Main themes and missing elements in psychological research into child maltreatment in Africa

These 18 papers on aspects of violence against children add to a growing body of African literature that tends to focus on four major themes. The first three are generic to research worldwide, and include efforts to uncover the extent of adverse experiences during childhood, describe the effects on health and well-being, and examine professional practices, concepts and myths. The fourth theme is more particular to Africa, and is focused on understanding how to protect children within the context of poverty, some harmful traditional practices and community violence. Despite best efforts by researchers and child rights advocates, there are missing elements in the research to date, including scant focus on the problems of emotional abuse and neglect, and limited attention to evaluation of the effectiveness of prevention and care programs.

The Phraseology and Structure of Latin Building Inscriptions in Roman North Africa

This study analyses the diction of Latin building inscriptions. Despite its importance, this topic has rarely been discussed before: the most substantial contribution on the subject is a short dissertation by Klaus Gast (1965) that focuses on 100 inscriptions dating mostly from the Republican period. Marietta Horster (2001) also touched upon this theme in her thesis on imperial building inscriptions. I have collected my source material in North Africa because more Latin building inscriptions dating from the Imperial period have survived there than in any other area of the Roman Empire. By means of a thorough and independent survey, I have assembled all relevant African Latin building inscriptions datable to the Roman period (between 146 BC and AD 425), 1002 texts, into a corpus. These inscriptions are all fully edited in Appendix 1; Appendix 2 contains references to earlier editions. To facilitate search operations, both are also available in electronic form. They are downloadable from the address http://www.helsinki.fi/hum/kla/htm/jatkoopinnot.htm. Chapter one is an introduction dealing with the nature of building inscriptions as source material. Chapter two offers a statistical overview of the material. The following main section of the work falls into five chapters, each of which analyses one main part of a building inscription. An average building inscription can be divided into five parts: the starting phrase opens the inscription (a dedication to gods, for example), the subject part identifies the builder, the object part describes the constructed or repaired building, the predicate part records the building activity and the supplement part offers additional information on the project (it can specify the funding, for instance). These chapters are systematic and chronological and their purpose is to register and interpret the phrases used, to analyse reasons for their use and for their popularity among the different groups of builders. Chapter eight, which follows the main section of the work, creates a typology of building inscriptions based on their structure. It also presents the most frequently attested types of building inscriptions. The conclusion describes, on a general level, how the diction of building inscriptions developed during the period of study and how this striking development resulted from socio-economic changes that took place in Romano-African society during Antiquity. This study shows that the phraseology of building inscriptions had a clear correlation both with the type of builder and with the date of carving. Private builders tended to accentuate their participation (especially its financial side) in the project; honouring the emperor received more emphasis in the building inscriptions set up by communities; the texts produced by the army were concise. The chronological development is so clear that it enables stylistic dating. At the beginning of the imperial period the phrases were clear, concrete, formal and stereotyped but by Late Antiquity they have become vague, subjective, flexible, varied and even rhetorically or poetically coloured.

Erityisopetus muutoksen kynnyksellä - tilastollinen kuvaus erityisopetusjärjestelmästä ja sen määrällisestä kehityksestä 1970-luvun lopulta vuoteen 2008

The number of Finnish pupils attending special education has increased for more than a decade (Tilastokeskus 1999, 2000, 2001, 2003, 2004, 2005a, 2006b, 2007b, 2008b, 2008e, 2009b; Virtanen ja Ratilainen 1996). In the year 2007 nearly third of Finnish comprehensive school pupils took part in special needs education. According to the latest statistics, in the autumn of 2008 approximately 47 000 pupils have been admitted or transferred to special education and approximately 126 000 pupils received part-time special education during the 2007 - 2008 academic year. (Tilastokeskus 2008b, 2009b.) The Finnish special education system is currently under review. The Reform, both in legislation and in practice, began nationwide in the year 2008 (e.g. Special education strategy document, November 2007 and the development project Kelpo). The aim of the study was the statistical description of the Finnish special education system and on the other hand to gain a deeper understanding about the Finnish special education system and its quantitative increase, by analysis based on the nationwide statistical information. Earlier studies have shown that the growth in special education is affected by multiple independent variables and cannot be solely explained by the pupil characteristics. The statistical overview and analysis have been carried out in two parts. In the first part, the description and analysis were based on statistical time series from the academic year 1979 -1980 until 2008. While, in the second, more detailed description and analysis, based on comparable time series from 1995 to 2008 and from 2001-2002 to 2007-2008, is presented. Historical perspective was one part of this study. There was an attempt to find reasons explaining the observed growth in the special needs education from late 1960s to 2008. The majority of the research was based on the nationwide statistics information. In addition to this, materials including educational legislation literature, different kind of records of special education and preceding studies were also used to support the research. The main results of the study, are two statistical descriptions and time series analysis of the quantitative increase of the special needs education. Further, a summary of the plausible factors behind the special education system change and its quantitative increase, is presented. The conclusions coming from the study can be summarised as follows: the comparable statistical time series analysis suggests that the growth in special education after the year 1999 could be a consequence of the changes in the structure of special education and that new group of pupils have been directed to special needs education.

Livelihood, land use and environment interactions in the highlands of East Africa

This study aims at improving understanding of the interactions of livelihoods and the environment focusing on both socio-economic and biodiversity implications of land use change in the context of population pressure, global and local markets, climate change, cultural and regional historical factors in the highlands of East Africa. The study is based on three components (1) two extensive livelihood surveys, one on Mt. Kilimanjaro in Tanzania and the other in the Taita Hills of Kenya, (2) a land use change study of the southern slopes of Mt. Kilimanjaro focusing on land use trends between 1960s and 1980s and 1980s and 2000 and (3) a bird diversity study focusing on the potential impacts of the future land use change on birds in the main land use types on the slopes and the adjacent plains of Mt. Kilimanjaro. In addition, information on the highlands in Embu and the adjacent lowlands in Mbeere of Kenya are added to the discussion. Some general patterns of livelihood, land use and environment interactions can be found in the three sites. However, the linkages are very complex. Various external factors at different times in history have influenced most of the major turning points. Farmers continually make small adaptations to their farming practices, but the locally conceived alternatives are too few. Farmers lack specific information and knowledge on the most suitable crops, market opportunities and the quality requirements for growing the crops for markets. Population growth emerges as the most forceful driver of land use and environmental change. The higher altitudes have become extremely crowded with population densities in some areas higher than typical urban population densities. Natural vegetation has almost totally been replaced by farmland. Decreasing farm size due to population pressure is currently threatening the viability of whole farming systems. In addition, capital-poor intensification has lead to soil fertility depletion. Agricultural expansion to the agriculturally marginal lowlands has created a new and distinct group of farmers struggling constantly with climate variability causing frequent crop failures. Extensification to the fragile drylands is the major cause of fragmentation and loss of wildlife habitat. The linkages between livelihoods, land use and the environment generally point to degradation of the environment leading to reduced environmental services and ecosystem functions. There is no indication that the system is self-regulating in this respect. Positive interventions will be needed to maintain ecosystem integrity.

Paleomagnetic and rock magnetic study with emphasis on the Precambrian intrusions and impact structures in Fennoscandia and South Africa

The importance of supercontinents in our understanding of the geological evolution of the planet Earth has been recently emphasized. The role of paleomagnetism in reconstructing lithospheric blocks in their ancient paleopositions is vital. Paleomagnetism is the only quantitative tool for providing ancient latitudes and azimuthal orientations of continents. It also yields information of content of the geomagnetic field in the past. In order to obtain a continuous record on the positions of continents, dated intrusive rocks are required in temporal progression. This is not always possible due to pulse-like occurrences of dykes. In this work we demonstrate that studies of meteorite impact-related rocks may fill some gaps in the paleomagnetic record. This dissertation is based on paleomagnetic and rock magnetic data obtained from samples of the Jänisjärvi impact structure (Russian Karelia, most recent 40Ar-39Ar age of 682 Ma), the Salla diabase dyke (North Finland, U-Pb 1122 Ma), the Valaam monzodioritic sill (Russian Karelia, U-Pb 1458 Ma), and the Vredefort impact structure (South Africa, 2023 Ma). The paleomagnetic study of Jänisjärvi samples was made in order to obtain a pole for Baltica, which lacks paleomagnetic data from 750 to ca. 600 Ma. The position of Baltica at ca. 700 Ma is relevant in order to verify whether the supercontinent Rodinia was already fragmented. The paleomagnetic study of the Salla dyke was conducted to examine the position of Baltica at the onset of supercontinent Rodinia's formation. The virtual geomagnetic pole (VGP) from Salla dyke provides hints that the Mesoproterozoic Baltica - Laurentia unity in the Hudsonland (Columbia, Nuna) supercontinent assembly may have lasted until 1.12 Ga. Moreover, the new VGP of Salla dyke provides new constraint on the timing of the rotation of Baltica relative to Laurentia (e.g. Gower et al., 1990). A paleomagnetic study of the Valaam sill was carried out in order to shed light into the question of existence of Baltica-Laurentia unity in the supercontinent Hudsonland. Combined with results from dyke complex of the Lake Ladoga region (Schehrbakova et al., 2008) a new robust paleomagnetic pole for Baltica is obtained. This pole places Baltica on a latitude of 10°. This low latitude location is supported also by Mesoproterozoic 1.5 1.3 Ga red-bed sedimentation (for example the Satakunta sandstone). The Vredefort impactite samples provide a well dated (2.02 Ga) pole for the Kaapvaal Craton. Rock magnetic data reveal unusually high Koenigsberger ratios (Q values) in all studied lithologies of the Vredefort dome. The high Q values are now first time also seen in samples from the Johannesburg Dome (ca. 120 km away) where there is no impact evidence. Thus, a direct causative link of high Q values to the Vredefort impact event can be ruled out.

Regional Integration and the State : The Changing Nature of Sovereignty in Southern Africa and Europe

The study explores the role of the state in regional integration processes. The question is approached through theoretical discussion and two case-studies - SADC (Southern African Development Community) and the EU. The main research question of the study is, what are the possibilities and problems of the integration process in Southern Africa and how do they differ from the possibilities and problems of the integration process in Europe. The undelrying question of the study is why do states decide to participate in an integration process where they have to limit their sovereignty. Review of the theoretical discussion of the integration studies shows that the integration process is affected by several factors on different levels of the international system. But the state plays a central role in integration processes - integration processes are inititated and carried on by the participatig states. The European integration process shows that the interests of the state can change over time. At the beginning of the integration process, the objective was to strengthen participating states. Later EU member states have decided that it is in their interest to deepen the process even if it has meant limitation of their sovereignty. The determinant factor has been that the member states have considered it to be in their interst to deepen the process. In Southern Africa the integration process is only at the beginning. SADC aims to establish a free trade area by 2008. The biggest challenge is how to implement the integration process so that it benefits all member states in a region that is economically dominated by South Africa. In practice this can be achieved through establishment of corrective mechanisms, which ensure equitable distribution of benefits. This would require deeper integration and South Africa to adapt responsibility towards its regional partners. African integration processes in general have not been as successful as for example the EU. African states have been reluctant to limit their sovereignty in favour of regional organisations.This can be explained by the differences between European and African states. The EU member states have been democracies while African states have been characterised by concentration of power in the executive branch. Furthermore the political systems in Africa have been characterised by vertical clientelist reltionships. As a result it has not been in the interest of the political elite to limit the state sovereignty in favour of regional organisations. In recent years SADC has been relatively succesful in its integration process and reforms, but a lot remains to be done before the implementation of the free trade area can be succesful. The institutional structure and treaties of SADC differ from the structures of the EU. Member states are the main actors of the integration processes. Their differences are reflected in the process and produce different kinds of integration in different parts of the world.

The challenge of cancer control in Africa.

While the world is focused on controlling the spread of diseases such as HIV and malaria in the developing world, another approaching epidemic has been largely overlooked. The World Heath Organization predicts that there will be 16 million new cancer cases per year in 2020 and 70% of these will be in the developing world. Many of these cancers are preventable, or treatable when detected early enough. Establishing effective, affordable and workable cancer control plans in African countries is one step in the right direction toward limiting this epidemic.

Estudio epidemiologico de la prevalencia de cisticercosis bovina en el matadero Nuevo Carnic del municipio de Managua, Nicaragua en el periodo de Enero a Junio 2008

Con el objeto de conocer la prevalencia de Cisticercosis bovina, así como las regiones de mayor afectación y las implicaciones económicas que ello ocasiona en animales faenados en el matadero NUEVO CARNIC, ubicado en el km 10 carretera norte, un km. al norte para el periodo de enero a junio de l 2008, se llevó a cabo el presente estudio, l os datos recopilados se obtuvieron de los registros de matanza del primer semestre del año 2008 (enero a junio), los cuales provenían de los registros de inspección postmorten realizados por los inspectores veterinarios, quienes utilizan el método del reglamento de inspección veterinaria de la carne para la republica de Nicaragua. El presente estudio fue observacional de tipo transversal, por estar determinado en un momento de la actividad del matadero. La determinación de la prevalencia consistió en determinar el número de animales afectados, los cuales se relacionaron con el número de animales faenados por lotes y total. Al iniciarse el estudio, sólo se conocía el número total de individuos que se incluyeron. La medición de la cantidad de enfermedad y de los factores de exposición se realizó simultáneamente una vez seleccionada la muestra. Las variables evaluadas fueron, prevalencia por tamaño del lote y total de animales faenados, regiones anatómicas de mayor afectación y pérdidas económicas para los ganaderos por sanitización y condena. Se encontró una prevalencia de 0.85% con respecto al total de animales faenados, y un 0.04% para animales condenados. La categoría que presentó mayor prevalencia y pérdidas económicas por C. bovis fue toro, seguida de la categoría vacas. El municipio de mayor frecuencia de afectación fue Managua. Las procedencias de San Lorenzo, el Tuma, Ayapal, Paiwas, Muy Muy, Boaco, Nagarote, Estelí, y la Paz Centro fueron los municipios con mayor prevalencia con respecto al total de animales faenados. Cuando el tamaño del lote es mayor de 50 animales la probabilidad de ocurrencia de prevalencia por lote y total son mayores. La región anatómica con mayor prevalencia fueron los músculos maseteros, seguido de la lengua. Las pérdidas económicas para los productores ascendieron a más de 2,000 dólares por mes. Los meses de mayores pérdidas fueron Junio y Marzo. Las procedencias y los pesos no son factores a considerar en los porcentajes de afectación y prevalencia de la enfermedad.

Evaluación de emergía del medio ambiente y la economía de Nicaragua (1995-1999)

Este estudio muestra el análisis de emergía para Nicaragua para los años 1995-99. Los objetivos del presente trabajo son 1) conocer cuáles son las principales características del sistema económico y ambiental de Nicaragua haciendo uso de índices de emergía para describir la carga ambiental y la sostenibilidad del sistema, b) determinar cuál es la posición internacional de Nicaragua en términos de su sistema ecológico-económico y e) determinar cuál es la contribución del medio ambiente de Nicaragua a la economía del país, utilizando la metodología de análisis de emergía. Emergía (con m), es la cantidad de energía que es requerida para hacer algo, es la memoria de energía la cual fue degradada en su proceso de transformación. La metodología de análisis de emergía es útil en donde el crecimiento económico está generando controversia sobre el desarrollo de la economía y la protección del medio ambiente. En este trabajo se presenta un diagrama general de sistema para Nicaragua 1995-99 y una evaluación de emergía de la Base de recursos para Nicaragua. Los resultados indican que la fuente de emergía de la base de recursos para Nicaragua es la energía potencial química en la lluvia (275.97 E+20 sej/año) y se confirma que los recursos renovables más importantes son el ganadero (91.56 E+20 sej/año) y el agrícola (62.26 E+20 sej/año). La relación de emergía exportada a importada fue de 2.14/1, ubicando a Nicaragua como un país productor de recursos. Los diferentes índices calculados para Nicaragua (Relación Emergía/USD = 15.8 E+12 sej/año; Relación de Carga Ambiental =0.39; Relación de Inversión de Emergía= 0.21; Relación de Rendimiento Neto= 5.36 e Indice de Sostenibilidad = 13.86) demuestran que Nicaragua posee una economía subdesarrollada, con niveles tecnológicos pobres y baja intensidad de desarrollo económico. Los índices también indican una baja posición de Nicaragua en la jerarquía económica de naciones. La evaluación y análisis de emergía puede ser utilizado para determinar en términos cuantitativos como realizar de forma óptima y sostenible un buen manejo de los recursos naturales, la población y la economía de una región o país, en este caso de Nicaragua.

Estudio del proceso de floracion inducido por el acido giberelico (AG3) en nueve cultivares de quequisque (Xanthosoma spp) en Nicaragua

Se evaluó la floración inducida por tres aplicaciones (semanal y quincenal) de 0,500 y 1000 ppm de acido giberélico (AG3) en los cultivares de quequisque San Ramón, El Tuma, San Antonio, La Rampla, Malaquías,San Lucas, Casitas, Masaya y Apalí. Se utilizó el diseño de bloque completo al azar, con tres bloques, cuatro plantas/bloque y 12 plantas/cultivar. Se evaluó la altura de planta, grosor del pseudotallo, número de hojas y área foliar; momento de floración, número de flores, estructuras relacionadas a la floración, germinación del polen y receptividad del ovario. Previo a la aplicación los cultivares no diferían en desarrollo morfológico. El AG3 retrasó drásticamente el crecimiento de las plantas. Los cultivares iniciaron la floración 88-114 días después de la primera aplicación (ddpa). San Ramón, San Antonio y Malaquías iniciaron la floración 88 ddpa. La Rampla y San Lucas la iniciaron 114 ddpa. La floración duró dos meses. Las plantas produjeron 8 flores promedio. El cultivar San Antonio aplicado con 500 ppm de AG3 semanalmente produjo 102 flores. Aplicaciones quincenales de 1000 ppm indujeron 25 flores en San Ramón y El Tuma, 8 en San Lucas y Casitas. Además se produjeron: brácteas, brácteas múltiples, bráctea hoja de bandera y brácteas cubriendo hoja de bandera. La germinación del polen fue 90-100%. Altas temperaturas al inicio de la floracion afectaron la ántesis y la producción del polen. La receptividad del ovario fue 100%. Este es el primer estudio de inducción de floración en quequisque cuyos resultados son la base de futuros trabajos de mejora genética en el cultivo.

The valuation of riparian fisheries in Southern and Eastern Africa

This paper reviews the published and gray literature concerning economic valuations of river fisheries in eastern and southern Africa, extracting the best available information on their direct economic values and on the impacts of changes in water management on this value. It then assesses the methods used and makes recommendations regarding approaches to be used in future. The review concentrates on rivers with their associated floodplains and major deltas. The values and issues associated with estuaries and lakes are not considered.

Review of river fisheries valuation in West and Central Africa

This paper provides a review of the valuation of river fisheries in West and Central Africa. It is the general perception that, compared to the biological and ecological aspects of river fisheries, this particular subject area has received relatively little attention. Economic valuation is concerned with finding expression for what is important in life for human society. It should, therefore, be a central and integral part of government decision-making and policy. The review started with concepts and methods for valuation. Three main types of valuation techniques were identified: conventional economic valuations, economic impact assessments and socioeconomic investigations, and livelihood analysis. On the basis of a literature review, valuation information was then synthesized for the major regional river basins and large lakes, and also used to develop a series of national fisheries profiles. To supplement this broad perspective, a series of case studies are also presented, which focus in particular on the impact of changes in water management regime. Finally, the paper presents an assessment of the three main types of valuation methodology and a set of conclusions and recommendations for future valuation studies.
