Potential impact of the global climate changes on the spatial distribution of areas of risk for the occurrence of eucalyptus rust in Brazil

Rust, caused by Puccinia psidii, is one of the most important diseases affecting eucalyptus in Brazil. This pathogen causes disease in mini-clonal garden and in young plants in the field, especially in leaves and juvenile shoots. Favorable climate conditions for infection by this pathogen in eucalyptus include temperature between 18 and 25 ºC, together with at least 6-hour leaf wetness periods, for 5 to 7 consecutive days. Considering the interaction between the environment and the pathogen, this study aimed to evaluate the potential impact of global climate changes on the spatial distribution of areas of risk for the occurrence of eucalyptus rust in Brazil. Thus, monthly maps of the areas of risk for the occurrence of this disease were elaborated, considering the current climate conditions, based on a historic series between 1961 and 1990, and the future scenarios A2 and B2, predicted by IPCC. The climate conditions were classified into three categories, according to the potential risk for the disease occurrence, considering temperature (T) and air relative humidity (RH): i) high risk (18 < T < 25 ºC and RH > 90%); ii) medium risk (18 < T < 25 ºC and RH < 90%; T< 18 or T > 25 ºC and RH > 90%); and iii) low risk (T < 18 or T > 25 ºC and RH < 90%). Data about the future climate scenarios were supplied by GCM Change Fields. In this study, the simulation model Hadley Centers for Climate Prediction and Research (HadCm3) was adopted, using the software Idrisi 32. The obtained results led to the conclusion that there will be a reduction in the area favorable to eucalyptus rust occurrence, and such a reduction will be gradual for the decades of 2020, 2050 and 2080 but more marked in scenario A2 than in B2. However, it is important to point out that extensive areas will still be favorable to the disease development, especially in the coldest months of the year, i.e., June and July. Therefore, the zoning of areas and periods of higher occurrence risk, considering the global climate changes, becomes important knowledge for the elaboration of predicting models and an alert for the integrated management of this disease.

The demand for global student talent: Capitalizing on the value of university-industry collaboration

The university sector in Europe has invested money and effort into the internationalization of higher education. The benefits of internationalizing higher education are fuelled by changing global values, choices and practices. However, arguments that serve the internationalization of higher education tend to stress either local organizational or individual interests; seldom do they emphasize the societal benefits. This dissertation investigates how collaboration between university and industry facilitates a shift in thinking about attracting and retaining global student talent, in terms of co-creating solutions to benefit the development of our knowledge society. The macro-structures of the higher education sector have the tendency to overemphasize quantitative goals to improve performance verifiability. Recruitment of international student talent is thereby turned into a mere supply issue. A mind shift is needed to rethink the efficacy of the higher education sector with regard to retaining foreign student talent as a means of contributing to society’s stock of knowledge and through that to economic growth. This thesis argues that academic as well as industrial understanding of the value of university-industry collaboration might then move beyond the current narrow expectations and perceptions of the university’s contribution to society’s innovation systems. This mind shift is needed to encourage and generate creative opportunities for university-industry partnerships to develop sustainable solutions for successful recruitment of foreign student talent, and thereby to maximize the wealth-creating potential of global student talent recruitment. This thesis demonstrates through the use of interpretive and participatory methods, how it is possible to reveal new and important insights into university-industry partnering for enhancing attraction and retention of global student talent. It accomplishes this by expressly pointing out the central role of human collaborative experiencing and learning. The narratives presented take the reader into a Finnish and Dutch universityindustry partnering environment to reflect on the relationship between the local universities of technology and their operational surroundings, a relationship that is set in a context of local and global entanglements and challenges.

The Global War on Terrorism in the Horn of Africa

Ever since Siad Barre’s regime was toppled in the beginning of the 1990’s Somalia has been without an effective central government. As a result Somalia has remained in an anarchic condition of state collapse for nearly two decades. This anarchy has often been put forward as a potential breeding ground for terrorism. As a response to this threat the United States has undertaken several policies, initiatives, and operations in the Horn of Africa generally and in Somalia specifically. In this descriptive study a twofold analysis has been undertaken. First, conditions in present day Somalia as well as Somali history have been analyzed to evaluate the potential Somalia holds as a terrorist base of operations or a recruiting- or staging area. Second, US strategies and actions have been analyzed to evaluate the adequacy of the US response to the threat Somalia poses in terms of terrorism. Material for the analyses have been derived from anthropological, political, and security studies dealing with Somalia. This material has been augmented by a wide range of news coverage, western and non-western. Certain different US policy documents from different levels have been chosen to represent US strategies for the Global War on Terrorism. Because Somali social institutions, such as the clan system, hold great weight in Somali society, Somalia is a difficult area of operations for terrorist networks. In addition the changing nature of Somali alliances and the tangled webs of conflict that characterize present day Somalia aggravate the difficulties that foreign terrorist networks would encounter in Somalia, would they choose to try to utilize it in any great extent. The US has taken potential terrorism threats in Africa and specifically Somalia very seriously. US actions in Somalia have mainly focused on apprehending or neutralizing terror suspects. Such policies, coupled with backing the Ethiopian invasion of Somalia may have actually turned out increasing Somalia’s terror potential.

Roles of leadership in complex environments : Enhancing Knowledge Flows in Organisational Constellations through Practice-Based Innovation Processes

Global challenges, complexity and continuous uncertainty demand development of leadership approaches, employees and multi-organisation constellations. Current leadership theories do not sufficiently address the needs of complex business environments. First of all, before successful leadership models can be applied in practice, leadership needs to shift from the industrial age to the knowledge era. Many leadership models still view leadership solely through the perspective of linear process thinking. In addition, there is not enough knowledge or experience in applying these newer models in practice. Leadership theories continue to be based on the assumption that leaders possess or have access to all the relevant knowledge and capabilities to decide future directions without external advice. In many companies, however, the workforce consists of skilled professionals whose work and related interfaces are so challenging that the leaders cannot grasp all the linked viewpoints and cross-impacts alone. One of the main objectives of this study is to understand how to support participants in organisations and their stakeholders to, through practice-based innovation processes, confront various environments. Another aim is to find effective ways of recognising and reacting to diverse contexts, so companies and other stakeholders are better able to link to knowledge flows and shared value creation processes in advancing joint value to their customers. The main research question of this dissertation is, then, to seek understanding of how to enhance leadership in complex environments. The dissertation can, on the whole, be characterised as a qualitative multiple-case study. The research questions and objectives were investigated through six studies published in international scientific journals. The main methods applied were interviews, action research and a survey. The empirical focus was on Finnish companies, and the research questions were examined in various organisations at the top levels (leaders and managers) and bottom levels (employees) in the context of collaboration between organisations and cooperation between case companies and their client organisations. However, the emphasis of the analysis is the internal and external aspects of organisations, which are conducted in practice-based innovation processes. The results of this study suggest that the Cynefin framework, complexity leadership theory and transformational leadership represent theoretical models applicable to developing leadership through practice-based innovation. In and of themselves, they all support confronting contemporary challenges, but an implementable method for organisations may be constructed by assimilating them into practice-based innovation processes. Recognition of diverse environments, their various contexts and roles in the activities and collaboration of organisations and their interest groups is ever-more important to achieving better interaction in which a strategic or formal status may be bypassed. In innovation processes, it is not necessarily the leader who is in possession of the essential knowledge; thus, it is the role of leadership to offer methods and arenas where different actors may generate advances. Enabling and supporting continuous interaction and integrated knowledge flows is of crucial importance, to achieve emergence of innovations in the activities of organisations and various forms of collaboration. The main contribution of this dissertation relates to applying these new conceptual models in practice. Empirical evidence on the relevance of different leadership roles in practice-based innovation processes in Finnish companies is another valuable contribution. Finally, the dissertation sheds light on the significance of combining complexity science with leadership and innovation theories in research.

“Why share in uncertain conditions?” Factors of individual level knowledge sharing in offshoring cases

The objective of this Master’s Thesis was to research factors influencing and enhancing individual level knowledge sharing in offshore projects which often involve uncertainty of the knowledge provider’s own future. The purpose was to understand why individuals are willing to share their knowledge under these kinds of circumstances. In addition the goal was to identify obstacles to interpersonal knowledge sharing in order to understand how to mitigate their influence. The research was conducted as a qualitative multiple case study in a global IT company, and the data was gathered using semi-structured personal theme interviews within two different offshore projects. In order to a gain a wider perspective on the matter, some management representatives were interviewed as well. Data was analysed with the inductive content analysis method. Results of the study indicate that individuals are willing to share their knowledge despite of uncertainty if they are motivated, if they are provided with opportunities to do so, and if they have skills, competence and experience to share their knowledge. A strong knowledge sharing culture in the organization or team also works as a strong incentive for individual level knowledge sharing. The findings suggest that even under uncertain conditions it is possible to encourage people to share their knowledge if uncertainty can be decreased to a bearable level, a robust and personal connection and relationship between the knowledge provider and acquirer can be created and suitable opportunities for knowledge sharing are provided. In addition, based on the results the support and commitment of management and HR in addition to favourable environmental circumstances play an essential role in building a bridge between the knowledge provider and acquirer in order to create a virtual environment and space for knowledge sharing: Ba.

Co-creating value with customers as a new approach of entering new market

Global trends associated with development of information technology, globalization, industrial and economic changes are influencing on company and customer domains and thus transforming company-customer relationship. The company centric paradigm with a strong product focus shifts to a customer oriented one with a strong emphasis on customer collaboration. As a result, the customer role changes from a passive observer to an active player. Moreover, global trends contribute to transformation of competitive environment making it tougher and simplifying an access to resources previously considered as unique. All that factors push the companies towards cooperation with customers in order to identify unarticulated needs and finding the best possible solution to existing customer problems. The Master’s Thesis is done for Outotec (Lappeenranta) which considers extension of dewatering business in Russian coal market. Research aims to identify key features of coal preparation and dewatering of fine coal and tailings in Russian preparation plants; analyze the state of Russian coal market and evaluate market potential for Outotec dewatering solutions. The study has a qualitative nature and implements an action research methodology that involves both creation of knowledge and introduction of changes into the system. The base for taking actions is formed by theoretical framework that targets on describing company - customer interaction and has selected co-creation as the most appropriate method of customer involvement. The integration of co-creation approach into an action research cycle allows not only fulfilling the research objectives but also facilitates organizational learning and intraorganizational collaboration, assists in establishing customer contacts and making the first steps into the market, bringing new joint projects to the company and opening real business opportunities.

Tuotekustannuslaskennan nykytila ja kustannusseurannan kehittäminen mallimoottoriajattelun avulla

Tutkimuksen tarkoituksena on tutkia globaalin konsernin yhden liiketoimintayksikön tuotekustannuslaskennan nykytilaa. Lisäksi tutkimuksessa selvitetään, miten tuotekohtaista kustannusseurantaa voidaan kehittää mallimoottoriajatuksen avulla. Tutkimus on toteutettu laadullisena case-tutkimuksena yhden organisaation tietojen pohjalta. Teoriaosuuden lähdeaineistot koostuvat pääosin kustannuslaskennan ja -johtamisen perusteoksista ja tieteellisistä artikkeleista. Empiriaosuuden tiedot pohjautuvat haastatteluihin, tietojärjestelmiin ja tutustumiseen organisaatioon. Tutkimuksessa selvisi, että liiketoimintayksikkö ei tällä hetkellä seuraa tuotekohtaisia kustannuksia yksittäisten tuotteiden tasolla. Kustannusseuranta tapahtuu sen sijaan suurempien kokonaisuuksien keskimääräisten kustannuksien tasolla. Tuotekustannuslaskenta on toteutettu perinteiseksi menetelmäksi luokiteltavalla laskentatavalla, jossa välilliset kustannukset kohdistetaan yleiskustannuslisäprosenttien avulla. Tutkimuksen perusteella yleiskustannuksien kohdistamisperusteissa on havaittavissa viitteitä kustannuksien vääristymisestä. Tuotetason kustannuksien seurantaan kehitettiin mallimoottoriajatukseen pohjautuva kustannusmalli, jonka avulla seurataan tarkasti valikoitujen tuotteiden kustannuksien kehittymistä sekä kustannusrakennetta. Mallin avulla voidaan lisätä tuotetason kustannustietoisuutta liiketoimintayksikössä sekä tehdä havaintoja tuotekohtaisten kustannuksien kehityssuunnasta. Mallin kustannustietona käytetään olemassa olevan kustannuslaskentajärjestelmän tietoja. Tästä johtuen mallin kustannustiedoissa on havaittavissa myös viitteitä kustannuksien vääristymisestä.

Bebida mista com propriedade estimulante à base de água de coco e suco de caju clarificado

Na indústria de bebidas, uma alternativa para acrescentar valor nutricional ou simplesmente desenvolver novos sabores é a mistura de diferentes sucos de frutas na formulação de bebidas mistas. Este trabalho teve como objetivo o desenvolvimento de uma bebida à base de água de coco e suco de caju clarificado (cajuína), com adição de cafeína, conferindo-lhe propriedades estimulantes. Foram avaliadas cinco formulações, com diferentes proporções de cajuína, tendo sido padronizados previamente o pH, teor de sólidos solúveis e cafeína. As formulações foram submetidas à caracterização físico-química (pH, sólidos solúveis, acidez, açúcares redutores, não redutores e totais e vitamina C), análises microbiológicas e avaliação sensorial de aceitação (atributos de cor, sabor, avaliação global e intenção de compra). Todas as formulações em estudo apresentaram boa aceitação sensorial, não havendo diferença entre as médias dos atributos avaliados. Na intenção de compra, a formulação mais aceita foi ACC 20 (20% de cajuína e 80% de água de coco). A incorporação de vitamina C na bebida através da adição da cajuína foi mais evidente até a formulação ACC 20. Os resultados indicaram que a formulação ACC 20 foi a mais viável para elaboração da bebida mista. Todas as formulações apresentaram padrões microbiológicos satisfatórios.

Filmes e coberturas comestíveis compostas à base de amidos nativos e gelatina na conservação e aceitação sensorial de uvas Crimson

Filmes compostos de gelatina com amidos nativos de trigo, sorgo, batata e arroz foram produzidos separadamente e caracterizados quanto às propriedades físico-químicas (solubilidade em água e barreira ao vapor de água), físicas (espessura e opacidade) e mecânicas (resistência à tração e porcentagem de elongação na ruptura). As mesmas soluções filmogênicas foram preparadas e aplicadas em uvas Crimson para avaliação sensorial e acompanhamento da perda de massa durante 22 dias. As coberturas de sorgo e arroz foram as mais eficientes na extensão da vida útil (aumento de 10 dias). Entretanto, em relação aos atributos sensoriais, as uvas com cobertura de arroz não diferiram estatisticamente do controle, que apresentou as menores notas para os parâmetros de aparência global e intenção de compra. O filme de sorgo apresentou uma permeabilidade ao vapor de água de 5,40 g.mm.m-2.d.kPa, resistência à tração de 85,89 MPa, elongação de 6,61% e opacidade de 40%. Mesmo não apresentando os melhores valores de caracterização, como filme, tornou-se a melhor opção como cobertura. Na avaliação sensorial, as uvas cobertas obtiveram aceitação igual ou maior que o controle quanto à aparência global, brilho, cor e intenção de compra. Na degustação das uvas, nenhuma das coberturas exerceu influência significativa no aroma, sabor e textura, sendo aceitas pelo consumidor em todos os parâmetros.

Desenvolvimento de bebida mista à base de água de coco e suco de acerola

Levando-se em consideração o grande potencial de industrialização da água de coco e do suco de acerola e suas propriedades funcionais, o presente trabalho teve como objetivo elaborar uma bebida mista à base de água de coco e suco de acerola, na forma "pronto para beber", e avaliar sua estabilidade durante 180 dias de armazenamento à temperatura ambiente (28 ± 2 °C). Foram preparadas quatro formulações com duas proporções de suco de acerola (25 e 30%) e sólidos solúveis (10 e 12 °Brix), submetidas ao tratamento térmico a 90 °C durante 60 segundos e envasadas a quente em garrafas de vidro. As formulações foram submetidas à caracterização química e físico-química (pH, acidez, sólidos solúveis e vitamina C) e avaliação sensorial (cor, sabor e avaliação global). A formulação mais aceita foi avaliada através de análises químicas, físico-químicas, sensoriais e microbiológicas durante 180 dias de armazenamento. A bebida elaborada com 30% de suco de acerola e adicionada de sacarose até 12 °Brix obteve as maiores notas de aceitação para o sabor e avaliação global quando comparada às demais formulações estudadas. A bebida mista apresentou pH, acidez, sólidos solúveis e açúcares totais estáveis. Os conteúdos de vitamina C, antocianinas totais, açúcares redutores e cor variaram significativamente ao longo de 180 dias de armazenamento. A bebida formulada manteve estabilidade microbiológica. A avaliação sensorial mostrou que a bebida teve boa aceitação pelos provadores, principalmente durante os primeiros 90 dias de armazenamento.

Aceitabilidade de biscoitos e bolos à base de arroz com café extrusados

O objetivo deste trabalho foi avaliar a granulometria de farinha do trigo e de farinhas pré-cozidas por extrusão obtidas da mistura de arroz com pó de café (15 e 20%), bem como a aceitabilidade de biscoitos e bolos elaborados a partir da adição de 20 e 30% da farinha pré-cozida na mistura da massa (trigo). Os resultados obtidos mostraram que as farinhas extrusadas apresentaram maior granulometria que a farinha de trigo; à medida que se aumentou o percentual de farinha pré-cozida na mistura com o trigo, também aumentou a granulometria. Não houve diferença significativa entre as amostras tratadas com 15 e 20% de farinha pré-cozida quanto à preferência sensorial de aroma, textura, sabor e impressão global avaliados em bolos. Entretanto, os biscoitos elaborados com a farinha pré-cozida com 15% de pó de café na mistura com arroz apresentaram maior preferência para aroma e textura ao serem comparados com aqueles com 20%; a farinha pré-cozida de pó de café com arroz pode ser utilizada como ingrediente na mistura de bolos, biscoitos e outros produtos alimentícios em até 30%.

Khrushchev's Beau Geste: the Return of Porkkala and its Global Significance

The return of the Porkkala naval base, which was leased to the Soviet Union at the end of World War II was unexpectedly returned in early 1956, 42 years before the USSR's lease on the area was to expire. There is no commonly accepted reason, and therefore the purpose of this work is to study the possible motives behind the return of Porkkala. These seem to have been reflected in the new foreign policy after the death of Stalin, which went far beyond returning Porkkala to Finland. The Soviet Union's courting of the non-aligned powers during this time, into which category Finland was assigned, also seems to be more than coincidence. However, the greater events of 1956, and the fact that Porkkala is remembered almost exclusively in Finland may have conspired to trap the events around Porkkala into the smaller narrative of Finnish-Soviet relations and the rise of Kekkonen to the presidency, due in no small part to his presence in negotiating the return of Porkkala. However this does not negate the message that Porkkala was intended to broadcast the USSR's new approach to neutrality. Through primary and secondary sources, gleaned from archives in Finland, memoirs of people involved, and historical literature, this thesis hopes to broaden the view that Porkkala's main and only significance lay in the changes it brought to Finnish-Soviet relations.
