Regulating autonomous agents facing conflicting objectives : a command and control example

UK military commanders have a degree of devolved decision authority delegated from command and control (C2) regulators, and they are trained and expected to act rationally and accountably. Therefore from a Bayesian perspective they should be subjective expected utility maximizers. In fact they largely appear to be so. However when current tactical objectives conflict with broader campaign objective there is a strong risk that fielded commanders will lose rationality and coherence. By systematically analysing the geometry of their expected utilities, arising from a utility function with two attributes, we demonstrate in this paper that even when a remote C2 regulator can predict only the likely broad shape of her agents' marginal utility functions it is still often possible for her to identify robustly those settings where the commander is at risk of making inappropriate decisions

Spacecraft command verification: The AI solution

Recently, a knowledge-based approach was used to develop a system called the Command Constraint Checker (CCC) for TRW. CCC was created to automate the process of verifying spacecraft command sequences. To check command files by hand for timing and sequencing errors is a time-consuming and error-prone task. Conventional software solutions were rejected when it was estimated that it would require 36 man-months to build an automated tool to check constraints by conventional methods. Using rule-based representation to model the various timing and sequencing constraints of the spacecraft, CCC was developed and tested in only three months. By applying artificial intelligence techniques, CCC designers were able to demonstrate the viability of AI as a tool to transform difficult problems into easily managed tasks. The design considerations used in developing CCC are discussed and the potential impact of this system on future satellite programs is examined

The experience of facilitators and participants of long term condition self-management group programmes: a qualitative synthesis

Objective: Our aim was to systematically review the qualitative literature about the experiences of both facilitators and participants in a range of group-based programmes to support the self-management of long-term conditions. Methods: We searched 7 databases using the terms ‘self-management’, ‘group’ and ‘qualitative’. Full text articles meeting the inclusion criteria were retrieved for review. A thematic synthesis approach was used to analyse the studies. Results: 2126 articles were identified and 24 were included for review. Group participants valued being with similar others and perceived peer support benefits. Facilitators (HCP and lay) had limited group specific training, were uncertain of purpose and prioritised education and medical conformity over supportive group processes and the promotion of self-management agency and engagement. Overall, studies prioritised positive descriptions. Conclusion: Group programmes’ medical self-management focus may reduce their ability to contribute to patient-valued outcomes. Further research is needed to explore this disconnect. Practice implications: This review supports broadening the scope of group-based programmes to foreground shared learning, social support and development of agency. It is of relevance to developers and facilitators of group self-management programmes and their ability to address the burden of long-term conditions

How do facilitators of group programmes for long-term conditions conceptualise self-management support?

Objectives: Increasing self-management skills in people with long-term conditions is widely advocated in policies and guidelines. Group programmes are a common format; yet, how self-management support objectives are enacted in their delivery is poorly understood. Our aim is to explore the perspectives of group programme facilitators. Methods: We undertook thematic analysis of transcribed data from in-depth semi-structured interviews with health professional facilitators (n = 13) from six diverse self-management support group programmes (of obesity, diabetes and chronic obstructive pulmonary disease). Results: Facilitators viewed group programmes as responses to health system pressures, e.g. high patient demand. They focussed on providing in-depth education and instruction on physical health, risks and lifestyle behaviour change and emphasised self-responsibility for behaviour change whilst minimising goal setting and support amongst group participants. There were tensions between facilitators’ professional identity and group leader role

Education Maintenance Allowance : the first two years : a quantitative evaluation

The Department for Education and Skills (DfES) has commissioned a longitudinal evaluation of the piloting of Education Maintenance Allowances (EMAs). The evaluation is being undertaken by a consortium of research organisations, led by the Centre for Research in Social Policy (CRSP) and also includes the National Centre for Social Research, the Institute for Fiscal Studies (IFS) and the Institute for Employment Research (IER). This is the second report of the statistical evaluation of EMA. The statistical evaluation design is a longitudinal cohort study involving large random sample surveys of young people (and their parents) in 10 EMA pilot areas and eleven control areas. Two cohorts of young people were selected from Child Benefit records. The first cohort of young people left compulsory schooling in the summer of 1999 and they, and their parents, were interviewed between November 1999 and April 2000. A second interview was carried out with these young people between November 2000 and April 2001. The second cohort left compulsory education the following summer of 2000 and young people, and their parents, were first interviewed between November 2000 and April 2001

Working with Natural Helpers: a Handbook for Social Workers

The practicum consists of a study of methods of identifying and working with natural caregivers, based on previous descriptions in the literature of natural caregivers and their networks, presented in handbook format, and addressed to social service delivery people. Most of the natural helping literature describes natural helpers and natural helping networks, Little is available about the worker - helper relationship itself, about how to find natural helpers, and about how to develop and maintain relationships with them. It is this relationship between the worker and the natural helper that we studied and about which we have written

Retreating to nature : rethinking 'therapeutic landscapes'

There is a long history of removing oneself from ‘society’ in order to recuperate or repair. This paper considers a yoga and massage retreat in Southern Spain, and what opportunities this retreat experience might offer for recuperation and the creation of healthy bodies. The paper positions ‘nature’ as an active participant, and as ‘enrolled’ in the experiences of the retreat as a ‘therapeutic landscape’, and questions how and what particular aspects of yoga practice (in intimate relation with place) give rise to therapeutic experiences

The impact of severe asthma on patients’ autonomy: a qualitative study

Background People living with severe asthma may have ongoing debilitating symptoms despite high‐dose treatment. Clinical guidelines for severe asthma recommend concepts such as patient centeredness, shared decision making and self‐management, at the heart of which lies autonomy. Objective This study aimed to explore the role of autonomy in patients’ narratives about their experiences of living with and managing severe asthma. Methods In‐depth semi‐structured interviews were video‐ and/or audio‐recorded and transcribed. Data were categorized using a hybrid approach to analysis incorporating both inductive and deductive methods, informed by the self‐determination construct of autonomy. Analysis and comparison across and within categories were conducted to develop final themes. Results Twenty‐nine face‐to‐face interviews, lasting 1.5‐4 hours, were conducted across Australia. Patients’ autonomy was enacted or challenged in a range of situations, such as interacting with health‐care providers, maintaining employment, managing symptoms, and dealing with threats to self‐identity. Two main themes were discerned from the analysis: (a) the desire to live an “unconstrained” life; and (b) preservation of self‐identity. Conclusion Our findings suggest that autonomy is broader than conventional medical concepts such as decision making and information seeking. Future research should consider these findings when developing and implementing patient‐driven self‐management interventions for those living with severe asthma
