    This paper explores the theoretical understandings of supervisory neglect and how these understandings might assist in delivering practical responses using a public health approach to child protection.Injury is the leading cause of death in Australians 1–44 years of age (McClure, Stevenson, & McEvoy, 2004). Transport-related injury, drowning, and assault/homicide were the three leading causes of injury-related deaths in Australian children between 2004 and 2006 (AIHW, 2009). Children are particularly vulnerable to different types of injury depending on their stage of growth and development. This vulnerability is dependent on a combination of the child’s developmental stage, exposure to environmental risk factors and the presence of protective factors (Towner & Dowswell, 2002). Due to the diverse nature of injury in the population, prevention programs are mainly targeted at similar types of injury or circumstances in specific population groups. Examples of such targeted programs include preventing car crashes in newly licensed young drivers or educating beach goers to swim between the flags

    Citation: Bourne, Richard Franklin. A comparative study of the dentition of some common mammals. Senior thesis, Kansas State Agricultural College, 1903.Morse Department of Special CollectionsIntroduction: It is perhaps only natural that one who has made no special study of animal life, fails to realize fully the importance of the dental system. Not only are the teeth of animals vital to the species but also in many cases are they absolutely essential to the life of the individual. This of course is the most important factor in the consideration of the economy of teeth but not alone in this respect are they important. From the naturalist’s point of view, the dental system furnishes a very valuable and often the only means of classification and identification of animals both living and extinct. To go into this subject to any great depth one must first be thoroughly acquainted with the types with which he is dealing and even then, to make an exhaustive and scientific treatise on the subject one must give it close study and close observation for years. Therefore, in this necessarily brief discussion, we will confine ourselves to the working out of the most striking variations and peculiarities found in a few types with which we are most familiar. In only a few mammals are teeth entirely absent. In the whalebone whale the germs are found in the embryonic state but they never rise above the gums and disappear entirely before birth. The ant eaters and pangolins are examples of a few species in which no teeth are present in any stage. The young duck-bill has well developed molars but these have entirely disappeared in the adult animal. In many of the lower vertebrates the gradations from the horny skin of the head and jaws into well-defined teeth gives evidence of the nature of those organs and is sufficient, were no other evidence available, to classify teeth as modified dermal organs. Although they are present in many of the lower vertebrates, it is only in the mammals that they reach their highest development and are found definite in numbers, conformation and arrangement. In mammals these characteristics are comparatively fixed for any given species but in the different species we find wide variations

    Pre-Academy Placement in the Washington State Patrol: Factors Associated with Academy and Job Performance

    Get PDF
    Washington State Patrol Trooper Cadets serve in a number of positions, a number of locations across the state and for varying lengths of time before they are selected to attend the academy. The purpose of the present research was to determine whether these factors were related to subsequent academy performance and job performance. To that end, 255 cadets hired between 1979 and 1985 were studied. The results indicated that only pre-academy assignment duration was significantly correlated with academy completion and academy performance. Implications for further research and departmental policy are discussed

    Safeguarding youth from agricultural injury and illness: The Australian experience

    Get PDF
    [Extract] As of 31 March 2022, there were 25,890,773 estimated resident population in Australia across the eight states and territories (1). In the 2020–21 Financial year, there was 387 million hectares of agricultural land (50% of Australia's land mass), of which the majority (86%) was used for grazing (2). There were 228,372 people in the Australian agricultural workforce in 2016, 69% were males, the median age was 56 years, and a third (37%) were owner operators (3). In Australia, fatalities on Australian farms have remained steady over the last decade, with 1,584 between 2001–2020 (4). Children represent approximately 15% of these deaths (5, 6). Issues that have been found to be of importance to farmers about the safety of their children on farms in Australia include: general danger avoidance and safety, machinery, moving vehicles, bike safety, animal handling, personal protective equipment (PPE), supervision, speed, water safety and chemicals (5)

    Examining the Roles of PsToc75 POTRA Domains in Chloroplast Protein Import

    Get PDF
    During chloroplast formation via endosymbiosis most of the plastid genome was transferred to the host nuclear genome. Genomic and proteomic analysis suggests that \u3e95% of the original plastid proteome is now encoded in the nucleus, and these now cytosolically fabricated proteins require a post-translational transport pathway back into the organelle. This process is not well understood, yet it has been shown to involve translocons at the outer and inner envelope of the chloroplast membranes (TOC & TIC). These translocons interact with a cleavable N-terminal extension of between 20 and 100 residues on chloroplast-bound precursor proteins known as the transit-peptide. Precursor proteins pass through the outer membrane via the outer chloroplast membrane beta-barrel, Toc75. In addition to containing a transmembrane β-barrel, Toc75 also contains three polypeptide transport (POTRA) domain repeats at the N-terminus. Despite widespread occurrence the role of POTRAs is poorly understood. One possibility is that they function to promote either homo- or heterotypic protein:protein interactions. To investigate these possibilities, we modeled the psToc75 POTRA domains and purified recombinant POTRA domains. POTRA1, POTRA3, and POTRA1-3 have been used to investigate interactions. Homotypic POTRA interactions have been supported by crosslinking experiments and analytical ultra centrifugation (AUC). Crosslinking data shows POTRA1 and POTRA3 undergo oligimerization. AUC suggests that POTRA1 may homodimerize. Heterotypic interactions have been studied via pull-down assays, crosslinking, and AUC and demonstrate that POTRA1 and POTRA3 interact with transit peptide. Soluble POTRA1-3 seems to stimulate precursor protein import into isolated chloroplasts in an import assay. The role of POTRAs in guiding TOC assembly by homodimerization is being investigated, and experiments to establish how POTRAs aggregate are underway

    Epidemiology of Farm Injuries in New South Wales

    Injuries to people living and working on farms in New South Wales continue to be a significant burden on the health system, Workers’ Compensation system, agricultural industries and farming families. Strategies to reduce the number and severity of injuries suffered by farmers and people working on farms rely on accurate information. Unfortunately there is no one dataset available to describe the circumstances surrounding farm injuries and the size of this burden in Australia. Hence, a number of different data sources are required to provide a picture of farm injuries. To date, there has been very little critical examination of what value each of these datasets provides to describing farm injuries. This Thesis aimed to: • Undertake surveillance of injuries occurring to people on farms or during agricultural production in NSW using data from an Emergency Department, NSW Hospital Separations information, NSW Workers’ Compensation Claims, and ABS Deaths data. • Critically examine the utility of Emergency Department, Hospital, Workers’ Compensation, and ABS Deaths Data for the surveillance of farm injuries in NSW. • Critically examine data classification systems used in Emergency Department, Hospital, Workers’ Compensation, and ABS Deaths data collections to describe the breadth of farm injuries in NSW. • Define the priority areas for farm injury prevention initiatives in NSW based on the information obtained from the examination of the data from Emergency Department, Hospital, Workers’ Compensation, and ABS Deaths. • Evaluate the effectiveness of the NSW Rollover Protective Structure (ROPS) rebate scheme and examine the utility of the data currently available in NSW to measure the performance of the program. Four datasets, Tamworth Emergency Department, Hospital Separations, Workers’ Compensation and the Australian Bureau of Statistics (ABS) Deaths data were used to provide information on the surveillance of farm injuries, describe the breadth of classifications used to describe farm injuries, and define priorities for the prevention of farm injuries. There were 384 farm-related injuries which presented to the Emergency Department at the Tamworth Base Hospital between 1 September 1997 and 31 August 1998. Emergency Department data collected in this study used the Farm Injury Optimal Dataset (FIOD) for classification, which allowed for a comprehensive picture of the circumstances surrounding the injury event. The three most common external causes of injury were related to horses, motorcycles, and animals. Commonly people were working at the time of injury. Children represented 21% of the people injured. The average number of injuries per 100 farms per annum was 34.7. An examination of hospital discharge data for NSW was undertaken for the period 1 July 1992 to 30 June 2000 where the location of the injury was a farm. Classification of cases in this dataset conformed to the International Classification of Disease (ICD) versions 9 and 10. There were 14,490 people who were injured on a farm during the study period. The three most common external causes of injury were motorcycles, animals being ridden and agricultural machinery. Children represented 17% of all farm injury cases. The rate per 1,000 farms ranged from 19 to 42 per annum. An examination of Workers’ Compensation claims for agricultural industries in NSW between 1 July 1992 and 30 June 2001 was undertaken. The ‘Type of Occurrence’ classification system was used to code the claims. There were 24,332 claims of which the majority were males (82%). The incidence of injury / disease in agriculture per annum varied from 37 per 1,000 workers to 73 per 1,000 workers. The rate per 1,000 agricultural establishments varied from 54 to 76. The average cost of a claim was $10,880 and the average time lost per claims was 9.2 weeks. There were 81 deaths and 3,158 permanent disabilities. The three most common agents were sheep / goats (5%), ferrous and non-ferrous metals (5%), crates / cartons / boxes / etc (5%). Using ABS deaths data to examine the deaths of people working and living on farms was limited to males whose occupation was recorded as ‘farmer and farm manager’ and ‘agricultural labourer and related worker’. There were 952 deaths over the period 1 January 1991 and 31 December 2000. The information provided a consistent series of cases over time. Areas where prevention should be directed included motor vehicle accidents; falls; agricultural machinery; other machinery; firearms; poisoning; and drowning. Using any one of the datasets alone to examine people injured on farms not only underestimates the number of people injured, but also misses particular types of agents involved in farm injuries. Each of the datasets used in this Thesis provides a different perspective of farm injury in NSW. By examining the information together, there are a number of areas which are consistently represented in each dataset such as falls and agricultural machinery. While no one dataset provided all the information that would be useful for the prevention of injuries, the available information does provide direction for the development of prevention strategies. The overall weakness of the information provided is that it misses a number of risk factors that contribute to farm injuries such as fatigue and training. The lack of appropriate denominator information also makes it difficult to directly compare the datasets and estimate the size of the problem. There are a number of additional coding categories that could be included in each dataset that would provide a better understanding of the different groups at risk of sustaining an injury on a farm or during agricultural work. These coding categories include activity at time of injury, admission to hospital, and occupation. An example of the use of data to determine the effectiveness of a farm injury prevention program is the ‘NSW Rollover Protective Structure (ROPS) Rebate Scheme’ evaluation. Tractor rollover deaths have been identified as an issue for prevention by Farmsafe Australia; however, such deaths were not identified in any of the datasets used in this Thesis due to coding limitations in the ABS data. In this Thesis information about the evaluation of the ‘NSW ROPS Rebate Scheme’ is presented. The scheme was successful in fitting 10,449 ROPS to tractors and the following lessons were learnt: when providing a rebate, the administration (i.e. sending the cheque) needs to be done well; advertising is important and should be co-ordinated, increase the awareness of the risk(s) the intervention is aiming to prevent and effectiveness of subsequent solution (s); the program should ensure there is an increased awareness of the outcome the intervention is aiming to prevent; if regulation is part of the program, enforcement needs to undertaken; and should address any barriers to uptake. The information provided in this Thesis highlights the substantial burden that farm injury places on the agricultural and rural sector of NSW. While there is no one data source that can describe the circumstances and the burden of farm injuries, the currently available datasets do provide an insight into the circumstances of farm injuries and the burden these injuries place on health, Workers’ Compensation, agricultural industries and farming families
