Despite its contemporary and theoretical importance in numerous social scientific disciplines, institutional confidence research is limited by a lack of consensus regarding the distinctions and relationships among related constructs (e.g., trust, confidence, legitimacy, distrust, etc.). This study examined four confidence-related constructs that have been used in studies of trust/confidence in the courts: dispositional trust, trust in institutions, obligation to obey the law, and cynicism. First, the separability of the four constructs was examined by exploratory factor analyses. Relationships among the constructs were also assessed. Next, multiple regression analyses were used to explore each constructs independent contribution to confidence in the courts. Finally, a second study replicated the first study and also examined the stability of the institutional confidence constructs over time. Results supported the hypothesized separability of, and correlations among, the four confidence-related constructs. The extent to which the constructs independently explained the observed variance in confidence in the courts differed as a function of the specific operationalization of confidence in the courts and the individual predictor measures. Implications for measuring institutional confidence and future research directions are discussed.

Although several frameworks for assessing the resilience of social-ecological systems (SESs) have been developed, some practitioners may not have sufficient time and information to conduct extensive resilience assessments. We have presented a simplified approach to resilience assessment that reviews the scientific, historical, and social literature to rate the resilience of an SES with respect to nine resilience properties: ecological variability, diversity, modularity, acknowledgement of slow variables, tight feedbacks, social capital, innovation, overlap in governance, and ecosystem services. We evaluated the effects of two large-scale projects, the construction of a major dam and the implementation of an ecosystem recovery program, on the resilience of the central Platte River SES (Nebraska, United States). We used this case study to identify the strengths and weaknesses of applying a simplified approach to resilience assessment. Although social resilience has increased steadily since the predam period for the central Platte River SES, ecological resilience was greatly reduced in the postdam period as compared to the predam and ecosystem recovery program time periods.

Deconstructing public confidence in state courts

Joseph A. Hamm; Lisa M. PytlikZillig; Mitchel N. Herian; Brian H. Bornstein; Alan J. Tomkins; Lesa Hoffman

Abstract Although researchers have consistently demonstrated the importance of confidence in public institutions like the courts, relatively little attention has been paid to understanding what confidence itself really is. This article presents data from two samples of community members, thereby building on and extending a preliminary investigation that sought to understand constructs related to confidence in state courts with student samples. Structural equation modelling results provide support for the dimensionality of the measures and indicate that dispositional trust has little to no independent effect on confidence. However, tendency to trust in governmental institutions, cynicism toward the law and felt obligation to obey the law are important predictive constructs. The current results are important both for researchers seeking to understand confidence in the courts and the judges and administrators who would seek to increase it.

On the influence of trust in predicting rural land owner cooperation with natural resource management institutions

Joseph A. Hamm; Lesa Hoffman; Alan J. Tomkins; Brian H. Bornstein

Contemporary natural resource management (NRM) emphasises the role of the public in general and land owners in particular as voluntary participants in the process. Understanding the role of trust in voluntary cooperation is therefore critical, but the current state of the relevant literature is such that it fails to systematically address a few important issues. This inquiry sought to address these issues by presenting and testing a model of land owners’ trust in and cooperation with a NRM institution. The model hypothesises that the six major drivers of trust in this context (dispositional trust, care, competence, confidence, procedural fairness and salient values similarity) are distinct but correlated constructs that drive cooperation and whose effects are moderated by the sophistication (relevant knowledge and experience) of the trustor. The results provide complicated partial support for the hypotheses and suggest that (1) although the six constructs are separable, their effects on cooperation are not as distinct as expected; (2) the most important consideration for cooperation may, in fact, be a broader evaluation – potentially a willingness to be vulnerable to the target and (3) if sophistication is an important moderator of the effect of trust, it is likely to require only a low level of general sophistication about the target institution to encourage trustors to rely most strongly on their perceptions of the institution itself.

ABSTRACT Using confirmatory factor analyses and multiple indicators per construct, we examined a number of theoretically derived factor structures pertaining to numerous trust-relevant constructs (from 9 to 12) across four institutional contexts (police, local governance, natural resources, state governance) and multiple participant-types (college students via an online survey, community residents as part of a citys budget engagement activity, a random sample of rural landowners, and a national sample of adult Americans via an Amazon Mechanical Turk study). Across studies, a number of common findings emerged. First, the best fitting models in each study maintained separate factors for each trust-relevant construct. Furthermore, post hoc analyses involving addition of higher-order factors tended to fit better than collapsing of factors. Second, dispositional trust was easily distinguishable from the other trust-related constructs, and positive and negative constructs were often distinguishable. However, the items reflecting positive trust attitude constructs or positive trustworthiness perceptions showed low discriminant validity. Differences in findings between studies raise questions warranting further investigation in future research, including differences in correlations among latent constructs varying from very high (e.g. 12 inter-factor correlations above .9 in Study 2) to more moderate (e.g. only three correlations above .8 in Study 4). Further, the results from one study (Study 4) suggested that legitimacy, fairness, and voice were especially highly correlated and may form a single higher-order factor, but the other studies did not. Future research is needed to determine when and why different higher-order factor structures may emerge in different institutional contexts or with different samples.

In this article we summarize histories of nonlinear, complex interactions among societal, legal, and ecosystem dynamics in six North American water basins, as they respond to changing climate. These case studies were chosen to explore the conditions for emergence of adaptive governance in heavily regulated and developed social-ecological systems nested within a hierarchical governmental system. We summarize resilience assessments conducted in each system to provide a synthesis and reference by the other articles in this special feature. We also present a general framework used to evaluate the interactions between society and ecosystem regimes and the governance regimes chosen to mediate those interactions. The case studies show different ways that adaptive governance may be triggered, facilitated, or constrained by ecological and/or legal processes. The resilience assessments indicate that complex interactions among the governance and ecosystem components of these systems can produce different trajectories, which include patterns of (a) development and stabilization, (b) cycles of crisis and recovery, which includes lurches in adaptation and learning, and (3) periods of innovation, novelty, and transformation. Exploration of cross scale (Panarchy) interactions among levels and sectors of government and society illustrate that they may constrain development trajectories, but may also provide stability during crisis or innovation at smaller scales; create crises, but may also facilitate recovery; and constrain system transformation, but may also provide windows of opportunity in which transformation, and the resources to accomplish it, may occur. The framework is the starting point for our exploration of how law might play a role in enhancing the capacity of social-ecological systems to adapt to climate change.

Fair Process, Trust, and Cooperation: Moving Toward an Integrated Framework of Police Legitimacy

Joseph A. Hamm; Rick Trinkner; J. D. Carr

Positive public perceptions are a critical pillar of the criminal justice system, but the literature addressing them often fails to offer clear advice regarding the important constructs or the relationships among them. The research reported here sought to take an important step toward this clarity by recruiting a national convenience sample to complete an online survey about the police in the respondent’s community, which included measures of the process-based model of legitimacy and the classic model of trust. Our results suggest that although both are predictive, the models can be integrated in a way that allows the strengths of each model to address the weaknesses of the other. We therefore present this model as a first step toward an Integrated Framework of Police Legitimacy that can meaningfully incorporate much of the existing scholarship and provide clearer guidance for those who seek to address these constructs in research and practice.

Environmental Stigma Resident Responses to Living in a Contaminated Area

Jie Zhuang; Jeff Cox; Shannon Cruz; James W. Dearing; Joseph A. Hamm; Brad L. Upham

This article examined the extent to which residents living in the Midland–Saginaw–Bay City area in Eastern Michigan felt stigmatized due to industrial contamination. Seventy in-depth interviews were conducted with local residents, focusing on the extent to which they experienced three aspects of stigma—affective, cognitive, and behavioral. Results indicated that although some participants were not concerned with living in a contaminated community, local residents largely perceived dioxin as a risk to individual health and the local environment. Concern, shock, and irritation were typical affective responses at the time participants learned of the contamination. Several participants indicated a feeling of embarrassment and fear of being rejected by others because of the stigma associated with industrial contamination. Instead of actively seeking information about dioxin contamination and remediation, participants often relied on information provided to them by government officials. Behaviorally, participants avoided eating locally caught fish and prepared fish more carefully in order to avoid exposure to contaminants. As a whole, this study provided insight to understand affective, cognitive, and behavioral responses to environmental stigma.

Working with Covariance: Using Higher-Order Factors in Structural Equation Modeling with Trust Constructs

Joseph A. Hamm; Lesa Hoffman

Clarifying the “conceptual morass” of the social science of trust is a critical endeavor, and Structural Equation Modeling (SEM) is an important tool for researchers seeking to investigate the relationships among and relative influence of the many trust constructs in this expanding literature. Problematically, however, the often conceptually overlapping nature of the constructs themselves can create covariance problems that are only exacerbated by SEM’s ability to partition shared and unshared variance among indicators. These challenges can, in some situations, entirely preclude researchers from using SEM to test theoretically important hypotheses. There are a number of potential strategies available to researchers to address these problems, notably including both item- and factor-level aggregation techniques. Importantly, however, these aggregation strategies often compromise many of the benefits that make SEM so attractive in the first place. We therefore recommend that researchers with strongly correlated latent constructs test a specific alternative model in which higher-order factors are used to predict the covariance among the latent factors. These models address the problems that arise from working with excessive covariance while preserving the conceptual and statistical distinctiveness of the lower-order factors and permitting researchers to test their independent influence on important outcomes. To aid in illustrating this approach, the chapter includes a real-world data example in which various alternative model specifications are tested, highlighting the utility of higher-order factor models for trust researchers.

This study examined a knowledge-centered theory of institutional trust development. In the context of trust in water regulatory institutions, the moderating impact of knowledge was tested to determine if there were longitudinal changes in the bases of institutional trust as a function of increases in knowledge about a target institution. We hypothesized that as people learn about an institution with which they were previously unfamiliar, they begin to form more nuanced perceptions, distinguishing the new institution from other institutions and relying less upon their generalized trust to estimate their trust in that institution. Prior to having specific, differential information about a new institution, we expected institutional trust to be a function of generalized trust variables such as dispositional trust and trust in government. The longitudinal experiment involved 185 college students randomly assigned to one of three information conditions. Every 3 months for 15 months, participants read information about water regulatory institutions or a control institution. At each time point, participants reported their trust in and perceptions of the trust- and distrust-worthiness of the water regulatory institutions. Participants also completed measures of knowledge of water regulatory institutions, dispositional trust, and governmental trust. Our manipulation check indicated that, as expected, those in the experimental group increased in subjective knowledge of water regulatory institutions to a greater extent than those in the control condition. Consistent with our hypotheses, there was some evidence that, compared to the control group, the experimental group relied less on their general trust in government as a basis for their trust in water regulatory institutions. However, contrary to our hypotheses, there was no evidence the experimental group relied less on dispositional trust as a basis for institutional trust. There also was some evidence the experimental group’s trust in water regulatory institutions was less affected by fluctuations of trustworthiness (but not distrustworthiness) perceptions over time. This suggests that knowledge results in the development of more stable institutional trust attitudes, but that trustworthiness and distrustworthiness perceptions may operate somewhat differently when impacting trust in specific institutions.
