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.

Marcial e a "Epopeia do quotidiano" : a dimensão épica de um poeta

O século I, que desabrochou numa Idade de Ouro, não findaria sob o signo da boa Fortuna inaugurada pelo primeiro Princeps. O século de Augusto conheceria o seu fim! A Literatura não pôde furtar-se ao fatum de todo um Império e, depois de 69, juntamente com a Magna Vrbs, aguardava um tempo que fosse, finalmente, capaz de uma renovação. Para os anos oitenta do século I, prometiam os Flavianos e as suas consecuções uma nova Aurea Aetas… Porém, revelou-se impossível recuperar o passado: então, como nunca antes, os abastados demandavam a púrpura e a populaça clamava por panem et circenses. E a mudança definitiva dos tempos tinha na produção artística das suas maiores provas — a clientela condenara os autores ao abandono! Longe os círculos de Mecenas, apoiando Horácios e Virgílios que podiam abraçar em exclusivo a sua arte… Marcus Valerius Martialis foi não apenas um autor cuja existência se ressentiria dos constrangimentos que esta época reservou aos poetas, como o que faria da sua obra o mais fiel espelho do seu tempo. Aliás, não fora a sua obra e não se compreenderia cabalmente como foi possível a um escritor sobreviver a esses tempos e trazer à luz o seu trabalho — a uma luz muito especial, na verdade: Hic est quem legis ille, quem requiris, / toto notus in orbe Martialis (1.1.1-2)! Para cantar o novo Império e o seu quotidiano, onde conviviam, a um tempo, a grandeza e a torpeza, nada melhor que uma rude auena, jocosa e mordaz... O epigrama, não a epopeia, era a nova voz de Roma! E Marcial, elevando a sua auena, aplicou toda a sua mestria na celebração da sua Roma e dos Romanos seus concidadãos — hominem pagina nostra sapit (10.4.10). Teremos nós perdido um épico talentoso que se devotou e à sua arte a um género menor ou teremos ganho um cantor ímpar que viveu em perfeita harmonia com o seu tempo? Alcançando a imortalidade, reservada, antes, para os épicos, Marcial alcançou o seu objetivo: si […] / [...] fas est cineri me superesse meo (7.44.7- 8). E, no entanto, o feito singular de Marcial foi dar cumprimento às suas palavras — angusta cantare licet uidearis auena, / dum tua multorum uincat auena tubas. (8.3.21-22) —, escrevendo, sob a forma de epigramas, a primeira e, talvez, a única epopeia do quotidiano!

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.

Poetry With People With Dementia: An Evaluation of a Two Year Project Engaging in Poetry Activities With Older People in Residential and Nursing Homes.

This paper is a summary of an evaluation of the first two years of a three year poetry project for older people with dementia. The project was set up with a poet in residence who mentored six poets to deliver poetry activities to older people and those with dementia in residential and care homes in Herefordshire. The project was developed and run by the Courtyards Hereford. The evaluation was undertake through the use of questionnaires that were given to staff and carers undertaking training workshops and the poets, staff and carers in the homes who facilitated the activities and finally by the residents who took part in the project. The main findings were that participants that responded to the questionnaire for staff and carers it had increased confidence and assisted them in gaining more knowledge about the residents, whilst for residents it had a number of positive effects including enhanced communication, increased self-esteem and enhanced self-worth whilst making them feel less isolated.
