Are You Part Neanderthal? Check Your Hair and Teeth


Are you part Neanderthal? Of course we would never consider ourselves to be part brute but that is what our DNA is telling us. A majority of us have a few percentage points of Neanderthal DNA within our bodies. Ironically those things that make us look attractive like hair and teeth are more closely tied to our ancient ancestors. 

Studies in the journal Nature and Science help us think about human development from the beginning of time until now. It is believed the Neanderthal was a northern creature while humans came from Africa. Somewhere along the path they interbred and the Neanderthal died off. Apparently, the males were not so great at breeding when mixed. 

Human development appears to be on a continuum from the past to some marked point in the future. Each child creates a new genetic destiny based upon a historical past and develops something unique. As the environment changes, humans change with it to ensure they able to survive and pass on their genetic code. 

Neanderthals died off due to lack of communication skills and environmental adjustments. Modern language appears to be one of the most defining and beneficial aspects of social development. Where Neanderthals could run around in packs of a half dozen humans can now travel in the thousands.

Saving Gifted Butterflies with Service Learning


Service learning can help high school and college students raise their grades and connect to a wider world. A paper by Bruce-Davis and Chancy (2012) discuss to a greater degree how service learning improves upon the platform for regular students but can help gifted students reach new heights. Education isn’t always stuffed in some dusty book and can include practical application of interests. Once engaged, gifted students can engage for years until breakthroughs are created.

Gifted learners are often underachievers. Their brains work at a capacity where standard curriculum bores them right out of school and directly into the school of life. This is why history is full of the genius drop out. Adding on top of this, teacher misperceptions, rigid classroom structures, and improper social relations, the school system can seem more like a prison system. 

Gifted learners underachieve because there is little to achieve for. If their classmates are focused on the latest He Man toy or newest Barbie member over the next Mad Science edition there is going to be dissonance. As these children grow into adolescents the focus on rigid social adherence and outward perception can also take their toll. Teachers may encourage these social patterns as “healthy development”. 

The problem is that gifted learners are asynchronous and develop at different stages and times. Service learning allows gifted students to throw themselves into something that interests them. Strong teachers can integrate normal class work into some service activity the gifted student finds interesting. The options are unending and can range from poetry to feeding the poor. 

Other researchers have found that service learning allows for practical application of knowledge and can be beneficial in raising motivation and grades. Service learning can be even more profound for inner city students that desire to find purpose and meaning in school while connecting with a wider community. The percentage of college readiness and graduation rates increase if high schools use these methods. 

If we look at a definition of giftedness from Renzulli and Reis (1997) you will find that service learning fits within task commitment, abilities, and creativity. “Gifted behavior consists of behaviors that reflect an interaction among three basic clusters of human traits—above average ability, high levels of task commitment, and high levels of creativity. Individuals capable of developing gifted behaviors are those possessing or capable of developing this composite set of traits and applying them to any potentially valuable area of human performance. (p. 8)” Some gifted individuals can engage in these activities for years, decades, or lifetimes. 

Service learning can help most students gain a bigger picture of their life’s responsibilities beyond their own needs. For gifted individuals, service learning can help them find practical application and motivation for their existing skills. For those who are previously undiagnosed, service learning methods affords opportunities to do something interesting and expose their greater abilities beyond rote textbook learning. High grades often measure intelligence but fail to measure higher abilities and capacities beyond sequential learning. Who wouldn’t be enthusiastic about saving butterflies, reducing child hunger, or creating better methodologies?

Predicting Purchasing Behavior Patterns in Stationary Markets


Predicting patterns of consumer behavior can be difficult. To date no one has developed a perfect model as each has its own particular short-comings. The Dirichlet model is well-established that both describes and predicts purchasing behavior patterns in stationary markets. The researchers McCabe, et. al. (2012) focuses on the success of the model for companies trying to gain market share. 

It should be first understood that all purchasing is based in habits of purchase. Customers follow certain patterns based upon how they associate the information among competing brands. Marketing nudges individuals to make one choice over another to expand their repertoire of purchasing behaviors. Strong marketing creates memories that become associated with products and services. 

Structural changes in behavior can occur when changes force choices beyond day-to-day decisions. Even though industrial marketing and purchasing is long-term and stable it can change. These changes usually are a result of introduction and reminding of products during purchasing cycles. For consumers, original patterns of purchasing can return right after promotion and therefore be short-lived changes. 

The authors used a collaborative procurement to understand the purchasing power of an organization that spends 20 billion pounds on third-party products. They observed purchasing behavior over a 12 week period to determine penetration, frequency and share of category by particular suppliers.  They found some switching patterns among suppliers in term of amount and quantity of purchases. 

Supplier B increased market share at the company over Supplier A. Even though there were no new products or services offered that would attract purchasers it was found that Supplier B invested in its regional sales force prior to the change. The Dirichlet model did well with predicting market changes before, during, and after marketing campaigns. Even when it was not accurate it worked as a benchmarking tool. 

Comment: Marketing is a process of raising a company’s voice within a particular market. The more different the culture of the target market to that of the parent the more difficult it is to find the right voice. When done properly consumers will have more memories of the product/service which raises their chances of making a purchase. Some advertisements can create motivation based upon the individual needs of the consumer. Purchasing managers are not immune to the same needs, motivations, and memory processes as general consumers. They only become more sophisticated in how they process the information and make decisions.

Book Review: Darwin among the Machines by George Dyson


Darwin among the Machines by George Dyson delves into the evolution of global intelligences. Even though it does offer some scientific tid bits it is primarily a philosophical book that explores the growing field of artificial intelligence. Darwin discovered organisms working under various laws to Turning’s simple thinking machine.  The Internet provides a global platform for creating global intelligence where constant streaming of information can be incorporated into brighter minds and machines. The process of development is based in principles found by Darwin and others. 

His work is a historical understanding of intelligence that starts with Thomas Hobbes (1588-1679) and moves all the way into modern theory. Thomas Hobbes wrote in the book Leviathan “Nature (the Art whereby God hath made and governes the world) is by the Art of man, as in many other things, so in this also imitated, that it can make an Artificial animal”.  In other words, the laws of nature can be put within a theoretical understanding and then into machinery (automata). 

His work then moves into John von Neumann’s (1903-1957) who discusses the connections between neural activity and Game Theory.  Intelligent machines are able to handle a flow of information and convert that information into logic. John von Neumann’s discovery of replication in complex creatures was a precursor for DNA and modern neurobiology. 

He stated, “To understand high-complication automata and, in particular, the central nervous system... this process logic will have to undergo a pseudomorphosis to neurology to a much greater extent than the reverse.” The thinking machine will need to change and replicate itself in much the same way as biological beings. That change and process of information comes from the central processing system (i.e. central nervous system). 

The author argues that the whole world has collective intelligence above and beyond the intelligence of the individual parts. Machines may someday be able to process that intelligence but they are projections of the human mind and therefore have limitations. The human race will continue to develop and reach higher heights in understanding. The risks humans face is that they may disintegrate and collapse like other species. It is not sure if machines have the same risks. 

The book is relevant for modern day changes in robotics and artificially intelligence. If you follow the technology industry you may be surprised by announcements related to robotic development, artificial intelligence, micro-manufacturing, and acquisitions within particular companies. This development has been growing for many generations and is often marked by misunderstanding, myth, lore and fear. There will sure be greater scientific understandings of human intelligence as developers seek to mimic and understand these functions for other uses.
