title: Adversarial risk analysis for first-price sealed-bid auctions.

authors: Ejaz, Muhammad

subjects: adversarial risk analysis

abstract: Adversarial risk analysis (ARA) is an upcoming methodology that is considered to haveadvantages over the traditional decision-theoretic and game-theoretic approaches. ARAsolutions for ﬁrst-price sealed-bid (FPSB) auctions have been found but only under strongassumptions which make the model somewhat unrealistic. In this paper, we use ARAmethodology to model FPSB auctions using more realistic assumptions. We deﬁne a newutility function that considers bidders’ wealth, we assume a reserve price and ﬁnd solutionsnot only for risk-neutral but also for risk-averse as well as risk-seeking bidders. We modelthe problem using ARA for non-strategic play and level-k thinking solution concepts.

title: Supervisory skills training for the neglected supervisors: development and preliminary evaluation of an autonomy-supportive programme

authors: Yong, Amy

subjects: Andragogy

abstract: Purpose
Previous studies have demonstrated that an autonomy-supportive supervision style is associated with improved well-being and positive behaviours for supervisees. However, autonomy-supportive training (AST) has yet to be tailored to suit supervisors in low-skilled occupations for whom traditional pedagogical approaches may be inappropriate. The purpose of this paper is to describe the development and preliminary evaluation of AST for these supervisors, using self-determination theory (SDT) and andragogical principles of adult learning.

Design/methodology/approach
SDT and andragogical principles were systematically integrated to develop (a 3 h) AST programme. The training sessions were trialled with 11 first-line supervisors in New Zealand as a preliminary evaluation of AST. The evaluation used open-ended questions following Kirkpatrick’s evaluation model and incorporated the trainer’s reflections.

Findings
Supervisors found AST relevant, easy to understand and suited to their approach to learning. Trainer’s reflections also provided insight into the challenges in conducting such training for supervisors in low-skilled occupations and the article makes suggestions to address these challenges.

Research limitations/implications
AST can be successfully tailored to first-line supervisors, indicating that an autonomy-supportive style of leadership is relevant for those employed in low-skilled occupations. This initial evaluation provides a foundation for future studies to conduct higher-level assessment of AST.

Practical implications
AST can be utilised to provide first-line supervisors with access to improved leadership development opportunities. Challenges of conducting this kind of training programme in a context of low-skilled occupations are addressed and recommendations made for organisations and trainers.

Originality/value
This study is novel as it demonstrates the development of AST, a leadership skills training, tailored to suit the needs of an understudied group, supervisors in low-skilled occupations.

title: Portfolio of Compositions: Systematic composition of cross-genre hybrid music

authors: Mayall, Jeremy Mark

subjects: cross-genre hybrid music

abstract: The research focus of this PhD thesis is the development of a new technique for composing original musical compositions in which elements from different musical genres are hybridised. The innovative aspect of achieving balanced hybridity is the development of a systematic approach to selecting and synthesising or hybridising key musical elements across a range of different genres. The major component of this submission is a portfolio of nine original works with attached CD/DVD recordings. 

1. Tracking Forward for viola, backing track and video 
2. The Long White Cloud for chamber band and electronics 
3. ‘Colorless green ideas sleep furiously’ for orchestra 
4. Push for Miles for electric bass and backing track 
5. Norse Suite for viola and cello 
6. The Foggy Field a studio construction 
7. Into the Nocturnal Sunshine for flute, viola, cello, drums and electronics 
8. One Night, New Breath for taonga puoro, viola, drums and electronics 
9. Sketches of an Intergalactic Earworm for piano trio and boombox

The accompanying documentation clarifies, and contextualises the creation and presentation of these works; and illuminates the aesthetic underpinnings and compositional techniques developed and utilised as a part of this hybrid-genre compositional approach. The structure of the supporting exegesis is in two parts: the methodology of practice-based research, and reflective investigation. Part One (Chapters 1 and 2) is an introductory overview; an observation of the existing literature and related work, relevant creative practice in the composer’s previous work; and the compositional methodology – including an explanation of the genre matrix. Part Two (Chapters 3 to 12) analyses the use of genre, the balance of hybridity, and relevant compositional techniques utilised in the development of each individual piece.
