Optimal unconditional critical regions for 2 2 2 multinomial trials

Analysing a 2 2 2 table is one of the most frequent problems in applied research (particularly in epidemiology). When the table arises from a 2 2 2 multinomial trial (or the case of double dichotomy), the appropriate test for independence is an unconditional one, like those of Barnard (1947), which, although they date from a long time ago, have not been developed (because of computational problems) until the last ten years. Among the different possible versions, the optimal (Martín Andrés & Tapia Garcia, 1999) is Barnard's original one, but the calculation time (even today) is excessive. This paper offers critical region tables for that version, which behave well compared to those of Shuster (1992). The tables are of particular use for researchers wishing to obtain significant results for very small sample sizes (N h 50).     

Historical Sociology and Secularisation: The Political Use of ‘Culturalised Religion’ by the Radical Right in Spain

The critique of the theory of secularisation has favoured the emergence of a series of concepts for the analysis of contemporary socio-religious transformations, such as ‘culturalised religion’. These categories constitute, in turn, an opportunity to rethink the process of secularisation from the perspective of historical sociology. Against this background, this article carries out a theoretical analysis of the ambiguities of secularisation in Spain from which a cultural approach to religion (‘culturalised religion’) emerges and its potential connection to the expansion of the radical right-wing party Vox, which became the third-largest party in Spain's parliament in the 2019 national election. After analyzing this interrelation between ‘culturalised religion’ and the radical right on the basis of statistical sources, discourse analysis and bibliographical sources, the article concludes by stressing the importance of historical sociology for understanding phenomena like ‘culturalised religion’, which take us out of the binomial logic that has marked part of the interpretation of secularisation (revival of religions vs decline of the religious) and introduce us into the multiple interactions between the historical past and sociological reality.     

New HEAVY Models for Fat-Tailed Realized Covariances and Returns

ABSTRACT

We develop a new score-driven model for the joint dynamics of fat-tailed realized covariance matrix observations and daily returns. The score dynamics for the unobserved true covariance matrix are robust to outliers and incidental large observations in both types of data by assuming a matrix-F distribution for the realized covariance measures and a multivariate Student's t distribution for the daily returns. The filter for the unknown covariance matrix has a computationally efficient matrix formulation, which proves beneficial for estimation and simulation purposes. We formulate parameter restrictions for stationarity and positive definiteness. Our simulation study shows that the new model is able to deal with high-dimensional settings (50 or more) and captures unobserved volatility dynamics even if the model is misspecified. We provide an empirical application to daily equity returns and realized covariance matrices up to 30 dimensions. The model statistically and economically outperforms competing multivariate volatility models out-of-sample. Supplementary materials for this article are available online.     

2009 New England Technical Services Librarians (NETSL) Spring Conference: Working the Cataloging Landscape: Fishing,Mining, and Harvesting

Abstract

Rachel Fleming and Kristin Calvert of Western Carolina University discuss their study of interlibrary loan borrowing requests in the three years surrounding a journal cancellation project. Noting that the impact of such a cancellation on interlibrary loan has not been studied since the 1990s, they examine numerous facets of requests for cancelled and non-cancelled journals, including request per journal, year of article requested, and request history for newly cancelled journals. Though journal cancellations resulted in a 2 percent increase in interlibrary loan requests, this number proved so small that Calvert and Fleming judged that their cancellations caused no undue effects.     

Reports of Conferences,Institutes, and Seminars

Abstract

This column covers several conference sessions from the 14th annual Electronic Resources & Libraries Conference, providing guidance on how to navigate ebook duplication, improving documentation and workflows, implementing OpenAthens, and experiences with Project SILLVR (Streaming Interlibrary Loan Video Resources)and knowledge bases and related tools (KBART) automation. There is also a report from IFLA’s SIG Library Publishing Mid-Term meeting, which was an ideological meeting in nature, discussing community building, resource sharing, and status updates. A report from the 2018 Charleston Conference is also included.
