Effective date

An effective date or as of date is the date upon which something is considered to take effect. This may be different from the date upon which the event actually occurs or is recorded.

In Reserve Fund Planning, an effective date refers to the fiscal-year's first day where changes, voted on at a condo or strata corporation Annual General Meeting (AGM), take effect regardless of whether the vote took place before or after the beginning of the fiscal-year. This effective date is when recommendations take place.

Effectiveness

Effectiveness is the capability of producing a desired result. When something is deemed effective, it means it has an intended or expected outcome, or produces a deep, vivid impression.

Etymology

The origin of the word "effective" stems from the Latin word effectīvus, which means creative, productive or effective. It surfaced in Middle English between 1300-1400 A.D.

Usage

In mathematics, effective is sometimes used as a synonym of algorithmically computable.

In physics, an effective theory is, similar to a phenomenological theory, a framework intended to explain certain (observed) effects without the claim that the theory correctly models the underlying (unobserved) processes.

In heat transfer, effectiveness is a measure of the performance of a heat exchanger when using the NTU method.

In medicine, effectiveness relates to how well a treatment works in practice, as opposed to efficacy, which measures how well it works in clinical trials or laboratory studies.

In management, effectiveness relates to getting the right things done. Peter Drucker reminds us that “effectiveness can and must be learned.”.

First date

A first date is any type of initial meeting between two individuals, whether or not previously acquainted, where an effort is made to ask, plan, and organize some sort of social activity. Dating can vary between cultures, lifestyles, religion, gender, and sexual orientation.

In many countries and cultures, it is the process that romantic relationships are developed and future spouses are found. Often, people are set up on dates by their friends, or they meet the individual at work, a party, in class or online.

Purpose of a date

The purpose of a first date is the same as the purpose of any date. Because they often set the tone for the relationship, first dates are highly important. As the study by Mary Claire Morr Serewicz of the Department of Human Communication Studies at the University of Denver, and Paul Mongeau of Arizona State University, states that first dates "represent an important early event in the development of dating relationship." For example, if a date doesn’t go according to one's standards, the couple might choose to only be platonically involved, which means having no romantic relationship. However, if the date was successful and both parties’ goals were accomplished a second date might be lined up. First dates represent potential relational turning points in an individual's life.

Range query (data structures)

In data structures, a range query consists of preprocessing some input data into a data structure to efficiently answer any number of queries on any subset of the input. Particularly, there is a group of problems that have been extensively studied where the input is an array of unsorted numbers and a query consists in computing some function on a specific range of the array. In this article we describe some of these problems together with their solutions.

Problem statement

We may state the problem of range queries in the following way: a range query on an array of n elements of some set , denoted , takes two indices , a function defined over arrays of elements of and outputs . This should be done space and time efficient.

Consider for instance and an array of numbers, the range query computes , for any . These queries may be answered in constant time and using extra space by calculating the sums of the first elements of and storing them into an auxiliary array , such that contains the sum of the first elements of for every .Therefore any query might be answered by doing .
