Purpose – The purpose of this paper is to evaluate the strengths and weaknesses of the current competitive position and performance of Indonesian Crab Industries (ICI). The paper examines whether a reorientation of the innovation strategic vision is needed to build future industrial excellence. Design/methodology/approach – Data collected from secondary sources and interviews with processors and stakeholders in the major ICI are analyzed in a five competitive forces value chain model. Findings – It is significant that the industry's competitive position and its performance in relation to international buyers is strongly related to good infrastructure and the uniqueness of the products and services it offers to buyers. Key factors related to this include: the sustainability of the raw material supply, the volume of production demanded, the manufacturing facilities and innovations and the consistency of quality. These all strengthen the value chain position. Threats from substitute products like surimi are, however, limiting the price level. The lack of market-oriented capacity to effectively develop unique products and strategies is a major barrier for entering new markets. Research limitations/implications – The interview data are based on the industry managers’ experiences as suppliers of the US market. This study may be applied as an example for analyzing market performance factors in natural resource-based industrial environments. Originality/value – The paper provides original empirical data analysis of the development and innovation strategies of the crab industries in Indonesia. It contributes to the marketing literature by linking value chain structure and industrial perception of performance drivers.

Abstract. The effect of randomness on critical behavior is a crucial subject in condensed matter physics due to the the presence of impurity in any real material. We presently probe the critical behaviour of the antiferromagnetic (AF) Ising model on rewired square lattices with random connectivity. An extra link is randomly added to each site of the square lattice to connect the site to one of its next-nearest neighbours, thus having different number of connections (links). Average number of links (ANOL) κ is fractional, varied from 2 to 3, where κ = 2 associated with the native square lattice. The rewired lattices possess abundance of triangular units in which spins are frustrated due to AF interaction. The system is studied by using Monte Carlo method with Replica Exchange algorithm. Some physical quantities of interests were calculated, such as the specific heat, the staggered magnetization and the spin glass order parameter (Edward-Anderson parameter). We investigate the role played by the randomness in affecting the exisiting phase transition and its interplay with frustration to possibly bring any spin glass (SG) properties. We observed the low temperature magnetic ordered phase (Néel phase) preserved up to certain value of κ and no indication of SG phase for any value of κ. IntroductionThe cooperative phenomena are ubiquitous in nature, driven by the presence of coupling interaction between each individual constituent of materials [1,2]. This is exemplified by the spontaneous magnetization by which certain magnetic material is entering a ferromagnetic phase below its transition temperature T c (Curie temperature) and able to attract the nearby metals surrounding it. The high temperature disorded phase and the cooperative ordered phase at low temperature are separated by T c . A phase transition is essentially rendered by the competition between the external fields, such as temperature, which tend to destroy the order and the coupling interaction which tends to create order.Based on the nature of free energy function, a phase transition is grouped into the first and the second order phase transition [3]. The transition is called as first order if the first order derivative of the free energy of the system is discontinuous. If the derivative is continuous, the transition is second order, also called continuous phase transition, at which no latent heat involved in the course of transition and no co-existing phases [2,4]. A firm example of these is the phase transition experienced by PVT systems above the critical point [5]. The phenomena nearby critical point are known as critical phenomena, and affected by limited number of controlling variables such as the type of coupling interaction, symmetry of the microscopic constituents

This paper develops a theoretical foundation for investigating effective market-oriented strategies to enable entry into new seafood markets by means of innovation and product quality advantages. The introduction of new products to the market is associated with several factors primarily including: (1) market openness and demand for new product attributes; (2) business orientation and strategies in marketing management throughout the value chain; (3) the value chain structure; (4) regulation of the value chain; (5) balances and trends in supply and demand. The relationship between these factors is understood by combining theories of Barney's VRIO concept, the five stages of Rogers' innovation-decision process model and Porter's five forces of competition position model, summarised in a market-oriented innovative quality (MOIQ) framework.

Methods of teaching reading skill are not the same in different countries. It depends on the condition and situation of the learners. Observing the method of teaching in Malaysia was the purpose of this study and the result of the study shows that there are 5 methods that are applied in classroom activities namely Grammar Translation Method (GTM), Direct Method (DM), Communicative Language Teaching (CLT), Audio Lingual Method (ALM) and Silent Way (SW). Through these methods, the students and the teacher can reach the purpose of teaching reading. From this study, it can be concluded that combining more than one method is one of the better ways for the teaching reading skill to EFL learners.
