Hysteresis Losses

Purpose The thermally extended Tellinen model (Kühn et al., to appear) is here investigated and equipped with a hysteresis loss model, while preserving its simple structure. Design/methodology/approach As in the original model, these approaches are based upon phenomenal observations and measured saturation curves. The authors start with the original model and step-by-step add their extensions, such that in the end they can apply the extended model in a finite element method (FEM) simulation. During the process, care is taken to ensure that the applicability in a FEM simulation is not impaired, in terms of memory requirements and computing power. Findings In comparison to the original model, this extended model needs some further requirements and so is a little bit more limited in its application. It is in itself coherent and well defined. The authors provide an on-the-fly algorithm computation of hysteresis losses. First numerical results for a coupled field/thermal system show expected behavior. Originality/value The original model (Tellinen, 1998) does not take temperature into account. It includes a model for calculating hysteresis losses, but it differs largely from the approach presented here. The thermal extension is now also equipped with an on-the-fly method for hysteresis losses. Furthermore, the authors provide some analysis of simple, stable loops.

Purpose This paper aims to propose a type of T-shaped two-axis force sensor for measuring the forces in x- and z-axes. The developed sensor has a simple structure and can be effectively assembled into compact devices. Design/methodology/approach A T-shaped plate, with both ends fixed on a base, is used as the substrate of the sensor. Eight strain gauges are placed in the root of the plate or near the sensor head, which can construct two full Wheatstone bridges on the upper and lower surfaces of the plate. When the x- or z-axes forces are applied to the sensor head, different deformation can be generated to the strain gauges. Therefore, the two Wheatstone bridges can be constructed with a different configuration for measuring the forces in x- or z-axes, respectively. Findings A prototype was designed and constructed and experiments were carried out to test the basic performance of the sensor. It has been verified that the developed sensor could measure the x- and z-axes forces independently with a high resolution of 2.5 and 5 mN, respectively. Originality/value Only one thin plate was used in the design, the forces in x- and z-axes could be measured independently and simultaneously, which made the sensor with a simple structure and compact size. Experiments were also verified that there was no crosstalk error occurred in one axis when the force was applied to the other axis.

Purpose – The purpose of this paper is to understand how “good” HR practice is characterised in SMEs and what the drivers are for adopting this good practice. The paper also explores methods for measuring the impact of HR practice which are helpful and realistic in the context of an SME. Design/methodology/approach – The research was carried out in one SME, a bakery based in South Yorkshire. It was an action research project which utilised semi-structured interviews, participant observation on the factory floor and analysis of company documentation in the diagnosis phase. In addition, reflections on action interventions have informed the findings, together with post-project, semi-structured interviews with key actors three years after the completion of the project. Findings – The drivers of good HR practice were found to be size, market position, external “coercive networks”, presenting issues, the ideology of the managing director and the energy of an HR champion. The findings demonstrate that the impact of “good” HR practice can be best evaluated in SMEs through one-shot, cost-based metrics or more strategic qualitative measures. Originality/value – The paper develops an original model to show the relationship between the drivers, the HR practices adopted and measurable outcomes. This makes an important contribution to the debate about HRM within SMEs and it has practical value for informing the development of good HR practice in SMEs.

The Relationship

Purpose Based on the theory of planned behaviour (TPB), this paper aims to investigate the effects of residents’ place attachment (PA), subjective norms (SNs) and perceived behavioural control (PBC) on their attitudes towards behaviour (AB) and behavioural intention to support tourism (BI). This paper aims to examine whether residents’ AB mediate the relationships between BI and PA, SNs and PBC. Design/methodology/approach The results are obtained using a quantitative method based on data gathered from self-administered questionnaires completed by 406 residents of Hongcun, a Chinese traditional village. Findings The TPB is successfully used to explain Chinese traditional village residents BI. The findings extend the extant research and render the TPB more widely applicable. This study confirms that the inclusion of PA within the framework of the TPB is valid and satisfactory, demonstrating continued support for the coupling of complementary theories to explain tourism development from a resident perspective. Finally, this study extends the literature on residents’ PA and demonstrates its impact on their attitudes and consequent reactions, thus supplementing the limited evidence on PA as a direct predictor of residents’ BI. Specifically, SNs are the critical factor affecting residents’ AB and their BI. Residents’ AB only mediate the relationship between SNs and their BI. Research limitations/implications This paper only includes PA within the framework of the TPB. More constructs should be incorporated to deepen the understanding of residents’ BI. In addition, the data were only collected in a traditional village. Originality/value This paper is one of the first studies to combine PA with the TPB in research on residents’ BI in a developing country – in this instance, China.

Purpose – The purpose of this paper is to explore how social need, social influence and convenience affect dependence on smartphones and purchasing behavior among university students in Pakistan’s emerging economy. Design/methodology/approach – Survey methods and non-probability purposive sampling were used to collect data from 337 respondents, and structural equation modeling was used to test the hypothesis. Findings – Overall the results provided evidence that social need, social influence and convenience significantly affect students’ dependence on their smartphones. A significant relationship also existed between students’ dependence on smartphones and their purchasing behavior. Originality/value – The availability of 3G/4G mobile networks and the growth in smartphones’ computing power have meant that this form of mobile technology is in great demand. This study provides an exclusive viewpoint concerning students’ dependence on smartphones and the effect of this on their purchasing behavior, which is a subject that has not been covered previously in the Pakistani context.

Rational Addiction Model

Purpose The purpose of this paper is to show how the taxation effect on cross-state smuggling can be a valid instrumental variable for lagged and future consumption together with the local price series. Design/methodology/approach On the same grounds, the authors raise the question using the rational-addiction model by noticing that the neighboring price differentials really capture the possible smuggling or bootlegging effects. Findings Moreover, the authors look into the extended model to test the key condition that the expected future financial consequences will affect the current consumptions. Originality/value This supports the rational-addiction model, which can be used to plan the taxation for the forward-looking consumptions.

Activity Information

PurposeThis research examines the likelihood that Panamanian and Colombian banks listed on their respective stock exchanges voluntarily disclose intangible liabilities based on such variables as their size, profitability, indebtedness, age and growth. The presented findings concur with agency theory, signalling theory and the owner-cost theory.Design/methodology/approachThe authors propose a probabilistic model to test the influence of size, profitability, indebtedness, age and growth on the disclosure of intangible liabilities. The dependent variable, the disclosure index, was constructed from a dichotomous approach using Harvey and Lusch's (1999) model, which has 24 characteristics, plus six that we added in our research. These were grouped into four categories: procedures, human activity, information and organisational structure.FindingsBanks in Panama and Colombia with a larger size, higher profitability, lower age and higher growth are more likely to disclose more information about their intangible liabilities. However, indebtedness does not serve as a determinant of the disclosure of these liabilities, even though its relationship is negative.Research limitations/implicationsThe limitation of the research was the voluntary disclosure of information about these liabilities on firms' websites.Practical implicationsThe contributions of this research are as follows. First, we used an intangible asset disclosure methodology to verify the disclosure of intangible liabilities, in line with Harvey and Lusch's model, as well as providing another six indicators, thereby producing an extended model. Second, being the first empirical research to study the disclosure of intangible liabilities in Panama and Colombia opens a door to future research on this topic.Social implicationsThis research provides a significant practical contribution to society because banks listed on public stock markets, understanding that undisclosed intangible liabilities lead to opportunity costs in their profitability, might tend to disclose more information, thus promoting greater transparency in the market.Originality/valueThe main contribution of this research is applying an intangible asset disclosure methodology to the disclosure of intangible liabilities, following Harvey and Lusch's (1999) model, as well as the creation of an expanded model.

Purpose The paper aims to develop a microcredit evaluation model (MEM) which could serve as a useful tool for banks and NBFIs when SMEs’ economic and financial risks are evaluated. Design/methodology/approach Based on the literature review, a set of 17 qualitative and quantitative prudential indicators is selected. Further, a calculation system is developed which relies on the multiple criteria analysis model elaborated by Altman (1968); starting from this, a matrix is developed and a rating system is built. The model is tested among six NBFIs which operate on the Romanian market; three of them are labeled by the Romanian Central Bank as the worst performers, while the other ones are qualified as the best performers. Data are collected from companies’ annual reports and also from the Ministry of Finance. Findings It proves that the MEM can serve as a useful tool for the national and international NBFIs’ risk assessment. It can anticipate NBFIs’ success or fall. Furthermore, its results can be guaranteed with a probability of 95 per cent, calculated through the VaR method. Last but not least, it can also be used by the international NBFIs which intend to enter in the Romanian market. Originality/value The present paper proposes an original model based on both quantitative and qualitative indicators organized in an integrative equation. The MEM helps both parties involved in the financial grant awarding process – NBFIs are able to better assess requests from SMEs, enabling them to increase the volume of granting, whereas SMEs are able to access money for development projects more easily.

Purpose The purpose of this paper is to investigate how individuals perceive and react to the involuntary demotion of a co-worker in their organisation. Design/methodology/approach The authors draw on 46 semi-structured in-depth interviews (23 dyads) with co-workers of demoted individuals. Findings The findings suggest that an individual’s observation of the demotion of a co-worker has three stages: their perception of fairness, their emotional reaction and their behavioural reaction. The perception of fairness concerned issues of distributive, procedural, interpersonal and informational justice. The emotional responses identified were feelings of disappointment/disillusion, uncertainty, vulnerability and anger. Finally, the behavioural reactions triggered by their emotional responses included expressions of voice, loyalty, exit and adaptation. Originality/value Perceptions of (in)justice perpetrated on others stimulate emotional and behavioural responses, which impacts organisational functioning. Managers should therefore pay attention to the way a demotion is perceived, not only by those directly concerned, but also by co-workers as observers.

Purpose The purpose of this paper is to understand in-depth how consumers create value in their lives using WhatsApp, the leading mobile instant messaging (MIM) application. Design/methodology/approach The study adopts the perspective of customer-dominant logic (CDL) and uses a qualitative multimethod design involving 3 focus groups and 25 subsequent in-depth interviews. The research setting was Ecuador, a Latin American country. Findings Analysis and interpretation of the participants’ stories made it possible to identify and understand the creation of four types of value: maintaining and strengthening relationships; improving role performance; emotional support; and entertainment and fun. In addition, the present study proposes a conceptual model of consumer value creation as it applies to MIM. Practical implications Understanding the way consumers create value in their lives using MIM is important not only for organizations that offer MIM applications, but also for those companies that develop other applications for mobile phones or for those who wish to use MIM as an electronic word-of-mouth vehicle. Originality/value The current study is one of the first to address the topic of consumer behavior in the use of technologies from the perspective of CDL; this perspective enables an integrated qualitative vision of value creation in which the consumer is the protagonist.
