Voting behaviour on free votes: Simply a matter of preferences?

Previous research examining the outcomes of free votes concludes that voting behaviour is determined in large part by MPs’ personal preferences. However, most studies do not measure preferences directly and ignore other possible determinants of voting behaviour. This piece illustrates the need to address these shortcomings before one concludes that preferences explain the outcomes of free votes. I illustrate this by examining a series of divisions on the issue of House of Lords reform. Using direct measures of preferences and controlling for alternative explanations, the analysis suggests MPs’ preferences had little effect on voting behaviour on this issue.

Computational techniques for a simple theory of conditional preferences

A simple logic of conditional preferences is defined, with a language that allows the compact representation of certain kinds of conditional preference statements, a semantics and a proof theory. CP-nets and TCP-nets can be mapped into this logic, and the semantics and proof theory generalise those of CP-nets and TCP-nets. The system can also express preferences of a lexicographic kind. The paper derives various sufficient conditions for a set of conditional preferences to be consistent, along with algorithmic techniques for checking such conditions and hence confirming consistency. These techniques can also be used for totally ordering outcomes in a way that is consistent with the set of preferences, and they are further developed to give an approach to the problem of constrained optimisation for conditional preferences.

Hicks meets Hotelling: the direction of technical change in capital-resource economies

We analyze a two-sector growth model with directed technical change where man-made capital and exhaustible resources are essential for production. The relative profitability of factor-specific innovations endogenously determines whether technical progress will be capital- or resource-augmenting. We show that any balanced growth equilibrium features purely resource-augmenting technical change. This result is compatible with alternative specifications of preferences and innovation technologies, as it hinges on the interplay between productive efficiency in the final sector, and the Hotelling rule characterizing the efficient depletion path for the exhaustible resource. Our result provides sound micro-foundations for the broad class of models of exogenous/endogenous growth where resource-augmenting progress is required to sustain consumption in the long run, contradicting the view that these models are conceptually biased in favor of sustainability.

What’s in a (Party) Name?: Examining preferences, discipline, and social identity in a parliamentary free vote

In trying to understand the effects of political parties on shaping the voting behaviour of legislators, research has attempted the difficult task of separating the effects of preferences from rules used by party leaders to enforce discipline. However, little research has explored the prospect that party labels also reflect a social identity that is independent of legislators’ preferences and the rules used by party leaders to enforce discipline. In this study we examine that possibility, employing a data set that permits us to control both for leadership-based effects and legislator preferences on a 2000 free vote dealing with stem cell research. Using the British Representation Studies 1997 – which interviewed Members of Parliament regarding their preferences on several key issues related to the bill – we find significant evidence that party-as-identification plays a role in shaping how legislators vote, even after preferences and discipline are accounted for.

The views of general practitioners on advance care planning for patients living with dementia

Background Advance care planning (ACP) facilitates communication
and understanding of preferences, nevertheless the use of
ACPs in primary care for patients with dementia is low. The disease’s
uncertain course and the inability to communicate with
the patient living with dementia are significant challenges for
GPs.
Aim The purpose of this study was to describe the attitudes and
practice preferences of GPs working within the UK’s National
Health System (NHS) regarding communication, and decisionmaking
for patients with dementia and their families
Methods A cross-sectional survey, using a purposive, cluster sample
of GPs across Northern Ireland with registered dementia
patients was used.
Results One hundred and thirty-three GPs (40.6%) participated
in the survey, representing 60.9% of surveyed practices. While
most respondents regarded dementia as a terminal disease
(96.2%) only 37.6% felt that palliative care applied equally from
the time of diagnosis to severe dementia. While most respondents
thought that early discussions would facilitate decision-making
during advanced dementia (61%), respondents were divided
on whether ACP should be initiated at the time of diagnoses
(39.8% in favour vs 45.8% disagreed). Interestingly, GPs who
were longer in practice placed greater importance on the presence
of an advance directive (F (2, 124) = 3.38, p = 0.037).
Discussion The timing of initiating ACP varies across individuals
requiring GPs to carefully consider strategies and receptiveness
of the patient and family carer.
Conclusion The findings promote both ongoing training in communication
and dementia management for GPs to meet the
needs of their patients living with dementia.

General practitioners perceptions on advance care planning for patients living with dementia

BACKGROUND: Advance care planning (ACP) facilitates communication and understanding of preferences, nevertheless the use of ACPs in primary care is low. The uncertain course of dementia and the inability to communicate with the patient living with dementia are significant challenges for GPs to initiate discussions on goals of care.

METHODS: A cross-sectional survey, using a purposive, cluster sample of GPs across Northern Ireland with registered dementia patients was used. GPs at selected practices received the survey instrument and up to four mail contacts was implemented.

RESULTS: One hundred and thirty-three GPs (40.6%) participated in the survey, representing 60.9% of surveyed practices. While most respondents regarded dementia as a terminal disease (96.2%) only 37.6% felt that palliative care applied equally from the time of diagnosis to severe dementia. While most respondents thought that early discussions would facilitate decision-making during advanced dementia (61%), respondents were divided on whether ACP should be initiated at the time of diagnoses. While most respondents felt that GPs should take the initiative to introduce and encourage ACP, most survey participants acknowledged the need for improved knowledge to involve families in caring for patients with dementia at the end of life and that a standard format for ACP documentation was needed.

CONCLUSION: Optimal timing of ACP discussions should be determined by the readiness of the patient and family carer to face to face end of life. ACP discussions can be enhanced by educational strategies directed towards the patient and family carer that enable shared decision-making with their GP when considering options in future care.
