State Sentencing Guidelines: Profiles and Continuum
Describes twenty-one state sentencing commissions; highlights key attributes of each state's sentencing guidelines and the composition of each commission; and compares guideline systems along a continuum from "more voluntary" to "more mandatory.
Fragmentation of Agricultural Land Parcels
This study seeks to take fragmentation research in a new direction by looking at exurban sprawl and fragmentation of ownership. The primary objective of this study is to identify the location and magnitude of fragmentation of agricultural land parcels sold in Oklahoma. This was accomplished by estimating two different models. The first model regressed a polynomial in time to determine whether or not fragmentation has been increasing over time. While it was hypothesized that parcel size was decreasing, this was not found to be the case. Over the 40 years of data, parcel size was found to only have decreased by one acre. The purpose of the second model was to verify whether or not a location premium exists for small parcels. It was found that a location premium does exist for smaller parcels with parcels in urban counties more likely to receive a premium than those located in more rural counties.fragmentation, land values, parcel size, Production Economics,

Long-term changes in the water quality of rainfall, cloud water and stream water for moorland, forested and clear-felled catchments at Plynlimon, mid-Wales
Long term changes in the water quality of rainfall, cloud water and stream waters draining acidic and acid sensitive moorland and forested catchments at Plynlimon, mid-Wales, are examined for the period 1983 to 2001. Atmospheric inputs of chloride and sulphate are influenced by the relative inputs of clean maritime and polluted land based air masses. There is no systematic increase or decrease over time for chloride and non-sea-salt sulphate. Rather, there is a decadal scale process possibly representative of the influence of the North Atlantic Oscillation that affects the maritime and pollution climate of the Atlantic seaboard of the UK. Over 17 years of study, there may be a small decrease in non-sea-salt sulphate of about 10 μeq l<sup>-1</sup> and a small improvement in acid neutralising capacity of about 20 to 30 μeq l<sup>-1</sup> in rainfall. There is a clear improvement in cloud water chemistry with respect to pollutant components (ammonium, nitrate, non-sea-salt sulphate) and acidity (acid neutralising capacity improved by about 300 μeq l<sup>-1</sup>) through the study period. Many of the changes in cloud water chemistry are similar to rainfall over the same period except the magnitude of change is larger for the cloud water. Within the streams, there is some evidence for reductions in acidity as reflected by acid neutralising capacity becoming less negative. For one stream, deforestation occurred during the sampling period and this led to large increases in nitrate and smaller increases in aluminium midway through the study period. However, the climate and hydrological variability largely masked out other changes. The current analysis provides only a start to identifying trends for such a complex and variable environmental system. The need for strong statistical tools is emphasised to resolve issues of: (a) hydrological induced water quality variability, (b) changing soil and groundwater "endmember" chemistry contribution to the stream and (c) the non-linear patterns of change. Nonetheless, the analysis is enhanced by examining trends in chemistry for yearly averages and yearly average low catch and high catch rainfall and cloud water events as well as low and high flow stream chemistry. This approach allows trends to be examined within the context of endmember mixing.</p> <p style='line-height: 20px;'><b>Keywords: </b>Calcium, aluminium, ammonium, pH, Gran alkalinity, ANC, nitrate, chloride, sulphate, Plynlimon, cloud, mist, rainfall, stream, acidification, North Atlantic Oscillation, trend
The effects of massage therapy on delayed-onset muscle soreness after unaccustomed exercise for healthy, sedentary adults
This study examined the effects of massage therapy on delayed-onset muscle soreness (DOMS) following unaccustomed exercise in healthy, sedentary adults. Fifteen volunteers between the ages of 23 and 63 performed 100 calf raises followed by 15 minutes of rest. After the rest period, one leg was randomly assigned to receive a 5-minute massage while the other leg received a 5-minute placebo ultrasound treatment. A questionnaire was administered to evaluate DOMS at 24, 48, and 72 hour posttreatment intervals when DOMS reportedly is at its peak. A double blind control was employed so that the examiner was unaware as to which treatments were performed on each leg. A t-test for nonindependent samples was used with significance set at the 0.05 level. There was less DOMS reported in the massaged leg at each interval, however, only a significant reduction in DOMS was reported at the 24 hour posttreatment interval
Langmuir-Blodgett films for non-linear optics
In recent years there has been considerable interest in media which display significant non-linear optical properties; the telecommunications industry may exploit chin films of such materials for signal processing applications. The Langmuir-Blodgett (LB) technique provides a means of depositing organic layers of a precisely defined thickness. Moreover, by alternating layers of different materials, supermolecular arrays may be fabricated in which there is no centrosymmetry, and therefore the second-order non-linearity of the constituent molecules may be exploited. An investigation of the properties of water-surface monolayers of a number of novel materials with potentially large non-linearities is described. Several of these compounds are shown to form high quality homogeneous or heterogeneous LB films. The optical and electrical properties of the layers are characterized by optical absorption spectroscopy, surface plasmon resonance, and measurements of capacitance, whilst their structure is examined by electron diffraction. Monolayers of a nitrostilbene dye are shown to exhibit: on exceptionally high degree of crystalline order. Data are also given for theoretical calculations of non-linear coefficients and for the relative efficiency of second harmonic generation from bulk samples of various materials. Studies of second harmonic generation from monolayer and alternate multilayer films are reported. Optical non-linearity in an alternating donor-acceptor: inverted donor-acceptor dye system is demonstrated for the first time; the results are analysed in terms of second harmonic surface susceptibilities, and the value of the second-order hyperpolarizability determined for the first bilayer is found to be much superior to that expected by the simple addition of the hyperpolarizabilities of the separate layers. Monolayers containing a mixture of hemicyanine and cadmium arachldate are found to give rise to second harmonic generation which is enhanced relative to that obtained from a pure monolayer of the dye. Corresponding changes in the absorption spectra of the layers can be observed. These findings may have important implications for improving the efficiencies of any non-linear optical device which utilises IB films
