This new research identifies online competency-based learning as the solution to shifting demands for specialized workforce skills and the front runner for disrupting higher education

NOSQL design for analytical workloads: Variability matters

Big Data has recently gained popularity and has strongly questioned relational databases as universal storage systems, especially in the presence of analytical workloads. As result, co-relational alternatives, commonly known as NOSQL (Not Only SQL) databases, are extensively used for Big Data. As the primary focus of NOSQL is on performance, NOSQL databases are directly designed at the physical level, and consequently the resulting schema is tailored to the dataset and access patterns of the problem in hand. However, we believe that NOSQL design can also benefit from traditional design approaches. In this paper we present a method to design databases for analytical workloads. Starting from the conceptual model and adopting the classical 3-phase design used for relational databases, we propose a novel design method considering the new features brought by NOSQL and encompassing relational and co-relational design altogether.Peer ReviewedPostprint (author's final draft

Suppressing Protest: Human Rights Violations in the U.S. Response to Occupy Wall Street

In September 2011, waves of protests against mounting socioeconomic injustice broke out across the United States, capturing the attention of the country. The Occupy Wall Street movement, inspired by similar protests around the globe, used the occupation of public space and mass demonstrations to call attention to a wide array of shared concerns. The movement also used public assemblies to debate concerns and promote direct democratic participation. Within weeks of their emergence, the protests dramatically expanded and deepened U.S. political discourse around the widening gap between rich and poor, bank bailouts and impunity for financial crimes, and the role of money in politics. The response of U.S. authorities to the protests also received significant attention. Images of police using pepper spray on seated students, the arrests of thousands of peaceful protesters across the country, midnight raids on encampments, baton-swinging officers, marches accompanied by phalanxes of riot police, and officers obstructing and arresting journalists were beamed around the world. This is the first in a series of reports examining the responses of U.S. authorities to the Occupy protests. Through an eight-month-long study of the response in New York City, together with comparative data collected from cities across the United States, this report highlights major policy concerns and serious violations of the rights of protesters. Further detailed studies will be published in the coming months on the response of authorities in Boston, Charlotte, Oakland, and San Francisco. Government responses to Occupy Wall Street in the United States have varied significantly, both within and across cities. Indeed, there have been examples of good practice, including through welcoming assemblies, using modern democratic policing styles that promote negotiation to facilitate protests, and enforcing strict controls on any use of police force. But across the United States, abusive and unlawful protest regulation and policing practices have been and continue to be alarmingly evident. This report follows a review of thousands of news reports and hundreds of hours of video, extensive firsthand observation, and detailed witness interviews

Montessori Green School Initiative Mapping Project

The Montessori Green School Initiative Mapping Project, carried out for the Montessori School in Redlands, is one part of the Green School Initiative, which integrates efforts to reduce the school’s ecological footprint, helps create a healthier school environment, and gets the community thinking about solutions to sustainability problems. This mapping project is important because it helps the students in visualizing concepts via maps, which is a good way to involve children early in map reading skills and environmental awareness. This helps perpetuate the ecological movement of saving the planet. The Montessori School’s primary problem was the inability for the faculty, students, and parents to visualize the school’s twenty-six acres of data geographically. The school needed help implementing the initiative strategically, so analysis was an important part of their conservation objective and in determining and implementing some of the key areas of the Montessori’s Green School Initiative (GSI). The client required a system that combined environmental education with mapping and analysis techniques, while utilizing geographic information system (GIS) over the web. The categorized trees, campus, and usage data, as well as the carpool and “Safe Bike Bus” maps, supply their website with the information they need to help the environment. The resultant is the ability to edit the tree characteristics (category, type, size, health, diameter, and mineral deficiency), and the ability to update and analyze their utility and usage data over a web-based GIS system

Navigating multilingual news collections using automatically extracted information

We are presenting a text analysis tool set that allows analysts in various fields to sieve through large collections of multilingual news items quickly and to find information that is of relevance to them. For a given document collection, the tool set automatically clusters the texts into groups of similar articles, extracts names of places, people and organisations, lists the user-defined specialist terms found, links clusters and entities, and generates hyperlinks. Through its daily news analysis operating on thousands of articles per day, the tool also learns relationships between people and other entities. The fully functional prototype system allows users to explore and navigate multilingual document collections across languages and time.Comment: This paper describes the main functionality of the JRC's fully-automatic news analysis system NewsExplorer, which is freely accessible in currently thirteen languages at http://press.jrc.it/NewsExplorer/ . 8 page

Towards a Gold Standard Corpus for Variable Detection and Linking in Social Science Publications

In this paper, we describe our effort to create a new corpus for the evaluation of detecting and linking so-called survey variables in social science publications (e.g., "Do you believe in Heaven?"). The task is to recognize survey variable mentions in a given text, disambiguate them, and link them to the corresponding variable within a knowledge base. Since there are generally hundreds of candidates to link to and due to the wide variety of forms they can take, this is a challenging task within NLP. The contribution of our work is the first gold standard corpus for the variable detection and linking task. We describe the annotation guidelines and the annotation process. The produced corpus is multilingual - German and English - and includes manually curated word and phrase alignments. Moreover, it includes text samples that could not be assigned to any variables, denoted as negative examples. Based on the new dataset, we conduct an evaluation of several state-of-the-art text classification and textual similarity methods. The annotated corpus is made available along with an open-source baseline system for variable mention identification and linking

Prochlo: Strong Privacy for Analytics in the Crowd

The large-scale monitoring of computer users' software activities has become commonplace, e.g., for application telemetry, error reporting, or demographic profiling. This paper describes a principled systems architecture---Encode, Shuffle, Analyze (ESA)---for performing such monitoring with high utility while also protecting user privacy. The ESA design, and its Prochlo implementation, are informed by our practical experiences with an existing, large deployment of privacy-preserving software monitoring. (cont.; see the paper
