This paper aims to examine the concept of participatory governance through membership in the context of the tailor-made legal form for social enterprises in Greece, i.e. the social cooperative enterprise (Koinsep). As such, the paper aims to contribute to the theoretical discussion regarding the participation of stakeholders in the governance of social enterprises not only as a theoretical construct prescribed by law but also by examining its implementation in practice.

The development of two in-depth case studies demonstrate whether and how the application and implementation of legal requirements regarding governance and membership permit and encourage stakeholders to participate in the decision-making processes of social enterprises. The study accordingly showcases the influence exerted by the legal regime over the social enterprise.

The case studies demonstrate how participatory governance is not realised in a formal manner in the organisational set-up of two social enterprises. It thereby shows how stakeholders and employees participate informally in the decision-making processes of Greek social enterprises, although legislation is conducive to formal means of participation.

This study is part of a larger project involving a comparative research of tailor-made legal forms of social enterprises and corresponding organisations in three jurisdictions, i.e. Greece, Belgium, and the UK. In this study, the research was limited to the legal form of Koinsep.

This paper also contributes to the development of a better understanding of the Koinsep as a new tailor-made legal form for social enterprises in Greece. It therefore, sheds light in its function and its participatory governance structure.

The study is an original attempt to theoretically and practically examine the subject of participatory governance in the Greek social enterprises context.

I argue that while group and organizational identity research is gaining in popularity, there has not been sufficient attention paid to explicating what identity refers to at the level of the collective. The goal of this chapter is to ‘disentangle’ various issues associated with the concept of collective identity. To meet this goal, I pose questions that scholars should consider when engaging in identity-related research. I begin by asking, “Is it identity?” Here, I address the characteristics that are central to identity, and that differentiate it from similar constructs (e.g. culture). I then ask, “Is it collective identity?” Here, I address issues of levels of analysis, identity locus and origin, as well as how identity comes to be shared in the collective via socialization and media. I conclude by discussing how identity research can be enhanced by more carefully considering these fundamental questions, and suggest some terms that scholars can employ to make their identity-related assumptions and arguments clearer and more precise.

The purpose of this paper is to outline a theoretical approach to approximate reasoning. The author shares the view that the emergence of an algebraic approach is vital for the advancement of conceptual understanding as well as technical knowledge of knowledge engineering. The notion of a knowledge diagram is suggested as a unifying framework to explain some significant results in this area. This is a categorial point of view promoting the idea that the concept of transformation be taken as fundamental in place of membership. Entities are characterized by their universal properties which specify their role in relation to other entities. Once the operational description is known, internal structure is of lesser importance.

The purpose of this paper is to portray social learning in cluster initiatives (CIs), namely, to explore, with the lens of the communities of practice (CoPs) theory, in what ways social learning occurs in CIs and discover how various CoPs emerge and evolve in CIs to facilitate a collective journey in their learning process. Subsequently, the authors address the following research questions: In what ways does social learning occur in CIs? How is social learning facilitated through the emergence and evolution of various CoPs in CIs?

The study applies the abduction approach for the interpretation of the collected data and attempts to create the best explanations for the observations on the basis of the CoP theory. The qualitative study of four CIs helped to identify various ways that social learning occurs in CIs and the role of the identified CoPs in the process. Social learning is portrayed as a collective journey within and between CoPs, where the interactions of their members deepen their level of involvement and help them to enhance learning in their CoP.

The paper shows ways that social learning occurs in CIs and describes the role of CoPs. It identifies three types of CoPs in CIs: participants, cooperators and locomotives. Additionally, it documents different ways of social learning in CIs, namely, one-way or two-way information transfer and raising awareness; demonstrating and inspiring; or motivating and educating. It also shows that while potentially every member of a CI has access to these practices, only a limited number of members are actually involved. Social learning in CIs is selective and some CI members accept their role as more peripheral in their CI.

The research shows the application of the CoP theory to the analysis of social learning in CIs, a peculiar type of clusters. It describes how CoPs in the studied CIs varied in terms of the occurrence of learning. Furthermore, it reveals how social learning related to the level of involvement of CI members, namely, with an increase of involvement, the members formed more selective CoPs and strengthened their social learning. Nevertheless, the qualitative approach in the study and the specific sample of the CIs chosen for the analysis do not allow a generalization of the findings.

Although in different CoPs social learning occurs in different ways, at each stage of the development of CIs, the learning process is carried out on the basis of interactions created among members. Therefore, it is important to support the “soft” forms of cooperation within CIs – involving members in activities and developing interactions. In addition, to ensure the growth of their entire CI, coordinators should create conditions for the development of existing CoPs into higher forms, which better support learning. They should also adopt boundary-spanning roles between various CoPs to strengthen social learning in CIs.

The literature on CIs, which are peculiar forms of clusters, is still underdeveloped. The research fills in the gap concerning the ways social learning occurs in CIs. It shows that selectiveness can be observed in this process, and emphasizes the role of interactions developed through CoPs and the benefits offered by them. The study applies the CoP approach. Consequently, it expands the theoretical base in view of the generally lacking studies on social learning in CIs in the literature on clustering. Because the CoP theory has rarely been applied in the management literature, it also augments this specific field.

The professionalization of project management (PM) profession has developed differently according to the different environments in which it has been introduced. The purpose of this paper is to examine an example of this professional project (Italy) with this research question: “what have been the professionalization strategies of PM professional associations within Italian field?”

The authors develop a qualitative case study made up of semi-structured interviews and archival data.

The analysis demonstrates how PM in Italy has embarked on a clear upward trajectory in terms of its occupational size, economic significance and institutional development. However, the development of PM in Italy considerably lags behind Anglo-Saxon countries. The authors also identify three main strategies through which this professionalization project is being accomplished (see Section 5). These are corporate engagement, expanding membership and institutional recognition.

The study reviews the professionalization of PM in Italy. This is not a comparative study, but rather highlights Italian PM professionalization. Moreover, the authors expect significant findings could be reached with a comparable research across different national contexts.

This work constitutes the first detailed and comprehensive study in the field of PM within the Italian context.

In the Web 2.0 era, users massively communicate through social networking services (SNS), often under false expectations that their communications and personal data are private. This paper aims to analyze privacy requirements of personal communications over a public medium.

This paper systematically analyzes SNS services as communication models and considers privacy as an attribute of users’ communication. A privacy threat analysis for each communication model is performed, based on misuse scenarios, to elicit privacy requirements per communication type.

This paper identifies all communication attributes and privacy threats and provides a comprehensive list of privacy requirements concerning all stakeholders: platform providers, users and third parties.

Elicitation of privacy requirements focuses on the protection of both the communication’s message and metadata and takes into account the public–private character of the medium (SNS platform). The paper proposes a model of SNS functionality as communication patterns, along with a method to analyze privacy threats. Moreover, a comprehensive set of privacy requirements for SNS designers, third parties and users involved in SNS is identified, including voluntary sharing of personal data, the role of the SNS platforms and the various types of communications instantiating in SNS.

Recent research finds that producers assigned to multiple categories receive less attention and legitimacy and have lower chances of success and survival. We argue that the effect of category spanning on the reception from the audience depends on the fuzziness of the categories. When a set of categories lacks contrast (have very fuzzy boundaries), spanning them does not cause much additional confusion for the audience, thus the penalties associated with spanning ought to be slight. But, when the contrasts of the categories spanned are high, audience members will have difficulty interpreting the producer, so spanning categories will be devalued more. We study these processes using data from an online-review web site. Results show that audience members devalue organizations that span high-contrast categories more than those that span low-contrast categories. These effects are weaker for more active reviewers.

Concurrency is a desirable property that enhances workflow efficiency. The purpose of this paper is to propose six polynomial-time algorithms that collectively maximize control flow concurrency for Business Process Model and Notation (BPMN) workflow models. The proposed algorithms perform model-level transformations on a BPMN model during the design phase of the model, thereby improving the workflow model’s execution efficiency.

The approach is similar to source code optimization, which solely works with syntactic means. The first step makes implicit synchronizations of interdependent concurrent control flows explicit by adding parallel gateways. After that, every control flow can proceed asynchronously. The next step then generates an equivalent sequence of execution hierarchies for every control flow such that they collectively provide maximum concurrency for the control flow. As a whole, the proposed algorithms add a valuable feature to a BPMN modeling tool to maximize control flow concurrency.

In addition, this paper introduces the concept of control flow independence, which is a user-determined semantic property of BPMN models that cannot be obtained by any syntactic means. But, if control flow independence holds in a BPMN model, the model’s determinism is guaranteed. As a result, the proposed algorithms output a model that can be proved to be equivalent to the original model.

This paper adds value to BPMN modeling tools by providing polynomial-time algorithms that collectively maximize control flow concurrency in a BPMN model during the design phase of the model. As a result, the model’s execution efficiency will increase. Similar to source code optimization, these algorithms perform model-level transformations on a BPMN model through syntactic means; and the transformations performed to each control flow are guaranteed to be equivalent to the control flow. Furthermore, a case study on a real-life new employee preparation process is provided to demonstrate the proposed algorithms’ usefulness on increasing the process’s execution efficiency.
