New age constraints for hominid footprints found on Jeju Island,South Korea

In 2004 numerous hominid footprints, along with diverse animal footprints, were found in the Late Quaternary strata of Jeju Island, South Korea. However, the age of the sediments in which the footprints were found is still controversial. Previous age estimates included radiocarbon ages of ca. 15,000 yr BP (Late Pleistocene) and quartz optically stimulated luminescence ages of ca. 7000 yr BP (mid-Holocene). In this study we report on 11 AMS ¹⁴C dating results from a new set of samples collected from the footprint-bearing strata and from associated sediments. Despite some variations and age reversal, all samples collected from the footprint-bearing strata yielded ¹⁴C ages of late Pleistocene. These ages are comparable with previous radiocarbon dating results. Furthermore, the presence of the proboscidean footprints attributable to woolly mammoths in the footprint-bearing strata supports the radiocarbon dating results. Based on the new radiocarbon dates and the presence of the alleged mammoth footprints, the age of the hominid footprints found at Jeju Island is thought to be late Pleistocene (about 19,000–25,000 cal yr BP). Therefore, this is the second discovery of hominid footprints dated to the Pleistocene age in Asia, and the first to be discovered in Korea.     

Generating Confusion,Concern, and Precarity through the Right to Rent Scheme in Scotland

The Immigration Act 2016 has heralded an era of amplified Government intervention into day‐to‐day life, placing increased responsibility for border protection on UK citizens. Using interviews with representatives from the field of housing in Scotland, this paper examines one specific aspect of the Immigration Act 2016, the Right to Rent scheme. We investigate how the Right to Rent creates a precarious environment for all those who may appear to be non‐UK citizens. We argue that it may endorse senses of fantasy citizenship to inculcate people into acting on behalf of the state and is a driver for further division in society. Scotland provides a particularly interesting case study, as housing is a devolved power, but immigration is not. This creates an additional layer of tension in our interview data, as housing organisations are faced with a set of conditions imposed from Westminster, infringing on a field that Scotland has self‐determined for some time. Our interviews illustrate the level of confusion around the scheme, the fact that it is increasing criminalisation in the housing sector, and stresses that the scheme is offloading state responsibility for border protection.     

Project-based community participatory action research using geographic information technologies

The paper investigates the effects of a project-based community participation course in which students chose research topics relevant to a local community. Specifically, the students undertook the following projects: (1) creating a virtual 3D model of a local government office, (2) creating interactive digitized versions of mountain trails using geotourism, (3) determining optimal locations for trash recycling bins using network analysis, and (4) assessing the water quality of a local river. Geographic information technologies, such as GIS and Google Earth, were employed as analytical and visualization tools. The answers to a questionnaire, course evaluations, reflective journals, and interviews found that participants positively evaluated their learning experiences. In addition, the projects received favorable reviews from community members and professional geographers.     

Seismic Hazard Analysis Using Discrete Faults in Northwestern Pakistan: Part II – Results of Seismic Hazard Analysis

This article is the second of two companion articles that evaluate seismic hazard in northwestern (NW) Pakistan. Using the properties and characteristics of discrete faults in NW Pakistan described in the first article, probabilistic and deterministic seismic hazard analyses for 11 major cities in NW Pakistan were conducted. The results from both probabilistic and deterministic seismic hazard analyses exhibit good agreement. Median deterministic spectra compare favorably with uniform hazard spectra (UHS) for 475- or 975-year return periods, while the 84^th-percentile deterministic spectra compare favorably with the UHS for a 2475-year return period. Peak ground accelerations (PGAs) for 2475-year return periods exceed 1.0 g for the cities of Kaghan and Muzaffarabad, which are surrounded by major faults. The PGAs for a 475-year return period for these cities are approximately 0.6g — 3 to 4 times greater than estimates by previous studies using diffuse areal source zones. The PGAs for some cities located farther from faults (including Astor, Malakand, Mangla, Peshawar, and Talagang) are similar to those predicted using diffuse areal source zones. Seismic hazard maps for PGA and spectral accelerations at periods of 0.2 s and 1.0 s corresponding to three return period (2475, 975, and 475 years) were produced. Based on deaggregation results, a discussion of the conditional mean spectra for engineering applications is presented.     

The cultural industry policies of the Korean government and the Korean Wave

The paper examines how the Korean government promoted Korea’s cultural industries over the last 20?years. In the early 1990s, there was a radical departure in the government’s cultural industry policy, from that of political control over the cultural industries to viewing them as central to the government’s export-focused economic development strategies. The policy of developing the cultural industries was implemented in conjunction with government investment in other strategic industries, such as the information and communication technology industries. In the 2000s, the domestic market for cultural products expanded and diversified rapidly as the Korean society enjoyed improved living standards and a growing middle class demanded improved quality from Korea’s cultural products. The rapid development of other industries also facilitated the enhanced competitiveness of Korean cultural products in global markets. As a result, Korea’s cultural industries made substantial inroads into East-Asian markets in the late 1990s and into global markets in the 2000s.     

p‐Functional Clusters Location Problem for Detecting Spatial Clusters with Covering Approach

Regionalization or districting problems commonly require each individual spatial unit to participate exclusively in a single region or district. Although this assumption is appropriate for some regionalization problems, it is less realistic for delineating functional clusters, such as metropolitan areas and trade areas where a region does not necessarily have exclusive coverage with other regions. This paper develops a spatial optimization model for detecting functional spatial clusters, named the p‐functional clusters location problem (p‐FCLP), which has been developed based on the Covering Location Problem. By relaxing the complete and exhaustive assignment requirement, a functional cluster is delineated with the selective spatial units that have substantial spatial interaction. This model is demonstrated with applications for a functional regionalization problem using three journey‐to‐work flow datasets: (1) among the 46 counties in South Carolina, (2) the counties in the East North Central division of the US Census, and (3) all counties in the US. The computational efficiency of p‐FCLP is compared with other regionalization problems. The computational results show that detecting functional spatial clusters with contiguity constraints effectively solves problems with optimality in a mixed integer programming (MIP) approach, suggesting the ability to solve large instance applications of regionalization problems.     

Coercion and Warfare in the Rise of State Societies in Southern Zambezia

Researchers have raised a wide range of variables to account for the emergence and governance of complex polities. Warfare and investment in military power, along with an expansionist ideology, are often raised as catalysts for the emergence of state societies and hierarchical forms of leadership. In southern Africa’s Zambezian region, complex polities arose during the Later Iron Age, presently dated to the early second millennium CE. Wealth accumulation in the form of arable land for grazing cattle, as well as the development of a highly regulated elite ideology coupled with favorable climatic conditions, factored into this trajectory of sociopolitical development. This paper explores the role coercion may have played in cultural changes associated with increased political complexity in Zambezia. Coercive and persuasive leadership is often challenging to recognize archaeologically. Do we have sufficient visible datasets to support coercive power and conflict as a dominant factor for cultural change in this region? Was conflict a significant driver of change in the prehistoric Shashi-Limpopo Basin? How does the evidence stand up to scrutiny when evaluated against known archaeological signatures for warfare?
