Personality, risky health behavior, and perceived susceptibility to health risks

We examined the relations between personality (Five-Factor Model), risky health behaviours, and perceptions of susceptibility to health risks among 683 university students. The hypothesis was that personality would affect perceptions of susceptibility to health risks in two ways: directly, irrespective of risky health behaviours, and indirectly, through the effects of personality on risky health behaviours. The students were surveyed about smoking, being drunk, drunk driving, risky sexual behaviour, and perceptions of susceptibility to related health risks. In path-analytical models we found the expected direct and indirect effects. The personality dimensions of Agreeableness and Conscientiousness had negative direct effects on perceptions of susceptibility as well as negative indirect effects through risky health behaviours. Neuroticism was the only personality dimension to show positive direct effects on perceptions of susceptibility as well as negative indirect effects.

An updated synthesis of the observed and projected impacts of climate change on the chemical, physical and biological processes in the oceans

The 5th Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC) states with very high certainty that anthropogenic emissions have caused measurable changes in the physical ocean environment. These changes are summarized with special focus on those that are predicted to have the strongest, most direct effects on ocean biological processes; namely, ocean warming and associated phenomena (including stratification and sea level rise) as well as deoxygenation and ocean acidification. The biological effects of these changes are then discussed for microbes (including phytoplankton), plants, animals, warm and cold-water corals, and ecosystems. The IPCC AR5 highlighted several areas related to both the physical and biological processes that required further research. As a rapidly developing field, there have been many pertinent studies published since the cut off dates for the AR5, which have increased our understanding of the processes at work. This study undertook an extensive review of recently published literature to update the findings of the AR5 and provide a synthesized review on the main issues facing future oceans. The level of detail provided in the AR5 and subsequent work provided a basis for constructing projections of the state of ocean ecosystems in 2100 under two the Representative Concentration Pathways RCP4.5 and 8.5. Finally the review highlights notable additions, clarifications and points of departure from AR5 provided by subsequent studies.

Land use intensification alters ecosystem multifunctionality via loss of biodiversity and changes to functional composition

Global change, especially land-use intensification, affects human well-being by impacting the deliv-ery of multiple ecosystem services (multifunctionality). However, whether biodiversity loss is amajor component of global change effects on multifunctionality in real-world ecosystems, as inexperimental ones, remains unclear. Therefore, we assessed biodiversity, functional compositionand 14 ecosystem services on 150 agricultural grasslands differing in land-use intensity. We alsointroduce five multifunctionality measures in which ecosystem services were weighted according torealistic land-use objectives. We found that indirect land-use effects, i.e. those mediated by biodi-versity loss and by changes to functional composition, were as strong as direct effects on average.Their strength varied with land-use objectives and regional context. Biodiversity loss explainedindirect effects in a region of intermediate productivity and was most damaging when land-useobjectives favoured supporting and cultural services. In contrast, functional composition shifts,towards fast-growing plant species, strongly increased provisioning services in more inherentlyunproductive grasslands.

Shifts in microbial communities do not explain the response of grassland ecosystem function to plant functional composition and rainfall change

Ecosystem functioning in grasslands is regulated by a range of biotic and abiotic factors, and the role of microbial communities in regulating ecosystem function has been the subject of much recent scrutiny. However, there are still knowledge gaps regarding the impacts of rainfall and vegetation change upon microbial communities and the implications of these changes for ecosystem functioning. We investigated this issue using data from an experimental mesotrophic grassland study in south-east England, which had been subjected to four years of rainfall and plant functional composition manipulations. Soil respiration, nitrogen and phosphorus stocks were measured, and the abundance and community structure of soil microbes were characterised using quantitative PCR and multiplex-TRFLP analysis, respectively. Bacterial community structure was strongly related to the plant functional composition treatments, but not the rainfall treatment. However, there was a strong effect of both rainfall change and plant functional group upon bacterial abundance. There was also a weak interactive effect of the two treatments upon fungal community structure, although fungal abundance was not affected by either treatment. Next, we used a statistical approach to assess whether treatment effects on ecosystem function were regulated by the microbial community. Our results revealed that ecosystem function was influenced by the experimental treatments, but was not related to associated changes to the microbial community. Overall, these results indicate that changes in fungal and bacterial community structure and abundance play a relatively minor role in determining grassland ecosystem function responses to precipitation and plant functional composition change, and that direct effects on soil physical and chemical properties and upon plant and microbial physiology may play a more important role.

The Role of Goods Trade Networks for Services Trade Volume

In this paper, we address the role of countries’ goods-trade networks for their services-trade volume. The paper employs a large cross section of bilateral trade data on aggregate cross-border goods and services sales and illustrates that the depth and overlap of two countries’ services networks induce a positive direct impact on their services-trade volume. The evidence takes into account that goods trade flows and networks are potentially endogenous so that the estimated direct effects support a causal interpretation. We find that the magnitude of the multilateral goods-trade network effect on the bilateral services-trade volume is much larger than that of bilateral goods-trade volume.

Reefs shift from net accretion to net erosion along a natural environmental gradient

Coral reefs persist in an accretion-erosion balance and ocean acidification resulting from anthropogenic CO2 emissions threatens to shift this balance in favor of net reef erosion. Corals and calcifying algae, largely responsible for reef accretion, are vulnerable to environmental changes associated with ocean acidification, but the direct effects of lower pH on reef erosion has received less attention, particularly in the context of known drivers of bioerosion and natural variability. This study examines the balance between reef accretion and erosion along a well-characterized natural environmental gradient in Kane'ohe Bay, Hawai'i using experimental blocks of coral skeleton. Comparing before and after micro-computed tomography (µCT) scans to quantify net accretion and erosion, we show that, at the small spatial scale of this study (tens of meters), pH was a better predictor of the accretion-erosion balance than environmental drivers suggested by prior studies, including resource availability, temperature, distance from shore, or depth. In addition, this study highlights the fine-scale variation of pH in coastal systems and the importance of microhabitat variation for reef accretion and erosion processes. We demonstrate significant changes in both the mean and variance of pH on the order of meters, providing a local perspective on global increases in pCO2. Our findings suggest that increases in reef erosion, combined with expected decreases in calcification, will accelerate the shift of coral reefs to an erosion-dominated system in a high-CO2 world. This shift will make reefs increasingly susceptible to storm damage and sea-level rise, threatening the maintenance of the ecosystem services that coral reefs provide.

Impacts of food availability and pCO2 on planulation, juvenile survival, and calcification of the azooxanthellate scleractinian coral Balanophyllia elegans

Ocean acidification, the assimilation of atmospheric CO2 by the oceans that decreases the pH and CaCO3 saturation state (Omega) of seawater, is projected to have severe adverse consequences for calcifying organisms. While strong evidence suggests calcification by tropical reef-building corals containing algal symbionts (zooxanthellae) will decline over the next century, likely responses of azooxanthellate corals to ocean acidification are less well understood. Because azooxanthellate corals do not obtain photosynthetic energy from symbionts, they provide a system for studying the direct effects of acidification on energy available for calcification. The solitary azooxanthellate orange cup coral Balanophyllia elegans often lives in low-pH, upwelled waters along the California coast. In an 8-month factorial experiment, we measured the effects of three pCO2 treatments (410, 770, and 1220 µatm) and two feeding frequencies (3-day and 21-day intervals) on "planulation" (larval release) by adult B. elegans, and on the survival, skeletal growth, and calcification of newly settled juveniles. Planulation rates were affected by food level but not pCO2. Juvenile mortality was highest under high pCO2 (1220 µatm) and low food (21-day intervals). Feeding rate had a greater impact on calcification of B. elegans than pCO2. While net calcification was positive even at 1220 µatm (~3 times current atmospheric pCO2), overall calcification declined by ~25-45%, and skeletal density declined by ~35-45% as pCO2 increased from 410 to 1220 µatm. Aragonite crystal morphology changed at high pCO2, becoming significantly shorter but not wider at 1220 µatm. We conclude that food abundance is critical for azooxanthellate coral calcification, and that B. elegans may be partially protected from adverse consequences of ocean acidification in habitats with abundant heterotrophic food.

Seawater carbonate chemistry during experiments with Littorina littorea, 2007

We demonstrate that acidified seawater can have indirect biological effects by disrupting the capability of organisms to express induced defences, hence, increasing their vulnerability to predation. The intertidal gastropod Littorina littorea produced thicker shells in the presence of predation (crab) cues but this response was disrupted at low seawater pH. This response was accompanied by a marked depression in metabolic rate (hypometabolism) under the joint stress of high predation risk and reduced pH. However, snails in this treatment apparently compensated for a lack of morphological defence, by increasing their avoidance behaviour, which, in turn, could affect their interactions with other organisms. Together, these findings suggest that biological effects from ocean acidification may be complex and extend beyond simple direct effects.

Seawater carbonate chemistry and nutrient fluxes during experiments with brittlestar Amphiura filiformis, 2009

Rising levels of atmospheric carbon dioxide and the concomitant increased uptake of this by the oceans is resulting in hypercapnia-related reduction of ocean pH. Research focussed on the direct effects of these physicochemical changes on marine invertebrates has begun to improve our understanding of impacts at the level of individual physiologies. However, CO2-related impairment of organisms' contribution to ecological or ecosystem processes has barely been addressed. The burrowing ophiuroid Amphiura filiformis, which has a physiology that makes it susceptible to reduced pH, plays a key role in sediment nutrient cycling by mixing and irrigating the sediment, a process known as bioturbation. Here we investigate the role of A. filiformis in modifying nutrient flux rates across the sediment-water boundary and the impact of CO2- related acidification on this process. A 40 day exposure study was conducted under predicted pH scenarios from the years 2100 (pH 7.7) and 2300 (pH 7.3), plus an additional treatment of pH 6.8. This study demonstrated strong relationships between A. filiformis density and cycling of some nutrients; activity increases the sediment uptake of phosphate and the release of nitrite and nitrate. No relationship between A. filiformis density and the flux of ammonium or silicate were observed. Results also indicated that, within the timescale of this experiment, effects at the individual bioturbator level appear not to translate into reduced ecosystem influence. However, long term survival of key bioturbating species is far from assured and changes in both bioturbation and microbial processes could alter key biogeochemical processes in future, more acidic oceans.

Seawater carbonate chemistry and coverage and dry weight of Ecklonia radiata during experiments, 2010

Predictions about the ecological consequences of oceanic uptake of CO2 have been preoccupied with the effects of ocean acidification on calcifying organisms, particularly those critical to the formation of habitats (e.g. coral reefs) or their maintenance (e.g. grazing echinoderms). This focus overlooks the direct effects of CO2 on non-calcareous taxa, particularly those that play critical roles in ecosystem shifts. We used two experiments to investigate whether increased CO2 could exacerbate kelp loss by facilitating non-calcareous algae that, we hypothesized, (i) inhibit the recovery of kelp forests on an urbanized coast, and (ii) form more extensive covers and greater biomass under moderate future CO2 and associated temperature increases. Our experimental removal of turfs from a phase-shifted system (i.e. kelp- to turf-dominated) revealed that the number of kelp recruits increased, thereby indicating that turfs can inhibit kelp recruitment. Future CO2 and temperature interacted synergistically to have a positive effect on the abundance of algal turfs, whereby they had twice the biomass and occupied over four times more available space than under current conditions. We suggest that the current preoccupation with the negative effects of ocean acidification on marine calcifiers overlooks potentially profound effects of increasing CO2 and temperature on non-calcifying organisms.

Ocean acidification affects growth but not nutritional quality of the seaweed Fucus vesiculosus (Phaeophyceae, Fucales)

Understanding the ecological implications of global climate change requires investigations of not only the direct effects of environmental change on species performance but also indirect effects that arise from altered species interactions. We performed CO2 perturbation experiments to investigate the effects of ocean acidification on the trophic interaction between the brown seaweed Fucus vesiculosus and the herbivorous isopod Idotea baltica. We predicted faster growth of F. vesiculosus at elevated CO2-concentrations and higher carbon content of the algal tissue. We expected that I. baltica has different consumption rates on algae that have been grown at different CO2 levels and that the isopods remove surplus carbon metabolically by enhanced respiration. Surprisingly, growth of F. vesiculosus as well as the C:N-ratio of the algal tissue were reduced at high CO2-levels. The changes in the elemental composition had no effect on the consumption rates and the respiration of the herbivores. An additional experiment showed that consumption of F. vesiculosus by the isopod Idotea emarginata was independent of ocean acidification and temperature. Our results could not reveal any effects of ocean acidification on the per capita strength of the trophic interaction between F. vesiculosus and its consumers. However, reduced growth of the algae at high CO2-concentrations might reduce the capability of the seaweed to compensate losses due to intense herbivory.

Interactions among chronic and acute impacts on coral recruits: the importance of size-escape thresholds

Newly settled recruits typically suffer high mortality from disturbances, but rapid growth reduces their mortality once size-escape thresholds are attained. Ocean acidification (OA) reduces the growth of recruiting benthic invertebrates, yet no direct effects on survivorship have been demonstrated. We tested whether the reduced growth of coral recruits caused by OA would increase their mortality by prolonging their vulnerability to an acute disturbance: fish herbivory on surrounding algal turf. After two months' growth in ambient or elevated CO2 levels, the linear extension and calcification of coral (Acropora millepora) recruits decreased as CO2 partial pressure (pCO2) increased. When recruits were subjected to incidental fish grazing, their mortality was inversely size dependent. However, we also found an additive effect of pCO2 such that recruit mortality was higher under elevated pCO2 irrespective of size. Compared to ambient conditions, coral recruits needed to double their size at the highest pCO2 to escape incidental grazing mortality. This general trend was observed with three groups of predators (blenny, surgeonfish, and parrotfish), although the magnitude of the fish treatment varied among species. Our study demonstrates the importance of size-escape thresholds in early recruit survival and how OA can shift these thresholds, potentially intensifying population bottlenecks in benthic invertebrate recruitment.

Environmental analyses of cyclic Middle Eocene sediments and palynomorph records of ODP Hole 189-1172A

The influence of orbital precession on early Paleogene climate and ocean circulation patterns in the southeast Pacific region is investigated by combining environmental analyses of cyclic Middle Eocene sediments and palynomorph records recovered from ODP Hole 1172A on the East Tasman Plateau with climate model simulations. Integration of results indicates that in the marine realm, direct effects of precessional forcing are not pronounced, although increased precipitation/runoff could have enhanced dinoflagellate cyst production. On the southeast Australian continent, the most pronounced effects of precessional forcing were fluctuations in summer precipitation and temperature on the Antarctic Margin. These fluctuations resulted in vegetational changes, most notably in the distribution of Nothofagus (subgenus Brassospora). The climate model results suggest significant fluctuations in sea ice in the Ross Sea, notably during Austral summers. This is consistent with the influx of Antarctic heterotrophic dinoflagellates in the early part of the studied record. The data demonstrate a strong precessionally driven climate variability and thus support the concept that precessional forcing could have played a role in early Antarctic glaciation via changes in runoff and/or precipitation.

Modelo multidimensional de los factores que afectan la interacción entre marketing y ventas en el lanzamiento de nuevos productos en Latino América

Esta tesis se centra en la identificación y análisis de los factores que pueden favorecer o actuar como barreras del éxito de la implementación de la innovación y las relaciones entre sí, desde el enfoque de la interface marketing-ventas. El trabajo empírico se enmarca en el vacío de investigación existente en el campo del proceso de lanzamiento de nuevos productos en los mercados donde operan subsidiarias de empresas multinacionales de consumo masivo (FMCG). Las empresas FMCG son altamente dependientes de la innovación como proceso clave determinante del crecimiento competitivo de mediano y largo plazo. En un contexto de acortamiento del ciclo de vida de los productos, como resultado del desarrollo tecnológico y científico que impactan en el comportamiento de los consumidores, las empresas invierten un mayor nivel de recursos en el desarrollo de nuevos productos, reingeniería y programas de innovación (Mundra, Gulati y Gupta, 2013). Sin embargo, a pesar del aumento en la inversión, las tasas de éxito de la innovación reportadas son inferiores al 25% (Evanschitzky, Eisend, Calantone y Jiang, 2012). Aumentar las tasas de éxito de los proyectos de innovación es reconocida en la literatura como un elemento clave para la supervivencia y competitividad de las empresas, para ser superiores a su competencia y desarrollar nuevos modelos de negocios. A pesar de la existencia de estudios que intentan comprender el proceso de lanzamiento de nuevos productos, no se ha identificado un claro prototipo de gestión de la innovación (Gupta et al, 2007). Profundizando en los factores de éxito, los autores Keupp, Palmié y Gassman (2012) reconocen que la innovación exitosa no depende solamente de la estrategia de selección de los proyectos de innovación, sino también la forma en que los mismos son implementados (Klein and Sorra, 1996; Repenning, 2002; Keupp, Palmié y Gassmann, 2012). Al analizar la implementación de los proyectos de lanzamiento de nuevos productos al mercado, en empresas FMCG, dicho proceso es responsabilidad principalmente de las funciones de marketing y ventas a través de la comunicación con los consumidores y los clientes respectivamente (Ernst, Hoyer y Rubsaamen, 2010). Es decir que el éxito en la implementación de la innovación requiere la gestión efectiva de la relación inter-funcional entre marketing y ventas (Ernst, Hoyer y Rubsaamen, 2010; Hughes, Le Bon y Malshe, 2012). A pesar de la importancia de la integración entre marketing y ventas en la conceptualización e implementación de la innovación, este tema no ha sido estudiado en profundidad (Hughes, Le Bon y Malshe, 2012; Keupp, Palmié y Gassmann, 2012). En las empresas multinacionales, está demostrado que el desempeño de las subsidiarias determinan el éxito competitivo de la empresa a nivel global. El desafío de dichas subsidiarias es conjugar el desarrollo global de innovación y comunicación con las características locales de comportamiento del consumidor y el mercado. Por lo tanto, esta investigación empírica responde a la pregunta académica y de gestión acerca de cómo mejorar las tasas de éxito de lanzamiento de nuevos productos al mercado en subsidiarias de empresas de consumo masivo, desde la perspectiva de la relación entre marketing y ventas. En particular analiza cómo afectan la formalización de los procesos y los mecanismos de comunicación a la confianza interpersonal y a la efectividad de la interface marketing-ventas y dichos factores a su vez sobre la planificación integrada de la implementación de la innovación. La determinación de los factores o ítems que conforman cada uno de los constructos del proceso de ejecución de la innovación, se llevó a cabo a partir de una revisión exhaustiva del estado del arte de la literatura sobre las interfaces funcionales y el proceso de innovación. Posteriormente, los ítems seleccionados (más de 50 en total) fueron validados por referentes de marketing y ventas de Argentina y Uruguay a través de entrevistas en profundidad. A partir de los factores identificados se construyeron dos modelos teóricos: • (1) relativo a la influencia de las dimensiones de confianza interpersonal sobre la efectividad de las uniones inter-funcionales y como los mecanismos organizacionales, tales como la frecuencia y la calidad de la comunicación entre las áreas, afectan la confianza y la relación entre ellas; • (2) relativo a la dimensión planificación integrada de la implementación de la innovación, ya que durante el lanzamiento de nuevos productos al mercado, marketing y ventas utilizan procesos formales que facilitan la comunicación frecuente y efectiva, desarrollando confianza inter-personal que no solamente afecta la efectividad de su relación sino también el desarrollo de planes integrados entre ambas áreas. El estudio fue llevado a cabo en una empresa multinacional de consumo masivo que integra la lista Global 500 (Fortune, 2015), presente en todo el mundo con más de 25 marcas participantes en más de 15 categorías, implementando 150 proyectos de innovación en el último año. El grupo de subsidiarias en estudio fue reconocido a nivel mundial por su desempeño en crecimiento competitivo y su alta contribución al crecimiento total. El modelo analizado en esta tesis fue expandido al resto de América Latina, tratándose entonces de un caso ejemplar que representa una práctica de excelencia en la implementación de la innovación en subsidiarias de una empresa multinacional. La recolección de los datos fue llevado a cabo a través de un cuestionario estructurado y confidencial, enviado a la base de datos de todo el universo de directores y gerentes de marketing y ventas. El nivel de respuesta fue muy elevado (70%), logrando 152 casos válidos. El análisis de datos comprendió el análisis descriptivo de los mismos, estimación de fiabilidad y análisis factorial exploratorio a través del software SPSS v.20. El análisis factorial confirmatorio y el análisis de senderos para examinar las relaciones entre los factores se estudiaron mediante el software R (Package 2.15.1., R Core Team, 2012) (Fox, 2006). Finalmente se llevaron a cabo entrevistas en profundidad a gerentes de marketing y ventas de cada uno de los seis países con el fin de profundizar en los constructos y sus relaciones. Los resultados de los modelos demuestran que la frecuencia de comunicación impacta positivamente en la calidad de la misma, que a su vez afecta directamente la relación entre marketing y ventas. Adicionalmente, la calidad de la comunicación impacta sobre la confianza cognitiva, que a su vez se relaciona no solamente con la confianza afectiva sino también con la relación entre ambas áreas. Esto significa que para mejorar la implementación de la innovación, los gerentes deberían orientarse a reforzar la relación entre marketing y ventas facilitando la construcción de confianza interpersonal primero cognitiva y luego afectiva, incrementando la frecuencia de la comunicación que alimenta la calidad de la comunicación entre ambas áreas. A través del segundo modelo se demuestra que durante el lanzamiento de nuevos productos al mercado, marketing y ventas necesitan emplear procesos formales que faciliten la comunicación frecuente y efectiva. De esta forma se contrarresta el efecto negativo de la formalización sobre la planificación integrada entre ambas áreas. Adicionalmente, los gerentes de ambos departamentos deberían promover la construcción de confianza interpersonal, no solamente para mejorar la efectividad de la relación, sino también para desarrollar planes integrados de implementación de nuevos productos. Finalmente, se valida que la frecuencia de la comunicación, la confianza afectiva y la relación marketing-ventas, se relacionan positivamente con la planificación integrada en la implementación de la innovación. El estudio contribuye a la comprensión de los factores que las empresas pueden emplear para mejorar la relación inter-funcional entre marketing y ventas y la implementación de la innovación en empresas de consumo masivo. El aporte de esta investigación puede ser valorado de dos maneras, los aportes a la gestión y a la academia. Desde el punto de vista empresarial, provee a los líderes al frente de empresas de consumo masivo, del conocimiento sobre los factores que afectan la implementación de la innovación y en definitiva el éxito del negocio a mediano y largo plazo. Desde el punto de vista académico aporta al conocimiento del proceso de implementación de la innovación y en la efectividad de la interface marketing y ventas en un caso de buenas prácticas en el mercado de consumo masivo. A su vez incorpora por primera vez un estudio empírico en geografías emergentes capaces de recuperar el camino de crecimiento posterior a una profunda crisis económica a través de la exitosa implementación de la innovación en sus mercados. ABSTRACT This thesis is focused on the identification, analysis and relationship study of factors which may benefit or hinder the successful deployment of innovation, from a marketing-sales interface perspective. Considering the non-existent investigation dedicated to the study of new products launches into markets in which Fast Moving Consumer Goods (FMCG) companies’ subsidiaries operate, it is that this investigation has been carried out. FMCG companies rely on innovation as their key process for a competitive growth on a medium and long term basis. Nowadays, the life-cycle of products is getting shorter as a result of new technological and scientific development, having impact on consumer behavior, and therefore companies are forced to dedicating more resources to the development of new products, reengineering and innovation programs (Mundra, Gulati and Gupta, 2013). However, in spite of the investment increase, the innovation success rates have been reported to be lower than 25% (Evanschitzky, Eisend, Calantone y Jiang, 2012). Increasing success rates on innovation processes has been considered as a key element on the survival and competitiveness of companies, outperforming competitors and developing new business models. Despite new studies which try to comprehend the process of new products launch, a prototype of innovation management has not yet been identified (Gupta et al, 2007). Emphasizing on success factors, authors Keupp, Palmié and Gassman (2012) recognize that successful innovation does not solely depend on innovation processes’ selection strategy, but it is also based on the way in which these are implemented (Klein and Sorra, 1996; Repenning, 2002; Keupp, Palmié y Gassmann, 2012). While analyzing the implementation of projects for new products releases on massive consumption companies, the two departments in charge of taking this forward are marketing and sales, by focusing on communication strategies with consumers and clients respectively (Ernst, Hoyer y Rubsaamen, 2010). This means that having success on innovation implementation requires an effective management of inter-functional relationship among marketing and sales (Ernst, Hoyer y Rubsaamen, 2010; Hughes, Le Bon y Malshe, 2012). In spite of the importance on the integration between marketing and sales on the conceptualization and implementation of innovation, this subject has not been studied in depth (Hughes, Le Bon y Malshe, 2012; Keupp, Palmié y Gassmann, 2012). In multinational companies, previous research has confirmed that the performance of their subsidiaries determine the competitive success of the company on a global scale. The challenge of said subsidiaries is to conjugate the global innovation development and communication with the local consumer and market behavior. Therefore, this empirical study aims to respond to the academic and management question of how to improve the success rates of new product launches into MNE subsidiary’ markets, from a marketing-sales relationship perspective. Particularly, this investigation analyses how the formalization of products and communication mechanisms affect interpersonal trust and marketing-sales interface effectiveness and also on how these factors affect the overall planning of the implementation of innovation. The determination of which factors build the hypothesis of the innovation execution process was taken forward through an extensive research on the extant literature on functional interfaces and innovation processes. More than 50 items were selected which were in turn validated by marketing and sales referents on Uruguay and Argentina through in depth interviews. Based on the identified factors, two theoretical models were proposed: (1) Relative to the influence that interpersonal trust dimensions have on inter functional linkages effectiveness and how organizational mechanisms such as frequency and quality of communication between departments affect trust and their relationship. (2) Relative to the integrated planning and innovation implementation dimensions. Marketing and sales department use formal process thus allowing inter-personal trust, which affects positively their relationship and also enables the development of integrated planning between them. The study was performed within a massive consumption company which is part of the “Global 500” (Fortune, 2015), with subsidiaries all over the world and more than 25 participant brands in 15 categories, having implemented over 150 innovation projects in the year under study. The analyzed subsidiary group has been awarded worldwide for their performance in competitive growth and their high contribution to the total growth. The model being analyzed in this thesis was implemented throughout Latin America, representing a remarkable case of innovation implementation excellence for subsidiaries of multinational companies. Data recollection was carried out through a structured and confidential questionnaire, sent to the universe of marketing-sales directors and managers’ database available with a high level of responsiveness of 70%, resulting in 152 valid cases. Data exploration involved a descriptive analysis, followed by a reliability estimation and an exploratory factorial analysis carried out through SPSS v.20. Confirmatory factorial analysis and path analysis (to examine relations between the different study factors) were studied using “R” software (Package 2.15.1., R Core Team, 2012) (Fox, 2006). Finally, in depth interviews were carried out to several marketing and sales managers in each of the six countries so as to further confirm the hypothesis and their relations. The models results prove that communication frequency has a positive impact on the quality of the same, which in turn has direct effects on the marketing-sales relations. Additionally, communication quality has an impact on the cognitive trust, which also relates not only to affective trust, but also to the relation between both areas. This means that in order to improve the implementation of innovation, managers should strive to enforce marketing-sales relations, facilitating the interpersonal trust construction (firstly cognitive, followed by affective trust), increasing the communication frequency, and therefore nurturing the communication quality among both areas. Through the second model, the results confirm the importance of creating effective relationships between sales and marketing to facilitate planning integrated new product implementations. While formalized new product development processes provide opportunities for sales and marketing to communicate, this does not directly influence the planning of integrated new product implementations. By using these formal opportunities to communicate to create information quality, it is possible to improve sales and marketing’s ability to integrate information during the planning process. Further, communication quality creates inter-personal trust in the other party’s competences (cognitive-based trust), leading to affect-based trust. Affect-based inter-personal trust, not only to improve the overall effectiveness of the sales and marketing relationship, but also helps in planning integrated new product implementations. This study contributes to the understanding of factors which enterprises can use to improve the inter-functional relations between marketing and sales, and the implementation of innovation in FMCG companies. The contribution of this investigation can be measured in two ways: enrichment of management and contribution to the academic area. From a business perspective, it provides massive consumption businesses leaders with knowledge on which factors affect innovation implementation, which results on mid and long-term success for the company. From an academic point of view, it provides knowledge on a prototype of successful innovation implementation management based on the marketing-sales interface effectiveness through a case study in the FMCG consumption market. Last but not least, it incorporates for the first time an empiric study on emerging geographies capable of recovery post a deep economic crisis through successful innovation implementation on their markets.

Compatibilidad de Eretmocerus mundus Mercet (Hymenoptera: Aphelinidae) y Amblyseius swirskii Athias-Henriot (Acari: Phytoseiidae), importantes enemigos naturales de la mosca blanca Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) en cultivos hortícolas, con nuevas barreras físicas selectivas y modernos plaguicidas

Los programas de Gestión Integrada de Plagas (GIP) promueven el uso de estrategias de control que sean respetuosas con el medio ambiente, sin embargo el uso de insecticidas en los cultivos hortícolas sigue siendo necesario para el control de determinadas plagas, como es el caso de la mosca blanca Bemisia tabaci (Gennadius). Por ello, el objetivo de esta tesis es el estudio de la integración de las tres estrategias de control más empleadas hoy en día para el control de plagas: el control biológico, el físico y el químico. Una primera parte de este trabajo ha consistido en el estudio de los efectos letales y subletales de once insecticidas, aplicados a la dosis máxima de campo, sobre los enemigos naturales Eretmocerus mundus Mercet y Amblyseius swirskii Athias-Henriot, mediante ensayos de laboratorio y persistencia (laboratorio extendido). Para la evaluación de la toxicidad de los insecticidas sobre los estados de vida más protegidos de estos enemigos naturales, se trataron bajo la Torre de Potter las pupas de E. mundus y los huevos de A. swirskii. Además, se llevaron a cabo ensayos de contacto residual para determinar los efectos letales y subletales de estos insecticidas sobre el estado adulto de ambas especies de enemigos naturales. Para ello, los pesticidas se aplicaron sobre placas de cristal (laboratorio) o sobre plantas (laboratorio extendido: persistencia). Los resultados mostraron que los insecticidas flonicamida, flubendiamida, metaflumizona, metoxifenocida, spiromesifen y spirotetramat eran compatibles con el estado de pupa de E. mundus (OILB 1: Inocuos). Sin embargo, abamectina, deltametrina y emamectina fueron categorizadas como ligeramente tóxicas (OILB 2) al causar efectos deletéreos. Los dos pesticidas más tóxicos fueron spinosad y sulfoxaflor, los cuales redujeron significativamente la emergencia de las pupas tratadas (OILB 4: Tóxicos). Flonicamida, flubendiamida, metoxifenocida y spiromesifen fueron compatibles con el estado adulto de E. mundus (OILB 1: Inocuos). Abamectina, deltametrina, emamectina, metaflumizona y spiromesifen pueden ser recomendados para su uso en programas de GIP, si se usan los plazos de seguridad apropiados, de acuerdo con la persistencia de cada uno de estos insecticidas, antes de la liberación del enemigo natural. Al contrario, spinosad y sulfoxaflor no resultaron ser compatibles (OILB D: Persistentes), aunque la realización de ensayos adicionales es necesaria para ver los efectos de los mismos en campo. Todos los insecticidas estudiados, excepto el spirotetramat (OILB 2: Ligeramente tóxico), fueron selectivos para el estado de huevo de A. swirskii (OILB 1: Inocuos). Flonicamida, flubendiamida, metaflumizona, metoxifenocida, spiromesifen, spirotetramat y sulfoxaflor, fueron compatibles con el estado adulto de A. swirskii (OILB 1: Inocuos). Abamectina, deltametrina, emamectina y spinosad pueden ser recomendados para su uso en programas de GIP, si se usan los plazos de seguridad apropiados, de acuerdo con la persistencia de cada uno de estos insecticidas, antes de la liberación del enemigo natural. Entre las nuevas estrategias de la GIP, los plásticos y mallas fotoselectivas han demostrado ser una herramienta importante para el control de plagas y enfermedades en cultivos hortícolas protegidos. Por ello, en una segunda parte de este trabajo, se estudiaron tanto los efectos directos, como la combinación de efectos directos y mediados por planta y plaga de ambientes pobres en luz UV, en presencia o ausencia del Virus del rizado amarillo del tomate (TYLCV), sobre E. mundus. En primer lugar, se realizó un ensayo al aire libre para la evaluación de la capacidad de vuelo de E. mundus en cajas tipo túnel (1 x 0,6 x 0,6 m) cubiertas con distintas barreras absorbentes de luz UV. Se detectó un efecto directo en la capacidad de orientación de E. mundus, debido a que este parasitoide utiliza estímulos visuales para localizar a sus huéspedes, únicamente en las barreras que bloqueaban más del 65% de la luz UV (malla G). En segundo lugar, bajo condiciones de invernadero, se evaluó la combinación de efectos directos y mediados por planta y plaga sobre E. mundus, usando plantas de tomate sanas o infectadas con el TYLCV y cajas (30 x 30 x 60 cm) cubiertas con los distintos plásticos fotoselectivos. En este caso, no se observó ningún efecto en la capacidad benéfica del parasitoide cuando este estaba en contacto con plantas de tomate infestadas con ninfas de B. tabaci, lo que demuestra que este insecto usa estímulos táctiles para encontrar a sus huéspedes a cortas distancias. Además, las diferentes condiciones de radiación UV estudiadas tuvieron cierto impacto en la morfología, fisiología y bioquímica de las plantas de tomate, infestadas o no con el virus de la cuchara, detectándose pequeñas alteraciones en alguno de los parámetros estudiados, como el peso fresco y seco, el contenido en H y el espesor de las cutículas y de las paredes celulares de la epidermis foliar. Por último, no se observaron efectos de la radiación UV mediados por planta, ni en B. tabaci ni en su parasitoide, E. mundus. En una tercera parte, se evaluaron los efectos de una malla tratada con bifentrin sobre ambos enemigos naturales, en ensayos de laboratorio, semicampo y campo. Las mallas tratadas fueron diseñadas originariamente para el control de mosquitos vectores de la malaria, y actualmente se está trabajando para su uso en agricultura, como una nueva estrategia de control de plagas. En ensayos de laboratorio, cuando adultos de E. mundus y A. swirskii se expusieron por contacto durante 72 horas con la malla tratada (cajas de 6 cm diámetro), se registró una alta mortalidad. Sin embargo, en el ensayo de preferencia, estos enemigos naturales no fueron capaces de detectar la presencia de bifentrin y, en aquellos individuos forzados a atravesar la malla tratada, no se observó mortalidad a corto plazo (72 horas). En estudios de semicampo, llevados a cabo bajo condiciones de invernadero en cajas de 25 x 25 x 60 cm de altura, la capacidad benéfica de E. mundus no se vio afectada. Finalmente, en ensayos de campo llevados a cabo en invernaderos comerciales (4000m2) en Almería, A. swirskii no se vio afectado por la presencia en el cultivo de la malla tratada con bifentrin y los niveles de infestación de B. tabaci y F. occidentalis detectados bajo dicha malla, fueron inferiores a los del control. Por último, se ha evaluado la composición de la microflora bacteriana de tres especies de parasitoides, E. mundus, Eretmocerus eremicus Rose & Zolnerowich y Encarsia formosa Gahan, y la influencia de la misma en su susceptibilidad a insecticidas. Se llevó a cabo una extracción total de ADN de los insectos y la región variable V4 del ARNr se amplificó usando cebadores universales bacterianos. Para identificar las secuencias de los géneros bacterianos presentes en los parasitoides, se realizó una Next Generation sequencing (Illumina sequencing). Una vez identificados los géneros bacterianos, el gen ADNr 16S de las Actinobacterias se amplificó del ADN extraído de los insectos, usando cebadores universales bacterianos y específicos de Actinobacterias, y los productos de la Nested PCR fueron clonados para identificar todas las especies del género Arthrobacter. Tres bacterias (A. aurescens Phillips, A. nicotinovarans Kodama, Yamamoto, Amano and Amichi y A. uratoxydans Stackebrandt, Fowler, Fiedler and Seiler), próximas a las especies de Arthrobacter presentes en los parasitoides, se obtuvieron de la colección bacteriana del BCCMTM/LMG y se midió su actividad esterasa. Finalmente, se realizaron ensayos con antibióticos (tetraciclina) y de contacto residual con insecticidas (abamectina) para determinar la influencia de las especies de Arthrobacter en la susceptibilidad de E. mundus a insecticidas. Los resultados muestran que este género bacteriano puede afectar a la toxicidad de E. mundus a abamectina, mostrando la importancia de la comunidad microbiana en enemigos naturales, factor que debe ser considerado en los estudios de evaluación de los riesgos de los insecticidas. ABSTRACT Integrated Pest Management (IPM) programs promote the use of control strategies more respectful with the environment; however the use of insecticides in vegetable crops is still needed to control certain pests, such as the whitefly Bemisia tabaci (Gennadius). Therefore, the objective of this work is to study the integration of the three most commonly used pest control strategies nowadays: biological, physical and chemical control. Firstly, the lethal and sublethal effects of eleven insecticides, applied at their maximum field recommended concentration, on the parasitic wasp Eretmocerus mundus Mercet and the predator Amblyseius swirskii Athias-Henriot has been assessed in the laboratory and in persistence tests (extended laboratory). To test the effects of pesticides on the most protected life stage of these natural enemies, E. mundus pupae and A. swirskii eggs were sprayed under a Potter precision spray tower. Laboratory contact tests were therefore conducted to determine the lethal and sublethal effects of these pesticides on the adult stage of these natural enemies. In the residual contact tests the pesticides were applied on glass plates (laboratory) or plants (extended laboratory: persistence). The study showed that the insecticides flonicamid, flubendiamide, metaflumizone, methoxyfenozide, spiromesifen and spirotetramat were selective for E. mundus pupae (IOBC 1: Harmless). Nevertheless, abamectin, deltamethrin and emamectin were categorized as slightly harmful (IOBC 2) due to the deleterious effects caused. The two most harmful pesticides were spinosad and sulfoxaflor, which significantly reduced the adult emergence from treated pupae (IOBC 4: Harmful). Flonicamid, flubendiamide, methoxyfenozide and spiromesifen were compatible with E. mundus adults (IOBC 1: Harmless). Base on the duration of the harmful activity, abamectin, deltamethrin, emamectin, metaflumizone and spirotetramat could be recommended for use in IPM programs if appropriate safety deadlines are used before the natural enemy release. On the contrary, spinosad and sulfoxaflor were not compatible (IOBC D: persistent), although additional studies are required to determine their effects under field conditions. All the pesticides tested, except spirotetramat (IOBC 2: Slightly harmful), were selective for A. swirskii eggs (IOBC 1: Harmless). Flonicamid, flubendiamide, metaflumizone, methoxyfenozide, spiromesifen, spirotetramat and sulfoxaflor were compatible with A. swirskii adults (IOBC 1: Harmless). However, abamectin, deltamethrin, emamectin and spinosad could be recommended for use in IPM programs if appropriate safety deadlines are used before the natural enemy release. Among new IPM strategies, UV-absorbing photoselective plastic films and nets have been shown to be an important tool for the control of pests and diseases in horticultural protected crops. Because of that, we secondly studied the plant and pest insect-mediated and/or the direct effects on E. mundus under different UV radiation conditions, in presence or absence of the Tomato Yellow Leaf Curl Virus (TYLCV). In the first experiment, performed outdoors, the flight activity of E. mundus was studied in one-chamber tunnels (1 x 0.6 x 0.6 m) covered with different photoselective barriers. Because E. mundus uses visual cues for host location at a long distance, a direct effect on its host location ability was detected, but only in the UV-absorbing barriers blocking more than 65% of the UV light (G net). In a second experiment, the direct and plant and pest insect-mediated effects of different UV radiation conditions on E. mundus were studied, inside cages (30 x 30 x 60 cm) covered with the different UVplastic films and under greenhouse conditions, using healthy or TYLCV-virus infected tomato plants. In this case, not any effect on the beneficial capacity of this parasitoid was detected, proving that he uses tactile cues at a short distance of the host. Moreover, the different UV radiation conditions studied had a certain direct impact in the morphology, physiology and biochemistry of tomato plants infested or not with the TYLCV, and small alterations in some parameters such as fresh and dry weight, H percentage and cuticle and cell wall thickness of epidermal cells of the leaves, were detected. Finally, none plant-mediated UV effects neither in the whitefly B. tabaci nor in their parasitic wasp were found. Thirdly, the effects of a bifenthrin treated net were evaluated in different laboratory, semi-field and field experiments on the natural enemies studied. Treated nets were developed long time ago aiming at the control of the mosquitoes vectors of malaria, and nowadays, there is a great interest on assessing the possibility of their use in agriculture. In laboratory assays, a high mortality was recorded when E. mundus and A. swirskii adults were exposed by contact to the bifenthrin treated net for 72 hours in small cages (12 cm diameter). However, these natural enemies were not able to detect the presence of bifenthrin in a dual-choice test and no short-term mortality (72 hours) was recorded in those individuals that went through the treated net. In semi-field assays, performed under greenhouse conditions with cages of 25 x 25 x 60 cm high, the beneficial capacity of E. mundus was not affected. Finally, in field assays carried out in commercial multispan greenhouses (4000 m2) in Almería, A. swirskii was not affected by the presence of the bifenthrin treated net in the crop and the B. tabaci and F. occidentalis infestation levels were significantly lower than in the control. Finally, the composition of the microflora present in three species of parasitoids, E. mundus, Eretmocerus eremicus Rose & Zolnerowich and Encarsia formosa Gahan, and its influence in their susceptibility to insecticides, have been assessed. A total DNA extraction was performed on insects and universal bacterial primers were used to amplify the variable V4 region of the rRNA. A Next Generation sequencing (Illumina sequencing) was performed to identify the sequences of the bacterial genera present in the parasitic wasps. Once, the bacterial genera were identified, 16S rDNA gene of Actinobacteria were amplified from insects DNA extracts using the universal bacterial and actinobacterial primers, and the nested PCR products, were cloned to identify the Arthrobacter species. Three bacteria (A. aurescens Phillips, A. nicotinovarans Kodama, Yamamoto, Amano and Amichi and A. uratoxydans Stackebrandt, Fowler, Fiedler and Seiler), having the closest match with the Arthrobacter species present in the parasitic wasps, were obtained from the BCCMTM/LMG bacteria collection and its esterase activity was measured. Finally, antibiotic and residual contact tests were done to determine the influence of Arthrobacter species in the susceptibility of E. mundus to pesticides (abamectin). The results suggest that this bacterial genus can affect the toxicity of E. mundus to abamectin, which in turn supports the importance of the microbial community in natural enemies that it should be considered as a factor in risk assessment tests of pesticides.
