The Regulation and Development of Bioremediation

The authors describe how federal statutes regulating hazardous wastes create both incentives and disincentives for exploiting the large potential of bioremediation. Ultimately, they argue for regulation attending more to comparative risks and costs

Russia’s natural resources in the world economy : history, review and reassessment

Russia’s role in the global economic system today, and the Soviet Union’s in the past, is dominated by the export of natural resources, particularly oil and gas. The rents earned from these exports are both a source of strength and weakness, as they link the fortunes of Russia’s domestic economy to the volatility of global resource markets. This paper returns to a major research project conducted through the offices of the Association of American Geographers that resulted in Soviet Natural Resources in the World Economy, published in 1983. The project was first conceived in the aftermath of the resource crisis in the 1970s and concluded in the early 1980s as the Soviet Union sought to increase resource exports to support a failing domestic economy. This paper examines the origins, evolution, and management of this seminal work and presents a re-reading of the book in a contemporary context. We develop some of the key themes of the original project and conclude that it has contemporary relevance, as a reliance upon the resource sector remains a defining characteristic of Russia’s political economy and continues to shape Russia’s role in the global economy. We find that the regional dimension that was so important in the original project remains critical as Russia seeks to extend the resource frontier into new regions in the Arctic and the East and, at the same time, reduce its reliance on European markets – that are both stagnant and hostile – by developing new markets in Asia

How to Teach Information Systems Students to Design Better User Interfaces through Paper Prototyping

Given the ubiquity of interfaces on computing devices, it is essential for future Information Systems (IS) professionals to understand the ramifications of good user interface (UI) design. This article provides instructions on how to efficiently and effectively teach IS students about “fit,” a Human-Computer Interaction (HCI) concept, through a paper prototyping activity. Although easy to explain, the concept of “fit” can be difficult to understand without repeated practice. Practically, designing “fit” into UIs can be cost-prohibitive because working prototypes are often beyond students’ technical skillset. Accordingly, based on principles of active learning, we show how to use paper prototyping to demonstrate “fit” in a hands-on class exercise. We provide detailed step-by-step instructions to plan, setup, and present the exercise to guide students through the process of “fit” in UI design. As a result of this activity, students are better able to employ both theoretical and practical applications of “fit” in UI design and implementation. This exercise is applicable in any course that includes UI design, such as principles of HCI, systems analysis and design, software engineering, and project management

Hospitality IT: What Does the Future Hold?

The impact of information technology (IT) is far-reaching and driving dramatic shifts in business paradigms. Trends suggest greater adoption of IT will continue and develop at accelerating rates. Hence, hotel operators and executives must learn how to embrace IT and capitalize on the many capabilities it has to offer while minimizing the threats. The authors attempt to provide a sense of focus and a roadmap to help hoteliers understand the issues, see the future, and find an appropriate on ramp to the information superhighway

It’s déjà vu all over again : COVID-19, the global energy market, and the Russian economy

The COVID-19 pandemic has already disrupted large swathes of the global economy, threatening the growth models of major oil and gas producer countries like Russia. A collapse in oil prices, triggered by the pandemic, once again exposed Russia’s enduring susceptibility to sharp falls in oil and gas prices. We argue that this decline in oil prices came at a time when tectonic shifts in global energy markets had already threatened to reduce the value of future oil and gas revenues. These structural changes were accelerated by the collapse in demand caused by the pandemic. Because the Russian leadership had done little to address the threat posed by the emergence of a new energy order, the economy remained highly dependent on oil and gas sales as the primary source of growth. While measures undertaken since 2014 to reduce the government’s fiscal dependence on high oil prices will help Russia avoid a worst-case outcome of a fiscal or financial crisis, the dependence of other branches of the economy on the energy sector remains high. This has left Russia set once again to experience a deeper recession than that forecast for other energy exporting economies

The Impact of Procedural Security Countermeasures on Employee Security Behaviour: A Qualitative Study

The growing number of information security breaches in organisations presents a serious risk to the confidentiality of personal and commercially sensitive data. Current research studies indicate that humans are the weakest link in the information security chain and the root cause of numerous security incidents in organisations. Based on literature gaps, this study investigates how procedural security countermeasures tend to affect employee security behaviour. Data for this study was collected in organisations located in the United States and Ireland. Results suggest that procedural security countermeasures are inclined to promote security-cautious behaviour in organisations, while their absence tends to lead to non-compliant behaviour

Effects of rundown in soil hydraulic condition on crop productivity in south-eastern Queensland - a simulation study

Declining soil organic matter levels because of cropping have been shown to reduce crop growth and yield, but the effects of changing infiltration and soil hydraulic properties on crop productivity have not been widely evaluated. Cropping systems in south-eastern Queensland have, in the past, involved intense tillage, trafficking with heavy machinery, and changed organic matter cycling, affecting soil aggregation, permeability, water-holding characteristics, and organic matter. The aim of this paper is to determine how important infiltration and soil hydraulic condition has been to the water balance, crop growth, and yield in the past, and may be in the future if management is not changed. Change in physical and chemical condition of the 5 most commonly cropped soils in south-east Queensland (Sodosols, Vertosols with ≤55% clay, Vertosols with >55% clay, Red Ferrosols and Red Chromosols/Kandosols) was measured over 0–70 years of cropping and estimated up to 200 years. The APSIM model was used to predict effects of changing soil condition in a rain-fed, fertilised, wheat-summer fallow cropping system with intense tillage. Decline in infiltration, restricted internal redistribution of water, and increased evaporation reduced water supply to the crop, causing simulated yield to decline by 29, 38, 25, 17, and 13% for the 5 soils, respectively, after 50 years of cropping. Gross margin declined at a faster rate, falling by 36, 50, 40, 20, and 21%, respectively after 50 years because of increasing fertiliser requirement to compensate for declining soil fertility. Crop productivity on most soils continued to steadily decline as period of cropping increased to 200 years. To arrest or reverse this downward trend, it is likely that substantial changes to current cropping systems will be needed, including reducing tillage and trafficking, and improving organic matter levels

Effect of an agri-environmental measure on nitrate leaching from a beef farming system in Ireland

peer-reviewedAgricultural nitrogen (N) management remains a key environmental challenge. Improving N management is a matter of urgency to reduce the serious ecological consequences of the reactive N. Nitrate (NO3−–N) leaching was measured under suckler beef production systems stocked at two intensities: (1) intensive, 210 kg organic N ha−1 with two cut silage harvests; and (2) rural environmental protection scheme (REPS), 170 kg organic N ha−1 with one cut silage harvest. Three replicate plots of each treatment were instrumented with ceramic cups (8 per plot), randomly placed within each plot at a depth of 1 m to collect soil solution for NO3−–N at 50 kPa suction to collecting vessels one week prior to sampling. Samples were taken on a total of 53 sampling dates over 3 winter drainage periods (2002/03, 2003/04 and 2004/05). Over the course of the experiment the mean annual soil solution NO3−–N concentration exceeded the MAC twice out of 15 means (5 treatments over 3 years). The REPS grazing and silage sub treatments had significantly lower mean annual soil solution total oxidized N (TON) concentrations than the respective intensive treatments in years 2 and 3. Annual total NO3−–N losses over the three years in intensive and REPS systems ranged from 55 to 71 and 15 to 20 kg N ha−1, respectively. Mean N surpluses in intensive and REPS systems were 210 and 95 kg ha−1, respectively with the corresponding mean N inputs of 272 and 124 kg N ha−1. The reduction in N inputs under the REPS system results in lower N leaching losses and contributed to a significant reduction in pressures on water quality

The Evolving Menace of Ransomware: A Comparative Analysis of Pre-pandemic and Mid-pandemic Attacks

Drawing upon direct interviews and secondary sources, this paper presents a qualitative comparative analysis of thirty-nine ransomware attacks, twenty-six of which occurred shortly before the outbreak of the COVID-19 pandemic and thirteen of which took place during the pandemic. The research objective was to gain an understanding of how ransomware attacks changed tactics across this period. Using inductive content analysis, a number of key themes emerged, namely: (1) ransomware attackers have adopted more sinister tactics and now commit multiple crimes to maximise their return, (2) the expanded attack surface caused by employees working from home has greatly aggravated the risk of malicious intrusion, (3) the preferred attack vectors have changed, with phishing and VPN exploits now to the fore, (4) failure to adapt common business processes from off-line to on-line interaction has created vulnerabilities, (5) the ongoing laissez-faire attitude towards cybersecurity and lack of preparedness continues to be a substantial problem, and (6) ransomware attacks now pose potentially severe consequences for individuals, whose personal data has become a central part of the game. Recommendations are proposed to address these issues
