The common thinking on biological sex goes like this: females have two X chromosomes in their cells, while males have one X and one Y. In this myth-busting talk, science writer and podcaster Molly Webster shows why the so-called "sex chromosomes" are more complicated than this simple definition -- and reveals why we should think about them differently.

The world is more connected than ever, but some communities are still cut off from vital resources like electricity and health care. In this solution-oriented talk, activist Johanna Figueira discusses her work with Code for Venezuela -- a platform that gathers technologists to address Venezuela's needs for information and medical supplies -- and shares ideas for how it could be used as a model to help other communities in need.

Reconnecting with mentors, friends, coaches and professors, these football greats reflected on the experiences that they carried with them well beyond their college years. While they all share different stories, their journeys to the NFL were each met with adversity, and whether on or off the field, these obstacles served as tests for each individual athlete to overcome. These challenges made them stronger, earning them valuable lessons and helping them create special connections with the university they will always call ‘home.’

Classrooms across Washington state sat empty last week, as teachers in seven districts went on strike when negotiations over salaries and benefits failed to result in contracts by the first day of school.

Members of 30 different state and national advocacy groups and unions are meeting in Washington, D.C., for the Grassroots Assembly for Child Care and Early Education.

Consumers who only make the minimum repayment on their credit card could be paying hundreds of dollars a year in high interest payments. To help, BETA partnered with the Treasury and Westpac to see if reminders could encourage consumers to pay earlier and save money. We found any type of SMS reminder resulted in a $134 (28 per cent) increase in repayments in the following month, compared to those who received no message. However, different SMS messages all had a similar impact and we were unable to detect an effect from sending email reminders. Overall, the findings suggest that sending an SMS reminder to credit card consumers before their payment due date is a simple, cost-effective way to improve their financial wellbeing.

Two Aboriginal Elders, one of whom had been removed from her family as a child, and the other who was affected by siblings and other family members being removed, provided consent to share their personal stories specifically for this resource, with the vision that people would be better informed and communication improved when delivering care. To respect their privacy, their stories have been de-identified.

We consider the skill rating problem for multiplayer games, that is how to infer player skills from game outcomes in multiplayer games. We formulate the problem as a minimization problem $arg min_{s} s^T Delta s$ where $Delta$ is a positive semidefinite matrix and $s$ a real-valued function, of which some entries are the skill values to be inferred and other entries are constrained by the game outcomes. We leverage graph-based semi-supervised learning (SSL) algorithms for this problem. We apply our algorithms on several data sets of multiplayer games and obtain very promising results compared to Elo Duelling (see Elo, 1978) and TrueSkill (see Herbrich et al., 2006).. As we leverage graph-based SSL algorithms and because games can be seen as relations between sets of players, we then generalize the approach. For this aim, we introduce a new finite model, called hypernode graph, defined to be a set of weighted binary relations between sets of nodes. We define Laplacians of hypernode graphs. Then, we show that the skill rating problem for multiplayer games can be formulated as $arg min_{s} s^T Delta s$ where $Delta$ is the Laplacian of a hypernode graph constructed from a set of games. From a fundamental perspective, we show that hypernode graph Laplacians are symmetric positive semidefinite matrices with constant functions in their null space. We show that problems on hypernode graphs can not be solved with graph constructions and graph kernels. We relate hypernode graphs to signed graphs showing that positive relations between groups can lead to negative relations between individuals.

Abstract:
Strategies to prevent cancer and diagnose it early when it is most treatable are needed to reduce the public health burden from rising disease incidence. Risk assessment is playing an increasingly important role in targeting individuals in need of such interventions. For breast cancer many individual risk factors have been well understood for a long time, but the development of a fully comprehensive risk model has not been straightforward, in part because there have been limited data where joint effects of an extensive set of risk factors may be estimated with precision. In this article we first review the approach taken to develop the IBIS (Tyrer–Cuzick) model, and describe recent updates. We then review and develop methods to assess calibration of models such as this one, where the risk of disease allowing for competing mortality over a long follow-up time or lifetime is estimated. The breast cancer risk model model and calibration assessment methods are demonstrated using a cohort of 132,139 women attending mammography screening in the State of Washington, USA.
