Mongeon, P., Siler, K., Archambault, A., Sugimoto, C. R., & Larivière, V. (2021). Collection development in the era of big deals. College & Research Libraries, 82(2), 219–236. https://doi.org/10.5860/crl.82.2.219
Abstract
Objective – (1) Present a method of journal appraisal that combines reference list, article download, and survey data. (2) Gauge journal usage patterns across selected universities.
Design – Analysis of reference lists, article downloads, and survey data.
Setting – 28 Canadian universities.
Subjects – 47,012 distinct academic journal titles.
Methods – Download data for the 2011-2015 period was sourced from standard Journal Report 1 (JR1) usage reports as supplied by the vendors. Download figures were summed for journals that were available through multiple platforms. Reference list data (i.e., the number of times documents published in each journal were cited by authors affiliated with a participating institution) was sourced from Clarivate Analytics’ Web of Science, limiting for the years 2011-2015. An unknown number of researchers at 23 of the 28 participating universities were invited by email to complete a survey. The survey asked respondents to list the scholarly journals they considered essential for their research and teaching (up to 10 journals for each purpose).
The three datasets (download, reference list, and survey data) were then merged. Duplicates and non-academic journals were removed. Journals were then grouped into broad discipline areas. A list of “core journals” (p. 228) was created for each institution. These journals produce 80% of downloads, 80% of citations, or 80% of survey mentions at each institution. A journal only had to reach the threshold in one category (i.e., in either downloads, citations, or mentions) to make it onto the core journals list. A “low” (p. 228) survey response rate meant “one mention [was] generally enough" (p. 228) for a journal to be classified as core.
Main results – Fewer than 500 titles (n=484, ~1%) made it to the core journals list at all 28 universities. Two thirds (66%, n unknown) of journals did not make it onto the core list of any university. Of the journals deemed to be core, most (60%, n unknown) were shared across all institutions. On average, platforms from not-for-profit organizations and scientific societies contain a higher proportion of core journals than for-profit platforms. Notably, 63.6% of Springer journals, 58.9% of Taylor & Francis journals, and 45.8% of Elsevier’s journals do not appear on the core journal list of any university.
Conclusion – Libraries should consider ways to share resources and work more cooperatively in their negotiations with publishers. Further, libraries may be able to cancel entire journal bundles without this having a “sizable” (p. 233) impact on resource access.

A Review of:
Lundstrom, K., Fagerheim, B. & Van Geem, S. (2021). Library teaching anxiety: Understanding and supporting a persistent issue in librarianship. College & Research Libraries, 82(3), 389-409. https://doi.org/10.5860/crl.82.3.389
Abstract
Objective – To determine academic librarians’ attitudes towards their teaching, how teaching anxiety manifests itself, and how teaching anxiety affects these attitudes.
Design – Online Survey.
Setting – The survey was distributed through various library science listservs.
Subjects – Any library staff with a teaching component in their role were invited to respond. There was a total of 1,035 initial responses.
Methods – The survey questions were based on a previously published survey about teaching anxiety by Davis (2007). However, the survey for this study added questions about formal and self-diagnosis of other types of anxieties, physical and psychological anxiety symptoms, and how teaching anxiety impacts other areas of the respondents’ lives. There were also questions on potential supports to reduce teaching anxiety, as well as potential barriers to these supports.
Main Results – It was found that approximately 65% of respondents experience teaching anxiety. Approximately 40% of those respondents were formally diagnosed with anxiety, and approximately 42% were self-diagnosed. There was a significant association between a formal diagnosis of anxiety, and teaching anxiety. There were also significant associations between past training, preparation, and teaching anxiety, with anxiety occurring less with increased training and preparation.
Conclusion – Teaching anxiety is a significant issue among library staff. Supports in the form of workshops on teaching as well as coping with anxiety can possibly help to reduce this phenomenon.
“Hi, Madam, I have a small question.” Teaching QM online: Guide to a successful cross-cultural master-course
Authors: Ryen Anne 
Published: January 2022

A few years ago Centre of Development Studies at my Faculty, Faculty of Economics and Social Sciences, started an online Master’s Programme in Development Management. The programme was implemented by a network of universities from the North (University of Agder/UiA) and the South (Sri Lanka, Tanzania, Ethiopia, Uganda, Ghana) recruiting students from across the world. The evaluation is very positive characterising it as a big success. I will now look into one particular element of this study, teaching the qualitative methodology (QM) courses with a special focus on the South context. Each course QM included has been sectioned into modules based on a variety of students` activities including student-student and student-tutor/teacher interaction, plus a number of hand-ins across topics and formats. Evaluation of the students` performance is based on both online group activity and written material submitted either into the individual or the group portfolio. My focus is twofold. First, how did we teach qualitative methodology and how did that work? Second, what about the contemporary focus on neo-colonial methodology and our QM courses? In a wider perspective the study is part of foreign aid where higher education is a means to transfer competence to the South. As such this study works to enable and to empower people rather than being trapped in the old accusation of sustaining dependency (Asad 1973, Ryen 2000 and 2007a). This study then is embedded in a wider North-South debate and a highly relevant illustration of the potentials, success and hazards, inherit in teaching QM.
Evaluation of Thromboembolism According to Mutation Status in Patients with Essential Thrombocytosis; Single-Center Experience
Authors: BATGİ Hikmettullah 
Published: January 2022

ABSTRACT
Aim: The presence of Janus kinase 2 (Jak2) mutation in essential thrombocytosis (ET) patients is associated with an increased risk of thrombosis, while the presence of calreticulin (Calr) mutation is associated with a decrease in thrombosis risk. The aim of this study is to compare patients with mutation (Jak2, Calr, myeloproliferative leukemia virus oncogene [Mpl]) and non-mutation (triple-negative) patients in terms of the development of thromboembolism.
Methods: 95 patients who were followed up with the diagnosis of ET between 2009 and 2020 were included in this study. The clinical characteristics, laboratory results, and mutation status of the patients were analyzed retrospectively, based on the patients’ files. The patients in mutation positive (Jak2, Calr, Mpl) group a, only jak2 mutation-positive group b, and triple-negative (Jak2, Calr, Mpl negative) group c were compared.
Results: The median age of ET patients was 53 years (18-91). The Jak2 mutation was found positive in 42% (n:40) of the patients with ET. 4 patients (4%) were calr mutation-positive, but mpl mutation was not detected. 51 patients (54%) were triple-negative. A total of 22 (23%) patients had a thrombotic event at diagnosis and follow-up. Thrombotic events were detected in 27.5% (11/44) of the patients with positive Jak2 mutation and in 21.5% (11/51) of the patients with triple-negative. No thrombotic event was detected in 4 patients with a positive calr mutation. No statistically significant difference was found for thrombotic events in mutation-positive patients compared with triple-negative patients (p = 0.7). No statistically significant difference was found in terms of white blood cell count, thrombocyte count and spleen size examined at the time of diagnosis. When compared in terms of hemoglobin, age and gender distribution (male / female), the difference was found statistically significant in those with positive mutation (p = 0.001 *, p = 0.001 *, p = 0.03*).
Discussion and Conclusion: The results of this study showed that Jak2V617F gene mutation is an important finding for diagnosis and complications in patients with ET, and its presence increases the risk of thrombosis development. The presence of calr mutation reduces the risk of thrombosis and appears at an earlier age than Jak2V617F mutation. Thrombosis risk in triple-negative ET patients is similar to the one in patients with Jak2V617F mutation.

AIM: The aim of this study was to investigate the relationship between comorbid diseases, vitamins levels and sleep quality of patients undergoing polysomnography (PSG) in a sleep clinic.
MATERIAL AND METHODS: Fifty-four patients who underwent PSG between January 2018 and December 2018 at Bolu Abant İzzet Baysal Training and Research Hospital Sleep Clinic were included in the study. PSG measurements were performed in the sleep clinic following appropriate preparatory procedures.
RESULTS: Of the study group, 41 (78.8%) were male and 11 (21.2%) were female. The mean age was 49.25 ± 12.77 years. The number of sleep apneas (p=0.013), central apnea (p=0.037), apnea / hypopnea index (p=0.026) and RDI (p=0.021) were higher in patients with diabetes melllitus (DM). It was found that REM sleep time was shortened in patients with hypertension (HT) (p=0.021) and patients with CAD (p=0.013). There was a positive weak correlation between vitamin D levels and stage 2 sleep duration (p=0.032, r = 0.309). As folate levels (p=0.039, r =-0.305) and vitamin B12 levels (p=0.035, r=-0.305) increased, arousal index values decreased.
CONCLUSION: HT and CAD have very limited effects on sleep. In addition, DM most negatively affected sleep parameters in this study. It was also found that the evaluated vitamin levels affect sleep only very limited in some parameters.
AKUT BRONŞİYOLİT

Published: January 2022

Akut bronşiyolit (AB), bebekleri etkileyen alt solunum yolunun viral bir enfeksiyonudur. En sık etkenin Respiratory syncytial virus olduğu bilinmektedir. Tanı, tipik olarak üst solunum yolu enfeksiyonu ile başlayıp alt solunum yoluna ilerleyen klinik bulgular ve bunlara eşlik eden muayene bulguları ile konulur. Akut Bronşiyolit, benzer klinik tabloyu yapan diğer akut, kronik veya tekrarlayan bronşiyolit yapan durumlardan ayrılmalıdır. Hastalık ve maliyetleri nedeniyle tedaviyi standartize etmek için birçok rehber yayınlanmıştır. Hastanın oksijenasyon ve hidrasyonunu dengelemek tedavinin temelini oluşturur. Kanıtlar ve kılavuz önerileri, ilk bronşiyolit atağı olan bebeklerde, bronkodilatör veya kortikosteroid kullanımının fayda sağlamadığını göstermektedir. Hipertonik salin gibi, diğer tedavilere ilişkin kanıtlar artmaktadır. Hipertonik salinin yatan hastalarda taburculuğu hızlandırdığı gösterilmiştir. Şiddetli hastalığı olan bebeklerde yüksek akım oksijen tedavisi ve sürekli pozitif hava yolu basıncı kullanımının mekanik ventilatör ihtiyacını azaltmakta rol oynadığı düşünülmektedir.
Bu derlemenin amacı güncel literatür eşliğinde AB’in tanı, tedavi ve korunma yaklaşımlarının gözden geçirilmesi ve bu sayede hekimlere ortak yaklaşım sergileyebilmeleri için destek olmaktır.

Published: January 2022

Abstract
Modified bentonites for anti–seepage system application has been attracting global attentions. At the same time, the performances of modified bentonite containing retardation barrier exposed to organic–heavy metal pollutants have not been fully reported. In this study, the adsorption performances (one of the key evaluation indicators of retardation barrier) of nine kinds of commonly used modified bentonites on multiple contaminants were comparatively investigated. The X–ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) analyses were also performed to unravel the adsorption mechanisms. Results show that the adsorption of modified bentonites on phenol and Pb(II) follows the order of SB–16 > PVA > CTAB > APAM > CTAB + PAC > PAC > CPAM > CTAB + PAC > CTAB + CPAM + APAM. Among all the samples, the bentonite modified with SB–16 showed the highest adsorption capacities for phenol and Pb(II). The surfactant molecules inserted in the interlayer space of montmorillonite increase the substrate spacing, which changes the structural properties of the bentonite from hydrophilic to hydrophobic and increases the adsorption of organic contaminants. On the other hand, the polymer has functional groups such as hydroxyl and carboxyl that can form a spatial three–dimensional cross–linking structure on the bentonite surface, providing more adsorption sites for heavy metal ions. These findings indicate the potential industrial applications of modified bentonite in a contaminant barrier system.

Abstract
Background

The purpose of this study was to clarify the clinical outcomes of surgical treatment for end-stage ankle osteoarthritis in patients aged ≥75 years and compare the outcomes with those of patients aged <75 years.
Methods

A total of 148 patients, including 65 post-total ankle arthroplasty and 83 post-ankle arthrodesis patients, were surveyed retrospectively. Clinical outcomes were assessed using the Japanese Society for Surgery of the Foot hindfoot scale and the self-administered foot evaluation questionnaire preoperatively and at the last follow-up. Patient characteristics, including age, sex, body mass index, radiographic severity, and follow-up period, were also assessed. Patients were divided into the older age group (≥75 years) and the younger age group (<75 years). Improvements in outcomes were then compared between the age groups using univariate analysis and analysis of covariance adjusted for patient characteristics. Post-total ankle arthroplasty and post-ankle arthrodesis were analyzed separately.
Results

All clinical outcome scores improved postoperatively in the older age group for both post-total ankle arthroplasty and post-ankle arthrodesis. For example, scores for pain and pain-related subscale of the self-administered foot evaluation questionnaire improved by 37 points (p < 0.001) for post-total ankle arthroplasty patients and by 35 points for post-ankle arthrodesis (p < 0.001). Furthermore, multivariate analysis showed that the improvements observed in all scores were not different between the older and younger age groups for both post-total ankle arthroplasty and post-ankle arthrodesis patients, except for the Self-Administered Foot Evaluation Questionnaire physical functioning subscale score for post-ankle arthrodesis patients.
Conclusions

Clinical outcomes improved significantly in post-total ankle arthroplasty and post-ankle arthrodesis patients aged ≥75 years. Moreover, the improvements were similar to those in patients aged <75 years. Therefore, surgical treatment of end-stage ankle osteoarthritis can be a viable treatment option, even in elderly patients.

Abstract
Development of biomimetic catalytic systems that can imitate or even surpass natural enzymes remains an ongoing challenge 1–3. This is particularly true in the context of accessing non-natural reactions by bioinspired approaches, which offer intriguing possibilities for benign and affordable chemical synthesis 4. Exploiting the untapped potential of inorganic solids by translating complex knowledge in (bio)molecular-based systems may constitute a potentially useful strategy for such purpose 5, but efforts to capitalize on the minimum catalytic unit of a versatile solid matrix have been largely unsuccessful. Here, we show how an all-inorganic biomimetic system bearing robust nitrogen-neighboured single cobalt site/pyridinic-N site (Co-N4/Py-N) pairs can act cooperatively as an oxidase mimic, which renders an engaged coupling of oxygen (O2) reduction with synthetically beneficial chemical transformations. By developing this broadly applicable platform, the scalable synthesis of greater than 100 industrially and pharmaceutically appealing O-silylated compounds via the unprecedented aerobic oxidation of hydrosilane under ambient conditions is demonstrated. Moreover, this heterogeneous oxidase mimic also offers potential for expanding the catalytic scope of enzymatic synthesis. We anticipate that the strategy demonstrated here will pave a new avenue for understanding the underlying nature of redox enzymes and open up a new class of material systems for artificial biomimetics.

Abstract
Aspergillus oryzae HML366 is a newly screened cellulase-producing strain. The endoglucanase HML ED1 from A. oryzae HML366 was quickly purified by two-step method ammonium sulfate precipitation and strong anion exchange column. SDS-PAGE electrophoresis indicated that the molecular weight of the enzyme was 68 kDa. The optimum temperature of the purified endoglucanase was 60 ℃ and the enzyme activity was stable below 70 ℃. The optimum pH was 6.5, and the enzyme activity was stable at pH between 4.5 to 9.0. The analysis indicated that additional Na+, K+, Ca2+, and Zn2+ reduced the catalytic ability of enzyme to the substrate, but Mn2+ enhanced its catalytic ability to the substrate.The Km and Vmax of the purified endoglucanase was 8.75 mg/mL and 60.24 μg/min·mL, respectively. Our study demonstrated that A. oryzae HML366 can produce a heat-resistant and wide pH tolerance endoglucanase HML ED1, which has potential industrial application value in bioethanol, paper, food, textile, detergent and pharmaceutical industries.

Published: January 2022

Abstract
Rotational motion lies at the heart of intermolecular, molecule-surface chemistry and cold molecule science, motivating the development of methods to excite and de-excite rotations. Existing schemes involve perturbing the molecules with photons or electrons which supply or remove energy comparable to the rotational level spacing. Here, we study the possibility of de-exciting the molecular rotation of a D2 molecule, from a J=2 to the non-rotating J=0 state, without using an energy-matched perturbation. We show that a magnetic field which splits the rotational projection states by only pico eV, can change the probability that a molecule-surface collision will stop a molecule from rotating and lose rotational energy which is 9 orders larger than that of the magnetic manipulation. Calculations confirm the origin of the control scheme, but also underestimate rotational flips (Δm_J≠0), highlighting the importance of the results as a sensitive benchmark for further developing theoretical models of molecule-surface interactions.
A Bi-level Decomposition Algorithm for Multi-factory Scheduling With Batch Delivery Problem
Authors: Marandi Fateme , Ghomi S.M.T. Fatemi 
Published: January 2022

Abstract
This paper introduces a multi-factory scheduling with batch delivery problem. A novel mixed-integer programming model is proposed to minimize the sum of total tardiness, holding and batching costs. A bi-level decomposition algorithm (BLDA) is developed involving two sub-problems: scheduling problem in the upper level and batching problem in the lower level. Four versions of the BLDA are created by combinations of CPLEX and simulated annealing in both levels, which interactively collaborate until the algorithm converges to a solution. The BLDAs are examined on several random and real-life test instances. A statistical analysis is performed by comparing the BLDAs’ solutions with the exact minimum and lower bound values of the total cost. The results indicate that about all versions of the developed BLDA provide high quality solutions for real-world zinc industry problems as well as generated instances in a reasonably short time. Finally, some managerial insights are derived based on sensitivity analysis.
