Estudio sobre la situación de la vivienda pública en la Comunitat Valenciana

El objetivo de este estudio se sitúa, en primer lugar, en la identificación de la situación en la que se halla la vivienda pública en la Comunitat Valenciana, entendiendo por tal la vivienda que se encuentra gestionada por las administraciones públicas con competencias en la materia; y ello desde un doble punto de vista: tanto la situación de la oferta de vivienda pública, como el estado de la demanda de la misma. Se observa la vivienda pública como un instrumento más de la política social destinada a proteger a los sectores más desfavorecidos, por lo que se evalúa la demanda actual de vivienda pública, se estiman los niveles de demanda potencial de vivienda pública en caso de deterioro o colapso económico, con la finalidad de programar y ejecutar unos instrumentos de intervención y, en especial, un parque público de vivienda acorde a las necesidades de una vivienda, especialmente en los casos de extrema necesidad. El objetivo final del estudio es la comparación de las variables estudiadas (oferta y demanda) y la obtención de conclusiones útiles para el diseño, por parte de las administraciones competentes, de una política social de vivienda. El trabajo busca identificar las cuestiones transcendentales para la política social de vivienda, como es saber cuántos son los demandantes actuales y futuros de vivienda, qué tipología y necesidades en vivienda presentan, dónde se ubican y, por lo tanto, dónde se debe construir las viviendas sociales destinadas a satisfacer sus necesidades, cuál es el nivel exacto de pobreza en vivienda y pobreza asociada a la vivienda de los hogares valencianos, entre otras cuestiones relacionadas con este mercado, como son la identificación de los ciclos de edificación históricos, de las series de precios, la evaluación de la distribución de la renta a nivel provincial y en áreas locales, y la estimación de la pobreza energética asociada a los hogares en la Comunidad Valenciana

Natural Hosts and Genetic Diversity of the Emerging Tomato Leaf Curl New Delhi Virus in Spain

Knowledge about the host range and genetic structure of emerging plant viruses provides insights into fundamental ecological and evolutionary processes, and from an applied perspective, facilitates the design and implementation of sustainable disease control measures. Tomato leaf curl New Delhi virus (ToLCNDV) is an emerging whitefly transmitted begomovirus that is rapidly spreading and inciting economically important diseases in cucurbit crops of the Mediterranean basin. Genetic characterization of the ToLCNDV Mediterranean populations has shown that they are monophyletic in cucurbit plants. However, the extent to which other alternative (cultivated and wild) hosts may affect ToLCNDV genetic population structure and virus prevalence remains unknown. In this study a total of 683 samples from 13 cultivated species, and 203 samples from 24 wild species from three major cucurbit-producing areas of Spain (Murcia, Alicante and Castilla-La Mancha) from five cropping seasons (2012–2016) were analyzed for ToLCNDV infection. Except for watermelon, ToLCNDV was detected in all cultivated cucurbit species as well as in tomato. Among weeds, Ecballium elaterium, Datura stramonium, Sonchus oleraceus, and Solanum nigrum were identified as alternative ToLCNDV plant hosts, which could act as new potential sources of virus inoculum. Furthermore, we performed full-genome deep-sequencing of 80 ToLCNDV isolates from different hosts, location and cropping year. Our phylogenetic analysis supports a Mediterranean virus population that is genetically very homogeneous, with no clustering pattern, and clearly different from Asian virus populations. Additionally, D. stramonium displayed higher levels of within-host genetic diversity than cultivated plants, and this variability appeared to increase with time. These results suggest that the potential ToLCNDV adaptive evolution occurring in wild plant hosts could serve as a source of virus genetic variability, thereby affecting the genetic structure and spatial-temporal dynamics of the viral population

Pregnancy Success in Bitches - Evaluation of Interactions between Artificial Insemination Method, Serum Progesterone Concentration and Vaginal Cytology Parameters

Background: The artificial insemination has become a well-established method in the breeding of bitches, and evaluation of the factors that may potentially affect pregnancy success is essential. For this reason, it is essential to evaluate the factors that may affect fertility of the bitch when artificial insemination is performed. Serum progesterone concentrations and vaginal cytology have been used to determine the time of ovulation and stage of the estrus cycle. This study aimed to evaluate the artificial insemination method, the serum progesterone concentration, the breed size, age, the whelping number, vaginal cytology parameters, and their interactions on pregnancy success in bitches. Materials, Methods & Results: A total of 607 bitches that had undergone reproductive consultation with the Mexican Canine Federation from January to December 2016 were enrolled in the present study and assigned to one of 2 artificial insemination methods (intravaginal and transcervical) using fresh semen. Determination of the estrus cycle phase and the time of Artificial insemination was based on vaginal cytology and serum progesterone concentrations. Bitches inseminated by the transcervical technique had a higher pregnancy rate with respect to females inseminated by the intravaginal technique (P < 0.05). Moreover, females with a serum progesterone concentration of 5-10 ng/mL had a greater probability (> 4 times) of getting pregnant than animals with lower or higher progesterone concentrations (P < 0.05). Bitches inseminated by the intravaginal technique and with serum progesterone concentrations >10 ng/mL had a considerable reduction in pregnancy (P < 0.05) compared with females with < 10 ng/mL serum progesterone or with bitches inseminated by the transcervical technique. Discusion: Serum progesterone concentration, the artificial insemination method, and superficial cells without a nucleus modified the pregnancy rate in bitches. Females inseminated by transcervical semen deposition had a higher pregnancy rate than females inseminated by the intravaginal technique. Using fresh or frozen-thawed semen produced a higher pregnancy rate in bitches inseminated by transcervical semen deposition than females inseminated by the intravaginal technique. Differences in the pregnancy rate between transcervical and intravaginal insemination could be associated with the correct semen disposition, the distance that the sperm must travel to reach the oocyte, as well as the number of sperm that reach the oviduct ampulla. Exist evidences that after ovulation, as progesterone rises, the cervix is closed, which may compromise the passage of the sperm deposited into the vagina. Therefore, it is likely that in females with a serum progesterone concentration > 10 ng/mL, the cervix was closed, compromising the ability of the sperm to access the oviduct. Thus, the use of intravaginal insemination should be done in bitches with a serum progesterone concentrations < 11 ng/mL to reduce the possibility of cervical closure and to increase the odds of pregnancy. It is well documented that the serum progesterone concentration and vaginal cytology parameters have a great influence on pregnancy success, and the results confirm these findings. In the present study, 96% of the bitches inseminated with a serum progesterone concentration of 5-10 ng/mL got pregnant and had higher odds of pregnancy than bitches with lower or higher serum progesterone concentrations.

Pot-Pollen and Pot-Honey from Stingless Bees of the Alto Balsas, Michoacán, Mexico: Botanical and Physicochemical Characteristics

The demand for stingless bees’ products (pot-honey and pot-pollen) has increased. No formal quality standards have been defined, which is very complex, because of the variety of species and types of honey specific to each region. For this reason, it is important to deepen the understanding of stingless bees’ honey characteristics. From the above, the aim of this chapter is to present the advances in the characterization of botanical origin of stingless bees’ honey, and the analysis of their physicochemical properties in the Alto Balsas, Michoacán, Mexico, as a way to contribute to the strengthening of new local economic strategies, generating information on the quality of the honey produced in the region

Realidad Aumentada Educativa: una propuesta desde las perspectivas y enfoques.

Experimental works about Augmented Reality (AR) among educational characteristics (Kaufmann H, 2009), express that their applications act as a method with benefits in the learning process; motivating creativeness and the construction of mental innovative models regarding engineering topics (Kesim, Ozarslan, 2012)(Di Serio, Á., Ibáñez, M. B., & Kloos, C. D., 2013), from schooling at the kinder garden stage, high schools and universities, to science centres (Novak-Marcincin J., Barna J., Janak M. & Novakova-Marcincinova L., 2013) where AR has been used as a innovational technology; Other reports alined with the TIC expose the AR as an emergent technology about to be implemented on the following years (Johnson L., Smith R., Willis H., Levine A., & Haywood K., 2011); according the projects and their reports it’s been identified the existence of various methodologies, designs and approaches for the utilization of AR in the educational field: the instructional design, the characteristics and affordances and the pedagogical intention are defined for each application where the instructor proposes an unique style for its construction, yet the teacher has to be supported for the programming and creation of those apps using AR. The revision and analysis of different works allows the sustainability of the need of giving the docent a system where the authorship for the generation of AR, where the content, design and application will be part of the profesor’s self-management, allowing its modification and updating. Trabajos experimentales sobre Realidad Aumentada (RA) con características educativas (Kaufmann H, 2009), expresan que sus aplicaciones actúan de manera positiva en el aprendizaje, motivación creatividad o inclusive, construyendo modelos mentales innovadores sobre cuestiones de ingeniería (Kesim, Ozarslan, 2012)(Di Serio, Á., Ibáñez, M. B., & Kloos, C. D., 2013)

Predictors of the Quality of Life of University Students: A Cross-Sectional Study

Quality of life (QOL) is a complex and multifaceted concept that has been used to study different aspects of people’s lives, including physical and psychological wellbeing, financial independence, social relationships, personal beliefs and living situation. In this study, we aimed to assess the QOL of a group of Spanish university students and identify associated factors. Method: We completed a cross-sectional study of the QOL of 868 university students using the WHOQOL-BREF questionnaire. In addition, data regarding sociodemographic information and self-esteem (Rosenberg Self-Esteem Scale), physical activity (International Physical Activity Questionnaire—Short version), diet (Spanish Index of Healthy Eating), alcohol consumption (CAGE questionnaire) and sleep quality (Pittsburgh Sleep Quality Index) were collected. Results: A total of 66.2% of participants assessed their QOL positively, while 58.8% favorably evaluated their overall health. Students reported the highest scores for the physical health domain of QOL, whereas they gave the lowest scores for the psychological health domain. Age was inversely associated with QOL. Higher self-esteem and satisfaction with academic performance, as well as sleep and diet quality, were directly associated with higher QOL. The physical health domain of QOL was scored more highly by participants who had a healthy body weight or those who reported moderate levels of physical activity. Higher scores in the social relationships domain of QOL were directly linked to alcohol intake, smoking and low body weight in addition to being inversely associated with screen time. The psychological domain of QOL was lower for those who were overweight or lived alone. Conclusion: Many sociodemographic, academic and behavioral variables are associated with university students’ QOL. The present findings underscore the need to direct further initiatives toward identifying and overcoming barriers to increased QOL for university students
