Abstract

Purpose

With the use of the grey incidence analysis (GIA), indicators such as the absolute degree of grey incidence (εij), relative degree of grey incidence (rij) or synthetic degree of grey incidence (ρij) are calculated. However, it seems that some assumptions made to calculate them are arguable, which may also have a material impact on the reliability of test results. In this paper, the authors analyse one of the indicators of the GIA, namely the relative degree of grey incidence. The aim of the article was to verify the hypothesis: in determining the relative degree of grey incidence, the method of standardisation of elements in a series significantly affects the test results.

Design/methodology/approach

To achieve the purpose of the article, the authors used the numerical simulation method and the logical analysis method (in order to draw conclusions from our tests).

Findings

It turned out that the applied method of standardising elements in series when calculating the relative degree of grey incidence significantly affects the test results. Moreover, the manner of standardisation used in the original method (which involves dividing all elements by the first element) is not the best. Much more reliable results are obtained by a standardisation that involves dividing all elements by their arithmetic mean.

Research limitations/implications

Limitations of the conducted evaluation involve in particular the limited scope of inference. This is since the obtained results referred to only one of the indicators classified into the GIA.

Originality/value

In this article, the authors have evaluated the model of GIA in which the relative degree of grey incidence is determined. As a result of the research, the authors have proposed a recommendation regarding a change in the method of standardising variables, which will contribute to obtaining more reliable results in relational tests using the grey system theory.

Abstract

Coopetition is a phenomenon characterised by the simultaneous presence of cooperation and competition within a networked relationship. The current body of literature provides real instances of coopetitive networks within the tourism sector. Conversely, many countries possess the potential to initiate new examples. This research aims to identify European countries that are externally heterogeneous but internally homogeneous and thus point out competing countries that could cooperate in the tourism sector. This study contributes to the literature on cross-border tourism coopetition from a theoretical perspective of possible cooperation among 32 competing European countries using existing secondary data from the Travel and Tourism Development Index (TTDI). The results of cluster analysis show a six-group solution. Although there are many challenges and issues, the positive outlook lies in the potential for coopetition among analysed countries, which could contribute to regional tourism growth. This study proposes several recommendations essential to cross-border tourism coopetition.

Abstract

Social entrepreneurs are leaders who aspire to build more just societies through the mechanisms of the market. The concept of social enterprise has grown increasingly popular, but it continues to be a nebulous notion. This chapter explores the meaning of social enterprise and the attributes and characteristics of social entrepreneurial leaders whose enterprises have become the vehicles of social, economic, and even political transformations. The transformative potential of social entrepreneurial leaders is illustrated with brief, but prominent, examples that are aimed to inspire further research. It is shown that social entrepreneurship is not confined to an exclusive arena, but actually flourishes in diverse sectors. It is also posited that educational institutions and organizations can promote greater interest and investment in social entrepreneurship as a progressive model for a positive social change.

Abstract

This chapter primarily aims to revisit and explore the theoretical underpinnings of social entrepreneurship and dwell into what unfolds while amalgamating the conventionally considered to be dissimilar design of business entrepreneurship and the social impact? Can the prefix “social” of social entrepreneurship transform the innate characteristics of entrepreneurship? Is social entrepreneurship an essentiality in a ground-breaking playing field in the business research to facilitate new theories and concepts or a rehash of the corporate responsibility debate? Is it just an appellation or does the underscored social label and its construct allow for new possibility to be explored into the sociality of entrepreneurship along with the new-fangled entrepreneurialism in society? The chapter attempts to decode these more germane and interwoven issues like do we have to tell apart between a capitalist entrepreneurship and a non-capitalist one? Or between pioneering and replicative entrepreneurs. Can we sanctify the political in the social spheres and who (which actors) actually sets the discourse of social needs. The chapter also tracks multiple cases in the Indian locale to determine the robust application of the concept while unpacking the Indian context of social entrepreneurship. These cases are randomly selected from assorted sectors and are wide in its sweep and scope. These cases highlight on the lived experiences, where the task is truly played out. This adds to the sensibilities of new entrepreneurs and policy framers who face the challenges.

Abstract

This chapter draws upon the leadership and work of two social entrepreneurs who believe that inclusion of community members in project/venture planning and design is key to accelerate equitable system change. The social justice leaders featured, through their actions in diverse, marginalized communities, will provide a model of leadership behaviors that utilize a repertoire of styles framed in the Connective Leadership Model™. They are system-changing champions driven by their social justice passion which requires that they provide leadership through planning and design processes to achieve equity in communities and influence policy. Short case studies will define the venture’s mission, processes, and social change outcomes with examples of the type of leadership necessary for building inclusive and equitable community-based initiatives. Their words and actions will illustrate how leaders can innovate to create system impacts not by a single intervention but through multilayered processes with a broad range of benefits – for infrastructure, education, social, economic, and environmental justice programs. The results described will emphasize the critical elements of process, the insight and power of community input and involvement, and the influential cross-sector shaping of programs and policy to achieve sustainable change. This chapter concludes with a more detailed description of the Connective Leadership Model™ and how the model enables a leader to “consciously and systematically utilize a variety of behaviors,” effectively reacting to the leadership needs of a particular situation as well as using the achieving style behaviors most valued for a community-based system change venture (Lipman-Blumen, 2000, pp. 113–114).

Abstract

Purpose

The noise measurement on magnetoresistive (MR) sensors is generally conducted by techniques including single-channel data sampling and fast Fourier transform (FFT) analysis as well as two-channel cross-correlation. The single-channel method is easy to implement and is widely used in the noise measurement on MR sensors, whereas the two-channel method can only eliminate part of the system noise. This study aims to address two key issues affecting measurement accuracy: calibration of the measurement system and the elimination of system noise.

Design/methodology/approach

The system is calibrated by using a low-noise metal film resistor in that the system noise is eliminated through power spectrum subtraction. Noise measurement and analysis are conducted for both thermal noise and detectivity of magnetic tunnel junction (MTJ) sensor.

Findings

The thermal noise measurement error is less than 2%. The detectivity of the MTJ sensor reaches 27 pT/Hz1/2 at 2 kHz.

Originality/value

This study provides a more practical solution for noise measurement and system calibration on MR sensors with a bias voltage and magnetic field.

Abstract

To date, many environmental policy discussions consider inequalities between groups (typically by comparing the average or aggregate resource use of one group to another group), but most ignore disproportionalities within groups. Disproportionality, as discussed in a small but growing body of work, refers to resource use that is highly unequal among members of the same group, and is characterized by a positively skewed distribution, where a small number of resource users create far more environmental harm than “typical” group members. Focusing on aggregated or average impacts effectively treats all members of a group as interchangeable, missing the few “outliers” that actually tend to be responsible for a large fraction of overall resource use. This chapter offers reasons why we should or should not expect disproportional production of environmental impacts (from both mathematical and sociological perspectives), looks at empirical evidence of disproportionality, and offers a framework for detecting disproportionality and assessing just how much difference the outliers make. I find that in cases where the within-group distribution of resource use is highly disproportionate (characterized by extreme outliers), targeting reduction efforts at the disproportionate polluters can offer opportunities to decrease environmental degradation substantially, at a relatively low cost.

Abstract

Purpose

This study deals with the computational simulation and inverse analysis of the cooling treatment of the hypoxic-ischemic encephalopathy in neonates. A reduced-order model is implemented for real-time monitoring of the internal body temperatures. The purpose of this study is to sequentially estimate the transient temperatures of the brain and other body regions with reduced uncertainties.

Design/methodology/approach

Pennes’ model was applied in each body element, and Fiala’s blood pool concept was used for the solution of the forward bioheat transfer problem. A state estimation problem was solved with the Sampling Importance Resampling (SIR) algorithm of the particle filter method.

Findings

The particle filter method was stable and accurate for the estimation of the internal body temperatures, even in situations involving large modeling and measurement uncertainties.

Research limitations/implications

The proposed reduced-order model was verified with the results of a high-fidelity model available in the literature. Validation of the proposed model and of the solution of the state estimation problem shall be pursued in the future.

Practical implications

The solution of the state estimation problem with the reduced-order model presented in this paper has great potential to perform as an observer of the brain temperature of neonates, for the analysis and control of the systemic cooling treatment of neonatal hypoxic-ischemic encephalopathy.

Social implications

The main treatment for hypoxic-ischemic encephalopathy in neonates is the cooling of affected regions. Accurate and fast models might allow the development of individualized protocols, as well as control strategies for the cooling treatment.

Originality/value

This paper presents the application of the SIR algorithm for the solution of a state problem during the systemic cooling of a neonate for the treatment of the hypoxic-ischemic encephalopathy.
