The Cost

The author develops a simulation model to estimate the optimum timing and maximum impact of full rehabilitation of New Zealand housing stock. The model is based on the theories of classical population dynamics. Data used in the model include empirical estimates of the mortality of New Zealand housing stock, assumed schedules of depreciation of dwelling services, and assumed schedules of annual maintenance costs. The dwelling service years provided by dwellings serve as a proxy for benefits of rents or imputed rents (excluding rent for land). The cost to construct one dwelling and fractions thereof serve as a proxy for costs of maintenance, rehabilitation, replacement, and new construction. Optimum timing of rehabilitation can increase the quantity of benefits provided by the housing stock per unit total cost but a reduction in the growth rate of new dwellings has a greater impact in achieving the same objective. A stationary and stable housing stock can provide 45% more dwelling services per unit total cost than a housing stock which doubles in size every 35 years.

Cost Components

Background: An ambulance is a vehicle designed to be able to handle emergency patients, provide first aid and carry out intensive care while on the way to a referral hospital. Ambulance operations require a large amount of funds obtained from APBD funds through tariffs that were passed through the DKI Jakarta Governor Regulation five years ago. For this reason, a new tariff is required to adjust to current conditions. Objectives: The purpose of this study is to calculate the unit cost of ambulance services in DKI Jakarta to be a consideration in the tariff setting policy in DKI Jakarta province. Research Metodes: This study uses a quantitative descriptive approach to obtain information about the unit cost of the Jakarta ambulance production unit. The method used is the calculation of real cost using the basis of the causes of costs. This research was conducted at the DKI Jakarta Emergency Ambulance using secondary data on investment costs, operational costs and maintenance costs in 2018. Results: The total cost of emergency ambulance in 2018 is known that the proportion of three cost components, namely operational costs, is 76%, followed by investment costs of 20% and maintenance costs of 3%. The calculation of the total cost of medical evacuation using the double distribution method is Rp. 98,915,016,805.00 divided by the number of medical evacuations in 2018 of 37,564 activities, the unit cost of medical evacuation for the AGD of DKI Jakarta Health Office is Rp. 2,633,215.00 without subsidies. APBD costs, while if the subsidy component is included in the calculation, the unit cost for one trip to the AGD of the Health Office is Rp. 604,071.00. This is still far above the current tariff of Rp. 450.00, so the cost recovery rate (CRR) is still below. 100%. Conclusion: From the three cost components consisting of investment, operational and maintenance costs,the largest proportion was operational costs at 76%. The Cost Recovery Rate has not reached 100% so that the existing rates have not covered the costs incurred.   Keywords: ambulance; price fixing; unit cost

Threatened Status

Despite the scarcity of funding for species conservation programmes, estimation of the cost of threatened species programmes occurs in only a few countries. This paper examines the reasons for the lack of species programme cost estimates and the likely impacts of this on conservation management. We report methodology used to estimate cost for eleven New Zealand species programmes and their estimated costs over a ten year period. Differences between species in the costs of the programmes and the breakdown of the costs are highlighted. The estimated costs are compared with expected levels of expenditure on each species to illustrate the existence of a budget constraint for threatened species. The likely effects of cost of species conservation exceeding expenditures on species conservation are examined. Annual cost data is used together with information on rate of conservation progress to estimate time and total cost for each species to reach Not Threatened status.

The Cost

It seemed very important to have a section on gas flow measurement. The UK's production of natural gas in 1984 was about 35×109 m3 and its consumption about 50×109 m3 with a reserve of about 0.7×1012 m3.* The value of this gas is 0.43 DM/m3† or about £0.12/m3 or about $0.18/m3. Unfortunately we were unable to find anyone able to write a section for this issue in the time available. However, I am grateful to Mr R J Simpson for drawing my attention to a report by Peignelin et al. † The authors have kindly agreed to an edited version of this paper. This paper considers two sizes of metering stations and considers the use of orifice or turbine meters. For these stations it considers investment costs and maintenance costs. It then examines the uncertainty in the energy content determination. The paper concludes that the major uncertainty lies in the flowmeter; that while turbine meter installations seem to be lower in cost than orifice meter installations, reliability must also be taken into account; and the cost of the instrumentation is a small proportion (15–20%) of the total cost of the station — R Baker.

Insight Into

Although anxiety and worry can motivate engagement with COVID-19 preventative behaviours, people may cognitively reframe these unpleasant emotions, restoring wellbeing at the cost of public health behaviours. New Zealand young adults ( n = 278) experiencing nationwide COVID-19 lockdown reported their worry, anxiety, reappraisal and lockdown compliance. Despite high knowledge of lockdown policies, 92.5% of participants reported one or more policy breaches ( M  = 2.74, SD = 1.86). Counter to predictions, no relationships were found between anxiety or worry with reappraisal or lockdown breaches. Findings highlight the importance of targeting young adults in promoting lockdown compliance and offer further insight into the role of emotion during a pandemic.

The Impact

SummaryPatient access to care and long wait times has been identified as major problems in outpatient delivery systems. These aspects impact medical staff productivity, service quality, clinic efficiency, and health-care cost.This study proposed to redesign existing patient types into scheduling groups so that the total cost of clinic flow and scheduling flexibility was minimized. The optimal scheduling group aimed to improve clinic efficiency and accessibility.The proposed approach used the simulation optimization technique and was demonstrated in a Primary Care physician clinic. Patient type included, emergency/urgent care (ER/UC), follow-up (FU), new patient (NP), office visit (OV), physical exam (PE), and well child care (WCC). One scheduling group was designed for this physician. The approach steps were to collect physician treatment time data for each patient type, form the possible scheduling groups, simulate daily clinic flow and patient appointment requests, calculate costs of clinic flow as well as appointment flexibility, and find the scheduling group that minimized the total cost.The cost of clinic flow was minimized at the scheduling group of four, an 8.3% reduction from the group of one. The four groups were: 1. WCC, 2. OV, 3. FU and ER/UC, and 4. PE and NP. The cost of flexibility was always minimized at the group of one. The total cost was minimized at the group of two. WCC was considered separate and the others were grouped together. The total cost reduction was 1.3% from the group of one.This study provided an alternative method of redesigning patient scheduling groups to address the impact on both clinic flow and appointment accessibility. Balance between them ensured the feasibility to the recognized issues of patient service and access to care. The robustness of the proposed method on the changes of clinic conditions was also discussed.

Vaccination Period

We analyze a mean field game model of SIR dynamics (Susceptible, Infected, and Recovered) where players choose when to vaccinate. We show that this game admits a unique mean field equilibrium (MFE) that consists in vaccinating at a maximal rate until a given time and then not vaccinating. The vaccination strategy that minimizes the total cost has the same structure as the MFE. We prove that the vaccination period of the MFE is always smaller than the one minimizing the total cost. This implies that, to encourage optimal vaccination behavior, vaccination should always be subsidized. Finally, we provide numerical experiments to study the convergence of the equilibrium when the system is composed by a finite number of agents ( $N$ ) to the MFE. These experiments show that the convergence rate of the cost is $1/N$ and the convergence of the switching curve is monotone.

Tests Of Hypotheses

One of the most common tools in New Zealand conservation is to translocate species to new locations. There have now been over 400 translocations done for conservation reasons, mainly involving terrestrial birds. Most translocations have been done strictly as management exercises, with little or no reference to theory. Nevertheless, translocations always involve some underlying theory, given that people must inevitably choose among a range of potential translocation strategies. We review theory relevant to translocations in the following areas: habitat requirements, susceptibility to predation, behavioural adaptation, population dynamics, genetics, metapopulation dynamics, and community ecology. For each area we review and evaluate the models that seem to underpin translocation strategies used in New Zealand. We report experiments testing some of these models, but note that theory underlying translocation strategies is largely untested despite a long history of translocations. We conclude by suggesting key areas for research, both theoretical and empirical. We particularly recommend that translocations be designed as experimental tests of hypotheses whenever possible.
