Intellectual competence and academic performance: A Spanish study

This study assessed the explanatory power of the intellectual competence (IC) model for understanding the relationship among the main ability and non-ability determinants of academic performance (AP) in a sample of Spanish undergraduates. Thus it attempted to replicate the preliminary evidence for this model provided in a recent UK study and expand on it by including more comprehensive measures of intelligence and AP. Results showed mixed support for individual paths, but good support for the overall model. The expanded IC model showed that some individual difference factors explain AP variance that is common to high school, university entry, and university exam grades, whereas other individual differences explained AP variance specific to university. Inconsistencies, limitations, and implications are discussed.     

Assessment of the state of conservation of stone artworks after laser cleaning: comparison with conventional cleaning results on a two-decade follow up

The utilization of laser light to produce fine and selective cleaning of superficial deposits and encrustation from stones was originally proposed more than 20 years ago by John Asmus who performed pioneering trials of laser cleaning on stone façades in Venice, Cremona and Padua. The opportunity to collect stone samples from these sites allowed us to carry out an original study aimed at evaluating the conservation state of stone surfaces cleaned 10–20 years ago by means of three different techniques: Nd:YAG laser radiation, micron sandblasting and chemical pads. Samples of various stone types, as Istria limestone, Botticino limestone and Nanto sandstone were collected and examined by means of optical and SEM microscopy, FT/IR, and EDAX analyses. The results provided preliminary indications that the state of conservation of stone surfaces previously subjected to laser cleaning is generally better in comparison with those which concurrently underwent mechanical and chemical cleaning.     

Thinking about engineering practice: a change in technological activity

The following paper puts forward a distinction in the way of understanding the idea of the ‘technological phenomenon’ from a vision of the concept considered as a traditional artefact and seen as a tool, machines, processes and efficient transformations, to a global view that can serve the technical, organizational and cultural aspects of technology. On the other hand, it puts forward a series of proposals pointing to the incorporation of this new conceptual approach to the engineer formation so that he/she can be aware with a critical and responsible sense of the implications that the technological work bears passing from a technological activity to a technological practice as such.     

Investment in Paintings: A Short-Run Price Index

This paper analyses the performance of a speculative investment in paintings during the period 1987–1995 by applying a modified repeat sales technique to a sample of 1446 repeat sales. Since this period is characterised by a boom and a non-boom sub-period, a price risk term is introduced to estimate influences that only affect a painting's value upon its sale, by isolating shocks that can cause realised returns to stray from expectations. The main finding is that from 1987 to 1991 an investment in paintigs performs well if compared with alternative forms of investment, such as U.S. stocks, U.S. 30 year government bonds and gold; by contrast, from 1992 to 1995 returns are lower, with the exception of 1993.     

Factors affecting university-industry R&D projects: The importance of searching, screening and signalling

This paper presents an empirical analysis of the determinants of research cooperation between firms and Public research organisations (PROs) for a sample of innovating small and medium-sized enterprises (SMEs). The econometric analysis is based on the results of the KNOW survey carried out in seven EU countries during 2000. In contrast to earlier works that provide information about the importance of PROs’ research, we know the number of firm/PRO collaborative research and development (R&D) projects. This allows us to study the determinants of firm collaboration with PROs in terms of both the propensity of a firm to undertake R&D projects with a university (do they cooperate or not) and the extent of this collaboration (number of R&D projects). Two questions are addressed. Which firms cooperated with PROs? And what are the firm characteristics that might explain the number of R&D projects with PROs? The results of our analysis point to two major phenomena. First, the propensity to forge an agreement with an academic partner depends on the ‘absolute size’ of the industrial partner. Second the openness of firms to the external environment, as measured by their willingness to search, screen and signal, significantly affects the development of R&D projects with PROs. Our findings suggest that acquiring knowledge through the screening of publications and involvement in public policies positively affects the probability of signing an agreement with a PRO, but not the number of R&D projects developed. In fact, firms that outsource research and development, and patent to protect innovation and to signal competencies show higher levels of collaboration.     

A literature review on knowledge management in SMEs

This paper provides a systematic review of the literature on knowledge management (KM) in small and medium enterprises (SMEs) and SME networks. The main objective is to highlight the state-of-the-art of KM from the management point of view in order to identify relevant research gaps. The review highlights that in recent years the trend of papers on the topic is growing and involves a variety of approaches, methodologies and models from different research areas. The vast majority of papers analysed focus on the topic of KM in the SME while there are only few papers analysing KM in networks populated by SMEs. The content analysis of the papers highlights six areas of investigation from which were derived ten research questions concerning three perspectives: the factors affecting KM; the impact of KM on firm’s performance; the knowledge management systems.
