DECONSTRUCTING THE MAP

This chapter explores the representation of place in Last Resort within the contexts of a broader discussion of the history of representation of spaces and places on British film (including social realism). It argues that Last Resort draws much of its representational power from the ways in which it employs the semiotic potential of Margate architecture to speak of the struggle of its central character, Tanya. The chapter also demonstrates that, even more than contemporary British films such as Fish Tank and Red Road, Last Resort effectively foregrounds the semiotic power of architecture. The chapter charts key debates concerning the ways in which British cinema has depicted British places and constructed representational spaces. Last Resort develops a sense of space that draws on the obvious tensions that exist between past and present readings of carnivalesque and brutalist architecture in particular, and what these shifting interpretations might suggest about the construction of identity.

1 Cartographic Imagery and Representations of Power

History, including contemporary history, is as much about time as it is about space, place, and territory. Not accidentally, historians have long used paper maps as their data (maps made at different time periods) and as a form of analysis (e.g., historical atlases, maps of historic battles, etc.). Maps have always been an incredibly succinct and visually powerful way to tell a story. On the one hand, therefore, turning to digital mapping technologies is continuous with this tradition. On the other hand, geospatial technologies created new ways of analyzing and representing by connecting digital maps to data behind the map. In this way, they open new opportunities and pose new challenges to historians and other humanities scholars who engage with place and space on the crest of “spatial turn” and digital revolution. Geographers working in the fields of critical cartography and critical GIS have addressed these opportunities and challenges in a number of ways. This chapter will address some of these challenges and opportunities in relation to historical and contemporary mapping practices that contribute significantly to digital place-making, and include but are not limited to the web-based and neogeographical representations of place. In particular, how can digital place-making be understood in the context of such issues as maps as a medium of power, ontological power of maps and digital representations of place, authorship of maps, what gets to be represented and what is silenced, and what kind of information is conveyed and which is excluded? What are the implications of digital divide for digital place-making and online citizenship? I will examine the above questions drawing on a combination of critical social theory, feminism, post-structuralism, and postcolonial thought.

The development of geospatial artificial intelligence (GeoAI) systems depends on the ability to learn effective representations of places. To learn accurate place representations from spatial interactions, it is important to extract features that capture both the spatial and non-spatial driving factors. However, existing methods lack a robust interpretation and the explanatory power of the learned representations on spatial factors remains unexplored. Here, we propose an approach to learning place representations from spatial interactions. Our method is inspired by flow allocation, which is the main focus of single-constrained gravity models. We first validate the method on synthetic flows with known driving factors and then apply it to multi-scale real-world flows. Results show that the learned representations can effectively capture features that explain place characteristics, along with the impact of spatial impedance. Our study not only contributes an efficient method to learn place representations from spatial interactions but also offers insights into pre-training procedures in GeoAI.

Power and Cartographic Representations

This chapter presents a detailed introduction of the deities in the Middle East. The first deity is called Zeus-Jupiter represented in an epigraphical and archaeological manner. The religious figure of the Zeus-Jupiter is regular outcome of the Greco-Roman interpretation of Baal Hadad. The second deity is called Dionysus/Dusares whose figure is no longer to be demonstrated in the Middle East and elsewhere. The third deity is called Nemesis seen as the mirror of the society of the living. The popularity of the Nemesis to the Roman era is undeniable. Written or sculptured representations of imperial power s' often based on an analogy with the divine figures in order to divert their eternal essence, which appears to be an old game of traditional and authoritarian rule. The original text of the chapter is in French.Keywords: Dionysus/Dusares; imperial power; Middle East; Nemesis; Zeus-Jupiter

We propose the concept of Action-Related Place (ARPlace) as a powerful and flexible representation of task-related place in the context of mobile manipulation. ARPlace represents robot base locations not as a single position, but rather as a collection of positions, each with an associated probability that the manipulation action will succeed when located there. ARPlaces are generated using a predictive model that is acquired through experience-based learning, and take into account the uncertainty the robot has about its own location and the location of the object to be manipulated. When executing the task, rather than choosing one specific goal position based only on the initial knowledge about the task context, the robot instantiates an ARPlace, and bases its decisions on this ARPlace, which is updated as new information about the task becomes available. To show the advantages of this least-commitment approach, we present a transformational planner that reasons about ARPlaces in order to optimize symbolic plans. Our empirical evaluation demonstrates that using ARPlaces leads to more robust and efficient mobile manipulation in the face of state estimation uncertainty on our simulated robot.

Many researchers have suggested that cursorial mammals concentrate limb muscle mass proximally to reduce energy costs during locomotion. Although supported by experiments where mass is added to an individual's limbs, mammals with naturally occurring distally heavy limbs such as primates have similar energy costs compared with other mammals. This study presents a new hypothesis to explain how animals with distally heavy limbs maintain low energy costs. Since distal mass should increase energy costs due to higher amounts of muscular power outputs, this hypothesis is based on the divergent effects of stride frequency on internal and external power outputs (the power output to move the limbs and the body center of mass, respectively). The use of low stride frequencies reduces limb velocities and therefore decreases internal power, while associated long strides increase the vertical displacement of the body center of mass and therefore increase external power. Total power (the sum of internal and external power) may therefore not differ among mammals with different limb mass distributions. To test this hypothesis, I examined a sample of infant baboons (Papio cynocephalus) during ontogeny and compared them with more cursorial mammals. Limb mass distribution changes with age (from distal to more proximally concentrated) in baboons, and the infants used shorter strides and higher stride frequencies when limb mass was most proximally concentrated. Compared with non-primates who have more proximally concentrated limb mass, the infants used longer strides and lower stride frequencies. Relatively low internal power was associated with low stride frequencies in both the intra- and inter-specific samples. However, only in the inter-specific comparison were relatively long strides associated with high external power outputs. In both the intra-specific and the inter-specific samples, total power did not differ between groups who differed in limb mass distribution. The results of this study suggest that a trade-off mechanism is available to quadrupeds with distally heavy limbs allowing them to maintain similar total power outputs (and likely similar energy costs) compared with mammals with more proximally concentrated limb mass.

The internationally ‘famed’ Anti-Homosexuality Bill (AHB) represents an interesting and peculiar case through which to understand and unpack national political events, evolution within the ruling party and emerging power dynamics in Uganda. Amongst several coexisting interpretative discourses that explain the recent emergence of sexuality within politics in the country, this article provides an examination of the Museveni administration, the National Resistance Movement (NRM) and the political developments in relation to anti-gay feelings and the AHB. In fact, through a systematic and chronological analysis of events, discourses, public statements, newspaper articles and academic literature, the article reflects on the specific role that sexuality plays in the shaping activities of the NRM and its public representation and internal power dynamics. In doing so, the article identifies certain consistent themes and discursive frames concerning homosexuality that have emerged within the NRM and brings to light existing internal tensions as President Museveni attempts to hold onto power for yet another election in 2016.

The literature has unreasonably debilitated resource dependence theory’s explanatory power by haphazardly omitting external relations when exploring subsidiary decision-making and MNC power dynamics, myopically considering subsidiary power as having solely an MNC-internal component. The result is researchers exposing themselves to a fragmentary understanding of what truly drives subsidiary decision-making with respect to its knowledge development and, by extension, to its external embeddedness. In this conceptual paper we present a novel model that parses subsidiary power into internal and external power, and conceives it in terms of utility. We argue that the subsidiary’s total utility is a function of internal power (vis-à-vis the sister subunits) and external power (vis-à-vis local actors), therefore it aims to maximize its total power. However, since access to external network resources reduce the subsidiary’s inherent uncertainty from dependence on HQ resources, it increasingly places greater importance and focus on power dynamics in external relationships. As such, the subsidiary sacrifices internal power for external power, a welcome tradeoff it can leverage as bargaining power (vis-à-vis the HQ). By contrast, to increase its utility, the HQ seeks to decrease its own bargaining power.

At present, the black-start mode of the large power grid is mostly limited to relying on the black-start power supply inside the system, or only to the recovery mode that regards the transmission power of tie lines between systems as the black-start power supply. The starting power supply involved in the situation of the large power outage is incomplete and it is difficult to give full play to the respective advantages of internal and external power sources. In this paper, a method of coordinated black-start of large power grid internal and external power sources is proposed by combining the two modes. Firstly, the black-start capability evaluation system is built to screen out the internal black-start power supply, and the external black-start power supply is determined by analyzing the connection relationship between the systems. Then, based on the specific implementation principles, the black-start power supply coordination strategy is formulated by using the Dijkstra shortest path algorithm. Based on the condensation idea, the black-start zoning and path optimization method applicable to this strategy is proposed. Finally, the black-start security verification and corresponding control measures are adopted to obtain a scheme of black-start cooperation between internal and external power sources in the large power grid. The above method is applied in a real large power grid and compared with the conventional restoration strategy to verify the feasibility and efficiency of this method.

Abstract. Cartographers have been representing places and scenes for thousands of years. We know that there is not one single way to represent place. We can use a reference map, thematic map (not to mention all the different types), large scale, small scale, oblique and overhead remotely sensed image, hand-drawn cartoon maps, street view photographs, animated maps, and digital maps. We also know that the methods and then the resulting representations can be differentiated cartographically using established criteria. But, are these methods all equally effective in conveying a sense of place?We measure “effectiveness” by comparing activation differences in the parahippocampal place area when viewing different representations of place. The parahippocampal place area (PPA) is a region in the human brain that allows humans to recognize and characterize a place (or a representation of it) (Weiner et al., in press). The PPA is a functionally, as opposed to an anatomically, defined region. It overlaps several anatomical regions, including the parahippocampal cortex, the lingual gyrus, the collateral sulcus, and the fusiform gyrus (Figure 1) (Epstein, 2014). The place recognition function of the PPA has been well-documented (Weiner et al., in press; Epstein 2014, 2008; Baldassano et al. 2013; Aguirre et al., 1998; Epstein and Kanwisher, 1998), and we now know that this region is what allows humans to differentiate between a place and other objects such as faces, chairs, or apples.In this study, we measured the effect of cartographic representation on the human brain’s recognition of “place” by comparing the activation differences in the PPA. We compared four types of place representation: a street-view photograph of an urban environment, a drawn schematic similar to a subway-style map, a Google Maps street map, and a Google Maps satellite view. (Figure 2). The Google Maps images were used because they are common cartographic representations, and thus are likely representative of a general “map” condition.

Identifying loads that maximize mechanical power is important because training at such loads may optimize gains in dynamic athletic performance. The purpose of this study was to examine correlations between measures of external mechanical power output and internal mechanical joint power output across different loads during a weightlifting exercise. Ten subjects performed 3 sets of the clean exercise at 65, 75, and 85% of 1 repetition maximum (1RM). Peak external mechanical power output was calculated with 4 commonly used methods, whereas an inverse dynamics approach was used to calculate peak internal mechanical power output for the hip, knee, and ankle joints along with the peak of the sum of all internal joint powers. All peak mechanical power outputs were expressed as relative peak power by either ratio (watts per kilogram) or allometrically scaling to body mass (W·kg). Correlation coefficients were used to compare power output measures. The greatest numbers of significant correlations between internal and external power outputs were observed at 85% of 1RM, at this load hip and knee joint power outputs were correlated to external mechanical power output when calculated with the traditional work-energy method. In addition, the peak sum of all mechanical joint powers was correlated to mechanical power output when calculated with the impulse-momentum method at loads of 75 and 85% of the 1RM. Allometric scaling of power outputs yielded one more significant correlation than did the ratio scaled power outputs. These findings support the use of the work-energy method when making inferences about internal joint powers from external power outputs when loads equal to 85% of 1RM are being lifted. In addition, the impulse-momentum method may be used to make inferences about the sum of all internal joint powers from external power outputs when loads between 75 and 85% of 1RM are being lifted.

Controversies exist regarding quantification of internal power (IP) generated by the muscles to overcome energy changes of moving body segments when external power (EP) is performed. The aim was to 1) use a kinematic model for estimation of IP during knee extension, 2) validate the model by independent calculation of IP from metabolic variables (IP(met)), and 3) analyze the relationship between total power (TP = EP + IP) and physiological responses. IP increased in a curvilinear manner (5, 7, 13, 21, and 34 W) with contraction rate (45, 60, 75, 90, and 105 contractions/min), but it was independent of EP. Correspondingly, IP(met) was 5, 7, 10, 19, and 28 W, supporting the kinematic model. Heart rate, pulmonary oxygen uptake, and leg blood flow plotted vs. TP fell on the same line independent of contraction rate, and muscular mechanical efficiency as well as delta efficiency remained remarkably constant across contraction rates. It is concluded that the novel metabolic validation of the kinematic model supports the model assumptions, and physiological responses proved to be closely related to TP, supporting the legitimacy of IP estimates.

As far back as Thucydides, scholars have hypothesized that power affects the onset of conflict. Despite its importance, power remains a difficult concept to measure, and scholars have primarily relied on material measures that quantify the internal resources available to a state. This concentration on internal sources of power, however, excludes an important power resource available to a state: its external relations. It is reasonable to expect that when a state estimates the power of a potential opponent it looks not only at the internal resources but also at the power of states that would likely join the conflict. In this article, we develop a new measure of external power that explicitly accounts for the external sources of state power. Unlike previous studies that aggregate a state’s expected alliance contributions, our measure is based on the expected contribution of all states, allies and non-allies alike. We conduct a preliminary test of this new measure on dispute onset, and our results provide support for power preponderance over balance of power theories. External power parity contributes to dispute onset rather than deterrence. In addition, we show that examining the combined, rather than individual, effects of external and internal power produces some intriguing results, suggesting that one state’s internal power preponderance can be offset by another state’s preponderance of external power. These results altogether suggest that further studies examining the role of external power can produce fruitful results.
