Doubly duped males: the sweet and sour of the orchid's bouquet

Flowers of the orchid genus Ophrys resemble female insects, and thereby sexually deceive, attract and are pollinated by male insects. Floral bouquet is thought to play a major role in this sexual mimicry, although the search for functional odour components has been something of a chemical ecologist's Holy Grail. Two new papers unravel the exquisite intricacy of the chemical deception by the orchid.

Placing political economy: organising opposition to free trade before the abolition of the Corn Laws

The unfurling of global capitalism – and its attendant effects – has long been fertile intellectual terrain for geographers. But whilst studies of the processes and mechanisms of globalisation undoubtedly assume a talismanic importance in the discipline, geographers, with few exceptions, have left examinations of early economic liberalism to historians. One such critically important episode in the evolution of the liberal economic project was the repeal of the so-called 'Corn Laws' in 1846. Whilst the precise impact of the Manchester-based Anti-Corn Law League (ACLL) continues to be a matter of conjecture, Eric Sheppard has asserted that their particular take on political economy managed to assume a 'truth-like status' and worldwide universality. But the ACLL's campaign represents only one, albeit decisive, stage in the long intellectual and practical struggle between 'protectionists' and the disciples of free trade. Studies of the non-'Manchester' components have tended to focus squarely upon national politics. This paper examines a pivotal attempt in 1838 by Lord Melbourne's Government to experiment with the effective elimination of import duties on fresh fruit. Unlike most agricultural commodities, table fruit was produced in a tightly defined area, thus allowing the Government's experiment to play out, in theory, without national political fallout. Whilst the Government's clandestine actions left little time for a concerted opposition to develop, Kentish fruit growers soon organised. A formidable lobby was forged that drew wide local support yet also evolved beyond the original 'epistemic community'. Whilst the coalition failed in their efforts to reintroduce protective duties, their actions allow us to see how protectionist ideologies and policies were vivified through practices at many different spatial scales and to better understand the complex spatiality of protectionist takes on political economy. Their campaign also changed – at least in the short term – the course of British mercantile policy.

Green Owl and the Corn Maiden

Purpose: The purpose of this paper is to engage a different notion of feminism in accounting by addressing the issues of feminism, balance, and integration as a means of understanding differently the world for which one accounts. The ideas are communicated by the sharing of experiences through myth and storytelling.

Design/methodology/approach: An alternative lens for understanding the giving of accounts is proposed, drawing on earlier feminist accounting literature as well as storytelling and myth.

Findings: Including the subjective and intersubjective approaches to experiencing and understanding the world recommends an approach whereby both the feminine-intuitive and the masculine-rational processes are integrated in constructing decision models and accounts.

Research limitations/implications: Through an expanded view of values that can be included in reporting or recounting a different model is seen, and different decisions are enabled. The primary limitation is having to use words to convey one’s subjective and intersubjective understandings. The written medium is not the most natural language for such an undertaking.

Practical implications: By enabling the inclusion of more feminine values, a way is opened to engage more holistically with the society in which decisions are embedded.

Originality/value: Drawing on the storytelling tradition, a holistic model is suggested that can lead to emergence of a more balanced societal reporting.

Purple sweet potato colour - a potential therapy for galactosemia?

Galactosemia is an inherited metabolic disease in which galactose is not properly metabolised. There are various theories to explain the molecular pathology, and recent experimental evidence strongly suggests that oxidative stress plays a key role. High galactose diets are damaging to experimental animals and oxidative stress also plays a role in this toxicity which can be alleviated by purple sweet potato colour (PSPC). This plant extract is rich in acetylated anthocyanins which have been shown to quench free radical production. The objective of this Commentary is to advance the hypothesis that PSPC, or compounds therefrom, may be a viable basis for a novel therapy for galactosemia.

Classification the geographical origin of corn distillers dried grains with solubles by near infrared reflectance spectroscopy combined with chemometrics: A feasibility study

In this study, 137 corn distillers dried grains with solubles (DDGS) samples from a range of different geographical origins (Jilin Province of China, Heilongjiang Province of China, USA and Europe) were collected and analysed. Different near infrared spectrometers combined with different chemometric packages were used in two independent laboratories to investigate the feasibility of classifying geographical origin of DDGS. Base on the same dataset, one laboratory developed a partial least square discriminant analysis model and another laboratory developed an orthogonal partial least square discriminant analysis model. Results showed that both models could perfectly classify DDGS samples from different geographical origins. These promising results encourage the development of larger scale efforts to produce datasets which can be used to differentiate the geographical origin of DDGS and such efforts are required to provide higher level food security measures on a global scale.
