Abstract

Purpose

This paper aims to focus on the variable stick force-displacement (SFD) gradience in the active side stick (ASS) servo system for the civil aircraft.

Design/methodology/approach

The problem of variable SFD gradience was introduced first, followed by the analysis of its impact on the ASS servo system. To solve this problem, a linear-parameter-varying (LPV) control approach was suggested to process the variable gradience of the SFD. A H robust control method was proposed to deal with the external disturbance.

Findings

To validate the algorithm performance, a linear time-variant system was calculated to be used to worst cases and the SFD gradience was set to linear and non-linear variation to test the algorithm, and some typical examples of pitch angle and side-slip angle tracking control for a large civil aircraft were also used to verify the algorithm. The results showed that the LPV control method had less settling time and less steady tracking errors than H control, even in the variable SFD case.

Practical implications

This paper presented an ASS servo system using the LPV control method to solve the problem caused by the variable SFD gradience. The motor torque command was calculated by pressure and position feedback without additional hardware support. It was more useful for the electronic hydraulic servo actuator.

Originality/value

This was the research paper that analyzed the impact of the variable SFD gradience in the ASS servo system and presented an LPV control method to solve it. It was applicable for the SFD gradience changing in the linear and non-linear cases.

Abstract

Purpose

This qualitative study aimed to explore how the school–university partnership (SUP) enhances the elementary teachers' professional development in a school-based setting.

Design/methodology/approach

By following the qualitative case study methodology, this case study employs semi-structured interviews (the authors designed) with 10 school teachers and administrators. The authors adapted the iterative process analysis (Miles and Huberman, 1984) for compiling, coding, annotating the data and interpreting the interview transcripts. The authors also used the member checking technique that establishes credibility in a qualitative study (Lincoln and Guba, 1985) with six participants.

Findings

The findings suggest that participating in a series of professional learning activities led to the enhancement of teachers' and administrators learning experiences in view of educational theories, action research abilities, teaching efficiency, teaching research capacities and improvement of school guidelines. Further, they reveal that the participants' expectations for future SUP collaborations centred on realizing the sustainability and effectiveness of collaborations, and autonomy of teachers.

Research limitations/implications

The limitations of the current study include its focus on a single SUP within one school and the reliance on data collected only by interviews during the SUP process. This study offers implications for teacher learning within SUP collaborations. First, schools should consider how to involve and influence all teachers rather than SUP core members only. To this end, authentic professional learning communities need to be constructed. Second, universities should pay much more attention to the professional development of their faculty members towards integration of theoretical knowledge and practical experiences.

Originality/value

This original study explores practical ways of improving teachers' theoretical and practical teaching practices/experiences through SUP projects, and contributes new knowledge to the teaching professional development of school teachers and administrators.

Abstract

Purpose

Though daycare centres are built to facilitate children's social and physical growth, divergent stakeholder perceptions yield conflicts while managing risks for each space due to the minimal guidelines in the Republic of Korea. Due to the unclearly defined knowledge and experience gap between representative stakeholders, teachers have difficulties in operating it with high satisfaction. This study therefore was conducted to systematically identify which parts of performance should be increased to preferentially increase end-user satisfaction in limited resources.

Design/methodology/approach

This research conducted quantitative analysis gradually. Importance–performance analysis (IPA) grasped the perceptions of construction practitioners and end-users after identifying space composition and representative risks of daycare centres. Based on the factors influencing perception differences, principal component analysis and structural equation modelling (SEM) were conducted to determine which space improves the performance preferentially to increase overall end-user satisfaction.

Findings

As the utilisation of indoor spaces increases after COVID-19, improvement of indoor spaces except for indoor playroom is necessary, especially, advancement of the quality of teachers' rooms.

Practical implications

Outputs by reflecting the end-user experiences support to understand which spaces are managed from the limited resources.

Originality/value

Theoretical framework for daycare centre was established in Korea where guidelines were insufficient, and differences in perception of each risk of stakeholders were identified. Moreover, gradual statistical analysis was set to construct end-user-focused centres by extracting where the performance of space should be improved in prior.

Abstract

Purpose

In the current business environment, no organization is assured of survival without continuous innovation. Employees’ innovative behavior is critical to enhance the innovation of an organization. While most literature on innovative behavior has focused on employees in the private sector, the purpose of this paper is to explore the factors that affect innovative behaviors in the government sector. In particular, it examines how proactivity, leader-member exchange (LMX), and climate for innovation affect employees’ innovative behavior in the Korean government sector, which is generally characterized as highly hierarchical, structured, and formalized.

Design/methodology/approach

The authors selected a sample of government employees in the Ministry of Education in Korea. Through the researchers’ contacts, ten government agencies agreed to recruit their employees to participate in the study. Data from 1,011 respondents were analyzed in two steps using structural equation modeling. First, to examine the construct validity of the measures, the authors examined the measurement model using the confirmatory factor analysis. Second, the interrelationships among the four variables were assessed. The hypothesized structural model was examined and compared to several alternative models to explore the best model fit to the data. The authors then examined the regression coefficients to determine the hypothesized relationships in the final structured model.

Findings

The results revealed the following: proactivity and climate for innovation had positive relationships with innovative behavior; LMX had a positive relationship with proactivity although it did not have a direct relationship with innovative behavior; and organizational climate for innovation did not ensure proactivity of employees.

Originality/value

The antecedents included in this research have been studied in relation to innovative behavior in several studies, but studies have called for further study. Few studies have examined innovative behavior in the public sector and they have examined innovation in the public sector which has mostly been focused on environmental factors surrounding government organizations or policy choices of government leaders while ignoring the individual traits of public workers, relational dynamics among people, and the cultural aspects of the organizations. This study investigated the interrelationships among the antecedents in the process of impacting innovative behavior in the public sector in Korea. In addition, little research has examined the antecedents of innovative behavior together. This study expands our knowledge of the roles and interrelationships of proactivity, LMX, and organizational climate for innovation as they relate to innovative behavior.

Abstract

This paper explores the major factors influencing multinational companies’ (MNCs) propensity to change the level of resource commitments during financial crises in emerging markets. Favorable changes in the host government policies, market demand, firm strategy, and infrastructural conditions are hypothesized to influence the MNCs’ decision to increase resource commitments during a crisis. The hypotheses are tested with data collected in a survey of 82 MNCs during the recent Argentine financial crisis (late 2002). While all the above variables are considered by the respondents as generally important reasons for increasing resource commitments during a crisis, only favorable changes in government policies significantly influence MNCs’ decisions to change the level of resource commitments during the Argentine financial crisis. The research, managerial implications, and policy‐making implications are discussed.

Abstract

China is currently developing and promoting an industrial cluster policy at the government level. By enacting the ‘Opinion on promoting industrial cluster development’, China is supporting the development of industrial clusters. Building an industrial cluster is done by using a single factor but requires many additional factors like regional characteristics, competitiveness factors are also diversified. To evaluate the competitiveness of the Chinese automobile industry cluster, a competitiveness element index should be developed and a competitiveness evaluation method is needed to evaluate the importance of each element. To accomplish this objective, this research applied the analytic hierarchy process (AHP) and focused on the importance of the competitiveness elements.

This research investigated the character is tics regarding cases of clusters and also analyzed the competitiveness of the Changchun automobile cluster located in northeastern China. The purpose of this research is to help Korean enterprises who enter China in the hopes that Korea will emerge as a top automobile production country.

Abstract

Purpose

The purpose of this study is to understand the effect of different brand positions (underdog vs top dog) and comparative advertising on consumers’ brand attitudes. Additionally, this study also aims to demonstrate the effects of inspiration, self-relevance and empathy on the relationship between brand positioning and comparative advertising.

Design/methodology/approach

A two-by-three factorial design was employed with brand positions (underdog vs top dog) and three types of comparative advertising (noncomparative, indirect comparative and direct comparative) as the independent variables. Inspiration serves as the mediator, while self-relevance and empathy act as moderators and brand attitude is the dependent variable.

Findings

The results show that different brand positions significantly affect brand attitudes, with respondents having a better brand attitude toward the underdog brand. Brand attitude is partially mediated by inspiration. Self-relevance moderates the relationship between brand positioning and brand attitude. However, brand positioning, comparative advertising and empathy do not have interaction effects.

Research limitations/implications

This study contributes to a better understanding of the effect of psychological variables on brand positioning and comparative advertising.

Practical implications

The results suggest that the underdog setting requires a real and honest story because consumers will spot a fake underdog story, which will damage consumer trust in the brand and harm the brand image.

Originality/value

There is a lack of research using psychological variables to demonstrate the effect of being the underdog brand. This study contributes to the literature by employing psychological variables to illustrate the effect of underdog positioning. These findings can help brands develop branding positioning strategies.

Abstract

Purpose

To understand the unique context forming organizational learning, the current study aims to investigate the antecedents of training and development (TD) practices as an indicator of effective organizational learning from the Vietnam hospitality sector, which has not been studied rigorously.

Design/methodology/approach

This study adopts a mixed method of quantitative and qualitative data analysis, including a path analysis partial least squares structural equation modeling (PLS-SEM) based on a sample size of 354 responses and a semi-structured interview of 32 participants to test various paths predicting training effectiveness while exploring contextual differences in the Vietnam hospitality sector.

Findings

The results show that among the variables investigated, extrinsic motivation, team support and job quality were found to be significant to TD, while intrinsic motivation was found to have no significant predictive power. To explore the reasons behind these findings, the interviews indicate that the motivations of employees in the hospitality sector, most of whom are young and have a limited length of service, are highly rooted in the organization’s cultural context.

Originality/value

This study contributes to understanding the complex context of organizational learning through an investigation of an emerging economy from Southeast Asia by adding new insights into the training and motivational theories. It has practical implications for practitioners in the hospitality sector to develop more effective learning organizations during the uncertain period of this unprecedented pandemic.

Abstract

Since the declaration of reform and market opening from China in 1990, China has drawn much attention from the world thanks to its rapid economic growth and its emergence as the world's major consumer market and the center of the global economy. Moreover, it established the new trade order, making East Asia the center of the new trade trend as it becomes a manufactural and sales stronghold of multinational companies. The Chinese distribution market is expected to show a high growth rate by 2010 and it draws attention as a new business sector which can bring huge profits. However, advancement of the Chinese distribution industry now faces systemic problems and research on such problems is insufficient. Therefore, in this study we will conduct SWOT analysis based on previous studies on the Chinese distribution industry and use it as a ground to propose strategic solutions for development.
