The K‐Function Method on a Network and Its Computational Implementation

This paper proposes two statistical methods, called the network K‐function method and the network cross K‐function method, for analyzing the distribution of points on a network. First, by extending the ordinary K‐function method defined on a homogeneous infinite plane with the Euclidean distance, the paper formulates the K‐function method and the cross K‐function method on a finite irregular network with the shortest‐path distance. Second, the paper shows advantages of the network K‐function methods, such as that the network K‐function methods can deal with spatial point processes on a street network in a small district, and that they can exactly take the boundary effect into account. Third, the paper develops the computational implementation of the network K‐functions, and shows that the computational order of the K‐function method is O(n²_Q log n_Q) and that of the network cross K‐function is O(n_Q log U3Q), where n_Q is the number of nodes of a network.     

Geographic information system‐based edge effect correction for Ripley's K‐function under irregular boundaries

Ripley's K‐function is a test to detect geographically distributed patterns occurring across spatial scales. Initially, it assumed infinitely continuous planar space, but in reality, any geographic distribution occurs in a bounded region. Hence, the edge problem must be solved in the application of Ripley's K‐function. Traditionally, three basic edge correction methods were designed for regular study plots because of simplified geometric computation: the Ripley circumference, buffer zone, and toroidal methods. For an irregular‐shaped study region, a geographic information system (GIS) is needed to support geometric calculation of complex shapes. The Ripley circumference method was originally implemented by Haase and has been modified into a Python program in a GIS environment via Monte Carlo simulation (hereafter, the Ripley–Haase and Ripley–GIS methods). The results show that in terms of the statistical powers of clustering detection for irregular boundaries, the Ripley–GIS method is the most stable, followed by the buffer zone, toroidal, and Ripley–Haase methods. After edge effects of irregular boundaries have been eliminated, Ripley's K‐function is used to estimate the degree of spatial clustering of cities in a given territory, and in this paper, we demonstrate that by reference to the relationship between urban spatial structure and economic growth in China.     

A Procedure to Generate Thiessen Polygons

An algorithm to generate Thiessen diagrams for a set of n points defined in the plane is presented. First, existing proximal polygon computation procedures are reviewed and terms are defined. The algorithm developed here uses a rectangular window within which the Thiessen diagram is defined. The computation of Thiessen polygons uses an iterative walking process whereby the processing starts at the lower left corner of the diagram and proceeds toward the right top corner. The use of a sorted point sequence and dynamical core allocation provide for efficient processing. The presentation is concluded by the discussion of an implementation of the algorithm in a FORTRAN program.     

A Statistical Method for Analyzing the Spatial Relationship between the Distribution of Activity Points and the Distribution of Activity Continuously Distributed over a Region

This paper shows a statistical method for analyzing the spatial relationship between the distributions of two different kinds of activity in a region. One kind of activity is discretely distributed as points in a region (such as the distribution of retail stores), and the other kind of activity is continuously distributed over the region (such as the distribution of population). First, three models representing the relationship between the above two distributions are formulated. Second, statistical methods for fitting these models to data are developed and the measures of fitness are proposed. Third, using these measures, the relationship between the distributions of thirty-seven kinds of retail stores and the distribution of population is examined in a suburb of Osaka in Japan.     

Why Are Clovis Fluted Points More Resilient than Non‐Fluted Lanceolate Points? A Quantitative Assessment of Breakage Patterns Between Experimental Models

For decades, archaeologists have wondered whether the Clovis Palaeoindian (c.11 600–10 800 radiocarbon years bp ) practice of ‘fluting’, a flake removal technique that creates a distinctive shallow channel extending from the base of the projectile point towards the tip, bestowed a functional advantage over non‐fluted projectile points. Using analytical modelling and static engineering experiments, Thomas et al. (2017) found that points that more effectively redistribute stress and relocate damage can absorb significantly more energy, last longer and remain intact relative to points that do not experience these phenomena. In general, stress redistribution and damage relocation is significantly more likely to occur in fluted points, as opposed to non‐fluted points, suggesting that fluting acts as a ‘shock absorber’. Here, we present a comparative quantitative assessment of breakage patterns between Thomas et al.’s (2017) experimental points that shows those experiencing stress redistribution and damage relocation were also able to significantly better resist breakage, and to incur non‐catastrophic breaks, than points that less effectively redistribute stress and relocate damage. This more beneficial breakage pattern explains the material advantages provided by stress redistribution and damage relocation, and hence the potential motivation for fluting. This does not preclude the possibility that the process of fluting was accorded significance beyond its possible utilitarian value. Additional tests will be necessary to further resolve the ‘shock‐absorbing’ capabilities of fluting.     

Seasonality and age structure in an archaeological assemblage of Sika deer (Cervus nippon)

Sika deer (Cervus nippon) was one of the major terrestrial mammals hunted in Japan throughout the Jomon period, which extends from the end of the Palaeolithic until the arrival of rice agriculture in the first millennium bc . Mandibular analysis of hunted deer is believed to be more useful in determining the season of death than antlers in archaeological contexts. This paper aims to present a new method of estimating an occupational season of a Jomon site by using sika deer mandibles. This method consists of two stages. First, two measurements on a mandible should be taken. If the distribution shows any gaps among young juveniles, this strongly suggests that the sika was hunted in a specific season. Second, tooth eruption and attrition stage should be observed; this may suggest the season in which hunting took place. This method was utilized to analyse sika deer remains from Awashimadai in eastern Kanto. The result of the analysis shows that deer were hunted only from spring to summer at Awashimadai. Putting these results together with the estimate of seasonality deduced from other species strongly suggests that the site was occupied only from April to July. This paper also examines how the tooth attrition stages of sika deer progress. The preliminary comparison with red deer (Cervus elaphus) in England suggests that molar wear progresses more quickly in sika than in red deer. Copyright © 1999 John Wiley & Sons, Ltd.     

Redundancy as an Index of Change in Point Pattern Analysis

Point pattern analysis based on concepts from information theory can go beyond existing techniques. Direct measurement of spatial form is achieved when Thiessen polygons are constructed around the points; in this scheme, each point's proportion of total area may be treated like a probability. Three information-theoretic indices are available for analysis of a distribution of such probabilities. Entropy is density dependent. Redundancy, defined as the difference between observed and maximum entropy, seems to avoid this problem when the number of individuals in a pattern exceeds twenty. Comparisons of prior and posterior redundancy provide an indication of change in overall pattern form. An information gain expectation reflects changes for each individual in a pattern. Here, point-area redundancy parameters are determined for Poisson-generated patterns, using a gamma distribution of polygon areas and a computer-generated set. An application to an urban crime problem illustrates the use of these parameters in the analysis of pattern change.     

Analysis of a Distribution of Point Events Using the Network‐Based Quadrat Method

This study proposes a new quadrat method that can be applied to the study of point distributions in a network space. While the conventional planar quadrat method remains one of the most fundamental spatial analytical methods on a two‐dimensional plane, its quadrats are usually identified by regular, square grids. However, assuming that they are observed along a network, points in a single quadrat are not necessarily close to each other in terms of their network distance. Using planar quadrats in such cases may distort the representation of the distribution pattern of points on a network. The network‐based units used in this article, on the other hand, consist of subsets of the actual network, providing more accurate aggregation of the data points along the network. The performance of the network‐based quadrat method is compared with that of the conventional quadrat method through a case study on a point distribution on a network. The χ² statistic and Moran's I statistic of the two quadrat types indicate that (1) the conventional planar quadrat method tends to overestimate the overall degree of dispersion and (2) the network‐based quadrat method derives a more accurate estimate on the local similarity. The article also performs sensitivity analysis on network and planar quadrats across different scales and with different spatial arrangements, in which the abovementioned statistical tendencies are also confirmed.     

Eine verklungene Novelle Zur Deutung des PSI 725

This paper treats a rhetorical fragment which is preserved in Stobaeus from four points of view. (1) The speech was delivered in Alexandria by a travelling rhetor. (2) There is a philosophical background with a Cynic flavour to this oration, which advocates concord within the city. (3) An analysis of the literary form shows that this text can be regarded as an example of a λαλι?. (4) The date has been very much debated, but a study of the vocabulary makes a date in the second half of the second century A.D. seem plausible.     

Shellfishing and the Colonization of Sahul: A Multivariate Model Evaluating the Dynamic Effects of Prey Utility,Transport Considerations and Life-History on Foraging Patterns and Midden Composition

ABSTRACT

Archaeological evidence of shellfish exploitation along the coast of Sahul (Pleistocene Australia-New Guinea) points to an apparent paradox. While the continental record as a whole suggests that human populations were very low from initial colonization through early Holocene, coastal and peri-coastal sites dating to that time are dominated by small, low-ranked, littoral taxa to the near-complete exclusion of large, higher ranked, sub-littoral species, precisely the opposite of theory-based expectations, if human populations and predation rates were indeed as low as other data suggest. We present a model of shellfish exploitation combining information on species utility, transport considerations, and prey life-history that might account for this apparent mismatch, and then assess it with ethnographic and archaeological data. Findings suggest either that high-ranked taxa were uncommon along the Pleistocene coastlines of Sahul, or that abundant and commonly taken high-ranked prey are under-represented in middens relative to their role in human diets largely as a function of human processing and transport practices. If the latter reading is correct, archaeological evidence of early shellfishing may be mainly the product of subsistence activities by children and their mothers.     

Increasing Unevenness in the Distribution of City Sizes in Post-Soviet Russia

This paper describes the distribution of urban areas in post-Soviet Russia using the rank-size method for quantifying longitudinal change. As many studies show, urbanization under state socialism achieved a relatively uniform city-size distribution in accordance to Marxist ideals. I test the initial hypothesis that variation in city size would increase after dissolution of the USSR, to converge toward distributions found in market economies. The analysis shows that increasing unevenness in city-size depends on the nature of variation that existed prior to the USSR's disintegration, as well as on geographic location within Russia.

An Empirical Comparison of Edge Effect Correction Methods Applied to K‐function Analysis

This paper explores various edge correction methods for K‐function analysis via Monte Carlo simulation. The correction methods discussed here are Ripley's circumference correction, a toroidal correction, and a guard area correction. First, simulation envelopes for a random point pattern are constructed for each edge correction method. Then statistical powers of these envelopes are analyzed in terms of the probability of detecting clustering and regularity in simulated clustering/regularity patterns. In addition to the K‐function, K(h), determined for individual distances, h, an overall statistic k is also examined. A major finding of this paper is that the K‐function method adjusted by either the Ripley or toroidal edge correction method is more powerful than what is not adjusted or adjusted by the guard area method. Another is that the overall statistic k outperforms the individual K(h) across almost the entire range of potential distances h.     

DISTINCT,LATE BRONZE AGE (c. 1650 bc) WALL‐PAINTINGS FROM AKROTIRI,THERA, COMPRISING ADVANCED GEOMETRICAL PATTERNS*

This paper studies a set of wall‐paintings of the Late Bronze Age (c. 1650 bc ) initially decorating the internal walls of the third floor of the edifice called ‘Xeste 3’, excavated at Akrotiri, Thera, whose restoration is now in progress. It deals with the methods used for the drawing of the geometrical figures appearing in these wall‐paintings. It is demonstrated that most of the depicted configurations correspond with accuracy to geometrical prototypes such as linear spirals and canonical polygons. It is pointed out that the steady lines of the figures, their remarkable repeatability, the precision of the geometrical shapes and their even distribution in the wall‐paintings indicate a very distinctive use of the ‘Xeste 3’ third floor, which is now investigated.     

Lulik: Taboo,Animism, or Transgressive Sacred? An Exploration of Identity,Morality, and Power in Timor‐Leste

This article explores the continued significance of lulik for people living in the central highlands of Timor‐Leste today, lulik being a term frequently translated as ‘sacred’. In contrast to the straightforward definition of lulik as the sacred property of religious places or objects set apart from everyday life, it shows that lulik is understood as a potency that animates the environment and that is concentrated in specific sites in the landscape, in ancestral objects and houses. As a vital energy that sustains life, yet that is connected to prohibitions, danger, and restrictions, lulik shares an affinity with similar phenomena found in Melanesia, Polynesia, and Southeast Asia (such as mana, tapu, or semangat). Engaging with recently reinvigorated approaches to animism and Durkheim's notion of the sacred, this article examines how lulik that emerges when distinctions between human and non‐human entities are collapsed. The analysis of how Funar residents maintain a distance from this transgressive force leads to an exploration of how lulik is connected to the constitution of the self, and how lulik is mobilized as a source of power and morality.     

Do ‘in vitro children’ exist? The ‘ontological choreography’ between public debates and private experiences in Poland

ABSTRACT

Children who were born used IVF in Poland are subject of vivid discussion nowadays. In this article, we probe the ontology of the in vitro child: do in vitro children exist? If so, how and where? We analyse how an ‘IVF child’ is constructed through public discourses and private narratives. We explore media publications, as well as doctors’ and parents’ narratives concerning IVF children. A very strong voice in the debate has Catholic Church, which opposes medically assisted reproduction. Our main interest in this text are the answers of children and adults born using in vitro. Even young children recognize some focal points from the debate over assisted reproduction and refer to them. Their narratives show that they feel interpellated into existence by various discourses. In this manner, we argue, being an ‘in vitro child’ in Poland is a political status, not a biological one.     

Superstitionis Malleus: John Toland,Cicero, and the War on Priestcraft in Early Enlightenment England

Summary

This paper explores the role of the Ciceronian tradition in the radical religious discourse of John Toland (1670–1722). Toland produced numerous works seeking to challenge the authority of the clergy, condemning their ‘priestcraft’ as a significant threat to the integrity of the Commonwealth. Throughout these anticlerical writings, Toland repeatedly invoked Cicero as an enemy to superstition and as a religious sceptic, particularly citing the theological dialogues De Natura Deorum and De Divinatione. This paper argues that Toland adapted the Ciceronian tradition so that it could function as an active influence on the construction of his radical discourse. First, it shows that Toland championed a particular interpretation of Cicero's works which legitimised his use of Cicero in this rational context. Then, it shows the practical manifestations of this interpretation, examining the ramifications for how Toland formed three important facets of his campaign against priestcraft: his identification of priestcraft as a superstition; his argument for a rational religion in which priestcraft could play no role; and his portrayal of anticlericalism as a service to the Commonwealth.     

Auto-production systems in Japan: organisational and locational features

Through their highly controlled production systems Japanese auto-makers have succeeded to a considerable degree in extending the basic principles of modern factory production–specialisation and timing–to regional space. Thousands of firms, large and small, hierarchically connected in subcontracting layers supply a myriad of parts and engineering services to the auto-makers. Automakers minimise the level of stocks of parts at their plants by requiring their direct suppliers to make frequent deliveries. These firms function as extensions of the auto-maker's plant with the result that the regional production system functions with precision approaching that of a single well-organised factory.     

A new ‘bone-cracking’ dasyurid (marsupialia), from the Miocene of Riversleigh,northwestern Queensland

Ganbulanyi djadjinguli gen. et sp. nov. is described on the basis of an upper molar and premolar from an early-late Miocene site in Riversleigh, northwestern Queensland. The paucity of material constrains certainty in the determination of it's phylogenetic position. But, among dasyuromorphians, and dependent on the interpretation of tooth homology, this species shows unequivocal synapomorphies only with the derived dasyurine Sarcophilus, and/or Barinya wangala, a possible sister taxon to the modern dasyurid radiation (i.e., Sminthopsinae, Phascogalinae, Dasyurinae). Other apomorphies, evident in G. djadjinguli, are common to both carnivorous thylacinids and dasyurids within the order. Some dental features of Ganbulanyi djadjinguli are treated as adaptations to a ‘bone cracking’ habitus. If this interpretation is correct, then this species represents the only pre-Pliocene Australian taxon known to occupy such a niche and perhaps the smallest specialist ‘bone-cracker’ within Mammalia.     

Bluebeard's Female Helper: The Ambiguous Rôle of the Strange Old Woman in the Grimms' “Castle of Murder” and “The Robber Bridegroom”1

“Bluebeard” criticism has constantly overlooked the presence, in some versions, of an old woman in the forbidden chamber. The ambiguity of this figure, helper of both victim and villain, points to the way the story highlights the various roles women have to play in the patriarchal world of the Märchen. If there is a message in these stories, it is about the importance of female communication and bonding in a patriarchal world where isolation too often leads to a woman becoming a victim.
