The rise of fentanyl and fentanyl analogs in the drug supply pose serious threats to public health. Much of these compounds enter the United States through shipping routes. Here we provide a method for fentanyl screening and analysis that utilizes pressure‐sensitive adhesive (PSA) lined paper to recover drug residues from parcel‐related surfaces. The paper used is commercially available repositionable notes (also called post‐it or sticky notes). From this paper, mass spectra were obtained by paper spray‐mass spectrometry (PS‐MS), where PSA paper served as both a sampling and analysis substrate. Seven fentanyl‐related compounds were analyzed: fentanyl, 4‐anilino‐N‐phenethylpiperidine (4‐ANPP), N,1‐diphenethyl‐N‐phenylpiperidin‐4‐amine (phenethyl‐4‐ANPP), valerylfentanyl, 4‐fluoroisobutyrylfentanyl (4‐FIBF), carfentanil, and p‐fluorofentanyl. These compounds were recovered by PSA paper and identified by PS‐MS from packaging tape and plastic at 50 ng and from cardboard and shipping labels at 100 ng. The impact of cutting agents on PS‐MS analysis of fentanyl analogs was explored. No trends of analyte suppression were found at high concentrations of the cutting agents caffeine, diphenhydramine, and lidocaine when recovered from surfaces. A cartridge that required no precise cutting of PSA paper prior to sampling or analysis was evaluated for use in PS‐MS for fentanyl screening. Recovery and detection of fentanyl from plastic sheeting was demonstrated with this cut‐free cartridge. The cut‐free cartridge showed somewhat less consistency and lower analyte signal than the standard cartridge, but performance was suitable for potential screening applications. In combining PSA surface sampling with PS‐MS for drug screening, both sampling and detection of fentanyl‐related compounds is simple, rapid, and low‐cost. [ABSTRACT FROM AUTHOR]

Classifying papers according to the fields of knowledge is critical to clearly understand the dynamics of scientific (sub)fields, their leading questions, and trends. Most studies rely on journal categories defined by popular databases such as WoS or Scopus, but some experts find that those categories may not correctly map the existing subfields nor identify the subfield of a specific article. This study addresses the classification problem using data from each paper (Abstract, Title, Keywords, and the KeyWords Plus) and the help of experts to identify the existing subfields and journals exclusive of each subfield. These "exclusive journals" are critical to obtain, through a pattern detection procedure that uses machine learning techniques (from software NVivo), a list of the frequent terms that are specific to each subfield. With that list of terms and with the help of optimization procedures, we can identify to which subfield each paper most likely belongs. This study can contribute to support scientific policy‐makers, funding, and research institutions—via more accurate academic performance evaluations—, to support editors in their tasks to redefine the scopes of journals, and to support popular databases in their processes of refining categories.

The United States Environmental Protection Agency (EPA) developed Toxic Release Inventory (TRI) using information submitted by different industries in the United States. This research examines the contaminants released by paper manufacturing industry in the United States and Ohio over time and what paper manufacturers are doing to diminish the quantities of chemical wastes generated, released to the environment, or managed by other means. It is understood that there is a reduction in the Risk-Screening Environmental Indicators (RSEI) scores from 2002 to 2014 in all the states, which can be related to the adaptation of recycling or reusing of the chemicals in various other manufacturing processes. The other significant observation inferred from the analysis is that the facilities in the states such as Wisconsin, Louisiana, South Carolina, Connecticut, and Pennsylvania based on the economic feasibility or recycling prospects, they are generating higher quantities of the selected chemical resulting in the higher RSEI scores respectively for the above-mentioned states. This article demonstrates the application of the risk-screening indicators model to a large database to analyze pollution data. © 2017 American Institute of Chemical Engineers Environ Prog, 36: 808-814, 2017 [ABSTRACT FROM AUTHOR]

How people pay is critically important to consumers and businesses alike. Many consumers are choosing to pay for goods and services from an increasing number of options. Tech‐savvy urbanites buy coffee by tapping their phone on a reader. Parents returning from a night out use peer‐to‐peer payment apps, such as Venmo, to pay the sitter. The recent explosion of financial innovations promises faster, more efficient, and cheaper transactions. These increasing digital payment options coincide with decreased number and volume of cash transactions. However, vulnerable populations face more constrained payment choices and often rely exclusively on cash. Without experience, devices, or acceptable credit histories, vulnerable populations may have little access to digital transactions. The advantages of falling digital costs and other benefits thus accrue to the digitally connected. At the same time, those who must transact in coins and paper money are likely to find their relative costs increasing. This paper highlights payment trends and the potential impact on vulnerable populations in the United States as we move toward a cashless society. This paper should stimulate discussions of public policy initiatives to mitigate digital payment issues for vulnerable people. [ABSTRACT FROM AUTHOR]

The article presents the effects of a waste paper product on soil phosphorus, carbon, and bulk density. Soil test values for phosphorus have increased due to the applications of manures to agricultural fields in the United States. Because of the application, there is a probability that phosphorus will be in the surface water. The effect will be the degradation of water quality. The danger of phosphorus transport to surface water may be lowered through the application of waste paper on soils with high soil test phosphorus. In Booneville, Arizona, a test was conducted to show the effects of adding waste paper product on soil phosphorus, carbon, and bulk density.

In this article, Maryland's non-legal-tender paper money emissions between 1765 and 1775 are reconstructed to determine quantities outstanding and redemption dates, providing a substantial correction to the literature. Over 80 per cent of this paper money's current market value was expected real asset present value and under 20 per cent was liquidity premium. It was primarily a real barter asset and not a fiat currency. The liquidity premium was positively related to the amount of paper money per capita in circulation. This paper money traded below face value due to time-discounting, rather than depreciation. Past scholars have simply confused depreciation with time-discounting. [ABSTRACT FROM AUTHOR]

Black women in the United States experience a higher maternal mortality rate compared to other racial groups. The maternal mortality rate among non‐Hispanic Black women is 3.5 times that of non‐Hispanic White women and is higher in the South compared to other regions. The majority of pregnancy‐related deaths in Black women are deemed to be preventable. Healthy People 2030 directs healthcare providers to advance health equity through societal efforts to address avoidable inequalities, historical and contemporary injustices, and the elimination of health and healthcare disparities. The Southern Nursing Research Society has put forward this position paper to provide recommendations to improve maternal health equity among Black women. Recommendations for nurses, multidisciplinary healthcare providers, policymakers, and researchers are discussed. [ABSTRACT FROM AUTHOR]

Hydroxychloroquine (HCQ) and chloroquine (CQ) are well‐established medications used in treating systemic lupus erythematosus and rheumatoid arthritis, as well as skin conditions such as cutaneous lupus erythematosus. In rare cases, arrhythmias and conduction system abnormalities, as well as cardiomyopathy, have been reported in association with HCQ/CQ use. Recently, however, the corrected QT interval (QTc)–prolonging potential of these medications, and risk of torsade de pointes (TdP) in particular, have been highlighted in the setting of their experimental use for COVID‐19 infection. This report was undertaken to summarize the current understanding of HCQ/CQ cardiac toxicity, describe QTc prolongation and TdP risks, and discuss areas of priority for future research. A working group of experts across rheumatology, cardiology, and dermatology performed a nonsystematic literature review and offered a consensus‐based expert opinion. Current data clearly indicate that HCQ and CQ are invaluable medications in the management of rheumatic and dermatologic diseases, but they are associated with QTc prolongation by directly affecting cardiac repolarization. Prescribing clinicians should be cognizant of this small effect, especially in patients taking additional medications that prolong the QTc interval. Long‐term use of HCQ/CQ may lead to a cardiomyopathy associated with arrhythmias and heart failure. Risk and benefit assessment should be considered prior to initiation of any medication, and both initial and ongoing risk–benefit assessments are important with regard to prescription of HCQ/CQ. While cardiac toxicity related to HCQ/CQ treatment of rheumatic diseases is rarely reported, it can be fatal. Awareness of the potential adverse cardiac effects of HCQ and CQ can increase the safe use of these medications. There is a clear need for additional research to allow better understanding of the cardiovascular risk and safety profile of these therapies used in the management of rheumatic and cutaneous diseases.

A study of pulp and paper mill workers indicated low risks of death from all causes (standardized mortality ratio (SMR) = 0.74) and all cancers (SMR = 0.81) compared with U.S. rates. The leukemia death rate in workers was not higher than the U.S. rate but was higher than the rate in county populations surrounding mills. Workers whose last jobs were in the finishing areas of the mills had an elevated SMR for liver cancer. An internal comparison of occupational characteristics indicated that workers employed in mills using other chemical pulping operations had significantly elevated mortality from all causes, all cancers, heart disease, lymphomas, and brain cancers. Lung cancer mortality was elevated in mills using kraft pulping. The internal comparisons confirmed the association between work in finishing and the risk of liver cancer. This study was designed to investigate whether pulp and paper mill workers have any risks that would indicate the need for studies detailing exposures.

Prior research on competitive dynamics has failed to offer tools to understand distorted patterns of competition that emerge from distinct institutional and historical contexts. Our analysis suggests that a joint effect of institutional rules, governance structures, and shared cognition plays a pivotal role in firm-level competitive behavior and capability development. We show how globally significant market positions can result from specific institutional arrangements between firms and governments, especially if coupled with interfirm contractual commitments. Our results call for more attention to these interfirm commitments that are built on formal rules and governmental support, but whose impact they yet exceed. Copyright © 2016 John Wiley & Sons, Ltd.

The article presents a case study of Northwestern Paper Co. From a single pulp and paper mill at the company's inception, Northwestern had expanded substantially over the years, opening additional pulp and paper mills across the United States. By the 1950s, the company was one of the largest U.S. producers of pulp and paper products. During the 1960s and 1970s, the company made a big push toward overseas expansion, particularly into Western Europe, where there was high demand for paper products. Market pulp was pulp sold on the open market, rather than being converted into paper at the company's own mills. It was shipped from the mill in bales of dry sheets. The early 1990s had proven difficult for Northwestern and other paper companies in the U.S. and Europe. Many of the industry's problems were attributable to the high level of excess production capacity. Industry growth during the 1980s led paper companies to invest heavily in new mills and paper machines. Starting in 1990, however, demand for paper products declined. In an attempt to absorb the high fixed costs associated with investments in plant and machinery, several firms in the industry had tried to maintain relatively high rates of plant capacity utilization.

As drug overdose deaths across the United States continue to rise, there is increasing interest in field testing of illicit substances. This work discusses a paper‐based analytical device (idPAD) that can run a library of 12 colorimetric tests at the same time, each detecting different chemical functional groups and materials found in illicit drugs, distractor substances, and cutting agents. The idPAD requires no electricity, costs less than $2 USD, and requires minimal training to operate. The results of the 12 tests form a color barcode which is "read" by comparison to standard images. The accuracy of the idPAD was assessed using samples of heroin, cocaine HCl, crack, and methamphetamine at concentrations of 25%–100% in a lactose matrix, as well as pure lactose. Based on 840 "reads" by three different users, the idPAD showed 95% sensitivity and 100% specificity for detecting these drugs; the most common error was mistaking cocaine HCl for crack or crack for cocaine HCl. In a second step, samples of heroin, cocaine, and methamphetamine (n = 30) and distractor substances (pharmaceuticals, cutting agents, and other illicit drugs, n = 64) were tested by two readers, yielding a sensitivity of 100% and specificity of 97%. Targeted substances were detected reliably at 55–180 μg/lane, and the idPAD was found to be stable for at least 3 months when stored at room temperature. The library approach used in the idPAD may provide the accuracy and robustness necessary for a presumptive field drug test. [ABSTRACT FROM AUTHOR]

In this paper, I draw on two childhood ethnographies to ask basic questions about the foundation of child writing. The first question is, where does writing come from in young children's lives? Answering this question will lead us to childhood play as the foundation of writing. The second question is, how do educators negotiate an inclusive, playful classroom culture in racially divisive and neoliberal times? This question will lead to a critical consideration of forming an inclusive culture in a racially and culturally diverse classroom. In this time of uniform, mandated curricula, rampant in the United States and elsewhere, and of the dismissive attitude towards play and towards childhood diversity (e.g., in race, culture and socioeconomic class), it is worth revisiting basic questions about the beginnings of writing in childhoods. The questions are relevant whether a child is writing on paper, screen, slate, or sand. [ABSTRACT FROM AUTHOR]
