    Abstract Background: Australia has made significant efforts in recent years to promote cycling.
    Methods: Trends in cyclist fatalities in Australia between 1991 and 2022, particularly in those aged 60 years and over, were examined using Poisson regression modelling.
    Results: Overall, cyclist fatalities decreased by 1.1% annually. However, while there was an annual decline of 2.5% in those aged <60 years, fatalities in the 60+ age group increased by 3.3% annually. Mortality rates also showed an annual decrease of 3.5% for cyclists aged <60 years but remained almost stable in the 60+ age group over the study period. Single vehicle fatalities increased markedly, particularly among the 60+ age group (4.4% annually).
    Discussion: The observed increase in 60+ fatalities is due to the ageing of the population rather than a rise in cycling popularity as previously thought. The rise in single vehicle fatalities is likely to be related to the increase in the availability and use of dedicated cycling infrastructure.

    Abstract In low and middle-income countries like Ghana, private providers, particularly the grouping of faith-based non-profit health providers networked by the Christian Health Association of Ghana (CHAG), play a crucial role in maintaining service continuity during health worker strikes. Poor engagement with the private sector during such strikes could compromise care quality and impose financial hardships on populations, especially the impoverished. This study delves into the engagement between CHAG and the Government of Ghana (GoG) during health worker strikes from 2010-2016, employing a qualitative descriptive and exploratory case study approach. By analysing evidence from peer-reviewed literature, media archives, grey literature, and interview transcripts from a related study using a qualitative thematic analysis approach, this study identifies health worker strikes as a persistent chronic stressor in Ghana. Findings highlight some system-level interactions between CHAG and GoG, fostering adaptive and absorptive resilience strategies, influenced by CHAG's non-striking ethos, unique secondment policy between the two actors, and the presence of a National Health Insurance System. However, limited support from the government to CHAG member facilities during strikes and systemic challenges with the National Health Insurance System pose threats to CHAG's ability to provide quality, affordable care. This study underscores private providers' pivotal role in enhancing health system resilience during strikes in Ghana, advocating for proactive governmental partnerships with private providers and joint efforts to address human resource-related challenges ahead of strikes. It also recommends further research to devise and evaluate effective strategies for nations to respond to strikes, ensuring preparedness and sustained quality healthcare delivery during such crises.

    Abstract Understanding the behavior of surfactants at interfaces is crucial for many applications in materials science and chemistry. Optical tweezers combined with trajectory analysis can become a powerful tool for investigating surfactant characteristics. In this study, we perform trap-and-track analysis to compare the behavior of cetyltrimethylammonium bromide (CTAB) and cetyltrimethylammonium chloride (CTAC) at water-glass interfaces. We use optical tweezers to trap a gold nanoparticle and statistically analyze the particle's movement in response to various surfactant concentrations, evidencing the rearrangement of surfactants adsorbed on glass surfaces. Our results show that counterions have a significant effect on surfactant behavior at the interface. The greater binding affinity of bromide ions to CTA+ micelle surfaces reduces the repulsion among surfactant head groups and enhances the mobility of micelles adsorbed on the interface. Our study provides valuable insights into the behavior of surfactants at interfaces and highlights the potential of optical tweezers for surfactant research. The development of this trap-and-track approach can have important implications for various applications, including drug delivery and nanomaterials.

    Abstract Background: Spurred by the WHO's endorsement of universal health coverage as a goal of all health systems, many countries are undertaking health financing reforms. The nature of these reforms, and the policy processes by which they are achieved, will depend on context-specific factors, including the history of reform efforts and the political imperatives driving reforms. South Africa's pursuit of universal health coverage through a National Health Insurance is the latest in a nearly 100-year history of health system reform efforts shaped by social and political realities.
    Methods: We conducted an interdisciplinary, retrospective literature review to explore how these reform efforts have unfolded, and been shaped by the contextual realities of the moment. We began the review by identifying peer-reviewed literature on health system reform in South Africa, and iteratively expanded the search through author tracking, citation tracking and purposeful searches for material on particular events or processes referenced in the initial body of evidence. Data was extracted and organised chronologically into nine periods.
    Results: The analysis suggests that in South Africa politics; the power of the private sector; competing policy priorities and budgetary constraints; and ideas, values and ideologies have been particularly important in constraining, and sometimes spurring, health system reform efforts. Political transitions and pressures - including the introduction of apartheid in 1948, anti-apartheid opposition, the transition to democracy, and corruption and governance failures - have alternately created political imperatives for reform, and constrained reform efforts. In addition, the country's political history has given rise to dominant ideas, values and ideologies that imbue health system reform with a particular social meaning. While these ideas and values increase opposition and complicate reform efforts, they also help to expose the inequities of the current system as problematic and re-emphasise the need for reform.
    Conclusion: Ultimately, this analysis demonstrates the context-specific nature of health system reform processes and the influence of history on what sorts of reforms are politically feasible and socially acceptable, even in the context of a global push for universal health coverage.

    Abstract Electromagnetic forces and torques enable many key technologies, including optical tweezers or dielectrophoresis. Interestingly, both techniques rely on the same physical process: the interaction of an oscillating electric field with a particle of matter. This work provides a unified framework to understand this interaction both when considering fields oscillating at low frequencies─dielectrophoresis─and high frequencies─optical tweezers. We draw useful parallels between these two techniques, discuss the different and often unstated assumptions they are based upon, and illustrate key applications in the fields of physical and analytical chemistry, biosensing, and colloidal science.

    Abstract Hymenopterans, such as bees and wasps, have long fascinated researchers with their sinuous movements at novel locations. These movements, such as loops, arcs, or zigzags, serve to help insects learn their surroundings at important locations. They also allow the insects to explore and orient themselves in their environment. After they gained experience with their environment, the insects fly along optimized paths guided by several guidance strategies, such as path integration, local homing, and route-following, forming a navigational toolkit. Whereas the experienced insects combine these strategies efficiently, the naive insects need to learn about their surroundings and tune the navigational toolkit. We will see that the structure of the movements performed during the learning flights leverages the robustness of certain strategies within a given scale to tune other strategies which are more efficient at a larger scale. Thus, an insect can explore its environment incrementally without risking not finding back essential locations.
