CRISIS TO OPPORTUNITY TO CHANGE
As diverse groups (from tenured professors to their unbenefited colleagues; Palestinian intifadists to Zionist real estate developers; native Europeans to crisis driven refugees; entrenched leaders in their ?Arab Winters? to fellow countrymen in their discordant ?Arab Springs?) struggle to gain possession of lost, stolen, or disputed pieces of soil or self, our world finds itself enmeshed in ever deepening levels of conflict. Diverse groups collide in a battle to attain the prizes of territory, identity, security, and respect. As battle lines are drawn, friction becomes evident and conflict becomes endemic.These are the conflicts that know no boundaries. They release their tremors into Everyman?s village and their traumas into Everyman?s soul. Like swollen streams, they flow down trash-laden streets and onto tree-lined boulevards. They move from sectors of third world tragedy through centers of new world trade; through the halls of fortified high schools and over the walls of sanctified universities; into pristine rural communities and through sectarian tribal villages; through distressed urban war zones and into sheltered enclaves of wealth.These are the conflicts that ignore the rules of scholarly discourse. They are filled with all the invective and passion that diverse groups, struggling for their social, intellectual, and/or physical lives tend to manifest. To some they are threatening. To others they are encouraging. To all they are stimulating.They capture attention; they capture imagination; and they capture resources?Triggers for these conflicts seem to exist most everywhere... a political slight; a perceived inequity; a change in the balance of power; a long-standing hurt; today?s exploitation; yesterday?s grudge.Along with a diversity of triggers comes a diversity of targets...Corporations with unimaginable wealth... Nations with unimaginable power... Well-established political bodies? Newly-established political movements? Universities? A religiously sectarian community? None are beyond scrutiny. None are beyond threat.The author/presenter explores how conflict can provide individuals, institutions and political states with precious opportunities to recognize and institute procedures that can lead toward creating personal, social and political change. A model designed to effectively process conflict and facilitate essential change, the seven stage Crisis to Opportunity to Change is presented.

The inclusive polarized structure functions of the proton and deuteron, g1p and g1d, were measured with high statistical precision using polarized 6 GeV electrons incident on a polarized ammonia target in Hall B at Jefferson Laboratory. Electrons scattered at lab angles between 18 and 45 degrees were detected using the CEBAF Large Acceptance Spectrometer (CLAS). For the usual DIS kinematics, Q^2>1 GeV^2 and the final-state invariant mass W>2 GeV, the ratio of polarized to unpolarized structure functions g1/F1 is found to be nearly independent of Q^2 at fixed x. Significant resonant structure is apparent at values of W up to 2.3 GeV. In the framework of perturbative QCD, the high-W results can be used to better constrain the polarization of quarks and gluons in the nucleon, as well as high-twist contributions.
Read moreWhat’s Ahead in Faculty Collective Bargaining? The New and the Déjà Vu
As faculty collective bargaining reaches the half-century mark, the authors take a critical look at what has or has not worked at the bargaining table; how the early expectations of what faculty bargaining would bring to the academy have or have not been realized; and what the future holds, both in terms of process and the substantive issues that will be brought to the table. Dr. Julius has been a faculty member, administrator and employer representative in negotiations at many institutions; Mr. DiGiovanni has served a labor counsel and has negotiated with faculty unions at numerous institutions since the late 1970s. Both share their retrospective on what is new today and what has not changed over that time.
Read moreHistorical fire and bamboo dynamics in western Amazonia
Abstract AimTo determine if recurrent fire accounts for bamboo‐dominated forests that cover about 180,000 km2 of western Amazonia.LocationWestern Amazonia, including Los Amigos and Cocha Cashu, Peru, and Acre, Brazil.MethodsWe identified bamboo (B+) and closed‐canopy forests (B−) using a combination of MODIS imagery, Landsat TM imagery and field surveys. Local‐scale and landscape‐scale patterns of historical bamboo dynamics were analysed by collecting soil cores from B+ and B− sites across three regions. Soil charcoal within cores was used to document previous fire, and phytoliths were employed to reconstruct vegetational patterns through time.ResultsFire occurred in B+ and B− sites with approximately equal frequencies in each region sampled. Between regions, fire signals were most prevalent at Los Amigos, with Cocha Cashu and Acre sites typically containing only trace amounts of charcoal. Vegetational state remained constant through time in both B+ and B− forests of Cocha Cashu and Acre. The persistence of bamboo through time is less clear at Los Amigos, with bamboo presence changing both spatially and temporally.Main conclusionsFire does not appear to be the driving mechanism behind current bamboo distributions, although it may facilitate bamboo invasion. Once established in an area, bamboo persistently dominates the vegetation structure over historical time‐scales at some sites (Cocha Cashu and Acre), but not at others (Los Amigos), which is likely to be a function of patch origin. Increasing human activity, including fire and deforestation, combined with predicted Amazonian drought, may allow bamboo to expand from its current distribution and replace typical Amazonian closed‐canopy forests. These structural changes in the forests have important implications for carbon storage, as Amazonian forests are currently the largest terrestrial carbon sink in the world.
Read morePhysical interpretation of the correlation between multi‐angle spectral data and canopy height
Recent empirical studies have shown that multi‐angle spectral data can be useful for predicting canopy height, but the physical reason for this correlation was not understood. We follow the concept of canopy spectral invariants, specifically escape probability, to gain insight into the observed correlation. Airborne Multi‐Angle Imaging Spectrometer (AirMISR) and airborne Laser Vegetation Imaging Sensor (LVIS) data acquired during a NASA Terrestrial Ecology Program aircraft campaign underlie our analysis. Two multivariate linear regression models were developed to estimate LVIS height measures from 28 AirMISR multi‐angle spectral reflectances and from the spectrally invariant escape probability at 7 AirMISR view angles. Both models achieved nearly the same accuracy, suggesting that canopy spectral invariant theory can explain the observed correlation. We hypothesize that the escape probability is sensitive to the aspect ratio (crown diameter to crown height). The multi‐angle spectral data alone therefore may not provide enough information to retrieve canopy height globally.
Read moreUsing Publications Counts to Measure an Institution's Research Productivity
Studies that attempt to evaluate and rank institutions often overlook the research activities of an institution. In this article, we show how readily available data from the Institute of Scientific Inquiry (ISI) may be used to estimate the number of scholarly articles written by an institution's faculty. We show how institutions are ranked according to total publications and the ratio of publications to full-time faculty, how these measures vary by type of institution, and how they are correlated with other selected measures of research resources and institutional quality.
Read moreNatural Uranium and Thorium Distributions in Podzolized Soils and Native Blueberry
Plant uptake of radionuclides is one of many vectors for introduction of contaminants into the human food chain. Thus, it is critical to understand soil-plant relationships that control nuclide bioavailability. Our objectives in this study were to (i) determine the extent of U and Th uptake and cycling by blueberry (Vaccinium pallidum Aiton) in native habitat and (ii) identify the soil properties and processes that contribute most to U and Th bioavailability in this system. We collected composite samples of plant leaves and stems, and samples from surface (AE) horizons and from the upper part of the Bs horizon at two sites. Concentration ratios (CRs) for U and Th were calculated for all plant tissues, using both the AE and Bs horizons as the base. Soil concentrations of U ranged from 16 to 25 microg g(-1), with a mean of 21.1 microg g(-1). Soil concentrations of Th ranged from 14 to 97 microg g(-1), with a mean of 41.8 microg g(-1). Mean U concentrations were 8.65 x 10(-3) microg g(-1) in leaf tissue, and 7.95 x 10(-3) microg g(-1) in stem tissue. Mean Th concentrations were 1.59 x 10(-1) microg g(-1) in leaf tissue, and 9.10 x 10(-2) microg g(-1) in stem tissue. Blueberry plants are cycling both U and Th in this system, with Th cycling occurring to a greater extent than U. In addition, Th was translocated preferentially to plant leaves while U concentrations showed little preferential translocation. Uranium uptake, however, seemed more sensitive than Th uptake to soil properties.
Read moreUsing Panel Data to Examine Legislative Demand for Higher Education
Empirical studies of legislative demand for higher education, using cross-sectional date for all 50 states, have not found much evidence that economic and demographic factors influence state higher education appropriations. This study uses panel data on state appropriations from 1982 through 1996 to examine the sensitivity of the results from the legislative demand model to changes in statistical methodology employed. The results show that the signs and significance levels of variables used in the legislative demand model vary widely when ordinary least squares, fixed effects and two-stage least squares are used. In particular, after controlling for state effects in the panel data, a number of the expected relationships between state appropriations and both economic and demographic factors emerge. There is also some evedence that K-12 education is a significant competing interest group for higher education, and that the legislative demand functions for higher education vary by geographical region and whether funding formulae are used to help determine higher education appropriations.
