The aim of this research was to explore how issues of power manifest themselves in bringing up children at home. The starting point for the study was a phenomenon centered, power focused, and theoretically orientated view which also included an empirical part as well. The most common aim of the research was to find out and theoretize of power which is suitable for bringing up children at home. Power was defined and researched on the basis of existing power theories, mostly those presented in anglo-american research on power. For closer investigation I chose the most common categorizations and theories of power, namely, the nature of power, the four dimensions of power, and forms of power. The empirical part of the research consisted of 22 thematic interviews with mothers, fathers and 14 – 16-year-old teenagers from 11 different families. The interviewees were found through snowball sampling. The questions for the interviews were based on power theories. The result of the research was that the most common categorizations and theories of power were useful but not satisfactory in the study of power in bringing up children at home. The nature of authority in bringing up children at home appears to have same characteristics as the categorization of authority put forward by Weber but in addition it included extra categories called moral authority and ontological-existential authority. Theoretically the most challenging problem concerns the conflict between modern and postmodern views of power. None of them alone is able to describe power in bringing up children at home. The best solution appeared to be to add an assumption about the inner relation to the modern power view and an assumption about the Popperian three worlds to the postmodern view of power. The relationship between the parent and the child is necessary the inner power relation where the relation itself modifies the parties’ identities. In that case positive and productive elements are also included in the power relationship. Parents use many forms of power in bringing up children at home. Manipulative and violent forms of power are not justifiable but other forms of power and their open exercise is sometimes necessary. The important criteria to use in order to determine the most suitable forms of power and the most appropriate ways of exercising that power is to see how they improve the development of the identity and internalization of values of the child. An ethically justified exercise of power in bringing up children at home is based on a dialogical, pedagogical relationship between the parent and the child, focuses on the relationship between the parent and the child, orientates itself further than present, aspires to promote the good of the child, and comes true in a caring atmosphere.

Shifting the Focus. Incorporating knowledge about Aboriginal engineering into main stream content

BACKGROUND OR CONTEXT The concept of 'Aboriginal engineering' has had little exposure in conventional engineering education programs, despite more than 40,000 years of active human engagement with the diverse Australian environment. The work reported in this paper began with the premise that Indigenous Student Support Through Indigenous Perspectives Embedded in Engineering Curricula (Goldfinch, et al 2013) would provide a clear and replicable means of encouraging Aboriginal teenagers to consider a career in engineering. Although that remains a key outcome of this OLT project, the direction taken by the research had led to additional insights and perspectives that have wide implications for engineering education more generally. There has only been passing reference to the achievements of Aboriginal engineering in current texts, and the very absence of such references was a prompt to explore further as our work developed. PURPOSE OR GOAL Project goals focused on curriculum-based change, including development of a model for inclusive teaching spaces, and study units employing key features of the model. As work progressed we found we needed to understand more about the principles and practices informing the development of pre-contact Aboriginal engineering strategies for sustaining life and society within the landscape of this often harsh continent. We also found ourselves being asked 'what engineering did Aboriginal cultures have?' Finding that there are no easy-to- access answers, we began researching the question, while continuing to engage with specific curriculum trials. APPROACH Stakeholders in the project had been identified as engineering educators, potential Aboriginal students and Aboriginal communities local to Universities involved in the project. We realised, early on, that at least one more group was involved - all the non-Aboriginal students in engineering classes. This realisation, coupled with recognition of the need to understand Aboriginal engineering as a set of viable, long term practices, altered the focus of our efforts. Rather than focusing primarily on finding ways to attract Aboriginal engineering students, the shift has been towards evolving ways of including knowledge about Aboriginal practices and principles in relevant engineering content. DISCUSSION This paper introduces the model resulting from the work of this project, explores its potential influence on engineering curriculum development and reports on implementation strategies. The model is a static representation of a dynamic and cyclic approach to engaging with Aboriginal engineering through contact with local communities in regard to building knowledge about the social beliefs underlying Aboriginal engineering principles and practices. Ways to engage engineering educators, students and the wider community are evolving through the continuing work of the project team and will be reported in more detail in the paper. RECOMMENDATIONS/IMPLICATIONS/CONCLUSION While engineering may be considered by some to be agnostic in regard to culture and social issues, the work of this project is drawing attention to the importance of including such issues into curriculum materials at a number of levels of complexity. The paper will introduce and explore the central concepts of the research completed to date, as well as suggesting ways in which engineering educators can extend their knowledge and understanding of Aboriginal engineering principles in the context of their own specialisations.

Correlación entre la personalidad y los factores de la Teoría del Comportamiento Planeado (TCP) en adolescentes escolarizados de 11-19 años del Caribe Colombiano

The increasing rate of pregnancies in teenagers and the high incident of the infections of sexual transmission (HIV/ AIDS, for example), these are health related issues (and especially the sexual and reproductive health), which have received great attention on the part of investigators and of the public opinion in general. Recently, there has been evidenced that teenagers carry out very easily risk sexual behaviors, and those who have not presented the above mentioned behaviors also show high levels of intention to carry out them. There is the hypothesis that besides cognitive variables such as attitudes, subjective norms, perceived behavioral control and intention, the personality of the young persons is an aspect that plays an important paper in their sexual and reproductive health. Significant correlations were found between the variales of the TPB and the personality traits; the results suggest that the direction of these correlations is associated with the specific type of behavior or situation that is assessed. Keywords: personality, theory of planned behavior, adolescents, reproductive sexuality.

Growing up in Affiliation with a Religious Community : A Case Study of Seventh-day Adventist Youth in Finland

This study investigates how the religious community as a socialization context affects the development of young people's religious identity and values, using Finnish Seventh-day Adventism as a context for the case study. The research problem is investigated through the following questions: (1) What aspects support the intergenerational transmission of values and tradition in religious home education? (2) What is the role of social capital and the social networks of the religious community in the religious socialization process? (3) How does the religious composition of the peer group at school (e.g., a denominational school in comparison to a mainstream school) affect these young people s social relations and choices and their religious identity (as challenged versus as reinforced by values at school)? And (4) How do the young people studied negotiate their religious values and religious membership in the diverse social contexts of the society at large? The mixed method study includes both quantitative and qualitative data sets (3 surveys: n=106 young adults, n=100 teenagers, n=55 parents; 2 sets of interviews: n=10 young adults and n=10 teenagers; and fieldwork data from youth summer camps). The results indicate that, in religious home education, the relationship between parents and children, the parental example of a personally meaningful way of life, and encouraging critical thinking in order for young people to make personalized value choices were important factors in socialization. Overall, positive experiences of the religion and the religious community were crucial in providing direction for later choices of values and affiliations. Education that was experienced as either too severe or too permissive was not regarded as a positive influence for accepting similar values and lifestyle choices to those of the parents. Furthermore, the religious community had an important influence on these young people s religious socialization in terms of the commitment to denominational values and lifestyle and in providing them with religious identity and rooting them in the social network of the denomination. The network of the religious community generated important social resources, or social capital, for both the youth and their families, involving both tangible and intangible benefits, and bridging and bonding effects. However, the study also illustrates the sometimes difficult negotiations the youth face in navigating between differentiation and belonging when there is a tension between the values of a minority group and the larger society, and one wants to and does belong to both. It also demonstrates the variety within both the majority and the minority communities in society, as well as the many different ways one can find a personally meaningful way of being an Adventist. In the light of the previous literature about socialization-in-context in an increasingly pluralistic society, the findings were examined at four levels: individual, family, community and societal. These were seen as both a nested structure and as constructing a funnel in which each broader level directs the influences that reach the narrower ones. The societal setting directs the position and operation of religious communities, families and individuals, and the influences that reach the developing children and young people are in many ways directed by societal, communal and family characteristics. These levels are by nature constantly changing, as well as being constructed of different parts, like the pieces of a jigsaw puzzle, each of which alters in significance: for some negotiations on values and memberships the parental influence may be greater, whereas for others the peer group influences are. Although agency does remain somewhat connected to others, the growing youth are gradually able to take more responsibility for their own choices and their agency plays a crucial role in the process of choosing values and group memberships. Keywords: youth, community, Adventism, socialization, values, identity negotiations

Adhesion-Induced Instability in Asperities

Adhesive forces between two approaching asperities will deform the asperities, and under certain conditions this will result in a sudden runaway deformations leading to a jump-to-contact instability. We present finite element-based numerical studies on adhesion-induced deformation and instability in asperities. We consider the adhesive force acting on an asperity, when it is brought near a rigid half-space, due to van der Waals interaction between the asperity and the half-space. The adhesive force is considered to be distributed over the volume of the asperity (body force), thus resulting in more realistic simulations for the length scales considered. Iteration scheme based on a ``residual stress update'' algorithm is used to capture the effect of deformation on the adhesion force, and thereby the equilibrium configuration and the corresponding force. The numerical results are compared with the previous approximate analytical solutions for adhesion force, deformation of the asperity and adhesion-induced mechanical instability (jump-to-contact). It is observed that the instability can occur at separations much higher,and could possibly explain the higher value of instability separation observed in experiments. The stresses in asperities, particularly in case of small ones, are found to be high enough to cause yielding before jump -to-contact. The effect of roughness is considered by modeling a spherical protrusion on the hemispherical asperity.This small-scale roughness at the tip of the asperities is found to control the deformation behavior at small separations, and hence are important in determining the friction and wear due to the jump-to-contact instability.

Constructing a Community : Myths and Realities of the Open Development Model

The open development model of software production has been characterized as the future model of knowledge production and distributed work. Open development model refers to publicly available source code ensured by an open source license, and the extensive and varied distributed participation of volunteers enabled by the Internet. Contemporary spokesmen of open source communities and academics view open source development as a new form of volunteer work activity characterized by hacker ethic and bazaar governance . The development of the Linux operating system is perhaps the best know example of such an open source project. It started as an effort by a user-developer and grew quickly into a large project with hundreds of user-developer as contributors. However, in hybrids , in which firms participate in open source projects oriented towards end-users, it seems that most users do not write code. The OpenOffice.org project, initiated by Sun Microsystems, in this study represents such a project. In addition, the Finnish public sector ICT decision-making concerning open source use is studied. The purpose is to explore the assumptions, theories and myths related to the open development model by analysing the discursive construction of the OpenOffice.org community: its developers, users and management. The qualitative study aims at shedding light on the dynamics and challenges of community construction and maintenance, and related power relations in hybrid open source, by asking two main research questions: How is the structure and membership constellation of the community, specifically the relation between developers and users linguistically constructed in hybrid open development? What characterizes Internet-mediated virtual communities and how can they be defined? How do they differ from hierarchical forms of knowledge production on one hand and from traditional volunteer communities on the other? The study utilizes sociological, psychological and anthropological concepts of community for understanding the connection between the real and the imaginary in so-called virtual open source communities. Intermediary methodological and analytical concepts are borrowed from discourse and rhetorical theories. A discursive-rhetorical approach is offered as a methodological toolkit for studying texts and writing in Internet communities. The empirical chapters approach the problem of community and its membership from four complementary points of views. The data comprises mailing list discussion, personal interviews, web page writings, email exchanges, field notes and other historical documents. The four viewpoints are: 1) the community as conceived by volunteers 2) the individual contributor s attachment to the project 3) public sector organizations as users of open source 4) the community as articulated by the community manager. I arrive at four conclusions concerning my empirical studies (1-4) and two general conclusions (5-6). 1) Sun Microsystems and OpenOffice.org Groupware volunteers failed in developing necessary and sufficient open code and open dialogue to ensure collaboration thus splitting the Groupware community into volunteers we and the firm them . 2) Instead of separating intrinsic and extrinsic motivations, I find that volunteers unique patterns of motivations are tied to changing objects and personal histories prior and during participation in the OpenOffice.org Lingucomponent project. Rather than seeing volunteers as a unified community, they can be better understood as independent entrepreneurs in search of a collaborative community . The boundaries between work and hobby are blurred and shifting, thus questioning the usefulness of the concept of volunteer . 3) The public sector ICT discourse portrays a dilemma and tension between the freedom to choose, use and develop one s desktop in the spirit of open source on one hand and the striving for better desktop control and maintenance by IT staff and user advocates, on the other. The link between the global OpenOffice.org community and the local end-user practices are weak and mediated by the problematic IT staff-(end)user relationship. 4) Authoring community can be seen as a new hybrid open source community-type of managerial practice. The ambiguous concept of community is a powerful strategic tool for orienting towards multiple real and imaginary audiences as evidenced in the global membership rhetoric. 5) The changing and contradictory discourses of this study show a change in the conceptual system and developer-user relationship of the open development model. This change is characterized as a movement from hacker ethic and bazaar governance to more professionally and strategically regulated community. 6) Community is simultaneously real and imagined, and can be characterized as a runaway community . Discursive-action can be seen as a specific type of online open source engagement. Hierarchies and structures are created through discursive acts. Key words: Open Source Software, open development model, community, motivation, discourse, rhetoric, developer, user, end-user

Modelling transport processes during microwave heating: A review

The review is concerned with models that analyze transport:processes that occur during microwave heating. Early models on microwave. heating used Lambert's law to describe the microwave power absorption. Over the last decade, models for transport processes have been developed with the microwave power derived from Maxwell's equations. Those models, primarily based on plane waves, have been used for analyzing microwave heating of solids, liquids, emulsions, microwave thawing and drying. The models illustrate phenomena such a resonances, hot spots, edge and runaway heating. The literature on microwave sintering, susceptor heating and microwave assisted synthesis is largely experimental in nature and only key issues are highlighted. To fully appreciate the models for microwave heating, a section on the theory of electromagnetic wave propagation is included, where expressions for the electric field in dielectric slabs and cylinders are presented.

Turbulence and cooling in galaxy cluster cores

We study the interplay between turbulent heating, mixing, and radiative cooling in an idealized model of cool cluster cores. Active galactic nuclei (AGN) jets are expected to drive turbulence and heat cluster cores. Cooling of the intracluster medium (ICM) and stirring by AGN jets are tightly coupled in a feedback loop. We impose the feedback loop by balancing radiative cooling with turbulent heating. In addition to heating the plasma, turbulence also mixes it, suppressing the formation of cold gas at small scales. In this regard, the effect of turbulence is analogous to thermal conduction. For uniform plasma in thermal balance (turbulent heating balancing radiative cooling), cold gas condenses only if the cooling time is shorter than the mixing time. This condition requires the turbulent kinetic energy to be a parts per thousand(3) the plasma internal energy; such high velocities in cool cores are ruled out by observations. The results with realistic magnetic fields and thermal conduction are qualitatively similar to the hydrodynamic simulations. Simulations where the runaway cooling of the cool core is prevented due to mixing with the hot ICM show cold gas even with subsonic turbulence, consistent with observations. Thus, turbulent mixing is the likely mechanism via which AGN jets heat cluster cores. The thermal instability growth rates observed in simulations with turbulence are consistent with the local thermal instability interpretation of cold gas in cluster cores.

The cold mode: a phenomenological model for the evolution of density perturbations in the intracluster medium

Cool cluster cores are in global thermal equilibrium but are locally thermally unstable. We study a non-linear phenomenological model for the evolution of density perturbations in the intracluster medium (ICM) due to local thermal instability and gravity. We have analysed and extended a model for the evolution of an overdense blob in the ICM. We find two regimes in which the overdense blobs can cool to thermally stable low temperatures. One for large t(cool)/t(ff) (t(cool) is the cooling time and t(ff) is the free-fall time), where a large initial overdensity is required for thermal runaway to occur; this is the regime which was previously analysed in detail. We discover a second regime for t(cool)/t(ff) less than or similar to 1 (in agreement with Cartesian simulations of local thermal instability in an external gravitational field), where runaway cooling happens for arbitrarily small amplitudes. Numerical simulations have shown that cold gas condenses out more easily in a spherical geometry. We extend the analysis to include geometrical compression in weakly stratified atmospheres such as the ICM. With a single parameter, analogous to the mixing length, we are able to reproduce the results from numerical simulations; namely, small density perturbations lead to the condensation of extended cold filaments only if t(cool)/t(ff) less than or similar to 10.

La enseñanza de la bioética personalista promueve cambios en las actitudes de los alumnos adolescentes de la escuela pública

En este artículo se relata una experiencia de la enseñanza de la Bioética personalista aplicada a estudiantes de segundo año del nivel secundario de dos escuelas públicas ubicadas en una ciudad del interior de Río Grande do Sul, Brasil. Con el objetivo de evaluar la receptividad de la Bioética personalista se aplicó un cuestionario antes y después de dar charlas a un total de 194 alumnos de ambos sexos, entre 15 y 17 años. Se realizó un análisis estadístico comparativo de los resultados. Se evidenció la coincidencia de los alumnos en el pensar ontológico personalista, salvo en el área de la dignidad humana y la sexualidad. Los mejores resultados se obtuvieron en la escuela donde los profesores acompañaron el proceso. Se constató la necesidad de incentivar la capacidad crítica de los jóvenes para que aprendan a discernir los mecanismos de manipulación e imposición de determinadas ideologías. En este sentido, la formación de los educadores resultó ser muy necesaria y urgente para que los alumnos obtengan apoyo efectivo.

Assisting blog publication: annotation, model transformation, and crossblogging techniques

Although blogs exist from the beginning of the Internet, their use has considerablybeen increased in the last decade. Nowadays, they are ready for being used bya broad range of people. From teenagers to multinationals, everyone can have aglobal communication space.Companies know blogs are a valuable publicity tool to share information withthe participants, and the importance of creating consumer communities aroundthem: participants come together to exchange ideas, review and recommend newproducts, and even support each other. Also, companies can use blogs for differentpurposes, such as a content management system to manage the content of websites,a bulletin board to support communication and document sharing in teams,an instrument in marketing to communicate with Internet users, or a KnowledgeManagement Tool. However, an increasing number of blog content do not findtheir source in the personal experiences of the writer. Thus, the information cancurrently be kept in the user¿s desktop documents, in the companies¿ catalogues,or in another blogs. Although the gap between blog and data source can be manuallytraversed in a manual coding, this is a cumbersome task that defeats the blog¿seasiness principle. Moreover, depending on the quantity of information and itscharacterisation (i.e., structured content, unstructured content, etc.), an automaticapproach can be more effective.Based on these observations, the aim of this dissertation is to assist blog publicationthrough annotation, model transformation and crossblogging techniques.These techniques have been implemented to give rise to Blogouse, Catablog, andBlogUnion. These tools strive to improve the publication process considering theaforementioned data sources.

Perspectiva social de la infancia en algunas comunidades del País Vasco: Opiniones de las y los adolescentes de Santurtzi sobre sexismo

Resumen: El presente estudio ha intentado conocer la perspectiva que tienen las y los adolescentes de Santurtzi sobre el sexismo, eligiendo la adolescencia por su carácter fundamental en el desarrollo vital. Partimos de una investigación cualitativa llevada a cabo con 17 adolescentes a través de grupos de discusión sobre sexismo, patriarcado y alternativas de construcción personal, como son el movimiento feminista y el movimiento de nuevas masculinidades. Hemos podido corroborar el desconocimiento que todavía existe en materia de igualdad y la necesidad de intervenciones socioeducativas que de ello se desprenden, para así continuar con la lucha contra el patriarcado y contra la discriminación hacia la mujer, desde la perspectiva que nos aporta el sexismo ambivalente.

As formas de transmissão do HIV/AIDS determinando representações: um estudo de enfermagem entre adolescentes soropositivo

Este estudo objetivou analisar e comparar a incorporação psicossocial do HIV/AIDS entre adolescentes soropositivos considerando os diferentes meios de transmissão: vertical e sexual. Trata-se de um estudo de natureza descritiva, com abordagem qualitativa, fundamentado na teoria das representações sociais, na perspectiva da Psicologia Social. Foram estudados 30 adolescentes soropositivos atendidos em um Hospital Universitário do Rio de Janeiro. Foi utilizada como técnica de coleta de dados entrevistas semi-estruturadas e dois instrumentos de coleta: um questionário de caracterização dos sujeitos e um roteiro temático que guiou as entrevistas. As entrevistas foram gravadas e os conteúdos transcritos e analisados conforme a técnica de análise de conteúdo temática. O resultado evidenciou que o significado do HIV/AIDS para os sujeitos, numa análise geral, é marcado predominantemente por sentimentos negativos como medo e sofrimento. Imagens comuns aos dois grupos foram da morte e destruição, assim como o preconceito foi um importante conteúdo representacional. Ao comparar os dois grupos percebe-se que os elementos mais presentes na representação de adolescentes contaminados por relação sexual são sofrimento e o medo, com uma dimensão imagética associada à morte. O uso do preservativo também é outro conteúdo representacional marcante nos discursos deste grupo. A sexualidade está incorporada na representação relacionada às dificuldades com a mesma pós descoberta do vírus. Já os adolescentes contaminados por transmissão vertical tiveram como elementos mais presentes a aceitação e conformação da doença. O tratamento torna-se um importante conteúdo da representação para este grupo, relacionando-o ao cuidado à saúde e a imunodeficiência. Conclui-se, então, que a escolha do estudo das representações sociais e das técnicas de análise utilizadas foram pertinentes, pois permitiram identificar os principais elementos constituintes da representação social do HIV/AIDS, comparando as diferenças representacionais nos dois grupos de adolescentes estudados. Estes resultados servirão para reflexão crítica de profissionais de saúde , tanto na contribuição para repensar estratégias de educação em saúde para prevenção de DST/AIDS, quanto no posicionamento diante de adolescentes soropositivos.

BLOG: da Internet à sala de aula

Os diários de escrita íntima constituem tipo de texto do domínio confessional. Apresentam narrativas pessoais com características específicas ao gênero, como datação, marcas de subjetividade, escrita informal e coloquialidade. Durante muitos anos, eram escritos em cadernos e guardados a sete chaves por seus autores para que não fossem lidos por outras pessoas. Por volta dos anos 80, surgiram as agendas de adolescentes. Aproveitando o modelo pré-definido industrialmente, as agendas eram preenchidas dia a dia, como um diário, mas com a novidade do acréscimo de elementos semióticos, como fotos, papéis de bala, recortes de revistas, entre outros. Além disso, traziam como diferencial a presença de um leitor participativo: os textos eram compartilhados com amigos, e bilhetes e comentários eram escritos nas páginas das agendas. Com o advento da Internet, o diário e a agenda se fundem no blog que aproveita os recursos do suporte virtual para tornar o gênero interativo, hipertextual e multimídia, acentuando o processo de leitura e de escrita nos jovens produtores de blogs. Paralelamente, a escrita se torna grande ferramenta de comunicação no ambiente virtual, adquirindo características peculiares em função da rapidez na comunicação e da economia de digitação. A partir da teoria de Bakthin sobre gêneros do discurso e do conceito de gêneros digitais de Marcuschi, a pesquisa apresenta como objeto perceber e elencar categorias pertinentes aos gêneros diário e blog para analisá-las e compará-las, na intenção de mapear um possível percurso dos diários aos blogs de adolescentes, discutindo o contraste público-privado na escrita íntima, bem como suas principais marcas linguísticas, percebendo vantagens e desvantagens de sua utilização como ferramenta auxiliar no processo de aprendizagem da escrita e da leitura de Língua Portuguesa. A pesquisa foi motivada pela discussão de que a escrita digital pode prejudicar o desenvolvimento da produção textual de jovens em formação, o que não se confirmou, visto que a estrutura sintática da língua se mantém, e que a variação acontece apenas no nível vocabular, não interferindo na comunicação. Os resultados apontam para a utilização de blogs na educação como complementação do material pedagógico e como incentivo à leitura, à escrita, à construção da argumentação e do posicionamento crítico, aproximando a escola da vida cotidiana dos estudantes
