An appropriate equivalent model is the key to the effective analysis of the system and structure in which permanent magnet takes part. At present, there are several equivalent models for calculating the interacting magnetic force between permanent magnets including magnetizing current, magnetic charge and magnetic dipole–dipole model. How to choose the most appropriate and efficient model still needs further discussion.

This paper chooses cuboid, cylindrical and spherical permanent magnets as calculating objects to investigate the detailed calculation procedures based on three equivalent models, magnetizing current, magnetic charge and magnetic dipole–dipole model. By comparing the accuracies of those models with experiment measurement, the applicability of three equivalent models for describing permanent magnets with different shapes is analyzed.

Similar calculation accuracies of the equivalent magnetizing current model and magnetic charge model are verified by comparison between simulation and experiment results. However, the magnetic dipole–dipole model can only accurately calculate for spherical magnet instead of other nonellipsoid magnets, because dipole model cannot describe the specific characteristics of magnet's shape, only sphere can be treated as the topological form of a dipole, namely a filled dot.

This work provides reference basis for choosing a proper model to calculate magnetic force in the design of electromechanical structures with permanent magnets. The applicability of different equivalent models describing permanent magnets with different shapes is discussed and the equivalence between the models is also analyzed.

This research aims to address ethnocentric consumers’ willingness to boycott dual origin brands, in the particular case of national brands linked to a very specific regional origin, through analysing the paradox of (unfavourable) regional ethnocentrism versus (favourable) consumer–brand relationship (i.e. brand identification, trust and love) on consumers’ decision to buy or boycott those brands in that circumstances. Building on social identity and cognitive dissonance theories, this study aims to examine the Spanish consumer relationship with national brands originated in Catalonia considering the current conflicting circumstances in the region.

The authors collected data by means of personal questionnaires, distributed among 277 Spanish consumers of Catalan brands of Cava. The data is analysed by using structural equation modelling and linear structural relations.

After controlling for brand familiarity, the results of this study reveal that ethnocentrism negatively distorts consumers’ confidence in dual origin brands and highlight the role of identification and trust as brand love antecedents. It also reveals that ethnocentrism has a more profound impact on boycotting decision than brand love.

This study is one of the few to capture the puzzlement created by the paradoxical nature of the brand’s duality of origin. Furthermore, it contributes to the marketing literature by examining the impact of ethnocentrism on two relationship variables (i.e. identification and trust) and exploring their joint impact on consumers’ decision to buy or boycott. The findings of this study can be helpful for companies facing boycotting behaviour triggered by ethnocentric consumer reaction towards dual origin brands.

Esta investigación tiene como objetivo abordar la disponibilidad de los consumidores etnocéntricos para boicotear las marcas de origen dual -en el caso particular de marcas nacionales vinculadas a un origen regional muy específico-, mediante el análisis de la paradoja del (desfavorable) etnocentrismo regional versus la relación (favorable) entre el consumidor y la marca (es decir, la identificación, la confianza y el amor a la marca) en la decisión de los consumidores de comprar o boicotear dichas marcas en esas circunstancias. Partiendo de las teorías de la identidad social y la disonancia cognitiva, este estudio examina la relación del consumidor español con las marcas nacionales originales de Cataluña, considerando las circunstancias conflictivas actuales en la región.

Los datos se recogieron mediante cuestionarios personales, distribuidos entre 277 consumidores españoles de marcas catalanas de Cava. Los datos se analizaron utilizando modelación de ecuaciones estructurales y relaciones estructurales lineales.

Después de controlar la familiaridad con la marca, nuestros resultados revelan que el etnocentrismo distorsiona negativamente la confianza de los consumidores en las marcas de origen dual y destaca el papel de la identificación y la confianza como antecedentes del amor por la marca. También revela que el etnocentrismo tiene un impacto más profundo en la decisión de boicotear que el amor por la marca.

Este estudio es uno de los pocos que captura la confusión creada por la naturaleza paradójica de la dualidad del origen de la marca. Además, contribuye a la literatura de marketing al examinar el impacto del etnocentrismo en dos variables relacionales (la identificación y la confianza) y explorar su impacto conjunto en la decisión de los consumidores de comprar o boicotear. Nuestros hallazgos pueden ser útiles para las empresas que se enfrentan al comportamiento de boicot provocado por la reacción etnocéntrica de los consumidores hacia las marcas de origen dual.

This paper aims to provide empirical evidence on formal stakeholder participation (or “lobbying”) in the early phase of the International Sustainability Standards Board’s (ISSB’s) standard-setting.

Drawing on a rational-choice framework, this paper conducts a content analysis of comment letters (CLs) submitted to the ISSB in response to its first two exposure drafts (published in 2022) to investigate stakeholder participation across different groups and jurisdictional origins. The analyses examine participation in terms of frequency (measured using the number of participating stakeholders) and intensity (measured using the length of CLs).

Preparers and users of sustainability reports emerge as the largest participating stakeholder groups, while the accounting/sustainability profession participates with high average intensity. Surprisingly, preparers do not outweigh users in terms of participation frequency and intensity; and large preparers outweigh smaller ones in terms of participation intensity but not participation frequency. Internationally, stakeholders from countries with a private financial accounting standard-setting system participate more frequently and intensively than others. In addition, country-level economic wealth and sustainability performance are positively associated with more participating stakeholders.

This study is of interest for organizations and stakeholders involved in or affected by standard-setting in the field of sustainability reporting. The finding of limited participation by investors and from developing countries suggests the ISSB take actions to enhance the voice of those stakeholders.

The imbalances in stakeholder participation that were found pose potential threats to an important aspect of the input legitimacy of the ISSB’s standard-setting process.

To the best of the authors’ knowledge, this paper is the first to explore stakeholder participation by means of CLs with the ISSB in terms of frequency and intensity.

National cultures significantly explain cross-country differences in the relation between asset growth and stock returns. Motivated by the notion that managers in individualistic and low uncertainty-avoiding cultures have a higher tendency to overinvest, this study aims to show that the negative relation between asset growth and stock returns is stronger in countries with such cultural features. Once the researchers control for cultural dimensions, proxies associated with the q-theory, limits-to-arbitrage, corporate governance, investor protection and accounting quality provide no incremental power for the relation between asset growth and stock returns across countries. Evidence of this study highlights the importance of the overinvestment hypothesis in explaining the asset growth anomaly around the world.

This paper aims to interpret the multidimensional Asian American identity of immigrant Indians in terms of pan-ethnicity, gender and religion.

The social construction and experience of race in the US and the intersection of multiethnic Asian American identity with race, gender and religion will be used in critically commenting on the interview of primary ethnic identity of Indian Americans including the pan-ethnic identity of Indians in the US as Asian Americans, the Mar Thoma Church community, the second-generation Patel family's union formation in terms of gender identity.

The future directives include Asian American Movement (AAM) which is trying to incorporate Indians as pan-ethnic identity assimilation and the process of holding American identity as primary identification of Indians.

Policy recommendations are that the US Census Bureau should include Indian Americans as separate ethnic identity for Indian immigrants like the Chinese Americans. USCIS (US Citizenship and Immigration Services) should reform policies to include the wives of H-4 visa holders. The Department of Homeland Security (DHS) should provide secure living environment for Indian immigrants. The US Department of Labor should provide equal opportunities for women in their immigration policies.

This paper will critically analyze the interview results of primary ethnic identity and justify the hypotheses of Asian American identity of Indians, whether (1) they merge with the American identity as part of cultural assimilation or (2) retain their Asian identity beyond Americanized identity or (3) go beyond both American and Asian identity to restate their Indian ethnicity.

The purpose of this paper is to investigate the geographic dissemination of work in International Business (IB) by investigating the extent to which research topics tend to see mostly local use – with authors from the same geographic region as the article identified by the topic model as the first article in JIBS building on the topic – vs global use – where topics are used by authors across the world.

Topic modeling is applied to all articles published in the Journal of International Business Studies between 1970 and 2015. The identified topics are traced from introduction until the end of the sampling period using negative binomial regression. These analyses are supplemented by comparing patterns over time.

The analyses show strong path dependency between the geographic origin of topics and their spread across the world. This suggests the existence of geographically narrow mental maps in the field, which the authors find have remained constant in North America, widened yet are still present in East Asia, and disappeared in Europe and other regions of the world over time. These results contribute to the study of globalization in the field of IB, and suggest that neither a true globalization nor North American hegemony has occurred in recent decades.

The application of topic modeling allows investigation of deeper cognitive structures and patterns underpinning the field, as compared to alternative methodologies.

Both governments and the food industry are interested in plant-based products. New products are advertised as climate-friendly, with plant-based materials increasingly replacing animal-based content. In Finland, oat milk dominates the plant-based milk market. The authors studied what features young and urban users of plant-based and cow's milk value in oat milk for coffee and how the preferences of the users relate to ethical food-choice motives.

In total, 308 students filled in an e-questionnaire. The survey used best-worst scaling (BWS), a discrete choice approach, to measure the perceived values related to oat milk characteristics. The ethical motives were measured by a version of the Lindeman and Väänänen scale. Also the respondents' diets were asked. Preference clusters were identified and viewed with the ethical food-choice motives and diets.

The respondent group that exclusively used cow's milk attached more value to taste, added nutritional elements, discounts and recommendations by friends. The rest of the respondents attached more value to origin and sustainability-related features of oat milk. In the six-cluster solution, one extreme cluster was valuing taste and the other was valuing sustainability-related issues. All the ethical food-choice motives: ecological welfare, political values and religion were (roughly) the higher the cluster valued sustainability-related items. The respondents eating meat were more likely to belong to the clusters valuing taste than non-meat eaters that belong more likely to clusters valuing sustainability-related features.

Very few earlier studies have explored the heterogeneity of valuations of plant-based products and the products' relationship with ethical food-choice motives.

Using data for a set of 32 Sub-Saharan countries over the years 2000, 2005 and 2010, the paper investigates the effects of domestic governmental stability upon emigration and assesses whether education and gender shape the relationship.

The paper adopts instrumental variable (IV) Poisson regressions and two-stage least squares (2SLS) as robustness tests.

The paper suggests that increased governmental stability has a larger impact on the emigration of high-skilled individuals. Nevertheless, once emigrants are partitioned according to both education and gender, the authors find evidence of a larger impact of stability on the emigration of highly educated females.

The empirical findings may lack generalizability because of the chosen research approach. Then, researchers are encouraged to test the proposed propositions further.

The paper includes implications that can be drawn for both the growth and the development of Sub-Saharan Africa.

This paper fulfills an identified need to study how both education and gender shape the relationship between domestic governmental stability and emigration.

Following the standard practice of using nutrition claims to denote food functionality, this study empirically explores Chinese consumers’ willingness-to-pay for functional processed meat products by using three nutrition claims (namely “increased calcium,” “containing omega-3”, and “reduced salt”) made on pork sausages. It also aims to outline the typical characteristics of Chinese consumer segments based on preferences.

A choice-based choice experiment is utilized to investigate Chinese consumers’ valuation on attributes of interest regarding functional sausage products. First-hand data was collected in the two cities of Xi'an and Beijing.

There are market potentials for domestic and/or imported functional processed meat products among Chinese consumers. Nutrition claims made on pork sausages are appealing to Chinese consumers, and therefore, monetarily rewarded by them. Being imported from a more developed country of origin could both positively and negatively impact consumers’ WTP for nutrition claims made on pork sausages. Furthermore, specific functional modification strategies should be taken into account when addressing different segments of the Chinese market. In addition, regional impacts between Xi'an and Beijing are implied in terms of consumers’ valuation for functional pork sausages.

Limitations in the current study are mainly two folds. First, the WTP estimation magnitudes are subject to a hypothetical bias by using a stated preference approach. Second, this study only focuses on pork sausages to explore consumers’ perceptions and selects three nutrition claims among many other relevant options.

Implications are provided for meat marketers and for Chinese official food policymakers, such that promoting meat products with a nutrition claim is an attractive marketing strategy for foreign food manufacturers in China, and more reformulated meat products with better nutritional compositions should be allowed in the Chinese market.

To the best of the author’s knowledge, this research is the first to fill in the literature blank on investigating the consumers’ valuation for functional meat in the emerging market of China. Because when taking Chinese consumers as a target market and evaluating their perceptions of food quality-related labeling and certifications, the existing literature is mainly limited to topics of product safety, organic/green products, and geographical origins. However, nutrition claims, as marketable credence attributes that associate closely to the main characteristics of the functional food products, have been explored to a much lesser extent among Chinese consumers.

The purpose of this paper was identification and empirical assessment of the differentiation of consumers' attitudes in Ukraine and Poland to Russian brands and other brands offered on the Russian market after Russia’s aggression against Ukraine on February 24, 2022.

The main research methods include a systematic literature review and the authors' own surveys conducted in November 2022. The research sample comprised 950 consumers – 67% of them were Poles, 30% – Ukrainians and 3% from other countries.

A respondents' country (Poland and Ukraine) does not impact attitudes to brands offered on the Russian market after Russia's invasion of Ukraine on February 24, 2022. Moreover, it does not affect and differentiate emotional engagement in the conflict and assistance to war victims. Cluster analysis resulted in identifying two groups on the basis of consumers' declared emotional reactions to the war. The first group was smaller (N = 353, 37.2%), referred to as “indifferent consumers”, and was characterized by a greater inclination to purchase brands offered in Russia. The other cluster, referred to as “sensitive consumers” (N = 597, 62.8%), comprises those engaged in offering assistance to war victims, showing strong emotions in connection with the aggression and military activities and characterized by a clearly negative attitude to Russian and other offered brands and an inclination to boycott these brands.

A short time horizon, the study confined to two countries, difficulties in reaching Ukrainian respondents due to power failures in Ukraine in the period of conducting the survey (November 2022), a non-representative research sample – overrepresentation of people aged 18–25 years.

The research study contributes to the knowledge about consumer brand attitudes and preferences under unique social, economic and market conditions. These conditions were created by Russia's invasion of Ukraine in 2022, as well as the international and global character of the war in Ukraine. The significant implications of the study refer to brand communication policies and companies' CSR-related declarations. A number of consumers' errors were recorded, resulting from wrong brand retrieval, which were rectified at a later stage as a result of international restrictions imposed on Russia, harsh media criticism and social international embargoes imposed on brands offered in Russia. The marketing communication of contemporary global brands should give consideration to the informative function of CSR activities, and the communication process should be continuous. Critical attitudes and an inclination to boycott brands point to the possible consequences faced by inconsistent and ethically doubtful brand policies. This implication is clearly confirmed by the results of the study.

The authors also wish to highlight the implications for practice and society. As mentioned earlier, Polish consumers involved in providing aid to victims of the war also expressed their opposition to the war by boycotting Russian products and international brands remaining in Russia. Popularization of the research results obtained by the authors can be a form of sensitizing the public to the need for long-term relief, awakening global awareness of the essence and importance of sanctions imposed on Russia, as well as the possibility of expressing opposition through individual purchasing decisions and boycotting brands still present in Russia.

The study allowed for identifying consumers' differentiated brand attitudes in two countries: a country inflicted by war (Ukraine) and a front-line country, strongly supporting Ukraine (Poland). The research contributes to consumer behavior theories and studies of consumer attitudes and preferences from the perspective of international corporations' CSR activities under the unique conditions of war. Also, it contributes to the knowledge of the mechanism of forming attitudes to Russian and international brands offered in Russia among CEE consumers.
