Auditing the representation of migrants in image web search results

Search engines serve as information gatekeepers on a multitude of topics that are prone to gender, ethnicity, and race misrepresentations. In this paper, we specifically look at the image search representation of migrant population groups that are often subjected to discrimination and biased representation in mainstream media, increasingly so with the rise of right-wing populist actors in the Western countries. Using multiple (n = 200) virtual agents to simulate human browsing behavior in a controlled environment, we collect image search results related to various terms referring to migrants (e.g., expats, immigrants, and refugees, seven queries in English and German used in total) from the six most popular search engines. Then, with the aid of manual coding, we investigate which features are used to represent these groups and whether the representations are subjected to bias. Our findings indicate that search engines reproduce ethnic and gender biases common for mainstream media representations of different subgroups of migrant population. For instance, migrant representations tend to be highly racialized, and female migrants as well as migrants at work tend to be underrepresented in the results. Our findings highlight the need for further algorithmic impact auditing studies in the context of representation of potentially vulnerable groups in web search results.

Rayleigh quotient with bolzano booster for faster convergence of dominant eigenvalues

Computation ranking algorithms are widely used in several informatics fields. One of them is the PageRank algorithm, recognized as the most popular search engine globally. Many researchers have improvised the ranking algorithm in order to get better results. Recent research using Rayleigh Quotient to speed up PageRank can guarantee the convergence of the dominant eigenvalues as a key value for stopping computation. Bolzano's method has a convergence character on a linear function by dividing an interval into two intervals for better convergence. This research aims to implant the Bolzano algorithm into Rayleigh for faster computation. This research produces an algorithm that has been tested and validated by mathematicians, which shows an optimization speed of a maximum 7.08% compared to the sole Rayleigh approach. Analysis of computation results using statistics software shows that the degree of the curve of the new algorithm, which is Rayleigh with Bolzano booster (RB), is positive and more significant than the original method. In other words, the linear function will always be faster in the subsequent computation than the previous method.

Brain death and the internet: evaluating the readability and quality of online health information.

Brain death has been accepted medically and legally as biological death. Nevertheless, it is a difficult concept for the public to understand, resulting in a reliance on online resources for clarity. When the information is inaccurate, misleading, or elusive, the internet could have adverse effects on the public's decision-making. Here we aimed to assess the quality and readability of information regarding brain death on the internet. The five most popular search engines were queried using the keyword 'brain death' and the top 30 websites of each search engine were evaluated. Authorship was classified as medical or public. Gunning Fog Index (GFI) and Flesch Reading Ease Score (FRES) were calculated to analyze readability. The LIDA was used to assess quality. The overall LIDA score was 60,3%, with a mean score of 60.8%, 60.7%, and 59.3% for accessibility, usability, and reliability, respectively, indicating a moderate level. The accessibility of medical websites (P=0.037) and the reliability of public websites (P=0.031) were found to be significantly weaker. The average FRES was 41.6±14.6 rated as difficult, and the mean GFI was 15.7±3.4, indicating mean readability at "difficult, grade >10". Online health information on brain death exceeds the National Institutes of Health recommended reading levels. Our results emphasize the need to establish quality guidelines to improve the comprehensiveness of health website content. Brain death is still a contentious topic; therefore, reliable, and easy-to-read online educational materials can help public understand the concept of brain death and potentially improve the transplant rate.

Internet Search Results for Older Adult Physical Activity Guidelines: Scoping Review.

BackgroundOlder adults seek health-related information through casual internet searches. Yet, researchers focus on peer-reviewed journals and conference presentations as primary dissemination strategies. Representatives of mass media are alerted (passive diffusion) of new studies or recommendations, but the veracity of the information shared is not often analyzed, and when it is, the analysis is often not comprehensive. However, most older adults do not have access to peer-reviewed journal articles or paid subscription services for more reputable media outlets.ObjectiveWe aimed to determine what information was readily available (ie, open access) to older adults who may casually search the internet for physical activity recommendations.MethodsWe performed a 6-part scoping review to determine the research question and available evidence, and extract data within open-access top hits using popular online search engines. Results were categorized by a dissemination model that has categories of sources, channels, audience, and messages.ResultsAfter the iterative search process, 92 unique articles were included and coded. Only 5 (5%) cited physical activity guidelines, and most were coded as promoting healthy aging (82/92, 89%) and positive framing (84/92, 91%). Most articles were posed as educational, but the authors’ credentials were rarely reported (ie, 22% of the time). Muscle strengthening and balance components of the physical activity guidelines for older adults were rarely reported (72/92, 78% and 80/92, 87%, respectively) or inaccurately reported (3/92, 3% and 3/92, 3%, respectively).ConclusionsInconsistent messages lead to mistrust of science and public health representatives. This work highlights the lack of evidence within existing open-access resources. Further efforts are needed to ensure evidence-based public health messages are in the sources and channels older adults are using to inform their knowledge and behaviors.

Salt marsh restoration: an overview of techniques and success indicators.

Coastal wetlands including salt marshes are among the most productive ecosystems on Earth. They are known for improving the quality of coastal water and provisioning coastal fisheries. However, this ecosystem is under potential threat due to urban coastal land reclamation, limited sediment supply, increased nutrient/eutrophication, and sea level rise. Therefore, restoration efforts to protect the degraded salt marsh habitat are considerably increasing worldwide. In this paper, we present an overview of salt marsh restoration techniques and success indicators. Published scientific literature in English language was collected by searching the most relevant keywords from popular search engines, namely, Google Scholar, Scopus, and Mendeley to get the information about salt marsh restoration techniques and success indicators. This study comprehensively reviewed data from 78 peer-reviewed papers. Results indicated that much of the salt marsh was restored through assisted abiotic strategies (e.g., recovery of tidal exchange, managed realignment, and sediment level amendment). A total of 214 indicators were found, spanning over six major ecological attributes such as structural diversity, ecosystem functions, physical conditions, species composition, external exchange, and absence of threat. Author keywords analysis revealed several hotspots for recent research (e.g., 16s rRNA, fungi, microbial communities, carbon accumulation, and blue carbon). This paper proposes a model for restoring degraded salt marsh, as well as tracking their success.The information presented here will assist the marine ecosystem restoration practitioners in getting a comprehensive understanding of salt marsh restoration success evaluation.

Laparoscopic Cholecystectomy: Evaluation of Web-Based Information.

IntroductionLaparoscopic cholecystectomy (LC), the gold standard treatment for symptomatic gallstone disease, is the most common procedure performed by general surgeons worldwide. The internet remains to be a popular source of medical information. Our aim was to evaluate the quality and readability of information available on the web for patients undergoing LC and to compare the information provided by the National Health Service (NHS) and non-NHS websites. MethodsWe searched for the keywords ‘laparoscopic cholecystectomy’ using the three most popular search engines (Google, Yahoo and MSN) and looked at the first 50 websites only. The readability of each document was assessed using the Flesch Reading Ease (FRE) score. We checked Health on the Net Foundation Code of Conduct (HONcode) certification status, whether the sites had been checked by an expert and when the information was last updated.ResultsFifty-five of the possible 150 sites were analysed thus excluding repetitions (n=65), irrelevant content (n=26) or inaccessible links (n=3). Only seven of those were HONcode-certified. The mean FRE score was 46 (range 0-68, SD=16.13). There were 13 NHS sites and 42 non-NHS sites. The mean FRE score for the NHS sites was significantly better compared to the non-NHS sites [58.31 (SD=5.01) vs 42.21 (SD=16.35); p=0.001]. Fifty-four per cent (54%) of the analysed websites had been checked by a medical expert and 22% were updated within the last year.ConclusionsThis study highlights the poor quality and readability of information on medical websites. The information provided by NHS sites have significantly better readability compared to non-NHS sites.

Assessing the Accuracy, Quality, and Readability of Online Patient Resources on Tarsal Coalition

Category:Other; HindfootIntroduction/Purpose:The internet is an inexpensive and convenient source for health information. However, without regulation, the quality and accuracy of the information is unknown. Tarsal coalition is a common cause of pediatric foot pain and disability. We hypothesized that the online patient information on tarsal coalition is of low accuracy, low quality, and of poor readability. Additionally, we hypothesized that sources found on the first search page were of higher quality, greater accuracy, and more readable.Methods:A cross-sectional review of the internet was performed using the term 'tarsal coalition' on the 3 most popular search engines. Unique sites were categorized based on authorship and search result order. Websites were evaluated using a novel content score based on the AAOS OrthoInfo site on tarsal coalition (max score: 20), JAMA Benchmark and DISCERN scores for quality, and Flesch-Kincaid Grade Level (FKGL) and Flesch Reading Ease (FRE) for readability.Results:A total of 47 unique websites were evaluated. They ranged from professional organization/society websites to websites for individual practices and professional blogs. The average content score was 13.1 (range: 4-20). The average DISCRN score was 34.2 (range: 19-57.5). We did find a positive correlation between the content score and DISCERN scores of the included resources (p=0.04). The average 11.4 (range 8.5-15.5). Only 2 of the websites (4%) were written at or below an 8th grade reading level, which has been documented as the average reading level of the general population in the United States. Websites that were authored by physicians had greater DISCRN and readability scores compared to academic and private practice websites (DISCERN 40.4 vs 32.3 (p=0.001) and 31.7 (p=0.01), respectively, FKGL 13.0 vs 10.4 (p=0.002) and 11.1 (p=0.03), respectively, FRE 31.5 vs 48.7 (p=0.0001) and 45.2 (p=0.025), respectively).Conclusion:Online patient resources on tarsal coalition are of low quality, inaccurate, and too complex for the average reader. Physician authored websites may serve as better resources compared to academic or private practice sites. Physicians should caution patients using the internet for information on tarsal coalition.

EFFICIENCY INCREASING OF INFORMATION SEARCH ON A GIVEN TOPIC ON THE INTERNET

The article discusses the ways to overcome the difficulties associated with surfing the Internet for certain information. Many users are not able to explicitly make up a search request according to their information needs, and their search is often limited to haphazard use of several most popular search engines. Most search engine research is technical. At the same time, in recent years more and more researchers have paid the attention to the study of information search issues in the global network. These studies are at the junction of computer science and psychology. It focuses on information behavior and user needs, cognitive factors and information practices of users. The article examines the previously applied conceptual models of information retrieval, formulates a conceptual model of information retrieval on a given topic. The main properties of user interaction with search engines and factors that should be taken into account are considered. The procedure for information search and analysis in universal and scientific search systems is described. The description of experimental testing of the proposed conceptual search model is provided. The article proposes a new conceptual model of search in universal and scientific search engines. This model contributes to the formation of a metacognitive search strategy. In addition, a generalized indicator of the efficiency of information retrieval using such a model is proposed. The proposed conceptual search model can be applied in the educational process. In particular, the article provides an example of students’ use of the elements of the formed metacognitive strategy when doing Bachelor degree paper research.

Ayurveda for management of migraine: A narrative review of clinical evidence.

Migraine is a primary headache disorder characterized by recurrent attacks. The economic and societal burden of migraine is substantial, affecting patients' quality of life in terms of work, social activities, and family life. This article attempts to review the available literature for clinical evidence of Ayurveda in the management of migraines. We performed a literature search from January 2000 to July 2020 on popular search engines such as Pub Med, Google Scholar, and AYUSH Research Portal using the keywords "Complementary and Alternative Medicine (CAM) and Migraine", "Ayurveda and Migraine" and "Panchakarma and Migraine". The selection criteria involved published clinical trials, including pilot studies, whereas review articles, concept papers, letters to the editor, and studies published in languages other than English were excluded. Out of 77 studies that were screened, 12 articles that satisfied the selection criteria consisted of six Randomized controlled Trials (RCTs), five non-RCTs, and one pilot study. Among them, ten studies used polyherbal and Herbo mineral formulations, two studies contained no oral medications, three trials utilized external therapies, and ten studies used panchakarma procedures. Eleven studies found Ayurveda to be clinically beneficial as monotherapy, while one study demonstrated the usefulness of Ayurveda as an add-on to conventional management. This review reveals the beneficial role of Ayurveda in the management of migraines without many side effects. Yet several limitations exist, like small sample size, short follow up, and lack of better outcome measures for pre and post-assessments. Future research should overcome these limitations and follow a robust methodology so that definitive conclusions can be drawn.

Assessment of Information Literacy Competency of Management Science Students at the University of Ilorin, Kwara State, Nigeria

The study examined the information literacy (IL) competencies of management science students at the University of Ilorin, Nigeria. A survey research design was adopted. Data was collected through a questionnaire developed by the authors. A total of 337 randomly selected undergraduate students from six departments represent the sample for the study. Six research questions were developed and answered. The findings demonstrate that respondents generally perceived information literacy IL as an insight on how to effectively and efficiently access and select needed information and as a tool for long-life learning. Respondents have high IL skills in the use of the internet to access information needed in their field and can assess such information from various sources. Competence in the circulation of information, identifying and locating information, and accessing sources and evaluating information are the areas of strength revealed in the study; while the weaknesses identified are inability to determine when information is needed, none awareness of specific search engines. The results also reveal that respondents can use IL skills to retrieve information, search the library, and use specific search terms. Prominent information literacy courses offered are the use of libraries, introduction to computers, and IL training on the use of popular search engines such as Google and Ask Me. The common factors confronting the teaching of IL are power supply, high cost of computers, and limited time available for IL practical and hands-on.

CRISPER/Cas in Plant Natural Product Research: Therapeutics as Anticancer and other Drug Candidates and Recent Patents.

Clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR- associated9 (Cas9) endonuclease system is a facile, highly efficient and selective site-directed mutagenesis tool for RNA-guided genome-editing. CRISPR/Cas9 genome-editing strategy uses designed guide-RNAs that recognizes a 3 base-pair protospacer adjacent motif (PAM) sequence in the target-DNA. CRISPR/Cas-editing tools have mainly been employed in crop plants in relation to yield and stress tolerance. However, the immense potential of this technology has not yet been fully utilized in medicinal plants in deciphering or modulating secondary metabolic pathways producing therapeutically active phytochemicals against cancer and other diseases. The present review elucidates the use of CRISPR-Cas9 as a promising genome-editing tool in plants and plant-derived natural products with anticancer and other therapeutic applications. It also includes recent patents on the therapeutic applications of CRISPR-CAS systems implicated to cancer and other human medical conditions. Popular search engines, such as PubMed, Scopus, Google Scholar, Google Patents, Medline, ScienceDirect, SpringerLink, EMBASE, Mendeley, etc., were searched in order to retrieve literature using relevant keywords viz. CRISPER/Cas, plant natural product research, anticancer, therapeutics, etc., either singly or in various combinations. Retrieved citations and further cross-referencing among the literature have resulted in a total number of 71 publications and 3 patents are being cited in this work. Information presented in this review aims to support further biotechnological and clinical strategies to be carried using CRISPER/ Cas mediated optimization of plant natural products against cancer and an array of other human medical conditions. Off late, knock-in and knock-out, point mutation, controlled tuning of gene-expression and targeted mutagenesis have enabled the versatile CRISPR/Cas-editing device to engineer medicinal plants' genomes. In addition, by combining CRISPR/Cas-editing tool with next-generation sequencing (NGS) and various tools of system biology, many medicinal plants have been engineered genetically to optimize the production of valuable bioactive compounds of industrial significance.

How Search Engines Handle Suicide Queries


 
 
 The suicide contagion effect posits that exposure to suicide- related content increases the likelihood of an individual engaging in suicidal behavior. Internet suicide-related queries correlate with suicide prevalence. However, suicide-related searches also lead people to access help resources. This article systematically evaluates the results returned from both general suicide terms and terms related to specific suicide means across three popular search engines—Google, Bing, DuckDuckGo— in both English and Spanish. We find that Bing and DuckDuckGo surface harmful content more often than Google. We assess whether search engines show suicide prevention hotline information, and find that 53% of English queries have this information, compared to 13% of Spanish queries. Looking across platforms, 55% of Google queries include hotline information, compared to 35% for Bing and 10% for DuckDuckGo. Specific suicide means queries are 20% more likely to surface harmful results on Bing and DuckDuckGo compared to general suicide term queries, with no difference on Google.
 
 

The Content and Quality of Publicly Available Information About Congenital Diaphragmatic Hernia: Descriptive Study.

BackgroundCongenital diaphragmatic hernia (CDH) diagnosis in an infant is distressing for parents. Parents often feel unable to absorb the complexities of CDH during prenatal consultations and use the internet to supplement their knowledge and decision making.ObjectiveWe aimed to examine the content and quality of publicly available, internet-based CDH information.MethodsWe conducted internet searches across 2 popular search engines (Google and Bing). Websites were included if they contained CDH information and were publicly available. We developed a coding instrument to evaluate websites. Two coders (FS and KS) were trained, achieved interrater reliability, and rated remaining websites independently. Descriptive statistics were performed.ResultsSearches yielded 520 websites; 91 met inclusion criteria and were analyzed. Most websites provided basic CDH information including describing the defect (86/91, 95%), need for neonatal intensive care (77/91, 85%), and surgical correction (79/91, 87%). Few mentioned palliative care, decisions about pregnancy termination (13/91, 14%), or support resources (21/91, 23%).ConclusionsFindings highlight the variability of information about CDH on the internet. Clinicians should work to develop or identify reliable, comprehensive information about CDH to support parents.
