title: Do loyalty programs really enhance behavioral loyalty? An empirical analysis accounting for self-selecting members

authors: Leenheer, Jorna

subjects: loyalty programs

abstract: One of the pressing issues in marketing is whether loyalty programs really enhance behavioral loyalty. Loyalty program members may have a much higher share-of-wallet at the firm with the loyalty program than non-members have, but this does not necessarily imply that loyalty programs are effective. Loyal customers may select themselves to become members in order to benefit from the program. Since this implies that program membership is endogenous, we estimate models for both the membership decision (using instrumental variables) and for the effect of membership on share-of-wallet, our measure of behavioral loyalty. We use panel data from a representative sample of Dutch households who report their loyalty program memberships for all seven loyalty programs in grocery retailing as well as their expenditures at each of the 20 major supermarket chains. We find a small positive yet significant effect of loyalty program membership on share-of-wallet. This effect is seven times smaller than is suggested by a naïve model that ignores the endogeneity of program membership. The predictive validity of the proposed model is much better than for the naïve model. Our results show that creating loyalty program membership is a crucial step to enhance share-of-wallet, and we provide guidelines on how to achieve this.

title: Graph-RAT programming environment

authors: McEnnis, Daniel

subjects: computer science

abstract: Graph-RAT is a new programming environment specializing in relational data mining. It incorporates a number of different techniques into a single framework for data collection, data cleaning, propositionalization, and analysis. The language is functional where algorithms are executed over arbitrary sub-graphs of the data. Analytical results can be conducted using collaborative filtering or machine learning techniques. The example algorithms are under BSD license.

title: Tarāwhai Tāngata Rau

authors: Hiini, Anaha Te Wheoro

subjects: Tarāwhai

abstract: Ngāti Tarāwhai are a unique tribal group from the Te Arawa confederation of tribes.  Located around their traditional stronghold of Lake Okataina, Tarāwhai have endured throughout history to become a proud and noble clan, maintaining their culture and distinctive tribal practises.  Part of their survival throughout time has been their ability to rely on particular traits and attributes that have been portrayed and maintained by members of Tarāwhai across the generations.  These special characteristics have not only supported the development of Tarāwhai, but have also helped the evolution of Tarāwhai’s identity.

This thesis is concerned with four aspects that have been identified as common traits throughout Ngāti Tarāwhai history.  In particular, this study will look at the roles of leaders, tohunga, warriors and carving experts and explore how these qualities have featured significantly within Tarāwhai’s history for many generations.  Furthermore, this thesis will discuss how these aspects have influenced the development of the tribe from early time through to the present day.

It is the proposition of this thesis that the above mentioned attributes have shaped the people of Tarāwhai into the tribal group that they are today.  In addition, while Māori society has changed dramatically in the last 100 years, Tarāwhai continue to display these characteristics in a modern world, and they are still central to the reaffirmation of Tarāwhai identity and the overall wellbeing of the people.  Finally this thesis believes that these attributes must be maintained and perpetuated for Tarāwhi to have a secure place in the future.
