Abstract

Purpose

Automated driving systems (ADSs) are being developed to avoid human error and improve driving safety. However, limited focus has been given to the fallback behavior of automated vehicles, which act as a fail-safe mechanism to deal with safety issues resulting from sensor failure. Therefore, this study aims to establish a fallback control approach aimed at driving an automated vehicle to a safe parking lane under perceptive sensor malfunction.

Design/methodology/approach

Owing to an undetected area resulting from a front sensor malfunction, the proposed ADS first creates virtual vehicles to replace existing vehicles in the undetected area. Afterward, the virtual vehicles are assumed to perform the most hazardous driving behavior toward the host vehicle; an adaptive model predictive control algorithm is then presented to optimize the control task during the fallback procedure, avoiding potential collisions with surrounding vehicles. This fallback approach was tested in typical cases related to car-following and lane changes.

Findings

It is confirmed that the host vehicle avoid collision with the surrounding vehicles during the fallback procedure, revealing that the proposed method is effective for the test scenarios.

Originality/value

This study presents a model for the path-planning problem regarding an automated vehicle under perceptive sensor failure, and it proposes an original path-planning approach based on virtual vehicle scheme to improve the safety of an automated vehicle during a fallback procedure. This proposal gives a different view on the fallback safety problem from the normal strategy, in which the mode is switched to manual if a driver is available or the vehicle is instantly stopped.

Abstract

Purpose

Increasing demand on rail transport speeds up the introduction of new technical systems to optimize the rail traffic and increase competitiveness. Remote control of trains is seen as a potential layer of resilience in railway operations. It allows for operating and controlling automated trains and communicating and coordinating with other stakeholders of the railway system. This paper aims to present the first results of a multi-phased simulator study on the development and optimization of remote train driving concepts from the operators’ point of view.

Design/methodology/approach

The presented concept was developed by benchmarking good practices. Two phases of iterative user tests were conducted to evaluate the user experience and preferences of the developed human-machine-interface concept. Basic training requirements were identified and evaluated.

Findings

Results indicate positive feedback on the overall system as a fallback solution. HMI elicited positive emotions regarding pleasure and dominance, but low arousal levels. Train drivers had more conservative views on the system compared to signalers and students. The training activities achieved increased awareness and understanding of the system for future operators. Inclusion of potential users in the development of future systems has the potential to improve user acceptance. The iterative user experiments were useful in obtaining some of the needs and preferences of different user groups.

Originality/value

Multi-phase user tests were conducted to identify and to evaluate the requirements and preferences of remote operators using a simplified HMI. Training analysis provides important aspects to consider for the training of future users.

Abstract

Purpose

The purpose of this paper is to consider the enrolment at university and the subsequent possible dropout as a piece of the school-to-work transition and ask whether it improves or worsens the labour market outcomes a few years after graduation from the high school.

Design/methodology/approach

The analysis exploits data from the upper secondary graduate survey by ISTAT on a cohort of high school graduates and investigates the effect of dropping out four years after graduation. The labour market outcomes of university dropouts are compared to the outcomes of high school graduates who never enrolled at university. A propensity score matching approach is applied. The model is also estimated on the subsamples of males and females.

Findings

The findings show that spending a period at university and leaving it before completion makes the transition to work substantially more difficult. Both the probability of being NEET and getting a bad job increase in the case of dropout, while no relevant effect is found on earnings. Moreover, the impact of university dropout tends to be more harmful the longer the spell from enrolment to dropping out. Separate estimates by gender point out that females appear to be relatively more affected in the case of dropping out without a fallback plan.

Originality/value

While the existing studies in the literature on the school-to-work transition mostly focus on the determinants of the dropout, this paper investigates whether and how the employment outcomes are affected by dropping out in Italy. Moreover, university dropouts are compared to high school graduates with no university experience, rather than to university graduates. Finally, evidence on the mechanisms driving the effect of dropping out is provided, by considering timing and motivations for dropping out.

Abstract

Urbanization is a mode of social progress in history. However, it repeats headway and fallback. In the lifetime of a person, he/she may watch only a certain phase of recovery from fallback as if it were a phase of progress. Such a social activity as evocation of sense of togetherness may seem to be so primitive that it might be practicable even in past communities. It is true of water quality issue of river and sea around us. Do you find the more innovative way that has never been seen? Otherwise, do you chant simply a slogan like “Clean the river more!”? Although water quality transition is merely a physical phenomenon, the community nearby may either worsen or improve the quality. The interaction between the quality transition and the action of community continues in a dynamic process. Community should progress, if possible, by managing the process appropriately. This chapter first illustrates a case of social remediation process for water quality issue of Horikawa river in Nagoya City, Japan. Then it considers the issues, concerns, activities, and moreover the relation of them over the water community. It finally refers to more strategic direction through simple mathematical formulation of social remediation process.

Abstract

Investigation into negotiation has shown that there is a correlation between high expectations and the results attained: “the higher the expectations, the better the results”. This study investigates other effects of expectations on results including the influence of equally high expectations by both negotiators, the influence of the fallback position at which a negotiator is willing to settle, and the relative influence of high and low expectations on outcome, all of which are critical to managers who are negotiating either purchases or sales. In this study, negotiation experiments encompassing a total of 24 negotiations were conducted. The study demonstrated that the negotiator with the highest aspiration level did not necessarily win when both sides had similar aspiration levels. Moreover, it was found that maximum aspiration has a greater influence on positive outcome than minimum aspiration (fallback position) and that high aspiration has a greater influence on positive outcome than low aspiration.

Abstract

Purpose

The purpose of the paper is to investigate the nature of variations among established and emerging middle class consumers in South Africa in response to the institution context factors associated with emerging markets that are established in international business studies.

Design/methodology/approach

An exploratory research approach using semi-structured expert interviews was used to collect data.

Findings

Key findings indicate distinct approaches in dealing with factors such as different fallback positions, asset ownership, education, language, family responsibility, career aspirations and risk protection in the middle class process of attaining and sustaining middle class status.

Research limitations/implications

The focus on one country has the potential to minimize the generalizability of findings from the study, however, South Africa has a significantly high proportion of sub-Saharan middle class consumers. This provides a basis for further a basis for further research into other sub-Saharan African countries.

Practical implications

Findings from the study provide practical insights on risk profiling of middle-class consumers for marketing practitioners.

Social implications

The study provides insights into the distinct variations between emerging and established middle class consumers in areas such as language and education. These insights have potential implications on the implementation of government policies such as the Empowerment Policy and consumer protection.

Originality/value

The paper expands the research agenda in the area of middle class consumer behavior in emerging markets. By concentrating on South Africa, the research expands existing knowledge beyond emerging giants like China and India, which are often a focus in literature.

Abstract

As the only country in the world in which Hebrew is the official language, Israel found it necessary to develop software enabling its research library catalogs from the outset to handle two alphabets—Hebrew (including Yiddish and Ladino) and Roman characters. Starting in 1981, ALEPH, Israel's research library network, utilized locally developed software that could provide both a Hebrew and Roman mode. However, since the nation's research libraries had large collections in Arabic and Cyrillic languages, an urgent need arose for a system that could also handle Arabic and Cyrillic materials. This led to the development of soft fonts, software instead of the hardware‐based Hebrew‐English solution that was incorporated in ALEPH's earlier versions. The soft fonts can display on any VT320 or upwardly compatible terminal in Roman‐alphabet, Hebrew, Arabic, and Cyrillic. Furthermore, in the Hebrew and Arabic modes, the language of communication with the computer (commands, HELP, and so on) are also in the vernacular. This article focuses on some of the problems and solutions involved in developing ALEPH's multi‐script, bi‐directional system.

Abstract

Purpose

Summarize and review the key developments during the first three-quarters of 2021 relating to transition of the London InterBank Offered Rate (LIBOR) to alternative risk-free rates, in accordance with the guidance of global regulators and market participants.

Design/methodology/approach

Outlines and explains four key events to date during 2021 that are instrumental to the success of LIBOR transition, including the ISDA 2020 IBOR Protocol and Supplement, the 5 March 2021 announcements by ICE Benchmark Administration and the Financial Conduct Authority, the transition of interdealer swap conventions from LIBOR to SOFR, and the ARRC endorsement of the CME Group SOFR term rate.

Findings

The global adherence to the ISDA Protocol and Supplement, the successful launch of “SOFR First” and other “RFR First” swaps convention transitions, and the ARRC’s endorsement of CME’s SOFR term rate have given the market the clarity and tools that it needs to complete the transition away from LIBOR by the deadlines fixed by the 5 March 2021 benchmark transition event.

Practical implications

It now is clear that market participants globally have the resources to, and must, move to adopt alternative reference rates and related operational systems and other infrastructure to cease origination of new LIBOR-linked contracts after 31 December 2021. The ARRC’s endorsement of the SOFR term rate for business loans and related derivatives and securitizations is a critical positive development for the structured finance market.

Originality/value

Expert analysis and guidance from experienced finance lawyers.

Abstract

The debate about in equality has concentrated on trade and/or technology as potential explanations. This paper argues that openness or globalisation in general, instead of the narrow definition of trade, is an important component missing from the discussion about in equality trends. To be specific, openness allows firms to increase their fallback position by presenting a credible threat of relocation. Firms do not have to actually relocate; they just have to present a credible threat to undermine worker’s welfare. This area of research, currently underdeveloped, could potentially improve our discussion about in equality.
