eXplorer Publish "Vislets"

http://ncva.itn.liu.se/explorer/vislets?l=en

eXplorer has so far focused on tools that analyze and explore statistical data to discover trends and patterns. eXplorer now also addresses challenges in support of an integrated editorial and related authoring process with the goal to advance research critical to educational production and publishing. NCVA now introduces eXplorer Publisher for Web enabled publication of temporal and multidimensional statistical data, facilitating a seamless integrated authoring tool (eXplorer) and storytelling mechanism including automatic generation of HTML code to be embedded as a dynamic visualization with associate metadata “Vislet” into blogs, wikis etc. See embedded OECD EU demonstrator below.

This novel “storytelling” framework provides means for the analyst and author to:
  • Select any spatio-temporal and multidimensional national or sub-national statistical data
  • Explore and discern trends and patterns
  • Orchestrate and describe metadata
  • Collaborate with colleagues to confirm
  • Publish essential gained insight and knowledge embedded as dynamic visualization “Vislet” in blogs or wikis with associate metadata
storytelling loop
Figure: The analyst (author) uses eXplorer to 1) import any national or sub-national statistical data, 2) explore and make discoveries through trends and patterns and derive insight. Gained knowledge is the foundation for 3) creating a story that can be 4) shared with colleagues and reach consensus and trust. The visual discoveries are captured into snapshots together with descriptive metadata and hyperlinks in relation to the analytics reasoning. The author gets feedback from colleagues, adopts the story and 5) finally publishes “tell-a-story” to the community using a “Vislet” that is embedded in blogs or wikis.
This seamless integration (figure) of an authoring, storytelling and publishing solution is based on experience and prototypes developed by NCVA during the last decade and can now advance the state of the art in statistical geovisualization publishing facilitating:
  • Authoring: data provider (spreadsheet and database), data manager, choropleth map, scatter plot, table lens, parallel coordinates plot (PCP), time graph, data grid, coordinated views, map layers, analytic tools (dynamic query, filter, regional categorization, profiles, highlight, motion charts), advanced dynamic colour scale and legend, create HTML code for Vislet.
  • Storytelling: snapshot mechanism, metadata with hyperlinks, story and chapters, edit, capture, save, export story, embed story.
  • Vislet: embeddable interactive motion visual representations based on statistical data including choropleth map, scatter plot, parallel coordinates (profile plot), table lens and metadata for publishing in blog, wikis etc. HTML code that characterizes the story-to-be-told is automatically created by the eXplorer authoring tool.

eXplorer storytelling tool


Figure: From creating a time-dependent story with the authoring tool “OECD eXplorer” to a published Vislet embedded in a Web page with dynamic temporal visualization, associate metadata and hyperlinks. This three-step approach that seamless integrates tools for “story authoring” and “story telling” provides an educational platform for analysts to publish interactive temporal statistics news.

Sweden shows positive growth in number of nights spent at hotels

From: Tourism in Europe: first results for 2009

First results for 2008-2009 evolution of tourism in Europe, focusing on nights spent in collective accommodation establishments, but also looking at holiday trips made by EU residents. 




In all countries except Sweden a negative growth in number of nights spent at hotels and similar establishments was observed. Looking at the total collective accommodation sector, only The Netherlands recorded a positive growth in 2009.

Social transfers are second most effective in Sweden

From: 17 % of EU citizens were at-risk-of-poverty in 2008

In 2008 as in 2007, 17% of the population was assessed to be at-risk-of-poverty following the concept of relative poverty adopted in the European Union. Despite this overall stability the risk of poverty rose by 5 percentage points in Latvia, and decreased significantly only in Ireland and Romania (both -2 percentage points). 20% of children were at-risk-of poverty in the EU in 2008 with the highest figures in Romania, Bulgaria, Italy, and Latvia. The at-risk-of-poverty rate exceeded 30% for the elderly population (aged 65 and more) in Latvia, Cyprus, Estonia and Bulgaria. On average, social protection reduced poverty by 32% in the EU with large discrepancies between countries. Holding a job is not always sufficient to escape from poverty and 8% of the EU population were at-risk-of-poverty in 2008 despite having a job. Material deprivation affected 17% of the EU population in 2008 and some of the new Member States (Bulgaria, Romania, Hungary, Latvia and Poland) recorded the highest values.
 
Chart 3 below ranks countries following the impact of social transfers on the at-risk-of-poverty rate before social transfers, in percentage of the latter.


In the absence of social transfers other than pensions, the poverty risk for the EU population as a whole would be considerably higher than it is in reality (25% instead of 17%): on average, social transfers reduce the risk of poverty by 32%.

Social transfers are most effective in Hungary, the Nordic countries (Sweden, Norway, Denmark and Finland), the Czech Republic, Ireland and Austria where they reduce poverty by 50% or more. Conversely, in Greece, Latvia, Spain and Italy, social transfers only reduce the risk of poverty by less than 20%.

Sweden highest share of renewables in energy consumption


From: Climate change and energy indicators

Data from July 2009, most recent data: Further Eurostat information, Database.
This article provides an overview of statistical data on sustainable development in the areas of climate change and energy. They are based on the set of sustainable development indicators the European Union (EU) agreed upon for monitoring its sustainable development strategy. Together with similarindicators for other areas, they make up the report 'Sustainable development in the European Union - 2009 monitoring report of the EU sustainable development strategy', which Eurostat draws up every two years to provide an objective statistical picture of progress towards the goals and objectives set by the EU sustainable development strategy and which underpins the European Commission’s report on its implementation.
Consumption of renewables has grown over the last decade but the share remains far from the target
During the 1990s the consumption of renewable energies in the EU-27 increased significantly and has continued to grow between 2000 and 2007. Th is resulted in a share of 7.8 % in 2007 which remains, however, substantially below the 12 % target for 2010. Even if the highest annual change of 8.3 % between 2006 and 2007 continued, the share of renewables would remain below the target.
Biomass is by far the most important renewable energy source, delivering almost 70 % of the total renewable energy in 2007 and having the fastest growing share. Hydro power is second in importance even though both its share and its absolute contribution have diminished between 2000 and 2007 due to a series of several very dry years. Wind and geothermal are still minor contributors and, although their absolute growth rates are increasing rapidly, their shares are only growing slowly.

Share of renewables in gross inland energy consumption, EU - Source: Eurostat (tsdcc110)
The proportion of renewables in gross inland energy consumption in 2007 varied widely between Member States. It ranged from 2.1 % in the UK to 29.7 % in Latvia and 30.9 % in Sweden, reflecting differences in resource base, mainly in respect to hydropower capacity and availability of biomass.
Biomass is the predominant renewable source, across all Member States, representing 5.4 % of EU-27 consumption in 2007. It provides 24.6 % of the gross inland energy consumption in Latvia, 19.3 % in Finland and 19.4 % in Sweden. Most of this is wood. In six Member States more than 90 % of renewable energy is derived from biomass. It is also the fastest growing share amongst renewable sources, due to the fact that biomass can be used in all three end-use sectors: power generation, transport and heating.
Second in overall importance is hydropower, which, however, not only decreased its share from 1.8 % to 1.5 % over the period 2000 to 2007 due to several very dry years, but also decreased in absolute terms. Wind and geothermal, whose shares have been growing at a very modest pace, are still relatively minor sources, together representing only 0.8 % of EU-27 energy consumption in 2007. In absolute terms, however, wind power capacity has been growing rapidly. It is now a significant renewable energy source in Spain, Denmark and Germany, where it makes up 22 %, 17 % and 12 % of renewables, respectively. Geothermal, generally another minor source, is the most important renewable energy source in Italy, where it represented 39 % of renewable energy in 2007. Solar energy remains the least important of all renewable energies in terms of its contribution. It represents 0.1 % of EU-27 gross inland energy consumption and 1.2 % of renewables, but its growth in absolute terms is impressive and solar energy constitutes an important renewable energy source in Cyprus and, to a lesser extent, in Greece with shares of 83 % and 10 % of total renewable energy.

Share of renewables in gross inland energy consumption, by country, 2007 (%) - Source: Eurostat (tsdcc110)
Measures aimed at reducing the growth in gross inland energy consumption, for example through energy savings and improving energy efficiency, will also influence the growth rate of this indicator.

Indicator relevance

Renewable energy sources are important for reducing the EU’s dependence on imported fossil fuels and cutting greenhouse gas emissions and other pollutants. In addition, a more mature market for renewable energy technologies is expected to bring about a number of social and economic benefits, including regional and local development opportunities, export opportunities and employment.
Two targets with different time horizons guide the EU effort to expand renewable capacity: the 1997 White Paper’s [2] goal to double the use of renewables in the European Union from 6 to 12 % between 1996 and 2010, and the 20 % renewables target for 2020 established in the recent Directive 2009/28/EC on the promotion of renewable energy. The 2010 target is set as percentage share of renewables in gross inland energy consumption. The 2020 target is defined as share of energy from renewable sources in gross final consumption and will require a different indicator [3].

Unlike the indicative target set for 2010, the 20 % target set for 2020 is binding for all Member States. An effort sharing agreement regulates how much each Member State needs to contribute, with the target depending on the Member State’s current share of renewables, its resource base and its wealth. National targets range from 10 % for Malta up to 49 % for Sweden.

Construction in Sweden slightly below EU-27 average

From: The EU-27 construction sector: from boom to gloom

Construction activities in the EU-27, as recorded by NACE Rev. 1.1 Section F, provided employment to an estimated 14.8 million persons in 2007 (some 11.5 % of the non-financial business economy workforce), while generating an estimated EUR 562 billion of value added (9.3 % of the non-financial business economy’s total value added).

Sweden third among EU-27 in healthy life years at retirement age

From: Healthy life years statistics
Healthy life years (HLY), the number of years that a person is expected to continue to live in a healthy condition, is an important measure of the relative health of populations in the European Union (EU). The HLY indicator is calculated at two ages: birth and the age of 65. The diagram below shows HLY at retirement age.
