Published: June 2019

Purpose
The purpose of this paper is to investigate the ability of the computer vision system (CVS) to evaluate the colour of poultry meat. The advantages of the CVS over traditional methods were also explored.

Design/methodology/approach
The research was carried out on m. pectoralis major samples of three animals for each of the following four species: chicken, turkey, duck and goose. The total colour difference (ΔE) and the degree of difference of hue, chroma and lightness between the methods were calculated. In addition, a trained panel of 14 people was used to carry out three different similarity tests analysed using χ2 one sample test and one-way ANOVA. The correlation coefficient between CVS and colourimeter measures was evaluated using the Spearman rank correlation test.

Findings
The total colour difference (ΔE) between the methods employed was so large that the generated colour(s) could be considered more opposite than similar. The CVS-generated colour chips were more similar to the sample of the meat products visualised on the monitor compared to colourimeter-generated colour chips in all (100 per cent) individual trials performed. The use of the colourimeter for colour evaluation of lighter coloured poultry meat (chicken and turkey) was unrepresentative.

Practical implications
In this study, a CVS was developed to measure the colour of poultry meat as an alternative to conventional colourimeters.

Originality/value
The research has demonstrated that the use of a CVS should be considered a superior alternative to the traditional method for measuring colour of chicken, turkey, duck and goose meat.
Exploring claims and marketing techniques in Brazilian food labels
Authors: Pereira Rafaela Corrêa , de Angelis-Pereira Michel Cardoso , Carneiro João de Deus Souza 
Published: June 2019

Purpose
The purpose of this paper is to analyse the packaged food market in Brazil by examining the use of nutrition and health claims and marketing techniques, as well as the different levels of industrial food processing in relation to product category, nutrition information and price.

Design/methodology/approach
A survey was conducted on the labels of pre-packed foods and non-alcoholic beverages marketed in a home-shopping website in Brazil.

Findings
The authors showed that the use of nutrition and health claims on packaged foods in Brazil is widespread and varied across different food categories. Marketing techniques were also prevalent, and techniques emphasising general health, well-being or naturalness were the most frequent type used. Overall, products carrying nutrition and health claims and/or using marketing techniques had lower content of fat and higher content of fibre. However, the high prevalence of these strategies in ultra-processed foods is alarming. The presence of health claims and use of marketing techniques was not found to be an effective modifier of the three price measures. However, processed and ultra-processed foods were more expensive than unprocessed foods when considering price per energy and price per 100 g or mL.

Originality/value
These results indicate that there are clear opportunities to improve the packaged food environment in supermarkets. It is important to highlight the need to develop public policies to address these issues, including restriction of the promotion and advertising of unhealthy foods and beverages and use of warning labels.

Published: June 2019

PurposeThe purpose of this paper is to optimise and characterise the sensory aspects of gelatos flavoured with different types of coffee preparations (brewed, espresso and soluble), to select the most acceptable formulation and investigate the influence of hedonic claims on the consumer acceptance of this product.Design/methodology/approachFirst, the optimal concentration of each coffee type (brewed, soluble and espresso) to be added to the gelato was determined using the just-about-right scale. Second, the acceptance and purchase intentions towards gelatos flavoured with different concentrations of each type of coffee were determined. Finally, the most acceptable concentration for each flavour was selected based on purchase intentions and three other hedonic claims (i.e. texture, flavour and overall impression).FindingsThe estimated optimal concentrations of coffee (in relation to syrup) were found to be 111.09, 135.31 and 59.38 per cent for brewed, espresso and soluble coffee, respectively. Gelatos flavoured with soluble coffee were accepted more readily and associated with higher purchase intentions based on the evaluated sensory attributes (i.e. colour, taste, texture, softness and overall impression). The sensory perceptions towards these gelatos did not change significantly based on the evaluated hedonic claims (“coffee”, “soluble coffee” and “gourmet coffee”). This reveals that consumers may not be influenced by specific information and/or hedonic claims in the case of coffee gelatos.Originality/valueBesides encouraging the availability of a variety of coffee products on the market, this work also supports future studies aimed at the optimization of coffee products from a sensory perspective.
Understanding innovation in Canadian wine regions: an exploratory study
Authors: Doloreux David , Frigon Anthony 
Published: June 2019

Purpose
Despite the importance of innovation in and the growth of the wine industry in recent years, empirical research devoted to innovation in this industry remains scarce. The purpose of this paper is to contribute to filling this gap by exploring innovation among Canadian wine firms.

Design/methodology/approach
The data used in this paper are drawn from an original firm-level survey conducted between April and July 2018 to study the business and innovation strategies of Canadian winery firms over the 2015–2017 period.

Findings
First, the study has identified four innovation modes which are distinct in terms of firms’ strategy, innovation activities, and knowledge sourcing and openness. The second finding is that these different innovation modes are associated with different innovation outputs. The third finding is that there here is a tendency for certain innovation modes to better reflect firms in some regions, although all innovation modes are represented to different degrees in each of the three wine regions.

Originality/value
Empirical research devoted to innovation in this industry remains scarce. This paper contributes to filling this gap by exploring innovation among Canadian wine firms. These firms deal with several challenges and opportunities arising from the production and transformation of cool-climate grapes that impact on business innovation approaches.
Anti-diabetic and anti-proliferative activities of herbal teas,Athrixia phylicoidesDC andMonsonia burkeanaPlanch. ex Harv, indigenous to South Africa
Authors: Mathivha Lutendo Patricia , Thibane Vuyisile Samuel , Mudau Fhatuwani Nixwell 
Published: June 2019

PurposeThe purpose of this paper is to investigate the health and medicinal importance of bush tea (Athrixia phylicoidesDC) and special tea (Monsonia burkeanaPlanch. ex Harv), two of Southern African indigenous herbal teas.Design/methodology/approachThe two herbal teas,A. phylicoidesandM. burkeanawere extracted individually and in combined ratios for analysis. The phenolic content was determined and the different phenolic compounds were identified using thin-layer chromatography (TLC) and high-performance liquid chromatography (HPLC). The anti-diabetic activity of the teas was determined by evaluating the inhibition of bothα-amylase andα-glucosidasein vitro. The anti-proliferative activity was measured on human cervical cancer (HeLa) cell line using the MTT (3-(4,5-dimethylthiazol-2-yl)2,5-diphenyltetrazolium) assay.FindingsGallic acid, chlorogenic acid and quercetin were identified to be present in significant quantities by TLC. The HPLC quantified the presence of catechin (1.567 mg/g) and chlorogenic acid (1.862 mg/g) in special tea while chlorogenic acid (1.288 mg/g) was present in bush tea. Bush tea and special tea expressed significant levels of phenolic content and high antioxidant activities. Special tea (S100) expressed high inhibition ofα-amylase,α-glucosidase and HeLa cell line proliferation when compared to bush tea (B100).Originality/valueBoth bush tea and special tea could provide an alternative for treatment and management of both diabetes and cervical cancer. However, future studies are needed to investigate their synergistic effect with a wide range of other commercial herbal teas.

Authors: Kheireddine Bourahla , Zoubida Belli , Tarik Hacib 
Published: June 2019

Purpose
This paper aims to deal with the development of a newly improved version of teaching learning based optimization (TLBO) algorithm.

Design/methodology/approach
Random local search part was added to the classic optimization process with TLBO. The new version is called TLBO algorithm with random local search (TLBO-RLS).

Findings
At first step and to validate the effectiveness of the new proposed version of the TLBO algorithm, it was applied to a set of two standard benchmark problems. After, it was used jointly with two-dimensional non-linear finite element method to solve the TEAM workshop problem 25, where the results were compared with those resulting from classical TLBO, bat algorithm, hybrid TLBO, Nelder–Mead simplex method and other referenced work.

Originality value
New TLBO-RLS proposed algorithm contains a part of random local search, which allows good exploitation of the solution space. Therefore, TLBO-RLS provides better solution quality than classic TLBO.
Sensemaking questions in crisis response teams
Authors: Kalkman Jori Pascal 
Published: June 2019

Purpose
When a crisis strikes, responders need to make sense of it to gain an understanding of its origins, nature and implications. In this way, crisis sensemaking guides the implementation of the response. The purpose of this paper is to focus on the sensemaking questions that responders need to address for achieving effective and efficient crisis management.

Design/methodology/approach
Data are drawn from six exercises, in which teams of professionals from different crisis organizations were confronted with two terrorist attacks. Just like in real incidents, these professionals convened in tactical response teams and formulated their response collectively.

Findings
The exercises demonstrate that crisis responders do not just have to make sense of the crisis, but also of their own roles and actions. They raise and address three sensemaking questions: What is happening in this crisis? (i.e. situational sensemaking), Who am I in this crisis? (i.e. identity-oriented sensemaking) and How does it matter what I do? (i.e. action-oriented sensemaking).

Practical implications
Crisis preparation tends to focus on plans and systems that accelerate or improve the construction of a situational understanding, while this study suggests the need of more preparatory attention for crisis responders’ roles and actions.

Originality/value
The research extends crisis sensemaking literature beyond the restricted focus on the incident itself by showing that responders are also trying to grasp their own role and how their actions matter when they are engaged in crisis response.
Disambiguating USPTO inventor names with semantic fingerprinting and DBSCAN clustering
Authors: Han Hongqi , Yu Yongsheng , Wang Lijun , Zhai Xiaorui , Ran Yaxin , Han Jingpeng 
Published: June 2019

PurposeThe aim of this study is to present a novel approach based on semantic fingerprinting and a clustering algorithm called density-based spatial clustering of applications with noise (DBSCAN), which can be used to convert investor records into 128-bit semantic fingerprints. Inventor disambiguation is a method used to discover a unique set of underlying inventors and map a set of patents to their corresponding inventors. Resolving the ambiguities between inventors is necessary to improve the quality of the patent database and to ensure accurate entity-level analysis. Most existing methods are based on machine learning and, while they often show good performance, this comes at the cost of time, computational power and storage space.Design/methodology/approachUsing DBSCAN, the meta and textual data in inventor records are converted into 128-bit semantic fingerprints. However, rather than using a string comparison or cosine similarity to calculate the distance between pair-wise fingerprint records, a binary number comparison function was used in DBSCAN. DBSCAN then clusters the inventor records based on this distance to disambiguate inventor names.FindingsExperiments conducted on the PatentsView campaign database of the United States Patent and Trademark Office show that this method disambiguates inventor names with recall greater than 99 per cent in less time and with substantially smaller storage requirement.Research limitations/implicationsA better semantic fingerprint algorithm and a better distance function may improve precision. Setting of different clustering parameters for each block or other clustering algorithms will be considered to improve the accuracy of the disambiguation results even further.Originality/valueCompared with the existing methods, the proposed method does not rely on feature selection and complex feature comparison computation. Most importantly, running time and storage requirements are drastically reduced.
SEM-based numerical framework for non-Darcy mixed convection in a porous cavity with three adiabatic thin baffles on the hot wall
Authors: Wang Yazhou , Qin Guoliang , Ye Ximeng , Bao Zhenzhong 
Published: June 2019

Purpose
The purpose of this paper is to develop a numerical framework based on the accurate spectral element method (SEM) to simulate the mixed convective heat transfer within a porous enclosure with three adiabatic thin baffles of different lengths in nine cases and analyze the effects of several parameters.

Design/methodology/approach
The authors develop an improved time-splitting method to solve the Darcy–Brinkman–Forchheimer model. No extra assumptions are introduced for the intermediate velocity, and the final velocity field satisfies the incompressible constraint strictly compared with the classical method. The governing equations are split into a pure convection problem, a Stokes problem and a thermal diffusion problem. The least-squares variation is adopted for the Stokes problem, and the Galerkin variation is used for the other two problems, such that the pressure and velocity can be discretized with the same interpolation order, which benefits the numerical accuracy and program design.

Findings
Regarding the method, the excellent spectral accuracy, the capability of discretizing complex computational regions and the improved time-splitting methods make SEM an effective tool to accurately predict the non-Darcy convective heat transfer; as for the numerical tests, it is observed that weakened convection and heat transfer are induced by the increasing length of the baffles. The flow and heat transfer in channel 1 is only related to the length of baffle 1 because of the downward-driven right sidewall, and it is more difficult for baffle 3 to form the secondary flow on its tip.

Originality/value
A novel numerical framework for Darcy–Brinkman–Forchheimer model is developed, expanding the application of SEM for simulating non-Darcy convective heat transfer to improve the numerical accuracy. Numerical results and analysis for flow and heat fields could help designers understand the control of heat transfer using adiabatic baffles better.
From theory to practice: guidelines for enhancing information security management
Authors: Topa Ioanna , Karyda Maria 
Published: June 2019

Purpose
This study aims to identify the implications of security behaviour determinants for security management to propose respective guidelines which can be integrated with current security management practices, including those following the widely adopted information security standards ISO 27001, 27002, 27003 and 27005.

Design/methodology/approach
Based on an exhaustive analysis of related literature, the authors identify critical factors influencing employee security behaviour and ISP compliance. The authors use these factors to perform a gap analysis of widely adopted information security standards ISO 27001, 27002, 27003 and 27005 and identify issues not covered or only partially addressed. Drawing on the implications of security behaviour determinants and the identified gaps, the authors provide guidelines which can enhance security management practices.

Findings
The authors uncover the factors shaping security behaviour barely or partly considered in the ISO information security standards ISO 27001, 27002, 27003 and 27005, including top management participation, accommodating individual characteristics, embracing the cultural context, encouraging employees to comply out of habit and considering the cost of compliance. Furthermore, the authors provide guidelines to security managers on enhancing their security management practices when implementing the above ISO Standards.

Practical implications
This study offers guidelines on how to create and design security management practices whilst implementing ISO standards (ISO 27001, ISO 27002, ISO 27003, ISO 27005) so as to enhance ISP compliance.

Originality/value
This study analyses the role and implications of security behaviour determinants, discusses discrepancies and conflicting findings in related literature, provides a gap analysis of commonly used information security standards (ISO 27001, 27002, 27003 and 27005) and proposes guidelines on enhancing security management practices towards improving ISP compliance.
Value co-creation in sport entertainment between internal and external stakeholders
Authors: Erhardt Niclas , Martin-Rios Carlos , Chan Elisa 
Published: June 2019

Purpose
Co-creation as a collaborative process between organizations and customers generates unique value for both internal and external stakeholders for the company. Research generally examines and portrays customer-company co-creation as a balanced and harmonious relationship. However, a successful co-creation strategy involves understanding the shared interests of the parties and resolving tensions between internal and external stakeholders to avoid co-destruction. This study aims to draw on the intersection of organizational behavior and marketing literature and to examine shared interests and conflicting tensions involved in the co-creation in the context of sports entertainment. This context allows the researchers to unpack and present a more complex process of co-creation that fosters co-creativity and innovation.

Design/methodology/approach
Based on a qualitative case-based approach of a major university in the USA, the authors draw on interviews and observations from their athletic administration and fans engaged in a men’s Division I team through an entire season.

Findings
This qualitative study illustrates an alternative, more complex dilemma of co-creating emotional and symbolic value based on shared interests while reconciling conflicting internal and external stakeholder interests. The findings suggest a tug of war based on tensions, where management adopted contrasting managerial strategies ranging from attempting to reconcile tension through organic co-creation to controlled manufactured creation.

Research limitations/implications
Emotional and symbolic game experience value is an interdependent process which cannot be created without consumer engagement. Both emotional and symbolic values are enhanced during games to the extent consumers perceive participation in the creative pre-game stages.

Originality/value
This study draws on sports entertainment to identify sources of tension in co-creation and discuss type of solutions among internal and external stakeholders.
Pubscape: innovation by design in the British pub
Authors: Martin Lynn , Jerrard Bob , Wright Lucy 
Published: June 2019

Purpose
The decline of the British public house (pub), well documented over the past three decades, is often linked to detrimental social and economic conditions in communities. The purpose of this study was to explore brewery responses to turbulent market conditions for the pub trade, with a focus on innovation through design.

Design/methodology/approach
A longitudinal, qualitative study was conducted over 12 months, with 4 months of close participant observation within the company, to explore the experiences of a design team located within a medium-sized UK brewery.

Findings
The “pubscape” emerged, extending and augmenting earlier models of the “servicescape”, driven by an entrepreneurial shared vision recognising the importance of design and innovation in delivering the modern pub.

Research limitations/implications
A single case – one brewery – formed the basis for a longitudinal qualitative study, with the associated benefits and disadvantages typical of single case research in providing insights rather than measurable outcomes. Other cases and other research methods would allow testing of ideas, rather than exploration, and generate different perspectives.

Practical implications
The research indicates the value of adopting an entrepreneurial approach to address challenging trading conditions and shows the practical role that design can play in rethinking service offerings to fit consumer needs and aspirations.

Originality/value
New insights into modern pub management have emerged from this study, positioning design innovation as a route to delivering successful British destination pubs by innovating while retaining traditional brand values and local identity markers, using the “pubscape” as a specific way to envisage innovative servicescape environments.
