The purpose of this paper is to describe the perceptions that older people in Argentina have about the use of cell phones and to analyze their influence on user behavior. At the same time, it was intended to analyze whether sociodemographic factors influence these perceptions.

The authors conducted a study with a non-experimental, cross-sectional and cross-correlational design; a non-probabilistic sample of 138 intentionally selected older people was chosen.

The frequency and years of cell phone use, as well as the applications used, are influenced by the perceptions that older people have about cell phone use. In addition, it was found that age, gender and socio-educational level determine the perceptions that older people have about cell phone use.

This research has implications for interventions aimed at improving older people’s functional health. Understanding the perceptions of older people in relation to technology will enable the enhancement of its utility to foster an autonomous lifestyle and social integration in old age.

The purpose of this paper is to draw on concepts from the creative economy literature to present a proposal for conceptualizing the creative industries from the perspective of the ideas underlying the concepts of industrial districts and the triple helix. The analysis lays out the foundations with a review of the literature on the creative economy and builds upon them with the terminology of creative industries and industrial districts.

The analysis lays out the foundations with a review of the literature on the creative economy and builds upon them with the terminology of creative industries and industrial districts. A three-dimensional representation is developed, from a perspective in which the three dimensions comprise university, creative industries and government, combined with seven underlying factors that define the archetypal framework from the perspective of the creative economy of the region's handcrafts.

Working from the principal of an analysis of underlying factors, the paper presents an ethnographic study of the potentials and obstacles present in the handcrafts sector and delineates the work that remains to be done to enable construction of a creative economy.

A prominent possibility based on the ethnographic study of the potentials listed, the creative economy of the handicraft sector is underexplored in the Amazon. Based on the Amazon heritage of the people in the Alto Solimões region, future prospects such as establishment of guilds, clusters and internationalization of production in a tourism association represent sui generis potentials for the economic development of the Alto Solimões region of the Brazilian Amazon.

The purpose of this study was to review the information on the scientific efforts and achievements in sustainable industrial textile applications of natural colourants. Then the paper suggests the ways of improving the industrial textile applications of plant-based colourants.

The literature on the chemistry, sources and extraction of plant-based natural colourants was reviewed. The reviewed information was analysed and synthesised to provide techniques for selecting sustainable extraction methods, possible sustainable textile applications of natural colourants and the challenges which hinder industrial textile applications of plant-based natural colourants. The ways of overcoming the challenges of the industrial textile applications of plant natural colourants were suggested. Lastly, the current situation of industrial application of natural dyes in textiles is presented.

Despite the scientific achievement to overcome the challenges of natural colourants for textiles, the global industrial application of natural colourants is still low. Inadequate knowledge of the dyers results into poor performance of the natural dyed textile. The natural dyed textiles are expensive due to the scarcity of raw materials for manufacturing of natural colourants. The selection of suitable extraction, application methods and type of substrate should consider the chemistry of the particular colourant. The society should be educated about the benefits of natural dyed textiles. Cultivation of colourant-bearing plants should be promoted to meet the industrial material demand.

The paper provides a synthesized collection of information about the source, chemistry, extraction, textile application and challenges of plant-based natural colourants. The reviewed information was analysed and synthesised to provide techniques for selecting sustainable extraction methods, possible sustainable textile applications of natural colourants and the challenges which hinder industrial textile applications of plant-based natural colourants. The ways of overcoming the challenges of the industrial textile applications of plant natural colourants were suggested.
