Somatic Pairing in Drosophila virilis Mitosis

In neuroblast cells homologous chromosomes tend to pair during prophase of mitosis. Heterochromatic elements of homologous chromosomes are widely separated in very early prophase, at which time the euchromatin is poorly stained. Pairing is intimate for euchromatic portions of chromosomes in early and middle prophase with chiasmata frequently present. Homologous chromosomes most commonly lie side-by-side in late prophase and metaphase. Statistical data are presented to show the frequency of intimate pairing in prophase and side by side pairing in metaphase

Library Cataloguing and Role and Reference Grammar for Natural Language processing Applications

Several potential application of natural language processing have proven to be intractable. In this paper, we provide and overview of methods from library cataloguing and linguistics that have not yet been adopted by the natural language processing community and which could be used to help solve some of these problems

Parsing Using the Role and Reference Grammar Paradigm

Much effort has been put into finding ways of parsing natural language. Role and Reference Grammar (RRG) is a linguistic paradigm that has credibility in linguistic circles. In this paper we give a brief overview of RRG and show how this can be implemented into a standard rule-based parser. We used the chart parser to test the concept on sentences from student work. We present results that show the potential role of this method for parsing ungrammatical sentences

Action Stories for Counter Terrorism (extended abstract)

Due to the raised terrorist threat worldwide, there is an urgent need to research that assists security and police services to protect the public and key assets and to prevent attacks from taking place. Successful protection and prevention may require potential and known suspects to be monitored or arrested. These operations are high risk because inappropriate surveillance, interview or arrest may have damaging political, public relations and intelligence effects. In addition to better tracking information on which to base suspicions, the security and police services need to have confidence that operations will yield evidence that can demonstrate conclusively that a deceptive activity such as a terrorist attack was in the process of being planned or executed before an operation takes place

How to introduce yourself to patients

Rationale and key points This article explores the process of introducing yourself to patients. This is an essential interaction because it forms the basis of the therapeutic nurse-patient relationship. Effective communication skills are essential to foster therapeutic nurse-patient relationships based on mutual trust and respect. It is important to consider both verbal and non-verbal communication in patient interactions. Reflective activity Clinical skills articles can help update your practice and ensure it remains evidence based. Apply this article to your practice. Reflect on and write a short account of: 1. How this article will change your practice when meeting patients for the first time. 2. How you could use this article to educate your colleagues

The determinants of board size and composition: Evidence from the UK

This paper examines the trends and determinants of board structure for a large sample of UK firms from 1981 to 2002. We extend the predominantly US based literature in a number of important ways. Firstly, a comparative analysis of the UK and US legal and institutional settings leads us to hypothesize that UK boards will play a weaker monitoring role and hence board structures will not be determined by monitoring related factors. Our evidence supports this conjecture, showing that board structure determinants differ in predictable ways across different institutional settings. Secondly, in contrast to recent US mandatory reforms, UK reforms have been voluntary. As such they provide an interesting comparison, being arguably more effective than a mandatory approach by allowing firms to choose board structures most appropriate for their own needs. Our results support this point of view. Although the UK reforms do have a significant impact on board structures, a large number of firms choose not to comply, and those that do appear to do so for strong economic reasons. The reforms also appear to reduce the ability of well performing CEOs to influence board structures
