Exceptionalism and Evasion: How Scholars Reason About Air Travel
Authors: Eriksson Elina , Söderberg Maria Wolrath , Wormbs Nina 
Published: January 2022

AbstractUnderstanding how scholars reason about their own flying habits is important when dealing with the problems of large emissions from academic air travel. This study is based on a travel habits survey with scholars at KTH Royal Institute of Technology in Stockholm. KTH has relatively high emissions from air travel, but at the same time, it has a high profile in matters of sustainability and a lot of research related to this theme. One can therefore assume a high degree of knowledge about the climate crisis and the climate impact of various actions. It is also plausible that KTH scholars meet special expectations to be role models and that practices in conflict with their teaching can have consequences for the public confidence in the university. In this study, we look at how scholars reason about how emissions from their flying could be reduced. Their responses display a spectrum of varying attitudes, from climate scepticism to a commitment to radical transformation, with the majority in between, either suggesting different types of concrete changes or invoking arguments to justify the status quo. The proposed interventions, several of which are ingenious and wise, can guide university managements to strategies that have support from employees. The more reluctant arguments point to cultural and discursive habits that must be understood and met in an empathetic way.
Academic Aeromobility in the Global Periphery
Authors: Higham James , Hopkins Debbie , Orchiston Caroline 
Published: January 2022

AbstractAcademics are part of a small minority that are responsible for disproportionate air travel emissions. Responding to high aviation emissions requires that the complexities of academic air travel practices are understood in specific geographical and institutional contexts. This chapter addresses the work-sociology of academic aeromobility in the context of the global periphery. We report on a programme of interviews conducted prior to COVID-19 with academics at the University of Otago (Aotearoa/New Zealand), where the aeromobility practices of academics are uniquely shaped by extreme geographical distance. Our empirical contribution is presented in the four themes that emerged from our analysis: complex drivers; selective substitution; ‘Don’t weaken me!’ and assorted scalar accountabilities. We then discuss aspects of resistance to change but also avenues of opportunity to reimagine academic air travel practices, which have been accelerated by the COVID-19 pandemic. We specifically address the emergence of a post-COVID ‘new normal’ and conclude with the urgent need for collective action that is coordinated among individual academics, institutions, disciplinary associations and conference organisers. Entrenching the ‘new normal’ will be critical to resolving the unsustainable aeromobilities of academics and institutions that are globally distant.
The Virus and the Elephant in the Room: Knowledge, Emotions and a Pandemic—Drivers to Reducing Flying in Academia
Authors: Jacobson Lisa 
Published: January 2022

AbstractThis chapter explores individual incentives and barriers to reducing air travel, with the focus on people who have taken a decision to reduce flying due to climate change. During the COVID-19 pandemic in 2020, six semi-structured interviews were performed with academics—three who had already cut down on flying and three who were grounded due to the pandemic. They were compared with a set of interviews with 26 Swedish citizens, performed in 2017–2018, which had shown that internalised knowledge of climate change was an important driver to change behaviour. Awareness led to negative emotions and a personal tipping point where a decision to reduce flying was made. However, among these interviewees, even people with a strong drive to reduce flying felt trapped in practices, norms and infrastructures. The academics reported similar incentives and barriers as the broader group but also specific challenges for them as researchers. Surprisingly, the pandemic was perceived as a testbed for new travel habits, and not as a big obstacle for their scientific work. None believed that they would return to an equally aeromobile lifestyle, and two of them described it as a chance to reconcile habits with their pro-environmental values.

AbstractLivestock sector is the backbone of Indian agriculture and plays a crucial role in the development of the rural economy. More than one-fifth (23%) of agricultural households with area less than 0.01 hectare reported livestock as their principal source of income (GoI Government of India (2014) Key indicators of situation of agricultural). Livestock is one of the fastest-growing sectors of Indian agriculture. While the share of overall agriculture and allied sectors in Gross Value Added (GVA) declined from 18.2% in 2014–15 to 17.8% in 2019–20, the share of livestock sector in GVA increased from 4.4% to 5.1% in the same period (GoI Government of India (2021) The economic survey (2020–21). Ministry of Finance. Government of India). Livestock sector accounts for 31% of the gross value of output in agriculture and allied sector (GVOA). Within livestock, milk is the biggest component with 20% share in GVOA. In fact, milk is the largest agriculture commodity in terms of value of output worth INR 772,705 crores in 2018–19 which was more than the value of cereals, pulses, oilseeds and sugarcane combined worth INR 623,462 crores (MoSPI. (2021). National Accounts Statistics 2020. Central Statistical Organization. Ministry of Statistics and Program Implementation.). Around 70 million of rural households are engaged in milk production, most of them are landless, marginal, and small farmers (NCAER. (2020). Analyzing Socio-Economic Impact of National Dairy Plan—I. National Council for Applied Economic Research. February 2020.). As a source of livelihood for million of poor households, dairying also supplements their dietary sources of protein and nutrition thus playing a critical role in the country’s food security needs.

AbstractIn the livestock sector in India, poultry farming holds a prominent position owing to its impressive growth led by the private sector. Poultry sector has shown rapid growth, with chicken meat growing at an average annual growth rate of 9% and eggs growing at 6% from 2000–01 to 2018–19 (DAHD DAHD (2020) Basic animal husbandry statistics 2020. Department of Animal Husbandry, Dairying and Fisheries. Ministry of Agriculture & Farmers Welfare. Government of India). The recent steady growth in domestic demand for chicken meat has made it possible to increase production with a ready market putting India among the top poultry producers in the world. India was the third-largest egg producer after China and the USA with a production of 88 billion eggs and fifth-largest chicken meat producer with a production of 3.5 million tonnes during 2017–18 (FAOSTAT (2018) Food and Agriculture data. Retrieved from Food and Agriculture Organization of the United Nations: http://www.fao.org/faostat/en/#data). This transformation in the poultry sector was led by the commercial poultry industry which contributes about 80% of the total poultry production. The other 20% is produced by the traditional backyard poultry. The broiler industry is concentrated in the southern and western states and accounts for a major share of total output. Similarly, the layer industry is dominated by well-developed states like Andhra Pradesh, Tamil Nadu and Maharashtra, accounting for nearly 60% of the production (DAHDF (2017) National Action Plan for Egg & Poultry-2022 for Doubling Farmers’ Income by 2022. Department of Animal Husbandry, Dairying & Fisheries Ministry of Agriculture & Farmers Welfare Government of India.). Commercial poultry farming is yet to make a dent in more populous states like Bihar, Orissa and Uttar Pradesh.

Published: January 2022

AbstractKey messageIncluding additive and additive-by-additive epistasis in a NOIA parametrization did not yield orthogonal partitioning of genetic variances, nevertheless, it improved predictive ability in a leave-one-out cross-validation for wheat grain yield.AbstractAdditive-by-additive epistasis is the principal non-additive genetic effect in inbred wheat lines and is potentially useful for developing cultivars based on total genetic merit; nevertheless, its practical benefits have been highly debated. In this article, we aimed to (i) evaluate the performance of models including additive and additive-by-additive epistatic effects for variance components (VC) estimation of grain yield in a wheat-breeding population, and (ii) to investigate whether including additive-by-additive epistasis in genomic prediction enhance wheat grain yield predictive ability (PA). In total, 2060 sixth-generation (F6) lines from Nordic Seed A/S breeding company were phenotyped in 21 year-location combinations in Denmark, and genotyped using a 15 K-Illumina-BeadChip. Three models were used to estimate VC and heritability at plot level: (i) “I-model” (baseline), (ii) “I + GA-model”, extending I-model with an additive genomic effect, and (iii) “I + GA + GAA-model”, extending I + GA-model with an additive-by-additive genomic effects. The I + GA-model and I + GA + GAA-model were based on the Natural and Orthogonal Interactions Approach (NOIA) parametrization. The I + GA + GAA-model failed to achieve orthogonal partition of genetic variances, as revealed by a change in estimated additive variance of I + GA-model when epistasis was included in the I + GA + GAA-model. The PA was studied using leave-one-line-out and leave-one-breeding-cycle-out cross-validations. The I + GA + GAA-model increased PA significantly (16.5%) compared to the I + GA-model in leave-one-line-out cross-validation. However, the improvement due to including epistasis was not observed in leave-one-breeding-cycle-out cross-validation. We conclude that epistatic models can be useful to enhance predictions of total genetic merit. However, even though we used the NOIA parameterization, the variance partition into orthogonal genetic effects was not possible.
What is the “safe zone” for transition of coronal alignment from systematic to a more personalised one in total knee arthroplasty? A systematic review
Authors: Schelker Benjamin L. , Nowakowski Andrej M. , Hirschmann Michael T. 
Published: January 2022

Abstract
Purpose
In total knee arthroplasty (TKA), implants are increasingly aligned based on emerging patient-specific alignment strategies, such as unrestricted kinematic alignment (KA), according to their constitutional limb alignment (phenotype alignment), which results in a large proportion of patients having a hip-knee angle (HKA) outside the safe range of ± 3° to 180° traditionally considered in the mechanical alignment strategy. The aim of this systematic review is to investigate whether alignment outside the safe zone of ± 3° is associated with a higher revision rate and worse clinical outcome than alignment within this range.

Methods
A systematic literature search was conducted in PubMed, Embase, Cochrane and World of Science, with search terms including synonyms and plurals for “total knee arthroplasty”, “alignment”, “outlier”, “malalignment”, “implant survival” and “outcome”. Five studies were identified with a total number of 927 patients and 952 implants. The Oxford Knee Score (OKS) and the WOMAC were used to evaluate the clinical outcome. The follow-up period was between 6 months and 10 years.

Results
According to HKA 533 knees were aligned within ± 3°, 47 (8.8%) were varus outliers and 121 (22.7%) were valgus outliers. No significant differences in clinical outcomes were found between implants positioned within ± 3° and varus and valgus outliers. Likewise, no significant differences were found regarding revision rates and implant survival.

Conclusion
The universal use of the “safe zone” of ± 3° derived from the mechanical alignment strategy is hardly applicable to modern personalised alignment strategies in the light of current literature. However, given the conflicting evidence in the literature on the risks of higher revision rates and poorer clinical outcomes especially with greater tibial component deviation, the lack of data on the outcomes of more extreme alignments, and regarding the use of implants for KA TKA that are actually designed for mechanical alignment, there is an urgent need for research to define eventual evidence-based thresholds for new patient-specific alignment strategies, not only for HKA but also for FMA and TMA, also taking into account the preoperative phenotype and implant design. It is of utmost clinical relevance for the application of modern alignment strategies to know which native phenotypes may be reproduced with a TKA.

Published: January 2022

AbstractDouble-walled metal pipes are important components for heat exchange and liquid transportation. They can be manufactured by mechanical drawing of two concentric pipes. In this work, a mechanical model is developed to analyze the stress state evolution during the manufacturing process, and the criterion for forming the double-walled pipe was given under the ideal elastoplastic and thick-walled assumptions. The model also encompasses the results deduced under the thin-walled assumption. Numerical simulations confirmed that the accuracy of the analytical model was within 5%. The application on actual steel materials with various parameters varied, including the wall thickness and initial gap, was analyzed. This work can provide theoretical support to industrial manufacturing procedures and help to reduce costs by eliminating required test procedures.
Multiple perspectives integration for virtual reality-aided assemblability assessment in narrow assembly spaces

Published: January 2022

AbstractVirtual reality (VR) has been proved as a promising tool for industrial design, but the traditional VR interface of first-person perspective (1PP) is not efficient to support assemblability assessment in narrow assembly spaces. In this paper, we proposed the multi-perspectives interface (MPI) which integrates the 1PP and the third-person perspective (3PP) using the handheld world-in-miniature (WIM). The MPI allows users to simulate the assembly operations in a natural manner similar to 1PP, while providing users with an overview of the assembly status through the WIM to assess the assemblability with superior spatial awareness. Two studies were conducted to test the performance of the proposed MPI. The first study tested user’s interaction performance in MPI using a common interaction task, which reveals stronger spatial awareness in MPI than in 1PP without the cost of losing natural interaction. Based on the results of the first study, the second study tested the performance, usability, and workload of MPI in an assemblability assessment task. The results show the advantages of MPI in the reachability evaluation in the narrow spaces. The main contribution of this paper is improving the interface and user-interface interaction in VR-aided assembly assessment system to improve user’s interaction performance and assessment ability in narrow assembly spaces.
The polymorphisms of extracellular matrix-remodeling genes are associated with pelvic organ prolapse
Authors: Li Lei , Ma Yidi , Yang Hua , Sun Zhijing , Chen Juan , Zhu Lan 
Published: January 2022

Abstract
Introduction and hypothesis
Extracellular matrix (ECM) synthesis and metabolism abnormalities may influence the pelvic supporting system and lead to the occurrence and development of pelvic organ prolapse (POP). Genetic polymorphisms of such related genes have been increasingly studied. This study aims to explore the association between the single-nucleotide polymorphisms (SNPs) of genes encoding ECM processing enzymes (a disintegrin and metalloproteinase with thrombospondin motifs [ADAMTSs]), ECM degrading enzymes (matrix metalloproteinases [MMPs]) and their tissue inhibitors of metalloproteinase (TIMPs), and POP.

Methods
We conducted an association study including 48 women with POP at stages III and IV and 48 women without prolapse in Chinese groups. SNPs were identified using the target region sequencing technique. We performed Fisher’s exact tests to assess the association between SNPs and POP in the unadjusted model and logistic regression analysis in the adjusted model, adjusting for delivery and pregnancy.

Results
There was a significant association between TIMP2 SNP rs2277698 (odds ratio [OR], 0.37; 95% confidence interval [CI], 0.16–0.82; P = 0.015), ADAMTS13 SNP rs149586801 (OR, 0.18; 95% CI, 0.05–0.69; P = 0.012), and ADAMTS1 SNPs rs370850 and rs422803 (OR, 3.71; 95% CI, 1.35–10.15; P = 0.011 for both), rs402007, rs428785, rs434857, and rs445784 (OR, 2.18; 95% CI, 1.05–4.56; P = 0.038 for the four), and POP in the adjusted model.

Conclusion
TIMP2, ADAMTS13, and ADAMTS1 might be candidate genes for POP. Our results provide preliminarily new evidence for future investigation of these genes in the pathophysiology of POP.

Published: January 2022

Abstract
Introduction and hypothesis
The aim of this prospective study was to examine the impact of sociodemographic, pregnancy and obstetric characteristics on sexual function 12 months postpartum in primiparous women. We hypothesized that sexual function would decrease after childbirth.

Methods
Between 1 October 2014 and 1 October 2017, all nulliparous women in early pregnancy registering for maternity health care in Region Örebro County, Sweden, were invited to participate in this prospective study. A total of 958 women were included. Sexual activity and function were measured at early pregnancy, 8 weeks postpartum and 12 months postpartum using the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12). The associations between sociodemographic, pregnancy and obstetric characteristics and sexual activity and function from early pregnancy to 12 months postpartum were examined using linear and logistic models based on generalized estimating equations.

Results
We found that the prevalence of sexually active women decreased from 98.0% in early pregnancy to 66.7% at 8 weeks postpartum, but increased to 90.0% at 12 months postpartum. Age ≥ 35 years, second-degree perineal tear and current breastfeeding were statistically significant risk factors for sexual inactivity at 12 months postpartum. Poor self-reported health in early pregnancy was statistically significantly associated with decreased sexual function at 12 months postpartum.

Conclusions
A majority of women resumed sexual activity at 8 weeks postpartum and most women at 12 months postpartum; the decrease in sexual function at 12 months postpartum was small and few risk factors were observed.
Perspectives of future lung toxicology studies using human pluripotent stem cells
Authors: Masui Atsushi , Hirai Toyohiro , Gotoh Shimpei 
Published: January 2022

AbstractThe absence of in vitro platforms for human pulmonary toxicology studies is becoming an increasingly serious concern. The respiratory system has a dynamic mechanical structure that extends from the airways to the alveolar region. In addition, the epithelial, endothelial, stromal, and immune cells are highly organized in each region and interact with each other to function synergistically. These cells of varied lineage, particularly epithelial cells, have been difficult to use for long-term culture in vitro, thus limiting the development of useful experimental tools. This limitation has set a large distance between the bench and the bedside for analyzing the pathogenic mechanisms, the efficacy of candidate therapeutic agents, and the toxicity of compounds. Several researchers have proposed solutions to these problems by reporting on methods for generating human lung epithelial cells derived from pluripotent stem cells (PSCs). Moreover, the use of organoid culture, organ-on-a-chip, and material-based techniques have enabled the maintenance of functional PSC-derived lung epithelial cells as well as primary cells. The aforementioned technological advances have facilitated the in vitro recapitulation of genetic lung diseases and the detection of ameliorating or worsening effects of genetic and chemical interventions, thus indicating the future possibility of more sophisticated preclinical compound assessments in vitro. In this review, we will update the recent advances in lung cell culture methods, principally focusing on human PSC-derived lung epithelial organoid culture systems with the hope of their future application in toxicology studies.
