How much risk ought we to take? Exploring the possibilities of risk-sensitive consequentialism in the context of climate engineering

When it comes to assessing the deontic status of acts and policies in the context of risk and uncertainty, moral theories are often at a loss. In this paper we hope to show that employing a multi-dimensional consequentialist framework provides ethical guidance for decision-making in complex situations. The paper starts by briefly rehearsing consequentialist responses to the issue of risk, as well as their shortcomings. We then go on to present our own proposal based on three dimensions: wellbeing, fairness and probability. In the last section we apply our approach to a comparison of different climate policy options, including stratospheric solar-radiation management.

Human Perception of Laughter from Context-free Whole Body Motion Dynamic Stimuli

Laughter is a ubiquitous social signal in human interactions yet it remains understudied from a scientific point of view. The need to understand laughter and its role in human interactions has become more pressing as the ability to create conversational agents capable of interacting with humans has come closer to a reality. This paper reports on three aspects of the human perception of laughter when context has been removed and only the body information from the laughter episode remains. We report on ability to categorise the laugh type and the sex of the laugher; the relationship between personality factors with laughter categorisation and perception; and finally the importance of intensity in the perception and categorisation of laughter.

Digital Dermatitis in Dairy Cows: A Review of Risk Factors and Potential Sources of Between-Animal Variation in Susceptibility

Digital dermatitis (DD) is a bacterial disease that primarily affects the skin on the heels of cattle. It is a major cause of lameness in dairy cows and a significant problem for the dairy industry in many countries, causing reduced animal welfare and economic loss. A wide range of infection levels has been found on infected farms, prompting investigations into both farm level and animal level risk factors for DD occurrence. There also appears to be individual variation between animals in susceptibility to the disease. The identification of factors affecting individual variation in susceptibility to DD might allow changes in breeding policies or herd management which could be used to reduce DD prevalence. Factors mentioned in the literature as possibly influencing individual variation in susceptibility to DD include physical factors such as hoof conformation and properties of the skin, physiological factors such as the efficacy of the immune response, and behavioural factors such as standing half in cubicles. Further work is required to determine the influence of these factors, identify the genetic basis of variation, clarify the level of heritability of DD susceptibility and to determine how this is correlated with production and health traits currently used in breeding programmes.

Understanding Risk: Contributions from the Journal of Risk and Governance

During recent years, news headlines have been rife with criticisms of the risk management practices of public and private sector entities. These criticisms have often been accompanied by calls for greater transparency in the way government entities manage risks and communicate dangers to the public. Similarly, in the private sector, the internationalisation of economic activity has heightened concerns over the potential adverse implications of mismanagement and financial scandals, and has led to calls for greater regulation and supervision. While the responses of public sector agencies and private sector actors to these challenges have differed, they share a common acknowledgement that effective governance relies on the pro-active identification, assessment, and management of risks as well as appropriate regulatory frameworks.

This edited book covers a number of divergent topics illustrating the emergence of several novel themes in the area of economic and social risks. As a communality, these novel themes relate to the complexity in which human activity in this late stage of capitalist development is embedded. This risk-generating complexity, in turn, can be observed at several levels, including workplace hazards, governance problems within the private sector or the intersection between public and private, and in relation to the economic risks faced by larger entities such as national governments.

Understanding Risk: Recent Contributions from the Journal of Risk and Governance

Following on from the format of the previous Book Understanding Risk: Contributions from the Journal of Risk and Governance, this collection of recent contributions (including work by the editor) this book is divided in three sections .  The first section examines issues relating to corporate governance in the private sector, with emphasis being placed on issues of 'Board Decision Making,' Earnings Management and Audit Committee Effectiveness'  and ' Corporate Governance Failures.'  These contributions are complemented by the second sections which looks at governance and risk issues affecting the public sector, with a focus being places on 'Public Private Partnerships' and regulation of activities in the Life Sciences.'  Section three focuses on societal risk management in relation to health, safety and the environment.  In this context, contributions are presented in relation to major debates surrounding 'Rising Trends in Cancer Cases,' dilemmas surrounding 'Medical Self Help,' 'Mental Health Policy' and the use of 'Information Technology in Health Care.'

UK Public Private Partnerships and the Credit Crunch: A Case of Risk Contagion?

During the past twenty years, the UK has relied heavily on Public Private Partnerships (PPP) and especially the Private Finance Initiative in the procurement of infrastructure and services. Discussing the causes of the credit crunch and its effects on PPP, this paper notes that the provision of new public sector infrastructure and related services has been adversely affected by the impact of the credit crunch on Private Finance Initiatives (PFIs). These problems have arisen primarily from the unwillingness of commercial banks to replace collapsed PFI bond financing unless new PFI contracts reduce financial risks; which, in turn, is likely to increase the cost of these projects to the public sector. Additional financial strains have arisen for the UK government from the need to bail out collapsed PFI projects. Overall we find evidence that the UK commitment to PFI has not only increased immediate fiscal pressures on the UK when these have become least palatable, but has also created fiscal vulnerabilities at local and national levels which are likely to hamper the country’s ability to launch counter-cyclical responses to the ongoing crisis.

Further evidence consistent with Yqh as an indicator of risk of gonadal blastoma in Y-bearing mosaic Turner syndrome

An 8-year-old girl with some features of Turner syndrome and karyotype 45X/46XY had developed a bilateral gonadoblastoma in her rudimentary ovaries. Her normal Y chromosome showed the characteristic distal fluorescence, as seen in her father's. Another mosaic, this time 45X/46XidicY, and also with some Turner features had rudimentary ovaries, but no gonadoblastoma had developed at age 14. The nature of her idicY, which showed no fluorescent distal Yq and had one of the centromeres inactivated, was confirmed by in situ hybridisation with a Yp-specific probe. Using primers from a human Yp-specific sequence, we amplified DNA extracted from paraffin-embedded ovarian tissue from both cases, and from a normal testicle and a normal ovary as controls. The finding of the expected Y-derived PCR product in the rudimentary gonads from these mosaic patients indicates the presence of their Y chromosome in both. We discuss the validity of the findings, and the possible role of sequences in or near the fluorescent part of Yq in the origin of gonadoblastoma in Y-bearing mosaic Turner syndrome.

Comparing Social Work Students' Perceptions of Risk Using Online Discussion Fora: Lessons Learned from a European Pilot Project

Comparisons of international child welfare systems have identified two basic orientations to practice; a ‘child protection’ orientation and a ‘child welfare’ orientation, which are founded upon fundamentally different values and assumptions regarding the family, the origins of child care problems, and the proper role of the state in relation to the family. This paper describes a project which sought to compare how undergraduate social work students from three European Universities perceive risk in referrals about the welfare of children and to explore the impact of different cultural, ideological and educational contexts on the way in which risk is constructed by students. Students from Northern Ireland, Germany and Poland examined three vignettes via ten online discussion fora each of which provided a narrative summary of their discussion. The paper presents some findings from the analysis of the qualitative data emerging from the student discussions and draws out the lessons learned in terms of how the project was designed and implemented using online discussion fora.

Health care professionals’ experience, understanding and perception of need of advanced cancer patients with cachexia and their families: The benefits of a dedicated clinic.

Background: Cachexia has been defined as an on-going loss of skeletal muscle mass that cannot be fully reversed by conventional nutritional support. It can be found in up to 80% of patients with advanced cancer and has profound psycho-social consequences for patients and their families. There is a paucity of studies examining the role and experience of healthcare professionals in relation to cachexia and existing studies suggest that professional staff have limited understanding and do not intervene effectively.
Aim: To identify barriers and facilitators to good practice in cachexia care in order to inform future developments in service provision.
Design: An exploratory qualitative study was conducted employing semi-structured interviews with a range of healthcare professionals recruited purposefully from an Australian hospital. Interviews were conducted in private rooms within the hospital.
Setting/participants: A range of healthcare professionals responsible for cancer care were recruited from a large Australian teaching hospital.
Results: Interviews were conducted with 8 healthcare professionals responsible for delivering cancer care. Four themes were identified: formal and informal education, knowledge and understanding, truth telling in cachexia and palliative care, and, a multi-disciplinary approach. Findings show how improved knowledge and understanding across a staff body can lead to improved staff confidence and a willingness to address cancer cachexia and its consequences with patients and their families.
Conclusion: Comparison with previous studies illustrates the importance of improving knowledge and understanding about cachexia and how this can contribute to staff having the skills and experience necessary to address cachexia and provide an improved care experience for patients and carers.

Perception of Filtered Speech by Children with Developmental Dyslexia and Children with Specific Language Impairments

Here we use two filtered speech tasks to investigate children’s processing of slow (<4 Hz) versus faster (∼33 Hz) temporal modulations in speech. We compare groups of children with either developmental dyslexia (Experiment 1) or speech and language impairments (SLIs, Experiment 2) to groups of typically-developing (TD) children age-matched to each disorder group. Ten nursery rhymes were filtered so that their modulation frequencies were either low-pass filtered (<4 Hz) or band-pass filtered (22 – 40 Hz). Recognition of the filtered nursery rhymes was tested in a picture recognition multiple choice paradigm. Children with dyslexia aged 10 years showed equivalent recognition overall to TD controls for both the low-pass and band-pass filtered stimuli, but showed significantly impaired acoustic learning during the experiment from low-pass filtered targets. Children with oral SLIs aged 9 years showed significantly poorer recognition of band pass filtered targets compared to their TD controls, and showed comparable acoustic learning effects to TD children during the experiment. The SLI samples were also divided into children with and without phonological difficulties. The children with both SLI and phonological difficulties were impaired in recognizing both kinds of filtered speech. These data are suggestive of impaired temporal sampling of the speech signal at different modulation rates by children with different kinds of developmental language disorder. Both SLI and dyslexic samples showed impaired discrimination of amplitude rise times. Implications of these findings for a temporal sampling framework for understanding developmental language disorders are discussed.
