Getting the big picture: Development of spatial scaling abilities

Spatial scaling is an integral aspect of many spatial tasks that involve symbol-to-referent correspondences (e.g., map reading, drawing). In this study, we asked 3–6-year-olds and adults to locate objects in a two-dimensional spatial layout using information from a second spatial representation (map). We examined how scaling factor and reference features, such as the shape of the layout or the presence of landmarks, affect performance. Results showed that spatial scaling on this simple task undergoes considerable development, especially between 3 and 5 years of age. Furthermore, the youngest children showed large individual variability and profited from landmark information. Accuracy differed between scaled and un-scaled items, but not between items using different scaling factors (1:2 vs. 1:4), suggesting that participants encoded relative rather than absolute distances.

Image-based vs. mesh-based statistical appearance models of the human femur: Implications for finite element simulations.

Statistical appearance models have recently been introduced in bone mechanics to investigate bone geometry and mechanical properties in population studies. The establishment of accurate anatomical correspondences is a critical aspect for the construction of reliable models. Depending on the representation of a bone as an image or a mesh, correspondences are detected using image registration or mesh morphing. The objective of this study was to compare image-based and mesh-based statistical appearance models of the femur for finite element (FE) simulations. To this aim, (i) we compared correspondence detection methods on bone surface and in bone volume; (ii) we created an image-based and a mesh-based statistical appearance models from 130 images, which we validated using compactness, representation and generalization, and we analyzed the FE results on 50 recreated bones vs. original bones; (iii) we created 1000 new instances, and we compared the quality of the FE meshes. Results showed that the image-based approach was more accurate in volume correspondence detection and quality of FE meshes, whereas the mesh-based approach was more accurate for surface correspondence detection and model compactness. Based on our results, we recommend the use of image-based statistical appearance models for FE simulations of the femur.

Perpetual Conflict or Compromise? The Cost of Domestic Legitimacy in the Realm of Women's Human Rights: A Case Study on the Right to an Abortion

With its turbulent and volatile legal evolution, the right to an abortion in the United States still remains a highly contested issue and has developed into one of the most divisive topics within modern legal discourse. By deconstructing the political underpinnings and legal rationale of the right to an abortion through a systematic case law analysis, I will demonstrate that this right has been incrementally destabilized. This instability embedded in abortion jurisprudence has been primarily produced by a combination of textual ambiguity in the case law and judicial ambivalence regarding this complex area of law. In addition, I argue that the use of the largely discredited substantive due process doctrine to ground this contentious right has also contributed to the lack of legal stability. I assert that when these elements culminate in the realm of reproductive privacy the right to terminate a pregnancy becomes increasingly unstable and contested.

Walter Chatton y Adam of Wodeham : dos perspectivas medievales funcionalistas sobre la naturaleza de algunos estados mentales

En este artículo tenemos como objetivo mostrar que, por una parte, en oposición a la teoría de William of Ockham, las teorías de Walter Chatton y Adam of Wodeham convienen con la doctrina contemporánea según la cual los estados mentales son estados funcionales de un cierto tipo. Por otra parte, en este artículo queremos revelar que aquellas teorías medievales que podemos llamar funcionalistas fundamentan una perspectiva económica medieval respecto a la composición de un ser humano.

A taste of the technical cuisine: metals and other ingredients

According to cognitive linguistics, language has an experiential origin based on perception, sensory motor activities and our knowledge of the world. Our thought operates by establishing similarities, links and associations that enable us to talk about one thing in terms of another as shown in the example of love as a journey (Lakoff and Johnson, 1980). Metaphor and metonymy are conceptual and linguistic tools that make possible most of these cognitive operations. Since metaphor is an essential element of human communication, the discourse of specialised disciplines includes metaphorical mappings and numerous examples of metaphorical expressions, for example in economics, where business is mapped in terms of war (White, 2004; Herrera & White, 2000), electrotechnics with electrical components understood as couples (Roldán- Riejos in preparation) or in civil engineering where a bridge is conceptualized as a person (Roldán-Riejos, 2013). In this paper, the metaphors: WORKING WITH METALS IS COOKING/ TRABAJAR CON METALES ES COCINAR and METALS ARE CULINARY OBJECTS/ LOS METALES SON OBJETOS CULINARIOS are explored. The main aim is to show that the cooking metaphor is widely spread in the metallurgical domain in English and Spanish, although with different nuances in each language due to socio-cultural factors. The method adopted consists of analysing examples taken from the: Bilingual Dictionary of Scientific and Technical Metaphors and Metonymies Spanish- English/English-Spanish, a forthcoming and rigorously documented bilingual dictionary that sums up research on conceptual, linguistic and visual metaphor and metonymy in different areas of engineering (Roldán-Riejos and Molina, 2013). The present paper studies in detail English and Spanish cross-linguistic correspondences related to types of metals and processes. It is suggested that they reflect synesthetic metaphoric mappings. The exploitation of cognitive conceptual metaphor in the ESP classroom is lastly recommended.

An economic analysis of unilateral refusals to license intellectual property

The intellectual property laws in the United States provide the owners of intellectual property with discretion to license the right to use that property or to make or sell products that embody the intellectual property. However, the antitrust laws constrain the use of property, including intellectual property, by a firm with market power and may place limitations on the licensing of intellectual property. This paper focuses on one aspect of antitrust law, the so-called “essential facilities doctrine,” which may impose a duty upon firms controlling an “essential facility” to make that facility available to their rivals. In the intellectual property context, an obligation to make property available is equivalent to a requirement for compulsory licensing. Compulsory licensing may embrace the requirement that the owner of software permit access to the underlying code so that others can develop compatible application programs. Compulsory licensing may undermine incentives for research and development by reducing the value of an innovation to the inventor. This paper shows that compulsory licensing also may reduce economic efficiency in the short run by facilitating the entry of inefficient producers and by promoting licensing arrangements that result in higher prices.

Alpha-helical, but not beta-sheet, propensity of proline is determined by peptide environment.

Proline is established as a potent breaker of both alpha-helical and beta-sheet structures in soluble (globular) proteins. Thus, the frequent occurrence of the Pro residue in the putative transmembrane helices of integral membrane proteins, particularly transport proteins, presents a structural dilemma. We propose that this phenomenon results from the fact that the structural propensity of a given amino acid may be altered to conform to changes imposed by molecular environment. To test this hypothesis on proline, we synthesized model peptides of generic sequence H2N-(Ser-LyS)2-Ala- Leu-Z-Ala-Leu-Z-Trp-Ala-Leu-Z-(Lys-Ser)3-OH (Z = Ala and/or Pro). Peptide conformations were analyzed by circular dichroism spectroscopy in aqueous buffer, SDS, lysophosphatidylglycerol micelles, and organic solvents (methanol, trifluoroethanol, and 2-propanol). The helical propensity of Pro was found to be greatly enhanced in the membrane-mimetic environments of both lipid micelles and organic solvents. Proline was found to stabilize the alpha-helical conformation relative to Ala at elevated temperatures in 2-propanol, an observation that argues against the doctrine that Pro is the most potent alpha-helix breaker as established in aqueous media. Parallel studies in deoxycholate micelles of the temperature-induced conformational transitions of the single-spanning membrane bacteriophage IKe major coat protein, in which the Pro-containing wild type was compared with Pro30 --> Ala mutant, Pro was found to protect the helix, but disrupt the beta-sheet structure as effectively as it does to model peptides in water. The intrinsic capacity of Pro to disrupt beta-sheets was further reflected in a survey of porins where Pro was found to be selectively excluded from the core of membrane-spanning beta-sheet barrels. The overall data provide a rationale for predicting and understanding the structural consequences when Pro occurs in the context of a membrane.

The First Century of Right to Arms Litigation

This Article examines state court cases involving the right to arms, during the first century following ratification of the Amendment in 1791. This is not the first article to survey some of those cases. This Article includes additional cases, and details the procedural postures and facts, not only the holdings. The Article closely examines how the Supreme Court integrated the nineteenth century arms cases into Heller and McDonald to shape modern Second Amendment law. Part I briefly explains two English cases which greatly influenced American legal understandings. Semayne’s Case is the foundation of “castle doctrine” — the right to home security which includes the right of armed self-defense in the home. Sir John Knight’s Case fortified the tradition of the right to bear arms, providing that the person must bear arms in a non-terrifying manner. Part II examines American antebellum cases; these are the cases to which Heller looked for guidance on the meaning of the Second Amendment. Part III looks at cases from Reconstruction and the early years of Jim Crow, through 1891. As with the antebellum cases, the large majority of post-war cases are from the Southeast, which during the nineteenth century was the region most ardent for gun control. The heart of gun control country was Tennessee and Arkansas; courts there resisted some infringements of the right to arms, but eventually gave up. Heller and McDonald did not look to the Jim Crow cases as constructive precedents on the Second Amendment.

Slaying the Hydra: Al Qaeda's Evolution and America's Plan of Attack

In response to 9/11, the U.S. launched airstrikes in Afghanistan against al Qaeda to diminish its ability to conduct future attacks. Next, the U.S. turned its attention to Iraq. A series of problems and missteps there subsequently created an opportunity for al Qaeda to evolve, aligning itself with active insurgencies and other terrorist groups around the world. This paper identifies the largely preemptive strategies employed by the U.S. and analyzes how those efforts positively and negatively impacted the War on Terror. While some significant gains were made, the results show that al Qaeda remains a threat to the international community and demands more effective U.S. and international counter-radicalization strategies, including diplomacy and aid, to curb its global appeal.

Topological structures of complex belief systems

The concepts of substantive beliefs and derived beliefs are defined, a set of substantive beliefs S like open set and the neighborhood of an element substantive belief. A semantic operation of conjunction is defined with a structure of an Abelian group. Mathematical structures exist such as poset beliefs and join-semilattttice beliefs. A metric space of beliefs and the distance of belief depending on the believer are defined. The concepts of closed and opened ball are defined. S′ is defined as subgroup of the metric space of beliefs Σ and S′ is a totally limited set. The term s is defined (substantive belief) in terms of closing of S′. It is deduced that Σ is paracompact due to Stone's Theorem. The pseudometric space of beliefs is defined to show how the metric of the nonbelieving subject has a topological space like a nonmaterial abstract ideal space formed in the mind of the believing subject, fulfilling the conditions of Kuratowski axioms of closure. To establish patterns of materialization of beliefs we are going to consider that these have defined mathematical structures. This will allow us to understand better cultural processes of text, architecture, norms, and education that are forms or the materialization of an ideology. This materialization is the conversion by means of certain mathematical correspondences, of an abstract set whose elements are beliefs or ideas, in an impure set whose elements are material or energetic. Text is a materialization of ideology.

The new bail-in doctrine: A recipe for banking crises and depression in the eurozone. CEPS Commentary

This Commentary argues that the failure to recognise shared responsibility for the banking crisis in Cyprus has led to the imposition of a bail-in template that increases the risk of banking crises and economic depression in the eurozone.

Discretion and Accountability: The ESMA Judgment and the Meroni Doctrine. Bruges European Economic Research (BEER) Papers 30/2014

This paper assesses the effectiveness of the Meroni doctrine in the light of the recent judgment in the ESMA case. The first part explains in detail the problem of delegation of powers in the EU from the perspective of the principal-agent theory and complements it with the analysis of the trade-off between different levels of independence and accountability of agencies. A simple economic model is developed to illustrated the relationship between the independence and accountability of an agency. It shows that it is the accountability mechanism that induces the agent to act, rather than the extent of his independence. The paper also explains the inter-temporal interactions between the principal and the agent on the basis of the incentives in place for the different players. The second part is devoted to analysis of the functioning of ESMA in the context of its delegated powers. After the presentation of main aspects of the regulatory framework establishing ESMA, the paper continuous with an analysis and interpretation of the discretionary powers of ESMA. The rather rigid position of the Court of Justice in relation to the Meroni doctrine seems to be unsuitable to delegation of complex regulatory tasks. This is particularly evident in the case of financial markets. Finally, the judgment does not examine in any detail whether and how the principals - i.e. the EU and Member States - are best able to evaluate the quality of ESMA decisions and regulations and whether there are different but more effective accountability mechanisms.

Unfair Advantage: An Intriguing Example of Legal Transformation in the Swiss Private Law

This paper demonstrates a mixed approach to the theme of the instrumentality of law by both analysing the goal of a legal transformation and the techniques adapted to achieve it. The correct recognition of a certain practical necessity has lead the Swiss Federal Tribunal to an intriguing judgement “Fussballclub Lohn-Fall” of 1997. The legal remedies provided for cases of unfair advantage have been then creatively modified praeter legem. The adaptation was strongly influenced by foreign legal patterns. The Swiss Code of Obligations of 1911 provides a norm in art. 21 on unfair advantage (unconscionable contract), prescribing that if one party takes unjustified advantage over the weaknesses of another in order to receive an excessive benefit, such a contract is avoidable. Its wording has been shaped over a hundred years ago and still remains intact. However, over the course of the 20th century the necessity for a more efficient protection has arisen. The legal doctrine and jurisprudence were constantly pointing out the incompleteness of the remedies provided by art. 21 of the Code of Obligations. In the “Fussballclub Lohn-Fall” (BGE 123 III 292) the Swiss Federal Tribunal finally introduced the possibility to modify the contract. Its decision has been described as “a sign of the zeitgeist, spirit of the time”. It was the Swiss legal doctrine that has imposed the new measure under the influence of the German “quantitative Teilnichtigkeit” (quantitative partial nullity). The historical heritage of the Roman laesio enormis has also played its role.
