Challenges for rural and remote road safety

The growing national and international awareness of the increased representation of serious injuries and fatalities in rural and remote areas is the focus of this paper. Australia was one of the earliest countries to try to address this issue with a targeted national action plan in 1996. This was an important document but the most recent national plan fails to dedicate attention to developing countermeasures for the particular problems of improving road safety in these regions. The findings of a major program of research in Northern Queensland are discussed to stimulate interest and research into potential countermeasures. Specifically, the need to monitor clusters of crashes as a focus for intervention and local ownership is advocated. Taking action towards a national reduction of speed limits on rural roads and investment in proactive research based trials of drink driving countermeasures such as courtesy buses is strongly advocated.

Cloning and analysis of 16 Rab genes from macronuclear DNA of Euplotes octocarinatus

Rab proteins belong to the largest family of the Ras superfamily of small GTPase that play an important role in intracellular vesicular traffic. So far, almost 60 members of Rab family have been identified in mammalian cells. To further study the diversity and function of Rab protein in evolution, unicellular protozoa ciliates, Euplotes octocarinatus, were used in this study, Rab genes were screened by PCR method from macronuclear DNA of E. octocarinatus. Sixteen Rab genes were obtained. They share 87.6 - 99.5% identities. Highly conserved GTP-binding domains were found. There are some hot regions that diverse sharply in these genes as well.

Unconscious relational encoding depends on hippocampus

Textbooks divide between human memory systems based on consciousness. Hippocampus is thought to support only conscious encoding, while neocortex supports both conscious and unconscious encoding. We tested whether processing modes, not consciousness, divide between memory systems in three neuroimaging experiments with 11 amnesic patients (mean age = 45.55 years, standard deviation = 8.74, range = 23-60) and 11 matched healthy control subjects. Examined processing modes were single item versus relational encoding with only relational encoding hypothesized to depend on hippocampus. Participants encoded and later retrieved either single words or new relations between words. Consciousness of encoding was excluded by subliminal (invisible) word presentation. Amnesic patients and controls performed equally well on the single item task activating prefrontal cortex. But only the controls succeeded on the relational task activating the hippocampus, while amnesic patients failed as a group. Hence, unconscious relational encoding, but not unconscious single item encoding, depended on hippocampus. Yet, three patients performed normally on unconscious relational encoding in spite of amnesia capitalizing on spared hippocampal tissue and connections to language cortex. This pattern of results suggests that processing modes divide between memory systems, while consciousness divides between levels of function within a memory system.

Changing cultural clusters: A research note. ACES Working Papers, August 2009

The purpose of this research note is to investigate the changing cultural clusters that emerged between the studies of Hofstede (1970s) and GLOBE (1990s) using similar measures and overlapping countries. Our study analyzes the world's cultural clusters using two seminal and comparable cultural classifications: Hofstede and GLOBE. Four common cultural dimensions are empirically examined: individualism, power distance, uncertainty avoidance, and masculinity. We use two leading methods from cluster analysis and display data in both dandrograms and pie chart forms showing the grouping of countries. Our results suggest diverging cultural typologies that transcend geography, language, and religion. Countries are engaged in selective cultural borrowing that leads to new and changing global cultural structures.
