The concept of hip impingement and hip-preserving surgery has been appreciated in more detail since 2001 when a new surgical approach was reported and a hypothesis linking femoroacetabular impingement (FAI) with osteoarthritis was presented. Paralleling the introduction of hip arthroscopy, these events led to an increasing interest in the hip, and the number of publications has risen rapidly over the past 15 years, despite limited evidence levels and inconsistent methodology. Accordingly, etiology, diagnosis, prognosis, and the effects of treatment for FAI are still elusive due to a number of uncertainties and a lack of clear diagnostic criteria.Future research must focus on developing high-quality scientific studies, so thorough and reproducible methodology is needed. This review provides researchers, radiologists, and clinicians with a comprehensive approach to hip imaging with a focus on strategies to help guide the clinical diagnosis. Using evidence from current literature and knowledge from experienced clinicians, some of the imaging methodology challenges are deciphered.

Over the past two decades, research on the impacts of a diverse range of public policies and income inequality has seen rapid growth. Despite the large number of publications to date, there remain important lacunae in our understanding of how policy interventions might help to reduce income inequality. This paper aims to fill this void by providing a systematic literature review of 270 publications that examine four key policy areas: (1) tax policy, (2) social benefits, (3) labour market interventions, and (4) education policy. We describe patterns of empirical findings and implications drawn from the reviewed publications. The strengths and weaknesses of the existing literature are also discussed, along with potential future research avenues.

Abstract Background Although in all sexually reproducing organisms an individual has a mother and a father, non-genetic inheritance has been predominantly studied in mothers. Paternal effects have been far less frequently studied, until recently. In the last 5 years, research on environmentally induced paternal effects has grown rapidly in the number of publications and diversity of topics. Here, we provide an overview of this field using synthesis of evidence (systematic map) and influence (bibliometric analyses). Results We find that motivations for studies into paternal effects are diverse. For example, from the ecological and evolutionary perspective, paternal effects are of interest as facilitators of response to environmental change and mediators of extended heredity. Medical researchers track how paternal pre-fertilization exposures to factors, such as diet or trauma, influence offspring health. Toxicologists look at the effects of toxins. We compare how these three research guilds design experiments in relation to objects of their studies: fathers, mothers and offspring. We highlight examples of research gaps, which, in turn, lead to future avenues of research. Conclusions The literature on paternal effects is large and disparate. Our study helps in fostering connections between areas of knowledge that develop in parallel, but which could benefit from the lateral transfer of concepts and methods.

Background: The anterior cruciate ligament (ACL) is the most commonly operated ligament of the knee. Details on the top journals, universities, and authors on the topic would be helpful to identify the sources of information for clinical and research queries as well as to observe trends for future research and identify universities/authors of particular interest for training or to follow their research. Purpose: To consolidate information from PubMed on the ACL from 1979 to 2018, spanning 40 years. Study Design: Cross-sectional study. Methods: A search of the PubMed database was conducted for the ACL, and 18,696 articles published over the past 40 years were analyzed for further details. These details included the number of publications per year, top 10 journals publishing on the ACL, top 10 first authors publishing articles on the ACL, and number of articles published with specific keywords. Data were also sought from the Scopus database regarding the top universities and countries publishing on the ACL. The coauthorship of articles and co-occurrence of terms in titles were also analyzed using VOSviewer. Results: There was a steady increase in the yearly average number of publications from 1979 to 2018. The top journal and top author publishing on the ACL were The American Journal of Sports Medicine and Freddie H. Fu, respectively. The most articles published by a first author were by K. Donald Shelbourne. Time-based links of Dr Fu to other authors were represented as VOSviewer output. Most occurrences of specific keywords in the title were also studied and listed. The United States was the most published country, and 8 of the top 10 universities that published were from this country. Conclusion: There has been a steady increase in the number of articles published in PubMed since 1979. It appears that interest on the topic of the ACL has not decreased or stabilized but rather increased significantly over the past few years. This article quantifies the increased interest and could act as a baseline for future studies to compare.

Editing Process

Abstract National statistical institutes are responsible for publishing high quality statistical information on many different aspects of society. This task is complicated considerably by the fact that data collected by statistical offices often contain errors. The process of correcting errors is referred to as statistical data editing. For many years this has been a purely manual process, with people checking the collected data record by record and correcting them if necessary. For this reason the data editing process has been both expensive and time-consuming. This article sketches some of the important methodological developments aiming to improve the efficiency of the data editing process that have occurred during the past few decades. The article focuses on selective editing, which is based on an idea rather shocking for people working in the production of high-quality data: that it is not necessary to find and correct all errors. Instead of trying to correct all errors, it generally suffices to correct only those errors where data editing has substantial influence on publication figures. This overview article sketches the background of selective editing, describes the most usual form of selective editing up to now, and discusses the contributions to this special issue of the Journal of Official Statistics on selective editing. The article concludes with describing some possible directions for future research on selective editing and statistical data editing in general.

Insight Into

Research examining the influence of perceptions of organizational politics (POPs) is currently at a nexus—capable of recognizing its previous contributions but also with an eye toward the future. Scholars credit much of the maturation over the past 30 years to Ferris, Russ, and Fandt’s seminal model. Despite the ever-increasing number of publications attributed to this topic, and model, opportunities to bridge and expand the current research base remain plentiful. We begin this review by differentiating POPs from political behavior and constructs considered overlapping conceptually. We then describe the evolution of two models responsible for guiding POPs research and conclude our review by summarizing meta-analytic studies investigating antecedents and outcomes of POPs. Doing so allows us to identify gaps currently impeding development and to recommend relevant approaches to extend research. Following this review, we introduce event systems theory as a guiding framework for integrating and expanding the knowledge base. This structure allows scholars to recast POPs as a discrete phenomenon capable of being evaluated in terms of its novelty, disruption, and criticality. Theoretically, this approach allows for greater precision in identifying causes and consequences of POPs, and it provides insight into how such perceptions emerge and evolve. Last, we discuss future research opportunities intended to improve understanding of this pervasive phenomenon, and we encourage much-needed future research examining the dynamics of POPs in contemporary work settings.

A Over the past decade, we have been witnessing an exponential growth in the number of publications on Integrated Reporting, with the aim of exploring challenges, opportunities and implications of its adoption. Given the abundance of studies, which are often characterized by conflicting evidences, it can be complex to pinpoint all the seminal works already published: it raises the need to develop methodologies which can help to screen the existing literature and to detect the articles which contribute the most to the scientific research. However, little is known about structured approaches in accounting studies: thus, in order to extract the backbones of the research tradition on Integrated Reporting, in this paper we apply the dynamic literature review method called "Systematic Literature Network Analysis", which combines systematic literature review and bibliographic network analysis. Furthermore, our findings confirm how this methodology may be exploited as a research tool to support dynamic analyses for drawing agendas for future research in the accounting fields of study.

Face recognition using depth data has attracted increasing attention from both academia and industry in the past five years. Previous works show a huge performance gap between high-quality and low-quality depth data. Due to the lack of databases and reasonable evaluations on data quality, very few researchers have focused on boosting depth-based face recognition by enhancing data quality or feature representation. In the paper, we carefully collect a new database including high-quality 3D shapes, low-quality depth images and the corresponding color images of the faces of 902 subjects, which have long been missing in the area. With the database, we make a standard evaluation protocol and propose three strategies to train low-quality depth-based face recognition models with the help of high-quality depth data. Our training strategies could serve as baselines for future research, and their feasibility of boosting low-quality depth-based face recognition is validated by extensive experiments.

Mulberry (Morus spp.) is an evergreen tree belonging to the Moraceae family. The genus Morus has numerous described species, including Morus nigra, an important plant in agriculture and traditional cultures. The objective of this study was to conduct a scientometric research on the species M. nigra. Bibliographic data was been obtained from the Web of Science database considering two times periods. These analyzes showed that research involving M. nigra is concentrated in the areas of nutrition, pharmacology and agronomy science. Eastern countries and Brazil are the largest producers of knowledge about M. nigra. The research has shown different interests in recent decades, showing that the scientific knowledge produced about the species is associated with the objective for which the plant was used throughout history. There is a trend in the growth of publications focused on the potential antioxidant of M. nigra products. The articles had a greater impact factor in the past, however, a significant growth trend in research with M. nigra in the last three years, also suggested by the increase in the number of publications in the period. Understanding the publication standards assist in directing future research as well as in understanding the current panorama of research associated with the species.

During the past decade, an increase in the number of studies about dental erosion has been observed. The aim of the present study was to describe the current trends in published scientific articles related to dental erosion between 2011 and 2020. Data of the authors, year and language of publication were analyzed. A bibliometric analysis of the articles published in PubMed was conducted using the MeSH terms (dental erosion) and (tooth erosion) using the Boolean operator OR/AND. A sample of n = 1090 articles published during the past ten years (2011–2020) was obtained. The variables analyzed were the language of the article, the year of publishing, the number of authors, the affiliations of the first and last author and the relationship between them. The countries of origin of the first and last author were ranked according to the number of publications, led by Brazil, the UK, and the USA. During the analysis of the type of article, we observed that 79.4% of all publications were research articles. In recent years, a significant increase in research articles on dental erosion has been observed, especially in Brazil and the UK, with a high number of publications of translational articles in humans and cross-sectional observational studies. The main findings in this article will help researchers, academics and students to characterize scientific results regarding dental erosion, to evaluate management strategies and to identify important topics and issues that will help design future research.
