Knowledge transfer and translation in cultural ecosystems
Authors: Dameri Renata Paola , Demartini Paola 
Published: November 2020

PurposeThis paper concerns the pivotal role that entrepreneurial universities can play in developing knowledge transfer and translation processes tailored to the cultural ecosystem.Design/methodology/approachThe paper examines IncubiAmo Cultura, an innovative project that aims to mentor potential entrepreneurs and offer incubation and acceleration for cultural start-ups. The research methodology is based on action research and theory building from cases. An interventionist approach has been adopted, as one of the authors is also the founder of the ongoing project.FindingsThe in-depth collection of first-hand information on this pilot project has allowed the authors to formulate an analytical reflection and generate the design of a knowledge translation model driven by an entrepreneurial university that manifests itself through the creation of cultural and creative start-ups.Research limitations/implicationsThis article offers an original contribution to scholarship by offering a conceptual model for knowledge translation in cultural ecosystems. Common values (i.e. social, cultural, ethical and aesthetic ones) emerge as the basis on which to build open innovation and knowledge circulation.Practical implicationsFor local policymakers, this study provides a clue to understand the need for both an integrated vision of knowledge translation and policies that aim to make an impact at the cultural ecosystem level. For entrepreneurial university governance, our investigation offers suggestions on the design and implementation of knowledge translation processes that fit with the specificity of the cultural ecosystem. For practitioners in the cultural field, a change of mindset is required to combine resources, energies and knowledge.Originality/valueThis work fills several gaps in the literature, as research generally concerns knowledge transfer from entrepreneurial universities to the market with regard to high-tech sectors. In contrast, the cultural sector is often neglected, despite its importance in the renewal and development of a territory.

Authors: Mao Eric , Soebbing Brian P. , Watanabe Nicholas M. 
Published: November 2020

PurposeUtilizing the capital asset pricing model (CAPM), the purpose is to analyze whether the stock prices of the corporation that owns sport teams fluctuate based on team performance in the Chinese Super League (CSL).Design/methodology/approachSeveral CSL teams are publicly owned corporations. As such, the authors look to see if on-field performance impacts the stock price of the firms. Using the news model from previous research, seemingly unrelated regressions are estimated on CSL games from 2014 through 2017.FindingsThe results from the main models indicate some evidence of a statistical relationship between on-field team performance and stock price. Furthermore, the findings for individual teams across markets did not hold consistent across different markets. More specifically, the authors found some instances where successful on-field performance led to a decline in stock prices.Originality/valueThe present study further contributes to the growing literature related to on-field performance and stock prices. Unlike previous research, the use of the CSL as the empirical setting provides the opportunity to use multiple stock markets which provides an opportunity to further examine this relationship. Finally, the study contributes broadly to the literature on professional sports ownership structures around the world.

Authors: Matsumoto Katsuo 
Published: November 2020

PurposeUsing case studies of business process outsourcing enterprises in India, this study aims to discuss how impact sourcing is used to provide employment opportunities to persons with disabilities (PWDs) and summarizes the business factors associated with successful impact sourcing for PWDs.Design/methodology/approachThe effect of impact sourcing on the employment of PWDs is a newly emerging phenomenon, and this study focuses on the impact-sourcing mechanism and investigates whether such sourcing contributes to promoting PWD employment in India. It does so by examining the business model characteristics of organizations through case studies.FindingsThe results show that effective training systems and operational styles enable continuous market competitiveness for social enterprises. The case studies also demonstrate that it is possible to expand businesses by transferring and replicating management know-how through an organization’s operating model. It also highlights the catalytic role of impact sourcing service providers in promoting formal PWD employment in a labor market where the informal economy is dominant. Central and local governments’ support for social enterprises may promote formal employment of PWDs, an internationally-recognized goal.Originality/valueImpact sourcing for PWDs is an emerging field. This study offers a new contribution to existing work integration social enterprises literature by providing new insight into effective ways of achieving employment for PWDs through outsourcing business. This study highlights the important role of social enterprises in achieving formal employment of PWDs.

ObjectiveTo elucidate the association between sleep disturbances and blood pressure as well as uterine artery Doppler during pregnancy in women with no pre‐existing hypertension.DesignProspective cohort study.SettingOutpatient specialist clinics at KK Women’s and Children’s Hospital, Singapore.PopulationWomen with viable singleton pregnancies confirmed by ultrasonography at less than 14 weeks of amenorrhoea at first visit.MethodsIn all, 926 subjects were recruited for this study in the outpatient specialist clinics at KK Women’s and Children’s Hospital, Singapore, between 1 September 2010 and 31 August 2014. They were followed up throughout pregnancy with sleep quality, blood pressure and uterine artery Doppler assessed at each visit.Main outcome measuresSleep quality, blood pressure and uterine artery Doppler.ResultsSleep progressively worsened as pregnancy advanced. Shorter sleep duration and poorer sleep efficiency were associated with higher blood pressure, especially in the first trimester. Mixed model analysis demonstrated an overall positive association between sleep quality represented by Pittsburgh Sleep Quality Index (PSQI) score and diastolic blood pressure (DBP) (P < 0.001) and mean arterial pressure (MAP) (P = 0.005) during pregnancy after considering all trimesters. Sleep duration was found to be negatively associated with both systolic blood pressure (SBP) (P = 0.029) and DBP (P = 0.002), whereas sleep efficiency was negatively correlated with DBP (P = 0.002) only. Overall poor sleep during pregnancy was also found to be associated with a higher uterine artery pulsatility index.ConclusionOur prospective study demonstrated that poor sleep quality is significantly associated with higher blood pressure and uterine artery pulsatility index during pregnancy.Tweetable abstractPoor sleep quality is significantly associated with higher blood pressure and higher uterine artery pulsatility index during pregnancy.

AbstractBackgroundThere are cases where epidural analgesia is initially effective but subsequently fails and needs to be resited. We evaluated the rate of normal vaginal delivery and operative delivery among parturients who had resited epidurals compared to parturients with epidurals that were not resited.MethodsA retrospective electronic medical review of parturients with a singleton gestation attempting normal vaginal delivery under epidural analgesia between the years 2012‐2016 was conducted. Resited epidurals were defined as epidurals that were considered effective but subsequently removed and reinserted. For each resited epidural, two previous and two consecutive deliveries of parturients with normally functioning epidural catheter inserted by the same anesthesiologist were matched controls (non‐resited epidurals).ResultsThere were 35,984 attempted vaginal deliveries with 118 resited epidurals and 472 non‐resited epidurals. When adjusted for nulliparity, oxytocin administration, sex and weight of the baby, and maternal BMI, labor epidural catheter replacement was not associated with need for instrumental or caesarean delivery, (OR 1.5, 95% CI 0.91‐2.49, P = .11).ConclusionsNeed for labor epidural catheter replacement does not appear to be associated with need for operative delivery based on this single‐centre cohort analysis.

AbstractTo see if variations in timing of rapamycin (Rapa), administered to middle aged mice starting at 20 months, would lead to different survival outcomes, we compared three dosing regimens. Initiation of Rapa at 42 ppm increased survival significantly in both male and female mice. Exposure to Rapa for a 3‐month period led to significant longevity benefit in males only. Protocols in which each month of Rapa treatment was followed by a month without Rapa exposure were also effective in both sexes, though this approach was less effective than continuous exposure in female mice. Interpretation of these results is made more complicated by unanticipated variation in patterns of weight gain, prior to the initiation of the Rapa treatment, presumably due to the use of drug‐free food from two different suppliers. The experimental design included tests of four other drugs, minocycline, β‐guanidinopropionic acid, MitoQ, and 17‐dimethylaminoethylamino‐17‐demethoxygeldanamycin (17‐DMAG), but none of these led to a change in survival in either sex.

AbstractObjectivesNonsteroidal anti‐inflammatory drugs (NSAIDs) and acetaminophen (also called paracetamol) are the most frequent analgesics used to relieve posttrauma pain in the emergency department (ED). However, the utility of combining both treatments is still controversial. We sought to explore the benefits of combining an NSAID with acetaminophen compared to acetaminophen alone, or NSAID alone, in the treatment of posttraumatic pain of the extremity after discharge from the ED.MethodsThis is a prospective, randomized controlled trial, carried out in a single ED from March 2017 to November 2018. The included patients were randomly assigned to receive paracetamol alone, high‐dose NSAID (piroxicam) alone, or a combination of paracetamol and high‐dose NSAID for 7 days after ED discharge. The primary outcome was need for additional oral analgesics. Secondary outcomes included the change of the visual numeric scale (VNS) between ED discharge (VNS D0) and 7 days later (VNS D7), ED revisits for residual pain, side effects, and patient satisfaction as assessed by a Likert satisfaction scale.ResultsThe need for additional oral analgesics was comparable between the paracetamol–NSAID combination group (9.8%) and the paracetamol group (11.4%; p = 0.43). ED readmission rate was also comparable between the two groups at 5.6 and 5.8%, respectively (p = 0.86). In contrast, need for new analgesics and ED revisit rates were both more frequent in the high‐dose NSAID group. Mean VNS decreases on day 7 compared to day 0 were 66, 63, and 67%, respectively, in the paracetamol, NSAID, and paracetamol–NSAID combination groups (p = 0.32). Frequency of dissatisfaction was higher in the NSAID group. Side effects were more frequent in the NSAID and paracetamol–NSAID combination groups.ConclusionThis study found that the combination of a high‐dose NSAID with paracetamol does not increase the analgesic effect compared to paracetamol alone. We also found that paracetamol alone is superior to high‐dose NSAID alone for posttraumatic extremity pain.

AbstractWe present a rare case of De Garengeot hernia treated with simultaneous laparoscopic appendectomy and transabdominal preperitoneal hernia repair. Our patient was an 85‐year‐old man with a bulging mass in the right groin. De Garengeot hernia was observed on contrast‐enhanced CT. Urgent laparoscopy showed the distal part of the appendix passing through a right‐sided femoral hernia. Laparoscopic appendectomy was performed, followed by transabdominal preperitoneal repair of the femoral hernia. Pathological examination revealed ischemic necrosis of the appendix. The patient's postoperative recovery was uneventful.
Perceived teacher support and students’ acceptance of mobile‐assisted language learning: Evidence from Vietnamese higher education context
Authors: Hoi Vo Ngoc , Mu Guanglun Michael 
Published: November 2020

AbstractTeachers play key roles in advancing the use of mobile devices for language learning in both formal and informal settings. However, in contexts where top‐down educational policies are prevalent, the roles of teachers are usually overemphasized while learners–the end‐users of educational technologies remain largely ignored. Less understood is what roles students expect teachers to play in facilitating their acceptance of mobile‐assisted language learning. This study was conducted in an attempt to fill this gap using the extended technology acceptance model (TAM). Survey data from 293 higher education learners of English in Vietnam were analyzed by the Rasch‐based path model. Results indicated that students showed stronger desire for teachers’ orientation toward appropriate use of mobile resources for language learning both inside and outside the classroom than teachers’ demonstration of mobile‐assisted language learning activities in the classroom. The findings offer useful implications for teachers, researchers, and language education policy makers in fostering the use of mobile devices for language learning.
What is already known about this topic?

Teachers’ role in promoting learners’ adoption of mobile‐assisted language learning is under‐researched.
In contexts dominated by top‐down educational policies, the voice of learners is largely ignored.
Learners’ expectation of teachers’ roles in promoting their adoption of mobile‐assisted language learning needs more empirical evidence.
What this paper adds?

This paper highlighted the important roles of teachers in orienting students toward appropriate mobile learning resources for out‐of‐class learning.
Teachers were considered by learners as “guide on the side” rather than “sage on the stage” in enhancing their adoption of mobile‐assisted language learning.
Implications for practice/policy

Teacher training programs on mobile‐assisted language learning can be redesigned to enable teachers to better support mobile‐assisted language learning in and outside the classroom.
Teachers should be better able to enrich their knowledge of various mobile learning resources to support their students.

Published: November 2020

AbstractObjectiveGrowth hormone deficiency (GHD) is usually treated with recombinant human GH (rhGH), and this has been rarely associated with hip disorders. We analysed the clinical data of patients with congenital GHD receiving rhGH who had associated hip dysplasia or Legg‐Calve‐Perthes disease (LCPD), with a view to determining whether the hip dysplasia was associated with the underlying disease or with rhGH treatment.DesignWe performed a retrospective analysis of paediatric and adolescent patients seen between 1992–2018 with congenital GHD and hip disorders. Data were collected through a review of the patients’ medical records and included demographics, clinical and imaging data, and the time frame between the onset of the symptoms related to the hip disorders and the onset of GH treatment.ResultsOf the 13 patients with hip disorders, hip dysplasia was present in ten patients and LCPD in three. Hip dysplasia was diagnosed before rhGH was initiated in 50% of cases. These patients had bilateral hip dysplasia and isolated GHD. LCPD was diagnosed in one patient before rhGH was commenced and did not progress. In two patients, LCPD was diagnosed after rhGH was started and did temporarily progress in one of them, but rhGH was not discontinued because LCPD did not seem to be related to rhGH treatment.ConclusionsThis study suggests that hip dysplasia could be a manifestation of an underlying GHD. Additionally, rhGH treatment may not necessarily be causative of LCPD.
Understanding dispersion of copper phthalocyanine alpha blue pigment in polyethylene masterbatch with the use of wax

Published: November 2020

AbstractColoured plastics and polymers are widely used in packaging and consumer goods. Despite their critical roles, there is limited literature on detailed analysis of effective pigment dispersion in polymer matrices for masterbatch applications. In this study, detailed research was conducted on pigment dispersion using different wax materials and their performances in polyethylene masterbatches were compared. During the study, it was first found that the presence of salt crystals plays a critical role in dispersion in one of the tested pigments. Using a laser particle size device, it was shown that homogeneous particle size distribution is another critical parameter for proper pigment distribution. Although filter testing is a common method in industrial applications, there is very limited information in the academic literature. The filter test method was used to examine the effects of different polyethylene waxes on pigment dispersion. The best filter pressure values were obtained in masterbatches made with micronised wax. It was also observed that the improved dispersion increased the mechanical properties of the masterbatch. The masterbatch colours were measured with a sphere spectrophotometer and it was observed that uniform pigment distribution increased the colour strengths. Similar results were also seen in polyethylene films produced by the blown film process.

Published: November 2020

AbstractObjectivesLong non‐coding RNAs (lncRNAs) are key mediators in various malignancies. Linc01503 was previously elucidated to promote gastric cancer (GC) cell invasion. However, the upstream mechanism of linc01503 and its involvement in GC cell cycle, apoptosis and tumorigenesis still remain unclear.Materials and MethodsBioinformatics analysis and quantitative reverse transcription polymerase chain reaction (qRT‐PCR) assays were implicated to detect linc01503 level in GC. The role of linc01503 was detected by in vitro functional assays and in vivo xenograft tumour models. The association between linc01503 and its upstream effector was identified by chromatin immunoprecipitation (ChIP) assays. The mechanistic model of linc01503 was clarified using subcellular separation, fluorescence in situ hybridization, RNA‐sequencing, RNA immunoprecipitation (RIP) and ChIP assays.ResultsLinc01503 was remarkably elevated in GC and tightly linked with the overall survival of patients with GC. The key transcription factor early growth response protein 1 (EGR1) critically activated the transcription of linc01503. Functionally, linc01503 knockdown resulted in the activation of apoptosis and G1/G0 phase arrest in GC. Mechanistically, linc01503 interacted with histone modification enzyme enhancer of zeste 2 (EZH2) and lysine (K)‐specific demethylase 1A (LSD1), thereby mediating the transcriptional silencing of dual‐specificity phosphatase 5 (DUSP5) and cyclin‐dependent kinase inhibitor 1A (CDKN1A) in GC.ConclusionsEGR1‐activated linc01503 could epigenetically silence DUSP5/CDKN1A expression to mediate cell cycle progression and tumorigenesis, implicating it as a prospective target for GC therapeutics.

AbstractThe standard ‘General requirements for stem cells’ is the first set of general guidelines for stem cell research and production in China, jointly drafted and agreed upon by experts from the Chinese Society for Stem Cell Research. This standard specifies the classification, ethical requirements, quality requirements, quality control requirements, detection control requirements and waste disposal requirements of stem cells, which is applicable to stem cell research and production. It was firstly released by the Chinese Society for Cell Biology on 1 August 2017 and was further revised on 30 April 2020. We hope that publication of these guidelines will promote institutional establishment, acceptance, and execution of proper protocols, and accelerate the international standardization of stem cells for clinical development and therapeutic applications.
The COVID‐19 crisis: A public choice view
Authors: Zweifel Peter 
Published: November 2020

AbstractMany observers have been puzzled by the sight of otherwise freedom‐loving citizens consenting to the stripping of their civil rights and the massive budgetary expansion of their governments in response to the COVID‐19 pandemic. Conversely, governments who ‘kept their cool’ such as those of Brazil and Sweden were heavily criticised by the Western media. Adopting James Buchanan's contractarian approach, this article seeks to model how the interplay between citizens and their government is affected by a health crisis. Citizens' increased willingness to pay for improved control of risks is found to play a major role.
