The house-money effect, understood as people’s tendency to be more daring with easily-gotten money, is a behavioral pattern that poses questions about the external validity of experiments in economics: to what extent do people behave in experiments like they would have in a real-life situation, given that they play with easily-gotten house money? We ran an economic experiment with 122 students to measure the house-money effect on their risk preferences. They received an amount of money with which they made risky decisions involving losses and gains; a randomly selected treatment group received the money 21 days in advance and a control group got it the day of the experiment. From a simple calculation we found that participants in the treatment group only spent on average approximately 35 % of their cash in advance. The data confirms the well documented results that men are more tolerant to risk than women, and that individuals in general are more risk tolerant towards losses than towards gains. With our preferred specification, we find a mean CRRA risk aversion coefficient of 0.34, with a standard deviation of 0.09. Furthermore, if subjects in the treatment group spent 35 % of the endowment their CRRA risk aversion coefficient is higher than that of the control group by approximately 0.3 standard deviations. We interpret this result as evidence of a small and indirect house money effect operating though the amount of the cash in advance that was actually spent. We conclude that the house money effect may play a small role in decisions under uncertainty, especially when involving losses. Our novel design, however, could be used for other domains of decision making both in the lab and for calibration of economic models used in micro and macroeconomics.

The relation between wage growth and the reconstruction of the labor movement in Spain, during the developmentalist Francoist regime (1957-1975), has been controversial. Applying the power resources theory in order to explain wage growth, this paper argues that the rise of the labor share was the result of the increased bargaining power of workers in spite of repressive policies of the Francoist government. The action of new trade unionism mobilized the following power resources. First, the structural power increased as a consequence of techno-economics transformations of Fordism and a generational change of the labor force. Second, the associational power increased due to new organizational forms, with more democratic modes of collective action and combining clandestine and legal actions, and the reappearance of collective bargaining with the Law of Collective Bargaining Agreements of 1958. These political opportunities opened up the possibility to the new trade unionist of developing the strategy of entryism that served as the driving force for worker mobilization.

Consequently, the new trade unionists could mobilize their power resources in the three spheres, exchange, production, and politics, as a strategy by accelerating collaborative action, establishing a discursive and cultural framework, and allowing the articulation of the different trade union actions. In this way, internal solidarity was favored when a collective agreement was negotiated at the company or sector level (and not an individual contract, as it has been to date), due to the links with the social activities characteristic of the paternalistic management of labor relations and the presence of anti-Francoist organizations, the “network embeddedness” was strengthened. In turn, the successes in the consequence of wage increases and solidarity with other workers who were suffering repression increased the narrative resources that frame union actions. All this made it possible to counterbalance in part for the restrictions imposed by the dictatorship, which weakened the structural power of workers in the political sphere.

The main contribution to the existing knowledge on the issue consists in explaining the apparent paradox between the wage policy of the Francoist government (oriented towards wage restriction) and the increase in labor share. This also serves to understand how labor markets and the wage-setting mechanism worked from a historical point of view. As a corollary, the previous analysis implies that the most important factor was the ability to mobilize workers successfully. The union strategy that combined democratic instruments of representation (assemblies) with clandestine and legal actions served as a catalyst for other productive and social changes. This reflects the primacy of the action of social actors for the worker mobilization theory.

This article analyses from a Keynesian approach the effect of wage devaluation on the Spanish labour market during the Great Recession post-2008. It challenges the pro-flexibility literature, which attributes to labour relations reforms the prevention of larger job destruction in the recession and a larger reduction in unemployment during the subsequent expansion. Instead, we examine the role of wage devaluation in the operation of Okun’s law and gross domestic product, using an extended version of the Bhaduri–Marglin model. We find that wage devaluation has not significantly modified Okun’s law and that through its impact on income distribution, the unemployment rate rose by 1.9 percentage points. We therefore provide evidence for the negative effect of wage devaluation on gross domestic product and the positive effect on the unemployment rate.

The burden of depression is increasing worldwide, specifically in older adults. Unhealthy dietary patterns may partly explain this phenomenon. In the Spanish PREDIMED-Plus study, we explored (1) the cross-sectional association between the adherence to the Prime Diet Quality Score (PDQS), an a priori-defined high-quality food pattern, and the prevalence of depressive symptoms at baseline (cross-sectional analysis) and (2) the prospective association of baseline PDQS with changes in depressive symptomatology after 2 years of follow-up. After exclusions, we assessed 6612 participants in the cross-sectional analysis and 5523 participants in the prospective analysis. An energy-adjusted high-quality dietary score (PDQS) was assessed using a validated FFQ. The cross-sectional association between PDQS and the prevalence of depression or presence of depressive symptoms and the prospective changes in depressive symptoms were evaluated through multivariable regression models (logistic and linear models and mixed linear-effects models). PDQS was inversely associated with depressive status in the cross-sectional analysis. Participants in the highest quintile of PDQS (Q5) showed a significantly reduced odds of depression prevalence as compared to participants in the lowest quartile of PDQS (Q1) (OR (95 %) CI = 0·82 (0·68, 0·98))). The baseline prevalence of depression decreased across PDQS quintiles (Pfor trend = 0·015). A statistically significant association between PDQS and changes in depressive symptoms after 2-years follow-up was found (β (95 %) CI = −0·67 z-score (–1·17, −0·18). A higher PDQS was cross-sectionally related to a lower depressive status. Nevertheless, the null finding in our prospective analysis raises the possibility of reverse causality. Further prospective investigation is required to ascertain the association between PDQS and changes in depressive symptoms along time.

Trichomonas vaginalis induces cellular damage to the host cells (cytotoxicity) through the proteolytic activity of multiple proteinases of the cysteine type (CPs). Some CPs are modulated by environmental factors such as iron, zinc, polyamines, etc. Thus, the goal of this study was to assess the effect of glucose on T. vaginalis cytotoxicity, proteolytic activity and the particular role of TvCP2 (TVAG_057000) during cellular damage. Cytotoxicity assays showed that glucose-restriction (GR) promotes the highest HeLa cell monolayers destruction (~95%) by trichomonads compared to those grown under high glucose (~44%) condition. Zymography and Western blot using different primary antibodies showed that GR increased the proteolytic activity, amount and secretion of certain CPs, including TvCP2. We further characterized the effect of glucose on TvCP2. TvCP2 increases in GR, localized in vesicles close to the plasma membrane and on the surface of T. vaginalis. Furthermore, pretreatment of GR-trichomonads with an anti-TvCP2r polyclonal antibody specifically reduced the levels of cytotoxicity and apoptosis induction to HeLa cells in a concentration-dependent manner. In conclusion, our data show that GR, as a nutritional stress condition, promotes trichomonal cytotoxicity to the host cells, increases trichomonad proteolytic activity and amount of CPs, such as TvCP2 involved in cellular damage.

The potential of a mass asteroid impact on Earth to disturb the chemosynthetic communities at global scale is discussed. Special emphasis is made on the potential influence on anammox communities and their implications in the nitrogen biogeochemical cycle. According to our preliminary estimates, anammox communities could be seriously affected as a consequence of global cooling and the large process of acidification usually associated with the occurrence of this kind of event. The scale of affectations could vary in a scenario like the Chicxulub as a function of the amount of soot, depth of the water column and the deposition rate for sulphates assumed in each case. The most severe affectations take place where the amount of soot and sulphates produced during the event is higher and the scale of time of settlements for sulphates is short, of the order of 10 h. In this extreme case, the activity of anammox is considerably reduced, a condition that may persist for several years after the impact. Furthermore, the impact of high levels of other chemical compounds like sulphates and nitrates associated with the occurrence of this kind of event are also discussed.

We present studies using different observational techniques, along different frequencies, aiming to resolve and investigate jets, outflows, as well as compact and innermost regions of asymmetric planetary nebulae (PNe) and objects in transition to PN. All the information gathered allow us to explore the kinematics and other important properties of the structures that play a crucial role in the shaping of complex PNe morphologies, in particular, we explore the role of disks/tori as collimating engine of extreme axisymmetric PNe.

Tierra del Fuego represents the southernmost limit of human settlement in the Americas. While people may have started to arrive there around 10 500 BP, when it was still connected to the mainland, the main wave of occupation occurred 5000 years later, by which time it had become an island. The co-existence in the area of maritime hunter-gatherers (in canoes) with previous terrestrial occupants pre-echoes the culturally distinctive groups encountered by the first European visitors in the sixteenth century. The study also provides a striking example of interaction across challenging natural barriers.
