    Using Domain Ontology for Service Replacement Tasks: An Empirical Evaluation

    Get PDF
    Organizations increasingly use information technology (IT) to integrate their business processes into the processes of their suppliers, customers, and other third parties. An important IT approach is the realization of composite services that organize elementary software services under a shared workflow. Any failure of an elementary service can severely impact the process. The failed service must be examined and, ultimately, be replaced. In solving that task, the process designer must consider the quality-of-service (QoS) of the process. However, the heterogeneity of service descriptions puts the burden on the designer. This research empirically evaluates how designers can use a domain ontology, namely the QoS aggregation ontology, for the replacement task. We report on a laboratory experiment to compare the effectiveness and efficiency of using the ontology vis-Ă -vis an aggregation table. The results provide evidence for the usefulness of the domain ontology that specifies problem-solving knowledge required for a time-critical task

    ESG and corporate financial performance: evidence from JSE listed firms

    Get PDF
    Business is an incredible social construct of the world, consisting of firms that are part of and arise from society. However, businesses have come under increasing scrutiny from internal and external stakeholders over sustainable business practices. A sustainable business model creates a balance between integrity, equity and financial prosperity, the so-called triple-bottom-line. Environmental, social and governance issues (ESG) have become the modern-day proxy for sustainable business practices. The relationship between sustainable business practices and corporate financial performance is a relatively new but prominent area of research in practice and academia in South Africa. This study explores the relationship between ESG disclosure performance and the corresponding corporate financial performance (CFP) for 70 sampled firms listed on the Johannesburg Stock Exchange (JSE) between the periods 2011 and 2019. In line with international and South African research, ESG in its composite and disaggregated form was considered against a select number of CFP metrics. Select accounting-, market- and qualitybased CFP metrics were considered. Quantitative research methods were employed, using panel regression models to investigate the ESG-CFP relationship where ESG was the independent variable while the CFP metrics were individually considered as the dependent variables. All CFP data was obtained from Bloomberg and Bloomberg's proprietary ESG scores were used. This study finds a statistically significant negative relationship between ESG and the selected CFP metrics. Upon disaggregating the ESG scores, it was evident that the E- and S-scores were also significantly and negatively related to the CFP metrics whilst the G-score was positively related to CFP, but it was not statistically significant. The empirical evidence suggests that over a nine-year investment horizon, higher ESG disclosure performance detracts from firm fundamental and market performance. Further interpretation of the results in conjunction with the literature may suggest that ESG ought to be seen as an insurance policy against excessive underperformance during volatile periods and not a CFP enhancer. Therefore, being “over-insured with ESG” may lead to underperformance

    The past, present, and probable future for community banks

    We review how deregulation, technological advance, and increased competitive rivalry have affected the size and health of the U.S. community banking sector and the quality and availability of banking products and services. We then develop a simple theoretical framework for analyzing how these changes have affected the competitive viability of community banks. Empirical evidence presented in this paper is consistent with the model's prediction that regulatory and technological change has exposed community banks to intensified competition on the one hand, but on the other hand has left well-managed community banks with a potentially exploitable strategic position in the industry. We also offer an analysis of how the number and distribution of community banks may change in the future.Community banks
