Abstract Scientometric research often relies on large-scale bibliometric databases of academic journal articles. Long term and longitudinal research can be affected if the composition of a database varies over time, and text processing research can be affected if the percentage of articles with abstracts changes. This article therefore assesses changes in the magnitude of the coverage of a major citation index, Scopus, over 121 years from 1900. The results show sustained exponential growth from 1900, except for dips during both world wars, and with increased growth after 2004. Over the same period, the percentage of articles with 500+ character abstracts increased from 1% to 95%. The number of different journals in Scopus also increased exponentially, but slowing down from 2010, with the number of articles per journal being approximately constant until 1980, then tripling due to megajournals and online-only publishing. The breadth of Scopus, in terms of the number of narrow fields with substantial numbers of articles, simultaneously increased from one field having 1000 articles in 1945 to 308 in 2020. Scopus’s international character also radically changed from 68% of first authors from Germany and the USA in 1900 to just 17% in 2020, with China dominating (25%).

AbstractMany lessons in long-term cropping systems experiments are learned from practical experience. I have conducted large-scale, long-term, multidisciplinary dryland and irrigated cropping systems experiments with numerous colleagues at university and government research stations and in farmers' fields in the USA and in developing countries for 25 years. Several practical lessons learned through the years are outlined in this short commentary. While some of these lessons learned may be intrinsically obvious, results of many cropping systems experiments have not been published in scientific journals due to fatal flaws in experimental design, improper transitioning between phases of the experiment and many other reasons. Ongoing active support by stakeholders is critical to maintain funding for long-term cropping systems studies. Problems and unexpected challenges will occur, but scientists can often parlay these into opportunities for discovery and testing of new hypotheses. Better understanding and advancement of stable, profitable and sustainable cropping systems will be critical for feeding the world's projected 10 billion people by the mid-21st century.

Three Stages

Reactive leadership and crisis management have been synonymous for years. This flows from the belief that crisis is unpredictable and unexpected, which is simply not true. Crisis has its genesis in the values, beliefs, culture, or behavior of an organization which become incongruent with the milieu in which the organization operates. A leader, who is able to read the signals of looming crisis and understands how to harness the exigency brought on by the situation, can diminish the potential dangers and take full advantage of the resulting opportunities. This paper presents a generic crisis lifecycle as a representation of overall crisis. Since a crisis can be broken down into three unique phases, crisis lifecycles can be understood and utilized for the benefit of the organization. In the first phase of the lifecycle, the organization finds itself mired in a static phase which equates to a comfort zone. In this first phase leaders struggle when they attempt to introduce change or learning due to the organizations preference to avoid conflict and maintain stasis. When a crisis engulfs an organization then the stasis that envelops the organization evaporates and gives rise to the second phase or the disaster phase. The disaster phase often threatens the very existence of the organization. When the organization successfully eliminates the immediate organizational threat, the organization is able to enter the adjustive phase of the crisis lifecycle. In this third phase, the leader has the undivided attention of the organization and the underlying urgency to solve the issues that led to the crisis in the first place. Regrettably, many leaders don’t take advantage of this golden opportunity and push the organization back toward the status-quo which ensures that the crisis will return in force. The study of crisis leadership has become more important since the dawn of the new millennium because leaders in all areas face differing degrees of crisis in their daily work life. This emphasis on crisis leadership has spawned many books and academic journal articles which has resulted in a wide-ranging body of work from which we have divined the three stages of crisis and six strategies crucial for organizational success. These strategies are illustrated with examples of crisis leadership and how leaders saved their organization and tailored them for long-term significance.

Abstract Background Rising trends in takotsubo syndrome (TTS)-related complications warrant data to identify the rate, causes and predictors of readmission on a large scale. We conducted the first-ever meta-analysis to evaluate the pooled rate of short-term and long-term readmissions after index TTS admissions. Methods PubMed/Medline, EMBASE and SCOPUS databases were systematically reviewed to find studies through October 2019 reporting rates and causes of readmission following index TTS admissions. Random effects models were used to estimate pooled rates and causes of readmissions and I2 statistics were used to report inter-study heterogeneity. Results A total of 16 cohorts with 118,941 TTS index admissions (mean age 65–75 yrs; female >85%, median follow-up 272.5 days) revealed a 16.6% [95% CI-13.2%-20.3%, I2=99%] pooled rate of readmission. Short-term and long-term pooled readmission rates are displayed in Fig.1. The readmission rate was higher in cohorts with young patients (<70 vs. >70 yrs), smaller sample size (n<100 vs. n>100) and single-centres vs. multicentres. Studies published from the USA (16.4% vs. 14.9%) had a higher readmission rate as compared to Italy. The most frequent causes were cardiac (40.6%), respiratory (15.7%) and renal (7.0%). Among readmissions with cardiac diagnoses, heart failure was most common (40.1%). Conclusions This global meta-analysis revealed that the pooled rate of readmission following index TTS admissions was ∼17% and causes were mainly cardiac or respiratory.

Abstract Large-scale Lyngbya wollei (Cyanobacteria, Oscillatoriales) infestations are increasing throughout the USA and globally and causing significant obstruction of water resource uses. Decision makers and stakeholders encountering this nuisance organism often seek management options. Many approaches to L. wollei management may be ineffective or not applicable to specific field sites. Chemical control with United States Environmental Protection Agency registered algaecides has shown to be effective, although the specific formulation, concentration, and application frequency can all govern efficacy. This study summarizes results from a long-term and adaptive management program on extensive L. wollei infestations in three central Alabama, USA reservoirs (Lay Lake, Jordan Lake and Lake Mitchell) managed by Alabama Power Company. Multiple treatment strategies including numerous algaecides, combinations and addition of surfactants were used in attempts to control the nuisance cyanobacterium and preserve multiple beneficial functions of the resource. Ultimately, operational shift toward one technology, a double-chelated copper algaecide with surfactants and emulsifiers (Captain® XTR) resulted in more efficient and economical control. There were significant (P < 0.05) decreases in historic L. wollei acres requiring treatment through time on each reservoir. Throughout this study period, a 51.4, 88.1 and 94.7% percent decrease in total nuisance acres treated was realized on Lay Lake, Jordan Lake and Lake Mitchell, respectively. The large-scale and long-term dataset presented herein, covering multiple candidate treatment programs, provides valuable information to guide management decisions on other water resources impacted by L. wollei infestations.

AbstractThe large-scale coronal structures observed during the sporadically visible solar eclipses were compared with the numerically extrapolated field-line structures of coronal magnetic field. A characteristic relationship between the observed structures of coronal plasma and the magnetic field line configurations was determined. The long-term evolution of large scale coronal structures inferred from photospheric magnetic observations in the course of 11- and 22-year solar cycles is described.Some known parameters, such as the source surface radius, or coronal rotation rate are discussed and actually interpreted. A relation between the large-scale photospheric magnetic field evolution and the coronal structure rearrangement is demonstrated.

The utilization of an automated multitest laboratory as a data acquisition center and of a computer for trie data processing and analysis permits large scale preventive medical research previously not feasible. Normal test values are easily generated for the particular population studied. Long-term epidemiological research on large numbers of persons becomes practical. It is our belief that the advent of automation and computers has introduced a new era of preventive medicine.

This article examines fundamental questions of monetary policy in the context of challenges to the national security of Russia in connection with the imposition of economic sanctions by the US and the EU. It is proved that the policy of the Russian monetary authorities, particularly the Central Bank, artificially limiting the money supply in the domestic market and pandering to the export of capital, compounds the effects of economic sanctions and plunges the economy into depression. The article presents practical advice on the transition from external to domestic sources of long-term credit with the simultaneous adoption of measures to prevent capital flight.
