Technical pre-study for the ExMS project

This report aims to give an overview of software and hardware platforms available now or in the near future for building a prototype of an ExMS application (for an overview of the ExMS project, see Appendix). The report also gives an overview of the different technologies for building third-party mobile client software applications that are in use today. The report is composed of three sections. The first section is a general discussion on mobile client software and the different technologies that can be used to develop third-party mobile client software. The next section continues with a specific discussion on ExMS and answers the following questions: What is the general architecture of the ExMS application? What alternatives exist for implementing the ExMS prototype? The final section of the report is a recommendation of hardware and software platform for building the ExMS prototype

The impact of minimum wages on employment in a low income country : an evaluation using the difference-differences approach

Unlike the well-developed literature on the employment impact of the minimum wage in industrial nations, very little is known about minimum wage effects in low income countries. Minimum wages increased sharply in Indonesia between 1990 and 1996 and by more in some provinces than in others. Following Card and Krueger (1994) the authors exploit the large geographic variation in the rate of increase and compare changes in employment in the clothing, textile, footwear, and leather industries on either side of the Jakarta-West Java border. They use household level labor market data to establish compliance with the legislation. They obtain matched difference-in-difference estimates of the employment impact using a census of all large and medium-size firms in the clothing, textile, leather, and footwear industries. The authors find some evidence of a negative employment impact for small, domestic firms but no employment impact for large firms, foreign or domestic.Environmental Economics&Policies,Banks&Banking Reform,Public Health Promotion,Labor Policies,Municipal Financial Management,Environmental Economics&Policies,Banks&Banking Reform,Child Labor,Municipal Financial Management,Health Monitoring&Evaluation

Extensible Technology-Agnostic Runtime Verification

With numerous specialised technologies available to industry, it has become increasingly frequent for computer systems to be composed of heterogeneous components built over, and using, different technologies and languages. While this enables developers to use the appropriate technologies for specific contexts, it becomes more challenging to ensure the correctness of the overall system. In this paper we propose a framework to enable extensible technology agnostic runtime verification and we present an extension of polyLarva, a runtime-verification tool able to handle the monitoring of heterogeneous-component systems. The approach is then applied to a case study of a component-based artefact using different technologies, namely C and Java.Comment: In Proceedings FESCA 2013, arXiv:1302.478

Globalization's impact on compliance with labor standards

In an effort to shed some light on the larger question of labor standardsvand globalization, we seek to examine compliance with minimum wage legislation in Indonesia. Indonesia is an ideal case study because the govern ment made minimum wages a central component of its labor market policies in the 1990s. During this time, minimum wages quadrupled in nominal terms and doubled in real terms. In this paper we estimate the relationship between international competition and compliance with the statutory minimum wage in Indonesia. We identify firms facing international competition with two plant-level indica tors. First, we use the plant's export orientation as one measure of international competition. Second, we use the plant's foreign ownership as another measure of international competition. Critics claim that foreign firms are exploiting foreign workers, although our research on developing countries has shown that foreign enterprises are more likely to pay higher wages. This framework provides a direct test of the relationship between meas ures of globalization and labor standards, as defined by compliance with the regional minimum wage.globalization; minimum wages; foreign investment; corporate social responsibility

The Demand for Beef in Indonesia: Implications for Australian Agribusiness

Meat consumption and socio-demographic data from the 1990, 1993 and 1996 SUSENAS Household Food Expenditure and Consumption Surveys were employed to estimate the demand for meats in Indonesia. The focus was on the Provinces of DKI Jakarta and West Java where about one-fourth of the Indonesian population reside. Statistical and econometric procedures were used to aggregate the 16 meat types recorded in the SUSENAS into four Meat Groups. They were then used to estimate the Linear Approximation of the Almost Ideal Demand System (LA/AIDS) model, taking into account zero observations and the restrictions on budget shares. The demand for Meat Group 1 (with the dominant meat, beef) is income-inelastic, whereas for Meat Group 2 (with the dominant meat, commercial and native chicken) it is income-elastic. These two groups comprise nearly 95 per cent of all meat purchases. The estimated own-price elasticity of the beef group is -0.92, while that for the chicken group is -1.09. The cross-price elasticities indicate that all the meat groups are substitute goods, as expected. The results suggest that the current focus of the Indonesian government on strengthening the domestic poultry industry is well placed, as the demand for chicken is likely to respond more quickly to income growth than the demand for beef. Further, consumers seem more likely to adapt their chicken consumption patterns to price changes than they do for beef. However, these differences are relatively minor and there is still a major opportunity for Australian agribusiness firms in the cattle and beef sectors to take advantage of the projected rapid growth in Indonesian beef demand.beef demand, almost ideal demand system, commodity aggregation, Demand and Price Analysis, Food Consumption/Nutrition/Food Safety, Livestock Production/Industries,

RACOFI: A Rule-Applying Collaborative Filtering System

In this paper we give an overview of the RACOFI (Rule-Applying Collaborative Filtering) multidimensional rating system and its related technologies. This will be exemplified with RACOFI Music, an implemented collaboration agent that assists on-line users in the rating and recommendation of audio (Learning) Objects. It lets users rate contemporary Canadian music in the five dimensions of impression, lyrics, music, originality, and production. The collaborative filtering algorithms STI Pearson, STIN2, and the Per Item Average algorithms are then employed together with RuleML-based rules to recommend music objects that best match user queries. RACOFI has been on-line since August 2003 at http://racofi.elg.ca.
