The merits of using citationâbased journal weighting schemes to measure research performance in economics: The case of New Zealand
In this study we test various citationâbased journal weighting schemes, especially those based on the Liebowitz and Palmer methodology, as to their suitability for use in a nationwide research funding model. Using data generated by New Zealandâs academic economists, we compare the performance of departments, and individuals, under each of our selected schemes; and we then proceed to contrast these results with those generated by direct citation counts. Our findings suggest that if all citations are deemed to be of equal value, then schemes based on the Liebowitz and Palmer methodology yield problematic outcomes. We also demonstrate that even between weighting schemes based on a common methodology, major differences are found to exist in departmental and individual outcomes
EVALUATION OF THE UTILITY OF LIEBOWITZ SOCIAL ANXIETY SCALE AND BARRATT IMPULSIVENESS SCALE IN THE DIAGNOSIS OF SOCIAL ANXIETY, IMPULSIVITY AND DEPRESSION
Background: Often mental disorders are serious problems concerning psychological well-being. They require comprehensive
and specialized psychiatric and psychological help, but there are no public methods of controlling your mental state. The aim of
study was the evaluation of the utility of Liebowitz Social Anxiety Scale and Barratt Impulsiveness Scale in the diagnosis of social
anxiety, impulsivity and depression.
Subjects and methods: The study included 85 persons. The study group had 34 patients treated in an open ward of the
Department of Psychiatry and Psychotherapy of Medical University of Silesia in Katowice. The control group included 51 persons
without mental disorders. Three self-rating questionnaires were used: Beck Depression Inventory, Barratt Impulsiveness Scale and
Liebowitz Social Anxiety Scale. Statistica v10 Statsoft software was used for statistical analysis.
Results: The analyzed groups had significant differences in terms of Beck Scale (U Mann-Whitney test p=0.000001). Average
score in study group: 22.94±12.50; in control group: 7.15±6.44. Groups had significant differences in terms of Liebowitz Scale (U
test Mann-Whitney test, p=0.000164). Average score in the study group: 60.41± 30.30; in control group: 35.01±23.94. Groups had
significant differences in terms of Barratt Scale (t-student test p=0.000601). Average in study group: 66.35±9,49; in control group:
59.54±7.87. Significant positive correlation was observed between the results of Beck Scale and Liebowitz Scale (r=0.64465).
Correlation was not observed between the results of the Liebowitz and Barrat (r=0.12091 and Beck and Barrat (r=0.21482).
Conclusions: The intensity of the Liebowitz Social Anxiety Scale is directly proportional to the severity of depression according
to the Beck Depression Inventory. The degree of impulsivity by Barrat Impulsiveness Scale does not correlate with the level of
depression according to Beck Depression Inventory. The analyzed scales are relevant in the diagnosis of mental disorders
The Marianas Covenant Negotiations
In September 1969, the United States and the Congress of Micronesia\u27s Joint Committee on Future Status began their negotiations. This article will examine the negotiations which commenced in December 1972 and will concentrate on the three areas which were central points of discussion: the political relationships between the United States and the Northern Marianas; issues of economic development and assistance; and problems of land policy

The economics of copyright law: a stocktake of the literature
This article is a survey of publications by economists writing on
copyright law. It begins with a general overview of how economists analyse
these questions; the distinction is made between the economics of copying
and the economic aspects of copyright law as analysed in law and economics.
It then continues with sections on research on the effects of copying and
downloading and the effects of unauthorised use (âpiracyâ) and ends with an
overall evaluation of the economics of copyright in the light of recent technological
changes. Economists have always been, and still are, somewhat sceptical
about copyright and question what alternatives there are to it. On balance,
most accept the role of copyright law in the creative industries while urging
caution about its becoming too strong. And although European authorsâ rights
are different in legal terms from the Anglo-American copyright, the economic
analysis of these laws is essentially the same
A meta-analysis of pharmacotherapy for social anxiety disorder: an examination of efficacy, moderators, and mediators
INTRODUCTION: Social anxiety disorder (SAD) is among the most prevalent mental disorders, associated with impaired functioning and poor quality of life. Pharmacotherapy is the most widely utilized treatment option. The current study provides an updated meta-analytic review of the efficacy of pharmacotherapy and examines moderators and mediators of treatment efficacy. Areas Covered: A comprehensive search of the current literature yielded 52 randomized, pill placebo-controlled trials of pharmacotherapy for adults diagnosed with SAD. Data on potential mediators of treatment outcome were collected, as well as data necessary to calculate pooled correlation matrices to compute indirect effects. Expert Opinion: The overall effect size of pharmacotherapy for SAD is small to medium (Hedges' g = 0.41). Effect sizes were not moderated by age, sex, length of treatment, initial severity, risk of study bias, or publication year. Furthermore, reductions in symptoms mediated pharmacotherapy's effect on quality of life. Support was found for reverse mediation. Future directions may include sustained efforts to examine treatment mechanisms of pharmacotherapy using rigorous longitudinal methodology to better establish temporal precedence

Comparative effectiveness of drugs used to constrict the patent ductus arteriosus: a secondary analysis of the PDA-TOLERATE trial (NCT01958320).
ObjectiveTo evaluate the effectiveness of drugs used to constrict patent ductus arteriosus (PDA) in newbornsâ<â28 weeks.MethodsWe performed a secondary analysis of the multi-center PDA-TOLERATE trial (NCT01958320). Infants with moderate-to-large PDAs were randomized 1:1 at 8.1â±â2.1 days to either Drug treatment (nâ=â104) or Conservative management (nâ=â98). Drug treatments were assigned by center rather than within center (acetaminophen: 5 centers, 27 infants; ibuprofen: 7 centers, 38 infants; indomethacin: 7 centers, 39 infants).ResultsIndomethacin produced the greatest constriction (compared with spontaneous constriction during Conservative management): RR (95% CI)â=â3.21 (2.05-5.01)), followed by ibuprofenâ=â2.03 (1.05-3.91), and acetaminophenâ=â1.33 (0.55-3.24). The initial rate of acetaminophen-induced constriction was 27%. Infants with persistent moderate-to-large PDA after acetaminophen were treated with indomethacin. The final rate of constriction after acetaminophenâ±âindomethacin was 60% (similar to the rate in infants receiving indomethacin-alone (62%)).ConclusionIndomethacin was more effective than acetaminophen in producing ductus constriction
An Analysis of Using Expert Systems and Intelligent Agents for the Virtual Library Project at the Naval Surface Warfare Center-Carderock Division
The Virtual Library Project1 at the Naval Surface Warfare Center/Carderock Division (NSWC/CD) is being developed to facilitate the incorporation and use of library documents via the Internet. These documents typically relate to the design and manufacture of ships for the U.S. Navy Fleet. As such, the libraries will store documents that contain not only text but also images, graphs and design configurations. Because of the dynamic nature of digital documents, particularly those related to design, rapid and effective cataloging of these documents becomes challenging. We conducted a research study to analyze the use of expert systems and intelligent agents to support the function of cataloging digital documents. This chapter provides an overview of past research in the use of expert systems and intelligent agents for cataloging digital documents and discusses our recommendations based on NSWC/CDâs requirements

Buying commercial law: Choice of law, choice of forum, and network externalities
Copyright @ 2009 Bryan DruzinThis paper applies network effect theory to transnational commercial law, arguing that commercial parties selecting law through choice of law and choice of forum clauses can be likened to consumers selecting a product, and thus equally susceptible to the effects of network externalities. The number of âconsumersâ who subscribe to the same legal norms is analogous to the number of consumers who use a product. As the number of âconsumersâ increases, so too does the inherent value of selecting that jurisdiction, inducing even more parties to âpurchaseâ that body of law. This is a network effect. I argue that transnational commercial law is ideally calibrated so as to generate a network effect. This stems from the inherent nature of commerce. The discussion distinguishes between two kinds of externalities, direct and indirect network externalities, concluding that network systems that possess both kinds of network externalities (as is the case with law-selection decisions in commercial contracts), are the best candidates to produce a robust network effect. I then examine how the twin ingredients of fluid interaction and frequent choice present in commerce precipitate a network effect; expansive interaction places a higher premium on the need for synchronization, and frequent opportunities to select law in the contracts of fresh commercial relationships allow for an incremental drift towards a specific jurisdiction. The paper ultimately concludes that, as a result, network externalities indeed play an influential role in the ascension of particular jurisdictions over others in law-selection decisions, an important conclusion as it points to an unrecognized influence underpinning the current development of transnational commercial law
