    Securing library information system: Vulnerabilities and threats

    Get PDF
    Threats and vulnerabilities in computers and networks are common nowadays since computers are widely used by the public. The risks of computer threats and vulnerabilities are high since most computers are connected to the internet. Library Information Systems is also vulnerable to attack since it is a public access institution. Majority of users are naive when it comes to computer and network securities. Some breaches in Library Information System are intentional and some are unintentional. Risks analysis should be done to find the threats and risks in designing the Library Information System. Threats are made possible due to lack of proper procedures, software flaws and policies. The administrators should anticipate all the possible attacks and their mitigation techniques. In this paper, we will try to address various issues arise from this vulnerabilities and threats. We will also describe how we can reduce and overcome this vulnerabilities and threats

    An Empirical Investigation of Gaming Responses to Performance Incentives

    Get PDF
    This paper studies a particular kind of gaming responses to explicit incentives in a large government organization. The gaming responses we consider occur when agents strategically report their performance outcomes to maximize their awards. An important contribution of this work is to examine whether this behavior diverts resources (e.g. agents' time) from productive activities or whether it simply reflects an accounting phenomenon. We evaluate the efficiency impact of the behavior we identify and find that it has a negative impact on the true goal of the organization.

    Carbon Footprint Assessment and Mitigation Options of Dairy under Chinese Conditions

    With the rapid human population growth and economic development, demand for animal products continues to increase and livestock production rapidly expands. Greenhouse gases (GHG) emission from livestock research 7.52 billion tons CO2-eq per year, accounting for 50% of agricultural emissions and 18% of global anthropogenic GHG emissions (FAO, 2014), making it become an important source of GHG emissions. The Chinese livestock production emits 373 GHG of million tons CO2-eq. Methane (CH4) emitted from enteric fermentation is 10.74 million tons (equivalent to 225.6 million tons CO2-eq), accounting for 60.7% of total livestock GHG emissions. CH4 emitted from manure management is 3.33 million tons (equivalent to 69.9 million tons CO2-eq), accounting for 18.9% of total livestock GHG emissions. Nitrous oxide (N2O) emitted from manure management is 0.25 million tons (equivalent to 77.2 million tons CO2-eq), accounted for 20.4% of the total livestock GHG emissions (MEE, 2018). The enteric fermentation and manure management contribute 40% to agricultural GHG emissions. Expansion of livestock production results in high demand of feedstuffs, bringing greater pressure on natural resources. It is of particular concern that the livestock sector has already been a major user of natural resources. For example, approximately 35% of total cropland and 20% of green water have been used for animal feed production (Opio et al., 2013). Feed-related emissions represent about half of total emissions from livestock supply chains (Gerber et al., 2013). Therefore, it is very important to evaluate GHG emissions from the whole life cycle of livestock production. Besides improved manure utilization and water usage efficiency, management of carbon emissions and carbon footprint is highlighted as an important research topic. This project is expected to identify and execute appropriate interventions for reducing carbon footprint and economic cost of dairy production

    LOGISTICAL COSTS AND RISKS OF MARKETING GENETICALLY MODIFIED WHEAT

    Genetically modified (GM) grains have increased in importance. Moving biotech grains from producers to processors is a challenge for the grain handling system that could involve increased segregations. The objective of this research is to determine how testing strategies affect the logistical costs of a grain pipeline when GM wheat is present. A logistical model was developed and simulated to analyze impacts of uncertainty in demand, receipts, test accuracy, rail deliveries, and transit time. Sensitivities were conducted on certain variables to determine their effects on logistical costs. Analysis revealed that logistical costs are impacted by the number of quality categories and uncertainties in the system. Adding GM grains increased costs due to testing requirements and increased segregation demands as the number of wheat categories rises.Genetically Modified (GM) Grains, Logistical Costs, Testing, Risk, Segregation, Crop Production/Industries, Research and Development/Tech Change/Emerging Technologies,

    Over half of the farmers in the Railbelt area of Alaska located on their farms after World War II, Farming on the current scale is so new that it is in a constant state of flux. Changes frequently occur in farm practices and in farm ownership. Shortage of cropland and inadequate buildings place a temporary ceiling on expansion of major lines of farming in all agricultural areas. Liberal amounts of credit must become available for continuation of the rapid expansion experienced in the past. The major reason why various kinds of agricultural enterprises developed as they have in leading agricultural areas can be found in the history of agricultural settlement. The Matanuska Valley provided nearly half of the agricultural production in Alaska in 1952, More families were engaged in farming in this valley than in any other area in Alaska. Milk sales topped all others as a source of income and more full-time farmers had dairies than any other enterprise. Potatoes were second in importance with numerous part-time farmers growing varying acreages. Poultry and vegetable production both follow a similar pattern of numerous small producers and only a few specialized farms. The Tanana Valley was the second most important agricultural area in 1952, Most farmers relied on potatoes for their major source of farm income. Vegetables were grown as a minor enterprise on several farms. Few flocks of hens were found., Although interest in dairy farming has been strong in this area, only 3 farms produced milk in surplus quantities in 1952* Of these 3 farms, one was a public institution, one was exceptionally large,, and one was exceptionally s^iall. Lack of housing and domestic water have deterred both dairy and poultry farming,, Compared to the above areas, agricultural development on the Kenai Peninsula has been slow. Farmers have been greatly handicapped by lack of a source of borrowed capital and by distance from a si2able market. Livestock and poultry are the major enterprises. Even though 12 of the 19 farmers interviewed grew potatoes, acreages usually were small. Vegetable production is not great because most of the produce is sold locally and not much produce is demanded by this market. Shortages of equipment necessitate a great deal of hand work.In cooperation with the UNITED STATES DEPARTMENT OF AGRICULTUR
