Bysanttilaisten ja Akhaian ruhtinaskunnan väliset sotatoimet vuosina 1259-83 : Tapaustutkimus myöhäis-bysanttilaisesta sodankäynnistä

In my master thesis I analyse Byzantine warfare in the late period of the empire. I use military operations between Byzantines and crusader Principality of Achaia (1259–83) as a case study. Byzantine strategy was based (in “oriental manner”) on using ambushes, diplomacy, surprise attacks, deception etc. Open field battles that were risky in comparison with their benefits were usually avoided, but the Byzantines were sometimes forced to seek open encounter because their limited ability to keep strong armies in field for long periods of time. Foreign mercenaries had important place in Byzantine armies and they could simply change sides if their paymasters ran out of resources. The use of mercenaries with short contracts made it possible that the composition of an army was flexible but on the other hand heterogeneous – in result Byzantine armies were sometimes ineffective and prone to confusion. In open field battles Byzantines used formation that was made out from several lines placed one after another. This formation was especially suitable for cavalry battles. Byzantines might have also used other kinds of formations. The Byzantines were not considered equal to Latins in close combat. West-Europeans saw mainly horse archers and Latin mercenaries on Byzantine service as threats to themselves in battle. The legitimacy of rulers surrounding the Aegean sea was weak and in many cases political intrigues and personal relationships can have resolved the battles. Especially in sieges the loyalty of population was decisive. In sieges the Byzantines used plenty of siege machines and archers. This made fast conquests possible, but it was expensive. The Byzantines protected their frontiers by building castles. Military operations against the Principality of Achaia were mostly small scale raids following an intensive beginning. Byzantine raids were mostly made by privateers and mountaineers. This does not fit to the traditional picture that warfare belonged to the imperial professional army. It’s unlikely that military operations in war against the Principality of Achaia caused great demographic or economic catastrophe and some regions in the warzone might even have flourished. On the other hand people started to concentrate into villages which (with growing risks for trade) probably caused disturbance in economic development and in result birth rates might have decreased. Both sides of war sought to exchange their prisoners of war. These were treated according to conventional manners that were accepted by both sides. It was possible to sell prisoners, especially women and children, to slavery, but the scale of this trade does not seem to be great in military operations treated in this theses.

At a Crossroad: Immigration Reform and American Unionism

"Since the founding days of the Republic, the relationship between American unionism and mass immigration has been contentious. No issue has caused the labor movement more agony and irony. It is no surprise, therefore, that throughout its history the American labor movement has sought to influence U.S. immigration policy."

Kirkko, Kekkonen ja kommunismi poliittisina kriisivuosina 1958-1962

This study explores the relationship of the Evangelical Lutheran Church of Finland to communism and political power during the period of crises in Finnish foreign relations with the Soviet Union from 1958 to 1962. During this period the USSR repeatedly interfered in Finland´s domestic affairs and limited her foreign political freedom of action. The research subjects for this dissertation are the bishops of the Church of Finland and the newspaper Kotimaa, which can be regarded as the unofficial organ of the church at the time. A typical characteristic of the Church of Finland from the beginning of the twentieth century was patriotism. During the interwar years the church was strongly anti-communist and against the Soviet Union. This tendency was also evident during the Second World War. After the war the Finnish Church feared that the rise of the extreme left would jeopardize its position. The church, however, succeeded in maintaining its status as a state church throughout the critical years immediately following the war. This study indicates that, although the manner of expression altered, the political attitude of the church did not substantially change during the postwar period. In the late 1950s and early 1960s the church was still patriotic and fear of the extreme left was also evident among the leaders of the church. The victory of the Finnish People's Democratic League in the general election of 1958 was an unwelcome surprise to the church. This generated fear in the church that, with Soviet support, the Finnish communists might return to governmental power and the nation could become a people's democracy. Accordingly, the church tried to encourage other parties to set aside their disagreements and act together against the extreme left throughout the period under study. The main characteristics of the church´s political agenda during this period of crisis were to support the Finnish foreign policy led by the president of the republic, Urho Kekkonen, and to resist Finnish communism. The attitude of Finnish bishops and the newspaper Kotimaa to the Cold War in general was generally in agreement with the majority of western Christians. They feared communism, were afraid of the USSR, but supported peaceful co-existence because they did not want an open conflict with the Soviets. Because of uncertainties in Finland's international position the Finnish Church regarded it as necessary to support the Finnish policy of friendship towards the USSR. The Finnish Church considerer it unwise to openly criticize the Soviet Union, tried resist the spread of communism in Finnish domestic policy. This period of foreign policy crises was principally seen by the church as a time when there was a need to strengthen Finland's unstable national position.

Not all corporate tax avoiders will be snared by new rules

Hockey’s budget announcement of two major tax integrity measures was flagged before the budget was handed down, but even that came as no surprise. Integrity, or lack thereof, in our tax system is a hot topic and an easy target for a Treasurer looking to sell a federal budget. The first of the proposed changes is to our GST regime. No-one likes hearing that they will be paying more tax. But, the charging of GST on supplies of digital products and services in Australia by an off-shore supplier will at least make sense to the general public. With the inherent unfairness in the current system and a revenue raising prediction of A$350 million over the next four years, most are likely to accept the logic of such a measure. The second of the proposed changes are new laws to be included in Australia’s general anti-avoidance provision. New laws, which will apply from 1 January 2016, are aimed at multinational companies engaged in aggressive tax practices. The proposed anti-avoidance law is designed to stop multinationals that artificially avoid a taxable presence in Australia. It is difficult to see how this strategy of addressing specific behaviour through what is considered a general provision will work. And, it is these changes that are already causing confusion.

Saving Indigenous nurses and midwives from historical oblivion

Learning about the Indigenous women who had worked between 1950-2005 was a surprise to me. This area of under researched Australian history became a passion which I've continued to explore and, in recent years. have extended. It's a challenging field. with issues familiar to many historians. There may be many documentary records about Indigenous nurses, hidden in publicly accessible archives and collections, but individuals may not easily be identified as Indigenous. Another enormous challenge is to question widely-held assumptions. Historically, Aboriginal people have been positioned within a deficit model and cast as recipients of health care. So it's assumed that Indigenous people did not deliver care in any way. were not part of formal training schemes, or were not in paid employment. More evidence is emerging that counters those assumptions. Aboriginal women have worked as nurses and midwives within Australia as far back as the 1890s and, who knows, perhaps earlier. Their contribution is a hidden but significant element in Indigenous and Australian history

Puolustuskykyinen valtio vai Ruotsin hälytyskello? : Suomen sotilasstrateginen asema kylmän sodan alkuvuosien asiantuntija-arvioissa

The doctoral thesis deals with Finnish and foreign expert s analyses of Finland s military strategic position and defence capability, dating back to the early years of the Cold War. Finland s military high command prepared assessments of the country s strategic position and of the capability of the Defence Forces as grounds for defence planning. Since Finland was located on the Cold War dividing line, the foreign powers were also monitoring the development of Finland s situation. The research carried out had access to the armed forces internal assessments, as well as to analyses prepared by the military intelligence services of Sweden, Britain and the United States. One of the working hypotheses was that after the WWII the ability military leadership to estimate the security political needs of the country and the organisation of its defence was severely weakened so that the dangers of the international development were not perceived and the gradual erosion of defence capability was partly unnoticed. This hypothesis proved to be wrong. Even if the Finnish military intelligence was much weaker than during the war, it was able to provide the military leadership with information of the international military development for the most part. The military leadership was also fully aware of the weakening of the defence capability of the country. They faced the difficult task of making the country s political leadership, i.e. President Paasikivi and the government, also understand the gravity of the situation. Only in the last years of his term in office Paasikivi started to believe the warnings of the military. According to another hypothesis, outside observers considered the Finnish armed forces to primarily act as reinforcements for the Soviet Red Army, and they believed that, in the event of a full-scale war, the Finns would not have been able or even willing to resist a Soviet invasion of Sweden and Norway through Finland. The study confirmed that this was approximately the view the Swedes, the British and the Americans had of the Finnish forces. Western and Swedish intelligence assessments did not show confidence in Finland s defence ability and the country was regarded almost as a Soviet satellite. Finland s strategic position was, however, considered slightly different from that of the Soviet-occupied Eastern European countries. Finland had been forced to become part of the Soviet sphere of interest and security system and this was sealed by the Finno-Soviet Treaty of Friendship, Cooperation, and Mutual Assistance in 1948. Finland had little importance to the military interests of the Western powers. In Sweden s defence planning, however, Finland played a significant role as an alarm bell of a possible Soviet surprise attack, as well as defensive frontline and buffer zone.

How Do Different Types of Investors React to New Financial Statement Information?

The study contributes to our understanding of the forces that drive the stock market by investigating how different types of investors react to new financial statement information. Using the extremely comprehensive official register of share holdings in Finland, we find that the majority of investors are more probable to sell (buy) stocks in a company after a positive (negative) earnings surprise, and show a bias towards buying after the disclosure of new financial statement information. Large investors, on the other hand, show behavior opposite to that of the majority of investors in the market. Further, foreign investors show behavior similar to that of domestic investors. We suggest investor overconfidence and asymmetric information as possible explanations for the documented behavior.

Koti keskellä kaupunkia : Keskusta lapsiperheen asuinalueena, esimerkkeinä Tukholma ja Helsinki

Families with children have traditionally moved to suburbs. In the last 20 years a modest counter process has however been recognized. Families with an urban lifestyle stay in the city centres. This study looks at the phenomenon through two cases, Stockholm and Helsinki. In the first case it has already been observed that the city centre has grown in popularity among families with children. Therefore it serves as a basis for the study and as well as a point of comparison. Stockholm’s city centre is expanding as new neighbourhoods have been built and are being planned. In the city centre of Helsinki the building of two large neighbourhoods for 30 000 inhabitants will start in a few years. The first aim of the study is to look closer at what has really happened in the city centre of Stockholm, why families choose to live there with their children and how the City of Stockholm has reacted to the change. The main sources of information are secondary sources, statistics and interviews with planners, politicians and experts in the field. The main object is to look at the situation in the city centre of Helsinki. Can a preference for urban residential environments be observed in Helsinki? What are the reasons for a family to choose the city centre as a living place? How does the everyday life of a family in the city centre appear? How are these families taken into account in the planning of the city? The main sources of information here are statistics, interviews with dwellers in the neighbourhood Kruununhaka and interviews with planners. In Stockholm the birth rate has grown constantly during the 2000s and is highest in the city centre. Some of the families still move elsewhere, but many of them do not. One of the most important reasons for living in the city centre is short working distances which give working parents more time with their children. Another reason is a preference of an urban, active lifestyle. Families prefer to live close to everything, childcare, schools, shops and entertainments. The popularity of the city centre among families with children has taken politicians and planners by surprise. Helsinki has not experienced a baby boom like Stockholm. However the negative changes in the birth rate have been more modest in the central areas than in the suburbs. Statistics show, that many families move away from the city centre as the children grow. Families who stay in the city centre especially appreciate closeness to public and private services and good public transportation which means that they are not dependent on using the car. Further they find that the city centre has a tolerant climate and is a safe and beautiful place to live in. The families enjoy the social life of the neighbourhood and feel that it makes a good climate to raise children in. However they are concerned with traffic safety and the lack of stimulus in the playgrounds of the neighbourhood parks. Two large neighbourhoods with homes for about 30 000 inhabitants are now planned in the former Port Districts in the city centre of Helsinki. The other one, Jätkäsaari has been planned to become an attractive alternative for families with children. Traffic safety has been one of the main objects for the planning. The other, Kalasatama, has been planned to attract all groups in society.

Divergencies of Perception : The Possibilities of Merleau-Pontian Phenomenology in Analyses of Contemporary Art

Maurice Merleau-Ponty (1908-1961) has been known as the philosopher of painting. His interest in the theory of perception intertwined with the questions concerning the artist s perception, the experience of an artwork and the possible interpretations of the artwork. For him, aesthetics was not a sub-field of philosophy, and art was not simply a subject matter for the aesthetic experience, but a form of thinking. This study proposes an opening for a dialogue between Merleau-Pontian phenomenology and contemporary art. The thesis examines his phenomenology through certain works of contemporary art and presents readings of these artworks through his phenomenology. The thesis both shows the potentiality of a method, but also engages in the critical task of finding the possible limitations of his approach. The first part lays out the methodological and conceptual points of departure of Merleau-Ponty s phenomenological approach to perception as well as the features that determined his discussion on encountering art. Merleau-Ponty referred to the experience of perceiving art using the notion of seeing with (voir selon). He stressed a correlative reciprocity described in Eye and Mind (1961) as the switching of the roles of the visible and the painter. The choice of artworks is motivated by certain restrictions in the phenomenological readings of visual arts. The examined works include paintings by Tiina Mielonen, a photographic work by Christian Mayer, a film by Douglas Gordon and Philippe Parreno, and an installation by Monika Sosnowska. These works resonate with, and challenge, his phenomenological approach. The chapters with case studies take up different themes that are central to Merleau-Ponty s phenomenology: space, movement, time, and touch. All of the themes are interlinked with the examined artworks. There are also topics that reappear in the thesis, such as the notion of écart and the question of encountering the other. As Merleau-Ponty argued, the sphere of art has a particular capability to address our being in the world. The thesis presents an interpretation that emphasises the notion of écart, which refers to an experience of divergence or dispossession. The sudden dissociation, surprise or rupture that is needed in order for a meeting between the spectator and the artwork, or between two persons, to be possible. Further, the thesis suggests that through artworks it is possible to take into consideration the écart, the divergence, that defines our subjectivity.

Features in visual search combine linearly

Single features such as line orientation and length are known to guide visual search, but relatively little is known about how multiple features combine in search. To address this question, we investigated how search for targets differing in multiple features ( intensity, length, orientation) from the distracters is related to searches for targets differing in each of the individual features. We tested race models (based on reaction times) and coactivation models ( based on reciprocal of reaction times) for their ability to predict multiple feature searches. Multiple feature searches were best accounted for by a co-activation model in which feature information combined linearly (r = 0.95). This result agrees with the classic finding that these features are separable i.e., subjective dissimilarity ratings sum linearly. We then replicated the classical finding that the length and width of a rectangle are integral features-in other words, they combine nonlinearly in visual search. However, to our surprise, upon including aspect ratio as an additional feature, length and width combined linearly and this model outperformed all other models. Thus, length and width of a rectangle became separable when considered together with aspect ratio. This finding predicts that searches involving shapes with identical aspect ratio should be more difficult than searches where shapes differ in aspect ratio. We confirmed this prediction on a variety of shapes. We conclude that features in visual search co-activate linearly and demonstrate for the first time that aspect ratio is a novel feature that guides visual search.

Flowering in British Lemna: A rare, cyclic or simply overlooked phenomenon?

It is largely presumed that reproduction in British Lemna, as in other British Lemnaceae, is almost entirely asexual, with new daughter fronds being produced from the side pouches of older mother fronds. Sexual reproduction is considered to be a rather rare event or even absent and because of this rarity the sexual features of Lemna, such as anthers and fruit, are often considered to be of little taxonomic value. It was with some surprise, therefore, that widespread flowering was observed in all British Lemna during the summer of 1995. Initial observations in Shropshire during June recorded flowers in minor and trisulca, with fruit production in trisulca. L.gibba, minor and minuta were noted as being in flower on several occasions in Kent, during July and August, probably fruit production occurring in both species. To what extent these events are truly representative of the sexual reproduction rate of British Lemna on a year-to-year basis, or simply reflect the unusually high summer temperatures of 1995, is unclear.

Plankton associated with medusae of the freshwater jellyfish Craspedacusta sowerbyi (Lankester) in a Thames backwater

Samples of plankton were taken from Broom Water in August 1997 after a sighting of medusae on 11th August. Broom Water is about 8 m wide, and extends 250 m from the main channel of the Thames, above the weir at Teddington. On 11th August medusae were so abundant that it was possible to collect 20 in ten minutes. They were rising to the surface in bright sunlight, then sinking slowly down through the water. Examination of a medusa's tentacles under a microscope revealed the presence of a commensal protozoan, a ciliate Trichodina pediculus. Over 20 species of phytoplankton were found in Broom Water. Most of the species are common and widespread, but it was a surprise to find Errerella bornhemiensis with its characteristic pyramidal colonies, which is a relatively rare species. Zooplankters in Broom Water consisted of Rotifera and Crustacea. Zooplankton is the main food of Craspedacusta and it was found that the crustaceans but not the rotifers did undergo significant changes during the period 11-19th August. The major changes were a big increase in the percentage of cyclopoids, and a marked decrease in Bosmina. This could be because the delicate cuticle of Bosmina is much more susceptible to the stinging cells of the medusae compared with the tougher exoskeleton of the cyclopoid.

Separações conjugais em datas comemorativas

Visando apontar as vicissitudes que possam estar relacionadas ao fato de alguns rompimentos conjugais ocorrerem em datas comemorativas foi produzida a dissertação. O tema surgiu em pesquisas sobre separação conjugal e guarda de filhos do Instituto de Psicologia da Universidade do Estado do Rio de Janeiro, nas quais se observou que as dissoluções que ocorreram nas datas festivas eram relevantes. Foram desenvolvidas análises bibliográficas sobre casamento, dissolução da conjugalidade, comemorações, memórias e rituais. Devido à interdisciplinaridade da temática realizou-se estudos em Psicologia, Antropologia, Direito, História e Sociologia. Pretendeu-se verificar quais os sentidos atribuídos pelos ex-cônjuges à data comemorativa na qual ocorreu a separação. Buscou-se constatar se houve alteração ou reconfiguração do significado das datas após o rompimento e visou-se apresentar reflexões que possam auxiliar a prática clínica e jurídica, mediante a atuação do profissional psicólogo nas questões tangentes à separação conjugal. A metodologia utilizada foi de História de Oral História de vida. Foram entrevistados quatro sujeitos, um rapaz que tomou a iniciativa no seu aniversário, uma moça que anunciou a decisão no aniversário de vinte seis anos de casamento, uma mulher que recebeu a notícia no Natal e um homem que foi comunicado no Ano Novo. Todos são do Estado do Rio de Janeiro e de classe média. A partir do discurso foi realizada a análise qualitativa dos dados, classificando-se as respostas em categorias essenciais à pesquisa. Como resultados verificou-se, no que se refere às datas comemorativas, que os entrevistados vivenciaram esses momentos como se estas possuíssem algo de mágico. Como se nestas épocas todos os problemas pudessem ser colocados de lado e tréguas pudessem ser feitas. Entretanto, os relatos mostraram que a tal mágica não ocorreu, as dificuldades continuaram expostas e, pelo contrário, o clima do evento evidenciou as convergências ficando difícil progredir como se nada estivesse acontecendo. Os sujeitos que tiveram a iniciativa em terminar com o relacionamento afirmaram que as datas das bodas de casamento e o aniversário natalício deram força e coragem que não tinham tido até aquele momento. Este ato favoreceu a sensação de realização e conquista que, no entanto, vinham misturada de dor, frustração e mágoa. Os sujeitos que receberam o comunicado da decisão do rompimento do casamento no Natal e no Réveillon reconheceram que a noticia configurou-se numa surpresa impactante, ao ponto de provocar silêncio. Identificou-se que não houve reconfiguração nos sentidos atribuídos às datas comemorativas, ao contrário o rompimento nestes eventos sociais fortaleceram o acontecimento. No entanto, foi possível perceber uma adição ao calendário oficial. O Natal, o Réveillon, as bodas e o aniversário é, também, o dia do rompimento conjugal. Soma-se marcos e fortifica-se o evento na memória dos sujeitos que vivenciaram estas histórias. Dentre as contribuições para a prática da Psicologia Jurídica e da clínica evidenciou-se que estes profissionais devem estar atentos ao caráter cíclico das festividades que estão nos calendários, configurando-se em momentos de transição, de inícios e fins.

Escritas à deriva: testemunhos efêmeros sobre os tempos da escola nas comunidades do Orkut

Se na tentativa de evocar o passado escolar, abrirmos com disposição as páginas das redes sociais virtuais, poderemos também nos surpreender com as memórias dos usuários encontradas nas comunidades do Orkut; nas tramas das histórias escolares, os scraps digitais exibem os relatos dos ex-alunos, numa verdadeira exibição do eu. Este estudo traz para a discussão os posts encontrados nas comunidades do Orkut do Colégio Militar do Rio de Janeiro, do Colégio de São Bento do Rio de Janeiro e do Colégio Marista São José do Rio de Janeiro, procurando dar visibilidade a essas escritas autobiográficas virtuais sobre a vida escolar como fontes para a história da Educação. Como esses usuários narram as suas histórias escolares? Quais os relatos mais frequentes? Estas questões me instigam a pensar que o registro das experiências escolares possibilita ao sujeito desnudar-se. No tempo das tecnologias digitais, o usuário move-se sobre teclados, telas, deixando registros de uma vida, que são examinados pelos moderadores. Mas quem são estes sujeitos nas comunidades escolares? Será que eles cumprem os mesmos papéis desempenhados pelos editores? As escritas memorialistas comandam, imperativamente, novas relações com a escrita; essas narrativas não se esgotam numa tipologia textual persuasiva; observam-se laços de ideias e afetos, aproximando os ex-alunos dessas redes sociais virtuais. Quais são os temas mais recorrentes encontrados neste espaço virtual? Estas postagens constituem elos do tecido das lembranças dos sujeitos que não se intimidam em contar as suas histórias nesses novos suportes de escrita. Talvez, a saudade e a solidão busquem acolhimento e companhia nos cliques dos usuários, remetendo-os aos acontecimentos passados; os ex-alunos compartilham experiências, sentimentos e saberes, borrando fronteiras entre o público e o privado; nesse sentido, percebe-se que essas escritas autobiográficas nas comunidades escolares do Orkut também constroem esses sujeitos no suporte digital. Assim, este trabalho procura ampliar a discussão sobre os lugares de memórias da escolarização, buscando contribuir para os estudos da história da Educação.
