Role of Membrane-tension Gated Ca Flux in Cell Mechanosensation
Authors: He Lijuan , Tao Jiaxiang , Si Fangwei , Wu Yi , Wu Tiffany , Prasath Vishnu , Wirtz Denis , Sun Sean X. 
Published: May 2017

AbstractEukaryotic cells are sensitive to mechanical forces that they experience from the environment. The process of mechanosensation is complex, and involves elements such as the cytoskeleton and active contraction from myosin motors. Ultimately, mechanosensation is connected to changes in gene expression in the cell, or mechanotransduction. While the involvement of the cytoskeleton in mechanosensation is known, processes upstream to cytoskeletal changes is unclear. In this paper, using a microfluidic device that mechanically compresses live cells, we demonstrate that calcium currents and membrane tension-sensitive ion channels directly signals to the Rho GTPase and myosin contraction. In response to membrane tension changes, cell actively regulates cortical myosin contraction to balance external forces. The process is captured by a mechanochemical model where membrane tension, myosin contraction and the osmotic pressure difference between the cytoplasm and extracellular environment are connected by mechanical force-balance. Finally, to complete the picture of mechanotransduction, we find that the tension-sensitive transcription factor YAP translocates from the nucleus to the cytoplasm in response to mechanical compression.
Evaluation of citations: a proposition to supplement the corresponding rule book in Serbia
Authors: Dimic Surla Bojana , Surla Dusan Ilija , Ivanovic Dragan 
Published: May 2017

Purpose
The purpose of this article is to describe a proposition for the evaluation of citations of scientific papers, which could serve as a supplement to the existing Rule Book of the Ministry of the Republic of Serbia, which is used in the procedure of electing candidates for particular academic and research titles. The evaluation and quantitative presentation of the results and evaluation of citations were carried out on data taken from the database of the Current Research Information System of the University of Novi Sad (CRIS UNS), which is harmonized with the Rule Book of the Ministry with respect to the evaluation of published scientific results of researchers.

Design/methodology/approach
There are different criteria to evaluate the quality of scientific papers based on their citations. The pertinent parameters can be the total number of citations, the number of citations in a defined time period and by assigning the appropriate weighting values to the citations. This work proposes a procedure of assigning the citation weighting values based on the evaluation of the scientific results in which the citation appeared according to the Rule Book in the Republic of Serbia. Based on this, the authors introduced the impact factor of researchers as the ratio of the number of points of the evaluated citations and the number of points of the evaluated papers of the researcher.

Findings
Results showed that the research information system CRIS UNS can be extended to the evaluation of citations for a single researcher, groups of researchers and institutions.

Practical implications
The proposed solution enables the evaluation of citations in the process of election and promotion of academic staff. In this way, there is a means for measuring the scientific influence of a researcher in the relevant scientific area.

Social implications
The evaluation of citations may be included in the national strategies of scientific development, funding and evaluation of research projects; for promotions of academic staff at the universities and other academic institutions; and ranking of researchers and research organizations.

Originality/value
The main idea presented in the paper is the definition of a rule book (or several rule books) for the evaluation of citations. Based on the evaluation of citations, the authors proposed the term “the impact factor of researcher”.
Does gender make a difference in business performance?
Authors: Ali Jabir , Shabir Sana 
Published: May 2017

Purpose
This paper aims toanalyse the difference in business performance and obstacles across male-owned versus female-owned enterprises in India.

Design/methodology/approach
This study is based on a comprehensive enterprise survey of 9,281 Indian firms operating in different regions of the country, conducted under the World Bank’s Enterprise Survey, 2014. The survey contains information on a variety of enterprise characteristics such as ownership, type of firms, size of firms, locations and age, performance indicators and information on 16 parameters of business obstacles. Business performance indicators have been derived from data in the form of growth in sales, employment, labour productivity and capability utilization by gender ownership of the firms. Simple statistical tools such as descriptive statistics, chi-square test and the independent-samples t-test have been used to analyse the data. Further, an ordered probit regression model has been estimated to identify the relative importance of parameters affecting female-owned enterprises.

Findings
Of the total 9,281 firms surveyed under the World Bank’s Enterprise Survey, about 8 per cent were being managed by a top female manager and about 15 per cent firms reported to have at least one female owner. Among the female owners, about 36 per cent were reported to own 50 per cent and above share of the firm. Chi-square statistics indicate that there is a significant difference in enterprise characteristics of male- versus female-owned firms in terms of location, size, type and age. Result of the independent-samples t-test indicates a significant difference in business performance across male- and female-owned businesses in terms of annual sales growth, labour productivity growth and capacity utilization of the firms. Similarly, the perception of male- and female-owned firms significantly vary on 10 obstacles out of total 16 business obstacle parameters. Overall, females perceive comparatively less business obstacles as compared to males. An ordered probit regression model has revealed the relative importance of enterprise characteristics, performance indicators and extent of business obstacles among female-owned enterprises.

Practical implications
This study provides an insight on the differences in the firms’ performance across gender ownership based on a large survey data. This study can be helpful in designing policies for promoting gender-based business enterprises in a focused manner.

Originality/value
There are limited empirical evidences on difference in organizational profile, business performance and understanding business obstacles across male- versus female-owned firms in India based on a large survey data.
The power of self-service technologies in creating transcendent service experiences
Authors: Wei Wei , Torres Edwin N. , Hua Nan 
Published: May 2017

PurposeThe purpose of this paper is to draw upon the theory of consumption values and the experiential value scale to develop a conceptual model concerning hospitality customer’s use of self-service technologies (SSTs) and their impact on consumers’ service experience.Design/methodology/approachQuestionnaires were administered to 220 hotel and restaurant customers. The researchers tested the hypotheses by using descriptive analysis, confirmatory factor analysis and path analysis.FindingsBoth extrinsic and intrinsic attributes of SSTs influence consumers’ satisfaction with SST usage significantly, while the extrinsic attributes play a stronger role. It is worth noting that while the intrinsic attributes have a significant impact on consumers’ transcendent service experience, the extrinsic attributes negatively influence such experience.Practical implicationsThe findings help managers create effective strategies to better match consumers’ needs and to deliver more customized self-service experience. The role of SSTs can be expanded beyond functional attributes to satisfy consumers’ curiosity, foster customer–customer interactions and personalize consumer experience.Originality/valueAlthough most SSTs research focus on technology adoption intention, features, functionality and benefits to the service provider, this research is among the first attempts to examine the role of SSTs in creating better consumer experience. The bidimensional conceptualization of SSTs experience developed in this research suggests that SSTs in the hotel and restaurant sector should be utilized for reasons beyond their utilitarian attributes: SSTs should be designed to help create a transcendent service experience.
A new demountable seismic-resistant joint to improve industrial building reparability
Authors: Pongiglione Margherita , Calderini Chiara , Guy George Bradley 
Published: May 2017

PurposeIn seismic-prone areas, post-event operability is an important issue for steel warehouses. Even if surviving earthquakes with minimal probability of collapse, these structures might suffer so much damage, that their repair costs would be prohibitive. Strategies for limiting the building's damaged zones to specific parts (or “fuses”) can reduce repair costs. However, the replaceable part is limited to a small portion of the structure, whereas the rest cannot be disassembled. This is an issue for structures whose life span depends more likely on economics rather than on structural performances. Therefore, making them easily disassembled would be an advantage not only in seismic areas but also in any industrialized area. The purpose of this paper is to explore the “Design for Disassembly” (DfD) approach to complement seismic design and find a compromise between them.
Design/methodology/approachIn this work, one single type of structures was analysed (the moment-resisting frame), focusing on the design of a “disassemblable” seismic-resistant steel connection. The design process involved several iterations until an “optimum” compromise between seismic design and DfD was met.
FindingsThis study shows that a compromise between seismic design and DfD is possible. In this case, the compromise was achieved at the expenses of more complex design calculations and a greater number of components than standard connections. However, this would be compensated for by a higher residual value for the entire structure.
Originality/valueEventually, it was proved that a metric for assessing DfD steel connections is possible, but structural analyses are needed to validate it.
Trade policy and health implication for Pacific island countries
Authors: ‘Ofa Siope Vakataki , Gani Azmat 
Published: May 2017

Purpose
The purpose of this paper is to examine the effect of trade policy pertaining to imported processed food on poorer health outcomes of people’s in the Pacific island countries.

Design/methodology/approach
Using an extended gravity model, the paper adopts the OLS time varying importer/exporter effects method and a Pseudo Poisson maximum likelihood estimator on a cross-sectional panel data set of 215 countries and territories. The estimation procedure controlled for 11 Pacific island countries between 2003 and 2013.

Findings
The empirical findings revealed a positive and statistically significant relationship between trade liberalisation and increased processed food imports in the Pacific island countries. The findings also reveal that the access ratio (kg/person) to selected imported processed food high in salt to Pacific island countries has increased significantly over time.

Originality/value
While much of the trade literature reveals positive impact of trade on the prosperity of nations, this study makes a new contribution in terms of supporting a negative impact of trade liberalisation policy on people’s health in small island developing states.
Friction and wear behavior of hydrogenated diamond-like carbon coating against titanium alloys under large normal load and variable velocity
Authors: Liu Jun , Zhang Zhinan , Ji Zhe , Xie Youbai 
Published: May 2017

Purpose
This paper aims to investigate the effects of reciprocating frequency, large normal load on friction and wear behavior of hydrogenated diamond-like carbon (H-DLC) coating against Ti-6Al-4V ball under dry and lubricated conditions.

Design/methodology/approach
The friction and wear mechanisms are analyzed by scanning electron microscope, energy dispersive spectroscopy and Raman spectroscopy.

Findings
The results show that as reciprocating frequency increases under lubricated conditions, the friction coefficient decreases first and then increases. When the reciprocating frequency is 2.54 Hz, the value of friction coefficient reaches the minimum. The friction reduction is because of the transformation from sp3 to sp2, the formation of transfer layer on Ti-6Al-4V ball and the reduction in viscous friction, whereas the increase of friction coefficient is related to wear. In dry conditions, the friction coefficient is between 0.06 and 0.1. And, the service life of H-DLC coating decreases with the increase in reciprocating frequency and normal load.

Research limitations/implications
It is confirmed that adding the lubricant could prolong the service life of H-DLC coating and reduce friction and wear efficiently. And, the wear mechanisms under dry and lubricated conditions encompass abrasive wear and adhesive wear.

Originality/value
The results are helpful for application of diamond-like carbon coating.
Affirmative action policy in admissions system of higher education of post-Soviet Georgia
Authors: Tabatadze Shalva , Gorgadze Natia 
Published: May 2017

Purpose
The purpose of this paper is to explore affirmative action policy in higher education (HE) admissions in post-Soviet Georgia.

Design/methodology/approach
The study analyzed the effectiveness of the quota system from the perspective of the “minority rights protection” and “diversity” paradigms. The study used content analysis, focus group discussions, and interviews research methods.

Findings
Research revealed several important patterns: the problems of minority education are associated with academic achievements as well as social integration; although the importance of diversity is evident in the Government of Georgia, the benefits of diversity are not realized fully through affirmative action policies in institutions of HE. The authors have argued that the shift from the “minority rights protection” to the “diversity” paradigm is necessary to solve minority students’ existing problems and to benefit from the positive effects of diversity on academic and democratic outcomes for all students.

Practical implications
The findings of this study have practical importance. They can be used for the implementation of the affirmative action policy in HE admissions system of Georgia.

Originality/value
The paper is based on original research conducted in Georgia and the study contributes to the development of the field of multicultural and minority education in Georgia.
Team political skill and team performance
Authors: Semrau Thorsten , Steigenberger Norbert , Wilhelm Hendrik 
Published: May 2017

PurposeThe purpose of this paper is to examine the relation between team political skill, i.e., the mean level of political skill among team members, and team performance. Specifically, it proposes that the link between team political skill and team performance is ambiguous and contingent upon a common professional background as well as collective team commitment within the team.Design/methodology/approachData from 45 service teams with 295 team members and their supervisors were analyzed. Hypotheses were tested using OLS regression.FindingsThe results show that a common professional background and collective team commitment serve as crucial contingencies for the relationship between team political skill and team performance.Research limitations/implicationsThis study complements previous individual-level research demonstrating a positive relation between political skill and relevant outcomes by highlighting that the link between team political skill and team performance is ambiguous and contingent upon other team characteristics.Practical implicationsTo enhance team performance, managers should carefully consider the interplay between team political skill and other team characteristics when making staffing decisions.Originality/valueThe study highlights the relation of political skill with team performance and points to a potential downside of political skill in organizations.
Social change design: disrupting the benchmark template
Authors: Fry Marie-Louise , Previte Josephine , Brennan Linda 
Published: May 2017

Purpose
This paper aims to propose a new ecological systems-driven framework, underpinned by a relational marketplace lens, for social marketing practitioners to consider when planning and designing programs. The authors contend that behavioural change does not occur in a vacuum and, as such, point to an ecology in which the individual is but one participant in a broader scope of social change activities.

Design/methodology/approach
The paper is conceptual and presents the Indicators for Social Change Framework.

Findings
The Indicators for Social Change Framework puts forward a series of “must-have” indicators to consider when designing and planning social marketing programmes. Across identified indicators, the Framework delineates types of marketing actions to consider when planning for individual-oriented change and those required for wider systems-oriented change.

Originality/value
This paper contributes to the broadening and deepening of the social marketing argument that reliance on individual behaviour change perspectives is not sufficient to resolve complex social problems that are inherently influenced by wider social forces. In transforming social change design, this paper transitions towards a logic view of social marketing that encourages and supports social change planners to be inclusive of interactions, processes and outcomes of value creation across the wider social marketing system.
A fiber-reinforced thermoelastic medium with an internal heat source due to hydrostatic initial stress and gravity for the three-phase-lag model
Authors: Said Samia M. 
Published: May 2017

Purpose
The purpose of this paper is to investigate the effect of a hydrostatic initial stress and the gravity field on a fiber-reinforced thermoelastic medium with an internal heat source that is moving with a constant speed.

Design/methodology/approach
A general model of the equations of the formulation in the context of the three-phase-lag model and Green-Naghdi theory without energy dissipation.

Findings
The exact expressions for the displacement components, force stresses, and the thermal temperature for the thermal shock problem obtained by using normal mode analysis.

Originality/value
A comparison made between the results of the two models for different values of a hydrostatic initial stress as well as an internal heat source. Comparisons also made with the results of the two models in the absence and presence of the gravity field as well as the reinforcement.

Published: May 2017

AbstractObjectivesEvidence suggests that, despite routine engagement with the health system, pregnant women commonly seek emergency care. The objectives of this study were to examine the association between maternal comorbidities and emergency department (ED) use among a national sample of commercially insured pregnant women.MethodsWe conducted a retrospective cohort study using multipayer medical claims data maintained by the Health Care Cost Institute for women ages 18 to 44 years with a live singleton birth in 2011 (N = 157,786). The association between common maternal comorbidities (e.g., hypertension, gestational diabetes) and ED use during pregnancy was examined using multilevel models, while controlling for age, region, and residential zip code.ResultsTwenty percent (n = 31,413) of pregnant women had one or more ED visit (mean ± SD = 1.52 ± 1.15). Among those who used the ED, 29% had two or more visits, and 11% had three or more visits. Emergency care seekers were significantly more likely to have one or more comorbid condition compared to those with no emergency care: 30% versus 21%, respectively (p < 0.001). Pregnant women with asthma had 2.5 times the likelihood of having had any ED visit (adjusted odds ratio [AOR] = 2.46, 95% confidence interval [CI] = 2.32–2.62). There was a significant increase in the probability (approximately 50%) of ED use among pregnant women with diabetes (AOR = 1.47, 95% CI = 1.33–1.63) or hypertension (AOR = 1.49, 95% CI = 1.43–1.55) or who were obese (AOR = 1.55, 95% CI = 1.47–1.64). Increased odds associated with gestational diabetes were more modest, resulting in a 13% increased odds of using the ED (AOR = 1.13, 95% CI = 1.07–1.18). Less than 0.6% of pregnant women (n = 177) received emergency care that resulted in a hospital admission. The admission rate was 0.4% (189 admissions/47,608 ED visits).ConclusionsAmong pregnant women, comorbidity burden was associated with more ED utilization. Efforts to reduce acute unscheduled care and improve care coordination during pregnancy should target interventions to patient comorbidity.
But I'm Just an Artist!? Intersections, Identity, Meaning, and Context
Authors: Luger Jason D. 
Published: May 2017

AbstractThis article revisits the complex intersections of identity and meaning in the context of a world in which cosmopolitanism is increasingly questioned. The role of the artist with regard to activism and cosmopolitan flows becomes difficult to navigate but important to probe. Findings drawn from fieldwork indicate that the artist is highly conflicted; often ephemerally aligned with various social movements that may or may not be related; and in a constant state of self‐negotiation and identity formation that are highly dependent on local context. Intersectionality may be a useful frame to reconceptualize the artist as a relationally connected set of constantly shifting identities rather than an assumed category, as sometimes portrayed. Key to this is an appreciation of the role of the observer in this process. Singapore is envisioned as a place of intersecting identity; so, too, are the artists within it, caught between local context and global currents.

AIMThe aim of the present study was to evaluate the effect of the proposed organic cation transporter (OCT) inhibitor daclatasvir on the pharmacokinetics and pharmacodynamics of the OCT substrate metformin.METHODSThis was an open‐label, two‐period, randomized, crossover trial in 20 healthy subjects. Treatment A consisted of metformin and treatment B consisted of metformin + daclatasvir. Pharmacokinetic curves were recorded at steady‐state. Geometric mean ratios (GMRs) with 90% confidence intervals (CIs) were calculated for metformin area under the concentration–time curve from 0 h to 12 h (AUC0–12), maximum plasma concentration (Cmax) and final plasma concentration (Clast). An oral glucose tolerance test was performed, measuring insulin, glucose and lactate levels.RESULTSThe GMRs (90% CI) of metformin AUC0–12, Cmax and Clast (B vs. A) were 109% (102–116%), 108% (101–116%) and 112% (103–122%). The geometric mean AUC0–2 for insulin, glucose and lactate during treatments A and B were 84 h.mEl–1 and 90 h.mEl–1, 13.6 h.mmol l–1 and 13.4 h.mmol l–1, and 3.4 h.mmol l–1 and 3.5 h.mmol l–1, respectively.CONCLUSIONSBioequivalence analysis showed that daclatasvir does not influence the pharmacokinetics of metformin in healthy subjects. Pharmacodynamic parameters were also comparable between treatments.
