A behavioral comparison of male and female adults with high functioning autism spectrum conditions

Autism spectrum conditions (ASC) affect more males than females in the general population. However, within ASC it is unclear if there are phenotypic sex differences. Testing for similarities and differences between the sexes is important not only for clinical assessment but also has implications for theories of typical sex differences and of autism. Using cognitive and behavioral measures, we investigated similarities and differences between the sexes in age- and IQ-matched adults with ASC (high-functioning autism or Asperger syndrome). Of the 83 (45 males and 38 females) participants, 62 (33 males and 29 females) met Autism Diagnostic Interview-Revised (ADI-R) cut-off criteria for autism in childhood and were included in all subsequent analyses. The severity of childhood core autism symptoms did not differ between the sexes. Males and females also did not differ in self-reported empathy, systemizing, anxiety, depression, and obsessive-compulsive traits/symptoms or mentalizing performance. However, adult females with ASC showed more lifetime sensory symptoms (p = 0.036), fewer current socio-communication difficulties (p = 0.001), and more self-reported autistic traits (p = 0.012) than males. In addition, females with ASC who also had developmental language delay had lower current performance IQ than those without developmental language delay (p<0.001), a pattern not seen in males. The absence of typical sex differences in empathizing-systemizing profiles within the autism spectrum confirms a prediction from the extreme male brain theory. Behavioral sex differences within ASC may also reflect different developmental mechanisms between males and females with ASC. We discuss the importance of the superficially better socio-communication ability in adult females with ASC in terms of why females with ASC may more often go under-recognized, and receive their diagnosis later, than males.

NATO's security discourse after the Cold War: representing the West

This book provides a critical investigation into the discursive processes through which the North Atlantic Treaty Organisation (NATO)reproduced a geopolitical order after the end of the Cold War and the demise of its constitutive enemy, the Soviet Union.

Marguerite Duras and colonialist discourse: an intertextual reading of 'L'Empire français' and 'Un barrage contre le Pacifique'

This article examines the intertextual relationship between Marguerite Duras' pro-colonialist, propagandist text, L'Empire français (1943), and her seemingly anti-colonialist novel, Un barrage contre le Pacifique (1950). It explores both the transformative and the emulative uses to which descriptive elements, borrowed from the precursor text, are put in the novel's depictions of colonial Indochina. Going against prevalent critical readings of Barrage, the article highlights the ambivalent and ultimately only partial nature of Duras' apparent ideological volte-face

Blood pressure lowering effects of beetroot juice and novel beetroot enriched bread products in normotensive male subjects

A number of vegetables have a high nitrate content which after ingestion can be reduced to 36 nitrite by oral bacteria, and further to vasoprotective nitric oxide endogenously. Two separate 37 randomly controlled, single blind, cross-over, postprandial studies were performed in 38 normotensive volunteers. Ambulatory blood pressure was measured over a 24 h period 39 following consumption of either four doses of beetroot juice (BJ) 0 g, 100 g, 250 g and 500 g 40 (n = 18) or three bread products, control bread (0 g beetroot), red beetroot and white beetroot 41 enriched breads (n =14). Total urinary nitrate/nitrite (NOx) was measured at baseline, 2, 4 42 and 24 h post ingestion. BJ consumption significantly, and in a near dose dependent manner, 43 lowered systolic (P <0.01) and diastolic BP (P <0.001) over a period of 24 h, compared to 44 water control. Furthermore, bread products enriched with 100 g red or white beetroot lowered 45 systolic and diastolic BP over a period of 24 h (red beetroot enriched bread, P <0.05), with no 46 statistical differences between varieties. Total urinary NOx significantly increased following 47 consumption of 100 g (P<0.01), 250 g (P <0.001) and 500 g BJ (P <0.001) and after red 48 beetroot bread (P <0.05), but did not reach significance for white beetroot bread compared to 49 the no beetroot condition. These studies demonstrated significant hypotensive effects of a low 50 dose (100 g) of beetroot which was unaffected by processing, or the presence of betacyanins. 51 This data strengthens the evidence for cardioprotective BP lowering effects of dietary nitrate-52 rich vegetables.
