Existing literature analyzing the choice of received long-term care by frail elderly (65+ years) predominantly focuses on physical and psychological conditions of elderly people as factors that infl uence the decision for a particular type of care. Until now, however, the regional in-patient long-term care supply has been neglected as infl uential factor in the individual’s decision-making proc...

This paper considers the problem of parameter estimation in a model for a continuous response variable y when an important ordinal explanatory variable x is missing for a large proportion of the sample. Nonmissingness of x, or sample selection, is correlated with the response variable and/or with the unobserved values the ordinal explanatory variable takes when missing. We suggest solving the e...

In this paper we discuss parameter identification and likelihood evaluation for multinomial multiperiod Probit models. It is shown in particular that the standard autoregressive specification used in the literature can be interpreted as a latent common factor model. However, this specification is not invariant with respect to the selection of the baseline category. Hence, we propose an alternat...

Bioremediation techniques are being developed as substitutes for physical–chemical methodologies that expensive and not sustainable. For example, using the agricultural waste spent mushroom substrate (SMS) which contains valuable microbiota soil bioremediation. In this work, SMSs of four cultivated fungal species, Pleurotus eryngii, Lentinula edodes, ostreatus, Agaricus bisporus were evaluated ...

Amostras de ceras do ninho e da própolis de Apis mellifera foram analisadas. Observou-se a predominância de ésteres, seguidos de hidrocarbonetos. Os constituintes foram identificados por cromatografia a gás/espectrometria de massas. Amplas variações foram observadas nos padrões de hidrocarbonetos e dos ácidos e álcoois de ésteres. As cadeias carbônicas dos hidrocarbonetos abrangem a faixa C23 C...

We examine the determinants of low income transitions using first-order Markov models that control for initial conditions effects (those found to be poor in the base year may be a nonrandom sample) and for attrition (panel retention may also be non-random). Our econometric model is a form of endogeneous switching regression, and is fitted using simulated maximum likelihood methods. The estimate...

We explore the effects of income and, additionally education on the income, self-reported health and survival of people aged sixty-five and over in order to identify benefits resulting from education which are omitted in the conventional analysis with its focus on labour income excluding employer contributions. We find, for men, that income after the age of sixty-five is significantly influence...

In many stated preference settings stakeholders will be uncertain as to their exact willingness-topay for a proposed environmental amenity. To accommodate this possibility analysts have designed elicitation formats with multiple bids and response options that allow for the expression of uncertainty. We argue that the information content flowing from such elicitation has not yet been fully and e...

In order to analyze the genetic diversity and phylogenetic status of the Korean Chikso breed, we determined sequences of mtDNA cytochrome b (cyt b) gene and performed phylogenetic analysis using 239 individuals from 5 Chikso populations. Five non-synonymous mutations of a total of 15 polymorphic sites were identified among 239 cyt b coding sequences. Thirteen haplotypes were defined, and haplot...
