Mapping murders: this new data tool is helping cities understand violent crime

To address the food insecurity problem among its low-income students, Columbia University launched Swipes, a meal sharing app in which students with a surplus of “meal swipes” could donate them to students in need. But when that app struggled to function and roll out properly, Columbia looked downtown to New York University, where student Jon Chin launched a similarly purposed but more effectively designed app, Share Meals. So far, the app has enabled over a thousand meal donations, and is hoping to work with Columbia to share its code and expand its donor services.

Corruption in Mexico is ingrained in all systems and interactions. President Vicente Fox and his administration are trying to change this. Their mentality is that for corruption to truly be fought the government needs to actively make change and implement rules to counteract it, and some of Fox's changes are now beginning to see improvements.

Protected species of animals and plants are illegally sold online mainly due to buyers and sellers having no knowledge of laws or the consequences to the ecosystem. Enforcement Gaps Interface (EGI) is a software which uses machine learning to determine if the animal product is illegal or not.

Despite advancements in technology in most sectors of life leading to an increase to access of information about practically anything, little is still known about the ocean and its behavioral patterns. Liquid Robotics – a Silicon Valley-based company – is trying to change that. Engineers here have created the "Wave Glider," which essentially acts as a router within the ocean powered by wave energy and solar panels. This invention can transmit data on tectonic activity that has the potential to predict tsunamis.

The Kansas City school district and a group of local nonprofits are implementing a new software management system that will allow partners to access student data from a range of sources. The data-sharing agreement will paint a more holistic picture of students and, in the future, allow teachers and others to make informed interventions when appropriate.

Using data collection and visualization, apps like SafeCity, HarassMap, and #WalkFreely are crowdsourcing locations where individuals have been sexually harassed or assaulted so that others know to take precautions. Some operate on a global scale, others locally, but what they all offer is a platform for people to share their story and hopefully prevent it from happening again. Such apps have led to action from community members, the media, and officials who have taken notice of the high rates in certain places and taken action.

In Rochester, NY, the Center for Teen Empowerment, a nonprofit that trains youth in community organizing, personal development, and anti-violence, is working to bring kids off the street and into safety. The program, which started in Boston, is centered on four ideas: jobs (paying the youth hired as organizers), teamwork, agency (letting them build their own activist agendas), and peer influence. While hard to evaluate because of its situational, qualitative nature, city officials, including law enforcement, point to the program as a factor in the decrease in violence across the city.

A growing number of governments, companies, and nonprofit organizations are working together with new technology and data to identify fishing vessels that are breaking laws and engaging in human rights violations. Using satellite imagery and tracking signals, for example, a philanthropic company and a nonprofit worked with the UN Office on Drugs and Crime to help the Ghanian navy arrest four vessels for illegal fishing practices. Technology by itself won’t stop forced labor and unregulated ships, but it can be helpful for cash-strapped governments looking to increase oversight of their fisheries.

A data analyst who is a Microsoft-certified trainer uploads videos on social media teaching digital technology skills in the Yorùbá language. The videos are free to watch and break the language barrier that arises with most English-only tech information available online.

Grand Rapids is working to reform behavioral health services and the way law enforcement interacts with those in a mental health crisis through efforts like its county-run crisis access center. An increased need has led to an expansion of these programs, and the city now has a psychiatric urgent care center, mobile crisis teams that make house calls, social workers who join the police on 911 calls and plans for a 24/7 behavioral health crisis center that will open in November.
