Environmental change and hedonic cost functions for automobiles

This paper focuses on how changes in the economic and regulatory environment have affected production costs and product characteristics in the automobile industry. We estimate “hedonic cost functions” that relate product-level costs to their characteristics. Then we examine how this cost surface has changed over time and how these changes relate to changes in gas prices and in emission standard regulations. We also briefly consider the related questions of how changes in automobile characteristics, and in the rate of patenting, are related to regulations and gas prices.

Abrupt climate change and thermohaline circulation: Mechanisms and predictability

The ocean's thermohaline circulation has long been recognized as potentially unstable and has consequently been invoked as a potential cause of abrupt climate change on all timescales of decades and longer. However, fundamental aspects of thermohaline circulation changes remain poorly understood.

Conformational change and enhanced stabilization of the vitamin D receptor by the 1,25-dihydroxyvitamin D3 analog KH1060.

The 1,25-dihydroxyvitamin D3 [1,25-(OH)2vitamin D3] analog KH1060 exerts very potent effects on cell proliferation and cell differentiation via the vitamin D receptor (VDR). However, the activities of KH1060 are not associated with an increased affinity for the VDR. We now show that increased stabilization of the VDR-KH1060 complex could be an explanation for its high potencies. VDR half-life studies performed with cycloheximide-translational blocked rat osteoblast-like ROS 17/2.8 cells demonstrated that, in the absence of ligand, VDR levels rapidly decreased. After 2 hr, less than 10% of the initial VDR level could be measured. In the presence of 1,25-(OH)2vitamin D3, the VDR half-life was 15 hr. After 24 hr. less than 20% of the initial VDR content was detectable, whereas, at this time-point, when the cells were incubated with KH1060 80% of the VDR was still present. Differences in 1,25-(OH)2vitamin D3- and KH1060-induced conformational changes of the VDR could underlie the increased VDR stability. As assessed by limited proteolytic digestion analysis, both 1,25-(OH)2vitamin D3 and KH1060 caused a specific conformational change of the VDR. Compared with 1,25-(OH)2vitamin D3, KH1060 induced a conformational change that led to a far more dramatic protection of the VDR against proteolytic degradation. In conclusion, the altered VDR stability and the possibly underlying change in VDR conformation caused by KH1060 could be an explanation for its enhanced bioactivity.

Duplication and functional divergence in the chalcone synthase gene family of Asteraceae: evolution with substrate change and catalytic simplification.

Plant-specific polyketide synthase genes constitute a gene superfamily, including universal chalcone synthase [CHS; malonyl-CoA:4-coumaroyl-CoA malonyltransferase (cyclizing) (EC 2.3.1.74)] genes, sporadically distributed stilbene synthase (SS) genes, and atypical, as-yet-uncharacterized CHS-like genes. We have recently isolated from Gerbera hybrida (Asteraceae) an unusual CHS-like gene, GCHS2, which codes for an enzyme with structural and enzymatic properties as well as ontogenetic distribution distinct from both CHS and SS. Here, we show that the GCHS2-like function is encoded in the Gerbera genome by a family of at least three transcriptionally active genes. Conservation within the GCHS2 family was exploited with selective PCR to study the occurrence of GCHS2-like genes in other Asteraceae. Parsimony analysis of the amplified sequences together with CHS-like genes isolated from other taxa of angiosperm subclass Asteridae suggests that GCHS2 has evolved from CHS via a gene duplication event that occurred before the diversification of the Asteraceae. Enzyme activity analysis of proteins produced in vitro indicates that the GCHS2 reaction is a non-SS variant of the CHS reaction, with both different substrate specificity (to benzoyl-CoA) and a truncated catalytic profile. Together with the recent results of Durbin et al. [Durbin, M. L., Learn, G. H., Jr., Huttley, G. A. & Clegg, M. T. (1995) Proc. Natl. Acad. Sci. USA 92, 3338-3342], our study confirms a gene duplication-based model that explains how various related functions have arisen from CHS during plant evolution.

Pars triangularis asymmetry and language dominance.

The pars triangular is a portion of Broca's area. The convolutions that form the inferior and caudal extent of the pars triangularis include the anterior horizontal and anterior ascending rami of the sylvian fissure, respectively. To learn if there are anatomic asymmetries of the pars triangularis, these convolutions were measured on volumetric magnetic resonance imaging scans of 11 patients who had undergone selective hemispheric anesthesia (Wada testing) to determine hemispheric speech and language lateralization. Of the 10 patients with language lateralized to the left hemisphere, 9 had a leftward asymmetry of the pars triangularis. The 1 patient with language lateralized to the right hemisphere had a significant rightward asymmetry of the pars triangularis. Our data suggest that asymmetries of the pars triangularis may be related to speech-language lateralization.

Conceptual Decolonization of Space: Worldview and Language in Anishinaabe Akiing

This dissertation examines the role of worldview and language in the cultural framework of American Indian people. In it I develop a theory of worldview which can be defined as an interrelated set of logics that orients a culture to space (land), time, the rest of life, and provides a prescription for understanding that life. Considering the strong links between language and worldview, it is methodologically necessary to focus on a particular language and culture to decolonize concepts of and relationships to land. In particular, this dissertation focuses on an Anishinaabe worldview as consisting of four components, which are; (1) an intimate relationship to a localized space; (2) a cyclical understanding of time; (3) living in a web of relatedness with all life, and (4) understanding the world around us in terms of balance. The methodological approach draws from Anishinaabemowin, the traditional Anishinaabe language, as a starting place for negotiating a linguistic-conceptual analysis of these logics to decolonize the understandings of land, time, relatedness and balance. This dissertation helps to demonstrate that the religious language as codified in the 1st Amendment to the United States Constitution as religious freedom is unable to carry the meaning of the fundamental relationships to land that are embedded in Anishinaabemowin and culture. I compare the above Anishinaabe worldview to that of the eurowestern culture in America, which is; (1) the domination of space; (2) a linear progression of time; (3) a hierarchical organization of life; and (4) understanding the world as a Manichean battle of good versus evil. This dissertation seeks to decolonize American Indian translational methodologies and undermine the assumptions of eurowestern cultural universality.

Transcending Cultural and Language Differences: Ethical Codes of Conduct for Translators and Interpreters in Afghanistan

This project examines what an ethical code of conduct would look like in Afghanistan through analysis of historical, cultural and linguistic aspects found within its regions, as well as an examination of ethical codes of conduct for translators and interpreters in other countries. While numerous ethical guidelines and codes of conduct for translators and interpreters exist throughout global communities, it seems that creating a successful standardized ethical code of conduct in Afghanistan may be difficult to achieve given cultural and linguistic complexities. An ethical code of conduct for translators and interpreters in Afghanistan should include particular focus on: cultural sensitivity and courtesy, impartiality, conflict of interest, options for withdrawal, as well as reflect the importance of Pashtunwali.

A Theorical Point of View of Reality, Perception, and Language

It is possible to view the relations between mathematics and natural language from different aspects. This relation between mathematics and language is not based on just one aspect. In this article, the authors address the role of the Subject facing Reality through language. Perception is defined and a mathematical theory of the perceptual field is proposed. The distinction between purely expressive language and purely informative language is considered false, because the subject is expressed in the communication of a message, and conversely, in purely expressive language, as in an exclamation, there is some information. To study the relation between language and reality, the function of ostensibility is defined and propositions are divided into ostensives and estimatives.

Evaluation of the Implementation of CLIL (Content and Language Integrated Learning) Methodology in the Didactics of the English Language in Preschool Education Course Taught in the Preschool Education Teacher Undergraduate Program at the University of Alicante

Although it is known that the Spanish current Educative System promotes using the Communicate Approach to teach foreign languages in schools, other recently designed approaches are also used to help students improve their skills when communicating in a foreign language. One of these approaches is Content and Language Integrated Learning, also known as CLIL, which is used to teach content courses using the English language as the language of instruction. This approach improves the students’ skills in English as the same time as they learn content from other areas. The goal of this thesis is to present a research project carried out at the University of Alicante during the academic year 2011-2012. With this research we obtained results that provide quantitative and qualitative data which explains how the use of the CLIL methodology affects the English level of students in the “Didactics of the English Language in Preschool Education” course in Preschool Education Teacher Undergraduate Program as students acquire the contents of the course.

The impact of demographic change and its challenges for the workforce in the European public sectors. Three priority areas to invest in future HRM. EIPA Working Paper 2012/W/01

European public sectors are particularly affected by the demographic challenge and an ageing and shrinking workforce. According to OECD statistics, over 30% of public employees of central government in 13 countries will leave during the next 15 years. Moreover, the public sector has as compared to the private sector to rely on a much older workforce, who will have to work longer in future. Against this background, European governments need to react and re-think major elements of current HR and organisational management in the public sector. Particularly the skills in age management should be improved in order to also maintain in future a highly productive, competent and efficient public sector and to ensure that public employees stay longer ‘employable’, ‘healthy’, ‘fit for the job’ and ‘up to the task’. The survey suggests some solutions by investing more in three priority areas in the field of HRM.

Brazilian climate policy since 2005: continuity, change and prospective. CEPS Working Document No. 373, February 2013

In the five-year period 2005-09, Brazil has dramatically reduced carbon emissions by around 25% and at the same time has kept a stable economic growth rate of 3.5% annually. This combination of economic growth and emissions reduction is unique in the world. The driver was a dramatic reduction in deforestation in the Amazonian forest and the Cerrado Savannah. This shift empowered the sustainability social forces in Brazil to the point that the national Congress passed (December 2009) a very progressive law internalising carbon constraints and promoting the transition to a low-carbon economy. The transformation in Brazil’s carbon emissions profile and climate policy has increased the potentialities of convergence between the European Union and Brazil. The first part of this paper examines the assumption on which this paper is based, mainly that the trajectory of carbon emissions and climate/energy policies of the G20 powers is much more important than the United Nations multilateral negotiations for assessing the possibility of global transition to a low-carbon economy. The second part analyses Brazil’s position in the global carbon cycle and public policies since 2005, including the progressive shift in 2009 and the contradictory dynamic in 2010-12. The final part analyses the potential for a transition to a low-carbon economy in Brazil and the impact in global climate governance.
