Using methods and themes from Charles Tilly’s work, this paper presents a number of propositions related to empire-to-state transformation. We argue that variations in national state development from imperial metropole origins can be explained, at least in part, by variations in imperial administration, finance, development, identity, and inequality. Capacity is a critical determinant of the results of state transformation, while decisions about finance and investment are both economic and political. Identity and inequality are inextricably linked to empire, and our exploration of these concepts demonstrates that they are the outcomes of variable processes linked to concrete, if inadvertent, lines of imperial decisions.  相似文献

The aim of this study was to investigate the association between social support, loneliness and well-being from a multidimensional perspective for which two structural models are proposed. The study included 2042 participants from Malaga City (Spain) who were aged between 18 and 95 years. For the dimensions frequency of support and satisfaction with support, the results show that partner support, family support, and support from friends, respectively, significantly decrease romantic loneliness, family loneliness, and social loneliness. On the other hand, community support has little effect on reducing social loneliness. Of the three types of support analyzed (emotional, informational and instrumental), emotional support was significantly more effective in reducing loneliness (family, romantic and social) and increasing well-being. Loneliness partially acts as a mediator variable, although it is affected by social support, but at the same time decreases the effects of social support on subjective well-being. The three types of loneliness have a strong negative impact on subjective well-being. Implications of these results are discussed.  相似文献

Abstract

The use of information technology (IT) is growing; access and use differ among those from different races, ethnicities, income and education levels, jobs, ages, and genders. Although some argue that broadband technology could be the platform for universal access, the benefits are still debatable for municipalities providing access. The authors discuss how public officials have decided to lead, support, and usher in an era of rapid IT development through wireless broadband networks to address digital divide concerns, and how these claims may meet—or fail to meet—expectations. The purpose of this paper is twofold: (1) to propose a fruitful investigative overview of U.S. cities claiming that a municipal wireless network will bridge the “digital divide”; and (2) to employ discourse analysis to examine the digital divide language 24 municipal wireless networks (MWNs) use.  相似文献

We present estimates of the private and fiscal returns to schooling in 14 European Union countries. Estimates of the private returns to post‐compulsory formal education take into account the effects of schooling on wages and employment probabilities and allow for academic failure rates, the direct and opportunity costs of education, and the impact of personal taxes, social security contributions, and unemployment and pension benefits on lifetime earnings. Estimates of fiscal returns capture the long‐term effects of a marginal increase in average educational attainment on public finances under conditions that approximate general equilibrium.

We introduce an exponential neighborhood for the Vehicle Routing Problem (vrp) with unit customers’ demands, and we show that it can be explored efficiently in polynomial time by reducing its exploration to a particular case of the Restricted Complete Matching (rcm) problem that we prove to be polynomial time solvable using flow techniques. Furthermore, we show that in the general case with non-unit customers’ demands the exploration of the neighborhood becomes an -hard problem.  相似文献

Using matched employer–employee data from the Spanish labour market in 2010, we analyse the effects of industrial, establishment and occupational segregation on the gender wage differential, disaggregating the latter contribution by different groups of workers belonging to different occupational areas and responsibility levels. These workers are employed in 61 occupations within 26,492 establishments in 51 different industries. Since the matched employer–employee data exhibit a particular type of grouped structure, which contrasts the statistical properties of such data with the random sample case, we estimate the effects of each type of gender segregation on the wage gap using a robust specification. We find that the major part of the contribution of gender segregation is not explained by differences in the observable characteristics. Furthermore, the estimations show that the educational female advantage has helped to narrow the gender wage gap caused by occupational segregation within each establishment only for those groups of workers with the lowest educational requirements.  相似文献

Abstract

Although many manual operations have been replaced by automation in the manufacturing domain in various industries, skilled operators still carry out critical manual tasks such as final assembly. The business case for automation in these areas is difficult to justify due to increased complexity and costs arising out of process variabilities associated with those tasks. The lack of understanding of process variability in automation design means that industrial automation often does not realize the full benefits at the first attempt, resulting in the need to spend additional resource and time, to fully realize the potential. This article describes a taxonomy of variability when considering the automation of manufacturing processes. Three industrial case studies were analyzed to develop the proposed taxonomy. The results obtained from the taxonomy are discussed with a further case study to demonstrate its value in supporting automation decision-making.  相似文献

Influence diagnostics in Gaussian spatial linear models   总被引:2,自引:0,他引:2  
Spatial linear models have been applied in numerous fields such as agriculture, geoscience and environmental sciences, among many others. Spatial dependence structure modelling, using a geostatistical approach, is an indispensable tool to estimate the parameters that define this structure. However, this estimation may be greatly affected by the presence of atypical observations in the sampled data. The purpose of this paper is to use diagnostic techniques to assess the sensitivity of the maximum-likelihood estimators, covariance functions and linear predictor to small perturbations in the data and/or the spatial linear model assumptions. The methodology is illustrated with two real data sets. The results allowed us to conclude that the presence of atypical values in the sample data have a strong influence on thematic maps, changing the spatial dependence structure.  相似文献

Objective. This study aims to provide a better understanding of how beliefs about the system of social mobility affect students' schooling outcomes. Previous studies reach conflicting conclusions because they conflate two forms of beliefs about social mobility (i.e., perceived value of school and perceived barriers despite schooling). Methods. The Maryland Adolescence Development In Context Study (MADICS) is used to examine black‐white differences in beliefs about the value of school and barriers to upward mobility despite schooling and how these beliefs predict academic achievement and educational attainment. Results. The analyses show that relative to whites, blacks hold stronger beliefs in both the value of school and barriers to social mobility, and have greater affective attitudes toward schooling. However, belief in barriers to social mobility is not consequential for academic outcomes. Conclusions. Beliefs about upward mobility are mechanisms by which the opportunity structure influences individuals' schooling behaviors and making clear distinctions between various beliefs about the system of social mobility can refine the understanding of this link. This study suggests that individuals make nuanced distinctions about the role of schooling for upward mobility, each with separate effects on academic outcomes.  相似文献

This study examined the perceived parental styles of maternal warmth and control, as well as adolescent filial piety, in relation to parent–child relationship quality, in 308 Hong Kong Chinese adolescents. The three mother–child relationship qualities measured were perceived maternal support, conflicts, and relationship depth. Adolescents' attitudes toward filial piety explained unique variance in all three of these parent–child relational qualities, over the constructs of maternal warmth and control. In addition, the interaction of filial piety with maternal control explained unique variance in perceived maternal support and mother–child conflicts, but not relationship depth. Results established the potential unique importance of adolescent filial piety and confirmed our hypothesis that the more adolescents emphasize filial piety, the more parental control exerts a positive effect on mother–child relationship quality in Hong Kong families.  相似文献
