Intervals for the assessment of measurement agreement: Similarities, differences, and consequences of incorrect interpretations

Several intervals have been proposed to quantify the agreement of two methods intended to measure the same quantity in the situation where only one measurement per method and subject is available. The limits of agreement are probably the most well-known among these intervals, which are all based on the differences between the two measurement methods. The different meanings of the intervals are not always properly recognized in applications. However, at least for small-to-moderate sample sizes, the differences will be substantial. This is illustrated both using the width of the intervals and on probabilistic scales related to the definitions of the intervals. In particular, for small-to-moderate sample sizes, it is shown that limits of agreement and prediction intervals should not be used to make statements about the distribution of the differences between the two measurement methods or about a plausible range for all future differences. Care should therefore be taken to ensure the correct choice of the interval for the intended interpretation.

Sexual orientation and sexual behavior patterns: Evaluation of agreement and variation in a cohort of male, African American drug users in Houston, TX

Background. Sexual orientation and sexual behavior among men have shown disagreement in past studies. The term "on the down low" has been adopted by many to describe "straight" identifying men who have sex with men but do not inform their primary female partner. Methods. This secondary analysis of data collected from the "DASH Project---A Hepatitis B Vaccine Model for HIV Vaccine Trial in Drug Users," assessed sexual behavior patterns among African American drug-using men over time. Using a screener questionnaire to determine sexual orientation and sexual behavior of the men, the study specifically evaluated "straight" identified men who have sex with women only (MSW) to determine what factors were associated with sexual behavior variation to include men during follow-up. The Fisher's Exact Test was used to evaluate the factors. Results. Variation of sexual behavior was highest among "bisexual" identified men followed by "gay" identified men. Fifteen of the original 593 "straight" and MSW men had sexual behavior variation to include men. In the analysis of "straight" and MSW men with variation in sexual behavior compared to those who did not, living on the streets, greater number of sexual partners, trading sex for drugs, and trading sex for money were associated with sexual behavior variation (all p-values <0.01). Conclusions. The factors were only associated when considering the interview when the variation occurred. The same factors at screening were not predictive of sexual behavior variation in the future. Environmental factors, such as living situation, appear to play a role in sexual behavior variations in "straight" and MSW men. ^ Keywords. sexual behavior, sexual orientation, Fisher's Exact Test^

Analysis of the prospects for updating the trade pillar of the European Union-Chile Association Agreement

The perception of the present state of trade relations with Chile is obscured by a lack of adequate understanding of its legal framework as well as of the policy behind it. This study attempts to clarify the present state of and future prospects for trade between the EU and Chile through an examination of previous agreements and the EU’s new approach to trade liberalisation. The authors agree with the large consensus existing on both the EU and Chilean sides regarding the efficacy of the Association Agreement, but note that any extension of an agreement with Chile should capture the spirit of older EU agreements rather than simply following the ‘NAFTA route’. The study also includes a comparative analysis between the EU-Chile agreement and current trade agreements being negotiated by the EU and Chile with third countries.

Analysis of the upcoming Modernisation of the Trade Pillar of the European Union-Mexico Global Agreement

Study for the EU Parliament co-authored by Rodrigo Polanco: The 1997 Global Agreement between the EC and its Member States and Mexico, together with the set of decisions taken in its framework, has been effective, and thus modifications of the agreement are mainly motivated by changes in the global landscape since it was first enacted. Therefore, broad considerations on how the European Union (EU) trade policy is shaped are extremely relevant for the upcoming negotiations with Mexico. In this context, the needs and expectations, both from the EU and Mexico, regarding any further agreements are examined, focusing in particular on areas beyond trade in goods and services such as procurement, investment, and regulatory cooperation. It is argued that the 'old' Association Agreements should be taken as models for any modifications, given their emphasis on EU-specific issues and their ability to accommodate the needs of Mexico in any deepened agreement.

Looking Toward the “New Era” Features and Background of the Japan-Thailand Economic Partnership Agreement

This paper examines Thai-Japanese relations through analysis of EPA. There are two questions. The first involves the features of JTEPA as an EPA. By scrutinizing the features of the EPA, we would like to approach the institutional framework of the “new era” which will be brought about by JTEPA. The second question is how did the governments of Thailand and Japan come to conclude JTEPA? By reviewing the focal points of the negotiations, we will describe the background of the formation and aims of JTEPA. Finally, we conclude that JTEPA is a culmination of the existing Thai-Japanese relations, and was built based upon the existing divergence of economic institutions. At the same time it upgrades the bilateral partnership to a framework for multilateral cooperation by considering assistance toward Cambodia, Laos and Myanmar and Vietnam. The author would like to emphasize that JTEPA was designed based on the idea of a further integration of CLMV and Thailand, an original member of ASEAN.

Re-thinking Argentina's labour and social security reform in the 1990s : agreement on competitive corporatism

This paper will analyze the Menem administration's social policy reforms during the 1990s. Neo-liberal reforms in Argentina are well-known both in the economy and in the social arena, but in the latter we can discern the presence of tripartite negotiations. The form of such negotiations, the type of agreements reached as a result, and the background to those agreements will be discussed. We also pay attention to the concept of competitive corporatism, which was established under the increase in market competition brought about by globalization.

Measuring fixed costs for firms' use of a free trade agreement : threshold regression approach

In this paper, by employing the threshold regression method, we estimate the average tariff equivalent of fixed costs for the use of a free trade agreement (FTA) among all existing FTAs in the world. It is estimated to be 3.2%. This global estimate serves as a reference rate in the evaluation of each FTA’s fixed costs.

Selection and utilization of the early harvest list : evidence from the Free Trade Agreement between China and Taiwan

In this paper, we conducted an empirical investigation into the determinants of FTA utilization in exports from Taiwan to China. To do this, we first estimated the selection equation to see what kinds of products are included in the early harvest list. As a result, we found that Taiwan includes products with a medium magnitude of benefits from tariff removal in the early harvest list. Taiwan also includes products for which ASEAN countries have better access to the China market. We then estimated the equation for the determinants of FTA utilization by introducing an inverse of the Mills ratio estimated in the selection equation. The findings are that, as usual, the FTA rates are more likely to be utilized for products with a larger tariff margin. In addition, some rules of origin are found to be relatively restrictive in terms of discouraging trade.

Some practical guidance for the computation of free trade agreement utilization rates

The literature on the use of free trade agreements (FTAs) has recently been growing because it is becoming more important to encourage the use of current FTAs than to increase the number of FTAs. In this paper, we discuss some practical issues in the computation of FTA utilization rates, which provide a useful measure to discover how much FTA schemes are used in trade. For example, compared with the use of customs data on FTA utilization in imports, when using certificates of origin data on FTA utilization in exports, there are several points about which we should be careful. Our practical guidance on the computation of FTA utilization rates will be helpful when computing such rates and in examining the determinants of those rates empirically.

Distributed orientation agreement in a group of robots

In this article, a method for the agreement of a set of robots on a common reference orientation based on a distributed consensus algorithm is described. It only needs that robots detect the relative positions of their neighbors and communicate with them. Two different consensus algorithms based on the exchange of information are proposed, tested and analyzed. Systematic experiments were carried out in simulation and with real robots in order to test the method. Experimental results show that the robots are able to agree on the reference orientation under certain conditions. Scalability with an increasing number of robots was tested successfully in simulation with up to 49 robots. Experiments with real robots succeeded proving that the proposed method works in reality.
