Organic chemical signatures of New Zealand carbonate concretions and calcite fracture fills as potential fluid migration indicators

Macroscopic calcite crystals are common in sedimenta¬ry strata, occurring both as tectonic veins and also filling one or more generations of septarian rupture or later brittle fractures in calcareous concretions. Traces of hydrocarbons are frequently present in calcite crystals, especially near active petroleum systems, and are routinely the object of fluid inclusion studies linking source and migration pathway. Such calcites are shown here also to contain fatty acids in widely varying amounts ranging from 0.2 to more than 5 μg/g. Vein calcites examined are typically near the lower figure, close to analytical blank levels, and this is also true of some concretionary fracture fill calcites, notably those from the Palaeocene Moeraki ‘boulders’. Other concretionary fracture fill calcites (Jurassic, Scotland; Eocene, Waikato Coal Measures and associated marine strata) have much higher fatty acid contents, especially those filling later brittle style fractures. Although usually less abundant than the fatty acids in the concretions themselves, they lack the long chain n-acids derived from terrestrial vegetation and are commonly dominated by dioic acids. Exceptionally, in the calcitic septarian fill of a sideritic Coal Measures concretion, their abundance far exceeds that of concretion body fatty acids. They appear to be fluid transported, probably in aqueous solution, and have molecular signatures potentially distinctive of maturing organic matter sources from which the fluids derived

Using 'Inclusive Wealth' to Measure and Model Sustainable Development in Australia: A working example

Australia in 1992 adopted the National Strategy for Ecologically Sustainable Development to ensure all future development occurs in a 'sustainable' manner. Measurement of the nation's sustainable development is currently conducted through the OECD Environmental Performance Review and various other ad-hoc indicators or measures have been proposed, such as greening the national accounts (Green Gross National Product) and the Genuine Progress Indicator. No one has identified a clear and precise way to either measure or model sustainable development in Australia. By trialing the implementation of inclusive wealth theory in Australia, this paper aims to identify and comment on the issues of measuring and modelling sustainable development as a stock measure in Australia (measuring the change in composition of national assets over time). Conceptual issues of implementation will be discussed with examples provided from two trial regions Goulburn Broken Catchment (VIC) and Murrumbidgee Valley (NSW).inclusive wealth, sustainable development, capital stocks, production systems, Production Economics,

Adoption of internet banking theory of the diffusion of innovation

The innovation diffusion theory (IDT) could be considered as one of the earliest theories that attempts to explore factors that influence an individual to adopt an innovation or a new technology. The theory suggests five key beliefs that influence the adoption of any innovation: relative advantage, complexity, compatibility, trialability, and observability. The purpose of this study was to test part of IDT’s attributes empirically. We used Internet banking as the innovation or the targeted technology. We surveyed 1164 business and MBA students in four public universities in Malaysia. Structural equation modelling was used to analyse the data. The results showed that relative advantage, compatibility, and trialability have a significant effect on att itude. Consequently, attitude significantly aff ects the intention to use Internet banking. Based on the findings, implications to practice are offere

Innovating with Technology: The Impact of Overload, Autonomy, and Work and Family Conflict

Innovation with information technology (IT) helps companies gain more from their IT investment. IT innovation by individuals can be affected by many factors (such as overload, autonomy, and work / family conflict) and developing a better understanding of these factors can help managers make better decisions about the work environment. Using Partial Least Squares (PLS) to analyze data collected via an online survey from the Pan-Pacific region (n = 233), we found that education, number of extended family members responsible for, and autonomy (work method and work criteria) had a significant effect on trying to innovate with IT. Interestingly, we found that neither work-family conflict nor family-work conflict had a significant direct effect on trying to innovate with IT. Our study found only partial support for previous studies that suggested gender was a significant moderator between perceived overload, autonomy and trying to innovate with information technology. The results of this study are important to both practitioners and researchers as they raise important questions about potential impediments to individual innovation with technology

Social Influence and Willingness to Pay for Massively Multiplayer Online Games: An Empirical Examination of Social Identity Theory

The development and sale of massively multiplayer online games has emerged as a significant part of the 21st century entertainment industry. Yet, firms competing in this sector of the videogame industry vary in their ability to generate revenue from their products. We contend that social influence constitutes one primary factor that determines which massively multiplayer online game individuals consume. Using social identity theory for our theoretical underpinning, we argue that the identity that membership in important social groups provides influences individuals. We investigate the effects that two identity-related constructs, consumer-brand identification and social identity complexity, have on satisfaction and willingness to pay a subscription fee for a massively multiplayer online game. Our results suggest that social influence has a complex relationship with an individual’s willingness to pay. Consumer-brand identification and social identity complexity had significant direct relationships with willingness to pay, while consumer-brand identification had a significant indirect relationship with willingness to pay through satisfaction. Additionally, social identity complexity significantly moderated the relationship between consumer-brand identification and willingness to pay. Overall, our results support social identity theory’s ability to explain how social influence occurs for individuals that play massively multiplayer online games

AN EMPIRICAL INVESTIGATION INTO DECISION SUPPORT ENVIRONMENTS: FINDINGS AND CONSIDERATIONS

The environment in which a DSS is developed can have a significant impact on the development and satisfaction provided by the DSS. A questionnaire was sent to nonacademic TIMS members in an attemmpt to identify specific DSS environments, the capabilities provided by these DSS, and environmental factors that significantly influenced the DSS environment. This paper presents the results of this investigation

Social Influence and Willingness to Pay for Online Video Games

Social influence is an important factor in guiding individual behavior, including purchase decisions. The online gaming industry has demonstrated itself to be one of the most successful business sectors to integrate the Internet into its business models. The purpose of the study is to investigate the influence an individual’s social environment has on willingness-to-pay a subscription fee for an online video game. Specifically, social influence is conceptualized as occurring on three levels within an individual’s social environment: the micro-, meso-, and macro-levels. Using a survey research methodology, this study examines the effects that these influences have on expected benefit, willingness-to-pay, and each other

The Interrelationship Between Objectives and Practices in Information Security Management

To help practitioners effectively implement security programs, we explored the interrelationship between security objectives and practices by conducting a canonical analysis based on the data from 354 certified security professionals. We found that for moderately information-sensitive organizations, “Confidentiality” had the highest correlation with information security practices. In these organizations, the security practice contributing most to the security objectives was “Access Control”. For highly information-sensitive organizations, the “Confidentiality”, “Accountability,” and “Integrity” together determine the security practices. In these organizations, the major security practices that impact on security objectives are: “Access Control”, “Organizational Security”, and “Security Policy”. “Access Control” was the only practice contributing to information security objectives in both groups. The items in this dimension focused mainly on technical controls

E-Commerce Adoption:Perceptions of Managers/Owners of Small and Medium Sized Firms in Chile

Although the adoption of e-commerce is widely studied in the industrialized world, only a small number of these studies focus on developing countries. An even smaller fraction of these studies focus on small and medium sized enterprises (SMEs), which account for a high percent of the economy generated in developing countries. In this study, managers/owners of SMEs in Chile identified variables that differentiate between adopters and non-adopters of e-commerce. The analysis suggests that Chilean managers/owners most receptive to adopting e-commerce possess the financial and technological resources to implement it, see e-commerce as increasing managerial productivity and supporting strategic decisions, feel external pressure to put e-commerce into operation, perceive e-commerce as compatible with preferred work practices and existing technology infrastructure, and perceive e-commerce as useful for their firms
