Future OE Mission Command and Future OE Decision Cycles
Enormous commercial, academic, and governmental resources are being expended to build machines which can autonomously assist humans in a variety of complex tasks (e.g., drive cars, fly aircraft, engage targets, manage distributed operations). This post asserts that the technologies being developed and deployed by these efforts will eventually force future mission command capabilities to include abilities to detect, analyze, and react to man-machine interface deception / surprise events at all echelons of command. The need for these new / improved decision support capabilities will be driven by the challenges of creating accurate Intelligence, Surveillance, and Reconnaissance (ISR) estimates while encountering increased deception / surprise technologies. These deception technologies are appearing at every echelon of mission command and are being driven, in part, by the ongoing commercial integration of the international network of Information Technology (IT) systems and the international network of Operational Technology (OT) systems. A lesson learned from the use of the Stuxnet malware to cause Iranian centrifuges to self-destruct is that malware can be used to achieve tactical surprise of human operators. The centrifuge control man-machine interface was exploited to deceive human operators concerning the true state of the autonomous control system as the machines were being commanded to destroy themselves. The Iranian operators were unaware for a lengthy period that they were being deceived by their monitoring software and they were surprised when they discovered the extent of the damage to the centrifuges. The centrifuge-control, man-machine interface was informing the human operators that everything was proceeding as commanded when in fact the machines were shaking themselves apart. It is apparent from many recent events/results that similar outcomes are now possible at each echelon of command (individual deception outcomes at the âtip of the spear,â as well as tactical surprise outcomes, operational surprise outcomes, and strategic surprise outcomes). This note provides a summary of some results in achieving distributed state estimation and control of complex, networked systems. This post asserts that a wide variety of distributed control systems, including national infrastructure systems and possibly military command and control systems are subject to deliberate and inadvertent cyber and physical anomalies (failure modes) and states the authorâs opinions regarding the implications of the ongoing integration of IT and OT for future Mission Command decisions and future Operational Environment (OE) state estimation results
A safer place for patients: learning to improve patient safety
1 Every day over one million people are treated
successfully by National Health Service (NHS) acute,
ambulance and mental health trusts. However, healthcare
relies on a range of complex interactions of people,
skills, technologies and drugs, and sometimes things do
go wrong. For most countries, patient safety is now the
key issue in healthcare quality and risk management.
The Department of Health (the Department) estimates
that one in ten patients admitted to NHS hospitals will be
unintentionally harmed, a rate similar to other developed
countries. Around 50 per cent of these patient safety
incidentsa could have been avoided, if only lessons from
previous incidents had been learned.
2
There are numerous stakeholders with a role in
keeping patients safe in the NHS, many of whom require
trusts to report details of patient safety incidents and near
misses to them (Figure 2). However, a number of previous
National Audit Office reports have highlighted concerns
that the NHS has limited information on the extent and
impact of clinical and non-clinical incidents and trusts need
to learn from these incidents and share good practice across
the NHS more effectively (Appendix 1).
3 In 2000, the Chief Medical Officerâs report An
organisation with a memory
1
, identified that the key
barriers to reducing the number of patient safety incidents
were an organisational culture that inhibited reporting and
the lack of a cohesive national system for identifying and
sharing lessons learnt.
4 In response, the Department published Building a
safer NHS for patients3 detailing plans and a timetable
for promoting patient safety. The goal was to encourage
improvements in reporting and learning through the
development of a new mandatory national reporting
scheme for patient safety incidents and near misses. Central
to the plan was establishing the National Patient Safety
Agency to improve patient safety by reducing the risk of
harm through error. The National Patient Safety Agency was
expected to: collect and analyse information; assimilate
other safety-related information from a variety of existing
reporting systems; learn lessons and produce solutions.
5 We therefore examined whether the NHS has
been successful in improving the patient safety culture,
encouraging reporting and learning from patient safety
incidents. Key parts of our approach were a census of
267 NHS acute, ambulance and mental health trusts in
Autumn 2004, followed by a re-survey in August 2005
and an omnibus survey of patients (Appendix 2). We also
reviewed practices in other industries (Appendix 3) and
international healthcare systems (Appendix 4), and the
National Patient Safety Agencyâs progress in developing its
National Reporting and Learning System (Appendix 5) and
other related activities (Appendix 6).
6 An organisation with a memory1
was an important
milestone in the NHSâs patient safety agenda and marked
the drive to improve reporting and learning. At the
local level the vast majority of trusts have developed a
predominantly open and fair reporting culture but with
pockets of blame and scope to improve their strategies for
sharing good practice. Indeed in our re-survey we found
that local performance had continued to improve with more
trusts reporting having an open and fair reporting culture,
more trusts with open reporting systems and improvements
in perceptions of the levels of under-reporting. At the
national level, progress on developing the national reporting
system for learning has been slower than set out in the
Departmentâs strategy of 2001
3
and there is a need to
improve evaluation and sharing of lessons and solutions by
all organisations with a stake in patient safety. There is also
no clear system for monitoring that lessons are learned at the
local level. Specifically:
a The safety culture within trusts is improving, driven
largely by the Departmentâs clinical governance
initiative
4
and the development of more effective risk
management systems in response to incentives under
initiatives such as the NHS Litigation Authorityâs
Clinical Negligence Scheme for Trusts (Appendix 7).
However, trusts are still predominantly reactive in
their response to patient safety issues and parts of
some organisations still operate a blame culture.
b All trusts have established effective reporting systems
at the local level, although under-reporting remains
a problem within some groups of staff, types of
incidents and near misses. The National Patient Safety
Agency did not develop and roll out the National
Reporting and Learning System by December 2002
as originally envisaged. All trusts were linked to the
system by 31 December 2004. By August 2005, at
least 35 trusts still had not submitted any data to the
National Reporting and Learning System.
c Most trusts pointed to specific improvements
derived from lessons learnt from their local incident
reporting systems, but these are still not widely
promulgated, either within or between trusts.
The National Patient Safety Agency has provided
only limited feedback to trusts of evidence-based
solutions or actions derived from the national
reporting system. It published its first feedback report
from the Patient Safety Observatory in July 2005
Entering and leaving employment in deprived neighbourhoods undergoing area regeneration
Concentrations of worklessness have been persistent in the UK for several decades but have not been tackled effectively by policy. An individualised approach to unemployment has existed, alongside employment policies without a strong geographical component. A reliance on area-based regeneration programmes has shifted from a property-led to a holistic approach, with the potential to address a range of factors associated with employment. To gauge the effectiveness and appropriateness of holistic area regeneration, this paper uses longitudinal survey data to examine movements into and out of employment for people living in deprived areas of Glasgow with concentrated worklessness and subject to area regeneration. There were modest net gains to employment over time in the study areas, and such gains were positively associated with traditional elements of regeneration such as housing improvements and community empowerment. However, other components of regeneration assumed to aid employment, such as social networks and participation in training, were found to have no effect. Other factors that were associated both with entering or leaving employment feature less frequently within regeneration programmes and require more integration into future approaches, particularly increasing physical activity among populations, helping people cope with physical and mental health issues, and improving transport and mobility
Future-proofing the state: managing risks, responding to crises and building resilience
Summary: This book focuses on the challenges facing governments and communities in preparing for and responding to major crises â especially the hard to predict yet unavoidable natural disasters ranging from earthquakes and tsunamis to floods and bushfires, as well as pandemics and global economic crises.
Future-proofing the state and our societies involves decision-makers developing capacities to learn from recent âdisasterâ experiences in order to be better placed to anticipate and prepare for foreseeable challenges. To undertake such futureproofing means taking long-term (and often recurring) problems seriously, managing risks appropriately, investing in preparedness, prevention and mitigation, reducing future vulnerability, building resilience in communities and institutions, and cultivating astute leadership. In the past we have often heard calls for âbetter future-proofingâ in the aftermath of disasters, but then neglected the imperatives of the message.
Future-Proofing the State is organised around four key themes: how can we better predict and manage the future; how can we transform the short-term thinking shaped by our political cycles into more effective long-term planning; how can we build learning into our preparations for future policies and management; and how can we successfully build trust and community resilience to meet future challenges more adequately
Learning or leaving? An international qualitative study of factors affecting the resilience of female family doctors
Background: Many countries have insufficient numbers of family doctors, and more females than males leave the workforce at a younger age or have difficulty sustaining careers. Understanding the differing attitudes, pressures, and perceptions between genders toward their medical occupation is important to minimise workforce attrition. Aim: To explore factors influencing the resilience of female family doctors during lifecycle transitions. Design & setting: International qualitative study with female family doctors from all world regions. Method: Twenty semi-structured online Skype interviews, followed by three focus groups to develop recommendations. Data were transcribed and analysed using applied framework analysis. Results: Interview participants described a complex interface between competing demands, expectations of their gender, and internalised expectations of themselves. Systemic barriers, such as lack of flexible working, excessive workload, and the cumulative impacts of unrealistic expectations impaired the ability to fully contribute in the workplace. At the individual level, resilience related to: the ability to make choices; previous experiences that had encouraged self-confidence; effective engagement to obtain support; and the ability to handle negative experiences. External support, such as strong personal networks, and an adaptive work setting and organisation or system maximised intervieweesâ professional contributions. Conclusion: On an international scale, female family doctors experience similar pressures from competing demands during lifecycle transitions; some of which relate to expectations of the female's âroleâ in society, particularly around the additional personal pressures of caring commitments. Such situations could be predicted, planned for, and mitigated with explicit support mechanisms and availability of workplace choices. Healthcare organisations and systems around the world should recognise this need and implement recommendations to help reduce workforce losses. These findings are likely to be of interest to all health professional staff of any gender
A Comprehensive Survey on Rare Event Prediction
Rare event prediction involves identifying and forecasting events with a low
probability using machine learning and data analysis. Due to the imbalanced
data distributions, where the frequency of common events vastly outweighs that
of rare events, it requires using specialized methods within each step of the
machine learning pipeline, i.e., from data processing to algorithms to
evaluation protocols. Predicting the occurrences of rare events is important
for real-world applications, such as Industry 4.0, and is an active research
area in statistical and machine learning. This paper comprehensively reviews
the current approaches for rare event prediction along four dimensions: rare
event data, data processing, algorithmic approaches, and evaluation approaches.
Specifically, we consider 73 datasets from different modalities (i.e.,
numerical, image, text, and audio), four major categories of data processing,
five major algorithmic groupings, and two broader evaluation approaches. This
paper aims to identify gaps in the current literature and highlight the
challenges of predicting rare events. It also suggests potential research
directions, which can help guide practitioners and researchers.Comment: 44 page
Decision Science Perspectives on Hurricane Vulnerability: Evidence from the 2010â2012 Atlantic Hurricane Seasons
Although the field has seen great advances in hurricane prediction and response, the economic toll from hurricanes on U.S. communities continues to rise. We present data from Hurricanes Earl (2010), Irene (2011), Isaac (2012), and Sandy (2012) to show that individual and household decisions contribute to this vulnerability. From phone surveys of residents in communities threatened by impending hurricanes, we identify five decision biases or obstacles that interfere with residentsâ ability to protect themselves and minimize property damage: (1) temporal and spatial myopia, (2) poor mental models of storm risk, (3) gaps between objective and subjective probability estimates, (4) prior storm experience, and (5) social factors. We then discuss ways to encourage better decision making and reduce the economic and emotional impacts of hurricanes, using tools such as decision defaults (requiring residents to opt out of precautions rather than opt in) and tailoring internet-based forecast information so that it is local, specific, and emphasizes impacts rather than probability
Timely and reliable evaluation of the effects of interventions: a framework for adaptive meta-analysis (FAME)
Most systematic reviews are retrospective and use aggregate data AD) from publications, meaning they can be unreliable, lag behind therapeutic developments and fail to influence ongoing or new trials. Commonly, the potential influence of unpublished or ongoing trials is overlooked when interpreting results, or determining the value of
updating the meta-analysis or need to collect individual participant data (IPD). Therefore, we developed a Framework for Adaptive Metaanalysis (FAME) to determine prospectively the earliest opportunity for reliable AD meta-analysis. We illustrate FAME using two systematic reviews in men with metastatic (M1) and non-metastatic (M0)hormone-sensitive prostate cancer (HSPC)
