Despite being largely supportive of their sibling with an autism spectrum disorder (ASD), some siblings without ASD also feel the effects of the disorder particularly in relation to challenging behaviour and lack of empathy. The purpose of this paper is to explore the experiences adults who have a sibling with ASD and intellectual disability (ID) with challenging behaviour.

Interviews were conducted with 11 capacitous adult siblings of service users who have ASD and ID as well as a history of challenging behaviour. A modified version of the autism Parenting Stress Index was used to assess the impact on those siblings. thematic analysis was utilised to analyse their responses.

Four main themes emerged from the interviews, which highlighted that challenging behaviour can cause emotional losses and can impact upbringing and the sibling relationship. Despite the siblings making adjustments, they continue to have concerns for the future.

Chronic challenging behaviour can impact on siblings, and it is important to support entire families, and not exclusively parents.

The purpose of this paper is to report on and evaluate focus groups and privacy diary/interview methods used in a qualitative study of on‐line privacy.

The paper is a discursive evaluation of two methods employed to study on‐line privacy, informed by and situated in interpretive and constructivist approaches to knowledge.

The paper argues for the value of qualitative research methods in study of on‐line privacy. It confronts the positivist paradigm that informs much of the work in the field by foregrounding the need for methodological plurality in the study of privacy as relational, situated, dynamic and contextual. It deals with the notion of “sensitivity” as well as introducing often neglected issue of logistical challenges in qualitative research.

The paper contributes to the existing debates about the value of employment of qualitative research methods broadly, as well as in the study of on‐line privacy more specifically. It demonstrates a range of advantages and challenges in use of the two methods, providing recommendations of how to supplement them. It opens up the discussion of process of sensitizing of the participants and thus the “co‐construction” of knowledge.

With interviews in South Africa and London, Chris Phillips reports on the dangerously‐nationalistic US moves which have taken the monetary world away from its gold base and at the same time preserved the dollar — and election‐minded Nixon.

Research on creative workers speaks to the relative lack of job opportunities available, the role that changing production logics play in shaping such opportunities, and gender disparities in success. Tracking 22,561 hits found on Billboard's mainstream charts, we examine various factors that may spur or hamper the success of female recording acts. We find that the expanding logic of decentralized production eliminates the negative effect of concentration on the success of female acts and that the presence of successful female acts in one period bodes well for subsequent female acts, until a glass ceiling of sorts is reached.

Because of the volatile business environment, organizations are in a state of unprecedented change, which numerous observers have called chaos. Under current, unstable, perhaps chaotic, conditions, there is a window of opportunity for human resources (HR)/change leader professionals to step up to areas of conflict, chaos, and confusion in organizations. The opportunity currently available to HR professionals is obviously open to all stakeholders in organizations. Eventually someone will claim this opportunity. In changing, unpredictable, chaotic organizations, the HR groups stand out as likely claimants because of their generally applicable skill sets. However, this is a new, confrontational leadership role that HR personnel have not filled in the past. Some HR personnel will not be interested, some will not have what it takes. HR stars will definitely be “in the gate” and have what it takes. This paper describes how HR stars behave, and what they can accomplish in chaotic organizations.

The purpose of the paper is to back-test value-at-risk (VaR) models for conditional distributions belonging to a Generalized Hyperbolic (GH) family of Lévy processes – Variance Gamma, Normal Inverse Gaussian, Hyperbolic distribution and GH – and compare their risk-management features with a traditional unconditional extreme value (EV) approach using data from future contracts return data of S&P500, FTSE100, DAX, HangSeng and Nikkei 225 indices.

The authors apply tail-based and Lévy-based calibration to estimate the parameters of the models as part of the initial data analysis. While the authors utilize the peaks-over-threshold approach for generalized Pareto distribution, the conditional maximum likelihood method is followed in case of Lévy models. As the Lévy models do not have closed form expressions for VaR, the authors follow a bootstrap method to determine the VaR and the confidence intervals. Finally, for back-testing, they use both static calibration (on the entire data) and dynamic calibration (on a four-year rolling window) to test the unconditional, independence and conditional coverage hypotheses implemented with 95 and 99 per cent VaRs.

Both EV and Lévy models provide the authors with a conservative proportion of violation for VaR forecasts. A model targeting tail or fitting the entire distribution has little effect on either VaR calculation or a VaR model’s back-testing performance.

To the best of the authors’ knowledge, this is the first study to explore the back-testing performance of Lévy-based VaR models. The authors conduct various calibration and bootstrap techniques to test the unconditional, independence and conditional coverage hypotheses for the VaRs.
