The Primacy of Space in Politics: Bargaining Rights,Freedom and Power in an İstanbul Neighborhood

This article explores and theorizes the ways in which urban space and political contestations are mapped onto each other. The ethnography illustrates the multifaceted transformations in a notoriously secularist neighborhood of ?stanbul, Te?vikiye, as it first turns into a high‐consumption locality in the post‐1980s, then into a high‐conflict urban space in the new millennium on the arrival of Muslim high‐spenders, particularly headscarved women. Aiming to fill the gap left by the absence of spatial analysis from political science and political sociology, I argue that the urban neighborhood becomes central for political contestation when both government and opposition fail to protect and secure liberties and rights. Now that devout Muslims are integrated into highly contested urban sites and share bourgeois lifestyles, ordinary people act in defense of their ‘sphere’ of freedom and privacy. This new territoriality is largely symptomatic of increasing fears of losing freedom, privacy and social status. This spatial defensiveness is reinforced by people's decreasing trust in, and increasing demands from, the state for the protection and security of their rights and liberties. My overarching argument is that exclusive attention to the bipolar clash between devout Muslims and secularists under the rubric of ‘neighborhood wars’ obscures multipolar conflicts around the discontents stemming from authoritarianism and democratization.     

Planning Discourse versus Land Discourse: The 2009–12 Reforms in Land‐Use Planning Policy and Land Policy in Israel

Land policy and land‐use planning policy are two types of public policy pertaining to space. In general, land‐use planning policy deals with land‐use allocation and property rights, whereas land policy defines the land regime of a society. These differences have shaped a unique discourse for each of these policy types. The purpose of this article is to examine the differences and similarities between the land discourse and the planning discourse by analyzing two public campaigns conducted in Israel against two proposed reforms: the 2009 reform of the Israel Land Administration and the 2010–12 reform of the Planning and Building Law. The findings reveal substantive differences between the two campaigns, manifested in the nature of the leading players, the types of public activities they chose, and most notably in the discourses and the hierarchy of considerations they addressed. The findings raise profound questions regarding universal trends in spatial policy reforms; their influence on the activities of public coalitions and the discourses they adopted; possible future effects of these trends on the differences between the land discourse and the planning discourse; and the impact of these trends on the ability of groups and individuals elsewhere to influence spatial policies (such as planning and land policies).     

Entry dynamics of self-employment in South Korea

The purpose of this paper is to clarify whether the entry into self-employment was an inevitable move due to economic recession (push hypothesis) or a voluntary move due to entrepreneurship (pull hypothesis) in Korea. It also examines how this decision is affected by changes in socio-economic conditions. The empirical analysis in this study exploited the matched sample for the adjacent months in the Economically Active Population Survey (EAPS) conducted by Korea National Statistical Office in 2000–2004. The empirical results showed that the push aspect of self-employment was strong in Korea over the whole sampled periods. The entry into self-employment in South Korea is largely attributable to economic sluggishness and an increase in unemployment rather than a voluntary transition resulting from entrepreneurship. Policy environment (such as providing information and financial support for new start-ups after the Asian financial crisis), which is a country-specific factor magnified the pushed effects. For the pushed (unprepared) self-employed people, not only is there a need to expand the coverage of vocational training programmes, but also it is vital that social safety nets are strengthened and supplemented.     

Community entrepreneurship - cases and conceptualization *

As starting and managing a small business means both social and economic risk taking so is building a robust community a social as well as an economic endeavour. Such a community is a most vital context for entrepreneurship. If located in a remote area and if the environment is hostile cooperation is stimulated between firms and other community groups. Their success is especially ascribed to qualified community entrepreneurship, i.e. personal and innovative ways of building support for local autonomous entrepreneurs. An integrative approach to local economic development is illustrated by two successful, albeit contrasting, Swedish cases.

The cases are reviewed with the help of a conceptual framework that particularly points out the importance of local and global networking in both community and autonomous entrepreneurship. In a mixed economy such networks must be carefully managed and encompass linkages on, beside the market, institutional and political arenas. The very role of the community entrepreneur is to bridge these different settings through alert leadership, if required organized as a team.     

Contextual factors affecting the integration of enterprise systems in post-merger oil and gas companies

This study examines the contextual factors of the external business environment, organization, information systems, and enterprise system software as they affect integration of enterprise resource planning (ERP) systems after a merger or acquisition in the oil and gas industry. A multiple case study method using primary and secondary data revealed: ERPs are operational necessities rather than strategic differentiators; best practice adoption is a viable alternative that supports successful integration of cultures and knowledge from two experienced organizations; schedules are extended when best practices from both companies are consolidated into a single instance; consolidation facilitates Sarbanes-Oxley compliance and lowers the cost of ownership; imposing acquirer systems on targets facilitates timely decision-making and shorter schedules.     

Learn not to learn–a way of keeping budgets and deadlines in ERP projects?

This paper takes as its point of departure the conflict between the project as an organisational form for time-limited task execution and the project as an organisational form for triggering knowledge development and learning. The aim of the paper is to explore how knowledge developed in ERP projects can be managed, as well as to identify potential influences on the management of knowledge developed in the project process. Qualitative data has been collected through interviews, document studies, and participant observations. The paper presents evidence that problems of keeping to budgets and timelines in ERP projects can depend on the fact that knowledge developed in the project process is also exploited in the project process. In order to bridge the conflict between the project as a time-limited form for task execution and an organisational form for knowledge development and learning, three tentative strategies for exploiting knowledge developed in the project process are suggested.     

Effects of people-centred factors on enterprise resource planning implementation project success: empirical evidence from Sri Lanka

Extant literature suggests people-centred factors as one of the major areas influencing enterprise resource planning (ERP) implementation project success. Yet, to date, few empirical studies attempted to validate the link between people-centred factors and ERP implementation project success. The purpose of this study is to empirically identify people-centred factors that are critical to ERP implementation projects in Sri Lanka. The study develops and empirically validates a framework for people-centred factors that influence the success of ERP implementation projects. Survey research methodology was used and collected data from 74 ERP implementation projects in Sri Lanka. The people-centred factors of ‘project team competence’, ‘rewards’ and ‘communication and change’ were found to predict significantly the ERP implementation project success.     

Research on e-commerce transaction networks using multi-agent modelling and open application programming interface

We provide a formal definition of an e-commerce transaction network. Agent-based modelling is used to simulate e-commerce transaction networks. For real-world analysis, we studied the open application programming interfaces (APIs) from eBay and Taobao e-commerce websites and captured real transaction data. Pajek is used to visualise the agent relationships in the transaction network. We derived one-mode networks from the transaction network and analysed them using degree and betweenness centrality. Integrating multi-agent modelling, open APIs and social network analysis, we propose a new way to study large-scale e-commerce systems.     

A case study of exploiting enterprise resource planning requirements

The requirements engineering (RE) processes have become a key to conceptualising corporate-wide integrated solutions based on packaged enterprise resource planning (ERP) software. The RE literature has mainly focused on procuring the most suitable ERP package. Little is known about how an organisation exploits the chosen ERP RE model to frame the business application development. This article reports an exploratory case study of a key tenet of ERP RE adoption, namely that aligning business applications to the packaged RE model leads to integral practices and economic development. The case study analysed a series interrelated pilot projects developed for a business division of a large IT manufacturing and service company, using Oracle's appl1ication implementation method (AIM). The study indicated that AIM RE improved team collaboration and project management experience, but needed to make hidden assumptions explicit to support data visibility and integrity. Our study can direct researchers towards rigorous empirical evaluations of ERP RE adoption, collect experiences and lessons learned for practitioners, and help generate more effective and mature processes when exploiting ERP RE methods.
