Abstract

Purpose

The purpose of this study is to examine factors that affect smallholders' adoption of improved rice varieties in Vietnam.

Design/methodology/approach

This study used a cross-sectional survey design. A random sample size of 257 was drawn from a total of 725 smallholders. Descriptive statistics and a binary logistic regression were used to analyse the data.

Findings

This study concludes that younger smallholders who participate in credit and training programs have a high level of education, receive government support, have both owned and rented land for growing rice and those who have a larger farm size have a greater tendency to adopt improved rice varieties. In addition, if improved rice varieties have higher productivity potential, palatability and marketability compared with the traditional ones as perceived by smallholders and seed of these rice varieties are available in local markets, then they are likely to be adopted by smallholders.

Research limitations/implications

A combination of socio-technological characteristics of smallholders should be considered when promoting smallholders' adoption of improved rice varieties and when choosing agricultural extension strategies to improve small-scale farmers' uptake of improved crop varieties in developing countries.

Originality/value

This research provides important understanding of the determinants of smallholders' adoption of improved rice varieties and highlights factors that need to be considered when designing policies to enhance the uptake of improved rice varieties in developing countries.

Abstract

Purpose

The purpose of this paper is to evaluate the chemical, physical and sensory composition of three new varieties of acerola (Rubra, Cabocla and CMF 017).

Design/methodology/approach

The samples of ripe acerola were collected from the Active Germoplasm Bank of Embrapa Cassava and Tropical Fruits – Cruz das Almas/Bahia, from the species Malpighia emarginata DC and analyzed by using standard methods.

Findings

The findings were that the Rubra variety stood out among the others in terms of flavour and purchasing intention, probably due to its pH 3.60, total acid (0.83 percent malic acid) and Vitamin C (911.97 g ascorbic acid/100 g) which gave the variety a less acidic flavour. As regards size, the average acceptability of this variety was 6.01, statistically different from Cabocla (8.08). Total anthocyanins were also found to be the highest, 76.7 mg/100 g and therefore the antioxidant activity of the peel was greater (85 percent) compared with the other varieties, though not differing statistically from the CMF 017 variety. According to these results, the Rubra variety is the one which should be of most interest to producers.

Practical implications

The new variety often fails to exceed nutritional and organoleptic characteristics of existing varieties in the market with established acceptance levels. The paper evaluates the chemical and sensorial composition of new varieties of acerola fruit, which could be launched on to the market. It was observed that one particular variety had better sensorial and nutritive quality.

Originality/value

This kind of data is important both for consumers who want to buy the best quality fruit and producers who want to plant more of the better quality variety so that they can gain greater added‐value in the commercialization of the fruit.

Abstract

Argues that the dichtomy between greater product variety to meet market requirement and a smaller range to save costs has always led to controversy among top executives. Researchers of different disciplines have approached the study of product variety in great depth but none of their work includes environmental considerations. Reports on a survey in Hong Kong which provides empirical evidence of the relationship between product variety and market performance. Concludes first, that previous work has seldom discussed the issues of product variety from an environmental perspective; second, that great product variety leads to irresponsible consumption patterns, i.e. waste; and, third, that firms have not considered the environmental impacts in formulating their product variety strategies.

Abstract

Purpose

Traditional production management systems are often designed to support manufacturing based on a limited number of product variants. With the emerging trend of producing customized products to meet diverse customer needs, the number of product variants increases exponentially in mass customization. In a situation of assembly‐to‐order production, production planning and control involve not only product variety, but also process variety. It is imperative to synchronize product and process variety in a coherent manner.

Design/methodology/approach

This paper discusses integrated product and production data management for assembly‐to‐order production. An integrated BOM and routing generator is proposed for the purpose of unifying BOM and assembly‐planning data in order to accommodate a wide range of product variability and production variations.

Findings

An integrated BOM and routing generator excels in variety synchronization for assembly‐to‐order production planning.

Research limitations/implications

Variety synchronization opens many opportunities for research into mass customization production. It is important to deal with not only the results of high variety production but also the causes of process variations.

Practical implications

The proposed methodology is applicable to manage high variety production like mass customization.

Originality/value

The paper proposes the variety synchronization issue in mass customization. An object‐oriented methodology is applied to manage variety of BOMs and variety of routings.

Abstract

Purpose – The objective of this chapter is to examine and provide new perspectives on the contributions of public and private R&D to biotech crop improvement.

Methodology/approach – The chapter examines a set of topics that have affected the way that research is undertaken on plant germplasm improvement and how it has changed with the genetically modified (GM) trait revolution.

Findings – Although the basic science providing the foundations for GM crops was undertaken in the public sector, GM traits and GM crop varieties have been developed almost exclusively by the private sector. The biotech events leading to GM traits are currently being developed largely by five companies – all having ties to both the chemical and the seed industries. The GM crop revolution started in North American in 1996 and has spread slowly to the largest developing countries that have large agricultural sectors, including Argentina, China, Brazil, and India, but not to Europe or Japan.

Practical implication – To shed new light on the economic reasons for private sector dominance in GM crop varietal development in selected crops but not in others.

Social implication – Shows how GM traits have contributed to technical change and declining real food prices.

Abstract

Purpose – The purpose of this chapter is to examine the connection between actual variety (the number of stock-keeping units (SKUs)) and amount of useable variety that the consumer perceives. The optimal combination for a retailer is to offer an assortment that maximizes the perceived assortment variety while minimizing the perceived inter-item complexity. Both measures are a function of the actual variety offered in an assortment but other factors such as attribute structure of the individual items, assortment organization, and individual differences can alter the way the actual variety is perceived.Design/methodology/approach – The main methodology used in the chapter is a comprehensive, critical literature review of the empirical research on the topic.Findings – We find that while assortments with a large number of SKUs are desirable for attracting consumers to the category, too large assortments can result in consumer frustration and confusion. On the other hand, when assortments are small, the perceived variety or attention to the category may be limited.Value/originality – Our review shows ways a retailer can adapt to these challenges. First, we show that assortments are viewed in stages. In the first stage, high perceptions of variety are beneficial. When assortments are small, increasing perceived variety can be accomplished by increasing the number of subcategories within the assortment, adding in packaging cues, or using other emotional affective descriptors to further define options within the assortment. In the second or choice stage, too much variety can increase perceived complexity. Perceived complexity at this stage can be reduced by simplifying the complexity of the individual items within the assortment by increasing alignability of attributes, using a simplifying external organizational structure for the assortment, or helping consumers learn their preference.

Abstract

Purpose

The paper aims to empirically investigate how demand variability impacts product category inventory levels and stockout rates of retail firms. Additionally, the moderating effect of product variety on these performance metrics is explored.

Design/methodology/approach

Using data from 78 individual retail stores of a single firm located in China, the authors develop a three stage least squares regression model to examine the simultaneous impact of product variety and demand variability on product inventory levels and stockout rates.

Findings

The results indicate that product variety and demand variability both negatively influence product category inventory levels and stockout rates. However, contrary to results for manufacturing or distributor environments, product variety dampens the negative relationship between demand variability and inventory.

Practical implications

For products or categories with a high amount of demand variability, retailers can leverage more product variety to help improve their inventory performance. This is likely due to product substitution behaviors.

Originality/value

The authors show that previously examined relationships between product variety, demand variability, and firm performance are different in the retail environment than in the manufacturing or distributor context.

Abstract

Purpose

In Nepal, not much is known about the adoption of improved vegetable varieties. Also, there are reasons to expect that the determinants of adoption may vary between subsistence and commercial farmers, given their different production/market orientations. Therefore, the paper aims to examine the adoption intentions of commercial and subsistence vegetable farmers.

Design/methodology/approach

A logistic regression model was used to empirically test the determinants of the intention to adopt and recommend improved vegetable varieties. The paper also uses propensity score matching (PSM) to assess the causal effects of production/market orientation on household dietary patterns. Cross-sectional data of 600 Nepalese vegetable farmers are analyzed.

Findings

Compared to subsistence farmers, commercial vegetable farmers obtain seeds mainly from formal sources and use hybrid seeds. The most consistent covariates of vegetable adoption intentions were risk preferences and experience growing vegetables. Overall, adoption intentions were higher among commercial farmers, and commercial vegetable households tend to consume more vegetables.

Practical implications

Considering that vegetable farming provides an important supplementary food production system for the household, adopting improved vegetable varieties is pivotal to increasing productivity and improving household level dietary diversity in developing countries. Actions to promote wider adoption of vegetable varieties and encourage healthier dietary patterns could be successful if these efforts also focus on subsistence farmers. The findings in this paper will be useful to policymakers to better prioritize dissemination strategies.

Originality/value

The paper highlights the differences in characteristics and adoption intention towards new vegetable varieties between subsistence and commercial farmers. The impact of commercial production on healthier household dietary patterns is accentuated.

Abstract

Purpose

This study aims to investigate the effect of winning-losing perception, including the winning or losing result and the closeness of this result, on consumers’ subsequent variety-seeking behavior.

Design/methodology/approach

Four experimental designs, one with a modified version of the Tetris game, were used to show how and when winning or losing perceptions will influence individuals’ variety-seeking behavior.

Findings

Consumers who have failed in a competition or not achieved a goal tend to seek less variety in their later consumption than do consumers who have succeeded because losing feedback weakens consumers’ perception of their control of personal mastery. This effect only exists when the closeness of winning or losing is narrow (e.g. the success is just missed) and diminishes when the result is clear and obvious.

Research limitations/implications

The current study has systematically explored the interaction between winning-losing outcomes and the closeness of these outcomes.

Practical implications

This study offers marketing managers practical guidance on how to use competition results to conduct marketing activities, such as transmitting advertisements for classic flavors to those who have lost in a video game or properly increasing the proportion of new flavors or products in stores or vending machines near sports venues.

Originality/value

This research adds to the literature on competition, which has largely overlooked the possible moderating role of the closeness of the competition result and its influence on individuals’ follow-up irrelevant behaviors and it also adds to the work on variety-seeking behavior, which has not explored the impact of winning-losing perception.
