We describe the Mass Spectrometry Adduct Calculator (MSAC), an automated Python tool to calculate the adduct ion masses of a parent molecule. Here, adduct refers to a version of a parent molecule [M] that is charged due to addition or loss of atoms and electrons resulting in a charged ion, for example, [M + H]+. MSAC includes a database of 147 potential adducts and adduct/neutral loss combinations and their mass-to-charge ratios (m/z) as extracted from the NIST/EPA/NIH Mass Spectral Library (NIST17), Global Natural Products Social Molecular Networking Public Spectral Libraries (GNPS), and MassBank of North America (MoNA). The calculator relies on user-selected subsets of the combined database to calculate expected m/z for adducts of molecules supplied as formulas. This tool is intended to help researchers create identification libraries to collect evidence for the presence of molecules in mass spectrometry data. While the included adduct database focuses on adducts typically detected during liquid chromatography–mass spectrometry analyses, users may supply their own lists of adducts and charge states for calculating expected m/z. We also analyzed statistics on adducts from spectra contained in the three selected mass spectral libraries. MSAC is freely available at https://github.com/pnnl/MSAC.

IntroductionSeveral clinical prediction rules (CPRs) have been published, but few are easily accessible or convenient for clinicians to use in practice. We aimed to develop, implement, and describe the process of building a web-based CPR for predicting independent walking 1-year after a traumatic spinal cord injury (TSCI).MethodsUsing the published and validated CPR, a front-end web application called “Ambulation” was built using HyperText Markup Language (HTML), Cascading Style Sheets (CSS), and JavaScript. A survey was created using QualtricsXM Software to gather insights on the application's usability and user experience. Website activity was monitored using Google Analytics. Ambulation was developed with a core team of seven clinicians and researchers. To refine the app's content, website design, and utility, 20 professionals from different disciplines, including persons with lived experience, were consulted.ResultsAfter 11 revisions, Ambulation was uploaded onto a unique web domain and launched (www.ambulation.ca) as a pilot with 30 clinicians (surgeons, physiatrists, and physiotherapists). The website consists of five web pages: Home, Calculation, Team, Contact, and Privacy Policy. Responses from the user survey (n = 6) were positive and provided insight into the usability of the tool and its clinical utility (e.g., helpful in discharge planning and rehabilitation), and the overall face validity of the CPR. Since its public release on February 7, 2022, to February 28, 2023, Ambulation had 594 total users, 565 (95.1%) new users, 26 (4.4%) returning users, 363 (61.1%) engaged sessions (i.e., the number of sessions that lasted 10 seconds/longer, had one/more conversion events e.g., performing the calculation, or two/more page or screen views), and the majority of the users originating from the United States (39.9%) and Canada (38.2%).DiscussionAmbulation is a CPR for predicting independent walking 1-year after TSCI and it can assist frontline clinicians with clinical decision-making (e.g., time to surgery or rehabilitation plan), patient education and goal setting soon after injury. This tool is an example of adapting a validated CPR for independent walking into an easily accessible and usable web-based tool for use in clinical practice. This study may help inform how other CPRs can be adopted into clinical practice.

Abstract This work proposes an artifact oriented by Design Science (DS) methods for measuring the degree of boldness in business social actors, especially entrepreneurs and businesspeople. To construct the artifact, the work of Eysenck and Wilson (1975) was used. The methodological approach used was Design Science, as the present object of study is considered an information artifact and, as such, has functions of data processing, reducing entropy (vision of syntax), forming meaning (vision of representation), and achieving viability (vision of adaptation). To ensure the validity of the study, a sample of users made up of 30 organizational psychologists was used, selected by convenience. The results demonstrated that using the artifact allows to measure entrepreneurs’ degree of boldness, affording them greater assertiveness in choosing and structuring their business. The study has a number of implications for managerial practice since by using the artifact it is possible to measure an entrepreneur’s degree of boldness and allow more assertive choices and structuring of their business, all the while reducing the rate of micro and small businesses that die early. In the academic field, the artifact will enable research on the degree of boldness of businesspeople with diverse other organizational variables.

A dataset of vehicle MPG ratings and fuel cost calculations based on manufacturer, model, and fuel type.

PROJECT: Strategies to promote plug-in electric vehicle (PEV) adoption include consumer education about potential energy cost savings. However, the complexity of comparing gasoline and electricity prices makes it difficult to quantify. Vehicle energy cost calculators (VCCs) help consumers navigate this complexity, and research shows they can increase consumer knowledge and positive attitudes about PEVs. At least 12 of these calculators exist, but none appear to be based on behavioral research. They vary in terms of a number of features that are potentially important for user experience, education, and persuasion. This seed funding will support development of design specifications for vehicle energy cost calculators based on behavioral research. The researchers will draw implications for vehicle energy cost calculator design from literature on consumer perceptions of energy costs, fuel economy, and electric vehicle adoption as well as a systematic review of currently available VCCs. They will also conduct comparative usability testing with several existing vehicle energy cost calculators. The research team will disseminate findings to a range of stakeholders to encourage development and applications of vehicle energy cost calculators that facilitate PEV adoption.

DATA: This dataset is from a usability survey with VCC users who tested three VCCs and provide feedback on their usability.
