This study investigates the characteristics and attributes that private equity investors prefer when selecting target acquisitions. These characteristics are examined against a matched sample of firms subject to corporate acquisitions via tender/merger offer during 2000-2009, across seven countries: Australia, Canada, the United Kingdom, the USA, France, Germany and Sweden. We show that firm-specific characteristics are more influential in target selection than external or institutional variables. In particular, private equity targets exhibit lower stock volatility and long-term growth prospects, are larger, and have greater abnormal operating income relative to tender/merger offer target firms. Further, private equity bidders exhibit 'home bias', implying that familiarity motivates target selection. Institutional factors remain largely insignificant across all tests.

Dengue fever (DF) is a serious public health concern in many parts of the world. An increase in DF incidence has been observed globally over the past decades. Multiple factors including urbanisation, increased international travels and global climate change are thought to be responsible for increased DF. However, little research has been conducted in the Asia-Pacific region about the impact of these changes on dengue transmission. The overarching aim of this thesis is to explore the spatiotemporal pattern of DF transmission in the Asia-Pacific region and project the future risk of DF attributable to climate change. Annual data of DF outbreaks for sixteen countries in the Asia-Pacific region over the last fifty years were used in this study. The results show that the geographic range of DF in this region increased significantly over the study period. Thailand, Vietnam and Laos were identified as the highest risk areas and there was a southward expansion observed in the transmission pattern of DF which might have originated from Philippines or Thailand. Additionally, the detailed DF data were obtained and the space-time clustering of DF transmission was examined in Bangladesh. Monthly DF data were used for the entire country at the district level during 2000-2009. Dhaka district was identified as the most likely DF cluster in Bangladesh and several districts of the southern part of Bangladesh were identified as secondary clusters in the years 2000-2002. In order to examine the association between meteorological factors and DF transmission and to project the future risk of DF using different climate change scenarios, the climate-DF relationship was examined in Dhaka, Bangladesh. The results show that climate variability (particularly maximum temperature and relative humidity) was positively associated with DF transmission in Dhaka. The effects of climate variability were observed at a lag of four months which might help to potentially control and prevent DF outbreaks through effective vector management and community education. Based on the quantitative assessment of the climate-DF relationship, projected climate change will likely increase mosquito abundance and activity and DF in this area. Assuming a temperature increase of 3.3oC without any adaptation measures and significant changes in socio-economic conditions, the consequence will be devastating, with a projected annual increase of 16,030 cases in Dhaka, Bangladesh by the end of this century. Therefore, public health authorities need to be prepared for likely increase of DF transmission in this region. This study adds to the literature on the recent trends of DF and impacts of climate change on DF transmission. These findings may have significant public health implications for the control and prevention of DF, particularly in the Asia- Pacific region.

For the past decades reflection has been the buzzword of adult and higher education. Reflection is facilitated in many practices and there is abundant research on the issue. Despite the popularity of the concept, the reasons why bringing about reflection in educational practices is difficult remain unclear. The prevailing theories inform of the process in its ideal form. However, to a great extent, they fail to offer conceptual tools for understanding and working with the actualities of reflection. The aim of the doctoral thesis was to explore the challenges and prerequisites of reflection in order to theorize the nature of reflection. By the term reflection it is here referred to becoming aware of and questioning the assumptions that orient our thinking, feelings and actions. The doctoral thesis consists of five studies that approach these questions from different viewpoints and within different contexts. The methods involve both a philosophical and an empirical approach. This multifaceted approach embodies the aim of both gaining a more thorough grasp of the phenomenon and to develop the methodology of researching reflection. The theory building is based on conceptual analysis and rational reconstruction (see Davia 1998; Habermas 1979; Rorty1984) of Mezirow s (1981; 1991; 2000; 2009) theory of transformative learning. In order to explore the aspects which, based on the analysis, appeared insufficiently considered within Mezirow s theory, Damasio s (1994; 1999; 2003; 2010) theory on emotions and consciousness as well as Clausewitz s (1985) view on friction are used as complementary theories. Empirical analyses are used in dialogue with the theoretical, in order to challenge and refine the emerging theorization. Reflection is examined in three different contexts; regarding university teachers pedagogical growth, involuntarily childless women recovering from a life-event crisis, and soldiers preparing to act in chaotic situations of the battlefield as well as recovering from it. The choice of these contexts is based on Mezirow s notion of disorienting dilemma as a trigger for reflection. This notion indicates that reflection may more naturally emerge in association to life-event crises or other cumulative sets of instances, which bring our worldview and beliefs under question. Nevertheless, reflection is often being promoted in educational contexts in which the trigger conditions may not readily prevail. These contextual issues as well as the differences between the facilitated and non-facilitated contexts have not, however, been considered in detail within the research on reflection (or transformative learning). The doctoral thesis offers a new perspective into reflection which, as a further development on Mezirow s transformative learning theory, theorizes the nature of reflection. The developed theory explicates the prerequisites and challenges to reflection. The theory suggests that the challenges of reflection are fundamentally connected to the way the biological life-support system affects our thinking through emotions. While depicting the mechanisms that function as a counterforce to reflection, the developed theory also opens a perspective for considering possibilities for carrying out reflection, and suggests ways to locate and deal with the assumptions to be reflected on. The basic dynamic of the challenges to reflection was explicated by conceptually bridging the gap between Mezirow s and Damasio s theories, through exploring the connections between the meaning perspective and the biological functions of emotions. The concepts of comfort zone and edge-emotions were formed so as to depict the emotional orientation of our thinking, as part of the explanation of the nature of reflection.

Tutkielmassa tarkastellaan kahden etunimityypin yleistymistä ja suosionvaihtelua. Tutkittavat nimityypit ovat kak-sitavuiset ija-päätteiset naisennimet (kuten Eija, Maija ja Raija), joita tutkielmassa kutsutaan Aija-tyypiksi, ja kak-sitavuiset nja-päätteiset naisennimet (kuten Pinja, Ronja ja Tanja), joita kutsutaan Anja-tyypiksi. Tavoitteena on tutkia kahden naisennimityypin syntymistä ja suosiota. Mikä on nimien alkuperä ja onko uuden nimen mallina käytetty mahdollisesti toista, yleistä nimeä? Mitkä nimistä ovat yleistyneet ensimmäisinä ja mitkä nimet ovat jää-neet harvinaisiksi? Milloin ija- ja nja-päätteiset nimet ovat suosituimmillaan, ja miten nimityyppien suosiot ovat vaihdelleet? Tutkimuksen aineisto on saatu Väestörekisterikeskuksen tilastoista, jotka sisältävät tiedot vuonna 1965 elossa ol-leista ja sen jälkeen syntyneistä suomalaisista. Aineistoon on poimittu viisivuotiskausittain vuosilta 1870 1999 kaikki ija- ja nja-loppuiset nimet, jotka on annettu ensimmäisiksi etunimiksi suomenkielisille tytöille. Aineistoon kuuluu myös vastaavat tiedot yksittäisiltä vuosilta 2000 2009. Lisäksi työssä tukeudutaan monin paikoin Väestö-rekisterikeskuksen nimipalveluun, joka on Väestörekisterikeskuksen internetsivuilla toimiva hakupalvelu. Aineisto sisältää yhteensä 46 Aija-tyypin nimeä ja 66 Anja-tyypin nimeä. Työn tutkimusmetodi on kvantitatiivinen: etunimi-tyyppien yleistymistä selvitetään ja kuvataan taulukoiden ja kaavioiden avulla. Työssä hyödynnetään soveltuvin osin innovaatiotutkimuksen teorioita ja tilastotieteen menetelmiä. Sekä (K)+V+ija että (K)+V+nja ovat nimimuotteja. Niiden mukaan on helppo muodostaa uusia nimiä, jotka yleen-sä ongelmitta tunnistetaan (naisten)nimiksi. Alun perin nämä muotit on tunnettu lähinnä lempinimimuotteina, jotka todennäköisesti ovat alkujaan lainaa. Myöhemmin Aija- ja Anja-tyypin nimiä on alettu antaa myös virallisiksi ni-miksi, ja viimeistään 1900-luvun alusta lähtien tämän mallin mukaisilla nimillä on ollut kiistatta virallisen etuni-men asema. Tutkielmassa osoitetaan, että tutkittavat etunimityypit ovat kuuluneet etunimistöön jo 1800-luvun puolella. Monet Aija-tyypin nimet yleistyvät 1900-luvun alussa ja ovat yleisimmillään 1900-luvun puolivälissä. Suosionhuipun aikana ija-päätteisen nimen saa keskimäärin useampi kuin joka kymmenes tyttö. Anja-tyypillä ei ole yhtä selkeää suosionhuippua, vaan tyyppi on tasaisen suosittu 1900-luvun ajan. 2000-luvulla Anja-tyyppi on selvästi Aija-tyyppiä suositumpi. Etunimien suosionvaihtelututkimuksissa on tähän asti tukeuduttu prosenttilukuihin: mitä suuremman osuuden vuo-sittain syntyneistä lapsista kunkin nimen haltijat muodostavat, sitä suositumpi nimi on. Tutkielmassa kyseenalaiste-taan näin yksiselitteinen nimen suosion määritelmä. Vuosittain annettujen erilaisten nimien määrä on kasvanut merkittävästi 1900-luvun puolivälistä lähtien. Samalla valikoima, josta nimet valitaan, on kasvanut. Tämä suuri muutos nimenannossa pitäisi ottaa huomioon etunimien suosionvaihtelututkimuksissa. Vuoden yleisimmin valittu nimi 2000-luvulla ei voi saada yhtä suurta prosenttiosuutta kuin vuoden kärkinimi 1950-luvulla, mutta se ei välttä-mättä tee nimestä vähemmän suosittua.

A síndrome mielodisplásica primária (SMD) compreende um grupo de doenças hematopoéticas clonal de célula tronco pluripotente cacacterizada por vários graus de pancitopenia e alterações morfológica das células hematopoeticas e risco aumentado de transformação para leucemia mielóide aguda. A citogenética e a morfologia da medula óssea desempenham um papel fundamental para o diagnóstico e o prognóstico desses pacientes. Alterações cromossômicas são encontradas em aproximadamente 30-50% dos casos. Devido à importância da análise desses fatores para escolha terapêutica, torna-se necessário definir as alterações morfológicas e citogenéticas que possam contribuir para o prognóstico. Esse trabalho visa correlacionar as características morfológicas e citogenéticas da medula óssea em pacientes com SMD primária com as classificações OMS e FAB e com o IPSS. Foram estudados 32 pacientes com SMD primária diagnosticados entre 2000 e 2009 no HUPE-UERJ. As características clínicas foram analisadas através do levantamento de prontuários. A análise citogenética foi feita pela técnica de bandeamento GTG em células da medula ossea. A análise morfológica da biópsia de medula óssea e do mielograma foram realizadas através da revisão de lâminas. Vinte e três pacientes foram classificados em estágios iniciais da doença (22 AR, 1 ARSA) e 9 em estágio avançado AREB de acordo com a FAB. Alterações cromossômicas foram detectadas em 16 pacientes (50%). As mais frequentes foram: del(11)(q23) e del(17p). Dos pacientes com doença avançada, seis (66%) apresentaram aumento significativo da relação M:E (p=0,003) e sete (77%) possuíam alterações arquiteturais acentuadas (p<0,001) em comparação ao grupo de doença inicial. Pacientes classificados como intermediário 2 e alto risco pelo IPSS tiveram importante perda arquitetural (p<0,001), número significativamente maior de micromegacariócitos (p=0,017) e seis (85%) sofreram transformação leucêmica (p=0,006). ALIP foi significantemente aumentada nos pacientes de pior prognóstico (p=0,0 1) e naqueles com doença avançada (p=0,001). Nossos resultados apresentaram implicações potenciais para o diagnóstico e o prognóstico da SMD primária. As alterações morfológicas foram associadas com as classificações FAB, OMS e com os grupos de risco segundo o IPSS.

The economic and social consequences of international trade agreements have become a major area of inquiry in development studies in recent years. As evidenced by the energetic protests surrounding the Seattle meeting of the World Trade Organization (WTO) in December 1999 and the controversy about China's admission to the WTO, such agreements have also become a focus of political conflict in both the developed and developing countries. At issue are questions of job gains and job losses in different regions, prices paid by consumers, acceptable standards for wages and working conditions in transnational manufacturing industries, and the quality of the environment. All these concerns have arisen with regard to the North American Free Trade Agreement (NAFTA) and can be addressed through an examination of changes in the dynamics of the apparel industry in the post-NAFTA period.1 In this book, we examine the evolution of the apparel industry in North America in order to address some of these questions as they pertain to North America, with an eye toward the broader implications of our findings. We also consider the countries of the Caribbean Basin and Central America, whose textile and apparel goods are now allowed to enter the U.S. market on the same basis as those from Canada and Mexico (Odessey 2000). © 2009 by Temple University Press.

El presente trabajo plantea la utilización del Índice de Vegetación Normalizado (IVN) para identificar diferentes zonas de riesgo a fasciolosis ovina y bovina. Para tal fin se empleó el producto de IVN compuesto cada 16 días de 250 metros de resolución de la serie MODIS, con el que se generó el IVN promedio para el período 2000 - 2009. El área de estudio situada en el oeste de la provincia de Río Negro, tiene una superficie total de 2.700.000 hectáreas. A partir de los resultados de los análisis coprológicos, realizados durante el mismo período, en el Laboratorio de Parasitología de la EEA INTA Bariloche se calculó, para 25 establecimientos del área de estudio la prevalencia de fasciolosis (P FH). El rango de afectación observado varió según los establecimientos del 0 al 100 por ciento. Dado que los mallines proporcionan el ambiente donde se desarrolla el huésped intermediario de Fasciola hepatica, se identificó y se extrajo para cada establecimiento el valor de IVN promedio correspondiente a estos sitios. Según estos valores, se reclasificaron las áreas de mallines en tres clases. La correlación entre la prevalencia y el área ocupada por cada clase de IVN resultaron estadísticamente significativas (p menor a 0,05) y mostraron una fuerte relación entre dos clases de IVN y la prevalencia de fasciolosis. En base a los resultados obtenidos se generó un mapa de riesgo a fasciolosis para toda el área de estudio. Este trabajo sugiere que la proporción ocupada por las diferentes clases de IVN puede ser utilizada para predecir el nivel de riesgo de ocurrencia de la fasciolosis en el ganado ovino y bovino de la zona.

The aim of this paper is to investigate the role of phytoplankton nutritional status in the formation of the spring bloom regularly observed at the station L4 in the Western English Channel. Using a modelling approach, we tested the hypothesis that the increase in light from winter to spring induces a decrease in diatom nutritional status (i.e., an increase in the C:N and C:P ratios), thereby reducing their palatability and allowing them to bloom. To this end, a formulation describing the Stoichiometric Modulation of Predation (SMP) has been implemented in a simplified version of the European Regional Seas Ecosystem Model (ERSEM). The model was coupled with the General Ocean Turbulence Model (GOTM), implemented at the station L4 and run for 10 years (2000-.2009). Simulated carbon to nutrient ratios in diatoms were analysed in relation to microzooplankton biomass, grazing and assimilation efficiency. The model reproduced in situ data evolutions and showed the importance of microzooplankton grazing in controlling the early onset of the bloom. Simulation results supported our hypothesis and provided a conceptual model explaining the formation of the diatom spring bloom in the investigated area. However, additional data describing the microzooplankton grazing impact and the variation of carbon to nutrient ratios inside phytoplanktonic cells are required to further validate the proposed mechanisms.

The development of cultural policy analysis by social science has been produced a theorization about cultural policy models from sociology and political science. This analysis shows the influence of the national model of cultural policy on the forms of governance and management of cultural facilities. However, in this paper we will defend that currently the local model of cultural policy decisively influences the model of cultural institutions. This is explained by the growing importance of culture in local development strategies. In order to demonstrate this we will analyze the case of the Barcelona Model of local development and cultural policy, that is characterized for the level of local government leadership, multilevel governance, the use of culture in urban planning processes and a tendency to use public-private partnership in public management. This Model influences the genesis and development of the cultural facilities and it produces a singular and relatively successful model.

This article assesses the condition of the Cultural Heritage as a form of capital that gives rise to a significant flow of economic returns widely outweighing the effort it takes to preserve it. More specifically, the data related to Spain is provided from the perspective of aggregate demand drawing up an estimation of both the direct and indirect economic impacts arising from the Cultural Heritage valuation. The results highlight again the relevance of cultural tourism in the delivery of these economic returns and as a catalyst of activities leading to the sustainable socioeconomic devel-opment of multiple territories.

Sydney playwright Lachlan Philpott’s Bison (2000/2009) is immersed in a sweaty, summery Antipodean scene of bronzed and toned bodies. It is located in the flora and fauna of gum trees and biting ants. Yet, despite this, it could be argued that at its heart it is not a specifically Australian site, but an all-too translatable scene that seems to be played out in gay clubs, bars, chatrooms and saunas around the Western world: men repeating patterns, looking for sex or love; checking out bodies, craving perfection; avoiding, and occasionally seeking, disease. At least, that was my assumption when I decided to direct the play in Belfast, Northern Ireland, in 2009. Philpott came to Belfast to workshop the play with the actors and, as a group, we restructured the play and tried to find a way to ‘de-Australianise’ it without necessarily placing it in a new geographical place - Northern Ireland - through linguistic clues in the text. As Philpott put it: ‘Let’s not make this play about Belfast or Sydney or London or anywhere because it is not a fair reflection of these scenes. Maybe we should just identify the generic elements of this world and then make Bison a play that reflects gaytown – because the rituals are all the same in Western society’. The experience of doing the play in Belfast made clear, however, that ideas of a global gay identity/experience –though highly marketed – fail to account for the vastly different situations of embodied gay experience. And the Northern Irish gay experience, while it has imported the usual ‘generic’ tropes of gayness, sits within a specific cultural context in which the farsighted legislation on equality for gays (imposed by either London or the EU) vastly outstrips wider societal thinking. For many in Northern Ireland, erstwhile MP Iris Robinson’s comments about homosexuality being an ‘abomination’ were a reason to support her, rather than to reject her. For me, the comments were the catalyst to doing Bison in Belfast.

This paper is concerned with the language of policy documents in the field of health care, and how ‘readings’ of such documents might be validated in the context of a narrative analysis. The substantive focus is on a comparative study of UK health policy documents (N=20) as produced by the various assemblies, governments and executives of England, Scotland, Wales and Northern Ireland during the period 2000-2009. Following an identification of some key characteristics of narrative structure the authors indicate how text-mining strategies allied with features of semantic and network analysis can be used to unravel the basic elements of policy stories and to facilitate the presentation of data in such a way that readers can verify the strengths (and weaknesses) of any given analysis – with regard to claims concerning, say, the presence, absence, or relative importance of key ideas and concepts. Readers can also ‘see’ how the different components of any one story might fit together, and to get a sense of what has been excluded from the narrative as well as what has been included, and thereby assess the reliability and validity of interpretations that have been placed upon the data.
