Long-Term Care Policy: Singapore’s Experience

Singapore, like many developed countries, is facing the challenge of a rapidly aging population and the increasing need to provide long-term care (LTC) services for elderly in the community. The Singapore government’s philosophy on care for the elderly is that the family should be the first line of support, and it has relied on voluntary welfare organizations (VWOs) or charities for the bulk of LTC service provision. For LTC financing, it has emphasized the principles of co-payment and targeting of state support to the low-income population through means-tested government subsidies. It has also instituted ElderShield, a national severe disability insurance scheme. This paper discusses some of the challenges facing LTC policy in Singapore, particularly the presence of perverse financial incentives for hospitalization, the pitfalls of over-reliance on VWOs, and the challenges facing informal family caregivers. It discusses the role of private LTC insurance in LTC financing, bearing in mind demand- and supply-side failures that have plagued the private LTC insurance market. It suggests the need for more standardized needs assessment and portable LTC benefits, with reference to the Japanese Long-Term Care Insurance program, and also discusses the need to provide more support to informal family caregivers.     

Parent physical punishment and child aggression in a Singapore Chinese preschool sample

We examine how parental physical punishment (caning and slapping) and child aggression are related, and possible moderation by authoritative control and rejection. A sample of 286 Singapore Chinese preschoolers ages 4–6 reported on rejection; their parents reported on control, caning, and slapping; and their teachers rated child aggression. Results show that father caning is related to aggression, regardless of child gender, whereas mother caning is related to child aggression only at low rejection. Mother slapping is related to sons’ aggression, whereas father slapping is related to daughters’ aggression only at low rejection. Control does not moderate any of the punishment‐aggression links. The punishment‐aggression link is thus a complex one, dependent on the dyad, the punitive act, and the parent's behavior.     

Property rights, collective sales and government intervention: averting a tragedy of the anticommons

In response to the need to cater for the requirements of a larger future population, the Urban Redevelopment Authority of Singapore released development guide plans, which have provided for higher development intensity to residential land in various parts of the island. One of the impacts is that many property owners in Singapore have banded together to capitalize on the “marriage value” of the en bloc site to reap big windfalls as compared to individual sales. But there were minority owners who objected to the sale. The Land Titles (Strata) (Amendment) Act 1999 was passed on 11 October 1999 to facilitate such en bloc sales as these will release prime land for higher density redevelopment to provide more quality private housing in land-scarce Singapore. This paper shows how property rights and property ownership could have led to a tragedy of the anticommons and how government intervention through legislation has averted such a tragedy. Whilst the Land Titles (Strata) (Amendment) Act 1999 has been successful in facilitating en bloc sales resulting in optimization of scarce land resources, it has raised controversial issues such as majority rule versus minority protection and the attenuation of property rights. The authors conclude that in land-scarce Singapore, public good, in that more land will be made available for private housing for the majority, should take precedence.     

Parameter Estimation for Discrete Distributions by Generalized Hellinger-Type Divergence Based on Probability Generating Function

This article considers a probability generating function-based divergence statistic for parameter estimation. The performance and robustness of the proposed statistic in parameter estimation is studied for the negative binomial distribution by Monte Carlo simulation, especially in comparison with the maximum likelihood and minimum Hellinger distance estimation. Numerical examples are given as illustration of goodness of fit.     

An Applied Comparison of Area-Level Linear Mixed Models in Small Area Estimation

This article reviews four area-level linear mixed models that borrow strength by exploiting the possible correlation among the neighboring areas or/and past time periods. Its main goal is to study if there are efficiency gains when a spatial dependence or/and a temporal autocorrelation among random-area effects are included into the models. The Fay–Herriot estimator is used as benchmark. A design-based simulation study based on real data collected from a longitudinal survey conducted by a statistical office is presented. Our results show that models that explore both spatial and chronological association considerably improve the efficiency of small area estimates.     

Physical workload during firefighting in Chilean volunteers

The study was performed in a sample of 39 firemen. The state of health for each fire fighter was evaluated by means of a clinical examination and also through some specific exams. Aerobic capacity was estimated as an indicator of physical fitness. In each load, cardiac frequency and oxygen consumption were measured under a steady state condition. Additionally, body composition was calculated using a Tanita professional scale. Physical effort at work was determined by measuring cardiac frequency using a telemetric unit. Evaluations were carried out during night shifts, registering information under the following conditions: night shifts without emergency, fire simulation, training exercises and real fire fighting. In general terms, it is possible to state that fire fighters are healthy according to the result of the clinical examination. However, it is very important to highlight that 70% of the firemen consume alcohol and 80% were smokers. The average aerobic capacity of the sample was 2.6 l/min or 34.5 ml/kg/min. In terms of overweight and obesity, the body mass index was 25.7, whereas the percentage fat mass reached an average of 22.9 %. The cardiovascular load in the night shifts without emergencies did not surpass 40%, which in Chile is considered the highest limit for sustained work. However, during training, simulations and real fires, the firemen had higher cardiac frequencies, reaching peak levels close to 100% cardiovascular load.     

Statistical Analysis for the Inverse Trinomial Distribution

This article considers parameter estimation, goodness of fit, likelihood ratio and score tests, and model selection by Akaike information criterion for the inverse trinomial (IT) distribution, a classical one-dimensional random walk distribution. The IT distribution has a cubic variance function of the mean and is a generalization of the negative binomial distribution. Basic distributional properties and expressions for the probability mass function, recurrence formula, moments, and score functions are also presented.     

Social Optimal Location of Facilities with Fixed Servers,Stochastic Demand,and Congestion

We consider two capacity choice scenarios for the optimal location of facilities with fixed servers, stochastic demand, and congestion. Motivating applications include virtual call centers, consisting of geographically dispersed centers, walk‐in health clinics, motor vehicle inspection stations, automobile emissions testing stations, and internal service systems. The choice of locations for such facilities influences both the travel cost and waiting times of users. In contrast to most previous research, we explicitly embed both customer travel/connection and delay costs in the objective function and solve the location–allocation problem and choose facility capacities simultaneously. The choice of capacity for a facility that is viewed as a queueing system with Poisson arrivals and exponential service times could mean choosing a service rate for the servers (Scenario 1) or choosing the number of servers (Scenario 2). We express the optimal service rate in closed form in Scenario 1 and the (asymptotically) optimal number of servers in closed form in Scenario 2. This allows us to eliminate both the number of servers and the service rates from the optimization problems, leading to tractable mixed‐integer nonlinear programs. Our computational results show that both problems can be solved efficiently using a Lagrangian relaxation optimization procedure.     

Webster‐Stratton Incredible Years Basic Parent Programme (IY) in child care placements: residential staff carers' satisfaction results

The aim of the present study was to investigate residential child care staff satisfaction with their involvement in the Webster‐Stratton Incredible Years Basic Parent Programme (IY). In an exploratory, not randomized study, 27 professionals from two different short‐term Portuguese residential child care centres (IG1, n = 15; IG2; n = 12) completed weekly IY evaluations and an overall satisfaction questionnaire at the end of their participation in the IY intervention. The weekly level of satisfaction was assessed with regard to each of the programme's components (content, DVDs, group leaders, group discussion). At the last session, they filled out a questionnaire aimed to evaluate the levels of satisfaction regarding the programme overall, the teaching format, the group leader(s) and the usefulness of specific educational techniques they learned. Data indicated that residential staff carers were highly satisfied with the weekly sessions and with the overall usefulness of the intervention programme. Results are discussed in terms of implications and future research directions.
