Abstract

Purpose

Sargassum fusiforme is a popular edible seaweed in coastal cities of China that contains diverse nutrients including iodine. Cooking is an effective way to improve food safety, but it can alter both the contents of elements along with speciation and bioavailability. Three common cooking methods, the soaking, steaming and boiling, were evaluated for their effects on the protein structures, protein digestibility, iodine content and iodine bioavailability of S. fusiforme.

Design/methodology/approach

Fourier transform infrared spectroscopy was used to study the structural changes of protein, and an in vitro digestion/Caco-2 cell culture system was used to evaluate the digestibility of protein, bioaccessibility and bioavailability of iodine.

Findings

Boiling and steaming altered the protein secondary structure demonstrated by increased a-helix and random coil and decreased β-sheet, which improved the in vitro protein digestibility. Iodine content was reduced by cooking, with the highest loss observed after boiling, followed by soaking and steaming, while it was found that both bioaccessibility and cellular uptake of iodine were significantly elevated by boiling and steaming using an in vitro digestion/Caco-2 cell culture system. The presence of ascorbic acid, citric acid or tyrosine was beneficial for the iodine absorption, while oxalic acid and phytic acid hindered the iodine bioavailability.

Originality/value

The present finding suggested that cooking was conducive to the digestion and absorption of iodine in S. fusiforme. In addition, different dietary factors could have a certain impact on the absorption of iodine. Results of the study are essential for improving the application value of S. fusiforme to ensure reasonable consumption of seaweeds.

Abstract

Purpose

The performance of the measurement matrix directly affects the quality of reconstruction of compressive sensing signal, and it is also the key to solve practical problems. In order to solve data collection problem of wireless sensor network (WSN), the authors design a kind of optimization of sparse matrix. The paper aims to discuss these issues.

Design/methodology/approach

Based on the sparse random matrix, it optimizes the seed vector, which regards elements in the diagonal matrix of Hadamard matrix after passing singular value decomposition (SVD). Compared with the Toeplitz matrix, it requires less number of independent random variables and the matrix information is more concentrated.

Findings

The performance of reconstruction is better than that of Gaussian random matrix. The authors also apply this matrix to the data collection scheme in WSN. The result shows that it costs less energy and reduces the collection frequency of nodes compared with general method.

Originality/value

The authors design a kind of optimization of sparse matrix. Based on the sparse random matrix, it optimizes the seed vector, which regards elements in the diagonal matrix of Hadamard matrix after passing SVD. Compared with the Toeplitz matrix, it requires less number of independent random variables and the matrix information is more concentrated.

Abstract

Purpose

This study aims to investigate impacts of classic transaction cost-related factors (i.e. partner selection cost, specific asset investment and extorting rent cost) on joint venture (JV) partner’s cooperative and opportunistic behaviour, from the perspective of transaction cost economics.

Design/methodology/approach

Item measurements, based on which the questionnaire was developed, were derived according to a thorough search and review of related literature. In all, 226 valid responses from manufacturing enterprises in China were collected. A structural equation modelling approach was used to analyse the data and examine the fitness of the proposed model.

Findings

This study shows that partner selection cost, specific asset investment and extorting rent cost are positively related to a JV partner’s cooperative behaviour. Specific asset investment exerts the most significant influence on partner’s cooperative behaviour. The results also reveal that partner’s opportunistic behaviour is not significantly affected by specific asset investment but is negatively influenced by extorting rent cost. Both partner selection cost and extorting rent cost show positive impacts on specific asset investment.

Research limitations/implications

The investigation focused on only manufacturing enterprises in one country. Future research could be directed to investigating other countries to increase the generalizability of the findings.

Practical implications

The findings suggest that increasing the extorting rent cost to promote the probability of specific asset investment is a core element to enhance JV partner cooperation.

Originality/value

The study not only empirically investigates the relative importance of classic transaction cost-related factors on JV partner opportunism and cooperation, but also enables a deeper understanding of the interrelationship among the classic transaction cost-related factors and their influences on partner cooperation and opportunism.

Abstract

Purpose

This study aims to explore why Chinese consumers pay for digital content products by investigating the experiences of Chinese consumers living in first-tier and second-tier cities regarding paid digital knowledge products.

Design/methodology/approach

A total of 19 in-depth interviews were conducted to collect data, and the phenomenological reduction was adopted to analyze data.

Findings

This study reveals that Chinese consumers use paid digital knowledge products to alleviate stress and anxiety stemming from real-life competition and the fear of falling behind. While consumers acknowledge the limited assistance that paid knowledge products can offer, their acceptance and expectations of paid digital knowledge products remain positive.

Originality/value

Paid digital knowledge represents an innovative phenomenon, with few scholars outside China having studied it. This study contributes a conceptual framework to understand the motivations of Chinese consumers with high purchasing power residing in first-tier and second-tier cities to invest in digital content.

Abstract

Purpose

The purpose of this paper is to provide a conceptual model for examining the effects of trust (competence trust, goodwill trust) and cooperation on partner opportunism and for exploring the moderating effects of guanxi on the relationships among trust, cooperation and opportunism in joint ventures.

Design/methodology/approach

The sample for this paper comprises 981 manufacturing joint ventures from various industrial sectors. A total of 354 valid questionnaires were collected, representing a 36 per cent response rate. The conceptual model is tested with structural equation modeling adopting AMOS software.

Findings

The empirical findings indicate that both competence trust and goodwill trust reduce partner opportunism in a joint venture through fostering cooperation. Competence trust also exerts significant influence on preventing opportunism, whereas opportunistic behavior is not greatly affected by goodwill trust. Additionally, the results reveal that guanxi helps strengthen the negative relationship between cooperation and opportunism.

Originality value

This paper makes a threefold contribution: First, it investigates empirically the direct influence of two types of trust on partner opportunism. Second, it tests indirect influence of trust on partner opportunism through the path of cooperation. Third, it explores the moderating effects of guanxi in relationships on trust, cooperation and partner opportunism. Implications offers suggestions for management practice to reduce partner opportunism in joint-venture manufacturing.

Abstract

In this paper, we present a new hybrid binary version of bat and enhanced particle swarm optimization algorithm in order to solve feature selection problems. The proposed algorithm is called Hybrid Binary Bat Enhanced Particle Swarm Optimization Algorithm (HBBEPSO). In the proposed HBBEPSO algorithm, we combine the bat algorithm with its capacity for echolocation helping explore the feature space and enhanced version of the particle swarm optimization with its ability to converge to the best global solution in the search space. In order to investigate the general performance of the proposed HBBEPSO algorithm, the proposed algorithm is compared with the original optimizers and other optimizers that have been used for feature selection in the past. A set of assessment indicators are used to evaluate and compare the different optimizers over 20 standard data sets obtained from the UCI repository. Results prove the ability of the proposed HBBEPSO algorithm to search the feature space for optimal feature combinations.
