A Comparative Study of Introductory and Undergraduate Econometric Textbooks

There are currently numerous introductory and undergraduate econometric textbooks. This is unfortunate for both the new student of econometrics wishing to purchase a textbook, and for course conveners who have the responsibility of recommending a text. There is a shortfall in the literature reviewing such textbooks and thus providing assistance for the appropriate choice of textbook. This paper is an attempt to fill this gap, by comprehensively reviewing some of the mainstream undergraduate econometric textbooks

Non-discursive philosophy by imagining new practices through design

In this commentary on Rietveld’s inaugural lecture, we exemplify with one of our design cases for project Expedition RWS 2050, how Rietveld’s and our method are complementary. Within this project, RWS invited us to contribute our design skills and make relevant future scenarios experienceable. To scaffold imaginative discussions about everyday life in 2050 with a cross-section of the Dutch population, we wrote seven short speculative stories and designed a set of physical discussion tools. When looking at this design case and the cases Rietveld describes in his inaugural lecture, one can see that we both are guided by and contributing to the development of ecological and enactive philosophy, which rejects the dichotomy between sensorimotor and higher cognition. In his approach, Rietveld pushes the boundaries of the affordances of the material during the making process, whereas we predominantly investigate the affordances of the things and practices which we have designed. Despite these differences, we are both pursuing engagement with philosophical practice through non-discursive means while imagining new sociomaterial practices

Strong connectivity of sensor networks with double antennae

Inspired by the well-known Dipole and Yagi antennae we introduce and study a new theoretical model of directional antennae that we call double antennae. Given a set P of n sensors in the plane equipped with double antennae of angle φ and with dipole-like and Yagi-like antenna propagation patterns, we study the connectivity and stretch factor problems, namely finding the minimum range such that double antennae of that range can be oriented so as to guarantee strong connectivity or stretch factor of the resulting network. We introduce the new concepts of (2,φ)-connectivity and φ-angular range r φ (P) and use it to characterize the optimality of our algorithms. We prove that r φ (P) is a lower bound on the range required for strong connectivity and show how to compute r φ (P) in time polynomial in n. We give algorithms for orienting the antennae so as to attain stro

‘All of us together in a blurred space’: principles for co-creating curriculum with international partners

This paper shares an innovative methodology to \u27co-create\u27 a curriculum with eleven international community development organisations from seven countries to prepare undergraduate students for international work-integrated learning activities. The co-creation process was complex, messy, and always evolving. Here we reflect on and document the process, identifying three key methodological principles that might guide the co-creation process for others. These principles embrace the unpredictable, emotional, and personal reality of bringing together diverse ideas and perspectives, as well as opening up possibilities for more creative ways of communicating and listening to what is seen, heard, and felt
