Coaching political leaders: Can coaching be used to improve the quality of executive‐level government?
Authors: Browde Beth 
Published: June 2011

AbstractIn the corporate world, leadership development programs are standard fare. Such programs often include well‐defined competencies and performance metrics, as well as regularly scheduled feedback and mentoring sessions, especially for those employees designated “high potential” performers.Not so in the public sphere. There are no defined career paths or standardized training curricula for heads of
state. There are, however, requisite competencies for effective public sector leadership. As Gardner (1990) observed, “Leadership is not a mysterious activity. It is possible to describe the tasks that leaders perform....[But] we have barely scratched the surface in our efforts toward leadership development” (p. xix).The learning curve is steep for a newly elected leader, and fraught with potential landmines. Speaking with
the candor of someone no longer seeking public office, former UK Prime Minister Tony Blair said recently, “When I came to office, prime minister was the only job I'd ever held; I'd never been a government minister before....The business of running a government is like anything else: You get better the longer you do it. And there are lessons out there that, had they come to me in an identifiable form, would have been useful to know” (talk given on December 16, 2010b).Both Gardner and Blair are emphatic that leadership is not something one is born with but something learned
over time. And as Blair (2010a) put it, “Government is a race between expectations and capability.”In the essays that follow, several leadership coaches discuss the unique challenges and effective approaches
they are using to help government leaders build the competencies that will enable them to govern effectively—and win that race between their constituents's expectations and their own capabilities.

Published: June 2011

AbstractThe novel surface imprinted polymer composites (MIP/K2Ti4O9) were prepared using dibenzothiophene (DBT) as the template, 4‐vinylpyridine as the functional monomer and potassium tetratitanate whisker (K2Ti4O9) as the carrier. The synthetic product was characterized by Fourier transform infrared spectroscopy and scanning electron microscopy. Parameters influencing DBT adsorption such as contact time, temperature and DBT initial concentration were investigated. The adsorption kinetics were evaluated with the pseudo‐first‐order and pseudo‐second‐order models, and the adsorption isotherms were fitted by Langmuir and Freundlich models. Selectivity experiments showed that MIP/K2Ti4O9 exhibited excellent recognition capacity and binding affinity to DBT compared with the comparative substrates. MIP/K2Ti4O9 could also be easily regenerated and reused ten times with only about 20% loss of adsorption capacity.

Published: June 2011

AbstractA brush‐like copolymer consisting of poly(ethylene glycol) methyl ether methacrylate and N,N‐dimethylacrylamide (PEGMA‐DMA) was synthesized and used as a novel static physically adsorbed coating for protein separation by capillary electrophoresis for the first time, in order to stabilize electroosmotic flow (EOF) and suppress adsorption of proteins onto the capillary wall. Very stable and low EOF was obtained in PEGMA‐DMA‐coated capillary at pH 2.2–7.8. The effects of molar ratio of PEGMA to DMA, copolymer molecular mass, and pH on the separation of basic proteins were discussed. A comparative study of bare capillary with PEGMA‐DMA‐coated capillary for protein separation was also performed. The basic proteins could be well separated in PEGMA‐DMA‐coated capillary over the investigated pH range of 2.8–6.8 with good repeatability and high separation efficiency because the copolymer coating combines good protein‐resistant property of PEG side chains with excellent coating ability of PDMA‐contained backbone. Finally, the coating was successfully applied to the fast separation of other protein samples, such as protein mixture and egg white, which reveals that it is a potential coating for further proteomics analysis.
Lead shot ingestion by mourning doves on a disked field
Authors: Plautz Stephanie C. , Halbrook Richard S. , Sparling Donald W. 
Published: June 2011

AbstractPrevious field studies of hunter‐harvested mourning doves (Zenaida macroura) have reported the percentage of birds with ingested lead shot as 0.2–6.5%. To reduce the uncertainty concerning the number of doves that ingest shot, we conducted an experiment to test the proportion of mourning doves that ingested lead shot on the bare soil of a disked field (typical of a managed dove field) to simulate more natural feeding conditions. In each of 3 treatment groups of 80 birds, we exposed 35 birds to low‐density lead shot (1.5 million shot/ha), and35 birds to high‐density lead shot (29.5 million shot/ha), and 10 birds served as controls (no shot). We dosed 5 positive control birds with 2 lead shot each in trials 2 and 3. We scattered lead shot and mixed seed on the loosely packed soil of treatment cages and after 4 days of exposure, 2.9% of doves voluntarily ingested ≥1 lead shot. The proportion of birds that ingested shot when exposed to the high‐density shot treatment (4.9%) was not different (P = 0.098) from that of the low‐density shot treatment (1.0%). Lead concentrations in liver, kidneys, and blood reached maxima of 94.402 ppm, 346.033 ppm, and 13.883 ppm wet mass, respectively. Differences in delta‐aminolevulinic acid dehydratase (ALAD) activity, packed cell volume, and heterophil:lymphocyte ratio (H:L) were greater posttreatment in doves that had ingested shot than in those that did not. The risk posed to mourning doves from lead shot ingestion can be reduced by banning lead shot on management areas or dove fields or disking fields after hunting season to reduce shot availability. © 2011 The Wildlife Society.
Effects of mesopredators and prescribed fire on hispid cotton rat survival and cause‐specific mortality
Authors: Conner L. Mike , Castleberry Steven B. , Derrick Anna M. 
Published: June 2011

AbstractControl of mid‐sized mammalian predators (hereafter, mesopredators) is sometimes advocated in an attempt to reduce their impact on wildlife populations, particularly economically important (i.e., game) or endangered species. However, mesopredators may play a role in regulating small mammal populations; thus, lethal control of mesopredators may have unintended consequences. The hispid cotton rat (Sigmodon hispidus; hereafter, cotton rat) is one of the most common small mammals in the southeastern United States and is an important prey species for several of the region's predators. Within fire‐maintained communities, such as the longleaf pine (Pinus palustris) forests of the Coastal Plain, cotton rat populations dramatically, yet temporarily, decline following prescribed fire. To evaluate the effects of mesopredator removal on cotton rat survival and cause‐specific mortality, we conducted a large‐scale mesopredator exclusion experiment that incorporated a prescribed fire during the winter of study. Between 18 May 2006 and 20 June 2007, we used radio‐telemetry to monitor 252 cotton rats (131 in exclosures and 121 in controls) and documented 184 mortalities. During the 37‐week period of monitoring prior to the prescribed fire event, weekly survival of cotton rats was greater in mesopredator exclusion plots. During the 19 weeks following the prescribed fire, there were no differences in weekly survival relative to mesopredator treatment, but fire caused a short‐term reduction in weekly survival within both exclosures and controls. Of 36 cotton rats monitored on the date of prescribed fire, 18 were depredated within 1 month, 4 emigrated, and 5 were killed by the fire event. Overall, raptors preyed on cotton rats more in exclosures than in controls, but evidence for compensatory predation (raptor‐caused morality greater in exclosures than in controls although survival rates were similar between treatments) only occurred following the prescribed fire event. Our results suggest that managing mesopredators may result in a temporary increase in cotton rat survival, but dormant season prescribed fire removes this effect until well into the following growing season. © 2011 The Wildlife Society.
Maintaining populations of terrestrial wildlife through land management planning: A case study

Published: June 2011

AbstractRegulations and directives associated with enabling legislation for management of national forests in the United States require maintenance of viable populations of native and desired non‐native wildlife species. Broad‐scale assessments that address ecosystem diversity cover assessment of viability for most species. We developed an 8‐step process to address those species for which management for ecosystem diversity may be inadequate for providing ecological conditions capable of sustaining viable populations. The process includes identification of species of conservation concern, description of source habitats, and other important ecological factors, grouping species, selection of focal species, development of focal species assessment models, development of conservation strategies, and designing monitoring, and adaptive management plans. Following application of our screening criteria, we identified 209 of 700 species as species of conservation concern on National Forest System lands east of the crest of the Cascade Mountains in Oregon and Washington State, USA. We aggregated the 209 species of conservation concern into 10 families and 28 groups based primarily on habitat associations (these are not phylogenetic families). We selected 36 primary focal species (78% birds, 17% mammals, 5% amphibians) for application in northeast Washington State, USA based on risk factors and ecological characteristics. Our assessment documented reductions in habitat capability across northeast Washington State compared to historical conditions. To address such changes, for each focal species we developed conservation strategies that included habitat protection and restoration and amelioration of threats. We combined conservation strategies for individual species with other focal species and with management proposals for other resources (e.g., recreation, fire, and fuels management) to develop a multi‐species, multi‐resource management strategy. The information generated from our approach can be directly translated into land management planning through development of desired conditions, objectives, and standards and guidelines to improve the probability that desired population outcomes will be achieved. However, it should be noted by practitioners that a practical conservation planning process, such as ours, cannot remove all uncertainty and risk to species viability. © 2011 The Wildlife Society.
Energy development affects populations of sagebrush songbirds in Wyoming
Authors: Gilbert Michelle M. , Chalfoun Anna D. 
Published: June 2011

AbstractOil and natural gas development in the Intermountain West region of North America has expanded over the last 2 decades, primarily within sagebrush dominated landscapes. Although the effects of energy development on high‐profile game species such as the greater sage‐grouse (Centrocercus urophasianus) have been documented, studies examining responses of non‐game birds are lacking. Simultaneously, many songbirds that breed within sagebrush steppe habitats have shown range‐wide population declines that are likely due to widespread habitat loss and alteration. We evaluated songbird abundance and species richness across gradients of oil and natural gas development intensity, as indexed by well density, at 3 energy fields (2 natural gas and 1 oil) in the Upper Green River Basin, Wyoming, USA during 2008–2009. While simultaneously accounting for important habitat attributes, increased well density was associated with significant decreases in Brewer's sparrow (Spizella breweri) and sage sparrow (Amphispiza belli) abundance, particularly in the Jonah natural gas field. Vesper sparrows (Pooecetes gramineus) were also negatively influenced by increased well density. Horned larks (Eremophila alpestris) increased with well density in the Pinedale Anticline natural gas field, and sage thrashers (Oreoscoptes montanus) showed no response to energy development. Species richness was not significantly affected by well density. Results suggest that regional declines of some songbird species, especially sagebrush‐obligates, may be exacerbated by increased energy development. Understanding the specific mechanisms underlying responses to energy development is an important next step and will aid land managers in the development of effective mitigation and management strategies for the maintenance of stable bird communities in sagebrush habitat. © 2011 The Wildlife Society.
Effects of large‐scale removal of coyotes on pronghorn and mule deer productivity and abundance
Authors: Brown Dylan E. , Conover Michael R. 
Published: June 2011

AbstractWe tested the hypothesis that predation by coyotes (Canis latrans) impacts pronghorn (Antilocapra americana) and mule deer (Odocoileus hemionus) populations. We did so by examining the effects of coyote removal on pronghorn and mule deer populations within 12 large areas (>10,500 km2) located in Wyoming and Utah during 2007 and 2008. Pronghorn productivity (fawn to adult female ratio) and abundance were positively correlated with the number of coyotes removed and removal effort (hours spent hunting coyotes from aircraft) although the correlation between pronghorn productivity and removal effort was not statistically significant (P = 0.08). Mule deer productivity and abundance were not correlated with either the number of coyotes removed or removal effort. Coyote removal conducted during the winter and spring provided greater benefit than removals conducted during the prior fall or summer. Our results suggest that coyote removal conducted over large areas increases fawn survival and abundance of pronghorn but not mule deer. © 2011 The Wildlife Society.
Are you “Humbitious” enough to lead?
Authors: Taylor William C. 
Published: June 2011

AbstractLeaders are too often expected to fulfill a heroic model: know everything, run from morning till night, and make all key decisions‐all the while maintaining their sanity. Of course, this vision has long been obsolete. What is needed, Taylor says, is not heroic leadership but “humbitious” leadership, which blends ambition with humility. He offers critical insights on becoming more humbitious, so that you can succeed as a leader without losing your mind.
Six ingredients for collaborative partnerships
Authors: Kayser Thomas 
Published: June 2011

AbstractNew and experienced managers alike often lack the necessary mental maps and skills needed to be collaborative leaders capable of building effective partnerships within and across work teams. The author explains how three structural ingredients (shared goals, interdependence and complementary skills, and accountability) along with three behavioral characteristics (character, commitment, and authentic communication) can produce a multiplier effect that produces the synergy inherent in genuine collaborative partnerships.
Amphiphilic Block Copolymer from Hydroxyl‐Terminated Polymers Functionalized with TEMPO. A New Synthetic Method Using Oxoammonium Salt

Published: June 2011

AbstractA simple approach for the end‐functionalization of hydroxyl‐terminated polymers with nitroxide moieties using oxoammonium salts (OS) is presented. The functionalization is carried out using only one synthetic pathway in which high levels of functionalization (90%) are found. A mechanism for the functionalization with TEMPO moieties using OS is proposed in which the formation of peroxide groups is suggested. The structures of the functionalized polymers are characterized in detail by 1H NMR, 13C NMR, DQF‐COSY, and HETCOR. Bifunctional macroalkoxyamines are used to demonstrate how to extend the polymer chain for the synthesis of amphiphilic triblock copolymers by polymerizing St in a second block mediated by a nitroxide radical which provides the block length control. magnified image
Selective Localization Behavior of Carbon Nanotubes: Effect on Transesterification of Immiscible Polyester Blends

Published: June 2011

AbstractThe selective localization of carbon nanotubes (CNTs) in an immiscible polymer blend has attracted much attention. If the two component polymers could react with each other, do selectively located CNTs affect those reactions? Here, an immiscible polyester blend based on polycarbonate/poly(trimethylene terephthalate) (PC/PTT) is studied. CNTs introduced during melt mixing are selectively located in the PTT phase and on the phase interface during the middle stage of melt mixing. The interface‐located CNTs can act as additional substrate to catalyze or even participate in the transesterification themselves, homogenizing the phase morphology of the matrix blend. The degree of randomness of the composite systems is increased, accompanied by a reduced number‐average length of the copolymer sequences. magnified image

Published: June 2011

AbstractThe error of approximation by families of linear trigonometric polynomial operators in the scale of Lp‐spaces of periodic functions with 0 < p ⩽ +∞ is characterized with the help of realization functionals associated with operators of multiplier type describing smoothness properties of functions. The results are formulated in terms of generators of the family and of the smoothness. Applications of the general scheme to approximation methods generated by classical kernels as well as some new constructions describing smoothness of odd orders via approximation are given. © 2011 WILEY‐VCH Verlag GmbH & Co.

Some distributions for I‐segments of planar random homogeneous STIT tessellations
Authors: Mecke J. , Nagel W. , Weiß V. 
Published: June 2011

AbstractA tessellation‐valued process is considered, the random states of which are planar random homogeneous tessellations stable under iteration (STIT). It can be interpreted as a process of subsequent division of cells by random chords. These chords, referred to as I‐segments, have a length and a birth time. In the present paper the joint distribution of the length and the birth time of the typical I‐segment for isotropic STIT tessellations is given. Furthermore, later occurring chords have their endpoints in the relative interior of an I‐segment and thus generate a node of the tessellation. The distribution of the number of nodes in the relative interior of the typical I‐segment is studied. © 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim
