Reconsidering the Geography of Tourism and Contemporary Mobility

Tourism is one of the world's largest legal industries. At the same time that tourism has grown so has its study, to the extent that there is debate as to whether it may constitute a discipline in its own right. Geographers have long contributed to the study of tourism. However, there is substantial concern over the development of the sub‐discipline and how tourism is conceptualised. A framework for understanding tourism in relation to contemporary human mobility over space and time is provided. This framework bears strong relationships to research on time geography as well as to work on diaspora and transnationalism. Some of the implications of incorporating tourism within the framework of mobility are outlined with respect to mobility as a form of capital, the relationships between different forms of mobility, and an improved understanding of tourism's impacts at all stages of the travel process rather than just at the destination.     

The origin of overpressure in 'old' sedimentary basins: an example from the Cooper Basin, Australia

Overpressure in ‘old’ sedimentary basins that have not undergone rapid, recent sedimentation cannot be easily explained using traditional burial‐driven mechanisms. The last significant burial event in the Cooper Basin, Australia, was the Late Cretaceous deposition of the Winton Formation (98.5–90 Ma). Maximum temperature in the basin was attained during the Late Cretaceous, with cooling beginning prior to 75 Ma. Hence, overpressure related to rapid burial or palaeomaximum temperatures (e.g. hydrocarbon generation) must have developed prior to 75 Ma. Retaining overpressure for 75 Ma in ‘old’ basins such as the Cooper Basin requires extremely low seal permeabilities. An alternative explanation is that overpressure in the Cooper Basin has been generated because of an increase in mean stress associated with an increase in horizontal compressive stress since Late Cretaceous times. Structural observations and contemporary stress data indicate that there has been an increase in mean stress of approximately 50 MPa between Late Cretaceous times to that presently measured at 3780 m. The largest measured overpressure in the Cooper Basin is 14.5 MPa at 3780 m in the Kirby 1 well. Hence, disequilibrium compaction driven by increasing mean stress can explain the magnitude of the observed overpressure in the Cooper Basin. Increases in mean stress (tectonic loading) may be a feasible mechanism for overpressure generation in other ‘old’ basins that have undergone a recent increase in horizontal stress (e.g. Anadarko Basin).     

An overview of bitumen trade in the Near East from the Neolithic (c.8000 BC) to the early Islamic period

The aim of the paper is to summarise the present state of knowledge concerning bitumen trade in the Near East from the Palaeolithic (70,000 BP) to the Early Islamic period. During the Palaeolithic and Early Neolithic period, bitumen utilisation was mostly concentrated in settlements close to oil seeps. From the Ubaid 3 period, bitumen from the Mosul area became more important and was traded as far as the southern Persian Gulf. The Uruk period is a turning point for Mesopotamian history as settlements evolved into city‐states. These cities had a great need for raw materials, and this marks the beginning of large‐scale exploitation of Hit bitumen. This bitumen was traded at settlements along the Euphrates, where a large trade network was established. Hit bitumen entered the Persian Gulf at the turn of the second millennium (Dilmun period). Bitumen from Iraq (Mosul and Hit) became predominantly used in most settlements along the southern coast of the Gulf. During this period Iranian bitumen was also exported and this supply tended to increase, especially during the Partho‐Sasanian period. Dead Sea bitumen had its own exchange network, which was concentrated across present‐day Israel and Egypt where it was extensively used for mummification.     

Payments for Ecosystem Services in Nicaragua: Do Market‐based Approaches Work?

The concept of Payments for Ecosystem Services (PES) is gaining increasing attention among scholars as well as conservation and development practitioners. The premises of this innovative conservation approach are appealing: private land users, usually poorly motivated to protect nature on their land, will do so if they receive payments from environmental service buyers which cover part of the land users’ opportunity costs of developing the land. However, this article warns against an over‐enthusiastic adoption of a one‐sided market‐based PES approach. Based on a field study of the Regional Integrated Silvopastoral Approaches to Ecosystem Management Project (RISEMP), one of the main PES pilot projects in Nicaragua, it suggests that a mixture of economic and non‐economic factors motivated farmers to adopt the envisaged silvopastoral practices and that the actual role of PES is mistakenly understood as a simple matter of financial incentives. The authors argue that PES approaches should be understood as a part of a broader process of local institutional transformation rather than as a market‐based alternative for allegedly ineffective government and/or community governance.     

Ossified haematomas and infectious bone changes on the anterior tibia: histomorphological features as an aid for accurate diagnosis

Examination of the histological structure of bone not only helps investigators to estimate age at death but can also aid in the diagnosis of palaeopathological lesions. The purpose of this paper is to assess whether histological features as described in the literature can confirm the macroscopic diagnoses of ossified subperiosteal haematomas associated with healed scurvy and syphilitic bone changes observed on the anterior tibiae of individuals from a 19th century mining community from Kimberley South Africa. The frequent occurrence of these two diseases amongst the deceased was well established in related hospital documents and governmental documents. A section of bone was removed from lesions on the tibiae of 14 individuals. These bone changes were macroscopically diagnosed as being indicative of either treponematosis ossified subperiosteal haematomas or non‐specific periostitis. Cross‐sections were prepared for microscopic investigation using a manual ground section technique. Ossified haematomas were histologically identified in seven individuals. These sections were characterised by normal cortical bone an intact original periosteal surface and newly formed radiating trabecular bone apposing it. Three phases of ossified subperiosteal haematoma formation and remodelling could be distinguished. Infectious bone changes most likely associated with treponematosis were observed in one individual. These were characterised by lysis and numerous resorption holes/channels. No clear distinction could be made between the internal spongy cortical or newly formed bone. Histological features described by some authors as characteristic of this condition could not be identified. In addition three individuals presented with microscopic features indicative of both the aforementioned bone affections and three did not show any pathological changes on microscopic level. It was concluded that although specific pathological conditions can most likely not be diagnosed purely on the basis of histomorphological observations broad distinctions could be made between lesions caused by the ossification of subperiosteal haematomas and bone changes due to infectious diseases.

Eagle owl (Bubo bubo) pellets from Roman Sagalassos (SW Turkey): distinguishing the prey remains from nest and roost sites

Two concentrations of animal bones, almost exclusively from small mammals and wild birds, were found within the destruction debris of a Roman bath complex in Sagalassos (SW Turkey). The overall species spectrum, skeletal element representation, fragmentation and preservation condition of the bones indicate that they represent the prey remains of a large nocturnal avian predator, more precisely the eagle owl (Bubo bubo). Differences in skeletal element representation and in prey species' spectrum show that the two bone clusters derive from pellets deposited near a nest site and a roost site, respectively. Radiocarbon dates obtained from the bones indicate that eagle owls lived in the collapsing bath complex during the second half of the 6th to the beginning of the 7th century AD, before the final abandonment of the town. The MNI of the prey animals found at the nest site, confronted with the daily dietary needs of a female eagle owl and its young, indicates repetitive use of the same place during several years.

Les fondements d’une phénoménologie de la littérature selon Jan Patočka

Le phénoménologue tchèque Jan Pato?ka, auteur d’une phénoménologie asubjective défendant la thèse d’un procès asubjectif de l’apparaître (d’une autonomie du phénomène par rapport à l’ego), a accordé au problème des relations nécessaires et difficiles que la philosophie entretient en son sein même avec la littérature une attention particulière qui l’a conduit à poser les fondements d’une phénoménologie de la littérature centrée autour de l’idée d’un asubjectivisme de l’écrivain. Nous suivrons ici deux axes de réflexion connexes: premièrement, nous montrerons pourquoi et comment Pato?ka restaure le vocabulaire et la vision de l’homme propres au mythe et reprend ce qu’il aperçoit comme le fondement de la tragédie pour élaborer une nouvelle compréhension du phénomène de l’existence comme mouvement. Deuxièmement, nous décrirons le rôle que joue l’écrivain moderne à une époque marquée par la fragmentation de la vie. Car l’écrivain qui édifie une “littérature métaphysique” a le privilège, selon Pato?ka, d’être “l’administrateur propre et originel de l’intégralité de la vie et de la totalité universelle”, il est ainsi une sorte de “quasi-phénoménologue” dont la philosophie ne peut se passer si elle veut saisir ces phénomènes qui, sans être purement et simplement subjectifs, ne peuvent néanmoins être réduits à l’objectivité du concept.     

Geomorphological setting and Native American acquisition of buff-firing ceramic clays in the Lower and Middle Gila River Valley, Arizona

This study addresses buff-firing clay sources in dynamic alluvial settings along Arizona’s Gila River in the U.S. Southwest. We establish clay resource distribution relative to the geomorphic histories of the Lower and Middle Gila River based on 38 clay samples and ethnographic data from two US Bureau of Reclamation (BOR) projects. Buff-firing clayey alluvium, deposited in the Gila River floodplain 800 to 1,500 or more years ago, was a surficial ceramic raw material source for prehistoric Hohokam and lowland Patayan potters. This geomorphic unit was later removed in some places and buried by up to 3-4 m of sediment in others, reducing the availability of buff-firing clays in the Hohokam Classic period and requiring historic Pee Posh and Akimel O’odham potters to dig pits to access it. Sources were further destroyed in catastrophic floods in the late 19th and early 20th century, affecting ceramic manufacture patterns and ultimately contributing to the decline of pottery production by the O’odham living in the Gila River Valley. Our results contribute to regional ceramic ecology and should also be of interest to others investigating alluvial clay use in general or buff-firing alluvial clays in particular. The study also illustrates the value of combining geomorphic and ethnographic data to examine major changes in resource distribution and use.     

Re‐examining the relationship between cranial deformation and extra‐sutural bone formation

The relationship between cranial deformation and the occurrence of extra‐sutural bones remains poorly understood. Scholars are divided about whether or not cranial deformation causes an increased occurrence of these bones, and even those who agree that deformation does have an influence often disagree about which locations on the crania are most impacted. Part of this issue clearly stems from the difficulties in finding appropriate samples from which to test the hypothesis that deformation leads to an increased expression of extra‐sutural bones. The present study examines the effects of fronto‐occipital and occipital‐only deformation on the occurrence of extra‐sutural bones through an analysis of 59 deformed and undeformed crania from the Philippines. Relative to the undeformed crania, both deformed samples showed an elevated number of extra‐sutural bones. Using two different statistical tests, we identified a significantly higher occurrence of extra‐sutural bones at two distinct cranial localities for both the fronto‐occipitally deformed crania (coronal suture and asterion) and for those showing only occipital flattening when compared to the undeformed crania (lambdoidal and asterion). However, as our data reveal, individuals with highly elevated occurrences of extra‐sutural bones are not necessarily deformed. As such, we argue that deformation practices may have a positive impact on the formation of extra‐sutural bones; however, future studies using larger samples of deformed and undeformed crania—ideally from the same site—will be necessary to distinguish between the influence of cranial deformation on extra‐sutural bone formation relative to other population factors which may play a role in shaping variation in this feature.
