ABSTRACT:

In this study, a method will be developed and applied for estimating biological migration parameters of the biomass of a fishery resource by means of a decision analysis of the spatial behavior of the fleet. First, a model of discrete selection is estimated, together with patch capture function. This will allow estimating the biomass availability on each patch. In the second regression, values of biomass are used in order to estimate a model of biological migration between patches. This method is proven in the Chilean jack mackerel fishery. This will allow estimating statistically significant migration parameters, identifying migration patterns.

ABSTRACT:

The aim of this research is to validate the Family Quality of Life Scale (FQLS) in a Chilean population and to analyze the factor structure (scope) of this research tool through the critical area map. Cross-sectional, correlational, and causal study was carry on 316 families. The Spanish version of the FQSL was used. An exploratory and confirmatory factor analysis was conducted. Results showed Cronbach´s alpha for the FQLS subscales on Importance rate was 0.884 and on Satisfaction 0.891. The exploratory factor analysis found five dimensions for both categories, and the confirmatory factor analysis showed factor loadings greater than 0.5 for each dimension. Regarding discriminant validity, the cross-loadings varied between 0.64 to 0.97 on Importance and 0.62 to 0.98 on Satisfaction. In relation to convergent validity, each dimension reached a variance above 0.5. Conclusions of the study proved a reliable and valid tool to measure features of family quality of life in a Chilean population. The instrument has high levels of internal consistency and suitable discriminant and convergent validity.

ABSTRACT:

There is abundant empirical evidence supporting the relationship between cooperation and innovative entrepreneurial activity, but the conversation continues to be limited to the context of developing countries. This study contributes to the academic debate on this topic with an empirical evaluation of the effect of cooperation networks on innovation, using Chile in Latin America as a case study. Furthermore, while previous studies mainly refer to technological innovations in a particular industrial sector, in this paper we will build an innovation measurement system that incorporates both technological and non-technological activities among diverse industrial sectors. Upon applying cross-sectional data from a national survey on innovation in a developing firm from two different years to a zero-inflated negative binomial regression, we found that a business that reports on cooperation conducts more innovative activities per year compared to one that does not. The type of agent that a business cooperates with is also relevant in this context; other businesses, clients, and consultants showed stronger and more stable results than other types of agents. This evidence is relevant as it presents new information about the importance of the type of agent that a business cooperates with in the context of developing countries.

ABSTRACT

Despite evidence highlighting the multiple benefits that liberalization can have in the agricultural sector, agricultural protectionism is abundant, especially in developing countries. Chile provides an interesting case on this topic because it implemented an aggressive liberalization in the agricultural sector during the 1970s and 1980s. This paper analyzes the impact of farm protectionism on the use of agricultural inputs in Chile. To do this, we estimated partial elasticities of substitution by incorporating government protectionism as a factor for agricultural production. Our findings reveal that increased protectionism decreases agricultural labor and promotes the use of fixed capital. In contrast, protectionism has no effect on the use of working capital and land. This information shows a clear transference from the government to farmers. Furthermore, our results are useful for anticipating the effects that varying levels of government protectionism can have on the Chilean agricultural sector over time.
