The caring commodity : transformations in the exchange character of medicine in New Zealand (1840-1985) : a thesis presented to the Dept. of Geography, Massey University in complete fulfilment of the requirements for the degree of Master of Arts
Retrospective analysis of actions and interactions connected with health care makes evident their place as constituted and constitutive components of capitalist social relations. The contextually constrained activity of individuals to achieve certain ends has contributed to the production of outcomes which appear to be beyond individual control and which shape the social world. In explaining the main transformations in the character of medical services since the early days of European settlement emphasis is placed upon the multiple and differentiated emergence of various structures of relationships between, principally, doctors and patients, doctors and doctors, and those who, at various stages, have attempted to intervene in those relations.
Over the period 1840-1985, medical practice has been transformed from a service provided on a user-pays basis, to one of collective provision, and back towards the "private" sector. In the six decades after 1840 medicine and the State became enmeshed. Some moves towards the State provision of health care services occurred. The period 1900-35 saw the supporters of both free enterprise and socialistic medicine inexorably drawn towards advocacy of some grand scheme of collective care, the character of which was extensively debated from 1935 until 1942. The outcome brought "free" provision of most medical care to those in need and also served the long term interests of capital. Since then, health care has been returning to the market. In part, the broad sweep from, and back to, commodity relations has arisen from actions to "solve" problems of health care provision and use. The solutions arrived at, however, have been compromises between conflicting demands. Although at times "solutions" may have facilitated the more humane allocation of medical services, the general tendency is for them to reproduce capitalist social relations
Unsafe Act as the Risk Factors of Accidents in Using Mill in Roof Tile Industry at Pejaten Village Tabanan Regency
The use of mill and hand press machines had been increased the productivity ofroof tile home industry at Pejaten Village Tabanan Regency. But the increased ofproductivity followed by increased of working accidents. Many effort had been done toreduced the accident such as equipped the mill machine with machine's cover, footprotective devices, and training to the new employees; but, the accident still happen.Although the incident of accident was lower but the disability was severed such as loss ofhand, loss oh finger, or other physical defects of the body part. Such physical defectscaused a serious effect on worker's daily lives and social activities. To find out the unsafeacts as the risk factors of accident, a retrospective study was done using interview and onthe spot observation to the milling process. The results are found: there are three riskfactors contributed to the accidents, namely: the human factor, the tools and theenvironment. The human factor contributed highest one for the accident. From humanfactors it was found that there are many unsafe acts, such as: careless, going up to theupper inlet of mill to push mixing raw material with foot or hand, moving the millwithout turn off the machine, cleaning the mill without turn off the mill, taking out thestone which trapped the rollers using hand, operating the machine without guarding,working with tired condition, working without knowing the operation procedure, withouttraining, improver lighting, working without personal protective devices, etc. The highestincidents come from pushing the raw materials on inlet of mill in order to speed-up themilling process. To solve the problems some actions must be done such as providing themill with the appropriate equipments; by doing so, the operator can push the materialsafely to speed-up the mill process, turn off the machine before cleaning, appropriatetraining before operating of mill, using the personal protective devices, and doing goodhouse keeping and inspection, regularly
Method and tool for machining a transverse slot about a bore
A method and apparatus for cutting a transverse slot about a bore of smaller diameter than that of the slot are disclosed. The invention consists of introducing a cutting head facing transversely to the bore, through the bore opening its distance from the mill shaft being progressively extended by the addition of spacers between the head and the shaft until the desired slot depth is obtained. The spacers are held in position by a cable passing from the cutting head through the series of spacers and out along the mill shaft. The mill shaft carrying the cutting head is moved transversely into the object wherein the slot is being cut as the object is being rotated thereabout by the mill table to which it is affixed
Gas leakage and distribution characteristics of methyl bromide and sulfuryl fluoride during fumigations in a pilot flour mill
The half-loss time (HLT) is used as an indicator to quantify gas leakage rates during methyl bromide (MB) and sulfuryl fluoride (SF) fumigations. Comparisons of HLTs between three MB and three SF fumigations were quantified in the Hal Ross pilot flour mill, Department of Grain Science and Industry, Kansas State University, USA. The sealing quality or gas tightness of the mill before each fumigation was verified by a pressurization test. Fumigant concentrations during the six fumigations were monitored continuously at 30 locations among the five mill floors during the 24 h fumigation period. A weather station on the mill roof monitored barometric pressure, wind speed and direction, temperature, and relative humidity. A data logger on each mill floor recorded temperature and relative humidity. The pressurization test showed that the relationship between airflow rate and building static pressure varied among the fumigations despite the same areas being sealed by two separate fumigation service providers due to environmental conditions not being identical among the fumigations. Concentrations of both fumigants within the mill ranged from 2 to 7 g/m³ . The observed HLTs for the MB and SF fumigations were in the range of 3.61 to 28.64 h and 9.97 to 31.65 h, respectively, and were inversely related only to wind speeds during fumigation and not any other environmental conditions recorded. In our study, the fumigant leakage rate was found to be predominantly a function of wind speed rather than inherent gas characteristics of MB and SF
LOX/GOX sensitivity of fluoroelastomers
The effect of formulation components and the addition of fire retardants on the impact sensitivity of Viton B fluoroelastomer in liquid oxygen was studied with the objective of developing a procedure for reliably reducing this sensitivity. Component evaluation, carried out on more than 40 combinations of components and cure cycles, showed that almost all the standard formulation agents, including carbon, MgO, Diak-3, and PbO2, will sensitize the Viton stock either singly or in combinations, some combinations being much more sensitive than others. Cure and postcure treatments usually reduced the sensitivity of a given formulation, often dramatically, but no formulated Viton was as insensitive as the pure Viton B stock. Coating formulated Viton with a thin layer of pure Viton gave some indication of reduced sensitivity, but additional tests are needed. It is concluded that sensitivity in formulated Viton arises from a variety of sources, some physical and some chemical in origin. Elemental analyses for all the formulated Vitons are reported as are the results of a literature search on the subject of LOX impact sensitivity
Modelling the impacts of mechanized surgarcane harvest on noodsberg supply chain : Visit report to University of KwaZulu-Natal, 26 April - 4 May 2007
This visit to the University of KwaZulu-Natal was part of the joint CIRAD - UKZN PROTEA project focused on Integrated supply chain modelling applied to sugar cane. It was aimed at supervising the French student who works on the Noodsberg mill area in order to assess the impacts of mechanized harvesting on its supply chain. Two growers harvesting their cane mechanically were interviewed, as well as the mill procurement officer and the Sasri extension officer based in this area. A visit to the mill yard allowed understanding the cane off load systems in place and the various constraints linked to that part of the chain. Three mechanical harvest logistic chains were described based on these interviews and field observations. Discussions were led to conceptualize the logistic chain modelling and to design N scenarios based on various mechanized harvest ratios and kind of cane (green vs burnt). These scenarios will be simulated using jointly the ARENA and MAGI software. The harvester/lorries fleet size required to deliver a given amount of cane within a specific LOMS (Length of Milling Season) will be assessed, as well as the scenarios' impact on the sugar production of the mill area.
