The present study focuses on individual differences in levels of communicative anxiety (CA) and foreign language anxiety (FLA) in the first (L1), second (L2), third (L3) and fourth (L4) language of 106 adult language learners. Data were collected about CA / FLA levels when speaking with friends, with strangers, and speaking in public. The analyses revealed that multilinguals do experience more ...

The roles of flagella and five fimbriae (SEF14, SEF17, SEF21, pef, lpf) in the early stages (up to 3 days) of Salmonella enterica serovar Enteritidis (S. Enteritidis) infection have been investigated in the rat. Wild-type strains LA5 and S1400 (fim+/fla+) and insertionally inactivated mutants unable to express the five fimbriae (fim-/fla+), flagella (fim+/fla-) or fimbriae and flagella (fim-/fl...

In this issue (pp. 264–270), Hinman et al. review the results of economic evaluation studies of rubella vaccine published between 1970 and 2000. Most of the studies they include were designed to answer the question of whether the introduction of rubella vaccine into national immunization systems is economically justified. Five out of the 17 economic evaluation studies they used were carried out...

A rapid screening method for amber fla mutants of E. coli was devised and many mutants were obtained. In addition, strains with deletions of the fla genes in the his-uvrC region were isolated from high-temperature survivors of a lambda cI857 lysogen in which the prophage is located between his and fla. Utilizing these mutants, eleven fla genes (I--XI) and one hag gene were identified in the his...

Levi McNeil, Sookmyung Women’s University Previous research suggests that the affordances (van Lier, 2000) of asynchronous computer-mediated communication (ACMC) environments help reduce foreign language anxiety (FLA). However, FLA is rarely the focus of these studies and research has not adequately addressed the relationship between FLA and the affordances that students use. This study explore...

Two variants of Campylobacter jejuni IN1 differing in the expression of flagella, IN1 (Fla+ Mot+, wild type) and IN1-NM (Fla- Mot-), were tested for their ability to establish infection in adult hamsters. Animals were challenged intracecally with 2 X 10(9) to 5 X 10(10) CFU and monitored for evidence of infection. None of the challenged animals developed illness. There was a significant differe...

Several species of Legionella cause Legionnaires' disease (LD). Infection may occur through inhalation of Legionella or amoebal vesicles. The reservoirs of Legionella are water, soil, potting soil and compost. Some species of free-living amoebae (FLA) that are naturally present in water and soil were described as hosts for Legionella. This study aimed to understand whether or not the composting...

PURPOSE Recent insights regarding the pathogenesis of malignant pleural mesothelioma (MPM) provide new opportunities for targeted molecular therapies for this highly lethal disease. The present study was undertaken to examine the effects of the histone deacetylase inhibitor, Depsipeptide (DP) FK228, in conjunction with the cyclin-dependent kinase inhibitor, Flavopiridol (FLA), in cultured MPM c...
