The Independent Newspapers Limited study: an investigation into occupational overuse syndrome within the newspaper industry : a thesis presented in partial fulfilment of the requirements for the degree of Master of Arts in Psychology at Massey University
An investigation was undertaken into occupational overuse injuries. Overuse injuries are commonly associated with repetitive movements, sustained or constrained postures, and forceful movements. Other factors, such as work environment, amount of keyboard use, and the ergonomic status of the work area, have been identified as elements in the development of overuse injuries. These perspectives were used to provide research objectives in studying a sample of subjects working in the newspaper industry. Five hundred and seventy five respondents completed a questionnaire, which included a measure of the incidence and severity of overuse injuries, and questions aimed at discovering the effectiveness of different types of treatment and intervention strategies. Using a combination of descriptive and bivariate statistics, this data was analyzed. The analysis revealed low levels of reported muscular aches and pains. Of those subjects who did report some form of ache or pain, the majority answered that the level of their aches and pains had remained the same. As well, the image of the aetiology of overuse injuries which emerged, was in contradiction to much of the proceeding research in this area. The analysis also demonstrated that the treatment and intervention strategies being employed were ineffective. This was despite the fact that subjects often reported that they considered a particular strategy to be productive in managing their overuse injury. In the discussion section, the limitations of the questionnaire as a survey technique in this area of research was considered, and the possible effects these limitations have on the present study. This point has special relevance to the application of clinical models of overuse injury. It was concluded that the results demonstrated a need for research into effectively manipulating working conditions to counter-act the development, incidence and severity of overuse injuries. Such strategies as job enlargement and job rotation were suggested

Relationships between Stock Prices and Accounting Information: A Review of the Residual Income and Ohlson Models
As one of the main purposes of financial statements is to provide relevant information for investors, relationships between share prices and accounting variables have been widely researched. Early studies focus mainly on earnings, but attention has turned in recent years to valuation models that include the book value of the equity. Many of these studies cite the residual income model as their theoretical base and, with the growing emphasis on shareholder value, residual income measures are more commonly used in the business community to track financial performance. Given such trends, this paper reviews the theoretical background of the residual income model and discusses results of empirical studies that use it. The study finds that the two main accounting variables can usually explain a substantial part of the variation in share prices, and it also identifies a number of issues that remain unresolved. These findings should be of interest to other researchers, and to managers and investors who currently use or are planning to use residual income to monitor business performance.
California coastal processes study, LANDSAT 2
The authors have identified the following significant results. By using suspended sediments as tracers, objectives were met by qualitative definition of the nearshore circulation along the entire coast of California with special study sites at Humboldt Bay, the mouth of the Russian River, San Francisco Bay, Monterey Bay, and the Santa Barbara Channel. Although LANDSAT primarily imaged fines and silts in the surface waters, the distribution of sediments allowed an examination of upwelling, convergences and coastal erosion and deposition. In Monterey Bay and Humboldt Bay, these coastal phenomena were used to trace seasonal trends in surface currents
California coast nearshore processes study
The author has identified the following significant results. Large scale sediment plumes from intermittent streams and rivers form detectable seasonal patterns on ERTS-1 imagery. The ocean current systems, as plotted from three California coast ERTS mosaics, were identified. Offshore patterns of sediment in areas such as the Santa Barbara Channel are traceable. These patterns extend offshore to heretofore unanticipated ranges as shown on the ERTS-1 imagery. Flying spot scanner enhancements of NASA tapes resulted in details of subtle and often invisible (to the eye) nearshore features. The suspended sediments off San Francisco and in Monterey Bay are emphasized in detail. These are areas of extremely changeable offshore sediment transport patterns. Computer generated contouring of radiance levels resulted in maps that can be used in determining surface and nearsurface suspended sediment distribution. Tentative calibrations of ERTS-1 spectral brightness against sediment load have been made using shipboard measurements. Information from the combined enhancement and interpretation techniques is applicable to operational coastal engineering programs
California coastal processes study: Skylab
The author has identified the following significant results. In San Pablo Bay, the patterns of dredged sediment discharges were plotted over a three month period. It was found that lithogenous particles, kept in suspension by the fresh water from the Sacramento-San Joaquin, were transported downstream to the estuarine area at varying rates depending on the river discharge level. Skylab collected California coastal imagery at limited times and not at constant intervals. Resolution, however, helped compensate for lack of coverage. Increased spatial and spectral resolution provided details not possible utilizing Landsat imagery. The S-192 data was reformatted; band by band image density stretching was utilized to enhance sediment discharge patterns entrainment, boundaries, and eddys. The 26 January 1974 Skylab 4 imagery of San Francisco Bay was taken during an exceptionally high fresh water and suspended sediment discharge period. A three pronged surface sediment pattern was visible where the Sacramento-San Joaquin Rivers entered San Pablo Bay through Carquinez Strait
