The Phoenicians and the Ocean: trade and worship at La Caleta,Cadiz, Spain

The area of La Caleta, north‐west of Cadiz, is a key location for studies of the relationship between the Phoenician city of Gadir and the ocean. The port channel and the small islets that characterize the area was one the busiest sectors of the city, and there are abundant underwater remains attesting to past commercial activities. The area also had an important religious role: two sanctuaries were located at the western end of the rocky promontories that surround the channel, and many items identified as offerings have been found. This article synthesizes previous research and provides an overview of the results of a recent project (2008–2010), which enables a thorough review of the development of the seascape and its use during the 1st millennium BC.     

Fish and Fish Products in Late Antique Palestine and Babylonia in Their Social and Geographical Contexts: Archaeology and the Talmudic Literature

This paper looks at the ancient Jewish talmudic literature (4th-7th centuries CE) for information about fish and fish products in the ancient world and compares it with information from classical sources and from archaeology. Analysis of the texts show that information about food, and particularly fish and fish products, can be derived from texts originally written as religious regulations and moral narratives. Talmudic textual evidence, backed up by parallel archaeological finds, documents long-distance transport of preserved fish, including what is identified as Nile perch from Egypt and mackerel from Spain. Parallel papyrological evidence testifies to the import of the parrot wrasse. Graeco-Roman allec, a sauce made of macerated tiny fish, is identified by the Palestinian Talmud with tarit terufah, made of tiny chopped fish, and afitz, cf Greek afye, immature fish, often cooked as such. Remains of allec have been found archaeologically in Israel/Palestine. The Palestinian Talmud identifies tarit[a] with tza?ana, one of a trio of strong-smelling Babylonian fish-dishes eaten by the poor: the others are gildana and harsana. The varied material on these discussed here adds to our knowledge of ancient salted and/or fermented fish-dishes. The identification of tza?ana with 9th-to-10th century ?a?na from Baghdad of the Caliphs and 14th-century Cairo appears very likely. Thus tarit/tza?ana/?a?na appears to have been not very appetising processed fish food for the poor in Roman Palestine, Jewish Babylonia, Baghdad of the Abbasid Caliphs and Mamluk Egypt, and it may be identified with allec. The talmudic literature also discusses reasons for failure of the preservation processes, as well as of potentially lethal effects of insufficient preservation.     

Truth-Telling in the Wake of European Contact: Historical Investigation of Aboriginal Skeletal Remains from Normanton

This study heeds the call for a ‘truth-telling’ of injustices carried out on Aboriginal communities during the colonial acquisition of Australia as stated in the Uluru Statement from the Heart 2017. Here, we discuss the lives of eight Indigenous people buried in Normanton in north-west Queensland (QLD) who died and had their remains collected in the late 1890s as scientific specimens. The remains were later repatriated to the community before being further exposed by erosion in 2015. With the consent and participation of local traditional owners—the Gkuthaarn and Kukatj people—this assessment utilised bioarchaeological, historical and anthropological methodologies to gain a better understanding of Indigenous life and health on the Australian colonial frontier. Gkuthaarn and Kukatj people were engaged throughout the investigation, and statements throughout this piece made by them illustrate how bioarchaeology can inform on past injustices in Australia’s history, bringing them into the public consciousness and aiding the transition to reconciliation through ‘truth-telling’.     

Political Commitment,Policy Ambiguity,and Corporate Environmental Practices

A lack of clear political commitment together with confusing rules and enforcement often characterize the institutional context of policy implementation and regulatory compliance in developing countries. By connecting such contextual features to existing models of policy implementation and regulatory compliance, we examine how regulatory factors are related to basic and proactive corporate environmental management practices in the Pearl River Delta region in China. Drawing on data derived from both a survey and in‐depth interviews, we show that a perception of clear political commitment to environmental protection across multiple government levels and units is positively associated with business efforts in basic environmental practices, regardless of the specific enforcement intensity. Nevertheless, a perception of clear political commitment is not related to proactive environmental practices. Conversely, a perception of policy ambiguity, in the form of confusing regulatory standards and enforcement, is negatively associated with corporate efforts in both basic and proactive environmental practices; yet, intensive inspections mitigate these negative associations with policy ambiguity.     

Multiphase flow simulation through porous media with explicitly resolved fractures

Accurate simulation of multiphase flow in fractured porous media remains a challenge. An important problem is the representation of the discontinuous or near discontinuous behaviour of saturation in real geological formations. In the classical continuum approach, a refined mesh is required at the interface between fracture and porous media to capture the steep gradients in saturation and saturation‐dependent transport properties. This dramatically increases the computational load when large numbers of fractures are present in the numerical model. A discontinuous finite element method is reported here to model flow in fractured porous media. The governing multiphase porous media flow equations are solved in the adaptive mesh computational fluid dynamics code IC‐FERST on unstructured meshes. The method is based on a mixed control volume – discontinuous finite element formulation. This is combined with the P_N+1DG‐P_NDG element pair, which has discontinuous (order N+1) representation for velocity and discontinuous (order N) representation for pressure. A number of test cases are used to evaluate the method's ability to model fracture flow. The first is used to verify the performance of the element pair on structured and unstructured meshes of different resolution. Multiphase flow is then modelled in a range of idealised and simple fracture patterns. Solutions with sharp saturation fronts and computational economy in terms of mesh size are illustrated.     

Latent trajectory models for space‐time analysis: An application in deciphering spatial panel data

This article introduces latent trajectory models (LTMs), an approach often employed in social sciences to handle longitudinal data, to the arena of GIScience, particularly space‐time analysis. Using the space‐time data collected at county level for the whole United States through webpage search on the keyword “climate change,” we show that LTMs, when combined with eigenvector filtering of spatial dependence in data, are very useful in unveiling temporal trends hidden in such data: the webpage‐data derived popularity measure for climate change has been increasing from December 2011 to March 2013, but the increase rate has been slowing down. In addition, LTMs help reveal potential mechanisms behind observed space‐time trajectories through linking the webpage‐data derived popularity measure about climate change to a set of socio‐demographic covariates. Our analysis shows that controlling for population density, greater drought exposure, higher percent of people who are 16 years old or above, and higher household income are positively predictive of the trajectory slopes. Higher percentages of Republicans and number of hot days in summer are negatively related to the trajectory slopes. Implications of these results are examined, concluding with consideration of the potential utility of LTMs in space‐time analysis and more generally in GIScience.
