Establishing the validity and measurement equivalence of core marketing concepts in the emerging market economies of Africa is a key step in assessing the transferability of modern marketing theory and managerial practice to these countries. However, measurement equivalence issues are rarely addressed in studies of marketing practices in Africa. Accordingly, this study examines the equivalence of core marketing concepts based on interviews of 459 marketing managers from Kenya, Nigeria, Japan and the USA. The results show that optimal scaling analysis of the managers’ evaluations provide more valid and meaningful assessment than that of the raw data. The managers’ evaluations of the concepts revealed amazingly similar or prototypical perceptions of marketing’s core concepts and its applicability in their organizations, despite the profound country environmental differences. It appears that the concepts fall into two cross‐national categories of applicability that permeate the industrialized and developing country categorization. Managerial and research implications are discussed.

This study aims to investigate the influence of polyepoxysuccinic acid sodium (PESA), a green antiscalant, on the nucleation, crystallization and precipitation of magnesium phosphate.

The conductivity method was used to investigate the maximum relative supersaturation of magnesium phosphate across various PESA dosages. Subsequently, a magnesium phosphate scale was prepared using the static scale inhibition method (GB/T16632-1996) and then analyzed via scanning electron microscopy.

The findings showed that PESA extends the induction period of magnesium phosphate crystallization, reduces crystal growth rate and elevates the solution’s relative supersaturation. Notably, PESA exerts a low dosage effect on inhibition of the magnesium phosphate scale, with the optimal dosage identified at 10 mL. Scanning electron microscopy revealed that PESA dispenses a dispersing effect on the magnesium phosphate scale, generating numerous concave, convex and deeper pores on the scale particles’ surface, and thereby significantly enhancing the surface area, especially when using an antiscalant with variable dosages.

This study sheds new light on the impact of PESA, a green antiscalant, on the crystallization and precipitation of magnesium phosphate, thus paving the way for the development of enhanced and eco-friendly scale inhibition strategies in future applications.

This paper aims to investigate the commonalities and asymmetries between consumer responses to different types of natural designs across countries.

Data were gathered through a survey in three European countries ranking differently in what concerns Hofstede’s (1981) uncertainty avoidance dimension (UAD). Respondents can vary strongly in the way they interpret and use rating scales, exhibiting a variety of response styles. In the analysis of consumers’ preferences for logo design, this article apply constrained dual scaling (CDS) to account for response styles in categorical data.

Results demonstrate the broad appeal of natural logo designs, suggesting that design preferences are similar within countries with different cultural orientations. However, findings indicate that cultural dimensions influence how consumers respond to different types of natural logo designs. Indeed, the positive effects of organic designs are even more salient in countries with higher UAD. Thus, when managers prepare to launch their brands in countries that exhibit more discomfort with uncertainty, they should consider incorporating organic visual identity elements into their logos to achieve the maximum positive affect.

Companies invest extensive time, research and money in generating, promoting and modifying their logos. This paper provides important implications for international brand managers aiming to build a consistent and favorable brand image. From a methodological perspective, the results come from the analysis of clean data – that is, data after applying CDS, which increases the validity of the cross-country comparison.

Segmentation is an important topic in computer vision and image processing. In this paper, we sketch a scheme for a multiscale segmentation algorithm and prove its validity on some real images. We propose an approach to the model based on MRF (Markov Random Field) as a systematic way for integrating constraints for robust image segmentation. To do that, robust features and their integration in the energy function, which directs the process, have been defined. In this approach, the image is first transformed to different scales to determine which one fits better to our purposes. Then, it is segmented into a set of disjoint regions, the adjacent graph (AG) is determined and a MRF model is defined on the corresponding AG. Robust features are incorporated to the energy function by means of clique functions and optimal segmentation is then achieved by finding a labeling configuration that minimizes the energy function using Simulated Annealing.

There is a growing interest in applying the principles of biophilic design to hotel lobbies to enhance positive user experiences. However, there is little empirical research in this area, particularly for abstract or indirect biophilic approaches. The current study analyzed the biophilic strategy of “organized complexity” (which entails structured hierarchical patterns) in a hotel lobby in relation to attention restoration outcomes.

A virtual reality approach was used to create three lobby designs, differing only in their degree of organized complexity. A between-subjects study was conducted with 91 participants, evaluating reactions to the lobby designs in terms of perceived attention restoration, perceived environmental complexity and environmental preferences.

A strong positive relationship was found between participants' perception of environmental complexity and feelings of restoration. However, no statistically significant correlation was found between restoration and the objective measures of organized complexity. This suggests that individual preferences or baseline responses may play a crucial role in the benefits associated with this aspect of biophilic design.

The findings suggest a novel possibility – that responses to organized complexity may not be universal but may instead depend on an individual’s background and personal preferences. While the study found that perceived complexity was associated with restoration, the objective features of the environment that incited these perceptions were different for different participants. This indicates that more research is needed into potentially relevant personal factors.

This paper recasts the land development problems of Williams (1991) and Quigg (1993) by explicitly dealing with the effects of scale elasticity of unit rental and unit construction cost in a real estate project. Two different diseconomies of scale constraints are imposed on the rental and cost variables. We assume a concave function for the rental variable with respect to the scale of development. Whereas, on the cost side, the diseconomies of scale effect of the variable component of the construction cost is incorporated via a elasticity of scale factor that is larger than unity. The comparative statics simulated positive relationships between the premium that keeps the option of waiting to develop alive and the volatilities of the unit rental and unit construction cost. It was also found that the cost elasticity of scale and the financing cost are factors that increase the premium of the waiting option, whereas, the rental yield factor reduces the incentive of waiting. A high rental yield tends to expedite a development project because the opportunity cost of not developing the land is high. In the case analysis involving a vacant land of 8,000 square meters at Spitafield, East London, a unit rental of £267.2 per square meter (psm) is obtained, which would breakeven a cash flows of the project when the traditional “invest now or never” assumption is made. Compared with the optimal unit rental of £677.0 psm estimated by the real option model, the traditional DCF results tend to accept the feasibility of the real estate project too early and at too low a cut‐off rental.

The purpose of this study is to evaluate the category function of the sport fandom questionnaire (SFQ), determine the optimal categorization of the SFQ and calibrate the measurement qualities of the newly modified rating scale option using Rasch analysis.

This paper relies on the Rasch analysis to validate the SFQ. A series of studies are performed based on analysis procedures for the responses from 244 (study 1) and 477 (study 2) participants.

The results revealed that the original SFQ consisting of the eight-category rating scale is flagged due to irregular observation distribution and disordering of thresholds, whereas both six-category and seven-category rating scales meet the guidelines for the optimal categorization. However, only the seven-category rating scale showed desirable model-data fit indices. Furthermore, the results of the Rasch calibration model showed that all items of the SFQ have large variability, and a person's ability level varied moderately along the continuum.

Unlike previous studies, examining the psychometric properties of the SFQ, the current study provides information about the optimal categorization and presents a novel reconstruction category in measuring individuals' sport fandom level. In measuring the level of sport fandom, the authors suggest the use of a seven-category rating scale that the current study found to exhibit reliability and construct validity.

The Analytical Hierarchy Process (AHP), a multicriteria decision support system that has been successfully applied to numerous decision-making situations, has been applied to patient assessment. The AHP was used with Timeslips™, a group storytelling program that encourages creative expression among dementia patients, to determine the optimal scale for pre and post assessment among the nine most common agitation and anxiety scales. The AHP used the six criteria identified by qualitative assessment of the nine scales: (1) validity/reliability, (2) observation period, (3) training required, (4) time to administer, (5) most appropriate administrator, and (6) accessibility/cost. The AHP indicated that the Overt Agitation & Anxiety Scale was optimal for use with Timeslips; the process and results are discussed.
