Pula Arena

The Pula Arena is the name of the amphitheatre located in Pula, Croatia. The Arena is the only remaining Roman amphitheatre to have four side towers and with all three Roman architectural orders entirely preserved. It was constructed in 27 BC – 68 AD and is among the six largest surviving Roman arenas in the World. A rare example among the 200 Roman surviving amphitheatres, it is also the best preserved ancient monument in Croatia.

The amphitheatre is depicted on the reverse of the Croatian 10 kuna banknote, issued in 1993, 1995, 2001 and 2004.

Construction

The exterior wall is constructed in limestone. The part facing the sea consists of three stories, while the other part has only two stories since the amphitheatre was built on a slope. The maximum height of the exterior wall is 29.40 m (96.5 ft). The first two floors have each 72 arches, while the top floor consists of 64 rectangular openings.

The axes of the elliptical amphitheatre are 132.45 and 105.10 m (434.5 and 344.8 ft) long, and the walls stand 32.45 m (106.5 ft) high. It could accommodate 23,000 spectators in the cavea, which had forty steps divided into two meniani. The seats rest directly on the sloping ground; The field for the games, the proper arena, measured 67.95 by 41.65 m (222.9 by 136.6 ft). The field was separated from the public by iron gates.

Arena (Australian publishing co-operative)

Arena is an independent Australian radical and critical publishing group. It has been publishing continuously since 1963. Currently, its principal publications are the political and cultural Arena Magazine (6 times per year), and the twice-yearly theoretical publication Arena Journal. Their concerns initially found expression in the practical and theoretical quarterly, Arena, which ran from 1963 to 1992 and was then transformed into the two different publications that continue today.

Though the quarterly Arena commenced as a New Left magazine with a commitment to extending Marxist approaches by developing an account of intellectual practices, its subsequent debates and theoretical work, and engagements with critical theory, media theory, post-structuralism and postmodernism, have led it to develop an approach known as the 'constitutive abstraction' approach. This is connected to an associated lineage of engaged theory. All of these are underpinned by a preoccupation with the questions of social abstraction, including the abstraction of intellectual practices. They include a special emphasis on the cultural and social contradictions of globalised hi-tech society, which the Arena editors took to be misrepresented within prevailing media theory and post-structuralism.

Arena (Todd Rundgren album)

Arena is an album by rock musician Todd Rundgren that was released in 2008.

Like several of his earlier albums, this was entirely a solo effort, with Rundgren playing all the instruments. In contrast to his earlier albums, he produced this album entirely on an Apple laptop computer using Propellerhead's Reason software for composition and Sonoma Wire Works' RiffWorks for recording. All audio processing was done with software tools as well, except for a Line 6 Toneport guitar input box.

Database index

A database index is a data structure that improves the speed of data retrieval operations on a database table at the cost of additional writes and storage space to maintain the index data structure. Indexes are used to quickly locate data without having to search every row in a database table every time a database table is accessed. Indexes can be created using one or more columns of a database table, providing the basis for both rapid random lookups and efficient access of ordered records.

An index is a copy of select columns of data from a table that can be searched very efficiently that also includes a low-level disk block address or direct link to the complete row of data it was copied from. Some databases extend the power of indexing by letting developers create indices on functions or expressions. For example, an index could be created on upper(last_name), which would only store the upper case versions of the last_name field in the index. Another option sometimes supported is the use of partial indices, where index entries are created only for those records that satisfy some conditional expression. A further aspect of flexibility is to permit indexing on user-defined functions, as well as expressions formed from an assortment of built-in functions.

Index (statistics)

In statistics and research design, an index is a composite statistic – a measure of changes in a representative group of individual data points, or in other words, a compound measure that aggregates multiple indicators. Indexes summarize and rank specific observations.

Much data in the field of social sciences is represented in various indices such as Gender Gap Index, Human Development Index or the Dow Jones Industrial Average.

Item in indexes are usually weighted equally, unless there are some reasons against it (for example, if two items reflect essentially the same aspect of a variable, they could have a weight of 0.5 each).

Constructing the items involves four steps. First, items should be selected based on their face validity, unidimensionality, the degree of specificity in which a dimension is to be measured, and their amount of variance. Items should be empirically related to one another, which leads to the second step of examining their multivariate relationships. Third, indexes scores are designed, which involves determining their score ranges and weights for the items. Finally, indexes should be validateds, which involves testing whether they can predict indicators related to the measured variable not used in their construction.
