The Frequent Items Problem in Online Streaming under Various Performance Measures

In this paper, we strengthen the competitive analysis results obtained for a fundamental online streaming problem, the Frequent Items Problem. Additionally, we contribute with a more detailed analysis of this problem, using alternative performance measures, supplementing the insight gained from competitive analysis. The results also contribute to the general study of performance measures for online algorithms. It has long been known that competitive analysis suffers from drawbacks in certain situations, and many alternative measures have been proposed. However, more systematic comparative studies of performance measures have been initiated recently, and we continue this work, using competitive analysis, relative interval analysis, and relative worst order analysis on the Frequent Items Problem.Comment: IMADA-preprint-c

Environmental proactivity and firms' performance: Mediation effect of competitive advantages in Spanish wineries

The main aim of this paper is to show the extent to which environmental proactivity is able to generate competitive advantages in a firm in order to improve their economic-financial performance by introducing the role of managerial perception into the analysis. This study focuses on Spanish wineries and their environmental practices and covers a total of 4598 wineries with a sample of 142 valid responses during the month of November 2015. The results can be summarized as follows. Firstly, there is positive environmental proactivity in terms of obtaining both cost-based and differentiation-based competitive advantages. Likewise, this proactivity has a positive impact on the manager’s perception of performance. Secondly, obtaining differentiation-based competitive advantages has a positive impact on the manager’s perception of performance although a negative impact on performance itself. There is, however, no significant evidence of the impact of cost-based competitive advantages on financial performance nor on the perception of performance itself, nor the impact of environmental proactivity on financial performance

PENGARUH TOTAL QUALITY MANAGEMENT DAN GREEN SUPPLY CHAIN MANAGEMENT TERHADAP CORPORATE SUSTAINABILITY PERFORMANCE DIMEDIASI COMPETITIVE ADVANTAGE

The aim of this research is to analyze the influence of total quality management and green supply chain management on corporate sustainability performance, mediated by competitive advantage directly or indirectly. This type of research is explanatory with sampling using a purposive sampling method. The number of samples that met the criteria was 102 respondents who were owners of Sanan tempeh chips SMEs in Malang city. This data was obtained through distributing questionnaires directly. The data analysis technique used in this research is Structural Equation Modeling (SEM) with the SmartPLS analysis tool. The research results show that total quality management has no significant effect on corporate sustainability performance, green supply chain management and competitive advantage have a significant effect on corporate sustainability performance, total quality management and green supply chain management have a significant effect on competitive advantage, Competitive advantage fully mediates the effect of green supply chain management on corporate sustainability performance, Competitive advantage partially mediates the influence of green supply chain management on corporate sustainability performance

Online Bounded Analysis

Though competitive analysis is often a very good tool for the analysis of online algorithms, sometimes it does not give any insight and sometimes it gives counter-intuitive results. Much work has gone into exploring other performance measures, in particular targeted at what seems to be the core problem with competitive analysis: the comparison of the performance of an online algorithm is made to a too powerful adversary. We consider a new approach to restricting the power of the adversary, by requiring that when judging a given online algorithm, the optimal offline algorithm must perform as well as the online algorithm, not just on the entire final request sequence, but also on any prefix of that sequence. This is limiting the adversary's usual advantage of being able to exploit that it knows the sequence is continuing beyond the current request. Through a collection of online problems, including machine scheduling, bin packing, dual bin packing, and seat reservation, we investigate the significance of this particular offline advantage.Comment: IMADA-preprint-c

Is an Environmental Management System able to influence environmental and competitive performance? The case of the Eco-Management and Audit Scheme (EMAS) in the European Union

The EMAS Regulation (Reg 761/01 EC) is an EU scheme for the implementation of an Environmental Management System (EMS) by any organization, implemented by the European Commission since the year 1993. The EMS has been originally proposed both by the European Commission and by ISO as the frontrunner of a series of policy tools that were conceived to enable companies to simultaneously pursue environmental objectives and competitive targets (in a synergetic way). Based on the unique dataset of the EVER project, this paper investigates whether or not an EMS implemented within the EMAS Regulation has an effect on firm performance both from an environmental and a competitive point of view. The econometric analysis shows a positive impact of well-designed environmental management system on environmental performance and, as a consequence, on technical and organizational innovations. Effects on other competitive variable as market performance, resource productivity and intangible asset are not strongly supported

HRM Practices in Insurance Companies: A Study of Indian and Multinational Companies

Competitive advantage of a company can be generated from human resources (HR) and company performance is influenced by a set of effective HRM practices. In this study, we intended to assess the HR practices in insurance companies. Primary data based on 218 respondents from four insurance companies (two multinational-7 branches and two Indian-7 branches) were analyzed to assess HR practices being practiced by insurance companies in India. Six factors from factor analysis were further analyzed. ‘Training and benefits’ was found highly in practice in the insurance companies. Further, ‘performance appraisal,’ ‘selection and socialization of employees,’ and ‘HR planning and recruitment’ were moderately practised in insurance companies. ‘Workforce diversity and contemporary HR practices’ and ‘competitive compensation’ were also practised to some extent. ANOVA results showed that Indian companies did not practise workforce diversity. Compensation practices were found more competitive or performance based in Multinational insurance companies than in Indian ones. The gender effect showed that only competitive compensation was perceived significantly differently by male and female employees/executives. Interactive effects were significant on workforce diversity and contemporary issues, training and benefits, and selection and socialization of employees.competitive compensation, multinational companies, performance appraisal, selection and socialization, training and benefits, workforce diversity
