Paul Sabatier and Hank Jenkins Smith introduced the Advocacy Coalition Framework (ACF) in the late 1980s, to refine the theoretical and methodological tools available for the study of the policy process. In the past two decades, the framework has grown in use outside the United States, and it is now applied to study a broad range of policy arenas in all continents. ACF scholars have created a core community that regularly synthetizes findings from applications of the framework, giving the ACF the form of a true research program.
The ACF has three principal theoretical domains: advocacy coalitions, policy subsystems, and policy change. Expectations about the interactions between and within these domains are contained in 15 main hypotheses. The ACF posits that advocacy coalitions and policy subsystems are the most efficient way to organize actors interested in the policy process for empirical research. The policy subsystem is the main unit of analysis in the ACF, and there are four paths leading to policy change. The aspect that has received more attention in existing applications is the effect that external events have on policy change, and some areas in need of refinement include: policy-oriented learning, interactions across subsystems, the theoretical foundations to identification of belief systems, and how the interactions between beliefs and interests affect coalition behavior.
International Relations theory has tended to overlook the role of Africa and Africans in the international system. Traditionally, the discipline’s most influential theorists have focused instead on relationships between and perspectives of “major powers.” A growing body of work, however, has challenged these more limited efforts to conceptualize African agency in international politics. This scholarship has emphasized the significant space available to, and carved-out by, African states in molding the agendas of international institutions, and the role of African governments and advocacy networks in influencing the trajectory of major international debates around issues such as aid, development, trade, climate change, and migration. The study of African agency in international politics continues to wrestle with two key debates: the meanings of “agency” and “African.” Much of the literature focuses primarily on the role and influence of African states rather than that of African citizens and communities. This focus provides, at best, only a partial and qualified view of the ways in which African agency is secured and exercised at the global level, particularly given the significant structural constraints imposed on Africa by global economic and political inequalities. The extent to which contemporary analysis captures the breadth of African engagement with the international system is also compromised by current state-centric approaches. It is thus necessary to examine a range of approaches adopted by scholars to deepen and nuance the study of African agency in international politics, including work on agenda-setting, mesolevel dynamics and microlevel dynamics.
There is a great deal of research, spanning social psychology, sociology, and political science, on politically relevant attitudes toward women and the influence of gender on individual’s political decision making. First, there are several measures of attitudes toward women, including measures of sexism and gender role attitudes, such as the Attitudes Toward Women Scale, the Old-Fashioned Sexism Scale, the Modern Sexism Scale, and the Ambivalent Sexism Inventory. There are advantages and disadvantages of these existing measures. Moreover, there are important correlates and consequences of these attitudes. Correlates include education level and the labor force participation of one’s mother or spouse. The consequences of sexist and non-egalitarian gender role attitudes include negative evaluations of female candidates for political office and lower levels of gender equality at the state level. Understanding the sources and effects of attitudes toward women is relevant to public policy and electoral scholars.
Second, gender appears to have a strong effect on shaping men’s and women’s attitudes and political decisions. Gender differences in public opinion consistently arise across several issue areas, and there are consistent gender differences in vote choice and party identification. Various issues produce gender gaps, including the domestic and international use of force, compassion issues such as social welfare spending, equal rights, and government spending more broadly. Women are consistently more liberal on all of these policies. On average, women are more likely than men to vote for a Democratic Party candidate and identify as a Democrat. There is also a great deal of research investigating various origins of these gender differences. Comprehending when and why gender differences in political decision making emerge is important to policymakers, politicians, the political parties, and scholars.

Party membership has long been an important channel for political participation in many countries. Strong membership organizations have helped parties win elections and stay connected with voters between elections, and membership opportunities have helped to mobilize some citizens who might otherwise have stayed out of politics. Yet in the last quarter-century, long-established political parties in parliamentary democracies have, with a few notable exceptions, experienced sharp enrollment declines, while newer parties have developed modest memberships at best. This has led many observers to question the continued viability of membership-based political parties.
However, that is not the whole story. While some signs point to the obsolescence of party membership, there are other indications that parties are trying to reinvent the form, whether as a passport to individual political empowerment or as a pathway to digital citizenship. Most strikingly, many parties are experimenting with new procedures that give members a direct say in important party decisions. In this sense, the paradoxical story of party membership in the early 21st century is one of numerical decline accompanied by a possible increase in political relevance.

Reflecting on the recent rise of Salafi groups and their impact on civil war, the academic literature on Salafi radicalization, mobilization, and recruitment has burgeoned in the recent decade and a half. Yet little consensus exists as to the relative power of three major causes: grievances, ideology, and radical milieu and support structures as causes of violent radicalization. Even less is known about how jihadist foreign fighters affect civil wars in terms of conflict intensity and resolution. In both fields, key debates are identified in the recent scholarship, explain the major shortcomings and gaps, and suggest avenues of future research. For instance, it is important—and hardly avoidable—that epistemological and ontological obstacles lay in the way of establishing the causes of (violent) radicalization, because the processes relating to the change of human perception and behavior are extremely difficult to trace. Another point is the frequent—deliberate or unintended—distortion of the testimonies of former combatants, not least Salafi-jihadists, which makes the task of establishing the causes of (violent) radicalization and recruitment harder. Identifying avenues of further research, there is a lack of quality first-hand data in the current research on Salafi-inspired radicalization, mobilization, and recruitment. More methodological plurality—particularly in-depth ethnographic studies and quantitative work—is needed, as well as more research on virtual social networks and non-verbal contents.

Civil wars typically have been terminated by a variety of means, including military victories, negotiated settlements and ceasefires, and “draws.” Three very different historical trends in the means by which civil wars have ended can be identified for the post–World War II period. A number of explanations have been developed to account for those trends, some of which focus on international factors and others on national or actor-level variables. Efforts to explain why civil wars end as they do are considered important because one of the most contested issues among political scientists who study civil wars is how “best” to end a civil war if the goal is to achieve a stable peace. Several factors have contributed to this debate, among them conflicting results produced by various studies on this topic as well as different understandings of the concepts war termination, civil war resolution, peace-building, and stable peace.
Coalition governments are observed frequently in parliamentary systems. Approximately 70% of all governments in postwar Europe have been one type of coalition or another. Israel has never been ruled by a single-party government in its history. Recently, majoritarian systems like Britain produced coalitions, taking many by surprise.
The prominence of coalitions in parliamentary democracies compels researchers to study them more closely. The Comparative Politics literature investigates, in particular, the dynamics of coalition formation and termination, as well as the domestic policy outputs of coalitions, especially compared to governments ruled by a single party.
Coalitions have generated interest on the International Relations front as well. One avenue of research transcends the “political party” as a building block and conceptualizes coalitions as a “decision unit” by focusing on the group of veto players in a regime’s foreign policy apparatus. Another line of scholarship, situated in the “Democratic Peace” framework, looks at coalitions as a domestic-institutional factor to observe their effects on the likelihood of international conflict.
Departing from the “Democratic Peace” tradition, more recent research in Foreign Policy Analysis rejuvenates the study of coalitions in international politics. This literature not only encourages theory development by scrutinizing why coalitions behave differently than single-parties in the international arena but also bridges the gap between International Relations and Comparative Politics. Emphasizing the organic relationship between domestic politics and foreign policy, foreign policy researchers dissect coalition governments to highlight the role political parties play on foreign policy formulation and implementation. This literature also illustrates the merits of methodological plurality in studying foreign policy. Using a combination of comparative case studies, process tracing, Qualitative Comparative Analysis (QCA) and regression modeling, it sheds light not only on the broader trends that characterize coalition foreign policy but also on the causal mechanisms and contextual factors which often go unaccounted for in purely statistical analyses. The recent advances in role and image theories in Foreign Policy Analysis are expected to influence the study of coalitions and their foreign policies, offering an interpretivist take alongside this positivist trajectory.

Scholars have identified a variety of mechanisms through which religion could impact vote choice in the United States. Researchers have long recognized that, like other social identities, religion is an important factor in the development of party identification. In the United States, evangelical Protestants and highly committed members of other religious traditions tend to favor the Republican Party, while seculars and low-commitment members of other religious traditions tend to favor the Democratic Party. Religion also impacts views on a variety of issues, including abortion, social welfare policy, and foreign affairs. Under the right circumstances, religious voters may incorporate these policy positions into their vote choice. Finally, a growing body of research recognizes that voters use a candidate’s religious views as a heuristic to infer partisanship, ideology, competence, trustworthiness, and a variety of other traits. Given these numerous paths of influence, it is no surprise that researchers regularly find that religion is an important factor in electoral choice.
Researchers have also identified a variety of ways in which religion can impact turnout, thereby creating a second means for religion to influence American elections. Religion helps in the development of social networks and civic skills, thus reducing the costs of political participation. Religion can also be a factor in the development of sociopsychological traits such as threat, thereby facilitating mobilization. By understanding the capacity of religion to impact both turnout and electoral choice, scholars can better understand the myriad ways in which religion influences elections in the United States.

While explicit efforts at gender mainstreaming in foreign policy are relatively recent, a view of foreign policy through a feminist lens illustrates that foreign policy has always been gendered. Feminist scholarship in this area suggests that masculinity has historically shaped foreign policy in important ways, while the increased presence of women in national governments, government cabinets, and the diplomatic corps has produced some notable change in policy outcomes.
An examination of two key concepts related to policymaking and gender—securitization and gender mainstreaming—shows how gender issues have come to the forefront of national and international security agendas since 2000. In particular, the Women, Peace, and Security (WPS) agenda promulgated by the United Nations has obligated individual states to address gendered security issues, and dozens of countries have responded with their own National Action Plans. While these national efforts have led to some improvement in the status of women and related humanitarian outcomes, feminist scholars generally agree that the WPS agenda has stalled in its efforts to produce transformative change. As a way forward, feminist foreign policy stances promise to produce more comprehensive outcomes, though a backlash toward gender mainstreaming and the re-emergence of more traditional security threats has led to questions about the future of such efforts.

The burgeoning field of gender and political behavior shows that the way in which ordinary citizens connect to the democratic process is gendered. Gender differences in voting behavior and participation rates persist across democracies. At the same time, countries vary substantially in the size of these gender gaps. In contemporary elections, women tend to support leftist parties more than men in many countries. Although men and women vote at similar rates today, women still trail men in important participatory attitudes and activities such as political interest and discussion. Inequalities in political involvement undermine the quality of deliberation, representation, and legitimacy in the democratic process. A confluence of several interrelated factors (resources, economy, socialization, political context) work together to account for these differences. Today, scholars more carefully consider the socially constructed nature of gender and the ways in which it interacts with other identities. Recent research on gender and political behavior suggests that political context affects different kinds of women in different ways, and future research should continue to investigate these important interactions.

Religiosity is a combination of public and private religious practices, beliefs, and experiences. While diversity exists in how religiosity is measured, three central components are consistent across the scholarship: organizational religious engagement, non-organizational religious activities, and subjective religiosity. To measure organizational religious engagement, scholars frequently look at church attendance and participation in congregational activities. Non-organizational religious activities include frequency of prayer, reading the Bible or other religious materials, or requesting others to pray for you. Subjective or intrinsic religiosity includes self-assessed religiousness (where respondents are asked, “How religious would you consider yourself?”) or strength of affiliation, as well as specific beliefs, such as views of the afterlife, hell, and whether the Bible is the literal word of God.
Various groups express different levels of religiosity. One of the most well-documented and consistent group-based differences in religiosity is that women, including white women and women of color, are more religious than are men across religions, time, and countries. Women report higher rates of church attendance, engagement in religious practices (including prayer and reading the Bible), and more consistent and higher levels of religious interest, commitment, and engagement. Many explanations for these gaps in religiosity exist including differences in personality and risk aversion, gendered socialization patterns, and patriarchal structures within churches. Scholars have engaged in robust debates around the degree to which explanations like risk assessment or gender role theory can account for differences in religious behavior between men and women. Yet unresolved, these discussions provide opportunities to bring together scholarship and theories from religious studies, sociology, gender studies, psychology, and political science.
Religiosity shapes a variety of important political and social attitudes and behaviors, including political ideology and participation. The effects of religiosity on political attitudes are heterogeneous across men and women—for example, highly religious women and men are not equally conservative, nor do they equally oppose gay rights. The process by which religiosity shapes attitudes is also gendered; for example, the effects of women’s religiosity on political attitudes and participation are mediated by gendered attitudes. And while religiosity increases political participation, the effects are not even for men and women, nor across all groups of women. Future research might examine the differing effects of religiosity on subgroups of men and women, including evaluations of how intersecting social categories like race, gender, and class shape both levels of religious engagement and the degree to which religiosity influences other political and social behavior.

Increased diversity among participants in the justice system, particularly judges, has fueled debates about the values and perspectives that women will bring to the law. Different theories advanced by social psychologists and feminist scholars argue for the premise that men and women in the legal system will approach questions of justice differently. In contrast, empirical scholarship offers only limited support for the expectation that the sex of the judge is related to behavioral outcomes. While most research has not uncovered differences in voting between men and women judges, one area in which consistent differences has been found is in sex discrimination cases.
Recent studies suggest, however, that individual differences between men and women judges may emerge if the focus shifts to the litigation process. In one study of trial courts, cases assigned to women judges were more likely to be settled. In another study of appellate courts, women judges were more likely to pen majority opinions that adopted a compromise position. These findings suggest the promise of shifting the analytical focus away from behavioral outcomes to consider whether, and how, women and men in the legal system shape litigation processes. Doing so will require additional data and triangulated approaches that employ both quantitative and qualitative methods.
Additional research is also needed to explore how shifts in the gender composition of the bench affect organizational norms and practices in the legal system at the federal, state, and local levels. Some work suggests that gender diversity affects deliberations on small appellate panels and consensual norms on larger courts. As the number of women and minorities appointed by recent Democratic and Republican presidents has increased, scholars are also now well positioned to conduct empirical research with larger numbers to investigate how women of color on the bench differ from white women and minority men.

Prior research has found robust support for a relationship between gender inequality and civil war. These results all point in the same direction; countries that display lower levels of gender equality are more likely to become involved in civil conflict, and violence is likely to be even more severe, than in countries where women have a higher status. But what does gender inequality mean in this area of research? And how does research explain why we see this effect on civil war? To explore this, we start with reviewing existing definitions and measurements of gender inequality, noting that the concept has several dimensions. We then proceed to outline several clusters of explanations of how gender inequality could be related to civil war while more equal societies are better able to prevent violent conflict, as described in previous research. It is clear that existing misconceptions that gender inequality primarily involves the role of women are clouding the fact that it clearly speaks to much broader societal developments which play central roles in civil war. We conclude by identifying some remaining lacunas and directions for future research.

It is widely recognized that corruption, or the act of using public power for private ends, is a major destructive force for humans and human societies. Research has shown that corruption is one of the most detrimental factors currently afflicting the economies of developing countries. It further undercuts various dimensions of human well-being such as health, access to clean water, and education, and it negatively affects subjective dimensions of life such as self-reported well-being and happiness.
It was against the backdrop of corruption as a major destructive force that researchers at the World Bank in the late 1990s started to explore new directions in research such as the relevance of the gender perspective. In their groundbreaking study, “Are Women Really the Fairer Sex? Corruption and Women in Government,” Dollar and colleagues demonstrated that higher rates of female participation in government are associated with lower national levels of corruption. They measured corruption using data from the International Country Risk Guide, and they included a broad range of variables in their analysis to control for various underlying institutional characteristics that could be responsible for a spurious correlation. In a follow-up study, Swamy, in 2001, presented a more comprehensive empirical analysis, but most importantly, also a more elaborated theoretical framework. Swamy and colleagues suggested that women may follow laws to a greater extent than men because they feel protected by them. Further, girls may be brought up to have higher levels of self-control than boys, which may prevent them from engaging in criminal acts. For women in power, the most important argument for why an increased number in government would affect corruption was that women might lower corruption levels not only by being less involved in corrupt behavior themselves but also by initiating policies to fight corruption or to recruit staff who are less corrupt.
The initial studies spurred a heated debate on the direction of causality—what effects what—and after more than a decade of research on gender and corruption, it is clear that the link between the two factors is complex: For example, the relationship between levels of women in government and levels of corruption appears in democracies but not in authoritarian states. Moreover, the expected pattern that a high share of women is related to low levels of corruption appears in analysis focusing on the proportion of women in elected assemblies, such as national parliaments, but not in analysis focusing on the proportion of women in the bureaucracy—that is in positions related to the implementation of policies. There is also considerable subnational variation both in levels of corruption and in the share of women in elected assemblies. Studies elaborating on the gender perspective also show the need for reconsidering the definitions of corruption; women are particularly vulnerable in transactions including sexual “services.”
While women have succeeded in promoting a feminist agenda in some parliaments, the international research shows that this is not always possible, and accordingly, not a realistic expectation for women. Parliaments, like any institution, have specific cultural norms and practices, some of which actively work against the advancement of gender equality. Understanding the conditions under which female—and male—parliamentarians might succeed in promoting gender equality outcomes has become an important avenue for research and development practice. The focus on gender-sensitive parliaments allows for a framework to identify, and encourage the development of, those conditions.
There are four key elements of a gender-sensitive parliament. First, it accepts that the responsibility to achieve gender equality, both as a policy outcome and as a process, rests with the parliament as a whole (its male and female members and staff) and with the organizations that drive substantial policy, procedural, and normative development (political parties). Second, a gender-sensitive parliament is guided by institutional policies and legal frameworks, which allow the parliament to monitor its achievements toward gender equality and allow follow-up and review. Third, a gender-sensitive parliament institutionalizes a gender mainstreaming approach through its representational, legislative, and oversight work to ensure that all the parliament’s outputs consider, and counteract, any potential discrimination against women or men, girls or boys. This element requires a reconsideration of the process and structures of the parliament, including the respective roles and capacities of members and parliamentary staff. Fourth, a gender-sensitive parliament constantly strives to eliminate institutional cultures that sanction and perpetuate discriminatory, prejudicial norms and attitudes in the workplace against women members and staff.
Identity has come to figure prominently in the study of foreign policy since the 1990s when it was first introduced by constructivist theorists in International Relations. Consensus on what identity is and what it does in relation to foreign policy does not exist and is unlikely to be ever forged. Some scholars investigate state identity—how it impacts foreign policy processes while simultaneously being impacted by international structures. Others use the concept of identification to examine what foreign policy means for the constitution of modern political subjectivities. Still others seek to bring together constructivist identity scholarship together with more established approaches in Foreign Policy Analysis. This article considers the contextual emergence and evolution of the “identity and foreign policy” scholarship in its many different and differing streams. The large volume of literature produced on this subject over the past two and a half decades defies an easy summary of its theoretical and empirical contributions, but an overview of the main controversies and debates should provide the reader with a solid foundation for further research.

All over the world, indigenous peoples are engaged in domestic and international struggles over their ability to self-determine. Though the specific character and aims of each struggle are different, most resonate with the definition found in the 2007 United Nations Declaration on the Rights of Indigenous Peoples (UNDRIP), which states in article 3 that “Indigenous peoples have the right to self-determination. By virtue of that right they freely determine their political status and freely pursue their economic, social, and cultural development.” The rights extended to “all peoples” under the UN Charter (1945) now explicitly include all indigenous peoples. On the other hand, the right to a State, or what could be called external self-determination, does not seem to follow as article 46, section 1, UNDRIP stipulates that “Nothing in this Declaration may be interpreted as implying for any State, people, group, or person any right to engage in any activity or to perform any act contrary to the Charter of the United Nations or construed as authorizing or encouraging any action which would dismember or impair, totally or in part, the territorial integrity or political unity of sovereign and independent States.” Even singular documents like the UNDRIP highlight the tension that exists between indigenous peoples’ quest for self-determination and national majorities who exercise control over them through the international state system.
The topic of indigenous self-determination is approached from many angles. Legal positivists strive to understand the implications of legal documents like UNDRIP, the International Labour Organization Convention 169, treaties, domestic laws, and, increasingly, sui generis, indigenous law. In debates about the nature, extent, and importance of self-determination, normative political theorists continue to study relationships between territory, citizenship, sovereignty, colonialism, human rights, justice, and institutions including the various legal orders previously mentioned. Increasingly, and combining the legal and normative with the strategic, indigenous scholars have taken the lead in debates that evaluate the strengths and weaknesses of various political approaches in promoting and securing what they believe to be their inherent right to self-determination under difficult circumstances. These range from local cultural revitalization to international indigenous social movements, and often involve evaluating trade-offs between direct action and co-operation with states or between treaty negotiations versus legal actions. In summary, indigenous self-determination is a broad field of study with many approaches, most of which endeavour to understand and ultimately help achieve the emancipation of indigenous peoples from centuries of problematic colonial relations.
Indigenous peoples have become important social and political actors in contemporary Latin America. The politicization of ethnic identities in the region has divided analysts into those who view it as a threat to democratic stability versus those who welcome it as an opportunity to improve the quality of democracy. Throughout much of Latin America’s history, Indigenous peoples’ demands have been oppressed, ignored, and silenced. Latin American states did not just exclude Indigenous peoples’ interests; they were built in opposition to or even against them. The shift to democracy in the 1980s presented Indigenous groups with a dilemma: to participate in elections and submit themselves to the rules of a largely alien political system that had long served as an instrument of their domination or seek a measure of representation through social movements while putting pressure on the political system from the outside. In a handful of countries, most notably Bolivia and Ecuador, Indigenous movements have successfully overcome this tension by forming their own political parties and contesting elections on their own terms. The emergence of Indigenous peoples’ movements and parties has opened up new spaces for collective action and transformed the relationship between Indigenous peoples and the state.
Indigenous movements have reinvigorated Latin America’s democracies. The political exclusion of Indigenous peoples, especially in countries with substantial Indigenous populations, has undoubtedly contributed to the weakness of party systems and the lack of accountability, representation, and responsiveness of democracies in the region. In Bolivia, the election of the country’s first Indigenous president, Evo Morales (2006–present) of the Movement toward Socialism (MAS) party, has resulted in new forms of political participation that are, at least in part, inspired by Indigenous traditions. A principal consequence of the broadening of the democratic process is that Indigenous activists are no longer forced to choose between party politics and social movements. Instead, participatory mechanisms allow civil society actors and their organizations to increasingly become a part of the state. New forms of civil society participation such as Indigenous self-rule broaden and deepen democracy by making it more inclusive and government more responsive and representative. Indigenous political representation is democratizing democracy in the region by pushing the limits of representative democracy in some of the most challenging socio-economic and institutional environments.
In recent decades, the efflorescence of lesbian, gay, bisexual, transgender, and intersex (LGBTI) movements has created powerful inroads for sexual rights in many parts of sub-Saharan Africa. While conditions for LGBTI people vary considerably between and within countries, activists across the region are reshaping political, legal, and social understandings of gender and sexuality through their advocacy, both by seizing opportunities and navigating periods of backlash and repression. Over the years, activists have established domestic movements and have expanded their reach to articulate demands in regional and international forums. Their work has challenged the universality of models developed in other parts of the globe and has generated new tactics to respond to religious, familial, and state-sponsored prejudice. At the same time, questions of representativeness, accountability, and strategy have been raised by constituencies and longtime activists alike, inviting critical assessments of movement politics in the region.

Marriage equality movements have been successful in achieving policy change in an increasing number of states. Hence, a growing body of scholarship has explored institutional and cultural factors that influence activists’ tactics and messaging and, in turn, contribute to marriage equality policy diffusion. Democracies with parliamentary, presidential, and semi-presidential systems, federal and unitary states with varying levels of centralization, and the presence or absence of constitutional anti-discrimination protections provide social movements with divergent political opportunity structures, contributing to dynamics in their tactical choices. In addition, the type of electoral system and party system, the presence of political parties that are movement allies, the use of conscience votes, the level of party discipline, the presence of out LGBT elected officials and straight political allies, and the degree of political will to enact policy change also impact activists’ strategic calculations. Finally, the use of personalized narratives in advocates’ messaging, the framing of marriage equality and LGBT rights as human rights norms, the adoption of family values frames to coopt opponents’ messaging, and the use of homonationalist versus homophobic discourses to justify policymaking decisions regarding same-sex marriage are explored. This article provides a comprehensive review of state-of-the-art research concerning all of the states that have legalized same-sex marriage as well as a detailed analysis of the mechanisms used to achieve policy change. After examining how different explanatory factors perform in accounting for the dynamics in marriage equality activism and policy convergence across a broad range of national contexts, new directions for future scholarship are suggested.
