Algorithm Tool Created to /wean Out Predators In Chat Rooms

Snapshotfishnet6

An algorithm tool developed by Purdue Polytechnic Institute faculty will help law enforcement filter out and focus on predators most likely to set up face-to-face meetings with under age victims.

The Chat Analysis Triage Tool (CATT) was presented last week by principal investigator Kathryn Seigfried-Spellar, assistant professor of computer and information technology, at the International Association of Law Enforcement Intelligence Analysts Conference in Anaheim, California.

CATT allows the officers to work through the volume of solicitations and use algorithms to examine the word usage and conversation patterns by a suspect. Seigfried-Spellar said data was taken from online conversations provided voluntarily by law enforcement around the country.

The project started as a result of a partnership with Ventura County Sheriff’s Department in California.

Seigfried-Spellar said the research discovered tactics like self-disclosure is used early in a predator’s talks with a potential victim.

Seigfried-Spellar worked in developing CATT with two co-principal investigators, associate professor Julia Taylor Rayz, who specializes in machine learning and natural language processing, and computer and information technology department head Marcus Rogers, who has an extensive background in digital forensics tool development.

CATT algorithms examine only the conversation factors and do not take the gender of either suspect or victim into consideration, at this time.

The project began with initial research done by Seigfried-Spellar and former Purdue professor Ming Ming Chiu. The exploratory study examined more than 4,300 messages in 107 online chat sessions involving arrested sex offenders, identifying different trends in word usage and self-disclosure by fantasy and contact sex offenders using statistical discourse analysis.

The trends determined through this research formed the basis for CATT. The research, “Detecting Contact vs. Fantasy Online Sexual Offenders in Chats with Minors: Statistical Discourse Analysis of Self-Disclosure and Emotion Words,” has been accepted and will be published in the journal “Child Abuse and Neglect.”

Initial plans are to turn the tool over to several law enforcement departments for a test run. Seigfried-Spellar said CATT could be handling data from active cases as early as the end of the year.

The Future Of Jobs & Skills

Education and training systems, having remained mostly static and underinvested in for decades, are largely inadequate for these new labor markets. Additionally, a prevailing gender bias is introducing further inefficiency and inequality. The Economic forum says we must rethink the way talent is developed and deployed in the world. This will require breaking down old silos between education systems and labor markets, more agile approaches to regulation, new forms of public-private collaboration, and new norms and values.

The World Economic Forum’s System Initiative on Shaping the Future of Education, Gender and Work seeks to ensure that talent is developed and deployed for maximum benefit to the economy and society. How, by mobilizing leaders from business, government, civil society and others through new insights, common agendas, and collaborative action. The objective: build an ecosystem of leaders by bringing together a community of business, policy-makers, civil society and other leaders; 

 

Nursery Groups In London Reveal Gender Gap in Pay

Snapswhiteskirt & blouse3_001

Nursery groups with more than 250 employees have reported on their gender pay gaps, with women ahead in some companies, but men still paid more in others despite the female-dominated nature of the early years sector.

New gender pay reporting legislation has required large companies to reveal the extent of pay differences between men and women for the first time. Nationwide, three-quarters of companies have been shown to pay men more than women, with the average pay gap 18.4 per cent in favour of men, but the early years picture is different.

Mr Trump has suggested arming a significant portion of the educator workforce – between 10 and 40 per cent of teachers – using federal resources.

 United States educators have expressed frustration at a proposal by US President Donald Trump for teachers to take up arms to defend their classrooms against school shooters.

Many teachers expressed concerns about scenarios in which they could face shooters on a hectic campus – or even, potentially, draw a gun to confront an armed and dangerous student. 

Mr Trump suggested arming a significant portion of the educator workforce – between 10 and 40 per cent of teachers – using federal resources. He said military veterans who teach would be prime candidates for these roles. 

Many schools already hire police officers or armed guards to patrol campuses with the help of federal money. About 57 per cent of public schools in the 2015/2016 school year had security staff on campus at least once a week and nearly 43 per cent were patrolled by armed law enforcement officers, according to federal data.

 Dr Dewey Cornell, a University of Virginia professor who studies school safety said, “The proposal to arm teachers might be emotionally appealing after a school shooting, but it is not practical or realistic,” said 

“We should place more emphasis on preventing shootings than preparing for shootings. Prevention must start long before a gunman shows up at school. Instead of more guards, we need more counselors.”

 

According To Statistics From U.S. Department of Education, 32 Million Adults In The U.S. Can’t Read.

Reports reveal that the rate of low literacy in the United States is higher than some of the third world countries and costs the healthcare industry over $70 million every year.

In 2013, Washington, D.C. was ranked the most literate American city for the third year in a row, with Seattle and Minneapolis close behind.

Long Beach, CA was ranked the country’s most illiterate city, followed by Mesa, AZ, and Aurora, CO.

What is the literacy rate in the world?
The global literacy rate for all males is 90.0% and the rate for all females is 82.7%. The rate varies throughout the world with developed nations having a rate of 99.2%(2013); Oceania having 71.3%; South and West Asia having 70.2% (2015) and sub-Saharan Africa at 64.0% (2015).
 
Russia: The country with the highest literacy rate is Russia with almost 53% of the population has tertiary education. It is estimated that 95% of adults in Russia have higher secondary education and the country spends some 4.9% of GDP on education.

Trends In eLearning

6 Emerging Technology Trends Changing eLearning

Virtual Reality (VR)

VR can transmit students to the farthest corners of the universe in just a blink of an eye and surround them with an engaging and deeply educational environment. Students will no longer be stuck with pages upon pages of boring text, bullet points, and illustrations, but they will have a chance to actually go through the experience and get the most out of it instead.

Augmented Reality (AR)

Augmented Reality is a technology that superimposes a computer-generated image on a user’s view of the real world, thus providing a composite view. This, also, includes real-world sensory input like video, graphics, or sound [2].

When it comes to eLearning, Augmented Reality can make the learning process more interesting and easier to grasp. For instance, if you were an online instructor and your target subject was astronomy, you could offer your students a virtual tour of Mars without asking anyone to leave their home.

Artificial Intelligence (AI)

Artificial Intelligence is referred to the intelligence displayed by machines, as opposed to natural intelligence displayed by humans and animals [3]. It is revolutionizing the whole eLearning experience due to the many advantages it has to offer. AI can help highlight areas that require improvement and assist students in focusing on areas where they are lagging.

Big Data

If an employee is interacting with a training module based around company policies, their progress, social sharing, assessment results, and another relevant date that is being generated throughout the eLearning course is referred to as “big data”.

Big Data allows eLearning experts to understand how the users are digesting the information and which learning aspects appeal the most to them. In addition to that, it allows them to pinpoint learning interactions that should be fine-tuned within the eLearning module or course.

Wearable Devices

Wearable devices also referred to as wearables, are smart electronic devices that can be worn on the body as accessories or implants

Machine Learning

Machine Learning is a field of computer science that gives computers the capacity to learn without being directly programmed.
