Reluctant Generalised Additive Modelling

Sparse generalised additive models (GAMs) are an extension of sparse generalised linear models that allow a model's prediction to vary non-linearly with an input variable. This enables the data analyst build more accurate models, especially when the linearity assumption is known to be a poor approximation of reality. Motivated by reluctant interaction modelling, we propose a multi-stage algorithm, called reluctant generalised additive modelling (RGAM), that can fit sparse GAMs at scale. It is guided by the principle that, if all else is equal, one should prefer a linear feature over a non-linear feature. Unlike existing methods for sparse GAMs, RGAM can be extended easily to binary, count and survival data. We demonstrate the method's effectiveness on real and simulated examples.     

Enabling the language of accessible tourism

The growing body of literature on “accessible tourism” lacks a critical scholarly debate around its specific language use and nomenclatures. To fill this gap, this paper provides a first examination of language. Language provides a unique capability to resist, strengthen and reframe identities of individuals and groups, yet can also reinforce, weaken and perpetuate dominant worldviews of disability. A content analysis examined previous accessible tourism literature with results illustrating that diversity exists amongst the varying terminologies adopted by scholars. Terms were employed loosely, inconsistently and interchangeably, euphemistically with erroneous understandings and nuances. The paper concludes with critical discussion about the power of researchers to (re) produce oppression through language that maligns and misrepresents, or to (re) conceptualise and (re) construct the world we live in with liberating language that facilitates positive social change.     

A method for reducing information asymmetry in destination–airline relationships

We propose a measure of business risk in air travel demand at the route level that can reduce information asymmetry during route development negotiations between tourism destinations and airlines. Aviation-exposed risk (AER) conveys information about the level of uncertainty with regard to air travel demand from an airline’s perspective. Using AER, tourism destinations and air service development teams can evaluate their risks from the perspective of the airline and its network. From there, an assessment can be made as to the value of air services in certain circumstances, including whether a direct underwrite or risk share between airlines and destinations is viable and necessary. By applying a portfolio analysis to an airline’s network, we find evidence that AER does indeed mimic the actual capacity distribution of the network. This provides support for AER as a useful risk measure to be used in practice.     

Developing a multidimensional scale of customer-oriented deviance (COD)

Although frontline employees' bending of organizational rules and norms for customers is an important phenomenon, marketing scholars to date only broadly describe over-servicing behaviors and provide little distinction among deviant behavioral concepts. Drawing on research on pro-social and pro-customer behaviors and on studies of positive deviance, this paper develops and validates a multi-faceted, multi-dimensional construct term customer-oriented deviance. Results from two samples totaling 616 frontline employees (FLEs) in the retail and hospitality industries demonstrate that customer-oriented deviance is a four-dimensional construct with sound psychometric properties. Evidence from a test of a theoretical model of key antecedents establishes nomological validity with empathy/perspective-taking, risk-taking propensity, role conflict, and job autonomy as key predictors. Results show that the dimensions of customer-oriented deviance are distinct and have significant implications for theory and practice.     

Any complaints? A review of the framework of self-regulation in the Australian advertising industry

Prior to 1996, the Australian system of advertising self-regulation was regarded as a world model and many Asia-Pacific systems included components adapted from the Australian system. The recent changes to this system, encouraged by the abolition of the media accreditation system, consumer association pressure, criticism from the national advertisers association and the lack of a strong advertising agency presence, present an interesting framework in which to review the foundation concepts of self-regulation in advertising. This paper compares the new code of ethics with its predecessor and an international standard. It examines the performance of the code in terms of the number of complaints upheld and complaint by medium and product type and the voluntary response of advertisers. The findings suggest a weakening in the standard of advertising self-regulation in Australia, with fewer provisions in the Code of Ethics, a significantly fewer number of complaints upheld and no real power of enforcement. Although the case is Australian, it raises universal questions such as the vested interest of advertisers in controlling the process and roles of the consumer association, the media and the advertising agencies in guaranteeing the privilege of self-regulation.     

Medical Error Disclosure Training: Evidence for Values-Based Ethical Environments

Disclosure of medical and errors to patients has been increasingly mandated in the U.S. and Canada. Thus, some health systems are developing formal disclosure policies. The present study examines how disclosure training may impact staff and the organization. We argue that organizations that support “disclose and apologize” activities, as opposed to “deny and defend,” are demonstrating values-based ethics. Specifically, we hypothesized that when health care clinicians are trained and supported in error disclosure, this may signal a values-based ethical environment, and staff may be more committed to the organization. We surveyed 325 clinical care providers employed by a large hospital that had recently begun implementing disclosure policies and training. Disclosure training explained significant variance in perceptions of the ethical environment, and the ethical environment mediated the relationship between disclosure training and organizational commitment. Although this study explored disclosure of medical errors, organizational support for error disclosure is a concept that could be relevant for many types of organizations.     

The Moderating Effect of Individuals' Perceptions of Ethical Work Climate on Ethical Judgments and Behavioral Intentions

Dimensions of the ethical work climate, as conceptualized by Victor and Cullen (1988), are potentially important influences on individual ethical decision-making in the organizational context. The present study examined the direct and indirect effects of individuals' perceptions of work climate on their ethical judgments and behavioral intentions regarding an ethical dilemma. A national sample of marketers was surveyed in a scenario-based research study. The results indicated that, although perceived climate dimensions did not have a direct effect on behavioral intentions, there were significant moderating effects. Climates perceived as emphasizing social responsibility and rules/codes moderated the individual ethical judgment-behavioral intentions relationship such that individuals were less likely to say that they would engage in a questionable selling practice even when they themselves did not believe the practice to be unethical. Respondents were somewhat more likely to form intentions consistent with their judgment that the questionable practice was morally acceptable when the ethical climate was characterized by an emphasis on team/friendship.     

Analysts' Earnings Forecasts and the Value Relevance of 20-F Reconciliations from non-U.S. to U.S. GAAP

This study extends existing research into the value relevance of reconciliations to U.S. GAAP by examining the role of analysts' earnings forecasts in explaining potential market reactions to the earnings reconciliation. One possible reason why the evidence on the value relevance of the earnings reconciliation is weak is that earnings are forecast by analysts. Their forecasts may pre-empt some of the information content of the earnings reconciliation disclosures. Our findings indicate that analysts' forecasts are value relevant and that they play a pre-emptive role for some firms. For others, however, the earnings reconciliation has information content that is not pre-empted by analysts' forecasts.
