A performance measurement system for managing mass production and mass customisation contexts

[ENG] In supply chain/networks (SC/N) operating under a mass customisation (MC) strategy, i.e. producing customised products at a price close to that of mass production, real- time and cooperativeness receive special emphasis in order to improve customer responsiveness. The main difference between MC and Mass Production (MP) lies in their logic of operating. For MP, lower prices lead to greater sales; greater sales in higher volumes, higher volumes in lower costs, and lower cost translate into lower prices. Nevertheless, in MC, customisation leads to more satisfied customers and innovation, which both lead to greater sales and higher profits and understanding of customer needs. Thus, MP is efficiency-driven and based in economies of scale while MC is customer-driven and based on offering higher variety of products at affordable prices. This difference of logic is reflected in the processes involved in each approach. Even though both approaches, MC and MP, rely on the same processes i.e. collaborative order management, collaborative planning and scheduling processes in a SC/N context, the degree of interaction among all three processes depend on the strategy followed (MP or MC) as MC demands that all three processes react and adapt when an new customer order is received. Therefore, as both strategies differ considerably in the way they are implemented, the performance measurement systems (PMS) developed for MP need to be adapted to be used for MC. In fact, this situation is even more complex in the case where the same SC/N operates at both strategies, MP and PC, at the same time for different products. For example, in the current business environment, some enterprises usually operating under a MP approach are deciding to assign part of the available capacity of standard products (MP) to configurable products (MC). Then, PMS should evolve and integrate both approaches together in order to reflect the real situation of the SC/N. In order to deal with the management of both types of products under the same PMS, it is necessary to develop a structure that considers both situations and follows a process-based approximation to manage the processes involved. The purpose of this paper is to introduce a PMS for both contexts, called Mass Production/Mass Customisation-Performance Measurement System (MP/MC-PMS) that fills this research gap by including all three characteristics within its structure in order to provide a tool for managing the performance of MP and MP contexts more efficiently and effectively.This work has been developed within the framework of a research project funded by the Spanish Ministry of Education and Science, reference DPI2008-06788-C02-01, and title “PERMACASI- Mass Customisation through Intelligent Supply Chains, with Products of complex and changing Structure/Bill of Materials and Manufacturing Processes”

Depositional history of estuarine infill during the last postglacial transgression (Gulf of Cadiz, Southern Spain)

The Late Pleistocene and Holocene evolution of the estuaries in the Gulf of Cadiz is interpreted for the first time using drill cores, logs, trenches, and 38 new radiocarbon data, and the results compared with the shelf. The Odiel, Tinto and Guadalete Rivers deposited conglomerates during a highstand that did not reach the present sea level dated at ca. 25–30 ka (Isotopic Stage (IS) 3), corresponding to a relatively humid period in the area. Rivers incised these coarse-grained deposits during the last main lowstand at ca. 18 ka, when sea level dropped to -- 120 m and the coastline lay 14 km seawards from the present. The erosional surface is a sequence boundary and the flooding surface of the postglacial eustatic rise, overlain by the valley fill deposits of the transgressive and highstand phases of the last fourth- and fifth-order depositional sequences recognised in the shelf. The first marine influence in the estuaries during the transgression occurs at -25/-30 m at. ca. 10,000 years BP. According to fossil assemblages, the transgressed basins changed from brackish to more open marine as the sea rose until ca. 6500 years BP, when it reached the maximum flooding and the sandy estuarine barriers ceased to retrograde toward the muddy central basins. Then, the rate of eustatic rise decreased drastically, and the estuarine filling followed a two-fold pattern governed by the progressive change from vertical accretion to lateral (centripetal) progradation. At ca. 4000 years BP the fluvial input surpassed the already negligible rate of rise, causing partial emergence of tidal flats and spit barriers in the largely filled estuarine basins. Prevalence of coastal progradation upon vertical accretion at ca. 2400 years BP caused accelerated expansion of tidal flats and rapid growth of the sandy barriers. Further changes since the 16th century reflect widespread anthropic impacts. q2000 Elsevier Science B.V. All rights reserved

The associations between plasma levels of omega-6 and omega-3 polyunsaturated fatty acid–derived oxylipins and body composition and cardiometabolic risk factors in young adults were assessed. Methods: Body composition, brown adipose tissue, traditional serum cardiometabolic risk factors, inflammatory markers, and a panel of 83 oxylipins were analyzed in 133 young adults (age 22.1[SD 2.2] years, 67% women). Results: Plasma levels of four omega-6 oxylipins (15-HeTrE, 5-HETE, 14,15-EpETrE, and the oxidative stress–derived 8,12-iso- iPF2α -VI) correlated positively with adiposity, prevalence of metabolic syndrome, fatty liver index, and homeostatic model assessment of insulin resistance index and lipid parameters. By contrast, the plasma levels of three omega-3 oxylipins (14,15-DiHETE, 17,18-DiHETE, and 19,20-DiHDPA) were negatively correlated with adiposity, prevalence of metabolic syndrome, fatty liver index, homeostatic model assessment of insulin resistance index, and lipid parameters. The panel of seven oxylipins predicted adiposity better than traditional inflammatory markers such as interferon gamma or tumor necrosis factor-alpha. Pathway analyses revealed that individuals with obesity had higher plasma levels of omega-6 and lower plasma levels of omega-3 oxylipins than normal-weight individuals. Conclusion: Plasma levels of seven omega-6 and omega-3 oxylipins may have utility as early markers of cardiometabolic risk in young adults.Spanish Government PI13/01393Retos de la Sociedad DEP2016-79512-REuropean Commission Spanish Government FPU16/02828 FPU19/01609Fundacion Iberoamericana de Nutricion (FINUT)Redes Tematicas de Investigacion Cooperativa RETIC Red SAMID RD16/0022AstraZenecaUniversity of Granada Plan Propio de Investigacion Excellence actions: Unit of Excellence on Exercise and Health (UCEES)Junta de Andalucia Consejeria de Conocimiento, Investigacion y Universidades (ERDF) SOMM17/6107/UGR DOC 01151Fundacion Alfonso Martin EscuderoNetherlands CardioVascular Research Initiative: the Dutch Heart FoundationDutch Federation of University Medical CentersNetherlands Organization for Health Research and DevelopmentRoyal Netherlands Academy of Sciences CVON2017-20 GENIUS-2China Scholarship Council 201707060012 PTA-1226

Holocene aeolian phases and human settlements along the Atlantic coast of southern Spain

A combined geomorphological, radiocarbon dating, archaeological and historical approach permits a refining of the age of the coastal dune systems related to estuaries in the Gulf of Cadiz. Three dune systems are distinguished in this paper. The oldest one, DI, which accumulated under prevailing WSW winds during the first millennium BC, overlays both the occupational horizons of Late Neolithic-Early Copper Age (fourth millennium BC) and the 'lithic workshop levels' (fourth to second millennia BC). The middle dune system, D2, containing both Roman and medieval remains, accumulated between the thirteenth or fourteenth centuries and the seventeenth century AD. The youngest D3 system is associated with the time of building of watchtowers in the seventeenth century AD but extends to the present; it is related to SW prevailing winds. We explain the absence of aeolian deposits prior to ~2700 cal. BP as the result of trapping of a large part of the sediment supply in the estuaries, which starved the neighbouring beaches and aeolian settings. Aeolian accumulation reached significant values when sedimentation in the coastal zone changed from being mainly aggradational in the estuaries (~6500~2700 cal. BP) to mainly progradational in spit barriers and related dunes (post ~2700 cal. BP). The present analysis of aeolian systems suggests a non-direct correlation, at least in some cases, between coastal progradation of spit barriers and aridity

Tsunami vs. storm surge deposits: a review of the sedimentological and geomorphological records of extreme wave events (EWE) during the Holocene in the Gulf of Cadiz, Spain

The Gulf of Cadiz region of Spain has undergone many studies examining Holocene tsunami and storm deposists. Some of the studies aimed at determining recurrence intervals of events interpreted of tsunamigenic origin. A review of geomorphologic, sedimentary and paleontological features of these deposits suggests that only a few of them can be accurately ascribed to tsunami events; instead, most of them lack conclusive evidence of a tsunamigenci genesis and should be referred to as generated by extreme wave events (EWE

Landscape evolution and geodynamic controls in the Gulf of Cadiz (Huelva coast, SW Spain) during the Late Quaternary

The coastal evolution of the El Abalario area (Huelva, southern Spain) during the Late Pleistocene and Holocene is reinterpreted after a refinement of the available geochronology by means of optically stimulated luminescence (OSL) dating. New data come from the analysis of soft sediment deformation, palaeosols, geomorphological mapping, and published seismic surveys on the onshore and offshore Gulf of Cadiz. The present structure of El Abalario dome resulted from the complex interaction of littoral-catchment processes and sea-level changes upon an emergent coastal plain, conditioned by the upwarping of the underlying Pliocene - Pleistocene prograding deltaic sequence. Upwarping is probably related to escape of over-pressurized fluids, accompanied by dewatering, prior to (?) and during OIS (Oxygen Isotopic Stage) 5. Continued upwarping produced the large NW - SE gravitational fault of Torre del Loro (TLF) in the southwestern flank of the dome, roughly parallel to the present coastline during OIS 5 - OIS 4. The resulting escarpment favoured the accumulation of aeolian sand dunes (units U1, U2, and U3) from OIS 5 to early OIS 1. Unit U1 (OIS 5) ends upwards in a supersurface with a thick weathering profile that suggests moist and temperate climatic conditions. Unit U2 accumulated mainly during OIS 4 and OIS 3 with prevailing W/E winds. The supersurface between U2 and U3 records a part of OIS 2, with relative low sea level. Sedimentation of unit U3 took place during the Last Deglaciation (radiocarbon and OSL ages) with prevailing W/SW winds, under a temperate moist climate, that became more arid towards the top (Holocene). A major supersurface with an iron crust-like layer (SsFe) developed during the Holocene Climatic Optimum (OIS 1) under wetter and more temperate conditions than before, fossilizing the TLF. The supersurface is covered by younger aeolian dunes (U4, U5, U6, and U7) transported by W - SW winds since the Late Neolithic - Chalcolithic cultural period (̃5.0 ky cal BP).Financial support from Spanish Projects BTE2002-1065 and BTE2002-1691.

RETOS Y OPORTUNIDADES EN LA INTEGRACIÓN DE SOCIEDADES COOPERATIVAS

La presente publicación contiene las actas del Curso de Verano titulado “Retos y oportunidades en la integración de cooperativas” que se celebró en la sede de la Cartuja de Sevilla de la Universidad Internacional de Andalucía (UNIA) entre los días 11 a 15 de septiembre de 2017 y que se organizó en el marco del Proyecto Investigación de Excelencia de la Junta de Andalucía "Retos y oportunidades en la concentración e integración de empresas agroalimentaria" (P12-SEJ-2555) del que el profesor Vargas Vasserot es el Investigador Principal. Una de las peculiaridades que tuvo el curso es que gran parte de los asistentes eran a su vez especialistas en las materias impartidas y miembros del proyecto de investigación de la Junta de Andalucía que organizaba el curso, por lo que con objeto de darle mayor participación se habilitó la posibilidad de presentar comunicaciones científicas, como si fuera un congreso. Una vez terminado el curso, se vio que los materiales facilitados a los alumnos por los distintos profesores del curso junto a las comunicaciones científicas presentadas por parte de los asistentes era un material que debía ser puesto a disposición de todas las personas e instituciones interesadas en los procesos de integración de cooperativas y, además, sin mucha demora por la importancia que actualmente tienen todas estas cuestiones. Además de las ponencias y comunicaciones que se presentarons, hemos includio en la publicación un anexo con legislación y normativa de interés y los resultados de una encuesta sobre los procesos de integración realizada en el sector hortofrutícola almeriense que realizamos a lo largo de 2016 en el marco del citado proyecto de investigación de la Junta de Andalucía
