Information mobility in complex networks
The concept of information mobility in complex networks is introduced on the basis of a stochastic process taking place in the network. The transition matrix for this process represents the probability that the information arising at a given node is transferred to a target one. We use the fractional powers of this transition matrix to investigate the stochastic process at fractional time intervals. The mobility coefficient is then introduced on the basis of the trace of these fractional powers of the stochastic matrix. The fractional time at which a network diffuses 50% of the information contained in its nodes (1/ k50 ) is also introduced. We then show that the scale-free random networks display better spread of information than the non scale-free ones. We study 38 real-world networks and analyze their performance in spreading information from their nodes. We find that some real-world networks perform even better than the scale-free networks with the same average degree and we point out some of the structural parameters that make this possible
Multiple Dimensions of the Moral Majority Platform: Shifting Interest Group Coalitions
The issues raised by the New Political Right and the Moral Majority have overlapped in recent political history. Researchers have assumed that a single additive scale across conservative issues can identify the base of support for the Moral Majority as an organization. We examine general support for the Moral Majority separately from support for six specific issues: teaching creationism, voluntary public school prayer, military defense spending, gun control, pornography and abortion. Data are from a 1982 random sample of adult respondents from Nebraska (N = 1907).
Overall, support for the Moral Majority organization is low. Discriminant analysis identifies fundamentalist and evangelical religious affiliation and Biblical literalism as independent predictors of support for the Moral Majority per se. Education increases knowledge of the organization, but does not influence support for it. Respondents with high income levels are more likely to support the Moral Majority organization. These findings contradict theories of both status politics and cultural fundamentalism.
Support for the six specific platform items also varies considerably and is affected by religious conservatism and, independently, by other attitudinal and demographic indicators including age, sex, income, rural residence, education and perception of declining economic conditions. These patterns do not entirely fit the predictions of status politics or cultural fundamentalism theories. Rather, they provide evidence that distinct coalitions form on specific issues. Our conclusion is that a simple additive index of support for the Moral Majority masks these differences and oversimplifies complex patterns of coalitions in the religio-political arena
The evolution of new party systems: voter learning and electoral systems
How do new party systems evolve over time? This article argues that party system evolution requires the solution of coordination problems that voters face in early elections; this happens through a learning mechanism. Elections reveal information to voters, who update their beliefs about party viability and the distribution of votersâ preferences and adjust their behaviour. The institutional setting, however, strongly conditions the pace of learning. Restrictive electoral systems (single-member district) accelerate learning through the harsh penalties they impose on miscoordination, while permissive ones (proportional representation) prolong it. Testing the argument on a district-level dataset in new democracies provides ample support; voters learn to cast fewer wasted votes over time and this happens faster in single-member district systems. The findings point to a trade-off between consolidation and representation; while party system evolution is facilitated by restrictive electoral systems, the presence of distinct social groups in the political arena is better served by permissive ones
The effects of district magnitude and social diversity on party system fragmentation in majoritarian systems
Cross-national models of party system fragmentation hold that social diversity and district magnitude interact: higher levels of district magnitude allow for greater expression of social diversity that leads to higher levels of party system fragmentation. Most models, however, ignore differences between majoritarian and proportional electoral rules, which may significantly alter the impact of district magnitude, as well as the way in which district magnitude impacts the translation of social cleavages into party system fragmentation. Examining the case of Singapore suggests majoritarian multimember districts limit party system fragmentation, particularly by reducing the degree to which ethnic and religious diversity are translated into political parties. Applying these insights to a standard cross-national model of party system fragmentation, the results suggest that majoritarian multimember districts produce lower levels of party system fragmentation than proportional multimember districts.
Declining partisan representation at the sub-national level: assessing and explaining the strengthening of local lists in Italian municipalities (1995â2014)
In Western democracies political representation at the national level is still dominated by (old and new) political parties. This article shows that, instead, the representative role of parties may have declined at the local level. In Italy, for instance, the average share of municipal seats held by non-partisan councillors has almost tripled in the last 20 years. By using an original data set, this article classifies different types of Italian local lists, assesses their relationship with traditional parties and explains territorial variation in their success. The results suggest that local lists have become substantially stronger in small municipalities, in regions characterised by weak or declining political subcultures and where regionalist parties are absent or irrelevant. Finally, contrary to the expectation that declining partisanship is linked to modernisation processes and direct civic engagement, local lists have achieved their best results in the less developed areas of the country
Aggregation and Representation in the European Parliament Party Groups
While members of the European Parliament are elected in national constituencies, their votes are determined by the aggregation of MEPs in multinational party groups. The uncoordinated aggregation of national party programmes in multinational EP party groups challenges theories of representation based on national parties and parliaments. This article provides a theoretical means of understanding representation by linking the aggregation of dozens of national party programmes in different EP party groups to the aggregation of groups to produce the parliamentary majority needed to enact policies. Drawing on an original data source of national party programmes, the EU Profiler, the article shows that the EP majorities created by aggregating MEP votes in party groups are best explained by cartel theories. These give priority to strengthening the EPâs collective capacity to enact policies rather than voting in accord with the programmes they were nationally elected to represent
The origins of redistributive policy preferences: political socialisation with and without a welfare state
Research on the impact of the macroeconomy on individual-level preferences for redistribution has produced varying results. This paper presents a new theory on the presence of an expansive welfare state during oneâs formative years as a source of heterogeneity in the effect that macroeconomic conditions have on individualsâ preferences for redistributive policy. This theory is tested using cohort analysis via the British Social Attitudes surveys (1983â2010), with generations coming of age between the end of World War I and today. Findings confirm that cohorts that were socialised before and after the introduction of the welfare state react differently to economic crises: the former become less supportive of redistribution, while the latter become more supportive. The research sheds light on the long-term shifts of support for the welfare state due to generational replacement
