Tallgrass Prairie Remnants of Western Iowa Cemeteries.
Tallgrass prairie remnants situated in eight western Iowa cemeteries were sampled during 1995 and 1996 to compare both the frequency and season of mowing and burning on plant species composition. Dominant, native tallgrass prairie species, such as big bluestem (Andropha gerardii), Indian grass (Sorghastrum nutans) and leadplant (Amorpha canescens), generally showed a significant increase with burning, whether mowed or not. Mowing, however, adversely affected other species, including flower spurge (Euphorbia corollate) and porcupine grass (Stipa spartea), whether burned or not. Non-native species, in particular smooth brome (Bromus inermis) increased with mowing and the absence of fire. Overall, my study suggests the importance of selecting the appropriate type of frequency of management in order to maintain the native tallgrass prairie plant diversity. Further, it supports the appropriate use of fire rather than mowing, both to favor native species and to limit the advance of non-native species
What Works for Aboriginal and Torres Strait Islander Men? A Systematic Review of the Literature
Aboriginal and Torres Strait Islander men experience significantly higher rates of suicide, trauma, alcohol related deaths and unemployment than other Australian men. Despite significant levels of government intervention, rates of family violence, unemployment and incarceration continue to increase in Aboriginal and Torres Strait Islander communities. As a subset of the Aboriginal and Torres Strait Islander population, there has been a lesser focus on how to meaningfully improve the wellbeing of Aboriginal and Torres Strait Islander men. This systematic review seeks to understand what interventions, programs and activities are successful in improving the wellbeing of Aboriginal and Torres Strait Islander men and thereby the wellbeing of their communities. A thorough search of the literature was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Fifteen studies met the inclusion criteria. Analysis of the programs, activities and interventions evaluated in these studies indicated two prominent themes that were successful in improving the wellbeing of Aboriginal and Torres Strait Islander men: strengthening identity and increasing social connection. The mechanisms contributing to these outcomes are discussed, as are implications for policy and future research
Which Way From Here? An Exploration of Local Perspectives on Strengths, Needs and Goals in the Aurukun Community
Aurukun is a small Aboriginal community located in remote Cape York, Far North Queensland. This study explores local perspectives on the goals, strengths and areas of need in the community, and perceptions of the role of a man in Aurukun. Seventeen individuals from the Aurukun community were informally interviewed. The sample comprised eight community elders (four female, four male) and nine community members (six male, three female). A reference group comprising local community members and elders guided the research project. Results indicated that the communities’ main strength was their connection to culture, the areas most needing improvement were violence, alcohol use, over incarceration, poor support for mental health and a lack of employment opportunities. Participants saw the best way forward as being through more employment and better communication. The interconnectedness of these themes as well as their implications for successful program development and evaluation are discussed

Genomic organization and evolutionary conservation of plant D-type cyclins
Plants contain more genes encoding core cell cycle regulators than other organisms but it is unclear whether these represent distinct functions. D-type cyclins (CYCD) play key roles in the G1-to-S-phase transition, and Arabidopsis (Arabidopsis thaliana) contains 10 CYCD genes in seven defined subgroups, six of which are conserved in rice (Oryza sativa). Here, we identify 22 CYCD genes in the poplar (Populus trichocarpa) genome and confirm that these six CYCD subgroups are conserved across higher plants, suggesting subgroup-specific functions. Different subgroups show gene number increases, with CYCD3 having three members in Arabidopsis, six in poplar, and a single representative in rice. All three species contain a single CYCD7 gene. Despite low overall sequence homology, we find remarkable conservation of intron/exon boundaries, because in most CYCD genes of plants and mammals, the first exon ends in the conserved cyclin signature. Only CYCD3 genes contain the complete cyclin box in a single exon, and this structure is conserved across angiosperms, again suggesting an early origin for the subgroup. The single CYCD gene of moss has a gene structure closely related to those of higher plants, sharing an identical exon/intron structure with several higher plant subgroups. However, green algae have CYCD genes structurally unrelated to higher plants. Conservation is also observed in the location of potential cyclin-dependent kinase phosphorylation sites within CYCD proteins. Subgroup structure is supported by conserved regulatory elements, particularly in the eudicot species, including conserved E2F regulatory sites within CYCD3 promoters. Global expression correlation analysis further supports distinct expression patterns for CYCD subgroups

Evaluation and development of traffic control devices
"This project was established to provide a means of conducting small-scale research activities on an as needed basis so that the results could be available within months of starting the specific research. This report summarizes the small-scale research activities that were conducted between September 2008 and August 2009.
Responsibility and appropriate blame: The no difference view
How do the fact that an agent is morally responsible for a certain morally objectionable action and the fact that she is an appropriate target of blame for it relate to each other? Many authors inspired by Peter Strawson say that they necessarily co‐occur. Standard answers to the question of why they co‐occur say that the occurrence of one of the facts explains that the other obtains. This article presents a third option: that they are one and the same fact. There is no difference between the fact that a person is an appropriate target of blame for an objectionable action and the fact that she is morally responsible for it. This view has the advantage of being metaphysically more parsimonious and of answering, in an elegant and plausible way, an interesting question about which many standard theories of responsibility keep silent: what is it to be morally responsible simpliciter
