Abstract

In this paper, silk powder around 1.5 micrometer average in size was developed and its dyeing property was compared with normal silk fiber. The results show that silk powder has a very high dye uptake property and can be dyed at room temperature; it can also be used to improve the dyeing property of some materials when it acts as a kind of additive agent. The K/S value of silk fiber is higher than that of silk powder. Their K/S value of silk fiber and silk superfine powder are influenced largely by the dye concentration. The WXRD diffraction curves showed that the crystallinity of silk powder is lower than that of silk fiber. FTIR spectra of silk powder showed that the intensity peak of CH2-antisymmetrical stretching vibration largely decreased, and the peak of C=O symmetrical stretching vibration of amid bond moved to the high wave-number. TG patterns of samples showed that water (moisture) could be easily removed from the powder when the temperature was over 70°C, and the initial decomposition temperature of silk powder increased from 262.5°C to 277.5°C. Moreover, the silk powder showed higher residue than that of silk fiber at 600°C.

Abstract

Purpose

The purpose of this paper is to examine visitors’ motivations for going to the South Luogu Alley, a famous hutong with an over 700-year history in Beijing, China.

Design/methodology/approach

The study applied a self-administered questionnaire to collect data from visitors on the main street of the South Luogu Alley.

Findings

It was found that most visitors of the hutong are casual tourists pursuing relaxation, including tension release and spending time with friends and family; seeking authenticity is not visitors’ most important motivation.

Research limitations/implications

This study used only one hutong to assess visitors’ motivations in hutong tourism, so the results may not be applicable to all hutongs.

Practical implications

The research on the demographics and different motivations of the South Luogu Alley visitors can be useful to managers of tourism-related organizations.

Social implications

This study shows that tourists with different motivations for visiting a hutong have varying requirements for authenticity. The reconstruction of some historical hutongs is not always perceived as negative, and the influence of Western cultural elements can be seen as positive if they contribute to the sustainable development of the local culture.

Originality/value

The term “hutonger,” which includes casual visitors, entertainment seekers, authenticity seekers and pure escapees, based on these respective motivations, is introduced to describe the specific groups of hutong visitors and contribute to the hutong tourism literature.

Abstract

Purpose

The purpose of this paper is to value put option contracts in hedging the risks in a supply chain consisting of a component supplier with random yield and a manufacturer facing stochastic demand for end products.

Design/methodology/approach

This paper adopts stochastic inventory theory, game theory, optimization theory and algorithm and MATLAB numerical simulation to investigate the manufacturer’s ordering and the supplier’s production strategies, and to study the coordination and optimization strategies in the context of random yield and demand.

Findings

The authors find that put options can not only facilitate the manufacturer’s order but also the supplier’s production, that is, the manufacturer and the supplier can effectively manage their involved risks and earn more expected profits by adopting put options. Further, the authors find that the single put option contract fails to coordinate such a supply chain. However, when combined with a protocol, it is able to coordinate the supply chain.

Originality/value

This paper is the first effort to study the intersection of put option contracts and random yield in the presence of a spot market. From a new perspective, the authors explore the supply chain coordination. The authors propose a mechanism to coordinate the supply chain under put option contracts.

Abstract

Purpose

The purpose of this paper is to build a comprehensive structural model to demonstrate the interrelationships of factors influencing social networking service (SNS) fatigue and to identify the varying degrees of influence.

Design/methodology/approach

A total of 14 factors influencing SNS fatigue are identified through an extensive literature review. Interpretive structural modeling (ISM) and Matrice d'Impacts Croisés Multiplication Appliqué à un Classement (MICMAC) analysis are employed to build a hierarchical model and classify these factors into four clusters.

Findings

The results revealed that ubiquitous connectivity and immediacy of feedback are key factors contributing to SNS fatigue through their strong influence on other factors. Privacy concern, impression management concern and work–life conflict lead directly to SNS fatigue. In contrast, system feature overload and system pace of change are relatively insignificant in generating SNS fatigue.

Originality/value

This study represents an initial step toward comprehensively understanding the interrelationships among the factors leading to SNS fatigue and reveals how determinants of SNS fatigue are hierarchically organized, thus extending existing research on SNS fatigue. It also provides logical consistency in the ISM-based model for SNS fatigue by grouping identified factors into dependent and independent categories. Moreover, it extends the applicability of the integration of the ISM and MICMAC approaches to the phenomenon of SNS fatigue.

Abstract

Purpose

The Chinese construction industry is experiencing a rapid growth these days. Due to the requirements of energy conservation, emission reduction and construction waste management, the development of prefabricated buildings (PBs) has attracted much attention in the Chinese construction industry. However, the development of PBs are still in their infancy in China, which have been negatively impacted by many obstacles. It is of great significance to clarify and analyze these obstacles for the purpose of promoting the development of PBs in China. Due to the wideness and complex features of obstacles, the existing literature exploring the research topic lacks comprehensiveness. The purpose of this paper is to systematically identify and discuss the obstacles that hinder the development of PBs in China.

Design/methodology/approach

This paper adopts the method of news report analysis based on the news reports retrieved from China National Knowledge Infrastructure (CNKI) and nine major portals in China. The Term Frequency-Inverse Document Frequency (TF-IDF) method of content analysis was used to rank the obstacles according to their importance.

Findings

A total of 79 obstacles to the development of PBs in China are identified, and the 79 obstacles are divided into 8 dimensions. Among the Top 20 obstacles, the government dimension accounted for the highest number of 5, the market and consumer dimension and development organization dimension were 4, Manufacturing Enterprise of Prefabricated Components (PCs) dimension, construction organization dimension and design organization dimension were 2, logistics enterprise dimension was 1, and industry association dimension was 0. Among them, the biggest obstacle is the high transportation costs.

Research limitations/implications

First, data collection may not be very comprehensive. Second, this paper is only based on the obstacles in the development of PBs in China, and the universality of the management conclusions needs to be further strengthened.

Practical implications

The research results help the stakeholders in the Chinese PBs industry to better understand the barriers hindering the industry development in a systemic way, which will help propose appropriate strategies to address these barriers.

Originality/value

This paper clarifies the obstacles of China's PBs and makes an analysis, which is of great value to the development of China's PBs.

Abstract

The major component of agriculture production includes the type of seed, soil, climatic conditions, irrigation pattern, fertilizer, weed control, and technology used. Soil is one of the prime elements in modern times for agriculture. Soil is also one of the primary and important factors for crop production. The available soil nutrient status and external applications of fertilizers decide the growth of crop productivity (Annoymous, 2017). The upcoming research question that needs to be addressed is What is the application of soil data on soil health management for sustaining agriculture? Driven by the need, the aim of the present study is (a) to explore the soil parameters of a district, (b) compare the values with the standards, and (c) pave a way for mapping the crops with suitability of soil health. This study will not only be beneficial for the district to take appropriate steps to improve the soil health but also would help in understanding the causal relationship among soil health parameters, cropping pattern, and crop productivity.

Abstract

China has a bad reputation — justified or not — for corruption: in a recent Transparency International survey, it was listed by US and European businesspeople as one of the three most corrupt countries in Asia, though its ranking fell slightly in 1996. A national survey revealed that ordinary Chinese regard corruption as the most serious problem after inflation, though 52 per cent expressed doubt that the Government could do anything about it. In 1995, in Beijing alone, 1,085 cases of corruption were uncovered. In 1996, in the Working Report of the Supreme Peoples's Procuratorate, the Chief Procurator Zhang Siqing observed:
