Author Posting. © American Meteorological Society, 2009. This article is posted here by permission of American Meteorological Society for personal use, not for redistribution. The definitive version was published in Bulletin of the American Meteorological Society 90 (2009): 1337-1350, doi:10.1175/2009BAMS2706.1.A major oceanographic field experiment is described, which is designed to observe, quantify, and understand the creation and dispersal of weakly stratified fluid known as “mode water” in the region of the Gulf Stream. Formed in the wintertime by convection driven by the most intense air–sea fluxes observed anywhere over the globe, the role of mode waters in the general circulation of the subtropical gyre and its biogeo-chemical cycles is also addressed. The experiment is known as the CLIVAR Mode Water Dynamic Experiment (CLIMODE). Here we review the scientific objectives of the experiment and present some preliminary results.Physical

Toward Regional Characterizations of the Oceanic Internal Wavefield
Many major oceanographic internal wave observational programs of the last 4
decades are reanalyzed in order to characterize variability of the deep ocean
internal wavefield. The observations are discussed in the context of the
universal spectral model proposed by Garrett and Munk. The Garrett and Munk
model is a good description of wintertime conditions at Site-D on the
continental rise north of the Gulf Stream. Elsewhere and at other times,
significant deviations in terms of amplitude, separability of the 2-D vertical
wavenumber - frequency spectrum, and departure from the model's functional form
are noted. Subtle geographic patterns are apparent in deviations from the high
frequency and high vertical wavenumber power laws of the Garrett and Munk
spectrum. Moreover, such deviations tend to co-vary: whiter frequency spectra
are partnered with redder vertical wavenumber spectra. Attempts are made to
interpret the variability in terms of the interplay between generation,
propagation and nonlinearity using a statistical radiative balance equation.
This process frames major questions for future research with the insight that
such integrative studies could constrain both observationally and theoretically
based interpretations
Dominant culture and bullying : personal accounts of workers in Malaysia
Workplace bullying has been termed the cancer of the workplace; it is a widespread and often intractable problem. Internationally, a wealth of research has examined the prevalence of workplace bullying and its negative effects. This research base and the scientific definition of workplace bullying are, however, based on Western perspectives and supported by theories, models, and research studies conducted in Western cultures. The differences in cultural perspectives of Western and Eastern countries mean that workplace bullying may not be understood in the same way across different cultural groups, particularly when cultures differ along the Individualism-Collectivism dimension. Given that Malaysia is an Eastern country with a number of ethnic groups, a more comprehensive understanding of workplace bullying in the Malaysian context is important. Through a case study comprising in-depth qualitative interviews with 20 employees from different organisations in Malaysia, this chapter reveals six lay beliefs of workplace bullying and 19 lay beliefs about bullying behaviors. The study also found that the 12 bullying behaviors are work related while the other seven are personal-nature bullying behaviors. These results emphasize the influence of culture on how bullying is perceived within the Malaysian context, and the importance of understanding lay representations of workplace bullying from the Eastern context that apparent across nation. Based on the interviews, a general definition of workplace bullying from Malaysian employees' perspectives is presented and developed. The chapter concludes with implications for understanding bullying as an important psychosocial hazard at work and recommendations for future research and practice across the Asia Pacific region
An Exploratory Investigation of the Risk of Pathogenic Contamination At Selected New Jersey Skilled Nursing and Assisted Living Residences
Elderly populations are vulnerable and generally have the highest incidence of morbidity related to foodborne illnesses and this problem may be aggravated in institutional or communal eating settings. The objective of this investigation was to examine the potential risk of food contamination in selected skilled nursing and assisted-living residences using bacteria indicator tests for Listeria spp., Salmonella spp. and E. coli. Of the 45 samples tested for Listeria, three (6.67 %) were found to be contaminated; Salmonella or E. coli contamination was not found in any of the samples. Reported incidents of foodborne illnesses are increasing in institutional settings, therefore there is an urgent need to collect information on practices that can prevent bacterial contamination of food served in elderly residences
