Abstract
We propose a generic algorithm for numerically accurate likelihood evaluation of a broad class of spatial models characterized by a high-dimensional latent Gaussian process and non-Gaussian response variables. The class of models under consideration includes specifications for discrete choices, event counts and limited-dependent variables (truncation, censoring, and sample selection) among others. Our algorithm relies upon a novel implementation of efficient importance sampling (EIS) specifically designed to exploit typical sparsity of high-dimensional spatial precision (or covariance) matrices. It is numerically very accurate and computationally feasible even for very high-dimensional latent processes. Thus, maximum likelihood (ML) estimation of high-dimensional non-Gaussian spatial models, hitherto considered to be computationally prohibitive, becomes feasible. We illustrate our approach with ML estimation of a spatial probit for US presidential voting decisions and spatial count data models (Poisson and Negbin) for firm location choices.

Abstract
Purpose
The purpose of this paper is to encourage scholars to look at commonly considered phenomena in international business and cross-cultural research in new ways and to theorize and explore how cultural diversity, distance, and foreignness create value for global organizations. These considerations should result in a more balanced treatment of culture in cross-cultural management (CCM) research.
Design/methodology/approach
The idea that there are negative consequences associated with cultural differences is pervasive in hypotheses formulation and empirical testing in international business and CCM literature, as reflected in widely used constructs such as “cultural distance,” “cultural misfit,” “foreignness,” and related concepts. Consistent with a Positive Organizational Scholarship (POS) perspective on culture and cultural differences, the authors emphasize the positive role of distance and diversity across national, cultural, institutional, and organizational dimensions. In addition, they provide an overview of the contributions to the special issue.
Findings
Examining the positive side of culture is not only beneficial theoretically in terms of filling the existing gaps in the literature, but is also crucial for the practice of international and global business. Accordingly, the contributions to the special issue highlight how explicitly considering positive phenomena can help better understand when and how cultural diversity, distance, and foreignness can enhance organizational effectiveness and performance at multiple levels. They include five research papers, a Distinguished Scholar Essay by Kim Cameron, the Founder of the POS movement, and an interview piece with Richard Nisbett, a Pioneer Researcher in culture and cognition.
Originality/value
The overemphasis on adverse outcomes associated with cultural differences in existing research has hindered the understanding of the processes and conditions that help organizations leverage the benefits of cultural differences in a wide range of contexts. This introductory paper together with the contributions included in the special issue showcases the positive dynamics and outcomes associated with cultural differences, distance, and diversity in a wide range of international business contexts.

Abstract
Presents a case study of a financial services company socializing in student loans. Positions the study in terms of ′sustainable competitive advantage′, ′strategic necessity′ and ′edge toward the market′ hypotheses. Concludes that information systems played ′an essential but essentially derivative role′ in the success of the enterprise.

Abstract
Purpose
To develop a conception of experience and action.
Design/methodology/approach
Phenomenological concepts of subjectivity and meaning are combined with cybernetic concepts of constraint.
Findings
A unified theory of action and experience is developed.
Originality/value
The theory provides a scientific, cybernetic, unifying theory of experience and action applicable to individuals, groups and aggregates.

Abstract
Purpose
The purpose of this paper is to target the problem of awareness of the history of cybernetics as a field with different actors inside and outside cybernetics. It provides a short overview on research and literature during the last two decades and pleads for a multiplicity of historical views.
Design/methodology/approach
Historical research, review of literature.
Findings
While it can be found that there was a growing historical interest in cybernetics, this cannot be claimed for the history of the American Society of Cybernetics (ASC) as an organization and a productive network. One reason seems to be the lack of archival sources. The article provides a proposal to reconstruct such an archive for the history of the ASC.
Originality/value
Stimulation of historical awareness for and in cybernetics.
