subjects: ICT

abstract: This research was conducted to investigate the Saudi science teachers' perception of the
use of Information and Communication Technology (ICT) tools to enhance teaching and
learning and undertake a small and groundwork examination of these teachers current use
of ICT.
It draws on the interpretive paradigm (Cohen  Manion, 1994), where the focus is on
how people interpret and make sense of their world. From this interpretive perspective
the beliefs of Saudi secondary school science teachers, in relation to the benefits of ICT,
their current use of ICT and their perceived needs for improvement in the use of ICT in
the classroom were investigated.
Saudi secondary schools science teachers from both girls' and boys' schools in three
different types of schools have been involved in this study. There were 28 government
schools (9 girls' and 19 boys' schools), four small schools in rented premises (2 girls'
and 2 boys' schools) and four Aramco schools (1 girls' and 3 boys' schools). These
schools were in different districts: Aldammam city, Alkhobar city, Aldahran city,
Alqateaf city and Sufwa city. The teachers were asked to voluntarily participate in the
study and 131 teachers out of 200 (86 male and 45 female, 65 %) completed the
questionnaire. Analysis of the data, together with the relevant literature builds a picture
of the use of ICT in science education. Providing ICT hardware and software resources to
a school is not enough to ensure significant developments in use of ICT for teaching and
learning in Saudi science classrooms. Access to working ICT continues to be an issue for
these teachers. Although teachers identified many benefits to teachers and students from
using ICT and had made individual efforts to develop their use of ICT for admin
planning and lesson preparation, they also identified barriers. These barriers focused on a
lack of appropriate professional development and technical support.
The findings have implications for future development in the area of ICT. It is expected
that the results of the research will guide future research and development in the country
and outline the importance of the use of information and communication technology in
education for teachers, students, parents and decision-makers. It will contribute
information towards decision-making and planning in future projects.

title: Structural insight into DNA joining: from conserved mechanisms to diverse scaffolds.

authors: Williamson, Adele

abstract: DNA ligases are diverse enzymes with essential functions in replication and repair of DNA; here we review recent advances in their structure and distribution and discuss how this contributes to understanding their biological roles and technological potential. Recent high-resolution crystal structures of DNA ligases from different organisms, including DNA-bound states and reaction intermediates, have provided considerable insight into their enzymatic mechanism and substrate interactions. All cellular organisms possess at least one DNA ligase, but many species encode multiple forms some of which are modular multifunctional enzymes. New experimental evidence for participation of DNA ligases in pathways with additional DNA modifying enzymes is defining their participation in non-redundant repair processes enabling elucidation of their biological functions. Coupled with identification of a wealth of DNA ligase sequences through genomic data, our increased appreciation of the structural diversity and phylogenetic distribution of DNA ligases has the potential to uncover new biotechnological tools and provide new treatment options for bacterial pathogens.

title: Review: Memoirs of Active Service

authors: Cheesman, Sue

subjects: Maaka Pepene

abstract: Ka maumahara tonu tatou ki a ratou - we will remember them…poignant last words…   bidding farewell to a generation of veterans moving on...leaving fragments  of memories and diaries for children/grandchildren to honour, celebrate and remember …black costumes billow, fold, swirl and wrap the dancers bodies…wide sweeping arm movements…jumps and turns…slides on all fours - provides the vehicle for five accomplished dancers to fill the space with fluidity and lyricism in this very moving finale, a lament set to Albinoni’s adagio - maybe old soldiers never die.
