Pre-Historic Art

The earliest figurine yet discovered come from between 500,000 and 300,000 BC, during the Middle Acheulean period. Discovered in Morocco, it is about 6 centimeters long. Evidence suggests that this Moroccan piece may have been created by natural geological processes with a minimum of human tool-work, but the piece bears evidence of having been painted; "a greasy substance" on the stone's surface has been shown to contain iron and manganese and indicates that it was decorated by someone and used as a figurine, regardless of how it may have been formed.

Discoveries in Blombos cave, situated in South Africa, have totally changed the history of art. Stones were discovered that were decorated with complex red arrays, showing that early Homo Sapiens Sapiens were capable of abstraction and production of art. These impressive works date back from 70,000 years ago i.e. more than 50,000 years compared to Lascaux in France.

Venus of WillendorfThe earliest known European art is from the upper palaeolithic period and includes both cave painting, such as the famous paintings at Lascaux, and portable art, such as animal carvings and so-called Venus figurines like the Venus of Willendorf.

There are some speculations that only Homo sapiens is capable of artistic expression. However, Homo erectus had long before produced seemingly aimless patterns on artifacts such as is those found at Bilzingsleben in Thuringia, and these might be understood as a precursor to art, as well as to reveal some intent of the artificer to decorate, to fashion beyond practical necessity.

The symmetry and attention given to the shape of a tool has led authors to see middle palaeolithic hand axes and especially laurel points as artistic expressions as well. The Venus of Berekhat Ram (Israel) and its counterpart in Morocco, the Venus of Tan-Tan, from 800,000 and 220,000 BC, may be the earliest attempts to recreate the human form. A recent find, the Mask of La Roche-Cotard in France, now suggests that Neanderthal humans may have developed a sophisticated and more complicated artistic tradition.

Drawing of bracelets from Mousterian period.Later findings from terrains of Ukraine (Mizyn archeological site) dated from Mousterian epoch of Paleolithic are Mammoth ivory bracelets with carved meander ornaments.

Mesolithic

The Mesolithic period has some examples of portable art, like painted pebbles (Azilien) from Birseck, Eremitage in Switzerland, and in some areas, like the Spanish Levant, stylized rock art. Patterns on utilitarian objects, like the paddles from Tybrind Vig, Denmark, are known as well.

Decaying K-12 School Communications Infrastructures Turn to New High Capacity Wireless Networks for Salvation

Because of declining tax bases and increased needs for academic accountability and performance, the days of traditional K through 12 "classroom only" learning are numbered. They are rapidly being replaced by a truly multi-mode combination of self-instruction, specialized out of classroom coaching (often by off-site, higher grade peer tutors), parental monitoring and involvement and specialized "distance learning" curriculum.

All of these faster, more individualized and more efficient teaching tools have one thing in common: They will gobble up connectivity resources, and require delivery of information in places that may have yet to embrace the new format's high speed, high bandwidth demands, whose existing "legacy" systems will be outpaced by them.

Help is being sought in ways that in effect leave behind the costly purchase, rental or construction of traditional "wired" networks in distributed school systems, for a one time, less expensive purchase of a new class of high speed, high dependability wireless local area networks.

For example, a Northern Indiana school system recently eschewed a traditional "land based" leased network and instead installed a licensed wireless gigabit Ethernet (GigE) "point to point" managed services solution. The new system permitted the school system to upgrade capabilities, allowed room for growth, ensured integrity of the system through the use of licensed spectrum, and transferred costs from a model of total ownership to one of purchasing services resulting in tremendous savings. And speed? Well the system transfers data as fast as many traditional wired local area networks within buildings at 100 MB transfer rates. It has allowed them to save on their traditional voice communication costs as well as data, enabling new lower voice over IP (VoIP) technologies that use the same data networks.

While a seemingly technical solution, the fact is that this school system is joining others in looking for new technologies to help them with old problems. Numbers from The Center on Budget and Policy Priorities reports that at least 22 states are cutting K-12 and early education. Already, Arizona, Florida, and South Carolina have each cut school aid by an estimated $95 or more per pupil. Rhode Island is eliminating early education funding for 550 children, and Massachusetts is reducing funding for a number of early care programs. And the trend is not stopping at primary education: At least 30 states have implemented cuts to public colleges and universities, resulting in cuts in faculty and staff and tuition increases of 4 percent to 15 percent. Students in Rhode Island and New York are facing mid-year tuition hikes.

So in the end, the question will likely not be whether to use technology to shape education's future, but how. "Cutting the wire' will likely be one of those strategies that will be needed to keep our most important asset, our innovation, alive.

Choose Your Online Marketing Provider Wisely

Quick Tip: business owners hire local SEO companies to get their website ranked higher in the search engines. For higher search engine visibility hire a local SEO service provider.

Attempt to look for an SEO or Search Engine Optimization company on the internet and you'll see a confusing list of technical services and offerings. Searching in your local area on Google for SEO services can produce a more focused list of results such as "Northern VA SEO Services" however finding and interviewing are two totally different objectives.

Finding an SEO company takes planning.

If you're looking to have SEO services performed on your website, beware of the companies that offer to submit your site to search engines. Submitting your website to search engines is a bad SEO practice and can even harm your ranking results. It's much better to have the search engines find your website naturally rather than submitting it.

Search engine Directory submissions can be of benefit, which are different from direct search engine submissions. Your best option for online SEO success is to have Google find your website naturally. Keep that in mind when asking an SEO specialist if they will be submitting your site to search engines OR directories. Directory submissions are a good practice, search engine submissions are not.

It's a good idea to ask your SEO specialist if they will be creating a site map. Sitemaps are a good practice however the new Google standard is the .xml format. If your SEO specialist does not talk about .xml as a sitemap format then you should move on and interview others.

Ask them what tools they use to perform keyword research. Google provides a free keyword tool and there are many others however if your SEO specialist asks you for a keyword list about your business and goes not further then look for a specialist that uses a diverse mix of keyword tools and research techniques.

SEO best practices call for building links to your website, ask what link building techniques they use. Article marketing is probably the number one technique. Watch out for link building plans that grow your links too quickly, one thousand or less per month is a good practice.

Also beware that your website is only as good as it's ability to convert your best visitor to a customer. You can rank for all of the most popular terms related to your business however if your website doesn't convert the visitor to a customer you may not get the sale. Don't rely only on search engine optimization for success, continue to write effective sales copy for your site on a regular basis and test what works.

Also, to be sure that your chosen SEO specialist has done this type of work in the past ask them to contact a current or past client. Speaking with a past client can help you determine the type of work and service you'll be getting.
