La implicación de las provincias canadienses en la competencia sobre inmigración

El presente artículo se centra en el estudio de los acuerdos de inmigración celebrados a partir de la década de los noventa entre la Federación y las provincias canadienses (a excepción de Quebec). Los acuerdos incluyen tanto la posibilidad de seleccionar una parte de la inmigración que llega al territorio de cada provincia, como la gestión provincial de los programas de primera acogida e integración. En la primera parte se estudian los acuerdos firmados con Manitoba, Alberta, British Columbia y Ontario, para posteriormente analizar el impacto de los mismos tanto en el modelo migratorio, como en el modelo federal canadiense. El artículo concluye que los acuerdos han disminuido el nivel de asimetría en relación a la competencia sobre inmigración, pero sin llegar a eliminarla. Además, la gestión realizada por las provincias pone en evidencia la necesidad de repasar los perfiles migratorios altamente cualificados y la necesidad de implementar mecanismos de coordinación para evitar distorsiones en el modelo migratorio.

Change of Electricity Distribution Industry: Drivers and Opening Business Opportunities

As a result of the recent regulatory amendments and other development trends in the electricity distribution business, the sector is currently witnessing radical restructuring that will eventually impact the business logics of the sector. This report represents upcoming changes in the electricity distribution industry and concentrates on the factors that are expected to be the most fundamental ones. Electricity network companies nowadays struggle with legislative and regulatory requirements that focus on both the operational efficiency and the reliability of electricity distribution networks. The forces that have an impact on the distribution network companies can be put into three main categories that define the transformation at a general level. Those are: (1) a requirement for a more functional marketplace for energy, (2) environmental aspects (combating climate change etc.), and (3) a strongly emphasized requirement for the security of energy supply. The first point arises from the legislators’ attempt to increase competition in electricity retail markets, the second one concerns both environmental protection and human safety issues, and the third one indicates societies’ reduced willingness to accept interruptions in electricity supply. In the future, regulation of electricity distribution business may lower the threshold for building more weather-resistant networks, which in turn means increased underground cabling. This development pattern is reinforced by tightening safety and environmental regulations that ultimately make the overhead lines expensive to build and maintain. The changes will require new approaches particularly in network planning, construction, and maintenance. The concept for planning, constructing, and maintaining cable networks is necessary because the interdependencies between network operations are strong, in other words, the nature of the operation requires a linkage to other operations.

De resíduo a insumo: a construção do caminho para uma química mais limpa através de um projeto de ensino

The discussion among teachers, students, and technicians about the destination of residues from chemistry laboratories led to a research project whose results were incorporated into a course in its daily practices. The treatment of the residues from argentimetric practices allowed us to establish cognitive relations of technological basis and of those related to the rising of the level of awareness about environmental aspects and social responsibility of chemistry professionals. The techniques and the results, from the economic point of view, namely that of value aggregation (metallic silver) and the conversion of the residue into input (potassium chromate solution) are shown.

Ecodesign-direktiivi ja sen vaikutukset Suomessa

Direktiivi 2005/32/EY energiaa käyttävien tuotteiden ekologiselle suunnittelulle asetettavien vaatimusten puitteista annettiin 6.7.2005. Direktiivin puitteissa Euroopan komissio tulee antamaan tuoteryhmäkohtaisia asetuksia, joissa määritellään tuoteryhmäkohtaisesti ympäristövaatimukset. Direktiivin tarkoituksena on integroida ymparistönakokohdat ja elinkaariajattelu tuotesuunnitteluvaiheessa. Tällä direktiivillä pyritään parantamaan ympäristösuojelun tasoa ja tuotteiden energiatehokkuutta. Tämän diplomityön tarkoituksena on esitellä Ecodesign direktiiviä ja selvittää sen puitteissa annettujen asetusten vaikutusta Suomessa.

Tarkasteluun valitut tuoteryhmät olivat kotitalouksien valaistus ja sähkömoottorit.

Can salvage logging affect seed dispersal by birds into burned forests?

The recovery of vegetation in Mediterranean ecosystems after wildfire is mostly a result of direct regeneration, since the same species existing before the fire regenerate on-site by seeding or resprouting. However, the possibility of plant colonization by dispersal of seeds from unburned areas remains poorly studied. We addressed the role of the frugivorous, bird-dependent seed dispersal (seed rain) of fleshy-fruited plants in a burned and managed forest in the second winter after a fire, before on-site fruit production had begun. We also assessed the effect on seed rain of different microhabitats resulting from salvage logging (erosion barriers, standing snags, open areas), as well as the microhabitats of unlogged patches and an unburned control forest, taking account of the importance of perches as seed rain sites. We found considerable seed rain by birds in the burned area. Seeds, mostly from Olive trees Olea europaea and Evergreen pistaches Pistacia lentiscus, belonged to plants fruiting only in surrounding unburned areas. Seed rain was heterogeneous, and depended on microhabitat, with the highest seed density in the unburned control forest but closely followed by the wood piles of erosion barriers. In contrast, very low densities were found under perches of standing snags. Furthermore, frugivorous bird richness seemed to be higher in the erosion barriers than elsewhere. Our results highlight the importance of this specific post-fire management in bird-dependent seed rain and also may suggest a consequent heterogeneous distribution of fleshy-fruited plants in burned and managed areas. However, there needs to be more study of the establishment success of dispersed seeds before an accurate assessment can be made of the role of bird-mediated seed dispersal in post-fire regeneration

Dinámica del heleoplancton en relación a las fluctuaciones hidrológicas en aiguamolls de l’Empordà (NE de la península Ibérica). Propuesta de un método sencillo de monitorización basado en la abundancia de grupos taxonómicos

Monitoring of the 'ecological water quality' in 'Aiguamolls de l’Empordà' Natural Park was carried out between September 1996 and August 1997 . The aim of this sampling programme was to design a simple method for rapid detect changes in water quality due to human activity. These include flow regulation by the Park management, nutrient entries from effluents of a nearby wastewater treatment plant or agricultural fertilising. The proposed method is based on the analysis of the abundance of characteristic taxonomic groups of aquatic invertebrates (heleoplankton). The simplicity of the method is ensured by the use of large taxa which are easier to recognise than species. The functioning of aquatic systems has been modelled by means of correspondence analysis between samples and taxa. Results can be summerized in five environmental conditions with a regular community structure. Dominated by one taxon: cladocerans, ostracods, calanoids, cyclopoids and harpacticoids. The dynamics of both freshwater and brackish lagoons can be modelled as displacements between these five groups of environmental conditions. Nevertheless, the “calanoids situation” and the “harpacticoids situation” occur mainly in brackish lagoons, whereas the “cladocerans situation” occurs mainly in freshwater. The four principal axes of data variation have been respectively identified as nutrient turnover rate, hypertrophy, degree of mineralization of the organic matter and eutrophy. The use of these taxa has been validated by comparison with a model obtained from the species. We conclude that in a highly fluctuating system such as the one here, only persistent situations of eutrophy or hypertrophy must be equated to low 'ecological water quality'

A gestão de resíduos de laboratório na visão de alunos de um curso de graduação de quimica e áreas afins

This work presents the students´ profile before and after working in the course "Laboratory Chemical Waste Treatment" in the last ten years. The structure of the course is also described. Although students have shown an increasing previous experience on waste management, many fundamental aspects are missing, especially knowledge on the directives focusing environmental aspects. Visits to industrial plants are also essential to better understand the impact of wastes in environment. Most students nowadays consider waste management as an essential part of their professional formation. A good waste management program must consider several topics of extreme relevance.

Training system for conceptual design and evaluation for wastewater treatment

Rising population, rapid urbanisation and growing industrialisation have severely stressed water quality and its availability in Malawi. In addition, financial and institutional problems and the expanding agro industry have aggravated this problem. The situation is worsened by depleting water resources and pollution from untreated sewage and industrial effluent. The increasing scarcity of clean water calls for the need for appropriate management of available water resources. There is also demand for a training system for conceptual design and evaluation for wastewater treatment in order to build the capacity for technical service providers and environmental practitioners in the country. It is predicted that Malawi will face a water stress situation by 2025. In the city of Blantyre, this situation is aggravated by the serious pollution threat from the grossly inadequate sewage treatment capacity. This capacity is only 23.5% of the wastewater being generated presently. In addition, limited or non-existent industrial effluent treatment has contributed to the severe water quality degradation. This situation poses a threat to the ecologically fragile and sensitive receiving water courses within the city. This water is used for domestic purposes further downstream. This manuscript outlines the legal and policy framework for wastewater treatment in Malawi. The manuscript also evaluates the existing wastewater treatment systems in Blantyre. This evaluation aims at determining if the effluent levels at the municipal plants conform to existing standards and guidelines and other associated policy and regulatory frameworks. The raw material at all the three municipal plants is sewage. The typical wastewater parameters are Biochemical Oxygen Demand (BOD5), Chemical Oxygen Demand (COD), and Total Suspended Solids (TSS). The treatment target is BOD5, COD, and TSS reduction. Typical wastewater parameters at the wastewater treatment plant at MDW&S textile and garments factory are BOD5 and COD. The treatment target is to reduce BOD5 and COD. The manuscript further evaluates a design approach of the three municipal wastewater treatment plants in the city and the wastewater treatment plant at Mapeto David Whitehead & Sons (MDW&S) textile and garments factory. This evaluation utilises case-based design and case-based reasoning principles in the ED-WAVE tool to determine if there is potential for the tool in Blantyre. The manuscript finally evaluates the technology selection process for appropriate wastewater treatment systems for the city of Blantyre. The criteria for selection of appropriate wastewater treatment systems are discussed. Decision support tools and the decision tree making process for technology selection are also discussed. Based on the treatment targets and design criteria at the eight cases evaluated in this manuscript in reference to similar cases in the ED-WAVE tool, this work confirms the practical use of case-based design and case-based reasoning principles in the ED-WAVE tool in the design and evaluation of wastewater treatment 6 systems in sub-Sahara Africa, using Blantyre, Malawi, as the case study area. After encountering a new situation, already collected decision scenarios (cases) are invoked and modified in order to arrive at a particular design alternative. What is necessary, however, is to appropriately modify the case arrived at through the Case Study Manager in order to come up with a design appropriate to the local situation taking into account technical, socio-economic and environmental aspects. This work provides a training system for conceptual design and evaluation for wastewater treatment.

Ympäristönäkökohtien huomioiminen asumisen läheisyyteen sijoitettavassa maanpäällisessä kivilinjassa

Työn tavoitteena oli selvittää, miten asutuksen läheisyydessä sijaitsevasta kivilinjasta aiheutuvat merkittävät ympäristövaikutukset muuttuvat, kun kivilinja siirretään kallion sisältä maan pinnalle. Kivilinjan aiheuttamia merkittäviä ympäristövaikutuksia ovat erityisesti melu ja pöly. Lisäksi työssä tarkasteltiin toiminnan muutoksesta aiheutuvia vaikutuksia kasvillisuuteen ja eläimistöön, liikennevirtoihin sekä pinta- ja pohjavesiin. Työssä tarkasteltiin myös uuden kivilinjan vaikutuksia yrityksen sisäisiin ympäristönäkökohtiin, kuten työolosuhteiden hallintaan. Työssä laskettiin äänitaso lähimmässä häiriintyvässä kohteessa uuden kivilinjan rakentamisen jälkeen. Äänitaso ei todennäköisesti uuden kivilinjan käyttöönoton myötä tule ylittämään ympäristöluvassa asetettuja raja-arvoja. Kasvillisuuteen ja eläimistöön uudella kivilinjalla voi olla sekä positiivisia että negatiivisia vaikutuksia. Vesistövaikutukset eivät todennäköisesti tule olemaan merkittäviä. Alueen liikennevirtoihin tulee uuden kivilinjan käyttöönoton myötä muutoksia. Ajettavien kilometrien määrä vähenee noin 18 000 kilometriä. Erityisesti prosessin loppupään ajokilometrit vähenevät huomattavasti.

Swine wastewater associated with mineral fertilization on corn crop (Zea mays)

This study aimed to evaluate the agronomical and environmental aspects in corn, soil characteristics and leachate resulting from the material combination of swine wastewater and mineral fertilizer in the long run. The experimental area has a history of swine wastewater application for experiments conducted since 2006, this being the seventh crop cycle in the area. Four doses of swine wastewater (0; 100; 200 and 300 m³ ha-1) associated with presence and absence of mineral fertilizer were applied, consisting of eight treatments. The results obtained were subjected to variance analysis and means compared by Tukey test at 5% significance. We conclude that the swine wastewater can be partially used as an alternative fertilizer, since the P and Mn are complemented with specific fertilization. There must be carefulness about Fe+2, Cu+2 and Zn+2 accumulation in soil, and also to the concentrations of Fe+2, Cu+2, Zn+2, NO3- + NO2- and Na+ in leachate which exceeded the limits at the highest SWW applied levels.

E-PORT. Improving efficiency of Finnish port community by intelligent systems Final report of the Mobile Port project

The management of port-related supply chains is challenging due to the complex and heterogeneous operations of the ports with several actors and processes. That is why the importance of information sharing is emphasised in the ports. However, the information exchange between different port-related actors is often cumbersome and it still involves a lot of manual work and paper. Major ports and port-related actors usually have advanced information systems in daily use but these systems are seldom interoperable with each other, which prevents economies of scale to be reached. Smaller ports and companies might not be equipped with electronic data transmission at all. This is the final report of the Mobile port (MOPO) project, which has sought ways to improve the management and control of port-related sea and inland traffic with the aid of ICT technologies. The project has studied port community systems (PCS) used worldwide, evaluated the suitability of a PCS for the Finnish port operating environment and created a pilot solution of a Finnish PCS in the port of HaminaKotka. Further, the dry port concept and its influences on the transportation system have been explored. The Mobile Port project comprised of several literature reviews, interviews of over 50 port-related logistics and/or ICT professionals, two different kinds of simulation models as well as designing and implementing of the pilot solution of the Finnish PCS. The results of these multiple studies are summarised in this report. Furthermore, recommendations for future actions and the topics for further studies are addressed in the report. The study revealed that the information sharing in a typical Finnish port-related supply chain contains several bottlenecks that cause delays in shipments and waste resources. The study showed that many of these bottlenecks could be solved by building a port community system for the Finnish port community. Almost 30 different kinds of potential services or service entities of a Finnish PCS were found out during the study. The basic requirements, structure, interfaces and operation model of the Finnish PCS were also defined in the study. On the basis of the results of the study, a pilot solution of the Finnish PCS was implemented in the port of HaminaKotka. The pilot solution includes a Portconnect portal for the Finnish port community system (available at https://www.portconnect.fi) and two pilot applications, which are a service for handling the information flows concerning the movements of railway wagons and a service for handling the information flows between Finnish ports and Finland-Russian border. The study also showed that port community systems can be used to improve the environmental aspects of logistics in two different ways: 1) PCSs can bring direct environmental benefits and 2) PCSs can be used as an environmental tool in a port community. On the basis of the study, the development of the Finnish port community system should be continued by surveying other potential applications for the Finnish PCS. It is also important to study if there is need and resources to extend the Finnish PCS to operate in several ports or even on a national level. In the long run, it could be reasonable to clarify whether there would be possibilities to connect the Finnish PCS as a part of Baltic Sea wide, European-wide or even worldwide maritime and port-related network in order to get the best benefit from the system

DIGITAL BUSINESS-TO-BUSINESS MARKETING COMMUNICATIONS IN EMERGING MARKETS – Developing Business Marketing in Russia

The core idea of this Master's Thesis was that five key characteristics – market heterogeneity, sociopolitical governance, chronic shortage of resources, unbranded competition, and inadequate infrastructure – of emerging markets are radically different from the traditional industrialized capitalist society and they will require us to rethink the core assumptions of business-to-business marketing, such as business relationships, marketing communication elements, and digitalization. In this research, Russia is considered to be an emerging market that reflects the aforementioned theoretical characteristics. The research was a qualitative case study and furthermore a collective case study. In the beginning three digital marketing professionals were interviewed to better understand digital B2B marketing. The actual research data was collected through seven structured theme interviews with representatives of the case companies operating in Russia. The selection of case companies included three business consulting companies and four industrial companies. The aim of this qualitative study was to understand and clarify how business marketing exploits digital marketing methods as a part of the chosen business marketing strategy under emerging markets’ special conditions. This objective was divided in three research questions: 1) How the chosen marketing strategy reflects in the business marketing process? 2) How digital marketing communication contributes to business marketing? 3) How are the emerging markets’ characteristics reflected in the business marketing process? The main research findings indicate that digital business-to-business marketing communications can be useful and effective. Moreover, business DMC can be defined and structured in a reasonable way. The company's prevalent marketing paradigm and the chosen marketing strategy reflect in the business marketing process, and in utilizing digital marketing communications. The assumption that emerging markets set an environment with special characteristics for business marketing was supported by the study. However, the business environmental aspects were not considerably disturbing digital B2B marketing, but making it even more reasonable to harness in Russia.

Studies on chemoenzymatic synthesis: Lipase-catalyzed acylation in multistep organic synthesis

In this thesis, biocatalysis is defined as the science of using enzymes as catalysts in organic synthesis. Environmental aspects and the continuously expanding repertoire of available enzymes have firmly established biocatalysis as a prominent means of chemo-, regio- and stereoselective synthesis. Yet, no single methodology can solve all the challenges faced by a synthetic chemist. Therefore, the knowledge and the skills to combine different synthetic methods are relevant. Lipases are highly useful enzymes in organic synthesis. In this thesis, an effort is being made to form a coherent picture of when and how can lipases be incorporated into nonenzymatic synthesis. This is attempted both in the literature review and in the discussion of the results presented in the original publications contained in the thesis. In addition to lipases, oxynitrilases were also used in the work. The experimental part of the thesis comprises of the results reported in four peer-reviewed publications and one manuscript. Selected amines, amino acids and sugar-derived cyanohydrins or their acylated derivatives were each prepared in enantio- or diastereomerically enriched form. Where applicable, attempts were made to combine the enzymatic reactions to other synthetic steps either by the application of completely separate sequential reactions with isolated intermediates (kinetic and functional kinetic resolution of amines), simultaneously occurring reactions without intermediate isolation (dynamic kinetic resolution of amino acid esters) or sequential reactions but without isolating the intermediates (hydrocyanation of sugar aldehydes with subsequent diastereoresolution). In all cases, lipase-catalyzed acylation was the key step by which stereoselectivity was achieved. Lipase from Burkholderia cepacia was a highly selective enzyme with each substrate category, but careful selection of the acyl donor and the solvent was important as well.

Ympäristöjärjestelmän rakentaminen ja sen haasteet Lappeenrannan teknillisellä yliopistolla

Lappeenrannan teknilliselle yliopistolle on rakennettu ISO14001-mukaista ympäristöjärjestelmää. Tässä diplomityössä tarkastellaan rakentamisen vaiheita sekä etsitään ratkaisuja rakentamisen aikana ilmeneviin haasteisiin. Teoriaosassa keskitytään ympäristö- ja kestävän kehityksen toimintaan yliopistoissa sekä ISO14001-standardin mukaisiin ympäristöjärjestelmiin. Ympäristöjärjestelmää rakennettaessa luodaan ympäristöpolitiikka sekä arvioidaan ja valitaan yliopiston merkittävimmät ympäristönäkökohdat. Näkökohdille luodaan päämäärät, tavoitteet ja ohjelmat. Lisäksi työssä tarkastellaan lakisääteisiä vaatimuksia ja luodaan menetelmiä dokumentointiin, koulutukseen, poikkeamien havainnointiin ja sisäiseen auditointiin. Yliopistolle on mahdollista rakentaa toimiva ympäristöjärjestelmä, mutta se vaatii aika- ja taloudellisten resurssien lisäksi myös vahvan tuen ylimmältä johdolta sekä halua ajaa muutos organisaatioon.
