Is Medical Check-Up Useful for Physician among New University Students During Enrolling Time to University? a Survey of 640 New University Students
No full textAim: The aim of this study is to investigate the health problems of the recently enrolled new university students in Celal Bayar University, Manisa, Turkey and to expose whether the information gathered will be useful for the future follow up of the students. Methods: 640 students who were elected by the Students' Selection and Ranking Examination (Öǧrenci Seçme Sinavi-OSS), had been contributed in our study during enrolling time to university; September 2006. Our sample had been constituted of students coming from very different regions, representing the Turkish student population. Results: 42.7% of subjects were male and 57.3% were female. Following prevalence are found for diseases and addictions: Headache 10.8%, allergy 7.3%, anemia 5.8%, gastritis 5.8%, smoking 39.6%, alcohol drinking 2.4%, epilepsy 1.4%, recovered tuberculosis 0.6%. Female students had suffered much more headache, gastritis, anemia than male students (respectively p= 0.000, p= 0.037 and p=0.000). 55.7% of the male students and 27.5% of the female students were smokers. All of the drinkers were male. Headache and gastritis had been found associated with each other (Spearman r=0.259, p=0.000). Headache was found higher in subjects with epilepsy than others (p= 0.020). Conclusion: Physicians of school based health centers, firstly, must understand students' health problems. This study emphasizes the importance of health screening of enrolling students in the registration time and the necessity of school based health centers

Nonlinear vibrations and stability of an axially moving beam with an intermediate spring support: two-dimensional analysis
No full textThe nonlinear coupled longitudinal-transverse vibrations and stability of an axially moving beam, subjected to a distributed harmonic external force, which is supported by an intermediate spring, are investigated. A case of three-to-one internal resonance as well as that of non-resonance is considered. The equations of motion are obtained via Hamilton’s principle and discretized into a set of coupled nonlinear ordinary differential equations using Galerkin’s method. The resulting equations are solved via two different techniques: the pseudo-arclength continuation method and direct time integration. The frequency-response curves of the system and the bifurcation diagrams of Poincaré maps are analyzed.Mergen H. Ghayesh, Marco Amabili, Michael P. Païdoussi

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

No full textThis book addresses the topic of leadership in healthcare. There is a great deal of rhetoric around leadership, this book explores the rhetoric with papers that contribute insights into taking healthcare forward in the 21st Century, and the nature of leadership in healthcare and organizational forms that are leading the field. The book promotes Organizational behavior in healthcare as a serious academic field that can provide insights of use to managers, professionals, and policy makers in the healthcare area
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
