Accessibility and Types of Online Sources Cited in Scholarly Biomedical Journal in Iran

One type of frequently used references in scientific papers is online references. The aim of this study is to study the prevalence, accessibility and types of online sources in biomedical journals in Iran from 2010 to 2012. We analyzed online references cited in 401 articles from 21 scientific journals indexed in PubMed, Web of Science, and Scopus. Findings revealed that only 73 papers (18.2%) had cited online sources in their references. of 186 online citations, 72 (38.7%) citations were accessible, and the URLs to 114 citations did not work (61.3%). The majority of unreachable citations were unstable citations (32.3%). Most online sources (62%) were cited in “Iranian Journal of Public Health”. An increase in the number of online citations was observed over the studied years. The study indicated that the rate of online citations is low in the studied journals, and most online citations were unreachable. The lack of clear guidelines in citing online sources seemed to be a major reason for the inaccessibility of online citations

The Availability and Persistence of Web Citations in Iranian LIS Journals (2006-2010)

To discover the current situation and characteristics of Web citations accessibility, the present study examined the accessibility of 4,253 Web citations in six key Iranian LIS journals published from 2006 to 2010. The proportion percentage of Web citations increased from 11% in 2006 to 30% in 2010. The most widely cited top level domains in URLs include the .edu and .org with respectively 37% and 23%. This study provides further evidence that organizations Websites have become increasingly vulnerable to URL decay .The results show that only 3,467 Web citations remain accessible in 2011, of which 71% allowed easy and long-term access to author information contained in URLs. Long time inaccessibility to author information was shown to be mostly from URLs that returned the 404 error and also the URLs that had gone through an information update. A 4-year half-life was estimated for Iran’s LIS Publications. The results suggest that the decay of URLs is a grave problem in the publications of Iran’s LIS researchers and cannot be overlooked. These authors need to gain the necessary knowledge about using Web citations as major sources of information for their publications

Breaking Down Link Rot: The Chesapeake Project Legal Information Archive’s Examination of URL Stability

Ms. Rhodes explores URL stability, measured by the prevalence of link rot over a three-year period, among the original URLs for law- and policy-related materials published to the web and archived though the Chesapeake Project, a collaborative digital preservation initiative under way in the law library community. The results demonstrate a significant increase in link rot over time in materials originally published to seemingly stable organization, government, and state web sites

Machine Learning Applications in Studying Mental Health Among Immigrants and Racial and Ethnic Minorities: A Systematic Review

Background: The use of machine learning (ML) in mental health (MH) research is increasing, especially as new, more complex data types become available to analyze. By systematically examining the published literature, this review aims to uncover potential gaps in the current use of ML to study MH in vulnerable populations of immigrants, refugees, migrants, and racial and ethnic minorities. Methods: In this systematic review, we queried Google Scholar for ML-related terms, MH-related terms, and a population of a focus search term strung together with Boolean operators. Backward reference searching was also conducted. Included peer-reviewed studies reported using a method or application of ML in an MH context and focused on the populations of interest. We did not have date cutoffs. Publications were excluded if they were narrative or did not exclusively focus on a minority population from the respective country. Data including study context, the focus of mental healthcare, sample, data type, type of ML algorithm used, and algorithm performance was extracted from each. Results: Our search strategies resulted in 67,410 listed articles from Google Scholar. Ultimately, 12 were included. All the articles were published within the last 6 years, and half of them studied populations within the US. Most reviewed studies used supervised learning to explain or predict MH outcomes. Some publications used up to 16 models to determine the best predictive power. Almost half of the included publications did not discuss their cross-validation method. Conclusions: The included studies provide proof-of-concept for the potential use of ML algorithms to address MH concerns in these special populations, few as they may be. Our systematic review finds that the clinical application of these models for classifying and predicting MH disorders is still under development

The Current Status of Professional Journals in Dental and Oral Health from Arabic-speaking Countries

The Arabic‐speaking region is disproportionately affected by oral health conditions compared with industrialized nations. The World Health Organization recommends oral health integration into chronic disease programs in middle‐ to low‐income countries. This article evaluates availability of peer‐reviewed dental and oral health publications in the Arabic‐speaking region. Dental journals were identified through (i) PubMed NLM Catalog Journals; (ii) Scopus; (iii) Google Scholar; (iv) Science Direct; (v) the Index Medicus for the Eastern Mediterranean Regional Office; and (vi) Iraqi Academic Scientific Journals database. Each journal site was evaluated for aim/scope, publication period, activity status, format, and language. The search returned 28 dental and oral health professional journals that fit the study parameters; all were tabled and described by evaluation criteria. Language is a key element that emerged within the sample. The prevalence of online formats may inhibit community‐level practitioners from accessing regionally and culturally congruent dental research

An Analysis of the Availability and Persistence of Web Citations in Iranian LIS Journals

To discover the current situation and characteristics of web citations accessibility, the present study examined the accessibility of 4,253 web citations in six key Iranian LIS journals published from 2006 to 2010. The proportion percentage of web citations increased from 11% in 2006 to 30% in 2010. The most widely cited top level domains in URLs include the .edu and .org with respectively 37% and 23%. This study provides further evidence that organizations websites have become increasingly vulnerable to URL decay. The results show that only 3467 web citations remain accessible in 2011, of which 71% allowed easy and long-term access to the authors’ information intended in URLs. Long time inaccessibility to the authors’ intended information was shown to be mostly from URLs that returned the 404 error and also the URLs that had gone through information update. An about 4 year half-life was estimated for Iran’s LIS Publications. Ultimately, the results suggest that the decay of URLs is a grave problem in the publication of Iran’s LIS researchers and cannot be overlooked. These authors need to gain the necessary knowledge about using web citations as major sources of information for their publications

Availability and Preservation of Scholarly Digital Resources

The dynamic, decentralized world-wide-web has become an essential part of scientific research and communication, representing a relatively new medium for the conveyance of scientific thought and discovery. Researchers create thousands of web sites every year to share software, data and services. Unlike books and journals, however, the preservation systems are not yet mature. This carries implications that go to the core of science: the ability to examine another\u27s sources to understand and reproduce their work. These valuable resources have been documented as disappearing over time in several subject areas. This dissertation examines the problem by performing a crossdisciplinary investigation, testing the effectiveness of existing remedies and introducing new ones. As part of the investigation, 14,489 unique web pages found in the abstracts within Thomson Reuters’ Web of Science citation index were accessed. The median lifespan of these web pages was found to be 9.3 years with 62% of them being archived. Survival analysis and logistic regression identified significant predictors of URL lifespan and included the year a URL was published, the number of times it was cited, its depth as well as its domain. Statistical analysis revealed biases in current static web-page solutions
