The successful implementation of e-government transformation: A case study in Oman
The aim of this paper is to investigate, and to discuss the key critical factors that facilitate the successful implementation of E-government projects. The nature of this research is mainly qualitative. This investigation uses a single case study and data was mainly collected by means of semi-structured interviews and organisational documents from the Ministry of Higher Education in Oman. The research findings suggest that there are three paradigms which each include a set of factors that impacts the success of E-government success namely, organisational paradigm, technology paradigm and end-users paradigm. The authors believe that, this paper demonstrates an added value to the current literature on transformation of E-government and to E-government projects success, within the wider context of E-government implementation projects. Also the research will benefit organisations in the public sector, as it has identified main key success factors in E-government transformations and implementations
A Cerebellar High-Grade Neuroepithelial Tumour with BCOR Alteration in a five-year-old Child: A case report.
New groups of high-grade neuroepithelial tumours (HGNET) have emerged from the reclassification of central nervous system (CNS) embryonal tumours that have recognised CNS HGNET with BCOR alteration (CNS HGNET-BCOR). We report a two-year, nine-month-old Omani boy who presented to the Royal Hospital, Muscat, Oman, in 2015 with subacute head tilting and neck pain. A well-defined cerebellar lesion was found and he was treated with standard chemoradiotherapy. After a relapse at the age of five years, molecular testing revealed a BCOR alteration. He was treated with further surgery and high-dose chemotherapy; unfortunately, he relapsed and died three years after he was diagnosed
Total energy expenditure in obese Kuwaiti primary school children assessed by the doubly-labelled water technique
The aim of this pilot study was to assess body composition and total energy expenditure (TEE) in 35 obese 7â9 years old Kuwaiti children (18 girls and 17 boys). Total body water (TBW) and TEE were assessed by doubly-labeled water technique. TBW was derived from the intercept of the elimination rate of deuterium and TEE from the difference in elimination rates of 18O and deuterium. TBW was used to estimate fat-free mass (FFM), using hydration factors for different ages and gender. Fat mass (FM) was calculated as the difference between body weight and FFM. Body weight was not statistically different but TBW was significantly higher (p = 0.018) in boys (44.9% ± 3.3%) than girls (42.4% ± 3.0%), while girls had significantly higher estimated FM (45.2 ± 3.9 weight % versus 41.6% ± 4.3%; p = 0.014). TEE was significantly higher in boys (2395 ± 349 kcal/day) compared with girls (1978 ± 169 kcal/day); p = 0.001. Estimated physical activity level (PAL) was significantly higher in boys; 1.61 ± 0.167 versus 1.51 ± 0.870; p = 0.034. Our results provide the first dataset of TEE in 7â9 years old obese Kuwaiti children and highlight important gender differences to be considered during the development of school based interventions targeted to combat childhood obesity

Investigations into stability in the fig/ fig-wasp mutualism
Fig trees (Ficus, Moraceae) and their pollinating wasps (Chalcidoidea, Agaonidae) are
involved in an obligate mutualism where each partner relies on the other in order to
reproduce: the pollinating fig wasps are a fig treeâs only pollen disperser whilst the fig
trees provide the wasps with places in which to lay their eggs. Mutualistic interactions
are, however, ultimately genetically selfish and as such, are often rife with conflict. Fig
trees are either monoecious, where wasps and seeds develop together within fig fruit
(syconia), or dioecious, where wasps and seeds develop separately. In interactions
between monoecious fig trees and their pollinating wasps, there are conflicts of interest
over the relative allocation of fig flowers to wasp and seed development. Although fig
trees reap the rewards associated with wasp and seed production (through pollen and
seed dispersal respectively), pollinators only benefit directly from flowers that nurture
the development of wasp larvae, and increase their fitness by attempting to oviposit in
as many ovules as possible. If successful, this oviposition strategy would eventually
destroy the mutualism; however, the interaction has lasted for over 60 million years
suggesting that mechanisms must be in place to limit wasp oviposition.
This thesis addresses a number of factors to elucidate how stability may be
achieved in monoecious fig systems. Possible mechanisms include: 1) a parasitoidcentred
short ovipositor hypothesis in Ficus rubiginosa, which suggests that a subset of
flowers are out of reach to parasitoid ovipositors making these ovules the preferred
choice for ovipositing pollinators and allowing seeds to develop in less preferred ovules;
2) the presence of third-party mutualists such as non-pollinating fig wasps (F. burkei)
and patrolling green tree ants on the fig surface (F. racemosa) that limit pollinator and
parasitoid oviposition respectively; and 3) selection on fig morphology which constrains
the size (and therefore fecundity) of the associated pollinators. I discuss the lack of
evidence for a single unifying theory for mutualism stability and suggest that a more
likely scenario is the presence of separate, and perhaps multiple, stabilising strategies in
different fig/ fig-wasp partnerships
