The Iowa State Capitol Fire 1904, November 2012

The twenty-first century Iowa State Capitol contains state-of-the-art fire protection. Sprinklers and smoke detectors are located in every room and all public hallways are equipped with nearby hydrants. The Des Moines Fire Department is able to fight fires at nearly any height. However, on Monday morning, January 4, 1904, the circumstances were much different. By the beginning of 1904, the Capitol Improvement Commission had been working in the Capitol for about two years. The commissioners were in charge of decorating the public areas of the building, installing the artwork in the public areas, installing a new copper roof, re-gilding the dome, replacing windows, and connecting electrical lines throughout. Electrician H. Frazer had been working that morning in Committee Room Number Five behind the House Chamber, drilling into the walls to run electrical wires and using a candle to light his way. The investigating committee determined that Frazer had left his work area and had neglected to extinguish his candle. The initial fire alarm sounded at approximately 10 a.m. Many citizen volunteers came to help the fire department. Capitol employees and state officials also assisted in fighting the fire, including Governor Albert Cummins. The fire was finally brought under control around 6 p.m., although some newspaper accounts at the time reported that the fire continued smoldering for several days. Crampton Linley was the engineer working with the Capitol Improvement Commission. He was in the building at the time of the fire and was credited with saving the building. Linley crawled through attic areas to close doors separating wings of the Capitol, an action which smothered the flames and brought the fire under control. Sadly, Linley did not live long enough to be recognized for his heroism. The day after the fire, while examining the damage, Linley fell through the ceiling of the House Chamber and died instantly from severe head injuries. The flames had burned through the ceiling and caused much of it to collapse to the floor below, while the lower areas of the building had been damaged by smoke and water. Elmer Garnsey was the artist hired by the Capitol Improvement Commission to decorate the public areas of the building. Therefore, he seemed the logical candidate to be given the additional responsibility of redecorating the areas damaged by the fire. Garnsey had a very different vision for the decoration, which is why the House Chamber, the old Supreme Court Room, and the old Agriculture offices directly below the House Chamber have a design that is very different from the areas of the building untouched by the fire.

Sugarcane crop efficiency in two growing seasons in São Paulo State, Brazil

A conceptual framework for crop production efficiency was derived using thermodynamic efficiency concept, in order to generate a tool for performance evaluation of agricultural systems and to quantify the interference of determining factors on this performance. In Thermodynamics, efficiency is the ratio between the output and input of energy. To establish this relationship in agricultural systems, it was assumed that the input energy is represented by the attainable crop yield, as predicted through simulation models based on environmental variables. The method of FAO's agroecological zones was applied to the assessment of the attainable sugarcane yield, while Instituto Brasileiro de Geografia e Estatística (IBGE) data were used as observed yield. Sugarcane efficiency production in São Paulo state was evaluated in two growing seasons, and its correlation with some physical factors that regulate production was calculated. A strong relationship was identified between crop production efficiency and soil aptitude. This allowed inferring the effect of agribusiness factors on crop production efficiency. The relationships between production efficiency and climatic variables were also quantified and indicated that solar radiation, annual rainfall, water deficiency, and maximum air temperature are the main factors affecting the sugarcane production efficiency.

Exploration of the social dimension of corporate responsibility in a welfare state

This study focuses on corporate social responsibility (or CSR)as the latest dimension to emerge in the corporate responsibility and sustainability agenda, which in the recent past has rapidly risen to the top of the list of concerns for civil societies worldwide. Despite the continuing debates and discussions about the scope, benefits, and impacts of CSR to business and community in various sectors, levels, and types of society, many companies have moved forward to confront the opportunities and challenges of CSR. Thus, this study is about those proactive companies with a focus on the importance of CSR and its management inside and outside the company. It is an exploration and learning from the experience of Finnish companies, as well as other actors interested or involved in shaping the course of CSR, locally and globally. It also looks closely at how national culture affects the views, thinking, and management of CSR in a welfare state. This dissertation primarily draws on the analyses of information collected from a series of qualitative interviews and the existing literature in the area. This is complemented by an analysis of written and published documents on CSR from various sources. The results of the study give insightful information and detailed descriptions of a roadmap useful in learning and understanding CSR in Finnish companies. Despite the varying conceptual connotations, essential roadmap indicators point to the importance of framing CSR within the corporate responsibility concept, Finnish development and the welfare state system, globalization, stakeholders, and the pursuit of sustainable development as the main drivers of CSR, the remarkable progress of CSR in companies, and identification of key management areas and practices relevant to CSR. Similarly,the study reveals the importance of culture as essential in understanding and learning CSR. Finnish culture has a positive influence on the views, thinking, and management practices of CSR issues. Such a positive influence of culture, therefore, makes it easy for business people to discuss and understand CSR, because those CSR issues are already considered common and taken-for-granted by Finns and are implicit in the welfare state provisions. The experience of Finnish companies in implementing CSR policies in the supply chain is a concrete proactive step in advancing the message of CSR, that is, to bring companies and suppliers together to work on improving and strengthening relationships towards socially responsible practices worldwide. Such a forward step to deal with CSR issues in the supply chain reflects the companies' commitments and belief that CSR can be managed with the suppliers and gain positive benefits. Despite the problems and complexities, particularly in the global supply chain, managing CSR for Finnish companies presents new opportunities and challenges that are expected to intensify in the near future. The focus on CSR policy implementation inthe supply chain points to the importance of companies taking initiatives and forging cooperation with suppliers with the aim of addressing and improving CSR questions in the supply chains. The proactive stance of Finnish companies toward CSR is complemented by the active supporting role of important societalactors such as the government and NGOs. These actors carry out various promotional efforts and campaigns, thus bringing CSR into the mainstream of Finnish companies and strengthening the synergistic learning about CSR within the Finnish business and civil circles. The efforts of the government and NGOs to promote CSR are indicative of the importance of multipartite involvement and the emergence of better civil regulations. Likewise, their drive to learn from each other, exchange experiences, and contribute in CSR debates facilitated the evolution of CSRnetworks in the country. The results of this study add to the mounting evidence that CSR, in general, has created a new dimension in managing corporate sustainability. This study provides compelling empirical evidence and some direct quotations about CSR in the Finnish context. This information can be used to learn and gain new useful insights, approaches, and concepts for managing CSR.

Reconceptualizing Chinese state-owned entreprise in Africa : double embeddedness and localization in Ghana

Challenging the view of asymmetrical power relations between China and Africa, this thesis questions the "Chinese comparative advantages" (monolithic state power and economic advantages) of Chinese state-owned enterprises (SOEs) in Africa. It argues that the power dynamics between Chinese and African actors are dialectical and pluralistic, with localized social capital representing the true Chinese competitive advantage in Africa. Based on ethnographical fieldwork conducted in Ghana, this thesis shows that Chinese SOEs pursue their globalization in a double context - that of the deliberate "retreat" of the Chinese state, and more importantly, that of Ghanaian governance and society (characterized by political party patronage, extraversion dynamics, and worker agency). The trajectories of Chinese expatriates' expatriation/ social promotion and their SOEs' globalization/ localization are mutually influenced and reinforced. By cultivating local relationships and knowledge, a provincial Chinese SOE in Ghana can outperform a large Chinese central SOE, even if the latter has more support from the Chinese state. Moreover, the recent effort to build a "socially acceptable Chinese community" in Ghana has renewed the power dynamics between the Chinese state and the SOEs. All these observations provide for constructing a new perspective of Chinese SOEs in Africa - a "second-class" Chinese globalization - the SOEs may begin with few privileges, but promotion over time is possible. -- A contre pied des approches postulant des relations de pouvoir asymétriques entre la Chine et l'Afrique, cette thèse interroge les « avantages comparatifs chinois » (pouvoir de l'État monolithique et avantages économiques) des entreprises publiques chinoises (EPC) en Afrique. Elle soutient l'idée selon laquelle les dynamiques de pouvoir entre les acteurs chinois et africains est dialectique et pluraliste, et le capital social localisé étant le véritable avantage compétitif chinois en Afrique. S'appuyant sur un travail de terrain ethnographique au Ghana, cette thèse montre que les EPC poursuivent leur mondialisation dans un double contexte - celui de la «retraite» délibérée de l'État chinois, et, de façon plus importante, celui de la gouvernance et de la société ghanéennes (caractérisées par un clientélisme des partis politiques, une dynamique d'extraversion et le pouvoir de négociation des travailleurs). Les trajectoires d'expatriation / de promotion sociale des expatriés chinois et la mondialisation / localisation de leurs EPC s'influencent et se renforcent mutuellement. En cultivant des relations et des connaissances locales, une EPC provinciale au Ghana peut surpasser une grande EPC centrale, même si cette dernière reçoit plus de soutien de l'État chinois. En outre, les efforts récents visant à construire une «communauté chinoise socialement acceptable» au Ghana ont renouvelé la dynamique du pouvoir entre l'État chinois et les EPC. Ces observations permettent de construire une nouvelle perspective des EPC en Afrique - la globalisation chinoise de « deuxième classe » - les EPC peuvent débuter avec peu de privilèges, mais leur promotion reste possible avec le temps.

On the relationships between ultrasonic calling and anxiety-related behavior in rats

In the present review, the phenomenon of ultrasonic vocalization in rats will be outlined, including the three classes of vocalizations, namely 40-kHz calls of pups, and 22- and 50-kHz calls of juvenile and adult rats, their general relevance to behavioral neuroscience, and their special relevance to research on anxiety, fear, and defense mechanisms. Here, the emphasis will be placed on 40- and 22-kHz calls, since they are typical for various situations with aversive properties. Among other topics, we will discuss whether such behavioral signals can index a certain affective state, and how these signals can be used in social neuroscience, especially with respect to communication. Furthermore, we will address the phenomenon of inter-individual variability in ultrasonic calling and what we currently know about the mechanisms, which may determine such variability. Finally, we will address the current knowledge on the neural and pharmacological mechanisms underlying 22-kHz ultrasonic vocalization, which show a substantial overlap with mechanisms known from other research on fear and anxiety, such as those involving the periaqueductal gray or the amygdala.

In search of good relationships to music : understanding aspiration and challenge in developing music school teacher practices

This study focuses on teacher practices in publicly funded music schools in Finland. As views on the aims of music education change and broaden, music schools across Europe share the challenge of developing their activities in response. In public and scholarly debate, there have been calls for increased diversity of contents and concepts of teaching. In Finland, the official national curriculum for state-funded music schools builds on the ideal that teaching and learning should create conditions which promote ‘a good relationship to music’. The meaning of this concept has been deliberately left open in order to leave room for dialogue, flexibility, and teacher autonomy. Since what is meant by ‘good’ is not defined in advance, the notion of ‘improving’ practices is also open to discussion. The purpose of the study is to examine these issues from teachers’ point of view by asking what music school teachers aim to accomplish as they develop their practices. Methodologically, the study introduces a suggestion for building empirical research on Alperson’s ‘robust’ praxial approach to music education, a philosophical theory which is strongly committed to practitioner perspectives and musical diversity. A systematic method for analysing music education practices, interpretive practice analysis, is elaborated with support from interpretive research methods originally used in policy analysis. In addition, the research design shows how reflecting conversations (a collaborative approach well-known in Nordic social work) can be fruitfully applied in interpretive research and combined with teacher inquiry. Data have been generated in a collaborative project involving five experienced music school teachers and the researcher. The empirical material includes transcripts from group conversations, data from teacher inquiry conducted within the project, and transcripts from follow-up interviews. The teachers’ aspirations can be understood as strivings to reinforce the connection between musical practices and various forms of human flourishing such that music and flourishing can sustain each other. Examples from their practices show how the word ‘good’ receives its meaning in context. Central among the teachers’ concerns is their hope that students develop a free and sustainable interest in music, often described as inspiration. I propose that ‘good relationships to music’ and ‘inspiration’ can be understood as philosophical mediators which support the transition from an indeterminate ‘interest in music’ towards specific ways in which music can become a (co-)constitutive part of living well in each person’s particular circumstances. Different musical practices emphasise different aspects of what is considered important in music and in human life. Music school teachers consciously balance between a variety of such values. They also make efforts to resist pressure which might threaten the goods they think are most important. Such goods include joy, participation, perseverance, solid musical skills related to specific practices, and a strong sense of vitality. The insights from this study suggest that when teachers are able to create inspiration, they seem to do so by performing complex work which combines musical and educational aims and makes general positive contributions to their students’ lives. Ensuring that teaching and learning in music schools remain as constructive and meaningful as possible for both students and teachers is a demanding task. The study indicates that collaborative, reflective and interdisciplinary work may be helpful as support for development processes on both individual and collective levels of music school teacher practices.

Syntrophic relationships between algae and bacteria in a fresh-water stream and in culture /

Interactions between freshwater algae and bacteria were examined in a natural stream habitat and a laboratory model. Field observations provided circumstantial evidence, in statistical correlation for syntrophy between the microbial populations. This relation is probably subject to control by the temperature and pH of the aquatic environment. Several species of a pond community were isolated in axenic culture and tests were performed to determine the nature of mixed species interactions. Isolation procedures and field studies indicated that selected strains of Chlorella and Azotobacter were closely associated in their natural habitat. With the suspected controlling parameters, pH and temperature, held constant, mixed cultures of algae and bacteria were compared to axenic cultures of the same organisms, and a mutual stimulation of growth was observed. A mixed pure culture apparatus was designed in this laboratory to study the algal-bacterial interaction and to test the hypothesis that such an interaction may take place through a diffusable substance or through certain medium-borne conditions, Azotobacter was found to take up a Chlorella-produced exudate, to stimulate protein synthesis, to enhance chlorophyll production and to cause a numerical increase in the interacting Chlorella population. It is not clear whether control is at the environmental, cellular or genetic level in these mixed population interactions. Experimental observations in the model system, taken with field correlations allow one to state that there may be a direct relationship governing the population fluctuations of these two organisms in their natural stream surroundings.

Biogeochemistry of Paleozoic brachiopods from New York State and Ontario

A comprehensive elemental, isotopic and microstructural analyses was undertaken of brachiopod calcites from the Hamilton Group (Middle Devonian), Clinton Group (Middle Silurian) and Middle to Upper Ordovician strata of Ontario and New York State. The majority of specimens were microstructurally and chemically preserved in a pristine state, although a number of specimens show some degree of post-depositional alteration. Brachiopod calcites from the Hamilton and Clinton Groups were altered by marine derived waters whereas Trenton Group (Middle Ordovician) brachiopods altered in meteorically derived fluids. Analysis of the elemental and isotopic compositions of pristine Hamilton Group brachiopods indicates there are several chemical relationships inherent to brachiopod calcite. Taxonomic differentiation of Mg, Sr and Na contents was evident in three co-occuring species from the Hamilton Group. Mean Mg contents of pristine brachiopods were respectively Athyris spiriferoides (1309ppm), Mucrospirifer mucronatus (1035ppm) and Mediospirifer audacula (789ppm). Similarly, taxonomic differentiation of shell calcite compositions was observed in co-occuring brachiopods from the Clinton Group (Middle Silurian) and the Trenton Group (Middle Ordovician). The taxonomic control of elemental regulation into shell calcite is probably related to the slightly different physiological systems and secretory mechanisms. A relationship was observed in Hamilton Group species between the depth of respective brachiopod communities and their Mg, Sr and Na contents. These elements were depleted in the shell calcites of deeper brachiopods compared to their counterparts in shallower reaches. Apparently shell calcite elemental composition is related to environmental conditions of the depositional setting, which may have controlled the secretory regime, mineral morphology of shell calcite and precipitation rates of each species. Despite the change in Mg, Sr and Na contents between beds and formations in response to environmental conditions, the taxonomic differentiation of shell calcite composition is maintained. Thus, it may be possible to predict relative depth changes in paleoenvironmental reconstructions using brachiopod calcite. This relationship of brachiopod chemistry to depth was also tested within a transgressiveregressive (T-R) cycle in the Rochester Shale Formation (Middle Silurian). Decreasing Mg, Sr and Na contents were observed in the transition from the shallow carbonates of the Irondequoit Formation to the deeper shales of the lowest 2 m of Rochester Shale. However, no isotopic and elemental trends were observed within the entire T-R cycle which suggests that either the water conditions did not change significantly or that the cycle is illusory. A similar relationship was observed between the Fe and Mn chemistries of shell calcite and redox/paleo-oxygen conditions. Hamilton Group brachiopods analysed from deeper areas of the shelf are enriched in Mn and Fe relative to those from shallow zones. The presence of black shales and dysaerobic faunas, during deposition of the Hamilton Group, suggests that the waters of the northern Appalachian Basin were stratified. The deeper brachiopods were marginally positioned above an oxycline and their shell calcites reflect periodic incursions of oxygen depleted water. Furthermore, analysis of Dalmanella from the black shales of the Collingwood Shale (Upper Ordovician) in comparison to those from the carbonates of the Verulam Formation (Middle Ordovician) confirm the relationship of Fe and Mn contents to periodic but not permanent incursions of low oxygen waters. The isotopic compositions of brachiopod calcite found in Hamilton Group (813C; +2.5% 0 to +5.5% 0; 8180 -2.50/00 to -4.00/00) and Clinton Group (813C; +4.00/00 to +6.0; 8180; -1.8% 0 to -3.60/ 00) are heavier than previously reported. Uncorrected paleotemperatures (assuming normal salinity, 0% 0 SMOW and no fractionation effects) derived from these isotopic values suggest that the Clinton sea temperature (Middle Silurian) ranged from 18°C to 28°C and Hamilton seas (Middle Devonian) ranged between 24°C and 29°C. In addition, the isotopic variation of brachiopod shell calcite is significant and is related to environmental conditions. Within a single time-correlative shell bed (the Demissa Bed; Hamilton Group) a positive isotopic shift of 2-2.5% 0 in 013C compositions and a positive shift of 1.0-1.50/00 in 0180 composition of shell calcite is observed, corresponding with a deepening of brachiopod habitats toward the axis of the Appalachian Basin. Moroever, a faunal succession from deeper Ambocoelia dominated brachiopod association to a shallow Tropidoleptus dominated assocation is reflected by isotopic shifts of 1.0-1.50/00. Although, other studies have emphasized the significance of ±20/oo shifts in brachiopod isotopic compositions, the recognition of isotopic variability in brachiopod calcite within single beds and within depositional settings such as the Appalachian Basin has important implications for the interpretation of secular isotopic trends. A significant proportion of the variation observed isotopic distribution during the Paleozoic is related to environmental conditions within the depositional setting.

"Welcome to my life" : the experiences of single mothers who are the recipients of multiple state provided benefits

Abstract This research takes the lens of social reproduction as a starting point for an examination of the effects of recent social welfare reforms on the lives o.fsingle mothers. As the cumulative effects o.f diminishing state provided benefits take hold, tensions are heightened as single mothers internalize the insecurity of earning an income in 11 capitalist labour market, while trying to carry out all that is involved in social reproduction with inadequate means of survival. Through interviewing single mothers who are the recipients of mUltiple state provided benefits (social assistance, student loans, subsidized housing and subsidized childcare), this thesis illuminates the cOl1linued regulation of women in an effort to assure that social reproduction is occurring at the lowest cost possible. State provided benefits are set lip in such a way that it is near impossible for single mothers to make ends meet without entering the labour force or entering into co-residential relationships. This push towards the labour force and/or marriage via punitive welfare policies illuminates the devaluation of the labour that is done at home. Through interviewing 5 single mothers, I will demonstrate the extensive labour that goes into maintaining their households. In addition .J case managers are interviewed. The employees of social assistance, subsidized hOllsing, subsidized childcare and student loans, have much agency in deeming who is worthy of receiving benefits. The employees of these agencies have the ability to make these women's lives easier or more complicated by how the workers interpret the policy regulations. Social policies are of paramount importance in the quest for women's equality and thus have consequences for how women's daily lives are organized. The rules and regulations that govern the individual policies are complex and bureaucratic and have implications for the ways in which women must organize their lives in order to survive. The shifts in social policy have been guided by neo-liberal assumptions with a focus on individual responsibility and a market-modeled welfare state. The caring work that is involved in raising children to be productive in a capitalist society is ignored or devalued in current policies. The emphasis in each polic.:v is on getting women who receive benefits into the paid work force, with little facilitation or investment into the caring work these women do on a daily basis that in turn supports capitalism. Policies, such as social assistance, subsidized housing, subsidized childcare and student loans, are set up in such a way that ignores the reality of women's day-to-day lives and devalues the necessary work done at home. It takes an abundance of labour and strategizing for women to seek out necessary means of survival, labour that is amplified when a woman is dealing with mUltiple slate provided benefits.

Social competence following mild head injury and moderate traumatic brain injury: Investigating the neuropsychological relationships between arousal, social decision-making and depression

Client-directed long-term rehabilitative goals and life satisfaction following head injury emphasize the importance of social inclusion, rather than cognitive or physical, outcomes. However, very little research has explored the socio-emotional factors that pose as barriers to social reintegration following injury. This study investigates social barriers following head injury (i.e., decision-making - Iowa Gambling Task [IGT] and mood – depression) and possible amelioration of those challenges (through treatment) in both highly functioning university students with and without mild head injury (MHI) and in individuals with moderate traumatic brain injury (TBI). An arousal manipulation using emotionally evocative stimuli was introduced to manipulate the subject’s physiological arousal state. Seventy-five university students (37.6% reporting a MHI) and 11 patients with documented moderate TBI were recruited to participate in this quasi-experimental study. Those with head injury were found to be physiologically underaroused (on measures of electrodermal activation [EDA] and pulse) and were less sensitive to the negative effects of punishment (i.e., losses) in the gambling task than those without head injury, with greater impairment being observed for the moderate TBI group. The arousal manipulation, while effective, was not able to maintain a higher state of arousal in the injury groups across trials (i.e., their arousal state returned to pre-manipulation levels more quickly than their non-injured cohort), and, subsequently, a performance improvement was not observed on the IGT. Lastly, head injury was found to contribute to the relationship between IGT performance and depressive symptom acknowledgment and mood status in persons with head injury. This study indicates the possible important role of physiological arousal on socio- emotional behaviours (decision-making, mood) in persons with even mild, non-complicated head injuries and across the injury severity continuum.

The dismembered family : youth, memory, and modernity in rural southern Chile

Cette thèse traite de la supposée perte de culture politique et citoyenne que connaît le Chili de la période post-dictature. Bien qu’une telle perte soit généralement considérée comme une évidence, nous évaluons dans quelle mesure celle-ci est bien réelle en nous intéressant aux processus d’apprentissage du comportement civique de la plus jeune génération politique du pays qui a aujourd’hui atteint la vingtaine. Étant donné que les membres de cette génération étaient soit au stade de l’enfance, soit pas même nés au moment de la transition démocratique de 1990, ils ont habituellement pris connaissance des événements de répression étatique et de réconciliation démocratique par l’intermédiaire de leurs aînés. Ce phénomène est encore plus marqué dans les régions rurales du sud du pays où la majeure partie de ce que les jeunes générations savent du passé conflictuel de leur pays, incluant le colonialisme, le socialisme révolutionnaire et le fascisme, n’a pas été transmis par la communication verbale ou volontaire, mais indirectement via les habitudes et préférences culturelles qui ne manquent pas d’influencer les décisions politiques. À travers l’analyse des mécanismes de transmission inter-générationnelle de diverses perspectives d’un passé contesté, notre travail explore les processus par lesquels, à l’échelle micro, certains types de comportement politique sont diffusés au sein des familles et de petits réseaux communautaires. Ces derniers se situent souvent en tension avec les connaissances transmises dans les domaines publics, comme les écoles et certaines associations civiques. De telles tensions soulèvent d’importantes questions au sujet des inégalités de statut des membres de la communauté nationale, en particulier à une époque néolibérale où la réorganisation du fonctionnement des services sociaux et du contrôle des ressources naturelles a transformé les relations entre le monde rural pauvre et la société dominante provenant des centres urbains. Au sein de la jeune génération politique du Chili, dans quelle mesure ces perspectives situées concernant un passé pour le moins contesté, ainsi que leurs impacts sur la distribution actuelle du pouvoir dans le pays façonnent-ils des identités politiques en émergence ? Nous abordons cette question à l’aide d’une analyse ethnographique des moyens auxquels les jeunes recourent pour acquérir et exprimer des connaissances au sujet de l’histoire et de son influence latente dans la vie civique actuelle. Nos données proviennent de plus de deux années de terrain anthropologique réalisées dans trois localités du sud rural ayant été touchées par des interventions industrielles dans les rivières avoisinantes. L'une d'entre elles a été contaminée par une usine de pâte à papier tandis que les autres doivent composer avec des projets de barrage hydroélectrique qui détourneront plusieurs rivières. Ces activités industrielles composent la toile de fond pour non seulement évaluer les identités politiques, émergentes mais aussi pour identifier ce que l’apprentissage de comportement politique révèle à propos de la citoyenneté au Chili à l’heure actuelle.

Santé reproductive et santé mentale des femmes qui ont subi la violence sexuelle en temps de conflit armé : cas de la République Démocratique du Congo

Problématique : Depuis bientôt deux décennies, la République Démocratique du Congo (RDC) est le territoire d’un conflit armé qui, selon l’International Rescue Commite, aurait occasionné plus de 3 millions de décès et autant de déplacés internes. Plusieurs rapports font également cas des nombreux actes de violence sexuelle (les viols, les mutilations, l’esclavage, l’exploitation sexuelle, etc.) commis envers les filles, les femmes et dans une moindre ampleur les hommes. S’il existe un consensus sur le côté barbare des actes de violence sexuelle liés aux conflits armés, rares sont les études qui ont évalué leurs conséquences sur la santé reproductive des survivantes surtout en termes d’issues telles que les fistules, les douleurs pelviennes chroniques (DPC), le désir de rapports sexuels, le désir d’enfant et le désir d’interruption de la grossesse issue de tels actes. Par ailleurs, même si la santé mentale des populations en zones de conflit représente un sujet d’intérêt, l’impact spécifique de la violence sexuelle liée au conflit sur la santé mentale des survivantes a été peu étudié. De plus, ces travaux s’intéressent aux effets de la violence sexuelle liée au conflit sur la santé mentale et sur la santé reproductive séparément et ce, sans évaluer les relations qui peuvent exister entre ces deux dimensions qui, pourtant, s’influencent mutuellement. Aussi, l’impact social de la violence sexuelle liée au conflit, ainsi que la contribution des normes socioculturelles aux difficultés que rencontrent les survivantes, a été peu étudié. Pourtant, l’impact social de la violence sexuelle liée au conflit peut permettre de mieux comprendre comment l’expérience d’un tel acte peut affecter la santé mentale. Enfin, aucune étude n’a évalué les effets de la violence sexuelle liée au conflit en la comparant à la violence sexuelle non liée au conflit (VSNLC). Pourtant, il est reconnu qu’à de nombreux égards, la violence sexuelle liée au conflit est bien différente de la VSNLC puisqu’elle est perpétrée avec l’intention de créer le maximum d’effets adverses pour la victime et sa communauté. Objectifs : Les objectifs poursuivis dans cette thèse visent à : 1) évaluer les effets de la violence sexuelle liée au conflit sur la santé reproductive; 2) évaluer les effets de la violence sexuelle liée au conflit sur la santé mentale en termes de sévérité des symptômes de stress posttraumatique (PTSD), de sévérité des symptômes de détresse psychologique et de probabilité de souffrir de troubles mentaux communs (TMC); 3) évaluer la contribution des troubles physiques de santé reproductive, en particulier les fistules et les douleurs pelviennes chroniques (DPC), aux effets de la violence sexuelle liée au conflit sur la santé mentale; 4) évaluer la contribution de l’état de santé mentale aux effets de la violence sexuelle liée au conflit sur le désir de rapports sexuels et le désir d’enfant; et 5) étudier l’impact de la violence sexuelle liée au conflit sur le plan social ainsi que la contribution des normes socioculturelles à ses effets adverses et la façon dont ces effets pourraient à leur tour influencer la santé des femmes et leur relation avec l’enfant issu de l’acte de violence sexuelle subi. Méthodologie : Un devis mixte de nature convergente a permis de collecter des données quantitatives auprès de l’ensemble des participantes (étude transversale) et des données qualitatives sur un nombre plus restreint de femmes (étude phénoménologique). Une étude transversale populationnelle a été conduite entre juillet et août 2012 auprès de 320 femmes âgées de 15 à 45 ans habitant quatre (4) quartiers de la ville de Goma située dans la province du Nord-Kivu en RDC. Les femmes ont été recrutées à travers des annonces faites par les responsables des programmes d’alphabétisation et de résolution de conflits implantés dans les différents quartiers par le Collectif Alpha Ujuvi, une ONG locale. Les issues de santé reproductive évaluées sont : les fistules, les DPC, le désir de rapports sexuels, le désir d’enfant et le désir d’interruption de la grossesse issue d’un acte de violence sexuelle. Les variables de santé mentale d’intérêt sont : la sévérité des symptômes de détresse psychologique, la sévérité des symptômes de PTSD et la probabilité de souffrir de TMC. Pour les analyses, l’exposition a été définie en trois (3) catégories selon l’expérience passée de violence sexuelle : les femmes qui ont vécu des actes de violence sexuelle liée au conflit, celles qui ont vécu des actes de VSNLC et celles qui ont déclaré n’avoir jamais subi d’acte de violence sexuelle au cours de leur vie. Les variables de confusion potentielles mesurées sont : l’âge, le statut matrimonial, le nombre d’enfants, le niveau d’éducation le plus élevé atteint et l’occupation professionnelle. Les mesures d’associations ont été évaluées à l’aide de modèles de régressions logistiques et linéaires simples et multiples. Des tests d’interaction multiplicative et des analyses stratifiées ont été également conduits pour évaluer l’effet potentiellement modificateur de quelques variables (âge, statut matrimonial, nombre d’enfants) sur la relation entre la violence sexuelle et les variables de santé reproductive ou de santé mentale. Ces tests ont également été utilisés pour évaluer la contribution d’une variable de santé reproductive ou de santé mentale aux effets de la violence sexuelle sur l’autre dimension de la santé d’intérêt dans cette étude. Une étude phénoménologique a été conduite dans le même intervalle de temps auprès de 12 femmes ayant participé à la partie quantitative de l’étude qui ont vécu la violence sexuelle liée au conflit et ont eu un enfant issu d’une agression sexuelle. Les sujets explorés incluent : la perception de l’acte de violence sexuelle liée au conflit vécu et de la vie quotidienne par les victimes; la perception de l’acte de violence sexuelle liée au conflit par la famille et l’entourage et leurs réactions après l’agression; la perception de la grossesse issue de l’acte de violence sexuelle par la victime; la perception de l’enfant issu de la violence sexuelle liée au conflit par la victime ainsi que son entourage; les conséquences sociales de l’expérience de violence sexuelle liée au conflit et les besoins des victimes pour leur réhabilitation. Une analyse thématique avec un codage ouvert a permis de ressortir les thèmes clés des récits des participantes. Par la suite, l’approche de théorisation ancrée a été utilisée pour induire un cadre décrivant l’impact social de l’expérience de la violence sexuelle liée au conflit et les facteurs y contribuant. Résultats : Le premier article de cette thèse montre que, comparées aux femmes qui n’ont jamais vécu un acte de violence sexuelle, celles qui ont vécu la violence sexuelle liée au conflit ont une probabilité plus élevée d’avoir une fistule (OR=11.1, IC 95% [3.1-39.3]), des DPC (OR=5.1, IC 95% [2.4-10.9]), de rapporter une absence de désir de rapports sexuels (OR=3.5, IC 95% [1.7-6.9]) et une absence de désir d’enfant (OR=3.5, IC 95% [1.6-7.8]). Comparées aux mêmes femmes, celles qui ont vécu la VSNLC ont plus de probabilité de souffrir de DPC (OR=2.3, IC 95% [0.95-5.8]) et de rapporter une absence de désir d’enfant (OR=2.7, IC 95% [1.1-6.5]). Comparées aux femmes qui ont vécu la VSNLC, celles qui ont vécu la violence sexuelle liée au conflit ont également une probabilité plus élevée d’avoir une fistule (OR=9.5, IC 95% [1.6-56.4]), des DPC (OR=2.2, IC 95% [0.8-5.7]) et de rapporter une absence de désir de rapports sexuels (OR=2.5, IC 95% [1.1-6.1]). En ce qui concerne les grossesses issues des viols, comparées aux femmes qui ont vécu la VSNLC, celles qui ont vécu la violence sexuelle liée au conflit sont plus nombreuses à souhaiter avorter (55% vs 25% pour celles qui ont vécu la VSNLC). Elles sont également plus nombreuses à déclarer qu’elles auraient avorté si les soins appropriés étaient accessibles (39% vs 21% pour celles qui ont vécu la VSNLC). Le second article montre qu’en comparaison aux femmes qui n’ont jamais subi de violence sexuelle, celles qui ont vécu la violence sexuelle liée au conflit présentent des symptômes de détresse psychologique (moyennes de score respectives 8.6 et 12.6, p<0.0001) et des symptômes de PTSD (moyennes de score respectives 2.2 et 2.6, p<0.0001) plus sévères et ont plus de probabilité d’être dépistées comme un cas de TMC (30% vs 76%, p<0.0001). De plus, comparées aux femmes qui ont vécu la VSNLC, celles qui ont vécu la violence sexuelle liée au conflit présentent des symptômes de détresse psychologique (moyennes de score respectives 10.1 et 12.6, p<0.0001) et des symptômes de PTSD (moyennes de score respectives 2.2 et 2.6, p<0.0001) plus sévères et ont plus de probabilité d’être dépistées comme un cas de TMC (48% vs 76%, p<0.001). Les valeurs minimales et maximales de score de sévérité de symptômes de détresse psychologique sont de 0/12 pour les femmes qui n’ont jamais vécu de violence sexuelle, 4/19 pour celles qui ont vécu la VSNLC et de 5/18 pour celles qui ont vécu la violence sexuelle liée au confit. En ce qui concerne la sévérité des symptômes de PTSD, les scores minimal et maximal sont respectivement de 0.36/3.22, 0.41/3.41 et 0.95/3.45. Le fait d’avoir développé une fistule ou de souffrir de DPC après l’agression sexuelle augmente la force des associations entre la violence sexuelle et la santé mentale. Les femmes qui ont subi la violence sexuelle liée au conflit et qui ont souffert de fistules présentent des symptômes de détresse psychologique et de PTSD plus sévères comparées aux femmes qui ont subi la violence sexuelle liée au conflit mais n’ont pas de fistules. Les résultats sont similaires pour les femmes qui ont subi la violence sexuelle liée au conflit et qui souffrent de DPC. Des résultats complémentaires suggèrent que le statut matrimonial modifie l’effet de la violence sexuelle sur la sévérité des symptômes de détresse psychologique, les femmes divorcées/séparées et les veuves étant celles qui ont les moyennes de score les plus élevées (respectivement 11.3 et 12.1 vs 9.26 et 9.49 pour les célibataires et les mariées). Par ailleurs, la sévérité des symptômes de détresse psychologique modifie l’association entre la violence sexuelle liée au conflit et le désir d’enfant. Le troisième article montre que, sur le plan social, l’expérience de violence sexuelle liée au conflit entraine également de lourdes conséquences. Toutes celles qui ont vécu ce type d’acte décrivent leur vie de survivante et de mère d’un enfant issu d’une agression sexuelle comme difficile, oppressive, faite de peines et de soucis et sans valeur. Plusieurs facteurs influencent la description que les victimes de violence sexuelle liée au conflit font de leur vie quotidienne, et ils sont tous reliés aux normes socioculturelles qui font de la femme une citoyenne de seconde zone, ne font aucune différence entre un viol et un adultère, condamnent les victimes de violence sexuelle plutôt que leurs agresseurs, rejettent et stigmatisent les victimes de tels actes ainsi que l’enfant qui en est issu. En réponse au rejet et au manque de considération, les femmes victimes de violence sexuelle liée au conflit ont tendance à s’isoler pour éviter les insultes et à garder le silence sur leur agression. En plus, les réactions de leur entourage/communauté ont tendance à leur faire revivre l’agression sexuelle subie, autant d’éléments qui nuisent davantage à leur réhabilitation. D’autres résultats démontrent que les enfants issus d’actes de violence sexuelle liée au conflit sont également rejetés par leur communauté, leur famille adoptive ainsi que le conjoint de leur mère, ce qui affecte davantage les survivantes. Avec leurs mères, les relations développées varient entre le rejet, la résignation et l’affection. Néanmoins, ces relations sont plus souvent tendues probablement à cause de la stigmatisation de la communauté. Conclusion: La violence sexuelle liée au conflit a des effets adverses sur la santé reproductive, la santé mentale mais également sur le plan social. Ces trois dimensions sont loin d’être isolées puisque cette étude a permis de démontrer qu’elles s’influencent mutuellement. Ceci suggère que la prise en charge des victimes de violence sexuelle liée au conflit ne doit pas se concentrer sur un aspect ou un autre de la santé mais prendre en compte l’ensemble des dimensions de la femme pour offrir une aide holistique, plus adaptée et qui sera plus efficace à long terme.

Technical and scale efficiency of cassava production system in Delta State, Nigeria: an application of Two-Stage DEA approach

The present study examines the level of pure technical and scale efficiencies of cassava production system including its sub-processes (that is production and processing stages) of 278 cassava farmers/processors from three regions of Delta State, Nigeria by applying Two-Stage Data Envelopment Analysis (DEA) approach. Results reveal that pure technical efficiency (PTE) is significantly lower at the production stage 0.41 vs 0.55 for the processing stage, but scale efficiency (SE) is high at both stages (0.84 and 0.87), implying that productivity can be improved substantially by reallocation of resources and adjusting operation size. The socio-economic determinants exert differential impacts on PTE and SE at each stage. Overall, education, experience and main occupation as farmer significantly improve SE while subsistence pressure reduces it. Extension contact significantly improves SE at the processing stage but reduces PTE and SE overall. Inverse size-PTE and size-SE relationships exist in cassava production system. In other words, large/medium farms are technically and scale inefficient. Gender gap exists in performance. Male farmers are technically efficient at processing stage but scale inefficient overall. Farmers in northern region are technically efficient. Investments in education, extension services and infrastructure are suggested as policy options to improve the cassava sector in Nigeria.
