Lost in Transition? Emerging forms of residential architecture in Kathmandu

Kathmandu has been the last few cities in the world which retained its medieval urban culture up until twentieth century. Various Hindu and Buddhist religious practices shaped the arrangement of houses, roads and urban spaces giving the city a distinctive physical form, character and a unique oriental nativeness. In recent decades, the urban culture of the city has been changing with the forces of urbanisation and globalisation and the demand for new buildings and spaces. New residential design is increasingly dominated by distinctive patterns of Western suburban ideal comprising detached or semi-detached homes and high rise tower blocks. This architectural iconoclasm can be construed as a rather crude response to the indigenous spaces and builtform. The paper attempts to dismantle the current tension between traditional and contemporary 'culture' (and hence society) and housing (or builtform) in Kathmandu by engaging in a discussion that cuts across space, time and meaning of building. The paper concludes that residential architecture in Kathmandu today stands disoriented and lost in the transition.

Impact of age, various forms of cataract, and visual acuity on whole-field scotopic sensitivity screening for glaucoma in rural Taiwan.

OBJECTIVE: To evaluate the impact of age, various forms of cataract, and visual acuity on whole-field scotopic sensitivity screening for glaucoma in a rural population. DESIGN: Clinic-based study with population-based recruitment. SETTING: Jin Shan Township near Taipei, Taiwan. SUBJECTS: Three hundred forty-six residents (ages, > or = 40 years) of Jin Shan Township. INTERVENTIONS: Whole-field scotopic testing, ophthalmoscopy with dilation of the pupils, cataract grading against photographic standards, and screening visual field testing in a random one-third subsample. MAIN OUTCOME MEASURES: Whole-field scotopic sensitivity (in decibels) and diagnostic status as a case of glaucoma, glaucoma suspect, or normal. RESULTS: Participants in Jin Shan Township did not differ significantly in the rate of blindness, low visual acuity, or family history of glaucoma from a random sample of nonrespondents. Scotopic sensitivity testing detected 100% (6/6) of subjects with open-angle glaucoma at a specificity of 80.2%. The mean +/- SE scotopic sensitivity for six subjects with open-angle glaucoma (32.78 +/- 1.51 dB) differed significantly from that of 315 normal individuals (38.51 +/- 0.22 dB), when adjusted for age and visual acuity (P = .05, t test). With linear regression modeling, factors that correlated significantly with scotopic sensitivity were intraocular pressure, screening visual field, best corrected visual acuity, presence of cortical cataract, and increasing age. CONCLUSIONS: Although cataract affects the whole-field scotopic threshold, it appears that scotopic testing may be of value in field-based screening for glaucoma.

Palavras e imagens de mãos dadas: a arquitetura do álbum narrativo em Manuela Bacelar

É objetivo da presente investigação a análise sistemática do álbum narrativo infantil, mais concretamente, da obra escrita e ilustrada por Manuela Bacelar, numa leitura dialógica das suas componentes linguística e pictórica. Partindo de um conspecto teórico-crítico do conceito e da caracterização do álbum enquanto género maior da literatura, o estudo centra-se no exame técnicocompositivo do corpus, procurando indagar alguns dos traços e/ou dos recursos formais, retórico-estilísticos e ideotemáticos que singularizam a obra desta premiada artista plástica, assentando em algumas das modernas correntes literárias (e.g., a intertextualidade e a metaficção) que a inscrevem numa estética pós-modernista. As repercussões práticas do contacto precoce com o álbum e os seus contributos na promoção de comportamentos emergentes de literacia são analisados num estudo de caso que a investigação contempla. Analisando a interação entre as vertentes textual e icónica sublinha-se a especificidade de um género que aposta na narrativização como forma de aproximar a criança do universo plástico e literário.

Survey forms used in urban freight studies

Report produced as part of the Green Logistics project (EPSRC and Department for Transport funded). This report contains examples of survey forms used in urban freight studies both in the UK and overseas. The studies from which these examples have been drawn range in data from 1970-2008. The purpose of the report is to provide insight into the types of questions used in different survey techniques and also into the design of survey forms. It is hoped that bringing together in a single document these examples of urban freight survey forms will be of use to researchers involved in such studies in future in planning and designing their survey work. Examples of several different types of survey techniques are provided including: Establishment surveys -- Commodity flow surveys -- Freight operator surveys -- Roadside interview surveys -- Driver surveys -- Vehicle observation surveys -- Parking surveys -- Vehicle trip diaries -- Service provider surveys

The potential for neighbourhood regeneration in a period of austerity: changing forms of neighbourhood governance in two cities

Localism is an active political strategy, developed in a period of austerity by the UK's coalition government as a justification for the restructuring of state-civil society relationships. The deprived neighbourhood has long been a site for service delivery and a scale for intervention and action, giving rise to a variety of forms of neighbourhood governance. Prior international comparative research indicated convergence with the US given the rise of the self-help conjuncture and the decline of neighbourhood governance as a medium of regeneration. The subsequent shift in the UK paradigm from ‘big’ to ‘small state’ localism and deficit-reducing cuts to public expenditure confirm these trends, raising questions about the forms of neighbourhood governance currently being established, the role being played by local and central government, and the implications for neighbourhood regeneration. Two emerging forms of neighbourhood governance are examined in two urban local authorities and compared with prior forms examined in earlier research in the case study sites. The emerging forms differ significantly in their design and purpose, but as both are voluntary and receive no additional funding, better organised and more affluent communities are more likely to pursue their development. While it is still rather early to assess the capacity of these forms to promote neighbourhood regeneration, the potential in a period of austerity appears limited. Reduced funding for local services increases the imperative to self-help, while rights to local voice remain limited and the emerging forms provide little scope to influence (declining) local services and (still centralised) planning decisions, especially in neighbourhoods with regeneration needs which are likely to lack the requisite capacities, particularly stores of linking social capital. Initial conclusions suggest greater polarity and the further containment of deprived neighbourhoods.

Towards more sustainable urban forms in the city of Benghazi: a study of urban fragmentation at the neighbourhood level

Urban sprawl is a challenge to the sustainability of many cities around the world. Fragmented urban development and vacant land are widespread problems in many Arab cities (UN-Habitat, 2012) which are, according to Ben-Hamouch, mainly a result of inappropriate modern planning and poor land management (2013). This study addresses the problem of urban fragmentation at the neighbourhood level and examines to what extent the concept of compact urban form can contribute to the improvement of social and environmental sustainability in the Libyan city of Benghazi and Arab cities in general. The objectives and scope of the study have justified a morphological approach, where eleven case studies that present different urban typologies in the city have been investigated. The research strategy and selection of case studies were driven by the availability of data and meant to cover the main urban types and important issues defined within this context. This research, which has been conducted to explore and explain the relationships that exist between local urban forms and their performance in terms of sustainability, has produced valuable knowledge and helped to identify measures which target the improvement of people’s quality of life and environmental sustainability of the city. The research draws on the argument that adopting a type of human scale urban form, which is relatively compact and dense, well-connected and comfortably diverse, coupled with concepts of urban greening and flexible development relevant to the local context, would help to create a high quality urban form that is liveable and accessible, while causing minimum damage to the natural environment. This work is an attempt to respond and add to the ongoing debate on sustainable urban form in the developing countries (see: (Jenks, 2000)). The findings have contributed to the understanding of urban fragmentation and highlighted the relevance of the theory of compact city to sustainable development in Benghazi and the South in general. It is anticipated that this work would raise awareness on the impact of urban fragmentation on the sustainability of the built environment within this context and help to advance research on planning theory and practice based on real-life experience and responses to local circumstances.

Sensory imagery in individuals who are blind and sighted: examining unimodal and multimodal forms

Introduction: Previous research has suggested that visual images are more easily generated, more vivid and more memorable than other sensory modalities. This research examined whether or not imagery is experienced in similar ways by people with and without sight. Specifically, the imabeability of visual, auditory and tactile cue words was compared. The degree to which images were multimodal or unimodal was also examined. Method: Twelve participants totally blind from early infancy and 12 sighted participants generated images in response to 53 sensory and non sensory words, rating imageability and the sensory modality, and describing images. From these 53 items, 4 subgroups of words, which stimulated images that were predominantly visual, tactile, auditory and low-imagery, respectively, were created. Results: T-tests comparing imageability ratings from blind and sighted participants found no differences for auditory and tactile words (both p>.1). Nevertheless, whilst participants without sight found auditory and tactile images equally imageable, sighted participants found images in response to tactile cue words harder to generate than visual cue words (mean difference: -0.51, p=.025). Participants with sight were also more likely to develop multisensory images than were participants without sight (both U≥15.0, N1=12, N2=12, p≤.008). Discussion: For both the blind and sighted, auditory and tactile images were rich and varied and similar language was used. Sighted participants were more likely to generate multimodal images. This was particularly the case for tactile words. Nevertheless, cue words that resulted in multisensory images were not necessarily rated as more imageable. The discussion considers whether or not multimodal imagery represent a method of compensating for impoverished unimodal imagery. Implications for Practitioners: Imagery is important not only as a mnemonic in memory rehabilitation, but also everyday uses for things such as autobiographical memory. This research emphasises both the importance of not only auditory and tactile sensory imagery, but also spatial imagery for people without sight.

Conversions of Relief: on the perception of depth in drawings

Of the many ways in which depth can be intimated in drawings, perspective has undoubtedly been one of the most frequently examined. But there is also an equally rich history associated with other forms of pictorial representation. Alternatives to perspective became particularly significant in the early twentieth century as artists and architects, intent on throwing off the conventions of their predecessors, looked to new ways of depicting depth. In architecture, this tendency was exemplified by Modernism’s preference for parallel projection – most notably axonometric and oblique. The use of these techniques gave architects the opportunity to convey a new and uniquely modern form of spatial expression. At once shallow and yet expansive, a key feature of these drawings was their ability to support perceptual ambiguity. This paper will consider the philosophy and science of vision, out of which these preoccupations emerged. In this context, the nineteenth-century discovery of stereopsis and the invention of the stereoscope will be used to illustrate the way in which attempts to test the limits of spatial perception led to an opening up of visual experience; and provided a definition of visual experience that could encompass the representational ambiguities later exploited by the early twentieth-century avant-garde.

Development of electrochemical methods for determination of tramadol - analytical application to pharmaceutical dosage forms

A square-wave voltammetric (SWV) method and a flow injection analysis system with amperometric detection were developed for the determination of tramadol hydrochloride. The SWV method enables the determination of tramadol over the concentration range of 15-75 µM with a detection limit of 2.2 µM. Tramadol could be determined in concentrations between 9 and 50 µM at a sampling rate of 90 h-1, with a detection limit of 1.7 µM using the flow injection system. The electrochemical methods developed were successfully applied to the determination of tramadol in pharmaceutical dosage forms, without any pre-treatment of the samples. Recovery trials were performed to assess the accuracy of the results; the values were between 97 and 102% for both methods.
