The Pavement ME transverse joint faulting model incorporates mechanistic theories that predict development of joint faulting in jointed plain concrete pavements (JPCP). The model is calibrated using the Long-Term Pavement Performance database. However, the Mechanistic-Empirical Pavement Design Guide (MEPDG) encourages transportation agencies, such as state departments of transportation, to perform local calibrations of the faulting model included in Pavement ME. Model calibration is a complicated and effort-intensive process that requires high-quality pavement design and performance data. Pavement management data—which is collected regularly and in large amounts—may present higher variability than is desired for faulting performance model calibration. The MEPDG performance prediction models predict pavement distresses with 50% reliability. JPCP are usually designed for high levels of faulting reliability to reduce likelihood of excessive faulting. For design, improving the faulting reliability model is as important as improving the faulting prediction model. This paper proposes a calibration of the Pavement ME reliability model using pavement management system (PMS) data. It illustrates the proposed approach using PMS data from Pennsylvania Department of Transportation. Results show an increase in accuracy for faulting predictions using the new reliability model with various design characteristics. Moreover, the new reliability model allows design of JPCP considering higher levels of traffic because of the less conservative predictions.

Different Characteristics

This is a reprint from Vol 1, no 1, which has not previously been available in electronic format.The analysis and understanding of the conduct and performance of an industry begins with a study of its structure. However, before analysing an industry's structure it is necessary to define the industry and identify its size, scope and scale to establish its true economic contribution. This paper discusses the size and scope of the Australian building and construction industry, firstly froma traditional industry economics approach by firm size and business characteristics using data fron three construction industry surveys done over 15 years by the ABS. Secondly, data from an industry 'cluster' perspective is shown. The objective of the paper is to compare the differences found in industry size and scope in the structure-conduct-performance approach and the alternative industry cluster approach. Each model reveals different characteristics of the industry. The conclusion finds that the building and construction industry is a case where the traditional structure-conduct-performance model cannot be easily applied.

Performance Variations

Because of inconsistent empirical evidence, the membership-performance model pervasive in strategic group analysis is re-examined. We propose that individualfirm capabilities, which reflect capacity to implement or change strategy, moderate the effect of members' shared strategy characteristics on performance. Controlling for market structure, we defined two strategic groups based on common strategy characteristics among 55 manufacturing firms. We found significant differences in performance and capabilities within each group. There was also evidence of a significant correlation between capabilities and performance within each group. We conclude that effects offirms' capabilities should be accountedfor to increase the explanatory power of strategic groups in competitive performance.

This study aims to describe Reyog Ponorogo from the historical aspect, the negative stigma that has accompanied its development, and local wisdom that spreads to all its components. This problem is studied using a qualitative approach. Data collection techniques using in-depth interviews with data collection tools is the researcher himself as a key instrument. The data analysis technique used in this research is descriptive analytical with the process of data reduction, data presentation, and conclusion drawing. The findings of this study are as follows; (1) Reyog Obyog is an important and inseparable part of Reyog Ponorogo. In fact, it is very possible that Reyog Obyog is the origin of the Reyog Ponorogo which has developed and is known to the public today; (2) Reyog Obyog performance model which tends to be free, not bound by standards, is performed in the audience and is predominantly filled with entertainment, in its development various negative stigmas have emerged in the community, namely eroticism, drunkenness, and mystical performance rituals; (3) The Reyog Obyog has a great value in the form of a noble life guidance which is strategic enough to be used as a medium for building civilization.

AbstractHabanera, one of the most famous songs in Opera Carmen, tells the love life of Carmen as the main role. Interestingly, the song Habanera was sung by an Indonesian mezzo-soprano singer from Bali, Heny Janawati, who has perform the Opera Carmen while singing in Europe and Indonesia with different interpretations and performance of song Habanera. The purpose of this study was to analyze the interpretation and performance form of the Habanera Opera Carmen song when it was performed in Jakarta in 2016 in order to become a knowledge. This research process used qualitative methods. The data in this study were obtained through observation, interviews, and documentations. Data analysis techniques used data reduction, data presentation, and data inference. As for the data validity test used triangulation. The results of this study indicate that Heny Janawati has characteristics to interpret this song through out the structure, tempo, dynamics, and intonation of this song. That she present in Opera Carmen are more modern from it's europe counterpart, which in Europe its characteristics, number of accompaniments, dimensions of the setting, lighting and wardrobe are more traditional.
