Performance Assessment of Communicable Disease Surveillance in Disasters: A Systematic Review
Conclusion Performance assessment is an integral component of the management of all organizations and the lack of performance assessment is considered a significant sign of weakness in an organization. Therefore, the lack of accepted mechanisms for the assessment of the performance of CDS systems in response to disasters is an important weakness. Although some studies attempted to assess surveillance systems, the results of this systematic literature review suggest that there is no clear and comprehensive assessment framework in place. While the CDC framework has been used in some studies, it is not specific for SS in resp...

Differences of Search Engine Digital Footprints Between Podiatrists and Foot and Ankle Orthopaedic Surgeons: A Need to Join the Digital Era
DISCUSSION: Foot and ankle-related Internet search terms results are overwhelmingly composed of podiatry-oriented sites. Per provider, regional differences are demonstrated, with FAOS having more sites in urban areas only. FAOS scope-of-practice terms such as "ankle replacement" still retain greater engagement by FAOSs. Search engine optimization and saturation strategies should be considered.LEVEL OF EVIDENCE: Level 3 (observational study).PMID:36067461 | DOI:10.5435/JAAOS-D-22-00189

Acupuncture for Post-stroke Shoulder-Hand Syndrome: A Systematic Review and Meta-Analysis
Conclusions: Acupuncture therapy seems effective for motor function, pain relief and activities of daily living in stroke patients with mild SHS, when it is used in combination with rehabilitation. The low certainty of evidence downgrades our confidence in making recommendations to clinical practice. Introduction Shoulder-hand syndrome (SHS) is a common condition among people who have had a stroke, with its reported prevalence ranging from 12% to 49% (1, 2). The main symptoms of SHS include pain, hyperalgesia, joint swelling and limitations in range of motion (ROM) (3). Post-stroke SHS is also named type I complex ...

Levy flights do not always optimize random search Biophysics and Computational Biology
It is generally believed that random search processes based on scale-free, Lévy stable jump length distributions (Lévy flights) optimize the search for sparse targets. Here we show that this popular search advantage is less universal than commonly assumed. We study the efficiency of a minimalist search model based on Lévy...

The role of memory for visual search in scenes
Many daily activities involve looking for something. The ease with which these searches are performed often allows one to forget that searching represents complex interactions between visual attention and memory. Although a clear understanding exists of how search efficiency will be influenced by visual features of targets and their surrounding distractors or by the number of items in the display, the role of memory in search is less well understood. Contextual cueing studies have shown that implicit memory for repeated item configurations can facilitate search in artificial displays. When searching more naturalistic envir...

43.5 depression-related internet search volume as a correlate of future child and adolescent suicides: a cross-correlational study of monthly google search volume and suicide rate of young individuals in the united states
This study examined whether the trends in MGSVs of any suicide-related search term preceded the variations in MSRs of young people in the United States.

Battling the Matthew Effect: Can Search Results be Fair?
Search engines are mediators between producers and consumers of information, and the order in which an engine presents its results affects both stakeholder groups in significant ways (e.g., economic livelihood). Top-ranked items provide their producers with much more exposure to the consumer than do lower-ranked items. If a search engine repeatedly returns comparably relevant items in the same order, the rich (more exposed) items will keep getting richer while lower-ranked items will get less and less relative exposure. The Text REtrieval Conference (TREC, trec.nist.gov) project at NIST contained a Fair Ranking track from...

Attention does not search uniformly Neuroscience
Difficult search tasks are known to involve attentional resources, but the spatiotemporal behavior of attention remains unknown. Are multiple search targets processed in sequence or in parallel? We developed an innovative methodology to solve this notoriously difficult problem. Observers performed a difficult search task during which two probes were flashed...

Data Flash: RIP PubMed Health
This is not exactly a data post, but, the loss of a trusted source for clinical effectiveness research will have its effects on the dataverse.  PubMed Health is being discontinued as of this coming Wednesday.  As any of my colleagues can tell you, I’m taking the loss of PubMed Health hard– I loved showing it to people at various conferences, and using it myself– I found it a wonderful mid-point between MedlinePlus.gov and PubMed.gov, and it also had some great methodology resources and a glossary.  All of its content will be findable in other ways though! In thinking about how to proceed in future with...

Intrinsic motivation and attentional capture from gamelike features in a visual search task.
Abstract In psychology research studies, the goals of the experimenter and the goals of the participants often do not align. Researchers are interested in having participants who take the experimental task seriously, whereas participants are interested in earning their incentive (e.g., money or course credit) as quickly as possible. Creating experimental methods that are pleasant for participants and that reward them for effortful and accurate data generation, while not compromising the scientific integrity of the experiment, would benefit both experimenters and participants alike. Here, we explored a gamelike sys...

Multimodal neuroimaging evidence linking memory and attention systems during visual search cued by context
Visual search can be facilitated by the learning of spatial configurations that predict the location of a target among distractors. Neuropsychological and functional magnetic resonance imaging (fMRI) evidence implicates the medial temporal lobe (MTL) memory system in this contextual cueing effect, and electroencephalography (EEG) studies have identified the involvement of visual cortical regions related to attention. This work investigated two questions: (1) how memory and attention systems are related in contextual cueing; and (2) how these systems are involved in both short‐ and long‐term contextual learning. In one ...

Expectation violations in sensorimotor sequences: shifting from LTM‐based attentional selection to visual search
Long‐term memory (LTM) delivers important control signals for attentional selection. LTM expectations have an important role in guiding the task‐driven sequence of covert attention and gaze shifts, especially in well‐practiced multistep sensorimotor actions. What happens when LTM expectations are disconfirmed? Does a sensory‐based visual‐search mode of attentional selection replace the LTM‐based mode? What happens when prior LTM expectations become valid again? We investigated these questions in a computerized version of the number‐connection test. Participants clicked on spatially distributed numbered shapes...
