Turnitin Adoption and Application at a HEI: A Developmental Approach  [PDF]
Juliet Stoltenkamp, Martha Kabaka
Creative Education (CE) , 2014, DOI: 10.4236/ce.2014.512118
Abstract: Issues of plagiarism are mutual debates across Higher Education Institutions (HEI). As a result, institutions have employed software detection tools as a measure to deter such unacceptable academic practices. This study explores experiences related to the adoption and implementation of Turnitin (Tii) perspective through a developmental approach at a HEI, namely, the University of the Western Cape (UWC), South Africa, during the period 2010 January to 2013 June . A case study approach was adopted targeting the lecturers, their assistants and Centre for Innovative Educational and Communication Technologies (CIECT) Tii support team members. Qualitative research design was applied. This was in addition to an analysis of data collected from post-Tii training workshop evaluation questionnaires, and random email enquiries and responses between lecturers and the CIECT team on Tii matters. The paper reflects on the slow uptake of Tii by the lecturers, which is worrisome as the students are dependent on their commitment. The support team encourages a developmental, rather than a punitive approach. Students need to be encouraged by their lecturers to submit assignments and subsequently improve on their academic writing according to originality reports retrieved from Tii. The researchers hope that these findings would highlight the importance of the dissemination of an anti-plagiarism document which will enable plagiarism discourse.
Functional Foods for Obesity Management  [PDF]

Food and Nutrition Sciences (FNS) , 2014, DOI: 10.4236/fns.2014.514148

Obesity is a global problem and numbers are rising at a fast pace in developing countries and it becomes a major public health concern. Economic costs associated with obesity are high and increasing as the rate of obesity. Obesity leads to its co-morbidities; namely diabetes, hypertension, cardiovascular diseases, osteoarthritis, stroke and inflammatory diseases. Changes in life-style along with modifications to the diet are important in the management of obesity. Certain dietary components and foods have the ability to induce thermogenesis and modify the trafficking of nutrients in the body. Positive effects in managing obesity by natural components, and selected foods have drawn attention due to the potential side effects of obesity drugs. The food industry has developed low-density foods to reduce energy intake. Now focus has been geared towards the development of foods that possess more than one mechanism to alter the progression of obesity. In this review, selected foods and their components with potential anti-obesity properties are discussed.

Anti-Inflammatory Properties of Sirtuin 6 in Human Umbilical Vein Endothelial Cells
Martha Lappas
Mediators of Inflammation , 2012, DOI: 10.1155/2012/597514
Abstract: A prominent feature of inflammatory diseases is endothelial dysfunction. Factors associated with endothelial dysfunction include proinflammatory cytokines, adhesion molecules, and matrix degrading enzymes. At the transcriptional level, they are regulated by the histone deacetylase sirtuin (SIRT) 1 via its actions on the proinflammatory transcription factor nuclear factor- B (NF- B). The role of SIRT6, also a histone deacetylase, in regulating inflammation in endothelial cells is not known. The aim of this study was to determine the effect of SIRT6 knockdown on inflammatory markers in human umbilical vein endothelial cells (HUVECs) in the presence of lipopolysaccharide (LPS). LPS decreased expression of SIRT6 in HUVECs. Knockdown of SIRT6 increased the expression of proinflammatory cytokines (IL-1 , IL-6, IL-8), COX-prostaglandin system, ECM remodelling enzymes (MMP-2, MMP-9 and PAI-1), the adhesion molecule ICAM-1, and proangiogenic growth factors VEGF and FGF-2; cell migration; cell adhesion to leukocytes. Loss of SIRT6 increased the expression of NF- B, whereas overexpression of SIRT6 was associated with decreased NF- B transcriptional activity. Taken together, these results demonstrate that the loss of SIRT6 in endothelial cells is associated with upregulation of genes involved in inflammation, vascular remodelling, and angiogenesis. SIRT6 may be a potential pharmacological target for inflammatory vascular diseases. 1. Introduction Endothelial dysfunction is associated with vasoconstriction, a proinflammatory state, and prothrombotic properties. A number of diseases, including most forms of cardiovascular disease, diabetes, cancer, rheumatoid arthritis, and aging, are associated with endothelial dysfunction [1–3]. Endothelial dysfunction is also a characteristic of bacterial sepsis [4, 5]. To reduce or prevent the high incidence of morbidity and mortality associated with vascular complications, it is essential to understand further the mechanism by which inflammation regulates endothelial function. Systemic inflammation causes an upregulation of a wide number of factors that lead to severe injury of vascular endothelial cells [6–10]. These include growth factors (basic fibroblast growth factor (bFGF or FGF-2), vascular endothelial growth factor (VEGF)); proinflammatory cytokines (IL-1 , IL-6) and chemokines (IL-8); extracellular matrix (ECM) degrading enzymes (plasminogen activator inhibitor-1 (PAI-1), matrix metalloproteinases (MMPs)); cell adhesion molecules (intercellular adhesion molecule (ICAM-1), vascular cell adhesion protein (VCAM)-1,
Formación docente, el otro y las huellas para anticipar la ense?anza y el aprendizaje: Dialogando con Zambrano, desde Meirieu
Educere , 2009,
Abstract: the paper takes contributions from p meireieu?s theory, reviews his main work and talks them over with conceptualizations made by armando zambrano leal. it also reflects on some aspect of education, amongst them the possibility of thinking that it requires revisiting the conditions to teach and the acknowledgement of the ?other? as a subject. another axis from the paper, refers to the concern from the teacher meirieu mentions in his works, understanding it as a social actor made out of a didactical knowledge which is not just a technique, but a complex theory. otherwise we would be talking, according to the author, about ?methodologists,? from a technocratic paradigm far from the problematization of contents and subjects in a hermeneutical sense. finally, it gets back the difficulty of teacher education when the difficulties related to the teacher?s educational power are foreseen and the possibility of escaping from the power of that who educates the teacher.
Estado y política agraria en la frontera sur argentina: el territorio nacional de Río Negro (1916-1930)
Ruffini, Martha;
Estudios fronterizos , 2009,
Abstract: the president hipólito yrigoyen, leader of the radical civic union party (1916-1930), took office in 1916. he promoted a policy which supposedly pretended to rectify the previous "conservative order". the implementation of such policy in the national territories -real internal borders of the national state- was easier due to the administrative and political centralization of those territories, resulting in an appropriate perspective to interpreter the state's conduct as well as its interests and motivations. in this article we intended to analyze the state-territories relation through a case study: the national territory of río negro, a very old inhabited place on the south border, in the north of the patagonia, which since its establishment needed the state's decision to get through the determining factors for the agricultural development. nevertheless, the radical government would not get away from the prevailing agricultural policy and would show difficulties in overcoming certain obstacles, related to the navigability of the river negro and its periodic floods, destructive of any sustainable farming progress.
A pesquisa educacional e a produ??o de saberes nos museus de ciência
Marandino, Martha;
História, Ciências, Saúde-Manguinhos , 2005, DOI: 10.1590/S0104-59702005000400009
Abstract: the article examines the processes by which scientific knowledge is socialized, based on the concepts of museographic/didactical transposition and recontextualization within the realm of science museums. ways of producing knowledge in museums are analyzed, alongside a discussion of the potential challenges and possibilities involved when applying these concepts to research on dissemination and education in a museum setting. some considerations are advanced on how these may contribute to the development of pedagogical practice in museums. the processes by which scientific knowledge is transformed for the purpose of educating and disseminating knowledge do not merely simplify ideas and concepts, since new knowledge is constructed inside the realm of museum culture.
Historia Crítica , 2011,
Abstract: in this article, we argue that the category of gender is a key conceptual tool with which to interpret the significance of actions of men and women in cultural, social, and political realms of any society furrowed by relations of power. although the scope of the notion is wide, our interest is studying how gender relations were inscribed during the democratic revolutions at the turn of the nineteenth century in new granada. we seek to demonstrate the significance of the category of gender to understand the constitution of the new social order, since it was fundamental to both the deconstruction of the colonial order and the reconstruction of the republican order. we provide a brief overview of how the category acquired a place within the social sciences. we also spend some time discussing the relationship between democracy, citizenship, and gender, referring to work that, in the study of communities and their practices, have highlighted how popular classes, which were initially excluded from citizenship, participated in politics, negotiating with local, regional, or national values.
A biologia nos museus de ciências: a quest?o dos textos em bioexposi??es
Marandino, Martha;
Ciência & Educa??o (Bauru) , 2002, DOI: 10.1590/S1516-73132002000200004
Abstract: this paper discusses the process of elaborating texts to be used in science museums. it is based on data from a phd thesis that studied the process of transformation of scientific discourse - particularly biological - into expositive discourse in the construction of exhibitions at science museums. initially, the paper deals with theoretical references on the scientific text, the public communication text and the text presented in museum exhibitions. examples of texts taken from five exhibitions were presented, based on data obtained through qualitative analysis. aspects such as form, structure, editing and language were analyzed, aiming at showing the differences among the three kinds of text mentioned above. also, these aspects were used to characterize the recontextualization process that occurs when the expositive discourse is produced. in conclusion, one can say that the texts from science museums are different from scientific or public communication texts, despite their having common elements. it is necessary to understand the specificities of the museum culture and of the visiting public, in order to improve the production of science museum texts. further research on evaluation of science museum texts is desirable if more and better reading of them is to be stimulated.
ACTORES NO GUBERNAMENTALES Y POLíTICA EXTERIOR: A propósito del sector académico y el dise?o de la política exterior migratoria colombiana
Colombia Internacional , 2009,
Abstract: during the last few years non-governmental actors have gained strength in seeking, in many cases, to promote sensibility and influence foreign policy. in their specific case, and unlike in other countries, the colombian foreign policy decision-makers seldom interact with entities other than the state. in this article, a case study is examined in which the academic sector has been consulted on the characteristics of migrants and the design of a migratory foreign policy. by doing so, it seeks to examine the influence of the academic sector in the design and execution of said regulations. it concludes that its participation has been circumstantial, punctual and intermittent.
La Patagonia en el pensamiento y la acción de un reformista liberal: Ezequiel Ramos Mexía (1852-1935)
Quinto sol , 2008,
Abstract: at the beginning of the 20th century the ruling sector of the national state evidenced important fractures.the battle between those who were demanding the continuity of the excluding politic modality against those who were claiming for the opening of the political system was an important characteristic of evident breaks within conservatism. in the context of replacements and reformists rearrangements we locate ezequiel ramos mexía, as an active intellectual, minister of agriculture (1901-1906) and national public constructions (1907-1913). his importance lies not only in his public trajectory but also in the corpus of ideas and projects that he posed during his political performance stated in his written production, in the debates at the national congress and also in the dispute with national employees. his ideas reflect the dominant conceptions about order and progress, with a particular vision concerning public lands and the southern native peoples. his proposals about the qualification of new areas to settle immigrants, moving them further away from most populated areas (considered as an exposure to higher political agitation), concluded in a plan for patagonia, which appears as an attempt of response, from an economic approach, to the so called "social affair".
