Abstract

Purpose

The purpose of this paper is to design and test effective indoor navigation solutions for visually impaired people in situations where GPS, bluetooth or Wi-Fi signals are unavailable. The authors use the inertial measurement units (IMU), the compass and the barometer of a smart phone.

Design/methodology/approach

The authors have used commercial Android smart phones with IMU, compass and barometer to record a path and to give navigation instructions in an adapted way using a mobility-specific vocabulary. The method proposed is to save paths taking into account different indoor waypoints such as the stairs (change from one floor to another) and the change of direction of the trajectory of the path (e.g. one-fourth turn right or left), recording data from the IMU sensor’s, compass and barometer of the smart phone. Having this information and the characteristics of the each segment (distance, azimuth to the north and pressure) of the path, it is possible to provide functional navigation guidance to the visually impaired subject. Three different visually impaired people (one partially sighted and two fully blind) and three sighted people have tested the paths. The efficiency of the navigation is analyzed in terms of distance and time using the comparison between blind and sighted people.

Findings

The main finding is that it is possible to guide visually impaired people some hundreds of meters just using the sensors of a smart phone under certain conditions: the visually impaired person has to understand the guidance instructions and respect some strategies (e.g. not to walk diagonally across vast spaces). Additionally it is observed that the visually impaired participants walked distances, which are not much different to the optimal values. On the other hand; because of their hesitations using their white cane to find free paths, they take in some cases 50 percent more time to arrive (for a few minutes path, this time is not critical and even more efficient than looking for a guide). One thing to highlight is that even with this hesitation, the subjects arrived to the final destination.

Originality/value

This paper demonstrates how an IMU coupled to a compass and a barometer from a Smart Phone employing a spoken mobility language (e.g. next corridor to the left; at the end of the stairs turn right, turn left, etc.) can guide visually impaired people inside buildings.

Abstract

Purpose

The purpose of this paper is to investigate the vital determinants on the extent of corporate social responsibility (CSR) disclosure in a US context. The selected variables are CEO duality, the presence of women in the board, greenhouse gas (GHG) emissions, emission reduction initiatives, company's risk premium, financial leverage and industry's profile.

Design/methodology/approach

The environmental, social and governance (ESG) disclosure score is used as a proxy for the extent of CSR disclosure calculated by Bloomberg. The influence of plausible variables on the ESG disclosure score and its sub-categories was examined by using the least squares dummy variable model (LSDV) incorporating 100 companies listed on Standard & Poor's 500 Index for the period 2009-2012.

Findings

The results show that the emission reduction initiatives and GHG emissions influence positively the extent of ESG score. In addition, slight differences exist concerning the determinants of different types of disclosures. Furthermore, it is illustrated that a company's industrial profile seems to have differences among the extent of the different types of disclosure.

Research limitations/implications

The sample of companies is based on the US companies incorporating only large-sized ones.

Originality/value

The study extends previous studies with the inclusion of both traditional and innovative determinants of the CSR disclosure in USA taking into account four years of corporate data. A third party rating approach was adopted in order to calculate the extent of CSR disclosure. Finally, both the shareholders’ and the investors’ attitudes in relation to CSR disclosure are presented.

Abstract

Purpose

The authors examine the determinants of ESG disclosure and differentiate between voluntary and mandatory disclosure regimes in Hong Kong.

Design/methodology/approach

The authors analyse both Bloomberg ESG scores and a disclosure index score, manually constructed according to the 2019 Hong Kong Exchange ESG Guide using regression tests.

Findings

The results indicate that the level of concentrated ownership is negatively associated with the quantity of ESG disclosure only in the voluntary disclosure period, suggesting that agency problems are alleviated when ESG reporting is mandatory. The findings also show that larger firms significantly disclose higher levels of ESG information in both voluntary and mandatory disclosure periods. Furthermore, the extent of ESG disclosure significantly increases when firms' sustainability reports are audited by Big 4 accounting firms only in the voluntary disclosure period. Finally, the control variables are significantly related to the level of ESG disclosure showing that ESG disclosure increased over time and is significantly different among industries.

Originality

The authors make contributions to the literature on non-financial disclosure in relation to ESG reporting by examining the relationship between firm characteristics and ESG disclosure in the Hong Kong context under both voluntary and mandatory disclosure regimes. This study also provides important implications for other stock markets and relevant stakeholders including preparers, users and the sustainability profession.

Abstract

The purpose of this chapter is to conduct a structured literature review to examine the relationship between entrepreneurship and emotional intelligence in academic settings as well as the current entrepreneurship pedagogy for flexible, innovative and creative graduates. One hundred and twenty-eight peer-reviewed papers were analysed based on Webster’s and Watson’s (2002) methodology. Papers classified into three topics and a content analysis was implemented to discuss about the publication year, journals, authors, frequency of keywords and research method adopted. The contribution of this chapter is twofold. It is a bibliometric study which provides a macropicture of a research field, its evolution and connections among studies, in order to be a starting point for future researchers who are already studying entrepreneurial education or entrepreneurship-related scientific areas. Also, this chapter helps academics to improve educational programmes and curriculum to increase students’ entrepreneurial intention taking into account the factors that affect it.

Abstract

The aim of this chapter is to provide a holistic overview of issues and topics regarding tourism geography in Greece: from its origins to its current situation. By following a historical tracking of tourism activities in this country and the growth of tourism geography as an academic domain at the university level, the main goal is to analyze the shift of academic research on tourism from geographical perspective, as presented in both the Greek and English language literature. The chapter concludes that there is a need for practical orientation and redefinition of typologies of tourism geographies in order to apply a more sustainable and cross-disciplinary approach in the academic discourse on Greek tourism.

Abstract

Purpose

Drawing upon a political economy approach, this article aims to analyze the transformations in the labor market within the context of contemporary capitalism, focusing on the phenomenon of financialization.

Design/methodology/approach

Financialization is defined as a distinct wealth pattern marked by a growing proportion of financial assets in capitalist wealth. Within financial markets, corporate performance is continuously assessed, in a process that disciplines management to achieve expected financial results, with consequences throughout corporate management.

Findings

We find that this phenomenon has implications for labor management, resulting in the intensification of labor processes and the adoption of insecure forms of employment, leading to the fractalization of work. These two mechanisms, added to the indebtedness of workers, constitute three elements for disciplining labor in contemporary capitalism.

Originality/value

We argue that these forms of discipline constitute a subsumption of labor to finance, resulting in an increase in labor exploitation. This formulation of the relationship between financialization and changes in the realm of labor also contributes to understanding the unrealizing potential of social free time in contemporary capitalism.

Abstract

Travel and tourism have had a long history in the Nordic countries, but research on tourism has a relatively short tradition in the region. Recently, academic interest in the Nordic tourism space has grown and diversified especially as a result of increasing numbers of academics and institutions involved with tourism geographies and studies and education in the region. The Nordic context has provided thematic focus areas for empirical studies that characterize tourism geographies in the region, with topics including nature-based tourism, utilization of wilderness areas, second-home and rural developments, impacts in peripheries, and tourism as a tool for regional development. In addition, there are emerging research themes outside of the traditional core topics, such as urban, events, and heritage tourism.

Abstract

This chapter aims to familiarize the reader with some of the important aspects of tourism geography in the German-speaking countries. It starts with a primarily historical-genetic perspective on tourism development and the theoretical traditions associated with them. The second section describes the structure of the discipline, with a focus on the institutionalization of the field in the universities including their research specialization. The chapter maintains that tourism geography plays a marginal role compared with other subdisciplines of geography, though this is reflected primarily in its institutionalization and less so in the research undertaken. The last section deals with the current challenges and future prospects in German-speaking geographies of tourism from a problem-centered perspective.

Abstract

This chapter discusses the main research interests and outputs in the various branches of geography that have influenced the study of tourism from a geographical perspective. It argues that the idiographic tradition has been transversal throughout, leading to the growing interest for tourism within the geography academic community in the last 10 years. There is a focus on the birth of specific research groups, mainly related to a constellation of new university curricula on tourism and—with few exceptions of territorial tradition—to an intermittent availability of public research funds. The chapter concludes with a more general picture of the place of tourism within the geography discipline in Italy and of evolving trends in terms of research results, dissemination, and evaluation.
