The global emission and accumulation of gases due to livestock farming is estimated to contribute to about 14.5% of the global warming effect due to greenhouse gases (GHG). Pig farming represents 9% of global livestock GHG emissions, without considering other activities of pork production process, such as feed production. Most of information about pig farms GHG emissions is based on theoretical calculations with not too much accuracy. Hence, there is a critical need to study the best sampling and analytical techniques (portable or not) that can be used to map their contribution to GHG emissions. The selection of the best analytical detection method becomes important for public policies on climate change, and in order to evaluate animal and manure handling practices to reduce GHG and to combat global warming. In this article, different techniques, which could be used to measure the emissions of GHG from livestock, are reviewed, showing the advantages and disadvantages of each technique, with special emphasis on those already used in studies about GHG from pig farms and those that allow the simultaneous determination of several species of gases. Open chambers equipped with photoacoustic multi-gas monitor have been the techniques most employed in intensive pig farms studies. Gas Chromatography coupled to different detectors has been only widely used in pig farms to monitor simultaneously several GHG species using previous sampling devices. However, there are no studies in the literature based on extensive pig farms. In these systems, micrometeorological techniques could be a promising strategy.

Background: The new special educational needs and disability legislation in England has introduced Education Health and Care plans as statutory documents for children with special educational needs, and has extended provision beyond compulsory education, placing transition in a compelling position. This policy recognises the need to include the views, wishes and aspirations of children and young people in the development of provision to cater for their needs. For young people with autism spectrum disorders and their families, transition to post-16 education and employment could be challenging. This study aimed to explore how voices of young people with autism spectrum disorders are captured in their Education Health and Care plans. Methods: These views were collected from the Education Health and Care plans of 12 young people with autism spectrum disorders. These plans were analysed inductively and deductively through content analysis, using the International Classification of Functioning, Disability and Health: Children and Youth Version as a coding framework. Results: Discrepancies were found between plans concerning the ways in which the voices of young people with ASD were elicited. A total of 189 functioning codes were identified, with a prevalence of activities and participation codes to reflect their views, followed by body functions and lastly environmental factors. Conclusion: These disparities are discussed in light of the biopsychosocial model of functioning and health, and the new English policy. Implications for adopting the International Classification of Functioning framework to give voice to young people with autism spectrum disorders are also discussed.Implications for rehabilitationYoung people with autism spectrum disorders face many challenges in their transition to post-16 education and employment.Engaging young people with autism spectrum disorders in matters that affect their own lives contribute to the development of provision that is aligned with their wishes and aspirations.Practitioners collaborating in the development of Education Health and Care plans should ensure that young people are effectively involved in the development of their own plans.The International Classification of Functioning, Disability and Health, Children and Youth Version provides a systematic framework and language for coding and recording data from different sources with which to capture young people's views.

Background: A crucial issue in special educational needs and disability policy and provision is the documentation of children's functioning, for which many countries have a statutory document. In England this is the education health and care plan. Recent research challenges the quality of these plans. Purpose: To provide evidence on the usefulness of the international classification of functioning, disability and health as a system with potential to support the development of higher quality plans in England. Methods: Twenty-five professionals participated in a one-day training session on the international classification of functioning disability and health, with a focus on designing higher quality SMART targets to be included in children's plans. Results: Overall, participants regarded the system as useful. Comparison of targets written before and after the training show improvements in relevance, specificity and on the extent to which they were action-oriented and measurable. Conclusions: Results are discussed in light of international lessons learned around the potential of the international classification of functioning disability and health to support policy change. A "no policy is an island" approach is proposed, suggesting local policy-makers should open horizons beyond geographical boundaries in evidence-based decision-making for supporting children with disabilities.Implications for rehabilitationThe ICF can be regarded as a useful framework for supporting professionals developing targets for children with Education Health and Care (EHC) plans in England.For developing SMART targets with the ICF, professionals can use the taxonomy to look for detailed aspects of functioning, relevant to a certain developmental stage.Using the ICF can support in making more measurable targets in EHC plans if the universal qualifier scale is applied when describing detailed aspects of functioning.Professionals trained on the ICF recognise its usefulness for writing EHC targets.More in-depth training is recommended for supporting the development of more holistic biopsychosocial EHC plans in England.
