Abstract
Discusses the performance of a simple genetic algorithm (GA) applied to a one‐dimensional inverse thermal field problem. Builds on these results by considering changes in GA performance that result from the introduction of non‐complementary crossover, stochastic remainder sampling and a combination of the two. Shows that, in comparison to the simple GA, non‐complementary cross‐over provides more rapid convergence, while stochastic remainder sampling without replacement has the opposite effect. However, when both strategies are combined, they provide considerably better performance with greater diversity within the population.

Abstract
Purpose
This study aims to empirically validate the holistic consumer-based brand equity (CBBE) framework and establishment of the cross-over effect using consumer preferences for wine “regions.”
Design/methodology/approach
The authors utilize a sample of 275 regular wine purchasers in Australia, who were aged above 30 years old and had consumed regional wine in the last 3 months through an online consumer panel survey.
Findings
By testing competing CBBE models, the main research model was found to have the greatest predictive ability, due to its inclusion of both the rational and emotional paths and the cross-over effect between consumer brand judgment and brand feeling. This paper indicates that consumers enhance brand equity and develop a strong ongoing relationship with regional wine brands by simultaneously engaging in both mental behavior paths, where, in the meantime, rational processing has a cross-over effect on emotional processing.
Originality/value
This study expands the brand management literature by answering the future research on the CBBE model identified by Hall et al. (2021). Moreover, it establishes the underexplored cross-over effect within the CBBE literature. Furthermore, it adds to the marketing and wine-marketing literature by extending the concept of the brand to other attributes in consumer choice, such as a wine region as outlined by Giacomarra et al. (2020). Thus, this study advances the existing branding knowledge in a practical sense, which enables regional wine marketers and wine retailers to undertake promotional and product development strategies accordingly.

Abstract
Purpose
One of the main risks to investors in securitized reverse mortgages is that the value of the reverse mortgage exceeds that of the property. The purpose of this paper is to develop a model that determines paths of constant cross‐over points across any pairs of interest and inflation rate.
Design/methodology/approach
To study the behavior of hyper‐surfaces, multivariate calculus was used.
Findings
Knowing that the value of a reverse mortgage increases above that of the property value once it goes beyond the cross‐over point t*, it is possible to construct a pool of reverse mortgages, such that for any pairs of inflation rate and interest rate (x, r), these reverse mortgages move along lines of constant cross‐over points t*.
Originality/value
The paper develops a model that determines paths of constant cross‐over points across any pairs of interest and inflation rate, which can be used when structuring pools of reverse mortgage‐backed securities, to credit‐enhance investors.

Abstract
It is proposed that reliable multilevel thick‐film conductor interconnect, having high track conductivity, can be fabricated with conventional air‐firing thick‐film materials, by combining the high conductivity of a pure silver conductor with the solderability of a palladium‐silver conductor. Thick‐film conductor interconnect fabricated in this manner was shown to meet comfortably the stringent requirements of a 20 year service life. A development in the standard technology used to obtain high conductivity interconnect, nitrogen‐firing copper thick‐film materials was also evaluated. It was found that new lower porosity dielectrics may allow copper thick‐film conductor interconnect to be as reliable as the air‐firing alternatives. The activation energy for the process of silver migration through a thick‐film dielectric in a humid environment was found to be in the region of 0.6 eV. The accelerating influence of humidity was also measured.

Abstract
Purpose
Most people live in cities and work in offices, two contexts offering many lifestyle-related and environmental health risks. To advance their health, this paper aims to introduce an analogy between urban design and facility design to explore whether health-directed design interventions in cities and facilities are related and to look for applicable cross-overs and opportunities to develop the facility management (FM) profession on the urban level.
Design/methodology/approach
The principles of abductive reasoning as a first phase of scientific investigation were followed, by introducing a new idea and attentively observing phenomena in the communities of FM and urban design. The method was desk research, in the context of discovery.
Findings
Many possible cross-overs exist which offer opportunities for urban planners and facility managers to reinforce each other and interesting market opportunities for the further development of urban FM. However, more systematic research is needed on efficacious and effective interventions. Furthermore, experiences and capacities of the FM sector should be unlocked and applied within a city context, as the knowledge and experiences of facility managers and urban planners can create synergy.
Practical implications
The findings are directly applicable to facility and urban design practices and to FM education by involving students in city design practices.
Originality/value
Cross-overs between facilities and cities are new and can inspire both facility managers and urban planners to work together more closely for the benefit of citizens and employees.

Abstract
Purpose
Organizational life and policy making is increasingly conceived in terms of a “three sector” model – public, private and “third”. The purpose of this research paper is to examine a little‐studied phenomenon that increasingly characterises societies in both the “developed” and the “developing” worlds. It aims to argue that these “sectors” have permeable boundaries, and that increasing numbers of activists and professionals operate across such boundaries, with important implications for policy and work.
Design/methodology/approach
The research paper reports on a set of new ethnographic life‐work history data from the UK, Bangladesh and Philippines to explore experiences of people who cross between, or straddle, the third sector and the public sector.
Findings
The paper constructs a preliminary typology of boundary crosser archetypes for purposes of further analysis. This is based on motivations and levels of boundary crossing. Boundary crossing of this kind is linked with the concept of “work role transition”, and with the micro‐politics of policy contention.
Practical implications
The paper concludes by suggesting that such work may offer new practical insights into strengthening the capacity of both third sector and government agencies.
Originality/value
The paper aims to be original in opening up this new topic for further discussion (and in particular problematizing the idea of sector boundaries), and through using the life history method to as part of organisational ethnography.

Abstract
Moving average trading strategies are examined for trading ten major currencies during the 1997‐2001 time period. Both a traditional trend‐following moving average cross over strategy and a contrarian strategy are tested. Following a simple moving average cross over out performed, on average, the contrarian strategy. However, neither strategy consistently outperformed a simple strategy of holding U.S. dollars during the four‐year test period.

Abstract
Thick film screen printing technology is able to reach a pitch of 250 μm. In an attempt to achieve lower values, two approaches have been developed so far. Both are based on the combination of screen printing as a deposition technique and photolithography for the patterning. The first approach uses photoimageable conductor and dielectric pastes; the second is based on photoimageable dielectric and etching of the fired conductor. In order to obtain a full characterisation of both processes, a test module was designed and manufactured by using the first process and identical test modules were provided by the supplier using the second technology. The design of the test module is based on a two‐layer interconnection pattern including structures for testing cross‐overs, via interconnections with various resolutions (down to 50 μm via size), in order to investigate the limits of these technologies. This paper gives a comparison of these two approaches based on the results of electrical and mechanical measurements performed on both sets of the test modules. Electrical parameters and resolution data are discussed for both processes. The chip and wire assembly method is evaluated to prequalify the technology as an advanced MCM‐C technology for telecoms applications. Finally, the results of reliability tests (humidity ageing and burn‐in) are presented.

Abstract
The paper describes the results obtained by the integration of Polymer Thick Film and Printed Circuit Technologies. Polymer Thick Film (PTF) Technology, applied to PCB manufacturing, helps the designer's task considerably and offers an interesting way to achieve time and cost reduction. The use of conductive and dielectric materials to generate cross‐overs and low interconnection density multilayers on epoxy‐glass substrates is shown and basic design rules are discussed. The performances of PTF conductive materials from two different suppliers are investigated in terms of conductivity, current carrying capacity and contact resistance with the copper‐clad layer. Surface and bulk insulation resistance, capacitance, loss factor and breakdown voltage are studied for dielectric materials from two different suppliers. The effects of environmental tests, i.e., thermal shocks, high temperature storage and temperature‐humidity‐bias test, on the performances of dielectric and conductive PTF are investigated by means of suitable test patterns. Application examples of Transmission System boards are discussed in terms of design and manufacturing times and costs.

Abstract
Purpose
The purpose of this paper is to investigate how globalised business programmes in higher education in Taiwan fills latent gaps between business education and the local job markets from viewpoints of teachers, students in higher education, and those working in the job markets within five years of graduation. The distinction in viewpoints from teachers, students, and graduates is valuable in examining how globalised business programmes in Taiwan help students in competitiveness in the local job markets.
Design/methodology/approach
Six teachers (five males, one female) in business programmes from two national universities with teaching experiences ranging from 2 to 19 years were interviewed. Ten students (four males, six females) in business programmes from six universities ranging from junior to master’s level were interviewed. Nine people (five males, four females) who were working full-time in the local job markets within five years of graduation from business programmes were interviewed. A total of 25 subjects (14 males, 11 females) participated in the study.
Findings
In course-related issues, students seem to have difficulties in understanding certain issues with different cultural background, and this affects teachers using textbooks and cases with USA or European standpoints. In applicability, some teachers believe it is students’ responsibilities to know how to apply what they have learned in school in practice. Those graduates who are working in local markets explained that in reality they do not apply much of what they have learned in globalised business programmes at work. In crossing over the gap, some teachers try to include local cases in teaching materials.
Research limitations/implications
The argument in this study is not to lose the beauty of localisation in globalisation in business programmes in higher education. The latent gaps between globalised business programmes and local job markets can be crossed over with a strong foundation of training in theories in globalised business programmes plus some experiences obtained in working experiences.
Originality/value
Findings in this study provided new insights into gaps between globalised business programmes and local job markets, and how it can be crossed over with a strong foundation of training in theories plus experiences obtained in practical training. Generic competence and transferable skills in local business operations ought to be included in globalised business programmes.
