The interpretation of exploration oriented geochemical data frequently requires the recognition of subtle features related to mineralization, from the more obvious geochemical expressions of bedrock and surface environments. A number of previous investigations have indicated the potential of various computerized interpretational procedures as aids in identifying these features in geochemical data. The present investigation was concerned with the interpretation of multi-element data from a 750 mile2 {1942.5 km2) area of the Notre Dame Bay district of Newfoundland. The area is underlain by a series of Ordovician and Silurian sediments and volcanics and intrusives overlain by glacial deposits mostly composed of glacial till. Massive sulfide mineralization including the Whalesback and Gullbridge deposits occur within the Ordovician volcanics. R mode factor analysis was employed to establish the character and distribution of the principle metal associations related to bedrock and surface environment contributing to the overall data distribution. The factor scores were regressed against the individual metal concentrations of the elements composing the respective factors, the resulting residuals of the metals reflecting the component of metal related to some sources other than those reflected by the metal associations established by factor analysis. Anomalous areas of residual copper and zinc distributions indicate the areas of known sulfide mineralization more closely than the untreated metal distributions. On this basis, anomalous areas of residual copper and zinc, unrelated to known sulfide mineralization warrant further exploration investigation. It is therefore concluded that a combination of factor and regression analysis on multi-element data from the Notre Dame Bay district of Newfoundland serves to highlight subtle though significant features in multi-element data possibly related to mineralization that were not apparent from a consideration of the untreated data.

The study focuses on the significance of agricultural credit that can bring change in the life of farmers and rural people. The rural sector is mostly neglected and lacks adequate finance that’s needed to back the sector. However, there are certain financial institutions that work for the welfare of the sector and lend credit facilities to farmers and associated people, for their wellbeing. The current study majorly recognizes the impact and benefits of these credit facilities in improving the situation of farmers at several unnoticed places, including Cachar district. The present study is exploratory in nature. It has explored the role of credit in farmer’s life. The data was collected through a structured questionnaire from 283farmers of Cachar district. The statistical tools applied for the study were “Exploratory Factor Analysis (EFA)”, and “Multiple regression analysis.” The factors identified were Economic Development, Agro Development and Family and Social Development. It was found that there is a significant role of credit in the development of all the three factors.

The Relationship

Purpose – The purpose of this paper is to explore the contours of fairness by showing how different facets of fairness impact three important employee outcomes (job satisfaction, turnover intention and employer advocacy) and examining the mediating role of quality of management and leadership (through perceptions of both senior management and the quality of exchange with immediate supervisors) in attenuating negative impacts of unfairness on these outcomes. The study extends the concept of fairness beyond the traditional focus on organizational justice and models the mediating role of leadership on the relationship between (un)fairness and the three employee-level outcomes in a sample of employees representative of the UK workforce. Design/methodology/approach – Data were obtained from a nationally representative sample of 2,067 employees in the UK. Exploratory factor analysis and then confirmatory factor analysis is used to refine three unfairness factors and address their dimensionality of the unfairness scale and then multiple regression analysis is used to test a fairness-leadership-employee performance outcome model. Findings – Results of multiple regression analysis revealed that both trust in leadership and leader-member exchange partially mediate the relationship between organizational (un)fairness and job satisfaction, advocacy and turnover intention, respectively. Practical implications – The findings highlight the important role that leaders play in influencing the relationship between perception of unfairness and employee outcomes. This has implications for both theory and practice as it suggests that the pattern of inclusion that leaders create through the relationships that they develop with their followers has a significant impact on the relationship between unfairness and the work outcomes. They not only must manage traditional perceptions of justice, but also the assessments employees make about trust in management judgements and the perceived consequences of such judgements. Originality/value – In an environment where perceptions of unfairness are becoming both more endemic but also more complex, the study shows that both senior leaders and immediate supervisors have important agency in managing negative consequences. Through the measurement of satisfaction, turnover intention and employer advocacy it also provides potential links to link fairness into the engagement literature.

The fundamental role of emotions in education has been revealed in recent years. The control-value theory of achievement emotions has been postulated as one of the most used theories in this field. Thanks to the Achievement Emotions Questionnaire (AEQ), achievement emotions have been measured in different subjects and countries. The purpose of this research was to adapt and validate this questionnaire to assess achievement emotions in physical education. The sample of participants consisted of 902 (Mage = 13.15, SD = 1.17) secondary education students from various secondary schools in Spain. The psychometric properties of the Achievement Emotions Questionnaire for Physical Education (AEQ-PE) indicate that the scales are reliable and valid, as demonstrated by exploratory and confirmatory factor analysis, temporal stability, internal consistency and regression analysis. Considering the results achieved in the present study, the AEQ-PE opens a range of possibilities for both teachers and researchers. This instrument will help to understand the role of emotions in student learning and their motivation towards physical education.

The purpose of this study is to investigate whether hedonic motives and browsing affect impulse buying and examine the role of browsing as a mediator between hedonic motives and impulse buying.In this context, a model was proposed and tested on a sample of customers who made an impulse purchase in Ankara. Confirmatory factor analysis supported the components of hedonic shopping motives such as adventure shopping, gratification shopping, role shopping, value shopping, social shopping, and idea shopping. Moreover, the results of the regression analysis showed that hedonic motives and its dimensions such as adventure, gratification, and idea have a positive impact on impulse buying. Consumers’ browsing behaviorinfluenced impulse buying positively. The mediating role of browsing between hedonic motives and impulse buyingwas also identified.

This article examines the problem of self-relationship of students-psychologists in the process of professionalization, on the basis of correlation and factor analysis is compared two groups of subjects of junior and senior courses with varying degrees of involvement in the professional activities of a psychologist, analyzes the causes and possible results of changes in self-relationship. The article established the following patterns: motivational and semantic mechanisms of self-development assume the impact on the personality of the future specialist through a change in the meaning of activity. Depending on the level of self-fulfillment of the individual, the appropriate dynamic semantic systems were allocated at different stages of the training. External negative motivation, as professionalization begins to correlate more strongly with both self-esteem and global self-relationship. This is a consequence of the abandonment of externally asked forms of activity in favor of the growth of self-determinized motivational tendencies. The role of external evaluation does not decrease, but the tolerance for being in a highly competitive environment increases. Negative external assessments activate the desire to confirm the level of global self-relationship. Factor analysis allowed us to identify an integral complex of "primary professionalization" that combines high resistance to external negative effects on self-esteem, high conceit, as well as professionally important for the psychologist traits of sensitivity and propensity to carefully analyze behavior. The impact on the formation of a professional psychologist during the course of training can be distinguished by how objectively they are, or perceived subjectively significant for students as controlling, informing or amotivating, how much weight their contribution to the formation of internal motivation of the individual. In particular, the study found that changes in self-relationship at different stages of professionalization lead to the development of sensitivity as a factor of empathy, a number of qualities become self-determinized depending on the degree of importance for the future profession.

This study is aimed at verifying the conception that a strong corporate culture supported with a positive ethical environment is central for directing and guiding the behavior of individuals toward achieving organizational objectives. The rationale for this study stems from the circumstance that formal controls systems suffer from consecutive failures, as the performance of organizations is still suffering from financial collapses. Reasons behind such failures might be related to the insufficient appreciation of the culture-based controls given that formal controls are influenced by the human nature of employees and the affixed moral side.Data subject to analysis are obtained from a judgmental sampling method using a self-completion questionnaire covering the listed companies at Jordan Securities Commission. A factor analysis and a standard multiple regression analysis have been conducted with the aim of proving the hypotheses of the research. The research results show that strong corporate culture supported with a positive ethical environment can direct the behavior of employees for the good of organizations. Results also support the importance of involvement of top management considering its role in filling the gap between the embraced and the workable values and beliefs of an entity.

Abstract Current portable X-ray fluorescence (pXRF) technology can rapidly and inexpensively yield concentrations of geologically significant elements, typically with instrument detection limits below several tens of parts per million. Based on conventional XRF whole-rock geochemical data, both the Ishikawa alteration index and the chlorite-carbonate-pyrite index increase with proximity to sulfide mineralization at Myra Falls. However, available pXRF technology is typically unable to detect all the elements required to calculate these alteration indices. As a result, there is a need to utilize the elements that are readily detectable using pXRF and apply these to hydrothermal alteration assessment. We propose that Rb/Sr ratios provide a robust proxy for the Ishikawa alteration index and demonstrate that conventional whole-rock XRF analytical results for Rb and Sr can be reproduced using pXRF analysis from drill core surfaces. At Myra Falls, the Rb/Sr ratios vary from <0.1 for least altered rocks, 0.1 to 0.5 for weakly altered rocks, 0.5 to 1.0 for moderately altered rocks, 1.0 to 2.0 for strongly altered rocks, and >2.0 for intensely altered rocks. Downhole profiles of alteration intensity generated from systematic pXRF analysis of drill core surfaces can be used to inform drilling and targeting decisions. The application of the Rb/Sr ratio as a proxy for alteration intensity extends beyond this case study and can be applied to other hydrothermal systems that produce phyllosilicate minerals as alteration products of feldspar.

The rise of exclusive puritanism movements challenges several communities to live in peaceful coexistence. This research aimed to observe the level of interreligious contact on university students. This was a threefold study. The first part was an initial inquiry to construct an interreligious contact scale. The second sought to see the inferential association between interreligious contact, belief in religious teachings (i.e. fundamental religious belief, kindly religious belief, and meta-religion endorsement), and collective narcissism. The third part was to investigate the differences between those variables, between students who joined student political organizations with religion-based ideology and those who did not. There were 381 respondents from various religious backgrounds (e.g. Muslim, Christian, and other) participating in this research. The result of the exploratory factor analysis indicated a unidimensionality of the interreligious contact scale. Regression analysis found that fundamental religious belief and collective narcissism made individuals less likely to exhibit interreligious contact. However, kindly religious belief and meta-religion endorsement encouraged interreligious contact. In addition, the independent sample t-test suggested that there was a difference of inclusivism level between religion-based student organization members and non-members. Members of such organization tended to exhibit a lower level of interreligious contact, while their level of fundamental religious belief and collective narcissism were higher compared to their non-member counterparts.

Academic achievement in immigrant children and adolescents is an indicator of current and future adaptive success. Since the future of immigrant youths is inextricably linked to that of the receiving society, the success of their trajectory through school becomes a high stakes issue both for the individual and society. The present article focuses on school success in immigrant children and adolescents, and the role of school engagement in accounting for individual and group differences in academic achievement from the perspective of a multilevel integrative model of immigrant youths’ adaptation ( Motti-Stefanidi, Berry, Chryssochoou, Sam, & Phinney, 2012 ). Drawing on this conceptual framework, school success is examined in developmental and acculturative context, taking into account multiple levels of analysis. Findings suggest that for both immigrant and nonimmigrant youths the relationship between school engagement and school success is bidirectional, each influencing over time the other. Evidence regarding potential moderating and mediating roles of school engagement for the academic success of immigrant youths also is evaluated.
