Statistics of extremes under random censoring

We investigate the estimation of the extreme value index when the data are subject to random censorship. We prove, in a unified way, detailed asymptotic normality results for various estimators of the extreme value index and use these estimators as the main building block for estimators of extreme quantiles. We illustrate the quality of these methods by a small simulation study and apply the estimators to medical data.Comment: Published in at http://dx.doi.org/10.3150/07-BEJ104 the Bernoulli (http://isi.cbs.nl/bernoulli/) by the International Statistical Institute/Bernoulli Society (http://isi.cbs.nl/BS/bshome.htm

Development and Implementation of Methods to Study Crystallization in Cheese

Dissolved compounds and ions, including mineral elements and products of microbial metabolism, are present in many cheeses in relatively high concentrations. These dissolved substances may precipitate from the aqueous phase of cheese to form sparingly soluble crystals that can impart a crunchy, gritty, or sandy texture on the cheese. In the present work, optical and diffractometric methods were optimized for use with cheese samples to identify crystal phases in several cheese varieties. These techniques, which included powder X-ray diffractometry (PXRD), single crystal X-ray diffractometry (SCXRD), and petrographic microscopy (PM) have traditionally been used on geological specimens that are quite different from the cheese samples used in the present study. Nonetheless, these techniques were successfully used to gain valuable insight into crystal development in cheese. Powder X-ray diffractometry was optimized to minimize the occurrence of artifacts that may occur due to the high water content and low crystallinity of some cheese samples. The use of enhanced sample preparation techniques facilitated the identification of organic and inorganic crystal phases such as tyrosine, leucine, brushite (CaHPO4·2H2O), and calcite (CaCO3) in hard and soft cheeses. SCXRD was used to determine the crystal structures of ikaite and struvite, which had been tentatively identified in washed-rind cheese using PXRD. PM was used to observe morphological and optical properties of crystals in white mold cheese and washed-rind cheese. In two subsequent aging studies, PXRD was used to determine the approximate timing of crystal nucleation in the rinds of white mold cheese and washed-rind cheese. These observations were paired with inductively coupled plasma-atomic emission spectroscopy (ICP-AES) data to demonstrate that the onset of crystallization in the rinds coincided with a diffusion phenomenon in which mineral ions diffused from the center of the cheese and became concentrated in the rind. PM observations demonstrated that maximum crystal size in the rinds generally increased as aging progressed. These observations will be useful in future work that investigates the impact of crystallization on sensory properties of cheese

Sciunits: Reusable Research Objects

Science is conducted collaboratively, often requiring knowledge sharing about computational experiments. When experiments include only datasets, they can be shared using Uniform Resource Identifiers (URIs) or Digital Object Identifiers (DOIs). An experiment, however, seldom includes only datasets, but more often includes software, its past execution, provenance, and associated documentation. The Research Object has recently emerged as a comprehensive and systematic method for aggregation and identification of diverse elements of computational experiments. While a necessary method, mere aggregation is not sufficient for the sharing of computational experiments. Other users must be able to easily recompute on these shared research objects. In this paper, we present the sciunit, a reusable research object in which aggregated content is recomputable. We describe a Git-like client that efficiently creates, stores, and repeats sciunits. We show through analysis that sciunits repeat computational experiments with minimal storage and processing overhead. Finally, we provide an overview of sharing and reproducible cyberinfrastructure based on sciunits gaining adoption in the domain of geosciences

Stress Management Among Healthcare Workers During a Pandemic

Background: Approximately- 59 million healthcare workers worldwide provide healthcare at any given time. Many of these workers experienced increased stress and daily adversity during the COVID-19 pandemic. Purpose: The purpose of this DNP project was to evaluate if the use of a newly developed, evidenced-based mindfulness meditation program could help front-line healthcare workers manage perceived stress. There were two specific DNP project aims. The first was to develop and implement an evidence-based mindfulness meditation program to help front-line healthcare workers manage pandemic-related stress during the pandemic. The second aim was to evaluate the use and impact of the web-based mindfulness meditation program on perceived stress among participants. Methodology: One group of primary care healthcare providers at a south Florida clinic were assessed before, and two weeks after, the mindfulness meditation program. A survey was administered remotely. The Perceived Stress Scale (PSS), a psychological instrument, was used to measure perceived stress among participants. Additionally, survey items were developed to assess familiarity with mindfulness practice and the frequency of use of the mindfulness practice. Participant demographics included age, gender, and professional role. Intervention: A 30-minute mindfulness program that focused on meditation techniques was available on YouTube for a two-week period. Results: Eleven healthcare workers participated in the project. Data were available for 11 participants before the intervention and 8 participants post-intervention. The participants were QUALITY IMPROVEMENT PROJECT primarily women (n = 10). The mean PSS score prior to the intervention was 21.90 (SD = 8.05), and after the intervention the PSS score was 17.37 (SD = 9.11). Both mean scores indicate moderate levels of stress. There were no statistically significant differences pre versus post-intervention in PSS mean scores or individual PSS items. Following exposure to the web-based intervention, most of the participants, 57% (n = 4), found the mindfulness program to be helpful “fairly often,” while 28% (n = 2) found it to be very helpful. Conclusion: Web-based mindfulness meditation programs have been proven to be well-received, feasible, and effective in decreasing perceived stress among healthcare workers. Administrators should consider making mindfulness meditation programs available to employees to address stress, especially during a pandemic.
