The relationship between EUV dimming and coronal mass ejections

Aims. There have been many studies of extreme-ultraviolet (EUV) dimming in association with coronal mass ejection (CME) onsets. However, there has never been a thorough statistical study of this association, covering appropriate temperature ranges. Thus, we make use of a large campaign database utilising the Coronal Diagnostic Spectrometer (CDS) and the Large Angle and Spectrometric COronagraph (LASCO) both on the SOlar and Heliospheric Observatory (SOHO) to associate dimming events detected at 1 and 2 million K with CME activity. The aim is to confirm whether the dimming-CME association is real or not. This in turn will confirm whether special attention should be paid to the EUV dimming in the pre-eruption and eruption periods to study the CME onset process itself. Methods. The CDS CME onset campaign data for Mg IX and FE XVI observations on the solar limb are used to compare to LASCO event lists over a period from 1998 to 2005. Dimming events are identified and the physical extent explored, whilst comparing the events to overlying CME activity. Results. For the identified dimming regions we have shown strong associations with CME onsets, with up to 55% of the dimming events being associated with CME activity. This is compared to the random case where up to 47% of the dimming regions are expected to be associated with CMEs. We have also shown that up to 84% of CMEs associated with our data can be tracked back to dimming regions. This compares to a random case of up to 58%. Conclusions. These results confirm the CME-EUV dimming association, using a statistical analysis for the first time. We discuss the repercussions for the study of CME onsets, i.e. analysis of the dimming regions and the periods up to such dimming may be key to understanding the pre-CME onset plasma processes. The results stress that one emission line may not be sufficient for associating dimming regions with CMEs

Ratbags on the fringe: Exploring feminism through crime

This dissertation considers how feminist crime fiction, can transform a traditionally male dominated genre. Contemporary feminist crime writers reject the codified masculine crime genre to create ever-expanding spaces for literary representation. I concentrate on three texts which are ordered as a progression. Firstly, I explore the conservative male. writing of Jennifer Rowe in The Makeover Murders. I then go on to The Life and Crimes of Harry Lavender by Marele Day which privileges a concern with the socio-political position of women and their access to socio-political power. The last text, Finola Moorhead\u27s Still Murder, is a radical work of feminist literature, as it critically engages with areas of French feminist theory, particularly that of Julia Kristeva, Helene Cixous and Luce Irigaray. These different strands of feminist thought signify a range of positions within the feminist movement. In my texts, however, I will argue that they become a mutually exclusive division. Different feminisms create certain limitations for women, and although I suggest how these limitations are reproduced in the texts, I argue nevertheless that The Life and Crimes of Harry Lavender and Still Murder in particular offer positive representations of contemporary women. In doing so, they signal a feminist use of genre which is non-structured and flexible, creating a range of possibilities for social and theoretical empowerment, for feminist writers and readers alike

Young children\u27s use of causal connections during storytelling : The role of context and individual differences in attention.

Narrative causal understanding is related to a variety of school-related skills such as reading comprehension, and memory. Previous research shows a developmental trend in the ability to use and understand causal connections that begins at age 4 and continually improves up through ages 10 and 11. Researchers posit that this developmental trend in one aspect of narrative ability is explained by an increase in narrative knowledge; children learn more about what is required in narratives they get older. There is a dearth of research on other possible influences on narrative ability. In two experiments, the current study uses a storytelling procedure to investigate narrative ability and causal understanding in 58 preschool children based on a conceptual model of early causal understanding in discourse. In the first experiment it was hypothesized that both individual and age-related differences will be observed in the complexity of causal connections children produce and the distance over which children causally connect. Variations in stimulus complexity (i.e., complexity of the goals of each story) were expected to account for differences in the production of causal connections. In the second experiment it was hypothesized that individual differences in skills related to three attention networks can explain differences in causal understanding. The results show that 3-year-olds can use causal connections during storytelling and that patterns of age-related increases differ depending on the connection type and narrative context. The results also show that attention skills influence specific aspects of causal understanding. The results are consistent with previous storytelling research and research with children diagnosed with ADHD. The current study illustrates the importance of investigating a variety of contextual and child factors that may impact the development of children\u27s causal understanding. Implications for future research and the development early intervention programs are discussed

If We’d Only Listen! What Research Can Tell Us About Aircrew Fatigue.

Performance decrements associated with fatigue are significant risk factors of occupational, motor vehicle, and aviation accidents. The substantial number of recent aviation occurrences involving aircrew fatigue and the slow progress of related rulemaking prompted the TSB to include fatigue management on its 2018 Watchlist of key safety issues. At the same time, a finding of aircrew fatigue in a 2017 NTSB investigation into a near-taxiway landing prompted some journalists to argue that there are few, if any, research studies showing how fatigue affects flying ability, and that current efforts in fatigue management may not be effective. This paper explores research in psychology where effects of fatigue on human performance were identified, and describes correlative changes in pilot performance, with a focus on the approach and landing phases of flight. Examples from recent TSB air transportation safety investigations are used to illustrate

Filicide: The Australian story

A filicide death, meaning the killing of a child by their parent or equivalent guardian, is a tragic event. Sadly, a UK study suggests Australia has the fourth highest rate of filicide among similar developed nations. Since Australian research studies on the incidence of filicide, or indeed on any other aspect of the problem, are limited, it is impossible to know if this finding is correct or not. However, in the last several years more research on filicide has emerged in Australia and by reviewing the recent research in detail, this article develops an integrated analysis of Australian filicide research and contributes to the knowledge bank on Australian filicide that can be used by professionals undertaking practice and research in intervention and prevention. Analysis of the studies shows one child dies at the hands of a parent every fortnight and that this number has not changed for many years. The analysis identifies the profiles of victims and perpetrators. The constellation of circumstances and stressors associated with each of the parental perpetrator groups is discussed, including the perpetrators’ contact with, and mostly unsuccessful use of, services. Based on the analysis, a way forward to prevention is propose

Establishing a Review Process to Evaluate Research Guides

Springshare\u27s LibGuide platform has become synonymous with online library pathfinders or research guides and instruction support. However, without oversight of the collection of guides and standards for their creation, unwieldy numbers and lack of uniformity prevail. The McGoogan Library of Medicine at the University of Nebraska Medical Center created a review process that not only governed the creation and approval of guides, but analyzed the usage and scope of guides that had already been created. This paper will outline the creation of standards and application of a review process to increase the value and relevance of guides
