Abstract From their first arrival in England in 1224, the Franciscans were concerned with the treatment of ill-health for both practical and spiritual reasons. Many brothers fell sick, and their illnesses required both interpretation and treatment. Some friars practised healing on their brethren and on lay patients. This article will focus on the question of the relationship between the religious vocation of the friars and the exigencies of sickness. Little evidence survives in England in the form of administrative records. But two early Franciscan writings (Tractatus de adventu fratrum minorum in Angliam, and the letters of Adam Marsh OFM, d. 1259) throw significant light on attitudes to illness and practical responses.

We consider the character of the seismic process in the Baikal and Transbaikalia regions in 2015. 36430 earthquakes with KR≥3 were recorded by seismic stations of permanent and temporary networks during the year due to the sharp increase of a number of seismic events at the north-east of the study region in the area of the large Muyakan seismic activation. 53 earthquakes were felt in the cities, towns and local settlements with an intensity not exceeding 6. The largest Tallaysk earthquake (KR=14.0, Mw=5.1) occurred at the North-Muya Ridge and was followed by few aftershocks. Focal mechanisms were determined for 118 seismic events from P-wave first-arrival polarities and based on seismic moment tensors inverted from the surface wave data. It has been found, that normal faults are realized in the sources of 49 % of earthquakes with the obtained focal mechanisms.

<p>The approximately 18,000 imperial troops who arrived in New Zealand with the British regiments between 1840 and 1870 as garrison and combat troops, did not do so by choice. However, for the more than 3,600 non-commissioned officers and rank and file soldiers who subsequently discharged from the army in New Zealand, and the unknown but significant number of officers who retired in the colony, it was their decision to stay and build civilian lives as soldier settlers in the colony. This thesis investigates three key themes in the histories of soldiers who became settlers: land, familial relationships, and livelihood. In doing so, the study develops an important area of settler colonialism in New Zealand history. Discussion covers the period from the first arrival of soldiers in the 1840s through to the early twentieth century – incorporating the span of the soldier settlers’ lifetimes. The study focuses on selected aspects of the history of nineteenth-century war and settlement.  Land is examined through analysis of government statutes and reports, reminiscences, letters, and newspapers, the thesis showing how and why soldier settlers were assisted on to confiscated and alienated Māori land under the Waste Lands and New Zealand Settlement Acts. Attention is also paid to documenting the soldier settlers’ experiences of this process and its problems. Further, it discusses some of the New Zealand settlements in which military land grants were concentrated. It also situates such military settlement practices in the context of the wider British Empire.  The place of women, children, and the regimental family in the soldier settlers’ New Zealand lives is also considered. This history is explored through journals, reminiscences, biography and newspapers, and contextualised via imperial and military histories. How and where men from the emphatically male sphere of the British Army met and married women during service in New Zealand is examined, as are the contexts in which they lived their married lives. Also discussed are the contrasting military and colonial policies towards women and marriage, and how these were experienced by soldier settlers and their families.  Lastly, the livelihood of soldier settlers is explored – the thesis investigating what sort of civilian lives soldier settlers experienced and how they made a living for themselves and their families. Utilising newspapers, reminiscences, biography, and government records the diversity of work army veterans undertook in the colony is uncovered. Notable trends include continued military-style roles and community leadership. The failed farming enterprise is also emphasised. Going further, it offers analysis of the later years of life and the different experiences of soldier settlers in their twilight years, particularly for those with and without family networks in the colony. The thesis challenges the separation between ‘war’ and ‘settlement’ by focusing on a group whose history spanned both sides of the nineteenth-century world of colony and empire.</p>

Collective psychological ownership as a sense that a territory belongs to a group might explain attitudes of the White majority toward territorial compensation for Indigenous Peoples in settler societies. Ownership can be inferred from different general principles and we considered three key principles: autochthony (entitlements from first arrival), investment (entitlements from working the land), and formation (primacy of the territory in forming the collective identity). In two studies, among White Australians (Study 1, N = 475), and White South Africans (Study 2, N = 879), we investigated how support for these general principles was related to perceived ingroup (Anglo-Celtic/White South African) and outgroup (Indigenous Australian/Black South African) territorial ownership, and indirectly, to attitudes toward territorial compensation for the Indigenous outgroup. Endorsement of autochthony was related to stronger support for territorial compensation through higher perceived outgroup ownership, whereas investment was related to lower support through higher perceived ingroup ownership. Agreement with the formation principle was related to stronger support for compensation through higher outgroup ownership, and simultaneously to lower support through higher ingroup ownership.

Gradient based traveltime tomography, which aims to minimize the difference between modeled and observed first arrival times, is a highly non-linear optimization problem. Stabilization of this inverse problem often requires employing regularization. While regularization helps avoid local minima solutions, it might cause low resolution tomograms because of its inherent smoothing property. On the other hand, although conventional ray-based tomography can be robust in terms of the uniqueness of the solution, it suffers from the limitations inherent in ray tracing, which limits its use in complex media. To mitigate the aforementioned drawbacks of gradient and ray-based tomography, we approach the problem in a completely novel way leveraging data-driven inversion techniques based on training deep convolutional neural networks (DCNN). Since DCNN often face challenges in detecting high level features from the relatively smooth traveltime data, we use this type of network to map horizontal changes in observed first arrival traveltimes caused by a source shift to lateral velocity variations. The relationship between them is explained by a linearized eikonal equation. Construction of the velocity models from this predicted lateral variation requires information from, for example, a vertical well-log in the area. This vertical profile is then used to build a tomogram from the output of the network. Both synthetic and field data results verify that the suggested approach estimates the velocity models reliably. Because of the limited depth penetration of first arrival traveltimes, the method is particularly favorable for near-surface applications.

An uncertain random variable is a tool used to research indeterminacy quantities involving randomness and uncertainty. The concepts of an ’uncertain random process’ and an ’uncertain random renewal process’ have been proposed in order to model the evolution of an uncertain random phenomena. This paper designs a new uncertain random process, called the uncertain random delayed renewal process. It is a special type of uncertain random renewal process, in which the first arrival interval is different from the subsequent arrival interval. We discuss the chance distribution of the uncertain random delayed renewal process. Furthermore, an uncertain random delay renewal theorem is derived, and the chance distribution limit of long-term expected renewal rate of the uncertain random delay renewal system is proved. Then its average uncertain random delay renewal rate is obtained, and it is proved that it is convergent in the chance distribution. Finally, we provide several examples to illustrate the consistency with the existing conclusions.

It can be challenging to pick high quality first arrivals on noisy seismic datasets. The stability and smoothness criteria of the picked first arrival are not satisfied for datasets with shingles and interferences from unexpected and backscattered events. To improve first arrival picking, we propose an automatic first arrival picking workflow using global path tracing to find a global solution for first arrival picking with the condition of smoothness of the traced path. The proposed methodology is composed of data preconditioning, global path tracing, and final addition of traced and piloted travel times to compute the total picked travel time. We propose several ways to precondition the dataset, including the use of amplitude and amplitude ratio with and without a pilot. 2D global path tracing is comprised of two steps, namely, accumulation of energy on the potential path and backtracking of the optimal path with a strain factor for smoothness. For higher dimensional datasets, two strategies were adopted. One was to split the higher-dimension data into sub-domains of two dimensions to which 2D global path tracing was applied. The alternative method was to smooth the preconditioned dataset in directions except for the one used to trace the path before applying 2D global path tracing. Next, we discussed the importance of choosing proper parameters in both data preconditioning and constraining global path tracing. We demonstrated the robustness and stability of the proposed automatic first arrival picking via global path tracing using synthetic and field data examples.
