Mars is a planet of great interest in the search for signatures of past or present life beyond Earth. The years of research, and more advanced instrumentation, have yielded a lot of evidence which may be considered by the scientific community as proof of past or present habitability of Mars. Recent discoveries including seasonal methane releases and a subglacial lake are exciting, yet challenging findings. Concurrently, laboratory and environmental studies on the limits of microbial life in extreme environments on Earth broaden our knowledge of the possibility of Mars habitability. In this review, we aim to: (1) Discuss the characteristics of the Martian surface and subsurface that may be conducive to habitability either in the past or at present; (2) discuss laboratory-based studies on Earth that provide us with discoveries on the limits of life; and (3) summarize the current state of knowledge in terms of direction for future research.

With the aim to take advantage from the existing technologies in microelectronics, photodetectors should be realized with materials compatible with them ensuring, at the same time, good performance. Although great efforts are made to search for new materials that can enhance performance, photodetector (PD) based on them results often expensive and difficult to integrate with standard technologies for microelectronics. For this reason, the group IV semiconductors, which are currently the main materials for electronic and optoelectronic devices fabrication, are here reviewed for their applications in light sensing. Moreover, as new materials compatible with existing manufacturing technologies, PD based on colloidal semiconductor are revised. This work is particularly focused on developments in this area over the past 5–10 years, thus drawing a line for future research.

Measuring flows of aerosol particles of less than 10 μm diameter has proven a challenge in the past. Previously, our work included a brief review of the current state-of-art for aerosol measurements where accurate sizing was limited to particles greater than 5 μm. We developed a sizing and positioning algorithm (SPA) to accurately calculate both the diameter of a spherical particle, and the relative position of that particle to the object plane of the imaging camera for particles down to 3 μm in diameter. Our current work further extends the measurement range down to 1 μm particles. This algorithm has great benefit for the scientific community interested in small-particle aerosol flows.

The purpose of this review is to characterize major advancements in the past 40 years of research on youth sport motivation. The author focuses on this period, during which the Institute for the Study of Youth Sports, affiliated researchers, and other scholars contributed to the current state of the field. First, she traces paradigm shifts that represent changes in the philosophy and practice of science in youth sport motivation research. Second, she discusses emergent theoretical perspectives that guided empirical research and produced robust findings on predictors, mediators, and outcomes of motivation. Third, she translates these theories and associated studies to inform evidence-based best practices for youth sport programs. Finally, the author recommends that future research highlight developmental approaches, examine sport as a means of promoting physical activity, and consider multidisciplinary perspectives on conducive topics. By reflecting on paradigm shifts and research trends over time, scholars can meaningfully contribute to an increased understanding of youth sport motivation in the decades to come.

Purpose The purpose of this paper is to provide a broad preliminary overview and critical viewpoint on the current state of customer experience innovation and strategy in Thailand. Design/methodology/approach This paper outlines and critically analyses the key trends based on 15 prime instances of customer experience innovation from the past ten years in Thailand across three industries: retail, fuel service and insurance. Findings Customer experience in Thailand is still in its nascent stage. This is because firms are yet to realise their full potential as critical brand differentiators. Many Thai firms also miss collaboration opportunities with external partners when innovating customer experiences. This is despite the overwhelming contributions from local SMEs to breakthrough innovations and creativity. Consequently, many customer experience innovations in Thailand are yet to be truly memorable and unique. Originality/value This is the first paper that critically examines the trends in customer experience across the retail, fuel service and insurance. It is also the only paper that outlines strategic implications of customer experience strategies and innovations to date for Thailand. Both future research topics and managerial implications for Thai professionals are discussed in the paper.

Murder Victims

Over the past 25 years, homicide researchers have largely ignored older adults. This pattern continues even in light of the ongoing demographic shift associated with the aging baby boomer generation. This article reflects on the current state of the literature and discusses areas in need of attention. Future research needs can be categorized into substantive and methodological issues. The insights gained by exploring these topics can generate nuanced explanations for fatal violence against older adults and support future evidence-based prevention policies.

Scholarly Attention

For international and domestic actors, postconflict situations constitute one of the most difficult policy arenas to understand and operate within. In this context, the sustainable management of natural resources to prevent conflict and build peace—before, during, or after conflict—has received increasing scholarly attention over the past three decades. Emphasizing the potential for environmental cooperation to support peace and stability, researchers have focused on the ecological foundations for a socially, economically, and politically resilient peace. This chapter takes stock of the current state of the art on environmental peacebuilding, providing a summary of the most common definitions before looking back at the development of environmental peacebuilding along the two most noticeable perspectives and the remaining challenges and pathways for future research.

Service Profit Chain

Over the past 25 years, the service–profit chain (SPC) has become a prominent guidepost for service managers and researchers. In this article, we reflect on and synthesize published research to clarify what researchers have learned about the SPC and what remains less well understood. Based on an in-depth discussion of the field, we present a revised SPC and propose multiple areas in which further research would be worthwhile, such as internal service quality as specific systems of human resource management practices, both employee and customer well-being as additional mediators, different targets of employee and customer loyalty, contingencies, and non-linear and feedback effects. We conclude by reimagining the SPC, and we discuss digital and artificial-intelligence–driven changes to the SPC’s structure. Finally, based on the insights we discuss, we inform scholars of the current state of SPC research and provide a detailed agenda for future research.

The ontogeny of macrophages in most organs has already been established. Owing to the limited number and inaccessibility of synovial macrophages (SMs), the origin of SMs has not been fully elucidated. Previous studies suggested that SMs have two major origins, namely, tissue-resident and monocyte-derived SMs. However, no systematic analysis to identify SM ontology in either physiological or pathological conditions has been available to date. In this review, we summarize relevant studies on the two main origins of SMs in rheumatoid arthritis (RA) and forecast the future research directions for this field. Furthermore, we discuss the current state of RA therapy that is based on targeting different SM subsets.

Learning Architectures

Over the past decade deep learning has driven progress in 2D image understanding. Despite these advancements, techniques for automatic 3D sensed data understanding, such as point clouds, is comparatively immature. However, with a range of important applications from indoor robotics navigation to national scale remote sensing there is a high demand for algorithms that can learn to automatically understand and classify 3D sensed data. In this paper we review the current state-of-the-art deep learning architectures for processing unstructured Euclidean data. We begin by addressing the background concepts and traditional methodologies. We review the current main approaches, including RGB-D, multi-view, volumetric and fully end-to-end architecture designs. Datasets for each category are documented and explained. Finally, we give a detailed discussion about the future of deep learning for 3D sensed data, using literature to justify the areas where future research would be most valuable.
