Current issues in pictorial semiotics. Lecture two: The Psychology and Archaeology of Semiosis.

In this lecture, we will discuss the emergence of the semiotic function, both ontogenetically and phylogenetically, and we will consider the part played by the picture sign in this development. In order to demonstrate that pictures are indeed signs, we will explore the basic elements of the sign presupposed but never put into focus neither by Saussure nor by Peirce. Indeed, explorations in the psy

Scholarship of teaching and learning at the highest level? Experiences from a study program for doctoral supervisors

The Swedish HE Ordinance requires all supervisors of doctoral students to undergo introductory training. The content, goals, learning outcomes and duration is not specified by the Ordinance and thus practices vary between institutions. In 2009/2010, a new study program for doctoral supervisors was launched at Lund University. The program was designed to:- provide research-based support for doctora

The Duration of Trade Revisited. Continuous-Time vs. Discrete-Time Hazards

The recent literature on the duration of trade has predominantly analyzed the determinants of trade flow durations using Cox proportional hazards models. The purpose of this paper is to show why it is inappropriate to analyze the duration of trade with continuous-time models such as the Cox model, and to propose alternative discrete-time models which are more suitable for estimation. Briefly, the

Structural health monitoring of large concrete structures

There is an increasing demand on the safety and reliability of the civil structures that make up our cities and infrastructure. The field of structural health monitoring aims to provide continuous non-destructive evaluation of such structures. Large concrete structures, such as nuclear power plants, provide a challenge when implementing such systems, if minor damage is to be detected. For methods

Corporate Governance in Scandinavia: Comparing Networks and Formal Institutions

This article addresses the role of formal institutions and informal networks on corporate governance practices. The existing corporate governance literature has mostly examined the formal institutions, such as the effect of legal systems. Our contribution is to consider the effect of informal “small world” characteristics of ownership and board networks. We use the case of Scandinavia (Denmark, No

Retrofitted Solar Domestic Hot Water System for Single-Family Electrically-Heated Houses: Development and testing

In Sweden, there are roughly half a million single family houses that use electric heating for both domestic hot water production and space heating. Since electricity is the most expensive energy source in Sweden, it is interesting to install a high solar fraction solar thermal system to reduce the energy use in these houses. One of the most significant bottlenecks for deployment of solar heating
