Hydrosocial spatio-temporalities—aspects of water belonging to space, time, or space-time—are central to water governance, providing a framework upon which overall hydrosocial relations are constructed, and are fundamental to the establishment of values and central to socio-cultural-political relationships. Moreover, spatio-temporal conceptions may differ among diverse governing entities and across scales, creating “variability” through ontological pluralism, as well as power asymmetries embedded in cultural bias. This paper explores spatio-temporal conceptions related to water quality governance, an aspect of water governance often biased toward technical and scientific space-time conceptions. We offer examples of different aspects of spatio-temporality in water quality issues among Tribes in the United States, highlighting several themes, including spatiotemporal cycles, technological mediation, and interrelationship and fluidity. Finally, we suggest that because water is part of a dynamic network of space-times, water quality may be best governed through more holistic practices that recognize tribal sovereignty and hydrosocial variability.

Retrospective voting is a crucial component of democratic accountability. A large literature on retrospective voting in the United States finds that the president’s party is rewarded in presidential elections for strong economic performance and punished for weak performance. By contrast, there is no clear consensus about whether politicians are held accountable for the local economy at other levels of government, nor how voters react to the economy in a complex system of multilevel responsibility. In this study, we use administrative data on county-level economic conditions from 1969 to 2018 and election results across multiple levels of government to examine the effect of the local economy on elections for local, state, and federal offices in the United States. We find that the president’s party is held accountable for economic performance across nearly all levels of government. We also find that incumbents are held accountable for the economy in U.S. House and gubernatorial elections. Our findings have broad implications for literatures on representation, accountability, and elections.

Federalism refers to the constitutional and political structure of the United States of America, according to which political power is divided among multiple levels of government: the national level of government (also referred to as the “federal” or “general” government) and that of the states. It is a multilayered system of government that reserves some powers to component entities while also establishing an overarching level of government with a specified domain of authority. The structures of federalism are set forth in the Constitution of the United States, although some related ideas and practices predated the founding period and others have developed since. The balance between federal and state power has shifted throughout U.S. history, with assertions of broad national power meeting challenges from supporters of states’ rights and state sovereignty. Federalism is a fundamental value of the American political system, and it has been a controversial political and legal question since the founding period.

How can we enhance theory-method alignment when studying collective leadership? We propose that leveraging methodological approaches that are powerful enough to address three primary challenges of collective leadership—the incorporation of time, context, and multiple levels—will promote a more robust body of collective leadership research and practice. In particular, we review and integrate three complementary methodological approaches—organizational discourse analysis, relational event modeling, and dynamic network analysis—which have the flexibility to address these challenges. The purpose of this article is to demonstrate the utility of these methodological approaches for addressing major methodological challenges within the field of collective leadership. Through this effort, we aim to facilitate conversation across disparate streams of research and encourage researchers to explore how novel research questions and perspectives might be advanced through leveraging these methods, either in isolation or in combination.

Aging in the United States will be defined by differences in health and longevity among populations. Diversity among the aged population is expected to increase. While investigators must contend with generalizability to enhance rigor, biomedical research holds great promise in exploring determinants of health for populations groups. Biomedical research explores the impact of various determinants on health and longevity. Health disparities research related to aging serves as an important scientific approach for researchers to maintain clarity in generalizability, with a focus on a breadth of determinants in multiple levels of analysis. Moreover, health disparities research related to aging holds the biomedical research enterprise accountable to principles of equity for understanding and addresing the health and aging of disproportionately affected population groups in society.
