Antecedents and outcomes of consumer environmentally friendly attitudes and behaviour

With the intensification of problems relating to the environment, a growing number of consumers are becoming more ecologically conscious in their preferences and purchases of goods. This paper presents the results of a study conducted among 500 Cypriot consumers, focusing on the factors that shape consumer environmental attitudes and behaviour, as well as on the resulting outcomes. The findings confirmed that both the inward and outward environmental attitudes of a consumer are positively influenced by his/her degree of collectivism, long-term orientation, political involvement, deontology, and law obedience, but have no connection with liberalism. The adoption of an inward environmental attitude was also found to be conducive to green purchasing behaviour that ultimately leads to high product satisfaction. On the other hand, an outward environmental attitude facilitates the adoption of a general environmental behaviour, which is responsible for greater satisfaction with life. The findings of the study have important implications for shaping effective company offerings to consumers in target markets, as well as formulating appropriate policies at the governmental level to enhance environmental sensitivity among citizens

Transmission of Carbapenem-Resistant Klebsiella pneumoniae in US Hospitals

Background: Carbapenem-resistant Klebsiella pneumoniae (CRKp) is the most prevalent carbapenem-resistant Enterobacterales in the United States. We evaluated CRKp clustering in patients in US hospitals. Methods: From April 2016 to August 2017, 350 patients with clonal group 258 CRKp were enrolled in the Consortium on Resistance Against Carbapenems in Klebsiella and other Enterobacteriaceae, a prospective, multicenter, cohort study. A maximum likelihood tree was constructed using RAxML. Static clusters shared ≤21 single-nucleotide polymorphisms (SNP) and a most recent common ancestor. Dynamic clusters incorporated SNP distance, culture timing, and rates of SNP accumulation and transmission using the R program TransCluster. Results: Most patients were admitted from home (n = 150, 43%) or long-term care facilities (n = 115, 33%). Urine (n = 149, 43%) was the most common isolation site. Overall, 55 static and 47 dynamics clusters were identified involving 210 of 350 (60%) and 194 of 350 (55%) patients, respectively. Approximately half of static clusters were identical to dynamic clusters. Static clusters consisted of 33 (60%) intrasystem and 22 (40%) intersystem clusters. Dynamic clusters consisted of 32 (68%) intrasystem and 15 (32%) intersystem clusters and had fewer SNP differences than static clusters (8 vs 9; P =. 045; 95% confidence interval [CI]: -4 to 0). Dynamic intersystem clusters contained more patients than dynamic intrasystem clusters (median [interquartile range], 4 [2, 7] vs 2 [2, 2]; P =. 007; 95% CI: -3 to 0). Conclusions: Widespread intrasystem and intersystem transmission of CRKp was identified in hospitalized US patients. Use of different methods for assessing genetic similarity resulted in only minor differences in interpretation

Meta-analysis of type 2 Diabetes in African Americans Consortium

Type 2 diabetes (T2D) is more prevalent in African Americans than in Europeans. However, little is known about the genetic risk in African Americans despite the recent identification of more than 70 T2D loci primarily by genome-wide association studies (GWAS) in individuals of European ancestry. In order to investigate the genetic architecture of T2D in African Americans, the MEta-analysis of type 2 DIabetes in African Americans (MEDIA) Consortium examined 17 GWAS on T2D comprising 8,284 cases and 15,543 controls in African Americans in stage 1 analysis. Single nucleotide polymorphisms (SNPs) association analysis was conducted in each study under the additive model after adjustment for age, sex, study site, and principal components. Meta-analysis of approximately 2.6 million genotyped and imputed SNPs in all studies was conducted using an inverse variance-weighted fixed effect model. Replications were performed to follow up 21 loci in up to 6,061 cases and 5,483 controls in African Americans, and 8,130 cases and 38,987 controls of European ancestry. We identified three known loci (TCF7L2, HMGA2 and KCNQ1) and two novel loci (HLA-B and INS-IGF2) at genome-wide significance (4.15 × 10(-94)<P<5 × 10(-8), odds ratio (OR)  = 1.09 to 1.36). Fine-mapping revealed that 88 of 158 previously identified T2D or glucose homeostasis loci demonstrated nominal to highly significant association (2.2 × 10(-23) < locus-wide P<0.05). These novel and previously identified loci yielded a sibling relative risk of 1.19, explaining 17.5% of the phenotypic variance of T2D on the liability scale in African Americans. Overall, this study identified two novel susceptibility loci for T2D in African Americans. A substantial number of previously reported loci are transferable to African Americans after accounting for linkage disequilibrium, enabling fine mapping of causal variants in trans-ethnic meta-analysis studies.Peer reviewe

Comportamento de progênies oriundas de raças primitivas de algodão herbáceo frente ao ataque do bicudo Behavior of lines from cotton primitive race stocks to attack of the boll weevil

Com o objetivo de obter linhagens resistentes ao bicudo-do-algodoeiro (Anthonomus grandis Boheman), a Embrapa-Centro Nacional de Pesquisa de Algodão vem testando progênies oriundas de raças primitivas de algodoeiro herbáceo (Gossypium hirsutum L.) originárias do México e da América Central, que apresentam níveis aceitáveis de resistência ao bicudo. Em 1991 e 1992, as progênies em BC1F5 e BC1F6 oriundas das linhagens Texas 277, Texas 326 e Texas 1180, Texas 297, Texas 339, Texas 766 e Texas 1134, foram avaliadas com relação à resistência ao bicudo. O delineamento experimental utilizado foi o de blocos ao acaso, com seis repetições. A unidade experimental foi constituída por duas fileiras de 5 m, sob um espaçamento de 0,75 m x 0,20 m. As parcelas foram infestadas com adultos do bicudo recém-emergidos, a uma taxa de 10.000 adultos/ha. Aos seis dias após a liberação dos adultos, as parcelas foram pulverizadas com Cipermethrim, sendo realizadas em intervalos semanais. Foram procedidas cinco avaliações através da coleta de 33 botões florais ao acaso, por parcela. Os maiores níveis de resistência ao bicudo foram obtidos pelas progênies Texas 326-95-1, Texas 277-87-5, Texas 1180-99-2, Texas 297 e Texas 339, com redução de ataque de 44,0, 41,2, 32,0, 40,4 e 36,4%, respectivamente, em relação à testemunha CNPA 6H.<br>The goal of the boll weevil (Anthonomus grandis Boheman) resistance program of Embrapa-Centro Nacional de Pesquisa de Algodão is to obtain cultivars that give 80% suppression when compared to commercial cultivars. The primitive cottons (Gossypium hirsutum L.) from Mexico and Central America have been known to show measurable levels of resistance to the boll weevil. In 1991 and 1992, the lines in BC1F5 and BC1F6 from Texas 277, Texas 326, Texas 1180, Texas 297, Texas 339, Texas 766 and Texas 1134 were evaluated to boll weevil resistance. The experiment was carried out at Campina Grande, PB, Brazil. The trial utilized was RCB with six replications. The plots were infested with newly emerged adults at the rate of 10,000 adults/ha. Six days after adults were released, the plots were sprayed with Cipermethrim. Infestation counts started three weeks after the Cipermethrim application and were made at weekly intervals. Five infestation counts were conducted by collecting 33 squares at random from each plot. The highest levels of resistance occurred in Texas 326-95-1, Texas 277-87-5, Texas 1180-99-2, Texas 297 and Texas 339 with 44.0, 41.2, 32.0, 40.4 and 36.4% of attack reduction, respectively, in relation to control CNPA 6H
