Models for damped water waves

In this paper we derive some new weakly nonlinear asymptotic models describing viscous waves in deep water with or without surface tension effects. These asymptotic models take into account several different dissipative effects and are obtained from the free bound- ary problems formulated in the works of Dias, Dyachenko and Zakharov (Physics Letters A, 2008 ), Jiang, Ting, Perlin and Schultz (Journal of Fluid Mechanics,1996 ) and Wu, Liu and Yue (Journal of Fluid Mechanics, 2006 )

Local solvability and turning for the inhomogeneous Muskat problem

In this work we study the evolution of the free boundary between two different fluids in a porous medium where the permeability is a two dimensional step function. The medium can fill the whole plane R^2 or a bounded strip S=RX(-pi/2,pi/2). The system is in the stable regime if the denser fluid is below the lighter one. First, we show local existence in Sobolev spaces by means of energy method when the system is in the stable regime. Then we prove the existence of curves such that they start in the stable regime and in finite time they reach the unstable one. This change of regime (turning) was first proven in [5] for the homogenous Muskat problem with infinite depth

PROGRESSION OF CONTENTS AND OBJETIVES TO TEACH IN OBLIGATORY SECONDARY EDUCATION IN THE CONTENT UNIT OF ACTIVITIES IN THE NATURAL ENVIRONMENT

Las actividades en el medio natural tienen un papel principal en el ámbito educativo actual en base al cumplimiento de lo establecido en la Ley Orgánica 2/2006 de Educación y el Real Decreto 1631/2006 por el que se establecen las enseñanzas mínimas correspondientes a la Educación Secundaria Obligatoria (ESO). En estos documentos se establece que las actividades en el medio natural son uno de los cuatro bloques de contenidos a trabajar dentro de la Educación Física en el ámbito escolar. También se establecen los contenidos de la materia y de este bloque de contenidos. Por todo esto, el objetivo del presente trabajo es llevar a cabo una secuenciación justificada desde el punto de vista teórico de unidades didácticas recogiendo los contenidos que se pueden llevar a cabo en la ESO según la legislación vigente dentro del bloque de contenidos de actividades en el medio natural. Se proponen dos unidades didácticas en 1o ESO, tres en 2o y 3o ESO y una en 4o ESO, especificándose los contenidos de entre los recogidos en la legislación vigente que se va a trabajar en cada una de las unidades didácticas. En conclusión, debido a que las actividades en el medio natural ayudan a la adquisición de dos competencias básicas como son el conocimiento y la interacción con el mundo físico y la competencia social y ciudadana, las actividades en la naturaleza deben cobrar una mayor importancia en el ámbito escolar. Este trabajo es una propuesta de cómo hacerlo.At present the activities in the natural environment have a principal rol in the education environment, based on compliance with the provisions of Law 2/2006 of Education and the Royal Decree 1631/2006 wich lays down the mínimum core curriculum to the Obligatory Secondary Education (OSE). These documents established that the activities in the natural environment is one of the four content unit to teach in Physical Education in the school enviroment. It also establishes the contents of the subject and of this content unit. For all this, the aim of this papper is to perform a justified sequenzation from the theoretical point of view of didactic units, collecting the contents that can be carried out at OSE accordance with current legislation in the content unit of activities in the natural enviroment. It is proposed two didactic units in 1o OSE, three in 2o and 3o OSE and one in the 4o OSE, specifying the contents from those contained in the legislation to be teaching in each the didactic units. In conclusion, because the activities in the natural environment support the purchase of two basic competencies such as knowledge and interaction with the physical world and social competence and civic activities in nature should be a major way in the school environment. This paper is a proposal for how to do it.Actividad Física y Deport

Promoting dignified end-of-life care in the emergency department: a qualitative study

Background: Preservation of a dying person’s dignity in the emergency department (ED) is fundamental for the patient, his/her relatives and healthcare professionals. The aim of this study was to explore and interpret physicians’ and nurses’ experiences regarding conservation of dignity in end-of-life care in dying patients in the ED. Methods: A qualitative study based on the hermeneutic phenomenological approach, was carried out in the emergency department of two general hospitals. A total of 16 nurses and 10 physicians participated in the study. Data collection included 12 individual in-depth interviews and 2 focus groups. Results: The findings revealed that two themes represent the practices and proposals for the conservation of dignity in the emergency department: dignified care in hostile surroundings and the design of a system focused on the person’s dignity. Conclusion: Dignifying treatment, redesigning environmental conditions, and reorienting the healthcare system can contribute to maintaining dignity in end-of-life care in the ED

Predictor factors of perceived health in family caregivers of people diagnosed with mild or moderate Alzheimer's disease

Caring for a person diagnosed with Alzheimer’s disease has a negative impact on family caregivers’ psychological health. This study examined the factors related to ‘perceived health’ and ‘presence of new-onset mental health problems’ in family caregivers of people diagnosed with mild and moderate Alzheimer’s disease. A cross-sectional observational study carried out in Almeria’s Healthcare District (Spain). A total of 255 family caregivers (42.4% cared for people with mild Alzheimer’s disease and 57.6% cared for people with moderate Alzheimer’s disease) participated in the study from January to December 2015. Mainly, caregivers were women (81.5% in the mild Alzheimer’s disease group and 88.4% in the moderate Alzheimer’s disease group), and their average age was 56.54 years (standard deviation (SD) = 13.13) and 54.47 years (SD = 11.71), respectively. Around 47% of the caregivers had been caring for the person with Alzheimer’s between two and five years. The Goldberg General Health Questionnaire was used to measure perceived health and the presence of new-onset mental health problems. An exploratory descriptive analysis and a multivariate logistic regression analysis were conducted. For caregivers of people with mild Alzheimer’s disease, ‘perceived health’ was related to ‘perceived social support’ (r = −0.21; p = 0.028), ‘person’s level of dependency’ (r = −0.24, p = 0.05), ‘severity of the person’s neuropsychiatric symptoms’ (r = 0.22; p = 0.05), and ‘caregiver’s emotional distress in response to the person’s neuropsychiatric symptoms’ (r = 0.22; p = 0.05). For caregivers of people with moderate Alzheimer’s disease, ‘perceived health’ was related to ‘perceived social support’ (r = −0.31; p ˂ 0.01), ‘presence of neuropsychiatric symptoms’ (r = 0.27, p = 0.01), ‘severity of the person’s neuropsychiatric symptoms’ (r = 0.32, p = 0.01) and ‘caregiver’s emotional distress in response to the person’s neuropsychiatric symptoms’ (r = 0.029; p = 0.01). The presence of new-onset mental health problems was detected in 46.3% (n = 50) of caregivers of people with mild Alzheimer’s and 61.9% (n = 91) of caregivers of people with moderate Alzheimer’s. When people are diagnosed with mild Alzheimer’s disease, intervention programs for caregivers should aim to regulate emotions and promote positive coping strategies. When people are diagnosed with moderate Alzheimer’s disease, intervention programs for caregivers must allow them to adapt to caregiving demands that arise with the progression of Alzheimer’s disease

Business Process Re-engineering in Public Administration: The case study of Western Ligurian Sea Port Authority

Business Process Re-engineering (BPR) is a technique based on a radical redesign of the structure of an organization to improve its efficiency by optimizing processes and reducing costs. It has been proven effective over a plethora of private applications however, not many studies based on the public sector have been reported even though it is known to be inefficient. This is mainly due to an overall smaller market exposure of public administrations compared to private companies. However, nowadays, in the age of digitalization, the growing global competition is requiring PA to improve the efficiency of their processes. This paper offers a real case-study of an application of BPR in a PA namely the Genoa Port in Italy, one of the biggest ports in Europe. The following analysis has been carried out through an AS IS / TO BE approach and the outcome of the re-engineering process has been validated through Discrete Event Simulation. The results show how BPR can improve the efficiency of PAs and, particularly, how the port environment can drastically turn into an efficient and optimized system

Food addiction and lifetime alcohol and illicit drugs use in specific eating disorders

Background and aims: Food addiction (FA) and substance use (SU) have frequently been reported in patients with eating disorders (EDs). Our study aimed to assess the prevalence rates of FA and/or lifetime problematic alcohol and illicit drug use among patients with specific ED, such as: bulimia nervosa (BN), binge eating disorder (BED), and other specified feeding and eating disorder (OSFED). We sought to identify clinical, psychopathological, and personality profiles involved in these addictive behavior-based phenotypes. Methods: The total sample was 527 patients (176 BN, 115 BED, and 236 OSFED). FA was assessed through the Yale Food Addiction Scale 2.0. To determine lifetime SU, a semi structured clinical interview was carried out. Results: Patients with BN had the highest rates of FA both with and without SU. No gender differences were obtained for the prevalence of current FA and/or lifetime SU. Patients reporting at least one addictive-related behavior exhibited increased clinical severity compared to those who reported none. Increased impulsivity (such as high lack of premeditation, sensation seeking, and positive urgency) and low self-directedness were differentiating factors for presenting one or two addictive behaviors. Discussion and Conclusions: Overall, patients presenting with at least one addictive-like behavior reported a poorer clinical status than those without. Also, patients with FA and SU exhibited a more dysfunctional profile characterized by high impulsivity and low selfdirectedness. These findings would support the need for targeted treatments to reduce impulsivity and increase self-directedness, especially in patients with any addictive-related behavior, as a step towards improving their treatment outcome

Are Neurotrophin Genes Involved in the Pathophysiology of Gambling Disorder?

AmrZ is a major determinant of c-di-GMP levels in Pseudomonas fluorescens F113

The transcriptional regulator AmrZ is a global regulatory protein conserved within the pseudomonads. AmrZ can act both as a positive and a negative regulator of gene expression, controlling many genes implicated in environmental adaption. Regulated traits include motility, iron homeostasis, exopolysaccharides production and the ability to form biofilms. In Pseudomonas fluorescens F113, an amrZ mutant presents a pleiotropic phenotype, showing increased swimming motility, decreased biofilm formation and very limited ability for competitive colonization of rhizosphere, its natural habitat. It also shows different colony morphology and binding of the dye Congo Red. The amrZ mutant presents severely reduced levels of the messenger molecule cyclic-di-GMP (c-di-GMP), which is consistent with the motility and biofilm formation phenotypes. Most of the genes encoding proteins with diguanylate cyclase (DGCs) or phosphodiesterase (PDEs) domains, implicated in c-di-GMP turnover in this bacterium, appear to be regulated by AmrZ. Phenotypic analysis of eight mutants in genes shown to be directly regulated by AmrZ and encoding c-di-GMP related enzymes, showed that seven of them were altered in motility and/or biofilm formation. The results presented here show that in P. fluorescens, AmrZ determines c-di-GMP levels through the regulation of a complex network of genes encoding DGCs and PDEs

La necesidad de medir la motivación situacional en el contexto español de la educación física: Psicometría de la Situational Motivation Scale

El objetivo primario de este trabajo fue comparar la estructura factorial de las diversas versiones propuestas (SIMS-16, SIMS-15, SIMS-14 y SIMS-13), así como de explorar la posible sostenibilidad de una nueva estructura para la Situational Motivation Scale (SIMS) en el contexto español de la Educación Física. El objetivo secundario fue aportar evidencias que respalden la invariancia factorial, consistencia interna y validez externa de la mejor estructura factorial identificada. Participaron 644 estudiantes (344 hombres y 300 mujeres; Medad = 15,04, DT = 1,58) de educación secundaria obligatoria y bachillerato en clase de EF. El análisis factorial confirmatorio no respaldó psicométricamente las diferentes versiones (SIMS-16, SIMS-15, SIMS-14 y SIMS-13) identificadas por la investigación previa para la SIMS. No obstante, los hallazgos sustentaron psicométricamente un modelo factorial de cuatro factores correlacionados y 12 ítems, que permaneció invariante respecto al género y nivel educativo. El análisis correlacional apoyó la validez discriminante del instrumento y, a su vez, respaldó el continuum de auto-determinación. El análisis de consistencia interna reflejó adecuados valores para cada factor. Los resultados del modelo de ecuaciones estructurales respaldaron los asertos del Modelo Jerárquico de Motivación Intrínseca/ Extrínseca. Como conclusión, se recomienda la utilización de una nueva estructura factorial para la Situational Motivation Scale (modelo de cuatro factores correlacionados y 12 ítems) para el alumnado de EF de secundaria obligatoria y bachillerato en el contexto español
