Data from: Aragonite bias exhibits systematic spatial variation in the late Cretaceous Western Interior Seaway, North America
Preferential dissolution of the biogenic carbonate polymorph aragonite promotes preservational bias in shelly marine faunas. Whilst field studies have documented the impact of preferential aragonite dissolution on fossil molluscan diversity, its impact on regional and global biodiversity metrics is debated. Epicontinental seas are especially prone to conditions which both promote and inhibit preferential dissolution, which may result in spatially extensive zones with variable preservation. Here we present a multi-faceted evaluation of aragonite dissolution within the late Cretaceous Western Interior Seaway of North America. Occurrence data of molluscs from two time intervals (Cenomanian-Turonian boundary, early Campanian) are plotted on new high-resolution paleogeographies to assess aragonite preservation within the seaway. Fossil occurrences, diversity estimates and sampling probabilities for calcitic and aragonitic fauna were compared in zones defined by depth and distance from the seaway margins. Apparent range sizes, which could be influenced by differential preservation potential of aragonite between separate localities, were also compared. Our results are consistent with exacerbated aragonite dissolution within specific depth zones for both time slices, with aragonitic bivalves additionally showing a statistically significant decrease in range size compared to calcitic fauna within carbonate-dominated Cenomanian-Turonian strata. However, we are unable to conclusively show that aragonite dissolution impacted diversity estimates. Therefore, whilst aragonite dissolution is likely to have affected the preservation of fauna in specific localities, time averaging and instantaneous preservation events preserve regional biodiversity. Our results suggest that the spatial expression of taphonomic biases should be an important consideration for paleontologists working on paleobiogeographic problems.

Systematic Literature Review on Web Performance Testing
<p>Performance Testing is essential to ensure the quality and scalability of Web applications. A well-defined process may guide Performance Testing Engineer in conducting this task. We intended to enlighten some major inputs related to web performance testing. For this, we have formulated and executed a given protocol, according to the Systematic Literature Review (SLR) protocol in Software Engineering. So, 37 papers were selected/analyzed and we have extracted their most relevant contribution in order to answer our research questions. This analysis enabled us discovering preeminent performance testing profiles/roles, approaches, artifacts, methods, stages or phases and activity flows that have been reported in the literature. We believe that, despite those several studies that mapping performance test context, there are a few remarks in which a clarification might be needed, once there is no well-established process that comprises the whole activities mapped as well as established a relation with other studies. Therefore, this study intends to provide relevant input that one may establish a novel web performance testing process.</p>
Data from: Reporting guidelines for community-based participatory research (CBPR) did not improve the reporting quality of published studies: a systematic review of studies on smoking cessation
<p>Although a guideline for reporting the results of community-based participatory research (CBPR) was published in 2010, the impact on the quality of reporting a CBPR on smoking cessation is unknown. Here we provide the raw data of a systematic review that assessed the impact of a 2010 community-based participatory research reporting guideline. on the quality of reporting a CBPR on smoking cessation. Specifically, we searched the MEDLINE, Embase, the Cochrane Central Register for Controlled Trials (CENTRAL), PsycINFO, and CINAHL databases and included articles published up to October 2018 (PROSPERO: CRD42019111668). We assessed reporting quality using a 13-item checklist.</p>
Superb microvascular imaging (SMI) in the evaluation of musculoskeletal disorders: a systematic review
<p><strong>Objectives: </strong>To systematically review the current literature concerning the role of superb microvascular imaging (SMI), a novel Doppler technique that enables detection of fine vessels and slow blood flow, in the evaluation of musculoskeletal disorders.</p> <p><strong>Methods: </strong>An online search of the literature was conducted for the period 2013 to April 2019 and included original articles written in English language. A data analysis was performed at the end of the literature search.</p> <p><strong>Results: </strong>Eight original articles with prospective design and one with retrospective design were included in this review: 4 studies focused on rheumatoid arthritis, 2 on rheumatoid and other arthritides, 1 on lateral epicondylosis and 2 on carpal tunnel syndrome. Sample size ranged from 26 to 83 patients. Despite some methodological differences, all studies compared the performance of SMI with that of a conventional Doppler technique such as power and color Doppler and found an improvement in vascularity detection with SMI. The main variations were in sample size, evaluated parameters and vascularity interpretation methods. Inter-observer agreement for SMI ranged from moderate to excellent.</p> <p><strong>Conclusions: </strong>SMI is a promising tool for the diagnosis and treatment planning of different musculoskeletal disorders. Future investigations should include larger samples of patients with long-term follow-up.</p>
