Are Reemployment Services Effective? Experimental Evidence from the Great Recession
We examine an experimental-design reemployment program implemented in Nevada during the Great Recession that required Unemployment Insurance (UI) recipients to: (1) undergo an eligibility review to confirm they were qualified for benefits and actively searching for work and, if deemed eligible, (2) receive job-counseling services. Our results show that the program expedited participant exit from UI, produced UI savings that exceeded program costs, and improved participant employment outcomes. Analyses of program effects on the UI exit likelihood show that the program's effects are partly associated with increased participant exit up through the time when program activities were scheduled, reflecting voluntary exit of participants from UI to avoid program activities and disqualifications of participants who failed to meet eligibility requirements. In addition, the program induced substantial participant exit from UI in the period after participants fulfilled requirements and their interactions with the program had ended, suggesting that the job-counseling services offered by the program may have helped participants to conduct more effective job searches. Our findings provide evidence that reemployment programs that combine an eligibility review with mandatory participation in job-search services can be effective during recessions.
Visual Topic Semantic Enhanced Machine Translation for Multi-Modal Data Efficiency
The scarcity of bilingual parallel corpus imposes limitations on exploiting the state-of-the-art supervised translation technology. One of the research directions is employing relations among multi-modal data to enhance performance. However, the reliance on manually annotated multi-modal datasets results in a high cost of data labeling. In this paper, the topic semantics of images is proposed to alleviate the above problem. First, topic-related images can be automatically collected from the Internet by search engines. Second, topic semantics is sufficient to encode the relations between multi-modal data such as texts and images. Specifically, we propose a visual topic semantic enhanced translation (VTSE) model that utilizes topic-related images to construct a cross-lingual and cross-modal semantic space, allowing the VTSE model to simultaneously integrate the syntactic structure and semantic features. In the above process, topic similar texts and images are wrapped into groups so that the model can extract more robust topic semantics from a set of similar images and then further optimize the feature integration. The results show that our model outperforms competitive baselines by a large margin on the Multi30k and the Ambiguous COCO datasets. Our model can use external images to bring gains to translation, improving data efficiency. Keywords multi-modal machine translation, visual topic semantics, data efficiency
Voice-Related Quality of Life Questionnaire
Background The Voice-Related Quality of Life (V-RQOL) questionnaire is one of the widely used patient-reported outcome measures for evaluating the impact of voice disorders. Numerous translated versions exist; however, no comprehensive review has synthesized their cross-cultural adaptation procedures and psychometric properties. The purpose of this systematic review was to evaluate the methodological rigor and psychometric quality of translated V-RQOL versions across languages, using the Critical Appraisal Skills Programme (CASP) checklist. Method Articles were systematically extracted from the literature review using search engines, including EMBASE, Scopus, Google Scholar, Web of Science, and PubMed. The authors extracted the articles to find English studies published between 1999 and 2025. After conducting the screening, we included the paper that met the eligibility criteria for the study. The researchers of the current study employed the CASP to assess the methodology of the papers. The review included versions of V-RQOL that were translated, adapted, and validated for linguistic or cultural variations. Results A total of 2346 records were found; after removing duplicates, 1408 remained. Fifteen full texts were reviewed, and 14 met the inclusion criteria. All used systematic translation, cultural adaptation, pilot testing, and psychometric evaluation. The CASP appraisal showed clear aims and suitable methods, but insufficient details on translation panels and sampling. Reliability was strong, though construct validity approaches differed. Some versions lacked methodological rigor. The Azerbaijani-Turkish version showed excellent reliability and consistency, matching other validated forms. Conclusions This systematic review highlights that cross-cultural adaptations of the V-RQOL consistently demonstrate strong reliability and validity across diverse languages. CASP appraisal confirmed methodological rigor in most studies, though variability in pilot testing and reporting remains. The V-RQOL is a robust tool for assessing voice-related quality of life globally. Future adaptations should follow standardized guidelines and incorporate CASP-based evaluations to ensure cultural relevance and methodological transparency.
Fast and comprehensive N- and O-glycoproteomics analysis with MSFragger-Glyco
Recent advances in methods for enrichment and mass spectrometric analysis of intact glycopeptides have produced large-scale glycoproteomics datasets, but interpreting these data remains challenging. We present MSFragger-Glyco, a glycoproteomics mode of the MSFragger search engine, for fast and sensitive identification of N - and O -linked glycopeptides and open glycan searches. Reanalysis of recent N -glycoproteomics data resulted in annotation of 80% more glycopeptide spectrum matches (glycoPSMs) than previously reported. In published O -glycoproteomics data, our method more than doubled the number of glycoPSMs annotated when searching the same glycans as the original search, and yielded 4- to 6-fold increases when expanding searches to include additional glycan compositions and other modifications. Expanded searches also revealed many sulfated and complex glycans that remained hidden to the original search. With greatly improved spectral annotation, coupled with the speed of index-based scoring, MSFragger-Glyco makes it possible to comprehensively interrogate glycoproteomics data and illuminate the many roles of glycosylation. MSFragger-Glyco allows identification of N - and O -linked glycopeptides using the localization-aware open search strategy of the MSFragger search engine.
Online Health Information Seeking Behaviors Among Older Adults: Systematic Scoping Review
With the world's population aging, more health-conscious older adults are seeking health information to make better-informed health decisions. The rapid growth of the internet has empowered older adults to access web-based health information sources. However, research explicitly exploring older adults' online health information seeking (OHIS) behavior is still underway. This systematic scoping review aims to understand older adults' OHIS and answer four research questions: (1) What types of health information do older adults seek and where do they seek health information on the internet? (2) What are the factors that influence older adults' OHIS? (3) What are the barriers to older adults' OHIS? (4) How can we intervene and support older adults' OHIS? A comprehensive literature search was performed in November 2020, involving the following academic databases: Web of Science; Cochrane Library database; PubMed; MEDLINE; CINAHL Plus; APA PsycINFO; Library and Information Science Source; Library, Information Science and Technology Abstracts; Psychology and Behavioral Sciences Collection; Communication & Mass Media Complete; ABI/INFORM; and ACM Digital Library. The initial search identified 8047 publications through database search strategies. After the removal of duplicates, a data set consisting of 5949 publications was obtained for screening. Among these, 75 articles met the inclusion criteria. Qualitative content analysis was performed to identify themes related to the research questions. The results suggest that older adults seek 10 types of health information from 6 types of internet-based information sources and that 2 main categories of influencing factors, individual-related and source-related, impact older adults' OHIS. Moreover, the results reveal that in their OHIS, older adults confront 3 types of barriers, namely individual, social, and those related to information and communication technologies. Some intervention programs based on educational training workshops have been created to intervene and support older adults' OHIS. Although OHIS has become increasingly common among older adults, the review reveals that older adults' OHIS behavior is not adequately investigated. The findings suggest that more studies are needed to understand older adults' OHIS behaviors and better support their medical and health decisions in OHIS. Based on the results, the review proposes multiple objectives for future studies, including (1) more investigations on the OHIS behavior of older adults above 85 years; (2) conducting more longitudinal, action research, and mixed methods studies; (3) elaboration of the mobile context and cross-platform scenario of older adults' OHIS; (4) facilitating older adults' OHIS by explicating technology affordance; and (5) promoting and measuring the performance of OHIS interventions for older adults.
Search Personalization Using Machine Learning
Firms typically use query-based search to help consumers find information/products on their websites. We consider the problem of optimally ranking a set of results shown in response to a query. We propose a personalized ranking mechanism based on a user’s search and click history. Our machine-learning framework consists of three modules: (a) feature generation, (b) normalized discounted cumulative gain–based LambdaMART algorithm, and (c) feature selection wrapper. We deploy our framework on large-scale data from a leading search engine using Amazon EC2 servers and present results from a series of counterfactual analyses. We find that personalization improves clicks to the top position by 3.5% and reduces the average error in rank of a click by 9.43% over the baseline. Personalization based on short-term history or within-session behavior is shown to be less valuable than long-term or across-session personalization. We find that there is significant heterogeneity in returns to personalization as a function of user history and query type. The quality of personalized results increases monotonically with the length of a user’s history. Queries can be classified based on user intent as transactional, informational, or navigational, and the former two benefit more from personalization. We also find that returns to personalization are negatively correlated with a query’s past average performance. Finally, we demonstrate the scalability of our framework and derive the set of optimal features that maximizes accuracy while minimizing computing time.

Television Advertising and Online Search
Despite a 20-year trend toward integrated marketing communications, advertisers seldom coordinate television and search advertising campaigns. We find that television advertising for financial services brands increases both the number of related Google searches and searchers' tendency to use branded keywords in place of generic keywords. The elasticity of a brand's total searches with respect to its TV advertising is 0.17, an effect that peaks in the morning. These results suggest that practitioners should account for cross-media effects when planning, executing, and evaluating both television and search advertising campaigns.

Recent Advancements and Challenges of AIoT Application in Smart Agriculture: A Review
As the most popular technologies of the 21st century, artificial intelligence (AI) and the internet of things (IoT) are the most effective paradigms that have played a vital role in transforming the agricultural industry during the pandemic. The convergence of AI and IoT has sparked a recent wave of interest in artificial intelligence of things (AIoT). An IoT system provides data flow to AI techniques for data integration and interpretation as well as for the performance of automatic image analysis and data prediction. The adoption of AIoT technology significantly transforms the traditional agriculture scenario by addressing numerous challenges, including pest management and post-harvest management issues. Although AIoT is an essential driving force for smart agriculture, there are still some barriers that must be overcome. In this paper, a systematic literature review of AIoT is presented to highlight the current progress, its applications, and its advantages. The AIoT concept, from smart devices in IoT systems to the adoption of AI techniques, is discussed. The increasing trend in article publication regarding to AIoT topics is presented based on a database search process. Lastly, the challenges to the adoption of AIoT technology in modern agriculture are also discussed.
