Extracurricular Science Labs for STEM Talent Support
No full textIn the past decade, a growing lack of engineers, natural scientists, information technology experts, and mathematicians has been noted, especially in Europe. Corresponding to the need to attract young people to science and technology, numerous extracurricular science labs
(“out-of-school labs”) have been established, especially in Germany. One of these initiatives is the DLR_School_Lab Oberpfaffenhofen, operated by Germany’s national research center for aeronautics and space, DLR, and a typical example of such an out-of-school lab. It offers hands-on experiments for secondary-school classes, advanced teacher training, and, as a special feature, enrichment courses for gifted students. In this article the concept behind the DLR_School_Lab is described, as well as the suitability of this lab to offer enrichment projects for talented school students. Other aspects discussed are its teacher education concept and the
effectiveness of the concept of extracurricular science labs

Chronic abdominal aortic dissection, endovascular treatment using a new Stent-graft for in situ Fenestration
No full textBackground: Although endovascular treatment of the thoracic aorta (TEVAR) has become an elective procedure for treatment of complicated type B aortic dissection, its role in treating post dissection thoraco-abdominal aortic aneurysm (TAAA), is still limited. This is a case of aortic vascular disease, which reports the use of a new endovascular device.
Case presentation: We present the case of a 62 year old male patient with a history of hypertension, active smoker, who presented penetrating descending thoracic aortic ulcer in the setting of a chronic abdominal aortic dissection. The patient was treated using a new stent graft capable of in situ fenestration that allowed crossing the stent-graft membrane, implanting a covered stent to exclude the re-entry at the level of the left renal artery and redirecting the blood flow through the true lumen.
Conclusions: This case report demonstrates the feasibility of a novel stent-graft concept. Larger studies with longer follow-up are essential to fully evaluate the safety and effectiveness of this new design.Fil: Bertoni, Hernán Gabriel. Fleni. Servicio de Cardiología.

Sri Lanka’s water policy: themes and issues
No full textFresh water resources in Sri Lanka remain a free public good with the State acting as the trustee and custodian of the resource. Although the country is blessed with a seemingly plentiful supply of water, it encounters severe problems of temporal and spatial scarcity. Nearly five decades of efforts at formulating a national water policy with a view to introducing a bulk water allocation system have failed mainly due to a lack of understanding of the basic issues confronting certain elements that constitute the basic policy. This paper presents selected key themes and issues which help stimulate the formulation and adoption of an improved water resource policy statement. The author argues that what is important in the case of water is not the question of ‘ownership’ of water but regulating the user rights of this common property resource, particularly since such use is always in a state of flux. In the course of its movement in the hydrological cycle, it can only be owned when it is captured in a receptacle or in an impounding tank or as treated water in a reservoir and water conveyed in an irrigation channel. But, it is this very right to abstraction of bulk water from its natural state that is not defined and left to the will of individuals and agencies – virtually resulting in the creation of a ‘free for all’ situation. While the domain of water is characterized by over 50 legislative enactments and a plethora of agencies numbering over 40, there isn’t a single neutral agency to determine the appropriate balance between the demands for off stream consumption and the volume of water flows needed by the river system. The objectives of this paper are: to clarify the meaning of the terms ‘ownership’, ‘user rights’, ‘common property rights’, and ‘right to water’; to analyze and suggest refinements to several water policy themes and issues such as ‘bulk water entitlements’, ‘groundwater management’ and ‘user conflicts’; to outline the roles of institutions for clarity in implementation; to suggest elements that should constitute a future water policy. A better understanding of the issues relating to this finite and vulnerable resource will help clarify the policy concerns that are constantly overlooked – intentionally or unintentionally - in the domain of water. Does Sri Lanka have the right water resource policies for the twenty-first century? Such concerns prompted policyholders to attempt several policy reforms in Sri Lanka’s water domain during the last five decades. Several United State Agency for International Development (USAID) and Asian Development Bank (ADB) efforts culminated in producing a ‘national water resources policy and institutional arrangement’ document with a water policy approved by the Cabinet of the Government of Sri Lanka in March 2000. Yet, public concerns expressed on certain sensitive issues, and the lack of consensus due to the changing hands of the subject of policy development among various successor ministries, resulted in the demise of this water policy formulation effort.Length: pp.113-126Water policyOwnershipGroundwater managementInstitutionsWater use
Genève, Bibliothèque de Genève, Ms. fr. 179 : Jean d’Auton, Epistre d’Hector au roy
No full textIn 1511, the Benedictine Jean d\u27Auton (around 1466-1528), chronicler at the court of Louis XII, initiated a contest to write fictional letters to the king. For this contest, he wrote the Epistre d\u27Hector au roy, which was answered, among others, by Jean Lemaire de Belges with his Epistre du roy Loys à Hector. This Geneva manuscript begins with a full-page illustration, executed by an artist named Maître des Entrées, active in Lyon. It depicts Hector presenting a book to a satyr in front of an army of soldiers in armor, some of whom are crowned with the poets’ laurel wreath. The numerous references to antiquity, textual as well as visual, are typical for the humanist milieu of Lyon, which included the owner of this manuscript, Jean Sala, half-brother of the famous author and antiquities enthusiast Pierre Sala.Online Since: 2019-10-1
Cello techniques and performing practices in the nineteenth and early twentieth centuries
No full textThis thesis comprises a study of cello performance practices throughout the nineteenth century and into the early decades of the twentieth. It is organised in terms of the increasing complexity of the concepts which it examines, as they are to be found in printed and manuscript music, instrumental methods and larger treatises, early recordings, concert reviews and pictures. Basic posture is considered along with different ways of holding the
bow. The development of the tail-pin shows that even when it was widely used, the older posture was still referred to as a model. Some implications for tone quality and tonal
projection are considered in the light of the shape of the arms. Some connections between the cellist's posture and that recommended by etiquette books are explored. The
functionality of the left hand and arm, and the development of modem scale fingerings, show that there was a considerable period of overlap between newer and older practices, with modern scale fingerings evolving over a long period of time. Similarly, views on the function of the right wrist in bowing are shown to change gradually, moving towards a more active upper arm movement with less extreme flexibility of the wrist. Two central expressive techniques especially associated with string playing arc considered in the context of the cello, namely vibrato and portamento. These topics are examined in the light of written indications in music, recommendations in cello treatises, and the practices evidenced in early recordings. The sources for this study can be brought into an overall
framework of a constant dialogue between `theory', as expressed in verbal instructions to the learner, or general a priori reflections about the cello, and `practice', manifested in performing editions and early recordings, or in individual acts of reception. A wide divergence is noted, both between theory and practice in general, and in terms of different styles of playing observable at any one time. It is suggested that tensions between practice
and critical disapproval can be resolved in terms of Lacanian discourse. Several test cases are used in order to compare several different recordings of the same works. The question of the musical character of the cello is discussed in terms of widespread assumptions about its gendered identity. A wide range of sources suggest that this moved from a straightforwardly `masculine' identity expressed through a controlling, elevated eloquence to a less clearly defined one, incorporating the 'feminine', with a greater stress on uninhibited emotional expression. Some performance implications for this change of view are pursued with respect to specific repertoires. Broad conclusions stress the importance of the diversity of performance practices as opposed to unifying generalisations
Financial liberation and adjustment in Chile and New Zealand
No full textThe authors analyze macrodynamic adjustment during financial liberalization in Chile and New Zealand. During the adjustment to more open capital accounts in the late 1970s or mid-1980s, both countries experienced appreciation of the real exchange rate and a collapse of net exports, while domestic interest rates slowly converged to international levels. The authors develop and estimate a two-sector dynamic model using both current and time-varying parameters. They find the domestic interest rate to be more responsive to shocks under imperfect capital mobility, the real exchange rate more responsive under perfect capital mobility. In short, liberalization of the capital account does not eliminate volatility but rather shifts it from the domestic interest rate to the real exchange rate.Economic Theory&Research,Macroeconomic Management,Economic Stabilization,Environmental Economics&Policies,Banks&Banking Reform
Adjoint-based adaptive convergence control of the iterative finite volume multiscale method
No full textWe propose a novel adaptive, adjoint-based, iterative multiscale finite volume (i-MSFV) method. The method aims to reduce the computational cost of the smoothing stage of the original i-MSFV method by selectively choosing fine-scale sub-domains (or sub-set of primary variables) to solve for. The selection of fine-scale primary variables is obtained from a goal-oriented adjoint model. An adjoint-based indicator is utilized as a criterion to select the primary variables having the largest errors. The Lagrange multipliers from the adjoint model can be interpreted as sensitivities of the objective function value with respect to deviations from the constraints. In case of adjoining the porous media flow equations with Lagrange multipliers, this implies that the multipliers are the sensitivities of the objective function with respect to the residuals of the flow equations, i.e., to the residual error that remains after approximately solving linear equations with the aid of an iterative solver. This allow us to recognize at which locations the solution contains more errors. More specifically, we propose a modification to the i-MSFV method to adaptively reduce the size of the fine-scale system that must be smoothed. The aim is to make the fine-scale smoothing stage less computationally demanding. To that end, we introduce a goal-oriented, adjoint-based fine-scale system reduction criterion. We demonstrate the performance of our method via single-phase, incompressible flow simulation models with challenging geological settings and using a history-matching like misfit objective function as the goal. The performance of the newly introduced method is compared to the original i-MSFV method. We investigate the adaptivity versus accuracy of the method and demonstrate how the solution accuracy varies by varying the number of unknowns selected to be smoothed. It is shown that the method can provide accurate solutions at reduced computational cost. The proof-of-concept applications indicate that the method deserves further investigations.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Reservoir EngineeringMathematical PhysicsCivil Engineering & GeosciencesGeoscience and Engineerin

Viewing political selves in film: a comparative reception study of Cuban films in Cuba and the United States
No full texttextThe author analyzed political viewing of five Cuban films in Cuba by official
cultural writers and compared this to the viewing of the same set of films by critics,
essayists, and film commentators in the United States. The analysis used Janet Staiger’s
film reception theory, the work of Michel Foucault on technologies of self, and Pierre
Bourdieu’s ideas on cultural fields and habitus as theoretical frameworks. Each set of
evidence was analyzed in relation to the types of political identities available at the time
in each country within cultural institutions, and then each set was compared with the
other. In Cuba, official workers, responding to the Cuban government’s need for
cultural policies, crafted an interpretive apparatus based in debates that explored the
relationship between aesthetics and politics. The interpretive apparatus, which the
author termed “revolutionary hermeneutics,” became a preferred rationale for
interpretation and cultural evaluation, a discipline, that shaped the Cuban cultural field
from 1958 to 1985, the period the author studied, and that cultural workers used to
interpret and value Memories of Underdevelopment (1968, d. Tomás Gutiérrez Alea),
Lucia (1968, d. Humberto Solás), One Way or Another (1974, d. Sara Gómez), Portrait
of Teresa (1979, d. Pastor Vega), and Up to a Certain Point (1983, d. Alea). U.S.
critics, influenced by the political changes of the 1960s, which made common feminist
and leftist ideas about culture and the politicization of all things Cuban, interpreted and
valued the same Cuban films with hermeneutic tactics that included anti-totalitarianism,
feminism, auteurism, and Marxism. The range of these tactics failed to show the
disciplining of the Cuban revolutionary hermeneutics but did provide evidence of the
complex ways in which cultural interpretation served U.S. cultural workers in their
negotiations of the cultural field’s relation to economic and political structures (the field
of power). As in the Cuban case, the relationship between the cultural field and the field
of power shaped the critics’ understanding of the Cuban films.Radio-Television-Fil
