It is often said that parliament shouldrepresent the opinions found in thepopulation and that government should beheld accountable for its political program.It is shown that these two goals rely ontwo different basic models of democracywhich are not fully compatible with eachother: the model of a pure representativedemocracy and the model of a pure two partycompetition. Unaccountable governments,voter alienation, strategic voting, andgovernmental instability are shown to beconsequences of this institutional mix.These problems may be avoided with reformsin the direction of one or the other basicmodel.  相似文献

Entrepreneurship represents a form of adaptive developmental regulation through which both entrepreneurs and their ecologies benefit. We describe entrepreneurship from the perspective of relational developmental systems theory, and examine the joint role of personal attributes, contextual attributes, and characteristics of person-context relationships in predicting entrepreneurial intent in a sample 3,461 college students enrolled in colleges and universities in the United States (60 % female; 61 % European American). Specifically, we tested whether personal characteristics (i.e., gender, intentional self-regulation skills, innovation orientation) and contextual factors (i.e., entrepreneurial parents) predicted college students’ intentions to pursue an entrepreneurial career. Our findings suggest that self-regulation, innovation orientation, and having entrepreneurial role models (i.e., parents) predict entrepreneurial intent. Limitations and future directions for the study of youth entrepreneurship are discussed.  相似文献

This paper analyzes the consequences of different assumptions regardingthe kind of uncertainty that exists at the constitutional stage of a two-stage political process. Individuals at the constitutional stagedecide the actions that are to be allowed, compelled or banned in thesubsequent stage. The analysis allows us to specify conditions under whichcertain bans and obligations might be included in a constitution, whileothers are decided by legislative action, to define the ``optimal votingrule'', and the conditions under which the majority rule is this optimalrule. The paper provides a unified framework for analyzing the choice ofinstitutions in a two-stage constitutional political system.  相似文献

Prior research has demonstrated that participation in out-of-school time activities is associated with positive and healthy development among adolescents. However, fewer studies have examined how trajectories of participation across multiple activities can impact developmental outcomes. Using data from Wave 3 (approximately Grade 7) through Wave 8 (approximately Grade 12) of the 4-H Study of Positive Youth Development, this study examined patterns of breadth in out-of-school time participation in activities and associated outcomes in positive youth development (PYD), Contribution to self and community, risk behaviors, and depressive symptoms. We assessed 927 students (on average across waves, 65.4 % female) from a relatively racially and ethnically homogeneous sample (about 74 % European American, across waves) with a mean age in Wave 3 of 12.98 years (SD = 0.52). The results indicated that high likelihood of participation in activities was consistently associated with fewer negative outcomes and higher scores on PYD and Contribution, as compared to low likelihood of participation in activities. Changes in the breadth of participation (in particular, moving from a high to a low likelihood of participation) were associated with increased substance use, depressive symptoms, and risk behaviors. Limitations of the current study, implications for future research, and applications to youth programs are discussed.  相似文献
