Numerous students suffer from academic procrastination; it is a common problem and phenomenon in academic settings. Many previous researchers have analyzed its relationships with other factors, such as self-regulation and academic success. This paper aims to provide a full outline of academic procrastination and explore the current hot spots and trends. Bibliometrix and VOSviewer were used to conduct quantitative analysis. The data was collected from the Web of Science core collection database, which contains 1,240 articles from the years 1938 to 2021. The analysis shows that the publication of articles on academic procrastination has been rapidly increasing since 1993. In terms of the most influential countries and institutions, the United states took a prominent lead among all countries, and the most productive institutions in this area were the University of Washington and University of California, Los Angeles. By analyzing the authors, we see that most authors like working with a few collaborators, leading to main groups of authors, such as Murat Balkis and June J. Pilcher. The most frequently cited author was Esther D. Rothblum. Based on the co-citation journals network, Personality and Individual Differences was the prolific and influential journal referring to the number of citations and articles it received. The VOSviewer tool identified the hot spots of academic procrastination, which were mainly distributed as follows: (a) procrastination, (b) academic procrastination, (c) self-regulation, (d) academic performance, and (e) motivation. Therefore, this paper is helpful for scholars and practitioners to know the trend of academic procrastination research comprehensively.

The Impact

OBJECT Recent works have assessed academic output across neurosurgical programs using various analyses of accumulated citations as a proxy for academic activity and productivity. These assessments have emphasized North American neurosurgical training centers and have largely excluded centers outside the United States. Because of the long tradition and level of academic activity in neurosurgery at the University of Toronto, the authors sought to compare that program's publication and citation metrics with those of established programs in the US as documented in the literature. So as to not rely on historical achievements that may be of less relevance, they focused on recent works, that is, those published in the most recent complete 5-year period. METHODS The authors sought to make their data comparable to existing published data from other programs. To this end, they compiled a list of published papers by neurosurgical faculty at the University of Toronto for the period from 2009 through 2013 using the Scopus database. Individual author names were disambiguated; the total numbers of papers and citations were compiled on a yearly basis. They computed a number of indices, including the ih(5)-index (i.e., the number of citations the papers received over a 5-year period), the summed h-index of the current faculty over time, and a number of secondary measures, including the ig(5), ie(5), and i10(5)-indices. They also determined the impact of individual authors in driving the results using Gini coefficients. To address the issue of author ambiguity, which can be problematic in multicenter bibliometric analyses, they have provided a source dataset used to determine the ih(5) index for the Toronto program. RESULTS The University of Toronto Neurosurgery Program had approximately 29 full-time surgically active faculty per year (not including nonneurosurgical faculty) in the 5-year period from 2009 to 2013. These faculty published a total of 1217 papers in these 5 years. The total number of citations from these papers was 13,434. The ih(5)-index at the University of Toronto was 50. CONCLUSIONS On the basis of comparison with published bibliometric data of US programs, the University of Toronto ranks first in terms of number of publications, number of citations, and ih(5)-index among neurosurgical programs in North America and most likely in the world.

Research on melatonin remains one of the major hot spots in the field of disease treatment, but relevant data are numerous. The purpose of this study was to quantitatively and qualitatively analyze the progress of melatonin research through the method of bibliometrics and to predict hot spots and trends in melatonin research. This study retrieved all the studies on melatonin from 2000 to 2019 in the Web of Science and PubMed and analysed the publishing trends in the literature on a bibliometric online analysis platform and CiteSpace software. The research results were also visually analysed to summarize melatonin research hot spots through gCLUTO and pubMR. The study retrieved a total of 20,351 publications, of which the number of US publications ranked first, accounting for 21.46%, with the greatest impact (centrality = 0.31). The University of Texas Health Science Center at San Antonio and Harvard University had the highest average number of citations at 43.19 and 33.96, respectively. Journal of Pineal Research had the highest average number of citations in 2,993 journals. Professor Reiter made the largest contribution to this area. We further analysed 100 highly cited articles for clinical applications and ongoing related clinical drug trials based on the first hot spot. We systematically analysed melatonin for nearly 20 years while predicting the main research trends in the future, which may provide new directions and ideas for melatonin research. The structure and normal physiological functions of melatonin have been intensively studied in the past few years. And clinical application research and target of melatonin treatment for different diseases and target-based drug design will certainly become the focus of melatonin research.

IntroductionInvestigations of auditory brainstem implants (ABIs) in children started around 2012 in the United States. The team at the University of Southern California-Caruso Family Center for Childhood Communication began seeing children, implanted abroad, in 2006. ABIs are indicated for children who cannot benefit from cochlear implants (CIs). The habilitation and educational needs of children with ABIs versus CIs differ.PurposeThis document provides information professionals can use when implementing habilitation programs for children with ABIs.MethodThe University of Southern California-Caruso Family Center for Childhood Communication, as part of the Los Angeles Pediatric ABI team, is conducting an ABI safety and feasibility clinical trial. This article shares experiences from the viewpoint of a multidisciplinary team. The article provides background knowledge, an outcomes review, and considerations to guide ABI intervention.ResultsABIs and CIs differ in the acoustic information they provide. Outcome studies suggest progress is slow with ABIs but that children can develop some auditory or spoken language skills. The children require highly supportive learning experiences. Visual communication support remains important. The considerations outlined reflect the children's need for explicit instruction.ConclusionsWhen serving children with ABIs, therapists must apply their broad knowledge about working with children with hearing loss, tempering that knowledge, and recognizing that auditory access and progress differ with ABIs compared to CIs. Educational and program placement decisions may require unconventional thinking.

AbstractDuring and following a disaster caused by a natural event, human populations are thought to be at greater risk of psychological morbidity and mortality directly attributable to increased, disaster-induced stress. Drawing both on the research of others and that conducted at the Center for Public Health and Disaster Relief of the University of California-Los Angeles (UCLA) following California earthquakes, this paper examines the extent to which research evidence supports these assumptions. Following a brief history of disaster research in the United States, the response of persons at the time of an earthquake was examined with particular attention to psychological morbidity; the number of deaths that can be attributed to cardiovascular events and suicides; and the extent to which and by whom, health services are used following an earthquake. The implications of research findings for practitioners in the field are discussed.

The Impact

The activity analysis of a scientific journal is relevant to know the evolution of its characteristics over time. In this paper, results of a bibliometric study of the Revista de Biología Tropical/International Journal of Tropical Biology and Conservation (Costa Rica) are presented. The goal of this study was to describe the main characteristics of its scientific production, and analyze its level of collaboration and its impact between the years 2003-2012. Data was derived from the Web of Science (Thomson-Reuters), and the relationship among authors and coauthors, institutions and countries, and their links with the citations received were analyzed for that period. Descriptive statistics about production (number of documents per year, institution and country), collaboration (authorship index, collaboration among institutions and countries) and impact (IF, position in JCR and number of citations received) were collected. Results showed that the journal has published 1 473 papers in this period, in similar proportions English and Spanish. Mexico, Costa Rica, Venezuela and Colombia are the most common countries of origin, with the Universidad of Costa Rica, Universidad Autónoma de Mexico and the University of Puerto Rico as the most common leader institutions. Collaboration between authors, institutions and countries has shown an increasing trend over the last decade. The co-author index was 3.07 per document, 63 % of publications included 2 or more institutions, and 22 % of the papers were product of international collaboration. The most common collaboration link was between Costa Rica and the United States of America. The impact factor has been oscillating during this last decade, reaching a maximum in 2012 (IF JCR = 0.553). Besides, 10 % of the most cited papers concentrated half of the citations received by the journal, and have a very high number of citations, compared with the journal mean. The main countries that cite the journal were USA, Brazil, Mexico, Argentina and Costa Rica. Data showed an increasing collaboration between authors, institutions and countries, and a direct relationship between the increase of this collaboration and the received impact.

It is not possible to capture all the depth that composes Dr. Linda Liau: chair of the Neurosurgery Department at the University of California, Los Angeles; second woman to chair a neurosurgery program in the United States; first woman to chair the American Board of Neurological Surgery; first woman president of the Western Neurosurgical Society; and one of only a handful of neurosurgeons elected to the National Academy of Medicine. Her childhood and family history alone could fascinate several chapters of her life’s biography. Nonetheless, this brief biography hopes to capture the challenges, triumphs, cultural norms, and spirit that have shaped Dr. Liau’s experience as a successful leader, scientist, and neurosurgeon. This is a rare story. It describes the rise of not only an immigrant within neurosurgery—not unlike other giants in the field, Drs. Robert Spetzler, Jacques Marcos, Ossama Al-Mefty, and a handful of other contemporaries—but also another type of minority in neurosurgery: a woman.

The Impact

Each year, the United States resettles more refugees than any other country in the world. These students are placed into foreign learning environments where they are forced to adapt to new academic settings while also adjusting to a new culture. Often times, these students are escaping a violent past and are placed with teachers who have limited training in dealing with such issues. This article provides school leaders with intentional implementation strategies within a three-tiered framework that can be used to guide districts towards a more comprehensive and culturally responsive educational setting. Future research would be beneficial in the areas of students’ feelings of school belonging, selfawareness, nationality equating to academic achievement, and the impact entry age has on academic success.
