In order to reduce avoidably lengthy duration required to test highly reliable products under usage stress, accelerated life test sampling plans (ALTSPs) are employed. This paper aims to build a decision model for obtaining optimal sampling plan under accelerated life test setting using Type-I hybrid censoring scheme for products covered under warranty.

The primary decision model proposed in this paper determines ALTSP by minimizing the relevant costs involved. To arrive at the decision model, the Fisher information matrix for Type-I hybrid censoring scheme under accelerated life test setting is derived. The optimal solution is attained by utilizing appropriate techniques following a nonlinear constrained optimization approach. As a special case, ALTSP for Type-I censoring is obtained using the same approach. ALTSP under Type-I hybrid censoring using the variance minimization approach is also derived.

On comparing the optimal results obtained using the above mentioned approaches, it is found that the cost minimization approach does better in reducing the total cost incurred. Results also show that the proposed ALTSP model under cost function setting has considerably lower expected testing time. Interesting findings from the sensitivity analysis conducted using a newly introduced failure dataset pertaining to locomotive controls are highlighted.

The research introduces a model to design optimum ALTSP for Type-I hybrid censoring scheme. The practical viability of the model makes it valuable for real-life situations. The practical application of the proposed model is exemplified using a real-life case.

The overall goal of science is to build a valid and reliable body of knowledge about the functioning of the world and how applying that knowledge can change it. As personnel and human resources management researchers, we aim to contribute to the respective bodies of knowledge to provide both employers and employees with a workable foundation to help with those problems they are confronted with. However, what research on research has consistently demonstrated is that the scientific endeavor possesses existential issues including a substantial lack of (a) solid theory, (b) replicability, (c) reproducibility, (d) proper and generalizable samples, (e) sufficient quality control (i.e., peer review), (f) robust and trustworthy statistical results, (g) availability of research, and (h) sufficient practical implications. In this chapter, we first sing a song of sorrow regarding the current state of the social sciences in general and personnel and human resources management specifically. Then, we investigate potential grievances that might have led to it (i.e., questionable research practices, misplaced incentives), only to end with a verse of hope by outlining an avenue for betterment (i.e., open science and policy changes at multiple levels).

This study aims to systematically review a total of 513 papers using experimental methods in hospitality and tourism research and then proposed new recommendations to address approaches that have been confusingly adopted or ignored in the current literature.

An extensive literature review was conducted. Together with critiques on previous studies, four recommendations were proposed to help carry out future experimental studies using more rigorous and exact approaches.

Multiple experimental studies can provide stronger evidence for theoretical arguments. Demonstration of the theoretical underlying mechanism using evidence based on mediation and moderating methods is required. The adoption of complementary methods can mitigate the generic weaknesses of experimental methods. In addition, enhancement of the realism of experiments is required to obtain stronger empirical evidence with internal and external validity.

This study proposes four constructive recommendations which help researchers to conduct future experimental design studies correctly. Valid and exact research outcomes can help practitioners to carry out new useful marketing strategies.

After reviewing 513 previous papers that used experimental design in the hospitality and tourism fields, this study proposes four new recommendations to facilitate a better understanding of experimental design. The original and innovative nature of this study will help future investigations to adopt more accurate statistical approaches.

A majority of consumers are supportive of socially responsible companies making positive contributions to their communities. However, results of empirical studies on consumers’ attitudes toward corporate social responsibility (ACSR) and their purchasing intentions (PI) have been inconsistent. The purpose of this paper is to measure the strength of association between ACSR and PI. This study also aims to examine the moderating effects of firm characteristics (product type and commitment to green/sustainability initiatives), consumer demographics (gender and age) and external factors (geographic region).

The authors conducted a systematic search, which yielded 28 studies that met the criteria for inclusion in the meta-analysis (total participants = 12,242). This study used meta-analysis to examine the association between ACSR and PI using random effects analyses. Subgroup analyses and meta regression were used to detect moderators in the meta-analysis.

The main result showed that the average weighted correlation (r+) was 0.478, indicating that ACSR had a strong positive relationship with PI. Subgroup analyses indicated geographic region and product type had no significant moderating effect on the relationship between ACSR and PI. However, the difference for commitment to green initiatives was marginally significant. The high levels of heterogeneity (Q = 535.199, I² = 94.955) and a possible absence of publication bias were evident in the meta-analysis.

This meta-analysis can make meaningful contributions to the existing body of knowledge on corporate social responsibility by testing the influence of the important moderators that include geographic region, product type and commitment to green initiatives.

Early career teachers (ECTs) of Color are key in making change, resisting racism and pushing back against white supremacy in K-12 education, specifically in English Language Arts (ELA) classrooms. Through a narrative telling inquiry (Clandinin and Connelly, 2000) of Nora, an Asian American ELA ECT in the Midwest, and by drawing on Fisher’s (2011) Critical Integral Pedagogy of Fearlessness, this study aims to recognize the narrative power within teaching praxis as Nora stories herself toward becoming a critical pedagogue.

Using narrative inquiry methodology and methods (Clandinin and Connelly, 2000), the authors simultaneously considered the commonplace tenets of narrative inquiry – temporality, sociality and place – of the intertwined relationships of the participants and observers. The field texts included in the corpus of data include myriad tellings of Nora’s experiences in her initial years of teaching ELA. Data were analyzed in stages of parsing out narrative blocks and structures.

The findings indicate that Nora, as an ECT, went through recursive cycles of fear as conceptualized by Fisher (2011) – bravery, courageousness and being fear-less – of working toward radical love (Hooks, 2000) within her ELA instruction. The authors argue that Nora confronted her personal and professional fears as she strove to become a critical pedagogue in her ELA classroom.

Current scholarship portrays ECTs as lacking agency in their development and/or effectiveness in the classroom and little is said about Asian American ELA ECTs and critical instruction. The authors present Nora’s counter-narrative to make visible what is right with ELA ECTs, specifically teachers of Color, as they transform their fear into courage to fight for educational equity.
