Abstract

Purpose

The purpose of this research is to examine the effect of temporal landmarks on positive illusions and the downstream implications of this effect on consumer preference for new products with functional risks.

Design/methodology/approach

Study 1 adopted a single factor (temporal landmarks: beginning vs ending) between-subjects design. Study 2 adopted a 2 (temporal landmarks: beginning vs. ending) × 2 (salience of the temporal landmark: salient vs not salient) between-subjects design. Study 3 used a single factor (temporal landmarks: beginning vs ending) between-subjects design.

Findings

Through three studies, we show that the ending temporal landmarks reduce positive illusions (Studies 1 and 2). The underlying process is enhanced perceptions of psychological resource depletion (Study 3). The authors further show that decreased positive illusions lead consumers to less prefer new products with functional risks (Study 3).

Originality/value

Existing studies on temporal landmarks have exclusively focused on the beginning landmarks and account for its effects from a motive perspective. In contrast, the authors take a look at the ending landmarks and identify perceptions of psychological resource depletion as the underlying process, which suggests a new angel understand how temporal landmarks influence individuals' cognitions and behavior.

Abstract

Purpose

This study aims to monitor and guide the assembly process. The operators need to change the assembly process according to the products’ specifications during manual assembly of mass customized production. Traditional information inquiry and display methods, such as manual lookup of assembly drawings or electronic manuals, are inefficient and error-prone.

Design/methodology/approach

This paper proposes a projection-based augmented reality system (PBARS) for assembly guidance and monitoring. The system includes a projection method based on viewpoint tracking, in which the position of the operator’s head is tracked and the projection images are changed correspondingly. The assembly monitoring phase applies a method for parts recognition. First, the pixel local binary pattern (PX-LBP) operator is achieved by merging the classical LBP operator with the pixel classification process. Afterward, the PX-LBP features of the depth images are extracted and the randomized decision forests classifier is used to get the pixel classification prediction image (PCPI). Parts recognition and assembly monitoring is performed by PCPI analysis.

Findings

The projection image changes with the viewpoint of the human body, hence the operators always perceive the three-dimensional guiding scene from different viewpoints, improving the human-computer interaction. Part recognition and assembly monitoring were achieved by comparing the PCPIs, in which missing and erroneous assembly can be detected online.

Originality/value

This paper designed the PBARS to monitor and guide the assembly process simultaneously, with potential applications in mass customized production. The parts recognition and assembly monitoring based on pixels classification provides a novel method for assembly monitoring.

This study aims to explore Asian American students’ identities and their perceptions about who they are within the Midwestern American high school setting.

Abstract

Purpose

This study aims to explore Asian American students’ identities and their perceptions about who they are within the Midwestern American high school setting.

Design/methodology/approach

A naturalistic inquiry (Lincoln and Guba, 1985) is employed in this qualitative study. Naturalistic inquiry assumes that reality is constructed by individuals, and there exist multiple realities as diverse people experience teaching and learning (Glesne, 1999). It is characterized by natural settings (the schools), natural language (language actually used by students and teachers), responsiveness to concerns and issues of stakeholders (what is important to students and teachers) and collaborative checks on trustworthiness.

Findings

The study finds that the participants all identify themselves as students, while they perceive differently on their racial/ethnic and cultural identity. They have employed a variety of strategies to negotiate with their dynamic, multiple and sometimes contradictory identities when confronted with challenges and opportunities within different social contexts.

Research limitations/implications

The limitations of my study lie first in a small number of participants. Eight Asian American students do not represent the heterogeneous Asian American groups in the USA. More students would provide different perspectives and experiences in the study. The time for conducting this study is another limitation. Longer period on the research sites would provide thicker descriptions.

Practical implications

There are implications for educational practice and future research to help understand the diversity among Asian American students and to find ways to integrate accurate and comprehensive information related to Asian Americans into the curricular with critical reflection upon the issues of race, ethnicity, culture and identity.

Originality/value

This study will enrich the current literature on Asian American education because there is currently limited research in this area. It will give voices to Asian American students and contribute to a better understanding of how both students and teachers are responding to the challenges faced in many schools as demographics change. It will also have implications for teacher education and encourage awareness in this field that might affect future educational practices and policies.

Abstract

Purpose

The purpose of this paper is to highlight the significance of relationship quality factors (customer satisfaction, e‐trust, and e‐commitment) on positive word of mouth (WOM) in online retailing.

Design/methodology/approach

The relative importance of site characteristics in online retailing on customer satisfaction was examined and the relationship among customer satisfaction, trust, and commitment in offline was identified. This paper then proposes a conceptual model of the relationship among site characteristics, relationship quality, and WOM in online retailing. AMOS 5.0 was used to test for the hypothesized relationships.

Findings

All of site characteristics in online retailing have a positive influence on customer satisfaction. Communication of site characteristics has a positive effect on customer satisfaction more than the other factors (shopping convenience, site design, informativeness, and security). Customer satisfaction affects positively e‐commitment more than it does e‐trust. E‐commitment affects positively WOM more than it does e‐trust. This paper identifies the causal relationship among site characteristics, relationship quality, and WOM. Further, the relative importance of customer satisfaction in relationship quality of online retailing is examined.

Originality/value

Results provide important insights into the impact of site characteristics in online retailing on customer satisfaction compared to other previous researches. In addition, e‐trust and e‐commitment are identified as important antecedents of e‐WOM.

Abstract

Purpose

The purpose of this paper is to add expanded perlite (EP) immobilized microorganisms that replace part of the standard sand in mortar to improve the self-healing ability of mortar cracks and reduce the water absorption of mortar after healing.

Design/methodology/approach

Bacillus pseudofirmus spores were immobilized with EP particles as self-healing agents. The effects of adding self-healing agents on the compressive strength of mortar specimens were observed. The ability of mortar specimens to heal cracks was evaluated using crack microscopic observation and water absorption experiments. The filler at the cracks was microscopically analyzed by scanning electron microscope and X-ray diffraction experiments.

Findings

First, the internal curing effect of EP promotes the hydration of cement in mortar, which generates more amount and denser crystal structure of Ca(OH)2 at mortar cracks and improves the self-healing ability of mortar. Second, the self-healing ability of mortar improves with the increase of self-healing agent admixture. Adding a self-healing agent of high admixture makes the planar undulation of calcite crystal accumulation at mortar cracks more significant. Finally, the initial crack widths that can be completely healed by adding EP and self-healing agents to the mortar are 200 µm and 600 µm, respectively.

Originality/value

The innovation points of this study are as follows. (1) The mechanism of the internal curing effect of EP particles on the self-healing ability of mortar cracks was revealed by crack microscopic observation tests and microscopic experiments. (2) The effect of different self-healing agent amounts on the self-healing ability of mortar cracks has been studied. (3) The effects of EP particles and self-healing agents on healing different initial widths were elucidated by crack microscopic observation tests.
