Mallorca, the largest of the Balearic Islands, is a well-known summer holidays destination; an ideal place to relax and enjoy the sun and the sea. That tourist gaze reflected on postcards results from advertising campaigns, where cinema played an important role with documentaries and fiction films. The origins of that iconography started in the decades of the 1920’s and 1930’s, reflecting the so-called myth of the “island of calm”. On the other hand, the films of the 1950’s and 1960’s created new stereotypes related to the mass tourism boom. Busy beaches and the white bodies of tourists replaced white sandy beaches, mountains and landscapes shown up in the movies of the early decades of the 20th century. Besides, hotels and nightclubs also replaced monuments, rural landscapes and folk exhibitions. These tourist images mirror the social and spatial transformations of Mallorca, under standardization processes like other seaside mass tourist destinations. The identity was rebuilt on the foundations of "modernity". Although "balearization" has not ceased, nowadays filmmaking about Mallorca is advertising again a stereotype close to that one of the 1920s and 1930s, glorifying the myth of the "island of calm". This singular identity makes the island more profitable for capital that searches socio-spatial differentiation in post-fordist times.

El artículo analiza firmas insertas en circuitos globalizados de exportación de frutas frescas, así como la interfase empresas-territorios. Se focaliza en la producción argentina de cítricos dulces y particularmente en un espacio productivo, y se interesa por cómo se traduce la construcción de los circuitos globales en los espacios y actores locales. Para ello, desarrolla una tipología de empresas e indicadores de anclaje y recurre a una combinación de fuentes cuantitativas y cualitativas, con vistas a desentrañar la “caja negra” del comportamiento empresarial. Se concluye que existen diferentes grados de anclaje territorial y combinaciones variables de fijación y movilidad por parte de las empresas. La adopción de una modalidad de agricultura empresarial multilocalizada, orientada al aprovechamiento de las peculiaridades de los diferentes ambientes locales, conduce a la desarticulación de espacios en función de sus características productivas y de sus diversos contextos sociales e institucionales. De esta forma se promueve la conformación de agentes de características flexibles, transformando su reproducción en contingente.

Las épocas de crisis político-social propician en especial medida la creación y el afianzamiento de determinados auto y heteroestereotipos. Esta afirmación resulta concluyente cuando se analiza cómo las distintas fases políticas de España a lo largo de la historia han condicionado de manera definitiva su imagen en el extranjero, en especial en Alemania. Las imágenes y estereotipos románticos creados a partir de la Guerra de la Independencia (1808-1814) sirvieron durante la primera mitad del siglo veinte de instrumento de manipulación propagandística que debía contribuir a ensalzar la ejemplaridad del aliado español. Este artificio político, que buscaba la simpatía ideológica con el sistema de valores nacionalsocialista, se valió de manera particular de las producciones cinematográficas hispano-alemanas para lograr su objetivo.

Desde su nacimiento hasta la caída de la dictadura de Primo de Rivera, el ferrocarril se perfiló como una industria doblemente creadora de riqueza, estimulando por un lado la ya existente e impulsando el desarrollo económico por otro. Ante sus peculiaridades técnicas, económicas y de mercado, los distintos gobiernos adoptaron soluciones intervencionistas de mayor o menor grado. Simultáneamente, en su primer desarrollo, se produjo el abandono del paradigma clásico basado en la libre competencia, lo que derivó en la conversión del ferrocarril en foco de la retórica anti-competencia y de la práctica intervencionista. En este trabajo realizamos un seguimiento del nacimiento y desarrollo del ferrocarril, centrado exclusivamente en la evolución político-económica del sector dentro de la propia evolución histórica, paralela a la vía nacionalista del capitalismo español, y en la descriptiva teórica y práctica del desarrollo del intervencionismo y las restricciones al libre mercado.

El objetivo del trabajo es analizar los diferentes modelos de gestión que pueden presentar las sociedades cooperativas. Tras una descripción de los modelos monista y dualista, así como de las distintas variantes que puede presentar este último modelo, se analizan los factores determinantes de su elección. Los factores analizados son: el tamaño, la edad y la actividad de la cooperativa. El análisis empírico ha sido realizado a partir de una muestra de empresas cooperativas españolas. Los resultados obtenidos muestran que el modelo dualista se utiliza, fundamentalmente en empresas grandes, de mayor edad y cuya actividad es la industria o los servicios.

Introduction - Mycotoxin contamination was reported to occur in some food and commodities, such as coffee, particularly due to the presence of toxigenic fungi such as Aspergillus, Penicillium and Fusarium spp. Aspergilli are known to produce high levels of mycotoxins, such as ochratoxin and aflatoxin. Aspergillus ochraceus has been proposed as the major cause of ochratoxin A contamination in coffee beans. Aim of the study - The aim of this work was to evaluate the prevalence of Aspergillus sections Circumdati, Flavi and Fumigati in 28 green coffee samples to be used by Portuguese coffee industry, from Coffea arabica (Arabica coffee) and Coffea canephora (Robusta coffee) species from different origins.

Introduction - Occupational exposures are characterized by being complex and associated to co-exposure to several contaminants by different exposure routes. Even if exposure occurs to only a chemical agent, it can have different exposure routes and can result in different health effects. The waste management setting is recognized by the presence of several chemical and biologic agents in the workplaces. Recently, it was reported occupational exposure to Aflatoxin B1 (AFB1) in one Portuguese waste management industry. However, data regarding to fungal burden showed that exposure to other mycotoxins should be expected. Aim of the study - The aim of the present work was to know if workers from this waste management industry were exposed to other mycotoxins besides AFB1.

Occupational exposure assessment can be a challenge due to several factors being the most important the costs associate and the result's dependence from the conditions at the time of sampling. Conducting a task-based exposure assessment allow defining better control measures to eliminate or reduce exposure since more easily identifies the task with higher exposure. A research study was developed to show the importance of task-based exposure assessment in four different settings (bakery, horsemanship, waste sorting and cork industry). Measurements were performed using a portable direct-reading hand-held equipment and were conducted near the workers nose during tasks performance. For each task were done measurements of approximately 5 minutes. It was possible to detect the task in each setting that was responsible for higher particles exposure allowing the priority definition regarding investments in preventive and protection measures.

The Green Deal (GD) was launched in 2013 by the UK Government as a market-led scheme to encourage uptake of energy efficiency measures in the UK and create green sector jobs. The scheme closed in July 2015 after 30 months due to government concerns over low uptake and industry standards but additional factors potentially contributed to its failure such as poor scheme design and lack of understanding of the customer and supply chain journey. We explore the role of key delivery agents of GD services, specifically SMEs, and we use the LoCal-Net project as a case study to examine the use of networks to identify and reduce barriers to SME market engagement. We find that SMEs experienced multiple barriers to interaction with the GD such as lack of access to information, training, and confusion over delivery of the scheme but benefited from interaction with the network to access information, improve understanding of the scheme, increasing networking opportunities and forming new business models and partnerships to reduce risk. The importance of SMEs as delivery agents and their role in the design of market-led schemes such as the GD are discussed with recommendations for improving SME engagement in green sector initiatives.

The viscosity of biodiesels of soybean and rapeseed biodiesels blended with mineral diesel fuel were measured at pressures of up to 200 MPa. Using a falling sinker-type viscometer reproducible viscosity data were obtained based on the time taken for a sinker to descend a fixed distance down an enclosed tube under the influence of gravity. Measurements were taken using pressures which correspond to those of interest in automotive common rail diesel engines, and at temperatures of between 25oC and 80oC. In all cases, the viscosity of the biodiesel blends were found to increase exponentially for which the blends were noted as being more viscous than pure mineral fuels. A pressure-freezing effect was not observed for the blends.

For SMEs to operate in the complex and globalised economic landscape of today engaging with innovation can sustain competitive advantage. Within Design Management, design is being increasingly posited as a strategic resource to facilitate the absorption of new design resources and leverage design knowledge in ways that support SMEs through such economic pressures. Evidencing the relationship between design and economic performance is complex, leading to extensive current research and industry efforts to show how design adds economic value. Despite the value of such efforts, it is important to recognise that innovation means different things to different organizations, especially for start-ups and SMEs. Within the rising tide of design-led innovation, there is a gap being explored in how design can effectively capture and evaluate its contribution within the complex and diverse situations of business development it engages. In seeking to address this gap, this paper presents findings from research undertaken within Design in Action (DiA), an AHRC-funded knowledge exchange hub. Presenting DiA as a single case study, the paper offers methodical reflection on five case example start-up businesses funded by DiA in order to explore the value that design-led innovation approaches offered in their formation.

Esta monografía es el análisis financiero actual de la ebanistería JAR. Se propuso desde el principio conocer la situación real financiera de la ebanistería para dar una orientación a los dueños de la compañía, sobre que decisiones puedan tomar para mejorar los resultados de la empresa. Para llevar a cabo el análisis y el diagnóstico financiero de la ebanistería, se tomó como base los balances y estados financieros de los años 2011 hasta el 2014. Adicionalmente se recopilo información financiera de empresas del sector para compararlos con los resultados de la ebanistería JAR. En base a la información recopilada, se sacaron los indicadores de endeudamiento, liquidez, rentabilidad e inductores de valor. Toda esta información es analizó y cotejó para obtener las conclusiones y recomendaciones esperadas. La ebanistería JAR no se encuentra en una difícil situación financiera como los dueños de la ebanistería lo habían planteado en un comienzo. Más bien sus directivos están comparando épocas muy distintas de la historia de la ebanistería y de la historia económica de Colombia que los hace pensar que las cosas no están bien. Cuando se hace el análisis comparativo de los indicadores de rentabilidad de la ebanistería JAR contra las ebanisterías del sector, se encuentra que los indicadores de rentabilidad ROA y RONA, son incluso levemente superiores a los del sector para el año 2014.

Purpose The aim of this study was to test the effects of sprint interval training (SIT) on cardiorespiratory fitness and aerobic performance measures in young females. Methods Eight healthy, untrained females (age 21 ± 1 years; height 165 ± 5 cm; body mass 63 ± 6 kg) completed cycling peak oxygen uptake ( V˙O2V˙O2 peak), 10-km cycling time trial (TT) and critical power (CP) tests pre- and post-SIT. SIT protocol included 4 × 30-s “all-out” cycling efforts against 7 % body mass interspersed with 4 min of active recovery performed twice per week for 4 weeks (eight sessions in total). Results There was no significant difference in V˙O2V˙O2 peak following SIT compared to the control period (control period: 31.7 ± 3.0 ml kg−1 min−1; post-SIT: 30.9 ± 4.5 ml kg−1 min−1; p > 0.05), but SIT significantly improved time to exhaustion (TTE) (control period: 710 ± 101 s; post-SIT: 798 ± 127 s; p = 0.00), 10-km cycling TT (control period: 1055 ± 129 s; post-SIT: 997 ± 110 s; p = 0.004) and CP (control period: 1.8 ± 0.3 W kg−1; post-SIT: 2.3 ± 0.6 W kg−1; p = 0.01). Conclusions These results demonstrate that young untrained females are responsive to SIT as measured by TTE, 10-km cycling TT and CP tests. However, eight sessions of SIT over 4 weeks are not enough to provide sufficient training stimulus to increase V˙O2V˙O2 peak.

The negative effects of climate change are already evident for many of the 25 million coffee farmers across the tropics and the 90 billion dollar (US) coffee industry. The coffee berry borer (Hypothenemus hampei), the most important pest of coffee worldwide, has already benefited from the temperature rise in East Africa: increased damage to coffee crops and expansion in its distribution range have been reported. In order to anticipate threats and prioritize management actions for H. hampei we present here, maps on future distributions of H. hampei in coffee producing areas of East Africa. Using the CLIMEX model we relate present-day insect distributions to current climate and then project the fitted climatic envelopes under future scenarios A2A and B2B (for HADCM3 model). In both scenarios, the situation with H. hampei is forecasted to worsen in the current Coffea arabica producing areas of Ethiopia, the Ugandan part of the Lake Victoria and Mt. Elgon regions, Mt. Kenya and the Kenyan side of Mt. Elgon, and most of Rwanda and Burundi. The calculated hypothetical number of generations per year of H. hampei is predicted to increase in all C. arabica-producing areas from five to ten. These outcomes will have serious implications for C. arabica production and livelihoods in East Africa. We suggest that the best way to adapt to a rise of temperatures in coffee plantations could be via the introduction of shade trees in sun grown plantations. The aims of this study are to fill knowledge gaps existing in the coffee industry, and to draft an outline for the development of an adaptation strategy package for climate change on coffee production.
