Abstract

Mass customisation involves the provision of product variants that fulfil clients' specific requirements seeking to increase product values. The configuration process involves a chain of decisions, which needs to be undertaken to create product variants that meet each client specific requirements. In this paper, this chain of decisions is conceptualized in terms of customisation units. Each customisation unit encompasses a customisable attribute (e.g. size, colour) and the range of items offered for this attribute. A design science approach was adopted in this investigation. In this approach, knowledge is produced by creating and testing a solution, which provides practical and theoretical contributions. A method is proposed to analyse and improve the configuration process by conceptualizing this process as a tree diagram. The proposed method is used to analyse the configuration process developed by organisations of the house-building sector based in the U.K. and Brazil: a manufacturer of floor tiles, contractors, and registered providers. These analyses enabled a comparison of the distinct configuration processes adopted. In addition, problems associated to the configuration process (such as burden of choice) and opportunities for improvements were also identified. Finally, alternative chains of decision were also devised based on these analyses to address the problems identified.

Abstract

Purpose

As studies investigating the effects of fructan sources, such as yacon, on glucose and lipid metabolism showed different results, additional research is required to establish a clear relationship between them. Thus, this paper aims to evaluate possible effects of the consumption of the yacon pulp flour (YPF) on biological and metabolic parameters such as food consumption, weight gain, serum glucose levels and fecal lipid excretion of rats, as well as determine the role of glycemic index (GI) of the diets added of this ingredient on those parameters.

Design/methodology/approach

For this purpose, 24 male albino Wistar rats were divided into four groups, which received the following treatments for 17 days: Group 1 (G1) (Control) – American Institute of Nutrition (AIN)-M; Group 2 (G2) – AIN-M added 5 per cent YPF; Group 3 (G3) – AIN-M added 10 per cent YPF and Group 4 (G4) – AIN-M added 15 per cent YPF. Analysis of fasting and postprandial glycemia was conducted for elaboration of the glycemic curve and calculation of the GI of the diets. Lipids loss was measured by quantification of crude fat in feces after consumption of the diet.

Findings

YPF, regarding the concentration in the diets, did not elevate the fasting glucose among the groups. The postprandial glucose of the animals declined in different postprandial glucose peaks of the groups ingesting YPF in relation to the control one, especially in group treated with 15 per cent YPF, between 30 and 60 min (p <0,05), confirming the influence of the dietary fiber on the absorption of the glucose. The ingestion of YPF increased dragging of lipids to the animal feces, proportional to the amounts of YPF added to the diets. According to the regression analysis, followed by regression testing to 5 per cent, there was a significant difference between the experimental groups, being that the elevation of the percentage of YPF added to the diet caused a proportional increase in the lipid levels in the animal feces.

Originality/value

YPF could be an alimentary source of interest, mainly when the focus is on disease risk prevention such as diabetes, obesity and dyslipidemias.

Abstract

Globalisation is generally defined as the “denationalisation of clusters of political, economic, and social activities” that destabilize the ability of the sovereign State to control activities on its territory, due to the rising need to find solutions for universal problems, like the pollution of the environment, on an international level. Globalisation is a complex, forceful legal and social process that take place within an integrated whole with out regard to geographical boundaries. Globalisation thus differs from international activities, which arise between and among States, and it differs from multinational activities that occur in more than one nation‐State. This does not mean that countries are not involved in the sociolegal dynamics that those transboundary process trigger. In a sense, the movements triggered by global processes promote greater economic interdependence among countries. Globalisation can be traced back to the depression preceding World War II and globalisation at that time included spreading of the capitalist economic system as a means of getting access to extended markets. The first step was to create sufficient export surplus to maintain full employment in the capitalist world and secondly establishing a globalized economy where the planet would be united in peace and wealth. The idea of interdependence among quite separate and distinct countries is a very important part of talks on globalisation and a significant side of today’s global political economy.

Abstract

Purpose

Flours obtained from pulps and peels of unripe banana were evaluated regarding their chemical composition and glycemic responses in rats. Moreover, this study aims to propose a new assay to measure glycemic responses using animals.

Design/methodology/approach

Proximal composition, total dietary fiber and its insoluble and soluble fractions, mineral content and tannins were evaluated. Glycemic responses were measured using albino Wistar rats (seven animals/group).

Findings

Flours from pulp and peel of unripe banana presented high content of carbohydrates and minerals. Moreover, flour from peel was rich in insoluble fiber, whereas flour from pulp had adequate proportion of insoluble and soluble fractions. Consumption of banana flours from peel and pulp did not affect fasting blood glucose of normoglycemic rats. Flour from pulp, when consumed in concentrations of 10 and 15 per cent of the diet, significantly stimulated lower glycemic responses in the animals.

Originality/value

Results presented in this study disclose unripe banana flour as an interesting food source, which may be indicated for preventing some types of diseases, such as diabetes, obesity and dyslipidemia. Moreover, the glycemic index assay using animals promoted accurate answers, as the diets were standardized, unlike studies with humans, which do not control variations related to omission and distortion of information regarding food intake.

Abstract

Purpose

The purpose of this paper is to deepen the discussion regarding the competitiveness of clusters based on a theoretical and empirical study that compares the level of competitiveness of the Brazilian wine cluster located in Serra Gaúcha with the competitiveness of the Chilean cluster located in Valle del Maule.

Design/methodology/approach

A qualitative-descriptive approach was applied to the study, and data collection was conducted through secondary sources.

Findings

The analysis employed a competitiveness analysis model consisting of 11 competitiveness factors. The Chilean cluster presented a higher level of competitiveness in four competitiveness factors (“scope of viable and relevant business,” “introduction of new technologies,” “balance with no privileged positions” and “oriented strategy”), while the Brazilian cluster presented a higher level of competitiveness in three competitiveness factors (“concentration,” “cooperation” and “replacement”). For four of the competitiveness factors of the model, both clusters presented similar levels of competitiveness.

Practical implications

By comparing the two wine clusters, it was possible to identify aspects that can be improved to increase competitiveness, especially in the Brazilian cluster. These aspects include, first, the need for bottle manufacturers in Serra Gaúcha, which would have a positive impact on production costs; second, the expansion of the geographical indication registration for the entire Serra Gaúcha region, resulting in an enhanced image of Brazilian wine abroad; and third, greater incentives for exports, which would result in an increase in market share.

Originality/value

The paper proposes an explanation for the superior level of competitiveness of the Chilean cluster regarding the “scope of viable and relevant business,” “balance with no privileged positions,” “introduction of new technologies” and “strategy focussed on cluster development.” In terms of its contribution, the study developed additional metrics for the model adopted, which can be used for the competitive analysis of other agribusiness clusters.

Abstract

Purpose

The purpose is to create an algorithm that optimizes the trajectories that an autonomous vehicle must follow to reduce its energy consumption and reduce the emission of greenhouse gases.

Design/methodology/approach

An algorithm is presented that respects the dynamic constraints of the robot, including the characteristics of power delivery by the motor, the behaviour of the tires and the basic inertial parameters. Using quadratic sequential programming with distributed and non-monotonous search direction (Quadratic Programming Algorithm with Distributed and Non-Monotone Line Search), an optimization algorithm proposed and developed by Professor K. Schittkowski is implemented.

Findings

Relations between important operating variables have been obtained, such as the evolution of the autonomous vehicle’s velocity, the driving torque supplied by the engine and the forces acting on the tires. In a subsequent analysis, the aim is to analyse the relationship between trajectory made and energy consumed and calculate the reduction of greenhouse gas emissions. Also this method has been checked against another different methodology commented on in the references.

Research limitations/implications

The main limitation comes from the modelling that has been done. As greater is the mechanical systems analysed, more simplifying hypotheses should be introduced to solve the corresponding equations with the current computers. However, the solutions are obtained and they can be used qualitatively to draw conclusions.

Practical implications

One main objective is to obtain guidelines to reduce greenhouse gas emissions by reducing energy consumption in the realization of autonomous vehicles’ trajectories. The first step to achieve that is to obtain a good model of the autonomous vehicle that takes into account not only its kinematics but also its dynamic properties, and to propose an optimization process that allows to minimize the energy consumed. In this paper, important relationships between work variables have been obtained.

Social implications

The idea is to be friendly with nature and the environment. This algorithm can help by reducing an instance of greenhouse gases.

Originality/value

Originality comes from the fact that we not only look for the autonomous vehicle’s modelling, the simulation of its motion and the analysis of its working parameters, but also try to obtain from its working those guidelines that are useful to reduce the energy consumed and the contamination capability of these autonomous vehicles or car-like robots.

Abstract

Purpose

The purpose of this paper is to characterize consumers of traditional foods, taking as case study fresh cheeses produced in a village, in Central Mexico.

Design/methodology/approach

Semi-structured interviews were applied to a sample of 150 consumers, selected by non-probabilistic convenience sampling. A factorial analysis by principal component analysis was performed to the data, followed by a cluster analysis.

Findings

Four factors were obtained, named: artisanship, health and well-being, liking, and satisfaction with the purchase. Three consumer groups were identified: practical, in the process of valorization, and with liking and tradition. The socioeconomic characteristics of consumers do not have a relationship in the classification of groups. It is concluded that the consumption of fresh cheeses is due to a number of social and cultural attributes, and in lesser proportion, to economic aspects.

Originality/value

At present, as part of life in a dynamic society, people have the power of choice in the food they consume, a process that involves cultural, social, economic, political, and ideological aspects, established by the consumers themselves, or by a determined social group to which they belong. This has not been researched in Mexico. Being an emerging economy immersed in a rapid process of globalization, studies like this contribute in similar countries of Latin America and other places to find ways to valorize local foods and products that play important roles in the development of rural communities.

Abstract

Purpose

Keeping in view the diabetes status that has affected about 415 million people globally and is the leading cause of death in many countries along with therising demand for low Glycemic Index (GI) foods, the purpose of this paper is to optimize the extrusion process for the development of low GI snacks from underutilized crops like water chestnut and barley.

Design/methodology/approach

The extrusion parameters (screw speed and barrel temperature), feed moisture and water chestnut flour, barley flour proportion, were varied and their effects on system and product responses (specific mechanical energy, water absorption index, water solubility index, bulk density, expansion ratio and breaking strength) were studied.

Findings

All the system and product responses were significantly affected by independent variables. Response surface and regression models were established to determine the responses as function of process variables. Models obtained were highly significant with high coefficient of determination (R2=0.88). The optimum processing conditions obtained by numerical optimization for the development of snacks were 90°C barrel temperature, 300 rpm screw speed, 14 per cent feed moisture and WCF-to-BF ratio as 90:10. Shelf life studies confirmed that the developed snacks can be safely stored in HDPE bags for a period of six months under ambient conditions.

Originality/value

Water chestnut and barley flour did not blend till date for extrusion cooking. Such snacks shall be a viable food option for diabetic people and can act as laxative due to high fibre and β-glucan content from barley.

Abstract

This paper presents a comparative analysis of artwork produced in the context of social movements waged by Mexicans and Chicanos (U.S. inhabitants of Mexican descent) during the two decades between the mid-1960s and the mid-1980s. Despite the fact that activists in these movements shared many elements of Mexican culture and history, were part of the same generation of radical social movements born in the 1960s, and experienced some significant interchange among movement participants from each side of the U.S.-Mexico border, an examination of movement art reveals significant differences in key elements of the movements’ collective identity and expression of political citizenship. Analysis of the artwork also highlights different aesthetic choices made by movement artists, particularly with regard to the deployment of formal elements associated with the “Mexican School” of art made famous by artists associated with the Mexican Revolution of the early 20th century. Variations in the representational strategies developed by movement artists reflect the distinct relationship of movement constituents in Mexico and the U.S. to each nation's prevailing regimes of accumulation and modes of regulation. The analysis is based on an examination of 374 pieces of art.

Abstract

Purpose

The purpose of this paper is to review the concepts of “fun and play” and propose a preliminary model that suggests potential benefits for quantitatively/qualitatively rating serious games and simulations associated with corporate and university game-based learning (GBL).

Design/methodology/approach

A relevant literature review was executed to locate significant references to fun and play, assessment of GBL, and the pattern for integrating those elements with knowledge mobilization (KMb). A repertory grid method (RGM) was used to propose a preliminary model.

Findings

The proposed FUNIFICATION Model will be useful as a foundation for further evaluation of GBL environments.

Research limitations/implications

Additional rationalization of the proposed model and applying it to actual games with focus groups as the observers would provide additional validity to the new model.

Practical implications

A threshold for fun involved in serious games and simulations would provide a quantitative/qualitative measure for playability of serious games and simulations. The FUNIFICATION Factor would feed into a KMb model for acquiring, codifying, disseminating, and making knowledge actionable, either within academic, corporate, or public sector environments.

Originality/value

The range of assessment models for GBL is evident from the literature review, and value could be derived in building an evaluation model based upon the RGM to identify a FUNIFICATION Factor for serious games and simulations.
