Pronunciation Instruction Can Improve L2 Learners\u27 Bottom-Up Processing for Listening

Listening is widely regarded as an important skill that is difficult and necessary to teach in L2 classrooms. Listening requires both top-down and bottom-up processing, yet pedagogical techniques for the latter are often lacking. This study explores the efficacy of pronunciation instruction (PI) for improving learners’ bottom-up processing. The study recruited 116 relatively novice learners of Spanish as a foreign language and provided the experimental groups with brief lessons in PI emphasizing segmental or suprasegmental features followed by production-focused or perception-focused practice. Learners’ bottom-up processing skill was assessed with a sentence-level dictation task. Learners given PI on suprasegmental features followed by perception-focused practice found target language speech to be more intelligible than controls, indicating that they had improved their bottom-up processing. However, learners given PI on segmental features followed by production-focused practice found target language speech to be more comprehensible. The results indicate that PI is a worthwhile intervention for reasons that go beyond pronunciation, even when instructional time is limited, and that a range of features and practice types should be included in PI to improve listening skills

The use of complementary and alternative medicine by 7427 Australian women with cyclic perimenstrual pain and discomfort: A cross-sectional study

© 2016 Fisher et al. Background: To assess the prevalence of cyclic perimenstrual pain and discomfort and to detail the pattern of complementary and alternative (CAM) use adopted by women for the treatment of these symptoms. Methods: Data from the 2012 national Australian Longitudinal Study of Women's Health (ALSWH) cross-sectional survey of 7427 women aged 34-39 years were analysed to estimate the prevalence of endometriosis, premenstrual syndrome (PMS), irregular or heavy periods and severe dysmenorrhoea and to examine the association between their symptoms and their visits to CAM practitioners as well as their use of CAM therapies and products in the previous 12 months. Results: The prevalence of endometriosis was 3.7 % and of the perimenstrual symptoms assessed, PMS was most prevalent at 41.2 % whilst irregular bleeding (22.2 %), heavy periods (29.8 %) and severe period pain (24.1 %) were reported at lower levels. Women with endometriosis were more likely than non-sufferers to have consulted with a massage therapist or acupuncturist and to have used vitamins/minerals, yoga/meditation or Chinese medicines (p < 0.05). PMS sufferers were more likely to consult with an osteopath, massage therapist, naturopath/herbalist or alternative health practitioner and to have used all forms of CAM therapies except Chinese medicines than women who had infrequent PMS (all p < 0.05). Women with irregular periods did not have different patterns of CAM use from non-sufferers and those with heavy periods did not favour any form of CAM but were less likely to visit a massage therapist or use yoga/meditation than non-sufferers (p < 0.05). For women with severe dysmenorrhoea there was no difference in their visits to CAM practitioners compared to non-sufferers but they were more likely to use aromatherapy oils (p < 0.05) and for more frequent dysmenorrhoea also herbal medicines, Chinese medicines and other alternative therapies compared to non-sufferers (all p < 0.05). Conclusions: There is a high prevalence of cyclic perimenstrual pain and discomfort amongst women in this age group. Women were using CAM differentially when they had specific symptoms of cyclic perimenstrual pain and discomfort. The use of CAM needs to be properly assessed to ensure their safe, effective use and to ascertain their significance as a treatment option enabling women with menstrual problems and their care providers to improve their quality of life

La pena de treballs en benefici de la comunitat : prevenció i gestió de les incidències en el seu compliment

Aquest estudi té com a objectiu explorar la prevenció i gestió d'incidències que duen a terme els delegats d'execució de mesures per tal d'aconseguir un compliment efectiu, per part dels penats a TBC. Així, a través del marc teòric es vol abordar el compliment en general per tal de comprendre la seva importància des de diferents perspectives així com els elements que la literatura científica mostra com a dificultats en el procés de compliment. El treball de camp recull les aportacions de delegades d'execució de mesures mitjançant una metodologia qualitativa.This study aims to explore the prevention and management of incidents carried out by probation officers aimed at the effective compliance, by those sentenced to community service. Thus, the theoretical framework aims to address compliance in general in order to understand its importance from different perspectives as well as the elements that the scientific literature shows as difficulties in the compliance process. The fieldwork collects the visions of probation officers using a qualitative methodology

Genome sequence of Yersinia pestis, the causative agent of plague.

The Gram-negative bacterium Yersinia pestis is the causative agent of the systemic invasive infectious disease classically referred to as plague, and has been responsible for three human pandemics: the Justinian plague (sixth to eighth centuries), the Black Death (fourteenth to nineteenth centuries) and modern plague (nineteenth century to the present day). The recent identification of strains resistant to multiple drugs and the potential use of Y. pestis as an agent of biological warfare mean that plague still poses a threat to human health. Here we report the complete genome sequence of Y. pestis strain CO92, consisting of a 4.65-megabase (Mb) chromosome and three plasmids of 96.2 kilobases (kb), 70.3 kb and 9.6 kb. The genome is unusually rich in insertion sequences and displays anomalies in GC base-composition bias, indicating frequent intragenomic recombination. Many genes seem to have been acquired from other bacteria and viruses (including adhesins, secretion systems and insecticidal toxins). The genome contains around 150 pseudogenes, many of which are remnants of a redundant enteropathogenic lifestyle. The evidence of ongoing genome fluidity, expansion and decay suggests Y. pestis is a pathogen that has undergone large-scale genetic flux and provides a unique insight into the ways in which new and highly virulent pathogens evolve
