Abstract
Purpose
The purpose of this paper is to design a unified operational design domain (ODD) monitoring framework for mitigating Safety of the Intended Functionality (SOTIF) risks triggered by vehicles exceeding ODD boundaries in complex traffic scenarios.
Design/methodology/approach
A unified model of ODD monitoring is constructed, which consists of three modules: weather condition monitoring for unusual weather conditions, such as rain, snow and fog; vehicle behavior monitoring for abnormal vehicle behavior, such as traffic rule violations; and road condition monitoring for abnormal road conditions, such as road defects, unexpected obstacles and slippery roads. Additionally, the applications of the proposed unified ODD monitoring framework are demonstrated. The practicability and effectiveness of the proposed unified ODD monitoring framework for mitigating SOTIF risk are verified in the applications.
Findings
First, the application of weather condition monitoring demonstrates that the autonomous vehicle can make a safe decision based on the performance degradation of Lidar on rainy days using the proposed monitoring framework. Second, the application of vehicle behavior monitoring demonstrates that the autonomous vehicle can properly adhere to traffic rules using the proposed monitoring framework. Third, the application of road condition monitoring demonstrates that the proposed unified ODD monitoring framework enables the ego vehicle to successfully monitor and avoid road defects.
Originality/value
The value of this paper is that the proposed unified ODD monitoring framework establishes a new foundation for monitoring and mitigating SOTIF risks in complex traffic environments.

Abstract
For organizations to be effective, their employees need to rely upon each other even when they do not trust each other. One tool managers can use to promote trust-like behavior is monitoring. In this chapter, we report results from a laboratory study that describes the relationship between monitoring and trust behavior. We randomly and anonymously paired participants (n=210) with the same partner, and had them make 15 rounds of trust game decisions. We find predictable main effects (e.g. frequent monitoring increases trust behavior) as well as interesting strategic behavior. Specifically, we find that anticipated monitoring schemes (i.e. when participants know before they make a decision that they either will or will not be monitored) significantly increase trust behavior in monitored rounds, but decrease trust behavior overall. Participants in our study also reacted to information they learned about their counterpart differently as a function of whether or not monitoring was anticipated. Participants were less trusting when they observed trustworthy behavior in an anticipated monitoring period, than when they observed trustworthy behavior in an unanticipated monitoring period. In many cases, participants in our study systematically anticipated their counterpart's untrustworthy behavior. We discuss implication of these results for models of trust and offer managerial prescriptions.

The purpose of this paper is to reduce the inrush current and dip in voltage for energy‐ saving purposes in relation to residential air‐conditioning systems.
Abstract
Purpose
The purpose of this paper is to reduce the inrush current and dip in voltage for energy‐ saving purposes in relation to residential air‐conditioning systems.
Design/methodology/approach
The paper focuses on the experimental harmonic investigation of a window‐type residential AC unit line current under time‐based soft‐starting control strategy. The control strategy assumes that only source voltage and current measurements are available. The soft‐starter is based on power electronic devices controlled through a firing signal generated by a programmed microcontroller during the first 500 ms.
Findings
The harmonic content shows the effect of the soft‐starter in exciting high‐frequency components of the line current. Harmonics investigations show that the high frequencies – even or odd multiples – of the fundamental line frequency are all excited by the soft‐starter approach. Some of these frequencies may harm the life cycle of the air‐conditioner.
Research limitations/implications
The real data harmonic analysis shows that the adopted approach excites the entire frequency spectrum of the signal. A better monitoring of the harmonics is required. A closed loop adaptive soft‐starting control may perform much better than a time‐based soft‐starting strategy.
Originality/value
The paper assesses the power quality related to time‐based soft‐starting strategy of a residential air‐conditioning system to reduce the inrush current and the dip in voltage, both with a serious effect on energy savings, especially when the AC load is around 65 per cent of the total power demand load.

The purpose of this study is to identify the association between risky sexual behaviors and migration intentions among adolescents living in Guanajuato, Mexico.
Abstract
Purpose
The purpose of this study is to identify the association between risky sexual behaviors and migration intentions among adolescents living in Guanajuato, Mexico.
Design/methodology/approach
Data were collected by self‐administered questionnaires to students enrolled in an alternative schooling system in Guanajuato, Mexico, during the school year of 2006‐2007. The sample size for this study includes 538 unmarried students, 35 percent male, ages 14‐19. Ordinal logistic regression is used to estimate the odds of engaging in risky sexual behaviors.
Findings
The results reveal that male adolescents with higher intentions to migrate have significantly higher odds of engaging in risky sexual behaviors than both males who are less interested in migrating and females, regardless of their migration intentions.
Practical implications
Interventions on both sides of the US/Mexico border are needed in order to address this concern particularly among males who express a desire to migrate to the US someday.
Social implications
These findings highlight the importance of examining risky sexual behaviors even before migration to the US occurs. By engaging in high risk sexual behaviors prior to migrating, adolescents are putting themselves and both their sexual partners in Mexico and their future sexual partners in the US at increased risk of contracting STIs and HIV.
Originality/value
The study examined risky sexual behavior of adolescents in Mexico prior to migration. Knowledge about risky sexual behaviors prior to departure is vital for policy makers and researchers as they seek to design and implement interventions aimed at quelling this growing public health concern.

Abstract
This chapter examines how and why Asian bookmakers have surpassed the rest of the sports gambling market in betting volume. It critically unpacks the size, structure and operations of this market, before examining the globalisation of match-fixing that accompanies this, largely, unregulated market. While there has been some excellent research on the structure of the Black/Red Mafia controlled gambling in Communist China or match-fixing in national markets like South Korea and Taiwan, this chapter is one of the first comprehensive examinations of the globalised Asian gambling market and its contribution to sports corruption.

Abstract
Purpose
This study aims to evaluate and investigate the existing process of establishing a banking relationship with politically exposed persons.
Design/methodology/approach
This study used qualitative techniques of semi-structured interviews with senior compliance officers of financial institutes in Pakistan.
Findings
This study found that the existing mechanism of identification and verification of politically exposed persons (PEPs) is ineffective. Financial institutes face challenges like the quality of name screening data sets, cost of identification and verification, role and control of the regulator, the influence of politically exposed persons, the opaqueness of laws and international connections of the politically exposed persons. Further, financial Institutes are burdened by regulators to perform robust PEP customer due diligence but do not guide and provide the right tools.
Originality/value
This paper aims to find challenges faced by financial institutes before onboarding the PEPs. Further, very limited studies on this topic have been conducted in Pakistani context.

Abstract
Purpose
Investigating employee responses to relational fulfilment of the psychological contract and work‐life benefits of a telecommuting program, this study aims to contribute to the literature on social exchange in employment.
Design/methodology/approach
The setting of the study was the German public administration. Survey data from 947 Civil Servants were analyzed in structural equation models. Analysis of mean structure was used to compare telecommuting participants (n=601) and regular workers (n=346).
Findings
Trust and affective commitment consecutively mediated between relational fulfilment of the psychological contract and organizational citizenship behavior. Members of the telecommuting program had more positive representations of social exchange, reporting higher levels of fulfilment, trust, and commitment than their peers.
Research limitations/implications
Reliance on cross‐sectional self‐report data poses a limitation. Selection effects in the quasi‐experimental design for comparing telecommuters and regular employees cannot be ruled out. Generalizability to more transactional or short‐term employment is debatable.
Originality/value
The study adds to a more integrated understanding of the psychological processes that reinforce and strengthen employee trust and commitment, thus forming the basis of the motivation to go above and beyond specified duties and reward‐contingent behavior.

Abstract
Purpose
The purpose of this paper is to evaluate the specific reasons for the Turkish women in the Turkish Republic of Northern Cyprus not reaching the same level of achievement in the political sphere as their male counterparts. The aim is to draw attention to the extremely low participation of women in politics (6 per cent) and suggest possible solutions to increase it.
Design/methodology/approach
The study consists of interviews with seven women who played an active role in politics and who are still in the political arena as parliamentarians or ministers.
Findings
It was found that the major political problem of the island, “the Cyprus problem”, has had a significant impact on the confinement of women in the private sphere. In addition, the divided land constitutes a higher restriction on women. Moreover, gatherings in coffeehouses and the time of such meetings are important difficulties. Furthermore, the women's branches of the political parties constitute a serious barrier.
Research limitations/implications
The study focuses on a part of a small island, Cyprus. Therefore, it was possible to interview only seven women politicians.
Practical implications
This paper is functional and interesting for those working with gender equality, particularly the obstacles that women face and their secondary role in the political arena.
Originality/value
This paper provides new empirical data on gender equity in the context of the Turkish Cypriots and critically analyzes the specific situation of women politicians living on the island.

Abstract
Ion Deposition Ltd is a new company established in Corby, Northamptonshire, as part of the SATRA Group of companies which specialises in international operations in the metals business. IDL has been set up as a specialist coating facility — with the support of the Department of Trade and Industry — initially offering ion vapour deposition of aluminium to, in particular, the Aerospace Industry. Significant investment has been made in equipment and facilities, including the latest state‐of‐art ivadizer from McDonnell Douglas. The vacuum chamber is capable of accepting a component 5ft by 10ft, yet has a barrel coating insert for the processing of large volumes of small parts like rivets and fasteners. The coater is also fitted with the capability of the first cryogenic pumping system, which achieves lower vacuums quickly and efficiently. The IDL plant has been in full operation for seven months, and has already established a firm Aerospace orientated customer base both in the U.K. and mainland Europe. Future plans include the expansion of the Corby facility to include other highly specialised coating services to meet the needs of ‘high tech’ industries in the 1990s'.
