Purpose The purpose of this paper is to perform large-scale environmental sensing with a lot of Internet of Things (IoT) devices, as typically seen in a Smart City, efficiently and for multiple applications. In this paper, we propose a novel sensing method, called mission-oriented sensing, which accepts multiple and dynamic sensing purposes on a single infrastructure. Design/methodology/approach The proposed method achieves the purpose by dealing sensing configuration (application’s purpose) as a mission. It realizes sharing single infrastructure by accepting multiple missions in parallel, and it accepts missions’ update anytime. In addition, the sensing platform based on military analogy can command and control a lot of IoT devices in good order, and this realizes mission-oriented sensing above. Findings Introducing mission-oriented sensing, multiple purpose large-scale sensing can be conducted efficiently. The experimental evaluation with a prototype platform shows the practical feasibility. In addition, the result shows that it is effective to update sensing configuration dynamically. Research limitations/implications The proposed method focuses aggregating environmental sensor value from a lot of devices, and, thus, it can treat stream data, such as video or audio or control a specific device directly. Originality/value In proposed method, a single-sensing infrastructure can be used by multiple applications, and it admits heterogeneous devices in a single infrastructure. In addition, the proposed method has less technical restriction and developers can implement actual platform with technologies for context.

Purpose The National Disability Insurance Scheme (NDIS) is a new program for the provision of support to people with disabilities in Australia. The purpose of this paper is to explore the early implementation experience of this scheme, with a particular focus on the implications of this scheme for issues of care integration. Design/methodology/approach Semi-structured interviews were conducted with 26 policymakers in the Commonwealth government charged with the design and implementation of the NDIS. Findings The authors find somewhat of a lack of clarity concerning the boundaries of the NDIS and how it will work with a range of different services in the provision of seamless and consumer-directed care. Many of the same kinds of debates about interfaces with services were detected in this study as have been highlighted in relation to UK individual funding schemes. If the NDIS is truly to support individuals with disabilities to achieve choice and control, important work will need to be undertaken in to overcome organizational and institutional boundaries. Originality/value There is little empirical data relating to the implementation of the NDIS to date. This is the first study to explore boundary issues in relation to care integration.

Emerging hybrid threats in large-scale warfare systems require networked teams to perform in a reliable manner under changing mission tactics and reconfiguration of mission tasks and force resources. In this paper, a formal Command and Control (C2) structure is presented that allows for computer-aided execution of the networked team decision-making process, real-time tactic selection, and reliable mission reconfiguration. A mathematically justified networked computing environment is provided called the Augmented Discrete Event Control (ADEC) framework. ADEC is portable and has the ability to provide logical connectivity among all team participants including mission commander, field commanders, war-fighters, and robotic platforms. The proposed C2 structure is developed and demonstrated on a simulation study involving Singapore Armed Forces team with three realistic symmetrical, asymmetrical, and hybrid attack missions. Extensive simulation results show that the tasks and resources of multiple missions are fairly sequenced, mission tactics are correctly selected, and missions and resources are reliably reconfigured in real time.

Purpose – The purpose of this paper is to seek to shed light on the practice of incomplete corporate disclosure of quantitative Greenhouse gas (GHG) emissions and investigates whether external stakeholder pressure influences the existence, and separately, the completeness of voluntary GHG emissions disclosures by 431 European companies. Design/methodology/approach – A classification of reporting completeness is developed with respect to the scope, type and reporting boundary of GHG emissions based on the guidelines of the GHG Protocol, Global Reporting Initiative and the Carbon Disclosure Project. Logistic regression analysis is applied to examine whether proxies for exposure to climate change concerns from different stakeholder groups influence the existence and/or completeness of quantitative GHG emissions disclosure. Findings – From 2005 to 2009, on average only 15 percent of companies that disclose GHG emissions report them in a manner that the authors consider complete. Results of regression analyses suggest that external stakeholder pressure is a determinant of the existence but not the completeness of emissions disclosure. Findings are consistent with stakeholder theory arguments that companies respond to external stakeholder pressure to report GHG emissions, but also with legitimacy theory claims that firms can use carbon disclosure, in this case the incomplete reporting of emissions, as a symbolic act to address legitimacy exposures. Practical implications – Bringing corporate GHG emissions disclosure in line with recommended guidelines will require either more direct stakeholder pressure or, perhaps, a mandated disclosure regime. In the meantime, users of the data will need to carefully consider the relevance of the reported data and develop the necessary competencies to detect and control for its incompleteness. A more troubling concern is that stakeholders may instead grow to accept less than complete disclosure. Originality/value – The paper represents the first large-scale empirical study into the completeness of companies’ disclosure of quantitative GHG emissions and is the first to analyze these disclosures in the context of stakeholder pressure and its relation to legitimation.

Purpose The purpose of this paper is to focus on the enterprise lending and control process in closely held banks, with special reference to Sri Lanka. It explores how those processes are being influenced by the distinctive cultural and political processes at organizational and societal levels. Design/methodology/approach The study relies on three cases built upon the life experiences of several employees in a closely held bank, articulating multiple sources of evidence: interviews, observations, documents, archival records, open-ended questionnaires, internet conversations and exchange of e-mails. The data analysis adopts cultural political economy theory. Findings The study’s findings reveal how cultural and political factors, such as egoistic motives and politics, gifts/rewards and a manipulative culture, along with exploitative and discriminatory politics at organizational and societal levels, articulate into the enterprise lending and control process (“five Cs”) in closely held banks. “Rational” enterprise lending and control processes in this context merely become a “ceremonial” practice, serving the petty interest of powerful capitalist business owners. Whereas previous studies emphasize that the criteria (five Cs) discriminate against ordinary people, as distinct from the élite, the findings of this study implicate that over and above that the criteria are set aside when it suits in order to favor or accommodate the élite. Originality/value The paper provides a “qualitative inquiry” on how cultural politics at organizational and societal-level effect on enterprise lending and control process within closely held banks in less developed countries (LDCs). The previous studies on bank lending and control used either large-scale surveys or alternatively devoted their interest toward the role and impact of accounting in World Bank and IMF-led lending schemes and policies, particularly in LDCs.

Software attacks like worm, botnet, and DDoS are the increasingly serious problems in IoT, which had caused large-scale cyber attack and even breakdown of important information infrastructure. Software measurement and attestation are general methods to detect software integrity and their executing states in IoT. However, they cannot resist TOCTOU attack due to their static features and seldom verify correctness of control flow integrity. In this paper, we propose a novel and practical scheme for software trusted execution based on lightweight trust. Our scheme RIPTE combines dynamic measurement and control flow integrity with PUF device binding key. Through encrypting return address of program function by PUF key, RIPTE can protect software integrity at runtime on IoT device, enabling to prevent the code reuse attacks. The results of our prototype’s experiment show that it only increases a small size TCB and has a tiny overhead in IoT devices under the constraint on function calling. In sum, RIPTE is secure and efficient in IoT device protection at runtime.

Interference in Wireless Sensor Network (WSN) predominantly affects the performance of the WSN. Energy consumption in WSN is one of the greatest concerns in the current generation. This work presents an approach for interference measurement and interference mitigation in point to point network. The nodes are distributed in the network and interference is measured by grouping the nodes in the region of a specific diameter. Hence this approach is scalable and isextended to large scale WSN. Interference is measured in two stages. In the first stage, interference is overcome by allocating time slots to the node stations in Time Division Multiple Access (TDMA) fashion. The node area is split into larger regions and smaller regions. The time slots are allocated to smaller regions in TDMA fashion. A TDMA based time slot allocation algorithm is proposed in this paper to enable reuse of timeslots with minimal interference between smaller regions. In the second stage, the network density and control parameter is introduced to reduce interference in a minor level within smaller node regions. The algorithm issimulated and the system is tested with varying control parameter. The node-level interference and the energy dissipation at nodes are captured by varying the node density of the network. The results indicate that the proposed approach measures the interference and mitigates with minimal energy consumption at nodes and with less overhead transmission.

Today, more than forty countries of the world are engaged in the development of military-purpose robots. A number of unique mobile robots with a wide range of capabilities are already being used by combat and intelligence units of the Armed forces of the developed world countries to conduct battlefield intelligence and support tactical groups. At present, the issue of using the latest information technology in the field of military robotics is thoroughly investigated, and the creation of highly effective information management systems in the land-mobile robotic complexes has acquired a new phase associated with the use of distributed information and sensory systems and consists in the transition from application of separate sensors and devices to the construction of modular information subsystems, which provide the availability of various data sources and complex methods of information processing. The purpose of the article is to investigate the ways to increase the autonomy of the land-mobile robotic complexes using in a non-deterministic conditions of modern combat. Relevance of researches is connected with the necessity of creation of highly effective information and control systems in the perspective robotic means for the needs of Land Forces of Ukraine. The development of the Armed Forces of Ukraine management system based on the criteria adopted by the EU and NATO member states is one of the main directions of increasing the effectiveness of the use of forces (forces), which involves achieving the principles and standards necessary for Ukraine to become a member of the EU and NATO. The inherent features of achieving these criteria will be the transition to a reduction of tasks of the combined-arms units and the large-scale use of high-precision weapons and land remote-controlled robotic devices. According to the views of the leading specialists in the field of robotics, the automation of information subsystems and components of the land-mobile robotic complexes can increase safety, reliability, error-tolerance and the effectiveness of the use of robotic means by standardizing the necessary actions with minimal human intervention, that is, a significant increase in the autonomy of the land-mobile robotic complexes for the needs of Land Forces of Ukraine.

PurposeThe purpose of this study is to empirically investigate determinants of financial distress among small and medium-sized enterprises (SMEs) during the global financial crisis and post-crisis periods.Design/methodology/approachSeveral statistical methods, including multiple binary logistic regression, were used to analyse a longitudinal cross-sectional panel data set of 3,865 Swedish SMEs operating in five industries over the 2008–2015 period.FindingsThe results suggest that financial distress is influenced by macroeconomic conditions (i.e. the global financial crisis) and, in particular, by various firm-specific characteristics (i.e. performance, financial leverage and financial distress in previous year). However, firm size and industry affiliation have no significant relationship with financial distress.Research limitationsDue to data availability, this study is limited to a sample of Swedish SMEs in five industries covering eight years. Further research could examine the generalizability of these findings by investigating other firms operating in other industries and other countries.Originality/valueThis study is the first to examine determinants of financial distress among SMEs operating in Sweden using data from a large-scale longitudinal cross-sectional database.
