Abstract
Purpose
To be successful in the rapidly changing global business environment, supply chains (SCs) must be agile, adaptable and aligned (Lee, 2004), a practice known as Triple-A. Therefore, the purpose of this paper is to investigate the dimensions of Triple-A SCs and their concurrent impact on all three Triple-A components.
Design/methodology/approach
The relationship among these factors is analyzed through Smart PLS-structured equation modeling (PLS-SEM) for which data have been collected from 243 SC professionals working in manufacturing organizations.
Findings
The findings of this study reveal that the relationship between visibility and adaptability are directly significant but that the negative relationship between velocity and alignment is insignificant; however, indirectly these relationships have a positive impact using the mediating effect of agility over visibility and adaptability, velocity and alignment. However, the relationship of flexibility over SC Triple-A is positively significant, visibility over agility and alignment is positively significant and velocity over agility and adaptability is also positively significant, and each impact agility over adaptability and adaptability over alignment which is significant.
Originality/value
There is a shortage of empirical studies to date that empirically provide evidence of possible relationships among Triple-A and its key dimensions when attempting to obtain Triple-A. This is the first authenticated Triple-A SC conceptual framework that provides direction to better understand the dimension and significance of Triple-A.

Abstract
Purpose
The purpose of this study is to predict the antecedents of consumers' purchase intention of energy-efficient home appliances. This study incorporated two additional constructs (knowledge of eco-labels and knowledge of eco-labels) in the model of the theory of planned behavior. Consumers' enhanced trust for energy-efficient products is crucial to purchase intention. The second construct is consumers' knowledge of eco-labels. Knowledge of eco-labels would help to assess consumers' tendency toward environmental problems and intention to purchase energy-efficient home appliances.
Design/methodology/approach
This study used a quantitative approach using a survey (questionnaire) method to collect data of respondents. Non-probability quota based on age and convenience sampling techniques were employed to select the participants of this study.
Findings
The findings of the study revealed that consumer knowledge of eco-labels, green trust, subjective norm, attitude and perceived behavioral control have positive influence on purchase intention of energy-efficient home appliances.
Originality/value
Eco-labels are served as a marketing tool to distinguish producer's products from others. Prior studies have only focused on consumers' general knowledge. This study helps marketers to understand and design strategies to generate more value for green consumers. This study also contributes to the literature on green marketing by employing the theory of planned behavior.

Abstract
Purpose
In the era of market turbulence, sourcing specialists consistently face challenges to keep the availability of the material efficiently and effectively without any disruption. Sourcing strategies and planning have a huge impact on procurement performance. The purpose of this paper is to examine the relationships among different sourcing strategies and supply risk management and performance and additionally, the role of procurement practices in different strategic settings.
Design/methodology/approach
This is empirical research that collected data gathered from 223 procurement specialists working in various manufacturing firms through a structured questionnaire. Valid data is then analyzed through the structure equation modeling technique for hypotheses testing.
Findings
The findings of this study reveal that supplier development is a partial complementary mediator between multiple supplier strategy and supply-side risk management. While in a volatile business environment, strategic supplier strategy has a significant negative impact on supply-side risk management, and in this case supplier development acts as a competing partial mediator between the two. Contract management has resulted in an important mechanism to be deployed in a strategic sourcing strategy. It is also shown that supplier risk management is also associated with improved supply management performance.
Practical implications
This paper establishes an explanation of theoretical and practical understanding of sourcing strategies and empirically shows that supplier development is the appropriate mechanism to deal with supply-side risk management, which in turn positively impacts on supplier management performance.
Originality/value
This study contributes to supply chain risk management literature, especially in the context of strategic risk management and explains how a strategic decision can impact supply risk management. This provides a piece of empirical evidence regarding the use of well-established procurement practices to improve supply performance.
