The national survey, conducted for all art museums in the United States and Canada, resulted in 252 questionnaires, of which
166 were computer-user museums with acceptable questionnaires. The institutions using computers averaged 2.2 million in budget and had a median membership level of 860. Museums were divided in small, medium, and large budget categories by the budget ranges of2.2 million in budget
and had a median membership level of 860. Museums were divided in small, medium, and large budget categories by the budget
ranges of 0-210,000, 211-817,000, and211-817,000, and 818,000+. 相似文献

The distributions of citations L, two- (IF2) and five-year impact factors (IF5), and citation half-lives λ of journals published in different selected countries are analyzed using Langmuir-type relation: yn = y0 {1 ? αKn/(1 + Kn)}, where yn denotes Ln, IF2 n or IF5 n of n-ranked journal, y0 is the value of yn when journal rank n = 0, α is an empirical effectiveness parameter, and K is the Langmuir constant. It was found that: (1) the general features of the distribution of Ln, IF2 n or IF5 n of the journals published in different individual countries are similar to the results obtained before by the author from the analysis of the citation distribution data of papers of individual authors (K. Sangwal, Journal of Informetrics 7 (2013) 36–49), (2) in contrast to the theoretically expected value of the effectiveness parameter α = 1, the calculated values of α > 1 for journals published in different countries, (3) the trends of the distribution of cited half-lives λn of journals differ from those of Ln, IF2 n and IF5 n data for different countries, and show one, two or three linear regions, the longest linear regions with low slopes are observed in the case of countries publishing relatively high number of journals, and (4) the product of the Langmuir constant K and the number N of journals for the processes of citations and two- and five-year impact factors of journals published in different countries is constant for a process. The results suggest that: (1) the values of α > 1 are associated with a process that retards the generation of items (i.e. citations or impact factors), the difference ( α ? 1) being related to the dissemination of contents of the journals published by a country, and (2) the constancy of KN is related to the publication potential of a country. 相似文献

We develop efficient dynamic programming algorithms for pattern matching with general gaps and character classes. We consider
patterns of the form p
0
g( a
0, b
0) p
1
g( a
1, b
1)… p
m−1, where p
i
⊂ Σ, Σ is some finite alphabet, and g( a
i
, b
i
) denotes a gap of length a
i
… b
i
between symbols p
i
and p
i+1. The text symbol t
j
matches p
i
iff t
j
∈ p
i
. Moreover, we require that if p
i
matches t
j
, then p
i+1 should match one of the text symbols Either or both of a
i
and b
i
can be negative. We also consider transposition invariant matching, i.e., the matching condition becomes t
j
∈ p
i
+ τ, for some constant τ determined by the algorithms. We give algorithms that have efficient average and worst case running times. The algorithms
have important applications in music information retrieval and computational biology. We give experimental results showing
that the algorithms work well in practice. 相似文献

Abstract This article introduces the Partnership for Shared Book Collections, a federation of monograph shared print programs. Collaboration of programs at the network level allows for: -
Reducing the cost of retaining the scholarly record through shared distribution of commitments; -
De-duplicating efforts; -
Developing and promoting evidence-based best practices; -
Increasing the effectiveness of communication with end-users and funders; -
Tackling large-scale projects and research that are out of reach for individual shared print programs. This shared stewardship of collection is critical as local resources are depleted due to the COVID-19 pandemic and access to print for digitization increases. 相似文献

This article provides a summary of and commentary on ‘A Lovely Kind of Madness: Small and Independent Publishing in Australia’,
an unpublished report by Kate Freeth, commissioned by the Small Press Underground Networking Community (SPUNC), the representative
body for small and independent publishers in Australia, and released in November 2007. Freeth’s 14,000 word report constitutes
the most detailed and comprehensive study of Australian small and independent publishing since the second volume of Michael
Denholm’s Small Press Publishing in Australia (1991) and provides much primary material for policy makers, scholars, and people working in and around the publishing industry.

Five ratios RH, RT, SH, ST and SZ derived from the three-part division of a set of sources in h-core, h-tail and uncited sources are defined. Dynamic changes in the three independent ratios RH, SH and SZ are studied for six selected topics. Data about these topics are obtained from the Web of Science for scientific papers and Derwent Innovations Index for technical patents. It is observed that all RH- and SH-values decrease when the time span widens, while SZ stays the same or increases; and that all RH- and SH-values for papers are larger than the corresponding values for patents. The shifted Lotka distribution is used in a theoretical interpretation of these empirical phenomena. 相似文献

Conclusion Protecting a merchandising program by the given means of Law means safeguarding substantial investment for obtaining a certain
Merchandising Property. Therefore protection should be found at a very early stage and has to be maintained with great care
to avoid later conflicts and loss of money. Before starting a merchandising program four steps should be resolved:
1. |
Find out what you want to merchandise. What has the potential?
|
2. |
Find out who is the owner of that intellectual property.
|
3. |
Protect the property against piracy.
|
4. |
Safeguard your expenses by solid contracts.
