Jasbir K. Puar,Terrorist Assemblages: Homonationalism in Queer Times

The importance of studying human–animal relationships and animal subjectivity is increasingly recognised by social and cultural geographers, particularly in agricultural pursuits. Little research, however, has been undertaken on animals in sport, resulting in a limited understanding of the perceptions and treatment of animals in society. To address this concern, we interrogate print media coverage of the construction and positioning of horses and humans in the controversial activity of jumps racing (National Hunt) in Australia between February 2008 and December 2009. We highlight the importance of seemingly contradictory human–animal relationships involving close frequent contact of some jumps racing advocates in contrast to the distanced, mediated relationships of jumps racing opponents. This paper highlights how the particular activity of jumps racing generates specific human–animal relationships and emphasises the need to reflect on the attitudes that shape and constrain human–animal relationships in varying contexts, including how these attitudes are mediated and the potential consequences for humans and other animals. These findings form the basis for a suggested research agenda that recognises the importance and articulation of proximity and mediation in human–animal relationships, particularly those focused on activities labelled ‘sport’.     

Swept under the rug: the problem of unacknowledged ambiguity in lithic residue identification

Microscopic analysis of organic residues on stone tools is used to interpret prehistoric stone tool functions. The morphology of some residues can be difficult to interpret, yet this ambiguity is rarely acknowledged in the literature. Our research seeks to understand the nature of this ambiguity by objectively identifying ambiguous residues in our reference collection. We trained four archaeologists in residue analysis using one part of our reference collection, then tested their ability to identify sixty-eight residues in another part of the same collection. Forty-eight of the residues in the test (70%) were correctly identified by three or all four subjects. We considered the remaining twenty residues, which were correctly identified by two or fewer of the subjects, to be ambiguous. These are most often in the hide-scraping, bone-scraping, and hardwood-scraping (macerated) categories, and tend to have an atypical morphology which falls in the range of variability of another residue category. Some of these residues also have optical properties which make them more difficult to image than others. We explore the potential for scanning electron microscopy (SEM) to improve residue identification in a second test. This test shows a modest improvement in identification success rates of ambiguous residues when SEM images are included. We conclude that while images from different types of microscopes can improve reliability of identification, some residues will always be ambiguous. Rather than being ignored, these ambiguities should be brought to light, closely examined, and published as such.     

Fields of gold: reflections on the research relations of the cultural policy researcher

ABSTRACT

This article discusses the methodological implications of the relations we have to our object of study as cultural policy researchers. We ask: What research relations we typically are part of and what social dimensions structure these relations? These questions are discussed by comparing field experiences from two cultural forms that can be characterized as polar opposites when it comes to the degree to which they are legitimized: contemporary opera and dance bands. We suggest that four dimensions are especially relevant to help ‘unpack’ the relations we typically find ourselves in as cultural policy researchers; cultural hierarchy, research conditions, geography and, gender and age. The coexistence of these dimensions means that the cultural policy researcher regularly finds him/herself in complex situations that we suggest should be analysed in terms of the ways in which, and the extent to which, we develop roles as insiders – or outsiders – in the field     

Characteristics of ionospheric irregularities capable of producing quasi-horizontal traces on ionograms

This paper presents simulated ionograms calculated for a parabolic ionospheric layer containing irregularities in the form of small amplitude waves. With small amplitudes, perturbation techniques can be used enabling results for the irregular ionospheres to be calculated from the results for smooth ionospheres. This approach is relatively straightforward and avoids having to ray trace new paths each time the irregularity parameters are changed. It is, however, restricted to irregularities which do not cause multiple echoes. Irregularities with vertical wavelengths of up to a few kilometres can produce significant changes in the ionosphere over height intervals smaller than those involved in reflecting a single pulse. Consequently, in the simulation procedure, it is essential to consider not just the carrier frequency but the complete frequency spectrum of the pulse. Irregularities with vertical wavelengths of the order of 10 km or more can produce ripples in an ionogram trace. These will, of course, be more evident on ionograms with high frequency resolution. Irregularities with vertical wavelengths of up to several kilometres and amplitudes up to a few per cent can produce significant pulse spreading and splitting. The actual effects depend not just on the irregularity properties but also on the ionosonde pulse width, gain and frequency and height resolutions. Some simulations show trace splitting and quasi-horizontal traces similar in many respects to effects observed by Bowman (1987, J. atmos. terr. Phys. 49, 1007) and Bowmanet al. (1988, J. atmos. terr. Phys. 50, 797). Consequently it is suggested that, at least in some cases, small amplitude (≤3%) and small scale (≤4 km) irregularities produce the spread-ifF reported by these authors.     

Pits and pitfalls: taxonomic variability and patterning in tooth mark dimensions

Archaeologists use experimentally derived tooth mark frequencies, locations, and size data to infer (a) the extent of carnivore involvement in the formation and modification of faunal assemblages, (b) the size classes of predators marking those assemblages, and (c) whether hominins accessed fleshy or defleshed carcasses (Blumenschine and Pobiner, 2007; Dominguez-Rodrigo et al., 2007). These inferences are often debated in part because frequency counts can vary widely among observers and because the carnivore taxa for which tooth mark dimensional data are available are limited. This study contributes to the body of actualistic/experimental tooth mark data and presents a methodology for collecting these data. We offer a greatly simplified method that may encourage others to collect and quantify tooth mark dimensions. We present dimensional data from feeding experiments with 16 omnivore and carnivore species of known age and mass, ranging in size from skunks to tigers, significantly expanding the taxonomic and size range of carnivores for which we have tooth pit data. Our results demonstrate considerable, but not complete, overlap in tooth pit dimensions among size, class, and taxon. Tooth mark dimensions on epiphyses and metaphyses were relatively strongly correlated with body mass, whereas diaphyseal tooth marks exhibited the weakest correlation. Human consumption of animal tissue produced tooth marks comparable in size to medium felids and small canids, suggesting the possibility that some tooth marks on Early Stone Age (ESA) faunal assemblages could, as suggested by Oliver (1994), result from small carnivore and/or hominin consumption.     

A note on the use of temporal frequency distributions in studies of prehistoric demography

Temporal frequency distributions of archaeological sites and radiocarbon dates are commonly used as proxies for prehistoric population levels based on the assumption that more people create a stronger archaeological signal. While this assumption is certainly correct, we question whether relative frequencies of sites or dates observed from prehistoric contexts are necessarily linked to human demography. In this paper, we demonstrate that the typical positive curvilinear frequency distributions observed in archaeological contexts also regularly occur in paleontological and geological contexts and are thus likely caused by the operation of time-dependent destructive processes, what we call “taphonomic bias.” Using a simple model, which assumes a constant rate of site loss over time, we show how taphonomic bias can produce positive curvilinear frequency distributions through time even in cases of population stasis, decline, and fluctuation. We conclude that caution must be used when attempting to infer demographic trends from frequency distributions alone.     

Crime and disorder, and house sales and prices around the casino sites in Windsor, Ontario, Canada

This study is an analysis of the impact of the opening or closure of a new urban casino on crime and disorder, and house sales and prices in its neighbourhood. The two sets of time-series data were the calls to the police about three types of offences and the house sales through the Multiple Listing Service in two neighbourhoods near the casinos in Windsor, Ontario, Canada. Temporally, the weekly numbers of offences and the mean monthly house prices were oscillating almost randomly around their respective declining or stationary long-term averages with no impulse from when a casino either opened or closed. Geographically, only two types of offences increased in number nearer to a casino site, but their respective distance decays neither moderated nor steepened after a casino had closed or opened. Even so, the conclusion is premature that the open or closed casinos have had benign effects on offences and house sales in the neighbourhoods.     

Large-scale irregularities of electron concentration in the southern magnetic anomaly area according to Intercosmos 19 satellite data

Using Intercosmos 19 satellite topside sounding data, a type of complex ionogram for which the lowest frequency of the radio-wave which has passed through the ionosphere is smaller than the greatest frequency of the radio-wave reflected from the ionosphere is considered. (Under normal conditions these frequencies are identically equal.) A mechanism is suggested by which radio-waves transmitted by the satellite propagate over 3000 km in the topside ionosphere in the presence of inclined large-scale plasma structures, which can explain the main features of such ionograms.The space-time distribution of this phenomenon on a global scale is analysed. It is shown that it manifests itself mainly in the local winter, in the daytime and in the Southern Hemisphere. It is hypothesized that these large-scale irregularities are formed in the vicinity of the South Atlantic magnetic anomaly and then move westward.     

Generation of gravity waves by inhomogeneous heating of the atmosphere

Local variation of atmospheric heating which might occur in inhomogeneities of various constituents such as ozone or molecular oxygen may generate gravity waves. These perturbations are induced by the terminator crossing constituent inhomogeneities of short lifetime. The quasi-point heating model developed here shows that the largest amplitude must appear vertically above the source, where the perturbation frequency is close to the Vaisala-Brunt frequency. Numerical calculations not band limited in the frequency suggest several characteristics of the perturbation.     

Spatial Empirics for Economic Growth and Convergence

This paper suggests some new empirical strategies for analyzing the evolution of regional income distributions over time and space. These approaches are based on extensions to the classical Markov transition matrices that allow for a more comprehensive analysis of the geographical dimensions of the transitional dynamics. This is achieved by integrating some recently developed local spatial statistics within a Markov framework. Insights to not only the frequency with which one economy may transition across different classes in the income distribution, but also how those transitions may or may not be spatially dependent are provided by these new measures. A number of indices are suggested as ways to characterize the space‐time dynamics and are illustrated in a case study of U. S. regional income dynamics over the 1929–1994 period.     

Skeletal Kinship Analysis Using Developmental Anomalies of the Foot

Developmental anomalies of the skeleton are often treated as mere curiosities, but in some contexts, they may prove useful to bioarchaeologists for answering questions about the past. One such use can be found in skeletal kinship analysis, where discrete traits can help to identify close genetic relatives in archaeological cemeteries. Previous research suggests that discrete traits used for skeletal kinship analysis should have several characteristics—they must obviously be heritable, but in addition, they should be easy to score as present or absent, their frequencies should not vary by age or sex, and they should be low frequency traits. Low frequency traits are less likely than higher frequency traits to be found in two individuals merely by chance. In this study, we consider 17 developmental anomalies of the human foot as candidates for use in skeletal kinship analysis. The traits are evaluated in terms of the characteristics described above, after which kinship analyses are attempted on two different populations. Ten of the anomalies are found to be good candidates for skeletal kinship analysis, including accessory navicular, four different forms of brachydactyly, three types of tarsal coalition, and two forms of the os intermetatarseum. When frequencies of these traits were examined and compared to a reference sample in three cemeteries, however, only a single group of six possible genetic relatives were identified. The results suggest that skeletal kinship analysis using individual heritable traits is perhaps best applied to small cemeteries or burial clusters rather than larger cemeteries containing many different lineages.

Spectral characteristics of high frequency waves backscattered by small scale F-region irregularities: evidence of strong sub-auroral ion flow

The spectra of high frequency waves backscattered at night by small scale (10–20 m) sub-auroral F-region irregularities often exhibit large Doppler shifts and widths in the local time sector 2000–2400. After local midnight the Doppler shifts and the widths of the spectra decrease rapidly. We present examples of experimental data, obtained with the two coherent backscatter radars of the EDIA¹ experiment, showing the spectral characteristics just mentioned. From the Doppler shift measured at the two sites we deduced the perpendicular velocity of the irregularities, which can reach values as high as 2000 ms ⁻¹. These observations are interpreted using results of theoretical models which predict strong sub-auroral ion flow in the trough region.     

Islands as interstitial encrypted geographies: Making (and failing) cryptosecessionist exits

Initiatives to build juridically autonomous cities based on libertarian and anarcho-capitalist ideals have proliferated in the last decade. These include seasteading, charter cities, and “free private cities.” These ventures are part of a movement to build so-called “start-up societies,” which proposes developing experimental, small-scale communities to explore alternatives to the nation-state. Many such projects have turned to islands and island-creation as an interstitial space in which their experiments could unfold and benefit from being located within, but juridically autonomous from, sovereign state territories. Such experiments are linked to and build on the earlier use of islands for plantations, military bases, special economic zones (SEZs) and offshoring. These ventures also often rely on, and are shaped by, blockchain and cryptocurrencies and create what Isabelle Simpson theorizes as “encrypted geographies.” In this article, we seek to better understand how islands are used to create encrypted geographies which in turn create alternative political economies and communities and how, conversely, the imaginary of islands, enclaves and archipelagoes shapes how these alternative territories are conceptualized. We examine several attempts to create such start-up societies in the Caribbean and the Pacific to consider where, how, and why their proponents have taken to islands to establish these new encrypted geographies. The concept of interstitiality can help us understand why islands are privileged sites for the creation of encrypted geographies, and how these are used to transcend state borders yet simultaneously create digitally bordered interstitial spaces that undermine sovereign territories and currencies, empower cyber-kinetic elites, and exclude and marginalize existing island communities, natural ecosystems, and existing oceanic and archipelagic polities, cultures, and societies.     

INTERPRETING SPATIAL ECONOMETRIC ORIGIN‐DESTINATION FLOW MODELS

Spatial interaction or gravity models have been used to model flows that take many forms, for example population migration, commodity flows, traffic flows, all of which reflect movements between origin and destination regions. We focus on how to interpret estimates from spatial autoregressive extensions to the conventional regression‐based gravity models that relax the assumption of independence between flows. These models proposed by LeSage and Pace ( 2008 , 2009 ) define spatial dependence involving flows between regions. We show how to calculate partial derivative expressions for these models that can be used to quantify these various types of effect that arise from changes in the characteristics/explanatory variables of the model.     

The theory of radio windows in the ionosphere and magnetosphere

Radio waves in a stratified plasma can sometimes penetrate through a region where, according to a simple ray theory, they would be evanescent. They emerge on the far side in a different magnetoionic mode. This occurs when the incident wave normal is within a small cone of angles, called a radio window. The best known example is the Ellis window, used to explain the Z-trace in ionosonde records. Other phenomena where windows may be important have recently been studied. Simple approximate formulae are given for the transmission coefficient of a window and for its angular widths. These show the dependence on frequency, electron concentration gradient and direction of the ambient magnetic field. Comparison with more accurate calculations shows that these formulae are likely to be reliable in practical applications. The tracing of rays near a window is discussed, and the properties of a second kind of window are described.     

Evidence of butchery and hominid activities at Torralba and Ambrona; an evaluation using microscopic techniques

Torralba and Ambrona have been interpreted as butchery sites for many years, a contention recently challenged; natural death or carnivore activities are invoked as an alternative explanation. Scanning electron microscopy (SEM) of bone surface replicas distinguishes among hominid-produced cutmarks, carnivore tooth scratches, and other types of bone damage. A sample of 102 replicas, comprising the most likely cutmarks on a combined sample of roughly 3000 fossils from Torralba and Ambrona, were scanned to determine the major agent of damage. Microscopically verified cutmarks are present, but rare, occurring in less than 1% of the bones in the combined sample. Carnivore tooth scratches are comparably rare. In contrast, evidence of sedimentary abrasion, which obliterates the diagnostic features of cutmarks, is present on nearly every bone from Torralba and Ambrona. It remains unresolved whether cutmarks were initially more common on these bones and were subsequently obliterated by abrasion, or whether the incidence of cutmarks was always low. These data demonstrate clearly that hominids and carnivores each damaged some bones at Torralba and Ambrona, but the frequency of each type of mark is too low to confirm strongly the interpretation of these sites as either butchery or carnivore remains.     

A wave guide model of lightning currents

In this paper, a lightning channel is simulated by a vertical wire of finite length and of moderate electric conductivity. At low frequencies, such a wire behaves like a resonant wave guide cavity in which only discrete resonant wave modes can be generated. The theory of resonant waves in a wire of finite diameter is outlined and applied to the return stroke with electric contact to the earth and to intracloud K-strokes without electric contact to the earth. Two types of current wave forms exist: aperiodic waves of the Bruce-Golde type and damped oscillations. The configurations of the electric charge density and the electric current in the wire are presented for the various wave modes as functions of height and time. From the observations of lightning current and of sferic wave forms, it is apparent that the first mode dominates, and that both types of wave forms can be identified. From these wave forms, the channel parameters-length and diameter can be derived. For the higher order modes, the resonance model loses its validity and freely propagating waves are expected during the whole lightning flash. These waves contribute to the observed continuous spectrum. The skin effect becomes important increasing the effective resistance of the wire with frequency. Since these waves interfere destructively, they do not contribute significantly to an effective charge transport.
