The paper argues that attitudes to SOA follow a typical hype cycle from Technological Trigger, Peak of Inflated Expectations,
and a Trough of Disillusionment to the more recent realization that SOA is a concept that may offer certain benefits but has
several limitations. The main research question studies how the attitude to SOA changes in various phases of the hype cycle,
how the SOA implementation cycle and an increase in business process maturity (BPMa) are interconnected and which factors
influence the transition between the hype cycle phases. The paper shows that an organization’s success with implementing SOA
depends on its ability to match the SOA implementation with an increase in BPMa. The dual purpose of implementing SOA is shown
in the first framework: to assure the coherence of IT assets and to assure business/IT alignment. In the second framework,
the interconnection of SOA and BPMa and its role in transiting through the hype cycle phases is outlined. The findings are
analyzed using a longitudinal case study of a large Slovenian company. 相似文献

The research project addresses the influence of feedback information on the decision process supported by the application
of system dynamics models. A user-friendly application was developed and used in the experiment with decision groups. The
participants were 174 undergraduate management science students. They had the task of determining the optimum business strategy
by maximizing the multiple criteria function under three experimental conditions: a
1) an indivIDual decision process without the support of a system dynamics model, a
2) an indivIDual decision process supported by a system dynamics model, and a
3) a decision process supported by a system dynamics model and subject interaction via computer mediation. The hypotheses that
the indivIDual decision process supported by a system dynamics model yields higher Criteria Function values than one without
a system dynamics model, as well as the decision process supported by both a system dynamics model and subject interaction
yields higher Criteria Function values than one supported by a system dynamics model alone were confirmed. 相似文献

In this symposium, we explore how urban citizenship is about expressing, if not producing, difference, and how fragmentation of claims affects urban citizenship and right to the city movements with their universal, all‐inclusive ideals. Investigating social movements, political participation and conflicting diversities in public space in Tel Aviv and Berlin, we see a trend towards a diversification of interests, a weakening of movements, and even a competition over rights and resources rather than a development of mutual support and solidarities among various groups on the pathway to a livable city. This tension, we argue, deserves attention. Radical urban scholarship and politics need to better understand the historical and place‐specific contexts that structure the formation of citizenship claims and the courses that citizenship struggles take. Celebrations of urban citizenship as a more contextualized, community oriented, and bottom‐up framework (in comparison to national citizenship) should therefore be complemented by a careful investigation of their fragmented and fragmenting practices. 相似文献

The nonlinear regression model with N observations y
i=η(x
i,θ) +εi, and with the parameter θ subject to q nonlinear constraints C
j (θ)=0; j=1, …,q, is considered. As an example, the spline regression with unknown nodes is taken. Expressions for the variances (variance
matrices) of the LSE are discussed. Because of the complexity of these expressions, and the singularity of the variance matrix
of the LSE for θ, the optimality criteria and their properties, in particular the convexity and the equivalence theorem are
considered from different aspects. Also the possibility of restriction to designs with limited values of measures of nonlinearity
is mentioned.

This study critically evaluates industrial relations (IR) in South-Eastern Europe and points towards future practical and research-oriented opportunities in the region. A survey of organizational policies and practices has been used to explore the state of IR in both private and public organizations in this region. Specifically, the data, collected in 2009–2010 (including the latest changes due to the economic crisis), cover 840 different organizations located in Slovenia, Serbia, Bulgaria, Greece and Cyprus. We discuss the development of ‘regional-specific’ IR policies, the ‘importing’ of varieties of capitalism models, the diffusion of the European Union social model and the role of foreign MNCs in changing IR in the region. 相似文献

ABSTRACTA quantitative turn in history of economic thought is looming. We argue that engineering it consciously is of crucial importance for historians of economics. We also highlight the limitations of quantitative techniques. Yet, the combination of qualitative and quantitative research could substantially enrich our narratives of the development of economics and its practice, of how ideas and tools disseminate and influence other spheres. A failed quantitative turn could lead our field to a house divided and, in the worst case, a civil war. 相似文献
