#1
Sean Shenghsiu Huang, Hyunjee Kim
Home health agencies (HHAs) are known to exploit the Medicare reimbursement schedule by targeting a specific number of therapy visits. These targeting behaviors cause unnecessary medical spending. The Centers for Medicare & Medicaid Services estimates that during fiscal year 2015, Medicare made more than $10 billion in improper payments to HHAs. Better understanding of heterogeneous gaming behaviors among HHAs can inform policy makers to more effectively oversee the home health care industry. This article aims to study how home health chains adjust and adopt new targeting behaviors as compared to independent agencies under the new reimbursement schedule...

BACKGROUND: Since clinical management of heart failure relies on weights that are self-reported by the patient, errors in reporting will negatively impact the ability of health care professionals to offer timely and effective preventive care. Errors might often result from rounding, or more generally from individual preferences for numbers ending in certain digits, such as 0 or 5. We apply fraud detection methods to assess preferences for numbers ending in these digits in order to inform medical decision making...

The aim of investigation was to evaluate a traceability system to detect industrial chicken meat among indigenous products, considering issues that could affect assignment accuracy. The dataset included 2 Italian indigenous meat breeds, namely Bionda Piemontese (2 ecotypes) and Bianca di Saluzzo, one broiler line, and 3 layer lines. Assignment tests were performed using a standard panel of 28 microsatellite loci. To evaluate effects of inbreeding and substructure on assignment accuracy, a simulated dataset was prepared...

OBJECTIVE: Central monitoring of multi-center clinical trials becomes an ever more feasible quality assurance tool, in particular for the detection of data fabrication. More widespread application, across both industry-sponsored as well as academic clinical trials, requires central monitoring methodologies that are both effective and relatively simple in implementation. STUDY DESIGN AND SETTING: We describe a computationally simple fraud detection procedure intended to be applied repeatedly and (semi-)automatically to accumulating baseline data, to detect data fabrication in multi-center trials as early as possible...

This review provides current information on the analytical methods used to identify food adulteration in the six most adulterated food categories: animal origin and seafood, oils and fats, beverages, spices and sweet foods (e.g. honey), grain-based food, and others (organic food and dietary supplements). The analytical techniques, both conventional and emerging, used to identify adulteration in these six food categories involve sensory, physicochemical, DNA-based, chromatographic, and spectroscopic methods, and have been combined with chemometrics, making these techniques more convenient and effective for the analysis of a broad variety of food products...

In the framework of sustainability and a circular economy, new ingredients for feed are desired and, to this end, initiatives for implementing such novel ingredients have been started. The initiatives include a range of different sources, of which insects are of particular interest. Within the European Union, generally, a new feed ingredient should comply with legal constraints in terms of 'yes, provided that' its safety commits to a range of legal limits for heavy metals, mycotoxins, pesticides, contaminants, pathogens etc...

The origins and authenticity against frauds are two essential aspects of food quality. In this work, a comprehensive quality evaluation method by FT-NIR spectroscopy and chemometrics were suggested to address the geographical origins and authentication of Chinese Ganoderma lucidum (GL). Classification for 25 groups of GL samples (7 common species from 15 producing areas) was performed using near-infrared spectroscopy and interval-combination One-Versus-One least squares support vector machine (IC-OVO-LS-SVM)...

Reproducibility in animal studies has been defined as the ability of a result to be replicated through independent experiments within the same or among different laboratories. Over the past few years, much has been written and said about the lack of reproducibility of animal studies. Reasons that are commonly cited for this lack of reproducibility include inappropriate study design, errors in conducting the research, and potential fraud. In the quest to understand the basis for this lack of reproducibility, scientists have not fully considered the potential ramifications on ethical constructs for animal research, animal welfare considerations in animal research programs, the regulatory environment, and oversight by IACUCs...

Over the past century, the allegation that the tort liability system incentivizes legal extortion and is chock-full of fraudulent claims has dominated public discussion and prompted lawmakers to ever-more-creatively curtail individuals' incentives and opportunities to seek redress. Unsatisfied with these conventional efforts, in recent years, at least a dozen corporate defendants have "discovered" a new fraud-fighting tool. They've started filing retaliatory RICO suits against plaintiffs and their lawyers and experts, alleging that the initiation of certain nonmeritorious litigation constitutes racketeering activity—while tort reform advocates have applauded these efforts and exhorted more "courageous" companies to follow suit...

Despite extensive research on unfamiliar face matching, little is known about factors that might affect matching performance in real-life scenarios. We conducted 2 experiments to investigate the effects of several such factors on unfamiliar face-matching performance in a passport-check scenario. In Experiment 1, we assessed the effect of professional experience on passport-matching performance. The matching performance of 96 German Federal Police officers working at Munich Airport was compared with that of 48 novices without specific face-matching experience...

OBJECTIVE: According to the investigations of the U.S. Government Accountability Office (GAO), health insurance fraud has caused an enormous pecuniary loss in the U.S. In Taiwan, in dentistry the problem is getting worse if dentists (authorized entities) file fraudulent claims. Several methods have been developed to solve health insurance fraud; however, these methods are like a rule-based mechanism. Without exploring the behavior patterns, these methods are time-consuming and ineffective; in addition, they are inadequate for managing the fraudulent dentists...

Background and Objectives: Elder financial exploitation, committed by individuals in positions of trust, and elder fraud, committed by predatory strangers, are two forms of financial victimization that target vulnerable older adults. This study analyzes differences between fraud and financial exploitation victims and tests routine activity theory as a contextual model for victimization. Routine activity theory predicts that criminal opportunities arise when a motivated offender and suitable target meet in the absence of capable guardians...

Matching unfamiliar faces is known to be difficult, and this can give an opportunity to those engaged in identity fraud. Here we examine a relatively new form of fraud, the use of photo-ID containing a graphical morph between two faces. Such a document may look sufficiently like two people to serve as ID for both. We present two experiments with human viewers, and a third with a smartphone face recognition system. In Experiment 1, viewers were asked to match pairs of faces, without being warned that one of the pair could be a morph...

Newell (1973) argued that progress in psychology was slow because research focused on experiments trying to answer binary questions, such as serial versus parallel processing. In addition, not enough attention was paid to the strategies used by participants, and there was a lack of theories implemented as computer models offering sufficient precision for being tested rigorously. He proposed a three-headed research program: to develop computational models able to carry out the task they aimed to explain; to study one complex task in detail, such as chess; and to build computational models that can account for multiple tasks...

Seafood fraud - often involving substitution of one species by another - has attracted much attention as it is prevalent worldwide. Whilst DNA analysis has helped to combat this type of fraud some of the methods currently in use are time-consuming and require sophisticated equipment or highly-trained personnel. This work describes the development of a new, real-time PCR TaqMan assay for the detection of ling (Molva molva) in seafood products. For this purpose, specific primers and a minor groove binding (MGB) TaqMan probe were designed to amplify the 81bp region on the cyt b gene...
