The way to a high‐performance culture with the Total Performance Scorecard
Authors: Rampersad Hubert K. 
Published: May 2008

Abstract

A new blueprint for creating a highly engaged and happy workforce is needed, where personal and organizational performance and learning mutually reinforce each other on a sustainable basis. This paper introduces a new business management concept, called Total Performance Scorecard (TPS), defined as the systematic process of continuous, gradual, and routine improvement, development, and learning, focused on a sustainable increase of personal, organizational, and project performances. It stresses the importance and need to develop a high‐performance culture that combines the goals and aspirations of the individual with those of the company.

These concepts provide solutions to preserve and utilize individual rights and capabilities while adjusting the organizational culture and philosophy to this new environment. This has been done by expanding and integrating concepts such as the Personal Balanced Scorecard, Organizational Balanced Scorecard, Project Balanced Scorecard, Lean Six Sigma, and Talent Management into one overall holistic and organic framework.

This model will help organizations manage the demanding and often frustrating road toward sustained employee engagement and improvement.

Authors: Galdón Beatriz Rodríguez , González Rafael Oropeza , Rodríguez Elena Rodríguez , Romero Carlos Díaz 
Published: May 2008

AbstractBACKGROUND: P, Na, K, Ca, Mg, Fe, Cu, Zn, Mn and Se were determined in five traditional onion cultivars (Allium cepa L.) from Tenerife (Guayonje, San Juan de la Rambla, Carrizal Alto, Carrizal Bajo and Masca) and a commercial cultivar (Texas Early Grano 502) grown under the same agronomic, soil and climatic conditions in order to find out differences between these cultivars.RESULTS: Carrizal Alto presented the highest K content and lowest P, Na, Fe, Zn, Mn and Se. Texas cultivar had the highest P, Mg and Se contents, and the lowest contents of Ca, Cu and Mn. There were clear differences in the mineral and trace elements contents between the two seed origins of San Juan de la Rambla cultivar. Many correlations were found between the parameters analyzed, emphasizing the FeZn and CaMn correlations.CONCLUSION: There were differences in the mineral and trace element composition between the onion cultivars. The environment and agronomic practices could affect the genetic information of the seeds, determining changes in the mineral and trace element composition. Linear discriminant analysis is a useful tool for differentiating onion samples according to cultivar and seed origin. Copyright © 2008 Society of Chemical Industry
Parabolic finite volume element equations in nonconvex polygonal domains
Authors: Chatzipantelidis P. , Lazarov R.D. , Thomée V. 
Published: May 2008

AbstractWe study spatially semidiscrete and fully discrete finite volume element approximations of the heat equation with homogeneous Dirichlet boundary conditions in a plane polygonal domain with one reentrant corner. We show that, as a result of the singularity in the solution near the reentrant corner, the convergence rate is reduced from optimal second order, similarly to what was shown for the finite element method in the earlier work 2. Optimal order convergence may be restored by mesh refinement near the corners of the domain. © 2008 Wiley Periodicals, Inc. Numer Methods Partial Differential Eq, 2009
Unified multipliers‐free theory of dual‐primal domain decomposition methods
Authors: Herrera Ismael , Yates Robert A. 
Published: May 2008

AbstractThe concept of dual‐primal methods can be formulated in a manner that incorporates, as a subclass, the non preconditioned case. Using such a generalized concept, in this article without recourse to “Lagrange multipliers,” we introduce an all‐inclusive unified theory of nonoverlapping domain decomposition methods (DDMs). One‐level methods, such as Schur‐complement and one‐level FETI, as well as two‐level methods, such as Neumann‐Neumann and preconditioned FETI, are incorporated in a unified manner. Different choices of the dual subspaces yield the different dual‐primal preconditioners reported in the literature. In this unified theory, the procedures are carried out directly on the matrices, independently of the differential equations that originated them. This feature reduces considerably the code‐development effort required for their implementation and permit, for example, transforming 2D codes into 3D codes easily. Another source of this simplification is the introduction of two projection‐matrices, generalizations of the average and jump of a function, which possess superior computational properties. In particular, on the basis of numerical results reported there, we claim that our jump matrix is the optimal choice of the B operator of the FETI methods. A new formula for the Steklov‐Poincaré operator, at the discrete level, is also introduced. © 2008 Wiley Periodicals, Inc. Numer Methods Partial Differential Eq, 2009
Assembly of bioinspired helical protein fibers
Authors: Gunasekar Susheel Kumar , Haghpanah Jennifer Shorah , Montclare Jin Kim 
Published: May 2008

AbstractAdvances in protein and peptide technologies not only enable the study of basic folding and function of natural structures but also the design of novel scaffolds with the ability to form assemblies of varied shapes and sizes. Tremendous progress has been made in our understanding of α‐helices in nature especially in the context of the coiled‐coil. The information gleaned from investigating coiled‐ coils has been used to design novel α‐helical fibers with prescribed morphology and dimensions. This review focuses on the lessons learned from the assembly of natural coiled‐coils and how this knowledge can be used to tailor helical fibers as novel bioinspired materials.

Published: May 2008

AbstractMost GIST patients develop clinical resistance to KIT/PDGFRA tyrosine kinase inhibitors (TKI). However, it is unclear whether clinical resistance results from single or multiple molecular mechanisms in each patient. KIT and PDGFRA mutations were evaluated in 53 GIST metastases obtained from 14 patients who underwent surgical debulking after progression on imatinib or sunitinib. To interrogate possible resistance mechanisms across a broad biological spectrum of GISTs, inter‐ and intra‐lesional heterogeneity of molecular drug‐resistance mechanisms were evaluated in the following: conventional KIT (CD117)‐positive GISTs with KIT mutations in exon 9, 11 or 13; KIT‐negative GISTs; GISTs with unusual morphology; and KIT/PDGFRA wild‐type GISTs. Genomic KIT and PDGFRA mutations were characterized systematically, using complementary techniques including D‐HPLC for KIT exons 9, 11–18 and PDGFRA exons 12, 14, 18, and mutation‐specific PCR (V654A, D820G, N822K, Y823D). Primary KIT oncogenic mutations were found in 11/14 patients (79%). Of these, 9/11 (83%), had secondary drug‐resistant KIT mutations, including six (67%) with two to five different secondary mutations in separate metastases, and three (34%) with two secondary KIT mutations in the same metastasis. The secondary mutations clustered in the KIT ATP binding pocket and kinase catalytic regions. FISH analyses revealed KIT amplicons in 2/10 metastases lacking secondary KIT mutations. This study demonstrates extensive intra‐ and inter‐lesional heterogeneity of resistance mutations and gene amplification in patients with clinically progressing GIST. KIT kinase resistance mutations were not found in KIT/PDGFRA wild‐type GISTs or in KIT‐mutant GISTs showing unusual morphology and/or loss of KIT expression by IHC, indicating that resistance mechanisms are fundamentally different in these tumours. Our observations underscore the heterogeneity of clinical TKI resistance, and highlight the therapeutic challenges involved in salvaging patients after clinical progression on TKI monotherapies.

Ring‐opening metathesis polymerization of norbornene catalyzed by tantalum and niobium complexes with chelating O‐donor ligands
Authors: Nakayama Yuushou , Maeda Naoaki , Yasuda Hajime , Shiono Takeshi 
Published: May 2008

AbstractBACKGROUND: In comparison with group 6 transition metals, such as tungsten and molybdenum, and group 8 metal ruthenium, group 5 metal‐based catalysts for ring‐opening metathesis polymerization (ROMP) have remained much less studied. The few reported ROMP catalysts of group 5 metals require multiple reaction steps to be synthesized, and are highly sensitive to air and moisture.RESULTS: A series of pentavalent tantalum and niobium complexes having catecholato, tropolonato, hinokitiolato, biphenolato and binaphtholato ligands were prepared and their catalytic activities for the ROMP of norbornene (NBE) were studied in the presence of trialkylaluminium as a co‐catalyst. Among these complexes, the tantalum complexes showed high activity upon activation with Bui3Al. In sharp contrast, the niobium complexes were effectively activated with Me3Al. The polymers obtained with these complexes had high molecular weights (Mn > 105 g mol−1) and relatively narrow molecular weight distributions (Mw/Mn ≈ 2).CONCLUSION: We found that easily accessible and relatively stable tantalum and niobium complexes with such chelating O‐donor ligands showed high catalytic activity for ROMP of NBE depending on the kind of co‐catalyst. These findings could contribute to future development of ROMP catalysts. Copyright © 2008 Society of Chemical Industry
Anionic alternating copolymerization of 3,4‐dihydrocoumarin and glycidyl ethers: A new approach to polyester synthesis
Authors: Uenishi Kazuya , Sudo Atsushi , Endo Takeshi 
Published: May 2008

AbstractAnionic copolymerizations of 3,4‐dihydrocoumarin (DHCM) and a series of glycidyl ethers (n‐butyl glycidyl ether, tert‐butyl glycidyl ether, and allyl glycidyl ether) with 2‐ethyl‐4‐methylimidazole as an initiator proceeded in a 1:1 alternating manner to give the corresponding polyesters, whose structures were confirmed by spectroscopic analyses and reductive scission of the ester bonds in the main chain with lithium aluminum hydride, followed by detailed analyses of the resulting fragments. The polyester obtained by the copolymerization of DHCM and allyl glycidyl ether inherited the allyl groups in the side chain, whose applicability to chemical modifications of the polyester was successfully demonstrated by a platinum‐catalyzed hydrosilylation reaction. © 2008 Wiley Periodicals, Inc.

Designing of dipeptide‐based oligoconjugates as potential carrier for drug delivery. Pyroglutamil‐S‐glutamic acid bisoligo‐3‐hydroxybutyrates
Authors: Buruiana Emil C. , Kowalczuk Marek , Adamus Grazyna , Jedlinski Zbigniew 
Published: May 2008

AbstractIn the present article, we describe the synthesis and characterization of conjugates based on pyroglutamyl‐S‐glutamic acid and bisoligo‐[R,S]‐3‐hydroxybutyrates (PyGlu‐S_‐Glu_bisOHB) using anionic ring opening polymerization of β‐butyrolactone with a dipeptide bearing two carboxylate groups as potassium salt. The results indicated that the above‐mentioned reaction is accompanied of oligomerization of β‐butyrolactone yielding (3‐hydroxybutyrates) oligomers with crotonate and carboxyl end groups. We report also the end group analysis of the synthesized conjugates using electrospray ionization tandem mass spectrometry (ESI‐MS), the latter confirmed the presence of a mixture of dipeptide conjugate with β‐butyrolactone oligomer chain and β‐butyrolactone homopolymer. © 2008 Wiley Periodicals, Inc.

Exercise and relaxation intervention for breast cancer survivors: feasibility, acceptability and effects
Authors: Rabin Carolyn , Pinto Bernardine , Dunsiger Shira , Nash Justin , Trask Peter 
Published: May 2008

AbstractObjective: Although evidence mounts regarding the beneficial effects of physical activity (PA) interventions for breast cancer survivors, not all interventions have produced significant improvement in mood. Relaxation training may be a promising strategy for enhancing mood effects from these interventions. The goals of Be Calm and Move On were to assess the feasibility, acceptability and preliminary effects of a 12‐week combined PA and relaxation intervention for breast cancer survivors.Methods: Twenty‐three early‐stage breast cancer survivors were enrolled and 19 were retained for the intervention and 12‐ and 24‐week follow‐ups. Participants received a theoretically grounded intervention delivered via telephone.Results: Participant evaluations of the intervention indicated that it was feasible and acceptable (e.g. 100% would recommend it to others); objective data further supported its feasibility (e.g. 83% completed the trial, 91% of intervention calls were received). In addition, when comparing 12‐ and 24‐week follow‐up data to baseline data, participants demonstrated significantly increased PA, improved mood and sleep quality, and reduced fatigue (p's<0.05).Conclusion: Thus, this pilot study suggests that the intervention is feasible and acceptable and produces promising effects on mood, sleep, and fatigue.

AbstractThe 7th International Conference of Nitride Semiconductors (ICNS‐7) was held at the MGM Grand Hotel in Las Vegas, Nevada, USA, from 16–21 September 2007. A record number of more than 900 registered participants gathered in Las Vegas to hear the most recent developments in nitride semiconductors. A total of 694 papers, divided into more than 40 sessions, were presented at the conference covering every aspect of group‐III nitride semiconductor research. The title of the Plenary Talk given by Prof. Klaus H. Ploog, “III‐Nitrides Seem to Be Good for Everything, ” was indeed accurate.The present issue of physica status solidi contains more than 300 peer‐reviewed scientific papers describing the state‐of‐the‐art in nitride semiconductor materials and devices, as presented at ICNS‐7. The diligent work of the many authors and referees involved in these proceedings (more than 400) has been fundamental for the successful completion of this important record of the conference.Finally, the conference organizers would also like to acknowledge and thank the many sponsors and public agencies that have financially supported ICNS‐7. Without their help, ICNS‐7 would have never become the largest nitride conference ever. Thank you also to all the participants who, with their papers and discussions, have made ICNS‐7 a tremendous success. We look forward to new exciting developments in nitride semiconductors at ICNS‐8 in Jeju Island, Korea, in October 2009. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Organisch bandbeschichtetes Stahl‐Feinblech – Ein Produkt mit besonderem Korrosionsschutz
Authors: Nabbefeld‐Arnold Erich 
Published: May 2008

AbstractOrganisch bandbeschichtete Stahlfeinbleche sind Halbzeuge mit einer fertigen Oberfläche, aus denen Bauteile mit einem hohen Gebrauchswert hergestellt werden. Aufgrund ihres optimierten Werkstoffaufbaus werden sowohl funktionale und als auch dekorative Aspekte realisiert. Die Flacherzeugnisse besitzen durch ihren mehrschichtigen Aufbau einen hohen Korrosionswiderstand, der die wichtige funktionale Basis für dünnwandige Bauelemente schafft. Die jeweiligen Schichten besitzen aktive und passive Eigenschaften für den Korrosionsschutz – der kathodische Schutz ist hierbei der Wichtigere. Konstruktive Maßnahmen verstärken den Schutz gegen die negativen Einflüsse des Wetters.Infolge der DIN 55928‐8 wurde ein hohes Qualitätsniveau des Korrosionsschutzes u.a. durch die Festlegung von Eigenschaftsanforderungen sowie durch Eigen‐ und Fremdüberwachungen gesichert. Dieser Tradition folgt auch die Nachfolgenorm DIN 55634, deren Entwurf im Frühjahr 2008 veröffentlicht wird.Durch die beständige und flexible organische Beschichtung des Flacherzeugnisses werden auch dekorative Aspekte, wie z. B. Formgebung sowie Farbe und Glanz, verwirklicht. Durch eine differenzierte Farbgestaltung erhalten riesige Baukörper von Industrieanlagen über ihre Fassade ein freundliches und lebendiges Aussehen. Leichtbauelemente aus organisch bandbeschichtetem Feinblech ermöglichen Unternehmen, Öffentlichkeitsarbeit für nachhaltiges Bauen zu betreiben.
Spontaneous compartment syndrome in a patient with diabetes and statin administration: a case report
Authors: Flamini Stefano , Zoccali Carmine , Persi Emanuele , Calvisi Vittorio 
Published: May 2008

Abstract
Compartment syndrome is a condition characterized by pressure increasing in the inextensible muscular compartments that leads to a decrease of capillary perfusion with consequent ischemic lesions of the logia elements. The authors report a case of an unusual compartment syndrome with spontaneous onset in a patient with type II diabetes and chronic therapy with statins (Atorvastatin). The condition was successfully treated by a fasciotomy and medical support. The importance of a correct anamnesis and a high level of suspicion is emphasized.
Soil clay content and fire frequency affect clustering in trees in South African savannas

Published: May 2008

Abstract:In this paper, we investigate which factors determine tree clustering in Southern African savannas. This was tested by measuring clustering of trees using the T-squared sampling method in plots of the Kruger National Park experimental burning programme in South Africa. Fire return interval is the main treatment in these plots, but also several auxiliary determining parameters like clay content in the soil, diameter of tree canopies, understorey composition, tree species diversity and average annual rainfall were measured while sampling. In the Kruger National Park 48 plots distributed over four different landscape types and with three different burning treatments (never, once every 3 y and annually) were sampled. First, we related the clustering of trees to these environmental variables. When looking at the most abundant species in each plot, the analysis revealed that clustering is mainly correlated with clay content in the soil. This analysis also showed that fire frequency had a positive effect on the clustering of tree species that are not very abundant. We suggest that less abundant species might be less resistant to fire and therefore adopt a mechanism of clustering to exclude grass fires under their canopy. Finally, we tested the effect of clustering on the impact of fire on trees by analysing the relationship between the distance of a tree to its nearest neighbour and its canopy diameter. We found that clustering reduces the damaging effect of fire on trees. Our study contributes to understanding of savanna functioning by showing which processes are relevant in the distribution of savanna trees.
Differential effects of mammalian seed predators on the regeneration of five Papua New Guinean tree species and implications for sapling recruitment
Authors: Jones Elizabeth R. , Curran Lisa M. , Wright Debra D. , Mack Andrew L. 
Published: May 2008

Abstract:Although herbivores may account for a significant source of seed and seedling mortality in many tropical tree species, plant species differ in their response to seed damage. Here we investigate the relative effects of seed predation on the regeneration of five tree species in a mid-elevation Papua New Guinean rain forest. Exclosure treatments and shade-house experiments were monitored from November 2004 to March 2006 to assess the differential effects of seed predation on seed viability and seedling growth. Results indicate that although seed predators attack all five focal species, they influence the seedling populations in two, Cerbera floribunda and Microcos grandiflora, and minimally affect the seedling populations of Terminalia impediens, Pandanus penicillus and Endiandra latifolia in the years measured. Predation and germination frequencies were compared to the abundance of focal species at several life stage classes to explore potential correlations between species-specific seed mortality patterns and life stage distributions. We found that the species-specific influence of mammalian seed predators correlated with abundance distributions in three life stages. Species with high survivorship after seed predator attacks displayed a significant decrease in abundance from the seedling-to-sapling transition, while those species with high seed mortality demonstrated relatively even distributions of seedlings, saplings and adults (> 10 cm dbh). These contrasting patterns suggest that differential seed predation effects on regeneration may play a key role in the recruitment of individuals to the sapling stage.
Plant litter decomposition and nutrient cycling in north Queensland tropical rain-forest communities of differing successional status
Authors: Parsons Scott A. , Congdon Robert A. 
Published: May 2008

Abstract:Soil processes are essential in enabling forest regeneration in disturbed landscapes. Little is known about whether litterfall from dominating pioneer species in secondary rain forest is functionally equivalent to that of mixed rain-forest litter in terms of contribution to soil processes. This study used the litterbag technique to quantify the decomposition and nutrient dynamics of leaf litter characteristic of three wet tropical forest communities in the Paluma Range National Park, Queensland, Australia over 511 d. These were: undisturbed primary rain forest (mixed rain-forest species), selectively logged secondary rain forest (pioneerAlphitonia petriei) and tall open eucalypt forest (Eucalyptus grandis). Mass loss, total N, total P, K, Ca and Mg dynamics of the decaying leaves were determined, and different mathematical models were used to explain the mass loss data. Rainfall and temperature data were also collected from each site. The leaves ofA. petrieiandE. grandisboth decomposed significantly slowerin situthan the mixed rain-forest species (39%, 38% and 29% ash-free dry mass remaining respectively). Nitrogen and phosphorus were immobilized, with 182% N and 134% P remaining inE. grandis, 127% N and 132% P remaining inA. petrieiand 168% N and 121% P remaining in the mixed rain-forest species. The initial lignin:P ratio and initial lignin:N ratio exerted significant controls on decomposition rates. The exceptionally slow decomposition of the pioneer species is likely to limit soil processes at disturbed tropical rain-forest sites in Australia.
