    The sustainability of food production in Papua New Guinea
    (Cambridge University Press, 2022-01-01) Allen, Bryant J.; Bourke, R. Michael
    More than 80% of the people of Papua New Guinea (PNG) live in rural areas and produce most of the calories they consume. The rest comes from imported food, mainly rice and wheat. An estimated 83% of all food energy consumed in PNG in 2006 was derived from locally grown food. Rapid population change, an HIV/AIDS epidemic, and global climate change are the main threats to the sustainable production of this food into the future. Rapid population change threatens to bring about land degradation in shifting cultivation systems; also, HIV/AIDS will slow population growth but will selectively remove working-age people from the population, while the outcomes of global warming are less certain. Global warming is apparent in rises in temperatures and some observable changes in plant distributions. If global climate change increases the frequency of El Niño-Southern Oscillation (ENSO) events, then food production will be adversely affected. On the other hand, global warming may have some positive effects. Governance in PNG is poor, so rural people will have to face the outcomes of these three threats largely using their own resources of resilience, innovativeness, and hard work.

    Targeted interventions to improve discharge times in a cardiology department: a quality improvement project in Australia
    (2026-06-02) Xiong, Eddy; Da Silva, Dilki; Elsing, Mel; Perry, Donna; Eldridge, Mitch; Carberry, Angela; DeCourcy, Virginia; King, Zachary; Pleash, Jared; Helms, Anneline; Greaves, Kim
    Late discharges in cardiology inpatient units contribute to patient flow inefficiencies and poor patient outcomes. The authors conducted an interventional quality improvement study in an Australian cardiology inpatient unit over the course of 1 year, aiming to reduce the frequency of late discharges, defined as those that occur after 12:00 pm. Baseline mean discharge times were calculated over 1 month to identify causes of delays, then new departmental policies were created and implemented to improve discharge times, using the plan-do-check-act framework. Discharge outcomes were reassessed at 1 and 6 months post intervention. Key reasons for delayed discharge included delayed ward rounds and paperwork, or the requirement of review from another faculty. Interventions included formalising ward round commencement times, optimising discharge planning and enabling junior staff to more readily enact discharges. At 1 month post intervention, there was a significant reduction in the median discharge time of 87 minutes (95% CI 11–134 minutes, P<0.01). This was sustained at 6 months, with an 80-minute reduction compared to baseline (95% CI 23–130 minutes, P<0.01). This indicates that targeted interventions can improve discharge efficiency in cardiology inpatient units, enhancing patient flow and operational performance. This framework could potentially inform similar initiatives in other settings.

    Fabricating Ohmic contacts to Au hyperdoped Si for infrared photodetector applications
    (2026-03-01) Liu, Yining; Yang, Wenjie; Hadchiti, Peter; Hudspeth, Quentin; Agha, Imad; Sarangan, Andrew; Williams, James S.; Warrender, Jeffrey M.; Mathews, Jay
    Recently, hyperdoped Si has gained interest as an infrared material for photodetectors due to the possible formation of intermediate bands inside the Si band gap. In particular, Au-hyperdoped Si has been demonstrated to exhibit a sub-band gap photoresponse, but efficiencies remain low. To achieve high efficiency Au-hyperdoped Si (Si:Au) photo devices, we develop a recipe for Ohmic contact to Si:Au materials by understanding the properties of the interfacial region. In this work, we show that Si:Au can form an Ohmic contact, which is relatively independent of the contacting metal due to Fermi pinning behavior. Degenerate boron doping decreases the contact resistivity by 1 order of magnitude, because the Si:Au resistivity decreases immediately below the contact. Cr/Ni/Au 5/200/200 nm metal stacks with boron doping exhibit the lowest specific contact resistivity (0.16 Omega & sdot;cm2) in this work, better than Au-based contacts. We also demonstrate that the Cr silicide formation temperature causes the relocation of Au atoms and degrades sub-band gap behavior.
