IntroductionWe encountered an extremely rare case of a vesicocutaneous fistula due to vesical diverticulitis with stones.Case presentationA 78‐year‐old male patient presented to our department with complaints of suppurative discharge in the suprapubic area. Computed tomography revealed an enlarged prostate, a vesical diverticulum with stones located on the ventral side, and an aberrant connection between the anterior bladder wall and the external surface of the skin. The patient was diagnosed with a vesicocutaneous fistula due to vesical diverticulitis and was successfully treated with a multidisciplinary approach including vesical diverticulectomy with stone removal and nonviable tissue debridement. The patient continues to receive regular outpatient follow‐ups with urinary catheter changes.ConclusionVesicocutaneous fistulas due to vesical diverticulitis with stones are extremely rare. We should be aware that a vesical diverticulum with stones located on the ventral side might pose a high‐risk factor for the formation of a vesicocutaneous fistula in elderly patients.

AbstractObjectivesTo evaluate the sonographic features of secondary involvement of skin and subcutaneous tissues by hematologic malignancies.MethodsA review of the ultrasound and pathology databases yielded 10 cases with 13 skin and subcutaneous tissue lesions secondary to hematologic neoplasms, which were confirmed by pathology. We used ultrasound to assess the number, location, size, depth of involvement, echogenicity, and vascularity of the lesions.ResultsThe study involved five male and five female patients, including four leukemia, two multiple myeloma, and four lymphoma patients. The average age was 45 years (17–66 years). Three patients presented with one lesion, four with two lesions, and three with more than two lesions. All the lesions were located in the trunk and extremities. The lesions ranged from 1.2 to 8.3 cm in size. A total of 10 lesions involved subcutaneous fat tissue. A total of 10 lesions displayed hypoechoic foci within a hyperechoic background, and three appeared hypoechoic, and most of them exhibited abundant vascularity (12 of 13 lesions).ConclusionsSecondary involvement of skin and subcutaneous tissues by hematologic malignancies often present with multiple palpable masses showing the following ultrasound features: (1) subcutaneous fat infiltration, (2) hypoechoic foci with a hyperechoic background, and (3) abundant vascularity.
Facile Catalyst‐Free Approach toward Fully Biobased Reprocessable Lignin Thermosets
Authors: Buzoglu Kurnaz Leman , Bension Yishayah , Tang Chuanbing 
Published: October 2022

AbstractReprocessable and biobased thermosets are prepared from two renewable feedstocks, lignin and polyamine (Priamine 1071). Lignin is oxidized to produce polycarbonyl and further reacts with polyamine to form a crosslinked network of imines. The thermoset materials are formed under heat and pressure in the absence of any catalysts. The mechanical strength and thermal properties of thermosets are tunable by changing feedstock ratios. The dynamic imine crosslinks can be associatively reformed.

Published: October 2022

AbstractHigh‐damping acoustic composites with unique sound insulation feature is reported, demonstrating surprisingly stable soundproof properties over a wide bandwidth of frequency (63–6300 Hz) with good mechanical properties. The extraordinary acoustic properties are attributed to the multiscale synergy of lamellar and hollow structures by multifillers adding. The acoustic composites are designed and fabricated through a low‐temperature one‐time rubber mixing process using nitrile butadiene rubber(NBR), chloroprene rubber (CR) as matrix and mica powder (MP), hollow glass beads (HGB), and montmorillonite (MMT) as multifillers. The soundproof mechanism is discussed in detail. Results indicate that the synergism of damping and sound absorption behaviors in the composition has a considerable impact on the acoustic characteristics, which can be controlled by the blending ratio of NBR/CR matrixes and the multiscale structures of MP/HGB/MMT multifillers. The designed multifillers acoustic composites can adapt to broadband engineering noise control including walls in express train constructions, panels of vessel or aircraft cabins, and large transportation pipelines.

Published: October 2022

AbstractIn this study, a simple photocuring method is proposed for preparing PDMS elastomers using a homogenous poly(dimethylsiloxane) (PDMS) solution in tert‐butyl acrylate (tBA) as an alternative way of mechanically blending two kinds of PDMS respectively containing vinyl and hydridosilyl groups over a platinum catalyst. Poly(dimethylsiloxane‐co‐methylvinylsiloxane) (PDMSc) with 30 mol% of vinyl moieties is synthesized. The functionalized PDMS is estimated to be soluble in tBA from theoretical calculations of solubility parameters of PDMS and several liquid monomers. The PDMS solution is satisfactorily photocured under a conventional photoinitiator. Initial modulus and strain of the photocured films increase from 144 to 552 MPa and decrease from 3.96 to 1.84, respectively, as the tBA content rises from 5 to 30 wt%. They are extremely transparent in a visible region (T > 94%) regardless of the amount of tBA. The unreacted vinyl groups in PDMSc are inter‐ or intrareacted near 200 °C and γ‐hydrogen transfer reactions from the tert‐butyl groups in poly(tert‐butyl acrylate) occur over 250 °C. One of the photocrosslinked films exhibits outstanding performance as an electroactive polymer in application. In essence, this study will initiate a new methodological research into provision of PDMS elastomers using an easily formulated photocrosslinkable PDMS solution.
Virtual is so real! Consumers' evaluation of product packaging in virtual reality
Authors: Branca Generoso , Resciniti Riccardo , Loureiro Sandra Maria Correia 
Published: October 2022

AbstractVirtual Reality (VR) is shaping all human activities, and with the advent of the metaverse, buyers are going to experience new ways of doing shopping. What would happen if consumers will be asked to assess a product's attribute, i.e., packaging, in a virtual environment, instead of being able to physically hold the product, like in a traditional purchasing process? The aim of this study is to analyze consumers' evaluation of packaged products in immersive VR, manipulating packaging structural and haptic cues, and clarify potential differences with the consumers' responses in the real life. We conducted two focus groups (Study 1), with 16 participants, a mixed design experiment (Study 2), involving 167 consumers, to analyze consumers' attitudes, and a choice‐based conjoint analysis (Study 3), with 41 individuals, to study actual choice behavior. The main findings reveal that consumer behavior in VR is consistent with everyday life, except for minor variations. VR proves to be an efficient and rigorous research environment, also suitable for testing sensory cues and non‐tangible attributes. Finally, the article suggests managers can effectively use VR for product and packaging development, through a more sustainable process that requires fewer resources and time compared to traditional tests.
Autophagy in non–immune‐mediated rhabdomyolysis: Assessment of p62 immunohistochemistry

Published: October 2022

AbstractIntroduction/Aimsp62 immunochemistry (IHC) has been shown to aid diagnosis with distinct patterns of muscle fiber staining observed in some inflammatory, hereditary, and degenerative myopathies, such as immune‐mediated necrotizing myopathy (IMNM). The pattern of p62 staining may help narrow the pathological differential diagnosis of rhabdomyolysis. However, there is a lack of information on the pattern of p62 IHC in non–immune‐mediated rhabdomyolysis. In this study we aim to describe histopathological findings in non–immune‐mediated rhabdomyolysis, with particular emphasis on the pattern of p62 IHC.MethodsWe retrospectively reviewed the histopathological features of patients with a confirmed diagnoses of non–immune‐mediated rhabdomyolysis referred to our center.ResultsFive patients were identified. Rhabdomyolysis was determined to be due to statin‐associated toxicity in three patients, alcohol overuse in one patient, and intensive exercise in one patient. All patients showed increased numbers of necrotic and regenerating muscle fibers. Diffuse and finely granular sarcoplasmic positive p62 staining was present in scattered non‐necrotic muscle fibers in all patients.DiscussionDisturbance of autophagy appears to be a common mechanism in non–immune‐mediated rhabdomyolysis. Our results show p62 IHC is sensitive but lacks specificity. Therefore, the pattern of p62 staining does not distinguish non–immune‐mediated rhabdomyolysis from histopathologically similar IMNM.

AbstractThe impact of insecure attachment on hoarding behavior (HB) has been supported by empirical evidence. However, scant literature has focused on how anthropomorphism (attributing human‐like traits, characteristics, or emotions to nonhuman objects) and hoarding beliefs (motivations for ownership) affect the relationship between insecure attachment and HB, especially among Chinese adolescents. Using a cross‐sectional study, we reserved 903 participants (561 males, 342 females, M = 20.20, SD = 1.85, age range = 18–24 years) to complete self‐report questionnaires about close relationships, anthropomorphism, saving beliefs, and saving inventory to investigate the mediating role of anthropomorphism and the moderating role of hoarding beliefs in the relationship between insecure attachment and HB. Attachment anxiety and avoidance had a positive relationship with HB, and anthropomorphism is a mediating factor in the association between attachment anxiety and HB. In addition, hoarding beliefs moderated the relationship between attachment anxiety and HB. This study further elaborated on the relationships between insecure attachment, anthropomorphism, hoarding beliefs, and HB, which might shed some light on adolescent clinical interventions.

AbstractPurposeAcute pancreatitis (AP) is a frequently encountered adverse drug reaction. However, the validity of diagnostic codes for AP is unknown. We aimed to determine the positive predictive value (PPV) of a diagnostic code‐based algorithm for identifying patients with AP within the US Veterans Health Administration and evaluate the value of adding readily available structured laboratory information.MethodsWe identified patients with possible AP events first based on the presence of a single hospital discharge ICD‐9 or ICD‐10 diagnosis of AP (Algorithm 1). We then expanded Algorithm 1 by including relevant laboratory test results (Algorithm 2). Specifically, we considered amylase or lipase serum values obtained between 2 days before admission and the end of the hospitalization. Medical records of a random sample of patients identified by the respective algorithms were reviewed by two separate gastroenterologists to adjudicate AP events. The PPV (95% confidence interval [CI]) for the algorithms were calculated.ResultsAlgorithm 2, consisting of one ICD‐9 or ICD‐10 hospital discharge diagnosis of AP and the addition of lipase serum value ≥200 U/L, had a PPV 89.1% (95% CI 83.0%–95.2%), improving from the PPV of algorithm 1 (57.9% [95% CI 46.8–69.0]).ConclusionsAn algorithm consisting of an ICD‐9 or ICD‐10 diagnosis of AP with a lipase value ≥200 U/L achieved high PPV. This simple algorithm can be readily implemented in any electronic health records (EHR) systems and could be useful for future pharmacoepidemiologic studies on AP.

Authors: Lischer‐Katz Zack , Haines Jelina , Vamanu Iulian 
Published: October 2022

AbstractThis panel, co‐sponsored by ASIS&T SIG‐VIS (Visualization, Images, & Sound) and SIG‐DL (Digital Libraries), has two purposes. First, it briefly discusses panelists' recent research projects on visual forms of knowledge production and documentation. Their approaches involve collecting visual forms of data or studying contexts in which information practices involve visual information formats or regimes of graphical information creation. Second, this panel draws attention to the importance of dialogic engagement and acknowledgment of the role of the embodied researcher as a critical methodological agent in generating research data related to visual practices. This central role of the researcher in visual research foregrounds ethical and epistemological aspects of their positionality. In particular, panelists will discuss the ethical challenges of information studies research that involves Indigenous knowledge communities. This panel will engage the audience in a discussion on the role played by a researcher's positionality in shaping qualitative information research methodologies and will discuss how the generation of visual forms of data and the study of visual information practices pose particular challenges for information studies research.

Authors: Byun Mimi , Evans Sarah , Herman Bernease , Aragon Cecilia , Rojas‐Ponce Diana 
Published: October 2022

ABSTRACTThis exploratory study investigates the use of game development as a speculative activity to teach data science ethics incorporating the Directed Research Groups (DRG) format, that decentralizes classroom dynamics, emulates real‐life working environments, and offers students creative choices driven by their own interests. This DRG focuses on creating a video game addressing an ethical issue in data science. Working in groups of peers from diverse backgrounds and education allows for multiple meanings to occur in a team‐based learning environment. This enriches the students' engagement with the material and by creating video games that have an impact on these social issues, itt also grounds their role as an active change agent for a future they envision.
A Preliminary Analysis of Geography of Collaboration in Data Papers by S&T Capacity Index
Authors: Chen Pei‐Ying , Li Kai , Jiao Chenyue 
Published: October 2022

ABSTRACTGeography is one of the defining factors in scientific collaboration. Despite the voluminous evidence for how geographical proximity shapes the formation of collaboration in research articles, it has been rarely examined in the emerging genre of data papers, one that describes research data and has enjoyed growing attention in the data‐driven paradigm of research. This poster presents preliminary findings from our project that aims to evaluate the geographical dynamics behind the production of data papers. We analyze how researchers from different countries collaborate with one another using 6,821 data papers published in Scientific Data and Data in Brief between 2014 and 2020. We found that data papers rely heavily upon domestic collaboration and the collaboration pattern largely mirrors that of research articles, although some distinctiveness was also observed. We discuss future work in conclusion, with the ultimate goal of opening a more meaningful conversation about the relationship between the data‐driven paradigm and knowledge production.
Predicting Search Task Difficulty through a Discrete‐Time Action Log Representation on Spectrum Kernel
Authors: Gacitúa Daniel , González‐Ibáñez Roberto 
Published: October 2022

ABSTRACTPredicting perceived difficulty on a web search task is an open problem in the interactive information retrieval field. A common approach to tackle it, is through features obtained from full search sessions, which are then used to train classification models. In this poster we attempt to predict perceived task difficulty at different stages of the search process. To do so, we use the spectrum kernel for support vector machine (SVM) classification. Our preliminary results suggest that by using behavioral data from the first query segment, it is possible to provide timely classifications of whether a search task is perceived as hard or easy.

Revisiting Connotations of Digital Humanists: Exploratory Interviews
Authors: Ma Rongqian 
Published: October 2022

ABSTRACTThis ongoing study revisits the connotations of “digital humanists” and explores the reasons why a researcher does or does not self‐identify as a digital humanist. Building on semi‐structured interview data collected from fourteen researchers and practitioners engaging in digital humanities (DH) projects, this poster illustrates researchers' various understandings of “digital humanist” as a term and research identity and highlights the complexity of “digital humanists” as a research community. This study contributes to DH scholarship with insights into the collective imaginations of the “digital humanist” as a research community one decade after the early attempts. Findings of this research study also facilitate a more thorough, timely, and dynamic discussion of the major workforce in digital humanities, potentially paving the way for future research on labor and collaboration in the DH research domain.
Give or Take?: Conceptualizations of Data and Its Creation in Information Science
Authors: Ridenour Laura , Moulaison‐Sandy Heather 
Published: October 2022

ABSTRACTIn information science, what data itself is, how it is defined, and the distinctions between data and information are unclear, yet data is a foundational construct at the heart of the research enterprise. This poster probes the question of how data is conceptualized in information science through an analysis of works by Jonathan Furner, Birger Hjørland, and Michael Buckland, who have contributed substantially to this critical issue. It finds that notions of the nature of data vary widely, and are often contradictory. Complexities are identified in the approach to data as both documents and as records. In the process of this analysis, it identifies the essential question of whether [research] data is given or taken: Is data found/identified by the researcher, or is it created? Arguments for both approaches are fleshed out, providing a basis for further work in information science in this essential space.

This paper describes the design of such an approach, entitled Sangam: Prompts for Discussions, Decision Making, and Design Activities that Respect Newcomer Communities and their Data. Grounded in empirical research, Sangam is a set of physical cards that prompt reflection on and discussion of ethical complexities that arise when coordinating immigration and settlement services in Canada. This report describes the process of designing the Sangam cards, staying true to the project's research findings while also leaving space for interpretive flexibility.
Are Virtual Reference Services Color and Gender Blind? Service Equality Revisited
Authors: Vladoiu Megan , Fichman Pnina 
Published: October 2022

ABSTRACTFollowing the rise of the Black Lives Matter Movement in 2020, there has been an increased focus on racial equality in library services, including recent modifications of the ALA Code of Ethics. Online library services may eliminate race‐based service discrimination by obscuring the racial identity of the patron. However, racial assumptions based on patrons' names can lead to online discrimination. While prior research shows mixed results, we examine if there is evidence of racial bias in virtual reference in American academic libraries. Initial findings based on content analysis of 946 responses from 255 libraries suggest that Tyrone Jackson received better service than others did.
Paving the Speedway to the IT Harbor: How Chinese Programming Boot Camp Prepares Chinese Migrants for IT Jobs in the United States
Authors: Tian Huixin 
Published: October 2022

ABSTRACTIn recent years, Chinese migrants have become one primary source of computing professional labor in the United States. Within the Chinese migrant community, the computing profession was depicted as a new framework of success and a harbor to ease the stress caused by precarious immigration status. To successfully obtain a job in the IT industry, many Chinese migrants turned to the Chinese programming boot camp (PBC) for professional training in programming, which made Chinese PBC the intermediary between Chinese migrant professionals and the American companies demanding skilled programmers. In this research based on qualitative interviews with the founders, employees, and clients, I illustrated how Chinese PBC constructed computing knowledge into a set of techniques and skills to solve and present algorism problems. I interpreted this knowledge construction in the context of racialized and mystified computing profession in the Chinese migrant community.
