Aldeas abandonadas de Galicia: la cartografía del abandono: aproximación a Pontevedra y sus comarcas

[Resumen] Galicia cuenta con más de treinta mil entidades singulares de población, que suponen casi el cincuenta por ciento del total de territorio español. Desde mediados del siglo pasado se ha producido un fenómeno de abandono de los núcleos rurales, un hecho que parece inexorable y que desde el cambio de siglo se ha acelerado. El complejo sistema de asentamiento gallego añade un matiz de dificultad para comprender el proceso de despoblación que afecta a toda la comunidad. Para una aproximación a este fenómeno se analizarán los datos arrojados por las fuentes estadísticas como el Instituto Galego de Estatística (IGE) para su posterior representación gráfica configurando así una cartografía del abandono. Este hecho no se puede entender de manera aislada, sino que se debe concebir como un todo, por ello, se aborda el análisis del marco gallego, para posteriormente concretar una región determinada como es la provincia de Pontevedra.[Resumo] Galicia conta con máis de trinta mil entidades singulares de poboación, que supoñen case o cincuenta por cento do total do territorio español.

Since the middle of the last century there has been a process of abandonment of the rural nuclei, a fact that seems inexorable and that since the turn of the century has accelerated. The complex Galician settlement system adds a nuance of difficulty to understand the depopulation process that affects the entire community. For an approximation to this phenomenon, the data produced by statistical sources such as the Galician Statistics Institute (IGE) will be analyzed for later graphic representation, configuring a cartography of abandonment. This fact cannot be understood in isolation, but must be conceived as a whole, therefore, the analysis of the Galician framework is approached, to later specify a specific region such as the province of Pontevedra.Traballo fin de grao (UDC.ETSA).

Boredom-like states in mink and their behavioural correlates: a replicate study

Scientists and laypeople have long expressed concern that animals in non-enriched, unchanging environments might experience boredom. However, this had attracted little empirical study: the state is difficult to assess without verbal self-reports, and spontaneous behavioural signs of boredom can vary in humans, making it hard to identify signs likely to be valid in other species. We operationally define boredom as a negative state that causes an increased, generalised interest in diverse stimuli. Previously, we demonstrated that this state existed in mink housed in non-enriched cages, compared to those in preferred, stress-reducing enriched enclosures; and that this heightened interest in stimuli positively correlated with time spent lying still but awake, while negatively correlating with locomotor stereotypic behaviour. However, these results needed replication. The current study tested for the same effects, in a new cohort of 20 male mink, by presenting 11 stimuli ranging from those predicted to typically be aversive (e.g. predator cues) to those predicted to be rewarding (e.g. food rewards; moving objects to chase). Where housing treatments differed, non-enriched mink were again more interested in the stimuli presented, spending longer oriented towards and in contact with them (e.g. for aversive stimuli: F1,9=6.27, p=0.034 and F1,9=8.24, p=0.019, respectively). Lying still but awake again correlated with interest in the stimuli (shorter latencies to contact rewarding stimuli: F1,17=3.70, p=0.036; in enriched mink only, more time oriented to and in contact with all stimuli: F1,8=9.49, p=0.015 and F1,8=15.9, p=0.004). In contrast, the previous correlations with stereotypic behaviour were not replicated. We therefore conclude that mink housed in non-enriched cages likely experience boredom-like states, and that time spent lying still while awake could potentially be used as a cage-side indicator of these states. We also suggest how future researchers might address further fundamental and practical questions about animal boredom, in mink and other species

Comparative effectiveness of intracranial hypertension management guided by ventricular versus intraparenchymal pressure monitoring:a CENTER-TBI study

Objective: To compare outcomes between patients with primary external ventricular device (EVD)–driven treatment of intracranial hypertension and those with primary intraparenchymal monitor (IP)–driven treatment. Methods: The CENTER-TBI study is a prospective, multicenter, longitudinal observational cohort study that enrolled patients of all TBI severities from 62 participating centers (mainly level I trauma centers) across Europe between 2015 and 2017. Functional outcome was assessed at 6 months and a year. We used multivariable adjusted instrumental variable (IV) analysis with “center” as instrument and logistic regression with covariate adjustment to determine the effect estimate of EVD on 6-month functional outcome. Results: A total of 878 patients of all TBI severities with an indication for intracranial pressure (ICP) monitoring were included in the present study, of whom 739 (84%) patients had an IP monitor and 139 (16%) an EVD. Patients included were predominantly male (74% in the IP monitor and 76% in the EVD group), with a median age of 46 years in the IP group and 48 in the EVD group. Six-month GOS-E was similar between IP and EVD patients (adjusted odds ratio (aOR) and 95% confidence interval [CI] OR 0.74 and 95% CI [0.36–1.52], adjusted IV analysis). The length of intensive care unit stay was greater in the EVD group than in the IP group (adjusted rate ratio [95% CI] 1.70 [1.34–2.12], IV analysis). One hundred eighty-seven of the 739 patients in the IP group (25%) required an EVD due to refractory ICPs. Conclusion: We found no major differences in outcomes of patients with TBI when comparing EVD-guided and IP monitor–guided ICP management. In our cohort, a quarter of patients that initially received an IP monitor required an EVD later for ICP control. The prevalence of complications was higher in the EVD group. Protocol: The core study is registered with ClinicalTrials.gov, number NCT02210221, and the Resource Identification Portal (RRID: SCR_015582).</p

Benefits of a ball and chain: simple environmental enrichments improve welfare and reproductive success in farmed American mink (Neovison vison)

Can simple enrichments enhance caged mink welfare? Pilot data from 756 sub-adults spanning three colour-types (strains) identified potentially practical enrichments, and suggested beneficial effects on temperament and fur-chewing. Our main experiment started with 2032 Black mink on three farms: from each of 508 families, one juvenile male-female pair was enriched (E) with two balls and a hanging plastic chain or length of hose, while a second pair was left as a non-enriched (NE) control. At 8 months, more than half the subjects were killed for pelts, and 302 new females were recruited (half enriched: ‘late E’). Several signs of improved welfare or productivity emerged. Access to enrichment increased play in juveniles. E mink were calmer (less aggressive in temperament tests; quieter when handled; less fearful, if male), and less likely to fur-chew, although other stereotypic behaviours were not reduced. On one farm, E females had lower cortisol (inferred from faecal metabolites). E males tended to copulate for longer. E females also weaned more offspring: about 10% more juveniles per E female, primarily caused by reduced rates of barrenness (‘late E’ females also giving birth to bigger litters on one farm), effects that our data cautiously suggest were partly mediated by reduced inactivity and changes in temperament. Pelt quality seemed unaffected, but E animals had cleaner cages. In a subsidiary side-study using 368 mink of a second colour-type (‘Demis’), similar temperament effects emerged, and while E did not reduce fur-chewing or improve reproductive success in this colour-type, E animals were judged to have better pelts. Overall, simple enrichments were thus beneficial. These findings should encourage welfare improvements on fur farms (which house 60-70 million mink p.a.) and in breeding centres where endangered mustelids (e.g. black-footed ferrets) often reproduce poorly. They should also stimulate future research into more effective practical enrichments

Two neurostructural subtypes: results of machine learning on brain images from 4,291 individuals with schizophrenia

Machine learning can be used to define subtypes of psychiatric conditions based on shared clinical and biological foundations, presenting a crucial step toward establishing biologically based subtypes of mental disorders. With the goal of identifying subtypes of disease progression in schizophrenia, here we analyzed cross-sectional brain structural magnetic resonance imaging (MRI) data from 4,291 individuals with schizophrenia (1,709 females, age=32.5 years±11.9) and 7,078 healthy controls (3,461 females, age=33.0 years±12.7) pooled across 41 international cohorts from the ENIGMA Schizophrenia Working Group, non-ENIGMA cohorts and public datasets. Using a machine learning approach known as Subtype and Stage Inference (SuStaIn), we implemented a brain imaging-driven classification that identifies two distinct neurostructural subgroups by mapping the spatial and temporal trajectory of gray matter (GM) loss in schizophrenia. Subgroup 1 (n=2,622) was characterized by an early cortical-predominant loss (ECL) with enlarged striatum, whereas subgroup 2 (n=1,600) displayed an early subcortical-predominant loss (ESL) in the hippocampus, amygdala, thalamus, brain stem and striatum. These reconstructed trajectories suggest that the GM volume reduction originates in the Broca's area/adjacent fronto-insular cortex for ECL and in the hippocampus/adjacent medial temporal structures for ESL. With longer disease duration, the ECL subtype exhibited a gradual worsening of negative symptoms and depression/anxiety, and less of a decline in positive symptoms. We confirmed the reproducibility of these imaging-based subtypes across various sample sites, independent of macroeconomic and ethnic factors that differed across these geographic locations, which include Europe, North America and East Asia. These findings underscore the presence of distinct pathobiological foundations underlying schizophrenia. This new imaging-based taxonomy holds the potential to identify a more homogeneous sub-population of individuals with shared neurobiological attributes, thereby suggesting the viability of redefining existing disorder constructs based on biological factors

Measuring collective action intention toward gender equality across cultures

Collective action is a powerful tool for social change and is fundamental to women and girls’ empowerment on a societal level. Collective action towards gender equality could be understood as intentional and conscious civic behaviors focused on social transformation, questioning power relations, and promoting gender equality through collective efforts. Various instruments to measure collective action intentions have been developed, but to our knowledge none of the published measures were subject to invariance testing. We introduce the gender equality collective action intention (GECAI) scale and examine its psychometric isomorphism and measurement invariance, using data from 60 countries (N = 31,686). Our findings indicate that partial scalar measurement invariance of the GECAI scale permits conditional comparisons of latent mean GECAI scores across countries. Moreover, this metric psychometric isomorphism of the GECAI means we can interpret scores at the country-level (i.e., as a group attribute) conceptually similar to individual attributes. Therefore, our findings add to the growing body of literature on gender based collective action by introducing a methodologically sound tool to measure collective action intentions towards gender equality across cultures
