Agricultural aviation research

A compilation of papers, comments, and results is provided during a workshop session. The purpose of the workshop was to review and evaluate the current state of the art of agricultural aviation, to identify and rank potentially productive short and long range research and development areas, and to strengthen communications between research scientists and engineers involved in agricultural research. Approximately 71 individuals actively engaged in agricultural aviation research were invited to participate in the workshop. These were persons familiar with problems related to agricultural aviation and processing expertise which are of value for identifying and proposing beneficial research

Community attitudes and the role of the victim offender relationship in child sexual abuse cases

Past research has illustrated that communily attitudes tend not to be reflected in crime legislation particularly when considering the victim-offender relationship and perceived seriousness of child sexual abuse. This study examined the effects of 4 different victimoffender relationships and the degree of trust within these relationships on perceptions of offence seriousness and emotional and physical harm, for the offence of indecently dealing with a 14-year old girl. One hundred and sixty community members used a 7- point scale to rate the degree of trust within these relationships, the seriousness of the offence and the emotional and physical harm suffered by the victim. Four two-way ANOVAs and one correlation were perfonned. Results showed that the victim-offender relationship failed to influence perceptions of offence seriousness, emotional and physical harm. Although the ratings of trust differed across the 4 relationship types, trust failed to significantly influence perceptions of offence seriousness, emotional and physical harm. Women were found to rate the offence as more serious and harmful than men. Possible explanations for these findings are discussed

Improving Handicappers\u27 Civil Rights in Michigan--Preventing Discrimination Through Accommodation

Part I of this Note explains the development of· the current state of handicappers\u27 civil rights law in Michigan, beginning with legislative initiatives and progressing to administrative and judicial decisions. Part II analyzes traditional antidiscrimination theory and suggests how that theory can be adapted to handicappers. By examining hypothetical situations, Part III exposes the disparity between the current state of the law in Michigan and the proposed theoretical analysis and suggests amendments to the MHCRA to reconcile this disparity

Family Knowledge of Postsecondary Costs And Financial Aid

Federal policymakers have recently expressed interest in family knowledge of student financial aid and postsecondary costs and the impact of family knowledge on student access. Analyzing a longitudinal data set of Indiana high school students, this study looks at student and parental knowledge of student financial aid and postsecondary costs. The results suggest that parents are more interested than students in information about postsecondary costs and student financial aid. Furthermore, the findings indicate that efforts to increase family knowledge should simultaneously focus on general information about aid and costs rather than on details about specific aid programs. This article was presented at the Seventh Annual Meeting of the Student Financial Aid Research Network Conference, Washington, D. C., May 16, 1990

Presidential Satisfaction with Development Programs in Research and Doctoral Universities

The increasing costs of higher education and the decreasing willingness of taxpayers to support it have amplified the importance of fundraising in the modern university. The (dis)satisfaction of the university president with his/her development program can have profound ramifications for the success of the program and the careers of the development professionals. This paper addresses a gaping hole in the academic and practitioner knowledge base: What makes presidents satisfied and/or dissatisfied with their institution’s development efforts and how do they evaluate the performance of the development program

Investigation of Transfer Function Analysis as a Means to Predict Strain on Rat Tibiae from Ankle Torque Waveforms

Electrical Muscle Stimulation (EMS) is used as a countermeasure in animal disuse studies that seek to determine which forms of exercise are most effective in mitigating the effects of disuse atrophy on bone and muscle. Although EMS has been used for many years in our lab and others, few researchers have been able to quantify the levels of strain on rat tibiae during EMS and far fewer have investigated the causal relationship between torque produced at the ankle and strain on the tibia. This thesis sought to investigate the relationship between ankle torque and tibial strain by using a combination of techniques, namely: (1) the addition of rosette strain gages, (2) improved synchronization between ankle torque and tibial strain recordings, and (3) spectral analysis between torque and strain waveforms. In previous work, few methods existed to align torque and strain recordings temporally, as those data were recorded on separate computers and synchronizing events were not captured. Attempting to create a torque-strain crossplot with unsynchronized data does not always yield valid results, so a method of reliably synchronizing those data is required. This thesis developed methods to capture simultaneous (synchronizing) events in both torque and strain recordings and then used those captured events to synchronize data between two computers. Following that synchronization, stiffness calculations were run on torque-strain crossplots to determine linear-model relationships between torque and strain for each method of synchronization. The results from those regressions were then used to determine if one or more synchronization techniques are superior to others, in terms of repeatability or precision. The results of these analyses have shown that using portions of the curves can dramatically increase computing speed while providing high levels of repeatability in synchronization measures. After synchronization techniques had been investigated, 3-element rosette data were used to calculate the principal strains on the surface of the tibiae, and the percentage of principal strains that are accounted for in the axial direction. Since the strain environment changes along the axis of the bone, the principal strain data were plotted versus the distance from proximal epiphysis to rosette gage, and statistical analysis was presented. After rosette data were analyzed, the torque and strain data pairs were fed into a signal processing suite for the purpose of transfer function calculation. Using the synchronization methods outlined above, two means of synchronization were compared in the transfer function program. Results for these analyses demonstrated that transfer functions are slightly dependent on synchronization methods, but that calculated gains do not differ between synchronization techniques. The specific shapes of the transfer functions highlight the relative attenuation/amplification of frequencies in torque and strain signals. Specifically, a range of frequencies, commonly called a band, between 24 and 32Hz is attenuated by the soft tissues and mechanical linkages in the lower leg of rats. This finding gives researchers looking to increase or decrease modeling stimulus to bone a new piece of information about the relative efficiency of EMS exercise. For example, EMS performed at 24-25Hz might produce less strain in the tibia than EMS at 22-23Hz, despite the 22-23Hz stimulation producing marginally less torque
