ABSTRACT When European colonists arrived in the late 19th century, large villages dotted the coastline of the Gulf of Papua (southern Papua New Guinea). These central places sustained long-distance exchange and decade-spanning ceremonial cycles. Besides ethnohistoric records, little is known of the villages’ antiquity, spatiality, or development. Here we combine oral traditional and 14C chronological evidence to investigate the spatial history of two ancestral village sites in Orokolo Bay: Popo and Mirimua Mapoe. A Bayesian model composed of 35 14C assays from seven excavations, alongside the oral traditional accounts, demonstrates that people lived at Popo from 765–575 cal BP until 220–40 cal BP, at which time they moved southwards to Mirimua Mapoe. The village of Popo spanned ca. 34 ha and was composed of various estates, each occupied by a different tribe. Through time, the inhabitants of Popo transformed (e.g., expanded, contracted, and shifted) the village to manage social and ceremonial priorities, long-distance exchange opportunities and changing marine environments. Ours is a crucial case study of how oral traditional ways of understanding the past interrelate with the information generated by Bayesian 14C analyses. We conclude by reflecting on the limitations, strengths, and uncertainties inherent to these forms of chronological knowledge.

This paper presents the results of a study on cross-linguistic transfer in Andean Spanish word order. In Andean Spanish the object appears in preverbal position more frequently than in non-Andean Spanish, which has been attributed to an influence from Quechua (a Subject–Object–Verb language). The high frequency of preverbal objects could be explained by focus fronting. The main syntactic properties of focus fronting in Spanish are weak crossover and long distance movement. Two elicitation studies designed to test for these properties in non-Andean Spanish, Andean Spanish and Quechua show no evidence of syntactic transfer from Quechua into Andean Spanish. Rather, the analysis of naturalistic data and an elicitation study on question–answer pairs show that there is pragmatic transfer from Quechua into Andean Spanish. The study has implications for theories of syntax and language contact, and especially for the debate on the nature of cross-linguistic transfer.

The electric bicycle is considered as an environmentally friendly mode, the market share of which is growing fast worldwide. Even in metropolitan areas which have a well-developed public transportation system, the usage of electric bicycles continues to grow. Compared with bicycles, the power transferred from the battery enables users to ride faster and have long-distance trips. However, research on electric bicycle travel behavior is inadequate. This paper proposes a cumulative prospect theory (CPT) framework to describe electric bicycle users’ mode choice behavior. Different from the long-standing use of utility theory, CPT considers travelers’ inconsistent risk attitudes. Six socioeconomic characteristics are chosen to discriminate conservative and adventurous electric bicycle users. Then, a CPT model is established which includes two parts: travel time and travel cost. We calculate the comprehensive cumulative prospect value (CPV) for four transportation modes (electric bicycle, bus, subway and private car) to predict electric bicycle users’ mode choice preference under different travel distance ranges. The model is further validated via survey data.

Healthy Growth

Rapid growth of sharing economy in the last two decades is the outcome of a paradigm shift in global capitalism and societal values. Based on digital identity and the Trust and Reputation Index, IT platforms have brought together strangers who under new social construct, share under-utilized capacities and assets with those who need them. Radius of trust which was initially confined to family and friends; now encompasses strangers who speak no common language and who live oceans apart. Hungary is no exception to this global shift. Sharing economy in Hungary has registered healthy growth specially in the areas of transportation and accommodation. Oszkár, a long-distance car-sharing company presents a good example of this paradigm shift in societal values and sharing with strangers. This platform has recorded impressive growth of over 67% between 2015-2018 with very positive customer reviews. Moreover, this represents an environmentally-friendly sustainable practice which successfully reduces carbon foot-print and traffic congestion.

Illustrative Application

Chapter 6’s illustrative application of the theory demonstrates how the propositions are instructive when critically applied a Taiwan war scenario. In this case, it demonstrates how spacepower can influence terrestrial considerations for battle, in particular with long-distance precision-strike warfare, or ‘anti-access/area denial’ (A2/AD) warfare in current military jargon. Two contrasting strategies are critiqued in the case study as equally valid possibilities – the all-out first strike ‘Space Pearl Harbor’ strategy and ‘Counterspace-in-Being’ strategy of keeping space strikes in reserve for a critical moment. These strategies are two possible options for both the United States of America and People’s Republic of China, with Taiwan also having many opportunities of its own to resist Chinese invasion from the mainland. Projecting support from celestial communications down to Earth from the cosmic coastline changes the calculations of concentration and dispersal for military forces on Earth, and understanding the thorny questions of how and when to strike against space systems is aided by an understanding of all seven propositions.

The Individual

Wearable technologies' popularity in sporting practices continues to grow. Runners use GPS watches and activity trackers to track steps, log miles, map courses, and monitor heart rates. Likewise, wearables are integrated into long distance running events, with race officials relying on technologies to effectively execute events. However, technologies can also enable and monitor cheating. Many studies focusing on the individual explore why cheaters make unethical decisions. Actor-Network Theory shifts cheating's focus from the individual and moral failings to an assemblage that includes not only the runner, but nonhumans, such as technology, as well. A 2015 Canadian Ironman cheating incident case study illuminates intricate relationships and networks between humans and nonhumans. By examining the intersections of cheating and technology in running sports, the authors see where and how technology works as intended or is repurposed. Whereas a human-centered approach to sport and cheating dismisses wearables' agency, Actor-Network Theory reveals their underexamined, sociotechnical complexities.

Jobs–housing imbalance is a hot topic in urban study and has obtained many results. However, little research has overcome the limits of administrative boundaries in job accessibility measurement and considered differences in job accessibility within multiple commuting circles. Using Baidu location data, this research proposes a new method to measure job accessibility within multiple commuting circles at the grids’ level. Taking the Wuhan metropolitan area as a case study, the results are as follows: (1) Housing and service jobs are concentrated in the central urban areas along the Yangtze River, whereas industrial jobs are scattered throughout suburbs with double centers. The potential competition for job opportunities is fiercer in the city center than in the suburbs. (2) Job accessibility with different levels shows significant circle-like distribution. People with long- or short-distance potential commutes demand to live close to the groups with the same demand. Residents with long-distance commutes demand to live outside of where those with short-distance commutes demand to reside, regardless of whether their commuting demand is for service or industrial jobs. (3) There are three optimization patterns for transit services to increase job accessibility in various areas. These patterns involve areas with inadequate job opportunities, poor transit services to service jobs, and poor transit services to industrial jobs. Developing current transit facilities or new transit alternatives as well as adding extra jobs near housing could improve jobs–housing imbalance in these areas. Findings from this study could guide the allocation of jobs and housing as well as the development of transport to reduce residents’ commuting burdens and promote transportation equity. The method used in this study can be applied to evaluate jobs–housing imbalance from the perspective of the supply in other metropolises.
