A phonological and tonal analysis of Samue using Optimality Theory

The topic of the present doctoral dissertation is the analysis of the phonological and tonal structures of a previously largely undescribed language, namely Samue. It is a Gur language belonging to the Niger-Congo language phulym, which is spoken in Burkina Faso. The data were collected during the fieldwork period in a Sama village; the data include 1800 lexical items, thousands of elicited sentences and 30 oral texts. The data were first transcribed phonetically and then the phonological and tonal analyses were conducted. The results show that the phonological system of Samue with the phoneme inventory and phonological processes has the same characteristics as other related Gur languages, although some particularities were found, such as the voicing and lenition of stop consonants in medial positions. Tonal analysis revealed three level tones, which have both lexical and grammatical functions. A particularity of the tonal system is the regressive Mid tone spreading in the verb phrase. The theoretical framework used in the study is Optimality theory. Optimality theory is rarely used in the analysis of an entire language system, and thus an objective was to see whether the theory was applicable to this type of work. Within the tonal analysis especially, some language specific constraints had to be created, although the basic Optimality Theory principle is the universal nature of the constraints. These constraints define the well-formedness of the language structures and they are differently ranked in different languages. This study gives new insights about typological phenomena in Gur languages. It is also a fundamental starting point for the Samue language in relation to the establishment of an orthography. From the theoretical point of view, the study proves that Optimality theory is largely applicable in the analysis of an entire sound system.

Vibration analysis of a power take-off line

Gear rattle is a phenomenon that occurs when idling or lightly loaded gears collide due to engine’s torque fluctuations. This behaviour is related to vibration behaviour of the transmission system. Aim of this master’s thesis is to evaluate Adams and Adams/Machinery as a simulation tools for modelling the rattle e ect in a transmission system. A case study of tractor’s power take-o driveline, suspected to be prone to rattle, is performed in this work. Modelling methods used by Adams in this type of study are presented in the theory section while simulation model build with the software during this work is presented in the results. The Machinery toolbox is used to create gears and bearings while other model components are created with standard Adams tool set. Geometries and excitations are exported from other softwares. Results were obtained from multiple variations of a base model. These result sets and literature review suggest that Adams/Machinery may not be the most suitable tool for rattle analysis. While the system behaviour was partially captured, for accurate modelling user-written routines must be used which may be more easily performed with other tools. Further research about this topic is required.

Towards a contextual understanding of B2B salespeople's selling competencies – An exploratory study among purchasing decision-makers of internationally-oriented technology firms

ABSTRACT Towards a contextual understanding of B2B salespeople’s selling competencies − an exploratory study among purchasing decision-makers of internationally-oriented technology firms The characteristics of modern selling can be classified as follows: customer retention and loyalty targets, database and knowledge management, customer relationship management, marketing activities, problem solving and system selling, and satisfying needs and creating value. For salespeople to be successful in this environment, they need a wide range of competencies. Salespeople’s selling skills are well documented in seller side literature through quantitative methods, but the knowledge, skills and competencies from the buyer’s perspective are under-researched. The existing research on selling competencies should be broadened and updated through a qualitative research perspective due to the dynamic nature and the contextual dependence of selling competencies. The purpose of the study is to increase understanding of the professional salesperson’s selling competencies from the industrial purchasing decision- makers’ viewpoint within the relationship selling context. In this study, competencies are defined as sales-related knowledge and skills. The scope of the study includes goods, materials and services managed by a company’s purchasing function and used by an organization on a daily basis. The abductive approach and ‘systematic combining’ have been applied as a research strategy. In this research, data were generated through semi- structured, person-to-person interviews and open-ended questions. The study was conducted among purchasing decision-makers in the technology industry in Finland. The branches consisted of the electronics and electro-technical industries and the mechanical engineering and metals industries. A total of 30 companies and one purchasing decision-maker from each company were purposively chosen for the sampling. The sample covers different company sizes based on their revenues, their differing structures – varying from public to family companies –that represent domestic and international ownerships. Before analyzing the data, they were organized by the purchasing orientations of the buyers: the buying, procurement or supply management orientation. Thematic analysis was chosen as the analysis method. After analyzing the data, the results were contrasted with the theory. There was a continuous interaction between the empirical data and the theory. Based on the findings, a total of 19 major knowledge and skills were identified from the buyers’ perspective. The specific knowledge and skills from the viewpoint of customers’ prevalent purchasing orientations were divided into two categories, generic and contextual. The generic knowledge and skills apply to all purchasing orientations, and the contextual knowledge and skills depend on customers’ prevalent purchasing orientations. Generic knowledge and skills relate to price setting, negotiation, communication and interaction skills, while contextual ones relate to knowledge brokering, ability to present solutions and relationship skills. Buying-oriented buyers value salespeople who are ‘action oriented experts, however at a bit of an arm’s length’, procurement buyers value salespeople who are ‘experts deeply dedicated to the customer and fostering the relationship’ and supply management buyers value salespeople who are ‘corporate-oriented experts’. In addition, the buyer’s perceptions on knowledge and selling skills differ from the seller’s ones. The buyer side emphasizes managing the subject matter, consisting of the expertise, understanding the customers’ business and needs, creating a customized solution and creating value, reliability and an ability to build long-term relationships, while the seller side emphasizes communica- tion, interaction and salesmanship skills. The study integrates the selling skills of the current three-component model− technical knowledge, salesmanship skills, interpersonal skills− and relationship skills and purchasing orientations, into a selling competency model. The findings deepen and update the content of these knowledges and skills in the B2B setting and create new insights into them from the buyer’s perspective, and thus the study increases contextual understanding of selling competencies. It generates new knowledge of the salesperson’s competencies for the relationship selling and personal selling and sales management literature. It also adds knowledge of the buying orientations to the buying behavior literature. The findings challenge sales management to perceive salespeople’s selling skills both from a contingency and competence perspective. The study has several managerial implications: it increases understanding of what the critical selling knowledge and skills from the buyer’s point of view are, understanding of how salespeople effectively implement the relationship marketing concept, sales management’s knowledge of how to manage the sales process more effectively and efficiently, and the knowledge of how sales management should develop a salesperson’s selling competencies when managing and developing the sales force. Keywords: selling competencies, knowledge, selling skills, relationship skills, purchasing orientations, B2B selling, abductive approach, technology firms

Co-operative acquisitions – the contextual factors and challenges for co-operatives when acquiring an investorowned firm

Mergers and acquisitions (M&As) have been seen as an important strategy in helping organizations to grow, gain access to new markets and resources, increase efficiency, and enable competitiveness in order to fulfil the purpose of the organization. These aspects have made M&As of central interest to academic literature. In co-operative studies mergers especially have been widely studied. The common focus of these studies is that M&As have taken place between organizations of the same form. It is noteworthy that there is a scarcity of literature concerning acquisitions between different organizational types. Moreover, M&As have not been evaluated concerning the organization’s ownership and purpose, which may be significant integration factors. The overall objective of this study is to describe and understand why co-operative organizations use acquisition as a strategic alternative. In more detail – and in order to develop understanding of the background ideals affecting the acquisition decision and the differences of organization ideals in the integration process – this study is based on a qualitative case study approach. By combining interview data gathered from the OPPohjola Group and associating the observations from various streams of research on acquisitions and management with the purpose of co-operation, and examining these issues further, the thesis contributes to the elaboration of theory in the field of the strategic management of co-operatives. The dissertation consists of two parts. The first part introduces the research topic, methods and publications, as well as discussing the overall outcomes. The second part consists of four publications that address the research questions from different viewpoints. The analyses of this dissertation indicate that, from the strategic point of view, the acquisition of an investor-owned firm by a co-operative organization may create competitive advantage for the co-operative. On the other hand, there are differences in and following from the purpose of acquirer and the acquiree that may, in such case, pose several challenges to the integration process.

Detecting Deceit – Guessing or Assessing? Study on the Applicability of Veracity Assessment Methods in Human Intelligence

Intelligence from a human source, that is falsely thought to be true, is potentially more harmful than a total lack of it. The veracity assessment of the gathered intelligence is one of the most important phases of the intelligence process. Lie detection and veracity assessment methods have been studied widely but a comprehensive analysis of these methods’ applicability is lacking. There are some problems related to the efficacy of lie detection and veracity assessment. According to a conventional belief an almighty lie detection method, that is almost 100% accurate and suitable for any social encounter, exists. However, scientific studies have shown that this is not the case, and popular approaches are often over simplified. The main research question of this study was: What is the applicability of veracity assessment methods, which are reliable and are based on scientific proof, in terms of the following criteria? o Accuracy, i.e. probability of detecting deception successfully o Ease of Use, i.e. easiness to apply the method correctly o Time Required to apply the method reliably o No Need for Special Equipment o Unobtrusiveness of the method In order to get an answer to the main research question, the following supporting research questions were answered first: What kinds of interviewing and interrogation techniques exist and how could they be used in the intelligence interview context, what kinds of lie detection and veracity assessment methods exist that are reliable and are based on scientific proof and what kind of uncertainty and other limitations are included in these methods? Two major databases, Google Scholar and Science Direct, were used to search and collect existing topic related studies and other papers. After the search phase, the understanding of the existing lie detection and veracity assessment methods was established through a meta-analysis. Multi Criteria Analysis utilizing Analytic Hierarchy Process was conducted to compare scientifically valid lie detection and veracity assessment methods in terms of the assessment criteria. In addition, a field study was arranged to get a firsthand experience of the applicability of different lie detection and veracity assessment methods. The Studied Features of Discourse and the Studied Features of Nonverbal Communication gained the highest ranking in overall applicability. They were assessed to be the easiest and fastest to apply, and to have required temporal and contextual sensitivity. The Plausibility and Inner Logic of the Statement, the Method for Assessing the Credibility of Evidence and the Criteria Based Content Analysis were also found to be useful, but with some limitations. The Discourse Analysis and the Polygraph were assessed to be the least applicable. Results from the field study support these findings. However, it was also discovered that the most applicable methods are not entirely troublefree either. In addition, this study highlighted that three channels of information, Content, Discourse and Nonverbal Communication, can be subjected to veracity assessment methods that are scientifically defensible. There is at least one reliable and applicable veracity assessment method for each of the three channels. All of the methods require disciplined application and a scientific working approach. There are no quick gains if high accuracy and reliability is desired. Since most of the current lie detection studies are concentrated around a scenario, where roughly half of the assessed people are totally truthful and the other half are liars who present a well prepared cover story, it is proposed that in future studies lie detection and veracity assessment methods are tested against partially truthful human sources. This kind of test setup would highlight new challenges and opportunities for the use of existing and widely studied lie detection methods, as well as for the modern ones that are still under development.

In distrust we trust : analysis of academic apocalypse

The paper concentrates on trust as a research topic that receives increasing attention from the side of different social disciplines. The author of this thesis attempts to identify the reasons of this phenomenon, as well as the decline in usage of the concepts conveying a congenial idea, such as, solidarity, cooperation, social cohesion, social capital or connectedness. The key hypotheses, such as paradigmatic change within the social sciences, emergence of risk society, proliferation of the postmodem condition, new infonnation and communication technologies and the crisis of democracy are considered through the works of the authors who now mainly responsible for the shaping of the discourse of trust. The concepts of Luhmann, Putnam, Sztompka, Fukuyama and Hardin are analyzed from an epistemological viewpoint in its ontological and political implications. The primary goal of the paper is to overview trust from the methodological viewpoint, illustrating the limitations of the concept as a research strategy as weII as it advantages in the epoch when the social sciences acquire a status of moral disciplines.

From protest to powerlessness : a Marxist analysis of the Ontario NDP /

Using Marxist state theory as an analytical framework, this thesis explains the problems faced by the Ontario New Democratic Party government (1990-1995) in implementing a social democratic agenda. Not only was the government constrained in its ability to implement progressive policy, but it was also pushed to implement a Social Contract (involving legislated wage cuts to public sector employees) that alienated the party's base of support, making it more difficult for the party to organize in the future. Although this study relies predominantly on a reinterpretation of existing research on the topic, some primary research is used in the analysis, including interviews with members of the labour movement and former MPPs and analysis of the news media's treatment of the party/ government. Historical and class analytical perspectives are used to explain the evolution of the ONDP's structure and policies, as well as to assess the relative strength of the working class and its ability to support a social democratic political agenda. It was found that the ONDP' s unwillingness to develop a long term plan for social democracy, and its inability to act as a mass party or to build a strong working class movement, made it more difficult for the party to succeed when it formed the government. Moreover, the class nature of the capitalist state, along with pressure exerted by a well mobilized capitalist class, worked to limit the government' s options.

The analysis of humour

INTRODUCTION Theories of humour are traditionally divided into two classes: superiority or relief theories, and incongruity or ambiguity theories. As their names imply, the former tend to ascribe amusement primarily to a particular attitude of mind, while the latter account for it by describing its objects as having a particular quality. Enjoyment as an attitude is always a response to an object present to the mind or feelings. If, then, enjoyment in amusement is identical with feelings of superiority or relief, its objects must always display characteristics of inferiority or inhibition. But the enjoyment of humour seems to be distinguishable from a reaction to particular kinds of topic, and from any personal relation felt between the subject and the objects of his amusement. Incongruity theories do not explicitly ascribe the enjoyment of humour to a particular range of topics.

A multidimensional measurement approach and analysis of children's motivation for reading, attributional style, and reading achievement

The present study investigates the usefulness of a multi-method approach to the measurement of reading motivation and achievement. A sample of 127 elementary and middle-school children aged 10 to 14 responded to measures of motivation, attributions, and achievement both longitudinally and in a challenging reading context. Novel measures of motivation and attributions were constructed, validated, and utilized to examine the relationship between ~ motivation, attributions, and achievement over a one-year period (Study I). The impact of classroom contexts and instructional practices was also explored through a study of the influence of topic interest and challenge on motivation, attributions, and persistence (Study II), as well as through interviews with children regarding motivation and reading in the classroom (Study III). Creation and validation of novel measures of motivation and attributions supported the use of a self-report measure of motivation in situation-specific contexts, and confirmed a three-factor structure of attributions for reading performance in both hypothetical and situation-specific contexts. A one-year follow up study of children's motivation and reading achievement demonstrated declines in all components of motivation beginning at age 10 through 12, and particularly strong decreases in motivation with the transition to middle school. Past perceived competence for reading predicted current achievement after controlling for past achievement, and showed the strongest relationships with reading-related skills in both elementary and middle school. Motivation and attributions were strongly related, and children with higher motivation Fulmer III displayed more adaptive attributions for reading success and failure. In the context of a developmentally inappropriate challenging reading task, children's motivation for reading, especially in terms of perceived competence, was threatened. However, interest in the story buffered some ofthe negative impacts of challenge, sustaining children's motivation, adaptive attributions, and reading persistence. Finally, children's responses during interviews outlined several emotions, perceptions, and aspects of reading tasks and contexts that influence reading motivation and achievement. Findings revealed that children with comparable motivation and achievement profiles respond in a similar way to particular reading situations, such as excessive challenge, but also that motivation is dynamic and individualistic and can change over time and across contexts. Overall, the present study outlines the importance of motivation and adaptive attributions for reading success, and the necessity of integrating various methodologies to study the dynamic construct of achievement motivation.

Search engine advertising in web retailing : an efficiency analysis

This study examines the efficiency of search engine advertising strategies employed by firms. The research setting is the online retailing industry, which is characterized by extensive use of Web technologies and high competition for market share and profitability. For Internet retailers, search engines are increasingly serving as an information gateway for many decision-making tasks. In particular, Search engine advertising (SEA) has opened a new marketing channel for retailers to attract new customers and improve their performance. In addition to natural (organic) search marketing strategies, search engine advertisers compete for top advertisement slots provided by search brokers such as Google and Yahoo! through keyword auctions. The rationale being that greater visibility on a search engine during a keyword search will capture customers' interest in a business and its product or service offerings. Search engines account for most online activities today. Compared with the slow growth of traditional marketing channels, online search volumes continue to grow at a steady rate. According to the Search Engine Marketing Professional Organization, spending on search engine marketing by North American firms in 2008 was estimated at $13.5 billion. Despite the significant role SEA plays in Web retailing, scholarly research on the topic is limited. Prior studies in SEA have focused on search engine auction mechanism design. In contrast, research on the business value of SEA has been limited by the lack of empirical data on search advertising practices. Recent advances in search and retail technologies have created datarich environments that enable new research opportunities at the interface of marketing and information technology. This research uses extensive data from Web retailing and Google-based search advertising and evaluates Web retailers' use of resources, search advertising techniques, and other relevant factors that contribute to business performance across different metrics. The methods used include Data Envelopment Analysis (DEA), data mining, and multivariate statistics. This research contributes to empirical research by analyzing several Web retail firms in different industry sectors and product categories. One of the key findings is that the dynamics of sponsored search advertising vary between multi-channel and Web-only retailers. While the key performance metrics for multi-channel retailers include measures such as online sales, conversion rate (CR), c1ick-through-rate (CTR), and impressions, the key performance metrics for Web-only retailers focus on organic and sponsored ad ranks. These results provide a useful contribution to our organizational level understanding of search engine advertising strategies, both for multi-channel and Web-only retailers. These results also contribute to current knowledge in technology-driven marketing strategies and provide managers with a better understanding of sponsored search advertising and its impact on various performance metrics in Web retailing.

Electrophysiological constituents of the P100 and N170 ERP complex: De-constructing of face processing using independent component analysis and robust estimation.

The initial timing of face-specific effects in event-related potentials (ERPs) is a point of contention in face processing research. Although effects during the time of the N170 are robust in the literature, inconsistent effects during the time of the P100 challenge the interpretation of the N170 as being the initial face-specific ERP effect. The interpretation of the early P100 effects are often attributed to low-level differences between face stimuli and a host of other image categories. Research using sophisticated controls for low-level stimulus characteristics (Rousselet, Husk, Bennett, & Sekuler, 2008) report robust face effects starting at around 130 ms following stimulus onset. The present study examines the independent components (ICs) of the P100 and N170 complex in the context of a minimally controlled low-level stimulus set and a clear P100 effect for faces versus houses at the scalp. Results indicate that four ICs account for the ERPs to faces and houses in the first 200ms following stimulus onset. The IC that accounts for the majority of the scalp N170 (icNla) begins dissociating stimulus conditions at approximately 130 ms, closely replicating the scalp results of Rousselet et al. (2008). The scalp effects at the time of the P100 are accounted for by two constituent ICs (icP1a and icP1b). The IC that projects the greatest voltage at the scalp during the P100 (icP1a) shows a face-minus-house effect over the period of the P100 that is less robust than the N 170 effect of icN 1 a when measured as the average of single subject differential activation robustness. The second constituent process of the P100 (icP1b), although projecting a smaller voltage to the scalp than icP1a, shows a more robust effect for the face-minus-house contrast starting prior to 100 ms following stimulus onset. Further, the effect expressed by icP1 b takes the form of a larger negative projection to medial occipital sites for houses over faces partially canceling the larger projection of icP1a, thereby enhancing the face positivity at this time. These findings have three main implications for ERP research on face processing: First, the ICs that constitute the face-minus-house P100 effect are independent from the ICs that constitute the N170 effect. This suggests that the P100 effect and the N170 effect are anatomically independent. Second, the timing of the N170 effect can be recovered from scalp ERPs that have spatio-temporally overlapping effects possibly associated with low-level stimulus characteristics. This unmixing of the EEG signals may reduce the need for highly constrained stimulus sets, a characteristic that is not always desirable for a topic that is highly coupled to ecological validity. Third, by unmixing the constituent processes of the EEG signals new analysis strategies are made available. In particular the exploration of the relationship between cortical processes over the period of the P100 and N170 ERP complex (and beyond) may provide previously unaccessible answers to questions such as: Is the face effect a special relationship between low-level and high-level processes along the visual stream?

On the health and wellbeing of single working women without children : an analysis of scientific and lay discourse

Cette thèse examine la façon dont on interprète la santé et le bien-être des travailleuses célibataires et sans enfant au sein de deux types de récits : ceux provenant d’études publiées dans des périodiques (récits scientifiques) et ceux provenant d’entrevues qualitatives avec des membres de ce groupe (récits profanes). Sur le plan démographique, leur nombre est significatif; elles représentent 28% des employées canadiennes. Par contre, leur santé/bien-être est peu visible dans les écrits de recherche. Dans les sciences sociales, plusieurs études portent sur l’expérience parfois éprouvante d’être un adulte célibataire vivant dans une culture orientée sur le couple et la famille. Elles mettent l’accent sur le stigma associé à ce statut. Certains suggèrent même que les pratiques de recherche peuvent contribuer à la perpétuation de représentations négatives à l’égard des célibataires. En ayant un profil qui pourrait être symbolique d’une déviation vis-à-vis des attentes normatives entourant la vie de couple ou de famille, les travailleuses célibataires et sans enfant semblent un point de repère utile pour évaluer cette dernière possibilité. S’attarder autant aux récits scientifiques que profanes permettrait d’explorer les tensions et convergences entre eux. Suivant cet objectif, un échantillon de 32 articles scientifiques et de 22 retranscriptions d’entrevues ont été analysés selon une approche d’analyse de discours guidée par les concepts de répertoire interprétatif (une façon cohérente d’aborder un sujet donné) et de position du sujet (une identité mise en évidence par une façon de parler ou d’écrire). Trois articles ont émergé de cette recherche. Suite à une analyse des thèmes communs utilisés dans l’interprétation de la santé/du bien-être du groupe en question, un répertoire interprétatif surnommé la famille comme référence a été identifié. Ce répertoire expliquerait notamment la tendance observée d’expliquer leur santé/bien-être en référant aux états et aux charactéristiques d’être parent ou partenaire. Cette pratique peut avoir l’effet de voiler leur vie privée ou de la construire comme étant relativement appauvrie. L’article 2 examine comment les membres de ce groupe construisent leur propre bien-être. Il identifie la notion d’équilibre entre plusieurs sphères de vie et une identité de femme dynamique comme éléments centraux aux récits sur leur bien-être. Ces derniers vont à l’encontre de la perception des célibataires ou des personnes sans enfant comme ayant des vies moins épanouies ou enrichies et qui ne sont pas touchées par des questions de conciliation travail-vie personnelle. Le troisième article rassemble les deux types de récits autour des sujets de l’emploi et du statut de célibataire en lien avec le bien-être. Il met en évidence de nombreuses similarités et divergences, et théorise la fonction de ces diverses constructions. En conclusion, j’avance qu’une perspective plus critique face au statut de couple ou familial et de ses aspects normatifs pourrait offrir à la recherche en santé publique un point de réflexivité à développer davantage.

Contexte de genre, autonomie des femmes et utilisation des services de santé maternelle en milieu rural africain : analyse par modèles d’équations structurelles

La vie des femmes du continent africain et de leurs enfants continue d’être mise en danger lors de chaque accouchement car les risques de décès maternels et infantiles sont encore très élevés. Il est estimé chaque année à environ le quart du million le nombre de décès maternel et de près de quatre millions celui des enfants de moins de cinq ans. La comparaison de la situation sanitaire avec d’autres contextes permet de mieux cerner l’ampleur du problème : en Afrique sub-Saharienne, le risque de décès lié à la grossesse est de l’ordre de 1 pour 31, alors qu’il n’est que de 1 pour 4300 dans les pays industrialisés. Cette situation est évitable et, le plus souvent, résulte de la sous ou non-utilisation des services de santé maternelle, du manque de structures adéquates de soins ou de personnel de santé qualifié. Notre thèse cherche à comprendre la manière dont les inégalités de genre au sein du ménage et dans la communauté renforcent les inégalités quant à l’utilisation des services de santé maternelle, ainsi qu’aux relations empiriques qui lient les différents recours aux soins. Concrètement, elle vise à 1) proposer une mesure des normes de genre favorables à la violence contre les femmes et à analyser son influence sur leur prise de décision au sein du ménage, 2) analyser simultanément l’influence de ces normes et de l’autonomie des femmes sur le recours aux soins prénatals et à l’accouchement assisté et finalement, 3) cerner l’influence des soins prénatals sur le recours à l’accouchement assisté. Chacun de ces objectifs se heurte à un problème méthodologique substantiel, soit de mesure ou de biais de sélection, auxquels l’approche par modèles d’équations structurelles que nous avons adoptée permet de remédier. Les résultats de nos analyses, présentés sous forme d’articles scientifiques, s’appuient sur les données issues des Enquêtes Démographiques et de Santé (EDS) du Ghana, du Kenya, de l’Ouganda et de la Tanzanie et concernent les femmes vivant en milieu rural. Notre premier article propose une mesure des normes de genre et, plus exactement, celles liées à la violence contre les femmes en recourant à l’approche des variables latentes. Les cinq questions des EDS relatives à l’attitude des femmes sur la légitimation de la violence ont permis de saisir cette mesure au niveau contextuel. Les résultats suggèrent d’une part que cette mesure a de bons critères de validité puisque l’Alpha de Cronbach varie de 0.85 pour le Kenya à 0.94 pour le Ghana; les chi-deux sont non significatifs partout; le RMSEA est en dessous de 0.05; le CFI supérieur à 0.96 et les saturations sont pour la plupart supérieures à 0.7 dans tous les pays. D’autre part, à l’aide du modèle d’équations structurelles multiniveaux, nous avons trouvé qu’au-delà de leur propre attitude envers la violence contre les femmes, celles qui vivent dans un milieu où les normes de genres sont plus favorables à la violence ont plus de chances d’être de faible autonomie ou sans autonomie (comparativement à forte autonomie) dans l’ensemble des pays étudiés. Le second article documente l’influence des inégalités de genre, cernées au niveau contextuel par les normes favorables à la violence contre les femmes et au niveau individuel par l’autonomie de prise de décision au sein du ménage, sur la survenue des soins prénatals au cours du premier trimestre et sur les recours à au moins 4 consultations prénatales et à l’accouchement assisté. En utilisant également les modèles d’équations structurelles multiniveaux sur les mêmes données du premier article, nous constatons que chacune de ces variables dépendantes est fortement influencée par la grappe dans laquelle la femme vit. En d’autres mots, son lieu de résidence détermine le comportement de santé maternelle que l’on adopte. De même, en contrôlant pour les autres variables explicatives, nos résultats montrent que les femmes qui vivent dans un milieu où les normes de genre liées à la violence contre les femmes sont élevées ont, en moyenne, une plus grande chance de ne pas accoucher auprès d’un personnel qualifié au Ghana et en Ouganda, de ne pas débuter leurs soins prénatals dans le premier trimestre dans les mêmes pays, et de ne pas recourir à au moins quatre consultations prénatales en Tanzanie. Par contre, cette variable contextuelle n’influence pas significativement le recours aux soins de santé maternelle au Kenya. Enfin, les résultats montrent que les normes de genre favorables à la violence contre les femmes sont plus déterminantes pour comprendre le recours aux soins de santé maternelle dans les pays étudiés que l’autonomie de prise de décision de la femme. Dans le cadre du troisième et dernier article empirique de la thèse, nous nous sommes intéressés à l’importance des soins prénatals dans le processus de recours à l’accouchement assisté et à la place du contenu des soins reçus avant l’accouchement dans cette relation. Cet article met en exergue l’existence de biais d’endogénéité au Kenya et en Tanzanie, où sans sa prise en compte, l’effet des soins prénatals sur le recours à l’accouchement auprès d’un personnel qualifié serait fortement biaisé. De plus, il ressort qu’à l’exception du Ghana et dans une moindre mesure de la Tanzanie, cet effet est totalement médiatisé par le contenu des soins prénatals que les femmes reçoivent. L’article met ainsi en relief le rôle des prestataires de soins qui pour atteindre plus efficacement les populations doivent agir en tant que leaders au sein de leur communauté.
