  • Synthesis of an oxetane‐functionalized hemispiroorthocarbonate used as a low‐shrinkage additive in the cationic ultraviolet curing of oxetane monomers
    Journal of Applied Polymer Science, 2009
    Co-Authors: Marco Sangermano, S. Giannelli, R. Acosta Ortiz, M. L. Berlanga Duarte, A. K. Rueda Gonzalez, Aida E. Garcia Valdez
    Abstract:

    The synthesis of an hemispiroorthocarbonate functionalized with an oxetane group is reported. The obtained monomer was used as a slow shrinkable additive in the cationic ultraviolet curing of a commercially available dioxetane resin. We evidenced polymer network Flexibilization by increasing the oxetane-functionalized hemispiroorthocarbonate content in the photocurable formulation. It was demonstrated that spiroorthocarbonate acted as a shrinkage reduction additive and reached expansion on volume after polymerization in the presence of 50 wt % of the functionalized spiroorthocarbonate. © 2009 Wiley Periodicals, Inc.

  • Synthesis of an epoxy functionalized spiroorthocarbonate used as low shrinkage additive in cationic UV curing of an epoxy resin
    European Polymer Journal, 2008
    Co-Authors: Marco Sangermano, Ricardo Acosta Ortiz, Bertha A. Puente Urbina, Lydia Berlanga Duarte, Aida E. Garcia Valdez, Ramiro Guerrero Santos
    Abstract:

    The synthesis of an epoxy functionalized spiroorthocarbonate (SOC) is reported. The obtained monomer has been used a slow shrinkable additive in cationic UV curing of a commercially available dicycloepoxy resin. A polymer network Flexibilization was evidenced by increasing the SOC content in the photocurable formulation. It has been demonstrated that SOC acts as shrinkage reduction additive reaching expansion on volume after polymerization in the presence of 10 wt% of the functionalized spiroorthocarbonate.

  • Photopolymerization of oxetane based systems
    European Polymer Journal, 2004
    Co-Authors: Marco Sangermano, Giulio Malucelli, Roberta Maria Bongiovanni, Aldo Priola
    Abstract:

    Oxetane based systems were investigated in cationic photopolymerization process. The effect on the rate of polymerization induced by the presence of epoxy monofunctional monomers and vinyl ether monomers were investigated. In both cases an increase of the rate of polymerization is evidenced either induced by a Flexibilization effect due to a copolymerization or to a cross-propagation mechanism. Acrylate comonomers were also investigated and the formation of an IPN tightly cross-linked evidenced.

  • Flexibilization of the methodology of system development
    Information and Software Technology, 1995
    Co-Authors: Gertjan Vlasblom, Daan B. B. Rijsenbrij, Matthijs Glastra
    Abstract:

    Abstract Many of the existing methods for the development of information systems have traditionally been seen as models with rigid phasing. This has mainly come about by the use that has been made of them; the freedom to suit methods to the circumstances has been present in some methods, but this has attracted little attention. This paper shows how the necessary flexibility can be brought to the foreground. An analysis of the elements of development methods leads then to a methodology in three layers: the generic level, the model level and the (project) specific level. A crucial role is played here by the concept of ‘development model’; after having investigated how development models are used and which role the situation profile plays, we describe how these development models can be drawn up. Several real examples, from the authors' business practice, conclude the paper.

  • Embedded Flexibilization and polite employer domination: the case of short-track apprenticeships in Switzerland
    Empirical Research in Vocational Education and Training, 2020
    Co-Authors: Gina Di Maio, Lukas Graf, Anna Wilson
    Abstract:

    Liberalization pressures challenge countries to adapt their training systems. This is particularly relevant for coordinated market economies with firm-driven but collectively governed apprenticeship systems. Recent literature has identified different liberalization trajectories for these countries. For instance, segmentalism describes the increasing influence of large employers in Germany. In Denmark, state agencies manage increased flexibility in training through embedded Flexibilization. In this paper, we identify a new form of embedded Flexibilization, characterized by polite employer domination. We find this trajectory of liberalization in Switzerland, which represents another training system heavily based on firm involvement. We illustrate our argument with the example of short-track apprenticeship training, which has been expanded in all three mentioned countries in response to ongoing liberalization and deindustrialization pressures.

We illustrate our argument with the example of short-track apprenticeship training, which has been expanded in all three mentioned countries in response to ongoing liberalization and deindustrialization pressures. In Switzerland, the relevant reform was initiated by the state while business adopted a rather passive role initially. Yet, state actors eventually stepped back and delegated key competences to employers, which implies that the employers’ camp asserted their interests in the end while tolerating some concessions for the benefit of disadvantaged groups. Our process tracing reveals that policy makers used layering to implement short-tracks that enhance social inclusion, while simultaneously increasing the scope of employer cooperation.

  • Trajectories of Liberalization in Collective Governance: The Swiss Case of Polite Employer Domination and Embedded Flexibilization
    2019
    Co-Authors: Gina Di Maio, Lukas Graf, Anna Wilson
    Abstract:

    Increasing liberalization challenges countries to adapt their training systems. Collective skill formation systems, systems with dual vocational apprenticeship training, have developed different trajectories of change. Germany’s training system is ever more influenced by large employers (segmentalism) while in Denmark the state agencies are managing increased flexibility in training through embedded Flexibilization. In this context, one key example discussed in the literature is the introduction of short-track dual training programs. Switzerland, another typical collective skill formation country, also introduced short-tracks in the early 2000s but has not yet been analysed through the lens of liberalization trajectories. Our institutional analysis finds that Swiss short-tracks represent a case of embedded Flexibilization – usually associated with Scandinavian countries. However, in contrast to Denmark, the Swiss variation is much more employer-friendly. Our process tracing reveals that policy makers in Switzerland used layering in order to implement short-tracks that enhance social inclusion while maintaining a high level of employer engagement.

  • ECIS - Flexibilization of Service Processes : Toward an Economic Optimization Model
    2013
    Co-Authors: Lydia Caroline Natalie Neuhuber, Felix Krause, Maximillian Roeglinger
    Abstract:

    Although the importance of flexibility has long been recognized in the service industry, scholars and practitioners alike still struggle to express the value of flexible services in economic terms. We perceive that many service providers tend to strive for very flexible service processes no matter in which ecosystem they are embedded. They invest huge amounts of money in Flexibilization projects without being able to justify their decisions in line with economic criteria. Scholars, in contrast, advise against investing as much as possible in Flexibilization. Concrete recommendations, however, are missing. Especially insights into the positive economic effects of flexible service processes require more attention. Against this backdrop, we propose an economic optimization model as a first step to capture the general relationships that govern the Flexibilization of service processes. The optimization model enables service providers to estimate appropriate levels of volume and functional flexibility and to select Flexibilization projects accordingly. We also provide first insights into the applicability of the optimization model via a demonstration example.
