Relationship between socioeconomic deprivation or urban/rural residence and visual acuity before cataract surgery in Northern Scotland

Purpose: To evaluate the influence of socioeconomic factors on visual acuity before cataract surgery. ?Methods: The medical case notes of 240 consecutive patients listed for cataract surgery from January 1, 2010, at Grampian University Hospital, Aberdeen, were reviewed retrospectively. Patients with ocular comorbidity were excluded. Demographics, postal codes, and visual acuity were recorded. Scottish Index of Multiple Deprivation was used to determine the deprivation rank. Home location was classified as urban or rural. The effect of these parameters on preoperative visual acuity was investigated using chi-square tests or Fisher exact test as appropriate. ?Results: A total of 184 patients (mean 75 years) were included. A total of 127 (69%) patients had visual acuity of 6/12 or better. An association was found between affluence and preoperative visual acuity of 6/12 or better (?2trend = 4.97, p = 0.03), with a significant rising trend across quintile of deprivation. There was no evidence to suggest association between geographical region and preoperative visual acuity (p = 0.63). ?Conclusion: Affluence was associated with good visual acuity (6/12 or better) before cataract surgery. There was no difference in preoperative visual acuity between rural and urban populations.

Temporary tattoos:a novel OSCE assessment tool

Background: There are many issues regarding the use of real patients in objective structured clinical examinations (OSCEs). In dermatology OSCE stations, standardised patients (SPs) with clinical photographs are often used. Temporary transfer tattoos can potentially simulate skin lesions when applied to an SP. This study aims to appraise the use of temporary malignant melanoma tattoos within an OSCE framework. Method: Within an 11-station OSCE, a temporary malignant melanoma tattoo was developed and applied to SPs in a 'skin lesion' OSCE station. A questionnaire captured the opinions of the candidate, SP and examiners, and the degree of perceived realism of each station was determined. Standard post hoc OSCE analysis determined the psychometric reliability of the stations. Results: The response rates were 95.9 per cent of candidates and 100 per cent of the examiners and SPs. The 'skin lesion' station achieved the highest realism score compared with other stations: 89.0 per cent of candidates felt that the skin lesion appeared realistic; only 28 per cent of candidates had ever seen a melanoma before in training. The psychometric performance of the melanoma station was comparable with, and in many instances better than, other OSCE stations. Discussion: Transfer tattoo technology facilitates a realistic dermatology OSCE station encounter. Temporary tattoos, alongside trained SPs, provide an authentic, standardised and reliable experience, allowing the assessment of integrated dermatology clinical skills.

Temporary Places > Community Garden > Peaspark

Temporary Places is a community and art project in North Belfast at two interface areas, New Lodge and Skegoneill/ Glandore. This project (Jan 2013-ongoing) is a collaboration between New Lodge Arts
(lead administrative partner), PS2 (project curators) and Skegoneill & Glandore Common Purpose (community organisation). ‘Temporary Places’ was and still is a project about social and urban regeneration, partly through familiar strategies and activities and partly through more unorthodox, direct and creative interventions. It is an art and community project for all residents and the wider community.

There are several components to the project, but the key and ongoing element is to activate the empty spaces at the Skegoniell / Glandore Interface, by making a 'garden space' of creative activity - now known as Peaspark

Theorizing temporary spatial clusters and institutional boundary-work in industrial markets

To better understand the nature of temporary spatial clusters (TSC’s) in industrial marketing settings, this conceptual paper first provides a theoretical synthesis of spatial understanding from the industrial marketing (IM) and economic geography (EG) fields, focusing particularly on Doreen Massey’s work on relational space. This leads to a conceptual schema for organizing the IM literature in terms of spatiality, and which also helps clarify the ontological nature of TSCs. We then move to introduce the notion of institutional boundary-work, drawing on the work of Thomas Gieryn, and Andrea Brighenti’s examination of territorology, to conceptualize the activities of market actors engaged in the ongoing social accomplishment of TSCs. Such activities, we suggest, involve these actors ‘marching’ boundaries to assume network influence and maintain market order in IM settings. In summary, therefore, our paper addresses two fundamental questions: i) How do we conceptualize the form of TSCs in IM settings? And, ii) what function(s) are TSCs performing (and how is this being undertaken) in IM? The paper closes by providing methodological guidance for how a research agenda on TSCs within IM activity might be developed, followed by a summary of the managerial implications that emerge from our theorizations.

Hidroquímica e qualidade das águas subterrâneas da Ilha de Santiago - Cabo Verde

A ilha de Santiago, Cabo Verde é uma ilha de origem vulcânica, constituída basicamente por lavas e piroclastos, localizada no Oceano Atlântico ao lado da costa ocidental de África. A ilha é caracterizada por três unidades hidrogeológicas, sendo estas a Formação de Base (semi-confinada), a Formação Intermédia (freática) e a Formação Recente (freática), que apresentam características geológicas e comportamentos hidráulicos que as diferenciam, recebendo recarga directa e/ ou diferida por infiltração das águas de chuva e descarregam ao mar, na rede hidrográfica ou, ainda, em outros níveis aquíferos subjacentes, desde que induzidos por gradientes hidráulicos favoráveis. O clima de Santiago é árido a semi-árido, com precipitações muito escassas e irregulares, condicionadas na sua distribuição pela altitude, ventos e orientação das vertentes, dando por vezes origem a períodos de seca prolongados. Em anos de ‘boa’ chuva, as precipitações propiciam a existência temporária de recursos hídricos superficiais e a recarga dos recursos de água subterrânea. Foi realizado um estudo hidrogeoquímico detalhado da ilha que incluiu a recolha de amostras em 133 pontos de água, entre furos, poços e nascentes. A composição química das águas analisadas na ilha de Santiago apresenta significativas variações em função da geologia e do tempo de residência. Na ausência de episódios de contaminação, as águas subterrâneas têm uma composição do tipo bicarbonatada-sódica (HCO3-Na) nas zonas mais altas da ilha, onde afloram as formações da Unidade Aquífera Intermédia. Nas zonas mais próximas da costa ocorrem águas de composição cloretada-magnesiana (Cl-Mg) ou cloretada-sódica (Cl-Na). Estas últimas predominam nas partes terminais das ribeiras, onde afloram materiais de elevada permeabilidade, e o excesso de bombagem para irrigação tem conduzido a um avanço da cunha de intrusão marinha. A ocorrência da fácies Cl-Na é neste caso o resultado de processos de intercâmbio catiónico que ocorrem durante o processo de intrusão e é concordante com os elevados teores de cloretos e de condutividade eléctrica observados. Os resultados das análises de isótopos estáveis de oxigénio-18 e deutério, realizadas em amostras recolhidas a distintas altitudes, revelam um gradiente negativo com a altitude, que já tinha sido verificado em outras ilhas com declives acentuados, permitindo assim determinar altitudes de recarga de água subterrânea. Os estudos hidrogeoquímicos até agora realizados permitiram caracterizar os principais níveis aquíferos da ilha de Santiago, colocando em evidência a limitada recarga do aquífero e o risco de gradual degradação dos recursos de água subterrânea por fenómenos de intrusão salina e contaminação agrícola. Estes resultados revelam a importância da gestão integrada da qualidade e quantidade dos parcos recursos de água subterrânea na ilha de Santiago.

A methodology to estimate the residence time of estuaries

The residence time has long been used as a classification parameter for estuaries and other semi- enclosed water bodies. It aims to quantify the time water remains inside the estuary, being used as an indicator both for pollution assessment and for ecological processes. Estuaries with a short residence time will export nutrients from upstream sources more rapidly then estuaries with longer residence time. On the other hand the residence time determines if micro-algae can stay long enough to generate a bloom. As a consequence, estuaries with very short residence time are expected to have much lower algae blooms, then estuaries with longer residence time. In addition, estuaries with residence times shorter than the doubling time of algae cells will inhibit formation of algae blooms (EPA, 2001). The residence time is also an important issue for processes taking place in the sediment. The fluxes of particulate matter and associated adsorbed species from the water column to the sediment depends of the particle’s vertical velocity, water depth and residence time. This is particularly important for the fine fractions with lower sinking velocities. The question is how to compute the residence time and how does it depend on the computation method adopted.

Residence Model

Model layout of the 3 stage residence expansion to the university proposed in September of 1967. This was a revision of the original master plan which called for high rise residences east of the Tower rather then the sprawling residences shown here. Although modified slightly from the model, the first stage of the residence would become a reality in the form of the Decew Residence. The realization of the second stage would also eventually take place when the Gordon and Betty Vallee Residence was constructed.

Glenridge Residences

In 1968 Brock University purchased 5 quadruplexes on Glenridge Avenue to serve as Brock's first student residences. Three additional units were later purchased and in total these first residences could accommodate around 150 students. They were used as temporary residences until the Decew Residence was completed.
