Surfing the crime net : policing, crime prevention and community safety in Australia

There can be no doubt that the Internet offers the possibility of increasing access to a range of sources of available information in a timely manner. This is particularly so as we increasingly seek to engage with information from outside our jurisdictional boundaries. While this hints at the effects of globalisation, it is also meant to be suggestive of the practical realities involved in researching (or simply following) developments occurring within emergent federal structures (for instance the European Union) or longer-standing federations such as the United States and Australia. Of course, a department or agency having a homepage and various links is only the start of the process of making information accessible. As will be indicated below, there remain significant limitations in the electronic material available from many agencies. Fortunately, there are also a number of organisations that enable the researcher to access original data and research publications.

Financial crime in South Africa

During the 1990s economic crime began to spiral in South Africa. This phenomenon coincided with the country's transition to a democratic state. The article outlines a number of steps that South Africa took to align its laws with international standards and to improve the legal tools of law enforcement to address the crime wave. A number of successes, for instance the improvement in tax morality, are pointed out but it is argued that co-ordination and co-operation between law enforcement agencies require more attention.

Brief report : The defense mechanisms of homophobic adolescent males : a descriptive discriminant analysis

The study examined the role of defense mechanisms in homophobic attitudes of older male adolescents aged 17e18 years. A cross-sectional survey collected data from final year high school students (N ¼ 86) attending an all male school in a regional centre in Victoria, Australia. The school was identified by teachers as having a problematic culture of homophobic intolerance. Participants were divided into homophobic and non-homophobic groups based on their scores on the Homophobia Scale Questionnaire. Discriminant analysis was conducted to identify the predictors that would best categorise students into those two groups on the basis of defense styles derived from the Defense Style Questionnaire-40 (DSQ-40). The strongest predictors of homophobia amongst defense styles were idealisation, denial, somatisation and devaluation accounting for 18.31%, 17.64%, 13.10% and 11.35% of the variance, respectively. Results generally supported the larger contribution of more immature defenses to higher levels of homophobia.

Partners in crime : collusive corruption and search

This paper analyzes corruption as a collusive act which requires the participation of two willing partners. An agent intending to engage in a corrupt act must search for a like-minded partner. When many people in the economy are corrupt, such a search is more likely to be fruitful. Thus when an agent engages in a search, he raises the net benefit of searching for other similar agents in the economy, creating an externality. This introduces a non-convexity in the model, which consequently has multiple equilibria. The economy can be in stable equilibrium with a high or low level of corruption.

Starting from the high-corruption equilibrium, a sufficient increase in vigilance triggers a negative cascade, leading the economy to a new equilibrium in which no agent finds it profitable to search for corrupt partners. The no-corruption equilibrium continues to be stable if vigilance is then relaxed. This suggests that the correct way to deal with corruption is to launch a ``big push'' with large amounts of resources. Once the level of corruption declines, these resources can be withdrawn.

Multi-core security defense system (MSDS)

Today's security program developers are not only facing an uphill battle of developing and implementing. But now have to take into consideration, the emergence of next generation of multi-core system, and its effect on security application design. In our previous work, we developed a framework called bodyguard. The objective of this framework was to help security software developers, shift from their use of serialized paradigm, to a multi-core paradigm. Working within this paradigm, we developed a security bodyguard system called Farmer. This abstract framework placed particular applications into categories, like security or multi-media, which were ran on separate core processors within the multi-core system. With further analysis of the bodyguard paradigm, we found that this paradigm was suitable to be used in other computer science areas, such as spam filtering and multi-media. In this paper, we update our research work within the bodyguard paradigm, and showed a marked improvement of 110% speedup performance with an average cost of 1.5 ms.

Multi-core Defense System (MSDS) for protecting computer infrastructure against DDoS attacks

Distributed Denial of Service attacks is one of the most challenging areas to deal with in Security. Not only do security managers have to deal with flood and vulnerability attacks. They also have to consider whether they are from legitimate or malicious attackers. In our previous work we developed a framework called bodyguard, which is to help security software developers from the current serialized paradigm, to a multi-core paradigm. In this paper, we update our research work by moving our bodyguard paradigm, into our new Ubiquitous Multi-Core Framework. From this shift, we show a marked improvement from our previous result of 20% to 110% speedup performance with an average cost of 1.5 ms. We also conducted a second series of experiments, which we trained up Neural Network, and tested it against actual DDoS attack traffic. From these experiments, we were able to achieve an average of 93.36%, of this attack traffic.

Crime-prevention jurisprudence? A response to Andrews and Dowden

Recently Andrews and Dowden (2007) published an article proposing that both offender and victim well-being could be enhanced by utilizing the risk–need–responsivity model to guide the legal and court systems in crime prevention (rather than therapy). Consequently, crime-prevention jurisprudence (defined as a law-and-justice objective reflecting the language of personality and social psychology) was proposed as an alternative to therapeutic jurisprudence (defined as a mental-health objective reflecting the clinical language of forensic mental health). The authors erroneously claim that therapeutic jurisprudence is a mental-health concept whose aim is to provide therapy that improves well-being in offenders rather than to demonstrate concern for victims. In fact, therapeutic jurisprudence is a legal concept that utilizes social-science knowledge to highlight the therapeutic and anti-therapeutic impacts of the law, legal procedures, and legal roles on all individuals, including victims. This article will respond to Andrews and Dowden by challenging three assumptions they make regarding the role of therapeutic jurisprudence. This response concludes that the focus of offender rehabilitation should be on enhancing community protection by balancing offender rights and victim rights. Therapeutic jurisprudence already provides such a framework and, therefore, the promise of crime-prevention jurisprudence fails to add value.

Do governments lead or lag in fighting crime?

We examine the Granger causal relationship between police strength and a variety of different types of crime for South Australia. We find that with the exception of assault and homicide in the long run, the crime rate and police strength are neutral.

Modelling the relationship between defense spending and economic growth for the Fiji Islands

The goal of this paper is to examine the nexus between GDP and military expenditure. We model this relationship within a multivariate framework by including exports in the model. We use the recently developed bounds testing approach to cointegration and find that there is a long run relationship among the variables when GDP is the endogenous variable. Normalizing on GDP and using four different estimators, we find that in the long run both military expenditure and exports have a positive impact on GDP. Finally, using the Granger causality test, we find that there is evidence for military expenditure Granger causing exports and exports Granger causing GDP, implying that military expenditure indirectly Granger causes GDP in the short run. In the long run, we find that both military expenditure and exports Granger cause GDP for Fiji. Our findings are consistent with the Keynesian school of thought, leading us to derive some policy implications.

Heterotrimeric G proteins-mediated resistance to necrotrophic pathogens includes mechanisms independent of salicylic acid-, jasmonic acid/ethylene- and abscisic acid-mediated defense signaling

Heterotrimeric G proteins are involved in the defense response against necrotrophic fungi in Arabidopsis. In order to elucidate the resistance mechanisms involving heterotrimeric G proteins, we analyzed the effects of the Gβ (subunit deficiency in the mutant agb1-2 on pathogenesis-related gene expression, as well as the genetic interaction between agb1-2 and a number of mutants of established defense pathways. Gβ-mediated signaling suppresses the induction of salicylic acid (SA)-, jasmonic acid (JA)-, ethylene (ET)- and abscisic acid (ABA)-dependent genes during the initial phase of the infection with Fusarium oxysporum (up to 48 h after inoculation). However, at a later phase it enhances JA/ET-dependent genes such as PDF1.2 and PR4. Quantification of the Fusarium wilt symptoms revealed that Gβ- and SA-deficient mutants were more susceptible than wild-type plants, whereas JA- and ET-insensitive and ABA-deficient mutants demonstrated various levels of resistance. Analysis of the double mutants showed that the Gβ-mediated resistance to F. oxysporum and Alternaria brassicicola was mostly independent of all of the previously mentioned pathways. However, the progressive decay of agb1-2 mutants was compensated by coi1-21 and jin1-9 mutations, suggesting that at this stage of F. oxysporum infection Gβ acts upstream of COI1 and ATMYC2 in JA signaling.
