Up to 74% of marketing budgets can be spent on sales promotions, with manufacturers, suppliers and retailers employing a wide range of incentives from price discounts to complex Omni-channel consumer competitions and contests. Sales promotions are a vital strategic and tactical tool within the marketing value chain and those responsible for campaign planning must negotiate objectives, options and outcomes to ensure their initiatives deliver real results in competitive trading environments. Managers with limited understanding of the principles and practices of sales promotions often rely on past experience or preferences to guide their decision-making. Not surprisingly, without guiding principles, many sales promotions fail to achieve their full potential. This book is a resource for sales promotion professionals looking to improve the effectiveness of their sales promotions. The book is based on an extensive review of over 400 articles and cases. It presents the findings of global research which explores the very DNA of sales promotions, including their role, rationale, nature and function, key decision-making processes and campaign evaluation. Illustrations of sales promotion decision-making in practice based on research conducted in the retail supply chain is also incorporated. This book offers a comprehensive and critical appreciation of the core concepts that underpin sales promotion thinking. The goal is to empower decision-makers, consultants and stakeholders to make confident, informed and effective campaign decisions in the complex field of sales promotions.

In group decision making (GDM) problems, ordinal data provide a convenient way of articulating preferences from decision makers (DMs). A number of GDM models have been proposed to aggregate such kind of preferences in the literature. However, most of the GDM models that handle ordinal preferences suffer from two drawbacks: (1) it is difficult for the GDM models to manage conflicting opinions, especially with a large number of DMs; and (2) the relationships between the preferences provided by the DMs are neglected, and all DMs are assumed to be of equal importance, therefore causing the aggregated collective preference not an ideal representative of the group's decision. In order to overcome these problems, a two-stage dynamic group decision making method for aggregating ordinal preferences is proposed in this paper. The method consists of two main processes: (i) a data cleansing process, which aims to reduce the influence of conflicting opinions pertaining to the collective decision prior to the aggregation process; as such an effective solution for undertaking large-scale GDM problems is formulated; and (ii) a support degree oriented consensus-reaching process, where the collective preference is aggregated by using the Power Average (PA) operator; as such, the relationships of the arguments being aggregated are taken into consideration (i.e., allowing the values being aggregated to support each other). A new support function for the PA operator to deal with ordinal information is defined based on the dominance-based rough set approach. The proposed GDM model is compared with the models presented by Herrera-Viedma et al. An application related to controlling the degradation of the hydrographic basin of a river in Brazil is evaluated. The results demonstrate the usefulness of the proposed method in handling GDM problems with ordinal information.

Drug use is endemic within offender populations and, as a result, considerable heterogeneity can be found in drug-related crime. Expertise in drug-related offending covers an equally broad base from internal mental processes through skill acquisition to social interactions. This review considers decision making and expertise for crimes in the domains of direct causal effects (e.g., burglary) and non-causal relationships (e.g., apprehension avoidance, detection). Also considered is the notion of expertise as it applies to addiction, in particular the conscious and unconscious goal-directed behaviors articulated in the Selfish Goal model (Huang & Bargh, 2014) and a cool cognition/hot affect dual processing model of criminal decision making (Van Gelder, 2013). The review findings would suggest (a) the need for more focused research into whether expertise differs as a function of drug use and (b) a paradigm shift in terms of treatment for drug-using offenders.

 Background: The value placed on types of evidence within decision-making contexts is highly dependent on individuals, the organizations in which the work and the systems and sectors they operate in. Decision-making processes too are highly contextual. Understanding the values placed on evidence and processes guiding decision-making is crucial to designing strategies to support evidence-informed decision-making (EIDM). This paper describes how evidence is used to inform local government (LG) public health decisions.
Methods: The study used mixed methods including a cross-sectional survey and interviews. The Evidence-Informed Decision-Making Tool (EvIDenT) survey was designed to assess three key domains likely to impact on EIDM: access, confidence, and organizational culture. Other elements included the usefulness and influence of sources of evidence (people/groups and resources), skills and barriers, and facilitators to EIDM. Forty-five LGs from Victoria, Australia agreed to participate in the survey and up to four people from each organization were invited to complete the survey (n = 175). To further explore definitions of evidence and generate experiential data on EIDM practice, key informant interviews were conducted with a range of LG employees working in areas relevant to public health.
Results: In total, 135 responses were received (75% response rate) and 13 interviews were conducted. Analysis revealed varying levels of access, confidence and organizational culture to support EIDM. Significant relationships were found between domains: confidence, culture and access to research evidence. Some forms of evidence (e.g. community views) appeared to be used more commonly and at the expense of others (e.g. research evidence). Overall, a mixture of evidence (but more internal than external evidence) was influential in public health decision-making in councils. By comparison, a mixture of evidence (but more external than internal evidence) was deemed to be useful in public health decision-making.
Conclusions: This study makes an important contribution to understanding how evidence is used within the public health LG context.

A recent study in Science indicated that the confidence of a decision maker played an essential role in group decision making problems. In order to make use of the information of each individual's confidence of the current decision problem, a new hybrid weighted aggregation method to solve a group decision making peoblem is proposed in this paper. Specifically, the hybrid weight of each expert is generated by a convex combination of his/her subjective experience-based weight and objective problem-domain-based weight. The experience-based weight is derived from the expert's historical experiences and the problem-domain-based weight is characterized by the confidence degree and consensus degree of each expert's opinions in the current decision making process. Based on the hybrid weighted aggregation method, all the experts' opinions which are expressed in the form of fuzzy preference relations are consequently aggregated to obtain a collective group opinion. Some valuable properities of the proposed method are discussed. A nurse manager hiring problem in a hospital is employed to illustrate that the proposed method provides a rational and valid solution for the group decision making problem when the experts are not willing to change their initial preferences, or the cost of change is high due to time limitation.

To date, there has been limited examination of variables that influence sentencing in child sexual abuse cases. This study examines the extent to which offence characteristics (such as the number of offences, number and age of victims), the behaviour and perceived credibility of the victim impact upon both sentence length and the setting of earliest parole dates. Analyses conducted using data from 66 adjudicated cases of child sexual assault from the County Court of Victoria, Australia revealed that longer sentences were handed down to offenders who had perpetrated multiple offences, or who had committed offences against younger children. Lower levels of victim credibility were associated with shorter sentences and earlier parole dates for offenders, which were also associated with the presence of more harmful behavioural indicators of abuse. The findings are discussed regarding the importance of presenting evidence about the behaviour of victims following sexual abuse in criminal trials. © 2013 Copyright National Organisation for the Treatment of Abusers.

Modern healthcare is getting reshaped by growing Electronic Medical Records (EMR). Recently, these records have been shown of great value towards building clinical prediction models. In EMR data, patients' diseases and hospital interventions are captured through a set of diagnoses and procedures codes. These codes are usually represented in a tree form (e.g. ICD-10 tree) and the codes within a tree branch may be highly correlated. These codes can be used as features to build a prediction model and an appropriate feature selection can inform a clinician about important risk factors for a disease. Traditional feature selection methods (e.g. Information Gain, T-test, etc.) consider each variable independently and usually end up having a long feature list. Recently, Lasso and related l1-penalty based feature selection methods have become popular due to their joint feature selection property. However, Lasso is known to have problems of selecting one feature of many correlated features randomly. This hinders the clinicians to arrive at a stable feature set, which is crucial for clinical decision making process. In this paper, we solve this problem by using a recently proposed Tree-Lasso model. Since, the stability behavior of Tree-Lasso is not well understood, we study the stability behavior of Tree-Lasso and compare it with other feature selection methods. Using a synthetic and two real-world datasets (Cancer and Acute Myocardial Infarction), we show that Tree-Lasso based feature selection is significantly more stable than Lasso and comparable to other methods e.g. Information Gain, ReliefF and T-test. We further show that, using different types of classifiers such as logistic regression, naive Bayes, support vector machines, decision trees and Random Forest, the classification performance of Tree-Lasso is comparable to Lasso and better than other methods. Our result has implications in identifying stable risk factors for many healthcare problems and therefore can potentially assist clinical decision making for accurate medical prognosis.

Investigated are the decision-making styles of Australian consumers for everyday products. Specifically, the applicability of Sproles and Kendall's Consumer Styles Inventory (CSI) is examined in relation to the purchase of everyday products. Based on a sample of 214 respondents who had recently purchased a confectionery product, exploratory and confirmatory factor analysis is used to validate the CSI. Six decision-making styles are retained from the original CSI ('perfectionist, high quality', 'confused by over-choice', 'impulsive', 'habitual/brand loyal', 'novelty/fashion', and 'recreation conscious') and one new decision-making style is developed ('rational, price conscious'). Marketing and managerial implications are discussed.

It is commonly assumed that, in the realm of ethical decision making at the end-of-life, ‘luck’ and ‘risk’ do not intrude. Nonetheless ‘moral luck’ (where happenstance makes a moral difference) does intrude and can have an unanticipated impact on the ultimate moral outcomes of end-of-life care. In the interests of upholding the ethical standards of end-of-life care, healthcare providers have increasingly relied on ethical principlism as a rational decision-guiding frame in the sincere belief that such an approach will enable patient selfdetermination and control over treatment decisions when needing end-of-life care. Due to contextual variables and associated uncertainties in end-of-life care, however, the intended moral outcomes of appeals to commonly accepted ethical principles (in particular the principle of autonomy) are not always realized. What is not always appreciated is that whether ‘good’ or ‘bad’ moral outcomes are achieved can be as much a matter of chance as of choice. This essay explores the relevance and possible implications of moral luck in end-of-life decision making and care. A key conclusion of the paper is that the notion of moral luck needs to be taken seriously in end-of-life care contexts since it can have an unanticipated impact on the outcomes of the decisions that are made and thereby on the moral interests of patients facing the end of their lives.

Purpose - This study aims to specifically focus on the lower-involvement young adult voters within the Australian compulsory voting context. It explores voters’ political decision-making by considering the influence of the consumer behaviour theory of involvement. Design/methodology/approach - A thematic analysis was conducted to analyse the interviews within the two research questions: information seeking and decision-making. Findings - Key themes within information seeking are the reach of the information available, the frequency of the information presented, the creativity of the message and one-way versus two-way communication. Key themes within evaluation are promise keeping/trust, achievements or performance and policies. Lower-involvement decision-making has the potential to be a habitual, limited evaluation decision. However, issues of trust, performance and policies may encourage evaluation, thereby reducing the chances of habitually voting for the same party as before. Practical implications - This new area of research has implications for the application of marketing for organisations and political marketing theory. Considering voting decision-making as a lower-involvement decision has implications for assisting the creation and adaptation of strategies to focus on this group of the population. Originality/value - The compulsory voting environment creates a unique situation to study lower-involvement decision-making, as these young adults are less likely to opt out of the voting process. Previous research in political marketing has not specifically explored the application of involvement to young adult voting within a compulsory voting environment.
