The Promise of Resistance: A New Lens for Climate Change Adaptation Research and Practice

ABSTRACTOver the years, thousands of climate change adaptation projects have been implemented globally. While there has been substantial scholarship on the extent and nature of adaptation efforts, fewer studies have examined why and how adaptation projects are being resisted. An analysis of resistance to adaptation offers critical insights to scholars and practitioners by recognizing the contentious nature of adaptation pathways and highlighting alternative visions for adaptation. Drawing on 20 case studies identified through a systematic review of the literature, we identify nine insights for research and practice. First, there is little literature on resistance to adaptation, suggesting that it is being underreported. Second, resistance to adaptation is not an anomaly, spanning sectors, actors, and geographies. Third, resistance to adaptation initiatives often has little to do with climate change skepticism. Fourth, the modes and outcomes of resistance are creative and diverse. Fifth, the state plays a critical, but not uniform, role in adaptation and thus resistance. Sixth, formal participation mechanisms can accommodate, neutralize, or facilitate resistance to adaptation. Seventh, the diverse goals of resistance reflect the multiplicity of imagined adaptation futures. Eighth, resistance is generative of material outcomes and novel subjectivities. Ninth, resistance can be costly, fracturing, and ineffective. This review highlights the need to further investigate resistance to climate change adaptation, which should be seen as a site of political struggle between different conceptions of what adaptation is and should be. It also provides insights for identifying maladaptation and pathways toward more emancipative forms of adaptation.

Factors Influencing the Implementation of the Hospital Management Information System on the Quality of Service

An information system serves as a formal mechanism that supplies management with precise and timely data essential for decision-making, facilitating successful planning, oversight, and operational functions. This research employs a quantitative methodology with a cross-sectional design. The research population comprises employees utilizing computer systems in units linked to SIiMRS, with a sample size of 125 individuals. This research indicates that human resources significantly influence the implementation of SIMRS on service quality at RSU Bethesda Gunungsitoli, with a p-value of 0.000, which is less than 0.05. The hardware significantly influences the implementation of SIMRS on service quality at RSU Bethesda Gunungsitoli, evidenced by a p-value of 0.001, which is less than 0.05. The implementation of software in SIMRS affects the quality of service at RSU Bethesda Gunungsitoli, evidenced by a p-value of 0.014, which is less than 0.05. Data management significantly influences the implementation of SIMRS on service quality at RSU Bethesda Gunungsitoli, evidenced by a p-value of 0.035, which is less than 0.05. The LAN conditions significantly influence the implementation of SIMRS on the quality of service at RSU Bethesda Gunungsitoli, evidenced by a p-value of 0.023, which is less than 0.05. The findings of the multivariate analysis indicated that human resource factors exerted the most significant impact on service quality at RSU Bethesda Gunungsitoli. The continuity variable is indicated as 7.807, signifying that respondents with proficient human resources possess a 7.807 likelihood of enhancing the quality of service at RSU Bethesda Gunungsitoli.

Accountability of Village Fund Management in the Perspective of Agency Theory

This study aims to determine how the role and understanding of village officials influence the accountability of village fund management. This study also wants to see agency problems in the accountability of village fund management. The results of this study are the role of village officials has a variable significance level of 0.03 0.05, which means that the role of village officials has a positive and significant effect on the accountability of village fund management. Furthermore, the understanding of village officials has a variable significance level of 0.02 0.05, which means that the understanding of village officials has a positive and significant effect on the accountability of village fund management. Based on the results of interviews with village officials, agency theory in village fund management is very important to ensure accountability and transparency or openness. The community as a principal must obtain clear information and have a role in supervision, while the village government as an agent is required to carry out its duties transparently and responsibly. With both formal and informal monitoring mechanisms in place, potential conflicts of interest and moral hazard issues can be minimised.

Management Control System Design and Innovation: A Systematic Literature Review

AbstractThe purpose of this study is to examine through a systematic review the management accounting research that focuses on the role of management control systems (MCS) in enhancing innovation within organizations. For that purpose, a total of 19 articles from publications spanning from 2000 to 2022 were selected using the keywords of management control system and innovation. The findings indicate that the Levers of Control (LoC) is the most widely studied topic. The next popular topic being examined is formal and informal control mechanisms. The aspect of innovation in that literature mainly focuses on product innovation, management and organizational innovation, and environmental innovation and sustainability. Future research can explore more the role of the MCS in the combined mechanism of LoC to encourage innovation. This paper contributes to the MCS literature by examining the suitable mechanisms affecting the success of innovation in a rapidly changing environment. Keywords:Management Control System, Innovation, Review Literature, Levers Of Control, New Product Development

Patient safety and quality improvement education in dermatology residency programs: a nationwide survey of program directors.

Patient Safety and Quality Improvement (PSQI) are key components of graduate medical training, as detailed by the Accreditation Council for Graduate Medical Education (ACGME), with specific requirements that residents participate in experiential learning in PSQI during residency training. This study aimed to analyze the breadth of available and required PSQI educational experiences across dermatology residency programs in the United States. The objective of this study was to characterize the scope of PSQI educational experiences across dermatology residency programs. We electronically surveyed program directors of all ACGME-accredited dermatology residency programs from September 2023 to March 2024. Responses to the survey were anonymously collected with Research Electronic Data Capture (REDCap). Of the 145 dermatology programs surveyed, 37 program directors responded (25.5%). 89.2% of programs reported requiring residents to participate in PSQI educational experiences, with the most common being participation in a resident-led QI project (70.3%), which was also the most commonly available experience (91.2%). The least common required experience was observed simulated patient safety events and analyses. 83.8% of programs reported formal mechanisms to assess residents' competency in QI. This study highlights variation in PSQI experiences within dermatology residency programs across the United States. More than 10% of surveyed programs reported no required QI experiences during residency training despite ACGME program requirements. Additional gaps include variation in assessment of resident PSQI competencies. This study provides insight on the current landscape of PSQI education across dermatology residency programs and identifies opportunities to strengthen dermatology programs' PSQI educational offerings.

Young carers in Ghana: caring activities, ways into care and the impacts of caregiving

ABSTRACT In Ghana, children often provide care and support to family members with disabilities, mental illnesses and other health conditions. Understanding the nature of their caring activities is essential for identifying stressors and promoting better health and wellbeing outcomes for this group of children, described in the wider literature as young carers. This qualitative study investigated the nature and impact of caring activities on young carers aged 11–17 years. The findings revealed that young carers provide domestic, financial, medical and personal care. Caring activities while beneficial, result in a double burden, as young carers often support both the care recipients and their dependents. Despite the challenges associated with caring activities, the study also reveals the myriad reasons young carers enter care work, suggesting that the work of young carers is not simply an obligation or a choice but a process and an integral part of Ghanian family structures. The study highlights the urgent need for formal mechanisms to identify and support young carers and their care recipients in Ghana.

Bystanders or active participants? Mobilising meaningful participation in River Basin management: lessons from the Gauteng Province, South Africa

ABSTRACT This paper explores the concept of meaningful participation in river basin management, using the case study of the Hennops River in Gauteng Province, South Africa. Experiences of different stakeholders and communities regarding their involvement in the management of the Hennops River basin are analysed following engagement through interviews, workshops and clean-up initiatives. Several barriers and enablers for meaningful participation, such as lack of awareness, capacity, coordination, trust and incentives, are identified. Some recommendations are proposed for improving stakeholder and community participation, based on the lessons learned from the case study. This includes the formulation of a social fund to support small community-based projects such as clean-up campaigns. Projects should be reflective, keeping the community engaged and active. The paper argues that meaningful participation requires not only formal mechanisms of engagement and decision-making but also informal and practical actions that empower stakeholders and communities to take ownership and responsibility for their water resources and environment. For meaningful participation to take place, more needs to be done to shift communities away from a ‘bystander’ position to a more active role. A new approach to community engagement is therefore necessary to support stakeholder-driven initiatives and the raising of awareness in poorer communities.

Implementation Dynamics and Project Delivery: A Case Study of Tullow Oil Exploration in Turkana, Kenya

Purpose: The purpose of the study was to investigate the effect of community stakeholder involvement in the implementation process on project delivery by the Tullow Oil Exploration Company in South Lokichar Basin in Turkana, Kenya. Methodology: The study utilized a descriptive research design that incorporated both qualitative and quantitative methods for data collection. While qualitative design was predominantly utilized, a small amount of quantitative methodology was included to assess perceptions. A triangulated methodological design was employed to ensure the accuracy and reliability of the data. The study involved the use of questionnaire method to collect quantitative data and key informants guide and focus group discussion to collect qualitative data. This research adopted multistage sampling utilizing cluster sampling as one of the sampling methods and the first stage of sampling, where villages were divided into clusters which were later randomly sampled based on their proximity to the oil wells. Two villages from Lokori / Kochodin Ward in Turkana South Sub-County and eight villages in Lokichar Ward in Turkana South Sub-County were randomly picked. Quantitative data was analyzed using descriptive analysis and inferential analysis (cross-tabulation with chi-square and binary logistic regression analyses) by use of SPSS version 25. Qualitative data was analysed based on Content Analysis (CA) method. Findings: The study revealed community stakeholder involvement in the implementation process had statistically significant effect on community project delivery by Tullow Oil Exploration Company in South Lokichar Basin in Turkana, Kenya (X2=8.161, df=1, p-value = .000 and p-value=.037 (<0.05 respectively). Unique Contribution to Theory, Practice and Policy: The Stakeholder Theory emphasizes the need for companies to take a wider view of their economic activities and consider all other stakeholders' interests, not just the shareholders. Its contributions to the descriptive, normative, and instrumental elements of Stakeholder Theory are thus underlined by the fact that community engagement may make or break the success and sustainability of community projects in this industry even during the implementation phase itself. It hence requires a balancing of the expectations of a Company with those of the community so that all the stakeholders really share goals and vision in similar ways concerning the community project at hand. The actual study indicates that, in practice, the effective participation of community stakeholders throughout the entire community project cycle-identification, planning, and especially implementation-enhances project delivery while at the same time enhancing ownership and cooperation at the local level. Such understanding of stakeholder management is key when companies operate their business in marginalized areas for the purpose of mitigating risks, community resistance, and ensuring easier ways of executing community projects. This research, therefore, calls for legal and regulatory environments that enhance stakeholder involvement in resource extraction projects. From a policy perspective, the government of Kenya and any other relevant country should develop policies that ensure that companies adopt formal mechanisms involving direct consultations of communities in the decision-making and operations processes. It is through this that the process reflects transparency, inclusiveness, and accountability-one of the facets of successful long-term community projects in resource-rich areas. These contributions are aimed at the improvement of project delivery in a sustainable manner together with social harmony across large-scale extraction-impacted areas.

Accounting for solidarity: trust and results as a replacement of contracts in water operators’ partnerships

ABSTRACT Water operators' partnerships (WOPs) differ from other types of collaborations in that they are ‘solidarity-based’. By focusing on two partnerships between utilities from the Netherlands and Malawi, this article examines how accountability is addressed in solidarity-based WOPs. The article finds that the solidarity-based nature of these partnerships makes accountability between partners through contractual arrangements challenging. In such a setting, multiple and diverse lines of accountability exist. In particular, trust appears to complement more formal accountability mechanisms. At the same time, this trust relationship is only possible as long as the partnerships produce the desired operational results. The cases furthermore suggest that rather than think about optimal accountability mechanisms, ensuring accountability mechanisms that are sufficient and accepted by both partners is already an achievement.

Living Dead: Trans Cooperations with Mad Necropolitics and the Mad Trans Coalitions that Might Replace Them.

Trans subjectivities continue to be included in major compendia of mental illness, despite recent moves to depathologize "cross-gender identification." Regardless, the inclusion of "gender dysphoria" is often framed as a formal mechanism to support access to gender affirming care as transgender subjectivities are re-conceptualized as part of sex/gender diversity and away from madness. The latter permits trans individuals to evade sanist oppressions. However, moves to disassociate from mad individuals also often serve to condone sanism. For instance, a contemporary policy landscape often sees transgender advocates arguing for the "medical necessity" of gender affirming care for gender dysphoria as a "recognized medical condition," thereby skirting the inclusion of gender dysphoria as a psychiatric condition and implying that gender dysphoria carries a special ontological status that separates it from madness (reified as "mental illness"). More though, this framework endorses material violences toward mad individuals that are often advanced via the workings of the state to consign marginalized constituents to death by withholding the means of life, i.e., necropolitics. In the following, I argue that trans disassociations from madness often endorses or assents to mad necropolitics. Drawing from Mbembe's (Necropolitics. Duke University Press, Durham, 2019) framework, I suggest that medicalizing trans narratives, despite being used to object to anti-trans laws in contemporary context, ideologically support mad "death worlds" organized through the U.S.A. welfare state and prison industrial complex. However, I also suggest alternative strategies, i.e., intersectional collaboration, that may uplift mad and/or trans communities.

Citizen liabilities for state-perpetrated injustices in non-democracies: toward a new authorisation account

ABSTRACT When states perpetrate injustices, do their individual citizens develop liabilities to repair such wrongdoings? Most existing accounts of citizens’ liabilities for state-perpetrated injustices, whilst applicable across certain democratic contexts, struggle to provide robust accounts of the grounds and nature of liabilities for citizens in non-democratic contexts. This problematically leaves a lacuna when it comes to the responsibilities and appropriate responses of citizens in these states. This article advances a distinctive two-pronged authorisation-based account applicable to non-democracies. Objective authorisers are individuals who derive presumptive benefits, are comparably better-off under, and can reliably influence the decision-making processes over the injustice perpetrated by the state. Subjective authorisers are citizens who autonomously endorse their state as credible interpreters and upholders of their aims in relation to the injustices in question. Both objective and subjective authorisers of the state in relation to particular injustices perpetrated, are liable to compensate, actively oppose, and commemorate the victims of state-perpetrated injustices. This account will be shown to be empirically applicable to a large number of minimally decent non-democratic states, where the political elite enjoy moderate popular support over their incorporation and reflection of citizen interests and preferences in their governance, despite the absence of formal democratic electoral mechanisms. This authorisation-based view differs from existing accounts oriented around complicity and participatory intentions, in better accounting for non-participants who are nevertheless intuitively liable for the actions of their authorised state, as well as circumventing structural shortcomings affecting complicity-centric accounts.

Unpacking “the surprise chain”: the governance of food security during the COVID-19 pandemic in Melbourne, Australia

AbstractFood systems are being affected by multiple shocks related to climate change, the COVID-19 pandemic and geopolitical events. Food prices and food insecurity are rising globally as a result, raising questions about the effective governance of food security during shocks. This paper critically examines the governance of food security in Melbourne, Australia during a major food system shock, the COVID-19 pandemic. It draws on document analysis and 34 stakeholder interviews with 41 participants from government, industry and civil society between May 2020 and March 2021. The paper examines the role of these actors in governance mechanisms for two important aspects of food system governance during the COVID-19 pandemic, continuity of food supply and delivery of emergency food relief. Clark et al.’s (2021) “governance engagement continuum” is used to show how civil society groups were excluded from these formal governance mechanisms, instead establishing their own spaces of “self-governance”. The resilience aims associated with these governance mechanisms are also analyzed using Zurek et al.’s (2022) “three R’s” (robustness, recovery and reorientation) framework. Our study highlights the significant role of food industry actors in the continuity of food supply and delivery of emergency food relief, and it shows the vulnerabilities of emergency food relief that depends on industry food “surpluses” as a model for addressing food insecurity during food system shocks. We conclude that greater government leadership is needed in the governance of food security during food system shocks, and in implementation of legislative and policy approaches that are grounded in the human right to food.

Menyelami Filosofi Lonto Leok: Persatuan dan Konsensus dalam Budaya Manggarai

Lonto Léok, a tradition from Manggarai, Indonesia, reflects a significant transformation in the context of unity and communal decisions. Originating from inter-tribal conflicts, this tradition has evolved into a symbol of family unity. In Lonto Léok, formal interaction mechanisms are led by a leader known as "Tu'a Golo," who serves as a facilitator and guides the deliberation process. There are three main stages in Lonto Léok: "caca" (unpack), "cica" (discuss), and "congko" (finalize), reflecting an intensive deliberation process to reach collective agreements. This research aims to elucidate the history, meaning, and mechanisms of Lonto Leok in Manggarai culture while highlighting issues that still need to be addressed. The author adopts a qualitative method based on literature review, interviews, and the author's direct experiences as data sources. The research findings reveal that the shift in the meaning of Lonto Léok from battle to family unity demonstrates cultural adaptability in the face of social change. Lonto Léok represents how the Manggarai community manages conflicts and achieves consensus through deliberation and agreement.

Study of integration processes in the pharmaceutical market in the context of the development of territorial pharmaceutical ecosystems

Introduction. The ecosystem approach to the organization of business processes in the pharmaceutical market meets the prevailing trends, so the growth index of e-commerce in the retail sector of medicines for 5 years amounted to 1.87. The market distribution sector of medicines in the Russian Federation is characterized by a shift in corporate governance towards marketing cooperation based on aggregation electronic trading platforms (AETPS). Development of territorial pharmaceutical ecosystems (TFE) As a new integrative tool for managing the pharmaceutical development – production – distribution cycle, in order to achieve the target model of PHARMA 2030 at the territorial level, it requires the development of regulatory mechanisms for managing the supply of medicines. Objective: characteristics of integration processes in the industrial, wholesale and retail sectors of the pharmaceutical market to assess the potential competitiveness of territorial pharmaceutical ecosystems. Material and methods. The primary data for the analysis were: volumes of wholesale commodity residues of medicines produced in the Ural Federal District (461 registration certificates; proprietary Price and Distribution Test data for 230 trade names of LP EMIS data 2021–2022; Alpharm data 2021–2022; Datainsight 2022. In the course of the study, a structural analysis of the pharmaceutical market, a functional analysis of participants in the pharmaceutical product chain, and a marketing analysis were carried out. Results. It was found that the dynamics of the AETP segment development corresponds to the outstripping growth of highly integrated platforms: the short-term growth index of 5-pl AETP (Uteca) is 164%, 4-pl (Eapteca) is 55%, 3pl-AETP (averaged) is 36.5%. The absence of formal mechanisms of regional protectionism for the sale of finished dosage forms of local manufacturers in the Ural Federal District has been revealed. We have obtained the results of evaluating the effect of ecosystem integration of certain types of pharmaceutical market participants. For manufacturers of medicinal products, it was determined that the median coefficient of penetration of the local assortment of medicinal products into the pharmaceutical market in the context of ATX groups of level 2 is 0.67, which indicates a significant diversification of the assortment portfolio and the possibility of its aggregation without a barrier of internal competition. In the wholesale drugs sector, the potential for saving margins on medicines has been identified when implementing the scenario of localization of supplies in production regions in low and medium-low price ranges (30 – 550 rubles/unit), varying between 53–67%. It was found that the median share of regional distribution in the Ural Federal District (in packages) is 20.72%. It has been established that the Ural Federal District is one of the leaders in terms of the share of omnichannel consumers in the pharmaceutical market (63%), which is a significant incentive for the integration of organizations in the retail sector of the pharmaceutical market into the ecosystem 5pl platform. Conclusion. Situational analysis of the morphology of cooperative interactions in the pharmaceutical market allowed us to identify the prerequisites for the formation of ecosystem-organized management structures in the pharmaceutical market system – territorial pharmaceutical ecosystems. We have systematized incentives for ecosystem determination of medicines supplies, and found that: an additional channel for the market distribution of the industrial range of medicicnes in the Urals is not associated with a barrier to internal competition of pharmaceutical plants; the inclusion of regional suppliers in TFE will allow to form additional competitiveness in the “buyer's market” in conditions of market dominance of federal suppliers; the omnichannel approach to the distribution of the retail range of TFE in pharmacy organizations has a high projected conversion rate. A detailed assessment of integration processes in certain sectors of the pharmaceutical market did not reveal critical barriers to the introduction of TFE.

Team-based care in specialist practice: a path to improved physician experience in British Columbia

BackgroundSpecialist physicians in the province of British Columbia commonly work on teams in acute care settings such as operating rooms or inpatient hospital units. However, while the implementation of team-based care (TBC) has been supported in primary care clinics, no formal mechanisms have supported specialist physicians in adopting TBC in their private outpatient offices. Adopting TBC models is associated with improving physician experience, efficiency, and patient experience.MethodsThe Institute for Healthcare Improvement Breakthrough Series guided a program to support 11 specialist physicians, representing nine different specialties, to develop and implement TBC in outpatient offices. Participants were supported through resources including funding, mentorship, and learning opportunities. To determine whether the program improved physician experience, quantitative data were collected using the validated Mini Z survey and qualitative data were collected through monthly reports, semi-structured interviews, and focus groups. Patient experience data were collected through surveys and follow-up calls.ResultsThe fifteen-month program was successful, with 10 of the 11 specialists implementing TBC in their offices. The Mini Z results demonstrated that physician experience improved over the course of the program, with scores on job satisfaction, work pace, and time spent on the electronic medical record improving the most. Interviews with specialists and focus groups with specialists’ team members support these findings, with participants stating that TBC modulates workloads, begins to affect burnout, improves work-life balance, and increases the efficiency of care. Patients reported positive experiences while receiving TBC. Patients were less likely to visit the emergency department after consultations with specialist teams, and providers agreed that their patients would be less likely to seek acute care because of the new practice models.ConclusionTBC is a viable model for specialist physicians and their health care teams practicing in British Columbia to foster well-being, job satisfaction, and efficiency, and to improve patient experience. These findings may be of interest to specialists, health care providers, policymakers, and administrators looking to better support and retain specialist practices that are integral to patient care.

Education and Training in Global Neurosurgery: The Quest for Diversity and Equitable Collaborations.

Education and training are essential components of global neurosurgery because they provide a sustainable solution to address the workforce deficits in the neurosurgical burden of disease. Neurosurgery training programs and opportunities exist in most areas of the world, but some countries still lack formal mechanisms to train future generations. In this special article, we review the neurosurgical workforce deficit, characterize factors influencing the absence or inadequacy of neurosurgical training, and identify strategies that could facilitate global efforts in building a stronger workforce. We summarize the key neurosurgical training models worldwide and the factors influencing the standardization of neurosurgical education by region. In addition, we evaluate the "brain drain" issue in the larger context of the healthcare workforce and propose solutions to mitigate this phenomenon in neurosurgical practice. Future generations of neurosurgical trainees depend on our efforts to intensify and expand education and training in this new virtual era. As we look to the future, we must prioritize education to strengthen the future neurosurgeons who will lead and shape the frontiers of our field.

Drivers’ Knowledge, Attitude and Practices Towards Traffic Rules and Regulations

Research frequently reports that the majority of crashes (up to 80%), are the fault of drivers. Further, the WHO reports that most fatal crashes occur in low- and middle-income countries (LMIC). In LMIC, including Pakistan, most drivers have low levels of knowledge about traffic rules and regulations, have negative attitudes towards rules and regulations and often violate road safety rules. This study used a structured survey of drivers in Karachi, Pakistan (n=260). Most respondents were aware that helmet use for motorbike riders is compulsory (74.6%), agreed it was important to follow road signs (74.2%) and wear a seat belt (64.6%). However, over half did not know the speed limit in residential areas (54.6%) and almost half considered drug use when driving was not dangerous or were against the penalty or fine for violation of traffic laws (45.4%). In addition, 45.8% of all drivers thought driving licenses were unnecessary. This study suggests there may be low levels of driver knowledge of certain road rules (e.g. speed limit), negative attitudes about certain safe driving practices (drug driving), and low levels of value placed on driving license in Karachi, Pakistan. Analysis suggest that knowledge and attitude affect driver practices in Karachi, Pakistan. Strengthening enforcement and related public communication measures about traffic rules and greater penalties that are sufficiently deterring for the violators of the traffic rules is needed. There must also be a formal mechanism to issue the driving licence after a proper test of the knowledge of road rules and driving following those rules.

Open strategy and the multinational firm

PurposeDistance has been a core concept and issue in international business and management research. While scholars argue that distance through internationalization is increasing costs, distance is also associated with positive implications such as the integration of more diverse knowledge. Still, many firms struggle to manage distance effectively and efficiently in their multinational contexts. The purpose of this study therefore is to propose Open Strategy – increasing transparency and inclusion in the strategy process – as an attractive concept for managing distance.Design/methodology/approachThis is a conceptual paper where the authors introduce Open Strategy to the IB community.FindingsThe authors argue that opening the strategy of multinational enterprises, enables firms to leverage diversity by re-combining the firms diverse and distant knowledge. It also reduces distance by moving beyond formal mechanisms of control and coordination to improve joint understanding, cooperative commitment and strategy implementation. The framework shows how firms can move beyond established dogmas in international business research by rendering their strategy processes more open.Originality/valueLeveraging the Open Strategy literature, the authors are able to find a way to respond to the challenge of increasing distance, in fact even arguing that distance can be beneficial if framed as diversity.

QACDes: QoS-aware context-sensitive design of cyber-physical systems

There is a lot of confusion and ambiguity regarding the quantification of the Quality of Service (QoS) of a system, especially for cyber-physical systems (CPS) involved in automating or controlling the operations in built environments and critical urban infrastructures, such as office buildings, factories, transportation systems, smart cities, etc. In these cases, the QoS, as experienced by human users, depends on the context in which they (i.e., humans) interact with these systems. Traditionally, the QoS of a CPS has been defined in terms of absolute metrics. Such measures are unable to take into account the variations in performance due to contextual factors arising out of different kinds of human interactions. Further, the QoS of a CPS has typically been evaluated by comparing the performance of the actual, fully realized system with the given QoS constraints only after the actual system has been completely developed. In the case of faults in the design exposed by observed deviations from the QoS constraints due to unpredicted variations in the contextual factors, the system needs to be re-designed and re-developed from scratch. Due to the above-mentioned reason, the validation approach associated with the traditional QoS makes the design of CPS systems prohibitively expensive, impractical, as well as infeasible in numerous application areas, such as civil and engineering works, since it may not be possible to modify the system once developed beyond a certain extent. To that end, we propose a context-aware definition of QoS of a CPS which facilitates the design of robust systems as elaborated below. In this paper, we define QoS as a function of contextual factors. A CPS designed according to our QoS specifications would always satisfy the QoS irrespective of any possible changes in contextual factors resulting from many different human interactions that may occur during operation of the system. We also present QACDes - a novel framework that provides a formal mechanism for validating the design of a CPS with respect to the specified QoS constraints at the design phase as well as after the realization of the actual system. QACDes can validate any given CPS, irrespective of its application domain, against a QoS guarantee: (A) as early as even before the design phase by comparing the proposed model with a baseline model, or (B) after the realization of the actual system based on logs collected from running the actual system. We consider a lighting control system that manages the light switches - switching it on/off depending on contextual factors, such as the presence of occupants and time of the day. Using the lighting control system in a building as a use case, we analyze and demonstrate the effectiveness of our QoS definition as well as the QACDes framework against the performance metric measured in an actual fully-realized CPS.
