Effective Collaboration

This chapter features a case study of a collaborative project among a team of writers and a team of multimedia designers and examines their intersections. The chapter’s central question is: What does it take to enable collective collaboration in a virtual writing environment? The chapter is based in part on a study that found that building and strengthening social presence is integral to effective collaboration. The spoken and unspoken social contracts of working toward a common goal in a respectful environment are important. It also found that the technologies must be adoptable, adaptable, and they must enable anywhere/anytime collaboration. Therefore, collaboration using technologies is a complex process involving social presence, availability, and adaption/adoption of technologies with the changing needs of the collaborative team.

And Control

Overtopping-type wave power conversion devices represent one of the most promising technology to combine reliability and competitively priced electricity supplies from waves. While satisfactory hydraulic and structural performance have been achieved, the selection of the hydraulic turbines and their regulation is a complex process due to the very low head and a variable flow rate in the overtopping breakwater set-ups. Based on the experience acquired on the first Overtopping BReakwater for Energy Conversion (OBREC) prototype, operating since 2016, an activity has been carried out to select the most appropriate turbine dimension and control strategy for such applications. An example of this multivariable approach is provided and illustrated through a case study in the San Antonio Port, along the central coast of Chile. In this site the deployment of a breakwater equipped with OBREC modules is specifically investigated. Axial-flow turbines of different runner diameter are compared, proposing the optimal ramp height and turbine control strategy for maximizing system energy production. The energy production ranges from 20.5 MWh/y for the smallest runner diameter to a maximum of 34.8 MWh/y for the largest runner diameter.

The Impact

The Case Study section of the International Journal of Entrepreneurship and Innovation serves two purposes. First, the case studies presented are concerned with problematical issues that are pertinent to students of entrepreneurship. Thus they constitute appropriate teaching and learning vehicles on a variety of postgraduate and undergraduate programmes. Each case study is accompanied by a set of guidelines for the use of tutors. Second, it is envisaged that those engaged in entrepreneurial activities will find the cases both interesting and useful. The case of PSA Peugeot Citroën's electric passenger car is an example of an innovation perceived as a failure because of its disappointing sales volume. Yet, by limiting our assessment of the electric passenger car to a short-term perspective, we may miss out on an essential part of its value. As part of a wider innovation process, the electric passenger car project is a significant step for PSA in its expertise regarding electric vehicles. Key learning outcomes: (a) to understand that innovation is a complex process with fuzzy frontiers, both in time and space; (b) to understand that innovation is a long-term investment with spillovers into other projects; (c) to be aware of the multiple perspectives that may be adopted when examining innovation; and (d) to be aware of the impact of labelling a project a failure.

Gathering Data

A top-down approach to the mineralized structures and developmental steps that can be separated in the shells of Pinctada margaritifera was carried out. Detailed characterizations show that each of the two major layers usually taken into account (the outer prismatic layer and the inner nacreous layer) is actually the result of a complex process during which the microstructural patterns were progressively established. From its early growing stages in the deeper part of the periostracal grove up to the formation of the most inner nacreous layers, this species provides a demonstrative case study illustrating the leading role of specifically secreted organic structures as determinants of the crystallographic properties of the shell-building units. Gathering data established at various observational scales ranging from morphology to the nanometer level, this study allows for a reexamination of the recent and current biomineralization models.

Names Project

The NAMES Project AIDS Memorial Quilt is a collaborative project that memorializes individuals who have died of AIDS-related causes. Since its inception, it has become the world’s largest public folk art project. Scholars have noted the Quilt’s materiality, scope, and cultural importance to collective memory processes related to HIV/AIDS. More recently, discussions of collective memory in the digital public sphere have attracted attention from new media theorists and memory scholars alike. @theAIDSmemorial (TAM) is an Instagram account that serves as a digital repository for a new form of connective memory. By assessing two AIDS memorials as comparative cases, this research argues that TAM’s digital affordances of interactivity and reach are evident, although in assessing the digital remediation of the NAMES Project AIDS Memorial Quilt, the materiality, metaphoric origins, and scope of the Quilt cannot be rendered on digital platforms, representing a loss in affective engagement.

This article proposes a study of the violation of contract process through a case study. The study is based on a discourse of the union, SUD Michelin, which is contrasted both with those of another union, the CFE-CGC Michelin and of the senior management of the corporation. The results highlight the possibility of applying Morrison and Robinson’s (1997) Psychological Contract Violation model at the social contract level. The emotional reactions appearing in the literature, which are associated with contract violations, can be seen in the union discourse of the SUD. The other union does not perceive any breach of contract. These differences may be attributed to the very nature of social contracts—relational in the first case, and more balanced in the second.

Complex Process

Shipbuilding is a very important industry for its irreplaceable role into the sea transport and oceans exploration. But ship production design is a very complex process, causing the inefficiency of the shipbuilding. At the same time, the current situation of most shipbuilding enterprises is the multi-project environment and the resources among them are shared, the large and complex systems are hardly to simulate. In this research, a multi-resources oriented hierarchical timed petri net (HTPN) are constructed to model the ship production design process under the multi-project environment and a WFPN software is developed based on HTPN. To evaluate the efficiency and applicability of WFPN, a case study is conducted and the results show that it’s practicable. Beside on it, the analyses of the resource loads are also providing a way to promote the efficiency of the shipbuilding enterprises.
