Generating Explanatory Captions for Information Graphics

Graphical presentations can be used to communicate information in relational data sets succinctly and effectively. However, novel graphical presentations about numerous attributes and their relationships are often difficult to understand completely until explained. Automatically generated graphical presentations must therefore either be limited to simple, conventional ones, or risk incomprehensibility. One way of alleviating this problem is to design graphical presentation systems that can work in conjunction with a natural language generator to produce "explanatory captions." This paper presents three strategies for generating explanatory captions to accompany information graphics based on: (1) a representation of the structure of the graphical presentation (2) a framework for identifyingthe perceptual complexity of graphical elements, and (3) the structure of the data expressed in the graphic. We describe an implemented system and illustrate how it is used to generate explanatory cap..

Polar facts in the age of polarization

Many drivers of polar-region change originate in mid-latitude industrial societies, so public perceptions there matter. Building on earlier surveys of US public knowledge and concern, a series of New Hampshire state surveys over 2011–2015 tracked public knowledge of some basic polar facts. Analysis indicates that these facts subjectively fall into two categories: those that are or are not directly connected to beliefs about climate change. Responses to climate-linked factual questions, such as whether Arctic sea ice area has declined compared with 30 years ago, are politicized as if we were asking for climate-change opinions. Political divisions are less apparent with factual questions that do not suggest climate change, such as whether the North Pole is on land or sea ice. Only 38% of respondents could answer that question correctly, and even fewer (30%) knew or guessed correctly that melting of Greenland and Antarctic land ice, rather than Arctic sea ice, could potentially do the most to raise sea levels. At odds with the low levels of factual knowledge, most respondents say they have a moderate amount or a great deal of understanding about climate change. A combination of low knowledge with high self-assessed understanding characterizes almost half our sample and correlates with political views. The low knowledge/high understanding combination is most prevalent among Tea Party supporters, where it reaches 61%. It also occurs often (60%) among people who do not believe climate is changing. These results emphasize that diverse approaches are needed to communicate about science with people having different configurations of certainty and knowledge

Meteorological Input to General Aviation Pilot Training

The meteorological education of general aviation pilots is discussed in terms of the definitions and concepts of learning and good educational procedures. The effectiveness of the metoeorological program in the training of general aviations pilots is questioned. It is suggested that flight instructors provide real experience during low ceilings and visibilities, and that every pilot receiving an instrument rating should experience real instrument flight

Analysis of science textbook pictures about energy and pupils' readings of them

This article outlines the findings of the part of the "Science Teacher Training in an Information Society" (STTIS) project concerned with describing the possible difficulties the pupils have when "reading" science textbook pictures about "energy". Six documents were selected on the basis that they had some of the textual/graphical features previously identified by the project as potentially presenting difficulties to pupils. The pupils' readings of these were investigated using a questionnaire and a follow-up interview. The analysis of three of the documents and of twelve pupils' readings of them is reported in this paper. The results confirm the hypothesis that the "reading" of science textbook pictures is not at all trivial for pupils and conclude that teachers need to spend time and effort talking through the meaning of the images with them. They also suggest that the list of textual/graphical features used in this research is a good starting point for this kind of critical examination

Do You Trust Scientists About the Environment?

In this brief, author Lawrence Hamilton examines the results of a Granite State Poll conducted by the University of New Hampshire Survey Center in late January–early February 2014. The poll asked about public trust in scientists, along with other questions on science, political, and social issues that help to place the science-trust results in perspective. Almost two-thirds of New Hampshire residents surveyed say that they trust scientists to provide accurate information about environmental issues. Only 12 percent do not trust scientists to provide this information. Wide disparities occur along party lines, however, regarding this and other questions about science. The 53 percent gap between Democrats and Republicans on climate change is one of the largest for any issue. Trust in scientists shows a somewhat narrower Democrat–Republican gap (37 percent), which is larger than those for historically divisive social issues such as abortion or the death penalty. Answers to these survey questions also relate to respondents’ news media sources, even after statistical adjustments for political party, age, gender and education. People who often listen to New Hampshire Public Radio are more likely to say they trust scientists, and respond differently from other New Hampshire residents on several other science-related questions. People who often watch local television news or read newspapers, on the other hand, respond differently on questions about the death penalty or gun control
