning and characterized by an actuarialization of everything, we must remember that risk assessment need not be put to use for individual, corporate, or government advantage but, rather, that it has always been capable of guiding how to distribute risk equitably instead.

We have kept our republic through a variety of localized disasters and various problem elections. The research presented here highlights the field of “Election Science and Administration” (ESA). Research in our field maximize our probability of continuing to keep our republic—even in the face of a pandemic which is a national—and international challenge. As the United States and the world deal with the specter of a pandemic election, the growth of the scholarly field designed to advocate for transparency in data collection and to improve the quality of elections is more important than ever.

There are only a few countries in the world in which education is not the responsibility of national governments but the responsibility of smaller units—provinces and territories in Canada and states in Australia and the United States. Canada has 10 provinces and three territories; hence, there are 13 systems of public education with about 5.5 million students and over 450,000 teachers (Canadian Education Statistics Council, 2020). Consequently, there is considerable variability across the country in the quality of education and in the way it is managed and delivered.

Newspaper Articles

This chapter confirms that Muslim newspaper articles in Britain, Canada, and Australia are similar to those in American newspapers. Patterns in both the amount and the tone of coverage closely parallel our US findings, as do the factors associated with the greatest negativity, and the words most commonly used to describe Muslims or Islam. A probe into six newspapers from South Asia, Southeast Asia, and Africa, however, demonstrates that coverage of Muslims is not simply dictated by world events. In most of these newspapers, coverage of Muslims remains negative on average, but this negativity is simply far less intense than in the Anglophone North. In addition, the specific words most commonly associated with Muslims and Islam in these six newspapers are much more varied. Media around the world have more latitude to select stories and to frame discussions than an analysis of Anglophone North newspapers alone would imply.

Almost every country in the world publishes official documents of some kind or another. There is much in these documents of interest to law libraries because they normally include official texts of codes, laws, and subordinate legislation, official court and government reports, statistics, and official gazettes or other official publications of periodical or serial nature. The content of some of these publications can be of considerable legal importance, but their usefulness is limited unless they can also be identified and acquired with relative ease. Unfortunately, this is not true for documents of most countries. The root of the problem is that very few countries, e. g., Canada, Federal Republic of Germany, Netherlands, the United Kingdom, the United States, etc. are in the habit of regularly publishing bibliographies, catalogs or other “search aids” for their documents. In most countries such bibliographic information, if available at all, tends to be incomplete, inaccurate, and sporadic. Finding a document (or even finding out about its existence) in such circumstances becomes more a matter of luck than the result of a skillful professional search.

Abstract Health care within jails and prisons in the United States is typically insufficient to meet the medical and psychological needs of female inmates. Health services are often of low quality, especially in the areas of reproductive medicine. Mental illness, substance abuse, a trauma history, and sexual victimization while incarcerated can predict a more difficult adjustment to a correctional environment. Incarcerated women who are able to maintain contact with family members, especially children, can have a better prison adjustment. Recommendations are made to improve the types and quality of health care delivered to women in jails and prisons in countries around the world.
