An ultrasonic body area network for implants

An ultrasonic body area network for implants | biglife | Scoop.it

Researchers at the University at Buffalo aredeveloping a “body area network” using ultrasonic waves and sensors to wirelessly share information between medical devices implanted in (or worn by) people to treat diseases such as diabetes and heart failure.

 

“This is a biomedical advancement that could revolutionize the way we care for people suffering from the major diseases of our time,” said Tommaso Melodia, PhD, UB associate professor of electrical engineering.

 

The idea of creating a network of wireless body sensors, also called a “body area network,” currently links sensors together via electromagnetic radio-frequency waves — similar to those used in cellular phones.

 

Radio waves have drawbacks such as the heat they generate, and because they propagate poorly through skin, muscle and other body tissue, they require relatively large amounts of energy, he said.

 

Ultrasound may be a more efficient way to share information, Melodia said, because roughly 65 percent of the body is composed of water. This suggests that medical devices, such as a pacemaker and an instrument that measures blood oxygen levels, could communicate more effectively via ultrasound compared to radio waves.

 

“Think of how the Navy uses sonar to communicate between submarines and detect enemy ships,” Melodia said. “It’s the same principle, only applied to ultrasonic sensors that are small enough to work together inside the human body and more effectively help treat diseases.”

 

Another example involves connecting blood glucose sensors with implantable insulin pumps. The sensors would monitor the blood and regulate, through the pumps, the dosage of insulin as needed in real time.

Can a “Like” Save a Life?

Can a “Like” Save a Life? | biglife | Scoop.it

 

UNICEF Sweden issued a bold call to its social media supporters two months ago: Don’t “Like” us; give us your money.

 

Though it likely caused more uproar among those of us in the “social media for social good” community than among the organization’s own supporters, it certainly raised some important questions about the potential trade-off of encouraging online support at the expense of offline support, and of the growing value of influence relative to other contributions and individual can make.

 

We explored many of these same questions in a study that Georgetown University’s Center for Social Impact Communication conducted last summer in partnership with Waggener Edstrom Worldwide. We wanted to gain insights into the “engagement life cycle” (from learning about a cause, to deciding if and how to support it, to perceptions of personal impact) among the highly desirable group of individuals who are both active participants in social media and active supporters of charitable organizations and campaigns. The “Digital Persuasion” survey, fielded among 2,000 American adults, yielded a wealth of nuanced data and further illuminates some important trends.

Leaders Everywhere: A Conversation with Gary Hamel (Video) | biglife | Scoop.it

The latest M-Prize challenge, cosponsored by Gary Hamel’s Management Innovation eXchange (MIX), Harvard Business Review, and McKinsey, asks managers to submit examples of how their organizations are empowering and training individuals to lead even when they lack formal authority. In this video, Professor Hamel discusses why he believes it is vital for companies to “syndicate the work of leadership” across the organization, to redistribute power, and to change the role of the top team. This interview was conducted by McKinsey Publishing’s Simon London. What follows is an edited transcript of Hamel’s remarks.

The Inside and Outside View of Innovation

The Inside and Outside View of Innovation | biglife | Scoop.it

 

How can companies ensure that a promising initiative receives the necessary resources? And why do so many brilliant inventions fail while other seemingly mediocre offerings succeed? Such questions are addressed in two recent books — Unrelenting Innovation: How to Build a Culture for Market Dominance, by Gerard J. Tellis and The Wide Lens: A New Strategy for Innovation, by Ron Adner. The first book concentrates on a company’s internal workings, while the latter focuses on its external environment.

 

In Unrelenting Innovation, Tellis asserts that the single most important driver of innovation in any organization is its culture, and he cites three organizational traits important for innovation: a willingness to cannibalize existing products, a risk-taking attitude and the ability to focus on the future. Many companies have a hard time commercializing radical innovations, Tellis notes, because these would hurt the company’s existing products. To counter such tendencies, Tellis offers three practices: providing the right incentives, fostering internal markets and empowering “innovation champions” within the organization.

Mental Health Issues: Staff Engagement Survey Reveals Lack of Transparency

Mental Health Issues: Staff Engagement Survey Reveals Lack of Transparency | biglife | Scoop.it

Evidence for strong employee engagement levels has never been clearer, with recent research conducted by Business in the Community (BITC) and Ipsos Mori indicating a critical link between strong human capital management and organisational performance.

 

FTSE 100 companies that have robust arrangements for reporting on employee wellness and engagement have been found to outperform the rest by 10%. We also know that investors are demanding a clearer and more consistent way to understand how organisations are managing their most important asset – people. But there is a lack of transparency in public reporting about employee engagement and wellbeing.

 

In April, BITC published the Workwell FTSE 100 benchmarking results, which track companies' public reporting in five key areas: better physical and psychological health, better work, better specialist support, better relationships and working well.

Energy Efficiency Can Make Billions While Fighting Climate Change | biglife | Scoop.it
Energy efficiency could be a huge investment opportunity in the U.S., but better policies are needed to unlock financing, according to a new Ceres study.


Energy efficiency could be a several hundred billion dollar investment opportunity in the United States, but better policies are required to unlock broad-based financing from institutional investors, according to a new study by investor advocacy group Ceres.

The study details the results of a survey of nearly 30 institutional investors and other experts from the energy, policy and financial sectors that identified three areas of policy:

utility regulationdemand-generating policies and innovative financing policies


The study finds that these three areas have the potential to take energy efficiency financing to a scale sufficient enough to attract significant institutional investment.
