“We turn the lens … on ourselves:” assessing digital primary source library instruction through the lens of scholarship of teaching and learning
Authors: Keeran Peggy 
Published: November 2022

PurposeThe tenets of Scholarship of Teaching and Learning (SoTL) allow librarians to assess their teaching effectiveness through an evaluation of student learning. For the author, the sudden reliance on digital primary source collections during the 2020 pandemic lockdown provided a catalyst to examine her digital primary source instruction as a research project. In this case study, the author aims to examine library instruction for a required course for third-year history majors.Design/methodology/approachThe author collaborated with a history professor to identify “bottlenecks” related to digital primary source research, and to design two new library instruction sessions with in-class activities and assignments to address these bottlenecks. The professor and author then evaluated the assignments to determine if students had understood and incorporated the methods modeled during the research instruction classes.FindingsTeaching undergraduate history majors digital primary source research skills that will lead to the habits of mind of historians cannot be done in one academic quarter, for it takes time to develop disciplinary ways of thinking. Providing select core concepts more systematically earlier in the history major curriculum could make the enculturation into the discipline less fraught and confusing later, so that students begin learning foundational skills in their third year to carry them forward into their senior year when they write their theses.Originality/valueLittle has been written on digital primary source library instruction, which intersects with a variety of other research literacies. Assessing library instruction through the lens of SoTL is relatively new for academic librarians and has not been used in evaluating student learning in the digital primary source environment.
Tourism and regional carbon emissions: city-level evidence from China
Authors: Zhang Jiekuan , Zhang Yan 
Published: November 2022

Purpose
Although extensive studies have examined the link between tourism and carbon emissions, the impact of tourism on carbon emissions remains controversial. In contrast to prior studies, this study aims to investigate the effects of tourism on carbon emissions at the city level and the underlying moderating mechanism.

Design/methodology/approach
This study designs an econometric model drawing on panel data for 313 city-level regions in China from 2001 to 2019. This study also performs rigorous robustness tests to support the regression results. In addition, the temporal and spatial heterogeneity is analyzed based on which this study discusses the moderators of the effects of tourism on carbon emissions.

Findings
The results show that both tourist arrivals and tourism revenue significantly impact carbon emissions. Also, there exists a significant temporal and spatial heterogeneity of these effects. Economic development significantly enhances while green technology and tertiary industry development suppress the positive relationship between tourism and carbon emissions. Moreover, regarding the impact on carbon emissions, an explicit substitution exists between tourism and tertiary industry development.

Originality/value
For the first time, this study quantitatively estimates the moderators of tourism’s impact on carbon emissions and concludes the moderating effects of economic growth, technological progress and industrial structure, thus furthering the theoretical understanding of the heterogeneity of tourism’s association with carbon emissions. The study also fills a technical gap in previous studies by demonstrating the reliability of the findings through various robustness tests. This is also the first empirical study to systematically examine the relationship between tourism and carbon emissions in China.
Disentangling the causes of age‐assortative mating in bird populations with contrasting life‐history strategies

Published: November 2022

AbstractAge shapes fundamental processes related to behaviour, survival and reproduction, where age influences reproductive success, non‐random mating with respect to age can magnify or mitigate such effects. Consequently, the correlation in partners' age across a population may influence its productivity. Despite widespread evidence for age‐assortative mating, little is known about what drives this assortment and its variation. Specifically, the relative importance of active (same‐age mate preference) and passive processes (assortment as a consequence of other spatial or temporal effects) in driving age assortment is not well understood.In this paper, we compare breeding data from a great tit and mute swan population (51‐ and 31‐year datasets, respectively) to tease apart the contributions of pair retention, cohort age structure and active age‐related mate selection to age assortment in species with contrasting life histories.Both species show age‐assortative mating and variable assortment between years. However, we demonstrate that the drivers of age assortment differ between the species, as expected from their life histories and resultant demographic differences. In great tits, pair fidelity has a weak effect on age‐assortative mating through pair retention; variation in age assortment is primarily driven by fluctuations in age structure from variable juvenile recruitment. Age‐assortative mating is, therefore, largely passive, with no evidence consistent with active age‐related mate selection. In mute swans, age assortment is partly explained by pair retention, but not population age structure, and evidence exists for active age‐assortative pairing.This difference is likely to result from shorter life‐spans in great tits compared with mute swans, leading to fundamental differences in their population age structure, whereby a larger proportion of great tit populations consist of a single age cohort. In mute swans, age‐assortative pairing through mate selection may also be driven by greater age‐dependent variation in fitness.The study highlights the importance of considering how different life histories and demographic differences arising from these affect population processes that appear congruent across species. We suggest that future research should focus on uncovering the proximate mechanisms that lead to variation in active age‐assortative mate selection (as seen in mute swans); and the consequences of variation in age structure on the ecological and social functioning of wild populations.
Understanding the De‐internationalization of Entrepreneurial SMEs in a Volatile Context: A Reconnoitre on the Unique Compositions of Internal and External Factors

Published: November 2022

AbstractIn recent years, the global business environment has witnessed a wave of de‐internationalization not only among multinationals but also among small‐ and medium‐sized enterprises (SMEs). This disengagement of cross‐border activities is deemed to be driven by various firm‐specific factors, as well as by external factors. Building on the premise of the non‐linear internationalization debate and focusing on the dynamic capabilities view and institutional theory, this paper aims to disentangle the extent to which internal factors (IFs) and external factors (EFs) drive SMEs towards de‐internationalization. To do this, we take advantage of a hybrid multilayer decision‐making mathematical modelling approach to explore SME de‐internationalization at two levels. Our findings at the exhaustive level contribute to the de‐internationalization literature by proposing distinct frameworks that highlight the interrelationship amongst IFs and EFs. And our results at the subordinate level constitute the identification of four unique compositions leading to different de‐internationalization modes. In this vein, we define two categories of factors, namely reducing and terminating factors, which drive SMEs into respectively partial and full de‐internationalization.
Political challengers and norm erosion in advanced democracies
Authors: HINTERLEITNER MARKUS , SAGER FRITZ 
Published: November 2022

AbstractHow do politicians in advanced democracies get away with violating political norms? Although norm violators confront a powerful establishment that can penalize them, norm violations currently occur in many advanced democracies. This article analyzes the conflicts between norm‐violating challengers and established politicians and parties as norm defenders in multiparty systems to contribute to the discipline's understanding of norm erosion processes. Based on diachronic and synchronic comparisons of conflicts over norm violations in Austria and Germany, the article reveals how political challengers can already damage democratic norms from a position of institutional weakness. Norm violators that make ambiguous provocations and can leverage their previously acquired democratic credentials, can more credibly dispel attempts to stigmatize them as undemocratic. In doing so, they turn the tables on the political establishment and portray its sanctions as a form of ‘excessive retaliation’ that constitutes a norm violation in itself. The article concludes with the unsettling finding that (verbal) norm protection can facilitate norm erosion.
Utilization of salt‐rich by‐products from the dairy industry as feedstock for recombinant protein production by Debaryomyces hansenii

Published: November 2022

AbstractThe dairy industry processes vast amounts of milk and generates high amounts of secondary by‐products, which are still rich in nutrients (high Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD) levels) but contain high concentrations of salt. The current European legislation only allows disposing of these effluents directly into the waterways with previous treatment, which is laborious and expensive. Therefore, as much as possible, these by‐products are reutilized as animal feed material and, if not applicable, used as fertilizers adding phosphorus, potassium, nitrogen, and other nutrients to the soil. Finding biological alternatives to revalue dairy by‐products is of crucial interest in order to improve the utilization of dry dairy matter and reduce the environmental impact of every litre of milk produced. Debaryomyces hansenii is a halotolerant non‐conventional yeast with high potential for this purpose. It presents some beneficial traits – capacity to metabolize a variety of sugars, tolerance to high osmotic environments, resistance to extreme temperatures and pHs – that make this yeast a well‐suited option to grow using complex feedstock, such as industrial waste, instead of the traditional commercial media. In this work, we study for the first time D. hansenii's ability to grow and produce a recombinant protein (YFP) from dairy saline whey by‐products. Cultivations at different scales (1.5, 100 and 500 ml) were performed without neither sterilizing the medium nor using pure water. Our results conclude that D. hansenii is able to perform well and produce YFP in the aforementioned salty substrate. Interestingly, it is able to outcompete other microorganisms present in the waste without altering its cell performance or protein production capacity.

AbstractBackgroundMyasthenia gravis (MG) patients are reported to have a high risk of other autoimmune diseases (ADs), and thymectomy may increase the risk further. A cohort of MG patients in which thymectomy was performed were investigated to analyze the prevalence, types and features of the new onset ADs.MethodsConsecutive patients with MG who underwent thymectomy at Beijing Hospital between January 2012 and August 2021 were retrospectively enrolled. Patients with a postoperative follow‐up period shorter than a year or incomplete clinical records were excluded. Clinical and follow‐up data were collected. Statistical analyses were performed using SPSS version 22.0.ResultsA total of 445 patients were included in this study. The median follow‐up period was 72 months (range, 12–135 months). A total of 63 (14.2%) MG patients had concurrent ADs. The incidence rate was higher than the background prevalence of population (5%), and also higher than that of a former Chinese MG cohort (11.6%). A total of 47 patients (10.6%) were diagnosed with ADs before thymectomy, and 19 (4.3%) developed a new AD after thymectomy. The most common types of new onset ADs after thymectomy were Hashimoto's thyroiditis and rheumatoid arthritis (RA), which were different from those before thymectomy (hyperthyroidism and Hashimoto's thyroiditis). The incidence rate of new onset RA (1.35%) was higher than the frequency of RA before thymectomy (0.45%), and also higher than the incidence rate in a Chinese MG cohort (0.5%). There was a higher proportion of female patients (p = 0.026) with postoperative ADs. A younger age at operation may increase the risk of nonthymoma MG patients (p = 0.040) developing ADs. The postoperative treatment effect of MG was similar between patients with and without new onset ADs (p > 0.05).ConclusionsWe observed a higher incidence rate of autoimmune diseases, especially rheumatoid arthritis, in MG patients after thymectomy. The most common types of ADs after thymectomy were different from those before thymectomy. New onset ADs tended to occur in female and young nonthymoma MG patients. The postoperative effect of MG was not related with the new occurrence of ADs.
Extreme weather events and high Colombian food prices: A non‐stationary extreme value approach1

Published: November 2022

AbstractGiven the importance of climate change and the increase of its severity under extreme weather events, we analyze the main drivers of high food prices in Colombia between 1985 and 2020 focusing on extreme weather shocks like a strong El Niño. We estimate a non‐stationary extreme value model for Colombian food prices. Our findings suggest that perishable foods are more exposed to extreme weather conditions in comparison to processed foods. In fact, an extremely low precipitation level explains only high prices in perishable foods. The risk of high perishable food prices is significantly larger for low rainfall levels (dry seasons) compared to high precipitation levels (rainy seasons). This risk gradually results in higher perishable food prices. It is nonlinear and is also significantly larger than the risk related to changes in the US dollar‐Colombian peso exchange rate and fuel prices. Those covariates also explain high prices for both perishable and processed foods. Finally, we find that the events associated with the strongest El Niño in 1988 and 2016 are expected to reoccur once every 50 years.

AbstractThere has been an important change in the clinical characteristics and immune profile of Coronavirus disease 2019 (COVID‐19) patients during the pandemic thanks to the extensive vaccination programs. Here, we highlight recent studies on COVID‐19, from the clinical and immunological characteristics to the protective and risk factors for severity and mortality of COVID‐19. The efficacy of the COVID‐19 vaccines and potential allergic reactions after administration are also discussed. The occurrence of new variants of concerns such as Omicron BA.2, BA.4, and BA.5 and the global administration of COVID‐19 vaccines have changed the clinical scenario of COVID‐19. Multisystem inflammatory syndrome in children (MIS‐C) may cause severe and heterogeneous disease but with a lower mortality rate. Perturbations in immunity of T cells, B cells, and mast cells, as well as autoantibodies and metabolic reprogramming may contribute to the long‐term symptoms of COVID‐19. There is conflicting evidence about whether atopic diseases, such as allergic asthma and rhinitis, are associated with a lower susceptibility and better outcomes of COVID‐19. At the beginning of pandemic, the European Academy of Allergy and Clinical Immunology (EAACI) developed guidelines that provided timely information for the management of allergic diseases and preventive measures to reduce transmission in the allergic clinics. The global distribution of COVID‐19 vaccines and emerging severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) variants with reduced pathogenic potential dramatically decreased the morbidity, severity, and mortality of COVID‐19. Nevertheless, breakthrough infection remains a challenge for disease control. Hypersensitivity reactions (HSR) to COVID‐19 vaccines are low compared to other vaccines, and these were addressed in EAACI statements that provided indications for the management of allergic reactions, including anaphylaxis to COVID‐19 vaccines. We have gained a depth knowledge and experience in the over 2 years since the start of the pandemic, and yet a full eradication of SARS‐CoV‐2 is not on the horizon. Novel strategies are warranted to prevent severe disease in high‐risk groups, the development of MIS‐C and long COVID‐19.

AbstractBackgroundPremature ejaculation (PE) is the most common ejaculatory function disorder. To date, four types of PE have been identified depending on the severity, onset, and course of the problem.ObjectivesThe aim of this study was to investigate whether or not there is a difference between these types in respect of anxiety, perceived stress, insomnia severity, and sleep chronotype.Materials and methodsThe study included 112 patients diagnosed with PE in our clinic between October 2021 and May 2022. The patients were separated into groups according to PE types of lifelong (LPE, n = 39), acquired (APE, n = 45), variable (VPE, n = 10), and subjective (SPE, n = 18). In addition to the demographic and clinical data, the scores were recorded of all participants in the International Index of Erectile Function‐5, Hospital Anxiety and Depression Scale, Premature Ejaculation Diagnostic Tool (PEDT), Insomnia Severity Index (ISI), Perceived Stress Scale (PSS), and Morningness Eveningness Questionnaire (MEQ).ResultsSPE was determined more in university graduate patients (42.1% vs. LPE, 21.1%; APE, 36.8%; VPE, 0%; p = 0.01). In patients with APE, erectile dysfunction was more severe (80.0% vs. LPE, 8.0%; SPE, 12.0%; VPE, 0%; p < 0.001). The median (IQR) PEDT score was determined to be higher in APE than in LPE and SPE (16(5), 13(7), 11(5), p = 0.001, respectively). Patients with APE were determined to have higher median (IQR) ISI (21(9) vs. LPE, 8(7); SPE, 5(8); VPE 8(4), p < 0.001) and PSS scores (35(12) vs. LPE, 22 (7); SPE,22(5); VPE 21(6), p < 0.001), the sleep chronotype was more eveningness according to the MEQ (80.8% vs. LPE, 19.2%; VPE, 0%; SPE, 0%; p < 0.001), and there were seen be more anxiety symptoms (75.5% vs. LPE,12.2%; VPE, 0%; SPE, 12.2%; p < 0.001).ConclusionPsychological status and sleep health were concluded to be important factors for PE patients, and the patients with acquired PE were the group most affected by these factors.

AbstractPurposeThe Senhance digital laparoscopy system (SDLS) is a novel platform developed for digitization in endoscopic surgery. This retrospective study aimed to evaluate the short‐term outcome in the initial 30 consecutive patients.MethodsSDLS cholecystectomies were performed in 30 consecutive patients (13 male, 17 female) by a single surgeon from September 2020 to March 2022. The patients' median age (range) was 77.5 (27–82) years, and median body mass index was 23.3 (19–38) kg/m2. Four trocars were used, three of which were docked to manipulator arms of the SDLS. Surgical procedures performed with the SDLS were almost the same as those by conventional surgery.ResultsMedian docking time, cockpit time, and operation time in minutes were 4 (3–13), 34 (13–81), and 69 (47–201), respectively. Operation time after the sixth case tended to shorten compared with that for the initial five cases. Three cases (10%) were converted to conventional laparoscopic surgery due to severe cholecystitis, but none required conversion to open surgery. Postoperative complications of Clavien–Dindo grade ≥II were not observed.ConclusionThis retrospective study showed that cholecystectomy using the SDLS appeared to be safe and feasible in limited cases without severe inflammation.

Published: November 2022

AbstractBackgroundPeri‐implantitis constitutes one of the most frequent late dental implant complications. The disease is initiated by bacterial infection; therefore, anti‐infective peri‐implantitis treatment strategies are required to arrest the progressive marginal bone loss and maintain the affected implant in function. Although nonsurgical treatment strategies appear to be of limited predictability, treatment outcomes have been frequently improved following surgical interventions.PurposeThe present narrative review describes various surgical peri‐implantitis treatment modalities, with respect to their indications, performance, and effectiveness.Materials and MethodsThe present narrative review considered the most relevant studies in the field published in the English language.ResultsSurgical peri‐implantitis treatment approaches can be categorized as nonreconstrucive therapy, reconstructive therapy, and combined therapy (ie, reconstructive and resective therapy). In addition to disease resolution, reconstructive approaches also seek to regenerate the bone defect and achieve reosseointegration.ConclusionsThe severity of the disease, the regenerative potential of the defetc and esthetic demands of the patient are the factors determining the surgical peri‐implantitis treatment modality.
