ResumoEste artigo tem o propósito de esclarecer os vínculos da corrente filosófica Fenomenologia com a metodologia de pesquisa fenomenológica - a Rede de Significação, que perpassa princípios fenomenológicos e a elaboração de um pensar sobre a ciência da linguagem, apresentando um modo de compreendê-la ao inspirar-se em pensamentos merleau-pontyanos e na aplicação destes em contextos de pesquisa que tomam depoimentos como sua matéria-prima, ou seja, como o pré-reflexivo da pesquisa. Com os exemplos de pesquisa já concluídas na região de inquérito da Educação Matemática que utilizaram a metodologia apresentada, pretende-se mostrar o alcance e abrangência do método para essa área. O texto trata ainda de alguns aspectos do relacionamento do fazer do pesquisador com o método em questão. E consagra o método como uma hermenêutica fenomenológica de vivências, via linguagem, ao buscar compreensões que põem à mostra o sentido do fenômeno pesquisado.Palavras-chave: Fenomenologia; Linguagem, Rede de Significação, Pesquisa em Educação Matemática.AbstractThis article aims to clarify the bonds between the philosophical current, Phenomenology, and the phenomenological research methodology - the Network of Meanings, which crisscrosses the phenomenological principles, the elaboration of a thinking about the science of language, presenting a way of assuming it inspired by Merleau-Pontyan thoughts and applying them in research contexts that take testimonies as their raw material, i.e., as a pre-reflective action of the research. With the research examples already completed in the mathematics education inquiry region that used the methodology presented, we intend to show the scope of the method for this area. The text also deals with some aspects of the relationship between the researcher's doing and the method at stake, which is recognised as a phenomenological hermeneutic of lived experiences through language when searching for understandings that show the meaning of the phenomenon researched.Keywords: Phenomenology; Language, Network of Meanings, Research in Mathematics EducationResumenEste artículo tiene como objetivo esclarecer los vínculos de la corriente filosófica Fenomenología con la metodología de investigación fenomenológica - la Red de Significación, que recorre principios fenomenológicos, la elaboración de un pensamiento sobre la ciencia del lenguaje, presentando una forma de comprenderla inspirándose en los pensamientos de Merleau-Ponty y aplicándolos en contextos de investigación que toman los testimonios como materia prima, es decir, como prerreflexión de la investigación.

This narrative aims to explore the meaning and lived experiences of marriage that a unique immigrant population—“foreign brides” in Taiwan—possesses. This convergence narrative illustrates the dynamics and complexity of mail-order marriage and women's perseverance in a cross-cultural context. The relationship between marriage, race, and migration is analyzed. This narrative is comprised of and intertwined by two story lines. One is the story of two “foreign brides” in Taiwan. The other is my story about my cross-cultural relationship. All the dialogues are generated by 25 interviews of “foreign brides” in Taiwan and my personal experience.

The Relationship

This chapter focuses on sex/uality in the context of so-called new media and, specifically, digital discourse: technologically mediated linguistic or communicative practices, and mediatized representations of these practices. To help think through the relationship among sex, discourse, and (new) media, the discussion focuses on sexting and two instances of sexting “scandals” in the news. Against this backdrop, the chapter sets out four persistent binaries that typically shape public and academic writing about sex/uality and especially digital sex/uality: new-old, mediation-mediatization, private/real-public/fake, and personal-political. These either-or approaches are problematic, because they no longer account for the practical realities and lived experiences of both sex and media. Scholars interested in digital sex/uality are advised to adopt a “both-and” approach in which media (i.e., digital technologies and The Media) both create pleasurable, potentially liberating opportunities to use our bodies (sexually or otherwise) and simultaneously thwart us, shame us, or shut us down. In this sense, there is nothing that is really “new” after all.

Analogue material with appropriate properties is of great importance to the reliability of geomechanical model test, which is one of the mostly used approaches in field of geotechnical research. In this paper, a new type of analogue material is developed, which is composed of coarse aggregate (quartz sand and/or barite sand), fine aggregate (barite powder), and cementitious material (anhydrous sodium silicate). The components of each raw material are the key influencing factors, which significantly affect the physical and mechanical parameters of analogue materials. In order to establish the relationship between parameters and factors, the material properties including density, Young’s modulus, uniaxial compressive strength, and tensile strength were investigated by a series of orthogonal experiments with hundreds of samples. By orthogonal regression analysis, the regression equations of each parameter were obtained based on experimental data, which can predict the properties of the developed analogue materials according to proportions. The experiments and applications indicate that sodium metasilicate cemented analogue material is a type of low-strength and low-modulus material with designable density, which is insensitive to humidity and temperature and satisfies mechanical scaling criteria for weak rock or soft geological materials. Moreover, the developed material can be easily cast into structures with complex geometry shapes and simulate the deformation and failure processes of prototype rocks.

The Relationship

In this paper, we explore, name, and unpack the possibilities that printmaking, as an art form, holds in visual narrative inquiry. We also explore the relationship between visual narrative inquiry and narrative inquiry, a relational qualitative research methodology that attends to experiences. Drawing on two different ongoing narrative inquiry studies, where we engage with either trans young adults or refugee families from Syria with pre-school children, we explore how printmaking practices facilitate processes of inquiry. The etymology of the word “frame” helps us understand framing as a process that is future oriented and reflects a sense of doing, making, or preforming. In this way, framing allows us to see otherwise, to respond to and with participants, and to engage with experiences in ways that open new possibilities of inquiry.

The content of polyphenols in chocolate depends on many factors related to the properties of raw material and manufacturing parameters. The trend toward developing chocolates made from unroasted cocoa beans encourages research in this area. In addition, modern customers attach great importance to how the food they consume benefits their bodies. One such benefit that consumers value is the preservation of natural antioxidant compounds in food products (e.g., polyphenols). Therefore, in our study we attempted to determine the relationship between variable parameters at the conching stage (i.e., temperature and time of) and the content of dominant polyphenols (i.e.,catechins, epicatechins, and procyanidin B2) in chocolate milk mass (CMM) obtained from unroasted cocoa beans. Increasing the conching temperature from 50 to 60 °C decreased the content of three basic flavan-3-ols. The highest number of these compounds was determined when the process was carried out at 50 °C. However, the time that caused the least degradation of these compounds differed. For catechin, it was 2 h; for epicatechin it was 1 h; and for procyanidin it was 3 h. The influence of both the temperature and conching time on the rheological properties of chocolate milk mass was demonstrated. At 50 °C, the viscosity and the yield stress of the conched mass showed its highest value.

DHA/EPA ethyl ester is mainly used in the treatment of arteriosclerosis and hyperlipidemia. In this study, DHA+EPA ethyl ester was synthesized via lipase-catalyzed acidolysis of ethyl acetate (EA) with DHA+EPA concentrate in n-hexane using Novozym® 435. The DHA+EPA concentrate (in free fatty acid form), contained 54.4% DHA and 16.8% EPA, was used as raw material. A central composite design combined with response surface methodology (RSM) was used to evaluate the relationship between substrate concentrations and initial rate of DHA+EPA ethyl ester production. The results indicated that the reaction followed the ordered mechanism and as such, the ordered mechanism model was used to estimate the maximum reaction rate (Vmax) and kinetic constants. The ordered mechanism model was also combined with the batch reaction equation to simulate and predict the conversion of DHA+EPA ethyl ester in lipase-catalyzed acidolysis. The integral equation showed a good predictive relationship between the simulated and experimental results. 88–94% conversion yields were obtained from 100–400 mM DHA+EPA concentrate at a constant enzyme activity of 200 U, substrate ratio of 1:1 (DHA+EPA: EA), and reaction time of 300 min.

The Relationship

This paper traces the history of the relationship between Africa and the West since their first contact brought about by the outward thrust of the West, under the impetus of rising capitalism, in search of cheap labour and cheap raw material for its industries and expanding markets for its industrial products, both of which could be better ensured through domination and exploitation. The paper identifies five successive stages that African political economy has passed through under the impact of this relationship, each phase qualitatively different from the other but all having the common characteristic of domination-dependence syndrome, and each phase having been dictated by the dynamics of capitalism in different eras and by the dominant forces in the changing international system. Its finding is that the way to the latest stage, the dependency phase, was paved by the progressive proletarianization of the African peoples and the maintenance of an international peonage system. It ends by indicating the direction in which Africa can make a beginning to break out of dependency and achieve liberation.

successful design of folding bicycle should take into account the function, material properties, and fabrication process. There are some other factors that should be considered in anticipating the behavior of materials for folding bicycle. In order to understand the relationship between material properties and design of a folding bicycle and also for the future direction in new materials with new design, a comprehensive study on the design under different conditions are essential. Therefore, a systematic study on the relationship between material properties and design for folding bicycle has been performed. The advantages and disadvantages matrix between conventional bicycle and folding bicycle is presented for better understanding of the materials properties and design. It was found that the materials properties of the folding bicycle frame such as fatigue and tensile strength are the important properties for the better performance of the frame. The relationship between materials properties and design is not straight forward because the behavior of the material in the finished product could be different from that of the raw material. The swing hinge technique could be a better technique in the design for the folding bicycle frame.

This chapter outlines the rationale behind conducting repeat interviews with out-of-work benefit claimants in an effort to better understand lived experiences of welfare reform. It introduces readers to the political and theoretical context, and highlights the value in employing social citizenship as a theoretical lens in order to tease out citizenship from above and below. The recent context of welfare reform in the UK is also introduced, highlighting the extent to which successive rounds of welfare reform have cumulatively reworked the relationship between the citizen and the state. The research on which this book is based is detailed, and the value in working through and across time by taking a qualitative longitudinal approach highlighted.

Using poetry to engage the voices of women and girls in research

This chapter considers poetry as a creative or arts-based method within social research. It argues that poetry as a research methodology can elicit thoughts, feelings, and emotions, and can give a platform for marginalised voices, such as women and girls, as it enables those silenced voices to be heard — and heard loudly. Poetry offers one way to capture the knowledge held in communities, particularly among those whose voices have been traditionally marginalised, like young people and women. Poetry provides us with a different lens for making sense of everyday interactions, contradictions, and conflicts. Poetry allows us to express different perspectives of our lived experiences — a mosaic of autonomous voices freed through poetry.
