Adverse selection and moral hazard are commonly expected to cause market failures in natural disaster insurance markets. However, such problems may not arise if individuals mainly buy insurance based on risk preferences. Advantageous selection can occur if individuals with insurance are highly risk averse and seek to reduce risk. We offer a comprehensive empirical study of risk selection in nat...

OBJECTIVES This study used a person-environment (P-E) framework to examine individual capabilities and social and physical environmental attributes for their association with unmet assistance needs in activities of daily living (ADLs). Analyses were replicated among five ADLs (bathing, dressing, transferring, toileting, eating) and test the relative risk of apartment dwellers compared to those ...

Numerous studies have linked ambient air pollution and adverse health outcomes. Most studies of this nature relate outdoor pollution levels measured at a few monitoring stations with counts of health outcomes. Recently, computational methods have been developed to model the distribution of personal exposures, rather than ambient concentration, and then relate the exposure distribution to the he...

UNLABELLED The aim of this systematic review is to describe participation in social and physical leisure activities among children and adolescents with JIA, as well as identify potential determinants of leisure participation. METHODS Electronic databases were systematically searched for articles published up until June 2013 pertaining to participation in leisure activities among youth with JI...

The loss of preexisting genes or gene activities during evolution is a major mechanism of ecological specialization. Evolutionary processes that can account for gene loss or inactivation have so far been restricted to one of two mechanisms: direct selection for the loss of gene activities that are disadvantageous under the conditions of selection (i.e., antagonistic pleiotropy) and selection-in...

This paper studies how an institution such as markets affects the evolution of mankind. My key point is that the forces of natural selection are made weaker because trade allows people to specialize in those activities where they are strong, and to offset their weaknesses by purchasing adequate goods on the market. Absent trade, people must allocate their time among all the activities necessary...

The purpose of this study was to examine current trends in the use of activities by occupational therapists, to identify factors influencing their selection of activities, and to examine relationships between activities used and therapeutic goals. A questionnaire sent to 500 members of the American Occupational Therapy Association elicited a low response rate; thus, the results are descriptive ...

Given that children's exposure to gratitude-related activities may be one way that parents can socialize gratitude in their children, we examined whether parents' niche selection (i.e., tendency to choose perceived gratitude-inducing activities for their children) mediates the association between parents' reports of their own and their children's gratitude. Parent-child dyads (N =101; children ...

We have constructed a promoter selection vector for mycobacteria to analyze the sequences involved in mycobacterial transcriptional regulation. The vector pSD7 contains extrachromosomal origins of replication from Escherichia coli as well as from Mycobacterium fortuitum and a kanamycin resistance gene for positive selection in mycobacteria. The promoterless chloramphenicol acetyltransferase (CA...

background: replacment of cd133+ cell’s β globin gene by using a gene targeting construct containing the β globin gene and essential elements for homologous recombination. materials and methods: pfbggt was amplified, then digested using the nhei and xhoi restriction enzymes, and finally, a 13.3 kb band (naked dna) was extracted from the agarose gel. biological activity of positive and negative ...
