The match and mismatch between providers and customers in accommodation sharing: a cognitive style perspective
Authors: Chen Aihui , Yu Ying , Lu Yaobin 
Published: April 2021

PurposeThe peer-to-peer (P2P) accommodation-sharing market has developed rapidly on the strength of information technology in recent years. Matching providers and customers in an information technology (IT)-enabled platform is a key determinant of both parties' experiences and the healthy development of the platform. However, previous research has not sufficiently explained the mechanism of provider–customer matching in accommodation sharing, especially at the psychological level. Based on field cognitive style theory, this study examines how the match and mismatch affect customers' online and offline satisfaction and whether a significant difference exists between online and offline satisfaction under different matching patterns.Design/methodology/approachThe authors test the proposed theoretical model using 122 provider–customer dyad data collected through a field study.FindingsThe results suggest that customers' online and offline satisfaction under match is significantly higher than that under mismatch. In addition, customers' online satisfaction is significantly higher than their offline satisfaction under mismatch, but there is no significant difference between the two under match. The perceived price fairness also plays a moderating role in the case of mismatch.Originality/valueIn summary, these findings provide a novel understanding about the matching patterns and their outcomes in the accommodation-sharing context and expand the contents and applications of field cognitive style theory and matching theory. This study will help these IT-enabled platforms to provide personalized matching services at the psychological level, thereby enhancing user experience and corporate competitiveness. 10; 10;
The role of trust in innovation ecosystems
Authors: Steinbruch Fernanda Kalil , Nascimento Leandro da Silva , de Menezes Daniela Callegaro 
Published: April 2021

Purpose
There are indications that trust is essential in innovation ecosystems relations. However, studies have not yet focused on deeply exploring such connection. The purpose of this paper is to discuss the influence of trust among actors in the context of innovation ecosystems.

Design/methodology/approach
This study developed a conceptual framework and a set of propositions. We raised a discussion based on the intertwining of three widely known dimensions of trust (ability, benevolence and integrity) and four dimensions of innovation ecosystems (network collaboration, interdependency, value co-creation and innovation objectives).

Findings
This paper suggests that trust contributes to the development of innovation ecosystems’ dimensions. In addition, it sheds light on the need to consider all three dimensions of trust together and simultaneously, because, by itself, none of them is sufficient to build trust in innovation ecosystems. Also, we argue that the different connections between the dimensions of trust and those of innovation ecosystems lead to the development of such ecosystems.

Originality/value
Through the approach of an underexplored area of research, this paper contributes to a broad understanding of the role of trust in innovation ecosystems toward the pursuit of creating innovation. It also proposes a novelty to the field, by suggesting four dimensions of innovation ecosystems to help managers analyze ecosystems through a more practical perspective.
The missing middle phenomenon in Indian manufacturing sector: myths or realities?
Authors: Parida P. C. , Mitra Arup , Pradhan Kailash Ch. 
Published: April 2021

PurposeThis study attempts to examine the missing middle (MM) phenomena in the context of the Indian manufacturing sector using the unit level information from the database of Ministry of Corporate Affair, Government of India.Design/methodology/approachUnlike the previous studies, the present study first bifurcated the missing enterprises into two categories such as “permanently” dropped and “reappeared,” in order to pursue a meaningful analysis and derive conclusions with policy insights. Various financial indicators were used to explain the causes of MM phenomena during 2009–2010 and 2016–2017, in a logistic framework.FindingsThe study found that profit margin ratio is higher for the group of medium sized enterprises which continued in comparison to the units which dropped out permanently. Similar is the case with the ratio of investment turnover. The econometric results, however suggest that the relationship between the chances of a firm being dropped out and financial indicators is weak as the coefficients of various financial indicators are found to be statistically significant only for a few years.Originality/valueThe study suggests that the missing middle phenomenon is not a myth in India as very large number of medium-sized firms have been disappearing from the market over the years. Based on firm level data it identifies the factors which resulted in such a phenomenon.

PurposeThe citation counts are an important indicator of scholarly impact. The purpose of this paper is to explore the correlation between citations of scientific articles and writing styles of abstracts in papers and capture the characteristics of highly cited papers' abstracts.Design/methodology/approachThis research selected 10,000 highly cited papers and 10,000 zero-cited papers from the WOS (2008-2017) database. The Coh-Metrix 3.0 textual cohesion analysis tool was used to quantify the 108 language features of highly cited and zero-cited paper abstracts. The differences of the indicators with significant differences were analyzed from four aspects: vocabulary, sentence, syntax and readability.FindingsThe abstracts of highly cited papers contain more complex and professional words, more adjectives, adverbs, conjunctions and personal pronouns, but fewer nouns and verbs. The sentences in the abstracts of highly cited papers are more complex and the sentence length is relatively longer. The syntactic structure in abstracts of highly cited papers is relatively more complex and syntactic similarities between sentences are fewer. Highly cited papers' abstracts are less readable than zero-cited papers' abstracts.Originality/valueThis study analyses the differences between the abstracts of highly cited and those of zero-cited papers, reveals the common external and deep semantic features of highly cited papers in abstract writing styles, provide suggestions for researchers on abstract writing. These findings can help increase the scientific impact of articles and improve the review efficiency as well as the researchers' abstract writing skills.

Authors: Cao Huiliang , Cui Rang , Liu Wei , Ma Tiancheng , Zhang Zekai , Shen Chong , Shi Yunbo 
Published: April 2021

Purpose
To reduce the influence of temperature on MEMS gyroscope, this paper aims to propose a temperature drift compensation method based on variational modal decomposition (VMD), time-frequency peak filter (TFPF), mind evolutionary algorithm (MEA) and BP neural network.

Design/methodology/approach
First, VMD decomposes gyro’s temperature drift sequence to obtain multiple intrinsic mode functions (IMF) with different center frequencies and then Sample entropy calculates, according to the complexity of the signals, they are divided into three categories, namely, noise signals, mixed signals and temperature drift signals. Then, TFPF denoises the mixed-signal, the noise signal is directly removed and the denoised sub-sequence is reconstructed, which is used as training data to train the MEA optimized BP to obtain a temperature drift compensation model. Finally, the gyro’s temperature characteristic sequence is processed by the trained model.

Findings
The experimental result proved the superiority of this method, the bias stability value of the compensation signal is 1.279 × 10–3°/h and the angular velocity random walk value is 2.132 × 10–5°/h/vHz, which is improved compared to the 3.361°/h and 1.673 × 10–2°/h/vHz of the original output signal of the gyro.

Originality/value
This study proposes a multi-dimensional processing method, which treats different noises separately, effectively protects the low-frequency characteristics and provides a high-precision training set for drift modeling. TFPF can be optimized by SEVMD parallel processing in reducing noise and retaining static characteristics, MEA algorithm can search for better threshold and connection weight of BP network and improve the model’s compensation effect.

Authors: Cheng Leyi , Wang Yinghan , Peng Yichuan 
Published: April 2021

Purpose
The causes of high-speed railway failures are complex, and it is difficult to quantitatively and accurately describe safety evaluation. The purpose of this paper is to construct a model to ensure the safety of high-speed railway operations.

Design/methodology/approach
The authors construct a high-speed railway operation safety evaluation index system from four aspects: personnel, equipment, environment and management and analyze the inter-coupling relationship of various safety factors. Based on the evaluation index system, the use of network analytic hierarchy process (ANP) and fuzzy comprehensive evaluation will be used to establish a high-speed railway operation safety evaluation model.

Findings
Through the literature investigation and field investigation, combined with high-speed railway safety key points and system composition, 4 first-level indicators and 17 second-level indicators were selected to construct a high-speed railway operation safety evaluation index system. It can be seen from the results that the personnel management system and the signal and control system have the largest weight.

Originality/value
On the basis of establishing an evaluation index system, comprehensively considering the internal coupling relationship between evaluation indexes and the fuzziness of high-speed railway operation safety evaluation, high-speed railway uses ANP fuzzy network analysis method to construct high-speed railway operation, and the safety evaluation model has certain advantages and practicability in the case of the relative lack of high-speed railway operation data and fault data.
Artificial Intelligence and Liability in Medicine: Balancing Safety and Innovation
Authors: MALIHA GEORGE , GERKE SARA , COHEN I. GLENN , PARIKH RAVI B. 
Published: April 2021

Policy Points
With increasing integration of artificial intelligence and machine learning in medicine, there are concerns that algorithm inaccuracy could lead to patient injury and medical liability.
While prior work has focused on medical malpractice, the artificial intelligence ecosystem consists of multiple stakeholders beyond clinicians. Current liability frameworks are inadequate to encourage both safe clinical implementation and disruptive innovation of artificial intelligence.
Several policy options could ensure a more balanced liability system, including altering the standard of care, insurance, indemnification, special/no‐fault adjudication systems, and regulation. Such liability frameworks could facilitate safe and expedient implementation of artificial intelligence and machine learning in clinical care.

AbstractBackgroundA causative relationship between varicocele and impairment of semen quality has been largely investigated in the context of male infertility, although its clinical benefit remains controversial.ObjectiveTo investigate the effect of varicocele correction on detailed morphologic microscopic semen parameters in a large homogeneous cohort of patients and to evaluate which factors could predict semen improvement after the surgical treatment.Materials and methodsAn observational, retrospective cohort study was carried out including all patients undergoing surgical treatment for varicocele from September 2011 to March 2020 in the same clinical centre. Enrolled males performed at least one semen analysis before and one after surgical varicocele correction. Primary outcome was the detailed morphologic microscopic sperm evaluation. Secondary outcomes were conventional semen analyses.ResultsA total of 121 males (mean age 24.6 ± 6.1 years) were enrolled. Using detailed morphologic microscopic sperm evaluation, a significant morphological improvement was recorded, with a reduction in head and tail abnormalities. Moreover, a significant increase in sperm concentration (p = 0.015) and percentage of progressive and total motility (p = 0.022 and p = 0.039) were observed after surgery. The multivariate logistic analysis identified the ultrasonography varicocele degree before surgery as a main predictor of the sperm concentration improvement (p = 0.016), with the highest improvement for varicocele of I and II degree.DiscussionFor the first time, the detailed morphologic microscopic sperm evaluation highlights a relevant reduction in sperm abnormalities after varicocele surgery, showing its potential application in clinical practice.

AbstractBackgroundHead and neck surgeons are moving away from routine tracheostomy in free‐flap reconstruction. We reviewed prophylactic tracheostomy use in patients undergoing oral cavity or oropharynx free‐flap reconstruction to identify patient groups who avoided tracheostomy. Secondary aims were to describe complications associated with and without tracheostomy.MethodsA retrospective cohort study was undertaken, using a prospectively maintained database. Inclusion criteria was free‐flap reconstruction for an oral cavity or oropharyngeal defect, excluding partial or total laryngectomy. Variables collected included demographics, comorbidity, American Society of Anesthesiologists grade, Charlson Comorbidity Index, tumour site and subsite, extent of resection, surgery duration, tracheostomy, complications, return to theatre and re‐intubation.ResultsA total of 344 head and neck free‐flap reconstructions were performed between January 2017 and July 2019. A total of 164 (87.7%) oral cavity and 23 (12.3%) oropharyngeal reconstructions were included totalling 187 free flaps. A total of 107 (57.2%) were males and 80 (42.8%) females, mean age 62.4 years (range 21–89). Of 187 patients, 100 (53.5%) underwent prophylactic tracheostomy at time of reconstruction. Longer operative time (P < 0.001), resection site (P < 0.001), number of subsites resected (P = 0.007), segmental mandibulectomy (P = 0.04), lip‐split (P = 0.05), floor of mouth resection (P < 0.001), lingual release (P = 0.007), glossectomy (P < 0.001), extent of tongue resection (P < 0.001), extent of hard palate resection (P = 0.04), soft palate resection (P < 0.001) and double free‐flap reconstruction (P = 0.04) were associated with tracheostomy use.ConclusionA personalized approach to postoperative airway management allowed almost half of our cohort to avoid tracheostomy. In high‐volume institutions with the necessary expertise and support, appropriately selected patients may be safely managed without routine tracheostomy.

Published: April 2021

BackgroundIt is well established that successful learning with multimedia is challenging, especially for younger learners.AimsIt was investigated whether students would profit from instructional support regarding the use of multimedia learning strategies.SampleParticipants were high school students in 8th, 9th, and 10th grade (N = 168).MethodsParticipants were assigned to a no‐support control group or one of four experimental groups. In the experimental groups, students received either only a multimedia strategy training before learning (training group) or the training was enriched by prompts (prompts before or during learning) or if‐then plans (implementation intentions). In the training, multimedia learning strategies were introduced (e.g., linking information from text and picture). The prompts and implementation intentions were aimed at enhancing the application of the multimedia strategies conveyed through the training. Students learned about the process of mitosis by studying multimedia instructions and were tested regarding the acquired knowledge. It was expected that solely training students to use adequate multimedia learning strategies would not promote learning compared with the control group, rather, that additional support like prompts or implementation intentions would be necessary to enhance learning.ResultsAlthough in the experimental groups, multimedia learning strategies were used more frequently especially in the beginning of the instructional unit, there were no effects on learning outcome.ConclusionsPromoting multimedia strategy use did not improve learning. The quality of the different instructional support measures and their suitability for the target groups are discussed as possible explanations for these findings.

Published: April 2021

ObjectiveTo compare patient‐reported outcome measures in patients with and without abdominal wall complications after open partial nephrectomy (OPN) via flank incision.Patients and MethodsPatient‐reported outcome measures were collected in 2017 from all patients operated on with OPN via flank incision between 2004 and 2016 in Västerbotten County, Sweden. Patients were mailed the ventral hernia pain questionnaire (VHPQ) and an abdominal wall asymmetry (AWA) questionnaire to evaluate postoperative AWA, attributed to bulge or incisional hernia. Demographic and follow‐up data were retrieved from patient records.ResultsA total of 198 patients were eligible for the study, and 146 questionnaires were returned (74%). Forty‐five patients (31%) reported postoperative AWA and 27 (18%) reported ongoing pain. Three patients who reported AWA had a known incisional hernia. Pain and abdominal wall stiffness were more common in patients with AWA than in those without (P < 0.01 and P < 0.01, respectively). Of the 45 patients with AWA, 25 (56%) reported this as being negative cosmetically and 16 (36%) as negative regarding activities. Patients that reported AWA were younger and had a higher body mass index at surgery (P = 0.03 and 0.04, respectively).ConclusionAbdominal wall asymmetry is a common sequel of flank incision for OPN and is associated with a higher incidence of chronic pain and abdominal stiffness compared to absence of postoperative AWA. Some patients reported that the effect on daily activities and the cosmetic effect caused by AWA had a negative impact on their quality of life.

Published: April 2021

AbstractKrabbe disease (KD), also known as globoid cell leukodystrophy, is an inherited demyelinating disease caused by the deficiency of lysosomal galactosylceramidase (GALC) activity. Most of the patients are characterized by early‐onset cerebral demyelination with apoptotic oligodendrocyte (OL) death and die before 2 years of age. However, the mechanisms of molecular pathogenesis in the developing OLs before death and the exact causes of white matter degeneration remain largely unknown. We have recently reported that OLs of twitcher mouse, an authentic mouse model of KD, exhibit developmental defects and endogenous accumulation of psychosine (galactosylsphingosine), a cytotoxic lyso‐derivative of galactosylceramide. Here, we show that attenuated expression of microRNA (miR)‐219, a critical regulator of OL differentiation and myelination, mediates cellular pathogenesis of KD OLs. Expression and functional activity of miR‐219 were repressed in developing twitcher mouse OLs. By using OL precursor cells (OPCs) isolated from the twitcher mouse brain, we show that exogenously supplemented miR‐219 effectively rescued their cell‐autonomous developmental defects and apoptotic death. miR‐219 also reduced endogenous accumulation of psychosine in twitcher OLs. Collectively, these results highlight the role of the reduced miR‐219 expression in KD pathogenesis and suggest that miR‐219 has therapeutic potential for treating KD OL pathologies.

AbstractThe use of rapid DNA sequencing technology in severely ill children in developed countries can accurately identify diagnoses and positively impact patient outcomes. This study sought to evaluate the outcome of Thai children and adults with unknown etiologies of critical illnesses with the deployment of rapid whole exome sequencing (rWES) in Thailand. We recruited 54 unrelated patients from 11 hospitals throughout Thailand. The median age was 3 months (range, 2 days–55 years) including 47 children and 7 adults with 52% males. The median time from obtaining blood samples to issuing the rWES report was 12 days (range, 5–27 days). A molecular diagnosis was established in 25 patients (46%), resulting in a change in clinical management for 24 patients (44%) resulting in improved clinical outcomes in 16 patients (30%). Four out of seven adult patients (57%) received the molecular diagnosis which led to a change in management. The 25 diagnoses comprised 23 different diseases. Of the 34 identified variants, 15 had never been previously reported. This study suggests that use of rWES as a first‐tier investigation tool can provide tremendous benefits in critically ill patients with unknown etiology across age groups in Thailand.
