Robots are coming to the libraries: are librarians ready to accommodate them?
Authors: Tella Adeyinka 
Published: June 2020

Purpose
This paper aims to examine the coming of robots to libraries and the readiness of their hosts who are the librarians in welcoming and accommodating them.

Design/methodology/approach
A conceptual and review analysis of documents was adopted to determine the types of robots used in libraries along with their duties, the librarians’ readiness and the likes.

Findings
There is the fear that the coming of robots to libraries is to take the librarians job; contrarily the arrival of robots to the library is not to replace the librarians but rather to complement their efforts.

Originality/value
The paper is the original idea by the authors, and it is to get the librarians with limited skills in libraries prepared for up-skilling if they do not want to be replaced by the robots.

Published: June 2020

PurposeThe evolution of Knowledge-Management (KM)-related literature has highlighted that Knowledge Management Systems (KMSs) have undergone massive changes in collaborative environments. Information-Systems-enabled KM seems to be the necessary response to the recent challenges posed by globalisation and technology dynamics to both large companies (LCs) and small and medium enterprises (SMEs).Design/methodology/approachThis paper provides a systematic review about KMSs to offer an analytical overview of their role in supporting innovative forms of knowledge translation occurring in collaborative relationships. A sample of 129 papers was selected and analysed according to three perspectives: unit of analysis (LCs, SMEs), phases of the KM process (adoption, translation) and topic area (KM Practices, KM Tools, KMSs).FindingsThe findings highlight five literature gaps: (1) the role of KM practices supporting knowledge translation; (2) the impact of the alignment among KM practices, firm's complexity, dimension and culture on KM process; (3) the effect of KM tools on knowledge translation; (4) the variety of KMSs exploited in both LCs and SMEs; and (5) the alignment between organisational structure and information systems in KM context. Accordingly, 13 research questions were formulated.Originality/valueThe proposed research questions define a formal research agenda that could steer further research efforts about the KMS topic for improving the body of knowledge in the KM field. Scientific literature is currently lacking a contribution assessing the role of KMSs in supporting innovative forms of knowledge translation that occur in collaborative relationships.
Towards the development of a smart fused filament fabrication system using multi-sensor data fusion for in-process monitoring
Authors: Moretti Michele , Bianchi Federico , Senin Nicola 
Published: June 2020

Purpose
This paper aims to illustrate the integration of multiple heterogeneous sensors into a fused filament fabrication (FFF) system and the implementation of multi-sensor data fusion technologies to support the development of a “smart” machine capable of monitoring the manufacturing process and part quality as it is being built.

Design/methodology/approach
Starting from off-the-shelf FFF components, the paper discusses the issues related to how the machine architecture and the FFF process itself must be redesigned to accommodate heterogeneous sensors and how data from such sensors can be integrated. The usefulness of the approach is discussed through illustration of detectable, example defects.

Findings
Through aggregation of heterogeneous in-process data, a smart FFF system developed upon the architectural choices discussed in this work has the potential to recognise a number of process-related issues leading to defective parts.

Research limitations/implications
Although the implementation is specific to a type of FFF hardware and type of processed material, the conclusions are of general validity for material extrusion processes of polymers.

Practical implications
Effective in-process sensing enables timely detection of process or part quality issues, thus allowing for early process termination or application of corrective actions, leading to significant savings for high value-added parts.

Originality/value
While most current literature on FFF process monitoring has focused on monitoring selected process variables, in this work a wider perspective is gained by aggregation of heterogeneous sensors, with particular focus on achieving co-localisation in space and time of the sensor data acquired within the same fabrication process. This allows for the detection of issues that no sensor alone could reliably detect.
Mechanical, thermal, melt-flow and morphological characterizations of bentonite-filled ABS copolymer
Authors: Alhallak Laylay Mustafa , Tirkes Seha , Tayfun Umit 
Published: June 2020

PurposeThis study aims to investigate the mechanical, thermal, melt-flow and morphological behavior of acrylonitrile-butadiene-styrene (ABS)-based composites after bentonite inclusions. Melt mixing is the most preferred production method in industrial scale and basically it has very near processing parameters compared to 3D printing applications. Rheological parameters of ABS and its composites are important for 3D applications. Melt flow behavior of ABS effects the fabrication of 3D printed product at desired levels. Shear thinning and non-Newtonian viscosity characteristics of ABS make viscosity control easier and more flexible for several processing techniques including injection molding, compression molding and 3D printing.Design/methodology/approachABS copolymer was reinforced with bentonite mineral (BNT) at four different loading ratios of 5%, 10%, 15% and 20%. ABS/BNT composites were fabricated by lab-scale micro-compounder followed by injection molding process. Mechanical, thermo-mechanical, thermal, melt-flow and morphological properties of composites were investigated by tensile, hardness and impact tests, dynamic mechanical analysis (DMA), thermo-gravimetric analysis (TGA), melt flow index (MFI) test and scanning electron microscopy (SEM), respectively.FindingsMechanical tests revealed that tensile strength, elongation and hardness of ABS were enhanced as BNT content increased. Glass transition temperature and storage modulus of ABS exhibited increasing trend with the additions of BNT. However, impact strength values dropped down with BNT inclusion. According to MFI test measurements, BNT incorporation displayed no significant change for MFI value of ABS. Homogeneous dispersion of BNT particles into ABS phase was deduced from SEM micrographs of composites. Loading ratio of 15% BNT was remarked as the most suitable candidate among fabricated ABS-based composites according to findings.Research limitations/implicationsThe advanced mechanical properties and easy processing characteristics are the reasons for usage of ABS as an engineering plastic. Owing to the increase in its usage for 3D printing technology, the ABS became popular in recent years. The utilization of ABS in this technology is in filament form with various colors and dimensions. This is because of its proper rheological features.Practical implicationsMelt-mixing technique was used as preparation of composites, as this processing method is widely applied in industry. This method is also providing similar processing methodology with 3D printing technology.Originality/valueAccording to the literature survey, to the best of the authors’ knowledge, this study is the first research work regarding the melt-flow performance of ABS-based composites to evaluate their 3D printing applications and processability. ABS and BNT containing composites were characterized by tensile, impact and shore hardness tests, DMA, TGA), MFI test and SEM techniques.
Management response to eWOM in rural lodging establishments
Authors: Hernández-Maestro Rosa M. 
Published: June 2020

Purpose
Companies are adopting a more active role in managing their online reputations by using electronic word of mouth (eWOM) and often responding directly to customer reviews. Therefore, companies need to understand the effects of management responses to customer reviews. This study aims to explore whether it is worth responding to reviews and whether expressing gratitude enhances the effects of review responses.

Design/methodology/approach
This study uses customer reviews and management response data from a sample of 766 Spanish rural lodging establishments listed on Toprural (www.toprural.com). Analyses are undertaken with NVivo and SmartPLS.

Findings
Responding to negative reviews improves lodging establishments’ average ratings, but responding to positive reviews has no significant direct effect. Expressing gratitude in responses positively moderates the effects of review responses; this moderating effect is more significant for responses to negative than to positive reviews.

Originality/value
Previous research provides contradictory evidence about the positive outcomes of a company’s responses; it also does not address expressions of gratitude. This research provides evidence of the direct effects of management response quantity on ratings. It also expands current research on the content characteristics of these responses. The contextual setting for this research, rural tourism, is a key driver of sustainable rural development and a sector in which eWOM is especially relevant; thus, correctly managing the eWOM phenomenon becomes crucial.
Overcoming adversity: a grounded theory of health management among middle‐aged and older gay men
Authors: Handlovsky Ingrid , Bungay Vicky , Johnson Joy , Oliffe John 
Published: June 2020

AbstractThis article presents findings from a grounded theory study in which we explored how self‐identifying gay men between 40 and 76 years of age manage their health in the context of homophobia, heteronormativity and discrimination. Data were collected with 25 men over a 6‐month period in a large urban setting in Western Canada. A preliminary theory of health management is discussed, consisting of the central phenomenon of overcoming adversity. Three thematic processes are considered that illustrate how adversity and health management are situated within the interrelationships of historical and ongoing discrimination inclusive of and external to the healthcare encounter, the complexity of men’s illnesses, and the temporal aspects of HIV epidemics and treatments that occurred throughout their lives. These themes include: advocating for health needs, knowing about health issues and treatments, and engaging in health promoting practices. These findings help to address a gap in knowledge concerning health management among older gay men and support that initiatives aimed at health care with gay men must appreciate the systemic role of discrimination, while supporting men’s individual efforts in actively managing their health.

Published: June 2020

AbstractObjectiveTo study characteristics and outcomes of patients with stroke, traumatic brain injury (TBI), and epilepsy with discharge against medical advice (DAMA).Data Sources/Study SettingRetrospective analysis of the 2013 Nationwide Readmissions Database, a nationally representative inpatient administrative dataset.Study DesignAssociations between predictors and DAMA at index admission were analyzed using adjusted logistic models. We examined 30‐day all‐cause readmissions.Data Collection MethodsPatients aged ≥18 years at index admission for International Classification of Diseases‐9 diagnosis code of epilepsy, TBI, or stroke were included.Principal FindingsDischarge against medical advice occurred in 1998/58278 patients (3.43 percent) in the epilepsy group, 1762/211 213 (0.83 percent) in the stroke group, and 1289/74 652 (1.73 percent) in the TBI group. Factors consistently associated with increased likelihood of DAMA included lower age, male sex, non‐Medicare and nonprivate insurance, lower socioeconomic status, and behavioral risk factors (smoking history, alcohol history, and drug use). The crude 30‐day all‐cause readmission rate for those with DAMA from their index admission was 16.4 percent for the stroke cohort, 13.9 percent for epilepsy, and 13.4 percent for TBI. DAMA at index admission was significantly associated with increased risk of 30‐day all‐cause readmission among all groups (adjusted odds ratio 1.79, 95% CI: 1.65‐1.94, P < .0001).ConclusionsAge, sex, insurance status, socioeconomic status, and behavioral factors were associated with DAMA in neurological patients. Further research is needed to develop interventions to reduce DAMA in high‐risk groups.
What proportion of healthcare worker masks carry virus? A systematic review
Authors: Jones Peter , Roberts Sally , Hotu Cheri , Kamona Sinan 
Published: June 2020

AbstractObjectiveConcerns have been raised by healthcare organisations in New Zealand that routine mask use by healthcare workers (HCW) may increase the risk of transmission of SARS‐CoV‐2 through increased face touching. Routine mask use by frontline HCW was not recommended when seeing ‘low risk’ patients. The aim of this review was to determine the carriage of respiratory viruses on facemasks used by HCW.MethodsA systematic review was conducted with structured searches of medical and allied health databases. Two authors independently screened articles for inclusion, with substantial agreement (k = 0.66, 95% CI 0.54–0.79). Studies that at least one author recommended for full text review were reviewed in full for inclusion. Two authors independently extracted data from included studies including the setting, method of analysis and results. There was exact agreement on the proportion of virus detected on masks.ResultsWe retrieved 1233 titles, 47 underwent full text review and five studies reported in four articles were included. The studies were limited by small numbers and failure to test all eligible masks in some studies. The proportion in each study ranged from 0 (95% CI 0–10) to 25% (95% CI 8–54). No study reported clinical respiratory illness as a result of virus on the masks.ConclusionsAlthough limited, current evidence suggests that viral carriage on the outer surface of surgical masks worn by HCW treating patients with clinical respiratory illness is low and there was not strong evidence to support the assumption that mask use may increase the risk of viral transmission.

AbstractTo improve the accuracy of forecasting the peak occurrence of Dendrolimus punctatus Walker, we here used the Bayes discriminant analysis to predict this peak occurrence for the first and second generation of Dendrolimus punctatus larvae based on these data from 1983 to 2016 in Qianshan County, Anhui Province. Our present results showed that this discriminant equation for the first generation was as follows: f(1) = −3.2588‐6.2700x1 + 1.2870x2 + 0.7920x3 + 0.4152x4; f(2) = −14.5215‐8.5710x1 + 2.9790x2 + 2.0280x3 + 0.5031x4; f(3) = −3.5264; f(4) = −66.8312‐12.5216x1 + 5.1740x2 + 4.7162x3 + 0.6033x4. And that the prediction accuracy for the first generation was 97.22%. Whilst this discriminant equation for the second generation was as follows: f(1) = −3.536‐1.192x5 + 1.338x6 + 0.638x7−0.025x8; f(2) = −7.317‐1.337x5 + 4.240x6 + 1.010x7−0.295x8; f(3) = −16.488‐3.192x5 + 4.955x6 + 1.900x7–0.411x8; f(4) = −34.502‐4.184x5 + 7.484x6 + 2.583x7–0.443x8. The prediction accuracy for the second generation was 85.71%. Overall, our findings revealed that the Bayes discriminant analysis could screen out key factors to significantly improve the prediction accuracy of peak occurrence of Dendrolimus punctatus larvae.

Published: June 2020

AbstractThis study verified the formation profile of esters of 3‐monochloropropane‐1,2‐diol (3‐MCPDE), 2‐monochloropropane‐1,2‐diol (2‐MCPDE), and glycidol (GE), and evaluated the physicochemical changes (free‐fatty acid, acylglycerols, and colour) that occurred during the deodorization of palm oil in different conditions of time (30, 60, 90, and 120 min) and temperature (210, 230, 250, and 270 °C). Levels of 3‐MCPD and 2‐MCPD esters ranged from 1.91 to 2.70 mg/kg and 0.68 to 1.44 mg/kg, respectively, and were formed at the mildest tested condition (210 °C, 30 min). No correlation was observed between these contaminants and physicochemical changes. GE levels varied from 0.12 to 8.51 mg/kg and showed correlation with color and diacylglycerol content. While the temperature had little influence on the formation of esters of 3‐MCPD and 2‐MCPD, the content of GE considerably raised above 250 °C.

Published: June 2020

AbstractAcrylamide (AA), classified as a probable carcinogen, can be neurotoxic, genotoxic, and can damage DNA. This study explored the ability of seabuckthorn berries juice (SBJ) to alleviate AA‐induced toxic injury in rats. Twenty‐four adult male Sprague‐Dawley (SD) rats were randomly divided into four groups: control group, AA group (40 mg/kg), AA + SBJ (40 mg/kg AA and 5 mL/kg SBJ), and AA + vitamin C (VC) group (positive control group, 40 mg/kg AA and 100 mg/kg VC). At the end of the experiment, rats in AA group showed a marked decrease in the rate of weight gain, hind extremity abduction, and ataxia. Obvious anomalies were seen in plasma biochemical parameters (P < 0.05), and different degrees of injury were observed upon histological examination of five tissues (hippocampus, cerebellum, liver, small intestine, and kidney). Compared to the control group, levels of superoxide dismutase, catalase, and glutathione were significantly decreased, while malondialdehyde was elevated (P < 0.05). SBJ treatment reduced the abnormal of behavior, hematological index, antioxidant enzyme, and tissue damage caused by AA in rats.Practical ApplicationSeabuckthorn berries are wild berries rich in vitamin C and polyphenols, which have good antioxidant properties. In this experiment, SBJ has a significant alleviating effect on AA‐induced oxidative damage in rats. Therefore, we speculate that SBJ may relieve the oxidative damage caused by diet or other forms of AA exposure in the general population. At the same time, this experiment also provides new ideas for alleviating AA‐induced in vivo toxicity.

Published: June 2020

AbstractMicroencapsulation by production of polymer beads from ionic gelation is a useful method to improve the stability of nutritional compounds. Wheat germ oil is a nutritional source of unsaturated fatty acids and phytonutrients, such as tocopherols (α and β), phytosterols, carotenoids, and phenolic compounds. This work studied the development of alginate‐starch beads over the stability of encapsulated wheat germ oil. The beads contained sodium alginate and gelatinized corn starch in proportions of 2:0, 1:1, 1:2, and 1:4. The addition of small amounts (1:1) of gelatinized starch in the alginate emulsions improved the physicochemical properties and stability during storage. The emulsions had oil droplets with mean sizes ranging from 4.5 to 12.2 µm. The 1:1 samples showed more disperse oil droplets, explained by the molecular interaction between the starch chains and oil. The encapsulation efficiency was higher than 91%, and the beads’ mean diameters were between 383.22 and 797.45 µm. The proportion of 1:1 alginate‐starch also enhanced the beads’ microstructures, avoiding oil oxidation. Six days accelerated stability (65 °C) evidenced higher tocopherols amounts (0.66 mg/g oil) and a lower oxidation (2.52 meq.O2/kg oil) for the 1:1 samples compared to the remained samples.Practical ApplicationAlginate‐gelatinized corn starch beads loaded with wheat germ oil can be used as an ingredient in functional food products for the enrichment of nutrients. The use of starch decreased the oil oxidation and the loss of tocopherols during storage, indicating that the quality of the wheat germ oil will be desirable for longer durations of food storage.
Efficacy and safety of endoscopic submucosal tunnel dissection vs endoscopic submucosal dissection for early superficial upper gastrointestinal precancerous lesions and tumors: A meta‐analysis
Authors: Liu Yu Zhi , Lv Xiu He , Deng Kai , Yang Jin Lin 
Published: June 2020

ObjectiveEndoscopic submucosal tunnel dissection (ESTD) is a new treatment for superficial upper gastrointestinal precancerous lesions and tumors. However, its safety and efficacy for treating these lesions is still uncertain. This meta‐analysis aimed to compare the efficacy and safety of ESTD with those of endoscopic submucosal dissection (ESD) in treating early superficial upper gastrointestinal precancerous lesions and tumors.MethodsElectronic databases, including EMBASE, PubMed, Cochrane Library and the Web of Science, were systematically searched for articles published up to 1 April 2020. The primary outcomes were complete and en bloc resection rates of the lesions. The secondary outcomes included operation time, speed of dissection, complication and recurrence rates. The Newcastle‐Ottawa quality assessment scale was used to evaluate the quality of the studies.ResultsSeven studies were included in the final meta‐analysis. The complete and en bloc resection rates of early superficial esophageal lesions as well as the en bloc resection rate of early superficial gastric lesions were similar between the ESTD and ESD groups. Compared with the ESD group, the ESTD group had a higher en bloc resection rate for early superficial gastric lesions. A faster dissection speed was observed in both superficial esophageal and gastric lesions. In gastric lesions, the operation time of the ESTD group was shorter than that of the ESD group, while it did not differ for esophageal lesions. There were no obvious differences in bleeding and perforation rates between the groups.ConclusionAs an endoscopic technique for treating early superficial upper gastrointestinal lesions, ESTD is as safe as and more effective than ESD, especially for gastric lesions.
