The recent economic crisis shaped a new wave of protest in Europe mobilising thousands of people. Austerity measures brought not only the ‘usual suspects’ onto the streets, they also awoke less frequent demonstrators. What brought all these people to the streets? Are their motivations the same for participation in all demonstrations? We compare participants in two types of mobilisations against austerity: those called particularistic (which are reactions to particular anti-austerity issues), and those universalistic (which address much broader issues such as questioning the political system). We also compare two typologies of participants taking into account their participation history: regular and occasional protesters. Employing a two-by-two design defined by type of demonstration (Particularistic vs. Universalistic) and the individual’s participation history (Occasionals vs. Regulars), we found that the differences between demonstrations were smaller than those within types of protesters. Nevertheless, even in this period of hardship, motivation to participate in particularistic or universalistic protests differ depending on the perceptions of political system, ideological positioning and organisational embeddedness. Interaction analyses showed that different levels of identity, trust in institutions and satisfaction with democracy are crucial in driving people to participate in different types of demonstrations as occasionals or regulars. 相似文献

Three-mode analysis is a generalization of principal component analysis to three-mode data. While two-mode data consist of cases that are measured on several variables, three-mode data consist of cases that are measured on several variables at several occasions. As any other statistical technique, the results of three-mode analysis may be influenced by missing data. Three-mode software packages generally use the expectation–maximization (EM) algorithm for dealing with missing data. However, there are situations in which the EM algorithm is expected to break down. Alternatively, multiple imputation may be used for dealing with missing data. In this study we investigated the influence of eight different multiple-imputation methods on the results of three-mode analysis, more specifically, a Tucker2 analysis, and compared the results with those of the EM algorithm. Results of the simulations show that multilevel imputation with the mode with the most levels nested within cases and the mode with the least levels represented as variables gives the best results for a Tucker2 analysis. Thus, this may be a good alternative for the EM algorithm in handling missing data in a Tucker2 analysis. 相似文献

Estimation for the log-logistic and Weibull distributions can be performed by using the equations used for probability plotting, and this technique outperforms the maximum likelihood (ML) estimation often in small samples. This leads to a highly heteroskedastic regression problem. Exact expressions for the variances of the residuals are derived which can be used to perform weighted regression. In large samples, the ML performs best, but it is shown that in smaller samples, the weighted regression outperforms the ML estimation with respect to bias and mean square error. 相似文献

Children in family foster care have the right to participate in decisions regarding their life, however, adults often advocate on behalf of children. This Q methodological study explored whether shared perspectives among foster parents and care workers resemble shared perspectives of youth regarding the psychosocial needs experienced by youth with a history of sexual abuse. Participants sorted a set of statement cards according to what they thought was most important for youth. By-person factor analyses examined how the Q sorts of foster parents and care workers related to those of youth. The results showed that foster parents mostly recognized the group of youth who value an instrumental relationship with their carers, while care workers mostly recognized the group of youth who value support of both foster and birth parents with regard to their preparation for independent living. The two youth groups characterized by ambivalence and autonomy were barely recognized. Results are discussed in light of the expected roles of foster parents and care workers, and youth’s contact with birth parents. Lastly, this study highlights the importance of youth participation, because youth offer unique and varying perspectives about their needs. 相似文献

ABSTRACTThe marriage of children below 18 is widely recognized in international human rights agreements as a discriminatory global practice that hinders the development and well-being of hundreds of millions of girls. Using a new global policy database, we analyze national legislation regarding minimum marriage age, exceptions permitting marriage at earlier ages, and gender disparities in laws. While our longitudinal data indicate improvements in frequencies of countries with legal provisions that prohibit marriage below the age of 18, important gaps remain in eliminating legal exceptions and gender discrimination. 相似文献

A large share of the American population suffers from traumatic experiences early in life. Many adults are also victims of trauma. Using data drawn from the National Comorbidity Survey–Replication, we examine the link between self-reported happiness, a broad gauge of subjective well-being, and four types of traumatic victimization that may occur at various points in the life cycle. In particular, we consider the association between home violence, sexual assault, community violence, and stalking and subsequent victims’ adult happiness. For females and males, we find that each of these traumas significantly reduces self-reported happiness later in the life course, and for both women and men, the estimated impact of home violence is greatest. Furthermore, we find that the adverse effects of trauma on happiness are comparable to the impact of critical socioeconomic developments on happiness. Moreover, we find that experiencing more than one type of these four traumas has a greater negative impact on subsequent happiness than experiencing only one type. Our findings are robust to the inclusion of a wide range of controls, and the influence of trauma on subsequent happiness is independent of personal and family characteristics. Since happiness and mental health are closely related, our work suggests that traumatic victimization undermines overall health and well-being in the U.S. 相似文献

Despite the growing research interest in co-production, some important gaps in our knowledge remain. Current literature is mainly concerned with either the citizens or professionals being involved in co-production, leaving unanswered the question how co-producers and professionals perceive each other’s engagement, and how this is reflected in their collaboration. This study aims to answer that question, conducting an exploratory case study on neighborhood watch schemes in a Dutch municipality. Empirical data are collected through group/individual interviews, participant observations, and document analysis. The results show that the perceptions citizens and professionals hold on their co-production partner’s engagement indeed impact on the collaboration. Moreover, for actual collaboration to occur, citizens and professionals not only need to be engaged but also to make this engagement visible to their co-production partner. The article concludes with a discussion of the practical implications of these findings. 相似文献
