A visual language to characterise transitions in narrative visualization

We use a taxonomy of panel-to-panel transitions in comics, refined the definition of its components to reflect the nature of data-stories in information visualization, and then, use the taxonomy in coding a number of VAST challenges videos from the last four years. We represent the use of transitions in each video graphically with a diagram that shows how the information was added incrementally in order to tell a story that answers a particular question. A number of issues have been taken into account when coding transitions in each video as well as in designing and creating the visual diagram such as, nested transitions, the use of sub-topics, and delayed transitions

Effects of candidate position on ballot papers: Exploratory visualization of voter choice in the London local council elections 2010

The relationship between candidates’ position on a ballot paper and vote rank is explored in the case of London local council elections. A design study uses information visualization techniques to identify patterns and generate hypotheses. Using clustered bar-charts and spatial treemaps, the effects of ballot ordering are shown. Visual evidence is presented to suggest that the order of placement of the names of candidates acts to bias voters towards those whose names are towards the top of the ballot paper. The findings of this research have significant implications for the design of ballot papers and the conduct of fair elections

The effect of information visualization delivery on narrative construction and development

We conducted a within-subject experiment involving 13 participants that empirically explore how two different models of story delivery involving information visualization influence audience-constructed narratives. The first model involves a speaker using visualization software to communicate a direct narrative, while the second involves constructing a story by interactively exploring visualization software. We used an openended questionnaire in controlled laboratory settings, with the primary goal of collecting a number of stories derived from the two models, followed by two Likert-scale questions on the ease of telling and curiosity about the story in each delivery model. We qualitatively analysed the stories constructed by the participants, based on a number of themes tied to storytelling, including time and place and narrative structure. The study’s results reveal some interesting possible differences in how users receive, interpret, and create stories in each case

A cross-cultural study into peer evaluations of women\u27s leadership effectiveness

Purpose: The present paper is based on a cross-cultural exploration of middle managers in two diverse cultures and aims to focus on how the leadership styles of managerial women are perceived and evaluated. In particular, female and male peer evaluations of leadership effectiveness in Malaysia and Australia are to be explored.Design/methodology/approach: Surveys from 324 middle managers from Malaysia and Australia were quantitatively analysed. The sample for the study was drawn from organisations in four industry types in both countries.Findings:&nbsp; Findings suggest that evaluations of female managers\u27 leadership styles in general, and within the respondent\u27s own organisations, were strongly culture specific, especially in Malaysia. The results reflected the strongly held values, attitudes and beliefs of each country. While this is not unexpected, it does highlight a need to be cautious when interpreting Western research results and attempting to transplant those into other cultures. In Malaysia, female managers were not seen as effective in the leadership styles they adopted in their roles when compared to the Australian female managers\u27 evaluations. Such an evaluation may have had little to do with an objective appraisal of the female managers\u27 capability, but rather with a strongly held cultural belief about the appropriate role of women in society, and in organisations in particular.Research limitations/implications:&nbsp; It is suggested that national culture manifests itself in the values, attitudes and behaviours of people. Cultural influences are therefore likely to impact on the way women and men behave in the workplace, particularly when roles of authority and power are evident, and the way in which that behaviour will be evaluated by others. Further research using different samples in different cultures are recommended. In addition, the influence of ethnicity, race or religion in plural countries such as Malaysia and Australia is also worthy of investigation.Practical implications:&nbsp; This research suggests that values and attitudes are strongly culture-specific and therefore have the ability to influence evaluations at an organisational level. Such an awareness of cultural influences should guide appropriate human resource practices, particularly within a globalized environment.Originality/value:&nbsp; The inclusion of a gender comparison in the data analysis in this paper is a significant attempt to add to the extant knowledge of the cross-cultural research. This is a unique contribution because of the omission of a gender perspective in the previous two seminal studies in culture literature (i.e. Hofstede and House et al.). In addition, the findings suggest that culture-specific influences are important determinants that impose expectations on the role of women differently from men in society and within organisations hence, making the gender comparison of the findings more significant. <br /

Malaysian and Australian male and female middle managers : a cross-cultural comparison of workplace attitudes, aspirations for promotion, and self-rated leadership styles

This paper outlines the rise of women in management worldwide, and considers why so few women achieve senior or executive management positions. This slow advance of women into senior roles is unexpected given that the changes in organisations today are believed to require more &lsquo;feminine leadership&rsquo;. A decrease in the emphasis on masculine characteristics for managers is reported, and a requirement that more &lsquo;feminine leadership&rsquo; needs to be adopted by organisations in order to ensure their survival in the future (Powell, Butterfield &amp; Parent, 2002, p.189). Recent empirical research reports that there are differences in leadership style between male and female managers, and the findings suggest that women exhibit more transformational leadership than their male counterparts, with this style being strongly equated with effective leadership (Eagly, Johannesen-Schmidt, van Engen, 2003). However, these findings are based on western research, and it may be that cross cultural research will yield a different picture (House, Hanges, Javidan, Dorfman, &amp; Gupta, 2004). Leadership and leadership styles may be conceptualised differently in a more paternalistic society. To explore this possibility, a cross cultural study was conducted in Malaysia and Australia. It is hypothesised that countries that are paternalistic in cultural values will exhibit a stronger constraint on women in management roles, which may impact on workplace attitudes, aspirations for promotion and style of leadership exhibited. Therefore, it is possible that the career advancement of women may be more problematic for Malaysian managerial women than their Australian counterparts. Results from an initial pilot study in Malaysia and Australia are outlined, and highlight some interesting similarities and differences to what are reported in the western literature.<br /

Radial Velocity Curves of Ellipsoidal Red Giant Binaries in the Large Magellanic Cloud

Ellipsoidal red giant binaries are close binary systems where an unseen, relatively close companion distorts the red giant, leading to light variations as the red giant moves around its orbit. These binaries are likely to be the immediate evolutionary precursors of close binary planetary nebula and post-asymptotic giant branch and post-red giant branch stars. Due to the MACHO and OGLE photometric monitoring projects, the light variability nature of these ellipsoidal variables has been well studied. However, due to the lack of radial velocity curves, the nature of their masses, separations, and other orbital details has so far remained largely unknown. In order to improve this situation, we have carried out spectral monitoring observations of a large sample of 80 ellipsoidal variables in the Large Magellanic Cloud and we have derived radial velocity curves. At least 12 radial velocity points with good quality were obtained for most of the ellipsoidal variables. The radial velocity data are provided with this paper. Combining the photometric and radial velocity data, we present some statistical results related to the binary properties of these ellipsoidal variables.Comment: 10 pages, 8 figures, 3 table

Equity of access to adult hospice inpatient care within north-west England.

There is a growing debate about the question of equity of access to hospice and palliative care services. Even countries with relatively well developed palliative care systems are considered to have problems of access and inequity of provision. Despite these concerns, we still lack a relevant evidence base to serve as a guide to action. We present an analysis of access to adult hospice inpatient provision in the north-west region of England that employs Geographical Information Systems (GIS). Measures of the possible demand for, and supply of, hospice inpatient services are used to determine the potential accessibility of cancer patients, assessed at the level of small areas (electoral wards). Further, the use of deprivation scores permits an analysis of the equity of access to adult inpatient hospice care, leading to the identification of areas where additional service provision may be warranted. Our research is subject to a number of caveats�it is limited to inpatient hospice provision and does not include other kinds of inpatient and community-based palliative care services. Likewise, we recognise that not everyone with cancer will require palliative care and also that palliative care needs exist among those with nonmalignant conditions. Nevertheless, our methodology is one that can also be applied more generally

Rectangular Hierarchical Cartograms for Socio-Economic Data

We present rectangular hierarchical cartograms for mapping socio-economic data. These density-normalising cartograms size spatial units by population, increasing the ease with which data for densely populated areas can be visually resolved compared to more conventional cartographic projections. Their hierarchical nature enables the study of spatial granularity in spatial hierarchies, hierarchical categorical data and multivariate data through false hierarchies. They are space-filling representations that make efficient use of space and their rectangular nature (which aims to be as square as possible) improves the ability to compare the sizes (therefore population) of geographical units. We demonstrate these cartograms by mapping the Office for National Statistics Output Area Classification (OAC) by unit postcode (1.52 million in Great Britain) through the postcode hierarchy, using these to explore spatial variation. We provide rich and detailed spatial summaries of socio-economic characteristics of population as types of treemap, exploring the effects of reconfiguring them to study spatial and non-spatial aspects of the OAC classification

Non-positivity of the Wigner function and bounds on associated integrals

The Wigner function shares several properties with classical distribution functions on phase space, but is not positive-definite. The integral of the Wigner function over a given region of phase space can therefore lie outside the interval [0,1]. The problem of finding best-possible upper and lower bounds for a given region is the problem of finding the greatest and least eigenvalues of an associated Hermitian operator. Exactly solvable examples are described, and possible extensions are indicated.Comment: 5 pages, Latex2e fil

BallotMaps: Detecting name bias in alphabetically ordered ballot papers

The relationship between candidates’ position on a ballot paper and vote rank is explored in the case of 5000 candidates for the UK 2010 local government elections in the Greater London area. This design study uses hierarchical spatially arranged graphics to represent two locations that affect candidates at very different scales: the geographical areas for which they seek election and the spatial location of their names on the ballot paper. This approach allows the effect of position bias to be assessed; that is, the degree to which the position of a candidate’s name on the ballot paper influences the number of votes received by the candidate, and whether this varies geographically. Results show that position bias was significant enough to influence rank order of candidates, and in the case of many marginal electoral wards, to influence who was elected to government. Position bias was observed most strongly for Liberal Democrat candidates but present for all major political parties. Visual analysis of classification of candidate names by ethnicity suggests that this too had an effect on votes received by candidates, in some cases overcoming alphabetic name bias. The results found contradict some earlier research suggesting that alphabetic name bias was not sufficiently significant to affect electoral outcome and add new evidence for the geographic and ethnicity influences on voting behaviour. The visual approach proposed here can be applied to a wider range of electoral data and the patterns identified and hypotheses derived from them could have significant implications for the design of ballot papers and the conduct of fair elections
