Abstract

The HITSAT‐1 is the first small satellite developed by Harbin Institute of Technology (HIT) whose mission objective is to test several pivotal techniques. In the initial orbit period, the satellite is likely to tumble as the result of separating from the rocket. How to capture it promptly with finite magnetic torque is an important problem. In this paper, considering the restrictive conditions of the magnetic field, the variable structure control theory is used to cope with the magnetic torque. Because of using the reaction wheels and magnetorquers as the control actuators, the combination control algorithm has been adopted in the initial orbit period. The results of the computer simulation indicated that the algorithm has excellent robustness and can be designed and realized easily.

Abstract

Purpose

Currently, lubrication analysis of piston ring is generally done under engine rated operating condition. However, the engine (such as the vehicle engine) does not always operate in rated operating condition, and its operating condition changes frequently in actual use. In addition, the lubrication status of piston ring is generally assumed as the flooded lubrication or a certain form of poor lubrication in most of the lubrication analysis.

Design/methodology/approach

In this paper, based on the equations about the flow rate of lubricating oil and the variation of control volume, the flow model of lubricating oil in the piston ring-cylinder liner conjunction is established. The lubrication analysis of piston ring for a four-stroke engine under different engine operating conditions is done, in which the lubricating oil at the inlet of piston ring is considered as the lubricating oil attached on the relevant location of cylinder wall after the piston ring moves over at the previous stroke.

Findings

There is remarkable difference for the lubrication characteristics of the piston ring under different engine operating conditions. The worst lubrication status of piston ring may not take place under engine rated operating condition.

Originality/value

In this paper, based on the measured engine cylinder pressure, the lubrication analysis of piston ring for a four-stroke engine under different engine operating conditions is done in which the lubricating oil supply condition at the inlet of piston ring is considered. The results of this paper are helpful for the design and research of engine piston ring-cylinder liner conjunction.

This paper aims to identify and systematically analyze the causal-effect relationships among barriers to circular food supply chains in China.

Abstract

Purpose

This paper aims to identify and systematically analyze the causal-effect relationships among barriers to circular food supply chains in China.

Design/methodology/approach

Grounded in multiple organizational theories, this paper develops a theoretical framework for identifying relevant barriers to integrating circular economy philosophy in food supply chain management. The study uses 105 responses from Chinese food supply chain stakeholders including food processors, sales and distribution channels, consumers and government officials. It applies a fuzzy decision-making trial and evaluation laboratory (DEMATEL) method to examine the causal-effect relationships among the identified barriers.

Findings

Overall, the results suggest two key cause barriers: first, weak environmental regulations and enforcement, and second, lack of market preference/pressure. Meanwhile, lack of collaboration/support from supply chain actors is the most prominent barrier. The key cause and prominent barriers are also identified for each of the supply chain stakeholder involved.

Research implications

The study offers practical insights for overcoming barriers to integrating circular economy philosophy in the management of supply chains in the Chinese food sector, as well as in other contexts where similar challenges are faced. It also sheds light on which organizational theories are most suitable for guiding similar studies.

Originality/value

To the best of the authors’ knowledge, this is the first barrier study on circular food supply chains. The use of multiple organizational theories for the development of the theoretical framework is unique in barrier studies. The study offers insights from multiple stakeholders in the Chinese food supply chains.

Abstract

Purpose

Online communities are increasingly important for organizations and marketers. However, the issue of how structural features of online communities affect consumers' behavioral engagement remains relatively unexplored. The purpose of this study is to examine how and why different types of interdependence within online communities (i.e. task/outcome interdependence) influence individual engagement in group activities, thereby providing insights regarding online community design.

Design/methodology/approach

Two surveys were conducted with two online groups in China. One is a task-interdependent group from Douban Forum, and the other is an outcome-interdependent group from Sina Forum. A total of 159 valid responses from the task-interdependent group and 162 valid responses from the outcome-interdependent group were received. We analyzed the data using multivariate regression with Smart PLS and SPSS.

Findings

The results reveal that both task and outcome interdependence are positively related to individual behavioral engagement in online group behavior, and collective efficacy mediates the aforementioned effects. In addition, task complexity moderates the relationship between task interdependence and individual behavioral engagement; communication within group moderates the relationship between outcome interdependence and behavioral engagement, and the effect is mediated by collective efficacy.

Originality/value

This study is the first to investigate the role of an important factor of group structure, namely, interdependence, in fueling individual behavioral engagement in online communities. The results shed light on companies' design strategies to develop and retain online community members and also provide important insights for researchers interested in social network marketing.

Abstract

Purpose

The purpose of this paper is to introduce a computational time dependent modeling to investigate propagation of elastic-viscoplastic zones in the shock wave loaded circular plates.

Design/methodology/approach

Constitutive equations are implemented incrementally by the Von-Kármán finite deflection system which is coupled with a mixed strain hardening rule and physical-base viscoplastic models. Time integrations of the equations are done by the return mapping technique through the cutting-plane algorithm. An integrated solution is established by pseudo-spectral collocation methodology. The Chebyshev basis functions are utilized to evaluate the coefficients of displacement fields. Temporal terms are discretized by the Houbolt marching method. Spatial linearizations are accomplished by the quadratic extrapolation technique.

Findings

Results of the center point deflections, effective plastic strain and stress (dynamic flow stress) and temperature rise are compared for three features of the Von-Kármán system. Identifying time history of resultant stresses, propagations of the viscoplastic plastic zones are illustrated for two circumstances; with considering strain rate and hardening effects, and without them. Some of modeling and computation aspects are discussed, carefully. When the results are compared with experimental data of shock wave loadings and finite element simulations, good agreements between them are observed.

Originality/value

This computational approach makes coupling the structural equations with the physical descriptions of the high rate deformation through step-by-step spectral solution of the constitutive equations.

Abstract

Purpose

This paper aims to investigate the average daily consumption of cigarettes and its correlates, attitudes toward smoking, and suggestions for anti‐smoking measures in a sample of Chinese college student smokers.

Design/methodology/approach

A sample of 150 college student cigarette smokers in Baoding, a city near Beijing, filled out a questionnaire asking about their average daily consumption of cigarettes, attitude toward smoking and their opinions on how they might control their smoking behavior.

Findings

In total, 85.3 percent of the smoking students were males and 14.7 percent females, and males had started smoking earlier. However, and surprisingly, the average daily consumption among females was greater than among males (9.6 vs 5.6 cigarettes a day, p<0.01). Average daily cigarette consumption was significantly associated with perceived health condition (students who thought themselves in poorer health consumed more), perceived risk of cigarette smoking (but with those who thought it harmful actually consuming more than those who did not), frequency of offering cigarettes as gifts, and perceived enjoyment from smoking. The three most commonly reported measures which curbed smoking were friends' or classmates' suggestions, the urging of a boyfriend/girlfriend, and the urging of parents.

Practical implications

Findings in this paper underscore the importance of developing effective smoking cessation programs through gender‐specific approaches at post‐secondary educational institutions as well as coordinating anti‐smoking efforts at multiple levels of educational administration in China.

Originality/value

This paper adds to the few studies on Chinese college students' cigarette smoking practices and student smokers' attitudes toward cigarette smoking. It also reports for the first time possible effective anti‐smoking measures as suggested by the students themselves. The value of this study lies in the finding that cigarette smoking among highly educated individuals in China is on the rise and vigorous research on the smoking behavior of this group should be a high priority.

Abstract

Purpose

The purpose of this study is to assess the impact of land rights and tenure types on farmers' investment behavior in Chinese collective forests, using household survey data from Fujian Province.

Design/methodology/approach

In this study, the authors conducted a household survey in Fujian province of 520 randomly selected forest farmers. The authors used a random‐effects Tobit model to estimate the impact of land rights and other components on, for example, tenure security and harvest quota, and the impact of tenure types on farmers' investment incentives.

Findings

This study produced three main findings: perceived tenure security in the context of frequent agricultural land redistribution negatively affects input intensity; farmers still perceive some tenure arrangements to be more uncertain than others, which discourages them from undertaking investments on such plots; and the harvest quota regulation, introduced to conserve forest stock, has in fact acted as a disincentive in forestry management.

Originality/value

Almost all previous studies are based on national or regional data, which have primarily focused on the links between tenure types and investment incentives. In this study, based on the plot‐level data, the authors are able to assess not only the impacts of tenure types but also how specific land rights and their components affect farmers' investment behavior.

Abstract

Purpose

The goal of the special issue is to review current cigarette smoking trends in China; this article aims to provide an overview of the main themes of the special issue.

Design/methodology/approach

The instruments for data collection of the five studies in this special issue are surveys. One study used a random sampling method, one used an intercept survey method, and three used a convenience sampling method.

Findings

Highlights of the findings include: among the 677 physicians surveyed, 31.6 percent of the men and 0.9 percent of the women were current smokers; 79.2 percent of the cigarette users reported smoking on duty; 15 percent of the cigarette users smoked in front of patients. Sixty‐one percent of the physicians often advised patients to quit smoking. Two factors significantly influenced a physician's anti‐smoking frequencies: whether they were smokers themselves and whether they had received training on helping patients to quit smoking. About half of the 269 patients surveyed reported seeing someone smoking inside the hospital, and 22.3 percent had seen physicians and/or nurses smoking. Among the 758 medical students surveyed, 26.5 percent of males and 1.6 percent of females had smoked in the previous 30 days.

Practical implications

The exclusive coverage of a western journal on cigarette smoking in China can draw the attention of Chinese and western scholars in the field, as well as the attention of the Chinese Ministry of Health, to this major national problem. This attention should help to advance anti‐smoking educational campaigns in China.

Originality/value

This is the first special issue by a western academic journal on cigarette smoking in China, where rates are far higher than in most other parts of the world, and are a major health concern. Two studies have large sample sizes and all five studies have high response rates.

Abstract

The growing impact of women in the workforce has kept the leadership style of women on the research agenda. Reviews some of the current thinking on women and leadership, drawing on general and educational management literature. Particular attention is paid to management in education because of: the continued pressure on the higher educational sector generally to be publicly accountable that indicates a specific need for effective leadership; the fact that at the school level, leadership is a central theme in the literature on organizational improvement and educational reform; and education is a field numerically dominated by women, yet despite some evidence of a growing willingness of women to take up leadership positions in the field, educational leadership is still a male preserve. Concludes with a synopsis of some of the factors that may account for differences in leadership style.
