An Examination of Lotka’s law in the Field of Library and Information Studies

The purpose of this study was to test Lotka’s law of scientific publication productivity using the methodology outlined by Pao (1985), in the field of Library and Information Studies (LIS). Lotka’s law has been sporadically tested in the field over the past 30+ years, but the results of these studies are inconclusive due to the varying methods employed by the researchers. A data set of 1,856 citations that were found using the ISI Web of Knowledge databases were studied. The values of n and c were calculated to be 2.1 and 0.6418 (64.18%) respectively. The Kolmogorov-Smirnov (K-S) one sample goodness-of-fit test was conducted at the 0.10 level of significance. The Dmax value is 0.022758 and the calculated critical value is 0.026562. It was determined that the null hypothesis stating that there is no difference in the observed distribution of publications and the distribution obtained using Lotka’s and Pao’s procedure could not be rejected. This study finds that literature in the field of library and Information Studies does conform to Lotka’s law with reliable results. As result, Lotka’s law can be used in LIS as a standardized means of measuring author publication productivity which will lead to findings that are comparable on many levels (e.g., department, institution, national). Lotka’s law can be employed as an empirically proven analytical tool to establish publication productivity benchmarks for faculty and faculty librarians. Recommendations for further study include (a) exploring the characteristics of the high and low producers; (b) finding a way to successfully account for collaborative contributions in the formula; and, (c) a detailed study of institutional policies concerning publication productivity and its impact on the appointment, tenure and promotion process of academic librarians.

Joint Information and Jamming Beamforming for Secrecy Rate Maximization in Cognitive Radio Networks

In this paper, we consider the secure beamforming design for an underlay cognitive radio multiple-input singleoutput broadcast channel in the presence of multiple passive eavesdroppers. Our goal is to design a jamming noise (JN) transmit strategy to maximize the secrecy rate of the secondary system. By utilizing the zero-forcing method to eliminate the interference caused by JN to the secondary user, we study the joint optimization of the information and JN beamforming for secrecy rate maximization of the secondary system while satisfying all the interference power constraints at the primary users, as well as the per-antenna power constraint at the secondary transmitter. For an optimal beamforming design, the original problem is a nonconvex program, which can be reformulated as a convex program by applying the rank relaxation method. To this end, we prove that the rank relaxation is tight and propose a barrier interior-point method to solve the resulting saddle point problem based on a duality result. To find the global optimal solution, we transform the considered problem into an unconstrained optimization problem. We then employ Broyden-Fletcher-Goldfarb-Shanno (BFGS) method to solve the resulting unconstrained problem which helps reduce the complexity significantly, compared to conventional methods. Simulation results show the fast convergence of the proposed algorithm and substantial performance improvements over existing approaches.

The role of networking and social media tools during job search: an information behaviour perspective.

The paper presents a critical analysis of the extant literature pertaining to the networking behaviours of young jobseekers in both offline and online environments. A framework derived from information behaviour theory is proposed as a basis for conducting further research in this area. Method. Relevant material for the review was sourced from key research domains such as library and information science, job search research, and organisational research. Analysis. Three key research themes emerged from the analysis of the literature: (1) social networks, and the use of informal channels of information during job search, (2) the role of networking behaviours in job search, and (3) the adoption of social media tools. Tom Wilson’s general model of information behaviour was also identified as a suitable framework to conduct further research. Results. Social networks have a crucial informational utility during the job search process. However, the processes whereby young jobseekers engage in networking behaviours, both offline and online, remain largely unexplored. Conclusion. Identification and analysis of the key research themes reveal opportunities to acquire further knowledge regarding the networking behaviours of young jobseekers. Wilson’s model can be used as a framework to provide a holistic understanding of the networking process, from an information behaviour perspective.

On the application of contextual IoT service discovery in Information Centric Networks

The continuous flow of technological developments in communications and electronic industries has led to the growing expansion of the Internet of Things (IoT). By leveraging the capabilities of smart networked devices and integrating them into existing industrial, leisure and communication applications, the IoT is expected to positively impact both economy and society, reducing the gap between the physical and digital worlds. Therefore, several efforts have been dedicated to the development of networking solutions addressing the diversity of challenges associated with such a vision. In this context, the integration of Information Centric Networking (ICN) concepts into the core of IoT is a research area gaining momentum and involving both research and industry actors. The massive amount of heterogeneous devices, as well as the data they produce, is a significant challenge for a wide-scale adoption of the IoT. In this paper we propose a service discovery mechanism, based on Named Data Networking (NDN), that leverages the use of a semantic matching mechanism for achieving a flexible discovery process. The development of appropriate service discovery mechanisms enriched with semantic capabilities for understanding and processing context information is a key feature for turning raw data into useful knowledge and ensuring the interoperability among different devices and applications. We assessed the performance of our solution through the implementation and deployment of a proof-of-concept prototype. Obtained results illustrate the potential of integrating semantic and ICN mechanisms to enable a flexible service discovery in IoT scenarios.

COMMUNICATION, SUBJECT, CULTURE: JOYS AND SOLITUDE INAUGURAL LECTURE OF THE SCHOOL YEAR 2002 OF THE SCHOOL OF LIBRARY, DOCUMENTATION AND INFORMATION

When you are invited to offer a conference like this, can not stop having a series of questions and considerations about the very fact of speaking to an audience informed and educated about the issues that the title might suggest exposure and how without falling into the usual cliches, without repeating the views and opinions set forth, if not obvious. I propose, then, establish, as a starting point, two things: the first is a promise: I will not talk about internet, a recurrent theme in his classes and activities. The second is a kind of contract between you and me: check out the obviousness of some views and question it, see it from behind, because that is where we might find the seams, some of the patches, if not outright nudity. I wonder if this is not precisely one of the first tasks of teaching in the University: to force what seems obvious to justify its obviousness, which is not easy.We can start messing things up a bit, looking like a very smooth and made ​​some surrealist poets to cut one by one the words of poems and writings, throw them into the air and read with amazement the order they fall to form a new verse, Perhaps more interesting and evocative than the first. Is not this somewhat random operation of new blends the fundamental operation of so many new discoveries and innovative ideas in the fields of science, culture, arts? Some of you know the thought of Pascal says: "Do not say that I am not proposing something new: the order in which the material presented is different."

Inauguration Speech of the school year 1993 of the School of Library, Documentation and Information

Since the child starts in the teaching - learning is made aware that there is a division of natural resources: renewable and nonrenewable. It also says that every natural resource is useless unless it explodes. But to apply such resources necessary knowledge. We realize today that the same biological systems of living things (renewable resources) are transmitters of information. He uses that information to nurture their knowledge, and this is essential for the use and conservation of resources, making valid then the principle that "there is no knowledge without information."

The library of the Institute of Alajuela address the information and communication technologies: User training and information literacy

The Library of the Institute of Alajuela made an induction experience and training of users and ventured into the information literacy and engaged in the work of the teaching-learning as an integral part of the curriculum. The actions of the library in developing search strategies, location, selection and use of information brought inthe health service, changes to the role of the library, the librarian, the book and the information in the educational environment.By sharing this experience is intended to provide information that can motivate staff of educational institutions that wish toenter the field of information literacy as a strategy to support the development oflifelong independent learning skills and meaningful learning. Currently, the library should be a proactive part in the education of students but also teachers, administrative and family.This will result in a benefit to Costa Rica: the development of youth and their proper integration into the workplace.
