    One area in language and gender research that has so far received only little attention is the extent to which the sexes make use of what recent corpus research has termed “conversational grammar.” The author’s initial findings have suggested that the majority of features distinctive of conversational grammar may be used predominantly by female speakers. This article reports on a study designed to test the hypothesis that conversational grammar is “feminine grammar” in the sense that women’s conversational language is more adapted to the conversational situation than men’s. Based on data from the conversational subcorpus of the British National Corpus and following the situational framework for the description of conversational features elaborated in the author’s previous research, features distinctive of conversational grammar are grouped into five functional categories and their normed frequencies compared across the sexes. The functional categories distinguish features that can be seen as adaptations to constraints set by the situational factors of (1) Shared Context, (2) Co-Construction, (3) Real-Time Processing, (4) Discourse Management, and (5) Relation Management. The study’s results, described in detail in relation to the biological category of speaker sex and cultural notions of gender, suggest that the feminine grammar hypothesis is valid

    Time for a quick word? The striking benefits of training speed and accuracy of word retrieval in post-stroke aphasia

    One-third of stroke survivors experience deficits in word retrieval as a core characteristic of their aphasia, which is frustrating, socially limiting and disabling for their professional and everyday lives. The, as yet, undiscovered ‘holy grail’ of clinical practice is to establish a treatment that not only improves item naming, but also generalizes to patients’ connected speech. Speech production in healthy participants is a remarkable feat of cognitive processing being both rapid (at least 120 words per minute) and accurate (∌one error per 1000 words). Accordingly, we tested the hypothesis that word-finding treatment will only be successful and generalize to connected speech if word retrieval is both accurate and quick. This study compared a novel combined speed- and accuracy-focused intervention—‘repeated, increasingly-speeded production’—to standard accuracy-focused treatment. Both treatments were evaluated for naming, connected speech outcomes, and related to participants’ neuropsychological and lesion profiles. Twenty participants with post-stroke chronic aphasia of varying severity and subtype took part in 12 computer-based treatment sessions over 6 weeks. Four carefully matched word sets were randomly allocated either to the speed- and accuracy-focused treatment, standard accuracy-only treatment, or untreated (two control sets). In the standard treatment, sound-based naming cues facilitated naming accuracy. The speed- and accuracy-focused treatment encouraged naming to become gradually quicker, aiming towards the naming time of age-matched controls. The novel treatment was significantly more effective in improving and maintaining picture naming accuracy and speed (reduced latencies). Generalization of treated vocabulary to connected speech was significantly increased for all items relative to the baseline. The speed- and accuracy-focused treatment generated substantial and significantly greater deployment of targeted items in connected speech. These gains were maintained at 1-month post-intervention. There was a significant negative correlation for the speed- and accuracy-focused treatment between the patients’ phonological scores and the magnitude of the therapy effect, which may have reflected the fact that the substantial beneficial effect of the novel treatment generated a ceiling effect in the milder patients. Maintenance of the speed- and accuracy-treatment effect correlated positively with executive skills. The neural correlate analyses revealed that participants with the greatest damage to the posterior superior temporal gyrus extending into the white matter of the inferior longitudinal fasciculus, showed the greatest speed- and accuracy treatment benefit. The novel treatment was well tolerated by participants across the range of severity and aphasia subtype, indicating that this type of intervention has considerable clinical utility and broad applicability

    Impact of Anti-Inflammatory Agents on the Gene Expression Profile of Stimulated Human Neutrophils: Unraveling Endogenous Resolution Pathways

    Adenosine, prostaglandin E2, or increased intracellular cyclic AMP concentration each elicit potent anti-inflammatory events in human neutrophils by inhibiting functions such as phagocytosis, superoxide production, adhesion and cytokine release. However, the endogenous molecular pathways mediating these actions are poorly understood. In the present study, we examined their impact on the gene expression profile of stimulated neutrophils. Purified blood neutrophils from healthy donors were stimulated with a cocktail of inflammatory agonists in the presence of at least one of the following anti-inflammatory agents: adenosine A2A receptor agonist CGS 21680, prostaglandin E2, cyclic-AMP-elevating compounds forskolin and RO 20-1724. Total RNA was analyzed using gene chips and real-time PCR. Genes encoding transcription factors, enzymes and regulatory proteins, as well as secreted cytokines/chemokines showed differential expression. We identified 15 genes for which the anti-inflammatory agents altered mRNA levels. The agents affected the expression profile in remarkably similar fashion, suggesting a central mechanism limiting cell activation. We have identified a set of genes that may be part of important resolution pathways that interfere with cell activation. Identification of these pathways will improve understanding of the capacity of tissues to terminate inflammatory responses and contribute to the development of therapeutic strategies based on endogenous resolution

    Feasibility of using cold formed steel for medium span roof structures in Sri Lanka

    Cold formed steel members have been widely used in industrial and commercial buildings over the world with increasing interest and even in the residential development. In the past it was used mostly in non-load bearing structural systems that is partition and architectural feature elements, but it is now used even in the structural systems, and are effective in reducing the self-weight of structure. Cost of Construction around various parts of the world depends on various factors based on the structural category, availability of material, labour cost, material cost, technology available and use, serviceability limit requirements and standard structural design requirements, so on. Therefore light weight structure itself would not be an effective solution for every construction and structural system. Steel construction industry in Sri Lanka; mostly depends on hot rolled steel member / section for their structural solution. The other type of steel, that is cold formed sections / members available for construction, is very uncommon as a structural element, but it is still using as purlin, for steel roof structures. Feasibility of using cold formed steel in structural roof system has not been specifically studied yet, and construction industry is still waiting for such a detail study to overcome the excessive cost of steel construction in Sri Lanka. This research is based on the 4-case studies, that were already completed using hot rolled steel members for its structural roof system, contain 4.0m, 8.0m, 10.0m, & 12.0m span parallel girder trusses and pitched trusses. Bay spacing for selected cases were pre-defined according to the column grid of the particular building and was 3.0m, 4.0m, 3.2m, and 6.0m respectively. Under this study, aforesaid roof structures were totally replaced by cold formed steel system (lipped channel sections), and checked the structural ability to reach the design requirements followed by ultimate limit state and serviceability limit state, under feasible limit of cost
