Collection Development Policies for Special Collections at Selected Academic Libraries
Authors: Faulkner James , Kim Jeonghyun 
Published: October 2022

ABSTRACTCollection development policies for university special collections and archives guide archival appraisal, which is the process by which archivists determine the value of an item. Much has been written about appraisal theory, but little is known about archivists' actual appraisal practice and how collection policy guides such practice. The object of this paper is to explore the appraisal practices of archivists by examining collection development policies. As a preliminary examination, this study analyzed the collection development policies of seven Texas tier‐one institutions. The most common component of the policies was a statement on the types of items collected or excluded. The study also found that the language used for these formats varied considerably with no standardization. The policies themselves also varied widely in detail.

Authors: Goh Dion Hoe‐Lian , Lee Chei Sian , Zheng Han , Theng Yin Leng 
Published: October 2022

ABSTRACTWe conducted an exploratory study of the links found in Twitter tweets. Our results showed that the largest category of tweet links was social media platforms followed by alternative news sites. Government agencies and educational institutions were under‐represented. In terms of relevance, about 75% of the links were related to COVID‐19 but disappointingly, only 40% of the links were directly related to their respective tweets' topics.

Authors: Islam Md. Anwarul , Howlader Ahmadul Islam , Roy Prodip 
Published: October 2022

ABSTRACTThe objective of this study is to examine and analyze the use of Google Scholar metrics by a cohort of Bangladeshi library and information science (LIS) researchers. This study is a follow‐up to Islam and Roy (2021)’s study, which identified publications published by Bangladeshi LIS researchers in the Scopus and Web of Science (WoS) databases. We collected data purposively from the GS Profiles of LIS researchers working in different public and private universities. Only 32 LIS researchers in Bangladesh have a GS profile, with a total of 646 publications and 5,752 citations listed in their GS profiles. All LIS researchers have an h‐index, and our study identified strong correlations between the GS Citation metrics (publications, citations, h‐index). However, the overall scholarship visibility is low. This is the first time an attempt has been made to examine publication metrics of GS in the context of Bangladeshi LIS researchers. These findings would help policymakers and researchers integrate GS Profile into the university website to display their scholarship activities.

Published: October 2022

ABSTRACTWeibo is a widely used social media platform showing all kinds of information related to the COVID‐19 pandemic promptly in China. Official media and private media are two typical types of media on Weibo. Due to the different characteristics of these two media types, in the context of public health emergencies, it is worth exploring whether there are differences in the users' interactive behavior with information from these two types of media. This is of great significance to the integration and development of these two types of media.This study obtained data on the interaction behaviors of Weibo users with posts published by the two media types at various stages of the pandemic. Statistical analyses have confirmed significant differences in interaction behavior data between users and these two media types. In future research, based on the findings of this study, we will investigate the reasons behind these differences to provide relevant guidelines and suggestions for the release of different media in public health emergencies by conducting a deep dive analysis of user reviews.

Quantifying Individual Research's Distance from the Trends based on Dynamic Topic Modeling
Authors: Meng Jie , Lou Wen , He Jiangen 
Published: October 2022

ABSTRACTResearch trends are the keys for researchers to decide their research agenda. However, only few works have tried to quantify how scholars follow the trends. This paper addresses this problem by proposing a novel measurement for quantifying how a scientific entity (paper or researcher) follows the hot topics in a research field. Specifically, the topic evolution and papers are vectorizing by dynamic topic modeling. Then the degree of hotness tracing is explored from three different perspectives: mainstream, short‐term direction, long‐term direction. Papers and researchers in the field of Computer Vision from 2006 to 2017 were selected to evaluate our method. Further study will show the results of topic evolution patterns and researchers' clusters.
Professional Development: Perception among School Librarians
Authors: Munyao Moses M. 
Published: October 2022

ABSTRACTThe roles of school librarians as well as the needs of library users have been changing. To keep up with the changes, school librarians have been required to engage in professional development which enables them to acquire the necessary knowledge and skills for the effective provision of services and programs to their clients. School districts formulate policies that provide guidelines on the professional development requirements and activities for school librarians but there have been concerns on the effectiveness and approach of professional development as outlined in the policies. Using Ball's policy cycle theoretical framework, the study analyzed professional development policies within schools and interviewed school librarians to understand their perception of professional development. Findings from the study will enable librarians and administrators within the school and districts to understand the current state of professional development and may also suggest effective and innovative strategies in professional development for school librarians.
Factors Influencing Criminologists' Open Research Data Practices: Trust, Contract, and Value
Authors: Shih Yi‐Ru , Yang Yu‐Ju , Jeng Wei 
Published: October 2022

ABSTRACTThis study investigated how researchers in criminology dealt with their research data and explored the potential factors that would influence their willingness to share and reuse others' research data. Our findings unveiled three factors, trust, contract, and value, deeply rooted in researchers' attitudes and their data sharing and reuse patterns and behaviors. Through comprehending their concern behind sharing and reusing research data, we seek crucial insights that could be beneficial in developing a criminological research data repository, further consolidating the research data infrastructure in social science. Sharing and reusing data can advance scientific research and provide innovative possibilities for practice in criminology (e.g., new correctional methods, new crime prevention policies), providing sustained and thriving energy for the field.

Authors: Song Yijia , Fang Zhichao , Fu Hui‐Zhen 
Published: October 2022

ABSTRACTAs interdisciplinary research attracts more attention, interdisciplinarity has become a significant factor to be explored for scientific impact. This study explored the influence of interdisciplinarity on scientific impact in the field of climate change, based on Web of Science data. Taking newly‐developed indicator DIV* and its components as interdisciplinarity measures, we used OLS regression and topic analysis to analyze their relationships with short‐term and long‐term scientific impact, respectively. We found that DIV* had an inverted U‐shaped relationship with scientific impact in overall positive correlation, and both long‐ and short‐term scientific impact increased with the growth of interdisciplinarity with a declining growth rate in most cases. For the three components of DIV*, balance and disparity are negatively and positively correlated with scientific impact, respectively, while variety has an inverted U‐shaped relationship. These findings provided theoretical and decision‐making support for evaluating the impact of interdisciplinary research in the field of climate change.
Towards a Diversity, Equity, and Inclusion (DEI) Competency Framework: A Content Analysis of Visible DEI Efforts on LIS Associations' Websites
Authors: Tang Rong , Hu Zhan , Pallo Bianca 
Published: October 2022

ABSTRACTIn this poster, we report the findings of an investigation of 28 LIS associations' DEI efforts as evidenced through their websites. The DEI efforts were documented in terms of whether DEI was mentioned in associations' missions and goals, their code of conducts, and their competency frameworks, whether the associations provided DEI definitions, whether there were position statements, whether there were dedicated units leading the DEI efforts, whether there were specific DEI resources, and whether there were relevant contents on the homepage or as menu items. While we discovered the common patterns of DEI practice, we also uncovered notable gaps. Our findings contribute to a better understanding of the role of associations in promoting and fostering DEI, it also shows the need for a consistent and visible effort for LIS associations to lead their professional community toward a robust work in DEI and developing a DEI competency framework for LIS professionals.
Persuasion in Audio‐based Social Media: A Clubhouse Interview Study
Authors: Xiao Lu , Wang Yueyue , Wei Xinyi 
Published: October 2022

ABSTRACTClubhouse is an audio‐based social media platform launched in March 2020. In this platform, users create chat rooms for discussions around a topic of their choice. Organizers of these discussions can decide which listener in the room to be given the right to speak. To explore their experiences of persuading others and of being persuaded in Clubhouse discussions, we interviewed 16 Clubhouse users. One's credibility is important to the perceived persuasiveness of one's argument. In Clubhouse, one may establish their credibility through their profile pages where they introduce themselves such as their backgrounds, experiences, affiliations, passions, etc. Hence, our interviews also probed whether speakers' profile pages are used to check their credibility.

Published: October 2022

ABSTRACTThe study explores the use of COVID‐19 related apps for contact tracing deployed in New York State (NYS). The project seeks to understand potential differences in perception, adoption, or privacy concerns among racial and ethnic populations and across age groups. Using the Antecedent‐Privacy Concerns‐Outcomes (APCO) framework and the perceived usefulness construct, this study explores factors influencing the individual level adoption of these apps. Data collected from 120 Amazon Mechanical Turkers located in NYS was analyzed. The results indicate that race and gender are important factors to consider in expanding the Antecedent‐Privacy Concerns‐Outcomes (APCO) framework. Specifically, race impacted the perception of the seriousness of the pandemic, with Asians and Black being serious about the pandemic. Age played a role in privacy and security concerns. The youngest group of respondents, aged 18–24, did not have many privacy and security concerns about mobile apps. These results provided empirical results and evidence that can contribute to the expansion of the APCO model and help further the model's development.

Published: October 2022

RationaleThe high resolving power of the Orbitrap mass spectrometer in a high‐resolution accurate mass gas chromatography (HRAM‐GC‐MS) system provides greater selectivity and sensitivity for the identification and quantification of volatile analytes at low parts per billion (ppb) levels. Hence, it can be applied for the analysis of pharmaceutical impurities like N‐nitrosodimethylamine (NDMA) in metformin hydrochloride products (METs).MethodsDifferent METs extracted by a dichloromethane/aqueous system were analyzed by HRAM‐GC‐MS under softer electron ionization (EI) at 30 eV. The accurate masses of NDMA and its internal standard NDMA‐d6 were analyzed by full scan and targeted selected ion monitoring modes under 60 000 and 30 000 full width at half maximum at m/z 200, respectively. Data acquisition and processing were managed by Xcalibur and Trace Finder software, respectively.ResultsLimits of detection (LOD) and quantification (LOQ) at 10 and 20 ng/g were achieved, which is below the allowed daily intake of 32 ng/g. The mass errors measured from experimental data were within ±2 ppm of the theoretical values over a period of a week. Sample analysis showed that 180 out of 212 samples (85%) were below LOD and 15 out of 212 samples (7 %) were within LOD and LOQ. Only 17 samples (8%) were found to be above LOQ, comprising one active pharmaceutical ingredient (API), five immediate‐release METs and 11 extended‐released METs. Amongst these, seven extended‐release METs and one API exceeded the daily allowed intake, 32 ng/g.ConclusionsThe validated method has been successfully applied for NDMA analysis in various forms of METs. The method is rather straightforward without an additional clean‐up step. The scope can also be extended to other volatile impurities in finished pharmaceutical products.

AbstractBackgroundDespite robust weight loss and cardiometabolic benefit, lean mass loss following sleeve gastrectomy (SG) confers health risk. Bisphosphonates are a potential therapeutic agent for lean mass maintenance. Thus, our objective was to explore the effect of 6 months of risedronate (vs. placebo) on change in dual‐energy x‐ray absorptiometry (DXA)‐ and computed tomography (CT)‐derived lean mass metrics in the year following SG.MethodsTwenty‐four SG patients were randomized to 6 months of 150‐mg oral risedronate or placebo capsules (NCT03411902). Body composition was assessed at baseline and 6 months with optional 12‐month follow‐up using whole‐body DXA and CT at the lumbar spine and mid‐thigh. Group treatment effects and 95% confidence intervals (CIs) were generated from a mixed model using contrast statements at 6 and 12 months, adjusted for baseline values.ResultsOf 24 participants enrolled [55.7 ± 6.7 years (mean ± SD), 79% Caucasian, 83% women, body mass index (BMI) 44.7 ± 6.3 kg/m2], 21 returned for 6‐month testing and 14 returned for 12‐month testing. Six‐month weight loss was −16.3 kg (−20.0, −12.5) and −20.9 kg (−23.7, −18.1) in the risedronate and placebo groups, respectively (P = 0.057). Primary analysis at 6 months revealed a non‐significant sparing of appendicular lean mass in the risedronate group compared with placebo [−1.2 kg (−2.3, −0.1) vs. −2.1 kg (−3.0, −1.2)]; P = 0.20. By 12 months, the risedronate group displayed no change in appendicular lean mass from baseline [−0.5 kg (−1.5, 0.6)]; however, the placebo group experienced significantly augmented loss [−2.9 kg (−3.6, −2.1)].ConclusionsPilot data indicate that risedronate treatment may mitigate appendicular lean mass loss following SG. Further study is warranted.
Passive acoustic surveys reveal interactions between frugivorous birds and fruiting trees on a large forest dynamics plot

Published: October 2022

AbstractLong‐term vegetation plots represent one of the largest types of research investments in ecology, but efforts to interrelate data on plants with that on animals are constrained because of the disturbance produced by human observers. Recent advances in the automated identification of animal sounds on large datasets of autonomously collected audio recordings hold the potential to describe plant–animal interactions, such as between frugivorous birds and fruiting trees, without such disturbance. We deployed an array of nine autonomous recording units (ARUs) on the 400 × 500 m Bubeng Forest Dynamics Plot, in Xishuangbanna, southwest China, and collected a total of 1965 h of recordings across two seasons. Animal Sound Identifier (ASI) software was used to detect the vocalizations of five frugivorous bird species, and the probability of detection was related to the number of mature fruiting trees within a 50 m radius of the ARUs. There were more significant positive relationships than would be expected by chance in analyses that investigated bird/tree interactions across 3 months, both in the wet season and the dry season, as well as in short‐term analyses within the dry season months of October and November. The analysis identified 54 interactions between bird and tree species with significant positive relationships. Follow‐up observations of birds on the plot validated that such interactions were more likely to be observed than other interactions. We demonstrate that ARUs and automated voice identification can map the distribution and/or movement of vocal animals across large vegetation plots, allowing this data on animals to be inter‐related to that on plants. We suggest that ARUs be added to the standardized protocols of the plot network, leveraging their vast amount of information about vegetation to describe plant–animal interactions currently, and monitor changes in the future.
A Tandem Prins/Friedel‐Crafts Cyclization Strategy for the Stereoselective Synthesis of Hexahydro‐2H‐benzo[g]chromenes

Published: October 2022

AbstractA tandem Prins/Friedel‐Crafts cascade strategy has been developed for the synthesis of hexahydro‐2H‐benzo[g]chromene derivatives. Under action of equimolecular amount of BF3 etherate, δ,ϵ‐unsaturated alcohols and arylacetaldehydes are coupled to form oxocarbenium ion intermediates, which are captured by the alkene moiety through a favored six‐membered transition state. The Prins‐cyclization resultant tertiary carbenium ions undergo consecutive intramolecular Friedel–Crafts cyclization to create the tricyclic products. This process enables a tandem formation of three new chemical bonds in one single operation with high yields and stereoselectivity in most cases. When cyclic substituents are involved, a variety of spiro derivatives could also be synthesized successfully, which further proved the robustness of this methodology.

Published: October 2022

AbstractThis study aimed to explore whether zinc‐selenium tea has an curative effect on the cardiotoxicity induced by nonylphenol (NP), and to compare the effect of zinc‐selenium tea and green tea. After drinking of zinc‐selenium tea or green tea, compared with the control group, the left ventricular anterior wall became thinner, and the left ventricular end‐diastolic diameter increased, the anterior wall of the left ventricle became thin at the end of diastole in the NP group. The serum myocardial enzymes aspartate aminotransferase, creatine kinase, creatine kinase isoenzyme, lactate dehydrogenase, and α‐hydroxybutyrate dehydrogenase in the NP group were significantly increased, and the serum myocardial enzymes were significantly decreased after the intervention of zinc‐selenium tea. Proteins and mRNA expressions of Collagen I and Collagen III in the tea groups were lower than those in the NP group. In the green tea and zinc‐selenium tea intervention groups, the disorder and degree of myocardial fiber were alleviated to varying degrees. The disturbance, breakage, and inflammatory cell infiltration of myocardial fibers in zinc‐selenium tea and green tea groups were less than that of NP group. After tea intervention, collagen I and collagen III in the myocardium decreased. The intervention effect of zinc‐selenium tea was better than that of green tea. Zinc‐selenium tea and green tea could interfere with the cardiotoxicity indued by NP, which would alleviate the myocardial fibrosis by reducing expressions of collagen I and collagen III. Moreover, the curative effect of zinc‐selenium tea was better than that of green tea.
