Lives apart? Experiences of transnational motherhood by Georgian labour migrants to Italy and their children

International labour migration processes of the last decades saw increasing numbers of solo female migrants employed in the developed countries. Many of these women were mothers who left their children in the sending countries and thus gave rise to a controversial phenomenon of transnational motherhood. The present thesis is based on the first empirical study of intergenerational narratives of mothers, Georgian labour migrants to Italy, and their children, left behind in Georgia. Mothers’ international labour migration is a challenge to the traditional ideology of motherhood. Although unconsciously migrant mothers often adhere to “alternative”, “rational”, future-oriented model(s) of parenting, they continue to live their experiences in the framework of traditional understandings of motherhood, which appears to be unequipped to “frame” transnational motherhood as, from its point of view, mothers’ choice to leave their children is reprehensible, yet transnational mothers’ physical absence is not an equivalent of “leaving” their children. Informants’ narratives strongly suggest that long periods of physical separation did not jeopardize bonds between mothers and children in transnational families. While informants’ selection bias is probable, the mother-child bond was not “broken” and the very essence of motherhood remained intact. Many forms of mothers’ and children’s online co-presence were documented during the interviews. Interviews also prove that the Internet cannot be considered a solution to the problem of family separation, experienced painfully by both mothers and children: it may reduce the pain caused by separation, but cannot be a substitute for mothers’ physical absence from their families. Despite the pain caused by separation, mothers’ emigration appeared to be the right decision made for the good of the family. Interviewed mothers almost univocally reported readiness to “keep going on”, and continue working in emigration to help their children until physically able to do so, because, as they put it, “motherhood never ends”.

The martensitic transformation in ceramics - its role in transformation toughening

This paper reviews the current knowledge and understanding of martensitic transformations in ceramics - the tetragonal to monoclinic transformation in zirconia in particular. This martensitic transformation is the key to transformation toughening in zirconia ceramics. A very considerable body of experimental data on the characteristics of this transformation is now available. In addition, theoretical predictions can be made using the phenomenological theory of martensitic transformations. As the paper will illustrate, the phenomenological theory is capable of explaining all the reported microstructural and crystallographic features of the transformation in zirconia and in some other ceramic systems. Hence the theory, supported by experiment, can be used with considerable confidence to provide the quantitative data that is essential for developing a credible, comprehensive understanding of the transformation toughening process. A critical feature in transformation toughening is the shape strain that accompanies the transformation. This shape strain, or nucleation strain, determines whether or not the stress-induced martensitic transformation can occur at the tip of a potentially dangerous crack. If transformation does take place, then it is the net transformation strain left behind in the transformed region that provides toughening by hindering crack growth. The fracture mechanics based models for transformation toughening, therefore, depend on having a full understanding of the characteristics of the martensitic transformation and, in particular, on being able to specify both these strains. A review of the development of the models for transformation toughening shows that their refinement and improvement over the last couple of decades has been largely a result of the inclusion of more of the characteristics of the stress-induced martensitic transformation. The paper advances an improved model for the stress-induced martensitic transformation and the strains resulting from the transformation. This model, which separates the nucleation strain from the subsequent net transformation strain, is shown to be superior to any of the constitutive models currently available.

Influência e contrainfluência na inversão do poder tipográfico entre Portugal e o Brasil: narrativa e atividade nos editores portugueses

Tempo fértil em alterações que transformaram a face do universo editorial em Portugal e no Brasil, os anos que decorrem entre a última metade da década de 1930 e o fim da década de 1960 constituem o período em que se assiste a uma inversão nos processos de influência tipográfica entre os dois países, com Portugal a passar de exportador para importador de livros no seu comércio com o Brasil. Este artigo pretende analisar o ponto de vista da edição portuguesa nos modos variados como os seus agentes foram representando o Brasil enquanto centro produtor e disseminador do livro, e como as mudanças suscitadas foram ocorrendo num contexto de oscilação – e tensão – entre discursos amarrados a uma época de ouro (ou imaginada como tal) que ficava relutantemente para trás e práticas de colaboração efectiva entre os universos tipográficos português e brasileiro, essencialmente suportadas na actuação de editores individuais. ABSTRACT - There was a time of many alterations that changed the face of the publishing world in Portugal and Brazil during the years spanning from the second half of the 1930’s to the end of the 1960’s. This was a period in which one could observe an inversion of publishing influences between the two countries, with Portugal shifting its role and becoming a net book importer in its trade with Brazil. This article intends to analyze the Portuguese publishing world’s point of view as their agents in different ways changed their attitudes toward Brazil as a centre of book production and diffusion. The text also sets out to understand how these transformations occurred in a context of oscillation – and tension – among discourses tied to a golden age (or imagined as such) that was reluctantly left behind, and practices of effective collaboration between the Portuguese and Brazilian publishing worlds – resulting fundamentally from the actions of individual publishers.

Comportamento do Heterocromossômio em alguns Ortópteros do Brasil

In the present paper the behavior of the heterochromoso-mes in the course of the meiotic divisions of the spermatocytes in 15 species of Orthoptera belonging to 6 different families was studied. The species treated and their respective chromosome numbers were: Phaneropteridae: Anaulacomera sp. - 1 - 2n = 30 + X, n +15+ X and 15. Anaulacomera sp. - 2 - 2n - 30 + X, n = 15+ X and 15. Stilpnochlora marginella - 2n = 30 + X, n = 15= X and 15. Scudderia sp. - 2n = 30 + X, n = 15+ X and 15. Posldippus citrifolius - 2n = 24 + X, n = 12+X and 12. Acrididae: Osmilia violacea - 2n = 22+X, n = 11 + X and 11. Tropinotus discoideus - 2n = 22+ X, n = 11 + X and 11. Leptysma dorsalis - 2n = 22 + X, n = 11-J-X and 11. Orphulella punctata - 2n = 22-f X, n = 11 + X and 11. Conocephalidae: Conocephalus sp. - 2n = 32 + X, n = 16 + X and 16. Proscopiidae: Cephalocoema zilkari - 2n = 16 + X, n = 8+ X and 8. Tetanorhynchus mendesi - 2n = 16 + X, n = 8+X and 8. Gryliidae: Gryllus assimilis - 2n = 28 + X, n = 14+X and 14. Gryllodes sp. - 2n = 20 + X, n = 10- + and 10. Phalangopsitidae: Endecous cavernicola - 2n = 18 +X, n = 94-X and 9. It was pointed out by the present writer that in the Orthoptera similarly to what he observed in the Hemiptera the heterochromosome in the heterocinetic division shows in the same individual indifferently precession, synchronism or succession. This lack of specificity is therefore pointed here as constituting the rule and not the exception as formerly beleaved by the students of this problem, since it occurs in all the species referred to in the present paper and probably also m those hitherto investigated. The variability in the behavior of the heterochromosome which can have any position with regard to the autosomes even in the same follicle is attributed to the fact that being rather a stationary body it retains in anaphase the place it had in metaphase. When this place is in the equator of the cell the heterochromosome will be left behind as soon as anaphase begins (succession). When, on the contrary, laying out of this plane as generally happens (precession) it will sooner be reached (synchronism) or passed by the autosomes (succession). Due to the less kinetic activity of the heterochromosome it does not orient itself at metaphase remaining where it stands with the kinetochore looking indifferently to any direction. At the end of anaphase and sometimes earlier the heterochromosome begins to show mitotic activities revealed by the division of its body. Then, responding to the influence of the nearer pole it moves to it being enclosed with the autosomes in the nucleus formed there. The position of the heterochromosome in the cell is explained in the following manner: It is well known that the heterochromosome of the Orthoptera is always at the periphery of the nucleus, just beneath the nuclear membrane. This position may be any in regard of the axis of the dividing cell, so that if one of the poles of the spindle comes to coincide with it, the heterochromosome will appear at this pole in the metaphasic figures. If, on the other hand, the angle formed by the axis of the spindle with the ray reaching the heterochromosome increases the latter will appear in planes farther and farther apart from the nearer pole until it finishes by being in the equatorial plane. In this way it is not difficult to understand precession, synchronism or succession. In the species in which the heterochromosome is very large as it generally happens in the Phaneropteridae, the positions corresponding to precession are much more frequent. This is due to the fact that the probabilities for the heterochromosome taking an intermediary position between the equator and the poles at the time the spindle is set up are much greater than otherwise. Moreover, standing always outside the spindle area it searches for a place exactly where this area is larger, that is, in the vicinity of the poles. If it comes to enter the spindle area, what has very little probability, it would be, in virtue of its size, propelled toward the pole by the nearing anaphasic plate. The cases of succession are justly those in which the heterochromosome taking a position parallelly to the spindle axis it can adjust its large body also in the equator or in its proximity. In the species provided with small heterochromosome (Gryllidae, Conocephalidae, Acrididae) succession is found much more frequently because here as in the Hemiptera (PIZA 1945) the heterochromosome can equally take equatorial or subequatorial positions, and, furthermore, when in the spindle area it does offer no sereous obstacle to the passage of the autosomes. The position of the heterochromosome at the periphery of the nucleus at different stages may be as I suppose, at least in part a question of density. The less colourability and the surface irregularities characteristic of this element may well correspond to a less degree of condensation which may influence passive movements. In one of the species studied here (Anaulacomera sp.- 1) included in the Phaneropteridae it was observed that the plasmosome is left motionless in the spindle as the autosomes move toward the poles. It passes to one of the secondary spermatocytes being not included in its nucleus. In the second division it again passes to one of the cells being cast off when the spermatid is being transformed into spermatozoon. Thus it is regularly found among the tails of the spermatozoa in different stages of development. In the opinion of the present writer, at least in some cases, corpuscles described as Golgi body's remanents are nothing more than discarded plasmosomes.

Large fluctuations in the disassembly rate of microtubules revealed by atomic force microscopy.

Atomic force microscopy (AFM) in situ has been used to observe the cold disassembly dynamics of microtubules at a previously unrealised spatial resolution. Microtubules either electrostatically or covalently bound to aminosilane surfaces disassembled at room temperature under buffer solutions with no free tubulin present. This process was followed by taking sequential tapping-mode AFM images and measuring the change in the microtubule end position as a function of time, with an spatial accuracy down to +/-20nm and a temporal accuracy of +/-1s. As well as giving average disassembly rates on the order of 1-10 tubulin monomers per second, large fluctuations in the disassembly rate were revealed, indicating that the process is far from smooth and linear under these experimental conditions. The surface bound rates measured here are comparable to the rates for GMPCPP-tubulin microtubules free in solution, suggesting that inhibition of tubulin curvature through steric hindrance controls the average, relatively low disassembly rate. The large fluctuations in this rate are thought to be due to multiple pathways in the kinetics of disassembly with differing rate constants and/or stalling due to defects in the microtubule lattice. Microtubules that were covalently bound to the surface left behind the protofilaments covalently cross-linked to the aminosilane via glutaraldehyde during the disassembly process. Further work is needed to quantitatively assess the effects of surface binding on protofibril disassembly rates, reveal any differences in disassembly rates between the plus and minus ends and to enable assembly as well as disassembly to be imaged in the microscope fluid cell in real-time.

Energy relaxation in nonlinear one-dimensional lattices

We study energy relaxation in thermalized one-dimensional nonlinear arrays of the Fermi-Pasta-Ulam type. The ends of the thermalized systems are placed in contact with a zero-temperature reservoir via damping forces. Harmonic arrays relax by sequential phonon decay into the cold reservoir, the lower-frequency modes relaxing first. The relaxation pathway for purely anharmonic arrays involves the degradation of higher-energy nonlinear modes into lower-energy ones. The lowest-energy modes are absorbed by the cold reservoir, but a small amount of energy is persistently left behind in the array in the form of almost stationary low-frequency localized modes. Arrays with interactions that contain both a harmonic and an anharmonic contribution exhibit behavior that involves the interplay of phonon modes and breather modes. At long times relaxation is extremely slow due to the spontaneous appearance and persistence of energetic high-frequency stationary breathers. Breather behavior is further ascertained by explicitly injecting a localized excitation into the thermalized arrays and observing the relaxation behavior.

Exploring the relative DNA contribution of first and second object's users on mock touch DNA mixtures

Contact stains recovered at break-in crime scenes are frequently characterized by mixtures of DNA from several persons. Broad knowledge on the relative contribution of DNA left behind by different users overtime is of paramount importance. Such information might help crime investigators to robustly evaluate the possibility of detecting a specific (or known) individual's DNA profile based on the type and history of an object. To address this issue, a contact stain simulation-based protocol was designed. Fourteen volunteers either acting as first or second object's users were recruited. The first user was required to regularly handle/wear 9 different items during an 8-10-day period, whilst the second user for 5, 30 and 120 min, in three independent simulation sessions producing a total of 231 stains. Subsequently, the relative DNA profile contribution of each individual pair was investigated. Preliminary results showed a progressive increase of the percentage contribution of the second user compared to the first. Interestingly, the second user generally became the major DNA contributor when most objects were handled/worn for 120 min, Furthermore, the observation of unexpected additional alleles will then prompt the investigation of indirect DNA transfer events.

Elders and the ITCs use to communicate with children and grandchildren

Past research in using ICTs (Information and Communication Technologies) in interpersonal communication showed that age plays an important role. There is a general assumption that the elderly are left behind regarding the adoption and the use of ICTs. Furthermore, elders tend to use ICTs mainly for instrumental purposes and the use is rather non-sophisticated. When elders are using ICTs to maintain their social network, similar patterns could be found: They start using internet, or intensify its use, when their children move abroad while they might decrease using the tool if the motivation ends. In this research we explore elders' incentives to go online and use internet services to communicate; the type of agencies they use to communicate with children and grandchildren abroad; and the situations that make them stop using the ICTs or even reject internet mediated communications. We base our discussion on the empirical evidence the two authors gathered in different cities and countries: Barcelona, Romania, Toronto, Los Angeles, Montevideo and Lima, through semi-structured interviews and observation, with people aged 60 years old and over. The results show that the ability for using ICT tools in an autonomous way is a better explanation than age. In this, we distinguish between assisted users and autonomous users. We found that oldest seniors and those seniors who are less socially active are more likely to be assisted users than those who are socially or professionally active. For them communication with their children and grandchildren abroad follows no agency or it is mediated by significant others from their local social network, who are able to use ICTs and select specific information to share, in the second step, with the elder. For some younger participants the use of ICTs is rather situational and imposed by their children or grandchildren, who installed the tool in the first place and assisted them in using it. Finally, other elders describe a proficient and independent use of ICTs so they use the devices and services the way they want to.We discuss the implications of the patterns in using ICTs, for elders' social life and their relationships with children and grandchildren. First, we emphasis the fact that those elders rejecting the ICTs or being unskilled in using them to communicate might be left out from their family circle, particularly when children are abroad -they would experience more isolation. Second, we underline the fact that when children and grandchildren are the ones that control the ICTs used by their parents and grandparents, they are controlling also the information flow and this will redefine the power relations between elders and their younger relatives.

Breaking the silence : exploring the workplace experiences of six women with learning disabilities

In the current economic climate, employees are expected to upgrade their skills in order to remain productive and competitive in the workplace, and many women with learning disabilities! may feel doubly challenged when dealing with such expectations. Although the number of people with reported learning disabilities who enter the workforce is expected to increase, a dearth of research focuses on work-related experiences of women with learning disabilities; consequently, employers and educators often are unaware ofthe obstacles and demands facing such individuals. This qualitative narrative study sheds light on the work experiences of women with diagnosed or suspected learning disabilities. The study used semistructured interviews to explore their perspectives and reflections on learnlng in order to: (a) raise awareness of the needs of women with learning disabilities, (b) enhance their opportunities to learn in the workplace, and (c) draw attention to the need for improvement of inclusiveness in the workplace, especially for hidden disabilities. Study findings reveal that participants' learning was influenced by work relationships, the learning environments, self-determination, and taking personal responsibility. Moreover, the main accommodation requested was to have supportive and understanding work relationships and environments. Recommendations are made for future research and workplace improvements, most notably that no employees should be left behind through an employee-centered approach.

Woodruff Family fonds, 1784 – 1983, (non-inclusive)

The Woodruff Family Collection: From the time the Woodruff Family came to Canada from the United States in 1795, they took an active role in the forming of their communities both in a civic and social manner. This is evident through the documents contained in this collection. The Woodruffs played an active role in the battles fought in Upper Canada and they were an integral part of the Village of St. Davids. They were educated, business-minded and socially engaged. They accumulated much of their fortune through land dealings. Much of this collection focuses on Samuel DeVeaux Woodruff who was principally a businessman. His dedication to his work is shown through his numerous undertakings. He made his mark on the Niagara Peninsula through his work on the railways, roads, marsh land revisions, canals and the paper industry. He was also involved with the founding of the Long Point Company and he took control of building DeVeaux Hall down to the last detail. His offspring inherited his work ethic and his business acumen. The people who married into the Woodruff Family also possessed key social, political and business ties. Anne and Margaret Clement were from a staunch Loyalist background. Samuel Zimmerman was instrumental to the founding of Niagara Falls and Judge Samuel DeVeaux left behind a legacy for poor and homeless boys in Niagara Falls, New York. The Woodruff Family undoubtedly left a mark on the Niagara Peninsula. This collection brings to light many endeavours of the family and their varied contributions.

L'herméneutique dans l'oeuvre d'Emmanuel Levinas

Ce mémoire est consacré au problème de la place de l’herméneutique dans l’œuvre d’Emmanuel Levinas. Au premier abord, l’œuvre semble présenter une forte ambivalence quant à la valeur que le philosophe accorde aux catégories herméneutiques. D’abord, dans les œuvres proprement philosophiques, Levinas présente une critique sévère de la compréhension dans laquelle il décèle un geste de totalisation et d’appropriation du sens contre lequel il élèvera une pensée de l’éthique comme « philosophie première ». D’autre part, un autre pan du corpus levinassien, celui des Lectures talmudiques, est consacré au déploiement d’une herméneutique des textes religieux de la tradition juive où Levinas fait puissamment intervenir les catégories éthiques propres à sa philosophie au sein de son activité exégétique. L’un des paradoxes intéressants que nous présente donc l’œuvre levinassienne est celui d’une philosophie s’érigeant en bonne partie sur une critique de la catégorie centrale de l’herméneutique, la compréhension, et qui ne se décline pas moins elle-même en une théorie de l’interprétation des textes. Afin de résoudre ce paradoxe, il nous faut d’abord exposer la critique de la compréhension qui est consubstantielle au projet philosophique de Levinas. En nous appuyant sur quelques textes centraux de son œuvre, nous expliciterons à la fois le déficit éthique de la compréhension que pointe Levinas et les possibilités de sens au nom desquelles cette critique s’accomplit. Nous verrons ainsi ce qui conduit Levinas à suggérer qu’autrui, en son visage, témoigne d’un sens qui ferait exception à la structure gnoséologique du sensé que suppose l’herméneutique. Dans un deuxième temps, nous tenterons de cerner les raisons qui peuvent légitiment conduire Levinas à faire usage, dans le contexte de son herméneutique talmudique, des « concepts » nés de sa critique de la compréhension. L’étude du rapport entre éthique et herméneutique, entre texte et visage, nous conduira à identifier le principe directeur de l’herméneutique levinassienne et à articuler la façon dont il se rattache à l’éthique du visage. Finalement, nous tenterons de faire valoir la pertinence philosophique de l’herméneutique levinassienne en étudiant la manière dont elle peut rendre compte de phénomènes fondamentaux liés à l’interprétation des textes.
