Language Change in a Post-Creole, British Contact Setting: Non-Standard Ain’t Negation

The word ain't is used by speakers of all dialects and sociolects of English. Nonetheless, language critics view ain't as marking speakers as "lazy" or "stupid"; and the educated assume ain't is on its deathbed, used only in cliches. Everyone has an opinion about ain't. Even the grammar-checker in Microsoft Word flags every ain't with a red underscore. But why? Over the past 100 years, only a few articles and sections of books have reviewed the history of ain't or discussed it in dialect contexts. This first book-length collection specifically dedicated to this shibboleth provides a multifaceted analysis of ain't in the history and grammar of English; in English speech, writing, television, comics and other media; and in relation to the minds, attitudes, and usage of speakers and writers of English from a range of regions, ethnicities, social classes, and dialect communities. Most articles in the collection are accessible for the average educated speaker, while others are directed primarily at specialists in linguistic study-but with helpful explanations and footnotes to make these articles more approachable for the layperson. This collection of articles on ain't thus provides a broad audience with a rich understanding and appreciation of the history and life of this taboo word

As well as being a democratic outrage, first past the post also has additional unseen consequences

It is an article of faith amongst political reform campaigners that the existing First Past the Post (FPTP) electoral system needs to go if we are to improve Britain’s democracy. Here, Ed Straw describes the ‘unseen consequences’ of FPTP, and suggests that organisations such as Office for National Statistics and the Institute For Fiscal Studies to estimate these costs

Contrast sensitivity of insect motion detectors to natural images

How do animals regulate self-movement despite large variation in the luminance contrast of the environment? Insects are capable of regulating flight speed based on the velocity of image motion, but the mechanisms for this are unclear. The Hassenstein–Reichardt correlator model and elaborations can accurately predict responses of motion detecting neurons under many conditions but fail to explain the apparent lack of spatial pattern and contrast dependence observed in freely flying bees and flies. To investigate this apparent discrepancy, we recorded intracellularly from horizontal-sensitive (HS) motion detecting neurons in the hoverfly while displaying moving images of natural environments. Contrary to results obtained with grating patterns, we show these neurons encode the velocity of natural images largely independently of the particular image used despite a threefold range of contrast. This invariance in response to natural images is observed in both strongly and minimally motion-adapted neurons but is sensitive to artificial manipulations in contrast. Current models of these cells account for some, but not all, of the observed insensitivity to image contrast. We conclude that fly visual processing may be matched to commonalities between natural scenes, enabling accurate estimates of velocity largely independent of the particular scene

A `bright zone' in male hoverfly (Eristalis tenax) eyes and associated faster motion detection and increased contrast sensitivity

Eyes of the hoverfly Eristalis tenax are sexually dimorphic such that males have a fronto-dorsal region of large facets. In contrast to other large flies in which large facets are associated with a decreased interommatidial angle to form a dorsal `acute zone' of increased spatial resolution, we show that a dorsal region of large facets in males appears to form a `bright zone' of increased light capture without substantially increased spatial resolution. Theoretically, more light allows for increased performance in tasks such as motion detection. To determine the effect of the bright zone on motion detection, local properties of wide field motion detecting neurons were investigated using localized sinusoidal gratings. The pattern of local preferred directions of one class of these cells, the HS cells, in Eristalis is similar to that reported for the blowfly Calliphora. The bright zone seems to contribute to local contrast sensitivity; high contrast sensitivity exists in portions of the receptive field served by large diameter facet lenses of males and is not observed in females. Finally, temporal frequency tuning is also significantly faster in this frontal portion of the world, particularly in males, where it overcompensates for the higher spatial-frequency tuning and shifts the predicted local velocity optimum to higher speeds. These results indicate that increased retinal illuminance due to the bright zone of males is used to enhance contrast sensitivity and speed motion detector responses. Additionally, local neural properties vary across the visual world in a way not expected if HS cells serve purely as matched filters to measure yaw-induced visual motion

Redshift over Britain: is the Centre moving Left?

Is Jeremy Corbyn the new Centre in British politics? Ed Straw explains how years of privatisation, uncontrolled immigration, and deterioration in public services - combined with the lack of choice that comes with First Past the Post - all call for a leftward turn, and could rejuvenate the Labour Party

How weak governance stopped Labour winning the general election

Considering the turnaround in fortunes during and after the 2017 general election, why didn’t Labour win? The answer is to be found both in the Labour party’s governance, and in the whole system of British government, explains Ed Straw
