This study assesses whether this ClaimReview data can be gainfully compiled and analysed in order to provide relevant new insights into the “fact-checking movement”. After discussing the methodology used to compile and analyse the research dataset, the key global findings from the database analysis are presented. Next, potential limitations of the research dataset are considered, before assessing how the current study contributes to the academic knowledge on fact-checking and the fact-checking movement.

The in-depth recording of ship timbers is a process which is both challenging and laborious, but it is an indispensable step in order to fully understand the construction of the ship the timbers formed a part of, and as archaeologists it is our duty to document all the information these complex artefacts hold to the best of our abilities. In this article, the authors first provide an overview of the methods currently in use for ship timber recording, namely 2D scaled drawing, 2D tracing, 3D contact digitising and 3D scanning. The respective advantages and limitations of these methods are then discussed in light of the various scientific and practical considerations that go into choosing a recording method for a project. Next, a new approach to ship timber recording, termed the “3D annotated scans method”, is introduced and discussed using a recent case study in northern Germany. At its core the method consists of two phases; a 3D scanning phase in which the timber is scanned in 3D, followed by a 3D annotation phase in which the recorder interprets the timber by tracing diagnostic features such as fasteners and toolmarks directly onto the timber’s digital model. The authors conclude that this new approach represents an improvement over current methods—both in terms of the quality of the scientific outputs and in terms of recording efficiency—and that, besides being implemented for the recording of ship timbers, the same method can also be used for a wide range of other heritage applications.

In this master thesis I explore the potential of this innovative new technology for underwater archaeological site recording.
In the introductory chapter I first discuss the importance of archaeological site recording, as well as the importance of exploring new and perhaps better ways of documenting our heritage. I then stress that for a new recording method to see widespread use within the field of maritime archaeology, it must offer distinct advantages over traditional manual recording methods, but it must also be accessible, both in terms of costs and in terms of the technical expertise required to use the method. I believe Computer Vision Photogrammetry could meet these requirements, and as such I think the method is worth investigating further.
In the second chapter I then provide readers with the necessary background information in order to understand what photogrammetry actually is, how it works, and how it has evolved from the 19th century to the present day. Special focus is put on the new generation of Computer Vision Photogrammetry techniques, and on explaining what sets these techniques apart from photogrammetry approaches used in the past.
Next, in the third chapter I have a closer look at past uses of photogrammetry in underwater archaeology. Photogrammetry has been used for underwater archaeological site recording for several decades now, in some cases as early as the 1960s. Nevertheless, the method has never broken through as a mainstream recording method within our discipline. My literature review demonstrates that while photogrammetry had significant advantages over traditional manual recording methods, in the past the method was too technical, too expensive and too unreliable for most archaeological projects.
For the remainder of my dissertation the challenge is therefore to assess whether modern Computer Vision Photogrammetry can successfully overcome these past obstacles. In order to draw some well-founded conclusions, I want to use Computer Vision Photogrammetry software to process a number of archaeological case studies. As a first step, in the fourth chapter I therefore attempt to make an informed decision on which specific photogrammetry software to use to process these case studies. After testing various software packages, and after assessing the relevant scientific literature, my software of choice is Agisoft PhotoScan.
In the next chapter PhotoScan is then used to process data from three archaeological shipwreck sites. The intention is to really test the reliability and flexibility of modern photogrammetry and as such, rather than using ‘perfect’ picture sequences, my case studies focus on the use of particularly challenging or unconventional input data. In the first case study a shipwreck is modelled from ‘casual’ video footage that was not originally captured for photogrammetry purposes. In the second case study a three-dimensional model is created using ‘legacy data’; archived pictures originally taken more than 20 years ago. In the final case study a shipwreck is modelled using images captured in a low-visibility environment. In each case study the site is first briefly introduced, the main challenges of the specific dataset are then outlined, next the processing procedure is discussed and finally the results are presented.
In the sixth chapter I then discuss the results of these case studies as a whole, and attempt to draw some conclusions regarding the overall impact of new developments in photogrammetry on our discipline over time.
I conclude that compared to traditional manual recording methods, Computer Vision Photogrammetry is capable of significantly reducing underwater recording times while simultaneously producing more accurate, more detailed and more objective three-dimensional results. Furthermore, compared to past photogrammetry approaches, today Computer Vision Photogrammetry is more affordable, easier to use, more time-efficient and more reliable. Thanks to the confluence of a) reduced costs and b) increased performance, I believe a ‘tipping point’ has finally been reached. For most underwater archaeological projects the cost of using photogrammetry will now actually be lower than the cost of using manual recording methods. Considering the fact that photogrammetry also produces better results than manual recording methods, we have every reason to believe that Computer Vision Photogrammetry will play an increasingly prominent role in the field of underwater archaeology in the years to come.

In this article, I share my experience in working with one such software package, namely PhotoScan, to record a Dutch shipwreck site. In order to demonstrate the method’s reliability and flexibility, the site in question is reconstructed from simple GoPro footage, captured in low-visibility conditions. Based on the results of this case study, Computer Vision Photogrammetry compares very favourably to manual recording methods both in recording efficiency, and in the quality of the final results. In a final section, the significance of Computer Vision Photogrammetry is then assessed from a historical perspective, by placing the current research in the wider context of about half a century of successful use of Analytical and later Digital photogrammetry in the field of underwater archaeology. I conclude that while photogrammetry has been used in our discipline for several decades now, for various reasons the method was only ever used by a relatively small percentage of projects. This is likely to change in the near future since, compared to the ‘traditional’ photogrammetry approaches employed in the past, today Computer Vision Photogrammetry is easier to use, more reliable and more affordable than ever before, while at the same time producing more accurate and more detailed three-dimensional results.

- Supporting evidence for J. Janick's (2007) conclusion that the aromatic substance referred to in ancient Egyptian sources as "anti", is not Myrrh (as is the prevailing assumption in current literature), but more likely derives from the Boswellia genus of trees.
- The first full reconstruction of the relief depicting Queen Hatshepsut's Punt Expedition, found at her funerary complex in Deir el-Bahari. The reconstruction in this paper combines extensive drawings of the relief by Howard Carter and Percy Brown made during Édouard Naville's expedition to Deir el-Bahari (1898), with hieroglyphic texts recovered by Kurt Sethe (1905), a missing fragment published by Nicholas Millet (1962) and a reconstruction of the damaged southern sidewall by William Smith (1962).

In response to these difficult circumstances two innovations were introduced: the sjægt (a new type of fishing vessel) and Danish seine fishing. Through case studies this paper examines the historical background and impact of these important innovations in times of crisis at the Western Limfjord.

When discussing the production method of tin, focus is put on the extraction of the main tin ore, cassiterite, and on its processing from raw material to easily transportable tin ingots. The chapter on the uses of tin discusses both the applications of pure tin and the use of tin in the production of high quality bronzes. Pure tin would in rare cases be used for the making of artefacts, but was more commonly used as a coating, a solder or a means of payment. However, the most important application of tin was undoubtedly its alloying with copper to form bronze. The advantages of bronze over copper are discussed, as well as the transition from earlier arsenical bronze to tin bronze. Finally the provenance of tin in the Near East is examined and the writer concludes that, with the emergence of new geological and archaeological data, this issue might not be as complicated as previously imagined. A map composed from information from numerous different articles shows the newly discovered tin mineralizations in the Near East and reinforces the theory that tin was first locally exploited before being imported from Central Asia.

This presentation discusses a novel, time-efficient approach for the 3D scanning and interpretation of archaeological ship timbers.
In summary, we 1) use an Artec structured light scanner to produce a textured 3D mesh of the timbers in question, we then 2) annotate and interpret these scans in Rhino, before finally 3) producing an automated 2D timber catalogue of all timbers.
When compared to the current best-practice method for timber recording (FaroArm recording / contact digitising) we find that our "Annotated Scans Method" is much more cost-efficient, while simultaneously producing outputs that are as good and in some regards better than the current best-practice.
