Aim/Purpose: This research aims to develop an information technology (IT) maturity model for incident management (IM) process that merges the most known IT frameworks’ practices. Our proposal intends to help organizations overcome the current limitations of multiframework implementation by informing organizations about frameworks’ overlap before their implementation. Background: By previously identifying frameworks’ overlaps it will assist organizations during the multi-framework implementation in order to save resources (human and/or financial). Methodology: The research methodology used is design science research (DSR). Plus, the authors applied semi-structured interviews in seven different organizations to demonstrate and evaluate the proposal. Contribution: This research adds a new and innovative artefact to the body of knowledge. Findings: The proposed maturity model is seen by the practitioners as complete and useful. Plus, this research also reinforces the frameworks’ overlap issue and concludes that some organizations are unaware of their actual IM maturity level; some organizations are unaware that they have implemented practices of other frameworks besides the one that was officially adopted. Recommendations for Practitioners: Practitioners may use this maturity model to assess their IM maturity level before multi-framework implementation. Moreover, practitioners are also incentivized to communicate further requirements to academics regarding multi-framework assessment maturity models. Recommendation for Researchers: Researchers may explore and develop multi-frameworks maturity models for the remaining processes of the main IT frameworks. Impact on Society: This research findings and outcomes are a step forward in the development of a unique overlapless maturity model covering the most known IT frameworks in the market thus helping organizations dealing with the increasing frameworks’ complexity and overlap. Future Research: Overlapless maturity models for the remaining IT framework processes should be explored.

We present a new approach to explain the fact that the frictional force does no work when a body rolls without slipping. The description proposed is accurate and provides a straightforward explanation that could be used by students.

By means of an example that could be used to stimulate discussion among students, we deal with different fundamental ideas related to rolling motion and give several didactic suggestions on the subject. In addition, using numerical calculations, we study the motion described by a spool when the force applied is directed constantly towards a fixed point. In general, the resulting motion is oscillatory. When small oscillations are considered, the spool behaves as a simple harmonic oscillator. In order to show the oscillatory behaviour predicted by the numerical calculation, we have designed an experimental device similar to the one considered in the theoretical model, in which the oscillatory motion was observed. Resumen. Por medio de un ejemplo que podría ser útil para estimular discusiones entre los alumnos, estudiamos algunas ideas fundamentales relacionadas con el movimiento de rodadura, y proponemos diversas sugerencias didácticas sobre este problema. Además, utilizando cálculo numérico, estudiamos el movimiento descrito por un carrete cuando la fuerza aplicada está dirigida constantemente hacia un punto fijo. En general, el movimiento resultante es oscilatorio. Si se consideran oscilaciones pequeñas, el sistema se comporta obviamente como un oscilador armónico simple. Con objeto de ilustrar el comportamiento oscilatorio que se obtiene a partir de los cálculos numéricos, hemos diseñado un dispositivo experimental similar al considerado en el modelo teórico en el que hemos observado el movimiento oscilatorio descrito por el carrete.
