The Direction of Australian Investment from 1985/86 to 1988/89
Using unpublished data at a disaggregated level, this paper provides a detailed picture of the direction of investment over the 1985/86 to 1988/89 investment boom. Most of the growth in non-farm capital expenditure has been concentrated in a few industries, in particular, office construction. We also calculate an improved measure of the proportion of manufacturing investment which was directed towards tradeable capacity. This shows a modest rise in the latter part of the period studied.
Chronic Health Conditions as a Risk Factor for Falls among the Community-Dwelling US Older Adults: A Zero-Inflated Regression Modeling Approach
Falls are an important health concern among older adults due to age-related changes in the body. Having a medical history of chronic health condition may pose even higher risk of falling. Only few studies have assessed a number of chronic health conditions as risk factor for falls over a large nationally representative sample of US older adults. In this study, Behavioral Risk Factor Surveillance System (BRFSS) 2014 participants aged 65 years and older (n = 159,336) were evaluated. It was found that 29.7% (n = 44,550) of the sample experienced at least one fall and 16.3% (n = 20,444) experienced more than one fall in the past 12 months. According to the study findings, having a medical history of stroke, CKD, arthritis, depression, and diabetes independently predict the risk of first-time falling as well as the risk of recurrent falling in older adult population while controlling for other factors. On the other hand, having a medical history of the heart attack, angina, asthma, and COPD did not predict the risk of first-time falling, but did predict the risk of recurrent falling after experiencing the first fall in this population
Sudden death processing: an ethnographic study of emergency care
The following doctoral thesis provides an ethnographic account of sudden deathwork performed by emergency personnel. The study centres on three accident and emergency departments in the North East of England. Sudden death practices and perceptions are revealed using thick description from focus groups, narratives and informant accounts. Three emergency disciplines: accident and emergency nurses, police traffic officers and paramedics provide the backdrop to describing three sudden death trajectories, which take the dead body from a state of collapse to a mortuary. Particular attention is paid to the significance of status passage as a temporal dimension of deathwork with due consideration being given to the concept of body handling as 'dirty work'. A feminist concept of embodiment challenges the dominant discourse of the death processing industry in relation to beneficence and non- maleficence for those who are left behind to grieve. The theatrical representation of the body to relatives is discussed within a dramaturgical frame, questioning what is appropriate and achievable within the boundaries of an emergency care environment. An exploration of the roles of emergency personnel illuminates problems of dealing with a phenomenon, which annihilates the possibility of a sense of order and emotionally incapacitates emergency personnel. The procedural base to sudden death is presented through accounts of emergency personnel contact with human suffering and emotional pain with the intention to build a substantive theory of a sudden death milieu. Finally, Schutzian relevances highlight key concepts of significance within the data demonstrating how, despite an evidence-base to practice, some myths are highly influential in shaping the behaviours of emergency personnel throughout the sudden death event. It is hoped that insight gained may provide a catalyst to inform change where needed, in service provision and enhance interprofessional working relationships
A PROSTAGLANDIN SYNTHASE INHIBITION ASSAY WITH DETECTION BY ELISA
A simple, reliable method is described for the routine measurement of non-steroidal anti-inflammatory drugs (NSAIDs) as inhibitors of prostaglandin synthase. Appropriate concentrations of inhibitor are incubated with ram seminal vesical prostaglandin synthase, sodium arachidonate and reduced glutathione. Prostaglandin E2 (PGE2) production is then quantitated by and enzyme linked immunosorbant assay (ELISA), in which anti-PGE2 antibody is utilized in a binding competition between test sample and adsorbed conjugate of PGE2-BSA. The antibody which remains bound to the solid phase is quantitatively determined colorimetrically by incubation with horse radish peroxidase labeled goat anti-rabbit IgG followed by incubation ·with N,N,N\u27,N\u27,-tetramethylbenzidine.
The relative inhibitory potency of Indomethacin was determined by comparison of PGE2 content in sample incubations, with that of controls containing no Indomethacin and was shown to inhibit prostaglandin synthase.
The combination of enzyme-inhibitor incubation assay with detection by ELISA permits the testing of other NSAID compounds for their ability to inhibit prostaglandin synthase activity expediently, and in a financially feasible manner. Furthermore, the use of an ELISA system eliminates radioactive and toxic chemical waste genera ted by radioimmu no assay methods
The new age of customer impatience: An agenda for reawakening logistics customer service research
Purpose The purpose of this paper is to shed light on the body of logistics customer service (LCS) research published in leading logistics journals from 1990 to 2017. Specifically, the paper presents a call to arms for logistics and supply chain researchers to address new and emerging issues impacting customer service in the age of omnichannel and e-commerce retailing.
Design/methodology/approach The authors reviewed academic journals to identify articles focusing on LCS from 1990 through 2017. The authors noted trends in academic research activity/focus and supplemented the findings by examining more recent trends covered in trade publication articles.
Findings The authors observed a large amount of LCS research in the early 1990s and 2000s, but noticed a substantial decline in coverage within academic journals since the late 2000s while industry continues to give customer service issues even greater attention. The difference between the level of coverage within academic journals and the increased importance firms place on customer service represents a critical gap and opportunity for scholars. This research represents a “call to arms” to address this gap. With particular emphasis on observed customer impatience and escalating requests, within omni- and e-commerce channels of distribution, we suggest greater theoretical insights into customer service strategies and their role in successfully navigating today’s changing logistics service environment are needed.
Originality/value The review serves as a call for more attention to customer service issues within leading logistics journals. Suggestions for research into new and emerging topics are offered
A study of the saturation characteristics of ionization chambers
The aim of this thesis was to make a combined theoretical
and experimental investigation into the saturation characteristics
of two types of parallel plate ionization chambers - the free -air
chamber and the extrapolation chamber.Despite the great importance of free -air chambers in
standardising laboratories, little theoretical consideration seems
to have been given to their saturation losses. The theories
surveyed in 1.2 deal with uniform ionization in a parallel gap and
are not directly applicable to a free -air chamber where the X -ray
beam often occupies a small proportion of the collecting volume.
Hubner (1958) appears to be the first to calculate the
recombination occurring in a free -air chamber. He modified
the equation of Von Engel and Steenbeck to take into account the
fact that the ionization did not fill the space between the
electrodes. He claimed that correction factors calculated from
his formula agreed within 0.3 per cent with factors determined
experimentally at the National Bureau of Standards. We found
that these experimental results covered only a limited range of
conditions and as they concerned corrections usually less than
1 per cent, hardly constituted an accurate check of the theory.We felt that Hi.bner °s treatment could be improved upon by a different choice of recombination formula. Although Shevyrev's
work pointed to Mies equation, we decided to use the derivation
due to Boag and Wilson which was in a more convenient form for
the further modifications we intended to carry out. By
considering the effects of space charge and ion diffusion on the
basic recombination equation, we sought to derive an expression for
the saturation losses in a free -air chamber. We then planned to
check our theory by experiments using a free -air chamber (Greening,
1960) over a wide range of operating conditions.It was foreseen that it would be a formidable task to set up a theory governing saturation losses in an extrapolation chamber.
Loevinger (1953) quoted an empirical relation for f as a function
of (1/√Vd) obtained from experiments with ß-ray sources for plate
spacings in the range 0.01 to 0.2 cm. and ionization intensities up
to 25 e.s.u. /cm.³sec. This function for f is at variance
with all previously described theories. We would expect the
situation in an extrapolation chamber to be an extremely complex one
since the use of very small air gaps and low ß-intensities is likely
to result in losses from diffusion and initial recombination
superimposed on volume recombination losses. Loevinger's result
does, however, seem surprising since all theories describing these
types of losses contain V to the power 1 if not higher.It seemed worth-while, therefore, to design and construct a simple extrapolation chamber and make an intensive study of the
variation of ionization current with the various parameters involved.
We planned to discuss the theoretical significance of these
experimental results, making quantitative evaluations where possible
The enrichment of the teaching of English through correlation with fine arts
Thesis (Ed.M.)--Boston UniversityThe purpose of this thesis is to enrich the
study of English by constructing a resource unit which will
illustrate to high-school students the interrelation of literature
and fine arts. This unit, entitled "Picture of Man,"
correlates the study of works of literature and of fine art
which express similar concepts of the nature of man and. which
represent similar techniques
Reality and continuity: Peirce and James
Thesis (M.A.)--Boston UniversityThe purpose of this thesis is to compare and contrast the thought of Charles Sanders Peirce and William James in two respects: (1) their ideas of reality and (2) their doctrines of the continuity of consciousness and its metaphysical implications.
Chapter II traces their different theories of reality to basic differences in their metaphysical orientations. Peirce, as a metaphysical realist, maintains that general terms refer to ideas and laws which are realities apart from the particulars which manifest them and the minds which apprehend them. The real correspondents of general terms are within two realms of being: the realm of first-ness, which is possibility and feeling; and the realm of thirdness, which is law, meaning, and thought, all of which are synonymous. Both differ from the world of existence, or secondness, in which possibility is actualized, and in which ideas, including laws, are physically and mentally operative. [TRUNCATED
Continuity And Change In The Wiseman Area Of Alaska: A Look At Land And Renewable Resource Use Over Time
Thesis (M.S.) University of Alaska Fairbanks, 1993Land and renewable resource use by residents of the Wiseman area in the central Brooks Range of Alaska was investigated in 1991-1993. The study documents current and historic land and renewable resource use patterns of local residents, records resident and agency management concerns regarding these uses, and analyzes opportunities and constraints that exist for rural Alaskan communities in utilizing renewable resources. The research was accomplished through resident interviews, participant observation of community activities, and review of other community studies. Conclusions include: (1) the Wiseman community exhibits characteristics of a mixed subsistence/cash economy; (2) residents rely on resources harvested in the various local federal, state, and private land management units; and (3) the establishment of the nearby National Park, and the construction of the Dalton Highway, have significantly affected local resource use. The study also demonstrates how community involvement in research effectively allows comprehensive documentation of land and resource use. <p
