One is not often called upon to review for a law journal a book which is not written either by a lawyer or specifically for a lawyer. Mr Stanley Brogden's Australia's Two-Airline Policy is such a book and its paper jacket states that the book is of particular interest for students of economics, public administration, business administration, political science and for general readers and libraries. Since, however, the Melbourne University Press is noted for its publication of serious and scholarly works, and further, because the two-airline policy cannot properly be understood without an adequate grasp of the legal and constitutional framework in which it operates, it seems quite proper to make an assessment of Mr Brogden's work. Mr Brogden is a very experienced aviation writer as the book will quickly demonstrate. It is the purpose of this review not only to assess the book on its merits but also to supplement the account of the two-airline policy by a closer examination of legal issues and some observations on the future implications of the policy.
The refusal of the High Court in Cooney v. Ku-ring-gai Municipal Council to follow Attorney-General (ex rei. Lumley) v. T. S. Gill & Son Ply Ltd should be received enthusiastically by public lawyers and others who consider that individuals should be restrained from breaking the law if their activities operate to the disadvantage of members of the public living in the vicinity. The long reign of Attorney-General v. Gill has ended. In Gill’s case in 1927 the Full Court of the Supreme Court of Victoria declined to grant the Victorian Attorney-General an injunction to restrain the defendant from continuing with the erection of a factory on land situated in a residential area contrary to a by-law of the City of Prahran. The Attorney-General had sought the injunction on the relation of Lumley, a ratepayer of the municipality, who alleged he was injuriously affected by the defendant’s acts which, according to the allegation, also amounted to an invasion of the rights of the ratepayers generally and of the public. The municipality had made no attempt to enforce its own by-law although an offence against the by-law could be punished by fines and continuing penalties.
The primary purpose of this article is to discuss the Australian statutory law applying to civil aviation. There will also be some consideration of one or two unresolved questions involving the application of common law rules, selected not only because of their intrinsic interest, but also because they are partly affected by Federal and State Acts of Parliament.
This study sought to assess undergraduate students’ knowledge and attitudes surrounding perceived self-efficacy and threats in various common emergencies in communities of higher education.
Methods
Self-reported perceptions of knowledge and skills, as well as attitudes and beliefs regarding education and training, obligation to respond, safety, psychological readiness, efficacy, personal preparedness, and willingness to respond were investigated through 3 representative scenarios via a web-based survey.
Results
Among 970 respondents, approximately 60% reported their university had adequately prepared them for various emergencies while 84% reported the university should provide such training. Respondents with high self-efficacy were significantly more likely than those with low self-efficacy to be willing to respond in whatever capacity needed across all scenarios.
Conclusions
There is a gap between perceived student preparedness for emergencies and training received. Students with high self-efficacy were the most likely to be willing to respond, which may be useful for future training initiatives.
Innovation is needed for the growing number of patients with chronic obstructive pulmonary disease (COPD). Pulmonary rehabilitation (PR) is effective in improving exercise tolerance and quality of life, but these benefits do not appear to be sustained. This highlights the need for cost effective methods to maintain benefits on completion of therapy. The findings of a large trial from the UK are reported.
Methods
A two-center randomized controlled trial of patients discharged from PR compared the costs and benefits of PR maintenance with standard care. National Health Service (NHS) resource use, personal expenditure, and societal costs were recorded over one year, and bottom-up costing was undertaken for the PR maintenance program. Changes in health-related quality of life were recorded using the EQ-5D-5L, and differences were compared with the level identified as significant for COPD. A cost utility analysis was undertaken from an NHS perspective; uncertainties in cost and outcome data were incorporated into a sensitivity analysis. Cost-effectiveness ratios and cost-effectiveness acceptability curves (CEACs) were computed.
Results
The study included 116 patients who had finished PR within the last four weeks. The economic analysis showed that mean healthcare costs per patient for PR maintenance were approximately GBP139.72 (EUR165.57) lower than for usual care. The observed 0.118 advantage in mean quality-adjusted life-years (QALYs) (p<0.05) was above the threshold (0.051) for COPD significance. CEACs indicated there was a 97 percent chance of achieving GBP20,000 (EUR23,699.80) per QALY (NICE acceptance level ≤GBP30,000 (EUR35,549.70). Patient and societal costs increased this percentage. It was estimated that if patients with COPD completed a maintenance program following PR, the NHS could save up to GBP28.6 million (EUR33.89 million).
Conclusions
Our findings confirm that a structured PR maintenance program is highly cost effective in extending the benefits of short-term PR. The trial, undertaken during COVID, also signals the potential for emerging digital innovations to provide future transformative change in delivering self-management programs to sustain health and reduce NHS costs for people living with chronic conditions.
Native aquatic macrophytes such as American eelgrass (Vallisneria americana Michx.) are often desirable in aquatic ecosystems due to the ecological benefits they provide but are threatened by competition from invasive taxa including non-native Vallisneria taxa and hydrilla [Hydrilla verticillata (L. f.) Royle]. Identifying potential selective herbicide management options can provide tools to minimize impacts to native taxa in restoration and aquatic invasive plant management programs. Greenhouse mesocosm experiments were conducted in 2023 to investigate herbicide efficacy on two native eelgrass species (V. americana and Vallisneria neotropicalis Vict.), two non-native taxa (Vallisneria australis S.W.L. Jacobs & Les and Vallisneria spiralis L. × Vallisneria denseserrulata Makino), and H. verticillata. Herbicide applications included endothall, diquat, florpyrauxifen-benzyl, fluridone, and flumioxazin and select combinations of these herbicides used in H. verticillata management. Endothall alone provided 90% to 100% aboveground biomass reduction at 3,000 µg L−1 with at least 24 h of continuous or intermittent exposure to all native and invasive species at 6 wk after exposure, whereas florpyrauxifen-benzyl applied alone resulted in minimal aboveground biomass reduction. A 45-d of exposure of fluridone (10 µg L−1) resulted in 95% biomass reduction of V. americana and 7% to 48% of other tested taxa. The combination of flumioxazin and florpyrauxifen-benzyl resulted in 90% to 100% aboveground biomass reduction, and endothall combined with florpyrauxifen-benzyl resulted in 93% to 100% aboveground biomass reduction across taxa. Reductions in belowground biomass mirrored trends observed in aboveground biomass. No treatments selectively controlled invasive Vallisneria without injury to native Vallisneria, although efficacy was observed on H. verticillata. These insights provide an understanding for differences between these Vallisneria for researchers moving forward with selectively targeting H. verticillata in the presence of native Vallisneria species and two new aquatic invasive plants. Future research should expand treatment scenarios, increase the study period, and identify potential integrated plant management strategies for field scenarios.
In retrospect, the dominant feature of the period 1966–70 was the virtual withdrawal of one of Australia’s great-power protectors, Britain, coupled with the new uncertainty over the long-term role of the other, the United States. By 1970 it was accepted that Australia faced a novel strategic situation, though there was no agreement on the appropriate response, nor had the debate on the implications of the new situation been very searching.
Mosquito-borne disease is a significant public health issue and within Australia Ross River virus (RRV) is the most reported. This study combines a mechanistic model of mosquito development for two mosquito vectors; Aedes vigilax and Aedes camptorhynchus, with climate projections from three climate models for two Representative Concentration Pathways (RCPs), to examine the possible effects of climate change and sea-level rise on a temperate tidal saltmarsh habitat in Perth, Western Australia. The projections were run under no accretion and accretion scenarios using a known mosquito habitat as a case study. This improves our understanding of the possible implications of sea-level rise, accretion and climate change for mosquito control programmes for similar habitats across temperate tidal areas found in Southwest Western Australia. The output of the model indicate that the proportion of the year mosquitoes are active increases. Population abundances of the two Aedes species increase markedly. The main drivers of changes in mosquito population abundances are increases in the frequency of inundation of the tidal wetland and size of the area inundated, increased minimum water temperature, and decreased daily temperature fluctuations as water depth increases due to sea level changes, particularly under the model with no accretion. The effects on mosquito populations are more marked for RCP 8.5 when compared to RCP 4.5 but were consistent among the three climate change models. The results indicate that Ae. vigilax is likely to be the most abundant species in 2030 and 2050, but that by 2070 Aedes camptorhynchus may become the more abundant species. This increase would put considerable pressure on existing mosquito control programmes and increase the risk of mosquito-borne disease and nuisance biting to the local community, and planning to mitigate these potential impacts should commence now.

Intimate partner violence (IPV) is a critical problem in the United States. Resource availability and cultural differences often exacerbate this problem for victims in rural communities. Despite this, very little research has focused exclusively on understanding the characteristics of IPV in rural communities; much scholarly research on this topic focuses on IPV occurring in urban environments. Some argue that the dearth of studies on rural IPV can be explained, in part, by social scientists, specifically criminologists, considering rural crime less important or serious than urban crime (Weisheit and Donnermeyer, 2000). At the same time, nearly all studies of IPV indicate violence against women occurs across all geographical locations, socioeconomic statuses and demographics (Breiding et al, 2015). Some research suggests women in rural areas experience higher rates of IPV and greater frequency of severe physical abuse than do their urban counterparts (Peek-Asa et al, 2011). Many of these differences can be explained by lack of access to resources, unwillingness of local law enforcement to intervene, and cultural and social norms in rural communities (Breiding et al, 2015). Even though a few studies have observed differences in IPV prevalence, frequency and severity by rurality, important gaps in knowledge exist regarding differences and similarities between rural and urban IPV (Lanier and Maume, 2009; Peek-Asa et al, 2011). To better understand these gaps, this chapter examines differences in incident characteristics of IPV against women in rural and urban locales.
This chapter uses incident-level crime victimisation data from the National Incident-Based Reporting System (NIBRS) and county-level data from the US Census Bureau's 2018 American Community Survey. Although not yet nationally representative due to lack of formal reporting requirements by law enforcement agencies, NIBRS is an ideal dataset to use because of its breakdown of crime incident data into distinct subcategories, which allows greater reporting specificity, and its more nuanced offence definitions compared to the previously used Summary Reporting System (SRS) (NIBRS, 2016). NIBRS helps law enforcement and researchers efficiently develop a clearer picture and deeper understanding of the patterns and characteristics of violence against women. NIBRS is especially useful for researchers interested in studying rural domestic violence as law enforcement agencies can be linked to Census population demographic information.
Invasive emergent and floating macrophytes can have detrimental impacts on aquatic ecosystems. Management of these aquatic weeds frequently relies upon foliar application of aquatic herbicides. However, there is inherent variability of overspray (herbicide loss) for foliar applications into waters within and adjacent to the targeted treatment area. The spray retention (tracer dye captured) of four invasive broadleaf emergent species (water hyacinth, alligatorweed, creeping water primrose, and parrotfeather) and two emergent grass-like weeds (cattail and torpedograss) were evaluated. For all species, spray retention was simulated using foliar applications of rhodamine WT (RWT) dye as a herbicide surrogate under controlled mesocosm conditions. Spray retention of the broadleaf species was first evaluated using a CO2-pressurized spray chamber overtop dense vegetation growth or no plants (positive control) at a greenhouse (GH) scale. Broadleaf species and grass-like species were then evaluated in larger outdoor mesocosms (OM). These applications were made using a CO2-pressurized backpack sprayer. Evaluation metrics included species-wise canopy cover and height influence on in-water RWT concentration using image analysis and modeling techniques. Results indicated spray retention was greatest for water hyacinth (GH, 64.7 ± 7.4; OM, 76.1 ± 3.8). Spray retention values were similar among the three sprawling marginal species alligatorweed (GH, 37.5 ± 4.5; OM, 42 ± 5.7), creeping water primrose (GH, 54.9 ± 7.2; OM, 52.7 ± 5.7), and parrotfeather (GH, 48.2 ± 2.3; OM, 47.2 ± 3.5). Canopy cover and height were strongly correlated with spray retention for broadleaf species and less strongly correlated for grass-like species. Although torpedograss and cattail were similar in percent foliar coverage, they differed in percent spray retention (OM, 8.5± 2.3 and 28.9 ±4.1, respectively). The upright leaf architecture of the grass-like species likely influenced the lower spray retention values in comparison to the broadleaf species.
Unoccupied aerial application systems (UAAS) are gaining popularity for weed management to increase applicator safety and to deliver herbicide treatments where treatment sites limit ground-based spray equipment. Several studies have documented UAAS application strategies and procedures for weed control in terrestrial settings, yet literature describing remote spray technology for use in aquatics remains limited. Currently, applicators seek guidance for UAAS deployment for aquatic weed management to overcome site access restrictions, deal with environmental limitations, and improve ground-based applicator safety in hazardous treatment scenarios. In the present case studies, we evaluate a consumer-available UAAS to deliver the herbicide, florpyrauxifen-benzyl, as both foliar and directed in-water spray applications. The first case study showed that the invasive floating-leaved plant, yellow floating heart, was controlled 80% to 99% by 6 wk after treatment (WAT) following UAAS foliar herbicide treatments. The second case study demonstrated that UAAS directed in-water herbicide application reduced variable-leaf watermilfoil visible plant material by 94% at 5 WAT. Likewise, directed in-water applications from UAAS eliminated the need to deploy watercraft, which improved overall operational efficiency. Data from both case studies indicate that UAAS can provide an effective and efficient treatment strategy for floating-leaved and submersed plant control among common herbicide treatment scenarios. Future integration of UAAS in aquatic weed control programs is encouraged, especially among smaller treatment sites (≤4 ha) or where access limits traditional spray operations.
Expanding the current aquatic herbicide portfolio, reducing total spray volumes, or remotely delivering herbicide using novel spray technologies could improve management opportunities targeting invasive aquatic plants, where options are more limited. However, research on giant salvinia (Salvinia molesta Mitchell) response to foliar herbicide applications at carrier volumes ≤140 L ha−1 is incomplete. Likewise, no data exist documenting S. molesta control with unoccupied aerial application systems (UAAS). Following the recent >100-ha incursion of S. molesta in Gapway Swamp, NC, a case study was developed to provide guidance for ongoing management efforts. In total, three field trials evaluated registered aquatic and experimental herbicides using a 140 L ha−1 carrier volume. Select foliar applications from UAAS were also evaluated. Results at 8 wk after treatment (WAT) indicated the experimental protoporphyrinogen oxidase inhibitor, PPO-699-01 (424 g ai ha−1), in combination with endothall dipotassium salt (2,370 g ae ha−1) provided 78% visual control, whereas control when PPO-699-01 (212 g ai ha−1) was applied alone was lower at 35%. Evaluations also showed diquat (3,136 g ai ha−1) alone, glyphosate (4,539 g ae ha−1) alone, and metsulfuron-methyl (42 g ai ha−1) alone achieved 86% to 94% visual plant control at 8 WAT. Sequential foliar applications of diquat, flumioxazin (210 g ai ha−1), and carfentrazone (67 g ai ha−1) at 6 wk following exposure to in-water fluridone treatments were no longer efficacious by 6 WAT due to plant regrowth. Carfentrazone applications made from a backpack sprayer displayed greater control than applications made with UAAS deploying identical carrier volumes at 2 WAT; however, neither application method provided effective control at 8 WAT. Additional field validation is needed to further guide management direction of S. molesta control using low carrier volume foliar applications.
The American Society of International Law (ASIL) is a globally important American professional non-governmental organization, organized by and for international lawyers as a learned society, and influential in its legal interpretations. For its first sixty years, it excluded African Americans. Subsequently, African Americans were allowed incremental but slowly widening participation, though they were still excluded from the American Journal of International Law (AJIL) Board of Editors. Divesting its stock portfolio to oppose apartheid was a reluctant step toward racial justice in 1986. The rise of a new minority-led racial critique of the Society produced, inter alia, the first African American AJIL Board member in 2014, followed by others. It also produced the adoption of the “Richardson Report,” which confirmed the early deliberate African American exclusion, and called for a reparations obligation to Black members. In 2020, new Society statements and priorities toward racial equity and diversity were added to a previous active Black task force (BASIL). However, the Society's transformation toward racial equity will depend upon its committed defiance of the current historic global white nationalist extremism which threatens to penetrate international law in America and the global community. This essay discusses ASIL's racial narratives from its origins of deep racial exclusion, through racial incrementalism to policy changes and reparations obligations toward greater equity, as it now confronts global white identity extremism.
We present a timeseries of 14CO2 for the period 1910–2021 recorded by annual plants collected in the southwestern United States, centered near Flagstaff, Arizona. This timeseries is dominated by five commonly occurring annual plant species in the region, which is considered broadly representative of the southern Colorado Plateau. Most samples (1910–2015) were previously archived herbarium specimens, with additional samples harvested from field experiments in 2015–2021. We used this novel timeseries to develop a smoothed local record with uncertainties for “bomb spike” 14C dating of recent terrestrial organic matter. Our results highlight the potential importance of local records, as we document a delayed arrival of the 1963–1964 bomb spike peak, lower values in the 1980s, and elevated values in the last decade in comparison to the most current Northern Hemisphere Zone 2 record. It is impossible to retroactively collect atmospheric samples, but archived annual plants serve as faithful scribes: samples from herbaria around the Earth may be an under-utilized resource to improve understanding of the modern carbon cycle.
