St. Patrick’s Roman Catholic Church and churchyard, Toxteth, Liverpool, UK, is the focus of community efforts to research and conserve the heritage asset, and archaeologists at the University of Liverpool were invited to contribute their expertise to co-produce new understandings of this locally significant place. Roman Catholic vault burial in Britain has not previously been archaeologically investigated, and the use of rock-cut burial pits, visible in the churchyard, appeared to be a response to the massive demand for urban burial during the nineteenth century. The project has combined local knowledge with surface survey and recording memorials in the churchyard, mapping the crypt and recording the interior of the four vaults at the western end of the crypt after they had been temporarily opened by the community volunteers. This enabled standard and photogrammetric recording, and PXRF analysis of the in-situ coffin fittings. No human remains were revealed. Interviews with volunteers and key stakeholders at the church provided the community’s voice, presented here. This project demonstrates how collaboration enables the skills and abilities of specialists, students and the local community to combine to create new knowledge and enhance public understanding of local heritage, with academically important and locally empowering results.

Widespread use of small unmanned aircraft systems is becoming prominent in the US. From structural health monitoring to journalism, small unmanned aerial systems (sUAS) are allowing people to gain a view of their surroundings and conduct their jobs in ways like never before. With this come many ethical concerns that must be addressed before the sight of a sUAS flying overhead is a widely acceptable occurrence to a majority of the population. Currently, UAS operations used in civil airspace are governed by the Federal Aviation Administration (FAA) Part 107 rules, but these regulations do not address certain ethical considerations. This paper will use the concept of a value model to quantify these ethical concerns so that they may be encoded into the design of a UAS and evaluation of missions before the missions are conducted. This could prove valuable in addressing the ethical challenges that are faced when implementing unmanned aerial systems (UAS) operations into the airspace, especially when UASs are in airspace in densely populated areas.

In recent years, the use of UAS (Unmanned Aerial Systems) has moved beyond the realm of military operations and has made its way into the hands of consumers and commercial industries. Although the applications of UAS in commercial industries are virtually endless, there are many issues regarding their operations that need to be considered before these valuable pieces of equipment are allowed for widespread civil use. Currently, UAS operations in the public domain are guided and controlled by the FAA Part 107 rules after overwhelming public pressure caused by the earlier 333 exemption. In order to approach such larger issues, this paper will exploit the use of value models, which will help to quantify how the different environmental and operational scenarios play a role in UAS operations based on the task being performed. The primary aim of this research is to use the attributes from key factors of the UAS such as the autonomy levels (AL) and technology readiness levels (TRL) along with their operating scenario factors, such as the environmental complexity and task complexity, based on the operating environment in which a UAS performs its task. To analyze the performance of autonomous UAS in different operational scenarios, the physical characteristics and class of a UAS may be linked to its AL and TRL. Using these parameters, the risks faced by the UAS in a particular mission are quantified and a value is assigned to the abstract entities involved. Although there are many critical questions with respect to good practices to be followed by UAS operators in order to obtain valuable data and information on the structures being scanned and monitored, there are many other challenges with regards to large scale operations of UAS such as the ethical, legal and societal implications that have to be addressed.
