Agricultural productivityAgricultural productivity is measured as the ratio of agricultural outputs to inputs. While individual products are usually measured by weight, which is known as crop yield, varying products make measuring overall agricultural output difficult. Therefore, agricultural productivity is usually measured as the market value of the final output. This productivity can be compared to many different types of inputs such as labour or land. Such comparisons are called partial measures of productivity.
Science museumA science museum is a museum devoted primarily to science. Older science museums tended to concentrate on static displays of objects related to natural history, paleontology, geology, industry and industrial machinery, etc. Modern trends in museology have broadened the range of subject matter and introduced many interactive exhibits. Modern science museums, increasingly referred to as 'science centres' or 'discovery centres', also feature technology.
Marginal propensity to saveThe marginal propensity to save (MPS) is the fraction of an increase in income that is not spent and instead used for saving. It is the slope of the line plotting saving against income. For example, if a household earns one extra dollar, and the marginal propensity to save is 0.35, then of that dollar, the household will spend 65 cents and save 35 cents. Likewise, it is the fractional decrease in saving that results from a decrease in income.
Patriarchal crossThe Patriarchal cross is a variant of the Christian cross, the religious symbol of Christianity, and is also known as the Cross of Lorraine. Similar to the familiar Latin cross, the patriarchal cross possesses a smaller crossbar placed above the main one so that both crossbars are near the top. Sometimes the patriarchal cross has a short, slanted crosspiece near its foot (Russian Orthodox cross). This slanted, lower crosspiece often appears in Byzantine Greek and Eastern European iconography, as well as in other Eastern Orthodox churches.
Average propensity to saveIn Keynesian economics, the average propensity to save (APS), also known as the savings ratio, is the proportion of income which is saved, usually expressed for household savings as a fraction of total household disposable income (taxed income). The ratio differs considerably over time and between countries. The savings ratio for an entire economy can be affected by (for example) the proportion of older people (as they have less motivation and capability to save), and the rate of inflation (as expectations of rising prices can encourage people to spend now rather than later) or current interest rates.
Health indicatorHealth indicators are quantifiable characteristics of a population which researchers use as supporting evidence for describing the health of a population. Typically, researchers will use a survey methodology to gather information about a population sample, use statistics in an attempt to generalize the information collected to the entire population, and then use the statistical analysis to make a statement about the health of the population. Health indicators are often used by governments to guide health care policy or to make goals for improving population health.
Accounts receivableAccounts receivable, abbreviated as AR or A/R, are legally enforceable claims for payment held by a business for goods supplied or services rendered that customers have ordered but not paid for. The accounts receivable process involves customer onboarding, invoicing, collections, deductions, exception management, and finally, cash posting after the payment is collected. These are generally in the form of invoices raised by a business and delivered to the customer for payment within an agreed time frame.
Expert witnessAn expert witness, particularly in common law countries such as the United Kingdom, Australia, and the United States, is a person whose opinion by virtue of education, training, certification, skills or experience, is accepted by the judge as an expert. The judge may consider the witness's specialized (scientific, technical or other) opinion about evidence or about facts before the court within the expert's area of expertise, to be referred to as an "expert opinion".
