Managers of defined-benefit (DB) firms have considerable discretion in deriving pension costs and flexibility in cash contributions to pension plans. Pension accruals occur when cash contributions differ from pension costs. The manipulable nature of pension costs and cash contributions allows managers of DB firms to manipulate pension accruals to achieve their desired earnings. We study whether DB firms with earnings management attributes (referred to as suspect DB firms) used more discretionary pension accruals (DPA) than non-suspect DB firms, especially after the passage of Sarbanes-Oxley (SOX).

The authors develop an aggregate measure of DPA to capture overall earnings management in pension accounting. They then employ a multivariate regression model to study whether the suspect DB firms engage in more DPA than non-suspect firms and to assess the impact of SOX on DPA for all DB firms and for suspect DB firms.

The authors find evidence that suspect firms inflate DPA to achieve their earnings goals and also that all DB firms and the suspect firms use more DPA in the post-SOX era compared to the pre-SOX period. In contrast, they observe no significant difference in real activities earnings management (REM) between suspect and non-suspect firms. In addition, neither the entire sample of DB firms nor the suspect firms display a significant change in REM after SOX.

The samples in the study are limited to firms with defined pension plans; thus, the findings cannot be generalized to all firms. In addition, as in other empirical studies relying on models to estimate earnings management proxies, this study inherits estimation errors from Jones and Roychowdhury's models. Consequently, the impact of these estimation errors cannot be ruled out.

The empirical findings of the study appear that instead of deterring DB firms from engaging in pension accruals earnings management, enacting the stringent anti-fraud SOX prompts these firms to rely more on accrual-based discretionary pension rather than switch to real activities manipulation to manage earnings.

While many prior studies focus on the impact of managing individual pension assumptions on earnings, the authors study overall earnings management in pension accounting by developing a model to derive an aggregate measure of pension earnings management.

A distributed piezoelectric actuator (DPA) improving the deformation performance of wing is proposed. As the power source of morphing wing, the factors affecting the driving performance of DPA were studied.

The DPA is composed of a substrate beam and a certain number of piezoelectric patches pasted on its upper and lower ends. Utilizing the inverse piezoelectric effect of piezoelectric material, the DPA transfers displacement to the wing skin to change its shape. According to the finite element method and piezoelectric constitutive equation, the structure model of DPA was established, and its deformation behavior was analyzed. The accuracy of algorithm was verified by comparison with previous studies.

The results show that the arrangement way, length and thickness of piezoelectric patches, the substrate beam thickness and the applied voltage are the important factors to determine the driving performance of DPA.

This paper can provide theoretical basis and calculation method for the design and application of distributed piezoelectric actuator and morphing wing.

A novel morphing wing drove by DPA is proposed to improve environmental adaptability of aircraft. As the power source achieving wing deformation, the DPA model is established by FEM. Then the factors affecting the driving performance are analyzed. The authors find the centrosymmetric arrangement way of piezoelectric patches is superior to the axisymmetric arrangement, and distribution center of the piezoelectric patches determines the driving performance.

This chapter demonstrates that while in most late modern societies there is a neoliberal hegemony to expand police Closed-Circuit Television (CCTV) surveillance for crime control and antiterrorism, in Greece there is serious controversy and resistance against the post-Olympic use of more than 1,200 Olympic CCTV cameras. Drawing on the interesting politics of CCTV expansion and resistance, the chapter traces the reasons why, in the Greek context, this very expensive Olympic surveillance “dowry” has been opposed, even for traffic control. It critically attributes Greek citizens’ fear and mistrust primarily to their past police-state experience of authoritarian, thought-control surveillance.

Deferred prosecution agreements (DPAs) are the tool of choice for federal prosecutors when adjudicating corporate misconduct. A DPA is a negotiation that permits the allegedly guilty party from undergoing a criminal trial if they avoid committing further wrongdoing for a specified period. This paper aims to examine whether DPAs are a beneficial mechanism for the criminal justice system to use while adjudicating corporate misconduct. By conducting in-depth semi-structured qualitative interviews with 24 practitioners in the legal field and white-collar crime experts, this study identifies the shortcomings and advantages of DPAs and highlights what policy enactments might enhance their application. The study contributes to the existing literature by expanding the narratives used by judicial officials, legal practitioners and white-collar crime scholars on the role of DPAs.

The current study is an in-depth qualitative analysis that explores judicial actors’ and white-collar crime scholars’ opinions on the adoption of DPAs to adjudicate corporate misconduct. The literature on DPAs is currently derived primarily from law and literature reviews published by legal scholars. Clandestine negotiations are not accessible to the public and are frequently kept in sealed files unless a breach of contract occurs, resulting in the case proceeding to trial. Hence, a qualitative analysis is the best approach to evaluate the effectiveness of DPAs. Further, little evidence is available that focuses on the opinions of professionals who have participated in these agreements. The interviews were conducted over Zoom and lasted an average of 43 min, with the longest interview spanning 1 h and 45 min and the shortest interview being 14 minutes. A non-probability sampling method – specifically, snowball sampling – was used to generate a total sample of 24 legal professionals and white-collar crime scholars. Initial participants were found by contacting law offices specializing in white-collar crime litigation and using current networks to attain access to a broader range of participants. Then, 19 participants provided referrals throughout the study. The final sample consisted of nine government officials, eight legal practitioners and seven white-collar crime academics experts. One of the government official interviews was excluded from the final research project due to a lack of expertise in the field of white-collar crime. The interview questions were designed to promote in-depth conversation and insight into personal opinions on the adoption of DPAs. Several inquiries highlighted whether DPAs are an appropriate response to corporate misconduct and whether they reduced recidivism through their intended deterrent effect. Furthermore, several descriptive questions sought to understand which criminal justice actors support the adoption of DPAs in white-collar crime cases and why. Coding of the data was first conducted individually by each author. The researchers then compared thematic findings that reflected consensus.

An immediate theme identifiable in the research is the intrinsic value that DPAs offer in adjudicating corporate wrongdoing. As indicated by a participant, corporate misconduct is not “black or white,” stressing the importance of prosecutors having a middle ground between criminal prosecution and the dismissal of charges. A judicial official indicated that “DPAs are another essential arrow in a prosecutor’s quiver – and something a defense attorney can bargain for” (Respondent 5). Seven government officials and legal practitioners noted that you are unable to send a corporation to jail, and you do not simply want to put them out of business; thus, a DPA is the only tool in which the government can mandate structural change in a company without dismantling the entire entity. Only three academics concurred with the government officials and legal practitioners that DPAs are beneficial and offer prosecutors a vital middle ground. One academic, for example, stated that “DPAs have given U.S Attorney offices that ability to be involved for a considerable amount of time in a company's business, while simultaneously promoting change within the entity” (Respondent 14). Additionally, DPAs ensure that corporations are held criminally liable without triggering an endless cycle of collateral consequences for innocent third parties. One legal practitioner, for example, stated: “Just look at the Enron case; they charged Arthur Andersen with obstruction of justice and dismantled the entire entity they made it where the business was never going to come back. A small subset of individuals, in this case, should have been held responsible but instead, hundreds and if not thousands of people were harmed. With this in mind, DPAs are extremely important, in that it limits collateral consequences because DPAs take a more holistic view that criminal prosecution does not consider” (Respondent 21). Another respondent highlighted that “DPAs are the only tool available that can be employed to change an entire organization structurally” (Respondent 20). Ultimately, the findings suggest that there is a consensus among respondents that DPAs are an appropriate response to corporate misconduct, particularly when the agreement stipulates that a company must hire an external compliance monitor and update their current compliance system. Overall, participants emphasized that these stipulations promote a sense of corporate accountability, provide for the dismissal of guilty employees and mandate structural change. The majority of the respondents (n = 20) insisted that DPAs are advantageous, yet a subset of participants were skeptical of their use in white-collar crime prosecutions. One legal practitioner, for example, noted that “DPAs are political creatures that are awarded as political favors to the largest of corporations that our economy relies upon” (Respondent 17). Another government official confirmed this statement, indicating that “DPAs are a mere slap on the wrist for large corporations – they simply see it as doing business” (Respondent 6). Four academic participants emphasized that DPAs are typically negotiated with multi-level corporations and are not extended to the small businesses that suffer the dire consequences of criminal prosecution. One academic, for instance, stressed that “the question becomes is it fairly applied and being implemented properly. Larger companies are more likely to receive and benefit from a DPA, thus, raising the question of fairness” (Respondent 12). Another academic who was previously a government official stated: “DPAs risk abuse – there have been several instances where prosecutors have forced companies to donate money to favored charities and overstepped their powers. Sometimes DPAs also come with monitors. For example, banks typically have to pay for the auditor, and it becomes extremely intrusive, and it it not clear that they are efficient.”

Several limitations exist in this research. First, it is not a comprehensive study that is representative of the larger population, which limits generalizability. Given the contention of research on DPAs, this qualitative research contributes to the literature, and its findings are likely transferable to multiple settings in which DPAs are used. Second, DPAs are processed and drafted differently across jurisdictions; thus, comparing DPAs across state levels and among departments in the federal government would be equivalent to comparing apples to oranges. This comparison is yet another limitation to the study because criminal justice practitioners operate in both the state and federal jurisdictions. Another challenge in the current study and something that likely will be a problem for future researchers is the difficulty of gaining access to experts in an exclusive field of criminal justice, such as federal prosecutors, Department of Justice officials, federal judges and elite corporate defense attorneys. Ultimately, several obstacles arose during the study, particularly when recruiting participants to gain a large enough sample size to conduct meaningful analysis. This resulted in smaller sample size but rich, in-depth data that achieved saturation among participants.

Several policy implications are identifiable. First, it appears that DPAs are a mainstay of white-collar crime prosecution. No participants advocate for their complete removal from the prosecution process. Participants highlight that DPAs occupy an essential middle-ground between dismissal and criminal charges. Without this mechanism, prosecution would be impeded, and holding corporate criminal actors liable would increasingly become formidable. Although it appears that the system cannot function without DPAs, several respondents emphasize that we must begin to hold individuals accountable alongside corporations. Another policy implication that a minority of participants mentioned within the study involves ensuring that our compliance monitoring system operates appropriately. A majority of participants note that the overarching stipulation that promotes structural change within an organization is adopting a functioning compliance monitoring system, thus, emphasizing the importance of this process operating smoothly and ethically. The selection of an independent compliance monitor may be problematic. For example, a former government compliance monitor notes that not all monitors are experts in the field they are overseeing. A pharmaceutical expert, for example, may be attempting to regulate an automotive organization, which may present unique challenges. An agency of federal professionals dedicated to supervising specific industries such as automotive, pharmaceutical and financial would ensure that organizations are actually implementing the terms of the DPA.

Ultimately, the current research highlights the necessity of empirically studying the benefits and drawbacks of such agreements. Future research on the topic remains onerous due to the scarcity of a centralized database that contains extensive details of DPAs. The present study suggests that the verdict on DPAs is undecided, with more than half of the study's criminal justice professionals advocating for their continued and even increased use. However, about half of the participants, particularly academics, called attention to the agreements’ potential bias. The disagreement among participants is most contentious in the consideration of a DPA centralized database which would immensely aid future research and policy advancements.

The purpose of this paper is to discuss the UK National DNA Database (NDNAD) and some of the controversies surrounding it with reference to legal and ethical issues, focusing particularly on privacy and human rights. Governance of this database involves specific exemptions from the Data Protection Act (DPA), and this gives a rise to concerns regarding both the extent of surveillance on the UK population and the possibility for harm to all citizens. This is of wider importance since every current citizen, and everybody who visits the UK, could become a record in the DNA database. Principally, the paper seeks to explore whether these exemptions would also imply exemptions for software developers from codes of practice and ethics of their professional societies as relate to constructing or maintaining such data and the database.

The paper makes a comparison between the principles of the DPA, as would need to be followed by all other organizations handling personal data, professional responsibilities‐based codes of ethics of professional societies, and the current reality as reported in relation to the NDNAD and the exemptions offered through the DPA.

Primarily, if NDNAD was not exempted from certain provisions in the DPA, the potential for the kinds of data leakages and other mishandlings could largely be avoided without the need for further considerations over so‐called “data minimization”. It can be seen how the lack of afforded protection allows for a wide range of issues as relate at least to privacy.

The paper provides the first evaluation of the combination of law, codes of ethics, and activities in the real world as related to NDNAD, with concomitant considerations for privacy, liberty, and human rights. Originality is demonstrated through consideration of the implications of certain exemptions in the DPA in relation to crime and taxation and national security and in relating the expected protections for personal data to widely reported evidence that such protections may be variously lacking. In addition, the paper provides a broad overview of controversies over certain newer kinds of DNA analysis, and other relatively recent findings, that seem generally absent from the vast majority of debates over this kind of analysis.

This study aims to investigate the possible use of a deep neural network (DNN) as an inverse solver.

Different models based on DNNs are designed and proposed for the resolution of inverse electromagnetic problems either as fast solvers for the direct problem or as straightforward inverse problem solvers, with reference to the TEAM 25 benchmark problem for the sake of exemplification.

Using DNNs as straightforward inverse problem solvers has relevant advantages in terms of promptness but requires a careful treatment of the underlying problem ill-posedness.

This work is one of the first attempts to exploit DNNs for inverse problem resolution in low-frequency electromagnetism. Results on the TEAM 25 test problem show the potential effectiveness of the approach but also highlight the need for a careful choice of the training data set.

Why is it that when you present a report to some managers, they read it through in great detail whilst others scarcely read it at all?

This study explores the scope, materiality and extent of environmental and social sustainability disclosure – as benchmarked against the Global Reporting Initiatives (GRI-G4) – of the top 10 logistics firms operating in Australia. It also investigates the relationships between the extent of environmental and social sustainability disclosure of these firms and their actual financial performance.

The authors adopted an inductive case study approach for an in-depth investigation of the relationships among concepts. A content analysis of the firms' sustainability reports was performed to determine their pattern and extent of sustainability disclosure against the GRI framework. A disclosure–performance analysis (DPA) matrix was employed to relate the extent of environmental and social sustainability disclosure of these 10 firms with their actual financial performance (i.e. return on assets [ROA] and total revenue growth).

This study found that the extent of sustainability reporting was relatively high on the labour practices and decent work subgroup, followed by the environmental dimension of the GRI-G4 framework. However, it was relatively low on the society, human rights and product responsibility subgroups of the GRI framework. The DPA revealed that “Leaders” (firms with higher sustainability disclosure levels) achieved significantly higher ROA. However, “Opportunists” (firms with lower sustainability disclosure levels) achieved higher levels of financial returns (i.e. ROA and total revenue growth) with less attention to sustainability issues, which contradicts the win-win view of the sustainability disclosure–financial performance relationship.

First, this study contributes an in-depth review of sustainability disclosure practices of top logistics firms operating in Australia. Second, using DPA, it identifies the novel effects of environmental and social sustainability disclosure levels on these firms' financial performance. It also sheds further light on the potential effect of investments beyond substantial profitability for sustainability growth and corporate governance on the sustainability disclosure–financial performance relationship.

This paper aims to propose a practical design methodology of high-power wideband power amplifier.

The distributed power amplification method is used for a Gallium Nitride device to achieve wideband operation. To achieve the high power without trading-off the bandwidth and gain, a methodology to extract the package-loading effect is proposed and verified.

A maximum output power of 10 W is achieved from 100 MHz to 2 GHz with a wideband power gain of 32 dB in measurement. This performance is achieved through a single section matching network.

Measurement accuracy is dependable to the thermal behaviour of the high-power device.

The proposed technique is an excellent solution to be used in the two way radio power amplifier that minimizes the fundamental trade-off issue between power, gain, bandwidth and efficiency.

In this work, a practical distributed power amplifier (DPA) design methodology is proposed that reduces the development cycle time for industrial engineers working on high-power circuit design application.

The purpose of this study was to investigate the difference between South Africa (SA) and the United Kingdom (UK) in terms of data protection compliance with the aim to establish if a country that has had data protection in place for a longer period of time has a higher level of compliance with data protection requirements in comparison with a country that is preparing for compliance.

An insurance industry multi-case study within the online insurance services environment was conducted. Personal information of four newly created consumer profiles was deposited to 10 random insurance organisation websites in each country to evaluate a number of data privacy requirements of the Data Protection Act and Protection of Personal Information Act.

The results demonstrate that not all the insurance organisations honored the selected opt-out preference for receiving direct marketing material. This was evident in direct marketing material that was sent from the insurance organisations in the sample to both the SA and UK consumer profiles who opted out for it. A total of 42 unsolicited third-party contacts were received by the SA consumer profiles, whereas the UK consumer profiles did not receive any third-party direct marketing. It was also found that the minimality principle is not always met by both SA and UK organisations.

As a jurisdiction with a heavy stance towards privacy implementation and regulation, it was found that the UK is more compliant than SA in terms of implementation of the evaluated data protection requirements included in the scope of this study, however not fully compliant.

Based upon the results obtained from this research, it suggests that the SA insurance organisations should ensure that the non-compliance aspects relating to direct marketing and sharing data with third parties are addressed. SA insurance companies should learn from the manner in which the UK insurance organisations implement these privacy requirements. Furthermore, the UK insurance organisations should focus on improved compliance for direct marking and the minimality principle. The study indicates the positive role that data protection legislation plays in a county like the UK, with a more mature stance toward compliance with data protection legislation.
