Extreme Precipitation Modelling Using Geostatistics and Machine Learning Algorithms

The paper presents an approach for mapping of precipitation data. The main goal is to perform spatial predictions and simulations of precipitation fields using geostatistical methods (ordinary kriging, kriging with external drift) as well as machine learning algorithms (neural networks). More practically, the objective is to reproduce simultaneously both the spatial patterns and the extreme values. This objective is best reached by models integrating geostatistics and machine learning algorithms. To demonstrate how such models work, two case studies have been considered: first, a 2-day accumulation of heavy precipitation and second, a 6-day accumulation of extreme orographic precipitation. The first example is used to compare the performance of two optimization algorithms (conjugate gradients and Levenberg-Marquardt) of a neural network for the reproduction of extreme values. Hybrid models, which combine geostatistical and machine learning algorithms, are also treated in this context. The second dataset is used to analyze the contribution of radar Doppler imagery when used as external drift or as input in the models (kriging with external drift and neural networks). Model assessment is carried out by comparing independent validation errors as well as analyzing data patterns.

Equality Impact Assessment of the Sure Start Programme (PDF 18 KB)

This Equality Impact Assessment (EQIA) addresses the Sure Start programme which was introduced in Northern Ireland during 2000/01. Section 75 of the Northern Ireland Act 1998 requires all public authorities in carrying out their functions relating to Northern Ireland to have due regard to the need to promote equality of opportunity: - • between persons of different religious belief, political opinion, racial group, age, marital status or sexual orientation; • between men and women generally; • between persons with a disability and persons without; and • between persons with dependants and persons without. åÊ

Implementing the ICT Strategy

Activity in inferior parietal and medial prefrontal cortex signals the accumulation of evidence in a probability learning task.

In an uncertain environment, probabilities are key to predicting future events and making adaptive choices. However, little is known about how humans learn such probabilities and where and how they are encoded in the brain, especially when they concern more than two outcomes. During functional magnetic resonance imaging (fMRI), young adults learned the probabilities of uncertain stimuli through repetitive sampling. Stimuli represented payoffs and participants had to predict their occurrence to maximize their earnings. Choices indicated loss and risk aversion but unbiased estimation of probabilities. BOLD response in medial prefrontal cortex and angular gyri increased linearly with the probability of the currently observed stimulus, untainted by its value. Connectivity analyses during rest and task revealed that these regions belonged to the default mode network. The activation of past outcomes in memory is evoked as a possible mechanism to explain the engagement of the default mode network in probability learning. A BOLD response relating to value was detected only at decision time, mainly in striatum. It is concluded that activity in inferior parietal and medial prefrontal cortex reflects the amount of evidence accumulated in favor of competing and uncertain outcomes.

Equality Programme for Health, Social Services and Public Safety (PDF 181KB)

The Department of Health, Social Services and Public Safety (HSSPS), like all public authorities, is required under Section 75 of the Northern Ireland Act 1998 (‘the Act’) in carrying out its functions, powers and duties, to have due regard to the need to promote equality of opportunity and good relations among 9 specific categories of people. In fulfilling these obligations, the Department is required to submit its policies and programmes to formal assessment of the equality implications arising from them through Equality Impact Assessments (EQIAs). åÊ

Breast and cervical cancer screening programme implementation in 16 countries.

OBJECTIVES: There is a continuing need to monitor and evaluate the impact of organized screening programmes on cancer incidence and mortality. We report results from a programme assessment conducted within the International Cancer Screening Network (ICSN) to understand the characteristics of cervical screening programmes within countries that have established population-based breast cancer screening programmes. METHODS: In 2007-2008, we asked 26 ICSN country representatives to complete a web-based survey that included questions on breast and cervical cancer screening programmes. We summarized information from 16 countries with both types of organized programmes. RESULTS: In 63% of these countries, the organization of the cervical cancer screening programme was similar to that of the breast cancer screening programme in the same country. There were differences in programme characteristics, including year established (1962-2003 cervical; 1986-2002 breast) and ages covered (15-70+ cervical; 40-75+ breast). Adoption of new screening technologies was evident (44% liquid-based Pap tests; 13% human papillomavirus (HPV)-triage tests cervical; 56% digital mammography breast). There was wide variation in participation rates for both programme types (<4-80% cervical; 12-88% breast), and participation rates tended to be higher for cervical (70-80%) than for breast (60-70%) cancer screening programmes. Eleven ICSN member countries had approved the HPV vaccine and five more were considering its use in their organized programmes. CONCLUSION: Overall, there were similarities and differences in the organization of breast and cervical cancer screening programmes among ICSN countries. This assessment can assist established and new screening programmes in understanding the organization and structure of cancer screening programmes.
