Where do we go from here? New perspectives on the black box in strategic human resource management research

Abstract: The main objective of the present research is to briefly review the strategic human resource management (HRM) literature from multilevel theoretical perspectives to summarize what we know about mediating mechanisms in the HR�performance relationship. By doing so, we highlight future research needs to advance theoretical understanding of the �black box� in strategic HRM research. Furthermore, by offering additional theoretical perspectives that can be used to understand the mediating mechanisms at different levels, we suggest future research directions that capture the complexities associated with strategic HRM through a multilevel theoretical lens. Implications of the model are discussed.

Generic Atmospheric Correction Model for Interferometric Synthetic Aperture Radar Observations

Abstract: For mapping Earth surface movements at larger scale and smaller amplitudes, many new synthetic aperture radar instruments (Sentinel-1A/B, Gaofen-3, ALOS-2) have been developed and launched from 2014–2017, and this trend is set to continue with Sentinel-1C/D, Gaofen-3B/C, RADARSAT Constellation planned for launch during 2018–2025. This posesmore challenges for correcting interferograms for atmospheric effects since the spatial-temporal variations of tropospheric delay may dominate over large scales and completely mask the actual displacements due to tectonic or volcanic deformation. To overcome this, we have developed a generic interferometric synthetic aperture radar atmospheric correction model whose notable features comprise (i) global coverage, (ii) all-weather, all-time useability, (iii) correction maps available in near real time, and (iv) indicators to assess the correction performance and feasibility. The model integrates operational high-resolution European Centre for Medium-Range Weather Forecasts (ECMWF) data (0.125° grid, 137 vertical levels, and 6-hr interval) and continuous GPS tropospheric delay estimates (every 5 min) using an iterative tropospheric decomposition model. The model’s performance was tested using eight globally distributed Sentinel-1 interferograms, encompassing both flat and mountainous topographies, midlatitude and near polar regions, and monsoon and oceanic climate systems, achieving a phase standard deviation and displacement root-mean-square (RMS) of ~1 cm against GPS over wide regions (250 by 250 km). Indicators describing the model’s performance including (i) GPS network and ECMWF cross RMS, (ii) phase versus estimated atmospheric delay correlations, (iii) ECMWF time differences, and (iv) topography variations were developed to provide quality control for subsequent automatic processing and provide insights of the confidence levelwithwhich the generated atmospheric correctionmapsmaybe applied.

Explaining the Political Ambivalence of Religion

Abstract: This essay takes on the broad question - what explains the political pursuits of religious actors? - by exploring two powerful influences on these pursuits. The first is differentiation, or the degree of autonomy between religious actors and states in their basic authority. The second is political theology, the set of ideas that religious actors hold about political authority and justice. Through global comparisons across religions, regions, and states, it seeks to establish the effect of both influences on two political pursuits in which religion’s role is hotly debated today: support for democratization and political violence, including communal violence and terrorism. It concludes with lessons learned commonly from the analysis of both pursuits.

Overvaluation and the Choice of Alternative Earnings Management Mechanisms

Abstract: In this study I examine how the degree and duration of overvaluation affect management's use of alternative within-GAAP earnings management, restrictions on further exploitation of within-GAAP accruals management, and subsequent non-GAAP earnings management Further, I examine how one type of earnings management segues into another type as overvaluation persists I present evidence that the longer the firm is overvalued, the greater is the amount of total earnings management I also find that managers engage in accruals management in the early stages of overvaluation before moving to real transactions management, in order to sustain their overvalued equity Finally, I find that the longer a firm is overvalued, the more likely it is to engage in one of the most egregious forms of earnings management, non-GAAP earnings management Collectively, the results suggest that the duration of firm overvaluation is an important determinant of managements' choice of alternative earnings management mechanisms

Development environments for autonomous mobile robots: A survey

Abstract: Robotic Development Environments (RDEs) have come to play an increasingly important role in robotics research in general, and for the development of architectures for mobile robots in particular. Yet, no systematic evaluation of available RDEs has been performed; establishing a comprehensive list of evaluation criteria targeted at robotics applications is desirable that can subsequently be used to compare their strengths and weaknesses. Moreover, there are no practical evaluations of the usability and impact of a large selection of RDEs that provides researchers with the information necessary to select an RDE most suited to their needs, nor identifies trends in RDE research that suggest directions for future RDE development. This survey addresses the above by selecting and describing nine open source, freely available RDEs for mobile robots, evaluating and comparing them from various points of view. First, based on previous work concerning agent systems, a conceptual framework of four broad categories is established, encompassing the characteristics and capabilities that an RDE supports. Then, a practical evaluation of RDE usability in designing, implementing, and executing robot architectures is presented. Finally, the impact of specific RDEs on the field of robotics is addressed by providing a list of published applications and research projects that give concrete examples of areas in which systems have been used. The comprehensive evaluation and comparison of the nine RDEs concludes with suggestions of how to use the results of this survey and a brief discussion of future trends in RDE design.
