The determination of electrokinetic properties such as the zeta-potential of polymer samples with classical methods is laborious and time-consuming. For this reasons, a reliable, fast, and easy to use measurement system based on streaming potential measurement was developed. In this novel measurement system, streaming potential is created by an oscillating flow of a small amount of electrolyte solution through the sample media. In addition, this setup allows direct titration and therefore time-resolved monitoring of changes in zeta-potential in a seconds timescale. With this instrument, the concentration- as well as the time-dependent adsorption behaviour of various non-ionic, anionic and cationic surfactants on a novel, regenerated cellulosic polymer was investigated. This new cellulose-based, fibrous textile polymer is permanently cationised, not only at the surface but throughout the whole fibre. The results show that even very low concentrations of surfactant, due to its charge and chemical composition, highly influence the surface charge of the polymer in a large range. Furthermore, the results for this new textile material are compared with other textile fibres, e. g. wool.

Purpose The purpose of the study is to verify the theoretical assumptions based on literature review regarding the issue of brand effectiveness evaluation and the potential measurement framework, as well as to provide insights into the nature of effectiveness measurement of city brand strategies. The findings are considered important foundations for designing a place branding measurement system, which is the next step and final purpose of the author’s research project. Design/methodology/approach A total of 12 international academic experts from eight countries (in four continents) were individually interviewed. A semi-structured individual interview was applied as a research method. Sampling was purposive and the respondents represented the fields of marketing, place branding and public management. The standardized set of 19 open-ended questions was categorized into four themes (city brand effectiveness, methodology, measurement process and indicators). Findings The measurement of effectiveness of city branding should be treated as a strategic endeavor; however, it is a complex issue where political, social and methodological challenges overlap. Barriers to the development of a well-functioning measurement system include: too narrow understanding of what brand is, lack of knowledge or culture of measurement, conflicting political interests, reluctance to involve internal stakeholders, insufficient funding and complexity of the brand itself. The reliable measurement system should be characterized by attributes such as simplicity and durability, stakeholder inclusion, political rationale, adjustment to the specificity of the city and the independence of the measuring body/institution. Originality/value Up-to-date, common standards or universal measurement frames of the place branding measurement system do not exist. No discussion can be found in the literature on how such a system should be designed and implemented. Opinions of the experts interviewed provide important insights into the components and conditions of the reliable measurement system that would meet both methodological standards and practical needs. Further studies and analyses are however necessary to eventually compose the optimal city brand measurement system.

Knowledge measurement is developing into a new research field in the area of knowledge management. To ensure that a company is successful, business, technology, and human elements must be integrated and balanced into a knowledge measurement system. The introduction of a knowledge audit with the objective to uncovering the tacit knowledge in an organization and of identifying the existing management practices is needed. This chapter uses the quantum mechanical thinking as a reference model for the development of a knowledge potential measurement system. This system is influenced by three measurement components: (1) Person-dependent variables, (2) System-dependent variables and (3) knowledge velocity. Based on several case studies conducted in small and medium-sized enterprises, a process model for the implementation of the knowledge potential framework is discussed and introduced. Future research and limitations of the model are discussed in the final part.
