Evolution of resident bird breeding phenology in a landscape with heterogeneous resource phenology and carryover effects

It is generally expected that, in environments with pronounced seasonal resource peaks, birds’ reproductive success will be maximised when nestlings’ peak food demand coincides with the timing of high food availability. However in certain birds that stay resident over winter, earlier breeding leads juveniles to join the winter flock earlier, which by the prior residence effect increases their succ

Impact of inhaled corticosteroids on asthma hospitalization in Sweden

This paper has two purposes. The first is to examine whether increased medication of inhaled corticosteroids by asthmatic patients is correlated with an improvement in asthma control, measured as a reduction in asthma hospitalizations. The other purpose, if such a relationship can be established, is to analyse the economic consequences. Regional data on asthma hospitalization, i.e. number of bed-d

A pilot test of using the veil of ignorance approach to estimate a social welfare function for income

The veil of ignorance approach is tested as a basis for empirically determining the shape of the social welfare function for income. An experiment is carried out where the participants choose between different societies that differ with respect to per capita income and the distribution of income. The answers are analysed using logistic regression analysis. According to the results the respondents

Health care expenditure in the Nordic countries

International comparisons of health care expenditure are associated with many different kinds of problems. One type of problem is due to heterogeneous definitions and to difficulties with conversion to common prices. Such problems are present also if one selects homogeneous countries as, for example, the Nordic countries, which have a similar GDP per capita and social system. In this paper we comp

Drug Expenditure and New Drug Introductions : The Swedish Experience

This article measures the impact of the switch to new and more expensive drugs on the aggregate drug expenditure (both prescription and nonprescription) in Sweden during the period 1974 to 1991, and also on the disaggregated expenditure for 3 medical areas: asthma, hypertension and peptic ulcer disease. During the period studied, nominal drug expenditure increased 6-fold. The retail price index of

The impact of aging on health care expenditure in Sweden

This study measures the impact of aging on health care expenditure in Sweden in 1970-1985 and the projected impact for 1985-2005. In addition, the distribution of health care expenditure over different age groups is analysed. The study shows that changes in population aging account for barely 13% of the total increase in health care expenditure during the period 1970-1985, and that it is the combi

Willingness to pay for antihypertensive therapy - further results

A measurement experiment regarding willingness to pay for antihypertensive therapy is reported. A new type of binary willingness to pay question is used, that allows for different degrees of certainty with respect to the responses. Mean willingness to pay is derived from a simple expected utility model and estimated using maximum likelihood methods. The estimated parameters are highly significant,

Flow pulsation plays an important role for high-pressure homogenization in laboratory-scale

Most experimental and numerical investigations of high-pressure homogenizers assume that the valve is fed with a constant flowrate. However, technical homogenizers use piston pumps with either 3 or 5 pistons (production- and pilot-scale machines) or a single piston (laboratory-scale machines). This results in flow pulsation. It is still unknown to what extent this influences valve hydrodynamics. M

A pooled cross-section analysis of the health care expenditures of the OECD countries.

This paper has two purposes. The first, empirical purpose is to estimate and evaluate the effects of aggregate income, institutional and socio-demographic factors on health care expenditures in the OECD countries. The second purpose is methodological, and comprises assessment of temporal instability, the choice of functional form, and misspecification of the estimated relationships. Data compiled

Data for dynamics analysis of riverine dissolved organic carbon in Rukarara watershed, Rwanda

This data article presents water stage, flow, and net primary productivity (NPP) data that were used to analyze the dynamics of the riverine dissolved organic carbon (DOC) dynamics in the Rukarara River watershed in Rwanda. We measured water stage data every 15 min and calculated daily averages used to estimate flow based on rating curves. The rating curves were produced using several measured con

An econometric analysis of health care expenditure : A cross-section study of the OECD countries

This paper is an empirical examination of the determinants of aggregate health care expenditure. The paper presents a systematic analysis of relationships across 19 OECD countries, showing the effects of aggregate income, institutional and socio-demographic factors on health care expenditure. The results indicate that institutional factors of the health systems, in addition to per capita Gross Dom

Determinants of health care expenditure in Africa : A cross-sectional study

The paper presents some quantitative evidence on the relationship between certain socioeconomic and demographic factors and per capita health care expenditure in Africa. First, GNP per capita, percentage of births attended by health staff and foreign aid received per capita together explained 78.3% of the variance in health care expenditure. Second, per capita GNP is the most significant factor ex

Pooling international health care expenditure data

The purpose of this paper is twofold. The first is to analyse the statistical relationship between real health care expenditure per capita and aggregate income, public share in finance, age‐dependency ratio and inflation. The second purpose deals with methodological problems involved in pooling health care expenditure data. The empirical work is based on pooled cross‐sectional, time‐series data fo

Health care expenditure in Sweden - an international comparison

This paper analyses health care expenditure in Sweden and compares this with the corresponding expenditure In OECD countries. The definition and measurement problems of health care expenditure are discussed, new figures for the development of health care expenditure are presented and different measures of health care expenditure are provided. We found that health care expenditure has increased by

Conversion factor instability in international comparisons of health care expenditure

Parkin, McGuire and Yule (1987) (hereafter PMY) report that a regression of per capita health care expenditure on per capita income using different conversion factors (exchange rates, GDP PPPs, health PPPs) gave rise to different results. In this note we apply updated data to the same empirical relationship. In contrast to PMY, we find no noticeable conversion factor instability in that relationsh

Price and quantity in international comparisons of health care expenditure

An important omission from earlier cross-national comparisons of health care expenditure has been the failure to distinguish between price and quantity. Using recent data on purchasing power parities, the purpose of this article is to report some preliminary results regarding health care expenditure and quantity across 22 OECD countries. The article concludes that, contrary to what has been sugges

The antipyretic effect of paracetamol occurs independent of transient receptor potential ankyrin 1–mediated hypothermia and is associated with prostaglandin inhibition in the brain

The mode of action of paracetamol (acetaminophen), which is widely used for treating pain and fever, has remained obscure, but may involve several distinct mechanisms, including cyclooxygenase inhibition and transient receptor potential ankyrin 1 (TRPA1) channel activation, the latter being recently associated with paracetamol’s propensity to elicit hypothermia at higher doses. Here, we examined w

The influence of convection drying on the physicochemical properties of yacón (Smallanthus sonchifolius)

Yacón root is a natural source of fructans, which has many potential benefits. Convective drying has been applied to increase the shelf life of yacón roots. However, this processing may lead to detrimental effects on the physicochemical functionality. The drying was investigated using different conditions (drying temperatures of 45 °C, 50 °C and 55 °C at a drying air velocity of 2 m/s and 60 °C at

Deficiency of alkaline SMase enhances dextran sulfate sodium-induced colitis in mice with upregulation of autotaxin

Intestinal alkaline SMase (Alk-SMase) cleaves phosphocholine from SM, platelet-activating factor (PAF), and lysophosphatidylcholine. We recently found that colitis-associated colon cancer was 4- to 5-fold enhanced in Alk-SMase KO mice. Here, we further studied the pathogenesis of colitis induced by dextran sulfate sodium (DSS) in WT and KO mice. Compared with WT mice, KO mice demonstrated greater
