Weed control through crop rotation has mainly been studied in a nonspatial context. However, weed seeds are often spread beyond the crop field by a variety of vectors. For weed control to be successful, weed management should thus be evaluated at the landscape level. In this paper we assess how seed dispersal affects the interactions between crop rotation and landscape heterogeneity schemes wit...

Three senior Chief Executives of acute hospital trusts in the UK recently visited the Northern Territory (NT) and South Australia (SA) to study remote and rural health care in general – and Aboriginal health in particular. As with all other aspects of Aboriginal life, the subject of health status is highly charged and generates heightened emotions and intense political debate across the country...

In criminology, the real life CSI currently faces an interesting phase, where mathematicians are entering the cold-blooded field of forensics. Geographic profiling uses existing geocoded data to predict, solve and prevent crime. In this study, we examine probability distance strategies and a Bayesian approach used to predict the residential location of a serial offender. We compare different di...

The study of serial killing has been dominated by an individualized focus on the aetiology and biography of particular offenders. As such, it has tended to downplay the broader social, historical and cultural context of such acts. This article addresses this lacuna by arguing that serial killers are distinctively modern. It highlights six modern phenomena related to serial killing: (a) the mass...

A field experiment was conducted to study the integrated weed management in groundnut (Arachis hypogaea L.) for consecutive three kharif seasons in 2010, 2011 and 2012 at Breeder Seed Production Farm of Orissa University of Agriculture and Technology, Bhubaneswar with 7 weed management treatments in four replications. Weed free check (two hand weeding at 20 and 40 DAS and manually uprooting of ...

Effect of weed competition periods on weeds and yield of black seed was studied through field experiments conducted at Agronomic Research Area, University of Agriculture, Faisalabad during winter 2006-07 and 2007-08. Weeds were allowed to compete with the crop for 40, 50, 60, 70, 80 days after sowing and throughout the growth season along with a weed free treatment. The data on weed density and...

Managing production environments in ways that promote weed community diversity may enhance both crop production and the development of a more sustainable agriculture. This study analyzed data of productivity of maize (corn) and soybean in plots in the Main Cropping System Experiment (MCSE) at the W. K. Kellogg Biological Station Long-Term Ecological Research (KBS-LTER) in Michigan, USA, from 19...
