The purpose of this paper is to show that the computation of time-periodic signals for coupled antenna-circuit problems can be substantially accelerated by means of the single shooting method. This allows an efficient analysis of nonlinearly loaded coupled loop antennas for near field communication (NFC) applications.

For the modelling of electrically small coupled field-circuit problems, the partial element equivalent circuit (PEEC) method shows to be very efficient. For analysing the circuit-like description of the coupled problem, this paper developed a generalised modified nodal analysis (MNA) and applied it to specific NFC problems.

It is shown that the periodic steady state (PSS) solution of the resulting differential-algebraic system can be computed very time efficiently by the single shooting method. A speedup of roughly 114 to conventional transient approaches can be achieved.

The proposed approach appears to be an efficient alternative for the computation of time PSS solutions for nonlinear circuit problems coupled with discretised conductive structures, where the homogeneous solution is not of interest.

The present paper explores the implementation and application of the shooting method for nonlinearly loaded coupled antenna-circuit problems based on the PEEC method and shows the efficiency of this approach.

This paper provides a framework of the indicators of the quality of text in online reviews and their influence on the perceived helpfulness of reviews. First, the authors assess the effects of concreteness, readability and credibility on review helpfulness. The authors then test whether these effects change, based on review valence and readers' personality traits (specifically, extraversion and neuroticism).

The authors conducted an online experiment in the context of hotel reviews and tested our model using Generalized Estimating Equations (GEE).

The authors' findings indicate that consumers consider all three quality features – concreteness, readability and credibility when evaluating negative reviews. However, they assess positive reviews based only on how credible they seem to be. Consumers with the personality traits of neuroticism and extraversion value different review characteristics and this difference is dependent on review valence.

To the authors' knowledge, this is the first study to examine the interactions between review valence and reader personality on review helpfulness. The authors' findings make important contributions to the literature on information diagnosticity and offer managerial implications related to customizing the presentation order of reviews based on their expected helpfulness for individuals with extraverted and neurotic personalities.

Despite the extensive body of research on absolute corporate social responsibility (CSR) performance, limited attention has been given to the distinct concepts of optimal and aggressive CSR engagement, as well as their associations with CSR awarding. This study aims to differentiate between optimal and aggressive CSR engagement and examine their relationship with CSR awarding while considering the moderating influence of board characteristics from the perspectives of stakeholder and agency theories.

This empirical analysis draws on an international dataset comprising 43,803 observations from nine sectors across 41 countries. We employ a least squares dummy variable regression approach that accounts for country, industry and year effects to conduct the analysis.

The results reveal that engagement in aggressive CSR activities beyond the optimal level leads to the generation of a social reputation through CSR awarding. However, the influence of board characteristics on this relationship is significant. Specifically, the presence of a dedicated CSR committee encourages CSR awarding in the context of aggressive CSR engagement. Conversely, board independence constrains the relationship between aggressive CSR engagement and CSR awarding. Notably, board gender diversity does not have a discernible impact on this connection.

Our evidence provides valuable insights to help firms seeking to enhance their social reputation through CSR activities better allocate their resources and avoid unnecessary financial commitments.

This study advances the current understanding by exploring the relationship between aggressive CSR engagement and the recognition of CSR awards. Furthermore, it scrutinises the factors that dictate when such aggressive CSR engagement translates into enhanced social reputation, as evidenced by the attainment of CSR awards.

This study aims to investigate whether social reputation via corporate social responsibility (CSR) awarding facilitates access to debt and decreases the cost of debt and whether governance mechanisms moderate this relationship.

The sample covers the period between 2002 and 2021, during which CSR award data were available in the Thomson Reuters Eikon/Refinitiv database. The empirical models are based on country, industry and year fixed-effects regression.

While the main findings produced an insignificant result for access to debt, they indicated strong evidence for the positive relationship between CSR awarding and the cost of debt. Moreover, the moderating effect highlights that while the sustainability committee helps CSR-awarded companies access debt more easily, independent directors help firms decrease the cost of debt via CSR awarding. Furthermore, the results differ between the US and the non-US samples, earlier and recent periods, high- and low-leverage firms and large and small firms.

For the first time, to the best of the authors’ knowledge, the authors assess whether social reputation via CSR awarding facilitates access to debt and decreases the cost of debt in an international and cross-industry sample. Little is known about the effect of social reputation on loan contracting, although social reputation conveys broader information that goes beyond the firm’s internal (performance) and external (reporting) CSR practices. The authors also draw attention to the differing roles of distinct governance mechanisms in leveraging social reputation for loan contracting.

The purpose of this study is to investigate the association between sustainability reporting (SR) and firm value considering the moderating effect of audit committee (AC) quality and auditor tenure on this association.

The data for the study comprise 41,500 firm-year observations worldwide between 2007 and 2018 drawing on ten main sectors. The authors run a country-industry-year fixed effect regression and address endogeneity concerns with further methodologies.

First, the authors find that SR is significantly and positively associated with both firm value and industry-adjusted firm value. Further tests revealed that the baseline findings hold for SR assurance and the Global Reporting Initiative framework as well. Second, the moderation analysis outlined the significant moderating role that the AC assumes. More specifically, AC independence and expertise were found to strengthen the value relevance of SR. Third, the market also appreciates the moderation of auditor tenure in SR.

Investors appreciate greater corporate transparency which means that sustainability reports are likely to reduce information asymmetry and thereby agency conflicts. In addition, the moderation analyses imply that shareholders consider AC quality while they attach value to corporate sustainability reports. Hence, the structure of the auditing function appears to perform an implicit assurance role in the value relevance of sustainability reports. In line with these implications, corporations can review and re-design their auditing function and decide whether or not they will attest to sustainability reports given that AC independence and expertise and auditor tenure predict this decision.

The study highlights the audit function’s growing role beyond financial reporting and suggests implications for ACs and auditors in ensuring shareholders about the credibility of SR.

Drawing on neo-institutional, stakeholder, social contract and contingency theories, the objective of this study is to examine whether cultural values across countries may influence decisions to assure integrated reports.

For this purpose, the authors have collected integrated reporting assurance, national culture and firm-specific data from several sources for the years ranging between 2011 and 2016 and have performed pooled and panel logistic regression analyses.

The authors found that corporations established in countries where the following characteristics prevail have higher tendencies to assure integrated reports: high collectivism among people, low power distance, strong feminine values rather than masculine values, high uncertainty avoidance, pursuance of short-term goals rather than long-term and a low level of indulgence.

The study is not free from limitations. First, the authors were only able to obtain assurance data for the years between 2011 and 2016 since 2011 was the initial year in which integrated reporting was adopted. Second, culture variables used throughout the study remained the same for each year due to the unavailability of differing data. This was noted in prior studies as well; thus, this is not an exception. Third, the assumption that all companies in a country have the same culture score is inherent in the scoring system of countries (Orij, 2010).

Based on the results, the authors drew implications for organizations, policymakers and assurance service providers. Multinational corporations can benefit from the outcome of this study by considering national cultures in formulating their corporate strategies. Finally, assurance service providers can position themselves in the marketplace by the findings of this study.

This paper aims to enhance the comprehension of corporate reporting practices by companies that operate in different countries, with necessarily varying cultural values. To the best knowledge of the authors, no prior study has yet examined the impact of national culture on the assurance of integrated reports.

This paper aims to present an interdisciplinary approach for the development and design of place brands, which goes far beyond communication strategies and advertising campaigns. The so-called “Brand-driven Identity Development of Places” (short: BIDP) approach provides a structured three-phase model that can serve as a practical guide for the development of commercial, touristy, urban and rural places.

Longitudinal collaborative action research over a time span of 20 years plus extended case study research supported the evolution of the BIDP approach.

BIDP is a circular three-phase model starting with the definition of the intended place brand identity, which in Phase 2 becomes translated into concrete touchpoint experiences along the main constituents of the place, and finally materialising into the new place format. The case study of the City of Innsbruck is prototypically used to illustrate the application of the designed approach and to report achieved results.

Place brand development based on translating socio-cultural meanings into touchpoint experiences to materialise and align place constituents is opening up new avenues to initiate and govern place development. At present, the approach is based on case studies in the western region of Austria and South Tyrol.

The three-phase model represents a practical tool for place brand managers, who want to renew and to develop their place format in a structured way. The BIDP model can be applied for all forms of places.

Foremost, the described place branding collaborations reassure the proposition of Olins (2002) and Schmidt (2007) that place branding is a crucial internal project that unites groups of people around a common strategic vision providing sense and direction besides reaching out to the traditional customer–stakeholder audience.

A structured model for brand-driven place development, which evolved during 20 years of longitudinal collaborative action research with executives and representatives of commercial, touristy, urban and rural places, BIDP locks into anthropological research findings where cultural meanings are considered as the main source for the construction of brand identities.
