Wireless Local Area Network Security : An Investigation Into Security Tool Usage In Wireless Networks

Many organisations and individuals installing wireless local area networks (WLANs), which are based on the IEEE 802.11 b standard, have little understanding of the security issues that surround this technology. This study was initiated to determine how WLAN security issues affect organisations in Perth, Western Australia. The scope of the study was restricted to 802.llb WLANs operating in infrastructure mode, where all traffic is transmitted by wireless access points (APs). This study was conducted in two phases. The general aims of the first phase were to determine the number of detectable WLANs in the Perth Central Business District (CBD) and subsequently, the percentage of them that have enabled Wired Equivalent Privacy (WEP). Additionally, phase 1 was able to show how many WLANs were still using the manufacturer\u27s default settings and how the network devices may be grouped according to manufacturer. The general aims of the second phase were to find out if the IT managers of various Perth organisations were aware of the security issues related to WLANs and to find out the degree to which the security tools and processes have been implemented. These aims were also achieved and in addition, anecdotal information was collected and analysed. The results of this study indicate that in the Perth CBD, the majority of those persons responsible for the implementation and management of wireless networks are aware of the problems and have taken steps to secure their networks

Diversity in information and communication technologies: The cost of lost opportunities

The Information and Communication Technology (ICT) industry develops products that are used by many people regardless of gender, age, social status, ethnicity, or religion. Technology has had a significant impact on the way that information is produced, stored and communicated, especially in the fields that have traditionally been heavy producers of information such as libraries and education institutions. Though all types of people use technology, not all types of people are involved in the design and development of technology. Women represent just twenty percent of Australian ICT professionals. They often receive less pay than their male colleagues and are greatly under-represented in management and executive level positions. The rate of participation of women in ICT has declined steadily since it peaked in the mid eighties, while at the same time, the participation of women in other previously male-dominated fields such as mathematics and physics has continued to climb. Minority and ethnic groups such as Native Americans, African Americans, Hispanics, and Australian Aboriginals are also underrepresented in ICT, both in tertiary studies and in industry. This under-representation of women and minorities in ICT results in a lack of diversity in the creative teams who design and develop this technology. Apart from the issue of equity or fairness, a lack of diversity means that technology is being produced from a very narrow viewpoint which may affect its quality. There is also a hidden or ‘opportunity cost’ in technology that is never designed and is not produced because of a lack of diversity in creative teams. This concept paper will address the potential impacts that a lack of diversity in the teams creating technology might have on the way that libraries operate, and the way that information is produced, stored and communicated

Constitutional Law - Freedom of Speech - Public Forum - Captive Audience - Transit Advertising on Municipally Owned Transit System

The United States Supreme Court has held that a municipality does not violate a candidate\u27s right of free speech and equal protection under the first and fourteenth amendments to the United States Constitution when it sells space on its transit vehicles for commercial and service advertisements but refuses to accept political advertising of a candidate for public office.

Citrus World, Inc. 1980 - 2015 : an examination of adaptation in a long-enduring U.S. agricultural marketing cooperative

Abstract from public.pdf.A common characteristic of enduring entities is their adaptive capability. Yet the nature and process of adaptation in a cooperatively owned enterprise where capital structure constraints, membership restrictions, diffuse objectives, plurality of interests and democratic processes are present, is not well understood. Adapting an Analytic Narrative approach, this thesis presents a detailed narrative of the practice of adaptation to endogenous and exogenous forces by the leaders of Citrus World, Inc. ("CWI") between 1980 and 2015. Formed in 1933, CWI is a federated, single commodity agricultural marketing cooperative based in Lake Wales, Florida USA. Applying eight selected organizational theories as a lens through which to view the CWI's evolution over that period, I consider the explanatory power of each theory and its potential for informing the future development of frameworks for the study of cooperative organizations. The theories were selected for their dynamic nature and relevance to collective organization, governance, leadership and adaptation. Six of the theories relate directly to factors which promote or impede enduring collective enterprise, one to business adaptation and one to organizational leadership. The purpose of this exercise is to stimulate advancement toward a more comprehensive framework for study of agricultural cooperatives that may, in turn, serve to inform the practice of adaptation by cooperative agents and principles alike

Wheat Cleaning and its Effect on U.S. Wheat Exports

This analysis shows that there could be net gains to the U.S. wheat industry if all U.S. export wheat were to be cleaned to a dockage level between 0.35 to 0.40 percent. These results are based on survey results of major importers of U.S. wheat, and a model of world wheat trade. Larger benefits to the U.S. wheat industry would be possible from cleaning only wheat destined to countries that demand higher quality U.S. wheat. However, these gains in export revenue from selling cleaner wheat could be offset if other exporters, especially Canada, responded in ways that would maintain their market share.wheat, grain quality, trade model, Crop Production/Industries, International Relations/Trade,

Quality of life impairment after a diagnosis of Cushing's syndrome

This brief review is devoted mainly to publications in the last 5 years dealing with health-related quality of life (QoL) after a diagnosis of endogenous hypercortisolism, due to pituitary-dependent Cushing's disease (CD) or any other cause of Cushing syndrome (CS). Despite improvement after treatment, persistent physical morbidity, neurocognitive problems like worse executive capacity and memory as well as stress intolerance, depressive symptoms and more anxiety, lead to long-term impairment of QoL

British expatriates and the anti-Brexit backlash

A large number of British citizens live elsewhere in Europe and many have the right to vote in UK elections. Yet little is known about their political preferences given there are no designated overseas constituencies for expatriate representation. Drawing on new survey evidence, Paul Webb and Susan Collard write that while expatriate voters have traditionally been assumed to vote more often for the Conservative Party, this no longer seems to apply for those living in EU countries following Brexit
