The role of the tourism sector in economic development. Lessons from the Spanish experience

Tourism is one of the most important sectors in the global economy and is considered an efficient tool with which to promote economic growth. The case of Spain¿s economy is well known in this respect; in fact, widespread consensus exists on the part played by tourism in enhancing the industrialisation process in Spain and the part played by foreign currency receipts from tourism in financing the imports of capital goods, which made the expansion of manufacturing possible. This paper aims to assess the real role of foreign currency receipts from tourism in Spain¿s economy from 1960 to the present. The results of Spain¿s experience may well help to guide policy decisions in developing countries in similar circumstances.

The First Privatization Policy in a Democracy: Selling State-Owned Enterprises in 1948-1950, Puerto Rico

In the 1940s, when the Governor of Puerto Rico was appointed by the US President and the Puerto Rican government was answerable only to the US Federal government, a large state-owned enterprise (SOE) sector was established on the island. Public services such as water, transportation and energy were nationalized, and several new manufacturing SOEs were created to produce cement, glass, shoes, paper and chalkboard, and clay products. These enterprises were created and managed by government-owned corporations. Later on, between 1948 and 1950, under the island’s first elected Governor, the government sold these SOEs to private groups. This paper documents both the creation and the privatization of the SOE sector in Puerto Rico, and analyzes the role played by ideology, political interests, and economic concerns in the decision to privatize them. Whereas ideological factors might have played a significant role in the building of the SOE sector, we find that privatization was driven basically by economic factors, such as the superior efficiency of private firms in the sectors where the SOEs operated, and by the desire to attract private industrial investment to the Puerto Rican economy.

Catalytic Wet Oxidation of Paper Mill Debarking Water

The objective of the research was to study the influence of temperature, oxygen pressure, catalysts loading and initial COD concentration of debarking wastewater on the pollutants during the catalytic oxidation. More importantly, how the addition of catalyst affects the wet oxidation process. The whole work was divided into two main sections, theoretical and experimental parts. The theoretical part reviews the pulp and paper industry from wood processing to paper production as well as operations that generate wastes. Treatment methods applicable for industrial pulp and paper mill effluents were also discussed. Wet oxidation and catalytic wet oxidation processes including mechanism, reactions, kinetics and industrial applications were previewed. In the experimental part, catalytic wet oxidation process were studied at 120-180°C, 0-10 bar oxygen pressure, 0-1 g/L catalyst concentration and 1000-3000 mg/L initial COD concentration. Responses, such as Chemical oxygen demand (COD), Total organic carbon (TOC), colour, lignin/tannin, Biochemical oxygen demand (BOD) and pH were measured. In the experiment, the best conditions occurred at 180°C, 10 bar, l g/L catalyst concentration and 3000mg/L initial COD. At these conditions; 74% COD, 97% lignin/tannin, 54% TOC, 90% colour were removed from the wastewater. pH was greatly reduced from 7 to 4.6. Lignin/tannin was removed most. Lignin/tannin showed linear dependency with colour during oxidation. Temperature made the most impact in reducing contaminants in debarked wastewater.

Technology roadmap for new sales support and management system for crane manufacturing company

Sales configurators are essential tools for companies that offer complicated case specifically crafted products for customers. Most sophisticated of them are able to design an entire end product on the fly according to given constraints, calculate price for the offer and move the order into production. This thesis covers a sales configurator acquisition project in a large industrial company that offers cranes for its customers. The study spans the preliminary stages of a large-scale software purchase project starting from the specification of problem domain and ending up presenting the most viable software solution that fulfils the requirements for the new system. The project consists of mapping usage environment, use cases, and collecting requirements that are expected from the new system. The collected requirements involve fitting the new sales system into enterprise application infrastructure, mitigating the risks involved in the project and specifying new features to the application whilst preserving all of the admired features of the old sales system currently used in the company. The collected requirements were presented to a number of different sales software vendors who were asked to provide solution suggestions that would fulfil all the demands. All of the received solution proposals were exposed to an evaluation to determine the most feasible solutions, and the construction of evaluation criteria itself was a part of the study. The final outcome of this study is a short-list of the most feasible sales configurator solutions together with a description of how software purchase process in large enterprises work, and which aspects should be paid attention in large projects of similar kind.

Arqueometria ceràmica: una arqueologia ceràmica amb més informació

[spa] En el presente artículo se presentan los tres grandes ámbitos en los que se desarrolla la investigación arqueométrica sobre cerámicas: la identificación de los materiales, la proveniencia de los artefactos y la tecnología en la que se inscriben. El artículo hace una incidencia especial en aquello que se entiende por tecnología, indicando que la tecnología de producción es únicamente una parte de la misma, y que el concepto básico es el de diseño, que debe adecuarse a una multiplicidad de características de desempeño, explicadas por la cadena conductual en la cual transcurre la vida de los artefactos. Dado que las culturas se expresan por medio de artefactos, la vertiente material de éstos refleja, aunque sólo sea en parte, los compromisos que dichos artefactos tienen en las culturas en estudio. La arqueometría, con un cuerpo teórico y metodológico adaptado a la investigación de esta vertiente natural de los artefactos, aparece así como una forma complementaria de hacer arqueología y no como un campo de estudio diferenciado.

Productivity of Business Services - Towards A New Taxonomy

Statistics show that the expanding service sector accounts already for three quarters of GDP in the developed economies. Moreover, there is abundant evidence on high variation in productive performance across the service industries. This suggests divergent technological and institutional trajectories within the tertiary sector. While conceptual knowledge on services and their performance has accumulated substantially, the overall landscape on productivity and competitiveness is still inconclusive. As noted by number of authors the research on service productivity is still in its infancy. The purpose of this paper is to develop further the analytical framework of service productivity. The approach is based on the notion that service definitions, classifications and performance measurement are strongly interdependent. Given the ongoing restructuring of businesses activities with higher information content, it is argued that the dichotomy between manufacturing and services should not be taken too far. Industrial evolution also suggests that the official industry classifications are increasingly outdated and new taxonomies for empirical research are therefore needed. Based on the previous analyses and new insights the paper clarifies the debated concept of service productivity and identifies the critical dimensions by which the service industries cluster. It is also demonstrated that the dimensions enable to construct new service taxonomies which bear essentially on productivity opportunities at the business level. Needles to say the key determinant explaining the development and potential of productivity growth is innovation activity. As an extensive topic of research, however, service innovation is tackled here only in a cursory way. The paper is constructed as follows: the first section focuses on the conceptual issues and evolving nature of service activities. A workable definition of service should capture the diversity of service activities, as well as the aspects of service processes, comprehensively. The distinctions and similarities between services and manufacturing are discussed, too. Section 2 deals with the service productivity, a persistent and controversial issue in academic literature and policy. With the assessments of strengths and weaknesses of the main schools new insights based on value creation will be brought in. Industry classifications and taxonomies are discussed in Section 3. It begins with a short analysis of the official classifications and their evaluation from the perspective of empirical research. Using well-known examples it is shown that the taxonomies on the manufacturing industries have a clear analogy with the business services. As there is a growing interest to regroup services too, the work to date, has been less systematic and inherently qualitative. Based on the earlier contributions threedimensional service taxonomy is constructed which highlight the key dimensions of productive performance. The main findings and implications are summed up in Section 4.

Contract manufacturing networks structure and supply chain management

The usual objectives that companies have for subcontracting are studied in this thesis. The case company’s objectives for contract manufacturing now and in the future are identified. The main objective of the thesis is to create a focused model for the structure and supply chain management in the contract manufacturing network. This model is made for case company’s certain profit center. The different possibilities and their advantages and disadvantages for the structure and supply chain management are examined trough a theoretical review of literature. The possibilities found are then examined from the case company’s point of view. The case company point of view is established based on the opinions of the case company’s representatives. The outcome of the thesis is that the star shaped structure with supply chain management centralized to case company would be the best choice for the case company to manage the contract manufacture network.

Market Opportunities for Paper Industry in Radio Frequency Identification

The paper industry has been experiencing remarkable structural changes since paper demand growth has ceased and some markets are declining. One reason behind the declined demand is the Internet, which has partially substituted the newspaper as a source of information. Paper products alone can no longer provide livelihood, and the paper industry has to find new business areas. In this research, we studied radio frequency identification (RFID), and the market opportunities it could provide for paper industry. The research combined a quantitative industry analysis and qualitative interviews. RFID is a growing industry in the beginning of its life cycle, in which value chains and technologies still evolve significantly. The industry is going to concentrate on the future, and in the long term RFID-identifiers will probably be printed on paper substrate or directly onto products. Paper industry has the chance to enter the RFID industry, but it has to obtain the required competences, for example through acquisitions. The business potential RFID offers to paper industry is inadequate, and while reviewing new strategic options, the paper industry must consider more options, for example the entire printed intelligence.

Guillem Masó, mercader de Sant Joan de les Abadesses: bestiar, draps i crèdit en una vila monàstica al darrer quart del segle XIV

El present treball es fonamenta amb el contingut del llibre particular o extraordinari del mercader Guillem Masó, de Sant Joan de les Abadesses, actiu durant la segona meitat del segle XIV. La majoria d’assentaments que conté el volum fan referència a tractes de bestiar, amb la inclusió de diverses tipologies o variants en els contractes, des de la simple compravenda fins a comandes-parceria. L’activitat del mercader Masó, tanmateix, no se centra exclusivament en aquests negocis. S’intueix una diversificació de les seves activitats que es vinculen, fonamentalment, amb la producció i comercialització de draps de llana i de lli. El context social i econòmic de la vila de Sant Joan durant aquest període afavoreix la presència d’aquests empresaris tèxtils que, per a aconseguir els seus objectius, s’introdueixen en els ressorts del poder civil de la vila i en els dels gremis i confraries que regulen i controlen els processos de fabricació dels productes

Three Wavelength Optical Probe for Surface Roughness Measurements of Paper Samples

In the present diploma work optical inspection methods were used to investigate surface roughness of paper samples. A special measurement setup, which includes three laser light sources of three different wavelengths, photodetector and goniometer, was used to measure the reflected laser light properties. The intensity of the light reflected in specular direction was measured versus the laser incidence angle for reference metal sample. The value of roughness was estimated and compared to initially known value of metal sample roughness. Thus, the measurement equipment and method were validated. Then the reflected intensity was measured versus reflection angle at constant incidence angle for the same metal sample and paper samples under investigation. The final values of the surface roughness were obtained from the analysis of the reflected intensity dependence. The results are in good correlation with other research groups.

Decomposing differences in total factor productivity across firm size

This paper investigates the extent to which the gap in total factor productivity between small and large firms is due to differences in the endowment of factors determining productivity and to the returns associated with these factors. We place particular emphasis on the contribution of differences in the propensity to innovate and in the use of skilled labor across firms of different size. Empirical evidence from a representative sample of Spanish manufacturing firms corroborates that both differences in endowments and returns to innovation and skilled labor significantly contribute to the productivity gap between small and large firms. In addition, it is observed that the contribution of innovation to this gap is caused only by differences in quantity, while differences in returns have no effect; in the case of human capital, however, most of the effect can be attributed to increasing differences in returns between small and large firms.

Has concentration evolved similarly in manufacturing and services? A sensitivity analysis

Our first objective is to compare the degree of concentration in manufacturing and services, with special emphasis on its evolution in these two sectors, using a sensitivity analysis for different concentration indices and different geographic units of analysis: municipalities and local labour systems of Catalonia in 1991 and 2001. Most concentration measures fail to consider the space in which a particular municipality is located. Our second objective is to overcome this problem by applying two different techniques: by using a clustering measure, and by analysing whether the location quotients computed for each municipality and sector present some kind of spatial autocorrelation process. We take special account of the differences in patterns of concentration according to the technological level of the sectors.
