Summary
Categorization – assimilating objects to psychological equivalence classes – is a crucial cognitive capacity that has always enhanced vertebrate fitness. This chapter reviews from a primate perspective the state of knowledge in comparative categorization’s subdomains: prototypes, exemplars, rules, and abstractions. Primate studies have made a profound contribution to the prototype-exemplar debate – essentially resolving it. They have illuminated the evolutionary emergence of a cognitive capacity for category rules, illuminating also the emergence of humans’ explicit-declarative cognition. In this area, primates appear as a pivotal transitional form. In the literature on abstract concepts (e.g., Same-Different), primate studies highlight the differences in cognitive capacities across vertebrate lines. The review will demonstrate the crucial role of a fitness/ecological perspective in understanding categorization as an adaptive, information-processing capability. It will raise important questions about the similarity structure of natural (and unnatural) kinds and categories. It will show strong continuities between human and animal cognition, but important discontinuities as well. In all the subdomains, the primates have been extraordinary behavioral ambassadors to the broader field of categorization.

Land use intensification imposes selective pressures that systematically change the frequency of wild population phenotypes. Growing evidence is biased towards the comparison of populations from discrete categories of land uses, ignoring the role of landscape emerging properties on the phenotype selection of wild fauna. Across the largest urban–rural gradient of the Colombian Orinoquia, we measured ecomorphological traits of 216 individuals of the flat-faced fruit-eating bat Artibeus planirostris. We did this to evaluate the scale of effect at which landscape transformation better predicts changes in phenotype and abundance of an urban-tolerant species. Forest percentage at 1.25 km was the main predictor affecting negatively bat abundance and positively its wing aspect ratio and body mass. Landscape variables affected forearm length at all spatial scales, this effect appeared to be sex-dependent, and the most important predictor, forest percentage at 0.5 km, had a negative effect on this trait. Our results indicate that landscape elements and spatial scale interact to shape ecomorphological traits and the abundance of A. planirostris. Interestingly, the scale of effect coincided at 1.25 km among all biological responses, suggesting that species’ abundance can be linked to the variation on phenotype under different environmental filters across landscape scenarios.

Introduction
It is hypothesized that in the etiology of schizophrenia genetic and environmental factors are involved. Between the environmental events linked to the causation of this condition an inmune dysfunction has been described. First degree biological relatives of people with schizophrenia also have an incrased incidence of autoimmune diseases.
ObjectivesThe aim of this work was to examine the serum levels of proinflammatory cytokines (IL-1β, sIL-2R IL-6, IL-12p70, TNF-α and IFN-γ) as well as of anti-inflammatory cytokines (IL-4 and IL-10) in male patients with schizophrenia and in their first degree-biological relatives.
MethodsBlood samples were obtained from patients with a diagnosis of schizophrenia in a stable psychophatological condition (n = 36), first degree biological relatives of those patients and a healthy control group (n = 26). Serum interleukins were analyzed using a commercial ELISA preparation (Bender MedSystems). We used non-parametric test for statistical analysis.
ResultsPatients with schizophrenia showed significantly higher serum levels of proinflammatory cytokines (sIL-2R, IL-6, TNF-α, IFN-γ and IL12-p70) and lower serum levels of the anti-inflammatory cytokine IL-4 than in the healthy control group. The unaffected first-degree relatives showed changes in proinflammatory cytokines (sIL-2R, IL-6 and TNF-α,) in the same way as the corresponding schizophrenia patients, but at a lower level than the healthy control group.
ConclusionsOurs findings suggest that sIL-2R, IL-6 and TNF-a may be biologic vulnerability markers for psychiatric disorders and also these alterations might have an hereditably pattern.

Introduction
Attachment is an innate programming whereby a child seeks for security. There is scientific and empirical evidence that insecure attachment is usual in eating disorder patients [1].
ObjectivesTo highlight the relevance of attachment between child and caregivers, as well as its significance in therapeutic approach.
MethodsA 17-year-old girl hospitalized after attending to emergency department due to fainting. BMI: 12.89. She reports restrictive behavior since age 11 that her mother regards as “child issues”. Divorced parents, she grew up with her mother, diagnosed of hypochondria, who mentions not understanding why she is not the one who is hospitalized.
ResultsDuring hospitalization, she turned 18-years-old. Guardianship of her younger siblings was removed to her mother. She had a secure relationship with her 24-year-old sister, so she decided to move in with her. Later on, she had a positive progress, maintaining the gained weight and mood stability, although cognitive distortions persist.
ConclusionsAmong developmental and maintaining factors of eating disorders, impaired attachment is becoming increasingly interesting. Even though the main goal of treatment is weight restoration, exploring attachment patterns can facilitate to achieve that aim. This clinical case emphasizes the importance of attachment in eating disorders among child and young adults.

Introduction
Suicide is the deliberate act of take off life to itself. According to WHO, more than one million people commit suicide every year.
GoalsCompare data of suicide attempts between 1996 and 2014 in the University Hospital of Valladolid. Influence of the economic crisis on suicide data. Expose the risk factors. Provide prevention strategies.
Material and methodsWe have performed a study of epidemiological surveillance collecting descriptive data of suicide attempts; using the same methodology as in 1996. The variables studied were: sex, age, day, month, residence, method, personal status, education, employment status, religious believes, family history of suicide, psychiatric history and family and personal psychiatric history.
ResultsIncrease in the rate of suicide attempts 27%. Distribution by sex is similar, but in 2014, a higher proportion was observed in males. The percentage of women is significantly higher than that of men in the group of teenagers (10–19 years old) (20% women vs. 4.5% of men; P = 0.005); 83.5% have a psychiatric diagnosis (54.2% of them have a depressive disorder). Unemployment and economic problems stand out as environmental stressors in 2014. The main suicide method used in Valladolid is the hanging, and the second method used is the precipitation.
ConclusionsThe primary, secondary and tertiary prevention strategies are very important. Suicide is the major cause of mortality in the young age group (15–24 years old). Mortality in the general population has been on a downward trend; but suicide rates per 100,000 population has remained stable over the last decade.

Post-Asymptotic giant branch (post-ABG) sources with high-velocity spectral features of H2O maser emission detected toward their circumstellar envelopes (CSEs) are known as Water Fountain (WF) nebulae. These are low- or intermediate-mass Galactic stellar sources that are undergoing the late stages of an intense mass-loss process. The velocity and the spatial distribution of the H2O maser spectral features can provide information about the kinematics of the molecular gas component of their CSEs. Hence, observational studies toward WF nebulae could help to better understand the formation of the asymmetric structures (hundred to thousand AUs) commonly seen toward Planetary nebulae (PNe). Here we present preliminary results of observations done toward the WF IRAS 15445-5449 using the Australia Telescope Compact Array (ATCA) and the Very Large Telescope (SINFONI/VLT). Assuming that the pumping of the H2O maser transitions is a consequence of shocks between different velocity winds, the spatial distribution of the emission shed light on the scales of the regions affected by the propagation of the shock-fronts.

We present the results of the first detection of submillimeter water maser emission toward water-fountain nebulae. Using APEX we found emission at 321.226 GHz toward two sources: IRAS 18043−2116, and IRAS 18286−0959. The submillimeter H2O masers exhibit expansion velocities larger than those of the OH masers, suggesting that these masers, similarly to the 22 GHz masers, originate in fast bipolar outflows. The 321 GHz masers in IRAS 18043−2116 and IRAS 18286−0959, which figure among the sources with the fastest H2O masers, span a velocity range similar to that of the 22 GHz masers, indicating that they probably coexist. The intensity of the submillimeter masers is comparable to the 22 GHz masers, implying that the kinetic temperature of the region where the masers originate is Tk>1000 K. We propose a simple model invoking the passage of two shocks through the same gas that creates the conditions for explaining the strong high-velocity 321 GHz masers coexisting with the 22 GHz masers in the same region.

The Calar Alto Legacy Integral Field Area (CALIFA) project is an ongoing 3D spectroscopic survey of 600 nearby galaxies of all kinds. This pioneer survey is providing valuable clues on how galaxies form and evolve. Processed through spectral synthesis techniques, CALIFA datacubes allow us to, for the first time, spatially resolve the star formation history of galaxies spread across the color-magnitude diagram. The richness of this approach is already evident from the results obtained for the first ~ 1/6 of the sample. Here we show how the different galactic spatial sub-components (“bulge” and “disk”) grow their stellar mass over time. We explore the results stacking galaxies in mass bins, finding that, except at the lowest masses, galaxies grow inside-out, and that the growth rate depends on a galaxy's mass. The growth rate of inner and outer regions differ maximally at intermediate masses. We also find a good correlation between the age radial gradient and the stellar mass density, suggesting that the local density is a main driver of galaxy evolution.

Once ALMA full polarization capabilities are offered, (sub-)mm polarization studies will enter a new era. It will become possible to perform detailed studies of polarized maser emission towards for example massive star forming regions and late-type stars such as (post-) Asymptotic Giant Branch stars and young Planetary Nebulae. In these environments, SiO, H2O and HCN are molecules that can naturally generate polarized maser emission observable by ALMA. The maser polarization can then be used to derive the strength and morphology of the magnetic field in the masing regions. However, in order to derive, in particular, the magnetic field orientation from maser linear polarization, a number of conditions involving the rate of stimulated emission, molecular state decay and Zeeman splitting need to be satisfied. In this work, we discuss these conditions for the maser transitions in the ALMA frequency range and highlight the optimum transitions to further our understanding of star formation and evolved star magnetic fields.

We present the morphology and linear polarization of the 22-GHz H2O masers in the high-velocity outflow of two post-AGB sources, d46 (IRAS 15445–5449) and b292 (IRAS 18043–2116). The observations were performed using The Australia Telescope Compact Array. Different levels of saturated maser emission have been detected for both sources. We also present the mid-infrared image of d46 overlaid with the distribution of the maser features that we have observed in the red-shifted lobe of the bipolar structure. The relative position of the observed masers and a previous radio continuum observation suggests that the continnum is produced along the blue-shifted lobe of the jet. It is likely due to synchrontron radiation, implying the presence of a strong magnetic field in the jet. The fractional polarization levels measured for the maser features of d46 indicate that the polarization vectors are tracing the poloidal component of the magnetic field in the emitting region. For the H2O masers of b292 we have measured low levels of fractional linear polarization. The linear polarization in the H2O maser region of this source likely indicates a dominant toroidal or poloidal magnetic field component.

We present the results from the spectroscopic follow-up of WR140 (WC7 + O4-5) during its last periastron passage in january 2009. This object is known as the archetype of colliding wind binaries and has a relatively large period (≃8 years) and eccentricity (≃0.89). We provide updated values for the orbital parameters, new estimates for the WR and O star masses and new constraints on the mass-loss rates.
