The Future’s Path in Three Acadian French Varieties

In the present study, we investigate the expression of future temporal reference in three closely-related varieties of Atlantic Canada Acadian French, varieties which differ substantially in their sociolinguistic histories. The three communities (Baie Sainte-Marie, Nova Scotia; L’Anse-à-Canards, Newfoundland; and the Iles de la Madeleine, Quebec) have experienced varying types and degrees of dialect contact since their original settlement. At one end of the continuum, Baie Sainte-Marie had the most homogeneous settlement pattern and has been largely isolated from other French varieties, including other Acadian varieties, for several centuries. The Iles de la Madeleine is at the other extreme, involving the most heterogeneous mix of original settlers and a subsequent history which is defined by waves of dialect contact. In an intermediary position, L’Anse-à-Canard\u27s settlement history is less heterogeneous than that of the Iles de la Madeleine but did involve late 19th century dialect contact with European French. The study is based on linguistic data for speakers born between 1873 and 1925, which constitute some of the earliest audio recordings for the varieties, along with sociohistorical data drawn from nominal censuses, cadastral maps, family genealogies, etc. Our goal is to determine the extent to which the grammaticalization path of the periphrastic future (which would ultimately overtake the inflected future as the majority variant in other spoken varieties) would be mirrored in the three communities. The results of multivariate analyses show, for Baie Sainte-Marie, the earliest stage in the evolution of the periphrastic future: it is still associated with imminent contexts. For L’Anse-à-Canards, we see the strong association of the variant with proximal contexts more generally. For these two communities, then, the use of the periphrastic future has not spread to distal contexts. Finally, for The Iles de la Madeleine, we find some weakening of the temporal distance effect and the emergence of a polarity constraint not attested for the other Acadian communities: negative utterances are associated with the inflected future, a finding resembling that found in variationist research on varieties of Laurentian French, wherein the periphrastic future has become the general marker of futurity. We explain the acquisition of the polarity constraint in terms of contact with speakers of Laurentian varieties. In sum, the historical trajectory of the future variable is reflected in intercommunity variation for the earliest linguistic attestations for spoken Acadian French

Occurrence of the orange wheat blossom midge [Diptera :Cecidomyiidae] in Quebec and its incidence on wheat grain microflora

À l'été 1995, on a prélevé des échantillons de blé (Triticum aestivum) dans des champs de diverses régions agricoles du Québec. La présence de larves de la cécidomyie orangée du blé (Sitodiplosis mosellana) fut quantifiée et une évaluation qualitative et quantitative de la microflore des grains fut réalisée. Les pertes moyennes de rendement causées par les larves de la cécidomyie du blé furent estimée à 6,3%. Le pourcentage des épis infestés fut significativement corrélé avec la contamination bactérienne et fongique des grains (r = 0,79). La présence spécifique du Fusarium graminearum dans les grains de blé fut aussi significativement corrélée avec le nombre de larves par épi (r= 0,67) ou par épillet (r= 0,67). Il appert que la cécidomyie du blé pourrait jouer un rôle dans la dissémination du F. graminearum.Samples of wheat spikes (Triticum aestivum) were collected in the summer of 1995 from different crop districts in Quebec and the occurrence of orange wheat blossom midge (Sitodiplosis mosellana) and seed microflora were determined. Estimated yield loss caused by wheat midge larvae averaged 6.3%. The percentage of infested spikes was significantly correlated with total seed contamination by fungi and bacteria (r = 0.79). The specific occurrence of Fusarium graminearum in grains was also significantly correlated with number of larvae per spike (r = 0.67) or per spikelet (r = 0.67). Consequently, the wheat midge might play a role in dissemination of F. graminearum

Impact of ocean acidification on a key Arctic pelagic mollusc (Limacina helicina)

Thecosome pteropods (shelled pelagic molluscs) can play an important role in the food web of various ecosystems and play a key role in the cycling of carbon and carbonate. Since they harbor an aragonitic shell, they could be very sensitive to ocean acidification driven by the increase of anthropogenic CO2 emissions. The impact of changes in the carbonate chemistry was investigated on Limacina helicina, a key species of Arctic ecosystems. Pteropods were kept in culture under controlled pH conditions corresponding to pCO2 levels of 350 and 760 μatm. Calcification was estimated using a fluorochrome and the radioisotope 45Ca. It exhibits a 28% decrease at the pH value expected for 2100 compared to the present pH value. This result supports the concern for the future of pteropods in a high-CO2 world, as well as of those species dependent upon them as a food resource. A decline of their populations would likely cause dramatic changes to the structure, function and services of polar ecosystems

Intersecting motivations for leaving abusive relationships, substance abuse, and transactional sex among HIV high-risk women

Background: Women bear a significant burden of the HIV epidemic in the United States. Women classified as ‘HIV high-risk’ often bring co-existing histories of intimate partner violence (IPV), drug use, and transactional sex. To help inform future comprehensive HIV prevention strategies, we aimed to explore common motivating reasons and barriers to leaving and/or terminating engagement in each of these riskpromoting situations. Methods: Between August and November 2014, in-depth interviews were conducted with 14 HIV high-risk women in Atlanta, Georgia who had experienced IPV in the previous 12 months, and used drugs and/or engaged in transactional sex in the previous five years. Participants were asked about histories of IPV, drug use, and/or engagement in transactional sex, and the motivating reasons and barriers to terminating each. Results: Women reported a range of motivating reasons for leaving IPV, drug use, and transactional sex. Overlapping themes included impact on children, personal physical health/safety, and life dissatisfaction. Financial need was identified as a common barrier to leaving. Conclusions: Future HIV prevention research should further explore the perceived impact of IPV, drug use, and transactional sex on physical health/safety, life dissatisfaction, one’s children, and financial need as motivators and barriers to reducing upstream HIV risk

T-cell Growth Factor: Complete Nucleotide Sequence and Organization of the Gene in Normal and Malignant Cells

Using a cloned cDNA copy of T-cell growth factor (TCGF) mRNA from the Jurkat leukemic T-cell line, we have isolated three overlapping TCGF genomic clones from a human DNA library. The entire TCGF gene is contained within two adjacent EcoRI fragments spanning about 8 kilobases. The complete nucleic acid sequence was determined. The gene is divided into four exons. The 5\u27 untranslated region and the first 49 amino acids of the protein, 20 of which constitute a signal polypeptide and are not present in the secreted protein, are encoded by the first exon. Exons 2 and 3, separated from each other by a long intervening sequence, contain coding information for the next 20 and 48 amino acids, respectively. The remaining 36 amino acids and the 3\u27 untranslated region are contained in the fourth exon. A promoter sequence T-A-T-A-A-A is present 77 base pairs (bp) upstream from the translation initiation site, and a CAT homology region occurs 104 bp upstream from the initiation site. A putative site for initiation of mRNA transcription was identified 53 bp 5\u27 of the translation initiation codon. The organization of the gene was shown by Southern blot analysis to be identical in normal peripheral blood lymphocytes and in a variety of malignant lymphoid cell types. Restriction analysis of these cellular DNAs produced results exactly as predicted by the map for the cloned genomic TCGF, indicating that there is only a single copy of the human TCGF gene
