Usability assessment of agrotourism farm websites in Poland

Król Karol, Zdonek Dariusz

Purpose: Interactivity and simplicity of navigation make users browse a website, and its usefulness is the main factor which influences the intention of using it to buy a product or service. The aim of the paper was to identify the most frequent project errors that negatively impact the usability of websites of agortourism farms. Design/methodology/approach: The surveys were carried out by the audit method in a set of websites which were grouped according to accepted categories. The audit was based on a heuristic analysis using a control list. Findings: A number of usability problems have been identified in the set of examined websites; however, the most important were the lack of explicit updates or the presentation of outdated information, as well as the dysfunction of forms – contact and inquiry. Zero-category sites are unusable. They are characterised, among others, by no visible updates (or presentation of outdated information), archaic technique of execution, often based on so-called “Frames” (iframes) or tables, as well as imperfect, archaic graphic design. Originality/value: The usefulness of a website (reflected in the design details) goes into the background when it only serves an information and contact function and does not provide advanced functionalities, such as, for example, an accommodation booking form. In the case of agrotourism farms, the most important elements are the thematic graphic design and exhaustive content.

Features of platinum as the carbon nanocomposites component

Purpose: The primary aim of the article is to present the methodology of selection of a noble metal for a constituent component of a Carbon NanoTubes-NanoParticles (CNT-NPs) nanocomposite. The platinum group elements, i.e. Pt, Rh, Rd, Pd, were characterised as part of the works in terms of their suitability for the planned experiments with the weighted scores method. Design/methodology/approach: A dendrological matrix was used for selection of a noble metal, thus employing a procedural benchmarking method. Findings: The heuristic investigations conducted have revealed that, considering the criteria used for the assessment of the potential and attractiveness of the analysed metals, platinum was awarded the highest weighted score for the analysed materials. Practical implications: The CNT-NPs nanocomposites fabricated by deposition of nanoparticles of noble metals onto carbon nanotubes are characterised by subtle electrical properties and a highly developed specific surface, which makes its particularly suitable as active elements of industrial gas sensors such as: H2, CO, CO2, NH3, NO2, CH4, H2S. Moreover, applications are expected of such nanocomposites in biomedicine as glucose and cholesterol sensors. Originality/value: The selection of a platinum group metal as a constituent component of a nanocomposite consisting of carbon nanotubes and nanoparticles, using the procedural benchmarking technique.
