Global FORMAT setting

The header and format parameters might also use variables rendering the dc, image and content namespace information. Note, that only bits of interest have been implemented so far and those namespaces might not be implemented fully yet.

Rendering the dc namespace

The following variables are extracting the dc namespace info, that could be used in header and format. Nnote, that some of the variables are already used above. This is done by purpose to use different feeds with the same formating parameters. If there's a conflict the non-dc tags have higher precedence, i.e. a <title> content </title> is prefered over <dc:title> content </dc:title> .

  • $title: channel/article title (dc:title)
  • $creator: channel creator (dc:creator)
  • $subject: subject text; this will also add an image according to the subject hash list, see above (dc:subject)
  • $description: ... (dc:description)
  • $publisher: the channel/article publisher (dc:publisher)
  • $contributor: ... (dc:contributor)
  • $date: ... (dc:date)
  • $type: ... (dc:type)
  • $format: ... (dc:format)
  • $identifier: ... (dc:identifier)
  • $source: ... (dc:source)
  • $language: ... (dc:language)
  • $relation: ... (dc:relation)
  • $coverage: ... (dc: coverage)
  • $rights: ... (dc: rights)

Rendering the image namespace

An image:item is converted into an <img> tag using the following mappings:

  • src: image url (rdf:about attribute of the image.item tag)
  • alt: image title (title)
  • width: image width (image:width)
  • height: image height image:height)

Rendering the content namespace

The variable $content is refering to the <content:encoding> content </content:encoding>.

These 4 Emotions Lead to Investing Mistakes

There's often little logic in the movements of the market, and it can be easy to make investing mistakes.

This is because stocks move at the whim of human beings, who can often be illogical and driven by emotions. Plenty of technical and fundamental analyses have been done on equities. However, one their most important influences is human psychology. Realizing this can help you learn how to invest better and avoid investing mistakes.

Psychology is a vital but under-appreciated element of stock trading. Thisis because most analysts are more mathematically focused. But those who ignore the human and social aspects of the market are making a serious mistake.

If you’re trying to raise money for your startup by trading stocks, it’s better to take a broad view. Of course you’ll want to study the market’s trends, but you might also want to consider boning up on a little Psychology 101, especially as it relates to your own trading style.

Let’s look at the four different emotions whichinfluence most investors’ decisions. They are greed, fear, hope, and regret.





Greed is the desire for money and wealth. When a trader experiences greed, they are only able to think about how much money they have made from a stock and how much more they can make by keeping their position.

The problem? You won’t realize a profit until after you have closed your position. Until this happens, a trader only has the potential for profit. Greed can lead to an investor holding a stock for longer than they should, hoping to make more money&hellip until it plummets.



Fear,which is probably the strongest of all human emotions, causes a trader to sell a position regardless of its price. Unlike other emotions, fear is a survival response.

The Dow Jones Industrial Average (DJIA) in the U.S. took from 1983 until 2007-24 years-to grow from 1,000 to 14,200. However, it only took two years to lose 50% of its value, between 2007 and 2009. That's the power of fear.

Fear can be beneficial if it gets you out of a poor trade. But it's dangerous when it causes investors not to buy a stock which would otherwise be profitable.



Hope,a feeling of expectation and desire, might be the second most dangerous emotion. It's what keeps a trader in an unprofitable position.

When a losing stock decides to goup, investors will often stay, in the hope of recouping past losses. This is dangerous because the market will do what it does, regardless of an investor's wishes.




Regret is a feeling of disappointment over something whichhappened. Itcan cause a loss of focus.

It's natural to regret making a bad trade or missing a good one. But an investor must simply learn from what went wrong and move to the next opportunity. This is the only way to ever learn how to invest better.


Know Thyself

Market psychology can be a very powerful tool. Tradersusually just wonder if they shouldbuy or sell a stock. Instead, you should watch the market for trends and then ask yourself, ''How are my emotions affecting my trading decisions?''

Find the Best Mobile Plan for Your Home-Based Business

When you are starting a home-based business there is sometimes little or no point in having a landline phone. However, the chances are that you will still need a good mobile plan for a phone to use for your business. Whether it is customer facing or something you use to keep in touch with colleagues or contractors, you will want the best deal you can get. And you’ll want one that includes calls and texts as well as mobile data.


Finding the Best Mobile Plan

There are a few things you need to consider to find the best mobile plan for your company. For a start, the size of your company and number of staff need to be considered. Also how much you need to use mobile data will be something that you should factor in.


Use a Comparison Website

Many websites like Broadband Choices give you the opportunity to compare and contrast different plans together. All of the main providers now do business contracts, so you should be able to find one with a network that you know and trust.




Don’t Be Afraid to Ask for Extras

If you do not see what you want on the mobile plan that looks the most desirable to you, you can always call the provider and ask them if you can make switches or changes. Some networks will understand that you might not need one part of the service as much as the other, and they may let you add more of what you need to cut something else out. Most likely, the staff will be willing to make allowances to keep an interested customer like you.


Think Ahead

Chances are if you are a home-based business, you have just started out. This means that your mobile contract will only need to be for yourself or maybe a couple of others. Talk through the contract terms with the network. Some are for a year, but there are others that are 18 months. If your company has grown significantly by then, will you have the opportunity to add more mobile handsets and contracts easily?


What Are the Current Offers?

Now that so many people are taking the plunge and working for themselves, business mobile phone contracts are commonplace. All of the large networks have now made sure they have at least one available business-specific contract available.


EE Business Value Plans

EE offers a number of different plans for businesses. The contracts start from as little as 23 per month with nothing to pay initially for the handset. You can choose between the latest Samsung and iPhone models. Further, most contracts have 2GB of data at least with unlimited calls and texts. Quite a lot of the plans for businesses on EE call for 24-month contracts. This would suit someone who knows what their business plan is longer term.


Vodafone Business Value

Vodafone also offers a business value plan for those small businesses which may only be a single entrepreneur or a couple of people working from a home. They start from 18 per month for 500mb 4G data and unlimited UK calls and texts. You can add extras to the Vodafone business mobile plan that will assist with the smooth running of your business day to day. For an extra 5 per month you can get unlimited roaming in more than 60 countries, for example, and they have an add-on insurance plan, too. This means they will replace your handset within 4 hours to any address in the UK should you experience a problem.



Three Business 900

The Three mobile business 900 plan gives small business customers an iPhone 7 handset with all-you-can-eat data. In contrast to the other plans, the data is unlimited but the calls and texts are capped. For 46.37 per month you get 1,625 cross-network minutes and 2,000 Three-mobile-to-Three-mobile minutes. You also get 1,150 texts and 100 landline minutes. The only drawback to this plan is that there is a 99 upfront cost. However, the plan includes quite a lot and the handset is fairly up to date.
