Competitor Information andCompetitive Knowledge Management in a Large Industrial Organization

Thisthesis supplements the systematic approach to competitive intelligence and competitor analysis by introducing an information-processing perspective on management of the competitive environment and competitors therein. The cognitive questions connected to the intelligence process and also the means that organizational actors use in sharing information are discussed. The ultimate aim has been to deepen knowledge of the different intraorganizational processes that are used in acorporate organization to manage and exploit the vast amount of competitor information that is received from the environment. Competitor information and competitive knowledge management is examined as a process, where organizational actorsidentify and perceive the competitive environment by using cognitive simplification, make interpretations resulting in learning and finally utilize competitor information and competitive knowledge in their work processes. The sharing of competitive information and competitive knowledge is facilitated by intraorganizational networks that evolve as a means of developing a shared, organizational level knowledge structure and ensuring that the right information is in the right place at the right time. This thesis approaches competitor information and competitive knowledge management both theoretically and empirically. Based on the conceptual framework developed by theoretical elaboration, further understanding of the studied phenomena is sought by an empirical study. The empirical research was carried out in a multinationally operating forest industry company. This thesis makes some preliminary suggestions of improving the competitive intelligence process. It is concluded that managing competitor information and competitive knowledge is not simply a question of managing information flow or improving sophistication of competitor analysis, but the crucial question to be solved is rather, how to improve the cognitive capabilities connected to identifying and making interpretations of the competitive environment and how to increase learning. It is claimed that competitive intelligence can not be treated like an organizational function or assigned solely to a specialized intelligence unit.

Permanent magnet synchronous motor for industrial inverter applications - analysis and design

During the latest few years the need for new motor types has grown, since both high efficiency and an accurate dynamic performance are demanded in industrial applications. For this reason, new effective control systems such as direct torque control (DTC) have been developed. Permanent magnet synchronous motors (PMSM) are well suitable for new adjustable speed AC inverter drives, because their efficiency and power factor are not depending on the pole pair number and speed to the same extent as it is the case in induction motors. Therefore, an induction motor (IM) with a mechanical gearbox can often be replaced with a direct PM motor drive. Space as well as costs will be saved, because the efficiency increases and the cost of maintenance decreases as well. This thesis deals with design criterion, analytical calculation and analysis of the permanent magnet synchronous motor for both sinusoidal air-gap flux density and rectangular air-gapflux density. It is examined how the air-gap flux, flux densities, inductances and torque can be estimated analytically for salient pole and non-salient pole motors. It has been sought by means of analytical calculations for the ultimate construction for machines rotating at relative low 300 rpm to 600 rpm speeds, which are suitable speeds e.g. in Pulp&Paper industry. The calculations are verified by using Finite Element calculations and by measuring of prototype motor. The prototype motor is a 45 kW, 600 rpm PMSM with buried V-magnets, which is a very appropriate construction for high torque motors with a high performance. With the purposebuilt prototype machine it is possible not only to verify the analytical calculations but also to show whether the 600 rpm PMSM can replace the 1500 rpm IM with a gear. It can also be tested if the outer dimensions of the PMSM may be the same as for the IM and if the PMSM in this case can produce a 2.5 fold torque, in consequence of which it may be possible to achieve the same power. The thesis also considers the question how to design a permanent magnet synchronous motor for relatively low speed applications that require a high motor torqueand efficiency as well as bearable costs of permanent magnet materials. It is shown how a selection of different parameters affects the motor properties. Key words: Permanent magnet synchronous motor, PMSM, surface magnets, buried magnets

Unas reflexiones sobre localización industrial aplicadas a la industria catalana

El trabajo es una reflexión sobre las pautas de localización industrial,con una especial referencia a la industria de la economía catalana. En el estudio se realiza una revisión de los principales factores explicativos de la localización y aglomeración industrial defendidos por las teorías de la localización. Con estos argumentos de base, posteriormente el análisis se aplica a una división de catorce grandes sectores industriales catalanes. El objetivo es llegar a conclusiones acerca de si los sectores en los que la industria catalana muestra mayor grado de especialización son también aquellos que, a tenor de los principales factores que inciden en la localización industrial, tienen mayor riesgo de sufrir futuras deslocalizaciones.

Caracterización de las almazaras cooperativas catalanas, análisis interno de la fase industrial o de transformación

En el presente artículo hemos tratado de analizar las características de las almazaras cooperativas catalanas con la finalidad de destacar no solamente sus elementos más importantes de gestión sino también sus principales debilidades.Las cooperativas se consideran instrumentos útiles para acometer políticas de desarrollo económico y bienestar social. A pesar de ello hay un gran debate abierto acerca de la eficiencia de estas organizaciones, que plantean el interrogante de si están en condiciones de competir con éxito en una economía cada vez más abierta, liberalizada y global. A través de las encuestas que hemos realizado al conjunto de las cooperativas oleícolas de Catalunya, hemos podido averiguar sus características distintivas, así como las principales desventajas y problemas a los que se enfrentan. Creemos puede ser de interés analizar las características de estas organizaciones, que tanto desde el punto de vista organizativo como de recursos humanos, como financiero, las hace diferentes de otro tipo de organizaciones pero que sin embargo, han de hacer frente a un mercado cada día más exigente y competitivo.

Aproximación multicriterio a la estructura industrial de la economía española

El trabajo presenta una forma alternativa de analizar la estructura industrial de la economía española. En concreto, el estudio se interesa tanto por la vertiente de la estructura productiva sectorial, como por la vertiente de la especialización territorial. Mediante la técnica multicriterio se acceden a programas de optimización que, a partir de las variables que se consideran más relevantes (empleo, valor añadido y número de establecimientos) determina, por un lado, qué sectores son los más significativos dentro del tejido industrial de la economía española, y por otro lado, se llega a determinar qué Comunidades Autónomas son las que adquieren mayor peso relativo para cada uno de los sectores industriales.

Factores determinantes de la concentración industrial de la economía española

El objetivo de este trabajo es exponer cuáles son los factores que han influido en el modelo de concentración industrial de la economía española y analizar si son los que postulan las teorías más significativas del comercio. El análisis se realiza en dos momentos distintos del tiempo para evaluar si se han producido cambios significativos. A partir de los índices de concentración relativa y absoluta, calculados para los años 1995 y 2003, sobre 24 sectores de las 17 CCAA, se construyen dos modelos de regresión que son los que permiten el análisis del mapa industrial. Los resultados indican que la localización de la industria puede explicarse en gran medida por las variables sugeridas por las teorías del comercio y que entre ambos periodos no ha habido grandes cambios en los patrones de concentración. Asimismo, el factor que se revela como más determinante de la concentración relativa y absoluta de la industria española es el tamaño y acceso a los mercados.

La decisión de endeudamiento y los factores de mayor relevancia. Una aplicación empírica en la empresa industrial española

El presente trabajo aborda el estudio de los factores determinantes del endeudamiento empresarial para contrastar empíricamente la hipótesis del Pecking Order. El endeudamiento empresarial se mide junto a su madurez y para los diferentes tamaños empresariales dada la importancia de diferenciar sus posibles efectos contrapuestos o compensados. Los modelos utilizados para el contraste de hipótesis se han estimado con una muestra de 1.320 empresas manufactureras españolas proporcionada por la Encuesta sobre Estrategias Empresariales (ESEE), para el período 1993-2001. El análisis empírico aplica un modelo multivariante de regresión logística que permite concluir que la teoría del Pecking Order es la de mejor cumplimiento, además de constatarse que las empresas de menor tamaño tienen mayores dificultades de acceso a la financiación con deuda a largo plazo.

The effect of age at the first mating and herd size on the lifetime productivity of sows

The effect of age at the first mating and herd size were evaluated in the reference Spanish Databank (BDporc) of 37 698 sows born between 1991 and 1995 and with individual lifetime records. The data included dates of births at entrance and culling, first mating, repetitive mating and conception, first farrowing and weaning records. Individual records were validated before the analysis by screening them through a tolerance “filter” in order to eliminate the extreme values from the analysis. The total database of the sows was classified in 7 classes according to age at the first mating (< 210, 210–220, 221–230, 231–240, 241–250, 251–270, and > 270 days) and in 6 classes of herd size (< 200, 200–300, 301–400, 401–600, 601–800, and > 800 sows). The total number of litters and number of weaned piglets obtained from each sow during the lifetime production were significantly (P < 0.05) greater for gilts between 221 and 240 d of age at the first mating. There was a significant (P < 0.001) effect of the herd size on the reproductive performance of the sow, and the best performance was obtained with herds with 401 to 600 sows compared to < 200 or > 800 sow-herds. Furthermore, a significant (P < 0.001) interaction between age at the first mating and herd size was detected and can be associated with a particular pattern for the herd size class 401–600 sows with the best performances obtained for the sows first mated at less than 200 days. For the other herd sizes, the results indicated that sows mated for the first time at the right age, 221–240 days, are more productive, both in the number and size of the parities throughout lifetime production.

Engineered Trx2p industrial yeast strain protects glycolysis and fermentation proteins from oxidative carbonylation during biomass propagation

Background: In the yeast biomass production process, protein carbonylation has severe adverse effects since it diminishes biomass yield and profitability of industrial production plants. However, this significant detriment of yeast performance can be alleviated by increasing thioredoxins levels. Thioredoxins are important antioxidant defenses implicated in many functions in cells, and their primordial functions include scavenging of reactive oxygen species that produce dramatic and irreversible alterations such as protein carbonylation. Results: In this work we have found several proteins specifically protected by yeast Thioredoxin 2 (Trx2p). Bidimensional electrophoresis and carbonylated protein identification from TRX-deficient and TRX-overexpressing cells revealed that glycolysis and fermentation-related proteins are specific targets of Trx2p protection. Indeed, the TRX2 overexpressing strain presented increased activity of the central carbon metabolism enzymes. Interestingly, Trx2p specifically preserved alcohol dehydrogenase I (Adh1p) from carbonylation, decreased oligomer aggregates and increased its enzymatic activity. Conclusions: The identified proteins suggest that the fermentative capacity detriment observed under industrial conditions in T73 wine commercial strain results from the oxidative carbonylation of specific glycolytic and fermentation enzymes. Indeed, increased thioredoxin levels enhance the performance of key fermentation enzymes such as Adh1p, which consequently increases fermentative capacity.

Irrigation performance and gross water productivity in furrow-irrigated ornamental tree production

In the ornamental plant production region of Girona (Spain), which is one of the largest of its kind in southern Europe, most of the surface is irrigated using wide blocked-end furrows. The objectives of this paper were: (1) to evaluate the irrigation scheduling methods used by ornamental plant producers; (2) to analyse different scenarios in order to assess how they affect irrigation performance; (3) to evaluate the risk of deep percolation; and (4) to calculate gross water productivity. A two-year study in a representative commercial field, planted with Prunus cerasifera ‘Nigra’, was carried out. The irrigation dose applied by the farmers was slightly smaller than the required water dose estimated by the use of two different methods: the first based on soil water content, and the second based on evapotranspiration. Distribution uniformity and application eff iciency were high, with mean values above 87%. Soil water content measurements revealed that even at the end of the furrow, where the infiltrated water depth was greatest, more than 90% of the infiltrated water was retained in the shallowest 40 cm of the soil; accordingly, the risk of water loss due to deep percolation was minimal. Gross water productivity for ornamental tree production was € 11.70 m–3, approximately 20 times higher than that obtained with maize in the same region.

El tren d'alta velocitat i el teixit industrial a la regió de Lleida

Per entendre el possible impacte del tren d'alta velocitat a Lleida s'han analitzat exemples de França (línia París-Lió) i Alemanya (Mannheim), on el tren d'alta velocitat competeix favorablement amb l'autopista en trajectes de més d'una hora o una hora i mitja, i amb l'avió en trajectes de fins a 3 hores. Les estacions urbanes de les grans aglomeracions, dotades amb un bon transport públic, se'n beneficien de la seva centralitat i de la realimentació mútua entre serveis, mentre que les situades a fora dels nuclis han vist com el servei inicial s'ha degradat per manca de clientela suficient. L'arribada del tren d'alta velocitat a una estació central s'aprofita sovint per renovar-la, cosa que afecta també el seu entorn i, de vegades, el barri sencer. El tren d'alta velocitat, doncs, augmenta la centralitat i, en alguns casos, motiva una descentralització concentrada de les metròpolis a les ciutats mitjanes. A més, provoca noves pautes de localització i afavoreix un funcionament més eficaç de les empreses dels sectors sensibles. El sector agroalimentari i alguns serveis presents a Lleida poden gaudir d'aquest afavoriment si es tecnifiquen i se situen en un grau de qualificació alt.

Qualidade industrial e maturação de frutos de laranjeira "valência" sobre seis porta-enxertos

Com o objetivo de avaliar a influência de seis porta-enxertos sobre a maturação e as características físico-químicas de frutos de laranjeira 'Valência', instalou-se um experimento em janeiro de 1994, no município de Nova Esperança-PR. O delineamento experimental foi de blocos ao acaso, com quatro repetições, três plantas úteis por parcela e seis tratamentos, constituídos pelos porta-enxertos: limoeiro 'Cravo' (Citrus limonia), tangerineiras 'Cleópatra' (C. reshni) e 'Sunki' (C. sunki), citrangeiro 'Troyer' (Poncirus trifoliata x C. sinensis), tangeleiro 'orlando' (C. tangerina x C. paradisi) e laranjeira 'Caipira'(C. sinensis). Avaliou-se a qualidade dos frutos em sete safras e a curva de maturação foi estimada para os anos de 1999 e 2000. Todos os porta-enxertos proporcionaram qualidade aceitável aos frutos da laranjeira 'Valência', com destaque para o citrangeiro 'Troyer' que superou o limoeiro 'Cravo' em rendimento industrial. Em um ano considerado com padrão climático normal, a evolução do índice tecnológico ajustou-se a uma equação de regressão quadrática, proporcionando melhor rendimento industrial quando os frutos foram colhidos no início de novembro, independentemente do porta-enxerto utilizado.
