Doing or calculating lean? A sensemaking perspective on workplace learning
Authors: Hermanrud Inge , Haukåsen Ole Andreas 
Published: January 2023

Purpose
The purpose of this paper is to present and discuss two different learning approaches to lean through a sensemaking lens.

Design/methodology/approach
This is comparative case study within one organisation, and a qualitative analysis of interview data, participative observations and documents.

Findings
Although this study found that both practices promoted lean thinking in the organisation, the “calculating lean approach” has an approach oriented towards one profession, namely, medical doctors, whereas “doing lean” has a more multi-professional-oriented approach.

Originality/value
This research enriches the literature on workplace learning in relation to lean, seen from a practice-based perspective. The authors argue that “The calculating lean approach” and its use of data presentations is best suited to persuade the powerful doctors to join, when working with small improvements. “The doing lean approach,” on the contrary, is more suited to promote more comprehensive changes from the bottom up that require a deeper understanding of lean among all the professions involved.

Authors: Zhao Xiaoyang , Mao Xia , Lu Yuxiu 
Published: January 2023

PurposeThis study aims to investigate the factors affecting urban economic development in emerging economic market countries and to provide a new research perspective on urban skyscraper construction.Design/methodology/approachAn empirical analysis based on a difference-in-differences (DID) model is conducted using data of urban data in China that expand into developed markets from 2003 to 2018.FindingsThe results of the spatial heterogeneity test indicate that the construction of skyscrapers has a significant promotional effect on the eastern city's economy. In contrast, it has a significant inhibitory effect in the central and western regions. Further findings demonstrate that the construction of skyscrapers can influence urban economic development by promoting industrial agglomeration, especially when the transmission effect of the diversified accumulation of tertiary industry is more prominent. The expansion analysis shows that skyscrapers have increased the level of trade in the city, and the impact on trade has an optimal height.Research limitations/implicationsThis paper focuses on the economic and trade effects of skyscrapers, and the optimal height of skyscrapers needs to be discussed in more depth, which is also the next problem the researchers need to study.Practical implicationsThe government should attach importance to and promote the construction of urban skyscrapers, and do a good job in overall planning and design. The city should formulate preferential policies in land, taxation, finance, system and other aspects to increase support for urban skyscraper construction and promote local economic development.Originality/valueThis study focuses on the impact of urban skyscraper construction on the economic and trade development of cities in developing countries, which not only complements the relevant research on the economic effects of urban skyscraper construction, but also helps to provide reference for the sustainable development of urbanization in many developing countries.

Authors: Dutta Sudev , Bansal Payal 
Published: January 2023

Purpose
The purpose of this review paper is to outline the parachute materials and its behavior. To enhance parachute life, it is highly desirable to consider the commercial angle for any parachute manufacturing industry and its components under varying operational conditions. Hence, the knowledge of various textile materials and operational conditions which contributes the parachute strength and durability will be helpful for industries/researchers.

Design/methodology/approach
This section is not applicable for a review paper.

Findings
Parachute is a material used in numerous real-time applications such as man-drop, cargo delivery, aircraft recovery and aircraft decelerator which drastically reduces human efforts and time. However, each application requires a unique design and fabric selection to achieve the area of drag needed and the terminal velocity of the parachute material while in flight. For designing a man-drop parachute, the most critical parameters are weight and strength which must be considered during manufacturing. The army person uses the man-drop parachute, which must be as light as possible.

Originality/value
This paper is an original review work and will be helpful for parachute manufacturers/researchers to enhance the life of parachutes with improved functionality.
Cumulative propagule pressure exerted by escaped pet parrots

Published: January 2023

AbstractThe global pet trade provides a pathway for introduced species to invade new environments. Most studies use trade data as an indirect proxy for propagule pressure exerted by the pet trade. Instead, we quantify the reported rate of loss of captive birds, assess factors that might influence this rate, simulate the survival and retrieval of birds and the overall cumulative propagule pressure exerted by pet birds on the environment.We used online listings of lost birds to estimate the propagule pressure that the pet trade exerts on the establishment of introduced bird species in Aotearoa–New Zealand. Listings from two popular websites were monitored daily for over 3.5 years, and information was recorded on the frequency, location, species composition and characteristics of the loss events. We investigated a range of factors that may influence the rate of loss events, such as season and human population size. We also developed a simulation approach to investigate the cumulative propagule pressure in Auckland, New Zealand's largest city.A total of 1205 birds and at least 33 species were reported lost nationwide during our monitoring period, 92% of which were parrots. We found that the reported loss rate was higher in areas of higher human population size and median income, and lower in the winter months.Simulation results predict that in any given month in Auckland there is an average of at least 491 escaped birds, including 136 potential breeding pairs, and for seven species the chance that at least one locality has a male/female pair at large exceeds 80%.Synthesis and applications. Online listings of lost pets provide an excellent source of data from which to identify species with high propagule pressure in specific localities. We identified escaped parrot species as a high‐risk invasion pathway, as they contribute to a high and consistent propagule pressure. A preventative approach, by banning the sale of these species, is the most appropriate pest management strategy for reducing the probability of establishment and potential impact.
THE LIMITS OF INFRASTRUCTURE: Public Transport in a Post‐colonial City
Authors: Peters Robbie 
Published: January 2023

AbstractSince the 1940s, the people of the neighbourhoods (kampungs) around Surabaya's derelict Ngagel industrial estate have made a living by repurposing the remains of what was once one of Asia's most modern road, rail and industry networks. The remains—in the form of leftover fuel, labour and factory parts—are used to rebuild and repair improvised transport vehicles like bicycle‐taxis (becak), minibuses (bemo) and motorbike‐taxis (ojek). The repurposing happens at the limits of a capital‐intensive heavy infrastructure of factories, trams and buses. The limits are those points where such infrastructure fails and a household‐funded mosquito‐fleet of light vehicles succeeds. Repurposing gives those who do it a right to infrastructure by providing the city with much‐needed public transport. In Surabaya, public transport begins at its limits through the improvisations of people who live in the productive remains of capital‐intensive heavy infrastructure. These people live in Surabaya's deindustrialized urban core, where life is made in the ruins of infrastructure through the breaking‐down of it, the reworking of it, the right to it, and the leakage of it—the means through which rank‐and‐file people rather than states and corporations forge infrastructure.

Published: January 2023

AbstractBackgroundThere is conflicting evidence regarding the safety of Kielland's rotational forceps delivery (KRFD) in comparison with other modes of delivery for the management of persistent fetal malposition in the second stage of labour.ObjectivesTo derive estimates of risks of maternal and neonatal complications following KRFD, compared with rotational ventouse delivery (RVD), non‐rotational forceps delivery (NRFD) or a second‐stage caesarean section (CS), from a systematic review and meta‐analysis of the literature.Search StrategyStandard search methodology, as recommended by the Cochrane Handbook for Systematic Reviews of Interventions.Selection CriteriaCase series, prospective or retrospective cohort studies and population‐based studies.Data Collection and AnalysisA meta‐analysis using a random‐effects model was used to derive weighted pooled estimates of maternal and neonatal complications.Main ResultsThirteen studies were included. For postpartum haemorrhage there was no significant difference between Kielland's and ventouse delivery; the rate was lower in Kielland's delivery compared with non‐rotational forceps (RR 0.79, 95% CI 0.65–0.95) and second‐stage CS (RR 0.45, 95% CI 0.36–0.58). There were no differences in the rates of anal sphincter injuries or admission to neonatal intensive care. Rates of shoulder dystocia were higher with Kielland's delivery compared with ventouse delivery (RR 1.79, 95% CI 1.08–2.98), but rates of neonatal birth trauma were lower (RR 0.49, 95% CI 0.26–0.91). There were no differences seen in the rates of 5‐min APGAR score < 7 between Kielland's delivery and other instrumental births, but they were lower when compared with second‐stage CS (RR 0.47, 95% CI 0.23–0.97).ConclusionsKielland's rotational forceps delivery is a safe option for the management of fetal malposition in the second stage of labour.

Published: January 2023

AbstractGreengage wine with low alcohol content is increasing in popularity owing to its fruity taste and rich nutrition. The key to wine aroma and taste is flavor substances like free amino acids (FAAs), volatile fatty acids, higher alcohols, and esters. Amino acid (AA) metabolisms in yeast are an important source of these secondary compounds, which vary with the fermentation conditions. This study explored and optimized the impact of different parameters (carbon source, inoculum, pH, temperature) on FAA contents and dynamics in greengage wine. The results demonstrated that total and essential amino acid (EAA) content rose with a higher proportion of glucose, less yeast inoculation, higher temperature, and higher initial pH. With the results obtained it was concluded that the condition of 22.4°C, pH 4.5, and 3% inoculation was optimum for a 14.9‐fold increase of EAAs in fermented greengage wine. In the long run, the research will aid in the development of the greengage brewing industry.

Published: January 2023

AbstractWalnut green husk (WGH) is rich in natural compounds and is valued as a potential source of antioxidant and antimicrobial properties. In this study, the antioxidant and antimicrobial activities of petroleum ether polar fraction, dichloromethane polar fraction, ethyl acetate polar fraction (EAPF), and n‐butanol polar fraction from WGH were analyzed. The results showed that EAPF exhibited the highest total flavonoid content (65.74 ± 1.01 mg rutin equivalents [RE]/g dry weight [DW]) and total phenol content (48.73 ± 1.09 mg gallic acid equivalent [GAE]/g DW), with the highest 2,2‐diphenyl‐1‐picrylhydrazyl, hydroxyl radical (•OH), and 2,2‐azino‐bis‐3‐ethylbenzothiazoline‐6‐sulfonate scavenging activity compared with other fractions. EAPF also showed good antibacterial activity against Escherichia coli and Bacillus cereus vegetative cells, with a diameter of inhibition zones of 33.5 and 37.6 mm, respectively, a minimum inhibitory concentration of 31.25 mg/ml and a minimum bactericidal concentration of 62.5 mg/ml, which inhibited the growth of both bacteria. Analysis of the antibacterial mechanism demonstrated that EAPF damaged the integrity of the cell membrane, increased the membrane permeability, and triggered the leakage of intracellular material. In addition, ultrahigh performance liquid chromatography‐tandem with mass spectrometry analysis revealed that 8 polyphenols and 14 flavonoids were mainly present in EAPF, such as chlorogenic acid (C16H18O9), gallic acid (C7H6O5), vanillic acid (C8H8O4), ferulic acid (C10H10O4), epicatechin (C15H14O6), catechin (C15H14O6), hesperetin (C16H14O6), naringenin (C15H12O5), hyperin (C21H20O12), luteolin (C15H10O6), and so on. Therefore, WGH had the potential to be developed as a natural antioxidant and antibacterial material.Practical ApplicationOur work indicates that WGH contains abundant flavonoids and polyphenols compounds. Therefore, the plant byproducts like WGH may have a promising application as a source of antimicrobial and antioxidant additives.
Circ_0110498 facilitates the cisplatin resistance of non‐small cell lung cancer by mediating the miR‐1287‐5p/RBBP4 axis
Authors: Hao Dexun , Li Yanshuang , Shi Jiang , Jiang Junguang 
Published: January 2023

AbstractBackgroundCircular RNAs (circRNAs) play vital roles in non‐small cell lung cancer (NSCLC) progression. Our research analyzed the role of circ_0110498 on the cisplatin (DDP) resistance of NSCLC.MethodsCell glycolysis was analyzed by measuring glucose consumption and lactate production. Protein expression was determined by western blot analysis. The expression of circ_0110498, microRNA (miR)‐1287‐5p and RBBP4 was detected by RT‐qPCR assay. Cell counting kit‐8, colony formation and transwell assays, together with flow cytometry were conducted to analyze cell DDP resistance, proliferation, metastasis and apoptosis.ResultsCirc_0110498 expression was elevated in DDP‐resistant NSCLC tissues and cells. Circ_0110498 silencing not only suppressed the DDP resistance of NSCLC cells by inhibiting cell growth, metastasis and glycolysis, but also enhanced the DDP sensitivity of NSCLC tumors. MiR‐1287‐5p was sponged by circ_0110498, and its inhibitor also reversed the effect of circ_0110498 silencing on the DDP resistance of NSCLC cells. MiR‐1287‐5p interacted with RBBP4, and RBBP4 overexpression partly reversed the inhibitory effect of miR‐1287‐5p on the DDP resistance of NSCLC cells.ConclusionCirc_0110498 facilitated DDP resistance partly through mediating the miR‐1287‐5p/RBBP4 signaling in NSCLC.

AbstractBackgroundTo evaluate the surgical safety in myasthenia gravis (MG) patients aged 65 and over.MethodsA total of 564 patients with MG who underwent surgery in the Department of Thoracic Surgery of Beijing Hospital from November 2011 to March 2022 were included in the study and divided into two groups taking the age of 65 as the boundary. Perioperative data of patients were recorded and statistically analyzed.ResultsCompared with young patients, FEV1, FEV1% and MVV in lung function of elderly MG patients were worse (p < 0.001, p < 0.001, p = 0.002). Postoperative drainage time was longer (p < 0.001), combined with more drainage volume (p = 0.002). The American Society of Anesthesiologists (ASA) score of elderly MG patients was higher (p < 0.001). Complications were more likely to occur (p = 0.008) after surgery and Clavien‐Dindo classification (CDC) of postoperative complications was also higher (p = 0.003). Meanwhile, postoperative myasthenic crisis (POMC) was more likely to occur (p = 0.038). Logistic regression showed that lower DLCO% (p = 0.049) was an independent risk factor for postoperative complications.ConclusionsSurgical indications should be considered in each elderly MG patient on an individual basis. Moreover, most elderly MG patients safely survive the perioperative period and benefit from surgery through individualized consideration.
Infrared flashing light through the cricothyroid membrane as guidance to awake intubation with a flexible bronchoscope: A randomised cross‐over study
Authors: Kristensen Michael S. , Hesselfeldt Rasmus , Brinkenfeldt Henning K. , Biro Peter 
Published: January 2023

AbstractBackgroundIn case of distorted airway anatomy, awake intubation with a flexible bronchoscope can be extremely difficult or even impossible. To facilitate this demanding procedure, an infrared flashing light source can be placed on the patient's neck superficial to the cricothyroid membrane. The light travels through the skin and tissue to the trachea, from where it can be registered by the advancing bronchoscope in the pharynx and seen as flashing white light on the monitor. We hypothesised that the application of this technique would allow more proximal and easier identification of the correct pathway to the trachea in patients with severe airway pathology.MethodsAs part of awake intubation, patients underwent insertion of a flexible video bronchoscope via the mouth into the trachea. The procedure was performed twice, in random order in each patient, with and without the aid of the transcutaneous flashing infrared light. All insertions were video recorded to determine at which anatomical landmark within the airway the correct pathway was identified. The videos are accessible via this link: https://airwaymanagement.dk/infrared_comparative. The predefined landmarks were in successive order: oral cavity, oro‐pharynx, tip of epiglottis, arytenoid cartilages, false cords, vocal cords and trachea, as well as the spaces between them.ResultsTwenty‐two patients had a total of 44 awake insertions with the flexible bronchoscope. The median anatomical level, at which correct identification of the trachea was obtained on the monitor, was, past the epiglottis, with the conventional technique, and at the level of the oropharynx, when using the infrared flashing light (p = .005). The time until the flashing light or the vocal cords were seen was 21 (22) S, mean (SD), and 48 (62) S, during the insertion with and without infrared flashing light activated, respectively (p = .005). Endoscopists rated it easier (p = .001) to recognise the entrance to the trachea in the infrared‐group.ConclusionDuring awake intubation of patients with airway pathology, the application of trans‐cricothyroid infrared flashing light to guide the insertion of a flexible bronchoscope significantly facilitated the recognition of the pathway into the trachea and the correct advancement of the flexible endoscope.Registration of Clinical TrialNCT03930550.

Published: January 2023

AbstractImportant changes in the delivery of Veteran emergency care in the early 2000s in the Department of Veteran Affairs (VA) emergency departments and urgent care clinics substantially elevated the role of emergency medicine (EM) in Veteran health care. Focused on enhancing the quality of care, emergency care visits in both VA and non‐VA (community) care locations have nearly doubled from the 1980s to more than 3 million visits in Fiscal Year 2022. Recognizing the need to plan for continued growth and the opportunity to address key research priorities, the VA Office of Emergency Medicine, together with the VA Health Services Research and Development Service, collaborated to convene a State of the Art Conference on Veteran Emergency Medicine (SAVE) in the winter of 2022. The goal of this conference was to identify research gaps and priorities for implementation of policies for three priority groups: geriatric Veterans, Veterans with mental health and substance use complaints, and Veterans presenting to non‐VA (community) emergency care sites. In this article we discuss the rationale for the SAVE conference including a brief history of VA EM and the planning process and conclude with next steps for findings from the conference.
