- Description:
- Historically, web crawlers/bots/spiders have been well known for indexing, ranking websites on the internet. This thesis augments the crawling activity but approaches the problem through the lens of a data engineer. Whirlpool as a continuous, topical web crawling tool is also a data ingestion pipeline implemented from bottom-up using RabbitMQ which is a high performance messaging buffer to organize the data flow within its network. It is based on a open, standard blueprint design of mercator. This paper discusses the high and low level design of this complex program covering auxiliary data structures, object-oriented design, addressing scalability concerns, and deployment on AWS. The project name Whirlpool is used as an analogy referring to the naturally occurring phenomenon where opposing water currents in sea cause water to spin round and round drawing various objects into it.

- Description:
- Submitted to the Journal of Graph Theory, 1/07. and In this paper we review the spectral properties of the hypercube graph Qn and derive the Walsh functions as eigenvectors of the adjacency matrix. We then interpret the Walsh functions as states of the hypercube, with vertices labeled +1 and -1, and elucidate the regularity of the induced vertex neighborhoods and subcubes. We characterize the neighborhoods of each vertex in terms of the number of similar (same sign) and dissimilar (opposite sign) neighbors and relate that to the eigenvalue of the Walsh state. We then interpret the Walsh states as states of the inhibitory hypercube network, a neural network created by placing a neuron at each corner of the hypercube and -1 connection strength on each edge. The Walsh states with positive, zero, and negative eigenvalues are shown to be unstable, weakly stable, and strongly stable states, respectively.

- Description:
- Hiring tenure track faculty is one of the most important decisions in higher education. Hiring outcomes shape faculty careers, the process is costly and time consuming and, ultimately, hiring significantly impacts the character of academic departments and institutions. Despite its central importance, hiring is often driven by past practices with little regard for empirical data concerning "successful" hiring. The hiring process at California State University Channel Islands, a startup campus with an alternative approach to faculty hiring, may offer useful contrasts to traditional practices. This paper examines several years of experience using our alternative approach and suggests avenues for additional research.

- Description:
- Simulation activities have been used in teaching various topics in political science. Most literature on this methodology focuses on elaborate, time consuming activities. This article examines the creation and use of a one-session budget balancing simulation exercise. The experience with this simulation suggests that it is a useful and practical teaching tool.

- Description:
- Rationale, aims and objectives:
A valid tool to measure clinical competency early in medical school could identify
students who may require special educational attention. The overall aim is to assess the
relationship between students’ scores on an objective structured clinical examination
(OSCE) given in the second year of medical school and their subsequent performance on
Step 2 of the United States Medical Licensing Examination (USMLE Step 2).
Methods:
Participants were 390 second-year medical students participating in a required OSCE;
complete data (Medical College Admission Test, OSCE, USMLE Step 1 and Step 2
scores) were available for 340 students (87%). Univariate correlations and linear
regression analyses were performed.
Results:
Total OSCE score was moderately correlated with USMLE Step 2 score (r = 0.395, P <
0.001), as were two skills subscores of the OSCE, differential diagnosis (r = 0.343, P<
0.001) and identification of abnormality (r = 0.322, P < 0.001). In linear regression
analysis, neither OSCE total score nor any of the subscores independently predicted Step
2 scores; only Step 1 score (β = 0.687, P < 0.001) and female sex (β= 0.152, P < 0.001)
remained independent correlates of Step 2 score.
Conclusion:
OSCEs early in medical school can be useful in the early assessment of clinical
competence.

- Description:
- This article explores the process through which teachers go as they engage in teacher research that attempts to answer ‘burning questions’ about their practice. It reports on the experiences of 45 in-service teachers enrolled in an MA in Education program as they develop an inquiry ethic while engaging in research projects that require them to collect and analyze data, interact with instructors and peers, engage in dialogue surrounding inquiry, and draw conclusions from their data collection and analysis during semester-long course. Based on data collected over a two-year period, the authors attempt to pose a framework for the development of such an ethic, positing the dimensions of the stance that teacher researchers demonstrate as they begin to view themselves as part of the ongoing dialogue between theory and practice. It further describes the nature of each dimension as well as the products of the teacher research projects.

- Description:
- Purpose - The purpose of this article is to present a series of reflections on future scenarios
distributed to Taiga Forum participants in March 2006.
Design/methodology approach - Permission was obtained to reprint the scenarios, and select
national library leaders, seasoned professionals and mid-career librarians were invited to respond to
these scenarios.
Findings - Taiga scenarios focus on broad areas - internal organizational structures, advances in
information technology, changing user expectations. Local engagement with these scenarios will help
staff prepare for the future. Scenarios lend themselves to a variety of uses, including in-service
training, staff development, team building. Scenario planning can easily be tailored to the specific
needs of an institution.
Originality/value - The Taiga Forum was an invitation-only event. Broader dissemination of the
scenarios provides others not only with the opportunity to move beyond their borders in technical
services, public services, collection development, or information technology, and transcend the
traditional library organization, but also with the opportunity to develop new solutions.

- Description:
- This paper provides the first comprehensive empirical analysis of agricultural trade using a gravity model. The data set covers bilateral trade in agricultural goods for 152 countries over the periods 1990–1993 and 1999–2002. The estimations support claims that protectionism and distortive subsidies to agriculture remain widespread among industrialised nations, which are shown to import fewer and export more agricultural products than expected given other economic, political and geographic determinants of trade. However, some developing regions which are often thought to be the main victims of industrial-country protectionism are also found to be relatively closed to agricultural trade.
