OBJECTIVES To ascertain the views of trainees and recently graduated Fellows of the Royal Australian and New Zealand College of Obstetricians and Gynaecologists on their experiences of taking parental leave during specialist training. DESIGN An anonymous online survey, conducted over a 1-month period from 16 August 2012 to 14 September 2012, of participants' experiences of taking parental lea...
The study analyses of the “degree of association” between the satisfaction expressed by the parental figures and the family structure they belong to: Family nuclear, single-parent, binuclear and complex families. In the transversal investigation, 631 mothers and fathers from the middle and upper-middle socio-cultural class took part. The identification of the family structures was undertaken by...
The present investigation was undertaken to study the relationship of Academic Stress with parental aspirations and parental attitudes. Differences among boys and girls in science and humanities stream were studied with regard to academic stress and aspirations and attitudes of the parents of the adolescents. The sample of the study comprised of 120 students of both the sexes studying in twelft...
This paper presents findings on parent anxiety and attachment relationship style from the Deakin Family Options (DFO) pilot study, a randomized controlled pilot study comparing a family-based treatment (BEST Plus), versus a youth only treatment (CBT) versus a group who received both of these treatments (COMBINED). Eligible participants were families with a young person (aged 12 25 years) with a...
The major problems in transplanting the landscape trees are high level of mortality and low establishment rate of transplanted trees, especially in the first year. In order to achieve the best condition for successful transplanting of pine and plane trees in Isfahan landscape, the present study was carried out based on a completely randomized block design with four replicates and three treatmen...
The Asiatic oak weevil, Cyrtepistomus castaneus Roelofs (Coleoptera: Curculionidae), is a nonnative defoliator of trees in the Fagaceae family in the United States but has not been studied on Castanea species in the southern Appalachian Mountains. Planted trees of Castanea dentata (Marsh.) Borkh. (Fagales: Fagaceae), Castanea mollissima Blume (Fagales: Fagaceae), and four hybrid breeding genera...
A common problem in phylogenetics is to try to infer a species phylogeny from gene trees. We consider different variants of this problem. The first variant, called Unrestricted Minimal Episodes Inference, aims at inferring a species tree based on a model of speciation and duplication where duplications are clustered in duplication episodes. The goal is to minimize the number of such episodes. T...
Seed orchards are the key link between tree breeding and production forest for conifer trees. In Sweden, Scots pine Norway spruce seed currently supply ca. 85% of seedlings used in annual reforestation. The functionality these is thus crucial supporting long-term gain sustainable diversity. We conducted a large-scale genetic investigation across Sweden using genotyping-by-sequencing. genotyped ...
. Introduction Old trees are important and key elements of forest sites and are of great value in terms of forest management, reforestation, silviculture and ecology. Although old trees constitute a small percentage of forest trees, they account for a large share of forest carbon reserve and play a vital role in carbon storage. Understanding the how geographical and site distribution of thes...
