An examination of the antecedents of readiness for fine-tuning and corporate transformation changes
No full textThis study examined employee readiness for fine-tuning changes and for corporate transformation changes. It was proposed that employees would report different degrees of readiness for these two types of change and that different variables would be associated with readiness for the two types of change. Results of regression analyses indicated that trust in peers and logistics and system support displayed strong positive relationships with readiness for fine-tuning changes, while trust in senior leaders and self-efficacy displayed strong positive relationships with readiness for corporate transformation changes. The implications of this study focus on the appropriateness of traditional change management strategies in light of findings that multiple change readiness attitudes exist within an organization
Hand-Scoring Error Rates in Psychological Testing
No full textDespite the comprehensive treatment of test validity in most technical manuals, test authors appear to routinely assume that clients and professionals will score their instruments without error. Recently Allard and Faust challenged this assumption by suggesting that error rates “may not be rare or benign” and demonstrated that tests with more complex scoring procedures were associated with a greater number of scoring errors. This study investigated error rates that resulted from hand scoring seven psychometric tests commonly employed in psychological practice. Significant and serious error rates were identified for both psychologist and client scorers across all tests investigated. Scoring complexity was found to predict the base rate of scorer errors. The findings suggest that greater development in and attention to test-scoring procedures is required to restrict the likelihood of scorer error
Institutionelle Reformen zur Friedenskonsolidierung
No full textAm 19. September 2012 veröffentlichte die Bundesregierung im Zusammenhang mit einer Strategie der Krisenprävention ressortübergreifende Leitlinien für eine kohärente Politik gegenüber fragilen Staaten. Darin gibt sie das Ziel aus, Staatlichkeit durch "institutionalisierte und rechtlich abgesicherte Mechanismen der gleichberechtigten politischen Teilhabe" zu fördern. Wissenschaftler, Diplomaten und Entwicklungspolitiker gehen zumeist davon aus, dass institutionelle Reformen zur Friedenskonsolidierung in Nachkriegsgesellschaften beitragen können. Es bleibt jedoch unklar, unter welchen Bedingungen solche Reformen Erfolg haben. Eine Analyse institutioneller Reformen in 18 Nachkriegsstaaten in den Bereichen territoriale Staatsstruktur, Wahl- und Parteiensysteme, Regierungssysteme, Sicherheitssektor und Justiz in den Jahren von 2000 bis 2005 deutet auf folgende Ergebnisse hin: Nationale und internationale Akteure müssen bei den Reformen die Wechselwirkungen der Institutionen untereinander und das gesamte "Konzert" der Institutionen berücksichtigen. Viel zu selten wird beachtet, dass Reformen in unterschiedlichen Politikbereichen sich gegenseitig widersprechen können oder zusammen eine Wirkung entfalten, die immer die gleichen "Reformverlierer" hervorbringt - das kann einen notwendigen Elitenkonsens untergraben. Reformüberlastung aufgrund vieler gleichzeitig reformierter Institutionen kann die Friedenskonsolidierung gefährden. Für den Erfolg institutioneller Reformen ist über die reine Festlegung in Friedensabkommen und/oder Verfassungen hinaus ihre effektive Umsetzung notwendig

A K-theoretic approach to Chern-Cheeger-Simons invariants
No full textsummary:The aim of this paper is to construct a natural mapping \check C\sb k, , from the multiplicative -theory of a differential manifold , associated to the trivial filtration of the de Rham complex, as defined by {\it M. Karoubi} in [C. R. Acad. Sci., Paris, S\'er. I 302, 321-324 (1986; Zbl 0593.55004)] to the odd cohomology H\sb s\sp{2k-1} (X;C\sp*). By using this mapping, the author associates to any flat complex vector bundle on characteristic classes \check C\sb k(E) \in H\sb{dR}\sp{2k-1} (X;C\sp*) analogous to the classes studied by {\it S. Chern}, {\it J. Cheeger} and {\it J. Simons} in [Differential characters and geometric invariants, in `Geometry and topology', Lect. Notes Math. 1167, 50-80 (1985; Zbl 0621.57010), Characteristic forms and geometric invariants, Ann. Math., II. Ser. 99, 48-69 (1974; Zbl 0283.53036)]
Psychologist hand scoring error rates on the Rothwell Miller Interest Blank: A comparison of three job allocation systems
No full textHand scoring errors are known to occur on a range of psychological tests. The present study conducts an investigation into the existence of scoring errors by 27 professional occupational psychologists using the Rothwell-Miller Interest Blank (RMIB; Miller, Tyler & Rothwell, 1994). Building on investigations into the impact of work allocation practices on work quality in other professions, this study explored whether psychologist scoring error rates differed between three work allocation systems. Data from 1175 completed RMIB survey forms indicated error rates for the three systems ranged from five to 16.3 percent, with the self-managed work allocation system resulting in the lowest error rate. The discussion focuses on possible ways for psychologists to overcome scoring error rates with the RMIB and the potential implications these results have for allocating case work to psychologists. Suggestions for test developers and organisations designing work allocation systems are proffered

Blow-up dynamics for radial self-dual Chern-Simons-Schrödinger equation with prescribed asymptotic profile
No full textWe construct finite energy blow-up solutions for the radial self-dual Chern-Simons-Schrödinger equation with a continuum of blow-up rates. Our result stands in stark contrast to the rigidity of blow-up of solutions proved by the first author for equivariant index , where the soliton-radiation interaction is too weak to admit the present blow-up scenarios. It is optimal (up to an endpoint) in terms of the range of blow-up rates and the regularity of the asymptotic profiles in view of the authors\u27 previous proof of soliton resolution for the self-dual Chern-Simons-Schrödinger equation in any equivariance class.
Our approach is a backward construction combined with modulation analysis, starting from prescribed asymptotic profiles and deriving the corresponding blow-up rates from their strong interaction with the soliton. In particular, our work may be seen as an adaptation of the method of Jendrej-Lawrie-Rodriguez (developed for energy critical equivariant wave maps) to the Schrödinger case.77 page
