Green Space Attachment and Health: A Comparative Study in Two Urban Neighborhoods

The positive relationships between urban green space and health have been well documented. Little is known, however, about the role of residents’ emotional attachment to local green spaces in these relationships, and how attachment to green spaces and health may be promoted by the availability of accessible and usable green spaces. The present research aimed to examine the links between self-reported health, attachment to green space, and the availability of accessible and usable green spaces. Data were collected via paper-mailed surveys in two neighborhoods (n = 223) of a medium-sized Dutch city in the Netherlands. These neighborhoods differ in the perceived and objectively measured accessibility and usability of green spaces, but are matched in the physically available amount of urban green space, as well as in demographic and socio-economic status, and housing conditions. Four dimensions of green space attachment were identified through confirmatory factor analysis: place dependence, affective attachment, place identity and social bonding. The results show greater attachment to local green space and better self-reported mental health in the neighborhood with higher availability of accessible and usable green spaces. The two neighborhoods did not differ, however, in physical and general health. Structural Equation Modelling confirmed the neighborhood differences in green space attachment and mental health, and also revealed a positive path from green space attachment to mental health. These findings convey the message that we should make green places, instead of green spaces.

Forced Displacement, Suffering and the Aesthetics of Loss

This article investigates how artists have addressed shocking experiences of displacement in different political contexts. Drawing on the notion of ‘the aesthetics of loss’ (Köstlin, 2010), it examines and compares the different aims, desires and strategies that have shaped the histories and social lives of paintings, memorial statues, installations and other artefacts. The analysis identifies a mode of artistic engagement with the sense of a ‘loss of homeland’ that has been commonly felt amongst Sudeten German expellees, namely the production and framing of visual images as markers of collective trauma. These aesthetics of loss are contrasted with the approach taken by the Dutch artist Sophie Ernst in her project entitled HOME. Working with displaced people from Pakistan, India, Palestine, Israel and Iraq, she created a mnemonic space to stimulate a more individualistic, exploratory engagement with the loss of home, which aimed, in part, to elicit interpersonal empathy. To simply oppose these two modes of aesthetic engagement, however, would ignore the ways in which artefacts are drawn into different discursive, affective and spatial formations. This article argues for the need to expose such dynamic processes of framing and reframing by focusing on the processual aspects of aestheticisation with attention to the perspective of loss.

Guerre et exil chez Louis-Ferdinand Céline

O nosso estudo incide, primordialmente, sobre as polémicas de carácter político e consequentes acusações de que Louis-Ferdinand Céline foi – e continua a ser – alvo. Tais aspectos conduzem-nos a questionar, com alguma veemência e perplexidade, as razões da sua fuga através da Alemanha, bem como as relações que estabeleceu com os Nazis durante a segunda guerra mundial. Num primeiro momento, elaborámos uma contextualização de cariz temporal e factual, tentando perceber – quiçá explicar -, o sentido das posições assumidas por Céline aquando da composição dos seus pamphlets, marcada por uma reivindicação violenta do seu antisemitismo e que surge, omnipresente, sob forma de cartas, entrevistas e outros escritos. Contudo, a essência do nosso trabalho consistiu numa análise detalhada das diferentes etapas dos anos de exílio do escritor, primeiro numa Alemanha devastada pela guerra, onde se refugia a partir de 17 de Junho de 1944 e mais tarde, na Dinamarca (1945-1951), de onde terá de responder às acusações de traição que lhe são dirigidas pela justiça francesa, antes de um regresso sem glória, a França, e de uma reabilitação tardia e titubeante. Os escritos que constituem o corpus do nosso trabalho traduzem, de modo inequívoco, a experiência amarga e cruel dos anos de exílio e da lembrança feita de dor e ódio, que o escritor sentiu profundamente, como um espinho na própria carne. Apesar do caminho tortuoso, que lhe confere uma aura de escritor “maldito”, Céline permanece, ainda hoje, como um dos maiores génios da literatura francesa do século XX.

Cross-readings and ecoliteracy in children's pop-up books

The purpose of this text is to analyse two recently been published pop-up books aimed at children, by Anouck Boisrobert e Louis Rigaud, Popville (2009) and Dans la forêt du paresseux [Wake up, Sloth!, En el bosque del perezoso] (first published in 2009 and 2012, accompanied with texts by Joy Sorman and Sophie Strady, respectively). These books were published originally in France by Hélium Editions, but they can now be found in several western countries and in many languages (Catalan, French, Dutch, English, German, Italian, Portuguese and Spanish, at least). The objective is to analyse their verbal text and their visual aspects produced by a sophisticated paper engineered to question how they achieve what seems to be one of their goals, the promotion of the readers' ecoliteracy (Orr, 1992) by his involvement in the reading process. This issue seems to be one of the main trends on children's literature in western societies nowadays, transcending the traditional and almost omnipresent role of scenario that nature plays in many children's narratives.

Electrical characterization of metal-oxide-polymer devices for non-volatile memory applications

The objective of this thesis is to study the properties of resistive switching effect based on bistable resistive memory which is fabricated in the form of Al2O3/polymer diodes and to contribute to the elucidation of resistive switching mechanisms. Resistive memories were characterized using a variety of electrical techniques, including current-voltage measurements, small-signal impedance, and electrical noise based techniques. All the measurements were carried out over a large temperature range. Fast voltage ramps were used to elucidate the dynamic response of the memory to rapid varying electric fields. The temperature dependence of the current provided insight into the role of trapped charges in resistive switching. The analysis of fast current fluctuations using electric noise techniques contributed to the elucidation of the kinetics involved in filament formation/rupture, the filament size and correspondent current capabilities. The results reported in this thesis provide insight into a number of issues namely: (i) The fundamental limitations on the speed of operation of a bi-layer resistive memory are the time and voltage dependences of the switch-on mechanism. (ii) The results explain the wide spread in switching times reported in the literature and the apparently anomalous behaviour of the high conductance state namely the disappearance of the negative differential resistance region at high voltage scan rates which is commonly attributed to a “dead time” phenomenon which had remained elusive since it was first reported in the ‘60s. (iii) Assuming that the current is filamentary, Comsol simulations were performed and used to explain the observed dynamic properties of the current-voltage characteristics. Furthermore, the simulations suggest that filaments can interact with each other. (iv) The current-voltage characteristics have been studied as a function of temperature. The findings indicate that creation and annihilation of filaments is controlled by filling and neutralizing traps localized at the oxide/polymer interface. (v) Resistive switching was also studied in small-molecule OLEDs. It was shown that the degradation that leads to a loss of light output during operation is caused by the presence of a resistive switching layer. A diagnostic tool that predicts premature failure of OLEDs was devised and proposed. Resistive switching is a property of oxides. These layers can grow in a number of devices including, organic light emitting diodes (OLEDs), spin-valve transistors and photovoltaic devices fabricated in different types of material. Under strong electric fields the oxides can undergo dielectric breakdown and become resistive switching layers. Resistive switching strongly modifies the charge injection causing a number of deleterious effects and eventually device failure. In this respect the findings in this thesis are relevant to understand reliability issues in devices across a very broad field.

First Annual Report of the Audubon Society of South Carolina

This document initially describes the rampant disregard for game laws in the state, which caused people to write to the Audubon Society to get involved. The responded by printing and distributing pamphlets with South Carolina’s game laws to educate citizens who were possibly violating the laws out of ignorance. The society appointed new wardens to enforce the gaming laws and a list of the new wardens is included in the document. There is a description of the work the wardens are supposed to do as well as their duty and pay. The society enlisted the government to help put a stop to the disregard for the games laws and the president wrote his opinion of their reactions to the problem. The document then includes a treasurer’s report and a list of members of the society. The document ends with the secretary’s report.

Purity of Blood and Caste. Identity Narratives among Early Modern Goan Elites

This essay analyses the roles played by purity of blood and caste in seventeenth-and eighteenth-century identity narratives of Goan clites. Goa and its population are usually excluded from the mainstream literature of Indian social history, and seldom related to the early-modern Atlantic world, making this case study all the more valuable as a place to think the topic of blood and caste. The early establishment and the longevity of the Portuguese imperial presence (1510-1961) in Goa, its location at the crossroads of multiple cultural geographies (Iberian and Indian, and later, also Dutch, British and French), as well as the systematic process of religious conversion of its inhabitants and the questions of legal equality that conversion entailed, all intensified the types, textures, layers and meanings of experiences of social differentiation in this colonial context. This mapping of the experiences of purity of blood and caste in early-modem Goa therefore illuminates from a new angle the role of European imperial powers in the mUltiple expressions of racial classification.
