Conceptual Frameworks and Methods for Advancing Invasion Ecology

Invasion ecology has much advanced since its early beginnings. Nevertheless, explanation, prediction, and management of biological invasions remain difficult. We argue that progress in invasion research can be accelerated by, first, pointing out difficulties this field is currently facing and, second, looking for measures to overcome them. We see basic and applied research in invasion ecology confronted with difficulties arising from (A) societal issues, e.g., disparate perceptions of invasive species; (B) the peculiarity of the invasion process, e.g., its complexity and context dependency; and (C) the scientific methodology, e.g., imprecise hypotheses. To overcome these difficulties, we propose three key measures: (1) a checklist for definitions to encourage explicit definitions; (2) implementation of a hierarchy of hypotheses (HoH), where general hypotheses branch into specific and precisely testable hypotheses; and (3) platforms for improved communication. These measures may significantly increase conceptual clarity and enhance communication, thus advancing invasion ecology

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Insights For Research And Practice: What We Learn About Fraud From Other Disciplines

We survey academic literature from non-accounting publications related to fraud and financial crimes: (1) to better understand the nature and extent of fraud acts from the perspective of non-accounting research; (2) to share with accounting researchers and practitioners ideas, theories, variables, constructs, and research designs used in other fields that might inform anti-fraud research and actions in accounting; and (3) to highlight opportunities for future research. This project extends the work of Hogan, Rezaee, Riley, and Velury (2008) and Trompeter, Carpenter, Desai, Jones, and Riley (2013) who completed fraud research synthesis projects in conjunction with the Auditing Section of the American Accounting Association for the Public Company Accounting Oversight Board (PCAOB). Our literature survey goes beyond immediate practice concerns and summarizes fraud-related literature that might inform research as well as practice in the future from approximately 30 journals in criminology, ethics, psychology, and sociology

A Synthesis Of Fraud-Related Research

We synthesize academic literature related to fraudulent financial reporting with dual purposes: (1) to better understand the nature and extent of the existing literature on financial reporting fraud, and (2) to highlight areas where there is need for future research. This project extends the work of Hogan et al. (2008), who completed a similar synthesis project, also sponsored by the Auditing Section of the American Accounting Association, in 2005. We synthesize the literature related to fraud by examining accounting and auditing literature post-Hogan et al. (2008) and by summarizing relevant fraud literature from outside of accounting. We review publications in accounting and related disciplines including criminology, ethics, finance, organizational behavior, psychology, and sociology. We synthesize the research around a model that illustrates the auditor\u27s approach to fraud. The model incorporates auditors\u27 use of the fraud triangle (i.e., management\u27s incentive, attitude, and opportunity to commit fraud), their assessment of the existence and effectiveness of the client\u27s anti-fraud measures (e.g., corporate governance mechanisms and internal controls), and their consideration of possible fraud schemes and concealment techniques when making an overall fraud risk assessment of the client. The model further illustrates how auditors can incorporate this assessment into an overall strategy to detect fraud by implementing appropriate fraud-detection procedures. We summarize the recent literature of each component of the model and suggest avenues for future research

Comments by the Auditing Standards Committee of the Auditing Section of the American Accounting Association on the PCAOB Rulemaking Docket Matter 029: PCAOB Release No. 2011-007, Improving Transparency Through Disclosure of Engagement Partner and Certain Other Participants in Audits

In October 2011, the Public Company Accounting Oversight Board (PCAOB or Board) issued a release to solicit public comment on amendments to its standards that would improve the transparency of pubic company audits. The objective of the release was to solicit public comments on a proposed standard that would (1) require registered public accounting firms to disclose the name of the engagement partner in the audit report, (2) amend the Board\u27s Annual Report Form to require registered firms to disclose the name of the engagement partner for each audit report already required to be reported on the form, and (3) require disclosure in the audit report of other independent public accounting firms and other persons that took part in the audit. The PCAOB provided for a 91-day exposure period (from October 11, 2011, to January 9, 2012) for interested parties to examine the release and provide comments. The Auditing Standards Committee of the Auditing Section of the American Accounting Association provided the comments in the letter below to the PCAOB on PCAOB Rulemaking Docket Matter 029: PCAOB Release No. 2011-007, Improving Transparency Through Disclosure of Engagement Partner and Certain Other Participants in Audits
