Abstract
Purpose
This paper aims to use the Laplace Adomian decomposition method (LADM) to investigate the effects of thermal convection, thermal conduction, surface emissivity and thermal radiation on the heat dissipated by a continuously moving plate undergoing thermal processing.
Design/methodology/approach
In performing the analysis, it is assumed that the thermal conductivity and surface emissivity of the plate are both temperature-dependent. The accuracy of the LADM solutions is confirmed by comparing the results obtained for the temperature distribution within the plate with those reported in the literature based on the differential transformation method.
Findings
It is shown that the heat dissipated from the plate reduces as the Peclet number increases. By contrast, the dissipated heat increases as any one of the non-dimensionalized parameters of the system, i.e. Nc, Nr and B, increases. In addition, the temperature drop along the length of the plate reduces as parameter A increases owing to a more rapid heat transfer.
Originality/value
The results provide a useful source of reference for the choice of suitable materials and cooling fluids in a variety of practical applications.

Abstract
Using a 10,709 firm-year sample covering the 1998–2007 period, we investigate the determinants of capital structure among 1,491 ASEAN-4 (Indonesia, Malaysia, the Philippines, and Thailand) emerging market firms. Building on the work of previous authors, we apply the two-step generalized method of moments (Arellano & Bond, 1991) to develop country-specific dynamic models of target leverage decisions. The right-hand variables incorporate a lagged leverage term that controls for the firms' target adjustment process and the following four explanatory variables: firm size, profitability, tangibility, and nondebt tax shields. The sign and significance of each coefficient provides evidence regarding whether the impact of the associated variable is consistent with the trade-off or pecking order theories. We find that size is negatively associated with leverage among Malaysian, Philippine, and Thai firms but positively associated among Indonesian firms. Profitability is negatively associated with leverage among Indonesian and Malaysian firms but positively associated among Philippine firms. Tangibility is negatively associated with leverage among Malaysian firms but positively associated among Philippine firms. While the impacts of size and profitability are consistent with pecking order theory, the impact of tangibility is not supportive of a specific theory. Of the four variables, size is consistently influential, while nondebt tax shields have no significant impact among firms in any country.

Abstract
Purpose
Drawing upon an integrative perspective from intellectual capital theory with upper echelon theory, we examined how intellectual capital affects resource integration capability and subsequent strategic decision-making under weak versus strong top management team (TMT) involvement behavior. The purpose of this study was to investigate the relationships between intellectual capital and strategic decision-making and the mediated moderating effect between intellectual capital and decision-making on small- and medium-sized enterprises (SMEs).
Design/methodology/approach
Using statistical empirical analysis, we tested our research hypotheses via large-scale survey data from 323 SMEs. A regression analysis was applied to intellectual capital, resource integration capability and TMT involvement behavior to estimate their influence on strategic decision-making.
Findings
Our findings suggest that the positive effect of intellectual capital on strategic decision-making via resource integration capability is conditional on TMT involvement behavior, underscoring the role of resource integration capability and TMT involvement behavior in intellectual capital. The results also indicate that intellectual capital and resource integration capability strengthen positive decision-making relationships. Furthermore, TMT involvement behavior strengthens the positive interaction effect of intellectual capital with resource integration capability.
Practical implications
Intellectual capital is a critical and preeminent strategic resource for strengthening strategic decision-making, especially for SMEs. Notably, trends related to intellectual capital can be used to explore the management of SMEs and the corresponding contributions to and improvements in strategic decision-making. Specifically, intellectual capital can be used by SME management teams to formulate and implement relevant strategic decisions and enhance the effectiveness of decision-making, which are critical steps for success in decision-making processes.
Originality/value
This research explored the relationships among intellectual capital, resource integration capability, TMT involvement behavior and strategic decision-making in a comprehensive mediated moderation model; it is the first known study to highlight that intellectual capital can enhance strategic decision-making and provide managerial implications regarding how to align resource integration capability and TMT involvement behavior while performing strategic decision-making.
