Abstract

Purpose

This paper aims to present the development of prediction models for aircraft actuator failure impact on flight envelope within the artificial immune system (AIS) paradigm.

Design/methodology/approach

Simplified algorithms are developed for estimating ranges of flight envelope-relevant variables using an AIS in conjunction with the hierarchical multi-self strategy. The AIS is a new computational paradigm mimicking mechanisms of its biological counterpart for health management of complex systems. The hierarchical multi-self strategy consists of building the AIS as a collection of low-dimensional projections replacing the hyperspace of the self to avoid numerical and conceptual issues related to the high dimensionality of the problem.

Findings

The proposed methodology demonstrates the capability of the AIS to not only detect and identify abnormal conditions (ACs) of the aircraft subsystem but also evaluate their impact and consequences.

Research limitations/implications

The prediction of altered ranges of relevant variables at post-failure conditions requires failure-specific algorithms to correlate with the characteristics and dimensionality of self-projections. Future investigations are expected to expand the types of subsystems that are affected and the nature of the ACs targeted.

Practical implications

It is expected that the proposed methodology will facilitate the design of on-board augmentation systems to increase aircraft survivability and improve operation safety.

Originality/value

The AIS paradigm is extended to AC evaluation as part of an integrated and comprehensive health management process system, also including AC detection, identification and accommodation.

Abstract

Purpose

This paper aims to describe the design, development and flight-simulation testing of an artificial immune-system-based approach for accommodation of different aircraft sub-system failures/damages.

Design/methodology/approach

The approach is based on building an artificial memory, which represents self- (nominal conditions) and non-self (abnormal conditions) within the artificial immune system paradigm. Self- and non-self are structured as a set of memory cells consisting of measurement strings, over pre-defined time windows. Each string is a set of features values at each sample time of the flight. The accommodation algorithm is based on the cell in the memory that is the most similar to the in-coming measurement. Once the best match is found, control commands corresponding to this match are extracted from the memory and used for control purposes.

Findings

The results demonstrate the possibility of extracting pilot compensatory commands from the self/non-self structure and capability of the artificial-immune-system-based scheme to accommodate an actuator malfunction, maintain control and complete the task.

Research limitations/implications

This paper concentrates on investigation of the possibility of extracting compensatory pilot commands. This is a preliminary step toward a more comprehensive solution to the aircraft abnormal condition accommodation problem.

Practical implications

The results demonstrate the effectiveness of the proposed approach using a motion-based flight simulator for actuator and sensor failures.

Originality/value

This research effort is focused on investigating the use of the artificial immune system paradigm for control purposes based on a novel methodology.

Abstract

Purpose

Information and communications technologies (ICTs) have transformed the lives of many people around the world, yet billions remain unconnected. While many initiatives attempt to “connect the unconnected,” initiatives focused on access and skills-development alone will still fall short. Based on the authors’ experience with the SolarSPELL initiative, this study aims to propose using the concept of socio-technical awareness as a step forward in conceptualizing a more accurate picture of capabilities necessary to enable people to make meaningful use of the internet.

Design/methodology/approach

This paper uses an integrative literature review for the ideas related to the digital divide, digital inclusion and digital literacies, as well as the applied work of the authors in the SolarSPELL initiative, to develop the concept of socio-technical awareness, which is presented as a method for understanding empowered, meaningful internet use.

Findings

The argument is made that access, skills- and literacy-development are necessary but insufficient conditions for meaningful ICTs use. Accordingly, a third concept, socio-technical awareness, is introduced, and the case is made for including this concept in both application and measurement of meaningful use of ICTs.

Practical implications

The design of digital inclusion initiatives should focus on increasing socio-technical awareness to empower users to make meaningful use of digital technologies.

Originality/value

Taking a step further than most assessments of the digital divide or digital inclusion, this study proposes that to achieve meaningful internet use, people need access, requisite skills development and socio-technical awareness, to be able to make informed, empowered decisions about ICT use.

Abstract

This paper explores the sociological, economic, and political reasons for the collapse of Venezuela's 40-year “pacted” democracy, the eight-year conflict between the country's new president and the opposition, where this conflict has led Venezuela, and what its prospects are for the near future. It proposes that the collapse of Venezuela's “ancien regime” can best be understood by an examination of the impact the rise and fall of oil prices had on its economy, society, and polity. A 20-year economic decline led to the election of Hugo Chavez, a radical outsider, who refused to play along with the country's old political class. This class, in turn, refused to accept Chavez as the legitimately elected president and launched the country on an eight-year roller-coaster ride of counter-revolution and radicalization, which recently ended with the reelection of Chavez and a massive popular endorsement for the establishment of “21st century socialism” in Venezuela. Exactly what such a project means is still unclear, but it so far involves state support for self-managed workplaces and an anti-capitalist and participatory democratic state in the midst of a still functioning capitalist economy. With the apparent defeat of obstacles that are external to the Bolivarian movement, as the pro-Chavez movement is called, such as the domestic opposition and U.S. intervention, the movement is now forced to confront its internal obstacles, such as clientelism, corruption, and personalism, if it is to succeed in the long run.

Abstract

Purpose

The purpose of this paper is to compile and explain the mobile services developed by the Rector Gabriel Ferraté Library (BRGF) of the Technical University of Catalonia (UPC), in Barcelona, Spain. From a larger amount of technological features that distinguish the BRGF, only those with a main mobile component are grouped here.

Design/methodology/approach

A case study perspective is used to give a detailed picture of the mobile services and features offered by the library in both the university and the Spanish technological contexts. The paper aims to show the effectiveness and potential to deliver library services through the preferred tools of a new generation of students.

Findings

Offering mobile services has amplified the use of the library in different ways and has improved the image of the library as a technological reference for users and librarians. From a general point of view, being ahead of the game has been revealed to be an appropriate strategy for the library when implementing new technological services.

Originality/value

The paper will be useful for libraries searching new and innovative technological channels to communicate and deliver their services. So far, there have been very few papers about mobile services in European libraries and very few Spanish libraries with a significant number of these services for their users.

Abstract

More than 20 songs by Spanish and non-Spanish bands about the Castilian lord and epic hero Rodrigo Díaz de Vivar, El Cid, account for the topicality of the Hispanic Middle Ages in heavy metal. This chapter explores how diversely El Cid is addressed in 10 of these songs, in particular, from the perspectives of reception theory and both the cultural background of the band (Spanish or non-Spanish) and the language in which the lyrics are written (Spanish or English). Through detailed textual analysis and contextualisation, I will examine how, for Spanish (and Spanish-American) bands, El Cid serves the purpose of naturalising the stereotypical heavy-metal medieval knight, thereby functioning as a vindication of Hispanic cultural heritage within what is perceived to be an Anglo-American (and Germanic-Nordic) dominated musical scene. By contrast, non-Spanish bands resort primarily to El Cid to refresh the overused motif of the medieval knight, but sometimes in a more connoted manner as well, in which his iconic value as a Moor-slayer and a defender of the Western white Christian principles is highlighted. Moreover, I will discuss the appropriation and re-appropriation of El Cid by, respectively, non-Spanish and Spanish heavy metal bands, from the point of view of cultural appreciation and appropriation, and Islamophobia.

Abstract

Purpose

The purpose of this paper is to understand the perception of the bankers towards an integrated approach to corporate social responsibility (CSR) initiatives in a strategic way of achieving sustainable growth of the banking sector. The paper additionally provides insights into different CSR initiatives and their implementation process in the context of scheduled commercial banks (SCB) of India.

Design/methodology/approach

The study is exploratory and endorses the qualitative approach of primary research methodology by adopting a non-random stratified sampling method. The localist approach of the face-to-face interview has been applied to collect the data from 26 elite class respondents from 13 SCBs. The interview method was semi-structured and open-ended. The conformity, trustworthiness, credibility, transferability, dependability test of the study have ensured the quality of the data.

Findings

The study reveals that the bankers perceive CSR as a moral obligation for the benefit of the society, beyond the regular banking operations. Further, the study comprehends that the CSR initiatives play a vital role in establishing the bank's image, brand and reputation, as well as, building a strong bond of trust among the employees and the bank management. Besides, CSR activities facilitate to cultivate a better culture by improvising in the quality of customer service for achieving competitive advantages.

Research limitations/implications

The findings of the study represent a significant contribution to CSR theory from the interface of banking and society. Significantly, the results confirm that CSR initiatives play a vital role in building trust and minimise the gap between the employees and the management of the bank. The banks can increase its acceptance in the society and achieve competitive advantage by integrating CSR objectives with the business objectives to strengthen the corporate personality and brand.

Practical implications

The study will help practitioners to develop the social identity of their firm to achieve competitive advantages in long-run. The bankers can channelise their limited resources while planning, designing and the implementation of different CSR activities with the overall goal of the bank in a cost-effective way. The study is confined only to public and private SCBs and limited to the geographical scope of one state in India. Therefore, further exploration may be carried out by considering other banks and geographic regions in India and different cross-cultural settings.

Originality/value

The originality of the study lies with the in-depth analysis and quality check of the data. The results can contribute significant value to the qualitative method of conducting research.

Abstract

Purpose

The present study aims to explore the influence of green marketing functions (green activities, corporate communication of green activities and green image) on corporate image in the hospitality sector. Further, the study tries to explore the consumer’s intention to visit the hotels practicing green marketing.

Design/methodology/approach

Using snowball sampling approach, a total of 220 usable responses were obtained from the consumer via an internet survey. Data were analyzed using structural equation modeling to evaluate the strength of relationship and model fit.

Findings

The findings show that green/eco-friendly activities and green image significantly influence the corporate image of the hotel, which in turn results into significant positive impact over consumer’s intention to visit the hotel. No significant influence of corporate communication of green activities on corporate image of the hotels was found, which may be because of the low level of communication of green practices by the hotels in India.

Practical implications

The findings offer insight to the managers regarding the impact of green marketing practices adopted by the hotels on their corporate image which in turn results into increased visit/revisit intention.

Originality/value

The study deals with the topic “the influence of green marketing on corporate image”, which has received scant attention by researchers. The paper attempts to provide empirical evidence in this area. The study yields several implications that can be helpful for managers while devising green marketing strategies for the hospitality sector. The study is among the initial studies exploring the influence of green marketing on corporate image in the Indian context.
