Authors: Dahmer Payton L , Harrison Olivia L , Jones Cassandra K 
Published: October 2022

Abstract
A total of 350 weanling pigs (DNA 400 × 200; initially, 5.67 ± 0.06 kg BW) were used in a 42-day study with 5 pigs per pen and 14 replicate pens per treatment. At weaning, pigs were allotted to pens in a completely randomized design and pens of pigs were randomly assigned to one of five dietary treatments: 1) negative control (CON; standard nursery diet containing only 150 ppm Zn from trace mineral premix and no acidifier); 2) control diet with 3,000 ppm added zinc from ZnO included in phase 1 and 2,000 ppm added zinc from ZnO included in phase 2 (ZnO); 3) control diet with 0.70% formic acid (FA; Amasil NA; BASF, Florham, NJ); 4) control diet with 0.18% glycerol monolaurate (GML; Natural Biologics GML, Natural Biologics, Newfield, NY); and 5) control diet with a 1.0% blend of formic acid and glycerol monolaurate (FORMI; FORMI 3G, ADDCON GmbH, Bitterfeld-Wolfen, Germany). Pigs were fed treatment diets from d 0 to d 28 and were then fed a common diet from d 28 to d 42. From days 0 to 7, pigs fed ZnO or FORMI had increased (P = 0.03) ADG compared to pigs fed CON, with no difference in feed intake (P &gt; 0.05). Overall, pigs fed GML had reduced (P &lt; 0.0001) ADG compared with those fed the CON, ZnO, or FORMI diets. Fecal DM was evaluated from days 7 to 28 and there was a treatment × day interaction (P = 0.04). Pigs fed GML had a lower fecal DM % on day 7, but a higher fecal DM % on days 14 and 21; however, no differences in fecal DM were observed on day 28. Fresh fecal samples were collected from the same randomly selected pig on days 0 and 14 (70 pigs total;14 pigs per treatment) for analysis of fecal microbial populations using 16S rDNA sequencing. Dietary treatment did not significantly impact fecal microbiota at the phyla level, but pigs fed ZnO had an increased relative abundance (P &lt; 0.01) of the family Clostridiaceae. A blood sample was also collected from one pig per pen on days 0 and 14 for analysis of serum IgA, IgG, and TNF-α. There was no evidence that dietary treatment effected IgA, IgG, or TNF-α concentrations. The effect of sampling day was significant (P &lt; 0.05), where circulating IgA and TNF-α was increased and IgG was decreased from days 0 to 14. In summary, there is potential for a blend of formic acid and GML to improve growth performance immediately post-weaning without negatively impacting fecal consistency. Formic acid and GML alone or in combination did not impact fecal microbial populations or serum immune parameters.

AbstractRapid identification and isolation/quarantine of COVID-19 cases or close contacts, respectively, is a vital tool to support safe, in-person learning. However, safe isolation or quarantine for a young child also necessitates home confinement for at least one adult caregiver, as well as rapid learning material development by the teacher to minimize learning loss. The purpose of this study is to better understand barriers and supports to student home confinement. We conducted a mixed-methods study using focus group discussions and a self-administered online survey with parents and staff members from 12 elementary schools and childcare sites across San Diego County serving low-income and socially vulnerable families. Focus group participants reported that mental distress and loneliness, learning loss, childcare, food, income loss, and overcrowded housing were major barriers related to home confinement. The experiences described by FGD participants were prevalent in a concurrent community survey: 25% of participants reported that isolation would be extremely difficult for a household member who tested positive or was exposed to COVID-19, and 20% were extremely concerned about learning loss while in isolation or quarantine. Our findings suggest that there are serious structural impediments to safely completing the entire recommended course of isolation or quarantine, and that the potential for isolation or quarantine may also lead to increased hesitancy to access diagnostic testing.
Identifying positioning and storylines about mathematical modelling in teacher–student dialogues in episodes from two upper secondary classrooms
Authors: Berget Ingeborg Katrin Lid 
Published: October 2022

AbstractThe teaching and learning of mathematical modelling involve engagement in real-world situations and the mathematization of such situations. In this study, the communication between teachers and students in 13 lessons (0.75–1.5 hours each) in two Norwegian upper secondary classrooms is observed and recorded to explore how modelling is communicated and to evaluate the students’ agency in different episodes. Episodes in which a student takes initiative are analysed through the lens of positioning theory. An analytic tool is developed to explore the implementation of mathematical modelling in day-to-day activities by identifying the positioning and storylines of the speech/act in classroom episodes. It is found that the teacher facilitates students’ agency using everyday experiences when critiquing mathematical models. There are no possibilities found for students’ agency in the process of formulating a mathematical model. In these episodes, the storyline of mathematical modelling is one of finding the correct answer using given procedures, rather than engaging in real-world situations and making choices in the mathematization of such situations.

AbstractIntroductionAcute gastroenteritis is one of the most common causes of hospital admission in children. Treatment regimens differ depending on the pathogen. In our study, we aimed to evaluate the epidemiological and clinical features of pediatric patients whose gastrointestinal agents were detected by multiplex PCR.Materials and MethodsThe study included 131 pediatric patients who were followed up at Eskişehir Osmangazi University, Pediatric Department between January 2018 and December 2021.Gastrointestinal pathogens were detected in stool samples by multiplex PCR. The epidemiological and clinical features were reviewed retrospectively.ResultsA total of 203 gastrointestinal pathogens were detected from the stool samples of 131 cases. Of these cases, 56% were male and 44% were female. The mean age was 66 (2–204) months. The most common symptoms were diarrhea, fever, vomiting and abdominal pain. The pathogen detection rate was 69% by multiplex PCR. A single pathogen was detected in 85 (65%) cases and multiple pathogens were detected in 46 (35%) cases. The most common pathogens were enteropathogenic Escherichia coli (EPEC, 23%), Clostridium difficile (21%), norovirus (17%), rotavirus (15%), salmonella (12%) and enterotoxigenic E. coli (ETEC, 11%). Stool culture was positive in 16 (12%) cases and microscopic examination positive in 17 (13%) cases. Probiotic treatment was given to 119 (92%) cases and antimicrobial treatment (metroinidazole, ceftriaxone, azithromycin and oral vancomycin) to 34 (26%) cases. Of the cases, 56 (42%) had chronic disease, 40 (30%) had a history of previous antibiotic use and 17 (13%) had a history of hospitalization in the intensive care unit.ConclusionThe sensitivity of the multiplex PCR in the detection of acute gastroenteritis agents is higher than stool microscopy, stool culture and stool antigen tests. However, due to the inability to distinguish between colonization, carrier state and pathogenicity, it should be evaluated together with other diagnostic tests and clinical findings in order to determine whether the determined agent is pathogenic or not and in the regulation of antimicrobial therapy.

Abstract

Objective
The aim of the study was to investigate the pregnancy outcomes and possible influencing factors concerning complicated monochorionic (MC) multiple pregnancies undergoing selective fetal reduction using radiofrequency ablation (RFA).

Methods
This retrospective cohort study included 54 women with complicated MC multiple pregnancy who underwent selective fetal reduction using RFA at the Maternal and Child Health Hospital of Guangxi Zhuang Autonomous Region from January 2015 to March 2020. According to the indications for RFA, the 54 women were divided into three groups: complex complications (n = 30), structural anomalies (n = 18), and triplet pregnancy (n = 6). According to the gestational age for RFA, all patients were divided into three groups: 16–19+6 weeks (n = 17), 20–23+6 weeks (n = 17), and 24–26+6 weeks (n = 20). We analyzed the pregnancy outcomes (including the overall survival rate (OSR), gestational age at delivery, birth weight of newborns) and postoperative complications such as miscarriage, and intrauterine fetal death (IUFD) according to the indications and gestational age of reduction by using suitable statistical testing.

Results
The OSR was 83.3% (45/54). The mean ± standard deviation (SD) of gestation at the time of reduction was 21.6 ± 3.2 weeks. The GA at delivery was 34.0(32.0,37.5) weeks. The mean ± SD of newborns’ birth weight was 2118 ± 685 g. The overall rates of miscarriage, PROM, and IUFD were 9.3% (5/54), 7.4% (4/54), and 7.4% (4/54), respectively. According to the indications for reduction, the OSR for complex complications, structural anomalies, and triplet pregnancy groups were 83.3% (25/30), 83.3% (15/18), and 83.3% (5/6), respectively. Statistically significant differences were only found in the mean birth weight among the three groups (P < 0.05). No significant difference was found in the rate of miscarriage, and mean gestation at delivery among the three groups (P > 0.05). In the group with complex complications, the OSR of twin-to-twin transfusion syndrome, selective intrauterine growth restriction, twin reversed arterial perfusion sequence, and twin anemia polycythemia sequence were 66.7% (6/9), 93.3% (14/15), 80.0% (4/5), and 100.0% (1/1), respectively, with no significant difference among these groups (P > 0.05). According to the gestational age of reduction, the OSRs among the three groups were 82.4% (14/17), 76.5% (13/17), and 90.0% (18/20), respectively, and the rate of miscarriage, IUFD, and mean gestation age at delivery among these groups showed no significant difference (P > 0.05).

Conclusion
Selective fetal reduction by RFA is an important treatment method for complicated MC multiple pregnancy, although it may lead to complications like miscarriage, and IUFD. The indication of reduction seems to affect the pregnancy outcome. An optimal treatment plan should be selected according to the patient’s conditions in clinical practice.
The Controversies and Challenges in the Management of Twin Pregnancy: From the Perspective of International Federation of Gynecology and Obstetrics Guidelines
Authors: Liu Jingyu , Liu Quanrui , Zhao Jingya , Li Danlun , Zhou Yi 
Published: October 2022

Abstract
The rate of multiple pregnancy is increasing, mainly because of the widespread use of assisted reproduction techniques and families’ desire for twins. Twin pregnancy accounts for a higher risk of chromosomal abnormalities, structural malformations, and neonatal adverse events than singleton pregnancy. The presence of artery-vein anastomoses, unbalanced placenta sharing, and abnormal cord insertion in monochorionic twins is associated with twin complications such as twin-to-twin transfusion syndrome, selective intrauterine growth restriction, and twin anemia polycythemia sequence. Although many guidelines and studies have established and improved the processes about the antenatal surveillance and management of twin pregnancy, they also raise more controversies and challenges. This review aims to highlight the international consensus on the antenatal care of twin pregnancies and analyze the controversies and predicaments based on the published International Federation of Gynecology and Obstetrics guidelines and research.

Published: October 2022

PurposeThis study aimed at investigating negative past experience (NPE), symbolic incongruity and ideological incompatibility on celebrity brand hate (CBH) within the arts marketing sector.Design/methodology/approachAnchored on the self-congruity theory (SCT), the study is based on two studies with 618 hip-life music (HLM) listeners in Ghana (Study 1 = 340 face-to-face participants; study 2 = 278 online participants), who responded to 20 celebrities they hate. The study validates Hegner et al.'s (2017) product brand hate (BH) model in the arts sector utilizing the structural equal modeling in testing the research hypotheses.FindingsThe study found that negative past experience, symbolic incongruity, and ideological incompatibility significantly influences CBH. Furthermore, CBH significantly influences celebrity brand avoidance (CBA) and negative word-of-mouth (NWoM), brand retaliation, private complaint and brand switching. Nevertheless, CBH had no significant influence on CBA in the second study. In all, BH had the strongest effects on NWoM for products in Hegner et al. (2017) model, whereas in our model BH strongly impacts on brand retaliation for celebrities (i.e. people).Practical implicationsThe study provided evidence to marketing scholars, celebrity image managers and brand professionals, on critical factors to consider in building and sustaining celebrity brands as viable currencies for economic leveraging within the arts industry.Originality/valueThough BH has received academic recognition, little is known about the concept of CBH and its outcomes in the arts marketing literature.
Integrative literature review on employee turnover antecedents across different generations: commonalities and uniqueness
Authors: Climek Michael , Henry Rachel , Jeong Shinhee 
Published: October 2022

Purpose
The purpose of this study is to synthesize the current turnover literature that has investigated the nonfinancial antecedents of turnover intention across generations. This paper provides an integrative and analytical review of prior empirical studies with two research questions: What nonfinancial factors influencing employee turnover have been empirically identified across different generations? and What generational commonalities and uniqueness exist among the turnover antecedents?

Design/methodology/approach
To identify nonfinancial antecedents of employee turnover, an integrative literature review that allows a systematic process of searching and selecting literature was conducted. While synthesizing the antecedents identified in the articles, the authors were able to categorize them at three different levels: individual, group and organizational

Findings
The authors discuss each antecedent according to three categories: individual, group and organizational levels. Based on the findings from the first research question, the authors further explore the commonalities and uniqueness among three generations (i.e. Millennials, Generation X and older workers).

Originality/value
This study found both generational commonalities and uniqueness in terms of turnover intention antecedents. Based on the findings of the study, the authors discuss how to facilitate these common factors across all generations as well as considering the factors unique to each generation. Differentiation within organizations regarding retention strategies should yield positive results for both employees and organizations.
Information literacy instruction in university libraries of Islamabad, Pakistan: a study of librarians’ perceptions, practices, barriers, and strategies
Authors: Moin Ud Din Ghulam , Mairaj Muhammad Ijaz , Sheikh Arslan 
Published: October 2022

PurposeThis paper aims to measure the perceptions of librarians about information literacy (IL) instruction, their current IL practices and the problems they face while offering IL instructional programs in public and private sector university libraries in Islamabad, the capital city of Pakistan.Design/methodology/approachA quantitative research design was adopted, and a survey was carried out for this study to collect the data through an online questionnaire for the university librarians. All librarians (a total of 120) were approached to collect the data, of whom 92 (76.6%) responded to the survey.FindingsThe findings reveal that the librarians working in the university libraries of Islamabad are aware of the significance of IL instruction to fulfil the information needs of their library users. A majority of the librarians indicated having adequate skills to offer IL instruction. Moreover, the majority of the librarians are offering IL instruction to users at their respective universities. However, some of the barriers affecting IL instruction programs were also reported including the absence of IL instruction courses in the library and information science (LIS) curriculum, a shortage of trained library professional staff to provide IL instruction, a lack of commitment among librarians for IL instruction, a lack of training opportunities for librarians and a lack of interest from library users. These obstacles have a negative effect on IL instruction in the university libraries of Islamabad. Therefore, this study suggests that librarians are needed to take several necessary steps to overcome these obstacles to achieve the best results in IL instruction programs.Originality/valueThis study presents a picture of the status of IL skills, current practices and barriers to offering IL instruction in the university libraries of Islamabad. This research bridges the gap in the existing literature and will help to create awareness about the importance of IL skills among LIS professionals in Pakistan. Moreover, the findings of this study will help encourage librarians for the enhancement of IL instruction services in university libraries of Islamabad in particular and Pakistan in general.
An exploratory study of university librarians’ perceptions on causes and deterrents of plagiarism: a Pakistani perspective
Authors: Mansoor Faiqa , Ameen Kanwal , Arshad Alia 
Published: October 2022

Purpose
The role of academic libraries in dissemination of information and facilitating research of academic community is well-established world over. However, a significant role of libraries in ensuring fair use of information to promote an ethical research culture at the higher education institutes is also flourishing. This study aims to explore the perceived causes of unethical use of literature by university scholars and deterrents to plagiarism in universities of Pakistan.

Design/methodology/approach
The design of the study was qualitative, and interviews were conducted on nine university library heads in Pakistan who were officially administrating anti-plagiarism (Turnitin) software service at their universities and were providing “similarity index certification” of PhD and MPhil research work through the software. They were purposively selected for the interviews because of their direct interaction with the researchers and faculty on matters of information searching as well as its ethical use. The study is based on PhD thesis work of the first author.

Findings
The findings of the study depicted that conceptual unawareness of plagiarism, lack of information skills, socio-cultural factors and weak policies were the prime reasons for unethical research practices among graduate scholars. Participants were positive that a role of university library in combating plagiarism through provision of anti-plagiarism software and guidance could prove more beneficial for both the researchers and libraries.

Originality/value
Multiple studies have been conducted, in and out of south Asian region, to gather the views of the students and faculty on the matters of academic misconduct. However, no study was found presenting the views of the other stakeholders in promotion of academic integrity. To the best of the authors’ knowledge, this study is first of its kind in South Asian context and provided observation-based views of a group of university library heads who are also administrating anti-plagiarism service in their universities on the causes and deterrents to plagiarism.
A novel space/time integration technology via altogether different space and time stepping methods for nonlinear first-order systems
Authors: Tae David , Tamma Kumar K. 
Published: October 2022

Purpose
The purpose of this paper is to describe a novel implementation of a multispatial method, multitime-scheme subdomain differential algebraic equation (DAE) framework allowing a mix of different space discretization methods and different time schemes by a robust generalized single step single solve (GS4) family of linear multistep (LMS) algorithms on a single body analysis for the first-order nonlinear transient systems.

Design/methodology/approach
This proposed method allows the coupling of different numerical methods, such as the finite element method and particle methods, and different implicit and/or explicit algorithms in each subdomain into a single analysis with the GS4 framework. The DAE, which constrains both space and time in multi-subdomain analysis, combined with the GS4 framework ensures the second-order time accuracy in all primary variables and Lagrange multiplier. With the appropriate GS4 parameters, the algorithmic temperature rate variable shift can be matched for all time steps using the DAE. The proposed method is used to solve various combinations of spatial methods and time schemes between subdomains in a single analysis of nonlinear first-order system problems.

Findings
The proposed method is capable of coupling different spatial methods for multiple subdomains and different implicit/explicit time integration schemes in the GS4 framework while sustaining second-order time accuracy.

Originality/value
Traditional approaches do not permit such robust and flexible coupling features. The proposed framework encompasses most of the LMS methods that are second-order time accurate and unconditionally stable.
