Análisis de los concursos en redes sociales como herramienta del marketing de influencia

Los likes, las publicaciones, compartir o mencionar a un amigo, son expresiones que forman parte de nuestro día a día. Las redes sociales se han convertido en el 50% de nosotros y pasamos mucho tiempo (y cada vez más) en ellas. Debido a este aumento del uso de las redes sociales, el marketing de influencia va creciendo con el paso de los años, así como las herramientas y métodos utilizados para llegar a los consumidores. Una de esas herramientas son los concursos online o en redes sociales por los que apuestan cada vez más las empresas y que están liderados por influencers. Los concursos aumentan la actividad en los perfiles de los distintos influencers y, a través de ellos, se logra que los seguidores conozcan nuevos productos o servicios. El objetivo principal del trabajo es el análisis de los concursos de los influencers en las redes sociales más utilizadas por los usuarios y cuál es su repercusión en el comportamiento final de compra.Likes, posts, share or mention a friend, are expressions that are part of our day to day. Social networks have become 50% of us and we spend a lot of time (and more and more) in them. As a consequence of this increase in the use of social networks, influence marketing is growing over the years, as well as the tools and methods used to reach consumers. One of those tools is the online contests or social networks so companies are betting more and more, and that are led by the influencers. The contests increase the activity in the profiles of the different influencers and, through them we get fans to know new products or services, so it seems that with them we all won. The main objective of the work is the analysis of the influencers competitions in the social networks plus the applications of the users and their repercussion in the final behavior of the purchase.Departamento de Organización de Empresas y Comercialización e Investigación de MercadosGrado en Derecho y Grado en Administración y Dirección de Empresa

Cryptic diversity, intraspecific phenetic plasticity and recent geographical translocations in Branchiomma (Sabellidae, Annelida)

The importance of identifying biological diversity accurately and efficiently is becoming more evident. It is therefore critical to determine the species boundaries between closely related taxa and to establish diagnostic characters that allow us to define species. This is not an easy task when species exhibit high intraspecific phenotypic plasticity or when distinct evolutionary lineages with an unusually large amount of genetic distinctiveness show no apparent morphological diversity (cryptic species). These phenomena appear to be common in the genus of fan worms Branchiomma (Sabellidae, Annelida), and consequently, taxonomic errors are widespread in the group. Moreover, some Branchiomma species have been unintentionally translocated outside the area where natural range extension is expected, increasing the taxonomic problems. We have performed a range of analytical methods including genetic distances, Bayesian inference, maximum likelihood, maximum parsimony, statistical parsimony analyses and general mixed Yule coalescent model to clarify the taxonomic status and assess the species boundaries of Branchiomma in Australia. This study shows that the traditional diagnostic morphological features are greatly homoplastic. Results also indicate that the diversity of Branchiomma in Australia is higher than previously reported and evidence some cases of high phenetic plasticity (in features previously considered as stable within species), high intraspecific genetic variability, cryptic species and several unexpected cases of translocations.© 2013 The Norwegian Academy of Science and Letters.This project was funded by an Australian Biological Resources Study (ABRS)/AM and Census of Marine Life (CReefs) grants to PH and MC.

Phylogeny of Oweniidae (Polychaeta) based on morphological data and taxonomic revision of Australian fauna

The family Oweniidae Rioja, 1917 is a small group of broadly distributed polychaetes whose relationships and position in the annelid tree are still poorly understood. A comprehensive revision of the group with reconsideration of character homologies and terminology under a phylogenetic framework was needed. We investigated the relationships of members of Oweniidae and other polychaetes by performing maximum parsimony analyses of 18 oweniid species of the five recognized genera to date and members of the families Siboglinidae, Sabellidae, Spionidae, Magelonidae, and Chaetopteridae. Phylogenetic hypotheses confirmed the monophyly of Oweniidae and suggested sister-group relationships with Magelonidae, although weakly supported. Analyses also recovered Oweniaand Myriowenia as monophyletic and allowed recognition of Myrioglobulaas a junior synonym of Myriochele based on the presence of acicular chaetae and the shape of the head. Implied weighting analyses supported these findings and recovered Galathowenia australis as sister group ofMyriochele. The presence of acicular chaetae justifies the consideration of this species as belonging to Myriochele. Nomenclatural changes are proposed for those species previously considered as members ofMyrioglobula, and these are: Myriochele antarcticacomb. nov., Myriochele japonicacomb. nov., Myriochele islandicacomb. nov., Myriochele malmgrenicomb. nov., and Myriochele australiscomb. nov. After analyses and definition of generic diagnostic features, other new combinations include Galathowenia eurystomacomb. nov. and Galathowenia haplosomacomb. nov., previously considered as members of Myriochele. Taxonomic revision of Australian collections revealed the presence ofMyriochele heruensis Gibbs, 1971, which is herein redescribed, and allowed the description of four new species: Galathowenia annae sp. nov.,Galathowenia arafurensissp. nov., Galathowenia quelissp. nov., andMyriochele australiensissp. nov., mostly from the east coast of Australia, in addition to the three recently well-documented species of Owenia. Australian species have been described, illustrated, and compared in detail with similar taxa. Distribution patterns and ecological notes have also been given.

Sphaerodoridae (Annelida) of the deep Northwestern Atlantic, including remarkable new species of Euritmia and Sphaerephesia

Sphaerodoridae (Annelida) is a seeming uncommon and minimally diverse group of polychaetes in the northwestern Atlantic, with only seven species reported from the United States, and none from the eastern coast of Canada, before the present study. Review of the large Smithsonian collection (National Museum of Natural History, Washington) revealed the presence of two morphologically extraordinary undescribed species and added a new record to the north-western Atlantic region. Euritmia carolensis sp. n. is characterised by bearing approximately 20 sessile spherical papillae arranged in three transverse rows per segment, ventrum with 4–6 larger papillae near the parapodial bases and parapodia without papillae; bearing 4–5 simple chaetae that are enlarged subdistally. Sphaerephesia amphorata sp. n. is distinguished from other congeners in the presence of four longitudinal rows of sessile, bottle-shaped macrotubercles with exceptionally long digitiform terminal papilla, and parapodia with four rounded and small papillae, bearing 4–7 compound chaetae, with blades 7–11 times as long as wide. Other encountered species are also herein re-described, including intraspecific variation and updated iconography. Comparison of material also allowed some systematic changes in the group, including the synonymisation of the genus Amacrodorum with Euritmia, and the transfer of Ephesiopsis shivae to Ephesiella. A key to the species reported from the Northwestern Atlantic is provided.SEMs were taken in Museo Nacional de Ciencias Naturales de Madrid during a European Commission Taxonomic Initiative SYNTHESYS (ESTAF-2839)Peer reviewe

Proactive project scheduling in an R&D department: a bi-objective genetic algorithm

In this paper, we present part of a study on stochastic, dynamic project scheduling in an R&D Department of a leading home appliances company in Turkey. The problem under consideration is the preemptive resource constrained multi-project scheduling problem with generalized precedence relations in a stochastic and dynamic environment. The model consists of three phases. Phase I of the model provides a systematic approach to assess uncertainty resulting in activity deviation distributions. In Phase II, proactive project scheduling is accomplished through two different scheduling approaches,which employ a bi-objective genetic algorithm. Phase III is the reactive project scheduling phase aiming at rescheduling the disrupted project activities. Here, we will limit our presentation to Phase II – the proactive project scheduling phase. The procedure is demonstrated through an implementation with real data covering 37 R&D projects. Computational study is performed to compare the two different scheduling approaches called single and multi-project scheduling approaches, as well as two different chromosome evaluation heuristics. Results are presented and discussed

Uncertainty assessment in project scheduling with data mining

During project execution, especially in a multi-project environment project activities are subject to risks that may cause delays or interruptions in the baseline schedules. This paper considers the resource constrained multi-project scheduling problem with generalized activity precedence relations requiring multi-skilled resources in a stochastic and dynamic environment present in the R&D department of a home appliances company and introduces a two-phase model incorporating data mining and project scheduling techniques. This paper presents the details of Phase I, uncertainty assessment phase, where Phase II corresponds to proactive project scheduling module. In the proposed uncertainty assessment approach models are developed to classify the projects and their activities with respect to resource usage deviation levels. In doing so, the proposed approach enables the project managers not only to predict the deviation level of projects before they actually start, but also to take needed precautions by detecting the most risky projects. Moreover, Phase I generates one of the main inputs of Phase II to obtain robust baseline project schedules and identifies the risky activities that need close monitoring. Details of the proposed approach are illustrated using R&D project data of a leading home appliances company. The results support the efficiency of the proposed approach

EFECTO DE LA CUBIERTA (MICROTÚNEL) EN LA PRODUCTIVIDAD DE DOS VARIEDADES DE FRESA (Fragaria vesca) EN EL SECTOR CAJANUMA CANTÓN LOJA

La fresa (Fragaria vesca) es un cultivo de gran aceptación a nivel mundial, no siendo la excepción en Ecuador. La mayor parte de la producción se realiza a campo abierto, haciendo que existan limitaciones por el ataque de factores bióticos y la influencia de factores abióticos, generando pérdidas en la producción. El presente trabajo se planteó en la provincia de Loja al no existir información precisa de este cultivo e investigaciones sobre el uso de sistemas protegidos (microtúnel). El objetivo principal fue evaluar el efecto de la producción de fresa en los dos sistemas de producción (Campo abierto y microtúnel), con variedades Albion y Monterey; además analizar el costo y rentabilidad de la producción. El sistema a campo abierto fue considerado como un tratamiento testigo para su evaluación frente al de microtunel. El experimento se realizó en la Estación Agropecuaria de la Universidad Técnica Particular de Loja, bajo condiciones de microtúnel y campo abierto, en la cuales se comparó el desarrollo fenológico y productivo de la fresa. Los resultados encontrados en el estudio en los dos sistemas a campo abierto y microtúnel no presentaron una diferencia estadística en las variables fisiológicas evaluadas, concluyendo que la cubierta con microtúnel al cultivo no influyó en el desarrollo en las dos variedades. En relación al análisis de costos-beneficio de la producción, este fue superior en el sistema microtúnel, la inversión fue más fuerte al inicio, sin embargo, se debe indicar que existen varias ventajas productivas en relación con campo abierto, generando beneficios al productor de fresa. Palabras clave: Fresa, Microtúnel, producción, rendimiento, rentabilidad.//The strawberry (Fragaria vesca) is a crop of great acceptance worldwide. In Ecuador, most of the production is done in open field, presenting limitations by the attack of biotic factors and abiotic factors that generate losses in the production. This research was carried out in the province of Loja, since there was no precise information on this crop, and research on the use of protected systems (low tunnels). The main objective of the study was to evaluate the effect of strawberry production on the two production systems (open field and low tunnels), with Albion and Monterey varieties, as well as to analyze the costs and profitability of production. The experiment was conducted at the Agricultural Station of Universidad Técnica Particular de Loja, under low tunnels and open field conditions, in which the phenological and productive development of the strawberry was compared. The results found in the study in the two open field and low tunnel systems did not present a statistical difference in the physiological variables evaluated, which allow to conclude that the low tunnel cover on the crop did not influence the development of the two varieties. In relation to the cost-benefit analysis of production, it was higher in the low tunnel system, the investment was stronger at the beginning, but it must be indicated that there are several productive advantages in relation to the open field that generate benefits for the strawberry producer

The Role of Secondary Airports for Today's Low-Cost Carrier Business Models: The European Case

One of the core characteristics of Low-Cost Carriers (LCCs) is their use of secondary and regional airports. However, nothing is fixed as the market constantly evolves and carriers modify their strategies in order to achieve growth. This paper uses the examples of Ryanair, easyJet and Norwegian to show how changes to LCC business models are affecting secondary airports across Europe. Using a content analysis, this paper first describes how airport choice factors for LCCs have evolved over the last 10 years. This is followed by a data analysis of historical and current airline network capacity to identify how LCC traffic at secondary airports is developing. The paper finds that cost, demand and efficiency are still the most important criteria for LCCs when choosing an airport to operate from. However, it also identifies that LCCs have become more interested in serving business passengers, which is why they are increasingly using primary airports (accounting for 58% of their recent capacity growth). Through the use of a selection of case airports it is finally concluded that the evolution of LCCs increases competition between primary and secondary gateways. In most cases, secondary airports are losing a significant amount of LCC traffic and only sustain flights to less important destinations. This research puts into question the future importance of secondary airports for LCCs. As not all airports have been impacted by the hybridisation of LCCs to the same extent, the results are not equally applicable to the whole European airport industry
