Archaeologists use the exponential, radioactive decay of carbon 14 to estimate the death dates of organic material. The stable form of carbon is carbon 12 and the radioactive isotope carbon 14 decays over time into nitrogen 14 and other particles. Carbon is naturally in all living organisms and is replenished in the tissues by eating other organisms or by breathing air that contains carbon. At any particular time all living organisms have approximately the same ratio of carbon 12 to carbon 14 in their tissues. When an organism dies it ceases to replenish carbon in its tissues and the decay of carbon 14 to nitrogen 14 changes the ratio of carbon 12 to carbon Experts can compare the ratio of carbon 12 to carbon 14 in dead material to the ratio when the organism was alive to estimate the date of its death. Radiocarbon dating can be used on samples of bone, cloth, wood and plant fibers. The half-life of a radioactive isotope describes the amount of time that it takes half of the isotope in a sample to decay.

Working out what an employee gets paid for taking a day off on annual holidays will depend in part, on what they have earned in the previous 12 months. For an employee who takes all or part of their annual holiday entitlement, the annual holidays are paid at the rate of at least the greater amount of:. Both of these calculations need to be done every time the employee takes annual holidays.
They apply to all employees taking entitled annual holidays. Annual holidays are paid at the rate of the greater of ordinary weekly pay and average weekly earnings. Ordinary weekly pay is the amount an employee receives under his or her employment agreement for an ordinary working week, including:.
Calculating annual holiday payment rates
We have already seen how we can use a dictionary to group related data together, and how we can use functions to create shortcuts for commonly used groups of statements. A function performs an action using some set of input parameters. Not all functions are applicable to all kinds of data.
Annual holidays are paid at the rate of the greater of ordinary weekly pay and date for annual holiday and the effect of parental leave on payment for annual.
A renounceable right is an offer issued by a corporation to shareholders to purchase more shares of the corporation’s stock, usually at a discount. This offer usually coincides with the company’s decision to issue a new round of stock, which would dilute the shareholders’ equity in the company. The renounceable right compensates the shareholders for that dilution. Also called a rights offering , renounceable rights have a value and can be traded separately from the original shares held.
During a rights offering, existing common stock shareholders are allowed to purchase newly issued shares at a discount to the price that will be offered to the public at a later date. Shareholders have the “right” to increase their investment exposure in the company’s stock. However, shareholders can renounce that right, meaning that they can trade those rights on the open market. The number of additional shares that are offered to shareholders is typically in proportion to their existing shares owned.
Companies typically perform a renounceable right when they’re looking to generate capital or money. The money raised as a result of the offering could be used to invest back into the company by purchasing fixed assets , such as equipment, machinery, or a new building. Companies also use the funds from a rights offering to pay down debt, particularly if the company could not obtain any more credit from their bank.
The offering also prevents the company from having to pay interest expense on the debt had they borrowed the funds from a bank or issued bonds to investors. Issuing additional shares could also be a faster way to raise cash versus applying for a borrowing facility. Companies that are financially struggling might use this method of raising capital to improve their balance sheet and financial viability.

Dating is a stage of romantic relationships in humans whereby two people meet socially with the aim of each assessing the other’s suitability as a prospective partner in an intimate relationship. It is a form of courtship , consisting of social activities done by the couple, either alone or with others. The protocols and practices of dating, and the terms used to describe it, vary considerably from country to country and over time. While the term has several meanings, the most frequent usage refers to two people exploring whether they are romantically or sexually compatible by participating in dates with the other.
With the use of modern technology, people can date via telephone or computer or just meet in person. Dating may also involve two or more people who have already decided that they share romantic or sexual feelings toward each other.

You can view a summary and all related details for a selected tax year. The reported tax information may not reflect all adjustments necessary for tax reporting purposes and may not be appropriate for use in preparing a tax return. You should use the official tax forms that Fidelity sends by mail for purposes of tax return preparation. Mutual fund distributions are taxable based on the record date of the distribution.
For example, mutual fund distributions declared as payable to shareholders of record in December, and paid in January, are taxable as of the December tax year. These distributions are not included in the December account statement, but do appear in the January account statement when the dividends are paid and are reflected as income in December here. Dividend information is based on information known to Fidelity as of the date listed.
Adjustments and reclasses may occur through the early part of the subsequent tax year as additional information is made available. As new information becomes available updates are included online and on Form DIV. OID reports the earned portion of the difference between the stated redemption price at maturity if greater than one year and the issue price of a bond, debenture, note, or other evidence of indebtedness issued at a discount e.
Tax reporting of OID obligations is complex; if you paid acquisition or bond premium, or if the obligation is a stripped bond or stripped coupon, you must compute the proper amount of OID.

It is set to zero if unused. Data Subtype Code is an integer code further defining categories of data in a CRSP object that otherwise have the same structure, such as the difference between a return and price data item. The Data Subtype Code for portfolio assignments and statistics time series is set to the INDNO of the index group with portfolio results for the market segment portfolio type. Delisting Code is a 3-digit integer code. It either 1 indicates that a security is still trading or 2 provides a specific reason for delisting.
All coded delistings are categorized by the first digit of the delisting code. The second and third digits of the delisting codes provide further detail of delisting events. Additional delisting codes, specific to various delisting categories, have been created to indicate when an issue is closed to further research, or if the issue is pending further research. See here for a listing of codes describing categories of delisting events.
If the security is still active, Delisting Date is set to the last date of available price data. Delisting date is never missing. Monthly: Delisting Date is not necessarily a month-end trading date and might not be included in the Calendar Trading Date array of monthly time series. This date is set to zero if the security is still active.

It is also the oldest, dating back to the eighteenth century and the work of Carl Friedrich Gauss and Adrien-Marie Legendre. It is also one of the easier and more intuitive techniques to understand, and it provides a good basis for learning more advanced concepts and techniques. This post explains how to perform linear regression using the statsmodels Python package.
We will discuss the single variable case and defer multiple regression to a future post. This is part of a series of blog posts to show how to do common statistical learning techniques in Python.

Active Support is the Ruby on Rails component responsible for providing Ruby language extensions, utilities, and other transversal stuff. It offers a richer bottom-line at the language level, targeted both at the development of Rails applications, and at the development of Ruby on Rails itself. In order to have a near-zero default footprint, Active Support does not load anything by default. It is broken in small pieces so that you can load just what you need, and also has some convenience entry points to load related extensions in one shot, even everything.
For every single method defined as a core extension this guide has a note that says where such a method is defined. In the case of blank? Active Support has been carefully revised so that cherry-picking a file loads only strictly needed dependencies, if any. The next level is to simply load all extensions to Object. That does not even put the entire Active Support in memory upfront indeed, some stuff is configured via autoload , so it is only loaded if used.
A Ruby on Rails application loads all Active Support unless config. In that case, the application will only load what the framework itself cherry-picks for its own needs, and can still cherry-pick itself at any granularity level, as explained in the previous section. The method present?

Radiometric dating , radioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbon , in which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay. Together with stratigraphic principles , radiometric dating methods are used in geochronology to establish the geologic time scale.
By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change. Radiometric dating is also used to date archaeological materials, including ancient artifacts. Different methods of radiometric dating vary in the timescale over which they are accurate and the materials to which they can be applied.
All ordinary matter is made up of combinations of chemical elements , each with its own atomic number , indicating the number of protons in the atomic nucleus. Additionally, elements may exist in different isotopes , with each isotope of an element differing in the number of neutrons in the nucleus. A particular isotope of a particular element is called a nuclide.
Some nuclides are inherently unstable. That is, at some point in time, an atom of such a nuclide will undergo radioactive decay and spontaneously transform into a different nuclide. This transformation may be accomplished in a number of different ways, including alpha decay emission of alpha particles and beta decay electron emission, positron emission, or electron capture. Another possibility is spontaneous fission into two or more nuclides.
