Remote sensing of night lights differs from other sources of remote sensing in its ability to directly observe human activity from space as well as in informing us on a new type of anthropogenic threat, that of light pollution. This special issue focuses on studies which used newer sensors than the Defense Meteorological Satellite Program - Operational Line-Scan System (DMSP/OLS). Most of the analyses focused on data from the Visible Infrared Imaging Radiometer Suite (VIIRS) nighttime sensor (also called the Day/Night Band, or VIIRS/DNB in short), for which the first instrument in the series was launched in 2011. In this editorial, we provide an overview of the 12 papers published in this special issue, and offer suggestions for future research directions in this field, both with respect to the remote sensing platforms and algorithms, and with respect to the development of new applications.

The remote sensing of urban ecology and sustainability is an emerging topic to understand the human living environment in urban areas from outer space, airplanes, and unmanned aerial vehicles. In this editorial, we provide an overview of the five papers published in this Special Issue and offer suggestions for future research directions in this field, both with respect to the remote sensing platforms and algorithms and the development of new applications.

The articles in this special issue represent both our attempt as editors to survey the field and provide some clarity for practitioners and teacher educators on fundamental ideas that frame CRP, not to limit its implementation or future research directions, but to ensure that as a community of educators and scholars, we share a common understanding of exactly what it means to be culturally relevant. The articles in this special issue provide both that clarity of the field, and vision for the future.

A rapidly changing business environment generates a growing demand for enterprises to understand their markets. Knowledge about markets is a strategic resource and enterprises are advised to invest in understanding their markets, competitors, and customers. Market orientation is widely studied as a concept describing how enterprises generate and respond to market knowledge. Market orientation is a cultural factor which we analyze in the framework of organizational culture. We examine market orientation as a cultural factor, as adopting a new type of culture inside and outside an organization can be particularly challenging for Small- and Medium-Enterprises (SMEs). SMEs have not been considered as very active participants in global business, where market knowledge is of utmost importance. For example, Keskin (2006) finds that market orientation is an antecedent of learning orientation in SMEs and market intelligence guides their learning processes. This chapter examines both theoretically and empirically how market orientation as a cultural factor is related to the internationalization processes of SMEs. This hopefully helps us to understand how SMEs can develop their businesses to a global level. We will present a qualitative study of four Finnish SMEs representing different phases of internationalization. Finally, discussion on the results and future research directions will be presented.

This Special Issue aims to reflect on knowledge co-production and transdisciplinarity, exploring the mutual interaction between water governance and water research. We do so with contributions that bring examples from diverse parts of the world: Bolivia, Canada, Germany, Ghana, Namibia, the Netherlands, Palestine, and South Africa. Key insights brought by these contributions include the importance of engaging the actors from early stages of transdisciplinary research, and the need for an in-depth understanding of the diverse needs, competences, and power of actors and the water governance system in which knowledge co-production takes place. Further, several future research directions are identified, such as the examination of knowledge backgrounds according to the individual and collective thought styles of different actors. Together, the eight papers included in this Special Issue constitute a significant step toward a better understanding of knowledge co-production and transdisciplinarity, with a common thread for being reflective and clear about their complexity, and the political implications and risks they pose for inclusive, plural and just water research and governance.

Internet of Things (IoT) is rapidly growing and contributing drastically to improve the quality of life. Immense technological innovations and growth is a key factor in IoT advancements. Readily available low cost IoT hardware is essential for continuous adaptation of IoT. Advancements in IoT Operating System (OS) to support these newly developed IoT hardware along with the recent standards and techniques for all the communication layers are the way forward. The variety of IoT OS availability demands to support interoperability that requires to follow standard set of rules for development and protocol functionalities to support heterogeneous deployment scenarios. IoT requires to be intelligent to self-adapt according to the network conditions. In this paper, we present brief overview of different IoT OSs, supported hardware, and future research directions. Therein, we provide overview of the accepted papers in our Special Issue on IoT OS management: opportunities, challenges, and solution. Finally, we conclude the manuscript.

This article is an introduction to a special issue on signal coding and compression. We begin by defining the concepts of digital coding and audiovisual signal compression. We then describe the four dimensions of coding performance: bit rate, signal quality, processing delay and complexity. We illustrate the two basic principles of audiovisual coding, removal of signal redundancy and the matching of the quantizing system to the properties of the human perceptual system, with specific recent examples of coding algorithms. We then summarize standards for, and applications of audiovisual signal compression. A fast-emerging application is the internetworking of audiovisual information, a field that is too recent to be covered in the articles in this collection. We conclude our article by presenting our views about future research directions in the field.

Abstract Nonverbal vocal aspects of communication, often related to affective states, are crucial to social interactions not only for animals but also for humans during early infancy, as well as being one of the pillars of human language development and acquisition. The thread that binds together the contributions to this Special Issue is the analysis of nonverbal vocal communication during development, both from ontogenetic and phylogenetic perspectives. This introduction presents the multiple viewpoints emerging from this Special Issue and delineates future research directions for investigating the nonverbal aspects of vocal communication in early development.

This article provides an overview of 2 closely linked treatment approaches for the substance abusing client: The Community Reinforcement Approach (CRA) and Community Reinforcement and Family Training (CRAFT). In 1973, Hunt and Azrin created CRA in an attempt to restructure an individual’s “community” so that a sober lifestyle was more rewarding than one dominated by alcohol. One salient CRA premise was that an individual’s substance abuse recovery was heavily influenced by his or her social and occupational environment. Sisson and Azrin (1986) later built upon this premise in their work with a new type of client; the loved one of an alcoholic individual who refused to enter treatment. This program was an early version of CRAFT, which is an intervention that works through a nonusing individual to affect the behavior of a substance abuser. This article provides an empirical review of the evolution of these 2 interventions, including their application to illicit drug using clients. It also outlines the clinical procedures that comprise CRA and CRAFT, and considers future research directions.
