We can design a attractive survey in just a few minutes.One of the great benefits of Vovici online survey software is that it collects and analyzes our results automatically, which takes a lot of the busy work out of our research. We can easily create graphs, tables, cross tabs, subgroups and drill downs for your results. We can also very easily download your raw data into SPSS or Excel.
360 Evaluations
A 360 evaluation is a technique used to gather information about an individual from all around them. This can be done through this online survey easily.The same survey is distributed to people with different relations to the individual in an organization. For example, the feedback would come from subordinates, peers, and managers in the organizational hierarchy. It is also common to obtain a self-assessment from the individual. It is called a 360 Evaluation because the feedback comes from all-around the individual.
This is helpful because some individuals can be two-faced, and act and behave on one way to those above them, and completely different to those underneath them. With a 360 Evaluation, you can determine what different levels feel about the individual and get a better perspective of the whole picture. Vovici surveys are great for doing 360-Evaluations and provide great reporting tools so you can easily understand what the feedback is saying.

Introduction – What Is SEO
1)Search Engine Optimization (SEO) is often considered the more technical part of Web marketing.
2)SEO does help in the promotion of sites and at the same time it requires some technical knowledge – at least familiarity with basic HTML.
3)Generally, SEO can be defined as the activity of optimizing Web pages or whole sites in order to make them more search engine-friendly, thus getting higher positions in search results.
4)SEO helps to increase the traffic to site.
5)if you really want to be at the top, you need to pay special attention to SEO and devote significant amounts of time and effort to it. Even if you plan to do some basic SEO, it is essential that you understand how search engines work and which items are most important in SEO.
How Search Engines Work
The first basic truth you need to learn about SEO is that search engines are not humans. While this might be obvious for everybody, the differences between how humans and search engines view web pages aren't. Unlike humans, search engines are text-driven. Although technology advances rapidly, search engines are far from intelligent creatures that can feel the beauty of a cool design or enjoy the sounds and movement in movies. Instead, search engines crawl the Web, looking at particular site items (mainly text) to get an idea what a site is about. This brief explanation is not the most precise because as we will see next, search engines perform several activities in order to deliver search results – crawling, indexing, processing, calculating relevancy, and retrieving.
First, search engines crawl the Web to see what is there. This task is performed by e piece of software, called a crawler or a spider (or Googlebot, as is the case with Google). Spiders follow links from one page to another and index everything they find on their way. Having in mind the number of pages on the Web (over 20 billion), it is impossible for a spider to visit a site daily just to see if a new page has appeared or if an existing page has been modified. Sometimes crawlers will not visit your site for a month or two, so during this time your SEO efforts will not be rewarded. But there is nothing you can do about it, so just keep quiet.
What you can do is to check what a crawler sees from your site. As already mentioned, crawlers are not humans and they do not see images, Flash movies, JavaScript, frames, password-protected pages and directories, so if you have tons of these on your site, you'd better run the Spider Simulator below to see if these goodies are viewable by the spider. If they are not viewable, they will not be spidered, not indexed, not processed, etc. - in a word they will be non-existent for search engines.
After a page is crawled, the next step is to index its content. The indexed page is stored in a giant database, from where it can later be retrieved. Essentially, the process of indexing is identifying the words and expressions that best describe the page and assigning the page to particular keywords. For a human it will not be possible to process such amounts of information but generally search engines deal just fine with this task. Sometimes they might not get the meaning of a page right but if you help them by optimizing it, it will be easier for them to classify your pages correctly and for you – to get higher rankings.
When a search request comes, the search engine processes it – i.e. it compares the search string in the search request with the indexed pages in the database. Since it is likely that more than one pages (practically it is millions of pages) contains the search string, the search engine starts calculating the relevancy of each of the pages in its index to the search string.
There are various algorithms to calculate relevancy. Each of these algorithms has different relative weights for common factors like keyword density, links, or metatags. That is why different search engines give different search results pages for the same search string. What is more, it is a known fact that all major search engines, like Yahoo!, Google, MSN, etc. periodically change their algorithms and if you want to keep at the top, you also need to adapt your pages to the latest changes. This is one reason (the other is your competitors) to devote permanent efforts to SEO, if you'd like to be at the top.
The last step in search engines' activity is retrieving the results. Basically, it is nothing more than simply displaying them in the browser – i.e. the endless pages of search results that are sorted from the most relevant to the least relevant sites.

Alternatives to CAPTCHA
CAPTCHA stands for "Completely Automated Public Turing Test to Tell Computers and Humans Apart".CAPTCHA is a set of methods commonly used to block automated account registration and spamming.It refers to a verification scheme used by sites to ensure that web content is accessed only by persons.
CAPTCHA suffers from many problems.
First, it is often very unethical - it unnecessarily discriminates against blind and otherwise visually impaired people.
Secondly, CAPTCHA is not always very good at keeping spam away because computer software already can, generally speaking, recognize letters as well as humans, and computer itself has plenty of advantages over human. Often you see a misguided attemt at making CAPTCHA harder - for example, low text-to-background contrast or bad color combination does nothing to stop computer, but makes it harder to read for human. Often, human don't know how many letters should be there, and random lines may look like yet another distorted letter; whereas captcha-breaking software would know how many letters are supposed to be in this captcha, and when detecting more letters, can eliminate the least likely.
Some letters in common fonts differ too little to be reliably recognized by human when distorted (such as 0,O ; I,l,i,!,j ; vv,w and so on). Humans recognize heavily distorted letters in handwriting based on the context, but letters in CAPTCHAs lack context.
All the above, in combination, often results in a CAPTCHA that computer can, in principle, recognize better than human. Furthermore computer does not get tired and can keep trying even if it succeeds only once per ten attempts.
Thirdly, CAPTCHA turns away undecided visitors, and may very well result in loss of revenue.
CAPTCHA works by wasting time and money on software that is forcing spammer to waste time and money.
To solve this problem, people began thinking of alternatives to CAPTCHA:
SAPTCHA.
SAPTCHA stands for Semi Automatic Public Turing Test to Tell Computers and Humans Apart.
The key concept is same as with CAPTCHA: user is presented with test question or instructions and must give correct answer to use resource. Main difference is that computer does not try to automatically generate "unique" test questions on each query; only verification of answer is automatic. Instead, unique test question and answer[s] are set by moderator or owner when SAPTCHA is installed, and are changed every time spamming happens.
SAPTCHA is proposed as more accessible alternative to CAPTCHA that may replace CAPTCHA in services such as most blogs and forums. SAPTCHA works as lightweight CAPTCHA.
The concept follows from observation that there are many cases where automated generation of unique test question or image does not add any security - spammer do not need to pass test more than once on same forum or blog. Often, there's no human spammer interacting with website at all [Indeed, every blog or site owner would love to believe that his site is so important that it is spammed personally, in a very weird way whereby rather than just reading the image with eyes, spammer would write visual recognition software, but that's in fact not happening :-)]. In such cases, static question can't be worse at stopping bot than dynamic.
Human generated questions have much broader diversity and are thus harder for computer to answer. Parsing arbitrary sentences is an unsolved problem, unlike distorted letter recognition which is a solved problem. It must be also noted that CAPTCHA itself is not really "completely automatic" - human has to write and maintain CAPTCHA software, and update it every time it is broken.
Example questions: User is given instruction like "write [no i'm not a computer!] in this text field" or "write 'i'm human' in reverse" or "write[or copy-paste] web address of this page there" (please don't use too similar things. No default questions and answers. Think up something yourself. Don't try to be clever. It should be not more complex to understand and do than rest of registration, and thus shouldn't decrease website's accessibility(!). It's better if answer is more than 1 character long.)
Bots can try to understand text written by human in normal language (very hard problem in AI) or try to guess (some delay can make it pointless) or try some common test answers if any (then, common test questions and answers will disappear)
Spammer have to manually answer the question to start spamming. This is exactly same problem as with CAPTCHA at registration. Similarly to CAPTCHA at registration, human invervention is necessary to stop spam. - account must be banned and for SAPCHA question must be changed.
In a way, SAPTCHA can be viewed as light weight disposable CAPTCHA test that is cheap to replace when it get compromised.
Comparison
Sample use scenarios
SAPTCHA
s.0) Normal user comes accross your blog. If he can answer question, he can post reply, unless you made bad question and/or instructions. If user can't read your question, probably he can't read your blog either, so the SAPTCHA shouldn't make it less accessible.
s.1) Spammer bot comes accross your blog. No spamming happens. Bots can't understand human language yet.
s.2) Spammer human comes accross your blog/forum, answer question, register account, and possibly add answer and account to spambot database or proceeds to spam manually. You are spammed. You'll have to take action manually to ban spammer and stop spam; you may also want to change the question if spamming was done by bot that "knows" answer to question.
CAPTCHA
s.0) Normal user comes accross your blog/forum. If he can see, and CAPTCHA is simple he can post reply with small hastle if he doesn't have to pass CAPTCHA every time he replies. If CAPTCHA is "unbreakable" or uses bad colors, he will need several attempts, especially so if he need to pass it for every reply. This makes it much less likely that someone will reply to your posts at all. If user is blind or otherwise can't see it, no way.
s.1) Spammer bot comes accross your blog. You might get spammed if bot can recognize image (it is possible if you are using popular CAPTCHA that was broken).
s.2) Spammer human comes accross your blog/forum. He can answer question, register account, add it to spambot database. You are spammed. It will take moderator to ban the bot, and delete spam[assuming that spam filters alone don't suffice without CAPTCHA]; so you still need human intervention from your side. As have been said before, if you'd ask to pass CAPTCHA for every message it'd be too annoying for normal users as well.
Comparison of SAPTCHA versus CAPTCHA features
Advantages of SAPTCHA over CAPTCHA:
1. SAPTCHA software is much easier to implement or replace than CAPTCHA
2. Textual SAPTCHA does not discriminate against disabled who can use internet. [Audio CAPTCHA plus visual CAPTCHA still discriminates against some people, plus the audio part is far easier for computer to break]
3. There is methods for breaking image based CAPTCHAs. If you use popular CAPTCHA, you may still get spammed by entirely automatic bot. SAPTCHAs can be much more varied and there won't be common method of breaking until it becomes possible for computers to interpret human instructions in normal human language. At which time we'd rather have to worry about things like skynet.
Advantages of CAPTCHA over SAPTCHA (disadvantages of SAPTCHA):
1. With SAPTCHA, when banning spammer, moderator must enter new question and answer. With CAPTCHA, though, there's point 1 above (& CAPTCHA code won't remain useful forever either), so for not extremely popular websites it seems highly unlikely that even in long run CAPTCHA would save work.
2. If SAPTCHA is used to protect registration, it is easier to register many accounts at once with SAPTCHA than with CAPTCHA; this might or might not matter with popular email services.
3. Verbal SAPTCHA may be problematic for multi-language resources that need frequent changes.
4. When it is something like photo gallery, visual CAPTCHA is allright as it doesn't contribute to inaccessibility.
Conclusion:
SAPTCHA can be viable alternative to CAPTCHA for web resources like forums and blogs and in other situations when spammer can not afford to target resources individually. With textual resources, SAPTCHA does not lessen accessibility of resource to disabled.
It is suggested that forum and blogging software should offer support for SAPTCHA in addition to existing support for CAPTCHA, thus allowing administrator to use SAPTCHA and switch to CAPTCHA only when and if SAPTCHA is found to be really inadequate in this situation (which is expected to happen only on very popular web resources. How popular? Millions users kind of popular). By the method of operation, SAPTCHA can give only limited protection against account registration abuses when abuser is willing to solve SAPTCHA and consequently run bot that register really many accounts (e.g. for use of email as storage), which would be prevented by CAPTCHA on every registration.

Advantages Of ERP
In the absence of an ERP system, a large manufacturer may find itself with many software applications that cannot communicate or interface effectively with one another. Tasks that need to interface with one another may involve:[citation needed]
* ERP systems connect the necessary software in order for accurate forecasting to be done. This allows inventory levels to be kept at maximum efficiency and the company to be more profitable.
* Integration among different functional areas to ensure proper communication, productivity and efficiency
* Design engineering (how to best make the product)
* Order tracking, from acceptance through fulfillment
* The revenue cycle, from invoice through cash receipt
* Managing inter-dependencies of complex processes bill of materials
* Tracking the three-way match between purchase orders (what was ordered), inventory receipts (what arrived), and costing (what the vendor invoiced)
* The accounting for all of these tasks: tracking the revenue, cost and profit at a granular level.
ERP Systems centralize the data in one place. Benefits of this include:

Some security features are included within an ERP system to protect against both outsider crime, such as industrial espionage, and insider crime, such as embezzlement. A data-tampering scenario, for example, might involve a disgruntled employee intentionally modifying prices to below-the-breakeven point in order to attempt to interfere with the company's profit or other sabotage. ERP systems typically provide functionality for implementing internal controls to prevent actions of this kind. ERP vendors are also moving toward better integration with other kinds of information security tools.
