Shaping inter-firm collaboration in new product development in the automobile industry: A trade-off between a transaction and relational-based approa…
2008
Abstract Shaping collaboration in the new product development (NPD) has always been a very difficult task, especially in complex industries like the automobile one. This complexity is particularly true during the engineering phase of the NPD process, where different complex systems are to be designed in a collaborative way. Basically, two-kind of approaches have been observed in the literature and industry: one is more related to market transactions, specifically the west car-company style, the other is more relational based, as in the Japanese car-company style. Now, the increasing globalisation of the industry asks for a merge of the two approaches; indeed, the increasing use of standard …
New economic geography and economic history: a survey of recent contributions through the lens of the Spanish industrialization process
2021
This paper aims to provide a synthesis of a number of articles that over the last few years have explored the industrialization process in Spain from the perspective of the new economic geography (NEG). To this end, we present some of the seminal theoretical papers of the NEG literature from which originated the main theoretical predictions that have been tested through empirical analysis applied to the case of Spain. We also look at those papers on the economic history of Spain that through the use of an economic geography framework have analysed how the location and regional concentration of manufacturing has evolved over the years. Altogether, this paper aims not only to present the dete…
Motivations, adoption and impact of voluntary environmental certification in the Italian Forest based industry: The case of the FSC standard
2017
Abstract Over the past few years several private voluntary schemes have been developed worldwide to address the environmental issues in the forest based industry. Using survey data, this study analyse the main factors motivating companies operating in the Italian forest based industry to implement FSC (Forest Stewardship Council) standard, as a tool to promote responsible forest management and traceability of derived products, and the impact of this standard on the economic and organisational results. The findings provide evidences that signalling mechanisms drive the entrepreneurs towards the adoption of FSC certification, followed by moral and ethical reasons. In terms of impact, emerges …
Analysis of enniatins and beauvericin by LC-MS/MS in wheat-based products
2017
Due to the matrix complexity for wheat-based products, a comparative study of different rapid extraction procedures was performed for the extraction of enniatins (ENA, ENA1, ENB, ENB1) and beauvericin in flour, pasta, breakfast cereals, and biscuits. Three different approaches were studied during the extraction and purification steps (shaker, Ultra-Turrax, and QuEChERS) for each matrix. Liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) with electrospray source working in a positive mode was used. For the analysis of the five mycotoxins, the three methods were tested in terms of recovery, matrix effect, and sensibility, concluding that Ultra-Turrax extraction was the most …
Performance of a pilot-scale biotrickling filter in controlling the volatile organic compound emissions in a furniture manufacturing facility.
2009
A 0.75-m3 pilot-scale biotrickling filter was run for over 1 yr in a Spanish furniture company to evaluate its performance in the removal of volatile organic compounds (VOCs) contained in the emission of two different paint spray booths. The first one was an open front booth used to manually paint furniture, and the second focus was an automatically operated closed booth operated to paint pieces of furniture. In both cases, the VOC emissions were very irregular, with rapid and extreme fluctuations. The pilot plant was operated at an empty bed residence time (EBRT) ranging from 10 to 40 sec, and good removal efficiencies of VOCs were usually obtained. When a buffering activated carbon prefil…
Hydrolysis rates, methane production and nitrogen solubilisation of grey waste components during anaerobic degradation.
2005
Abstract Municipal grey waste (i.e. the remaining fraction in municipal waste management systems in which putrescibles (biowaste) and other recyclables (paper, metals, glass) are source-segregated) was manually sorted into six main fractions on the basis of composition and also separated by sieving (100 mm mesh size) into two fractions, oversized and undersized, respectively. In practice, in waste management plant the oversized fraction is (or will be) used to produce refuse-derived fuel and the undersized landfilled after biological stabilisation. The methane yields and nitrogen solubilisation of the grey waste and the different fractions (all studied samples were first milled to 5 mm part…
Physics of agarose fluid gels: Rheological properties and microstructure
2021
Agarose, a strongly gelling polysaccharide, is a common ingredient used to optimize the viscoelastic properties of a multitude of food products. Through aggregation of double helices via hydrogen bonds while cooling under quiescent conditions it forms firm and brittle gels. However, this behavior can be altered by manipulating the processing conditions viz shear. For example, gelation under shear leads to microgel particles with large surface area, which in turn leads to completely different rheological properties and texture. Such fluid gels are shown to play an important role in texture modification of foods and beverages for dysphagia patients. In this study, different concentration of a…
Microbial Ecology of Retail Ready-to-Eat Escarole and Red Chicory Sold in Palermo City, Italy
2019
Background: Ready-To-Eat (RTE) foods include any edible food that is commonly consumed raw. This study aimed at evaluation of microbial ecology of retail RTE escarole and red chicory sold in Palermo city, Italy. Methods: A total of 32 mono-varietal RTE samples, including escarole (n=16) and red chicory (n=16) samples were obtained from Palermo, Italy. Both RTE vegetables at expiry date were analyzed to quantify spoilage bacteria, pathogenic bacteria, and yeast. All different colonies were isolated and identified on the basis of phenotypic characteristics and genetic polymorphisms by random amplification of polymorphic DNA-Polymerase Chain Reaction (PCR) and further genotype by sequencing th…
Reproducibility and relative validity of a newly developed web-based food-frequency questionnaire for assessment of preconception diet
2019
Abstract Background The importance of diet and nutrition during preconception age is a window of opportunity to promote future parental and transgenerational health. As a sub-study to a large Norwegian study, ‘Diet today – health of tomorrow’, a food-frequency questionnaire (FFQ) was developed to assess diet during the preconception phase in young adults aged 20 – 30 years and in this paper we report the reproducibility and relative validity of this questionnaire. Methods The FFQ was developed from an existing FFQ validated in adolescents. Participants were recruited on social media and at a university. Reproducibility was assessed by comparing the test and retest of the FFQ. Relative valid…
Capilaridad de la manufactura textil en la Plana de Castelló. El caso de Onda en el siglo XV
2010
Onda, a locality with an oscillating population between 300 and 600 dwellings in the 15th century and with Moslems and Jews in the local work, becomes a new piece of the puzzle that lets us see the capillarity of the wool textile manufacture in “La Plana de Castelló”. This capillarity can be seen in the production of clothes, just like in the raw material trade or in the movement of craftsmen. To approach this situation we have basically used the series of documents of the judge of the village kept in the “Archivo del Reino de Valencia”.<br><br>Onda, localidad con un volumen demográfico oscilante entre 300-600 fuegos en el transcurso del siglo XV, con presencia de mudéjares y ju…
