Women’s Everyday Creative Activities: a Qualitative Study

Abstract

The objective is to analyze manifestations of everyday creativity from the perspective of a group of women. We are interested in recovering the voices of the participants to understand constructed meanings regarding the actions, emotions, relations and contexts to unfolding processes of everyday creativity. We conducted a qualitative study, in which 20 Argentine women aged between 21 and 69 years participated. The sampling was not probabilistic, intentional and for convenience. The participants reside in cities of intermediate size, namely Córdoba, San Luis and Mendoza (Argentina). They reported daily, during one week, on the creative activities in which they were engaged in their lives. The process of data collection was done through WhatsApp; participants sent texts, audios, videos and photographs. We codified and analyzed the data with the QDA MINER LITE program. We constructed four categories of analysis: doing creative things; others and creative contexts; emotions in play and creative self-belief. The results indicate that people relate creativity to different types of work (cooking, handicrafts, academic activities, artistic workshops, solving daily problems, etc.). Others play an important role in creativity as the recipients of creative work, collaborative co-workers or helpers that facilitate creative tasks. The development of everyday creative activities is also linked to well-being and positive emotions (pleasure, passion, desire, satisfaction, self-realization and personal expression). We highlight the importance of creative identity as a complex construction of expectations, self-evaluations and metacognitive processes. The research contributes to the understanding of everyday creativity as a factor that promotes health and the empowerment of women.

A neutron track etch detector for electron linear accelerators in radiotherapy

A neutron track etch detector for electron linear accelerators in radiotherapy

Background. Electron linear accelerators in medical radiotherapy have replaced cobalt and caesium sources of radiation. However, medical accelerators with photon energies over 10 MeV generate undesired fast neutron contamination in a therapeutic X-ray photon beam. Photons with energies above 10 MeV can interact with the atomic nucleus of a high-Z material, of which the target and the head of an accelerator consist, and lead to the neutron ejection.

Results and conclusions. Our neutron dosimeter, composed of the LR-115 track etch detector and boron foil BN-1 converter, was calibrated on thermal neutrons generated in the nuclear reactor of the Josef Stefan Institute (Slovenia), and applied to dosimetry of undesirable neutrons in photon radiotherapy by the linear accelerator 15 MV Siemens Mevatron. Having considered a high dependence of a cross-section between neutron and boron on neutron energy, and broad neutron spectrum in a photon beam, as well as outside the entrance door to maze of the Mevatron, we developed a method for determining the effective neutron detector response. A neutron dose rate in the photon beam was measured to be 1.96 Sv/h. Outside the Mevatron room the neutron dose rate was 0.62 μSv/h. PACS: 87.52. Ga; 87.53.St; 29.40.Wk.
