He had 108 publications during 1961 – 2001 in domains: Molecular Biology of Cell Cycle Regulation (43), Genetics of Cell Division (48), Genomic Re-arrangement and DNA Repair (9), Molecular Genetics of Yeast Cell Fission (5), and Drug Target Interaction (3) which were analysed for authorship pattern with his 101 collaborators. Most active researchers having number of publications with Leland H. Hartwell were : Weinert, T. A. (10), Garvik, B. M. (8), McLaughlin, C. S. (8), Jenness, D. D. (5). His productivity coefficient was 0.76 which clearly indicates that his productivity increased after 50 percentile age. Highest collaboration coefficient (1) for Leland H. Hartwell was found during 1963-1965, 1968-1969, 1977, 1981-1983, 1985-1990, 1996 and 1998-2001.

Bibliographics for the 983 eprints in the live archives of E-LIS : trends and status report up to 7th July 2004, based on author-self-archiving metadata
No full textThe priority for ideas and philosophy related to "Network Theory" have been traced back and documented by Braun(2004),and credit goes to Karinthy(1929).The IT has empowered to realise it, as the most practical phenomena and it is no more a humour. The OAI (Open Archives Initiatives)and ACIS (Academic Contributor Information System)are progressive in the direction ,which may lead to realise the "Collective Genius" at global level. Focus of present study is on Author-Self-Archiving (A-S-A)Metadata of the 983 Eprints in the Live Archives of the E-LIS (EPrints of Library and Information Science),which were approved till 7th July 2004.The A-S-A Metadata was used for librametric analysis. Self-explanatory bibliographics are illustrated.The highlights include: Conference papers (34%); highest approval, June 2004 (28%); published archives (76%);not refereed (52%); not in public domain (60%); highest self-archiving-author (De Robbio, Antonella).The Nos. of EPrints having single JITA domain specifications were: Theoretical and general aspects of libraries and information(27); Information use and sociology of information(80);Users,literacy and reading(13);Libraries as physical collections(30);Publishing and legal issues(57);Management(13);Industry, profession and education(36);Information sources, supports, channels(113) ; Information treatment for information services, Information functions and techniques (101); Technical services libraries, archives and museums(25); Housing technologies(1); Information technology and library technology(92); and Inter-domainery (395) i.e. having specifications of two or more than two JITA classes
From hospital contributory schemes to health cash plans: mutualism in health care in the post-war period.
No full textThe article traces the post-war history of the British hospital contributory schemes, which had developed during the inter-war years to the point where, through the accumulation of small weekly contributions from a mass membership, they provided substantial proportions of hospital income. A minority of contributory schemes remained in existence post-1948, but their subsequent development has received little attention. Some evolved into provident associations offering private health insurance; others remained committed to the provision of low-cost benefits to a blue-collar clientele, and continued to be known as hospital contributory schemes. This article outlines the principal features of the contributory schemes' contemporary history. We first explore why many schemes decided to continue in existence. The next section uses national and individual scheme records to delineate the market niche which they captured and to investigate their role in post-war health provision, relative to the state system. In particular we trace the decline of convalescent home benefit, and the gradual trend towards a more uniform benefit package, of which optical and dental grants were the most popular. We then survey patterns of membership and account for the main trends in support for cash plan products since 1950. Finally, we ask to what extent the schemes were able to retain their character as a ‘movement’ with distinctive mutualist and charitable features, particularly in the more competitive environment of the later twentieth century
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
Individual voluntary participation in the United Kingdom: an overview of survey information
No full textThe measurement of voluntary activity is not straightforward; definitional and methodological questions affect the responses. This is true within the context of the UK but also in other countries of the developed world (Archambault 1993, Kendall and Knapp 1993, Gidron and Katz 1998, Salamon and Sokolowski 2001). The existence of definitional difficulties and ambiguities has a detrimental impact on the quality of academic research and policy-making in this sphere. Firstly, it impedes orderly collection of statistical information on volunteering in administrative sources. Also, it complicates the collection of survey information: the absence of well-understood and widely-agreed concepts of voluntarism in the public mind introduces uncertainty in people’s responses. To date, however, there has not been an attempt to compare findings of different surveys systematically. This paper aims to fill the gap in research by reviewing the available surveys for the UK. It focuses specifically on the methods used to obtain information on volunteering and the comparability of the results generated by different surveys

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
