Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Human Resource Development climate and organizational citizenship behavior: a comparative study of Banking industry.
The aim of the present study was to inspect and explore the relationship between Human Resource Development Climate (HRD C) and Organizational Citizenship Behavior (OCB). In this study, Human Resource Development Climate (HRD C) was treated as an independent variable and Organizational Citizenship Behavior (OCB) as a dependent variable. The relationship between the independent and dependent variable was explored using Pearson’s coefficient of correlation and simple linear regression analysis. Demographic variables undertaken in this study includes; Nature of Organization, name of the organization, gender, age, tenure, and length of the service. These demographic variables have also been explored through inferential analysis using t-test, and One way ANOVA. Based on the literature support, five dimensional model conceptually proposed by organ in year 1988 and empirically validated by Podsakoff et al. in year 1990 has been used in the present study to measure Organizational Citizenship Behavior (OCB) among the employees of sample organizations. This five dimensional model of OCB includes sub-variables namely, Altruism, Conscientiousness, courtesy, civic-virtue and Sportsmanship. Whereas, a scale developed by the pioneer of HRD Climate concept Rao and Abraham (1990), is the sole measure available in the literature to measure HRD climate. It has three elements namely; General Climate, OCTAPACE Culture, and HRD Mechanisms. The present study has been conducted in the banking industry, with the two banks from private sector {namely, Jammu and Kashmir bank (JKB) and Housing development and financial corporation (HDFC)} and two banks from public sector {State bank of India (SBI) and Punjab national bank (PNB)}. The present study is based on the responses collected from 316 Branch Heads, who have been selected as a choice of source with the aim to avoid the common method variance based on the recommendations available in the literature.Digital copy of Ph.D thesis.University of Kashmir
Appropriate Similarity Measures for Author Cocitation Analysis
We 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

Security Aspects & Performance Analysis of Mobile & IP Networks
Computer and Mobile Networks are characterized by two attributes which impact end-user perception about the quality of the service received. These attributes are the performance and the level of security experienced by the end-user.
In this thesis an attempt has been made to characterize the security and performance aspects of computer and mobile networks, by dividing (based on the thrust areas) the thesis into 4 chapters, each covering important fundamentals, current & emerging issues as well as potential future research work related to each of the 4 thrust areas.
2. Security of IPv6-based Networks
2.1 IPv6 Overview
While the basic function of the Internet Protocol is to move information across net-works, IPv6 has more capabilities built into its foundation than IPv4. A key capabil¬ity is the significant increase in address space. For example, all devices could have a public IP address, so that they can be uniquely tracked . Today inventory manage¬ment of dispersed assets in a very large distributed organization such as the DRDO cannot be achieved with IPv4 mechanisms; during the inventory cycle some¬one has to manually verify the location of each desktop computer. With IPv6 one can use the network to verify that such equipment is there; even non-IT equipment in the field can also be tracked by having an IP address permanently assigned. IPv6 also has extensive automatic configuration (auto-configuration) mechanisms and reduces the IT burden by making configuration essentially plug-and-play (auto con¬figuration implies that a Dynamic Host Configuration Protocol (DHCP) server is not needed or does not have to be configured). Since IPv4 manual configuration is already a challenge in itself, one can understand that manually manipulating IPv6 addresses that are four times longer can be much more problematic. Corporations and government agencies will be able to achieve a number of improvements with IPv6. IPv6 can improve a firm's intranet, with benefits such as, but not limited to:
• Expanded addressing capabilities
• Serverless autoconfiguration (what some call plug-n-play) and reconfigu¬ration
• Streamlined header format and flow identification
• End-to-end security, with built-in, strong IP-layer encryption and authentica¬tion (embedded security support with mandatory IPsec implementation)
• In IPv6, creating a VPN is easier and more standard than in IPv4, because of the (Authentication Header (AH) and Encapsulating Security Protocol (ESP))
• Extension headers. The performance penalty is lower for the VPN implemented in IPv6 compared to those built in IPv4 [10]
• Enhanced support for multicast and QoS (more refined support for Flow Control and QoS for the near real-time delivery of data)
• More efficient and robust mobility mechanisms (enhanced support for Mobile IP and Mobile Computing Devices).
• Extensibility: improved support for feature options/extensions. IPv6 makes it easy for nodes to have multiple IPv6 addresses on the same network interface. This can create the opportunity for users to establish overlay or Communities of Interest (COI) networks on top of other physical IPv6 networks. Department, groups, or other users and resources can belong to one or more COIs, where each can have its own specific security policy [10]
• Merging two IPv4 networks with overlapping addresses (say, if two organiza-tions merge) is complex; it will be much easier to merge networks with IPv6
• IPv6 network architectures can easily adapt to an end-to-end security model where the end hosts have the responsibility of providing the security services necessary to protect any data traffic between them; this results in greater flexibility for creating policy-based trust domains that are based on varying parameters including node address and application [9]
Dispelling the Myths Behind First-author Citation Counts
We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
