In this study I examine the critical factors and themes that are identified as salient influencers of overt and relational aggression among youth. Sex differences and similarities associated with such adolescent perceptions are assessed. Forty-eight ethnically diverse youth between the ages of 14 and 16 years participated in sex-specific focus groups and individual interviews. Sex-Specific Syst...

In this paper, the concept of geo-referenced 3D map and its applications have been discussed. The major contribution is that it adopts geo-referenced images for various applications. Next generation 3D map, which is realistic, image-based, is able to provide 3D geometry measurements and various geo-location services. The methodology and development process has been introduced. Experiments for t...

The amount and availability of high-quality geo-spatial image data, such as digital satellite and aerial photographs, is increasing dramatically. Task-based management of such visual information and associated knowledge is a central concern for organisations that rely on digital imagery. We are developing geo-spatial knowledge management techniques that employ case-based reasoning as the core m...

Considering the increasing demand for developing alternative construction materials, due to the growing environmental concerns, this paper discusses the feasibility of alkali activated geo-polymer concrete, as a future construction material. The main objective of this study involves observation of structural behaviours of the fresh fly ash-based geo-polymer concrete, understanding the basic mix...

To date, use of the full potential of geo-information is not often applied in the daily practice of policy makers. The main questions explored by this research are: Why is geo-information not widely used in policy and how can this be improved? A conceptual framework was developed to evaluate the use of geo-information. For five cases, the use of geo-information was evaluated by means of this fr...

Despite a lot of recent research, photogrammetric reconstruction from crowd-sourced imagery is plagued by a number of recurrent problems. (i) The resulting models are chronically incomplete, because even touristic landmarks are photographed mostly from a few “canonical” viewpoints. (ii) Man-made constructions tend to exhibit repetitive structure and rotational symmetries, which lead to gross er...

A geometric graph G is a simple graph G together with a straight line drawing of G in the plane with the vertices in general position. Two geometric realizations of a simple graph are geo-isomorphic if there is a vertex bijection between them that preserves vertex adjacencies and non-adjacencies, as well as edge crossings and non-crossings. A natural extension of graph homomorphisms, geo-homomo...

The objective of this research is to design an approach for selecting appropriate raw materials for facial tissues in Iran. There are three possibilities to maintain raw materials: (1) imported virgin pulp; (2) bagasse (sugar cane residue) plus some imported raw materials; and (3) recycled paper plus some imported raw materials. Owing to the shortage of raw materials as well as the high rate of...

As an important long-term incentive mode, the equity incentive promotes the managers to contribute to the interest uniformity of managers and shareholders. By using Paired-Samples T test methods and regression analysis method and choosing companies that issued the equity incentive plan in 2007 as the sample, this paper comparatively analyzes the differences in the performance of companies befor...
