Effects of Leadership Style, Creativity Technique and Personal Initiative onEmployee Creativity

Daniel Herrmann*and Jrg FelfeArticle first published online: 29 OCT 2012 DOI: 10.1111/j.1467-8551.2012.00849.x 2012 The Author(s). British Journal of Management 2012 British Academy of Management

AbstractTransformational leadership is assumed to enhance employees' creativity. However, results of

meta-analytic research on the relations between transformational leadership and creativity havefallen short of expectations. The authors argue that, besides leadership style, the creativitytechnique that a leader employs is an important means of stimulating employees' creativity. In

addition, it is assumed that leadership styles and creativity techniques may have different effects,depending on the measure of creativity output (quantitative vs qualitative). Therefore, in anexperimental setting, the effects of different creativity techniques (provocation technique vsbrainwriting) and leadership styles (transformational vs transactional) on both quantitative andqualitative creativity were examined. Results showed that transformational leadership andprovocation technique led to higher levels of qualitative creativity than transactional leadershipand brainwriting, respectively. Conversely, transactional leadership and brainwriting were moreeffective for quantitative creativity. The additional benefit of the provocation technique inqualitative creativity was found to be higher in the transactional leadership condition than in thetransformational leadership condition. Moreover, personal initiative made a significant andindependent contribution to both qualitative and quantitative creativity. Implications for practiceand future research are discussed.

Correlations of supercritical temperature of fluid alkali metals

Ramasamy Balasubramanian*Article first published online: 8 FEB 2008 DOI: 10.1002/apj.107Copyright 2008 Curtin University of Technology and John Wiley & Sons, Ltd.

AbstractThe supercritical temperature, the maximum attainable temperature of superheating and the

critical compressibility factor of caesium, rubidium and potassium are correlated through thegeneralised van der Waals equation of state. This three-parameter equation differs from theknown van der Waals equation of state by the modified expression for molecular pressure. Forcaesium, rubidium and potassium, the ratios of the supercritical temperature to the maximumattainable temperature of superheating are estimated. Our estimation results are in agreementwith experimental data. It has been established that caesium, rubidium and potassium obey thesingle-parameter law of corresponding states with the ratio of the supercritical temperature tothe maximum attainable temperature of superheating as the thermodynamic similarityparameter.

2. A raz de lo que ley en este captulo. Cules seran las diferencias entre ambos estudios?

La principal diferencia es en el anlisis de datos y resultados, mientras que en el cualitativoson sumamente subjetivos y relacionados directamente a percepciones, el cuantitativo trata datosnumricos y los analiza de manera objetiva, correlacionando datos, experimentos y resultadosmediante correlaciones.

El estudio cuantitativo puede considerarse ms fcil de reproducir, ya que los factores ycondiciones se pueden proveer fcilmente en equipo avanzado o dentro de un laboratorio, encambio en el artculo cualitativo se trata con personas, por lo que analizar el caso en un lugarcon gente con cierta cultura y hbitos especficos cambia radicalmente al hacerlo con gentedistinta, por lo que los resultados podran ser diametralmente opuestos.

En el estudio cualitativo se manejan conceptos que son difciles de medir, como la creatividady el liderazgo, en cambio en el estudio cuantitativo todos los parmetros y resultados se basanen mediciones.
