Death, Ancestors, and HIV/AIDS among the Akan of Ghana

This is a study of crises caused by HIV/AIDS among the Akan of Ghana. It creates more awareness about the epidemic and has indicated other possible paths for campaign strategies. The pandemic has many devastating consequences; yet new infections are recorded daily despite campaigns against the disease. The search for therapy often sees the use of multiple outlets, which expresses Ghana's pluralistic medical system based on Kleinman's sector analytical model involving Western medicine, self-therapy, and folk healing. But it also leaves individuals and kin members in financial quandary. The fieldwork for this study is mainly through participant observation lasting 13 months (February 2003 to March 2004) among the Akan; in addition, some archival materials have been used. The Akan people live in the coastal south and forest zone of Ghana. Every Akan village or town is made up of corporate lineages, and social organisation is based on matrilineal descent. The society is holistic because the matrilineages seek the welfare of all their members. Meyer Fortes, R. S. Rattray and others on the Akan noticed this encompassing nature in the lineage organisation; but they did not make it salient (or failed to notice it) during illness, efforts for healing, and the care of the sick member. HIV/AIDS is an illness which shows the encompassing nature of the Akan matrilineage. It also reveals many contradictions in the group, viz. stigmatisation, abandonment, and attitudes that do not express altruism in a group expected to be closely-knit based on members' belief that they are of the 'same blood'. The crises have been analyzed in the total social system because the disease creates breaches at various levels of social interaction. An analysis of crises in a group is not far-fetched; Victor Turner has shown the way among the Ndembu and has revealed the contraditions in the seemingly uneventful life in the group. This study has identified that in dealing with HIV/AIDS patients and crises about the disease we are dealing with 'holistic' patients. Their cases produce many changes in the matrilineal structure--many orphans are being created and the care of patients is increasingly falling on the elderly. HIV/AIDS also challenges Akan cosmology because, for example, an AIDS death in local notions is a 'bad' demise which fails to produce ancestors who reproduce the society through reincarnation. Campaigns could emphasize this notion. The study begins with a description of the holistic nature of Akan matriliny, and the patients have been described as 'holistic' because their crises affect other people in the holistic society. Chapter 2 discusses the importance of ancestors as the starting points for social order who are constantly revered (in rites invoving the chief, Chapter 4). Chapter 3 focuses on funerals as an important social performance for the welfare of the dead and the living. Chapter 5 concentrates on HIV/AIDS as an illness threat marked by dominant discourses such as poverty, sexuality, migration, and condom use. Chapter 6 analyzes the attempts for therapy, and traditional healers' claims to have a cure. The efforts for therapy continues with spiritual church healing in Chapter 7, and chapter 8 is devoted to care of the patients and its inherent crises. Chapter 9 analyzes the effects of HIV/AIDS afflictions and AIDS deaths on the matrilineal group and in society. The study ends with a short part, devoted to Recommendations based on the findings in this investigation.

Collective Network Capability in International Project Business Networks - A Case Study of the Business Network for the Ashanti Electrification Project in Ghana

Despite thirty years of research in interorganizational networks and project business within the industrial networks approach and relationship marketing, collective capability of networks of business and other interorganizational actors has not been explicitly conceptualized and studied within the above-named approaches. This is despite the fact that the two approaches maintain that networking is one of the core strategies for the long-term survival of market actors. Recently, many scholars within the above-named approaches have emphasized that the survival of market actors is based on the strength of their networks and that inter-firm competition is being replaced by inter-network competition. Furthermore, project business is characterized by the building of goal-oriented, temporary networks whose aims, structures, and procedures are clarified and that are governed by processes of interaction as well as recurrent contracts. This study develops frameworks for studying and analysing collective network capability, i.e. collective capability created for the network of firms. The concept is first justified and positioned within the industrial networks, project business, and relationship marketing schools. An eclectic source of conceptual input is based on four major approaches to interorganizational business relationships. The study uses qualitative research and analysis, and the case report analyses the empirical phenomenon using a large number of qualitative techniques: tables, diagrams, network models, matrices etc. The study shows the high level of uniqueness and complexity of international project business. While perceived psychic distance between the parties may be small due to previous project experiences and the benefit of existing relationships, a varied number of critical events develop due to the economic and local context of the recipient country as well as the coordination demands of the large number of involved actors. The study shows that the successful creation of collective network capability led to the success of the network for the studied project. The processes and structures for creating collective network capability are encapsulated in a model of governance factors for interorganizational networks. The theoretical and management implications are summarized in seven propositions. The core implication is that project business success in unique and complex environments is achieved by accessing the capabilities of a network of actors, and project management in such environments should be built on both contractual and cooperative procedures with local recipient country parties.

"Haluan tuonne heti!" : Tulevaisuuskuvia ghanalaisten, isobritannialaisten,suomalaisten ja tansanialaisten lasten piirustuksissa

"I want there now!" Images of the future in the drawings of Ghanaian, British, Finnish and Tanzanian children The aim of the Thesis is to examine what kind of images children aged between 8 and 12 years in Ghana, Great Britain, Finland and Tanzania hold of their future. The study is a qualitative analysis based on data that consists of 214 drawings, digitally photographed and analysed using AtlasTI computer program. The data was coded and divided into " families " whose frequencies were compared in order to maintain results. The assignment was given to the children in the language used in the school and it was similar in each country. The children were introduced to the idea with a set of stimulating questions and after that they were asked to draw and colour with a pen a picture of 1) him/herself as an adult, 2) his/her future home and 3) the people and the animals they think they will be living with. The children were also asked to write down the country and the place they believe to live in their future. They were also encouraged to write down e.g. their dream profession, what they would like to have as hobbies in their adulthood and other important things in their lives. The analysis focuses on the content of the drawings instead of artistic or psychological interpretations. The differences between the drawings from different countries as well as the differences in a single country were significant. The current trends and the experiences children had lived through were present in the drawings. There were no differences in the colour of the skin and the most popular professions were doctor, police and football player. The football was very strongly present in all of the data; almost fourth of the children had either drawn or mentioned football as their future profession or hobby. Different flora was present in 84% of Tanzanian and 70% of Ghanaian drawings compared to the 23% of British and 17% of Finnish drawings. Of all the family forms a dream of the traditional nuclear family could be found among 29% of the drawings. Compared to that a total of 30% wanted either a child of their own without a spouse (15%) or a spouse without a child (15%). Also grandparents, childhood friends, other adults, animals or even space aliens were present and sharing a home with the children in the drawings. Of all children 15% wanted to live totally alone in the future. This was most typical (38%) among the Finnish boys. The cat and the dog were the most popular animals to appear in the drawings. Moving abroad proved to be purely a western phenomenon, dreamed by 57% of the British and 18% of the Finnish children. As results, a negative self-image, violence, lack of expressions of positive feelings and solitude among the Finnish boys in the data were very concerning.

Human parvovirus B19: tissue persistence and prevalence of prototypic and new variants

Human parvovirus B19 is a minute ssDNA virus causing a wide variety of diseases, including erythema infectiosum, arthropathy, anemias, and fetal death. After primary infection, genomic DNA of B19 has been shown to persist in solid tissues of not only symptomatic but also of constitutionally healthy, immunocompetent individuals. In this thesis, the viral DNA was shown to persist as an apparently intact molecule of full length, and without persistence-specific mutations. Thus, although the mere presence of B19 DNA in tissue can not be used as a diagnostic criterion, a possible role in the pathogenesis of diseases e.g. through mRNA or protein production can not be excluded. The molecular mechanism, the host-cell type and the possible clinical significance of B19 DNA tissue persistence are yet to be elucidated. In the beginning of this work, the B19 genomic sequence was considered highly conserved. However, new variants were found: V9 was detected in 1998 in France, in serum of a child with aplastic crisis. This variant differed from the prototypic B19 sequences by ~10 %. In 2002 we found, persisting in skin of constitutionally healthy humans, DNA of another novel B19 variant, LaLi. Genetically this variant differed from both the prototypic sequences and the variant V9 also by ~10%. Simultaneously, B19 isolates with DNA sequences similar to LaLi were introduced by two other groups, in the USA and France. Based on phylogeny, a classification scheme based on three genotypes (B19 types 1-3) was proposed. Although the B19 virus is mainly transmitted via the respiratory route, blood and plasma-derived products contaminated with high levels of B19 DNA have also been shown to be infectious. The European Pharmacopoeia stipulates that, in Europe, from the beginning of 2004, plasma pools for manufacture must contain less than 104 IU/ml of B19 DNA. Quantitative PCR screening is therefore a prerequisite for restriction of the B19 DNA load and obtaining of safe plasma products. Due to the DNA sequence variation among the three B19 genotypes, however, B19 PCR methods might fail to detect the new variants. We therefore examined the suitability of the two commercially available quantitative B19 PCR tests, LightCycler-Parvovirus B19 quantification kit (Roche Diagnostics) and RealArt Parvo B19 LC PCR (Artus), for detection, quantification and differentiation of the three B19 types known, including B19 types 2 and 3. The former method was highly sensitive for detection of the B19 prototype but was not suitable for detection of types 2 and 3. The latter method detected and differentiated all three B19 virus types. However, one of the two type-3 strains was detected at a lower sensitivity. Then, we assessed the prevalence of the three B19 virus types among Finnish blood donors, by screening pooled plasma samples derived from >140 000 blood-donor units: none of the pools contained detectable levels of B19 virus types 2 or 3. According to the results of other groups, B19 type 2 was absent also among Danish blood-donors, and extremely rare among symptomatic European patients. B19 type 3 has been encountered endemically in Ghana and (apparently) in Brazil, and sporadical cases have been detected in France and the UK. We next examined the biological characteristics of these virus types. The p6 promoter regions of virus types 1-3 were cloned in front of a reporter gene, the constructs were transfected into different cell lines, and the promoter activities were measured. As a result, we found that the activities of the three p6 promoters, although differing in sequence by >20%, were of equal strength, and most active in B19-permissive cells. Furthermore, the infectivity of the three B19 types was examined in two B19-permissive cell lines. RT-PCR revealed synthesis of spliced B19 mRNAs, and immunofluorescence verified the production of NS1 and VP proteins in the infected cells. These experiments suggested similar host-cell tropism and showed that the three virus types are strains of the same species, i.e. human parvovirus B19. Last but not least, the sera from subjects infected in the past either with B19 type 1 or type 2 (as evidenced by tissue persistence of the respective DNAs), revealed in VP1/2- and VP2-EIAs a 100 % cross-reactivity between virus types 1 and 2. These results, together with similar studies by others, indicate that the three B19 genotypes constitute a single serotype.

Forest governance and climate change adaptation : Case studies of four African countries

Africa is threatened by climate change. The adaptive capacity of local communities continues to be weakened by ineffective and inefficient livelihood strategies and inappropriate development interventions. One of the greatest challenges for climate change adaptation in Africa is related to the governance of natural resources used by vulnerable poor groups as assets for adaptation. Practical and good governance activities for adaptation in Africa is urgently and much needed to support adaptation actions, interventions and planning. The adaptation role of forests has not been as prominent in the international discourse and actions as their mitigation role. This study therefore focused on the forest as one of the natural resources used for adaptation. The general objective of this research was to assess the extent to which cases of current forest governance practices in four African countries Burkina Faso, The Democratic Republic of Congo (DRC), Ghana and Sudan are supportive to the adaptation of vulnerable societies and ecosystems to impacts of climate change. Qualitative and quantitative analyses from surveys, expert consultations and group discussions were used in analysing the case studies. The entire research was guided by three conceptual sets of thinking forest governance, climate change vulnerability and ecosystem services. Data for the research were collected from selected ongoing forestry activities and programmes. The study mainly dealt with forest management policies and practices that can improve the adaptation of forest ecosystems (Study I) and the adaptive capacity through the management of forest resources by vulnerable farmers (Studies II, III, IV and V). It was found that adaptation is not part of current forest policies, but, instead, policies contain elements of risk management practices, which are also relevant to the adaptation of forest ecosystems. These practices include, among others, the management of forest fires, forest genetic resources, non-timber resources and silvicultural practices. Better livelihood opportunities emerged as the priority for the farmers. These vulnerable farmers had different forms of forest management. They have a wide range of experience and practical knowledge relevant to ensure and achieve livelihood improvement alongside sustainable management and good governance of natural resources. The contributions of traded non-timber forest products to climate change adaptation appear limited for local communities, based on their distribution among the stakeholders in the market chain. Plantation (agro)forestry, if well implemented and managed by communities, has a high potential in reducing socio-ecological vulnerability by increasing the food production and restocking degraded forest lands. Integration of legal arrangements with continuous monitoring, evaluation and improvement may drive this activity to support short, medium and long term expectations related to adaptation processes. The study concludes that effective forest governance initiatives led by vulnerable poor groups represent one practical way to improve the adaptive capacities of socio-ecological systems against the impacts of climate change in Africa.

Physical Properties of Deep Drill Cores : Implications for Meteorite Impact Effects and Crustal Structures

Physical properties provide valuable information about the nature and behavior of rocks and minerals. The changes in rock physical properties generate petrophysical contrasts between various lithologies, for example, between shocked and unshocked rocks in meteorite impact structures or between various lithologies in the crust. These contrasts may cause distinct geophysical anomalies, which are often diagnostic to their primary cause (impact, tectonism, etc). This information is vital to understand the fundamental Earth processes, such as impact cratering and associated crustal deformations. However, most of the present day knowledge of changes in rock physical properties is limited due to a lack of petrophysical data of subsurface samples, especially for meteorite impact structures, since they are often buried under post-impact lithologies or eroded. In order to explore the uppermost crust, deep drillings are required. This dissertation is based on the deep drill core data from three impact structures: (i) the Bosumtwi impact structure (diameter 10.5 km, 1.07 Ma age; Ghana), (ii) the Chesapeake Bay impact structure (85 km, 35 Ma; Virginia, U.S.A.), and (iii) the Chicxulub impact structure (180 km, 65 Ma; Mexico). These drill cores have yielded all basic lithologies associated with impact craters such as post-impact lithologies, impact rocks including suevites and breccias, as well as fractured and unfractured target rocks. The fourth study case of this dissertation deals with the data of the Paleoproterozoic Outokumpu area (Finland), as a non-impact crustal case, where a deep drilling through an economically important ophiolite complex was carried out. The focus in all four cases was to combine results of basic petrophysical studies of relevant rocks of these crustal structures in order to identify and characterize various lithologies by their physical properties and, in this way, to provide new input data for geophysical modellings. Furthermore, the rock magnetic and paleomagnetic properties of three impact structures, combined with basic petrophysics, were used to acquire insight into the impact generated changes in rocks and their magnetic minerals, in order to better understand the influence of impact. The obtained petrophysical data outline the various lithologies and divide rocks into four domains. Based on target lithology the physical properties of the unshocked target rocks are controlled by mineral composition or fabric, particularly porosity in sedimentary rocks, while sediments result from diverse sedimentation and diagenesis processes. The impact rocks, such as breccias and suevites, strongly reflect the impact formation mechanism and are distinguishable from the other lithologies by their density, porosity and magnetic properties. The numerous shock features resulting from melting, brecciation and fracturing of the target rocks, can be seen in the changes of physical properties. These features include an increase in porosity and subsequent decrease in density in impact derived units, either an increase or a decrease in magnetic properties (depending on a specific case), as well as large heterogeneity in physical properties. In few cases a slight gradual downward decrease in porosity, as a shock-induced fracturing, was observed. Coupled with rock magnetic studies, the impact generated changes in magnetic fraction the shock-induced magnetic grain size reduction, hydrothermal- or melting-related magnetic mineral alteration, shock demagnetization and shock- or temperature-related remagnetization can be seen. The Outokumpu drill core shows varying velocities throughout the drill core depending on the microcracking and sample conditions. This is similar to observations by Kern et al., (2009), who also reported the velocity dependence on anisotropy. The physical properties are also used to explain the distinct crustal reflectors as observed in seismic reflection studies in the Outokumpu area. According to the seismic velocity data, the interfaces between the diopside-tremolite skarn layer and either serpentinite, mica schist or black schist are causing the strong seismic reflectivities.

"But we are dong it!" Ghanalaisen Hon kunnan naisvaltuutettujen työssään kohtaamat haasteet

Tässä tutkielmassa kuvataan tekijöitä, jotka haittaavat naisten toimintaa kunnanvaltuutettuina tehokkaalla tai naisten itsensä haluamalla tavalla sekä vaikuttavat heidän mahdollisuuksiinsa vaikuttaa päätöksentekoon Ghanan paikallishallinnossa. Tutkimuksessa analysoidaan sekä paikallishallintoon nimitettyjen että vaaleilla valittujen naisten asemaa valtuutettuina, mitä aiemmissa tutkimuksissa Ghanan paikallishallinnosta ei ole tehty. Ghanassa nimittäin 30 prosenttia kunnanvaltuutetuista nimitetään tehtäväänsä. Lopulta tutkimuksessa analysoidaan nimitettyjen ja vaaleilla valittujen naisvaltuutettujen mahdollisuuksia edustaa halutessaan naisten intressejä. Hon kunnanvaltuuston tapaus oli erittäin kiinnostava, sillä vuonna 2006 naisten osuus kunnanvaltuutetuista nousi 35,7 prosenttiin. Aiemmin naisia oli ollut valtuustossa huomattavasti vähemmän. Tutkimusta varten tehtiin kenttätyötä Ghanassa. Tutkimus perustuu 16 Hon kunnanvaltuutetun haastatteluun ja kunnan pormestarin kanssa käytyyn keskusteluun. Kartoitan Hon kunnanvaltuuston naisvaltuutettujen toimintaan vaikuttavia tekijöitä ja naisedustajien työssä kohtaamia esteitä sekä naisvaltuutettujen omien kokemusten että miespuolisten kunnanvaltuutettujen näkemysten kautta. Tutkimustulokset osoittivat, että naisvaltuutetut kohtasivat työssään monia haasteita. Moni esteistä oli yhdistettävissä toimimattomiin rakenteisiin, miehisiin normeihin ja käytäntöihin sekä toisaalta naisten miehiä huonompaan sosiaaliseen asemaan. Esimerkiksi liikkuminen vaalialueella ja jopa kokouksiin saapuminen olijoillekin naisille suuri haaste. Myös paikallisten ihmisten vaatimukset saada henkilökohtaista rahallista hyötyä valtuutetuilta nousivat esiin naisten esteenä. Toisaalta näkemysten esittäminen kokouksissa vaikutti naisille ongelmalliselta eli huomio kiinnittyi naisten poliittiseen kokemattomuuteen sekä valtuuston institutionaaliseen kulttuuriin. Nimitettyjen naisten asema kunnanvaltuustossa paljastui erilaiseksi kuin vaaleilla valittujen naisedustajien. Nimitettyjen edustajien järjestelmä, jota on perusteltu mahdollisuutena lisätä naisten intressien edustusta paikallishallinnossa, näyttäytyi tutkimusten tulosten perusteella kyseenalaisena keinona lisätä naisten edustusta paikallishallinnossa. Nimitettyjä valtuutettuja ei esimerkiksi nähty legitiimeinä ihmisten edustajina paikallishallinnossa vaan heidän katsottiin edistävän puolueensa intressejä, ei paikallisten ihmisten. Nimitettyjen edustajien järjestelmä myös paljastui paikalliselle poliittiselle eliitille suosiolliseksi järjestelmäksi valita kiintiön kautta edustajiksi itselleen, ei paikallisille ihmisille tai paikallisille naisille, sopivia edustajia.
