Abstract
Purpose
Deposition of ink containing metal particles is possible using inkjet technologies. The purpose of this paper is to show a novel method for deposition of iron microparticles, with an average diameter of 1.24 μm, on a glass substrate that can potentially achieve concentrations of 0.21 per cent or higher.
Design/methodology/approach
The method combines drop‐on‐demand (DOD) technology with a creative way of positioning iron microparticles near to the nozzle's print head. The use of ferromagnetic particles allows the control of particle dispersion on the target sample surface. The particles are positioned close to the nozzle using a sharpened steel rod as holder and their alignment is controlled by generating an external magnetic field along the sharpened steel rod.
Findings
Successful deposition of iron microparticles with a potential concentration of 0.21 per cent or higher is reported.
Research limitations/implications
The implemented method is restricted to ferromagnetic particles or alloys of ferromagnetic and non‐ferromagnetic materials.
Practical implications
The method described could be integrated to control the deposition of iron microparticles in the production of optoelectronic devices and biosensors. This method speeds up the deposition process due to the higher metal microparticle concentrations achieved.
Originality/value
The deposition method introduced in the paper reached concentrations of 0.084 per cent, similar to the highest concentrations (0.1 per cent) reported with conventional methods (inkjet inks containing metal nanoparticles). It also prevents the blocking of the print head nozzles, thus improving the efficiency of Fe particle deposition.

Abstract
Despite the multitude of regional-based collaborations in higher education, regionalism theories have received relatively little attention in the literature on higher education. In view of this gap, this chapter seeks to make a case for the study of regionalism and explores how this field could enrich higher education research. This chapter discusses the context of the rise of the regional landscape vis-à-vis the acceleration of globalisation and internationalisation of higher education. It further probes into theoretical and empirical insights, elucidating in particular core regionalism concepts, theories and approaches within the more recent ‘turns’ in regionalism. Empirical cases from regions across the world are presented to help expound on the conceptual points raised.

Abstract
We focus our study on children of immigrants in science, technology, math, and engineering (STEM) fields because children of immigrants represent a diverse pool of future talent in those fields. We posit that children of immigrants may have a higher propensity to prepare for entering STEM fields, and our analysis finds some evidence to support this conjecture. Using the National Education Longitudinal Study (NELS: 88-00) and its restricted postsecondary transcript data, we examine three key milestones in the STEM pipeline: (1) highest math course taken during high school, (2) initial college major in STEM, and (3) bachelor’s degree attainment in STEM. Using individual level NELS data and country-level information from UNESCO and NSF, we find that children of immigrants of various countries of origin, with the exception of Mexicans, are more likely than children of natives to take higher-level math courses during high school. Asian and white children of immigrants are more likely to complete STEM degrees than third-generation whites. Drawing on theories of immigrant incorporation and cultural capital, we discuss the rationales for these patterns and the policy implications of these findings.

Abstract
Taking as reference a sample of around a hundred biographical materials on entrepreneurs in Mexico and Colombia, the purpose of this chapter is dual. Both to show the relevance and varied modalities that the biographical approach has enjoyed in business history research since the 1990s, and to display the intrinsic potential this modality of scholarship entails for entrepreneurship endeavors. In particular, it discusses the prospects to incorporate this body of empirical works into the large Latin American audience attending undergraduate, graduate and executive education programs in business, economic history and related fields. The chapter is organized into three sections. The first two are devoted to illustrate relevant patterns in the entrepreneurial trajectory of individuals and entrepreneurial families studied in each of the two countries under consideration. The last section identifies some conceptual issues that may impact current debates on Latin American business development as exemplified in recent business and economic history journal venues and scholarly conferences.

Abstract
At my retirement luncheon (July 2004), a colleague described the effect of my photography in a way that has special resonance for a discussion of campus diversity. I had recently installed three photo composites in UCLA's Ashe Student Health Center. These are collections of about 50 photographs each, presented in the form of the I Ching hexagrams for creativity, inner truthfulness, and community. Ronni Sanlo, director of UCLA's Lesbian Gay Bisexual Transgender (LGBT) Campus Resource Center, said that at a meeting of the Queer Alliance, students talked about seeing my new work in the Ashe Center. With my photos in place, they now feel welcome there. This response explains why the campus environment needs steady attention, so that the people of a college or university can recognize it as their own. Ronni's next words emphasize this need. Pointing to the bare walls of the residential commons building where we were having lunch, she said, “Look at these walls. Who's welcome here?”

Abstract
Uncertainty is one of the principal features of public administration in Colombia. Therefore, presenting a clear and consistent analysis is difficult. This uncertainty exists alongside interesting efforts to modernize institutions. Among the challenges faced by public administration in Colombia, we find corruption, illegal bands of drug traffickers, and the lack of trust between critical actors involved in governance. The aim of this chapter is to share an analysis that illustrates the difficulties and contradictions faced by those working in the public sector.

Abstract
Purpose
This systematic review of literature purposes to explore the impact of climate change on Mexico's water resources, exploring the impacts and efforts to address the problem as well as their effectiveness.
Design/methodology/approach
The researcher relied on several tools to obtain scholarly articles. The primary approach was using preferred reporting items for systematic reviews and meta-analyses. The Journal Impact Factor was an important consideration for the inclusion and exclusion criteria. The work also excluded all journals predating 2009. The work emphasized using journal articles. However, it consulted textbooks and documents from the government and water conservation sources. Contextually the sources with the highest Journal Impact Factor index were selected, paying heed to their relevance to the topic under investigation. Fifty sources out of seventy were included in the systematic review.
Findings
Mexico's already strained water resources have been negatively impacted by climate change, behooving the Mexican government to implement various mitigative strategies. However, scholars reported mixed results on the effectiveness of the various policies and programs implemented by the Mexican government. Key impediments to sustainable implementations entailed the political and social contexts surrounding the conservation policies in Mexico.
Originality/value
Numerous articles have explored the impact of climate change on Mexico's water resources, but many focus on a specific aspect. This work took a holistic approach, synthesizing multiple impacts and providing a sociological perspective on the effects, mitigation efforts, and implementation challenges.

Abstract
Purpose
The purpose of this paper is to examine the symbolic representations of non-users compared to the life experiences of users related to a luxury brand. In particular, the study examines whether product design mediates the relationship between antecedent factors of country-of-origin effect and product experience, and it also investigates the moderating effects of reference groups (non-users vs users) on the relationship between antecedent factors of country-of-origin effect and product design related to a luxury brand, namely, the Mercedes-Benz C-Class or E-Series.
Design/methodology/approach
A sample of convenience of 272 persons classified as non-users and users is investigated. An online questionnaire was used and 28 statements are included in the analysis based on a seven-point Likert scale.
Findings
The study reveals that the country-of-origin effect for the model of non-users and users has a very good fit with current data and is statistically significant. It also reveals that all relationships are significant except for price consciousness to product design and for brand familiarity to price consciousness. There is also partial mediation of product design between antecedent factors and product experience. Furthermore, the moderating effect of reference groups appears to play an important role, as it impacts the relationship between antecedent factors of the country-of-origin effect and product design/product experience.
Originality/value
This study indicates that the non-users’ group based on the hypothetical purchases of a luxury brand with a strong country image has a different country-of-origin effect to the users’ group of the same luxury brand. Moreover, the study concludes that there are statistically significant differences between the non-users’ group versus users’ group of a luxury brand (Mercedes-Benz), and these differences are concerned with the constructs of brand familiarity, brand commitment, product design and product experience. Finally, the study reveals that “price consciousness” is not relevant for luxury brands. Managerial implications, limitations of the study and future research directions are discussed.

Abstract
Purpose – Analyzing support strategies (such as childcare, elderly care, nursing, and remittances) of Ukrainian migrants living in Germany, the chapter addresses the interrelationship of social inequality and migration. First, it explores mechanisms influencing the unequal distribution of financial and care support within Ukrainian transnational families. Second, it examines how the unequal distribution influences migrants’ social mobility in Germany.
Methods – Building on the intersectionality approach the chapter indicates class, ethnic, and gender-specific categorizations as being important determinants of unequal support distribution. Conducting 28 semi-structured interviews the author used the multisited research methodology including the sending (Kiev, Rogosin near Lviv, Poltava and Ivano-Frankovsk) and the receiving (Bielefeld) localities.
Findings – The research results point out how correspondent gender narratives, self-ethnicization and migrants’ strategies of status representation structure the unequal support distribution. First, marital status regulates quantities of migrant women's support, which encourages the self-exploitation of married migrant women, in contrast to single mothers. Second, the quantities of migrant men's social support are influenced by their educational achievements in Germany. In sum, migrant men and single mothers are generally sooner integrated into the formal labor market than married migrant women.
Limitations – The interpretation of research results is limited to a number of qualitative interviews and should not be over-generalized in a quantitative manner. Nevertheless, it provides insights into how the transnationally organized reproductive sector influences migrants’ social mobility in the country of destination.
