A new design method based on artificial bee colony algorithm for digital IIR filters

Digital filters can be broadly classified into two groups: recursive (infinite impulse response (IIR)) and non-recursive (finite impulse response (FIR)). An IIR filter can provide a much better performance than the FIR filter having the same number of coefficients. However, IIR filters might have a multi-modal error surface. Therefore, a reliable design method proposed for IIR filters must be based on a global search procedure. Artificial bee colony (ABC) algorithm has been recently introduced for global optimization. The ABC algorithm simulating the intelligent foraging behaviour of honey bee swarm is a simple, robust, and very flexible algorithm. In this work, a new method based on ABC algorithm for designing digital IIR filters is described and its performance is compared with that of a conventional optimization algorithm (LSQ-nonlin) and particle swarm optimization (PSO) algorithm.     

Collaborative information seeking: A field study of a multidisciplinary patient care team

Multidisciplinary teams are an essential aspect of modern organizational work. These teams often work in information-rich environments but little is known about their collaborative information seeking (CIS) behavior. We have been studying the CIS behavior of teams in the context of medical care. We conducted an ethnographic field study of a multidisciplinary patient care team in an emergency department to identify (a) team information needs and (b) situations that trigger collaborative information seeking activities. We identified seven categories of information needs as expressed by questions asked by team members. The majority of questions focused on medical information, but there were a larger than expected percentage of questions focusing on organizational information. We also identified three triggers for CIS activities. These triggers are: (1) lack of expertise, (2) lack of immediately accessible information, and (3) complex information needs. The questions and triggers highlight the importance of face-to-face communication during CIS activities and how CIS activities could lead to interruptive workplaces. We also discuss organizational and technical implications for supporting CIS behavior of teams.     

Ranking of field association terms using Co-word analysis

Information retrieval involves finding some desired information in a store of information or a database. In this paper, Co-word analysis will be used to achieve a ranking of a selected sample of FA terms. Based on this ranking a better arranging of search results can be achieved. Experimental results achieved using 41 MB of data (7660 documents) in the field of sports. The corpus was collected from CNN newspaper, sports field. This corpus was chosen to be distributed over 11 sub-fields of the field sports from the experimental results, the average precision increased by 18.3% after applying the proposed arranging scheme depending on the absolute frequency to count the terms weights, and the average precision increased by 17.2% after applying the proposed arranging scheme depending on a formula based on “TF∗IDF” to count the terms weights.     

Patrick Geddes and Museum ideas in Dundee and Beyond

One of the first things Patrick Geddes did on taking up the post of Professor of Botany at University College, Dundee was to establish a botanical museum. Throughout his life museums were of great importance to him, and were central to his theories as an educationalist. The Outlook Tower in Edinburgh was the most famous demonstration of these theories, but this short introductory paper also looks at less well known aspects of them, such as his ground-breaking paper to the Museums Association conference in Dundee in 1907, his unpublished book.

Agency problem, institutions, and technology policy: Explaining Taiwan's semiconductor industry development

Taiwan has made significant progress in the semiconductor industry with government agencies and bureaucrats as the driving forces over the past 30 years. Taiwan's impressive achievement in the semiconductor industry clearly indicates that the government failures and agency problem usually associated with deep government involvement did not occur in Taiwan. Why is that the case? This paper proposes a principal-agent framework for technology policy and applies the framework to discuss the institutional arrangements through which bureaucrats were controlled effectively in executing the semiconductor industry policies in Taiwan. By analyzing the institutional and organizational arrangements Taiwanese leaders made to mitigate the agency problem, this paper brings bureaucrats into the popular developmental state theory and emphasizes that the success of state intervention should not be taken for granted, and it also brings politics into technology policy analysis and stresses the importance and complexity of agency problem in technology policy.     

The 2001 Benjamin Franklin medal in physics presented to Alan Guth, Ph.D. of Cambridge, Massachusetts

The Franklin Institute, Philadelphia, Pennsylvania, awarded the 2001 Benjamin Franklin Medal in Physics to Alan H. Guth for his efforts to advance our knowledge of physical science and its application of the inflationary scenario, in which the universe undergoes a rapid expansion in the first stages of the Big Bang.     

Implementing and Assessing Library Reference Training Programs

Comprehensive assessments have shown that academic library users prefer a welcoming environment that provides the opportunity for self-sufficiency. Libraries need to meet these expectations and improve the quality of library reference by creating a comprehensive training program for librarians, staff, and students. This article will review standards for reference training in academic libraries with a focus on one-desk service points and consider best practices for planning, implementing, and assessing training programs for staff, students, and librarians.     

Defining and Communicating What “Intercultural” and “Intercultural Communication” Means to Us

In order to engage in our larger discussion, we needed to share our definitions, framings, and theorizings of what “intercultural” and “intercultural communication” mean to us and how we inflect these based on our own experiences, identities, and perspectives. Discussants break down how they understand the notion of “intercultural” behind commonly used and circulated terms in our scholarship.
