Enterprise portals: addressing the organisational and individual perspectives of information systems
Enterprise portals are being viewed as the next generation application platform of choice, offering benefits over both client/server and thin client arrangements. By providing a mediating layer between the information applications and resources of the organisation and the individuals using them, enterprise portals appear to provide a unique context to allow both the organisational and individual perspectives of information systems to be addressed. This study seeks to examine these often competing perspectives of information systems by using an exploratory empirical survey to investigate the actual deployment of enterprise portals within a range of different organisations. It is found that both the individual and organisational benefits that enterprise portals can offer appear to have been recognised, and coherent sets of services addressing each of these perspectives are being developed. Consistent with diffusion and acceptance of technology models, organisations appear to be commencing their portal developments with services that will ensure utilisation by individuals, and are subsequently seeking to realise organisational level benefits
The co-production of historical knowledge: implications for the history of identities
This essay argues that understanding peopleâs lives, emotions and intellectual reasoning is crucial to exploring national identity and that âthe co-production of historical knowledgeâ provides an approach or methodology that allows for a deeper comprehension of peopleâs self-identities by encouraging a diverse range of people to participate in the research process. We argue that many academic historians have maintained an intellectual detachment between university history and public and community history, to the detriment of furthering historical knowledge. We argue for a blurring of the boundaries between university and communities in exploring modern British history, and especially the history of national identities. It includes extracts of writing from community partners and a brief photographic essay of projects related to exploring identities
Methodology for C-glycosylation and synthesis of probes for the detection of cysteine containing proteins
Throughout my research I have been able to expand my knowledge and gain experience in organic chemistry by working on projects related to biochemistry and hydrocarbons. The projects I have worked on were: Project 1: C-glycosylation through photo irradiation with reductive halide atom transfer Project 2: Synthesis of rhodamine and biotin probes for the detection of cysteine containing proteins Project 3: Literature review on: Fluorescent probes for cysteine containing protein

Synthesis, Characterization, and Reactivity Studies of para-Substituted Triaryltin Cobaloximes
Several six-coordinate cobaloxime compounds containing a triaryltin ligand were synthesized and characterized. These cobaloximes include (4- t-BuPy)Co(DH)2Sn(C6H4-p -tolyl)3, (4-t-BuPy)Co(DH)2Sn(C 6H4-p-t-Bu)3, (NH3)Co(DH) 2SnPh3, and (4-t-BuPy)Co(DH)2Bn. (4-t-BuPy)Co(DH)2Sn(C6H4- p-tolyl)3 crystallized in the centrosymmetric triclinic space group P-1 (Z=4) with unit cell dimensions a = 13.2949(5) A, b = 17.7508(7) A, c = 18.2240(7) A, alpha = 107.1983(13)°, beta = 91.6597(13)°, gamma = 107.6992(12)°, and Volume = 3880.5(3) A 3. The structure was isostructural with other alkyl cobaloximes. Preliminary X-ray structure analysis determined that (NH3)Co(DH)2SnPh 3 had a NH3 ligand bound to the six-coordinate octahedral cobalt center and trans to the triaryltin ligand. The para-substituted cobaloximes were synthesized through a Gringard reaction to obtain the tetraaryltin species, SnAr4, followed by an adapted Jolly redistribution procedure to obtain the triaryltin chloride species, ClSnAr3. The SnAr 4 compounds synthesized were Sn(C6H4- p-tolyl)4, Sn(C6H4-p-t-Bu) 4, and Sn(C6H4-p-OCH3) 4. The ClSnAr3 complexes synthesized successfully were ClSn(C 6H4-p-tolyl)3 and ClSn(C 6H4-p-t-Bu)3. These ClSnAr 3 complexes were used as the tin ligand to synthesize the corresponding cobaloxime compounds. Once synthesized, the cobaloximes underwent halogen cleavage titrations to investigate the effects of changes in the cobaloxime coordination environment and to compare their reactivity to that of the Co III(OEP)SnPh3. The multiple products formed through these halogen cleavage reactions indicates that the Co-Sn bond is not cleaved cleanly for these cobaloximes, unlike the porphyrins compounds. The cobaloximes react with the halogens to first cleave the Sn-C bonds through electrophilic aromatic substitution, indicating that cleavage of the Sn-C bond is more facile than cleavage of the Co-Sn bond in these compounds

Campus and consortium in an era of large-scale research: An historical study of the Virginia Associated Research Center, 1962-1967
A large agency of the Federal Government, three public institutions of higher learning, and two agents of State Government in the Commonwealth of Virginia launched a federally funded research and education consortium in 1962. The Virginia Associated Research Center (VARC) promised great success. The University of Virginia, Virginia Polytechnic Institute, and The College of William and Mary joined forces to provide the National Aeronautics and Space Administration\u27s Langley Research Center with a scientific research base and a graduate education program. The Commonwealth initially provided enthusiastic support from the Governor\u27s office and from the State Council for Higher Education.;The three colleges agreed to cooperatively manage and operate the NASA Space Radiation Effects Laboratory on the Virginia Lower Peninsula. NASA funded the costs of operating the laboratory, gave the colleges research time for experiments and provided the colleges with large multidisciplinary grants. In return, the colleges were to set up graduate education programs for NASA employees. These graduate programs were to grant degrees from the respective institutions for course work taken at the VARC site on the Peninsula. The research function of the consortium proved to be more productive than the education function.;Certain criteria for successful and unsuccessful consortia were ascertained from the literature. VARC\u27s characteristics were analyzed according to these specific criteria. The three institutions could not agree on how to operate the facility. Inherently weak governance structures in the consortium led to the failure of the venture; after only five years, the consortium dissolved. The Governor of Virginia placed the Center under the auspices of the college nearest the Peninsula, The College of William and Mary. Though unsuccessful as a consortium, VARC became a means to achievement for the three colleges. Each of the three gained stronger, more reputable physics departments and two of the institutions achieved modern university status. A qualitative analysis emerges as the consortium\u27s operation and characteristics unfold through oral history. The study details circumstances which led to VARC\u27s demise and simultaneously describes a key transitional period for The College of William and Mary in its three hundred year history
