Identification in a regression discontinuity (RD) design hinges on the discontinuity in the probability of treatment when a covariate (assignment variable) exceeds a known threshold. If the assignment variable is measured with error, however, the discontinuity in the relationship between the probability of treatment and the observed mismeasured assignment variable may disappear. Therefore, the presence of measurement error in the assignment variable poses a challenge to treatment effect identification. This chapter provides sufficient conditions to identify the RD treatment effect using the mismeasured assignment variable, the treatment status and the outcome variable. We prove identification separately for discrete and continuous assignment variables and study the properties of various estimation procedures. We illustrate the proposed methods in an empirical application, where we estimate Medicaid takeup and its crowdout effect on private health insurance coverage.

Conventional tests of the regression discontinuity design’s identifying restrictions can perform poorly when the running variable is discrete. This paper proposes a test for manipulation of the running variable that is consistent when the running variable is discrete. The test exploits the fact that if the discrete running variable’s probability mass function satisfies a certain smoothness condition, then the observed frequency at the threshold has a known conditional distribution. The proposed test is applied to vote tally distributions in union representation elections and reveals evidence of manipulation in close elections that is in favor of employers when Republicans control the NLRB and in favor of unions otherwise.

This study contributes to the understanding of the health effects of pesticides exposure and of how pesticides have been and should be regulated.

This study presents literature reviews for the period 2000–2013 on (i) the health effects of pesticides and on (ii) preference valuation of health risks related to pesticides, as well as a discussion of the role of benefit-cost analysis applied to pesticide regulatory measures.

This study indicates that the health literature has focused on individuals with direct exposure to pesticides, i.e. farmers, while the literature on preference valuation has focused on those with indirect exposure, i.e. consumers. The discussion highlights the need to clarify the rationale for regulating pesticides, the role of risk perceptions in benefit-cost analysis, and the importance of inter-disciplinary research in this area.

This study relates findings of different disciplines (health, economics, public policy) regarding pesticides, and identifies gaps for future research.

A comparative analysis of the results of two longitudinal studies conducted a decade apart, among research post-graduate students, with the purpose of understanding the progress in their information literacy (IL) skills, forms the content of this report. The analysis is based on the application of the Research and Information Search Expertise (RISE) model, which traces students’ progression across four stages of expertise. Such progression was measured across two dimensions of knowledge: that of information sources/databases and that of information search skills. Both studies adopted basic interpretive qualitative methods involving direct observation, interviews, think-aloud protocols, and survey questionnaires, during each of the five interventions, which were spread over a one to one-and-half year period. Scaffolding training was provided at each meeting and data were collected to assess the influence of such training on development of search expertise. A comparison of the findings reveals that students in both studies advance in their IL skills largely in a similar manner. Scaffolding support was found to help both dimensions of knowledge and that lack of one or the other type of knowledge could hinder their ability to find relevant sources for their research. The studies make evident the need for training programs for higher education students, to improve both their knowledge of information sources and their search techniques, tailor-made to closely correlate to their specific information needs. The studies provide insights into student behaviors in the development of IL skills, and the RISE model offers a framework for application to other similar research.

Changing environments demand that police improve their effectiveness in reducing crime, while maintaining community confidence, support and legitimacy. How can police agencies encourage third parties to take responsibility for crime problems while avoiding inequitable outcomes?

The evidence for effective policing for crime reduction is examined, with a focus on third party policing. Potential adverse outcomes are discussed, and a normative framework is proposed.

Third party policing that is both effective and legitimacy enhancing is possible, if four key principles are observed. These are conducting a broad planning approach that includes consideration of the detriments as well as the benefits of strategies especially to vulnerable community members, clearly identified goals and the use of the least coercive means possible, clearly articulated policies and protocols, and institutional and individual accountability for strategy implementation and outcomes.

There is emerging evidence about the effectiveness of regulatory approaches to crime reduction, such as third party policing, but little attention has been paid to its potential for inequitable outcomes and impact on police legitimacy.

This chapter overviews the articulation of inquiry in the three International Baccalaureate (IB) levels, Primary Years (ages 3–12), Middle Years (11–16), and the Diploma Program (16–18) that is widely accepted by universities for matriculation. It reviews inquiry-based instruction in the publicly available IB research literature. The IB advocates inquiry as its pedagogical approach. We identified empirical classroom research involving IB teachers or students from four databases; 35 reports matched inclusion criteria and 31 of these had appeared in gifted-education journals. The IB’s inquiry philosophy, interdisciplinary emphasis, and specific elements in the Diploma Program such as the Theory of Knowledge course, a program entitled Creativity, Action, and Service, and the Extended Essay, comprise qualities that should inform higher education. There has been disproportionate attention to the planning part of inquiry (e.g., generating worthy questions and deciding how to answer them) versus enactment or reflection; this leaves room for other research input about enacting inquiry in university instruction that creates a cycle of creative engagement. Successful IB experiences, through some of the IB pedagogy and content, raised learners’ expectations about their higher education learning experiences. However, as one moves from the Primary Years through to the Diploma Program, students report increasing “teaching to the test” and content-coverage that constrain inquiry opportunities students value. The importance of providing detailed, supportive, step-by-step introductions to inquiry, and attending to the social and emotional correlates of the substantive learning, were highlighted.

The long-term financial stability of hospital systems represents a “grand challenge” in health care. New ownership forms, such as private equity (PE), promise to achieve better financial performance than nonprofit or for-profit systems. In this study, we compare two systems with many similarities, but radically different ownership structures, missions, governance, and merger and acquisition (M&A) strategies. Both were nonprofit, religious systems serving low-income communities – Montefiore Health System and Caritas Christi Health Care.

Montefiore's M&A strategy was to invest in local hospitals and create an integrated regional system, increasing revenues by adding primary doctors and community hospitals as feeders into the system and achieving efficiencies through effective resource allocation across specialized units. Slow and steady timing of acquisitions allowed for organizational learning and balancing of debt and equity. By 2019, it owned 11 hospitals with 40,000 employees and had strong positive financials and low reliance on debt.

By contrast, in 2010, PE firm Cerberus Capital bought out Caritas (renamed Steward Health Care System) and took control of the Board of Directors, who set the system's strategic direction. Cerberus used Steward as a platform for a massive debt-driven acquisition strategy. In 2016, it sold off most of its hospitals’ property for $1.25 billion, leaving hospitals saddled with long-term inflated leases; paid itself almost $500 million in dividends; and used the rest for leveraged buyouts of 27 hospitals in 9 states in 3 years. The rapid, scattershot M&A strategy was designed to create a large corporation that could be sold off in five years for financial gain – not for health care integration. Its debt load exploded, and by 2019, its financials were deeply in the red. Its Massachusetts hospitals were the worst financial performers of any system in the state. Cerberus exited Steward in 2020 in a deal that left its physicians, the new owners, holding the debt.

Incivility is widespread in the workplace and has been shown to have significant affective and behavioral consequences. However, the authors still have a limited understanding as to whether, how and when discrete incivility events impact team performance. Adopting a resource depletion perspective and focusing on the cognitive implications of such events, the authors introduce a multi-level model linking the adverse effects of such events on team members’ working memory – the “workbench” of the cognitive system where most planning, analyses, and management of goals occur – to team effectiveness. The model which the authors develop proposes that that uncivil interpersonal behavior in general, and rudeness – a central manifestation of incivility – in particular, may place a significant drain on individuals’ working memory capacity, affecting team effectiveness via its effects on individual performance and coordination-related team emergent states and action-phase processes. In the context of this model, the authors offer an overarching framework for making sense of disparate findings regarding how, why and when incivility affects performance outcomes at multiple levels. More specifically, the authors use this framework to: (a) suggest how individual-level cognitive impairment and weakened coordinative team processes may mediate these incivility-based effects, and (b) explain how event, context, and individual difference factors moderators may attenuate or exacerbate these cognition-mediated effects.

Unlike other populations, entrepreneurs may be unable to fully escape from job-related stress due to their financial and/or psychological connection to their ventures. The authors argue that stress is a universal, intangible variable that profoundly influences the entrepreneurial process. In the present review, the authors critically synthesize past literature to evaluate the substantive body of research on stress in entrepreneurship and assess the impact of stress on individuals’ well-being. The authors find that entrepreneurial stress stems from role conflict or overload, issues related to business operations, and concerns from life outside the venture. Further, stress may result in changes to personal satisfaction and psychological well-being, contingent upon an individual’s stress tolerance, coping strategies, or recovery practices. The entrepreneurial process, from creation to exit, is comprised of several transition periods, all of which are uniquely stressful. The authors explore the implications of our findings by discussing stressors that may manifest during each stage of the entrepreneurial process. Therefore, the authors respond to calls for more dynamic investigation of entrepreneurial stress while also highlighting the need for more research into stressors associated with specific entrepreneurial activities.
