What are the main explanations of occupational diseases and accidents at work in the agricultural sector? A panel analysis for Italian regional data

The aim of this paper is to investigate the causes of occupational diseases and accidents at work (ODA) in the Italian agricultural sector. To this end, we proceed with a two-stage analysis of Italian regional data for the period 1976–2004. The first phase of the analysis shows that in the Italian agricultural sector productivity Granger-causes ODA, and not vice versa. The results of the econometric estimates in the second stage of the analysis show that an increase in “productivity pressure” (associated with an increase in production rhythms) will produce, in the long run, an increase in accidents on less serious ODA (or temporary ODA); the same effect will not be observed on the more serious ODA (or permanent ODA). We verify how pro work legislation reduces ODA and how this effect is strengthened in the long-run. In addition, we observe that in the long-run the increase in the “pressure on workers” (associated with a high unemployment rate and a high probability of being fired) is the main cause of the increase in less and more serious ODA.     

Information flows within and across sectors in Chinese stock markets

We examine the patterns of information flows within and across sectors of the two Chinese stock exchanges in Shanghai and Shenzhen during 1994–2001. Using the generalized forecast error variance decomposition, we find a high degree of interdependence, indicating that the sectors are highly integrated and sector prices reflect information from other sectors. Industry is the most influential sector in both exchanges, while Finance in Shenzhen is the least integrated with other sectors. Implications of the findings for investors and policymakers are also discussed.     

The influence of variables of attitude on collective entrepreneurship

In the current global corporate climate that surrounds us, firms would do well to encourage the talent and creativity of their employees in order to achieve success. This is achieved, not by giving priority to individual talent, but by optimizing the collective as a whole and the firm’s activity based on team work and joint effort. Heads of organizations might benefit from creating a favorable context for the birth and growth of collective internal cooperation, which is understood to be the collective ability to create and innovate on the part of the team, the firm or the organization. Having contrasted our hypotheses through research on Spanish firms, we have concluded that job satisfaction and commitment to the team are factors that have a direct and positive effect on collective entrepreneurship.     

A proposed configurable approach for recommendation systems via data mining techniques

This study presents a configurable approach for recommendations which determines the suitable recommendation method for each field based on the characteristics of its data, the method includes determining the suitable technique for selecting a representative sample of the provided data. Then selecting the suitable feature weighting measure to provide a correct weight for each feature based on its effect on the recommendations. Finally, selecting the suitable algorithm to provide the required recommendations. The proposed configurable approach could be applied on different domains. The experiments have revealed that the approach is able to provide recommendations with only 0.89 error rate percentage.     

Performance trends in the construction industry worldwide: an overview of the turn of the century

This paper presents an exploratory study to assess the efficiency level of construction companies worldwide, exploring in particular the effect of location and activity in the efficiency levels. This paper also provides insights concerning the convergence in efficiency across regions. The companies are divided in three regions (Europe, Asia and North America), and in the three main construction activities (Buildings, Heavy Civil and Specialty Trade). We analyze a sample of 118 companies worldwide between 1995 and 2003. Data envelopment analysis is used to estimate efficiency, and the Malmquist index is applied for the evaluation of productivity change. Both methods were complemented by bootstrapping to refine the estimates obtained. A panel data truncated regression with categorical regressors is used to explore the impact of location and activity in the efficiency levels. The results reveal that the efficiency of North American companies is higher than the European and Asian counterparts. Other important conclusion points to a convergence in efficiency levels across regions as in North America productivity remains stable, whereas in Asia and Europe productivity improves.     

Qualitative/quantitative integration in the inductive observational study of interactive behaviour: impact of recording and coding among predominating perspectives

A strong dichotomy has traditionally been established between qualitative and quantitative approaches. This question has been the subject of intense debate from a methodological point of view, and in recent years there are clear signs that the conflict is being overcome; nevertheless, we are still some way from a genuine position of complementarity and integration, and the issue remains to be considered in the process of theorization along the tortuous path that leads from the particular to the general. The proposal in this article takes a further step forward as regards this question, this time with respect to the study of interactive behaviour. The key is once again the consideration of a “complete unit” of analysis, but the logic of the observational methodology process enables the perspectives to be sequenced: the study begins with a predominantly qualitative approach before subjecting the data to a given type of recording (through the important support of field formats) and coding (preferably computerized), thus producing a matrix of formally interchangeable data; finally, the criterion is reversed and the study continues under a predominantly quantitative perspective.
