Kuznetsov independence for interval-valued expectations and sets of probability distributions: Properties and algorithms

Kuznetsov independence of variables X and Y means that, for any pair of bounded functions f(X) and g(Y), E[f(X)g(Y)]=E[f(X)] *times* E[g(Y)], where E[.] denotes interval-valued expectation and *times* denotes interval multiplication. We present properties of Kuznetsov independence for several variables, and connect it with other concepts of independence in the literature; in particular we show that strong extensions are always included in sets of probability distributions whose lower and upper expectations satisfy Kuznetsov independence. We introduce an algorithm that computes lower expectations subject to judgments of Kuznetsov independence by mixing column generation techniques with nonlinear programming. Finally, we define a concept of conditional Kuznetsov independence, and study its graphoid properties.

Computing lower and upper expectations under epistemic independence

This paper investigates the computation of lower/upper expectations that must cohere with a collection of probabilistic assessments and a collection of judgements of epistemic independence. New algorithms, based on multilinear programming, are presented, both for independence among events and among random variables. Separation properties of graphical models are also investigated.

Assisstantship improves medical student preparedness for starting work

Background: The GMC has recommended introducing student assistantships during which final year students, under supervision, undertake most of the responsibilities of a FY1 doctor. The Medical School at Queen’s University Belfast in 2011/12 introduced an assistantship programme. We have evaluated the impact of the assistantship on students’ perception of their preparedness for starting work.
Methods: Students were asked to complete a questionnaire at the beginning of the assistantship. It assessed the students’ perception of their preparedness in five areas: clinical and practical skills, communications skills, teaching and learning, understanding the work environment and team working. After the assistantship they again completed the questionnaire. Comparison of the results allowed an assessment of the impact of the assistantship.
Results: There was a statistically significant improvement in the students' perception of their preparation for 49 of 56 tasks contained within the questionnaire. After the assistantship 81.2% of students felt well prepared for starting work compared with 38.9% before the assistantship. 93.9% agreed that the assistantship had improved their preparedness for starting work.
Conclusions: The assistantship at Queen’s University improves medical students’ perception of their preparedness for starting work. The majority of medical students feel well prepared for starting work after completing the assistantship.

The community trigger for anti-social behaviour: protecting victims or raising unrealistic expectations?

In October 2014, a statutory remedy for victims of anti-social behaviour became available called the community trigger. It affords complainants a right to request a review of their case if they consider that the response from local agencies has been inadequate. The Government has hailed the reform as “putting victims first”. This article first explores the context behind this reform. This includes a number of high profile cases involving the deaths of complainants after systematic failures led to prolonged exposure to anti-social behaviour. The article then examines the provisions and how they are likely to operate in practice. It argues that whilst much will depend upon implementation, the community trigger has the potential to improve the level of service offered to vulnerable complainants without necessarily impacting adversely on the rights of alleged perpetrators. As such, the community trigger may provide a model from which other areas of the criminal justice system may draw.

Northern Ireland and ‘The Troubles’, outlining an innovative approach to nursing/midwifery student teaching and module evaluation

This discussion paper outlines an approach to developing and evaluating an educative programme primarily delivered by lay `citizen trainers’ in educating student nurses, and student midwives to the impact of and experience of extended and extensive civil unrest within their communities (`the Troubles’ ). This is drawn from experience within the Northern Ireland `Troubles’ and all of the citizen trainers were directly affected physically/psychologically. The programme was intended to both educate but primarily to help facilitate student nurses and student midwives to better understanding to experience and context and to more effective care delivery to those affected by/damaged by `the Troubles’. Evaluation of the teaching and learning by the students was significantly positive.
