City flight migration patterns in the East Midlands

This paper investigates migration to and from the Three Cities of Derby, Leicester and Nottingham. It investigates whether these cities lose more migrants than they gain from more rural parts of the city-regions and the extent to which these flows impact on the demographic profiles of the Three Cities

Opportunities for weed manipulation using GMHT row crops

The herbicides and cultivation systems available in most non-GM crops allow farmers little flexibility as to when they control weeds. However, glyphosate and glufosinate-ammonium, as used in GM herbicide tolerant crops, offer the opportunity to control large weeds and weed control can be timed according to the agronomic and environmental aims of the user. This paper will use sugar beet as a model crop and report results where different approaches to weed control have been used and discuss their relevance in the wider agricultural and environmental contextNon peer reviewe

A ratio model of perceived speed in the human visual system

The perceived speed of moving images changes over time. Prolonged viewing of a pattern (adaptation) leads to an exponential decrease in its perceived speed. Similarly, responses of neurones tuned to motion reduce exponentially over time. It is tempting to link these phenomena. However, under certain conditions, perceived speed increases after adaptation and the time course of these perceptual effects varies widely. We propose a model that comprises two temporally tuned mechanisms whose sensitivities reduce exponentially over time. Perceived speed is taken as the ratio of these filters' outputs. The model captures increases and decreases in perceived speed following adaptation and describes our data well with just four free parameters. Whilst the model captures perceptual time courses that vary widely, parameter estimates for the time constants of the underlying filters are in good agreement with estimates of the time course of adaptation of direction selective neurones in the mammalian visual system

Prosecutorial Discretion and the Death Penalty: An Integral Perspective

The prosecutor's choice to pursue the death penalty is one of the most momentous decisions he or she will face. Capital punishment represents the ultimate power of the state over its citizenry, and the decision to take the life of an offender is fraught with moral complexity. This paper reviews some of the extant literature on the US death penalty in general and the particular issue of decision-making for prosecutors. Further, we introduce discussion on how Wilber's Integral theory might be applied to the topic. We present aspects of Integral theory, including the four quadrant model and what Wilber refers to as the Basic Moral Intuition (BMI), as possible tools that may be used to navigate the ethical difficulties surrounding this decision-making process. We anticipate that delving into aspects of the Integral theory and contemplating on how they relate to concrete issues of criminal prosecution may assist CJ practitioners in how they might find pathways to resolutions of ethical quandaries
