Greater Amman: metropolitan growth and scenarios for sustainable urban development

This paper reviews the development of Greater Amman, Jordan noting that the vast urban expansion that has occurred over the last fifty years has led to the desertification of rare fertile lands, following the fragmented and scattered territorial expansion of the city. The future scenario for planning in Greater Amman is analyzed in respect of proposals outlined in the Metropolitan Growth Plan of 2008, which assumes a rapid population growth from 2,200,000 persons in 2006, to approximately 6,500,000 by 2025. The concentration of more than 39 per cent of the national population of Jordan in Greater Amman threatens the transformation of former distinct settlement pattern into a distinctive continuous urban zone, aggravating problems of infrastructural provision, water needs, agricultural lands, and leaving unresolved problems of land inflation, poor urban standards and housing shortages. In conclusion, the environmental implications of the Amman Metropolitan Growth Plan are analysed, and it is suggested that an alternative approach is needed, based on clear principles of sustainable urban development.

Combined use of satellite estimates and rain gauge observations to generate high-quality historical rainfall time series over Ethiopia

Climate data are used in a number of applications including climate risk management and adaptation to climate change. However, the availability of climate data, particularly throughout rural Africa, is very limited. Available weather stations are unevenly distributed and mainly located along main roads in cities and towns. This imposes severe limitations to the availability of climate information and services for the rural community where, arguably, these services are needed most. Weather station data also suffer from gaps in the time series. Satellite proxies, particularly satellite rainfall estimate, have been used as alternatives because of their availability even over remote parts of the world. However, satellite rainfall estimates also suffer from a number of critical shortcomings that include heterogeneous time series, short time period of observation, and poor accuracy particularly at higher temporal and spatial resolutions. An attempt is made here to alleviate these problems by combining station measurements with the complete spatial coverage of satellite rainfall estimates. Rain gauge observations are merged with a locally calibrated version of the TAMSAT satellite rainfall estimates to produce over 30-years (1983-todate) of rainfall estimates over Ethiopia at a spatial resolution of 10 km and a ten-daily time scale. This involves quality control of rain gauge data, generating locally calibrated version of the TAMSAT rainfall estimates, and combining these with rain gauge observations from national station network. The infrared-only satellite rainfall estimates produced using a relatively simple TAMSAT algorithm performed as good as or even better than other satellite rainfall products that use passive microwave inputs and more sophisticated algorithms. There is no substantial difference between the gridded-gauge and combined gauge-satellite products over the test area in Ethiopia having a dense station network; however, the combined product exhibits better quality over parts of the country where stations are sparsely distributed.

On the clustering of winter storm loss events over Germany

During the last decades, several windstorm series hit Europe leading to large aggregated losses. Such storm series are examples of serial clustering of extreme cyclones, presenting a considerable risk for the insurance industry. Clustering of events and return periods of storm series for Germany are quantified based on potential losses using empirical models. Two reanalysis data sets and observations from German weather stations are considered for 30 winters. Histograms of events exceeding selected return levels (1-, 2- and 5-year) are derived. Return periods of historical storm series are estimated based on the Poisson and the negative binomial distributions. Over 4000 years of general circulation model (GCM) simulations forced with current climate conditions are analysed to provide a better assessment of historical return periods. Estimations differ between distributions, for example 40 to 65 years for the 1990 series. For such less frequent series, estimates obtained with the Poisson distribution clearly deviate from empirical data. The negative binomial distribution provides better estimates, even though a sensitivity to return level and data set is identified. The consideration of GCM data permits a strong reduction of uncertainties. The present results support the importance of considering explicitly clustering of losses for an adequate risk assessment for economical applications.

Gli studi italiani sulla regina Cristina di Svezia negli ultimi cinquant'anni

Queen Christina of Sweden (1626-1689)) is probably the most important individual to directly link the cultures of Sweden and Italy, and thus fascinate scholars over the last four centuries. In the last fifty years, research on and interest in this monarch has been particularly intense. This has led to current international scientific debate concerning all the different cultural expressions in which Queen Cristina was particularly involved. However, until now there has been lacking a comprehensive work to illustrate the development of scientific research in Italian on Queen Christina. This article, therefore, without claiming to be exhaustive, aims to fill this gap by identifying the main direction of current research. The article, after briefly introducing previous works (both Italian and Swedish), demonstrates how the first major renaissance of international studies on Queen Cristina took place in Sweden in the early 1960s. Even more important was the subsequent turning point in 1989, when the tercentenary of the death of Queen Christina was celebrated and the Azzolino Collection at the Biblioteca Comunale in Jesi was opened. The article focuses on the studies in Italian during this latter period. To make the exposition more organic and, importantly, more accessible to those readers interested in only one particular aspect of the scientific studies about Queen Christina, the studies in Italian since 1689 are divided into different subject areas.

Fatores pré-operatórios associados à injúria renal aguda após cirurgia cardíaca: estudo prospectivo

OBJECTIVES. To evaluate the clinical characteristics and co-morbidities associated with development of Acute kidney injury (AKI) after cardiac surgery in patients of a predominantly tertiary care university hospital.METHODS. One hundred and fifty cardiac surgery patients were prospectively studied at the Botucatu School of Medicine, University Hospital- UNEP, using a protocol which started 48h before and finished 48h after surgery, AKI was defined as a 30% increase in baseline serum creatinine.RESULTS. Were expressed as mean +/- standard deviation or median, with a significance level of 5%. Results: There was a slight male predominance (57%); mean age of the studied population, was 56 +/- 14 years. Sixty-five per cent of patients underwent myocardial revascularization. AKI was diagnosed in 34% of cases, Multivariate analysis showed that age over 60 years and peripheral vascular disease were significant associated with AKI developmentCONCLUSION. AKI was a common complication in cardiac surgery patients at this hospital, AKI was associated with age over 60 years and presence of peripheral vascular disease.

Considerations about enamel microabrasion after 18 years

Purpose: To review of the current status of enamel microabrasion method and its results 18 years after the development and application of this method. Methods: A technique performing enamel microabrasion with hydrochloric acid mixed with pumice and other techniques employing a commercially available compound of hydrochloric acid and fine-grit silicon carbide particles in a water-soluble paste have been described. Much has been learned about the application of this esthetic technique, long-term treatment results and microscopic changes to the enamel surface that has significant clinical implications. The latest treatment protocol is presented and photographic case histories document the treatment results. Clinical observations made over 18 years are discussed. Results: According to our findings, the dental enamel microabrasion technique is a highly satisfactory, safe and effective procedure.

O uso das pregas cutâneas e da circunferência muscular do braço no diagnóstico de desnutrição energético-protéica em pacientes adultos: estudo crítico.

The use of anthropometric measurements of triceps (TSF) and subscapular skinfolds (SSF) and mid-upper arm muscle circumference (MAMC) was examined as far as the diagnosis of energy-protein malnutrition (EPM) is concerned. The study was undertaken in five groups of patients (n = 231): arterial hypertension (AH, n = 63), chronic obstructive pulmonary disease (COPD, n = 17), hemodialyzed chronic renal failure (CRF, n = 19), critically ill patients with an acute event (CA, n = 42) and critically ill patients with chronic diseases (CCD, n = 90). The results were compared to those obtained in a group of healthy individuals (control group, n = 102). The control group and the group of patients were allocated in subgroups according to sex and age (less than 50 and more than 50 years). It was expected that significant differences would be found for the anthropometric values between the control subgroups and the COPD, the CRF and the CCD subgroups of patients. For the skinfold thicknesses (TSF and SSF), significant differences were found between CRF, CCD subgroups and the control subgroups under fifty years of age; however, the differences were not significant when the subgroups over fifty were analyzed. Concerning the MAMC, significant differences were found: 1 degree) between the CRF subgroups (males and females) and the control subgroups under fifty years of age; 2 degrees) between the CCD male subgroups (younger and older subgroups) and the respective control subgroups and 3 degrees) between the COPD and the control subgroups.(ABSTRACT TRUNCATED AT 250 WORDS)

The natural history of carpal tunnel syndrome: A study of 20 hands evaluated 4 to 9 years after initial diagnosis

Carpal tunnel syndrome (CTS) is the most frequent entrapment neuropathy. In the last decade several papers have been published on epidemiology, clinical aspects, diagnosis, and treatment, but little is known about its natural history. The objective of this work was to study the natural history of CTS syndrome. From 358 patients with clinical and conduction study diagnosis of CTS, 12 cases were identified that had refused surgical treatment, had not used anti-inflammatory medications, and had not undergone orthopaedic procedures, such as immobilization or anaesthetic infiltration. These 12 patients have 20 compromised hands which have been followed up for between 4 and 9 years. In all cases sensory and motor conduction studies were performed on the median nerve, at the beginning and end of follow-up period. Electrical improvement was marked in 5 hands and slight in 3; there was no significant change in 10, and deterioration in 2. As 8 hands (7 patients) showed improved clinical symptoms and conduction studies over several years, this brings the universally accepted procedure of surgical treatment into doubt.

Convergências e/ou divergências no sistema de crenças e práticas parentais: comparação entre duas amostras amazônicas

A proposta desta pesquisa foi identificar convergências e divergências nas crenças, metas de socialização e práticas de cuidados parentais em dois contextos ecológicos amazônicos, buscando analisar a relação entre fatores biológicos e ecoculturais. Participaram da pesquisa 99 mães de duas localidades: Belém – capital (CEU – contexto ecológico urbano – N=50) e Santa Bárbara (CENU – contexto ecológico não urbano – N=49), com idade superior a 18 anos com pelo menos uma criança com idade entre 0 e 6 anos . Os dados foram coletados por meio de entrevistas em que se aplicavam questionários e para análise destes foram utilizados critérios estatísticos e o respaldo teórico da Psicologia Evolucionista. Os dados indicaram que as comunidades estudadas em relação aos dados socio-demográficos diferem de forma sistemática uma da outra, em função dos níveis de desenvolvimento tecnológico e diferentes organizações para o contexto social. O mundo social das crianças de CENU e de CEU representam contextos desenvolvimentais que oferecem diferentes oportunidades. A literatura aponta que as trocas sociais estabelecidas entre crianças e cuidadores podem refletir sobre o desenvolvimento da criança em relação ao aspecto cognitivo, emocional e social. Os resultados encontrados indicam que as mães de CEU apesar de terem sido mais autônomas que as de CENU, foram ao mesmo tempo mais relacionais que as mesmas, demonstrando que talvez as mudanças que atingem os contextos, ocorram com mais rapidez em ambientes urbanizados. Além disso, os dados parecem indicar que os contextos por estarem em um momento de transição passam de um modelo interdependente para um modelo autônomo-relacional. Entretanto, foi possível perceber que as idéias que as mães possuem sobre a importância de determinadas ações nem sempre refletem suas práticas. Em relação aos cuidados primários as mães parecem valorizar e realizar de igual modo. Em relação ao Contato corporal as mães de CENU valorizam mais que as mães de CEU. Em estimulação corporal o resultado foi bastante interessante, pois os itens que CEU deu mais importância e praticou menos, foram os mesmos itens em que CENU deu menos importância e praticou mais. No que tange a estimulação por objeto as mães de CEU dão mais importância as praticas do que as realizam e vice-versa acontece em CENU. Ao sistema face-a-face foi atribuída maior importância pelas mães de CEU. Os dados apresentados sugerem que as mães de ambos os contextos estão utilizando estratégias parentais distais e proximais ao mesmo tempo, ou seja, desejam que seus filhos se tornem auto-suficientes, mas também desejam que os mesmos sejam respeitosos e obedientes. Além disso, os resultados aqui encontrados confirmam que os quatro sistemas descrevem as experiências interacionais das crianças e expressam a ênfase cultural de combinações e estilos particulares. Não foram encontradas diferenças marcantes nas crenças e práticas de cuidados maternos entre CEU e CENU, o que nos levou a considerar que as crenças parentais, em consequência à adaptação ao contexto, variaram menos conspicuamente nas cidades escolhidas do que entre outras cidades examinadas em outros estudos. Outra questão bastante interessante encontrada foi o resultado relativo ao nível de instrução das mães de CEU e a valorização de metas relacionais, pois de acordo com a hipótese na literatura o nível educacional das mães torna-se uma variável importante em relação às metas de socialização. CENU demonstrou uma tendência para metas e práticas relacionais. Isso se deve ao modo de vida mais próximo do protótipo de interdependência que este contexto apresenta, no qual as mães tendem a valorizar as normas e regras determinadas pela família ou grupo ao qual pertencem. Os resultados referentes ao CEU não confirmaram a hipótese de que ele apresentaria mais metas e práticas voltadas para a independência, sendo percebido que Belém apresenta tanto características do modelo de independência como de interdependência. Presume-se que CEU e CENU são contextos que passam por mudanças, uma vez que as mães podem acreditar em uma coisa e na realidade agir de outra forma.
