Sky Service: The Demands of Emotional Labour in the Airline Industry

Abstract: Following Hochschild's The Managed Heart, which emphasized the problematic features that emotional labour had for women flight attendants, a critical literature emerged which focused on the more enjoyable aspects of emotional labour in service employee experience. This article draws on this literature and analyses emotional labour as a gendered cultural performance but takes issue with the individualizing and pluralistic tenor in the post-Hochschild discussions. Using a qualitative and quantitative study of nearly 3000 Australian flight attendants, it focuses on organizational and occupational health and safety variables, as well as sexual harass-ment and passenger abuse — factors barely discussed by Hochschild's critics. The qualitative data indicate that emotional labour is both pleasurable and difficult at different times for the same individual. Gender is still pivotal, as Hochschild suggested, linking emotional labour with sexual harassment. At the same time, the most significant predictors from the quantitative study of whether emotional labour would be costly were organizational. Variables such as whether flight attendants felt valued by the company show that the airline management context is highly influential in the way in which emotional labour is experienced. As a means of understanding the complex relations in this important and eroticized area of service work where flight attendants, airline crews, airline management and passengers have convergent and conflicting interests, the article also deploys a new concept: ‘demanding publics’, to refer to trangressions of the legitimate boundaries of the service worker.

Risks of Primary Extracolonic Cancers Following Colorectal Cancer in Lynch Syndrome

Abstract: Background L ynch syndrome is a highly penetrant cancer predisposition syndrome caused by germline mutations in DNA mismatch repair (MMR) genes. We estimated the risks of primary cancers other than colorectal cancer following a diagnosis of colorectal cancer in mutation carriers. Methods W e obtained data from the Colon Cancer Family Registry for 764 carriers of an MMR gene mutation (316 MLH1, 357 MSH2, 49 MSH6, and 42 PMS2), who had a previous diagnosis of colorectal cancer. The Kaplan–Meier method was used to estimate their cumulative risk of cancers 10 and 20 years after colorectal cancer. We estimated the age-, sex-, country- and calendar period–specific standardized incidence ratios (SIRs) of cancers following colorectal cancer, compared with the general population. Results F ollowing colorectal cancer, carriers of MMR gene mutations had the following 10-year risk of cancers in other organs: kidney, renal pelvis, ureter, and bladder (2%, 95% confidence interval [CI] = 1% to 3%); small intestine, stomach, and hepatobiliary tract (1%, 95% CI = 0.2% to 2%); prostate (3%, 95% CI = 1% to 5%); endometrium (12%, 95% CI = 8% to 17%); breast (2%, 95% CI = 1% to 4%); and ovary (1%, 95% CI = 0% to 2%). They were at elevated risk compared with the general population: cancers of the kidney, renal pelvis, and ureter (SIR = 12.54, 95% CI = 7.97 to 17.94), urinary bladder (SIR = 7.22, 95% CI = 4.08 to 10.99), small intestine (SIR = 72.68, 95% CI = 39.95 to 111.29), stomach (SIR = 5.65, 95% CI = 2.32 to 9.69), and hepatobiliary tract (SIR = 5.94, 95% CI = 1.81 to 10.94) for both sexes; cancer of the prostate (SIR = 2.05, 95% CI = 1.23 to 3.01), endometrium (SIR = 40.23, 95% CI = 27.91 to 56.06), breast (SIR = 1.76, 95% CI = 1.07 to 2.59), and ovary (SIR = 4.19, 95% CI = 1.28 to 7.97). Conclusion Car riers of MMR gene mutations who have already had a colorectal cancer are at increased risk of a greater range of cancers than the recognized spectrum of Lynch syndrome cancers, including breast and prostate cancers.

Delayed versus Immediate Cord Clamping in Preterm Infants

Abstract: BackgroundThe preferred timing of umbilical-cord clamping in preterm infants is unclear. MethodsWe randomly assigned fetuses from women who were expected to deliver before 30 weeks of gestation to either immediate clamping of the umbilical cord (≤10 seconds after delivery) or delayed clamping (≥60 seconds after delivery). The primary composite outcome was death or major morbidity (defined as severe brain injury on postnatal ultrasonography, severe retinopathy of prematurity, necrotizing enterocolitis, or late-onset sepsis) by 36 weeks of postmenstrual age. Analyses were performed on an intention-to-treat basis, accounting for multiple births. ResultsOf 1634 fetuses that underwent randomization, 1566 were born alive before 30 weeks of gestation; of these, 782 were assigned to immediate cord clamping and 784 to delayed cord clamping. The median time between delivery and cord clamping was 5 seconds and 60 seconds in the respective groups. Complete data on the primary outcome were available for 1497 infants (...

Pore architecture of diatom frustules: Potential nanostructured membranes for molecular and particle separations

Abstract: Diatoms produce diverse three-dimensional regular silica structures with nanometer to micrometer dimensions and hold considerable promise for biological and biomimetic fabrication of nanostructured materials and devices In the present work, we describe the ultrastructural characterization of porous structures in diatom biosilica and discuss their potential as membrane filters for diffusion based separations The frustules of two centric diatom species, Coscinodiscus sp and Thalassiosira eccentrica, were investigated using scanning electron microscopy and atomic force microscopy Their morphological features, including pore size, shape, porosity, and pore organization, are described We observed that although pore organization in frustules of Thalassiosira eccentrica and Coscinodiscus sp is in reverse order, a striking commonality is the size range of the smallest pores in both species (around 40 nm) The consensus lower pore size suggests that frustule valves have a common function at this size of excluding viruses or other deleterious particles, and the pore size and organization is optimized for this purpose We suggest and implement an experimental approach to study the potential of diatom frustules for diffusive separation of molecular or nanoparticular components in microfluidic or lab-on-a-chip environments
