Job insecurity and impression management
Authors: Probst Tahira M. , Jiang Lixin , López Bohle Sergio Andrés 
Published: August 2019

PurposeThe purpose of this paper is to test competing models of the relationship between job insecurity and two forms of impression management (self- and supervisor-focused) on job performance. Specifically, does job insecurity lead to greater subsequent impression management; or, does preventative use of impression management subsequently lead to reductions in job insecurity? Additionally, how do these both relate to in-role performance?Design/methodology/approachUsing two-wave survey data collected from 184 working adults in the USA and the two-step approach recommended by Cole and Maxwell (2003) and Taris and Kompier (2006), the authors tested cross-lagged relationship between job insecurity and both forms of impression management by comparing four different models: a stability model, a normal causation model (with cross-lagged paths from T1 job insecurity to T2 impression management), a reversed causation model (with cross-lagged paths from T1 impression management to T2 job insecurity) and a reciprocal causation model (with all cross-lagged paths described in the normal and reversed causation model).FindingsResults were supportive of the reversed causation model which indicated that greater use of supervisor-focused impression management at Time 1 predicted lower levels of job insecurity at Time 2 (after controlling for prior levels of job insecurity); moreover, job insecurity at Time 1 was then significantly associated with more positive in-role behaviors at Time 2. Moreover, the test of the indirect effect between T1 impression management and T2 performance was significant.Originality/valueThese results suggest that impression management clearly plays an important role in understanding the relationship between job insecurity and job performance. However, employees appear to utilize impression management as a means of pre-emptively enhancing their job security, rather than as a tool to reactively cope with perceived job insecurity.
Design and application of integrated parabolic soft actuator
Authors: Liu Dong , Wang Minghao , Cong Ming 
Published: August 2019

Purpose
The purpose of this paper is to solve the common problems of outer phenomenon and stress concentration among pneumatic networks soft actuators.

Design/methodology/approach
On the basis of imitating the caterpillar structure, the new soft actuator adopts the integral circular ladder structure instead of the traditional independent distributed structure as the air chamber. Through the comparison of several different structures, the parabolic in-wall curve is found to be fit for designing the optimal integrated chamber structure of the soft actuator. The curve function of each ladder chamber is computed based on the torque distribution model, aiming to decrease the terminal deformation. Meanwhile, the FEM analysis method is applied to establish the motion model of the integrated parabolic ladder soft actuator. The model’s accuracy, as well as structure’s deformation and stress, are verified.

Findings
Compared with the FEM data, the experimental data indicate that the new soft actuator has no obvious outer phenomenon, the maximum stress decreases and the stiffness increases. The new actuator is applied for designing a flexible gripper to grasp objects of different shapes and sizes. The gripper can grasp objects of 52.6 times its own mass.

Practical implications
The designed gripper is available for flexible production in various fields, such as capturing fruits of different sizes, soft foods or parts with complex shapes.

Originality/value
This paper proposes a new type soft actuator, which provides a solution for exploring the field of the soft robot. The problems of outer phenomenon and stress concentration are suppressed with pneumatic networks soft actuators.
Research on impact evaluation of academic journals from multidimensional perspective
Authors: Zhao Rongying , Wang Xu 
Published: August 2019

Purpose
The purpose of this paper is to introduce altmetric indicators and combine with traditional citation indicators to comprehensively evaluate the impact of academic journals from the perspective of multidimensional and multi-indicator fusion.

Design/methodology/approach
The authors take international multidisciplinary journals as an example, combining 14 traditional citation indicators of academic journals and introducing 14 altmetric indicators to build a comprehensive evaluation model of the impact of academic journals (academic impact and societal impact). At the same time, the authors systematically construct a journal evaluation indicator system from three dimensions. Then, the indicators data of three dimensions are evaluated by normalized processing, correlation analysis, reliability and validity analysis, PCA and factor analysis.

Findings
Two-dimensional and three-dimensional analyses can exactly provide some useful information for academic journals’ location in the respective coordinate systems. There are strong positive correlations among the measured indicators in the three dimensions, and each indicator has a significant consistency between whole and internal. The correlation coefficient between FD1 and FD2 is 0.888 with a strong positive correlation. It shows that the traditional citation indicators provided by WoS and Scopus database are highly consistent, and they are comparable and alternative in evaluating the academic impact of journals. The correlation coefficients of FD1, FD2 with FD3 are 0.831 and 0.798. There are strong positive correlations among them, which indicate that the evaluation of journals’ societal impact based on altmetrics indicator can be considered as a potential supplement to academic impact evaluation based on citation and to reflect the multidimensional nature of journals impact in an immediate way.

Originality/value
Multidimensional and multi-indicator perspective evaluation can provide references for the selection of impact evaluation indicators and model optimization of academic journals, and also provide new ideas for improving the status of the impact evaluation of academic journals.
Low frequency sound insulation performance of asymmetric coupled-membrane acoustic metamaterials
Authors: Cai Mengna , Tian Hongyan , Liu Haitao , Qie Yanhui 
Published: August 2019

Purpose
With the development of the modern technology and aerospace industry, the noise pollution is remarkably affecting people’s daily life and has been become a serious issue. Therefore, it is the most important task to develop efficient sound attenuation barriers, especially for the low-frequency audible range. However, low-frequency sound attenuation is usually difficult to achieve for the constraints of the conventional mass-density law of sound transmission. The traditional acoustic materials are reasonably effective at high frequency range. This paper aims to discuss this issue.

Design/methodology/approach
Membrane-type local resonant acoustic metamaterial is an ideal low-frequency sound insulation material for its structure is simple and lightweight. In this paper, the finite element method is used to study the low-frequency sound insulation performances of the coupled-membrane type acoustic metamaterial (CMAM). It consists of two identical tensioned circular membranes with fixed boundary. The upper membrane is decorated by a rigid platelet attached to the center. The sublayer membrane is attached with two weights, a central rigid platelet and a concentric ring with inner radius e. The influences of the distribution and number of the attached mass, also asymmetric structure on the acoustic attenuation characteristics of the CMAM, are discussed.

Findings
In this paper, the acoustic performance of asymmetric coupled-membrane metamaterial structure is discussed. The influences of mass number, the symmetric and asymmetry structure on the sound insulation performance are analyzed. It is shown that increasing the number of mass attached on membrane, structure exhibits low-frequency and multi-frequency acoustic insulation phenomenon. Compared with the symmetrical structure, asymmetric structure shows the characteristics of lightweight and multi-frequency sound insulation, and the sound insulation performance can be tuned by adjusting the distribution mode and location of mass blocks.

Originality/value
Membrane-type local resonant acoustic metamaterial is an ideal low-frequency sound insulation material for its structure is simple and lightweight. How to effectively broaden the acoustic attenuation band at low frequency is still a problem. But most of researchers focus on symmetric structures. In this study, the asymmetric coupled-membrane acoustic metamaterial structure is examined. It is demonstrated that the asymmetric structure has better sound insulation performances than symmetric structure.
Entrepreneurial learning: what do we mean by it?
Authors: Nogueira Tadeu Fernando 
Published: August 2019

Purpose
Given the growing recognition that learning plays a crucial role in entrepreneurship, this paper aims to systematically review the literature on entrepreneurial learning (EL), take account of its progress and analyze the unique characteristics of EL as a concept.

Design/methodology/approach
This paper uses a systematic approach to reviewing the literature on EL and critically assess the EL concept through the criteria of resonance, attributes (involving consistency, fecundity and differentiation), domain and causal utility.

Findings
A synthesis and assessment of extant literature reveals that a key challenge is the clear articulation of EL as a concept. This paper takes the first steps toward the specification of EL through a discussion of its unique properties. In this respect, the paper proposes the understanding of EL as an undertaking of entrepreneurial (i.e. proactive, exploratory and collaborative) learning behaviors (a crucial component of the EL concept) and recommends the context of new venture creation as an appropriate domain for the study of EL.

Research limitations/implications
This paper paves the way toward a more robust specification of EL as a concept.

Originality/value
This systematic literature review initiates a discussion about how EL literature can find convergence on key issues, thus helping the field move forward. It does so by articulating central attributes of the EL concept.

Published: August 2019

AbstractThe potential role of wild boars as a source of erysipelas infection was investigated. An ELISA test of wild boar serum samples from 41 prefectures in Japan revealed that proportions of the Erysipelothrix rhusiopathiae‐positive samples were very high in all the prefectures, and the mean positive rate was 95.6% (1312/1372). Serovars of E. rhusiopathiae isolates from wild boars were similar to those of previously reported swine isolates, and all serovar isolates tested were found to be pathogenic to mice. These results suggest that wild boars in Japan constitute a reservoir of E. rhusiopathiae and may pose risks to other animals.
Diversity, specificity and molecular evolution of the lytic arsenal of Pseudomonas phages: in silico perspective
Authors: Valero‐Rello Ana 
Published: August 2019

SummaryBacteriophages encode an arsenal of proteins to lyse bacteria by breaking their surface structures, constituting a promising alternative to antibiotics. However, the selection and bioengineering of endolysins and other phage lytic proteins need to be assisted by a previous knowledge of their molecular characteristics. In this study, all putative lytic proteins encoded in Pseudomonas phages were in silico examined to describe their diversity, host association and molecular evolution. A total of 491 proteins were identified among 223 phages, including endolysins, holins, pinholins, spanins, lipases and peptidases. Protein families and combination of functional domains were characteristic of phages belonging to the same genus, and these tended to infect a single host species. Clustering and phylogenetic analysis showed a protein grouping associated with bacterial host, and some functional domains being specific. Interestingly, most putative lytic proteins from phages infecting P. fluorescens and P. putida had negative net charges, opposed to most endolysins. Phage lifestyle also had an impact on protein variability, with transglycosylases, glucosaminidases, holins and spanins from lysogenic phages clustering into monophyletic nodes, suggesting the effect of a different selection pressure as a result of the co‐option of a new function in the lysogenized bacteria.

Published: August 2019

AbstractNurses are required to understand and meet the physiological needs of the family members of the patients hospitalized in transplant wards of the hospitals. Considering the importance of this issue, this study aimed to investigate the psychosocial needs of the families with an organ transplant patient. The study employed a cross‐sectional design and was conducted in Afzalipour Educational Hospital affiliated to the Kerman University of Medical Sciences in 2018. The 45‐item questionnaire of the psychosocial needs was applied to assess the psychosocial needs of the families with an organ transplant patient, including kidney, liver, and bone marrow. The quota sampling method was used and 230 participants completed the survey. Data were analyzed using descriptive mean and SD and analytical statistics independent t‐test, anova, and Pearson's correlation coefficient tests by SPSS 22 (version 22, SPSS, Chicago Inc., IL). The results indicated that the mean scores of psychological needs of families with transplanted patients hospitalized in three wards of bone marrow, kidney, and liver were at a high level (143/16 ± 12/29). The mean scores of psychosocial needs in the bone marrow transplantation ward (148/60 ± 8/18) were significantly higher than those of the patients hospitalized in the liver (141/24 ± 16/41) and kidney (141/25 ± 11/30) wards. A significant difference was observed among the three wards of the liver, kidney, and bone marrow transplantation with regard to the provided support, information, and proximity. To improve the psychological needs of the family members with patients hospitalized in transplant wards and reduce their mental reactions, they should be provided with more precise information about the patient's treatment procedure.

Abstract

Metabarcoding extra‐organismal DNA from environmental samples is now a key technique in aquatic biomonitoring and ecosystem health assessment. Of critical consideration when designing experiments, and especially so when developing community standards and legislative frameworks, is the choice of genetic marker and primer set. Mitochondrial cytochrome c oxidase subunit I (COI), the standard DNA barcode marker for animals, with its extensive reference library, taxonomic discriminatory power and predictable sequence variation, is the natural choice for many metabarcoding applications. However, for targeting specific taxonomic groups in environmental samples, the utility of COI has yet to be fully scrutinized.

Here, by using a case study of marine and freshwater fishes from the British Isles, we quantify the in silico performance of twelve primer pairs from four mitochondrial loci – COI, cytochrome b, 12S and 16S – in terms of reference library coverage, taxonomic discriminatory power and primer universality. We subsequently test in vitro four primer pairs – three COI and one 12S – for their specificity, reproducibility, and congruence with independent datasets derived from traditional survey methods at five estuarine and coastal sites around the English Channel and North Sea.

Our results show that for aqueous extra‐organismal DNA at low template concentrations, both metazoan‐targeted and fish‐targeted COI primers perform poorly in comparison to 12S, exhibiting low levels of reproducibility due to non‐specific amplification of prokaryotic and non‐target eukaryotic DNAs.

An ideal metabarcode would have an extensive reference library upon which custom primers could be designed, either for broad assessments of biodiversity, or taxon specific surveys. Such a database is available for COI, but low primer specificity hinders practical application, while conversely, 12S primers offer high specificity, but lack adequate references. The latter, however, can be mitigated by expanding the concept of DNA barcodes to include whole mitochondrial genomes generated by genome‐skimming existing tissue collections.

AbstractObjectivesNursing evaluations are an important component of residents’ professional development as nurses are present for interactions with patients and nonphysician providers. Despite this, there has been few prior studies on the benefits, harms, or effectiveness of using nursing evaluations to help guide emergency medicine residents’ development. We hypothesized that gender bias exists in nursing evaluations and that female residents, compared to their male counterparts, would receive more negative feedback on the perception of their interpersonal communication skills.MethodsData were drawn from nursing evaluations of residents between March 2013 and April 2016. All comments were coded if they contained words falling into four main categories: standout, ability, grindstone, and interpersonal. This methodology and the list of words that guided coding were based on the work of prior scholars. Names and gendered pronouns were obscured and each comment was manually reviewed and coded for valence (positive, neutral, negative) and strength (certain or tentative) by at least two members of the research team. Following the qualitative coding, quantitative analysis was performed to test for differences. To evaluate whether any measurable differences in ability between male and female residents existed, we compiled and compared American Board of Emergency Medicine in‐training examination scores and relevant milestone evaluations between female and male residents from the same period in which the residents were evaluated by nursing staff.ResultsOf 1,112 nursing evaluations, 30% contained comments. Chi‐square tests on the distribution of valence (positive, neutral, or negative) indicated statistically significant differences in ability and grindstone categories based on the gender of the resident. A total of 51% of ability comments about female residents were negative compared to 20% of those about male residents (χ2 = 11.83, p < 0.01). A total of 57% of grindstone comments about female residents were negative as opposed 24% of those about male residents (χ2 = 6.03, p < 0.01).ConclusionsOur findings demonstrate that, despite the lack of difference in ability or competence as measured by in‐service examination scores and milestone evaluations, nurses evaluate female residents lower in their abilities and work ethic compared to male residents.

Published: August 2019

AbstractAimThe aim of the study was to examine the effect of information placebo on fitness test results in normal weight, overweight and obese children.MethodsTwenty‐four pre‐pubertal children with overweight or obesity and 24 age and maturity‐matched normal weight children performed a progressive treadmill exercise test twice. Different types of information were randomly provided regarding a water drink consumed prior to testing; standard (water) vs deliberate positive (presumed energy drink, placebo) information.ResultsFollowing the placebo drink, both groups demonstrated significantly higher peak heart rate (overweight 165.8 ± 16.7 vs 174.2 ± 14.8 bpm and normal weight 177.9 ± 13.6 vs 189.8 ± 12.2 bpm) and longer time to exhaustion (overweight 396.9 ± 161.9 vs 521.5 ± 182.5 seconds; normal weight: 700.1 ± 155.2 vs 893.3 ± 150.1 seconds). Despite longer exercise duration and higher peak heart rate, average and peak rate of perceived exertion were significantly lower after the placebo drink (overweight 14.1 ± 2.5 vs 12.5 ± 2.5; normal weight 12.1 ± 1.4 vs 10.7 ± 1.5), with significantly shorter recovery time (overweight 132.2 ± 28.5 vs 118.4 ± 31.6; normal weight: 106.7 ± 18.6 vs 96.7 ± 17.8 seconds).ConclusionOur results demonstrate a significant effect of information placebo on fitness test results that is unrelated to body weight. Children with obesity may enhance their physical activity levels and energy expenditure if properly encouraged.

SummaryBackgroundMedication non‐adherence in paediatric ulcerative colitis (UC) has been associated with negative health outcomes including flares in disease activity. However, no studies to date have examined longitudinal adherence to maintenance medication in a prospective controlled trial.AimsTo determine whether objectively measured adherence to standardised mesalazine (mesalamine) therapy over time was related to remission at 52 weeks and the need for treatment escalation in newly diagnosed paediatric patients with UCMethodsPROTECT (NCT01536535) was a prospective, inception cohort, multi‐site study of paediatric patients aged 4‐17 years with newly diagnosed UC followed for 52 weeks. Patients received standardised mesalazine, with pre‐established criteria for escalation to thiopurines or anti‐TNFα inhibitors. Patients used pill bottles with electronic caps to monitor mesalazine adherence. We tested whether longitudinal adherence to mesalazine predicted steroid‐free remission at week 52 (i.e. quiescent disease on mesalazine alone with no corticosteroids ≥4 weeks prior) and need for treatment escalation (i.e. introduction of immunomodulators, calcineurin‐inhibitors or anti‐TNFα inhibitors).ResultsAmong 268 patients, average mesalazine adherence trajectories did not predict week 52 steroid‐free remission. Declining adherence over time strongly predicted treatment escalation (β = −.037, P = .001). By month 6, adherence rate ≤85.7% was associated with treatment escalation.ConclusionsNon‐adherence may have affected therapeutic efficacy of standardised mesalazine, thereby contributing to need for treatment escalation. Routine adherence monitoring for at least 6 months following treatment initiation and addressing adherence difficulties early in the disease course are recommended.
