There are many challenges in evaluating international networks. The use of conventional tools can be difficult and often provides less than useful information. Social Network Analysis offers benefits for network evaluators by allowing for documentation and analysis of inter-relationships between individuals and organisations. This paper describes the use of this approach in the evaluation of a major international project entitled the Global Dialogues on Sexual Health and Well-being. It highlights the value of maps in enabling clear visual representations of networks, the identification of areas needing greater focus and the basis on which networks are constructed.
Analyse des réseaux sociaux pour évaluer les réseaux organisationnels sur les droits et la santé génésiques
L’évaluation des réseaux internationaux présente de nombreux défis. L'utilisation d'outils conventionnels peut être difficile et fournit souvent des informations qui ne sont pas des plus utiles. L'analyse des réseaux sociaux comporte des avantages pour les évaluateurs des réseaux, car elle permet la documentation et l'analyse des corrélations entre individus et organisations. Cet article décrit l'utilisation de cette approche dans l’évaluation d'un important projet international intitulé Global Dialogues on Sexual Health and Wellbeing (Dialogues mondiaux sur la santé et le bien-être génésiques). Il met en relief la valeur des cartes pour permettre des représentations visuelles claires des réseaux, l'identification de zones nécessitant un axe central plus marqué et la base sur laquelle les réseaux sont construits.
Análise de Rede Social para avaliar redes organizacionais sobre saúde sexual e direitos
Existem muitos desafios para se avaliar as redes internacionais. O uso de ferramentas convencionais pode ser dificil e frequentemente oferece informações que não são úteis. A Análise de Rede Social oferece benefícios para avaliadores de rede ao considerar a documentação e análise das inter-relações entre indivíduos e organizações. Este artigo descreve o uso desta abordagem na avaliação de um grande projeto internacional chamado Diálogos Globais sobre Saúde Sexual e Bem-Estar. Ele destaca o valor de mapas para permitir representações visuais claras de redes, a identificação de áreas que estejam precisando de um maior enfoque e a base sobre a qual as redes são construídas.
El Análisis de Redes Sociales para evaluar redes de organizaciones que trabajan en salud y derechos sexuales
A la hora de evaluar las redes internacionales surgen muchos retos. Los métodos tradicionales pueden presentar dificultades y a menudo proporcionan información poco útil. El Análisis de Redes Sociales presenta ventajas para los evaluadores de redes ya que ofrece la posibilidad de documentar y analizar relaciones entre individuos y organizaciones. El presente ensayo examina cómo se utilizó este método para evaluar un importante proyecto internacional llamado “Diálogos globales sobre salud sexual y bienestar”. También ilustra cómo los mapas son valiosos porque muestran una clara representación visual de las redes, revelan las áreas que necesitan mayor atención y señalan las bases sobre las que se construyen las redes. 相似文献
This study provides an update on a quantitative method for immature age estimation based on postnatal deciduous mandibular tooth length. Two known sex and age skeletal collections from Western Europe were sampled (n = 97). Linear regression models for age estimated were calculated for each individual tooth, each sex, and sex combined sample using classical calibration. Prediction errors, residuals, and percentage of individuals whose real age fell within the 95% prediction interval were calculated. The teeth which develop earlier in life, the incisors and the first molar, showed the greatest precision, while the canine showed the least. This method has greater applicability to archeological skeletons or to children in developing countries than for use in North American or European forensic contexts. The method can be applied to incomplete or poorly preserved remains of unknown sex, particularly when dental radiographs are not an option or when teeth have been removed from the alveolus or crypt. 相似文献
Gunshot Residue (GSR) produced by the discharge of a firearm often provides very useful information in criminal investigations in cases involving the use of firearms. Scanning Electron Microscopy equipped with an Energy Dispersive X-ray Spectrometer (SEM-EDS) is typically used worldwide to visualize micrometric particles constituting GSR and to analyse their elemental composition. The 2017 ASTM Standard guide for gunshot residue analysis by scanning electron microscopy/energy dispersive X-ray spectroscopy specifies that “Particles classified as characteristic of GSR will have one of the following elemental compositions: Lead, antimony, barium; Lead, barium, calcium, silicon, tin”. For the first time, the presence of an additional element, such as Sn, plays a key role in ASTM particle classification. It is known that some ammunitions, used for pistols, revolvers and rifles, contain tin foil discs for sealing the primer mixture into the cup, resulting in GSR particles containing Sn. The authors faced some cases in which Sn was unexpectedly found in GSR particles from a 0.22 Long Rifle derringer and from some 12 gauge shotguns. No tin foil discs are used in rimfire ammunitions and there is no published evidence of tin foil discs in shotshell ammunitions. Following a “case by case” approach, experimental research has been carried out to explain how Sn can be present in GSR particles when the last discharged cartridge also does not contain any Sn either in components and in the explosive charges.Moreover, the use of Particle Induced X-ray Emission (PIXE) showed the capability to overcome overlap ambiguity of Sb and Sn peaks in the X-ray spectra, being a possible key issue in real shooting cases if Sn quantities are below the lower limit of SEM detection, especially when Sb is also present. 相似文献
It is a known fact that when fabric is left exposed to sunlight photodegradation occurs. However, no study has ever looked at the photodegradation that occurs to individual fibre filaments as commonly recovered from a scene of crime. To look at photodegradation of individual fibres, wool and cotton fabric were dyed using CI Acid Red 27 and CI Direct Red 80 respectively at two depths of shade, 0.25% and 2.0% owf. Pieces of fabric and individual fibre samples were then placed in a Light Fastness Q-Sun 1000 Xenon test chamber which simulated exposure to sunlight over two time periods, 64 h (equivalent to one weeks sun exposure) and 128 hrs (equivalent to two weeks sun exposure). The resulting pieces of fabric and fibres where then examined using high power comparison microscopy, as well as graded for colour fading using SDC Grey Scale for Assessing Change in Colour (including half steps). Results show that in both fibre types, photodegradation occurs in all samples, however, the degree of fading is shown to vary within a given fibre population showing it is unpredictable in nature. 相似文献
In the lead-up to the Paris Agreement, every country was invited to submit an intended nationally determined contribution (INDC), and indicate how it is fair. We analyse how countries have explained the equity of mitigation and adaptation in 163 INDCs, providing a bottom-up analysis of equity to complement a literature that has focused on top-down allocations. While no single indicator of equity was used by all INDCs, a menu of quantified indicators or tiered approaches could provide bounded flexibility across different national circumstances. The most common equity indicator used in mitigation INDCs is the country’s ‘small share’ of global emissions, followed by per capita emissions. The emissions of individual ‘small share’ INDCs add up to 24% of annual global emissions when using a consistent data set. Per capita emissions are used across a range of countries with low (0.5) to high (25 t CO2–eq per capita) values for that indicator. Adaptation is included in 89% of INDCs, of which more than half quantify impacts in some manner, and two-thirds use vulnerability as an equity argument. Broadly, we find that most claims to equity are either unsubstantiated or drawn from analysis by in-country experts. Only two INDCs refer to independent evidence, and none consider the consequences of their approach when applied to all countries. Given that the aggregate effect of INDCs will not be sufficient to keep global temperature increase well below 2 °C, and even less to keep temperature below a 1.5 °C rise, the INDCs have distributional implications. More rigorous information is needed to assess relative fair shares, which could be provided officially in future nationally determined contributions (NDCs). Absent improved information, it is likely that researchers and civil society will continue to assess informally what could be considered fair. A hybrid approach to equity—combining bottom-up assessment and top-down allocation—would be consistent with the hybrid architecture of the Paris Agreement, which comprises bottom-up elements such as NDCs and top-down elements such as global goals. Improved information on equity in NDCs will be an important input to the global stocktake ‘in the light of equity’. 相似文献
Jones and Baumgartner's punctuated equilibrium model of agenda change has reinvigorated decision-making theory; moreover their US budget project offers a set of techniques to apply to UK data. We replicate the method by plotting percentage budget changes in central government budgets to see whether the distribution is normally distributed as predicted by the incrementalist account or leptokurtic as hypothesized by the punctuated equilibrium model. Taking the period 1951–96, we create 405 data points from budget changes from the National Income Accounts ('Blue Book') on agriculture, defence, social security, education, health, housing, industry, law and order and transport, all adjusted using the GDP deflator at factor cost. We find that the budget changes form a leptokurtic distribution. Such a pattern appears in most policy sectors. 相似文献
