The raise estimator estimation,inference, and properties

Several methods using different approaches have been developed to remedy the consequences of collinearity. To the best of our knowledge, only the raise estimator proposed by García et al. (2010 García, C.B., García, J., Soto, J. (2010). The raise method: An alternative procedure to estimate the parameters in presence of collinearity. Qual. Quantity 45(2):403–423.[Crossref], [Web of Science ®] , [Google Scholar]) deals with this problem from a geometric perspective. This article fully develops the raise estimator for a model with two standardized explanatory variables. Inference in the raise estimator is examined, showing that it can be obtained from ordinary least squares methodology. In addition, contrary to what happens in ridge regression, the raise estimator maintains the coefficient of determination value constant. The expression of the variance inflation factor for the raise estimator is also presented. Finally, a comparative study of the raise and ridge estimators is carried out using an example.     

Labor Mismatches: Effects on Wages and on Job Satisfaction in 17 OECD Countries

This study analyzes the effects of labor mismatches on wages and on job satisfaction in seventeen OECD countries by distinguishing between educational mismatch and skills mismatch. Using data from PIAAC, the results suggest that whereas educational mismatch shows greater effects on wages, the effects of labor mismatch on job satisfaction are generally better explained by skills mismatches. Both phenomena appear to be relevant for understanding the economic effects of labor mismatch and suggest that educational mismatch is not an accurate proxy for skills mismatch, mainly when the non-monetary effects of labor mismatch are addressed.     

Evaluation of the implementation of a socio-educational program with immigrant families: a case study

There exist an increasing number of studies that demonstrate the necessity to evaluate the processes which characterize a program and guarantee its implementation and evaluation. This paper deals with the implementation of a program designed to improve the acculturation of immigrant families in Spain (EU). Implementation followed a process that has proved successful in other settings, but is being applied here for the first time. Qualitative and quantitative measures are employed to assess each stage of implementation, with a particular emphasis on fidelity to program design. The intent was to guide effective revision of the program, and to establish it in a form that can be implemented on a larger scale.

Characterizations through reliability measures from weighted distributions

In this paper we obtain general characterizations of probability distributions from relationships between failure rate and mean residual life from the origin distribution and associated weighted distribution. Our characterization properties extend particular results given by Gupta and Keating (1986), Jain et al. (1989) and Asadi (1998). Using the theoretical results we obtain characterizations of some usual distributions. Received: December 7, 1998; revised version: May 10, 2000     

Manual bamboo cutting tool

The paper presents the development of a cutting tool guide, specifically for the harvest of bamboo. The development was made based on precepts of eco-design and ergonomics, for prioritizing the physical health of the operator and the maintenance of the environment, as well as meet specific requirements of bamboo. The main goal is to spread the use of bamboo as construction material, handicrafts, among others, from a handy, easy assembly and material available tool.

The impact of affectivity on the behaviour of Portuguese adolescents / El impacto de la afectividad en la conducta de los adolescentes portugueses

The theoretical literature about affectivity shows its influence over positive and negative behaviour. This study analyses the impact of affectivity on the behaviour of Portuguese adolescents, as this knowledge is considered relevant to promoting skills and decreasing risky behaviours in adolescents. A total of 696 students (M = 15.22 years old; SD = 1.4) participated in this study by responding to the PANAS-N (Positive and Negative Affect Schedule) and SDQ (Strengths and Difficulties Questionnaire). The former measures the level of affect while the latter measures prosocial behaviours, emotional symptoms and behavioural problems. The results showed that positive affect positively influences prosocial behaviour. Emotional symptoms and behaviour problems are negatively affected by positive affect, and positive symptoms and behaviours by negative affect. Moreover, boys had higher scores on behaviour problems, while girls had higher scores in prosocial behaviour and emotional symptoms. For these reasons, affectivity should be considered in programmes to reduce behaviour problems and emotional symptoms.     

Shocks and Spatial Regime Fades in Spain's International Migration Distribution

Using an exploratory space‐time analysis called spMorph, this article explores how the spatial distribution of international migration across the Spanish provinces has evolved over the period 1998‐2010. The chief advantage of this approach is that it permits the unambiguous identification of two key components in a spatial redistribution process, namely the shocks to the spatial distribution and the duration of regime fades. The results of the analysis show that administrative regions do not provide a reliable picture of the real dynamics in Spain's international migration distribution. In addition, the identification of two spatial shocks reveals the existence of three spatial regimes that consistently characterize the various phases that international migration has been through since the late 1990s.     

TOGETHER – A Couples’ Program to Improve Communication,Coping, and Financial Management Skills: Development and Initial Pilot‐Testing

The accumulated knowledge about the negative impact of financial strain on couple's relationship functioning and the magnitude of the latest economic downturn have brought together the fields of financial counseling and couples’ therapy. This article describes the development of a new interdisciplinary program that aims at helping couples under financial strain improve their financial management, communication, and dyadic coping skills. The article also reports the results from its initial pilot‐testing with data collected from 18 financially distressed couples before and after participation in the program and 3 months later. Results from repeated measures ANOVAs suggest that the program may help reduce both partners’ financial strain and the male negative communication and improve both partners’ financial management skills and strategies to cope together with financial strain, and the male relationship satisfaction. These findings together with the high satisfaction reported by participants regarding the structure and content of the sessions and homework suggest that this program may be a promising approach to help couples experiencing financial strain. Gender differences, clinical implications, and possibilities for further research are also discussed.
