Working with pluralism: determining quality in qualitative research
No full textThis Feature Topic contains four articles that address the determination of quality in qualitative research by exploring the use of criteria from the perspective of reviewers, editors, and/ or authors. In this introductory article, the authors assert that these explorations represent an important move away from employing listings of static criteria to adjudicate and develop qualitative research. In its place, we see the making of quality as situated in methodological pluralism that occurs both in comparison with quantitative research and also within qualitative research. This fact complicates and enriches the task of determining quality and also suggests ways forward for the academic community

Governance for adaptive capacity and resilience in the U.S. water sector
No full textWater utility managers play potentially important roles in current and future transitions toward more adaptive and
sustainable approaches to water management. We report the results of qualitative interviews and focus groups designed to explore the
perspectives of 22 water utility managers in the United States regarding pressures, challenges, and opportunities facing their
organizations and communities. Overall, the study participants characterized their jobs as requiring a delicate balance between
innovation and reliability, with no room for error in delivering abundant, clean water, but opportunities for creative problem-solving
and forward planning. They demonstrated capacity for embracing changes that benefit the longer term future while imposing shortterm
costs on their own organizations. Coding of transcripts generated 17 major themes (11 problem categories and six solution
categories), which overlap meaningfully with results of previous research on resilience, adaptability, and transformability of socialecological
systems. Overlapping themes include social learning and development of social capital through various forms of collaboration,
communication, and citizen and stakeholder engagement, as well as capacity for innovation and sufficient authority to make decisions
based on system needs without undue political interference or burdensome adherence to rigid rule structures
“Biochemical and physical correlates of DNA contamination in archaeological human bones and teeth excavated at Matera, Italy”
No full textResults of DNA studies of early medieval human skeletons from an early medieval cemetery site excavated by the author Paul Arthur at S. Lucia alle Malve, Matera. The study regards particularly the problems of contamination and validity of genetic analysis
Accounting Quality and Firm-Level Capital Investment
No full textThis study examines how accounting quality relates to firm-level capital investment efficiency. Our first hypothesis is that higher quality accounting enhances investment efficiency by reducing information asymmetry between managers and outside suppliers of capital. Our second hypothesis is that this effect should be stronger in economies where financing is largely provided through arm's-length transactions compared with countries where creditors supply more capital. Our results are consistent with these hypotheses both across and within countries. They are robust to alternative econometric specifications, different measures of accounting quality and investment-cash flow sensitivity, and numerous control variables
