This chapter deals with some technical aspects of the spatial strategy for overcoming the huge challenges posed by the pandemic. The focus of this chapter is to highlight the use of GIS tools and positioning technologies in diverse contexts to manage the threat of COVID-19. For this task, three stages of analysis are proposed. In a first preventive stage, some governments applied socioeconomic criteria drawn from existent statistical information to spatially identify the areas with a clear predisposition toward the accelerated spread of the contagion. In a second stage, when the pandemic fully reached a rapid pace of expansion and lockdown measures became necessary, the technologies helped to monitor the most affected areas and to establish a dashboard deployment for visualizing the severity of the catastrophe. In the third stage, after the establishment of control and mobility protocols, different governments resorted to mobile phone positioning as a resource for monitoring quarantine compliance and recognizing if social group behavior entailed any evident risk or spread.

Abstract This essay revisits the territoriality of the Qin empire by examining the spatial division underneath its commandery-county system. With the universal implementation of centralized administration, scholars usually believe that the Qin empire exerted strong control across its territories. But new Qin sources suggest otherwise. It is evident that the Qin regime devised multiple schemes to structure its empire into three concentric zones with asymmetrical political relations. The respective features and functions of these zones were consonant with those of the center, semiperiphery, and periphery in the “core-periphery” model. The regime’s spatial strategy can be understood as a compromise made to accommodate the diverse landscape in different parts of its vast empire, especially in the newly conquered regions. This reminds us that despite having installed the unitary commandery-county system, the territorial control wielded by the Qin regime in its new territories was tenuous at best.

Rapid market transition in post-reform China has created various socioeconomic spaces that fall beyond the Leninist mode of control by the Chinese Communist Party (CCP), and thus constitutes a formidable challenge to its ruling capacity.  This article examines the evolving adaptations of the CCP and the rise of a new form of Party-society nexus in urban China. We found that Party organisers have been fostering a spatial strategy in the context of ‘disorganised urban socialism’. By spanning institutional and sectoral gaps, engaging so-called ‘floating party members’, and developing community-based service networks, the Party has deliberately combined a specific social mechanism with the Leninist logic of organising. We conclude with a broader discussion of the possible scenario and political implication of CCP’s organisational consolidation from below.

In this article I examine a recent communal cocoa planting project in a Wide Bay Mengen community in East Pomio, Papua New Guinea in relation to histories of resource extraction. I discuss how the community members modeled the current planting of cocoa in accordance with earlier forms of agriculture, namely copra production and swidden horticulture. The cocoa planting project is linked to a longer history of labour and resource extraction in Pomio. I analyze the cycles of labour recruitment, logging, and oil palm expansion through the framework of the frontier, by which I mean a spatio-temporal process through which certain areas are portrayed as having abundant resources, which are made available for extraction. The cocoa planting project was a local response to these conditions and intended to be a source of income based on inalienated labour and local landholding and a spatial strategy of establishing points of access to other places, called 'doors' by the community members. My aim in this article is twofold. First, I argue that the frontier understood as a spatio-temporal process helps us to conceptualize cycles of resource extraction. Second, I show how people living in areas understood as frontiers form their own analyses and responses to the conditions under which their land, labour, and resources are made available to others. Keywords: cocoa, commodification, frontier, infrastructure, natural resources, oil palm, Papua New Guinea, place, territorialization

<p>“Oceania is vast, Oceania is expanding, Oceania is hospitable and generous, Oceania is humanity rising from the depths of brine and regions of fire deeper still, Oceania is us.”¹  ­‐ Epeli Hau’ofa  This research investigates how indigenous visual spatial strategies can be used to assist in the definition of a framework that helps characterise Oceanic perspectives and methods of creative practice. Cultural diversity in the New Zealand context holds important potential for explaining expressions of use and continuing the development of Oceanic creative practice. I will assert that the indigenous spatial strategy known as vā (space) holds important potential to help understand the significance of collective relationships within the Oceanic creative community. Vā is an indigenous spatial strategy that captures the process of engaging with and nurturing connections that, I argue, should be at the forefront of the definition for Oceanic creative practice. By comparing established Eurocentric understandings of creative disciplines and processes to indigenous understandings and methodologies, this research will posit indigenous spatial strategies as not only relevant but pivotal to 21st-century creative exploration and practice. This research will contribute to the outlining of a framework that helps to define the authentic values held within Oceanic creative practice.  ¹ Epeli Hau'ofa, "Our Sea of Islands," The Contemporary Pacific 6, no. 1 (1994): 160.</p>

Different strategies dependent on different brain regions may be spontaneously adopted to solve most spatial memory and navigation tasks. For this dissertation, I used brain-imaging and cognitive tasks to test the hypothesis that individuals living with schizophrenia spectrum disorders (SSD) have selective hippocampal-dependent spatial memory impairment. A hippocampal-dependent spatial strategy (locale/allocentric/cognitive map/viewpoint-independent) involves relying on learning the relations between landmarks in the environment, whereas a response strategy (taxon/egocentric/viewpoint-dependent) is more associated with caudate function and involves learning a sequence from a single starting position. In Experiment 1, I examined performance and brain activation with fMRI during the 4-on-8 virtual maze (4/8VM) to test the hypothesis of intact response versus impaired spatial memory in SSD. The SSD participants who adopted a spatial strategy performed more poorly and had less hippocampal activation than other groups. In Experiment 2, I further examined these data using multivariate PLS (partial least squares) analyses to identify whole-brain patterns of activation associated with group and strategy differences on the 4/8VM. Results revealed clusters of correlated activation within the temporal lobe unique to the SSD-Spatial group. The SSD Response group activated the same regions as the Healthy groups, but to a greater extent suggesting over-activation. In contrast to the between-subjects nature of strategy differences on the 4/8VM, for Experiment 3 I used the Courtyard Task to seek converging evidence of a selective hippocampal-dependent impairment in spatial memory using a within-subjects design. The Courtyard Task has previously demonstrated impaired performance among individuals with hippocampal lesions under shifted-view (allocentric) but not same-view (egocentric) conditions. Consistent with a profile of hippocampal dysfunction, the SSD group demonstrated a particular deficit under the shifted-view condition. The results support the development of protocols to train impaired hippocampal-dependent abilities and harness non-hippocampal dependent intact abilities. Overall, this dissertation provides valuable information characterizing spatial memory and highlights the importance of strategy use in SSD.

There is strong evidence that schizophrenia (SCZ) patients perform poorly on spatial memory tasks. We investigated whether these deficits were associated with subdivisions of spatial memory (locale/cognitive map and taxon/response) or whether these deficits represented a general cognitive decline. This study investigated the types of spontaneous navigation strategies used by individuals living with SCZ to solve the 4 on 8 task. It was predicted that SCZ participants who spontaneously chose a spatial strategy would have the longest latencies and make the most errors. Four of five measures of latency and errors produced a medium magnitude effect size (
