Strategizing for Autonomy: Whither Durability and Progressiveness?

What should autonomous formations work towards? How might they strategize to get there? This paper considers these what and how aspects in tandem—a necessary pursuit if clearer pathways to emancipation are to be realized. First, it conceptualizes the relationship between objectives of durability and progressiveness. I introduce “the durability trap”, a situation whereby autonomous formations achieve durability at the expense of their progressiveness, as well as the principles to overcome this. Second, it evaluates how autonomous formations might act collectively and vis‐à‐vis the state to achieve, or not, both durability and progressiveness. I compare the strategies two autonomous formations adopt in response to the development of Media Spree, a redevelopment project in Berlin. I show how symbiotic strategy results in the durability trap and how an interstitial approach works to overcome this. I end by conceiving strategies of interstitiality, symbiosis and rupture as sequential steps to wider transformation.     

LEADERS,FOLLOWERS, AND ASYMMETRIC LOCAL TAX POLICY DIFFUSION

Complementing recent theoretical models of tax competition with endogenous leadership, we empirically model local policy diffusion as a dynamic asymmetric process. Using a setting where local option sales taxes rapidly transitioned from nonexistence to ubiquity, we construct a policy leadership index to classify jurisdictions as leaders or followers. Using models that control for vertical tax competition effects, we show how asymmetric leader–follower dynamics characterize horizontal tax competition over the three decades that follow. A placebo test further supports our main conclusions. This methodological approach could be adapted to other settings where policies exhibit both extensive and intensive margins.     

How not to build a world wireless network: German–British rivalry and visions of global communications in the early twentieth century

Abstract

Edward Snowden’s revelations laid bare an unprecedented scale of state influence on communications technology. But government elites have frequently shaped technological development through their beliefs about potentially nefarious uses of communications. This article argues that beliefs about how other states or groups might use a technology can shape innovation. In particular, German visions about the British use of cables spurred German investment in developing wireless telegraphy. Germans imagined that the British were using cable technology to damage Germany’s reputation, spy on Germany and ‘poison’ neutral countries against the Central Powers. The German government and military at first created a colonial wireless network to bypass British cables. In World War I, however, they sought to establish a world wireless network. In the end, innovation was significantly shaped by how Germans imagined their enemies’ uses of communications technology.     

Assessing the Scale and Pace of Large Shell-Bearing Site Occupation in the Prince Rupert Harbour Area,British Columbia

Methodological advancements in geoarchaeology and spatial and chronological modeling are opening new avenues to interpreting large coastal shell-bearing sites. We document the developmental histories of two such sites around Prince Rupert Harbour, Canada, using systematic percussion coring, intensive radiocarbon dating, and 3D surface mapping with Total Station and LiDAR. We also re-analyze a third site (Boardwalk/GbTo-31) excavated and radiocarbon dated in the 1960s, 1970s, and early 2000s using archival field notes, site maps, and stratigraphic profiles georectified using LiDAR. We map the natural landform beneath the sites and document the degree to which people physically modified landforms through the deposition of massive shell accumulations. We model site development through time and space and use accumulation rates and OxCal modeling to test for intentional deposition events. All three sites demonstrate complex and heterogeneous occupation histories. At each we identify instances of very rapid deposition that effectively terraced and extended parts of the natural landform to create places for constructing houses, though these episodes take place within longer histories of slower quotidian deposition. The anthropogenic modifications to the coastline in this area are the result of these mixed processes associated with long histories of occupation.     

Assessment of open spaces in inland medium-sized cities of eastern Andalusia (Spain) through complementary approaches: spatial-configurational analysis and decision support

The benefits of urban open spaces for improving the quality of life and sustainability in cities are widely recognized. The functions they perform within the framework established by urban planning, as well as their metrics, are now more complex than in the past. It is convenient to develop methodologies for the evaluation of these spaces adapted to the present time to check their level of efficiency, which is useful in urban planning for the establishment of new urban open spaces. The aim of this study is to classify such spaces through a methodology that integrates spatial analysis, configuration analysis, and decision support so as to understand their complexity from a more advanced analytical perspective. In order to do this, a prior exploration of specific literature is carried out, which allows the characterization of the functions of urban open spaces by means of the corresponding analysis variables in a weighted manner. The integrated combination of these advanced tools is a step forward in achieving consistent and detailed results for urban open spaces. They perform their functions best in dense, central, equipped, accessible, connected, and easily walkable urban environments. In addition, future recommendations are provided.     

Quantifying artefacts over time: Interval estimation of a Poisson distribution using the Jeffreys prior

This paper presents a new method for estimating the amount of an artefact class in use at a given moment in the past from a random assemblage of archaeological finds. The method is based on the use of simulation, since an analytical solution is computationally impractical. Estimating the number of artefacts in use at any time t is shown to follow a Poisson distribution, which allows for credible intervals to be established using the Jeffreys prior. This estimator works from minimal assumptions about the dating and duration of finds, as well as the intensity of collection, and is applied to coinage from four Roman‐period sites excavated by the Roman Peasant Project (2009–14). The result provides an estimation of the abundance of material according to an interval of certainty.     

Orientation of the Romanesque churches in the region of Val d’Aran,Spain (11th–13th centuries)

This study examines an ensemble of Romanesque churches in the region of Val d’Aran in the Spanish Pyrenees, built between the 11th and 13th centuries. Seven topographical studies performed between 2014 and 2015 examined these churches systematically using terrestrial laser scanning (TLS) as a data‐acquisition technique. The data obtained allowed for a geometrically accurate analysis of the orientation of these churches based on four Romanesque liturgies: Gemma animae (c.1120), by Honorius of Autun; Rationale divinorum officiorum (c.1150), by Jean Beleth; Mitralis de Officio (1190), by Sicard, Bishop of Cremona; and Prochiron, vulgo rationale divinorum officiorum (1291), by Guillaume Durand.     

NMR as a new tool for cultural heritage application: The provenance of ancient white marbles

Identifying the origin of marble used in antiquity brings back to light details of the economic, social and political organization of classical societies, and characterizing in depth the chemistry of marble is key to discovering its provenance. Beyond X‐ray diffraction, which could reveal the presence of discriminant secondary crystalline phases and the quantification of accessory minerals combined with a multivariate analysis approach, solid‐state nuclear magnetic resonance (NMR) enables one to recognize the local structure arrangement of both crystalline and amorphous materials by looking at one or more selected atoms. In present paper targets the ¹³C nuclide, and thus the major component of marble, calcium carbonate. Whatever their geological origin, marbles ¹³C‐NMR spectra present only one resonance corresponding to the carboxyl function whose intensity and line width vary from one marble to another. If the variation of the NMR signal intensity observed is the result of great T1 variations (from 220 to 5300 s) and is linked to iron content, the line width reflects defects in the calcite crystal in which calcium has been replaced by another element such as magnesium, aluminium or strontium. The specific profile of the NMR signal has been used successfully to help determine the origin of some archaeological items.
