School principal emotional intelligence is necessary to enable schools being led effectively due to the changes taking place in education system lately. This study aims to explore the relationship between principal emotional intelligence and instructional leadership practices in Malaysian secondary schools. This is a non-experimental quantitative research using survey technique through the administration of a set of questionnaire that compromised demographic variables, principal emotional intelligence competency and instructional leadership practices. 396 returned questionnaires have been analyzed in this research. The findings showed that teachers perceived their principals practice high level of instructional leadership and emotional intelligence competency. Furthermore, data indicated that there was statistically significant positive correlation which is strong between principal emotional intelligence and instructional leadership practices. In addition, multiple regression analysis showed that relationship management, social awareness and self-awareness being the three emotional intelligence competencies that are statistically significant predictors of principal instructional leadership practices. The implications of this study could be used as a guide to school leaders in managing and controlling their emotions when dealing with the various parties to produce outstanding and excellence schools.

Principals and teachers are the main drivers in ensuring the quality of excellence schools. The ability of the principal to influence teachers to effectively implement the teaching process is capable of producing excellent students to achieve the goals of the school. Therefore, this study aimed to investigate the relationship between principals’ emotional intelligence in influencing teachers' self-efficacy. The research was conducted using a survey method through a questionnaire distributed to 396 teachers in Negeri Sembilan. Data analyses were performed using SPSS through Pearson r Correlation, Multiple Regression and Structural Equation Modelling (SEM) using AMOS. The results showed that the relationship of principal emotional intelligence and teachers’ self-efficacy are moderate, significant and positive (r = .560, p .90), CFI =.987 (>.90) and Ratio Chisq/df = 3.106 (<5.0). From this study it indicates that emotional intelligence has a major influence to teachers’ self-...

Contemporary world food safety standards have emphasized the implementation of efficient food traceability systems, including the correct labeling of products for the authentication of the commercialized species. In this context, Chile has reached an important development in agricultural exportations, reaching near US$ 3.82 billion in 2007. Since the identification based on morphologic and organoleptic characteristics is complex during the elaboration process of aquaculture products, molecular tools need to be developed in order to genetically trace aquaculture products. This study analyzed five species of Chilean commercial mollusks using molecular DNA markers. From the partial sequences of the ribosomal region ITS1-5.8SrDNA-ITS2, the specific primers for the internal transcribed spacers 1 and 2 (ITS1, ITS2) were designed. These primers in 8 fresh species of mollusks, 5 commercial presentations and 3 processed species, obtaining specie-specific band patterns in all cases for both ITS. Additionally, the primers are shown to be highly specific and of replicable amplification products, independently from the commercial presentation of the studied species. Genetically trace aquaculture products. The presence of fraud for species substitution between canned abalone (Haliotis) and loco (Concholepas) species is discussed.

Gastropod mollusks are part of the principal marine resources cultivated and commercialized in Chile. There are native Chilean species such as loco (Concholepas concholepas), locate (Thais chocolata), trumulco snail (Chorus giganteus), keyhole limpets (Fissurella spp.), tegula snail (Tegula atra) as well as exotic species such as red abalone (Haliotis rufescens) and Japanese abalone (Haliotis discus hannai). Despite their importance as marine resources, molecular genetic studies establishing phylogenetic relationships and estimating population genetic parameters are scarce. The aim of this study is to establish a molecular approach among the main commercial gastropod species in Chile. The mitochondrial genes 16S rRNA and COI, and the nuclear ribosomal region ITS1-5.8SrDNA-ITS2 were amplified by PCR and sequencing. Alignment analysis was used to determine systematic relationships at the specific level for the species studied. The results revealed that 7 species are grouped in 4 genetically distinct families (Haliotidae, Trochidae, Muricidae and Fissurellidae). In comparison with COI sequencing, 16S rRNA and ITS1-5.8SrDNA-ITS2 sequencing were relatively more conserved with a divergence percentage for 16S rDNA and ITS1-5.8SrDNA-ITS2 of 1.2% and 1.8%, respectively, contrasting with the value of 10% obtained for COI in abalone.
