Published: August 2019

AbstractMotivationReceptors on host cells play a critical role in viral infection. How phages select receptors is still unknown.ResultsHere, we manually curated a high-quality database named phageReceptor, including 355 pairs of phage-host receptor interactions, 280 unique viral species or sub-species and 64 bacterial species. Sugars and proteins were most widely used by phages as receptors. The receptor usage of phages in Gram-positive bacteria was different from that in Gram-negative bacteria. Most protein receptors were located on the outer membrane. The protein receptors were highly diverse in their structures, and had little homology with mammalian virus receptors. Further functional characterization of phage protein receptors in Escherichia coli showed that they had larger node degrees and betweennesses in the protein-protein interaction (PPI) network, and higher expression levels, than other outer membrane proteins, plasma membrane proteins, or other intracellular proteins. These findings were consistent with what observed for mammalian virus receptors, suggesting that viral protein receptors play a central role in the host’s PPI network. The study deepens our understanding of virus-host interactions.AvailabilityThe database of phageReceptor is publicly accessible at http://www.computationalbiology.cn/viralRecepetor/index.html.
Fractal-based triangular bandpass filter with a notched band for interference rejection in wideband applications
Authors: S. Karthie , S. Salivahanan 
Published: August 2019

Purpose
This paper aims to present the design of a novel triangular-shaped wideband microstrip bandpass filter implemented on a low-cost substrate with a notched band for interference rejection.

Design/methodology/approach
The conventional dual-stub filter is embedded with simple fractal-based triangular-circular geometries through various iterations to reject wireless local area network (WLAN) signals with a notched band at 5.8 GHz.

Findings
The filter covers a wide frequency band from 3.1 to 8.8 GHz and has a fractional bandwidth of 98 per cent with the lower passband of 57.5 per cent and upper passband of 31.6 per cent separated by a notched band at 5.8 GHz. The proposed wideband prototype bandpass filter is fabricated in FR-4 substrate using PCB technology and the simulation results are validated with measurement results which include insertion loss, return loss and group delay. The fabricated filter has a sharp rejection of 28.3 dB at 5.8 GHz. Measured results show good agreement with simulated responses. The performance of the fractal-based wideband filter is compared with other wideband bandpass filters.

Originality/value
In the proposed work, a fractal-based wideband bandpass filter with a notched band is reported. The conventional dual-stub filter is deployed with triangular-circular geometry to design a wideband filter with a notched band to suppress interference signals at WLAN frequency. The proposed wideband filter exhibits smaller size and better interference rejection compared to other wideband bandpass filter designs implemented on low-cost substrate reported in the literature. The aforementioned wideband filter finds application in wideband wireless communication systems.
Lump solutions and interaction phenomena of the (3 + 1)-dimensional nonlinear evolution equations
Authors: Mao Jin-Jin , Tian Shou-Fu , Yan Xing-Jie , Zhang Tian-Tian 
Published: August 2019

Purpose
The purpose of this study is to examine the lump solutions of the (3 + 1)-dimensional nonlinear evolution equations by considering a (3 + 1)-dimensional generalized Kadomtsev–Petviashvili (gKP) equation and a (3 + 1)-dimensional variable-coefficient generalized B-type Kadomtsev–Petviashvili (vcgBKP) equation as examples.

Design/methodology/approach
Based on Hirota’s bilinear theory, a direct method is used to examine the lump solutions of these two equations.

Findings
The complete non-elastic interaction solutions between a lump and a stripe are also discussed for the equations, which show that the lump solitons are swallowed by the stripe solitons.

Originality/value
The dynamics of these solutions are analyzed to enrich the diversity of the dynamics of high-dimensional KP-type nonlinear wave equations.

Rethinking indigenous climate governance through climate change and variability discourse by a Zimbabwean rural community
Authors: Mugambiwa Shingirai Stanley , Rukema Joseph Rudigi 
Published: August 2019

Purpose
The purpose of this paper is to assess indigenous climate governance through climate change and variability discourse by a rural Zimbabwean community. In Zimbabwe, climate governance has largely been presented from a political angle as indicated in the current climate governance structure. Apparently, the structure does not directly involve rural communities who at the same time suffer the most from the effects of climate change. Hence, the study intends to demonstrate that the manner in which humans perceive climate change influences their responses and actions vis-à-vis climate governance.

Design/methodology/approach
This qualitative study used 20 participants from a rural community in Zimbabwe. Their experiences were used as lances through which indigenous climate governance could be envisioned and executed. In-depth interviews were used to collect data and thematic content analysis was used to analyse data.

Findings
The study found that climate change perceptions and observations of weather conditions informs the community’s decisions on how to adapt to the impacts of climate change vis-à-vis indigenous knowledge systems (IKS) climate governance. The study also proposed a paradigm shift from a Western-oriented climate governance structure that currently exists in Zimbabwe to an indigenous model through a proposed IKS governance structure. This was considered significant because of the fact that it closely accommodates the community based on their lifestyle.

Originality/value
The study proposes a paradigm shift from a Western-oriented climate governance structure that currently exist in Zimbabwe to an indigenous model through a proposed IKS governance structure. This is arrived at by assessing climate change perceptions, narratives and experiences by community members. This is of particular importance because a few scholars have explored climate governance via IKS.
Healthcare providers’ images of refugees and their use of health services: an exploratory study
Authors: Van den Bos Nellie , Sabar Galia , Tenenboim Shiri 
Published: August 2019

Purpose
In 2017, the WHO presented a framework of priorities and guiding principles to promote the health of refugees and migrants (WHO, 2017). The purpose of this paper is to analyze a crucial but understudied aspect for the implementation of this framework, namely, healthcare providers’ images of refugees and their use of health services.

Design/methodology/approach
A preliminary study first addresses images of refugees and their use of health services derived from the literature. This is followed by an empirical case study of antenatal and delivery service to Eritrean refugee women in Israel. The case study explores providers’ (n=8) images of Eritrean women and their use of services as well as Eritrean women’s (n=10) reflections on their own use of these services, examining the degree to which providers’ images correspond with Eritrean women’s realities.

Findings
The preliminary study shows how the literature largely tends to picture refugees as medicalized and disempowered. The case study illustrates that providers of Israeli antenatal and delivery services embrace similar images, although they are more nuanced. The reflections of Eritrean women show that providers’ images partially reflect their realities. However, Eritrean women attribute these images to external constraints, whereas providers attribute these images to innate characteristics of Eritrean women. Together, these findings suggest that implementation of the recently introduced WHO framework is at stake.

Originality/value
This study raises awareness of a crucial but understudied aspect regarding implementation of a recently introduced universal framework for promoting the health of refugees and migrants.

Authors: Jiao Yuanyuan , Saeed Muhammad Aamir , Fu Shihui , Wang Xinyan 
Published: August 2019

Purpose
The purpose of this paper is to investigate the relationship between knowledge sharing and project portfolio success in Chinese construction firms. It also examines how and under what conditions knowledge sharing contributes to project portfolio success.

Design/methodology/approach
The authors collected questionnaire survey from 178 construction enterprises in China that manage project portfolio as a main form of their business. Hierarchical multiple regression was used to test the proposed framework.

Findings
The empirical results indicate that all three types of knowledge sharing (knowledge sharing within the project, knowledge sharing among projects and knowledge sharing within the organization) are positively related to project portfolio success. Portfolio management quality (PMQ) conduits the impact of knowledge sharing on project portfolio success. Furthermore, portfolio interdependency moderates the main effect.

Originality/value
This research is among the first to explicitly differentiate three types of knowledge sharing existing in project portfolios. Also, this research contributes to the literature on the antecedents of project portfolio success by showing the effect of knowledge sharing. Furthermore, this study empirically contributes to portfolio management research by clarifying the critical role of PMQ and portfolio interdependency in the mechanism of knowledge sharing and project portfolio success.

Authors: Chang Ching-Hung , Robinson Leigh , Shu Shih-Tung , Ma Shang-Chun 
Published: August 2019

Purpose
Customers’ innovativeness regarding services and products affects their purchase behavior. The purpose of this paper is to examine the moderation effect of fitness innovativeness (FI) (domain-specific innovativeness) and duration of stay on fitness customers’ revisit frequency.

Design/methodology/approach
This is a quantitative study. The purposive sampling survey method was used to obtain samples from the Taipei Nangang Fitness Center. Data were analyzed by moderated regression analysis.

Findings
The empirical results from 192 valid questionnaires that were obtained for data analysis revealed that FI has a positive impact on revisit frequency, and this impact is further increased if an individual is inclined to exercise and to stay longer at the fitness center.

Originality/value
A matrix of fitness innovator segments was developed to illustrate the research and managerial implications.
Comparative analysis of stearates as grease lubricant thickeners
Authors: Yao Lidan , Wang Lixin , Yang Haining , Li Chuan , Song Hui , Hu Xianguo 
Published: August 2019

Purpose
This paper aims to investigate the influence of stearate types on the thickening ability, dropping point and fiber structure of greases.

Design/methodology/approach
Several greases were prepared from polyolefins and various stearates. The melting point of the stearates and the dropping point of the resultant greases were measured, and the intermolecular binding energies of the thickener and the radial distribution function of the metal–oxygen in the thickener were determined with the aid of molecular simulation. The microstructures of the greases were also analyzed via scanning electron microscopy.

Findings
A higher stearate binding energy was found to correlate to a higher dropping point of the resultant greases. The thickening ability of the stearate is related to the group and period of the constituent metal ion. Within a group, greater atomic numbers of the metal were correlated to lower thickening ability. In a period, as the atomic number of the metal increased, the thickening ability was enhanced. The radial distribution functions of metal and oxygen can explain the aggregation of the stearate thickeners in the grease.

Originality/value
This work compared the thickening capacity of several stearates. Guidelines for preparing stearates to tailor the resultant grease are presented.
A numerical method to investigate the mixed lubrication performances of journal-thrust coupled bearings
Authors: Guo Xiang Guo Xiang , Han Yanfeng , Chen Renxiang , Jiaxu Wang Jiaxu Wang , Xiaokang Ni 
Published: August 2019

Purpose
This paper aims to present a numerical model to investigate the mixed lubrication performances of journal-thrust coupled bearings (or coupled bearings).

Design/methodology/approach
The coupled hydrodynamic effect (or coupled effect) between the journal and the thrust bearing is considered by ensuring the continuity of the hydrodynamic pressure and the flow field at the common boundary. The mixed lubrication performances of the coupled bearing are comparatively studied for the cases of considering and not considering coupled effect.

Findings
The simulated results show that the hydrodynamic pressure distributions for both the journal and thrust bearing are modified due to the coupled effect. The decreased load capacity of the journal bearing and the increased load capacity of the thrust bearing can be observed when the coupled effect is considered. And the coupled effect can facilitate in reducing the asperity contact load for both the journal and thrust bearing. Additionally, the interaction between the mixed lubrication behaviors, especially for the friction coefficient, of the journal and the thrust bearing is significant in the elastohydrodynamic lubrication regime, while it becomes weak in the mixed lubrication regime.

Originality/value
The developed model can reveal the mutual effects of the mixed lubrication behavior between the journal and the thrust bearing.
Integrating reciprocity into a social exchange model of inter-firm B2B relationships
Authors: Voss Kevin E. , Tanner Emily C. , Mohan Mayoor , Lee Yong-Ki , Kim Hong Keun 
Published: August 2019

Purpose
Reciprocity has traditionally been overlooked in social exchange models of inter-firm relationships. Therefore, this research integrates reciprocity and its antecedents into a social exchange model of inter-firm relationships.

Design/methodology/approach
The authors collected primary data from a sample of firms in the Republic of Korea using a questionnaire. They also used covariance-based structural equations modeling to fit the model given the proposed conceptualization.

Findings
Both conceptually and empirically, adding reciprocity and its antecedents to the social exchange model produce results that differ from previously published papers. Specifically, reciprocity affects information exchanged indirectly through both credibility and benevolence trust. In addition, the effect of information exchange mediates the effect of trust on calculative and affective commitment.

Research limitations/implications
The foundation of long-term inter-firm relationships is quality information exchange, which is based on the development of credibility and benevolence trust, which in turn is based on reciprocity. Thus, reciprocity is a key variable in relationship development.

Originality/value
To the best of the authors’ knowledge, this paper is among the first to combine reciprocity and its antecedents into a social exchange model that contains trust and commitment. This model provides a bigger picture of how firms develop long-term relationships with their partner firms.
Communicating role expectations in a coworking office
Authors: Walden Justin 
Published: August 2019

PurposeThe purpose of this paper is to understand the motivations behind teleworkers’ role transitions in a coworking office and how these motivations shape role communication between independent workers in a shared office.Design/methodology/approachThis paper draws upon observation, in-depth interviews (n=23) and temporary membership in the organization.FindingsSelf-enhancement and self-validation motivations work in concert to prompt individuals to capitalize on the networking opportunities that come with membership in this office and individuals strategically position an occupation-framed version of their identity in these networks.Research limitations/implicationsOnly one coworking office was studied. However, this is countered by the richness of the data.Practical implicationsCommunication managers whose organizations employ teleworkers are encouraged to provide ongoing social and task-related support to their teleworkers; coworking site proprietors are encouraged to ensure members understand what is expected of them when they join a coworking office.Social implicationsAs teleworking is a widely-used flexible work arrangement, this study advances knowledge of teleworker management.Originality/valueScholars have not yet explored how individuals use coworking spaces and what motivates teleworkers to establish their role identities in mixed offices.
An exploratory approach for enhancing vertical and horizontal equity tests forad valoremproperty tax valuations using geographically weighted regression
Authors: Bidanset Paul , McCord Michael , Davis Peadar , Sunderman Mark 
Published: August 2019

PurposeThe purpose of this study is to enhance the estimation of vertical and horizontal inequity within property valuation. Property taxation is a crucial source of finance for local government around the world – based on a presumptive tax base underpinned by estimates of property value, inaccurate real estate valuations used for suchad valoremor value-based property tax calculations potentially lead to a variety of costs, both financial and other, for tax payers and governments alike. More common are increased costs in time, staff and, in some cases, legal fees. Some governments are even bound by acceptability thresholds to promote fairness, equitability and overall government accountability with respect to valuation.Design/methodology/approachThere exist a number of vertical inequity measurements that have undergone academic testing and scrutiny within the property tax industry since the 1970s. While these approaches have proved successful in detecting horizontal and vertical inequity, one recurring disadvantage pertains to measurement error/omitted variable bias, stemming largely from a failure to accurately account for location. A natural progression within property tax research is the application of a more spatially local weighted modelling approach to examine vertical and horizontal inequity. This research, therefore, specifies a geographically weighted regression (GWR) methodology to detect and measure vertical inequity in property valuations.FindingsThe findings show the efficacy of using more applied spatial approaches for vertical tax estimation and indeed the limitations of employing conditional mean estimates coupled with delineated boundaries for assessing property tax inequity. The GWR model findings highlight the more fluctuating nature of vertical inequity across the Belfast market for the apartment sector both in a progressive and regressive sense and at different magnitudes. Moreover, the results reveal spatial clustering in the effects and are indicative of systematic inequities related to location inferring that spatial (horizontal) tax inequities are not random. The findings further show increased GWR model predictability overall.Originality/valueThis research adds to the existing literature base for evaluating both vertical and horizontal inequity in value-based property taxation at the intra-neighbourhood level. This is accomplished by modifying the Birch–Sunderman approach by transforming the traditional OLS model architecture to a GWR model, thereby allowing coefficient estimates of inequity to vary not only across a jurisdiction, but also at a more local level, while incorporating property characteristic variables. This arguably allows assessors to identify specific geographical areas of concern, saving them money, time and resources on identifying, addressing and correcting for inequity.
“Is this restaurant halal?” Surrogate indicators and Muslim behaviour
Authors: Khan Ghazala , Khan Faiza 
Published: August 2019

PurposeThe purpose of this study is to investigate what cues or surrogate indicators Muslims use to determine whether restaurants are suitable for dining purposes in the absence of the halal logo and to examine if the cues used are different among Muslims from non-Muslim countries as opposed to Muslims from Muslim countries.Design/methodology/approachData were collected via semi-structured interviews in one Muslim majority (Malaysia) and one non-Muslim country (the UK). A total of 16 adults participated in the study with an equal representation from both countries.FindingsIn the absence of the halal logo, participants relied on extrinsic cues such as the presence of other Muslim-looking customers and service personnel to determine whether a restaurant was deemed safe for dining in. The location of a restaurant was a strong indicator for Muslims in both Muslim and non-Muslim countries. In the absence of the halal logo, participants read the menus carefully, queried the service personnel for additional information and selected safer options, such as vegetarian and seafood.Research limitations/implicationsThe study used a small sample, and therefore, the findings are tentative.Practical implicationsGiven the growth of Muslim population in many non-Muslim countries, it is important for restaurants in non-Muslim countries not to marginalize this customer base. Trust is a key issue and service providers without the halal logo should gain the trust of Muslim customers by training service personnel and equipping them with knowledge of what halal means, developing menus with vegetarian and seafood options, providing detailed information on ingredients and communicating this on their websites and social media sites. They could also consider working with Muslim food and travel bloggers to promote themselves to a Muslim audience. They can develop a more Muslim sympathetic marketing approach and consider using separate cooking and serving utensils to gain trust and patronage of Muslim customers as well as to appeal to a larger market (vegans/vegetarians).Originality/valueThe present study is one of the first studies that concentrates on gaining an insight into how Muslims make decision pertaining to the selection and dining at a restaurant in the absence of the halal logo. A major contribution of the study is the identification of cues that assist Muslims when evaluating and selecting alternative food options in the absence of a halal logo.
