An Internet Access Solution: MANET Routing and a Gateway Selection Approach for Disaster Scenarios

After natural and man-made disasters, the telecommunication infrastructure is usually severely damaged, thus hampering communication and rescue services. It is impossible for disaster victims to make use of communication devices such as cellular phones, iPads, or their laptops to make a connection with the outside world (Internet). With infrastructure less and decentralized features, the mobile ad hoc network (MANET) can play an important role in improving communication in post-disaster affected areas. Therefore, the important functionalities of a MANET that allow users to create dynamically configurable wireless networks without fixed infrastructure using common devices such as mobile phones is necessary. This paper reports on the development of new techniques for routing selection and gateway load balancing in MANETs. Network fairness, throughput, and packet delays are measured empirically. The proposed mechanisms can reduce network congestion and consequently improve communication in affected areas.     

What is the impact of corruption on audit fees?

This study examines the impact of country-level corruption on audit fees. Using a sample of 102,934 companies from 48 countries over the period 1998–2014, the authors find that audit fees are positively associated with higher levels of corruption. They also discovered that corruption adds a significant margin to the premium paid to Big 4 (Deloitte Touche Tohmatsu, PricewaterhouseCoopers, Ernst & Young and KPMG) auditors. The study opens up a new line of research and adds significantly to the academic literature on the Big 4 audit premium.

IMPACT

The study has several important implications for academics and policy-makers. These include discussion of the factors driving corruption and the role of auditing. Knowledge of the factors driving corruption should guide policy-makers to adoption of polices that could reduce corruption. The finding that audit fees are positively associated with corruption, as well as with audit quality, points to the potential for auditing as a tool for corruption control beyond its traditional role as an assurance service.

Organic versus cosmetic efforts of the quality of carbon reporting by top New Zealand firms. Does market reward or penalise?

This study explores the quality of carbon reporting (QCR) by New Zealand (NZ) firms and its changes over time. It also explores the impact of QCR on the market reputation of firms. Using a sample of 300 company-year observations between 2015 and 2020 from top listed firms of NZ, the study develops a 14-item QCR index. The study finds that the company-level QCR reporting by NZ firms overall is not praiseworthy, as firms need to improve QCR in many aspects (both in-house efforts as well as external reporting). Although QCR has increased over time, firms' QCR efforts cannot be treated completely authentic. Majority of firms in NZ have disclosed unaudited carbon information to investors and other stakeholders. Additionally, our study finds that QCR positively affects the market reputations of firms, and the market behaves accordingly. Specifically, firms' organic carbon efforts are paid-off (through increased market reputation) by the market players and cosmetic/decoupled behaviour is penalised (through decreased market reputation). This study is the first on QCR reporting using a sample of NZ firms and an account of their initiatives towards the carbon emission reduction initiative and related disclosures. The study's findings have policy implications.
