Purpose The purpose of this paper is to examine households’ acceptability of local (Ofada) rice by identifying the quality attributes influencing marginal implicit prices (MIPs) paid by rice consumers’ households in South-West, Nigeria. Design/methodology/approach The data used for this study were collected from a survey of 600 rice-consuming households in the study area. A multistage sampling technique was employed to select the respondents. Well-structured questionnaires were used to collect information on general households’ socioeconomic characteristics, their desirability and preference for local (Ofada) rice, and market prices of Ofada rice. Kendall’s concordance test was performed to confirm agreement among respondents in their rankings of the rice quality attributes. Hedonic price function was used to examine the relationship between implicit prices paid by consumers based on quality attributes of local (Ofada) rice, as observed in the market. Findings The result of Kendall’s coefficient of concordance revealed that there is 73.74 per cent agreement in ranking quality attributes of local (Ofada) rice consumers’ households in the study area. Colour, perceived nutrient level, taste, grain shape and rate of breakage were the most ranked quality attributes with mean attribute ranking scores of 1.56, 1.69, 3.12, 5.53 and 5.86, respectively. The result of the hedonic pricing model revealed that households are willing to pay MIPs of ₦71.03 ($0.20), ₦45.23 ($0.13), ₦32.98 ($0.09), ₦21.06 ($0.06) and ₦14.41($0.04) per kg for colour, grain cohesion, grain shape, perceived nutrient level and perceived chemical storage, respectively, while discounting MIPs of ₦60.55 ($0.17), ₦19.36 ($0.05), ₦17.14 ($0.05) and ₦6.00 ($0.02) for texture, rate of breakage, perceived freshness and low swelling capacity per kg of local (Ofada) rice, respectively. Research limitations/implications Continuous importation of rice into the country has many negative implications such as worsening of the poverty status of local rice farmers, unemployment of teeming youths engaged in rice value chain, and exposure to soaring and unpredictable price bringing unsustainable development. Lastly, over-dependency on rice importation, if not checked, can also permit dumping of low quality and sometimes expired rice into the country. All aforementioned reasons will make it difficult for local rice to compete favourably with imported varieties. Practical implications Kendall’s coefficient of concordance and Hedonic model were used as a diagnostic tools. These diagnostic tools show the need for government and relevant stakeholders to focus on improving the quality of local (Ofada) rice, especially the undesirable attributes. This could be achieved by adopting modern processing technology, that will enhance production and consumers’ acceptability, which could make local (Ofada) rice have good market share against imported brands. Social implications The economic value of a good is revealed by the consumer’s willingness to pay for the good, consequently increasing production through consumers’ acceptability, and improve living standard of farmers and processors through increased earnings. Originality/value The choice of a particular local rice, especially local (Ofada) rice, is made to estimate the effect of different attributes on the price paid by rice consumers’ households and to help in the development of effective technologies and policy that enhance better rice quality using both Kendall’s coefficient of concordance and Hedonic model to achieve the objective. For the first time this research has given clarity on the monetary value attached to local (Ofada) rice consumption by rice consumers’ households through quality attributes.

AbstractProduct placement survey data for 192 Asian-American households in Houston were used to analyze the value of rice quality attributes via the Consumer Goods Characteristics Model (CGCM). Five rice varieties were used for this study: domestic Lemont, Jasmine 85, Toro II, and two different Thai import varieties. For each variety, marginal implicit prices were calculated at the means for seven characteristics: color, texture, aroma, stickiness, flavor, aftertaste, and moisture.

Purpose The purpose of this paper is to evaluate the influence of the front of a package label and the nutritional claims linked to it over consumers’ expectations as to acceptance, purchase attitude and perception of quality characteristics of a new functional beverage made from cashew nut milk and added with mango juice and prebiotic substances. Design/methodology/approach Three versions of the front label were developed, which differed just by the type of nutritional claim presented (“0 per cent lactose and 0 per cent cholesterol; 0 per cent lactose, 0 per cent cholesterol and source of fibers, 0 per cent lactose, 0 per cent cholesterol and antioxidants”) and were evaluated in two phases, expectation and informed. For the evaluation, consumers used a multi-attribute scale, the nine-point hedonic scale and a nine-point semi-structured buying attitude scale. Findings The labels created a positive expectation on the consumers regarding the quality attributes, overall impression (mean = 6.0 “Like slightly”) and buying attitude (mean = 6.0 “Would probably buy”). After tasting the beverage associated with labels (informed phase), consumers kept a positive evaluation. The t-test performed between the pair of means of both phases showed that there has not been a significant difference regarding the quality attributes (p > 0.05), special, attractive, nutritive, healthy and buying attitude (Label 1, p = 0.26; Label 2, p = 0.18; Label 3, p = 0.26) in all labels. Originality/value The authors evaluated how the influence of label and nutritional claims in regards to a new product, a beverage made from cashew nut, affects its acceptance, buying attitude and characteristics of quality. Until this moment, there are no studies that evaluate how external attributes affect the acceptance of this beverage totally unique in the Brazilian market.

Purpose The Nigerian construction industry is bedeviled with poor project performance and outcomes which value management (VM) could address if applied. The application of VM on Nigerian construction projects is very minimal due to certain obstacles, namely, lack of VM experts, paucity of knowledge on the techniques, etc., which inhibits the adoption into the construction industry. Therefore, this study aims to develop a conceptual framework of the adoption of VM on construction projects in a typical developing economy. Design/methodology/approach This study engaged 15 selected VM experts in two rounds of Delphi survey to develop a conceptual framework of VM adoption. The method of data analysis includes mean score, standard deviation, Kendall’s coefficient of concordance, chi-square (χ2) test, interrater agreement analysis and significant level analysis. The developed conceptual framework was sent to a team of local and international VM experts for validation. Findings This study reveals that the adoption of VM requires the collective effort of relevant stakeholders in the construction industry. The framework developed presents individual and collective activities to be undertaken by the stakeholders. The activities include training, legislation, government-funded research, etc. Thus, the adoption of innovative management methodology like VM requires the collaboration of academics, construction professional bodies and government parastatals. This will assist in the judicious use of limited construction resources and boost the relevance of the Nigerian construction industry among developing nations and in the global construction market. Originality/value This study used the opinions of few construction professionals that can be regarded as VM experts in Nigeria, as against engaging a pool of construction professionals who may not be knowledgeable in VM process. Engaging the few VM experts in the Nigerian construction industry is important to have a valid basis for drawing conclusion, as large questionnaire survey could be possibly filled by inexperienced or unqualified respondents if stringent criteria are not considered at the outset of this study.

Purpose This paper aims to assess the drivers of value management (VM) in the Nigerian construction industry with a view to identify the critical ones through Delphi study. Design/methodology/approach A team of 15 carefully selected experts in VM were engaged in two rounds of Delphi survey, and the responses of the survey were analyzed with descriptive statistics (mean, standard deviation and mode). Kendall’s coefficient of concordance test and Chi-square (χ2) test were also used to test the level of consensus amongst the respondents at the two rounds of the survey to draw inference. Interrater agreement analysis and significant level analysis were further used to determine the criticality of critical drivers. Findings The critical drivers to VM adoption are adequate understanding of the benefits of VM, higher/postgraduate programme that teaches VM technique, professional’s previous experience with VM, collaboration of all construction professional bodies in Nigeria and VM training. Originality/value This paper used opinions of VM experts only to achieve the aim of this study as against the common survey method in which respondents who are not knowledgeable in the area of research might fill the questionnaire.

Purpose Studies have suggested that attributes are dynamic and a life cycle of product and service attributes exists. When an innovative feature is introduced, the feature might attract and delight customers. However, with the passage of time the state of the attractiveness of this feature may change, for better or for worse. The purpose of this paper is to provide a detailed model that shows the factors and related sub-factors that affect the life cycle of a feature and thereby explain the changes that may happen to a feature over time. Design/methodology/approach This model provide detailed explanations of the direct and indirect factors that affect the states of a feature, the ones that affect the rate of adoption, and the ones that trigger the changes between states. The model uses a current-market product’s feature to discuss the effects of these factors on the life cycle of this feature in detail. Findings This paper extends the theory of attractive quality attributes by identified seven states of the feature in its life cycle. These states are as follows: unknown/unimportant state, honey pot state, racing state, required state, standard state, core state, and dead state. This paper also identified eight major factors that affect the transition of the feature from one state to another. These factors include demographic, socioeconomic, behavioural, psychological, geographical, environmental, organisational, and technological factors. Originality/value The findings of this paper provide additional evidence that product and service attributes are dynamic. This paper also increases the validity of the attractive quality attributes theory and the factors that affect the state of the feature in its life cycle. The understanding of the state of the feature in its life cycle, and the factors that influence this change, helps not only in the introduction of completely new features but also in knowing when to remove obsolescent ones.

Purpose – The purpose of this paper is to describe recent passage of a private member's bill that can put Canada on a different path from the USA in attempting to resolve conflict that arose over how an influential clinical practice guideline for Lyme disease was developed. Design/methodology/approach – Narrative review. Findings – Critical appraisal of pertinent scientific literature is fundamental to the production of evidence-based practice guidelines. Perception of fairness and transparency in a guideline development process is fundamental to wide acceptance. Allegations of conflicts of interest and excluding opposing views in development of Lyme disease guidelines led to legislative interventions after insurers started basing denial of claims and licensing boards started responding to complaints against physicians whose treatment regimens were inconsistent with guideline statements on chronic Lyme disease. Opposing sides are both faced with limitations in available research evidence. Claims and counterclaims about availability of impartial subject matter experts free of vested interests arose; however, this has been compounded by failures in communication channels. Perhaps most importantly, and the focus of this viewpoint, wide perception among those afflicted of a flawed guideline development process makes it unlikely that all sides can reach agreement on this path. Canada, unlike the USA, is taking steps to include all stakeholders (including representatives of the medical community and of patients’ groups) in a review meeting to develop a comprehensive national framework. Research limitations/implications – This situation provides a noteworthy example of defining best practice in the difficult situations where stakes are high, diagnostic tools are flawed, some of those identified as experts have vested interests, and patients with unmet needs feel excluded. Originality/value – The next steps in Canada bear watching, both in terms of potentially resolving key conflicts around the one guideline document in question, and also as a potential model for a more successful guideline development process.

A Gram-stain-positive, motile, rod-shaped and endospore-forming strain, SYSU K30002T, was isolated from a soil sample collected from a karst cave in Xingyi county, Guizhou province, south-west China. SYSU K30002T grew at 28–40 °C (optimum, 37 °C), at pH 5.0–8.0 (optimum, pH 7.0) and in the presence of 0–4 % (w/v) NaCl (optimum in the absence of NaCl). The cell-wall peptidoglycan type was A4α (Lys–Asp). The cell-wall sugars of SYSU K30002T were ribose, galactose and mannose, and MK-7 was the menaquinone. The major fatty acids were iso-C15 : 0, C16 : 1 ω7c alcohol and iso-C16 : 0. The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and two unidentified phospholipids. The G+C content of the genomic DNA was 36.1 mol%. The average nucleotide identity values between SYSU K30002T and its closest relatives were below the cut-off level (95–96 %) for species delineation. Based on phenotypic, chemotaxonomic and genome comparisons, strain SYSU K30002T represents a novel species of the genus Lysinibacillus , for which the name Lysinibacillusantri sp. nov. is proposed. The type strain is SYSU K30002T (=KCTC 33955T=CGMCC 1.13504T).

Gambling Involvement

Purpose – The purpose of this paper is to investigate whether gambler’s cognitive errors affect gambling involvement and addiction. As the popularity of gambling has grown, questions are being raised about its excessive use and factors related to addictive behaviours. Design/methodology/approach – An online survey on 508 gamblers was conducted. Structural equation modelling was used to investigate the relationships among gambling beliefs, gambling involvement and problem gambling. Findings – Among the three sets of erroneous beliefs investigated, luck and superstition were significant predictors of both gambling involvement and the severity of gambling problems (according to the Problem Gambling Severity Index (PGSI)), while the illusion of control showed a negative relationship with the PGSI. Moreover, gambling involvement positively affected the potential risk of disease and mediates the relationship between luck and superstition and PGSI. Research limitations/implications – Because not all cognitive dimensions apparently influence gambling behaviour, future research should extend the analysis to include other variables that may moderate or mediate the causal relationship. Practical implications – The results are useful to marketers in developing social marketing campaigns wishing to discourage gambling. Moreover, factors that influence gambling involvement and addiction may be used as diagnostic tools to correct gamblers behaviour. Originality/value – The paper proposes a deeper exploration of the relationships among beliefs, gambling involvement and dysfunctional gambling and an appropriate scale to capture the entire spectrum of gambler’s beliefs in relation to every form of gambling activity.

PurposeThe purpose of this paper is to determine important attributes of processed food, consumers’ trust in different information resources, and the impact of trust, demographic and behavior variables on the preference of processed food attributes among Chinese consumers.Design/methodology/approachData of 1,267 participants were collected from four cities in China. A five-point Likert scale was used to measure consumer preference for 12 juice attributes. Consumer trust in nine sources of information on product quality was measured. Cluster analysis was used to segment consumers into groups based on their preference for juice attributes and trust in information sources, respectively. A multinomial logistic model was used to determine the impact of trust, demographic and behavior variables on the preference of juice attributes.FindingsConsumers rate manufacture date, taste and food safety labels as the most important attributes of fruit juice products. Among different information sources, consumers place more trust in private information sources and traditional media. The low trust in different information sources impedes consumer preference for processed food quality attributes.Originality/valueThis research is among the few that examine consumer preference for processed food, such as juice. It identifies four distinct preference groups and trust groups, respectively, based on consumer preference for juice attributes and trust in different information sources. This paper provides important information for processed food companies and policymakers to effectively enact marketing strategies in China.
