Abstract
Purpose
Changes are required to improve the performance of Sharia banking in Indonesia. Using dynamic capability theory, this study aims to analyze organizational learning, change process and change context (OCC) in Bank Syariah Indonesia as influenced by market orientation (competitor and customer orientation) and moderated by religiosity and its impact on organizational performance (Maqashid Sharia) using a multilevel perspective.
Design/methodology/approach
To test the hypothesis, this research surveyed by distributing online questionnaires to managers and employees at 62 branch offices of Bank Syariah, the largest Sharia bank in Indonesia. Data processing involved multilevel structural equational modeling with Mplus analysis software.
Findings
Market orientation determines an organization’s ability to change significantly, which leads to organizational performance being significantly moderated by religiosity. In OCC, organizational learning influences change context through change processes, ultimately influencing organizational performance (Maqashid Sharia).
Originality/value
This research used a multilevel perspective by combining market orientation and OCC variables moderated by religiosity and its impact on Maqashid Sharia. This study was conducted at the largest Sharia bank in Indonesia, Bank Syariah Indonesia.

Abstract
Purpose
This paper aims to focuses on by investigate the heat transmission and free convective flow of a suspension of nano encapsulated phase change materials (NEPCMs) within an enclosure. Particles of NEPCM have a core-shell structure, with phase change material (PCM) serving as the core.
Design/methodology/approach
The enclosure consists of a square chamber with an insulated wall on top and bottom and vertical walls that are differently heated. The governing equations are investigated using the finite element technique. A grid inspection and validation test are done to confirm the precision of the results.
Findings
The effects of fusion temperature (varying from 0.1 to 0.9), Stefan number (changing from 0.2 to 0.7), Rayleigh number (varying from 103 to 106) and volume fraction of NEPCM nanoparticles (changing from 0 to 0.05) on the streamlines, isotherms, heat capacity ratio and average Nusselt number are investigated using graphs and tables. From this investigation, it is found that using a NEPCM nano suspension results in a significant enhancement in heat transfer compared to pure fluid. This augmentation becomes more important for the low Stefan number, which is around 16.57% approximately at 0.2. Secondary recirculation is formed near the upper left corner as a result of non-uniform heating of the left vertical border. This eddy expands notably as the Rayleigh number rises. The study findings indicate that the NEPCM nanosuspension has the potential to act as a smart working fluid, significantly enhancing average Nusselt numbers in enclosed chambers.
Research limitations/implications
The NEPCM particle consists of a core (n-octadecane, a phase-change material) and a shell (PMMA, an encapsulation material). The host fluid water and the NEPCM particles are considered to form a dilute suspension.
Practical implications
Using NEPCMs in energy storage thermal systems show potential for improving heat transfer efficiency in several engineering applications. NEPCMs merge the beneficial characteristics of PCMs with the enhanced thermal conductivity of nanoparticles, providing a flexible alternative for effective thermal energy storage and control.
Originality/value
This paper aims to explore the free convective flow and heat transmission of NEPCM water-type nanofluid in a square chamber with an insulated top boundary, a uniformly heated bottom boundary, a cooled right boundary and a non-uniformly heated left boundary.

This study identifies benefits and challenges of PL partnerships, and recommendations to improve the PL partnership process.
Abstract
Purpose
This study identifies benefits and challenges of PL partnerships, and recommendations to improve the PL partnership process.
Design/methodology/approach
Qualitative data was collected via semi-structured interviews (n = 8) with Irish PL retail buyers (n = 4) and producers (n = 4). Data was coded and thematically analysed.
Findings
Three key themes were identified. Theme 1 provides an overview of the benefits of PL partnerships for producers (e.g. volume driven orders, increased efficiencies) and for retailers (e.g. unique products, meeting consumer demand). Theme 2 presents challenges of PL partnerships specific to small and large producers (e.g. small producers may need significant investment to upgrade facilities, while larger producers may require significant volume to justify adaptation of production lines). Challenges common to both (e.g. risks related to short-term contracts, concerns about brand identity) are also discussed. Theme 3 summarised recommendations for successful PL partnerships generally (e.g. setting clear expectations and goals, building rapport and trust), and recommendations specific to producers and buyers specifically (e.g. producers should diversify customers to reduce risk, and retailers should communicate needs and direction).
Originality/value
There is currently limited research on PL partnerships between producers and retailers. This study addresses this gap by identifying key aspects for producers to consider when entering PL partnerships and key aspects for retailers to be aware of to help improve the attractiveness and success of these partnerships.

Abstract
Purpose
This study aims to operationalize consumer decision-making styles as higher-order constructs and investigates the influence of two distinct subdimensions of consumer vanity – namely, appearance vanity and achievement vanity – on consumer decision-making orientations (CDMO).
Design/methodology/approach
Using data from an online survey of 319 young adults, the authors construct a higher-order structural model capturing the following three orientations: social/conspicuous, utilitarian and undesirable. The partial least squares structural equation modeling approach was used to test the validity of the higher-order structural model and the hypothesized relationships.
Findings
Results, confirming the higher-order structure of consumer decision-making styles, highlight the distinctive impacts of the vanity dimensions on different CDMOs. Specifically, appearance vanity predominantly affects social and undesirable orientations, and achievement vanity influences utilitarian orientation.
Originality/value
While several theoretical classifications of consumer decision-making styles have been proposed in the past, none of the earlier studies leveraged those classifications as higher-order models. Addressing this literature gap, this study provides empirical evidence associating CDMOs with a specific consumer trait – vanity – thereby validating the higher-order nature of consumer decision-making styles.
