Exploring the use of the Delphi method in accounting information systems research

Recent focus on the diversity of research methodologies available to accounting information systems (AIS) scholars has led researchers to suggest the Delphi method has reached the limits of its usefulness. Using a review of the accounting and information systems literature, we suggest such a finding is premature for the AIS discipline. The Delphi method is especially useful in reducing ambiguity through the use of expert panels of both practitioners and experts and informing relevant and timely issues facing organizations. In essence, the Delphi method has potential to provide both rigor and relevance to AIS researchers. Our purpose is to review the prior literature on the use of the Delphi method and discuss potential areas of research within the AIS discipline where the method might add value. Based on this review, we develop a series of guidelines on how to properly develop, administer, and assess panel responses and then use an illustrative study example that explores IT risks in operations. We conclude with a discussion of the value of the Delphi method and provide insight into its limitations.     

A comparison of treatment patterns,healthcare resource utilization,and costs among young adult Medicaid beneficiaries with schizophrenia treated with paliperidone palmitate or oral atypical antipsychotics in the US

Abstract

Background: Much of the burden associated with schizophrenia is attributed to its early onset and chronic nature. Treatment with once monthly paliperidone palmitate (PP1M) is associated with lower healthcare utilization and better adherence as compared to oral atypical antipsychotics (OAAs). This study aimed to evaluate real-world effectiveness of PP1M and OAA therapies among US-based adult Medicaid patients with schizophrenia, overall and among young adults aged 18–35 years.

Methods: Adult patients with a diagnosis of schizophrenia and at least two claims for PP1M or OAA between January 1, 2010 and December 31, 2014 were selected from the IBM Watson Health MarketScan Medicaid Database. Treatment patterns and healthcare resource utilization and costs were compared between PP1M and OAA treatment groups following inverse probability of treatment (IPT) weighting to adjust for potential differences. Utilization and cost outcomes were estimated using OLS and weighted Poisson regression models.

Results: After IPT weighting, the young adult PP1M and OAA cohorts were comprised of 3,095 and 3,155 patients, respectively. PP1M patients had a higher duration of continuous treatment exposure (168.2 vs 132.5 days, p?=?.004) and better adherence on the index medication (proportion of days covered ≥80%: 19.0% vs 17.1%, p?<?.049). Young adults treated with PP1M were 37% less likely to have an all-cause inpatient admission (odds ratio [OR]?=?0.63, 95% confidence interval [CI]?=?0.53–0.74) and 33% less likely to have an ER visit (OR?=?0.67, 95% CI?=?0.55–0.81) compared to OAA young adult patients, but 27% more likely to have an all-cause outpatient office visit (OR?=?1.27, 95% CI?=?1.02–1.56). PP1M patients incurred significantly lower medical costs as compared to OAA patients.

Conclusions: Medicaid patients with schizophrenia treated with PP1M have higher medication adherence and have fewer hospitalizations as compared to patients treated with OAAs. PP1M may lead to reduced healthcare utilization and improved clinical outcomes.     

The Editors and Authors of Economics Journals: a Case of Institutional Oligopoly?

This paper examines data on the institutional backgrounds of editors and authors of the top 30 economics journals, identified by their 1995 citation impact. It is revealed, for example, that 70.8% of the journal editors were located in the United States, and twelve U.S. universities accounted for the location of more than 38.9%. Concerning journal article authors, 65.7% were located in U.S. institutions and twelve U.S. universities accounted for 21.8%. Arguably, the degree of institutional and geographical concentration of editors and authors may be unhealthy for innovative research in economics.     

Nonparametric Kernel Method to Hedge Downside Risk

We propose a nonparametric kernel estimation method (KEM) that determines the optimal hedge ratio by minimizing the downside risk of a hedged portfolio, measured by conditional value‐at‐risk (CVaR). We also demonstrate that the KEM minimum‐CVaR hedge model is a convex optimization. The simulation results show that our KEM provides more accurate estimations and the empirical results suggest that, compared to other conventional methods, our KEM yields higher effectiveness in hedging the downside risk in the weather‐sensitive markets.     

Class Debates in Intermediate Microeconomics: Social Economics and Pluralist Perspectives

Abstract

This paper proposes the use of class debates in an intermediate-level microeconomics course to introduce early to mid-career undergraduate students to socially embedded and pluralist perspectives, political-economic processes, and policy analyses. Using data from three semesters of class debates in an intermediate microeconomics course, we argue that this activity is a beneficial way to stimulate student interest in social economics, especially in the ethical, political economy, and economic justice aspects of economics and policy. We carried out three allied activities: participation in the debate, a learning self-assessment survey, and a five-page memo providing a balanced analysis of the policy conundrums surrounding the issue under discussion. We discuss three aspects of these class debates relevant to social economists: student attention to processes of knowledge construction, cognizance of power in socioeconomic life, and engagement with economic justice and ethics.     

Estimating the Value of an Early-Warning System

An early-warning system generates economic value to the extent that it improves decision making. The value of the information hinges on the degree to which a timely response, aided by warnings, facilitates successful damage mitigation. USDA's Coordinated Framework for Soybean Rust includes a network of sentinel soybean plots and wild kudzu stands monitored by extension agents for the presence of soybean rust, a potentially recurring threat to the U.S. soybean crop since 2005. The linchpin in this early-warning system is a website that provides near real-time, county-level information on the location of the disease. We consider factors that may influence information value.     

Integrating Pragmatism and Ethics in Entrepreneurial Leadership for Sustainable Value Creation

The relationship between entrepreneurship and ethics has largely been characterized as antithetical. In this article we develop a conceptual model integrating pragmatism, a philosophical approach that emphasizes experimentation and action characteristic of entrepreneurial leadership, with ethics to suggest that the two are not incompatible and that sustaining entrepreneurial leadership for value creation necessitates ethical action to build legitimacy. Case studies from the United States and India highlight the necessity of infusing pragmatism with ethics for sustainable entrepreneurial leadership.
