POLITICAL ENVIRONMENT AND BUSINESS DEVELOPMENT IN THE ARCTIC Strategic opportunities and threats for Finnish companies

The Arctic environment is changing constantly. There are several factors that constitute to the rate and immensity of the development. The region differs from the surrounding markets that most of the countries in the region have been used to. Therefore the purpose of the study was to understand how the political environment affects Finnish companies’ strategies and business operations. The issues analyzed were the political environment in the region, the business environment and economic development, and the opportunities and threats that the Finnish companies have in Arctic. The main theories were found from strategic management and market analysis tools. The different theories and definitions were gone through in order to understand the context of the study. This is a qualitative study that uses content analysis as its main method of analyzing the data. Therefore the data analyzed was gathered from already existing material and it was analyzed until the saturation point was found. This was done in order to minimize the risks related to using secondary data. The data collected was then categorized into themes accordingly. First the general political environment in the Arctic was studied, especially the Arctic Council and its work as the main political entity. From there the focus shifted to the business environment and the general opportunities and threats that are found from Arctic economic development. China offered another point of view to this as it represented a non-Arctic state with a keen interest on the region. Lastly the two previous objectives were combined and looked through from a Finnish perspective. Finnish companies have a great starting point to Arctic business and the operational business environment gives them the framework with which they have to operate in. As a conclusion it can be said that there are three main factors leading the Arctic economic development; the climate change, the development of technology, and the political environment. These set the framework with which the companies operating in the region must comply with. The industry that is likely to lead the development is the marine industry. Furthermore it became evident that the Finnish companies operating in the Arctic face many opportunities as well as threats which can be utilized, taken advantage of or controlled through effective strategic management. The key characteristics needed in the region are openness and understanding of the challenging environment and the ability to face and manage the arising challenges.

The physical environment and organizational behavior

Research into organizational behaviour has indicated that there is an inevitable conflict between the needs of the individual and organizational demands. Psychologists have given insights into basic individual needs and contend that satisfaction of these needs constitutes a motivating force which enhances desired behavioural patterns. Behaviouralists have suggested that a basic and pervasive individual need is the culturally determined need for privacy. Anthropologists and environmental psychologists have shown that man's spatial behaviour is observable and predictable and that changes in the physical environment or the way it is perceived are accompanied by concommitant changes in behaviour. Research findings from each of the disciplines have been reviewed in an attempt to show that the physical environment is a significant factor in satisfying the needs of the individual organizational member, hence, a significant influence on organizational behaviour. A model has been generated to show the relationship between the physical setting and behaviour and to underscore the importance of making provisions within the physical setting for the attainment of a culturally determined optimal level of privacy. The physical setting, by providing for this need, becomes a significant factor in reducing the conflict between the individual and the organization and makes for acceptable role behaviour and the fulfilment of organizational goals.

Les relations entre le transport actif et l'environnement urbain : le cas d'usagers du train de banlieue de Montréal

Dans une société où il est plutôt normal de passer beaucoup de temps assis, nous étudions, à partir de l’aménagement, l’intégration de l’activité physique de loisirs et de transport dans les activités et les lieux du quotidien. Cette intégration est relativement peu étudiée dans sa globalité car elle nécessite de prendre en considération les facteurs de l’environnement physique et social, les deux types d’activité physique, les différents lieux fréquentés quotidiennement et elle pose en ce sens de nombreux défis d’ordre méthodologique. Cette vue globale du phénomène s’impose car de plus en plus de recherches font état d’associations entre des dimensions spécifiques de l’aménagement et des comportements précis; occasionnellement, ces résultats se contredisent. Pour comprendre le phénomène, nous sommes partis du modèle écoenvironnemental et l’avons adapté pour mieux représenter la mobilité de la population. Nous avons conséquemment choisi une unité d’analyse comprenant le territoire résidentiel, le territoire du milieu de travail et le trajet entre les deux. Ainsi, en utilisant plusieurs sources de données, nous avons caractérisé des milieux comme étant contraignants ou facilitants pour l’activité physique et les personnes y résidant comme étant suffisamment actives ou pas. Nous avons ensuite fait ressortir les éléments importants des entrevues en fonction de cet appariement. Parmi les thèmes explorés en entrevue, nommons les caractéristiques de l’environnement physique qui ont de l’importance, l’impact de l’environnement social au travail et au domicile, la logique sous-jacente aux courses, etc. Les principaux résultats de cette recherche démontrent que les usagers du train de banlieue font suffisamment d’activité physique en dépit qu’ils résident en banlieue. En ce sens, notre échantillon est plus actif que la moyenne québécoise. Nous remarquons que l’influence de l’environnement est manifeste mais sous le principe des vases communicants, c'est-à-dire que le pôle résidentiel et le pôle des emplois ont tous deux des contributions qui s’avèrent très souvent complémentaires. L’influence de l’environnement social passe par le rôle signifiant des proches plutôt que par leur proximité géographique tandis que l’aménagement a une énorme contribution à rendre les parcours agréables et, de ce fait, donner une plus-value au temps requis pour les emprunter. La vocation des milieux, le type de marche et le sens qu’y voient les usagers doivent guider le design; il n’y a donc pas qu’une formule ou une seule prescription pour augmenter le potentiel piétonnier et/ou cyclable des milieux. Cela dit, les outils de caractérisation doivent être revus. En conclusion des pistes de développements futurs à cette recherche sont proposées.

Assessing inequities in active transportation : does the effect of walkable built environments vary according to neighbourhood socioeconomic status?

Certains chercheurs veulent que les gouvernements modifient les déterminants de l’environnement urbain du transport actif dans des régions à bas statut socioéconomique pour réduire les inégalités en activité physique et santé. Mais, des individus de différents sousgroupes de la population pourraient réagir différemment à l’environnement urbain. Plusieurs chercheurs ont examiné si l’influence d’un environnement urbain propice aux piétons sur le transport actif diffère entre les personnes ayant un statut socioéconomique de quartier différent et ont obtenu des résultats mixtes. Ces résultats équivoques pourraient être dus à la façon dont les mesures de l’environnement urbain étaient déterminées. Plus spécifiquement, la plupart des études ont examiné l’effet de la propicité à la marche des lieux résidentiels et n’ont pas pris en compte les destinations non-résidentielles dans leurs mesures. Cette étude a examiné le statut socioéconomique du quartier comme modérateur de la relation entre l’environnement urbain et le transport actif en utilisant des mesures d’environnement urbain qui proviennent de toute la trajectoire spatiale estimé des individus. Les trois variables de l’environnement urbain, la connectivité, la densité des commerces et services et la diversité du territoire avaient une plus grande influence sur le transport actif de ceux avec un haut statut socioéconomique. Nos résultats suggèrent que même quand la configuration de l’environnement urbain est favorable pour le transport actif, il peut y avoir des barrières sociales ou physiques qui empêchent les gens qui habitent dans un quartier à bas statut socioéconomique de bénéficier d’un environnement urbain favorable au transport actif.

Analysis and Design of an Adaptive Polynomial Predistorter with the Loop Delay Estimator

Most adaptive linearization circuits for the nonlinear amplifier have a feedback loop that returns the output signal oj'tne eunplifier to the lineurizer. The loop delay of the linearizer most be controlled precisely so that the convergence of the linearizer should be assured lot this Letter a delay control circuit is presented. It is a delay lock loop (ULL) with it modified early-lute gate and can he easily applied to a DSP implementation. The proposed DLL circuit is applied to an adaptive linearizer with the use of a polynomial predistorter, and the simulalion for a 16-QAM signal is performed. The simulation results show that the proposed DLL eliminates the delay between the reference input signal and the delayed feedback signal of the linearizing circuit perfectly, so that the predistorter polynomial coefficients converge into the optimum value and a high degree of linearization is achieved

This antenna offers channel isolation better than 25 dB, and is more compact compared to a conventional rectangular patch. Analytical equations for calculating the resonant frequencies at both ports are also presented. The theoretical calculations are verified using experimental results

Linear Low Density Polyethylene-Biodegradability Using Bacteria from Marine Benthic Environment and Photodegradability Using Ultraviolet Light

Various compositions of linear low density polyethylene(LLDPE) containing bio-filler(either starch or dextrin)of various particle sizes were prepared.The mechanical,thermal,FTIR,morphological(SEM),water absorption and melt flow(MFI) studies were carried out.Biodegradability of the compositions were determined using a shake culture flask containing amylase producing bacteria(vibrios),which were isolated from marine benthic environment and by soil burial test. The effect of low quantities of metal oxides and metal stearate as pro-oxidants in LLDPE and in the LLDPE-biofiller compositions was established by exposing the samples to ultraviolet light.The combination of bio-filler and a pro-oxidant improves the degradation of linear low density polyethylene.The maleation of LLDPE improves the compatibility of the c blend components and thepro-oxidants enhance the photodegradability of the compatibilised blends.The responsibility studies on the partially biodegradable LLDPE containing bio-fillers and pro-oxidants suggest that the blends could be repeatedly reprocessed without deterioration in mechanical properties.

FEM based Virtual Prototyping and Design of Third Harmonic Excitation System for Low Voltage Brushless Alternators

Salient pole brushless alternators coupled to IC engines are extensively used as stand-by power supply units for meeting in- dustrial power demands. Design of such generators demands high power to weight ratio, high e ciency and low cost per KVA out- put. Moreover, the performance characteristics of such machines like voltage regulation and short circuit ratio (SCR) are critical when these machines are put into parallel operation and alterna- tors for critical applications like defence and aerospace demand very low harmonic content in the output voltage. While designing such alternators, accurate prediction of machine characteristics, including total harmonic distortion (THD) is essential to mini- mize development cost and time. Total harmonic distortion in the output voltage of alternators should be as low as possible especially when powering very sophis- ticated and critical applications. The output voltage waveform of a practical AC generator is replica of the space distribution of the ux density in the air gap and several factors such as shape of the rotor pole face, core saturation, slotting and style of coil disposition make the realization of a sinusoidal air gap ux wave impossible. These ux harmonics introduce undesirable e ects on the alternator performance like high neutral current due to triplen harmonics, voltage distortion, noise, vibration, excessive heating and also extra losses resulting in poor e ciency, which in turn necessitate de-rating of the machine especially when connected to non-linear loads. As an important control unit of brushless alternator, the excitation system and its dynamic performance has a direct impact on alternator's stability and reliability. The thesis explores design and implementation of an excitation i system utilizing third harmonic ux in the air gap of brushless al- ternators, using an additional auxiliary winding, wound for 1=3rd pole pitch, embedded into the stator slots and electrically iso- lated from the main winding. In the third harmonic excitation system, the combined e ect of two auxiliary windings, one with 2=3rd pitch and another third harmonic winding with 1=3rd pitch, are used to ensure good voltage regulation without an electronic automatic voltage regulator (AVR) and also reduces the total harmonic content in the output voltage, cost e ectively. The design of the third harmonic winding by analytic methods demands accurate calculation of third harmonic ux density in the air gap of the machine. However, precise estimation of the amplitude of third harmonic ux in the air gap of a machine by conventional design procedures is di cult due to complex geome- try of the machine and non-linear characteristics of the magnetic materials. As such, prediction of the eld parameters by conven- tional design methods is unreliable and hence virtual prototyping of the machine is done to enable accurate design of the third har- monic excitation system. In the design and development cycle of electrical machines, it is recognized that the use of analytical and experimental methods followed by expensive and in exible prototyping is time consum- ing and no longer cost e ective. Due to advancements in com- putational capabilities over recent years, nite element method (FEM) based virtual prototyping has become an attractive al- ternative to well established semi-analytical and empirical design methods as well as to the still popular trial and error approach followed by the costly and time consuming prototyping. Hence, by virtually prototyping the alternator using FEM, the important performance characteristics of the machine are predicted. Design of third harmonic excitation system is done with the help of results obtained from virtual prototype of the machine. Third harmonic excitation (THE) system is implemented in a 45 KVA ii experimental machine and experiments are conducted to validate the simulation results. Simulation and experimental results show that by utilizing third harmonic ux in the air gap of the ma- chine for excitation purposes during loaded conditions, triplen harmonic content in the output phase voltage is signi cantly re- duced. The prototype machine with third harmonic excitation system designed and developed based on FEM analysis proved to be economical due to its simplicity and has the added advan- tage of reduced harmonics in the output phase voltage.

Simulation and Design of a high speed Solid State Switch for Excimer Laser

Excimerlaser sind gepulste Gaslaser, die Laseremission in Form von Linienstrahlung – abhängig von der Gasmischung – im UV erzeugen. Der erste entladungsgepumpte Excimerlaser wurde 1977 von Ischenko demonstriert. Alle kommerziell verfügbaren Excimerlaser sind entladungsgepumpte Systeme. Um eine Inversion der Besetzungsdichte zu erhalten, die notwendig ist, um den Laser zum Anschwingen zu bekommen, muss aufgrund der kurzen Wellenlänge sehr stark gepumpt werden. Diese Pumpleistung muss von einem Impulsleistungsmodul erzeugt werden. Als Schaltelement gebräuchlich sind Thyratrons, Niederdruckschaltröhren, deren Lebensdauer jedoch sehr limitiert ist. Deshalb haben sich seit Mitte der 1990iger Jahre Halbleiterschalter mit Pulskompressionsstufen auch in dieser Anwendung mehr und mehr durchgesetzt. In dieser Arbeit wird versucht, die Pulskompression durch einen direkt schaltenden Halbleiterstapel zu ersetzen und dadurch die Verluste zu reduzieren sowie den Aufwand für diese Pulskompression einzusparen. Zudem kann auch die maximal mögliche Repetitionsrate erhöht werden. Um die Belastung der Bauelemente zu berechnen, wurden für alle Komponenten möglichst einfache, aber leistungsfähige Modelle entwickelt. Da die normalerweise verfügbaren Daten der Bauelemente sich aber auf andere Applikationen beziehen, mussten für alle Bauteile grundlegende Messungen im Zeitbereich der späteren Applikation gemacht werden. Für die nichtlinearen Induktivitäten wurde ein einfaches Testverfahren entwickelt um die Verluste bei sehr hohen Magnetisierungsgeschwindigkeiten zu bestimmen. Diese Messungen sind die Grundlagen für das Modell, das im Wesentlichen eine stromabhängige Induktivität beschreibt. Dieses Modell wurde für den „magnetic assist“ benützt, der die Einschaltverluste in den Halbleitern reduziert. Die Impulskondensatoren wurden ebenfalls mit einem in der Arbeit entwickelten Verfahren nahe den späteren Einsatzparametern vermessen. Dabei zeigte sich, dass die sehr gebräuchlichen Class II Keramikkondensatoren für diese Anwendung nicht geeignet sind. In der Arbeit wurden deshalb Class I Hochspannungs- Vielschicht- Kondensatoren als Speicherbank verwendet, die ein deutlich besseres Verhalten zeigen. Die eingesetzten Halbleiterelemente wurden ebenfalls in einem Testverfahren nahe den späteren Einsatzparametern vermessen. Dabei zeigte sich, dass nur moderne Leistungs-MOSFET´s für diesen Einsatz geeignet sind. Bei den Dioden ergab sich, dass nur Siliziumkarbid (SiC) Schottky Dioden für die Applikation einsetzbar sind. Für die Anwendung sind prinzipiell verschiedene Topologien möglich. Bei näherer Betrachtung zeigt sich jedoch, dass nur die C-C Transfer Anordnung die gewünschten Ergebnisse liefern kann. Diese Topologie wurde realisiert. Sie besteht im Wesentlichen aus einer Speicherbank, die vom Netzteil aufgeladen wird. Aus dieser wird dann die Energie in den Laserkopf über den Schalter transferiert. Aufgrund der hohen Spannungen und Ströme müssen 24 Schaltelemente in Serie und je 4 parallel geschaltet werden. Die Ansteuerung der Schalter wird über hochisolierende „Gate“-Transformatoren erreicht. Es zeigte sich, dass eine sorgfältig ausgelegte dynamische und statische Spannungsteilung für einen sicheren Betrieb notwendig ist. In der Arbeit konnte ein Betrieb mit realer Laserkammer als Last bis 6 kHz realisiert werden, der nur durch die maximal mögliche Repetitionsrate der Laserkammer begrenzt war.

The institutional environment and its influence on political options to Protect Winnipeg’s Female garments Workers against the impact of globalization

The principal objective of this paper is to identify the relationship between the re­sults of the Canadian policies implemented to protect female workers against the impact of globalization on the garment industry and the institutional setting in which this labour market is immersed in Winnipeg. This research paper begins with a brief summary of the institutional theory appro­ach that sheds light on the analysis of the effects of institutions on the policy options to protect female workers of the Winnipeg garment industry. Next, this paper identi­fies the set of beliefs, formal procedures, routines, norms and conventions that cha­racterize the institutional environment of the female workers of Winnipeg’s garment industry. Subsequently, this paper descri­bes the impact of free trade policies on the garment industry of Winnipeg. Afterward, this paper presents an analysis of the ba­rriers that the institutional features of the garment sector in Winnipeg can set to the successful achievement of policy options addressed to protect the female workforce of this sector. Three policy options are considered: ethical purchasing; training/retraining programs and social engage­ment support for garment workers; and protection of migrated workers through promoting and facilitating bonds between Canada’s trade unions and trade unions of the labour sending countries. Finally, this paper concludes that the formation of isolated cultural groups inside of factories; the belief that there is gender and race discrimination on the part of the garment industry management against workers; the powerless social conditions of immi­grant women; the economic rationality of garment factories’ managers; and the lack of political will on the part of Canada and the labour sending countries to set effective bilateral agreements to protect migrate wor­kers, are the principal barriers that divide the actors involved in the garment industry in Winnipeg. This division among the prin­cipal actors of Winnipeg’s garment industry impedes the change toward more efficient institutions and, hence, the successful achievement of policy options addressed to protect women workers.
