A lack of clear political commitment together with confusing rules and enforcement often characterize the institutional context of policy implementation and regulatory compliance in developing countries. By connecting such contextual features to existing models of policy implementation and regulatory compliance, we examine how regulatory factors are related to basic and proactive corporate environmental management practices in the Pearl River Delta region in China. Drawing on data derived from both a survey and in‐depth interviews, we show that a perception of clear political commitment to environmental protection across multiple government levels and units is positively associated with business efforts in basic environmental practices, regardless of the specific enforcement intensity. Nevertheless, a perception of clear political commitment is not related to proactive environmental practices. Conversely, a perception of policy ambiguity, in the form of confusing regulatory standards and enforcement, is negatively associated with corporate efforts in both basic and proactive environmental practices; yet, intensive inspections mitigate these negative associations with policy ambiguity.  相似文献

Policy advocacy is an increasingly important function for many nonprofit organizations, yet their advocacy activities have largely escaped theoretical grounding. The literature on nonprofits has described how they engage in policy advocacy, without linking them to theories of policy change. The policy studies literature, on the other hand, has explained how various forms of influence result in policy change, but has largely ignored organizational perspectives on those processes. These two literatures remain largely disconnected. Drawing upon interviews with a purposive sample of policy advocacy directors at 31 nonprofit organizations, this study applies Q‐methodology to identify and describe six distinct policy advocacy strategies employed by the organizations, and their resonant theoretical views of policy processes. These findings suggest strategic approaches for nonprofits seeking to influence policy processes. They also enhance the academic literature on policy processes by adding the advocates’ views and expectations. Implications for further research are also identified.  相似文献

In this paper, I present an intensive case study of the development of the National Flood Insurance Program to advance two key arguments. First, the conventional model of adoption of general interest reform neglects an important aspect of political context: whether the relevant policy domain is one with or without “publics.” I argue that in domains without publics the politics of reform will differ substantially from the accepted model. Second, I argue that the type of learning necessary to address a given policy failure matters in reform politics. Instrumental learning is necessary but may not be sufficient for successful general interest reforms. When the social construction of a policy failure is such that many people misconceive of the fundamental purpose of a policy, social learning must take place before instrumental learning can be effective.  相似文献

Epistemic communities are an established concept in the study of international relations but can also explain policy change at the domestic level. This article asks why some epistemic communities manage to convince decision makers of their preferred policies while others do not. It suggests that the reason lies in the causal mechanism of epistemic communities' influence on decision makers, mediated by decision makers' demand for expert input. Most epistemic communities scholarship focuses on single case studies where the communities' influence on policy was strong and clear, leading to an overestimation of the groups' influence. To help correct this probable bias, this article compares a successful case of epistemic community influence (health technology assessment in Poland) with an unsuccessful example of the same policy (in the Czech Republic). The juxtaposition allows for unpacking of the necessary parts of the causal mechanism (emergence of an epistemic community, its activity, access to decision makers, and successful suasion) and separating them from the crucial scope condition. Decision makers' uncertainty about the policy issue at hand has traditionally been the key scope condition for epistemic communities but the successful Polish case demonstrates that epistemic communities can be influential even in highly certain areas of routine policymaking, leading to a reconceptualization of uncertainty as policymakers' demand for expert input. Demand can originate from various sources, but any change of it affects individual parts of the causal mechanism, leading to a success or failure of epistemic communities' policy enterprise.  相似文献

Since the devolution of welfare policymaking to the states after the passage of the 1996 Personal Responsibility and Work Opportunity Reconciliation Act, there has been contentious debate about drug testing welfare applicants. Beyond elite rhetoric and debate points about the implications of welfare drug testing, extant research remains limited insofar as providing theoretical understanding about what factors influence state proposal of legislation requiring welfare applicants to submit to drug tests. I develop and test expectations that derive from research on welfare attitudes, social construction theory, and policy design—specifically, hypotheses that the proportion of blacks on state temporary assistance for needy families caseloads, as well as state‐aggregate levels of symbolic racism, significantly influence state proposal of drug testing legislation. My multilevel analysis of every state proposal of welfare drug testing legislation from 2008 to 2014 yields strong evidence in support of these hypotheses and paints a more complete picture of the influence of racial attitudes on state welfare policymaking. Specifically, while much research finds evidence of institutional racial biases in the implementation of welfare policy, the evidence presented herein shows that these biases, as well as public biases, influence policymaking at the proposal stage. Implications of these findings are discussed in light of recent significant electoral gains made by Republicans in state legislatures.  相似文献

Scholars of Canadian politics have noted that the Prime Minister plays a dominant role in shaping domestic and foreign policy. This article examines the role of the Prime Minister in shaping Canadian foreign policy toward Israel since 1993 and shows the central role that the Prime Minister has played on this issue. It specifically argues that Stephen Harper produced a noticeable pro-Israel shift in Canada’s policy and moved Canada away from the multilateralist approach pursued by Jean Chrétien and, to a lesser extent, Paul Martin. But this article also argues that Justin Trudeau has so far embraced a policy that largely reinforces the approach of Harper rather than rejecting it. Thus, one practical implication of the dominant role of the Prime Minister in shaping Canada’s policy toward Israel is that Canada has become more one-sided in its support of Israel in the past two decades.  相似文献

The liberalisation of the White Australia policy in the mid-1960s was a seminal event in Australian history. It marked the beginning of the end for the racial conception of society which had defined the federation since the late-nineteenth century. Cabinet’s discussions of the proposed changes during these years demonstrate that most Australian political leaders were not only fundamentally opposed to reform but also unconvinced by arguments emphasising the policy’s administrative inconsistencies, lack of humanitarianism and racially discriminatory features. Nor were they entirely swayed by arguments of diplomatic expediency, which had been advanced by senior Immigration and External Affairs officials since the 1950s. The decline of British race patriotism in the early 1960s weakened the ideological foundations of White Australia and allowed policy-makers to reconsider its foreign policy implications, especially in terms of Australia’s relations with Asia. Although cautious, the reforms of the mid-1960s represented an important break with the policy’s fundamental principles and provided the groundwork for further liberalisation and the formal abolition of White Australia in the 1970s.  相似文献

ABSTRACT

Attending to Poly-Olbion’s river dynamics, I argue that, implicitly opposing natural, inevitable unionization, Drayton demonstrates through visual and poetic means that any viable empire is forged by deliberate local choices about conjunction and affiliation. Further, I show that by reconfiguring Saxton’s maps, rejecting politically defined boundaries and perceptions, and situating three major rivers as the organizing features of the landscape and the empire, Drayton ultimately defines Britain as inherently and universally maritime. Moreover, linking Poly-Olbion to mare clausum and mare liberum debates, I reveal that Drayton situates the flow of self-aware rivers into the sea as an extension of Britain beyond its land boundaries. He thereby suggests that the eventual mixing of British waters with the larger oceans establishes the basis of Britain’s local and global maritime rights, linking regional autonomy and conjunction by choice with claims to both local offshore dominion and global freedom of navigation and trade.  相似文献

Smoking bans have recently expanded to private vehicles in which children are present. This study considers the place of children's rights and children's voices in this policy initiative, with respect to the Canadian context, where vehicular smoking bans have been widely adopted. First, we examine print media reports, finding children's right to health was acknowledged less frequently than an array of competing adult rights. Children's voices were largely absent from the record. Second, we report on focus groups involving 23 young people in Edmonton, Alberta, highlighting participants' strong support for bans, based on their knowledge of health harms, aversion to smoke, and awareness that children have limited ability to contest adult authority in vehicles. We conclude that vehicular smoking bans may address the situation whereby children are forced to share an unhealthy environment, in breach of their rights.  相似文献

1971年印巴危机是冷战时代一次具有重大国际影响的地区危机。危机期间,因受东巴内战与印巴冲突的双重影响,大量东巴居民逃往印度,沦为难民。东巴难民持续涌入印度不仅是东巴危机转变为印巴危机的主要诱因,同时也是导致南亚持续紧张、敌对氛围难以消解的重要根源。为妥善解决难民问题,美国积极谋划,投入大量人力、物力、财力,意图妥善解决难民问题,化解危机。但是美国采取的积极措施并未减缓危机冲突的不断升级。在处理难民问题的过程中,美巴政策协调趋于一致,而印度与美巴在难民问题上的政策倾向却渐行渐远。归根究底,是否应该在难民问题上附加最终促成东巴独立的政治条件是美巴与印度的根本分歧所在。而这一根本分歧的悬而未决最终成为引爆第三次印巴战争的导火索。  相似文献
