Published: October 2018

AbstractObjectivesThe purpose of our research was to examine the effects of Minocycline combined hyaluronic acid (HA)-mediated Ultrasound therapy of infected wound in wister rats.Methods40 female wister rats were made wound on the two side of the backbone, then infected in Staphylococcus aureus at the comic for three times. then, they are divided into four groups: control group, minocycline combined HA alone, ultasound alone, minocycline combined HA-mediated ultasound group, respective. After 3 times of treatments, the rats were killed and made into specimens. Assessments consisted of visual inspection in the change of the skin, scar formation pathological morphology by hematoxylin and eosin(HE) stain with optical microscopy, IL-1B assaying and TNF-a were performed.ResultCompared with control group, minocycline combined HA alone, ultasound alone, minocycline combined HA-mediated ultasound group all have effect for wound healing, there was a obvious improvement in all parameters over the duration of the experiment(P<0.05). Compared with the control group, minocycline combined HA-mediated ultasound group indicated less inflammation cells (P<0.001) and the reduce of and IL-1B and TNF-a (P<0.001).ConclusionMinocycline combined HA-mediated ultrasound can accelerate tissue regrowth, which exert significant benefits in healing the wounds.
150 years of research on Vierordt’s law - Fechner’s fault?
Authors: Glasauer Stefan , Shi Zhuanghua 
Published: October 2018

Abstract150 years ago, the physiologist Karl Vierordt discovered one type of systematic errors in time perception – an overestimation of long durations and underestimation of short durations, now known as Vierordt’s law. Here we review the original study in its historical context and ask whether Vierordt’s law is a result of an unnatural experimental randomization protocol. Using iterative Bayesian updating, we simulated the original results with astonishing accuracy. To validate whether the experimental protocol matters, we compared duration reproduction from two sequences with the same sampled distribution and found that trial-wise variation determines the reproduction error. We conclude that Vierordt’s law is caused by an unnatural yet widely used experimental protocol.One Sentence SummaryProbabilistic modeling reveals that a classical perceptual error - Vierordt’s law - is caused by an unnatural yet widely used experimental protocol.
Sequential digestion with Trypsin and Elastase in cross-linking/mass spectrometry
Authors: Dau Therese , Gupta Kapil , Berger Imre , Rappsilber Juri 
Published: October 2018

ABSTRACTCross-linking/mass spectrometry has become an important approach for studying protein structures and protein-protein interactions. The amino acid composition of some protein regions impedes the detection of cross-linked residues, although it would yield invaluable information for protein modelling. Here, we report on a sequential digestion strategy with trypsin and elastase to penetrate regions with a low density of trypsin cleavage sites. We exploited intrinsic substrate recognition properties of elastase to specifically target larger tryptic peptides. Our application of this protocol to the TAF4-12 complex allowed us to identify cross-links in previously inaccessible regions.
Distinctions and boundaries: men’s talk about food celebrities
Authors: Neuman Nicklas , Gottzén Lucas , Fjellström Christina 
Published: October 2018

PurposeThe purpose of this paper is to explore how a group of men relate to food celebrities in the contemporary Swedish food-media landscape, especially celebrity chefs on TV.Design/methodology/approachSemi-structured interviews were conducted with 31 men in Sweden (22–88 years of age), with different backgrounds and with a variety of interest in food.FindingsThe paper demonstrates different ways in which the men relate to food celebrities. The men produce cultural distinctions of taste and symbolic boundaries, primarily related to gender and age, but also class. Through this, a specific position of “just right” emerged. This position is about aversion to excess, such as exaggerated gendered performances or pretentious forms of cooking. One individual plays a particularly central role in the stories: Actor and Celebrity Chef Per Morberg. He comes across as a complex cultural figure: a symbol of slobbish and tasteless cooking and a symbol of excess. At the same time, he is mentioned as the sole example of the exact opposite – as a celebrity chef who represents authenticity.Practical implicationsScholars and policy makers must be careful of assuming culinary or social influence on consumers from food celebrities simply based on their media representations. As shown here and in similar studies, people relate to them and interpret their performances in a variety of ways.Originality/valueThis is one of the few studies that target the role of food celebrities in contemporary Western consumer culture from the point of view of the consumers rather than analyses of media representations.
Critical success factors for facility management employer’s information requirements (EIR) for BIM
Authors: Ashworth Simon , Tucker Matthew , Druhmann Carsten K. 
Published: October 2018

PurposeThis paper aims to describe the development and testing of an employer’s information requirements (EIR) template and guidance document designed to meet client and facility management (FM) needs in the building information modelling (BIM) process.Design/methodology/approachA qualitative design approach was used and triangulation of methods which included a focus group with the British Institute of Facilities Management (BIFM), semi-structured interviews with the case study Glasgow Life Burrell Renaissance Project who trialled the EIR and peer-reviews and interviews with BIM/CAFM experts from the BIM Academy and FM180.FindingsSpecific guidance to help clients and facility managers prepare key BIM documents like the EIR are needed. They are aware of industry BIM standards and guidance but often not in detail. The Glasgow Life case study illustrated the EIR as a useful collaboration-tool to bring together stakeholders in early planning stages to understand client information needs.Social implicationsAssets and buildings account for most of the energy and material use in society. A well-structured EIR will help ensure the right information is available to enable optimisation of running costs and utility-use over their whole life, thus contributing to long-term sustainability.Originality/valueThis paper provides a new EIR template and guidance document ideal for practitioners in industry as a practical starting point to plan the client information requirements for BIM projects.

Educational mismatch in Europe at the turn of the century
Authors: Muñoz de Bustillo Llorente Rafael , Sarkar Sudipa , Sebastian Raquel , Antón Jose-Ignacio 
Published: October 2018

PurposeThe purpose of this paper is to present the stylised facts of over-education among European graduates over time (1998–2013), paying special attention to the measurement issues.Design/methodology/approachThe authors use two different sources, the Programme for the International Assessment of Adult Competencies 2012, and the European Union Labour Force Survey 1998–2013, with two different aims. The authors employ the first one to make a detailed analysis of the different forms of measuring over-education and its implications in terms of the result obtained. The analysis of the second one responds to studying the evolution and characteristics of over-education in Europe.FindingsIn the first place, the paper provides evidence of the high level of sensitivity of the level of measured over-education to the type of methodology used. Such difference is even higher when the authors focus on skills vs educational mismatch. The work also shows how with all their shortcomings, the measures of over-education used in the analysis point to the existence of convergence in over-education levels among the European countries of the sample (only interrupted by the crisis), in a context of reduction of over-education rates in many countries.Practical implicationsResearchers should be particularly careful when estimating over-education, because of the strong implications in terms of the so different results obtained when choosing between competing methods.Originality/valueThe analysis abounds in the implications of the use of different methodologies of estimating over-education in terms of both size and ranking among European countries. The production of long-run and updated estimates of over-education for a large sample of countries is done using a homogenous database and different estimation methods.
Skill mismatch comparing educational requirements vs attainments by occupation
Authors: Tijdens Kea , Beblavý Miroslav , Thum-Thysen Anna 
Published: October 2018

Purpose
The purpose of this paper is to overcome the problems that skill mismatch cannot be measured directly and that demand side data are lacking. It relates demand and supply side characteristics by aggregating data from jobs ads and jobholders into occupations. For these occupations skill mismatch is investigated by focussing on demand and supply ratios, attained vis-à-vis required skills and vacancies’ skill requirements in relation to the demand-supply ratios.

Design/methodology/approach
Vacancy data from the EURES job portal and jobholder data from WageIndicator web-survey were aggregated by ISCO 4-digit occupations and merged in a database with 279 occupations for Czech Republic, being the only European country with disaggregated occupational data, coded educational data, and sufficient numbers of observations.

Findings
One fourth of occupations are in excessive demand and one third in excessive supply. The workforce is overeducated compared to the vacancies’ requirements. A high demand correlates with lower educational requirements. At lower occupational skill levels requirements are more condensed, but attainments less so. At higher skill levels, requirements are less condensed, but attainments more so. Educational requirements are lower for high demand occupations.

Research limitations/implications
Using educational levels is a limited proxy for multidimensional skills. Higher educated jobholders are overrepresented.

Practical implications
In Europe labour market mismatches worry policy makers and Public Employment Services alike.

Originality/value
The authors study is the first for Europe to explore such a granulated approach of skill mismatch.
Estimating the size of the black economy: new evidence from India
Authors: Sharma Chandan 
Published: October 2018

PurposeThe issue of black economy has long been debated in India and it has been one of the key targets of policy action from last four decades. The debate is further fueled by demonetization of higher currency notes in the country. In this context, the purpose of this paper is to estimate the size of black economy in India for the period 1970–2017.Design/methodology/approachA currency demand approach is adopted for this purpose. The test of structure break indicates for a break in the system; therefore, the authors employ Johansenet al.(2000) cointegration test. For estimating the empirical model, the authors utilize fully modified ordinary least squares in a cointegration framework for taking care the endogeneity problem.FindingsThe estimates indicate that the Indian economy has a sizable black economy. In early 1970s, when the tax rate in India was significantly higher, the estimated black economy was above 30 percent of the official GDP. A variety of economic reforms including taxation, regulation and industrial licensing have drastically reduced the size to below 15 percent of official GDP in the last two decades. In the last estimated year (2017), the black economy was 23,849bn Indian rupees at current market price (around $400bn), which was 14 percent of the official GDP.Practical implicationsOn the basis of the findings, the authors suggest some important fiscal, administrative and regulatory reforms to curb the generation of black economy in India.Originality/valueThe structural breaks can induce stochastic behavior similar to an integrated process, which makes it difficult to differentiate between the lack of cointegration and a structural shift. Thus, in the present study, the authors attempt to address this issue by incorporating the issue of structural break in the analysis. Furthermore, India is a cash-based economy; therefore, it is likely that currency-based models are more suitable. The application of advanced time-series techniques is likely to yield better and robust results.
The economic determinants of the implied volatility function for currency options
Authors: Bhat Aparna Prasad 
Published: October 2018

Purpose
The purpose of this paper is to ascertain the pattern of the implied volatility function for currency options traded on the National Stock Exchange of India (NSE), identify its potential determinants and to investigate any seasonality in the pattern.

Design/methodology/approach
The paper examines four different specifications for the implied volatility smile of exchange-traded dollar-rupee options. These specifications are tested by running Ordinary Least Squares (OLS) regressions on a daily basis for all options over the entire sample period. Seven potential determinants for the shape of the volatility function are identified. Contemporaneous and lead-lag relationships between these determinants and the shape of the volatility function are examined using OLS and multivariate VAR. Impulse response functions are employed to test the strength and persistence of the lead-lag relations. Seasonality of the smile pattern is tested using OLS.

Findings
The study shows that the implied volatility function for dollar-rupee options is asymmetric and varies with the time to maturity of the option. Historical volatility, momentum and jumps in the exchange rate, time to maturity, traded volume of options and volatility in the stock market appear to Granger-cause the shape of the volatility smile. Feedback causality is observed from the shape of the smile to the volatility, momentum and jumps in the exchange rate and trading volume of currency options. A weak day-of-the-week effect is observed in the pattern of the volatility smile.

Practical implications
The study sheds light on the potential determinants of the smile and highlights the predictive power of the smile which findings can be useful to market practitioners for pricing and hedging of dollar-rupee options. The study has strong practical implications during a period of increased volatility in the dollar-rupee pair.

Originality/value
Most of the existing literature regarding implied volatility smiles has focused either on the volatility smile of US equity index options or that of major liquid currencies. There is a need for such studies in the context of options on emerging market currencies such as the Indian rupee which are characterized by thin trading and frequent central bank intervention and signaling. To the best of the author’s knowledge this study is the first to focus on the volatility smile of exchange-traded options on the US dollar–Indian rupee.
The transition probabilities for inflation episodes in Ghana
Authors: Adom Philip Kofi , Agradi Mawunyo Prosper , Quaidoo Christopher 
Published: October 2018

PurposeFollowing the reforms in monetary policy and shift in fiscal policies, it is logical to presume that these reforms may cause a significant structural change in the dynamic processes of inflation and hence affect the nature of inflation persistence. The purpose of this paper is to examine the persistence nature of the different inflation episodes while controlling for the effects of demand- and supply-side factors, which are modeled as regime-dependent.Design/methodology/approachThis paper used the Markov-switching dynamic regression and annual time series data.FindingsThe results showed that high inflation regime is more persistent than low inflation regime, with a respective average duration of an escape of 3.5 and 2.57 years, which suggests that price stability achievements are less sustainable. In both regimes, demand- and supply-side factors play significant roles in driving inflation, but the effect of the latter dominates. Thus, on the argument of whether inflation in Ghana is structural or monetary, the results support the former. The roles of both structural and monetary factors have changed over time, but that of the former has been more significant and important in Ghana.Originality/valueThis study provides the first empirical attempt, in the case of Ghana, that examines the persistence nature of different inflation regimes, while modeling the effects of supply and demand factors as regime dependent. In the modeling sense, the authors also contribute by ruling out the assumption that the researcher knows the processes responsible for each observation at each point in time.
Hong Kong, a gateway for mainland China? Examining the impact of luxury fashion retailers’ ownership structures on expansion strategies
Authors: Bai Huifeng , McColl Julie , Moore Christopher 
Published: October 2018

Purpose
The purpose of this paper is to examine luxury fashion retailers’ ownership structures at their internationalisation strategies in Hong Kong and mainland China.

Design/methodology/approach
This study adopts a pragmatic mixed methods approach, comprising a quantitative mail survey and ten qualitative executive interviews.

Findings
This study found that group-owned luxury fashion retailers usually encounter fewer difficulties when internationalising into mainland China than their individually owned counterparts because of parenting advantage, particularly functional and service support. However, the success of some individually owned brands has demonstrated that branding strategies, management culture, international experience, financial power and local partners’ know-how are as important as parent company support and although the luxury market in mainland China has become developed, many foreign luxury fashion retailers still enter Hong Kong prior to mainland China. However, in relation to post-entry management and expansion strategies, the importance of Hong Kong has weakened because the emergence of capital cities, the growth of the middle class and fewer political restrictions.

Research limitations/implications
The research findings are generated in the context of Hong Kong and mainland China, they are therefore limited in explaining luxury fashion retailers’ internationalisation strategies in other markets. Despite the challenge of the sample size, 63 out of 130 survey respondents (48.5 per cent response rate) and ten interview participants are felt to be sufficient to represent the market.

Practical implications
This research can be used by practitioners when assessing appropriate entry strategies to the Chinese luxury fashion market.

Originality/value
This is a pioneering study of the Chinese luxury market from the perspective of international retail strategies. It differentiates between Greater China (including Hong Kong, Macau and Taiwan) and mainland China, and examines the impact of luxury fashion retailers’ ownership structures on their internationalisation strategies.
Customer expectations and moderating role of demographics in fresh food retail
Authors: Antony Rose , Khanapuri Vivekanand B. , Jain Karuna 
Published: October 2018

PurposeThe purpose of this paper is to identify the dimensions of customer expectations and study the moderating role of demographics in the context of fresh food retail.Design/methodology/approachA structured questionnaire was designed using extant literature review followed by expert opinions. The survey was conducted among the customers in the twin cities of Maharashtra in India. The factors of customer expectations were identified using exploratory factor analysis (EFA) and further confirmed using confirmatory factor analysis in SPSS and AMOS, respectively. The significance of the customer expectations on customer satisfaction was studied using structural equation modeling. Subsequently, the role of demographics was studied using two-step cluster analysis and multigroup moderation.FindingsDuring EFA three factors emerged, namely, product-related features, in-store quality and store support services. Structural model evaluation found product-related features and in-store quality significantly influencing the customer satisfaction, while store support services were found as a non-significant factor in the region studied. Further, using cluster analysis customers were segregated into three groups, namely, traditional, autonomous and premium customers, where the premium customers were found to prefer the store support services on a higher scale, and similar results were obtained using multigroup moderation. Demographics, namely, gender, age, respondents’ income and marital status moderated for product-related features and in-store quality. Interestingly, respondents’ income also moderated for the store support services.Practical implicationsThe findings provide directions for store managers of the fresh food category to align supply chain decisions with the unique requirements of customers considering their socio-economic characteristics.Originality/valueOn the basis of social exchange theory, the authors found that in a mutually beneficial relationship, concerning the value proposition, retailers need to address the requirement of the different income group customers for store support services.
