Feature selection

Rationale: ICTs have changed the way information is created and distributed. They have also changed the way libraries select, acquire, organize and deliver information. Library automation has. By the end of the lesson you should be able to: Define library automation Define an automated/Integrated Library System and identify as general features. Be aware of standards. Define an online public access catalog/web catalog Indentify the binifit of Library automation Identify potentail difficult in imple menting library automation ...

The primary objective of this research is to provide an account of the ways in which elite higher education institutions adapt and respond to external institutional logics for social inclusion practices. In particular, it explores and investigates the pattern of elite public universities’ social inclusion practices as a result of government higher education policy frameworks and higher education market features. It also aims to uncover variations between the four selected elite universities in Australia and Malaysia in regard to social inclusion practices.

In this paper we address the problem of extracting features relevant for predicting protein±protein interaction sites from the three-dimensional structures of protein complexes. Our approach is based on information about evolutionary con-servation and surface disposition. We implement a neural network based system, which uses a cross validation proce-dure and allows the correct detection of 73% of the residues involved in protein interactions in a selected database comprising 226 heterodimers.

The dimeric structure of seminal ribonuclease (BS-RNase) is maintained by noncovalent interactions and by two intersubunit disulfide bridges.Another unusual feature of this enzyme is its antitumour action, consisting in a cyto-toxic activity selective for malignant cells.This cytotoxic action is exerted when the protein reaches the cytosol of the affected cells, where it degrades ribosomal RNA, thus blocking protein synthesis and leading cells to death.

Studies on horseradish peroxidase C and other haem peroxidases have been carried out on selected mutants in the distal haem cavity providing insight into the functional importance of the distal residues. Recent work has dem-onstrated that proximal structural features can also exert an important influence in determining the electronic structure of the haem pocket.

Salvinorin A is a potent kappa opioid receptor (KOP) agonist with unique structural and pharmacological properties. This non-nitrogenous ligand lacks nearly all the structural features commonly associated with opioid ligand binding and selectivity. This study explores the structural basis to salvinorin A binding and selectivity using a combination of chimeric and single-point mutant opioid receptors.

WAGE RETURNS FOR POST -SECONDARY EDUCATION: A COMPARISON FOR SELECTED PROGRAMS BY LEVELS OF EDUCATION AND INDUSTRY TYPE The potential effects of school choice programs depend critically on what characteristics parents value in schools. Hanushek, for example, notes that parents might not choose effective schools over others that are less effective but offer “pleasant surroundings, athletic facilities, [and] cultural advantages,” (1981, p. 34). To the extent that parents choose productive schools, market discipline can induce greater productivity from school administrators and teachers.

Key features of Seedling Seed Orchard (1) - A seedling seed orchard is developed by selectively thinning a progeny trial which tests many different families of a species. - The progeny trial is assessedand analysedto find out which families and trees within families are growing best. - Inferior trees are removed in two or more selective thinnings, as the stand develops. - Inferior families may be completely removed –all trees cut down.
