This paper is part of a multiwavelength study aimed at using complementary photometric, polarimetric and spectroscopic data to achieve an understanding of the activity process in late-type stars. Here, we present the study of FR Cnc, a young, active and spotted star. We performed analysis of All Sky Automated Survey 3 (ASAS-3) data for the years 2002–08 and amended the value of the rotational period to be 0.826518 d. The amplitude of photometric variations decreased abruptly in the year 2005, while the mean brightness remained the same, which was interpreted as a quick redistribution of spots. BVR_C and I_C broad-band photometric calibration was performed for 166 stars in FR Cnc vicinity. The photometry at Terskol Observatory shows two brightening episodes, one of which occurred at the same phase as the flare of 2006 November 23. Polarimetric BVR observations indicate the probable presence of a supplementary source of polarization. We monitored FR Cnc spectroscopically during the years 2004–08. We concluded that the radial velocity changes cannot be explained by the binary nature of FR Cnc. We determined the spectral type of FR Cnc as K7V. Calculated galactic space-velocity components (U, V, W) indicate that FR Cnc belongs to the young disc population and might also belong to the IC 2391 moving group. Based on Li Iλ6707.8 measurement, we estimated the age of FR Cnc to be between 10 and 120 Myr. Doppler tomography was applied to create a starspot image of FR Cnc. We optimized the goodness of fit to the deconvolved profiles for axial inclination, equivalent width and v sin i, finding v sin  i=46.2 km s^−1 and i= 55°. We also generated a syntheticV-band light curve based on Doppler imaging that makes simultaneous use of spectroscopic and photometric data. This synthetic light curve displays the same morphology and amplitude as the observed one. The starspot distribution of FR Cnc is also of interest since it is one of the latest spectral types to have been imaged. No polar spot was detected on FR Cnc.

Novel or story adaptations and also dramatic texts versions, that need to be translated and updated to modern audiences are quite frequent in today`s theatre. This study aims to show the state of contemporary stage adaptation of narrative texts and, specifically, its evolution in Spain in the last forty years (1972-2012). To do this, I have tried to gather, first, all the terminology associated with the concept of stage adaptation: version, dramaturgy, rewriting, translation, interpretation, updating and consolidation. The theoretical part of the work begins with the various definitions of the concept of dramatization. All the positions reflected by theorists and specialists in the field come together when explaining the term adaptation or theatre version: the intervention on the original text is based on the transformation or change, radical or superficial, for its effective representation in the theatre. In contemporary times, the concept of adaptation applies to any kind of intervention, from the translation of the original (and rewriting) to the dramaturgical work involved in creating a new sense. In turn, any theatre adaptation requires a dramaturgical operation and supports all possible moves: reorganization of the story, breakage, reduced characters, dramatic concentration, incorporation of foreign texts, installation and collage, changes to the plot, etc. Although there is no definitive model for the theatre adaptation of works, several authors and theatrical theorists propose guidelines and types of adaptation to the transformation of a work into another or one genre into a different one; and regarding narrative texts, provide criteria for interpreting the original text. The issue for many authors is the danger of modifying or betraying the sense or the form of the original text, considering it as simple material for the play. Finally, it follows that there is affinity of thought among authors finding that there is no differentiation between adaptation and version: both terms refer to the same in the theatrical event and are also terms used equally for the countless film adaptations of novels and plays...
