With the continuation of industrialization and urbanization, acid rain (AR) has aroused extensive concern because of its potential negative effects on ecosystems. However, analysis of the current status and development trends in AR research area has seldom been systematically studied. Therefore, we motivated to conduct a bibliometric analysis of AR publications (1900–2018) using HistCite and CiteSpace software programs. Compared to traditional reviews by experts, this study offers an alternative method to quantitatively analyze and visualize the development of AR field at a large time scale. The results indicated that the overall concern of AR research studies had increased from 1900 to 2018. The most productive country was the United States, while the institution with the most publications was Chinese Academy of Sciences. “Environmental Sciences” was the most popular subject category, Water, Air, and Soil Pollution was the dominant journal, and C.T. Driscoll was the most prominent author in AR field. There were three hotspots in the field of AR, including analyzing AR status and its control policies in Europe, the United States, and China in the past few decades, investigating the ecological consequences of AR on plant histological, physiological, and biochemical traits, as well as surface water and soil properties, and the model application for quantitatively assessing AR and its effects on terrestrial and aquatic ecosystems at regional scale. Further, “behavior”, “phosphorus”, “fractionation”, “soil acidification”, “corrosion”, “performance”, “recovery”, “rainwater”, “trace element”, and “surface water” have been emerging active topics in recent years. This study can help new researchers to find out the most relevant subject categories, countries, institutions, journals, authors, and articles, and identify research trends and frontiers in the field of AR.

Background: The prevalence of cancer has increased over time worldwide. Nevertheless, the number of deaths has been reduced during the past 2 decades. Thus, one-third of the cancer patients are users of complementary and alternative therapies, looking for other types of interventions. The main aim of the present study is to understand the current status of the research in integrative and complementary oncology. Three different aspects were analyzed: production trends, country collaboration, and leading research topics. Methods: The dataset was obtained from the documents indexed under the Integrative and Complementary Medicine category of the Web of Science database from 1976 to 2017. VOSviewer and SciMAT software were employed to perform the bibliometric analysis. Results: The Journal of Ethnopharmacology, China Medical University and the People’s Republic of China are the leading producers in the field. Regarding the collaboration, the United States and China present a close connection. The scientific community is focused on the following topics: apoptosis, breast cancer, oxidative stress, chemotherapy, and nuclear factor-Kappa-B (NF-Kappa-B). Conclusions: The present article shows potentially important information that allows understanding of the past, present, and future of research in integrative and complementary oncology. It is a useful evidence-based framework on which to base future research actions and academic directions.

<p>For several decades now the gun control literature in the United States has continued to produce conflicting accounts in regards to the availability of firearms on the U.S's high rate of homicide. This thesis proposes that this conflict is, in part, due to the implicit and continued influence of Wolfgang's (1958) 'weapon substitution hypothesis'. Wolfgang's hypothesis proposes that the intentions of an assailant, whether they be to kill or injure, determined the weapon selected. Since guns are recognised as being highly lethal, all assailants who use such weapons were believed by Wolfgang to have been highly determined to kill. Among other negative effects, it is argued that Wolfgang's hypothesis introduced a mind-set to this controversial research area that has continued to influence the opinions of academics from both sides of the debate. This mind-set revolves around the consensually held belief that if a firearm assailant is believed to have been determined to kill then they would have been capable of killing in the absence of firearms. Importantly, this belief implies that the best possible predictor of lethal weapon substitution is if a firearm assailant is determined to kill. This is unlikely to be true.  Mischel (1968: 135) has argued: 'A person's relevant past behaviours tend to be the best predictors of his future behaviour in similar situations.' After adapting Mischel's logic to fit the weapon substitution debate, the following predictor was produced. The best possible predictor of lethal weapon substitution to non-firearm weapons is whether people who had killed with firearms were as experienced at killing victims with non-firearm weapons as assailants who had actually killed with such weapons. This predictor was further developed into a more workable methodology that was capable of testing the validity of both Wolfgang's hypothesis and the consensually held belief it initiated. This methodology involved a comparison of the previous serious to fatal violent non-firearm convictions between those most likely to be determined firearm and knife killers. It was discovered that only 2.94 percent of those most likely to be determined firearm assailants and 25.23 percent of those most likely to be determined knife assailants had previous convictions for serious to fatal non-firearm assaults. This result was statistically significant to the p< 0.005 (Z score=2.84). After eliminating all other possible explanations for these results it was concluded that, in conflict with both Wolfgang's hypothesis and the consensually held belief, not all determined firearm assailants are likely to be capable of lethal weapon substitution. Furthermore, if some proportion of determined firearm assailants are unlikely to be capable of lethal weapon substitution, then those not so determined are likely to be even less capable. Therefore, it was concluded that inhibiting all potential firearm assailants from accessing guns would be likely to reduce the overall rate of homicide. However, this thesis was limited in being able to apply this conclusion to the United States because it was based on a New Zealand population. Nevertheless, it is argued that the perpetuation of the consensually held belief has inhibited the best possible predictor of lethal weapon substitution from being applied to a research area where prediction is of paramount importance. When the best possible predictor of lethal weapon substitution has not previously been applied, it therefore becomes more understandable why this research area is plagued by such controversy.</p>

The current study aims to analyse the trend in yeast research within the domain of biopharmaceutical sciences. Bibliographic information of the 1,000 most cited publications on yeast research in biopharmaceutical science was retrieved from the Scopus database. The data was then analysed by using bibliometric approaches. The data indicated a steady increase in publication numbers. The United States, Japan and China were among the highest research output countries. A total of 25 top core journals were identified. The keywords with the highest frequency included production, study and activity. To conclude, the current bibliometric analysis provides information that may be useful in locating research hot spots and gaps in the research area of yeast in biopharmaceutical science.

Petroleum contaminated soils have become a great concern worldwide. Bioremediation has been widely recognized as one of the most promising technologies and has played an important role in solving the issues of petroleum contaminated soils. In this study, a bibliometric analysis using VOSviewer based on Web of Science data was conducted to provide an overview on the field of bioremediation of petroleum contaminated soils. A total of 7575 articles were analyzed on various aspects of the publication characteristics, such as publication output, countries, institutions, journals, highly cited papers, and keywords. An evaluating indicator, h-index, was applied to characterize the publications. The pace of publishing in this field increased steadily over last 20 years. China accounted for the most publications (1476), followed by the United States (1032). The United States had the highest h-index (86) and also played a central role in the collaboration network among the most productive countries. The Chinese Academy of Sciences was the institution with the largest number of papers (347) and cooperative relations (52). Chemosphere was the most productive journal (360). Our findings indicate that the influence of developing countries has increased over the years, and researchers tend to publish articles in high-quality journals. At present, mainstream research is centered on biostimulation, bioaugmentation, and biosurfactant application. Combined pollution of petroleum hydrocarbons and heavy metals, microbial diversity monitoring, biosurfactant application, and biological combined remediation technology are considered future research hotspots.

Abstract. During the last decades, several studies have been conducted on the effectiveness of sexual abuse prevention programs implemented in different countries. In this article, we present a review of 70 studies (1981–2017) evaluating prevention programs, conducted mostly in the United States and Canada, although with a considerable presence also in other countries, such as New Zealand and the United Kingdom. The results of these studies, in general, are very promising and encourage us to continue this type of intervention, almost unanimously confirming its effectiveness. Prevention programs encourage children and adolescents to report the abuse experienced and they may help to reduce the trauma of sexual abuse if there are victims among the participants. We also found that some evaluations have not considered the possible negative effects of this type of programs in the event that they are applied inappropriately. Finally, we present some methodological considerations as critical analysis to this type of evaluations.
