Identifying the Impacts of Land-Use Spatial Patterns on Street-Network Accessibility Using Geospatial Methods

While the land use-street network nexus is well acknowledged, evidence for the one-way impacts of land-use patterns on street accessibility is still inadequate. The measurements of land-use patterns and street accessibility lack systematic knowledge. Their empirical correlations also lack geographical variability, constraining site-specific land-use practices. Therefore, this study overcame the aforementioned limitations by examining the two-level spatial models to formulate accessibility-oriented land plans, using a well-developed Chinese city as an example. Firstly, two landscape metrics—Euclidean Nearest-Neighbor Distance (ENN) and Similarity Index (SIMI)—were used to quantify the intra- and inter-land-use configurations, respectively. Both city-level and local accessibility were measured using spatial design network analysis. Performing both ordinary least squares (OLS) and geographically weighted regression (GWR) models, results identified the statistically significant effects of inter-land-use patterns on two-level street accessibility. An exception was that land-use configurations within residential and industrial regions were irrelevant to street accessibility. We also found GWR was a better-fitting model than OLS when estimating locally-varied accessibility, suggesting hierarchical multiscale land-use planning. Overall, locally heterogeneous evidence in this study can substantialize land use-street network interactions and support the decision-making and implementation of place-specific accessibility-oriented land use.     

Breaking the Silence: Mexican Children and Women's Confrontation of Bracero Family Separation, 1942–64

On 6 August 1942, the Mexican and US governments’ recruitment of Mexican men into the temporary contract labour programme known as the Bracero Program initiated a process that would deteriorate Mexican children and women's personal wellbeing and relationships to each other. The Bracero Program left children to endure the absence of their bracero fathers, while married women and caretakers transitioned into single motherhood under conditions and terms that drove an uncalculated number of these women into undocumented migration to the United States. Separation from their mothers further devastated children. The silence concerning the programme and the whereabouts and intentions of their immigrant parents alienated children from the mothers and caretakers left to care for them. Hence, mothers, caretakers and teachers came together to listen and talk to their children and each other about the dangerous realities of the programme in order to overcome the alienating silence driving them apart within the borders of Mexico. Using archival sources and the oral life‐histories of fifty Mexican children and women who endured the programme's separation of their families in San Martin de Hidalgo, Jalisco, Mexico, I argue that the anxiety and loss of Mexican children and women inspired mothers, caretakers and teachers to transition into instilling a gendered and transnational understanding of the dangers of the programme to their children and among themselves to prevent the onset of permanent alienation from each other.     

Canary islands aborigin sex determination based on mandible parameters contrasted by amelogenin analysis

Sex determination using mandible parameters is population dependent. In order to assess which measurements better characterize sex in prehispanic individuals from the Canary Islands, we blindly contrasted the results obtained by visual inspection and osteometric measurements with those obtained by molecular sexing using amelogenin ancient DNA analysis on teeth from the same material. Unambiguous sex classification was achieved by amplification of sex specific amelogenin alleles in 56 out of 76 mandibles (73.78% of the cases). Visual inspection led to a correct diagnosis in 66.04% of cases, with a greater proportion of errors for female (54.17%) than male (17.24%) mandibles. Osteometric measurements were able to assign sex correctly in 72.2% in the best of cases (mandibular height), a proportion similar to that obtained using a discriminant function (71.2%). By logistic regression analysis, ramus breadth, index ramus breadth/ramus height and mandibular length were the parameters independently related with a mistaken diagnosis of female sex, whereas bigonial width, ramus height and mandibular length were the parameters more closely and independently related to a mistaken diagnosis of male sex. In conclusion, diagnosis based on visual examination of the mandible or on its metric measurement only serves to roughly estimate sex with an accuracy of around 70% or less, at least among the prehispanic population from Gran Canaria. Amplification of amelogenin alleles leads to unambiguous identification of male and female alleles in 73.68% of cases, at least among the prehispanic population from Gran Canaria.     

Memory and Non-Place: Visual Testimonies of Japanese American Internment During World War II

This article addresses the little-known history of Japanese Latin American internment during WWII. Classified as ‘illegal aliens’ and ‘enemy aliens’, 2,264 Japanese Latin Americans were stripped of citizenship from their home countries, denied rights in the United States, and ultimately deprived reconciliation due to their undocumented status. Using the traces of this history as a case study, I explore the strategic memories Japanese Latin Americans create about non-place – spaces of statelessness or states of exception – that allow them to make claims about state violence committed against them under these conditions, and, second, argue that demands for justice against political violence entail not only bringing light to erased histories but also developing engaged acts of reception that account for survivors’ claims to the memories of non-place. Visual testimonies, such as the Denshō Digital Archive and the short documentary Hidden Internment: The Art Shibayama Story (2004), affectively connect a viewer/listener to the memory of trauma, to an inexpressible haunting, and thus are critical platforms for creating a collective memory between survivors and the digital generation of postmemory.     

Sharks in the lagoon? Fishing exploitation at the Neolithic site of Suwayh 1 (Ash Sharqiyah region,Arabian Sea,Sultanate of Oman)

The study of the fish bones from the Neolithic shell midden of Suwayh 1, excavated in the 2000s, identified a total of 1060 identifiable fish bones, from 23 families, 33 genera and 28 different species. Radiocarbon dating demonstrates that the sites date to the early 6th to mid 5th millennium BC. The results follow an eight-phase chronology highlighted by an earlier malacological study. The most important taxa were the Carcharhinidae (requiem shark), Rhinopteridae (cownose rays), Sparoidea (Sparidae and Lethrinidae: sea breams and emperors) and Ariidae (sea catfishes). The results of the fish study show that the Suwayh lagoon must have gradually opened up to the sea and been populated with mangroves. The unique presence of so many sharks at this site seems to indicate that the inhabitants had a special interest in shark fishing and that their location was ideal for this specialised activity. Two types of fishing nets and hooks have been discovered, which require the use of different fishing techniques.     

What makes people stay in or leave shrinking cities? An empirical study from Portugal

The attractiveness of cities as places to live determines population movements into or out of them. Understanding the appealing features is fundamental to local governments, particularly for cities facing population decline. Pull and push attributes can include economic aspects, the availability of amenities and psychological constructs, initiating a discussion around which factors are more relevant for migration. However, such discussion has been underexplored in studies of shrinking cities. In the present study, we contribute to the discussion by identifying pull and push factors in Portuguese shrinking cities. Data were collected using a face-to-face questionnaire of 701 residents in four shrinking cities: Oporto, Barreiro, Peso da Régua and Moura. Factor analysis and automatic linear modelling were used to analyse the data. Our results show that the economic activity is the most relevant feature for retaining residents. However, characteristics specific to each city, related to heritage and natural beauty, are also shown to influence a city’s attractiveness. The cause of population shrinkage was also found to influence residents’ assessments of the pull and push attributes of each city. Furthermore, the results show the relevance of social ties and of place attachment to inhabitants’ intention to continue living in their city of residence.     

The Evolution of Population Distribution on the Iberian Peninsula: A Transnational Approach (1877–2001)

Abstract

Surpassing the national perspective usually adopted, the authors confirmed the existence of a pattern of population distribution common to the whole Iberian Peninsula in the long run. This pattern is clearly associated with geographical factors. These variables seem to have more weight in explaining changes between 1877/78 and 1940 than in the period from 1940 to 2001. The observation of the cross-border region has shown that proximity to the frontier has not generated any distinct pattern of population density on either side of the boundary line. The spatial coherence of the observed phenomena throughout the Peninsula and of its evolution, independent of the border between states, reinforces the importance of geographic factors in their explanation. At the same time, this verification opens up new issues related to the effect of national political and economic policies.     

Muscles,Nerves, and Sex: The Contradictions of the Medical Approach to Female Bodies in Movement in France, 1847–1914

From the early nineteenth century in France, the treatment of hysteria was connected to both physical and moral development. As a result, therapeutic treatments envisaged by medical practitioners were influenced by and related to the formulation of precepts of medical gymnastics. This article considers how ‘physical education’ for women became part of medical discourse, specifically the elaboration of ‘body treatment’ as a remedy against nervous disorders including hysteria. From the Second Republic (1848) to the years of the belle epoque (1914), the discourse concerning the medical cause of ‘hysterical madness’ is marked by the progressive discrediting of reflections that located the causes of pathology in the genitals. However, the shaping of a neuro‐cerebral etiology did not fully replace discussions of the relationship between hysteria, female bodies and the uterus. While the current historiography emphasises the participation of doctors in the production and legitimation of physical exercises in the nineteenth century, some aspects of this process are not yet fully explored. We examine the ambivalences of medical discourse, between the rhetoric of the eternally wounded woman and the need to develop women's abilities (intellectual, moral, and physical) to ensure healthy children. And despite the shadows that still obscure the etiology of nervous disorders, there is, in our period, a genuine dynamic favouring experimental therapeutics. The ‘movement disorders’, such as chorea, hysteria or neurasthenia, were handled by increasingly well‐established regimes utilising physical exercise. The introduction of gymnastics in the hospital played a fundamental role in this process; it enabled experimentation and lent legitimacy to physical exercise as therapy.     

Elasmosaurs (Sauropterygia,Plesiosauria) from the La Colonia Formation (Campanian–Maastrichtian), Argentina

O’Gorman, J.P., Salgado, L., Varela, J., & Parras, A., 2013. Elasmosaurs (Sauropterygia, Plesiosauria) from the La Colonia Formation (Campanian–Maastrichtian), Argentina. Alcheringa 37, 257–265. ISSN 0311-5518.

Elasmosaur postcranial remains from the La Colonia Formation (Campanian–Maastrichtian), Chubut Province, Patagonia, Argentina, are described. The new material has small dimensions and caudal vertebrae with parapophyses strongly projected laterally—characters shared with some Elasmosauridae indet. from the coeval Allen Formation, Río Negro Province, Argentina. These features reinforce the similarities between the plesiosaur faunas to the north and south of the Somún Curá Plateau. The small size of these elasmosaurs may be palaeoecologically related to the marginal marine depositional environment of the sedimentary host rocks.
