Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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

Full text linkAim The aim of this study was to measure primary and secondary implant stability through the resonance frequency analysis of mandibular implants and to evaluate the influence of implant diameter and length, sex, age and site. Materials and methods Thirty-six healthy patients who had mandibular implants placed were enrolled for the study. a total of 82 Osseospeed TX (astra Tech implant system – dentsply implants; Mölndal, Sweden) implants were placed, with different lengths (9, 11 and 13 mm) and diameters (3.5 and 4 mm). all implants were placed according to a conventional two-stage surgical procedure. implant stability quotients (isQ) were recorded at implant placement (isQ1) and 3 months later, at second surgical stage (isQ2). statistical analysis was performed to investigate significant differences between implant dimensions, patient sex and age, and implant position (anterior or posterior sites). siGMaPLOT software was used for statistical analysis (significance =0.05). Results secondary implant stability was statistically significantly higher compared to initial isQ values (p<0.05). isQ2 values were statistically significantly higher than isQ1 values for 3.5 mm diameter implants, for 13 mm length implants and for implants placed in anterior mandible. age was not found to influence implant stability. Female patients showed isQ2 values significantly higher than males. Conclusion some parameters such as implant dimensions and positions may influence only the secondary implant stability. Male patients have lower secondary implant stability
