    135 leaves. Advisor: Herbert StrentzThere are journalists who would liken public journalism to the Phoenix that rose from the ashes of the failure of conventional journalism. Perhaps this observation is melodramatic, but public journalists often claim they have found the solution to save democracy. Yet these same people who claim that democracy is in decline and that traditional journalistic practices have significantly contributed to this decline may ignore that public journalism is a continuation of many beliefs, principles and theories that have shaped American journalism. Even the conditions that prompted the public journalism movement themselves are neither new nor unique. Throughout history public, governmental and even internal criticism of the media's performance can be found. Within that criticism can be found similar issues -public disinterest, government and elected officials attempting to control information, and journalists' failure to contribute to democracy. This thesis seeks to compare and contrast the journalistic philosophy of John Cowles Sr., a newspaper publisher whose career spans from the 1930s through the 1970s, within the current continuum of journalism, particularly focusing on public journalism. As the public journalism debate continues there is a need to examine what kind of journalism has been effective in the past instead of focusing primarily what is wrong. Concentrating on areas where journalism has worked before the advent of public journalism could provide examples of successful journalistic practices similar to what public journalists are promoting. In particular, this thesis finds the journalism practiced by John Cowles Sr. is a case study of the same "new" theory advocated by public journalists in the 1990s

AJBR is a Research Fellow of the Royal Commission for the Exhibition of 1851.We investigate the effect of the magnetic fields of M dwarf (dM) stars on potentially habitable Earth-like planets. These fields can reduce the size of planetary magnetospheres to such an extent that a significant fraction of the planet’s atmosphere may be exposed to erosion by the stellar wind. We used a sample of 15 active dM stars, for which surface magnetic-field maps were reconstructed, to determine the magnetic pressure at the planet orbit and hence the largest size of its magnetosphere, which would only be decreased by considering the stellar wind. Our method provides a fast means to assess which planets are most affected by the stellar magnetic field, which can be used as a first study to be followed by more sophisticated models. We show that hypothetical Earth-like planets with similar terrestrial magnetisation (~1 G) orbiting at the inner (outer) edge of the habitable zone of these stars would present magnetospheres that extend at most up to 6 (11.7) planetary radii. To be able to sustain an Earth-sized magnetosphere, with the exception of only a few cases, the terrestrial planet would either (1) need to orbit significantly farther out than the traditional limits of the habitable zone; or else, (2) if it were orbiting within the habitable zone, it would require at least a magnetic field ranging from a few G to up to a few thousand G. By assuming a magnetospheric size that is more appropriate for the young-Earth (3.4 Gyr ago), the required planetary magnetic fields are one order of magnitude weaker. However, in this case, the polar-cap area of the planet, which is unprotected from transport of particles to/from interplanetary space, is twice as large. At present, we do not know how small the smallest area of the planetary surface is that could be exposed and would still not affect the potential for formation and development of life in a planet. As the star becomes older and, therefore, its rotation rate and magnetic field reduce, the interplanetary magnetic pressure decreases and the magnetosphere of planets probably expands. Using an empirically derived rotation-activity/magnetism relation, we provide an analytical expression for estimating the shortest stellar rotation period for which an Earth-analogue in the habitable zone could sustain an Earth-sized magnetosphere. We find that the required rotation rate of the early- and mid-dM stars (with periods ≳37–202 days) is slower than the solar one, and even slower for the late-dM stars (≳63–263 days). Planets orbiting in the habitable zone of dM stars that rotate faster than this have smaller magnetospheric sizes than that of the Earth magnetosphere. Because many late-dM stars are fast rotators, conditions for terrestrial planets to harbour Earth-sized magnetospheres are more easily achieved for planets orbiting slowly rotating early- and mid-dM stars.Peer reviewe

    Lifestyle-Related Risk Factors and Risk of Future Nursing Home Admission

    While risks of disease, hospitalization, and death attributable to lifestyle-related factors such as smoking, inactivity, and obesity have been well studied, their associations with nursing home admission are less well known. These risk factors are usually established by middle age, but nothing is known about how they relate to long-term risk of nursing home admission in this age group. Cox proportional hazards regressions were used to analyze risk of nursing home admission over 2 decades of follow-up (1971-1975 to 1992) in a nationally representative, longitudinal survey of community-dwelling adults aged 45 to 74 years at baseline. Middle-aged (45-64 years at baseline) and elderly persons (aged 65-74 years at baseline) were analyzed separately: 230 (6.5%) of 3526 middle-aged respondents and 728 (24.7%) of 2936 elderly ones had 1 or more nursing home admissions. Baseline risk factors included smoking, inactivity, obesity, elevated blood pressure, elevated total cholesterol level, and diabetes mellitus, which were defined according to national guidelines. All lifestyle-related factors, except total cholesterol level, were associated with higher risk of nursing home admission during follow-up in one or both age groups. Risk ratios were higher in middle-aged than in elderly persons. In those aged 45 to 64 years at baseline, diabetes more than tripled the risk of nursing home admission (relative risk, 3.25; 95% confidence interval, 2.04-5.19); smoking, inactivity, and elevated systolic blood pressure had relative risks of 1.56, 1.40, and 1.35, respectively. Obesity was a risk factor for those aged 65 to 74 years at baseline, but not for the middle-aged subjects. Persons with 2 lifestyle-related factors were at greatly increased risk, especially if 1 was diabetes. Lifestyle factors are important contributors to the long-term risk of nursing home admission. Modifying lifestyle, especially in middle age, may reduce the risk of admission.Peer reviewe

    The frontal system of the Antarctic Circumpolar Current : marine mammals as ocean explorers

    No full text
    In this thesis, I describe large-scale and small-scale features of the Antarctic Circumpolar Current (ACC) by merging conductivity-temperature-depth (CTD) data obtained by novel animal-borne sensors with data obtained by more conventional means. Twenty-one CTD-Satellite Relay Data Loggers (CTD-SRDLs) were attached to Southern elephant seals (Mirounga leonina) on South Georgia in 2004 and 2005. This was part of a larger international study (Southern Elephant Seals as Oceanographic Samplers; SEaOS), in which I played a major role in developing the oceanographic approach used to integrate physical data from a range of sources, and the means to link biological findings to oceanographic parameters. The development of animal-borne oceanographic sensors and their potential place within an ocean observing system is reviewed initially. Then, I describe the Series 9000 CTD-SRDL in detail, discussing its performance in the lab and during two field experiences with Southern elephant seals and Weddell seals (Leptonychotes weddellii ). Following this, a detailed study of the ACC frontal system in the South Atlantic is presented that uses merged Argo float data and CTD-SRDL data. The structure of the frontal field revealed by this unique dataset is examined, and unprecedented insight into its variability is obtained. Amongst the important findings is that, contrary to most climate models, our in situ data suggest a northward shift of the ACC east of 40W in 2004 and 2005 compared to previous work. Next, two CTD-SRDL sections are presented to identify the locations of the ACC fronts across Drake Passage, and an empirical relationship between upper ocean temperature and baroclinic mass transport is used to determine the transport through Drake Passage at the times of the sections. This technique is a powerful complement to more conventional means of data collection in this region, especially given the ability of the seals to conduct "sections" at times when ship-based fieldwork is logistically most challenging, i.e. in the winter time. The CTD-SRDLs do not only record hydrographic data, but simultaneously record seal movements and diving behavior. This enables insight to be obtained on the behavioral and physiological responses of Southern elephant seals to spatial environmental variability throughout their circumpolar range. The resulting energetic consequences of these variations could help explain recently observed spatially varying population trends. With a stable population at South Georgia and declining populations at Kerguelen and Macquarie Island. This study also highlights the benefits to the sensorcarrying animals themselves by showing the usefulness of this approach in examining the sensitivity of top predators to global and regional-scale climate variability. More importantly, I conclude that, by implementing animal-borne sensors into ocean observing strategies, we not only gain information about global ocean circulation and enhance our understanding of climate and the corresponding heat and salt transports, but at the same time we increase our knowledge about ocean’s top predators, their life history and their sensitivity to climate change
