(Press-News.org) New Rochelle, October 29, 2014 –Cities around the world are increasingly making urban data freely available to the public. But is the content or structure of these vast data sets easy to access and of value? A new study of more than 9,000 data sets from 20 cities presents encouraging results on the quality and volume of the available data and describes the challenges and benefits of analyzing and integrating these expanding data sets, as described in an article in Big Data, the highly innovative, peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The Open Access article is available free on the Big Data website.
In the article "Structured Open Urban Data: Understanding the Landscape," Luciano Barbosa and Marcos Vieira, IBM Research, Brazil, and Kien Pham, Claudio Silva, and Juliana Freire, New York University School of Engineering and NYU Center for Urban Science and Progress, NY, present several promising findings. These include a steadily increasing volume of open urban data, the ability to integrate different data sets, and the finding that much of the available data is published in standard types of formats. The authors also discuss the main challenges that make it difficult to take full advantage of these data sources.
"Big urban data is a powerful new phenomenon that has the potential to transform everyday lives of hundreds of millions of people quickly via personal devices that integrate, filter, and create useful personalized information. This paper documents the sources and value of these data," says Big Data Editor-in-Chief Vasant Dhar, Co-Director, Center for Business Analytics, Stern School of Business, New York University.

To reap the brain benefits of physical activity, just get moving!
2014-10-29
This news release is available in French. Everyone knows that exercise makes you feel more mentally alert at any age. But do you need to follow a specific training program to improve your cognitive function? Science has shown that the important thing is to just get moving. It's that simple. In fact, this was the finding of a study conducted at the Institut universitaire de gériatrie de Montréal (IUGM), an institution affiliated with Université de Montréal, by Dr. Nicolas Berryman, PhD, Exercise Physiologist, under the supervision of Dr. Louis Bherer, ...
Meiotic cell division 'the other way round'
2014-10-29
This news release is available in German. Meiosis is not like another: Gabriela Cabral and Peter Schlögelhofer at the Max F. Perutz Laboratories (MFPL) of the University of Vienna and the Medical University of Vienna dived into the process of meiosis in specific plant species and revealed that these plants display an inversion of the standard meiotic phases. The researchers describe the detailed mechanisms in the scientific journal Nature Communications.
Meiosis is the two-step series of cell divisions that make sexual reproduction and genetic diversity possible.The ...
A mechanism that allows a differentiated cell to reactivate as a stem cell revealed
2014-10-29
One kind of stem cell, those referred to as 'facultative', form part—together with other cells—of tissues and organs. There is apparently nothing that differentiates these cells from the others. However, they have a very special characteristic, namely they retain the capacity to become stem cells again. This phenomenon is something that happens in the liver, an organ that hosts cells that stimulate tissue growth, thus allowing the regeneration of the organ in the case of a transplant. Knowledge of the underlying mechanism that allows these cells to retain this ...
Cinema-like environment helps audiences immerse in movies even on small screens & displays
2014-10-29
If the surroundings are designed to be sufficiently stimulating, even a simple computer screen is enough to generate an intense cinematic experience. After observing some 300 study subjects, researchers at the Institute of Psychology of Johannes Gutenberg University Mainz (JGU) in Germany concluded that the angle of viewing does not play a vital role in the cinematic experience, thus disproving various hypotheses. According to the results of their study, the presence of so-called contextual visual cues plays a greater role in actually drawing viewers into a movie. When ...
Projecting a robot's intentions
2014-10-29
In a darkened, hangar-like space inside MIT's Building 41, a small, Roomba-like robot is trying to make up its mind.
Standing in its path is an obstacle — a human pedestrian who's pacing back and forth. To get to the other side of the room, the robot has to first determine where the pedestrian is, then choose the optimal route to avoid a close encounter.
As the robot considers its options, its "thoughts" are projected on the ground: A large pink dot appears to follow the pedestrian — a symbol of the robot's perception of the pedestrian's position in space. ...
Walking workstations improve physical and mental health, builds healthier workplace
2014-10-29
Walking workstations can improve not only physical, but also mental health during the workday, a new study released this week found. The research was conducted by faculty and student researchers from the Department of Psychology in the School of Science at Indiana University-Purdue University Indianapolis (IUPUI).
With growing concerns regarding obesity in the United States, Michael Sliter, assistant professor of psychology, hopes the study encourages employers to examine methods to assist workers in in healthy living.
"We found that the walking workstations, regardless ...
Go straight and publish: From Barcode of Life Data Systems to scholarly publishing systems
2014-10-29
An innovative workflow reveals new research potential of the Barcode of Life Data Systems (BOLD). A recently published article in the Biodiversity Data Journal (BDJ) used specimen records downloaded from BOLD in tabular format and imported these into a human-readable text developed in manuscript within the Pensoft Writting Tool (PWT). Data were used to study the species distributions of ten Nearctic species of braconid wasps from the Microgastrinae subfamily.
BOLD is originally designed to support the generation and application of DNA barcode data. However, the repository ...
Saving lots of computing capacity with a new algorithm
2014-10-29
The control of modern infrastructure such as intelligent power grids needs lots of computing capacity. Scientists of the Interdisciplinary Centre for Security, Reliability and Trust (SnT) at the University of Luxembourg have developed an algorithm that might revolutionise these processes. With their new software the SnT researchers are able to forego the use of considerable amounts of computing capacity, enabling what they call micro mining. Their achievements, which the team headed by Prof. Yves Le Traon published in the International Conference on Software Engineering ...
NYU research: Tourism as a driver of illicit drug use, HIV risk in the DR
2014-10-29
The Caribbean has the second highest global human immunodeficiency virus (HIV) prevalence in the world outside of Sub-Saharan Africa, with HIV/AIDS as leading cause of death among people aged 20–59 years within the region. Particularly hard-hit are the Dominican Republic (DR) and Haiti, on the island of Hispaniola, accounting for approximately 70% of all people living with HIV in the Caribbean region.
Insufficient attention has been paid to the intersection of drugs and tourism as contributing factors for the region's elevated HIV/AIDS risk. Caribbean studies ...
Prenatal phthalate exposures and anogenital distance in Swedish boys
2014-10-29
The first study to examine prenatal exposure to the phthalate DiNP finds it is associated with a shorter anogenital distance (AGD) in Swedish boys at the age of 21 months. These findings raise concern since animal research has linked DiNP exposure to a shorter AGD, and studies on humans have related shorter AGD to male genital birth defects as well as impaired reproductive function in adult males, and the levels of DiNP metabolites in humans are increasing globally.
Background
Phthalates are used as plasticizers in soft polyvinyl chloride (PVC) and found in a large ...
