This special issue presents papers based on contributions to the first international workshop on the “Theory and Practice of Differential Privacy” (TPDP) held in London, UK, 18 April 2015, as part of the European joint conference on Theory And Practice of Software (ETAPS). Differential privacy is a mathematically rigorous definition of the privacy protection provided by a data release mechanism: it offers a strong guaranteed bound on what can be learned about a user as a result of participating in a differentially private data analysis. Researchers in differential privacy come from several areas of computer science, including algorithms, programming languages, security, databases and machine learning, as well as from several areas of statistics and data analysis. The workshop was intended to be an occasion for researchers from these different research areas to discuss the recent developments in the theory and practice of differential privacy. The program of the workshop included 10 contributed talks, 1 invited speaker and 1 joint invited speaker with the workshop “Hot Issues in Security Principles and Trust” (HotSpot 2016). Participants at the workshop were invited to submit papers to this special issue. Six papers were accepted, most of which directly reflect talks presented at the workshop

Differential privacy is a promising approach to privacy-preserving data analysis that provides strong worst-case guarantees about the harm that a user could suffer from contributing their data, but is also flexible enough to allow for a wide variety of data analyses to be performed with a high degree of utility. Researchers in differential privacy span many distinct research communities, including algorithms, computer security, cryptography, databases, data mining, machine learning, statistics, programming languages, social sciences, and law. Two articles in this issue describe applications of differentially private, or nearly differentially private, algorithms to data from the U.S. Census Bureau. A  third article highlights a thorny issue that applies to all implementations of differential privacy: how to choose the key privacy parameter ε, This special issue also includes selected contributions from the 3rd Workshop on Theory and Practice of Differential Privacy, which was held in Dallas, TX on October 30, 2017 as part of the ACM Conference on Computer Security (CCS).

This is the first special issue that JPHE hosts—and could there be a more suitable forum for an issue dedicated to exploring and encouraging a critical dialogue around transformative intercultural communication teaching practices in higher education (HE)? What has led us to engage with the theme of making intercultural education meaningful is a shared observation that there seems to be an increasing disconnect between recent developments in intercultural communication theory and practice. With so much critique published over the years, we are perplexed as to why traditional notions of culture still prevail not only in mainstream intercultural communication research but also in institutional discourses in HE and in popular discourses as articulated by the people who sit—or have once sat—in our classrooms. In this editorial and Special Issue, we approach intercultural communication from a critical angle, akin to the theorization of interculturality as a discursive and contingent, unstable and contradictory, political and ideological construct. We are thrilled to see this approach gain ground in the field of intercultural communication. However, at the same time, we are worried that the terrain of intercultural communication teaching across HE settings has become quite unruly and is characterized by pedagogical solutions that do not have a stable connection to state-of-the-art theory, and that might lead to naive, simplistic, and essentialist understandings of ‘culture’ and ‘the other’.......

Purpose – The purpose of this paper is to introduce the papers in the special issue. Design/methodology/approach – A general description of each paper in the special issue is provided. The introduction highlights the need for more research into the broad topic of the global elite. Findings – Research in the social sciences uses a very broad definition of the global elite. It would be helpful in critical management and organization studies and critical international business research, to begin to identify important and key research areas that enable a more critical investigation of whom the global elite are and how they might be studied. Originality/value – This paper introduces five diverse papers that deal with issues pertaining to a global elite and transnational capitalist class.

Over the last two decades, the awareness about landscape as a common good and the definition of tourism as a relevant driver of territorial development have both increased contributions to contemporary reflections on places and mobilities. From a scientific point of view, the need for structured contributions on the “landscape–tourism” nexus has been stressed. In fact, tourism and landscape studies are fed by many disciplines, often returning sectorial articles, sometimes lacking in organicity. Considering recent literary reviews carried out through bibliometric and content analyses, the present paper intends to map different ways of defining and understanding this complex interrelation as it emerges from the main research areas. From geographical contributions to managerial perspectives addressing destination planning and development, and from sociological non-representational to actor network theories applied to tourism, among others, the nexus is faced by approaches and concepts that are both specific and recurrent. Expressions such as “tourist landscape”, “tourism landscape”, “touristscape” with their different meanings orient this literary investigation informing a tentative conceptual framework where interrelated spatial, social, and symbolic dimensions emerge with a key definitional role. The general aim was to possibly enrich the reflection on this relationship, providing new definitional contributions and conceptual frameworks able to coherently influence both theory and practice.

Abstract Differential privacy has made a significant progress in numerical data preserving. Compared with numerical data, non-numerical data (e.g. entity object) are also widely applied in intelligent processing tasks. But non-numerical data may reveal more user’s privacy. Recently, researchers attempt to take advantage of the exponential mechanism of differential privacy to solve this challenge. Nonetheless, exponential mechanism has a drawback in correlated data protection, which can not achieve expected privacy degree. To remedy this issue, in this paper, an effective correlated non-numerical data release mechanism is proposed by defining the notion of Correlation-Indistinguishability and designing a correlated exponential mechanism to realize Correlation-Indistinguishability in practice. Inspired by the concept of indistinguishability, Correlation-Indistinguishability can guarantee the correlations of the probability distributions between the output distribution and original data the same to an adversary. In addition, we would rather let two Gaussian white samples pass through a designed filter, to realize the definition of Correlation-Indistinguishability, than using independent exponential variables. Experimental evaluation demonstrates that our mechanism outperforms current schemes in terms of security and utility for frequent items mining.

This Special Issue had its genesis in an international Workshop on Agents in Design held in June 2002, at MIT by the Guest Editors. Computational agents have been developed within the artificial intelligence community over an extended period. The concept of an agent can be traced to Carl Hewitt's 1977 work on “actors.” Hewitt defined actors as self-contained, interactive, and concurrently executing objects. Since then, considerable research has gone into developing the concept of an agent and into formalizing agents, developing multiagent systems, and exploring their use. The use of agents in design is more recent, and the first PhDs in the area appeared in the early 1990s. Although a precise and unique definition of an agent has yet to be agreed upon, one distinguishing characteristic of an agent is that it exhibits autonomous behavior. Research on agents in design focuses on two primary areas: how to make agents useful in design, and how to apply them to design tasks. This Special Issue has papers from both areas.

The Discrete-Event System Specification (DEVS) formalism is a modeling formalism based on systems theory that provides a general methodology for hierarchical construction of reusable models in a modular way. When concrete DEVS models are developed using programming languages, it is difficult to ensure they conform to their formal model. Hence, building an implementation of formal models in a way that ensures DEVS formalism correctness is not easy. In this paper, we improve the interplay of abstraction (i.e., formal specification) and concreteness (i.e., programming code implementation) in advancing the theory and practice of DEVS using a specific-designed metamodel. The main contribution is a novel conceptualization of classic DEVS with ports founded on existing approaches but that also includes new improved elements related to the definition of atomic models. That is, our metamodel includes all the concepts and relationships needed to define the formal specification of DEVS atomic models. This allows us to define instances of our conceptualization that comply with the DEVS formal specification. To instantiate our metamodel, we propose a computer-aided environment that has been developed using the Eclipse Modeling Project. As an example, we show how our metamodel can be used to define the classic “switch” model. As a conclusion, we discuss how the final metamodel can be used to support interoperability with DEVS simulation tools.
