Unicef recruits gamers to mine Ethereum in aid of Syrian children

Cryptocurrency scheme is part of wider UN effort to revolutionise aid with blockchain technology, increasing financial transparency

The UN’s children’s agency, Unicef, has launched a futuristic pilot project to utilise the cryptocurrency Ethereum to raise money for Syrian children.

the “blockchain” technology associated with the cryptocurrency – the world’s second largest after the controversial Bitcoin – to revolutionise not only how aid organisations raise money but also to increase transparency in their financial transactions.

Blockchain – which emerged as one of the underpinnings of Bitcoin – is a shared record of transactions maintained by a network of computers. It has become a key technology because of its ability to record and keep track of assets or transactions with no need for middlemen.

With a valuation of some $88bn (£62bn), Ethereum – which launched in 2015 – has an equivalent market value to Starbucks, according to Forbes magazine

The World Food Programme (WFP) has used Ethereum to deliver $1.4m in food vouchers, via the use of iris recognition scanners in camp supermarkets, to around 10,000 Syrian refugees in Jordan,

a twist in cyberbullying

A new twist on cyberbullying

By Cynde Reneau 1/17/2018 Digital citizenship Standards

Just as in the 1970s, when antidrug campaigns were scoffed at by the very people they were targeting, anti-bullying campaigns are also losing their effectiveness. I got a taste of this firsthand last year when I spoke about sexting, online safety and cyberbullying at an all-school assembly. When a student blurted out an obscenity during the sexting portion, the students went wild and didn’t listen to a thing I said. I was frustrated and discouraged. Later, I offered an iPad mini to the student who produced the best video and poster. Even that got little response.

The fact is, anti-bullying clichés have become a shut-off switch. What we really need to be doing is giving students actual skills to prevent bullying. To get that conversation going, I pose this question to students: “Will you accept the identity that others give you?”

Russia’s Sberbank plans cryptocurrency exchange in Switzerland

PUBLISHED 03:43 FEBRUARY 6, 2018

Moscow appears to have moved quickly into the market of cryptocurrencies and cryptography. Gref earlier warned that companies including Blockchain and Bitcoin should not be banned or hindered in their operations.

Russia’s Finance Ministry legalised cryptocurrency trading on January 25 with the Digital Assets Regulation Bill, despite vocal objections from the country’s Central Bank. The bill defined cryptocurrencies and tokens as digital financial assets that are not legal tender in Russia. The Central Bank, however, argued that digital currency trading rules should only be applied to tokens that would attract financial investments.

Subject: Re: [lita-l] Using Raspberry Pi(s) w/ Sensors to Obtain Counts on Occupancy in a Library Space

Berika,

We’re currently experimenting/piloting with RPis, the RPi camera module, and this code:

https://github.com/WatershedArts/Footfall

It’s working, generally, but it does require a good bit of config tweaking to get it to accurately count. It also needs (I’ve discovered) a certain amount of distance between the door and the camera. We have very low ceilings at our doorways and a single person can span the entire frame which appears to confuse the software. All that being said, it’s very much worth looking into.

Analytics out of the box aren’t great. The only built in report is only the current day’s numbers, but it’s pretty easy to export data. We have Libinsight from Springshare and I’m working on pumping that data into their system. It is tricky because the system basically records two things: a timestamp, and a positive or negative integer depending on whether or not the traffic was going in or out. By default, no generic analytics system seems to understand that well enough to display it the way I’d like, so I may have to create some custom reports using d3.js or similar.

I’m using the Pi 2 and standard camera module from Adafruit. I’d be happy to answer questions.

Hi all,

We are trying to automate counting the number of people entering and leaving a

specific floor of our library. (The library is located in a multi-use

building.)

We’ve looked at the awesome “Measure the Future” code but we need analytics

more akin to a gate count versus tracking movement of people utilizing the

space.

Have any of you used raspberry pis or other technologies to do this type of

tracking?

If so, would you be willing to share your hardware/software setup with us and

also what type of data/analytics you’re getting back from the system?

Thank you,

Berika

The Implications of Brain Research for Distance Education

The brain is actually three brains: the ancient reptilian brain, the limbic brain, and the cortical brain. This article will focus on the limbic brain, because it may be most important to successfully using interactive video or web-based video. The limbic brain monitors the external world and the internal body, taking in information through the senses as well as body temperature and blood pressure, among others. It is the limbic brain that generates and interprets facial expressions and handles emotions, while the cortical brain handles symbolic activities such as language as well as action and strategizing. The two interact when an emotion is sent from the limbic to the cortical brain and generates a conscious thought; in response to a feeling of fear (limbic), you ask, “what should I do?” (cortical).

The importance of direct eye contact and deciphering body language is also important for sending and picking up clues about social context.

The loss of social cues is important because it may affect the quality of the content of the presentation (by not allowing timely feedback or questions) but also because students may feel less engaged and become frustrated with the interaction, and subsequently lower their assessment of the class and the instructor (Reeves & Nass, 1996). Fortunately, faculty can provide such social cues verbally, once they are aware of the importance of helping students use these new media.

Attachment theory also supports the importance of physical and emotional connections.

As many a struggling teacher knows, students are often impervious to learning new concepts. They may replay the new information for a test, but after time passes, they revert to the earlier (and likely wrong) information. This is referred to as the “power of mental models.” As explained in Marchese (2000), when we view a tree, it is not as if we see the tree in our head, as in photography.

The coping strategies of the two hemispheres are fundamentally different. The left hemisphere’s job is to create a belief system or model and to fold new experiences into that belief system. If confronted with some new information that doesn’t fit the model, it relies on Freudian defense mechanisms to deny, repress or confabulate – anything to preserve the status quo. The right hemisphere’s strategy is to play “Devil’s Advocate,” to question the status quo and look for global inconsistencies. When the anomalous information reaches a certain threshold, the right hemisphere decides that it is time to force a complete revision of the entire model and start from scratch (Ramachandran & Blakeslee, 1998, p. 136).

While much hemispheric-based research has been repudiated as an oversimplification (Gackenbach, 1999), the above description of how new information eventually overwhelms an old world view may be the result of multiple brain functions – some of which work to preserve our models and others to alter – that help us both maintain and change as needed.

Self-talk is the “the root of empathy, understanding, cooperation, and rules that allow us to be successful social beings. Any sense of moral behavior requires thought before action” (Ratey, 2001, p. 255).

Healy (1999) argues that based on what we know about brain development in children, new computer media may be responsible for developing brains that are largely different from the brains of adults. This is because “many brain connections have become specialized for . . . media” (p. 133); in this view, a brain formed by language and reading is different from a brain formed by hypermedia. Different media lead to different synaptic connections being laid down and reinforced, creating different brains in youngsters raised on fast-paced, visually-stimulating computer applications and video games. “Newer technologies emphasize rapid processing of visual symbols . . . and deemphasize traditional verbal learning . . . and the linear, analytic thought process . . . [making it] more difficult to deal with abstract verbal reasoning” (Healy, 1999, p. 142).
