Party identification is a central concept in studies of parties and elections. Drawing from an extensive literature linking the concept of party identification to the understanding of Mexico's electoral politics, this article explores how the Mexican experience informs the understanding of party identification in general, especially in emerging democracies. There, voters' attachments to political parties are usually seen both as essential to and a positive sign of democratic development. This study finds evidence consistent with these arguments in the Mexican case but also identifies aspects of Mexican party identification that are not so clearly supportive of democratic politics; that indeed may delay or even undermine democratization. These findings illustrate the relevance of the Mexican experience to the wider literature on parties and elections, particularly the well-documented relationship between party identifications and democratization. 相似文献

It is unknown whether perceived pubertal timing changes as puberty progresses or whether it is an important component of adolescent identity formation that is fixed early in pubertal development. The purpose of this study is to examine the stability of perceived pubertal timing among a school-based sample of rural adolescents aged 11-17 (N=6,425; 50% female; 53% White). Two measures of pubertal timing were used, stage-normative, based on the Pubertal Development Scale, a self-report scale of secondary sexual characteristics, and peer-normative, a one-item measure of perceived pubertal timing. Two longitudinal methods were used: one-way random effects ANOVA models and latent class analysis. When calculating intraclass correlation coefficients using the one-way random effects ANOVA models, which is based on the average reliability from one time point to the next, both measures had similar, but poor, stability. In contrast, latent class analysis, which looks at the longitudinal response pattern of each individual and treats deviation from that pattern as measurement error, showed three stable and distinct response patterns for both measures: always early, always on-time, and always late. Study results suggest instability in perceived pubertal timing from one age to the next, but this instability is likely due to measurement error. Thus, it may be necessary to take into account the longitudinal pattern of perceived pubertal timing across adolescence rather than measuring perceived pubertal timing at one point in time. 相似文献

A major question for public managers is whether municipal services should be rendered in-house or contracted out. In view of the negative perceptions often aroused by contracting out, this political decision might be framed within a theoretical model that we term ‘dynamic-opportunistic behaviour’. According to this model, the probability of municipal services being contracted out is greater in the years immediately following elections; moreover, during this period the decision is taken more quickly. In this theoretical model, not all factors (budgetary, economic, political, service characteristics and socio-economic) have an equal impact on the contracting-out decision during each year of the electoral cycle. The model was applied to a sample of 2,274 Spanish municipalities, with respect to a broad time horizon (2002–2014), and the results obtained confirm our hypotheses regarding dynamic-opportunistic behaviour in the contracting out of local public services. 相似文献

Inverse Productivity or Inverse Efficiency? Evidence from Mexico 总被引:2,自引:0,他引:2
Using a unique panel data set from rural Mexico, we find strong evidence of a negative relationship between farm size and both productivity and technical efficiency: large farms not only have a lower value of output per hectare than small farms, they also produce further from the efficiency frontier. Our findings suggest that, in spite of the ongoing transformation of agricultural supply chains and economists’ recommendations for small farmers to exit crop production, there may be sustained advantages for smallholder farms. Our analysis offers new insights into inverse-farm size relationship, the productivity–efficiency relationship, and the use of stochastic frontier techniques. 相似文献

The functioning and composition of the Spanish Intelligence Community is not regulated in detail by any legal regulations, and neither the intelligence service nor the government have specified these despite the repeated references they make to them. This article sets out to establish what actually constitutes the Intelligence Community in Spain; thus, after a brief theoretical discussion in which the two major categories of members – consumers and producers – are identified, a model of the intelligence community in Spain is set forth on the basis of the interrelations between its members and their roles in the decision-making process. In its preparation, besides analyzing the existing legislation, 52 interviews were carried out with individual participants in all the structures, so as to reach an understanding of the role played by each one, to evaluate its performance and to propose some guidelines for improvement. 相似文献
