Process-Oriented Collective Operations

Distributing process-oriented programs across a cluster of machines requires careful attention to the effects of network latency. The MPI standard, widely used for cluster computation, defines a number of collective operations: efficient, reusable algorithms for performing operations among a group of machines in the cluster. In this paper, we describe our techniques for implementing MPI communication patterns in process-oriented languages, and how we have used them to implement collective operations in PyCSP and occam-pi on top of an asynchronous messaging framework. We show how to make use of collective operations in distributed processoriented applications. We also show how the process-oriented model can be used to increase concurrency in existing collective operation algorithms

Toward the Sustainable Development of Operations: Improving Energy Efficiency as a Means to Sustainability as Practice

Addressing the challenges of sustainable development demands companies to understand the “how” to actualize sustainability-related objectives and cultivating conditions that encourage practicing sustainability. It also demands companies to structure their operations around less costly economic processes while maintaining the efficient use of resources and standards for workers’ well-being at the operational level. Given companies’ reliance on and increasing demand for energy-dependent operational processes to produce and transport products and services, sharp upward pressure on energy bills for industries directly exposed to rising prices, and shortages and supply chain disruptions, requires companies to make unprecedented changes. Therefore, as the need to use alternative energy sources has increased, the importance of accelerating improvements in energy efficiency in operations as an energy source itself has been increasingly acknowledged.In response, this thesis seeks to expand current understandings of improving energy efficiency in operations in order to facilitate sustainability as practice, namely by embedding the concept of sustainable development into the theoretical framework of operations management. First, improving energy efficiency is analyzed as a firm-based practice that results in the actualization of corporate-level objectives for energy efficiency in operations by utilizing resources and influencing individual and/or collective action. Second, operations strategy is the analytical construct used to analyze the strategic–operational alignment of the resources needed to allow engaging in and replicating such an improvement-oriented process constructed and enacted by multiple individuals within and across organizational levels. Third and last, the thesis focuses on development via changes in individual and collective actions and understandings toward promoting sustainability as practice by building up people’s skills and competencies.Drawing from findings in the five appended papers, the thesis first characterizes the improvement of energy efficiency in operations as a practice. \ua0Second, the thesis analyzes strategic–operational alignment in organizations by investigating the improvement of energy efficiency in operations as a practice in relation to organizations’ strategic intentions for sustainability as well as existing operations strategy. The results showcase examples of the bidirectional perspective on synergy between operations management and energy management. Last, whereas energy efficiency indeed requires focusing on the improvement process, the thesis argues that it also sustains such improvement and creates a constellation of practices that result in changes in people’s behavior. Achieving such continuity creates a context for practicing sustainability and gaining leverage to accomplish the sustainable development of operations

A Typology of Mass Services: The Role of Service Delivery and Consumption Purpose In Classifying Service Experiences

Purpose — The purpose of this paper is to provide services marketers with a deeper understanding of the elements that characterize mass services. The paper shows that many studies have been conducted within the context of professional and retail services, knowledge of mass service contexts is limited despite the growth of services within this context. Design/methodology/approach — This paper provides a conceptual overview of mass services and develops a typology for mass services based on an extensive review of the services literature. Specifically, the typology developed classifies mass services on the basis of service delivery and purpose. The typology forwarded, therefore, classifies mass services using a two-by-two framework with individual and collective mass services classified as either utilitarian or hedonic in nature. Findings — The typology found in this paper provides a practical insight into the characteristics of services falling into the classification of mass services. The value of the classification is that managers can better understand the unique aspects of mass services, thus, allowing for a better utilization of limited resources. Moreover, the paper provides insights into a service classification that has received limited research emphasis, yet, is attracting increasing industry attention. Originality/value — This paper provides academics and practitioners with a framework that has both tactical and strategic implications. These implications include enhancing the customer experience and thus customer retention, resource management, employee training and service management. Given that such a framework has not been forwarded in the literature, the typology presented in the current paper makes an original contribution to the literature

Learning from the Success of MPI

The Message Passing Interface (MPI) has been extremely successful as a portable way to program high-performance parallel computers. This success has occurred in spite of the view of many that message passing is difficult and that other approaches, including automatic parallelization and directive-based parallelism, are easier to use. This paper argues that MPI has succeeded because it addresses all of the important issues in providing a parallel programming model.Comment: 12 pages, 1 figur

Recent Developments in Employment Relations in the Philippines

We seek to describe recent developments in employment relations in the Philippines, placing these developments in the contexts of the distinctive elements of the Philippine social/political/industrial relations systems as well as the ongoing trade-based and functional integration of international markets and the recent regional economic crisis. We find that, while some firms are pursuing functional flexibility and more cooperative employment relations, the logic of competition has primarily induced firms to adopt practices that promote numerical flexibility such that a core-periphery workforce is created. We argue that the labor movement in the Philippines has been hampered in its efforts to effectively counter employer strategies by its low density, its fragmentation, and an unfavorable public policy environment; Philippine labor unions have, however, made some recent gains in organizing and inter-union coordination. We also argue that governments, both national and regional, have not done enough to counteract the negative effects of market integration on workers nor to evolve the Philippines into a higher value-added exporter

Understanding Entrepreneurship Process and Growth in Emerging Business Ventures under Market Socialism in China

Objectives: This paper aims to provide an insightful view of the entrepreneurial process and growth in different types of Chinese entrepreneurial enterprises under market socialism in China. This issue is explored by examining the organisational characteristics of three emerging business ventures under market reforms and institutional changes. It addresses the interactive effect of key contingency factors in entrepreneurship process and explains its impact on growth or failure outcomes in a particular ‘China type’ of market economy. Prior work: China’s hybrid economic system represents a mixed political economy with both socialist and capitalist characteristics (Lichtenstein, 1992; Morphy et al, 1992; Opper, 2001). Despite a growing body of research on Chinese small business practices alongside the economic reforms (Shen, 1994; Child, 1994; Naughton, 1994; Schlevogt, 2001; Warner, 2004; Yang, 2007; Kshetri, 2007; Yang and Li, 2008), more empirical studies are required to provide a critical insight into the emerging business practices. This research adopts a contingency model of entrepreneurship(Wickham, 2006) to examine entrepreneurship process and growth in different types of business venture. It reveals the interactive relationships among key variables such as strategy, ownership, culture and management process. Approaches: This research is undertaken through the empirical analysis of three case study companies in the textile industry. This fieldwork was conducted in 2006 and 2009 respectively. Multiple sources of data were collected including 21 open-ended interviews of owners and key managers in three case study companies. Results: The study offers an explanation on how entrepreneurship takes different forms and features in different organisational contexts. Empirical evidence supports four hypotheses: (1) The type of ownership is a key contingent factor that moderates particular entrepreneurial outcomes. (2) Leadership and knowledge accumulation capability are critical factors in learning process, significantly affecting the strategic choices in either high value or low value added products strategy. (3) The broadening of product portfolios and increased production capacity will improve survival chances and increase the likelihood of firm growth. (4) Management capability and consistency have greater impact on the outcome of entrepreneurship process than the resource and strategy factors. Implications: The findings have significant implications for a conceptual understanding of Chinese entrepreneurship dynamics. It addresses important considerations on government policy making and promotion strategies for entrepreneurship development in different forms of business venture. Value: The textile sector has pioneered the government reforms in restructuring and creating entrepreneurial enterprises. It offers a perfect case for assessing the entrepreneurship processes in a rapidly changing market environment. It emphasizes the important ownership effect on entrepreneurial outcomes. Drawing upon Wickham’s contingency model of entrepreneurship, it provides an improved understanding of this concept under particular circumstance and different contexts

On Agent-Based Software Engineering

Agent-based computing represents an exciting new synthesis both for Artificial Intelligence (AI) and, more generally, Computer Science. It has the potential to significantly improve the theory and the practice of modeling, designing, and implementing computer systems. Yet, to date, there has been little systematic analysis of what makes the agent-based approach such an appealing and powerful computational model. Moreover, even less effort has been devoted to discussing the inherent disadvantages that stem from adopting an agent-oriented view. Here both sets of issues are explored. The standpoint of this analysis is the role of agent-based software in solving complex, real-world problems. In particular, it will be argued that the development of robust and scalable software systems requires autonomous agents that can complete their objectives while situated in a dynamic and uncertain environment, that can engage in rich, high-level social interactions, and that can operate within flexible organisational structures
