Assessment of the Fermentative Performance of Traditional Fresh Moroccan Sourdoughs and Their Freeze-Dried Forms Using Online Monitoring Device: Panigraph

The fermentative activity of sourdoughs and their stabilities are some of the main concerns of professionals in food science. The aim of this study was to evaluate the fermenting capacity of three traditional fresh sourdoughs and their freeze-dried forms with different compositions prepared by housewives in three different regions of Morocco. A device equipped with several sensors was developed to monitor several parameters simultaneously and in real time (the pH, dough rise, loss of mass, CO2 and ethanol release). The results showed that the duration of dough fermentation was long, ranging from 594 to 1210 min, with the specific volume ranging from 0.9 to 3.35 cm3/g−1. A strong and positive correlation between dough rise and CO2 release was observed, while ethanol release did not contribute directly to dough rise. The fresh sourdough FS1 showed better fermentative performance than the others, while the freeze-dried sourdough FDS3 was also of interest for bread making. The system used to generate the graphical fingerprints enabled us to read the main fermentation parameters directly in the same graph, as well as to compare several sourdoughs at once and choose the one best suited to our needs.

Popularizing precision: cultures of exactness at the Paris observatory, 1667–1742

ABSTRACT This article maps out the lexical landscape of precision from the late seventeenth to the early eighteenth century and investigate the various meanings of precision, both as a word and a concept, within the Paris Observatory and beyond. It argues that precision was first an attribute of instruments supposed to produce numerical measurements, like clocks and divided circles or sectors attached to optical devices. Less often, precision was applied to observers, the handling of instruments, and observational methods, including mathematical corrections applied to raw data. When all these aspects were combined the numerical result finally was also deemed to be precise. Moving to the debate about the shape of the Earth that shook the Academy of Sciences in the 1730s, it follows the way in which wider audiences were conveyed the various meanings of precision. Between the Cartesian resistance to the emergence of a professional science of precision and the pedagogical approach followed by the Newtonians such as Maupertuis, it argues that Cassini III embraced the professionalism of modern science, but did not feel that methodological precision was out of the reach of an educated public. While Maupertuis has seemed content with a discussion focusing on the precision of instruments and results, Cassini III set himself the hefty task of producing an accessible account of precision as a method of inquiry.

Heliophysics and amateur radio: citizen science collaborations for atmospheric, ionospheric, and space physics research and operations

The amateur radio community is a global, highly engaged, and technical community with an intense interest in space weather, its underlying physics, and how it impacts radio communications. The large-scale observational capabilities of distributed instrumentation fielded by amateur radio operators and radio science enthusiasts offers a tremendous opportunity to advance the fields of heliophysics, radio science, and space weather. Well-established amateur radio networks like the RBN, WSPRNet, and PSKReporter already provide rich, ever-growing, long-term data of bottomside ionospheric observations. Up-and-coming purpose-built citizen science networks, and their associated novel instruments, offer opportunities for citizen scientists, professional researchers, and industry to field networks for specific science questions and operational needs. Here, we discuss the scientific and technical capabilities of the global amateur radio community, review methods of collaboration between the amateur radio and professional scientific community, and review recent peer-reviewed studies that have made use of amateur radio data and methods. Finally, we present recommendations submitted to the U.S. National Academy of Science Decadal Survey for Solar and Space Physics (Heliophysics) 2024–2033 for using amateur radio to further advance heliophysics and for fostering deeper collaborations between the professional science and amateur radio communities. Technical recommendations include increasing support for distributed instrumentation fielded by amateur radio operators and citizen scientists, developing novel transmissions of RF signals that can be used in citizen science experiments, developing new amateur radio modes that simultaneously allow for communications and ionospheric sounding, and formally incorporating the amateur radio community and its observational assets into the Space Weather R2O2R framework. Collaborative recommendations include allocating resources for amateur radio citizen science research projects and activities, developing amateur radio research and educational activities in collaboration with leading organizations within the amateur radio community, facilitating communication and collegiality between professional researchers and amateurs, ensuring that proposed projects are of a mutual benefit to both the professional research and amateur radio communities, and working towards diverse, equitable, and inclusive communities.

Why is Citizen Science important for libraries?

Citizen science, as part of open science, holds significant importance for its participants, including citizen scientists and professional scientists who engage in collaborative scientific research (Booney et al., 2009). However, the benefits that organizers of citizen science gain are rarely emphasized. These organizers can include governmental organizations, non-governmental organizations, corporations, universities (Walker et al., 2016), as well as institutions such as libraries. Citizen science is important for libraries because it increases civic and research interests, scientific publishing, and scientific progress (Trouille, Lintott, and Fortson, 2019). Additionally, it helps libraries attract new users, enhance social cohesion, and improve the perception of library's social value (Cigarini et al., 2021). With the help of citizen science, libraries can enrich their collections and make them more accessible (Ignat et al., 2018), and librarians can develop new competencies.The presentation aims to provide a comprehensive understanding of the specific ways in which citizen science can benefit libraries and how libraries can effectively utilize citizen science to achieve their goals. Therefore, the benefits of citizen science for libraries will be discussed in detail, with examples and practical insights provided to illustrate their potential impact. The presentation will include an analysis and experience of the National and University Library in Zagreb with carrying out citizen science activities and the advantages this institution had for librarian education. It will highlight the essential role of libraries as implementers of citizen science activities and the impact of such activities on the positioning of libraries in local society and the scientific community.

Skill analysis of library and information science professionals

This paper investigated professional skills for library and information science (LIS) professionals based on the American Library Association (ALA) job website. The study identified job categories and library types, examined required soft skills and professional skills, and analyzed the relationships between professional skills and job categories, and the relationships between professional skills and library types as well. Data mining, subject analysis, and information visualization methods were used in the study. The findings of this study show that the LIS field demands a wide range of comprehensive professional skills. In total, over 160 distinct professional skill requirements and 24 skill themes were uncovered. Across various LIS job categories, an average of 8.84 professional skill themes per job category was found to be necessary for success. Among these skill themes, certain ones stood out as particularly in-demand, including: Productivity Software, MARC Standards and Guidance, Integrated Library Automation, Programming, and Data Analysis. Furthermore, it was observed that the specific professional skill requirements varied across different types of libraries. Notably, Academic/Research (College/University) libraries and Public Libraries stood out as two types that demanded a broader range of professional skill themes compared to other types of libraries. The findings of this research study can inform library and information science researchers, educators, and professionals to better understand the LIS professional skill requirements, improve existing curricular systems, and develop new courses to meet the job market needs.

Development, implementation, and testing of LGBTQIA+ care curriculum for health science professionals: Research protocol.

Lesbian, Gay, Bisexual, Transgender, Queer, Intersex and Asexual (LGBTQIA+) people struggle to identify a healthcare service that understands their problems and needs. Additionally, healthcare professionals also find it difficult to care for LGBTQIA+ as very little is studied or heard about management. The article presents a protocol for a pilot study aimed at the development of an LGBTQIA+ care curriculum for health science professionals. The study includes Phase I: The development of a curriculum based on a literature review and focus group discussion among LGBTQIA+ individuals, and Phase II: Pilot testing of LGBTQIA+ care curriculum. The study outcome will reflect the improvement in the knowledge of healthcare professionals on LGBTQIA+ care.

Equivalence of citizen science and scientific data for modelling species distribution of birds from a tropical savanna

AbstractThe Wallacean deficit continues to be a challenge to species distribution modelling. Although some authors have suggested that data collected by citizen scientists can be relevant for a better understanding of biodiversity, to our knowledge, no work has quantitatively tested the equivalence between scientific and citizen science data. Here, we investigate the hypothesis that data collected by citizen scientists can be equivalent to data collected by professional scientists when generating species spatial distribution models. For 42 bird species in the Cerrado region we generated and compared species distribution models based on three data sources: (1) scientific data, (2) citizen science data and (3) sample size corrected citizen science data. To test our hypothesis, we compared the equivalence of these datasets. We rejected the hypothesis of equivalence for about one‐third (38%) of the evaluated species, revealing that, for most of the species considered, the models generated were equivalent irrespective of the data set used. The distances between centroids of the models that were equivalent were on average smaller than the distances between non‐equivalent models. Also, the direction of change in the models showed no pattern, with no trend towards more populated regions. Our results show that the use of data collected by citizen scientists can be an ally in filling the Wallacean deficit gap. In fact, the lack of use of this wide range of data collected by citizen scientists seems to be an unjustified caution. We indicate the potential of using citizen science data for modelling the distribution of species, mainly due to the large set of data collected, which is impracticable for scientists alone to collect. Conservation measures will be favoured by the union of professional and amateur data, aiming for a better understanding of species distribution and, consequently, biodiversity conservation.

Evaluación de la simulación de alta fidelidad con actores en cuidados paliativos y estudiantes de Enfermería: un estudio de método mixto

ObjectiveThe most effective training methods are experiential, including those focused on experiences and emotions. Clinical simulation, especially high-fidelity simulation, is one of the most effective methodologies for the acquisition of competencies in care like palliative care. The simulation with actors can train future healthcare science professionals in technical, intellectual, or interpersonal skills. The objective is to evaluate high-fidelity simulation with actors as a tool in palliative care training for nursing students. MethodOver three years, the study was conducted in the Faculty of Nursing of Murcia with nursing students. A mixed methods study with sequential explanatory design in three moments was conducted: 1)Quasi-experimental study in a single group (n=12) before and after attending the palliative care course with clinical simulation with actors to assess the communication skills (CICAA scale). 2)Qualitative study with phenomenological perspective after clinical simulation (174 reflective students’ narratives). 3)Cross-sectional observational study, one year later, to assess the transfer of knowledge and skills to the clinical practice (71 students). ResultsStudents who interacted with actors in clinical simulation improved their communication skills and the ability to establish an effective helping relationship with both end-of-life patients and their families. The students perceived the clinical simulation as an innovative learning methodology that is useful to encourage reflection and transfer of learning during their clinical internship. ConclusionsStandardization of the use of active learning methodologies is recommended for a better acquisition of transversal skills such as communication skills in palliative care.

Catering to the experts: food marketing and health professionals in the early 20th century

PurposeThis paper aims to examine the marketing strategies designed by three innovative early 1900s food companies. It traces the coordination of these businesses’ research funding, advertising, direct mail and promotional tactics to show how they intersected and impacted consumers and health professionals in the period when scientists were first able to quantify the relationship between good health and food. The paper analyzes internal company documents, advertisements and marketing materials from Knox Gelatine, Borden and Sunkist.Design/methodology/approachResearch for this paper benefited from the author’s unlimited access to the private documents of the Knox Gelatine Company and its executives. These documents were analyzed chronologically and thematically. They chronicled the company’s attempts to influence the medical world and the ways it cultivated home economists. The paper also used publicly available digitized documents from Sunkist and Borden. The paper would benefit from further detailed analysis of these documents to parse Knox’s targeting by race and ethnicity.FindingsIn the 1920s, Knox, Borden and Sunkist developed a marketing strategy which leveraged a new class of experts – the hundreds of thousands of medical professionals, home economists, teachers and government agents who advised American women. By distributing specific laboratory research on the nutritional benefits of their products to this emerging class of health professionals and the consumers who trusted them, these companies developed relationships with opinion leaders designed specifically to influence product sales.Research limitations/implicationsThis research benefited from access to the private documents of Knox Gelatine Company which divulge the company’s attempts to influence the medical world and cultivate home economists. The paper would benefit from further analysis of these documents to parse the company’s targeting by race and ethnicity as well as a deeper comparison to companies that tried to work with health professionals unsuccessfully and companies that adopted this tactic in the household products or tobacco area. Opportunities also exist to do a fuller analysis of variations in food marketing by rural versus urban as well as race.Originality/valueBy reconstructing the sequencing and content of these three companies’ 1920s marketing strategies, this research uncovers a form of early 20th century food marketing directed at health and science professionals which has been neglected in advertising histories.

A scientometrics analysis of equity, diversity, inclusion, and accessibility (EDIA) literature in library and information science profession

Purpose Equity, diversity, inclusion and accessibility (EDIA) are the core values of librarianship. This study aims to examine the EDIA literature in the library and information science (LIS) profession, focusing on publishing trends, authorship patterns, thematic evolution, co-occurrence network, international collaboration network and three-factor analysis. Design/methodology/approach A scientometrics analysis was performed, and data were retrieved from the Web of Science database following a four-phase data extraction and filtration process. Data analysis was performed using specialized scientometrics tools. Findings Most of the published work comes from the developed world. The thematic evolution identified that the initial period (1971–2010) was dedicated to the diversity of library resources, services and users. The second phase (2011–2015) concentrated on accessibility and information literacy. The recent period (2016–2021) is linked with social inclusion, diversity and accessibility. Furthermore, the co-cluster citation and content analysis identified five major interconnected streams in the EDIA literature in LIS: disability and accessibility; diversity, inclusion and recruitment; social justice and libraries; libraries and immigrants; and libraries and the lesbian, gay, bisexual, transgendered, queer community. Research limitations/implications Theoretical, practical and implications for policy makers and curriculum developers were added to create awareness and better observe EDIA in LIS field. Originality/value The identification of research streams is one of the most important findings of this study, which shows that some areas of EDIA are maturing and others are emerging in the profession.

Force plate methodologies applied to injury profiling and rehabilitation in sport: A scoping review protocol.

Musculoskeletal injuries are a common health problem among sporting populations. Such injuries come with a high financial burden to the involved organisations and can have a detrimental impact on the career attainment of injured individuals. Force plates are now a common tool available to sport and exercise science and medicine professionals to enable them to profile injury risk predisposition and modulate the rehabilitation process within sporting environments. This is because contemporary force plate technology is portable and affordable and often comes with software that enables the automatic and immediate feedback of test variables to key stakeholders. However, to our knowledge, to date, there has been no comprehensive review of the scientific literature pertaining to clinical applications of force plate technology. Therefore, this article presents a protocol and a methodological framework to perform a scoping review to identify and map the available scientific literature in which force plates have been applied to the injury profiling and rehabilitation of athletes. The specific aims of the scoping review are 1) to identify and describe the force plate tests, methodologies, and metrics used to screen for injury risk and guide the return of injured athletes to full-time training and competition, 2) to identify potential trends and/or differences by participants' age, sex, and/or level of performance in tests, methodologies, and metrics selected, and 3) to identify key gaps in the existing evidence base and new questions that should be addressed in future research. The global aim of the scoping review is to improve practitioner decision-making around force plate test and variable selection when applied to the injury prevention and rehabilitation of sporting populations.
