“…Primo was not included in Lowe et al's 2018 study but assuming their results hold for Primo, this further supports the simplification of an initial encounter with a search interface. In a study comparing relevance and overlap of simple Boolean and advanced Boolean Lowe et al (Lowe et al, 2020) found that simple Boolean actually outperformed advanced Boolean overall. When one considers the fact that the Basic Search mode in Primo returns the exact same results for explicitly typed Boolean queries using nested parentheses as it does when those same queries are executed using the Advanced Search mode, the case against having a complex search interface on a homepage is closed.…”

“…These researchers discovered that Boolean is not "better" than natural language/phrase searching (p. 529). Subsequent work by Lowe et al (Lowe et al, 2020) continued to explore researchers' habits and behaviors related to searching, finding that "based on relevance, there is no compelling evidence that either search is superior" and that "simple search is likely to be much more realistic in anticipating a student approach" (p. 5). Those researchers supported their findings noting the congruity with other recent studies, citing students' difficulty in finding information such as defining search terms and using discipline-specific databases.…”

Library discovery platforms, which provide searchable user interfaces as their front-facing layer, aggregate tremendous amounts of metadata from multiple data streams describing a wide variety of print and electronic resources. Complicating the matter further, resources may differ in availability or delivery time depending not only on their media but also upon the source of the data stream describing them. How should libraries structure end users’ options for searching discovery platforms in light of the many options available? This study used a nonexperimental design and quantitative methods to analyze users’ revealed preferences for query type in twenty-four academic libraries in a data set containing metadata, sans queries, for over 64 million searches. Libraries studied were all located in California, used the same discovery layer software, and served similar user and faculty constituencies; however, the number of query types and pre-filtering options available differed between institutions. Results show that, when users were presented with the choice between search options, most conducted simple, more broad searches rather than complex and specific searches. When search options were highly constrained by the default choice architecture, but complex searches were possible, few users opted out of the default simple search. Implications for usability of discovery layers and the motivations of librarians in choice architecture are nontrivial and are discussed. The desires of librarians and “power user” faculty must be balanced with the fact that most users are novices and users of all abilities are largely habituated to commercial search products which emphasize post-search results filtering.

“…The Scopus database was searched using simple and advanced Boolean logic concepts. It was then filtered to obtain as many articles as possible relevant to the research objectives [72]. The search result was filtered according to publication year, subject area, document type, and source type and restricted to English language peerreviewed journals and articles.…”

The energy sector accounts for about two-thirds of all human-related greenhouse gas (GHG) emissions due to the reliance on fossil-based fuels. This is a significant concern as it can have dire consequences on the survival of humankind and disrupt other natural processes. The research indicated that some mitigation measures to curb GHG emissions are to increase energy from low-carbon sources such as nuclear. However, due to the continuous adverse climate change impact, a comprehensive systematic review of research in this area must be conducted to inform policy practice and future studies. This study attempts to address this gap by mapping the global reflections on the potential of nuclear technology to mitigate GHG through a bibliometric review process. A total of 741 studies were retrieved from the Scopus database and a few from Google Scholar, spanning from 1962 to 2022, and analyzed using a science mapping tool—VOSviewer. The study confirmed that fossil fuels are a significant source of greenhouse gas emissions and contributor to greenhouse emissions. Those authors concluded that promoting clean and alternative energy sources to fossil fuels would help reduce carbon emissions. Although renewable energy has proven to be very efficient among pollution and climate change mitigation sources, nuclear energy is the most dependable option for meeting national and regional CO2 emission targets while meeting energy supply needs. The bibliometric analysis with VOSviewer suggested that only five African countries, including Ghana, have contributed to the research area with limited collaboration. As a result, it calls for stakeholders to make informed decisions to invest resources in research to address the challenge on the continent. The MESSAGE planning model is recommended for the study.

“…Search keywords included 'pre-service teacher', 'identity', 'personal identity' and 'professional identity'. Using the Boolean search strategy (Lowe et al, 2020), Te Waharoa and Google Scholar databases were searched for empirical, peer-reviewed journal articles, published in English between 2012-2022. Search strings and joining keywords using "AND" increased relevant search results.…”

What Makes Me, Me? Factors influencing pre-service teacher personal identity development during professional practice

<p>The concept of identity can be broken up into two constructs: personal and professional. Developing teacher professional identity is an important part of becoming a teacher. Research suggests pre-service teachers primarily develop their professional identity during professional practice. Personal and professional identities are interlinked, and conflict can arise when pre-service teachers take their personal identity on professional practice. In the past ten years, much research about pre-service teacher professional identity development had been completed, while personal identity was largely overlooked. This phenomenological study uses qualitative methods including ecomaps, semi-structured interviews, and field notes to investigate factors influencing primary school pre-service teacher personal identity development during professional practice. Reflexive thematic analysis revealed themes situated within Bronfenbrenner’s ecological systems, including factors that enable, challenge, or enable and challenge identity development. Findings suggest pre-service teachers’ individual aspects and contextual factors, primarily whānau, can influence identity development, and imply the role of resilience. This study poses implications for pre-service teachers, initial teacher education providers, educators, professional practice schools, and researchers.</p>
