Based on the socioemotional selectivity theory, this study aims to explore the differential influences of control and commitment human resource (HR) practices on employee job crafting as well as the mediating role of occupational future time perspective (OFTP).

This study used a two-wave design to survey 53 HR managers and 339 employees of 53 Chinese firms. The hypotheses were tested by conducting multilevel structural equation modeling in Mplus 7.4.

The results show that control HR practices are negatively related to job crafting, while commitment HR practices are positively related to job crafting. Further, control HR practices are negatively associated with the remaining opportunities dimension of OFTP, whereas commitment HR practices are positively associated with remaining opportunities. However, both types of HR practices have no significant relationship with the remaining time dimension of OFTP. Finally, remaining opportunities mediate the relationships between both types of HR practices and job crafting.

Managers should be aware of how to promote or inhibit employee job crafting by implementing different HR practices.

This study contributes to the job crafting research by demonstrating that the relationship between HR practices and job crafting depends on the type of HR practices in use, as well as contributing to OFTP research by showing that different types of HR practices have differential relationships with the remaining opportunities dimension of OFTP.

Scholars have examined the relationship between sports and urban development and proposed to use sport programs and events as a catalyst to revitalize communities, upgrade urban infrastructure, promote city image, shift economic structure, nurture an active lifestyle, and enhance societal harmony and solidarity. Yet, previous studies were usually focused on mega sport events and were typically conceptual, theoretical and lack of practical applications. This study was designed to attain in-depth understanding on how a specific sport, table tennis, can be systematically organized and utilized to influence urban development through a qualitative research injury.

This investigation was carried by conducting in-depth interviews of the executive director of the Shanghai Table Tennis Association, on-site observations and comprehensive review of literature. Development of interview questions took into consideration the conceptual framework postulated by Preuss (2007) that contains six structures of urban development through sports. Triangulation analyses were conducted to cross validate the three information sources to generate themes and assertions.

While the identified practices were consistent with Preuss' (2007) framework, specific management activities earnestly practiced in Shanghai are centered on utilizing cultural and historical heritage, star power, branding strategies, staging tournaments, hallmark events, technical innovation and government relations to achieve the objectives of table tennis as a sport and the objectives of urban development through table tennis.

The findings of this study help fill the void that a theory usually cannot specify, namely, detailed, unambiguous practices. While table tennis may be a viewed as a small sport in many parts of the world, it has a strong, unprecedented historical heritage in Shanghai. This city has made a prudent choice and investment in this sport, which has proved to be effective. Other cities in the world should look into their own social, cultural and historical heritage and develop sport strategies, operations and programs accordingly.

This paper aims to implement quality of service(QoS) dynamic optimization for the integrated satellite-terrestrial network(STN) of the fifth-generation Inmarsat system(Inmarsat-5).

The structure and operational logic of Inmarsat-5 STN are introduced to build the graphic evaluation and review technique(GERT) model. Thus, the equivalent network QoS metrics can be derived from the analytical algorithm of GERT. The center–point mixed possibility functions of average delay and delay variation are constructed considering users' experiences. Then, the grey clustering evaluation of link QoS is obtained combined with the two-stage decision model to give suitable rewards for the agent of GERT-Q-learning, which realizes the intelligent optimization mechanism under real-time monitoring data.

A case study based on five time periods of monitoring data verifies the adaptability of the proposed method. On the one hand, grey clustering based on possibility function enables a more effective measurement of link QoS from the users' perspective. On the other hand, the method comparison intuitively shows that the proposed method performs better.

With the development trend of integrated communication, STN has become an important research object in satellite communications. This paper establishes a modular and extensible optimization framework whose loose coupling structure and flexibility facilitate management and development. The grey-clustering-based GERT-Q-Learning model has the potential to maximize design and application benefits of STN throughout its life cycle.

A novel compound was synthesized by cyclohexylamine, acetophenone and cinnamaldehyde through Mannich reaction in laboratory to use as corrosion inhibitor for steel in acidification process.

The corrosion and inhibition of 13Cr stainless steel in conventional acidification solution were investigated by electrochemical measurements and soaking experiments. The corrosion appearance was observed with scanning electron microscope on the whole surface of 13Cr stainless steel in 20% HCl solution, and the protection film was confirmed on the surface in presence with inhibitor.

Results manifested that the inhibitor C23H27NO can effectively inhibit the corrosion reaction by forming an adsorption layer function as a barrier. Polarization curves indicated that the mixed inhibitor can reduce anodic dissolution and cathodic hydrogen evolution reactions simultaneously. The results of impedance measurements indicated that this inhibitor cannot change the corrosion mechanism of 13Cr stainless steel in 20% HCl solution. The results of the study can provide a theoretical basis for the application of 13Cr stainless steel in conventional acidification solutions during oil well acidification construction process.

A novel compound was synthesized by cyclohexylamine, acetophenone and cinnamaldehyde through Mannich reaction in laboratory to use as corrosion inhibitor for steel in acidification process. The corrosion and anti-corrosion mechanism of 13Cr steel in acid solution was proposed.

The core of the micro–macro paradigm of mainstream Western economics is the assumption that a rational economic man with complete freedom of economic behaviors living in a fully competitive, free-market economy pursues maximum personal benefits. The purpose of this paper is to show the reasons for failure of mainstream Western economics explaining the “mystery of China’s economic growth” and the necessity of understanding the mystery from the paradigm of realm economics.

The system of socialism with Chinese characteristics led by the Communist Party of China (CPC) and the local governments that play a crucial role in the reform and opening-up has the realm attribute. It is necessary to develop a new paradigm for realm economic analysis and promote the creation of new economic globalization and international political and economic order.

According to the fourth plenary session of the 19th CPC Central Committee, “Since the New China was founded 70 years ago, our Party has led our people to create the rarely-seen miracle of rapid economic development and miracle of long-term social stability”. The authors find that it is effective and necessary to explain the miracle of China’s economic growth from the paradigm of realm economics.

As proven by practice, the system of socialism with Chinese characteristics and the governance system of China are guided by Marxism, rooted in China with a deep Chinese cultural foundation, and sincerely supported by the people.

This study aims to delve upon customer satisfaction and service quality within small- and medium-sized hotels (SMSHs) by using a modified SERVQUAL model.

Data for the study were collected from a sample of 253 guests of varying nationalities who stayed at SMSHs of one-to-three-star ratings in the UAE. Moreover, 15 face-to-face interviews were conducted. The influence of the five dimensions of the SERVQUAL model on visitors’ satisfaction was explored using structural equation modelling.

The results indicated that three out of the five dimensions of SERVQUAL, namely, tangible, responsiveness and assurance, have significant positive impact on visitors’ satisfaction of the SMSHs Industry. The remaining two dimensions of SERVQUAL, reliability and empathy, have no significant impact on visitors’ satisfaction.

This study provides a major contribution in that it offers the potential to examine a vastly under researched area of customer satisfaction and service quality of SMSHs in a developing country.
