Does deregulation decrease unemployment? An empirical analysis of the Spanish labour market

Spain underwent two major labour reforms in 2010 and 2012 under the assumption that deregulating the labour market and decentralizing collective bargaining would automatically reduce unemployment (deregulation hypothesis). This article highlights the impact of demand and the sectoral structure of the economy to explain the behaviour of this variable (structural hypothesis). Analysing subnational panel data, the authors assess the capacity of these two hypotheses to explain unemployment trends. Their results cast doubt on the deregulation hypothesis and indicate the importance of cyclical and structural factors.     

Is the trend to publish reviews and clinical trials related to the journal impact factor? Analysis in dentistry field

ABSTRACT

It is generally accepted that the Journal Impact Factor is a quality criterion. The objective was to determine the evolution along the period 2010–2016 of number of different types of papers, reviews and clinical trials, published by dental journals, as well as if they are related with the quartile occupied in the Journal Impact Factor 2017 ranking. To this end, ten journals per quartile belonging to the field Dentistry, Oral Surgery and Medicine in the 2017 Journal Citation Reports were randomly selected. For each journal and year, the total number of narrative reviews, systematic reviews (with and without meta-analysis), meta-analysis, clinical trials and randomized controlled trials were obtained from Pubmed. To achieve our goal, the slope of these variables over time was estimated using the least squares method, after which one-way analysis of variance of mean values was performed. In Dentistry, the journals of the top quartiles show a trend to publish increasing amounts of systematic reviews and meta-analysis, than the ones of the third and fourth quartile. On the other hand, globally, there was virtually no increase in narrative reviews, clinical trials and randomized controlled trial. Possible causes of this behavior are also discussed in this article.     

Personal identity and social identity: two different processes or a single one? / Identidad personal e identidad social. ¿Dos procesos diferentes o uno solo?

Abstract

Personal identity, or the definition of oneself in terms of personal idiosyncratic attributes, and social identity, or the definition of oneself in terms of affiliations with different categories or groups, have often been examined as two separate phenomena in the psychosocial literature. However, there are at least two theories which have deliberately researched the relationship between the two. One of these theories has done so for almost five decades (Social Identity Theory), while the alternative approach (Identity Fusion, or the visceral sense of oneness with the group) began to be developed less than one decade ago. The purpose of this special issue is to survey how approaches grounded upon both theories have attempted to explain some individuals’ extreme behaviours for their group. It also includes studies that examine the origins of identity fusion, the processes that relate it with extreme behaviour (such as the extension of familial ties to groups or the acceptance of violence), as well as a subtle demonstration of how group identity can affect interpersonal relationships.     

The Influence of Water Access in Subjective Well-Being: Some Evidence in Yucatan, Mexico

The literature on happiness or subjective well-being has explored the determinants of happiness without taking into consideration the role that water plays. In this paper we attempt to draw attention to water in subjective well-being studies. Approximately one hundred million people do not have access to water. A lack of clean water causes diseases such as diarrhea and cholera, responsible for around 5% of the total deaths in the world. Access to water should therefore be a necessary asset in life. In order to consider access to water, we estimate its influence on subjective well-being using data from rural Yucatan, Mexico. Residents in Yucatan suffer from low quality access to water and there are also imperfections in the management of the service, such as water cuts. We estimate the influence of water on subjective well-being, finding a positive and significant relationship. In a second stage of the research, we relate water access variables to subjective well-being, the health and the water domain of life, finding significant results. These results make it possible to formulate political measures concerning access to water and happiness maximization. We demonstrate that access to water is important for well-being in Yucatan and might be important in many other places; we therefore encourage future research to contemplate water satisfaction and water variables in their analysis.

When Knowledge Is Not Enough: Elements to Strengthen Intercultural Sensitivity Among Professionals of Social Services in Andalusia (Spain)

ABSTRACT.

This study examines social services delivery in Andalusia, Spain, to determine the degree of cultural adaptation of its workers, given the important migratory flows taking place in the region during recent years. This study investigates the main characteristics of those workers with a high level of intercultural sensitivity (IS) and their cultural competences. The survey included 298 professionals with a validated IS scale along with questions related to the degree of intercultural contact and competence. A series of scales for the IS levels was created, and correlation analyses were carried out depending on the variables used. Results revealed high levels of self-attributed cultural competence and training as well as low levels of awareness and motivation for intercultural encounters. Theoretical knowledge appeared to be the only aspect in correlation with all dimensions of IS. Important deficits have been also observed when examining the type and intensity of contact among professionals and people of foreign origin. This highlights the need to transform knowledge in culturally adapted responses. Future research is necessary to deepen knowledge on how these aspects affect professional interventions.     

Property Size and Land Cover Change in the Brazilian Amazon

This paper considers the size of a farmer’s property as a key variable influencing land cover and land cover change in rural areas of developing countries. Data from 126 rural familial properties in the region around the city of Santarém, Pará, in the Brazilian Amazon, indicate that property size is important for understanding the trajectories of land cover change. Past research has focused on the distinction between small family farms and large capitalized farms, arguing that family farmers have a higher deforestation intensity, or on estimating the strength of the effect of property size relative to economic or demographic factors. This paper shows that larger familial properties are able both to retain a larger area in forest and to have long enough cycles of use and fallow to allow previously used land to become forested again. Based on these analyses and discussion, we argue that land use and land cover research must consider property size as an organizing principle in order to better comprehend the reciprocal relationship between population and environment in frontier areas of the Brazilian Amazon and other rural landscapes.     

Bayesian acceptance sampling plans following economic criteria: An application to paper pulp manufacturing

The main purposes of this paper are to derive Bayesian acceptance sampling plans regarding the number of defects per unit of product, and to illustrate how to apply the methodology to the paper pulp industry. The sampling plans are obtained following an economic criterion: minimize the expected total cost of quality. It has been assumed that the number of defects per unit of product follows a Poisson distribution with process average 5 , whose prior information is described either for a gamma or for a non- informative distribution. The expected total cost of quality is composed of three independent components: inspection, acceptance and rejection. Both quadratic and step-loss functions have been used to quantify the cost incurred for the acceptance of a lot containing units with defects. Combining the prior information on 5 with the loss functions, four different sampling plans are obtained. When the quadratic-loss function is used, an analytical relation between the optimum settings of the sample size and the acceptance number is derived. The robustness analysis indicates that the sampling plans obtained are robust with respect to the prior distribution of the process average as well as to the misspecification of its mean and variance.
