Securing the Participation of Safety-Critical SCADA Systems in the Industrial Internet of Things
In the past, industrial control systems were ‘air gapped’ and
isolated from more conventional networks. They used
specialist protocols, such as Modbus, that are very different
from TCP/IP. Individual devices used proprietary operating
systems rather than the more familiar Linux or Windows.
However, things are changing. There is a move for greater
connectivity – for instance so that higher-level enterprise
management systems can exchange information that helps
optimise production processes. At the same time, industrial
systems have been influenced by concepts from the Internet
of Things; where the information derived from sensors and
actuators in domestic and industrial components can be
addressed through network interfaces. This paper identifies a
range of cyber security and safety concerns that arise from
these developments. The closing sections introduce potential
solutions and identify areas for future research
Executive Compensation and Corporate Governance in China
We investigate executive compensation and corporate governance in China’s publicly traded firms. We also compare executive pay in China to the USA. Consistent with agency theory, we find that executive compensation is positively correlated to firm performance. The study shows that executive pay and CEO incentives are lower in State controlled firms and firms with concentrated ownership structures. Boardroom governance is important. We find that firms with more independent directors on the board have a higher pay-for-performance link. Non-State (private) controlled firms and firms with more independent directors on the board are more likely to replace the CEO for poor performance. Finally, we document that US executive pay (salary and bonus) is about seventeen times higher than in China. Significant differences in US-China pay persist even after controlling for economic and governance factors
Towards resilience through systems-based plant breeding. A review
How the growing world population can feed itself is a crucial, multi-dimensional problem that goes beyond sustainable development. Crop production will be affected by many changes in its climatic, agronomic, economic, and societal contexts.
Therefore, breeders are challenged to produce cultivars that strengthen both ecological and societal resilience by striving for
six international sustainability targets: food security, safety and quality; food and seed sovereignty; social justice;
agrobiodiversity; ecosystem services; and climate robustness. Against this background, we review the state of the art in plant
breeding by distinguishing four paradigmatic orientations that currently co-exist: community-based breeding, ecosystem-based
breeding, trait-based breeding, and corporate-based breeding, analyzing differences among these orientations. Our main findings
are: (1) all four orientations have significant value but none alone will achieve all six sustainability targets; (2) therefore, an
overarching approach is needed: “systems-based breeding,” an orientation with the potential to synergize the strengths of the
ways of thinking in the current paradigmatic orientations; (3) achieving that requires specific knowledge development and
integration, a multitude of suitable breeding strategies and tools, and entrepreneurship, but also a change in attitude based on
corporate responsibility, circular economy and true-cost accounting, and fair and green policies. We conclude that systems-based
breeding can create strong interactions between all system components. While seeds are part of the common good and the basis of
agrobiodiversity, a diversity in breeding approaches, based on different entrepreneurial approaches, can also be considered part of
the required agrobiodiversity. To enable systems-based breeding to play a major role in creating sustainable agriculture, a shared
sense of urgency is needed to realize the required changes in breeding approaches, institutions, regulations and protocols. Based
on this concept of systems-based breeding, there are opportunities for breeders to play an active role in the development of an
ecologically and societally resilient, sustainable agriculture
Public Sector Unions: Will They Thrive or Struggle to Survive?
[Excerpt] There is emerging consensus among public sector union leaders at the national level1 that the threats they face today are eerily similar to those ignored by private sector unions 20 years ago. Privatization, reinventing government, a changing public sector work force, anti-government forces on Capitol Hill and in statehouses, union myopia, and member apathy all are taken with the utmost seriousness. The situation calls for a sophisticated strategic response. Because they are operating from a position of relative strength, public sector unions must be at the forefront of any effort to re-establish union influence in our society. With this ultimate objective in mind, the following priorities have been embraced by most of the major public sector unions: expand political action, enhance organizing programs, fight privatization, mobilize members in support of the above, and develop a new generation of leaders.
If public sector unions are successful in achieving these priorities, the entire labor movement will benefit. In the next section we present an optimistic scenario that outlines what we see as key ingredients if public sector unions are to prevail. Unfortunately, we are not fully convinced that this formula will be pursued with sufficient vigor to meet the political and economic challenges that threaten unions. Later in the paper we will describe a more pessimistic course of events that could result in gradual contraction of density and influence. Although we concur on the factors that could lead alternatively to success or failure, we differ on the weights we assign to the two scenarios. Co-author Pinnock believes that the evidence supports a positive prognostication, while co-author Hurd is less sanguine and leans towards the forecast of adversity (apropos his training as an economist). We are in agreement, however, on the essential elements of a revitalized labor movement and will conclude the paper with a synopsis of our prescription for productive transformation
A high-level semiotic trust agent scoring model for collaborative virtual organisations
In this paper, we describe how a semiotic ladder, together with a supportive trust agent, can be used to address “soft” trust issues in the context of collaborative Virtual Organisations (VO). The intention is to offer all parties better support for trust (as reputation) management including the reduction of risk and improved reliability of VO e-services. The semiotic ladder is intended to support the VO e-service lifecycle through the articulation of e-trust at various levels of system abstraction, including trust as measurable confidence. At the social level, reputation and reliability measures of e-trust are the relevant dimensions as regards choice of VO partner and are also relevant to the negotiation of service level agreements between the VO partners. By contrast, at the lower levels of the trust ladder, e-trust measures typically address the degree to which secure sign on and message level security conforms to various tangible technological security protocols. The novel trust agent provides the e-service consumer with an objective measure of the trustworthiness of the e-service at run-time, just prior to its actual consumption. Specifically, VO e-service consumer confidence level is informed, by leveraging third party objective evidence. This evidence comprises a set of Corporate Governance (CG) scores. These scores are used as a trust proxy for the "real" owner of the VO. There are also inherent limitations associated with the use of CG scores. These are duly acknowledged
Got Women? Hiring and Retaining Female Information Technology Professionals Through Effective Human Resource Marketing
The current pipeline for information technology (IT) professionals is dismal, with increasing jobs and decreasing applicants. We propose that one solution to this problem is encouraging women to pursue careers in IT. Today, women are underrepresented, and as a result, they comprise an untapped market segment. After discussing the current state of the industry, we propose that HR professionals should take a proactive, marketing approach to the recruitment and retention of women in the IT field. Lastly, we provide specific recommendations and discuss approaches taken by several companies to address this dilemma
Practical cryptographic strategies in the post-quantum era
We review new frontiers in information security technologies in
communications and distributed storage technologies with the use of classical,
quantum, hybrid classical-quantum, and post-quantum cryptography. We analyze
the current state-of-the-art, critical characteristics, development trends, and
limitations of these techniques for application in enterprise information
protection systems. An approach concerning the selection of practical
encryption technologies for enterprises with branched communication networks is
introduced.Comment: 5 pages, 2 figures; review pape
Domestic Outsourcing in the United States: A Research Agenda to Assess Trends and Effects on Job Quality
The goal of this paper is to develop a comprehensive research agenda to analyze trends in domestic outsourcing in the U.S. -- firms' use of contractors and independent contractors -- and its effects on job quality and inequality. In the process, we review definitions of outsourcing, the available scant empirical research, and limitations of existing data sources. We also summarize theories that attempt to explain why firms contract out for certain functions and assess their predictions about likely impacts on job quality. We then lay out in detail a major research initiative on domestic outsourcing, discussing the questions it should answer and providing a menu of research methodologies and potential data sources. Such a research investment will be a critical resource for policymakers and other stakeholders as they seek solutions to problems arising from the changing nature of work
