Remember that a blockchain is an immutable, sequential chain of records called Blocks. They can contain transactions, files or any data you like, really. But the important thing is that they’re chained together using hashes.

Twenty years have passed since renowned Harvard Professor Larry Lessig coined the phrase “Code is Law”, suggesting that in the digital age, computer code regulates behavior much like legislative code traditionally did.These days, the computer code that powers artificial intelligence (AI) is a salient example of Lessig’s statement.
Good AI requires sound data.One of the principles,some would say the organizing principle, of privacy and data protection frameworks is data minimization.Data protection laws require organizations to limit data collection to the extent strictly necessary and retain data only so long as it is needed for its stated goal.
Preventing discrimination – intentional or not.
When is a distinction between groups permissible or even merited and when is it untoward? How should organizations address historically entrenched inequalities that are embedded in data? New mathematical theories such as “fairness through awareness” enable sophisticated modeling to guarantee statistical parity between groups.
Assuring explainability – technological due process.In privacy and freedom of information frameworks alike, transparency has traditionally been a bulwark against unfairness and discrimination.As Justice Brandeis once wrote, “Sunlight is the best of disinfectants.”
Deep learning means that iterative computer programs derive conclusions for reasons that may not be evident even after forensic inquiry.
Yet even with code as law and a rising need for law in code, policymakers do not need to become mathematicians, engineers and coders.Instead, institutions must develop and enhance their technical toolbox by hiring experts and consulting with top academics, industry researchers and civil society voices.Responsible AI requires access to not only lawyers, ethicists and philosophers but also to technical leaders and subject matter experts to ensure an appropriate balance between economic and scientific benefits to society on the one hand and individual rights and freedoms on the other hand.
Others have likened habitual Facebook use to a mental disorder, comparing it to drug addiction and even publishing magnetic-resonance images of what Facebook addiction “looks like in the brain.”
For abstainers, breaking up with Facebook freed up about an hour a day, on average, and more than twice that for the heaviest users.
research led by Ethan Kross, a professor of psychology at the University of Michigan, has found that high levels of passive browsing on social media predict lowered moods, compared to more active engagement.
Weakest students more likely to take online college classes but do worse in them
Survey of rigorous academic research on online education finds lower grades and higher drop out rates Column by JILL BARSHAY February 4, 2019
According to the most recent federal statistics from 2016, roughly one out of every three or 6.3 million college students learned online. That number is growing even as fewer people are going to college.
Online degrees are also concentrated among a handful of nonprofit universities. Just three — Western Governors University, Liberty University and Southern New Hampshire University — enroll about a third of all online students at private, nonprofit institutions.
overwhelming research evidence that community college students aren’t faring well in online classes
Another 2017 study of students at a for-profit university which offers both in-person and online classes found that students who took an online class not only got lower grades in that class but also in future classes. Online students were more likely to drop out of college altogether than similar students who attended in-person classes.
There are much stronger results for courses that combine supplemental materials online with traditional, face-to-face instruction. But the authors do not consider this hybrid instruction to be “online” learning.
Smartphones also provide an easy way for teachers to “inspire students to positively contribute to and responsibly participate in the digital world,” as espoused by the ISTE Standards for Educators.
research shows that when students are engaged in their learning — and they’re almost always engaged with their phones when given a choice — they are less likely to succumb to distractions.

Gartner predicts that nearly 38 percent of companies will stop providing devices to workers by 2017 — but 20 percent of those BYOD programs will fail because of overly restrictive mobile device management measures. So how can IT pros devise a BYOD strategy that stays afloat? Here are six guidelines to accommodate legitimate IT concerns without sinking a policy’s odds of success:
Look to Existing Policies
Before creating a BYOD policy, take a look at existing HR and legal procedures. Many email, VPN, and remote access security policies can be applied to mobile devices, as well.
Provide Training and Education
Employees are using personal devices at work, whether the company realizes it or not. But that doesn’t mean they are using them correctly. Employees often use file-sharing and other tools of their choosing without IT’s knowledge, which could put sensitive corporate data at risk. Use a BYOD policy to trainemployees how to correctly use their applications
Specify Devices
BYOD isn’t limited to smartphones. According to Gartner, a “new norm” is emerging in which employees manage up to four or five devices at work.
Enforce Passwords and Encryption
passwords aren’t foolprool. Data encryption is an additional security measure
A smart BYOD policy doesn’t mean IT is off the hook. Rather, successful policies rely on IT and employees sharing security obligations.
Set Ownership Expectations
Employees often fail to realize that all data on their devices is discoverable, regardless of whether the device is personal or company-owned. The question of who owns what is still a legal gray area, though companies increasingly take the liberty to remote wipe employees’ personal devices once they leave their job. Avoid the guessing game with a clear exit strategy.
Teachers are turning to the practice as a simple way to restore calm to the classroom, help students find some quiet space, and build self-regulation skills. Some teachers say their personal mindfulness practicehas helped them respond more calmly to students and helps them keep perspective.
“This isn’t about calming down,” said Sam Himelstein, a clinical psychologist, trainer and author who has spent most of his career working with incarcerated youth. “Calming down is great and it is a skill that youth can get better at. But if we’re talking about mindfulness, at its core, we are just talking about being present with whatever it is.”
Larry Rosenberg the dog-mind versus the lion-mind.
Reacting with the mind of a lion allows a person to say, “I’m angry right now,” and that little bit of metacognitive space between the person and the thought allows them to choose how to respond.
TRAUMA SENSITIVE MINDFULNESS
Students don’t take the activity seriously
Students are triggered by silence because it feels like a storm is brewing, so they don’t want to be quiet
Students feel too many requests are made of them without the requisite trust being built up
Students exhibit avoidance behavior
Guidelines for teachers using mindfulness:
Don’t force it
Don’t focus on the logistics like sitting with eyes closed
Somatic awareness, like counting breaths, could be a good place to start. “There’s different types of awareness. Sometimes we’re really aware of what’s going on in the mind and sometimes we’re more aware of what’s going on in the body,” Himelstein said.
Think about the child’s window of tolerance and whether he is already triggered or not. “It’s good to strike when the iron is cold in a lot of these cases,” Himelstein said.
Build relationships
SELF CARE
Cultivating a trauma-informed classroom is much harder when educators themselves are burnt out. Building relationships, not reacting defensively to student behavior and taking time to listen to students can feel nearly impossible if the adult is barely making it through the day.
several categories of self-care, according to Himelstein:
Regular cultivation of relaxation response (3Rs): things like watching TV, going into nature, getting a massage.
Effortful training: These are things like more sustained meditation or exercise where the payoff comes over a longer time period.
Creativity: something that gives purpose and adds vibrancy to life. Writing, reading, painting or other passions are examples.
Advocacy: everything from learning to say “No” (set boundaries), to working at a higher level to impact policy or structural change.
