Methods: Male and female (n = 197) college basketball players completed the Psychological Performance Inventory-Alternative (PPI-A), a measure of characteristics and skills consistent with mental toughness, and the PERK an objective measure of basketball performance. Results: Findings suggest that basketball performance can be partially predicted by mental toughness and starting status. Males reported greater mental toughness than females. Starters and nonstarters did not differ in mental toughness. Moderated hierarchical regression analysis indicated that mental toughness was related to performance for male players as both a main effect and interaction with starter status. For female players, in contrast, starter status was the only significant predictor of performance. Practitioners are encouraged to foster the psychological skills associated with mental toughness in females and non-starters in basketball. Conclusion: Discussion of the PPI-A as a measure of mental toughness and suggestions for its improvement are explored. A need exists for additional research on mental toughness and objective performance, as performance enhancement is a major impetus for research on mental toughness.

At the same time literature in port economics and management has proposed various means for analyzing market conditions, overcoming competitive pressures in the port industry and pursuing sustainable competitive advantage. In line with this discussion, albeit with a significant time delay, port economics and management literature has also proposed the use of marketing strategies as a strategic tool towards achieving port competitiveness. However, the early approaches to port marketing, mainly based on consumer marketing principles, where followed by scarce references, mainly dealing with particularities of marketing implementation in ports and terminals. This paper attempts to provide a solid theoretical background to the notion, the need and the applicability of the marketing concept in the container port industry. It investigates the preconditions under which port marketing strategies are designed and formulated, by measuring the level of market orientation of ports and terminals. Furthermore, it attempts to examine the impact of market orientation on port performance, under the mediating role of marketing tactics and the moderating effect of the ports'/terminals' internal and external environment.展开更多
