The cyclical trend of local public service governance: evidence from urban water management in Spain

The level of public and private involvement in economic activity in societies has changed over time. One may talk about the existence of a cyclical trend in which the most important periods of public governance are replaced by periods in which private management dominates the situation. This phenomenon may also be observed in local areas. Some authors have pointed out the existence of an alternation in the provision of municipal services, resulting in periods dominated by governance compared to other stages dominated by private management. In order to illustrate this cyclical trend at local level, this paper intends to analyze the evolution of the governance of the Spanish water supply since the mid-nineteenth century to the present day. Recent evidence from the industry suggests the possibility that we may currently be witnessing a further change in the trend.: Local Government, urban water supply, privatization, municipalization

Intimate Partner Aggression Committed by Prison Inmates With Psychopathic Profile

[Abstract] Psychopathy and intimate partner aggression (IPA) are two concepts that usually appear concomitantly. Male violence toward women is often considered a psychopathic trait that sometimes involves the woman’s homicide by her partner and, at other times, attempted homicide. This phenomenon has been studied by conducting interviews following Hare’s model with 92 men incarcerated under a compliance regime in a Spanish prison (Córdoba). The results detected six explanatory factors of IPA as a result of attempted homicide or homicide: criminal past and delinquency, impulsivity, the need to stand out from others, lack of empathy, manipulation of others, and instability in partner relationships. The first two factors predict a occurrence of high scores on Hare’s Psychopathy Checklist. The results are discussed, and future lines of research are presented, especially focused on the concept of dehumanization and reveng

Physical Activity Practice, Sleeping Habits and Academic Achievement

There is a wide body of research that has identified the strong links between health behaviors and academic achievement. The media and official agencies strive to convey to schoolchildren and the public the need to show healthy lifestyles. However, it is striking that sleep habits have been considered in few occasions within healthy behaviors to be developed and promoted. Schools should encourage their students to be active because the effect of physical exercise will promote sleep and will positively affect the performance of academic tasks. Then, it is necessary to revitalize and establish the subject of Physical Education and Sport practice properly where the students can meet a minimum of 150 minutes of moderate-to-vigorous exercise per week. This approach will have a direct impact on the school children’s performance and health. Therefore, the key question is to decide whether educational centers must promote active lifestyles where sleep and exercise will be promoting or maintain schools where the body and body intelligence remain an irrelevant matter

Nuevos fotocatalizadores Sm2FeTaO7 y Sm2InTaO7 para la eliminación de contaminantes presentes en el agua

En esta investigación se reporta por primera vez la síntesis del óxido tipo pirocloro Sm2FeTaO7 por los métodos de reacción en estado sólido y sol-gel, así como el óxido Sm2InTaO7 mediante sol-gel. Los resultados de la caracterización estructural revelaron que el óxido Sm2FeTaO7 cristaliza en el sistema monoclínico con grupo espacial C2/c mientras que el óxido Sm2InTaO7 cristaliza en el sistema cúbico y grupo espacial Fd-3m. Para ambos materiales, cuando se utilizó el método sol-gel se obtienen materiales con propiedades morfológicas y superficiales diferentes, principalmente, en su tamaño de partícula y área superficial específica. La evaluación fotocatalítica mostró que el Sm2FeTaO7 es activo en la eliminación del colorante índigo carmín bajo condiciones reales de radiación solar. Mientras que, el Sm2InTaO7 es eficiente para reducir el ion Cr (VI) y degradar el colorante cristal violeta

Ac magnetic susceptibility of a molecular magnet submonolayer directly patterned onto a microSQUID sensor

We report the controlled integration, via Dip Pen Nanolithography, of monolayer dots of ferritin-based CoO nanoparticles (12 Bohr magnetons) into the most sensitive areas of a microSQUID sensor. The nearly optimum flux coupling between these nanomagnets and the microSQUID improves the achievable sensitivity by a factor 100, enabling us to measure the linear susceptibility of the molecular array down to very low temperatures (13 mK). This method opens the possibility of applying ac susceptibility experiments to characterize two-dimensional arrays of single molecule magnets within a wide range of temperatures and frequencies.Comment: 4 pages 3 figure

Dysregulation of the endocannabinoid signaling system in the cerebellum and brainstem in a transgenic mouse model of spinocerebellar ataxia type-3.

Spinocerebellar ataxia type-3 (SCA-3) is a rare disease but it is the most frequent type within the autosomal dominant inherited ataxias. The disease lacks an effective treatment to alleviate major symptoms and to modify disease progression. Our recent findings that endocannabinoid receptors and enzymes are significantly altered in the post-mortem cerebellum of patients affected by autosomal-dominant hereditary ataxias suggest that targeting the endocannabinoid signaling system may be a promising therapeutic option. Our goal was to investigate the status of the endocannabinoid signaling system in a transgenic mouse model of SCA-3, in the two CNS structures most affected in this disease cerebellum and brainstem. These animals exhibited progressive motor incoordination, imbalance, abnormal gait, muscle weakness, and dystonia, in parallel to reduced in vivo brain glucose metabolism, deterioration of specific neuron subsets located in the dentate nucleus and pontine nuclei, small changes in microglial morphology, and reduction in glial glutamate transporters. Concerning the endocannabinoid signaling, our data indicated no changes in CB2 receptors. By contrast, CB1 receptors increased in the Purkinje cell layer, in particular in terminals of basket cells, but they were reduced in the dentate nucleus. We also measured the levels of endocannabinoid lipids and found reductions in anandamide and oleoylethanolamide in the brainstem. These changes correlated with an increase in the FAAH enzyme in the brainstem, which also occurred in some cerebellar areas, whereas other endocannabinoid-related enzymes were not altered. Collectively, our results in SCA-3 mutant mice confirm a possible dysregulation in the endocannabinoid system in the most important brain structures affected in this type of ataxia, suggesting that a pharmacological manipulation addressed to correct these changes could be a promising option in SCA-3.This study has been supported by MICINN (SAF2009-11847 and SAF2015-68580-C2-1-R), CIBERNED (CB06/05/0089), "Fundacion Eugenio Rodriguez Pascual" and the Research and Education Component of the Advancing a Healthier Wisconsin Endowment at the Medical College of Wisconsin.

Detection of aluminium hydroxide-induced granulomas in sheep by computed tomography: A feasible approach for small ruminant lentiviruses diagnosis and research

Aluminium (Al) hydroxide use as adjuvant induces local formation of long-lasting subcutaneous granulomas in sheep. Macrophages within these granulomas have been identified as a new small ruminant lentivirus (SRLV) replication site in naturally infected animals. Diagnosis of Al hydroxide-induced granulomas in sheep is mostly based on postmortem observations but little information is available on in vivo detection. Computed tomography (CT) is used for studying these reactions in other animal species. To determine if CT could be a tool for in vivo diagnosis and research of subcutaneous Al hydroxide-induced granulomas in sheep. A retrospective survey on thoracic CT scans was performed on 46 adult sheep. Analysis included absence or presence, number and location of subcutaneous nodules. Thoracic CT scans and pathological studies were prescribed to two further sheep. Single or multiple subcutaneous nodules were detected in 26 (56.52%) sheep. One or two nodules per animal were most often observed (36.95%). Size ranged between 1.5 and 4.5 cm. Pre-contrast two-dimensional (2D) CT images showed focal or multifocal increases in subcutaneous tissue thickness. Post-contrast 2D CT images revealed hypointense areas in the centre. Histopathology indicated the presence of granulomas composed by a large number of activated macrophages, surrounding a central core of necrosis. Large intracytoplasmic Al-positive aggregates were demonstrated by lumogallion staining. CT is a useful tool to detect subcutaneous Al hydroxide-induced granulomas in vivo in sheep. CT provides a diagnostic and research tool that can be very useful in future works in Al hydroxide-induced pathology, SRLV infection, or both. © 2021 The Authors.
