The purpose of this paper is to show how digital watermarking can be applied to assist and improve cryptography‐based digital rights management (DRM) systems by allowing the protection of content beyond the domain protected by the DRM system.

Digital watermarking is a passive technology, not allowing the active prevention of copyright violations. But it allows the irreversible linking of information with multimedia data, ensuring that an embedded watermark can be retrieved even after analogue copies. Therefore watermarking can be used where DRM fails: whenever content needs to be moved out of the protected DRM domain, e.g. when playing back content via analogue output channels it can mark the content with information that would help to identify its origin if it is used for copyright violations. The remaining challenge now is to find the marked content within the channels regularly used for copyright violations. The paper therefore introduces a concept for scanning file sharing networks for marked content.

The vast number of files present in the file sharing networks prohibits every approach based on completely scanning and analysing each file. Therefore concepts for filtered search queries where only potentially watermarked files are downloaded are discussed.

The paper shows how watermarking can be applied as a technology to allow active content protection beyond the limitations of current DRM systems.

The purpose of this Guest Editorial is to introduce the papers in this special issue.

A brief summary of the main contributions of the papers included in this issue is provided.

In order to combat the digital information war it was found that important work must be done to establish both users' and content providers' trust through fair e‐commerce/digital rights management (DRM).

The paper provides an overview of the basic requirements of DRM systems.

Many current video games feature virtual worlds inhabited by autonomous 3D animated characters. These characters often fall short in their ability to participate in social interactions with each other or with people. Increasing the social capabilities of game characters could increase the potential of games as a platform for social learning. This article presents advances in the area of social autonomous character design. Specifically, a computational model of social relationship formation is described. This model formed the basis for a game entitled “AlphaWolf” that allows people to play the role of newborn pups in a pack of virtual wolves, helping the pups to find their place in the social order of the pack. This article offers the results from a 32‐subject user study that assessed the social relationship model, showing that it effectively represents the core elements of social relationships in a way that is perceivable by people. Additionally, this article proposes a game that will allow parents, teachers and children to experiment with computational social behavior through social virtual characters. This research contributes to the development of games for social learning by offering a set of viable algorithms for computational characters to form social relationships, and describing a project that could utilize this model to enable children to learn social skills by interacting with game characters.

This paper examines the case of Nashoba, a Tennessee-based social enterprise founded in 1824 by Scottish immigrant Frances Wright. The Nashoba venture intended to diminish the institution of slavery in the USA through entrepreneurial activity over its five years of operation.

This study methodology entailed mining primary source data from Wright’s letters; communications with her cofounders and contemporaries; and documentations of enterprise operations. The authors examined these data using social enterprise theory with a focus on personal identity and time-laden empirical aspects not captured by traditional methodologies.

The social enterprise concept of a single, self-sustaining model generating more than one denomination of value in a blended form has a deeper history than the literature acknowledges. As an entrepreneur, Wright made strategic decisions in a context of supply-side and demand-side threats to the venture. The social enterprise engaged injustice by going beyond market and state contexts to generate impact in the realms of institutions and non-excludable public goods.

This study generates two formal implications for the development of new research questions in social enterprise studies. The first implication addresses the relation between social entrepreneurs and their constituencies. The second implication pertains to the effects of macro-level education, awareness and politics on social enterprise performance and impact. The implications herald new insights in social enterprise, such as the limits of moral conviction and the importance of social disruption.

This paper broadens the current understanding of how social enterprises redress unjust and unethical institutions. It also contributes new insights into social enterprise launch and growth based on shared values within communities and coordinated strategic intentions across communities.

This paper aims to examine whether the money laundering/terrorist financing (ML/TF) model excludes important aspects of terrorist resourcing and whether the terrorist resourcing model (TRM) provides a more comprehensive framework for analysis.

Research consisted of case studies of resourcing activities of four listed terrorist organizations between 2001 and 2015: the Liberation Tigers of Tamil Eelam (LTTE), Hamas, a grouping of Al Qaeda-inspired individuals and entities under the heading “Al Qaeda inspired” and Hezbollah.

The most prevalent resourcing actors observed were non-profit organizations/associations, and the most prevalent form of resourcing was fundraising that targeted individual cash donations of small amounts. Funds were pooled, often passed through layers of charitable organizations and transmitted through chartered banks. The TRM is indeed found to provide a more comprehensive framework for identifying sources of resourcing and points of intervention. However, it does not in itself recommend effective means of response but it has implications for counter-resourcing strategies because it identifies resourcing actors and nodes where counter-resourcing could occur.

This paper advances the state of knowledge of terrorist resourcing activities in Canada and about the value of doing so through the analytical lens of the TRM as opposed to the predominant ML/TF model.

Blues music is in the midst of its second revival in popularity in roughly thirty years. The year 1960 can be identified, with some qualification, as a reference point for the first rise in international awareness and appreciation of the blues. This first period of wide‐spread white interest in the blues continued until the early seventies, while the current revival began in the middle 1980s. During both periods a sizeable literature on the blues has appeared. This article provides a thumbnail sketch of the popularity of the blues, followed by a description of scholarly and critical literature devoted to the music. Documentary and instructional materials in audio and video formats are also discussed. Recommendations are made for library collections and a list of selected sources is included at the end of the article.

This paper seeks to explore leading theories and concepts in professionalising the emerging field of business district management.

In the context of globalization and localization, it discusses distinctive place‐based elements of business improvement districts (BIDs), such as: law, nomenclature, assessment formulae, and branding; while suggesting and analyzing strategic international application of certain theories and concepts.

As an outgrowth of a literature review of globalizing cities, public administration, urban management, and BIDs together with semi‐structured interviews of respondents in connection with doctoral dissertation research and in view of co‐designing curriculum for and teaching a business district management certification program; research reveals that public entrepreneurship, social capital, network governance, and performance management can transcend disciplines and cut across sectors to be key theories and concepts for education and training of business district managers worldwide. However, management training is to be contextually developed consistent with branding techniques for the business district.

Future research and evaluation of BIDs in the globalizing metropolis can ground theory to inform best practices and professional standards that will enable similarly situated business districts across the globe.

Examining BID management is not new, however the thrust toward professionalising the field is new.

This systematic literature review analyses the determinants and consequences of executive compensation-related shareholder activism and say-on-pay (SOP) votes. The review covers 71 empirical articles published between January 1995 and September 2017. The studies are reviewed within an empirical research framework that separates the reasons for shareholder activism and SOP voting dissent as input factor on the one hand and the consequences of shareholder pressure as output factor on the other. This procedure identifies the five most important groups of factors in the literature: the level and structure of executive compensation, firm characteristics, corporate governance mechanisms, shareholder structure and stakeholders. Of these, executive compensation and firm characteristics are the most frequently examined. Further examination reveals that the key assumptions of neoclassical principal agent theory for both managers and shareholders are not always consistent with recent empirical evidence. First, behavioral aspects (such as the perception of fairness) influence compensation activism and SOP votes. Second, non-financial interests significantly moderate shareholder activism. Insofar, we recommend integrating behavioral and non-financial aspects into the existing research. The implications are analyzed, and new directions for further research are discussed by proposing 19 different research questions.
