Asset Management (AM) is a set of procedures operable at the strategic-tacticaloperational level, for the management of the physical asset’s performance, associated risks and costs within its whole life-cycle. AM combines the engineering, managerial and informatics points of view. In addition to internal drivers, AM is driven by the demands of customers (social pull) and regulators (environmental mandates and economic considerations). AM can follow either a top-down or a bottom-up approach. Considering rehabilitation planning at the bottom-up level, the main issue would be to rehabilitate the right pipe at the right time with the right technique. Finding the right pipe may be possible and practicable, but determining the timeliness of the rehabilitation and the choice of the techniques adopted to rehabilitate is a bit abstruse. It is a truism that rehabilitating an asset too early is unwise, just as doing it late may have entailed extra expenses en route, in addition to the cost of the exercise of rehabilitation per se. One is confronted with a typical ‘Hamlet-isque dilemma’ – ‘to repair or not to repair’; or put in another way, ‘to replace or not to replace’. The decision in this case is governed by three factors, not necessarily interrelated – quality of customer service, costs and budget in the life cycle of the asset in question. The goal of replacement planning is to find the juncture in the asset’s life cycle where the cost of replacement is balanced by the rising maintenance costs and the declining level of service. System maintenance aims at improving performance and maintaining the asset in good working condition for as long as possible. Effective planning is used to target maintenance activities to meet these goals and minimize costly exigencies. The main objective of this dissertation is to develop a process-model for asset replacement planning. The aim of the model is to determine the optimal pipe replacement year by comparing, temporally, the annual operating and maintenance costs of the existing asset and the annuity of the investment in a new equivalent pipe, at the best market price. It is proposed that risk cost provide an appropriate framework to decide the balance between investment for replacing or operational expenditures for maintaining an asset. The model describes a practical approach to estimate when an asset should be replaced. A comprehensive list of criteria to be considered is outlined, the main criteria being a visà- vis between maintenance and replacement expenditures. The costs to maintain the assets should be described by a cost function related to the asset type, the risks to the safety of people and property owing to declining condition of asset, and the predicted frequency of failures. The cost functions reflect the condition of the existing asset at the time the decision to maintain or replace is taken: age, level of deterioration, risk of failure. The process model is applied in the wastewater network of Oslo, the capital city of Norway, and uses available real-world information to forecast life-cycle costs of maintenance and rehabilitation strategies and support infrastructure management decisions. The case study provides an insight into the various definitions of ‘asset lifetime’ – service life, economic life and physical life. The results recommend that one common value for lifetime should not be applied to the all the pipelines in the stock for investment planning in the long-term period; rather it would be wiser to define different values for different cohorts of pipelines to reduce the uncertainties associated with generalisations for simplification. It is envisaged that more criteria the municipality is able to include, to estimate maintenance costs for the existing assets, the more precise will the estimation of the expected service life be. The ability to include social costs enables to compute the asset life, not only based on its physical characterisation, but also on the sensitivity of network areas to social impact of failures. The type of economic analysis is very sensitive to model parameters that are difficult to determine accurately. The main value of this approach is the effort to demonstrate that it is possible to include, in decision-making, factors as the cost of the risk associated with a decline in level of performance, the level of this deterioration and the asset’s depreciation rate, without looking at age as the sole criterion for making decisions regarding replacements.

In the southern part of Korup National Park, Cameroon, the mast fruiting tree Microberlinia bisulcata occurs as a codominant in groves of ectomycorrhizal Caesalpiniaceae within a mosaic of otherwise species-rich lowland rain forest. To estimate the amount of carbon and nutrients invested in reproduction during a mast fruiting event, and the consequential seed and seedling survival, three related field studies were made in 1995. These provided a complete seed and seedling budget for the cohort. Seed production was estimated by counting woody pods on the forest floor. Trees produced on average 26,000 (range 0-92,000) seeds/tree, with a dry mass of 16.6 kg/tree. Seeds were contained in woody pods of mass 307 kg/tree. Dry mass production of pods and seeds was 1034 kg ha(-1), equivalent to over half (55%) of annual leaf litterfall for this species, and contained 13% of the nitrogen and 21% of the phosphorus in annual leaf litterfall. Seed and young-seedling mortality was investigated with open quadrats and cages to exclude vertebrate predators, at two distances from the parent tree. The proportion of seeds on the forest floor which disappeared in the first 6 wk after dispersal was 84%, of which 26.5% was due to likely vertebrate removal, 36% to rotting, and 21.5% to other causes. Vertebrate predation was greater close to the stem than 5 m beyond the crown (41 vs 12% of seeds disappearing) where the seed shadow was less dense. Previous studies have demonstrated an association between mast years at Korup and high dry-season radiation before flowering, and have shown lower leaf-litterfall phosphorus concentrations following mast fruiting. The emerging hypothesis is that mast fruiting is primarily imposed by energy limitation for fruit production, but phosphorus supply and vertebrate predation are regulating factors. Recording the survival of naturally-regenerating M. bisulcata seedlings (6-wk stage) showed that 21% of seedlings survived to 31 mo. A simple three-stage recruitment model was constructed. Mortality rates were initially high and peaked again in each of the next two dry seasons, with smaller peaks in the two intervening wet seasons, these latter coinciding with annual troughs in radiation. The very poor recruitment of M. bisulcata trees in Korup, demonstrated in previous investigations, appears not to be due to a limitation in seed or young-seedling supply, but rather by factors operating at the established-seedling stage.

Paper I: Corporate aging and internal resource allocation Abstract Various observers argue that established firms are at a disadvantage in pursuing new growth opportunities. In this paper, we provide systematic evidence that established firms allocate fewer resources to high-growth lines of business. However, we find no evidence of inefficient resource allocation in established firms. Redirecting resources from high-growth to low-growth lines of business does not result in lower profitability. Also, resource allocation towards new growth opportunities does not increase when managers of established firms are exposed to takeover and product market threats. Rather, it seems that conservative resource allocation strategies are driven by pressures to meet investors’ expectations. Our empirical evidence, thus, favors the hypothesis that established firms wisely choose to allocate fewer resources to new growth opportunities as external pressures force them to focus on efficiency rather than novelty (Holmström 1989). Paper II: Corporate aging and asset sales Abstract This paper asks whether divestitures are motivated by strategic considerations about the scope of the firm’s activities. Limited managerial capacity implies that exploiting core competences becomes comparatively more attractive than exploring new growth opportunities as firms mature. Divestitures help stablished firms free management time and increase the focus on core competences. The testable implication of this attention hypothesis is that established firms are the main sellers of assets, that their divestiture activity increases when managerial capacity is scarcer, that they sell non-core activities, and that they return the divestiture proceeds to the providers of capital instead of reinvesting them in the firm. We find strong empirical support for these predictions. Paper III: Corporate aging and lobbying expenditures Abstract Creative destruction forces constantly challenge established firms, especially in competitive markets. This paper asks whether corporate lobbying is a competitive weapon of established firms to counteract the decline in rents over time. We find a statistically and economically significant positive relation between firm age and lobbying expenditures. Moreover, the documented age-effect is weaker when firms have unique products or operate in concentrated product markets. To address endogeneity, we use industry distress as an exogenous nonlegislative shock to future rents and show that established firms are relatively more likely to lobby when in distress. Finally, we provide empirical evidence that corporate lobbying efforts by established firms forestall the creative destruction process. In sum, our findings suggest that corporate lobbying is a competitive weapon of established firms to retain profitability in competitive environments.

We compared lifetime and population energy budgets of the extraordinary long-lived ocean quahog Arctica islandica from 6 different sites - the Norwegian coast, Kattegat, Kiel Bay, White Sea, German Bight, and off northeast Iceland - covering a temperature and salinity gradient of 4-10°C (annual mean) and 25-34, respectively. Based on von Bertalanffy growth models and size-mass relationships, we computed organic matter production of body (PSB) and of shell (PSS), whereas gonad production (PG) was estimated from the seasonal cycle in mass. Respiration (R) was computed by a model driven by body mass, temperature, and site. A. islandica populations differed distinctly in maximum life span (40 y in Kiel Bay to 197 y in Iceland), but less in growth performance (phi' ranged from 2.41 in the White Sea to 2.65 in Kattegat). Individual lifetime energy throughput, as approximated by assimilation, was highest in Iceland (43,730 kJ) and lowest in the White Sea (313 kJ). Net growth efficiency ranged between 0.251 and 0.348, whereas lifetime energy investment distinctly shifted from somatic to gonad production with increasing life span; PS/PG decreased from 0.362 (Kiel Bay, 40 y) to 0.031 (Iceland, 197 y). Population annual energy budgets were derived from individual budgets and estimates of population mortality rate (0.035/y in Iceland to 0.173/y in Kiel Bay). Relationships between budget ratios were similar on the population level, albeit with more emphasis on somatic production; PS/ PG ranged from 0.196 (Iceland) to 2.728 (White Sea), and P/B ranged from 0.203-0.285/y. Life span is the principal determinant of the relationship between budget parameters, whereas temperature affects net growth efficiency only. In the White Sea population, both growth performance and net growth efficiency of A. islandica were lowest. We presume that low temperature combined with low salinity represent a particularly stressful environment for this species.

This paper reviews the relationship between public sector investment and private sector investment through government expenditures financed by government bonds in the Japanese economy. This study hypothesizes that deficit financing by bond issues does not crowd out private sector investment, and this finance method may crowd in. Thus the government increases bond issues and sells them in the domestic and international financial markets. This method does not affect interest rates because they are insensitive to government expenditures and they depend on interest rates levels in the international financial market more than in the domestic financial market because of globalization and integration among financial markets.

La competitividad del transporte de mercancías depende del estado y funcionamiento de las redes existentes y de sus infraestructuras, no del modo de transporte. En concreto, la rentabilidad o la reducción de los costes de producción del transporte marítimo se vería incrementado con el uso de buques de mayor capacidad y con el desarrollo de plataformas portuarias de distribución o puertos secos, ya que el 90% del comercio entre la Unión Europea y terceros países se realiza a través de sus puertos a un promedio de 3,2 billones de toneladas de mercancías manipuladas cada año y el 40% del tráfico intraeuropeo utiliza el transporte marítimo de corta distancia. A pesar de que los puertos europeos acogen anualmente a más de 400 millones de pasajeros, los grandes desarrollos se han producido en los puertos del norte de Europa (Róterdam, Amberes, Ámsterdam). Los países del Sur de Europa deben buscar nuevas fórmulas para ser más competitivos, ya sea mediante creación de nuevas infraestructuras o mediante refuerzo de las existentes, ofreciendo los costes de los puertos del Norte. El fomento del transporte marítimo y fluvial como alternativa al transporte por carretera, especialmente el transporte marítimo de corta distancia, ha sido impulsado por la Comisión Europea (CE) desde 2003 a través de programas de apoyo comunitario de aplicación directa a las Autopistas del Mar, a modo de ejemplo, cabría citar los programas Marco Polo I y II, los cuales contaron con una dotación presupuestaria total de 855 millones de euros para el período 2003 – 2013; en ese período de tiempo se establecieron objetivos de reducción de congestión vial y mejora del comportamiento medio ambiental del sistema de transporte de mercancías dentro de la comunidad y la potenciación de la intermodalidad. El concepto de Autopista del Mar surge en el Libro Blanco de Transportes de la Comisión Europea “La política europea de transportes de cara al 2010: La hora de la verdad” del 12 de diciembre de 2001, en el marco de una política europea para fomento y desarrollo de sistemas de transportes sostenibles. Las Autopistas del Mar consisten en rutas marítimas de corta distancia entre dos puntos, de menor distancia que por vía terrestre, en las que a través del transporte intermodal mejoran significativamente los tiempos y costes de la cadena logística, contribuyen a la reducción de accidentes, ruidos y emisiones de CO2 a la atmósfera, permite que los conductores pierdan horas de trabajo al volante y evita el deterioro de las infraestructuras terrestres, con el consiguiente ahorro en mantenimiento. La viabilidad de una Autopista del Mar depende tanto de factores de ubicación geográficos, como de características propias del puerto, pasando por los diferentes requerimientos del mercado en cada momento (energéticos, medio ambientales y tecnológicos). Existe un elemento nuevo creado por la Comisión Europea: la red transeuropea de transportes (RTE-T). En el caso de España, con sus dos accesos por los Pirineos (La Junquera e Irún) como únicos pasos terrestres de comunicación con el continente y con importantes limitaciones ferroviarias debido a los tres anchos de vía distintos, le resta competitividad frente al conjunto europeo; por el contrario, España es el país europeo con más kilómetros de costa (con más de 8.000 km) y con un emplazamiento geográfico estratégico, lo que le convierte en una plataforma logística para todo el sur de Europa, por lo que las Autopistas del Mar tendrán un papel importante y casi obligado para el desarrollo de los grandes corredores marítimos que promueve Europa. De hecho, Gijón y Vigo lo han hecho muy bien con sus respectivas líneas definidas como Autopistas del Mar y que conectan con el puerto francés de Nantes-Saint Nazaire, ya que desde ahí los camiones pueden coger rutas hacia el Norte. Paralelamente, la Unión Europea ha iniciado los pasos para el impulso de la primera Autopista del Mar que conectará España con el mercado de Reino Unido, concretamente los Puertos de Bilbao y Tilbury. Además, España e Italia sellaron un acuerdo internacional para desarrollar Autopistas del Mar entre ambos países, comprometiéndose a impulsar una docena de rutas entre puertos del litoral mediterráneo español y el italiano. Actualmente, están en funcionando los trayectos como Barcelona-Génova, Valencia-Civitavecchia y Alicante- Nápoles, notablemente más cortos por mar que por carretera. Bruselas identificó cuatro grandes corredores marítimos que podrían concentrar una alta densidad de tráfico de buques, y en dos de ellos España ya tenía desde un principio un papel crucial. La Comisión diseñó el 14 de abril de 2004, a través del proyecto West-Mos, una red de tráfico marítimo que tiene como vías fundamentales la denominada Autopista del Báltico (que enlaza Europa central y occidental con los países bálticos), la Autopista de Europa suroriental (que une el Adriático con el Jónico y el Mediterráneo más oriental) y también la Autopista de Europa occidental y la Autopista de Europa suroccidental (que enlazan España con Reino Unido y la Francia atlántica y con la Francia mediterránea e Italia, respectivamente). Para poder establecer Autopistas del Mar entre la Península Ibérica y el Norte de Europa primará especialmente la retirada de camiones en la frontera pirenaica, donde el tráfico pesado tiene actualmente una intensidad media diaria de 8.000 unidades, actuando sobre los puntos de mayor congestión, como por ejemplo los Alpes, los Pirineos, el Canal de la Mancha, las carreteras fronterizas de Francia y Euskadi, y proponiendo el traslado de las mercancías en barcos o en trenes. Por su parte, para contar con los subsidios y apoyos europeos las rutas seleccionadas como Autopistas del Mar deben mantener una serie de criterios de calidad relacionados con la frecuencia, coste “plataforma logística a plataforma logística”, simplicidad en procedimientos administrativos y participación de varios países, entre otros. Los estudios consideran inicialmente viables los tramos marítimos superiores a 450 millas, con un volumen de unas 15.000 plataformas al año y que dispongan de eficientes comunicaciones desde el puerto a las redes transeuropeas de autopistas y ferrocarril. Otro objetivo de las Autopistas del Mar es desarrollar las capacidades portuarias de forma que se puedan conectar mejor las regiones periféricas a escala del continente europeo. En lo que a Puertos se refiere, las terminales en los muelles deben contar con una línea de atraque de 250 m., un calado superior a 8 m., una rampa “ro-ro” de doble calzada, grúas portainer, y garantizar operatividad para un mínimo de dos frecuencias de carga semanales. El 28 de marzo de 2011 se publicó el segundo Libro Blanco sobre el futuro del transporte en Europa “Hoja de ruta hacia un espacio único europeo de transporte: por una política de transportes competitiva y sostenible”, donde se definió el marco general de las acciones a emprender en los próximos diez años en el ámbito de las infraestructuras de transporte, la legislación del mercado interior, la reducción de la dependencia del carbono, la tecnología para la gestión del tráfico y los vehículos limpios, así como la estandarización de los distintos mercados. Entre los principales desafíos se encuentran la eliminación de los cuellos de botella y obstáculos diversos de nuestra red europea de transporte, minimizar la dependencia del petróleo, reducir las emisiones de GEI en un 60% para 2050 con respecto a los niveles de 1990 y la inversión en nuevas tecnologías e infraestructuras que reduzcan estas emisiones de transporte en la UE. La conexión entre la UE y el norte de África provoca elevados niveles de congestión en los puntos más críticos del trayecto: frontera hispano-francesa, corredor del Mediterráneo y el paso del estrecho. A esto se le añade el hecho de que el sector del transporte por carretera está sujeto a una creciente competencia de mercado motivada por la eliminación de las barreras europeas, mayores exigencias de los cargadores, mayores restricciones a los conductores y aumento del precio del gasóleo. Por otro lado, el mercado potencial de pasajeros tiene una clara diferenciación en tipos de flujos: los flujos en el período extraordinario de la Operación Paso del Estrecho (OPE), enfocado principalmente a marroquíes que vuelven a su país de vacaciones; y los flujos en el período ordinario, enfocado a la movilidad global de la población. Por tanto, lo que se pretende conseguir con este estudio es analizar la situación actual del tráfico de mercancías y pasajeros con origen o destino la península ibérica y sus causas, así como la investigación de las ventajas de la creación de una conexión marítima (Autopista del Mar) con el Norte de África, basándose en los condicionantes técnicos, administrativos, económicos, políticos, sociales y medio ambientales. The competitiveness of freight transport depends on the condition and operation of existing networks and infrastructure, not the mode of transport. In particular, profitability could be increased or production costs of maritime transport could be reduced by using vessels with greater capacity and developing port distribution platforms or dry ports, seeing as 90% of trade between the European Union and third countries happens through its ports. On average 3,2 billion tonnes of freight are handled annualy and 40% of intra-European traffic uses Short Sea Shipping. In spite of European ports annually hosting more than 400 million passengers, there have been major developments in the northern European ports (Rotterdam, Antwerp, Amsterdam). Southern European countries need to find new ways to be more competitive, either by building new infrastructure or by strengthening existing infrastructure, offering costs northern ports. The use of maritime and river transport as an alternative to road transport, especially Short Sea Shipping, has been driven by the European Commission (EC) from 2003 through community support programs for the Motorways of the Sea. These programs include, for example, the Marco Polo I and II programs, which had a total budget of 855 million euros for the period 2003-2013. During this time objectives were set for reducing road congestion, improving the environmental performance of the freight transport system within the community and enhancing intermodal transport. The “Motorway of the Sea” concept arises in the European Commission’s Transport White Paper "European transport policy for 2010: time to decide" on 12 December 2001, as part of a European policy for the development and promotion of sustainable transport systems. A Motorway of the Sea is defined as a short sea route between two points, covering less distance than by road, which provides a significant improvement in intermodal transport times and to the cost supply chain. It contributes to reducing accidents, noise and CO2 emissions, allows drivers to shorten their driving time and prevents the deterioration of land infrastructure thereby saving on maintenance costs. The viability of a Motorway of the Sea depends as much on geographical location factors as on characteristics of the port, taking into account the different market requirements at all times (energy, environmental and technological). There is a new element created by the European Commission: the trans-European transport network (TEN-T). In the case of Spain, with its two access points in the Pyrenees (La Junquera and Irun) as the only land crossings connected to the mainland and major railway limitations due to the three different gauges, it appears less competitive compared to Europe as a whole. However, Spain is the European country with the most kilometers of coastline (over 8,000 km) and a strategic geographical location, which makes it a logistics platform for the all of Southern Europe. This is why the Motorways of the Sea will have an important role, and an almost necessary one to develop major maritime corridors that Europe supports. In fact, Gijon and Vigo have done very well with their respective sea lanes defined as Motorways of the Sea and which connect with the French port of Nantes-Saint Nazaire, as from there trucks can use nort-heading routes. In parallel, the European Union has taken the first steps to boost the first Motorway of the Sea linking Spain to the UK market, specifically the ports of Bilbao and Tilbury. Furthermore, Spain and Italy sealed an international agreement to develop Motorways of the Sea between both countries, pledging to develop a dozen routes between ports on the Spanish and Italian Mediterranean coasts. Currently, there are sea lanes already in use such as Barcelona-Genova, Valencia-Civitavecchia and Alicante-Naples, these are significantly shorter routes by sea than by road. Brussels identified four major maritime corridors that could hold heavy concentrate shipping traffic, and Spain had a crucial role in two of these from the beginning. On 14 April 2004 the Commission planned through the West-Mos project, a network of maritime traffic which includes the essential sea passages the so-called Baltic Motorway (linking Central and Western Europe with the Baltic countries), the southeast Europe Motorway (linking the Adriatic to the Ionian and eastern Mediterranean Sea), the Western Europe Motorway and southwestern Europe Motorway (that links Spain with Britain and the Atlantic coast of France and with the French Mediterranean coast and Italy, respectively). In order to establish Motorways of the Sea between the Iberian Peninsula and Northern Europe especially, it is necessary to remove trucks from the Pyrenean border, where sees heavy traffic (on average 8000 trucks per day) and addressing the points of greatest congestion, such as the Alps, the Pyrenees, the English Channel, the border roads of France and Euskadi, and proposing the transfer of freight on ships or trains. For its part, in order to receive subsidies and support from the European Commission, the routes selected as Motorways of the Sea should maintain a series of quality criteria related to frequency, costs "from logistics platform to logistics platform," simplicity in administrative procedures and participation of several countries, among others. To begin with, studies consider viable a maritime stretch of at least 450 miles with a volume of about 15,000 platforms per year and that have efficient connections from port to trans-European motorways and rail networks. Another objective of the Motorways of the Sea is to develop port capacity so that they can better connect peripheral regions across the European continent. Referring ports, the terminals at the docks must have a berthing line of 250 m., a draft greater than 8 m, a dual carriageway "ro-ro" ramp, portainer cranes, and ensure operability for a minimum of two loads per week. On 28 March 2011 the second White Paper about the future of transport in Europe "Roadmap to a Single European Transport Area – Towards a competitive and resource efficient transport system" was published. In this Paper the general framework of actions to be undertaken in the next ten years in the field of transport infrastructure was defined, including internal market legislation, reduction of carbon dependency, traffic management technology and clean vehicles, as well as the standardization of different markets. The main challenges are how to eliminate bottlenecks and various obstacles in our European transport network, minimize dependence on oil, reduce GHG emissions by 60% by 2050 compared to 1990 levels and encourage investment in new technologies and infrastructure that reduce EU transport emissions. The connection between the EU and North Africa causes high levels of congestion on the most critical points of the journey: the Spanish-French border, the Mediterranean corridor and Gibraltar Strait. In addition to this, the road transport sector is subject to increased market competition motivated by the elimination of European barriers, greater demands of shippers, greater restrictions on drivers and an increase in the price of diesel. On the other hand, the potential passenger market has a clear differentiation in type of flows: flows in the special period of the Crossing the Straits Operation (CSO), mainly focused on Moroccans who return home on vacation; and flows in the regular session, focused on the global mobile population. Therefore, what I want to achieve with this study is present an analysis of the current situation of freight and passengers to or from the Iberian Peninsula and their causes, as well as present research on the advantages of creating a maritime connection (Motorways of the Sea) with North Africa, based on the technical, administrative, economic, political, social and environmental conditions.

Offering competitive health and wellness benefit programs is ever challenging for companies, as industry leaders continually devise ways to innovate and deliver high-value programs to attract and retain employees. Financial stability is a form of wellness, and yet companies offer limited finance-related benefit offerings. Employees are commonly given access to retirement savings plans and college savings plans, and yet employers do not typically incorporate educational components into benefit programs. Research presented in this paper examines the financial issues impacting the lives of young workers in the United States and makes the case for a new recruitment and retention tool: a dynamic, practical benefit program designed to engage employees in their financial planning early and empower them to make informed decisions.
