The young infant's triangular communication in the family : access to threesome intersubjectivity ? Conceptual considerations and case illustrations

During these last decades, the notion of primary intersubjectivity has gained acceptance among developmentalists and clinicians. But a new challenge is put out to our models by recent findings on the triangular competence of the very young infant, or her capacity to simultaneously communicate with two partners at a time. This discovery raises the question of a collective form of intersubjectivity. Findings on the triangular competence of the 3- to 4-month-old interactions with father and mother in different contexts of the Lausanne trilogue play situation are reviewed and illustrated, with a view to examine whether it is based on a dyadic or triangular program and whether conditions for a threesome form of primary intersubjectivity are fulfilled. The discussion focuses on the revisions of the theory of intersubjectivity, of developmental theory, and of clinical practice these findings call for, pointing toward a three -person psychology too.

Simulação estocástica de atributos do clima e da produtividade potencial de milho utilizando-se distribuição triangular

O objetivo deste trabalho foi simular a produtividade potencial da cultura de milho, pelo método de Monte Carlo, utilizando um modelo agrometeorológico estocástico. O experimento foi conduzido em Piracicaba, SP, a 22º42'30''S, 47º38'30''W, e altitude de 546 m, o clima da região é do tipo Cwa (tropical úmido). Foram utilizados os valores médios diários de temperatura (de 1917 a 2002) e radiação solar global (de 1978 a 2002). Para comparar os dados reais com os simulados, foram utilizados índices de desempenho estatístico. Observou-se que os modelos probabilísticos, desenvolvidos para a simulação de dados médios diários de temperatura e de radiação solar global, geraram valores semelhantes aos observados por meio da distribuição triangular, a qual pode ser utilizada em modelo estocástico, para previsão da produtividade potencial de milho, nas diferentes épocas de semeadura.

Infant's triangular communication in "two for one" versus "two against one" family triangles: Case illustrations

Infants use their social competence very early to communicate not only in dyads but also in triads, in particular in the triangle they form with their mother and father. The development of this triangular communication is largely shaped by the ways the parents support or undermine each other in relation to their child. Whereas triangular communication is facilitated in "two for one" alliances, it is recruited in the service of regulating the parents' conflicts in "two against one" coalitions. These processes are manifest in toddlerhood and may be traced back to the coparenting alliance in formation during pregnancy.

The maximum voltage drop in an on-chip power distribution network: analysis of square, triangular and hexagonal power pad arrangements

A mathematical model of the voltage drop which arises in on-chip power distribution networks is used to compare the maximum voltage drop in the case of different geometric arrangements of the pads supplying power to the chip. These include the square or Manhattan power pad arrangement, which currently predominates, as well as equilateral triangular and hexagonal arrangements. In agreement with the findings in the literature and with physical and SPICE models, the equilateral triangular power pad arrangement is found to minimize the maximum voltage drop. This headline finding is a consequence of relatively simple formulas for the voltage drop, with explicit error bounds, which are established using complex analysis techniques, and elliptic functions in particular.

Spain, Economic Crisis, and the New Enclosure of the Reproductive Commons

In the past f ew years numerous authors have examined how the current economic crisis in Spain has dif f erential impacts on women and men.1 While this is important to show, this article’s goal is to make the leap f rom a mere description of the gendered effects of the crisis, to an analysis of some of the very gendered processes that shape it at its core. In other words, the intent is to understand how both the crisis itself and the ways the state manages it are structurally shaped by gender.

The octagon, the hendecagon and the approximation of pi: the geometric design of the clypeus in the enclosure of Imperial cult in Tarraco

The ancient temple dedicated to the Roman Emperor Augustus on the hilltop of Tarraco (today’s Tarragona), was the main element of the sacred precinct of the Imperial cult. It was a two hectare square, bordered by a portico with an attic decorated with a sequence of clypeus (i.e. monumental shields) made with marble plates from the Luni-Carrara’s quarries. This contribution presents the results of the analysis of a three-dimensional photogrammetric survey of one of these clipeus, partially restored and exhibited at the National Archaeological Museum of Tarragona. The perimeter ring was bounded by a sequence of meanders inscribed in a polygon of 11 sides, a hendecagon. Moreover, a closer geometric analysis suggests that the relationship between the outer meander rim and the oval pearl ring that delimited the divinity of Jupiter Ammon can be accurately determined by the diagonals of an octagon inscribed in the perimeter of the clypeus. This double evidence suggests a combined layout, in the same design, of an octagon and a hendecagon. Hypothetically, this could be achieved by combining the octagon with the approximation to Pi used in antiquity: 22/7 of the circle’s diameter. This method allows the drawing of a hendecagon with a clearly higher precision than with other ancient methods. Even the modelling of the motifs that separate the different decorative stripes corroborates the geometric scheme that we propose.

Relación triangular en danza movimiento terapia: "cuando el instante no es efímero"

Esta tesina pretende investigar si el concepto de relación triangular existe y es apto para el campo de la Danza Movimiento Terapia. Para lograr esto nos basaremos en una correlación teórica con el campo de la arte terapia, donde la relación triangular se utiliza como herramienta de trabajo terapéutico. Nuestro fin es encontrar resultados teórico/prácticos, que permitan visualizar su existencia y nos muestren lo que sucede en la relación terapéutica, cuando dicho término se consolida. En este camino, la materialización de la danza/movimiento, como tercer elemento de la relación triangular, será un punto clave e interesante, que nos mostrará nuevos caminos psicoterapéuticos.

Uniformidade de aplicação de água de equipamentos autopropelidos de irrigação com aspersores de perfil radial triangular, elíptico e retangular

Este trabalho apresenta resultados de simulações digitais da uniformidade de aplicação de água de sistemas autopropelidos de irrigação, para a condição de ausência de ventos. Nas simulações foram considerados aspersores com perfis radiais de distribuição de água tipo triangular, elíptico e retangular, operando sob diferentes combinações de ângulo de giro (de 180 até 360º) e espaçamento entre carreadores (de 0 a 100% do diâmetro molhado - DM). Os resultados das simulações foram apresentados em três grupos distintos, cada um representando a mesma forma geométrica do perfil radial de distribuição de água. Independentemente do ângulo de giro, os melhores valores de uniformidade foram obtidos com espaçamentos menores que 45% e entre 55% e 70% do DM para o perfil radial triangular e com espaçamentos menores que 50% e entre 70% e 90% do DM para os perfis radiais elíptico e retangular. Para os três perfis radiais, ângulos de giro do aspersor entre 180 e 230º geram maiores valores de coeficiente de uniformidade.

The improvement of enclosure protection class of power electronics device

Tässä diplomityössä tutkittiin vaihtoehtoja tehoelektroniikkalaitteiden kotelointiluokan kehittämiseksi. Haasteena paremman suojauksen suunnittelussa on laitteiden tuottama suuri määrä lämpöä, joka vaatii tehokkaan jäähdytyksen. Työn tuloksena saatu prototyyppi IP33 luokkaa varten täyttää standardissa SFS-EN 60529+A1 asetetut vaatimukset kyseiselle kotelointiluokalle. Rakenteessa ja valmistettavuudessa havaittiin muutama ongelma, jotka ovat korjattavissa pienillä muutoksilla. Korkeampia suojausluokkia varten testattiin IP54-luokiteltujen filtterituulettimien vaikutusta laitteen jäähdytykseen. Testien perusteella jäähdytysteho on riittävä ja filtterituulettimet todettiin toimivaksi ratkaisuksi korkeammille suojausluokille. Työn perusteella voidaan todeta, että nykyiset laitteet voidaan muokata vastaamaan IP33 luokan vaatimuksia kohtuullisen pienillä muutoksilla. Tätä korkeammat suojausluokat vaatisivat niin suuria muutoksia designiin, että todennäköisesti täysin uuden laitteen suunnittelu olis kannattavin vaihtoehto.

Excitation of low-profile equilateral-triangular dielectric resonator antenna using a conducting conformal strip

A new configuration that employs a conducting conformal strip to excite the low-profile equilaterial-triangular dielectric resonator antenna (DRA) of very high permittivity is proposed. As compared with the previous aperture-coupling configuration, the new configuration has a wider impedance bandwidth (- 5.5%) and a higher front-to-back radiation ratio. The return loss, radiation patterns, and antenna gain are measured and discussed

Compact dual-polarised square microstrip antenna with triangular slots for wireless communication

Design of a dual linearly-polarised microstrip patch antenna, excited by two orthogonal microstrip feed lines, is presented. A reduction in patch size of 35% is obtained when compared to a square patch operating at the same frequency. The polarisations are oriented at +45 and - 45 with an isolation of more than 36 dB between the ports. Unlike earlier designs, the proposed structure provides better gain.

Attitudes and behaviour towards food attributes and organic food – a triangular methodological investigation of occasional organic consumers

Organic food is increasingly available in the conventional food retail, where organic products are offered alongside with various other types of products and compete mainly with conventional and the so-called conventional-plus products. The latter are conventional products displaying particular quality attributes on the product packaging, such as ‘no artificial additives’, or ‘from animal welfare husbandry’. Often, these quality attributes also apply to organic products. Occasional organic consumers might prefer such conventional-plus alternatives that are perceived to be ‘between’ organic and conventional products. The overall objective of this PhD thesis was to provide information about the segment of occasional organic consumers. In particular, the thesis focussed on consumer perceptions and attitudes towards the quality of, and preferences for, organic, conventional and conventional-plus products in two countries: Germany and Switzerland. To achieve these objectives, qualitative and quantitative consumer research was combined in order to explore occasional organic consumers’ perceptions and attitudes as well as to observe their preferences and buying behaviour regarding different types of food products: organic, conventional and conventional-plus products. The qualitative research showed that, depending on single criteria, organic production was both positively as well as negatively assessed by consumers. Consumer perception of organic food was found to be highly selective and primarily focussed on the final stage of the particular production process. A major problem is that consumers are still mostly unfamiliar with factors associated with organic production, have a lack of confidence, and often confuse organic with conventional products. Besides this, consumer expectations of organic products are different from the expectations of conventional products. The quantitative research revealed that attitudes strongly determine consumers’ preferences for organic, conventional and conventional-plus products. Consumer attitudes tended to differ more between organic and conventional choices rather than conventional-plus and conventional choices. Furthermore, occasional organic consumers are heterogeneous in their preferences. They can be grouped into two segments: the consumers in one segment were less price sensitive and preferred organic products. The consumers in the other segment were more price sensitive and rather preferred conventional-plus or conventional products. To conclude, given the selective and subjective nature of consumer perception and the strong focus of consumer perception on the final stage of the food production process, specific additional values of organic farming should be communicated in clear and catchy messages. At the same time, these messages should be particularly focussed on the final stage of organic food production. The communication of specific added values in relation with organic products to improve the perceived price-performance-ratio is important since conventional-plus products represent an interesting alternative particularly for price sensitive occasional organic consumers. Besides this, it is important to strengthen affirmative consumer attitudes towards organic production. Therefore, policy support should emphasise on long-term communication campaigns and education programmes to increase the consumer awareness and knowledge of organic food and farming. Since consumers expect that organic food is regionally or at least domestically produced while they less accept organic imports, policy support of domestic and regional producers is a crucial measure to fill the current gap between the increasing consumer demand of organic food and the stagnation of the domestic and regional organic food supply.
