Does traditional security risk assessment have a future in information security?

The current information security standards still advocate the use of risk assessment in the prioritisation of security investments. However, prior research on the use of risk assessment methodologies in organisational security has shown that the use of the traditional monolithic risk assessment process described in the current risk management standard is simply not practical at the organisational level. This paper first examines the problems in performing a systematic risk assessment and then discusses the limitations of a traditional risk assessment. To address these limitations, this paper proposes splitting up the current monolithic risk assessment process. The result is an information security assessment framework that puts greater emphasis on situational awareness and allows for better decision making on the prioritization of security investments.

Traditional media and the new media audience

There are many challenges ahead for producers, consumers and regulators of Australian media. Perhaps the biggest challenge is to understand that, along with new media, we now have a new media audience - an increasingly different social formation, often eluding efforts to contain its actions within profitable corporate pathways.

Landscape changes in Denpasar City

Denpasar City is one of cities in Bali Province which faces the problem of landscape change. Most land use is for rice fields, dry lands, crops, housing, grave yards, fish ponds, forests and other functions. Based on Agriculture Office, in 2010 Denpasar City has 20% rice fields of the city’s total area, compared to 41% rice fields of the city’s area in 1992. This shows that Denpasar landscape has changed from agriculture field to commerce, housing, industry etc. and that changing landscape also happened in several green belt areas. This fact is supported by the Agriculture Office report that Denpasar City lose rice field about 25 hectares every year. In contrast, Denpasar City must provide at least 30% of land for open spaces. Furthermore, Denpasar City should keep city based on traditional philosophy such as Tri Hita Karana concept, Rwa Bhineda concept, etc. This paper examines the causes of landscape changes due to growing of population, tourism facilities, economic, and lack of government policy. There are the negative impacts of landscape changes which are associated with social economics and environmental issues. This study seeks to offer guidance for the legitimate use of landscape planning for sustainability development in Denpasar City. Some recommendations could be applied such as prevention of population growth, tourism development base, strict building regulation and increase tax property, and provide the policy and institutional options in land use planning.

Tertius tactics : 'mediated social capital' as a resource of power for traditional commercial news media

This essay reconceptualizes “social capital” as it relates to scholarship regarding the traditional news media. Much academic attention links the news media to Robert Putnam's view which focuses on social capital as enhancing “civic pride” and collective/community involvement. I suggest Putnam's perspective is often adopted without wider exploration of what the theory may offer the future of the commercial news media in western societies. This essay proposes the term “mediated social capital” may be a more suitable lens through which to consider this theory, taking a cue from Pierre Bourdieu who views social capital as a resource of power that may be utilized to maintain or build a position of advantage.

Factors impeding the offsite production of housing construction in China: an investigation of current practice

The promotion of offsite production is a possible future strategic direction for the construction industry as it provides economic, environmental and social benefits. However, in China, the uptake of offsite production, particularly in the housing sector, is relatively low and few studies have identified and examined the reasons behind this trend. This research gap is addressed and factors that inhibit the wider use of offsite production in China’s housing construction industry are investigated. A questionnaire survey was carried out, examining the views of 110 construction professionals in China including developers, designers, contractors, manufacturers and suppliers. Factor analysis of 21 separate variables was undertaken which extracted six principal factors, namely: ‘constructability implementation’, ‘social climate and attitudes’, ‘architectural performance’, ‘costing’, ‘supply chain’ and ‘preparatory stage’. The findings identify both barriers and challenges to increasing the uptake of offsite production in China. This provides a rare insight about the housing construction industry in China with possible implications for other developing countries that are seeking to identify and overcome barriers to the wider uptake of offsite production.

Targeting viral hepatitis using natural milk protein and traditional medicinal herbs

Hepatitis is a major health related disease spread worldwide with frequent occurrence of epidemics. It is a zoonotic disease which leads to jaundice, anorexia, malaise and death. Although, vaccines have been developed against hepatitis A and hepatitis B, it is a challenge to generate vaccines against other prevalent forms of hepatitis which are equally harmful and spread worldwide. Natural products that are obtained from living organisms and found freely in nature have proven to be effective against several types of hepatitis due to presence of pharmacologically important bioactive compounds. Since they are natural products they do not cause much harm to body and can be easily applied or consumed. Our main focus is on hepatitis E virus (HEV) which is an opportunistic pathogen and leads to acute jaundice. This virus is mainly present in developing countries with poor sanitation facilities and effects individuals having weak immune response, mainly children, old people, organ transplant patients and pregnant women. HEV infection makes the patient more susceptible to infections from other viruses as well as HIV. In this review, we discussed about the natural protein known as lactoferrin which is isolated from milk colostrum and extracts of some medicinal plants that have proven to be effective against various forms of hepatitis. Such form of natural therapies forms the basis of modern medicine and major pharmaceutical discoveries.

Evaluation of housing developments for sustainability using a multi-criteria approach

New housing developments in Australia, particularly on Greenfield sites on the edge of existing urban centres, need to be sustainable in environmental and social terms if long term problems are to be avoided. Sustainability is multi-dimensional and existing analyses have been found to be inadequate in assessing housing developments holistically. This paper describes research which has used five criteria (energy use, resource use, neighbourhood character, neighbourhood connectivity and diversity), representing 31 indicators, to assess three housing precincts of a regional city in southern Australia. The method has been found to produce useful assessments of sustainability. The method has the potential to inform future housing developments and to be used to improve existing suburbs.

Challenging the traditional sequence of teaching introductory calculus

Despite considerable research with students of calculus, rate, and hence derivative, remain difficult concepts to teach and learn. The demonstrated lack of conceptual understanding of introductory calculus limits its usefulness in related areas. Since rate is such a troublesome concept, this study piloted reversing the usual presentation of introductory calculus to begin with area and integration, rather than rate and derivative. Two classes of first-year university students taking introductory calculus were selected to pilot the effect of changing the sequence; one class was a control group and the other class followed the reversed sequence. Advances in technology, especially computer algebra systems (CASs) may facilitate new ways of studying mathematics. In this study, handheld CASs were used to support students’ thinking as they grappled with the concepts of introductory calculus. The use of CASs enabled consideration of symbolic patterns and numerical integration leading to a deeper conceptual understanding of integration. The easy access to the multiple representations of functions provided by CASs facilitated an exploration of rate where each representation highlighted different aspects of rate resulting in deeper conceptual understanding of differentiation.
