ABSTRACT: The anticipation and forecast of technological changes
are of vital importance, as technological advances become increasingly fast and complex. What is at the core is identification of the current technologies that will drive technological changes over the coming few years. In this respect, numerous approaches have been devised to assess future technological impacts based on patent citation information, but do not provide a fair reflection of dynamic and idiosyncratic aspects of technological impacts as they are deterministic methods based on simple citation counts. We propose a stochastic patent citation analysis that can assess future technological impacts in a time period of interest by employing the future citation count as a proxy. At the heart of the proposed approach is a Pareto/NBD (Negative Binomial Distribution) model for taking into account the dynamic and idiosyncratic aspects of technological impacts. A patent citation matrix is first constructed for each time unit with citation patterns of the past. The future technological impacts are then derived by Pareto/NBD sub-model and gamma- gamma sub-model. A case study of the display technology patents is presented to illustrate the proposed approach. We believe our method can be employed in various research fields, from narrow patent valuation, to broad technological analysis and planning. (C) 2011 Elsevier Inc. All rights reserved.

KEYWORDS: Pakistani journals; Impact Factor
ABSTRACT: Objective: To summarizes the performance of Pakistani
journals in terms of their Impact Factor.
Methodology: Pakistani journals were analyzed for their impact factor (IF), citations and publications from 2000-2009. Journal Citation Reports
(JCR) published by Thomson Reuter was used to retrieve the data electronically. All tables and graphical presentations were generated by using either Minitab version-10 or MS-Excel for Macintosh.
Results: Total seven journals have their IF in the year 2009. Only two Pakistani Bio-medical journals. have an international impact factor listed by JCR. The highest impact factor of any Pakistani journal is
0.825 in 2009 of Pakistan Journal of Pharmaceutical Sciences. In the year 2009, Journal of College of Physicians and Surgeons Pakistan (JCPSP) and Pakistan Journal of Medical Sciences (PJMS) were included in the list of IF journals for the very first time after 13 and 26 years of their first publication respectively. The IF of JCPSP is 0.554 and PJMS is 0.203 for the year of 2009.
Conclusion: There is a very small contribution by Pakistani journals in terms of ISI indexation. Basic sciences journal continues to overshadow in term of 151 indexation with highest impact factor of 0.825 by Pakistan Journal of Pharmaceutical Sciences.

ABSTRACT: Background: Systematic reviews are not an assembly of
anecdotes but a distillation of current best available evidence on a particular topic and as such have an important role to play in evidence- based healthcare. A substantial proportion of these systematic reviews focus on interventions, and are able to provide clinicians with the opportunity to understand and translate the best available evidence on the effects of these healthcare interventions into clinical practice. The importance of systematic reviews in summarising and identifying the gaps in evidence which might inform new research initiatives is also widely acknowledged. Their potential impact on practice and research makes their methodological quality especially important as it may directly influence their utility for clinicians, patients and policy makers. The objectives of this study were to identify systematic reviews of oral healthcare interventions published in the Journal of Applied Oral Science (JAOS) and to evaluate their methodological quality using the evaluation tool, AMSTAR. Methods: Potentially eligible systematic reviews in JAOS were identified through an electronic search of the Scientific Electronic Library Online (SciELO). Details of the relevant aspects of methodology as reported in these systematic reviews were extracted from the full text publications. Methodological quality was assessed independently by two reviewers using the AMSTAR questionnaire. Results: Five systematic reviews were identified, one of which was subsequently excluded as it was a review of a diagnostic test. Summary AMSTAR scores for the four included reviews were: 1, 5, 2 and 4 out of a maximum score of 11 (range 1-5, mean 3) with only one of the reviews scoring 5. Conclusion: AMSTAR evaluation of the methodological quality of the relatively small number of systematic reviews published in JAOS illustrated that there was room for improvement. Pre-publication and editorial appraisal of future systematic reviews might benefit from the application of tools such as AMSTAR and is to be recommended.
