Cluster identification
Authors: Manzini Reinaldo Belickas , Luiz Di Serio Carlos 
Published: September 2019

PurposeThis paper aims to contribute to the approaches based on traditional industry concentration statistics for identifying clusters by complementing them with the techniques of exploratory spatial data analysis (ESDA).Design/methodology/approachUsing a sample with 34,500 observations retrieved from the social information annual report released by Brazil Ministry of Labor and Employment, the methodology was designed to make a comparison between the application of industry concentration statistics and ESDA statistics.FindingsAs the results show, the geographic distribution measures proved to be fundamental for longitudinal studies on regional dynamics and industrial agglomerations, and the local indicator of spatial association statistic tends to overcome the limitation of the industry concentration approach.Research limitations/implicationsIn the period considered, due to economic, structural and circumstantial questions, activities linked to the transformation industry have been losing ground in the value creation process in Brazil. In this sense, the study of other industries may generate other types of insights that should be considered in the process of regional development.Originality/valueThis paper offers a critical analysis of empirical approaches and methodological advances with an emphasis on the treatment of special effects: spatial dependence, spatial heterogeneity and spatial scale. However, the regional dynamic presents a temporal dimension and a spatial dimension. The role of space has increasingly attracted attention in the analysis of economic changes. This work has identified opportunities for incorporating spatial effects in regional analysis over time.
Determinants of firm’s propensity to patent its inventions
Authors: Chandrashekar Deepak , M.H. Bala Subrahmanya 
Published: September 2019

Purpose
The purpose of this paper is to ascertain the factors that influence the decision of a firm in a cluster to patent its inventions.

Design/methodology/approach
This study adopts a stratified random sampling technique to choose 101 sample firms from the identified population of firms in a cluster. Further, it uses the primary data collection method to collect data from sample firms through semi-structured questionnaires and in-depth interviews with the top level management of the sample firms. Furthermore, it carries out binary logistic regression analysis to primarily examine the influence of capability and willingness factors of a firm on the propensity of a firm to patent its inventions.

Findings
The paper corroborates from the results of the binary logit model that invention capacity has a significant positive impact on a firm’s propensity to obtain patents. In addition, the absorptive capacity of a firm above a certain threshold is likely to have a significant positive influence on the decision of a firm to patent its inventions. On the one hand, between the two motivator factors conventional motivators and strategy related motivators, conventional motivator factor has a significant positive influence on a firm’s propensity to obtain patents. On the other hand, both the de-motivator factors (time, market and cost constraints and procedural issues) have a significant negative influence on a firm’s propensity to patent its inventions.

Originality/value
This paper makes a key contribution to the existing literature by empirically validating the influence of capability of a firm in terms of its invention and absorptive capacities, and willingness of a firm constituting motivator and de-motivator factors, on the decision of a firm to obtain patents, in the context of a firm in a high-tech manufacturing cluster in a developing economy.

Authors: Andonovski Jelena , Šandrih Branislava , Kitanović Olivera 
Published: September 2019

Purpose
This paper aims to describe the structure of an aligned Serbian-German literary corpus (SrpNemKor) contained in a digital library Bibliša. The goal of the research was to create a benchmark Serbian-German annotated corpus searchable with various query expansions.

Design/methodology/approach
The presented research is particularly focused on the enhancement of bilingual search queries in a full-text search of aligned SrpNemKor collection. The enhancement is based on using existing lexical resources such as Serbian morphological electronic dictionaries and the bilingual lexical database Termi.

Findings
For the purpose of this research, the lexical database Termi is enriched with a bilingual list of German-Serbian translated pairs of lexical units. The list of correct translation pairs was extracted from SrpNemKor, evaluated and integrated into Termi. Also, Serbian morphological e-dictionaries are updated with new entries extracted from the Serbian part of the corpus.

Originality/value
A bilingual search of SrpNemKor in Bibliša is available within the user-friendly platform. The enriched database Termi enables semantic enhancement and refinement of user’s search query based on synonyms both in Serbian and German at a very high level. Serbian morphological e-dictionaries facilitate the morphological expansion of search queries in Serbian, thereby enabling the analysis of concepts and concept structures by identifying terms assigned to the concept, and by establishing relations between terms in Serbian and German which makes Bibliša a valuable Web tool that can support research and analysis of SrpNemKor.
Auckland libraries as a multicultural bridge in New Zealand
Authors: Lin Wei Xia , Boamah Eric 
Published: September 2019

Purpose
The purpose of this research is to explore how immigrant library users view Auckland Libraries as a multicultural bridge in New Zealand. The research explored the various factors keeping different cultures apart in the New Zealand socio cultural systems and to find out the gaps in the provision of multicultural services in Auckland public libraries. The study also discusses the specific roles Auckland public libraries play in the development of multiculturalism in New Zealand from the perspective of immigrant users.

Design/methodology/approach
The study uses a qualitative research approach. Semi-structured interviews conducted with 15 participants including five library staff members and ten users of the Auckland library. Thematic analysis (qualitative data analysis, where data is grouped into themes) was used for data analysis.

Findings
Participants perceive that the Auckland Library had an advantage over other citizen service institutions in the development and services of multiculturalism in New Zealand. The participants understand that language, cultural background, beliefs and values are some of the causes of gaps between different ethnic groups, and only by learning from each other can groups enhance mutual understanding between them. The services and programs Auckland Library offer to immigrant enable various interactions among different cultural groups and enhance learning from one another to facilitate their integration into the New Zealand society. The findings show that Auckland public libraries have some gaps in multicultural services. In particular, there are more than 200 different ethnicities in Auckland, but the Auckland library's website does not have the function of a multilingual search tab service, lacks a multicultural book collection and some of the existing collections of books are of low quality, low literary value and so on. The study suggests that these issues need to be improved.

Research limitations/implications
This was small-scale research involving the perspectives of only 15 participants. Nevertheless, the findings provide constructive insight into the development of multicultural services in Auckland libraries that can serve as a useful basis for a broader exploration of more immigrant groups in Auckland and New Zealand as a whole.

Practical implications
The results of this research will provide valuable information for the Auckland libraries to have a better plan for multicultural services in the future. The findings will also serve as a reference for improving multicultural services in the Auckland libraries.

Originality/value
Although other studies have looked at immigrants’ behavior and perception on various issues in New Zealand, this study is the first to look at how different immigrant groups percept Auckland libraries as a multicultural bridge to help integrate them.
Efficiency wage, unemployment and tourism development: a theoretical analysis
Authors: Gupta Manash Ranjan , Dutta Priya Brata 
Published: September 2019

Purpose
International tourism has experienced a substantial growth during the second half of twentieth century. Tourism development can contribute substantially to the reduction of poverty problem by creating new employment opportunities. The purpose of this paper is to analyse the effect of tourism development on unemployment problem using an efficiency wage framework.

Design/methodology/approach
The authors developed a two-sector two-factor static competitive general equilibrium model of a less-developed open economy called South with an imported traded goods sector and with a non-traded tourism service sector, and with two factors, capital and labour. Labour is measured in efficiency unit; there exists unemployment in the labour market which is explained by the efficiency wage hypothesis. The authors also consider extensions of the basic model by introducing an exportable traded goods sector as well as sector-specific capital in the tourism sector.

Findings
The authors show that, with perfect intersectoral mobility of capital and with only one traded good, tourism development in South lowers unemployment rate and raises national income. However, this tourism development neither affects unemployment rate nor national income in South, in the mobile-capital model when there are two traded goods. When tourism sector uses sector-specific capital but capital is mobile between two traded goods sectors, tourism development keeps the unemployment rate unchanged but raises national income in South.

Originality/value
There exists a lot of debate about economic benefits of tourism development in a less-developed economy. A few works analyse the economic effects of tourism without developing formal models. However, no existing work analyses the effect on unemployment in an efficiency wage model. Although Harris–Todaro model is of relevance to explain unemployment in low-income countries, efficiency wage models are relevant for middle-income countries.
Time, money, or convenience: what determines Chinese consumers’ continuance usage intention and behavior of using tourism mobile apps?
Authors: Xu Feng , Huang Songshan (Sam) , Li Shuaishuai 
Published: September 2019

Purpose
This study aims to examine the effects of three aspects of perceived advantage (i.e. time-saving, money-saving and convenience) on Chinese consumers’ continuance usage intention and behavior of using tourism mobile applications (apps) in the context of Chinese society and culture.

Design/methodology/approach
Survey data were collected at 20 key tourist attractions in Jinan, China from tourists who visit the attractions. Structural equation modeling was applied to test the hypothetical model.

Findings
Empirical findings revealed that time-saving directly affected consumers’ continuance usage intention but did not influence user behavior; on the contrary, money-saving had a direct effect on user behavior, but not on intention. Convenience was found to affect both intention and behavior and had a much stronger total effect on user behavior than time-saving and money-saving.

Research limitations/implications
The study findings offer insights into the further development of tourism mobile apps. While money-saving can be an effective marketing offer for user adoption of tourism mobile apps, tourism mobile apps operators should further tap into the value of time and convenience in designing and developing tourism mobile apps.

Originality/value
The study expands on practical knowledge of Chinese consumers’ behavior toward using tourism apps.
Characterization of elastic-plastic corner deformation and stress fields
Authors: Yusoff Norwahida , Yusof Feizal 
Published: September 2019

PurposeThe purpose of this paper is to present the characteristics of elastic-plastic deformation and stress fields at the intersection of a crack front and the free surface of a three-dimensional body, referred to as corner fields.Design/methodology/approachThe structures of elastic-plastic corner deformation field were assessed experimentally by looking at the corner border displacement and strain fields on the surface of a compact tension (CT) specimen using digital image correlation method. For assessment and verification purposes, the results were compared with the fields predicted through finite element analysis. The latter method was used further to assess the corner stress field.FindingsThe characteristics of displacement, strain and stress fields in the vicinity of a corner vertex in a finite geometry CT specimen in a strain hardening condition are independent of load and geometry. One of the distinctive features that becomes evident in this study is that the stress state at the corner vertex atθ=0° is a simple uniaxial tension.Originality/valueThis paper provides some insights on the structure of elastic-plastic corner fields that could optimistically be served as a fundamental framework towards the development of analytical solutions for elastic-plastic corner fields.
Experimental investigation for the effect of fiber on the mechanical properties of light-weight concrete under dry and wet conditions
Authors: Nejati Faezeh , Edalatpanah S.A. 
Published: September 2019

Purpose
The purpose of this paper is to investigate the effect of steel and carbon fibers on the mechanical properties of light concrete in terms of tension strength, compressive strength and elastic modulus under completely dry and wet conditions.

Design/methodology/approach
In this study, the lightweight concrete made of Light Expanded Clay Aggregate (LECA) as coarse aggregate and sand as fine aggregate was used. To achieve a compressive strength of at least 20 MPa, microsilica was used 10 percent by weight of cement. In order to compensate for the reduction of tension strength of concrete, steel and carbon fibers were used with three volume ratio of 0.5, 1 and 1.5 percent in concrete. The results of concrete specimens were studied at the age of 7, 28, 42 and 90 days under controlled dry and wet conditions.

Findings
The results showed that the addition of steel and carbon fibers to the concrete mixture would reduce the drop in slump. Also, the use of steel and carbon fibers plays a significant role in increasing the tension strength of the specimens. Furthermore, the highest increase in tension strength of steel and carbon fiber samples was 83.3 and 50 percent, respectively, than the non-fibrous specimen when evaluated at 90 days of age. Moreover, the steel and carbon fiber increased the water absorption of the samples. Adding steel and carbon fibers to a lightweight concretes mixture containing LECA aggregates plays a significant role in increasing the modulus of elasticity of the samples. The highest increase in the elastic modulus of steel and carbon fibers was 18.9 and 35.4 percent, respectively, than the non-fibrous specimen at 28 days of age.

Originality/value
In this paper, the authors investigated the mechanical properties of steel fiber and carbon reinforced concrete. Also, according to the conditions of storage of samples and the age of concrete (day), the experiments were carried out on samples.
Is there a gender effect on wine choice in Portugal? – A qualitative approach
Authors: Ferreira Carla , Lourenço-Gomes Lina , Pinto Lígia M. Costa , Silva Ana Patrícia 
Published: September 2019

Purpose
The purpose of this paper is to analyze the existence and influence of gender effects on wine choice, specifically whether women and men seek the same cues in wine labelling.

Design/methodology/approach
Five focus groups, involving 45 regular wine consumers (22 women and 23 men) from four Portuguese wine regions of origin, were conducted. Sessions included two projective techniques. To gather more information, participants were asked to fill a short questionnaire, relating purchasing and consumption habits, knowledge and socioeconomic characteristics. Qualitative data were transcribed verbatim and content analysis was used.

Findings
Women frequently associate wine to the context of consumption; while men frequently associate wine to convivial and sensorial pleasure. Region of origin and prior knowledge experience seem to be the two main reasons for men to choose a wine; while, women seem to rely more on wine brand and previous experience. Front label information (region of origin, awards and region illustration) seems to be more important for women, while the back label descriptors (grape variety, world heritage site and wine history) are more relevant for men. The typography (font size) and information type were identified as negative aspects of the back label.

Practical implications
Understanding how men and women looking for information on a wine bottle can help marketers communicate with specific market segments. This paper provides insights to design marketing campaigns regarding product customization at the level of label information and design.

Originality/value
The present research contributes to current literature on wine consumer behaviour, exploring behavioural differences, perceptions and motivations by gender. In particular, the relevance of wine cues for choice decision is explored. The evidence of focus groups combined with projective techniques is complemented with data collected through a questionnaire.
Towards quality consumption
Authors: Hlédik Erika , Harsányi Dávid 
Published: September 2019

Purpose
Hungarian wine culture has been developing steadily over the past decades. The number of wineries offering quality wine is growing as consumer interest in quality consumption increases. The purpose of this paper is to study the segmentation of the Hungarian wine consumers based on their purchase habits and preferences to identify how this shift towards quality consumption is represented in these segments.

Design/methodology/approach
An online survey was conducted in Hungary. Nearly 28,000 consumers filled in the questionnaire. The TwoStep Cluster analysis could handle the large database and variables measured on different measurement scales.

Findings
The growing interest towards quality wine in the market is reflected in the study’s segmentation results. The large sample size made it possible to identify a special Hungarian wine consumer group, which has different buying habits than traditional wine consumer segments. Four segments were evolved: ordinary wine consumers, unsophisticated wine consumers, wealthy wine-experts and open-minded consumers. The last two segments seem to be the most valuable groups for high-quality wine producers.

Originality/value
The sample size allowed a relatively novel segmentation, whereby the preferences and purchasing habits of smaller, high-quality wine consumer groups became measurable.
Fabrication of curved overhanging thin-walled structure with robotic wire and arc additive manufacturing (RWAAM)
Authors: Li Yifeng , Qin Xunpeng , Wu Qiang , Hu Zeqi , Shao Tan 
Published: September 2019

Purpose
Robotic wire and arc additive manufacturing (RWAAM) is becoming more and more popular for its capability of fabricating metallic parts with complicated structure. To unlock the potential of 6-DOF industrial robots and improve the power of additive manufacturing, this paper aims to present a method to fabricate curved overhanging thin-walled parts free from turn table and support structures.

Design/methodology/approach
Five groups of straight inclined thin-walled parts with different angles were fabricated with the torch aligned with the inclination angle using RWAAM, and the angle precision was verified by recording the growth of each layer in both horizontal and vertical directions; furthermore, the experimental phenomena was explained with the force model of the molten pool and the forming characteristics was investigated. Based on the results above, an algorithm for fabricating curved overhanging thin-walled part was presented and validated.

Findings
The force model and forming characteristics during the RWAAM process were investigated. Based on the result, the influence of the torch orientation on the weld pool flow was used to control the pool flow, then a practical algorithm for fabricating curved overhanging thin-walled part was proposed and validated.

Originality/value
Regarding the fabrication of curved overhanging thin-walled parts, given the influences of the torch angles on the deposited morphology, porosity formation rate and weld pool flow, the flexibility of 6-DOF industrial robot was fully used to realize instant adjustment of the torch angle. In this paper, the deposition point and torch orientation of each layer of a robotic fabrication path was determined by the contour equation of the curve surface. By adjusting the torch angle, the pool flow was controlled and better forming quality was acquired.
Gesture-based human-robot interface for dual-robot with hybrid sensors
Authors: Zhang Bo , Du Guanglong , Shen Wenming , Li Fang 
Published: September 2019

Purpose
The purpose of this paper is the research of a novel gesture-based dual-robot collaborative interaction interface, which achieves the gesture recognition when both hands overlap. This paper designs a hybrid-sensor gesture recognition platform to detect the both-hand data for dual-robot control.

Design/methodology/approach
This paper uses a combination of Leap Motion and PrimeSense in the vertical direction, which detects both-hand data in real time. When there is occlusion between hands, each hand is detected by one of the sensors, and a quaternion-based algorithm is used to realize the conversion of two sensors corresponding to different coordinate systems. When there is no occlusion, the data are fused by a self-adaptive weight fusion algorithm. Then the collision detection algorithm is used to detect the collision between robots to ensure safety. Finally, the data are transmitted to the dual robots.

Findings
This interface is implemented on a dual-robot system consisting of two 6-DOF robots. The dual-robot cooperative experiment indicates that the proposed interface is feasible and effective, and it takes less time to operate and has higher interaction efficiency.

Originality/value
A novel gesture-based dual-robot collaborative interface is proposed. It overcomes the problem of gesture occlusion in two-hand interaction with low computational complexity and low equipment cost. The proposed interface can perform a long-term stable tracking of the two-hand gestures even if there is occlusion between the hands. Meanwhile, it reduces the number of hand reset to reduce the operation time. The proposed interface achieves a natural and safe interaction between the human and the dual robot.
