International Public Opinion on China’s Climate Change Policies  [PDF]
Valerie Victoria Benguiat y Gomez
Chinese Studies (ChnStd) , 2013, DOI: 10.4236/chnstd.2013.24027
Abstract: With the emergence of a global public sphere and the revolution of global media, international public opinion has gained an intrinsic importance for effective multilateral cooperation. Global governance initiatives are subject to international public opinion, and climate change is the single most important global governance issue of our time. Tackling climate change requires a fundamental transformation of the global economy, with an emphasis on sustainable development. Due to its political and economic weight, China can push forward UN climate change negotiations, and can do so without compromising its national development goals (China’s National Climate Change Programme, 2007). China’s national policies are beyond what is required from developing nations, but international public opinion often perceives a different message. This paper holds that a national branding strategy will help convey China’s current efforts, allowing a better understanding among nations in order to break the climate change negotiations deadlock. This research merged perception analysis and public opinion surveys with mass media qualitative and quantitative analysis to gain a full insight into what the international climate change decision-makers, opinion-leaders and general public think about China’s position at the UNFCCC negotiations. As seen in the findings of the present research, the climate of opinion is unfavorable to China. Overall, the results show that China is perceived as a negative influence in the negotiations. China’s climate change efforts are being overlooked by international public opinion. But the reason lies in China’s current discourse, where climate change and the environment are always downplayed by the right to develop (D’Hooghe, 2011). According to China’s 12th Five Year Plan, the new path for the country is marked by its commitment to achieve growth through low carbon development, with a strong focus on addressing climate change and energy challenges (Shealy & Dorian, 2007). The results of this study show that the positive intentions and actions of the Chinese government aren’t being accurately perceived by public opinion. The empirical findings in this study provide a new understanding of one specific part of the overall image that the world has about China. Whilst this study did not confirm unequivocally that international public opinion directly determines the outcomes of international negotiations and foreign policy, it did partially substantiate the concept that there’s a correlation between China’s public declarations and actions, the

Abstract: The objective of this work is a reflection on the ethics of education on the net as a contribution to the face-to-face interaction in the virtual world. We think the ethics is a result of a process of responsible interchange with others. Two important thinkers of the last few decades, Emmanuel Levinas e Paulo Freire contribute each one with one’s unique approach to the questions surrounding ethic in the online education: ethic of responsibility and humanist ethic. Almost no attention has been paid to examining their views on ethic in online education, but this article, in part, fulfills a gap and attempts to mediate their two positions towards a broader critique of face-to-face in virtual world. This work shows some implications of interaction in the virtual world and questions the possibility of the paradox of face-to-face being virtual. The experiences as a professor of web-courses about Paulo Freire, at Latin American Council of Social Sciences and the theoretical revision (Freire, 1970, 1999, Levinas, 1980, 1997, Gomez, 2004,) contribute to this reflection. The results suggest that ethics of responsibility does not allow fleeing from the Other who demands attention, listening and dialog to speed up the learning process. By utilizing both Levinas and Freire, it is argued, against a conservative pedagogy based on an instrumental ethic and in favour of a participatory pedagogy that can help strengthen the learning.

Abstract: ABSTRACT Freire's cogitation on Information Technology (IT), resources for education have been known since the decade of the 50s. And now, within the current context, this analysis outlines the literacy problem as an issue of gnosis and anthropology while existing in a virtual dimension. Based on research/experiences that also were carried out in Brazil, it can be noted that the literacy that is being discussed includes the skill in handling a mouse, selecting, dragging, cutting, pasting, CTRL C+CTRL V, writing a text and searching the internet, but although it seems "obvious", public education policy has not given sufficient thought nor assumed a pedagogical position on these issues. This discussed cogitation considers contributions of the Freire pedagogy, in the attempt to attain, through this type of literacy, the unprecedented accomplishment of something viable–that what teachers realize as unprecedented, due to the fact that nobody has accomplished it before, however viable, because all of the conditions to make it happen are there, including a critical preparation of the educators. Within the internet context, the proposal implies a digital writing and reading ability that is based on communication and dialogue skills and, as fundamental strategies for reading the world, the real/virtual world,the knowledge of the daily speech, of writing and reading within a multi-diversification of digitally generated texts.
Génesis de suelos y evolución del paisaje en el delta del río Paraná Soil genesis and landscape evolution in the Parana River Delta

Revista de la Asociación Geológica Argentina , 2004,
Abstract: Se analizan las relaciones existentes entre la evolución y distribución de los suelos y las características del paisaje en un sector del delta del Paraná en la provincia de Entre Ríos (33°00'-33°45'S y 58°30'-59°17'O). El delta del Paraná ha tenido una compleja evolución geomorfológica y geológica debida a la interacción entre el proceso fluvial, las ingresiones marinas y las acciones eólicas. Han sido diferenciadas nueve unidades geomórficas: 1) Faja aluvial del río Gualeguay, 2) Faja aluvial del Arroyo. ancay, 3) Fajas aluviales de los cursos menores, 4) Delta del río Gualeguay, 5) Planicie deltaica; 6) Cordones litorales, 7) Antigua albúfera y planicie de marea; 8) Planicie de deflación y acumulación eólica y 9) Dunas. Los suelos son principalmente Entisoles, Inceptisoles y Molisoles, reconociéndose una sucesión espacial de los mismos. La evolución de los suelos ha sido controlada por 1) una activa morfodinámica, 2) la existencia de características geomorfológicas que resultan en un régimen ácuico y 3) las fluctuaciones climáticas cuaternarias plasmadas en variaciones del nivel del mar. Finalmente, se estudian la distribución y principales propiedades de los suelos en relación con las características y evolución del paisaje. The relationships between landscapes features evolution and soil genesis and distribution are studied. The area is located in southern Entre Rios province (33°00'-33°45'S and 58°30'-59°17'W). The Parana River Delta, has a complex genetic evolution, due to river processes, marine ingressions and aeolian actions. These processes resulted in an unstable landscape, that imprinted its particular features in soils. Nine geomorphic units were recognized: 1) Gualeguay river alluvial plain and terraces, 2) Arroyo ancay aluvial plain and terrazes, 3) Minor streams aluvial plains, 4) Gualeguay river delta, 5) Deltaic plain, 6) Beach ridges, 7) Old lagoon and tidal plain, 8) Loessic plain and 9) Dunes. Soils are mainly Entisols, Inceptisols and Mollisols, and a spatial trend is recognized in the Delta Region. Soil evolution is controlled by a) an active morphodynamic, b) soil landscape features that resulted in a dominant aquic regime of soils and c) Late Quaternary climatic fluctuations that resulted in sea level variations. Finally, soil development, soil features and distribution and soil drainage are studied in relation with landscape main features and evolution.

Abstract: We have conditionally deleted the Adenomatous Polyposis coli gene (Apc) from the adult murine intestine in wild type and p53 deficient environments and subsequently compared the phenotype and transcriptome profiles in both genotypes.Expression of p53 was shown to be elevated following the conditional deletion of Apc in the adult small intestine. Furthermore, p53 status was shown to impact on the transcription profile observed following Apc loss. A number of key Wnt pathway components and targets were altered in the p53 deficient environment. However, the aberrant phenotype observed following loss of Apc (rapid nuclear localisation of β-catenin, increased levels of DNA damage, nuclear atypia, perturbed cell death, proliferation, differentiation and migration) was not significantly altered by the absence of p53.p53 related feedback mechanisms regulating Wnt signalling activity are present in the intestine, and become activated following loss of Apc. However, the physiological Wnt pathway regulation by p53 appears to be overwhelmed by Apc loss and consequently the activity of these regulatory mechanisms is not sufficient to modulate the immediate phenotypes seen following Apc loss. Thus we are able to provide an explanation to the apparent contradiction that, despite having a Wnt regulatory capacity, p53 loss is not associated with early lesion development.p53 is implicated in colorectal cancer as the final step of multi-step carcinogenesis leading to carcinoma formation [1]. However, p53 is also postulated to be involved as a critical negative regulator of the Wnt signalling pathway, arguing that it should also have a role in the tumour initiation process. To date, crossing p53 deficient mice to the Apcmin mouse has variably been reported to have no effect or to modify adenoma formation [2-4]. Consequently there is a need to further clarify the role of p53 function in intestinal neoplasia.Increased levels of β-catenin lead to increased transcription of p14ARF (in huma
Adaptive Radiation for Lung Cancer
Daniel R. Gomez,Joe Y. Chang
Journal of Oncology , 2011, DOI: 10.1155/2011/898391
Abstract: The challenges of lung cancer radiotherapy are intra/inter-fraction tumor/organ anatomy/motion changes and the need to spare surrounding critical structures. Evolving radiotherapy technologies, such as four-dimensional (4D) image-based motion management, daily on-board imaging and adaptive radiotherapy based on volumetric images over the course of radiotherapy, have enabled us to deliver higher dose to target while minimizing normal tissue toxicities. The image-guided radiotherapy adapted to changes of motion and anatomy has made the radiotherapy more precise and allowed ablative dose delivered to the target using novel treatment approaches such as intensity-modulated radiation therapy, stereotactic body radiation therapy, and proton therapy in lung cancer, techniques used to be considered very sensitive to motion change. Future clinical trials using real time tracking and biological adaptive radiotherapy based on functional images are proposed. 1. Introduction The treatment of lung cancer with radiation has undergone significant improvements over the past decade. These improvements can be grouped under three different categories. First, it is possible to better delineate the target volume through the advancement of imaging such as positron emission tomography (PET) fusion [1, 2]. Second, there has been an increase in the utilization of radiation planning and delivery systems such as intensity-modulated radiation therapy (IMRT) [3], stereotactic body radiation therapy (SBRT) [4], and proton therapy [5] that allow more conformal delivery of radiation to achieve dose escalation while minimizing toxicity to normal structures [6, 7]. Finally, the advancement of imaging modalities available during the planning and delivery process has made it feasible to adapt the target volume, both within a given fraction of treatment and between fractions, for such factors as internal motion, tumor response, anatomical changes, and weight loss. With the availability of 4D CT—(four-dimensional computerized tomography)—based radiotherapy planning and on-board imaging (OBI), accurate positioning of the target using daily image guidance may result in many advantages, such as a decreased probability of target miss, smaller setup margins, and less normal tissue exposed to high radiation doses. In addition, novel treatment adaptation algorithms can provide more effective modification of treatment plans to adapt to the changes in a patient’s anatomy and organ motion during and/or between (intra- and/or inter-) treatment fractions. This latter category of innovations has been
Impairments in Background and Event-Related Alpha-Band Oscillatory Activity in Patients with Schizophrenia

Abstract: Studies show that patients with schizophrenia exhibit impaired responses to sensory stimuli, especially at the early stages of neural processing. In particular, patients’ alpha-band (8–14 Hz) event-related desynchronization (ERD) and visual P1 event-related potential (ERP) component tend to be significantly reduced, with P1 ERP deficits greater for visual stimuli biased towards the magnocellular system. In healthy controls, studies show that pre-stimulus alpha (background alpha) plays a pivotal role in sensory processing and behavior, largely by shaping the neural responses to incoming stimuli. Here, we address whether patients’ ERD and P1 deficits stem from impairments in pre-stimulus alpha mechanisms. To address this question we recorded electrophysiological activity in patients with schizophrenia and healthy controls while they engaged in a visual discrimination task with low, medium, and high contrast stimuli. The results revealed a significant decrease in patients’ ERDs, which was largely driven by reductions in pre-stimulus alpha. These reductions were most prominent in right-hemispheric areas. We also observed a systematic relationship between pre-stimulus alpha and the P1 component across different contrast levels. However, this relationship was only observed in healthy controls. Taken together, these findings highlight a substantial anomaly in patients’ amplitude-based alpha background activity over visual areas. The results provide further support that pre-stimulus alpha activity plays an active role in perception by modulating the neural responses to incoming sensory inputs, a mechanism that seems to be compromised in schizophrenia.
