Improving integrability via absolute summability: a general version of Diestel s Theorem

[EN] A classical result by J. Diestel establishes that the composition of a summing operator with a (strongly measurable) Pettis integrable function gives a Bochner integrable function. In this paper we show that a much more general result is possible regarding the improvement of the integrability of vector valued functions by the summability of the operator. After proving a general result, we center our attention in the particular case given by the -absolutely continuous operators, that allows to prove a lot of special results on integration improvement for selected cases of classical Banach spaces-including C(K), and Hilbert spaces-and operators-p-summing, (q, p)-summing and p-approximable operators.D.

Grado de interiorización de los sistemas de gestión medioambiental: una revisión de la literatura

El objetivo de este trabajo es analizar las principales características de los trabajos sobre interiorización de las normas de gestión medioambiental que fueron identificados a partir de una búsqueda electrónica en las bases de datos Web of Science, Science Direct, ProQuest y Emerald. Estos trabajos muestran que las empresas pueden tener un mayor o menor compromiso con los requisitos de una norma de gestión medioambiental, lo que puede llevar a niveles heterogéneos de interiorización e implantación. Además, los resultados de estos trabajos muestran que una mayor interiorización conlleva un mejor rendimiento medioambiental.The purpose of this paper is to analyze the main characteristics of studies that examine the internalization of environmental management standards. These studies were identified through an electronic search in Web of Science, Science Direct, Proquest and Emerald. These works show that firms may have a higher or lesser commitment with the requirements of an environmental management standard, and this issue may suppose different levels of internalization and implementation. Moreover, the findings of these studies show that a higher internalization leads to a better environmental performance

Internalization of Quality Management Standards: A Literature Review

This work examines the literature on the internalization of quality management standards via database searches (Web of Science, Emerald, ScienceDirect, and ABI/Inform-ProQuest). This review describes the characteristics of the relevant literature (theoretical or empirical, countries of study, and methods used), the internalization process (two constructs to measure internalization and items under each construct), drivers (reasons for seeking certification, quality culture, leadership, and training), and the effects of internalization (customer, people, and social results). Engineering managers can consider these aspects and associated drivers when they seek to improve the current processes and performance of their firms. On the basis of this review, this article identifies gaps in the literature and proposes future research areas.This work has been carried out as part of the research project ECO2012-36316 funded by the Science and Innovation Ministry (Plan Nacional de I+D+i)

Agility, innovation, environmental management and competitiveness in the hotel industry

The hotel industry is characterized by operating in a global, dynamic and uncertain environment where stakeholders' concerns on sustainable development are growing. However, there is limited research on whether hotels have flexibility and capacity for change, to develop environmental practices that meet stakeholder demands and improve their competitiveness. Through the dynamic capabilities theory, the resource-based view and the stakeholder theory, this paper develops a model that considers agility and innovation as antecedents of environmental management and competitive advantages as consequences. A Partial Least Squares analysis is carried out based on data from Spanish hotels. The results indicate that agility and innovation influence environmental management positively; agility influences innovation positively; and agility influences environmental management indirectly through innovation. Moreover, environmental management positively influences cost and differentiation competitive advantages. This study contributes to the literature by examining the role of two important dynamic capabilities and their impact on environmental management and showing how the interaction and mediation between these capabilities favors competitive advantages.This work was supported by the Spanish Ministry of Economy and Competitiveness (grant number ECO2015-67310P)

A Taxonomy of Quality Standard Adoption: Its Relationship with Quality Management and Performance in Tourism Organizations In Spain

This work aims to identify quality standard adoption levels and their relationship with quality management practices and performance (customer, employee and social results, and organizational performance) in tourism organizations in Spain. This work uses 279 tourism organizations in the following subsectors: hotels, travel agencies, restaurants, and rural accommodations. The work applies cluster and regression analyses. Results show three levels of adoption and a lower degree of development of the continuous improvement dimension. Organizations with a significantly lower level of development of the quality standard have started to integrate the quality requirements in their daily practices to some extent and where continuous improvement practices are little developed. These organizations have significantly lower results than those organizations with higher adoption of quality. The results also indicate that a greater level of adoption of a quality standard leads to a higher development of QM practices. These results are interesting for managers, destination managers, and the wider tourism professional community. It contributes to supplementing previous studies about taxonomies of quality standard adoption in the particular case of tourism organizations in Spain and may serve as a starting point for further research on that topic.This study has been carried out as part of research project ECO2012-36316, funded by the Spanish government (National R&D&i Plan)

Field analysis of the deterioration after some years of use of four insect-proof screens utilized in Mediterranean greenhouses

The installation of insect-proof screens on greenhouse vents is one of the principal methods of protection against harmful insects for crops. Their main disadvantage lies on their negative effects on natural ventilation and greenhouse microclimate, which have been the focus of studies by several authors. However, few works have analysed the effect of accumulated dust and dirt on these screens. The present study has analysed four anti-insect screens, comparing their geometric characteristics before installation and after three to four years of use. Two negative effects have been observed and quantified: deterioration of the threads that make up the screen and reduction of porosity due to accumulated dirt in the pores. This deterioration over time gives leads to a mean increase in thread diameter of 3.1%, as well to a mean decrease in the pore size of 6.2% and 2.3% in the weft (Lpx) and the warp (Lpy), respectively. In fact, the insect-proof screen porosity (φ) decreased due to the deterioration of the threads by an average of 6.5%, in addition to an average 20.3% reduction due to the accumulation of dirt in the pores, making a total reduction in porosity of 26.8%. This decrease in porosity leads to lower greenhouse ventilation rates, and is therefore detrimental for the greenhouse microclimate. Consequently, it is recommended that insect-proof screens in arid areas such as Almería (Spain), with abundant dust suspended in the atmosphere, be washed monthly using water sprayed at high pressure

Sexuality throughout all the stages of pregnancy: experiences of expectant mothers

Objective: To explore and understand the sexual experiences of expectant mothers during their pregnancy. Methods: The study was carried out in two healthcare centers in the Almería Health District, in southern Spain. The participants included pregnant women who received prenatal care and/or maternity education. The inclusion criteria were being pregnant, maintaining sexual activity and agreeing to participate in the study. The exclusion criteria were having limitations on sexual activity by medical prescription. The sample consisted of 15 expectant women selected using a convenience sample, of which 5 took part in a focus group (FG) and 10 in in-depth interviews (IDI). Data was collected between the months of June and December 2016. Participants were contacted by the main researcher and an appointment was made to carry out the FGs or the IDIs. Results: Three main categories emerged: False beliefs and a holistic approach to sexuality during pregnancy, which is related to the concept of sexuality, false beliefs, and limited sexual counseling during pregnancy. Limitations: From fear at the beginning to physical diffi culty at the end, referring to the fluctuations in sexual desire as well as the physical changes that limit sexual activity. Adapting to changes: safe practices and satisfaction with one’s body image, which encompasses concerns about the risks and the relationship between body image and self-esteem. Conclusion: A lack of sexual counseling during pregnancy leads to the creation of false beliefs, which, together with physical changes, concerns about the risk, and fl uctuations in sexual desire and interest, bring about a decrease in sexual activity. But sexuality remains an important aspect of pregnancy, toward which the participants must adopt a broader approach, not limited to intercourse, and adopt sexual practices that are adapted to the physical and emotional changes that happen during this time

Environmental certification, competitiveness and firm performance: a mixed method research in the hotel industry

La Responsabilidad Social en general, y la Gestión Medioambiental en particular, pueden influir sobre el resultado y la competitividad de las empresas. El objetivo principal de este trabajo es analizar la relación entre certificación medioambiental, rendimiento medioambiental, competitividad y resultado empresarial en el sector hotelero español. Además, también se analizan y comparan los niveles alcanzados de proactividad medioambiental para el grupo de hoteles certificados y no certificados. El método de investigación utilizado es híbrido, combinando una parte cualitativa con otra cuantitativa. Los resultados indican que los hoteles que tienen certificado su sistema de Gestión Medioambiental alcanzan mayores niveles de resultado en términos de porcentaje de ocupación e ingresos por habitación disponible (RevPAR). Además, los hoteles certificados obtienen un mejor rendimiento medioambiental. Con relación a la ventaja competitiva, los hoteles certificados desarrollan una ventaja en diferenciación significativamente superior.Corporate Social Responsibility in general, and environmental management in particular, may influence firm performance and competitiveness. The main aim of this paper is to analyse the relationship between environmental certification, competitiveness and firm performance in the Spanish hotel industry. In addition, this study also analyses and compares the levels of environmental pro-activity for the group of certified and non-certified hotels. We use a mixed methods design, combining two phases: qualitative and quantitative. The results indicate that the hotels that have certified its environmental management system achieve higher levels of firm performance measured in terms of occupancy rate and revenue per available room (RevPAR). Furthermore, certified hotels obtain higher environmental performance than non-certified hotels. With regard to competitive advantage, certified hotels develop a significantly higher differentiation advantage.Los autores agradecen el apoyo financiero del Ministerio de Economía y Competitividad a través del proyecto ECO2009-12231 del Plan Nacional de I+D+i
