Published: October 2019

AbstractCockroaches are the most primitive insects, and are often used as the basic insect model in many studies. Three species ofPeriplanetacockroaches were raised in the laboratory for many generations under the same conditions. We conducted 16S rRNA-targeted high-throughput sequencing to evaluate the overall bacterial composition in the microbiomes of three species of cockroaches. The number of operational taxonomic units (OTUs) was not significantly different between the three cockroach species. With respect to the Shannon and Pielou indexes, the microbiome ofPeriplaneta americanapresented higher values than that of eitherP. japonicaorP. fulginosa. In terms of species composition, endosymbionts accounted for over half of all the bacterial species inP. japonicaandP. fulginosa. The beta diversity analysis showed thatP. japonicaandP. fulginosaexhibit a similar microbiome composition, which is different from that ofP. americana. However, we also identified thatP. japonicaandP. fulginosaare hosts to distinct bacterial species. Thus, although the composition of the microbiome may vary based on multiple conditions, it is possible to identify distinct compositions of the microbiome among the differentPeriplanetacockroach species even when individuals are reared under the same conditions.ImportanceCockroaches inhabit various habitats—which are known to be related to their microbiome—and exhibit different features depending on the species. It is expected that their microbiomes would vary according to species depending on these features. Cockroach microbiomes are known to vary based on the diet or environmental shifts. In this study, we compare the diversity of bacteria in the three cockroach species under conditions of reduced diet and environment shifts. This study can establish the basic microbiomes of threePeriplanetaspecies and can be the basic data for cockroach research.

AbstractThe central nervous system (CNS) is vulnerable for viral infection, yet few host factors in the CNS are known to defend invasion by neurotropic viruses. We report here that multiple neurotropic viruses, including rabies virus (RABV), vesicular stomatitis virus (VSV), Semliki Forest virus (SFV) and herpes simplex virus 1 (HSV-1), elicit the neuronal expression of a host-encoded lncRNA EDAL. EDAL inhibits the replication of these neurotropic viruses in neuronal cells and RABV infection in mouse brains. EDAL binds to the conserved histone methyltransferase enhancer of zest homolog 2 (EZH2) and specifically causes EZH2 degradation via lysosomes, reducing the cellular H3K27me3 level. The antiviral function of EDAL resides in a 56-nt antiviral substructure through which its 18-nt helix-loop intimately contacts multiple EZH2 sites surrounding T309, a known O-GlcNAcylation site. EDAL positively regulate the transcription of Pcp4l1 encoding a 10 kDa peptide, which inhibits the replication of mutiple neurotropic viruses. Our findings proposed a model in which a neuronal lncRNA can exert an effective antiviral function via blocking a specific O-GlcNAcylation that determines EZH2 lysosomal degradation.

Authors: Jiang Tingting , Guo Qian , Chen Shunchang , Yang Jiaqi 
Published: October 2019

PurposeThe headlines of online news are created carefully to influence audience news selection today. The purpose of this paper is to investigate the relationships between news headline presentation and users’ clicking behavior.Design/methodology/approachTwo types of unobtrusive data were collected and analyzed jointly for this purpose. A two-month server log file containing 39,990,200 clickstream records was obtained from an institutional news site. A clickstream data analysis was conducted at the footprint and movement levels, which extracted 98,016 clicks received by 7,120 headlines ever displayed on the homepage. Meanwhile, the presentation of these headlines was characterized from seven dimensions, i.e. position, format, text length, use of numbers, use of punctuation marks, recency and popularity, based on the layout and content crawled from the homepage.FindingsThis study identified a series of presentation characteristics that prompted users to click on the headlines, including placing them in the central T-shaped zones, using images, increasing text length properly for greater clarity, using visually distinctive punctuation marks, and providing recency and popularity indicators.Originality/valueThe findings have valuable implications for news providers in attracting clicks to their headlines. Also, the successful application of nonreactive methods has significant implications for future user studies in both information science and journalism.
Consumer preference for wine from hand-harvested grapes
Authors: Dominici Andrea , Boncinelli Fabio , Gerini Francesca , Marone Enrico 
Published: October 2019

Purpose
The purpose of this paper is to investigate preferences for wine made from hand-harvested grapes, and the interactive effect between this attribute and organic certification.

Design/methodology/approach
Data were collected via an online choice experiment involving a sample of 408 Italian wine consumers. A random parameter logit was performed to estimate consumer preferences for wine attributes: harvest type, organic and the interaction between these. The experiment also includes geographical indications and price. Furthermore, a latent class model (LCM) is performed to investigate taste heterogeneity for the included wine attributes.

Findings
On average, consumers prefer the wine produced with hand-harvested grapes. The hypothesis of an interaction between organic and hand-harvested attributes is rejected. Using the LCM, the authors identify three segments with significant taste heterogeneity in terms of the magnitude and the sign of the parameters. Moreover, consumer attitudes towards food naturalness differ according to their belonging to the segments.

Originality/value
The novelty of this article is twofold. First, this study investigates, for the first time, the impact of the hand-harvested method on consumer wine preferences. Second, hand-harvesting and organic have independent values.
Intentions to adopt safe food storage practices in older adults
Authors: Thaivalappil Abhinand , Papadopoulos Andrew , Young Ian 
Published: October 2019

Purpose
The purpose of this paper is to apply the theory of planned behaviour (TPB) to determine which psychosocial factors are predictors of older adults’ safe food storage practices at home.

Design/methodology/approach
An online structured questionnaire was developed and administered to older adults (60+). Two behavioural intention outcomes were investigated: thawing meats safely and storing leftovers within recommended guidelines. The survey instrument measured socio-demographic and TPB variables: attitudes, subjective norms, perceived behavioural control and intentions. A measure of self-reported habitual behaviour was also recorded and used to determine whether past practice influenced behavioural intentions.

Findings
Respondents (n=78) demonstrated good intentions to safely defrost meats and store leftovers. The models accounted for 41 and 48 per cent of the variance in intentions to perform safe storage behaviours. Attitudes and subjective norms were predictors of intentions to safely thaw meats. Habitual behaviour was a significant predictor of behavioural intentions to safely store leftovers. Perceived behavioural control was a significant predictor of intentions to thaw meats and store leftovers.

Research limitations/implications
The sample size was small, and results are to be interpreted with caution.

Practical implications
The results indicate that theory-based solutions to solving food safety among consumers may be a feasible strategy.

Originality/value
The study is the first of its kind to apply the TPB to this consumer group.
The global refugee crisis and the career ecosystem
Authors: Richardson Julia , Karam Charlotte M. , Afiouni Fida 
Published: October 2019

Purpose
The purpose of this paper is to introduce this special issue about the “Impact of the Global Refugee Crisis on the Career Ecosystem” and summarise the key contributions of the included practitioner and scholarly papers which examine refugee business and labour market experiences. The paper also examines the impact of media reports to provide a broader understanding of the context within which the current refugee crisis is evolving.

Design/methodology/approach
The authors begin with a delineation of the concept of a career ecosystem in the context of refugee crises. The authors then employ this framing as a backdrop to engage in a basic analysis of business media coverage of the most recent Syrian refugee crisis, and a summary of the practitioner and scholarly papers.

Findings
The findings of the media analysis suggest major coverage differences between different groups of countries in the number of documents identified, the proposed aim of business engagement with refugees, and substance of the extracted statements generally.

Research limitations/implications
The analysis of business media coverage is rudimentary and intended only as a prompt for further conversations about how contemporary media commentary impacts on career opportunities for refugees and relevant stakeholder practices.

Practical implications
This paper demonstrates the importance of including broader considerations of refugee careers that explore the interaction and intersection with transnational and local ecosystem of labour markets while paying attention to the sociocultural and political refugee-host community dynamics.

Originality/value
This paper presents a more systems-oriented perspective and provides both practice and scholarly perspectives on the composite and dynamic nature of the refugee crisis on career ecosystems more broadly.
The effects of attractiveness, gender and self-esteem in service jobs
Authors: Xu Shi , Martinez Larry , Smith Nicholas A. 
Published: October 2019

PurposeThe purpose of this paper is to investigate the impact of service providers’ attractiveness in service jobs and examine the underlying psychological mechanisms that may explain consumers’ different attitudes and potential behavior.Design/methodology/approachAn experimental design was used in this paper. Study 1 used a scenario depicting a front-desk agent performing check-in procedures and Study 2 used a scenario depicting a restaurant server. Data were analyzed using Hayes’ (2013) PROCESS macro.FindingsStudy 1 demonstrated the mediating effect of perceived interpersonal skills in the relations between front desk agent attractiveness and participant positive word-of-mouth and service satisfaction. Study 2 reaffirmed this finding and showed that the attractiveness of servers positively impacted participants’ perceptions of the servers’ interpersonal skill and participants’ tipping behavior. Furthermore, the relation between attractiveness and interpersonal skills was moderated by servers’ genders and participants’ levels of self-esteem, such that the effect was stronger in response to female servers for participants with relatively low self-esteem. In addition, the effect of the three-way interaction among server gender, server’s level of attractiveness, and participant’s level of self-esteem on tipping was mediated by participant’s perceived interpersonal skills.Originality/valueThis paper investigated the under-researched constructs of participants’ self-esteem and service providers’ gender and their moderating roles within the service context. These results suggest that responses to service providers can be impacted by the attractiveness and gender of the provider and customers’ self-esteems, despite equivalent objective performance of the provider.
Hospitality career retention: the role of contextual factors and thriving at work
Authors: Chang Wen , Busser James A. 
Published: October 2019

PurposeThis study aims to understand employee career retention in the hospitality industry. Building on the socially embedded model of thriving, signaling theory and social cognitive career theory (SCCT), the study examines a structural model of psychological contract fulfillment (PCF), perceived organizational support (POS), thriving, career satisfaction and career turnover intention.Design/methodology/approachThe proposed research model was tested using structural equation modeling with responses from 300 US hospitality employees. Data were collected using an online survey available through a panel service at Qualtrics.FindingsEmpirical results supported all proposed hypotheses and confirmed the critical mediation role of thriving for workplace contextual factors and employee career retention. As predicted, both PCF and POS positively influenced employee thriving, which positively influenced career satisfaction and negatively influenced career turnover intention.Practical implicationsFindings of this study yielded several recommendations for hospitality managers, including using the concept of thriving as an indicator and a remedy for employee career development and retention.Originality/valueGiven the increased need for qualified talent and reduced career satisfaction, this study sheds light on the further understanding of sustainable employment in the hospitality industry. Using signaling theory and SCCT as an overarching framework, this study extends the socially embedded model of thriving as well as SCCT and supports combining psychological contract theory and organizational support theory to better understand hospitality career retention.
Experimental research on compressive strength of UHPC spherical hinge
Authors: Jiawei Wang , Quansheng Sun 
Published: October 2019

Purpose
In order to reduce the impact of bridge construction on traffic under the bridge, the construction of bridges for some important traffic nodes usually adopts the swivel construction method. The spherical hinge is a rotating mechanism located between the bottom of the pier and the bridge cap, and is subjected to tremendous vertical pressure. According to the mechanical characteristics of the spherical hinges, this paper applies the ultra-high performance concrete (UHPC) material to the spherical hinge. The spherical hinge is subjected to a compression test to test its mechanical behavior. This paper aims to discuss this issue.

Design/methodology/approach
In order to test the mechanical behavior of the UHPC spherical hinge, multiple sets of 100 mm UHPC spherical hinge specimens were prefabricated. Through the universal testing machine to measure the compressive strength of specimens, draw the force-displacement curve to analyze the failure mechanism and establish the stress calculation formula of the spherical hinge at each point along the radial direction.

Findings
Through the test, the compressive strength of UHPC spherical hinge is obtained, and the influencing factors of UHPC spherical hinge strength are found: reducing water–cement ratio, increasing steel fiber content and length and changing steel fiber arrangement direction can effectively improve the compression strength of UHPC spherical hinge.

Originality/value
For the first time, UHPC materials were applied to the spherical hinge structure, the UHPC spherical hinge diameter is 1/3 of the diameter of the reinforced concrete spherical hinge, which is equivalent to the diameter of the steel spherical hinge. By applying the UHPC spherical hinge, the manufacturing cost is reduced, the process is simple, and the construction difficulty is reduced.
Pseudo-static test research on EBIMFCW with different shear-span ratio
Authors: Li Sheng-cai , Lin Guo 
Published: October 2019

Purpose
The purpose of this paper is to study the seismic performance of the energy-saving block and invisible multi-ribbed frame composite walls (EBIMFCW), changing the shear-span ratio as the test parameter, the low-cycle reciprocating loading tests of six 1/2 scale wall models were carried out.

Design/methodology/approach
The test design method and analysis are used for the seismic performance of the EBIMFCW.

Findings
With the increase of shear-span ratio: the walls tend to occur bending failure even more, the initial stiffness of the wall decreases, the overall ductility of the wall is improved and the walls tend to occur bending failure.

Originality/value
The previous studies do not involve the seismic performance of EBIMFCW under different shear-span ratios. Therefore, the paper studies the hysteresis behavior, ductility, stiffness degradation and energy dissipation performance of EBIMFCW under different shear-span ratios.
Pricing of property valuation services in Lagos Nigeria
Authors: Oladokun Sunday Olarinre , Mooya Manya Mainza 
Published: October 2019

Purpose
The pricing of professional service has been identified as one of the factors influencing the quality of service and willingness of clients to pay. However, the issue of service pricing is hardly seen as an object of discourse in real estate literature, especially among valuation studies, as it is obtainable in other fields. In Nigeria, it has become the practice for some sets of clients, especially financial institutions, to fix valuers’ remuneration based on the fact that these clients have market advantage. This practice and some other issues around pricing of valuers’ services have been going on for some years with little or no research insights from academics. The purpose of this paper is to examine the pricing system of valuation services within the Lagos property market with the aim of providing information to better valuation practice.

Design/methodology/approach
This study assumes an interpretive paradigm and adopts a qualitative research approach. In-depth semi-structured interviews were conducted with 24 registered valuers practising within the Lagos property market. Snowballing sampling technique was employed in selecting the registered valuers who were active in the practice of valuation in the study area. Data collected were analysed using thematic analysis with the aid of NVivo 12 software.

Findings
This study finds that the pricing system for valuation services in the study area can be broadly categorised under “negotiation” and “fixed rate” systems while the use of the “professional scale of charges” is more or less non-existent. The study also reveals various forms by which these systems are practised, and issues associated with them as well as the effects they have on valuation practice. The study further reveals the factors responsible for the continuous striving of the present pricing system which includes valuers’ inability to enforce the professional scale, competition in the market, buyers’ market syndrome, the game of numbers and the banks’ strategy to protect their customers. The authors also found that the low pricing of valuation service poses challenges to valuation practice and encourages unprofessional conducts that affect the quality of valuation output. The study also provides, albeit limited, an evidence of the relationship between valuation fee and quality of valuation.

Research limitations/implications
This study is limited to Lagos property market and only the practising valuers. Insights from other major cities and stakeholders in service pricing like clients and regulatory authority may produce more insightful results.

Originality/value
This study provides important insights into valuers’ experience in the area of service pricing and how this affects the delivery of professional services. It also serves as the research blueprint in giving research attention to the service pricing in property valuation practice.
Zooming in on the workplace bullying and turnover intentions pathway
Authors: Ahmad Saima , Kaleem Ahmad 
Published: October 2019

PurposeDespite the well-established association between workplace bullying and turnover intentions, the mechanisms underlying this relationship and its boundary conditions remain understudied. The purpose of this paper is to examine employee affective well-being as a mediating mechanism by which exposure to workplace bullying may trigger employee intentions to leave the workplace. It also aims to explore the role of national culture in moderating the effects of workplace bullying on employee well-being and turnover intentions.Design/methodology/approachThis research is conducted through a cross-cultural analysis of data obtained from 627 Australian and Pakistani employees.FindingsThe findings reveal that exposure to workplace bullying triggers turnover intentions through its negative effect on affective well-being in cross-cultural/national contexts. However, national culture moderates these effects such that the effects of workplace bullying on well-being and turnover intentions are weaker for Pakistanis than for Australians.Originality/valueThis paper reports original research that deepens the understanding of how, why and when exposure to workplace bullying will prompt employees to leave the workplace in a cross-national context. The research findings will assist international organisations in designing strategies tailored to the national culture in order to mitigate the adverse effects of workplace bullying on staff turnover.
Rock physics modelling of porous rocks with multiple pore types: a multiple‐porosity variable critical porosity model
Authors: Zhang Jiajia , Yin Yingyao , Zhang Guangzhi 
Published: October 2019

ABSTRACTA critical porosity model establishes the empirical relationship between a grain matrix and a dry rock by the concept of critical porosity. The model is simple and practical and widely used. But the critical porosity in the model is a fixed value that cannot relate to pore structure. The aim of this paper is to establish the theoretical relationship between critical porosity and pore structure by combining Kuster–Toksöz theory with the critical porosity model. Different from the traditional critical porosity model, critical porosity is not an empirical value but varied with pore shape and the ratio of bulk modulus versus shear modulus of the grain matrix. The substitution of the theoretical relationship into Kuster–Toksöz theory will generate the formulae for the bulk and shear moduli of multiple‐porosity dry rocks, which is named the multiple‐porosity variable critical porosity model. The new model has been used to predict elastic moduli for sandstone and carbonate rock. We compare the modelling results for P‐ and S‐wave velocities and elastic moduli with the experimental data. The comparison shows that the new model can be used to describe the elastic properties for the rocks with multiple pore types.
