South Africa: JSE Rally – It’s Prudent to Factor in What Could Spoil the Party

south africa jse rally its prudent to factor in what could spoil the party
aa logo rgba no text square

The JSE continues to outpace its developed market peers in a rally that has – including a few pullbacks – added 77% to the value of the exchange since last March’s market meltdown. However, with most of the good news driving the recovery emanating from beyond South Africa’s shores, can it continue?

Optimism over strong recoveries in developed market economies, including the US and most of Europe, as vaccine programmes are rolled out, has helped fuel strong equity market performances this year. So, too, has the massive stimulus pumped into economies by central banks, including the Federal Reserve.

While the JSE’s gains seem to belie local economic prospects and the slow pace of vaccinations, it is benefiting, to the full, from the global factors.

The exchange’s broad-market All Share Index rallied more than 3% on Friday, and continued rising on Sunday, taking its year-to-date gain to over 13%. The blue-chip Top 40 Index, which includes the exchange’s most valuable shares, shows a similar gain.

As has been the case for most of the year, resource stocks have led the charge, with the JSE’s Resources 10 Index soaring 5%.

Bipartisan Legislation Would Allow E-Rate Funding for School Bus Wi-Fi

bipartisan legislation would allow e rate funding for school bus wi fi
MB Ben Ray Lujan BLOG
Ben Ray Lujan

A bill recently introduced in the U.S. Congress would make make E-Rate money available to support Wi-Fi on school buses, the latest of several recent recent efforts to expand student internet connectivity outside school hours.

Sens. Ben Ray Lujan, D-N.M., and Lindsey Graham, R-S.C., have introduced the legislation, which would require the Federal Communications Commission to issue regulations to make Wi-Fi access on school buses eligible for support under the E-Rate program no later than 180 days after enactment. Under the bill, schools would be reimbursed for equipping buses with Wi-Fi.

The E-Rate program is funded at $4 billion annually, and allows schools to receive reimbursement for certain internet services provided on campus.

If policymakers provide more financial support for off-campus wireless services, it could increase the ability of students to make use of companies’ ed-tech tools, apps, and platforms, including on long bus rides where students have access to laptops and other devices, if this bill gets enacted.

The bill is aimed, in part, at promoting digital equity for rural and tribal communities in states like New Mexico, according to Lujan’s office.

Approximately one-quarter of New Mexico’s over 350,000 students don’t have affordable internet, according to a statement by the New Mexico Homework Gap Team, which describes itself as an ad hoc group of professionals who support narrowing the digital divide for K-12 students in the state.

A December study by the Alliance for Excellent Education estimated that almost 17 million students nationwide lack home internet access to complete school assignments.

“For rural and tribal students who travel hours to and from school, these commutes can be valuable time accessing the internet, completing assignments, and conducting research,” Lujan said in a statement. “Empowering our schools to equip buses with Wi-Fi is an opportunity to uplift our students, tackle the homework gap, and help alleviate the financial strain that too many families are experiencing at home.”

If passed, the legislation would give schools more flexibility in terms of figuring out how they can best use ed tech to promote equity, said Amina Fazlullah, equity policy director for Common Sense Media, a nonprofit dedicated to promoting safe and effective technology use for children.

“Every community has different layers of barriers to equitable access to education related to technology,” she said in an interview. “Having that flexibility ultimately in the E-Rate program will be incredibly useful for schools where students have long commutes.”

But Fazlullah suggested that the ed-tech funding expansion outlined in the Lujan-Graham bill shouldn’t substitute for other potential federal initiatives to support costs for students’ home connectivity.

It remains to be seen whether the FCC will act decisively on some lawmakers’ and education advocates’ calls for a long-term, dedicated funding source to support students’ home connectivity.

The COVID-19 stimulus package approved earlier this month allocated $7 billion to the FCC for the creation of what is being called the “Emergency Connectivity Fund,” separate from E-Rate, to pay for high-speed internet and devices used off campus.

The commission also recently announced plans for a policy that, among many other things, would allow school districts to apply for reimbursement for costs they have paid for students and teachers to access broadband at home.

FCC Acting Chairwoman Jessica Rosenworcel, in an interview with Education Week this month, said the agency remains in the “process of evaluating how we can update the current E-Rate program to meet the moment students and families find themselves in.” She spoke after the agency in February issued a request for public comments on whether E-Rate funds could be used to support remote learning during the pandemic.

In 2018, then a U.S. congressman, Lujan became familiar with how Wi-Fi operates on a school bus when he attended a “Rolling Study Halls” event. Hosted by Santa Fe Schools and funded by Google, the event took a Wi Fi-equipped bus to a Native American pueblo in New Mexico, Tom Ryan, chief information and strategy officer for the district, noted in an email.

In addition to Santa Fe, the Albuquerque district is one other school system that has outfitted school buses with mobile Wi-Fi units, installing hot spots on 80 buses across the area as of October.

Rep. Peter Welch, D-Vt., has introduced legislation similar to the Lujan-Graham bill in the House.

The legislation has picked up endorsements from the National Education Association, Competitive Carriers Association, Free Press, Public Knowledge, School Superintendents Association, Association of Educational Service Agencies, Association of Latino Administrators and Superintendents, National Rural Education Association, National Rural Education Advocacy Consortium, and the State Educational Technology Directors Association.

[on behalf of Nirmal Patel]

Call for Papers: Process Analysis in Education Workshop @ EDM2021

*We are inviting short papers for this workshop! Please read the topics and
submission guidelines below or read them on the website!*

Workshop website:


We are happy to announce a Process Analysis in Education workshop at the
2021 Educational Data Mining Conference in Paris, France. We welcome all
researchers who are interested in discovering the learning and teaching
processes from educational data in order to advance our understanding of
human learning and build more effective educational programs and technology.

This workshop aims to bring together researchers using different methods to
analyze process aspects of educational data. The ubiquity of temporal
student data has enabled us to apply many different process analysis
methods to uncover educational processes hidden within the data. The choice
of the process analysis method often depends on the research questions and
the form of the data, and they vary widely among researchers. Through this
workshop, we are creating an event where researchers can share the process
analysis methods they use, and discover what other methods are being used
in the community. We believe that this sharing of knowledge will empower
our community to discover novel insights from educational data.


We are inviting short papers (up to 6 pages + references) that are related
to the topics outlined below or on a topic that is aligned with the overall
objective of the workshop.

*Discovery and Analysis Methods*

   – What methods are available to mine different representations of
   educational processes from sequential/temporal data?
   – How can we compare process representations of different individuals?
   – In what contexts some process representations work better than others?
   – How can we analyze process data with a high variance?
   – How can we visualize the learning and teaching processes?

*Insights and Applications*

   – How can we get insights about learning and teaching in the real world
   from process data?
   – How can we use process insights from data to inform real-world
   educational interventions?
   – How can we apply process models in learning engineering contexts to
   build applications like recommender systems and/or various types of
   adaptive learning systems?

*Theory and Experimentation*

   – How can we validate the discovered process models using psychology and
   cognitive science theory?

How to Hide Your Caller ID? [2021 Guide]

how to hide your caller id 2021 guide
efani logo 1

Caller ID or Caller identification is a phone service which transmits a caller’s number to the called party’s telephone equipment while the call is being set up. 

It is available in analogue and digital telephone systems, including the ( VoIP ). In a service known as the Calling Name Presentation (CNAM), the ID service may involve the transmission of a name.

Despite its explanation, ID display is one of the prime issues for many users. Let’s look into how to block your caller ID on different mediums.


iOSAndroidDesktop Devices
1. Launch the “Voice” app.
2. Tap Menu and then Settings in the top left corner.
3. Turn Anonymous Caller ID “On” in the Calls section.
Switch Anonymous Caller ID Off if you want people to see your phone number when you call them.
When you conceal your caller ID on one device, it is also hidden on all other devices connected to your Voice account.
1. Go to the Voice app on your device.
2. Tap on Menu (you can find it at the top left corner)
3. Subsequently click on Settings.
4. Search the subheading under settings as calls, you will see an option of Anonymous Caller ID. Toggle it on
In another scenario, if you’re willing to display your digits so people can see it, you need to simply toggle off the Anonymous Caller ID.
1. Go to the on your desktop.
2. Tap “Settings” in the upper right corner.
3. Tap Calls on the left.
4. Turn on Anonymous Caller ID
Switch the Anonymous Caller ID Off if you want people to see your phone number when you call them.

The Golden Prefix

How can you hide your caller identification on a single device while this click blocks your caller Identification on integrated devices with your Voice account?

You can also hide your caller identification for specific individuals. You can also block your Caller Identification if you do not wish it to be displayed in front of particular individuals (temporarily).

  • Go to Voice Application
  • Tap on the Calls tab.
  • Enter the prefix for blocking your caller ID before calling the phone number.

This prefix is determined by the region or country from which your Voice number originates. If your Voice number is from the United States, for example, your code is *67 (before entering the number).

Reminder: Regardless of the number you’re calling, you always use the same prefix.

After inserting the prefix, dial the phone number.
Your phone number will not be visible to the person you are calling.

Google Voice

Google Voice allows you to create a new phone number and use it to make free voice calls, emails, and audio messages. To get started, all you’ll need is a Google account.

Unlike the other choices, Google Voice does not require a monthly fee. It makes use of your current phone minutes/data plans, but the number displayed is your Google Voice number.


TrueCaller is the most popular caller identification and spam filtering app trusted by the audience worldwide. You’re tired of people calling you to sell you different schemes and offers? You can block them with the TrueCaller. When you receive a call from a number that has been blocked by too many users, TrueCaller will display a red contact card to alert you about fraudsters.

SURPRISE: Take command of your landline as well.

Disable Caller Identification Block (*67) by dialling *82.

Disable Anonymous Call Rejection (*77) by dialling *87.

(I heard you say awesome, so TIA)
