Prevalence of tooth loss in Saudi Arabian school children: an epidemiological study of Saudi male children
No full textThe present study was carried out to determine the prevalence of tooth loss in Saudi male children with
adolescent dentition. Five hundred school-children were investigated, selected randomly from Riyadh
City. The age group of the examined sample ranged from 13 years and 6 months to 14 years and 6 months.
Clinical and radiographic examination were performed. The findings revealed that the total prevalence
of lost teeth, including extractions, hypondontia, and trauma was 13.6%. Tooth extraction was the most
dominating cause of tooth loss (8.6%), followed by hypodontia (4%) and trauma (1%). The mandibular
first molar was the most frequently extracted tooth, the mandibular second premolar showed the highest frequency
of agenesis and the central incisors were mainly affected by trauma.Corresponding Author:

East Midlands Research into Ageing Network (EMRAN) Discussion Paper Series
No full textAcademic geriatric medicine in Leicester
.
There has never been a better time to consider joining us. We have recently appointed a
Professor in Geriatric Medicine, alongside Tom Robinson in stroke and Victoria Haunton,
who has just joined as a Senior Lecturer in Geriatric Medicine. We have fantastic
opportunities to support students in their academic pursuits through a well-established
intercalated BSc programme, and routes on through such as ACF posts, and a successful
track-record in delivering higher degrees leading to ACL post. We collaborate strongly
with Health Sciences, including academic primary care. See below for more detail on our
existing academic set-up.
Leicester Academy for the Study of Ageing
We are also collaborating on a grander scale, through a joint academic venture focusing
on ageing, the ‘Leicester Academy for the Study of Ageing’ (LASA), which involves the
local health service providers (acute and community), De Montfort University; University
of Leicester; Leicester City Council; Leicestershire County Council and Leicester Age UK.
Professors Jayne Brown and Simon Conroy jointly Chair LASA and have recently been
joined by two further Chairs, Professors Kay de Vries and Bertha Ochieng. Karen
Harrison Dening has also recently been appointed an Honorary Chair.
LASA aims to improve outcomes for older people and those that care for them that takes
a person-centred, whole system perspective. Our research will take a global perspective,
but will seek to maximise benefits for the people of Leicester, Leicestershire and Rutland,
including building capacity. We are undertaking applied, translational, interdisciplinary
research, focused on older people, which will deliver research outcomes that address
domains from: physical/medical; functional ability, cognitive/psychological; social or
environmental factors. LASA also seeks to support commissioners and providers alike for
advice on how to improve care for older people, whether by research, education or
service delivery. Examples of recent research projects include: ‘Local History Café’
project specifically undertaking an evaluation on loneliness and social isolation; ‘Better
Visits’ project focused on improving visiting for family members of people with dementia
resident in care homes; and a study on health issues for older LGBT people in Leicester.
Clinical Geriatric Medicine in Leicester
We have developed a service which recognises the complexity of managing frail older
people at the interface (acute care, emergency care and links with community services).
There are presently 17 consultant geriatricians supported by existing multidisciplinary
teams, including the largest complement of Advance Nurse Practitioners in the country.
Together we deliver Comprehensive Geriatric Assessment to frail older people with
urgent care needs in acute and community settings.
The acute and emergency frailty units – Leicester Royal Infirmary
This development aims at delivering Comprehensive Geriatric Assessment to frail older
people in the acute setting. Patients are screened for frailty in the Emergency
Department and then undergo a multidisciplinary assessment including a consultant
geriatrician, before being triaged to the most appropriate setting. This might include
admission to in-patient care in the acute or community setting, intermediate care
(residential or home based), or occasionally other specialist care (e.g. cardiorespiratory).
Our new emergency department is the county’s first frail friendly build and includes
fantastic facilities aimed at promoting early recovering and reducing the risk of hospital
associated harms.
There is also a daily liaison service jointly run with the psychogeriatricians (FOPAL); we
have been examining geriatric outreach to oncology and surgery as part of an NIHR
funded study.
We are home to the Acute Frailty Network, and those interested in service developments
at the national scale would be welcome to get involved.
Orthogeriatrics
There are now dedicated hip fracture wards and joint care with anaesthetists,
orthopaedic surgeons and geriatricians. There are also consultants in metabolic bone
disease that run clinics.
Community work
Community work will consist of reviewing patients in clinic who have been triaged to
return to the community setting following an acute assessment described above.
Additionally, primary care colleagues refer to outpatients for sub-acute reviews. You will
work closely with local GPs with support from consultants to deliver post-acute, subacute,
intermediate and rehabilitation care services.
Stroke Medicine
24/7 thrombolysis and TIA services. The latter is considered one of the best in the UK
and along with the high standard of vascular surgery locally means one of the best
performances regarding carotid intervention

Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Recent Russian Debate on Moving from VAT to Sales Taxes and Its Global Implications
No full textWe discuss recent policy debate in Russia on moving from the present value added tax to a sales tax structure covering households, government and exports. What is distinctive in this debate is the range and nature of problems identified with the VAT, most of which stem from its multistage credit-invoice mechanism. These include false credit and refund claims, delays and difficulties in obtaining legitimate input credits and refunds reflecting responses of tax authorities to false claims, difficulties for large firms dealing with small firms, and resulting uneven effective tax rates between energy and manufacturing sectors. For the Russian economy being heavily dependent on oil and gas exports and seeking diversification, the VAT effectively places industrial companies at a significant disadvantage, particularly compared to exporters of energy resources. These problems are all intensified by the relatively high statutory rate of 18% in the Russian VAT. We describe and document the debate, discussing in detail what the perceived Russian problems with the VAT are. We suggest that many of the difficulties reflect the multi staging in the credit-invoice mechanism in the VAT, rather than the VAT per se. We discuss the possible use of the subtraction and addition methods in the VAT as an alternative to the sales tax proposed. We also report estimates of possible changes in effective tax rates across sectors if the sales tax were enacted. The final outcome of this debate is not yet known. A special commission of the Presidential Executive Office of the Russian Federation was to report on the matter in 2009, however, due to the economic crisis a decision on VAT/sales tax has been postponed. Despite this, in the near future a change to a sales tax could possibly follow. We suggest that were this to occur this would be a precedent setting move away from the value added tax. With IMF and World Bank conditionality no longer the force that it was for policy change in large economies such as Russia, India, China and Brazil, similar re-examinations could follow elsewhere.
Crack behavior of heat treated sintered steel under cyclic loading / Al Emran Ismail
No full textFatigue crack nucleation and initiation at particles or defects in materials have been the interest of many researchers over the past years . This is because the understanding of theses phenomena would provide a better understanding of production of new fatigue resistanc e materials. In this study a test was developed to evaluate the fatigue properties and to observe fatigue crack nucleation and initiation in sintered steel. The fatigue test was carried out on polished specimens which was based on plate bending gives balanced biaxial tension. The experimental results shows that there were mixed mode of crack nucleation and initiation such that most cracks initiated at the interface of particles and matrix especially at high stress values . Cracks were also observed to initiate at voids and beneath the surface. Quenched specimens which were tempered between temperature range of 300°C and 600°C shows similar crack initiation mechanisms. The significant differenc e between as-rece ived and tempered specimens was that the number of cycles to fail due to di fferences in material hardne ss and internal defect s. The result s of the experimentation are discussed in the light of possible micro crack toughening at the crack tip and the presence of residual stresses due, to temperature changes. It is believed that some effects of residual stresses at the surface and beneath playa role in the nucleation of crack in sinter ed steel
