La gestión de las emociones en la docencia universitaria

En el ámbito de la Psicología existe amplio consenso acerca de la estrecha relación entre emoción y motivación. A su vez, la motivación del estudiante ejerce una influencia positiva sobre los resultados de la actividad académica. Sin embargo, hasta la fecha se ha prestado escasa atención al rol de las emociones en el proceso de enseñanza-aprendizaje. Más concretamente, cabría plantearse si las emociones pueden interferir en el recuerdo y, por ende, en la valoración de las actividades realizadas en el curso. Por ello, asumiendo las hipótesis derivadas del modelo de red asociativa de la emoción, que predice que el estado de ánimo tiende a producir un efecto de recuerdo congruente con dicho estado de ánimo, el objetivo del presente trabajo es examinar la posible interferencia de las emociones en la valoración de las actividades realizadas en una asignatura del Grado de Turismo. Como resultado se obtiene, en general, la ausencia de efecto de recuerdo congruente con el estado de ánimo. De ello se derivan una serie de conclusiones acerca de la gestión de las emociones en el aula y de la creación de entornos que favorezcan la implicación emocional del estudiante y, con ello, su motivación por la asignatura

ICT: an empowering tool for social enterprises

In recent years new models for organizations working on poverty alleviation have emerged. One of them, the social enterprise, has attracted the attention of both academics and practitioners all over the world. Even if defined in different ways depending on the context, this model has an enormous potential to generate social benefits and to promote local agency and private initiative in poverty alleviation

Influence of a Novel Surface of Bioactive Implants on Osseointegration: A Comparative and Histomorfometric Correlation and Implant Stability Study in Minipigs

Purpose: The objective of this study was to assess the influence of a novel surface of dental implants (ContacTi®) on the osseointegration process in a minipig model. The surface was compared with other existing surfaces on the market (SLA® and SLActive®) by employing bone implant contact analysis (BIC) and implant stability. Method: Twelve minipigs were used with prior authorisation from an ethics committee. Three types of surfaces were tested: SLA® (sand-blasted acid-etched titanium), SLActive® (same but hydrophilic, performed under a nitrogen atmosphere), and ContacTi® (alumina particle bombardment of titanium, bioactivated when treated thermochemically) in 4.1 mm × 8 mm implants with internal connection and a polished neck. Twelve implants of each surface type (N = 36) were placed, sacrificing 1/3 of the animals at 2 weeks of placement, 1/3 at 4 weeks and the remaining 1/3 at 8 weeks. Numerical variables were compared with Analysis of Variance, and the correlation between ISQ and BIC was established with the Spearman’s rank correlation coefficient. Results: SLActive® and ContacTi® surfaces showed elevated osteoconductivity at 4 weeks, maintaining a similar evolution at 8 weeks (large amount of mature lamellar tissue with high maturity and bone quality). The SLA® surface showed slower maturation. The ISQ values in surgery were elevated (above 65), higher at necropsy and higher at 4 and 8 weeks in the SLA® group than in the other two (SLActive® and ContacTi®). No significant correlation was found between ISQ and BIC for each implant surface and necropsy time. Conclusion: The three surfaces analysed showed high RFA and BIC values, which were more favourable for the SLActive® and ContacTi® surfaces. No statistical correlation was found between the RFA and BIC values in any of the three surfaces analysed.Research Foundation of the University of Seville Project Code 187

Alveolitis seca: actualización de conceptos

La alveolitis seca es una complicación postoperatoria que acontece tras la extracción dental, quedando definida como una inflamación del alveolo. En el caso que esta inflamación sobrepase las paredes alveolares, estaríamos ante una osteítis localizada. La frecuencia de aparición de la alveolitis se ha referido en un margen muy amplio, desde el 1 % hasta el 70 %. Generalmente se acepta que la mayor incidencia de alveolitis acontece tras la extracción de terceros molares retenidos, en los que la aparición de esta complicación se tasa en un 20-30 % de las extracciones, diez veces más que en el resto de extracciones dentales. En el presente artículo se revisan la forma de aparición clínica, los factores de riesgo relacionados con el cuadro y las teorías etiopatogénicas que intentan explicar su aparición. También se examinan las pautas utilizadas actualmente en su tratamiento. Acorde con las teorías patogénicas de la alveolitis seca, para su prevención se han estudiado agentes fibrinolíticos, lavados, antisépticos y antibióticos. Analizamos los distintos fármacos utilizados, criticando los resultados obtenidos. Como conclusión, y a partir de los datos revisados, pensamos, sin abandonar el territorio de la hipótesis, que es posible defender un modelo patogénico en el que los mecanismos fibrinolíticos bacterianos y del propio organismo colaboren para producir la alveolitis seca.Dry socket is a postoperative complication that occurs after a dental extraction and has been defined as an inflammation of the alveolus. If this inflammation should surpass the alveolar walls, it would result in a located osteitis. The frequency of appearance of dry socket has been reported in a very wide margin, from 1% until 70%. It is generally accepted that most dry sockets appear after extraction of third retained molars, in which the occurrence of this complication is about 20-30% of dental extractions, ten times more than in the rest of dental extractions. In this work we review the forms of clinical appearance, the risk factors related to this affection and the etiopathogenic theories that try to explain its appearance. The treatment management is also examined. Fibrinolitic agents, laundries, antiseptic, and antibiotics have been studied for its prevention, according to the pathogenic theories of dry socket. We analyze and critize the different drugs and their results. In conclusion from the revised data, we think it is possible to defend a pathogenic model in which the bacterial fibrinolytic mechanisms and the microorganism of the own patient may contribute to produce the dry socket

Seasonal Analysis Comparison of Three Air-Cooling Systems in Terms of Thermal Comfort, Air Quality and Energy Consumption for School Buildings in Mediterranean Climates

Efficient air-cooling systems for hot climatic conditions, such as Southern Europe, are required in the context of nearly Zero Energy Buildings, nZEB. Innovative air-cooling systems such as regenerative indirect evaporative coolers, RIEC and desiccant regenerative indirect evaporative coolers, DRIEC, can be considered an interesting alternative to direct expansion air-cooling systems, DX. The main aim of the present work was to evaluate the seasonal performance of three air-cooling systems in terms of air quality, thermal comfort and energy consumption in a standard classroom. Several annual energy simulations were carried out to evaluate these indexes for four different climate zones in the Mediterranean area. The simulations were carried out with empirically validated models. The results showed that DRIEC and DX improved by 29.8% and 14.6% over RIEC regarding thermal comfort, for the warmest climatic conditions, Lampedusa and Seville. However, DX showed an energy consumption three and four times higher than DRIEC for these climatic conditions, respectively. RIEC provided the highest percentage of hours with favorable indoor air quality for all climate zones, between 46.3% and 67.5%. Therefore, the air-cooling systems DRIEC and RIEC have a significant potential to reduce energy consumption, achieving the user’s thermal comfort and improving indoor air quality

The Role of ICT in Scaling Up the Impact of Social Enterprises

Information and Communication Technologies (ICT) can help social enterprises and other organizations working on global sustainability issues and in the human development sector in general scale their social impact. The flexibility, dynamism, and ubiquity of ICTs make them powerful tools for improving relationships among organizations and their beneficiaries, multiplying the effects of action against many, if not all, aspects of global unsustainability, including poverty and exclusion. The scaling of social impact occurs in two different dimensions. On one hand, ICTs can increase the value proposition of a program or action (depth scaling) in different ways: providing accurate and fast needs recognition, adapting products and services, creating opportunities, building fairer markets, mobilizing actions on environmental and social issues, and creating social capital. On the other hand, ICTs can also increase the number of people reached by the organization (breadth scaling) by accessing new resources, creating synergies and networks, improving organizational efficiency, increasing its visibility, and designing new access channels to beneficiaries. This article analyzes the role of ICT in the depth and breadth scaling of social impact

Flapless implant surgery: a review of the literature and 3 case reports

Since the 1970s, modern Implantology is based on a concept of surgery with flap elevation. Gradually, several clinical trials demonstrated that a mid-crestal incision gives similar success rates compared to those obtained using the classical protocol. However, over the past decade in medicine it has been established the concept of minimally invasive surgery, consisting in taking advantage of advancements experienced in diagnostic techniques and specific surgical instruments, to perform surgical procedures infringing as less damage as possible to the patient The present work aims to produce a thorough review of the literature published on the field of Implantology with flapless surgery, to determine the current scientific evidence of the technique, along with illustrating the results with different clinical cases. After presenting the clinical cases, and the review of literature, we can say that flapless surgeries should be restricted to well-selected cases in which a proper clinical and radiological planning has been made. Patients treated with anticoagulant drugs or medically compromised equally can get benefitted by this minimal invasion technique

Proposal for a preventive protocol for medication-related osteonecrosis of the jaw

Medication-related osteonecrosis of the jaw (MRONJ) is a severe adverse reaction experienced by some patients exposed to certain drugs (antiresorptives such as bisphosphonates or denosumab, and antiangiogenic drugs). From a review of the literature it appears that there is no uniform criterion when selecting preventive measures; these vary according to author. Likewise, the measures recommended are usually general, so that in few cases they result in specific actions to be applied depending on the different variables involved such as the type of drug used, the duration of its application, the underlying pathology, the presence or absence of risk factors, etc. The aim of this study has been to design a preventive protocol which can be easily applied in any clinic or by any dental care service. We undertook an exhaustive literature review to find any articles related to the topic of study, namely, preventive measures for medication-related osteonecrosis of the jaw, on the one hand generically and on the other focusing on dental implant treatment. The most part the criteria of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. From 3946 items, we selected a total of 21 items. From the analysis of the selected articles, several protocols have been developed that are easy to apply in a dental clinic.: Protocol 1. Before starting treatment with antiresorptives (Patients who are going to be treated for osteoporosis / Patients who are going to be treated for cancer). Protocol 2. Once treatment is initiated with antiresorptives (Patients being treated for osteoporosis / Patients being treated for cancer). The application of these protocols requires an interdisciplinary team which can handle the various treatments and apply the measures contained in them. Along with a team of well-educated and trained dentists, it is equally important to maintain contact with the medical team involved in the treatment of the underlying pathology, especially rheumatologists, oncologists, internists and gynaecologists. All the above requires a great staff learning and organization effort, continuous training and coordination of the whole team involved in the preventive management of these patients

Impact of a Comprehensive Anti-Smoking Program at a Regional University Hospital and Predictive Variables of Being a Smoker among Hospital Workers

The objective of this study was to evaluate the impact of a comprehensive anti-smoking health program conducted over twelve years at a regional university hospital in southern Spain. Prevalence of tobacco was compared retrospectively using data collected during occupational health assessments (n = 4291). Bivariate and logistic regression analyses were carried out to evaluate tobacco consumption differences according to age, sex, professional category, and workplace building. The results show a reduction in the active smoking rate among hospital staff evaluated (from 22.8% to 19.8%) with significant differences between non-health and health workers. Accumulated smoking consumption fell to 13.45 ± 14.60 packs/year with men presenting a higher consumption (p < 0.001). The predictive variables of tobacco use were sex (greater consumption among men, p = 0.021), number of cigarettes (greater consumption among professionals who smoked less than 1 pack/day, p < 0.001), and time smoking (greater use among professionals with more than 10 years smoking, p < 0.001). There was a higher rate of staff smokers at the hospital building with a majority of mental health inpatients. This study provides a practical example of making the optimum use of digital medical records in the evaluation of a comprehensive anti-smoking health program
