Abstract: In a research project, i3mainz has installed a number of different test targets that allow an investigation in the quality of measurements obtained with laser scanners. The standardized tests, carried out since 2003, also allow a comparison between instruments of different manufacturers for the first time. The test procedures include scans of plane surfaces of different reflectivity in different ranges to obtain information about the noise of the range measurements and about systematic offsets caused by different materials. Several test fields using white spheres as targets have been installed to get information about the accuracy of distances in scanning direction and across. Due to different angular increments and spot sizes, not all 3D scanners have the same abilities to resolve small object details. 3D scanners are also known to produce errors at edges. Both phenomena are tested with appropriate targets. The tests are still available and producers and users are invited to have their instruments examined.

TL;DR: The concept of the Palaeoanthropocene as discussed by the authors recognizes that humans are an integral part of the Earth system rather than merely an external forcing factor, and proposes the term to recognize the Anthropocene as a new epoch of geological time.

TL;DR: In this article, the advantages and disadvantages of combining 3D scanning and photogrammetry for heritage documentation are investigated. And the authors give users (especially those who are not surveying experts) recommendations, which method is suited best for what kind of application, or even if a combination of 3D scanners and photograms is advisable.
Abstract: There is a high demand in documentation of cultural heritage objects such as artifacts, sculptures or buildings. In the past years, laser scanning, or 3D scanning in general, has been used increasingly for cultural heritage recording and the question arose if this new method can replace traditional methods like close-range photogrammetry. To investigate the advantages and disadvantages of both methods, i3mainz has carried out some case studies for cultural heritage documentation. Different typical objects were chosen and characteristical parts of them were recorded both by photogrammetry and scanning. Documented objects include an archaeological stone wall, baroque relief plates, Stone Age artifacts, ancient statues and the facade of a classical castle. Besides 3D scanning all these examplary objects were also recorded with standard stereophotogrammetry which is the most popular heritage recording method so far. Results are usually line drawings, but the creation of orthophotos or digital surface models is possible, too. In this paper five case studies are shortly introduced and the results of both measurement techniques are presented and compared. The aim is to give users (especially those who are not surveying experts) recommendations, which method is suited best for what kind of application, or even if a combination of 3D scanning and photogrammetry is advisable. Criteria like quality of the results, amount of cost and time, required equipment and occurring problems are to be considered.

TL;DR: In this article, the authors explored the social capabilities of social entrepreneurs and illustrative cases with the purpose of elaborating RBV toward a social resource-based view (SRBV) of the firm.
Abstract: While the economic and environmental dimensions of the triple bottom line (TBL) have been covered extensively by management theory and practice, the social dimension remains largely underrepresented. The resource-based view (RBV) of the firm and the natural resource-based view (NRBV) of the firm are revisited to lay the theoretical foundation for exploring how the social dimension might be addressed. Social capabilities are then explored by looking at the social entrepreneurship literature and illustrative cases with the purpose of elaborating RBV toward a social resource-based view (SRBV) of the firm. Three illustrative cases, which represent social businesses located in catastrophe-ridden Haiti, show how capabilities are used to overcome challenging constraints. The goal for the social entrepreneur is to employ the appropriate capabilities to ensure economic success, a positive environmental impact, and social benefits that leave the local community in a better position than without the business. Just as NRBV is a previous elaboration of RBV, so can SRBV be an elaborated theoretical foundation for future research. The components of a theory are systematically addressed by extending the range of variables (adding social capabilities), extending the domain (including stakeholders with economic, environmental, and/or social stakes), and offering propositions on variable relationships and outcome predictions (linking social capabilities and shared TBL value creation). By highlighting the social capabilities of social entrepreneurs, this research illuminates the micro-foundations of corporate social responsibility, emphasizing the value of individual level analyses.

TL;DR: In this paper, the authors employ a unique data set of approximately 1000 mergers to analyze the determinants of bank mergers and find that improving financial profiles lower the likelihood of distressed mergers more than the likelihood for non-distressed mergers.
Abstract: Most bank merger studies do not control for hidden bailouts, which may lead to biased results. In this study we employ a unique data set of approximately 1000 mergers to analyze the determinants of bank mergers. We use undisclosed information on banks' regulatory intervention history to distinguish between distressed and non-distressed mergers. Among merging banks, we find that improving financial profiles lower the likelihood of distressed mergers more than the likelihood of nondistressed mergers. The likelihood to acquire a bank is also reduced but less than the probability to be acquired. Both distressed and non-distressed mergers have worse CAMEL profiles than non-merging banks. Hence, non-distressed mergers may be motivated by the desire to forestall serious future financial distress and prevent regulatory intervention.
